Description

Technical Field

[0001] This utility model relates to the field of electric vehicle or motorcycle control switch technology, specifically a compact combination switch with backlight. Background Technology

[0002] Combination switches are the control center on electric vehicles and motorcycles, and a key module for human-machine interaction. In low-light or nighttime environments, backlighting is typically required to facilitate user identification of switch locations and function indicators. However, existing backlighting solutions require separate brackets or fixing structures for mounting the light-emitting elements, leading to a complex overall structure, increased number of components, higher manufacturing costs, and greater difficulty in handle installation. Therefore, providing backlighting for combination switches while simplifying the structure is a technical problem that needs to be solved in this field. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a compact combination switch with backlight, so as to realize the backlight function while simplifying the structure.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A compact combination switch with backlighting, comprising: shell; A base is installed in the housing, and the base is provided with a mounting groove; An operating component includes a mounting base and an operating element, the operating element being mounted on the mounting base and extending out of the housing, the mounting base being installed in a mounting groove; A circuit board is disposed on the mounting base, and the circuit board has a hollow structure corresponding to the position of the operating component; An indicator is mounted on the housing, the indicator having an indicator portion, and the indicator being light-transmitting at least at the position corresponding to the indicator portion; A light-emitting element is disposed on the circuit board and is positioned at least corresponding to the position of the indicator portion; The indicator is pressed against the circuit board to press the circuit board against the mounting base.

[0005] As a further improvement of this utility model, the indicator is provided with a surrounding edge on the side facing the circuit board, and the surrounding edge surrounds all the light-emitting elements corresponding to the indicator portion.

[0006] As a further improvement of this utility model, the surrounding edge is formed by the indicator extending toward the surface of the circuit board in the direction of the circuit board.

[0007] As a further improvement of this utility model, the indicator is provided with a positioning post corresponding to the circuit board, and positioning holes are provided on the circuit board and the mounting base at positions corresponding to the positioning post, with the positioning post passing through the positioning holes on the circuit board and the mounting base.

[0008] As a further improvement of this utility model, the indicator is made of a light-transmitting material, and the surface other than the indicator part is covered with an opaque coating.

[0009] As a further improvement of this utility model, the indicator is provided with a hollow structure corresponding to the position of the operating member, so that the operating member can extend out. There is a gap between the hollow structure of the indicator and the operating member, and the light source of the light-emitting element leaks out from the gap.

[0010] As a further improvement of this utility model, the operating component is detachably snapped into the mounting groove of the base by a snap-fit.

[0011] The beneficial effects of this utility model are that by pressing the indicator onto the circuit board to press the circuit board onto the mounting base, the indicator can simultaneously perform the dual functions of light transmission indication and circuit board pressing and fixing, eliminating the need for a separate circuit board fastening structure; at the same time, the circuit board has a hollow structure corresponding to the position of the operating component, allowing the operating component to extend through the circuit board, realizing the coexistence of the operating component and the circuit board in a compact space, resulting in a compact overall structure, fewer parts, and simple assembly.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-5 As shown, a compact combination switch with backlighting according to this embodiment includes: Outer shell 1; Base 2 is installed in the outer casing 1, and base 2 is provided with mounting groove 21; The operating component 3 includes a mounting base 31 and an operating element 32. The operating element 32 is mounted on the mounting base 31 and extends out of the outer shell 1. The mounting base 31 is installed in the mounting groove 21. Circuit board 4 is mounted on mounting base 31, and the circuit board 4 has a hollow structure corresponding to the position of operating component 32. An indicator 5 is mounted on the housing 1. The indicator 5 has an indicator part 51. The indicator 5 is light-transmitting at least at the position corresponding to the indicator part 51. The light-emitting element 41 is disposed on the circuit board 4 and is disposed at least at the position corresponding to the indicator part 51; The indicator 5 is pressed against the circuit board 4 to press the circuit board 4 against the mounting base 31.

[0016] Circuit board 4 is mounted on mounting base 31. A cutout structure is provided on circuit board 4 corresponding to the position of operating component 32, allowing operating component 32 to pass through circuit board 4. This achieves the coexistence of operating component 32 and circuit board 4 without increasing the overall thickness. Light-emitting element 41 is mounted on circuit board 4, corresponding to the indicator portion 51 on indicator 5. The light emitted by light-emitting element 41 passes through the light-transmitting indicator portion 51 of indicator 5, realizing the backlight indicator function. After indicator 5 is mounted on housing 1, indicator 5 is pressed against circuit board 4, pressing circuit board 4 against mounting base 31. This eliminates the need for a separate circuit board 4 fastening structure, reduces the number of parts, and simplifies the assembly process. Because the structure uses indicator 5 as both the light-transmitting indicator 5 and the circuit board 4 clamping component, it solves the problem of complex structure and difficult installation caused by the need for a separate light-emitting component bracket for backlight function in existing technologies. Moreover, this solution is more suitable for integrated designs, making installation more convenient.

[0017] In order to concentrate the light source of the light-emitting element 41, in an optional embodiment, a surrounding edge 52 is provided on the side of the indicator 5 facing the circuit board 4, and the surrounding edge 52 surrounds all the light-emitting elements 41 corresponding to the indicator part 51.

[0018] The rim 52 extends from the surface of the indicator 5 toward the circuit board 4, physically surrounding the light-emitting element 41 and blocking light from diffusing in all directions. This allows the light from the light-emitting element 41 to more concentratedly illuminate the indicator 51, reducing light leakage and improving indicator clarity. The rim 52 is an integral part of the indicator 5, requiring no additional assembly, and its light-blocking effect is reliable. Because the rim 52 concentrates the light from the light-emitting element 41 into the light-transmitting area of ​​the indicator 51, it solves the problem of blurred indication caused by stray light around the indicator.

[0019] To facilitate the positioning of the indicator 5 relative to the circuit board 4 and the mounting base 31, further optimization can be achieved by selecting the following methods. The indicator 5 is provided with a positioning post 53 corresponding to the circuit board 4. Positioning holes 6 are provided on the circuit board 4 and the mounting base 31 at the positions corresponding to the positioning post 53. The positioning post 53 passes through the positioning holes 6 on the circuit board 4 and the mounting base 31.

[0020] During assembly, the positioning pin 53 passes through the positioning holes 6 of the circuit board 4 and the mounting base 31 in sequence to achieve precise positioning of the three-layer components of the indicator 5, the circuit board 4 and the mounting base 31, ensuring that the indicator part 51 is aligned with the light-emitting element 41.

[0021] To achieve a more accurate indication effect, in some options, the indicator 5 is made of a light-transmitting material, and the surface except for the indicator part 51 is covered with an opaque coating.

[0022] The light from the light-emitting element 41 is only emitted from the indicator part 51, while the rest is blocked by the coating. This ensures that the backlight is only displayed at the position of the indicator part 51, preventing the area outside the indicator light from emitting light and improving the accuracy and aesthetics of the indication.

[0023] In order to provide illumination around the operating component 32 and facilitate identification and operation of the operating component 32 at night, the indicator 5 is further provided with a hollow structure corresponding to the position of the operating component 32, so that the operating component 32 can extend out. There is a gap 7 between the hollow structure of the indicator 5 and the operating component 32, and the light source of the light-emitting element 41 leaks out from the gap 7.

[0024] The light from the light-emitting element 41 shines through the gap 7 from around the operating component 32, providing ambient lighting for the operating component 32. This makes it easier for users to quickly locate and operate the operating component 32 at night, improving the convenience of nighttime operation. Because the light source of the light-emitting element 41 shines through the gap 7 to the area around the operating component 32, the problem of the operating component 32 being difficult to identify at night can be solved without the need for additional light sources.

[0025] To facilitate the installation and removal of the operating component 3, in one specific structure, the operating component 3 is detachably snapped into the mounting slot 21 of the base 2 by a snap-fit.

[0026] The snap-fit ​​design enables quick and easy installation of the operating component 3 without the need for tools, improving assembly efficiency and facilitating subsequent maintenance and replacement. This solves the problem of requiring tools or cumbersome procedures for assembling the operating component 3.

[0027] The above implementation methods will be combined below to provide a complete description of the working principle of the overall solution.

[0028] In this combination switch, the base 2 is installed inside the housing 1. The operating component 3 is detachably snapped into the mounting slot 21 of the base 2 via a snap-fit. The operating component 3 includes a mounting base 31 and an operating element 32, which extends out of the housing 1 for operation. The circuit board 4 is mounted on the mounting base 31, and the light-emitting element 41 is located on the circuit board 4 corresponding to the position of the indicator 51. The indicator 5 is mounted on the housing 1, and the precise positioning of the three components—indicator 5, circuit board 4, and mounting base 31—is achieved by using positioning pins 53 passing through positioning holes 6 in the circuit board 4 and mounting base 31. The indicator 5 is pressed against the circuit board 4, pressing the circuit board 4 against the mounting base 31, eliminating the need for a separate fastening structure for the circuit board 4. The surrounding edge 52 extends from the surface of the indicator 5 toward the circuit board 4, surrounding all the light-emitting elements 41 to concentrate the light source. The indicator 5 is made of a light-transmitting material, except that the outer surface of the indicator 51 is covered with an opaque coating, allowing light to pass through only from the indicator 51. The circuit board 4 and the indicator 5 are provided with a hollow structure at the position corresponding to the operation component 32. The operation component 32 extends through the hollow structure, and the gap 7 between the hollow structure and the operation component 32 allows the light from the light-emitting element 41 to leak out, thereby realizing the surrounding illumination of the operation component 32.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
