Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive roof projection light and vehicle. Background Technology

[0002] To enhance the user experience, different starry sky patterns are often displayed on car roofs. Currently, fiber optic technology is commonly used to achieve this effect. This involves embedding optical fibers within the roof, then shining light into the fibers, which are then guided outwards. By mimicking the random distribution of stars in the sky, the starry sky effect is achieved. However, achieving this effect requires embedding a large number of optical fibers, making production complex. Furthermore, optical fibers can only display point effects, resulting in a limited range of visual possibilities and a relatively simple manufacturing process, failing to meet the diverse needs of users. Utility Model Content

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a car roof projection light, including a fixed box, a PCB board installed inside the fixed box, a light source lens installed on the PCB board, the PCB board being electrically connected to the light source lens, a refractive lens installed inside the fixed box, and a light-emitting lens installed on the side wall of the fixed box. The light source lens emits light onto the refractive lens, the refractive lens reflects the light onto the light-emitting lens, and the light-emitting lens projects the light onto the outside of the fixed box. A rotating component is installed inside the fixed box, and the rotating component is kinetically connected to the refractive lens.

[0005] Preferably, the rotating component includes a motor and a reducer. The motor drives the output shaft to rotate. A first gear is mounted on the output shaft and meshes with the reducer. A rotating shaft is mounted on the back of the refracting lens, and a second gear is mounted on the rotating shaft and meshes with the reducer.

[0006] Preferably, the reducer includes an intermediate shaft, with a first mating gear and a second mating gear respectively mounted at both ends of the intermediate shaft. The first mating gear meshes with the first gear, and the second mating gear meshes with the second gear. The number of teeth of the second gear is greater than the number of teeth of the first gear.

[0007] Preferably, the fixing box includes a first cavity, a second cavity, and a connecting cavity. The first cavity and the second cavity are connected through the connecting cavity. A slot is formed in the first cavity, and the light source lens is inserted into the slot. A rotating component and a refractive lens are installed in the second cavity.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0017] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0019] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0020] Under current technology, optical fibers are usually pre-embedded in the roof, and then light is guided through the optical fibers to achieve the effect of a starry sky roof inside the vehicle. However, it can only display the starry sky effect and cannot display other patterns, so the style is relatively simple. At the same time, pre-embedding optical fibers in the roof is a complicated process, and the large number of pre-embedded optical fibers will reduce the production cycle and increase the processing cost.

[0021] To solve the above problems, such as Figures 1 to 2As shown, this utility model provides a car roof projection light, including a fixing box 1, a PCB board 2 installed inside the fixing box 1, a light source lens 4 installed on the PCB board 2, the PCB board 2 and the light source lens 4 being electrically connected, a refraction lens 5 installed inside the fixing box 1, and a light-emitting lens 6 installed on the side wall of the fixing box 1. The light source lens 4 emits light onto the refraction lens 5, the refraction lens 5 reflects the light onto the light-emitting lens 6, and the light-emitting lens 6 projects the light onto the outside of the fixing box 1. A rotating component 7 is installed inside the fixing box 1, and the rotating component 7 is connected to the refraction lens 5 through a transmission connection, providing power to the PCB board 2 through the vehicle's power supply.

[0022] The light-emitting lens 6 can emit light when the PCB board 2 is powered on. The light is then reflected by the refracting lens 5 and finally emitted from the light-emitting lens 6.

[0023] The fixing box 1 can be fixed to the roof inside the vehicle. The light projected from the light-emitting lens 6 will eventually shine on the roof inside the vehicle. Different patterns can be displayed on the light-emitting lens 6 and the refraction lens 5, such as starry sky, universe, landscape or people, so that the roof can display more and more effects and make the display effect richer. At the same time, by changing the position of the rotating component 7, the light projected on the roof can be changed, so that the pattern projected by the light on the roof can change dynamically and make the display content richer.

[0024] The rotating component 7 includes a motor 71 and a reducer 72. The motor 71 drives the output shaft to rotate. A first gear 73 is mounted on the output shaft and meshes with the reducer 72. A rotating shaft 51 is mounted on the back of the refractive lens 5. A second gear 74 is mounted on the rotating shaft 51 and meshes with the reducer 72.

[0025] After the motor 71 starts, it rotates at a high speed. The speed reduction is achieved by the reducer 72, which makes the movement of the refracting lens 5 more slow, making the movement of the pattern finally projected on the roof more reasonable and the projection effect of the car roof projection light more realistic.

[0026] The reducer 72 includes an intermediate shaft 721, with a first mating gear 722 and a second mating gear 723 respectively mounted at both ends of the intermediate shaft 721. The first mating gear 722 meshes with the first gear 73, and the second mating gear 723 meshes with the second gear 74. Since the number of teeth of the second gear 74 is greater than the number of teeth of the first gear 73, after the motor 71 is transmitted to the refracting lens 5 through the reducer 72, the rotation speed of the refracting lens 5 is reduced, which can simulate the rotation of stars and make the practical effect more realistic.

[0027] The fixing box 1 includes a first cavity 11, a second cavity 12, and a connecting cavity 13. The first cavity 11 and the second cavity 12 are connected through the connecting cavity 13. A slot 14 is formed in the first cavity 11, and the light source lens 4 is inserted into the slot 14. A rotating component 7 and a refractive lens 5 are installed in the second cavity 12. A light-emitting lens 6 is installed on the side wall of the connecting cavity 13. The connecting cavity 13 is connected to both the first cavity 11 and the second cavity 12. The light changes direction in the connecting cavity 13 and is not blocked, which also reduces the volume of the fixing box 1.

[0028] Different parts are installed in different cavities. The light source lens 4 is fixed by the slot 14 to prevent the light source in the car roof projection light from shaking during the car's driving process, thereby improving the display effect and reducing passenger discomfort.

[0029] During the operation of PCB board 2, a large amount of heat is generated due to the need to emit light. A heat sink 3 is attached to the other side of PCB board 2. Heat sink 3 has heat dissipation fins 31 on its side. The heat dissipation fins 31 can increase the contact area with air, thereby cooling down PCB board 2, extending the service life of PCB board 2, and improving the reliability of automotive roof projection light.

[0030] The vehicle is equipped with a roof, and car roof projection lights are installed at the corners of the roof. The vehicle has a built-in power supply, which is electrically connected to PCB board 2. The light shines onto the car roof. A controller is installed inside the vehicle and is electrically connected to PCB board 2. The controller can adjust the intensity of the light emitted by the light source lens 4 and change the color of the light emitted by the light source lens 4.

[0031] Because the vehicle screen is electrically connected to the controller, users can adjust different colors and brightness according to their needs, allowing the light source lens 4 to project different colors and brightness, so that the brightness and color of the pattern projected by the final car roof projection light can be adjusted as needed.

[0032] At least two sets of car roof projection lights are installed on the roof. When the light beams overlap, they form a pattern. The area projected by the car roof projection is fan-shaped. If the area of ​​the roof is too large, multiple car roof projection lights need to be installed at the edge of the car roof to increase the projection area. The projection areas of different car roof projection lights can also be overlapped so that the overlapping areas can be pieced together to form different patterns. The controller can calculate the pattern that the car roof projection lights in different positions need to project, so that multiple car roof projection lights can ultimately project in a unified and coordinated manner to project the pattern required by the user onto the car roof.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
