DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all, based on the embodiments in the embodiments, other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0028] As Figures 1-5 Indicated, the utility model provides a kind of automobile shock damping detection equipment, including at least one supporting plate 2, at least one vibration mechanism 3, elastic member 6 and distance sensor 10;

[0029] Supporting plate 2 is used to support the tire of automobile;

[0030] Each vibration mechanism 3 includes power assembly, first rotating shaft 36 and first supporting frame 37, first supporting frame 37 one end fixedly connected first rotating shaft 36, supporting plate 2 is located on first supporting frame 37, power assembly is used to drive first supporting frame 37 and supporting plate 2 around first rotating shaft 36 and do arc reciprocating swing;

[0031] Elastic member 6 one end is fixed to the bottom surface of supporting plate 2, when the height position of supporting plate 2 changes, elastic member 6 is in deformation state (the elastic member 6 here can adopt spring);

[0032] The distance sensor 10 is fixed to one side of the support plate 2, and is used to detect the change in the height position of the support plate 2 (the distance sensor 10 can be a resistance displacement sensor, and the specific working principle is prior art, which is not described here) ;

[0033] When the damping performance of the automobile needs to be detected, the automobile is driven to make the tire on the support plate 2, and then the automobile is stopped to make it no longer move. Then the power assembly is driven to make the power assembly drive the first support frame 37 and the support plate 2 to do arc reciprocating oscillation around the first rotating shaft 36. Then the power assembly is stopped, and under the action of inertia and the elastic member 6, the support plate 2 continues to do arc reciprocating oscillation around the first rotating shaft 36. At this time, the movement distance of the support plate 2 is detected by the distance sensor 10. When the movement distance of the support plate 2 is within the qualified range (the specific qualified range is the value set by the program, which is not described here), it indicates that the damping performance of the automobile is good. When it exceeds the qualified range, it indicates that the damping performance of the automobile is poor, and the shock absorber of the automobile needs to be repaired or replaced;

[0034] Through the device, the damping performance of the automobile can be tested after the shock absorber is installed on the automobile, and the detection effect is better and more accurate. At the same time, the damping performance of the shock absorber of the automobile in use can be detected at any time, avoiding the trouble of separately disassembling and detecting the shock absorber and subsequently installing it.

[0035] As shown in Figure 2 , Figure 3 and Figure 4 , the power assembly includes a motor 31, an eccentric wheel 32, a first connecting plate 33, a hinged seat 34, a second connecting plate 35, and a sleeve rod 38. The output end of the motor 31 is fixedly connected to the eccentric wheel 32. The eccentric wheel 32 is peripherally rotatably connected to the first connecting plate 33 through a bearing. One end of the first connecting plate 33 is hingedly connected to the hinged seat 34. One end of the hinged seat 34 is fixedly connected to the second connecting plate 35. One end of the second connecting plate 35 is fixedly connected to the sleeve rod 38. The sleeve rod 38 is fixedly connected to the first rotating shaft 36.

[0036] Specifically, the working principle of the power assembly is as follows: the motor 31 is started to drive the eccentric wheel 32 to rotate, which drives the first connecting plate 33 to eccentrically oscillate (mainly up and down, but not vertical up and down), and drives the hinged seat 34, the second connecting plate 35, the sleeve rod 38, and the first rotating shaft 36 to do arc reciprocating oscillation around the center line of the first rotating shaft 36, and finally drives the first support frame 37 and the support plate 2 to do arc reciprocating oscillation around the center line of the first rotating shaft 36.

[0037] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the shell 1 is provided with two through holes 101 in the top surface, the support plate 2 is movably arranged in the through hole 101, the first support seat is fixed in the shell 1, the first rotating shaft 36 is rotatably arranged on the first support seat, the base 7 is arranged in the shell 1, and the elastic member 6 is fixed between the base 7 and the support plate 2;

[0038] In use, the shell 1 can be buried underground, so that the top surface of the shell 1 is flush with the ground, and the tires are located on the support plate 2 by driving the automobile, and two support plates 2 are arranged through the two through holes 101, so that the two front wheels or the two rear wheels of the automobile can be detected at the same time. After detecting the two front wheels, the automobile is driven to make the two rear wheels located on the support plate 2 for detection, so as to avoid the trouble of occupying a large volume of equipment caused by using four support plates 2, and reduce the trouble of adjusting the position of the automobile relative to the single support plate 2.

[0039] As shown in Figure 4 and Figure 5 , the support plate 2 is provided with a side plate 21 on both sides, and the two side plates 21 are rotatably connected to the first rotating rod 4 on the opposite side, and the first rotating rod 4 is fixedly connected to the first support frame 37.

[0040] Through such arrangement, when the first support frame 37 swings in an arc shape around the first rotating shaft 36, the support plate 2 can move vertically under the pressure of the automobile, and can also be slightly offset to the left and right (in the perspective of Figure 4 , so as to effectively prevent the automobile tires from being separated from the support plate 2 when the automobile is in an inclined state.

[0041] As shown in Figure 4 and Figure 5 , the stable limiting assembly 5 includes a second rotating shaft 52, a second rotating rod 51 and a second support frame 53, the second support frame 53 is parallel to the first support frame 37, the second support seat is fixed in the shell 1, the second rotating shaft 52 is rotatably arranged on the second support seat, the second support frame 53 is fixedly installed on the second rotating shaft 52, the two side plates 21 are rotatably connected to the second rotating rod 51 on the opposite side, the second rotating rod 51 is fixedly connected to the second support frame 53, and the line connecting the centers of the second rotating rod 51 and the first rotating rod 4 is perpendicular to the horizontal plane.

[0042] To further ensure that the first support frame 37 swings around the first rotating shaft 36, the support plate 2 can vertically move under the pressure of the automobile, the stable limiting component 5 is arranged, when the power component drives the first support frame 37 to swing around the first rotating shaft 36, the support plate 2 drives the side plate 21 to move, the side plate 21 drives the second support frame 53 to swing around the second rotating shaft 52, the second support frame 53 and the first support frame 37 synchronously move, under the limiting effect of the first rotating shaft 4 and the second rotating shaft 51, the support plate 2 can more stably vertically move, and simultaneously a small amount of deviation is generated.

[0043] As shown in Figure 2 and Figure 3 The second connecting plate 35 is triangular, has a pointed end and a flat end, the flat end is fixed with the sleeve rod 38, and the pointed end is fixed with the hinge seat 34.

[0044] If both ends of the second connecting plate 35 are flat, the horizontal distance from the motor 31 to the support plate 2 is increased, thereby increasing the volume of the entire device, if both ends of the second connecting plate 35 are pointed, the strength of the second connecting plate 35 is insufficient, and when the power component drives the second connecting plate 35 to swing, the second connecting plate 35 may be broken due to insufficient strength, by arranging the second connecting plate 35 in a triangular shape, the strength of the second connecting plate 35 is ensured, and the volume of the entire device is relatively small and the structure is more compact.

[0045] As shown in Figure 4 The first support frame 37 is fixedly installed with the counterweight 8 at an end away from the first rotating shaft 36, and the elastic member 6 is pre-pressed.

[0046] As shown in Figure 1 The top surface of the support plate 2 is provided with at least two blocking rods 9, by arranging the blocking rods 9, the automobile tire can be limited, so that the support plate 2 is in a relatively stable state when vibrating.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
