Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
See Fig. 1, a kind of magnetic induction module of automobile neutral switch, comprise magnet steel 1, copper sheathing 3 and inner piece 2, magnet steel 1 is connected with inner piece 2, also comprises module bracket 4, and copper sheathing 3, magnet steel 1 are fixed in module bracket 4 with inner piece 2 and form an entirety.
Inner piece 2 is provided with the groove suitable with magnet steel 1, and magnet steel 1 is arranged in groove.As shown in Figure 2.
Groove both sides are provided with the buckle 21 of spacing magnet steel 1.
Magnet steel 1 is SmCo magnet steel 1, and Surface field intensity is greater than 2500 Gausses.
Inner piece 2 material is PA66+GF30, adds 30% glass fibre to PA66 (nylon66 fiber) plastic material.This material has very high toughness and good rigidity, can oil resistant and high-low temperature resistant for a long time, can bear transmission internal complex environment.
A preparation method for the magnetic induction module of above-mentioned automobile neutral switch, comprises following process:
1) magnet steel 1 is fixed on inner piece 2;
2) inner piece 2 of magnet steel 1 and band magnet steel 1 is put into module bracket 4 mould;
3) injection moulding in module bracket 4 mould, forms module bracket 4, and the coated copper sheathing 3 of module bracket 4, magnet steel 1 and inner piece 2, form an entirety.Product stable magnetic field is reliable, and magnet steel 1 is not easily broken, and profile is simple, easy for installation, safe and reliable.As shown in Figure 3.Realize the exact position of magnetic induction block magnet steel 1 and the stable of magnetic field intensity.
The locating piece of positioning magnetic steel 1 and inner piece 2 is provided with in module bracket 4 mould.For the position of accurate positioning magnetic steel 1 and inner piece 2, thus ensure that the accurate location of SmCo magnet steel 1 in product and the perpendicularity of copper sheathing 3 end face.Copper sheathing 3 location in a mold and product shaping picture in a mold, the dimensional accuracy of product is gone to ensure by the machining accuracy of mould, and the margin of tolerance of product can control within IT12 level.
As shown in Figure 4, be the structural representation of the installment state of the magnetic induction module of automobile neutral switch.
Can go to realize without epoxide-resin glue embedding from configuration aspects, easily manufactured, because the dimensional accuracy of product parts goes to ensure by mould and die accuracy completely, so the dimensional accuracy of product is very high, due in the lubricating oil that product is immersed in gearbox for a long time and require the high temperature of resistance to 130 degree, plastics can oil resistant and resistance to 130 degree of high temperature for a long time, magnet steel 1 adopts scythe and cobalt kind material, Surface field requirement of strength reaches design parameter, magnetic is very little with the decay of temperature and time, so product carries out sufficient verification experimental verification when selecting part material, product installing/dismounting is very convenient in addition, only need be fixed on selector shaft with the pin of a φ 4.
After adopting above-mentioned structure, SmCo magnet steel 1 is put in inner piece 2 and accurately locate, again magnet steel combination and copper sheathing 3 are placed on secondary injection in another secondary Mold for Plastics and are moulded an entirety, utilize injection molded to realize the structure of magnetic induction module, greatly improve the manufacture efficiency of neutral switch magnetic induction module and the dimensional accuracy of product, avoid the many drawbacks with epoxide-resin glue embedding in conventional fabrication processes, reduce cost of goods manufactured, improve the q&r of product.Ensure that the accurate location of SmCo magnet steel 1 in product and the perpendicularity of copper sheathing 3 end face.Realize the integration of magnetic induction module, magnet steel 1 position is accurate, Surface field intensity stabilization, and it is convenient that product is installed, thus it is reliable and stable to ensure with neutral switch contactless magnetic induction performance.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
