Description

Technical Field

[0001] This application relates to the field of license plate mounting devices, and in particular to a license plate mounting device with auxiliary lighting function. Background Technology

[0002] The field of vehicle parts technology has developed rapidly in recent years, especially in improving nighttime driving safety. Current vehicle lighting systems mainly consist of headlights, fog lights, and side marker lights, whose illumination range and brightness are limited by lamp design specifications and installation locations. Although some high-end models are equipped with adaptive high beams or laser headlights, these technologies are expensive and difficult to popularize in ordinary models, limiting their widespread application. Furthermore, with the rise of vehicle modification culture, car owners have increasingly higher demands for safety and personalization during nighttime driving, leading to a growing market demand for auxiliary lighting devices. Especially in complex road conditions and inclement weather, how to fully utilize the space of the license plate area to achieve efficient and convenient auxiliary lighting has become a pressing technical problem. To address the problem of insufficient nighttime lighting, the market typically uses illuminated license plate mounting structures, which mainly include a license plate frame adapted to the vehicle body structure, the license plate itself, and lighting components. The principle is to fix the license plate within the license plate frame and connect it to the vehicle's lighting system to achieve auxiliary vehicle illumination. While illuminated license plate mounting structures utilize the space of the license plate area, significant problems still exist in some practical applications. Existing license plate lighting installation structures have significant drawbacks: During driving, sudden adverse weather conditions such as fog, rain, snow, or poor road conditions may occur. The single illumination angle of the license plate lights results in poor lighting performance, failing to meet drivers' needs for high road visibility. In complex road conditions, low road clarity severely impairs drivers' judgment of the road ahead, thus affecting driving safety. Existing lighting components are typically fixed in place, making it difficult to flexibly adjust the light's illumination of the road surface according to actual needs in case of sudden adverse weather conditions, further limiting their applicability and practicality. These issues indicate that traditional lighting enhancement solutions still have considerable room for improvement in terms of convenience, safety, and functionality. Utility Model Content

[0003] In order to enable flexible adjustment of the headlight beam angle, ensure the illumination effect of the headlight assembly under multi-angle illumination, and quickly and conveniently complete the adjustment of the headlight beam to improve driving safety, a license plate mounting device with auxiliary lighting function is provided.

[0004] A license plate mounting device with auxiliary lighting function includes a fixed bracket and a lighting device detachably mounted on the fixed bracket. The fixed bracket is used for mounting on a vehicle and includes a license plate frame and a light frame. The lighting device includes a lighting component connected to the vehicle's lighting system and an adjustment component. The adjustment component includes an adjustment knob for adjusting the illumination angle of the lighting component, and the adjustment knob is mounted on the outer surface of the fixed bracket. By adopting this technical solution, the fixed bracket can be securely mounted on the vehicle while providing independent installation space for the license plate and the lighting device. The license plate frame is used to hold the license plate, ensuring it will not loosen or fall off during driving, thus guaranteeing the clear visibility of the vehicle identification. The light frame is specifically designed to hold the lighting device, allowing the lighting component to be tightly integrated with the license plate area, making full use of the space around the vehicle's license plate. The lighting component is connected to the vehicle's lighting system, enabling coordinated operation with the overall vehicle lighting system to ensure timely auxiliary lighting when needed. More importantly, the introduction of the adjustment component significantly improves the flexibility of the lighting function and driving safety. Through the adjustment knob, the user can manually adjust the illumination angle of the lighting component to adapt to different driving environments and weather conditions. For example, in rainy or snowy weather or complex road conditions, the direction of light projection can be quickly and conveniently changed by adjusting the adjustment knob, avoiding glare caused by direct light hitting water or snow on the road surface, thereby improving the driver's accuracy in judging road conditions. This effectively reduces safety hazards caused by a single illumination angle, providing a safer and more reliable auxiliary lighting solution for nighttime driving. Preferably, the adjustment component further includes a rotating component and a rotary drive component. The rotating component is connected to the lighting component, and the rotary drive component drives the rotating component to rotate. The adjustment knob passes through the side wall of the fixed bracket and is fixedly connected to the rotary drive component. By adopting the above technical solution, the rotating component is fixedly connected to the lighting component, so that the rotation of the rotating component can directly drive the lighting component to change the illumination angle. The rotary drive component is connected to the rotating component, further transmitting the rotational action of the adjustment knob to the rotating component, thereby achieving precise adjustment of the lighting component angle. When the user rotates the adjustment knob, the knob drives the rotating component to rotate via the internal transmission structure of the rotary drive. The rotary drive and the rotating component can flexibly and selectively select and engage, thereby changing the illumination direction of the lighting assembly and stabilizing it at a tilt angle. This design not only allows for flexible adjustment of the light's illumination range but also ensures that, under complex road conditions or inclement weather, drivers can quickly optimize road lighting effects according to actual needs, improving the safety and comfort of nighttime driving.Preferably, the rotating drive component includes a gear, a rotating shaft, and a spring. The two ends of the rotating shaft are fixedly connected to the gear and the adjusting knob, respectively. The spring is sleeved on the rotating shaft and abuts against the inner sidewalls of the gear and the fixed bracket, respectively. The rotating component has a cavity, a first rotating part, and a second rotating part. The second rotating part is connected to the fixed bracket, and the first rotating part is connected to the lighting assembly and rotatably connected to the rotating part. The cavity is located in the first rotating part. The inner wall of the cavity has a gear shape corresponding to the outline of the gear. The first rotating part has a groove, and the gear has a protrusion corresponding to the groove. By adopting the above technical solution, the specific working principle is as follows: the rotating shaft acts as a connecting hub, with both ends fixedly connected to the gear and the adjusting knob, respectively. The spring is sleeved on the rotating shaft, with both ends abutting against the inner sidewalls of the gear and the fixed bracket, providing elastic support for the gear and allowing it to mesh tightly with the gear shape on the inner wall of the rotating component's cavity in its natural state. The rotating component includes a cavity, a first rotating part, and a second rotating part. The second rotating part is connected to a fixed bracket, and the first rotating part is connected to the lighting assembly and can rotate around the second rotating part. The cavity is located within the first rotating part and has a gear-shaped inner wall. The first rotating part also has a groove, and the gear plate has a corresponding protrusion. When the angle of the lighting assembly needs to be adjusted, the user pulls out the adjustment knob forcefully, overcoming the spring force and temporarily disengaging the gear plate from the gear on the inner wall of the cavity. At this time, the adjustment knob can be freely rotated, and the rotating shaft drives the gear plate to rotate synchronously. The protrusion on the gear plate cooperates with the groove of the first rotating part, driving the first rotating part and the second rotating part to rotate relative to each other, thereby driving the lighting assembly to rotate to adjust the angle. When the angle is adjusted to the correct position, the adjustment knob is released. Under the action of the spring's elastic restoring force, the gear plate re-engages tightly with the gear on the inner wall of the cavity, and at the same time, the protrusion engages with the groove, precisely locking the lighting assembly at the current angle to ensure its stable position.

[0005] This ingenious and practical structure cleverly combines gear plates, a rotating shaft, a spring, and the gear-shaped cavity and raised groove structure on the rotating component to achieve the dual functions of adjusting the lighting component's angle and precisely locking it. On one hand, the gear meshing principle and the raised groove locking structure allow for flexible and stable adjustment of the lighting component's illumination angle, meeting diverse lighting needs in different scenarios and greatly improving usability and convenience. On the other hand, the spring's elasticity ensures a tight fit between the gear plate and the gear on the inner wall of the cavity, providing reliable support for the locked state after angle adjustment. This effectively prevents the lighting component from accidentally shifting due to external forces or its own weight, ensuring the stability and reliability of the lighting angle. Simultaneously, the overall structure is compact and easy to operate, providing users with a superior user experience. Preferably, there are two symmetrical adjustment knobs, each passing through both sides of the fixed bracket and connected to the rotating component. By adopting the above technical solution, the two symmetrical adjustment knobs can drive the rotating component from both sides, thereby achieving bidirectional adjustment of the lighting component's illumination angle. This design not only improves the convenience of adjustment operation but also ensures the stability of the adjustment process. When adjusting the lighting angle, the user can rotate either adjustment knob, which in turn drives the rotating component to change the angle of the lighting assembly. Furthermore, the symmetrical distribution of the two adjustment knobs allows the user to choose the more convenient side for operation, further enhancing the device's practicality and flexibility. In addition, the bidirectional adjustment design provides drivers with a more convenient adjustment method in complex road conditions or inclement weather, significantly improving nighttime driving safety. Preferably, the outer surface of the adjustment knob is provided with anti-slip protrusions. By adopting the above technical solution, the anti-slip protrusions on the outer surface of the adjustment knob effectively increase the friction between the user's hand and the adjustment knob. In actual operation, when adjusting the illumination angle of the lighting assembly, the user needs to rotate the adjustment knob. Without an anti-slip design, sweaty or wet hands may cause slippage, affecting adjustment accuracy and convenience. With the addition of anti-slip protrusions, even in complex environments such as wet or oily conditions, the user can firmly grip the adjustment knob, ensuring smooth application of rotational force, thereby achieving precise control of the illumination angle of the lighting assembly and improving the overall user experience and safety of the device. Preferably, the lamp frame is a trapezoidal truncated pyramid structure, and the outer surface of the lamp frame near the license plate is an inclined surface. By adopting the above technical solution, the lamp frame is designed as a trapezoidal truncated pyramid structure, and the outer surface near the license plate is set as an inclined surface, which can effectively increase the light scattering angle of the lighting components. Because the trapezoidal truncated pyramid structure lamp frame has a specific geometric shape, its inclined surface can guide light to be emitted outward with a wider distribution range, thereby avoiding the problem of blind spots caused by excessive light concentration.This design not only enhances the overall brightness of the license plate area but also provides more uniform auxiliary lighting around the vehicle in complex road conditions or inclement weather, further improving nighttime driving safety. Furthermore, the sloping surface design reduces light reflection interference with the driver's vision, ensuring both lighting effectiveness and driving comfort. Preferably, a latching element is provided on one side of the license plate frame for securing the license plate. By adopting the above technical solution, the latching element on one side of the license plate frame effectively secures the license plate. Specifically, when the license plate is inserted into the license plate frame, the latching element, through its own elastic deformation or mechanical locking action, firmly secures the license plate within the frame, preventing it from loosening or falling off due to vibration or external impact during vehicle operation. This design not only improves the stability of license plate installation but also simplifies the installation and removal process, making it more convenient for users to replace or clean license plates. Simultaneously, the latching element avoids the operational complexity associated with bolts or other traditional fixing methods, further enhancing the practicality and reliability of the overall device. Preferably, the license plate frame is provided with a sliding track, and the outer surface of the sliding track is provided with an abutment portion. The license plate is inserted into the license plate frame along the sliding track and abuts against the abutment portion. By adopting the above technical solution, the sliding track provides a convenient guiding path for license plate installation. Specifically, when the license plate is inserted from one side of the license plate frame, the sliding track can guide the license plate smoothly into the license plate frame, avoiding tilting or jamming of the license plate due to improper installation. At the same time, the abutment portion on the outer surface of the sliding track plays a limiting role during license plate insertion, ensuring that the license plate finally abuts tightly against the abutment portion, thereby achieving a stable installation of the license plate. This design not only improves the efficiency of license plate installation, but also effectively prevents the license plate from loosening or falling off during driving, improving the reliability and safety of the overall device. Preferably, the lighting component includes a lamp housing installed inside the lamp frame, a PCB assembly disposed inside the lamp housing, a lamp shade covering the opening of the lamp housing, and a power connector connected to the automotive lighting system. The power connector passes through the lamp housing and connects to the PCB assembly. By adopting the above technical solution, the lamp housing in the lighting assembly is installed inside the lamp frame, forming effective protection for the light source and providing a stable mounting base. The PCB assembly is set inside the lamp housing and, as the core control component of the light source, enables precise control of the light. The lamp shade covers the opening of the lamp housing, not only providing dust and water protection but also optimizing the light distribution, allowing the light to illuminate the target area more evenly. The power connector passes through the lamp housing and connects to the PCB assembly, ensuring that the lighting assembly can stably obtain power from the automotive lighting system, thereby achieving efficient and reliable auxiliary lighting functions. This structural design enables the lighting assembly to meet basic lighting needs while possessing good protective performance and electrical connection stability, significantly improving driving safety at night or in adverse weather conditions. Preferably, the lamp shade protrudes from the outer surface of the lamp frame.By adopting the above technical solution, the design of the lampshade protruding from the outer surface of the lamp frame effectively expands the light emission range of the lighting components. Because the lampshade protrudes from the lamp frame, the obstruction encountered by light during propagation is reduced, allowing the light to cover the surrounding area more evenly. Furthermore, this design can also protect the lampshade from external impacts or scratches to a certain extent, extending the lifespan of the lighting components. In practical use, this structural optimization not only improves the lighting effect but also enhances the durability of the device, providing safer and more reliable auxiliary lighting for nighttime driving.

[0006] In summary, this application includes at least one of the following beneficial technical effects:

[0007] 1. By installing an adjustable illumination angle lighting device on a fixed bracket, users can flexibly adjust the direction of the light beam according to actual road conditions and weather conditions. Specifically, the adjustment knob, rotating component, and rotary drive component in the adjustment assembly work together to precisely control the angle of the lighting assembly. This design effectively solves the problem that traditional fixed lighting fixtures cannot adapt to complex environments, and also provides a way to quickly adjust the light using only a knob, thereby significantly improving nighttime driving safety;

[0008] 2. The adjustment mechanism is manually operated, allowing for precise adjustment of the lighting angle through a simple mechanical structure. Anti-slip protrusions on the outer surface of the adjustment knob enhance the operating feel, while internal components such as gears, shafts, and springs ensure structural stability and reliability. This design simplifies the operation process and adapts to the modification needs of different vehicle models, making it widely applicable. Attached Figure Description

[0014] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0015] This application discloses a license plate mounting device with auxiliary lighting function, referring to... Figure 1 and Figure 2 The installation device includes a fixed bracket 1 and a lighting device 2 detachably mounted on the fixed bracket 1. The lighting device 2 includes a lighting component 21 detachably mounted on the fixed bracket 1 and an adjustment component 22. The lighting component 21 is used to emit a light beam, and the adjustment component 22 is used to adjust the illumination angle of the lighting component 21.

[0016] Reference Figure 1 Specifically, the mounting bracket 1 is used for installation on a car and can be divided into a main frame and side panels. The main frame has a rectangular structure and is divided from top to bottom into a license plate frame 11 for placing the license plate and a lamp frame 12 for placing the lighting components 21. Both are rectangular open frame structures, and the main frame is made of a material with high strength and light weight. The side panels are connected to the main frame by welding to form an integral structure that can be firmly installed on the car. The surface of the main frame is provided with a fastener 13 for fixing the license plate. The fastener 13 is made of elastic plastic and cooperates with the license plate through a slot to ensure that the license plate is installed firmly. In addition, the surface of the main frame is also provided with a sliding rail 14. The outer surface of the sliding rail 14 is provided with an abutment part 15. The sliding rail 14 is used to accommodate the license plate. The license plate can be inserted from one side along the sliding rail 14 and abut against the abutment part 15, which not only facilitates the installation and removal of the license plate but also effectively prevents the license plate from easily coming loose.

[0017] The light frame 12 has a trapezoidal structure, with an inclined surface near the license plate. The angle between the inclined surface and the bottom surface of the light frame 12 can be designed to be 60°-75°, allowing the light to illuminate the license plate area and the surrounding environment more evenly. The light frame 12 houses the lighting component 21. The light frame 12 is bolted to the main frame, and rubber gaskets are provided at the connection points to prevent rainwater from seeping in.

[0018] Reference Figure 3 and Figure 4Specifically, the adjustment assembly 22 includes an adjustment knob 221 for adjusting the illumination angle of the lighting assembly 21, a rotating component 222, and a rotation drive component 223. The adjustment knob 221 passes through the side wall of the fixed bracket 1 and is connected to the rotation drive component. The rotating component 222 is connected to the lighting assembly 21. Rotating the adjustment knob 221 controls the rotation drive component to rotate the rotating component 222, thereby causing the lighting assembly 21 connected to the rotating component 222 to rotate.

[0019] The rotary drive component 223 in this embodiment consists of a gear plate 223a, a rotating shaft 223b, and a spring 223c. The two ends of the rotating shaft 223b are securely connected to the gear plate 223a and the adjusting knob 221, respectively. The spring 223c is sleeved on the outside of the rotating shaft 223b. The spring 223c and the adjusting knob 221 are located on both sides of the side wall plate. The two ends of the spring 223c are in close contact with the gear plate 223a and the inner side wall of the fixed bracket 1, respectively, to provide buffering and resetting functions.

[0020] In this embodiment, the rotating component 222 is divided into a first rotating part 222b and a second rotating part 222c. The first rotating part 222b is mounted on the lighting assembly, and the second rotating part 222c is mounted on the side wall of the fixed bracket. The first rotating part 222b and the second rotating part 222c are rotatably connected. The first rotating part 222b has an internal cavity 222a. The inner wall of the cavity 222a is carefully machined to match the gear shape of the gear plate 223a. A groove is provided on one end face of the first rotating part 222b near the gear plate 223a, and correspondingly, a protrusion is provided on the gear plate 223a. Specifically, the initial position of the gear plate 223a is inside the cavity 222a. When it is necessary to adjust the illumination angle of the lighting component 21, the user can pull the adjustment knob 221 to make the gear plate 223a move outward against the force of the spring 223c. At this time, the gear plate 223a is still engaged with the gear-shaped cavity 222a. The user can freely rotate the adjustment knob 221. The adjustment knob 221 drives the gear plate 223a to rotate through the rotating shaft 223b. The gear plate 223a then drives the first rotating part 222b to rotate through the meshing relationship. In turn, the first rotating part 222b and the second rotating part 222c rotate relative to each other, thereby realizing the adjustment of the illumination angle of the lighting component 21. After adjusting to a suitable angle, the adjustment knob 221 is released, the spring 223c returns to its original position, and the lighting component 21 is fixed in the current position by the engagement of the protrusion a and the groove b. The adjustment knob 221 is installed on the outer surface of the fixed bracket 1, which achieves the effect of improving nighttime driving safety and flexibly adjusting the illumination angle. In this embodiment, the groove b is an annular groove b, the groove surface of the groove b is an arc-shaped groove surface, and the protrusion a is an arc-shaped protrusion a that matches the arc-shaped groove surface, which is beneficial to expanding the range of adjustable angle of the light.

[0021] In this embodiment, there are two adjustment knobs 221, symmetrically arranged on the outer surfaces of the two side walls of the fixed bracket 1. The two adjustment knobs 221 pass through the side walls of the fixed bracket 1 and are connected to the rotating component 222. The outer surface of the adjustment knobs 221 is provided with anti-slip protrusions, which are distributed circumferentially along the outer surface of the adjustment knobs 221, facilitating driver operation and effectively preventing hand slippage. Specifically, the lighting assembly 21 also includes a lamp housing, a PCB assembly, a lamp shade, and a power connector. The lamp housing is installed inside the lamp frame 12, the PCB assembly is located inside the lamp housing, the lamp shade covers the opening of the lamp housing, and the power connector is connected to the automotive lighting system. The first rotating part 222b is fixedly connected to the surface of the lamp housing. The lamp housing, PCB assembly, lamp shade, and power connector are assembled one by one to form a light-emitting lighting assembly 21. The lamp housing is made of aluminum alloy, which has good heat dissipation performance, and its surface is anodized to improve corrosion resistance. Multiple LED beads are installed on the PCB assembly, and the beads are connected by wires to form a complete circuit. The lampshade is made of transparent polycarbonate material, which has high light transmittance and impact resistance. In particular, the lampshade is designed to protrude from the outer surface of the lamp frame 12, further expanding the illumination range. The implementation principle of this embodiment is as follows: The license plate mounting device consists of a fixed bracket 1 and a lighting device 2 detachably mounted on it. The lighting device 2 includes a lighting component 21 and an adjustment component 22. The main frame of the fixed bracket 1 is a rectangular structure, dividing the license plate frame 11 and the lamp frame 12. Both are made of high-strength lightweight materials, and the surface is provided with elastic plastic fasteners 13 and sliding rails 14 with abutment parts 15, which facilitates the stable installation and removal of the license plate. The side wall panels are welded to the main frame as a whole, which can be firmly installed in the car. The lamp frame 12 is a trapezoidal platform structure, inclined at 60°-75° near the outer surface of the license plate, and the lighting component 21 is placed inside the cavity 222a.The adjustment assembly 22 includes an adjustment knob 221, a rotary drive 223, and a rotating component 222. Two adjustment knobs 221 are symmetrically arranged on the outer surfaces of the side walls of the fixed bracket 1, with circumferentially distributed anti-slip protrusions on their outer surfaces, penetrating the side walls and connecting to the rotary drive 223. The rotary drive 223 consists of a gear 223a, a rotating shaft 223b, and a spring 223c. The rotating shaft 223b is securely connected to the gear 223a and the adjustment knob 221 at both ends. The spring 223c is sleeved on the rotating shaft 223b, with both ends tightly abutting against the gear 223a and the inner side wall of the fixed bracket 1, serving as a buffer and resetting mechanism. The rotating component 222... The lighting assembly 21 has a cavity 222a that matches the shape of a gear plate 223a, and includes a first rotating part 222b and a second rotating part 222c that are rotatably connected. The first rotating part 222b is mounted on the lighting assembly 21 and has an annular groove (the groove surface is arc-shaped). The gear plate 223a has an arc-shaped protrusion. By pulling the adjustment knob 221, the gear plate 223a engages with the first rotating part 222b. Rotating the adjustment knob 221 can drive the lighting assembly 21 to rotate to adjust the illumination angle. After releasing, the spring 223c returns to its original position, and the arc-shaped protrusion engages with the arc-shaped groove to fix the lighting assembly 21. This design helps to expand the adjustable angle range of the light. This device can improve nighttime driving safety and achieve flexible adjustment of the illumination angle.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
