[0002] When a car collides, the lives of the driver and passengers will be threatened, so the safety of the car cannot protect the safety of the passengers. However, when the side of the car is hit, there is no other protective structure except the airbag.

[0003] Prior art CN103661029B discloses an energy-absorbing car seat, which includes a base, a mounting seat located above the base, and a seat mounted on the upper end of the mounting seat, wherein the mounting seat can slide relative to the base, and a plurality of energy-absorbing blocks are arranged between the mounting seat and the base, and when the mounting seat is displaced relative to the base, the energy-absorbing blocks are squeezed and deformed to provide a buffering force to the seat, and the energy-absorbing blocks are made of energy-absorbing materials. The purpose of the present invention is to provide an energy-absorbing car seat, which can effectively buffer the impact from both sides of the seat.

[0004] The above device cushions the car seat through the energy-absorbing block to prevent the occupants from being injured. However, the passengers will still move sideways under the action of inertia and collide with hard objects on the side of the seat, resulting in a low protection effect and failure to effectively protect the passengers. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-side impact protection structure for a car seat, which solves the problem that after an existing energy-absorbing car seat is hit on the side of the vehicle, the passenger will still move sideways under the action of inertia and collide with hard objects on the side of the seat, resulting in a low protection effect and failure to effectively protect the passenger.

[0006] To achieve the above object, the present invention provides a side impact protection structure for a car seat, comprising a seat body, characterized in that:

[0007] Also included are protection components;

[0008] The protective component includes a base, a slide, a support plate, an airbag, a buffer and an inflatable component.

DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0025] First embodiment:

[0026] See also Figures 1 to 4 ,in Figure 1 It is a schematic diagram of the overall structure of the car seat anti-side impact protection structure. Figure 2 This is a schematic diagram of the installation structure of the slide. Figure 3 This is a schematic diagram of the installation structure of the inflatable component. Figure 4 It is a schematic diagram of the installation structure of the airbag.

[0027] The present invention provides an anti-side impact protection structure for a car seat, comprising a seat body 101 and a protection component 102, wherein the protection component 102 comprises a base 103, a slide seat 104, a support plate 105, an airbag 106, a buffer 107, an inflatable component 108 and a guide rod 116, wherein the inflatable component 108 comprises a cylinder body 109, a piston rod 110, a piston 111 and an air pipe 112, wherein the piston rod 110 comprises a rod body 113 and a rubber head 114, and the inflatable component 108 further comprises a pressure relief valve 115. When a vehicle is hit from the side, the airbag 106 is inflated through the inflatable component 108, thereby causing the airbag 106 to expand and drive the support plate 105 to extend, and the passenger is supported by the support plate 105, and the airbag 106 is used for buffering at the same time to reduce the damage to the passenger. It can be understood that the above scheme can be used to protect passengers when the vehicle is hit from the side, and can also be used to inflate the airbag 106.

[0028] According to this specific embodiment, the seat body 101 is composed of a seat cushion and a backrest, and a groove is provided on the seat cushion for accommodating the support plate 105 and the airbag 106 .

[0029] The slide 104 is fixedly connected to the seat body 101 and is located at the bottom of the seat body 101. The base 103 is slidably connected to the slide 104 and is sleeved on the slide 104. The support plate 105 is slidably connected to the seat body 101 and is located inside the seat body 101. The airbag 106 is connected to the support plate 105 and is connected to the seat body 101 and is located inside the seat body 101. The buffer 107 is connected to the slide 104 and is connected to the seat body 101. The base 103 is abutted and arranged on the slide 104, and the inflatable component 108 is arranged on the slide 104; the base 103 is installed on the vehicle body, and the buffer 107 is provided with four, and two are arranged on the left and right sides of the slide 104 as a group, and the impacted head of the buffer 107 is abutted with the base 103, and the support plate 105 and the airbag 106 are provided with two, and are respectively located on the left and right sides of the seat body 101, so that it can be ensured that the vehicle can provide a left or right impact. In order to provide effective protection, two inflatable components 108 are provided, and can deliver air to the airbag 106 on the impacted side after the vehicle is hit from the side. When in use, under normal circumstances, the support plate 105 and the airbag 106 are retracted into the seat body 101 to avoid affecting the passengers. When the vehicle is hit from the side, the vehicle moves and drives the base 103 to move. At this time, the slide seat 104 remains stationary under the action of inertia, and the inner side wall of the base 103 abuts against the buffer 107, which quickly absorbs the force of the impact. The impact energy is dispersed, reducing the impact force on the seat body 101 and the passenger. At the same time, the inflatable component 108 inflates the airbag 106, thereby inflating the airbag 106 on the impacted side and driving the support plate 105 to extend out of the seat body 101. At this time, the passenger's side is supported by the support plate 105 to prevent the passenger from colliding with hard objects on the side of the seat body 101 and getting injured. At the same time, the inflated airbag 106 cushions the passenger to further prevent the passenger from getting injured, thereby achieving the purpose of improving the protection effect on the passenger.

[0030] Secondly, the cylinder body 109 is fixedly connected to the slide seat 104 and is located inside the slide seat 104; the piston 111 is slidably connected to the cylinder body 109 and is located inside the cylinder body 109; the piston rod 110 is fixedly connected to the cylinder body 109 and is located on one side of the cylinder body 109; the two ends of the air pipe 112 are respectively connected to the cylinder body 109 and the airbag 106, and the air pipe 112 is arranged on the seat body 101; when the vehicle is hit and drives the base 103 to move, the side wall of the base 103 drives the piston rod 110 to move, so that the piston rod 110 drives the piston 111 to move, and the movement of the piston 111 pushes the air inside the cylinder body 109 into the air pipe 112, and injects the air into the airbag 106 through the air pipe 112, thereby achieving the purpose of inflating the airbag 106.

[0031] At the same time, the rod body 113 is fixedly connected to the piston 111 and is located on one side of the piston 111; the rubber head 114 is fixedly connected to the rod body 113 and is located on a side of the rod body 113 away from the piston 111; the rubber head 114 is used to buffer the impact between the base 103 and the piston rod 110 to avoid bending of the piston rod 110 due to excessive impact force, thereby affecting the inflation of the airbag 106.

[0032] In addition, the pressure relief valve 115 is connected to the cylinder body 109, communicates with the cylinder body 109, and is located on one side of the cylinder body 109; in order to quickly inflate the airbag 106, the piston 111 can fill the airbag 106 with air by moving a shorter stroke, but as the seat body 101 continues to move, if the piston 111 continues to compress the air in the cylinder body 109, the internal air pressure of the airbag 106 will continue to increase. When the air pressure exceeds a certain limit, the airbag 106 may explode, causing secondary damage to the passenger; therefore, the pressure relief valve 115 is set so that when the internal air pressure of the airbag 106 reaches a preset safety value, the pressure relief valve 115 will automatically open, allowing the gas to be discharged through the pressure relief valve 115, thereby preventing the airbag 106 from exploding.

[0033] Finally, the guide rod 116 is fixedly connected to the base 103, and is slidably connected to the slide 104, and passes through the slide 104; the movement of the slide 104 and the seat body 101 is guided by the guide rod 116, so that the slide 104 and the seat body 101 can only move along the length direction of the guide rod 116, thereby improving the stability of the seat body 101 when moving.

[0034] When the automobile seat side impact protection structure of this embodiment is used, when the vehicle is hit from the side, the vehicle moves and drives the base 103 to move. At this time, the slide 104 and the seat body 101 move relative to the base 103 under the action of inertia, so that the base 103 squeezes the piston rod 110 to move and drives the piston 111 to move. When the piston 111 moves in the cylinder 109, the air inside the cylinder 109 is pushed into the air pipe 112, and the air is injected into the airbag 106 through the air pipe 112 to expand the airbag 106, thereby driving the support plate 105 to extend out of the seat body 101. At this time, the passenger is supported by the support plate 105, and the impact on the passenger is buffered by the airbag 106, thereby achieving the purpose of protecting the passenger; at the same time, the impact energy is absorbed by the buffer 107 to reduce the impact transmitted to the slide 104 and the seat body 101, thereby further protecting the passenger.

[0035] Second embodiment:

[0036] Based on the first embodiment, please refer to Figure 5 , Figure 5 It is a schematic diagram of the overall structure of the automobile seat side impact protection structure of the second embodiment.

[0037] For this specific implementation, four airbags 106 and support plates 105 are provided in this embodiment, two of which are provided on the seat cushion of the seat body 101, and the other two are provided on the backrest of the seat body 101. The two airbags 106 on the same side share a cylinder 109 for inflation. The support plates 105 and the airbags 106 on the backrest and the seat cushion have the same structure and the same movement principle, which will not be elaborated here. In this way, when the vehicle is hit, the support plates 105 on the backrest and the seat cushion of the seat body 101 are extended to further protect the upper body of the passenger and enhance the protection effect.

[0038] Second embodiment:

[0039] Based on the first embodiment, please refer to Figure 6 , Figure 6 It is a structural schematic diagram of the top plate of the second embodiment. The support plate 105 of this embodiment includes a side plate 201 and a top plate 202. The side plate 201 has a limiting protrusion 203, and the top plate 202 includes an elastic plate 206, a decorative panel 207, a magnetic plate 208 and an adsorption plate 209.

[0040] According to this specific embodiment, the side panel 201 is slidably connected to the seat body 101 and is located inside the seat body 101; the top panel 202 is connected to the side panel 201 and to the airbag 106, and is located on the top of the side panel 201; the side panel 201 is used to support the passengers, and the top panel 202 is used to seal the groove on the seat cushion to prevent the groove on the seat cushion for accommodating the support plate 105 from affecting the passengers' sitting and preventing debris from entering.

[0041] Among them, the limiting protrusion 203 is arranged on the side panel 201 and is located on one side of the side panel 201; the limiting groove 204 is arranged on the side of the seat body 101 close to the limiting protrusion 203, and the limiting groove 204 cooperates with the limiting protrusion 203; the limiting protrusion 203 can slide in the limiting groove 204, thereby making the side panel 201 slide in the formation of the limiting groove 204, avoiding the side panel 201 from being separated from the seat body 101.

[0042] Secondly, the limiting protrusion 203 is arranged on the side panel 201 and is located on one side of the side panel 201; the seat body 101 has a limiting groove 204, and the limiting groove 204 is arranged on the side of the seat body 101 close to the limiting protrusion 203, and the limiting groove 204 cooperates with the limiting protrusion 203; the elastic plate 206 is made of elastic material, such as rubber, so as to avoid the top plate 202 from causing harm to the passenger when it contacts the passenger's body. At the same time, the material of the decorative panel 207 is consistent with the surface material of the seat body 101, so as to further enhance the aesthetics of the seat body 101 without affecting the normal function.

[0043] At the same time, the magnetic plate 208 is fixedly connected to the seat body 101 and is arranged on the seat body 101; the adsorption plate 209 is connected to the elastic plate 206 and is located on the side of the elastic plate 206 close to the magnetic plate 208; the magnetic plate 208 and the adsorption plate 209 can be adsorbed to each other under the action of magnetic force. When the top plate 202 is retracted into the seat body 101, the adsorption plate 209 is adsorbed by the magnetic plate 208, thereby ensuring the stability of the support plate 105 when it is in the seat body 101. At the same time, the magnetic force is weak to avoid affecting the normal extension of the support plate 105.
