Fig. 1 is a schematic structural diagram of an electric grass trimmer 100 according to an exemplary embodiment, and Fig. 2 is a schematic structural diagram of a host 1 according to an exemplary embodiment. As shown in Figure 1-2, the electric grass trimmer 100 may include a host 1, a push rod 2 and a base 3, wherein the host 1 can be detachably assembled with the base 3, and the base 3 can be connected with the push rod 2, so that the user You can hold the push rod 2 to push the electric grass trimmer 100 forward or in other target directions, so as to cut green plants in various areas. Or, as shown in Figure 2, the user can also disassemble the push rod 2 and the base 3, and hold the main unit 1 to prune the green plants, which can be selected according to the height and position of the green plants to be trimmed, which is not discussed in this application. Limit. In fact, as shown in Figure 2, the host 1 can be equipped with a short knife to comb the green plants. In other embodiments, as shown in Figure 3, the host 1 can also be equipped with a long knife to trim the lawn or green plants. The tool suitable for the current pruning object can be selected according to actual needs, which is not limited in the present application. In the following, the technical solution of the present application will be described in detail by taking the host machine 1 equipped with a long tool as an example.

As shown in FIGS. 3-6 , the host 1 may include a casing 11 , a motor assembly 12 , a battery pack 13 and a first switch assembly 14 . Wherein, the motor assembly 12 can be assembled in the housing 11 and the motor assembly 12 can also be connected with the cutter, so that the motor assembly 12 can drive the cutter to move, so as to realize the trimming of green plants. The housing 11 can also include a battery compartment 111, in which the battery pack 13 is detachably assembled, and the battery pack 13 can provide power for the motor assembly 12, so that the electric lawn trimmer 100 does not need an external power supply, which is convenient for operation. Of course, in order to save power consumption and prolong the battery life of the battery pack 13, it is necessary to switch the state of the motor assembly 12 so that it can be switched between the startup state and the shutdown state. Specifically, the state of the motor assembly 12 can be switched through the first switch assembly 14, for example, the motor assembly 12 is triggered when the first switch assembly 14 is turned on, the battery pack 13 can supply power to the motor assembly 12, and the motor assembly 12 can be switched to When the first switch assembly 14 is turned off, the motor assembly 12 is turned off, the battery pack 13 stops supplying power, and the motor assembly 12 can be switched to the shutdown state.

As shown in FIGS. 7 and 8 , for the assembly of the battery pack 13 and the battery compartment 111 , the host 1 can also include a first connector 15 , and the battery pack 13 can include a second connector 131 . When one end is inserted into the battery compartment 111, the first connector 15 and the second connector 131 are inserted, and the first connector 15 can also pass through the first switch assembly 14 to the motor assembly 12, so that the first switch Component 14 to control the on-off of the motor component 12. Moreover, due to the plugging of the first connector 15 and the second connector 131 , force can be provided to the battery pack 13 to a certain extent, preventing the battery pack 13 from sliding down from the battery compartment 111 . Wherein, the combination of the first connector 15 and the second connector 131 can include various suitable female connectors and male connectors, such as the first connector 15 can include needle pins, and the second connector 131 may include a contact hole, so that when the battery pack 13 is inserted into the battery compartment 111, the needle-shaped pin and the contact hole can be plugged in synchronously to provide a certain limit force for the battery pack 13 while conducting electricity, and because the battery The pack 13 includes contact holes, so that the space occupied by the battery pack 13 after disassembly can be reduced, and it is convenient to carry, especially when the battery pack 13 can be used as an independent mobile power supply. Of course, in other embodiments, it may also be that the first connector 15 includes a contact hole, and the second connector 131 includes a needle pin, which is not limited in this application.

Of course, in order to better realize the stable installation of the battery pack 13 in the battery compartment 111, as shown in Figs. The battery compartment 111 is provided. For example, in the embodiment provided by the present application, the damping member 16 can be arranged on both sides of the battery compartment 111. When the battery pack 13 is inserted into the battery compartment 111, the side edge of the battery pack 13 can be in contact with the damping element. The component 16 abuts against the battery pack 13 through the damping component 16 , so that the battery pack 13 is detachably assembled in the battery compartment 111 . The damping element 16 can be fixedly connected with the housing 11, or the housing 11 can include an assembly hole, and the damping element 16 can be fixed by interference fit with the assembly hole. Of course, in some other embodiments, the first connector 15 and the second connector 131 may also be in contact, that is, the cooperation between the first connector 15 and the second connector 131 cannot provide a limit for the battery pack 13 body. In the case of force, the battery pack 13 can also be limited by the damping member 16 alone, which can be specifically designed as required, which is not limited in this application.

It can be understood that when the motor assembly 12 is in the off state, that is, there is no external load when the host 1 stops working, the external force on the host 1 is usually only the force when the user moves, and will not cause a great impact on the host 1. Sliding, so that the limiting force provided by the damping member 16, or the limiting force provided when the first connector 15 and the second connector 131 are plugged together, or the limiting force provided by the damping member 16 and the second The limiting force provided by the first connector 15 and the second connector 131 when they are plugged together work together to make the battery pack 13 be firmly arranged in the battery compartment 111 .

And when the motor assembly 12 is switched to the starting state, the cutting tool starts to move to trim green plants, and the load increases, which inevitably causes the main machine 1 to shake. Therefore, in order to avoid a power outage caused by the battery pack 13 falling off due to shaking when the motor assembly 12 is started and the host 1 is working, the host 1 can also include a locking structure, which includes a locked state and an unlocked state. When switching to the starting state, the locking structure is switched to the locking state to lock the battery pack 13 located in the battery compartment 111, and when the motor assembly 12 is switched to the shutdown state, the locking structure is switched to the unlocking state, and the battery The bag 13 is detachably installed in the battery compartment 111 . In this way, on the one hand, the battery pack 13 can be locked when the motor assembly 12 is working to prevent it from falling off; In the bin 111, it is only necessary to provide corresponding force when the user needs to disassemble.

For example, in the embodiment provided by the present application, the locking structure may include a first switch assembly 14, and the first switch assembly 14 may include a first switch body 141 and a trigger button 142, and the first switch body 141 is used to It is used to control the on-off of the motor assembly 12. As shown in Figure 9, the trigger button 142 may include a second limiting portion 1421, the battery pack 13 may include a first limiting portion 132, the housing 11 may include a first mating port 31112 communicating with the battery compartment 111, and the trigger button 142 can be set in the first matching port 31112 , and the first switch main body 141 can be set in the casing 11 . Based on this, when the user triggers the trigger button 142, the trigger button 142 can move toward the first switch body 141 along the first fitting opening 31112 to trigger the first switch body 141, and at the same time, the second limiting portion 1421 can move toward the first switch body 141. The limiting part 132 moves until the first switch main body 141 is triggered to switch the motor assembly 12 to the starting state, and the second limiting part 1421 cooperates with the first limiting part 132 to limit the battery pack 13 . Among them, in order to prevent the battery pack 13 from falling off during the operation of the main unit 1, when the motor assembly 12 is in the starting state, the cooperation between the first limiting part 132 and the second limiting part 1421 should be maintained, so it is necessary to avoid Movement of the trigger button 142 . Therefore, in this embodiment, the trigger button 142 can be set on the user's normal grip area on the host 1, so that when the user presses the trigger button 142, the motor assembly 12 can be maintained in the activated state, and at the same time can make the The first limiting part 132 and the second limiting part 1421 maintain a limiting state.

In the embodiment provided by the present application, as shown in FIGS. 9 and 10 , the first limiting part 132 may include a buckle groove, and the second limiting part 1421 may include a buckle. When the trigger button 142 is pressed, The buckle moves toward the buckle slot and when the motor assembly 12 is switched to the starting state, the buckle is engaged in the buckle slot to limit the position of the battery pack 13 . Alternatively, in other embodiments, the first limiting portion 132 may also include a protruding portion, and the battery pack 13 is limited by the cooperation of the protruding portion and the buckle, and is protruding relative to the first limiting portion 132 Part of the technical solution, in the embodiment provided by the application, the first limiting part 132 of the battery pack 13 is a technical solution of a buckle groove, which can reduce the occupied space of the battery pack 13 and is conducive to the compact structure of the host 1; especially , when the battery pack 13 is used alone as a mobile power source, the battery pack 13 has no extra protruding area, which can be easily carried and stored.

In the embodiment provided in this application, the trigger button 142 includes the second limiting part 1421 as an example for illustration. In fact, in other embodiments, the second limiting part 1421 can also be different from the trigger button 142. other parts, and the second limiting part 1421 is connected with the trigger button 142, and the trigger button 142 moves to make the second switch assembly switch between the locked state and the unlocked state. The locking structure is the first switch component 14. When the first switch component 14 is turned on, the motor component 12 is triggered and the battery pack 13 is locked synchronously, and when the first switch component 14 is turned off, the motor component 12 is turned off and the battery pack is unlocked synchronously. 13 as an example, in fact, in other embodiments, the locking structure can also be independent of other structures of the first switch assembly 14, for example, the locking structure can include a limit rod, the limit rod and the second switch assembly 14 A switch assembly 14 is connected. When the first switch assembly 14 is switched to the conduction state, it can synchronously drive the limit rod to move towards the battery pack 13. When the first switch assembly 14 is triggered, the limit rod is away from the battery pack 13. The outer end surface of the first connector 15 of the host 1 abuts against the limit to limit the falling off of the first connector 15 and the second connector 131 and prevent the battery pack 13 from falling off; or, in some other embodiments, the host 1 can also The transmission assembly is connected to the motor assembly 12, and the transmission assembly is connected to the locking structure. When the motor assembly 12 is triggered, part of the power output by the motor assembly 12 can be transmitted to the tool to drive the tool to move, and the other part of the power can be transmitted through the transmission assembly. To the locking structure, to drive the locking structure to move to the locked state, and when the motor assembly 12 is switched to shutdown and loading, the locking structure can automatically reset to the unlocked state. Of course, the locking structure may also have other structural forms or matching methods, which will not be repeated here.

In each of the above embodiments, the battery compartment 111 can penetrate to the first end of the casing 11, and the battery pack 13 can be inserted into the battery compartment 111 from the first end, so that the first connector 15 and the second connector 131 plugged in, and the side edge of the battery pack 13 is limited by the damping member 16 . In order to prevent the user from acting on the battery pack 13 to make it transition towards the first connector 15, causing displacement or damage to the internal parts of the housing 11, the battery pack 13 can also include a protruding edge 133, when the battery pack 13 passes through the first connector 15 When the end is inserted into the battery compartment 111 and installed in place, the protruding edge 133 can abut against the first end of the housing 11 to remind the user that the current battery pack 13 is installed in place, so as to avoid damage caused by the user's over-installation of the battery pack 13 .

However, due to the insertion of the first connector 15 and the second connector 131 and the limiting effect of the damping member 16 , the user needs to apply a certain force beyond the battery pack 13 to disassemble the battery pack 13 . Therefore, in order to facilitate disassembly by the user, the housing 11 may also include a avoidance gap 113 at the first end, through which the end of the battery pack 13 away from the second connector 131 can be exposed, that is, the side of the battery pack 13 close to the first end A part can be exposed by avoiding the notch 113 , which is convenient for the user to apply force to the exposed part of the battery pack 13 to realize disassembly.

In the above embodiments, the main engine 1 of the electric grass trimmer 100 is described in detail, and the electric grass trimmer 100 will be described in conjunction with the host 1 , the base 3 and the push rod 2 below.

As shown in Figure 11, the base 3 can be assembled with the host 1 to limit the host 1, and the push rod 2 can include a second switch assembly (not shown), which can be used to control the start and stop of the motor assembly 12 . It can be understood that, in the foregoing embodiments, when the push rod 2 and the base 3 are not installed on the electric grass trimmer 100, the user can directly hold the main unit 1 to trim, and at this time, the first switch assembly 14 can be used to control the motor assembly 12. On and off. When the electric grass clipper 100 is equipped with the push rod 2 and the base 3, the user mainly controls the electric grass clipper 100 to trim the work by holding the push rod 2, so in order to avoid accidental touch, when the push rod 2 is assembled on the base 3 , the first switch assembly 14 can be kept disconnected, and at this time, the motor assembly 12 can be started or closed by the second switch assembly, that is, the start and stop of the electric grass trimmer 100 can be controlled by the second switch assembly, and the push rod 2 and When the base 3 is disassembled, the motor assembly 12 can be activated or deactivated through the first switch assembly 14 . Based on this, when the electric lawn trimmer 100 changes from the holding mode to the pushing mode, the first switch assembly 14 can be prevented from accidentally touching the starter motor assembly 12 , causing a safety risk.

Wherein, in the state where the push rod 2 is assembled on the base 3 and the base 3 is assembled with the host 1, the first switch assembly 14 can be maintained in an off state through circuit control, and the second switch assembly can start or close the motor assembly 12; or , in other embodiments, such as the embodiment provided in this application, when the host 1 is assembled on the base 3, the trigger button 142 of the first switch assembly 14 can be locked through the base 3, and the trigger button 142 can be restricted from moving along the first mating port 31112. Moving toward the first switch main body 141 , the first switch assembly 14 can be maintained in the disconnected state mechanically.

Specifically, the base 3 may include a second matching port, and the trigger button 142 may include a recessed groove 1422. When the host 1 and the base 3 are assembled, the trigger button 142 may pass through the second matching port and be disposed in the second matching port. At this time, the recessed groove 1422 of the trigger button 142 can face the edge of the second matching port, and then the base 3 and the host 1 can be pushed to slide relative to each other, so that the edge of the second mating port extends into the recessed groove 1422, so that the second Cooperating with the restrictive effect of the edge of the opening, the trigger button 142 cannot be pressed even if an external force acts on the trigger button 142 , so that the trigger button 142 is locked. Wherein, the surface of the base 3 facing the host 1 can be flat, and the host 1 can be assembled on the surface of the base 3; in another embodiment, the base 3 can include a matching cavity 32, which communicates with the second matching port , the host 1 can be assembled in the fitting cavity 32 , and the host 1 can slide relative to the fitting cavity 32 , so that the edge of the second fitting port extends into the recessed groove 1422 of the trigger button 142 to lock the trigger button 142 . In this embodiment, since the trigger button 142 cannot be pressed, the battery pack 13 cannot be limited by the second limiting portion 1421 on the trigger button 142, especially when the battery compartment 111 of the housing 11 penetrates to the housing 11 When the first end of the electric grass trimmer 100 is in the working process, the battery pack 13 is easy to fall off. Therefore, in order to solve this technical problem, in the embodiment of the present application, when the edge of the second fitting port extends into the recessed groove 1422 of the trigger button 142, the inner wall of the fitting cavity 32 can abut the battery pack 13 close to the casing The surface provided at the first end of 11 can limit the battery pack 13 through the base 3, so as to avoid the sudden power failure of the motor during the working process and stop working.

In this embodiment, it is necessary to push the host 1 and the base 3 to move relative to each other, so that the edge of the second matching opening locks the trigger button 142 . Therefore, in order to avoid the relative movement of the host 1 and the base 3 due to vibration during the working process of the electric grass trimmer 100, causing the edge of the second matching port to fall off from the recessed groove 1422 of the trigger button 142, the housing 11 of the host 1 and the One side of the base 3 may include a first engaging portion, and the other may include a second engaging portion, and when the trigger button 142 is locked, the first engaging portion and the second engaging portion are engaged with each other, thereby The relative movement between the host 1 and the base 3 is limited to ensure safety performance. Wherein, when the edge of the second mating port extends into the recessed groove 1422 of the trigger button 142, the first locking part and the second locking part can be locked in place, so that the main body and the base 3 can be locked without additional operation by the user. In other embodiments, after the edge of the second mating port extends into the recessed groove 1422 of the trigger button 142, the user realizes the snap-fitting of the first snap-fit part and the second snap-fit part. There is no limit to this. Wherein, the first clamping part may include a slot, and the second clamping part may include a hook. Of course, the first clamping part and the second clamping part may also adopt other clamping forms. Limit.
