Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automotive gear shift panels, and particularly to a light guiding structure for an automotive gear shift panel. Background Art
[0002] In traditional automobiles, the automatic transmission shift mechanism mostly relies on a physical shift lever or knob, as well as gear position indicator lights on the instrument panel or center console. These designs have limitations in terms of operation intuitiveness and user experience. Especially during night driving or in complex operation scenarios, the driver may need to divert attention to confirm the current gear position, which is not convenient for the driver to immediately know the vehicle gear state.
[0003] Therefore, the existing solution is to divide the in-vehicle gear module into two parts, namely the instrument panel and the gear display panel, to facilitate the driver to observe the gear information. Currently, the light guiding structure of the automotive gear shift panel lights up the characters by direct light irradiation from the light source. When the light source irradiates directly, its light emitting angle is often larger than the light transmitting area, forming a light source loss area on both sides of the light transmitting area, resulting in low brightness of the light on the gear characters. In the case of strong external light, it is very difficult to display the automotive gear. Summary of the Utility Model
[0004] Based on this, in view of the above technical problems, it is necessary to provide a light guiding structure for an automotive gear shift panel. The direct light is refracted by a light guiding component, and the scattered light is reflected onto a light guide plate by a mirror oil film. Then, the light is collected by the light guide plate and evenly emitted to irradiate the corresponding gear character cover plate. The brightness of the characters is controlled by an LED lamp. Therefore, the brightness of the characters is not the same as that of the liquid crystal screen, forming a brightness difference to guide the driver's line of sight and more clearly know the current gear position.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

One side of the heat dissipation plate penetrates through the plastic housing and is connected to the heat dissipation plate, and the other side of the heat dissipation plate penetrates through the housing and extends into the thermal conductive silica gel.
[0011] Further, a plurality of mounting holes are provided on the side of the top case away from the groove. The number of the plurality of mounting holes is equal to and corresponds to the number of the plurality of grooves.
[0012] Further, a PCB board is fixedly installed on one side of the mounting hole, and a plurality of LED lights are fixedly installed on one side of the PCB board.
[0013] Further, the number of the plurality of LED lights matches the number of the mounting holes, and one end of each LED light extends into the groove.
[0014] Further, the LED lights and the light guide plate are on the same plane and correspond to each other, and the size of the light guide plate is larger than that of the LED lights.
[0015] Further, a plurality of heat dissipation fins are fixedly connected to one side of the heat dissipation plate, and a plurality of air flow grooves are provided on opposite sides of the heat dissipation fins.
[0016] Further, the mirror oil film has a highly uniform and bright silver luster, and the light guide plate is arranged in a standard rectangular shape.
[0017] Further, the top case is arranged in a trapezoidal structure, and a gear position character cover plate of different gears is fixedly installed above each groove.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0040] Embodiment 1
[0041] Please refer to Figures 1-3 , a light guide structure of a vehicle gear panel, which includes: a plastic shell 1, with a window opened on one side of the plastic shell 1, a liquid crystal screen 11 is provided on the window, a backlight 12 is provided on one side of the liquid crystal screen 11, and a top shell 13 is provided on the top of the plastic shell 1; a light guide component, which is disposed on the top shell 13 and is used to emit light onto the top shell 13.

The backlight 12 provides light source for the liquid crystal screen 11. Corresponding characters for each gear of the automatic transmission are provided on the top shell 13. After shifting into the corresponding gear, the corresponding characters are illuminated through the light guide component, so that the driver can clearly know the current gear. The liquid crystal screen 11 can be cooled by the heat dissipation component, avoiding the temperature of the liquid crystal screen 11 being too high to affect the smoothness and preventing overheating damage, thereby improving the service life.
[0043] Embodiment 2
[0044] On the basis of Embodiment 1, a plurality of grooves 2 are provided on one side of the top shell 13 at equal intervals. A mirror oil film 21 is sprayed on the inner walls of the plurality of grooves 2. A light guide plate 22 is fixedly connected to one side of the groove 2. A plurality of mounting holes 23 are provided on the side of the top shell 13 away from the groove 2. The number of the plurality of mounting holes 23 is equal to and corresponds to the number of the plurality of grooves 2. A PCB board 24 is fixedly installed on one side of the mounting hole 23. A plurality of LED lights 25 are fixedly installed on one side of the PCB board 24. The LED lights 25 and the light guide plate 22 are on the same plane and correspond to each other. The size of the light guide plate 22 is larger than that of the LED lights 25. The appearance of the mirror oil film 21 presents a highly uniform and bright silver luster. The light guide plate 22 is arranged in a standard rectangular shape. The top shell 13 is arranged in a trapezoidal structure. A gear position character cover plate 14 of different gears is fixedly installed above each groove 2. The number of the plurality of LED lights 25 matches the number of the mounting holes 23. One ends of the LED lights 25 respectively extend into the grooves 2.
[0045] After changing the gear position, the PCB board 24 receives a signal and lights up the LED lights 25 corresponding to the gear position. After the LED lights 25 light up and emit light, the silver mirror oil film 21 can effectively utilize the physical properties of metal particles to achieve a mirror-like reflection effect through the micro-structure arrangement, reflect the light onto the light guide plate 22, converge the light source through the light guide plate 22, and the light guide plate 22 efficiently transmits and uniformly diffuses the light onto the corresponding gear position character cover plate 14. The gear position character cover plate 14 lights up to display the current gear position state, separating the gear position display from the liquid crystal screen 11 for separate display. Compared with the small character reminder on the liquid crystal screen 11, it is more eye-catching and convenient for the driver to observe. The brightness of the characters is controlled by the LED lights 25. Therefore, the brightness of the characters does not need to be consistent with that of the liquid crystal screen 11, forming a brightness difference to guide the driver's line of sight to display the key points, and the mechanism is simple and the price is cheap.
[0046] Embodiment 3
[0047] On the basis of Embodiment 1, a shell 3 is fixedly installed on one side of the backlight 12. A heat-conducting silica gel 31 is provided inside the shell 3. A plurality of heat-conducting plates 32 are fixedly connected to one side of the shell 3 at equal intervals. A heat-dissipating plate 33 is fixedly installed on the non-window side of the plastic shell 1. One side of the heat-conducting plate 32 penetrates through the plastic shell 1 and is connected to the heat-dissipating plate 33, and the other side of the heat-conducting plate 32 penetrates through the shell 3 and extends into the heat-conducting silica gel 31. A plurality of heat-dissipating fins 34 are fixedly connected to one side of the heat-conducting plate 32 at equal intervals. A plurality of air flow grooves 35 are provided on the opposite sides of the heat-dissipating fins 34.
[0048] During the use of the liquid crystal screen 11, a large amount of heat is generated. The generated heat is first transferred by direct contact to the adjacent housing 3. As an intermediary, the housing 3 can initially conduct heat transfer. The heat-conducting silica gel 31 filled inside the housing 3 is a highly efficient heat-conducting medium, which can quickly absorb and transfer the heat transferred by the housing 3, ensuring that the heat energy flows smoothly to the next heat dissipation link. The heat-conducting plate 32 receives the heat in the heat-conducting silica gel 31, and transfers the heat to the heat dissipation plate 33 through the heat-conducting plate 32. The heat is dissipated into the air through the heat dissipation plate 33. When the air flows through the channel between two adjacent heat dissipation fins 33, it will take away the heat on the surface of the heat dissipation fins 33, accelerating the heat dissipation process. The design of the air flow groove 35 helps to form a more effective air duct, improving the heat dissipation efficiency.
[0049] The usage process of the automatic column chromatography device provided by the present utility model is as follows:
[0050] After shifting gears, the PCB board 24 receives a signal and lights up the LED lamp 25 corresponding to the gear. After the LED lamp 25 lights up and emits light, the silver mirror oil film 21 can effectively utilize the physical properties of metal particles to achieve a mirror-like reflection effect through the micro-structure arrangement, reflecting the light onto the light guide plate 22. The light guide plate 22 converges the light source, and the light guide plate 22 efficiently transmits and evenly diffuses the light onto the corresponding gear character cover plate 14. The gear character cover plate 14 lights up to display the current gear state, separating the gear display from the liquid crystal screen 11 for separate display. Compared with the small character reminder on the liquid crystal screen 11, it is more eye-catching and convenient for the driver to observe. The brightness of the characters is controlled by the LED lamp 25, so the brightness of the characters does not need to be the same as that of the liquid crystal screen 11, forming a brightness difference to guide the driver's line of sight to display the key points. Moreover, the mechanism is simple and the price is cheap. During the use of the liquid crystal screen 11, a large amount of heat is generated. The generated heat is first transferred by direct contact to the adjacent housing 3. As an intermediary, the housing 3 can initially conduct heat transfer. The heat-conducting silica gel 31 filled inside the housing 3 is a highly efficient heat-conducting medium, which can quickly absorb and transfer the heat transferred by the housing 3, ensuring that the heat energy flows smoothly to the next heat dissipation link. The heat-conducting plate 32 receives the heat in the heat-conducting silica gel 31, and transfers the heat to the heat dissipation plate 33 through the heat-conducting plate 32. The heat is dissipated into the air through the heat dissipation plate 33. When the air flows through the channel between two adjacent heat dissipation fins 33, it will take away the heat on the surface of the heat dissipation fins 33, accelerating the heat dissipation process. The design of the air flow groove 35 helps to form a more effective air duct, improving the heat dissipation efficiency.
