[0003] When the existing test devices on the market perform internal simulation, they can only perform a single simulation form of a ramp and a plane. However, the actual road conditions are generally much more complex. Therefore, when the test device performs a passability test, the slope of the test ramp is often too single, which thus affects the passability test. For example, in the test method disclosed in a new energy vehicle passability experiment driving environment vegetable dynamic simulation system with the application number 202010844509.X, although it is provided with forms of a plane and a pit, the depression degree of its pit is fixed, so it cannot perform diverse passability tests, making the data obtained after the detection by the entire detection device too limited and not representative;

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-5 , the present invention provides a technical solution: an automobile passing performance detection device, including a device fixing seat 1, the cross section of which is arranged in a "U" - shaped structure for supporting the whole device;

[0032] A ramp test main body 2, which is inside the device fixing seat 1 for detecting the passing of an automobile through a ramp;

[0033] A placing plate 9, which is arranged in a rectangular flat plate structure and has the same cross - sectional dimensions as the top - view cross - section of the device fixing seat 1 for directly placing above the device fixing seat 1 to detect the passing of an automobile through a plane;

[0034] It further includes;

[0035] An auxiliary moving mechanism, which includes an auxiliary downhill 4 and an auxiliary uphill 3. The auxiliary downhill 4 and the auxiliary uphill 3 are respectively arranged on both sides of the device fixing seat 1 and are both connected to the device fixing seat 1 through a tensile mechanism 6;

[0036] A buffer mechanism 5, which is arranged at the top of the auxiliary downhill 4 for quickly buffering and stopping the vehicle. The buffer mechanism 5 is a rotating structure at the top of the auxiliary downhill 4 for folding and storing;

[0037] The present application provides an automobile passing performance detection device with an auxiliary moving mechanism and a buffer mechanism 5. Specifically, when in use, first, the entire device is fixed in a suitable position under the action of the device fixing seat 1. Then, according to the type of vehicle test required, it is selected whether to perform a plane test above the placement plate 9 or a slope test on the top of the ramp test body 2. After the selection is completed, the vehicle is controlled to perform an auxiliary ascending operation through the auxiliary uphill 3. Then, it reaches the top of the placement plate 9 or the ramp test body 2 to perform the detection work. After that, it drives out through the auxiliary downhill 4. Then, the vehicle reaches above the buffer mechanism 5 to perform the buffering work, so that the vehicle can quickly buffer and stop without the need for a long-distance stopping and braking operation.

[0038] As a further preference of this embodiment, according to Figures 2-5 As shown, the inside of the device fixing seat 1 is of a hollow structure, and reserved grooves 11 are provided on both sides thereof. A stretching mechanism 6 is arranged inside the reserved grooves 11 for connecting with the auxiliary moving mechanism.

[0039] The ramp test body 2 is composed of 2 test ramps. The test ramp includes a moving seat 21, a concave ramp 22, a lifting mechanism 23 and a convex ramp 24. The concave ramp 22 and the convex ramp 24 are alternately arranged at the top of the moving seat 21. The outside of the convex ramp 24 is integrally installed with the moving seat 21, and the bottom of the concave ramp 22 is integrally installed with the bottom of the moving seat 21 through the lifting mechanism 23.

[0040] A moving mechanism 7 is arranged on the outside of the test ramp, and it includes a lead screw 71, a rotating sleeve 72 and a lifting mechanism 73. The outside of the rotating sleeve 72 is integrally installed with the outside of the moving seat 21, and the lead screw 71 is threadedly connected inside it. The top of the lead screw 71 is connected to a servo motor 8;

[0041] A lifting mechanism 23 is arranged at the bottom of the moving seat 21 for performing the up and down movement of the moving seat 21. The lifting mechanism 23 can be any one of an automatic telescopic rod or a cylinder;

[0042] Sliders are arranged on the outside of the servo motor 8 to slide in the chute on the side wall of the device fixing seat 1, and sliders are also arranged at the bottom of the lifting mechanism 23 to slide in the chute at the bottom of the device fixing seat 1;

[0043] The stretching mechanism 6 includes a limiting rod 61 and a compression spring 62. The outside of the limiting rod 61 is connected to the inside of the auxiliary moving mechanism, and the inner top of the limiting rod 61 is connected to the inner wall of the reserved groove 11 through the compression spring 62;

[0044] Specifically, when performing ramp driving detection, first, the placement plate 9 needs to be removed from the top of the device fixing seat 1. After that, the lifting mechanism 73 at the bottom of the moving mechanism 7 is started. The lifting mechanism 73 can be any one of a telescopic cylinder or an automatic telescopic rod, so that it drives the test ramp at its top to move upward, and when its height is higher than the top of the device fixing seat 1, the ramp detection work can be carried out.

[0045] When detecting the ramp and it is necessary to control the inclination angle of the ramp, at this time, the lifting mechanism 23 needs to be started, so that it drives the sunken ramp 22 at its top to move upward, thus making the distance between the sunken ramp 22 and the protruding ramp 24 smaller, and thus the inclination angle of the ramp is adjusted, and thus the detection work can be carried out again;

[0046] When it is necessary to change the position of the ramp, at this time, the servo motor 8 at the top of the moving mechanism 7 needs to be started, so that it drives the lead screw 71 at its top to rotate. When the lead screw 71 rotates, it is threadedly connected with the rotating sleeve 72, so that the rotating sleeve 72 drives the moving seat 21 at its top to move back and forth. When it moves back and forth, the top of the moving seat 21 will squeeze the inside of the auxiliary moving mechanism, so that its movement drives the limiting rod 61 to move inside the reserved groove 11, pulling the compression spring 62 to deform, so that the position of the auxiliary moving mechanism can move with the movement of the ramp position, so that the bending positions on the two test ramps are staggered, thus facilitating the vehicle to perform the ramp detection work again.

[0047] As a further preference of this embodiment, according to Figures 1-2 As shown, the buffer mechanism 5 includes a rotating plate 51, a rotating shaft 52 and a buffer tire 53. The top of the rotating plate 51 is connected to the bottom of the auxiliary downhill 4 through the rotating shaft 52, and a buffer tire 53 is arranged at the middle position of the top of the rotating plate 51;

[0048] A groove is arranged in the middle of the auxiliary downhill 4 for engaging with the buffer tire 53 to achieve the effect of engaging and storing the buffer tire 53.

[0049] Specifically, when the vehicle drives out of the auxiliary downhill 4, it will reach above the placement plate 9. Since the buffer tire 53 is arranged at the top of the placement plate 9, it can quickly buffer the front of the car, so that the vehicle can decelerate and stop, and then control the vehicle to change direction and drive out slowly.

[0050] After the entire detection device has completed the detection, the rotating plate 51 can be pulled to rotate on the rotating shaft 52. Then, the rotating plate 51 is made to fit against the auxiliary downhill slope 4. At this time, the buffer tire 53 just engages in the groove at the top of the auxiliary downhill slope 4, completing the storage work. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0051] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
