Description

Technical Field

[0001] This utility model relates to the field of road marking measurement light source technology, and in particular to a configurable light source for road marking measurement equipment. Background Technology

[0002] The light source of the road marking measurement equipment is mainly used to simulate the illumination conditions of vehicle headlights during nighttime driving in order to accurately detect the retroreflective performance of the markings. It adopts a CIE A light source, whose spectral characteristics are close to those of car headlights, ensuring that the measurement results are consistent with the visual effect during actual nighttime driving. The light source of the road marking measurement equipment is located inside the detection equipment.

[0003] In existing technologies, traditional light sources and detection equipment are highly integrated, requiring complete disassembly for repair or upgrades, resulting in high costs. The light source parameters are fixed, making them unsuitable for different marking materials. Furthermore, the use of bolts to fix the light source makes disassembly and assembly time-consuming. In addition, traditional light sources adjust brightness via software, and the hardware cannot be quickly replaced to adapt to different scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a configurable light source for a road marking measurement device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a configurable light source for a road marking measurement device, comprising a road marking measurement body, wherein a light source body is fixed at one end of the road marking measurement body, and the light source body is fixed to one end of the road marking measurement body by magnetic attraction; the inner wall of the light source body is provided with a lamp plate, a frame and a light-transmitting plate, and the light-transmitting plate, the frame and the lamp plate are sequentially passed through by lamp plate screws and threadedly fixed to the inner wall of the light source body.

[0006] Preferably, the road marking measuring body is fixed to the inner wall of the light source body via a fixing screw hole. A magnetic connector female is fixed to one end of the connecting base near the light source body. A guide hole is provided at one end of the connecting base. Multiple guide holes are provided at one end of the road marking measuring body near the light source body. A magnetic connector male is provided at one end of the light source body near the road marking measuring body. A guide shaft is fixed to one end of the connecting base.

[0007] Preferably, an internal bearing is fixed to the inner wall of the guide hole.

[0008] Preferably, one end of the light source body near the road marking measuring body is fixed with multiple hollow magnets by magnetic screws, and multiple base magnets are fixed at the corresponding positions of the connecting base and the hollow magnets.

[0009] Preferably, the bottom of the light source body is fixed with a ground support foot.

[0010] Preferably, the bottom of the ground support foot is covered with a rubber layer.

[0011] Preferably, the thickness of the road marking measuring body at the location corresponding to the base magnet and the hollow magnet is less than the thickness at other locations of the road marking measuring body.

[0012] Beneficial effects:

[0013] 1. This utility model achieves the connection and fixation of the road marking measurement body and the light source body through magnetic attraction, enabling quick assembly and disassembly of the light source body. It allows for rapid replacement of the light source for different detection scenarios. When the light source module is upgraded individually, there is no need to replace the entire detection equipment, reducing user costs. At the same time, this method adjusts the light source model and brightness parameters by replacing hardware, eliminating the need for staff to make adjustments through software. This reduces the experience and training required for staff, allowing them to perform the assembly, disassembly, and replacement of the light source with minimal training. The usage threshold is greatly lowered, reducing the training costs for enterprises.

[0014] 2. This utility model achieves the corresponding adsorption between the hollow magnet and the magnetic screw, so that the road marking measuring body and the light source body are fixed by magnetic force. This helps to eliminate the tiny gaps between the two, increases the fixing effect, facilitates disassembly and assembly, and at the same time eliminates the small gaps so that dust cannot enter the connection between the two, preventing poor contact caused by dust entering the connection port and ensuring the stability of the equipment.

[0015] 3. This utility model enables the operator to prevent the light source body from directly colliding with the ground during use due to slippage caused by the ground support feet. At the same time, the ground support feet can better assist the operator in maintaining a suitable distance between the road marking measurement body and the light source body and the ground markings, ensuring the measurement effect of the equipment.

[0024] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] Reference Figures 1-6 A configurable light source for a road marking measurement device includes a road marking measurement body 1, with a light source body 2 fixed to one end of the road marking measurement body 1. The light source body 2 is magnetically attached to one end of the road marking measurement body 1. The inner wall of the light source body 2 is provided with a lamp plate 201, a frame 202, and a light-transmitting plate 203. The light-transmitting plate 203, the frame 202, and the lamp plate 201 are sequentially passed through by lamp plate screws 204 and threadedly fixed to the inner wall of the light source body 2. The road marking measurement body 1 and the light source body 2 are connected and fixed by magnetic attraction, allowing the light source body 2 to be quickly disassembled and assembled. The light source can be quickly replaced for different detection scenarios. When the light source module is upgraded individually, it is not necessary to replace the entire detection device, reducing user costs. At the same time, this method adjusts the light source model and brightness parameters by replacing hardware, so that the staff does not need to make adjustments through software, reducing the experience and training required for the staff. The staff only needs simple training to disassemble and replace the light source, greatly lowering the threshold for use.

[0027] The inner wall of the road marking measuring body 1 near the light source body 2 is fixed with a connecting base 3 via a fixing screw hole 306. A magnetic connector female head 302 is fixed at one end of the connecting base 3 near the light source body 2. A guide hole 301 is opened at one end of the connecting base 3. Multiple guide holes 301 are opened at the end of the road marking measuring body 1 near the light source body 2. A magnetic connector male head 303 is provided at the end of the light source body 2 near the road marking measuring body 1. A guide shaft 304 is fixed at one end of the connecting base 3. The guide holes 301 and the guide shaft 304 guide and position the two to ensure a stable connection and prevent them from shifting. The magnetic connector female head 302 and the magnetic connector male head 303 are fixed on the connecting base 3 and the light source body 2 of the road marking measuring body 1, respectively. They are connected by magnetic attraction during assembly without the need for manual connection.

[0028] An internal bearing 305 is fixed to the inner wall of the guide hole 301. The internal bearing 305 is not integrated with the guide hole 301 of the connecting base 3, and is made of polymer material or rubber material. This allows the internal bearing 305 to produce a certain buffering effect when the guide shaft 304 is inserted into the guide hole 301, preventing damage to the connecting base 3 and the guide hole 301.

[0029] Multiple hollow magnets 401 are fixed to one end of the light source body 2 near the road marking measuring body 1 by magnetic screws 4. Multiple base magnets 402 are fixed to the connecting base 3 at the corresponding positions of the hollow magnets 401. Through the corresponding attraction between the hollow magnets 401 and the magnetic screws 4, the road marking measuring body 1 and the light source body 2 are fixed by magnetic force, which helps to eliminate the tiny gaps between the two, increases the fixing effect, facilitates disassembly and assembly, and at the same time eliminates the tiny gaps so that dust cannot enter the connection between the two, prevents poor contact caused by dust entering the connection port, and ensures the stability of the equipment.

[0030] The bottom of the light source body 2 is fixed with a ground support foot 5. The ground support foot 5 can prevent the light source body 2 from falling and directly colliding with the ground during use. At the same time, the ground support foot 5 can help the staff maintain a proper distance between the road marking measurement body 1 and the light source body 2 and the ground marking.

[0031] The bottom of the ground support foot 5 is covered with a rubber layer, which provides cushioning and isolation to prevent the ground support foot 5 from directly colliding with the ground and causing wear and damage.

[0032] The thickness of the road marking measuring body 1 at the corresponding locations of the base magnet 402 and the hollow magnet 401 is less than the thickness at other locations of the road marking measuring body 1. By reducing the thickness of the road marking measuring body 1 at the corresponding locations of the base magnet 402 and the hollow magnet 401, the base magnet 402 and the hollow magnet 401 can be magnetically attracted more tightly by magnetic force.

[0033] The working principle of this utility model is as follows: When the operator needs to install the light source body 2 into the road marking measurement body 1, the guide shaft 304 of the light source body 2 is aligned with the guide hole 301 of the road marking measurement body 1, and the magnetic connector male head 303 of the light source body 2 is aligned with the magnetic connector female head 302 of the road marking measurement body 1. Simultaneously, the hollow magnet 401 and the base magnet 402 are magnetically fixed together. This allows operators to easily install, disassemble, and replace the light source with only simple training, greatly lowering the barrier to entry. When the operator needs to replace or disassemble the light source body 2, they only need to pull the light source body 2 outwards. The guide shaft 304 is designed for easy disassembly and also serves as a power connection. It is inserted into the guide hole 301 and simultaneously connected to the contact point of the road marking measurement body 1. The light source body 2 has a built-in power supply and control circuit, eliminating the need for electrical signal connection with the road marking measurement body 1. This allows the light source body 2 to be separated from the road marking measurement body 1. The light source body 2 and the road marking measurement body 1 can be quickly connected while simultaneously completing the electrical signal connection. This enables the switching of different light source bodies 2 at the hardware level, decoupling the light source control logic from the detection equipment. For example, a standardized communication protocol allows the same light source module to be compatible with equipment from different manufacturers.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
