In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a rotating protective device for a passenger vehicle wheelchair area, including an aisle handrail 1, one end of which is provided with an inclined corner, and a positioning kit is installed at one end of the aisle handrail 1. A steering seat 4 is installed inside the positioning kit, and a protective swing arm 401 is provided on the top of the steering seat 4. The protective swing arm 401 is U-shaped in general. A first anti-slip sleeve 402 is installed on the first section of the protective swing arm 401, and a second anti-slip sleeve 403 is installed on the second section of the protective swing arm 401. Both the first anti-slip sleeve 402 and the second anti-slip sleeve 403 are made of nylon material to increase their durability and service life.
[0021] like Figures 3-4As shown, the positioning kit consists of a bottom cover 2 and a mounting cover 3. Both the bottom cover 2 and the mounting cover 3 have mounting grooves at one end that mate with the walkway handrail 1. They are fixedly connected by screws. The steering seat 4 has a steering hole 404 at its center, and symmetrical adjustment arc holes 405 on both sides of the steering hole 404. A threaded hole 201 is provided on the bottom cover 2 corresponding to the adjustment arc hole 405 above the steering hole 404. The mounting cover 3 is connected to the threaded hole 201 by an adapter bolt 301, improving connection stability. A nylon shock absorber sleeve 6 is mounted on the adapter bolt 301, and the nylon shock absorber sleeve 6 slides within the steering seat 4. The adjustment arc hole 405 above the steering hole 404 and the adjustment arc hole 405 below the steering hole 404 are respectively provided with a positioning hole 202 on the bottom cover 2. The bottom cover 2 is also provided with a mounting hole 203 in the center. The mounting cover 3 is connected by a fixing bolt 8 through the mounting hole 203 to ensure the overall stability. Symmetrical nylon shock-absorbing pads 7 are also installed in the positioning hole 202. The nylon shock-absorbing pads 7 are used to reduce the lateral and longitudinal vibration of the steering seat 4. The mounting cover 3 is provided with an adjustment hole. The adjustment hole is provided with an indexing pin 5. One end of the indexing pin 5 is interference-fitted with the positioning hole 202 to ensure the stability of the positioning adjustment.
[0022] The specific usage and function of this embodiment are as follows: When there is no wheelchair, the protective swing arm 401 can be flipped up without affecting passenger movement or occupying the aisle space. The steering seat 4 is spatially inclined, forming an acute angle with the wheelchair baffle, rather than the traditional parallel structure, and forms an acute angle with the protective swing arm 401, rather than the traditional vertical tilting flipping path. The movement and rotation of the protective swing arm 401 are three-dimensional in space, not simply the swing arm plane and the flipping plane being on the same plane. After the swing arm is lowered, the protective swing arm 401 is closer to the aisle side. Due to the outward swing of the protective swing arm 401, the wheelchair area has increased space. The width of the protection is wider, making it more convenient for the use of the wheelchair area. After the protective swing arm 401 is flipped up, it moves towards the wheelchair area along the Y-plane of the vehicle. The width occupied is narrower, making it more convenient for the use of the passenger area.
