Automatic sunroof drive in the car

The subject of the invention

The invention relates to an automatic sunshade device in the car cab, namely a retrofit version as well as a first, that is, a factory-fitted version.

BACKGROUND OF THE INVENTION

Umbrellas in the cab of motor vehicles have been known for a very long time. They are intended to provide, in particular to the driver, as well as the front seat passenger with protection from the sun when the sun is shining against the vehicle windscreen at an unfavorable angle, ie when the incident angle between the axis of the sun's rays and the ground on which the vehicle is driven is less than 90 °.

Usually two sunshades are mounted in the cab of a motor vehicle hinged on hinges that extend just above the upper edge of the windscreen; the sunshades can rotate about an angle substantially equal to the angle lying between the roof of the vehicle cabin and the windscreen and is typically more than 90 ° and less than 180 °.

When the sun visor is not in use, it is in the up position, essentially parallel to the roof of the cab, but when used by the driver or passenger, it is rotated from that initial position to a certain angle towards the lower extreme position, relative to the incident angle of the sun, the size of the person who it is used, etc .., to the lower extreme position, where the sunshade is essentially parallel to the windscreen.

State of the art and description of the technical problem

The shade manipulation is manual in all known passenger car designs.

This can be problematic especially for the driver, as he has to cut up the shade with one hand and adjust the shade to the desired position.

This is especially problematic when the driver is a disabled person with a limited movement of hands and body, which may also mean that he / she cannot cut at all.

This means that such a person who, despite having a disability, may not even be able to protect himself from the sun by a driver's license for passenger vehicles.

At the same time, with the solution of the technical problem we do not want to disable the manual movement of the sun visor, when the case is for many devices in cars (electric windows in the doors, exterior mirrors), where in the event of a failure or for some other reason, when the drive device (usually an electric motor ) does not work, manual movement is not possible at all.

The manipulation of the blinds in the cabs of some, especially larger trucks and buses is different because these vehicles have much larger windows and the blinds, at least in modern vehicles of this type, are made in the form of curtains that are rolled up above.

Description of the invention

The present invention solves the aforementioned technical problem by introducing an automatic sunroof drive in the car cab, which allows the sunroof to be manipulated by pressing a suitable button, which can be installed anywhere in the cab, depending on the needs of the driver and / or passenger.

Description of the invention

The present invention solves the present technical problem in used cars by introducing a device that enables the sun visor to be operated automatically, that is, its rotation about an axis substantially parallel to the upper edge of the car windscreen.

As shown in the figures, the device consists of an electric motor assembly and a gear unit 11 with an output axis 1 la and a mounting bracket 20.

For example, a reducer electric motor (eg: code 385, manufactured by MFA, Germany, with an outside diameter of approx. 40 mm and a length of approx. 70 mm, a nominal voltage of 12 V, a power of 6.2 W and 11000 rpm, is suitable. the diameter of the output axis lla of the gear unit is 6 mm and the output axis 1 la rotates at 15 rpm.

Figures 1, 2, 3 and 4 show the retrofit device, which represents the first embodiment of the device.

The first implementation of the device

A shaft axle 14 is mounted on the output axis 1a of said gearbox.

Said axial sleeve 14 has a larger diameter, with an intermediate sleeve 12, which has a smaller diameter at the ends and an enlarged diameter, which is gripped by a torsion sleeve 19, which is longitudinally cut and made of two parts, thereby enabling mounting on the intermediate sleeve 12, and on the said torsion sleeve 19, a shade holder 13 of the shade 25 is mounted.

The transfer of torque from the axis 1aa to the axle sleeve 14 is ensured by means of a screw 16, which can e.g. stem bolt with M5 metric thread and tapered stem end, with a strength of not less than grade 6.8 or equivalent machine element.

The axle sleeve 14 is preferably made of stainless steel or aluminum. The intermediate sleeve 12 is preferably made of a material used for clutch linings having a good friction property.

The transfer of torque from the axle sleeve 14 to the intermediate sleeve 12 is ensured by the tightness of the seat between the sleeve axle 14 and the sleeve 12, ie by friction between the outer surface of the sleeve 14 and the inner surface of the sleeve 12.

The sealing of said seating is adjustable by means of a screw 16a which is screwed into the holder of the shade holder 13 25 and presses on the outer surface of the torsion sleeve 19, which presses on the outer surface of the intermediate sleeve 12, thereby increasing the sealing tightness between the axle sleeve 14 and the intermediate sleeve 12. .

The screw 16a may be e.g. stem bolt with M5 metric thread and tapered stem end, with a strength of not less than grade 6.8 or equivalent machine element.

The conical endings of the bolt stems (16, 16a) provide for the fixing of the bushing 14 or the mounting bracket in the axial direction, similar to the bolts 23 mentioned below.

The tight seat of the axle sleeve 14 to the intermediate sleeve 12 has the function of a clutch. In the event of an overload, for example, if the sunshade 25 hits the cabin ceiling (upper extreme position) or the windscreen (lower extreme position), the axial sleeve 14 slides 12 against the intermediate sleeve and protects the device against damage.

It also allows the sun visor to be moved manually, in the event of any malfunction or when the ignition switch does not have a car start key and the electric motor is not powered.

As shown in FIGS. 1, 2, 3 and 4, the holder of the sunshade holder 13 downwards extends into the shade holder 15, which may have any cross section, preferably round or quadrangular, and into the axial opening, where the straight end of the lining of the holder 18 is inserted. and an aperture with an oblique axis, into which the curved end of the lining of the holder 18 is inserted. The axes of the two aforementioned openings are in the same plane and intersect at an angle of less than 90 ° and greater than 0 °, and their diameter is approx. 4 mm.

The shade bracket 18 is made of a 4 mm diameter round polished stainless steel bar, which is curved into a loop by loosely clamping the shade 25 at the end closer to the front door of the vehicle and adapted to the shape of the shade in the particular vehicle.

The described device is screwed by means of the mounting bracket 20 with screws 11b (not shown) to the carrier 21, which is slightly drilled along the entire length, as shown in Fig. 3, in a circular projection. A point-welded outer carrier bushing 22 is arranged in this circumference, which is in alignment with the output axis of the gear unit 1 la and is spaced approximately 10 to 100 mm, preferably 25 mm, from the front surface of said gear unit output axis. This allows the whole assembly to be mounted on a fixed sunshade bracket 24 in the car booth by means of an outer carrier sleeve 22 and two screws 23 disposed around the circumference of the outer carrier sleeve 22 at an angular distance of about 90 °. The screw 23 may be e.g.

M6 metric threaded bolt with a strength of not less than grade 6.8 or equivalent machine element. 1lb screws can be e.g. Hexagon head screws with M4 metric thread extending to the head of the screw, with a strength of not less than Class 6.8 or equivalent machine element

The device is controlled by a classic electrical switch (not shown) that can be installed anywhere in the cabin, e.g. on the steering wheel, on the inside of the door, in the area between the two seats, on the gear lever or in the center console, where the radio, air conditioning and the like are normally installed.

The switch is preferably positioned so that it can be handled easily by the disabled.

When the switch is pressed, the axis of the gear unit 1 la is rotated and, by means of the lining of the shade holder 18, the shade rotates about the axis of the fixed shade carrier 24.

If the sun visor hits the obstacles, the 12 and 14 slides slide together and the sun can be moved manually.

The front passenger's automatic sun visor is described and shown, while the driver's automatic sun visor is identical, only to be mirrored.

Another device implementation

Figure 5 shows an embodiment of a factory installation in a vehicle.

A shaft bushing 114 is mounted on the outlet axis of the lily of said gear unit 111.

Said axial sleeve 114 is substantially smaller in diameter, with an intermediate sleeve 112 having a larger diameter at the ends and an enlarged diameter embraced by a torsion sleeve 119 which is longitudinally sectioned and two-piece, thereby enabling mounting on intermediate sleeve 112.

As with the first embodiment of the device, torque transfer from the axis 11aa to the axle sleeve 114 is ensured by means of a screw 117, which can e.g. stem bolt with M5 metric thread and tapered stem end, with a strength of not less than grade 6.8 or equivalent machine element.

Ί

The axle sleeve 114 is preferably made of stainless steel or aluminum. The intermediate sleeve 112 is preferably made of a material used for clutch linings having good friction properties.

The screw 116 may be e.g. stem bolt with M5 metric thread and tapered stem end, with a strength of not less than grade 6.8 or equivalent machine element.

The tapered ends of the stems of screws 116 and 117 provide for the fixing of the bush 114 or the drive pinion 113 of the holder bracket in the axial direction, similar to the screws 130 mentioned below.

The transfer of torque from axle sleeve 114 to intermediate sleeve 112 is ensured by the tightness of the seat between the sleeve sleeve 114 and the sleeve 112, ie by friction between the outer surface of the sleeve 114 and the inner surface of the sleeve 112.

A drive gear 113 is mounted on the torsion bush 119 and secured to it by two screws 116, which are screwed into the non-gear part of the drive gear 113 and pressed against the outer surface of the torsion bush 119, which presses on the outer surface of the intermediate bush 112, thereby increasing the tightness of the seat between axial sleeve 114 and intermediate sleeve 112.

As in the first embodiment, the tight seat of the axle sleeve 114 to the intermediate sleeve 112 has a clutch function. In the event of an overload, for example, if the sun visor hits the cabin ceiling (upper extreme position) or the windscreen (lower extreme position), the axle sleeve 114 slides against the intermediate sleeve 112 and protects the device against damage.

It also allows the sun visor to be moved manually, in the event of any failure or when the ignition key does not have a key to start the car, which means that the electric motor is not powered.

The automatic sunroof drive according to the second embodiment also enables the sunroof to rotate about the substantially vertical axis of the pivot bracket 124 (Figure 5) by holding the sunshade and pulling it from the snap bearing 121 and turning it towards the glass on the vehicle door.

Figures 5, 6, 7, 8 and 9 also schematically show the sunshade 118, which is fixed to the ceiling of the vehicle at two points, on a rotating carrier 124, which also allows the sunshade to rotate about a vertical axis so that the window on the driver's door can be shaded (not shown) and in the snap bearing 121, by means of the shade axis 122, where the retainer is detachable.

To the axis of the sunshade 122 is mounted a toothed member 125, which is shown schematically in Figure 8. The toothed member 125 is arranged so that it has a toothed portion 125c that encloses approx. 200 ° of the circumference, which is in contact with the drive gear 113, and the remainder is drawn in an irregular shape that allows the element 125 to be seated and the shade 118 to be gripped by the levers 125a, 125b (Figure 8).

The element 125 is secured to the axis 122 of the shade 118 by means of two screws 130, which may be the same as the screw 16, which are screwed in the threaded hole 131 into the hub 125d of the element 125 (Figure 10). An embodiment is also possible where the element 125 and the axis 122 are made of one piece, for example, cast in plastic or aluminum.

The automatic sunroof device is mounted in the central ceiling console in the cab and attached directly to the body of the vehicle by means of the console 120 so that the entire device is above the ceiling wallpaper 123.

The device is controlled by a classic electrical switch (not shown) that can be installed anywhere in the cabin, e.g. on the steering wheel, on the inside of the door, in the area between the two seats, on the gear lever or in the center console, where the radio, air conditioning and the like are normally installed.

The switch is preferably positioned so that it can be handled easily by the disabled.

When the switch is pressed, the axis of the gear unit 11 la is rotated and, by means of the element 125, the shade rotates about the axis of the fixed shade carrier 124.

If the sun visor hits the obstructions, the bushings 112 and 114 slip between them, which protects the device against overload and also allows the sun visor to be moved manually.

The automatic sunshade device for the driver's sun visor is described and shown, while the passenger's sunshade automatic sunshade is the same except that it is mirrored.

The invention is described in two embodiments, which in no way limit it. Many modifications to the device are possible, but will be immediately clear to those skilled in the art and fully covered by the subject application. /
