Description

Technical Field

[0001] This utility model relates to the technical field of wheelchair restraints for transportation vehicles, specifically a wheelchair restraint. Background Technology

[0002] To ensure the convenience and safety of people with disabilities during travel, wheelchair restraints are used in transportation modes such as rail transit and ships to secure wheelchairs. Existing wheelchair restraints include... Figure 1 The wheelchair restraint shown uses a dual-axis hinge 100. During operation, the primary axis needs to be flipped to a certain angle first, and then the secondary axis needs to be flipped. At the same time, the cover plate is prone to collide with the outer frame, causing deformation.

[0003] Other examples include Figure 2 The wheelchair restraint shown has a cover plate with an exposed hinge 200 that is rotatably connected to the mounting box. The exposed hinge of this type of wheelchair restraint is not only unsightly, but also susceptible to impact and easy for debris to fall in, affecting its service life. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a wheelchair fixation device that, when installed on a wall, is only visible through the cover plate, concealing the hinges. It is aesthetically pleasing, less susceptible to obstruction by debris, and easy to use.

[0005] The technical solution is as follows: A wheelchair restraint device includes a cover plate, a mounting box, a seat belt assembly, and a seat belt buckle. The cover plate is rotatably mounted on the mounting box via a hinge. The seat belt assembly and seat belt buckle are located inside the mounting box. The hinge includes a first fixing seat, a second fixing seat, a first connecting rod, and a second connecting rod. The first fixing seat and the second fixing seat are respectively fixed to the inner side of the cover plate and the inner wall of the mounting box. The first fixing seat and the second fixing seat are respectively provided with a first sliding track and a second sliding track. The first connecting rod and the second connecting rod are curved. One end of the first connecting rod is rotatably connected to the first fixing seat, and the other end is slidably connected to the second sliding track of the second fixing seat. One end of the second connecting rod is rotatably connected to the second fixing seat, and the other end is slidably connected to the first sliding track of the first fixing seat. The middle portions of the first connecting rod and the middle portions of the second connecting rod are rotatably connected to a hinge shaft.

[0006] Furthermore, the first fixing seat and the second fixing seat are each composed of two fixing blocks arranged opposite to each other.

[0007] Furthermore, the slide rail one / slide rail two is composed of grooves on the opposite surfaces of the two fixed blocks. Sliding shaft one and sliding shaft two are slidably connected in slide rail one and slide rail two respectively. Sliding shaft one is rotatably connected to one end of connecting rod two, and sliding shaft two is rotatably connected to one end of connecting rod one.

[0008] Furthermore, a first fixed shaft and a second fixed shaft are respectively connected to the first fixed base and the second fixed base, and the first connecting rod and the second connecting rod are rotatably connected to the first fixed shaft and the second fixed shaft located between the fixed blocks.

[0009] Furthermore, the wheelchair restraint also includes a locking assembly, which includes a female ball lock located on the inner wall of the mounting box and a male ball lock located on the inner side of the cover plate.

[0010] Furthermore, the wheelchair restraint also includes a locking assembly, which includes a magnetic element one located on the inner wall of the mounting box and a magnetic element two located on the inner side of the cover plate, wherein the magnetic element one and the magnetic element two can attract each other.

[0011] Beneficial effects: By housing the seat belt assembly, seat belt buckle, and hinges within the mounting box, these components are protected from damage caused by collisions or debris entering. Furthermore, the wheelchair restraint is only visible through the panel, resulting in an aesthetically pleasing design. It is suitable for use in rail transit, ships, and other transportation vehicles. Attached Figure Description

[0017] like Figure 3 The wheelchair restraint shown includes a cover plate 1, a mounting box 2, a seat belt assembly 3, and a seat belt buckle 4. The cover plate 1 is rotatably mounted on the mounting box 2 via a hinge 5. The cover plate 1 is provided with a handle 8. The seat belt assembly 3 and the seat belt buckle 4 are located inside the mounting box 2. Figure 4 , Figure 5The hinge 5 includes a first fixed seat 51, a second fixed seat 52, a first connecting rod 53, and a second connecting rod 54. The first fixed seat 51 and the second fixed seat 52 are respectively fixed to the inner side of the cover plate 1 and the inner wall of the mounting box 2, so that the hinge 5 can be located inside the mounting box 2 and avoid being exposed when the cover plate 1 is closed. The first fixed seat 51 and the second fixed seat 52 are respectively provided with a first sliding track 55 and a second sliding track 56. The first connecting rod 53 and the second connecting rod 54 are curved. One end of the first connecting rod 53 is rotatably connected to the first fixed seat 51, and the other end is slidably connected to the second sliding track 56 of the second fixed seat 52. One end of the second connecting rod 54 is rotatably connected to the second fixed seat 52, and the other end is slidably connected to the first sliding track 55 of the first fixed seat 51. The middle part of the first connecting rod 53 and the middle part of the second connecting rod 54 are rotatably connected to the hinge shaft 57.

[0018] Specifically, fixed base 1 51 and fixed base 2 52 are each composed of two oppositely arranged fixed blocks, and slide rail 1 55 / slide rail 2 56 are composed of grooves on the opposite surfaces of the two fixed blocks. Slide shaft 1 551 and slide shaft 2 561 are slidably connected in slide rail 1 55 and slide rail 2 56 respectively. Slide shaft 1 551 is rotatably connected to one end of connecting rod 2 54, and slide shaft 2 561 is rotatably connected to one end of connecting rod 1 53.

[0019] Fixed shaft 1 58 and fixed shaft 2 59 are respectively connected to fixed base 1 51 and fixed base 2 52, and connecting rod 1 53 and connecting rod 2 54 are rotatably connected to fixed shaft 1 58 and fixed shaft 2 59 located between the fixed blocks.

[0020] The wheelchair restraint can be installed on the side wall of the vehicle for easy access. When not in use, the cover 1 of the wheelchair restraint closes onto the mounting box 2, concealing the components inside. When needed, the cover 1 is opened via the recessed handle 8. As the angle between the cover 1 and the mounting box 2 gradually increases, the middle of connecting rod 1 53 and the middle of connecting rod 2 54, as well as one end of the connecting rod and the fixing seat, rotate relative to each other. Simultaneously, the other end of the connecting rod slides relative to the fixing seat. As the cover 1 is further opened, the other end of the connecting rod gradually moves from the outside inward. This combination of rotation and movement allows the hinge 5 to exist only inside the mounting box 2 and the cover 1, while the cover 1 can rotate relative to the mounting box 2. The cover 1 can be rotated 180 degrees according to the dimensions of the relevant components, with reliable rotation and good operability. Finally, after opening the cover 1, the user can pull out the seat belt from the seat belt assembly 3, fasten it to the wheelchair, and then secure the seat belt in the seat belt buckle 4, thus securing the wheelchair.

[0021] In addition, the wheelchair restraint also includes a locking assembly, which includes a female ball lock head 6 located on the inner wall 2 of the mounting box and a male ball lock head 7 located on the inner side of the cover plate 1. The ball lock can prevent the cover plate 1 from being opened at will. Of course, the locking assembly can also be replaced with magnetic attachment 1 and magnetic attachment 2 that can attract each other.

[0022] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
