[0074] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0075] The terms "first", "second", "third", "fourth" and the like in the description and claims of the present application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

[0076] As shown in Figure 1 and Figure 2 , the present application provides a sliding electronic gear shifter, which comprises a control mechanism 9 and a gear shifting mechanism 8 connected with the control mechanism 9, the gear shifting mechanism 8 comprises a gear shifter housing 80 and a slider body 81 arranged in the gear shifter housing 80, the slider body 81 is connected with the control mechanism 9 and can slide relative to the gear shifter housing 80 under the driving of the control mechanism 9. The bottom of the slider body 81 is provided with a plurality of groups of sliding sheets located at different positions, and a gear shifter circuit board 1 is arranged below the sliding sheets, the gear shifter circuit board 1 is provided with a plurality of groups of copper clad sheets corresponding to the sliding sheets, when the slider body 81 slides along the gear shifter housing 80 to different positions, different groups of sliding sheets are in contact with corresponding copper clad sheets to form different conduction loops, thereby realizing the switching of different gears.

[0077] Specifically, please refer to Figure 3 , the slider body 81 is a columnar body with an octagonal cross section, the top end of the middle part of the slider body 81 is provided with a first control member connector 811 protruding out of the slider body 81, and the slider body 81 is connected with the control mechanism 9 through the first control member connector 811. The inside of the first control member connector 811 is provided with a connector terminal 812 protruding out of the corresponding surface of the first control member connector 811, so that the first control member connector 811 is formed into a connector male end, and the connector terminal 812 is connected with a wire 7 embedded in the inside of the slider body 81, the wire 7 extends downward from the top of the slider body 81 to the bottom of the slider body 81 and is connected with the sliding sheet signal at the bottom of the slider body 81. The shape of the first control member connector 811 has a foolproof design, and the cross section of the first control member connector 811 is generally in the shape of "concave" in this embodiment, so that the first control member connector 811 is formed into a first foolproof connector, and the control mechanism 9 is provided with a second foolproof connector corresponding to the first foolproof connector, the side surfaces of the first foolproof connector and the second foolproof connector are provided with fixing holes 816, and the slider body 81 is connected with the control mechanism 9 through the plug-in cooperation of the first foolproof connector and the second foolproof connector and the insertion of a fixing member 817 into the fixing holes 816. The periphery of the first control member connector 811 is further provided with a buffer pad 818, which is arranged between the first control member connector 811 and a connecting column through hole 831 (see Figure 5 ) arranged on the gear shifter housing 80, so as to reduce the vibration and friction generated during the sliding of the slider body 81.

[0078] The middle part of the slider body 81 is provided with a plurality of inclined first friction surfaces 815, which are distributed at the corner positions of the upper two sides and the lower two sides of the slider body 81 along the circumferential direction of the slider body 81. The gear shifter housing 80 includes a gear shifter upper housing 83 and a gear shifter lower housing 84. As shown in Figure 8 , the gear shifter upper housing 83 and the gear shifter lower housing 84 are provided with a plurality of second friction surfaces 836, which are distributed inside the gear shifter upper housing 83 and the gear shifter lower housing 84. The second friction surfaces 836 and the first friction surfaces 815 form a friction pair, and the second friction surfaces 836 are in contact with the first friction surfaces 815 during the sliding process of the slider body 81 relative to the gear shifter housing 80. It should be noted that there is a sufficient gap between the second friction surfaces 836 and the first friction surfaces 815, and grease is applied in this gap to ensure the smoothness of the operation feel.

[0079] Please refer to Figure 4 and Figure 9 , the two ends of the slider body 81 are provided with sliding bushings 82, which are made of wear-resistant engineering plastics (such as POM, PA, etc.), and the cross section is also octagonal. The sliding bushings 82 are fixed to the slider body 81 through the cooperation between the positioning recesses 814 provided on the upper and lower four surfaces of the slider body 81 and the positioning protrusions 822 provided at the corresponding positions of the sliding bushings 82. It can be understood that the positions of the positioning recesses 814 and the positioning protrusions 822 can be interchanged to achieve the same effect of fixing the sliding bushings 82. The corner positions of the upper two sides and the lower two sides of the sliding bushings 82 are provided with a plurality of elastic contacts 821 that can expand outward or contract inward, and the elastic contacts 821 are located between adjacent positioning protrusions 822, and the elastic contacts 821 are provided with protrusions that are in line contact with the gear shifter housing 80, which can reduce the contact area between the elastic contacts 821 and the gear shifter housing 80. The positions corresponding to the elastic contacts 821 at both ends of the slider body 81 are provided with contact deformation grooves 813, and the elastic contacts 821 move along the depth direction of the contact deformation grooves 813 during the expansion or contraction process. Please refer to Figure 6 and Figure 10The two ends of the gear shifter housing 80 are provided with gear sensing grooves 841 into which the elastic contacts 821 extend. The middle part of the gear sensing groove 841 is inwardly recessed, and includes a first inclined surface 841a extending from the middle part of the gear sensing groove 841 to the middle part of the gear shifter housing 80 and a second inclined surface 841b extending from the middle part of the gear sensing groove 841 to the two ends of the gear shifter housing 80, the inclination angle of the first inclined surface 841a is smaller than that of the second inclined surface 841b, so that the height difference of the two ends of the gear sensing groove 841 is different. When the slider body 81 slides forward, the elastic contact 821 on the front end sliding bushing 82 contacts the second inclined surface 841b of the corresponding gear sensing groove 841, and the elastic contact 821 on the rear end sliding bushing 82 contacts the first inclined surface 841a of the corresponding gear sensing groove 841. Due to the different inclination angles of the first inclined surface 841a and the second inclined surface 841b, the height difference of the two is different, the deformation amount of the elastic contact 821 contacting the second inclined surface 841b is greater than that of the elastic contact 821 contacting the first inclined surface 841a, the elastic contacts 821 at the front and rear ends of the two slider bodies 81 will generate a return force opposite to the movement direction of the slider body 81, and when moving forward, the return force of the front end sliding bushing 82 is greater than that of the rear end sliding bushing 82. When the operating mechanism 9 is released, the return force of the sliding bushing 82 will push the slider body 81 back to the stable position in the middle of the gear shifter, realizing the self-resetting function. In addition, by providing the elastic contact 821 on the sliding bushing 82, linear contact between the sliding bushing 82 and the gear shifter housing 80 can be formed, the contact area is reduced, the smoothness of the sliding of the slider body 81 is increased, and the setting of the elastic contact 821 can eliminate the weak gap between the four sliding friction pairs formed by the first friction surface 815 and the second friction surface 836, so that the slider body 81 will not shake due to the gap during sliding. Moreover, due to the symmetrical distribution of the elastic contacts 821 on the upper and lower left and right of the sliding bushing 82, the elastic force generated by the elastic contacts 821 can be internally balanced and not output externally, so that the sliding process of the slider body 81 can ensure smooth operation, no virtual position and excellent thick feeling.

[0080] Please refer to Figures 5 to 7The lower shell 84 of the gear shifter is provided with four self-tapping screw holes 843, and the upper shell 83 of the gear shifter is provided with four screw holes 833. The upper shell 83 and the lower shell 84 of the gear shifter are connected together by self-tapping screws inserted into the screw holes 833 and the self-tapping screw holes 843. In addition, the middle of the long side of the lower shell 84 is provided with front and rear positioning blocks 844, and the middle of the short side of the lower shell 84 is provided with left and right positioning blocks 845. The middle of the long side of the upper shell 83 is provided with front and rear positioning recesses 834, and the middle of the short side of the upper shell 83 is provided with left and right positioning recesses 835. When the upper shell 83 and the lower shell 84 of the gear shifter are connected, the front and rear positioning blocks 844 are clamped in the front and rear positioning recesses 834, and the left and right positioning blocks 845 are clamped in the left and right positioning recesses 835, further preventing the upper shell 83 and the lower shell 84 of the gear shifter from sliding relative to each other in the left-right and front-rear directions. In addition, the four corners of the outside of the lower shell 84 are also provided with assembly mounting holes 846, and bushings 847 are mounted in the assembly mounting holes 846.

The deformation groove 62 is arranged along the length direction of the sliding piece, used for eliminating the stress of the sliding piece and increasing the elasticity of the sliding piece. The noble metal contact 63 is used for increasing the wear resistance and electrode oxidation resistance of the sliding piece.

[0083] As shown in Figure 14As shown, the shifter circuit board 1 is arranged on the circuit board support 85, and the circuit board support 85 is fixed below the slide support 86 by bolts penetrating the circuit board support 85, the shifter circuit board 1, and the stud in the bottom of the shifter lower shell 83.

[0084] Please refer to Figures 12 to 15 The slides include a first slide group 6, a second slide group 4, a third slide group 5, and a fourth slide group 3. The first slide group 6, the second slide group 4, and the third slide group 5 are arranged in a line along the length direction of the slide support 86, and the second slide group 4 and the third slide group 5 are respectively located on the front and back sides of the first slide group 6. The fourth slide group 3 is arranged along the width direction of the slide support 86 with the noble metal contact 63 of the first slide group 6. The copper-clad pieces include a first copper-clad piece group 15, a second copper-clad piece group 13, a third copper-clad piece group 14, and a fourth copper-clad piece group 12.

[0085] Please refer to Figure 16, each of the copper foil groups comprises a first copper foil, a second copper foil, a third copper foil and a fourth copper foil arranged in a row along the width direction of the gear shifter circuit board 1, and the first copper foil, the second copper foil, the third copper foil and the fourth copper foil of each of the copper foil groups are arranged outward from the middle part of the gear shifter circuit board 1. For the convenience of distinction, the first to fourth copper foils of the first copper foil group 15 are respectively marked as O-1, O-2, O-3 and O-4, the first to fourth copper foils of the second copper foil group 13 are respectively marked as F1-1, F1-2, F1-3 and F1-4, the first to fourth copper foils of the third copper foil group 14 are respectively marked as R1-1, R1-2, R1-3 and R1-4, and the first to fourth copper foils of the fourth copper foil group 12 are respectively marked as GND, VBAT, LIN-out and LIN-in. The lengths of the four copper foils of the first copper foil group 15 are equal, all being L1, the lengths L3 of the first copper foils F1-1 and R1-1 and the third copper foils F1-3 and R1-3 of the second copper foil group 13 and the third copper foil group 14 are not equal to the lengths L2 of the second copper foils F1-2 and R1-2 and the fourth copper foils F1-4 and R1-4, in this embodiment, the lengths L3 of the first copper foils F1-1 and R1-1 and the third copper foils F1-3 and R1-3 of the second copper foil group 13 and the third copper foil group 14 are half of the lengths L2 of the second copper foils F1-2 and R1-2 and the fourth copper foils F1-4 and R1-4. The purpose of such arrangement is to reduce the frequency of the on-off jump of the switch signal at the moment when the two sliders simultaneously contact the corresponding copper foils, and to facilitate the adjustment of the accuracy of the shift lever.

[0086] Further, the fourth copper foil group 12 further comprises a fifth copper foil P-SW, the fifth copper foil P-SW is located between the first copper foil GND of the fourth copper foil group 12 and the first copper foil O-1 of the first copper foil group 15, and the length of the fifth copper foil P-SW of the fourth copper foil group 12 is equal to the length L1 of each copper foil in the first copper foil group 15, the lengths L4 of the first to fourth copper foils GND, VBAT, LIN-out and LIN-in of the fourth copper foil group 12 are 3 times the length L1 of the fifth copper foil P-SW, the lengths of the first to fourth copper foils GND, VBAT, LIN-out and LIN-in of the fourth copper foil group 12 are longer, covering the entire movement range of the slider body 81, so that the corresponding circuits of the first to fourth copper foils GND, VBAT, LIN-out and LIN-in of the fourth copper foil group 12 are in the conducting state during the movement of the slider body 81. The length of the fifth copper foil P-SW of the fourth copper foil group 12 is relatively short, which is mainly to shield the operation of the P gear button during the operation of the gear shifting (i.e. even if the operation, no signal is transmitted).

[0087] As Figure 15As shown, the first slider group 6, the second slider group 4, the third slider group 5 and the fourth slider group 3 each include first sliders, second sliders, third sliders and fourth sliders arranged in a row along the width direction of the slider support 86, the first sliders, the second sliders, the third sliders and the fourth sliders of each slider group are arranged outward from the middle part of the slider support 86, and the fourth slider group 3 further includes a fifth slider located between the first slider of the first slider group 6 and the first slider of the fourth slider group 3. The noble metal contacts 63 at the bottom ends of the sliders in each slider group are arranged in a row along the width direction of the slider support 86, so as to be capable of being in contact with the corresponding copper-clad sheets simultaneously during the sliding of the slider body 81.

[0088] As shown, Figure 17 The sliding electronic gear shifter of the present application has three working positions, namely the steady position (O position), the F1 position and the R1 position. When not operated, the slider body 81 is located at the steady position, and the slider body 81 can be moved forward to reach the F1 position or moved backward to reach the R1 position. When gear shifting is needed, the operating mechanism 9 is operated once to reach the F1 position or the R1 position, and a gear shifting request is sent once. For example, if the current gear position is N, the slider body 81 is moved forward to the F1 position to change to R, and the slider body 81 is moved backward to the R1 position to change to D; if the current gear position is D, the slider body 81 is moved forward to the F1 position to change to N, and the slider body 81 is moved backward to the R1 position, and the gear position remains unchanged. If it is desired to change from D to R, the slider body 81 needs to be moved to the F1 position twice or kept at the F1 position for more than 2 seconds. The specific control strategy can be specified according to requirements, and the present application will not be described in detail.

[0089] During the movement of the slider body 81, when the slider body 81 is located at the steady position (O position) in the middle of the shifter housing 80 or within a certain range near the steady position, the sliders of the first slider group 6 are in contact with the copper-clad sheets of the first copper-clad sheet group 15, and are connected with the I / O port of the MCU through the internal circuit of the shifter circuit board 1, so that the interval sliders of the first slider group 6 and the corresponding copper-clad sheets (for example, O-1 and O-3, O-2 and O-4) of the first copper-clad sheet group 15 form a path; when the slider body 81 is slid forward and leaves the steady position area, the sliders of the first slider group 6 are no longer in contact with the copper-clad sheets of the first copper-clad sheet group 15, and the path is disconnected. The whole process is like a normally closed switch, when the operating mechanism 9 is not operated, the slider body 81 is located at the steady position, the switch is closed, otherwise it is disconnected;

[0090] When the slider body 81 slides forward into the F1 position area (or slides backward into the R1 position area), the slide of the second slide group 4 (or the third slide group 5) contacts the copper clad of the second copper clad group 13 (or the third copper clad group 14), forming a path between the gear shifter circuit board 1 and the MCU, but the position of the slide forming the path is different from the position of the slider body 81 in the steady state position. When the slider body 81 is in the F1 or R1 position area, the adjacent slide of the second slide group 4 (or the third slide group 5) forms a path with the corresponding copper clad of the second copper clad group 13 (or the third copper clad group 14). It can be understood that in other embodiments of the present application, the conductive position of the slide and the copper clad can also be designed in other ways, for example, when the slider body 81 is located in the middle of the gear shifter housing 80, the adjacent slide of the first slide group 6 forms a path with the corresponding copper clad O-1, O-2 of the first copper clad group 15, when the slider body 81 slides forward, the interval slide of the second slide group 4 forms a path with the corresponding copper clad of the second copper clad group 13, and when the slider body 81 slides backward, the interval slide of the third slide group 5 forms a path with the corresponding copper clad of the third copper clad group 14.

[0091] It should be noted that the paths formed by the first copper clad group 15, the second copper clad group 13 and the third copper clad group 14 in the present application are designed as two paths, which is to realize the limp function, when one path fails, the system reports a fault, but the other path can support normal operation, improve the safety level of the whole system. The second slide group 4 (or the third slide group 5) is designed differently from the first slide group 6, which is to prevent the second slide group 4 (or the third slide group 5) from moving to the O position when the slider body 81 moves to the F1 (or R1) position, so that the slide in the O position forms a path.

[0092] As Figure 1 and Figures 18 to 26As shown, the operating mechanism 9 comprises an operating part upper shell 92, an operating part lower shell 93 and an operating part support 91, the operating part support 91 is substantially in the shape of a "C", which comprises an upper support 91a, a lower support 91b and a support body 91c, wherein the support body 91c is located between the lower support 91b and the upper support 91a, extends downwardly and rearwardly from the upper support 91a and is smoothly connected with the upper support 91a and the lower support 91b at the top and bottom of the support body 91c by circular arcs. The operating part upper shell 92 is fixed above the upper support 91a and the support body 91c and together with the upper support 91a forms an operating part top cover, the operating part lower shell 93 is fixed below the lower support 91b and the support body 91c and together with the lower support 91b forms an operating part base, and the support body 91c and the operating part upper shell 92 and the operating part lower shell 93 located outside the support body 91c together form a holding part of the operating mechanism 9. The holding part of the present application adopts a rearwardly inclined design, and the holding part, the operating part top cover and the operating part base are smoothly connected by circular arcs, so that the appearance of the whole operating mechanism is more beautiful and ergonomic, and it is convenient for the hand to stretch into the operating part top cover and the operating part base to push or pull the holding part forwardly or rearwardly.

[0093] Further, a light indicating part 97 is arranged between the operating part top cover and the operating part base. The light indicating part 97 comprises an upper transparent body 94 connected with the operating part top cover and a lower transparent body 95 connected with the operating part base. The upper transparent body 94 and the lower transparent body 95 of the present embodiment are both in the shape of a circular truncated cone, and the surfaces thereof are covered with diamond cut surfaces 943 facing different directions. In this way, when light reaches the upper transparent body 94 and the lower transparent body 95, a diamond-like colorful light effect is created, increasing the sense of technology of the whole vehicle. In addition, a plurality of relief LOGOs 944 (see Figure 25 ) are arranged in an array inside the upper transparent body 94. These relief LOGOs 944 are formed by a laser engraving process, are in a three-dimensional shape and form the LOGO of the vehicle manufacturer in array.

[0094] As Figure 18 and Figure 19As shown, the outer side of the holding part is provided with a P-stop button 922 which can slide relative to the holding part. The corresponding part of the upper shell 92 of the operating part is provided with a P-stop button slot 921 for accommodating the P-stop button 922. The P-stop button slot 921 is used for receiving and guiding the P-stop button 922 so that the P-stop button 922 can slide relative to the upper shell 92 of the operating part. The inner side of the holding part is further provided with an illumination circuit board 2 corresponding to the P-stop button 922. The illumination circuit board 2 is provided with a light source 23, a P-stop silica gel head 22 and a first connector 21. The light source 23 in this embodiment includes two LED lights. One of the two LED lights is located below the P-stop button 922 and is used for providing backlight function for the P-stop button 922 to illuminate the "P" character on the P-stop button 922. The other LED light is opposite to the light inlet surface of the light guide ring 96 so as to guide the light emitted by the light guide ring 96 to the light indicating part 97. The P-stop silica gel head 22 is located below the P-stop button 922 and is connected with the P-stop button 922. When the user presses the P-stop button 922, the P-stop silica gel head 22 can be pushed to contact the contact on the illumination circuit board 2 so that the light source 23 on the illumination circuit board 2 emits light. Since the P-stop signal is a key important signal, two groups of illumination circuits are arranged on the illumination circuit board 2 and two P-stop silica gel heads 22 are arranged correspondingly to perform P-stop function redundancy and ensure safety level. In order to improve the reliability of signal transmission, the operation signal of the P-stop is transmitted to the automobile MCU in two ways. One is transmitted through the LIN bus and the other is transmitted through the PSW copper sheet and the GND copper sheet. The transmission paths are redundantly designed and meet the requirements of relevant standards.
