Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, specifically to a high-transmittance automotive lighting module with high shock resistance and vibration damping. Background Technology

[0002] With the rapid development of the automotive industry, vehicle applications are becoming increasingly diversified, extending from smooth urban roads to rugged off-road sections and bumpy rural roads, and from ordinary passenger cars to heavy trucks, special-purpose vehicles, and new energy off-road vehicles. As a core component ensuring driving safety, vehicle lights operate in increasingly complex environments. They not only need to provide clear and stable illumination at night and in adverse weather conditions such as rain and fog, but also must withstand the continuous vibrations, temperature fluctuations, and corrosion from external dust and moisture generated during vehicle operation. Especially in scenarios such as long-distance transportation, off-road exploration, and special operations, the shock resistance, heat dissipation efficiency, and sealing performance of vehicle light modules directly affect the clarity of the driver's vision and the overall reliability of vehicle operation, becoming key indicators for measuring the core competitiveness of vehicle light products.

[0003] Currently, most automotive lighting modules on the market are equipped with shock-resistant components to meet the needs of normal driving. Existing solutions mostly use elastic components such as rubber buffer pads and coil springs to absorb the vibration energy transmitted by the vehicle through the elastic deformation of the components, reducing the direct impact of vibration on core components such as light sources and circuits. Positioning structures are usually set between the lamp body and the lamp housing and the body mounting position to limit excessive displacement of the lamp body. In terms of sealing, rubber sealing rings are mostly used to achieve a close fit between the lamp body and the lamp housing and the body, preventing dust and moisture from entering.

[0004] Existing anti-vibration structures are mostly optimized for vibrations in a single direction or at a specific frequency. For multi-dimensional composite vibrations commonly encountered in vehicle operation, such as longitudinal bumps, lateral tilts, and vertical impacts, the buffering is not targeted enough, and the vibration energy is difficult to attenuate sufficiently. Long-term use may lead to the positioning of the light source shift, affecting the lighting accuracy. In addition, in some structures, the sealing and anti-vibration functions are relatively independent, making it difficult to balance the protective effect and the buffering performance. Therefore, we propose a high-transmittance vehicle lamp module with high anti-vibration and vibration resistance. Summary of the Invention

[0005] This invention provides a high-transmittance automotive lamp module with high shock resistance and vibration damping. It achieves omnidirectional multi-dimensional vibration buffering and integrated sealing protection through the coordinated action of dual shock-resistant mechanisms, thereby increasing the shock resistance and vibration damping of the automotive lamp module.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-transmittance vehicle light module with high shock resistance and vibration damping includes a lamp housing, a bulb compartment installed at the left end of the lamp housing, a high beam lamp and a second shock resistance mechanism; The first anti-vibration mechanism includes a round rod, a U-shaped groove, an anti-vibration frame, round hole grooves, and micro-holes. An anti-vibration plate is provided in the middle of the high and low beam lamps. The anti-vibration frame is uniformly rotatably connected to the rear side edge of the anti-vibration plate. The round hole grooves are respectively opened on the side of the anti-vibration frame away from the center of the high and low beam lamps. The inside of the round hole grooves is filled with hydraulic oil. The inside of the anti-vibration frame is provided with a U-shaped groove. The inner wall of the round hole grooves near the U-shaped grooves is provided with uniformly distributed micro-holes. The micro-holes are all connected to the U-shaped grooves located inside the same anti-vibration frame. A piston is slidably connected inside the round hole grooves. A round rod is fixedly connected to the middle of the piston. The round rod is installed in conjunction with the bulb housing. The second anti-vibration mechanism is located at the front end of the bulb compartment and on the outer surface of the lamp housing. The second anti-vibration mechanism works in conjunction with the high and low beam lamps. Through the synergy of the two anti-vibration mechanisms, omnidirectional multi-dimensional vibration buffering and integrated sealing protection are achieved, increasing the vibration resistance and shock absorption of the vehicle lamp module.

[0007] Furthermore, the first anti-vibration mechanism also includes a mounting frame, a slide rail, and a slide block. The mounting frame is fixedly connected to the inside of the bulb compartment. The front, rear, left, and right side walls of the mounting frame are provided with mounting grooves, and slide rails are installed inside the mounting grooves. The slide blocks are rotatably connected to the ends of the round rod away from the center of the high and low beam lamps. The slide blocks are slidably connected to the radially adjacent slide rails. The cooperation of the mounting frame, slide rails, and slide blocks provides stable sliding guidance for the round rod, restricts the lamp body to only a slight displacement along a preset direction, avoids torsional offset caused by vibration, and ensures the accuracy of the optical path.

[0008] Furthermore, a lamp holder is threadedly connected to the rear side wall of the bulb compartment, and the high and low beam lamps are installed inside the lamp holder. The threaded connection between the lamp holder and the bulb compartment facilitates the installation and removal of the high and low beam lamps while establishing a circuit channel to ensure the reliable realization of the lamp start / stop and dimming functions.

[0009] Furthermore, the second anti-vibration mechanism includes rubber rings and corrugated plates. The rubber rings are fixedly connected to the inner wall of the opening on the front side wall of the bulb housing and the outer arc surface of the front end of the lamp housing, respectively. The interior of the rubber rings is filled with hydraulic oil. The corrugated plates are installed inside the rubber rings. The outer arc surface of the front end of the high and low beam lamps is located inside the opening and contacts the inner wall of the adjacent rubber rings. The rubber rings filled with hydraulic oil, combined with the built-in corrugated plates, can absorb external vibrations at the front end and enhance buffering toughness, as well as seal the opening of the bulb housing to prevent water vapor and dust from entering, thus achieving integrated anti-vibration and protection.

[0010] Furthermore, a reset plate is fixedly connected to the middle of the outer arc surface of the round rod, and a replacement plate is threadedly connected to the rear end of the reset plate. A guide post is slidably connected inside the replacement plate. The side of the guide post near the center of the high and low beam lamps is fixedly connected to the side of the anti-vibration frame away from the center of the high and low beam lamps. A spring is provided between the replacement plate and the radially adjacent anti-vibration frame. The spring is sleeved on the outer arc surface of the adjacent guide post. The spring and the guide post ensure that the lamp body quickly and accurately resets after vibration. The threaded replacement plate can be easily disassembled and replaced with vulnerable parts, reducing maintenance costs and difficulty.

[0011] Furthermore, a heat dissipation groove is provided at the upper end of the lamp housing, which is connected to the bulb compartment. Heat dissipation fins are provided at the rear end of the high and low beam lamps. The heat dissipation fins at the rear end of the high and low beam lamps increase the heat dissipation area and, together with the heat dissipation groove at the upper end of the lamp housing, form air convection, accelerate the dissipation of heat in the bulb compartment, and maintain a stable operating temperature of the lamp body.

[0012] Furthermore, it also includes a heat dissipation mechanism, which includes a suction shroud and a pipe. The pipe is fixedly connected to the right side wall of the bulb compartment, and the right end of the pipe is installed in conjunction with the flow channel on the rear side wall of the bulb housing. The suction shroud is fixedly connected to the left side of the pipe and located on the right side of the heat dissipation fins. The suction shroud is precisely aligned with the heat dissipation fins and provides a directional outlet channel for hot air through the pipe, efficiently extracting heat from the bulb compartment and improving the targeting and efficiency of heat dissipation.

[0013] Furthermore, the heat dissipation mechanism also includes a Venturi tube heat sink, which is disposed on the right end of the lower side wall of the lamp housing. The right end of the pipe is fixedly connected to the branch port in the middle of the Venturi tube heat sink, and the rear end of the Venturi tube heat sink is fixedly connected to the flow channel on the rear side wall of the lamp housing. The Venturi tube heat sink uses the fluid dynamics effect to generate negative pressure, which enhances the suction force of hot air in the bulb compartment, thereby achieving passive and efficient heat dissipation without additional power consumption.

[0014] Furthermore, rubber sheets are installed between the inner wall of the circular groove and the outer arc surface of the circular rod located inside it. The rubber sheets between the inner wall of the circular groove and the circular rod can not only reliably seal the hydraulic oil to prevent leakage, but also buffer the radial minor vibrations, thereby improving the sealing performance and shock resistance of the mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The high-transmittance vehicle lamp module with high shock resistance and vibration reduction disclosed in this invention has a first shock-resistant mechanism that uses a coordinated design of hydraulic damping, elastic reset, and guide limit. Its evenly distributed shock-resistant frame, combined with the hydraulic oil and microporous structure in the circular groove, can convert low-frequency large-amplitude vibrations into the flow friction energy of hydraulic oil. This effectively reduces the impact of strong vibrations such as off-road impacts and road bumps on the high and low beam lamps, ensuring lighting stability, greatly improving the service life and maintenance convenience of the mechanism, and adapting to the harsh working conditions of long-term high-frequency vibration.

[0016] 2. The high-transmittance vehicle lamp module with high shock resistance and vibration damping disclosed in this invention achieves multi-directional shock resistance through a multi-position layout of the first shock-resistant mechanism, realizing the weakening of complex vibrations without dead angles. Multiple shock-resistant frames evenly distributed on the edge of the shock-resistant plate form a ring protection, which can simultaneously respond to vibration impacts in different directions such as left and right, up and down. Whether the vehicle encounters longitudinal bumps, lateral tilts or vertical impacts during driving, the corresponding shock-resistant frames can be triggered and buffered simultaneously, avoiding overload of a single shock-resistant point and forming a multi-point shock resistance effect with multi-position response. This solves the problem that traditional single shock-resistant structures cannot cope with complex multi-dimensional vibrations, and greatly improves the structural stability of the lamp body under harsh road conditions.

[0017] 3. The high-vibration-resistant and high-transmittance automotive lamp module disclosed in this invention features a second anti-vibration mechanism with a rubber ring filled with hydraulic oil and an internal corrugated plate as its core. This mechanism forms an external vibration protection barrier for the module. It can quickly absorb external impact energy through the elastic deformation of the rubber ring and the fluidity of the hydraulic oil, weakening the impact of high-frequency, small-amplitude vibrations on the front end of the lamp body. The corrugated plate can also enhance the structural strength and buffering toughness of the rubber ring, preventing excessive deformation. At the same time, the close contact between the rubber ring and the lamp body and lamp housing forms a reliable sealing structure, effectively preventing moisture and dust from entering the bulb compartment. This achieves an integrated function of vibration resistance and protection. As a pre-buffer of the first anti-vibration mechanism, this mechanism, together with the internal damping system, forms a dual anti-vibration system of external interception and internal attenuation, significantly reducing the intensity of vibration transmitted to the core light source components and further improving the overall vibration resistance and environmental adaptability of the automotive lamp module.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 This embodiment provides a high-transmittance vehicle lamp module with high shock resistance and vibration damping, including lamp housing 1, a first shock-resistant mechanism and a second shock-resistant mechanism.

[0022] The front end of the lamp housing 1 is provided with a high-transparency lamp cover, which is an optical-grade polycarbonate high-transparency lamp cover. The left end of the interior of the lamp housing 1 is equipped with a bulb compartment 13, and the bulb compartment 13 is equipped with high and low beam lamps 10.

[0023] The first anti-seismic mechanism includes a mounting frame 21, a slide rail 22, a slide block 23, a round rod 24, a U-shaped groove 25, an anti-seismic frame 26, round hole grooves 27, and micro-holes 28. An anti-seismic plate 12 is located in the center of the high and low beam lamps 10. The anti-seismic frame 26 is rotatably connected to the rear edge of the anti-seismic plate 12. The round hole grooves 27 are respectively opened on the sides of the anti-seismic frame 26 away from the center of the high and low beam lamps 10. The interior of each round hole groove 27 is filled with hydraulic oil. The interior of each anti-seismic frame 26 is equipped with... The U-shaped groove 25 and the circular hole groove 27 are provided with uniformly distributed micro-holes 28 on their inner walls near the U-shaped groove 25. The micro-holes 28 are all connected to the U-shaped groove 25 located inside the same seismic frame 26. The inside of the circular hole groove 27 is slidably connected to a piston 16. The middle of the piston 16 is fixedly connected to a round rod 24. A rubber sheet 14 is installed between the inner wall of the circular hole groove 27 and the outer arc surface of the round rod 24 located inside it. The round rod 24 is installed in conjunction with the bulb compartment 13. Mounting bracket 21 is fixedly connected to the inside of bulb compartment 13. Mounting slots are provided on the front, back, left, and right side walls of mounting bracket 21. Slide rails 22 are installed inside each mounting slot. Slide seats 23 are rotatably connected to the ends of round rods 24 away from the center of high and low beam lamps 10. Slide seats 23 are slidably connected to the radially adjacent slide rails 22. The remaining vibration that is not buffered is transmitted to the anti-vibration plate 12 in the middle of high and low beam lamps 10, triggering multi-directional damping buffer. The anti-vibration brackets 26 on the edge of the anti-vibration plate 12 swing synchronously with the vibration, driving the piston 16 in the circular slot 27 to move along the circular slot. The rod 24 slides, squeezing the hydraulic oil in the circular groove 27 into the U-shaped groove 25 through the evenly distributed micro-holes 28. When the hydraulic oil flows in the micro-holes, it generates frictional damping, converting vibration energy into heat energy and achieving attenuation of low-frequency large-amplitude vibration. The slide block 23 at the end of the circular rod 24 slides along the slide rail 22 of the mounting bracket 21 to guide the vibration, prevent the lamp body from twisting or shifting, and ensure the stability of the light path. The rubber sheet 14 between the inner wall of the circular groove 27 and the circular rod 24 not only seals the hydraulic oil to prevent leakage, but also further buffers the radial minor vibration.

[0024] A reset plate 5 is fixedly connected to the middle of the outer arc surface of the round rod 24. A replacement plate 6 is threaded to the rear end of the reset plate 5. A guide post 7 is slidably connected inside the replacement plate 6. The side of the guide post 7 near the center of the high beam and low beam lamp 10 is fixedly connected to the side of the anti-vibration frame 26 away from the center of the high beam and low beam lamp 10. A spring 8 is provided between the replacement plate 6 and the radially adjacent anti-vibration frame 26. The spring 8 is sleeved on the outer arc surface of the adjacent guide post 7. If the spring 8 shows signs of aging after long-term use, unscrew the lamp holder 9, then unscrew the replacement plate 6 in sequence to maintain or replace the spring 8. After that, put on the new spring 8, install the replacement plate 6 and the lamp holder 9 in place. After the vibration is reduced, the spring 8 sleeved on the outer arc surface of the guide post 7 releases elastic potential energy, pushing the replacement plate 6 and the reset plate 5 to reset, driving the round rod 24 and the piston 16 back to the initial position. At the same time, the guide post 7 restricts the deformation direction of the spring 8 to prevent the lamp body from shifting during the reset process.

[0025] The rear side wall of the bulb compartment 13 is threaded with a lamp holder 9, and the high and low beam lamps 10 are installed inside the lamp holder 9.

[0026] The second anti-vibration mechanism is respectively installed at the front end of the bulb compartment 13 and on the outer surface of the lamp housing 1. The second anti-vibration mechanism works in conjunction with the high and low beam lamps 10. The second anti-vibration mechanism includes a rubber ring 31 and a corrugated plate 32. The rubber ring 31 is fixedly connected to the inner wall of the opening on the front side wall of the bulb compartment 13 and the outer arc surface of the front end of the lamp housing 1. The interior of the rubber ring 31 is filled with hydraulic oil. The corrugated plate 32 is installed inside the rubber ring 31. The outer arc surface of the front end of the high and low beam lamps 10 is located inside the opening and contacts the inner wall of the adjacent rubber ring 31. When the vehicle... When the vehicle vibrates or is subjected to external impact, the vibration is first transmitted to the rubber ring 31 at the front end of the lamp housing 1 and the opening of the bulb compartment 13. The hydraulic oil filled inside the rubber ring 31 absorbs part of the impact energy through its fluidity. In conjunction with the elastic deformation of the built-in wave plate 32, it buffers the radial and axial vibration impact forces. The rubber ring 31 is in close contact with the outer arc surface at the front end of the high and low beam lamps 10, which not only avoids hard contact between the lamp body and the housing, but also weakens the high-frequency small-amplitude vibration through the damping effect of the hydraulic oil. At the same time, it plays a sealing and protective role to prevent water vapor and dust from entering.

[0027] The upper end of the lamp housing 1 is provided with a heat dissipation groove 15, which is connected to the bulb compartment 13. The rear end of the high and low beam lamps 10 is provided with heat dissipation fins 11, and the inside of the heat dissipation groove 15 is provided with a filter screen.

[0028] The system also includes a heat dissipation mechanism, comprising a suction shroud 41 and a pipe 42. The pipe 42 is fixedly connected to the right side wall of the bulb compartment 13, and its right end is fitted with the flow channel on the rear side wall of the bulb housing 1. The suction shroud 41 is fixedly connected to the left side of the pipe 42 and located on the right side of the heat dissipation fins 11. The heat dissipation mechanism also includes a Venturi tube heat sink 43, which is located on the right end of the lower side wall of the bulb housing 1. The right end of the pipe 42 is fixedly connected to the branch port in the middle of the Venturi tube heat sink 43. The rear end of the Venturi tube heat sink 43 is fixedly connected to the flow channel on the rear side wall of the bulb housing 1. The front end of the Venturi tube heat sink 43 is an air inlet shroud, which is installed inside the mounting port on the bottom wall of the bulb housing 1. External air can enter the interior of the Venturi tube heat sink 43 through the air inlet shroud. The rear end of the Venturi tube heat sink 43 is an exhaust shroud, which is fixedly connected to the flow channel. Air enters the Venturi tube heat sink 43 through the air inlet shroud. The air inside the Venturi tube heat sink 43 can be discharged from the lower end of the exhaust hood. The diameter of the middle part of the Venturi tube heat sink 43 is smaller than the size of the air inlet hood and the exhaust hood. Both the air inlet hood and the exhaust hood are equipped with filters. When the headlights are working, the heat generated by the high and low beam lamps 10 is dissipated into the bulb compartment 13 through the heat dissipation fins 11 at the rear end. At the same time, when the vehicle is moving, the external airflow enters the inside of the hood through the air inlet hood at the front end of the Venturi tube heat sink 43. Since the diameter of the middle part of the Venturi tube is smaller than that of the air inlet hood and the exhaust hood, the airflow speed is increased, and a negative pressure is generated at the middle branch. The negative pressure forms a suction force through the pipe 42 and the suction hood 41 facing the right side of the heat dissipation fins 11, which draws out the hot air in the bulb compartment 13. The hot air is discharged from the module through the pipe and the flow channel of the rear side wall of the lamp housing 1. At the same time, the heat sink 15 realizes air convection and helps to discharge the waste heat.

[0029] The lamp housing 1 adopts a standardized installation method of positioning reference + bolt fastening + sealing protection, adapting to the conventional structure of automotive headlight mounting positions. Specifically, the rear end of the lamp housing 1 has three circumferentially evenly distributed positioning pins that precisely engage with the positioning holes of the vehicle mounting bracket. The positioning pins and the lamp housing 1 are integrally injection molded to ensure the X / Y / Z axis position accuracy of the lamp housing during installation, avoiding installation misalignment that could lead to abnormal light illumination angles. The outer side of the lamp housing 1 has a mounting reference surface that fits against the front bulkhead of the vehicle, ensuring that the lamp housing is flush with the vehicle's exterior after installation, without any gaps or deviations. The lamp housing 1 has 3-4 circumferentially designed bolt mounting ears corresponding to the vehicle mounting brackets. The threaded hole is used to connect the bolt through the mounting lug to the vehicle body bracket, ensuring a firm connection and preventing loosening due to long-term vibration. Anti-loosening washers are added to the bolt mounting lugs to further prevent bolt loosening caused by vibration during vehicle operation, improving installation reliability. After the bolt is tightened in place, the rubber ring 31 maintains a tight fit with the vehicle body reference surface under the action of clamping force. At the same time, due to its own elastic deformation, it generates reverse pressure to ensure that there is no gap between the lamp housing 1 and the vehicle body. The cable outlet hole at the rear end of the lamp housing 1 is equipped with a waterproof connector for the lamp holder 9 cable to pass through. After the cable passes through the connector, it is fixed by tightening the nut, which not only ensures the stability of the electrical connection, but also enhances the sealing performance.

[0030] The high-transmittance automotive light module with high shock resistance and vibration damping provided by this invention has the following vibration resistance principle: When the vehicle vibrates or is subjected to external impact, the vibration is first transmitted to the rubber ring 31 at the front end of the lamp housing 1 and the opening of the bulb compartment 13. The hydraulic oil filled inside the rubber ring 31 absorbs part of the impact energy through its fluidity. Combined with the elastic deformation of the built-in wave plate 32, it buffers the radial and axial vibration impact forces. The rubber ring 31 is in close contact with the outer arc surface of the front end of the high and low beam lamps 10, which not only avoids hard contact between the lamp body and the housing, but also weakens the high-frequency small-amplitude vibration through the damping effect of the hydraulic oil. At the same time, it plays a sealing and protective role, preventing water vapor and dust from entering. The remaining vibration that is not buffered is transmitted to the shock-absorbing plate 12 in the middle of the high and low beam lamps 10, triggering multi-directional damping buffering. The shock-absorbing frame 26 on the edge of the shock-absorbing plate 12 swings synchronously with the vibration, driving the piston 16 in the circular groove 27 along the... The round rod 24 slides, squeezing the hydraulic oil in the circular groove 27 into the U-shaped groove 25 through the evenly distributed micro-holes 28. The hydraulic oil generates frictional damping as it flows through the micro-holes, converting vibration energy into heat energy and attenuating low-frequency, high-amplitude vibrations. The slide block 23 at the end of the round rod 24 slides along the slide rail 22 of the mounting bracket 21, providing guidance for vibration and preventing the lamp body from twisting or shifting, ensuring a stable optical path. The rubber sheet 14 between the inner wall of the circular groove 27 and the round rod 24 seals the hydraulic oil to prevent leakage and further buffers radial minor vibrations. After the vibration weakens, the spring 8, sleeved on the outer arc surface of the guide post 7, releases elastic potential energy, pushing the replacement plate 6 and reset plate 5 to reset, driving the round rod 24 and piston 16 back to their initial positions. Simultaneously, the guide post 7 restricts the spring 8's shape. The direction is changed to avoid lamp body displacement during the reset process, ensuring that the high and low beam lamps 10 quickly return to their initial optical positions and the optical path deviation is controlled to a minimum. The high and low beam lamps 10 are installed inside the lamp holder 9 and are controlled by the vehicle controller to switch on or off. When the headlights are working, the front end of the lamp housing 1 is equipped with a high-transmittance lamp cover to ensure the light transmittance of the high and low beam lamps 10. The heat generated by the high and low beam lamps 10 is dissipated into the bulb compartment 13 through the heat dissipation fins 11 at the rear end. At the same time, when the vehicle is moving, the external airflow enters the shroud through the air intake shroud at the front end of the Venturi tube heat dissipation shroud 43. Since the diameter of the middle part of the Venturi tube is smaller than that of the air intake and exhaust shrouds, the airflow speed is accelerated, and a negative pressure is generated at the middle branch. The negative pressure is transmitted through the pipe 42 and the suction shroud 41 to the right side of the heat dissipation fins 11. The suction force draws out the hot air from the bulb compartment 13. The hot air flows through the pipe and the flow channel on the rear side wall of the bulb housing 1, and is discharged from the module through the exhaust hood. At the same time, the heat dissipation slot 15 realizes air convection to help dissipate residual heat. The complete air path is as follows: external cold air → ventilation opening of the grille / front panel below the bumper of the vehicle → mounting port on the bottom wall of the bulb housing 1 → air inlet of the Venturi tube heat dissipation hood 43 → negative pressure is generated at the middle branch of the Venturi tube heat dissipation hood 43 to draw the hot air from the bulb compartment 13 through the pipe 42 and the suction hood 41 → mixed hot air → exhaust hood of the Venturi tube heat dissipation hood 43 → flow channel on the rear side wall of the bulb housing 1 → exhaust opening / rear channel of the rear panel of the vehicle / bumper → outside the vehicle. The bulb housing 1 adopts a standardized installation method of positioning reference + bolt fastening + sealing protection.The standard structure for automotive headlight mounting positions is as follows: The rear end of the lamp housing 1 has three circumferentially evenly distributed locating pins that precisely engage with the locating holes on the vehicle mounting bracket. The locating pins and lamp housing 1 are integrally injection molded to ensure the X / Y / Z axis positional accuracy of the lamp housing during installation, preventing installation misalignment that could lead to abnormal light illumination angles. The outer side of the lamp housing 1 has a mounting reference surface that fits snugly against the front bulkhead of the vehicle, ensuring that the lamp housing is flush with the vehicle's exterior after installation, without any gaps or deviations. The lamp housing 1 has 3-4 circumferentially designed bolt mounting ears corresponding to the threaded holes on the vehicle mounting bracket. Bolts penetrate the mounting ears and... The vehicle body bracket features a threaded connection to ensure a secure fit and prevent loosening due to long-term vibration. Anti-loosening washers are added to the bolt mounting lugs to further prevent bolt loosening caused by vibration during vehicle operation, improving installation reliability. After the bolts are tightened, the rubber ring 31 maintains a tight fit with the vehicle body reference surface under the clamping force. Simultaneously, its own elastic deformation generates reverse pressure, ensuring no gap between the lamp housing 1 and the vehicle body. The wiring hole at the rear of the lamp housing 1 allows the lamp holder 9 cable to pass through, equipped with a waterproof connector. After the cable passes through the connector, it is secured with a clamping nut, ensuring both stable electrical connection and enhanced sealing performance.
