[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the related art, the knob electronic shifter (hereinafter referred to as GSM) usually rotates the operating knob to drive the magnet or grating on the knob bracket to rotate, and detects the rotation position or angle of the knob by sensing the change of the magnetic field through the hall switch arranged under the magnet or sensing the change of light through the photoelectric sensor. The shift feel is provided by the bullet head + curved block + elastic member.

[0030] Currently, the infinitely rotating electronic shifter mainly provides shifting force and feel through a fixed-position bullet head and a fixed-curvature curved block. This type of electronic shifter generally has the following problems:

[0031] 1. Once the structure of the knob electronic shifter is locked, the shift force feel is locked and cannot be adjusted.

[0032] 2. The only thing that can be adjusted is the elastic part, but this is only limited to the research and development stage. Once mass production is delivered to the customer, it will be impossible to provide the customer with a service to replace the elastic parts by disassembling them.

[0033] 3. Even if the elastic parts are replaced, it is impossible to meet the optimal feel requirements of every customer. Too many elastic parts are a huge challenge to production and after-sales control.

[0034] 4. The change of a single elastic part has limitations and cannot change the shape of the force-displacement curve (involving the suction feel, smoothness, gear clarity, etc. of the gear shift).

[0035] 5. The curved surface block is a mold part and cannot be adjusted once it is developed. If you want to increase the smoothness of gear shifting and the suction feeling, you need to re-open the mold, which will inevitably result in re-investment in the mold fee and increase the development cost.

[0036] In view of the above problems, the embodiment of the present invention optimizes the knob electronic shifter, and provides a knob electronic shifter and a vehicle, which can solve the problem in the related art that once the knob electronic shifter structure is locked, the shifting force feel is locked and cannot meet the feel requirements of different customers. In addition, this article focuses not on the implementation principle of gear position detection, but on a method for implementing adjustable shifting feel.

[0037] See also Figure 1 and Figure 2 As shown, a knob electronic shifter provided by an embodiment of the present invention may include: a housing 1; a curved block 2, which may be mounted on the housing 1, the surface of the curved block 2 having at least two contact curves 21, that is, the contact curve 21 is arranged on the surface of the curved block 2, which may be the bottom surface of the curved block 2, and the contact curve 21 is used to contact with the contact member 3, wherein each contact curve 21 may be bent and extended (for details, see Figure 3 and Figure 4As shown), and at least two of the contact curves 21 have different curvatures, that is, the curvature of each of the contact curves 21 is different, some of the curvatures are gentler, and some of the curvatures are steeper, wherein the curvature of these contact curves 21 can be designed according to actual needs; and a contact member 3, wherein the contact member 3 is mounted on the housing 1, and the contact member 3 is configured to be movable between at least two of the contact curves 21 relative to the curved surface block 2, that is, in actual design, the curved surface block 2 can be designed to be movable, so that after the curved surface block 2 is moved, the contact member 3 is aligned with one of the contact curves 21, or the contact member 3 can be designed to be movable, so that after the contact member 3 is moved, the contact member 3 is aligned with one of the contact curves 21 on the contact surface. A contact curve 21 is formed, so that the relative position between the contact piece 3 and the curved block 2 is adjustable, and then after the position is moved, the gear shifting feel is adjustable; in this embodiment, in actual use, it is preferred to design the curved block 2 to rotate around the axis of the knob, and the contact piece 3 can move along the radial direction of the knob to adjust the contact piece 3 to match different contact curves 21; and the contact piece 3 can move along any one of the contact curves 21 relative to the curved block 2. When the contact piece 3 is aligned with one of the contact curves 21, the contact piece 3 no longer moves along the radial and circumferential directions of the knob, and the curved block 2 can rotate around the axis of the knob, so that different positions of this contact curve 21 contact the contact piece 3 to achieve gear detection.

[0038] An embodiment of the present invention provides a knob electronic shifter. Since at least two contact curves 21 are arranged on the curved block 2, and the curvatures of at least two contact curves 21 are different, when the contact member 3 contacts different contact curves 21, the feel is different. Therefore, by adjusting the relative position of the contact member 3 and the curved block 2, the shift feel can be adjusted.

[0039] See also Figure 3 and Figure 4 As shown, the shapes of the two contact curves 21 are shown. Preferably, in this embodiment, the projections of the two contact curves 21 are concentric circles. Preferably, the contact member 3 is set to a bullet head structure. Of course, in other embodiments, it can also be set to a spherical or semi-spherical structure, or a rectangular parallelepiped structure.

[0040] Furthermore, a shift knob 11 may be provided on the housing 1. When the shift knob 11 is rotated, the curved block 2 rotates around the axis of the knob, and different positions of the corresponding contact curve 21 contact the contact member 3, that is, the contact member 3 moves along the contact curve 21 relative to the curved block 2.

[0041] See also Figure 2 As shown, in some embodiments, the two contact curves 21 may be connected by a variable curvature surface 22 , and the curvature of the variable curvature surface 22 changes continuously between the two contact curves 21 . That is, the curvature of one of the contact curves 21 can be a maximum value, and the curvature of the other contact curve 21 can be a minimum value, and the curvature of the variable curvature surface 22 between the two contact curves 21 gradually decreases from one side to the other side, wherein, along the direction in which the curvature of the variable curvature surface 22 gradually decreases, the variable curvature surface 22 can be regarded as countless contact curves 21, and the curvatures of these countless contact curves 21 decrease from a maximum value to a minimum value in sequence, so that a continuous change of curvature can be achieved between the two contact curves 21 with the maximum curvature and the minimum curvature, and the contact member 3 can move between the contact curve 21 with the maximum curvature and the contact curve 21 with the minimum curvature, and each movement to a position will correspond to a curvature value, and in the process of the contact member 3 moving between the contact curve 21 with the maximum curvature and the contact curve 21 with the minimum curvature, continuous and infinite adjustment of the shifting feel can be achieved.

[0042] Of course, in other embodiments, the contact curve 21 with the largest curvature and the contact curve 21 with the smallest curvature may also be contact curves 21 located in the middle, that is, a contact curve 21 with other curvatures may also be provided on the side where the two contact curves 21 are away from each other.

[0043] See also Figure 2 As shown, in some optional embodiments, the contact member 3 may be fixed with a magnet 4, wherein it can be understood here that the magnet 4 is indirectly fixed to the contact member 3 through other structural components, or it can be understood that the magnet 4 is directly fixed to the contact member 3; the housing 1 may be installed with a magnetic force adjustment coil 5 that cooperates with the magnet 4, that is, the magnet 4 can be used in conjunction with the magnetic force adjustment coil 5, and the magnetic force adjustment coil 5 can be configured to adjust the position of the contact member 3 by adjusting the current in the magnetic force adjustment coil 5. In this embodiment, the magnetic force adjustment coil 5 can generate a magnetic force on the magnet 4 after being energized, wherein the magnetic force can be an attractive force or a repulsive force, and the greater the current in the magnetic force adjustment coil 5, the greater the magnetic force generated, and the distance between the magnet 4, that is, the contact member 3 and the magnetic force adjustment coil 5 can be adjusted, thereby realizing the adjustment of the position of the contact member 3; when the position of the contact member 3 is adjusted, the contact curve 21 corresponding to the contact member 3 contacting the curved surface block 2 will also change accordingly, thereby adjusting the shift feel.

[0044] Of course, in other embodiments, the position of the contact member 3 may be adjusted by other mechanical means, such as manually moving the contact member 3 in a certain direction to move the contact member 3 to a different contact curve 21. Alternatively, the position of the curved block 2 may be adjusted to achieve the contact of the contact member 3 to a different contact curve 21.

[0045] See also Figure 2 As shown, in some embodiments, the magnetic force regulating coil 5 may be connected in series with an adjustable resistor 6, and the adjustable resistor 6 is configured to adjust the current in the magnetic force regulating coil 5 by adjusting the resistance of the adjustable resistor 6. That is, in this embodiment, the magnetic force regulating coil 5 and the adjustable resistor 6 are connected in series, and the currents of the two are the same. When the voltage remains unchanged, the resistance of the adjustable resistor 6 increases, and the current in its circuit will decrease, and the current in the magnetic force regulating coil 5 will also decrease; when the resistance of the adjustable resistor 6 decreases, the current in its circuit will increase, and the current in the magnetic force regulating coil 5 will also increase. Therefore, by adjusting the resistance of the adjustable resistor 6, the current in the magnetic force regulating coil 5 can be conveniently adjusted, thereby realizing the control of the magnetic force.

[0046] Of course, in other embodiments, the adjustable resistor 6 may not be provided, and the magnitude of the magnetic force may be controlled by directly controlling the change in the magnitude of the current in the magnetic force regulating coil 5 .

[0047] See also Figure 2 and Figure 5 As shown, in some optional embodiments, the housing 1 may be provided with a feel adjustment knob 12 (wherein the feel adjustment knob 12 may be a small knob arranged around the large shift knob 11, which may support a downward pressing action and a rotation action around its axis). When the feel adjustment knob 12 is pressed, the feel adjustment knob 12 triggers a control signal for controlling the direction of the current in the magnetic force adjustment coil 5. The switch of the feel adjustment knob 12 is monostable, and a level may be triggered by pressing downward. After receiving the level signal, the vehicle MCU may reverse the positive and negative poles of the energized coil, thereby switching the direction of the current in the magnetic force adjustment coil 5, and further adjusting the moving direction of the contact member 3, so that the contact member 3 may move toward the direction close to the contact curve 21 with the largest curvature, or may move toward the direction close to the contact curve 21 with the smallest curvature.

[0048] Furthermore, by rotating the feel adjustment knob 12, the feel adjustable mode can be turned on or off. By adjusting the rotation angle of the feel adjustment knob 12, the current of the energized coil can be changed (i.e., the resistance value of the adjustable resistor 6 is adjusted), and the magnetic field strength can be adjusted.

[0049] See also Figure 2 As shown, in some embodiments, a slider 7 can be installed in the shell 1, and first springs 8 can be connected to opposite sides of the slider 7, respectively, wherein one first spring 8 can be arranged on each side of the slider 7. Of course, multiple first springs 8 can also be arranged on each side, and the magnet 4 can be fixed to the slider 7, and the contact member 3 is installed on the slider 7. Since the magnet 4 is fixed on the slider 7, the attraction or repulsion force generated by the magnetic force adjustment coil 5 on the magnet 4 will also act on the slider 7, thereby driving the slider 7 to move, and the slider 7 can drive the contact member 3 to move together while moving, thereby realizing the movement of the contact member 3. In this embodiment, the movement of the contact member 3 is indirectly driven by driving the movement of the slider 7, so that the wear of the contact member 3 can be reduced, and the contact member 3 is connected by the slider 7 and the first spring 8, which can ensure that the contact member 3 can move more smoothly.

[0050] See also Figure 1 and Figure 2 As shown, in some optional embodiments, a slide groove 71 may be provided in the slider 7, the contact piece 3 may be inserted in the slide groove 71, and the contact piece 3 may move up and down in the slide groove 71, the contact piece 3 may at least partially protrude from the slide groove 71, so that the contact piece 3 can contact the curved block 2, and a second spring 9 may be provided between the bottom of the contact piece 3 and the inner wall of the slide groove 71, the second spring 9 may elastically support the contact piece 3, so that when the contact piece 3 moves along the contact curve 21, it can move up and down, and is in contact with the contact curve 21 at all times during the movement.

[0051] Furthermore, when the contact member 3 moves to the contact curve 21 with a smaller curvature, the gear shifting feel can be switched to a comfortable feel, and when the contact member 3 moves to the contact curve 21 with a relatively larger curvature, the gear shifting feel can be switched to a sporty feel.

[0052] See also Figure 5 As shown, in some embodiments, an atmosphere light may be provided at the feel adjustment knob 12, and the color of the atmosphere light is different when the contact member 3 switches to contact different contact curves 21. The comfort mode may be set to a green light, and the sports mode may be set to a red light.

[0053] In some optional embodiments, a memory mode may be optionally added to the knob electronic shifter, that is, the knob electronic shifter may also be provided with a memory module, and the memory module is used to automatically adjust the contact member 3 to a corresponding position according to a preset shift feel. That is, the next time the power is turned on, the contact member 3 may be automatically adjusted to a corresponding position according to the shift feel set in this round.

[0054] See also Figure 2 As shown, further, the knob electronic shifter can default to the closed state of the feel adjustment knob 12 when leaving the factory, and the shift feel at this time is determined by the position of the contact member 3, and in this embodiment, the position of the contact member 3 is determined by the parameters of the first spring 8 on both sides of the slider 7 (here defined as the first side and the second side) and the installation space of the housing 1. Among them, the first spring 8, the slider 7 and the contact member 3 are all installed in the installation space.

[0055] The position of the contact 3 can be locked by the following formula:

[0056] K1*(L1-L1')=K2*(L2-L2')

[0057] L1'+L2'+L3=L4

[0058] Among them, K1 is the stiffness of the first spring 8 on the first side of the slider 7, K2 is the stiffness of the first spring 8 on the second side of the slider 7, L1 is the free length of the first spring 8 on the first side of the slider 7, L2 is the free length of the first spring 8 on the second side of the slider 7, L1' is the length of the first spring 8 on the first side of the slider 7 after assembly, L2' is the length of the first spring 8 on the second side of the slider 7 after assembly, L3 is the thickness of the slider 7, and L4 is the length of the installation space. K1, L1, K2, L2, L3, and L4 are all known quantities, and L1' and L2' can be calculated to confirm the position of the contact 3.

[0059] In some embodiments, assuming that the vehicle is powered on and initialized by default to the comfortable shift feel mode, and the ambient light is lit green, the magnetic field generated by the magnetic force adjustment coil 5 repels the magnet 4, pushing the slider 7 to drive the contact 3 to move inside the housing 1, then the following formula is obtained:

[0060] K1*(L1-L1'+Δx)-F1=K2*(L2-L2'-Δx),

[0061] Among them, F1 is the repulsive force generated by the magnetic force regulating coil 5 and the magnet 4, and the magnet 4 can be coated in the slider 7. Through the change in the displacement of Δx, the contact member 3 can be adjusted to move Δx inside the housing 1, the corresponding rotation radius of the internal contact curve 21 is reduced, the difference between the peak and the trough is also reduced, and the curve shape transition is smoother, that is, the resistance torque of the knob is reduced, which is correspondingly reflected in the reduction of the operating torque of the shift knob 11.

[0062] Further, by pressing the feel adjustment knob 12, the sport shift feel mode can be switched, and the ambient light lights up red at the same time. The magnetic field generated by the magnetic force adjustment coil 5 attracts the magnet 4, pushing the slider 7 to drive the contact 3 to move outside the housing 1, and the following formula is obtained:

[0063] K1*(L1-L1'-Δx)+F2=K2*(L2-L2'+Δx)

[0064] Among them, F2 is the attraction generated by the magnetic force regulating coil 5 and the magnet 4. Through the change in the displacement Δx, the contact member 3 can be adjusted to move Δx outside the shell 1, the rotation radius corresponding to the internal contact curve 21 increases, the difference between the peaks and troughs also increases, and the curve shape transition becomes steeper, that is, the resistance torque of the knob becomes larger, which is correspondingly reflected in the increase in the operating force of the shift knob 11.

[0065] In some optional embodiments, in order to weaken the influence of the magnetic field on the spring and the Hall sensor, it is recommended that the first spring 8 and the second spring 9 be non-magnetic springs, and the position detection of the shift knob 11 be optical position detection. If a Hall sensor is used, a magnetic resistance structure can be used to isolate the mutual influence between the magnetic field of the magnetic force adjustment coil 5 and the gear detection magnetic field.

[0066] The design process of the knob electronic shifter provided by the embodiment of the present invention may include the following steps:

[0067] 1. The formulation of the basic shift feel target includes: designing the curve shape of the surface block 2 corresponding to the initial position of the contact member 3, selecting the first spring 8, selecting the radius of the contact member 3, and selecting the parameters of the second spring 9.

[0068] 2. Make a quick sample for verification to determine whether the gear shift feel is acceptable. If so, proceed to the next step; otherwise, return to the first step and set the basic gear shift feel target.

[0069] 3. The gear shift feel target setting after the magnetic force regulating coil 5 intervenes includes: the design of the curvature of the variable curvature surface 22 of the curved surface block 2, the design of the magnetic field strength of the magnet 4, the design of the parameters of the magnetic force regulating coil 5, and the design of the resistance value variation range corresponding to the adjustable resistor 6.

[0070] 4. Make a quick sample for verification to determine whether the shift feel of the knob electronic shifter within the full adjustment range is acceptable. If so, lock all technical parameters and open the mold; otherwise, return to the previous step to set the shift feel target after the force adjustment coil is involved.

[0071] Once the knob electronic shifter structure provided in the embodiment of the present invention is locked, the shift force feel is not locked, and the feel can be infinitely adjustable; market customers can adjust the shift feel mode that suits them according to their preferences; the curved block 2 is a mold part, and there is no need to re-open the mold according to the needs of different people, resulting in repeated investment in development costs; and the need for too many springs can be avoided to achieve different shift feels and increase the difficulty of product management.

[0072] An embodiment of the present invention further provides a vehicle, which may include a vehicle body, and the above-mentioned knob electronic shifter installed on the vehicle body.

[0073] The present invention adopts a specially made curved block 2 with a continuously changing curvature, and the position of the contact member 3 is also not fixed, and can be easily adjusted according to customer needs through a small adjustment knob arranged around the shift knob 11. By combining the curved block 2 with a continuously changing curvature and the contact member 3 with a changing position, the shift feel can be infinitely adjusted.
