[0003] This invention generally relates to gear shifter assemblies. More specifically, it discloses a shiftable gear shifter adapted to be installed in different locations within a vehicle interior (steering wheel, lever, dashboard, IP, etc.) according to any desired orientation. A monostable and return-to-center switching switch is integrated into the assembly, which also provides direct drive and direct stop functionality by holding the shifter in the end stop position for a defined duration. The switching resistance is provided by any of the following: a spring and pawl mechanism, a torsion spring or a wave spring, or a keypad with a support plate, to provide additional advantages such as reduced parts count and elimination of wearing / friction parts. Background Technology

[0004] The prior art discloses various vehicle shifter designs. First examples in this regard are disclosed in each of US10,100,919, 10,190,675 and WO 2017 / 213869 (all belonging to Turney / Kongsberg); and a shifter assembly including a switching device (see breakdown) is taught. Figure 2 (at position 52), the switching device is incorporated into a cover hole located on the rod to be coupled to the cover 38 and used for movement between a first orientation and a second orientation via the cover. A sensor system is provided for interacting with an element mounted to the switching device to detect rotation of the cover between the first and second orientations.

[0005] SATA's US2014 / 0116179 teaches a gear transmission system incorporated in the form of a pair of paddle shifters into a vehicle steering wheel or column for enabling and disabling gear transmission events. The switch includes an enabled state and a disabled state, and is configured to selectively disable the operation of the paddle shifters.

[0006] Other shifter designs, such as those described in DeJonge 2004 / 0226801 (GHSP) or Muraki 2014 / 0007726, are accumulations of prior art and disclose other types of vehicle shifter components. Summary of the Invention

[0007] This invention discloses a shiftable gear selector assembly applicable to any of a gear shifter, windshield wiper controller, volume controller, or dimmer controller, and having a housing that supports a rotatable shift wheel including an edge protrusion accessible to the vehicle operator. The shiftable gear selector can 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.

[0008] In any embodiment, the component includes a housing incorporating a monostable switching switch or component. Several embodiments provide a stop profile constructed on the switching wheel, wherein a magnetic element is positioned close to a sensor mounted on a printed circuit board (PCBA) within the housing, such that the magnetic element displaces relative to the sensor in response to rotation of the switching wheel. A display component is mounted close to the PCBA.

[0009] At least one pawl is supported within the housing and biased against a stop profile, such that when the operator actuates the shift wheel, the pawl displaces relative to the profile to rotate the wheel until an accessible edge protrusion abuts the housing. A magnetic element rotates relative to a PCBA sensor to electronically indicate a shift via a processor associated with the PCBA. Alternative variations include a torsion spring, a wave spring, or any of a bias plunger and a key paddle to provide the necessary tactile effect when the shift wheel is actuated in either of the opposite monostable directions.

[0010] The housing also includes housings of various shapes for fitting into desired vehicle locations with attachable bottom covers. Any arrangement can be provided to support the toggle knob or wheel as a rotatable plate or bushing, as well as any arrangement of bias pawls or wave springs within the housing. Other features include a pair of windows defined in the upper portion of the main housing for housing either the toggle knob or wheel or the display components.

[0011] The display components also include any of thin-film transistors, organic light-emitting diodes, or segmented displays. A pair of windows are defined in the upper part of the main housing for housing each of the switching wheel and the display components.

[0012] The return-to-park function allows the PCBA to reset the shifter to park in response to a defined external input. Both a parking lock and a neutral lock function are provided to prevent gear shifting due to shift wheel rotation if the PCBA has not determined the necessary conditions for providing electronic shifting. Other features include direct shifting, where the PCBA-supported microprocessor directly shifts between park to drive, reverse to drive, drive to park, or manual to park positions when the shift lever is moved in either opposite direction and held for a predetermined period (e.g., more than 2 seconds in a non-limiting variant).

[0013] The housing can also be located in any other location within the steering wheel, steering column, dashboard, console, or instrument panel. In many variations, the magnetic element is attached to a toggle knob or wheel close to the sensor. Alternative variations include a bottom arrangement of the sensor switch integrated into a paddle-like element, and a keypad configuration for determining whether the toggle knob has been actuated, for the PCBA to indicate the desired gear.

[0014] In another variation, the 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 gear train or pulley system, or with the steering wheel support.

[0015] In the third electric drive option, a sensor arrangement is used 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 switching assembly to an upright position. Other variations include replacing the mechanical or electrical options with physically reorienting the combined display and shifter, and favoring the reorientation of the combined display portion of the shifter assembly, in this case including any type of capacitive or other touchscreen display positioned on the steering wheel.

[0103] Figure 75 It presents an additional ambient view of the gear shifter integrated into any center console or steering wheel lever. Detailed Implementation

[0104] Referring to the accompanying drawings, the present invention discloses several variations of a switching type vehicle gear shifter assembly, such as in... Figure 1 , 29 As shown in each of 39, 55, and 69, the shifter-type vehicle shifter assembly is adapted to be installed in different locations within the vehicle interior, including the console, dashboard, steering wheel, or steering wheel lever. As previously described, the shifter is adapted to be installed within the vehicle interior in any desired orientation. The assembly also provides the function of returning to park from any gear upon command, as well as electronic parking and neutral locking and direct shifting functions when the shift knob is pressed down for a predetermined time interval.

[0105] As will be further described in each of the following embodiments, the shifter assembly provides a variety of functions, including providing an operator interface for selecting transmission gears. Additional functions include: the ability to orient the assembly for up / down or left / right shifting 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.

[0106] First refer to Figure 1 An exploded view of a shifter assembly according to a non-limiting embodiment is shown, and the shifter assembly generally consists of... Figure 2The assembly is represented by component 10 indicated in the perspective view. As previously described, the shifter is suitable for installation in the vehicle interior according to any desired orientation and includes a monostable and return-to-center switching switch incorporated into the assembly. This switching switch also provides direct-to-drive and direct-to-parking functionality by holding the shifter in the end stop position for a defined extended period. As will be further described, the shifter resistance to the switch is provided by either a spring and pawl arrangement or by a torsion spring, wave spring, or other paddle / keyboard arrangement to provide additional advantages such as reduced part count and elimination of wearing / friction parts.

[0107] Refer again Figure 1 An exploded view of a shifter assembly according to a non-limiting embodiment is shown, and the assembly includes a main housing 12. The housing can be made of any suitable material, not limited to finished metals and / or rigid plastic composites. As shown, the housing 12 has a three-dimensional rectangular interior; however, it can also be reconstructed with any other encapsulation space defining an interior for supporting various components of the shifter assembly.

[0108] The bottom cover, shown as 14, is secured to the bottom edge 16 of the opening of the main housing 12 via a pair of mating screw receiving portions 18 located at the corners of the bottom cover. These screw receiving portions align with collars 20 arranged at the edges or corners around the bottom edge of the opening of the main housing 12, aligning the collars with the screw receiving portions when the main housing 12 is positioned on the bottom cover 14. Screws 22 are provided for securing the housing 12 and the bottom cover 14 together.

[0109] A pair of holes, such as those in a rectangular shape, are constructed within the top surface of the main housing 12 and are shown by interconnected edge edges 24 and 26, respectively exposing each of the external annular protruding contours of the switch 28 and the display component 30, which will be further described. The display component includes any PCBA and TFT / OLED / segmented display, and by way of a non-limiting example, the switch includes each of the PRNDS shifter position indicators corresponding to each of the parking, reverse, neutral, drive, and sport gear positions.

[0110] The window-shaped opening may include separate bezel displays, shown as 25 and 27, which are positioned above edges defining edges 24 and 26 constructed within the housing body 12. The main housing 12 also includes a notched side location 29 through which external wiring or cable connectors (e.g., potentially associated with a return-to-park function) can extend to an internally located PCBA (described below as 60). Other features include elongated positioning protrusions 31, 33, and 35 positioned within the bottom cover 14, which provide positioning and support for plates 46 and 48, as further described below.

[0111] The toggle switch 28 includes each of an extended handle or circular shaft 30 and an annular disc or wheel-shaped portion 32. For example... Figure 5 In addition, as best shown, the wheel-shaped portion of the switch also describes a protrusion or peak 34 for engagement by the user's thumb or finger, and opposing end stop shoulder configurations 36 and 38 associated with the outer diameter portion of the wheel-shaped portion (see also...). Figure 5 This limits the extent of the monostable rotation in either the first or second direction (see also...). Figures 7A to 7C The end stops 36 / 38 are also shown as ledges described on opposite sides of the wheel-shaped portion 32.

[0112] The bottom cover 14 also includes, as shown in 40, and additionally in Figures 7A to 7C Each of the pairs of support brackets shown, and the damping elements (described by annular or circular portions 42 respectively seated at angular receiving positions 41 on the upper part of the support brackets 40), provide a degree of cushioning and damping contact between the end stop configurations 36 / 38 on the switch wheel and on the opposing support brackets 40 abutting the bottom cover. The switch wheel portion 32 also includes a separate stop profile represented by a pair of arcuate and opposing extending ramps (see...). Figure 5 (As shown in the diagram, the switch is reconstructed at 44 and 44' on the side face of the switching element 28). As will be further described with reference to the associated pawl and stop spring components, a pair of opposing ramps 44 / 44' are used when the switch is rotated to... Figure 6A and Figure 6C It provides increased drag (tactile feedback) at either of the maximum rotation and monostable end stop positions shown.

[0113] Inside the main housing 12 are mounted a pair of first (or right) plates 46 and a second (or left) plate 48, and the pair of first (or right) plates 46 and second (or left) plates 48 include opposing annular recesses defining collars (see 50 and 52) for rotatably accommodating opposite ends of the toggle switch handle or shaft 30 (this also includes opposite extended end portions 30', as shown). Figure 5 (As shown in the diagram). At the support position of the shaft 30 / 30' on the opposite end of the switching wheel section 32 and positioned relative to the plate 46 / 48, there is a pair of ring-shaped support members shown as 54 and 56 to allow the switching wheel 32 to rotate about the shaft 30. Figure 1 The document also describes additional fastener screws 58, which secure the printed circuit board (or PCBA) 60 to rearwardly projecting support positions 62 and 64 of the selected left plate 48.

[0114] The pawl element 66 and the corresponding stop (or compression) spring 67 are supported in an additional seating position or pocket 69 of the right plate 46 in such a way that the pawl element is biased against the inclined portion of the stop profile 44 / 44' (see also) Figure 8 This provides a tactile interface for the operator. The tactile force / effect can vary depending on factors such as the height of the stop peak 44 / 44', the depth of the intermediate interconnecting groove of the stop peak, the angle between the stop peak and the groove, the surface shape / roughness / material selection of the stop pawl and the stop profile, or the relevant spring grade of the compression spring 67 or the tension spring 68.

[0115] In this way, and when the toggle switch 28 is rotated clockwise or counterclockwise, the opposite tilting stop profile 44 / 44' (see...) Figure 8 The pawl element 66 and the return compression spring 67 (which is also supported in the seat 69) are alternately biased to generate the necessary tactile resistance. Pairs of compression springs 68 may also be used alternatively or simultaneously to establish the desired tactile bias force applied to the switching element in response to rotation in either direction.

[0116] The present invention envisions a single or multiple pawls supporting a seated position against the inner side of the right plate 46. The degree of sensed resistance (also force) is further defined by: any height component of the ramp 44 / 44', the angle of the ramp relative to the flat end surface of the pawl wheel 32, the surface shape / roughness or material of the stop pawl and the pawl ramp, or the spring rate of the compression spring 67.

[0117] A pair of tension coil springs 68 are also described, which can be provided in an alternative arrangement without the use of the pawl 66, compression spring 67, and inclined ramp 44 / 44'. The alternative configuration of the tension coil springs 68 presents opposite coiled end positions, and the tension coil springs are connected to each of the lower posts 70 constructed on the inner surface of the right plate 46 and to the location connected to the switching wheel 28, as shown. Figure 4 Another optimal example is shown below. In this way, the rotation of the switching wheel 32 in either direction is counteracted by a given tension spring 68, causing the wheel to return to the central position.

[0118] The display component 30 can be mounted on top of the flat upper seat position 72 of the left plate 48 (see again) Figure 1 and Figure 4 The magnetic component 74 is mounted at the concave end position 75 of the shaft 30 of the switch, and as shown... Figure 10 As also shown in the best embodiment, the magnetic element 74 is adapted to rotate with the shaft near the sensor 76 located on the surface of the PCBA 60 (see [reference]). Figure 10 The sensor is connected to a processor component (not shown) of PCBA 60 to electronically indicate changes in gear position. In an alternative variant, the magnetic element 74 can be repositioned from the switch handle / shaft to another position within the assembly, and can be actuated by either a gear train and / or a pulley system (not shown) interconnected with the switch wheel portion 32 as the magnetic element 74 is displaced (rotated).

[0119] Figure 2 yes Figure 1 The diagram shows an assembled perspective view of the shifter assembly, depicting a wheel portion 32 of the shift switch protruding through a selected window 24 of the main housing 12, with the display 30 (TFT / OLED or segmented display) also protruding through a window 26 defined by a second annular edge. A pin-receiving connector 78 associated with the PCBA 60 is also described, accessible via a cutout location 29 in the housing, for receiving independent connector inputs (not shown), such as external wiring harnesses associated with the vehicle engine control unit and other external sensor inputs (e.g., associated with triggering a return to parking mode).

[0120] Figure 3 yes Figure 2 The rotating cross-sectional perspective view is shown, and the switch with an integral shaft 30, support bearings 54 / 56, and left mounting plate 48 component integrated with the outer housing and display components is described again. Figure 4This is another perspective view of the internal components of the shifter, in which the housing has been removed for clarity, including the orientation of the shift wheel portion 32, the internal clamping plates 46 / 48, and the display 30. The positions of the PCBA 60, the sensor 76, and the receiving connector 78 located on the opposite lower side of the PCBA 60 are shown again.

[0121] Figures 6A to 6C A series of front plan views of the component are described, in which the monostable switching switch 32 is depicted in the left-end stop position. Figure 6A ), center stop position (also as Figure 6B The non-actuated position in the middle and the stop position at the right end ( Figure 6C Any one of the positions in ). Figures 7A to 7C Corresponding to Figures 6A to 6C The document describes a series of 90-degree rotating views of the assembly, in which the housing is shown in a partially transparent manner to show the corresponding position of the switch: this corresponding position is positioned by means of the end stop 36 / 38 of the switch relative to the opposite support bracket 40 associated with the bottom cover, together with the damping element 42, to provide a degree of buffered contact between the end stop configurations on the switch wheel portion 32 when abutting against the opposite support bracket of the cover.

[0122] In this way, the driver can switch the gear selector up / down or left / right according to the desired orientation of the components within the vehicle. The stop profile, pawl / stop material, and spring rate together define the ability of the gear selector to return to the central (monostable) position after the driver releases it. The gear selector accordingly provides a bumpy shift in any direction corresponding to park to reverse, reverse to neutral, neutral to drive, and drive to motion (or the reverse sequence).

[0123] Figure 7D A partial view is provided illustrating the interface of a spring-compressible pawl 66 relative to a toggle switch ramp shown at 44, the toggle switch ramp being used for switching to... Figure 7A and Figure 7C Tactile resistance is applied at any position. The pawl 66 is also described in a stable single central position, which is centrally located between the outwardly extending ramps 44 / 44'.

[0124] Figure 8This is a partially transparent view of a toggle switch 28 with a wheel 32, and also depicts the arrangement of a stop pawl 66 and a return compression spring 67 for biasing the pawl against an inclined stop profile (also inclined portion 44 / 44') formed on the opposite end surface of the wheel 32. This again achieves monostable rotation of the switch in either the first or second direction, and the pawl 66 gradually causes a compressional shift along the inclined profile 44 against the spring 67 (see again). Figure 5 When this occurs, the compressive force applied by the switching wheel changes, thereby increasing the tactile resistance at the end stop contact point, such as... Figure 7A and Figure 7C As described in each of them, releasing the switch subsequently causes the inclined plane's abutment pawl 66 to apply the opposite bias, thereby causing the switching wheel to rotate back to its unbiased central position (see again). Figure 6B and Figure 7B ).

[0125] As the switch 28 is rotated, the magnetic element 74 rotates relative to the sensor 76 at a specified angular motion, causing the associated processor to indicate the gear change, which is then transmitted to the vehicle engine control unit (ECU).

[0126] Figure 9 yes Figure 2 The diagram is a basic repetition, and it shows bidirectional switching (see arrow 79), and Figure 10 Also provided Figure 3 The basic repetition of the illustrations depicts the bidirectional rotation of the switching wheel axle (arrow 81) with end-supported magnetic element 74 relative to the PCBA sensor 76, where each figure better illustrates the characteristics of the switching switch and wheel, as well as the end-supported magnetic element that, as it rotates near the PCBA-mounted sensor, sends a signal to the associated processor indicating gear shift conditions.

[0127] Figure 11A and Figure 11B A pair of views, shown as 80 and 82 respectively, illustrate the overall direct shift operation, in which... Figure 11A Indicator used to keep the toggle switch in place Figure 6C The movement of the position shown (e.g., any time period not limited to two seconds) to disengage from the parking gear (see...) Figure 11A (The prominent one) directly switches to drive mode (see) Figure 11B (The prominent one), and the ability to switch directly from either the parking or reverse gear to the drive gear, with the switch released to return to the drive position when in drive. Figure 11B The central position (also) Figure 6B(Not limited to, this can occur when the switch is held in the most distal abutting position on either side of the perimeter 24 of the window for a defined time period such as greater than two seconds.)

[0128] Figure 12A and Figure 12B The overall view showing another function of the direct shift operation is illustrated in a pair of views, 84 and 86, where Figure 12A The indicator will keep the toggle switch in place as well. Figure 6A The actions in the positions shown in the diagram are to switch from, for example, drive gear (such as...) Figure 12A (As shown) directly switch to the parking gear (see...) Figure 12B (The prominent one), and the ability to switch directly from Sport, Drive, or Neutral to Park. When in Park, the switch is released to return to the center position (also...). Figure 6B This can be repeated by holding the switch in the end-abutment position for a defined period of time (e.g., for more than two seconds according to a non-restrictive processor enable protocol, by which the relative rotation of the magnetic component via the PCBA sensor during this period will indicate a progressive shift within the gear range between the parking and drive positions).

[0129] Figure 13A and Figure 13B The diagram, shown as 88 and 90, illustrates the electronic return to the parking position, in which the shifter provides the ability to shift from any gear (e.g., according to the processor's commands) based on commands from the processor. Figure 13B Return to the parking position (see the prominent drive gear position). Figure 13A (in Chinese). Non-limitingly, the protocol is enabled by a remote sensor (not shown) that can communicate with the PCBA via its processor to indicate the occurrence of a return-to-parking event. By way of a non-limiting example, this could include a sensor that determines whether a vehicle door is open.

[0130] Figure 14A and Figure 14B Additionally, the electronic parking lock status associated with the gear shifter is shown, generally indicated by 92 and 94. Figure 14A ) or neutral lock state ( Figure 14B A pair of views. In the event of a parking lock event, the operator will need to press the brake pedal (not shown) to indicate to PCBA 60 that the shifter is released from the parking position. Otherwise, the shift switch 28 may be displaced within its rotational range, but the gear will remain in the parking position. In another case of a neutral lock, the shifter will remain in neutral according to the operator's command, wherein the shift switch 32 is again displaced within its rotational range, while the gear remains in neutral.

[0131] Figure 15 This is an illustration of a graphic display component shown at 96, which is associated with the shifter assembly and includes any TFT / OLED or segmented display variants, also at 30. Figure 16 Additionally, a related graphic display illustrating the variations is described, see 30', for example, which can be completed without etching or other custom processes. In each case, custom descriptions of multiple shifter positions PRNDM or PRNDS are provided, and any pixelated or segmented image can be provided on a non-etched surface (e.g., a thin-film transistor or organic LED display) via the shifter positions PRNDM or PRNDS.

[0132] 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 may again incorporate any of the variations of thin-film display (TFT), transistor LCD, or organic LED (OLED) display, and this improved display allows for the creation of any representation within the display surface geometry, not limited to color, pattern, or intensity (like, for example, not limited to, a circular display in a rotary shifter or a rectangular display associated with a linear door shifter). The invention also allows for the use of a clean display surface (without any paint or etching associated with known shifter position indicators PNRDS), and the invention is limited only by the operating software communicating with the associated circuit board and microcontroller.

[0133] In each variant, the display housing 98 (see again) Figure 15 Positioning as far away Figure 1 and Figure 4 The PCBA 60 shown can be combined with multiple LEDs or suitable lighting components (not shown). End connector 100 provides LED backlight power for segmented display variants. Connecting wires 102 / 104 are also shown, each extending from the surface display housing to connect to the PCBA. In one variant, the surface display is typically provided without any specific etching or painting representation, and this surface display can be modified in terms of color and intensity based on input received from the PCBA to achieve the desired lighting scheme.

[0134] The connector (strip shape) 106 provides LCD (liquid crystal) communication for segmented display variants and LED power for TFT and OLED display variants, and communicates the individual lines within the strip lighting element to selected segments on the display surface via this connector. In this way, and based on the collection of individual inputs from communication with the main microcontroller located on the PCBA, the desired lighting scheme is realized.

[0135] Additional features include a programmed surface display (e.g., associated with OLED / TFT variants) that describes the currently selected level (e.g., shown in a magnified manner in the center of the graphics display). Figure 15 The drive position is shown in magnified form in the center of the display. The PCBA board may also include a main microcontroller with a serial communication protocol, which is not limited to LIN, SPI, and I2C. Other features include presenting the PCBA board with the main microcontroller using a serial communication protocol, not limited to any parallel interface established between the main microcontroller and the graphics display.

[0136] Figures 17A to 17C A series of environmental views are described, demonstrating the ability to integrate the shifter assembly into multiple locations within the vehicle interior, as also shown by the steering wheel (in...). Figure 17A (shown as 108 in the middle), steering column (in) Figure 17B (shown as 110 in the middle), and the dashboard / instrument panel or console (in Figure 17C (shown as 112) any of them. Figure 18 Another variation of a potential mounting configuration for a shifter assembly associated with a vehicle center console is described (shown as 114). This variation aims to represent the ability to modify the size and position of the component's package depending on the mounting environment (i.e., to integrate it into the steering wheel or pillar rather than into the vehicle's dashboard, IP panel, or console). Without limitation, the PRNDS display can extend in either a horizontal or vertical manner at any mounting location, and is not limited to the steering wheel, pole, pillar, IP panel, or console.

[0137] Figure 19 This is an illustration of an alternative installation arrangement, in which a non-limiting variation of the shifter assembly is provided, and it can present a redesigned rotating housing (generally referred to as 116), which, for example, is integrated into the central exposed position 118 of the vehicle steering wheel 120, and is easily accessible to the user's fingers when the user's hands (shown as 122 and 124) are resting on the wheel 120. As will be described, the redesign of the shifter assembly again includes a display (in...) Figure 20 Both the steering wheel 120 (shown as 126) and the switching knob or disc (shown as 128) and all other internal components as previously described in the corresponding component 10, while also allowing rotation / reorientation to occur simultaneously in response to rotation of the steering wheel 120, so as to always keep the component in an upright orientation.

[0138] Figure 20 Is with Figure 19 A similar illustration, in which the disk is in a straight and initial upright orientation. Figure 21 yes Figure 20 The subsequent illustration shows the steering wheel rotating approximately 90 degrees counterclockwise, with the shifter assembly also rotating in coordination within the steering wheel 120 to maintain a continuous upright orientation, regardless of the steering wheel's rotational position.

[0139] Figure 22 A first alternative variant is shown for causing the shifter assembly 116 to rotate in coordination with the operator's rotation of the steering wheel 120. This first alternative variant includes a toothed or other friction-engaged drive belt 130, which interconnects with either a toothed or friction-engaged outer circumferential portion associated with the shifter assembly 11 and a central support gear or similar support 132 coupled in the steering wheel. This mechanical embodiment considers numerous sub-variations, including a centrally located gear or support 132 that defines the central axis of rotation of the steering wheel 120 and, when rotated by the operator, can uniformly rotate to impart a continuous upright orientation to the circular cross-section shifter assembly 116. It is also conceivable that the steering wheel-supported assembly is supported within a bearing ring or similar arrangement (not shown) to allow free rotation in response to the action of the drive belt 130.

[0140] Continue to Figure 23 , showed Figure 22 A second alternative mechanical variant is provided, in which a series of interconnected gears are provided to coordinately rotate the reconfigured shifter 116' in response to rotation of the steering wheel 120. The central gear or support is reconstructed, as shown in 134, and presents a toothed outer profile. An intermediate gear 136 is provided and redirects rotation of the central axis-defined gear 134 to the toothed exterior of the reconfigured shifter 116' to achieve a near-upright orientation of the assembly.

[0141] Figure 24 A third electric drive option is shown, in which a sensor arrangement is used to convert the rotation of the steering wheel 120 into a corresponding actuation and rotation of an electric motor 138, which operates as a power switching element. As shown, the motor's output shaft 140 engages with a bevel gear portion 142, which in turn contacts the outer toothed profile of the shifter 116', and this bevel gear portion converts the steering wheel's rotation angle into real-time rotation of the shifter when the motor is actuated by a separate sensor (not shown) to maintain the shifter's upright orientation.

[0142] Continue to Figure 25A further electronic redirection variant 144 of the shifter assembly is shown, in which a similar sensor system (not shown) measures the steering wheel angle to continuously redirect the assembly to an upright viewing position. Without limitation, assembly 144 incorporates any type of capacitive or other touchscreen display, including PRND indicators (areas 146, 148, 150, and 152). In this particular variant, the shifting element is replaced by an upward arrow 154 and a downward arrow 156 to shift through gears using any type of capacitive touch or other touchscreen functionality.

[0143] Figure 26 Additional variations are provided, in which the electronically reorienting display 158 is paired with a similar rotation / reorientation switching element 160 (similar to...). Figures 19 to 24 (As shown in either of the above) are provided separately. In response to any mechanical or electronic input, not limited to the mechanical or electronic inputs described herein, and in order to keep both the switching element 160 and the communication display 158 in an upright orientation, the individual elements rotate cooperatively (see arrows 162 and 164).

[0144] Figure 27 A further variation of the rotatable / reorientable display is shown, see 166, and a central joystick or switch portion 168 is incorporated into the redesigned orientation display in this variation. As in the previous embodiment, rotation of the steering wheel 120 causes a sensor or other reorientation, resulting in a responsive rotation of the display (see double-headed arrow 170). Sub-variations of this configuration may include a central joystick or switch that is fixed together with or rotatable together with a coaxial external positioning display portion, wherein manipulation of the joystick provides a transition between positions indicated on the display.

[0145] Figure 28 A further sub-variant is shown, including an automatic reorientation XY switch 172 (see further rotatably bidirectional actuation indicated by arrow 174). In this case, a separate display (not shown) may optionally be provided at another location on the vehicle (e.g., a fixed location) for providing a readout display of the selected shifter position.

[0146] Now continue to Figure 29 An exploded view of the shifter assembly is shown (see also usually...). Figure 30(Seen as 176 in the three-dimensional assembly diagram), and according to another non-limiting embodiment of the invention, the shifter assembly is used to integrate into any dashboard mount, instrument panel mount, or console mount application. The shifter shows an upper housing 177 and redesigned separate housing portions (right-hand 178 and left-hand 180) for defining the interior of the package and accommodating a shift wheel or knob 182, as well as a TFT / OLED / segmented display 184, a PCBA 186, a stop pawl 188, and a support compression spring 190.

[0147] The upper housing 177 includes a pair of holes or cutouts defined by peripheral edge edges 192 and 194, which receive window-shaped bezels 196 and 198 for each of the switch knob 182 and display 184, respectively. The assembly of the upper housing 177 with the engaging lower housings 178 / 180 includes perforated edge protrusions (a pair of protrusions shown as 200) in the upper housing that engage aligned upper side protrusions (also shown as 202 and 204) associated with the assembled lower housings 178 / 180. Additional mounting screws 201 are provided for securing the separate lower housing portions together via alignment with a pair of holes 203 and 205 formed in the housing portions 178 and 180.

[0148] Lens 206 is seated against the lower side of the edge defining the cutout location 194 around the upper housing 177. Optionally, the lens includes a central upper embossed area seated within the cutout and engaging with an associated frame. The lower housing separation portions 178 / 180 may include any arrangement of internal walls or supports for positioning and securing the PCBA 186 relative to the switching element 182 (see wall 207 and...). Figure 31 (Supporting members shown in cross-sectional views 208 and 210). Although not clearly shown, one or more annular ring-shaped supporting members (see also: [see also]). Figure 31 (As shown in 212 and 214) can be located within each of the lower split housing portions 178 / 180, wherein the annular support 212 is constructed on the surface of the inner wall 207 opposite to the PCBA 186, and the annular support 214 is constructed on the opposite inner end wall of the other lower split housing 180.

[0149] A pair of ball bearing bushings 216 and 218 are provided, which are seated within the annular interior of the annular support members 212 / 214 and support the opposing extended shaft portions 220 and 222 of the switching knob 182. An end magnet 224 is secured (e.g., by end molding) to a receiving end position 226 of the shaft portion 220, such that during assembly, the magnet is located near the PCBA-mounted sensor (see [link to PCBA mounting]). Figure 31 (As shown in 228). As also shown, PCBA 186 includes a separate wire harness receiving connector 187, which is exposed during installation through a cutout 189 in the right-side split housing 178.

[0150] like Figure 29 As further shown, a curved or clamping shape of the overmolded portion is described at 230, and this overmolded portion may be initially formed together with the left-side separate housing 180, or may be formed in a second injection overmolding step into the opening-facing cavity of the left-side housing 180 (see also...). Figures 33A to 33C (As shown in each of them). The switching knob 182 is configured to resemble Figure 1 The corresponding construction described in the text is 28, and as... Figure 37 As further shown, it includes an annular outer contour, which includes a finger or thumb tip 232, and corresponding and proximal knurled or roughened features 234 and 234', which are close to either side of the tip 232 and facilitate gripping during knob switching actuation.

[0151] like Figure 37 As further shown in the perspective view of the switching knob, the side profile (e.g., arranged perpendicular to the outer annular profile) can be further shown by first and second interconnected and side-mounted bevels, see 236 and 238, which show a generally “V”-shaped profile against which the spring-loaded pawl 188 is biased. The switching knob also presents an arcuate recess constructed in the annular sidewall of the switching knob (see Figures 33A to 33C (further represented by concave end walls 240 and 242), such that the switching knob 182 is positioned within the left housing 180 such that its interior, positioned above the molded portion 230, sits within the arcuate groove, to restrict either bidirectional rotation, and until the opposing end walls 240 / 242 contact the encasing molded portion 230 (this further corresponds to the opposing inclined ramps 236 / 238 during either or both bidirectional restricted rotation of the switching knob in monostable state). Figure 37 ) Contact spring-loaded pawl 188 (see again) Figure 32A / Figure 33A and Figure 32C / Figure 33C ) and return to the central ( Figure 32B / Figure 33B (in the way)

[0152] Figure 30 yes Figure 29 A three-dimensional assembly diagram of the shifter assembly, wherein the shift knob is shown in the central (unacted) position. Figure 31 It is along Figure 30The cross-sectional view taken by line 31-31 shows the internal assembly configuration of the shifter assembly, in which the shifting element or knob is overmolded onto a magnetic element 224 supported at the shaft end, which is positioned relative to the PCBA-mounted sensor 228.

[0153] Figure 32A yes Figure 30 A plan view of the shifter assembly is shown, in which the shifting element is depicted in a monostable left position and a bumpy end stop position (see the overmolded portion 230 indicated by the contact first end stop 240). Figure 32B yes Figure 32A The following is a plan view illustration of the shifter assembly, in which the shifting element is depicted as returning to the central stable position. Figure 32C yes Figure 32A Further subsequent plan view illustrations of the shifter assembly, wherein the shifting element is depicted in a monostable right-hand position and a bumpy end stop position (the overmolded portion 230 contacts the second end stop 242).

[0154] Figure 33A It is along Figure 32A The cross-sectional view taken from line 33A-33A shows the switching knob in the left monostable position, corresponding to the contraction of the internal spring bias pawl 188 when it is displaced on the inclined portion (236) provided along the first side of the knob. Figure 33B It is along Figure 32B The cross-sectional view taken from line 33B-33B shows the switching knob in the central stable position, where... Figure 33C Provided along Figure 32C A further cross-sectional view taken from line 33C-33C shows the toggle knob in the right monostable end position, corresponding to the contraction of the internal spring-biased pawl 188 as it moves along the second interconnected and side-mounted ramp portion (238) of the knob. The engagement between the overlying molded portion 230 and the opposite end stops 240 / 242 provides damping to reduce noise when the toggle switch is in its full travel (with...). Figure 33A and Figure 33C The end stop (contacting the end stop in the middle) and the damper that engages with the feature are on the switching knob to prevent the device from exceeding its travel.

[0155] Figure 34 yes Figure 30 The basic repeat of the switching shifter is shown, and the bidirectional monostable end rotation aspect of the switching knob and end support magnetic element relative to the PCBA and the mounted sensor is illustrated (see bidirectional arrow 244). Figure 35 yes Figure 31The cross-sectional view is essentially repeated and shows the rotation of the switching knob and the magnetic element of the end support relative to the opposing PCBA-mounted sensor (see double arrow 246), which causes the PCBA to send a signal for the desired new gear to the engine control unit / module.

[0156] In this way, the operator can switch up / down or left / right according to the desired orientation of the device in the vehicle. The stop profile, pawl / stop material, and spring rate define the ability of the switch to return to the central position after the driver releases the switch. A single impact movement of the switch provides incremental shifting of the gear position between each of the PRNDS positions (P=>R, R=>N, N=>D, D=>S, or vice versa).

[0157] Figure 36 This is a perspective view of the subassemblies of the switching knob 182, PCBA 186, and spring-loaded stop pawl 188 viewed from different orientations, with the housing portion removed. Figure 38 yes Figure 36 The rotating side plan view, and better shows the stop profile offset contact between the pawl 188 and the compression spring 190 and the side ramps (also 236 and 238) constructed in the switching knob 182.

[0158] As previously described, when the driver presses the toggle switch using their finger, thumb, or any other means, the toggle element rotates together with the stop profile (slope 236 / 238). The slope profile 236 / 238 engages with the stop pawl 188 supported by the compression spring 190. As the pawl 188 moves along / upwards the monostable pawl (either of slopes 236 / 238), the spring is compressed and the operator feels the associated force. This force is again defined by any of the following: the height of the stop peak, the depth of the pawl groove, the angle between the peak and the groove, the surface shape and roughness of the materials of the stop pawl and the slope profile, and the spring rate.

[0159] Gear selection is also based on a specific rotational distance of the shift knob and end support magnetic element 224 relative to the PCBA-mounted sensor 228. At this time, the associated processor for the PCBA instructs the gear change to be communicated to the vehicle ECU unit. The parking lock and neutral lock functions also operate in a similar manner to those described in the initial embodiment. The direct-to-park or drive shift function is also operated by the operator holding the shift knob downwards in the selected monostable end-stop position for a selected time interval (e.g., >2.0 seconds), thereby shifting the gear selection from park to drive and vice versa.

[0160] Continue to Figure 39This is an exploded view of a shifter assembly according to another non-limiting embodiment for use in a steering wheel mounting application, and Figure 39 Variations of wave springs and torsion springs are shown to provide the desired tactile feedback and monostable single-bump shifting function. A redesigned lower housing 250 and upper housing 252 are provided, wherein the lower housing includes a pair of integral bracket positions 254 / 256, and an inner molded portion 255 is constructed between the pair of integral bracket positions, defining a monostable end stop position for rotating the shift wheel, also shown as 248. The redesigned shift wheel 248 again includes an outer annular gripping surface (knurled portions 258 / 258' and inserted peaks 260) to provide the desired gripping profile when engaged by the user's fingers or thumb.

[0161] The lower housing 250 also includes edge-extending ear-shaped locations 258, 260, and 262 for mounting to desired supports; for example, the lower housing 250 may also include side locations for the steering wheel. The upper housing 252 also includes a forward-facing, raised location 264 in which a slotted hole (see interconnecting edge 266) is formed to receive the knurled outer contour of the switching wheel 248 and to partially protrude the knurled outer contour of the switching wheel 248.

[0162] The lower housing 250 also includes an open interior area (typically at 268) for supporting the PCBA 270. A pair of mounting screws 272 are provided for mounting the PCBA 270 via holes 274 / 276 defined on an edge aligned with perforated mounting posts 278 / 280 defined in the lower housing 250. A display component 282 (again including but not limited to TFT, OLED, or any segmented variant) is supported within the upper housing 252, and the illumination screen portion 284 of the display is made visible through an additional window 286 in the upper housing. A connecting strip 288 associated with the display (e.g., corresponding to a segmented display) extends from component 282 to connect to the PCBA 270 (see reception location 289, also as...). Figure 41 (as shown in the image).

[0163] A pair of wave springs 290 and 292 are provided, which are aligned with opposite sides of the switching knob or wheel 248, and as will be further described, the wave springs include centrally arcuate protrusions 294 and 296 biased against opposite side stop profiles of the switching wheel 248 (see also...). Figure 46 and Figure 48 (As shown in the diagram, the ramps are 298 / 300 and 302 / 304 in each pair). The ramps define opposing peaks, with the grooves defined by the innermost recessed locations 306 and 308 established between each pair of ramps 298 / 300 and 302 / 304 (see also...). Figure 46).

[0164] A circular magnetic element 310 is incorporated into the concave side of the main shaft or shaft support 312 of the switching wheel 248. This may include, but is not limited to, molding the switching wheel integrally around the magnetic element. A lens 314 is also shown, which may be seated against the inside of the upper housing 252 for covering the illumination portion 284 of the display component 282.

[0165] Figure 40 yes Figure 39 A front view of the shifter assembly, wherein the shift wheel and display are assembled within the clamping upper and lower housing portions. Figure 41 yes Figure 40 The cross-sectional perspective view shows the internal assembly configuration of the shifter assembly, in which the shifting element or knob 248 is overmolded onto the shaft end support magnetic element 310, which is positioned relative to a PCBA-mounted sensor, which is shown separately at 316, and the PCBA-mounted sensor may include, but is not limited to, any inductive or Hall effect sensor.

[0166] Given the orientation of the PCBA 270 relative to the magnetic element 310 mounted at the shaft end, the sensor 316 can be mounted on the vertical extension shelf 318 of the PCBA, thereby properly positioning the sensor to the magnetic element in a closely spaced and relative manner. As previously described, and when the driver presses the toggle switch with their finger, thumb, or other means, the toggle switch rotates, causing the magnetic element 310 to rotate above the sensor 316, wherein the gear position is changed and communication (e.g., via the PCBA operating processor) is established to the vehicle engine control unit (ECU).

[0167] Figure 42A yes Figure 39 A plan view of a waveform spring variation of a shifter assembly is shown, wherein the shifting element (represented by a shifting knob with a peak position 260) is described in a monostable upper position and a bumpy end stop position. Figure 42B yes Figure 42A The following plan view illustration shows the shifter assembly, where the shifting element is depicted returning to a central stable position, and Figure 42C yes Figure 42A Further subsequent plan view illustrations of the shifter assembly, in which the oscillating element is depicted in a monostable lower position and a bumpy end stop position.

[0168] Figure 43A It is along Figure 42A The cross-sectional view taken from line 43A-43A shows the switching knob in the upper monostable end position, corresponding to the contraction of the inclined portion of the wave springs 290 / 292 along the first side of the knob (see again). Figure 48 (298 / 302 in the middle). Figure 43A The inner molded portion 255 of the lower housing 250 is also shown, which is seated in an annular recessed channel or track shown as 320, and has opposing end stops 322 and 324 defined in a switch knob 248.

[0169] Figure 43B It is along Figure 42B The cross-sectional view taken from line 43B-43B shows the switching knob in its central stable position, where... Figure 43C Provided along Figure 42C The cross-sectional view taken from line 43C-43C shows the switching knob in the lower monostable end position, corresponding to the wave springs 290 and 292 along the second interconnection and the beveled portion provided on the side of the switching knob 248 (in addition to...). Figure 48 The contraction is shown in 300 / 304.

[0170] In this way, the driver can switch up / down or left / right according to the desired orientation of the device in the vehicle. The stop profile, wave spring / stop material, and wave spring stiffness define the ability of the switch to return to the center after the operator releases it. The assembly also provides a bumpy monostable gear shift in any direction via incremental positions (again, P=>R, R=>N, N=>D, D=>S, and vice versa). Simultaneously, the inner bends 294 / 296 of the wave springs alternately travel along either of the oppositely oriented pawl ramps 298 / 302 and 300 / 304 of the wave springs 292 / 290, wherein the monostable central position is defined by the central grooves 306 / 308 of the opposing wave springs of each.

[0171] Figure 44 yes Figure 40 The basic repeat of the switching shifter is shown, and the bidirectional monostable end rotation aspect of the switching knob (see bidirectional arrow 326) and the end support magnetic element relative to the PCBA-mounted sensor is illustrated. Figure 45 yes Figure 41 The cross-sectional view is essentially repeated and shows the rotation of the switching knob and end support magnetic element (double-headed arrow 328) relative to the opposing PCBA-mounted sensor, which causes the PCBA to send the required new gear signal to the engine control unit / module.

[0172] Figures 49A to 49C Usually corresponds to Figures 42A to 43C And it describes the stop position at the upper end of the monostable state ( Figure 49A Arrow 336 in / 50A), returns to the central position and the lower stop position ( Figure 49CThe corresponding operation of each of the alternative toggle knob variations in / 50C (reverse arrow 338) is provided. The molded portion 255, positioned between the toggle wheel support brackets 254 / 256, provides the necessary damping effect to reduce noise when the toggle switch is actuated at its full stroke (at the upper and lower stops). The damper also engages with the function of the toggle switch to prevent the device from exceeding its stroke. The alternative variation incorporates a torsion spring 330 (see again) in a substation of a pair of wave springs 290 / 292. Figure 39 The torsion spring has opposing extended end legs 332 and 334. The torsion spring 330 sits on an externally reconstructed member of the switching axle described as 312' (and as...). Figure 52 (Extended relative to the inner shaft portion 312 as shown).

[0173] Figure 50A It is along Figure 49A The cross-sectional view taken from line 50A-50A shows the toggle knob in the upper monostable end position, corresponding to the contraction of the torsion spring 330 when it shifts along the inclined portion provided on the first side of the knob (e.g., also for...). Figure 48 (298 / 302, relative to the inclined plane of the pawl). Figure 50B It is along Figure 49B The cross-sectional view taken from line 50B-50B shows the switching knob in the central stable position (corresponding to the seat position). Figure 46 The inner curved portion 294 / 296 of the wave spring 290 / 292 within the central groove 306 / 308 shown. Figure 50C It is along Figure 49C The cross-sectional view taken from line 50C-50C shows the switching knob in the lower monostable end position, corresponding to the contraction of the torsion spring 330 in its inclined portion (300 / 304 of the knob) along the second interconnect and on its side.

[0174] Figure 51 This is a partial side view of the toggle knob, showing a torsion spring 330 with side support. The torsion spring twists (via offset legs 332 / 334 at opposite ends) in response to rotation of the knob 248 to increase the rate of torsion in response to an inductive load, and the rate of torsion increases with increasing resistance of the knob. The torsion spring force is further defined by one or more parameters, including material, wire geometry, number of coils, and spring diameter. The torsion spring can also be configured with a desired preload, such as in the assembled / central position. Figure 49B / Figure 50B ).

[0175] Figure 52A side sectional perspective view of a switching knob with a torsion spring 330 supported by lateral supports is presented, and the opposing extended legs (shown at 332 on the outside of the extended legs in contact with a fixed abutment position 336 inside the housing) are described again. In response to rotation of the switching knob from the center in either direction, the extended legs generate a resistance load on the switching wheel when the switching knob abuts against a selected inner leg 334 or outer leg 336 of the torsion spring. A biasing force is applied to the switching knob in response to rotation in either direction, causing either of the spaced and opposing arcuate edges 331 and 333 constructed along the opposing cut positions of the switching knob axis portion 312' to bias against a selected extended and fixed abutment support leg 332 or 334 of the torsion spring.

[0176] Figure 53 It is similar to Figure 52 The view, in a non-sectional manner, depicts the switching knob 248 supported on the bracket portions 254 / 256 of the lower housing 250, and describes the mounting arrangement of the torsion spring 330 within the reconstructed switching knob shaft portion 312', which again reveals the interior of the annular bore and the lower cutout profile that reveals the spaced and opposing abutment edges 331 / 333. Figure 54 This is another partial perspective view showing a torsion spring 330 without a switching knob, and depicting the inwardly curled leg 334 of the spring 330 contacting a separately positioned retaining abutment shown as 338, with the torsion spring 330 positioned relative to the inner side of the bracket portion 254 relative to the externally positioned abutment 336. In this way, rotation of the switching knob in either direction is relative to and counter-biased by either of the extended legs 334 or 336 contacting the opposite edges 331 / 333 of the knob, and in a manner that affects the return of the switching knob to the central position, as... Figure 51 As shown in the image.

[0177] Continue to Figure 55 An exploded view of a shifter assembly according to another non-limiting embodiment for use in a steering wheel mounting application (see also...) Figure 56 (Assembled perspective view 340). Similar to the previous embodiments, an upper housing 342 and a lower housing 344 are provided, clamped together to define a package receiving space.

[0178] The lower housing 344 also includes edge-extending ear-shaped locations 346, 348, and 350 for mounting to desired supports; for example, the lower housing 344 may additionally include a side location for the steering wheel. The upper housing 342 also includes a forward-facing, raised location 352 with a slotted opening (see interconnected edge 354) formed therein for receiving a further reconfigured outer portion 356 of the shift wheel or knob 358 and allowing the further reconfigured outer portion 356 of the shift wheel or knob 358 to protrude.

[0179] The lower housing 344 also includes an open internal region (typically at 360) in which the PCBA 362 is supported. An additional mounting screw (as shown at 364) is provided for mounting the PCBA 362 via a hole 366 defined on the edge edge aligned with a perforated mounting post 368 defined in the lower housing 344. Further internal support features (see 369) are constructed within the upper housing 344 to receive and position the upper edge of the PCBA 362.

[0180] The display component 370 (again including but not limited to any TFT, OLED, or segmented variant) is supported within the upper housing 342, and the illumination screen portion 372 of the display is made visible through an additional window 374 in the upper housing. A connector strip 376 associated with the display (e.g., corresponding to a segmented display) extends from the component 370 to connect to the PCBA 362 (see edge proximity cutout profile 378 in the lower housing 344, which aligns with the underside-positioned receiving connector (not shown)) for connection to the wiring harness 376.

[0181] A keyboard 380 is provided that typically mates with the contours of PCBA 362, such that the keyboard is positioned on top of the PCBA when mounted within the lower housing 344. A plurality of keyboard buttons, including external sub-pairs 382 / 384 and internal sub-pairs 386 / 388, are incorporated into the keyboard 380 and aligned with contact points (external subsets 390 / 392 and internal subsets 394 / 396) in PCBA 362. As will be further described, the keyboard arrangement replaces any spring-loaded pawls, wave springs, or torsion springs used in previous embodiments to provide the desired resistance (tactile effect) during shifting of the knob 358.

[0182] The inner knob housing 398 has a generally rectangular (pseudo-shoebox) shape and a concave interior for accommodating a relatively rectangular end face profile 399 that defines the semi-knob shape of the switch knob 358. A central internal support post 400 is shown associated with the inner knob housing 398, which is positioned to allow for bidirectional switching movement of the knob to a limited degree and is located on the lower side of the switch knob 358 (see [link]). Figure 59 (Shown as 401 in the cross-sectional view).

[0183] The paddle-shaped portion 402 is fixed to the central position of the switching knob 358 in terms of rotation. The paddle-shaped portion includes opposite end positions 404 and 406 aligned with the external keyboard buttons 382 / 384 (see also...). Figure 58 The internal sensors / switches 386 / 388 on the PCBA alternately contact the underside of the internal knob housing 398 (see...). Figure 59 The toggle knob 358 is designed to limit the restricted pivoting range of the toggle knob and the inner knob housing relative to the PCBA when the paddle-shaped member 402, which is supported by the sides, is activated. The toggle knob 358 also includes another side extension 408 on the side opposite to the paddle-shaped member 402, which overlaps with the support edge of the inner knob housing 398. A cutout in the side of the inner knob housing defines the central axis 410, and the cutout positions the central axis support of the paddle-shaped member 402 and the opposite side extension 408 in a manner that prevents rotation of the knob, for example, when the operator presses a button to depress the internal sensor switch 388 / 386, and also prevents the keypad button 384 or 382 from being pressed when the toggle is rotated up or down (in which case the sidewall of the inner support feature 369 provides corresponding restriction, depending on either the press / not rotate or rotate / not press condition being established).

[0184] Additional features include a knob-covering mold 412 that generally mates with the switching knob 358 in configuration. (See reference...) Figure 64 As further described, the central protrusion 414 of the knob cover mold 412 can be pressed down during installation to displace the inner knob housing 398, for example, in a non-limiting configuration, to contact the inner knob housing with the inner keypad buttons 394 / 396 and the aligned sensor switches 394 / 396, in order to initiate a return to the parking state via the PCBA 380.

[0185] Figure 56 yes Figure 55 The front plan view of the shifter assembly, and Figure 57 Provided with Figure 56A similar illustration shows the upper housing removed to better depict the inner knob housing 344, and the paddle 402 having opposite contact ends 404 / 406 and keyboard buttons 382 / 384 to provide the necessary shifting resistance during monostable switching of the knob 358 in either direction. Figure 58 It is a cross-sectional perspective view of a switching knob having a covering mold 412, a paddle-shaped component 402, a keyboard 380 and keyboard buttons (outer) 382 / 384 and (inner) 386 / 388, the switching knob being used to provide monostable switching in either a first or second direction.

[0186] During operation, and as the toggle knob or switch is rotated, from the knob axis 410 (see again) Figure 55 The end positions 404 / 406 of the extended paddle 402 are also caused to pivot. Upward switching causes the upper paddle end 406 to move downward to contact the opposite keypad 384. When the keypad 384 contacts the lower switch 392 on the PCBA 362, the circuit closes to confirm the upward switching selection (e.g., corresponding to a gear change).

[0187] Conversely, a downward switch causes the corresponding lower paddle end 404 to move downwards and contact the opposing keypad 382, ​​which closes the circuit when it contacts the corresponding switch 390 on the PCBA, thus confirming that a downward switch selection has been made. As previously described, the knob can be switched as described above or by pushing the knob inwards (see again). Figure 64 (As indicated by directional arrow 416 in the diagram) to engage the parking position, which causes one or more keypad buttons (see again 386 / 388) located below the internal knob housing 398 to engage with the PCBA sensor / switch assembly 394 / 396 located below.

[0188] Figure 59 It is along Figure 58 Further rotational and cross-sectional views taken from line 59-59 show sensor switches 394 / 396 positioned on the underside of the PCBA362, which alternately engage with the underside of the internal knob housing 398 during rotation in either the first or second switching direction. Figure 60 This is another partial side perspective view of the internal switching knob housing 398, the knob covering mold 412, and the lower housing 344, which is to illustrate the switching movement of the components from different advantageous positions.

[0189] Figure 61 It is similar to Figure 56 The illustration shows the bidirectional movement of the switching knob, as further described by arrow 418. Figure 62 yes Figure 58The basic repeating view is shown, and the direction of rotation of the elongated paddle 402 in contact with the resistance sensing keyboard buttons 382 / 384 is described (see rotation arrow 420).

[0190] Continue to Figure 63 It presented Figure 55 Further rotation and 3D cross-sectional views of the switching components, and Figure 63 The description includes a toggle element supported as a rotatable paddle 402, external keyboard buttons 382 / 384, a PCBA 362, and sensor switches 390 / 392. Figure 64 Is with Figure 60 A similar illustration depicts pushing inward to the parking position (pressing button 416 down again), where pressing the toggle knob causes the keyboard buttons 386 / 388 located below the inner knob housing to descend and contact the sensor switch (394 / 396) located on the bottom side.

[0191] Continue to Figure 65 It provides a graphical description of various force travel curves corresponding to different keypad configurations to change shifter resistance in response to knob switching. This includes a first configuration of keypad configuration 422 corresponding to a first force travel curve 424, which is generated by the force graph curve established by the contact of corresponding ends 404 / 406 of the paddle 402 during pivoting of the shift knob 358 and the inner housing 398.

[0192] The keyboard structures of the additional pairs and their corresponding force stroke diagrams are shown in figures 426 / 428, 430 / 432, 434 / 436, 438 / 440, and 442 / 444. These descriptions all represent the difference in shifting force resistance in response to downward pivoting of the paddle-shaped end actuated to bias contact, and are intended to replace the effects of spring-loaded pawls, wave springs, or torsion springs in previous embodiments.

[0193] Figure 66 This is a further graphical description, illustrating the effect of different force distributions on keyboard button resistance with respect to keystrokes. Figure 65 The force-stroke curve profiles presented in the figures are consistent. Figure 66 The graphical description provides an X-axis 446 representing the travel distance (in millimeters) and a Y-axis 448 representing the applied force (grams).

[0194] The peak travel S1 (shown at 450) and contact travel S2 (shown at 452) are represented along the X-axis 446. The force distribution indicator also includes each of the following: peak force (FP) shown at 454, maximum restoring force (FU) shown at 454, contact force (FC) shown at 458, minimum restoring force (FR) shown at 460, drop force FD (FD = FP – FC) shown at 462, and associated drop force FG (FG = FP – FM) shown at 464. Position variables include each of the following: origin (O) 466, peak point (P) 468, return point (R) 470, contact point (C) 472, and maximum return point (M) 474. In each case, the shifting force and the corresponding key resistance are defined by the button geometry and the selected button material (not limited to different grades of polymer or rubber compositions, including composite materials, etc.). The additional peak stroke force is shown separately as 476 and defines the maximum value of the stroke and force and force components.

[0195] Figure 67 This is a plan view of a shifter based on another variant 478, and describes the shifting modes constructed into a redesigned upper housing in reverse order. This representation is intended to correspond to any of the previously described shifter assemblies herein, and wherein a display is incorporated into the upper housing such that the individual shifter positions are represented in reverse order by parking position 480, sport drive (S / D) position 482, neutral position 484, and reverse position 486.

[0196] The protruding position of the switching knob is shown as 488, located within a concave, forward-facing portion 490 of the upper housing, wherein the peak gripping portion 492 is easily accessible to the operator in either an up or down switching manner. An operation button description 494 may also be provided in conjunction with the parking position identifier 480. Without limitation, the functional lighting scheme may include a first color (e.g., but not limited to, red) associated with the parking position 480, and a second color (not limited to white) corresponding to each of the other S / D 482, N 484, and R 486 positions.

[0197] As in the aforementioned embodiments, each of the parking lock, neutral lock, and direct shift (e.g., parking to reverse and reverse to parking) functions can be integrated into the redesigned shifter 478. The shifter button 488 can be positioned in the upward direction (see...) Figure 68A1, indicated in the diagram, corresponds to either a brief or momentary upward actuation or a downward actuation (also indicated at B1 and again corresponding to a brief or momentary downward actuation). Continuous or incremental up / down shifter positions are achieved by holding the shift knob for a period of time (e.g., equal to or greater than 0.5 seconds), and these positions are identified by shifting actions A2 and B2, respectively.

[0198] Figure 68 It means from Figure 67 A schematic diagram of the shifter position for each of the PDSNR positions in the components. These are divided into separate display representations and include a first representation 496 for shifting from Park to each of the S / D, N, and R positions, wherein there are consecutive instantaneous upward A1 and downward B1 shifting actions. The downward shifting action B1 can be replaced by a continuous downward shifting action B2 to shift to the reverse position.

[0199] The display indicates that 498 corresponds to a shift scheme from the drive position and may include shifting up A1 to drive, or momentarily or continuously shifting down B1 or B2 from the S / D position to shift between neutral and reverse.

[0200] The display indicates that 500 corresponds to a shift scheme from the relevant moving position and includes shifting up A1 or down B1 or B2 to neutral or reverse.

[0201] Display 502 provides an additional description of the shifting force from neutral to S / D (upward shift via A1) or reverse (downward shift via B1).

[0202] Finally, display 504 shows an alternative reverse gear shifter display scheme using the upward shift A1 (e.g., to neutral) or A2 (jump to S / D position) to shift from reverse. The shifter can be activated (A1) or held in the upward position (A2) to advance to the shifter position. Figure 68 In each of the above reference examples, the parking position can only be operated by engaging the parking button.

[0203] Now continue to Figure 69 An exploded view of the steering column of the rotary gear selector assembly according to another embodiment of the invention is provided (see also...). Figure 70 (As shown in the assembly view). The switching assembly in the form of a rod includes each of an upper housing 506 and a lower housing 508, which are configured to assemble with each other, see the engaging protrusions 510 and 512 for the edge configuration of the lower housing 508 in the receiving position (in Figure 60 The middle part is hidden, but... Figure 71 (shown as 514 and 516 in the cross-sectional view), engaging protrusions 510 and 512 are constructed in opposite and aligned positions in the upper housing 506, and the assembly is mounted in such a manner that it is supported on and extends from the steering column (not shown).

[0204] The upper housing 506 also includes a forward-facing slotted hole (see interconnect edge 518) for receiving and partially projecting the knurled outer contour of an associated switching wheel 520, which has a peaked engagement position 522 defined in its outer periphery. A second forward-facing, laterally spaced slotted hole (further defined by edge edge 524) is also constructed in the upper housing 506 for framing a display component 528 (again, including but not limited to, any of TFT, OLED, or segmented versions). As in the previous embodiments, the holes defining edge edges 518 and 524 may also include mounting of bezel window-like portions to provide enhanced finish to the assembly.

[0205] The lower housing 504 also includes an open interior region that receives the reconstructed PCBA 530 (this is further aided by pairs of engagement protrusions 532 and 534 constructed within the interior of the lower housing for securing to the aligned side edges of the PCBA 530). A belt 536 and end connector 538 extend from the PCBA 530 to the base of the assembled rod, such that the belt is supported within the rod (see the internal support rib shown at 540 associated with the lower housing 508), wherein external inputs (e.g., remote return parking sensors, etc.) are transmitted to the PCBA 530 via the belt 536.

[0206] A separate strip 542 also extends from the display component to a connection location on the PCBA 530 for controlling, for example, an LCD segment associated with the display. Separate power lines 544 and 546 with separate end connectors 548 are also described for attachment to the PCBA 530 to provide power to, for example, separately mounted LED elements (not shown) housed in the display component 528.

[0207] A pair of wave springs 550 and 552 are provided, which are aligned with opposite sides of the switching wheel 520, and also include central arcuate protrusions 554 and 556 (see...). Figure 73 The central arched protrusions 554 and 556 are biased against the opposite side stop profile (see in...). Figure 73The diagram further illustrates this through the opposing angled pawl ramps 558 and 560 corresponding to the contact wave springs 550 / 552. Although not clearly shown, the arcuate recessed channel (see [link to diagram]) Figure 69 555 is described in the bottom annular profile of the switching knob 520 for accommodating the abutment portion 557 within the lower housing between the bracket support portions 566 / 568. A circular magnetic element 562 is engaged in a concave side position of the spindle or shaft support 564 of the switching wheel 520. This may again include, but is not limited to, molding the entire switching wheel around the magnetic element.

[0208] A pair of corrugated bracket defining portions 566 and 568 are depicted projecting from the inner corrugated surface of the lower housing 508 for receiving opposing extended shaft portions (also shown as 564, and...). Figure 69 and Figure 71 (Referring further to 564'). The PCBA 530 also includes an angled shelf support 570 and a sensor 572 (e.g., including but not limited to Hall effect sensing sensors, in...). Figure 71 (Depicted in the cross-sectional view) Positioned on the shelf support close to the magnetic element 562, and such that rotation of the switching wheel 520 in any direction causes rotational displacement of the magnetic element relative to the sensor, thereby allowing the relevant processor communicating with the PCBA 530 to issue a shift instruction to the ECU when it determines that the magnetic element has rotated at a certain angle.

[0210] Figure 72 Provided Figure 70 The diagram shows a 180-degree rotation, with the lower housing removed and depicting a PCBA 530 with a combination of a strap 536 and a connector 538 with a switching knob 520, as well as side support wave springs 550 / 552. Figure 73 yes Figure 72 The enlarged view also shows the lower housing removed and depicts a PCBA 530 with a switching knob 520, side support wave springs 550 / 552, and a sensor 572 with proximal positioning.

[0211] Figures 74A to 74CA series of environmental views are described and the ability to integrate the shifter assembly into various locations within the vehicle interior is shown, not limited to the steering wheel (in...). Figure 74A 574 in the middle), steering column or rod (in Figure 74B 576 in the middle), or the dashboard / instrument panel (by Figure 74C (Description of display 578 and switch knob 580 in the text). Figure 75 Further environmental views of the gear shifter integrated into the central console are shown, as referenced by display section 582 and shift knob 584.

[0212] Accordingly, this invention provides a rotatable shifter assembly for vehicles, which provides an operator interface for selecting transmission gears and provides tactile feedback to the operator during gear shifts, such as by passing through an annular stop profile, on which a spring-loaded pawl is biased to travel through the peaks and grooves / valleys of the profile. The shifter assembly provides the operator with single-position (monostable) functionality between each of the park, reverse, neutral, drive, or manual positions, and single-bump operation for shifting between each gear.

[0213] The corresponding direct-to-drive or direct-to-park function is also achieved by keeping the monostable switch in the maximum rotation position at defined time intervals, and the magnetic component mounted at the end of the switch wheel and the associated engagement between the adjacent PCBA sensor facilitate the instructions sent from the relevant processor to complete the required gear shift.

[0214] This shifter design also provides a return-to-park function, which automatically resets the shifter position to the parking position in response to an external signal (such as a door opening) received by the processor installed on the PCBA. Parking lock and neutral lock functions 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 gear shifting.

[0215] 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 shift wheel 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 the steering wheel or pillar and instrument panel (IP) or other locations.

[0216] Furthermore, it is envisioned that the shifter assembly could be reconfigured for use in components other than gear shifting in a vehicle. Therefore, the term "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.

[0217] My invention has been described, and other and additional preferred embodiments will become apparent to those skilled in the art without departing from the scope of the appended claims. The detailed description and accompanying drawings are further understood to support this disclosure, the scope of which is defined by the claims. Although some best modes and other embodiments for carrying out the teachings of the claims have been described in detail, various alternative designs and embodiments exist to practice the disclosure defined in the appended claims.
