Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to fraud in closing the window υ11 of a car at one's own expense.

In automobiles, for example, a so-called power window regulator that uses an electric motor to open and close a door glass has conventionally engaged a hinge rotated by the motor with a rack provided on the arm side, and the arm is rotated by the rotation of the motor. A method called the Rikku IX arm type (or rack-and-binion type), in which the window crow lifts 1+11 in the arm qnoF group building 1, or a spiral p-tooth on the outer periphery of the wire. Using a shaped flexible geared wire, a gear rotated by a motor is meshed with the protruding teeth of the geared wire, and the geared wire slides in the longitudinal direction by the rotation of the motor and is connected to the geared wire.
Generally, a gad wire system is used in which the wire is lowered.

However, the disadvantage is that there are a lot of arm type Mononoke IflS products, and the weight is increased, and the geared wire type Mononoke has a flexible geared wire and an outer that movably supports it. Not only does it have the disadvantage of making abnormal noises due to contact with the tube, or causing the operation to get stuck, resulting in a poor feeling during operation, but also Self-X arm tie “,
A reduction gear consisting of a combination of a worm gear, a worm wheel, etc. must be interposed between the gadwire type double-well motor and the pinion and float rotated by it, so that the motor assembly does not become large. It has the disadvantage that it is not.

An object of the present invention is to provide a power window regulator that can eliminate all of the conventional drawbacks as described above, and will be described below with reference to the accompanying drawings.

FIG. 1 shows a first embodiment of the present invention, in which 1b is a medical glass, 2 is a bracket attached to the vicinity of the lower edge of the medical glass 1, and 3 is an electric motor attached to the medical examination bracket 2. be.

On the other hand, the inner panel of the door (not shown) has a male screw member 6 with a male screw on the outer circumferential surface via an earthwork platen 4.1.
is mounted on a line that almost coincides with the lifting locus of the window glass 1, and a guide member 2a provided on the bracket 2 on the front F window glass 1 side is fitted into the sliding control to control the lifting and lowering operation of the glass 1. The guide rail 7 that guides the brackets 4 and 5
installed between.

For example, as shown in FIG. 3, the electric motor 3 has a motor shaft 31 formed in the shape of a hollow pipe, so that the male threaded member 6 can be freely inserted into the motor shaft 31 with some margin, and A nut, that is, a female thread member 32, which is screwed into the male thread member 6, is integrally attached to both ends (or only one end is fine) of the motor shaft 31, and as shown in FIG. The motor 3 is attached to the window glass 1 (III bracket 2) with the male screw end 6 screwed into the T screw member 32 and passed through the hollow motor shaft 31.
(3) It is not fully supported.

FIG. 3 shows a 33-piece motor case, a 34-piece magnet provided on the inner peripheral surface of the case, a 35-piece rotor integrated with the motor shaft 31, a 36-piece brush portion, and a 37-piece thrust bearing number.

As the screw member 6, it is desirable to use a flexible geared wire in which protruding teeth are formed in a spiral shape on the outer periphery of the wire.

In the above tlAt imaginary, operate the switch not shown! ! When the motor shaft 31 of the electric motor is driven in the forward or reverse direction, the electric motor 3 is connected to the male screw capital side 6 and 1 and the screw member 32.
The window glass 1, which is connected to the electric motor 3, is moved up and down by the electric motor 3, and is guided by the guide rail 7 together with the electric motor 3 to move up and down.

In this case, if a flexible geared wire is used as the Mt screw member 6 as described above, even if there is some error between the trajectory of the male threaded BIS material 6 and the window glass 1, the geared wire will sag somewhat and the error will be compensated for. The window glass can be moved up and down smoothly by absorption, and even in the case of curved glass, the geared wire bends and follows the direction intersecting one surface of the hemp glass to perform smooth operation.

In addition, in Fig. 1, both sides of the window glass 1 (jl, l gis
If the door is slidably supported by a sash on the door side, the nitride glass guide mechanism using the guide rail 7 and guide member 2a is not necessary.

FIG. 2 shows a second embodiment of the present invention. In this example, a threaded rod having a predetermined full property is used as the male threaded member 6, and the male threaded member 6 itself functions as a feed screw and a window glass. 1, the guide rail 7, guide member 2α, etc. in FIG. 1 are omitted.

When the embodiment of FIG. 2 is used as an opening/closing device for a curved crow as shown in the figure, the curved external threaded member 6
The internally threaded member 3:1 is connected to the outer peripheral surface or inner peripheral surface of the tip of the hollow motor shaft 31 via a universal joint so that the internally threaded member 32 can be freely oscillated. However, if the female screw member 32 is provided only at the upper end of the motor shaft 31, it may not necessarily be possible to swing the head. ! It can be adapted to the 9 songs of the screw section vl'6.

In FIG. 2, numbers other than 81 above are the same as 11 and I, and the same symbols as in FIG. 1 represent the same hIS fraction codes.

Embodiment P above shows an example in which a female screw member 32 is attached to one end or both ends of a motor@31, as shown in FIG. ' may be integrally formed, and the male threaded member 6 may be screwed into this female threaded capital 32' to extend through 11 degrees. In FIG. 4, the same reference numerals as in FIG. 3 represent the same parts.

υ According to the present invention, as described above, an electric motor consisting of a hollow shaft with a female screw thread is used to cool the motor shaft, and the surface control motor is attached to a room glass, and is attached to a fixed panel such as a door inner panel. The male screw member provided on the side is assembled to the hollow shaft of the electric motor in a state in which the screw capital and the screw capital are aligned, and the electric motor is By moving along the fito screw member to open and close the window glass, the reduction gear required in conventional power window regulators is completely unnecessary. Compared to the gear type, it does not require an outer tube, which eliminates all problems such as abnormal noise and poor operating feeling, and it is less expensive and easier to assemble. It is possible to have a large amount of practical effects.

The present invention can be applied not only to the door compartment glass of a motor vehicle, but also to the rear quarter window of a motor vehicle, the front of the roof window of a sunroof vehicle, etc., and as an opening/closing tube for all kinds of side parts of a motor vehicle. Needless to say.
