Detailed Implementation

[0034] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0035] Please refer to Figures 1-15This embodiment provides a driving mode switching switch, including a housing 1 and a circuit board 2 installed inside the housing 1. The outer periphery of the housing 1 has an annular guide groove 111 with its opening facing upwards and a knob sleeve 3 rotatably mounted above the annular guide groove 111. The bottom of the knob sleeve 3 has an annular drive ring 311 extending into the annular guide groove 111, and the inner sidewall of the annular drive ring 311 has a gear ring 312. The lower surface of the circuit board 2 has a switching component 4 for switching different gears. Inside the housing 1, there is a gear set 5 located below the circuit board 2. The input end of the gear set 5 meshes with the gear ring 312 for transmission. The inner sidewall of the annular guide groove 111 has an clearance opening 112, and the output end of the gear set 5 is linked to the switching component 4. Thus, by rotating the knob sleeve 3, the meshing transmission between the gear ring 312 on the knob sleeve 3 and the gear set 5 can link the switching component 4 to complete the gear switching, thereby realizing gear adjustment for different driving modes. The structure is simple, relatively stable and reliable, and also has a good operating feel.

[0036] In some implementations, reference Figure 3 , Figure 5 , Figures 7-10 The gear set 5 includes a first gear 51 and a second gear 52 that mesh and drive each other. The rotation shafts of the first gear 51 and the second gear 52 are parallel to the rotation shaft of the knob sleeve 3. The first gear 51 is meshed and driven by the gear ring 312, and the second gear 52 is linked to the switching assembly 4. Preferably, in order to reduce the overall size and make full use of the space inside the housing 1, a coaxially distributed transition gear is fixedly connected to the first gear 51. The transition gear is meshed with the second gear 52. Thus, when the first gear 51 rotates due to the rotational force transmitted by the knob sleeve 3, it can drive the second gear 52 to rotate through the transition gear, thereby realizing gear switching.

[0037] In some specific implementation methods, refer to Figure 5 Figure 7 and Figure 8 The switching component 4 includes several annularly spaced light-blocking plates 41 connected to the second gear 52, and photoelectric sensors 42 corresponding to the positions of the light-blocking plates 41. Thus, when the knob sleeve 3 is rotated, the gear ring 312 on the knob sleeve 3 drives the first gear 51 to rotate. The first gear 51, through a transition gear, drives the second gear 52 to rotate, causing the light-blocking plates 41 located on the second gear 52 to pass through the photoelectric sensors 42 on the circuit board 2, thereby achieving the gear switching function. For example, rotating the knob sleeve 3 clockwise and passing a light-blocking plate 41 through the photoelectric sensor 42 represents increasing the gear by one level; rotating the knob sleeve 3 counterclockwise and passing a light-blocking plate 41 through the photoelectric sensor 42 represents decreasing the gear by one level.

[0038] Specifically, as an example, the photoelectric sensor 42 can be a slotted photoelectric sensor 42, which is an optical coupler with its slot facing downwards, allowing the light-blocking plate 41 to pass through when rotating, thereby forming a LIN signal output to realize the gear switching function.

[0039] In other implementations, refer to Figures 13-15 The switching component 4 can also use other methods to achieve the gear switching function. For example, the switching component 4 includes a conductive spring 43 connected to the second gear 52, a first conductive connecting disk 44 arranged in a ring shape, and a plurality of second conductive connecting disks 45 arranged coaxially and spaced around the first conductive connecting disk 44; the conductive spring 43 includes a first conductive contact 431 that slides against the first conductive connecting disk 44, a second conductive contact 432 that slides against the second conductive connecting disk 45, and a third conductive contact 433 connected between the first conductive contact 431 and the second conductive contact 432. Thus, the conductive spring 43 elastically abuts against the circuit board 2 and can rotate and slide on the surface of the circuit board 2. When the knob sleeve 3 is rotated, the gear ring 312 on the knob sleeve 3 drives the first gear 51 to rotate. The first gear 51 drives the second gear 52 to rotate through the transition gear, thereby causing the conductive spring 43 located on the second gear 52 to rotate synchronously. The first conductive contact 431 always maintains sliding contact with the first conductive connecting plate 44 during rotation, while the second conductive contact 432 slides against the second conductive connecting plate 45 in sequence during rotation, realizing the gear switching function as a hard-wired output. As an example, the first conductive connecting plate 44 can be used as a common terminal, and each second conductive connecting plate 45 can be connected to the terminal representing different gears in sequence; rotating the knob sleeve 3 clockwise and causing the second conductive contact 432 to slide against the next second conductive connecting plate 45 represents adding a gear, and rotating the knob sleeve 3 counterclockwise and causing the second conductive contact 432 to slide against the previous second conductive connecting plate 45 represents deleting a gear.

[0040] More specifically, the first conductive contact plate 44 and the second conductive contact plate 45 are gold finger structures formed and fixed on the circuit board 2. The conductive spring 43 is formed by stamping and cutting metal springs.

[0041] In some specific implementation methods, refer to Figure 14 and Figure 15 The third conductive contact 433 is bent to provide an insert 434, and the second gear 52 is provided with a slot 521 for engaging with the insert 434. In this way, the conductive spring 43 is fixed to the second gear 52 by insertion.

[0042] In some improved implementations, refer to Figure 4 , Figure 5 , Figure 9 and Figure 10The lower surface of the annular drive ring 311 is provided with alternating concave and convex pressing surfaces 313 around the central axis of the annular drive ring 311. The annular guide groove 111 is provided with a stop pin assembly 6 that elastically engages with the concave and convex pressing surfaces 313. Specifically, the stop pin assembly 6 includes a stop pin 61 and a spring 62, with both ends of the spring 62 connected to the stop pin 61 and the housing 1, respectively. Thus, when the knob sleeve 3 is rotated, the concave and convex pressing surfaces 313 on the annular drive ring 311 cause the stop pin 61 to compress the spring 62, resulting in a telescoping motion that provides good force feedback and thus a good operating feel.

[0043] In some specific implementation methods, refer to Figure 4 , Figure 6 and Figure 10 The knob sleeve 3 includes a rotating frame 31 and a knob drive ring 32 that engages with the upper part of the rotating frame 31. The outer sidewall of the rotating frame 31 is provided with annularly distributed, outwardly protruding positioning plates 314. The inner sidewall of the housing 1 near the annular guide groove 111 is provided with several limiting buckles 113 located above the rotating frame 31. During installation, the knob sleeve 3 is inserted into the annular guide groove 111 along the upper part of the housing 1 until the limiting buckles 113 engage with the upper part of the rotating frame 31. At this time, the annular positioning plates 314 abut against the outer edge of the annular guide groove 111, thereby supporting the knob sleeve 3 to rotate smoothly and steadily along the annular guide groove 111.

[0044] Furthermore, in some implementations, references Figures 1-4 , Figure 6 , Figure 7 , Figure 11 and Figure 12 The housing 1 has a vertically arranged first slide groove 114 and several second slide grooves 115 circumferentially distributed around the first slide groove 114. A first button assembly 7 is slidably connected to the first slide groove 114, and second button assemblies 8 are slidably connected to the second slide grooves 115. The upper surface of the circuit board 2 has a first micro switch 21 corresponding to the bottom of the first button assembly 7 and a second micro switch 22 corresponding to the bottom of the second button assemblies 8. As an example, the first button assembly 7 in the middle corresponds to the crawl mode, and the four second button assemblies 8 around it correspond to the high-speed two-wheel drive mode (2H), low-speed four-wheel drive mode (4L), high-speed four-wheel drive mode (4H), and intelligent four-wheel drive mode (4A), respectively. By pressing the corresponding function button, the corresponding driving mode can be switched.

[0045] In some specific implementation methods, refer to Figure 1 , Figures 3-5 , Figure 7 , Figure 11 and Figure 12The top surface of the first button assembly 7 has a first translucent character 711, and the top surface of the second button assembly 8 has a second translucent character 811. The upper surface of the circuit board 2 has a first LED indicator 23 located below the first button assembly 7 and a second LED indicator 24 located below the second button assembly 8. The first button assembly 7 includes a first button cover 71 and a first slider 72 that are fastened together. The first slider 72 has a vertically distributed first light guide channel 721, and the first light guide channel 721 has a first light guide body 73. The two ends of the first light guide body 73 face the first translucent character 711 and the first LED indicator 23, respectively. The second button assembly 8 includes a second button cover 81 and a second slider 82 that are fastened together. The second slider 82 has a vertically distributed second light guide channel 821, and the second light guide channel 821 has a second light guide body 83. The two ends of the second light guide body 83 face the corresponding second translucent character 811 and the second LED indicator 24, respectively. When the corresponding function button is pressed, the corresponding LED light can be illuminated as an indication and reminder.

[0046] As an improved implementation method, refer to Figure 3 and Figure 5 The circuit board 2 is covered with a waterproof silicone cover 9, which can improve the waterproof performance.

[0047] In some specific implementation methods, refer to Figure 3 and Figure 5 The housing 1 includes a detachably connected housing 11 and a base 12. The base 12 is connected to the housing 11 by a number of screws 13. A receiving space for placing the circuit board 2 is formed between the housing 11 and the base 12.
