Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery equipment and vehicle seats, specifically relating to a seat base suitable for air-suspended seats. Background Technology

[0002] Construction machinery and vehicles are mostly used on unpaved roads. When operating or driving on such unpaved roads, construction machinery and vehicles experience greater bumps, which reduces the comfort of drivers and passengers. Currently, almost all construction machinery vehicles use air suspension seats to improve driving comfort.

[0003] The seating height varies for drivers and passengers of different heights. The height adjustment of the air suspension seat relies on the inflation and deflation of the airbags in the seat. When the airbags inflate, the seat height is raised, and when they deflate, the seat height is lowered. According to multiple tests and actual test results, the shock absorption performance is best when the airbags are inflated to about the middle position. Over-inflation or under-inflation will cause the seat to lose most of its shock absorption performance, thus affecting the comfort of the drivers and passengers. Utility Model Content

[0004] The purpose of this invention is to provide a seat base suitable for air-suspended seats, which solves the problem of reduced driving comfort caused by weakened seat shock absorption performance when the airbags of air-suspended seats are over- or under-inflated, and improves the driving comfort of mining truck seats.

[0005] The technical solution is as follows:

[0006] A seat base suitable for an air-suspended seat includes: a top plate assembly, a bottom plate assembly, and fastening screws. The top plate assembly includes: a top plate and a top plate sleeve. The top plate sleeve is connected to the bottom of the top plate, and the side of the top plate sleeve has multiple top plate sleeve through holes. The bottom plate assembly includes: a bottom plate and a bottom plate sleeve. The bottom plate sleeve is connected to the top of the bottom plate, and the side of the bottom plate sleeve has a bottom plate sleeve through hole with an end head and an end head threaded hole. The top plate sleeve is inserted into the bottom plate sleeve, and the fastening screws are connected to the end head threaded holes, with the front end of the fastening screws passing through the top plate sleeve through holes.

[0007] Furthermore, the top plate has multiple top plate connection through holes at its edge, and the top plate connection through holes are fitted with first connecting screws; the bottom plate has multiple bottom plate connection through holes at its edge, and the bottom plate connection through holes are fitted with second connecting screws.

[0008] Furthermore, the top and bottom plates are made of rectangular steel plates, with connecting through holes in the top plate located at the four corners, and connecting through holes in the bottom plate located at the four corners.

[0009] Furthermore, the top plate sleeve is made of rectangular tube, and multiple top plate sleeve through holes are provided on three sides of the top plate sleeve; the bottom plate sleeve is made of rectangular tube, and bottom plate sleeve through holes are provided on three sides of the bottom plate sleeve.

[0010] Furthermore, the top plate sleeve through hole is a tapered hole, the bottom plate connection through hole is a long through hole, and the front end of the fastening screw is tapered.

[0011] Furthermore, the top plate and the rectangular tube are welded together, and the bottom plate sleeve is welded to the top of the bottom plate.

[0012] Furthermore, the fastening screws are equipped with spring washers and flat washers.

[0013] This utility model has the following advantages compared with the prior art:

[0014] Existing seat bases are not height-adjustable and rely on air suspension airbags for height adjustment, sacrificing seat comfort. This application improves the driving and riding comfort of mining truck seats by adjusting the height of the base, making up for the common problem of air suspension seats and filling the gap of non-adjustable seat base height.

[0022] A seat base suitable for an air-suspended seat includes: a top plate assembly 1, a bottom plate assembly 2, and fastening screws 3; the top plate assembly 1 and the bottom plate assembly 2 are connected together by fastening screws 3.

[0023] The top plate assembly 1 includes: a top plate 11 and a top plate sleeve 12. The top plate sleeve 12 is connected to the bottom of the top plate 11. The side of the top plate sleeve 12 is provided with a top plate sleeve through hole 13. The top plate 11 is provided with a plurality of top plate connecting through holes 14 at its edge.

[0024] The top plate 11 is made of rectangular steel plate, and the top plate connecting through holes 14 are set at the four corners. The top plate connecting through holes 14 are equipped with first connecting screws, which connect to the bottom of the seat. The top plate sleeve 12 is made of rectangular tube, and the top plate 11 and the rectangular tube are welded together. The rectangular tube has multiple top plate sleeve through holes 13 on three sides, and the top plate sleeve through holes 13 are tapered holes.

[0025] The base plate assembly 2 includes a base plate 21 and a base plate sleeve 22, with the base plate sleeve 22 connected to the top of the base plate 21. The base plate 21 has multiple base plate connecting through holes 24 at its edge, and the base plate sleeve 22 has a base plate sleeve through hole on its side. Each base plate sleeve through hole has an end 23 with a threaded end hole, and a fastening screw 3 is installed in the threaded end hole. The top plate sleeve 12 is inserted into the base plate sleeve 22, and the fastening screw 3 is connected to the threaded end hole, with its front end passing through the top plate sleeve through hole 13. While connecting the top plate sleeve 12 and the base plate sleeve 22, the height between the top plate assembly 1 and the base plate assembly 2 can be adjusted through the multiple top plate sleeve through holes 13, thus achieving seat height adjustment.

[0026] The positions of the bottom plate sleeve through hole and the top plate sleeve through hole 13 are opposite.

[0027] The base plate 21 is made of rectangular steel plate, and the base plate connecting through holes 24 are located at the four corners. The base plate connecting through holes 24 are elongated through holes, which can be adjusted and fixed in position. The base plate connecting through holes 24 are equipped with second connecting screws, which are used to connect the base plate of the cockpit. The base plate sleeve 22 is made of rectangular tube and is welded to the top of the base plate 21. The rectangular tube has base plate sleeve through holes on three sides.

[0028] The top plate sleeve 12 and the bottom plate sleeve 22 are connected and positioned by fastening screws 3 on the three sides of the rectangular tube, which improves the connection strength of the top plate sleeve 12 and the bottom plate sleeve 22.

[0029] The top plate sleeve through hole 13 is a tapered hole, and the front end of the fastening screw 3 is tapered. The front end of the fastening screw 3 is inserted into the top plate sleeve through hole 13, which facilitates the positioning of the bottom plate sleeve through hole and the top plate sleeve through hole 13.

[0030] The fastening screw 3 is equipped with a spring washer and a flat washer to prevent the fastening screw 3 from loosening during use.

[0031] When installing the seat base, the second connecting screw is passed through the bottom plate connecting through hole 24 to connect the bottom plate 21 to the bottom plate of the cockpit (or it can be directly welded). The first connecting screw is passed through the top plate connecting through hole 14 to connect the top plate 11 to the bottom of the seat (or it can be directly welded). The top plate sleeve 12 is inserted into the bottom plate sleeve 22. The relative height of the bottom plate 21 and the top plate 11 is adjusted by aligning the end threaded hole with the different top plate sleeve through holes 13. The fastening screw 3 is connected in the end threaded hole, and the front end of the fastening screw 3 is inserted into the top plate sleeve through hole 13 to achieve the connection of the top plate assembly 1 and the bottom plate assembly 2, thereby fixing the seat to the bottom plate of the cockpit. By adjusting the relative height of the bottom plate 21 and the top plate 11, the airbag inflation pressure of the air suspension seat can be adjusted to the optimal state, improving seat comfort.
