Abstract
A window regulating device for moving a vehicle window between an open position and a closed position. The window regulating device comprises a threaded rod that is vertically secured to the vehicle door, and said threaded rod extends through a radius of curvature of a travel path of the vehicle window. An electric motor comprising a hollow axle, said axle core being at least partly tapped. The threaded rod extends through said tapped axle, and the threaded rod engages the tapped axle in a screw and nut manner. The vehicle window is secured to the motor housing, either directly or by way of a connecting member. When the electric motor is energized, the tapped axle of the motor spins, and the electric motor and the attached vehicle window travel together along the fixedly secured threaded rod.
Description
FIELD OF THE INVENTION
The invention relates to a device for opening and closing the window of a vehicle. More specifically the invention relates to a power-window regulator employing the use of an electric motor to convert rotational motion of the motor-axle into linear motion along a vertical member.
BACKGROUND OF THE INVENTION
The invention pertains generally to power window regulators for vehicle doors.
More specifically the invention relates to a device for opening and closing the window of a vehicle door using an electric motor for generating rotational motion and converting said rotational motion into linear motion.
The device comprises and electric motor, said motor comprising an axle, said axle comprising a hollow core, said hollow core being at least partly tapped such that a threaded rod, of matching thread, penetrates the axle core and extends beyond the axle in both directions, and as the electric motor is energized the axle spins and the electric motor and vehicle window both ascend and descend along the vertically affixed threaded rod.
Currently there are 2 main types of window regulators employed in the automotive industry: a) arm and sector regulators, and b) cable and drum regulators. Both types use a conventional electric motor to generate rotational motion about the motor axle. Both types use a reduction gear to generate rotation about a second axle of rotation. The arm and sector regulators, in addition to the electric motor and worm-gear assembly, require a wide range of stampings including the main arm, base-plate, lifter plate, connecting arms, sector plate etc including expensive tooling. The cable and drum regulators, in addition to the electric motor and worm-gear assembly, require a wide range of stampings and plastic moldings including a minimum of one rail, mounting brackets, sliding member(s), a Bowden cable system and accompanying components, including expensive tooling.
Both systems are time consuming and expensive to: a) design, b) build tooling for, c) manufacture, d) assemble, e) package, f) mount to door, etc.
The invention possesses numerous advantages over know window regulators. The invention is a direct drive device where the rotating motor axle acts directly on the vertical member without relying on a reduction gear or worm gear. The vertical member is a threaded rod which penetrates through the center of the motor axle, said motor axle is concentrically hollow and tapped, and extends in both directions beyond the axle. As the tapped motor axle spins, the electric motor, a connecting member and the vehicle window all travel along the threaded rod. Since the tapped axle is at least partly tapped, and may be preceded and succeeded by clearance openings for passing a threaded rod of considerable curvature, it is possible to apply this device for use on windows which are of considerable curvature.
Thus it is evident that the invention provides a novel window regulator, said window regulator comprising fewer parts, simpler to manufacture, requiring a reduced design and tool-making constraint, reduced assembly time, smaller to package, lighter in weight and more cost efficient over current designs.
DESCRIPTION OF PRIOR ART
It is known in the prior act to provide a window regulator comprising a threaded rod as the vertical member and engaging said threaded rod with an electric motor to generate window movement along the threaded rod.
US patent number 5,012,613 to Shuji Sekine on May 7, 1991, uses a permanently fixed electric motor and a vertically secured threaded rod, including a rail system and a method of linking the motor to act on the driving nut along the lead screw.
US Patent Number 3,014,715 to Jack E. Martens on December 26, 1961, uses an electric motor in a fixed horizontal position to rotate a vertically mounted straight threaded rod, said rotation of the rod causes a screw and window to ascend and descend the height of the threaded rod.
US Patent Number 2,649,300 to James M. Launder on August 18, 1953, uses an electric motor and a sleeve comprising a screw, and said motor is coupled to said sleeve by a reduction gear and both motor and sleeve (and window) travel along a curved threaded rod in both directions.
US patent Number 2,311,972 to Emory Glenn Simpson on February 23, 1943, uses an electric motor, a gearing mechanism external to the threaded rod, a screw-type member acted on by the gearing mechanism, and a jack-screw mechanism for lifting and lowering the vehicle window.
SUMMARY OF THE INVENTION
The invention pertains to a power window regulator including a threaded rod and an electric motor comprising a rotating axle, said axle comprising a hollow core, said hollow core being at least partly tapped such that the threaded rod penetrates the full length of the inside of the tapped axle and the thread of the threaded rod engages the tap of the tapped axle, and said rod extends beyond both ends of the tapped axle core. The threaded rod is mounted vertically at each end to the vehicle door. Method of engagement between the threaded rod and the tapped axle of the electric motor is similar to that of a nut and screw, the nut being the tapped axle and the screw being the threaded rod. The threaded rod extends through a radius of curvature of a travel path of a vehicle window.
The window is mounted either directly to the motor housing or by a connecting member to the motor housing. As the electric motor is energized, the tapped axle spins and the electric motor and attached window both ascend and descend along the threaded rod. For windows of curvature, the tap of the tapped axle may be preceded and/or succeeded by clearance holes for passing a curved threaded rod through the axle core without having said threaded rod jamming into the inner axle core walls.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig-1 illustrates a conventional (brush-type) electric motor 1, including a rotating inner axle 2, a stator 3, wiring 4, armature 5, permanent magnet 6 and motor housing 7.
Fig-2 illustrates the tapped axle motor 8 including a threaded rod 9 extending the full length of the tapped axle 10, said threaded rod 9 engaging the tap 11 of said tapped axle motor 8, and said tapped axle 10 comprising a hollow axle core 12.
Fig-3 illustrates the cross section of Fig-2 along line AA of the tapped axle motor 8, including the tap 11 of the hollow axle core 12, through which the threaded rod 9 will pass unobstructed. Radially disposed bushings 13 at each end of the tapped axle 10 are positioned between the tapped axle 10 and the motor housing 7.
Fig-4 illustrates the interaction between said threaded rod 9, vertically mounted in a vehicle door 31, said threaded rod 9 extending through the tapped axle 10 of the tapped axle motor 8. The vehicle window 14 is mounted to the tapped axle motor 8 by a connecting member 28. To conserve space along the thickness of the vehicle door, the permanent magnets 6 are axially aligned with the bottom edge of the vehicle window 14.
Fig-5 is a cross section of a tapped axle motor for use with a curved threaded rod 25. The tapped axle 10 comprises a tap diameter 15, a tap length 16 along which said curved threaded rod 25 engages said tapped axle 10, and clearance holes of clearance length 17 and clearance diameter 18 at each end of the tapped axle 10. Said clearance holes ensure that the curved threaded rod 25 engages the tap 11 of the tapped axle 10 without obstruction from the axle-core walls 12.
Fig-6 further illustrates a curved threaded rod 25 engaging a tapped axle motor 8, including the tapped axle's axis of rotation 29 and the curved threaded rod's curvature 21.
Note the deviation from a straight path between the tapped axle's axis of rotation 29 and the curved threaded rod's curvature 21. Clearance holes of Fig-5 are intended to compensate for said deviation to prevent the curved threaded rod 25 from jamming into the axle-core walls 12. The motor housing comprising a can 19 and an end-wall 20 are also illustrated.
Fig-7 is a 3 dimensional cross section of the tapped axle 10, including the tap 11, and a clearance wall 22 at each end of the tapped axle 10.
Fig-8 illustrates a motor end-wall 20 and a mounting member 28 combined to make one mounting unit 26. The mounting unit 26 is connected to said electric motor 8 and comprises mounting arms 30 as in Fig-9. Said mounting arms 30 extend in opposite directioris from the curved threaded rod 25. Said mounting arms 30 extend parallel to the bottom of the vehicle window 14 as in Fig-10.
Fig-11 illustrates a vehicle door 31 housing the window regulator 24.
Including the vehicle window 14, connecting member and end-wall unit 26, said curved threaded rod 25, said electric motor 8. As the electric motor 8 is energized, the tapped motor axle 10 rotates, causing the tapped-axle motor 8 and the mounting member 26, and the attached vehicle window 14 to travel along the curved threaded rod 25 in a to-and-fro motion.
The vehicle window 14 prevents the electric motor 8 from rotating about the threaded rod 25. The curved threaded rod 25 is mounted vertically in the vehicle door 31. The curved threaded rod 25 is mounted in the general horizontal center of the vehicle door 31. The end-wall unit 26 (the mounting member) provides centered and symmetrical support to the vehicle window 14. The vehicle window 14 is mounted to the window regulator 24 along the lower end 32 of said vehicle window 14.
Fig-12 illustrates how the can 19 of the electric motor housing and the mounting member 28 may be cast as one unit.
Fig-13 illustrates the can of the electric motor housing 19, end-wall 25 of the electric motor housing and the mounting member 28 as three separate units.
Fig-14 illustrates a cross section of the vehicle door 31 with the window 14 in the up position. The vehicle window 14 is connected to the mounting member 28, said mounting member 28 is attached to the tapped-axle motor 8. Said vehicle window 14 and said mounting member 28 and said tapped-axle motor 8 travel vertically along the curved threaded rod 25. Said threaded rod 25 is attached and immobilized at each end by mounting units 27 to the vehicle door 31.
Fig-15 illustrates a cross section of the vehicle door with the window in the down position.
Said vehicle window 14 and said mounting member 28 and said tapped-axle motor 8 have traveled vertically downward along the curved threaded rod 25 to a lower position thus placing the vehicle window 14 in the open position.
In applications where availability of space inside the vehicle door is a concern, a narrow mounting member 28 of Fig-16 may be used. Said narrow connecting member 28 is particularly suitable for smaller type windows.
To provide guiding functionality, Fig-17 illustrates how a guiding member 33, comprising a rail or a rod or other, is mounted parallel to the threaded rod 9 or 25, and said guiding member 33 is slidingly engaged by a connecting member 34 (or a modified mounting member 28) to provide support and guiding during motor 8 travel.
Fig-18 illustrates how a plurality of tapped axle motors 8 may engage a single threaded rod 9 to transfer a vehicle window 14 or other unit 35 along said single threaded rod 9 or 25.
The invention relates to a device for opening and closing the window of a vehicle. More specifically the invention relates to a power-window regulator employing the use of an electric motor to convert rotational motion of the motor-axle into linear motion along a vertical member.
