[0002] Electric tricycles are simple to maintain, easy to repair, inexpensive and easy to drive. In China, closed electric tricycles are widely used to pick up and drop off children to and from school.

[0003] The existing closed electric tricycles have doors that need to be opened with a key from the outside, but can be opened from the inside by simply pressing the lock body (the car has a self-locking function, while the electric tricycle's door is a mechanical lock that can be opened from the inside, and the locking function is not good). When picking up children, since children are lively and active by nature, they are likely to open the door while the electric tricycle is in motion, which poses a safety hazard to the children and when the door is open, other drivers are likely to collide with the door, which also poses a safety hazard to passers-by. Therefore, a technical measure is proposed to solve the problem that the electric tricycle door has a poor locking function, children are likely to open the door while the electric tricycle is in motion, which poses a safety hazard to the children and when the door is open, other drivers are likely to collide with the door, which also poses a safety hazard to passers-by.

After the installation is completed, after the child gets on the vehicle, the device is used to lock the door, and the fixing component 2 is used to release the limit on the connecting block 8. At this time, driven by the rebound of the first spring 11 (under normal conditions, the first spring 11 is in a compressed state), the push plate 7 is pulled to move horizontally toward the fixing block 5. The push plate 7 moves horizontally, driving the connecting block 8 and the insertion rod 4 to move horizontally. The insertion rod 4 moves horizontally and enters the limiting hole 13. At this time, the locking of the door is completed. The connecting block 8 moves horizontally, driving the horizontal plate 6. When the insertion rod 4 is inserted into the limiting hole 13, the insertion hole 9 of the horizontal plate 6 moves to the bottom of the fixing component 2. At this time, the fixing component 2 fixes the horizontal plate 6 to complete the fixing of the door in the locked state.

[0026] Reference Figure 1 , Figure 2 , Figure 5As shown, the fixing assembly 2 includes a tube body 201, which is fixedly mounted on the upper surface of the mounting block 1, and a squeezing plate 205 is slidably engaged inside the tube body 201. A lifting rod 203 is connected to the center of the upper surface of the squeezing plate 205. The lifting rod 203 is slidably connected to the tube body 201, and the upper end of the lifting rod 203 is connected to the lifting plate 202. A second spring 204 is provided on the outer sleeve of the lifting rod 203. The upper end of the second spring 204 is fixedly mounted inside the tube body 201, and the lower end of the second spring 204 is fixedly mounted on the upper surface of the squeezing plate 205. A limiting rod 206 is connected to the lower surface of the squeezing plate 205, and the limiting rod 206 is connected to the jack 9 slides and engages, pulling the lifting plate 202 upward, the lifting plate 202 moves upward and drives the lifting rod 203 to move upward, the lifting rod 203 moves upward and drives the extrusion plate 205 to move upward, the extrusion plate 205 moves upward to compress the second spring 204, the extrusion plate 205 moves upward and drives the limiting rod 206 to disengage from the socket 9 inside the connecting block 8, when the insertion rod 4 is inserted into the limiting hole 13, the socket 9 of the cross plate 6 moves to the bottom of the limiting rod 206, at this time release the lifting plate 202, under the rebound action of the second spring 204, drive the limiting rod 206 to insert into the socket 9 of the cross plate 6, complete the fixing of the door locking state.

[0027] Working principle: First, install the device (for example, install it on a single-door electric tricycle), where the fixing block 5 is installed inside the tricycle near the rear of the vehicle body, and the mounting block 1 is installed on the door (the door is usually in the driver's seat, that is, the mounting block 1 is away from children);

[0028] After the installation is completed, after the child gets on the car, the device is used to lock the door. The specific method is to use the fixing component 2 to release the limit on the connecting block 8, pull the lifting plate 202 upward, the lifting plate 202 moves upward to drive the lifting rod 203 to move upward, the lifting rod 203 moves upward to drive the squeezing plate 205 to move upward, the squeezing plate 205 moves upward to compress the second spring 204, the squeezing plate 205 moves upward to drive the limiting rod 206 to disengage from the socket 9 inside the connecting block 8, and the limit on the connecting block 8 is released. At this time, driven by the rebound of the first spring 11 (under normal conditions, the first spring 11 is in a compressed state), the push plate 7 is pulled to move horizontally in the direction of the fixing block 5, and the push plate 7 moves horizontally to drive the connecting block 8 and the insertion rod 4 to move horizontally. Move, the insertion rod 4 moves horizontally into the limiting hole 13, and the door is locked at this time. The horizontal movement of the connecting block 8 drives the horizontal movement of the cross plate 6. When the insertion rod 4 is stuck in the limiting hole 13, the insertion hole 9 of the cross plate 6 moves to be just below the limiting rod 206. At this time, the lifting plate 202 is released, and the limiting rod 206 is driven to insert into the insertion hole 9 of the cross plate 6 under the rebound action of the second spring 204, completing the fixing of the door locking state. Through the setting of the fixing component 2, it is convenient to fix the door locking state to prevent children from pushing the insertion rod 4 and releasing the door lock. At this time, the fixing component 2 is close to the driver, and the door cannot be opened without the fixing component 2. There is no safety hazard of children falling out of the car, and it will not cause safety hazards to other drivers.
