Description

Technical Field

[0001] This invention relates to the field of vehicle lighting technology, and more specifically to a foldable high color rendering LED lighting lamp suitable for vehicle scenarios. Background Technology

[0002] When vehicles are in the field, construction site, night rescue, or other work scenarios, the field of vision may be poor due to environmental factors. Therefore, a foldable structure is needed for easy onboard storage and flexible adjustment of the lighting angle to adapt to work, emergency and other scenarios. High color rendering performance restores the true colors of objects, ensuring that maintenance details are clearly visible. It takes into account portability, practicality and lighting accuracy to meet the core needs of car owners for professional exterior lighting.

[0003] Referencing patent CN117053165A, the core concept is a highly efficient heat conduction system that transfers the heat generated by the LED lights to the skin-friendly fabric, providing warmth and comfort. Simultaneously, it features adjustable clamps and a restraint system to adapt to different usage scenarios and meet both lighting and emergency needs. Furthermore, the top cone design enhances escape functionality through broken windows, resulting in an overall innovative solution that is energy-saving, environmentally friendly, and multifunctional.

[0004] Currently, the main solution for external lighting needs in vehicle scenarios is to use simple articulated manual adjustable vehicle lighting fixtures. This approach has many inconveniences. Most existing adjustable vehicle lighting devices are manually articulated, resulting in low adjustment precision. After adjustment, there is no reliable locking and limiting structure. Bumps and vibrations during vehicle operation can easily cause unexpected deviations in the illumination angle. In addition, there is a lack of comprehensive dustproof, waterproof, drainage, and debris removal protection designs. The internal transmission structure and lamp body are easily corroded by the external environment, resulting in poor operational reliability and difficulty in adapting to the complex outdoor driving environment of vehicles.

[0005] Therefore, it is necessary to improve the vehicle lighting device by designing a system that features fully enclosed protection for foldable storage, precise multi-dimensional electric adjustment, a dedicated and stable installation structure adapted to vehicle scenarios, and a comprehensive dustproof, waterproof, and drainage protection system. This system should also incorporate high color rendering LED lighting components. In the folded state, the device should achieve fully enclosed protection for the lamp body and transmission structure, extending its lifespan. In operation, it should be electrically adjustable for precise horizontal orientation and multi-dimensional tilt angles, adapting to all vehicle lighting needs. Furthermore, a dedicated clamping installation structure and multiple locking and limiting mechanisms should ensure installation stability and lighting accuracy during vehicle movement, balancing professional lighting effects, operational reliability, environmental adaptability, and safety. To address these issues, we offer a foldable high color rendering LED lighting device suitable for vehicle scenarios. Summary of the Invention

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] Example 1: As Figure 1-8 As shown, the present invention provides a foldable high color rendering LED lighting suitable for vehicle scenarios. The top surface of the roof rack 1 is provided with a mounting bracket unit 3 that can ensure the stability of the equipment during vehicle operation. The outer surface of the mounting bracket unit 3 is provided with a lighting unit 2 that can be folded and stored and has multi-dimensional adjustable illumination angle. The lighting unit 2 includes a mounting base 21 provided on the outer surface of the fixed bracket 34, an outer shell 22 provided on the top surface of the mounting base 21 that can adjust the orientation of the equipment and plays a protective and storage role, and a bracket 23 provided inside the outer shell 22 for providing multi-angle lighting operation.

[0035] The main body of the lighting lamp 25 is a high color rendering LED lighting component. The bracket 23 is fixedly connected to the storage cover plate 24, and a gap is reserved between the two for the threaded rod 28 to pass through. One end of the angle adjustment bracket 26 is limited by the threaded adjustment block 27 and the threaded rod 28, so that one end of the angle adjustment bracket 26 can only slide linearly along the internal cavity of the protective base 29. The angle adjustment bracket 26 and the lighting lamp 25 are hinged by a pivot. The pivot connecting the lighting lamp 25 and the angle adjustment bracket 26 is adapted to the size of the storage slot 211 and can be stored in the storage slot 211. One end of the lighting lamp 25 is limited by the bracket 23 and can only rotate around the pivot connecting it to the bracket 23.

[0036] The internal structure of the bracket 23 is fixedly connected to a storage guard plate 24. A certain gap is reserved between the storage guard plate 24 and the bracket 23. A storage slot 211 is provided on the side of the storage guard plate 24. A light 25 is movably connected inside the storage guard plate 24. One end of the outer surface of the light 25 is movably connected inside the storage slot 211.

[0037] The bracket 23 has movable shafts 212 fixedly connected to both sides, and angle adjustment half gear 210 fixedly connected to the back of the bracket 23. The bottom surface of the bracket 23 is fixedly connected to a protective base 29. The side of the lighting lamp 25 is movably connected to an angle adjustment bracket 26. The bottom of the outer surface of the angle adjustment bracket 26 is rotatably connected to a threaded adjustment block 27. The protective base 29 has a threaded rod 28 inside, and the threaded adjustment block 27 is threadedly connected to the outer surface of the protective base 29.

[0038] The movable shaft 212 fixedly connected to the side of the bracket 23 is used to hinge with the arm 221. The angle adjustment half gear 210 set on the back of the bracket 23 meshes with the adjustment gear 222 to drive the bracket 23 to a maximum rotation angle of 90° under the drive of the adjustment gear 222. The bottom surface of the protective base 29 can play a protective role when the equipment is stored or when it is in operation. The back of the protective base 29 is provided with a first power component consisting of a motor and a gearbox. The threaded rod 28 is fixedly installed on the output end of the first power component.

[0039] In this embodiment, when the device is in the storage state, the outer shell 22 and the protective base 29 are combined to form a complete closed cavity. The lighting lamp 25 stored inside the outer shell 22 can be isolated from dust and other impurities generated during vehicle operation. At the same time, the angle adjustment bracket 26 can pull the lighting lamp 25 to be stored inside the storage protective plate 24 to achieve protection and extend the service life of the lighting lamp 25.

[0040] When the equipment is in the unfolded state, the protective base 29 is located on top of the lighting lamp 25, which can protect the threaded rod 28, threaded adjustment block 27, motor and matching transmission structure inside, effectively isolate rainwater erosion and ensure the reliability of equipment operation.

[0041] The screw rod 28 can be rotated by a motor, which will drive the screw adjustment block 27 to make linear displacement, thereby adjusting the tilt angle of the angle adjustment bracket 26. The angle adjustment bracket 26 simultaneously drives the lighting lamp 25 to complete the pitch angle adjustment, so that the lighting lamp 25 is aligned with the target illumination angle. During vehicle movement, the angle adjustment bracket 26, the lighting lamp 25, the bracket 23 and other components together form a stable support system, ensuring the structural stability and illumination accuracy of the lighting lamp 25 in operation.

[0042] Example 2: As Figure 1-8As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the inner sides of the outer shell 22 are provided with sliding grooves 216, one end of the inner bottom surface of the outer shell 22 is provided with a drainage groove 213, the middle of the inner bottom surface of the outer shell 22 is provided with a threaded rod 214, the inner sliding groove 216 is slidably connected with a connecting rod 224, the side of the connecting rod 224 is rotatably connected with an auxiliary rotating wheel 217, the auxiliary rotating wheel 217 is slidably connected in the inner sliding groove 216, the side of the connecting rod 224 is fixedly connected with a movable base 215, the bottom surface of the movable base 215 is fixedly connected with an adjusting threaded block 218, and the adjusting threaded block 218 is threadedly connected to the outer surface of the threaded rod 214.

[0043] The sliding grooves 216 are respectively located on the left and right sides inside the outer shell 22; two sets of drainage grooves 213 are provided on the bottom surface inside the outer shell 22, the outlet of the drainage groove 213 is located at the bottom of the back of the outer shell 22, and a protective net is fixedly installed at the outlet; a second power assembly consisting of a motor and a gearbox is provided on the bottom surface of the outer shell 22, and one end of the threaded rod 214 is fixedly installed at the output end of the second power assembly;

[0044] One end of the outer shell 22 penetrates the top surface of the mounting base 21 and is fixedly connected to an orientation adjustment gear 227. A bidirectional limiting ratchet 225 is fixedly connected to the top surface of the orientation adjustment gear 227. A limiting spring rod 226 is fixedly installed inside the mounting base 21. The output end of the limiting spring rod 226 is movably connected to the side of the bidirectional limiting ratchet 225.

[0045] The bottom surface of the outer shell 22 is fixedly connected to the orientation adjustment gear 227, and is rotatably mounted inside the top cavity of the mounting base 21 via the orientation adjustment gear 227. A bidirectional limiting ratchet 225 is fixedly connected to the bottom surface of the orientation adjustment gear 227. The mounting base 21 is equipped with a motor gear transmission mechanism for driving the orientation adjustment gear 227 to rotate. At the same time, the limiting spring rod 226 installed inside the mounting base 21 can lock and fix the current orientation of the outer shell 22 by limiting the bidirectional limiting ratchet 225 to prevent reverse movement.

[0046] In this embodiment, when the device is in operation, the airflow generated by the vehicle's movement can enter the interior of the housing 22 and be discharged along the drainage channel 213. The airflow can simultaneously carry rainwater, dust and other impurities that have entered the cavity out, ensuring the relative cleanliness of the environment inside the housing 22.

[0047] The motor gear transmission mechanism inside the mounting base 21 can drive the orientation adjustment gear 227 to rotate, thereby adjusting the horizontal orientation of the lighting lamp 25. This allows the lighting light to be projected onto the target area without changing the vehicle's driving direction, ensuring the working field of vision in dark environments. During and after the orientation adjustment of the housing 22, the limiting spring rod 226 always remains engaged with the bidirectional limiting ratchet 225 to prevent the orientation of the housing 22 from deviating unexpectedly, thus ensuring the stability of the lighting positioning.

[0048] Example 3: As Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, an electric locking rod 220 is provided inside the movable base 215, a retaining arm 221 is rotatably connected to the side of the movable base 215, a movable shaft 212 is movably connected inside the retaining arm 221, one end of the retaining arm 221 passes through the side of the movable base 215 and is fixedly connected to a rotating gear 219, the output end of the electric locking rod 220 is engaged with the side of the rotating gear 219, an adjusting gear 222 is rotatably connected to the middle of the inside of the retaining arm 221, an angle adjusting half gear 210 and the adjusting gear 222 mesh with each other, and an electric locking rod 223 is fixedly connected inside the retaining arm 221, the electric locking rod 223 is engaged with the side of the adjusting gear 222;

[0049] Threaded rod 214 is disposed on the left and right sides of the movable base 215. An auxiliary rotating wheel 217 is rotatably mounted on the side of threaded rod 214. The auxiliary rotating wheel 217 is embedded in the slide groove 216 and can slide along the groove to assist the movable base 215 in making a smooth linear reciprocating motion. An adjusting threaded block 218 is fixedly connected to the bottom surface of the movable base 215. The adjusting threaded block 218 is slidably embedded in the internal cavity of the outer shell 22 and engages with the threaded outer surface of threaded rod 214. A third power assembly driven by a motor is provided inside the movable base 215. An electric locking rod 220 is used to lock and limit the rotating gear 219.

[0050] The arm 221 is hinged to the outer surface of the movable shaft 212. The arm 221 is equipped with a motor-driven adjusting gear 222. The bracket 23 can rotate around the movable shaft 212. The angle adjusting half gear 210 on the back of the bracket 23 is constantly meshed with the adjusting gear 222. The electric locking lever 223 can lock and limit the adjusting gear 222, thereby achieving rotational constraint on the angle adjusting half gear 210. The arm 221 and the rotating gear 219 are both rotatably mounted on the side of the movable base 215.

[0051] In this embodiment, the rotating threaded rod 214 can drive the movable base 215 to move linearly along the internal cavity of the outer shell 22 through the threaded transmission with the adjusting threaded block 218, thereby realizing the storage of the lighting lamp 25 inside the outer shell 22 or its extension to the outside. When the lighting lamp 25 is fully extended out of the outer shell 22, the third power component inside the movable base 215 drives the rotating gear 219 to rotate, adjusting the lighting lamp 25 to the target working angle. Then, the electric clamp rod 220 locks and limits the rotating gear 219 to ensure the structural stability of the lighting lamp 25 in the working state.

[0052] At this time, the motor inside the arm 221 drives the adjusting gear 222 to rotate. Through the meshing transmission with the angle adjusting half gear 210, the bracket 23 and the protective base 29 are adjusted to the target position. The lighting lamp 25 is fully extended and enters the lighting operation state. The multi-dimensional pitch angle adjustment of the lighting lamp 25 can be realized by adjusting the differential angle of the adjusting gear 222 and the rotating gear 219. Combined with the horizontal orientation adjustment of the outer shell 22, the full-area multi-angle lighting operation with the equipment as the axis is finally realized.

[0053] Example 4: Figure 1-8 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the mounting bracket unit 3 includes a clamping plate 35 movably connected to the surface of the roof rack 1 for fixing, and a fixed bracket 34 for supporting the lighting unit 2 disposed on the top surface of the clamping plate 35. A limiting rod 36 is fixedly connected to one end of the top surface of the clamping plate 35. The limiting rod 36 is slidably connected inside the fixed bracket 34. A threaded adjusting rod 37 is rotatably connected to the top surface of the clamping plate 35. The threaded adjusting rod 37 is threadedly connected inside the fixed bracket 34. A limiting nut 38 is threadedly connected to the outer surface of the threaded adjusting rod 37.

[0054] The mounting base 21 is fixedly installed on the middle of the outer surface of the fixed rod 31. The rod body of the adjusting rod 33 is evenly provided with multiple fixing holes. The bolt 32 can pass through the fixing holes of the adjusting rod 33 to lock the adjusting rod 33 and the fixed rod 31. The contact surface between the mounting base 21 and the roof is provided with a buffer and shock-absorbing pad.

[0055] The side of the fixed bracket 34 is fixedly connected to the adjusting rod 33, the outer surface of the adjusting rod 33 is slidably connected to the fixed rod 31, the top surface of the fixed rod 31 is threaded with the bolt 32, the bolt 32 is snapped into the inside of the adjusting rod 33, and the mounting base 21 is fixedly connected to the middle of the outer surface of the fixed rod 31.

[0056] A clamping plate 35 is installed at one end of the bottom surface of the fixed bracket 34. The clamping position of the clamping plate 35 can be adjusted by the threaded adjustment rod 37. The equipment can be fixedly installed on the roof rack or door frame gap through the clamping structure. The limit nut 38 is threaded to the outer surface of the threaded adjustment rod 37. The equipment can be locked and prevented from loosening by the pressing friction with the surface of the fixed bracket 34 and the use of thread adhesive, thus ensuring the stability of the equipment installation.

[0057] In this embodiment, during installation, the fitting length and installation angle of the fixing rod 31 and the adjusting rod 33 can be adjusted according to the target installation position. After adjustment, the adjusting rod 33 and the fixing rod 31 are locked and fixed by the bolt 32. At this time, the mounting base 21 is attached to the roof surface, and the clamping plate 35 is driven to move by the threaded adjusting rod 37, so that the clamping plate 35 is firmly clamped to the roof rack or door frame until the lighting unit is completely locked and stable. Finally, the limiting nut 38 is tightened in the opposite direction. The clamping friction between the limiting nut 38 and the fixing bracket 34, combined with the threaded adhesive, realizes the anti-loosening limit of the equipment and ensures the installation stability of the equipment throughout the operation process.

[0058] The working principle of this foldable high color rendering LED lighting fixture, suitable for automotive applications, will be explained in detail below.

[0059] like Figure 1-8 As shown, when the device is in the storage state, the outer shell 22 and the protective base 29 combine to form a complete enclosed cavity, protecting the lamp 25 stored inside and isolating it from dust and other impurities during vehicle operation. Simultaneously, the angle adjustment bracket 26 can pull the lamp 25 into the storage cover 24, extending the lamp's lifespan.

[0060] After the equipment is deployed, the protective base 29 is located on top of the lighting lamp 25, protecting the internal threaded rod 28, threaded adjustment block 27, and motor transmission structure from rainwater corrosion and ensuring the reliability of the equipment's operation. The motor drives the threaded rod 28 to rotate, causing the threaded adjustment block 27 to move linearly, thereby adjusting the tilt angle of the angle adjustment bracket 26, completing the pitch angle adjustment of the lighting lamp 25, ensuring that the lighting lamp is aimed at the target area and provides precise illumination;

[0061] In operation, the airflow generated by the vehicle's movement can enter the interior of the housing 22 and be discharged along the drainage channel 213, carrying away rainwater, dust, and other impurities, keeping the interior environment clean. The motor gear transmission mechanism inside the mounting base 21 can drive the orientation adjustment gear 227 to rotate, adjusting the horizontal orientation of the lighting lamp 25, accurately projecting the lighting beam onto the target area without changing the vehicle's direction of travel, ensuring visibility in dark environments.

[0062] The rotating threaded rod 214, through threaded transmission with the adjusting threaded block 218, drives the movable base 215 to move linearly along the internal cavity of the outer casing 22, thereby extending or retracting the lighting lamp 25. When the lighting lamp is fully extended from the casing, the third power component inside the movable base 215 drives the rotating gear 219 to rotate, adjusting the lighting lamp to the target working angle. The electric locking rod 220 locks the rotating gear 219 to ensure the stability of the equipment in operation.

[0063] The adjusting gear 222 inside the motor-driven arm 221 meshes with the angle adjusting half gear 210, driving the bracket 23 and protective base 29 to adjust to the target position. The lighting lamp 25 is fully extended and enters the lighting operation state. Through the differentiated angle adjustment of the adjusting gear 222 and the rotating gear 219, the lighting lamp can achieve multi-dimensional pitch angle adjustment, and cooperate with the horizontal orientation adjustment of the housing 22 to ultimately achieve full-area multi-angle lighting;

[0064] During installation, the length and angle of the fixing rod 31 and the adjusting rod 33 are adjusted according to the target installation position, and the adjusting rod and the fixing rod are locked together by bolts 32. The mounting base 21 fits tightly against the roof surface, and then the clamping plate 35 is moved by the threaded adjusting rod 37, firmly clamping it to the roof rack or door frame until the lighting unit is completely locked. Finally, the limiting nut 38 is tightened. The clamping friction between the limiting nut and the fixing bracket 34, combined with the thread sealant, prevents the equipment from loosening and ensures the installation stability during the operation.

[0065] In summary, this paper describes a lighting structure with multiple protective and adjustable functions in three states: storage, deployment, and operation. Its outer shell and protective base combine to form a sealed cavity, protecting the lamp from dust and impurities. The electric adjustment system allows for multi-dimensional tilt and horizontal angle adjustments, ensuring precise illumination. A drainage design effectively removes internal impurities, keeping the equipment clean. Simultaneously, a robust installation mechanism, through an adjustment rod and locking device, ensures the stability of the equipment during vehicle movement. This design combines efficient lighting, durability, precise adjustment, and safe installation, providing a reliable solution for vehicle lighting.

[0066] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the scope of protection of the present invention.
