DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 The automobile suspension test bench comprises a first test platform 1 and a second test platform 2. A slope is arranged on the side of the second test platform 2 away from the first test platform 1. The first test platform 1 is slidably connected with the second test platform 2 through a translation mechanism 3. The translation mechanism 3 is used to drive the first test platform 1 to move horizontally. The first test platform 1 and the second test platform 2 are both provided with symmetrically distributed support blocks 5. The tops of the support blocks 5 are both provided with trapezoidal grooves. The bottoms of the support blocks 5 extend into the first test platform 1 and the second test platform 2 respectively and are fixed with support columns 6. The support columns 6 are connected with a vibration mechanism 4. The vibration mechanism 4 is used to drive the support blocks 5 to vibrate back and forth.

[0027] In this embodiment, when testing the automobile suspension, the staff drives the automobile to the surface of the first testing platform 1 and the second testing platform 2 through the slope on the second testing platform 2, and the two front wheels of the automobile are supported by two support blocks 5 symmetrically distributed inside the first testing platform 1, and the two rear wheels of the automobile are supported by two support blocks 5 symmetrically distributed inside the second testing platform 2, and trapezoidal grooves are provided inside the support blocks 5. The tires of the automobile are limited by the trapezoidal grooves, which can effectively improve the stability of the automobile suspension during the testing process. After the support blocks 5 support the tires of the automobile, the support blocks 5 can be driven to vibrate back and forth by the vibration mechanism 4, so as to test the performance of the automobile suspension, wherein the first testing platform 1 is connected to the second testing platform 2 by the translation mechanism 3. Before testing the automobile suspension, the first testing platform 1 can be driven to move horizontally by the translation mechanism 3, thereby adjusting the distance between the support blocks 5 on the two testing platforms, so that the testing platform can be suitable for automobiles with different wheelbases, effectively improving the scope of application of the testing platform.

[0028] See also Figure 1 The translation mechanism 3 includes a mounting plate 32 fixed on the side wall of the second detection platform 2 and a fixing plate 34 fixed on the side wall of the first detection platform 1, a first motor 31 is mounted on the mounting plate 32, a threaded rod 33 is mounted on the output end of the first motor 31, and the threaded rod 33 passes through the fixing plate 34 and is threadedly connected to the fixing plate 34;

[0029] When it is necessary to adjust the distance between the support blocks 5 on the two detection platforms, start the first motor 31, which drives the threaded rod 33 to rotate, and drives the first detection platform 1 to move horizontally through the threaded connection between the threaded rod 33 and the fixed plate 34, thereby adjusting the distance between the support blocks 5 on the two detection platforms, so that the detection platform can be suitable for cars with different wheelbases, effectively improving the application range of the detection platform.

[0030] See also Figure 1A slider 36 is fixed at the bottom of the first detection platform 1, and a slideway 35 adapted to the slider 36 is provided on the surface of the second detection platform 2. The slider 36 is located inside the slideway 35 and is slidably connected to the slideway 35;

[0031] The slideway 35 can limit the first detection platform 1 through the slider 36, thereby effectively improving the stability of the first detection platform 1 during horizontal movement.

[0032] See also Figure 1 A support plate 37 is fixed on one side of the first detection platform 1 close to the second detection platform 2, and the top of the support plate 37 is flush with the tops of the first detection platform 1 and the second detection platform 2. A support groove 38 adapted to the support plate 37 is provided on the top of the second detection platform 2, and the support plate 37 is located inside the support groove 38 and is slidably connected to the support groove 38;

[0033] When the first inspection platform 1 moves, it also drives the support plate 37 to slide inside the support groove 38. The support plate 37 supports the car so that the two front wheels of the car can move smoothly to the surface of the first inspection platform 1, avoiding the phenomenon that the car tires are stuck between the first inspection platform 1 and the second inspection platform 2.

[0034] See also Figure 2 and Figure 3 The vibration mechanism 4 includes an extrusion plate 43 fixedly connected to the bottom of the support column 6, and the first detection platform 1 is internally fixed with symmetrically distributed limiting columns 42, and the limiting columns 42 all penetrate the extrusion plate 43 and are slidably connected to the extrusion plate 43. The first detection platform 1 is internally provided with an extrusion component, and the extrusion component is used to extrude the extrusion plate 43;

[0035] When testing the automobile suspension, the extrusion plate 43 inside the first testing platform 1 is squeezed by the extrusion assembly, and the extrusion plate 43 drives the support block 5 to move upward through the support column 6, and the support block 5 drives the front wheel of the automobile to move upward. When the extrusion assembly no longer squeezes the extrusion plate 43, the support block 5 gradually moves downward under the action of the gravity of the automobile. At this time, the staff can feel the vibration inside the automobile, thereby achieving the purpose of automobile suspension testing. The limit column 42 has a limiting effect on the extrusion plate 43, which effectively improves the stability of the extrusion plate 43 when moving. In addition, the extrusion plate 43 inside the second testing platform 2 can be tested by the extrusion assembly inside the second testing platform 2, thereby testing the suspension on the rear side of the automobile.

[0036] See also Figure 1 and Figure 3The extrusion assembly includes a second motor 41 fixed on the outer wall of the first detection platform 1, a rotating rod 44 is fixed to the output end of the second motor 41, and the rotating rod 44 extends into the first detection platform 1, wherein a push block 45 for extruding the extrusion plate 43 is fixed to the outside of the rotating rod 44;

[0037] When testing the automobile suspension, the second motor 41 is started, and the second motor 41 drives the push block 45 to rotate through the rotating rod 44. When the push block 45 rotates to a certain extent, the push block 45 squeezes the extrusion plate 43, so that the extrusion plate 43 drives the support block 5 to move upward through the support column 6, and then drives the automobile tire to move upward. When the degree of squeezing of the extrusion plate 43 by the push block 45 decreases, the support block 5 gradually moves downward under the action of the gravity of the automobile, and this cycle is repeated, so that the automobile tire can continuously vibrate up and down, thereby achieving the purpose of suspension testing.

[0038] In one embodiment, see Figure 4 and Figure 5 The fixing columns 416 are provided with grooves inside, and the grooves are slidably connected with trapezoidal blocks 412 inside. The trapezoidal blocks 412 are connected to the inner wall of the grooves through the first elastic components 411, wherein the trapezoidal blocks 412 are connected with traction components, and the traction components are used to pull the trapezoidal blocks 412 into the grooves. The extrusion plates 43 are provided with limiting grooves 413 adapted to the trapezoidal blocks 412.

[0039] When the pushing block 45 squeezes the squeezing plate 43, the squeezing plate 43 can only move downward slowly when the squeezing degree of the squeezing plate 43 by the pushing block 45 decreases, thereby driving the automobile tire to move downward slowly. In the present embodiment, when the pushing block 45 squeezes the squeezing plate 43 to the highest point, the trapezoidal block 412 is aligned with the limiting groove 413, and the trapezoidal block 412 automatically enters the limiting groove 413 under the action of the first elastic component 411. The trapezoidal block 412 supports the squeezing plate 43 through the limiting groove 413, thereby limiting the downward movement of the squeezing plate 43. As the pushing block 45 continues to rotate, the automobile tire will not move downward. When the pushing block 45 rotates to the lowest point, the pushing block 45 pulls the The trapezoidal block 412 is pulled into the inside of the trough body, and the trapezoidal block 412 no longer supports the extrusion plate 43 through the limit groove 413. The car tire moves downward rapidly under the action of gravity, thereby simulating the influence of another vibration on the car suspension, such as a car driving directly down from the steps, which effectively improves the detection range of the test platform for the car suspension, wherein the first elastic component 411 can be a spring. In addition, in order to avoid the phenomenon that the extrusion plate 43 falls rapidly and directly hits the side wall of the push block 45, a baffle 414 for supporting the extrusion plate 43 is fixed on the inner wall of the test platform, and the extrusion plate 43 is supported by the baffle 414. When the extrusion plate 43 hits the baffle 414, the top of the support block 5 is just flush with the top of the test platform.

[0040] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 The traction component includes a slide groove arranged on the side wall of the limiting column 42, a push plate 46 is arranged below the push block 45, and a symmetrically distributed guide column 47 is fixed to the bottom of the push plate 46, and a symmetrically distributed guide groove is arranged at the bottom of the first detection platform 1, and the guide column 47 is inserted into the guide groove and connected to the guide groove through the second elastic component 48, and a symmetrically distributed moving block 410 is fixed on the side wall of the push plate 46, and the moving block 410 is located inside the slide groove and is slidably connected to the slide groove, and the moving block 410 is fixedly connected to the first traction rope 49, and the other end of the first traction rope 49 extends to the inside of the groove body and is fixedly connected to the trapezoidal block 412;

[0041] When the push block 45 rotates to a certain extent, the push block 45 squeezes the push plate 46, and the push block 45 drives the moving block 410 to move downward inside the slide groove. The moving block 410 pulls the trapezoidal block 412 through the first traction rope 49, thereby pulling the trapezoidal block 412 into the groove body, and the trapezoidal block 412 no longer supports the squeezing plate 43, so that the automobile tire can move downward quickly. When the push block 45 no longer squeezes the push plate 46, the push plate 46 automatically resets under the action of the second elastic component 48, so that the trapezoidal block 412 can automatically reset. The second elastic component 48 can be a spring, and the guide groove plays a limiting role on the push plate 46 through the guide column 47, which effectively improves the stability of the push plate 46 when moving.

[0042] See also Figure 6 A second traction rope 415 is fixed to the bottom of the push plate 46, and the second traction rope 415 passes through the first detection platform 1. A fixing column 416 is fixed to one end of the second traction rope 415 passing through the first detection platform 1, and a fixing groove 417 adapted to the fixing column 416 is provided on the outer wall of the first detection platform 1;

[0043] When the automobile tire needs to move slowly downward, the fixing column 416 is inserted into the fixing groove 417. During the insertion process, the fixing column 416 pulls the push plate 46 through the second traction rope 415. The push plate 46 pulls the trapezoidal block 412 through the moving block 410 and the first traction rope 49, so that the trapezoidal block 412 is always located inside the groove body. The trapezoidal block 412 cannot support the extrusion plate 43, so that the extrusion plate 43 can move slowly downward under the action of the push block 45, thereby simulating another vibration effect on the automobile suspension.

[0044] Working principle: When testing the automobile suspension, the staff drives the automobile to the surface of the first testing platform 1 and the second testing platform 2, and the automobile tires are supported by the support block 5. Then, the second motor 41 drives the rotating rod 44 to rotate, and the rotating rod 44 drives the push block 45 to rotate. When the push block 45 rotates to a certain extent, the push block 45 squeezes the extrusion plate 43, so that the extrusion plate 43 drives the support block 5 to move upward through the support column 6, and then drives the automobile tire to move upward. When the degree of extrusion of the extrusion plate 43 by the push block 45 decreases, the support block 5 slowly moves downward under the action of the gravity of the automobile, and so on and so forth, so that the automobile tire can continuously vibrate up and down, thereby achieving the purpose of suspension testing. In addition, when the push block 45 squeezes the extrusion plate 43 to the highest point, the trapezoidal block 412 is exactly aligned with the limiting groove 413, and the trapezoidal block 412 automatically enters the limiting groove 413. The plate 43 plays a supporting role, thereby limiting the downward movement of the extrusion plate 43. As the push block 45 continues to rotate, the push block 45 squeezes the push plate 46, and the push block 45 drives the moving block 410 to move downward inside the slide slot. The moving block 410 pulls the trapezoidal block 412 through the first traction rope 49, thereby pulling the trapezoidal block 412 into the slot body. The trapezoidal block 412 no longer supports the extrusion plate 43, and the automobile tire moves downward rapidly under the action of gravity, thereby simulating another vibration effect on the automobile suspension, such as the automobile driving directly down from the steps, effectively improving the detection range of the automobile suspension by the test platform, wherein before the automobile suspension is tested, the first detection platform 1 can also be driven to move horizontally through the threaded connection between the threaded rod 33 and the fixed plate 34, thereby adjusting the distance between the support blocks 5 on the two detection platforms, so that the detection platform can be suitable for automobiles with different wheelbases, effectively improving the application range of the detection platform.
