Angle radar headlamp combination structure and support assembly

Abstract

The invention discloses an angle radar headlamp combination structure and a support assembly, and belongs to the technical field of automobiles, the angle radar headlamp combination structure comprises a headlamp assembly and an angle radar assembly, and the headlamp assembly comprises a headlamp shell; the angle radar assembly comprises a radar support and a front angle radar, the front angle radar is fixed to the radar support, and the radar support is fixed to the lower portion of the headlamp shell; the support assembly comprises a support tool, a centering support, a fender and the angle radar headlamp combination structure. The centering support is positioned and installed at the front end of the support tool. The left side and the right side of the support tool and the fender are installed in a positioning mode. A headlamp shell in the angle radar headlamp combined structure is respectively positioned and mounted with the center protection bracket and the fender; the positioning optimization is carried out on the structures of related parts such as the support tool, the center-keeping support and the fender, so that the requirement for improving the precision of assembling the radar support to the position of a headlamp is met.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a corner radar headlight combination structure and a bracket assembly. Background technique [0002] Millimeter-wave front angle radar is an important component of car assisted driving, and its function is mainly to detect and warn frontal obstacles. When the front angle radar is assembled on the car, there are requirements for angular deviation and horizontal angle of the installation surface. The angle between the radar axis and the longitudinal axis of the vehicle (forward direction) is Yaw±3°; pitch angle requirements: the angle between the radar axis and the ground line is Pitch± 1.5°. [0003] The prior art method installs the front corner window radar on the front bumper, such as the solution given in the invention patent 202011416701.5 "A Car Bumper Corner Radar Bracket Assembly Structure", a plastic bracket designed and assembled inside the front bumper ...

AI Technical Summary

Problems solved by technology

[0004] The problem with this method is that the front bumper is a flexible plastic part, and it has many installation points on the vehicle body, and it is easy to produce flexible deformation when it is fixed with the vehicle body. After this deformation, the front angle radar cannot meet the accuracy requirements, and the use of this method The solution is that the calibration of the front angle radar fails due to the accumulation of manufacturing deviations. When it is necessary to measure the angle deviation of the mounting surface of the angle radar bracket, the deviation of the radar mounting surface cannot be easily measured due to the shielding of the bumper skin on the outside, resulting in the three-coordinate design change. , thus limiting the problem-solving analysis of the front corner radar failure
