Detailed ways:

Referring to FIG. 1 , the handlebar 2 of the present invention includes: a handle portion 21 , a middle rod portion 22 and a lower end portion 23 . The handle part 21 and the lower end part 23 are respectively located at the upper and lower ends of the middle rod part 22, wherein the handle part 21 is connected with the middle rod part 22 through a clutch 24, and the lower end of the middle rod part 22 is hinged with the lower end part 23; A locking member 25 , a return mechanism 26 and a non-return mechanism 27 are installed between the lower ends 23 .

The handle part 21 includes: a horizontal direction bar 211 and a vertical shaft 212 fixedly connected together in a "D" shape, wherein the two ends of the direction bar 211 are provided with a power handle and a brake handle for the human body to hold. Electric connection is formed between the power sources, so that the movement of the car body is controlled by the power handle, and the brake handle is linked with the brake parts of the car body.

A hinge structure is adopted between the middle rod part 22 and the lower end part 23, so that the middle rod part 22 can rotate around the hinge fulcrum. The advantage of this design is that when the user drags the whole car body to run, the handle part 21 can pass The rotation of the middle rod portion 22 reaches an angle suitable for dragging by the user, which is convenient for users of different heights to use. Of course, when the user directly drives the utility model, the handle part 21 and the middle rod part 22 cannot still maintain a rotatable state. At this time, the middle rod part 22 and the lower end part 23 need to be fixed by the locking member 25 so that both A fixed connection is formed between them, and they cannot be rotated relative to each other.

The locking member 25 includes: a locking rod 251, a locking sleeve 252, and a locking hole 253 that can form an insertion fit with the locking rod 251. The locking rod 251 is located in the locking sleeve 252 fixed on the middle rod portion 22, and the locking rod 251 has a buckle part 2511, and the lock sleeve 252 is formed with two buckle grooves 2521, 2522 that cooperate with the buckle part 2511. On the lower end 23 of the lock hole 253, the buckle part 2511 is connected with the lock rod 251 respectively. The cooperation of the two locking slots 2521 and 2522 realizes the insertion or separation of the locking bar 251 and the locking hole 253 . In this way, it can be realized whether the middle rod portion 22 and the lower end 24 are in a fixed connection or in a rotatable state.

When the middle rod part 22 and the lower end part 23 are in a rotatable state, in order to reduce the user's stress and make the rotated middle rod part 22 return in time, the utility model adopts a return mechanism 26 .

Referring to Fig. 3, the return mechanism 26 includes: a return compression spring 261 fixed on the lower end 23 and a roller 262 installed on the middle rod 22; The lower end of the compression spring 261 is fixed on the extension plate 263 , and the upper end thereof presses against the roller 262 . The user pushes down the handle portion 21 forward to drive the whole vehicle to move forward. At this time, the middle rod part 22 will drive the handle part 21 to tilt forward, and at the same time, the roller 262 will press down the upper end surface of the return compression spring 261, so that the return compression spring 261 is compressed. The return compression spring 261 will produce an elastic force like this, pushes up the roller shaft 262, makes it return. In this way, when the user presses down the handle portion 21, the return spring 261 will digest the gravity of the handle portion 21 during the inclination process, and the user only needs to apply a little pressure to keep the handle portion 21 at a certain inclination angle. In addition, when the user releases the handle portion 21 , under the action of the return pressure spring 261 , the middle rod portion 22 returns excessively under the action of inertia, and reversely rotates to the direction of the seat. In order to prevent the handlebar from colliding with the vehicle seat or other parts during the return process, the utility model is provided with a non-return mechanism 27 .

The non-return mechanism 27 includes: a blocking piece 271 fixed on the lower end portion 23 and a driving lever 272 hinged on the middle rod portion 22, the blocking piece 271 has a bent portion 2711, and the driving lever 272 has a The bending portion 2711 forms an interfering bending hook 2721 . When the middle rod part 22 returns to the vertical state under the action of the return mechanism 26, because the bending part 2711 of the driving rod 272 interferes with the bending hook 2721, it is ensured that the middle rod part 22 cannot continue to return excessively, thereby maintaining the vertical position. Straight state. In addition, since the driving rod 271 and the middle rod part 22 in the non-return mechanism 27 are hinged, the driving rod 271 can rotate. Move the lever 271 to make the bending part 2711 rotate to an angle that cannot interfere with the bending hook 2721. At this time, force is applied to the seat, so that the handle part 21 and the middle rod part 22 can be completely stacked on the seat. In this way, the volume of the entire car body can be folded smaller.

In order to keep the bending portion 2711 at an angle capable of interfering with the bending hook 2721 , a tension spring 2722 is provided on the driving lever 272 .

Referring to FIG. 2 , the clutch 24 is a device for controlling whether the handle portion 21 and the middle rod portion 212 are linked. It includes: an insertion end 241, an access end 242, a compression spring 243 and a sleeve 244, wherein the insertion end 241 is fixed at the end of the vertical shaft 212 connecting the handle portion 21 and the middle rod portion 22, and has a square cross section. Insert the shaft 2411, the access end 242 is fixed on the upper end of the middle rod part 22, it has a square hole 2421 corresponding to the insertion shaft 2411, and an outer edge 2422 is formed on the periphery of the square hole 2421, and an outer edge 2422 is formed on the outer edge 2422 Notch groove 2423, the sleeve body 244 is sheathed on the junction of the insertion end 241 and the access end 242 by the vertical shaft 212 downwards, the sleeve body 244 has a bottom cover 2411, and the bottom cover 2441 is sleeved on the middle rod portion 22, And be fixed on the open end of sleeve body 244 bottom surface. A card edge 2442 corresponding to the notch 2423 of the outer edge 2422 extends from the through hole formed in the middle of the bottom cover 2441 , and the compression spring 243 is located between the insertion end 241 and the access end 242 . The clutch 24 that has been matched according to the above structure connects the vertical shaft 212 of the handle part 21 with the middle rod part 22. Through the cooperation between the insertion shaft 2411 and the square hole 2421, there will be no relative rotation between them, so as long as the rotation The handle part 21 can drive the middle rod part 22 and the lower end part 23 connected with the middle rod part 22, thereby driving the front wheel to turn. When folding the vehicle, the handle portion 21 needs to be rotated 180 degrees so that the vehicle body can be folded more tightly. At this time, the sleeve body 244 of the clutch 24 is turned, and the sleeve body drives the bottom cover 2441 to rotate. When the card edge 2442 in the through hole of the bottom cover 2441 rotates to the position of the notch groove 2423, the bottom cover 2441 loses the limitation of the card edge 2442 to it. Under the action of the elastic force of stage clip 242, whole clutch 24 moves upwards, and the insertion shaft 2411 of insertion end 241 leaves square hole 2421. Drive the middle rod part 22 to rotate, so that the handle part 21 can be rotated 180 degrees.

Referring to Fig. 1, the utility model is installed on the front end of the front beam of the electric vehicle frame during use, and the handlebar 2 is linked with the front wheel 4 to drive the rotation of the front wheel 4. Front wheel 4 of the present utility model can adopt single-wheel structure, also can adopt double-wheel structure. The lower end 23 of the handlebar 2 is rotatably mounted on the front end of the front beam of the electric vehicle frame, and a gear is arranged on the lower end 23, and the lower end 23 is connected with the front wheel 4 by a chain 41 to realize the connection between the handlebar 2 and the front wheel. Linkage between the wheels 4 to drive the steering of the front wheels 4.

Of course, the above descriptions are only embodiments of the present utility model, and are not intended to limit the implementation scope of the present utility model. Should be included in the utility model patent scope.
