Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle lighting, specifically relating to a license plate light suitable for electric vehicles and an electric vehicle equipped with the license plate light. Background Technology

[0002] With the widespread adoption of electric vehicles, rear-mounted lighting devices such as license plate lights, taillights, and side marker lights have become essential for ensuring driving safety and regulatory compliance. The primary function of license plate lights is to illuminate the rear license plate, ensuring clear visibility at night or in low-light conditions to meet the visibility requirements of traffic management departments. However, as users' demands for personalization and aesthetics in electric vehicles continue to increase, more and more vehicles are seeking more diverse visual effects beyond basic lighting functions, such as projecting patterns or logos onto the ground to enhance brand recognition or decorative appeal.

[0003] Currently, there are two common solutions on the market:

[0004] One type is a single license plate light structure, which only fulfills the function of illuminating the license plate and cannot achieve ground projection. It has a single function and lacks additional visual effects.

[0005] Another type involves placing the projection lamp separately at the rear of the vehicle. While this can achieve pattern projection, it typically requires additional installation space, a dedicated housing, and electrical connections. The structure is fragmented, assembly is complex, and it is prone to inaccurate projection direction or blurry patterns due to vibration or structural misalignment, resulting in poor reliability. Furthermore, existing lamp support structures for projection are often quite simple, failing to adequately guide or fix the projection angle. This makes it difficult to accurately align the light source with the transparent cover outlet, thus affecting projection clarity and stability.

[0006] On the other hand, given the complex operating environment of electric vehicles (such as vibration, rain, dust, etc.), traditional license plate light products also have shortcomings in terms of housing sealing and connection stability, which can easily lead to water leakage, loosening, or dust ingress, affecting service life and safety performance.

[0007] Therefore, the existing technology still lacks an electric vehicle license plate light structure that is compact, easy to install, has dual functions of license plate illumination and pattern projection, and can stably achieve a preset projection direction and good sealing performance. This is precisely the technical problem that this utility model aims to solve. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated license plate light and projection light module suitable for electric vehicles, which improves the overall lighting and aesthetics of electric vehicles, as well as an electric vehicle equipped with the license plate light.

[0009] To solve the above-mentioned technical problems, the technical method adopted by the present invention is as follows: The present invention discloses a license plate light suitable for electric vehicles, including an upper cover, a lower cover matching the upper cover, and a license plate light. The license plate light is disposed within the closed space formed by the upper cover and the lower cover. The upper cover has an electric vehicle fixing interface for connection with the electric vehicle at its end. It also includes a projection light. The lower cover has a transparent cover for the license plate light and a transparent cover for the projection light, and the angle between the transparent covers for the projection light and the transparent cover for the projection light in the clockwise direction is an obtuse angle.

[0010] Furthermore, the projection lamp is fixed to the upper cover by a projection lamp bracket, and the light source of the projection lamp is directly facing the transparent projection lamp cover.

[0011] Furthermore, the projection lamp bracket includes a first connecting fixing plate, a projection lamp fixing stud, and a second connecting fixing plate;

[0012] The upper cover is respectively provided with a first fixing thread post and a second fixing thread post that match the first connecting fixing plate and the second connecting fixing plate.

[0013] Furthermore, a reinforcing rib is provided along the outer end face of the first fixed threaded post to connect to the upper cover.

[0014] Furthermore, the interface between the upper and lower covers is sealed.

[0015] Furthermore, the projection lamp is fixed to the projection lamp fixing stud by self-tapping screws.

[0016] Furthermore, the self-tapping screw has a diameter of 3 mm.

[0017] Furthermore, the projection lamp bracket includes a first bottom surface and a second bottom surface inclined to the first bottom surface;

[0018] The angle between the second bottom surface and the first bottom surface in a clockwise direction is an obtuse angle;

[0019] The bottom end of the projection lamp fixing stud is set on the connection line between the second bottom surface and the first bottom surface, and is connected to the second bottom surface and the first bottom surface respectively;

[0020] Reinforcing ribs connecting the first bottom surface and the second bottom surface are respectively provided along the outer end face of the projection lamp fixing stud.

[0021] Furthermore, the second connecting fixing plate protrudes from the projection lamp bracket body, and the second connecting fixing plate has a groove that can accommodate the second fixing threaded post.

[0022] The present invention also discloses an electric vehicle, wherein the rear end of the electric vehicle is provided with any of the above-mentioned license plate lights suitable for electric vehicles. Beneficial effects

[0023] 1. This utility model introduces an independently mounted projection lamp into the traditional license plate light structure, and integrates a license plate light cover and a projection lamp cover mounted on the lower cover. The angle between the two covers, rotating clockwise, is obtuse. This allows the license plate light beam to be directly facing the license plate area, while the projection light beam is projected onto the ground to form a logo or pattern display. This structure enables a single lamp to perform two functions, balancing traffic compliance with aesthetic customization needs and enhancing the overall vehicle design. Compared to traditional single lighting devices, this utility model achieves an organic integration of functions through this angled design and lamp body integration.

[0024] 2. In this utility model, the projection lamp bracket consists of a first bottom surface and an inclined second bottom surface, with an obtuse angle formed between the two bottom surfaces in a clockwise direction. A first connecting fixing plate is disposed on the first bottom surface for fixing to the upper cover, and a second connecting fixing plate is disposed on the second bottom surface for connecting to another fixing point. Projection lamp fixing studs are disposed on the connecting line between the first and second bottom surfaces, forming an axis that supports the projection direction. This structure ensures that the light source direction of the projection lamp naturally aligns with the transparent cover during installation, guaranteeing the accuracy of the pattern projection direction. Furthermore, by distributing connecting plates on two bottom surfaces with different inclination angles, the stress is effectively dispersed, improving the overall connection rigidity and vibration resistance, preventing projection offset or loosening due to vibration or collision during vehicle operation, thereby improving the stability of the pattern projection and the overall vehicle reliability.

[0025] 3. This utility model features a sealing structure at the interface between the upper and lower covers, connected to the projection lamp fixing studs via self-tapping screws. The screws are preferably 3 mm in diameter, ensuring both fixing strength and facilitating quick assembly. Combined with reinforcing ribs on the outer surface of the upper cover, the overall lamp body possesses high waterproof, dustproof, and impact resistance capabilities, adapting to the complex environment frequently encountered by the rear of electric vehicles, including rain, flying stones, and vibrations. Simultaneously, the second connecting fixing plate has grooves that tightly engage with the second fixing threaded studs, further enhancing structural stability and installation accuracy, ensuring consistency and assembly efficiency during mass production.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: A license plate light suitable for electric vehicles

[0032] like Figures 1 to 4 As shown, this embodiment provides a license plate light suitable for electric vehicles, including:

[0033] The upper cover 1, the lower cover 5 that matches the upper cover 1, and the license plate light 4 are arranged in a closed space formed by the upper cover 1 and the lower cover 5, and are used to illuminate the license plate area at the rear of the electric vehicle at night.

[0034] The upper cover 1 has an electric vehicle fixing interface 10 at its end, which is used to reliably install the license plate light structure at the corresponding connection part at the rear of the electric vehicle.

[0035] This embodiment also includes a projection lamp 3 for illuminating the ground. The projection lamp 3 is disposed inside the upper cover 1 and fixed by a projection lamp bracket 2. The projection lamp bracket 2 includes a first connecting fixing plate 21, a second connecting fixing plate 23, and an inclined bottom structure connecting the two.

[0036] Specifically, the projector lamp holder 2 includes:

[0037] A first bottom surface 201 and an inclined second bottom surface 202, wherein the second bottom surface 202 is inclined at an obtuse angle relative to the first bottom surface 201 in a clockwise direction;

[0038] The projection lamp fixing stud 22 is set on the connection line between the second bottom surface 202 and the first bottom surface 201, and is fixed to both at the same time;

[0039] The first connecting and fixing plate 21 is disposed on the first bottom surface 201;

[0040] The second connecting and fixing plate 23 is disposed on the second bottom surface 202.

[0041] The above structural arrangement allows the projection lamp 3 to be stably fixed on the inclined mounting surface, thereby ensuring that its light source direction is directly facing the projection lamp transparent cover 7 on the lower cover 5.

[0042] The lower cover 5 features two light-transmitting structures: a license plate light transparent cover 6 and a projection light transparent cover 7. These two structures form a clockwise obtuse angle when mounted on the lower cover, concentrating the license plate light illumination area on the license plate surface and the projection light illumination area on the ground beneath the vehicle. This structure not only meets the regulatory requirements for license plate illumination but also enhances the ground projection effect, allowing for the projection of signs, logos, or warning patterns, thus improving the vehicle's overall personalization and safety.

[0043] Preferably, in order to ensure the fastening stability of the projection lamp 3 and the projection lamp bracket 2, the projection lamp 3 is connected to the projection lamp fixing stud 22 by self-tapping screws. The diameter of the self-tapping screws is preferably 3 mm, which can meet the installation strength requirements of the small vehicle lamp fixing structure.

[0044] Preferably, the upper cover 1 is further provided with a first fixed threaded post 11 and a second fixed threaded post 12, which are respectively used to screw into the first connecting fixing plate 21 and the second connecting fixing plate 23, thereby further improving the structural stability between the projection lamp bracket and the lamp body.

[0045] More preferably, to further enhance structural strength, a reinforcing rib connecting the upper cover 1 is provided on the outer end face of the first fixed threaded post 11. Similarly, reinforcing ribs are also provided on the outer end face of the projection lamp fixed stud 22 to connect the first bottom surface 201 and the second bottom surface 202, thereby enhancing the deformation resistance of the entire bracket under stress.

[0046] Preferably, in order to prevent rainwater, dust and other impurities from entering the lamp body, a sealing structure is provided at the interface between the upper cover 1 and the lower cover 5, which can be sealed by filling with rubber rings or sealant.

[0047] In this embodiment, to ensure the normal illumination of the license plate light 4 and the projection light 3, a power wire channel is reserved inside the upper cover 1. The projection light 3 and the license plate light 4 are respectively connected to the power system at the rear of the electric vehicle via wires, preferably connected to the vehicle's 12V DC power supply system, powered by the electric vehicle's battery. The license plate light and the projection light can be controlled separately via independent circuits, or they can be linked with the electric vehicle's taillight system to illuminate synchronously.

[0048] The power cord can be connected to the pre-installed interface at the rear of the electric vehicle via a plastic plug-in connector, facilitating installation and subsequent maintenance. For safety, a current-limiting resistor or fuse can be connected in series in the circuit to prevent short circuits or overcurrent from burning out the lighting components.

[0049] In addition, to facilitate the switching of projected patterns, the projector can use an LED light source module with a reserved pattern slider inside, allowing users to change different projected patterns as needed, thereby improving the visual recognition and nighttime warning effect of the rear of the electric vehicle.

[0050] Example 2: An electric vehicle

[0051] In this embodiment, the rear end of the electric vehicle is provided with a license plate light suitable for electric vehicles as described in Embodiment 1 above. The license plate light is installed on the rear structure of the vehicle through the electric vehicle fixing interface 10. It has a stable structure, is easy to install, and has good lighting and ground projection functions, which can improve the aesthetics and safety of the whole vehicle.

[0052] The electric vehicle using this embodiment can simultaneously illuminate the license plate and project a pattern onto the ground when driving at night, enhancing vehicle visibility and facilitating safe driving at night.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
