One end of the electric push rod 10 is fixedly connected to a lock rod 11, and the lock rod 11 cooperates with the lock nose 9. When the lock rod 11 passes through the lock nose 9, the lock seat 4 can be limited.
[0035] In this embodiment, the horizontal sliding assembly includes two telescopic rods 12 respectively fixedly mounted on the inner walls on both sides of the sliding cavity 2, and a return spring 13 is sleeved on each of the two telescopic rods 12. A slider 14 is fixedly connected between the two telescopic rods 12, and the ends of the two return springs 13 that are close to each other are respectively fixedly connected to the two sides of the slider 14, and the other ends of the two return springs 13 are respectively fixedly connected to the inner walls on both sides of the sliding cavity 2.
[0036] In this embodiment, the up and down dragging assembly includes a limit cylinder 15 fixedly mounted on the bottom of the slider 14, a circular plate 16 is slidably connected inside the limit cylinder 15, the bottom end of the circular plate 16 is fixedly connected to a limit column 17, the outer wall of the limit column 17 is slidably connected to the bottom of the limit cylinder 15, the limit column 17 is fixedly connected to the top surface of the lock seat 4, a limit spring 18 is sleeved on the limit column 17, the two ends of the limit spring 18 are respectively fixedly connected to the bottom end of the circular plate 16 and the bottom wall of the limit cylinder 15, and when the circular plate 16 moves downward, the limit spring 18 can be compressed.
[0037] The implementation principle of a self-service wheelchair lock in the embodiment of the present application is as follows: first, the shared wheelchair lock is used in conjunction with the main board and management software to realize functions such as scanning code to unlock, time-based charging, fixed-point return of the vehicle, and online settlement. The lock body 6 of the present application is fixed on the self-service wheelchair. First, when the user needs to return the wheelchair, the wheelchair is pushed under the lock pile 1, and at the same time, the lock seat 4 is dragged to the left or right. The lock seat 4 drives the slider 14 to slide horizontally in the slide hole 3 through the limit column 17 and the limit cylinder 15. When the slider 14 moves, it can drive one of the telescopic rods 12 to retract and compress the reset spring 13, so that the notch of the lock seat 4 is located above the lock body 6. The lock seat 4 can be dragged up or down according to needs. When the lock seat 4 moves downward, the limiting column 17 can be driven to move downward, and the limiting column 17 drives the circular plate 16 to slide vertically in the limiting cylinder 15 and compresses the limiting spring 18. At the same time, the lock seat 4 moves downward, so that the lock body 6 is located in the gap of the lock seat 4. At the same time, the card reader 8 is aligned with the chip 7. The card reader 8 senses the chip 7, starts the electric push rod 10 to drive the lock rod 11 to move, and passes through the lock nose 9 to fix the wheelchair. The user can scan the code with the mobile phone and settle the bill online. This application can make the lock body 6 located in the gap of the lock seat 4 by moving the lock seat 4 left and right and up and down, avoiding the situation where the wheelchair is too heavy and the wheelchair needs to be dragged to adjust the position of the lock body 6. It is convenient to use.
[0038] The entire device is connected to a power supply and a main control button, and is controlled by the main control button. Since the devices matched with the control button are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
