Technical Field
The utility model relates to an automobile-manufacturing field especially relates to an automobile-used preceding crashproof millimeter wave radar structure.
Background
The main functions of the front anti-collision millimeter wave radar in the automobile are to cooperate with ACC (adaptive cruise) and AEB (automatic emergency braking) in an ADAS (adaptive cruise control) intelligent driving auxiliary system. Because the automobile has more uncontrollable factors to cause a plurality of traffic accidents which should not happen in the driving process, for example, under the condition that two automobiles are close to each other, the front automobile suddenly decelerates or brakes, and the rear-end collision accident is easily caused by the interval time of the reaction capacity of people. At the moment, a 77GHz millimeter wave radar is needed in the middle of a front bumper of the vehicle to detect the relative speed and the relative distance between the front vehicle and the own vehicle, and the potential danger information is responded to a driver in advance to give an early warning before an accident occurs, so that the occurrence rate of rear-end accidents is effectively reduced. If the system detects that the two vehicles are inevitably collided, an instruction is sent to automatically and emergently brake, so that the severity of the accident is reduced. The millimeter wave radar placed at the center of the front bumper is generally referred to as a 77GHz front collision avoidance millimeter wave radar. At present, the angle of a pre-77 GHz anti-collision radar which is carried in the automobile market is fixed, and the pre-77 GHz anti-collision radar is only suitable for a specific automobile type generally and cannot share other automobile types. Or some motorcycle types's radar fixed knot constructs angle of adjustment, but structural style is single, and stability has the risk.
For example, a "mounting structure of a radar for a vehicle" disclosed in chinese patent literature, publication No. CN208006899U, includes a front impact beam and a front grille, the front impact beam being installed behind the front grille; the radar mounting bracket is connected with the front anti-collision beam; the radar is installed in the radar installing support. Be equipped with the draw-in groove on the radar support, the radar passes through joint portion and draw-in groove fixed connection, its weak point is, radar and radar support fixed connection, relative position is unadjustable between the two, can be directly die the angular position restriction of radar, can't finely tune again, this position that has just led to the radar to match when the loading needs very high location and size precision, and this has increased the requirement to production and processing technology undoubtedly, and because the location structure of special design can not generally be used on a plurality of motorcycle types, and then increased follow-up motorcycle type and to research and develop again. These all add significant cost to development and manufacturing.
Disclosure of Invention
The utility model relates to an overcome prior art's unable regulation of radar angle, to assembling accuracy requirement height, the structure can not be dismantled in a flexible way etc. and lead to research and development and manufacturing cost too high problem, provides an automobile-used preceding crashproof millimeter wave radar structure, and radar angle is adjustable, and the structure can be dismantled in a flexible way, and applicable motorcycle type scope is wide, and is bigger to assembly error's containment, has also increased self compatibility, and reduce cost drops into by a wide margin.
