The moving contact is located on the driven wheel and rotates synchronously with the driven wheel. The moving contact has two sets of contact feet, each set having two contact feet arranged symmetrically. The fixed base has a conductive plate on the side facing the driven wheel. The conductive plate has several sets of insulating areas, each set having two insulating areas arranged symmetrically. One set of contact feet contacts the conductive plate, and the other set of contact feet contacts the insulating area.

[0006] The conductive sheet is provided in two symmetrically arranged on the fixed base, and the two ends of the two conductive sheets are separated to form the insulating area. Each conductive sheet is provided with at least one set of the insulating area.

[0007] By adopting the above technical solution, the rotation of the toggle wheel drives the driven wheel to rotate, so that the contact foot contacts the conductive or insulating area at different positions to achieve signal switching, thereby enabling the application of different functions and solving the problem of the single function of existing switches.

[0008] A further feature of this invention includes a stop component and a positioning post. The positioning post is located on the side of the driven wheel away from the fixed seat and is partially located on the inner circumference of the actuating wheel.

The inner sidewall of the driven wheel is provided with several stop grooves along its circumference. The stop component is located in the stop groove to achieve positioning and engagement.

[0009] Further configuration: The stop component is made of steel balls, and the positioning post has a groove. The stop component is partially located in the groove and abuts against the spring located in the groove.

[0010] The above-mentioned further settings improve the operating feel, make gear shifting clear, and ensure durability and reliability, while also facilitating gear shifting.

[0011] A further feature of this invention is that a positioning ring is provided on the positioning post along its circumference. The positioning ring is located inside the actuating wheel and outside the driven wheel to position the driven wheel.

[0012] By adopting the above-mentioned further settings, the driven wheel is positioned to prevent it from disengaging from the actuating wheel, and the stop groove is not exposed, making it more aesthetically pleasing.

[0013] A further improvement of this invention is that the driven wheel is provided with a square connecting post, the moving contact plate is provided with a square hole, and the connecting post is inserted into the square hole to achieve synchronous rotation of the moving contact plate and the driven wheel.

[0014] The above-mentioned further configuration makes the connection convenient and does not affect the synchronous rotation of the moving contact and the driven wheel.

[0015] A further feature of this invention is that it includes a cover plate located inside the actuating wheel and outside the fixed base. The cover plate has an annular groove along its circumference, and a sealing ring that seals with the actuating wheel is provided in the annular groove.

[0016] With the above-mentioned further design, the cover plate and positioning post respectively seal both sides of the actuation wheel to prevent the structure located inside the actuation wheel from detaching from the actuation wheel, and the sealing ring improves the waterproofness of the roller switch.

[0028] like Figure 1-6As shown, an electric vehicle roller switch signal switching structure includes a toggle wheel 1, a driven wheel 2, a moving contact 3, and a fixed base 4. The driven wheel 2 and the fixed base 4 are located on the inner circumference of the toggle wheel 1. The driven wheel 2 rotates synchronously with the toggle wheel 1 and can be interference-fitted with the toggle wheel 1. The moving contact 3 is located on the driven wheel 2 and rotates synchronously with it. The driven wheel 2 has a square connecting post 21, and the moving contact 3 has a square hole 31. The connecting post 21 is inserted into the square hole 31 to achieve synchronous rotation of the moving contact 3 and the driven wheel 2. The connection is convenient and does not affect the synchronous rotation of the moving contact 3 and the driven wheel 2. The moving contact 3 is provided with two sets of contact feet 32, each set of contact feet 32 ​​has two and is symmetrically arranged. The fixed base 4 has a conductive plate 41 on the side facing the driven wheel 2. The conductive plate 41 is connected to the circuit board inside the electric vehicle handlebar through a connecting wire. The conductive plate 41 is provided with several sets of insulating areas 411, and the rest are conductive areas. Each set of insulating areas 411 has two and is symmetrically arranged. One set of contact feet 32 ​​contacts the conductive plate 41, and the other set of contact feet 32 ​​contacts the insulating area 411. Figure 3 As shown in ①②③, the contact pins contact different conductive and insulating areas. The changes in the contact pins can be used to switch signals in the circuit to achieve different functions. One set of contact pins is responsible for contacting the conductive area to ensure the flow of current or signal, while the other set of contact pins isolates the signal by contacting the insulating area to avoid interference or incorrect current paths.

[0029] Specifically, there are two conductive sheets 41, which are symmetrically arranged on the fixed base 4. The two ends of the two conductive sheets 41 are separated to form the insulating area 411. Each conductive sheet 41 is provided with at least one set of the insulating area 411. By rotating the toggle wheel 1, the driven wheel 2 is driven to rotate, so that the contact foot 32 contacts the conductive area or insulating area 411 at different positions to realize the switching of signals. In this way, different functions can be applied to solve the problem of the single function of the existing switch.

[0030] It also includes a stop component 5 and a positioning post 6. The positioning post 6 is located on the side of the driven wheel 2 away from the fixed base 4, and partly located on the inner circumference of the actuating wheel 1. The stop component 5 is located on the part of the positioning post 6 located on the inner circumference of the actuating wheel 1. The inner sidewall of the driven wheel 2 is provided with several stop grooves 22 along its circumference. The stop component 5 is located in the stop grooves 22 to achieve positioning and engagement. The stop component 5 is made of steel balls. The positioning post 6 is provided with a groove 61, or it can be a columnar body with an arc-shaped end. The stop component 5 is partially located in the groove 61 and abuts against the spring located in the groove 61, which improves the operating feel, makes gear switching clear, and is durable and reliable, while also facilitating gear switching. The positioning post 6 is provided with a positioning ring 62 along its circumference. The positioning ring 62 is located inside the actuating wheel 1 and outside the driven wheel 2 to position the driven wheel 2, prevent it from disengaging from the actuating wheel 1, and make the stop grooves 22 not exposed, which is more aesthetically pleasing.

[0031] It also includes a cover plate 7, which is located inside the actuating wheel 1 and outside the fixed base 4. The cover plate 7 has an annular groove along its circumference, and a sealing ring 71 that seals with the actuating wheel 1 is provided in the annular groove. The cover plate 7 and the positioning post 6 respectively seal the two sides of the actuating wheel 1 to prevent the structure located inside the actuating wheel 1 from detaching from the actuating wheel 1. The sealing ring 71 improves the waterproofness of the roller switch.
