Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shared wheelchair technology, and in particular to an intelligent shared wheelchair lock. Background Technology
[0002] In the healthcare system, combining sharing methods with the use of medical devices can significantly improve the utilization rate of medical devices and the convenience for patients. A shared wheelchair system mainly consists of three parts: the wheelchair body, the controllable locking mechanism, and the sharing command system, with the locking mechanism being particularly crucial.
[0003] Current smart shared wheelchair locks require the wheelchair to be moved to the correct position before they can be secured. If the wheelchair is tilted or shifted, the lock hole will not align properly, making it difficult to lock.
[0004] Therefore, in view of this situation, there is an urgent need to design and produce an intelligent shared wheelchair lock to meet the needs of actual use. Utility Model Content
[0005] The purpose of this invention is to provide an intelligent shared wheelchair lock to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent shared wheelchair lock, comprising a first lock for fixing an intelligent shared wheelchair, a return spring welded to the side of the first lock, a second lock welded to the end of the return spring away from the first lock, a second fixing plate fixedly connected to the side of the first lock, a fixing frame fixedly connected to the upper side of the second fixing plate, a telescopic rod fixedly connected to the side of the fixing frame away from the second fixing plate, a movable plate fixedly connected to the extended end of the telescopic rod, and a second motor for assisting in fixing the intelligent shared wheelchair mounted on the upper side of the movable plate.
[0007] Preferably, the output end of the second motor is fixedly connected to a threaded shaft, and the upper side of the second latch is fixedly connected to a limiting rod to prevent the second latch from dislodging.
[0008] Preferably, the limiting rod is slidably connected to the first latch, and the side of the movable plate is slidably connected to the side of the fixed frame.
[0009] Preferably, a first connecting member is fixedly connected to the side of the first latch, and a rotating rod is fixedly connected to the side of the first connecting member.
[0010] Preferably, a first fixing plate is sleeved on the side of the rotating rod, and a wheelchair locking post is fixedly connected to the side of the first fixing plate away from the first connecting member.
[0011] Preferably, the side of the wheelchair locking post is provided with a fixing groove that engages with the second fixing plate.
[0012] Preferably, a first motor is mounted on the side of the first fixing plate, and the output end of the first motor is fixedly connected to the rotating rod.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] When this smart shared wheelchair lock is fastened, the first and second locks are used to engage with the wheelchair's armrests. The smart shared wheelchair is fixed by engaging with the armrests. The first and second locks have a large curvature and size, so precise engagement is not required when engaging with the armrests. The smart shared wheelchair can be engaged even if it is tilted.
[0015] The telescopic rod is activated to move the movable plate, which in turn moves the second motor and the threaded shaft, making it easier for the first and second latches to engage with the wheelchair latch posts, thus making the fasteners easier and simpler to lock.
[0016] The second latch and return spring provide protection and cushioning for the smart shared wheelchair, preventing damage caused by over-locking. Attached Figure Description

[0027] To address the issue of difficulty locking shared wheelchairs when they need to be moved to the correct position before being secured, and the wheelchair's tilting or shifting prevents it from aligning with the lock, the following measures are proposed: Figures 1 to 4 The diagram illustrates a smart shared wheelchair locking system, comprising a first locking buckle 6 for securing the smart shared wheelchair. A return spring 9 is welded to the side of the first locking buckle 6. A rubber pad is provided on the side of a limiting rod 7 to provide friction for the movement of the return spring 9 and the second locking buckle 8. The second locking buckle 8 is welded to the end of the return spring 9 away from the first locking buckle 6. A second fixing plate 11 is fixedly connected to the side of the first locking buckle 6. A fixing frame 10 is fixedly connected to the upper side of the second fixing plate 11. A telescopic rod 12 is fixedly connected to the side of the fixing frame 10 away from the second fixing plate 11 for telescopic movement. A movable plate 13 is fixedly connected to the extended end of the rod 12. A slider is provided on the side of the movable plate 13, and a sliding groove is provided on the side of the fixed frame 10 to facilitate sliding connection with the movable plate 13. A second motor 14 for assisting in the fixing of the intelligent shared wheelchair is installed on the upper side of the movable plate 13. A threaded shaft 15 is fixedly connected to the output end of the second motor 14. A hole is provided on the second fixed plate 11 to facilitate the movement of the threaded shaft 15, and the second fixed plate 11 does not contact the threaded shaft 15. A limiting rod 7 to prevent the second lock 8 from dislodging is fixedly connected to the upper side of the second lock 8.
[0028] The limiting rod 7 is slidably connected to the first latch 6. The side of the moving plate 13 is slidably connected to the side of the fixed frame 10. The side of the first latch 6 is fixedly connected to the first connector 5. The side of the first connector 5 is fixedly connected to the rotating rod 4. One end of the rotating rod 4 is fixedly connected to the output end of the first motor 3, and the other end is rotatably connected to the side of the first fixed plate 2.

The side of the fixing groove 16 is provided with a threaded opening to facilitate screwing with the threaded shaft 15. The side of the first fixed plate 2 is equipped with the first motor 3. The output end of the first motor 3 is fixedly connected to the rotating rod 4.
[0029] All structures and instruments are treated with heat-resistant and waterproof materials.
[0030] The first motor 3, the telescopic rod 12, and the second motor 14 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the functions of this application, so they will not be described in detail. They are all controlled by remote control switches. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0031] Working principle
[0032] During use, the smart shared wheelchair lock works by starting the first motor 3, which drives the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the first connecting piece 5 to rotate, which in turn drives the first lock 6 to rotate, and then drives the second lock 8 to rotate. At the same time, the telescopic rod 12 is activated, which moves the moving plate 13. The movement of the moving plate 13 drives the second motor 14 and the threaded shaft 15 to move. Simultaneously, the second motor 14 is activated, which drives the threaded shaft 15 to rotate, and then screws it into the wheelchair lock to secure the smart shared wheelchair.
