[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A movable clamping mechanism for tilt testing includes a fixed clamp for connecting to one end of a shock absorber, the fixed clamp having an opening on its side, through which the shock absorber can be rotatably connected to the fixed clamp.
[0006] Furthermore, the fixing clip is slidably placed on a connecting bracket, on which a first sliding groove and a second sliding groove are respectively formed, perpendicular to each other, for adjusting and changing the position of the fixing clip.
[0007] Furthermore, the bracket is composed of a base plate and an extension portion vertically disposed on the base plate, and the second groove is located on the extension portion.
[0008] Furthermore, the fixing clamp is slidably mounted on the second sliding groove.
[0009] Furthermore, through holes for rotatable connection of the damper are respectively provided on the upper and lower end faces of the fixing clamp.
[0010] Furthermore, each of the through holes is provided with an elastic component, which is located on the side facing the shock absorber.
[0011] Furthermore, it also includes at least one pair of first grooves formed on the base plate.
[0012] The beneficial effects of this utility model are as follows:
[0013] The movable clamping mechanism for tilt angle testing provided by this utility model uses a first slide groove and a second slide groove to give the tooling two directions of translational freedom adjustment. The opening structure on the fixed clamp is adapted to the working state of the vehicle body end, so that it can be used to fix different types of shock absorbers for testing.

[0018] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. "Longitudinal (X direction)", "lateral (Y direction)" and "vertical (Z direction)" are terms of spatial coordinate system in the automotive field, which are professional terms well known to those skilled in the art. The above description is for the purpose of simplifying the description of this utility model, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features.
[0020] When a component is described in the specification as being "on", "fixed" to, "connected" to, or "joined" to another component, the component may be directly located on, fixed to, connected to, joined to, or in contact with the other component, or there may be an intermediate component present.
[0021] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.
[0022] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.
[0023] Figure 1 and Figure 2 The overall structure of this universal test fixture is shown. The main function of the fixture is to simulate the vehicle body fixed end of the shock absorber, and it can simulate different vehicle mounting angles by changing the position of the fixed end.
[0024] The fixture mainly consists of a support 100 and a fixing clamp 130 mounted on the support 100 for connection to the end of the vibration damper 200. The support 100 includes a base plate 110 connected to the test bench and an extension portion 120 extending vertically from the base plate 110. The base plate 110 has a pair of first sliding grooves 111, allowing it to slide along the X-direction based on the test bench. The fixing clamp 130 is specifically pinned into the second sliding groove 121 using fixing holes 135. The first and second sliding grooves 111 form a 90° angle with each other, allowing the position of the fixing clamp 130 in two degrees of freedom to be changed via the first and second sliding grooves 111 and 121. The fixing clamp 130 has an opening 131 on its side, allowing the vibration damper 200 to extend horizontally from the side and connect to the fixing clamp 130. A first through hole 132 and a second through hole 133 are respectively provided on the upper and lower end faces of the fixing clamp 130. The damper 200 is hinged to the first through hole 132 and the second through hole 133, so that the damper 200 can still rotate at a certain angle within the opening 131 after being fixed to the fixing clamp 130. Furthermore, elastic members 134 are provided on the inner side of the first through hole 132 and the second through hole 133. When the damper 200 is fixed, the end face directly engages with the elastic member 134. In this way, the deformable characteristic of the elastic member 134 allows the damper 200 to swing at a certain Z-axis angle locally after being fixed, which is convenient for sine wave testing.
[0025] In one embodiment, a reinforcing rib 112 is sandwiched between the extension portion 120 and the base plate 110.
[0026] Reference Figure 3 The fixed end 201 of the shock absorber 220 is fixed on the fixed clamp 130, and its other end is the loading end 202 connected to the test bench to simulate the wheel end. The test is carried out by applying force to the loading end 202. Because the structure of the opening 131, the shock absorber 200 has the ability to rotate around the fixed clamp 130 during the test.
