Such a carrier device is known from DE 10 2008 050 320 A1 known. The carrier device can be fastened to a pane, in particular a windshield, of a motor vehicle and comprises a carrier plate which can be fastened to the pane. The support plate has at least one support element on which at least one camera, a sensor or the like can be fastened in a fastening region of the support plate. The carrier device further comprises a spring arrangement with at least one spring element, by means of which the camera, the sensor or the like can be acted upon by a force against the carrier element.

It has been found that this carrier device is in need of improvement in terms of compensation of tolerances.

It is therefore an object of the present invention to provide a carrier device of the type mentioned in the introduction as well as a fastening arrangement of a camera, a sensor or the like on a carrier device, which have an improved tolerance compensation.

This object is achieved by a carrier device for attachment to a disc having the features of patent claim 1 and by a fastening arrangement of a camera, a sensor or the like on a carrier device having the features of patent claim 9. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.

Such a carrier device for attachment to a pane, in particular a windshield, of a motor vehicle, comprises a carrier plate fastened to the pane. The support plate has at least one support element on which at least one camera, a sensor or the like can be fastened in a fastening region of the support plate. The carrier device comprises a spring arrangement with at least one spring element, by means of which the camera, the sensor or the like can be acted upon by a force against the carrier element.

According to the invention, the support element has a receptacle in which a holding element of the camera, the sensor or the like is at least partially receivable. In the recording, the spring element is arranged at least partially. By means of the arranged in the receptacle spring element, the holding element of the camera, the sensor or the like can be acted upon directly by the force. As a result of the direct loading of the retaining element by means of the spring element, the tolerance chain of the attached to the support plate camera, the sensor or the like can be kept particularly low. Thus, the camera, the sensor or the like can be defined and attached without play to the carrier plate, without resulting in unwanted noise, for example as a result of movements of the camera, the sensor or the like relative to the carrier plate. In the following, for the sake of better readability, reference is merely made to the camera. It is understood that this also means the sensor or the like.

The advantageous attachment and application of force to the camera on the support plate is also the function of the camera to good, since for example in the camera, an image offset due to bending moments can be avoided or kept in very small limits.

The advantageous and caused by the spring element tolerance compensation is particularly advantageous for carrying when the support plate and / or the holding element is at least substantially formed of a plastic or are. By means of the direct application of force to the holding element by the spring element, it is possible in particular to efficiently compensate for production-related tolerances of the carrier plate and / or the camera. Furthermore, the weight of the carrier device and the camera can thus be kept low. The holding element is formed for example by a housing of the camera and in particular integrally formed with the housing.

In an advantageous embodiment of the invention, at least a second support element of the support plate is provided, on which the camera can be fastened in the fastening region and which has a second receptacle in which a second retaining element of the camera can be received at least in some areas. In this case, a second spring element of the spring arrangement is at least partially disposed in the second receptacle, by means of which the second holding element is directly acted upon by a second force against the second support member. By providing the second support element with the second spring element, a particularly firm and defined attachment of the camera to the support plate is made possible. In addition, a relative movements of the camera to the support plate and a resulting rattle can be safely avoided.

In a further advantageous embodiment, the holding elements are arranged with the spring elements in spaced-apart, lateral edge regions of the fastening region. As a result, loads acting on the camera, such as forces and moments, in particular bending moments, can be avoided or at least minimized, so that unwanted noise due to relative movements of the camera to the carrier plate can be avoided. Furthermore, this is the functional performance of the camera to good, especially since an image shift in the camera designed as a stereo camera can be avoided. Another advantage is that the spring elements can be made particularly small in size and with a low cost of materials, so that the carrier device according to the invention has a very low weight. This also comes at a low cost of the carrier device to good. It can also be kept low in the preparation of the spring elements a waste.

In a further advantageous embodiment of the invention, the spring arrangement comprises at least a third spring element, which is arranged on the support plate between the first and the second spring element and by means of which the camera with a third force against the support elements and / or against at least one further support member of the support device can be acted upon. Thus, an advantageous application of force to the camera is realized at at least three spaced-apart locations by the three spaced-apart spring elements. The camera is thus defined and held firmly on the support plate.

In a further advantageous embodiment, the force or the forces point away from the carrier plate. This allows a simple, time-consuming and cost-effective installation of the camera.

A particularly firm and defined support of the camera on the support plate is realized in particular when the spring arrangement comprises at least one further spring element by means of which the camera can be acted upon by a further force pointing at least substantially parallel to the support plate against the support element or the support elements. In this way, the camera can be acted upon with forces in at least two different directions, which is accompanied by a particularly advantageous tolerance compensation.

Preferably, a respective Hintergreifung can be formed between the support member and the corresponding support member or between the support members and the respective corresponding support elements, whereby the camera can be latched to the support element or with the support elements. The camera can thus be mounted in a simple and therefore time and cost-effective manner to the support plate by simply latching. Here, for example, the first spring element, the second spring element and the third spring element are compressed, that is stretched by the corresponding holding elements of the camera are arranged in the first receptacle of the first support member and in the second receptacle of the second support member. The third spring element is pressed together, for example via the housing of the camera.

In the course of assembly then the other spring element is pressed together, that is taut, which then presses the camera at least substantially parallel to the support plate in the recordings and in the Hintergreifungen. The first spring element, the second spring element and the third spring element push the camera away from the carrier plate, in particular at least substantially perpendicularly to the carrier plate away therefrom, against the carrier elements or against corresponding walls of the carrier elements which at least partially bound the receptacles. As a result, the camera, the sensor or the like is held securely and at least substantially free from play on the carrier plate.

In a particularly advantageous embodiment of the invention, the spring element or the spring elements are inserted into the corresponding receptacle in at least one insertion direction. In other words, the receptacle is accessible in at least one direction, so that thereby the corresponding spring element can be arranged in a simple and thus time-consuming and cost-effective manner in the receptacle and inserted into it. As a result, an automatic assembly of the carrier plate with the spring elements, for example by means of a robot, is possible in particular, which leads to a cost-effective production of the carrier device.

For holding the spring elements in the receptacles on the support plate, the spring elements are preferably locked to the support plate. This allows a fast and inexpensive arrangement of the spring elements in the recordings.

The invention also includes a fastening arrangement of a camera, a sensor or the like on a carrier device, in particular on a carrier device according to the invention. About the support device, the camera on a disc, in particular a windshield, a motor vehicle can be fastened. The carrier device comprises a carrier plate which can be fastened to the disc and has at least one carrier element. On the support element, the camera is in one Attached mounting area of the support plate. The camera is acted upon by a force against the support element by means of at least one spring element of a spring arrangement of the support device.

According to the invention it is provided that the support element has a receptacle in which a holding element of the camera is at least partially received and in which the spring element is arranged at least partially. By means of the spring element, the holding element is acted upon directly by the force. Advantageous embodiments of the support device according to the invention are to be regarded as advantageous embodiments of the fastening arrangement according to the invention and vice versa.

The mounting arrangement according to the invention has only a very small tolerance chain, since the holding element of the camera, which is designed for example as a fastening bolt or the like rod member, acts directly with the spring element together and is thus acted upon directly by the force. Thus, undesired relative movements of the holding element can be avoided to the support plate. Thus, unwanted noise is avoided. Another advantage of the direct application of force to the retaining element is that thereby bending moments acting on the camera can be avoided or at least kept very small. This is the function of the camera to good. If the camera is designed, for example, as a stereo camera, an undesired image offset can thereby be avoided.
