Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle seats, and particularly relates to an anti-side impact protection structure for vehicle seats. Background Art

[0002] Modern vehicles have high requirements for safety performance. Since most of the vehicle seating positions are set in the middle of the vehicle, the front of the vehicle is the engine compartment, and the rear of the vehicle is the trunk. When the vehicle is impacted from the front and rear, both the engine compartment and the trunk can collapse and absorb energy, thereby reducing the impact on the occupants inside the cockpit. However, there is only a door on the side of the vehicle cockpit. When the vehicle is impacted from the side, the vehicle structure is prone to deformation, and in severe cases, it will directly invade the inside of the cockpit, causing harm to the occupants inside the vehicle.

[0003] There are few protection structures for preventing side impacts in existing vehicles. The common means of preventing side impacts is to install side airbags on the side of the vehicle body to reduce the side impact on the occupants through the side airbags. However, in some cases with a large side impact force, the side door will invade the vehicle interior and squeeze the interior space of the vehicle. Since the occupants are sitting on the vehicle seat, although the seat belt protects the occupants' personal safety to a certain extent, the seat belt and the side airbag are still not sufficient to block the collapsing door structure from harming the occupants on the seat. Therefore, a new structure is needed to protect the occupants inside the vehicle from side impacts. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an anti-side impact protection structure for vehicle seats to solve the problem that the existing structure is not sufficient to block the collapsing side door structure from harming the occupants on the seat.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: An anti-side impact protection structure for vehicle seats, comprising: A seat cushion, on which a side support and a backrest are connected; An installation base, installed on the vehicle, and a plurality of bracket telescopic cylinders with their upper ends abutting against the seat cushion are connected to the installation base. An airbag is arranged inside the bracket telescopic cylinder. A connecting rod is connected between two bracket telescopic cylinders on the same side. An installation frame is fixedly connected to the connecting rod. A plurality of card slots are formed on the installation frame. A limiting component that is clamped in the card slots is connected to the installation frame. A slider that is slidably connected to the installation frame is connected to the seat cushion.

[0006] Preferably, the limiting component includes a mounting plate fixedly installed on the installation frame, a side plate connected to the mounting plate, and a clamping block connected to the side plate. The clamping block is clamped inside the card slot, and the side of the clamping block facing the middle of the installation frame is arc-shaped.

[0007] Preferably, an outer cylinder is connected to the mounting plate. A T-shaped rod is slidably connected to the end of the outer cylinder. The end of the T-shaped rod abuts against the inner wall of the side plate. A spring is sleeved on the T-shaped rod. One end of the spring abuts against the inner wall of the T-shaped rod and the other end abuts against the inner wall of the outer cylinder. An air cavity is provided between the inner wall of the outer cylinder and the end of the T-shaped rod.

[0008] Preferably, a four-way pipe block is fixedly connected to the mounting base. An air pipe is connected between the four-way pipe block and the airbag. Electrically controlled on-off valves are respectively connected to both sides of the four-way pipe block. An air guide pipe is connected between each electrically controlled on-off valve and the mounting frame. The end of the air guide pipe communicates with the air cavity.

[0009] Preferably, a tapered bevel is provided at the end of the side plate.

[0010] Preferably, a sliding frame is connected to the mounting base. An L-shaped sliding plate is slidably connected inside the sliding frame. A supporting rod is fixedly connected to the end of the sliding plate. The supporting rod is inserted inside the side support.

[0011] Preferably, the innermost clamping block abuts against the sliding block.

[0012] Preferably, the side plate is made of spring steel, and a gap is left between the straight side surface of the clamping block and the clamping groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, a mounting base is provided under the seat cushion. At the same time, a bracket telescopic cylinder and a connecting rod are provided on the mounting base. At the same time, a mounting frame, a clamping groove and a limiting component are provided on the connecting rod. The seat cushion is connected to the mounting frame through a sliding block. The innermost limiting component restricts the position of the seat cushion through the sliding block. When the vehicle is impacted, the limiting component on the side far from the impact triggers to release the restriction on the sliding block. After the seat cushion receives the impact kinetic energy and generates displacement, the seat cushion drives the sliding block to slide on the mounting frame. The limiting component at a distance can restrict the position of the sliding block after sliding, thereby restricting the position of the seat cushion, so that the seat cushion slides and stays on the side far from the impact source, thereby enabling the passenger to stay away from the impact source, avoiding the damaged door structure at the impact source from causing harm to the passenger, effectively protecting the passenger, and avoiding greater harm to the passenger caused by a side impact of the vehicle.

Specific embodiments

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Embodiment 1:

[0017] Please refer to Figures 1 - 6 as shown, an anti-side impact protection structure for an automobile seat, comprising: A seat cushion 1, on which a side support 2 and a backrest cushion 3 are connected. The side support 2 can provide a block for the legs of the occupant to prevent the occupant from sliding off the seat cushion 1; A mounting base 4, which is installed on the vehicle, and a plurality of bracket telescopic cylinders 8 with upper ends abutted against the seat cushion 1 are connected to the mounting base 4. An airbag 9 is arranged inside the bracket telescopic cylinder 8. The airbag 9 is in an inflated state when the vehicle is not impacted. The airbag 9 is provided with a triggering component. When the vehicle is impacted, the triggering component is activated to release the gas in the airbag 9, so that the seat cushion 1 moves downward, reducing the center of gravity of the occupant and increasing the activity space of the occupant, and preventing the occupant from being stuck inside the passenger compartment. A connecting rod 14 is connected between two bracket telescopic cylinders 8 on the same side. An installation frame 15 is fixedly connected to the connecting rod 14. A plurality of card slots 16 are formed in the installation frame 15. A limit component 17 clamped in the card slots 16 is connected to the installation frame 15. A slider 18 slidably connected to the installation frame 15 is connected to the seat cushion 1.

[0018] As described above, when the vehicle is impacted on the side, the vehicle impact information triggers the limit component 17 as a trigger condition, causing the limit component 17 on the side away from the impacted side of the vehicle to be triggered. At the same time, the impact kinetic energy received by the vehicle is transmitted to the seat cushion 1. The seat cushion 1 that absorbs the kinetic energy drives the slider 18 to slide on the mounting frame 15, causing the seat cushion 1 to move away from the side of the vehicle that is impacted. When the slider 18 slides to the outermost end of the mounting frame 15, the outermost limit component 17 will catch the slider 18 to prevent the slider 18 from rebounding, thereby causing the seat cushion 1 to stop sliding at the outermost end of the mounting frame 15, so that the passengers on the seat cushion 1 stay on the side away from the vehicle impact source and reduce the harm caused by the vehicle impact to the passengers on the seat cushion 1.

[0019] Please refer to Figures 3 - 6 As shown, the limit component 17 includes a mounting plate 171 fixedly installed on the mounting frame 15, a side plate 172 connected to the mounting plate 171, and a clamping block 173 connected to the side plate 172. The clamping block 173 is clamped inside the card slot 16, and the side of the clamping block 173 facing the middle of the mounting frame 15 is arc-shaped. When the seat cushion 1 drives the slider 18 to slide on the mounting frame 15, the slider 18 will abut against the end of the clamping block 173 extending out of the card slot 16. The slider 18 with kinetic energy will squeeze the clamping block 173 into the card slot 16 through the arc-shaped side of the clamping block 173, and the clamping block 173 forces the side plate 172 to deform. When the slider 18 slides past the clamping block 173, the side plate 172 resets to drive the clamping block 173 to extend out of the card slot 16 again, and the straight side of the clamping block 173 will abut against the slider 18 to prevent the slider 18 from sliding back, so that the position of the seat cushion 1 stays at the end of the mounting frame 15 away from the impact.

[0020] An outer cylinder 174 is connected to the mounting plate 171. A T-shaped rod 175 is slidably connected to the end of the outer cylinder 174. The end of the T-shaped rod 175 abuts against the inner wall of the side plate 172. A spring 176 is sleeved on the T-shaped rod 175. One end of the spring 176 abuts against the inner wall of the T-shaped rod 175, and the other end abuts against the inner wall of the outer cylinder 174. An air cavity is provided between the inner wall of the outer cylinder 174 and the end of the T-shaped rod 175. The innermost clamping block 173 abuts against the slider 18.

[0021] As described above, when no gas enters the air chamber, the T-shaped rod 175 is only subjected to the force of the spring 176. At this time, the T-shaped rod 175 is located inside the outer cylinder 174, and the end of the T-shaped rod 175 is clamped between the two side plates 172, preventing the side plates 172 from bending inward and deforming. Furthermore, the clamping block 173 is stably clamped in the card slot 16, thereby restricting the sliding of the slider 18 and preventing the slider 18 from sliding when not impacted, maintaining the stable position of the seat cushion 1. When the vehicle is impacted, the air chamber is inflated, and the gas drives the T-shaped rod 175 to slide and compress the spring 176. The sliding T-shaped rod 175 disengages from the contact with the side plate 172, enabling the side plate 172 to deform after the clamping block 173 is stressed, facilitating the sliding of the slider 18 on the mounting frame 15. The end of the side plate 172 is provided with a gradually changing bevel edge. After the slider 18 slides past the clamping block 173, the air chamber deflates, and the compressed spring 176 resets and drives the T-shaped rod 175 to slide. The end of the T-shaped rod 175 slides past the gradually changing bevel edge of the side plate 172 and returns between the side plates 172, stably restricting the position of the clamping block 173 and preventing the slider 18 from sliding back.

[0022] Please refer to Figures 3 - 4 As shown, a four-way pipe block 11 is fixedly connected to the mounting base 4. An air delivery pipe 10 is connected between the four-way pipe block 11 and the airbag 9. Electrically controlled on-off valves 12 are respectively connected to both sides of the four-way pipe block 11. A guide pipe 13 is connected between each electrically controlled on-off valve 12 and the mounting frame 15. The end of the guide pipe 13 communicates with the air chamber.

[0023] As described above, after the vehicle is impacted, the electrically controlled on-off valve 12 on the side away from the vehicle impact opens. The gravity of the seat cushion 1 and the occupant presses down on the bracket telescopic cylinder 8, causing the bracket telescopic cylinder 8 to compress the airbag 9. The gas in the airbag 9 is transmitted to the four-way pipe block 11 through the air delivery pipe 10, and then to the air chamber through the four-way pipe block 11, the electrically controlled on-off valve 12, and the guide pipe 13, thereby triggering the limit assembly 17. Taking the vehicle impact as the trigger condition for the electrically controlled on-off valve 12, the relevant structure can adopt the existing structure. For example, the electrically controlled on-off valve 12 is set to be closed in the normal state and is powered on and opened after the vehicle is impacted as the trigger state. After the electrically controlled on-off valve 12 is triggered, it closes to discharge the gas in the airbag 9, causing the bracket telescopic cylinder 8 to contract and become shorter. While reducing the center of gravity of the seat cushion 1 and the occupant, the limit assembly 17 is triggered, causing the seat cushion 1 to slide and stop at a distance, enhancing the protection effect.

[0024] Embodiment 2:

[0025] Please refer to Figures 1 - 6 As shown, an anti-side-impact protection structure for an automobile seat includes: A seat cushion 1, a side support 2 and a backrest 3 are connected to the seat cushion 1. The side support 2 can provide a block for the legs of the occupant, preventing the occupant from sliding off the seat cushion 1. An installation base 4 is installed on a vehicle, and a plurality of bracket telescopic cylinders 8 with their upper ends abutted against the seat cushion 1 are connected to the installation base 4. An airbag 9 is arranged inside the bracket telescopic cylinder 8. The airbag 9 is in an inflated state when the vehicle is not impacted. The airbag 9 is provided with a triggering component. When the vehicle is impacted, the triggering component starts to release the gas in the airbag 9, so that the seat cushion 1 moves downward, reducing the center of gravity of the occupant and increasing the activity space of the occupant, preventing the occupant from being stuck inside the passenger compartment. A connecting rod 14 is connected between two bracket telescopic cylinders 8 on the same side. An installation frame 15 is fixedly connected to the connecting rod 14. A plurality of card slots 16 are formed in the installation frame 15. A limiting component 17 clamped in the card slots 16 is connected to the installation frame 15. A slider 18 slidably connected to the installation frame 15 is connected to the seat cushion 1.

[0026] As can be seen from the above, when the vehicle is impacted on the side, the vehicle impact information is used as a triggering condition to trigger the limiting component 17, so that the limiting component 17 far from the side of the vehicle impacted is triggered. At the same time, the impact kinetic energy received by the vehicle will be transmitted to the seat cushion 1. The seat cushion 1 that absorbs the kinetic energy drives the slider 18 to slide on the installation frame 15, so that the seat cushion 1 moves away from the side of the vehicle impacted. When the slider 18 slides to the farthest end of the installation frame 15, the limiting component 17 at the farthest end will block the slider 18 to prevent the slider 18 from rebounding, so that the seat cushion 1 stops sliding at the farthest end of the installation frame 15, thereby making the occupant on the seat cushion 1 stay on the side far from the vehicle impact source and reducing the harm caused by the vehicle impact to the occupant on the seat cushion 1.

[0027] Please refer to Figures 3 - 6 As shown, the limiting component 17 includes a mounting plate 171 fixedly installed on the installation frame 15, a side plate 172 connected to the mounting plate 171, and a clamping block 173 connected to the side plate 172. The clamping block 173 is clamped inside the card slot 16, and the side of the clamping block 173 facing the middle of the installation frame 15 is arc-shaped. When the seat cushion 1 drives the slider 18 to slide on the installation frame 15, the slider 18 will abut against the end of the clamping block 173 extending out of the card slot 16. The slider 18 with kinetic energy will squeeze the clamping block 173 into the card slot 16 through the arc-shaped side surface of the clamping block 173. The clamping block 173 forces the side plate 172 to deform. When the slider 18 slides past the clamping block 173, the side plate 172 resets to drive the clamping block 173 to extend out of the card slot 16 again. The straight side surface of the clamping block 173 will abut against the slider 18 to prevent the slider 18 from sliding back, so that the position of the seat cushion 1 stays at the end of the installation frame 15 far from the impact.

[0028] An outer cylinder 174 is connected to the mounting plate 171. A T-shaped rod 175 is slidably connected to the end of the outer cylinder 174. The end of the T-shaped rod 175 abuts against the inner wall of the side plate 172. A spring 176 is sleeved on the T-shaped rod 175. One end of the spring 176 abuts against the inner wall of the T-shaped rod 175, and the other end abuts against the inner wall of the outer cylinder 174. An air cavity is provided between the inner wall of the outer cylinder 174 and the end of the T-shaped rod 175. The innermost clamping block 173 abuts against the slider 18.

[0029] As can be seen from the above, when no gas enters the air cavity, the T-shaped rod 175 is only affected by the spring 176. At this time, the T-shaped rod 175 is located inside the outer cylinder 174, and the end of the T-shaped rod 175 is clamped between the two side plates 172, preventing the side plates 172 from bending and deforming inward. Furthermore, the clamping block 173 is stably clamped inside the card slot 16, thereby restricting the sliding of the slider 18 and preventing the slider 18 from sliding when not being impacted, maintaining the stable position of the seat cushion 1. When the vehicle is impacted, the air cavity is inflated, and the gas drives the T-shaped rod 175 to slide and compress the spring 176. The sliding T-shaped rod 175 disengages from the contact with the side plate 172, enabling the side plate 172 to deform after the clamping block 173 is stressed, facilitating the sliding of the slider 18 on the mounting frame 15. A gradually changing bevel edge is provided at the end of the side plate 172. After the slider 18 slides past the clamping block 173, the air cavity deflates, and the compressed spring 176 resets to drive the T-shaped rod 175 to slide. The end of the T-shaped rod 175 slides past the gradually changing bevel edge of the side plate 172 and returns between the side plates 172, stably restricting the position of the clamping block 173 and preventing the slider 18 from sliding back.

[0030] Please refer to Figures 3 - 4 As shown, a four-way pipe block 11 is fixedly connected to the mounting base 4. An air delivery pipe 10 is connected between the four-way pipe block 11 and the airbag 9. Electrically operated opening and closing valves 12 are respectively connected to both sides of the four-way pipe block 11. A guide pipe 13 is connected between each electrically operated opening and closing valve 12 and the mounting frame 15. The end of the guide pipe 13 communicates with the air cavity.

[0031] As described above, when the vehicle is impacted, the electric opening and closing valve 12 on the side away from the vehicle impact opens. The gravity of the seat cushion 1 and the occupant presses down on the support telescopic cylinder 8, causing the support telescopic cylinder 8 to compress the airbag 9. The gas in the airbag 9 is transmitted through the air delivery pipe 10 to the four-way pipe block 11, and then to the air chamber via the four-way pipe block 11, the electric opening and closing valve 12, and the air guide pipe 13, thereby triggering the limit component 17. Taking the vehicle impact as the trigger condition for the electric opening and closing valve 12, the related structures can adopt existing structures. For example, the electric opening and closing valve 12 is set to be closed in the normal state and is powered off and opened when the vehicle is impacted as the trigger state. After the electric opening and closing valve 12 is triggered, the gas in the airbag 9 is discharged, causing the support telescopic cylinder 8 to contract and become shorter. While reducing the center of gravity of the seat cushion 1 and the occupant, the limit component 17 is triggered, causing the seat cushion 1 to slide and stop at a distance, enhancing the protection effect.

[0032] A sliding frame 5 is connected to the installation base 4. A sliding plate 6 arranged in an L shape is slidably connected inside the sliding frame 5. A support rod 7 is fixedly connected to the end of the sliding plate 6. The support rod 7 is inserted into the side support 2. When the position of the seat cushion 1 drops, the position of the support rod 7 remains unchanged. At this time, the support rod 7 will lift the side support 2 upward, increasing the height of the side support 2, so that the side support 2 can wrap the legs of the occupant over a larger area, preventing the occupant from detaching from the seat after being impacted and improving the safety of the occupant.

[0033] The side plate 172 is made of spring steel, which facilitates the deformation and reset of the side plate 172. And there is a gap between the straight side surface of the clamping block 173 and the clamping groove 16, which can provide a moving gap for the deformation of the side plate 172 and the displacement of the clamping block 173.
