Description

Technical Field

[0001] This utility model relates to the technical field of reflectivity testing equipment, specifically a reflectivity testing device for automotive display screen glass panels. Background Technology

[0002] The reflectivity test for automotive display screen glass panels aims to evaluate their readability in bright light conditions. Reflected light brightness is measured at specific incident and viewing angles using an imaging luminance meter, ensuring a contrast ratio of at least 2:1. The test simulates direct sunlight conditions, with the light source's field of view matching the sun's field of view. Furthermore, optical simulation software can be used to simulate the cabin environment and analyze the impact of screen reflections on the driver's vision. The test also includes parameters such as gloss and haze to quantify the anti-glare effect. These tests allow for the optimization of anti-glare treatment for display screen glass panels, improving driving safety.

[0003] Utility model CN208313828U discloses a reflectivity detection device for vehicle-mounted electronic displays. The device includes a main body with a movable opaque cover movably mounted on its top. A mounting bracket is fixedly installed on the left side of the top of the main body, inside the opaque cover. A laser lamp body is fixedly installed on the left side of the top wall of the opaque cover. A square groove is formed on the right side of the top of the opaque cover, and locking blocks are fixedly installed on the side walls of the groove. A light-sensing element is fixedly installed in the groove via the locking blocks. This reflectivity detection device for vehicle-mounted electronic displays uses the contraction and rebound of springs to move the movable block within the mounting groove, thereby driving the movable bracket to move left and right. Displays of different sizes can be clamped between the clamping grooves, allowing for the detection of displays of different sizes, achieving a convenient and easy-to-use effect, and improving the convenience of the reflectivity detection device.

[0004] While the aforementioned testing device can clamp and fix displays of different sizes, when applied to clamping and fixing display glass panels, the glass panels are typically thin and large, making them prone to bending and deformation under pressure, affecting the accuracy of the test results. They can even easily bend and break under significant clamping force. Furthermore, the positions of the object under test, the laser, and the photosensitive element in the aforementioned testing device cannot be adjusted, thus only allowing testing of a specific point on the object, preventing a comprehensive test and affecting the completeness of the test results. Therefore, to address these issues, a reflectivity testing device for automotive display glass panels is proposed. Utility Model Content

[0005] To address the technical problems of the clamping and fixing method of reflectivity testing equipment in comparative technology, which easily causes the object under test to bend, deform, or even break, and the fact that it can only test a specific point of the object under test, this utility model provides a reflectivity testing device for automotive display screen glass panels.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A reflectivity testing device for automotive display screen glass panels includes a base with a light shield mounted on it, and a rotating door rotatably connected to the light shield; a screw drive rail seat mounted on the base, on which a sliding stage is mounted, the screw drive rail seat driving the sliding stage to reciprocate; and a reflectivity testing mechanism mounted on the light shield, including a laser lamp and a photosensitive element that works in conjunction with it; wherein, the sliding stage includes a carrier plate with mounting holes arranged in a circumferential array, and a plurality of panel support members are mounted in the mounting holes, each panel support member including a mounting shaft seat with a suction cup mounted at its top, a sliding support cylinder slidably mounted on its outer side, and a support spring at the bottom of the sliding support cylinder.

[0008] In one possible implementation, the mounting bearing includes a limiting piece, the lower end face of which is fixedly provided with a threaded head for threaded connection with the mounting hole, and the upper end face of which is fixedly provided with a shaft.

[0009] In one possible implementation, the sliding support cylinder includes a sliding cylinder slidably connected to the shaft, with a support plate fixedly connected to its top end, and the support spring sleeved outside the shaft and located between the sliding cylinder and the limiting plate.

[0010] In one possible implementation, when the sliding cylinder is not subjected to external force and the support spring is at its initial length, the plane containing the upper end face of the support plate is higher than the plane containing the lower end face of the suction cup.

[0011] In one possible implementation, the shaft has grooves on both sides, and the inner wall of the sliding cylinder is fixedly provided with a retaining rib that is slidably disposed in the groove.

[0012] In one possible implementation, the lead screw drive rail base includes two symmetrically arranged guide rails, and the bottom of the carrier plate is provided with a plurality of symmetrically arranged rollers that roll along the guide rails; the lead screw drive rail base also includes a drive lead screw rotatably mounted on the base, and a transmission table mounted on the bottom of the carrier plate, and a drive motor for driving the drive lead screw to rotate is mounted on the base, wherein the drive lead screw passes through the transmission table and is threadedly connected to it.

[0013] In one possible implementation, the guide rail has a Y-shaped cross-section and a guide groove on its upper end face. The roller component includes a folded plate seat on which a roller body that fits into the guide groove is mounted.

[0014] In one possible implementation, two symmetrically arranged positioning baffles are fixedly provided at the front end of the carrier plate.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] Because the mounting holes are arranged in a circular array on the carrier plate, the operator can select the appropriate position to install the corresponding number of panel supports according to the size of the panel to be tested, so as to adapt to the fixing work of panels of different sizes. When installing the panel, it is first placed on the sliding support cylinder. At this time, the position of the panel can be easily adjusted to make it align. Then, the panel is pressed down so that the sliding support cylinder overcomes the thrust of the support spring and slides down, allowing the suction cup to contact the panel to be tested and adhere and fix it. This fixing method is easy to operate and can provide multi-point support for the panel, preventing the panel from deforming or being damaged during the fixing process.

[0017] Furthermore, since the sliding platform is mounted on the lead screw drive rail, when performing reflective testing on the panel, the drive motor in the lead screw drive rail can drive the lead screw to rotate, which in turn drives the transmission platform connected to it to slide the platform back and forth along the guide rail, so that the panel mounted on it can completely pass through the detection points of the laser light, thereby completing the comprehensive testing of the panel.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 2 As shown, this embodiment provides a car display glass panel reflectivity testing device, including a base 1, on which a light shield 11 is provided, and a rotating door 12 rotatably connected to the light shield 11 is installed; a screw drive rail 2 is provided on the base 1, on which a sliding platform 3 is installed, and the screw drive rail 2 is used to drive the sliding platform 3 to reciprocate; a reflectivity testing mechanism 5 is installed on the light shield 11, including a laser lamp 51 and a photosensitive element 52 that works with it; wherein, the sliding platform 3 includes a carrier plate 31, on which mounting holes 32 arranged in a circumferential array are opened, and a plurality of panel support members 4 are installed in the mounting holes 32.

[0028] Based on the above technical solution, the panel to be tested is fixedly installed by the panel support 4. During the test, the lead screw drives the sliding platform 3 to slide and pass under the laser lamp 51 at an angle, thereby ensuring that the laser lamp 51 can reflect light on the entire panel to be tested and ensure the comprehensiveness of the test effect. In addition, the light shield 11 can separate the test environment from the external environment and avoid the external ambient light from affecting the test results.

[0029] The panel support 4 includes a mounting shaft 41 with a suction cup 42 mounted on its top. A sliding support cylinder 43 is slidably mounted on its outer side, and a support spring 44 is provided at the bottom of the sliding support cylinder 43. In addition, two symmetrically arranged positioning baffles 33 are fixedly provided at the front end of the carrier plate 31. Figure 3 - Figure 4 As shown.

[0030] The mounting bearing 41 includes a limiting piece 411, with a threaded head 412 fixedly disposed on its lower end face for threaded connection with the mounting hole 32, and a shaft 413 fixedly disposed on its upper end face. The sliding support cylinder 43 includes a sliding cylinder 431 slidably connected to the shaft 413, with a support plate 432 fixedly connected to its top end. A support spring 44 is sleeved on the shaft 413 and located between the sliding cylinder 431 and the limiting piece 411. If the suction cup 42 is used directly to adsorb and fix the panel during installation, it will be difficult to adjust the position of the panel during installation to align it with the positioning baffle 33. To ensure the placement position does not shift, since the panel will be subject to a certain degree of adhesion after contacting the suction cup 42, making adjustment difficult, a sliding support cylinder 43 is used to initially support the panel during installation. This allows the operator to slide the panel to adjust its position. After the position is adjusted, the panel is pressed down, causing the sliding support cylinder 43 to slide down against the thrust of the support spring 44, allowing the suction cup 42 to contact and adhere to the panel to be tested. This fixing method is easy to operate and can provide multi-point support for the panel, preventing deformation or damage to the panel during the fixing process.

[0031] To ensure that the sliding support cylinder 43 can effectively support the panel in the initial stage, the following conditions must be met: when the sliding cylinder 431 is not subjected to external force and the support spring 44 is at its initial length, the plane containing the upper end face of the support plate 432 is higher than the plane containing the lower end face of the suction cup 42. At this time, the support plate 432 is higher than the suction cup 42, which can provide initial support for the panel, so that the panel does not contact the suction cup 42 in the initial placement stage, making it easy to adjust its position. Figure 4 As shown.

[0032] Furthermore, to prevent the sliding cylinder 431 from deflecting during its up-and-down sliding process and affecting its use, grooves 414 are provided on both sides of the shaft 413, and a retaining rib 433 is fixedly provided on the inner wall of the sliding cylinder 431 and slidably disposed in the groove 414, such as... Figure 4 As shown.

[0033] like Figure 5 - Figure 6 As shown, the lead screw drive rail base 2 includes two symmetrically arranged guide rails 21, and a number of symmetrically arranged rollers 34 are provided at the bottom of the carrier plate 31. The rollers 34 roll along the guide rails 21. The lead screw drive rail base 2 also includes a drive lead screw 22 rotatably mounted on the base 1, and a transmission table 24 mounted on the bottom of the carrier plate 31. A drive motor 23 for driving the drive lead screw 22 to rotate is mounted on the base 1. The drive lead screw 22 passes through the transmission table 24 and is threadedly connected to it.

[0034] Based on the above technical solution, since the sliding platform 3 is installed on the lead screw drive rail 2, when the reflectivity of the panel is detected, the drive motor 23 in the lead screw drive rail 2 can drive the drive lead screw 22 to rotate, thereby driving the transmission platform 24 connected to it to drive the carrier plate 31 to slide back and forth along the guide rail 21, so that the panel installed on it can completely pass through the detection point of the laser lamp 51, thereby completing the comprehensive detection of the panel.

[0035] The guide rail 21 has a Y-shaped cross-section and a guide groove on its upper end face. The roller component 34 includes a folded plate seat 341, on which a roller body 342 that fits with the guide groove is installed. Based on the above technical solution, the sliding connection between the carrier plate 31 and the guide rail 21 can be realized, which makes it easy for the drive motor 23 to drive the carrier plate 31 to move back and forth through the drive screw 22.

[0036] The working principle and usage process of this utility model:

[0037] Before testing, open the rotating door 12 and place the panel to be tested on the panel support 4 of the sliding platform 3. At this time, the sliding support cylinder 43 provides initial support for the panel, making it convenient for the operator to slide the panel to adjust its position, so that the front end of the panel is aligned with the positioning baffle 33 to ensure that the placement position does not shift.

[0038] After the position adjustment is completed, pressing down the panel causes the sliding support cylinder 43 to slide down against the thrust of the support spring 44, allowing the suction cup 42 to contact and adhere to the panel to be tested. This fixing method is easy to operate and can provide multi-point support for the panel, preventing the panel from deforming or being damaged during the fixing process.

[0039] During testing, the rotating door 12 is closed, and the laser lamp 51 emits detection light to illuminate the panel to be tested. The photosensitive element 52 is used to receive the reflected light to calculate its reflectivity. At the same time, the drive motor 23 in the lead screw drive rail 2 drives the drive lead screw 22 to rotate, which in turn drives the transmission table 24 connected to it to drive the carrier plate 31 to slide back and forth along the guide rail 21, so that the panel installed on it can completely pass through the detection point of the laser lamp 51, thereby completing the comprehensive testing of the panel.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
