Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a component for detecting the light-transmitting surface area of ​​automotive taillights. Background Technology

[0002] As a key component of vehicle safety, the optical performance of automotive taillights, especially their light transmission capacity and light source intensity, plays a decisive role in driving safety. The light transmission area, as the core indicator for measuring the light transmission performance of taillights, directly affects the uniformity and brightness of light distribution. Insufficient light source intensity will make it difficult for signals to be clearly identified in complex environments (such as foggy weather, strong light, or nighttime), failing to effectively warn vehicles behind, thus significantly increasing the risk of rear-end collisions. Therefore, ensuring that taillights have excellent light transmission area and sufficient light source intensity is an indispensable technical element for ensuring road traffic safety.

[0003] In existing technologies, detection techniques for these two key indicators generally suffer from low efficiency, high cost, and limited accuracy. In terms of light transmittance detection, mainstream methods rely on complex and expensive professional optical instruments, or time-consuming and labor-intensive manual measurement methods that are susceptible to subjective factors. These methods are not only cumbersome and inefficient, but also fail to fully guarantee the repeatability and accuracy of the results. Furthermore, the detection of light source intensity often requires the introduction of additional specialized testing equipment, which further increases the overall detection cost, adds to the complexity of operation, and slows down the detection efficiency. Therefore, we urgently need a light transmittance detection component for automotive taillights to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high cost, complex operation, and low efficiency in the detection of the light-transmitting surface area and light source intensity of automobile taillights in the prior art, and to propose an automobile taillight light-transmitting surface area detection component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A component for detecting the light transmittance area of ​​an automotive taillight includes a substrate. A central hole is formed in the middle of the substrate. Four arc-shaped through holes are formed on the substrate and on the outer side of the central hole. A light cover for detecting the intensity of the light source is installed on the central hole and the arc-shaped through holes.

[0007] In order to inspect the light source of the taillight, preferably, the four arc-shaped through holes are symmetrically distributed around the center of the central hole, and the two ends of a single arc-shaped through hole form a 60° central angle with the center of the central hole.

[0008] To avoid blocking the light source, the inner diameter of the arc-shaped through hole is 80mm, and the width of the arc-shaped through hole ranges from 15mm to 20mm.

[0009] To accommodate taillights of different shapes, the diameter of the central hole is preferably 40mm.

[0010] To avoid stray light interference, the substrate is preferably made of black ABS plastic.

[0011] To ensure uniform light diffusion, the light cover is preferably made of acrylic with a light transmittance range of 90%-92%.

[0012] For ease of use, preferably, a handle is fixedly connected to the side of the substrate.

[0013] To quickly determine whether the light source intensity meets the requirements, preferably, a brightness gradient indicator is fixedly connected to the substrate.

[0014] Compared with the prior art, this utility model provides a component for detecting the light-transmitting surface area of ​​automotive taillights, which has the following beneficial effects:

[0015] 1. This automotive taillight light-transmitting surface area detection component, through the design of a substrate, a central hole, and an arc-shaped through-hole, makes the through-hole the only area through which light can pass, thus clearly defining the detection benchmark and solving the problem of meaningless through-holes under a transparent substrate. It can accurately detect the light-transmitting surface area and simultaneously detect the light source intensity. It has fewer parts, a simple structure, is easy to manufacture and produce, has low cost, and is easy to operate. When using it, simply place the component on the light-transmitting surface of the automotive taillight and turn on the taillight to simultaneously detect the light-transmitting surface area and the light source intensity. The operation steps are simple, making it easy to quickly apply on the production line and improve detection efficiency.

[0016] 2. This automotive taillight light-transmitting surface area detection component, through the setting of the photomask, the light-shielding effect of the opaque substrate, the setting of the through holes, and the function of the photomask, can accurately reflect the light-transmitting surface area and light source intensity of the automotive taillight. The detection results are reliable. The photomask is made of semi-transparent diffuse reflection material and has brightness gradient markings, which are convenient for observation and judgment.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has reasonable functions, simple structure, and convenient operation, making it easy to apply quickly on the production line, improving detection efficiency. It can also simultaneously detect the light transmission and light intensity of the taillight, thus improving the stability of the detection. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0026] Reference Figures 1-5 A component for detecting the light-transmitting surface area of ​​an automotive taillight includes a base plate 1. A handle 5 is fixedly connected to the side of the base plate 1, and a brightness gradient indicator 6 is fixedly connected to the base plate 1. The base plate 1 is made of black ABS plastic and is rectangular in shape. The handle 5 is covered with a friction pad for anti-slip. The brightness gradient indicator 6 can serve as a visual reference standard. By comparing the brightness of the light cover 4 after receiving light with the indicator, it is possible to quickly determine whether the light source intensity meets the requirements. If the brightness of the light cover 4 reaches the corresponding standard gradient indicator, the light source intensity is qualified; if it does not reach the standard, the light source intensity is insufficient.

[0027] It should be noted that black ABS plastic material has good light-blocking properties, which can effectively prevent stray light interference and ensure that only the through-hole area can transmit light. In addition, it has the characteristics of high material strength, wear resistance and long service life.

[0028] A central hole 2 is provided in the middle of the substrate 1. The diameter of the central hole 2 is 40mm. Four arc-shaped through holes 3 are provided on the substrate 1 and on the outer side of the central hole 2. The four arc-shaped through holes 3 are symmetrically distributed with respect to the center of the central hole 2. The two ends of each arc-shaped through hole 3 form a 60° central angle with the center of the central hole 2. The inner diameter of the arc-shaped through hole 3 is 80mm, and the width of the arc-shaped through hole 3 is between 15mm and 20mm.

[0029] Here, the size of the central hole 2 is 40mm. When the taillight is not round, the light-emitting surface area of ​​the taillight must be at least equivalent to the area of ​​a circle with a diameter of 80mm. Moreover, the narrowest part of its shape must be able to fit a circle with a diameter of 40mm. When the light-emitting surface of the taillight is round, the diameter of the circle must be at least 80mm.

[0030] It should be noted that the total coverage of the four arc-shaped through holes 3 on the substrate 1 reaches 240°, and this distribution method can make the detection more comprehensive and uniform, improve the accuracy of the detection, and ensure that irregular lampshades such as trapezoids and irregular shapes can meet the minimum area requirements in any direction. The width of the arc-shaped through holes 3 is preferably 17mm. Within this width range, sufficient light can be passed through, which is convenient for observation and detection, while avoiding the through holes being too wide and affecting the structural strength of the substrate 1.

[0031] Both the central hole 2 and the arc-shaped through hole 3 are equipped with a light cover 4 to reflect the intensity of the light source. The material of the light cover 4 is acrylic, and its light transmittance ranges from 90% to 92%, with 92% being preferred. This light transmittance ensures that enough light passes through the light cover 4 so that the inspectors can clearly observe the light conditions, while avoiding discomfort to the human eye and interference with observation and judgment caused by direct strong light through diffuse reflection, thereby more clearly displaying the distribution of the light source intensity.

[0032] Here, the photomask 4 is either circular or arc-shaped, respectively adapting to the shape of the central hole 2 and the arc-shaped through hole 3. The acrylic photomask 4 can diffuse the light evenly, avoiding strong direct light from affecting observation, and can more clearly display the distribution of the light source intensity. In addition, the photomask 4 is detachable, so it can be easily replaced when the photomask 4 is worn or contaminated, which affects observation, ensuring the accuracy of the detection.

[0033] It should be noted that adding a light cover 4 to the central hole 2 can both supplement the intensity of the taillight's light source and avoid strong light interference, making the component's detection function more complete and the operation more consistent.

[0034] In this invention, when in use, the detection component is placed on the light-transmitting surface of the car taillight to be detected, so that the light-emitting center of the car taillight corresponds to the central hole 2 of the substrate 1. Then the car taillight is turned on. Since the substrate 1 is opaque, the light can only shine onto the photomask 4 through the central hole 2 and the arc-shaped through hole 3.

[0035] For the detection of the light-transmitting surface area, by observing the coverage of light on the area corresponding to the arc-shaped through-hole 3 on the photomask 4, and combining it with the pre-set area parameters of the arc-shaped through-hole 3, it is possible to quickly determine whether the light-transmitting surface area of ​​the car taillight meets the standard. If the area covered by the light is completely consistent with the area of ​​the photomask 4 corresponding to the arc-shaped through-hole 3, it means that the light-transmitting surface area of ​​the car taillight meets the standard; if there are some areas without light coverage, it means that the light-transmitting surface area of ​​that part is insufficient and does not meet the standard.

[0036] For light source intensity testing, after the light is diffused by the photomask 4, the light source intensity can be intuitively judged based on the brightness of the photomask 4 and the comparison with the brightness gradient mark 6 on the substrate 1. If the brightness of the photomask 4 reaches the corresponding standard gradient mark, the light source intensity is qualified; if it does not reach the standard, the light source intensity is insufficient.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
