Description

Technical Field

[0001] This utility model relates to a switch control assembly for a vehicle and a vehicle having said switch control assembly. Background Technology

[0002] Currently, as vehicle users increasingly demand greater driving comfort and convenience, the functions of infotainment and driver assistance systems in vehicles are constantly expanding, requiring more and more control devices to manage these functions. However, the limited internal structure of a vehicle necessitates a rational and compact arrangement of these control devices. Simultaneously, to minimize interference with the driver's activities, it is desirable to assist the driver in performing operations correctly without affecting their attention. However, existing technologies often fail to meet these requirements. Drivers often lack intuitive feedback during the operation of switch control components and frequently need to pay extra attention to the actions, potentially leading to risks to driving safety. Utility Model Content

[0003] In view of the above-mentioned drawbacks, the technical problem to be solved by this utility model is how to provide a reliable and user-friendly switch control component.

[0004] To solve the aforementioned technical problem, this utility model relates to a switch control assembly for a vehicle. The switch control assembly includes a roller unit, which comprises: a roller rotatable along a rotation axis, the roller being hollow and cylindrical in shape and including a first end and a second end opposite to each other along the rotation axis; a rotating shaft fixedly connected to the first end of the roller and including a circumferential portion and an end plate; a fixed shaft rotatably connected to the second end of the roller; a hand-feed wheel torsionally connected to the fixed shaft and translatably arranged between the rotating shaft and the fixed shaft along the rotation axis; and a spring element pre-tensioned between the fixed shaft and the hand-feed wheel. The side of the circumferential portion of the rotating shaft facing the hand-feed wheel includes a corrugated portion, and the hand-feed wheel always abuts against the corrugated portion under the pre-tension force of the spring element, thereby causing the hand-feed wheel to reciprocate in the direction of the rotation axis during the rotation of the roller around the rotation axis.

[0005] According to this invention, during the rotation of the roller, the rotating shaft rotates together with the roller around the axis of rotation, while the fixed shaft does not rotate, thus causing relative rotation between the rotating shaft and the fixed shaft. Because the hand-feed wheel is torsionally connected to the fixed shaft, it also rotates relative to the rotating shaft. Simultaneously, under the preload of the spring, the hand-feed wheel always rests against the corrugated part of the rotating shaft, causing it to reciprocate in the direction of the axis of rotation and vibrate accordingly. This vibration provides the user with intuitive and clear tactile feedback, preventing the user from focusing excessively on the operation process and improving driving safety.

[0006] In one embodiment, the feel wheel includes at least one protruding finger. At least two protruding fingers may be provided, for example, three protruding fingers. Providing more than one protruding finger allows for more reliable contact between the feel wheel and the corrugated portion of the shaft.

[0007] In one embodiment, the corrugated portion includes alternating circumferential crests and troughs, wherein the extension lines of the crests and troughs extend radially. The number of crests and troughs can be adapted to the level of the function to be set or invoked by the switch control component.

[0012] In one embodiment, the feel wheel includes a feel wheel body, which is hollowly cylindrical and fitted onto the fixed shaft body. The fixed shaft body includes a fixed shaft retaining pin extending along the direction of the rotation axis, and the feel wheel includes a feel wheel retaining groove extending along the direction of the rotation axis. The fixed shaft retaining pin is movably embedded in the feel wheel retaining groove along the direction of the rotation axis.

[0013] In one embodiment, the feel wheel body includes a crossbeam, wherein one end of the spring abuts against the fixed shaft body and the other end abuts against the crossbeam.

[0014] In one embodiment, the fixed shaft body further includes opposing fixed shaft long slots, wherein the fixed shaft long slots extend to the free end of the fixed shaft body, and the crossbeam is engaged in the fixed shaft long slots.

[0015] In one embodiment, the switch control assembly further includes a circuit board unit, wherein the circuit board unit includes an optical sensor, and the roller unit further includes a grating wheel that is drivenly connected to the rotating shaft, wherein the grating wheel cooperates with the optical sensor to rotate the grating wheel during the rotation of the roller around the rotation axis, thereby triggering the optical sensor.

[0016] In one embodiment, the rotating shaft is connected to the grating wheel gear. In some feasible embodiments, the grating wheel can directly mesh with the output gear formed at the free end of the rotating shaft; in other feasible embodiments, the grating wheel can also mesh with the output gear of the rotating shaft by means of an idler gear.

[0017] In one embodiment, the roller unit further includes a roller bracket, the roller bracket including a bracket body and a first support end and a second support end opposite to each other along the direction of the rotation axis, wherein the rotating shaft is rotatably supported at the first support end, and the fixed shaft is fixedly supported at the second support end.

[0018] In one embodiment, the roller bracket is movably arranged on the circuit board unit, wherein the bottom of the roller bracket includes at least one pressing contact, the circuit board unit includes a circuit board with at least one switch contact and a movable contact associated with the switch contact, the movable contact being made of conductive rubber, wherein during the pressing of the roller bracket, the pressing contact pushes the movable contact, thereby causing the movable contact to press the switch contact.

[0019] In one embodiment, the switch control assembly further includes a housing unit in which the roller unit is disposed, wherein the support body includes at least one guide rib, the housing unit includes at least one guide rail, the guide rib being slidably fitted into the guide rail to guide the movement of the roller support relative to the circuit board unit.

[0020] This invention relates to a switch control component for vehicles. During the rotation of the roller, the tactile feel wheel reciprocates along the axis of rotation and vibrates accordingly. This vibration provides the user with intuitive and clear tactile feedback, preventing the user from focusing excessively on the operation process and improving driving safety.

[0021] To address the aforementioned technical problem, this utility model also relates to a vehicle comprising the aforementioned switch control assembly.

Detailed Implementation

[0049] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] The term "one embodiment" or "implementation" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "top," "bottom," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0051] like Figure 1 A perspective view of a switch control assembly according to one embodiment of the present invention is shown schematically. Figure 2 schematically shown Figure 1 The diagram shows a 3D view of the switch control assembly after the top cover has been removed. Figure 3 The diagram schematically shows a longitudinal perspective sectional view of the switch control assembly. This switch control assembly can be applied to the interior of a vehicle to adjust and set vehicle functions through various control modes.

[0052] The switch control assembly includes a housing unit 1, a roller unit 2, and a circuit board unit 3.

[0053] The housing unit 1 includes at least a bottom shell 10 and a top cover 11, wherein the top cover 11 is movably disposed on the bottom shell 10. The top cover 11 and the bottom shell 10 define an internal space for at least partially accommodating the roller unit 2 and the circuit board unit 3. Figure 4 , Figure 5 As shown, the bottom shell 10 includes a roller receiving portion 10a for accommodating the roller unit 2. The top cover 11 has an opening in the middle to expose the components of the roller unit 2. The circuit board unit 3 is fixedly arranged in the bottom shell 10, and the roller unit 2 is arranged above the circuit board unit 3.

[0054] This control switch component can operate in scrolling mode. For example... Figures 6 to 20 As shown, the roller unit 2 includes a roller bracket 20 and a roller 21 supported on the roller bracket 20. The roller 21 can rotate around the rotation axis x under the operation of the user. The rotation of the roller 21 will trigger a corresponding output signal, which is processed by the circuit board unit 3 to trigger the corresponding function.

[0055] As an alternative or supplement, the control switch assembly can also operate in a press mode. In this embodiment, the roller unit 2 is movably arranged on the circuit board unit 3. When the user presses down on the roller 21, the roller unit 2 moves downward as a whole to trigger the corresponding switch contact on the circuit board unit 3.

[0056] especially Figure 8 As shown, the roller assembly includes a roller 21, a rotating shaft 22, a fixed shaft 23, a touch wheel 24, and a spring 25. In... Figure 7 In the assembled state of the roller assembly shown, one end of roller 21 is fixedly connected to shaft 22, and the other end of roller 21 is rotatably connected to fixed shaft 23. Shaft 22 is rotatably supported on roller bracket 20, and fixed shaft 23 is fixedly supported on roller bracket 20. Thus, when roller 21 rotates, shaft 22 rotates along with roller 21 around the rotation axis x, while fixed shaft 23 does not rotate, thereby achieving relative rotation between shaft 22 and fixed shaft 23.

[0057] like Figure 9As shown, the roller 21 is generally hollow and cylindrical in shape, and includes a first end and a second end opposite to each other in the direction of extension of the rotation axis x. The roller 21 is fixedly connected to a pivot 22 at its first end and rotatably connected to the fixed pivot 23 at its second end. The roller 21 includes a large number of protrusions 210 disposed on its circumferential outer side. These protrusions 210 are arranged densely adjacent to each other, thereby increasing the roughness of the outer surface of the roller 21 and providing greater friction between the user's hand and the roller 21, which facilitates reliable operation of the roller 21 by the user. The inner wall of the roller 21 has at least one locating pin 211 and at least one roller locking groove 212. The locating pin 211 extends along the direction of the rotation axis x and protrudes radially toward the center. The roller locking groove 212 protrudes into the inner wall of the roller 21.

[0058] like Figure 10 As shown, the rotating shaft 22 includes a circumferential portion 220 and a shaft end plate 221 connected to the circumferential portion 220. An output shaft 222 is fixedly disposed on the outward-facing side of the shaft end plate 221, and an output gear 223 is fixedly connected to the free end of the output shaft 222. The circumferential portion 220 includes a shaft positioning groove 224 and a radially outward-protruding shaft latch 225. Figure 11 As shown, a corrugated portion 226 extending continuously in the circumferential direction is provided on the side of the circumferential portion 220 opposite to the output gear 223. The corrugated portion 226 has alternating crests and troughs, and the extension lines of the crests and troughs generally extend radially outward from the center.

[0059] like Figure 12 The fixed shaft 23 includes a fixed shaft body 230, a fixed end 231, a fixed flange 232 near the fixed end 231, and a fixed shaft elongated groove 233 opposite to the fixed end 231. In this embodiment, the fixed shaft 23 includes two mutually aligned fixed shaft elongated grooves 233 that extend to the free end of the fixed shaft body 230, thereby forming a bayonet on the side of the fixed shaft body 230 opposite to the fixed end 231. Furthermore, at least one fixed shaft locking pin 234 is provided on the circumferentially outer side of the fixed shaft body 230. The fixed flange 232 protrudes radially outward from the fixed shaft body 230 and has a circular outer contour.

[0060] like Figure 13 As shown, the touch wheel 24 includes a hollow cylindrical touch wheel body 240. At least one axially protruding finger 241 is provided at the edge of the touch wheel body 240. A crossbeam 242 is fixedly provided on the inner wall of the touch wheel body 240. An open-end touch wheel groove 243 is provided on the side of the touch wheel body 240 opposite to the finger 241.

[0061] like Figure 8 As shown, one end of the spring 25 acts on the fixed shaft 23, and the other end acts on the hand feel wheel 24. For this purpose, one end of the spring 25 abuts against the bottom of the fixed shaft body 230, and the other end abuts against the crossbeam 242 of the hand feel wheel 24.

[0062] When assembling the roller assembly, first insert the spring 25 into the fixed shaft body 230 of the fixed shaft 23, and then slip the hand-feel wheel 24 onto the fixed shaft body 230 from the side with the fixed shaft groove 233. Figure 15 As shown. In this state, the fixed shaft pin 234 of the fixed shaft 23 is engaged in the feel wheel slot 243 of the feel wheel 24, and the crossbeam 242 of the feel wheel 24 is engaged in the fixed shaft groove 233 of the fixed shaft 23. This prevents the feel wheel 24 from rotating relative to the fixed shaft 23 about the rotation axis x. Furthermore, since the axial length of the fixed shaft pin 234 is less than the length of the feel wheel slot 243, the feel wheel 24 can be translatably fitted onto the fixed shaft 23.

[0063] Subsequently, the fixed shaft 23, together with the feel wheel 24, is inserted into the roller 21 from one side of the first end of the roller 21, wherein the fixed flange 232 of the fixed shaft 23 abuts against the second end of the roller 21.

[0064] Next, the rotating shaft 22 is inserted into the roller 21 from one side of the first end of the roller 21, wherein the rotating shaft end plate 221 of the rotating shaft 22 closes the end face of the roller 21. In this state, the locating pin 211 of the roller 21 is fitted into the rotating shaft locating groove 224 of the rotating shaft 22, as shown. Figure 14 As shown, the shaft snap 225 of the rotating shaft 22 is engaged in the roller snap groove 212 of the roller 21. This reliably prevents relative rotation and axial displacement between the roller 21 and the rotating shaft 22.

[0065] Combination Figure 16 and Figure 17 As shown, in the assembled state of the roller assembly, one end of the roller 21 is torsionally connected to the rotating shaft 22, and the other end of the roller 21 is rotatably connected to the fixed shaft 23. The hand-feed wheel 24 is arranged translatably between the rotating shaft 22 and the fixed shaft 23 along the extension direction of the rotation axis x, that is, along the axial direction, and the protruding finger portion 241 of the hand-feed wheel 24 abuts against the corrugated portion 226 of the rotating shaft 22 under the preload of the spring member 25.

[0066] Figure 19The roller bracket 20 is schematically shown. The roller bracket 20 includes a bracket body 200, a first support end 201 and a second support end 202 axially opposed to each other. In this embodiment, the rotating shaft 22 is rotatably supported at the first support end 201 by its output shaft 222; the fixed end 231 of the fixed shaft 23 has a non-circular outer contour, and the second support end 202 of the roller bracket 20 is shaped to fit the fixed end 231, wherein the fixed end 231 is fitted into the second support end 202, thereby fixing the fixed shaft 23 to the roller bracket 20.

[0067] The rotation of roller 21 around the rotation axis x drives the rotating shaft 22, which is fixedly connected to it to resist torsion, to rotate around the rotation axis x together, while the fixed shaft 23 remains stationary. The touch wheel 24 does not rotate around the rotation axis x. During this process, because the protruding finger portion 241 of the touch wheel 24 is always pressed against the corrugated portion 226 of the rotating shaft 22 under the action of the spring member 25, when the rotating shaft 22 rotates with the roller 21, the crests and troughs of the corrugated portion 226 successively pass over the protruding finger portion 241 of the touch wheel 24, causing the touch wheel 24 to reciprocate axially. The resulting vibration is transmitted to the user's hand, allowing the user to clearly and intuitively perceive tactile feedback.

[0068] For example, in this embodiment, the corrugated portion 226 is configured with 12 sets of adjacent peaks and troughs to correspond to, for example, 12 levels of volume setting. Of course, in embodiments not shown, the corrugated portion 226 can be configured densely or sparsely as needed to correspond to, for example, volume adjustment, radio frequency bands, music playback selection, light level adjustment, etc.

[0069] like Figure 18 As shown, the roller unit 2 also includes an idler wheel 26 and a grating wheel 27. The idler wheel 26 and grating wheel 27 are also rotatably supported at the roller bracket 20. The idler wheel 26 meshes with the output gear 223 of the rotating shaft 22; the grating wheel 27 includes a driven gear 271, a driven shaft 272 fixedly connected to the driven gear 271, and an impeller 273. The driven gear 271 meshes with the idler wheel 26, and the impeller 273 cooperates with the optical sensor 32 to trigger a corresponding output signal.

[0070] In an embodiment not shown, the idler gear 26 may be omitted, allowing the driven gear 271 of the grating gear 27 to directly mesh with the output gear 223.

[0071] like Figures 21 to 23As shown, the circuit board unit 3 includes a circuit board 30 and multiple switch contacts 31 and other electrical components arranged on the circuit board 30, which is covered with conductive rubber. For example, in this embodiment, two switch contacts 31 and an optical sensor 32 are provided on the circuit board 30. The circuit board unit 3 also includes movable contacts 33 associated with the switch contacts 31. These movable contacts 33 are made of an elastic conductive material and are respectively arranged above each switch contact 31. For example, in this embodiment, the movable contacts 33 are constructed as elastic pads made of conductive rubber. The optical sensor 32 has two opposing arms, one arm of which is provided with a light source and the other arm of which is provided with a detector, and the light beam emitted by the light source can be detected by the detector. The impeller 273 of the grating wheel 27 is arranged between the two arms. When the impeller 273 rotates, the impeller 273 intermittently blocks the light beam transmitted between the two arms of the optical sensor 32, thereby alternately allowing or preventing the light beam emitted by the light source from being detected by the detector, thereby forming an output signal, such as an I / O digital signal.

[0072] like Figure 19 , Figure 20 and Figure 24 As shown, the roller bracket 20 has at least one guide rib 203 and at least one hook 204 on the side wall of its bracket body 200; at least one pressing contact 205 is included at the bottom of the bracket body 200. The downward pressure of the roller 21 causes the roller bracket 20 to move downwards together, thereby bringing the pressing contact 205 into contact with the movable contact 33 of the circuit board unit 3, causing the movable contact 33 to move downwards to trigger the switch contact 31 on the circuit board 30. At least one guide rail 101 and at least one stop 102 are provided at the edge of the roller receiving portion 10a of the bottom housing 10. The guide rib 203 of the roller bracket 20 is slidably fitted into the guide rail 101 of the bottom housing 10, thereby accurately guiding the movement of the roller bracket 20 in the height direction. The stop 102 is constructed as a bottom-closed groove, and the hook 204 of the roller bracket 20 can abut against the bottom of the stop 102. Thus, the downward stroke of the roller bracket 20 is limited by the cooperation between the hook 204 and the stop portion 102. The movable contact 33 of the circuit board unit 3 is elastic, so when the user releases the roller 21 to release the pressure, the roller bracket 20 is reset upward by the restoring force of the movable contact 33, so that the movable contact 33 is separated from the switch contact 31.

[0073] In the scrolling mode of this switch control component, the user applies rotational force to the circumferential surface of the roller 21, causing the roller 21 and the rotating shaft 22 to rotate together around the rotation axis x, thereby driving the grating wheel 27 to rotate and trigger the corresponding output signal, while the fixed shaft 23 remains stationary. During this process, the tactile wheel 24 reciprocates along the extension direction of the rotation axis x and repeatedly collides with the corrugated portion 226 of the rotating shaft 22. The resulting vibration is transmitted to the user's hand, allowing the user to clearly and intuitively perceive tactile feedback.

[0074] In the press mode of the switch control component, the user presses the circumferential surface of the roller 21, thereby driving the roller bracket 20 to move downward, and presses the movable contact 33 by pressing the contact 205, so that the movable contact 33 contacts the switch contact 31 to trigger the corresponding output signal.
