[0002] To ensure automotive products achieve the required service life and reliability, test fixtures are crucial equipment for guaranteeing testing accuracy and efficiency. Currently, commonly used test fixtures are typically welded integral fixtures. While these fixtures have a simple structure, they are cumbersome to operate, have a fixed center point, and are prone to damage due to center of gravity misalignment; their testing accuracy is also inaccurate. The next step involves first conducting structural analysis, fatigue life prediction, and design improvements on the product. Finally, testing is performed to verify the accuracy of the fatigue life prediction and ensure the product achieves the required service life and reliability. This type of testing is called durability testing.

[0003] Currently, according to feedback from the vehicle testing ground, there is a cracking problem at the weak point of the elbow of the Electronic Park Brake (EPB) bracket in the actual vehicle. In order to reproduce and solve the problem in the actual vehicle, vibration testing is very necessary. In the past, the related fixtures matched with the electromagnetic vibration test bench were heavy, the assembly of the sample was time-consuming, and only one EPB bracket could be tested at a time. This significantly reduced work efficiency and increased testing costs when testing batches or multiple models.

[0004] No effective solution has yet been proposed to address the aforementioned technical issues. Utility Model Content

[0033] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0034] Combination Figures 1 to 3 As shown, according to a specific embodiment of the present invention, a vibration test fixture for an electronic parking module is provided.

[0035] Specifically, such as Figure 1 As shown, the vibration test fixture for the electronic parking module includes: a base plate 10, which is used to be mounted on the electromagnetic vibration test bench 300; and a support assembly 20, which is located on the base plate 10 and has multiple test positions for connecting the electronic parking module 100.

[0036] In this embodiment, by setting the base plate 10 and the support component 20, the stability and rigidity of the fixture are ensured. By setting multiple test positions on the support component, multiple electronic parking modules 100 can be subjected to vibration tests at the same time, which not only improves the testing efficiency but also enhances the versatility of the fixture, making it suitable for electronic parking modules 100 of different sizes and shapes.

[0037] Meanwhile, both the base plate 10 and the support assembly 20 are made of aluminum, which has the advantages of being lightweight, high-strength, and corrosion-resistant. This ensures the overall quality of the clamp and the rigidity of the connection, greatly improving installation efficiency and reducing the burden on vibrating equipment.

[0038] Furthermore, there are at least two test positions, with one test position at each end of the support component 20. This arrangement allows the electronic parking module 100 to be tested simultaneously at both ends, significantly accelerating the testing process, improving testing efficiency, and enabling the testing of more samples to be completed in the same amount of time.

[0039] In one embodiment, the base plate 10 has a length of 600mm, a width of 600mm, and a thickness of 20mm. However, the specific values ​​of the length, width, and thickness of the base plate 10 are not limited to these and may be used in other embodiments.

[0040] Furthermore, the support assembly 20 includes: a first support member 21, which is located on the base plate 10; and a second support member 22, which is located on one side of the first support member 21 and extends along the length direction of the first support member 21. The second support member 22 is movably connected to the first support member 21 and is movable relative to the height direction of the first support member 21. A test position is provided on each side of the length direction of the second support member 22.

[0041] Specifically, the movable nature of the second support relative to the first support in the height direction allows the test position to be adjusted according to the different heights of the EPB module under test, enhancing the adaptability and flexibility of the fixture and making it suitable for EPB modules of various sizes.

[0042] Furthermore, the second support member 22 is symmetrically arranged along the center line of the height direction of the first support member 21. The symmetrical arrangement of the second support member not only improves the structural stability and testing accuracy of the test fixture, but also simplifies the operation process, improves testing efficiency, and enhances the versatility and adaptability of the fixture.

[0043] Combination Figure 1 , Figure 2As shown, the first support member 21 includes: a first support body 211, which is connected to the base plate 10. The first support body 211 is provided with a plurality of first through holes 212, which extend along the length direction of the first support body 211 and are spaced apart along the height direction of the first support body 211. The first support body 211 is connected to the second support member 22 through the first through holes 212.

[0044] Specifically, the multiple first vias 212 are spaced apart along the height direction, allowing the second support 22 to connect to the first support 21 at different height positions. This means that the test position can be flexibly adjusted in the vertical direction to accommodate EPB modules of different sizes and installation requirements. The arrangement of the first vias 212 enables the installation of the second support 22 to be quick and precise. Operators can quickly select the appropriate first via for connection according to the installation requirements of the sample, improving the efficiency and convenience of sample installation.

[0045] The first through hole 212 is an elongated waist hole with a length of a, where 299.5mm ≤ a ≤ 300.5mm. In one embodiment, the length of the first through hole 212 is 300mm.

[0046] Further, the second support member 22 includes: a second support body 221, which extends along the length direction of the first support body 211. The second support body 221 is provided with a plurality of second through holes 222, which are spaced apart along the length direction of the second support body 221 and spaced apart along the height direction of the second support body 221. The second support body 221 is moved along the height direction of the first support body 211 so that the second through holes 222 of the first layer can selectively correspond to the plurality of first through holes 212. A test position is provided on each side of the length direction of the second support body 221.

[0047] Specifically, the layout of the second via 222 allows the second support 22 to move and be positioned vertically, matching the installation height requirements of different EPB modules and providing excellent sample position adjustment capability. The second support body 221 is connected to the first support body 211 through the via, enhancing the overall structural rigidity of the fixture, ensuring the stability of the sample during testing, as well as the accuracy and stability of the test data.

[0048] Furthermore, the second support body 221 has a plate-like structure, and chamfers are provided at the corners of the second support body 221.

[0049] Furthermore, the second support body 221 has multiple first connection holes 223 on both sides of its length direction. The first connection holes 223 on both sides are symmetrically arranged along the center line of the height direction of the second support body 221. The second support body 221 is connected to the connecting frame 200 through the first connection holes 223. The connecting frame 200 is connected to the electronic parking module 100.

[0050] Specifically, the symmetrical design of the first connecting hole 223 helps maintain the balance of the entire test system's center of gravity, reducing the impact of center of gravity shift on test accuracy and equipment stability under high-frequency vibration environments. The cooperation between the first connecting hole 223 and the connecting bracket 200 allows the electronic parking module 100 to be quickly and accurately installed at the test position, simplifying the installation process and improving work efficiency.

[0051] Furthermore, the first support body 211 is provided with a clearance passage 213, which is used for the hoisting mechanism to pass through.

[0052] Specifically, the clearance passage 213 ensures that the hoisting mechanism can pass through directly without obstruction, making the hoisting and unloading process of the sample smoother and avoiding the risk of collision with the clamp during the hoisting process.

[0053] Furthermore, the support assembly 20 also includes: a reinforcing member 23, of which there are at least two reinforcing members 23, which are located on the base plate 10, with one end of the reinforcing member 23 connected to the base plate 10 and the other end of the reinforcing member 23 connected to the first support body 211.

[0054] Specifically, by setting at least two reinforcing members 23 to connect the base plate 10 and the first support body 211, the overall rigidity of the test fixture is significantly enhanced, structural deformation during vibration testing is reduced, and the accuracy of the test is improved.

[0055] Furthermore, the first support body 211 is provided with a plurality of third through holes 214, which are symmetrically arranged along the center line of the length direction of the first support body 211. The plurality of third through holes 214 located on one side of the center line of the length direction of the first support body 211 are spaced apart along the height direction of the first support body 211. The bottom plate 10 is provided with a plurality of fourth through holes 11. One end of each reinforcing member 23 is connected to the first support body 211 through the third through hole 214, and the other end of each reinforcing member 23 is connected to the bottom plate 10 through the fourth through hole 11.

[0056] Specifically, the symmetrical design of the third through hole 214 and the fourth through hole 11 ensures that the reinforcing member 23 is evenly distributed between the first support body 211 and the base plate 10, thereby forming a stable triangular support in the structure, improving the force transmission efficiency and the overall rigidity of the structure.

[0057] Furthermore, the first support body 211 is provided with a plurality of second connection holes 215, and the first support body 211 is connected to the base plate 10 through the plurality of connection holes 215.

[0058] Combination Figure 3 As shown, the bottom of the first support body 211 is provided with a plurality of second connection holes 215 for connecting with the base plate 10, and the top and side walls of the first support body 211 are also provided with a plurality of second connection holes 215 for connecting other equipment.

[0059] Furthermore, the electronic parking module vibration test fixture of this application is made entirely of aluminum. Aluminum has advantages such as light weight, high strength, and good corrosion resistance, which ensures the overall quality of the fixture and the rigidity of the connection, greatly improving installation efficiency and reducing the burden on the vibration equipment.
