Its key technical features include: a frame, a mirror frame fixing bracket, a mirror cover swing bracket, a worktable, a swing cylinder, and an electrical control box. The mirror frame fixing bracket is fixed above the frame, and the mirror cover swing bracket is fixed relative to the mirror frame fixing bracket on the worktable. The actuating end of the swing cylinder acts on the mirror cover swing bracket, driving the mirror cover swing bracket to reciprocate between the closed and open states. The electrical control box is located on the side of the frame and is electrically connected to the swing cylinder. This solution solves the problem of high labor intensity and the inability to conduct sustained product fatigue testing to verify the product's functional requirements in existing technologies.

[0003] In the process of realizing this utility model, the inventors discovered that:

[0004] The problem with the above-mentioned prior art is that the position of the swing cylinder is fixed, and the rotation center point of the mirror cover swing bracket is also fixed. When the rotation center of the sun visor mirror cover cannot coincide with the rotation center of the mirror cover swing bracket, the two are prone to separate during the process of the mirror cover swing bracket driving the sun visor mirror cover to rotate, resulting in the sun visor mirror cover not being able to be rotated completely. Summary of the Invention

[0005] In order to solve the problems existing in the prior art, this utility model proposes a durability test stand for the anti-glare sunshade mirror cover flipping mechanism.

[0006] Therefore, the technical solution of this utility model is as follows: a durability test platform for a mirror cover flipping mechanism of an anti-glare sunshade, comprising a placement platform, a lifting plate movably connected to the front side of the placement platform, a motor fixedly connected to the front side of the lifting plate, the output end of the motor extending through to the rear side of the lifting plate, a rotating arm fixedly connected to the output end of the motor, a telescopic arm movably connected to the right side of the rotating arm, a magnetic sensor fixedly connected to the right side of the top of the telescopic arm, a mounting plate fixedly connected to the front side of the bottom of the placement platform, an adjustment mechanism fixedly connected to the surface of the mounting plate, a sliding groove provided on one side of the top of the placement platform, a clamp slidably connected inside the sliding groove, and the clamp located at the top of the placement platform (this is prior art and can be tightened by threaded connection, and will not be described in detail).

[0007] Preferably, the adjustment mechanism includes a second motor, which is fixedly connected to the bottom of the mounting plate. The output end of the second motor extends through to the top of the mounting plate. A screw is fixedly connected to the output end of the second motor, and a lifting block is threadedly connected to the surface of the screw. The surface of the lifting block is fixedly connected to the surface of the lifting plate.

[0008] Preferably, both sides of the rear side of the mounting plate are fixedly connected with reinforcing ribs, and the top of the reinforcing ribs is fixedly connected to the bottom of the placement platform.

[0009] Preferably, clamping plates are fixedly connected to both sides of the mounting plate, and the surface of the clamping plates is in contact with the surface of the lifting plate.

[0010] Preferably, the surface of the mounting plate is fixedly connected with anti-bending ribs, which are located on the rear side of the screw.

[0011] Preferably, a stabilizing sleeve is fitted onto the top of the screw surface, and the top of the stabilizing sleeve is fixedly connected to the bottom of the placement platform.

[0012] Beneficial effects: Compared with the prior art, this utility model, by adding a rotating arm and other structures to the motor and combining it with a movable telescopic arm, can accurately simulate the actual flipping action of the anti-glare sun visor cover, and can complete the durability test without manual intervention; by adding a magnetic sensor and other structures to the telescopic arm, the flipping position, positioning status and number of flips of the cover can be monitored in real time, and abnormalities such as jamming or misalignment of the cover during the test can be detected in a timely manner, which facilitates quick location of product problems.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings, but this embodiment should not be construed as a limitation of this utility model.

[0019] This utility model is as follows Figures 1 to 3 As shown:

[0020] A durability test bench for a mirror cover flipping mechanism of an anti-glare sunshade includes a placement platform 1. A lifting plate 2 is movably connected to the front side of the placement platform 1. A motor 3 is fixedly connected to the front side of the lifting plate 2. The output end of the motor 3 extends through to the rear side of the lifting plate 2. A rotating arm 4 is fixedly connected to the output end of the motor 3. A telescopic arm 5 is movably connected to the right side of the rotating arm 4. A magnetic sensor 6 is fixedly connected to the right side of the top of the telescopic arm 5. A mounting plate 7 is fixedly connected to the front side of the bottom of the placement platform 1. An adjustment mechanism is fixedly connected to the surface of the mounting plate 7. A sliding groove 13 is provided on one side of the top of the placement platform 1. A clamp 14 is slidably connected inside the sliding groove 13 and is located on the top of the placement platform 1.

[0021] In this embodiment, the adjustment mechanism includes a second motor 81, which is fixedly connected to the bottom of the mounting plate 7. The output end of the second motor 81 extends through to the top of the mounting plate 7. A screw 82 is fixedly connected to the output end of the second motor 81. A lifting block 83 is threadedly connected to the surface of the screw 82. The surface of the lifting block 83 is fixedly connected to the surface of the lifting plate 2.

[0022] In this technical solution, by setting up motor 2 81, the electric adjustment method is not only more convenient to operate than manual adjustment, but also ensures the lifting accuracy of the lifting plate 2, thereby accurately adjusting the height position of motor 1 3, rotating arm 4 and telescopic arm 5, so that they maintain the best test fit with the sunshade mirror cover at different installation heights.

[0023] In this embodiment, both sides of the rear side of the mounting plate 7 are fixedly connected with reinforcing ribs 9, and the top of the reinforcing ribs 9 is fixedly connected to the bottom of the placement platform 1.

[0024] In this technical solution, the setting of reinforcing ribs 9 prevents the test component from shifting due to deformation of the mounting plate 7, avoids interference with the test process due to equipment failure, reduces equipment maintenance costs, and also provides protection for operational safety during the test process.

[0025] In this embodiment, clamping plates 10 are fixedly connected to both sides of the mounting plate 7, and the surface of the clamping plate 10 is in contact with the surface of the lifting plate 2.

[0026] In this technical solution, the clamping plate 10 ensures that the lifting plate 2 always maintains vertical and stable movement, thereby ensuring the positional stability of the motor 3, rotating arm 4 and telescopic arm 5, so that the mirror cover flipping action is always precise and controllable. The contact between the clamping plate 10 and the lifting plate 2 can also play a certain buffering role, reducing the impact during the lifting process, protecting the equipment components, and extending their service life.

[0027] In this embodiment, the surface of the mounting plate 7 is fixedly connected with an anti-bending rib 11, which is located on the rear side of the screw 82.

[0028] In this technical solution, by setting the anti-bending rib 11, the screw 82 is prevented from tilting or jamming due to the deformation of the mounting plate 7, ensuring the smooth transmission of the screw 82 and thus ensuring the normal realization of the lifting and adjusting function. The anti-bending rib 11 can achieve the effect of enhancing strength without significantly increasing the thickness of the mounting plate 7, taking into account both structural stability and economy.

[0029] In this embodiment, a stabilizing sleeve 12 is fitted on the top of the surface of the screw 82, and the top of the stabilizing sleeve 12 is fixedly connected to the bottom of the placement platform 1.

[0030] In this technical solution, by setting the stabilizing sleeve 12, the service life of the screw 82 and the lifting block 83 can be extended, the equipment maintenance frequency can be reduced, and the stable rotation of the screw 82 can also ensure that the lifting block 83 has a uniform lifting speed and accurate position, further ensuring the positional accuracy of the lifting plate 2 and the test components, and providing strong support for the accuracy of the test action.

[0031] The working principle of this utility model:

[0032] In use, first place the anti-glare sunshade M on the top of the placement platform 1. The clamp 14 inside the slide 13 can be adjusted in real time. The clamp 14 can fix the sunshade on the top of the placement platform 1. The user adjusts the center height of the rotating arm 4 according to the thickness of the anti-glare sunshade. Start the motor 81. The motor 81 drives the screw 82 to rotate. The screw 82 drives the lifting block 83 and the lifting plate 2 to move upward. The lifting plate 2 drives the rotating arm 4 to move upward. Stop the adjustment when the center of the rotating arm 4 is consistent with the center height of the sunshade lens cover.

[0033] Insert the latch plate on the rear side of the telescopic arm 5 onto the mirror cover, and ensure that the centers of the two are on the same straight line. Start motor 3. Motor 3 drives the rotating arm 4 and the telescopic arm 5 to rotate. The telescopic arm 5 drives the mirror cover on the surface of the anti-glare sunshade to rotate. The magnetic sensor 6 can be used with external equipment to record the number of rotations of the telescopic arm 5.

[0034] Any aspects not described in detail in this specification are techniques well-known in the art.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
