[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0029] Please refer to Figures 1 to 4, A vibration test fixture for a vehicle brake caliper shown in a preferred embodiment of the present application includes a connecting base plate 1, a supporting back plate 2, a dummy wheel structure 3, and a connecting tabletop 4. A plurality of connecting holes 11 are formed in the connecting base plate 1. The supporting back plate 2 is disposed on the connecting base plate 1 and is perpendicularly connected to the connecting base plate 1. A plurality of fixing holes 21 for connecting the caliper specimen are formed in the supporting back plate 2. The dummy wheel structure 3 is disposed on the connecting base plate 1 and is located on one side of the supporting back plate 2, and is used to cooperate with the caliper specimen to simulate vehicle braking. The connecting tabletop 4 is connected to the moving coil of the vibration table and is used for the connecting base plate 1. A plurality of connecting auxiliary holes 41 matching the connecting holes 11 are formed in the connecting tabletop 4.

[0030] Since the vibration excitation provided by the vibration table is usually transmitted to the test piece through the vertical / horizontal connecting tabletop 4, and the connections of the conventional vertical / horizontal connecting tabletop 4 are all standard flat surface connections with standard hole pitches, most non-cubic specimens such as vehicle hydraulic brake calipers cannot be directly mounted on the connecting tabletop 4 for vibration tests. Therefore, according to the solution of the embodiment of the present utility model, by providing the supporting back plate 2 on the connecting base plate 1, fixing the caliper specimen on the fixing holes 21 of the supporting back plate 2, and providing the dummy wheel structure 3 to cooperate with the caliper specimen to simulate vehicle braking, the installation of the caliper specimen is realized through the connection between the connecting base plate 1 and the connecting tabletop 4.

[0031] The following will be described in detail with specific embodiments:

[0032] The connecting tabletop 4 is a horizontal tabletop and is horizontally arranged with the vibration table, or the connecting tabletop 4 is a vertical tabletop and is vertically arranged with the vibration table. Please refer to Figure 4 , In one embodiment, the vibration table is placed horizontally, and the horizontal tabletop is perpendicularly connected to the moving coil of the vibration table. In another embodiment, the vibration table is vertically arranged, and the vertical tabletop is parallel connected to the moving coil of the vibration table. The fixture connects the caliper specimen on the vertical tabletop, and can cooperate with the vibration table to simulate the vibration test in the Z direction.

[0033] Please refer to Figure 1 and Figure 3 , A plurality of connecting holes 11 are arranged in a square array or a circular array, and the corresponding plurality of connecting auxiliary holes 41 are arranged in a square array or a circular array. By matching the design of the connecting holes 11 on the connecting base plate 1 and the connecting auxiliary holes 41 on the connecting tabletop 4, the connecting base plate 1 can simultaneously satisfy the general connection with the horizontal tabletop or the vertical tabletop, and the connecting base plate 1 can be rotated 90 degrees for installation on the horizontal tabletop to solve the problem of only one-dimensional single-axis excitation during horizontal vibration, and meet the vibration tests in the X direction and the Y direction on the horizontal tabletop only.

[0034] Please refer to Figure 1, the fixing holes 21 are close to one end of the supporting back plate 2 away from the connecting bottom plate 1, and several fixing holes 21 are distributed in an arc shape. The dummy wheel structure 3 is a fan-shaped structure, and there is a gap between the dummy wheel structure 3 and the supporting back plate 2. By designing the shapes and positional distributions of the fixing holes 21 and the dummy wheel structure 3, the fixing holes 21 and the dummy wheel structure 3 can be matched with the clamp specimen, so that the installation and fixation of the clamp specimen are more stable, and the positional relationship between the clamp and the wheel hub under different working conditions can be simulated. It should be noted that the clamp specimen and the supporting back plate 2 are connected and fixed by bolts passing through the fixing holes 21.

[0035] Please refer to Figure 2 , a support frame 5 for supporting the dummy wheel structure 3 is arranged on the connecting bottom plate 1. The support frame 5 is located on one side of the supporting back plate 2 and is connected to the supporting back plate 2. The dummy wheel structure 3 is fixed by the support frame 5 to position the position of the dummy wheel framework, ensuring that the clamp specimen can smoothly clamp the dummy wheel structure 3 after being installed on the supporting back plate 2 to simulate the relaxation and tightening states of the clamp specimen.

[0036] Please refer to Figure 2 , several support inclined plates 6 are arranged on the other side of the supporting back plate 2, and the support inclined plates 6 are connected to the connecting bottom plate 1. By setting the support inclined plates 6, the supporting back plate 2 can be further strengthened, so that the installation and fixation of the clamp specimen are more stable.

[0037] Please refer to Figure 3 and Figure 4 , a support platform 7 is arranged at the bottom of the horizontal table for supporting the horizontal table. Setting the support platform 7 can increase the height of the horizontal table, so as to facilitate the connection between the moving coil of the vibration table and the horizontal table, and is more conducive to the conduction of vibration excitation.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0039] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
