[0029] See also Figure 1-Figure 6 , which shows a structural schematic diagram of a seat endurance test device of the utility model, please refer to Figure 1-Figure 6 , a seat endurance testing device is introduced in detail.

[0030] A seat endurance test device comprises a mounting frame 100, wherein a vertical mounting cylinder 120 is rotatably provided at the top center of the mounting frame 100 through a bearing sleeve 110, wherein the mounting cylinder 120 is in the shape of a cylinder with an open bottom wall, and a hollow platform 130 is fixedly provided at the top of the mounting cylinder 120, wherein the hollow platform 130 is in the shape of a hollow cylinder;

[0031] Above the top of the mounting bracket 100 is provided a fixing bracket 200 above the hollow table 130. The fixing bracket 200 is in the shape of a "冂". On the right side of the bottom of the fixing bracket 200 is fixedly installed a vertical fixing rod 210. The rod body of the fixing rod 210 penetrates through the top wall of the hollow table 130 with a gap, and at the bottom end of the fixing rod 210 is provided a linkage sector plate 220. The linkage sector plate 220 is semi-sector-shaped and has teeth 230 on the side close to the inner side wall of the hollow table 130. On the right inner side wall of the cavity of the hollow table 130, there protrudes an internal tooth 240 that meshes with the teeth 230. Both the teeth 230 and the internal tooth 240 are semi-circularly arranged around the fixing rod 210. Since the fixing rod 210 is not at the center of the hollow table 130, the internal tooth 240 is not completely arranged along the arc of the right inner side wall of the cavity of the hollow table 130, but is semi-circularly arranged around the fixing rod 210. On the side of the linkage sector plate 220 away from the teeth 230 is provided a linkage frame 250. The upper and lower walls of the linkage frame 250 are provided with sliding openings 260. Inside the sliding openings 260, a vertical sliding rod 270 is slidably arranged. On the left side of the top of the fixing bracket 200 is provided a vertical first servo motor 280. The output shaft of the first servo motor 280 rotates through the fixing bracket 200 and is connected to a vertical transmission rod 290 through a first coupling. The rod body of the transmission rod 290 penetrates through the top wall of the hollow table 130 with a gap. The bottom end of the transmission rod 290 is located inside the cavity of the hollow table 130 and is provided with a disc-shaped transmission disc 291. The upper end of the sliding rod 270 is rotatably located at a non-center position on the bottom wall of the transmission disc 291;

[0032] Inside the mounting cylinder 120, a vertical lifting column 300 is reciprocally lifted and lowered. The lower end of the lifting column 300 is located below the mounting cylinder 120 and is provided with a test plate 310.

[0033] Further, on the top of the hollow table 130, there is an opening one 140 for the rod body of the transmission rod 290 to move through with a gap, and on the top of the hollow table 130, there is an opening two 150 for the rod body of the fixing rod 210 to penetrate through with a gap. Both the opening one 140 and the opening two 150 are arc-shaped. When the first servo motor 280 drives the transmission rod 290 to rotate, it drives the sliding rod 270 to reciprocally slide along the sliding opening 260, causing the linkage frame 250 and the linkage sector plate 220 to rotate back and forth with the fixing rod 210 as the axis, and then through the teeth 230 and the internal tooth 240, the hollow table 130 rotates clockwise and counterclockwise reciprocally. Therefore, the opening one 140 and the opening two 150 are opened so that the transmission rod 290 and the fixing rod 210 will not interfere, and the hollow table 130 drives the test plate 310 to rotate.

[0034] Furthermore, a support plate 271 is protruded from the bottom of the slide rod 270, the diameter of the support plate 271 is larger than the width of the linkage frame 250, and the upper surface of the support plate 271 slides and fits with the lower edge of the linkage frame 250. The support plate 271 supports the bottom of the linkage frame 250, making the linkage frame 250 more stable when moving.

[0035] Furthermore, a second vertical servo motor 320 is fixedly arranged in the middle of the top wall of the inner cavity of the installation cylinder 120, and a vertical reciprocating screw rod 330 is connected to the output shaft of the second servo motor 320 through a first coupling. The shaft of the reciprocating screw rod 330 transmits and passes through the top of the lifting column 300. Vertical guide slide bars 340 are fixedly arranged on both sides of the top wall of the inner cavity of the installation cylinder 120, and the shaft of the guide slide bar 340 slides and passes through the top of the lifting column 300. When the second servo motor 320 drives the reciprocating screw rod 330 to rotate, the lifting column 300 will not rotate accordingly due to the limitation of the guide slide bar 340, but will move back and forth along the shafts of the reciprocating screw rod 330 and the guide slide bar 340.

[0036] Furthermore, an inlet and outlet 350 is provided at the lower end of the mounting tube 120 for the shaft of the lifting column 300 to pass through. The inner diameter of the inlet and outlet 350 is smaller than the inner diameter of the mounting tube 120. A limiting plate 360 ​​is provided at the upper end of the outer edge of the lifting column 300. When the lifting column 300 is lifted and lowered reciprocally, a gap is set between the lifting column 300 and the inlet and outlet 350, and no friction is generated between the two.

[0037] In the specific use process:

[0038] First, place the seat to be tested under the test board 310, with the seat surface located under the test board 310. There are two test modes:

[0039] The first method simulates a scenario in which a driver impacts the seat surface when sitting on the seat surface and when standing up, that is, the second servo motor 320 is started to drive the reciprocating screw rod 330 to rotate, so that the lifting column 300 moves back and forth along the rod body of the reciprocating screw rod 330 and the guide slide rod 340, driving the test plate 310 to repeatedly impact the seat surface;

[0040] The second method simulates the friction between the driver's buttocks and the seat surface when the driver sits on the seat and moves his body while driving, such as when the vehicle turns. The second servo motor 320 is first started to make the test plate 310 impact the seat surface, and then the second servo motor 320 is stopped to simulate the driver sitting on the seat surface. The first servo motor 280 is then started to drive the transmission rod 290 to rotate, and then the sliding rod 270 is driven to slide back and forth along the sliding mouth 260, so that the linkage frame 250 and the linkage fan-shaped plate 220 are driven to rotate back and forth with the fixed rod 210 as the axis, and then the hollow table 130 is driven to rotate clockwise and counterclockwise through the teeth 230 and the inner teeth 240, that is, the test plate 310 can be continuously driven to repeatedly rub the seat surface.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
