Description
Technical field
The utility model relates to vehicle electric motor field more particularly to a kind of motor resolver shields.
Background technique
A kind of countries in the world environmental protective measure is increasingly stringenter, and substitutes regular fuel engine automobile with eco-friendly car
The mainstream of development of automobile from now on will be become, government also continues to increase the encouragement supporting dynamics of new-energy automobile industry.
Current each state all pays much attention to the development of electric car, position, velocity pick-up used in electric automobile motor
Device is all rotary transformer, therefore, particularly important to the protection of rotary transformer.Existing rotary transformer safeguard procedures pass through
The structure of casing designs, and without individual shield protection mechanism, signal increases the difficulty of design electric motor structure vulnerable to interference
Degree, while certain machine upkeep measure is not also formed to rotary transformer, seriously affect its service life.
Summary of the invention
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of protection of motor resolver
Cover, thus protect motor resolver well, reduce signal interference, and not will receive dust, greasy dirt etc.
Influence, and then rotary transformer service life increase, failure rate reduce.
To achieve the above object, the utility model uses technical solution below:
A kind of motor resolver shield, including protection cover main body, the shield body shape are similar for circle
Shape bottle cap, shield body openings end extend in parallel to form belt side around, and the protection cover main body extends to side
Interconnecting piece is formed, the interconnecting piece extends to form the first extension edge outward, and first extension edge is L-shape, and and interconnecting piece
Form the first groove；
The belt side is equipped with threaded hole, and the motor resolver shield is fixed on electronic by screw element
On machine rotary transformer；
The interconnecting piece both ends are respectively equipped with the first lug boss and the second lug boss, first lug boss and the second protrusion
Portion's surfacing.
Using the protection cover main body of similar circular bottle cap in the utility model, primarily to the knot of matching rotation transformer
Structure design, so that space hold minimizes, being equipped with the first lug boss and the second lug boss, there are two effects: first is that shield and electricity
Motivation rotary transformer needs when fixed by screw element using gasket, and such shield passes through the first lug boss and the second protrusion
Portion be still able to be close to rotary transformer, second is that need to rotary transformer there are draw space of lines, but there are draw space of lines
Necessarily making shield, there are gaps, to influence protection of the shield to rotary transformer, therefore, are additionally provided with the first extension
The gap reserved by extraction space of lines is transferred to the place that cannot be directly communicated to rotary transformer by side.
Preferably, the belt side is equipped with threaded hole A, threaded hole B and threaded hole C, the threaded hole A and threaded hole
B is closed threaded hole and close interconnecting piece, and the threaded hole C is open threaded hole and is located at shield with interconnecting piece
The both ends of main body.It is fixed in motor resolver using three bolts, ensure that stability, the safety of protection, together
When threaded hole C use open bolt fixing method, primarily to being conveniently adjusted and installing.
Preferably, first lug boss extends outward to form the second extension edge, second extension edge and first convex
Rise portion upper surface flush and with connect lower surface and outer surface flushes.It is to will more easily draw equipped with the second extension edge
Space of lines there are gap be transferred to the other side.
Preferably, second lug boss extends outward to form third extension edge, the third extension edge and interconnecting piece
Lower surface flushes, and the third extension edge, which is connected with the first extension edge and is formed in side, to be closed.
More preferably, first extension edge and third extension edge lower surface are fitted tightly over motor resolver
On.
It should accomplish the Seal treatment to rotary transformer as far as possible in the installation process of shield, therefore only be stayed in structure
There is the gap of the second extension edge, third extension edge, which is connected with the first extension edge and is formed in side, to be closed, and described first extends
Side and third extension edge lower surface are fitted tightly in motor resolver.
Preferably, the motor resolver shield is integrally formed.
Preferably, the motor resolver protection cover material is aluminum profile.Aluminum profile is preventing electromagnetism and electricity
The signal interference this respect of stream has good effect.
The utility model has carried out both sides list due to the technical solution more than using, to motor resolver
Solely protection, first, protect interference of the motor control signal not by electric current, electromagnetism；Second, to the mechanical protection of rotary transformer,
The influence that not will receive dust, greasy dirt etc., extends service life.
