Description

Technical Field

[0001] This utility model relates to the field of seat back technology, specifically to a car seat back mesh structure. Background Technology

[0002] With the development of the automotive industry, the safety and comfort of automobiles are receiving increasing attention. Currently, vehicle seat backrest mesh is generally installed in the form of steel wire mesh on the backrest spring bracket located on the side panel of the seat back. The elasticity of the spring then provides support and shock absorption for the human body. However, it has been found in use that springs have a limited lifespan and can produce abnormal noises after prolonged use. Especially with the increasing intelligence of vehicles, some vehicle seats have the function of automatically adjusting support according to different body types of drivers. This requires the entire backrest spring bracket to have a high support effect. If springs are used, the entire bracket will sag, reducing the protective force during use and posing certain risks. Therefore, this technical solution is proposed to improve the system. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing car seat backrests in terms of low support force when supported by large mass, and to provide a car seat backrest mesh structure.

[0009] Furthermore, the two ends of the support base are provided along the bottom of the connecting rod, and the support base and the connecting rod are connected by a fixing buckle.

[0010] The beneficial effects of this utility model embodiment are as follows: A connecting ring is provided at the connection between the connecting rod and the reinforcing rod, which facilitates installation and enhances the strength of the connection. Furthermore, the connecting rod deforms under stress during use, resulting in a certain deformation when the whole moves backward, reducing the impact of rigidity. The support plate is located at the lower part of the connecting rod and the reinforcing plate, and a connecting plate for locking the connecting rod is provided at the upper part of the support plate, ensuring a stable connection between the connecting rod and the support plate. The connecting block is located on the side of the connecting plate, with its tail offset to the back side. The connecting block increases the connection point, ensuring the stability of the stressed part. Qualitative design increases the stability of the support plate, helps distribute pressure on the seat back, and improves seat durability. The bottom of the air distribution device has multiple connecting pipes that connect to the airbags on the seat, inflating multiple airbags and controlling the overall structure of the airbags. The outside of the connecting pipes is equipped with fasteners that connect to the support plate. Gas is supplied to the air distribution device through the gas tank and then evenly distributed to the airbags in various parts of the seat back through the connecting pipes. This enables intelligent adjustment and comfortable support of the seat back according to different driving postures. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See Figures 1 to 4This utility model discloses a car seat back mesh structure, mainly including key components such as connecting rods 1 connected to the back spring bracket, reinforcing rods 2, support seats 5, support plates 3, and connecting blocks 301. It achieves effective support and shock absorption for the human body, while meeting the needs of intelligent seat adjustment. The connecting rods 1, as the main supporting skeleton of the seat back mesh, are arranged horizontally in multiples, with reinforcing rods 2 on both sides to enhance the stability of the overall structure. The middle position of the connecting rods 1 is designed with a downward bend, which not only increases the fit of the seat back but also improves the comfort of the ride. A middle rod 101 is also provided through the middle position of each connecting rod 1, making the connecting rods 1 form a mesh, increasing the overall load-bearing capacity and further improving the stability of the structure. A connecting ring is provided at the connection between the connecting rods 1 and the reinforcing rods 2 for easy installation and to enhance the strength of the connection. In addition, the connecting rods 1 deform under stress during use, so that the whole structure has a certain deformation when moving backward, reducing the impact of rigidity and ensuring safety in use.

[0018] The bottom of the support seat 5 is fixed to the side panel of the seat back, and its two ends are set along the bottom of the connecting rod 1. It is connected to the connecting rod 1 by a fixing buckle 501. The end of the support seat 5 and the tail of the connecting rod 1 are not on the same plane to ensure the stability of the connection. The support seat 5 is bent backward to provide a connection point and to provide support for the overall structure, preventing the overall structure from falling and ensuring safety in use. The support seat 5 not only provides additional support for the connecting rod 1, but also enhances the stability of the entire seat back mesh structure.

[0019] The support plate 3 is located below the connecting rod 1 and the reinforcing plate, providing the main support surface for the lower part of the seat back. The upper part of the support plate 3 has a connecting plate 302 for engaging the connecting rod 1, ensuring a stable connection between the connecting rod 1 and the support plate 3. A connecting block 301 is located on the side of the connecting plate 302, with its tail angled towards the back. The connecting block 301 increases the number of connection points, ensuring the stability of the stressed parts and increasing the stability of the support plate 3. This helps to distribute the pressure on the seat back and improves the seat's durability. To further enhance seat comfort, an air distribution device 303 is located on the back of the support plate 3. The inlet of the air distribution device 303 is connected to an air tank 4. A fixing rod 401 is located on the side of the air tank 4, and the fixing rod 401 is fixed to the connecting rod 1 by a connecting buckle.
