Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive headlight testing technology, and in particular to a device for testing the function of a light shield. Background Technology
[0002] Car headlights have two modes: low beam and high beam. High beam is the high beam mode. Traffic regulations clearly define the use of high beams, as they can bring convenience and safety when used correctly, but incorrect use can pose significant safety hazards. The control of high and low beams is achieved through the headlight visor.
[0003] Currently, the functional testing of sun visors is mainly done manually. The usual method is to directly connect the motor on the sun visor to the power supply, focusing only on whether the sun visor can open and close. Of course, the power supply is usually a regulated power supply. This kind of test data is relatively crude and cannot clearly detect whether the sun visor is fully open or fully closed, or whether the sun visor has shifted. At the same time, because this crude test method cannot determine whether the sun visor is compliant, it will bring great hidden dangers to safe driving. Summary of the Invention
[0004] To address the problems of existing technologies, embodiments of the present invention provide a sunshade function testing device that can accurately detect the operating status of sunshades, thereby ensuring safe driving.

That is, this embodiment realizes all-round detection of the movement state of the light shield, further ensuring driving safety.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0020] refer to Figure 1As shown, a light-shielding plate function testing device includes a control device 18, a testing device, and a workpiece positioning workpiece. The testing device and the workpiece positioning workpiece are disposed on the upper surface of the housing of the control device and are respectively connected to the control device. The control device 18 is equipped with a display 11 and a transformer. The testing device includes a first testing element 14 disposed directly in front of the positioning workpiece, and a second testing element 13 and a third testing element 15 disposed on both sides of the first testing element 14. The first testing element 14, the second testing element 13, and the third testing element 15 are respectively connected to the control device 18. Specifically, the first detection element 14 is used to detect the movement state of the middle part of the sunshade, the second detection element 13 is mainly used to detect the movement state of one end of the sunshade, and the third detection element 15 is used to detect the movement state of the other end of the sunshade. This embodiment achieves comprehensive detection of the movement state of the sunshade, fully ensuring driving safety. The positioning workpiece includes a main positioning workpiece 19, an auxiliary positioning workpiece 20, and a first cylinder 22. The main positioning workpiece 19 is movably connected to the housing of the control device 18. The auxiliary positioning workpiece 20 is equipped with a power supply connected to the control device. The first cylinder 22 is connected to the auxiliary positioning workpiece 20. The first cylinder 20 is connected to the housing of the control device via a support 21 mounted on the housing of the control device. Under the action of the first cylinder, the car lamp to be tested, placed on the positioning workpiece, is pushed to the detection mark of the detection device. When the first detection element detects the light shield of the car lamp, the control device is activated to begin functional testing of the light shield of the car lamp. The transformer is connected to the first detection element. Specifically, when the first detection element first detects the middle part of the light shield, the control device and the transformer are turned on. At this time, the output voltage of the transformer is 9V. The light shield begins to open, and the detection device begins to detect its operation at 9V. The functional operation status under voltage is monitored. When the first detection element detects the middle part of the light shield for the second time, that is, when the light shield resets, the first detection unit transmits an adjustment signal to the transformer again. At this time, the output voltage of the transformer is 12.8V, and the light shield is opened again to detect its functional operation status under 12.8V voltage. In this embodiment, the voltage adjustment range of the transformer is 9V-14V, which meets the working voltage requirements of the solenoid valve on the light shield. Under the control of the control device, this technical solution realizes the transformer control detection of the car light under test, ensuring that the light shield can achieve precise high and low beam control within the pressure range required by the solenoid valve, thus ensuring driving safety.
[0021] Specifically, in this embodiment, the first detection element 14, the second detection element 13, and the third detection element 15 are all infrared detectors; it should be noted that the first detection element, the second detection element, and the third detection element in this embodiment can also be laser detectors, depending on the product requirements.
[0022] Furthermore, the control device in this embodiment is also equipped with an alarm light 12, which is located on one side of the display 11. When any of the three detection elements fails to meet the design requirements, an alarm signal will be sent to the control device, and the alarm light will start flashing as a warning.
[0023] Furthermore, this embodiment also includes a coding machine 16 disposed on the housing of the control device and connected to the control device. When the three detection elements detect that the light shield meets the functional design requirements, the control device turns on the coding machine to input the product code on the compliant product.
[0024] Furthermore, this embodiment also includes a second cylinder 17 connected to the coding machine 16, the second cylinder 17 being connected to the control device via a bracket mounted on the housing of the control device.
[0025] Furthermore, the control device described in this embodiment is also equipped with a control button 23.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
