Description

The invention relates to an adjustment mechanism for a rearview device of a motor vehicle, in particular a Spiegeleinstellmechanismus for an exterior mirror device, comprising a base frame, and a rear view element holder for supporting a rear view element, in particular a mirror element, such as a mirror glass, wherein the rear view element holder by means of a hinge structure pivotally the base frame is connected to be pivoted about at least a first pivot axis and preferably about two pivot axes.

The base frame may be attached to a motor vehicle, for example, by firmly fixing the base frame to a housing, in particular a mirror housing, which may, for example, be pivotally connected to a support arm which may be fixedly connected to a body of a motor vehicle. The housing may then be pivoted between an extended position in which the housing extends substantially in a direction away from the body of the motor vehicle and a retracted position in which the housing extends less far outwardly and substantially in one Return direction extends more to the body of the motor vehicle along.

The adjustment mechanism can be used to adjust an angular position of a retro-viewing device, for example a mirror glass, relative to the base frame. It should be understood that the angular or rotational position of the review device may be adjusted to accommodate an operator's personal preferences. For example, the rearview element mount, which may hold a mirror glass, may be tilted substantially about a horizontal axis when a driver of the vehicle is relatively tall or short and his eyes are relatively high or relatively low relative to the mirror glass. Additionally or alternatively, the rearview element holder can be tilted about a substantially vertical axis when the driver is located relatively far forward or backward in the vehicle.

Adjustment mechanisms are known which have a so-called memory function, for example to store the personal preferences of at least one user and preferably several users. Such adjustment mechanisms are typically provided with one or more potentiometers to generate an electrical signal to indicate a pivot angle between the base frame and the rearview retainer for rotation about a corresponding pivot axis. With the aid of such an electrical signal, a controller or a so-called control unit can thus determine a current swivel angle and / or a rotational position of the rearview element holder and / or can bring the rearview element holder into a preferred rotational position, for example a rotational position which corresponds to position information which corresponds to a storage unit can be stored. However, such an adjustment mechanism, which has a so-called memory function, is relatively expensive, for example, at least in part because of the potentiometers, which are often designed as dedicated components that are specially designed and manufactured for such an adjustment mechanism.

For example, an adjusting mechanism is known which has a dedicated potentiometer which includes a support member securely fixed to the base frame and a resistance path securely fixed to the support member. The dedicated potentiometer of this known adjustment mechanism further comprises an input gear rotationally coupled to the support member and a wiper connected by a sliding coupling to the input gear having a sliding moment greater than the moment of friction between the resistance path and the Grinder is. In this dedicated potentiometer, the support part of the potentiometer is equipped with a stop and the wiper is equipped with a corresponding counter-stop. During installation of the dedicated potentiometer, the input gear equipped with the wiper is mounted together with the support member equipped with the resistance track. The rotational position of the grinder relative to the resistance path is then not known. To calibrate the potentiometer, the input gear is subsequently rotated relative to the support member to such an extent that it is certain that the abutment and the counter-abutment are engaged, for example, by rotating the input gear at least 360 °. Since the slider is then in a known rotational position, in particular an end position, it is known after a stop of the rotation of the input gear that the current rotational position of the input gear corresponds to the known rotational position of the grinder. In this way, the dedicated potentiometer is calibrated.

Although the calibration of the known dedicated potentiometer is relatively simple and convenient, the use of a dedicated potentiometer is not as cost effective as using a more standard potentiometer, which is, for example, a purchased component or standard part.

Nevertheless, even with the use of a relatively standard potentiometer, especially a standard purchased component, an adjustment mechanism that has a so-called memory function is still relatively expensive compared to a similar adjustment mechanism that has no so-called memory function and therefore free from any potentiometers.

In order to provide both relatively inexpensive adjustment mechanisms for cheap automobiles or small cars, as well as relatively sophisticated adjustment mechanisms for premium motor vehicles, such as relatively expensive luxury cars, a manufacturer of adjustment mechanisms typically manufactures and stores and markets various adjustment mechanisms. However, it may, for example, be a disadvantage from a logistical point of view if there are different production lines and / or different parts or products are stored.

It is an object of the present invention to provide an alternative adjustment mechanism for a rearview device of a motor vehicle. In particular, it may be an object of the disclosure to provide an adjustment mechanism in which at least one disadvantage of a known adjustment mechanism is eliminated. In particular, the disclosure may be directed to providing an adjustment mechanism having one or more potentiometers for generating electrical signals indicative of pivotal angles between the base frame and the rearview retainer, which adjustment mechanism may eliminate the disadvantage of having different production lines and / or storage Parts or products are needed when a manufacturer wants to provide both relatively sophisticated adjustment mechanisms that have a so-called memory function and relatively cheap adjustment mechanisms that do not have such a so-called memory function. Alternatively or additionally, the disclosure may be directed to providing an adjustment mechanism having one or more potentiometers for generating electrical signals indicative of pivotal angles between the base frame and the rearview retainer, wherein no dedicated potentiometers are necessary, and wherein the adjustment mechanism is preferably in a relative position simple way, still can be calibrated. Alternatively, or additionally, it may be an object of the disclosure to provide an alternative method of providing an adjustment mechanism for a rearview device with a potentiometer, preferably in a manner in which the adjustment mechanism can be calibrated, more preferably in which the adjustment mechanism is relatively easily calibrated can be.

To this end, the disclosure provides an adjustment mechanism for a rearview device of a motor vehicle, preferably a mirror adjustment mechanism for an exterior mirror device. The adjustment mechanism includes a base frame that may be secured to a motor vehicle, for example by securing the base frame firmly to a mirror housing, which may, for example, be pivotally connected to a support arm which may be fixedly connected to a body of the motor vehicle. The adjustment mechanism also comprises a rearview element holder for holding a rearview element, in particular a mirror element, wherein the rearview element holder is pivotally connected to the base frame by means of a hinge construction in order to be pivoted about at least a first pivot axis. It should be understood that the adjustment mechanism may include one or more drive motors for driving rotation of the rearview element support relative to the base frame about a respective pivot axis. For example, two drive motors may be provided, wherein a second pivot axis may preferably extend substantially transverse to a first pivot axis. For example, one of the two pivot axes may allow adjustment of a rearview element about a substantially horizontal axis and the other pivot axis allow adjustment about a substantially vertical axis. It should be noted that the base frame is equipped with a plurality of electrical conductors, which may serve for example for feeding and / or controlling one or more drive motors and / or for electrically connecting one or more potentiometers to a controller or a so-called control unit. The corresponding electrical conductor has a first terminal for electrical connection to a terminal of an electrical or electronic component of the adjustment mechanism, for example a drive motor or potentiometer, and a second terminal for electrical connection to a power source and / or a controller disposed outside of the adjustment mechanism are. Furthermore, the base frame comprises a first part, which is pivotally connected to the rearview element holder, and a second part, which forms a cover for at least partially covering one or more openings in the first part of the base frame. Furthermore, the electrical conductors are integrated or assimilated in the second part of the base frame. Advantageously, the second part of the base frame may be or include an insert injection molded part in which the electrical conductors are partially made of plastic material which is substantially injection molded around the electrical conductors.

By providing a base frame comprising at least a first part pivotally connected to a rearview element holder and a cover forming a second part in which the electrical conductors are assimilated or integrated, preferably by providing a second part which is insert molded Part or part comprising electrical conductors partially enclosed in plastic material may be a modular base frame. In embodiments, the modular base frame may comprise a cover which forms a second part of the base frame, which is equipped with one or more, preferably two, potentiometers, so as to allow the formation of an adjustment device which has a so-called memory function, while In alternative embodiments, the modular base frame may include an alternative, preferably relatively simple and / or relatively inexpensive, cover that forms the second part of the base frame that is free of potentiometers so as to provide a relatively simple and / or relatively inexpensive adjustment device, possibly has no so-called memory function.

For example, a manufacturer of adjustment mechanisms may manufacture a first part of a base frame, which in preferred embodiments may be pre-assembled to form a subassembly with at least one rearview retainer for supporting a rearview element, wherein the first part of the base frame and / or the subassembly has one or more openings so as to provide access to at least one or more splined parts or gears for cooperation with one or more of the one or more input gears rotationally coupled to a wiper or resistive path of a potentiometer, preferably the potentiometer can be firmly attached to the cover, which forms the second part of the base frame. By attaching a second part of a base frame, which is equipped with one or more potentiometers, to the first part of the base frame or to the subassembly, for example, in a manner in which an input gear connected to the corresponding potentiometer with a toothed part or a gear is engaged to pivot the input gear in response to that the rearview element holder is rotated relative to the base frame about the first pivot axis, an adjustment mechanism can be formed with a memory function. On the other hand, by attaching a second part of a base frame which is not equipped with a potentiometer, a relatively inexpensive and / or relatively simple adjustment mechanism without a memory function can be formed on the first part of the base frame or on the subassembly, the second one Part of the base frame then covers the one or more openings that were initially open.

In fact, the adjustment mechanism of the present disclosure may allow already assembled base frame parts and / or already assembled adjustment mechanisms to be retrofitted by removing a particular attached second part of a base frame and replacing it with an alternative second part of another type of base frame. For example, an adjustment mechanism that has no memory function can be converted to an adjustment mechanism that has a memory function, or vice versa. Therefore, a supply of adjustment mechanisms can be changed to respond to a particular demand.

In embodiments, the cover forming the second part of the base frame and / or forming the first part of the base frame comprises connectors, preferably snap means, for securely attaching the cover forming the second part of the base frame to the first part of the base frame. Advantageously, the connectors may be releasable connectors, for example, to allow retrofitting and / or repair of the adjustment mechanism.

By insert-molding the electrical conductors into the cover forming the second part of the base frame, the second part can be made in a relatively simple and / or relatively reliable manner and / or can be relatively durable.

Advantageously, one or more, preferably all, electrical conductors may be formed from stamped parts. The stamped parts may be parts that are at least partially made by die cutting or so-called stamping, and / or may be at least partially formed by bending.

In embodiments, the conductors may first be insert molded into a cover forming the second part of the base frame. Subsequently, one or more potentiometers may be attached to the second part, for example by electrical connection, for example by soldering, of their respective terminals to corresponding terminals of the conductors.

It should be noted that in the case where the second part of the base frame forming cover is not one or more Potentiometers is equipped, the second part forming cover can still have conductors for connection to one or more potentiometers. As a result, the same integrated part, particularly one that is an insert molded part, can be used for relatively sophisticated and relatively inexpensive adjustment mechanisms. However, the cover forming second parts of the base frame for adjustment mechanisms without memory function can alternatively be formed as integrated parts, in particular insert-molded parts which have no conductors for potentiometers, the integrated parts then, for example, only conductors for connection to one or more Drive motors have.

It will be appreciated that the adjustment mechanisms in this manner may include at least one potentiometer for generating an electrical signal indicative of a pivot angle between the base frame and the rearview retainer, in particular one indicative of a pivot angle with respect to rotation about a first pivot axis.

In advantageous embodiments, the potentiometer may comprise a support member securely fixed to the base frame or the rearview element mount, an input shaft pivotally connected to the support part of the potentiometer, a resistance track or a wiper. Either the resistance track or the slider is then securely attached to the support part of the potentiometer, and the other of the resistance track and the slider is then securely fixed to the input shaft. Further, the adjustment mechanism may then include an input gear fixed to, for example, rotationally fixed to the input shaft of the potentiometer, the adjustment mechanism being arranged to pivot the input gear in response to the rearview element support being rotated relative to the base frame about the first pivot axis For example, if the input gear is not rotationally symmetric, for example, the input gear does not look the same after a certain turn unless it is a 360 ° rotation about the center axis of the input shaft, then it is fully rotated back to its initial position. It is understood that even if the input gear is not rotationally symmetric, this does not mean that the input gear can not be mirror-symmetrical. The input gear can therefore be mirror-symmetrical.

As a result of the non-rotationally symmetrical input gear, by observing the rotational position of the asymmetrical input gear, the rotational position of the grinder or the resistance track, which are indirectly rotationally coupled to the input gear, can be observed before mounting the adjustment mechanism. Therefore, before securely attaching the support member of the potentiometer to the first subassembly, one can easily bring the potentiometer into a predetermined rotational position, for example a central position, from which it can then be rotated equally clockwise as well as counterclockwise, and / or is it easy to check if the potentiometer is placed in a predetermined rotational position. As a result, the disclosure therefore provides an adjustment mechanism for a rearview device of a motor vehicle that can be made relatively simply, relatively conveniently, and / or relatively inexpensively, for example, without having to calibrate the potentiometer after securely attaching the potentiometer to the base frame the rear view device holder is necessary.

The disclosure also provides a method including a step of providing a first subassembly having a rearview retainer for supporting a rearview element, the rearview retainer being pivotally connected to a first portion of a base frame by a hinge construction to permit the rearview retainer to relative to the first part of the base frame at least about a first pivot axis, the method further comprising a step of providing a second subassembly having an input gear fixed to an input shaft of a potentiometer in such a manner that a predetermined one Rotary position of the input gear corresponds to a predetermined rotational position of the input shaft of the potentiometer, wherein the potentiometer has a support member and wherein the input shaft is pivotally connected to the support member, wherein the potentiometer fer ner has a resistance path and a slider, wherein either the resistance path or the slider, that is, the resistance of the grinder, securely attached to the support part of the potentiometer, and the other one of the resistance path and the grinder is securely attached to the input shaft, said A method further comprises a step of retaining the rearview element holder in a predetermined rotational position relative to the first position of the base frame while the support member of the potentiometer of the second subassembly is fixedly secured, wherein the second subassembly then has the input gear disposed substantially in a predetermined rotational position corresponds to the predetermined rotational position in which the rearview element holder with respect to the first part of the base frame on the first part of Base frame or on the rear view element holder is held.

By securely attaching the carrier part of the potentiometer to the first subassembly, while on the other side the first part and the base frame of the first subassembly are at a predetermined angular position to each other, and on the other side the wiper and the resistance path, one of which the potentiometer is rotatably coupled to the support member of the potentiometer are also in a predetermined angular position relative to each other, the potentiometer can be attached to the first subassembly in such a way that a predetermined position of the first subassembly corresponds to a known position of the potentiometer, d. H. a known mutual position of its grinder and its resistance corresponds. As a result, an automotive rear-view adjustment mechanism may be provided with a potentiometer for generating an electrical signal for indicating a pivot angle between its base frame and its rearview retainer without calibrating the potentiometer after securely attaching the potentiometer to the base frame or on the rear view element holder is necessary. Moreover, this method does not require the use of a dedicated potentiometer having a resistive track or slider coupled to a rotatable part of the potentiometer, for example its input gear, by means of a sliding coupling. Therefore, the present method can be relatively simple, relatively convenient and / or relatively inexpensive.

It should be understood that the first portion of the base frame or the rearview retainer may include a splined portion or gear for cooperation with the input gear of the second subassembly to pivot the input gear in response to the rearview element mount being relative to the base frame about the first pivot axis is turned. Advantageously, the input gear is engaged with the toothed part or gear during the step of attaching the support part of the potentiometer to the first part of the base frame or to the rearview element holder. Therefore, after securely attaching the support member of the potentiometer to the first part of the base frame or to the backsheet support, a mechanical coupling between the potentiometer and the first subassembly can be made. From this moment then corresponds to the mutual angular position of corresponding parts of the potentiometer, d. H. of the wiper and resistance path of the potentiometer, the mutual angular position of the corresponding parts of the first subassembly, d. H. its rear view element holder and its first part of the base frame. Thereafter, after the attachment of the potentiometer with respect to the first subassembly, it is then possible to stop holding the rearview element holder in its predetermined rotational position with respect to the first part of the base frame.

In preferred embodiments, the input gear may be formed as a non-rotationally symmetrical input gear. In even more preferred embodiments, a deviation that causes the input gear to be non-rotationally symmetric may be visible after the non-rotationally symmetrical input gear is mounted on the input shaft of the potentiometer such that a predetermined rotational position of the non-rotationally symmetrical input gear is at a predetermined rotational position corresponds to the input shaft of the potentiometer. In this way, it is relatively easy to determine or check that the non-rotationally symmetrical input gear and therefore the rotationally coupled input shaft of the potentiometer and thus rotatably coupled grinder or the rotationally coupled coupled resistance path is arranged in the correct rotational position before and / or during the Carrier part of the potentiometer is attached to the first part of the base frame or on the rearview element holder, while the first part of the base frame is held in a predetermined rotational position with respect to the Rückschauelementhalterung, wherein the predetermined rotational position corresponds to the rotational position of the non-rotationally symmetrical input gear, and therefore the rotational position of the grinder or corresponds to the resistance path, which is rotationally coupled via the input shaft of the potentiometer with the non-rotationally symmetrical input gear.
