Description

[Detailed description of the invention] The present invention is such that the roof spaces [1] divided by rain gutters can be closed by an electric motor through a compression-resistant cable with a movable lid, and the electric motor can close the roof spaces [1] divided by rain gutters. drive a pinion that is attached to the roof of the vehicle in front of the front of the vehicle and engages with the cable via an intermediate transmission, and this first drive pinion drives the inner wall of the rain gutter that is closer to the roof space on the longitudinal axis of the vehicle. Regarding the roof of a vehicle provided with mlV?C.

Placing the electric motor at this point in front of the front of the roof opening is more advantageous than placing it elsewhere.

This means that an electric motor drive is optionally provided instead of a drive that is operated manually in most cases via a crank, and the crank is placed in the area in front of the roof opening, facing the longitudinal axis of the vehicle, for driving. This is because it is necessary to provide the electric motor 1 drive device at the above-mentioned location in order to have as many parts as possible that are the same for both drive devices.

Of course, the limited space makes it difficult to provide the electric motor and intermediate transmission.

The roof of the vehicle is covered on the inside with a ceiling, and as is often the case with modern automobiles, this ceiling has a recess in front of the roof opening that accommodates the sunshade for the driver and passengers. If you have one, the above-mentioned difficulties become particularly severe.

The object of the invention is to provide an electric motor drive of the first type, which is distinguished by the fact that it requires little space.

To solve this problem, according to the invention, an intermediate transmission is provided in the transmission housing, and the V-shaped mounting in plan view connects the motor to the transmission so that it forms a unit.
It is flanged to the housing, one side of the square is formed by an electric motor and is arranged intersecting the longitudinal axis of the vehicle, and the other side includes an intermediate transmission and has a pinion.

With this configuration, the range of the electric motor 7 drive that intersects the longitudinal axis of the vehicle is shortened and placed between the recesses accommodating the sunshade, so that the engagement points between the electric motor shaft and the intermediate transmission are necessarily One drive pinion can be provided on the longitudinal axis of the vehicle, albeit laterally to the longitudinal axis.

Further, according to the present invention, the intermediate transmission constitutes a gear train arranged substantially parallel to the downward direction of the rain gutter, and this gear train is housed within the transmission housing.

Therefore, the overall wall thickness of the intermediate transmission device can be made as thin as possible, and it is suitably housed in the space between the sunshade recesses and does not protrude significantly and interfere with the head clearance in the room. Never.

a motor shaft is connected to a shaft of an intermediate transmission, the shaft of the intermediate transmission extending outwardly through the transmission housing;
Preferably, the outer end thereof has a gear that meshes with an opening/closing gear cooperating with the opening/closing contact.

According to this proposal, a control device including an electric circuit for controlling the electric motor, that is, for shutting off the electric power of the electric motor in the terminal position, is also integrated into the unit.

The switching contacts, which are usually formed by microswitches, are fixed outside the transmission housing and are therefore easily accessible.

Particularly when the transmission device, the uzing, is disposed below the rain gutter as described above, it is advantageous to provide the control device using the dead space formed between the input side of the intermediate transmission device and the vehicle roof. .

As a result, the gear train of the intermediate transmission device can be effectively used not only for its transmission function but also as an operating means for the control device.Moreover, the control device is also housed in the put space, and the integrated installation makes the unit compact. becomes possible.

Embodiments of the present invention will be described below with reference to the drawings.

The fixed roof part 1 of the vehicle has a roof opening 2 which can be closed by means of a movable button and a lid 3vc which can be swung outwards.

The roof opening 2 is surrounded by a rain gutter 4.

The lid 3 can be moved by a drive unit 5 via one or more compression-resistant cables 6 away from the roof opening 2 and back into this opening.

The drive unit 5 has an electric motor 5a which is flanged to the transmission device 1.

A motor shaft 8 (with a d-worm 9) enters into the transmission housing 7, and this worm 9 meshes with a gearwheel 11 which is loosely mounted on @10.

A gear 12 is coupled to the shaft 10 so as to be movable in the axial direction without relative rotation, and a disk 12a is connected to the shaft 10 by a spring 13.
It is pressed against the gear 11 via the gear 11 and is connected to the gear 11 in a transmission manner by means of the slipping clutch formed thereby.

The stress of the spring 13 can be adjusted via the sleeve 15 by means of a nut 14.

The shaft 10 extends externally from the transmission housing γ and is connected to a control device which stops the electric motor 5a in the open end position and in the closed position of the lid 3.

That is, a gear 16 is provided at the extending end of the shaft 10, and this gear 16 meshes with an opening/closing gear 17.

The opening/closing gear 17 is rotatably supported on a shaft 18 formed integrally with the transmission housing T.

The opening/closing gear 1γ has two cams 19 and 20 which cooperate with contact arms 21 and 22 of microswitches 23 and 24, which power the electric motor 5a in the end and closed positions of the lid 3. cut off from

Gears 16 and 17 are configured as step feed gears, as is customary for tachometers and drive units VC.
I am trying to get the desired size of the Nansha scold.

As can be seen from FIG. 1, since the gear 16 has only two teeth with one tooth space between them, the opening/closing gear 1γ is moved by one tooth during one rotation of the gear 16.

The gear 12 has a shaft 26 fixed in the transmission housing γ.
- meshes with an intermediate gear 25 rotatably provided on the
A gear 27 meshing with this intermediate gear 25 protrudes from the transmission housing 7 and is fixed on a shaft 28 having an outer end (1) with a pinion 29, which meshes with the JjΣ contracting cable 6. .

As can be seen from FIG. 2, this pinion 29 is provided on the inner surface of the rain gutter inner wall 4a closer to the roof space [-12] toward the vehicle longitudinal axis 30-1.

As mentioned above, the intermediate transmission device is a gear train 12° 25.27 which is arranged approximately in the same manner as the button on the door surface of the rain gutter 4.
The manual power of the intermediate transmission (ill and the vehicle roof 1
The control device is located within the dead space between the tic and the control device.

A ceiling (not shown) covering the inside of the vehicle roof 1 has a recess 31 in front of the roof opening 2 for accommodating a tow 1 shade for the driver and passengers.

As can be seen from FIG. 1, a four-position driver body 5 is provided between these recesses 31.

, the drive vehicle 1>'7 body 5 has a V-shape in the plan view (Fig. 1).
Therefore, one side of V between and is formed by the electric motor 5a and is arranged to intersect with the vehicle edge/axis line 30, and the other side of the force is +'e;)j 12 + 25 27 and one drive pinion 29.

With this structure 1jk, the drive unit 5 can be accommodated even though the space between the sunshade recesses 31 is very narrow, and the drive pinion 29 can be arranged on the longitudinal axis 30 of the vehicle. Regarding the arrangement of the pinion, it is not necessary to consider a different structure than in a manually operated crank drive.
