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

[0058] Such as Figure 1-10 As shown, the height adjustment system 10 includes a height adjustment motor 1, a connecting rod assembly 2, a self-locking assembly 3 and a turning assembly 4,

[0059] After the height adjustment motor 1 drives the connecting rod assembly 2 to move, the connecting rod assembly 2 drives the turning assembly 4 to turn up and down,

[0060] The self-locking assembly 3 is installed on the connecting rod assembly 2, when the height adjustment motor 1 drives the connecting rod assembly 2, the self-locking assembly 3 unlocks the connecting rod assembly 2, so that the connecting rod assembly 2 can drive the turning assembly 4 to turn up and down;

[0061] When the overturning component 4 is pressed down by the seat, the overturning component 4 drives the connecting rod component 2 , and the connecting rod component 2 drives the self-locking component 3 to lock with the connecting rod component 2 .

[0062] In this embodiment, the height adjustment system...

Embodiment 2

[0106] Such as Figure 11 As shown, the seat fixing device includes the height adjustment system 10 in the first embodiment and its modification.

[0107] Further, the seat fixing device also includes a seat positioning system, the seat positioning system includes a longitudinal positioning assembly 20 and a transverse positioning assembly 30, the longitudinal positioning assembly 20 is used for longitudinally positioning the seat, and the transverse positioning assembly 30 is used for horizontally positioning seat.

[0108] Specifically, as Figure 11 As shown, the longitudinal positioning assembly 20 and the lateral positioning assembly 30 are installed on the flipping plate 41. After the longitudinal positioning assembly 20 and the lateral positioning assembly 30 are positioned with the seat, when the flipping plate 41 is turned up and down, the seat can be adjusted to adjust the height and height together. angle.

[0109] The longitudinal positioning assembly 20 include...

Abstract

The invention discloses a height adjusting system. The system comprises a height adjusting motor, a connecting rod assembly, a self-locking assembly and an overturning assembly. The height adjusting motor drives the connecting rod assembly to move; the connecting rod assembly drives the overturning assembly to turn over up and down, the self-locking assembly is installed on the connecting rod assembly, and when the height adjusting 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 assembly to turn over up and down. When the overturning assembly is pressed downwards by a seat, the overturning assembly drives the connecting rod assembly, and the connecting rod assembly drives the self-locking assembly to be locked with the connecting rod assembly. According to the height adjusting system and a seat fixing device, the seat can be accurately adjusted, operation is convenient,and scratching and seat framework deformation are avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a height adjustment system and a seat fixing device. Background technique [0002] Car seats play an important role in the safety and comfort of vehicles. Various evaluations and experimental verifications of car seats are required in the vehicle development process, and car seat fixing devices are also diversified. With the rapid development of car seats and the continuous change and improvement of their structures, conventional car seat fixing devices can no longer meet the fast, universal and convenient car seat fixing requirements. So it is necessary to make a new design for the fixing device of the car seat. [0003] Seat anchorages currently come in two forms: [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 ...
