Description

Technical Field

[0001] The present invention relates to the field of operation control of all - terrain vehicles, and specifically provides an all - terrain vehicle. Background Art

[0002] As a vehicle capable of traveling on various complex terrains, the switching of the driving mode of an all - terrain vehicle is crucial for adapting to different driving conditions. The related all - terrain vehicle driving mode switching technologies mainly have the following methods: One is to achieve mode switching through a single button or a double - button. This method is relatively simple to operate when the number of modes is small, but when the number of modes increases, the convenience and accuracy of operation will significantly decrease. Another is to use a Hall sensor as the switching knob for mode switching. Although this method can achieve multi - mode switching, its cost is relatively high, and in harsh outdoor environments, the waterproof and shock - proof performance of the Hall sensor often fails to meet the usage requirements of all - terrain vehicles.

[0003] In addition, the related knob devices also have certain limitations in structural design. For example, some knob devices can only achieve single - turn rotation, resulting in limited flexibility and accuracy of driving mode switching; there are also some knob devices with relatively complex circuit designs, which not only increase the manufacturing cost but also reduce the reliability of the system. Summary of the Invention

[0004] To solve the deficiencies of the prior art, the purpose of this application is to provide an all - terrain vehicle that can achieve precise switching of multi - mode driving at low cost.

[0005] To achieve the above - mentioned purpose, the following technical solutions are adopted in this application:

[0006] An all-terrain vehicle, which includes a running system, a power system, and an electrical system. The power system can output power, and the power can be transmitted to the running system. The electrical system is at least used to control the power system, and the electrical system includes: a control module and a knob switch module. The knob switch module is configured to send a control signal to the control module in response to a rotational operation of a user, and the control module can switch the driving mode of the all-terrain vehicle according to the control signal; the knob switch module includes a knob, a fixing member, and a mode switching circuit. The knob can rotate multiple circles relative to the fixing member around its own rotation center line, and the mode switching circuit is located between the knob and the fixing member; wherein, the mode switching circuit includes a conductive terminal located on the knob, a circuit board located on the fixing member, and a conductive sheet located on the side of the circuit board facing the conductive terminal. When the knob is rotated, the conductive terminal rotates relative to the conductive sheet; the conductive sheet covers a partial area of the circuit board, and the area of the circuit board not covered by the conductive sheet and the area covered by the conductive sheet together form a mode selection area. The mode selection area includes multiple mode selection sub-areas. When the knob rotates relative to the fixing member, the conductive terminal contacts at least one mode selection sub-area to generate a control signal, and the control module can determine the corresponding driving mode based on the control signal and switch the all-terrain vehicle to the corresponding driving mode.

[0007] In one embodiment, the conductive sheet includes a first metal sheet and a second metal sheet, and the conductive terminal includes a first contact and a second contact; when the knob rotates, one of the first contact and the second contact always contacts the first metal sheet, and the other contact contacts the second metal sheet or the area of the circuit board not covered by the conductive sheet; wherein, the area of the circuit board not covered by the conductive sheet and the area covered by the second metal sheet together form multiple mode sub-selection areas.

[0008] In one embodiment, the first metal sheet is arranged in a ring shape, the center of the first metal sheet is located on the rotation center line, the conductive sheet includes multiple second metal sheets, and there is a gap between adjacent two second metal sheets.

[0009] In one embodiment, the multiple second metal sheets are located at the outer edge of the first metal sheet, and the mode selection area is located at the outer edge of the first metal sheet; wherein, the second metal sheet is arranged in a sector ring shape.

[0010] In one embodiment, a first connection point and a second connection point are provided on the circuit board, the mode switching circuit includes a first conductive terminal and a second conductive terminal, and the first conductive terminal and the second conductive terminal are distributed on opposite sides of the rotation center line; when the knob rotates, the first conductive terminal and the second conductive terminal can be conducted with the first connection point or the second connection point.

[0011] In one embodiment, the conductive sheet includes four second metal sheets. The first connection point is connected to two adjacent second metal sheets, and the second connection point is connected to the remaining two adjacent second metal sheets. When the knob rotates, one of the first contact and the second contact is always in contact with the first metal sheet. If the other contact is in contact with the second metal sheet, the first connection point or the second connection point connected to the second metal sheet is turned on.

[0012] In one embodiment, the control module includes an α pin and a β pin. The α pin is connected to the first connection point, and the β pin is connected to the second connection point. If the first connection point is turned on, the value corresponding to the α pin is 1; otherwise, the value corresponding to the α pin is 0. If the second connection point is turned on, the value corresponding to the β pin is 1; otherwise, the value corresponding to the β pin is 0.

[0013] In one embodiment, a plurality of mode selection sub-regions are uniformly arranged around the rotation center line. Each mode selection sub-region has a central angle coinciding with the rotation center line. When the knob rotates a set angle each time, the conductive terminal can trigger different mode selection sub-regions to perform the selection of the driving mode.

[0014] In one embodiment, the region of the circuit board not covered by the conductive sheet and the region covered by the conductive sheet together form 12 mode selection sub-regions. The knob rotates 30 degrees each time it rotates once, and the 12 mode selection sub-regions are used for the switching between the first mode, the second mode, and the third mode. The first mode is the normal mode, the second mode is the sports mode, and the third mode is the track mode.

[0015] In one embodiment, when the knob rotates clockwise, it cyclically switches in the order of the first mode - the second mode - the third mode - the first mode. When the knob rotates counterclockwise, it cyclically switches in the order of the first mode - the third mode - the second mode - the first mode.

[0016] In one embodiment, after the knob rotates the first angle, the control module can determine the driving mode for the next switch of the all-terrain vehicle according to the recorded current driving mode and the values corresponding to the rotated α pin and β pin. Wherein, the first angle is an integer multiple of 30 degrees.

[0017] In one embodiment, when the knob rotates clockwise, the driving mode of the all-terrain vehicle can be switched from the first mode to the second mode and from the second mode to the third mode. When the driving mode of the all-terrain vehicle is switched to the third mode, it does not cycle. When the knob rotates counterclockwise, the driving mode of the all-terrain vehicle can be switched from the third mode to the second mode and from the second mode to the first mode. When the driving mode of the all-terrain vehicle is switched to the first mode, it does not cycle.

[0018] In one embodiment, after the knob rotates by a second angle, the control module determines the rotation direction of the knob based on the recorded current driving mode, the values corresponding to the α and β pins before the knob rotates by the second angle, and the values corresponding to the α and β pins after the knob rotates by the second angle; the control module can determine the driving mode that the all-terrain vehicle needs to switch to according to the rotation direction of the knob; wherein, the second angle is an integer multiple of 30 degrees.

[0019] In one embodiment, if the current driving mode is the first mode and the rotation direction of the knob is counterclockwise rotation, the control module maintains the driving mode as the first mode and assigns the values corresponding to the α and β pins after rotation as the first mode; if the current driving mode is the first mode and the rotation direction of the knob is clockwise rotation, the control module switches the driving mode to the second mode; if the current driving mode is the third mode and the rotation direction of the knob is counterclockwise rotation, the control module switches the driving mode to the second mode; if the current driving mode is the third mode and the rotation direction of the knob is clockwise rotation, the control module maintains the driving mode as the third mode and assigns the values corresponding to the α and β pins after rotation as the third mode.

[0020] For the all-terrain vehicle described above, the driving mode switching method of the all-terrain vehicle is implemented through a knob switch module and a control module. The knob switch module includes a rotatable knob, a fixing member, and a mode switching circuit located between the two. When the user rotates the knob, the conductive terminal of the knob rotates relative to the conductive sheet of the fixing member, and the conductive sheet covers a part of the circuit board area. The area not covered by the conductive sheet and the area covered by the conductive sheet together form multiple mode selection sub-areas. When the conductive terminal contacts different mode selection sub-areas, corresponding control signals are generated. After receiving these signals, the control module accurately determines the driving mode selected by the user and switches the all-terrain vehicle to the corresponding driving mode. This method can achieve precise multi-mode switching of the all-terrain vehicle at low cost. Description of the Drawings

[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] The present application provides an all - terrain vehicle 100, as Figure 1 shown. The all - terrain vehicle 100 includes: a running system 10, a power system 20, and an electrical system 30. The running system 10 includes drive wheels. The drive wheels are key components for the all - terrain vehicle 100 to travel and are responsible for converting power into the movement of the all - terrain vehicle 100. The power system 20 is responsible for generating power and transmitting the power to the drive wheels to drive the all - terrain vehicle 100 to move forward or backward. The electrical system 30 includes a control module 31 and a knob switch module 32. The knob switch module 32 is configured to send a control signal to the control module 31 in response to a user's rotation operation, and the control module 31 can switch the driving mode of the all - terrain vehicle 100 according to the control signal.

[0032] Among them, the knob switch module 32 is as Figure 2As shown, the rotary switch module 32 includes a knob 321, a fixing member 322, and a mode switching circuit 323. The knob 321 can rotate multiple turns relative to the fixing member 322 around its own rotation center line C, and the mode switching circuit 323 is located between the knob 321 and the fixing member 322. It should be noted that the mode switching circuit 323 includes a conductive terminal located on the knob 321, a circuit board 3233 located on the fixing member 322, and a conductive sheet 3234 located on the side of the circuit board 3233 facing the conductive terminal. The knob 321 can achieve multi-turn rotation, providing a flexible operation method for the user. The fixing member 322 can be the stationary part in the rotary switch module 32, providing support and positioning for the knob 321. The mode switching circuit 323 is located between the knob 321 and the fixing member 322, and can generate corresponding control signals according to the rotation position and action of the knob 321, and transmit the control signals to the control module 31, so as to realize the switching of the driving mode. Among them, the physical structure of the control module 31 can include a microcontroller (MCU) or a microprocessor, as well as the supporting circuit board 3233 and electronic components. For example, the control module 31 can include a high-performance ARM Cortex-M series microcontroller for receiving the control signals of the rotary switch module 32.

[0033] Further, as Figure 3 and Figure 4 shown, the number of conductive terminals is at least one. In the embodiment of the present application, the number of conductive terminals is two, namely a first conductive terminal 3231 and a second conductive terminal 3232, and the first conductive terminal 3231 and the second conductive terminal 3232 have the same structure. When the knob 321 rotates in response to the user's rotation operation, the conductive terminal rotates relative to the conductive sheet 3234, so that the conductive terminal contacts or disengages from the conductive sheet 3234. The side of the circuit board 3233 covered with the conductive sheet 3234 is the front side of the circuit board 3233, and the front side of the circuit board 3233 faces the conductive terminal. As Figure 5 shown, the area of the circuit board 3233 not covered by the conductive sheet 3234 and the area covered by the conductive sheet 3234 together form a mode selection area, and the mode selection area includes multiple mode selection sub-areas. When the knob 321 rotates relative to the fixing member 322, the conductive terminal contacts the mode selection sub-area, generates a control signal, and the control module 31 can determine the corresponding driving mode based on the control signal and switch the all-terrain vehicle 100 to the corresponding driving mode.

[0034] Exemplarily, during the operation of the all-terrain vehicle 100, when the user rotates the knob switch module 32, the knob 321 can drive the conductive terminal to rotate relative to the conductive sheet 3234. The conductive terminal can sequentially contact different mode selection sub-regions. When the conductive terminal contacts a certain mode selection sub-region, a specific control signal can be generated. The control signal can be transmitted to the control module 31, and the control module 31 can determine the corresponding driving mode according to the signal and switch the all-terrain vehicle 100 to this mode.

[0035] In this embodiment, the driving mode switching method of the all-terrain vehicle 100 is implemented by the knob switch module 32 and the control module 31. The knob switch module 32 includes a rotatable knob 321, a fixing member 322, and a mode switching circuit 323 located therebetween. When the user rotates the knob switch module 32, the conductive terminal of the knob 321 rotates relative to the conductive sheet 3234 of the fixing member 322. The conductive sheet 3234 covers a partial area of the circuit board 3233. The area of the circuit board 3233 not covered by the conductive sheet 3234 and the area covered by the conductive sheet 3234 together form a mode selection area, and the mode selection area includes a plurality of mode selection sub-regions. When the conductive terminal contacts different mode selection sub-regions, corresponding control signals are generated. After receiving these signals, the control module 31 accurately determines the driving mode selected by the user and switches the all-terrain vehicle 100 to the corresponding driving mode. This method can achieve precise multi-mode switching of the all-terrain vehicle 100 at low cost, and has a simple structure and high reliability.

[0036] In one embodiment, as Figure 3 shown, the first conductive terminal 3231 includes a first contact 3231a of the first conductive terminal 3231 and a second contact 3231b of the first conductive terminal 3231; similarly, the second conductive terminal 3232 also includes a first contact 3232a of the second conductive terminal 3232 and a second contact 3232b of the second conductive terminal 3232. As Figure 4 shown, the conductive sheet 3234 includes a first metal sheet 3234a and a second metal sheet 3234b. The first metal sheet 3234a and the second metal sheet 3234b cover the front side of the circuit board 3233, that is, the side of the circuit board 3233 facing the conductive terminal. When the knob 321 rotates, one of the first contact 3231a and the second contact 3231b always contacts the first metal sheet 3234a, and the other contact contacts the second metal sheet 3234b or contacts the area of the circuit board 3233 not covered by the conductive sheet 3234.

[0037] It should be noted that the first contact 3231a and the second contact 3231b of the first conductive terminal 3231 are distributed on both sides of the first conductive terminal 3231. The first contact 3231a of the first conductive terminal 3231 is located inside the first conductive terminal 3231. During the rotation of the knob 321, the first contact 3231a of the first conductive terminal 3231 is always in contact with the first metal sheet 3234a. The second contact 3231b of the first conductive terminal 3231 is located outside the first conductive terminal 3231. The second contact 3231b of the first conductive terminal 3231 is in contact with the second metal sheet 3234b or with the area of the circuit board 3233 not covered by the conductive sheet 3234, that is, the second contact 3231b of the first conductive terminal 3231 is in contact with multiple mode selection sub-regions.

[0038] As Figure 6 shown, the first metal sheet 3234a is connected to the negative electrode on the back of the circuit board 3233. The positive electrode on the back of the circuit board 3233 can supply power to the weak electrical device. For example, the positive electrode on the back of the circuit board 3233 can be used to light the background light of the knob switch module 32. Exemplarily, the first contact 3231a of the first conductive terminal 3231 always being in contact with the first metal sheet 3234a can be regarded as one end of the switch in the circuit that is always connected to the circuit. The second contact 3231b of the first conductive terminal 3231 being in contact with the second metal sheet 3234b or with the area of the circuit board 3233 not covered by the second metal sheet 3234b can be regarded as the conducting or non-conducting end of the switch.

[0039] Furthermore, if the first contact 3231a of the first conductive terminal 3231 is always in contact with the first metal sheet 3234a, it can ensure that the control signal circuit in the first conductive terminal 3231 is always conductive, and corresponding control signals are generated based on the contact situation of the second contact 3231b of the first conductive terminal 3231. If the first contact 3231a of the first conductive terminal 3231 cannot always be in contact with the first metal sheet 3234a or there is no first metal sheet 3234a, it can be regarded as the control signal circuit in the first conductive terminal 3231 being disconnected, and no control signals can be generated regardless of how the second contact 3231b of the first conductive terminal 3231 contacts.

[0040] In one embodiment, as Figure 4 shown, the first metal sheet 3234a is arranged in a ring shape, and the center of the first metal sheet 3234a is on the rotation center line C. The conductive sheet 3234 includes multiple second metal sheets 3234b, and there is a gap between adjacent two second metal sheets 3234b. The first metal sheet 3234a being in a ring shape can save the material of the conductive sheet 3234 and simplify the circuit design.

[0041] In one embodiment, asFigure 4 As shown, a plurality of second metal sheets 3234b are located at the outer edge of the first metal sheet 3234a, and the mode selection area is located at the outer edge of the first metal sheet 3234a; wherein, the second metal sheets 3234b are arranged in a sector ring shape. Each of the second metal sheets 3234b is an independent metal sheet, and these second metal sheets 3234b are arranged in a specific pattern on the circuit board 3233, and there is a gap between two adjacent second metal sheets 3234b. Due to the existence of the gap, a plurality of independent mode selection sub-areas are formed on the circuit board 3233, and each mode selection sub-area can correspond to a specific driving mode of the all-terrain vehicle 100.

[0042] In one embodiment, as Figure 5 shown, a plurality of mode selection sub-areas are evenly arranged around the rotation center line C, and each mode selection sub-area has a central angle coinciding with the rotation center line C. When the knob 321 rotates by a set angle each time, the conductive terminal can trigger different mode selection sub-areas to perform the selection of the driving mode. The mode selection area is Figure 5 the area Z formed by two red circular dotted lines in n . Among them, n is the number of mode selection areas. In the embodiment of the present application, n = 12.

[0043] In one embodiment, as Figure 5 shown, the area on the circuit board 3233 not covered by the conductive sheet 3234 and the area covered by the conductive sheet 3234 together constitute 12 mode selection sub-areas, and the 12 mode selection sub-areas are evenly distributed around the rotation center line C. Each mode selection sub-area corresponds to a specific central angle, which is 30° in this embodiment, and these central angles are evenly arranged around the rotation center line C.

[0044] It should be noted that the 12 mode selection sub-areas can correspond to three modes. Among them, mode sub-areas z1 and z7, z4 and z 10 correspond to the first mode; mode sub-areas z2 and z8, z5 and z 11 correspond to the second mode; mode sub-areas z3 and z9, z6 and z 12 correspond to the third mode.

[0045] In one embodiment, as Figure 6As shown in the figure, a first connection point 3233a and a second connection point 3233b are provided on the circuit board 3233. Among them, the side of the circuit board 3233 covered with the first metal sheet 3234a and the second metal sheet 3234b is the front side of the circuit board 3233; the first connection point 3233a and the second connection point 3233b are located on the back side of the circuit board 3233. The mode switching circuit 323 includes a first conductive terminal 3231 and a second conductive terminal 3232, and the first conductive terminal 3231 and the second conductive terminal 3232 are distributed on opposite sides of the rotation center line C. There are four second metal sheets 3234b, and the four second metal sheets 3234b are divided into two groups, namely the first group and the second group. Both the first group and the second group include two second metal sheets 3234b, and the area of the second metal sheets 3234b in the first group is larger than the area of the second metal sheets 3234b in the second group. The first connection point 3233a is connected to two adjacent second metal sheets 3234b in the first group, and the second connection point 3233b is connected to two adjacent second metal sheets 3234b in the second group. Among them, the first connection point 3233a is point A on the back side of the circuit board 3233, and the second connection point 3233b is point B on the back side of the circuit board 3233.

[0046] When the knob 321 rotates, the first contact 3231a of the first conductive terminal 3231 is always in contact with the first metal sheet 3234a, and the second contact 3231b of the first conductive terminal 3231 is in contact with the second metal sheet 3234b or the area not covered by the second metal sheet 3234b. When the second contact 3231b of the first conductive terminal 3231 is in contact with one of the second metal sheets 3234b, an electrical connection will be formed with the first connection point 3233a or the second connection point 3233b connected to the second metal sheet 3234b. Similarly, when the first contact 3232a of the second conductive terminal 3232 is always in contact with the first metal sheet 3234a and the second contact 3232b of the second conductive terminal 3232 is in contact with one of the second metal sheets 3234b, an electrical connection can also be formed with the first connection point 3233a or the second connection point 3233b corresponding to the second metal sheet 3234b. Based on the conduction conditions of the first connection point 3233a and the second connection point 3233b, corresponding control signals are generated. It should be noted that if the second contact 3231b of the first conductive terminal 3231 and the second contact 3232b of the second conductive terminal 3232 are both in contact with the area not covered by the second metal sheet 3234b, then neither the first connection point 3233a nor the second connection point 3233b is conducting, and corresponding control signals are generated.

[0047] Exemplarily, during the rotation of the knob 321, if the first conductive terminal 3231 is electrically connected to the first connection point 3233a corresponding to one of the second metal sheets 3234b, and the second conductive terminal 3232 is not electrically connected to the first connection point 3233a or the second connection point 3233b. At this time, only the first connection point 3233a is electrically connected, and a corresponding control signal is generated. If during the rotation of the knob 321, the first conductive terminal 3231 is electrically connected to the first connection point 3233a corresponding to one of the second metal sheets 3234b and the second conductive terminal 3232 is electrically connected to the second connection point 3233b corresponding to one of the second metal sheets 3234b, then at this time both the first connection point 3233a and the second connection point 3233b are electrically connected, and a corresponding control signal is generated. If during the rotation of the knob 321, the first conductive terminal 3231 is not electrically connected to the first connection point 3233a or the second connection point 3233b, and the second conductive terminal 3232 is also not electrically connected to the first connection point 3233a or the second connection point 3233b, then a control signal corresponding to the non - electrical connection of both the first connection point 3233a and the second connection point 3233b is generated.

[0048] In this embodiment, the change of this electrical connection relationship can generate different control signals, thereby realizing the switching of the driving modes of the all - terrain vehicle 100, which not only improves the accuracy of mode switching but also enhances the stability of the circuit.

[0049] In this embodiment, this design enables the rotation of the knob 321 to accurately control the electrical connection state of the circuit, thereby realizing the accurate switching of the driving modes of the all - terrain vehicle 100.

[0050] In one embodiment, as Figure 7 shown, the control module 31 includes an α pin and a β pin. The α pin is connected to the first connection point 3233a, and the β pin is connected to the second connection point 3233b. If the first connection point 3233a is electrically connected, the value corresponding to the α pin is 1; conversely, the value corresponding to the α pin is 0. If the second connection point 3233b is electrically connected, the value corresponding to the β pin is 1; conversely, the value corresponding to the β pin is 0.

[0051] When the first connection point 3233a is electrically connected, the value corresponding to the α pin is 1, indicating that this pin is in a high - level state; conversely, if the first connection point 3233a is not electrically connected, the value corresponding to the α pin is 0, indicating that this pin is in a low - level state. Similarly, when the second connection point 3233b is electrically connected, the value corresponding to the β pin is 1, indicating high - level; if the second connection point 3233b is not electrically connected, the value corresponding to the β pin is 0, indicating low - level.

[0052] In this embodiment, in this way, the control module 31 can accurately determine the specific state of the mode switching circuit 323 according to the level states of the α pin and the β pin, and further determine the driving mode in which the all-terrain vehicle 100 is currently located.

[0053] In one embodiment, a plurality of mode selection sub-regions are evenly arranged around the rotation center line C, and each mode selection sub-region has a central angle that coincides with the rotation center line C. When the knob 321 rotates by a set angle each time, the conductive terminal can trigger different mode selection sub-regions to perform the selection of the driving mode.

[0054] The uniform layout of the plurality of mode rotation sub-regions can ensure that during the rotation of the knob 321, different mode selection sub-regions can be triggered at equal angular intervals. It should be noted that when the knob 321 rotates by a set angle each time, the conductive terminal will contact the next mode selection sub-region, thereby triggering the corresponding control signal to realize the selection of the driving mode.

[0055] In this embodiment, this design makes the switching of the driving mode both precise and uniform. The user can select different driving modes by rotating the knob in fixed angle increments, improving the convenience and accuracy of operation.

[0056] In one embodiment, each rotation of the knob 321 rotates 30 degrees, and 12 mode selection sub-regions are provided for the switching between the first mode, the second mode, and the third mode; the first mode is the normal mode, the second mode is the sports mode, and the third mode is the track mode.

[0057] Specifically, when the knob 321 rotates once, the rotation angle is 30 degrees, and the conductive terminal will sequentially trigger different mode selection sub-regions. The 12 mode selection sub-regions respectively correspond to three different driving modes. The first mode is the normal mode, which is suitable for daily driving; the second mode is the sports mode, which is suitable for driving scenarios that require higher power output; the third mode is the track mode, which is suitable for track driving and provides the strongest power output.

[0058] In this embodiment, in this way, the user can select the required driving mode among 12 different mode selection sub-regions through the knob switch module 32, realizing flexible adjustment of the performance of the all-terrain vehicle 100.

[0059] In one embodiment, when the knob 321 rotates clockwise, it sequentially switches in a cycle of the first mode - the second mode - the third mode - the first mode, and when the knob 321 rotates counterclockwise, it sequentially switches in a cycle of the first mode - the third mode - the second mode - the first mode.

[0060] When the knob 321 is rotated clockwise, the driving mode will be switched in a reciprocating cycle in the order of the first mode-the second mode-the third mode-the first mode. It should be noted that starting from the first mode, the mode is switched to the second mode by rotating clockwise once; the mode is switched to the third mode by rotating clockwise once again; the mode is returned to the first mode by continuing to rotate clockwise, and the cycle continues.

[0061] On the contrary, when the knob 321 is rotated counterclockwise, the driving mode will be switched in the order of the first mode-the third mode-the second mode-the first mode. That is, starting from the first mode, rotate counterclockwise once, the mode will be switched to the third mode; rotate counterclockwise once again, switch to the second mode; continue to rotate counterclockwise, it will return to the first mode, and so on.

[0062] In this embodiment, this design allows the user to flexibly switch between different driving modes through the knob switch module 32 to meet different driving needs.

[0063] In one embodiment, after the knob 321 rotates a first angle, the control module 31 can determine the next driving mode to be switched by the all-terrain vehicle 100 based on the recorded current driving mode and the values corresponding to the rotated α pin and β pin; wherein the first angle is an integer multiple of 30 degrees.

[0064] Specifically, the control module 31 can record the current driving mode. When the knob 321 rotates a first angle (the angle is an integer multiple of 30 degrees), the level states of the α pin and the β pin will change accordingly. The control module 31 can determine the next driving mode that the user wants to switch to by detecting the level states of the two pins and combining the information of the current driving mode.

[0065] For example, if the current mode is the first mode, after the knob 321 is rotated 30 degrees clockwise, the level states of the α pin and the β pin will instruct the control module 31 to switch to the second mode.

[0066] In this embodiment, this design makes the switching of driving modes both precise and reliable, ensuring the accuracy of user operation and the performance of the all-terrain vehicle 100.

[0067] In one embodiment, when the knob 321 is rotated clockwise, the driving mode of the ATV 100 can be switched from the first mode to the second mode and from the second mode to the third mode, and the driving mode of the ATV 100 is not cycled when switched to the third mode.

[0068] When the knob 321 rotates clockwise, the driving mode of the all-terrain vehicle 100 can be switched in a specific order. The driving mode can be switched from the first mode to the second mode, and then from the second mode to the third mode. It should be noted that the switching of the driving mode is one-way, that is, when rotating clockwise, the driving mode will sequentially change from the first mode to the second mode, and then to the third mode. When the driving mode is switched to the third mode, it will not continue to cycle back to the first mode. That is to say, when rotating clockwise, once the third mode is reached, continuing to rotate clockwise will not change the driving mode.

[0069] When the knob 321 rotates counterclockwise, the driving mode of the all-terrain vehicle 100 can be switched from the third mode to the second mode and from the second mode to the first mode, and when the driving mode of the all-terrain vehicle 100 is switched to the first mode, it does not cycle.

[0070] It should be noted that the switching of the driving mode is one-way, that is, when rotating counterclockwise, the driving mode will sequentially change from the third mode to the second mode, and then to the first mode. When the driving mode is switched to the first mode, it will not continue to cycle back to the third mode. That is to say, when rotating counterclockwise, once the first mode is reached, continuing to rotate counterclockwise will not change the driving mode.

[0071] In one embodiment, as Figure 8 shown, taking the knob 321 rotating clockwise and starting from the first mode as an example, the switching steps of the driving mode of the all-terrain vehicle 100 are as follows:

[0072] Step S801: The current driving mode is the first mode;

[0073] Step S802: Determine whether the knob 321 rotates clockwise;

[0074] If the knob 321 rotates clockwise, execute step S803; if the knob 321 rotates counterclockwise, execute step S801.

[0075] Step S803: Switch the driving mode to the second mode;

[0076] Step S804: Determine whether the knob 321 rotates clockwise;

[0077] If the knob 321 rotates clockwise, execute step S805; if the knob 321 rotates counterclockwise, execute step S801.

[0078] Step S805: Switch the driving mode to the third mode;

[0079] Step S806: Determine whether the knob 321 rotates clockwise;

[0080] If the knob 321 is rotated clockwise, step S807 is executed; if the knob 321 is rotated counterclockwise, step S803 is executed.

[0081] Step S807: Maintain the third mode.

[0082] In this embodiment, this design ensures the stability and predictability of the driving mode, enabling the user to select between different driving modes according to their driving needs without worrying about accidental cyclic switching of the modes.

[0083] In one embodiment, as Figure 9 shown, the red line represents the first mode, the green line represents the second mode, and the yellow line represents the third mode; after the knob 321 rotates by a second angle, the control module 31 determines the rotation direction of the knob 321 based on the recorded current driving mode and the values corresponding to the α and β pins before and after the knob 321 rotates by the second angle; the control module 31 can determine the driving mode that the all-terrain vehicle 100 needs to switch to according to the rotation direction of the knob 321; wherein, the second angle is an integer multiple of 30 degrees.

[0084] Specifically, the control module 31 can determine whether the knob 321 rotates clockwise or counterclockwise by comparing the changes in the level states of the α and β pins before and after rotation.

[0085] Exemplarily, when the user rotates the knob 321 by a second angle, the control module 31 needs to determine the rotation direction based on the recorded current driving mode and the values of the α and β pins before and after rotation, and decide whether to switch the driving mode. Before rotation, the values of the α and β pins are 0 and 0 respectively. After the knob 321 rotates, due to the structural design of the mode switching circuit 323, the contact situation between the conductive terminal and the second metal sheet 3234b changes. Assume that in this case, after rotation, the value of the α pin becomes 1 and the value of the β pin becomes 0. By comparing the pin value changes before (α = 0; β = 0) and after (α = 1; β = 0) rotation, the control module 31 can determine that the driving mode changes from the first mode to the third mode and can determine that the rotation direction of the knob 321 is counterclockwise. According to the preset logic, if the current driving mode is the first mode and the rotation direction is counterclockwise, the control module 31 does not execute the driving mode switch but maintains the driving mode in the first mode.

[0086] Exemplarily, before rotation, the values of the α pin and the β pin are 0 and 0 respectively. After the knob 321 rotates, due to the structural design of the mode switching circuit 323, the contact situation between the conductive terminal and the second metal sheet 3234b changes. Assuming that in this case, after rotation, the value of the α pin becomes 1 and the value of the β pin becomes 1. By comparing the changes in the pin values before rotation (α = 0; β = 0) and after rotation (α = 1; β = 1), the control module 31 can determine that the driving mode changes from the first mode to the second mode and can determine that the rotation direction of the knob 321 is clockwise. According to the preset logic, if the current driving mode is the first mode and the rotation direction is clockwise, the control module 31 switches the driving mode to the second mode.

[0087] In this embodiment, this precise control logic ensures that the switching of the driving mode is both accurate and in line with the user's operation intention.

[0088] In one embodiment, if the current driving mode is the first mode and the rotation direction of the knob 321 is counterclockwise rotation, the control module 31 maintains the driving mode as the first mode and assigns the values corresponding to the α pin and the β pin after rotation to the first mode; if the current driving mode is the first mode and the rotation direction of the knob 321 is clockwise rotation, the control module 31 switches the driving mode to the second mode.

[0089] Exemplarily, assume that the current driving mode is the first mode. At this time, the value of the α pin is 0 and the value of the β pin is also 0. When the user rotates the knob 321 counterclockwise by 30 degrees, the control module 31 detects that the rotation direction is counterclockwise. According to the preset logic, the control module 31 maintains the driving mode as the first mode and reassigns the values of the α pin and the β pin after rotation to the values corresponding to the first mode, that is, α = 0 and β = 0.

[0090] On the contrary, assume that the current driving mode is the first mode. At this time, the value of the α pin is 0 and the value of the β pin is also 0. When the user rotates the knob 321 clockwise by 30 degrees, the control module 31 detects that the rotation direction is clockwise. According to the preset logic, the control module 31 switches the driving mode to the second mode and updates the value of the α pin to 1 and the value of the β pin to 1.

[0091] If the current driving mode is the third mode and the rotation direction of the knob 321 is counterclockwise rotation, the control module 31 switches the driving mode to the second mode; if the current driving mode is the third mode and the rotation direction of the knob 321 is clockwise rotation, the control module 31 maintains the driving mode as the third mode and assigns the values corresponding to the α pin and the β pin after rotation to the third mode.

[0092] Exemplarily, assume that the current driving mode is the third mode. At this time, the value of the α pin is 1 and the value of the β pin is 0. When the user rotates the knob 321 counterclockwise by 30 degrees, the control module 31 detects that the rotation direction is counterclockwise. According to the preset logic, the control module 31 switches the driving mode to the second mode and updates the value of the α pin to 1 and the value of the β pin to 1.

[0093] Conversely, assume that the current driving mode is the third mode. At this time, the value of the α pin is 1 and the value of the β pin is 0. When the user rotates the knob 321 clockwise by 30 degrees, the control module 31 detects that the rotation direction is clockwise. According to the preset logic, the control module 31 maintains the driving mode as the third mode and reassigns the values of the α and β pins after rotation to the values corresponding to the third mode, that is, α = 1 and β = 0.

[0094] In this embodiment, such a design ensures that the switching of the driving mode not only conforms to the user's operation but also avoids cyclic switching in the highest or lowest mode, improving the stability and predictability of driving.
