[0028] Reference Figures 1 to 7 This is an embodiment of the present utility model, which provides a wheelchair with a storage function, enabling users to quickly take out or lock the storage box 201c and place their personal belongings under the wheelchair body 100.

[0029] The wheelchair body 100 includes a chair body 101, a fixed seat 102 fixedly installed on the top of the chair body 101, a seat cushion 103 fixedly connected to the outer surface of the fixed seat 102, a lumbar support 104, a backrest 105 and a headrest 106 fixedly connected to the top of the fixed seat 102 in sequence, a rear wheel 107, a front wheel 108 and an armrest 109 respectively provided on both sides of the chair body 101, a fixed frame 110 fixedly connected to the bottom of the chair body 101, a foot pedal 111 fixedly installed on the outer end face of the fixed frame 110, and a battery 112 adapted to be installed on the inner surface of the chair body 101.

[0030] It should be noted that the wheelchair body 100 is 1150mm long, 700mm wide, and 1260mm high. The seat 101 is the main structure of the wheelchair body 100. The fixed seat 102 is used to install the seat cushion 103, lumbar support 104, backrest 105, and headrest 106. The seat cushion 103 is used to provide seat support, while the lumbar support 104, backrest 105, and headrest 106 are used to provide back and head support, respectively. The seat cushion 103, lumbar support 104, backrest 105, and headrest 106 are all made of memory foam. The lumbar support 104 and backrest 105 are 590mm high, and the headrest 106 is 300mm wide. The rear wheel 107 and front wheel 108 provide mobility. The hubs of both the rear wheel 107 and the front wheel 108 are made of aluminum-zinc alloy. The diameter of the rear wheel 107 is 600mm, and the diameter of the front wheel 108 is 250mm. The armrest 109 is made of high-density polyethylene and provides arm support. Above the armrests 109 on both sides are control levers and control buttons for assisting in getting up. The control lever on the right armrest can control the forward movement and steering of the wheelchair body 100. The wheelchair body 100 can be connected to the user's mobile phone to realize intelligent interaction functions, meeting the user's needs for intelligent navigation, route planning, emotional companionship, departure reminders, weather forecasts, etc. The footrest 111 is for the user to place their feet. The battery 112 provides power to the wheelchair body 100. In order to prevent the situation where the battery 112 is dead and the wheelchair cannot move, the rear wheel 107 is designed so that the user can still push the wheelchair body 100 even if the battery 112 is dead.

[0031] The storage mechanism 200 includes a support component 201 disposed at the bottom of the fixed base 102 for storage purposes, and a plug-in component 202 and a locking component 203 used in conjunction with the locking bracket 110 and the support component 201.

[0032] Specifically, the support component 201 includes guide rails 201a fixedly connected to the bottom of both sides of the fixed base 102, connecting posts 201b disposed inside the guide rails 201a, and storage box 201c fixedly connected to the outer surface of the connecting posts 201b.

[0033] It should be noted that the guide rail 201a is used to guide the sliding of the connecting column 201b, the connecting column 201b is used to support the storage box 201c, and the storage box 201c is used to store items.

[0034] Furthermore, the outer surface of the connecting column 201b slides in contact with the inner wall of the guide rail 201a, and the storage box 201c is located inside the fixing frame 110.

[0035] Preferably, the plug-in assembly 202 includes a fixed post 202a fixedly connected to the outer surface of the fixed frame 110, a plug-in rod 202b fixedly connected to the other end of the fixed post 202a, a pressing block 202c fixedly connected to the other end of the plug-in rod 202b, and a slider 202d slidably sleeved on the outer surface of the plug-in rod 202b.

[0036] Among them, the fixed post 202a is used to support the plug-in rod 202b and the pressing block 202c, the pressing block 202c is used to lock or unlock the storage box 201c, and the slider 202d is used to assist the unlocking process.

[0037] It should be noted that the extrusion block 202c and the slider 202d are adjacent to each other on a flat surface, and the other side is an inclined surface.

[0038] Furthermore, the locking assembly 203 includes a fixing sleeve 203a fixedly installed on the outer surface of the storage box 201c, limiting grooves 203b respectively opened on the inner walls of both sides of the fixing sleeve 203a, a spring 203c fixedly installed on the inner wall of the limiting groove 203b, and a limiting block 203d fixedly installed on the other end of the spring 203c.

[0039] Specifically, the outer surface of the limiting block 203d slides in contact with the inner wall of the limiting groove 203b. The side of the limiting block 203d closest to the opening of the fixed sleeve 203a is an inclined surface, and the other side is a flat surface.

[0040] In use, when it is necessary to remove the storage box 201c, the user applies force to push the storage box 201c towards the fixing sleeve 203a. This causes the storage box 201c to move the pressing block 202c deeper into the inner cavity of the fixing sleeve 203a via the fixing post 202a and the insertion rod 202b. Then, the fixing post 202a drives the slider 202d to press the limiting block 203d. Because one side of the limiting block 203d is designed with a slope, it is subjected to the sliding... The pressing block 202c under the pressure of block 202d will slide inward along the inner wall of the limiting groove 203b, allowing the slider 202d to pass smoothly and contact the pressing block 202c, forming a whole. At this time, the storage box 201c is pulled, causing the pressing block 202c to drive the slider 202d to squeeze the limiting block 203d into the limiting groove 203b, thereby releasing the limiting block 203d from the pressing block 202c and thus releasing the locking state of the storage box 201c.

[0041] When it is necessary to lock the storage box 201c, push the storage box 201c back to its original position until it is fully in place. Then, move the plane of the pressing block 202c to a position where it contacts the plane of the limiting block 203d. The limiting block 203d uses its plane portion to hold the pressing block 202c in place, so as to ensure that the storage box 201c is securely locked inside the fixing frame 110.

[0042] In summary, through the cooperation of the various components in the storage mechanism 200, users can quickly take out or lock the storage box 201c with simple operations, making it convenient to carry items with them and manage personal belongings without the help of others. This greatly improves the convenience and efficiency of daily activities, thereby significantly increasing the user's autonomy and independence.
