Referring to fig. 1-9, fig. 1 is a connection structure diagram of a reclining mechanism and a seat body of a seat provided by the present invention, fig. 2 is an exploded view of fig. 1, fig. 3 is a relative position diagram of a lifting front frame and a slide rail assembly, fig. 4 is a simplified view of fig. 3, fig. 5 is a relative position diagram of a lifting rear frame and a slide rail assembly, fig. 6 is a simplified view of fig. 5, fig. 7 is a structure diagram of a front side bracket, a front side bracket and an upper rail, fig. 8 is a relative position diagram of a lifting front seat and a slide rail assembly, and fig. 9 is a relative position diagram of a lifting rear seat and a slide rail assembly.
As shown in fig. 1 and 2, the present invention provides a reclining device of a seat, in which: the seat comprises a seat body 1 and a backrest 2 which are connected, wherein the seat body 1 comprises a frame 11, a seat basin 12 is arranged at the front end part of the frame 11, and the rear end part of the frame 11 can be hinged; the tilt angle adjusting device includes: the front end part of the front support component 3 is hinged with the front end part of the frame 11, and the rear end part forms a fixed hinged point; the driving assembly 4 includes a driving portion 41 and a connecting portion 42, the driving portion 41 is hinged to the front support assembly 3 to form a first hinge point, the driving portion 41 is provided with a driving rod 411, the driving rod 411 is in threaded connection with the connecting portion 42, and an end portion of the connecting portion 42 far away from the driving rod 411 is also hinged to form a second hinge point.
By adopting the structure, when the driving part 41 is started, the driving rod 411 can be driven to rotate, the length of the driving rod 411 screwed into the connecting part 42 can be changed, and further the distance between the first hinge point and the second hinge point can be changed, so that the front support assembly 3 can be driven to rotate around the fixed hinge point at the rear end part of the front support assembly 3, and the front support assembly 3 can drive the seat body 1 to rotate around the hinge point at the rear end part of the seat body in the rotating process, so that the inclination angle of the seat body 1 can be adjusted, and the adjustment of the elevation angle of the backrest 2 can be realized simultaneously.
Compared with the traditional scheme that the seat basin 12 is driven to rotate around a rotating point, in the inclination angle adjusting device of the seat, the hinge point at the rear end of the seat body 1 is more backward, the space below the seat body 1 is larger, the installation and arrangement of the driving assembly 4 are facilitated, and the adjustment range of the inclination angle of the seat can be larger.
It should be noted that "screwing in" here means that the depth of the driving rod 411 screwed into the connecting portion 42 is increased, "screwing out" means that the depth of the driving rod 411 screwed into the connecting portion 42 is decreased, and does not mean that the driving rod 411 is just screwed into the connecting portion 42 or that
In a specific scheme, the front frame assembly 3 may include two front side frames 31 arranged at a distance in the transverse direction and a cross beam 32 connecting the two front side frames 31, with reference to fig. 7, the front side frames 31 may be provided with fixing holes 311c, the cross beam 32 may be fixedly mounted in the fixing holes 311c by welding or the like, so that the cross beam 32 and the front side frames 31 can rotate synchronously, the outer wall of the cross beam 32 may be provided with a driving frame 321, and the driving portion 41 may be hinged to the driving frame 321; the frame 11 may include two side plates 111 disposed at intervals in the lateral direction, and front end portions of the two front side brackets 31 may be hinged to front end portions of the two side plates 111 in a one-to-one correspondence.
Thus, after the driving part 41 is started, the two front side brackets 31 can be driven to rotate simultaneously through the cross beam 32 so as to generate driving forces for the two transverse ends of the front end part of the seat body 1 simultaneously, the synchronism of the rotation of the two transverse ends of the front end part of the seat body 1 can be ensured, and the condition that the seat body 1 inclines on one side in the adjusting process or after the adjustment can be avoided to a greater extent; and the cross beam 32 can also play a role in absorbing energy and damping vibration so as to reduce the situation of seat latent deformation in the process of vehicle collision.

When the seat is applied to a seat capable of moving back and forth, two sliding rail assemblies 5 may be transversely arranged below the seat body 1 at intervals, the sliding rail assemblies 5 may be electrically driven or manually driven, and the embodiment of fig. 2 adopts an electrically driven scheme, and at this time, the seat may further include an electrically driven assembly 6, and the specific structures of the electrically driven assembly 6 and the manual adjusting assembly may refer to the prior art, which is not limited herein; each of the slide rail assemblies 5 may include an upper rail 51 and a lower rail 52, the rear end portions of the two front brackets 31 may be hinged to the two upper rails 51 in a one-to-one correspondence, and the fixed hinged point may be located at the two upper rails 51.
It is understood that the term "fixed hinge point" as used herein means that the position of the hinge point does not change during the reclining process, and does not mean that the absolute position of the hinge point is always unchanged, for example, the fixed hinge point formed by the rear end of the front bracket 31 and the upper rail 51 in the above-mentioned solution does not change during the reclining process, but the position of the hinge point changes when the upper rail 51 slides relative to the lower rail 52.
If applied to a seat having a fixed front-rear position, the rear end portion of the front side bracket 31 may be hinged to the floor of the vehicle body, and at this time, since there is no seat front-rear displacement, the position of the formed fixed hinge point does not change.
Taking the solution of the sliding rail assembly 5 as an example, the upper rail 51 may further be provided with a front bracket 511, as shown in fig. 7, the front bracket 511 may be provided with a vertical plate portion 511a, the vertical plate portion 511a may be provided with a hinge hole 511a-1, the front bracket 31 may be hinged to the hinge hole 511a-1, and the position of the hinge hole 511a-1 is the position of the fixed hinge point.
