Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rooftop storage devices, specifically a rooftop wheelchair storage box device. Background Technology
[0002] The rooftop wheelchair storage box is a vehicle-mounted assistive device specifically designed for people with mobility impairments or those who frequently need to carry wheelchairs. Its functions and uses revolve around three core aspects: safe storage, convenient transportation, and space optimization. The rooftop wheelchair storage box forms a closed or semi-closed storage space that can completely accommodate the wheelchair, either fully or folded, preventing the wheelchair from being directly exposed to the external environment during transportation. This reduces the corrosion of metal parts and seat fabrics caused by dust, rain, and ultraviolet rays, extending the lifespan of the wheelchair. It solves problems such as space occupation, equipment wear and tear, and laborious operation during wheelchair transportation. It not only improves the travel convenience of people with mobility impairments but also reduces the transportation burden for family members or service providers, making it an important assistive tool in the field of accessible travel.
[0003] Currently, most rooftop wheelchair storage devices place the wheelchair inside by lifting and flipping it over. To prevent the wheelchair from swaying while driving, a retaining bracket is installed inside the device to enclose the wheelchair. Although the retaining bracket does enclose the wheelchair, there is still space between the bracket and the wheelchair, meaning they are not in complete contact. When the vehicle bumps or brakes suddenly, the wheelchair can still sway, producing abnormal noises and increasing the impact on the roof. This could potentially cause the roof seal to crack and leak. Therefore, we provide a rooftop wheelchair storage device that solves these problems. Utility Model Content

The inner wall of the base 27 is hinged to a first electric push rod 28. The output end of the first electric push rod 28 is hinged to the inner wall of the swing arm 26. The first electric push rod 28 provides power for the swing of the swing frame 6. The swing frame 6 keeps the wheelchair and the support horizontal by swinging. The swing frame 6 receives the power of the first electric push rod 28 through the swing arm 26. The swing arm 26 has a tilt angle, which compensates for the angle difference between the first electric push rod 28 and the swing frame 6.
[0036] A support bracket 29 is connected to one side of the swing frame 6. A second electric push rod 30 is installed on one side of the support bracket 29. The output end of the second electric push rod 30 is connected to a push plate 31. The support bracket 29 provides support force to the second electric push rod 30 to maintain its stability. The second electric push rod 30 is used as a power source to provide power for the push plate 31 to move. To prevent the wheelchair from being unable to detach from the first support plate 12 and the second support plate 15, the second electric push rod 30 drives the push plate 31 to move. The push plate 31 pushes the wheelchair out from inside the first support plate 12 and the second support plate 15, preventing the wheelchair from being unable to move downwards.
[0037] Working principle: In use, first, hook 22 is hung on the wheelchair. Then, the second motor 501 is started. After starting, the second motor 501 drives the storage roller 24 to rotate. The rotation of the storage roller 24 winds and retracts the pull rope 21. Simultaneously, the pull rope 21 winds and retracts, moving the wheelchair upwards. Then, the wheelchair contacts the second guide frame 19. The wheelchair, along with the second guide frame 19, partition 9, and slide rail 8, moves upwards simultaneously. Then, the first support plate 12 and the second support plate 15 of the wheelchair contact, simultaneously compressing the first spring 13 and... The second spring 16 then allows the wheelchair to fully enter the enclosure 10. Simultaneously, the first guide frame 17 and the second guide frame 19 come into contact. The first electric push rod 28 is then activated. After the first electric push rod 28 is activated, it drives the swing frame 6 to rotate upward through the swing arm 26. Subsequently, the swing arm 26 rotates until the support frame 2 is at the same level. The second motor 501 is then activated. After the second motor 501 is activated, it drives the gear 1 503 to rotate. The gear 1 503, supported by the gear 2 504, drives the support frame 2 to rotate. Subsequently, the support frame 2 rotates until the mounting frame 1 is in a vertical position.
