CN-121989852-A - Radar support

Abstract

The invention provides a radar bracket which is arranged on a bumper of a vehicle in a radar-retaining state, and can inhibit or prevent sagging caused by the self weight of the bumper. A convex portion is provided at a lower portion of the radar stand so as to be opposed to an upper surface of at least 1 of vehicle body parts including the lamp in the vehicle. In this structure, assuming that the bumper to which the radar bracket is attached sags with time due to its own weight, the convex portion of the radar bracket immediately abuts against the upper surface of the lamp, so that the radar bracket is supported by the vehicle body member including the lamp.

Description

Radar support Technical Field The invention relates to a radar support. Background For example, patent document 1 describes that "the radar device 20 for detecting an obstacle around a vehicle is provided on the inner surface side of the rear bumper 70 of the vehicle via the mount 25" or "the radio wave absorbing member 60 is attached to the bracket 30" based on the mechanical connection between the main body engaging portion 46 and the engaging portion 66. Patent document 1 WO2022/138059 Disclosure of Invention In patent document 1, there is a concern that "if the rear bumper 70 sags due to its own weight due to aged deterioration," the detection range of the radar device 20 changes, resulting in erroneous detection. In view of such circumstances, an object of the present invention is to provide a radar mount that is mounted to a bumper of a vehicle while maintaining a radar, and that can suppress or prevent sagging caused by the self weight of the bumper. The present invention is characterized by a radar mount that is attached to an inner surface of a bumper of a vehicle in a radar-retaining state, and that is provided with a protruding portion at a lower portion thereof so as to face an upper surface of at least 1 of vehicle body members including a lamp in the vehicle. According to this configuration, even if the bumper to which the radar bracket is attached sags due to its own weight, the convex portion of the radar bracket is immediately brought into contact with the upper surface of the vehicle body member, and the radar bracket is supported by the vehicle body member, so that the sagging of the bumper due to its own weight can be suppressed or prevented. Thus, since the irradiation direction of the electric wave irradiated from the radar does not deviate from the predetermined direction, it is possible to prevent false detection or undetected by the radar from occurring, for example, by the bumper sagging due to its own weight and the irradiation direction of the electric wave being downward. The radar mount may have a frame portion having a recess having the same shape as the outer shape of the radar and holding the radar by the radar being fitted into the recess, and a radio wave cover extending laterally from the inside and the outside in the vehicle width direction in the frame portion and limiting an irradiation area of a radio wave irradiated from the radar, and the protruding portion may be provided at a lower portion of the radio wave cover so as to protrude downward. According to this configuration, even if the wave irradiated from the radar is reflected by not transmitting the bumper, the wave may return to the radar side from an unexpected direction by multiple reflection on the inner side of the bumper, but the wave cover prevents the unnecessary reflected wave from entering the radar, which is advantageous in preventing false detection or false reaction by the radar. Accordingly, the degree of freedom in design (shape, etc.) of the bumper is not easily restricted. Further, the radio wave cover can prevent snow, mud, stepping stones, or the like from entering the radio wave irradiation area in the opposing space between the bumper and the radar. The radar mount may be configured such that a rib for preventing deflection is provided on the rear surface of the rear wall of the frame. According to this configuration, since the rigidity of the radar bracket is improved, the radar bracket can be prevented from being deformed when the radar bracket is assembled to the bumper, and besides, for example, the bumper can be prevented from being dented by a light collision. Thus, the irradiation direction of the electric wave irradiated from the radar is not easily deviated. The radar mount may be configured such that the radio wave cover is made of a conductive resin that easily reflects and absorbs radio waves. According to this configuration, as in the case where the electric wave irradiated from the radar is reflected without being transmitted through the bumper, the effect of preventing the radar from being incident from an unexpected direction by multiple reflection on the inside of the bumper can be improved. This results in an improvement in the effect of preventing false detection or false reaction by the radar. The radar mount may be configured such that a rear wall of the frame portion is formed with the frame portion body and is attached to the frame portion so that a rear surface side of a recess of the frame portion can be opened or closed. According to this configuration, even after the radar bracket is attached to the bumper, the radar can be easily attached to and detached from the radar bracket, and therefore, the operability, for example, when the radar bracket is attached to the vehicle or when the radar attached to the radar bracket is replaced with a new radar, is improved. Further, since the rear wall is configured to be openable and closable by a simple structure using only t
