Conventional lever type and dial type electronic shifter usually have five operating positions, and the five operating positions are R position, reverse gear side neutral (Nr) position, middle (Null) position, drive gear side neutral (Nd) position and D position respectively. Driver realizes gear shifting by rotating gear shifting dial or gear shifting lever from Null position to D position, Nd position, R position or Nr position. Gear shifting dial can return to Null position from D position, Nd position, R position or Nr position after operating force is removed. However, gear shifting mode of such electronic shifter is only rotation, and gear shifting form is single, and driver is difficult to distinguish different gear shifting operations. Especially, when driving gear shifts to N gear, it is easy to misoperate and gear shift to R gear or D gear.

[0035] Reference will now be made in detail to various embodiments of the present application, examples of which are illustrated in the accompanying drawings and described below. While the present application will be described in conjunction with the exemplary embodiments, it should be understood that the present application is not limited to these exemplary embodiments. On the contrary, the present application is intended to cover all alternatives, modifications, equivalents and other embodiments that can be included within the spirit and scope of the present application as defined by the appended claims.

[0036] As shown in Figures 1 to 3e The gear shifting device 10 of the vehicle according to the present application includes a housing 100, a first gear shifting member 200, a first holding assembly 300, a second gear shifting member 400, a second holding assembly 500, and a detection module 600.

[0037] The housing 100 can be mounted in the interior of the vehicle, or integrated as a whole structure with other components in the vehicle (components near the gear shifting device 10), and the housing 100 has a receiving cavity to mount the first gear shifting member 200, the first holding assembly 300, the second gear shifting member 400, the second holding assembly 500, and the detection module 600.

[0038] The first holding assembly 300 and the second holding assembly 500 are both mounted in the receiving cavity of the housing 100, wherein the first holding assembly 300 is used to hold the first gear shifting member 200, and the second holding assembly 500 is used to hold the second gear shifting member 400. Through the support of the first holding assembly 300 and the second holding assembly 500, the first gear shifting member 200 and the second gear shifting member 400 can rotate and move relative to the housing 100, respectively.

[0039] The driver applies an operating force to the first shift member 200 or the second shift member 400, thereby controlling the first shift member 200 or the second shift member 400 to move (i.e., to move or rotate) relative to the housing 100. The detection module 600 detects the motion signal and sends a gear position signal corresponding to the motion signal to the vehicle control system, thereby controlling the vehicle to switch driving modes or gear positions.

[0040] like Figures 4 to 5b As shown, in some exemplary embodiments, the rotation of the first shifter 200 relative to the housing 100 is configured to switch the vehicle's driving mode, allowing the vehicle to switch between driving modes such as Normal Mode, Eco Mode, and Sport Mode. The vehicle's switchable driving modes are arranged in sequence. Each time the driver rotates the first shifter 200 relative to the housing 100, the vehicle switches to the next driving mode in the sequence, and the switching cycle continues in the arranged order (regardless of the rotation direction, the vehicle switches to the next driving mode in the arranged order). For example, when the vehicle is in Normal Mode, the driver rotates the first shifter 200 relative to the housing 100. The detection module 600 receives an action signal indicating the rotation of the first shifter 200 and then controls the vehicle to switch to Eco Mode. When the vehicle is in Eco Mode, the driver rotates the first shifter 200 relative to the housing 100 once. The detection module 600 receives a signal indicating the rotation of the first shifter 200 and then controls the vehicle to switch to Sport Mode. When the vehicle is in Sport mode, the driver rotates the first shift member 200 relative to the housing 100 once. The detection module 600 receives the rotation signal of the first shift member 200 and then controls the vehicle to switch to Normal mode. Each subsequent rotation of the first shift member switches the vehicle to the next driving mode in the aforementioned order.

[0041] Alternatively, the forward rotation of the first shift member 200 may be configured to switch to the previous driving mode, and the backward rotation of the second shift member 200 may be configured to switch to the next driving mode, so that the driver can quickly switch to the desired driving mode.

[0042] like Figures 6 to 6a As shown, in some exemplary embodiments, the movement of the first shift member 200 relative to the housing 100 is configured to shift the vehicle to the P gear. When the driver controls the first shift member 200 to move, the detection module 600 receives an action signal indicating the movement of the first shift member 200, thereby shifting the vehicle to the P gear.

[0043] like Figures 7 to 8b As shown, in some exemplary embodiments, the rotation of the second shift member 400 relative to the housing 100 is configured to shift to the D gear and the R gear.Figures 7 to 7b As shown, when the driver controls the second shift member 400 to rotate forward relative to the housing 100, the detection module 600 will receive a corresponding action signal, thereby controlling the vehicle to switch to the D gear. Figures 8 to 8b As shown, when the driver controls the second shift member 400 to rotate backward relative to the housing 100, the detection module 600 will also receive a corresponding action signal, thereby controlling the vehicle to switch to the R gear.

[0044] like Figures 9 to 9a As shown, in some exemplary embodiments, the movement of the second shift member 400 relative to the housing 100 is configured to shift the vehicle to the N gear. When the driver controls the second shift member 400 to move relative to the housing 100, the detection module 600 receives an action signal indicating the movement of the second shift member 400, thereby controlling the vehicle to shift to the N gear.

[0045] like Figures 2 to 3a As shown, the first shift member 200 is held on the left side of the housing 100 (i.e., the first side of the housing 100) and supported by the first holding assembly 300. The first shift member 200 can rotate relative to the housing 100 around the axis X (the axis X extends in the left-right direction) and move relative to the housing 100 to the right side of the housing 100 (i.e., the second side of the housing 100) (as shown in FIG. Figures 5 to 6 A portion of the first shift member 200 is located in the accommodating chamber, and another portion of the first shift member 200 is exposed outside the accommodating chamber through the chamber opening 114. In addition, the first shift member 200 forms an operating portion 210 at the left end portion (i.e., the first end portion of the first shift member 200).

[0046] The driver can control the rotation or movement of the first shift member 200 relative to the housing 100 by applying an operating force to the portion of the operating portion 210 exposed from the accommodating chamber. By pressing and holding the operating portion 210 of the first shift member 200 and pushing it forward or backward, the driver can control the rotation of the first shift member 200 relative to the housing 100, thereby switching the vehicle's driving mode. By pressing and holding the operating portion 210 of the first shift member 200 and applying a rightward operating force, the driver can push the first shift member 200 to the right relative to the housing 100, thereby switching the vehicle's gear position to P.

[0047] Specifically, a recess 220 is formed at the left end of the first shifter 200, with the operating portion 210 located to the left of the recess 220. Furthermore, to enhance the driver's grip stability when operating the first shifter 200 and prevent slippage and operational errors, the operating portion 210 may also be designed with anti-slip patterns or raised structures. This ensures precise operation when switching driving modes or selecting P gear, thereby enhancing the operability and safety of the first shifter 200.

[0048] As shown in FIG. 1, the first shift member 200 is retained in the housing 100 and is supported by a first retaining assembly 300. The first shift member 200 is capable of rotating about the axis X relative to the housing 100 and moving toward the right side of the housing 100 (as shown in FIG. 1). That is, the first shift member 200 is capable of rotating about the same rotation axis and moving toward the same direction as the second shift member 400. Figures 2 to 3a As shown in FIG. 1, the second shift member 400 is retained in the housing 100, located at the right end of the first shift member 200 (i.e., the second end of the first shift member 200) and supported by a second retaining assembly 500. The second shift member 400 is also capable of rotating about the axis X relative to the housing 100 and moving toward the right side of the housing 100 (as shown in FIG. 1). That is, the second shift member 400 and the first shift member 200 are capable of rotating about the same rotation axis and moving toward the same direction. Figures 9 to 9a As shown in FIG. 1, the second shift member 400 is retained in the housing 100, located at the right end of the first shift member 200 (i.e., the second end of the first shift member 200) and supported by a second retaining assembly 500. The second shift member 400 is also capable of rotating about the axis X relative to the housing 100 and moving toward the right side of the housing 100 (as shown in FIG. 1). That is, the second shift member 400 and the first shift member 200 are capable of rotating about the same rotation axis and moving toward the same direction.

[0049] The second shift member 400 is located in the accommodating chamber and has a tab 410 protruding out of the accommodating chamber at the top thereof. The driver can control the rotation or movement of the second shift member 400 by applying an operating force to the tab 410. When the driver applies a forward operating force to the tab 410, the tab 410 tilts forward and the second shift member 400 rotates forward relative to the housing 100, thereby switching the gear of the vehicle to D. Similarly, when the driver needs to switch the gear of the vehicle to R, the driver can apply a backward operating force to the tab 410, in which case the tab 410 tilts backward and the second shift member 400 rotates backward relative to the housing 100, thereby switching the gear of the vehicle to R. When the driver needs to switch the vehicle to N, the driver applies a rightward operating force to the tab 410, in which case the second shift member 400 as a whole moves rightward relative to the housing 100, and then the vehicle is switched to N.

[0050] It is worth mentioning that the tab 410 is a plate-like structure, and the driver can control the vehicle to switch to D by applying a forward operating force to the rear side of the tab 410, control the vehicle to switch to R by applying a backward operating force to the front side of the tab 410, and control the vehicle to switch to N by applying a rightward operating force to the left side of the tab 410. In this way, different parts of the tab 410 are used to apply operating forces in different directions, thereby avoiding the occurrence of misoperation and switching to the wrong gear (i.e., the gear different from the gear intended by the driver).

[0051] As shown in FIG. 1, the second shift member 400 is retained in the housing 100, located at the right end of the first shift member 200 (i.e., the second end of the first shift member 200) and supported by a second retaining assembly 500. The second shift member 400 is also capable of rotating about the axis X relative to the housing 100 and moving toward the right side of the housing 100 (as shown in FIG. 1). That is, the second shift member 400 and the first shift member 200 are capable of rotating about the same rotation axis and moving toward the same direction. Figures 1 to 3aAs shown, the housing 100 comprises an upper housing 110 and a lower housing 120, which can be buckled to form a containing chamber. The side wall 111 of the upper housing 110 is formed with a first connecting part, and the side wall 111 of the lower housing 120 is formed with a second connecting part. When the upper housing 110 is buckled to the lower housing 120, the first connecting part can be connected with the second connecting part, thereby constituting the complete housing 100. For example, a clamping groove 112 can be arranged on the side wall 111 of the upper housing 110, and a clamping block 122 corresponding to the clamping groove 112 can be arranged on the side wall 111 of the lower housing 120. When the upper housing 110 and the lower housing 120 constitute the complete housing 100, the clamping block 122 can be clamped into the clamping groove 112. In particular, a deformation groove can be arranged on both sides of the clamping groove 112, so that when the clamping block 122 is clamped into the clamping groove 112, the clamping block 122 and the clamping groove 112 can move in opposite directions to facilitate the connection of the clamping block 122 and the clamping groove 112, thereby facilitating the assembly of the housing 100.

[0052] As shown in Figures 3a to 3c , the top of the upper housing 110 is formed with a chamber opening 114. The top of the first shift member 200 (i.e., the other part of the first shift member 200 mentioned above) can be exposed outside the containing chamber by the chamber opening 114, so that the driver can exert an operating force on the first shift member 200. The tab 410 of the second shift member 400 can be exposed outside the containing chamber by the chamber opening 114, so that the driver can exert an operating force on the second shift member 400.

[0053] As shown in Figures 3a to 3b , the bottom of the lower housing 120 has a circuit opening 124, and the detection module 600 is installed at a position corresponding to the circuit opening 124 on the bottom of the lower housing 120, so that the circuit of the detection module 600 can extend out of the containing chamber through the circuit opening 124.

[0054] As shown in Figure 1 , Figure 3b , Figure 3c , Figure 10 As shown in , the first retaining assembly 300 comprises two first retaining members 310 and a plurality of first fixing pins 320, and the two first retaining members 310 are respectively installed on the side wall 111 of the lower housing 120 through the first fixing pins 320. The first shift member 200 is located between the two first retaining members 310 and is supported by the two first retaining members 310. Through the support of the two first retaining members 310, the first shift member 200 can rotate and move relative to the housing 100.

[0055] Further, the opposite sides (i.e. the front side and the rear side shown in the figure) of the side wall 111 of the lower housing 120 are each provided with a first fixing hole, and the two first retainers 310 are each provided with a first pin hole corresponding to the first fixing hole. The first end of the first fixing pin 320 is inserted into the first fixing hole, and the second end of the first fixing pin 320 is inserted into the first pin hole, so that the two first retainers 310 are respectively mounted to the front side and the rear side of the lower housing 120 by the first fixing pins 320. When the first shift member 200 is located between the two first retainers 310 distributed in front and back, the movement of the first shift member 200 in the front-back direction is limited by the two first retainers 310, so that the first retaining assembly 300 can support the first shift member 200 in the front-back direction.

[0056] The surface of each first retainer 310 contacting the first shift member 200 is formed as a first contact surface concave, and the first shift member 200 has a second contact surface corresponding to the first contact surface, which is cylindrical. When the first shift member 200 is arranged between the two first retainers 310, the second contact surface of the first shift member 200 is fitted to the first contact surfaces of the two first retainers 310, at this time, the lower sides of the two first contact surfaces can prevent the first shift member 200 from moving downward, and the upper sides of the two first contact surfaces can prevent the first shift member 200 from moving upward. That is, the first shift member 200 can be supported in the vertical direction (i.e. the up-down direction in the figure) by the first contact surfaces respectively formed by the two first retainers 310.

[0057] As can be seen from the above, the two first retainers 310 can support the first shift member 200 in the front-back direction and the up-down direction. At the same time, the two first retainers 310 are arranged to allow the first shift member 200 to move in the left-right direction, so that the first shift member 200 can move relative to the housing 100 in the left-right direction. In fact, the first contact surfaces of the two first retainers 310 each extend in the left-right direction and define a slide way extending in the left-right direction, so that when the first shift member 200 is mounted between the two first retainers 310, it can move in the left-right direction.

[0058] After the first retainers 310 and the first shift member 200 are mounted to the housing 100, the axis of the cylindrical surface can coincide with the axis X, so that the first shift member 200 can rotate between the two first retainers 310. Thus, the two first retainers 310 not only allow the first shift member 200 to move in the left-right direction, but also allow the first shift member 200 to rotate about the axis X extending in the left-right direction.

[0059] As Figures 10 to 11As shown, each first retaining member 310 is formed into a concave side to form a first rotation guide groove 311, and the first rotation guide groove 311 is located on the left side (ie, the first side) of the first retaining member 310. Figure 1 、 Figure 8 As shown, a first slider 240 is formed at the left end (i.e., the first end) of the first shift member 200, corresponding to the first rotation guide groove 311. The first slider 240 is located in the recess 220, i.e., a first slider 240 is provided on both the front and rear sides of the recess 220. The first rotation guide groove 311 allows the first slider 240 to slide within it. When the first slider 240 is located in the first rotation guide groove 311, the first shift member 200 can rotate between the two first retaining members 310. At the same time, as the first shift member 200 rotates, the first slider 240 is restrained by the first rotation guide groove 311, preventing it from moving leftward and rightward between the two first retaining members 310.

[0060] like Figure 11 As shown, the bottom of the first rotation guide groove 311 is formed as a first rotation guide plane 3111, and the center of the first rotation guide plane 3111 is recessed in the direction away from the first shifting member 200 to form a first turning portion 3111a. In other words, the first rotation guide plane 3111 is divided into two parts by the first turning portion 3111a, and both parts are flat.

[0061] like Figure 3b As shown, each first slider 240 includes a first slider body 241, a first hole 242, a first spring 243, and a first contact and expansion joint 244. The first slider body 241 is formed with the first hole 242, and the first spring 243 is disposed within the first hole 242. The first end of the first contact and expansion joint 244 is located within the first hole 242, and the second end of the first contact and expansion joint 244 is capable of close contact with the first rotation guide plane 3111. Specifically, one end of the first spring 243 abuts against the bottom of the first hole 242, while the other end supports the first end of the first contact and expansion joint 244, ensuring that the second end of the first contact and expansion joint 244 is in constant close contact with the first rotation guide plane 3111.

[0062] Under the action of the first spring 243 and the first abutting telescopic head 244, the first shift element 200 can be kept in the first stable position, which is the position that the first slider 240 corresponds to the first turning corner 3111a of the first turning guide plane 3111, i.e. the first abutting telescopic head 244 of the first slider 240 is in close contact with the first turning guide plane 3111 at the first turning corner 3111a. In other words, when the driver does not apply a forward or backward operating force to the first shift element 200, the first shift element 200 does not rotate, at this time, the first slider 240 corresponds to the first turning corner 3111a in the first turning guide groove 311, and the first shift element 200 is in the first stable position. When the driver applies a forward or backward operating force to the first shift element 200, the first shift element 200 rotates forward or backward around the axis X, and the driving mode of the vehicle is switched to another driving mode. In this process, the two first sliders 240 respectively slide in the first turning guide groove 311 from the first turning corner 3111a, wherein one first slider 240 slides upward and the other first slider 240 slides downward. At this time, the first abutting telescopic head 244 moves toward the bottom of the first hole 242, and at the same time the first spring 243 is compressed by the first abutting telescopic head 244. After the driver withdraws the operating force, the first spring 243 gradually expands and pushes the first abutting telescopic head 244 to move outwardly of the first hole 242 and exerts a pressure on the first turning guide plane 3111. In this process, the first abutting telescopic head 244 is subjected to a reaction force from the first turning guide plane 3111, which promotes the first shift element 200 to rotate and the direction of rotation is opposite to that of the first shift element 200 when the driver operates, until the first abutting telescopic head 244 moves to the first turning corner 3111a, i.e. the position that the first slider 240 corresponds to the first turning corner 3111a, at this time, the vehicle will be in the other driving mode.

[0063] As shown in Figures 10 to 11 each first retaining element 310 is formed with a moving guide groove 312 on the side of the concave surface, the left end (i.e. the first end) of the moving guide groove 312 is connected to the first turning guide groove 311, and the right end (i.e. the second end) of the moving guide groove 312 is located on the right side (i.e. the second side) of the first retaining element 310. In other words, the right side of the first turning guide groove 311 is also formed with the moving guide groove 312, the left end of the moving guide groove 312 is connected to the first turning guide groove 311, and the moving guide groove 312 extends rightward from the left end to form the second end, i.e. the moving guide groove 312 extends in the left-right direction.

[0064] The first end of the moving guide groove 312 corresponds to the first turning portion 3111a, so that when the first shift element 200 is in the first stable position, i.e. the first slider 240 on the first shift element 200 corresponds to the first turning portion 3111a, the first shift element 200 can move relative to the housing 100 in the left-right direction. In this process, the first slider 240 first moves to the right from the first turning portion 3111a into the moving guide groove 312, and then moves to the right in the moving guide groove 312.

[0065] In the process of switching the vehicle to P gear, the driver controls the first shift element 200 in the first stable position to move to the right, at this time, the first slider 240 moves to the right from the first turning guide groove 311 to the moving guide groove 312, and after moving a certain distance in the moving guide groove 312, the vehicle is switched to P gear (as shown in Figures 6 to 6a

[0066] As shown in Figure 11 , the moving guide groove 312 is also provided with a limiting portion 3121 located near the left end of the moving guide groove 312. When the first shift element 200 moves to the right relative to the housing 100, the first slider 240 slides to the right in the moving guide groove 312. When the first slider 240 slides a certain distance to the limiting portion 3121, the first shift element 200 will not be able to continue to move to the right, so that the limiting portion 3121 can limit the movement of the first shift element 200 to the second side of the housing 100. When the first shift element 200 moves to the right relative to the housing 100, the first slider 240 is located in the moving guide groove 312, and since the first slider 240 (at least the first abutting and telescopic head 244 of the first slider 240) is limited by the moving guide groove 312, the first shift element 200 cannot rotate relative to the housing 100.

[0067] As can be seen from the above, when the first shift element 200 rotates relative to the housing 100, the first retaining assembly 300 can limit the movement of the first shift element 200, and when the first shift element 200 moves relative to the housing 100, the first retaining assembly 300 can limit the rotation of the first shift element 200.

[0068] It is worth mentioning that, as shown in Figure 10 and Figure 11 , each first retaining piece 310 is also provided with an avoiding groove 313, and when the first retaining piece 310 is installed on the side wall 111 of the lower housing 120, the clamping block 122 on the lower housing 120 can be embedded in the avoiding groove 313.

[0069] As shown in Figure 3a , Figure 3c ​As shown, the right end of the first shift member 200 forms a first receiving chamber 250, and the top of the first shift member 200 forms a receiving groove 260 corresponding to the tab 410 of the second shift member 400, the receiving groove 260 being above the first receiving chamber 250. As shown in the figure, the first shift member 200 is provided with a first retaining assembly 300, and the second shift member 400 is provided with a second retaining assembly 500. Figures 6 to 6a As shown, when the first shift member 200 moves right relative to the housing 100, the first retaining assembly 300 restricts the rotation of the first shift member 200 relative to the housing 100, and the left end (i.e., the first end) of the second shift member 400 can be received in the first receiving chamber 250, and the tab 410 can be received in the receiving groove 260. Thus, the first shift member 200 restricts the forward and backward tilting of the tab 410 through the receiving groove 260, and further restricts the rotation of the second shift member 400. Therefore, when the first shift member 200 moves right to switch the vehicle to P gear, the second shift member 400 is locked by the first shift member 200 and cannot rotate relative to the housing 100, so it cannot be selected to switch to D gear or R gear.

[0070] And when the first shift member 200 moves right to the P gear position, if the driver does not apply a left operating force to it, the first shift member 200 will be stably in the P gear position. Thus, while switching to P gear through the first shift member 200, the second shift member 400 is locked by the first shift member 200, avoiding the misoperation of switching to D gear or R gear in the P gear state, ensuring the safety of the operation.

[0071] As shown in the figure, the second retaining assembly 500 includes two second retaining members 510, a plurality of second fixed pins 520, and an auxiliary retaining member 530. The two second retaining members 510 are respectively mounted to the side wall 111 of the lower housing 120 through the second fixed pins 520. The auxiliary retaining member 530 is located between the two second retaining members 510 and is supported by the two second retaining members 510, and through the support of the two second retaining members 510, the auxiliary retaining member 530 can move relative to the housing 100. Figure 1 Figure 12 As shown in the figure, the side wall 111 of the lower housing 120 is provided with a second fixed hole on each of the opposite sides (i.e., the front side and the rear side shown in the figure), and the two second retaining members 510 are provided with a second pin hole corresponding to the second fixed hole. The first end of the second fixed pin 520 is inserted into the second fixed hole, and the second end of the second fixed pin 520 is inserted into the second pin hole, so that the two second retaining members 510 are respectively mounted to the front side and the rear side of the lower housing 120 through the plurality of second fixed pins 520.

[0072] As shown in the figure, the side wall 111 of the lower housing 120 is provided with a second fixed hole on each of the opposite sides (i.e., the front side and the rear side shown in the figure), and the two second retaining members 510 are provided with a second pin hole corresponding to the second fixed hole. The first end of the second fixed pin 520 is inserted into the second fixed hole, and the second end of the second fixed pin 520 is inserted into the second pin hole, so that the two second retaining members 510 are respectively mounted to the front side and the rear side of the lower housing 120 through the plurality of second fixed pins 520. Figure 12 As shown in the figure, the side wall 111 of the lower housing 120 is provided with a second fixed hole on each of the opposite sides (i.e., the front side and the rear side shown in the figure), and the two second retaining members 510 are provided with a second pin hole corresponding to the second fixed hole. The first end of the second fixed pin 520 is inserted into the second fixed hole, and the second end of the second fixed pin 520 is inserted into the second pin hole, so that the two second retaining members 510 are respectively mounted to the front side and the rear side of the lower housing 120 through the plurality of second fixed pins 520.

[0073] ​The auxiliary retaining member 530 is located between two second retaining members 510 distributed in front and back, and the movement of the auxiliary retaining member 530 in the front and back direction is limited by the two second retaining members 510 respectively, so that the two second retaining members 510 can support the auxiliary retaining member 530 in the front and back direction.

[0074] The surface of each second retaining member 510 contacting the auxiliary retaining member 530 is formed as a concave surface, and the auxiliary retaining member 530 is formed as a convex surface corresponding to the concave surface, and the convex surface can be fitted to the concave surface. When the auxiliary retaining member 530 is arranged between the two second retaining members 510, the convex surfaces formed on the front and back sides of the auxiliary retaining member 530 are respectively fitted to the concave surfaces of the front and back second retaining members 510, at this time, the lower sides of the two concave surfaces can prevent the auxiliary retaining member 530 from moving downward, and the upper sides of the two concave surfaces can prevent the auxiliary retaining member 530 from moving upward, that is, the auxiliary retaining member 530 can be supported in the vertical direction (i.e., the up and down direction in the figure) by the concave surfaces formed by the two second retaining members 510.

[0075] As can be seen from the above, the two second retaining members 510 can support the auxiliary retaining member 530 in the front and back direction and the up and down direction. At the same time, the two second retaining members 510 are arranged to allow the auxiliary retaining member 530 to move in the left and right direction, so that the auxiliary retaining member 530 can move relative to the housing 100 in the left and right direction, in fact, the concave surfaces of the two second retaining members 510 both extend in the left and right direction and define a slide way extending in the left and right direction, so that when the auxiliary retaining member 530 is mounted between the two second retaining members 510, it can move in the left and right direction.

[0076] It should be noted that the auxiliary retaining member 530 can only move relative to the two second retaining members 510 in the left and right direction, and cannot rotate relative to the two second retaining members 510, that is, the auxiliary retaining member 530 cannot rotate relative to the housing 100. Therefore, the concave surface formed by the second retaining member 510 and the convex surface formed by the auxiliary retaining member 530 can be arranged as a non-cylindrical surface to avoid rotation of the auxiliary retaining member 530. Or the rotation of the auxiliary retaining member 530 relative to the second retaining member 510 can be limited by other means known to those skilled in the art, for example, as shown in Figure 12 , a protrusion 125 can be arranged on the lower housing 120, and the protrusion 125 is embedded in the auxiliary retaining member 530, so that the auxiliary retaining member 530 cannot rotate relative to the second retaining member 510.

[0077] As Figure 3a , Figure 13As shown, the left end (i.e., the first end) of the auxiliary retainer 530 forms a second receiving chamber 531, and the right end of the second shift member 400 is retained in the second receiving chamber 531. Furthermore, the second shift member 400 cannot move left-right relative to the auxiliary retainer 530; in other words, the right end of the second shift member 400 is constantly retained in the second receiving chamber 531. However, because the auxiliary retainer 530 can move left-right relative to the housing 100, the second shift member 400 can move left-right relative to the housing 100 synchronously with the auxiliary retainer 530.

[0078] like Figure 3a As shown, the right end portion (i.e., the second end portion) of the auxiliary retaining member 530 has a moving gap Y, and the moving gap Y can provide a certain space for the auxiliary retaining member 530 to move to the right. Therefore, when the driver operates the second shift member 400 to switch to the N gear, the second shift member 400 can push the auxiliary retaining member 530 to move to the right synchronously, thereby switching the gear position of the vehicle to the N gear (as shown in FIG. Figure 9a shown).

[0079] As shown in 3a, the auxiliary retaining member 530 has a stop portion 533 at the bottom, and the lower shell 120 has a protrusion 125 corresponding to the stop portion 533. The protrusion 125 is formed with a third hole 1251. A return spring 13 is set in the third hole 1251. The right end of the return spring 13 stops at the bottom of the third hole 1251, and the left end of the return spring 13 stops at the stop portion 533. Therefore, when the second shift member 400 pushes the auxiliary retaining member 530 to move synchronously to the right and switches the gear position of the vehicle to N gear (as shown in FIG. Figure 9a As shown), the driver withdraws the operating force. At this time, under the action of the return spring 13, the auxiliary retaining member 530 and the second shift member 400 are moved to the left side of the housing 100, so as to move the second shift member 400 and the auxiliary retaining member 530 to the position before the driver applies the operating force (the operating force for switching the N gear) (as shown). Figure 3a shown).

[0080] like Figure 3e 、 Figure 13As shown, second rotation guide grooves 532 are formed on the inner surfaces of the front and rear sides (i.e., opposite sides) of the second receiving chamber 531. A second slider 420 corresponding to the second rotation guide groove 532 is provided at the right end (i.e., the second end) of the second shift member 400. That is, a second slider 420 is provided on both the front and rear sides of the second shift member 400. The second rotation guide groove 532 allows the second slider 420 to slide within it. When the second slider 420 is located in the second rotation guide groove 532, the second shift member 400 can rotate relative to the auxiliary retaining member 530 within the second receiving chamber 531, that is, relative to the housing 100. At the same time, when the second shift member 400 rotates, the second slider 420 is restricted by the second rotation guide groove 532, preventing the second shift member 400 from moving leftward or rightward relative to the auxiliary retaining member 530. As a result, the right end of the second shift member 400 is constantly retained in the second receiving chamber 531.

[0081] like Figure 3e As shown, the bottom of the second rotation guide groove 532 is formed as a second rotation guide plane 5321. The middle of the second rotation guide plane 5321 is recessed in a direction away from the second shifting member 400 to form a second turning portion 5321a. In other words, the second rotation guide plane 5321 is divided into two parts by the second turning portion 5321a, and both parts are flat.

[0082] Each second slider 420 includes a second slider body 421, a second hole 422, a second spring 423, and a second interfering telescopic head 424. The second slider body 421 is formed with the second hole 422, and the second spring 423 is disposed within the second hole 422. The first end of the second interfering telescopic head 424 is positioned within the second hole 422, and the second end of the second interfering telescopic head 424 is capable of close contact with the second rotation guide plane 5321. Specifically, one end of the second spring abuts against the bottom of the second hole 422, while the other end supports the second interfering telescopic head 424, ensuring that the second end of the second interfering telescopic head 424 is in constant close contact with the second rotation guide plane 5321.

[0083] like Figure 3e 、 Figure 7b 、 Figure 8bAs shown, under the action of the second spring 423 and the second abutting telescopic head 424, the second shift element 400 can be kept in the second stable position. The second stable position is the position where the second turning guide plane 5321 corresponds to the second turning portion 5321a of the second slider 420, that is, the second abutting telescopic head 424 of the second slider 420 is in close contact with the second turning portion 5321a of the second turning guide plane 5321. In other words, when the driver does not apply a forward or backward operating force to the second shift element 400, the second shift element 400 does not rotate, at this time, the second slider 420 corresponds to the second turning portion 5321a in the second turning guide groove 532, and the second shift element 400 is in the second stable position. When the driver applies a forward or backward operating force to the second shift element 400, the second shift element 400 rotates forward or backward around the axis X, and thus can be switched to the D gear or the R gear of the vehicle. In this process, the two second sliders 420 respectively slide in the second turning guide groove 532 from the second turning portion 5321a, wherein one second slider 420 slides upward and the other second slider 420 slides downward. At this time, the second abutting telescopic head 424 moves toward the bottom of the second hole 422, and at the same time the second spring 423 is compressed by the second abutting telescopic head 424. When the driver withdraws the operating force, the second spring 423 gradually expands and pushes the second abutting telescopic head 424 to move in the second hole 422 to the outside of the second hole 422, and exerts a pressure on the second turning guide plane 5321. In this process, the second abutting telescopic head 424 is subjected to the reaction force of the second turning guide plane 5321, which promotes the rotation of the second shift element 400, and the rotation direction is opposite to that of the second shift element 400 when the driver operates, until the second abutting telescopic head 424 moves to the first turning portion 3111a, that is, the position where the second slider 420 corresponds to the second turning portion 5321a, at this time, the vehicle will be successfully switched to the D gear or the R gear.

[0084] The shift device 10 further comprises a first plate 11 and a second plate 12.

[0085] As shown in Figure 1 , Figure 3a , the first plate 11 is located below the first shift element 200 and has a first through hole 1101 through which the first fixed pin 320 passes. The bottom of the first shift element 200 is formed with a baffle portion 270, which can abut against the right end of the first plate 11, that is, the baffle portion 270 is located on the right side of the first plate 11 and extends downward to abut against the first plate 11.

[0086] As shown in Figure 1 , Figure 3a Figure 14As shown, the second plate member 12 is located below the auxiliary retaining member 530, and has a second through hole 1201 for the second fixing pin 520 to pass through, and a through hole 1202 extending through the second plate member 12. The bottom of the auxiliary retaining member 530 is formed with a limiting portion 534, which can extend into the through hole 1202, and under the elastic force of the return spring 13, limit the leftward movement of the auxiliary retaining member 530. That is, under the limiting of the limiting portion 534, the auxiliary retaining member 530 and the second shift member 400 can only move rightward, but cannot move leftward.

[0087] As shown, Figure 3a The first plate member 11 and the second plate member 12 are provided below with a detection module 600. The detection module 600 is arranged at the bottom of the lower shell 120, and is located in the accommodating cavity of the shell 100. The detection module 600 is connected to the control system of the vehicle through a line, to transmit the signal of the shift to the control system of the vehicle.

[0088] The detection module 600 is provided with a first sensor 610, and the bottom of the first shift member 200 is provided with a first trigger element 280 corresponding to the first sensor 610. As shown, Figure 4b 、 Figure 5b The first trigger element 280 can move in the front-back direction relative to the first sensor 610 with the rotation of the first shift member 200, and when the first sensor 610 detects that the first trigger element 280 moves in the front-back direction, a signal of switching the driving mode is sent to the control system of the vehicle. As shown, Figure 6a The first trigger element 280 can also move rightward relative to the first sensor 610 with the movement of the first shift member 200, and when the first sensor 610 detects that the first trigger element 280 moves rightward, a signal of switching to P gear is sent to the control system of the vehicle.

[0089] As shown, Figure 3a The detection module is also provided with a second sensor 620, and the bottom of the second shift member 400 is provided with a second trigger element 430 corresponding to the second sensor 620. As shown, Figure 7a The second trigger element 430 can move backward relative to the first sensor 610 with the forward rotation of the second shift member 400, and when the second sensor 620 detects that the second trigger element 430 moves backward, a signal of switching to D gear is sent to the control system of the vehicle. As shown, Figure 8a The second trigger element 430 can also move forward relative to the first sensor 610 with the backward rotation of the second shift member 400, and when the second sensor 620 detects that the second trigger element 430 moves forward, a signal of switching to R gear is sent to the control system of the vehicle. As shown, Figure 9aAs shown, the second trigger element 430 can move right relative to the first sensor 610 with the right movement of the second shift element 400, and the second sensor 620 sends a signal to the control system of the vehicle to switch to the N gear when detecting the right movement of the second trigger element 430.

[0090] In the above embodiments, the first trigger element 280 and the second trigger element 430 can be magnets. The first sensor 610 and the second sensor 620 can be Hall effect sensors. The circuit board can be a Printed Circuit Board (PCB). The Hall effect sensors send the detection result information to a Microcontroller Unit (MCU) of the PCB. The MCU can output a P gear, a D gear, an R gear or an N gear signal, or output a signal to switch the driving mode of the vehicle according to the detection result of the Hall effect sensors.
