[0053] 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.
[0054] 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.
[0055] This invention provides a light guide wheel and an electronic shifting device having the same.
[0056] like Figure 1 As shown, the electronic gear shifting device provided by the present invention includes a rotary wheel bracket 10, a light guide wheel 20 disposed on the rotary wheel bracket 10 and rotatable relative to the rotary wheel bracket 10, and a gear shifter 30 disposed below the rotary wheel bracket 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 bracket 10. When the rotary wheel bracket 10 slides to a specific position, it sends a corresponding gear shifting signal to achieve gear switching and has a self-returning function. Its specific structure and control principle will not be elaborated further in this invention.
[0057] like Figures 2 to 4As shown, the light guide rotating wheel 20 is made of high transparency glass or crystal, and preferably K9 glass / crystal, considering that the light guide rotating wheel 20 will be repeatedly touched and has light transmission requirement in use. The light guide rotating wheel 20 comprises a rotating wheel body 20a and a rotating shaft 20b arranged on the rotating wheel body 20a. The shape of the rotating wheel body 20a is generally drum-shaped, and a diamond cut surface is arranged on the outer contour surface of the rotating wheel body 20a. The diamond cut surface comprises a plurality of cut surfaces facing different directions. The diamond cut surface in the embodiment comprises a first cut surface 21 on the upper side of the rotating wheel body 20a and a second cut surface 22 on the lower side of the rotating wheel body 20a. A generally cylindrical waist 23 is arranged between the first cut surface 21 and the second cut surface 22, so that a smooth hand feeling can be obtained in use. A first shaft hole 24 and a second shaft hole 25 are arranged on the middle part of the upper and lower surfaces of the light guide rotating wheel 20. In the embodiment, an axial through hole 26 is arranged on the middle part of the light guide rotating wheel 20, and the first shaft hole 24 and the second shaft hole 25 are step holes arranged on the upper and lower ends of the axial through hole 26. It can be understood that in other embodiments of the present application, the axial through hole 26 can not be arranged on the middle part of the light guide rotating wheel 20, and the first shaft hole 24 and the second shaft hole 25 can be arranged on the upper and lower ends of the middle part of the light guide rotating wheel 20 without penetrating the light guide rotating wheel 20.
[0058] The first cut surface 21 of the light guide rotating wheel 20 is similar to the upper half structure of a standard diamond, comprising a table 211, a star surface 212, a kite surface 213 and a girdle 214. These table 211, star surface 212, kite surface 213 and girdle 214 have 12 groups (different from 8 groups of diamond), which are distributed on the upper half part of the light guide rotating wheel 20 in the circumferential direction. Each group of cut surfaces comprises one star surface 212, one kite surface 213 and two girdles 214. These star surfaces 212, kite surfaces 213 and girdles 214 have different shapes, and are arranged in sequence from one end of the light guide rotating wheel 20 to the waist 23. In the first cut surface 21, the table 211 is located at the top of the light guide rotating wheel 20, and is a plane with a regular polygonal contour. In the embodiment, the contour of the table 211 is a regular dodecagon. The star surface 212 is an isosceles triangular plane, which is located below the table 211 and connected with the edge of the table 211, so that the table 211 and the star surface 212 share the bottom edge of the star surface 212. The kite surface 213 is a left-right symmetrical quadrilateral plane, which is located below the star surface 212 and connected with the edge of the star surface 212, so that the adjacent two star surfaces 212 share the corresponding upper edges of the kite surface 213 located between them. The girdle 214 is similar to a triangular plane, but its bottom edge is an arc. The girdle 214 is located below the kite surface 213 and on the same side of the kite surface 213 in the same group. The adjacent two girdles 214 share one edge, and the adjacent two girdles 214 share one edge of the lower part of the corresponding kite surface 213 with the adjacent two kite surfaces 213, respectively.
[0059] Different from the diamond structure, the second cutting surface 22 of the light guide runner 20 adopts the same structure as the first cutting surface 21, and also includes a table surface (not shown), a star surface 222, a kite surface 223 and a girdle surface 224, but the arrangement position thereof is offset by one girdle surface relative to the first cutting surface 21, that is, the vertex of the kite surface 223 of the second cutting surface 22 is offset from the vertex of the kite surface 213 of the first cutting surface 21, and the vertex of the kite surface 223 of the second cutting surface 22 is aligned with the common edge of the adjacent girdle surface 214 of the first cutting surface 21. In the embodiment, the offset angle of the two is 360° / 12 / 2=15°. After the offset, the number of cutting surfaces in the visual effect when viewed from one side to the other side is equivalent to twice the number of the kite surfaces 213 of the first and second cutting surfaces 21 and 22 when the kite surfaces 213 are aligned.
[0060] As shown in Figure 2 , the runner bracket 10 is made of zinc-aluminum alloy material by pressure casting process, and is generally in the shape of a "C" letter. The runner bracket 10 is fixed with a bracket upper shell 11 and a bracket lower shell 12, which can be made of plastic, or coated with leather, appearance decoration and the like outside the plastic, so as to increase the feel and overall appearance of the electronic gear shifting device 30. The top of the bracket upper shell 11 is provided with a P-gear button (not shown), which can slide up and down relative to the bracket upper shell 11. When the P-gear button is pressed down, the gear shifter 30 will respond to the P-gear operation and send a P-gear switching signal.
[0061] Please refer to Figure 5 and Figure 6 , the runner bracket 10 includes a bracket upper portion 10a, a bracket lower portion 10b, and a bracket main body 10c between the bracket upper portion 10a and the bracket lower portion 10b. The bracket upper portion 10a and the bracket lower portion 10b are respectively provided with a stepped first bushing mounting hole 101 and a second bushing mounting hole 102, and the first bushing 13 and the second bushing 14 are respectively fixed in the first bushing mounting hole 101 and the second bushing mounting hole 102. In order to ensure the rotation effect of the light guide runner 20 rotating pair, the first bushing mounting hole 101 and the second bushing mounting hole 102 are machined after pressure casting to strengthen the coaxiality. Moreover, since the runner bracket 10 is an appearance part, the surface of the runner bracket 10 also needs to be electroplated or sprayed.
[0062] Please refer to Figure 7The first circuit board support 15 is located above the first bushing 13, and its edges extend outwardly by a plurality of fixing arms 15a. The first circuit board support 15 can be fixed to the upper bracket 10a by screws passing through the fixing arms 15a. The upper part of the first circuit board support 15 is used to fix the lighting circuit board 16, and the lower part is used to press the first 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 silica gel button. The silica gel button is located below the P-gear button and can contact the contact on the lighting circuit board 16 when the P-gear button is pressed, send a P-gear signal to the gear shifter 30 below the rotary bracket 10, and simultaneously light up the light source 16a on the lighting circuit board 16. The light source 16a in the embodiment is an LED lamp, which is an RGB three-primary color LED. It can emit light of different colors or light effects according to the gear signal.
[0063] Please refer to Figure 8 The first bushing 13 is made of engineering plastic with self-lubricating properties (such as polyoxymethylene POM, polytetrafluoroethylene PTFE, etc.), which includes a first bushing body 131 and a plurality of skirts 132 extending radially outward from the outer edge of the top end of the first bushing body 131. Among them, the first bushing body 131 is in the shape of a hollow cylinder, and a plurality of bosses extending radially inward are distributed in the shaft hole of the middle part of the first bushing 13. Here, the boss is called the first boss 133, the first boss 133 extends along the axial direction of the first bushing body 131, and the cross section of the first boss 133 is in the shape of a circular arc. The surface of the circular arc can reduce the contact area between the first bushing 13 and the first shaft 27 arranged therein, and reduce the wear between the first bushing 13 and the first shaft 27 during the rotation of the light guide rotary wheel 20. The lower end surface of the first bushing body 131 is provided with a plurality of convex points 134, and the surfaces of the convex points 134 are in the shape of a circular arc, which can reduce the wear between the lower end surface of the first bushing 13 and the corresponding surface of the first shaft 27 during the rotation of the light guide rotary wheel 20. The skirt 132 at the top end of the first bushing 13 is in the shape of a fan ring and is distributed in the outer edge of the first bushing 13 in the circumferential direction. The skirt 132 is used to be buckled and fixed with the corresponding groove on the rotary bracket 10, so that the first bushing 13 does not rotate or move relative to the rotary bracket 10.
[0064] Please refer to Figures 9 to 11, the rotation shaft 20b is provided with a light inlet surface opposite to the light source 16a, a transmission surface for transmitting light, and a reflection surface for reflecting light to the rotation body 20a. The light emitted by the light source 16a can enter the rotation shaft 20b through the light inlet surface, and is transmitted through the transmission surface or reflected by the reflection surface to the rotation body 20a. Specifically, the rotation shaft 20b includes a first rotation shaft 27 and a second rotation shaft 28. The first rotation shaft 27 is close to the light source 16a, and the second rotation shaft 28 is away from the light source 16a. The first rotation shaft 27 is arranged in the first bushing 13 and is fixedly connected with the light guide rotation wheel 20 by interference fit or adhesive. The first rotation shaft 27 is made of transparent PC and has the functions of light guide, light collection and friction shaft. The first rotation shaft 27 includes a light guide part 271 close to the light source 16a, a first clamping part 272 and a first contact part 273 located at the middle part of the first rotation shaft 27, and a light transmission reflection part 274 away from the light source 16a. The light guide part 271 in the embodiment is a hollow cylindrical shape, and the bottom of the central hole is provided with a light collection surface 271a. The light collection surface 271a is the light inlet surface of the rotation shaft 20b, which is a convex lens surface for converging the conical light emitted by the LED and conducting downward. The first clamping part 272 in the embodiment is a flange protruding radially from other parts of the first rotation shaft 27, and the flange and the first rotation shaft part below it form a stepped surface to cooperate with the first shaft hole 24 arranged on the light guide rotation wheel 20 to position the first rotation shaft 27 in the first shaft hole 24 of the light guide rotation wheel 20. The first contact part 273 is located below the first clamping part 272, and the first contact part 273 in the embodiment is generally cylindrical, and the bottom edge includes a plurality of arc lines connected end to end. The diameter is equal to the diameter of the lower half of the first shaft hole 24, so that the first contact part 273 can be in contact with the inner surface of the first shaft hole 24 when the first rotation shaft 27 is placed in the first shaft hole 24, avoiding the first rotation shaft 27 from shaking in the first shaft hole 24. The light transmission reflection part 274 in the embodiment is provided with a transmission surface and a reflection surface, specifically including a first transmission surface 274a, a second transmission surface 274b, a third transmission surface 274c and a first reflection surface 274d. Among them, the first transmission surface 274a, the second transmission surface 274b and the first reflection surface 274d are multiple, and the third transmission surface 274c is one. The first transmission surface 274a is generally an isosceles trapezoidal plane, and the first transmission surface 274a extends inward and downward from the bottom end of the first contact part 273, and forms a first included angle with the axis of the first rotation shaft 27. The second transmission surface 274b is a quadrilateral, which extends outward and downward from the bottom end of the first transmission surface 274a. The second transmission surface 274b is slightly inclined outward relative to the axis of the first rotation shaft 27, and forms a second included angle with the axis of the first rotation shaft 27.The first reflecting surface 274d is an inverted isosceles trapezoidal plane, which is located below the second transmitting surface 274b, extends downward and inward from the bottom end of the second transmitting surface 274b, and forms a third included angle with the axis of the first rotating shaft 27. In this embodiment, the first included angle, the second included angle, and the third included angle are all acute angles, and the first included angle and the third included angle are both greater than the second included angle. The third transmitting surface 274c is a regular polygon, which is a regular decagon in this embodiment, that is, the corresponding first transmitting surface 274a, the second transmitting surface 274b, and the first reflecting surface 274d are all ten. It can be understood that in other embodiments of the present application, the third transmitting surface 274c can also be other regular polygons. The third transmitting surface 274c is located at the bottom of the first reflecting surface 274d, is arranged in a horizontal direction, and the outer contour edge of the third transmitting surface 274c coincides with the bottom edge of the first reflecting surface 274d.
[0065] Please refer to Figure 9 , Figure 12 and Figure 13The second rotating shaft 28 is also made of transparent PC, which comprises a reflecting part 281 at the upper part, a second clamping part 282 and a second contact part 283 at the middle part, and a supporting part 284 at the lower part. The reflecting part 281 in the embodiment is provided with reflecting surfaces, which specifically comprise second reflecting surfaces 281a and third reflecting surfaces 281b. The second reflecting surfaces 281a are horizontal surfaces at the top end of the second rotating shaft 28, which are regular polygons in shape. The third reflecting surfaces 281b are similar to fan ring shapes, but the top end of each third reflecting surface 281b is linear. Each third reflecting surface 281b is inclined downward and outward from the edge of the second reflecting surface 281a, and forms a fourth angle with the axis of the second rotating shaft 28. In the embodiment, the number of the second reflecting surfaces 281a and the third reflecting surfaces 281b is six, and the fourth angle is an acute angle. It can be understood that, in other embodiments of the application, the second reflecting surfaces 281a can not be provided, so that the top end of each third reflecting surface 281b intersects at a point. In such an embodiment, the third reflecting surface 281b is in the shape of a sector.
[0066] Please refer to Figure 9When the LED lamp works, the light emitted by the LED lamp is condensed by the light condensing surface 271a and then transmitted downward, and the light path of the transmitted light is divided into the following parts: a part of the light is transmitted through the first transmission surface 274a and then irradiates the inner cylindrical surface of the light guide rotating wheel 20; a part of the light irradiates the first reflection surface 274d and then is reflected to the second transmission surface 274b on the opposite side, and then is transmitted through the second transmission surface 274b and then transmitted to the inner cylindrical surface of the light guide rotating wheel 20; and another part of the light is directly transmitted through the third transmission surface 274c, irradiates the second reflection surface 281a or the third reflection surface 281b, and then is reflected to the inner cylindrical surface of the light guide rotating wheel 20. In this way, the light transmitted through different paths all passes through the light guide rotating wheel 20 and then is transmitted out from the diamond cutting surface on the surface of the light guide rotating wheel 20. Since the diamond cutting surfaces are designed to have an included angle, the light emitted from the surface of the light guide rotating wheel 20 can achieve a colorful effect. Since the light guide rotating wheel 20 can rotate, the color effect will change like a running light, and due to the existence of the angle, the color changing effect will also be accompanied.
[0067] It should be noted that not all types of light emitted by the LED lamp can be transmitted through the first transmission surface 274a and then irradiate the inner cylindrical surface of the light guide rotating wheel 20, and whether the light can be transmitted through the first transmission surface 274a and then irradiate the inner cylindrical surface of the light guide rotating wheel 20 depends on the coverage range of the light emitted by the LED lamp and the condensing degree of the light condensing surface 271a. If the coverage range of the light emitted by the LED lamp is small or the condensing degree of the light condensing surface 271a is high, no light will be transmitted through the first transmission surface 274a and then irradiate the inner cylindrical surface of the light guide rotating wheel 20. It should also be noted that the angles of the first transmission surface 274a, the second transmission surface 274b, the third transmission surface 274c, the first reflection surface 274d, the second reflection surface 281a and the third reflection surface 281b are specially designed according to the reflection and refraction laws, and all the transmitted light is perpendicular to the corresponding surface when it is transmitted out.
[0068] Please refer to Figure 2 and Figure 14The second bushing 14 is located below the second rotating shaft 28. The second bushing 14 comprises a disc-shaped bushing bottom 141 and a receiving portion 142 extending upward from a position close to the edge of the bushing bottom 141. The receiving portion 142 is a hollow cylinder, and a space for receiving the second rotating shaft 28 is formed in the receiving portion 142. The support portion 284 of the second rotating shaft 28 is located in the space, and the bushing bottom 141 of the second bushing 14 and the support portion 284 form a spherical surface friction pair. The receiving portion 142 of the second bushing 14 is also provided with a plurality of bosses extending inward in the radial direction. The bosses are referred to as second bosses 143. The second bosses 143 extend in the axial direction of the receiving portion 142, and the cross section of the second bosses 143 is arc-shaped. The arc-shaped surface can reduce the contact area between the second bushing 14 and the second rotating shaft 28 arranged therein, and reduce the wear between the second bushing 14 and the second rotating shaft 28 during the rotation of the light guide rotating wheel 20. Further, the edge of the bushing bottom 141 is provided with a plurality of elastic pieces 144 extending downward. The elastic pieces 144 abut against the second circuit board support 17 below the second bushing 14, and are used to eliminate the gap between the light guide rotating wheel 20 and the first rotating shaft 28 and the second rotating shaft 28 and to play a buffering role. In the present application, the rigidity of the elastic pieces 144 takes into account the weight of the crystal light guide rotating wheel 20 and the influence of the acceleration of the bumpy road. The structure of the second circuit board support 17 is similar to that of the first circuit board support 15, and will not be described here. The second circuit board support 17 is provided below with a relay circuit board 18, which mainly plays a role in relaying the electrical signal and realizing the transmission of the electrical signal.
[0069] The assembly process of the light guide rotating wheel type electronic gear shifting device of the present application is as follows:
[0070] First, the first rotating shaft 27 and the second rotating shaft 28 are respectively arranged in the first shaft hole 24 and the second shaft hole 25 of the light guide rotating wheel 20. The first rotating shaft 27 and the second rotating shaft 28 are fixed with the first shaft hole 24 and the second shaft hole 25 by interference fit or adhesive bonding. After assembly, the first rotating shaft 27 and the second rotating shaft 28 do not move relative to the first shaft hole 24 and the second shaft hole 25 in the working state.
[0071] Then, the light guide rotating wheel 20 is placed between the support upper portion 10a and the support lower portion 10b of the rotating wheel support 10, so that the first shaft hole 24 and the second shaft hole 25 of the light guide rotating wheel 20 are approximately aligned with the first bushing mounting hole 101 and the second bushing mounting hole 102 of the rotating wheel support 10.
[0072] Then, the first bushing 13 is loaded from the upper part of the runner support 10, so that the shaft hole of the first bushing 13 forms a rotating friction pair with the outer cylindrical surface of the first rotating shaft 27, the convex point 134 of the lower end surface forms a point-surface friction pair with the corresponding end surface of the first rotating shaft 27, the outer cylindrical surface of the first bushing 13 is transitionally fitted with the first bushing mounting hole 101 of the runner support 10, and the skirt 132 of the first bushing 13 is clamped into the groove on the runner support 10 to limit the rotation of the first bushing 13 in the rotating direction, prevent relative rotation between the first bushing 13 and the runner support 10, and at the same time, strengthen the connection stiffness of the first bushing 13 and the runner support 10, so that the light guide runner 20 feels more solid during operation.
[0073] Then, the first circuit board support 15 is placed above the first bushing 13, so that the lower end surface of the first circuit board support 15 abuts against the upper end surface of the first bushing 13 to position the first bushing 13 in the Z direction, and then the first circuit board support 15 is fixed to the runner support 10 by four screws.
[0074] Then, the lighting circuit board 16 is installed on the first circuit board support 15, so that the light source is aligned with the light collecting surface 271a of the first rotating shaft 24, and then the X direction, Y direction and axial rotation degrees of freedom of the lighting circuit board 16 are limited, and the lighting circuit board 16 is pre-pressed and fixed in the Z direction by the silica gel button, P block button and the like;
[0075] Then, the second bushing 14 and the second circuit board support 17 are sequentially loaded from the bottom of the runner support 10, and the assembly method and the role are similar to those of the first bushing 13 and the first circuit board support 15, which will not be described here. In particular, since the second bushing 14 is provided with four elastic sheets 144, it will be in a pre-pressed state after assembly. When the bushing and rotating shaft are worn after a period of use, the elastic sheet 144 will release part of the deformation to supplement the gap caused by wear, so that the fit between the bushing and the rotating shaft is in a 0 gap state, and there will be no impact noise when passing through a bumpy road.
[0076] Through the structure design of the light guide rotating wheel and the electronic gear shifting device, when needed, the driver can hold the rotating wheel support and use fingers to rotate the light guide rotating wheel, so that the light guide rotating wheel can rotate freely, and in addition to realizing the gear shifting function, the light guide rotating wheel can also realize the "playing" and "recreation" functions, and achieve the "decompression" purpose; and the light source is arranged above the light guide rotating wheel, and through the transparency of the crystal and the "diamond" cutting surface, and the rotation characteristics of the light guide rotating wheel, colorful and "shining" effects can be presented, and the scientific and technological feeling of the electronic gear shifting device is improved; the light guide rotating wheel of the application is designed with a specific rotating pair, the crystal material is not directly used as a friction pair, the rotating pair is composed of a bushing made of a self-lubricating material and a rotating shaft, the rotating shaft is made of transparent plastic with certain friction performance, and the rotating shaft serves as a rotating pair and a light guide strip; the light path transmission is considered when the rotating shaft is designed, and the rotating shaft has the functions of light collection, reflection and refraction, and the rotating shaft rotates with the light guide rotating wheel, the cutting surface on the rotating shaft rotates with the light guide rotating wheel in the process of rotating the light guide rotating wheel, and the light can produce dynamic effects; in addition, considering the machining error in the cutting process of the crystal, a spring plate is designed on the second bushing, and the spring plate is used to absorb the gap caused by the machining error, assembly error and durable wear, so that the light guide rotating wheel always maintains a smooth rotating state; the rotating wheel support is formed by metal die casting and then machined, the strength and rigidity of the rotating wheel support can be ensured by using metal material, and the positioning accuracy of the rotating wheel support can be ensured by using machining.
[0077] The above merely describes the specific implementation of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, and all of them should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
