[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] This application provides a chair, such as Figure 1 As shown, the seat 2 has a seat shock-absorbing structure, which includes a plurality of shock absorbers 1. The seat 2 includes two opposite first sides 25, and each first side 25 is provided with a plurality of shock absorbers 1. The number of the plurality of shock absorbers 1 is set to be no less than two.

[0059] In a specific embodiment, the two opposite first sides 25 can be arranged along the width direction of the seat 2, or along the length direction of the seat 2. Figure 1 The y direction shown, the length direction of the seat 2 is as follows Figure 1 The x direction is shown.

[0060] In contrast to related art designs that employ one or two shock absorbers on the bottom of a seat, the seat shock-absorbing structure provided in the present embodiment has multiple shock absorbers 1 installed on each first side 25 of the seat 2. Multiple shock absorbers 1 are symmetrically arranged on two opposing first sides 25 of the seat 2. For example, if two shock absorbers 1 are installed on each first side 25 of the seat 2, then four shock absorbers 1 are installed on the opposing first sides 25 of the seat 2. By arranging multiple shock absorbers 1 on each first side 25 of the seat 2, a more balanced force distribution and shock absorption effect can be achieved.

[0061] In some embodiments, the two first sides 25 of the seat 2 are arranged relative to each other along the width direction of the seat 2, so that multiple shock absorbers 1 are arranged on the left and right sides of the seat 2, so that the seat shock-absorbing structure can provide a balanced shock-absorbing effect along the width direction of the seat 2.

[0062] In some embodiments, the plurality of shock absorbers 1 on the two first sides 25 of the seat 2 are symmetrically arranged along the extension direction parallel to the first sides 25 and / or the arrangement direction of the two first sides 25. The extension direction of the two first sides 25 is the same as the length direction of the seat 2, and the arrangement direction of the two first sides 25 is the same as the width direction of the seat 2. The length direction of the seat 2 is as follows: Figure 1 The x direction is shown, and the width direction of the seat 2 is as shown Figure 1 y direction shown.

[0063] When the plurality of shock absorbers 1 are symmetrically arranged along the extension direction of the two first sides 25 and the arrangement direction of the two first sides 25, the plurality of shock absorbers 1 are symmetrically distributed along the length direction and the width direction of the seat 2, that is, the plurality of shock absorbers 1 are uniformly loaded on the length direction and the width direction of the seat 2, and this arrangement can provide more balanced stress and shock absorption effect.

[0064] In some embodiments, each first side 25 of the seat 2 is provided with two shock absorbers 1, that is, two shock absorbers 1 are arranged along the length direction of the seat 2, and two shock absorbers 1 are arranged along the width direction of the seat 2, so that the shock absorbers 1 are uniformly arranged at the four corners of the seat 2, thereby achieving balanced shock absorption effect.

[0065] In some embodiments, the shock absorber 1 includes a magneto-rheological damper or a linear motor. The magneto-rheological damper generates a magnetic field when powered on, and a magneto-rheological fluid is filled in the shell of the magneto-rheological damper. The magneto-rheological fluid changes from a fluid to a viscoelastic solid when passing through the magnetic field. When the magnetic field disappears, the viscoelastic solid changes back to the flowing fluid. By controlling the current to change the magnetic field strength, the yield stress of the fluid can be accurately controlled, thereby controlling the resistance provided by the magneto-rheological damper and achieving intelligent control of the shock absorption effect of the seat.

[0066] The magneto-rheological damper shock absorption seat provided by the embodiments of the present application belongs to a semi-active seat suspension. Compared with the passive seat suspension in the related art, the semi-active seat provided by the embodiments of the present application can change the stiffness or damping of the seat system according to different driving states, thereby reducing the vibration impact on the passenger. Compared with the active seat suspension in the related art, the semi-active seat suspension provided by the embodiments of the present application uses a rigid seat frame movable assembly and a magneto-rheological damping shock absorber, so that even in the case of semi-active control failure, the passive seat control effect can be achieved. The semi-active seat system consumes less energy, has a simple structure, is low in cost, high in reliability, and can achieve vibration control effect close to that of the active seat suspension. For example, the current of the magneto-rheological damper can be changed according to different driving conditions, thereby changing the damping of the magneto-rheological damper, and filtering vibrations of different amplitudes, and achieving shock absorption adjustment of the seat within a certain range.

[0067] In some embodiments provided in the application, Figure 1 and Figure 2 The seat 2 includes a seat frame 5 located at the first side 25, the seat frame 5 includes a first part seat frame 51 and a second part seat frame 52, and the first part seat frame 51 is movably connected to the second part seat frame 52.

The second aspect is that the first part seat frame 51 is connected to the main part of the vehicle seat, and the second part seat frame 52 is connected to the ground of the vehicle. By changing the rigid connection between the seat and the ground of the vehicle to a rigid connection structure that can have a certain amount of floating in the axial direction, both the required floating amount for the installation of the shock absorber 1 is provided, and the strength of the seat is ensured.
