The non-transparent area 12 can be made into any color by coating treatment.

As shown in Figure 2, it is a structural schematic view of the light guide plate in the prior art, the light guide plate is located at the rear of the front shell, and has a plurality of microprism structures 21 and one or more receiving grooves 22, wherein the microprism structure 21 is used to change the flow of light in the light guide The propagation direction in the light plate 20 is such that the light is emitted from the surface of the light guide plate 20 opposite to the front case 10 . The area formed by the plurality of microprism structures corresponds to the transparent area 11 of the front shell. The accommodating groove is used for accommodating the illuminant; the accommodating groove can be multiple, the number of which is equal to the number of luminous bodies; or one, accommodating multiple luminous bodies in one accommodating groove; preferably there are multiple accommodating grooves.

The liner 30 is disposed behind the light guide plate 20 and has one or more through holes 31 corresponding to the one or more receiving grooves 22 .

The circuit board (not shown in the figure) is arranged behind the backing plate 30 and has one or more luminous bodies, which serve as the light source of the entire motor vehicle logo. One or more illuminants are inserted into one or more receiving grooves 22 through one or more through holes 31 .

As shown in FIG. 2 , the light emitted by the illuminant enters the light guide plate 20 from the sidewall of the receiving groove 22 . In order to highlight the car logo and make the car logo bright, light enters the light guide plate from the side wall of the receiving groove 22 facing the car logo side. The light propagates in the light guide plate, and when it encounters the microprism structure 21, it emits toward the surface of the light guide plate 20 and opposite to the front shell 10, so that a surface luminous effect is formed in the microprism area to illuminate the transparent area 11 of the front shell to make the vehicle The marker glows. However, due to the existence of the accommodation groove 22, part of the light is blocked by the accommodation groove when it propagates to the periphery of the light guide plate, and the part of the periphery of the light guide plate opposite to the accommodation groove emits light darkly, resulting in uneven light emission in the peripheral annular area of the car logo, which affects the visual effect .

The rear case 40 is arranged behind the circuit board, and the rear case 40 is sealingly connected with the front case 10 , and an accommodating space is defined between the rear case and the front case, and the accommodating space accommodates the light guide plate 20 , the backing plate 30 and the circuit board.

The main improvement of the utility model lies in the light guide plate. As shown in Figure 3, the utility model adds a groove 23' to the light guide plate of the existing car logo. Between the transparent areas of the car logo, the groove structure composed of the groove 23' and the receiving groove 22' surrounds the car logo area. When the light emitted by the illuminant propagates in the light guide plate, the groove 23', like the receiving groove 22', blocks part of the light from propagating to the microprism area on the periphery of the light guide plate, thereby reducing the number of microprisms on the periphery of the light guide plate corresponding to the groove. The luminous brightness of the structure makes the luminous brightness of the entire car logo uniform and consistent, making the car logo more beautiful as a whole.

As shown in FIG. 3 , there are also grooves between the plurality of receiving grooves 22 ′, so that the peripheral annular area of the vehicle logo emits light more uniformly. The width of the groove must be set within a reasonable range, specifically between 0.2 mm and 1 mm, and the effect is better.

The reflective material may be a reflective paint coated on the surface or a reflective sheet added to the surface.

The side of the light guide plate 20 ′ can also be an inclined surface, through the refraction of light on the inclined surface, the overall car logo has a more three-dimensional effect, and at the same time, the overall brightness of the car logo is increased.

As shown in FIG. 4, a light-shielding sheet 25" is arranged above the one or more illuminants, which is used to block the light emitted by the illuminants directly from the light guide plate 20" without being refracted by the light guide plate 20" and in contact with the light guide plate 20". The light emitted from the opposite surface of the front shell. This part of the light is irradiated on the non-transparent area of the front shell of the car logo, which will form a light spot on the non-transparent area, which will affect the overall aesthetics of the car logo. Preferably, the light-shielding sheet 25" has reflective material on the side facing the illuminant. The reflective material can reflect the light emitted by the illuminant directly from the non-transparent area of the front shell into the light guide plate without entering the light guide plate 20 ″, so as to improve the utilization rate of light, thereby improving the overall brightness of the vehicle logo.

The transparent area of the front shell of the car logo can be set as a planar structure or a recessed structure, preferably a recessed structure. When the recessed structure emits light, the car logo as a whole has a more three-dimensional effect and improves the visual effect of the car logo.
