Problems solved by technology

[0004] 1. Use 4 brackets to fix the 4 mounting holes of the seat with bolts. The fixing process requires the cooperation of multiple people, the angle of the seat cannot be adjusted accurately, and there is a risk of tools scratching the seat during the fixing process
For the type of seat with a large difference in the height of the front and rear seat legs, this method cannot adjust to the exact position of the seat, and additional pads are needed, which makes the operation complicated and the fixing firmness reduced
[0005] 2. Another way to fix the seat is to press the seat slide rail from outside to inside to fix the seat. Although it can adapt to different seat slide rail widths, it cannot adapt to different seat slide rail lengths. For seats with non-vertical outer walls of slide rails The chair cannot apply pressure, resulting in poor versatility, and the inward pressure slide rail cannot control the force, which may easily cause deformation of the seat frame. In addition, only one side force is fixed in the Y direction, and there is no fixation in the Z direction. The degree of fixation is poor. The middle slide rail will be scratched by the bolt
[0007] 1. Manual fixation cannot achieve automatic adjustment; 2. The operation is complicated and requires the cooperation of multiple people, which wastes man-hours; 3. The position of the seat cannot be adjusted accurately, resulting in deviations in experimental results; 4. There is a risk of scratching the seat with the fixing tool during the fixation process ; 5. It is easy to cause deformation of the seat frame during the fixing process

Embodiment 1

[0067] There are two slide rails 24, which are arranged in the front-rear direction of FIG.

[0068] The slider 24 is rotatably connected to one end of the push-pull rod 25, and the other end of the push-pull rod 25 is rotatably connected to the flip assembly 4.

[0070] Further, as shown in Figures 4-8, the self-locking assembly 3 is installed in the slider 23, and is sleeved outside the second screw rod 22;

[0072] When the turning assembly 4 is pressed down by the seat, the sliding block 23 is locked with the sliding rail 24 from the self-locking assembly 3.

[0077] After adjusting to a suitable height and angle, as shown in FIG. 5, when the turning assembly 4 is pressed down by the seat, the turning assembly

[0083] As shown in FIG. 8, the slider 23 is provided with a cylindrical cavity 232, and the sleeve 31 is installed in the cylindrical cavity 232.

[0084] As shown in FIG. 5 , when the flipping assembly 4 is slightly pressed down by the seat, the flipping assembly 4 dri...

Embodiment 2

[0106] As shown in FIG. 11 , the seat fixing device includes the height adjustment system 10 in the first embodiment and its modifications.

[0107] Further, the seat fixing device also includes a seat positioning system, and the seat positioning system includes a longitudinal positioning assembly

[0108] Specifically, as shown in FIG. 11 , the longitudinal positioning assembly 20 and the lateral positioning assembly 30 are mounted on the flip plate 41, and the longitudinal

[0109] The longitudinal positioning assembly 20 includes a first longitudinal positioning block 201 and a second longitudinal positioning block 202, and the first longitudinal sliding rail

[0110] The lateral positioning assembly 30 includes a first lateral positioning block 301 and a second lateral positioning block 302, and the first lateral sliding rail

[0111] The first longitudinal slide rail 203 and the second longitudinal slide rail 204 are arranged in parallel on the flip plate 41 in the longitudina...

Abstract

The invention discloses a height adjustment system, which includes a height adjustment motor, a connecting rod assembly, a self-locking assembly and an overturning assembly. After the height adjustment motor drives the connecting rod assembly to move, the connecting rod assembly drives the overturning assembly Flip up and down, the self-locking assembly is installed on the connecting rod assembly, when the height adjustment motor drives the connecting rod assembly, the self-locking assembly unlocks the connecting rod assembly, so that the connecting rod assembly can drive The overturning component is turned upside down; when the overturning component is pushed down by the seat, the overturning component drives the connecting rod component, and the connecting rod component drives the self-locking component to lock with the connecting rod component. The height adjustment system and the seat fixing device in the invention can accurately adjust the seat, facilitate operation, and avoid scratches and deformation of the seat frame.

Description

Height Adjustment System and Seat Fixtures technical field [0001] The present invention relates to the technical field of automobiles, and in particular, to a height adjustment system and a seat fixing device. Background technique Car seats play an important role in the safety and comfort of vehicles, and in the process of vehicle development, The car seat has undergone various evaluations and experimental verifications, and the fixing devices of the car seat are also diversified. With car seats With each passing day, the structure is constantly changing and improving, the conventional car seat fixing device can no longer meet the requirements of fast, universal and convenient automobile Car seat fixation requirements. Therefore, it is necessary to make a new design for the fixing device of the car seat. [0003] There are two forms of current seat fixing tooling: 1. Adopt 4 brackets to fix the 4 mounting holes of the seat with bolts, the fixing process requires th...
