[0003] This invention generally relates to gear shifter assemblies. More specifically, the invention discloses a rolling gear shifter adapted to be mounted in various locations within a vehicle interior (steering wheel, lever, dashboard, IP, etc.) according to any desired orientation and providing 360-degree rotational capability via a roller or knob component having a knurled annular edge for operator engagement and incorporating a separate end-face stop profile, which further defines alternating peaks and troughs that engage with a plurality of biased pawls supported within a gear shifter housing, thereby allowing the operator to roll through various gears. The assembly also provides a return to parking position from any gear upon command, as well as parking and neutral locking functions. Background Technology

[0008] Other references include US10,780,909, which teaches an interactive user interface for a steering wheel. The user interface is located on one or more portions of the steering wheel and recognizes hand gestures made by the user on that interface. The user interface allows guidance of a set of controls associated with menus provided through the user interface based on the recognized hand gestures. Summary of the Invention

[0009] This invention discloses a scroll gear shifter assembly, which may be applied, for example, but not limited to, to any of a gear shifter, windshield wiper controller, volume controller, or dimmer controller. The scroll gear shifter may be located in any vehicle interior location, not limited to the steering wheel, lever, dashboard, windshield wiper controller, volume controller, or dimmer controller, or other locations within the vehicle's instrument panel.

[0010] In any implementation, the assembly includes a housing that rotatably supports a roller having a knurled outer edge accessible to a vehicle operator. The roller also includes annular stop profiles defined on one or both of its oppositely arranged end faces, each stop profile exhibiting alternating peaks and grooves. A magnetic element is incorporated into the rotatable shaft support end face of the roller, such that the magnetic element is positioned close to a sensor mounted within the housing on a printed circuit board assembly (PCBA). Rotation of the roller displaces the magnetic element relative to the sensor, allowing the PCBA to indicate any gear shifts or (in alternative applications) other changes in position / condition.

[0011] The display component is mounted close to the PCBA and may include any of thin-film transistors (TFTs), organic light-emitting diodes (OLEDs), or segmented displays. In a first embodiment, at least one pawl is supported within a housing and spring-loaded to bias against each of the annular stop profiles, such that when an operator actuates the roller, the pawl shifts relative to the profile, thereby incrementally rotating the roller. A magnetic element rotates relative to a PCBA sensor to electronically indicate gear shifting via a processor associated with the PCBA. Other variations of the spring-loaded pawl include wave springs with rounded profiles, used to bias against alternating stop peaks and grooves to provide the desired tactile / sensory effect between successive gears or positions.

[0012] The housing also includes housings of various shapes that can be fitted into desired vehicle locations using an attachable bottom cover. Any arrangement of plates or bushings can be provided to rotatably support the rollers within the housing and to bias the pawls or wave springs. Other features include a pair of windows defined in the upper surface of the main housing for housing each of the rollers and display components.

[0013] The return-to-park function provides the PCBA with the ability to reset the shifter to the parking position in response to a determined external input. Both parking lock and neutral lock functions are provided to prevent shifting caused by rotation of the rollers, unless the PCBA determines that the necessary conditions exist for providing electronic shifting.

[0014] In another variation, the rolling shifter assembly can be integrated into the steering wheel, such that the rotation of the steering wheel is counteracted by the simultaneous rotation of the assembly, keeping the assembly upright relative to the operator for easy access. This assembly can be mechanically interconnected with the central gear in any of the gear trains or pulley systems, or with the steering wheel support.

[0015] In the third electric drive option, a sensor arrangement is employed to convert the rotation of the steering wheel into a corresponding rotation of a rotary switching element. In a further, non-limiting alternative, an electronically adjustable sensor system is provided, for example, including a steering wheel angle sensor, to continuously reorient the rolling assembly to an upright position. Other variations include alternative mechanical or electrical options for physically reorienting the combined display and rolling shifter, and facilitate the reorientation of the combined display portion of the rolling shifter assembly, in which case, any type of capacitive or other touchscreen display positioned on the steering wheel.

Detailed Implementation

[0060] Referring to the accompanying drawings, this invention discloses several variations of a rolling vehicle gear shifter assembly, such as... Figure 2 , Figure 27 , Figure 34 and Figure 41Each figure illustrates this, and the scroll gear shifter assembly is suitable for installation in various locations within the vehicle interior; similarly, the scroll gear shifter assembly includes any of the following: console, dashboard, steering wheel, or steering wheel lever. As previously stated, the scroll gear shifter is suitable for installation within the vehicle interior in any desired orientation and provides the operator with the ability to scroll 360 degrees through various gears. The assembly also provides the ability to return to park from any gear upon command, as well as parking and neutral locking functions.

[0061] As will be further described in each of the following embodiments, the scroll shifter assembly provides a variety of functions, including providing an operator interface for gear selection, tactile feedback to the operator during gear shifting, and providing the operator with multiple stable positions (fixed positions for each gear). Other features include the operator being able to touch the surface of the rollers while moving forward through the gears. Other functions include the ability to return to parking from any gear upon command, electronic parking or neutral locking, and an enhanced display option with gear indication. Additional features include the ability to orient the assembly for up / down or left / right scrolling to select gears, and design flexibility to reduce size for integration into various locations, including the steering wheel, steering wheel lever, and any other instrument panel or dashboard location.

[0062] First refer to Figure 1 An exploded view of a rolling gear shifter assembly according to a non-limiting embodiment is shown, and the rolling gear shifter assembly is generally composed of Figure 2 The component indicated by 10 in the perspective view is represented. A main housing 12 is provided, which can be made of any suitable material, not limited to finished metals and / or rigid plastic composites. The housing 12 shown presents a three-dimensional rectangular interior, as depicted in the alternative embodiment, which includes any other encapsulation space reconfigured to define the interior for supporting the various components of the rotary knob assembly.

[0063] The bottom cover, shown as 14, is secured to the bottom edge 15 of the opening of the main housing 12 via a pair of mating screw receiving portions, represented by a pair of ear-like parts 16 / 18 extending from the lower corner of the housing 14, and aligned with a pair of collars 20 / 22 arranged at the edge or corner of the bottom cover 14. Screws 20 are provided for securing the housing 12 and the bottom cover 14 together.

[0064] A pair of window-shaped, such as rectangular, openings are formed within the top surface of the main housing 12, and the openings are indicated by interconnected edge edges 24 and 26. The window-shaped openings expose each of the knurled outer annular edge of the roller (generally shown as 28) and the display component 30, which, as will be further described, includes any TFT / OLED or segmented display connected to the PCBA. The window-shaped openings may include separate bezel displays, shown as 32 and 34, which are positioned above the edges of the defining edges 24 and 26 formed within the housing body 12. The main housing 12 also includes a recessed side location 36 through which external wiring or cable connectors (e.g., which may be associated with a return-to-park function) extend into the internal PCBA (described below as 66). Other features include an elongated positioning protrusion 38 located inside the bottom cover 14, which provides positioning for and supports the plates 50 and 52, as further described below.

[0065] Roller 28 includes each of an extension shaft 40 and an annular disc-shaped protrusion 42, the annular disc-shaped protrusion 42 corresponding to the shape of a wheel, and the disc-shaped protrusion also exhibits a knurled pattern having alternating peaks 44 and valleys 46 (see FIG. 5) arranged around the disc-shaped protrusion in an outward-facing annular circumferential portion. The roller also includes a separate stop pattern 48 (see FIG. 5). Figure 10A and Figure 10B The stop pattern is constructed on the upper annular and laterally extending surface of the disc-shaped protrusion 42. As best shown in FIG5, the stop pattern 48 includes alternating peaks and valleys, which provide a desired tactile / perceptible effect when the alternating peaks and valleys are contacted by the spring-biased pawl 62 during the rotation of the roller 42.

[0066] Inside the main housing 12 are mounted a pair of first (or left) internal support plates 50 and a second (or right) internal support plate 52, each including opposing annular grooves defining collars (see plates 50 / 52 shown at 54 and 56 respectively) for rotatably accommodating opposite ends of the roller shaft 40. The left support plate 50 may include an upper seating position 55 for supporting the disc or dish display component 30 and aligning it with a corresponding window-shaped defining bezel 34. At the shaft support position on the opposite end of the roller 28 and positioned relative to plates 54 / 56 are a pair of annular ball support members shown at 58 and 69 to allow the roller 28 to rotate about the shaft 40. Additional fastener screws 20 are also depicted in the figures, securing the PCBA 66 to rearwardly projecting support positions 51 and 53 of the left inner support plate 50.

[0067] A pair of pawl elements 62 and corresponding stop (or compression) springs 64 are supported at additional seating positions 61 and 63 on the right plate 52 such that the pawl elements are biased against the peaks and valleys (or grooves) of the stop profile 48, thereby providing a tactile interface with the operator. A PCBA (Printed Circuit Board Assembly) 66 is provided and mounted to the left plate 50. A receiving connector 67 is formed on the rear surface of the PCBA 66 for engagement with a separate vehicle connector (not shown).

[0068] The roller shaft 40 is inserted into the left plate 50 through the hole 65, such that the end-supported magnetic element 68 (which can be mounted or molded into the extended shaft end position 70) is adapted to rotate with the shaft and with the sensor 72 (see) located on the surface of the PCBA 66. Figure 8 Adjacent to this, the sensor is connected to the microprocessor component of the PCBA to electronically indicate changes in gear position. In an alternative variant, the magnetic element 68 can be repositioned from the roller to another position within the assembly and can be actuated by either a gear train and / or a pulley system that interconnects the displacement (rotation) of the roller and the magnetic element.

[0069] Figure 2 yes Figure 1 The diagram shows an assembled perspective view of the rolling shifter assembly, depicting the exposed portion of the annular wavy surface of the rolling wheel 42 protruding through the selected window 24 of the main housing 12, and the display 30 (TFT / OLED or segmented display) also protruding through the second annular edge defining the window 26. Figure 3 yes Figure 2 The cross-sectional view depicts the combination of roller 42 with integral shaft 40, support bearings 58 / 60 and mounting plates 50 and 52 with housing 12 and display component 30.

[0070] Figure 4 is a further perspective view of the internal components of the rolling shifter, with the housing removed for clarity, including the orientation of components such as the rollers 42, the clamping inner plates 50 / 52, and the display. Additional mounting fasteners, also shown at 20, are provided for securing the components together.

[0071] Figure 5 is an enlarged perspective view of roller 42, depicting a non-limiting representation of the external annular knurled pattern (alternating ridges 44 and recesses 46) for engagement by the user's (operator's) thumb or fingers. Combined, the stop profiles 48 arranged on the upper end face have alternating peaks / ridges and valleys / grooves, against which a spring-biased pawl 62 makes contact to provide the desired tactile effect.

[0072] Figure 6 is a transparent partial view of roller 42, which has a stop pawl 62 and a return compression spring 64. The return compression spring 64 biases the pawl against a stop profile, thereby changing the compressive force applied against the roller 42 as the pawl 62 gradually shifts between the peak and groove constructed within the stop profile in response to the rotation of the roller. This results in the pawl 62 (located within a receiving portion constructed within the right plate 52 and positioned near the central rotatable support recess 56) applying a continuous biasing force to the stop profile of the roller, thereby providing a tactile (perceptible) rotation adjustment interface by compressing the pawl 62 against the compression spring 64 due to the peak.

[0073] Figure 7 Is with Figure 2 The diagrams are basically repeating, and Figure 8 Similarly with Figure 3 The diagrams are basically repeating, and Figure 7 The characteristics of the roller 42 and the end support magnet 68 are better depicted. The end support magnet 68, when rotated to be close to the sensor 72 mounted on the PCBA, sends a shift status signal to the relevant processor. As described above, when the roller rotates as indicated by the double-headed arrow 65, the shaft end support magnet 68 rotates together (see...). Figure 8 The sensor, which is arranged adjacent to the PCBA, is further rotated by arrow 76 to indicate electronic shifting.

[0074] Figure 9 The non-restrictive outer annular pattern associated with the roller is further depicted, similarly including alternating and angled knurled protrusions 44 and recesses 46. A side-arranged stop profile 48 is also depicted, constructed on the outer side of the wheel 42 for biasing the spring-loaded pawl 62.

[0075] As described, and as the roller 42 rotates, the stop profile 48 engages with the stop pawl 62 supported by the compression spring 64. In this way, and as the roller rotates to cause the pawl 62 to shift in an offset manner between the alternating peaks and grooves of the stop profile 48, the spring 64 is compressed and the operator can easily feel (tactilely or perceptibly) the associated effort to compress the spring.

[0076] The determined force is also defined by each of the following: the height of the stop peak, the corresponding depth of the stop grooves alternating with the peak, the defined angle between the stops, the surface shape / roughness or material construction of the stop pawl and stop profile, and the spring compression rate. The gear selection also depends on the angular distance between the alternating grooves, which corresponds to the rotation of the magnetic component relative to the sensor mounted on the PCBA.

[0077] Continue to Figure 10A and Figure 10BThe diagram shows a pair of views illustrating an electronic return to the parking position, where the shifter is configured to return to the parking position from any gear when commanded by the processor. This is typically generated by an external sensor (not shown) and can be associated, for example, with any of a variety of functions, such as determining whether a door is open. When a remote sensor (e.g., interconnected to the PCBA via one or more extension cables) indicates the presence of external conditions inconsistent with any gear position other than parking, the PCBA processor receives this indication and, in turn, electronically shifts the shifter from the non-parking position (see again). Figure 10B The driving position in the system is reset to the parking position (see again). Figure 10A ).

[0078] This application also provides each of a parking lock function and a neutral lock function. Specifically, the structure and function of the parking lock function and the neutral lock function of this design will now be described, and this design provides an operator locking function in each of the parking shifter position and the neutral shifter position to prevent restraint of the motor components in either engagement position, and to ensure that certain conditions are met to disengage the shifter from either the parking position or the neutral position.

[0079] Figure 11A and Figure 11B A pair of views are also shown, respectively, of the electronic parking lock state or the neutral lock state associated with the roll shifter. (Non-limitingly, the parking lock...) Figure 11A This mechanism works as follows: The operator must first depress the vehicle's brake pedal (not shown) to actuate the rollers and shift the vehicle from the parking position. Otherwise, if the brake pedal is not depressed first, the rollers may rotate, but the vehicle will remain parked until the conditions are met and the PCBA indicates a shift. Also, refer to... Figure 11B The neutral lock function causes the shifter to remain in neutral according to the operator's command, allowing the roller to rotate without changing the gear, until the conditions required by the PCBA are met.

[0080] Figure 12 shows a graphics display component associated with the shifter assembly and including any TFT / OLED or segmented display variants (also in...). Figure 1 A variation of the (shown at 30') is illustrated in Figure 13. Figure 13 depicts a plan view of the relevant graphic display at 30', illustrating different depictions, such as those that can be completed without etching or other custom processing. In each case, custom descriptions of multiple shifter positions PRNDM or PRNDS are provided, and any pixelated or segmented image can be provided on non-etched parts (e.g., thin-film transistor or organic LED displays).

[0081] This invention discloses a display component 30, not limited to any improved graphic display for integration into a shifter assembly to provide identification of shifter position. The improved display can again incorporate any of the variations of thin-film display (TFT), transistor LCD, or organic LED (OLED) display, and allows for the creation of any representation within the display surface geometry, not limited to color, pattern, or intensity (again, for example, not limited to a circular display in a rotary shifter or a rectangular display associated with a linear door shifter, etc.). This invention also allows for the use of a clean display surface (without any painting or etching associated with the known shifter position indicator PNRD) and is limited only by the operating software communicating from the associated circuit board and microcontroller.

[0082] In each variant, the display housing is positioned away from the PCBA 66 and can incorporate multiple LEDs or suitable lighting components. End connectors 74 provide LED backlight power for the segmented display variant. Connecting wires 76 / 78 are also shown, each extending from the surface display housing to connect to the PCBA. In one variant, the surface display is generally configured without any specific etched or painted markings and its color and intensity can be modified based on input received from the PCBA to achieve the desired lighting scheme.

[0083] The connector (strip shape) 80 communicates the LCD (liquid crystal) segments housed in the display 30 (not shown) to the PCBA, and provides LED power for TFT and OLED display versions. It also communicates the individual lines within the strip lighting element to selected segments on the display surface. In this way, and based on the collection of various inputs from the main microcontroller located on the PCBA, the desired lighting scheme is achieved.

[0084] Additional features include a programmed surface display (e.g., associated with OLED / TFT variants) depicting the currently selected gear in a magnified view at the center of the graphics display. The PCBA board may also include a main microcontroller with a serial communication protocol, not limited to LIN, SPI, and I2C. Other features include presenting a PCBA board with a main microcontroller using a serial communication protocol, and are not limited to any parallel interface established between the main microcontroller and the graphics display.

[0085] Figures 14 to 15 A pair of environmental views illustrating the ability to integrate the gear shifter assembly into various locations within the vehicle interior, such as... Figure 16 As further shown, the various positions are not limited to any of the steering wheel (shown as 82), steering column or other adjacent positions (shown as 84), instrument panel / dashboard or console (shown as 86). Figure 15Another variation of a potential mounting configuration for a roll-up shifter assembly associated with a vehicle center console is depicted, which is intended to represent the ability to modify the package size and position of the component 10 according to the mounting environment (i.e., to be integrated into the steering wheel or column rather than into the vehicle dashboard, IP, or console).

[0086] Figure 16 This is an illustration of an alternative mounting arrangement, providing a non-limiting variation of the scroll shifter assembly and presenting a redesigned rotating housing 88. The scroll shifter assembly, for example, is integrated into the central exposed position 90 of the vehicle steering wheel 92, and is easily accessible to the user's fingers when the user's hands (shown as 94 and 96) are resting on the steering wheel 92. As will be described, the redesigned scroll component again includes a display (in...) Figure 17 The wheel (shown as 98) and roller (also shown as 100) and all other internal components previously described in the corresponding component 10, while also allowing rotation / reorientation to occur simultaneously in response to rotation of the steering wheel 92, in order to always maintain the upright orientation of the component.

[0087] Figure 17 Is with Figure 16 A similar illustration, with the disc in a positive and initially upright orientation. Figure 18 yes Figure 17 The subsequent illustration shows the steering wheel rotating approximately 90 degrees counterclockwise, with the rolling shifter 88 also rotating in coordination within the steering wheel 92 to maintain a continuous upright orientation, regardless of the rotational position of the wheel.

[0088] Figure 19 illustrates a first alternative variant for coordinating the rotation of the rolling shifter assembly 88 with the operator's rotation of the steering wheel 92. This first alternative variant includes a toothed or other friction-engaged drive belt 102, interconnected with either a toothed or friction-engaged outer circumferential portion of the rolling shifter assembly 88 associated with the shape of rotation, or a central support gear or similar support 104 coupled to the steering wheel. This mechanical embodiment considers numerous sub-variations, including a centrally located gear or support 104 defining the central axis of rotation of the steering wheel 92, which can also rotate uniformly when rotated by the operator to continuously orient the circular cross-section shifter assembly 88 vertically. It is also conceivable that the steering wheel-supported assembly 88 is supported within a bearing ring or similar device (not shown) to allow free rotation in response to the action of the drive belt 102.

[0089] Continuing to Figure 20, a second alternative mechanical variant of Figure 19 is shown, in which a series of interconnected gears are provided to cooperatively rotate the reconstructed rotary shifter 88' in response to rotation of the steering wheel 92. The central gear or support is reconstructed as shown in 106, and the reconstructed central gear or support presents a toothed outer profile. An intermediate gear 108 is provided and directs rotation of the central axis-defined gear 106 to the toothed exterior of the reconstructed rotary shifter 88' to achieve a near-upright orientation of the assembly.

[0090] Figure 21 illustrates a third electric drive option, in which a sensor arrangement is employed to convert the rotation of the steering wheel 92 into a corresponding actuation and rotation of an electric motor 110, which operates as a power switching element. As shown, the motor's output shaft 112 incorporates a bevel gear portion 114, which in turn contacts the outer toothed profile of the shifter 88' and, when the motor is actuated by a separate sensor (not shown), converts the steering wheel's rotation angle into real-time rotation of the shifter 88' to maintain the shifter 88' in an upright orientation.

[0091] Continuing to Figure 22, another electronic redirection variant 116 of the scroll shifter assembly is shown, in which a similar sensor system (not shown) is used to measure the steering wheel angle for continuously redirecting assembly 116 to a position in an upright view. Non-limitingly, assembly 116 incorporates any type of capacitive or other touchscreen display, including PRND designators (areas 118, 120, 122, and 124). In this particular variant, the scroll wheel is replaced by upward arrows 126 and downward arrows 128 for shifting through gears using any type of capacitive touch or other touchscreen functionality.

[0092] Figure 23 provides an additional variation in which the electronically reorienting display 130 is paired with a similar rotation / reorientation and physical scrolling element 132 (similar to...). Figures 16 to 2 (As shown in either of 1) are provided separately. In response to any mechanical or electronic input, not limited to those described herein, and in order to keep both the rolling element 132 and the communication display 130 in an upright orientation, the individual elements rotate cooperatively (see arrows 134 and 136).

[0093] Figure 24 illustrates another variation of the rotation adjustment / reorientation display, see 138, where a central joystick or switch portion 140 is incorporated into the redesigned orientation display. As in the previous embodiment, rotation of the steering wheel 92 causes a sensor or other redirection, resulting in a responsive rotation of the display 138 (see double-headed arrow 142). Sub-variations of this configuration may include a central joystick or switch portion 140 fixed together with or rotatable together with a coaxially externally positioned display portion, the joystick's operation providing a transition between positions indicated on the display.

[0094] Figure 25 further illustrates a sub-variation including an automatic reorientation XY switch 144 (see further rotatably bidirectional actuation indicated by arrow 146). In this case, alternatively, a separate display (not shown) may be provided at another location on the vehicle (e.g., a fixed location) to provide a readout display of the selected shifter position.

[0095] Now continue to Figure 26 An exploded view of the rolling shifter assembly is shown (also in...). Figure 27 (Shown as 148 in the assembled perspective view). Component 148 generally corresponds to the previously shown... Figures 1 to 1 The components disclosed in 3 as 10, and according to another non-limiting embodiment of the invention, show a redesigned upper housing 150 and separate lower housing portions 152 and 154 for accommodating rollers 154 and TFT / OLED or segmented display 156, as well as PCBA 158, stop pawls 160 / 162 and support compression springs 164 / 166.

[0096] The upper housing 150 includes a pair of openings or cutouts defined by peripheral edge edges 168 and 170, which receive window-shaped bezels 172 and 174 for each of the rotary knob and the display, respectively. The assembly of the upper housing 150 with the engaging lower housings 152 / 154 includes an edge protrusion with openings in the upper housing (a pair of edge protrusions shown as 176), which engages and aligns with an upper protrusion (further shown as 178 and 180) associated with the assembled lower housings 152 / 154.

[0097] A lens with an outer peripheral skirt 182 is provided for sitting abutting against the lower portion of a cutout location 170 surrounding the upper housing 150. The lens includes a central upper embossed area 184 seated within the cutout and engaging with an associated frame 174. A lower housing split portion 152 includes an inner wall 186 defining a separate cavity for receiving a PCBA 158. A pair of annular ring supports for each of the lower split housing portions 152 / 154 are shown at 188 and 190, wherein the annular support 188 is constructed on the surface of the inner wall 186 opposite to the PCBA 158, and the annular support 190 is constructed on the opposite inner end wall of the other lower split housing 154.

[0098] A pair of ball bearing bushings 192 and 194 are provided, which are seated within the annular interior of the annular support 188 / 190 and support the opposing extended shaft portions 196 and 198 of the roller 154. An end magnet 200 is fixed (e.g., by end molding) to a receiving end position 202 of the shaft portion 196, such that, during assembly, the shaft portion 196 protrudes through a central axis defined in a defined aperture (see inner edge 204) in the inner wall 186, to position the end-rotatable magnet 200 close to a sensor mounted on the PCBA (see...). Figure 29 (204 in the middle).

[0099] Figure 27 Provided again Figure 26 A 3D assembly diagram of the rolling gear shifter assembly, and Figure 28 A sub-perspective view of a roller 154 with a spring-loaded stop pawl and a knob frame 172 is also provided. A side-arranged annular stop profile 206 is also described, constructed into the roller 154, with spring-loaded pawls 160 / 162 biased against this stop profile 206 to provide the desired operator tactile effect as the pawls move between the stop groove and the peak, resulting in a change in the spring's compressive force.

[0100] As mentioned earlier, the tactile force / effect can be affected by the height of the stop peak (see again). Figure 30 The influence of any of the following: 206), the depth of the interconnected stop grooves (see also 208), and the angle between each individual stop. Other tactile contributing features may include the surface shape of the stop profile, the roughness or material selection of the pawl and stop profile, or the spring stiffness. Again, as previously stated, the gear selection is based on the angular distance between each subsequent groove in the subsequent grooves.

[0101] Figure 29 It is along Figure 27The cross-sectional view taken by line 29-29 shows the internal assembly configuration of the rolling shifter assembly, in which the rolling knob 154 is overmolded onto the axial end support magnet 200 positioned relative to the sensor 204 mounted on the PCBA. Figure 30 Again, referencing from Figure 28 A partial enlarged perspective view of region 30, which better shows the tactile feedback interface established between the spring-loaded pawls 160 / 162 and the annular and undulating opposing side stop profiles (peaks 206 and grooves 208) of the rolling knob, the opposing side stop profiles being generally perpendicular to their outer knurled profiles.

[0102] Figure 31 yes Figure 27 The repeated diagram of the rolling gear shifter depicted in the image, and Figure 31 The bidirectional rotation of the roller 154 and the end support magnetic element 200 relative to the PCBA 158 and the sensor 204 is shown. Figure 32 Is with Figure 29 The repeated cross-sectional view shows the rotation of the end support magnetic element of the rotary knob relative to the sensor mounted on the opposite PCBA (see double-headed arrow 210), and at a specified angular position, causes the PCBA to send a signal to the motor control unit / module (not shown) indicating the need for a new gear.

[0103] Continue to Figure 33 Now shown is an application for steering wheel mounting according to another non-limiting embodiment (see also 212 in the assembly perspective view in general) (this is similar to the one previously shown in Figure 14 An exploded view of a rolling shifter assembly (referencing installation application 82). A redesigned lower housing 214 and upper housing 216 are provided, wherein the lower housing includes a pair of engaging bracket positions 218 / 220 for receiving and supporting the roller 222, such that the lower housing has an external annular gripping surface, thereby providing the desired grip profile when engaged by the user's fingers or thumb.

[0104] The lower housing 214 includes edge-extending ear-shaped locations 213, 215, and 217 for mounting to desired supports; for example, the lower housing 214 may also include a side location for the steering wheel. The upper housing 216 also includes a forward-facing, raised location 224 in which a slotted orifice (see interconnecting edge 226) is formed for receiving the knurled outer contour of the roller 222 and partially projecting the knurled outer contour of the roller 222.

[0105] The lower housing 214 also includes an open interior region 228 in which the PCBA 230 is supported. A pair of mounting screws 232 are provided for mounting the PCBA 230 via edge-defined apertures 234 / 236 aligned with mounting posts 238 / 240 with orifices defined in the lower housing 214. A display component 242 (also including but not limited to TFT, OLED, or any segmented variant) is supported within the upper housing 216 such that the illumination screen portion 244 of the display is visible through an additional window 246 in the upper housing. A connector strip 248 associated with the display (e.g., corresponding to a segmented display) extends from component 242 to connect to the PCBA 230 (see below). Figure 36 and Figure 39 (As best shown in the image).

[0106] A pair of wave springs 250 and 252 are provided, which are aligned with opposite sides of roller 222, and as will be further described, wave springs 250 and 252 include offset stop profiles abutting opposite sides of roller 222 (one of the stop profiles is in...) Figure 33 The central arched protrusions 254 and 256 (shown as 258) are shown. A circular magnetic element 260 is incorporated into a concave side position of the spindle or shaft support 262 of the roller 222. This may include, but is not limited to, molding the roller entirely around the magnetic element. A lens 264 is also shown, which may be seated against the interior of the upper housing 216 for covering the illumination portion 244 of the display component 242.

[0107] Figure 34 Provided again Figure 33 Front view of the gear shifter assembly. Figure 35 It is an enlarged, partially sectional 3D view depicting the installation... Figures 33 to 34 The shifter housing contains a roller 226 with a knurled outer profile, and also shows a side-support wave spring 250 / 252 offset against the opposite side of the roller (which is also provided by...). Figure 33 The hidden side stop profile 258' and the corresponding side positioning shaft support 262' of the roller 222 are depicted, the combination of which with the first opposing extension shaft 262 provides positional support for the wave springs 250 / 252. The wave springs 250 / 252 again replace the stop spring loading pawl of the previous embodiment, wherein the arcuate inner protrusion or bend (see again 254 / 256) and the annular stop profile arranged on the opposite side of the roller 222 (these also include) Figure 33 The first tactile stop contour 258 in the middle, and as Figure 35 and Figure 37The tactile stop profile 258' on the opposite side, which engages with the inwardly biased portion 256 of the second wave spring 252, provides a tactile interface.

[0108] Figure 36 yes Figure 34 A cross-sectional view of the shifter assembly is shown, generally illustrating the internal assembly configuration of the shifter assembly, wherein the rotary knob is overmolded onto a shaft end support magnet 260, which is positioned relative to a sensor mounted close to the PCBA, thereby forming part of an angled side support portion 268 of the PCBA 230 to be properly positioned relative to the rotational direction of the rotary knob magnet, where the sensor is located. Figure 35 and Figure 36 Each of the figures in the diagram is further depicted in 266. Figure 37 This is a sub-perspective view of roller 222, which has opposing support wave springs 250 / 252 for assisting in providing a tactile interface during roller rotation (again shown by opposing inward protrusions 254 / 256, which, together with the annular stop profiles 258 / 258' constructed on opposite sides in roller 222, define a corresponding first and second tactile interface).

[0109] Figure 38 yes Figure 34 The diagram repeats itself and depicts the bidirectional rotation of the roller as indicated by arrow 270. Figure 39 yes Figure 36 Another repeating figure, and Figure 39 The bidirectional rotation of the roller 222 and the end support magnet 260 relative to the PCBA 230 and the sensor 266 is shown.

[0110] Consistent with the previously described embodiments, the component is integrated into the desired position of the steering wheel (in this case, a lateral arrangement) allowing the driver to conveniently rotate or roll the roller 222 in either forward or backward bidirectional manner (again, referring to arrow 270) (e.g., while simultaneously keeping the associated hand on the roller). As the roller rotates, the magnetic element 260 rotates above the sensor 266, causing the processor component of the PCBA 230 to determine the required degree of angular motion to indicate a gear change to the vehicle ECU (engine control unit or module). The tactile effects and design options associated with the lateral bias wave springs 250 / 252 abutting against the opposing annular side stop profiles 268 / 268' of the roller 222 have also been described in previous embodiments and are reiterated herein in their entirety.

[0111] Continue to Figure 40An exploded view of the steering column of a rolling rotary shifter assembly (generally see 272) according to another embodiment of the invention is shown. The rolling assembly in the form of a mounted column includes each of an upper housing 274 and a lower housing 276, which are configured to assemble with each other, see the engaging protrusions 275 and 277 for the edge configuration of the lower housing in the receiving position (in... Figure 40 The middle part is hidden, but... Figure 44 (Depicted as 279 and 281 in the cross-sectional view), engaging protrusions 275 and 277 are constructed in opposite and aligned positions in the upper housing 274, and the assembly is mounted in such a manner that it is supported on and extends from the steering column (not shown).

[0112] The upper housing 274 also includes a forward-facing slotted aperture (see interconnect edge 278) for receiving and partially projecting the knurled outer contour of the associated roller 280. The upper housing 274 also includes a second forward-facing, laterally spaced slotted aperture (further defined by edge 282) for framing the illumination screen portion 284 of the display component 286 (again, including but not limited to, any of TFT, OLED, or segmented versions). As in the previous embodiments, edges 278 and 282 may also include the mounting of bezel window-like portions to provide an enhanced finish to the assembly.

[0113] The lower housing 276 also includes an open internal region 288 that receives the reconstructed components of the PCBA 290 (this is further aided by pairs of engagement protrusions 287 and 289 constructed within the lower housing for securing to the aligned side edges of the PCBA 290). A belt 292 and end connector 294 extend from the PCBA 290 to the base of the assembled rod, such that the belt is supported within the rod (see internal support rib shown as 296 associated with the lower housing 276), wherein external inputs (e.g., remote return parking sensors, etc.) are transmitted to the PCBA 290 via the belt 292. A separate belt 298 also extends from the display component 286 to the connection location on the PCBA 290.

[0114] A pair of wave springs 300 and 302 are provided, which are aligned with opposite sides of roller 280, and also include offset stop profiles against opposite sides (one of the stop profiles is in Figure 40The central arched protrusions 304 and 306 are shown in Figure 308. The circular magnetic element 310 is incorporated into the concave side of the spindle or shaft support 312 of the roller 280. This may again include, but is not limited to, molding the entire roller around the magnetic element.

[0115] A pair of corrugated brackets defining portions 314 and 316 are depicted projecting from the inner corrugated surface of the lower housing 276 for receiving opposing extended shaft portions (also shown as 312, and further referenced as 312' in Figures 42 and 43). The PCBA 290 also includes an angled shelf support 318 on which a sensor 320 (e.g., including but not limited to an inductive sensor) is positioned close to the magnetic element 310, such that rotation of the roller 280 in either direction causes the magnetic element to rotate relative to the sensor, thereby allowing the associated processor communicating with the PCBA to issue a shift instruction to the ECU when it determines that the magnetic element has rotated at a certain angle.

[0116] Figure 41 yes Figure 40 The assembly plan view of the embodiment is shown, and the scroll knob 280 and segmented or TFT / OLED display component 286 are depicted. Figure 42 is Figure 41 A cross-sectional view showing the upper housing removed, and depicting a PCBA 290, a strip 292 and a connector 294 supported on a lower housing 276, and a rotary knob 280 having an end support magnet 310 and side tactile support wave springs 300 and 302.

[0117] Figure 43 is a further enlarged view of Figure 42, with the upper housing removed, and depicts a PCBA 290 with a rolling knob 280, side-supporting wave springs 300 / 302, and a sensor 320 with proximal positioning. Figure 44 It is along Figure 41 The cross-sectional view is taken from line 44-44, and the rotatable support configuration of roller 280 is depicted from another advantageous position, wherein wave springs 300 / 302 and rotatable end support magnets 310 are positioned relative to PCBA 290 and sensor 320.

[0118] Figures 45 to 46 A pair of environment views are depicted (similar to those previously shown in...). Figures 14 to 15 (as presented in the text) and shows that it will be based on Figure 27 , Figure 34 and Figure 41 The ability of any of the shifter components to be integrated into various locations within the vehicle interior, not limited to the steering wheel (in... Figure 45(Shown as 212), steering column, rod, instrument panel / gauge panel (shown as 148). This may also include alternatively arranging components (again shown as 148) into the vehicle console, such as... Figure 46 As shown in the alternative environment view.

[0119] The present invention, according to any embodiment described herein, provides a roller-type vehicle shifter assembly that provides an operator interface for selecting transmission gears and provides tactile feedback to the operator when shifting gears, for example, again through an annular stop profile configuration on which a spring-loaded pawl is biased to travel through the peaks and grooves / valleys of the profile.

[0120] Additional features again include providing the operator with a multi-steady position (i.e., a fixed position for each gear). The scroll wheel design of the present invention also provides the operator with the ability to continuously scroll the wheel throughout the entire gear range, similar to the function of a computer mouse scroll wheel.

[0121] This gear shifter design further provides a return-to-parking function, which automatically resets the gear shifter position to the parking position in response to an external signal (such as a door opening) received by the processor mounted on the PCBA. Both the parking lock function and the neutral lock function are also included in this design to prevent the vehicle from shifting gears until certain prerequisites are met (such as the brake being applied), under which the PCBA electronically allows the rollers to shift gears.

[0122] The display provides gear indication based on any desired design configuration or orientation. Other features include housings and components that offer design flexibility for orienting the rollers in either an up / down or left / right orientation. Other considerations include providing design flexibility to reduce package size to accommodate numerous vehicle locations, particularly steering wheel or column and instrument panel (IP) or other locations.

[0123] Furthermore, it is conceivable that the roller assembly could be reconfigured for use in components other than vehicle gear shifting. Therefore, the term "gear shifter," in its broadest interpretation, is intended to be applied, by way of non-limiting examples, to windshield wiper control, volume control, or dimmer control functions.
