Detailed Description
The application will be further illustrated with reference to specific examples. It is to be understood that these examples are illustrative of the present application and are not intended to limit the scope of the present application. Furthermore, it should be understood that various changes and modifications can be made by one skilled in the art after reading the teachings of the present application, and such equivalents are intended to fall within the scope of the application as defined in the appended claims.
The embodiment of the application relates to an asymmetric damping structure for a headrest, which comprises a main board 1 and side wings 2, wherein the side wings 2 are symmetrically and rotatably arranged on two sides of the main board 1, a damping seat 6 is arranged on the lower part of the rear end face of the side wings 2, a damping column 7 is arranged on the damping seat 6, one end of the damping column 7 extends to the rear side face of the main board 1, the other end of the damping column is fixed on the damping seat 6, a damping block 8 fixed on the main board 1 is arranged above the end part of the extending end of the damping column 7, a notch 9 is formed in the lower part of the damping block 8, a first cambered surface 11 and a second cambered surface 10 are arranged at the lower end of the damping block 8, and the first cambered surface 11 and the second cambered surface 10 correspond to the extending end of the damping column 7.
The area of the first cambered surface 11 is smaller than that of the second cambered surface 10.
The first cambered surface 11 and the second cambered surface 10 both adopt cambered surface structures with concave middle parts.
The two sides of the main board 1 are respectively provided with an inclined surface structure with the lower part inclined inwards, and the projection of the damping column 7 is mutually perpendicular to the projection of the inclined surface structure.
The middle parts of two sides of the main board 1 are provided with rotating shaft sleeve structures 3 protruding towards the side wings 2, rotating shafts 4 parallel to the inclined plane structures are arranged in the rotating shaft sleeve structures 3, the side wings 2 are close to one side of the main board 1 and are provided with hollow leakage parts matched with the rotating shaft sleeve structures 3, the upper ends and the lower ends of the hollow leakage parts are respectively provided with connecting ribs 5 parallel to damping columns 7, one ends of the connecting ribs 5 are located on the rear end faces of the side wings 2, and the other ends of the connecting ribs protrude towards the main board 1 and are connected with one ends of the rotating shafts 4.
The front end face of the damping block 8 is provided with a mounting hole 12 for connection.
Examples
Firstly, it is required to determine that the turnover type headrest has two states, one is that the side wing 2 is turned up, the other is that the side wing is turned down, the two states are different, the force born by the side wing 2 in the using process is also different, the upper part of the headrest adopts a surrounding structure, when a passenger uses, the force born by the headrest is smaller, and when the side wing 2 of the headrest is turned down, the headrest main board 1 is in a forward protruding shape, and when the passenger uses, the force born by the headrest is larger.
In order to enable the damping force generated by two different using states of the folding headrest to change, a damping block 8 with two different cambered surfaces is designed, when the headrest in the technical content is used for turning up, the side wings 2 are turned up, at the moment, the damping column 7 can be in contact with the first cambered surface 11, the first cambered surface 11 part of the damping block 8 deforms to generate a damping force, and the headrest side wings 2 are kept in the upturned state while the headrest side wings 2 are prevented from being restored.
When the side wing 2 is folded downwards, the damping column 7 is contacted with the second cambered surface 10, the second cambered surface 10 part of the damping block 8 deforms to generate a damping force, and the damping force generated when the side wing 2 is folded downwards is larger than the force generated when the side wing is turned upwards because the area of the second cambered surface 10 is larger than that of the first cambered surface 11 and the deformation amount of the second cambered surface 10 is larger than that of the first cambered surface 11.
The use of the asymmetric damping block 8 can greatly facilitate the operation of the headrest, so that the operation is more humanized, the comfort level of passengers in use is improved, and the production cost is greatly reduced because the damping block 8 is used for replacing the original asymmetric hinge.
