Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically a compact LED floodlight for automobiles. Background Technology

[0002] Automotive lighting systems are key components for ensuring driving safety. With the development of automotive technology and the diversification of user needs, traditional halogen lamps and xenon lamps have been gradually replaced by LED headlights due to their disadvantages such as high energy consumption, short lifespan, and slow response speed. LED light sources have the advantages of high brightness, low energy consumption, long lifespan, and fast response. Especially in the field of floodlights, they can provide wide and uniform illumination for vehicles in scenarios such as reversing at night, field operations, and campground lighting.

[0003] The existing drawbacks are that during vehicle operation, especially on bumpy roads, during rapid acceleration or deceleration, continuous vibrations and impacts are generated. Traditional lamp installation structures are mostly rigid connections, which are difficult to effectively buffer and absorb these impact energies. This causes LED beads and their driving circuits to be under vibration stress for a long time, which can easily lead to loosening and detachment of lamp bead solder joints and damage to electronic components, significantly shortening the lifespan of the lamps and bringing light decay and safety risks. Moreover, traditional lamp structures are complex, bulky, and have limited functionality, making it impossible to flexibly switch lighting modes according to different scenarios such as daytime driving, urban night roads, and outdoor floodlighting, thus limiting the applicability of the lights and the user experience.

[0025] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 An embodiment of this utility model is provided: a compact LED floodlight for automobiles, wherein one end of the single-threaded rod 17 is a hexagonal screw head, and the other end of the single-threaded rod 17 is a threaded end. The threaded end of the single-threaded rod 17 passes through the first connecting hole 7 of the first connecting plate 6. The nut 20 is fitted onto the threaded end of the single-threaded rod 17. The inner shell 1 has an arc-shaped sidewall with a flared mouth 4. The inner sidewall of the flared mouth 4 is fitted with the outer sidewall of the LED lamp 13. The inner sidewall of the buckle 2 is fitted with the outer sidewall of the buckle block 22. The buckle block 22 is set at the top and bottom of the outer wall of the lamp cover 21. The arc-shaped sidewall of the lamp cover 21 is fitted with the arc-shaped sidewall of the inner shell 1 through a rubber ring.

[0026] Next, the operator first assembles the car light. First, the rubber ring is placed on the arc-shaped side wall of the inner shell 1. Then, the arc-shaped side wall of the lamp cover 21 is tightly attached to the rubber ring. The operator rotates the two buckles 2 at the top of the outer wall of the inner shell 1 downward so that the buckles 2 are tightly engaged with the clip 22. Then, the operator rotates the two buckles 2 at the bottom of the outer wall of the inner shell 1 upward so that the buckles 2 are tightly fixed with the clip 22. Then, the operator applies sealant to the gap between the lamp cover 21 and the inner shell 1 so that the lamp cover 21 is tightly attached and fixed to the inner shell 1 by the rubber ring.

[0027] The operator then aligns the buffer cylinder 8 with the protective cover 5. The buffer cylinder 8 is made of elastic rubber. The operator then pushes the buffer cylinder 8 into the protective cover 5, at which point the outer side of the buffer cylinder 8 and the inner side of the protective cover 5 are tightly fitted together. Next, the operator picks up the light adjuster 14 and aligns the lamp post 11 at the front end of the light adjuster 14 with the round hole 9 in the buffer cylinder 8, so that the side edges 12 on both sides of the outer wall of the lamp post 11 engage with the sliding grooves 10 in the round hole 9. The operator then pushes the light adjuster 14 into the buffer cylinder 8 until it reaches the bottom. At this point, the top of the outer wall of the buffer cylinder 8 is tightly fitted with the inner wall of the protective cover 5, and the bottom of the outer wall of the buffer cylinder 8 is tightly fitted with the top of the outer wall of the light adjuster 14. The second connecting hole 16 of the second connecting plate 15 is concentrically aligned with the first connecting hole 7 of the first connecting plate 6. Finally, the operator removes the first buffer sleeve 18 from... The threaded end of the single-threaded rod 17 is inserted, so that the bottom end of the outer wall of the first buffer sleeve 18 is in contact with the hexagonal threaded head of the single-threaded rod 17. Then, the single-threaded rod 17 is passed through the second connecting hole 16, so that the top end of the outer wall of the first buffer sleeve 18 is in contact with the bottom end of the outer wall of the second connecting plate 15. Then, the second buffer sleeve 19 is inserted from the threaded end of the single-threaded rod 17, so that the bottom end of the outer wall of the second buffer sleeve 19 is in contact with the top end of the outer wall of the second connecting plate 15. Both the second buffer sleeve 19 and the first buffer sleeve 18 are made of elastic rubber. Then, the single-threaded rod 17 is passed out along the first connecting hole 7. The threaded groove of the nut 20 is engaged with the threaded end of the single-threaded rod 17. The nut 20 is tightened. At this time, the LED light 13 is fixed in the lamp cover 21 through the horn 4. Finally, the bolt is passed through the screw hole in the fixing block 3 to install and fix the inner shell 1 on the car.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model provides: a compact LED floodlight for automobiles, wherein the inner side of the first buffer sleeve 18 is fitted with the smooth outer side of the single-threaded rod 17, the bottom end of the outer wall of the first buffer sleeve 18 is fitted with the hexagonal screw head of the single-threaded rod 17, the top end of the outer wall of the first buffer sleeve 18 is fitted with the bottom end of the outer wall of the second connecting plate 15, the inner side of the second buffer sleeve 19 is fitted with the smooth outer side of the single-threaded rod 17, one end of the second buffer sleeve 19 is fitted with the top end of the outer wall of the second connecting plate 15, and the other end of the second buffer sleeve 19 is fitted with the bottom end of the outer wall of the first connecting plate 6. The threaded end of the single-threaded rod 17 passes through the first connecting hole 7 of the first connecting plate 6, and the nut 20 is fitted on the threaded end of the single-threaded rod 17 to fix the first buffer sleeve 18 and the second buffer sleeve 19.

[0029] Furthermore, when the car is in a bumpy or accelerating state, since the fixing block 3 is fixed to the car, the forward inertial force is transmitted to the inner shell 1 through the fixing block 3. The rubber ring between the inner shell 1 and the lamp cover 21 buffers the inertial force. The rubber ring absorbs vibration through elastic deformation, transforming the rigid contact between the lamp cover 21 and the inner shell 1 into a flexible connection, reducing relative displacement and noise, and preventing the lamp cover 21 from loosening or breaking. At the same time, the rubber ring provides dust and water protection for the LED lamp 13 through a sealing connection. The inertial force is transmitted to the protective cover 5 through the inner shell 1. The buffer cylinder 8 in the protective cover 5 provides initial buffering of the inertial force. The buffer cylinder 8 is made of elastic rubber material. Through compression and rebound, it buffers part of the inertial force, converting high-frequency vibration into low-frequency motion, reducing the peak value of the inertial force, and protecting the structure of the internal lamp post 11. Then The remaining inertial force is transmitted to the first connecting plate 6 through the protective cover 5. The first connecting plate 6 and the second connecting plate 15 are flexibly connected by four second buffer sleeves 19. The inertial force is transmitted to the first buffer sleeve 18 and the second buffer sleeve 19 for buffering and dilution. The second buffer sleeve 19 provides flexible support and generates a small displacement through elastic deformation, avoiding stress concentration caused by rigid connection and extending the service life of the equipment. At the same time, the first buffer sleeve 18 on the single-threaded rod 17 also provides buffering. The two buffer sleeves work together to disperse the concentrated force through multi-stage buffering of elastic material, gradually consume the inertial force, reduce the impact of the inertial force on the light regulator 14, protect the electronic components inside the light regulator 14, improve the shock resistance and durability of the lamp, ensure stable operation under harsh road conditions, and extend the service life.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4An embodiment of this utility model is provided: a compact LED floodlight for automobiles, wherein a protective cover 5 is provided on the inner wall side of the inner shell 1, and a first connecting plate 6 is provided at the bottom of the outer wall of the protective cover 5. The inner wall side of the first connecting plate 6 is fitted with the outer wall side of the buffer cylinder 8. The buffer cylinder 8 is connected to the lamp post 11 through a round hole 9. A second connecting plate 15 is provided at the top of the outer wall of the light adjuster 14. The second connecting plate 15 is connected to the first connecting plate 6 through a single-threaded rod 17. A first buffer sleeve 18 and a second buffer sleeve 19 are provided on the outer wall side of the single-threaded rod 17.

[0031] Furthermore, when the car is in a bumpy or decelerating state, the fixing block 3 is installed on the car body. The inertial force generated at this time will be transmitted to the inner shell 1 through the fixing block 3. The rubber ring at the joint between the inner shell 1 and the lamp cover 21 buffers the inertial force. The rubber ring undergoes elastic deformation, eliminating the hard collision and friction between the inner shell 1 and the lamp cover 21, preventing abnormal noise caused by relative displacement of components or causing the lamp cover 21 to loosen and fail to seal. The inertial force is transmitted to the inner protective cover 5 through the inner shell 1. The protective cover 5 guides the impact force evenly to the buffer cylinder 8, avoiding stress concentration at a point. The buffer cylinder 8 performs initial buffering and attenuation of the transmitted inertial force. The buffer cylinder 8 consumes a large amount of impact energy through the compression and rebound characteristics of the elastic rubber material, transforming the violent instantaneous impact into a soft and low-frequency motion, significantly reducing the peak value of the impact force, and protecting the internal lamp post 11 and LED lamp 13 from direct damage. Then, after passing through The initial buffered inertial force is transmitted to the first connecting plate 6 through the protective cover 5. The first connecting plate 6 and the second connecting plate 15 are flexibly connected by four second buffer sleeves 19. The second buffer sleeves 19 provide elastic support between the connecting plates, so that the first connecting plate 6 and the second connecting plate 15 produce a small relative displacement when subjected to force, thereby avoiding fatigue damage or breakage caused by stress concentration at the rigid connection point, and greatly extending the service life of the connection structure. The first buffer sleeve 18 buffers the remaining impact force by compressing and rebounding the elastic rubber. The buffering effect of the first buffer sleeve 18 and the second buffer sleeve 19 can effectively cope with the complex inertial force generated by the bumps and acceleration and deceleration of the car during driving, fundamentally avoiding the problems of component damage, loose screws or electronic component failure caused by rigid connection, and significantly improving the durability, stability and service life of the lamp under harsh road conditions.

[0032] Please see Figure 1 and Figure 2The present invention provides an embodiment of a compact LED floodlight for automobiles, wherein a connecting wire 23 is provided at the bottom of the outer wall of the light adjuster 14, one end of the connecting wire 23 is connected to the car console, and the other end of the connecting wire 23 is connected to the processor inside the light adjuster 14. The processor is provided with four lighting modes, namely low beam mode, high beam mode, daytime running mode and floodlight mode. The processor is connected to the LED light 13 through a control wire embedded in the light pole 11.

[0033] Furthermore, when the car is driving during the day, the driver sends a signal to activate the daytime running mode through the car's control console. The signal is transmitted to the headlight regulator 14 through the connection line 23. After receiving the signal, the processor in the headlight regulator 14 activates the daytime running mode. The processor activates the LED lights 13 through the control line, so that the LED lights 13 emit light in a low-power mode, realizing low-energy daytime driving lighting, significantly improving the vehicle's visibility during the day, enhancing driving safety, and at the same time minimizing power consumption and extending LED life.

[0034] When the car is on a city road with high light intensity at night or when encountering another vehicle, the driver sends a signal to switch to low beam mode through the car's control panel. After receiving the signal, the processor of the headlight modulator 14 quickly activates the low beam mode. The processor activates the LED light 13 through the control line embedded in the light pole 11, providing sufficient illumination for the front of the vehicle at close range, while ensuring that the light does not shine directly on the driver or the rearview mirror of the vehicle in front, thus ensuring lighting etiquette and safety on public roads.

[0035] When visibility is low at night, the driver sends a signal to activate the high beam mode through the car's control panel. After receiving the signal, the processor of the headlight adjuster 14 activates the high beam mode. The processor activates the LED lights 13 through the control line embedded in the light pole 11, which significantly extends the lighting distance and widens the lighting area, allowing the driver to detect potential dangers in the distance earlier and providing more time for judgment and braking, thus greatly improving nighttime driving safety.

[0036] When a car needs to provide ambient lighting in low-light environments such as when reversing at night or in warehouses or campsites, the driver activates the floodlight mode via the car's control panel. The control panel sends a signal to the headlight adjuster 14 via the connecting wire 23 to activate the floodlight mode. Upon receiving the signal, the processor activates the high beam mode and then activates the LED light 13 via the control wire embedded in the light pole 11. The LED light 13 projects a wide, uniform, and non-glaring illumination area that clearly covers a large area on the side of the vehicle, improving visibility and safety when reversing or working in poor lighting conditions. This effectively avoids collisions or accidents caused by blind spots and significantly enhances the versatility and environmental adaptability of the LED light 13.

[0037] Working principle: The lamp cover 21 is sealed to the inner shell 1 by a rubber ring and locked by a buckle 2 to ensure dust and water resistance. When the car is driving on a bumpy road or experiencing acceleration and deceleration, the inertial force generated is first transmitted to the inner shell 1 through the fixing block 3. The rubber ring between the inner shell 1 and the lamp cover 21 undergoes elastic deformation to absorb the initial vibration and avoid rigid collision and abnormal noise. Then the impact force is transmitted through the inner shell 1 to the buffer cylinder 8 inside the protective cover 5. The buffer cylinder 8 is made of elastic rubber and further attenuates the impact energy through compression and rebound characteristics, converting high-frequency vibration into low-frequency motion, significantly reducing peak force, and protecting the internal lamp post 11 and LED lamp 13 from direct damage. The remaining inertial force is transmitted to the first buffer sleeve 18 and the second buffer sleeve 19 through the first connecting plate 6. The first buffer sleeve 18 and the second buffer sleeve 19 produce small displacements when subjected to force, dispersing stress, avoiding screw loosening or component fatigue, and effectively protecting the precision electronic components inside the light regulator 14.

[0038] The headlight modulator 14 receives commands from the car's control console via the connection cable 23. The processor in the headlight modulator 14 supports four modes: low beam, high beam, daytime running light, and floodlight. The driver can switch modes according to environmental needs. The daytime running light mode can operate with low power consumption and improve daytime visibility. The low beam mode can provide moderate illumination and avoid glare. The high beam mode can extend the illumination distance and width. The floodlight mode can achieve wide-area uniform illumination and is suitable for reversing or dark environments. The processor adjusts the LED lights 13 in real time via the control line embedded in the light pole 11 to ensure efficient, stable, and energy-saving lighting, significantly improving the light fixture's shock resistance, durability, and environmental adaptability under harsh road conditions.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
