Definitions
- the invention relates to a sensor device for a motor vehicle.
- the sensor devices can include, for example, so-called ACC radar sensors, ie sensors for distance control, which can be arranged, for example, on the front of the vehicle. If the motor vehicle is a tilting vehicle, the sensor device can be arranged below a lens, for example.
- An object of an exemplary embodiment of the invention is to propose a sensor device for a motor vehicle in which alignment of the sensor device on the motor vehicle is simplified.
- a sensor device for a motor vehicle in particular for a tilting vehicle, with at least one holding frame, with at least one fixing device, through which the holding frame is fixed to at least one component of the motor vehicle relative to the
- SUBSTITUTE SHEET (RULE 26) at least one component can be fixed or fixed in place, with at least one first alignment unit for aligning the holding frame when it is fixed in a TARGET alignment, the first alignment unit comprising at least three contact points at which the holding frame touches the at least one component and/or another Component of the motor vehicle is in contact in the specified arrangement, and with at least one sensor means which can be inserted into the holding frame and fixed in place relative to the holding frame.
- the holding frame is in contact with the component of the motor vehicle and/or another component of the motor vehicle in the fixed arrangement by the first alignment unit with at least three contact points, there is no need for subsequent adjustment of the holding frame after joining.
- the orientation of the holding frame is determined sufficiently geometrically by the contact at at least three contact points. This enables the sensor device to be arranged on the motor vehicle and the alignment of the sensor device to be adjusted in a single joint assembly step.
- the holding frame can only be fixed to a single component of the motor vehicle.
- the holding frame can be fixed to a number of components of the motor vehicle.
- the first alignment unit can provide for the holding frame to rest against at least four contact points or more than four contact points. At each point of contact, the holding frame can contact the component or another part of the motor vehicle in a point-like, line-like or area-like manner.
- the motor vehicle may include a tilting vehicle.
- a tilting vehicle is understood to mean bicycles, motorcycles or motor vehicles similar to motorcycles, such as motor scooters, in particular two-, three- or four-wheeled motor scooters, scooters, tiltable trikes, quads or the like.
- the holding frame can be fitted over the fixing device without the use of tools.
- the holding frame can be clipped onto the component, for example.
- the fixing device comprises at least one projection on the holding frame, which can be fixed or is fixed in or on a receptacle of the at least one component, forming a catch from behind with respect to a first joining direction and/or if the fixing device has at least one projection which comprises at least one component which can be fixed or fixed in or on a receptacle of the holding frame, forming a catch from behind with respect to the first joining direction.
- the receptacle can have any technical design as long as it fulfills the technical function of forming a rear grip with respect to the first joining direction in the joined arrangement.
- the receptacle can be formed easily and inexpensively if it is hook-shaped or includes a recess into which the projection can be engaged and fixed to form a rear grip.
- the first alignment unit and the fixing device can comprise components that can be separated from one another and/or are separate.
- the holding frame can include a contact point on a first component of the motor vehicle and can be fixed on a second component by the fixing device. It proves to be advantageous if the first alignment unit is an element of the fixing device and/or if the first alignment unit and the fixing device comprise at least one common component.
- the holding frame is fixed at at least three points on the at least one component.
- the holding frame is also aligned at the same time as the holding frame is being joined.
- the fixing device comprises at least one screw-shaped or bolt-shaped fixing means by which the holding frame, in particular additionally, can be attached to the at least a component or another component of the motor vehicle can be fixed.
- the fixing means comprises an additional component.
- a development of the sensor device includes at least one second alignment unit, through which the sensor means lies in contact with at least three contact points on the holding frame in a joined arrangement.
- the sensor means Due to the fact that the sensor means is in contact with the holding frame at at least three contact points, the sensor means can already be aligned with respect to the holding frame during assembly.
- the second alignment unit allows the sensor means to bear against the holding frame at at least four contact points.
- the point of contact can be in the form of a point, a line or a surface.
- the alignment of the sensor means with respect to the holding frame can be further improved if the sensor means comprises a cross section transverse to a second joining direction, along which the sensor means can be arranged in the holding frame, which cross section is designed to correspond to, in particular complement, an opening in the holding frame.
- the sensor means can be arbitrarily fixed in the holding frame. Arranging the sensor means in the holding frame can be simplified if the sensor device comprises at least one coupling device, by means of which the sensor means can be fixed or fixed in place relative to the holding frame without tools.
- the coupling device can be used to fix the sensor means to the holding frame by means of a friction fit, force fit and/or form fit.
- the coupling device comprises at least one projection on the holding frame, which can be fixed or is fixed in or on a receptacle of the sensor means, forming a rear grip with respect to the second joining direction, and/or that the coupling device has at least one Includes projection on the sensor means, which is in or on a receptacle of the holding frame, forming a rear grip with respect to the second joining direction, fixed or fixed.
- the sensor means can easily be clipped into the holding frame.
- the receptacle in the holding frame can be hook-shaped, for example, or can include a recess.
- the sensor device can be designed with fewer components if the second alignment unit is an element of the coupling device and/or if the second alignment unit and the coupling device comprise at least one common component.
- the sensor means is also aligned immediately when the sensor means is joined in the holding frame with the fixing. This further facilitates assembly of the sensor device.
- At least one of the at least one component includes a diffuser or a headlight housing and/or if the sensor means comprises a radar sensor, in particular an adaptive cruise control sensor (ACC).
- ACC adaptive cruise control sensor
- the diffusing screen can comprise a diffusing screen for a headlight of the motor vehicle, in particular of the tilting vehicle.
- the sensor means can be fixed precisely aligned with respect to the lens by the aligned holding frame. As a result, the risk of undesired reflection of light in the direction of the sensor means can be reduced.
- the lens can also be arranged in a predefined arrangement on the motor vehicle. This can be done, for example, by mounting it on a substructure to which the lens can be fixed and which is connected to a supporting structure of the motor vehicle.
- the component to which the holding frame can be fixed can comprise the substructure to which the holding frame can be fixed. This further improves alignment of the holding frame and the sensor means with respect to the lens.
- the holding frame touches at least three contact points on the substructure.
- the holding frame can be in full contact with the substructure in a form-fitting manner and over a large area.
- the component may include a headlamp housing.
- the holding frame can be aligned with respect to a headlight.

- the sensor device 2 comprises a holding frame 6 and a fixing device 8, by means of which the holding frame 6 can be fixed in place on at least one component 10 of the motor vehicle 4 relative to the component 10.
- the fixing device 8 is formed at a fixing point by projections 12 on the holding frame 6 and receptacles 14 on the component 10 and at another fixing point by projections 12 on the component 10 and receptacles 14 on the holding frame 6. This fixes the holding frame 6 against removal with respect to a first joining direction 16 by means of a grip from behind.
- the fixing device 8 comprises screw-like or bolt-like fixing means 18, by means of which the holding frame 6 can also be fixed to the component 10.
- a first alignment unit 20 is provided, by means of which the holding frame 6 can be fixed in a desired alignment when it is fixed.
- the first alignment unit 20 and the fixing device 8 have the same common components. Due to the first alignment unit 20, the holding frame 6 is in contact at four contact points in the exemplary embodiments shown in the figures. This enables the holding frame 6 to be aligned at the same time as it is being joined to the component 10 .
