Detailed implementation manners

[0025] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0028] Embodiment 1, referring to Figure 1 、Figure 3 , Figure 4 and Figure 6 , which is the first embodiment of the present invention. This embodiment provides a lighting tester for motor vehicle detection.

[0029] A support frame 10, which plays a role in supporting the device; a main body 20 provided on the support frame 10, which can detect external lights; a simulation component 30, including a mounting frame 31 provided at the detection port of the main body 20, a reflecting plate 311 movable on the inner wall of the mounting frame 31, and a transmission member 32 for supporting the reflecting plate 311 to rotate. The transmission member 32 helps to transmit power for the movement of the reflecting plate 311; the transmission member 32 includes a movable seat 321 and an auxiliary seat 322 respectively provided outside the reflecting plate 311, a crank 323 provided on the movable shaft of the auxiliary seat 322, a connecting rod 324 provided at one end of the crank 323, and a push plate 325 provided at one end of the connecting rod 324; the reflecting plate 311 can rotate 30 degrees and 60 degrees respectively around the rotation axis of the movable seat 321. When the reflecting plate 311 rotates, the reflecting plate 311 will move flexibly in the mounting frame 31. The reflecting plate 311 is distributed in an array structure and is installed in the grooves on the four sides inside the mounting frame 31. The transmission member 32 corresponds to the structure of the reflecting plate 311. Its push plate 325 is slidably connected to the simulation component 30. One end of the simulation component 30 is fixedly connected with a push rod. The push plate 325 is movably connected to the connecting rod 324 through a rotating shaft. The connecting rod 324 is then movably connected to the crank 323, and the crank 323 is movably associated with the auxiliary seat 322. The movable seat 321 is fixed to one side of the outer wall of the reflecting plate 311 by bolts, and the movable seat 321 is fixed to the other side of the outer wall of the reflecting plate 311 by bolts. As the reflecting plate 311 moves, it will rotate around the rotation axis of the movable seat 321. During the movement of the movable seat 321, it will also drive the auxiliary seat 322 to move together.

[0030] When in use, when pushing the push rod on one side of the push plate 325, the push rod will drive the push plate 325 to displace. The movement of the push plate 325 further drives the movable seat 321 connected thereto to move. The movable seat 321 drives the crank 323 to move by virtue of its connection with the crank 323. The crank 323 drives the auxiliary seat 322 to move. The auxiliary seat 322 drives the reflecting plate 311 to move. While the reflecting plate 311 moves, it drives the angle of the movable seat 321 to rotate, so that the reflecting plate 311 can accurately adjust the angle.

[0031] In summary, by means of the provided reflector, when the push plate 325 is pushed, the push plate 325 will utilize its connection with the connecting rod 324 to enable the connecting rod 324 to move. The connecting rod 324 transmits the power to the crank rod 323, driving the crank rod 323 to operate. The crank rod 323 further drives the auxiliary seat 322 and the reflector 311 to perform synchronous linkage. Through this precise mechanical linkage design, not only is the stable transmission of power achieved, but also with the aid of the configured movable seat structure, the reflector can achieve precise angle adjustment. Such a setting enables the device to effectively simulate the environment of insufficient external light, making the vehicle headlight test closer to the actual working conditions, thereby significantly enhancing the test adaptability and accuracy of the equipment.

[0032] Example 2, referring to Figure 3 、 Figure 4 and Figure 5 , this is the second embodiment of the present invention. Different from the previous embodiment, it solves the problem of the reset of the push plate.

[0033] A reset member 33 is provided at one end of the push plate 325. The reset member 33 can function to reset the push plate. The reset member 33 includes an installation tube 331. A reset block 332 is slidably connected in a groove inside the installation tube 331. A push rod at one end of the push plate 325 is installed on one side of the reset block 332. The reset block 332 is installed inside the installation tube 331 in a slidable connection manner. When the reset block 332 moves, the reset block 332 will slide left and right in the groove inside the installation tube 331. At the same time, the push rod at one end of the push plate 325 extends into the groove inside the installation tube 331. Therefore, when the reset block 332 moves, it will synchronously drive the push plate 325 to achieve displacement.

[0034] A sliding rod 333 is provided on the other external side of the reset block 332 away from the push plate 325. The sliding rod 333 functions to enhance the stability of the reset block 332 during movement. A first spring 334 is provided on the outer side of the sliding rod 333. When the reset block 332 moves left and right in the groove inside the installation tube 331, since the reset block 332 is connected to the sliding rod 333, the sliding rod 333 will synchronously move left and right with the reset block 332. During the movement of the reset block 332, because the first spring 334 is sleeved on the outer wall of the sliding rod 333, during the movement of the reset block, it will exert a squeezing or stretching effect on the first spring 334.

[0035] On the outer wall of the reset block 332, a first positioning groove 335 and a second positioning groove 336 are respectively formed. A reset groove 337 is formed outside the reset block 332 near the second positioning groove 336. Due to the different inclined surface angles of the first positioning groove 335 and the second positioning groove 336, different degrees of tensile displacement distances of the first spring 334 will be generated when the reset block 332 is pressed. It should be noted that the reset groove 337 has a structural form different from the previous two. There is no bayonet structure on one side of the first positioning groove 335 and the second positioning groove 336 on one side. Its inclined structure can not only accurately guide the directional movement of the reset block 332, but also provide accurate and controllable reset assistance.

[0036] During use, during the movement of the reset block 332, the reset block 332 will drive the slide bar 333 to move left and right in the horizontal direction, forcing the first spring 334 to deform and generate a corresponding rebound force. At this time, through the special structural design of different inclined angles of the first positioning groove 335 and the second positioning groove 336, the movement amplitude and positioning accuracy of the reset block 332 are accurately controlled. In particular, the inclined structure of the reset groove 337 effectively assists the reset block 332 to quickly return to its position and maintain a stable state.

[0037] In summary, during the movement of the reset block 332, it moves directionally in the installation pipe 331, and at the same time drives the slide bar 333 to synchronously displace. During the movement of the slide bar 333, it will squeeze or stretch the first spring 334, and use the elastic potential energy of the spring to provide an accurate reset force for the reset block. It is worth noting that the first positioning groove 335 and the second positioning groove 336 are designed with different inclined angles, which not only ensure the accurate positioning of the reset block after movement, but also improve the system stability by accurately controlling the reset stroke. And the reset groove 337 optimizes the return of the reset block 332 through the characteristics of its structure, forming a complete reset assistance feature.

[0038] Example 3, referring to Figure 3 and Figure 4 , which is the third embodiment of the present invention. Different from the previous embodiment, it solves the problem of adjusting the reflector at different angles.

[0039] On one side inside the reset groove 337, there is a transmission member 34 arranged inside the simulation component 30. The transmission member 34 includes a moving groove 341 distributed in a horizontal structure. The transmission member 34 can be used as a core force transmission component. With its exquisitely structured moving groove 341 horizontally distributed on its surface, it not only provides accurate assembly positioning for the transmission rod 342 and the reset rod 343, but also ensures the stable sliding of the transmission rod 342 and the reset rod 343, enhancing the reliability and coordination of the overall structure.

[0040] Inside the moving slot 341, a transfer rod 342 and a return rod 343 are respectively arranged. A second spring 344 is arranged outside the return rod 343 and the transfer rod 342. When the transfer rod 342 is pressed, it realizes smooth sliding by fitting with the moving slot 341. The bayonet design at the end of the transfer rod 342 is like an accurate positioning anchor point, which can accurately lock the position of the return block 332 during the movement process, realizing reliable movement positioning; while the different structure without a bayonet at the end of the return rod 343 makes the two present different effects under the pressing operation. When a force is applied to the return rod 343, it can form a linkage characteristic with the return slot 337.

[0041] On one side of the second spring 344, there is a pressing member 35 arranged outside the simulation component 30. The pressing member 35 includes an installation cover 351. A first pressing rod 352 and a second pressing rod 353 are respectively inserted into the slots inside the installation cover 351. When the first pressing rod 352 and the second pressing rod 353 are pressed, the first pressing rod 352 and the second pressing rod 353 can slide flexibly inside the installation cover 351. The installation cover 351 can prevent dust from invading the inside of the device by fitting with the first pressing rod 352 and the second pressing rod 353, which not only ensures the smooth operation of the pressing rod, but also extends the overall service life and working stability of the device.

[0042] The first pressing rod 352 is arranged at one end of the transfer rod 342, and the second pressing rod 353 is arranged at one end of the return rod 343. When a pressure is applied to the first pressing rod 352, its connection structure with the transfer rod 342 efficiently conducts the pressure, driving the transfer rod 342 to move. When the second pressing rod 353 is pressed, it accurately drives the return rod 343 to displace by virtue of the connection with the return rod 343.

[0043] The support frame 10 includes a bottom plate 111. An elevating frame 112 is arranged outside the bottom plate 111. The elevating frame 112 is located on one side outside the bottom plate 111. The bottom plate 111 can support the device and facilitate the user to move the device by using the universal wheels at the bottom of the bottom plate 111. The elevating frame 112 can realize the lifting operation of the main body 20 and the simulation component 30.

[0044] A connecting frame 113 is arranged on one side of the elevating frame 112. The main body 20 is arranged between the connecting frames 113. The connecting frame 113 can effectively fix the main body 20 between the connecting frames 113 through the connection with the main body 20. Thus, when the connecting frame 113 moves, it will drive the main body 20 to move accordingly.

[0045] In use, the first pressing rod 352 can be pressed according to requirements. The first pressing rod 352 will drive the transmission rod 342 to move. The transmission rod 342 can drive the bayonet at one of its ends to move. During the continuous movement of the bayonet, the inclined structure between the bayonet and the first positioning groove 335 can be utilized to enable the reset block 332 to move to a specified position for reset positioning processing. Moreover, when the transmission rod 342 and the reset rod 343 move, the second spring 344 will also be compressed. When resetting, by pressing the second pressing rod 353, the second pressing rod 353 can drive the reset rod 343 to move. The reset rod 343 can drive the reset block 332 to move by virtue of the fit with the reset groove 337, so that the bayonet on one side of the reset block 332 exits into the bayonet on one side of the transmission rod 342, and the complete reset of the reset block 332 is achieved according to the first spring 334.

[0046] In summary, the second spring 344, the transmission rod 342 and the reset rod 343 are set up to form a linkage structure. When the first pressing rod 352 is pressed, the force can be transmitted to the transmission rod 342. The transmission rod 342 will move and also compress the second spring 344. The bayonet between the bayonet at the end of the transmission rod 342 and the first positioning groove 335 is like a positioning lock, driving the reset block 332 to achieve displacement. The reset structure composed of the second pressing rod 353, the reset rod 343 and the reset groove 337 forms a reliable closed-loop drive during operation to ensure the accurate return of the reset block 332. In addition, the synergistic effect of the second spring 344 further optimizes the return performance of the entire device, significantly improving the integrity and operation stability of the mechanical structure.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
