Description

Technical Field

[0001] This utility model relates to the technical field of lighting testing, and in particular to a lighting testing stand for electric vehicle lamps. Background Technology

[0002] Lighting test benches, or simply test benches, are the foundation of electronic equipment testing. They are mainly used to verify whether the design, performance, and quality of lighting fixtures meet relevant standards and requirements. However, one type of existing electric vehicle lighting test bench involves manually connecting the power supply to the lighting fixture and then using a camera to capture the light emitted by the fixture to determine its qualification. However, because the surfaces of the lighting fixtures are irregularly curved, the fixtures are unstable when placed on the test bench, making the power connection process cumbersome. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a test bench for electric vehicle lighting fixtures, which solves the technical problem of instability when the lighting fixtures are placed on the test bench, thereby improving the overall testing efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an electric vehicle lamp lighting test stand, including a support platform as a support base, a convenient pressing and clamping mechanism for clamping and fixing the lamp to be tested, and a light-shielding detection mechanism for guiding and shading the lamp.

[0005] The convenient pressing and clamping mechanism includes a placement platform located at the center of the top of the support platform. A guide rod is fixedly connected to the placement platform. Several flipping teeth are rotatably connected to the lower side of the guide rod on the outer side of the support platform. A limiting tooth that meshes with the flipping teeth is slidably connected to the support platform via a sliding rod. Three support frames are fixedly connected at equal intervals around the top of the support platform on the outer side of the placement platform. A flipping rod is rotatably connected to the support frame. A clamping seat is rotatably connected to the top of the flipping rod. The end of the connecting rod away from the support frame is rotatably connected to the outer side of the placement platform.

[0006] Preferably, a return spring is connected between the placement platform and the support platform, and the guide rod is slidably connected to the support platform.

[0007] Preferably, each of the clamping seats has a limit spring connected to both ends, and the other end of the limit spring is connected to the outer wall of the adjacent flipping rod.

[0008] Preferably, the light-shielding detection mechanism includes a light-shielding cover fixedly connected to the top of the support platform, and the top of the light-shielding cover has a placement groove for placing lamps.

[0009] Preferably, the inner side of the placement groove is equidistantly connected with limiting arc plates, and the gaps between the three limiting arc plates correspond to the clamping seats respectively.

[0010] Preferably, a storage compartment is fixedly connected to the outside of the support platform, and a data acquisition camera is installed inside the storage compartment via a base. The signal output terminal of the data acquisition camera is connected to the power input terminal of an external control terminal.

[0011] By employing the above technical solution, this utility model provides a lighting test bench for electric vehicle lamps, which has at least the following beneficial effects:

[0012] 1. Due to the convenient pressing and clamping mechanism, this utility model makes the placement and fixing of lamps more convenient. By pressing, the clamping component is retracted, thereby clamping the outside of the lamp. The clamping component is limited by the cooperation of the flipping teeth and the limiting teeth, thereby speeding up the fixing process of the lamp.

[0013] 2. Due to the setting of the light-shielding detection mechanism, this utility model can shield the environment around the lamp to be tested, thereby making the light source detection results of the acquisition camera more accurate, avoiding interference from natural light, and guiding the lamp during the lamp placement stage so that the lamp can accurately enter the inside of the convenient pressing and clamping mechanism.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Because the surfaces of the lamps are irregularly curved, they are unstable when placed on the testing rack, making the power connection process cumbersome. Please refer to... Figures 1-3 This embodiment provides a lighting test bench for electric vehicle lamps, solving the technical problem of unstable lamp placement on the test bench. The device includes a support platform 1 as a supporting base, a convenient pressing and clamping mechanism 2 for clamping and fixing the lamp to be tested, and a light-shielding detection mechanism 3 for guiding and shielding the lamp. The lamp is clamped and fixed by the convenient pressing and clamping mechanism 2, and the lamp is shielded and tested by the light-shielding detection mechanism 3.

[0025] In practice, due to differences in specifications and the arc-shaped surface of actual lamps, it is difficult to quickly fix and limit the lamps, which affects the subsequent power connection and testing of the lamps. Therefore, a convenient pressing and clamping mechanism 2 is proposed to solve this problem. The convenient pressing and clamping mechanism 2 includes a placement platform 201 set at the middle of the top of the support platform 1. A guide rod 203 is fixedly connected to the placement platform 201. Several flip teeth 204 are rotatably connected to the lower side of the guide rod 203 on the outer side of the support platform 1. A limiting tooth 210 that meshes with the flip teeth 204 is slidably connected to the support platform 1 through a sliding rod. Three support frames 205 are fixedly connected at equal intervals around the top of the support platform 1 on the outer side of the placement platform 201. A flip rod 206 is rotatably connected to the support frame 205. A clamping seat 207 is rotatably connected to the top of the flip rod 206. The end of the connecting rod 209 away from the support frame 205 is rotatably connected to the outer side of the placement platform 201. A reset spring 202 is connected between the placement platform 201 and the support platform 1. The guide rod 203 is slidably connected to the support platform 1. Several clamping seats 207 are connected to limit springs 208 at both ends. The other end of the limit spring 208 is connected to the outer wall of the nearby flipping rod 206.

[0026] The operator places the lamp on top of the placement platform 201, and then presses down on the placement platform 201. At this time, the placement platform 201 will slide down through the pull rod 203 fixedly connected to its bottom end. As the placement platform 201 moves downward, the connecting rod 209 rotatably connected to it will flip towards the placement platform 201, and at the same time drive the flipping rod 206 rotatably connected to it to flip towards the placement platform 201. The clamping seat 207 rotatably connected to the top of the flipping rod 206 will also retract inward to clamp until all the clamping seats 207 are clamped on the outside of the lamp. At this time, the operator reduces the pressure on the placement platform 201. At this time, the return spring 202 at the bottom of the placement platform 201 will drive the placement platform 201 and the pull rod 203 connected to it to slide upward. At this time, the flipping tooth 204 rotatably connected to the lower side of the pull rod 203 will engage with the limiting tooth 210, thereby realizing the positioning of the clamping component.

[0027] Example 2

[0028] Based on Example 1, which solved the technical problem of unstable lamp placement on the test bench, Example 1 still has the problem that external light can affect the test results during testing. Figures 1-3 As shown, the specific implementation process is as follows: In actual operation, the detection equipment may produce incorrect detection data due to the influence of natural light. To avoid this situation, a light-shielding detection mechanism 3 is proposed. The light-shielding detection mechanism 3 includes a light-shielding cover 301 fixedly connected to the top of the support platform 1. A placement slot 302 for placing lamps is opened in the middle of the top of the light-shielding cover 301. Limiting arc plates 303 are fixedly connected at equal intervals around the inner side of the placement slot 302. The gaps between the three limiting arc plates 303 correspond to the clamping seats 207 respectively. A storage compartment 304 is fixedly connected to the outer side of the support platform 1. A data acquisition camera 305 is installed on the inner side of the storage compartment 304 through the base. The signal output terminal of the data acquisition camera 305 is connected to the power input terminal of the external control terminal.

[0029] During this period, the placement slot 302 and the limiting arc plate 303 at the top of the light shield 301 can improve the guidance and stability of the lamp when it is placed into the convenient pressing and clamping mechanism 2. After the lamp is clamped and fixed, the operator connects the power supply of the lamp and then turns on the lamp and the acquisition camera 305. At that time, the light shield 301 will reduce the influence of the outside natural light and detect and record the light source of the lamp, thereby determining whether the lamp is qualified.
