Description

Technical Field

[0002] Motorcycle roller switch is a widely used multi-functional control device on motorcycles, typically integrating multiple operation methods such as scrolling up and down, pressing left and right, and pressing the center, to achieve convenient control of various motorcycle functions. These switches are usually mounted on the handlebars for easy operation by the rider while riding, aiming to provide efficient functional control while minimizing rider distraction, thereby improving driving safety and convenience. However, existing roller switch designs have some technical limitations. Specifically, the switch module typically uses a microswitch mounted on a circuit board and covered with a waterproof sleeve. The use of microswitches in existing roller switch modules results in higher application costs and a larger overall size of the switch module. Utility Model Content

[0025] 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.

[0026] 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.

[0027] The roller switch structure in this embodiment is shown below. Figures 1 to 7As shown, it includes a switch base 1, a roller bracket 2 movably mounted on the switch base 1, a switch module 3 mounted on the switch base 1, and a roller 4 mounted on the roller bracket 2. In use, the switch module 3 can be controlled by controlling the roller 4 to roll up and down, swing left and right, or press down. The roller bracket 2 is controlled to move to trigger the switch module 3. The switch module 3 includes a circuit board 31 and a rubber pad 32 covering the upper part of the circuit board 31. The surface of the circuit board 31 is provided with several switch groups. Each switch group includes a first conductive disk 311 and a second conductive disk 312 spaced apart. A contact portion 321 is formed on the rubber pad 32 at a position corresponding to each switch group. A conductive spring 33 is mounted at the lower part of the contact portion 321. Normally, the conductive spring 33 does not simultaneously contact the first conductive disk 311 and the second conductive disk 312 (i.e., the conductive spring 33 does not contact either the first conductive disk 311 or the second conductive disk 312, or the conductive spring 33 does not contact the first conductive disk 311 or the second conductive disk 312). When one of the first conductive disk 311 and the second conductive disk 312 is in contact with the other, the switch is in an open circuit state. When the contact part 321 is pressed downward by an external force, the conductive spring 33 conducts the first conductive disk 311 and the second conductive disk 312 (that is, at this time, the conductive spring 33 is in contact with both the first conductive disk 311 and the second conductive disk 312, and the switch is in a conducting state). In this embodiment, the roller switch structure uses a switch unit composed of a switch group and a conductive spring 33 to replace the micro switch, replacing the complex structure of the traditional micro switch (reducing the number and complexity of mechanical parts), which not only simplifies the structure and reduces the size, but also improves the ease of manufacturing and effectively reduces production costs. In addition, the rubber pad 32 not only limits the conductive spring 33, but also protects the circuit board 31, preventing dust, moisture and other external factors from corroding the circuit board, thereby enhancing the switch's water resistance and environmental adaptability. The rubber pad 32 is preferably made of rubber.

[0028] like Figure 3 As shown, in order to facilitate the installation of the conductive spring 33 on the pressing part 321, a downward-opening cavity 322 is provided in the lower part of the pressing part 321. The conductive spring 33 is inserted into the cavity 322 and the cavity 322 can limit the conductive spring 33, thereby simplifying the installation process of the conductive spring 33 and ensuring that the position of the conductive spring 33 is not easily shifted.

[0029] like Figure 2 and Figure 3As shown, the conductive spring 33 is a dome-shaped piece with its center arched upwards (similar to the shape of a "pot bottom"); the first conductive disk 311 is an annular structure that matches the periphery of the conductive spring 33. This annular structure is preferably a closed ring structure, or the annular structure can also be set as an open ring structure; the second conductive disk 312 is located at the center of the first conductive disk 311. Under normal conditions, the conductive spring 33 is in contact with the first conductive disk 311, and the center of the conductive spring 33 is not in contact with the second conductive disk 312. After the conductive spring 33 is pressed downwards, its center part contacts the second conductive disk 312, thereby conducting electricity between the first conductive disk 311 and the second conductive disk 312 through the conductive spring 33.

[0030] Continue reading Figure 2 and Figure 3 The switch base 1 includes an upper shell 11 and a bottom frame 12. The upper shell 11 has a cutout portion 13. The contact portion 321 is correspondingly arranged to the cutout portion 13 to expose the contact portion 321, thereby ensuring that each contact portion 321 can be triggered when the roller bracket 2 swings. The rubber pad 32 surrounds the periphery of the circuit board 31 and is pressed between the switch base 1 and the bottom frame 12. This design fully covers the circuit board 31 with the rubber pad 32, thereby ensuring protection. Moreover, the rubber pad 32 surrounds the circuit board 31 and is pressed between the upper shell 11 and the bottom frame. The pressing method of 12 can firmly fix the rubber pad 32 and significantly enhance the sealing between the rubber pad 32 and the circuit board 31. The bottom frame 12 is a square frame structure with a hollow area. The wires connected to the circuit board can pass through the hollow area, and the sealant to form the following sealing layer can also be injected through the hollow area. In order to further improve the sealing and protection performance of the circuit board 31, the bottom of the circuit board 31 is also covered with a layer of sealant. The circuit board 31 is effectively sealed by the double combination of the rubber pad 32 and the sealant layer, achieving more comprehensive protection.

[0031] Combined with the diagram, Figure 6 and Figure 7 The circuit board 31 is equipped with a Hall element 34, and the roller 4 contains a plurality of magnets 40 distributed circumferentially. When the roller 4 is rotated, the magnets 40 inside it will rotate synchronously. The Hall element 34 can detect the change in the magnetic field of the magnets 40 in real time and convert it into an electrical signal output, thereby realizing the corresponding control function. For example, in practical applications, the menu switching and other operations can be controlled by rotating the roller 4.

[0032] Combination Figures 5 to 7As shown, the roller 4 includes a roller body 41 and a mounting shaft 42 that passes through the roller body 41. The two ends of the mounting shaft 42 are connected to the roller bracket 2. A groove 43 is provided on one end face of the roller body 41, and multiple positioning grooves 44 are distributed circumferentially in the groove 43. The magnets 40 are embedded in the positioning grooves 44 one by one. An end cover plate 45 is integrally provided on the mounting shaft 42 and embedded in the groove 43. During assembly, the magnets 40 are installed into the positioning grooves 44, and then the mounting shaft 42 is assembled with the roller body 41. The end cover plate 45 is embedded in the groove 43 to close the positioning grooves 44, thereby effectively restricting the magnets 40 and preventing the magnets 40 from becoming loose.

[0033] See Figure 4 The roller body 41 is provided with a fixing hole 46 that extends through the axis. The end cover plate 45 is provided with a fixing post 47 that passes through the fixing hole 46. After the fixing post 47 passes through the fixing hole 46, a hot riveting part is formed at its end. The hot riveting part is formed by heating and pressurizing the end of the fixing post 47, thereby ensuring a reliable fixed connection between the roller body 41 and the mounting shaft 42, significantly enhancing the integrity and stability of the structure, and preventing loosening between the roller body 41 and the mounting shaft 42.

[0034] Combination Figure 4 and Figure 6 The fixing hole 46 has a recessed groove 48 on one end facing away from the end cover plate 45. The diameter of the recessed groove 48 is larger than the diameter of the fixing hole 46. After the hot riveting part is formed, it is located in the recessed groove 48. The hot riveting part is hidden in the recessed groove 48 to avoid exposed riveting marks.

[0035] 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 scope of protection of this invention.
