Problems solved by technology

But in this device, there is still the problem that for the interference-free and low-noise operation of the device, the swing axis of the environment detection unit, the swing axis of the protection element and the articulation of the connection joint between the environment detection unit and the protection element must be articulated The axes are precisely aligned with each other, but due to tolerances in practice this cannot always be achieved

Embodiment Construction

[0027] The device shown in the figures has an environment detection unit 10 which, in the present embodiment, includes a reversing camera 12 for a motor vehicle.

[0028] The environment detection unit 10 is supported rotatably about a first rotation axis 14 and a second rotation axis 16 spaced therefrom. Here, the first axis of rotation 14 is displaceably guided along a curved link not shown, while the second axis of rotation 16 is arranged at the first end of a rocker arm 18 , which is supported rotatably about a third axis of rotation 20 . the second end of the arm.

[0029] The environment detection unit 10 can enter the use position for image acquisition by moving out ( image 3 ), and by driving into the motion into the rest position ( figure 1 ). The movement out and in of the environment detection unit 10 is induced by a drive unit comprising a toothed rack 22 articulated to the environment detection unit 10 . In the present embodiment, the rack 22 acts on the env...

Abstract

The invention relates to a device for a motor vehicle having a protective element which can be pivoted from a closed position into an open position, with an environment detection unit which can be moved into an active position for image detection by an extension movement and into a resting position by a retraction movement, in which the environment detection unit is arranged to be externally inaccessible behind the protective element located in the closed position, and having a drive unit acting on the environment detection unit for moving the environment detection unit, the environment detection unit having an end face facing the protective element and two has adjoining side surfaces and wherein a pressing element for pressing on the protective element during the extension of the environment detection unit and a separate closing element for closing the protective element during retraction of the environment detection unit are formed on at least one of the side surfaces.

Description

technical field [0001] The present invention relates to a device for a motor vehicle comprising: a protective element deflectable from a closed position into an open position; into a rest position, wherein in the rest position the environment detection unit is arranged inaccessibly from the outside behind the protective element in the closed position; and a drive unit which acts on the environment detection unit for moving the environment detection unit, wherein the environment detection unit It has an end face facing the protective element and two side faces immediately adjacent to it. Background technique [0002] In known devices of the type mentioned at the outset, the protective element is held in the closed position by a spring element and is pushed away by the end face of the extended surroundings detection unit. However, due to the spring-back force of the spring element which weakens over time and / or due to vibrations which occur during driving operation, problems ...
