Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat cushions, and specifically relates to an installation skeleton for an automobile seat cushion sensor. Background Technique

[0002] Automobile seat cushions are seat accessories used to provide comfortable support and protect the bodies of drivers and passengers. Their design aims to provide a comfortable seating experience and reduce fatigue caused by long-term driving or riding by reducing vibrations and pressure. Automobile seat cushion sensors play a crucial role in modern automobile design. Automobile seat cushion sensors are mainly used to measure the weight of passengers on the seat and adjust the inflation volume of the airbag according to the weight to provide more accurate safety protection. In addition, these sensors can also detect whether there is someone on the seat, thus triggering the corresponding airbag system in the event of a collision;

[0003] However, the seat will collapse after frequent use. Seat collapse refers to the deformation or sinking of the surface or internal filling of an automobile seat, resulting in the loss of the original support and comfort of the seat. This problem may have an adverse impact on the sitting postures and physical health of drivers and passengers. Therefore, the above problems need to be solved. Content of the Utility Model

[0004] The purpose of the utility model is to provide an installation skeleton for an automobile seat cushion sensor to solve the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an installation skeleton for an automobile seat cushion sensor, including;

[0006] A seat cushion structure, which includes an automobile sensor keel mounting rack, an automobile back keel bracket, an integrated automobile seat backrest, a welding part A, an automobile seat balance push rod, an automobile seat cavity tube, a lower connecting block, and a compressed gas storage tank;

[0007] The end of the automobile back keel bracket is integrally fixed to the end of the automobile sensor keel mounting rack. The automobile sensor keel mounting rack and the automobile back keel bracket are combined to form a "U" shape. The bottom of the integrated automobile seat backrest is integrally fixed to the end of the automobile back keel bracket. The integrated automobile seat backrest is perpendicular to the automobile back keel bracket;

[0008] There are multiple automotive seat balance push rods, which are located between the automotive sensor keel mounting bracket and the automotive back keel bracket. The top of the automotive seat balance push rod has an integrally fixed upper welding part B. The number of upper welding parts A is equal to the number of automotive seat balance push rods. The top of the upper welding part A is connected to the bottom of the automotive back keel bracket. The bottom of the upper welding part A is embedded inside the upper welding part B, and there is an upper connecting shaft at the connection between the upper welding part B and the upper welding part A. The upper welding part B is rotationally connected to the upper welding part A through the upper connecting shaft;

[0009] The inside of the automotive seat cavity tube is a hollow structure. The bottom of the automotive seat balance push rod is embedded inside the automotive seat cavity tube and is slidably connected thereto. The bottom of the automotive seat cavity tube has an integrally fixed lower welding part. There are multiple lower link blocks. The number of lower link blocks is equal to the number of automotive seat cavity tubes. The bottom of the lower link block is fixedly connected to the top of the automotive sensor keel mounting bracket. The top of the lower link block is embedded inside the lower welding part, and there is a lower connecting shaft at the connection between the lower welding part and the lower link block. The lower welding part is rotationally connected to the lower link block through the lower connecting shaft;

[0010] The compressed gas storage tank is located on the top of the automotive sensor keel mounting bracket, and there are two symmetric gas transmission pipes on both sides of the compressed gas storage tank;

[0011] The top of the automotive back keel bracket has an automotive pressure sensing seat cushion, and there are multiple pressure sensors on the automotive pressure sensing seat cushion.

[0012] Preferably, the outside of the automotive seat cavity tube has an integrally fixed cavity tube intake pipe, and the end of the gas transmission pipe is connected to the cavity tube intake pipe and sealed by a nut connection.

[0013] Preferably, a groove B is provided at the top of the automotive seat cavity tube. Inside the groove B, there is a gasket B. The gasket B is fitted with the groove B, and the inner side of the gasket B is attached to the outer wall of the automotive seat balance push rod.

[0014] Preferably, a groove A is provided at the bottom of the automotive seat balance push rod. Inside the groove A, there is a gasket A. The gasket A is embedded inside the groove A, and the outer side of the gasket A is attached to the inner wall of the automotive seat cavity tube.

When the user sits on the car pressure sensing seat cushion, when the pressure value of the car pressure sensing seat cushion reaches the set threshold, the solenoid valve is controlled to open. When the gas transmission pipe is opened, the compressed gas inside the compressed gas storage box enters the interior of the car seat cavity tube through the gas transmission pipe, so that the pressure inside the car seat cavity tube is increased. When the user sits on the car pressure sensing seat cushion, the car back keel bracket is pressed down, and the car seat balance push rod moves downward, so that the space inside the car seat cavity tube is compressed, thereby performing shock absorption and buffering, and supporting and stabilizing through air. When the user's weight is heavy, the solenoid valve is normally open, and the space inside the car seat cavity tube is compressed through the gas transmission pipe. The transmission pipe is connected to a compressed gas storage box, and the pressure value inside the compressed gas storage box is used for buffering. It is suitable for a wider range of people. When the user leaves the car seat, the gas inside the car seat cavity tube pushes the car seat balance push rod to rebound, so that the car back keel bracket is reset. This structure is not prone to seat collapse. The car sensor keel mounting frame, the car back keel bracket and the integrated car seat backrest are made of rigid material with good resilience; the car seat balance push rod and the car seat cavity tube are double-sealed by sealing pad A and sealing pad B to avoid gas leakage; the gas transmission pipe is made of hose material, which can be linked when the car seat cavity tube rotates axially. The utility model cooperates with the car sensor keel mounting frame and the cushion structure and links them through an electromagnetic valve, which can effectively alleviate the problem of seat collapse.
