Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle seats, and particularly relates to a shock-absorbing structure for a vehicle seat. Background Art

[0002] When a vehicle is in motion, it will encounter various road conditions, such as bumps and potholes, which will cause the vehicle body to vibrate, thereby affecting the passengers on the seat. The shock absorption of the vehicle seat can absorb these vibrations and reduce the impact on the passengers' bodies, improving the riding comfort and safety.

[0003] The existing shock absorption of vehicle seats often uses the method of a spring plus an unadjustable hydraulic damper for shock absorption, which only has a good shock absorption effect on vibrations of some amplitudes. When the vibration amplitude changes greatly, the shock absorption control is poor, and the seat displacement is large, affecting the riding experience of passengers. Therefore, a new type of shock-absorbing structure for vehicle seats is needed. Summary of the Utility Model

[0004] To solve the above problems, the utility model discloses a shock-absorbing structure for a vehicle seat.

[0005] To achieve the above object, the technical solution of the utility model is as follows:

[0006] A shock-absorbing structure for a vehicle seat, including a seat cushion. The bottom of the seat cushion is elastically connected with a connecting plate. A piston plate is fixedly connected to the square column at the bottom of the connecting plate, and a hydraulic damping shell is sleeved outside the piston plate. The bottom of the piston plate is fixedly connected with a plurality of shock-absorbing springs, and the bottom of each shock-absorbing spring is fixedly connected to the inner cavity bottom wall of the hydraulic damping shell. A slit hole is respectively opened at the top and bottom of each side wall of the hydraulic damping shell. Each side wall of the hydraulic damping shell is fixedly connected with a connecting shell, and the top and bottom of each connecting shell are respectively communicated with the adjacent slit holes. An installation plate is embedded in the inner cavity of each connecting shell, and the installation plate divides the inner cavity of the connecting shell into upper and lower parts. A plurality of elastic flow rings are embedded in each installation plate.

[0007] As a preferred technical solution of the utility model, the thickness of the elastic flow ring gradually decreases from the outer edge to its own center.

[0008] As a preferred technical solution of the utility model, a plurality of movable columns are fixedly connected to the upper surface of the connecting plate, and each movable column is slidably connected to the seat cushion. An inflated air cushion is sandwiched between the seat cushion and the connecting plate.

[0009] As a preferred technical solution of the utility model, a circular plate-shaped protrusion is arranged at the top of each movable column, and an auxiliary spring is connected to the top and bottom surfaces of each circular plate-shaped protrusion. One end of each auxiliary spring away from the circular plate-shaped protrusion is connected to the seat cushion.

[0010] As a preferred technical solution of the present utility model, a plurality of fixing seats are fixedly installed at the bottom of the seat, and each fixing seat is provided with a vertical through hole.

[0011] As a preferred technical solution of the present utility model, a rotating seat is fixedly connected to one side of the seat, and the rotating seat is rotatably connected to a backrest.

[0012] As a preferred technical solution of the present utility model, a seat cushion is connected to the upper surface of the seat, and a headrest and a backrest are sequentially installed on the side of the backrest facing the passenger from top to bottom.

[0013] The beneficial effects of the present utility model are as follows:

[0014] First, when the vibration of the vehicle body is transmitted to the hydraulic damping shell, the liquid above and below the piston plate flows through the communication shell to consume the vibration energy. Since the vibration amplitudes are different, the flow rates through the central through hole of the elastic flow ring are different, and the aperture of the central through hole of the elastic flow ring changes with the flow rate, making the hydraulic damping variable, facilitating adaptation to vibrations of different amplitudes, quickly consuming the vibration energy, and suppressing the transmission of vibrations. Thanks to the setting of the variable hydraulic damping, the damping structure has a good damping effect on vibrations of different amplitudes, and the damping structure provides a large liquid flow cavity with a relatively thin overall thickness, which is conducive to energy consumption;

[0015] Second, the seat and the connecting plate are slidably inserted through the movable columns, and the air cushion at the top of the connecting plate jacks up the seat. Thanks to the air cushion isolating most of the fine vibrations transmitted from the connecting plate to the seat, the riding comfort is further improved. Description of the Drawings

[0024] The following further clarifies the present utility model in conjunction with the drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0025] Please refer to Figures 1-6 , an automobile seat shock-absorbing structure, including a seat 1, a rotating seat 13 is fixedly connected to one side of the seat 1, and a backrest 14 is rotatably connected to the rotating seat 13. A cushion 15 is connected to the upper surface of the seat 1, and both sides of the cushion 15 extend upward to provide a certain lateral support for passengers. A headrest 17 and a back pad 16 are sequentially installed on the side of the backrest 14 facing the passengers from top to bottom. The back pad 16 is provided with a lumbar protrusion, and lateral extensions are provided on both sides of the lumbar protrusion.

[0026] The bottom of the seat 1 is elastically connected to a connecting plate 2. A piston plate 7 is fixedly connected to the square column at the bottom of the connecting plate 2, and a hydraulic damping shell 6 is sleeved outside the piston plate 7. A through hole adapted to the square column at the bottom of the connecting plate 2 is provided at the top of the hydraulic damping shell 6. A plurality of shock-absorbing springs 8 are fixedly connected to the bottom of the piston plate 7, and the bottom of each shock-absorbing spring 8 is fixedly connected to the inner cavity bottom wall of the hydraulic damping shell 6. The plurality of shock-absorbing springs 8 jointly push up the piston plate 7. A slit hole 601 is respectively opened at the top and bottom of each side wall of the hydraulic damping shell 6. A connecting shell 9 is fixedly connected to each side wall of the hydraulic damping shell 6, and the top and bottom of each connecting shell 9 are respectively communicated with the adjacent slit holes 601. A mounting plate 10 is embedded in the inner cavity of each connecting shell 9, and the mounting plate 10 divides the inner cavity of the connecting shell 9 into upper and lower parts. A plurality of elastic flow rings 11 are embedded in each mounting plate 10. The thickness of the elastic flow ring 11 gradually decreases from the outer edge to its own center. The elastic flow ring 11 is made of rubber material. Since the center through hole of the elastic flow ring 11 is thin and soft, as the flow rate through the center through hole of the elastic flow ring 11 increases, the aperture of the center through hole also increases accordingly, so as to enhance the liquid flow rate of the hydraulic damping shell 6, quickly consume the vibration energy in a short time, adapt to larger bumps and vibrations, and suppress the further transmission of vibrations.

[0027] To optimize the overall thickness of the shock-absorbing structure, the piston plate 7 has a relatively thin thickness. Since the piston plate 7 is relatively thin, if an elastic flow ring 11 is installed by opening a hole in the piston plate 7, the strength of the piston plate 7 will be further reduced, affecting the service life of the piston plate 7. By opening a hole in the side wall and using the connecting shell 9 to connect the holes, the strength of the piston plate 7 can be ensured.

[0028] A plurality of movable columns 3 are fixedly connected to the upper surface of the connecting plate 2, and each movable column 3 is slidably connected to the seat 1. A circular plate-shaped protrusion is provided at the top of each movable column 3, and an auxiliary spring 4 is connected to the top surface and the bottom surface of each circular plate-shaped protrusion. One end of each auxiliary spring 4 away from the circular plate-shaped protrusion is connected to the seat 1. An inflated air cushion 5 is sandwiched between the seat 1 and the connecting plate 2. A valve for inflating and deflating is provided on the branch pipe on the side of the air cushion 5. The auxiliary spring 4 only assists the sliding between the movable column 3 and the seat 1, and the air cushion 5 jacks up the seat 1 upward.

[0029] A plurality of fixing seats 12 are fixedly installed at the bottom of the seat 1, and each fixing seat 12 is provided with a vertical through hole. The through holes of the fixing seats 12 are used for bolts to pass through and be fixedly connected to the slide rail of the vehicle seat, so as to install the seat 1 on the vehicle seat slide rail.

[0030] Working principle:

[0031] When a passenger sits on the seat 1, the vibration of the vehicle body is transmitted to the hydraulic damping shell 6, causing the hydraulic damping shell 6 to move up and down relative to the piston plate 7. At this time, the liquid above and below the piston plate 7 flows through the connecting shell 9 to consume the energy of the vibration. Due to the different amplitudes of the vibration, the flow rates through the central through hole of the elastic flow ring 11 are different, and the aperture of the central through hole of the elastic flow ring 11 changes with the flow rate, making the hydraulic damping variable, facilitating adaptation to vibrations of different amplitudes, quickly consuming the energy of the vibration, and suppressing the transmission of the vibration;

[0032] The seat 1 and the connecting plate 2 are slidably inserted through the movable column 3, and the air cushion 5 at the top of the connecting plate 2 jacks up the seat 1 upward, so that the air cushion 5 can isolate most of the fine vibrations transmitted from the connecting plate 2 to the seat 1, and cooperate with the cushion 15 on the seat 1 to enhance the riding comfort of the seat 1.

[0033] It should be noted that the above content only illustrates the technical idea of the present invention and cannot be used to limit the protection scope of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches all fall within the protection scope of the claims of the present invention.
