Description

Technical Field

[0001] This utility model relates to the field of auxiliary vehicle lighting technology, specifically a device for expanding the beam angle of auxiliary vehicle lights through a rotating mechanism. Background Technology

[0002] In the field of automotive auxiliary lighting, auxiliary lights play an irreplaceable role as a key component to ensure driving safety. They effectively compensate for the lighting limitations of original headlights in specific environments and driving needs. Original headlights (especially low beams) are limited by regulations and design, and their illumination distance and width are often insufficient to meet all driving scenarios. Auxiliary lights can significantly improve long-distance visibility on the road ahead, or provide wider side illumination on wide roads, allowing drivers to detect potential dangers earlier and increase reaction time.

[0003] Traditional auxiliary vehicle lights are limited by the initial optical design and usually only have a fixed single light emission angle. The angle of the emitted diffused light is strictly limited to a specific range. From the perspective of practical application scenarios, when it is necessary to achieve large-angle light emission to cover a wider side or oblique area, or small-angle light emission to focus light for long-distance illumination, the traditional solution has obvious shortcomings. To achieve large-angle or small-angle light emission effects, the traditional solution is to change the optical design or replace the optical components.

[0004] However, both methods have obvious drawbacks. Changing the optical design is costly, requiring re-development, testing and verification, which consumes a lot of time and resources. Replacing optical components not only increases production costs, but also makes vehicle maintenance and repair complicated and expensive. Therefore, in order to address the above problems, a device is proposed to extend the light-emitting angle of the auxiliary headlights by rotating the mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a device that extends the beam angle of auxiliary vehicle lights through a rotating mechanism, so as to solve the problems mentioned in the background art.

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

[0007] A device for extending the beam angle of auxiliary vehicle lights via a rotating mechanism includes multiple LED lights and a support frame. A rotating shaft mechanism is mounted on one side of each LED light, and a support frame is also mounted on the other side. The rotating shaft mechanism includes a metal connector, a metal snap-fit ​​component is engaged with the inner side of the metal connector, a fixing bolt is inserted into the metal connector, a round-headed rivet is inserted into the metal connector, and an adjusting bolt is inserted into the metal snap-fit ​​component. The metal connector includes a connector body, a first vertical mounting hole and a curved hole are formed on the inner side of the connector body, a first side mounting hole is formed on the side of the connector body away from the metal snap-fit ​​component, and a first through hole is formed on the side of the connector body away from the metal snap-fit ​​component. The metal snap-fit ​​component includes a snap-fit ​​component body, a second vertical mounting hole and a fixing mounting hole are formed on the inner side of the snap-fit ​​component body, a second side mounting hole is formed on the side of the snap-fit ​​component body away from the metal connector, and a second through hole is formed on the side of the snap-fit ​​component body away from the metal connector.

[0010] As a further optimization of this utility model, the outer side of the metal snap-fit ​​component is in close contact with the inner side of the metal connector component, and two round-head rivets are provided. The two round-head rivets are respectively connected to the metal connector component and the metal snap-fit ​​component, and the central axes of the two round-head rivets are on the same straight line.

[0011] As a further optimization of this utility model, two adjusting bolts are provided, which are symmetrically distributed vertically. The adjusting bolts are simultaneously installed in the curved hole and the fixed mounting hole, and the length of the screw portion of the adjusting bolt is 6mm.

[0013] As a further optimization of this utility model, the thickness of the main body of the connector is 2mm, the thickness of the main body of the snap-fit ​​component is 2mm, the first vertical mounting hole, the first side mounting hole, the second vertical mounting hole and the second through hole have the same shape and are all adapted to the fixing bolt, and the diameter of the first through hole is 1.2 times the diameter of the rivet rod of the round head rivet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the clever combination of the rotating shaft mechanism and LED lights enables flexible adjustment of the auxiliary vehicle light beam angle. Mechanical innovation replaces optical reconstruction, achieving dynamic lighting for "one light in multiple scenarios," significantly reducing safety hazards in complex road conditions. At the same time, by reasonably adjusting the beam angle of the vehicle lights, glare interference to other road users can also be reduced, improving the overall driving safety and comfort of the road.

[0033] 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.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Please see Figures 1-11 This utility model provides a technical solution:

[0036] A device for extending the beam angle of auxiliary vehicle lights via a rotating mechanism includes multiple LED lights 1 and a support frame 3. A rotating shaft mechanism 2 is mounted on one side of each LED light 1, and the support frame 3 is also mounted on the same side. The rotating shaft mechanism 2 includes a metal connector 21, with a metal snap-fit ​​component 22 engaged inside the metal connector 21. A fixing bolt 23 and a round-headed rivet 24 are inserted into the metal connector 21. An adjusting bolt 25 is inserted into the metal snap-fit ​​component 22. The metal connector 21 includes a connector body 2101, with a first vertical mounting hole 2102 inside the connector body 2101. A curved hole 2103 is provided on the side of the connector body 2101. A first side mounting hole 2104 is provided on the side of the connector body 2101 away from the metal snap-fit ​​22. A first through hole 2105 is provided on the side of the connector body 2101 away from the metal snap-fit ​​22. The metal snap-fit ​​22 includes a snap-fit ​​body 2201. A second vertical mounting hole 2202 is provided on the inner side of the snap-fit ​​body 2201. A fixed mounting hole 2203 is provided on the inner side of the snap-fit ​​body 2201. A second side mounting hole 2204 is provided on the side of the snap-fit ​​body 2201 away from the metal connector 21. A second through hole 2205 is provided on the side of the snap-fit ​​body 2201 away from the metal connector 21.

[0037] As a further implementation of this solution, multiple rotating shaft mechanisms 2 are provided, and these multiple rotating shaft mechanisms 2 are interleaved with multiple LED lamps 1. The distance between two adjacent LED lamps 1 is 10mm. The interleaved design of multiple rotating shaft mechanisms 2 and multiple LED lamps 1 allows multiple rotating shaft mechanisms 2 to control their respective LED lamps 1. This design allows the light emission angle of each LED lamp 1 to be adjusted independently or to be adjusted collaboratively in a certain combination. The 10mm distance between two LED lamps 1 allows the light beams to blend better, avoiding the problem of light spot separation or large light intensity differences caused by excessive lamp spacing. This improves the uniformity of illumination in the entire lighting area, allowing drivers to obtain a clearer and more comfortable visual effect when driving at night.

[0038] As a further implementation of this solution, the LED lamp 1 has a light-emitting surface size of 20mm × 15mm. An optical lens is installed at the front end of the LED lamp 1. The radius of curvature of the optical lens at the front end of the LED lamp 1 is 25mm (adjustable screw). The focal length of the optical lens at the front end of the LED lamp 1 is 18mm. The relatively small and compact 20mm × 15mm light-emitting surface size of the LED lamp 1 allows the light beam after passing through the optical lens at the front end of the LED lamp 1 to be more evenly distributed in the illumination area, avoiding problems such as uneven light intensity, excessively bright center of the light spot and excessively dark edge, thereby improving the uniformity and overall quality of the lighting effect. The 25mm radius of curvature allows the optical lens to balance the diffusion and focusing performance of the light beam to a certain extent, preventing the light beam from being too diffused and reducing the light intensity, and preventing over-focusing and making the beam range too narrow. At the same time, the 18mm focal length allows the optical lens to focus the light emitted by the LED lamp 1 at a relatively close distance, while still ensuring a certain projection range, meeting the needs of close and medium distance lighting under normal vehicle lighting conditions.

[0039] As a further implementation of this solution, the outer side of the metal clip 22 is tightly attached to the inner side of the metal connector 21. Two round-headed rivets 24 are provided, and the two round-headed rivets 24 are connected to the metal connector 21 and the metal clip 22 respectively. The central axes of the two round-headed rivets 24 are on the same straight line. The outer side of the metal clip 22 is tightly attached to the inner side of the metal connector 21, which increases the contact area between the two and makes the force distribution more even. During the vehicle's operation, whether it is the vibration caused by bumpy road surface or the impact force generated when the vehicle accelerates or brakes, this tightly attached structure can effectively reduce the relative displacement and shaking between the components, thereby enhancing the structural stability of the entire device.

[0040] As a further implementation of this solution, two adjusting bolts 25 are provided, which are symmetrically distributed vertically. The adjusting bolts 25 are simultaneously installed in the curved hole 2103 and the fixed mounting hole 2203. The length of the screw part of the adjusting bolt 25 is 6mm. The symmetrical distribution of the two adjusting bolts 25 allows for a more even application of force to the rotating shaft mechanism 2 during the adjustment process, avoiding problems such as uneven force distribution and skewing caused by single-point adjustment. The 6mm long screw part of the adjusting bolt 25 provides sufficient screw depth to insert into the curved hole 2103 and the fixed mounting hole 2203, providing a stable connection and adjustment force.

[0041] As a further implementation of this solution, the adjusting bolt 25 is matched with the fixed mounting hole 2203. The curved hole 2103 is arc-shaped, and the top of the curved hole 2103 faces away from the first vertical mounting hole 2102. The adjusting bolt 25 is slidably connected inside the curved hole 2103. The arc shape of the curved hole 2103 provides an arc-shaped path for the movement of the adjusting bolt 25. When it is necessary to adjust the light emission angle of the LED lamp 1, the adjusting bolt 25 can slide along the arc in the curved hole 2103, thereby allowing the LED lamp 1 to be flexibly adjusted within a certain angle range.

[0042] As a further implementation of this solution, the thickness of the connector body 2101 is 2mm, the thickness of the snap-fit ​​body 2201 is 2mm, the first vertical mounting hole 2102, the first side mounting hole 2104, the second vertical mounting hole 2202, and the second through hole 2205 are identical in shape and all are compatible with the fixing bolt 23. The diameter of the first through hole 2105 is 1.2 times the diameter of the rivet shank of the round-head rivet 24. The thickness of both the connector body 2101 and the snap-fit ​​body 2201 is 2mm. This design effectively reduces the overall weight while ensuring connection strength and structural stability. The first vertical mounting hole 2102, the first side mounting hole... The design of 2104, the second vertical mounting hole 2202, and the second through hole 2205 having the same shape and being compatible with the fixing bolt 23 eliminates the need to use multiple bolts or installation tools of different specifications during assembly, greatly improving the convenience and efficiency of assembly. The redundant space between the round head rivet 24 and the hole wall of the first through hole 2105 or the second through hole 2205 can prevent the metal connector 21 and the metal snap fastener 22 from excessively constraining the round head rivet 24, and prevent the round head rivet 24 from exerting a large force on the LED lamp 1 structure when the metal connector 21 and the metal snap fastener 22 move, which could lead to damage or failure of the LED lamp 1.

[0043] Workflow: During installation, a round-headed rivet 24 is first used to fix the device to the LED lamp 1 by passing through the first through hole 2105. A fixing bolt 23 is then used to connect the device to the threaded hole in the mounting base of the LED lamp 1 by passing through the first side mounting hole 2104 in the main body 2101 of the connector. Next, another round-headed rivet 24 is used to fix the device to another LED lamp 1 by passing through the second through hole 2205. A fixing bolt 23 is then used to connect the device to the threaded hole in the mounting base of another LED lamp 1 by passing through the second side mounting hole 2204 in the main body 2201 of the snap-fit ​​connector. When tightening the fixing bolt 23, observe whether the round-headed rivet 24 is aligned with the corresponding first through hole 2105 or second through hole 2105. A certain clearance fit is formed between 205 to ensure that there is a certain amount of play between the round head rivet 24 and the hole wall of the first through hole 2105 or the second through hole 2205. Then, the connector body 2101 and the snap-fit ​​body 2201 installed on the LED lamp 1 are spliced ​​together so that the snap-fit ​​body 2201 snaps into the connector body 2101, and the first vertical mounting hole 2102 is aligned with the second vertical mounting hole 2202. The fixing bolt 23 is passed through the first vertical mounting hole 2102 and the second vertical mounting hole 2202 to fix the connector body 2101 and the snap-fit ​​body 2201. Then, the adjusting bolt 25 is passed through the curved hole 2103 and fixed in the fixing mounting hole 2203, thus completing the connection of the metal connector 21 and the metal The combination and fixation of the snap-fit ​​22 allows the rotating shaft mechanism 2 to connect and support the two LED lamps 1. After installing all the LED lamps 1 sequentially, the two support frames 3 are installed on the two outermost LED lamps 1 respectively. The entire device is then installed onto the vehicle using the support frames 3. At this point, the multiple LED lamps 1 are in a normal installation configuration. Power is supplied to the LED lamps 1, and it is observed whether the light emission direction of the multiple LED lamps 1 is consistent and whether a normal illumination range can be formed. Next, the installation angle of the metal connector 21 and the metal snap-fit ​​22 is changed. Because the curved hole 2103 is arc-shaped and the adjusting bolt 25 can slide within the curved hole 2103, the metal connector 21 and the metal snap-fit ​​22 are fixedly connected to the LED lamps 1. The LED lamp 1 can deflect to a certain extent. When the metal connector 21 and the metal clip 22 are relatively displaced, the redundant space between the round head rivet 24 and the hole wall of the first through hole 2105 or the second through hole 2205 can prevent the metal connector 21 and the metal clip 22 from excessively constraining the round head rivet 24, and prevent the round head rivet 24 from exerting a large force on the structure of the LED lamp 1, which would cause damage or failure of the LED lamp 1. When the adjustment causes multiple LED lamps 1 to rotate outward by a certain angle, a wider illumination range can be formed to illuminate more areas on both sides of the vehicle. When the adjustment causes multiple LED lamps 1 to rotate inward by a certain angle, a more focused illumination range can be formed to illuminate a more distant area directly in front of the vehicle.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
