Description

A lightweight and high-hardness frame for automobile seats

Technical Field

The utility model relates to the technical field of automobile accessories, in particular to a lightweight and high-hardness frame for automobile seats.

Background Art

With the continuous advancement of science and technology, people now have more and more types of transportation to choose from. When using these transportation tools, people not only pursue speed and convenience, but also have higher and higher requirements for travel safety. Buses and cars are one of the most frequently used transportation tools for people to travel. As one of the safety parts of the car, the strength of the seat frame plays an important role in the safety of the whole vehicle. The seat frame is generally supported by a steel plate, and then a sponge is wrapped around the outside of the seat frame as a buffer.

However, in the existing equipment, the seats supported by steel plates are of large mass, and simply using sponges as buffers not only has poor buffering effects, but also the overly thick sponge wrapping has poor ventilation and reduces comfort. Therefore, a lightweight and high-hardness frame for car seats is proposed.

2. Compared with the prior art, the car seat uses a lightweight and high-hardness frame. By arranging multiple aluminum alloy support plates on the backrest frame, the supporting strength of the backrest frame can be improved. By arranging an aluminum alloy load-bearing plate in the seat cushion frame, it can not only improve the overall strength of the seat cushion frame but also reduce the overall weight, thereby improving the practicability of the equipment.

DETAILED DESCRIPTION

The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

According to Figures 1 to 4, the utility model provides a lightweight and high-hardness frame for a car seat: it includes a cushion frame 1 and two slideways 2, a plurality of connecting blocks 3 are fixedly provided at the bottom of the cushion frame 1, a plurality of connecting blocks 3 are fixedly provided at the bottom of each of the connecting blocks 3, the slides 4 are movably connected to the slideways 2, a rotating rod 5 is movably provided on the cushion frame 1, mounting grooves are provided on the inner walls of both sides of the cushion frame 1, bearings are fixedly provided in the mounting grooves, the inner rings of the bearings are fixedly sleeved at both ends of the rotating rod 5, a backrest frame 6 is fixedly provided on the top of the rotating rod 5, a plurality of support plates 7 are fixedly provided in the backrest frame 6, a load-bearing plate 9 is movably provided in the cushion frame 1, and the load-bearing plate 9 and support plates 7 are made of super-hard aluminum alloy, there are four support plates 7, and the four support plates 7 are equidistantly arrayed on the inner side of the backrest frame 6, two limit grooves 8 are provided on the inner walls on both sides of the seat cushion frame 1, and limit blocks 10 are movably provided in the two groups of limit grooves 8, and the sides of the two groups of limit blocks 10 that are close to each other are respectively fixedly connected to the two sides of the load-bearing plate 9, and buffer structures 11 are provided on the inner walls on both sides of the seat cushion frame 1, and the buffer structure 11 includes a transverse plate 111 fixedly installed with the seat cushion frame 1, and a plurality of first springs 112 are fixedly provided on the top of the transverse plate 111, and the top of the first spring 112 is fixedly connected to the bottom of the load-bearing plate 9;

A shock absorbing structure 12 is provided on the top of the load-bearing plate 9, and the shock absorbing structure 12 includes multiple dampers 121 fixedly installed on the top of the load-bearing plate 9. The output ends of the multiple dampers 121 are fixedly provided with the same mounting frame 123. A second spring 122 is sleeved on the damper 121. The top of the second spring 122 is fixedly connected to the bottom of the mounting frame 123. A mesh body 124 is provided in the mounting frame 123. The mesh body 124 is made of environmentally friendly PVC material. The mesh body 124 is wrapped around the surface of the mounting frame 123. The setting of the shock absorbing structure 12 and the buffer structure 11 can play a role of multiple shock absorption and buffering, which can make the sponge wrapped on the seat cushion frame 1 rebound repeatedly, thereby improving its shock absorption and buffering effect and improving the user's usage experience.

Working principle: when in use, sit on the mesh body 124, which has elasticity itself, so it can improve the comfort of the user and the ventilation of the seat. The force on the mesh body 124 will drive the installation frame 123 to move down, and the installation frame 123 will squeeze the multiple dampers 121 at the bottom. The coordinated use of the damper 121 and the second spring 122 can play a shock-absorbing role. The damper 121 then drives the load-bearing plate 9 to move down, and the load-bearing plate 9 then squeezes multiple first springs 112. When encountering bumpy roads, the coordinated use of the first spring 112, the load-bearing plate 9, the damper 121 and the second spring 122 can play a multiple shock-absorbing and buffering role, which can make the sponge wrapped on the seat cushion frame 1 rebound repeatedly, thereby improving its shock-absorbing and buffering effect and improving the user's use experience. The setting of the support plate 7 can improve the supporting strength of the backrest frame 6, and the load-bearing plate 9 made of aluminum alloy can reduce the weight of the equipment.
