[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 6 , in this embodiment, a function test bracket for an automotive center control display screen includes a housing 1, a mounting table 2 arranged above the housing 1, and a storage rack 3. A vacuum adsorption device 4 for fixing the automotive center control display screen is arranged on the storage rack 3. A carrying platform 11 is fixedly installed on the outer surface of the storage rack 3, and a liquid collecting tank 12 is opened inside the carrying platform 11. A maintenance outer shell is detachably installed on the back of the housing 1.

[0033] To simulate the vibration function test of the automotive center control display screen, an elastic structure 5 is arranged between the housing 1 and the mounting table 2, and a reciprocating mechanism 6 for triggering the deformation of the elastic structure 5 is arranged inside the housing 1. Specifically, the elastic structure 5 includes a guide rod 501 that slidably penetrates through the inside of the housing 1 and is fixed to the lower surface of the mounting table 2, connecting blocks 502 and contact blocks 504 fixed to the upper and lower ends of the guide rod 501, and a return spring 503 fixed between the connecting block 502 and the housing 1. Through the combination of the return spring 503 and the guide rod 501, the elastic structure 5 can simulate the vibrations generated by different road conditions encountered by the vehicle during driving. This kind of vibration is continuous and adjustable, and can more realistically reflect the stress situation of the display screen during actual use. Among them, the inside of the housing 1 is hollowly arranged, and a perforation for the telescopic movement of the guide rod 501 is opened inside the housing 1. It should be noted that the return spring 503 surrounds the outside of the guide rod 501, and the number of the elastic structures 5 is four, and the four elastic structures 5 are arranged in a rectangular shape.

[0034] Specifically, the reciprocating mechanism 6 includes a rotating shaft 601 with bearings installed inside the housing 1, a turntable 602 fixed to the outer surface of the rotating shaft 601, a reciprocating plate 611 disposed above the turntable 602 and intermittently contacting the abutting block 504, a connecting member disposed between the turntable 602 and the reciprocating plate 611, and a driving structure disposed inside the housing 1 for driving the turntable 602 to rotate. Among them, the connecting member includes an adjusting seat 603 fixed to the outer surface of the turntable 602, a sliding seat 604 slidably installed inside the adjusting seat 603, a connecting rod 605 hinged to one side of the sliding seat 604, and a universal ball joint 606 fixed to the end of the connecting rod 605 away from the sliding seat 604. The universal ball joint 606 is rotatably installed on the lower surface of the reciprocating plate 611. The driving structure includes a driving motor 609 fixed to the inner bottom wall of the housing 1. There is a meshing gear member 610 between the output shaft of the driving motor 609 and the outer surface of the rotating shaft 601. The gear member 610 is composed of two transmission gears of different sizes. The combination of the driving motor 609 and the gear member 610 realizes the automatic rotation of the turntable 602, thereby driving the reciprocating plate 611 to move up and down, triggering the deformation of the elastic structure 5. This automated design not only improves the testing efficiency but also reduces the errors caused by manual operation.

[0035] To further improve the vibration effect, a lead screw 607 is rotatably installed inside the adjusting seat 603. The lead screw 607 threadedly penetrates through the inside of the sliding seat 604. A knob 608 fixed to the end of the lead screw 607 is rotatably installed on one side of the adjusting seat 603. The design of the connecting member in the reciprocating mechanism 6, especially by adjusting the position of the sliding seat 604 inside the adjusting seat 603 through the lead screw 607 and the knob 608, changes the transmission path of the connecting rod 605 and the universal ball joint 606, thereby affecting the stroke and frequency of the reciprocating plate 611. This design allows the tester to flexibly adjust the amplitude and frequency of vibration according to actual needs to meet the requirements of different testing scenarios.

[0036] In addition, by adjusting the knob 608 to change the vibration parameters, the tester can simulate a variety of different vibration scenarios, thereby more comprehensively evaluating the performance and reliability of the display screen under different conditions. This comprehensive testing helps to discover potential problems and defects, providing strong support for the improvement and optimization of the product.

[0037] For the linkage cooperation vibration function test, an infusion mechanism 7 for cooperating with the reciprocating mechanism 6 is further provided inside the housing 1. A spraying member is rotatably installed on the top side of the storage rack 3. The spraying member includes a rotating frame 8 rotatably installed on the top side of the storage rack 3 and a spray pipe 9 fixed to the inner side of the rotating frame 8. A tightening bolt for adjusting the tightness is provided on the storage rack 3. Specifically, the infusion mechanism 7 includes a pump housing 701 fixed to the inner bottom wall of the housing 1 and located below the reciprocating plate 611, valve pipes 702 fixedly connected to the outer surfaces on the left and right sides of the pump housing 701, check valves 703 elastically hinged inside the two valve pipes 702, and a piston 704 reciprocatingly arranged inside the pump housing 701. The infusion mechanism 7 is connected to the reciprocating plate 611 in the reciprocating mechanism 6 through the piston 704 and the piston rod 705, realizing the synchronous progress of vibration and spraying. This means that while the display screen is being vibrated, the spraying member can accurately spray liquid, thus simulating the situation where liquids such as rainwater and muddy water may splash onto the display screen during the driving of the vehicle.

[0038] Among them, a piston rod 705 fixed to the upper surface of the piston 704 and extending outside the pump housing 701 and connected to the reciprocating plate 611 is provided. Infusion pipes 10 are fixed to the separated ends of the two valve pipes 702. The two infusion pipes 10 both extend outside the housing 1, and the two infusion pipes 10 are respectively communicated with the liquid storage tank and the spraying member. It should be noted that the infusion pipe 10 connected to the spray pipe 9 is a flexible pipe.

[0039] The working principle of the above embodiment is as follows:

[0040] First, place the automotive center control display screen on the storage rack 3 and fix it through the vacuum adsorption device 4, and then start the drive motor 609. The drive motor 609 drives the rotating shaft 601 and the turntable 602 to rotate through the gear member 610. As the turntable 602 rotates, through the transmission of the connecting member, the reciprocating plate 611 reciprocates up and down inside the housing 1;

[0041] When the reciprocating plate 611 moves upward, it contacts the abutting block 504 and pushes the abutting block 504 and the guide rod 501 upward, and the return spring 503 is compressed. When the reciprocating plate 611 moves downward, the return spring 503 releases energy and pushes the guide rod 501, the connecting block 502 and the abutting block 504 downward, causing the mounting table 2 and the storage rack 3 to vibrate, simulating the bumpy situation during the driving of the vehicle;

[0042] As the reciprocating plate 611 moves up and down, the plug rod 705 drives the piston 704 to reciprocate inside the pump housing 701. When the piston 704 moves upward, a negative pressure is formed inside the pump housing 701, and liquid is sucked from the liquid storage tank through the valve pipe 702 and the infusion pipe 10. When the piston 704 moves downward, the pressure inside the pump housing 701 increases, and the liquid is pressed through the valve pipe 702 and the infusion pipe 10 into the spraying member including the rotating frame 8 and the spray pipe 9. The liquid is sprayed on the automotive central control display screen through the spray pipe 9 for testing the waterproof performance or cleaning effect of the display screen.

[0043] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technology also belongs to the common knowledge in this field. Therefore, the specific structural composition and working principle are not described in detail in this embodiment.
