[0061] In order to make the content of the present utility model more clearly understood, the following further detailed description of the present utility model is provided according to specific embodiments in conjunction with the accompanying drawings.

[0062] Embodiment 1

[0063] As Figures 1-4 shown, a vehicle lamp includes:

[0064] A housing 1, on which a light-transmitting surface is provided;

[0065] A light source 2, which is installed inside the housing 1. The light source 2 is provided with a light output path, and the light output path of the light source 2 faces the light-transmitting surface;

[0066] A pattern dynamic projection runner 3, which is rotatably installed inside the housing 1. A plurality of image projection films 31 are uniformly arranged along the circumferential direction on the pattern dynamic projection runner 3, and the light output path of the light source 2 passes through at least one image projection film 31;

[0067] The color filter wheel 4 is rotatably installed in the housing 1. A plurality of color filter films 41 are evenly arranged on the color filter wheel 4 along the circumferential direction, and the light output path of the light source 2 passes through at least one color filter film 41.

[0068] In this embodiment, as Figure 1 , Figure 3 and Figure 4 shown, the light emitted by the light source 2 first passes through the image projection film 31 on the pattern dynamic projection wheel 3, then passes through the color filter film 41 on the color filter wheel 4, and finally exits from the light-transmitting surface of the housing 1. This structure enables the vehicle lamp to simultaneously achieve dynamic changes in patterns and colors. During actual use, the pattern dynamic projection wheel 3 and the color filter wheel 4 can rotate independently, thereby generating a rich variety of light effect combinations, greatly enhancing the display effect and visual experience of the vehicle lamp.

[0069] Of course, in some embodiments, the order in which the light emitted by the light source 2 passes through the pattern dynamic projection wheel 3 and the color filter wheel 4 is not unique and can be set according to needs.

[0070] In this embodiment, the housing 1 is designed to be waterproof to ensure the normal operation of the vehicle lamp under various weather conditions. The vehicle lamp can also automatically select different light colors according to environmental changes, such as adjusting the light color according to weather conditions, to improve driving safety and visual comfort. In addition, the vehicle lamp can also implement a variety of driving assistance functions, including but not limited to navigation direction indication, driving light carpet projection, light output matte extraction, adjusting the light output width according to the road width, and switching the light output width according to the oncoming lane conditions.

[0071] In addition, this embodiment can also be used as outdoor entertainment lighting, such as simulating the color-changing light effect of a KTV to achieve dynamic switching of different colors and patterns. At the same time, this embodiment can also implement a light language function, switching different light languages and colors according to user needs to enhance the interaction ability between the vehicle and the outside world. This embodiment can also perform auxiliary functions such as navigation intersection guidance, road width indication, light carpet projection, and oncoming vehicle light adjustment, further improving driving safety and convenience.

[0072] To meet the personalized needs of users, the pattern shape and color of this embodiment can also be customized according to personal preferences. By providing a variety of pattern and color options, it can meet the diverse needs of vehicle purchasers, not only increasing the beauty of the vehicle but also providing users with a unique visual experience and an opportunity for personalized expression.

[0073] Specifically, as Figure 1 and Figure 4 shown, the vehicle lamp further includes a first rotation drive source 5 and a second rotation drive source 6, and the second rotation drive source 6 is installed in the housing 1;

[0074] The pattern dynamic projection runner 3 includes a sun gear 32, a base frame, and planet gears 33;

[0075] The sun gear 32 is rotatably connected to the base frame;

[0076] The planet gears 33 are rotatably mounted on the base frame along the circumferential direction of the sun gear 32 and are meshed and connected to the sun gear 32;

[0077] The image projection film 31 is mounted on the planet gears 33;

[0078] The first rotation drive source 5 is in transmission connection with the sun gear 32;

[0079] The second rotation drive source 6 is in transmission connection with the base frame;

[0080] The second rotation drive source 6 is adapted to drive the base frame to rotate around the center of the sun gear 32, thereby driving the planet gears 33 and the image projection film 31 on the planet gears 33 to rotate;

[0081] When the second rotation drive source 6 stops, the first rotation drive source 5 is adapted to pass through the sun gear.

[0082] In this embodiment, as Figures 1-2 shown, in the actual use process, different motion modes can be selected according to needs. For example, when the second rotation drive source 6 is started, it drives the base frame to rotate, thereby driving the planet gears 33 and the sun gear 32 on the base frame to rotate together. Among them, the image projection film 31 will rotate accordingly to realize switching of different image projection films 31; when only the first rotation drive source 5 is started, the image projection film 31 will rotate self - rotatably, presenting a rotating and changing pattern; when both drive sources work simultaneously, more complex motion trajectories can be created, making the projected pattern present a unique dynamic effect. This diverse motion mode enables the vehicle lamp to adapt to different usage scenarios, such as daily driving, special occasion display, etc.

[0083] The pattern dynamic projection runner 3 adopts a planetary gear structure design. This design enables the image projection film 31 to achieve complex motion modes, thereby generating rich and variable light and shadow effects. By controlling the operating states of the first rotation drive source 5 and the second rotation drive source 6, self - rotation, revolution, or a combined motion of both of the image projection film 31 can be realized. This flexible motion method enables the projected pattern to present diverse dynamic effects, greatly enhancing the visual attraction and aesthetic degree of the vehicle lamp. In this embodiment, both the first rotation drive source 5 and the second rotation drive source 6 can be motors or other devices capable of outputting rotation.

[0084] Specifically, as Figure 1 and Figure 3As shown, the vehicle headlamp further includes a third rotation drive source 7, and the third rotation drive source 7 is installed in the housing 1;

[0085] The color filter wheel 4 can have the following structure, including:

[0086] A rotating disk body 42, and the rotating disk body 42 is installed on the third rotation drive source 7;

[0087] A plurality of color filter sheets 41 are uniformly arranged on the rotating disk body 42 along the circumference of the rotating disk body 42;

[0088] The third rotation drive source 7 is adapted to drive the rotating disk body 42 to rotate so as to drive the color filter sheets 41 to move circumferentially.

[0089] In this embodiment, as Figure 1 and Figure 3 shown, the working principle of the color filter wheel 4 is to filter the white light emitted by the light source 2 by using color filter sheets 41 of different colors, thereby generating light of various colors. When the third rotation drive source 7 drives the rotating disk body 42 to rotate, the color filter sheets 41 of different colors will sequentially enter the light output path of the light source, making the projected light present a continuously changing color effect. This dynamic color transformation can create a unique visual experience and is particularly eye-catching when used during night driving or special occasions.

[0090] This design not only enhances the aesthetics of the headlamp but also provides more personalized options for the driver.

[0091] In this embodiment, the third rotation drive source 7 can be a motor or other devices capable of outputting rotation.

[0092] Specifically, as Figure 1 shown, the vehicle headlamp further includes a focusing assembly, and the focusing assembly can have the following structure, including:

[0093] A focusing track 101, and the focusing track 101 is installed in the housing 1 along the light output path direction of the light source 2;

[0094] A fixed optical lens 102, and the fixed optical lens 102 is fixed at one end of the focusing track 101;

[0095] A moving slider, and the moving slider is slidably arranged on the focusing track 101;

[0096] An adjustable optical lens 103, and the adjustable optical lens 103 is fixed in the moving slider;

[0097] A transmission lead screw 104, and the transmission lead screw 104 is rotatably installed in the housing 1 along the extension direction of the focusing track 101;

[0098] A nut, which is in threaded engagement with the drive lead screw 104 and fixedly connected to the moving slide frame;

[0099] A focusing drive source 105, which is fixedly installed in the housing 1. The focusing drive source 105 is provided with an output shaft, and the output shaft is coaxially connected to the drive lead screw 104;

[0100] When the focusing drive source 105 drives the drive lead screw 104 to rotate, the drive lead screw 104 is adapted to drive the moving slide frame and the adjustable optical lens 103 on the moving slide frame to move along the focusing track 101 through the nut.

[0101] In this embodiment, as Figure 1 shown, the working principle of the focusing assembly is to utilize the change in the relative position between the adjustable optical lens 103 and the fixed optical lens 102 to change the degree of convergence or divergence of the light beam. This dynamic focusing ability enables the vehicle headlight to always maintain the best lighting effect in different driving scenarios, improving driving safety.

[0102] Specifically, as Figure 1 shown, the light source 2 further includes:

[0103] A reflector 22, which is disposed around the light-emitting path of the light source 2. The reflector 22 is adapted to reflect the light emitted by the light source 2.

[0104] In this embodiment, as Figure 1 shown, the working principle of the reflector 22 is to utilize its bowl-like shape and reflective surface to control the propagation direction of the light. When the light emitted by the light source 2 contacts the inner surface of the reflector 22, it will be reflected and redirected. By carefully designing the curved surface shape of the reflector 22, precise control of the light can be achieved, thereby forming the required light pattern distribution. This reflection mechanism can not only improve the utilization efficiency of the light source but also reduce glare, creating a safer lighting environment for drivers and other road users. It not only enhances the overall brightness of the vehicle headlight but also optimizes the light distribution, improving the uniformity and efficiency of lighting.

[0105] The light source 2 further includes a light distribution lens 110 for more precisely controlling the light distribution and irradiation range. The light distribution lens 110 can be designed according to different driving light sources 2 to achieve a more optimized light output effect. In addition, the light source 2 can be an LED light source or other types of light sources, such as halogen lamps, xenon lamps, or laser light sources, etc. The most suitable light source type can be selected according to specific requirements to meet the lighting needs of different users and different vehicle models.

[0106] Specifically, as Figure 1 shown, the vehicle headlight further includes a light source radiator 23;

[0107] The light source 2 is provided with a light-emitting surface and a non-light-emitting surface opposite to the light-emitting surface;

[0108] The light source radiator 23 is installed on the non-light-emitting surface of the light source 2.

[0109] In this embodiment, as Figure 1 shown, in this implementation manner, the light source radiator 23 solves the heat problem generated by the light source 2 during operation. By installing the light source radiator 23 on the non-light-emitting surface of the light source 2, the heat generated by the light source 2 can be effectively absorbed and dissipated, thereby ensuring the normal operating temperature and service life of the light source 2. This design not only improves the reliability and durability of the vehicle lamp, but also ensures the stable output of the light source 2 and maintains the long-term lighting performance of the vehicle lamp.

[0110] The working principle of the light source radiator 23 is to utilize its large surface area and good heat conduction performance to accelerate heat dissipation. When the heat generated by the light source 2 during operation is conducted to the light source radiator 23 through the non-light-emitting surface, the temperature of the light source 2 is effectively controlled.

[0111] Specifically, as Figure 1 shown, the housing 1 is provided with a wire passing hole;

[0112] The vehicle lamp further includes a lamp connection wire 8. One end of the lamp connection wire 8 is connected to the light source 2, and the other end is adapted to pass through the wire passing hole and extend outside the housing 1.

[0113] In this embodiment, as Figure 1 shown, a control device 120 of the vehicle lamp is also provided in this embodiment. The wire passing hole provided on the housing 1 and the lamp connection wire 8 realize the electrical connection between the vehicle lamp and the control device 120.

[0114] By reserving a wire passing hole on the housing 1 and connecting the light source 2 to the vehicle control device 120 using the lamp connection wire 8, a convenient channel for controlling and powering the vehicle lamp is provided.

[0115] In addition, a waterproof sealing ring can be added at the wire passing hole to improve the waterproof performance and durability of the housing 1.

[0116] The vehicle control device 120 can be an MCU control chip. The specific model of the MCU control chip is well-known to those skilled in the art, and its specific structure is not described in detail in this embodiment.

[0117] Specifically, as Figure 1 shown, the light source 2 is provided with a hinge arm, and the light source 2 is hinged to the housing 1 through the hinge arm;

[0118] The vehicle lamp further includes a light output pitch adjustment device 9, and the light output pitch adjustment device 9 includes:

[0119] The pitch adjustment driving source is installed in the housing 1 and is in transmission connection with the articulated arm. The pitch adjustment driving source is suitable for driving the light source 2 to adjust the pitch around the hinge point through the articulated arm.

[0120] In this embodiment, if Figures 1-2 As shown, the light output pitch adjustment device 9 realizes the pitch angle adjustment of the light source 2 by setting an articulated arm on the light source 2 and articulating it with the housing 1, combined with the function of the pitch adjustment driving source. This design enables the headlight to adjust the lighting angle according to different driving conditions and road conditions, greatly improving driving safety and driving comfort.

[0121] The working principle of the light output pitch adjustment device 9 is to utilize the transmission connection between the pitch adjustment driving source and the articulated arm to change the pitch angle of the light source 2 by controlling the movement of the driving source. When the vehicle is traveling on roads with different slopes, or when the vehicle load changes, the irradiation angle of the light source 2 can be adjusted by this device to ensure that the best lighting effect is always obtained.

[0122] In this embodiment, the pitch adjustment driving source may be a device capable of outputting rotation or swing, such as a steering gear.

[0123] Specifically, Figures 3-4 As shown, adjacent image projection sheets 31 are provided with different pattern features and adjacent color filters 41 are provided with different colors.

[0124] In this embodiment, if Figures 3-4 As shown, by setting different pattern features on adjacent image projections 31 and using different colors on adjacent color filters 41, the headlights can present more diverse and dynamic light effects, greatly improving the aesthetics and personalization of the vehicle.

[0125] The different pattern features on the image projection sheet 31 enable the headlight to project a changing pattern. When the pattern dynamic projection wheel 3 rotates, these different patterns will enter the light path of the light source in sequence, thereby creating a dynamically changing light and shadow effect in the area illuminated by the headlight. This design can not only increase the decorativeness of the headlight, but also be used to convey specific information or warnings, such as projecting a warning sign under special weather conditions, or projecting a welcome pattern when parking.

[0126] Similarly, the different color designs on the color filter 41 enable the headlight to present a rich color change. When the color filter wheel 4 rotates, filters of different colors will enter the light path in sequence, so that the light emitted by the headlight presents a continuously changing color effect. This design not only increases the visual appeal of the headlight, but can also be used for lighting needs in different scenes, or use specific color lights to create an atmosphere in special occasions.

[0127] In this embodiment, the patterns on the image slide 31 may include, but are not limited to, various types such as arrows, boxes, numbers, animal patterns, plant patterns, fruit patterns, portrait patterns, emotion patterns, text patterns, etc. At the same time, the color of the color filter 41 can be selected from one or several of 512 color systems for overlay.

[0128] Embodiment 2

[0129] As Figure 2 shown, this embodiment is basically the same as the previous embodiment, except that:

[0130] The pattern dynamic projection runner 3 includes a sun gear 32, a planet carrier, planet gears 33 arranged from the inside to the outside along the central axis, and an external gear ring fixed on the housing 1;

[0131] The planet gears 33 are rotatably mounted on the planet carrier and meshed between the sun gear 32 and the external gear ring;

[0132] The image slide 31 is mounted on the planet gears 33;

[0133] The first rotation drive source 5 is in transmission connection with the sun gear 32;

[0134] The second rotation drive source 6 is in transmission connection with the planet carrier;

[0135] When the first rotation drive source 5 stops, the second rotation drive source 6 is adapted to drive the planet gears 33 and the image slide 31 on the planet gears 33 to revolve around the sun gear 32 through the planet carrier;

[0136] When the second rotation drive source 6 stops, the first rotation drive source 5 is adapted to drive the planet gears 33 and the image slide 31 on the planet gears 33 to rotate self - rotatably through the sun gear 32.

[0137] In this embodiment, when the first rotation drive source 5 stops and the second rotation drive source 6 works: The second rotation drive source 6 drives the planet carrier to rotate, and the planet carrier drives the planet gears 33 to revolve around the sun gear 32. Since the planet gears 33 are meshed with the fixed external gear ring, the planet gears 33 will rotate self - rotatably during the revolution, and the image slide 31 fixed on the planet gears 33 will perform a compound motion of revolution plus self - rotation accordingly.

[0138] When the second rotation drive source 6 stops and the first rotation drive source 5 works: The first rotation drive source 5 drives the sun gear 32 to rotate, and the sun gear 32 drives the meshed planet gears 33 to rotate self - rotatably. The image slide 31 fixed on the planet gears 33 rotates self - rotatably accordingly. Since the planet carrier is fixed at this time, the planet gears 33 only rotate self - rotatably and do not revolve;

[0139] In this embodiment, an external gear ring is added to form a complete planetary gear mechanism, improving the overall stability. Due to gear meshing, the movement is more precise. Of course, during use, it can be decided whether to add the external gear ring according to specific application requirements, movement effect requirements, and cost considerations.

[0140] The specific embodiments described above further elaborate on the technical problems solved, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
