Description

Technical Field

[0001] This utility model relates to the field of automotive lighting equipment technology, and in particular to vehicle warning lights. Background Technology

[0002] "Vehicle warning lights" are signal lights installed on vehicles to warn other road users. Their function is to improve the vehicle's visibility in specific situations and remind surrounding vehicles and pedestrians to pay attention to safety. Depending on the application scenario and function, vehicle warning lights can be divided into several types. For example, there are construction vehicle warning lights used by special-operation vehicles such as road maintenance vehicles, sanitation vehicles, and construction vehicles to indicate that work is in progress and warn surrounding vehicles to give way; there are also police or rescue-specific warning lights used by public security, fire, and emergency vehicles, etc.

[0003] These warning lights typically operate in harsh environments. For example, warning lights on engineering vehicles are constantly exposed to harsh conditions such as flying sand and gravel even when not in use, which can easily cause damage or shorten their lifespan. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides a vehicle warning light. By setting a baffle that can cover the light body, the warning light is protected when it is not in use, thereby avoiding damage from external forces and extending its service life.

[0005] The technical solution adopted by this utility model is to design a vehicle warning light, including a long strip-shaped light body. The bottom of the light body is provided with a bracket for connecting to the outside of the vehicle body. The bracket is provided with a baffle that can rotate relative to the light body. The baffle is controlled to rotate by a rotating device, so that the baffle covers or moves away from the top of the light body.

[0006] In some embodiments, the baffle is provided with a reflective layer facing the inner side of the lamp body.

[0007] In some embodiments, a solar cell is provided on the upward-facing top surface of the lamp body.

[0008] In some embodiments, a solar cell is provided on the outer side of the baffle facing away from the lamp body.

[0009] In some embodiments, light-emitting elements are provided on both opposite sides of the lamp body in the horizontal direction.

[0010] In some embodiments, the baffle includes a first plate and a second plate located on both sides of the lamp body, the first plate and the second plate being rotatably connected to the bracket via rotating shafts, the rotating device including worm gears and worms connected to the two rotating shafts respectively, the worms being driven to rotate by a motor, the worms having two threads that mesh with the two worm gears respectively, the helical directions of the two threads being opposite.

[0011] In some embodiments, the pivot is located at the bottom of the lamp body, and the first plate and the second plate are bent plates, the bending profile of the bent plates being the same as the profile of the side of the lamp body.

[0012] In some embodiments, the portion of the first plate and the second plate located above the lamp body is greater than half the width of the lamp body, so that the first plate and the second plate can form a herringbone structure when located above the lamp body.

[0013] In some embodiments, one of the first plate and the second plate has a folded edge on its side that can cover the other plate.

[0014] In some embodiments, a first bevel gear is coaxially fixed at the middle of the worm gear, the first bevel gear meshing with a second bevel gear, and the second bevel gear being driven to rotate by a motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves a multifunctional design that integrates lamp protection, light control, and energy self-sufficiency by introducing a rotatable baffle, reflective layer, and solar cell into the structure of the vehicle warning light.

[0016] Driven by the motor and worm gear mechanism, the baffle can form a "V" shaped shielding structure, which can cover the top of the lamp body when the vehicle is stopped or the lights are off, effectively preventing external impact, dust and rainwater erosion, and extending the lamp body's service life.

[0017] Secondly, the baffle's adjustable angle allows the inner reflective layer to directionally reflect light, achieving efficient warning of specific areas and improving the visibility and flexibility of the warning light. Simultaneously, the controllable adjustment of the baffle's angle also helps reflect sunlight to the solar cells at the top of the light unit, improving light utilization and power generation efficiency, and enabling efficient charging of the battery during the day.

[0018] Furthermore, solar cells are installed on the outer side of the baffles to replenish power under different lighting angles, enhancing the system's energy acquisition capabilities. Through a transmission linkage structure of worm gear and bevel gear, the two baffles can achieve synchronous and opposite-direction precise rotation, ensuring stable and reliable movement and preventing jamming due to inconsistent deflection. The overall structure is compact, significantly improving protection, intelligence, and energy efficiency, making it suitable for intelligent warning lighting systems in various vehicles.

[0024] The following are specific embodiments of this utility model, and the technical solution of this utility model will be further described with reference to the accompanying drawings. However, this utility model is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, all combinations of features described in the embodiments are not necessarily necessary for the solution of the utility model.

[0025] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. Example

[0026] like Figure 1 , 2 As shown in Figures 3 and 4, the vehicle warning light includes a long strip-shaped light body 1. The bottom of the light body 1 is provided with a bracket 14 for connecting to the outside of the vehicle body 2. The bracket 14 is usually connected to the outside of the vehicle roof.

[0027] The bracket 14 is provided with a baffle that can rotate relative to the lamp body 1. The baffle is controlled to rotate by a rotating device, so that the baffle covers the lamp body 1 or moves away from the lamp body 1. When the light is not needed, the baffle covers the lamp body 1 to protect it. When the light is needed, the baffle moves away from the lamp body 1 so as not to affect the lamp body 1 from providing warning light to the surroundings.

[0028] The baffle is provided with a reflective layer 3 on the inner side facing the lamp body 1. The angle of the baffle can be adjusted by rotating the device so that the light can be reflected to the direction that needs to be warned as needed.

[0029] A solar cell 4 is provided on the top surface of the lamp body 1, which can be used to provide power for the warning light. For example, a battery can be installed inside the lamp body 1 to store the electrical energy generated by the solar cell 4. When the warning light is not needed, the angle of the baffle can be adjusted by rotating the device so that the reflective layer 3 reflects sunlight onto the solar cell 4 on the lamp body 1, thereby providing power for the solar cell 4.

[0030] A solar cell 4 can also be installed on the outer side of the baffle opposite to the lamp body 1, so that solar energy can also be used to generate electricity.

[0031] In this embodiment, light-emitting elements 5 are provided on two opposite sides of the lamp body 1 in the horizontal direction. In this embodiment, the light-emitting elements 5 are LED lights. The baffle includes a first plate 6 and a second plate 7 located on both sides of the lamp body 1. The first plate 6 and the second plate 7 are rotatably connected to the bracket 14 via rotating shafts 8. The rotating device includes worm gears 9 and worm 10 connected to the two rotating shafts 8 respectively. The worm 10 is driven to rotate by a motor 13. The worm 10 has two sections of thread that mesh with the two worm gears 9 respectively. The helical directions of the two sections of thread are opposite, and the two worm gears 9 are located on the same side of the worm 10.

[0032] The rotating shaft 8, worm gear 9, and worm 10 are all located at the bottom of the lamp body 1. The first plate 6 and the second plate 7 are bent plates. The bending profile of the bent plate is the same as the profile of the side of the lamp body 1. Therefore, when the plate is located above the lamp body 1, the bent part of the plate fits better with the side of the lamp body 1, resulting in a compact structure.

[0033] The portion of the first plate 6 and the second plate 7 located above the lamp body 1 is greater than half the width of the lamp body 1, so that the first plate 6 and the second plate 7 can form a herringbone structure when located above the lamp body 1.

[0034] Thus, when the motor 13 drives the worm gear 10 to rotate, it can simultaneously drive the two worm wheels 9 to rotate in opposite directions, that is, drive the first plate 6 and the second plate 7 to rotate relative to each other, thereby making the first plate 6 and the second plate 7 approach or move away from each other. When the first plate 6 and the second plate 7 are close to each other, they can form a V-shaped shielding structure above the lamp body 1, thereby preventing the lamp body 1 from being damaged by external forces. When the first plate 6 and the second plate 7 are far apart from each other, they can rotate to the bottom of the lamp body 1, thereby avoiding obstructing the lamp body 1 from emitting warning lights to the surroundings.

[0035] One of the two plates, the first plate 6 and the second plate 7, has a folded edge 61 on its side that can cover the other plate. In this embodiment, the first plate 6 is provided with the folded edge 61, which is a bent edge relative to the plate, thereby avoiding an upward gap when the first plate 6 and the second plate 7 come into contact.

[0036] A first bevel gear 11 is coaxially fixed in the middle of the worm gear 10. The first bevel gear 11 meshes with a second bevel gear 12. The second bevel gear 12 is driven to rotate by a motor 13, thereby controlling the rotation of the two worm wheels 9.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0038] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless a specific order is explicitly specified, and as long as the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.

[0039] Those skilled in the art will understand that all directional references (e.g., above, below, up, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the scope of the invention as defined by the appended claims. They are merely for the purpose of facilitating the description of the application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective components themselves.

[0040] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
