Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an opening / closing device for a window glass of an automobile, and more particularly to an automobile window opening / closing device capable of both electric and manual window up / down operations.

(Prior Art) Conventionally, the opening / closing operation of a window glass of an automobile has been performed manually by turning a regulator handle. In this manual window glass opening / closing device, when the window is fully opened, the handle is operated by 5-6. The operation had to be complicated because it had to be rotated once.

In addition, there is a recent automobile equipped with what is called a power window in order to eliminate the troublesomeness of the manual window opening / closing operation. In this system, an electric motor is used as a power source for operating the window up-and-down mechanism, and an occupant of an automobile can open and close the window glass with a single switch.

(Problems to be solved by the invention) However, since this power window uses the electric motor as a power source as described above, for example, when the power of the vehicle is turned off and cannot be turned on due to an accident or the like, the window glass There is a problem that the opening and closing operation of the can not be performed. Also, regardless of whether the power source is good or bad, if the electric motor fails, the window glass cannot be opened or closed at all.

Further, this power window requires a relatively large current because the electric motor needs to be rotated as described above, so that, for example, when the window is opened and closed when the engine is turned off and the engine is at rest, a structural problem occurs in the automobile.

If the car's engine does not turn, the battery cannot be charged with electricity unless the engine is running.Repeating the window glass, which requires a large current when the engine is stopped, as described above, greatly affects the power consumption and causes the battery to rise. Therefore, it may lead to the inability to start the engine again. For this reason, when operating the power window, it is necessary to keep the engine running without endurance regardless of whether the vehicle is running or stopped. This was very uneconomical for those who used a car with a power window.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an automobile window opening / closing device having the advantages of both manual operation and electric operation in the window glass opening / closing device.

(Means for Solving the Problems) The present invention provides an automobile window opening / closing apparatus which is provided with two driving devices, a manual driving device and an electric driving device, and both of which are provided with a follower blocking mechanism by the other driving force to operate the window glass up and down. It is intended to solve the above-mentioned problems by performing the combined use.

That is, the gist of the present invention is an automobile window opening / closing device that raises and lowers a window by swinging a drive arm by a driving force from a manual drive device or an electric drive device. The vehicle window opening / closing device is provided with a driven stop mechanism for preventing rotation when it is received.

(Operation) The vehicle window opening / closing device having the above-described configuration is provided with the manual drive device and the electric drive device, and when the drive force of one of the drive forces is received by the other drive device. Since the device is not driven, only the window glass is moved up and down, so that the window glass can be opened and closed by both manual operation and electric operation.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

First Embodiment In FIGS. 1A and 1B, the door 19 has a window glass 20.
The vehicle window opening / closing device 1 is attached to the vehicle window opening / closing device 1. The vehicle window opening / closing device 1 includes a manual drive device 2, an electric drive device 3, and a drive arm 4.

Here, the driven stop mechanism in the manual drive device 2 will be described.

In FIG. 1A, the manual drive device 2 includes a handle 6
And a casing 7, a spring 8, a handle piece 9 and a gear piece 10. The positional relationship of each is shown in FIGS.
This manual drive device 2 shown in FIG. 2 is when a force is applied from the handle 6 as shown in FIG.
Since a force acts in the direction in which the handle piece 9 contracts and rotates the spring 8, the friction between the inner surface of the casing 7 and the outer surface of the spring 8 becomes small, and the spring 8 becomes rotatable, so that the gear surface 10a of the gear piece 10 is rotated. Can transmit power to.

On the other hand, when a force is applied from the gear piece 10 (arrow G
Force) from the gear piece 10 in the direction of enlarging and rotating the spring 8, the spring 8 expands in the casing 7, and the friction between the inner surface of the casing 7 and the outer surface of the spring 8 becomes large. Therefore, the rotation is suppressed and the force cannot be transmitted to the handle 6.

In other words, the manual drive device 2 can rotate the gear piece 10 from the handle 6, but cannot rotate the handle 6 from the gear piece 10, so that this serves as a driven stop mechanism for preventing rotation.

Next, the driven stop mechanism in the electric drive device 3 will be described.

A switch for turning on and off the motor 18 of the electric drive device 3 is omitted in the drawing.

In FIGS. 1 (a) and (b), 18 is a worm gear 17a.
Reference numeral 15 denotes a motor for driving the motor, and reference numeral 15 denotes a shaft having a worm wheel 16a that meshes with the worm gear 17a and a gear surface 15a that meshes with a gear surface 12a described later.

Since the electric drive device 3 is configured to drive the worm wheel 16a by the worm gear 17a, the shaft 15 can be rotated from the motor 18, but the shaft 15 to the motor 18 can rotate.
Since it is not rotatable, this serves as a driven stop mechanism for preventing rotation.

Hereinafter, the transmission means for transmitting the driving force from the manual drive device 2 and the electric drive device 3 to the drive arm 4 will be described.

In FIGS. 1 (a) to 1 (c), reference numerals 11 and 12 denote gears of different pitch diameters which are pivotally supported at the same center as the drive arm 4, and 11a and 12a are formed on the outer periphery thereof. The gear surface is shown. Both gears 11 and 12 are provided so as to be rotatable relative to each other.

Reference numeral 13 denotes an up-and-down gear that is rotatably supported by the end of the drive arm 4 and has gear surfaces 13a and 14a that mesh with the gear surfaces 11a and 12a. Gear surface 13
Due to the difference in the number of teeth of a and 14a, the gear surfaces 11a and 12a are meshed and fixed when both are stopped.

The present embodiment has the above-mentioned structure, and its operation will be described below.

I. When Opening and Closing the Window Glass 20 by Manual Operation In FIG. 1 (a), if the handle 6 is rotated counterclockwise, the gear 11 receives the force of clockwise rotation via the gear surface 10a. As a result, the upper and lower gears 13 pass through the gear surface 11a.
Will receive a left-handed rotational force.
Since the other gear 12 formed by meshing 13 is stopped by the electric drive device 3, the upper and lower gears 13 are
It can be moved while rotating to the lower side. As a result, the other end of the drive arm 4 is raised and the window glass 20 can be closed to lift the window glass 20.

On the contrary, if the handle 6 is rotated clockwise, the window glass
Can descend 20.

II. In the case of electrically opening and closing the window glass 20 In FIGS. 1 (a) to (c), when the worm wheel 16a is rotated by the rotation of the worm gear 17a of the motor 18, the gear 12 is moved via the shaft 15. It will be rotated. The rotation of the gear 12 causes the upper and lower gears 13 to rotate, but since the manual drive device 2 cannot be rotated from the gear 11, the upper and lower gears 13 move while meshing with the outer periphery of the gear 11, Like the drive unit 2, the window glass 20 can be moved up and down.

As described above, since the window glass 20 can be opened and closed in both the manual drive device 2 and the electric drive device 3, the occupant of the vehicle can perform the opening / closing operation commonly as needed. .

For this reason, for example, when the vehicle is stopped for a long time and relaxed in the vehicle, the window glass 20 can be moved up and down by the manual drive device 2 even when the driver turns off the engine and powers off the vehicle. Therefore, it is very economical.

On the other hand, in the running state, the electric power supply of the engine is sufficient, so that the window glass 20 can be opened and closed by one switch of the electric drive device 3.

[Second Embodiment] Next, a second embodiment of the present invention will be described.

For the sake of convenience of explanation, the explanation of the constitution overlapping with that of the first embodiment is omitted.

In FIGS. 3 (a), (b) and (c), reference numerals 21 and 22 denote gears that are provided at the same center as the drive arm 4 and are rotatable relative to each other. The gear 21 has a gear surface 21a on the outer and inner circumferences. , 21b, and the gear 22 is a gear 2 facing the gear surface 21b of the gear 21.
2a is formed. Between the gear surface 21b and the gear surface 22a, an upper and lower gear 23 that meshes with both gear surfaces is arranged.

Further, the gear surface 22a of the gear 22 is meshed with the gear surface 15a of the shaft 15 so that the electric drive device 3 can drive the gear 22.

The present embodiment has the above-mentioned structure, and its operation will be described below.

I. When manually opening and closing the window glass 20 When a rotational force is applied from the handle 6, the gear 21 is rotated. At this time, the gear 22 is prevented from rotating by the electric drive device 3, so that the upper and lower gears 23 are moved between the gear surfaces 21b and 22a while being rotated in the same direction as the rotation direction of the gear 21. .

The movement of the vertical gear 23 causes the drive arm 4 to swing, so that the window glass 20 is vertically moved.

II. When opening and closing the window glass 20 by electric power If the gear 22 is rotated by the rotation of the motor 18 via the worm gear 17a and the worm wheel 16a, the upper and lower gears 23 receive the rotational force. Since the rotation is blocked by the drive device 2, the upper and lower gears 23 are moved between the gears 21 and 22 in the same direction as the rotation direction of the gears 22 while the upper and lower gears 23 are rotated. Can be done.

As described above, in the present embodiment, since the manual drive device 2 and the electric drive device 3 are integrally configured, the entire vehicle window opening / closing device 1 can be configured in a compact size. It is also convenient to handle in. Further, as shown in FIGS. 4 (a) and 4 (b), from the electric drive device 3 to the gear 12 from the device around the gear piece 10 which transmits the driving force from the device from the manual drive device 2 to the gear 11. When the gear 25 having the gear surfaces 25a26a for transmitting the driving force of the is configured to be rotatable, the shaft 15 of the electric drive device 3 can be omitted, and the number of parts can be reduced. There are advantages.

Since the automobile window opening / closing apparatus 1 of each of the above-mentioned embodiments has a mechanical structure, at least the window opening / closing operation by the manual driving apparatus 2 can be performed even if the electric drive apparatus 3 does not move due to an electrical trouble. In addition, the safety at the time of the trouble is improved.

In the first embodiment, since the gears 11 and 12 are formed with different pitch diameters, the upper and lower gears 13 are fixedly meshed when both gears 11 and 12 are stopped, but the invention is not limited to this. When the drive arm 4 fixing means is used, the gears 11 and 12 may have the same shape.

Further, in each of the above-described embodiments, the rotation preventing mechanism of the manual drive device 2 is made to rotate and expand / contract the spring 8. However, this is not a condition, and other structures may be used.

Although the automobile window opening / closing device is used for the door in this embodiment, it is needless to say that the present invention is not limited to this and can be used for window glass other than the door.

Further, since the details of the present invention can be changed freely within the scope of the invention, the details of the specification change do not matter.

(Effect of the Invention) As described above, the present invention is an automobile window opening / closing device that can be operated both manually and electrically. Therefore, the conventional manual window glass driving operation is complicated and electric window glass is used. A very special effect of providing a car window opening / closing device that solves both problems such as limitation of use conditions in driving operation and arbitrarily selects a driving method under all conditions and can perform suitable window glass opening / closing operation Came to have.

Further, the present invention has an advantage that the switching operation is not hindered by an electrical trouble because it has a structure for mechanically performing the switching differential between the manual and electric driving forces.
