[0002] Vehicle instrument panels are devices that reflect the operating status of various vehicle systems. They typically consist of a speedometer and an odometer, which can visually display the vehicle's speed and record the cumulative mileage. To ensure the quality of vehicle instrument panels, they undergo aging tests before leaving the factory. Aging tests usually include vibration and temperature. In current technology, most aging tests can only simulate one aspect, and vibration simulation is usually done by moving the instrument panel up and down, which cannot fully simulate the vibration experienced by the vehicle instrument panel. Utility Model Content

[0003] This invention proposes an instrument aging test device that can not only simulate temperature and vibration simultaneously, but also comprehensively simulate the vibration experienced by vehicle instruments from all angles (up, down, left, and right).

Detailed Implementation

[0014] The present invention will be further described below with reference to embodiments and accompanying drawings: like Figures 1-3As shown, an instrument aging test device mainly consists of a test chamber 10, an instrument rack 20, a sealing door, a vibration structure, and an air circulation structure. The instrument rack is used to install several instrument units. A receiving groove 11 for accommodating at least one instrument rack is provided inside the test chamber 10, and the receiving groove 11 is arranged through the front and back. Sealing doors that are transparent and seal the receiving groove are provided on the front and back sides of the test chamber 10. A vibration structure for supporting the instrument rack and enabling the instrument rack to move up, down, left, and right is provided at the bottom of the receiving groove 11. An air circulation structure for changing the temperature inside the receiving groove is provided inside the test chamber 10.

[0015] The vibration structure includes a vibration motor 41 housed inside the receiving groove 11 and two horizontally spaced drive shafts 42. A synchronous belt structure 43 is provided between the two drive shafts 42. A power transmission structure 44 is provided between the vibration motor 41 and the drive shafts 42. Each drive shaft 42 has a transmission seat 45 at both ends for supporting the drive shaft. After passing through the corresponding transmission seat, each end of the drive shaft 42 has a cam block 46. The bottom of the instrument frame 20 has four downwardly extending support rods 21 arranged in a rectangular pattern. Each support rod 21 is connected to the corresponding cam block 46 by a pin, meaning the pin does not coincide with the axis of the drive shaft, allowing the cam block to function as a connecting rod. Bearings are provided between the support rods 21 and the pins. The power transmission structure uses existing technologies such as belt transmission, and the synchronous belt structure is also existing technology, which will not be described in detail here.

[0016] During operation, the vibration motor operates, and the rotation of two drive shafts is achieved through a power transmission structure and a synchronous belt structure. This rotation drives four cam blocks to rotate. Since the support rod is connected to the cam blocks by a pin, the pin moves in an elliptical shape, thus causing the support rod and instrument frame to move in an elliptical motion. Because a bearing is installed between the support rod and the pin, the pin rotates while the support rod does not. The entire vibration structure is simple and can achieve elliptical movement of the instrument frame in all directions, making it more realistically simulate the vibration conditions it experiences.

[0017] Preferably, a protective cover 50 for protecting the vibrating structure is provided below the instrument frame 20. The protective cover includes baffles located on the front, rear, left, and right sides of the vibrating motor, and the distance between the baffles and the instrument frame is small. Since an air circulation structure is provided, it is preferable that the vibrating motor adopts a high-temperature resistant structure based on existing technology.

[0018] The air circulation structure includes several air outlets located on the inner left side of the receiving tank and several air inlets located on the inner side of the receiving tank. An air outlet sluice connected to all the air outlets is located on the left side of the test chamber located in the receiving tank, and an air inlet sluice connected to all the air inlets is located on the right side of the test chamber located in the receiving tank. An air circulation pipe is provided between the air outlet sluice and the air inlet sluice. A temperature detection sensor for detecting the temperature of the inlet and outlet air, a heater for heating the air, and a circulation pump for realizing air circulation are provided on the air circulation pipe.

[0019] Preferably, the instrument frame 20 is designed with a tapered structure, and both the left and right sides of the instrument frame 20 are provided with mounting slots for instrument units, so that instrument units can be installed on both the front and rear sides of the instrument frame, increasing the number of instruments that can be tested on one side. The instrument unit 30 includes a mounting plate 31 that can be installed on the mounting slot, and each mounting plate 31 is provided with a clamping cylinder 32 for clamping the instrument.
