Description

Technical Field

[0001] This utility model relates to an automotive lighting fixture with dynamic lighting effects, belonging to the field of automotive lighting technology. Background Technology

[0002] Currently, most traffic lights achieve dynamic illumination by sequentially lighting one or more LEDs through a single light-emitting window, which can achieve a good lighting effect. However, stacking a large number of LEDs increases the number of driver chips, raises the overall power of the light, and also increases the size and structural complexity of the corresponding optical components. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automotive lamp with dynamic lighting effects. The dynamic lighting effect of sequential window lighting is achieved through mechanical transmission, thereby reducing the overall power consumption of the lamp and lowering the manufacturing cost.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An automotive lighting fixture with dynamic lighting effects includes a power unit, a drive shaft, a first bracket, a second bracket, and a trim ring;

[0006] The power unit drives the transmission shaft to rotate, the transmission shaft is rotatably connected to the second bracket, a gear is fixed on the transmission shaft, and a rack that meshes with the gear is provided on the first bracket;

[0007] The second bracket is slidably connected to the first bracket, and a light panel is provided on the second bracket, with a light source provided on the light panel;

[0008] The decorative ring has multiple light-transmitting areas, and the second bracket drives the light source to pass through the multiple light-transmitting areas on the decorative ring in sequence.

[0009] Furthermore, the power unit is an electric motor, and the transmission shaft is connected to the motor shaft of the electric motor.

[0010] Furthermore, the first bracket is provided with sliding grooves on its upper and lower sides respectively.

[0011] Furthermore, the upper and lower ends of the second bracket are respectively provided with limiting ribs that slide in conjunction with the sliding groove.

[0012] Furthermore, the rack is disposed between the upper and lower sliding grooves of the first bracket.

[0013] Furthermore, a non-transparent area is provided between every two light-transmitting areas.

[0014] Furthermore, the second bracket is provided with studs, and the lamp plate is fixed on the studs.

[0015] By adopting the above technical solution, this utility model uses a motor and drive shaft to drive a second bracket to slide on a first bracket via the meshing of gears and racks. The second bracket then moves the light source. Since the decorative ring is mounted on the vehicle body and its position is fixed, the light source sequentially passes through multiple light-transmitting areas on the decorative ring, thus achieving a dynamic lighting effect of sequentially illuminating the windows. This utility model achieves a dynamic lighting effect of sequentially illuminating windows through simple mechanical transmission, eliminating the need for a large number of LEDs and driver chips, resulting in lower overall power consumption, a simpler structure, and lower manufacturing costs.

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] like Figures 1-4 As shown, this embodiment provides an automotive lighting fixture with dynamic lighting effects, comprising a power unit 1, a drive shaft 12, a first bracket 2, a second bracket 4, and a decorative ring 3. The power unit 1 and the drive shaft 12 drive the second bracket 4 to slide on the first bracket 2. A light source 42 is mounted on the second bracket 4. The decorative ring 3 has multiple light-transmitting areas 32 arranged at intervals. The second bracket 4 drives the light source 42 to pass sequentially through the multiple light-transmitting areas 32 on the decorative ring 3, thereby creating the effect of sequentially illuminating windows.

[0022] like Figure 1 , 3 As shown, in this embodiment, the power device 1 is a motor, and the transmission shaft 12 is connected to the motor shaft, driving the transmission shaft 12 to rotate. The transmission shaft 12 is rotatably connected to the second bracket 4 via bearings. A gear 11 is fixed on the transmission shaft 12, and a rack 21 that meshes with the gear 11 is provided on the first bracket 2. Figure 1As shown, the first bracket 2 has sliding grooves 22 on its upper and lower sides, and a rack 21 is disposed between the two sliding grooves 22 of the first bracket 2. The second bracket 4 has limiting ribs 43 at its upper and lower ends that slide in cooperation with the sliding grooves 22. After the drive shaft 12 rotates, it drives the gear 11 to rotate, and then the gear 11 meshes with the rack 21, thereby causing the second bracket 4 to slide on the first bracket 2.

[0023] like Figure 3 , 4 As shown, in this embodiment, a stud 44 is provided on the second bracket 4, and the lamp plate 41 is fixed on the stud 44 by screws. A light source 42 is installed on the lamp plate 41, and the light source 42 is moved by the second bracket 4.

[0024] like Figure 1 , 4 As shown, the decorative ring 3 in this embodiment is provided with multiple light-transmitting areas 32, and a non-light-transmitting area 31 is provided between every two light-transmitting areas 32. Each light-transmitting area 32 is a light-transmitting window. Finally, the second bracket 4 drives the light source 42 to pass through the multiple light-transmitting areas 32 on the decorative ring 3 in sequence, so as to achieve a dynamic lighting effect of lighting up the windows in sequence.
