Reversing radar sensor and manufacturing method thereof

Abstract

The invention relates to a reversing radar sensor and a manufacturing method thereof. The sensor comprises a cavity and a probe assembly installed in the cavity. The probe assembly includes a front cover, a probe core arranged in the front cover, and an inner container arranged between the front cover and the probe core and has a structure in which the inner container is integrated with the front cover and the probe core by injection molding and fusing. Because the probe assembly has the structure in which the inner container is integrated with the front cover and the probe core by injection molding and fusing instead of a structure based on the assembling mode like an interference fit, thereby reducing the assembling procedures of the probe assembly; and the structure becomes compact and reliable. In addition, because of close integration of the inner container with the front cover and the probe core during injection molding and fusing, water entrance between the probe core and the inner container can be prevented, so that the sensing performance becomes secure and reliable, the service life is prolonged; the product rework phenomenon is avoided, the cost is lowered, and the production efficiency is improve.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a reversing radar sensor and a manufacturing method thereof. Background technique [0002] At present, with the improvement of people's living standards and the improvement of modern road construction, in addition to real estate, automobiles are becoming one of the main consumer markets and the focus of attention of the public today. As a result, China is becoming the most popular market position that global automakers are vying to seize. With the development of science and technology, the proportion of reversing radar sensors used in automobiles is increasing. Basically, low-end, middle-end and high-end cars use standard equipment. The reversing radar sensor is generally installed on the front or rear bumper of the car to detect the distance between the car body and the obstacle, and transmit it to the display screen in front of the driver's seat for display or through the b...

AI Technical Summary

Problems solved by technology

[0004]1. The assembly method of the reversing radar sensor is complicated, and it is difficult to realize the automatic production of machines;

[0005]2. These spare parts are prone to water ingress, requiring a waterproof level above IPX7, but it is difficult for products manufactured by traditional production processes to reach this level, so the existing Frequent rework occurs in production;

[0006]3. When installing spare parts, such as when plastic parts are assembled, through interference fit, it is easy to have poor installation, which is not conducive to product consistency
