Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology. Specifically, this utility model relates to an active side wing support mechanism for automatic assisted vehicle steering. Background Technology

[0002] As the part of the car that users have the most direct contact with, and also the one with the longest contact time and the largest contact area, the quality of the car seat's support directly affects the user's driving experience. Assessing seat support mainly involves three aspects: First, the quality of seat support when the car is stationary affects the seating posture; second, the quality of seat support when the car is traveling straight affects the physical condition during long journeys; and third, when the car is turning or navigating S-shaped roads, a well-supported seat provides stronger support, reducing the driver's body swaying during turns. With the rapid development of intelligent vehicles, seat support has become an increasingly prominent attribute and a key selling point for various car manufacturers.

[0003] A patent application with patent number 202210631636.0 and publication date of July 16, 2024, discloses an active side wing structure for automotive seats. Its key feature is that it is applied to the seat body and includes a side wing support airbag, a detection airbag, and a solenoid valve assembly. The side wing support airbag is disposed on the seat body for supporting the side wings of the seat body. The detection airbag is disposed on the seat body for detecting the air pressure value of the side wings of the seat body. The solenoid valve assembly is connected to an air source and is pneumatically connected to the side wing support airbag and the detection airbag. The beneficial effect of this application is that, by using the detection airbag, the pressure exerted on the detection airbag by the driver during vehicle steering is adjusted to regulate the air pressure of the side wing support airbag to support the human body, achieving a timely support and protection function, and improving the safety and comfort of the driver and passengers.

[0004] Currently available technologies include the following: First, adjustment is achieved through air pump inflation, but this technology is slow and noisy. Second, the middle layer of the seat is inflated, and the side wing support is adjusted through an air pump and valve, but this structure is too complex. Utility Model Content

[0005] The present invention aims to provide an active side wing support mechanism for automatic assisted vehicle steering that has a simple structure and can improve passenger comfort.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an active side wing support mechanism for automatic assisted vehicle steering, comprising a backrest frame, wherein the side wing support mechanisms are symmetrically arranged on both sides of the backrest frame, and a wire is provided between the two side wing support mechanisms, wherein the two side wing support mechanisms are connected by the wire signal, the side wing support mechanisms are located on both sides of the passenger, and the side wing support mechanism includes an outer wing support piece disposed on the backrest frame and an inner wing support piece disposed inside the outer wing support piece, wherein a pressure sensor and an elastic adjustment device are provided between the outer wing support piece and the inner wing support piece.

[0007] The outer wing support plate and the inner wing support plate are hinged together.

[0008] The connection point between the outer wing support piece and the inner wing support piece is located on the side of the outer wing support piece away from the backrest frame.

[0009] The pressure sensor and the elastic adjustment device are mounted on the outer wing support plate.

[0010] Both the pressure sensor and the elastic adjustment device are connected to wires, and the pressure sensor and the elastic adjustment device on both sides are connected by wires.

[0011] The elastic adjustment device is an electrically controlled spring, and the two ends of the electrically controlled spring are connected to the outer wing support plate and the inner wing support plate.

[0012] The outer wing support piece and the inner wing support piece are wrapped inside the seat cover. The outer wing support piece is perpendicular to the backrest frame, and the inner wing support piece is inclined relative to the outer wing support piece.

[0013] The technical effect of this utility model is as follows: When the vehicle turns, the centrifugal force on the human body will cause the body to twist. At this time, the side wing support system will provide corresponding support for the human body. When the side wing support mechanism on one side is subjected to force, the side wing support mechanism on the other side will make the same movement after the signal is transmitted by the wire, thereby ensuring that the occupant can still be protected by the side wing wrapping force while the body twists.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the utility model concept and technical solution, and to facilitate its implementation.

[0019] Please see Figure 1-2 An active side wing support mechanism for automatic assisted vehicle steering includes a backrest frame 1, with side wing support mechanisms symmetrically arranged on both sides of the backrest frame 1. A wire 2 is provided between the two side wing support mechanisms, and the two side wing support mechanisms are signal connected through the wire 2. The side wing support mechanisms are located on both sides of the passenger. The side wing support mechanism includes an outer wing support plate 3 disposed on the backrest frame 1 and an inner wing support plate 4 disposed inside the outer wing support plate 3. A pressure sensor 5 and an elastic adjustment device 6 are provided between the outer wing support plate 3 and the inner wing support plate 4.

[0020] When the vehicle turns, the centrifugal force on the occupants causes their bodies to twist. The side wing support mechanism provides support as the occupants press against one side of the support. When this support is subjected to force, it sends a signal, transmitted via wire 2, to the other side. Upon receiving the signal, the other side wing support moves, ensuring that the occupant remains protected by the side wings even as their body twists. The outer side wing support piece 3 is welded to the backrest frame 1 at mounting points, supporting the entire side wing support mechanism and providing a fulcrum for installation. The inner side wing support piece 4 is located on the side adjacent to the outer side wing support pieces 3, used for attaching... The pressure sensor 5 and the elastic adjustment device 6 are located between the outer wing support plate 3 and the inner wing support plate 4, respectively. When the person tilts due to inertia, the body presses on the inner wing support plate 4 on one side. The inner wing support plate 4 moves towards the outer wing support plate 3 under pressure, and the inner wing support plate 4 squeezes the pressure sensor 5. After being compressed, the pressure sensor 5 transmits a signal to the electric control spring on the other side through the wire 2. After receiving the signal, the electric control spring on the other side pushes the inner wing support plate 4 on the same side to move, so that the inner wing support plates 4 on both sides can always wrap around the sides of the person, protecting the person, without affecting the person's own body movement or twisting.

[0021] The outer wing support plate 3 and the inner wing support plate 4 are hinged together, allowing the inner wing support plate 4 to rotate freely relative to the outer wing support plate 3, thereby smoothly squeezing the pressure sensor 5 or being pushed to rotate by the electronically controlled spring.

[0022] The connection point between the outer wing support piece 3 and the inner wing support piece 4 is located on the side of the outer wing support piece 3 away from the backrest frame 1; this makes the tips of the inner wing support piece 4 and the outer wing support piece 3 face outward, forming a shape structure that is narrow on the outside and wide on the inside, making it convenient for passengers to lean against the backrest.

[0023] The pressure sensor 5 and the elastic adjustment device 6 are mounted on the outer wing support plate 3. Since the outer wing support plate 3 is mounted on the backrest frame 1, it can provide support for the pressure sensor 5 and the elastic adjustment device 6, ensuring stability.

[0024] Both the pressure sensor 5 and the elastic adjustment device 6 are connected to the wire 2. The pressure sensor 5 and the elastic adjustment device 6 on both sides are connected by the wire 2. The inner wing support plate 4 presses on the pressure sensor 5. The pressure sensor 5 sends a signal to the elastic adjustment device 6 on the other side through the wire 2. After receiving the signal, the elastic adjustment device 6 takes action, forming a complete record of receiving pressure - sending a signal - receiving a signal - making a feedback.

[0025] The elastic adjustment device 6 is an electrically controlled spring, with both ends of the electrically controlled spring connected to the outer wing support plate 3 and the inner wing support plate 4; the electrically controlled spring can control the inner wing support plate 4 to rotate after receiving a signal.

[0026] The outer wing support plate 3 and the inner wing support plate 4 are wrapped inside the seat cover. The outer wing support plate 3 is perpendicular to the backrest frame 1, and the inner wing support plate 4 is inclined relative to the outer wing support plate 3. The cover has a certain degree of elasticity, which ensures that the inner wing support plate 4 can rotate freely, and at the same time, it can wrap around the inner wing support plate 4. The occupant will not directly contact the inner wing support plate 4, thus improving the comfort of the occupant.

[0027] Working principle: When the car turns, the occupants tilt due to inertia, pressing against the inner wing support plate 4 on one side. The inner wing support plate 4 moves towards the outer wing support plate 3 under pressure, squeezing the pressure sensor 5. After being compressed, the pressure sensor 5 transmits a signal to the electronically controlled spring on the other side through the wire 2. Upon receiving the signal, the electronically controlled spring on the other side pushes the inner wing support plate 4 on the same side to move, so that the inner wing support plates 4 on both sides can always wrap around the occupants, protecting them without affecting their body movements or twisting.

[0028] The technical effect of this utility model is as follows: When the vehicle turns, the centrifugal force on the human body will cause the body to twist. At this time, the side wing support system will provide corresponding support for the human body. When the side wing support mechanism on one side is subjected to force, the side wing support mechanism on the other side will make the same movement after the signal is transmitted by the wire 2, thereby ensuring that the occupant can still be protected by the side wing wrapping force while the body twists.

[0029] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
