Description

Technical Field

[0001] The present invention relates to the technical field of vehicle shifting, and in particular to a vehicle shifting device and a shifting method thereof. Background Art

[0002] Unlike conventional mechanical shift systems, the Shift by Wire (SBW) system (i.e., the vehicle electronic shift system) does not have a mechanical connection structure such as a cable connecting the transmission to a shift device (e.g., a shift lever, a button, a knob, or a dial). The SBW system can perform electronic shift control in a manner in which the transmission control unit (TCU) receives a signal generated during the operation of the electronic shift device (e.g., a shift lever, a button, a knob, or a dial). Therefore, the automatic transmission based on the SBW system can transmit the driver's shift intention as an electrical signal to the TCU through a simple operation of the electronic shift device (e.g., a shift lever, a button, a knob, or a dial), thereby making it easier to shift to the parking (Park, P) gear, the neutral (Neutral, N) gear, the reverse (Reverse, R) gear, and the driving (Drive, D) gear. In addition, due to its compact size, the electronic shift device can ensure a spacious space between the driver's seat and the co-pilot seat.

[0003] The shift operation types in the electronic shift system can be exemplarily divided into a dial type using a dial, a button type using a button, and a knob type using a knob. However, the current electronic shift device has a single form and has the disadvantage of inconvenient operation. The driver must concentrate on avoiding mistakes when shifting gears, making the driver more tired due to shifting gears.

[0046] The implementation scheme of the present invention is described in detail below. This implementation scheme is implemented on the premise of the technical scheme of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the implementation scheme described below.

[0047] Figure 1 Schematic diagram of the overall structure of the gear shifting device of a vehicle according to various embodiments of the present invention. Figure 1 As shown, the shifting device of the vehicle includes a base plate 100, a shifting arm 200 and a selection button 300. The shifting arm 200 can move and rotate on the base plate 100, and the selection button 300 is connected to the shifting arm 200. When the shifting arm 200 is moved by an external operating force applied to the selection button 300, the gear position is switched between the neutral (Neutral, N) gear and the driving (Drive, D) gear, and when the shifting arm 200 is rotated by an external operating force applied to the selection button 300, the gear position is switched between the neutral (N) gear and the reverse (R) gear or between the reverse (R) gear and the driving (D) gear. Therefore, according to the embodiment of the present invention, the driver only needs to operate once to realize the shifting between the N gear, the R gear and the D gear, which is easy and convenient to operate, and the shifting mode includes both movement and rotation, which can better distinguish different gear information and reduce erroneous operations during shifting.

[0048] Figure 2 Schematic diagram of a shifting pattern of a shifting device of a vehicle according to various embodiments of the present invention. Figure 2 As shown, a motion path is provided on the substrate 100, and an operating position for shifting to the N gear, an operating position for shifting to the R gear, and an operating position for shifting to the D gear are arranged on the motion path. The shift arm 200 moves or rotates along the motion path. Specifically, the motion path includes a straight path 10 and an arc path 20, a non-operating position Null is provided on the straight path 10, a first operating position N is provided at an end on one side of the non-operating position Null, and a second operating position D is provided at an end on the other side of the non-operating position Null, the arc path 20 is formed with the first operating position N and the second operating position D as ends, and a third operating position R is provided on the arc path 20.

[0049] The distance between the non-operating position Null and the first operating position N may be equal to the distance between the non-operating position Null and the second operating position D. For example, the line connecting the third operating position R and the non-operating position Null and the line connecting the first operating position N and the second operating position D (i.e., the straight path 10) are perpendicular to each other, and the distance between the third operating position R and the non-operating position Null is equal to the distance between the first operating position N and the non-operating position Null, and is also equal to the distance between the second operating position D and the non-operating position Null.

[0050] The first operating position N is an operating position for shifting to the N gear, the second operating position D is an operating position for shifting to the D gear, and the third operating position R is an operating position for shifting to the R gear. The shift arm 200 has a first end a and a second end b along the length direction. Therefore, based on the movement of the first end a and the second end b of the shift arm 200 on the straight path 10, the gear position switches between the N gear and the D gear. When the second end b of the shift arm 200 is located at the non-operating position Null, the shift arm 200 can be rotated with the non-operating position Null as the center of rotation, and as the shift arm 200 rotates so that the first end a moves along the arc path 20, the gear position can be switched between the N gear and the R gear or between the R gear and the D gear. When the first end a of the shift arm 200 is located at the non-operating position Null, the shift arm 200 can still be rotated with the non-operating position Null as the center of rotation, and as the shift arm 200 rotates so that the second end b moves along the arc path 20, the gear position can be switched between the N gear and the R gear or between the R gear and the D gear.

[0051] In combination with a shift by wire (SBW) system, the shift device of the vehicle may further include a sensor and a controller, the sensor being used to detect a position change of the shift arm 200 that moves or rotates along the motion path, and the controller being used to receive detection information from the sensor and output a shift signal, thereby controlling the transmission according to the operation of the shift arm 200. Therefore, by operating the shift arm 200, the shift signal output from the controller may be input to the transmission for shifting.

[0052] In an embodiment of the present invention, the gear shifting device of a vehicle may further include a circuit board. Figure 3 Schematic diagram of the structure between the shift arm, the substrate and the circuit board according to an embodiment of the present invention. Figure 3As shown, the bottom of the first end and the second end of the shift arm 200 are respectively provided with sensor trigger elements 210, specifically, the bottom of the first end of the shift arm 200 is provided with a first sensor trigger element 211, and the bottom of the second end is provided with a second sensor trigger element 212. The circuit board 400 is arranged below the substrate 100, and the circuit board 400 has a sensor 410 for detecting the sensor trigger element 210 and is arranged at least corresponding to the first operating position, the second operating position and the third operating position. In a specific embodiment, the circuit board 400 has a first sensor 411 arranged corresponding to the first operating position, a second sensor 412 arranged corresponding to the second operating position, and a third sensor 413 arranged corresponding to the third operating position, but the present invention is not limited thereto. The first sensor 411, the second sensor 412 and the third sensor 413 can be formed separately and arranged on the circuit board 400, or they can be formed as a whole and arranged on the circuit board 400. Each of the first sensor 411, the second sensor 412 and the third sensor 413 is configured to detect the first sensor trigger element 211 or the second sensor trigger element 212, and the circuit board 400 (specifically, the controller of the circuit board 400) outputs a shift signal of one of the R gear, the N gear and the D gear according to the sensor 410 (specifically, the first sensor 411, the second sensor 412 and the third sensor 413) detecting the sensor trigger element 210 (specifically, the first sensor trigger element 211 or the second sensor trigger element 212). Specifically, when the first sensor 411 set corresponding to the first operating position detects one of the first sensor trigger element 211 and the second sensor trigger element 212, the circuit board 400 outputs a shift signal for the N gear; when the second sensor 412 set corresponding to the second operating position detects one of the first sensor trigger element 211 and the second sensor trigger element 212, the circuit board 400 outputs a shift signal for the D gear; when the third sensor 413 set corresponding to the third operating position detects one of the first sensor trigger element 211 and the second sensor trigger element 212, the circuit board 400 outputs a shift signal for the R gear.

[0053] For example, notches 110 may be formed respectively at positions on the substrate 100 corresponding to the first sensor 411 , the second sensor 412 , and the third sensor 413 , so that there is no shielding of the substrate 100 between the sensor triggering element 210 and the sensor 410 .

[0054] In the above embodiment, the sensor trigger element 210 can be a magnet, and the magnet can be a permanent magnet or an electromagnet. The sensor 410 can be a Hall effect sensor, but the present invention is not limited thereto. For example, the sensor 410 can be any magnetic field response sensor that can detect magnetic flux and generate a signal indicating the presence and density of magnetic flux.

[0055] The circuit board 400 may be a printed circuit board (PCB). Accordingly, the controller may be a microcontroller unit (MCU) of the PCB, and the Hall effect sensor sends a pulse width modulation (PWM) signal to the MCU due to the sensed magnetic flux. The MCU may output a shift signal of one of the N gear, the D gear, or the R gear according to the PWM signal.

[0056] Hereinafter, the structure in which the shift arm moves and rotates on the base plate will be described in detail. Figure 4 is a schematic structural diagram of a gear shifting device for a vehicle according to an embodiment of the present invention. Figure 5 yes Figure 4 The structural exploded view of the gear shifting device of the vehicle shown in FIG. Figure 4 and Figure 5 As shown, a mounting hole 250 is formed in the center of the shift arm 200, and an insertion column 310 for inserting into the mounting hole 250 is provided at the bottom of the selection button 300, so that the selection button 300 can be connected to the shift arm 200. When an external operating force is applied to the selection button 300, the selection button 300 can drive the shift arm 200 to move, that is, the driver can move or rotate the shift arm 200 by operating the selection button 300.

[0057] Figure 6 is a schematic structural diagram of a shift arm and a base plate according to an embodiment of the present invention. Figure 7 is along Figure 6 A cross-sectional view taken along line AA in FIG. Figure 8 is along Figure 6 A cross-sectional view taken along line BB in FIG. Figures 4 to 8 A guide groove 120 for forming a movement path is formed on the substrate 100, and the guide groove 120 includes a first vertical groove portion 121 formed along the extension direction of the straight path and a second vertical groove portion 122 formed along the extension direction of the arc path.

[0058] Accordingly, at least one guide block 220 is formed at the bottom of the shift arm 200, and the guide block 220 is used to be inserted into the guide groove 120 of the base plate 100, and can match the guide groove 120 on the base plate 100. Specifically, the guide block 220 includes a vertical portion 221 connected to the bottom of the shift arm 200, and the vertical portion 221 matches the first vertical groove portion 121 and the second vertical groove portion 122, so that the shift arm 200 can move along a straight path or rotate along an arc path on the base plate 100.

[0059] In the embodiment of the present invention, two first vertical groove portions 121 may be provided at a predetermined distance, and the predetermined distance does not exceed the length of the shift arm 200 in the width direction. Accordingly, two vertical portions 221 are provided at a distance at the bottom of one end of the shift arm 200 in the width direction, and two vertical portions 221 are provided at a distance at the bottom of the other end of the shift arm 200 in the width direction.

[0060] Reference Figures 7 and 8 In order to prevent the shift arm 200 from falling out of the base plate 100, the guide groove 120 may include a transverse groove portion 123 connected to the first vertical groove portion 121 and formed in the transverse direction, and the transverse groove portion 123 may extend toward the central axis of the shift arm 200 in the width direction, but the present invention is not limited thereto, and the transverse groove portion 123 may also extend in a direction away from the central axis in the width direction. Accordingly, the guide block 220 includes a first transverse portion 222, which is connected to the end portion of the vertical portion 221 and is configured to match the transverse groove portion 123.

[0061] Similarly, the guide groove 120 may further include an arc groove portion 124 that is connected to the second vertical groove portion 122 and formed along the circumferential direction, and the arc groove portion 124 may extend outward along the circumferential direction of the second vertical groove portion 122. Correspondingly, the guide block 220 includes a second transverse portion 223 that is connected to the terminal end of the vertical portion 221 and is configured to match the arc groove portion 124.

[0062] Fig. 9 Schematic diagram of the structure of the shift arm according to an embodiment of the present invention. Fig. 9 As shown, four guide blocks 220 are provided at the bottom of the shift arm 200. Two guide blocks 220 are provided at intervals along the width direction at the bottom of one end of the shift arm 200, and two guide blocks 220 are provided at intervals along the width direction at the bottom of the other end of the shift arm 200. Each guide block 220 includes a vertical portion 221, a first transverse portion 222, and a second transverse portion 223, so that the orthographic projections of the guide block 220 on the horizontal plane and on the vertical plane are both L-shaped.

[0063] As described above, the guide groove 120 on the base plate 100 provides a movement path for the shift arm 200. In addition, the shift device of the vehicle may further include a stopper assembly 500, which is connected to the shift arm 200 and is configured to limit the movement or rotation of the shift arm 200 under the action of an external operating force, so that the first end and the second end of the shift arm 200 can maintain a stable state at the corresponding operating position, so that the sensor 410 on the circuit board 400 can detect the sensor trigger element 210 at the bottom of the first end or the second end of the shift arm 200, and then the circuit board 400 can output a shift signal. Fig.10 Schematic diagram of the use state of the stop assembly according to an embodiment of the present invention. Fig.10 As shown, the stop assembly 500 includes a central shaft 510 , an inner ring 520 , an outer ring 530 , and a stop element 540 .

[0064] like Figure 2 and Figure 3 As shown, in order for the circuit board 400 to output the N gear signal, one of the first end a and the second end b of the shift arm 200 needs to be kept stable at the first operating position N, so that the first sensor 411 on the circuit board 400 can detect the first sensor trigger element 211 or the second sensor trigger element 212 located at the bottom of the end of the shift arm 200. In order for the circuit board 400 to output the D gear signal, one of the first end a or the second end b of the shift arm 200 needs to be kept stable at the second operating position D, so that the second sensor 412 on the circuit board 400 can detect the first sensor trigger element 211 or the second sensor trigger element 212 located at the bottom of the end of the shift arm 200. The above operation can be achieved by keeping one of the first end a and the second end b of the shift arm 200 stable at the non-operating position Null (the middle position between the first operating position N and the second operating position D). That is to say, when the first end a of the shift arm 200 remains stable in the non-operating position Null, the second end b of the shift arm 200 can be located in the first operating position N or the second operating position D, and the second end b of the shift arm 200 can remain stable. When the second end b is located in the first operating position N, the circuit board 400 outputs an N gear signal, and when the second end b is located in the second operating position D, the circuit board 400 outputs a D gear signal. When the second end b of the shift arm 200 remains stable in the non-operating position Null, the first end a of the shift arm 200 can be located in the first operating position N or the second operating position D, and the first end a of the shift arm 200 can remain stable. When the first end a is located in the first operating position N, the circuit board 400 outputs an N gear signal, and when the first end a is located in the second operating position D, the circuit board 400 outputs a D gear signal.

[0065] In an embodiment of the invention, the central axis 510 is disposed in a non-operating position on the base plate 100. The shift arm 200 has a movement stop profile at the first end and the second end, respectively. The central axis 510 is provided with a stop element 540. Specifically, the projection of the stop element 540 on the base plate 100 is located on a straight line that is perpendicular to the straight path and passes through the non-operating position. The stop element 540 is inserted into the movement stop profile so that the first end or the second end of the shift arm 200 is limited to the first operating position or the second operating position during the movement of the shift arm 200.

[0066] In a specific embodiment, Fig.112 is a schematic structural diagram of a shift arm when the first end portion is restricted to a first operating position according to an embodiment of the present invention. Fig.12 yes Fig.11 Bottom view of . Fig.13 is along Fig.12 A cross-sectional view taken along line CC in FIG. Figure 4 , Figure 5 as well as Figures 11 to 13 The inner surface of the shift arm 200 is formed with a sliding contact surface 230, and the extension direction of the sliding contact surface 230 is parallel to the straight path. Positions of the sliding contact surface 230 close to the first end of the shift arm 200 and the second end of the shift arm 200 are respectively provided with positioning grooves 231, and the positioning grooves 231 serve as the above-mentioned movement stop profile. The central shaft 510 is set to pass through the non-operating position on the substrate 100, and accordingly, the substrate 100 is provided with an axial hole 140 for the central shaft 510 to pass through corresponding to the non-operating position. The stop element 540 includes a contact telescopic head 541 and an elastic member 542. The central shaft 510 is provided with a receiving hole 511 extending in the radial direction. The contact telescopic head 541 is arranged in the receiving hole 511 of the central shaft 510, and the head of the contact telescopic head 541 can extend from the receiving hole 511 and face the sliding contact surface 230. The elastic member 542 is disposed in the receiving hole 511 to elastically support and resist the expansion and contraction head 541 .

[0067] When the shift arm 200 moves under the action of external operating force, the abutment expansion joint 541 can move along the sliding contact surface 230. The elastic member 542 applies elastic force to the abutment expansion joint 541 to make the abutment expansion joint 541 extend from the receiving hole 511, so that the abutment expansion joint 541 can be inserted into the positioning groove 231. When the abutment expansion joint 541 is inserted into the positioning groove 231 near the second end, that is, when the second end is closed, the elastic member 542 is pressed against the second end of the shift arm 200. Fig.12 In the shown state, the second end of the shift arm 200 remains stable in the non-operating position, and the first end of the shift arm 200 is located in the first operating position and can remain stable, so that the first sensor 411 on the circuit board 400 can detect the first sensor trigger element 211 located at the bottom of the first end of the shift arm 200.

[0068] When the retractable head 541 is inserted into the positioning groove 231 near the first end, the first end of the shift arm 200 is located in the second operating position and can remain stable, so that the second sensor 412 on the circuit board 400 can detect the second sensor trigger element 212 at the bottom of the second end of the shift arm 200.

[0069] For example, the shift arm 200 may be configured to be symmetrical with respect to the central axis in the length and width directions, and the sliding contact surface 230 includes two sliding contact surfaces 230 that are symmetrical with respect to the central axis in the length direction of the shift arm 200. The positioning groove 231 includes two mutually symmetrical positioning grooves 231 near the first end of the shift arm 200 and two mutually symmetrical positioning grooves 231 near the second end of the shift arm 200. Accordingly, the number of the accommodating holes 511 is set to two, and two stopper elements 540 are respectively disposed in each accommodating hole 511, and the elastic member 542 may be a spring.

[0070] like Fig.12 As shown, two stopper elements 540 are provided, and their projection on the substrate 100 is located in the line segment MN on the line CC, wherein the line CC is perpendicular to the straight path and passes through the non-operating position, and the points M and N are two intersection points of the projection of the shift arm 200 on the substrate 100 and the line CC. However, the present invention is not limited thereto, and a sliding contact surface may also be formed on the bottom surface of the shift arm 200, and the stopper element 540 may be provided as one and may be located at the midpoint of the line segment MN.

[0071] The outer peripheral surface of the central axis 510 forms a limiting boss 512 that is symmetrically distributed relative to the line CC. The shift arm 200 is formed with a shift stop surface 240 on the inner surface near the first end position and near the second end position, respectively. The shift stop surface 240 connects two sliding contact surfaces 230, and the two sliding contact surfaces 230 are symmetrically positioned relative to the central axis of the length direction of the shift arm 200. The shift stop surface 240 can be configured as a multi-segment surface shape composed of multiple surfaces, one of which 241 is used to contact the end of the limiting boss 512 when the contact telescopic head 541 is inserted into the positioning groove 231. In order to switch the vehicle from the D gear to the N gear, the shift arm 200 is moved as shown in the figure under the action of an external operating force. Fig.12 As shown in FIG. 5 , the rotatable end 540 moves to the left side so as to abut against the telescopic head 541 and then can be inserted into the positioning groove 231 close to the second end position. Fig.12 The schematic diagram shows the state when the contact telescopic head 541 is inserted into the positioning groove 231 near the second end position. At the same time, the limiting boss 512 on the central shaft 510 can contact the surface 241 of the gear blocking surface 240 (the gear blocking surface 240 is located near the second end position), and the shift arm 200 can no longer move to Fig.12Therefore, the driver can sense that the shift arm 200 cannot move any further, thereby determining that the shift to the N gear has been achieved. Similarly, since the shift arm 200 is also formed with a gear stop surface 240 on the bottom surface near the first end, when the vehicle switches from the N gear to the D gear, the limiting boss 512 can contact with the surface 241 included in the gear stop surface 240 (the gear stop surface 240 is located near the first end), and the driver can also sense that the shift arm 200 cannot move any further, thereby determining that the shift to the D gear has been achieved.

[0072] For example, some of the surfaces 241, 242, and 243 among the multiple surfaces can form a limiting groove 244 that matches the shape of the limiting boss 512, and the limiting boss 512 can be inserted into the limiting groove 244. Therefore, when one end of the shift arm 200 is located in the non-operating position, the shift arm 200 takes the non-operating position as the rotation center, and the other end rotates along an arc path under the action of an external operating force, the connection structure between the limiting groove 244 and the limiting boss 512 can limit the position of the end of the shift arm 200 located in the non-operating position, so that the abutting telescopic head 541 is not easy to escape from the positioning groove 231, so that the rotation process of the shift arm 200 is more stable.

[0073] In another example, all of the multiple surfaces can form a receiving groove that matches the shape of the outer peripheral surface of the central shaft 510. Therefore, when the abutting expansion head 541 is inserted into the positioning groove 231, the two arc portions of the central shaft 510 adjacent to the limiting boss 512 can also contact the surfaces 245 and 246 among the multiple surfaces of the gear blocking surface 240, thereby enhancing the stability of the shift arm 200 during rotation.

[0074] like Figure 2 and Figure 3 As shown, the shift arm 200 can rotate with the non-operating position Null as the rotation center. As the shift arm 200 rotates, the first end a (or the second end b) rotates along the arc path 20, and the gear position can be switched between the N gear and the R gear or between the R gear and the D gear. Therefore, during the rotation of the shift arm 200, the first end a or the second end b of the shift arm 200 needs to remain stable at the first operating position N, the second operating position D, and the third operating position R, so that the first sensor 411, the second sensor 412, or the third sensor 413 on the circuit board 400 can detect the first sensor trigger element 211 located at the bottom of the first end a of the shift arm 200 or the second sensor trigger element 212 located at the bottom of the second end b of the shift arm 200, and then the circuit board 400 can output a shift signal.

[0075] Therefore, according to an embodiment of the present invention, the inner ring 520 is coaxially disposed on the central shaft 510 and is capable of rotating integrally with the central shaft 510. The outer ring 530 is arranged concentrically relative to the inner ring 520. The inner circumferential surface of the outer ring 530 has at least three rotation stop profiles, and the positional relationship of these rotation stop profiles on the outer ring 530 corresponds to the positional relationship of the first operating position, the second operating position, and the third operating position on the arc path. The inner ring 520 is provided with a stop element 540, and the stop element 540 is inserted into the rotation stop profile, so that during the rotation of the shift arm 200, the first end or the second end of the shift arm 200 is limited to the first operating position, the second operating position, or the third operating position.

[0076] In a specific embodiment, Figure 5 As shown, the upper end of the central shaft 510 forms a limiting boss 512 for inserting into the limiting groove 244 of the gear blocking surface 240, the outer circumferential surface of the lower end of the central shaft 510 forms an outer spline 513, and the inner circumferential surface of the inner ring 520 forms an inner spline 521. The inner spline 521 of the inner ring 520 meshes with the outer spline 513 of the central shaft 510, so that the inner ring 520 is coaxially arranged on the central shaft 510 and can rotate integrally with the central shaft 510.

[0077] Fig.14 Schematic diagram of the structure of a stopper assembly according to an embodiment of the present invention. Fig.15 is along Fig.14 A cross-sectional view taken along line DD in FIG. Fig.16A is along Fig.14 A cross-sectional view taken along line EE in FIG. Figure 4 , Figure 5 , Figures 14 to 16A The inner ring 520 is formed with a receiving hole 522 extending in the radial direction. The stop element 540 includes a contact expansion head 541 and an elastic member 542. The contact expansion head 541 is arranged in the receiving hole 522 of the inner ring 520, and the head of the contact expansion head 541 can extend from the receiving hole 522. The elastic member 542 is arranged in the receiving hole 522 for elastically supporting the contact expansion head 541.

[0078] The inner surface of the outer ring 530 is provided with an annular guide groove 531 extending in the circumferential direction, and a positioning recess 532 is formed in the annular guide groove 531 corresponding to the positional relationship between the first operating position, the second operating position and the third operating position, and the positioning recess 532 serves as a rotation stop profile. Since the distances between the first operating position, the second operating position and the third operating position and the non-operating position are respectively equal, the connecting line of the third operating position and the non-operating position is perpendicular to the connecting line of the first operating position and the second operating position, so that the connecting line of the first operating position and the second operating position along the arc path is a semicircular arc with the non-operating position as the center, and the connecting line of the first operating position (or the second operating position) and the third operating position along the arc path is a quarter-circular arc with the non-operating position as the center. Therefore, according to the positional relationship between the first operating position, the second operating position and the third operating position, a positioning recess 532 can be formed every 90° in the annular guide groove 531. In a specific embodiment, the annular guide groove 531 is composed of four identical arc segments 533 , and the intersection between two adjacent arc segments 533 forms a positioning recess 532 , but the shape of the annular guide groove 531 of the present invention is not limited thereto.

[0079] When one end of the shift arm 200 is caused to rotate on an arc path under the action of an external operating force, the other end of the shift arm 200 can drive the central shaft 510 so that the central shaft 510 rotates around its own axis. The rotation of the central shaft 510 can drive the inner ring 520 to rotate, so that the interference telescopic head 541 set in the accommodating hole 522 of the inner ring 520 can move along the annular guide groove 531. The elastic member 542 applies an elastic force to the interference telescopic head 541 to make the interference telescopic head 541 extend from the accommodating hole 522, so that the interference telescopic head 541 can be inserted into the positioning recess 532. Therefore, the first end or the second end of the shift arm 200 can maintain a stable state in the first operating position, the second operating position and the third operating position. For example, when the interference telescopic head 541 is inserted into Fig.16A When the first end portion (or the second end portion) of the shift arm 200 is positioned in the left and right positioning recesses 532 , the first end portion (or the second end portion) of the shift arm 200 can be kept stable in the first operating position or the second operating position. Fig. 16B is a schematic diagram showing the structure between the inner ring, the stop element and the outer ring in another state. Fig.16A In the state shown, the shift arm 200 is rotated counterclockwise or clockwise by an external operating force, and the retractable head 541 is inserted as shown in FIG. Fig. 16B When the first end (or the second end) of the shift arm 200 is positioned in the upper and lower positioning recesses 532 as shown in FIG. 5 , the first end (or the second end) of the shift arm 200 can be kept stable at the third operating position.

[0080] The shifting device of the vehicle may further include a box body 600, so that the shifting device can be installed in the space between the driver's seat and the co-pilot seat. The box body 600 includes an upper box body 610 and a lower box body 620 that can be combined with each other. Specifically, the upper box body 610 and the lower box body 620 can be connected by a buckle structure. Fig.17 2 is a schematic structural diagram of a vehicle shifting device without an upper box body and a base plate according to an embodiment of the present invention. Figure 4 , Figure 5 , Fig.15 as well as Fig.17 The lower box body 620 includes a bottom plate portion 621 and a connecting portion 622, and the bottom plate portion 621 is disposed below the circuit board 400. A slot 534 is formed on the outer surface of the outer ring 530, one end of the connecting portion 622 is connected to the bottom plate portion 621, and the other end is accommodated in the slot 534 of the outer ring 530 and matches the shape of the slot 534 of the outer ring 530, so that the outer ring 530 is fixed on the lower box body 620. A through hole 420 is formed in the center of the circuit board 400, and the circuit board 400 is sleeved on the outer ring 530 or the outside of the central axis 510 through the through hole 420. The upper box body 610 covers the substrate 100, and the upper box body 610 is formed with an opening 611, so that the selection button 300 can be exposed from the opening 611 for the driver to operate. Since the selection button 300 is connected to the center of the shift arm 200, and the movement path of the selection button 300 is approximately in the shape of a semicircle, the opening 611 of the upper box body 610 can be substantially in the shape of a semicircle. The upper box body 610 can also be marked with gear position marks "N", "D" and "R" corresponding to the first operating position, the second operating position and the third operating position on the base plate 100 to help the driver shift gears.

[0081] Back to Figure 1 In various embodiments of the present invention, the shift device of the vehicle may further include a Park (P) gear button 810, which is separated from the motion path and operated separately. The circuit board is configured to receive an operation signal of the Park gear button 810 and output a shift signal of the P gear, so that the driver can select the P gear position through a separate operation.

[0082] In addition, in various embodiments of the present invention, other function buttons such as auto hold and drive mode can be integrated into the shift by wire (SBW) system to reduce development costs and save space in the vehicle console. Therefore, the shift device of the vehicle can further include a first function button and a second function button, the first function button can be an auto hold button 820, and the second function button can be a drive mode button 830, the auto hold button 820 and the drive mode button 830 are set to be separated from the motion path and the parking gear button, and operate separately. The circuit board 400 is configured to receive the operation signals of the auto hold button 820 and the drive mode button 830, and output the corresponding control signals. Therefore, the driver can select the auto hold and drive modes by operating the shift device of the vehicle.

[0083] For example, back to Figure 5 The circuit board 400 may be covered with a damping sheet 700, and the damping sheet 700 has elasticity, for example, the damping sheet 700 may be made of rubber or silicone. The parking gear button 810, the automatic parking button 820, and the driving mode button 830 are respectively arranged on the damping sheet 700. Specifically, each of the parking gear button 810, the automatic parking button 820, and the driving mode button 830 passes through the button opening 612 of the upper box body 610 and the button opening 130 on the substrate 100 and is arranged on the damping sheet 700, so that when the driver presses the button, he can feel the resistance to increase the feel when pressing the button. However, the parking gear button 810, the automatic parking button 820, and the driving mode button 830 are not limited thereto, and these buttons can be configured as other different types of switches.

[0084] 18A to 18E 2 is an operational schematic diagram of a shifting device for a vehicle according to an embodiment of the present invention. 18A to 18E The shift device according to the embodiment of the present invention is a rocker arm structure, and the shift information can be distinguished by different shift modes, which facilitates the shift and reduces the wrong operation. In addition, the development cost is reduced and the space of the vehicle console is saved by integrating the automatic parking button and the driving mode button in the shift device. The driver can switch the vehicle to the P gear by pressing the parking gear button, switch the gear between the N gear and the D gear by moving the selection knob, and switch the gear between the N gear and the R gear or between the D gear and the R gear by turning the selection knob.

[0085] In one case, referring to Fig.18A and Fig.18BWhen the driver wants to shift from N gear to D gear, the driver can push the selector button to the right, move the first end of the shift arm away from the first operating position N, and move the second end to the second operating position D. At this time, the vehicle is switched to D gear. Conversely, when the driver wants to shift from D gear to N gear, the driver can push the selector button to the left, move the second end of the shift arm away from the second operating position D, and move the first end to the first operating position N. At this time, the vehicle is switched to N gear.

[0086] Then, refer to Fig.18B and Fig.18C When the driver wants to shift from D gear to R gear, the driver can rotate the selector button clockwise, and the second end of the shift arm rotates from the second operating position D to the third operating position R. At this time, the vehicle is switched to the R gear. Conversely, when the driver wants to shift from R gear to D gear, the driver can rotate the selector button counterclockwise, and the second end of the shift arm rotates from the third operating position R to the second operating position D. At this time, the vehicle is switched to the D gear.

[0087] Then, refer to Fig.18C and Fig.18D When the driver wants to shift from R gear to N gear, the driver can rotate the selector button clockwise, and the second end of the shift arm rotates from the third operating position R to the first operating position N. At this time, the vehicle is switched to N gear. Conversely, when the driver wants to shift from N gear to R gear, the driver can rotate the selector button counterclockwise, and the second end of the shift arm rotates from the first operating position N to the third operating position R. At this time, the vehicle is switched to R gear.

[0088] In another case, refer to Fig.18A and Fig.18D When the driver wants to shift from N gear to R gear, the driver can rotate the selector button counterclockwise, and the first end of the shift arm rotates from the first operating position N to the third operating position R. At this time, the vehicle is switched to the R gear. Conversely, when the driver wants to shift from R gear to N gear, the driver can rotate the selector button clockwise, and the first end of the shift arm rotates from the third operating position R to the first operating position N. At this time, the vehicle is switched to the N gear.

[0089] Then, refer to Fig.18C When the driver wants to shift from R gear to D gear, the driver can rotate the selector button counterclockwise, and the first end of the shift arm rotates from the third operating position R to the second operating position D. At this time, the vehicle is switched to D gear. Conversely, when the driver wants to shift from D gear to R gear, the driver can rotate the selector button clockwise, and the first end of the shift arm rotates from the second operating position D to the third operating position R. At this time, the vehicle is switched to R gear.

[0090] Then, refer to Fig.18A and Fig.18B When the driver wants to shift from the D gear to the N gear, the driver can push the selector button to the left, move the first end of the shift arm away from the second operating position D, and move the second end to the first operating position N. At this time, the vehicle is switched to the N gear. Conversely, when the driver wants to shift from the N gear to the D gear, the driver can push the selector button to the right, move the second end of the shift arm away from the first operating position N, and move the first end to the second operating position D. At this time, the vehicle is switched to the driving gear.

[0091] Since the bottom of the first end and the second end of the shift arm are both provided with a sensor trigger element 210, the driver does not need to distinguish whether it is the first end of the shift arm or the second end of the shift arm that triggers the gear switch during operation, thereby ensuring that the shift between N gear, R gear and D gear can be achieved with only one operation.

[0092] Reference 18A to 18E When the driver wants to shift from R / D / N gear to P gear, the driver can press the parking gear button. When the driver wants to select automatic parking or driving mode, the driver can press the automatic parking button or the driving mode button.

[0093] In the above embodiment, if Fig.18A As shown, the parking gear button and the like are located at the upper part of the figure, and the third operating position R is located at the lower part of the figure, but the present invention is not limited thereto. Fig.19 FIG. 2 is a schematic diagram of a vehicle shifting device according to another embodiment of the present invention. Fig.19 As shown, the parking gear button and the like are located at the lower part of the figure, and the third operating position R is located at the upper part of the figure.

[0094] In other embodiments of the present invention, the stop assembly can be replaced by a return assembly, and the non-operating position Null is used as a stable state. The driver operates the selector button 300 to move or rotate the shift arm 200, so that the vehicle switches to the corresponding gear position. After the driver releases the selector button 300, the selector button 300 and the shift arm 200 can automatically return to the non-operating position Null.

[0095] In addition, an embodiment of the present invention also provides a shifting method for a vehicle's shifting device, wherein the vehicle's shifting device is the above-mentioned vehicle's shifting device, and the shifting method includes: when the shift arm 200 is moved by an external operating force applied to the selection button 300, the gear position is switched between the N gear and the D gear; when the shift arm 200 is rotated by an external operating force applied to the selection button 300, the gear position is switched between the N gear and the R gear or between the D gear and the R gear.

[0096] According to the embodiment of the present invention, the shifting device of the vehicle is a rocker-arm structure, and the shifting information can be distinguished by different shifting modes. Specifically, the vehicle is switched to the P gear by pressing the parking gear button, the gear is switched between the N gear and the D gear by moving the selection knob, and the gear is switched between the N gear and the R gear or between the D gear and the R gear by turning the selection knob, which can reduce erroneous operations while facilitating the shifting, and ensure that the shifting between the N gear, the R gear and the D gear only requires one operation. In addition, an automatic parking button and a driving mode button are set in the shifting device of the vehicle, and functions such as automatic parking and driving mode are integrated into the SBW, which can reduce development costs, save space for console packaging, and increase convenience.
