[0035] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0036] Example:

[0037] See also Figure 1 and Figure 2A testing device for vehicle-mounted multimedia equipment includes a box body 1, a door panel 2, a workbench 3, a supporting cylinder 4 and an air conditioning system 5. Specifically, the box body 1 is a square structure with a hollow structure inside, and a door panel 2 is provided on the front of the box body 1, and a control panel 11 is provided on the door panel 2.

[0038] There are four supporting cylinders 4, all of which are vertically arranged on the bottom surface of the box body 1. The four supporting cylinders 4 are respectively close to a corner of the box body 1, and the piston rods of the four supporting cylinders 4 are vertically upward.

[0039] A workbench 3 is placed on top of the four supporting cylinders 4. In the initial state, the piston rods of the four supporting cylinders 4 extend to the same extent, so that the top surface of the workbench 3 is on a horizontal plane. There is a gap between the four sides of the workbench 3 and the four sides of the box 1, and there is also a gap between the four supporting cylinders 4 and the four corners of the bottom surface of the workbench 3.

[0040] The air conditioning system 5 is arranged on the box body 1 , wherein the indoor unit of the air conditioning system 5 is arranged on the top surface inside the box body 1 , and the outdoor unit of the air conditioning system 5 is arranged on the back surface outside the box body 1 .

[0041] In this embodiment, the valve controllers of the four supporting cylinders 4 are connected to the control panel 11, and the air conditioning system 5 is also connected to the control panel 11. A processor and a touch-sensitive display are provided in the control panel 11. The charging and discharging of the four supporting cylinders 4 and the output temperature of the air conditioning system 5 can be directly controlled through the control panel 11.

[0042] During operation, the workbench 3 is set in the box 1, and the in-vehicle multimedia device to be tested is fixed on the workbench 3. Since four supporting cylinders 4 are arranged between the bottom surface of the workbench 3 and the inner bottom surface of the box 1, the four supporting cylinders 4 are controlled to extend and retract in a random order through the control panel 11, so as to control the four corners of the workbench 3 to be randomly lifted or lowered, thereby simulating the vibration of the in-vehicle multimedia device when the vehicle is driving on a road with complex road conditions.

[0043] In addition, the temperature in the box 1 is regulated by the air conditioning system 5 disposed on the box 1 to simulate the working state of the vehicle-mounted multimedia device in different seasons or climates in different regions.

[0044] In this technical solution, more accurate test data is obtained by simulating the state of the vehicle-mounted multimedia device in different temperature environments and disordered vibration environments.

[0045] In one specific embodiment:

[0046] The top end of the piston rod of the support cylinder 4 is a raised spherical structure, so that the contact surface between the top surface of the piston rod of the support cylinder 4 and the bottom surface of the workbench 3 is a curved surface. Therefore, when the four support cylinders 4 drive the workbench 3 to vibrate in a disorderly manner, the top end of the piston rod of the support cylinder 4 and the bottom surface of the workbench 3 can maintain a smooth connection state, thereby avoiding loud noise and reducing the wear rate of the bottom surface of the workbench 3.

[0047] In another specific embodiment:

[0048] The testing device further comprises a support rod 6, a sphere 7 and a support block 8. The support rod 6 is fixedly arranged on the bottom surface of the workbench 3 and located in the middle of the workbench 3, and the length direction of the support rod 6 is arranged along the vertical direction.

[0049] A sphere 7 is arranged on the bottom end of the support rod 6 (the end away from the workbench 3), and the center of the sphere 7 is projected on the bottom surface of the workbench 3 at the center of the workbench 3. The diameter of the sphere 7 is larger than the circumscribed circle of the bottom end face of the support rod 6.

[0050] The support block 8 is arranged on the bottom surface of the inner side of the box body 1, and the top surface of the support block 8 has a movable part, which is a concave spherical structure. The diameter of the spherical structure is equal to the diameter of the sphere 7, and the central angle of the spherical structure is greater than or equal to 180°.

[0051] The top of the sphere 7 is connected to the support rod 6, and the bottom of the sphere 7 is embedded in the movable part of the top surface of the support block 8. The sphere 7 can rotate freely in the movable part. Generally, lubricant is filled in the movable part.

[0052] In this embodiment, a support rod 6 is provided and a sphere 7 is provided at the bottom end of the support rod 6, so that the sphere 7 can be movably provided on the top surface of the support block 8, thereby controlling the lateral movement range of the workbench 3 through this structure, so that the workbench 3 can only rotate a certain angle around the center of the sphere 7 under the drive of the four supporting cylinders 4, thereby avoiding collision between the outer periphery of the workbench 3 and the inner wall of the box body 1.

[0053] In another specific embodiment:

[0054] The support block 8 is slidably disposed on the bottom surface of the inner side of the box body 1. A linear cylinder 9 is also disposed on the bottom surface of the inner side of the box body 1. The piston rod end of the linear cylinder 9 is connected to one side of the support block 8. The linear cylinder 9 is arranged in the horizontal direction. By slidably disposing the support block 8 on the bottom surface of the box body 1 and driving the support block 8 to slide on the bottom surface of the box body 1 by the linear cylinder 9, the lateral vibration of the vehicle during driving is simulated.

[0055] Through the cooperation of the linear cylinder 9 and the supporting cylinder 4, the workbench 3 can make irregular rotations around the center of the sphere 7 during the lateral vibration, thereby simulating the complex vibration environment during vehicle driving, thereby obtaining more accurate test data for the vehicle-mounted multimedia equipment.

[0056] Preferably, two rails 10 are provided in parallel on the inner bottom surface of the box body 1, and the support block 8 is slidably provided on the rails 10. The length direction of the rails 10 is consistent with the length direction of the linear cylinder 9. By providing the rails 10, the moving track of the support block 8 is limited.

[0057] In another specific embodiment:

[0058] A door frame is provided on the front of the box 1, and two door panels 2 are symmetrically provided in the door frame, and a control panel 11 is provided on one of the door panels 2. The door frame is close to the top of the box 1, and the height of the door frame is less than the distance between the top surface of the workbench 3 and the top surface of the box 1. By providing the door frame, it is convenient to install the door panel 2, and the door frame is arranged near the top of the box 1, so as to avoid the parts below the workbench 3 being exposed to the outside, and reduce the safety hazards when installing the vehicle multimedia device on the workbench 3.

[0059] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
