Description

Technical Field

[0001] This utility model belongs to the field of vehicle accessories, specifically relating to a switch assembly for motorcycles / electric vehicles and a handlebar switch using the same. Background Technology

[0002] Motorcycles and electric vehicles, as daily modes of transportation, have control systems, especially handlebar switch assemblies, that operate under complex and ever-changing environments. Handlebar switches control various functions such as lights, turn signals, and horns, and typically contain flexible circuit boards, switching elements, and power supply boards. These electronic components are extremely sensitive to moisture, dust, and humid air. When vehicles are driven in rainy weather, washed, or used in high-humidity environments, the switch components are highly susceptible to environmental corrosion. Existing waterproofing solutions primarily focus on sealing the switch housing or the switch button itself; however, the power supply board inside the switch housing and its connector to the flexible circuit board lack effective protection, which affects the overall reliability and lifespan of the switch. Therefore, there is an urgent need for a waterproofing solution that can effectively seal this vulnerable area. Utility Model Content

[0003] In response to this, the present invention provides a switch assembly and a handlebar switch using the same. By optimizing the sealing structure, it precisely solves the waterproof and dustproof problems of the power adapter board and its connector with the flexible circuit board, thereby improving the protection level and thus enhancing the reliability and service life of the handlebar switch in complex environments.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] In a first aspect, this utility model provides a high-protection-level switch assembly, including a mounting bracket, a flexible circuit board, a switching element, and a power adapter board; the switching element is mounted on the flexible circuit board, and the flexible circuit board is electrically connected to the power adapter board; the mounting bracket has a recess, the power adapter board is placed in the recess, and a connector is provided on the power adapter board; the contact portion of the flexible circuit board extends into the recess and is connected to the connector; a sealing layer is provided in the recess, and the sealing layer completely covers the power adapter board and the connector.

[0006] Preferably, the sealing layer is a sealant layer.

[0007] Preferably, the flexible circuit board has an adhesive layer on its back side, and the flexible circuit board is bonded to the mounting surface of the mounting bracket through the adhesive layer.

[0008] Preferably, the flexible circuit board is provided with positioning holes, and the mounting surface is provided with positioning posts that are inserted and engaged with the positioning holes.

[0009] Preferably, the mounting bracket has a protruding cable tray near the cavity.

[0010] Preferably, the wire harness plate has a T-shaped structure.

[0011] Preferably, it also includes a locking screw that secures the adapter power board within the cavity.

[0012] Preferably, the switching element is a waterproof switch structure.

[0013] Preferably, the flexible circuit board has a sealing and protective layer on its surface.

[0014] Secondly, this utility model provides a handlebar switch, including the switch assembly described above.

[0015] The positive effects of this utility model are as follows: This utility model optimizes the structure by setting a cavity and placing the power adapter board and its connector to the flexible circuit board inside, and then using a sealing layer to fully cover it, creating a closed protective environment. This compensates for the weak electrical connection in traditional handle switches that are easily damaged by moisture, fundamentally blocking the intrusion of moisture, dust and corrosive gases, and significantly improving the protection level and long-term reliability of the core circuit.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] The structure of the high-protection-level switch assembly in this embodiment of the invention is as follows: Figures 1 to 3 As shown, the device includes a mounting bracket 1, a flexible circuit board 2, a switching element 3, and a power adapter board 4. The switching element 3 is mounted on the flexible circuit board 2, and the flexible circuit board 2 is electrically connected to the power adapter board 4. The mounting bracket 1 has a recess 11, and the power adapter board 4 is placed inside the recess 11. A connector 41 is provided on the power adapter board 4. The connector 41 can adopt the existing FPC connector 41 structure, which will not be described in detail here. The contact part of the flexible circuit board 2 extends into the recess 11 and connects to the connector 41. A sealing layer (not shown in the figure) is provided inside the recess 11, and the sealing layer completely covers the power adapter board 4 and the connector 41. In this embodiment, by setting a recess 11 and placing the power adapter board 4 and its connector 41 to the flexible circuit board 2 inside it, and then using a sealing layer for complete coverage, a closed protective environment is created. This compensates for the weak electrical connection in traditional handle switches that is easily damaged by moisture, fundamentally blocking the intrusion of moisture, dust, and corrosive gases, and significantly improving the protection level and long-term reliability of the core circuit.

[0024] Furthermore, the sealing layer is preferably a sealant layer, that is, the sealant (such as epoxy resin) is cured to form a sealing layer. During the production stage, liquid sealant is poured into the cavity 11 and penetrates and fills the gaps in the cavity. After the sealant is cured, the sealing layer formed can achieve a wrap-around seal in dead corners to ensure protective performance.

[0025] In some embodiments, an adhesive layer is provided on the back of the flexible circuit board 2, and the flexible circuit board 2 is bonded to the mounting surface 12 of the mounting bracket 1 through the adhesive layer. This method of fixing the flexible circuit board 2 is simple, feasible, and secure. Furthermore, to ensure accurate positioning of the flexible circuit board 2, positioning holes 21 are provided on the flexible circuit board 2, and positioning posts 13 are provided on the mounting surface 12. The positioning posts 13 are inserted into the positioning holes 21 to ensure accurate mounting position of the flexible circuit board 2.

[0026] See Figure 2As shown, the mounting bracket 1 has a protruding cable management plate 14 near the cavity 11. The cable harness connected to the adapter power board 4 can be bound to the cable management plate 14 with cable ties, thereby preventing the cable harness from detaching from the adapter power board 4 when pulled by external force. Preferably, the cable management plate 14 is a T-shaped structure, which can block and limit the cable ties, preventing them from slipping off.

[0027] To ensure the stability of the adapter power board 4, this embodiment also includes a locking screw 5, which fixes the adapter power board 4 in the cavity 11.

[0028] Preferably, the switching element 3 is configured as a waterproof switch structure, such as a waterproof micro switch, a waterproof tactile switch, or a sealing sleeve is directly installed on the outside of the switching element 3 for protection, so as to enhance the protection performance of the switching element 3.

[0029] The flexible circuit board 2 has a sealing and protective layer on its surface. The sealing and protective layer can improve the protection performance of the flexible circuit board 2. The sealing and protective layer can be a waterproof coating.

[0030] Secondly, this utility model embodiment also provides a handlebar switch, which includes a switch housing, and the high protection level switch component of the above embodiment is disposed inside the switch housing. Specifically, the mounting bracket 1 is fixed inside the switch housing. Since the high protection level switch component in this embodiment adopts the structure of the above embodiment, it also has all its advantages, which will not be elaborated here.

[0031] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
