[0002] A wheelchair is an assistive device that provides mobility and independence for people with limited mobility. It is primarily used by patients with temporary or long-term walking impairments, the elderly, and others to assist with daily activities. Wheelchairs are designed for comfort, functionality, and safety, making them suitable for use in a variety of settings, including home, hospital, and outdoor environments. However, purchasing a new wheelchair is currently a costly option for those with temporary walking impairments.

[0003] In existing technology, the number of wheelchairs provided by hospitals is very limited, and some places do not provide wheelchairs for patients' temporary use. Therefore, it is difficult for patients to find a suitable wheelchair for walking assistance when they need it. Based on this situation, the concept of shared wheelchairs has been proposed in existing technology. By arranging shared wheelchairs, patients with temporary mobility difficulties can scan a code to pay the rental fee and unlock the shared wheelchair for use when they need it. After use, they can return the shared wheelchair.

[0004] Therefore, how to lock the shared wheelchair when it is arranged, unlock it after the user scans the code to pay the rental fee, lock it when the user returns the shared wheelchair, and facilitate temporary storage or transportation of the shared wheelchair, etc., are technical problems that need to be solved. Utility Model Content

[0005] In response to the technical problem of how to lock and unlock a shared wheelchair raised in the background technology, the utility model achieves the beneficial effects of convenient locking, unlocking, temporary storage and transportation of the shared wheelchair by installing a locking device on the shared wheelchair storage rack.

[0006] To achieve the above purpose, the present invention provides the following technical solution 1:

[0014] The electromagnet is arranged at the bottom end of the ferromagnetic adjustment block.

[0015] Through the above technical solution, the storage rack in the technical solution of this patent has two parts: a body locking device and a protective device. Among them, the body locking device is used to lock and unlock the shared wheelchair. The working principle of unlocking is that when the user scans the QR code, the external controller controls the electromagnet to work. After the electromagnet works, it has magnetism and generates attraction to the ferromagnetic adjustment block. The attraction drives the lock tongue downward, so that the insert can be pulled out of the plug-in port, achieving the unlocking effect. When locking is required, the insert is inserted into the plug-in port. Under the push of the lock buckle, the lock tongue is pressed down, and the top of the lock tongue eventually extends into the limit opening of the lock tongue, achieving the locking effect. During the locking process, if the lock tongue cannot be pressed down under the push of the lock buckle and it is difficult to lock, you can scan the code and click to return the shared wheelchair to control the electromagnet to work. After the electromagnet works, it has magnetism and generates attraction to the ferromagnetic adjustment block. The attraction drives the lock tongue downward, thereby ensuring a smooth locking process.

[0016] The protective device is used to protect the body locking device. This is because after the wheelchair is deployed, the wheels of the wheelchair may roll and cause damage to the body locking device. Therefore, the protective device is used to limit the position of the wheels. The protective device in the present utility model is configured as a manual type. The manually driven push rod drives the arc-shaped limit rod to slide within the arc-shaped hollow tube, thereby sealing the unsealed portion of the arc-shaped hollow tube.
