[0035] In order to better understand the purpose, structure and function of the present invention, a spring hydraulic shock-absorbing seat of the present invention is further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 8 As shown, a spring hydraulic shock-absorbing seat includes a fixed frame 1, a seat frame 2, a seat 3, a hydraulic shock absorber 4 and a shock-absorbing spring 5. The fixed frame 1 includes an L-shaped first dorsal frame 11 and a first bottom side frame 12. Vertical slide grooves 13 are parallelly arranged on the left and right sides of the first dorsal frame 11. A lower connecting head 14 is fixedly arranged at the bottom of the first dorsal frame 11. The seat frame 2 includes an L-shaped second dorsal frame 21 and a second bottom side frame 22. At least two pairs of bearings 23 are arranged on the left and right sides of the second dorsal frame 21. The second dorsal frame 21 is connected to the first dorsal frame 11 in a rolling connection in the vertical slide groove 13 through the bearings 23. The seat 3 is installed on the second bottom side frame 12. An upper connecting head 24 is fixedly arranged on the top of the second dorsal frame 21. The upper connecting head 24 and the lower connecting head 14 are respectively connected to the two ends of the hydraulic shock absorber 4. A shock-absorbing spring 5 is sleeved on the outside of the hydraulic shock absorber 4. The two ends of the shock-absorbing spring 5 are respectively against the cylinder of the hydraulic shock absorber 4 and the end of the telescopic rod.

[0037] In this embodiment, the fixed frame 1 and the seat frame 2 are made of steel plates, angle irons and channel steels. The spring hydraulic shock-absorbing seat also includes a base 6, such as Figures 10 to 12 As shown, the base 6 includes a bottom plate 61 fixedly connected to the vehicle frame. Fixing tubes 62 are symmetrically arranged on the left and right sides of the bottom plate 61. Fastening bolts 63 are radially threadedly connected to the fixing tubes 62 and are located in the middle of the fixing tubes 62. The first bottom side frame 12 includes connecting tubes symmetrically arranged on the left and right sides. The connecting tubes can be inserted into the fixing tubes 62 and fastened with the fastening bolts 63.

[0038] like Figure 9 As shown, an annular plate 41 is circumferentially fixed on the cylinder of the hydraulic shock absorber 4 near the rear end of the cylinder, and one end of the shock absorbing spring 5 rests on the annular plate 41 .

[0039] like Figures 13 to 15As shown, during installation, first install the bottom plate 61 of the base 6 to the seat position in the cab of the rubber-wheeled vehicle and secure it with screws. Then, the combined frame of the fixed frame 1 and the seat frame 2 is fixed to the fixed tube 62 of the base 6 through the connecting tube and fastened with the fastening bolts 63 to ensure that the fixed frame 1 and the base 6 are effectively fixed and will not slide. Finally, a sponge leather seat is installed on the second bottom side frame 22 of the seat frame 2 and fixed with screws at the bottom. The driver can move the seat 3 forward and backward by adjusting the position of the fixed frame 1 according to his or her body size, and fix the seat 3 at different positions by fastening the bolts 63.

[0040] The spring hydraulic shock-absorbing seat of this embodiment has a seat frame 2 that can move up and down nested in the first dorsal frame 11 of the fixed frame 1, and the up and down movement is achieved by rolling on the bearing 23. A hydraulic shock absorber 4 and a shock-absorbing spring 5 are installed between the bottom of the fixed frame 1 and the top of the seat frame 2. When the vehicle passes through a bumpy road, the seat 3 slides up and down, converting the kinetic energy of the bumps into elastic potential energy of the spring, absorbing the kinetic energy of the bumps, and thus achieving the purpose of shock absorption.

[0041] The spring hydraulic shock-absorbing seat of this embodiment can achieve shock absorption for the seats of rubber-tyred trackless vehicles in coal mines. It has the characteristics of high safety factor, simple structure, and convenient use. During shock absorption, the vibration energy of the vehicle's bumps is converted to the hydraulic shock absorber 4 and shock-absorbing spring 5, converting kinetic energy into elastic potential energy, thereby reducing the discomfort caused by bumps and improving riding comfort.
