Description

Technical Field

[0001] The utility model relates to the technical field of luminous vehicle logos, and particularly refers to a luminous vehicle logo that realizes high-brightness display. Background Art

[0002] With the gradual popularization of new energy vehicles and the strong support of the country for the new energy vehicle market, the penetration rate of new energy vehicles is getting higher and higher. Major traditional car manufacturers and new power vehicle manufacturing enterprises have accelerated their layout of the new energy industry chain; in order to showcase and promote their new energy vehicle models, most current new energy vehicles are equipped with luminous vehicle logo products as standard to enhance market heat and increase market attention.

[0003] In the prior art, a luminous vehicle logo usually includes a light-transmitting cover, a light homogenizing plate, a light guide plate, an LED lamp board, and a fixed base. Among them, the light-transmitting cover and the fixed base enclose an installation cavity, and the LED lamp board, the light guide plate, and the light homogenizing plate are all arranged in this installation cavity. The light emitted by the LED lamp board passes through the light guide plate, the light homogenizing plate, and the light-transmitting cover in sequence and irradiates outside the light-transmitting cover. In order to achieve an electroplated luminous effect, the light-transmitting cover needs to be processed by a coating process, resulting in a light transmittance of only about 10% for the light-transmitting cover. When a vehicle logo with higher brightness is required, it can only increase the energy consumption of the LED lamp, but this will cause heat out of control and also affect the endurance of new energy vehicles. It is relatively difficult to achieve high-brightness display, and the light transmittance of the light-transmitting cover needs to be adjusted repeatedly during molding to obtain a light-transmitting cover that meets the requirements. Summary of the Invention

[0004] The utility model is made in consideration of the foregoing problems. The purpose of the utility model is to provide a luminous vehicle logo that realizes high-brightness display, which can achieve high-brightness display of the luminous vehicle logo and has low energy consumption.

[0005] To achieve the above purpose, the utility model provides a luminous vehicle logo that realizes high-brightness display, including a light-transmitting cover, a base, a circuit board, and a light guide plate. The light-transmitting cover and the base enclose an installation cavity. The circuit board and the light guide plate are both arranged in the installation cavity, and a light source is provided on one side of the circuit board close to the light-transmitting cover. The light guide plate is located between the light-transmitting cover and the circuit board.

[0006] The light-transmitting cover includes a transparent layer and an adjustment layer. The adjustment layer is located inside the transparent layer and is used to adjust the light transmittance of the light-transmitting cover.

[0007] For the above-mentioned luminous vehicle logo that realizes high-brightness display, the adjustment layer is set as an electrochromic glass film. There is an interlayer inside the transparent layer, and the electrochromic glass film is embedded in the interlayer.

[0008] As described above, a luminous car logo for realizing high-brightness display, wherein the adjustment layer and the transparent layer are integrally formed, and the adjustment layer is connected to the circuit board through an electric wire.

[0009] As described above, a luminous car logo for realizing high-brightness display, wherein the light guide plate is provided with optical patterns to enhance the optical utilization rate of the light guide plate.

[0010] The utility model has the following beneficial effects: The light-transmitting cover includes a transparent layer and an adjustment layer, and the adjustment layer is an electrochromic glass film, which is electrically connected to the circuit board. Different voltages of current can be applied to the electrochromic glass film through the circuit board to adjust the light transmittance of the electrochromic glass film, thereby improving its light transmittance. Without changing the power of the light source, high-brightness display of the car logo can be achieved. At the same time, optical patterns are also provided on the light guide plate to enhance the optical utilization rate of the light guide plate and further improve the high-brightness display effect.

[0014] The following are specific embodiments of the present invention in combination with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0015] As Figure 1 shown, a luminous car logo for realizing high-brightness display includes a light-transmitting cover 1, a base 2, a circuit board 3, and a light guide plate 4. The light-transmitting cover 1 and the base 2 enclose an installation cavity. The circuit board 3 and the light guide plate 4 are both arranged in the installation cavity. A light source 7 is provided on one side of the circuit board 3 close to the light-transmitting cover 1. The light guide plate 4 is located between the light-transmitting cover 1 and the circuit board 3. After the light source 7 emits light, the light passes through the light guide plate 4 and the light-transmitting cover 1 in sequence and is emitted. Specific patterns are provided on the light-transmitting cover 1 to form a luminous car logo. The light-transmitting cover 1 includes a transparent layer 5 and an adjustment layer 6. The adjustment layer 6 is located inside the transparent layer 5 and is used to adjust the light transmittance of the light-transmitting cover 1. Since all light needs to pass through the adjustment layer 6, after adjusting its light transmittance, the brightness of the emitted light can be changed. When high-brightness light is required, the light transmittance of the light-transmitting cover 1 can be adjusted higher. Therefore, high-brightness display of the car logo can be achieved without changing the power of the light source 7, and the energy consumption is low.

[0016] In order to adjust the light transmittance of the entire light-transmitting cover 1 by the adjustment layer 6, the adjustment layer 6 is set as an electrochromic glass diaphragm. A sandwich layer is provided in the transparent layer 5, and the electrochromic glass diaphragm is embedded in the sandwich layer. During the molding process, the adjustment layer 6 and the transparent layer 5 can be integrally molded by injection molding. After molding, processes such as painting and engraving are carried out. At the same time, the electrochromic glass diaphragm is also electrically connected to the circuit board 3 through wires. Then, power can be supplied to the electrochromic glass diaphragm through the circuit board 3. When the voltage of the electrochromic glass diaphragm is changed, the optical properties of the electrochromic glass diaphragm can be changed, including the light transmittance, thereby affecting the overall light transmittance of the light-transmitting cover 1 to achieve adjustment.

[0017] At the same time, an optical pattern 8 is provided on the light guide plate 4 to enhance the optical utilization rate of the light guide plate 4 and further improve the high-brightness display effect.
