To facilitate driver operation, prevent traffic accidents, and ensure personal safety, all countries mandate the installation of rearview mirrors in automobiles. With continuous advancements in automotive technology, features such as electrically adjustable rearview mirrors, electrically defrosting and heated mirrors, and automatic folding / unfolding mirrors when opening and closing doors have gradually become standard features in rearview mirror development, catering to driver comfort and safety needs.

[0003] Furthermore, the testing benches for rearview mirror folding durability testing on the market have limited functionality and poor adaptability, and cannot simultaneously test the left and right rearview mirrors at the same time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-functional testing instrument for rearview mirror testing that has strong adaptability and high testing efficiency.

[0005] This utility model discloses a multifunctional testing instrument for rearview mirror testing, comprising:

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Reference Figures 1-5 This embodiment provides a multi-functional testing instrument for rearview mirror testing, comprising:

[0037] Mounting base 1 is the basic component of the entire detector and is set up independently and fixedly.

[0038] Two mounting shafts 2 are rotatably mounted in the two shaft holes of the mounting base 1, and a support 3 is fixedly mounted on the mounting shaft 2. The support 3 is provided with two clamping mechanisms 4 for firmly clamping the folding end of the rearview mirror to be tested. The rearview mirror can rotate around the mounting shaft 2 to simulate the folding action in actual use.

[0039] Two transmission gears 5 are coaxially fixedly mounted on two mounting shafts 2, and the two transmission gears 5 are meshed. When one mounting shaft 2 is driven, the other mounting shaft 2 will also move synchronously, thereby realizing the simultaneous folding and unfolding of the two rearview mirrors.

[0040] Two detection units 6 are respectively installed on the mounting base 1, and the two detection units 6 are respectively installed with two support members 3 to detect the number of times the rearview mirror is folded;

[0041] Two mounting mechanisms 7 are respectively mounted on two mounting bases 1. The mounting mechanisms 7 are used to fix and clamp the rearview mirror.

[0042] The drive mechanism 8 is installed in the inner cavity of the mounting base 1. The drive mechanism 8 is connected to two mounting shafts 2. The drive mechanism 8 is used to provide folding power to the rearview mirrors held by the two clamping mechanisms 4.

[0043] In this embodiment, the rearview mirror to be tested is first fixed by the mounting mechanism 7. Then, the folding end of the rearview mirror is clamped by two clamping mechanisms 4. The drive mechanism 8 is started, and the drive mechanism 8 drives the mounting shaft 2 to rotate, thereby causing the clamping mechanism 4 on the support 3 to drive the rearview mirror to fold or unfold. The transmission gear 5 ensures that the rearview mirrors on both sides can move synchronously. The detection unit 6 monitors the rearview mirror in real time the number of folds.

[0044] The mounting base 1 serves as a fundamental component, providing stable support for the overall structure and ensuring the stability of each component's position during testing. Two mounting shafts 2, in conjunction with the support member 3 and clamping mechanism 4, firmly clamp the folding end of the rearview mirror. The rotation of the mounting shafts 2 simulates the folding action in actual use, enabling a realistic test of the rearview mirror's mechanical performance. The meshing design of the two transmission gears 5 allows the mounting shafts 2 on both sides to move synchronously, ensuring synchronized testing of the left and right rearview mirrors and improving the reliability of the test results. The detection unit 6, in conjunction with the support member 3, can accurately record the number of folds of the rearview mirror in real time, providing data support for evaluating the rearview mirror's service life. The mounting mechanism 7 securely clamps the rearview mirror under test, ensuring the accuracy of the rearview mirror's position during testing and reducing test deviations caused by installation errors. The drive mechanism 8, installed inside the mounting base 1, works with the mounting shafts 2 to provide stable folding power, achieving automated driving of the testing process, reducing manual operation intensity, and improving testing efficiency.

[0045] As a preferred embodiment of the above technical solution, such as Figures 1 to 5 As shown, the clamping mechanism 4 includes:

[0046] The movable part 41 is slidably installed in the guide groove of the support part 3, and the axis of the guide groove coincides with the axis of the mounting shaft 2;

[0047] Bolt 42 is installed on movable part 41 through the through groove of support 3. Bolt 42 is used to lock the connection position between movable part 41 and support 3.

[0048] The clamping rod 43 is fixedly installed on the movable part 41, and the clamping rods 43 on the two clamping mechanisms 4 cooperate to clamp the rearview mirror;

[0049] When the two clamping mechanisms 4 drive the rearview mirror to fold, the folding axis of the rearview mirror coincides with the rotation axis of the mounting shaft 2;

[0050] The clamping rod 43 is rotatably mounted on the protective sleeve 44;

[0051] In this embodiment, the movable part 41 slides along the guide groove of the support 3, and the clamping distance can be adjusted according to the size of the folding end of the rearview mirror. The position is locked by the bolt 42 to ensure compatibility with various models of rearview mirrors and improve the versatility of the tester. The clamping rods 43 of the two clamping mechanisms 4 cooperate to clamp the rearview mirror. The folding axis of the rearview mirror coincides with the rotation axis of the mounting shaft 2. The clamping rods 43 provide stability for the rearview mirror and reduce the relative displacement caused by rotation. The protective sleeve 44 rotatably installed on the clamping rods 43 is made of elastic material, which can reduce the hard wear on the surface of the rearview mirror during clamping. At the same time, it adapts to the angle change when the rearview mirror is folded through rotation characteristics, avoiding component damage caused by rigid contact and ensuring that the appearance and structure of the rearview mirror are not damaged during the test.

[0052] Specifically, such as Figures 1 to 4As shown, the drive mechanism 8 includes:

[0053] A drive motor 81 is installed in the inner cavity of the mounting base 1, and a sector gear 82 is installed at the output end of the drive motor 81.

[0054] Two connecting gears 83 are coaxially fixedly mounted on two mounting shafts 2, and the sector gear 82 meshes with the two connecting gears 83.

[0055] The mounting base 1 is provided with two positioning shafts 84, and the two support members 3 are respectively installed in cooperation with the two positioning shafts 84. The positioning shafts 84 are used to limit the position of the support members 3 after the sector gear 82 is disengaged from the connecting gear 83.

[0056] In this embodiment, the drive motor 81 is installed inside the mounting base 1. Its output sector gear 82 meshes with two connecting gears 83. This meshing of the sector gear 82 with the two connecting gears 83 generates opposing rotational forces on the support shaft 2. The stability of the gear transmission ensures the uniformity and synchronization of the rearview mirror folding / unfolding action. The positioning shaft 84 cooperates with the support member 3. After the sector gear 82 disengages from the connecting gears 83 (e.g., at the end of the test or during a stop), it limits the position of the support member 3, preventing the mounting shaft 2 from rotating freely due to inertia or external force. This ensures the rearview mirror remains in the designated test position, improving the safety and positioning accuracy of the test process. This design, through the high efficiency of gear transmission and the limiting function of the positioning shaft 84, not only achieves automated control of the test process and reduces manual intervention costs, but also ensures the stability and reliability of the rearview mirror folding test through precise power transmission and position locking. It is suitable for long-term, high-frequency automated testing scenarios.

[0057] Specifically, such as Figures 1 to 2 As shown, the mounting mechanism 7 includes:

[0058] The fixing seat 71 is installed on the mounting base 1, and at least two positioning posts 72 are provided on the fixing seat 71;

[0059] Assembly 73 is mounted on mounting base 71 via positioning post 72. Assembly 73 is used for the fixed installation of rearview mirror.

[0060] The locking element 74 is installed with an external thread on the top of the positioning post 72. The locking element 74 is used to lock the connection between the assembly 73 and the fixed base 71.

[0061] In this embodiment, the mounting base 71 is installed on the mounting base 1, and the positioning post 72 on it provides a precise positioning reference for the assembly 73, ensuring the consistency of the rearview mirror installation position and reducing test errors caused by manual alignment deviation. The assembly 73 is fitted onto the mounting base 71 through the positioning post 72. Different specifications of the assembly 73 can be replaced according to the rearview mirror model, improving the adaptability of the tester to diverse products. The locking member 74 is engaged with the external thread at the top of the positioning post 72, and the assembly 73 is firmly locked to the mounting base 71 by tightening, forming a rigid connection. This prevents the rearview mirror from shifting due to vibration or force during the test. At the same time, the threaded connection facilitates quick disassembly and assembly, improving test efficiency.

[0062] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, the bottom of the mounting base 1 is provided with an adjusting foot assembly 9;

[0063] In this embodiment, the adjustable foot assembly 9 can adjust the height of each support foot by means of screw rotation or other methods according to the flatness requirements of the test platform, so as to ensure that the mounting base 1 remains in a horizontal state and avoid uneven force during the rearview mirror test due to the tilt of the platform, which would affect the accuracy of the test results.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
