Technical Field

[0001] The utility model relates to the technical field of automotive switches, in particular to an automotive rotary switch. Background Art

[0002] With the rapid development of automotive electronic technology, more and more electrification functions are integrated in automobiles, and accordingly, users' requirements for the aesthetics and comfort of automotive interior parts are getting higher and higher. Therefore, in order to meet people's pursuit of the sense of technology, operation feeling and appearance of automobiles, each automobile manufacturer is also launching more and more new operation methods and appearance designs.

[0003] Among them, as an important part of the interior parts, the rotary switch has also attracted more and more attention. An existing rotary switch is internally provided with a light-emitting body, and the light-emitting body penetrates out of the shell of the rotary switch, so as to illuminate and light up the indicating symbols arranged on the rotary switch, so as to achieve the function of prompting the rotary switch, and can also become a part of the automotive interior lighting atmosphere, improve the aesthetics of the entire automotive interior, and improve the comfort of the driver and passengers.

[0004] Some light-emitting bodies are colored, such as red, blue or green, etc. When the area of the light guide structure of the switch or the panel is large, generally multiple light-emitting bodies are used; and in order to expand the illumination range, the light guide structure is also increased, and the light is diffused to the required position through the reflecting teeth. Then, when multiple light-emitting bodies diffuse light through the light guide structure, light leakage is likely to occur, and the internal structure of the switch is limited, and multiple light guide structures cannot be arranged. Summary of the Invention

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides an automotive rotary switch, with a notch arranged on the light guide body, so that light does not leak between the light-emitting bodies, thereby controlling multi-color light sources.

[0006] The technical solution of the utility model: An automotive rotary switch includes a shell, a rotary bracket arranged in the shell, and a circuit board. The circuit board is provided with a first light-emitting body and a second light-emitting body. A light guide ring is arranged on the outer periphery of the rotary bracket in the shell. The light guide ring is provided with a notch to form a first light guide area and a second light guide area. Reflecting teeth are arranged on the lower end surfaces of the two light guide areas. One end of the first light guide area far away from the notch is provided with a first light incident column, and the first light incident column corresponds to the first light-emitting body. One end of the second light guide area far away from the notch is provided with a second light incident column, and the second light incident column corresponds to the second light-emitting body. A partition is arranged on the shell between the two light incident columns. The shell is provided with a first light transmission area and a second light transmission area. The first light transmission area is arranged opposite to the first light guide area, and the second light transmission area is arranged opposite to the second light guide area.

[0007] With the above technical solution, the lights emitted by the first light-emitting body and the second light-emitting body respectively enter through the first light-incident column and the second light-incident column, and are evenly diffused to the corresponding light guide areas, and finally pass through the light-transmitting areas of the housing. Due to the arrangement of the notch and the partition, there will be no light leakage between the lights of the two light-emitting bodies on the light guide ring, so that the multi-color light source can be controlled.

[0008] A further setting of the present utility model: on the inner top wall of the housing, a first light-shielding block and a second light-shielding block are relatively provided, the first light-shielding block corresponds to the notch position, and the second light-shielding block corresponds to the partition.

The vertical part is vertically arranged above the light-emitting body, and the arc part is located between the vertical part and the light guide area.

[0013] With the above further further setting, the light emitted by the light-emitting body first enters the vertical part vertically upward, and then enters the arc part and then enters the light guide area, and the light guide effect is good.

[0014] A further further setting of the present utility model: the housing includes a separately provided upper shell and a lower shell. The first light-transmitting area and the second light-transmitting area are provided on the upper shell. The lower shell is provided with an annular boss and a receiving groove. The light guide ring is located on the annular boss. The partition is located in the receiving groove and divides the receiving groove into a first receiving area and a second receiving area. The first light-incident column is located in the first receiving area, the second light-incident column is located in the second receiving area, and arc-shaped surfaces are provided at the upper ends of the first receiving area and the second receiving area corresponding to the arc parts of the light-incident columns.

[0015] With the above further further setting, the installation is convenient. After the light guide ring is installed on the annular boss, the upper shell is then covered outside the light guide ring. The upper shell and the lower shell are connected by a buckle. The arc-shaped surface setting makes the arc part more fitting. The partition divides the receiving groove into areas to avoid light leakage.

[0016] A further further setting of the present utility model: on the inner side walls of the first receiving area and the second receiving area, relatively arranged first positioning members and second positioning members are provided. The two positioning members are located on both sides of the light-incident column and are in contact with the light-incident column.
