Description

Technical Field

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

[0002] Wheelchairs are a common mode of transportation for people with mobility impairments, and stretchers are a common tool for transporting patients. In some special locations, such as hospitals, airports, and subway stations, transport vehicles are needed to move wheelchairs or stretchers and their users. Currently, wheelchair or stretcher transport vehicles typically rely on manual lifting of the wheelchair or stretcher, or the temporary placement of a footboard between the vehicle and the ground to support the wheelchair or stretcher when loading or unloading. This method is inefficient; lifting the wheelchair or stretcher is labor-intensive and time-consuming for staff; and using a footboard requires staff to remove and retract it each time, making it inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a vehicle-mounted wheelchair or stretcher guide locking 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 or stretcher guide locking mechanism includes a wheelchair or stretcher parking area disposed on the vehicle floor, and a guide locking mechanism body disposed below the wheelchair or stretcher parking area and located inside the vehicle floor. The wheelchair or stretcher parking area is provided with fixing claws for fixing the wheels of the wheelchair or stretcher. The guide locking mechanism body includes a guide mechanism, a support guide plate, and a rotary motor. The support guide plate is disposed within the guide mechanism. One side of the support guide plate is threaded onto a fixing screw, and the support guide plate is parallel to the fixing screw. One end of the fixing screw passes through the guide mechanism and connects to the output end of the rotary motor. A rotating shaft is provided on the side of the support guide plate connected to the fixing screw, and the rotating shaft is parallel to the side of the support guide plate. Dampers are provided at both ends of the rotating shaft.

[0006] The rotation of a rotary motor drives a fixed screw, causing the support guide plate to move out or retract. After extending from the guide mechanism, the support guide plate is tilted and rests between the ground and the vehicle floor, allowing wheelchairs or stretchers to enter the transport vehicle. The mechanism operates smoothly and has a strong load-bearing capacity. After the wheelchair or stretcher enters the wheelchair or stretcher parking area on the vehicle floor, the wheels are secured by locking clips to prevent passengers from slipping due to vehicle starts, stops, or bumps, thus avoiding injury or death.

[0007] Preferably, a connecting block is provided on the side where the support guide plate connects to the fixed screw, and a movable nut is fixedly connected to the connecting block. The movable nut is threaded onto the fixed screw. The movable nut moves on the fixed screw, which in turn drives the support guide plate to move through the connecting block, resulting in a simple and stable operation.

[0008] Preferably, the wheelchair or stretcher parking area is provided with a limiting groove for the movement of the wheelchair or stretcher wheels, and a position sensor is provided in the limiting groove; the fixing claw is located at the limiting groove. The position sensor quickly determines whether the wheelchair or stretcher is located in the limiting groove in the wheelchair or stretcher parking area, and then the limiting groove guides the wheelchair or stretcher wheels to quickly and accurately engage with the fixing claw.

[0009] Preferably, the support guide plate is provided with anti-slip texture.

[0010] Preferably, baffles are provided on both sides of the support guide plate that are parallel to the moving direction of the support guide plate.

[0011] Preferably, the guide mechanism has mounting plates that are slidably connected to the supporting guide plate on two opposite sides.

[0012] Compared with the shortcomings and deficiencies of the existing technology, the present invention has the following beneficial effects:

[0013] This invention features a wheelchair or stretcher guide locking mechanism installed in the floor of a transport vehicle. A motor within the mechanism controls an extendable or retractable support guide plate. After extending from the guide mechanism, the support guide plate tilts and rests between the ground and the vehicle floor, facilitating the insertion of the wheelchair or stretcher into the transport vehicle. The wheels of the wheelchair or stretcher are then secured using locking clips. This wheelchair or stretcher guide locking mechanism operates smoothly, has strong load-bearing capacity, and effectively prevents wheelchair or stretcher passengers from slipping due to vehicle starts, stops, or bumps.

[0018] 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.

[0019] The vehicle-mounted wheelchair or stretcher guiding and locking mechanism provided by this utility model is as follows: Figure 1-3 As shown, the vehicle floor 1 of the transport vehicle is provided with a wheelchair or stretcher parking area 2. The wheelchair or stretcher parking area 2 is provided with a limiting groove 13 for the movement of the wheelchair or stretcher wheels. The limiting groove 13 is provided with a position sensor 12. The position sensor 12 can quickly determine whether the wheelchair or stretcher is located in the limiting groove 13 on the wheelchair or stretcher parking area 2. The limiting groove 13 is provided with clamp-shaped fixing claws 11 on both sides. The fixing claws 11 are used to fix the wheels of the wheelchair or stretcher to prevent the wheelchair or stretcher passengers from slipping off due to the start and stop of the vehicle or bumps.

[0020] Below the wheelchair or stretcher parking area 2, there is a guide locking mechanism body located inside the vehicle floor 1. The guide locking mechanism body includes a guide mechanism 3, a support guide plate 4, and a rotary motor 10. The support guide plate 4 is installed inside the guide mechanism 3. A connecting block 5 is installed on one side of the support guide plate 4. A movable nut 8 is fixedly connected to the connecting block 5. The movable nut 8 is threaded onto the fixed screw 9. The support guide plate 4 and the fixed screw 9 are arranged parallel to each other. One end of the fixed screw 9 passes through the guide mechanism 3 and is connected to the output end of the rotary motor 10. The rotary motor 10 drives the fixed screw 9 to rotate, causing the movable nut 8 to move on the fixed screw 9, which in turn drives the support guide plate 4 to move through the connecting block 5. The guide mechanism 3 has mounting plates 14 that are slidably connected to the support guide plate 4 on two opposite sides to provide support for the support guide plate 4 and make its movement more stable. The support guide plate 4 has baffles 15 on both sides parallel to the direction of movement of the support guide plate 4 to prevent wheelchairs or stretchers from slipping off the support guide plate 4 when getting on or off the vehicle. In addition, the support guide plate 4 has anti-slip texture.

[0021] A rotating shaft 6 is provided on the side of the support guide plate 4 that is connected to the connecting block 5, and the rotating shaft 6 is parallel to the side of the support guide plate 4. Dampers 7 are provided at both ends of the rotating shaft 6. Through the cooperation of the dampers 7 and the rotating shaft 6, the front end of the support guide plate 4 is slowly and steadily lowered to the ground.

[0022] 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.
