[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] It can be known that the development of electronic shifter technology has enhanced the technological sense and driving experience of automobiles, and has promoted the upgrading of the automobile industry and the development of autonomous driving technology. Although electronic shifters have brought many conveniences, they also have some shortcomings. For example, the most common electronic shifter is the knob shifter. The roller structure configured is complex, mostly gear meshing type, with a large number of parts, which increases the probability of problems with the shifter and is not conducive to the maintenance of the shifter; the shifter is large in size and occupies a large space on the dashboard or sub-dashboard, which is difficult to arrange for the entire vehicle, and has more requirements for the molding of the dashboard; multiple electronic components and control units are required, and independent power lines are required to ensure the normal operation of the system.

[0046] In view of the issues mentioned. Please refer to Figure 1 and Figure 2 , Figure 1 An exploded view of the shifting device of the present application is shown; Figure 2 FIG. 2 shows a front cross-sectional view of the shifting device of the present application. Figure 1 and Figure 2 As shown, an embodiment of the present application provides a shift device, which includes: a shift housing; a mechanical shift portion, which is arranged on the shift housing, including a shift handle 3 and a gear switching mechanism, the shift handle 3 is provided with a fixed rotating hub 31, and the gear switching mechanism is provided with multiple required gears; the shift handle 3 switches between the multiple required gears through the fixed rotating hub 31; an electronic shift portion, including multiple shift sensors 11 and a shift receiver, each of the shift sensors 11 is arranged on each of the required gears, and is communicatively connected with the shift receiver, and the shift receiver is used to control the shift actuator to perform the shift operation.

[0047] Specifically, the shift housing provides structural support for other components of this embodiment, that is, the shift handle 3, the gear switching mechanism and the shift sensor 11 are all arranged at different positions of the shift housing, and are fixed as a whole under the sub-instrument panel or the instrument panel, and the shift handle 3 extends out of the shift housing and the sub-instrument panel. The driver moves the shift handle 3 in the gear switching mechanism to switch to the required gear. The gear switching mechanism includes multiple preset required gears, such as parking (P), reverse (R), neutral (N), driving (D), manual mode (M), etc.

[0048] In some embodiments, the gear selector handle 3 can be designed into various shapes, such as a straight rod, a short rod, a curved rod, a rod with a handle or other forms, to facilitate the driver's operation.

[0049] In this embodiment, a fixed rotating hub 31 is provided on the gear selection handle 3 as the rotation center of the gear selection handle 3. The fixed rotating hub 31 can rotate but not move at its installation position, so the gear selection handle 3 connected to the fixed rotating hub 31 can freely rotate and tilt around the fixed rotating hub 31 in multiple directions within a large spatial range. Exemplarily, the fixed rotating hub 31 is provided at the middle and lower part of the gear selection handle 3, the fixed rotating hub 31 and part of the handle body of the gear selection handle 3 are located in the hollow cavity of the gear shift housing, the remaining part of the handle body of the gear selection handle 3 extends out of the gear shift housing, and the fixed rotating hub 31 is rotatably connected in the hollow cavity of the gear shift housing through the cover plate. The gear selection handle 3 can be moved in any direction such as the left front, right front, left rear, right rear, front or rear, and the fixed rotating hub 31 rotates in each corresponding direction in the hollow cavity but is restricted by the cover plate and does not move, so that the gear selection handle 3 is successfully moved to the corresponding position. Therefore, by fixing the rotating hub 31, the gear selector handle 3 is provided with a higher degree of rotational freedom and positioning accuracy, so that the gear selector handle 3 can move smoothly in different directions, improve the smoothness of the gear shifting process, and enhance the operating experience and reliability of the gear shifting process.

[0050] It can be understood that the definition of the fixed rotating hub 31 described here is relative. The so-called fixed rotating hub 31 is fixed relative to the movement of the gear selector handle 3, but the fixed rotating hub 31 remains relatively fixed at its installation position, that is, it can rotate at the installation position but does not change the installation position as the handle moves.

[0051] Exemplarily, a limiting hole is provided on the cover plate, and the fixed rotating hub 31 passes through the limiting hole. The limiting hole forms a rotation space for the fixed rotating hub 31 and limits the rotation range of the fixed rotating hub 31. The cover plate is provided in the shift housing, and the base 2 of the shift housing has a flange 21, and a cover plate mounting hole 14 is provided on the flange 21. A through hole is provided on the cover plate, and the position of the through hole is opposite to the position of the cover plate mounting hole 14. The stud passes through the through hole and extends into the cover plate mounting hole 14, and the cover plate is fastened to the flange 21 of the base 2. The inner edge of the limiting hole is in close contact with the outer edge of the fixed rotating hub 31, thereby clamping and fixing the fixed rotating hub 31.

[0052] More specifically, the cover plate is provided with a separate upper cover plate 6 and a lower cover plate 7, which have the same structure and are positioned opposite to each other. A through hole is provided on the opposite sides of each cover plate, and a cover plate mounting hole 14 is provided on the flange 21 of the base 2 of the shift housing. The lower cover plate 7 is installed first, and the fixed rotating hub 31 is initially fixed on the shift housing, and the fixed rotating hub 31 can be fine-tuned to ensure its correct position. Then, the upper cover plate 6 is superimposed on the lower cover plate 7, and the studs are passed through the upper and lower through holes to connect with the cover plate mounting hole 14 of the shift housing for final fixing, so as to form an upper and lower clamping of the fixed rotating hub 31.

[0053] Therefore, the step-by-step operation of first installing the lower cover plate 7 and then installing the upper cover plate 6 simplifies the assembly process and facilitates installation and adjustment. Similarly, when the fixed rotating hinge 31 needs to be repaired or replaced, the upper cover plate 6 and the lower cover plate 7 can be removed separately, which is more convenient to operate.

[0054] The mechanical shifting unit composed of the above-mentioned gear selection handle 3, fixed rotating hub 31, gear switching mechanism and other components facilitates the driver to select the gear, and maintains the intuitiveness and shifting feel of mechanical gear shifting. In this embodiment, an electronic shifting unit is also provided, and the electronic shifting unit includes a shifting sensor 11 and a shifting receiver, wherein a plurality of shifting sensors 11 are provided on each required gear of the gear switching mechanism, responsible for detecting the position of the gear selection handle 3 and generating a corresponding gear signal, and the shifting receiver receives the signal transmitted by the shifting sensor 11, and controls the shifting actuator to perform a shifting operation matching the current required gear. Therefore, the electronic shifting unit can quickly respond to the driver's shifting command and reduce the complex mechanical components in the traditional pure mechanical shifting system.

[0055] In some embodiments, the shift sensor 11 may include a Hall sensor, a photoelectric sensor, a position sensor or a magnetic sensor to detect the position of the shift lever 3 at different required gears. In some embodiments, the shift actuator may be a transmission gear actuator. In some embodiments, the shift receiver may be an ECU (Electronic Control Unit). In some embodiments, the shift receiver is a TCU (Transmission Control Unit), and the shift receiver is embedded and integrated in the TCU.

[0056] In this way, the embodiment of the present application selects the gear position through the mechanical gear selection part, and at the same time uses the electronic gear shift part to improve the intelligence and functionality of the gear shift, so as to achieve a faster and more accurate gear shift operation, while maintaining the intuitiveness and gear shift feel of the mechanical gear shift. The fixed rotating hub 31 is used to transmit the movement of the gear selection handle 3 to the gear shift sensor 11 on the required gear position. Compared with the traditional connecting rod, gear meshing structure or other transmission devices, the fixed rotating hub 31 has a simple structure and a small size, which not only allows the gear selection handle 3 to have more degrees of freedom, but also reduces the number of parts, reduces the failure rate, and improves the service life performance of the gear shifter. The mechanical gear selection part composed of the fixed rotating hub 31 and the gear selection handle 3 is compact and easy to arrange. When designing the auxiliary instrument panel, there is no need to design and adjust the instrument panel specifically to adapt to the installation of the mechanical gear selection part, and space is reserved for the layout of other functions of the instrument panel. In the limited auxiliary instrument panel space, it is easier to arrange the whole vehicle, shorten the design cycle, and save development costs.

[0057] As a further improvement of this embodiment, the electronic shift unit also includes multiple shift indicator lights 5 , each of the shift sensors 11 is a Bluetooth sensor, and the multiple Bluetooth sensors are wirelessly connected to the shift receiver and wirelessly connected to the multiple shift indicator lights 5 .

[0058] In this embodiment, the shift sensor 11 using Bluetooth technology for signal transmission communicates with the shift receiver via Bluetooth, and outputs a single fixed frequency to the vehicle through the Bluetooth transmitter to achieve differentiation of different gear signals corresponding to each required gear. The shift receiver transmits the corresponding gear signal to the TCU based on the difference in the received gear signal, thereby achieving gear switching. This device changes the existing signal transmission method of connecting the CAN network through hard wires. The Bluetooth sensor also communicates with the shift indicator light 5. Each shift indicator light 5 is equipped with a Bluetooth receiving module, which can receive the sensor signal to indicate the current gear selection state.

[0059] Specifically, the gear shift mechanism is provided with a plurality of required gears. The Bluetooth sensor can detect the current position of the gear selector 3 and transmit the information to the gear shift indicator 5 and the gear shift receiver respectively. The gear shift indicator 5 indicates the gear status in real time according to the received gear signal. The gear shift receiver generates corresponding control instructions according to different gear signals and sends them to the actuator corresponding to the transmission. Each required gear corresponds to an electric actuator, which drives it to complete the gear shift operation.

[0060] For example, see Figure 6 and Figure 7 , Figure 6 The overall structure diagram of the shift indicator light 5 of the present application is shown; Figure 7The overall structural diagram of the shift sensor 11 of the present application is shown. Five required gears are set on the gear switching mechanism, such as P gear position, M gear position, R gear position, N gear position, and D gear position, and all five positions are marked. Five Bluetooth sensors with different frequencies are used for the gear signal transmitters of P\R\N\D\M, which are placed on the five required gears respectively. By moving the gear selector handle 3 to different positions, the Bluetooth sensor senses the gear selector handle 3 at the corresponding position, thereby realizing gear shifting. Each gear shift indicator light 5 is installed on the gear shift housing. The specific operation method is:

[0061] A P gear Bluetooth sensor 115 is provided at the P gear position, and the P gear Bluetooth sensor 115 communicates with the P gear indicator light;

[0062] An M-gear Bluetooth sensor 113 is provided at the M-gear position, and the M-gear Bluetooth sensor 113 communicates with the M-gear indicator light 53;

[0063] An R gear Bluetooth sensor 112 is provided at the R gear position, and the R gear Bluetooth sensor 112 communicates with the R gear indicator light;

[0064] An N gear Bluetooth sensor 114 is provided at the N gear position, and the N gear Bluetooth sensor 114 communicates with the N gear indicator light;

[0065] A D gear Bluetooth sensor 111 is provided at the D gear position, and the D gear Bluetooth sensor 111 communicates with the D gear indicator light 54 .

[0066] like Fig.11 The shift device and the shift actuator provided in the embodiment of the present application together constitute the shift assembly, and the two exchange information through the TCU, and the P gear Bluetooth sensor 115, the M gear Bluetooth sensor 113, the N gear Bluetooth sensor 114, the D gear Bluetooth sensor 111, and the R gear Bluetooth sensor 112 in the shift device are all connected to the TCU, and the TCU is connected to the transmission P gear actuator, the transmission M gear actuator, the transmission N gear actuator, the transmission D gear actuator, and the transmission R gear actuator.

[0067] In the actual shifting process, when the driver operates the shift lever 3 and moves it to the D gear position, the Bluetooth sensor detects the D gear position and sends a signal to the TCU and the D gear indicator 54, lighting up the D gear indicator 54 on the shift housing. At the same time, the TCU sends the corresponding control command to the transmission D gear actuator according to the D gear signal, and the transmission D gear actuator receives the command and drives the transmission to switch to the D gear, completing the shifting operation.

[0068] Similarly, when you need to switch to other gear positions, the operation is the same.

[0069] In some embodiments, there is no one-to-one correspondence between the number of gear shift indicator lights 5 and the number of gear shift sensors 11. In particular, no P gear indicator light may be provided, and the P gear Bluetooth sensor 115 does not communicate with any gear shift indicator light 5. When no indicator light is on during vehicle driving, it indicates that the current gear is P gear.

[0070] Preferably, the P gear Bluetooth sensor 115 is placed separately in the middle position of the gear shifter.

[0071] In some optional embodiments, the shift indicator light 5 may also be connected to the TCU, and the TCU controls the corresponding shift indicator light 5 to light up according to the received gear position signal, and simultaneously drives the shift actuator to operate.

[0072] Therefore, this application innovatively uses Bluetooth signals as a way to transmit gear signals, cancels the traditional signal transmission method of connecting the CAN network through hard wires, and receives the corresponding gear signals through the TCU embedded receiver. It simplifies the wiring, reduces the wiring harness layout inside the vehicle, simplifies the wiring harness architecture, reduces the equipment failure rate, and improves the simplicity, aesthetics and reliability of the overall design.

[0073] As a further improvement of this embodiment, each of the shift sensors 11 is a magnetic sensor; wherein the shift handle 3 is made of magnetic material. In this embodiment, the shift handle 3 approaches the magnetic sensor at the corresponding gear position during the gear shift process, and the magnetic sensor detects the change in the magnetic field and sends a signal to the shift receiver. No physical contact is required, mechanical wear is avoided, and the service life is extended.

[0074] In combination with the above embodiments, the embodiments of the present application use Bluetooth signals as a carrier to transmit shift signals, and cooperate with magnetic sensors to achieve accurate gear detection and shift operations. The wear and failure of traditional mechanical contact sensors are avoided, and the reliability and life of the shift device are improved. Therefore, the P gear Bluetooth sensor 115, the M gear Bluetooth sensor 113, the N gear Bluetooth sensor 114, the D gear Bluetooth sensor 111, and the R gear Bluetooth sensor 112 all correspond to the P gear magnetic Bluetooth sensor, the M gear magnetic Bluetooth sensor, the N gear magnetic Bluetooth sensor, the D gear magnetic Bluetooth sensor, and the R gear magnetic Bluetooth sensor.

[0075] In a further technical solution, the gear selection handle 3 includes an operating lever 32 and a driven lever 33; wherein the fixed rotating hub 31 is connected to the gear shift housing; the operating lever 32, the fixed rotating hub 31 and the driven lever 33 are connected in sequence, and the operating lever 32 drives the driven lever 33 to move through the fixed rotating hub 31 and pass through the gear switching mechanism.

[0076] In this embodiment, the fixed rotating hub 31 divides the gear selector handle 3 into two parts, namely, the upper part of the operating lever 32 and the lower part of the driven lever 33. The operating lever 32 is the part directly operated by the driver, and the driven lever 33 moves with the operating lever 32 and contacts the gear shift sensor 11. The fixed rotating hub 31 is fixed to the gear shift housing through a cover plate, so that the gear selector handle 3 is fixed to the gear shift housing but can be freely switched in the gear shift housing.

[0077] The joystick 32, the fixed rotating hub 31 and the driven rod 33 are connected in a certain order to form a mechanical chain. The user operates the joystick 32, and the force is transmitted to the driven rod 33 through the fixed rotating hub 31, so that the driven rod 33 is linked with the joystick 32 through the fixed rotating hub 31, and the driven rod 33 moves between the required gears to achieve gear switching.

[0078] In combination with the above embodiments, the driven rod 33 of the gear selection handle 3 is made of magnetic material to cooperate with the magnetic sensor.

[0079] In this embodiment, the operating lever 32, the fixed rotating hub 31 and the driven lever 33 can be integrally formed, that is, the middle and lower regions of the straight rod are protruded outward to form the fixed rotating hub 31, and the inner diameters of the remaining portions are the same to form the ball-jointed gear selection handle 3. In some embodiments, the operating lever 32, the fixed rotating hub 31 and the driven lever 33 can be assembled into an integral part.

[0080] Specifically, the fixed rotating hinge 31 is a ball-joint structure; the joystick 32 extends out of the shift housing, and a shift hand ball 4 is provided at the end of the extended part. In this embodiment, the middle and lower part of the ball-joint gear selection handle 3 protrudes outward in a spherical structure to form a spherical hinge, and the joystick 32 can move freely in multiple directions around the center point of the ball-joint structure. The shape and contour of the ball-joint structure limit the movement range and direction of the joystick 32 and the driven rod 33, forming an arc-shaped motion trajectory. The motion trajectory of the driven rod 33 is opposite to that of the joystick 32. The joystick 32 and the driven rod 33 move synchronously in an inclined straight line in the gear switching mechanism. The hand ball 4 installed at the end of the joystick 32 serves as a spherical grip, and the driver selects different required gears by pushing and pulling the hand ball 4.

[0081] See also Figure 4 and Figure 5 , Figure 4 A schematic diagram of the three-dimensional structure of the end cover 1 provided with an active limiting slideway 17 of the present application is shown; Figure 5 It is an overall schematic diagram of the driven limiting slideway 12.

[0082] As a specific explanation of this embodiment, the gear switching mechanism includes an active limit slide 17 and a driven limit slide 12, the active limit slide 17 matches the moving path of the operating rod 32, and the driven limit slide 12 matches the moving path of the driven rod 33; wherein the active limit slide 17 and the driven limit slide 12 are radially symmetrically arranged, and the outer edge contour is an arc.

[0083] Specifically, the active limit slide 17 guides the movement path of the operating lever 32. When the operating lever 32 is shifting, it will move along the contour of the active limit slide 17 and limit the operating lever to stop at each preset required gear position; the driven limit slide 12 guides the movement path of the driven rod 33. During the gear shifting process, the driven rod 33 will move along the contour of the driven limit slide 12, and synchronously limit the driven rod 33 to stop at each preset required gear position, and use the slide groove of its own limit slide to fix the entire gear selection handle 3.

[0084] Therefore, when the ball-jointed gear selector handle 3 is operated to select gears, the active limit slide 17 and the driven limit slide 12 are radially symmetrically arranged to match the rotation path of the spherical rotation center of the ball-jointed structure, so that the operating rod 32 and the driven rod 33 in the two limit slides can slide smoothly along their respective corresponding limit slides when they move synchronously in opposite directions.

[0085] Among them, the arc-shaped limit slide provides a continuous path, reduces friction and sticking at right-angle turns, and conforms to the movement trajectory of the rotation center of the ball joint structure, ensuring that when the joystick 32 drives the driven rod 33 to move synchronously through the ball joint structure, the path of the limit slide is completely consistent with its movement trajectory.

[0086] In a further technical solution, the active limit slide 17 and the driven limit slide 12 both include a plurality of sub-slides interconnected with each other, each sub-slide corresponding to each required gear position; each shift sensor 11 is arranged one-to-one on each sub-slide in the driven limit slide 12.

[0087] Specifically, the limit slide ensures the accurate positioning of the gear selection handle 3 between different required gears, and controls the movement range of the handle together with the fixed rotating hub 31. Corresponding gear marks are respectively set on the multiple sub-slides on the active limit slide 17. Each shift sensor 11 corresponds to a sub-slide in the driven limit slide 12, and the positions of the sub-slides on the active limit slide 17 and the sub-slides on the driven limit slide 12 also correspond to each other. Therefore, the required gear can be calibrated by text in the active limit slide 17 through which the joystick 32 passes, so that the driver can directly identify and operate it. Since the driven lever 33 is related to the movement trajectory of the joystick 32, the frequency of the shift sensor 11 on the different required gears on the driven limit slide 12 matches the calibration serial number of the required gear one by one, and the shift receiver receives the gear signal carrying the frequency mark transmitted from the shift sensor 11 on the corresponding required gear, and the current required gear can be determined.

[0088] In the present application, the number and position of the sub-slides on the active limit slide 17 and the driven limit slide 12 can be determined according to the number of gears actually required, for example, two gears, three gears, four gears or five gears can be set, and different shapes of continuous connection can be formed. As an example, two gears can be set, and the two sub-slides can be arranged in a horizontal, vertical or inclined straight line; or one sub-slide can be horizontal and the other can be vertical, forming an L-shaped layout; and a shift sensor 11 is set at the edge of each straight line segment. As an example, four gears can be set, and the four sub-slides can form a cross shape, and a shift sensor 11 is set at each end point.

[0089] Preferably, five required gears are provided to realize the switching of the five gears of P, R, N, D, and M. The five sub-slideways on the active limit slideway 17 form a hollow I-shaped protrusion outward, and the gear selection handle 3 passes through the center of the I-shaped shape and reciprocates in the five sub-slideways. When the driver pushes the joystick 32 to move, the driven rod 33 located below the spherical hub moves in the opposite direction. When it moves to the selected gear, the end of the driven rod 33 just enters the corresponding sub-slideway corresponding to the selected gear, close to the gear shift sensor 11, so that the gear selection handle is fixed;

[0090] like Figure 8 and Fig. 9 As shown, Figure 8 It is a schematic structural diagram of the shift indicator light 5 when assembled on the end cover 1. Fig. 9 It is a state diagram of the gear selection handle 3 when switching between required gears. For example, in a specific implementation:

[0091] Move the gear selector 3 downward to the right to the edge of the right lower slideway, and then switch to D gear;

[0092] Move the gear selector 3 downward to the left to the edge of the left lower slideway, and then switch to M gear;

[0093] Move the gear selector handle 3 to the upper right to the edge of the upper right slideway, and then switch to the R gear;

[0094] Move the gear selector handle 3 to the upper left to the edge of the upper left slideway, and then switch to N gear;

[0095] The gear selector handle 3 is in the middle position, and the gear is switched to P.

[0096] In this embodiment, since the electronic shifter has no physical connection, it is difficult for the driver to immediately perceive the shifting action, and the driver needs to confirm whether the gear position is correct by vision or other means. However, a driven limit slide 12 is used, and a plurality of sub-slides corresponding to the gear positions are arranged in the driven limit slide 12. A limit structure is arranged in the sub-slide, such as a slot corresponding to the position of the required gear position, etc. When the driven rod 33 moves to a certain gear position, its end edge is stuck in the slot in the sub-slide, providing a clear gear position feeling.

[0097] As a further improvement of this embodiment, a sliding mechanism is provided at the position where the driven rod 33 contacts the sub-slideway, and the sliding mechanism includes a ball 10, a limit block 9 and a mounting nut 8; the ball 10 is movably arranged in the driven rod 33 through the mounting nut 8, and at least part of the ball 10 protrudes from the driven rod 33; wherein,

[0098] The limiting block 9 is sleeved on the outer circumference of the ball 10 located in the driven rod 33 .

[0099] In this embodiment, a portion of the sliding ball is fastened in the driven rod 33 by the mounting nut 8, but the sliding ball is allowed to rotate within a certain range, and a portion of the ball 10 is embedded in the driven rod 33, and a portion protrudes outside, and is movably embedded in the sub-slide of the driven limit slide 12 through the protruding portion.

[0100] Therefore, when the gear selection handle 3 switches between the required gears, the ball 10 rolls or slides, so that the gear selection handle 3 has a smooth feel during the gear switching process. Therefore, the ball-hinged gear selection handle 3 is combined with the ball 10 limiting structure, and the ball 10 is installed at the bottom of the gear selection handle 3. Under the condition of the ball 10, the active limiting slide 17 and the driven limiting slide 12 jointly limiting, the five gears of P, R, N, D and M are switched. This structure has smooth gear shifting, convenient maintenance, modular components, and solves the current problems of gear shifting stagnation and uneven gear shifting.

[0101] Furthermore, a limit block 9 is provided between the ball 10 and the driven rod 33. The limit block 9 may be a limit ring, which matches the outer edge profile of the ball 10 and is just sleeved in the rotation gap between the ball 10 and the driven rod 33. Specifically, the limit block 9 is made of nylon material and is soaked with lubricating oil. Therefore, the nylon material itself has a certain lubricity. The ball 10 is wrapped by the impregnation of lubricating oil, which not only restricts the rotation space of the ball 10, but also makes the ball 10 move according to the contour trajectory of the driven limit slide 12; at the same time, it ensures the mechanical wear of the gear selector handle 3 during movement. The ball twist structure and the design of the ball 10 make the gear shifting process smoother and reduce the uneven phenomenon.

[0102] In combination with the above embodiments, the ball 10 is installed on the driven rod 33 of the ball-twisted gear selection handle 3 through the cooperation of the mounting nut 8 and the limit block 9. When the gear selection handle 3 moves, the ball 10 fixed under the driven rod 33 moves in the opposite direction; when the joystick 32 moves to the corresponding gear position, the ball 10 just enters the limit structure of the driven limit slide 12, so that the gear selection handle 3 is fixed; and then the shifting action of the shifter is realized through the cooperation of the active limit slide 17 and the driven limit slide 12. At the same time, the Bluetooth sensor installed on the driven limit slide 12 sends a shift signal to the shift receiver, thereby realizing the gear switching. At the same time, the shift indicator 5 synchronously displays the corresponding gear position.

[0103] In combination with the above embodiments, when the gear shift sensor 11 is a magnetic sensor, the ball 10 and the mounting nut 8 are made of magnetic material, so that they can be detected by the magnetic sensor when they move to each gear position. The magnetic ball 10 and the magnetic mounting nut 8 are integrated into one body, and roll together in the driven limit slide 12 to be closer to the position of the magnetic sensor set on the driven limit slide 12.

[0104] In this embodiment, the material of the gear selector handle 3 may be a magnetic material or a non-magnetic material.

[0105] Please refer to Figure 3 , Figure 4 and Fig.10 As shown, Figure 3 A schematic diagram of the three-dimensional structure of the base 2 of the present application is shown; Fig.10The side cross-sectional view of the shift indicator light 5 and the bolt 18 of the present application is shown. In another technical solution, the shift housing includes an end cover 1 and a base 2, the active limit slide 17 is arranged on the end cover 1, and the driven limit slide 12 is arranged on the bottom wall surface of the base 2; wherein the end cover 1 and the base 2 are connected by a plurality of bolts 18, and at least some of the bolts 18 have different heights. In this embodiment, the end cover 1 is located at the top part of the shift housing, and the base 2 is the bottom part of the shift housing, and the two are connected by a plurality of bolts 18, so the split design facilitates assembly and maintenance.

[0106] In combination with the above embodiments, an I-shaped active limit slide 17 is arranged on the end cover 1. In this way, an installation space for the active limit slide 17 can be reserved on the rectangular end cover 1, and the prepared active limit slide 17 is welded to the installation space. Or in another way, a hole is directly opened on the end cover 1 to form a functional end cover 1 with a limit slide. Similarly, a driven limit slide 12 is arranged on the bottom wall surface of the base 2 for the driven rod 33 to move. In this way, the prepared driven limit slide 12 can be pasted to the bottom wall surface of the base 2, wherein the shape contour of the bottom wall surface should be an arc-shaped wall surface to fit with the driven limit slide 12, so that when the driven limit slide 12 is mounted on the base 2, the ball 10 on the driven rod 33 is located in the driven limit slide 12 and is in rolling contact with the bottom wall surface of the base 2. Or in another embodiment, a plurality of holes, namely slideways, are directly opened on the arc-shaped bottom wall surface of the base 2 to form a driven limit slideway 12 .

[0107] In some embodiments, when the driven limit slide 12 is attached to the base 2, a shift sensor installation point 16 is opened on the base 2, and the shift sensor 11 can be set in the shift sensor installation point 16 on the base 2. The installation position is located in each sub-slide of the driven limit slide 12, and the D gear magnetic Bluetooth sensor, R gear magnetic Bluetooth sensor, M gear magnetic Bluetooth sensor and N gear magnetic Bluetooth sensor are correspondingly installed in the shift sensor installation point 16.

[0108] For example, a cavity is formed inside the top opening of the base 2, and four lifting ears are arranged outside the top opening, which are symmetrically arranged on the top outside of the base 2, and each lifting ear has a base mounting hole 15 for mounting on the auxiliary instrument. Two blind holes are respectively arranged on the opposite sides of the inner side of the top opening, and two screw holes are respectively arranged on the opposite edges of the end cover 1. The screw holes are opposite to the blind holes, and four bolts 18 are passed through the screw holes to connect with the blind holes, so that the end cover 1 and the base 2 are installed together.

[0109] In this embodiment, the heights of the four bolts 18 can be different, and the base 2 can achieve the installation limit of the cover plate by limiting the position of three high and one low. Of course, the heights of the four bolts 18 can be two high and two low, one high and three low, etc. In some embodiments, the heights of the edge portions of the base 2 where the four bolts 18 are installed are different.

[0110] Among them, the shift indicator light 5 is integrated on the bolt 18, and the shift indicator light installation point 13 is set inside the screw hole for the installation of the end cover 1 and the base 2. The N gear indicator light 51, the R gear indicator light 52, the M gear indicator light 53 and the D gear indicator light 54 are set on the four bolts 18 in a one-to-one correspondence.

[0111] In combination with the above embodiments, in a specific implementation scheme, a mechanical gear selection type electronic shift device is composed of a hand ball 4, a base 2, an end cover 1 with an active limit slide 17, a ball-twisted gear selection handle 3, a gear shift indicator light 5, an upper cover plate 6, a lower cover plate 7, a limit block 9, a magnetic ball, a magnetic ball mounting nut 8, a magnetic Bluetooth sensor, a driven limit slide 12, etc. The overall structure is simple, the layout is compact, and the installation and disassembly are convenient and convenient for after-sales maintenance. The gear shift indicator light 5 is integrated on the bolt 18 for the installation of the end cover 1 and the base 2. The ball-twisted connection structure is used, and it is connected to the base 2 through the driven limit slide 12, so that the gear selection handle 3 has more degrees of freedom. The gear selection handle 3 reaches the corresponding gear position through the joint action of the end cover 1 and the driven limit slide 12. The limit slide also plays the role of fixing the gear selection handle 3 at the position of the corresponding gear position, thereby improving the gear shift perception. The ball-twist type gear selector handle 3 cooperates with the handball 4 and is integrated into the vehicle to better reflect the vehicle's sense of technology and youthfulness. Among the existing electronic gear shifter products, the method is novel and can effectively improve the brand recognition; the gear shifting operation is simpler and more reasonable, which can effectively avoid misoperation.
