Abstract

The invention discloses a magnetic induction module for an automobile neutral-gear switch and a manufacture method thereof; samarium cobalt magnet steel (1) is put into a lining part (2) to be precisely located; and then, a magnet steel combination and a copper sleeve (3) are put into another pair of plastic moulds to be injected for the second time, so that an integral body is formed. The structure of the magnetic induction module is formed by utilizing an injection mould; the manufacture efficiency and the size precision of the magnetic induction module for the neutral-gear switch are greatly increased; multiple disadvantages in filling and sealing by using epoxy resin adhesive in the traditional manufacture process are avoided; the manufacture cost of the product is reduced; and the quality and the reliably of the product are increased.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a magnetic induction module of an automobile neutral switch and a manufacturing method thereof. Background technique [0002] In recent years, with the rapid development of automobile intelligent technology, some OEMs are more and more inclined to the research of new technologies such as intelligent start and stop, one-button start and keyless entry. The neutral switch is a must-have product for these technologies, and the magnetic induction module It is an essential part of the neutral switch. At present, the non-contact neutral switch technology is still monopolized by some large foreign companies. It is still in its infancy in our country. The traditional process is potted with epoxy resin. [0003] In the process of realizing the present invention, the inventors found at least the following problems in the prior art: the manufacture of epoxy resin potting is inconvenient,...
