Claims

1. Electromotive drive arrangement for a transparent sunroof and a sun blind, arranged beneath the sunroof, of a vehicle, comprising one motor/gearing unit for actuating the sunroof and one motor/gearing unit for actuating the sun blind, wherein the motor/gearing units are fitted at the edge of the roof cut-out for the sunroof, wherein the two motor/gearing units are combined into one motor/gearing block, and wherein the stators of the two motors are housed in a common injection-moulded part, and wherein the gearings of the two motor/units are contained in respective further injection-moulded parts, which are connected to the common motor-stator injection-moulded part on either side thereof.

2. Drive arrangement according to claim 1, wherein the electric motors of the motor/gearing units are opposite one another in the motor/gearing block.

3. Drive arrangement according to claim 2, wherein the motor/gearing units are arranged in the motor/gearing block asymmetrically with respect to one another such that the stators of the two motors come to rest next to one another while extending in parallel with one another.

4. Drive arrangement according to claim 1, wherein the injection-moulded parts consist of plastics material.

5. Drive arrangement according to claim 1, wherein the injection-moulded parts consist of aluminum.

6. Drive arrangement according to claim 1, wherein output pinions of the gearings of the two motor/gearing units come to rest on the same side of the motor/gearing block in a manner protruding therefrom.

Description

(1) The disclosure will be explained in more detail below with reference to the drawings, in which:

(2) FIG. 1 shows a roof cut-out of a vehicle having a closed two-part sunroof for opening and closing the roof cut-out and having an electromotive drive arrangement according to the state of the art, which comprises a single motor/gearing unit for actuating the sunroof and a sun blind (not shown), which unit comes to rest in the front region of the roof cut-out,

(3) FIG. 2 shows an alternative first embodiment of an electromotive drive arrangement according to the state of the art compared with FIG. 1, having two motor/gearing units for separately actuating the sunroof and sun blind, wherein the two motor/gearing units come to rest together in the front region of the roof cut-out,

(4) FIG. 3 shows a variation of the arrangement from FIG. 2, having one motor/gearing unit arranged in the front region of the roof cut-out and one arranged in the rear region of the roof cut-out,

(5) FIG. 4 shows the arrangement of FIG. 1 with the sunroof open, wherein the single gearing/motor arrangement comes to rest in the rear region of the roof cut-out,

(6) FIG. 5 is a top view of an electromotive drive arrangement for a sunroof and sun blind of a vehicle, comprising two gearing/motor arrangements for separately actuating the sunroof and sun blind, wherein the two motor/gearing units are combined into one motor/gearing block,

(7) FIG. 6 is an exploded view of the arrangement from FIG. 6, and

(8) FIG. 7 is a view of the stators of the two motors of the motor/gearing block from FIGS. 5 and 6, the stators being form-fittingly contained in a common injection-moulded part.

(9) FIGS. 1 to 4 have already been explained in the introductory part in relation to the state of the art.

(10) Embodiments of the electromotive drive arrangement according to the disclosure for a transparent sunroof and a sun blind, arranged beneath the sunroof, of a vehicle will now be explained with reference to FIGS. 5 to 7.

(11) The electromotive drive arrangement in FIGS. 5 to 7 serves to drive a transparent sunroof and a sun blind, arranged beneath the sunroof, of a vehicle such as a car. This arrangement comprises one motor/gearing unit 21 for actuating the vehicle sunroof and one motor/gearing unit 22 for actuating the sun blind, wherein the motor/gearing units 21 and 22 are fitted at the edge of the roof cut-out for the sunroof. FIG. 2 shows a drive arrangement of this kind having two separate motor/gearing units 15 and 16 arranged in the front edge region of a vehicle roof cut-out. Unlike the motor/gearing units 15 and 16, which are formed and arranged separately from one another, the motor/gearing units 21 and 22 are combined to form one motor/gearing block 20.

(12) This block 20 comprises a casing consisting of three flat injection-moulded parts 23, 24 and 25, which accommodate, preferably at least in part in a form-fitting manner, the components of the motor/gearing units 21 and 22 apart from gearing output pinions 26, 27, which protrude beyond the injection-moulded parts 23, 25. As shown in FIG. 6, the three injection-moulded parts are interconnected by means of screws 28, 29, which pass through holes in flange protrusions on the opposite sides of the injection-moulded parts 23 and 25 and engage in threaded holes in the central injection-moulded part.

(13) The injection-moulded parts 23, 24 and 25 preferably consist of plastics material or alternatively of aluminium.

(14) Apart from the stators 30 and 31 and the rotors (enclosed by same, not shown) of the electric motors of the motor/gearing units 21 and 22, these units are accommodated in the two outer casing injection-moulded parts. The stators 30 and 31, on the other hand, protrude on the opposite sides of the injection-moulded parts and come to rest completely in the central casing injection-moulded part in a form-fitting manner, with their longitudinal central axes (=axes of rotation of the rotors) oriented in parallel with one another. This stator arrangement is the reason for the compact shape of the electromotive drive arrangement in the longitudinal direction of the arrangement, and, compared with the state of the art shown in FIG. 2, in which the motor/gearing units 15 and 16 are entirely separate from one another and arranged in separate casings, this shape ensures a reduced installation space of the arrangement for the benefit of the controller, which comes to rest at an axial offset from the arrangement.
