Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts, and specifically relates to a combination gear switch. Background Technology

[0002] In existing vehicle control systems, gear shifting typically involves multiple independent functional modules, including automatic / manual driving mode switching, gear shifting (such as drive, reverse, and parking gears), upshifting / downshifting in manual mode, and adjusting the energy recovery level in automatic mode. In traditional designs, these functions are often implemented separately through multiple physical switches or operating mechanisms: for example, a knob or lever is used to switch between automatic and manual modes; another separate gear selector or button group is used for gear selection; and in manual mode, additional "+ / -" buttons or paddles are needed for incremental upshifting and downshifting; furthermore, adjusting the energy recovery level in automatic mode may require a separate roller, slider, or button.

[0003] This decentralized layout not only occupies a significant amount of interior space and increases the complexity of human-machine interaction, but also easily leads to user misoperation. More importantly, the functional components are isolated from each other, lacking coordinated control logic, making it difficult to implement a mechanism for intelligently switching input signal types based on the current operating mode. For example, the same handle cannot reuse its rotational motion to trigger "gear shifting" or "energy recovery adjustment" in different modes; additional hardware must be used to distinguish the intent, resulting in system redundancy, increased costs, and reduced reliability.

[0004] Furthermore, while existing rotary gear shifting devices can achieve multi-gear switching, they generally suffer from problems such as vague positioning feel and inaccurate signal triggering. Some solutions use a purely mechanical locking structure, lacking effective linkage with electronic signal detection, resulting in a disconnect between the timing of gear shift signal generation and the user's actual operating intention; while other solutions, although introducing Hall sensors to detect angles, do not link them with mode status, making it impossible to distinguish the semantic differences of the same rotational action in different modes.

[0005] Therefore, there is an urgent need for a combination gear switch that is highly integrated, compact in structure, and can dynamically reuse the semantics of handle actions according to the operation mode, in order to solve the technical problems of functional separation, cumbersome operation, rigid signal recognition logic, and poor human-computer interaction experience in the existing technology. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a combined gear switch in view of the current situation of the prior art.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a combined gear switch is proposed, comprising: a housing;

[0008] A handle, which is movably mounted on the housing and can rotate relative to the housing;

[0009] A knob, which is rotatably mounted on the handle;

[0010] A mode switching button is movably disposed on the knob and is limitedly connected to the knob. The mode switching button is used to trigger the switching between automatic mode and manual mode.

[0011] The signal processing unit includes:

[0012] A first signal receiver is disposed inside the housing and arranged opposite to one end of the handle, for detecting the rotation angle of the handle and generating a corresponding control signal according to the current operating mode;

[0013] A second signal receiver is disposed inside the handle and arranged opposite to the knob, for detecting the rotation angle of the knob and generating a shift signal;

[0014] A third signal receiver is disposed inside the handle and is used to detect changes in the position of the mode switching button and generate a mode switching signal.

[0015] When the mode switching button triggers manual mode, the handle rotates in the first direction, triggering the first signal receiver to generate a manual up / down signal;

[0016] When the mode switching button triggers the automatic mode, the handle rotates in the second direction, triggering the first signal receiver to generate an energy recovery signal.

[0017] In the aforementioned combination gear switch, a connecting bracket is fixed inside the handle, the second signal receiver is a first Hall sensor fixed on the connecting bracket, and a mounting groove is provided on the knob, with a first magnet fixed inside the mounting groove;

[0018] When the knob is rotated relative to the handle, the first magnet rotates synchronously with the knob, causing the first Hall sensor to generate a shift signal by detecting changes in the magnetic field.

[0021] In one of the above-mentioned combined gear switches, conductive rubber is provided on the first circuit board, and the conductive rubber covers the surface of the contact switch;

[0022] When the mode switching button is pressed, the trigger rod compresses the conductive rubber to make it conduct the circuit and generate a mode switching signal;

[0023] When the external force is removed, the conductive rubber elastically resets and pushes the trigger rod back to its original position, causing the mode switching button to return to its initial position.

[0024] In one of the above-mentioned combined gear switches, the knob is provided with a first mounting hole; the end of the connecting bracket is provided with a deformation part, and a snap-fit ​​flange is formed on the outer side of the deformation part;

[0025] When the connecting bracket is inserted into the first mounting hole, the deformable part is compressed and contracts, and then expands elastically after passing through the first mounting hole, so that the snap-fit ​​flange snaps into the end face of the first mounting hole to restrict the knob from moving axially.

[0026] In one of the aforementioned combined gear switches, the connecting frame is provided with a second mounting hole; a retractable first positioning member is provided in the second mounting hole, and a first elastic member is provided between the first positioning member and the bottom wall of the second mounting hole; a plurality of first positioning grooves are provided circumferentially on the inner wall of the knob; the first positioning member can be alternately engaged in any of the first positioning grooves under the action of the first elastic member to realize the gear positioning of the knob.

[0027] In one of the aforementioned combined gear switches, the connecting frame is provided with a third mounting hole;

[0028] The third mounting hole is provided with a retractable second positioning member, and a second elastic member is provided between the second positioning member and the bottom wall of the third mounting hole;

[0029] The inner wall of the knob is provided with multiple inclined surfaces spaced apart circumferentially;

[0030] When the knob is turned, the inclined surface pushes the second positioning member to move inward against the elastic force of the second elastic member;

[0031] When the external force applied to the knob is removed, the second positioning member slides along the inclined plane and returns to its initial position under the elastic force of the second elastic member;

[0032] Specifically, the second signal receiver generates a shift signal only when the knob is rotated to the set gear angle.

[0033] In the aforementioned combination gear switch, a handle frame is fixed inside the handle; a rotating seat is provided inside the housing, and the rotating seat is rotatably mounted inside the housing along the second direction; the handle frame is rotatably connected to the rotating seat; a mounting platform is fixed at the end of the handle frame, and a second magnet is provided on the mounting platform; the signal processing unit includes a second circuit board fixed inside the housing; the first signal receiver is a second Hall sensor disposed on the second circuit board;

[0034] When in manual mode, the handle rotates in the first direction, causing the second magnet to move relative to the second Hall sensor, generating a manual up / down signal;

[0035] When in automatic mode, the handle and the rotating base rotate synchronously in the second direction, driving the second magnet to move and causing the second Hall sensor to generate an energy recovery signal.

[0036] In one of the above-mentioned combination gear switches, a third positioning member is rotatably provided at the end of the rotating base away from the handle frame; a plurality of second positioning grooves are provided circumferentially on the inner wall of the housing; the third positioning member can be alternately engaged into any of the second positioning grooves;

[0037] When the handle is rotated to a set angle in automatic mode, the third positioning component engages with the corresponding second positioning slot, locking the energy recovery gear.

[0038] In one of the above-mentioned combined gear switches, the rotating base is provided with a mounting cavity; the third positioning member is slidably disposed in the mounting cavity, and a third elastic member is provided between the third positioning member and the bottom wall of the mounting cavity;

[0039] When the rotating seat rotates, the third positioning member is squeezed into the mounting cavity by the side wall of the second positioning groove;

[0040] When rotated to the next second positioning groove, the third elastic member pushes the third positioning member to extend and engage with the second positioning groove.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] (1) By integrating the handle, knob and mode switching button together, and using the first signal receiver, the second signal receiver and the third signal receiver to monitor their actions respectively, different semantic recognition of the same rotation action of the handle in automatic mode and manual mode is realized. This design significantly improves the integration of operation, solves the problem that the traditional solution requires multiple independent switches to realize gear shifting, mode switching and energy recovery adjustment, simplifies the human-machine interaction logic, reduces the risk of misoperation, and also saves interior space.

[0043] (2) A stable mounting base is provided for the first Hall sensor through the connecting bracket, ensuring that the magnetic field changes generated when the knob is rotated can be accurately captured, thereby generating accurate shift signals. This method avoids the problems of easy wear and poor contact of traditional mechanical contacts, further improving the stability and durability of the system.

[0044] (3) The third signal receiver is designed as a contact switch integrated on the first circuit board and linked to it via a trigger rod on the mode switching button. This design is not only compact and responsive, but also facilitates sharing the same circuit platform with the second signal receiver (i.e., the first Hall sensor). This layout is conducive to the miniaturization and modular integration of the signal processing unit, significantly improving overall assembly efficiency and the stability of the electrical system.

[0045] (4) By setting conductive rubber on the surface of the contact switch, not only is flexible pressing and silent operation achieved, improving the button feel, but it can also automatically complete the reset action after pressing, relying on its elasticity, without the need for an additional reset mechanism. This design simplifies the overall structure while effectively ensuring the reliability of mode switching operation and long-term durability. Attached Figure Description

Detailed Implementation

[0058] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0059] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0060] like Figures 1 to 11 As shown, the present invention provides a combined gear switch, including a housing 100, a handle 200, a knob 300, a mode switching button 400, and a signal processing unit 500.

[0061] Specifically, the housing 100 serves as the support and mounting structure for the combined gear switch. In one embodiment, it has an overall square structure and consists of threaded upper and lower cover plates and a middle housing 100. This design facilitates the installation of the signal processing unit 500 and the handle 200.

[0062] The handle 200 is movably mounted on the housing 100 and can rotate relative to the housing 100. In automatic mode, the handle 200 serves as a trigger unit for the energy recovery signal, and in manual mode, it serves as a trigger unit for shifting gears.

[0063] The knob 300 is rotatably mounted on the handle 200 and serves as a trigger unit for gear shifting. In one example, the combination gear switch includes D (Drive), N (Neutral), and R (Reverse) gears to control the corresponding driving states of the vehicle. Initially, the knob 300 is in the N position, keeping the vehicle in neutral.

[0064] The mode switch button 400 is located on the knob 300 and can be moved to trigger switching between automatic and manual modes. It is connected to the limit switch of the knob 300 to ensure stability during mode switching.

[0065] The signal processing unit 500 includes:

[0066] The first signal receiver 510 is housed inside the housing 100 and arranged opposite to one end of the handle 200. It is used to detect the rotation angle of the handle 200 and generate a corresponding control signal according to the current operating mode.

[0067] The second signal receiver 520 is placed inside the handle 200 and arranged opposite to the knob 300, and is used to detect the rotation angle of the knob 300 and generate a shift signal.

[0068] The third signal receiver 530, also located inside the handle 200, is used to detect changes in the position of the mode switching button 400 and generate a mode switching signal.

[0069] When the mode switching button 400 activates the manual mode, the handle 200 rotates in the first direction, causing the first signal receiver 510 to generate a manual up / down gear signal.

[0070] In automatic mode, when the handle 200 is rotated in the second direction, it will trigger the first signal receiver 510 to generate an energy recovery signal.

[0071] This design integrates the handle 200, knob 300, and mode switching button 400 together, and uses the first signal receiver 510, the second signal receiver 520, and the third signal receiver 530 to monitor their movements, thereby achieving different semantic recognition of the same rotation movement of the handle 200 in automatic and manual modes.

[0072] In manual mode, rotating the lever 200 is used to perform gear shifting; while in automatic mode, it is used to adjust the energy recovery intensity. This design significantly improves operational integration, solving the problem of traditional solutions requiring multiple independent switches for gear shifting, mode switching, and energy recovery adjustment. It simplifies human-machine interaction logic, reduces the risk of misoperation, and also saves interior space.

[0073] It is worth mentioning that a connecting bracket 210 is fixed inside the handle 200, and the second signal receiver 520 is a first Hall sensor mounted on the connecting bracket 210. The knob 300 has a mounting slot 310, in which a first magnet is fixed. When the knob 300 rotates relative to the handle 200, the first magnet rotates synchronously with the knob 300, enabling the first Hall sensor to generate a shift signal by detecting changes in the magnetic field.

[0074] The connecting bracket 210 and the handle 200 are preferably connected by a threaded connection. In one embodiment, the handle 200 is a hollow cylinder, and the connecting bracket 210 is installed in the internal space of the handle 200 by bolts. This design uses a first Hall sensor in conjunction with a first magnet on the knob 300 to form a non-contact angle detection structure, thereby effectively improving the reliability and service life of the shift signal detection.

[0075] As the internal support frame of the handle 200, the connecting bracket 210 provides a stable mounting base for the first Hall sensor, ensuring that the magnetic field changes generated when the knob 300 is rotated can be accurately captured, thereby generating accurate shift signals. This method avoids the problems of easy wear and poor contact of traditional mechanical contacts, further improving the stability and durability of the system.

[0076] The signal processing unit 500 includes a first circuit board 540 disposed on the connecting frame 210; a first Hall sensor is electrically connected to the first circuit board 540; a third signal receiver 530 is a contact switch disposed on the first circuit board 540; a mode switching button 400 is provided with a trigger rod 410, which extends into the area of ​​the connecting frame 210; when the mode switching button 400 is pressed, the trigger rod 410 contacts and engages with the contact switch, thereby generating a mode switching signal.

[0077] The third signal receiver 530 is designed as a contact switch integrated on the first circuit board 540 and linked to it via a trigger rod 410 on the mode switching button 400. This design not only results in a compact structure and rapid response but also facilitates sharing the same circuit platform with the second signal receiver 520 (i.e., the first Hall sensor). This layout promotes the miniaturization and modular integration of the signal processing unit 500, significantly improving overall assembly efficiency and the stability of the electrical system.

[0078] Preferably, the first circuit board 540 is provided with conductive rubber 550, which covers the surface of the contact switch. When the mode switching button 400 is pressed, the trigger rod 410 presses the conductive rubber 550, causing it to deform and conduct the circuit, thereby generating a mode switching signal; when the external force is removed, the conductive rubber 550 returns to its original position due to its elasticity, and pushes the trigger rod 410 back to its original position, causing the mode switching button 400 to return to its initial position.

[0079] By incorporating conductive rubber 550 onto the surface of the contact switch, not only is flexible pressing and silent operation achieved, improving the button's feel, but the rubber also automatically resets after pressing, eliminating the need for an additional reset mechanism. This design simplifies the overall structure while effectively ensuring the reliability of mode switching operations and long-term durability.

[0080] To restrict the movement of the knob 300 along the rotation centerline (i.e., axial direction) while allowing it to rotate relative to the handle 200, this design provides a first mounting hole 320 on the knob 300; the end of the connecting bracket 210 is provided with a deformation portion 211, and a snap-fit ​​flange 212 is formed on the outer side of the deformation portion 211. When the connecting bracket 210 is inserted into the first mounting hole 320, the deformation portion 211 is compressed by the hole wall and contracts, and after passing through the first mounting hole 320, it expands due to its own elasticity, causing the snap-fit ​​flange 212 to snap onto the end face of the first mounting hole 320, thereby effectively restricting the axial movement of the knob 300.

[0081] In one embodiment, the deformation part 211 is formed by providing an opening slot at the end of the connecting frame 210. The engagement between the deformation part 211 at the end of the connecting frame 210 and the first mounting hole 320 of the knob 300 ensures reliable axial positioning of the knob 300, preventing it from accidentally dislodging due to vibration or operating force during use. Furthermore, this structure is easy to assemble—simply inserting the connecting frame 210 into the knob 300 achieves self-locking, significantly improving product assembly efficiency and overall structural stability.

[0082] In one embodiment, the connecting bracket 210 is provided with a second mounting hole 213; a retractable first positioning member 214 is provided in the second mounting hole 213, and a first elastic member 215 is provided between the first positioning member 214 and the bottom wall of the second mounting hole 213; a plurality of first positioning grooves 330 are provided circumferentially at intervals on the inner wall of the knob 300. Under the action of the first elastic member 215, the first positioning member 214 can be alternately engaged in any of the first positioning grooves 330, thereby realizing the gear positioning of the knob 300 during the gear shifting process.

[0083] The first elastic element 215 is preferably a spring, and the first positioning element 214 is preferably a pin-like structure. By cooperating with the first positioning groove 330 on the inner wall of the knob 300, the first positioning element 214 achieves precise mechanical positioning of multiple gears under the action of elastic force, providing the user with a clear "gear feel" when operating the knob 300 to shift gears, significantly improving the operating experience. Simultaneously, this mechanical positioning structure works in conjunction with the signal detection of the first Hall sensor (i.e., the second signal receiver 520) to ensure that the gear shift signal is generated only when the knob 300 is rotated to the preset gear angle, effectively avoiding accidental triggering of the gear shift command due to being in the middle position.

[0084] In another embodiment, the connecting frame 210 is provided with a third mounting hole;

[0085] The third mounting hole is provided with a retractable second positioning member 216, and a second elastic member is provided between the second positioning member 216 and the bottom wall of the third mounting hole;

[0086] The inner wall of the knob 300 is provided with multiple inclined surfaces 340 at intervals along the circumference;

[0087] When the knob 300 is rotated, the inclined surface 340 pushes the second positioning member 216 to move inward against the elastic force of the second elastic member;

[0088] When the external force applied to the knob 300 is removed, the second positioning member 216 slides along the inclined surface 340 and returns to its initial position under the elastic force of the second elastic member.

[0089] Specifically, the second signal receiver 520 generates a shift signal only when the knob 300 is rotated to the set gear angle.

[0090] It should be noted that the second signal receiver 520 only generates a shift signal when the knob 300 is rotated to the set gear angle, in order to ensure the accuracy of the control command.

[0091] The second elastic element is preferably a spring, and the second positioning element 216 is preferably a pin-like structure. The third mounting hole in this embodiment is structurally identical to the second mounting hole 213 in the previous embodiment (or shares the same mounting area), therefore it is not shown separately in the accompanying drawings. The engagement between the second positioning element 216 and the inclined surface 340 on the inner wall of the knob 300 allows the knob 300 to return to its initial position after the external force is removed, via the inclined surface 340.

[0092] Furthermore, a handle frame 220 is fixed inside the handle 200; a rotating seat 110 is provided inside the housing 100, which is rotatably mounted inside the housing 100 in a second direction; the handle frame 220 is rotatably connected to the rotating seat 110; a mounting platform 230 is fixed to the end of the handle frame 220, and a second magnet 240 is provided on the mounting platform 230; the signal processing unit 500 also includes a second circuit board 560 fixed inside the housing 100, and the first signal receiver 510 is a second Hall sensor disposed on the second circuit board 560.

[0093] When the system is in manual mode, the user moves the handle 200 along the first direction (e.g., ...). Figure 6 The handle frame 220 rotates in the up and down direction. At this time, the second magnet 240 moves relative to the second Hall sensor, and the second Hall sensor outputs the corresponding manual up / down signal accordingly.

[0094] When the system is in automatic mode, the handle 200 and the rotating base 110 move synchronously in the second direction (e.g., ...). Figure 6 The second magnet 240 rotates in the front-back direction, causing the second Hall sensor to generate an energy recovery intensity adjustment signal.

[0095] The rotatable connection between the rotating seat 110 and the housing 100 can be achieved by setting a rotating shaft on the rotating seat 110 and rotatably inserting the rotating shaft into the corresponding bearing hole or bracket of the housing 100; similarly, the rotatable connection between the handle frame 220 and the rotating seat 110 can also be achieved by setting a rotating shaft on the handle frame 220 and rotatably installing it in the mounting hole on the rotating seat 110.

[0096] The connection between the mounting platform 230 and the handle frame 220 can be achieved through snap-fit, threaded connection, or welding, depending on structural strength and assembly requirements. In this solution, refer to... Figure 6 The up-and-down rotation of the handle 200 is defined as the first direction, and the forward-and-backward rotation is defined as the second direction.

[0097] Through the linkage design of the handle frame 220, the rotating base 110, the second magnet 240, and the second Hall sensor, the same handle 200 can trigger manual shifting / decrease signals or energy recovery signals when rotated in different directions under different operating modes, truly realizing the intelligent reuse mechanism of "one handle for two uses".

[0098] This structure not only simplifies hardware configuration and avoids the drawbacks of having to set up two independent operating mechanisms in traditional solutions, but also significantly improves long-term reliability and durability through non-contact magnetic field detection.

[0099] The rotating base 110 has a rotatable third positioning member 120 at the end away from the handle frame 220; the inner wall of the housing 100 is provided with a plurality of second positioning grooves 130 spaced apart circumferentially; the third positioning member 120 can be alternately engaged in any of the second positioning grooves 130. When the handle 200 is rotated to a set angle in automatic mode, the third positioning member 120 will engage in the corresponding second positioning groove 130, thereby locking the energy recovery level.

[0100] In automatic mode, the third positioning element 120 on the rotating base 110 engages with the second positioning groove 130 on the inner wall of the housing 100 to physically lock the energy recovery level, ensuring that the handle 200 remains stably at the set angle and preventing accidental changes in the energy recovery level due to vehicle vibration or accidental contact. This improves the controllability and safety of energy recovery adjustment in automatic mode.

[0101] The rotating seat 110 has an internal mounting cavity; the third positioning member 120 is slidably mounted in the mounting cavity, and a third elastic member is provided between the third positioning member 120 and the bottom wall of the mounting cavity. When the rotating seat 110 rotates, the third positioning member 120 is squeezed into the mounting cavity by the side wall of the second positioning groove 130; when rotating to the next position of the second positioning groove 130, the third elastic member pushes the third positioning member 120 out and into the second positioning groove 130.

[0102] The third elastic element is preferably in the form of a spring. Under the action of the third spring, the third positioning element 120 can automatically extend and retract, allowing it to smoothly pass over the protruding area between the second positioning slots 130 during the rotation of the rotating seat 110, and automatically engage when it reaches the next slot, realizing the "self-alignment" and "self-locking" of the energy recovery gear. This structure requires no external drive, operates smoothly and reliably, significantly improves the feel and positioning accuracy of gear switching, and enhances the durability of the system and the user experience.

[0103] The shifting procedure in this scheme is as follows:

[0104] 1. Knob 300 shifting operation (D / N / R gear selection)

[0105] The vehicle is initially in neutral (N) gear, with knob 300 in the middle position. When the driver rotates knob 300 clockwise or counterclockwise to the "D" (forward) or "R" (reverse) position, the first magnet mounted on the inner wall of knob 300 rotates synchronously. The first Hall sensor, fixed to the connecting bracket 210, detects the change in the direction of the magnetic field and outputs the corresponding shift signal when knob 300 reaches the preset gear angle (corresponding to D, N, or R gear). Finally, the vehicle control system receives this signal and executes the corresponding forward, neutral, or reverse command.

[0106] II. Gear Shifting Operations After Switching from Automatic to Manual Mode

[0107] The user enters manual mode by pressing the mode switching button 400 on top of the knob 300: the button moves down, causing the trigger lever 410 to press against the conductive rubber 550 on the first circuit board 540, closing the contact switch. The third signal receiver 530 then generates a manual mode switching signal, and the system switches to manual shifting mode. In this mode, the driver turns the handle 200 in a specific direction (e.g., forward or backward). The handle frame 220 causes the second magnet 240 at its end to move relative to the second Hall sensor inside the housing 100. The Hall sensor (i.e., the first signal receiver 510) detects the change in magnetic field and, combined with the current "manual mode" state, identifies the action as upshifting (+) or downshifting (-), thereby controlling the vehicle to shift gears sequentially (e.g., M1→M2→M3…). After releasing the button, the conductive rubber 550 elastically pushes the trigger lever 410 back to its original position, and the button automatically returns to its initial position, but the system remains in manual mode until the user switches back to automatic mode.

[0108] III. Energy Recovery Intensity Adjustment Operation in Automatic Mode

[0109] With the system in automatic mode, the driver can adjust the energy recovery intensity by swinging the handle 200 left and right (or in another direction perpendicular to gear shifting). At this time, the handle 200 causes the rotating seat 110 inside the housing 100 to rotate in the second direction, and the second magnet 240 at its end changes its relative position to the second Hall sensor. The first signal receiver 510 detects this angular change and, combined with the current "automatic mode" status, identifies it as an energy recovery adjustment command. When rotated to a preset angle (e.g., low, medium, and high recovery levels), the third positioning member 120 at the end of the rotating seat 110, under the action of the third spring, engages with the corresponding second positioning groove 130 on the inner wall of the housing 100, achieving gear locking. The vehicle's electronic control system adjusts the regenerative braking intensity of the motor accordingly to achieve different levels of energy recovery.

[0110] In summary, this solution provides a highly integrated and intelligently reusable combination gear switch. By organically integrating the handle 200, knob 300, and mode switching button 400, and combining multiple sensors and a precision positioning structure, it achieves differentiated semantic recognition of the same physical action of the handle 200 in different driving modes: in manual mode, it is used for upshifting / downshifting, and in automatic mode, it is used to adjust the energy recovery intensity. This design not only significantly reduces the space occupation and operational complexity caused by multiple independent switches in traditional solutions, but also, through innovative structures such as non-contact detection with Hall sensors and magnets, and a self-resetting button made of conductive rubber 550, balances the accuracy of signal recognition, the clarity of operation feel, and the reliability of long-term use.
