[0050] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0051] The terms "first," "second," "third," "fourth," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0052] This invention provides an electronic gear shifting device.

[0053] like Figure 1 As shown, the electronic gear shifting device provided by the present invention includes a rotary wheel support 10, a rotary wheel 20 disposed on the rotary wheel support 10 and rotatable relative to the rotary wheel support 10, and a gear shifter 30 disposed below the rotary wheel support 10. The gear shifter 30 in this embodiment is the same as that of a conventional sliding electronic gear shifting device, capable of responding to the forward and backward sliding motion of the rotary wheel support 10. When the rotary wheel support 10 slides to a specific position, it sends a corresponding gear signal to achieve gear switching and has a self-return function. Its specific structure and control principle will not be elaborated further in this invention.

[0054] like Figures 2 to 4 As shown, the rotating wheel 20 provided by the present invention is made of highly transparent glass or crystal. Considering that the rotating wheel 20 will be repeatedly touched and has the requirement of light transmission during use, K9 glass / crystal is preferred. The rotating wheel 20 includes a rotating wheel body 20a and a rotating shaft 20b disposed on the rotating wheel body 20a. The rotating wheel body 20a is generally drum-shaped, and its outer contour surface is provided with diamond-cut facets, which include multiple facets facing different directions. In this embodiment, the diamond-cut facets include an upper cut facet 21 located on the upper side of the rotating wheel body 20a and a lower cut facet 22 located on the lower side of the rotating wheel body 20a. A generally cylindrical waist 23 is provided between the upper cut facet 21 and the lower cut facet 22, which provides a smooth feel during use. The upper and lower surfaces of the rotating wheel 20 are provided with an upper shaft hole 24 and a lower shaft hole 25 at their respective midpoints. In this embodiment, the rotating wheel 20 is provided with an axial through hole 26 at its midpoint, and the upper shaft hole 24 and the lower shaft hole 25 are stepped holes located at the upper and lower ends of the axial through hole 26, respectively. It can be understood that in other embodiments of the present invention, the axial through hole 26 may not be provided at the midpoint of the rotating wheel 20, and instead, an upper shaft hole 24 and a lower shaft hole 25 that do not penetrate the rotating wheel 20 may be provided at the upper and lower ends of the midpoint of the rotating wheel 20.

[0055] The upper facets 21 of the wheel 20 are similar in structure to the upper half of a standard diamond, including a table 211, a star facet 212, a kite facet 213, and a girdle facet 214. There are 12 groups of these facets (unlike the 8 groups in a diamond), distributed circumferentially along the upper half of the wheel 20. Each group of facets includes one star facet 212, one kite facet 213, and two girdle facets 214. These facets have different shapes and are arranged sequentially from one end of the wheel 20 towards the girdle 23. In the upper facets 21, the table facet 211 is located at the top of the wheel 20 and is a plane with a regular polygonal outer contour. In this embodiment, the outer contour of the table facet 211 is a regular dodecagon. Star surface 212 is an isosceles triangular plane, located below platform 211 and connected to the edge of platform 211, so that platform 211 and star surface 212 share the base of star surface 212. Kite surface 213 is a bilaterally symmetrical quadrilateral plane, located below star surface 212 and connected to the edge of star surface 212, so that two adjacent star surfaces 212 share the corresponding upper side of kite surface 213 with the kite surface 213 located between them. Waist surface 214 is similar to the triangular plane, but its base is curved. Waist surface 214 is located below kite surface 213, on the same side of kite surface 213 in the same group, two adjacent waist surfaces 214 share one side, and two adjacent waist surfaces 214 share the lower side of the corresponding kite surface 213 with two adjacent kite surfaces 213.

[0056] Unlike the diamond structure, the lower facet 22 of the wheel 20 adopts the same structure as the upper facet 21, including a table (not shown), a star facet 222, a kite facet 223, and a girdle facet 224. However, its arrangement is offset by one girdle facet relative to the upper facet 21. That is, the vertex of the kite facet 223 of the lower facet 22 is offset from the vertex of the kite facet 213 of the upper facet 21. The vertex of the kite facet 223 of the lower facet 22 is aligned with the common edge of the adjacent girdle facet 214 of the upper facet 21. In this embodiment, the offset angle is 360° / 12 / 2 = 15°. After the offset, when viewed from one side to the other, the number of facets in the visual effect is twice that when the kite facets 213 of the upper and lower facets 21 and 22 are aligned.

[0057] like Figure 2As shown, the rotary gear selector 10 is made of zinc-aluminum alloy using a die-casting process, and is roughly "C"-shaped. An upper housing 11 and a lower housing 12 are fixed to the rotary gear selector 10. The upper housing 11 and lower housing 12 can be made of plastic, or covered with leather, decorative parts, etc., to enhance the feel and overall appearance of the electronic shifter 30. A P-gear button (not shown) is located on the top of the upper housing 11. The P-gear button can slide up and down relative to the upper housing 11. When the P-gear button is pressed, the shifter 30 responds to the P-gear operation and sends a P-gear switching signal.

[0058] Please refer to the following: Figure 5 and Figure 6 The rotary wheel bracket 10 includes an upper bracket 10a, a lower bracket 10b, and a bracket body 10c located between the upper bracket 10a and the lower bracket 10b. The upper bracket 10a and the lower bracket 10b are respectively provided with stepped upper bushing mounting holes 101 and 102, and upper bushings 13 and lower bushings 14 are fixed within the upper bushing mounting holes 101 and 102, respectively. To ensure the rotational effect of the rotary wheel 20, the upper bushing mounting holes 101 and 102 are machined after die casting to enhance coaxiality. Furthermore, since the rotary wheel bracket 10 is an external component, its surface also requires electroplating or spraying treatment.

[0059] Please refer to the following: Figure 7 An upper circuit board bracket 15 is provided between the upper part 10a of the bracket and the upper shell 11 of the bracket. The upper circuit board bracket 15 is located above the upper bushing 13, and several fixing arms 15a protrude outward from its edge. The upper circuit board bracket 15 can be fixed to the upper part 10a of the bracket by screws passing through the fixing arms 15a. The upper part of the upper circuit board bracket 15 is used to fix the lighting circuit board 16, and the lower part is used to press the upper bushing 13. The lower surface of the lighting circuit board 16 is provided with a light source 16a, and the upper surface is provided with a silicone button. The silicone button is located below the P-position button and can contact the contact point on the lighting circuit board 16 when the P-position button is pressed, sending a P-position signal to the shifter 30 below the rotary bracket 10 and simultaneously illuminating the light source 16a on the lighting circuit board 16. In this embodiment, the light source 16a is an LED light, which is an RGB tri-color LED, which can emit light of different colors or effects according to the gear position signal.

[0060] Please refer to the following: Figure 8The upper bushing 13 is made of engineering plastic with self-lubricating properties (such as polyoxymethylene (POM), polytetrafluoroethylene (PTFE), etc.), and includes an upper bushing body 131 and a plurality of skirts 132 extending radially outward from the outer edge of the top end of the upper bushing body 131. The upper bushing body 131 is hollow cylindrical, and the shaft hole in the middle of the upper bushing 13 has radially inwardly protruding bosses distributed at intervals. These bosses are called first bosses 133. The first bosses 133 extend axially along the upper bushing body 131 and have an arc-shaped cross-section. The arc-shaped surface can reduce the contact area between the upper bushing 13 and the upper rotating shaft 27 disposed inside it, thereby reducing the wear of the upper bushing 13 and the upper rotating shaft 27 during the rotation of the rotating wheel 20. The lower end face of the upper bushing body 131 is provided with several protrusions 134. The surfaces of these protrusions 134 are arc surfaces, which can reduce the wear between the lower end face of the upper bushing 13 and the corresponding surface of the upper rotating shaft 27 during the rotation of the rotating wheel 20. The skirt 132 at the top of the upper bushing 13 is fan-shaped and is distributed circumferentially at intervals on the outer edge of the upper bushing 13. The skirt 132 is used to snap and fix with the corresponding groove on the rotating wheel bracket 10, so that the upper bushing 13 does not rotate or move relative to the rotating wheel bracket 10.

[0061] Please refer to the following: Figures 9 to 11The rotating shaft 20b is provided with a light-incident surface opposite to the light source 16a, a transmission surface for light to pass through, and a reflection surface for reflecting light back to the rotating wheel body 20a. Light emitted from the light source 16a can enter the rotating shaft 20b through the light-incident surface, be transmitted through the transmission surface, or be reflected by the reflection surface before being directed to the rotating wheel body 20a. Specifically, the rotating shaft 20b includes an upper rotating shaft 27 and a lower rotating shaft 28. The upper rotating shaft 27 is closer to the light source 16a, and the lower rotating shaft 28 is farther away from the light source 16a. The upper rotating shaft 27 is disposed within the upper bushing 13 and is fixedly connected to the rotating wheel 20 by interference fit or adhesive bonding. The upper rotating shaft 27 is made of transparent PC and serves as a light guide, light focus, and friction shaft. The upper rotating shaft 27 includes a light guide portion 271 near the light source 16a, a first locking portion 272 and a first contact portion 273 located in the middle of the upper rotating shaft 27, and a light-transmitting and reflective portion 274 far away from the light source 16a. In this embodiment, the light guide 271 is a hollow cylinder with a light-concentrating surface 271a at the bottom of its central hole. The light-concentrating surface 271a is the light-incident surface of the rotating shaft 20b. This light-concentrating surface 271a is a convex lens surface used to converge the conical light emitted by the LED and conduct it downwards. In this embodiment, the first locking part 272 is located below the light guide 271 and is a flange that protrudes radially from other parts of the upper rotating shaft 27. This flange and the upper rotating shaft part below it form a stepped surface to cooperate with the upper shaft hole 24 provided on the rotating wheel 20, positioning the upper rotating shaft 27 into the upper shaft hole 24 of the rotating wheel 20. The first contact part 273 is located below the first locking part 272. In this embodiment, the first contact part 273 is generally cylindrical, and its bottom edge includes multiple arcs connected end to end. Its diameter is equal to the diameter of the lower half of the upper shaft hole 24, so that the first contact portion 273 can contact and support the inner surface of the upper shaft hole 24 when the upper rotating shaft 27 is placed in the upper shaft hole 24, preventing the upper rotating shaft 27 from shaking in the upper shaft hole 24. In this embodiment, the light-transmitting and reflecting portion 274 is provided with a transmitting surface and a reflecting surface, specifically including a first transmitting surface 274a, a second transmitting surface 274b, a third transmitting surface 274c, and a first reflecting surface 274d. There are multiple first transmitting surfaces 274a, second transmitting surfaces 274b, and first reflecting surfaces 274d, and only one third transmitting surface 274c. The first transmitting surface 274a is approximately an isosceles trapezoidal plane. These first transmitting surfaces 274a extend inward and downward from the bottom end of the first contact portion 273, forming a first angle with the axis of the upper rotating shaft 27. The second transmitting surface 274b is quadrilateral, extending outward and downward from the bottom end of the first transmitting surface 274a. The second transmission surface 274b is slightly inclined outward relative to the axis of the upper rotating shaft 27, forming a second included angle with the axis of the upper rotating shaft 27.The first reflecting surface 274d is an inverted isosceles trapezoidal plane, located below the second transmitting surface 274b. It extends downward and inward from the bottom end of the second transmitting surface 274b, forming a third angle with the axis of the upper rotating shaft 27. In this embodiment, the first, second, and third angles are all acute angles, and the first and third angles are both greater than the second angle. The third transmitting surface 274c is a regular polygon, specifically a regular decagon in this embodiment. That is, there are ten corresponding first transmitting surfaces 274a, second transmitting surfaces 274b, and first reflecting surfaces 274d. It is understood that in other embodiments of the present invention, the third transmitting surface 274c may also be other regular polygons. The third transmitting surface 274c is located at the bottom of the first reflecting surface 274d, is arranged horizontally, and the outer contour edge of the third transmitting surface 274c coincides with the bottom edge of the first reflecting surface 274d.

[0062] Please see Figure 9 , Figure 12 and Figure 13The lower rotating shaft 28 is also made of transparent PC and includes a reflective part 281 at the top, a second locking part 282 and a second contact part 283 in the middle, and a support part 284 at the bottom. In this embodiment, the reflective part 281 has reflective surfaces, specifically a second reflective surface 281a and a third reflective surface 281b. The second reflective surface 281a is a horizontal plane located at the top of the lower rotating shaft 28 and is a regular polygon in shape. The third reflective surface 281b is similar to a fan-shaped ring, but its top is straight. The third reflective surface 281b slopes downwards and outwards from the edge of the second reflective surface 281a, forming a fourth angle with the axis of the lower rotating shaft 28. In this embodiment, there are six second reflective surfaces 281a and six third reflective surfaces 281b, and the fourth angle is acute. It is understood that in other embodiments of the present invention, the second reflective surface 281a may not be provided, so that the tops of all the third reflective surfaces 281b intersect at a single point. In this embodiment, the shape of the third reflective surface 281b is fan-shaped. The second contact portion 283 is located below the reflective portion 281. In this embodiment, the second contact portion 283 is similar to a cylinder, and its diameter is equal to the diameter of the upper half of the lower shaft hole 25. This allows the second contact portion 283 to contact and support the inner surface of the lower shaft hole 25 when the lower shaft 28 is placed inside the lower shaft hole 25, preventing the lower shaft 28 from shaking inside the lower shaft hole 25. The second locking portion 282 is located below the second contact portion 283. In this embodiment, the second locking portion 282 is a flange that protrudes radially from the lower shaft 28. The flange and the upper part of the lower shaft form a stepped surface to cooperate with the lower shaft hole 25 provided on the rotating wheel 20, positioning the lower shaft 28 inside the lower shaft hole 25 of the rotating wheel 20. The support portion 284 is located below the second locking portion 282. In this embodiment, the support portion 284 is cylindrical. An arc-shaped protrusion 284a is provided at the center of the bottom of the support portion 284. The protrusion 284a and the lower bushing 14 below it form a spherical friction pair, which can reduce the contact area between the lower rotating shaft 28 and the lower bushing 14 and reduce the wear of the lower rotating shaft 28.

[0063] Please refer to this document. Figure 9When the LED light is working, the light emitted is focused by the focusing surface 271a and then transmitted downwards. The light path is divided into the following parts: part of the light passes through the first transmission surface 274a and shines on the inner cylindrical surface of the rotating wheel 20; part of the light shines on the first reflecting surface 274d and is reflected onto the opposite second transmission surface 274b, from which it passes through and is transmitted to the inner cylindrical surface of the rotating wheel 20; another part of the light passes directly through the third transmission surface 274c and shines on the second reflecting surface 281a or the third reflecting surface 281b, and then is reflected from the second reflecting surface 281a or the third reflecting surface 281b to the inner cylindrical surface of the rotating wheel 20. In this way, the light transmitted through different paths all passes through the rotating wheel 20 and then exits from the diamond-cut facets on the surface of the rotating wheel 20. Because the diamond-cut facets are designed with included angles, the light emitted from the surface of the rotating wheel 20 can achieve a colorful effect. Since the rotating wheel 20 can rotate, the color effect will change continuously like a marquee as it rotates, and due to the angle, there will also be a color-changing effect.

[0064] It should be noted that not all types of LED light emitted can pass through the first transmission surface 274a and reach the inner cylindrical surface of the rotating wheel 20. Whether light can pass through the first transmission surface 274a and reach the inner cylindrical surface of the rotating wheel 20 depends on the coverage area of ​​the light emitted by the LED light and the focusing degree of the focusing surface 271a. If the coverage area of ​​the light emitted by the LED light is small, or the focusing degree of the focusing surface 271a is strong, no light will pass through the first transmission surface 274a and reach the inner cylindrical surface of the rotating wheel 20. It should also be noted that the present invention has specially designed the angles of the first transmission surface 274a, the second transmission surface 274b, the third transmission surface 274c, the first reflecting surface 274d, the second reflecting surface 281a, and the third reflecting surface 281b, following the laws of reflection and refraction, so that all transmitted light rays are perpendicular to the corresponding surfaces when they pass through.

[0065] Please see Figure 2 and Figure 14The lower bushing 14 is located below the lower rotating shaft 28. The lower bushing 14 includes a disc-shaped bushing bottom 141 and a receiving portion 142 extending upward from near the edge of the bushing bottom 141. The receiving portion 142 is a hollow cylinder, forming a space inside to receive the lower rotating shaft 28. The support portion 284 of the lower rotating shaft 28 is located in this space, forming a spherical friction pair with the bushing bottom 141 of the lower bushing 14. The receiving portion 142 of the lower bushing 14 also has radially inwardly protruding bosses distributed at intervals. These bosses are called second bosses 143. The second bosses 143 extend axially along the receiving portion 142, and their cross-section is arc-shaped. This arc-shaped surface can reduce the contact area between the lower bushing 14 and the lower rotating shaft 28 disposed inside it, thereby reducing the wear of the lower bushing 14 and the lower rotating shaft 28 during the rotation of the rotating wheel 20. Furthermore, the bottom edge of the bushing 141 is provided with several downwardly extending spring pieces 144. These spring pieces 144 abut against the lower circuit board support 17 below the lower bushing 14, eliminating the gap between the rotating wheel 20 and the upper and lower rotating shafts 28 and providing a buffering effect. In this invention, the stiffness of the spring piece 144 structure takes into account the weight of the crystal rotating wheel 20 and the impact of acceleration on bumpy roads. The structure of the lower circuit board support 17 is similar to that of the upper circuit board support 15, and will not be described again here. Below the lower circuit board support 17, there is a relay circuit board 18, which mainly serves to relay electrical signals, realizing the vertical transmission of electrical signals.

[0066] The assembly process of the rotary electronic shifting device of the present invention is as follows:

[0067] First, the upper rotating shaft 27 and the lower rotating shaft 28 are respectively installed into the upper shaft hole 24 and the lower shaft hole 25 of the rotating wheel 20. The upper rotating shaft 27 and the lower rotating shaft 28 are fixed to the upper shaft hole 24 and the lower shaft hole 25 by interference fit or adhesive. After assembly, the upper rotating shaft 27 and the lower rotating shaft 28 do not move relative to the upper shaft hole 24 and the lower shaft hole 25 in the working state.

[0068] Next, place the rotating wheel 20 between the upper part 10a and the lower part 10b of the rotating wheel bracket 10, so that the upper shaft hole 24 and the lower shaft hole 25 of the rotating wheel 20 are roughly aligned with the upper bushing mounting hole 101 and the lower bushing mounting hole 102 of the rotating wheel bracket 10.

[0069] Then, the upper bushing 13 is installed into the rotating wheel bracket 10 from the top, so that the shaft hole of the upper bushing 13 and the outer cylindrical surface of the upper rotating shaft 27 form a rotational friction pair. The protrusion 134 on the lower end face forms a point-to-surface friction pair with the corresponding end face of the upper rotating shaft 27. The outer cylindrical surface of the upper bushing 13 is fitted with the upper bushing mounting hole 101 of the rotating wheel bracket 10. The skirt 132 of the upper bushing 13 is inserted into the groove on the rotating wheel bracket 10, which limits the upper bushing 13 in the rotation direction and prevents the upper bushing 13 from rotating relative to the rotating wheel bracket 10. At the same time, it strengthens the connection rigidity between the upper bushing 13 and the rotating wheel bracket 10, making the rotating wheel 20 feel more solid when it is working.

[0070] Next, place the upper circuit board bracket 15 above the upper bushing 13, so that the lower end face of the upper circuit board bracket 15 abuts against the upper end face of the upper bushing 13, and position the upper bushing 13 in the Z direction. Then, fix the upper circuit board bracket 15 to the rotating wheel bracket 10 with four screws.

[0071] Then, the lighting circuit board 16 is mounted on the upper circuit board bracket 15, so that the light source is aligned with the focusing surface 271a of the upper rotating shaft 24. Then, the X-axis, Y-axis and each axial rotational freedom of the lighting circuit board 16 are restricted, and the lighting circuit board 16 is pre-pressed and fixed in the Z-axis by silicone buttons, P-position buttons, etc.

[0072] Next, the lower bushing 14 and the lower circuit board bracket 17 are sequentially installed from the bottom of the wheel bracket 10. The assembly method and function are similar to those of the upper bushing 13 and the upper circuit board bracket 15, and will not be described again here. In particular, since the lower bushing 14 is provided with four spring pieces 144, it will be in a pre-compression state after assembly. After a period of use, when the bushing and the shaft wear, the spring pieces 144 will release some deformation to fill the gap caused by the wear, so that the fit between the bushing and the shaft is in a zero-gap state, and there will be no impact noise when passing over bumpy roads.

[0073] Through the structural design of the aforementioned rotary wheel and electronic shifting device, when needed, the driver can hold the rotary wheel bracket and flick the wheel with their fingers, allowing it to rotate freely. Besides fulfilling the shifting function itself, it also provides a "playful" and "entertaining" experience, achieving a "stress-relieving" purpose. Furthermore, this invention incorporates a light source above the rotary wheel, utilizing the transparency of crystal and its "diamond" facets, along with the wheel's rotational characteristics, to create a colorful and "sparkling" effect, enhancing the technological feel of the electronic shifting device. The rotary wheel design of this invention features a specific rotating pair; the crystal material does not directly serve as a friction pair. The rotating pair consists of a bushing made of a self-lubricating material and a rotating shaft. The rotating shaft utilizes... Transparent plastic with certain frictional properties serves as both a rotating pair and a light guide. The shaft design takes light transmission into account, featuring functions such as focusing, reflection, and refraction. The shaft rotates with the wheel, and the cut surface on it rotates accordingly, creating a dynamic effect for the light. Furthermore, considering processing errors during crystal cutting, a spring is designed on the lower bushing to absorb gaps caused by processing errors, assembly errors, and wear, ensuring smooth rotation of the wheel. The wheel support is made of die-cast metal followed by machining, utilizing the metal material to guarantee its strength and rigidity, and machining to ensure its positioning accuracy.

[0074] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
