In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0040] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings:

[0041] refer to Figures 1 to 3 According to the shifting device of the first aspect of the present application, the shifting device includes a housing 100, a first pin shaft 110 and an operating module 200. The housing 100 is provided with a limit portion 120 and a through hole 130. The limit portion 120 is provided with a guide slope 121. The operating module 200 is rotatably connected to the housing 100 through the first pin shaft 110. The operating module 200 is used to be connected to a speed change device. The speed change device can be a transmission or an electric motor for transmitting power to the wheels of the vehicle. The first pin shaft 110 is configured to abut against the guide slope 121 when penetrating the through hole 130 along the first direction, so that the guide slope 121 moves along the radial direction of the through hole 130, so as to prevent the guide slope 121 from hindering the first pin shaft 110 from moving along the first direction After penetrating into the through hole 130, the guide bevel 121 is configured to rebound and reset after losing the resistance with the first pin shaft 110, that is, rebound and reset to a position that can limit the first pin shaft 110 from being withdrawn from the through hole 130 along the second direction. The first direction is opposite to the second direction. The setting of the guide bevel 121 on the limiting portion 120 facilitates the first pin shaft 110 to penetrate into the through hole 130 to rotationally connect the shell 100 and the operating module 200, and it can also automatically rebound and reset to limit the first pin shaft 110 from being withdrawn from the through hole 130 along the second direction, effectively ensuring the stability of the connection between the shell 100 and the operating module 200, and can also facilitate the disassembly and assembly of the first pin shaft 110 by resisting the limiting portion 120, which is beneficial to the disassembly and assembly of the shift device.

[0042] Specifically, along the first direction, the guide bevel 121 is inclined toward the center of the through hole 130 to provide guidance for the first pin 110 to penetrate into the through hole 130. The guide bevel 121 can move radially along the through hole 130 under the support of the first pin 110 to avoid the first pin 110 from penetrating into the through hole 130. After losing the support of the first pin 110, the guide bevel 121 can automatically reset along the radial direction of the through hole 130, that is, reset to the path of the first pin 110 withdrawing from the through hole 130 along the second direction to limit the first pin 110 from withdrawing from the through hole 130 along the second direction. The guide bevel 121 can move radially along the through hole 130 under the support of the first pin 110. It should be understood that the guide bevel 121 itself can produce elastic deformation, or the guide bevel 121 is connected to the housing 100 through an elastic structure to ensure that the guide bevel 121 moves radially along the through hole 130. 0, so that the first pin shaft 110 can penetrate into the through hole 130 along the first direction or be pulled out of the through hole 130 along the second direction. When being pulled out of the through hole 130 along the second direction, the guide bevel 121 limits the movement of the first pin shaft 110 along the second direction. Therefore, it is necessary to use external force to resist the guide bevel 121 so that the guide bevel 121 moves along the radial direction of the through hole 130 relative to the through hole 130 to offset and avoid the first pin shaft 110. Compared with axial positioning structures such as spring retaining rings and positioning pins, no additional tools are required for disassembly, which is convenient and quick, and convenient for disassembly and maintenance of the shifting device.

[0043] It should be noted that a joystick 240 is provided on the operating module 200, and the axial force borne by the first pin shaft 110 mainly comes from the user turning the joystick 240. Therefore, the force borne by the guide slope 121 from the first pin shaft 110 is relatively small, and the guide slope 121 can also easily realize the limiting function when it has elastic deformation ability.

[0044] refer to Figure 1 to Figure 2 In some embodiments, the guide slope 121 can also be a concave surface adapted to the shape of the first pin shaft 110. The concave surface cooperates with the first pin shaft 110 to effectively avoid the first pin shaft 110 from slipping and disengaging from the abutment with the guide slope 121 when it abuts against the guide slope 121. The setting of the concave surface helps to improve the slippage between the first pin shaft 110 and the guide slope 121, thereby improving the assembly efficiency of the shifting device.

[0045] refer to Figures 1 to 3In other embodiments, the limiting portion 120 is slidably connected to the shell 100 through an elastic structure. The elastic structure can be an elastic structure such as a spring. Compared with the limiting portion 120 directly provided as an integral part on the shell 100, the limiting portion 120 is slidably connected to the shell 100 by providing an elastic structure, and it is more labor-saving to abut against the guide inclined surface 121, and a better rebound effect can be obtained. If it is an integrated structure, the guide inclined surface 121 is abutted multiple times and its rebound performance is easily destroyed. The elastic structure is beneficial to extending the service life of the limiting portion 120.

[0046] refer to Figures 1 to 3 In some embodiments, along the first direction, a bearing plane 140 is further provided at one end of the limiting portion 120 close to the through hole 130. The bearing plane 140 is configured to drive the guiding inclined surface 121 to move along the radial direction of the through hole 130 to avoid the first pin shaft 110. It should be noted that when disassembling the first pin shaft 110, the guiding inclined surface 121 needs to be moved, and directly abutting the guiding inclined surface 121 to drive it to move along the axial direction of the through hole 130 is prone to sliding. The bearing plane 140 is convenient for abutment and maintains the stability of the abutment. By abutting the bearing plane 140, the guiding inclined surface 121 can be driven to avoid the first pin shaft 110 from leaving the through hole 130 along the second direction, which is convenient for the disassembly of the first pin shaft 110.

[0047] refer to Figures 1 to 3 In some embodiments, a guide groove 150 extending along the first direction is further provided on the shell 100. Along the first direction, the guide slope 121 is located between the guide groove 150 and the through hole 130, and the guide groove 150 is butted with one end of the guide slope 121. When the first pin shaft 110 penetrates the through hole 130 along the first direction, the first pin shaft 110 is first placed in the guide groove 150. Since the guide groove 150 is butted with the guide slope 121, it is convenient for the first pin shaft 110 to stably abut against the guide slope 121, thereby ensuring the guiding function of the guide slope 121 and helping to further improve the smoothness of the installation of the first pin shaft 110.

[0048] refer to Figures 1 to 3 In some embodiments, a protrusion 111 is provided on the first pin shaft 110, and the protrusion 111 protrudes outward from the surface of the first pin shaft 110. Along the first direction, one side of the protrusion 111 abuts against the housing 100 to limit the movement of the first pin shaft 110 relative to the housing 100 along the first direction. It should be noted that along the second direction, the other side of the protrusion 111 abuts against the limiting portion 120, and the limiting portion 120 is used to limit the movement of the first pin shaft 110 relative to the housing 100 along the second direction. Therefore, under the joint action of the protrusion 111, the housing 100 and the limiting portion 120, the axial movement of the first pin shaft 110 relative to the housing 100 is completely restricted, that is, the first pin shaft 110 can only rotate relative to the housing 100, which is beneficial to ensuring the stability of the gear shifting of the gear shifting device.

[0049] refer to Figures 1 to 5 In some embodiments, the shift device further includes a control module 300 connected to the housing 100, and the operating module 200 further includes an operating body 210 and a sensing part 220. Along the first direction, the control module 300 is fixedly connected to the housing 100, and the sensing part 220 is located on a side of the operating body 210 close to the control module 300. The operating body 210 is rotatably connected to the housing 100 through the first pin shaft 110. The control module 300 is used for communication connection with the speed shift device. The sensing part 220 is configured to move relative to the control module 300 as the operating body 210 rotates relative to the housing 100 to change the output signal of the control module 300, that is, the sensing part 220 corresponds to different positions of the control module 300, so that the control module 300 can output different signals, thereby adjusting the output speed and / or torque of the speed shift device. Compared with realizing gear switching through a transmission rod, it is beneficial to reduce the structural wear caused by gear switching, and its gear adjustment is also more accurate and sensitive.

[0050] Specifically, a joystick 240 for the user to hold is provided on the control body 210, and a gear slot corresponding to different gears is also provided on the shell 100. The joystick 240 is inserted into the gear slot. The user can move the joystick 240 along the gear slot by toggling the joystick 240, that is, the control body 210 rotates relative to the shell 100, thereby driving the sensing part 220 to move relative to the control module 300. The sensing part 220 corresponds to different positions of the control module 300, and can enable the control module 300 to output different signals to achieve gear switching.

[0051] It should be noted that the sensing part 220 can be a magnet, and a Hall element can be provided on the control module 300. The sensing part 220 and the control module 300 are arranged adjacent to each other. The Hall element can sense the magnetic field generated by the magnet. By changing the relative position of the sensing part 220 and the control module 300, the magnetic field strength and / or direction applied by the sensing part 220 to the Hall element can be changed. The Hall element can sense the change of the magnetic field and convert the change of the magnetic field into an electrical signal output, thereby realizing the change of the output signal. The Hall element outputs an electrical signal by sensing the magnetic field and the change, which can be realized by those skilled in the art according to the function of the existing control module, and its control principle and control method are not described in detail here.

[0052] refer to Figures 1 to 5In some embodiments, the first pin shaft 110 is extended along the first direction, and the operating body 210 is rotatably connected to the housing 100 through the first pin shaft 110, and the movement of the first pin shaft 110 along the first direction or along the second direction is jointly limited by the housing 100, the limiting portion 120 and the protruding portion 111, so that when the operating body 210 rotates around the first pin shaft 110, the position of the operating body 210 relative to the housing 100 along the first direction remains unchanged. Along the first direction, the sensing portion 220 is arranged between the operating body 210 and the control module 300, and the sensing portion 220 is connected to the operating body 210, so that along the first direction, the sensing portion 220 and the control module 300 always maintain a fixed interval, that is, the sensing portion 220 is configured to move in a plane parallel to the control module 300, which is beneficial to ensure the stability of the magnetic field applied by the sensing portion 220 to the control module 300 and enhance the reliability of the gear switching of the shifting device.

[0053] refer to Figure 6 and Figure 7 In some embodiments, the operating module 200 includes a second pin shaft 230, a first operating member 211 and a second operating member 212. The first operating member 211 is rotatably connected to the shell 100 through the first pin shaft 110. The first operating member 211 is also rotatably connected to the second operating member 212 through the second pin shaft 230. The extension direction of the second pin shaft 230 is perpendicular to the extension direction of the first pin shaft 110. The second operating member 212 is provided with an operating rod 240. The second operating member 212 rotates around the second pin shaft 230 relative to the first operating member 211. The first operating member 211 drives the second operating member 212 to rotate around the first pin shaft 110 together with the shell 100, so that the operating rod 240 includes the action of rotating around the first pin shaft 110 and rotating around the second pin shaft 230, which is beneficial to realize more gear combinations and improve the flexibility of shifting of the shifting device.

[0054] Specifically, the sensing part 220 is connected to the first operating member 211 and the second operating member 212 at the same time. The sensing part 220 is also connected to a planar structure parallel to the control module 300 and can slide on the planar structure. Driven by the first operating member 211 or the second operating member 212, the sensing part 220 always maintains the same interval with the control module 300, thereby ensuring that the distance between the sensing part 220 and the control module 300 remains unchanged along the first direction, which makes it easy for the control module 300 to sense the magnetic field generated by the sensing part 220, which is beneficial to accurately control the switching of gears.

[0055] It should be noted that the extension direction of the second pin shaft 230 is perpendicular to the extension direction of the first pin shaft 110, the extension direction of the first pin shaft is perpendicular to the plane where the control module 300 is located, and the extension direction of the second pin shaft 230 is parallel to the plane where the control module 300 is located. Therefore, if the sensing part 220 is to be ensured to slide in a plane parallel to the control module 300 when the second operating member 212 rotates around the second pin shaft 230, it is necessary that the connection part between the second operating member 212 and the sensing part 220 has a certain degree of elasticity, and the second operating member 212 can rotate relative to the sensing part 220, or the second operating member 212 is hinged to the sensing part 220 to adapt to the change in the distance between the sensing part 220 and the second pin shaft 230 when the sensing part 220 slides in a plane parallel to the control module 300.

[0056] refer to Figures 1 to 4 In some embodiments, the second operating member 212 is connected to the sensing part 220, and the first operating member is slidably connected to the sensing part 220. The sensing part 220 is configured to slide relative to the first operating member 211 along a third direction as the second operating member 212 rotates relative to the first operating member 211. The third direction is parallel to the plane where the control module 300 is located. The second operating member 212 is connected to the first operating member 211 through the second pin shaft 230. The connection between the second operating member 212 and the sensing part 220 ensures that the second operating member 212 rotates relative to the sensing part 220 and also includes relative movement along the extension direction of the first pin shaft 110. Therefore, when the second operating member 212 rotates around the second pin shaft 230, the sensing part 220 can slide along the third direction relative to the first operating member 211, so as to avoid interference between the second operating member 212 driving the sensing part 220 to move and the sensing part 220 sliding along the third direction relative to the first operating member 211, wherein the third direction, the extension direction of the first pin shaft 110 and the extension direction of the second pin shaft 230 are perpendicular to each other, and the extension direction of the first pin shaft 110 is perpendicular to the plane where the control module 300 is located. Thus, the gear switching is achieved with the interval between the sensing part 220 and the control module 300 unchanged, which is beneficial to improving the sensitivity of the gear switching.

[0057] It should be noted that the second operating member 212 and the sensing part 220 can be connected by a ball pin. In addition to the relative rotation of the sensing part 220 and the second operating member 212, the ball pin is provided with a accommodating cavity extending along the first pin shaft 110, so that the ball head part on the second operating member 212 can also move relative to the sensing part 220 along the extension direction of the first pin shaft 110 in the accommodating cavity, thereby increasing the flexibility of the connection to adapt to the characteristic that the sensing part 220 always moves along the third direction in a plane parallel to the operating module 200 under the drive of the first operating member 211 and the second operating member 212, thereby making the gear switching smoother and more sensitive.

[0058] refer to Figure 6 and Figure 7In some embodiments, either the shell 100 or the operating module 200 is provided with at least two limit grooves 170, and the other is slidably connected with a sliding portion 180. The sliding portion 180 is configured to be inserted into any limit groove 170 as the operating module 200 rotates relative to the shell 100. The cooperation between the sliding portion 180 and the limit groove 170 facilitates the user to determine whether the gear is switched successfully, which is beneficial to providing the user with a gear switching experience.

[0059] refer to Figure 6 and Figure 7 In some embodiments, the operating module 200 includes a first operating member 211 and a second operating member 212, the first operating member 211 is provided with at least two first limiting grooves 2111, and the second operating member 212 is also slidably connected with a first sliding portion 2121, and the first sliding portion 2121 is configured to be able to be inserted into any first limiting groove 2111 as the second operating member 212 rotates relative to the first operating member 211, that is, when the second operating member 212 rotates relative to the first operating member 211 around the second pin shaft 230, the first sliding portion 2121 resists the first operating member 211 and slides relative to the second operating member 212 to be inserted into the first limiting groove 2111, and each first limiting groove 2111 corresponds to one of the gears, which helps to give the user better gear shifting feedback and enhance the user's gear shifting experience.

[0060] It should be noted that the first sliding portion 2121 can be slidably connected to the second operating member 212 through a spring. The first sliding portion 2121 resists the first operating member 211 while being slidably connected to the second operating member 212. When the first sliding portion 2121 is inserted into the first limiting groove 2111, a certain amount of force is required to pry it out of the first limiting groove 2111. A curved surface for transition is provided between adjacent first limiting grooves 2111. The first sliding portion 2121 resists against the transition curved surface for smoother prying, thereby achieving smooth prying during gear switching and better feedback after successful gear switching, that is, the change from a smaller prying force to a larger prying force can be regarded as a successful gear switching. At the same time, the insertion of the first sliding portion 2121 into the first limiting groove 2111 can also give the user better feedback, which is beneficial to improving the user's gear switching experience.

[0061] refer to Figure 6 and Figure 7In other embodiments, the operating body 210 includes a first operating member 211 and a second operating member 212, the first operating member 211 is provided with at least two first limiting grooves 2111, the shell 100 is provided with at least two second limiting grooves 160, the second operating member 212 is slidably connected with a first sliding portion 2121, the first operating member 211 is connected with a second sliding portion 2112, the second operating member 212 rotates around the second pin shaft 230 relative to the first operating member 211, and the first operating member 211 rotates around the first pin shaft 110 relative to the shell 100. When the second operating member 212 rotates relative to the first operating member 211, the first sliding portion 2121 also slides relative to the second operating member 212 to be inserted into any first limiting groove 2111 to achieve gear switching. When the first operating member 211 rotates relative to the shell 100, the second sliding portion 2112 also slides relative to the first operating member 211 to be inserted into any second limiting groove 160, which is beneficial to making the gear grading more refined and increasing the flexibility of gear switching. The cooperation between the first sliding portion 2121 and the first limiting groove 2111, as well as the cooperation between the second sliding portion 2112 and the second limiting groove 160, makes it easy to determine whether the gear switching of the gear shifting device is successful, thereby improving the user's gear switching experience.

[0062] Among them, the extension direction of the first pin shaft 110 is perpendicular to the extension direction of the second pin shaft 230, a gear slot is provided on the shell 100, and an operating rod 240 is provided on the second operating member 212. The operating rod 240 is inserted into the gear slot. The user moves the operating rod 240 in the gear slot, and cooperates with the first sliding part 2121 and the first limiting slot 2111, as well as the second sliding part 2112 and the second limiting slot 160, so as to achieve smooth and obvious gear switching.

[0063] It should be noted that when the first operating member 211 rotates around the first pin shaft 110 relative to the shell 100, it also drives the second operating member 212 to rotate around the first pin shaft 110 relative to the shell 100. When the first sliding portion 2121 disengages from the first limiting groove 2111, the user will feel a greater resistance. When the first sliding portion 2121 slides outside the first limiting groove 2111, the resistance is smaller. Therefore, the user can determine whether the operating lever 240 is moved into place based on the smoothness of the movement. Similarly, the second sliding portion 2112 is placed in the second limiting groove 160 and encounters a greater resistance. The second sliding portion 2112 is placed outside the second limiting groove 160 and encounters a smaller resistance. Therefore, the accuracy of gear switching can be effectively improved.
