Description

Technical Field

[0001] This utility model relates to a shock-absorbing and comfortable forklift seat. Background Technology

[0002] When forklifts are in operation, especially outside of factories, they often have to travel on complex road surfaces, inevitably resulting in bumps. Existing forklift seats mainly rely on seat cushions for shock absorption, which is not very effective. Drivers in this environment for extended periods may experience difficulty concentrating. Therefore, it is necessary to design a shock-absorbing and comfortable forklift seat. Using shock absorbers would obviously improve the shock absorption performance of the forklift seat, but in reality, smaller shock absorbers cannot effectively support the driver sitting in the seat, while using larger shock absorbers installed at the bottom of the seat would make the seat too high. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a shock-absorbing and comfortable forklift seat, which overcomes the difficulty of applying large-sized shock absorbers to forklift seats.

[0004] The technical solution of this utility model is: a shock-absorbing comfort forklift seat, including a base and a seat mounted on the base, wherein an airbag is provided between the bottom of the seat and the base, and a shock-absorbing device is provided between the back of the seat and the base;

[0005] A support frame is fixed on each side of the seat. The support frame is triangular, with one corner connected to the side of the seat and a guide wheel rotatably connected to the other two corners of the support frame.

[0006] The shock absorption device includes two guide columns and a shock absorber;

[0007] The two guide columns are respectively fixed on the base on the back of the seat, and each of the two guide columns is provided with a guide groove. The two guide wheels of the two support frames are respectively slidably connected to the corresponding guide grooves.

[0008] The seat back and base are each provided with a connecting shaft, and the shock absorber is inclinedly disposed between the seat back and base, with its two ends respectively rotatably connected to the two connecting shafts.

[0009] Specifically, the guide grooves of the two guide posts are located on the inner side of the corresponding guide posts.

[0010] Furthermore, a connecting platform is provided at the rear end of the base, and a connecting shaft is provided on the connecting platform.

[0011] Furthermore, a rubber pad is fixed between the bottom of the seat and the top of the base, and arc-shaped mounting grooves for corresponding airbags are provided on the facing surfaces of the two rubber pads, with the upper and lower ends of the airbag of the airbag pad fixed in the corresponding arc-shaped mounting grooves.

[0012] Furthermore, a reinforcing ring is provided around the outer periphery of the airbag, and the reinforcing ring is horizontally positioned.

[0013] Furthermore, a bearing seat is provided in the middle of the back of the seat, and the two ends of the connecting shaft are respectively fixed on the bearing seat.

[0014] Furthermore, the base is provided with multiple fixing holes, and the base is fixed to the cab of the forklift by fixing bolts.

[0015] The beneficial effects of this utility model are as follows: This utility model mainly designs the position of the shock absorber, so that the seat can use a larger specification shock absorber, thereby obtaining a better shock absorption and support effect; when the forklift is bumpy during travel, the shock absorber first absorbs the shock, avoiding large-scale resonance of the seat. Under the combined action of the shock absorber, support frame and guide column, the seat only produces a small vertical displacement. Furthermore, because an airbag is set between the seat and the base, when the seat moves down, the airbag can buffer the impact of the seat moving down, making the vertical displacement of the seat gentler, thereby improving the comfort of the driver.

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Combination Figure 1 and Figure 2 As shown, a shock-absorbing comfort forklift seat includes a base 1 and a seat 2 disposed on the base 1. An airbag 3 is provided between the bottom of the seat 2 and the base 1, and a shock-absorbing device is provided between the back of the seat 2 and the base 1.

[0021] A support frame 4 is fixed on each side of the seat 2. The support frame 4 is triangular. One corner of the support frame 4 is connected to the side of the seat 2. A guide wheel 5 is rotatably connected to the other two corners of the support frame 4.

[0022] The shock absorption device includes two guide columns 6 and a shock absorber 7;

[0023] The two guide columns 6 are respectively fixed on the base 1 on the back of the seat 2, and the two guide columns 6 are respectively provided with guide grooves 8. The two guide wheels 5 of the two support frames 4 are respectively slidably connected to the corresponding guide grooves 8.

[0024] The back of the seat 2 and the base 1 are respectively provided with a connecting shaft 9. The shock absorber 7 is inclinedly arranged between the back of the seat 2 and the base 1, and its two ends are respectively rotatably connected to the two connecting shafts 9.

[0025] The above structure mainly focuses on the design of the shock absorber position, allowing the seat to use a larger shock absorber, thereby achieving better shock absorption and support. When the forklift experiences bumps during operation, the shock absorber 7 first absorbs the shock, preventing the seat 2 from experiencing large-scale resonance. Under the combined action of the shock absorber 7, support frame 4, and guide column 6, the seat 2 only experiences a small vertical displacement. Furthermore, since an airbag 3 is installed between the seat 2 and the base 1, when the seat 2 moves downward, the airbag 3 can buffer the impact of the seat 2 moving downward, making the vertical displacement of the seat 2 smoother, thereby improving the comfort of the driver.

[0026] In another embodiment, combined Figure 1 and Figure 2 As shown, the guide grooves 8 of the guide post 6 are located on the inner side of the guide post 6 to reduce the possibility of foreign objects entering the guide grooves 8.

[0027] In another embodiment, such as Figure 1 As shown, a connecting platform 10 is provided at the rear end of the base 1, and a connecting shaft 9 is provided on the connecting platform 10 to shorten the stroke of the shock absorber 7 and ensure the shock absorption effect.

[0028] In another embodiment, combined Figure 1 and Figure 2 As shown, a rubber pad 11 is fixed between the bottom of the seat 2 and the top of the base 1. The two rubber pads 11 are respectively provided with arc-shaped mounting grooves corresponding to the airbags 12 on their facing surfaces. The upper and lower ends of the airbags 12 of the airbag pad 3 are respectively fixed in the corresponding arc-shaped mounting grooves. When the seat 2 moves downward to a certain extent, the two rubber pads 11 abut against each other to avoid the airbags 12 from being over-stressed and breaking.

[0029] In another embodiment, combined Figure 1 and Figure 2As shown, a reinforcing ring 13 is also provided around the outer periphery of the airbag 12. The reinforcing ring 13 is horizontally arranged to ensure the reliability of the airbag 12.

[0030] In another embodiment, a bearing seat 14 is provided in the middle of the back of the seat 2, and the two ends of the connecting shaft 9 are respectively fixed on the bearing seat 14. With the arrangement of the two guide columns 6 and the two support frames 4, the seat 2 is subjected to uniform force when the shock absorber 7 is working.

[0031] In another embodiment, combined Figure 1 and Figure 2 As shown, the base 1 has multiple fixing holes, and the base 1 is fixed to the cab of the forklift by fixing bolts 15.

[0032] In another embodiment, such as Figure 1 As shown, a backrest adjuster 16 is also provided at the connection between the main body and the backrest of the seat 2. The specific structure of the backrest adjuster 16 is the same as that of the existing car backrest adjuster 16, and will not be described in detail here.
