Description

Technical Field

[0001] This utility model relates to an electric wheelchair, and more particularly to an accessory storage mechanism for a shared electric wheelchair and a shared electric wheelchair. Background Technology

[0002] Shared electric wheelchairs are convenient mobility devices that integrate IoT, smart positioning, and mobile payment technologies. Designed specifically for people with mobility impairments, they are commonly found in public places such as hospitals, scenic spots, and shopping malls. Users can quickly rent and return wheelchairs by scanning a QR code with their mobile phones, requiring no human intervention and greatly improving efficiency. These wheelchairs not only feature electric power assistance to reduce the user's physical burden but also are equipped with a smart locking and charging station system to ensure device security, theft prevention, and timely charging.

[0003] The charging systems for shared electric wheelchairs generally adopt an external design, meaning the charging interface or charging station is directly exposed in the public environment. While this structure facilitates quick charging for users, it also presents significant reliability challenges. Because the devices are often placed in densely populated outdoor or semi-outdoor locations, the charging interface is inevitably exposed to wind, sun, rain, snow, and physical impacts, making it highly susceptible to corrosion, deformation, or internal wiring failure. Furthermore, human factors in the public environment, such as unintentional bumps, pulling, or even malicious damage, significantly increase the risk of damage to the charging equipment. Once the charging device malfunctions, not only will the wheelchair be unable to recharge and be taken out of service, resulting in idle and wasted operational resources, but it will also exacerbate the supply-demand imbalance during peak hours, directly impacting users with urgent travel needs. Therefore, improving the structural strength and environmental tolerance of external charging equipment to ensure its stable operation in complex public environments has become a critical issue that urgently needs to be addressed in the development of shared electric wheelchair technology.

[0008] In one embodiment, armrests are fixedly installed on the upper part of the electric wheelchair body.

[0009] In one embodiment, the electric wheelchair body also includes a handle that is detachably fixed to one end of the armrest via a snap-fit ​​structure.

[0010] In one embodiment, a control handle is fixedly mounted on one end of the handle.

[0011] In one embodiment, a mounting screw hole is provided on the upper part of the rear surface of the storage shell, and an arc-shaped clamping plate is fixedly installed on the lower part of the rear surface of the storage shell.

[0012] In one embodiment, two sets of mounting screw holes are provided, and the storage shell is fixedly installed on one side of the armrest of the electric wheelchair body through the two sets of mounting screw holes and the arc-shaped retaining plate.

[0013] In one embodiment, a protective cover is hinged to one side surface of the storage shell, a buckle is fixedly installed on the upper surface of the protective cover, and a locking groove is fixedly installed on the upper side of one side of the storage shell.

[0014] In one embodiment, a fixing block is fixedly installed on the inner surface of the storage shell, a sliding groove is provided on one side of the fixing block, a sliding rod is fixedly installed inside the sliding groove, and sliding blocks are slidably installed at both the upper and lower ends of the surface of the sliding rod, and a retaining ring is fixedly installed on one side surface of the sliding block.

[0015] In one embodiment, a spring structure is installed between the two sets of sliding blocks.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] (1) By setting up a storage box assembly, the charging device is placed in the space below the first partition when using the accessory storage mechanism. The charging wires at both ends of the charging device are connected to the shared electric wheelchair through the wire groove. At the same time, the storage shell is protected by a protective cover to completely isolate it from the external environment.

One end of the charging device 210 is electrically connected to the electric wheelchair body 1 through a charging wire 211. A wire groove 207 is provided on one side of the storage shell 201.

[0029] The upper part of the electric wheelchair body is fixedly installed with an armrest 101, and the electric wheelchair body also includes a handle 102 that is detachably fixed to one end of the armrest 101 by means of a snap-fit ​​structure.

[0030] A control handle 103 is fixedly installed at one end of the handle 102.

[0031] The upper part of the rear surface of the storage shell 201 is provided with mounting screw holes 202, and the lower part of the rear surface of the storage shell 201 is fixedly installed with an arc-shaped card plate 203.

[0032] Two sets of mounting screw holes 202 are provided. The storage shell 201 is fixedly installed on one side of the armrest 101 of the electric wheelchair body 1 through the two sets of mounting screw holes 202 and the arc-shaped clip plate 203.

[0033] During use, the storage shell 201 is first securely fixed to one side of the armrest 101 of the electric wheelchair body 1 by cooperating with the two sets of mounting screw holes 202 and the arc-shaped clamping plate 203. Then, the charging device 210 is placed in the sealed space below the first partition 208. The charging wire 211 at one end of the charging device 210 passes through the wire groove 207 on the side wall of the storage shell 201 to establish an electrical connection with the electric wheelchair body 1, providing a stable power supply to the wheelchair. At the same time, the handle 102 and control handle 103 on the armrest 101 are detachable parts, ready for subsequent transportation and storage.

[0034] Example 2

[0035] Reference Figures 3-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the buckling mechanism 3 includes a second partition 209 fixedly installed on the inner surface of the storage shell 201, and a retaining ring 305 is movably installed inside the second partition 209.

[0036] A protective cover 204 is hinged to one side surface of the storage shell 201. A latch 206 is fixedly installed on the upper part of the surface of the protective cover 204, and a locking groove 205 is fixedly installed on the upper part of one side of the storage shell 201.

[0037] A fixing block 301 is fixedly installed on the inner surface of the storage shell 201. A sliding groove 302 is provided on one side of the fixing block 301. A sliding rod 303 is fixedly installed inside the sliding groove 302. Sliding blocks 304 are slidably installed at both the upper and lower ends of the surface of the sliding rod 303. A retaining ring 305 is fixedly installed on one side surface of the sliding block 304.

[0038] A spring structure 306 is installed between the two sets of sliding blocks 304.

[0039] During use, when the wheelchair needs to be transported, the handle 102 and control handle 103 can be removed from the armrest 101 and inserted into the inside of the retaining ring 305. At this time, the spring structure 306 will press the sliding blocks 304 on both sides towards the center. The sliding blocks 304 move towards the center along the sliding rod 303, causing the retaining ring 305 to apply a continuous clamping force to the handle 102 and control handle 103, thereby effectively fixing them. When the wheelchair is put into use, the user can open the hinged protective cover 204 and insert stick-shaped items such as umbrellas into the retaining ring 305 for temporary storage. After use, close the protective cover 204 so that the latch 206 and the locking groove 205 lock each other to ensure the safety of the storage box assembly.

[0040] The remaining structure is the same as that in Example 1.

[0041] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the storage shell 201 is securely fixed to one side of the armrest 101 of the electric wheelchair body 1 through the tight fit of two sets of mounting screw holes 202 and arc-shaped clamping plate 203. Then, the charging device 210 is placed in the dedicated space below the first partition 208, and its charging wire 211 passes through the pre-set wire groove 207 on the side wall of the storage shell 201 to establish a reliable electrical connection with the electric wheelchair body 1, providing continuous power to the wheelchair. In daily use, the user can open the hinged protective cover 204 at any time and use the snap ring 305 in the snap-fit ​​mechanism 3 to temporarily store umbrellas or other rod-shaped items. At this time, the spring structure 306 will automatically press the sliding blocks 304 on both sides towards the middle. The sliding blocks 304 move smoothly along the sliding rod 303, driving the snap ring 305 to apply an appropriate clamping force to the items to ensure that they will not slip. When bulk transportation or warehousing is required, the detachable handle 102 and its end control lever 103 on the upper armrest 101 of the wheelchair can be removed and inserted into the inside of the retaining ring 305. The spring structure 306 will respond immediately, driving the retaining ring 305 to retract towards the center through the sliding block 304, applying strong squeezing force to the removed parts and firmly fixing them, thereby effectively avoiding damage caused by bumps or collisions during transportation. After use, the protective cover 204 is closed, so that the latch 206 on its surface precisely engages with the locking groove 205 on the storage shell 201, forming a closed and safe protective space. This not only prevents the internal charging equipment 210 from being corroded by the external environment, but also ensures the safety of the stored items. The entire process achieves full-cycle functional coverage from installation, daily use, transportation protection to safe storage.

[0042] In addition, the storage shell in the above embodiments can also be used to store other electric wheelchair accessories such as locks.
