Description

Technical Field

[0001] The present invention relates to the technical field of gear shifters, and in particular to an electronic gear shifter structure. Background Art

[0002] As the core interface between the driver and the transmission, the reliability of the automotive shifter directly impacts the driving experience and safety. The push-rod shifter, currently widely used in the market, primarily consists of a housing and a shift lever. The housing features a ball-and-socket structure on the upper portion and a guide rail on the lower portion. The shift lever pivots onto the ball-and-socket structure via a ball joint, enabling rotation of the lever. Simultaneously, the end of the shift lever slides against the guide rail, limiting the lever's rotational direction and enabling shifting between gears.

[0003] However, in actual use, it was found that when the shift lever rotates around the ball joint, due to processing errors and assembly errors, the sliding fit between the end of the shift lever and the guide rail may fluctuate, which in turn leads to increased wear and tear, and urgently needs improvement. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when the shift lever rotates around the ball joint, due to the existence of processing errors and assembly errors, the sliding fit between the end of the shift lever and the guide rail may fluctuate, thereby causing increased wear.

[0005] To solve the above problems, the present invention provides an electronic shifter structure, comprising a housing having a ball-and-socket structure on the upper portion and a guide rail on the lower portion, and further comprising: A shift lever is arranged vertically and has an axially opened guide hole at its lower end. A coaxial limiting hole with a reduced diameter is provided at the bottom of the guide hole. A ball joint is provided in the middle of the shift lever and the ball joint is rotatably engaged with the ball and socket structure. A limiting shaft is vertically arranged in the guide hole, the upper end of the limiting shaft is provided with a limiting end slidably inserted into the limiting hole, the side wall of the limiting end is provided with a plurality of slots distributed along the circumferential direction, the slots penetrate to the upper end surface of the limiting end, and the lower end of the limiting shaft is provided with a guide block with an increased diameter, the upper end of the guide block is clearance-fitted with the guide hole and the lower end is slidably fitted to the guide rail; The centering assembly includes a spring, a limiting ring and a centering ring which are sequentially mounted on the limiting shaft from top to bottom. The upper end of the spring abuts against the bottom of the guide hole and the lower end abuts against the upper side of the limiting ring. The inner circumference of the limiting ring slides with the limiting shaft and a gap is left between the outer circumference and the guide hole. The inner circumference of the centering ring leaves a gap with the limiting shaft and the outer circumference slides with the guide hole. The lower side of the centering ring abuts against the guide block and an annular guide slope is provided between the upper side and the inner side. The lower side of the limiting ring abuts against the guide slope.

[0006] Compared with the prior art, the above scheme optimizes the design of the shift lever, opens a guide hole at the lower end of the shift lever, and sets the limit shaft in the guide hole. When the shift lever rotates with the ball joint as the center, since the upper end of the limit shaft is slidably inserted into the limit hole, the limit shaft can be axially extended and retracted relative to the guide hole. At the same time, there is a gap between the upper part of the guide block and the guide hole, so that the guide block has a certain radial activity space. Therefore, the fluctuation of the sliding fit between the guide rail and the guide block can be effectively absorbed and offset, significantly reducing wear and other problems; at the same time, the limit ring is pushed toward the guide inclined surface of the self-aligning ring under the action of the spring. Since the outer peripheral side of the self-aligning ring slides with the guide hole and the inner peripheral side has a gap with the limit shaft, the self-aligning ring can ensure good concentricity relative to the guide hole. Since there is a gap between the outer peripheral side of the limit ring and the guide hole, the guide inclined surface of the self-aligning ring will align the limit ring, ensuring the concentricity of the limit ring and the limit shaft relative to the guide hole, and improving the stability of the guide shaft and guide block during movement. In addition, the limiting end of the limiting shaft has a certain deformation ability by being provided with a slot, thereby improving the stability of the limiting end sliding in the limiting hole.

[0007] In an improved solution, a convex shaft is respectively provided on the left and right sides of the ball joint and the axis of the convex shaft passes through the center of the ball joint, and a limiting cavity is respectively provided on the left and right parts of the shell, and the two convex shafts are respectively located in the two limiting cavities, and the upper cavity wall and the lower cavity wall of the limiting cavity leave a distance relative to the convex shaft so that the ball joint can rotate with the front and rear directions as the axis, and the front cavity wall and the rear cavity wall of the limiting cavity have a limiting portion abutting against the convex shaft, wherein the abutment of the front cavity wall and the rear cavity wall of the limiting cavity against the convex shaft limits the ball joint from rotating with the left and right directions as the axis but not rotating with the up and down directions as the axis, and at the same time, the upper cavity wall and the lower cavity wall of the limiting cavity leave a distance relative to the convex shaft so that the ball joint can rotate with the front and rear directions as the axis.

[0008] In an improved solution, the free end of the convex shaft has a stepped platform with a reduced outer diameter, and the limiting portion is a vertical boss protruding from the front cavity wall and the rear cavity wall of the limiting cavity respectively, and a distance is left between the boss and the stepped surface of the step to limit the rotation angle of the ball joint with the front and rear directions as the axis, and the boss abuts against the outer peripheral wall of the step, so that when the ball joint rotates, only wear will occur between the boss and the outer peripheral wall of the step, reducing the problem of wear on the convex shaft and other positions of the limiting cavity.

[0009] In an improved solution, the ball and socket structure includes two limit sleeves arranged in a front and rear manner, a gap for the cam shaft to pass through is provided between the two limit sleeves, and two limit cavities are connected to the gap between the two limit sleeves, and the opposite surfaces of the two limit sleeves are respectively provided with spherical receiving grooves, and the ball joint is rotatably fitted between the receiving grooves of the two limit sleeves, and the upper ends of the two limit sleeves are provided with an upper opening for the upper end of the shift lever to extend and move, and the lower ends are provided with a lower opening for the lower end of the shift lever to extend and move. The assembly is simple and convenient, and during subsequent maintenance, the worn limit sleeves only need to be replaced without replacing the outer shell.

[0010] In an improved solution, the shell includes an upper shell and a lower shell, the lower shell is provided with a mounting groove for two limit sleeves to be embedded, the two limit cavities are respectively located on the left and right sides of the mounting groove, and the upper shell is detachably connected to the upper side of the lower shell and realizes the closure of the mounting groove and the upper side of the limit cavity, thereby realizing stable assembly of the limit sleeve relative to the shell.

[0011] In an improved solution, a magnetic part is provided on the front or rear side of the ball joint, and a magnetic part is provided on the front or rear side of the ball joint. The housing is provided with an identification chip corresponding to the magnetic part, so that when the ball joint rotates, the magnetic part generates a changing magnetic field, and then the identification chip identifies the posture of the ball joint according to different magnetic fields to correspond to different gears.

[0012] In an improved solution, the outer side of the ball joint is covered with a plastic coating, thereby improving the fit between the ball joint and the receiving groove through the plastic coating, and improving the stability of the ball joint when rotating between the receiving grooves of the two limiting sleeves.

[0013] In an improved solution, the lower part of the guide block is a conical structure that gradually decreases from top to bottom, and the guide rail is groove-shaped and includes an origin located below the guide block, a first groove section extending from the origin to the upper left, a second groove section extending from the origin to the upper right, and a third groove section extending forward or backward from the origin. The bottom surface of the conical structure of the guide block slides against the guide rail, so that when the guide block slides in the first groove section and the second groove section, the corresponding ball joint rotates with the left and right direction as the axis; when the guide block slides in the third groove section, the corresponding ball joint rotates with the front and rear direction as the axis.

[0014] In an improved solution, the lower end of the slot extends to the guide hole, so that the guide hole and the limiting hole are connected through the slot, thereby achieving connection between the limiting hole and the guide hole through the slot, avoiding the problem of air pressure imbalance in the limiting hole.

[0015] In an improved solution, there are four slots that are evenly spaced, so that the deformation capacity of the limiting end of the limiting shaft is more balanced, further improving the stability of the limiting end sliding in the limiting hole. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figure 1-Figure 7 An embodiment of the present invention provides an electronic shifter structure, comprising a housing 1 having a ball-and-socket structure on the upper portion and a guide rail 12 on the lower portion, and further comprising: The shift lever 2 is vertically arranged and has an axially extending guide hole 21 at its lower end. A coaxial limiting hole 22 with a reduced diameter is provided at the bottom of the guide hole 21. A ball joint 23 is provided in the middle of the shift lever 2 and is rotatably engaged with the ball and socket structure. The limiting shaft 3 is vertically arranged in the guide hole 21. The upper end of the limiting shaft 3 is provided with a limiting end that is slidably inserted into the limiting hole 22. The side wall of the limiting end is provided with a plurality of slots 31 distributed along the circumferential direction. The slots 31 extend through the upper end surface of the limiting end. The lower end of the limiting shaft 3 is provided with a guide block 32 with an increased diameter. The upper end of the guide block 32 is clearance-fitted with the guide hole 21 and the lower end is slidably fitted into the guide rail 12. The centering assembly 4 includes a spring 41, a limiting ring 42 and an aligning ring 43, which are sequentially arranged on the limiting shaft 3 from top to bottom. The upper end of the spring 41 abuts against the bottom of the guide hole 21 and the lower end abuts against the upper side of the limiting ring 42. The inner circumference of the limiting ring 42 slides with the limiting shaft 3 and the outer circumference has a gap with the guide hole 21. The inner circumference of the centering ring 43 has a gap with the limiting shaft 3 and the outer circumference has a slidable fit with the guide hole 21. The lower side of the centering ring 43 abuts against the guide block 32 and an annular guide slope 431 is provided between the upper side and the inner side. The lower side of the limiting ring 42 abuts against the guide slope 431.

[0023] In addition, a gap is left between the outer circumference of the limiting ring 42 and the guide hole 21, which means that the outer diameter of the limiting ring 42 is smaller than the aperture of the guide hole 21, thereby forming a clearance fit; a gap is left between the inner circumference of the centering ring 43 and the limiting shaft 3, which means that the inner diameter of the centering ring 43 is larger than the outer diameter of the limiting shaft 3, thereby forming a clearance fit.

[0024] The above solution optimizes the design of the shift lever 2 by defining a guide hole 21 at the lower end of the shift lever 2 and disposing the limit shaft 3 in the guide hole 21. When the shift lever 2 rotates about the ball joint 23, the upper end of the limit shaft 3 is slidably inserted into the limit hole 22, allowing the limit shaft 3 to extend and retract axially relative to the guide hole 21. Simultaneously, the upper portion of the guide block 32 is clearance-fitted with the guide hole 21, allowing the guide block 32 to have a certain radial movable space. Therefore, fluctuations in the sliding fit between the guide rail 12 and the guide block 32 can be effectively absorbed and offset, significantly reducing wear and other problems. At the same time, the limiting ring 42 is pushed toward the guiding bevel 431 of the centering ring 43 by the action of the spring 41. The guiding bevel 431 is preferably in the shape of a small cone with upper and lower parts. Since the outer circumference of the centering ring 43 slides with the guide hole 21 and the inner circumference is in clearance with the limiting shaft 3, the centering ring 43 can ensure good concentricity relative to the guide hole 21. Since there is a gap between the outer circumference of the limiting ring 42 and the guide hole 21, the guiding bevel 431 of the centering ring 43 will align the limiting ring 42, ensuring the concentricity of the limiting ring 42 and the limiting shaft 3 relative to the guide hole 21, and improving the stability of the guide shaft and guide block 32 during movement. In addition, the groove 31 is provided at the limiting end of the limiting shaft 3, so that the limiting end of the limiting shaft 3 has a certain deformation ability, which effectively improves the stability of the limiting end sliding in the limiting hole 22.

[0025] Combine Figure 2 As shown, in this embodiment, a convex shaft 231 is respectively provided on the left and right sides of the ball joint 23, and the axis of the convex shaft 231 passes through the center of the ball joint 23, and a limiting cavity 13 is respectively provided on the left and right parts of the shell 1, and the two convex shafts 231 are respectively located in the two limiting cavities 13, and the upper cavity wall and the lower cavity wall of the limiting cavity 13 leave a distance relative to the convex shaft 231 so that the ball joint 23 can rotate with the front and rear directions as the axis, and the front cavity wall and the rear cavity wall of the limiting cavity 13 have a limiting portion abutting against the convex shaft 231, wherein the front cavity wall and the rear cavity wall of the limiting cavity 13 abut against the convex shaft 231 through the limiting portion, thereby limiting the ball joint 23 from rotating with the left and right directions as the axis but not the up and down directions as the axis, and at the same time, the upper cavity wall and the lower cavity wall of the limiting cavity 13 leave a distance relative to the convex shaft 231, so that the ball joint 23 can rotate with the front and rear directions as the axis.

[0026] Furthermore, the free end of the protruding shaft 231 has a stepped platform 231a with a reduced outer diameter, and the limiting portion is a vertical boss 131 protruding from the front cavity wall and the rear cavity wall of the limiting cavity 13 respectively, and a distance is left between the boss 131 and the stepped surface of the step 231a to limit the rotation angle of the ball joint 23 with the front and rear directions as the axis. The boss 131 abuts against the outer peripheral wall of the step 231a, so that when the ball joint 23 rotates, only wear will occur between the boss 131 and the outer peripheral wall of the step 231a, reducing the problem of wear on the protruding shaft 231 and other positions of the limiting cavity 13.

[0027] In this embodiment, the ball and socket structure includes two limit sleeves 11 arranged in front and behind, and there is a gap between the two limit sleeves 11 for the convex shaft 231 to pass through, and the two limit cavities 13 are connected to the gap between the two limit sleeves 11. The opposite surfaces of the two limit sleeves 11 are respectively provided with spherical receiving grooves 111, and the ball joint 23 is rotatably fitted between the receiving grooves 111 of the two limit sleeves 11. The upper ends of the two limit sleeves 11 are provided with an upper opening 112 for the upper end of the shift lever 2 to extend and move, and the lower ends are provided with a lower opening 113 for the lower end of the shift lever 2 to extend and move. The assembly is simple and convenient, and during subsequent maintenance, the worn limit sleeves 11 only need to be replaced without replacing the outer shell 1.

[0028] In this embodiment, the shell 1 includes an upper shell 101 and a lower shell 102. The lower shell 102 is provided with a mounting groove 102a for two limit sleeves 11 to be embedded in. The two limit cavities 13 are respectively located on the left and right sides of the mounting groove 102a. The upper shell 101 is detachably connected to the upper side of the lower shell 102 and realizes the closure of the mounting groove 102a and the upper side of the limit cavity 13, thereby realizing stable assembly of the limit sleeve 11 relative to the shell 1.

[0029] Combine Figure 5 As shown, in this embodiment, a magnetic member 232 is provided on the front or rear side of the ball joint 23, and the housing 1 is provided with an identification chip corresponding to the magnetic member 232, so that when the ball joint 23 rotates, the magnetic member 232 generates a changing magnetic field, and then the identification chip identifies the posture of the ball joint 23 according to different magnetic fields to correspond to different gears.

[0030] Furthermore, the outer side of the ball joint 23 is covered with a plastic coating 234, which closes the notch of the slot 233, thereby improving the fit between the ball joint 23 and the receiving groove 111 through the plastic coating 234, and improving the stability of the ball joint 23 when rotating between the receiving grooves 111 of the two limit sleeves 11.

[0031] Combine Figure 6As shown, in this embodiment, the lower part of the guide block 32 is a conical structure that gradually decreases from top to bottom, and the guide rail 12 is groove-shaped and includes an origin located below the guide block 32, a first groove section 121 extending forward and upward from the origin, a second groove section 122 extending backward and upward from the origin, and a third groove section 123 extending left or right from the origin. The bottom surface of the conical structure of the guide block 32 slides against the guide rail 12, so that when the guide block 32 slides in the first groove section 121 and the second groove section 122, the corresponding ball joint 23 rotates with the left and right direction as the axis; when the guide block 32 slides in the third groove section 123, the corresponding ball joint 23 rotates with the front and rear direction as the axis.

[0032] Furthermore, the bottom surface of the conical structure of the guide block 32 is spherical, and the cross-section of the guide rail 12 is adapted to the bottom surface shape of the conical structure of the guide block 32 , thereby effectively improving the stability of the sliding fit between the guide block 32 and the guide rail 12 .

[0033] In this embodiment, there are four slots 31 evenly spaced apart, thereby making the deformation capacity of the limiting end of the limiting shaft 3 more balanced and further improving the stability of the limiting end sliding within the limiting hole 22. The lower end of the slot 31 extends to the guide hole 21, so that the guide hole 21 and the limiting hole 22 are connected through the slot 31. The slot 31 thus connects the limiting hole 22 to the guide hole 21, thereby avoiding the problem of air pressure imbalance in the limiting hole 22.
