The performance of the active suspension directly affects the vibration reduction effect and is related to the riding comfort of the passengers in the vehicle. However, the existing active suspension performance testing equipment is not accurate enough when used. Summary of the Invention

[0006] Preferably, the top of the active suspension mount is connected to the interior of the fixed housing via a first guiding telescopic component, so as to guide the lifting and lowering of the active suspension mount.

[0007] Preferably, the bottom of the knocking component is connected to the movable seat through a second guiding telescopic component, which is used to guide the lifting and lowering movement of the knocking component.

[0008] Preferably, the pulling mechanism includes an adjustable telescopic component installed on the inner walls on both sides of the cavity; a movable mounting seat with a U-shaped structure is installed at one end of the piston rod of the adjustable telescopic component; a toggle roller is movably installed inside the movable mounting seat; the two toggle rollers are respectively located on both sides of the pulling rope; and a third driving component is also included for driving the toggle roller to rotate.

[0009] Preferably, a second protrusion is provided on the side of the pulling rope; and a first protrusion is provided on the circumference of the activating roller, for increasing the friction between the activating roller and the pulling rope.

[0010] Preferably, an amplitude drawing mechanism is further included for drawing the amplitude of the test component during the test process.

[0013] When in use, the pulling rope is moved toward the inside of the cavity by the pulling mechanism, and the knocking component is pulled downward by the pulling rope, so that the knocking component moves toward the movable seat and compresses the push spring. When the pulling mechanism releases the pulling of the pulling rope, the knocking component knocks the acting component under the elastic action of the push spring, and the vibration isolation effect of the active suspension is judged by the vibration of the test component. When the acting component is subjected to the force of the knocking component and moves in the vertical direction, the guide rail guides the movement of the acting component, and the force of the knocking component knocking on the side of the acting component can be changed by pulling the knocking component downward, that is, by changing the compression of the push spring.

[0021] When in use, the pulling rope 22 is moved toward the inside of the cavity 4 by the pulling mechanism 23, and the knocking component 17 is pulled downward by the pulling rope 22, so that the knocking component 17 moves toward the movable seat 2 and compresses the push spring 19. When the pulling mechanism 23 releases the pulling rope 22, the knocking component 17 knocks on the action component 5 under the elastic action of the push spring 19, and the vibration isolation effect of the active suspension 7 is judged by the vibration of the test component 10. When the action component 5 is subjected to the force of the knocking component 17 and moves in the vertical direction, the guide rail 15 is pressed against the action component 5. The movement of the component 5 is guided, and the force exerted by the knocking component 17 on the side of the action component 5 can be changed by pulling the knocking component 17 downward, that is, by changing the compression of the push spring 19. It is easy to use and easy to adjust, and the movable seat 2 can be driven by the first driving component 3 to move horizontally on the base 1 to change the position where the knocking component 17 knocks the action component 5; the action component 5 can also be knocked by the knocking component 17 during the process of the first driving component 3 driving the movable seat 2 to move horizontally, thereby simulating the state of the vehicle driving, and the test is more comprehensive and accurate.

[0022] As a preferred embodiment of the present invention, the top of the active suspension mount 8 is connected to the interior of the fixed housing 13 via a first guiding telescopic component 12 for guiding the lifting and lowering of the active suspension mount 8 .

[0023] As a preferred embodiment of the present invention, the bottom of the knocking component 17 is connected to the movable seat 2 through a second guiding telescopic component 20, which is used to guide the lifting and lowering movement of the knocking component 17 to ensure that the force exerted by the knocking component 17 on the action component 5 is only in the vertical direction.

[0024] As a preferred embodiment of the present invention, the pulling mechanism 23 includes an adjustable telescopic component 234 installed on the inner walls on both sides of the cavity 4; a movable mounting seat 233 with a U-shaped structure is installed at one end of the piston rod of the adjustable telescopic component 234; a toggle roller 231 is movably installed inside the movable mounting seat 233; the two toggle rollers 231 are respectively located on both sides of the pulling rope 22; and it also includes a third driving component for driving the toggle roller 231 to rotate, and the movable mounting seat 233 can be pushed to move horizontally by adjusting the telescopic component 234, so that the two toggle rollers 231 clamp the two sides of the pulling rope 22, and the toggle roller 231 is driven to rotate by the third driving component, and the toggle roller 231 to toggle the pulling rope 22 to the inside of the cavity 4, thereby pulling the knocking component 17 toward the movable seat 2.

[0025] As a preferred embodiment of the present invention, a second protrusion 21 is provided on the side of the pulling rope 22; a first protrusion 232 is provided on the circumference of the moving roller 231, which is used to increase the friction between the moving roller 231 and the pulling rope 22 to ensure that the moving roller 231 can effectively move the pulling rope 22.

During the test, the drawing component 91 rises and falls with the rise and fall of the test component 10, and at the same time, the amplitude drawing board 92 is driven to move horizontally at a uniform speed by the second driving component 93, so that the drawing component 91 leaves wavy lines on the amplitude drawing board 92.
