Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, and specifically relates to a device for adjusting the angle of a lamp. Background Technology

[0002] In the field of lighting equipment applications, LED lamps have been widely adopted in home lighting, commercial lighting, industrial lighting, and off-road vehicle lighting due to their advantages such as low energy consumption, long lifespan, and high luminous efficiency. Different usage scenarios have significantly different requirements for the illumination angle of LED lamps. The operating environment of off-road vehicles is particularly unique, often involving complex road conditions such as mountains, deserts, and jungles. At night or in low-visibility environments, the illumination angle needs to be adjusted in real time according to road conditions—for example, when climbing a hill, the light needs to be adjusted upwards to see the slope ahead; when descending a hill, the light needs to be focused downwards on the road surface; and when traversing off-road terrain, the side lighting coverage needs to be expanded. This makes "flexible and rapid adjustment of the illumination angle" a core functional requirement for LED lamps used in off-road vehicles, and the device for adjusting the illumination angle has thus become a key component of off-road vehicle lighting systems.

[0003] Currently, most LED lighting fixtures on the market still rely on manual adjustment for their angle adjustment. These devices typically use bolts to secure the lampshade or main body, requiring manual loosening of the bolts, rotation of the fixture to the target angle, and then re-tightening. For off-road vehicles, manual adjustment presents several drawbacks: firstly, it cannot be operated in real-time while driving, requiring the vehicle to be stopped and adjusted, severely impacting driving continuity and convenience; secondly, off-road vehicles often have LED lights mounted in specific locations such as the roof or bumper, requiring manual adjustment to bend over, climb, or crawl under the vehicle, a cumbersome and time-consuming process. In complex off-road environments, this also poses safety risks such as collisions and slips, failing to meet the demands for efficient and convenient use in off-road vehicles.

[0004] Even those few LED angle adjustment devices with automatic adjustment functions have significant technical defects and cannot be adapted to the usage scenarios of off-road vehicles. Some devices use gear or belt drive structures, which require high precision in component machining. Long-term use in the bumpy and vibrating driving environment of off-road vehicles can easily lead to transmission jamming or angle deviation due to gear wear or belt loosening, resulting in high maintenance costs. Other devices directly drive the lamp rotation with a simple motor, lacking stable limiting mechanisms and buffer designs. This results in low lamp angle control precision during adjustment, prone to overshoot or inaccurate positioning. Furthermore, their complex overall structure and large size make them incompatible with the installation requirements of different LED lamp specifications in off-road vehicles, limiting their application in off-road scenarios. Utility Model Content

[0005] The present invention aims to solve the technical problems of existing LED lamp angle adjustment devices, such as cumbersome manual adjustment, safety hazards, transmission failures, low angle control accuracy, and poor adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for adjusting the angle of a lamp illumination, comprising:

[0008] A V-shaped swing plate, one end of which is fixed to the housing of the LED lamp;

[0009] The U-shaped bracket is rotatably connected to the LED light fixture via two rotating connecting shafts on both sides, and the V-shaped swing plate is fixed on one of the rotating connecting shafts.

[0010] The push rod motor drives the V-shaped swing plate to swing through the push rod on it, thereby adjusting the angle of the LED lamp relative to the U-shaped bracket, thus changing the illumination angle of the LED lamp.

[0011] Preferably, the top of both sides of the U-shaped bracket is integrally formed with an upwardly inclined portion, one of which is fixed with an external threaded rod A. The fixed block A with a hole at the fixed end of the push rod motor is sleeved on the outer side of the external threaded rod A, and the two sides of the fixed block A with a hole are limited by two nuts A threadedly sleeved on the external threaded rod A.

[0012] Preferably, the end of the V-shaped swing plate away from the LED lamp is fixed with an external threaded rod B, and the perforated fixing block B at the end of the push rod is sleeved on the outer side of the external threaded rod B, and the two sides of the perforated fixing block B are limited by two nuts B threadedly sleeved on the external threaded rod B.

[0013] Preferably, the bottom of the U-shaped bracket is provided with mounting holes to facilitate the installation and fixation of the U-shaped bracket.

[0014] Preferably, one end of the V-shaped swing plate is fixed to the housing of the LED lamp with screws, which is convenient for fixing.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] (1) Compared with traditional manual adjustment devices, this utility model realizes automatic adjustment of the lamp angle through push rod motor, eliminating the need to manually loosen bolts after parking or bend over / climb to operate in special positions on the vehicle body (roof, bumper). During off-road driving, the angle can be adjusted in real time according to road conditions such as climbing, descending, and complex terrain, which not only ensures driving continuity but also avoids the risk of bumps and slips caused by manual operation in the wild environment, greatly improving the convenience and safety of off-road vehicle lighting adjustment, and perfectly adapting to dynamic driving scenarios.

[0017] (2) Compared with automatic adjustment devices driven by gears and belts, this utility model uses a push rod to directly push the V-shaped swing plate, reducing the transmission components that are sensitive to vibration and prone to wear. In the complex driving environment of off-road vehicles with bumps and vibrations, it can effectively avoid problems such as gear wear and belt loosening causing jamming and angle deviation, reduce the failure rate and field maintenance frequency, and extend the service life of the device; at the same time, relying on the limiting cooperation of the external thread rod and nut, combined with the linear drive characteristics of the push rod motor, it can accurately control the lamp angle, avoid overshoot and inaccurate positioning, and ensure the lighting stability of scenarios such as upward focusing of climbing lighting and road surface focusing of downhill lighting.

[0018] (3) The overall structure of this utility model is simple and compact, and its size is small. With the help of the U-shaped bracket mounting holes, it can be flexibly adapted to different installation positions such as the roof and bumper of off-road vehicles. Through the detachable connection between the fixed block with holes and the threaded rod, it can be compatible with LED lamps of different specifications, solving the problems of complex structure and poor adaptability of traditional devices. In addition, the connection method of each component is simple (such as the V-shaped swing plate is fixed by screws and the push rod motor is limited by nuts). Installation does not require complicated tools. Daily maintenance only requires checking the tightness of the nuts and the operation of the motor, which is suitable for temporary maintenance in the field and further reduces the cost of use and maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following combination Figures 1 to 4 This application will be described in further detail.

[0026] This embodiment discloses a device for adjusting the illumination angle of LED lamps, which can flexibly adjust the illumination angle of LED lamps, including a V-shaped swing plate 1, a U-shaped bracket 3, and a push rod motor 5;

[0027] One end of the V-shaped swing plate 1 is fixed to the housing of the LED lamp 2 by screw 15, and the end of the V-shaped swing plate 1 away from the LED lamp 2 is fixed with an external threaded rod B11.

[0028] The U-shaped bracket 3 is rotatably connected to the LED lamp 2 through two rotating connecting shafts 4 on both sides. The bottom of the U-shaped bracket 3 is provided with mounting holes 14 for overall fixation. The top of both sides of the U-shaped bracket 3 are integrally formed with upwardly inclined parts 7, and one of the inclined parts 7 is fixed with an external threaded rod A8.

[0029] The push rod motor 5 is equipped with a telescopic push rod 6, with a fixed end having a perforated fixing block A9 and the end of the push rod 6 having a perforated fixing block B12.

[0030] Two nuts A10 are threaded onto the external threaded rod A8, and two nuts B13 are threaded onto the external threaded rod B11.

[0031] The push rod motor 5 is fitted onto the outside of the external threaded rod A8 via a perforated fixing block A9, and is limited by two nuts A10 on both sides of the perforated fixing block A9, thus enabling the detachable installation of the fixed end.

[0032] The push rod 6 is fitted onto the outside of the external threaded rod B11 through the perforated fixing block B12, and is limited by two nuts B13 on both sides of the perforated fixing block B12, so as to realize the movable connection between the push rod and the V-shaped swing plate 1.

[0033] The V-shaped swing plate 1 is fixed on one of the rotating connecting shafts 4 and rotates synchronously with the rotating connecting shaft 4.

[0034] After the push rod motor 5 is started, its push rod 6 extends and retracts, pushing the V-shaped swing plate 1 to swing around the rotating connecting shaft 4. The V-shaped swing plate 1 drives the LED lamp 2 to rotate relative to the U-shaped bracket 3, thereby changing the illumination angle of the LED lamp 2 to meet the lighting needs of different scenarios.

[0035] The entire device is fixed in the designated installation position through the mounting holes 14 at the bottom of the U-shaped bracket 3.

[0036] Start the push rod motor 5, and adjust the LED lamp 2 to the required angle by controlling the extension and retraction stroke of the push rod 6 to complete the lamp angle calibration.

[0037] This utility model achieves overall fixation through the mounting hole 14 at the bottom of the U-shaped bracket 3. After the push rod motor 5 is started, its push rod 6 extends and retracts, pushing the V-shaped swing plate 1, which is fixed to the LED lamp 2 by a screw 15 and fixed on the rotating connecting shaft 4, to swing around the rotating connecting shaft 4. This causes the LED lamp 2 to rotate relative to the U-shaped bracket 3, ultimately achieving the adjustment of the illumination angle. Compared with the prior art, there is no need to manually loosen or tighten the bolts, avoiding the safety hazards of operating at heights, and making the operation more convenient and efficient. In the complex driving environment of off-road vehicles with bumps and vibrations, it can effectively avoid the problems of gear wear, belt loosening causing jamming and angle deviation, reducing the failure rate and field maintenance frequency, and extending the service life of the device. With the limiting cooperation of the external thread rod A8 and nut A10, and the external thread rod B11 and nut B13, the angle control is precise and without overshoot. At the same time, the overall structure is simple and compact. Through the flexible connection of the perforated fixing block A9 and the perforated fixing block B12, it can be adapted to LED lamps 2 of different specifications. Moreover, the installation is flexible due to the U-shaped bracket 3, making it applicable to a wider range of scenarios.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
