Abstract
Description
Technical Field
[0001] This application relates to the field of seat frame technology, and more particularly to a car seat frame with a cushioning function. Background Technology
[0002] Automobiles are one of the most important means of transportation today. Car seats are the seats you sit on when you ride in a car. A car seat consists of a headrest, backrest, and seat cushion. Car seats can be divided into front seats and rear seats according to their installation position. A car seat consists of a car seat frame and an outer leather layer. After the car seat frame is assembled and welded, the outer leather layer is fitted and sewn onto the outside of the car seat frame.
[0003] Currently, car seats on the market are simply made of ordinary seat frames. Therefore, when a car is involved in a collision, because there is no good cushioning device on the rear side of the seat frame, rear passengers will directly hit the seat frame, causing passenger injuries. Therefore, in order to correct the above defects, we propose a car seat frame with cushioning function. Utility Model Content
[0004] In view of the above problems, this application provides a car seat frame with a cushioning function to solve the problem that the rear side of the seat frame does not have a good cushioning device, so the rear passenger will directly hit the seat frame and cause injury to the passenger.
[0005] This application provides a car seat frame with a cushioning function, including a seat frame body: a pair of limiting plates are fixedly connected to the backrest of the seat frame body, a movable plate is provided in the pair of limiting plates, a rectangular groove is opened on the side wall of the movable plate, a plurality of springs are fixedly connected between the rectangular groove and the side wall of the seat frame body, a sponge plate is fixedly connected to the side wall of the movable plate, a plurality of elastic bands are fixedly connected to the side wall of the pair of limiting plates, and a shock absorption mechanism is provided at the bottom of the seat frame body.
[0006] In some embodiments, a plurality of the elastic bands are equidistantly distributed on a pair of limiting plates, and the distance between the pair of limiting plates is equal to the height of the movable plate.
[0007] In some embodiments, the shock absorption mechanism includes a support plate with two pairs of first bolts passing through it, and a plurality of shock absorbers are provided between the support plate and the seat frame body. Each shock absorber has a connecting block fixedly connected to its top and bottom, and a plurality of second bolts passing through the connecting block. The bottom of the seat frame body and the top of the support plate are provided with threaded grooves that match the second bolts.
[0008] In some embodiments, two pairs of limiting cylinders are fixedly connected to the top of the support plate, and limiting rods are provided inside the limiting cylinders. The top ends of the limiting rods are fixedly connected to the bottom of the seat frame body.
[0009] In some embodiments, a plurality of the shock absorbers are equidistantly distributed at the bottom of the seat frame body.
[0010] In some embodiments, the diameter of the two pairs of limiting rods is equal to the inner diameter of the limiting cylinder, and the two pairs of limiting cylinders are symmetrically arranged about the central axis of the support plate.
[0011] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.
[0012] 1. Through the arrangement of elastic bands, sponge plates, movable plates, and springs, when a car is involved in a collision, the human body leans forward and hits the back of the seat frame. The elastic band provides initial cushioning, followed by impact with the sponge plate for secondary cushioning. At the same time, the impact force compresses the movable plate, which in turn compresses the spring. Thus, the spring provides a third level of cushioning, thereby protecting the human body.
[0013] 2. Through the installation of the shock absorber, seat frame body, connecting block and second bolt, vibration is generated during vehicle operation. The seat frame body compresses the shock absorber, thereby absorbing and buffering the vibration of the seat frame body and improving passenger ride comfort. When the shock absorber needs to be replaced, unscrew the second bolt, remove the shock absorber and connecting block, place the new shock absorber at the replacement location, and then tighten the second bolt again to complete the replacement of the shock absorber.

[0026] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0027] This application provides a car seat frame with a cushioning function, including a seat frame body 1: a pair of limiting plates 2 are fixedly connected to the back of the seat frame body 1, a movable plate 3 is provided in the pair of limiting plates 2, a rectangular groove 4 is provided on the side wall of the movable plate 3, a plurality of springs 5 are fixedly connected between the rectangular groove 4 and the side wall of the seat frame body 1, a sponge plate 6 is fixedly connected to the side wall of the movable plate 3, a plurality of elastic bands 7 are fixedly connected to the side wall of the pair of limiting plates 2, and a shock absorption mechanism is provided at the bottom of the seat frame body 1.
[0028] In the technical solution of this application embodiment, the elastic bands 7 are equidistantly arranged to increase the protection area. Several elastic bands 7 are equidistantly distributed on a pair of limiting plates 2. The distance between the pair of limiting plates 2 is equal to the height of the movable plate 3. The seat frame body 1 can be damped by the shock absorption mechanism. The shock absorption mechanism includes a support plate 8. Two pairs of first bolts 9 pass through the support plate 8. Several shock absorbers 10 are provided between the support plate 8 and the seat frame body 1. The top and bottom of each shock absorber 10 are fixedly connected to a connecting block 11. Several second bolts 12 pass through the connecting block 11. The bottom of the seat frame body 1 and the top of the support plate 8 are provided with threaded grooves that match the second bolts 12.
[0029] In the technical solution of this application embodiment, the seat frame body 1 can be limited by the setting of the limiting cylinder 13 and the limiting rod 14. Two pairs of limiting cylinders 13 are fixedly connected to the top of the support plate 8. The limiting cylinder 13 is provided with the limiting rod 14. The top end of the limiting rod 14 is fixedly connected to the bottom of the seat frame body 1. Several shock absorbers 10 are equally distributed at the bottom of the seat frame body 1. The diameter of the two pairs of limiting rods 14 is equal to the inner diameter of the limiting cylinder 13. The two pairs of limiting cylinders 13 are symmetrically arranged about the central axis of the support plate 8.
[0030] Working principle: In use, the seat frame body 1 is installed in the vehicle frame by the first bolt 9. When the vehicle is involved in a collision, the human body leans forward and hits the back of the seat frame body 1. The elastic band 7 provides initial cushioning, and then the human body hits the sponge plate 6, which provides secondary cushioning. At the same time, the impact force compresses the movable plate 3, which in turn compresses the spring 5. Thus, the spring 5 provides tertiary cushioning, thereby protecting the human body. During vehicle operation, vibrations are generated, and the seat frame body 1 compresses the shock absorber 10. The shock absorber 10 absorbs and cushions the vibration of the seat frame body 1, improving passenger comfort. When the shock absorber 10 needs to be replaced, the second bolt 12 is unscrewed, the shock absorber 10 and connecting block 11 are removed, and the new shock absorber 10 is placed at the replacement location. The second bolt 12 is then tightened back on, thus completing the replacement of the shock absorber 10.
