[0036] The embodiments of the present application are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application are described in detail below.

[0037] The angle adjusting mechanism 100 according to the embodiments of the present application is described below with reference to Figures 1-7 The angle adjusting mechanism 100 according to the embodiments of the present application can improve the smoothness and stability of the seat during the adjustment of the inclination angle, and has higher structural strength and better interchangeability with the basic configuration.

[0038] In combination with Figures 1-7As shown, the angle adjusting mechanism 100 according to the first aspect of the present application comprises a base support 1, a mounting bracket 2, a cushion edge plate 3, a driving assembly 4, a first linkage 5 and a second linkage 6. Among them, the base support 1 is mainly used as a structural carrier of force bearing, the mounting bracket 2 can provide an installation carrier for related mechanisms, the cushion edge plate 3 is connected with the seat body to form a whole, the driving assembly 4 can provide driving force and transmit the driving force to the required related structure, and the first linkage 5 and the second linkage 6 can link different parts to transmit movement and force at the same time.

[0039] Specifically, the mounting bracket 2 is fixed at the rear end of the base support 1, the rear end of the cushion edge plate 3 is rotatably connected to the mounting bracket 2, the driving assembly 4 is connected to the base support 1, one end of the first linkage 5 is rotatably connected to the front end of the cushion edge plate 3, the first end 61 of the second linkage 6 is rotatably connected to the front end of the base support 1, the second end 62 of the second linkage 6 is rotatably connected to the driving assembly 4, and the third end 63 of the second linkage 6 is rotatably connected to the other end of the first linkage 5; wherein the driving assembly 4 selectively drives the second linkage 6 to rotate around the first end 61, so as to drive the cushion edge plate 3 to rotate through the first linkage 5. For example, the angle adjusting mechanism 100 in the case is suitable for front-row seats, middle-row and rear-row independent seats, and middle-row and rear-row seats with long slide rails, but is not limited thereto.

[0040] In detail, as shown in the drawings, Figure 4 from front to back, when the driving assembly 4 drives the second end 62 of the second linkage 6 to rotate clockwise backward, the second end 62 of the second linkage 6 rotates upward around the first end 61, and the third end 63 also rotates clockwise upward around the first end 61 accordingly, the third end 63 drives the first linkage 5 to rotate clockwise upward, the first linkage 5 drives the front end of the cushion edge plate 3 to rotate clockwise, and the first linkage 5 drives the front end of the cushion edge plate 3 to rotate clockwise upward relative to the mounting bracket 2, so that the cushion edge plate 3 realizes backward inclination; when the driving assembly 4 drives the second end 62 of the second linkage 6 to rotate counterclockwise forward, the second end 62 of the second linkage 6 rotates downward around the first end 61, and the third end 63 also rotates counterclockwise downward around the first end 61 accordingly, the third end 63 drives the first linkage 5 to rotate counterclockwise downward, the first linkage 5 drives the front end of the cushion edge plate 3 to rotate counterclockwise, and the first linkage 5 drives the front end of the cushion edge plate 3 to rotate counterclockwise downward relative to the mounting bracket 2, so that the cushion edge plate 3 reduces the backward inclination angle. For example, the cushion edge plate 3 can drive the cushion to adjust to a zero-gravity seat mode (the seat inclination angle simulates the zero-gravity angle of a space capsule, this mode can present the most comfortable sitting posture, and can maximize the comfort of the passengers, in this sitting posture, the human body is most relaxed, and the load generated by the human body is also the smallest, even if this posture is maintained for a long time, there will be no fatigue).

[0041] Moreover, compared with the conventional three-link angle adjustment mechanism, the number of the linkage force receiving members in the present case is more, the force receiving path is more dispersed, the weight and the space mode are larger, which is beneficial to improve the overall bending and torsional stiffness and structural strength of the angle adjustment mechanism 100, reduce the risk of structural deformation, and improve the running stability; compared with the conventional four-link angle adjustment mechanism, the height of the rear end of the seat frame does not need to be reduced to achieve the overall reclining effect of the seat (that is, the height of the rear end of the seat cushion edge plate remains unchanged, only the height of the front end of the seat cushion edge plate is raised), which can avoid the risk of collision between the seat cushion edge plate 3 and the vehicle floor due to the reduction of the rear end of the seat frame, and the number of the linkage force receiving members in the present case is more, the force receiving path is more dispersed, which is beneficial to improve the overall rigidity of the angle adjustment mechanism 100, reduce the risk of deformation, and improve the running stability.

[0042] In addition, the angle adjustment mechanism 100 in the present case has higher interchangeability with the basic configuration of the seat, which can be used as an independent module. When the seat does not require the angle adjustment mechanism 100, only the connection between the seat cushion edge plate 3 and the first linkage member 5 and the driving assembly 4, and the second linkage member 6 and the base bracket 1 needs to be disconnected to realize the connection between the seat body and the basic frame. This is beneficial to improve the universality and selectability of the angle adjustment mechanism 100.

[0043] Therefore, by providing the angle adjustment mechanism 100, the smoothness and stability of the seat during the adjustment of the reclining angle can be improved, and the structural strength is high.

[0044] According to some optional embodiments of the present application, as shown in Figures 1-6 The first end 61, the second end 62 and the third end 63 of the second linkage member 6 are located at the end points of the outer peripheral edge of the second linkage member 6, and the first end 61, the second end 62 and the third end 63 are sequentially connected to form a triangular shape.

[0045] For example, the first end 61, the second end 62 and the third end 63 of the second linkage member 6 are sequentially connected in a triangular shape, the triangular shape has structural stability, and the three sides support each other, which is beneficial to reduce the risk of deformation of the second linkage member 6, thereby effectively improving the structural stability of the second linkage member 6.

[0047] Further, the screw rod 421 is in threaded cooperation with the screw rod sleeve 422, the driving member 41 is in transmission connection with the screw rod sleeve 422, the driving member 41 drives the screw rod sleeve 422 to rotate relative to the screw rod 421 to drive the screw rod sleeve 422 to move axially along the screw rod 421. For example, an outer thread is arranged on the outer periphery of the screw rod 421, and an inner thread is arranged on the inner wall of the screw rod sleeve 422, the outer thread on the screw rod 421 is in threaded cooperation with the inner thread of the screw rod sleeve 422, and the screw rod sleeve 422 is in transmission connection with the driving member 41, so that the screw rod 421 is driven to move relatively along the thread by driving the screw rod sleeve 422 to rotate (that is, the rotational motion of the screw rod 421 relative to the screw rod sleeve 422 is converted into the linear motion of the screw rod sleeve 422 along the screw rod 421), so that the screw rod sleeve 422 moves axially along the screw rod 421, and the screw rod sleeve 422 is connected with the second end 62 of the second linkage member 6, when the screw rod sleeve 422 moves translationally on the screw rod 421, the screw rod sleeve 422 can drive the second end 62 to rotate correspondingly around the first end 61, so as to facilitate the adjustment of the inclination angle of the cushion side plate 3.

[0048] Optionally, the driving member 41 can be a screw rod motor, the screw rod motor drives the screw rod sleeve 422 to realize the adjustment of the inclination angle of the seat, so that the disassembly and assembly are simple, and the problem of free movement of the seat during the adjustment of the inclination angle can be prevented.

[0053] In addition, the middle cross pipe 8 can uniformly and centrally arrange the first end 61 of the second linkage 6 on the left side and the first end 61 of the second linkage 6 on the right side on the structure thereof, which is conducive to improving the motion consistency of the first end 61 of the second linkage 6 on the left side and the first end 61 of the second linkage 6 on the right side, and improving the transverse structural strength between them, thereby improving the relative position stability and motion synchronization of the two second linkages 6.

[0054] Moreover, the driving assembly 4, the two second linkages 6, the front cross pipe 7 and the middle cross pipe 8 are connected as a whole, so that the above structure can be assembled as an independent module, which can be flexibly assembled on the basic skeleton of the seat according to the selection requirements of the seat, thereby improving the universality and interchangeability.
