Description
Technical Field

[0002] The number of cars owned is increasing, and the functions of cars are also increasing.

[0038] like Figure 3 and Figure 4As shown, the conveyor belt 402, the first combination wheel 404 and the second combination wheel 405 are suspended on the base 401 through the support rod.

[0039] In a preferred embodiment, a first space is formed inside the conveyor belt 402, and shells 403 are respectively provided on both sides of the conveyor belt 402 along the first direction, a lever 407 is connected between the two shells 403, and there is a gap between the shells 403 and the conveyor belt 402; a support column is also provided on the base 401, and the support rod and the support column are both located at the gap, the support column extends along the third direction and the free end of the support column is fixedly connected to a connecting plate 408, and the connecting plate 408 is located in the first space; a support rod 409 extending along the second direction is provided on the connecting plate 408, and the free end of the support rod 409 is rotatably connected to the lever 407; a lifting mechanism 410 is also provided on the connecting plate 408, and the lifting mechanism 410 is used to drive the lever 407 to rotate around the support rod 409.
[0040] like Figure 4 and Figure 5As shown, when in use, the shooting platform is set above the road simulation component 4, and the left bottom cross bar 101 and the right bottom cross bar 102 are respectively located on the two shells 403. When the lifting mechanism 410 drives the lever 407 to rotate around the support rod 409, the two shells 403 respectively follow the two ends of the lever 407 to rise / fall, so that the shooting platform can be tilted as a whole; in this embodiment, the two ends of the lever 407 and the two shells 403 can be fixedly connected to simulate the state of the vehicle being on an inclined road condition.

The friction between the contact surfaces and the friction between the two ends of the lever 407 and the contact surfaces of the shells 403 on both sides can keep the shells 403 balanced in the initial state; when the lifting mechanism 410 drives the lever 407 to rotate around the support rod 409, the two shells 403 rise / fall following the two ends of the lever 407, and the roller slides toward the side of the through groove away from the support rod 409 while rotating relative to the lever 407. Since the rotation angle of the lever 407 is about 10° and the two ends of the lever 407 are always in contact with the two shells 403 respectively, the two shells 403 can only be displaced in the vertical direction in a balanced state, forming a straight up and down movement, so that the shooting platform is tilted as a whole, which can realize the state of simulating a vehicle on an inclined road condition.
[0042] In a preferred embodiment, the lifting mechanism 410 includes a slide rail 4101 extending along the third direction, and fixed plates 4102 are provided at both ends of the slide rail 4101; a screw rod 4103 is rotatably connected between the two fixed plates 4102, and a third motor 4104 is provided on the fixed plate 4102 away from the connecting plate 408, and a driving shaft of the third motor 4104 is connected to one end of the screw rod 4103; a slider 4105 is provided on the slide rail 4101, and the screw rod 4103 penetrates the slider 4105 and is threadedly connected to the slider 4105; a slide rod 411 is connected to the end of the slider 4105 away from the slide rail 4101, and the slide rod 411 is movably connected to the lever 407, and when the slider 4105 slides along the slide rail 4101, the slide rod 411 can drive the lever 407 to rotate around the support rod 409.
[0043] like Figure 6 As shown, when the driving shaft of the third motor 4104 drives the screw rod 4103 to rotate around its own axis, the slider 4105 and the screw rod 4103 generate an interaction force due to the threaded connection, so that the slider 4105 slides along the third direction on the slide rail 4101, and at the same time, the slider 4105 can drive the lever 407 to rotate around the support rod 409 through the slide rod 411.
[0044] In a preferred embodiment, the sliding rod 411 includes a first sub-rod and a second sub-rod that are connected to each other, the first sub-rod extends along the second direction and is connected to the sliding block 4105, the second sub-rod extends along the third direction and is provided with a rotating shaft that passes through the second sub-rod along the second direction, and the rotating shaft is rotatably connected to the second sub-rod; the lever 407 is provided with a rectangular through hole, and the inner periphery of the through hole is provided with a slideway extending along its own length direction, the free end of the second sub-rod is connected to a ball head 412 after passing through the through hole, and the rotating shaft is slidably connected to the lever 407 through the slideway.
[0045] like Figure 4 As shown, when the lever 407 rotates around the support rod 409 driven by the lifting mechanism 410, the rotating shaft slides along the length direction of the lever 407 toward the side of the through hole away from the support rod 409, and at the same time, the rotating shaft and the second sub-rod rotate relatively, so that the second sub-rod can move along the third direction while driving the lever 407 to rotate around the support rod 409; when the second sub-rod rises along the third direction, the ball head 412 can form a bulge on the surface of the conveyor belt 402, and the height of the bulge formed on the surface of the conveyor belt 402 can be determined according to the infrared rays generated by the infrared generator received by the infrared receiver.
[0046] The present application sets the lifting mechanism 410 and the lever 407 in the road simulation component 4, so that the road simulation component 4 can simulate different road conditions at the same time, meet the requirements of the shooting platform for vehicle model simulation testing on inclined road conditions and raised road conditions, and improve the applicability of the test device. By setting cameras 304 on each of the crossbars 3 of the shooting platform, images of reference objects around the shooting platform when it is located in different road conditions can be captured during the test, and relevant data of the vehicle test can be collected.
