[0002] The instrument panel is an interface on a vehicle or equipment that displays critical information, including speed, RPM, fuel level, temperature, and other important data, helping drivers or operators understand the equipment's operating status in real time. Because the information displayed on the instrument panel is directly related to driving safety and equipment operation, its accuracy and stability are crucial. The instrument panel test device simulates different operating conditions and abnormal situations to ensure that the instrument panel operates accurately and reliably in various environments, thereby avoiding potential safety hazards caused by data errors or failures and ensuring the normal operation of vehicles and equipment.

[0003] Traditional instrument panel testing equipment typically secures the instrument panel to a test bench using mechanical fixtures or bolts, then connects equipment such as a signal simulator and power module. The operator sets input signals based on test requirements, simulating vehicle or equipment operating conditions such as speed, rotational speed, and temperature, to observe the instrument panel display. During this process, test parameters are adjusted manually or semi-automatically, and displayed data is collected and compared with expected values ​​to evaluate the instrument panel's accuracy and performance.

[0004] Traditional instrument panel test devices, due to the diversity and complexity of instrument panel shapes, are usually designed with standardized structures for fixing. They cannot flexibly adapt to the shapes of different instrument panels, and thus cannot maintain a stable position of the instrument panel during testing, resulting in inaccurate alignment of sensors or camera equipment, thereby causing data collection errors and affecting the reliability of test results.

The lower surface of the sliding block 1201 is fixedly connected to the upper surface of the storage box 2. The outer wall of the sliding block 1201 is slidably connected to a guide rail 1202. The outer wall of the guide rail 1202 is fixedly connected to the inside of the test chamber 1;

[0027] Specifically, the instrument panel is first placed on the inner wall of the storage box 2, and then the worm 3 is driven. Due to the meshing relationship between the worm 3 and the worm wheel 4, the worm wheel 4 rotates with the rotation of the worm 3, thereby driving the threaded plate 5 to rotate through the worm wheel 4, and then the threaded plate 5 is meshed with the slider 6, so that the slider 6 slides inside the test chamber 1 with the rotation of the threaded plate 5, and then the slider 6 drives the slide plate 7 to slide on the inner wall of the storage box 2, and then the movement of the slide plate 7 drives the V-shaped bracket 8 and the clamping soft block 9 to move toward the instrument panel, so that the clamping soft block 9 is in contact with the instrument panel.

[0030] Working principle: When the instrument panel test device is needed, first place the instrument panel on the inner wall of the storage box 2, drive the worm 3, and make the worm wheel 4 rotate accordingly, driving the threaded plate 5 to rotate. The slider 6 slides in the test chamber 1 as the threaded plate 5 rotates, and then pushes the slide plate 7 to move on the inner wall of the storage box 2.

The clamping soft block 9 fits with the outer wall of the instrument panel. Under the support of the instrument panel, the V-shaped bracket 8 rotates on the outer wall of the fixed rod 10, causing the torsion spring 11 to twist, and finally the clamping soft blocks 9 at both ends are close to the instrument panel. The outer wall is clamped and fixed. Then, the terminal 14 and the terminal 2 20 are connected to the instrument panel interface, powered by the power supply 13, and the working conditions under actual driving conditions are simulated through the terminal 2 20.
