Sensor framework assembly, wheel speed sensor and motor vehicle

Abstract

The invention relates to a sensor framework assembly. A sensor framework comprises a framework body (13) and at least two riveting inserts (3), wherein a hollow structure (14) is arranged at the middle part of the framework body (13); the hollow structure (14) forms a cavity structure by an inverted truncated cone shaped through opening. The sensor framework is capable of improving residual stress in the injection molding process of the conventional integrated framework, better guiding the flowing direction of an injection molding material and balancing impact force in the injection molding process. The invention also relates to a wheel speed sensor with the framework assembly and a motor vehicle comprising the wheel speed sensor.

Description

technical field [0001] The invention relates to sensor technology, in particular to a sensor skeleton assembly, a wheel speed sensor with the sensor skeleton assembly and a motor vehicle with the wheel speed sensor. Background technique [0002] In the Chinese utility model patent CN202903813U, an ABS wheel speed sensor skeleton assembly is disclosed, which includes a magnetic steel, an insert I, an insert II and a skeleton injection molded body, and the insert I and insert II are embedded in the upper end of the skeleton injection molded body And expose the part connected with the cable and the part where the chip is welded, wherein the magnetic steel is inlaid and injected at the lower end of the skeleton injection molding body, and there is a groove for the chip to be inserted from the side on the skeleton injection molding body under the magnet steel . [0003] To a certain extent, the existing sensor framework can meet the general functional requirements of wheel speed...

Problems solved by technology

For example, traditional bobbins generally only perform functional matching on a single wire diameter, while today's market is dominated by personalized customized products, and traditional special bobbin assemblies do not have the flexibility of matching

In addition, the traditional skeleton is fixed by single or double point positioning, and the fixed effect is achieved by pressing with a specific mold, but there are still certain risks in its processing stability.
