[0017] 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.

[0018] Example: like Figure 1-12 As shown, this embodiment proposes a testing device for the headlights of new energy vehicles, including a testing frame 10. The testing frame 10 is provided with a top plate 13 and a bottom plate 11, and four sets of support plates 12 are evenly arranged between the top plate 13 and the bottom plate 11. The base plate 11 is provided with a positioning component 50 for holding the car headlights. A sliding plate 40 is provided between the four sets of support plates 12. A counterweight 41 is provided on one end of the sliding plate 40 facing the positioning component 50, so that the sliding plate 40 is lowered towards the base plate 11 under the action of gravity, and the car headlights on the positioning component 50 are subjected to a collision test.

[0019] In this embodiment, when testing the car headlights, the top plate 13, the bottom plate 11 and the four sets of support plates 12 are assembled into an overall test frame 10, ensuring that the four sets of support plates 12 are evenly distributed between the top plate 13 and the bottom plate 11. Then, the positioning component 50 is fixed to the bottom plate 11 with bolts, ensuring that the positioning component 50 is located in the center area of ​​the bottom plate 11, directly below the falling trajectory of the sliding plate 40. The car headlights are then positioned using the positioning component 50. After that, the sliding plate 40 is adjusted to a high point and allowed to fall freely. A collision test is conducted by the contact between the counterweight 41 and the car headlights. The positioning component 50 set on the base plate 11 can reliably position and clamp the headlights of new energy vehicles, effectively limiting the displacement or shaking of the headlights during the crash test, ensuring that the posture and force position of the headlights remain consistent in each test, ensuring the repeatability of the test conditions, and significantly improving the credibility and effectiveness of the crash test results. The collision execution structure formed by the sliding plate 40 and the counterweight 41 uses gravity drive to complete the collision test of the vehicle headlights. It does not rely on complex electric or hydraulic power mechanisms, which not only greatly simplifies the overall structure of the device, but also reduces the manufacturing cost and the difficulty of later maintenance. At the same time, the guiding constraint of the sliding plate 40 by the four sets of support plates 12 can ensure that the sliding plate 40 falls stably along the preset trajectory, so that the collision force and collision position of the counterweight 41 on the vehicle headlights are precisely controllable, further improving the accuracy and repeatability of the test results.

[0020] Specifically, the support plate 12 is provided with guide grooves 121, and the four sets of guide grooves 121 are arranged toward the center of the base plate 11. The four corners of the sliding plate 40 are respectively slidably arranged in the four sets of guide grooves 121. The test frame 10 is also equipped with three sets of protective plates 30, which are located between the bottom plate 11 and the top plate 13. The three sets of protective plates 30 are arranged in a C-shape. The test frame 10 is also connected to a protective door 20 by a hinge.

[0021] In this embodiment, the guide groove 121 can form a precise guiding constraint on the sliding plate 40, effectively limiting the movement trajectory of the sliding plate 40, and preventing the sliding plate 40 from moving up and down along the support plate 12, especially during gravity-driven descent to perform a collision test, causing lateral deviation, swaying or tilting, ensuring that the sliding plate 40 always moves stably along a preset vertical direction or a preset path adapted to the requirements of the vehicle headlight collision test.

[0022] Specifically, the top plate 13 has a connecting through hole 131, and the top of the sliding plate 40 is provided with a connecting rope 42, which is connected to an external electric hoist.

[0023] In this embodiment, the connecting through hole 131 on the top plate 13 provides a precise path for the connecting rope 42 at the top of the sliding plate 40 to pass through and guide, effectively limiting the direction of the connecting rope 42 and preventing the connecting rope 42 from shifting laterally, getting tangled, or interfering with other components of the device such as the support plate 12 during the lifting and lowering process of the sliding plate 40. This ensures the stability and smoothness of the power transmission from the connecting rope 42 to the sliding plate 40, and provides a structural basis for the controllable movement of the sliding plate 40. The sliding plate 40 is connected to an external electric hoist via a connecting rope 42. The electric hoist's power output enables controllable lifting and lowering of the sliding plate 40. On one hand, it can precisely adjust the sliding plate 40 to a preset test height according to the collision force required for new energy vehicle headlight collision testing. Different heights result in different gravitational potential energy of the sliding plate 40, leading to different collision forces during descent. This meets the testing requirements of headlights with different specifications and collision performance requirements, improving the device's adaptability to diverse testing scenarios. On the other hand, compared to manually lifting the sliding plate 40, the electric hoist driving method avoids height control errors caused by manual operation, while significantly reducing the labor intensity of operators and improving test preparation efficiency.

[0024] Specifically, the positioning component 50 includes a positioning mounting plate 51, which is connected to the base plate 11 by bolts; The positioning mounting plate 51 has an adjustment groove 511. The two ends of the positioning mounting plate 51 are provided with side plates 512 connected by bolts. The adjustment groove 511 is located between two sets of side plates 512. The adjustment groove 511 is provided with two sets of first adjustment blocks 53 and second adjustment blocks 54 that move in opposite directions.

[0025] In this embodiment, the positioning mounting plate 51 is connected to the base plate 11 by bolts. On the one hand, this ensures that the positioning component 50 does not shift or loosen during the collision test of the new energy vehicle headlights, thus ensuring the clamping stability of the positioning component 50 on the headlights. On the other hand, the detachable connection structure facilitates the subsequent disassembly, maintenance, or replacement of the positioning component 50 according to test requirements, thereby improving the overall operation and maintenance flexibility of the device. Of course, the adjustment groove 511 opened on the positioning mounting plate 51, together with the side plates 512 set on both sides of the adjustment groove 511, forms a double constraint structure for the first adjustment block 53 and the second adjustment block 54. The adjustment groove 511 limits the movement trajectory of the first adjustment block 53 and the second adjustment block 54, so as to prevent the first adjustment block 53 and the second adjustment block 54 from shifting laterally, flipping or deviating from the preset movement path during the adjustment process, so as to perform positioning processing on the car headlights.

[0026] Specifically, the first adjusting block 53 is provided with a first threaded sleeve 531, and the second adjusting block 54 is provided with a second threaded sleeve 541. The first adjusting block 53, the second adjusting block 54, the first threaded sleeve 531 and the second threaded sleeve 541 are all slidably disposed in the adjusting groove 511. An adjusting rod 52 is provided between the two sets of side plates 512. The adjusting rod 52 has two sets of external threaded walls 521 with opposite thread directions. The first threaded sleeve 531 and the second threaded sleeve 541 are respectively provided on the two sets of external threaded walls 521.

[0027] In this embodiment, two sets of external threaded walls 521 with opposite thread directions on the adjusting rod 52 form threaded engagements with the first threaded sleeve 531 of the first adjusting block 53 and the second threaded sleeve 541 of the second adjusting block 54, respectively. When the adjusting rod 52 is rotated, the two sets of external threaded walls 521 can simultaneously drive the first threaded sleeve 531 and the second threaded sleeve 541 to move in opposite directions, thereby driving the first adjusting block 53 and the second adjusting block 54 to achieve synchronous displacement in opposite directions within the adjusting groove 511, so as to clamp and position the car headlights through the first adjusting block 53 and the second adjusting block 54.

[0028] Specifically, the first adjusting block 53 is provided with a first clamping plate 532, the first clamping plate 532 is provided with a first rotating rod 533, the first rotating rod 533 is rotatably mounted on the first adjusting block 53, and the first clamping plate 532 is provided with a first rubber pad. The second adjusting block 54 is provided with a second clamping plate 542, the second clamping plate 542 is provided with a second rotating rod 544, the second rotating rod 544 is rotatably mounted on the second adjusting block 54, and the second clamping plate 542 is provided with a second rubber pad. The first rotating rod 533 and the second rotating rod 544 are coaxially arranged.

[0029] In this embodiment, the rotational engagement of the first rotating rod 533 with the first adjusting block 53 and the rotational engagement of the second rotating rod 544 with the second adjusting block 54 allows the first clamping plate 532 to rotate flexibly around the axis of the first rotating rod 533 and the second clamping plate 542 to rotate flexibly around the axis of the second rotating rod 544. This allows the position of the car headlight after it has been clamped to be adjusted to improve the quality of the test.

[0030] Specifically, a rotating disk 543 is fixedly installed on the second rotating rod 544; The second adjustment block 54 has a limiting cavity 545, and an elastic limiting block 60 is provided in the limiting cavity 545. The elastic limiting block 60 contacts the rotating disk 543, so that the second rotating rod 544 is positioned on the second adjustment block 54.

[0031] In this embodiment, the elastic limiting block 60 and the rotating disk 543 can be elastically abutted together to apply a continuous and stable positioning constraint force to the second rotating rod 544, effectively limiting the second rotating rod 544 from unexpected rotation in the non-operational state, thereby ensuring that the collision area of ​​the car headlight is in a fixed state.

[0032] Specifically, a limiting arc-shaped groove 546 is provided in the limiting cavity 545; The elastic limiting block 60 is provided with a limiting rod 61, which is rotatably disposed in the limiting cavity 545. The elastic limiting block 60 is also provided with a supporting spring 63, which is disposed in the limiting arc groove 546.

[0033] Specifically, the rotating disk 543 has multiple sets of rotating notches 5431, and the multiple sets of rotating notches 5431 are arranged in a ring array; The elastic limiting block 60 is provided with a limiting protrusion 62, which is placed in the rotation notch 5431, so that the second rotating rod 544 is positioned on the second adjusting block 54.

[0034] In this embodiment, when positioning the car headlight, the first adjusting block 53 and the second adjusting block 54 are displaced to clamp the car headlight between the first rubber pad and the second rubber pad. Then, the elastic limiting block 60 is pressed, causing the elastic limiting block 60 to rotate around the axis of the limiting rod 61, causing the limiting protrusion 62 to disengage from the rotating notch 5431. The rotating disk 543 is then turned to make the car headlight rotate around the axis of the first rotating rod 533 and the second rotating rod 544, adjusting the area to be detected towards the counterweight 41. Then, the pressure on the elastic limiting block 60 is released, and under the elastic reset of the support spring 63, the limiting protrusion 62 is driven back into the rotating notch 5431 to restrict the rotating disk 543.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
