[0060] Figure 1 It is a structural schematic diagram of the automobile seat of the present invention.

[0061] like Figure 1As shown, the present invention discloses a car seat, which uses an adjustment mechanism 10 for the car seat. The adjustment mechanism 10 is installed between the car seat backrest 100 and the car body 200. When the angle of the car seat backrest 100 needs to be adjusted, the adjustment mechanism 10 is pulled to adjust the backrest 100 forward to a comfortable angle.

[0062] Figure 2 It is a structural schematic diagram of the adjustment mechanism of the automobile seat of the present invention. Figure 3 It is an exploded schematic diagram of the adjustment mechanism of the automobile seat of the present invention. Figure 4 This is a diagram showing the use status of the adjustment mechanism of the automobile seat of the present invention.

[0063] Figure 5 This is a schematic diagram of the adjustment mechanism of the car seat of the present invention in the unlocked state. Figure 6 This is a schematic diagram of the adjustment mechanism of the car seat of the present invention in a locked state.

[0064] like Figures 2 to 6 Specifically, the aforementioned car seat adjustment mechanism 10 comprises a base 11 and an unlocking assembly. The base 11 is in the shape of an arcuate strip, with a slot 111 defined at its front end. One end of the unlocking assembly is mounted within the slot 111, while the other end is positioned outside the base 11. Pulling the other end of the unlocking assembly causes it to move left and right along the slot 111. Furthermore, multiple evenly spaced stoppers 112 are provided on the upper and lower inner walls of the slot 111, and a stopper is provided at one end of the unlocking assembly.

[0065] Thus, when one end of the unlocking assembly moves to the position corresponding to the limit portion 112, the limit member and the limit portion 112 are in a locked state. When one end of the unlocking assembly moves away from the position corresponding to the limit portion 112, the limit member and the limit portion 112 are in an unlocked state.

[0066] Preferably, the unlocking assembly includes a sliding rod 12 and an unlocking link 13. The sliding rod 12 is mounted in the slide groove 111 of the base 11, and the unlocking link 13 is mounted in the sliding rod 12. The first end 131 of the unlocking link 13 is elastically connected to the end of the sliding rod 12 located in the slide groove 111, for example, via a spring 14. When the adjustment mechanism 10 is in the unlocked state, the rebound force of the spring 14 acts to pull the unlocking link 13 back to the locked state. The second end of the unlocking link 13 is connected to the end of the sliding rod 12 located outside the slide groove 111.

[0067] Furthermore, the sliding rod 12 includes a sliding rod body 121 and a mounting plate 122 connected as an integral body. The sliding rod body 121 is installed in the slide groove 111, and the mounting plate 122 is located outside the slide groove 111. A groove 123 is formed on the front end surface of the sliding rod body 121, and symmetrical limiting holes 124 are formed on the upper and lower end surfaces of the sliding rod body 121. Here, the limiting holes 124 are preferably circular hole structures.

[0068] In particular, the first end portion 131 of the unlocking link 13 is wedge-shaped, and the limiting member is sandwiched between the first end portion 131 of the unlocking link 13 and the groove of the sliding rod body 121. The first end portion 131 of the unlocking link 13 pushes the limiting member through the corresponding limiting hole 124 and into the corresponding limiting portion 112. The limiting member is preferably a steel ball 20, which slides in the limiting hole 124 to achieve unlocking and locking.

[0069] In addition, the second end portion 132 of the unlocking link 13 is connected to the mounting plate 122 of the sliding rod 12 via a rotary crank 30 .

[0070] Preferably, the rotating crank 30 includes a crank body 31, a first connecting portion 311 and a second connecting portion 312 extending outward from the crank body 31. The crank body 31 is connected to the mounting plate 122 via a fixed pin 40. The first connecting portion 311 is connected to a pull strap 50, and the second connecting portion 312 is connected to the other end of the unlocking link 13. The adjustment mechanism 10 changes the direction of the actuating force by rotating the crank 30, driving the unlocking link 13 to slide.

[0071] A hollow mounting boss 125 is provided on the mounting plate 122 , the crank body 31 is connected to the mounting boss 125 via a fixing pin 40 , and a bushing 60 is provided between the crank body 31 and the mounting boss 125 to reduce wear between the crank body 31 and the mounting boss 125 .

[0072] The first end 131 and the second end 132 of the unlocking link 13 are preferably configured as U-shaped hook structures. Several reinforcing ribs 133 are provided within the unlocking link 13 to enhance its strength. The unlocking link 13 is configured as an elongated rod. The rotating crank 30 is rotatably connected to the U-shaped groove structure on the unlocking link 13, thereby enabling the unlocking link 13 to slide.

[0073] In addition, the limiting portion 112 in the sliding groove 111 is configured as a semicircular groove, and the two steel balls 20 are respectively sandwiched between the first end portion 131 of the unlocking link 13 and the upper and lower inner wall surfaces of the groove of the sliding rod body 121 .

[0074] In this embodiment, the base 11, the sliding rod 12, and the unlocking link 13 are all configured to have matching arc-shaped strips. The corresponding angle of the arc between two adjacent limiting portions 112 in the slide groove 111 of the base 11 is 5°, that is, the unlocking link 13 reaches a locked position every time it moves outward at a corresponding angle of 5°. This allows the seat back to be adjusted to different angles according to the different needs of passengers.

[0075] To enhance the overall aesthetics, the adjustment mechanism 10 also includes an end cover 15 and a base cover 16. The end cover 15 is mounted on the exterior of the mounting plate 122, while the base cover 16 is mounted on the exterior of the base 11 and the unlocking assembly. The end cover 15 is concave and has an opening for the insertion and removal of the drawstring 50. The end cover 15 is preferably threadedly secured to the mounting plate 122, while the base cover 16 is preferably threadedly secured to the base 11.

[0076] In particular, in this embodiment, the limiting portion 112 is preferably an arc groove structure, the steel ball 20 slides in the limiting portion 112 (arc groove structure) of the base 11, the base 11 is a long U-shaped structure, and the sliding rod 12 slides in the U-shaped groove of the base 11.

[0077] According to the above structural description, when adjusting the car seat backrest, the pull strap 50 is pulled, rotating the crank 30, and driving the second end 132 of the unlocking link 13 outward. The wedge-shaped structure of the first end 131 of the unlocking link 13 releases the steel ball 20, causing it to fall back into the groove of the sliding rod body 121, and the adjustment mechanism 10 is unlocked. When the car seat backrest is adjusted to the desired position, the first end 131 of the unlocking link 13, due to the rebound force of the spring 14, squeezes the steel ball 20 through the wedge-shaped structure of the first end 131 of the unlocking link 13, causing the steel ball 20 to slide within the groove of the sliding rod 12, pushing the steel ball 20 upward into the corresponding limiting hole 124 of the sliding rod body 121 and embedding it in the limiting portion 112, causing the steel ball 20 to be stuck between the sliding rod 12 and the slide groove 111 of the base 11, thereby locking the adjustment mechanism 10.

[0078] Therefore, the backrest of the automobile seat of the present invention can adjust component parameters according to different rotation angle radii and adjustment angle ranges, thereby being suitable for different seats and vehicle body environments.

[0079] In summary, the car seat and its adjustment mechanism of the present invention can personalize the angle of the car seat back according to the different needs of customers. It has a simple structure, is easy to adjust, and is safe and reliable, and can effectively improve the user's riding comfort and humanized needs.
