Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a vehicle headlight optical performance testing device. Background Art

[0002] Traffic safety has been a focus of public attention in recent years. Vehicle headlights are crucial for drivers to obtain road information at night or in low-visibility conditions, and their performance directly impacts driving safety and reliability. Therefore, optical performance testing of vehicle headlights is essential.

[0003] Testing the optical performance of vehicle headlights requires specialized testing equipment. The existing testing method involves inspectors holding the equipment and walking to a pre-set testing location to perform the optical performance test. However, handheld testing equipment can lead to measurement errors, resulting in poor test results. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a vehicle headlight optical performance testing device. By setting a height-adjustable bracket, the measurement height of the illuminance meter can be accurately adjusted. By setting a level, the measurement deviation caused by the tilt of the illuminance meter can be avoided. By setting a laser rangefinder, the height of the starting point and the end point of the measurement can be ensured to be consistent, and the illuminance meter can be aimed at the vehicle headlights, thereby improving the accuracy of the test results.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] In one aspect, an embodiment of the present application provides a vehicle headlight optical performance testing device, comprising:

[0007] A bracket, wherein the height of the bracket is adjustable;

[0008] An illuminance meter, provided on the bracket, for detecting the illuminance of the vehicle headlights;

[0009] A level, provided on the bracket, and used to adjust the horizontal state of the illuminator;

[0010] A laser rangefinder is provided on the bracket to detect the distance between the bracket and the vehicle.

[0011] The vehicle headlight optical performance testing equipment provided in the embodiments of the present application, by providing a height-adjustable bracket, can accurately adjust the illuminance meter to a specified measurement height, thus avoiding deviations caused by manual measurement. At the same time, by providing a level, the level of the illuminance meter can be adjusted during the measurement process, effectively avoiding measurement deviations caused by instrument tilt. Furthermore, by providing a laser rangefinder, the distance between the illuminance meter and the vehicle headlight can be accurately detected. The laser rangefinder can emit a visible beam, facilitating alignment of the illuminance meter with the vehicle headlight, thereby improving the accuracy of the test results. Furthermore, the presence of a level and a laser rangefinder allows measurement personnel to quickly and accurately adjust the angle and position of the vehicle headlight optical performance testing equipment during the illuminance measurement process. Compared to manual measurement, this simplifies the measurement process, significantly improves measurement efficiency, saves time and effort, and provides greater practicality.

[0012] In one possible implementation, the illuminance meter includes:

[0013] a shell, movably connected to the bracket, wherein the position and angle of the shell relative to the bracket are adjustable, and the shell has an inner cavity;

[0014] The illumination detection device is arranged in the inner cavity of the shell.

[0015] In this way, the position and angle of the illumination detection device can be adjusted, so that the illumination detection device can adapt to different measurement environments and requirements.

[0016] In a possible implementation, the level is fixedly disposed on the outside of the shell.

[0017] In this way, the setting of the level meter enables the operator to adjust the horizontal position of the illuminance meter during use, avoiding the horizontal position change of the illuminance meter caused by moving or adjusting the illuminance meter, and ensuring the accuracy of the detection.

[0018] In a possible implementation, a light-transmitting hole is provided on a side wall of the shell, and the laser rangefinder is disposed in an inner cavity of the shell and fixedly connected to the shell.

[0019] In this way, placing the laser rangefinder in the inner cavity of the shell can effectively prevent adverse factors such as dust, moisture, vibration in the external environment from directly affecting the laser rangefinder, thereby extending its service life and improving the stability and accuracy of measurement.

[0020] In one possible implementation, the bracket includes:

[0021] base;

[0022] The telescopic rod comprises at least a first rod body and a second rod body, one end of the first rod body is fixedly connected to the base, the inner side of the first rod body defines an active cavity, an end of the active cavity away from the base is provided with a telescopic opening, the second rod body is telescopically arranged in the active cavity via the telescopic opening, and the illuminator is connected to the second rod body.

[0023] In this way, by providing a telescopic rod, especially a telescopic structure between the first rod body and the second rod body, the bracket can be adjusted in length according to actual needs, thereby enabling the illuminance meter to operate at different measurement heights, thereby enhancing the adaptability of the device.

[0024] In a possible implementation, the bracket further includes: a locking sleeve, which is rotatably disposed at the telescopic opening, and the second rod body is passed through the locking sleeve, and the locking sleeve is used to lock or unlock the second rod body.

[0025] In this way, the locking sleeve serves as a locking device for the second rod. By rotating the locking sleeve to lock the second rod, it effectively prevents the second rod from accidentally sliding or loosening during extension and retraction, thereby ensuring the stability of the stand during use. Furthermore, the provision of the locking sleeve allows the user to quickly lock or unlock the second rod when needed, without the need for additional tools or complicated operations, thus improving operational convenience.

[0026] In a possible implementation, a reference scale line is provided on the second rod.

[0027] In this way, the operator can quickly and accurately determine the telescopic length of the second rod to meet measurement requirements, which helps improve work efficiency.

[0028] In one possible implementation, the bracket includes:

[0029] A pan-tilt device is provided at one end of the second rod body away from the first rod body, the pan-tilt device is rotatable relative to the second rod body, and the illuminator is fixedly connected to the pan-tilt device.

[0030] In this way, the illuminance meter can change its position in the horizontal and vertical directions, so that it can measure at different angles, which helps to obtain more comprehensive measurement data.

[0031] In one possible implementation, the pan / tilt device includes:

[0032] a ball seat, the ball seat being fixed to an end of the second rod body away from the first rod body, the ball seat defining a spherical cavity;

[0033] The ball head rod comprises a rod body and a ball head. The ball head is rotatably fitted in the spherical cavity. One end of the rod body is connected to the ball head, and the other end is connected to the illuminator.

[0034] In this way, the ball head and ball socket form a spherical pair. The ball head can rotate within the spherical cavity of the ball socket, allowing the illuminometer to rotate in any direction and tilt within a certain range. This provides greater freedom of movement and enhances the flexibility of the illuminometer. Furthermore, the ball socket and ball head arrangement is highly strong and stable, capable of supporting the weight of the illuminometer and other equipment, ensuring stability and safety during measurement.

[0035] In one possible implementation, the vehicle headlight optical performance testing device further includes:

[0036] The communication device is suitable for connecting to an external communication device, and is used to obtain control instructions from the external communication device and perform data transmission with the external communication device.

[0054] Testing the optical performance of vehicle headlights requires specialized testing equipment. The conventional testing method involves a technician holding the equipment and walking to a pre-set testing location to perform the optical performance test. However, handheld testing equipment can lead to measurement errors, resulting in poor test results.

[0055] Vehicle headlights, usually referring to vehicle headlights, are lighting devices installed on the front of the car. At night or in low-light environments, vehicle headlights can illuminate the road and the front view, providing drivers with clear lighting needs to ensure driving safety.

[0056] In view of this, an embodiment of the present application provides a vehicle headlight optical performance testing device. By setting a height-adjustable bracket, the measuring height of the illuminance meter can be accurately adjusted to achieve illuminance measurement of the vehicle headlights at different illumination angles. By setting a level meter, it can be ensured that the illuminance meter always remains horizontal during the testing process, effectively avoiding measurement errors caused by angle deviation. By setting a laser rangefinder, it can be ensured that the height of the starting point and end point of the distance measurement are consistent, thereby accurately measuring the distance between the illuminance meter and the vehicle, and enabling the illuminance meter to be aimed at the vehicle headlights, thereby improving the accuracy of the test results.

[0057] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the power type, the car in this application may be a pure electric car, a hybrid car, a fuel car, etc. For a fuel vehicle, the power source may refer to a gasoline engine, a diesel engine or other fuel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power; according to the vehicle model, the car in this application may be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models.

[0058] Reference below Figure 1 The embodiment of the present application provides a vehicle headlight optical performance testing device, including: a bracket 100, an illuminance meter 200, a level meter 300 and a laser rangefinder 400.

[0059] The height of the bracket 100 is adjustable. For example, the bracket 100 can be raised and lowered, extended and retracted, or moved in other forms in the vertical direction to adjust its own height.

[0060] The illuminance meter 200 is provided on the bracket 100 , and is used to detect the illuminance of the vehicle headlights.

[0061] The level 300 may be provided on the bracket 100 and is used to detect the level of the bracket 100, thereby providing a reference for adjusting the level of the illuminance meter 200. For example, the level 300 may be directly fixed to the bracket 100, or may also be fixed to the illuminance meter 200.

[0062] The laser rangefinder 400 is mounted on the bracket 100 to detect the distance between the bracket 100 and the vehicle 10. For example, the laser rangefinder 400 can be directly fixed to the bracket 100, or it can be fixed to the illuminator 200. The relative positions of the illuminator 200, the level 300, and the laser rangefinder 400 can be flexibly adjusted as needed, and this embodiment does not impose any restrictions on this.

[0063] It should be noted that the laser rangefinder 400 can also emit a visible laser beam, which can clearly indicate the measurement direction and target position of the illuminometer 200, helping the operator to quickly and accurately locate the point to be measured.

[0064] For example, there may be multiple points to be tested. Specifically, there may be five points to be tested. The locations and distribution of the points to be tested may be determined based on actual application scenarios and requirements.

[0065] In one possible design, reference Figure 2 and Figure 3 When determining the location of the test point, the vehicle's position can be used as the center point, and a normal line 20 is formed based on the vehicle's position. Normal line 20 extends from the vehicle's position toward the vehicle headlight optical performance testing equipment. Based on the vehicle's headlight lighting characteristics and testing requirements, two test points are selected on normal line 20. These two points can be located at different distances within the headlight's illumination range, for example, one point in the low-beam illumination area and the other in the high-beam illumination area. The distances from these two points to the vehicle's position are recorded for subsequent analysis. Furthermore, a normal line segment is formed on normal line 20 based on the two test points. This normal line segment includes the two test points. This normal line segment will be used for subsequent horizontal line division and test point selection. Furthermore, two horizontal lines perpendicular to normal line 20 are drawn between the starting and end points of the normal line segment, dividing the normal line segment into three equal parts. This results in three equal-length horizontal line segments that intersect the normal line segment at three equal points. Finally, a test point is selected on each horizontal line segment. These test points are located on both sides of the intersection of the horizontal straight line segment and the normal segment, and are at different distances from the normal segment. This ensures that the test points cover different areas of the headlight illumination range.

[0066] In another possible design, when determining the location of the test point, the vehicle's position can be used as the center point, and a normal line 20 can be formed based on the vehicle's position. Normal line 20 extends from the vehicle's position toward the vehicle headlight optical performance testing equipment. Four horizontal lines perpendicular to normal line 20 are drawn on normal line 20, each of which intersects normal line 20. Furthermore, the distance between each horizontal line can be the same or different, and can be determined based on actual needs, which is not limited in this embodiment. Furthermore, three horizontal lines are selected from the four horizontal lines, and a test point is selected on each of these three horizontal lines, with each test point on each horizontal line maintaining a certain distance difference from normal line 20. The test points on these three horizontal lines are recorded. Furthermore, a test point is selected between the intersection of the horizontal lines containing the three test points and normal line 20, with the test point located on normal line 20. Furthermore, a test point is selected outside the intersection of the horizontal line where the three test points are located and the normal line 20, and the test point is located on the normal line 20. The two test points on the normal line 20 are kept at a certain distance difference from the vehicle 10. This method can more efficiently determine the position of the test point, and accurately measure and record it, thereby improving detection efficiency.

[0067] It should be noted that when determining the positions of the test points, the laser rangefinder 400 can be used to measure and record the distance between each test point and the vehicle position, as well as the distance between each test point and the normal 20. In actual operation, the positions of the test points can be clearly marked with a marker. For example, the marker can be a tape or a sticker.

[0068] After determining the locations of all test points, the operator can use the vehicle headlight optical performance testing equipment to test each of the test points one by one according to the above test points. The operator can also use multiple vehicle headlight optical performance testing equipment to test the optical performance of the vehicle headlights at different test points simultaneously, thus achieving multi-point measurement.

[0069] The vehicle headlight optical performance testing equipment provided in the embodiment of the present application, by providing a height-adjustable bracket 100, can accurately adjust the measuring height of the illuminance meter 200 to realize illuminance measurement of the vehicle headlights at different illumination angles. By providing a spirit level 300, it can be ensured that the illuminance meter 200 always remains in a horizontal state during the testing process, effectively avoiding measurement errors caused by angle deviation. By providing a laser rangefinder 400, it can be ensured that the heights of the starting point and the end point of the distance measurement are consistent, thereby accurately measuring the distance between the illuminance meter 200 and the vehicle 10, and enabling the illuminance meter 200 to be aligned with the vehicle headlights, thereby improving the accuracy of the test results. In addition, since it is equipped with a spirit level 300 and a laser rangefinder 400, the measurement personnel can quickly and accurately adjust the angle and position of the vehicle headlight optical performance testing equipment during the illuminance measurement process. Compared with manual measurement, the measurement steps can be simplified, the measurement efficiency can be greatly improved, time and effort can be saved, and the practicality is better.

[0070] In some embodiments of the present application, the illuminance meter 200 includes: a shell 210 and an illuminance detection device 220. The shell 210 can be a square shell, a spherical shell, an elliptical shell or a shell of any other shape, and the shell 210 can provide installation space and external protection for the illuminance detection device 220. The shell 210 can be movably connected to the bracket 100, and the position and angle of the shell 210 relative to the bracket 100 are adjustable. The shell 210 has an inner cavity; the illuminance detection device 220 is a functional component in the illuminance meter 200 for measuring the illumination intensity of the vehicle headlights, and the illuminance detection device 220 is arranged in the inner cavity of the shell 210. Optionally, a light hole can be opened on the shell 210, and a light shield is provided at the light hole, and the illuminance detection device 220 is arranged opposite to the light hole.

[0071] It can be understood that the shell 210 and the bracket 100 are movably connected, allowing the operator to adjust the position and observation angle of the shell 210 according to actual needs, thereby ensuring that the illumination detection device 220 can be accurately aligned with the area to be tested (vehicle headlights) to obtain accurate illumination data.

[0072] In one possible design, the inner cavity of the housing 210 provides a stable and protected working environment for the illumination detection device 220. The inner cavity can be equipped with shock-absorbing materials or structures to effectively reduce the impact of external vibrations on detection accuracy.

[0073] In this way, the position and angle of the illuminance detection device 220 can be adjusted, so that the illuminance detection device 220 can adapt to different measurement environments and requirements, thereby enhancing the adaptability and practicality of the illuminance meter 200 in different application scenarios.

[0074] In some embodiments of the present application, the level 300 is fixedly disposed on the outside of the housing 210 .

[0075] It is understood that the level 300 can be located at the top of the housing 210. Alternatively, the level 300 can be located at the bottom of the housing 210. Alternatively, the level 300 can be located on either side of the housing 210. When the level 300 is located at the top of the housing 210, the operator can easily view the level from above without having to bend or lower their head. When the level 300 is located at the bottom of the housing 210, it is more convenient for observation when measuring in low spaces or on the ground. The left and right side settings provide the operator with more options and can be adjusted according to the actual measurement environment and personal preferences.

[0076] In this way, the setting of the level 300 enables the operator to adjust the horizontal position of the illuminance meter 200 during use, avoiding the horizontal position change of the illuminance meter 200 that may be caused by moving or adjusting the illuminance meter 200, and ensuring the accuracy of detection.

[0077] Optionally, the level 300 can be fixed to the housing 210 of the illuminator 200 by bonding, snapping, screwing or any other connection method to ensure the installation stability and convenience of the level 300.

[0078] In some embodiments of the present application, a light-transmitting hole is provided on the side wall of the shell 210 , and the laser rangefinder 400 is disposed in the inner cavity of the shell 210 and is fixedly connected to the shell 210 .

[0079] It can be understood that the light-transmitting hole is closely connected to the laser rangefinder 400 in the housing 210 . The laser rangefinder 400 is fixedly arranged in the housing 210 , and the laser beam it emits is emitted outward through the light-transmitting hole to measure the distance between the illuminance meter 200 and the vehicle 10 .

[0080] The position, size, and shape of the aperture can be determined based on actual needs to ensure unimpeded laser beam transmission while effectively preventing interference from external light, ensuring measurement accuracy. The aperture can also be equipped with a lens or filter to further optimize the transmission characteristics of the laser beam, improving the accuracy and stability of ranging.

[0081] In this way, placing the laser rangefinder 400 in the inner cavity of the housing 210 can effectively prevent adverse factors such as dust, moisture, and vibration in the external environment from directly affecting the laser rangefinder 400, thereby extending its service life and improving measurement stability and accuracy.

[0082] In some embodiments of the present application, the bracket 100 may include: a base 110 and a telescopic rod 120. The base 110 may be square, circular, triangular, or any other shape. The telescopic rod 120 may include at least: a first rod 121 and a second rod 122. One end of the first rod 121 is fixedly connected to the base 110, for example, by welding. The inner side of the first rod 121 defines an active cavity. The end of the active cavity away from the base 110 is provided with a telescopic opening. The second rod 122 is telescopically arranged in the active cavity via the telescopic opening. The illuminator 200 is connected to the second rod 122.

[0083] It is understandable that the illuminance meter 200 can achieve vertical height adjustment through the telescopic rod 120. The setting of the telescopic opening allows the second rod body 122 to telescope in the movable cavity, which not only ensures the stability of the structure but also provides sufficient flexibility to adapt to different detection scenarios.

[0084] In one possible design, the base 110 may also be provided with rollers. The rollers are located at the bottom of the base, and the rollers enable the bracket 100 to easily move the illuminance meter 200 within the detection area, allowing the operator to quickly adjust the position of the illuminance meter 200, thereby improving detection efficiency.

[0085] In one possible design, the stand 100 can also be a tripod structure. The stand 100 consists of three support legs arranged in an equilateral triangle or a near-equilateral triangle configuration, forming a stable support base. Furthermore, each leg is designed with adjustable length, allowing the user to independently adjust the length of each leg based on floor flatness or measurement requirements, ensuring that the stand 100 remains level. This adjustment mechanism can be implemented using a screw lock or telescopic segments.

[0086] In this way, by setting the telescopic rod 120, especially the telescopic structure between the first rod body 121 and the second rod body 122, the bracket 100 can adjust the length according to actual needs, thereby enabling the illuminance meter 200 to operate at different measurement heights, thereby enhancing the adaptability of the equipment.

[0087] In some embodiments of the present application, the bracket 100 further includes: a locking sleeve 130 rotatably disposed at the telescopic opening, the second rod 122 passing through the locking sleeve 130 , and the locking sleeve 130 is used to lock or unlock the second rod 122 .

[0088] Thus, the locking sleeve 130 serves as a locking device for the second rod 122. By rotating the locking sleeve 130 to lock the second rod 122, it is possible to effectively prevent the second rod 122 from accidentally sliding or loosening during the extension and retraction process, thereby ensuring the stability of the stand 100 during use. Furthermore, the provision of the locking sleeve 130 allows the user to quickly lock or unlock the second rod 122 when needed, without the need for additional tools or complicated operations, thus improving operational convenience.

[0089] In some embodiments of the present application, a reference scale line is provided on the second rod 122 .

[0090] Exemplarily, the reference scale line has a preset range, for example, from 18 cm to 30 cm.

[0091] In this way, the operator can quickly and accurately determine the telescopic length of the second rod 122 to meet measurement requirements, thereby improving work efficiency.

[0092] In some embodiments of the present application, the bracket 100 includes: a pan-tilt device 140, which is arranged at the end of the second rod 122 away from the first rod 121, and the pan-tilt device 140 is rotatable relative to the second rod 122, and the illuminance meter 200 is fixedly connected to the pan-tilt device 140.

[0093] In this way, the illuminance meter 200 can change its position in the horizontal and vertical directions, so that it can perform measurements at different angles, which helps to obtain more comprehensive measurement data.

[0094] In some embodiments of the present application, the pan-tilt device 140 includes: a ball seat 141, which is fixed to the end of the second rod body 122 away from the first rod body 121, and the ball seat 141 defines a spherical cavity; a ball head rod 142, which includes a rod body 1421 and a ball head 1422, and the ball head 1422 can be rotatably engaged in the spherical cavity, one end of the rod body 1421 is connected to the ball head 1422, and the other end is connected to the illuminance meter 200.

[0095] Thus, ball head 1422 and ball socket 141 form a spherical pair. Ball head 1422 can rotate within the spherical cavity of ball socket 141, allowing illuminometer 200 to rotate in any direction and tilt within a certain range, providing greater freedom of movement and enhancing the flexibility of illuminometer 200. Furthermore, the arrangement of ball socket 141 and ball head 1422 offers high strength and stability, capable of supporting the weight of illuminometer 200 and other equipment, ensuring stability and safety during measurement.

[0096] In some embodiments of the present application, the vehicle headlight optical performance testing device further includes: a communication device, which is suitable for connecting to an external communication device, for obtaining control instructions from the external communication device, and for transmitting data with the external communication device.

[0097] It is understandable that the data transmitted between the communication device and the external communication equipment can be the light intensity data detected by the illuminance meter 200, the distance data detected by the laser rangefinder 400, etc. The communication device has a variety of data transmission methods such as wired, wireless (such as Wi-Fi, Bluetooth, NFC, etc.) and manual reading, ensuring a stable connection with external communication equipment (such as smart phones, tablets, professional detection terminals, etc.) under different environments and needs. The operator can choose to send the light intensity data directly to the external communication device through the communication device, and realize remote monitoring and management of the data by viewing, analyzing and storing it on the external communication device. Similarly, distance data also supports wireless transmission to the external communication device. The operator can view detailed reports on the external communication device, including distance, measurement time, etc., to facilitate subsequent analysis and report generation.

[0098] In one possible design, the vehicle headlight optical performance testing equipment is equipped with a display screen. This screen can directly display the currently detected light intensity value, facilitating on-site instantaneous viewing. Similarly, the display screen on the vehicle headlight optical performance testing equipment can also display real-time ranging results, facilitating on-site operation.

[0099] In this way, by connecting the communication device to an external communication device, remote control of the vehicle headlight optical performance testing equipment can be achieved, and the testing equipment can be started, stopped or adjusted without the operator having to operate it personally, thereby improving the testing efficiency.
