[0022] Examples, such as Figures 1 to 9 As shown, an integrated rotary switch includes a housing 1, a cover 20 covering the housing, a base 2 mounted on the housing 1, a main circuit board 3 mounted on the base 2, and conductive rubber 4 mounted above the main circuit board 3. A support mounting cylinder 101 is provided on the housing 1, and a toggle switch fixing seat 6 is fitted over the support mounting cylinder 101. A toggle switch 7 is fixedly mounted on the toggle switch fixing seat 6, and the toggle switch fixing seat 6 can move up and down relative to the support mounting cylinder 101. To facilitate operation of the toggle switch 7, a protrusion 71 is provided on the toggle switch 7, which can be rotated by pressing one side of the protrusion 71 with a finger, making operation simple and convenient. To achieve circuit functionality and a good tactile feedback, the bottom of the toggle switch mounting base 6 is provided with a pressing track 61 and a shift track 62. The pressing track 61 includes a first pressing track and a second pressing track arranged opposite to each other. Below the first pressing track and the second pressing track, there is a first pressure rod 8. The first pressure rod 8 is assembled inside the housing 1. The conductive rubber 4 is provided with a first conductive rubber post 41 that cooperates with the first pressure rod 8, and the bottom of the first pressure rod 8 rests on the first conductive rubber post 41. When the toggle switch 7 is turned to the left, the first pressing track 611 is activated, pressing down the first pressure rod 8 and making the first conductive rubber post 41 below the first pressing track 611 conductive. At this time, the second pressing track 612 does not exert a downward force on the first pressure rod 8 below. When the toggle switch 7 is turned to the right, the second pressing track 612 is activated, pressing down the first pressure rod 8 and making the first conductive rubber post 41 below the second pressing track 612 conductive. At this time, the first pressing track 611 does not exert a downward force on the first pressure rod 8 below. Two gear shift tracks 62 are symmetrically arranged, and each gear shift track 62 has a V-shaped structure. A gear shift pin 9 that cooperates with the gear shift track 62 is provided inside the outer casing 1. A push-out spring 10 is provided below the gear shift pin 9. The gear shift pin 9 slides within the gear shift track 62. When the shift knob 7 is released, the shift knob 7 quickly returns to its original position under the action of the gear shift track 62, and the gear shift pin 9 rests on the top of the V-shaped structure of the gear shift track 62. To control the upper travel of the shift knob fixing seat 6, a shift knob pressure block 5 is also fixedly installed on the outer casing 1. The shift knob pressure block 5 presses against the shift knob fixing seat 6 to limit the upper travel of the shift knob fixing seat 6.

[0023] The support mounting cylinder 101 contains a knob inner shell 12 that can move up and down. To ensure vertical movement, a set of vertical guide ribs 102 are provided on the inner wall of the support mounting cylinder 101, and a set of vertical guide grooves 121 that are adapted to the vertical guide ribs 102 are provided on the outer wall of the knob inner shell 12. A light guide 19 is snap-fitted and fixed inside the knob inner shell 12, and a stop block 13 is snap-fitted and fixed inside the light guide 19. A knob 14 is rotatably mounted on the stop block 13. Pressing down the knob 14 causes the stop block 13, the fixedly connected light guide 19, and the knob inner shell 12 to move downward together. A knob pressing block 11 is fixedly installed below the inner shell 12 of the knob. Three second pressing rods 111 are provided on the knob pressing block 11. Three second conductive rubber pillars 42 adapted to the second pressing rods 111 are provided on the conductive rubber 4. When the inner shell 12 of the knob moves downward, it drives the knob pressing block 11 to move downward, thereby causing the second pressing rods 111 to press down on the second conductive rubber pillars 42, so that the second conductive rubber pillars 42 deform and the circuit is connected.

[0024] A rotating block 15 is connected below the knob 14. A gear position grid 151 is provided on the rotating block 15. A sub-circuit board 16 is provided on the knob pressing block 11. A photoelectric sensor 161 that cooperates with the gear position grid 151 is provided on the sub-circuit board 16. Rotating the knob 14 causes the rotating block 15 to rotate together, so that the gear position grid 151 alternates on the photoelectric sensor 161, realizing signal switching, thereby realizing gear adjustment.

[0025] To improve the feel of rotating the knob 14, the inner ring of the gear block 13 is provided with a ring of gear teeth 131, and the knob 14 is provided with a gear spring 17 that cooperates with the gear teeth 131. The gear spring 17 includes a U-shaped gear part 171 that engages with the gear teeth 131 and elastic support parts 172 extending to both sides from the U-shaped gear part 171. When the knob 14 is rotated, the gear spring 17 mounted on the knob 14 is deformed under the action of the gear teeth 131 and bounces on the gear teeth 131, thereby achieving the gear shift feel.

[0026] To reduce rotational friction and improve the service life of the parts, a rotating bearing 18 is provided between the knob 14 and the light guide 19, and the rotating bearing 18 is supported above and below the gear block 13 to provide support for the gear block 13.

[0027] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
