Description

Technical Field

[0001] The utility model relates to the field of automobile seat cushions, in particular to a high-load return spring device for an automobile seat cushion system. Background Art

[0002] Car seat cushions are decorative and protective items used on car seats. They are usually made of comfortable materials such as cloth, leather or artificial leather, and have shock absorption, breathability and anti-slip functions. It not only provides a comfortable ride, but also effectively protects the seat from dirt, wear and damage, extending the service life of the car seat. Car seat cushions are designed in a variety of ways, including front seats, rear seats and specially designed child seat cushions. Different styles and colors of cushions can be selected according to vehicle models and personal preferences to enhance the beauty and comfort of the car interior. The design of car seat cushions that can be flipped is usually called flip seats. Its main feature is that the seat cushion or the back of the seat can be flipped up to save space or provide more cargo space. This design allows the seat to flexibly adapt to different passenger needs and space utilization in the car, especially when large items need to be placed. Flip seats are usually used in rear seats. The seat can be partially or fully flipped as needed to increase the luggage compartment capacity or provide a flat cargo area. This design makes the car trunk more flexible and more adaptable to different usage scenarios and needs.

[0003] The prior art (publication number: CN 112060990A) discloses a small school bus flap seat mechanism, which relates to the technical field of small school bus flap seats, including a flap base plate, a coil spring fixed rotating shaft and a bracket, wherein the bracket is fixedly connected to the flap base plate by an extended bolt, and a hole is opened at one end of the flap base plate close to the bracket, in which a coil spring fixed rotating shaft is fixedly installed, and the coil spring fixed rotating shaft is sleeved with a return spring.

[0004] Although the above patent connects the high-strength mounting plate with the partition frame inside the vehicle to achieve free retraction and extension of the seat and save installation space, it has the following disadvantages: when in use, the elastic force of the return spring cannot be adjusted, and it is not suitable for passengers of different weights and body shapes: Since the elastic force of the return spring is fixed, it may not be able to provide comfort and support suitable for all passengers. The comfort and support of the seat vary from person to person, and cannot be personalized according to the preferences and needs of the passengers. This may result in some passengers being unable to obtain the seat experience they expect, and further improvement is needed. For this reason, we propose a high-load return spring device for a car seat system. Utility Model Content

[0005] The main purpose of the utility model is to provide a high-load return spring device for an automobile seat cushion system, which can effectively solve the problems in the background technology.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The elastic force of the torsion spring can be adjusted by setting an adjustment component. When in use, according to the needs of the passengers, the positive and negative threaded rods are rotated to drive the two moving blocks to move away from each other. The moving blocks drive the two circular rings to move away from each other through the connecting blocks, and the torsion spring is squeezed to increase the elastic force of the torsion spring, so that the supporting force of the seat cushion is increased, and the riding feeling becomes harder. On the contrary, the positive and negative threaded rods are rotated in the opposite direction to reduce the elastic force of the torsion spring, and the riding feeling of the seat cushion becomes softer, which satisfies the preferences and needs of passengers for personalized adjustment and satisfies the passenger's seat experience.

[0016] 2. The service life of the torsion spring can be increased by setting the absorption component. When in use, the drying block can absorb the moisture in the circular groove, reduce the humidity in the air, and ensure that the torsion spring is in a dry environment, thereby effectively preventing the torsion spring from getting damp and rusting, helping to maintain its good performance, ensuring its normal elasticity and elasticity, and facilitating high-load use.

[0028] In order to adjust the softness and hardness of the seat cushion 6, the adjusting component 5 includes a box body 51. By setting the adjusting component 5, the elastic force of the torsion spring 10 can be adjusted. The box body 51 is installed at the lower front end of the seat cushion 6. The front inner wall of the box body 51 is movably connected to two movable blocks 53 symmetrically distributed on the left and right. The internal common thread sleeve of the two movable blocks 53 is provided with a forward and reverse threaded rod 52. The rear ends of the two movable blocks 53 are both installed with connecting blocks 54. The left end of the forward and reverse threaded rod 52 is movably connected to the left inner wall of the box body 51, and the right end of the forward and reverse threaded rod 52 extends to the right side of the box body 51. A through groove 8 is opened in the lower middle part of the front end of the seat cushion 6, and the through groove 8 extends into the circular groove 9. In order to be able to adjust the elastic force of the torsion spring 10, the rear ends of the two connecting blocks 54 pass through the through groove 8 and are respectively fixedly connected to the two circular rings 12.

[0029] In order to effectively prevent the torsion spring 10 from getting damp and rusting, the absorption component 7 is provided to reduce the humidity in the air and ensure that the torsion spring 10 is in a dry environment. The specific structure is as follows: the absorption component 7 includes a shell 71, and a magnet 72 is provided at the left end of the shell 71. The shell 71 is made of metal, and a plurality of openings 74 are provided at the lower end of the shell 71. A drying block 73 is provided inside the shell 71. The front inner and rear inner walls of the rectangular groove 14 are provided with a second slide groove 15. The shell 71 is slidably connected in the rectangular groove 14 through the second slide groove 15.
