Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat technology, and in particular to a fracture-resistant automotive seat frame. Background Technology
[0002] Car seats are basically divided into two types: leather seats and cloth seats. Car seats are supported by a car seat frame, which includes the backrest frame and the seat frame. With the increasing prevalence of automobiles, different types of car seat frames have emerged on the market.
[0003] During driving, when encountering sudden situations, emergency braking is often required, and the people in the car are often subjected to extremely strong impact forces. However, the car seat frame structure on the market is complex, has low strength, and poor impact resistance, which often leads to the car seat breaking under strong impact forces, thus seriously threatening the personal safety of the people sitting in the seat. Furthermore, due to the poor impact resistance of the car seat frame, it often breaks or fractures during use, resulting in a significant reduction in the lifespan of the car seat frame, making it difficult to meet people's usage needs. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a fracture-resistant car seat frame.
[0005] One of the objectives of this utility model is achieved through the following technical solution:
[0006] A fracture-resistant car seat frame includes a seat cushion, a backrest mounted on the top of the seat cushion, and a base frame mounted on the bottom of the seat cushion. Mounting brackets are provided near the left and right sides of the bottom of the base frame. Two second rotating shafts are located between the two mounting brackets. A first rotating shaft is located at the top of each of the second rotating shafts. Two connecting pieces are provided on the left and right sides of the base frame. The connecting pieces are fixedly sleeved on the outside of the first and second rotating shafts. A connecting rod is movably connected to the side of the first rotating shaft near the center of the base frame. A movable frame is movably connected to the bottom end of the connecting rod. A limiting rod is provided on the inner side of the mounting bracket. A first spring and two second springs are sleeved on the outer edge of the limiting rod.
[0007] Furthermore, the two ends of the second rotating shaft are rotatably connected to the adjacent mounting bracket, and the two ends of the first rotating shaft are rotatably connected to the base frame.
[0008] Furthermore, the two ends of the limiting rod can move through the adjacent movable frame, and the two ends of the limiting rod are fixedly connected to the fixing plate, which is fixedly connected to the bottom inner side of the mounting frame.
[0009] Furthermore, two connecting plates are provided at both ends of the connecting rod, and pins are rotatably connected to both ends of the connecting rod. The two ends of the pins are fixedly connected to the connecting plates, the connecting plate at the top of the connecting rod is fixedly connected to the first rotating shaft, and the connecting plate at the bottom of the connecting rod is fixedly connected to the movable frame.
[0010] Furthermore, the first spring is located between the two movable frames, and the two ends of the second spring are fixedly connected to the movable frame and the fixed plate, respectively.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model discloses a fracture-resistant car seat frame. During use, when the car is subjected to bumps, the seat moves forward or backward due to inertia. At this time, the base frame and the seat cushion move together. The base frame drives the connecting piece to deflect through the first rotating shaft. The first rotating shaft then pushes the movable frame to move through the connecting rod. The movable frame moves on the outer edge of the limiting rod. At the same time, the first spring and two second springs are stretched and compressed respectively, which together play a buffering role, thereby preventing the base frame and mounting frame from breaking due to lack of buffering, thus playing a fracture-resistant role.

[0023] Working principle: This utility model discloses a fracture-resistant car seat frame. During use, when the car is subjected to bumps, the seat moves forward or backward due to inertia. At this time, the base frame 3 and the seat cushion 1 move together. The base frame 3 drives the connecting piece 5 to deflect through the first rotating shaft 6.
