Description

Technical Field

[0001] This utility model relates to the field of vehicle seat technology, specifically a pneumatic high-lift shock-absorbing seat. Background Technology

[0002] Currently, special vehicles require seats with complete functions, reliable mechanisms, convenient operation, and shock absorption for comfort. Due to the special needs of these vehicles, seat height needs to be adjusted during travel. However, the existing vehicle seat height adjustment range is small and not suitable for special vehicle seats. Utility Model Content

[0003] The present invention aims to provide a pneumatic high-lift shock-absorbing seat to solve the problems of existing vehicle seats having a small height adjustment range, not being able to adjust the height steplessly, and not being suitable for special vehicle seats.

[0004] To achieve the above objectives, the basic solution of this utility model is as follows: a pneumatic high-lift shock-absorbing seat, comprising a seat body, a mounting base plate, and a height adjustment assembly. The height adjustment assembly is installed below the seat body, and the mounting base plate is installed at the lower end of the height adjustment assembly. The height adjustment assembly includes an inner cylinder, an outer cylinder, a gas spring, an unlocking handle, a cable, a locking pin, a locking plate, a fixing plate, and a bracket plate. The inner cylinder is slidably connected inside the outer cylinder, the outer cylinder is fixed to the mounting base plate, and the gas spring is fixed inside both the inner and outer cylinders. The fixing plate is fixed to the top of the inner cylinder and is fixedly connected to the upper part of the gas spring. The bracket plate is fixed to the bottom of the inner cylinder. The unlocking handle is rotatably connected to the side wall of the inner cylinder. The locking pin is slidably connected to the bracket plate. The locking plate is fixed to the inner wall of the outer cylinder. The locking pin passes through the inner cylinder and can be inserted into the locking plate. The unlocking handle is provided with a rotating block. One end of the rotating block is fixed to the pull cable. The other end of the rotating block is located at the top of the gas spring and can press the gas spring switch. The two ends of the pull cable are respectively connected to the unlocking handle and the locking pin.

[0005] Furthermore, it also includes a shock absorption assembly, which is installed between the seat body and the height adjustment assembly. The shock absorption assembly includes an upper shock absorber, a lower shock absorber, a shock absorber spring, and a damper. The upper shock absorber is fixed to the bottom of the seat body, and the lower shock absorber is fixed to the top of the inner cylinder. The upper shock absorber is slidably connected inside the lower shock absorber. The shock absorber spring is fixed on the upper and lower shock absorbers. The damper is installed on the bottom surface of the lower shock absorber, and the top of the damper abuts against the top surface of the upper shock absorber.

[0006] Furthermore, the upper shock absorber is provided with a number of guide pins on its outer side, and the lower shock absorber is provided with a number of guide grooves on its side wall corresponding to the positions of the guide pins, and the number of guide pins are slidably connected in the guide grooves respectively.

[0007] Furthermore, a lubrication sleeve is provided between the inner cylinder and the outer cylinder.

[0008] Furthermore, a guide block is provided on the outer side of the inner cylinder, and a vertical strip groove is provided on the side wall of the outer cylinder, with the guide block slidably connected in the strip groove.

[0009] The beneficial effects of this solution are as follows: (1) When the unlocking handle is lifted, the unlocking handle drives the rotating block to move one end of the cable upward, and the other end presses down on the gas spring switch to unlock the gas spring. The cable is linked to the locking pin. When the locking pin exits the locking plate, the gas spring switch is also in the open state. By applying or releasing pressure to the seat body, the gas spring can be applied or released, thereby changing the length of the gas spring. This allows the inner cylinder to slide up and down in the outer cylinder. After adjusting to a suitable height, the unlocking handle is released, the rotating block stops pressing the gas spring switch, the gas spring is locked, and the seat body is locked at this height. The gas spring has a large compression stroke and is easy to extend and retract, realizing a wide range, fast and stable adjustment of the height of the seat body. If the gas spring fails and is not successfully locked, the locking pin falls into the nearest hole on the locking plate to realize the mechanical locking of the seat body and ensure the stability and safety of the people on the seat.

[0010] (2) When the vehicle is bumpy, the shock absorption components can dampen the seat body and improve the ride comfort. Attached Figure Description

Four guide pins 5 are provided on the outer side of the upper shock absorber 7, and four guide grooves corresponding to the positions of the guide pins 5 are provided on the side wall of the lower shock absorber 6. The guide pins 5 are slidably connected in the guide grooves. The damper 21 is installed on the bottom surface of the lower shock absorber 6, and the top of the damper 21 abuts against the top surface of the upper shock absorber 7.

[0019] The height adjustment assembly includes an inner cylinder 4, an outer cylinder 2, a gas spring 12, an unlocking handle 13, a cable 16, a locking pin 17, a locking plate 19, a fixing plate 14, a bracket plate 15, and a mounting plate 11. The top of the inner cylinder 4 is fixed to the lower shock absorber 6. The inner cylinder 4 is slidably connected inside the outer cylinder 2. A lubrication sleeve 10 is provided between the inner cylinder 4 and the outer cylinder 2. A guide block 3 is provided on the outer side of the inner cylinder 4. A vertical strip groove is provided on the side wall of the outer cylinder 2. The guide block 3 is slidably connected inside the strip groove. The outer cylinder 2 is fixed on the mounting base plate 1, and the mounting plate 11 is fixed to the bottom of the outer cylinder 2. The gas spring 12 is fixed on the mounting plate 11, and the gas spring 12 is located inside the inner cylinder 4 and the outer cylinder 2. The fixing plate 14 is fixed on the top of the inner cylinder 4, and the fixing plate 14 is fixedly connected to the upper part of the gas spring 12. The bracket plate 15 is fixed on the bottom of the inner cylinder 4. The unlocking handle 13 is rotatably connected to the side wall of the inner cylinder 4. The locking pin 17 is slidably connected to the bracket plate 15. The locking plate 19 is fixed on the inner wall of the outer cylinder 2. The locking pin 17 passes through the inner cylinder 4 and can be inserted into the locking plate 19. The inner wall of the inner cylinder 4 is provided with a guide that is slidably connected to the outside of the locking pin 17.
