Because the luminous sign is directly arranged in the center of the steering wheel, if the light generated by the luminous sign is too strong, certain interference can be caused to eyes of a driver. According to the invention, the light emitting parts 4 are arranged in the above manner, the light emitting parts 4 are positioned below the cover bodies, under the blocking of the cover bodies, the light generated by the light emitting parts 4 cannot be directly transmitted out from the light transmitting surface on the light transmitting module 1, but is scattered by the light guide block 5 and is emitted out from the light transmitting surface on the light transmitting module 1 after passing through the light homogenizing sheet 7, so that the emitted light is softer, the irritation and interference to eyes of a driver are reduced, and the driving safety is ensured.

As shown in fig. 10 and 11, the positions and the number of the light emitting elements 4 are set according to the actual shape of the protruding portion, so that each light emitting element 4 can uniformly radiate to each light emitting area, the light emitting amount of each position on the protruding portion is uniform, and no light emitting effect is good when a certain position is particularly bright or a certain area is particularly dark. Fig. 10 shows an effect of the present invention in actual light emission, and as can be seen from fig. 10, the light emission luminance in each region is relatively uniform. Eight sampling points in #001- #008 different positions are arranged in different light-emitting areas in fig. 10, backlight brightness of the eight sampling points in different positions is tested, a data table in fig. 11 shows backlight data of each sampling point, and as a result, the difference of the backlight data of each sampling point is smaller, so that the overall light-emitting brightness of the light-emitting target is uniform.

The light guide block 5 is provided with a plurality of pits 11 on one side close to the PCB 3, and the pits 11 are round. Wherein the grooves 21 are arranged in a rectangular array on the light guide block 5, and the pitch between adjacent pits 11 is 1.2-1.5 times the diameter of the pits 11. By providing a circular pit 11 on one side of the light guide block 5, the pit 11 can function as follows: because the air bag is arranged below the center of the steering wheel, the luminous mark is arranged above the air bag, and the main substance of the air bag for generating gas is sodium azide, the sodium azide needs to be protected from light; the arrangement of the concave pits 11 can improve the reflection amount of light on the side of the light guide block 5 and reduce the leakage amount of light from the side close to the air bag, thus reducing the influence on the air bag. And the arrangement of the pits, when the uniformity of light emission is regulated, and the light irradiates one side of the pits, the pits reflect the light in all directions (similar to the effect of diffuse reflection) due to the existence of the pits, so that the uniformity of light emission is improved.

Secondly, because the air bag is arranged below the luminous mark, certain requirements are imposed on the weight of the luminous mark, and the weight of the luminous mark should be as light as possible. The pit 11 reduces the usage amount of the material of the light guide block 5, thereby reducing the weight of the light guide block 5, further reducing the overall weight of the whole luminous mark and reducing the influence on the safety air bag.

The PCB 3 is connected with the central control of the automobile, the luminous brightness of the luminous piece 4 is adjusted through the central control of the automobile, and the luminous mode of the luminous piece 4 is adjusted, so that personalized setting of luminous effect is realized. The lighting mode of the lighting element 4 can be set through the automobile central control according to actual needs, so that the lighting effect of the lighting element can be linked with other atmosphere lamps in the automobile, and the lighting effect of the lighting element is more harmonious and unified with the lighting effect of other decorative lamps in the automobile.

The invention has the following advantages:

1. The luminous effect of the luminous cursor can be controlled by being connected with the automobile central control, the atmosphere in the automobile can be effectively improved, and the personalized requirements of consumers are met.

2. The light generated by the light emitting piece 4 is not directly transmitted out of the light transmitting surface on the light transmitting module 1, but is scattered by the light guide block 5 and is emitted out of the light transmitting surface on the light transmitting module 1 after passing through the light homogenizing sheet 7, so that the emitted light is softer, the irritation and interference to eyes of a driver are reduced, and the driving safety is ensured; meanwhile, each luminous element 4 can uniformly radiate to each luminous area, so that the luminous quantity of each position on the convex part is uniform, and the condition that a certain position is particularly bright or a certain area is particularly dark does not exist, so that the luminous effect is good.
