DETAILED DESCRIPTION
[0037] In order to make the person skilled in the art better understand the technical scheme of the utility model, the handle of the combined switch of the vehicle gear lever will be introduced and explained in detail below in combination with the drawings and specific embodiments.
[0038] The utility model provides a kind of handle of the combined switch of the vehicle gear lever, combines Figure 1 、 Figure 2 、 Figure 3As shown, the handle of the gear combination switch for vehicle includes a shell 1, a PCBA board 2, a light guide body 3 and the like. The PCBA board 2 and the light guide body 3 are installed in the shell 1. The PCBA board 2 and the light guide body 3 are matched with each other. Only one PCBA board 2 and one light guide body 3 need to be arranged in the shell 1.
[0039] The front surface of the shell 1 is provided with a cursor display area. Figure 1 As shown, the cursor display area of the shell 1 is provided with four gear cursors PRND and a triangular cursor. The letter cursor and the graphic cursor are made of transparent material. The light in the handle can be emitted from the cursors. The marking information of the cursors can also be other contents.
[0040] The light emitting surface of the light guide body 3 faces the cursor display area. The light emitting surface of the light guide body 3 faces the cursor display area. The light guide body 3 is made of optical grade acrylic / PC plate material. When the light is emitted to each light guide point, the reflected light is diffused to each angle, and then the reflection condition is destroyed to be emitted from the front surface of the light guide body. The light guide body 3 uniformly distributes the point light source emitted by the lamp bead 21. The emitted light is a light source, which makes the light distribution more uniform and provides illumination for the multiple cursors of the cursor display area.
[0041] The lamp bead 21 is installed on the PCBA board 2. The PCBA board 2 supplies power for the lamp bead 21. The lamp bead 21 is used for emitting light. The lamp bead 21 can be an LED lamp. The light entrance surface arranged on the side wall of the light guide body 3 faces the lamp bead 21. The light emitted by the lamp bead 21 enters the light entrance surface of the light guide body 3 first. The light entrance surface and the light emitting surface of the light guide body 3 are arranged perpendicularly. The surface of the PCBA board 2 is perpendicular to the light emitting surface of the light guide body 3.
[0042] In addition to the lamp bead 21 arranged on the PCBA board 2, the end of the shell 1 is provided with a parking button 4. The parking button 4 is partially exposed to the shell 1. The parking button 4 is used for realizing the switching of the parking gear. When the parking button 4 is pressed, the related devices on the PCBA board 2 are triggered.
[0043] The handle of the gear combination switch for vehicle only needs to be provided with one PCBA board and one light guide body. An additional PCBA board is not needed for arranging the lamp bead. The cost of one PCBA board is saved, which helps to reduce the cost of the whole handle.
[0044] On the basis of the above scheme, in combination with Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, the thickening boss 31 is arranged at the light inlet surface of the light guide body 3, that is, the thickness of the region near the light inlet surface close to the lamp bead 21 is greater than the thickness of other regions of the light guide body 3, so that more light enters the light guide body 3 in the thickness direction. The thickness of other positions of the light guide body 3 is small, which can save materials and does not occupy too much space.
[0045] If there is no thickening boss 31, part of the light directly jumps over the light guide body 3 and emits forward, which can form a bright area at the front position. By arranging the thickening boss 31, the part of the light is directly changed, and some light is re-introduced into the light guide body 3, so that the overall brightness is improved. That is, the thickening boss 31 intercepts the light above the LED on one hand, reduces the problem of bright spots formed by the direct LED light on the panel, and on the other hand, increases the part of the light entering the light guide strip, and improves the overall brightness of the light guide body.
[0046] As shown in Figure 5 , Figure 7 , the light inlet surface of the light guide body 3 is a cylindrical surface, the lamp bead 21 is arranged at the center position of the cylindrical surface, the distance between each position of the light inlet surface and the lamp bead 21 is substantially equal, the light uniformly irradiates the light inlet surface, and the light reaches the light inlet surface in a vertical direction, so that the light uniformly enters the light guide body 3.
[0047] The side of the thickening boss 31 facing the light outlet surface is higher than the light guide body 3, and the opposite side is flush with the light guide body 3; as shown in Figure 5 , Figure 8 , the light guide body 3 is a plate with a certain thickness as a whole, the light outlet surface is the front surface, the surface away from the light outlet surface is the back surface, the back surface of the thickening boss 31 is flush with the back surface of the light guide body 3, and the front surface of the thickening boss 31 is higher than the front surface of the light guide body 3, so that the structure of the front surface is protruded, and the back surface is relatively flat, which can avoid interference with the arrangement of the structure below.
[0048] As shown in Figure 4 , the edges of the entire thickening boss 31 are arc-shaped, that is, the inner edge of the thickening boss 31 close to the lamp bead 21 is arc-shaped, and the outer edge of the thickening boss 31 away from the lamp bead 21 is arc-shaped.
[0049] A chamfer is arranged between the thickening boss 31 and the light outlet surface of the light guide body 3, that is, an inclined smooth transition is formed between the part of the thickening boss 31 protruding upward and the light outlet surface of the light guide body 3, and the transition surface forms a conical surface, so that the light in the thickening boss 31 can be guided to the main part of the light guide body 3, and the light directly emitted outward from the thickening boss 31 is reduced.
[0050] As shown in Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the structure of the light-emitting surface of the light guide 3 is shown, the light-emitting surface of the light guide 3 is provided with a plurality of concentric circular uniform light grooves 32, the uniform light grooves 32 are circular arc grooves opened in the front surface of the light guide 3, and the circular arc takes the lamp bead 21 as the center. Each uniform light groove 32 is uniformly distributed at equal intervals, and the interval of each uniform light groove 32 can be opened at equal intervals. There is a blank area between the uniform light groove 32 and the thickening boss 31. From the first uniform light groove 32, a plurality of thickening bosses 31 are uniformly distributed outward. The uniform light groove 32 can make the light form a more uniform distribution and emit upward to illuminate the cursor.

The light collecting groove 33 is a groove provided on the back surface of the light guide 3, and the light collecting groove 33 is a straight line-shaped parallel groove. Since only a few cursors are used for actual light emission, the area of the light guide 3 must be larger than the occupied area of the cursor. By providing the light collecting groove 33, the light is concentrated and distributed on the back surface of each cursor. A group of light collecting grooves 33 form a rectangular area, and the parallel straight grooves are arranged in the rectangular area.
[0052] In combination Figure 10 , Figure 11 As shown, the light collecting groove 33 is provided with at least two depths, that is, the depths of some grooves are small, and the depths of some grooves are large; the depth of the area with high brightness is small, and the depth of the area with low brightness is large. One light collecting groove 33 can be located on the back surface of a plurality of cursors, and a larger depth can be provided at the position opposite to the cursor, and a smaller depth can be provided at the position between the cursors.
[0053] In combination Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the back surface of the light guide 3 is provided with parallel straight reflection grooves 34, the reflection grooves 34 are perpendicular to the direction of the light, and the straight line direction of the reflection grooves 34 is different from the straight line direction of the light collecting grooves 33. The reflection grooves 34 are provided at the edge position of the back surface of the light guide 3, and the reflection grooves 34 are designed as inclined grooves. Its main function is to increase the reflection of light and enhance the problem of insufficient brightness in the area.
[0054] In combination Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 11 , Figure 12 ,Figure 13 As shown, the back of the light guide 3 is away from the light-in surface position set cut angle 35, cut angle 35 is located in the edge of the light guide 3, between the back and the sidewall of the light guide 3. Cut angle 35 forms a wedge-shaped notch on the light guide 3, which can cut angle 35 make the corner brightness away from the light source is higher.
[0055] The front of the light guide 3 is provided with a parallel straight partial light adjusting groove 36, the partial light adjusting groove 36 is formed by several straight grooves extending parallel to each other, which constitutes a rectangular area, and the partial light adjusting groove 36 is arranged on the light-out side of the light guide 3. The partial light adjusting groove 36 is independent of the light uniformizing groove 32, and the partial light adjusting groove 36 can form an intersection area with the light uniformizing groove 32. The depth of the partial light adjusting groove 36 is smaller than that of the light uniformizing groove 32, and the partial light adjusting groove 36 is opened in the area with lower brightness, so as to improve the light-out brightness.
