Description

Technical Field

[0001] This utility model relates to the field of vibration detection technology for vehicle-mounted displays, and in particular to a device for testing the vibration performance of vehicle-mounted displays. Background Technology

[0002] Vibration resistance testing of in-vehicle displays is a test conducted on displays installed inside vehicles to evaluate their reliability and durability under different vibration conditions. This test is crucial to ensuring that in-vehicle displays can function properly in various driving environments. However, vehicles inevitably encounter various complex road conditions during driving, such as bumpy roads, high-speed turns, and vibrations generated when passing through bridges or tunnels.

[0003] Current methods for testing the vibration resistance of vehicle displays typically involve fixing the display to a testing device and then generating vibrations through that device. However, current testing devices cannot adjust for different vibration amplitudes, making it difficult to simulate the vibrations generated by vehicles under different road conditions. This can lead to discrepancies between the test results and actual usage, making it difficult to accurately assess the true vibration resistance of the display.

[0004] Therefore, it is necessary to design a vehicle display screen vibration resistance testing device that can detect vehicle display screens through different vibration amplitudes, so as to simulate the vibration generated by vehicles under different road conditions and ensure the reliability of the test. Utility Model Content

[0005] To overcome the shortcomings of current testing devices, which cannot adjust different vibration amplitudes and are not convenient for simulating the vibration of vehicles under different road conditions, thus potentially leading to deviations between test results and actual usage conditions and making it difficult to accurately assess the true vibration resistance of the display screen, this utility model provides a vehicle display screen vibration resistance testing device that can test vehicle display screens through different vibration amplitudes, facilitates the simulation of vehicle vibration under different road conditions, and ensures the reliability of the test.

[0006] The technical solution of this utility model is: a vehicle display screen vibration resistance testing device, including a support frame, a circular track, a first motor, a rotating frame, a drive component, a detection component, and a clamping component. The circular track is connected to the middle of the support frame, and the first motor is connected to the inner side of the lower part of the support frame. The rotating frame is connected to the output shaft of the first motor. The rotating frame is rotatably connected to the circular track. The rotating frame is provided with a drive component that can drive the vehicle display screen. A detection component that can detect the vehicle display screen through different vibration amplitudes is provided between the drive component and the support frame. The detection component is provided with a clamping component that can clamp and fix different vehicle display screens.

[0007] Furthermore, the drive assembly includes a second motor, a lead screw, and a guide rod. The second motor is connected to the lower front part of the rotating frame, and the lead screw is connected to the output shaft of the second motor. The lead screw is rotatably connected to the rotating frame, and the guide rod is connected to the lower rear part of the rotating frame.

[0008] Furthermore, it also includes a detection component, which includes an adjustment frame, a placement platform, a slide rod, pulleys, and a telescopic spring. The adjustment frame is slidably connected to the guide rod and is threadedly connected to a common lead screw. The adjustment frame passes through the lower part of the rotating frame. The support frame is slidably connected to slide rods on all four sides (front, back, left, and right). The placement platform is connected between the upper sides of the slide rods. The lower part of each slide rod is rotatably connected to a pulley, which contacts the adjustment frame. The placement platform is connected to the support frame on all four sides (front, back, left, and right).

[0009] Furthermore, the adjustment frame has a wedge-shaped structure on all four sides (front, back, left, and right).

[0010] Furthermore, it also includes a clamping assembly, which includes a first bidirectional lead screw, a sliding frame, a second bidirectional lead screw, and clamping blocks. The first bidirectional lead screw is rotatably connected to the lower part of the placement platform. Two sliding frames are threadedly connected to the first bidirectional lead screw. The sliding frames are slidably connected to the placement platform. The parts of the sliding frames that are far apart from each other are rotatably connected to the second bidirectional lead screw. Two clamping blocks are threadedly connected to the second bidirectional lead screw. The clamping blocks are slidably connected to the adjacent sliding frames.

[0011] Furthermore, both the first and second bidirectional lead screws are equipped with knobs.

[0012] The beneficial effects are: 1. This utility model uses the rotation of a common lead screw to move the adjustment frame upward. The greater the distance the adjustment frame can squeeze the pulley upward, the greater the deformation of the telescopic spring, and the greater the vibration amplitude generated by the placement platform. This achieves the effect of being able to detect the vehicle display screen through different vibration amplitudes, which is convenient for simulating the vibration of the vehicle under different road conditions and ensuring the reliability of the detection.

[0013] 2. This utility model rotates the first bidirectional lead screw, causing the sliding frame to move under the action of the thread, so that the sliding frame moves closer to each other to clamp the left and right sides of the vehicle display screen. Then, the second bidirectional lead screw is rotated, causing the clamping block to move under the action of the thread, so that the clamping block clamps the front and rear sides of the vehicle display screen. This achieves the effect of clamping and fixing different vehicle display screens, which can easily adapt to different usage needs. Attached Figure Description

Detailed Implementation

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] A device for testing the vibration resistance of a vehicle-mounted display screen, such as Figures 1-3 As shown, it includes a support frame 1, a circular track 2, a first motor 3, a rotating frame 4, a drive assembly, a detection assembly, and a clamping assembly. The circular track 2 is connected to the middle of the support frame 1, and the first motor 3 is connected to the inner side of the lower part of the support frame 1. The rotating frame 4 is connected to the output shaft of the first motor 3. The rotating frame 4 is rotatably connected to the circular track 2. The rotating frame 4 is equipped with a drive assembly, and a detection assembly is provided between the drive assembly and the support frame 1. The detection assembly is equipped with a clamping assembly.

[0022] like Figure 2 and Figure 3 As shown, the drive assembly includes a second motor 5, a common lead screw 6, and a guide rod 7. The second motor 5 is connected to the lower front part of the rotating frame 4. The common lead screw 6 is connected to the output shaft of the second motor 5. The common lead screw 6 is rotatably connected to the rotating frame 4. The guide rod 7 is connected to the lower rear part of the rotating frame 4.

[0023] like Figures 1-3As shown, it also includes a detection component, which includes an adjustment frame 8, a placement platform 9, a slide rod 10, a pulley 11, and a telescopic spring 12. The adjustment frame 8 is slidably connected to the guide rod 7. The adjustment frame 8 has a wedge-shaped structure in all four directions (front, back, left, and right). The adjustment frame 8 is threadedly connected to a common lead screw 6. The adjustment frame 8 passes through the lower part of the rotating frame 4. The support frame 1 has slide rods 10 slidably connected in all four directions (front, back, left, and right). The placement platform 9 is connected between the upper sides of the slide rods 10. The pulleys 11 are rotatably connected to the lower part of the slide rods 10. The pulleys 11 are all in contact with the adjustment frame 8. The placement platform 9 is connected to the support frame 1 in all four directions (front, back, left, and right).

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes a clamping assembly, which includes a first bidirectional lead screw 13, a sliding frame 14, a second bidirectional lead screw 15, and clamping blocks 16. The first bidirectional lead screw 13 is rotatably connected to the lower part of the placement platform 9. Two sliding frames 14 are threadedly connected to the first bidirectional lead screw 13. Both sliding frames 14 are slidably connected to the placement platform 9. The parts of the sliding frames 14 that are far apart from each other are rotatably connected to the second bidirectional lead screw 15. Both the first bidirectional lead screw 13 and the second bidirectional lead screw 15 are provided with knobs for easy gripping and rotation. Two clamping blocks 16 are threadedly connected to the second bidirectional lead screw 15. Both clamping blocks 16 are slidably connected to the adjacent sliding frames 14.

[0025] When using this device, first place the support frame 1 in the vibration resistance testing area of ​​the vehicle display screen, then place the vehicle display screen on the placement platform 9. Next, rotate the first bidirectional lead screw 13 by turning the knob, causing the sliding frame 14 to move under the action of the thread, bringing the sliding frames 14 closer together to clamp the left and right sides of the vehicle display screen. Then rotate the second bidirectional lead screw 15, causing the clamping blocks 16 to move under the action of the thread, bringing the clamping blocks 16 closer together to clamp the front and rear sides of the vehicle display screen. This allows for clamping and fixing different vehicle display screens, adapting to different usage needs. After fixing, start the first motor 3, driving the rotating frame 4 and the adjusting frame 8 to rotate, causing the pulley 11 to rotate. When the pulley 11 contacts the adjusting frame 8, the four sides of the adjusting frame 8 are wedge-shaped structures, causing the adjusting frame 8 to squeeze the pulley 11 upwards, driving the sliding rod 10 upwards, and the extension spring 12 is subjected to... The compression and contraction cause the vehicle display screen on the placement platform 9 to move upward. When the pulley 11 no longer contacts the adjusting frame 8, the telescopic spring 12 returns to its original state, causing the slide rod 10 to move downward, so that the pulley 11 contacts the rotating frame 4. The adjustment frame 8 rotates and repeatedly compresses the pulley 11, causing the placement platform 9 to move up and down for vibration performance testing. When it is necessary to adjust the vibration amplitude, the second motor 5 can be started, driving the ordinary lead screw 6 to rotate, so that the adjusting frame 8 moves upward along the guide rod 7 under the action of the thread. The more distance the adjusting frame 8 can compress the pulley 11 and move upward, the greater the deformation of the telescopic spring 12, and thus the greater the vibration amplitude generated by the placement platform 9. Then, by rotating the adjusting frame 8 and compressing the pulley 11, the placement platform 9 is moved up and down, so that the vehicle display screen can be tested through different vibration amplitudes, which is convenient for simulating the vibration of the vehicle under different road conditions and ensuring the reliability of the test.
