Fig. 1 is a schematic structural view of an electric grass cutter 100 according to an exemplary embodiment, and fig. 2 is a schematic structural view of a main machine 1 according to an exemplary embodiment. As shown in fig. 1-2, the electric grass cutter 100 may include a main machine 1, a push rod 2, and a base 3, wherein the main machine 1 may be detachably assembled with the base 3, and the base 3 may be connected to the push rod 2, so that a user may hold the push rod 2 to push the electric grass cutter 100 to move forward or in other respective target directions to cut green plants in respective areas. Alternatively, as shown in fig. 2, the user may detach the push rod 2 and the base 3, and hold the host 1 to trim the green plants, and specifically, the height and the position of the green plants to be trimmed may be selected, which is not limited in the present application. In fact, as shown in fig. 2, the host 1 may be configured with a short cutter to comb green plants, in other embodiments, as shown in fig. 3, the host 1 may also be configured with a long cutter to trim lawns or green plants, and the user may select a cutter adapted to the current trimming object according to actual requirements, which is not limited in this application. The following will describe the technical solution of the present application in detail by taking the configuration of the long cutter by the host 1 as an example.
As shown in fig. 3 to 6, the main unit 1 may include a housing 11, a motor assembly 12, a battery pack 13, and a first switch assembly 14. Wherein, the motor component 12 can be assembled in the shell 11, and the motor component 12 can be connected with the cutter, so that the cutter is driven to move by the motor component 12, and the green plants are trimmed. The shell 11 can also comprise a battery compartment 111, and the battery pack 13 is detachably assembled in the battery compartment 111, and can supply power for the motor assembly 12 through the battery pack 13, so that the electric grass cutter 100 does not need an external power supply, and is convenient to operate. Of course, in order to save power consumption and extend the duration 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 on state and the off state. Specifically, the state of the motor assembly 12 may be switched by the first switch assembly 14, for example, the first switch assembly 14 triggers the motor assembly 12 when turned on, the battery pack 13 may supply power to the motor assembly 12, the motor assembly 12 may be switched to a start state, the motor assembly 12 may be turned off when the first switch assembly 14 is turned off, the battery pack 13 stops supplying power, and the motor assembly 12 may be switched to a shutdown state.
As shown in fig. 7 and 8, for the assembly of the battery pack 13 and the battery compartment 111, the host 1 may further include a first connector 15, the battery pack 13 may include a second connector 131, when the battery is inserted into the battery compartment 111 from one end of the housing 11, the first connector 15 and the second connector 131 are plugged, and the first connector 15 may further be connected to the motor assembly 12 through the first switch assembly 14, so that the on/off of the motor assembly 12 may be controlled through the first switch assembly 14. Moreover, due to the plugging of the first connector 15 and the second connector 131, a force can be provided to the battery pack 13 to a certain extent, avoiding the battery pack 13 from slipping out of the battery compartment 111. The combination of the first connector 15 and the second connector 131 may include various female seat connectors and male seat connectors that are adapted, for example, the first connector 15 may include pin-shaped pins, and the second connector 131 may include contact holes, so that when the battery pack 13 is inserted into the battery compartment 111, the pin-shaped pins and the contact holes may be synchronously plugged, and a certain limiting force is provided for the battery pack 13 while electric conduction is achieved. Of course, in other embodiments, the first connector 15 may include a contact hole, and the second connector 131 may include a pin, which is not limited by the present application.
Of course, to better achieve the stable installation of the battery pack 13 in the battery compartment 111, still as shown in fig. 7 and 8, the host 1 may further include a damping member 16, where the damping member 16 may be disposed on the housing 11 and close to the battery compartment 111, for example, in the embodiment provided in the present application, the damping member 16 may be disposed on two sides of the battery compartment 111, and when the battery pack 13 is inserted into the battery compartment 111, the side edge of the battery pack 13 may abut against the damping member 16, and the battery pack 13 is limited by the damping member 16, so that the battery pack 13 is detachably assembled in the battery compartment 111. The damping member 16 may be fixedly connected to the housing 11, or the housing 11 may include an assembly hole, and the damping member 16 may be fixed in an interference fit with the assembly hole. Of course, in still other embodiments, the first connector 15 and the second connector 131 may be in contact connection, that is, in a case where the first connector 15 and the second connector 131 are not matched to provide a limiting force to the battery pack 13, the damping member 16 may be used to limit the battery pack 13 alone, which may be specifically designed according to the requirement, and the present application is not limited thereto.
It will be appreciated that when the motor assembly 12 is in the off state, i.e. the host 1 is not under an external load when it is stopped, the external force applied to the host 1 is usually only the force applied when the user moves, and does not cause great sliding to the host 1, so that the battery pack 13 can be stably disposed in the battery compartment 111 by the combined action of the limiting force provided by the damping member 16, the limiting force provided by the first connector 15 and the second connector 131, or the limiting force provided by the damping member 16 and the limiting force provided by the first connector 15 and the second connector 131.
When the motor assembly 12 is switched to the starting state, the cutter starts to move to trim green plants, the load is increased, and the host machine 1 is inevitably rocked. Therefore, in order to avoid the power failure caused by the falling of the battery pack 13 due to the shaking when the motor assembly 12 is started and the host 1 is operated, the host 1 may further include a locking structure including a locking state and an unlocking state, when the motor assembly 12 is switched 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 pack 13 is detachably installed in the battery compartment 111. Therefore, on one hand, the battery pack 13 can be locked when the motor assembly 12 works to prevent falling, and on the other hand, when the motor assembly 12 is shut down, the battery pack 13 is unlocked, so that the battery pack 13 can be assembled in the battery compartment 111 under a normal condition, and corresponding acting force is provided when a 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, where the first switch body 141 is used to control the on/off of the motor assembly 12. As shown in fig. 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 engagement opening 31112 communicating with the battery compartment 111, the trigger button 142 may be disposed at the first engagement opening 31112, and the first switch body 141 may be disposed within the housing 11. Based on this, when the user activates the trigger button 142, the trigger button 142 can move along the first engaging opening 31112 toward the first switch body 141 to trigger the first switch body 141, and at the same time, the second limiting portion 1421 can move toward the first limiting portion 132 until the first switch body 141 triggers the motor assembly 12 to switch to the activated state, and the second limiting portion 1421 engages with the first limiting portion 132 to limit the battery pack 13. In order to avoid the battery pack 13 falling off during the operation of the host 1, the first limiting portion 132 and the second limiting portion 1421 should be kept engaged with each other when the motor assembly 12 is in the activated state, so that the movement of the trigger button 142 needs to be avoided. Therefore, in this embodiment, the trigger button 142 may be provided in a conventional grip area of the user on the host computer 1, so that the motor assembly 12 may be maintained in the activated state during the user's pressing of the trigger button 142, and at the same time, the first and second limit parts 132 and 1421 may be maintained in the limit state.
In the embodiment provided in the present application, as shown in fig. 9 and 10, the first limiting portion 132 may include a slot, and the second limiting portion 1421 may include a buckle, and when the trigger button 142 is pressed, the buckle moves toward the slot and switches to the activated state of the motor assembly 12, and the buckle is buckled in the slot to limit the battery pack 13. Or 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, so that compared to the technical scheme that the first limiting portion 132 is a protruding portion, in the embodiment provided by the application, the technical scheme that the first limiting portion 132 of the battery pack 13 is a buckle slot can reduce the occupied space of the battery pack 13, which is beneficial to the compact structure of the host 1, and particularly, when the battery pack 13 is used alone as a mobile power supply, the battery pack 13 has no extra protruding area, and can be conveniently carried and stored.
In the embodiment provided by the present application, taking the trigger button 142 including the second limiting portion 1421 as an example, in fact, in other embodiments, the second limiting portion 1421 may be other parts different from the trigger button 142, and the second limiting portion 1421 is connected to the trigger button 142, and the trigger button 142 moves to switch the second switch assembly between the locked state and the unlocked state. Taking the locking structure as 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 synchronously locked, and when the first switch component 14 is turned off, the motor component 12 is closed and the battery pack 13 is synchronously unlocked by taking as an example, in fact, in other embodiments, the locking structure may also be independent of other structures of the first switch component 14, for example, the locking structure may include a limiting rod, which is connected with the first switch component 14, when the first switch component 14 is switched to a conducting state, the limiting rod may be synchronously driven to move towards the battery pack 13, when the first switch component 14 is triggered, the limiting rod abuts against an outer end face of the battery pack 13 away from the first connector 15 of the host 1 to limit the first connector 15 to be disengaged from the second connector 131, so as to prevent the battery pack 13 from being disengaged, or, in still other embodiments, the host 1 may also include a transmission component connected with the motor component 12, which is connected with the locking structure, when the motor component 12 is triggered, a part of the power output by the motor component 12 may be synchronously driven to move towards the battery pack 13, and the cutter component may be automatically driven to a reset state, and the cutter component may be automatically driven to a reset state, and a cutter is locked state may be loaded. However, other structural forms or matching manners of the locking structure may also exist, and are not described in detail herein.
In the above-described embodiments, the battery compartment 111 may penetrate to the first end of the housing 11, and the battery pack 13 may be inserted into the battery compartment 111 from the first end such that the first connector 15 and the second connector 131 are inserted, and the damping member 16 limits the side edges of the battery pack 13. In order to avoid the user acting on the battery pack 13 to move towards the first connector 15 in a transition manner, causing the internal parts of the housing 11 to shift or be damaged, the battery pack 13 may further include a protruding edge 133, and when the battery pack 13 is inserted into the battery compartment 111 through the first end and is mounted in place, the protruding edge 133 may abut against the first end of the housing 11 to prompt the user that the battery pack 13 is currently mounted in place, so as to avoid the user from damaging the battery pack 13 in a transition manner.
Due to the plugging of the first connector 15 and the second connector 131 and the limiting function of the damping member 16, the user needs to apply a certain force to the super battery pack 13 to detach the battery pack 13. Therefore, for convenience of disassembly, the housing 11 may further include an avoidance notch 113 at the first end, and one end of the battery pack 13 facing away from the second connector 131 may be exposed through the avoidance notch 113, that is, a portion of the battery pack 13 near the first end may be exposed through the avoidance notch 113, so that a user may apply an acting force to the exposed portion of the battery pack 13 to achieve disassembly.
In the above embodiment, the main unit 1 of the electric grass cutter 100 is described in detail, and the electric grass cutter 100 will be described below with reference to the main unit 1, the base 3, and the push rod 2.
As shown in fig. 11, the base 3 may be assembled with the host 1 to limit the host 1, and the push rod 2 may include a second switch assembly (not shown) that may be used to control the activation and deactivation of the motor assembly 12. It will be appreciated that in the foregoing embodiment, when the push rod 2 and the base 3 are not mounted on the electric grass cutter 100, the user can directly hold the main machine 1 for trimming, and at this time, the first switch assembly 14 can control the on/off of the motor assembly 12. When the electric grass cutter 100 is provided with the push rod 2 and the base 3, a user mainly controls the electric grass cutter 100 to perform trimming work by holding the push rod 2, so that in order to avoid false touch, when the push rod 2 is assembled on the base 3, the first switch assembly 14 can be kept off, the motor assembly 12 can be started or closed through the second switch assembly, namely, the starting and closing of the electric grass cutter 100 can be controlled through the second switch assembly, and when the push rod 2 and the base 3 are both detached, the motor assembly 12 can be started or closed through the first switch assembly 14. Based on this, it is possible to avoid the first switch assembly 14 from erroneously touching the starter motor assembly 12, causing a safety risk, in the case where the electric grass cutter 100 is shifted from the grip mode to the push mode.
In the state that the push rod 2 is assembled on the base 3 and the base 3 is assembled with the host 1, the first switch component 14 can be kept in an off state through circuit control, and the second switch component can start or close the motor component 12, or in other embodiments, as provided by the application, when the host 1 is assembled on the base 3, the trigger button 142 of the first switch component 14 can be locked by the base 3, and the trigger button 142 is limited to move along the first matching opening 31112 towards the first switch main body 141, so that the first switch component 14 can be kept in the off state mechanically.
Specifically, the base 3 may include a second mating opening, the trigger button 142 may include a recess 1422, when the host 1 and the base 3 are assembled in the second mating opening, the trigger button 142 may be inserted through the second mating opening and disposed in the second mating opening, at this time, the recess 1422 of the trigger button 142 may face the edge of the second mating opening, and then the base 3 and the host 1 may be pushed to slide relatively, so that the edge of the second mating opening stretches into the recess 1422, and therefore, due to the limiting effect of the edge of the second mating opening, the trigger button 142 cannot be pressed even if an external force acts on the trigger button 142, so as to lock the trigger button 142. In another embodiment, the base 3 may include a mating cavity 32, the mating cavity 32 communicates with the second mating opening, the host 1 may be assembled in the mating cavity 32, and the host 1 may slide relative to the mating cavity 32, so that an edge of the second mating opening protrudes into the recess 1422 of the trigger button 142 to lock the trigger button 142.
