Drawings
Fig. 1 is a schematic structural view of a seat reclining mechanism.
Detailed Description
The present invention will be further described with reference to the following examples and the accompanying drawings.
As shown in fig. 1, a seat reclining mechanism for a vehicle seat structurally includes a base plate 1 and a seat support plate 2 located at an upper side of the base plate 1, wherein the base plate 1 may be directly assembled to a car seat frame or integrally formed with the car seat frame.
The seat supporting plate 2 is used for supporting the buttocks and the legs of passengers, a fork lifting connecting rod 3 is arranged between one end of the seat supporting plate 2 and the bottom plate 1, and the other end of the seat supporting plate is movably connected with the bottom plate 1. Install drive assembly 4 on the bottom plate 1, drive assembly 4 is used for driving 3 motions of crotch lifting connecting rod, and 3 motions of crotch lifting connecting rod can drive the corresponding end of seat backup pad 2 and rise or descend to realize that 2 inclinations of seat backup pad are adjusted, promptly: the inclination angle of the seat cushion of the automobile seat is adjusted.
In a specific embodiment, the fork lift link 3 may be disposed at the front end of the seat support plate 2, or may be disposed at the rear end of the seat support plate 2.
The following embodiments will be described by taking the fork lift link 3 disposed at the rear end of the seat support plate 2 as an example, and specifically: fork frame lift connecting rod 3 includes first connecting rod 3b and articulates the second connecting rod 3c at first connecting rod 3b middle part, and first connecting rod 3b one end articulates in 2 rear ends in seat backup pad, and the other end rotates and is connected with guide part 3a, and guide part 3a slidable mounting is on bottom plate 1, and the one end that first connecting rod 3b was kept away from to second connecting rod 3c articulates in bottom plate 1 rear end. Based on this, the driving assembly 4 drives the guiding component 3a to slide back and forth on the bottom plate 1, so as to control the up and down movement at the rear end of the seat supporting plate 2, and further realize the inclination angle adjustment of the seat supporting plate 2.
In this embodiment, the driving assembly 4 preferably adopts a screw motor structure, the screw motor structure includes a motor 4c, a screw 4b and a screw seat 4a, a slider member 6 is slidably mounted on the base plate 1, the motor 4c is fixed on the slider member 6, the screw seat 4a is fixed on the base plate 1, the screw 4b is in threaded connection with the screw seat 4a, and the guide member 3a of the fork-lift connecting rod 3 is fixedly connected with the slider member 6. Based on this, the motor 4c drives the screw rod 4b to rotate, i.e. the slider component 6 can be driven to slide back and forth, thereby realizing the back and forth sliding of the guide component 3 a.
The front end of the seat supporting plate 2 is movably connected with the bottom plate 1, so that when the rear end of the seat supporting plate 2 moves up and down, the seat supporting plate 2 can rotate adaptively, and the movement interference is avoided.
The movable connection structure between the front end of the seat supporting plate 2 and the bottom plate 1 has two implementation modes as follows:
