Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a power type window regulator device for changing a manual type window regulator device to a power type window regulator device.

(Prior Art) There are two types of regulator devices for raising and lowering door glass: manual type and automatic type (power type).

As a manual window regulator device, it was introduced in the 1970s.
- As shown in No. 1224, a lift link mechanism consisting of two wooden arms assembled in an X shape is attached to the inner panel of the door, and the link mechanism is connected to the link mechanism by opening and closing it by operating the handle. It is known that the door glass is raised and lowered along a guide. On the other hand, as a power type window regulator device, as shown in Japanese Utility Model Application Laid-Open No. 56-112265, one is known that uses a motor as a driving source instead of the handle.

By the way, when changing the above-mentioned manual type window regulator device to a power type, it is sufficient to remove the handle part and install a drive part with a motor in this part, and this technology has already been proposed in Japanese Utility Model Publication No. 57-15976. has been done.

(Problems to be Solved by the Invention) As mentioned above, in order to change the manual window regulator device to a power type, as shown in Utility Model Publication No. 5.7-15976, a drive unit is installed in the part where the handle used to be. It would be sufficient to install the unit and engage the gear in this unit with the rotating shaft (pinion shaft) that the handle was engaged with, but the motor and gears, etc. must be installed in the 10 unit, and the handle It becomes extremely large compared to . As a result, the interior space is narrowed by the drive unit, resulting in an extremely unsightly appearance, and furthermore, problems such as getting in the way when getting on and off the vehicle occur.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a power type window regulator device that is assembled into a conventional manual type window regulator device, and includes a drive unit equipped with a motor, and a door glass lifting mechanism. It consists of a gearbox incorporating a gear that engages with the part that was engaged with the manual handle, and a wire that connects the pulley in the drive unit and the gear in the gearbox, and the drive unit further includes: The gearbox was placed between the outer panel of the door and the door glass, and the gearbox was placed between the inner panel of the door and the lining.

(Operation) When the motor of the drive unit is driven, the first and second pulleys rotate, and as the pulleys rotate, one end of the wire is wound around one pulley, and the other end is let out from the other pulley. The movement of this wire rotates the gear in the gear box that is engaged with the spiral wire that forms part of the wire, and the rotation of this gear rotates the pinion shaft that forms part of the lifting mechanism. The link mechanism is activated by the rotation of the pinion shaft, etc., and the door glass is raised and lowered.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

20) performs opening/closing and lifting/lowering operations, and this operation causes the door glass (5)' to move through the guide (12), which has a U-shaped cross section.
, (12). As shown in Fig. 4, the power type window regulator device (20) has a drive section (
30), a gearbox (40), and a wire (50) connecting these.

The drive unit (30) includes a motor (31) and a pulley box (
32), and inside the pulley box (32) there is a worm (33) that is rotated by the motor (31), a worm gear (34) that meshes with the worm (33), and a worm gear (34) that rotates integrally with the ohm gear (34). A first pulley (35) and a second pulley (36) are provided, a return spring (37) is housed in the first pulley (35), and the outer circumferential groove of the first pulley (35) is provided with the One end of the wire (50) is wound in one direction (for example, clockwise), and the wire (50) is wound in the outer peripheral groove of the second pulley (36).
0) is wound in the other direction (for example, left-handed), and by driving the motor (31), the wire (50) is wound around one pulley, and the wire (50) is wound from the other pulley. 50) is played out.

By the way, as shown in FIGS. 2 and 3, the drive unit (30) is located between the outer panel (2) at the front position inside the door (1) and the door glass (5) stored inside the door. It is arranged in space at a substantially midway position in the vertical direction. As shown in FIG. 2, the drive unit (30) is attached to the pulley box (32) on the bracket (60) which is fixed to the inner panel (3) together with the stopper link (9).
), and a locking piece (62) having an elastic body (61) fitted to the tip is attached to the bracket (60), and the guide is fixed between the locking piece (62) and the bracket (60). (12) is held in between.

By arranging the drive unit (30) in the relatively wide space formed between the outer panel (2) and the door glass (5) as described above, the space inside the door (1) can be used effectively, In addition, by arranging the drive unit (30) at the front of the space inside the door (1), the drive unit (
30) The impulse acting on can be minimized,
The weight of the bracket etc. can be reduced accordingly, and the drive part (
30) at two locations, that is, the co-fastening portion of the bracket (60) and the locking piece (62), vibrations can be absorbed and the support can be ensured.

On the other hand, the gear box (40) is arranged between the inner panel (3) and the lining (4) and inside the case (70) attached to the inner panel (3), as shown in FIG. A switch box (80) is attached to the inside of the gear case (40).

Here, a nion shaft (71) protrudes from the case (70) when it passes through the gear case (40), and a spline (72) is carved at the tip of this pinion shaft (71). In the case of a manual window regulator, the handle base fits. Further, a gear meshes with the base of the pinion shaft (71) in the case (70), and this gear meshes with the base of the pinion shaft (71).
) meshes with a fan-shaped gear, etc. provided on the arm that makes up the arm.

In addition, there is an ohm gear (41) inside the gear case (40).
and a cylindrical body (42) are housed in the ohmic gear (41), and a deformed hole (43) is formed in the center of the ohm gear (41) as shown in FIG. As shown, it has the same shape as the irregularly shaped hole (43), and the irregularly shaped hole (43) and the base (4
4), the worm gear (41) and the cylinder body (4) are fitted together.
2) rotates in one body. Furthermore, the cylindrical body (4
A spline (45) is carved on the inner circumference of the worm gear (41), and this spline (45) and the spline (72) of the pinion shaft (71) fit together.
The rotation of the pinion shaft (71) is transmitted to the pinion shaft (71).

Moreover, the inner plate (81) of the switch box (80)
A hole with a tooth (83) is formed in the hole, and a tooth (83) is formed on the outer periphery of the boss of the gear box (40) to be inserted into this hole.
A spline (46) is formed which engages the spline (83).

In this way, the gear box (40) is fixed to the inner plate (81) in a state of uneven engagement, so the gear box (40) itself does not rotate as the wire (50) moves, and the wire (50) Breakage and the like are less likely to occur at the part that is pulled into the gear box (40) and the part that is fed out from the gear box (40). Furthermore, since the mounting angle of the gear box (40) can be adjusted, the angle at which the wire (50) is drawn in and fed out can be optimized depending on the model.

On the other hand, the wire (50) is housed in the outer tube (51), and the middle part of the wire (50) is connected to a spiral wire (53) in which a thin wire (52) is spirally wound around the wire (50). This portion of the spiral wire (53) meshes with the worm gear (41) in the gear box (40).

The use of the spiral wire (53) in this way has the following advantages. In other words, the driving force of the motor (31) is transferred to the pinion shaft (
71), a pulley will be used instead of the worm gear (41), but the wire must be wound around this pulley several times to accommodate the amount of wire being fed out and pulled in. It is necessary to make the pulley thicker, which inevitably increases the thickness of the gear box (40), which makes it impossible to place the gear box (40) between the lining (4) and the inner panel (3), and the room Disadvantages arise, such as the gear box (40) protruding significantly inward. However, if the spiral wire (53) is used as a part of the wire (50) as in the present invention, the worm gear (41) can be replaced by the spiral wire (53).
3) The gear box (40) can be made extremely thin because it only needs to be thick enough for one gear to mesh.

In addition, the wire (50) is routed through the drive unit (30).
extends rearward through the lower part of the door (1) and enters the space between the inner panel (3) and the lining (4) through an opening (6) formed at the rear of the inner panel (3);
It passes through this space and is connected to the gearbox (40). By setting the wire (50) to a certain length in this way, the power type window regulator device according to the present invention can be applied to most types of doors without any adjustment.

Here, a door lock release mechanism is provided near the gear box (40), a door lock mechanism is provided at the rear end of the door (1), and a link connecting these levers and the door lock is passed through. The recess for the inner panel (3)
The wire (5) is formed along this recess.
0), positioning and handling of the wire (50) becomes easier.

In the above, when the motor (31) is driven, the drive section (30
), the pulleys (35) and (3B) rotate, and this rotation moves the wire (50).
The movement of the worm gear (41) in the gear box (40) rotates, and this rotation causes the nion shaft (71) to rotate. And, and Nion Shaft (71
) rotates, the elevating mechanism such as the link (11) operates, and the door glass (5) moves up and down along the guide (12).

(Effects of the Invention) As explained above, according to the power type window regulator device according to the present invention, a manual type window regulator device can be changed to a power type without any modification, and when the manual type window regulator device is changed, the power type can be driven. The parts etc. do not protrude greatly toward the indoor side, and the problem of pinching the indoor space does not occur.

In addition, it is extremely convenient as it can be used with any type of regular manual window regulator device.
