This invention relates generally to multi-functional apparatuses and specifically to a gear drive window wiper and multi-function electric motor for use in an automotive vehicle.
Almost all automotive vehicles have a single or a pair of windshield wiper assemblies. These assemblies traditionally include rubber wiper blades mounted upon claw brackets. These claw brackets are attached to wiper arms mounted upon rotating shafts. These shafts are either directly driven by electric motors or driven by a single electric motor which actuates series or parallel-coupled four-bar linkage mechanisms. It is further known to provide a wiper system in combination with a wash device, to clean headlamps for automotive vehicles.
It is also common to employ a window wiper assembly for cleaning rear windows of automotive vehicles. Typically, these types of rear window wiper assemblies include a wiper blade mounted upon a bracket which is coupled to a wiper arm. The wiper arm is attached to a wiper shaft rotatably driven in a cyclical oscillating manner by a helical gear. A reversible, fractional horsepower, dc electric motor serves to actuate the helical gear through an armature shaft-mounted worm gear enmeshed therewith. This type of rear window wiper arrangement is usually mounted upon a pivoting liftgate of a minivan, station wagon, sport-utility vehicle or the like. Examples of conventional window wiper assemblies and motor mechanisms are disclosed within the following U.S. Pat. Nos.: 4,893,039 entitled "Windshield Wiper Motor" which issued to Isii on Jan. 9, 1990; 4,878,398 entitled "Driving Device for Window Wiper of Motor Vehicles" which issued to Heinrich on Nov. 7, 1989; 4,336,482 entitled "Rear Window Wiper Motor Control" which issued to Goertler et al. on Jun. 22, 1982; 4,259,624 entitled "Arrangement for Wiping a Vehicle Window" which issued to Seibicke on Mar. 31, 1981; 3,694,723 entitled "Motor Vehicle Windshield Wiper Having a Parking Position Outside the Wiper Area" which issued to Schneider et al. on Sep. 26, 1972; and, 3,665,772 entitled "Windshield Wiper Motor Link Depressed Park Mechanism" which issued to Beard et al. on May 30, 1972. All of these patents are incorporated by reference herewithin.
Some conventional vehicles also provide a rear window release lock or latch, actuated by a solenoid, which can be unlocked to allow for upward pivotal movement of the rear window in relation to the otherwise stationary liftgate. In combination therewith, a separate liftgate lock is often mounted upon the liftgate door for fastening the liftgate to the body to prevent inadvertent pivotal opening. This liftgate lock is traditionally operated by manual key or handle rotation, or through a separate electric motor or solenoid.
Recently, a multi-functional apparatus employing an intermittent motion mechanism has been proposed. A single electromagnetic device selectively causes movement of the intermittent motion mechanisms thereby moving mechanical devices coupled thereto. In a specific embodiment, the armature shaft of an electric motor rotates a worm gear segment which then drives a helical gear mounted in a gear housing. Via a series of pins, cams and gears, also mounted in the housing, this input can be made to drive selectively two or three intermittent rotary motion mechanisms according to the rotary position of the helical gear. Mechanical devices which are coupled to the intermittent rotary motion mechanisms, e.g., a rear window wiper, a liftgate lock and a liftgate window release lock, are therefore operated according to the positional range of oscillation or movement of the helical gear. In this way, the number of electromagnetic devices, or motors, required to be fitted to a vehicle liftgate is reduced. An example of this apparatus is disclosed in U.S. patent application Ser. No. 08/430,388 to Zimmer et al. which was filed on Apr. 28, 1995 now U.S. Pat. No. 5,841,249, the entire disclosure of which is hereby incorporated by reference.
Additionally, a multi-functional apparatus employing an electromagnetic device has been proposed. To save weight and space and reduce costs in a vehicle, a multi-functional apparatus is used in place of a plurality of single-function devices. The multi-functional apparatus employs a single electromagnetic device to selectively actuate a plurality of intermittent motion mechanisms, thereby operating mechanical devices attached thereto. In a specific example, a reversible dc electric motor selectively drives a rear window wiper via a transmission, a clutch and a driven shaft. By rotating the transmission member beyond the rotational range for operating the wiper, drive to the wiper is disengaged and a locking mechanism for the rear window or liftgate can also be actuated by the rotating transmission member. In another aspect, a single electric motor selectively actuates three intermittent motion mechanisms thereby causing three mechanical devices coupled thereto to operate (e.g., rear window and liftgate locking mechanisms and a window wiper). An example of this apparatus is disclosed in U.S. patent application Ser. No. 08/431,148 to Maue et al. which was filed on Apr. 28, 1995 and is now U.S. Pat. No. 5,694,812.
Finally, a control system for an automotive vehicle multi-functional apparatus has been proposed. A control system for an automotive vehicle multi-functional apparatus employs an electronic control unit operably controlling a rear window wiper assembly. In another aspect, an electronic control unit is operable as a multiplexed rear node for controlling a variety of liftgate devices and functions. electromagnetic device. The multi-functional electromagnetic device uses intermittent motion mechanisms to selectively operate differing devices driven therefrom. A method of operating the electronic control unit is also provided. An example of this system is disclosed in U.S. patent application Ser. No. 08/431,149 to Maue et al. which was filed on Apr. 28, 1995 and is now U.S. Pat. No. 5,764,010.
In accordance with the present invention, the preferred embodiment of a multi-functional apparatus employs a gear drive window wiper and multi-function electric motor. The electric motor selectively causes movement of an intermittent motion mechanism thereby moving a mechanical device coupled thereto. In another aspect of the present invention a pair of intermittent rotary motion mechanisms are selectively rotated by a single reversible electric motor. In a further aspect of the present invention, a single electric motor selectively actuates three intermittent rotary motion mechanisms thereby causing three mechanical devices coupled thereto to operate. In a still further aspect of the present invention, one intermittent rotary motion mechanism is actuated when the electric motor is operated in a first direction, and the other two intermittent rotary motion mechanisms are actuated when the electric motor is operated in a second direction, the second direction being opposite the first direction. In yet another aspect of the present invention, it is impossible to actuate one intermittent rotary motion mechanism when the other two intermittent rotary mechanisms are being actuated.
The multi-functional apparatus of the present invention is advantageous over conventional systems since the present invention combines many different functions into a single apparatus. For example, the multi-functional apparatus of the present invention replaces the traditional separate rear wiper motor, liftgate lock motor and rear window latch solenoid. Accordingly, the multi-functional apparatus significantly reduces the piece cost, assembly cost, part proliferation and handling costs, wiring costs, and battery current consumption as compared to conventional constructions. Furthermore, the multi-functional apparatus of the present invention significantly reduces weight and packaging space requirements while increasing the electrical and mechanical reliability of the affected systems. Objectional motor and solenoid noises are also reduced. Moreover, the present invention provides a means for mechanically locking the intermittent motion mechanisms and devices coupled thereto in fixed positions. Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.

An automobile vehicle, such as a minivan, station wagon, sport utility vehicle or the like, has a rear liftgate door which can pivot about an upper pair of hinges coupled to the vehicle body structure. When the liftgate is pivoted to an open position, a cargo space is accessible from behind the vehicle. Such a liftgate is shown in FIG. 1. Liftgate 1 has a rear window or backlite 2 pivotable between a closed position, substantially flush with the outer surface of liftgate 1, to an open position about upper hinges. A pair of pneumatic cylinders 3 and 4 act to push window 2 toward the open position when a lower portion of window 2 is released. The preferred embodiment of a gear drive window wiper and multi-function electric motor 5 of the present invention is mounted upon an outer surface of liftgate 1. A majority of apparatus 5 may be hidden by an interior exterior trim panel (not shown). Apparatus 5 primarily includes a central drive and power transmission unit 6, a window wiper assembly 7, a window release latch or lock 8, and a liftgate lock 9, all of which are mounted upon liftgate 1. Examples of such locks (employing separate solenoids or motors, which would be removed in order to couple the lock mechanism for use with the present invention) are disclosed within the following U.S. Pat. Nos.: 5,222,775 entitled "Power Operated Latch Device for Automotive Back Door" which issued to Kato on Jun. 29, 1993; 4,422,522 entitled "Inertial Lock for Vehicle Door Latch" which issued to Slavin et al. on Dec. 27, 1983; and, 3,917,330 entitled "Electric Lock Release" which issued to Quantz on Nov. 4, 1975, the entire specifications of which are incorporated herein by reference.
The construction of central drive and power transmission unit 6 is best illustrated in FIG. 2. An electric motor 119 is of a conventional 12 volt fractional horsepower, dc electromagnetic variety having a metallic motor housing 10 within which are stationary permanent magnets (stator) 11, a rotatable armature 12 with wire windings, a rotatable armature shaft 13 joined to armature 12, a commutator 14 electrically connected to the wire windings and rotatable with armature shaft 13, a brush card assembly 15 and various electronic components, bushings and retainers. A worm gear segment 16 is provided upon a portion of armature shaft 13 extending beyond motor housing 10.
A gear housing 17 is also provided for receiving worm gear segment 16 and the immediately adjacent portions of armature shaft 13. A first worm gear 18 is also housed and rotatably journalled within gear housing 17. Gear housing 17 is preferably made from cast aluminum. A plurality of knurled steel cross shafts 19 are press fit or otherwise attached within machined openings of gear housing 17. The placement of these openings in relation to each other is important. Pins 19 can alternatively be molded as part of plastic gears and cams.
Referring specifically to FIGS. 3a-3b, first worm gear 18 has an external set of helically oriented teeth projecting entirely therearound for meshing with worm gear segment 16. A second gear 20 is mounted upon a face of first worm gear 18 for rotating therewith. It is important to note that the rotation of second gear 20 is dependent on first worm gear 18. In other words, second gear 20 can not rotate without first worm gear 18 rotating simultaneously. Second gear 20 has an external set of helically oriented teeth projecting a portion therearound for meshing with third gear 21. Second gear 20 also has a toothless area or toothless gear portion 22 that does not mesh with third gear 21. This toothless gear portion preferably includes a raised lip portion 22a. This raised lip portion 22a preferably engages with surface 24 of stop 23, as will be fully explained below. Toothless gear portion 22 comprises about 5 to about 270 degrees of the 360 degree circle that defines a periphery of second gear 20. In a preferred embodiment of the present invention, toothless gear portion 22 comprises about 99 degrees of the 360 degree circle that defines a periphery of second gear 20. First worm gear 18 and second gear 20 are coaxially aligned for rotation about their common cross shaft 19. A drive pin 37 having a driving interface surface projects from a face of first worm gear 18 at a height below the cross shaft 219 so as to allow first worm gear 18 to rotate freely about third gear 21.
Referring specifically to FIGS. 4a-4c, third gear 21 has an external set of helically oriented teeth projecting entirely therearound for meshing with the teeth of the second gear 20. Third gear 21 also has a protuberance or stop 23, preferably on the top surface of gear 21, projecting horizontally outward away from the central axis of third gear 21. Stop 23 is comprised of two side surfaces 24 and 25 and a rear surface 26. Surface 24 is comprised of a relatively smooth surface and has a curvature which is compatible with the curvature of toothless gear portion 22 of second gear 20. In other words, toothless gear portion 22, specifically raised lip portion 22a, is able to smoothly engage and slide by surface 24 without any enmeshment occurring between the two. Additionally, this feature aids in preventing third gear 21 from falling out of proper position. Preferably, the radius of stop 23 is equal to the radius of toothless gear portion 22. Stop 23 is configured in such a manner as to allow first worm gear 18 and second gear 20 to rotate freely about third gear 21. The primary purpose of stop 23 is to provide a means for allowing rotation of first worm gear 18 and second gear 20, but to prevent the simultaneous rotation of third gear 21. Thus, by allowing rotation of first worm gear 18 and second gear 20, various intermittent rotary motion mechanisms coupled thereto can be actuated, while at the same time preventing the actuation of any intermittent rotary motion mechanisms which are coupled to third gear 21. Stop 23 prevents rotation of third gear 21 by physically abutting against an interior surface of gear housing 17. Thus, if third gear 21 attempts to rotate clockwise from its position in FIG. 2, stop 23 will immediately be urged against, or abutted by the interior wall of gear housing 17. In this position, apparatus 5 is ready to engage in the actuation of the other intermittent rotary motion mechanisms coupled to the other gears, preferably first worm gear 18.
The second and third intermittent rotary motion mechanisms 27 and 28 cooperate with first worm gear 18 and its associated drive pin 37. Second and third intermittent rotary motion mechanisms 27 and 28 can comprise a window release latch actuator or a liftgate unlock/lock actuator, respectively. However, it should be appreciated that any number or type of various intermittent rotary motion mechanisms can be coupled to first worm gear 18. In accordance with one embodiment of the present invention, second and third intermittent rotary motion mechanisms 27 and 28 are actuators that are comprised of spring-biased lever systems. However, it should be appreciated that any number or type of suitable devices may be employed as actuators for the intermittent rotary motion mechanisms. Thus, when one lever section, 29 or 30, respectively, is actuated, either by raising, lowering, extending vertically, or extending horizontally that lever section, a force is transmitted to the lower lever section, 31 or 32, respectively, which actuates the lock, unlock, or unlatch function of the window release latch or lock 8 or the liftgate lock 9, respectively.
In accordance with one embodiment of the present invention, it is envisioned that an output shaft is rotatably connected, through various mechanical devices such as gears, cams, pinions, to the cross shaft 219 of third gear 21. The output shaft would then be connected to a wiper arm, which would house or receive a wiper blade, preferably made of rubber. In response to rotation of third gear 21, the output shaft would transfer this rotary motion eventually to the wiper arm, thus allowing the wiper blade to wipe the window of the automobile in an arcuate and oscillating manner. The output shaft, the wiper arm, and the wiper blade are generally referred to as the wiper assembly. The wiper assembly is generally referred to as an intermittent rotary motion mechanism, because of its ability to actuated only when required or needed.
Referring now to FIG. 2, the operation of the window assembly 7 will now be described. In this position, the wiper assembly is said to be in a parked position, or alternatively, in a park position. As is clearly illustrated, stop 23 is abutting up against an interior wall of gear housing 17. In order to begin the wiping operation, an actuator, typically on the instrument panel or other control panel of an automobile is actuated. This causes electric motor 119 to energize stator 11, which in turn causes armature 12 to rotate, which in turn causes armature shaft 13 to rotate, which in turn causes worm gear segment 16 to rotate. As worm gear segment 16 rotates it causes first worm gear 18 to rotate clockwise in the direction of arrow A. As previously discussed, the rotation of first worm gear 18 also causes second gear 20 to rotate. The teeth of second gear 20 engage the teeth of third gear 21 causing third gear 21 to rotate counterclockwise in the direction of arrow B. As third gear 21 rotates, the window assembly 7, which is attached to the cross shaft 219 of third gear 21, also rotates, thus causing the wiping operation of the window. Third gear 21 continues to rotate counterclockwise until a surface of the stop 23 abuts an interior wall of gear housing 17, probably in area designated as 36. When this occurs, electric motor 9 reverses polarity, and rotates first worm gear 18 counterclockwise, which then causes second gear 20 to rotate counterclockwise, which then causes third gear 21 to rotate clockwise, thus returning third gear 21 to the parked position. This is generally referred to as the return stroke or the return wipe stroke. This entire operation can then be repeated (e.g., in rainy conditions) or the wiper assembly can then be shut off (e.g., once the rainy conditions have subsided).
The operation of the liftgate unlock/lock function and the window release latch function will now be described with reference to FIGS. 5-10. Referring specifically to FIG. 5, first worm gear 18 is rotated counterclockwise in the direction of arrow B. Second gear 20 also rotates counterclockwise in the direction of arrow B'. However, because toothless gear portion 22 is rotating against surface 24 of stop 23, there is no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 rotates, drive pin 37 is urged up against lever portion 30 in preparation for the actuation of the unlocking function of liftgate unlock/lock mechanism 9.
Referring specifically to FIG. 6, first worm gear 18 is further rotated counterclockwise in the direction of arrow C. Second gear 20 also rotates counterclockwise in the direction of arrow C'. There is still no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 further rotates, drive pin 37 is urged further up against lever portion 30 actuating the unlocking function of liftgate unlock/lock mechanism 9. The actuation is caused by lever portion 30 transferring the force of drive pin 37 downwardly toward lever portion 32 by means of a pivot pin 34. This downward force causes lever portion 32 to extend horizontally outward, thus actuating the unlocking function of liftgate unlock/lock mechanism 9.
Referring specifically to FIG. 7, first worm gear 18 is still further rotated counterclockwise in the direction of arrow D. Second gear 20 also rotates counterclockwise in the direction of arrow D'. There is still no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 still further rotates, drive pin 37 passes lever portion 30. However, lever portion 30 does not return to its initial position as shown in FIG. 4, but rather assumes a position in between its initial position and its actuation position. Drive pin 37 is now urged up against lever portion 29 in preparation for actuating the window release latch function of window release latch mechanism 8.
Referring specifically to FIG. 8, first worm gear 18 is yet still further rotated counterclockwise in the direction of arrow E. Second gear 20 also rotates counterclockwise in the direction of arrow E'. There is still no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 yet still further rotates, drive pin 37 is urged further up against lever portion 29 actuating the window release latch function of window release latch mechanism 8. The actuation is caused by lever portion 29 transferring the force of drive pin 37 downwardly toward lever portion 31 by means of a pivot pin 35. This downward force causes lever portion 31 to extend vertically downward, thus actuating the window release latch function of window release latch mechanism 8. At this point the polarity of electric motor 119 is reversed in preparation for returning first worm gear 18 and second gear 20 to the park position.
Referring specifically to FIG. 9, first worm gear 18 is rotated clockwise in the direction of arrow F. Second gear 20 also rotates clockwise in the direction of arrow F'. However, because toothless gear portion 22 is rotating against surface 24 of stop 23, there is still no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 rotates, drive pin 37 is urged up against lever portion 30 in preparation for the actuation of the locking function of liftgate unlock/lock mechanism 9.
Referring specifically to FIG. 10, first worm gear 18 is further rotated clockwise in the direction of arrow G. Second gear 20 also rotates clockwise in the direction of arrow G'. There is still no rotation of third gear 21, thus there can be no actuation of the wiper assembly 7. As first worm gear 18 further rotates, drive pin 37 is urged further up against lever portion 30 actuating the locking function of liftgate unlock/lock mechanism 9. The actuation is caused by lever portion 30 transferring the force of drive pin 37 downwardly toward lever portion 32 by means of pivot pin 34. This downward force causes lever portion 32 to extend horizontally inward, thus actuating the locking function of liftgate unlock/lock mechanism 9. First worm gear 18 continues its clockwise movement until it returns to the park position of FIG. 2.
