[0002] Knob switch is a kind of switch form more common in daily life, and different working conditions are achieved by rotating knob to operate equipment. The knob switch on the car is generally used to adjust the volume, switch the car sport mode and other various function settings. The current shift knob operating mode basically adopts encoder or self-made track structure to realize, and the spring is added to the stop pin to slide on the corresponding track surface to realize the operation hand feeling. However, this design has obvious shortcomings: after long time use, the friction between track and stop pin can cause wear, and then affect the accuracy and consistency of hand feeling, even make knob lose resistance and grading feeling;And the shift knob of this structure has large noise when shifting, and the hand feeling is relatively harsh, which cannot bring better experience to users. SUMMARY

[0003] The utility model aims at overcoming the defects of prior art, and provides a shift knob, which realizes rotation hand feeling by magnetic force change, so as to solve the problems existing in traditional mechanical stop switch.

[0004] The technical scheme of the utility model discloses a shift knob, which comprises a shell seat and a knob part, a PCB board is arranged in the shell seat, the knob part can rotate relative to the shell seat, a plurality of fixed magnets are arranged on the shell seat in a circumferential direction, each fixed magnet surrounds a fixed magnetic ring A, a plurality of moving magnets are arranged on the knob part in a circumferential direction, each moving magnet surrounds a rotating magnetic ring A, the rotating magnetic ring A and the fixed magnetic ring A are arranged in an inner-outer mode, and the moving magnets and the fixed magnets are positioned by opposite poles.

[0006] By adopting the above technical scheme, the shift knob of the utility model realizes hand feeling feedback by the change of magnetic attraction, improves product reliability, and significantly prolongs service life. By adopting the magnetic attraction positioning mode of fixed magnets and moving magnets, stable rotation and positioning of the knob part on the shell seat are realized, when the knob part rotates relative to the shell seat, the opposite poles of the moving magnets and the fixed magnets attract each other, so that the knob part can stably stay between different stops, and the knob can feel the change of magnetic attraction force during rotation, so as to provide clear and consistent stop hand feeling. Avoid the wear problem of traditional track structure, and ensure the long-term stability and accuracy of hand feeling.

[0007] In addition, the knob also integrates a press confirmation function. By setting a button in the middle of the knob part and a micro switch on the PCB board, the user can confirm the selection by pressing the middle button after rotating to the appropriate gear position. This design not only improves the convenience of user operation, but also realizes the conduction of electrical signals through the micro switch, ensuring the accurate execution of the function.

[0008] Further settings of the utility model are: the number of the fixed magnets and the moving magnets is equal or in a multiple relationship.

[0009] With the above further settings, this design further optimizes the effect of magnetic positioning. When the number of fixed magnets and moving magnets is equal, it can ensure that each moving magnet can form stable opposite poles with the corresponding fixed magnet, making the knob part stay more firmly between each gear. When they are in a multiple relationship, they can provide more diverse magnetic changes, so that the knob can feel more delicate feedback during rotation, improving the accuracy of operation and user experience. In addition, this number relationship setting also enhances the adaptability and flexibility of the product, which can be adjusted and optimized according to different application scenarios and needs.

[0013] With the further arrangement, the knob inner shell can be stably arranged in the accommodating cavity, and the stable and accurate rotation is ensured by the cooperation of the bearing and the outer periphery of the main shaft. The moving magnet at the lower end of the knob inner shell interacts with the fixed magnet on the main shaft, so that the magnetic attraction effect is realized, and the stability and reliability of the knob operation are enhanced. The design of the rotating cap fully considers the use habit of the user, so that the user can easily hold and rotate the knob, and the exposed part outside the accommodating cavity also provides good visual feedback.

[0015] With the further arrangement, the space between the knob inner shell and the main shaft is ingeniously utilized to form the annular space accommodating the bearing. The first boss and the first clamping leg on the main shaft jointly support and press the inner ring of the bearing, and the second boss and the second clamping leg on the knob inner shell correspondingly support and press the outer ring of the bearing. The double support structure greatly enhances the stability of the bearing, thereby ensuring the stability and accuracy of the rotation of the knob. The slope design of the clamping leg on the corresponding side of the annular space, when the bearing is pressed against the clamping leg, the slope on the bearing is in contact with the clamping leg, so that the clamping leg is extruded outward by the bearing, and the plurality of movable openings arranged on the circumference of the main shaft and the knob inner shell provide a space for the clamping leg to move, and after the bearing passes through the clamping leg, the clamping leg is reset to be arranged on the bearing, thereby facilitating the installation of the bearing.

[0016] With the further arrangement, the button comprises a pressing rod and a pressing cap arranged on the upper end of the pressing rod, the pressing rod is arranged in the main shaft and is in sliding cooperation with the inner ring of the main shaft through the vertical guide rail and guide groove, the lower end of the pressing rod is provided with a touch block pressing the micro-motion switch, and the pressing cap is exposed outside the main shaft.

[0017] With the further setting, the design of the pressing cap is not only convenient for user operation, but also increases the beauty of the gear shifting knob. When the user needs to shift gears, only needs to press the pressing cap, the pressure rod will slide down along the guide rail and guide groove in the main shaft until the contact block contacts the micro switch. This design makes the gear shifting operation more simple and intuitive, and the sliding cooperation ensures the stability and reliability of the gear shifting process, which can effectively prevent the pressure rod from deviating or shaking.
