Description

Technical Field

[0001] This utility model belongs to the field of transportation tool technology, and in particular relates to a vehicle-mounted wheelchair rotation mechanism. Background Technology

[0002] Wheelchair transport vehicles are tools for quickly transporting wheelchair passengers. After the wheelchair is placed on the transport vehicle, in order to reduce the discomfort of the wheelchair passenger by aligning the passenger's sitting direction with the direction the transport vehicle is traveling, the wheelchair needs to be rotated to adjust its direction. This is usually done manually, which is not only inconvenient to operate but also time-consuming. This is especially true for wheelchair transport vehicles used in medical settings, as it can affect the efficiency of diagnosis and treatment for wheelchair patients. Utility Model Content

[0003] The purpose of this utility model is to provide a vehicle-mounted wheelchair rotation mechanism, which aims to solve the problems existing in the prior art mentioned above.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vehicle-mounted wheelchair rotating mechanism includes a wheelchair parking turntable mounted on the vehicle floor and a rotating assembly mounted below the vehicle floor. The wheelchair parking turntable is equipped with fixing claws for securing wheelchair wheels, and multiple sets of omnidirectional wheels are provided at the bottom of the wheelchair parking turntable. A circular groove for accommodating the wheelchair parking turntable is provided on the vehicle floor. The rotating assembly includes a rotating shaft, a coupling, and a rotary motor. The upper end of the rotating shaft is connected to the bottom of the wheelchair parking turntable, and the lower end of the rotating shaft is connected to the output end of the rotary motor via the coupling.

[0006] After the wheelchair is pushed onto the transfer vehicle via the wheelchair loading / unloading guide, it is secured by locking claws. The rotating component controls the wheelchair parking turntable to rotate at a certain angle, so that the seating direction of the wheelchair passenger is the same as the direction of travel of the transfer vehicle, reducing discomfort during the vehicle's journey. After the vehicle arrives at its destination, the rotating component controls the wheelchair parking turntable to rotate at a certain angle, so that the seating direction of the wheelchair passenger faces the wheelchair loading / unloading guide, making it easier for the wheelchair passenger to disembark.

[0007] Preferably, the wheelchair parking area is provided with a limiting groove for the wheelchair wheels to move back and forth, and the fixing claw is located at the limiting groove, so that the wheelchair wheels can be quickly and accurately locked into the fixing claw by the guidance of the limiting groove.

[0008] Preferably, the limiting groove is equipped with a position sensor, which can quickly determine whether the wheelchair is located in the limiting groove in the wheelchair parking area.

[0009] Preferably, the circular groove is provided with an annular groove for accommodating the caster wheel.

[0010] Preferably, the rotary motor is mounted on the lifting mechanism, which controls the rotating component and the wheelchair parking turntable to rise, facilitating the inspection and replacement of the casters at the bottom of the wheelchair parking turntable.

[0011] Compared with the shortcomings and deficiencies of the existing technology, the present invention has the following beneficial effects:

[0012] This invention incorporates a wheelchair rotation mechanism within the floor of a transport vehicle. By rotating the wheelchair parking turntable, the seating direction of wheelchair passengers pushed into the transport vehicle aligns with the vehicle's direction of travel. When disembarking, the turntable can also be rotated to align the wheelchair passenger's seating direction with the wheelchair access guide, facilitating disembarkation. This invention features a simple structure and facilitates easy reversal of wheelchair direction when boarding or alighting from the transport vehicle. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of a vehicle-mounted wheelchair rotation mechanism provided in an embodiment of this utility model.

[0014] Figure 2 This is a top view of the turntable provided in an embodiment of the present invention.

[0015] In the diagram: 1. Vehicle floor; 2. Wheelchair parking turntable; 3. Fixing claw; 4. Rotating shaft; 5. Coupling; 6. Rotary motor; 7. Casters; 8. Limiting groove; 9. Position sensor; 10. Lifting mechanism. Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] The vehicle-mounted wheelchair rotating mechanism provided by this utility model is as follows: Figure 1-2As shown, the floor 1 of the transport vehicle has a circular groove, in which a disc-shaped wheelchair parking turntable 2 is placed flat. Multiple sets of casters 7 are located at the bottom of the turntable 2, arranged on the same ring centered on the turntable 2. An annular groove on the circular groove accommodates the casters 7. When the turntable 2 rotates, the casters 7 roll within the annular groove. The turntable 2 has fixing claws 3 for securing the wheelchair wheels and limiting grooves 8 for allowing the wheelchair wheels to move forward and backward. Clamping claws 3 with a pincer-like structure are located on both sides of the limiting grooves 8 to secure the wheelchair wheels and prevent the wheelchair from moving within the vehicle during transport, thus preventing safety hazards. A position sensor 9 is installed on the limiting grooves 8 to quickly determine whether the wheelchair is positioned within the limiting grooves 8 on the turntable 2.

[0018] A rotating assembly is located inside the vehicle floor 1 below the wheelchair parking turntable 2. This assembly includes a rotating shaft 4, a coupling 5, and a rotary motor 6. The upper end of the rotating shaft 4 is connected to the bottom of the wheelchair parking turntable 2, and the lower end of the rotating shaft 4 is connected to the output end of the rotary motor 6 via the coupling 5. The rotary motor 6 drives the wheelchair parking turntable 2 to rotate via the rotation of the rotating shaft 4, thereby controlling the seating direction of the wheelchair passenger on the turntable 2. Furthermore, a lifting mechanism 10 can be installed inside the vehicle floor 1. The rotary motor 6 is mounted on the lifting mechanism 10, which controls the rotating assembly and the wheelchair parking turntable 2 to rise, facilitating the inspection and replacement of the casters 7 at the bottom of the wheelchair parking turntable 2.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
