Background

Due to the changing road environment and the requirements of vehicle drivers for the safety of vehicles, more and more vehicle manufacturers are equipping their own vehicles with parking radars. Parking radars are safety aids for backing or parking vehicles and are generally classified into front radars and rear radars.

The front radar is designed and developed based on the principle that bats fly at high speed in the dark without colliding with any obstacles. The front radar is mainly used for front parking assistance, is a safety auxiliary device for vehicles during parking, and mainly comprises an ultrasonic sensor, a controller, an alarm and the like. The ultrasonic sensor of the front radar is mounted on the front bumper, and the ultrasonic sensor radiates at an angle of about 45 degrees to search for a target in up, down, left, and right directions. The warning indicator can prompt the distance between the vehicle and surrounding obstacles through sound, so that the safety of parking the vehicle is improved.

The rear radar is arranged on a rear bumper and mainly comprises an ultrasonic sensor, a controller, an alarm and the like. When the reverse gear is switched, the rear radar automatically starts to work. When the ultrasonic sensor detects that an object exists behind the vehicle, the warning device gives out a warning. The warning device can give out different warning sounds to remind a driver along with the change of the distance between the rear bumper of the vehicle and an object.

In vehicles currently sold and used, which are mounted with parking radars, the parking radars mounted on the front and rear bumpers are generally clearly seen, and for example, the parking radars exhibit a round convex configuration on the front and rear bumpers.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples, which should not be construed as limiting the invention.

Referring first to fig. 1 to 5, a radar mechanism for a vehicle according to an embodiment of the present invention mainly includes a radar device 10, a first panel 30, and a second panel 50.

The radar device 10 is used to detect an object existing on the front side in the vehicle longitudinal direction and/or the rear side in the vehicle longitudinal direction, for example, to detect another vehicle existing on the front side or the rear side of the vehicle or a wall surface of a building when the vehicle is parked. The radar device 10 has a transmitting unit (not shown) and a receiving unit (not shown), the radar waves transmitted by the transmitting unit are transmitted by an object after reaching the object, the receiving unit receives the transmitted radar waves and calculates the distance between the vehicle and the object based on the received radar waves, and then prompts are given to the driver in different forms according to the distance between the vehicle and the object. For example, when the vehicle is relatively far from the object, the prompt is made by a gentle buzzing prompt tone, and when the vehicle is relatively close to the object, the prompt is made by a sharp buzzing prompt tone.

The first panel 30 may be located on the front side and/or the rear side in the vehicle front-rear direction of the radar device 10, and although fig. 1 exemplarily shows that the first panel 30 is located on the front side in the vehicle front-rear direction of the radar device 10, the description made with respect to the case where the first panel 30 is located on the front side in the vehicle front-rear direction of the radar device 10 is equally applicable to the case where the first panel 30 is located on the rear side in the vehicle front-rear direction of the radar device 10.

As can be seen from fig. 1, the first panel 30 and the radar device 10 have a gap P therebetween, which may be defined as a distance between a surface of the first panel 30 facing the radar device 10 and a surface of the radar device 10 facing the first panel 30. Due to the presence of the gap P, the radar device 10 is mounted in a built-in manner, rather than being exposed outside the first panel 30, such a configuration provides protection for the radar device 10, significantly reducing the risk of damage to the radar device 10 due to physical contact with other objects.

Referring now to fig. 2, the first panel 30 is provided with apertures 31, and for example, in order to cover a larger detection range, four apertures 31 are provided on the first panel 30 in the vehicle width direction of the first panel 30, one radar device 10 being provided for each aperture 31. The aperture 31 penetrates the first panel 30 and corresponds in position to the radar device 10, that is, at least a part of the radar device 10 can be seen through the aperture 31 when the first panel 30 is viewed in the vehicle front-rear direction. The aperture 31, which is circular in shape in projection in the vehicle front-rear direction, is exemplarily shown in fig. 2. Of course, the opening 31 may be polygonal such as rectangular, square, etc., or may be elliptical. Such shaped apertures 31 are regular in shape and easy to machine, for example by stamping the first panel 30 to form the apertures 31.

In the preferred embodiment of the present invention, the size of the aperture 31 may be set so that the projection of the radar device 10 in the vehicle front-rear direction is located within the range of the projection of the aperture 31 in the vehicle front-rear direction, and more preferably, the projection of the radar device 10 in the vehicle front-rear direction is located in the central region of the projection of the aperture 31 in the vehicle front-rear direction. Referring to fig. 1, in such a preferred embodiment, radar waves can smoothly and sufficiently enter and exit the first panel 30 via the aperture 31, thereby facilitating detection (the transmitting unit of the radar device 10 sends out radar waves to detect objects existing on the front and/or rear side of the vehicle) and ranging (the receiving unit of the radar device 10 receives radar waves reflected from the objects and calculates the distance between the vehicle and the objects) of the radar device 10.

It is obviously undesirable to expose the aperture 31 from the viewpoint of the integrity of the structure and the protection of the radar apparatus 10, and therefore, the radar mechanism for a vehicle of the present invention employs the second panel 50 to close the aperture 31. As shown in fig. 3, the second panel 50 blocks the orifice 31 from the front side of the first panel 30 in the vehicle front-rear direction (for example, in the case where the first panel 30 is a front bumper panel). However, for the case where the first panel 30 is located on the vehicle front-rear direction rear side of the radar device 10 (for example, the case where the first panel 30 is a rear bumper panel), the second panel 50 blocks the aperture 31 from the first panel 30 on the vehicle front-rear direction rear side. As shown in fig. 4, the second panel 50 may be sealed at both the front and rear sides of the orifice 31 in the vehicle longitudinal direction, thereby contributing to securing the strength of the first panel 30 after being bonded to the second panel 50.

Specifically, as shown in fig. 5, the second panel 50 is joined to the first panel 30, for example, by bonding the two together using an adhesive or by welding the two together. In order to make the first panel 30 and the second panel 50 more integral, a first coating layer is coated on the first panel 30, and a second coating layer having the same color as the first coating layer is coated on the second panel 50, and the first coating layer and the second coating layer are also joined as a whole. The first coating layer may be sprayed using a coating material containing a metal substance (for example, a metallic paint to which aluminum powder or copper powder is added) in consideration of protecting the surface of the first panel from corrosion from the outside. The spraying of the second coating may be performed using a non-metallic coating (e.g., a ceramic coating, etc.) in consideration of the passage of radar waves through the orifice 31.

The utility model provides an above-mentioned radar mechanism for vehicle can be applied to the utility model provides an in the vehicle, the utility model provides a vehicle can be with electric drive's vehicle or can be with the vehicle that the internal-combustion engine is the power supply. The utility model discloses a radar mechanism for vehicle can set up the utility model discloses a front bumper and/or rear bumper department of vehicle, specifically, can set up at front bumper panel and/or rear bumper panel inboard.
