Abstract
The utility model relates to a kind of Vehicular wiper electric machine, solves the electromagnetic disturbance technical problem of wiper motor to other electric components in automobile.A kind of Vehicular wiper electric machine comprises motor (2) and 2 electromagnetic compatibility modules (1); Motor (2) adopts magneto brush DC motors, and 2 electromagnetic compatibility modules (1) are separately fixed at magneto brush DC motors speed end and low speed end; Electromagnetic compatibility module is connected with motor internal circuit by wire, electromagnetic compatibility module can filtered motor produce transient voltage, reduce motor to the electromagnetic interference of automobile inner electronic equipment.
Description
Technical field
The utility model belongs to technical field of vehicle, is specifically related to a kind of Vehicular wiper electric machine.
Background technology
Existing wiper motor is magneto brush DC motors, this type of motor provides power for wiper motion, this type of motor has that structure is simple, reliable, volume is little, quality is light, volume is little, loss is little, efficiency is high and the distinguishing feature such as shape and size are versatile and flexible, so apply very extensive in the automotive industry, possess high speed, low speed, intermittently, the basic function of reset.
Because existing wiper motor is inductive devices, switching on and off in process, anti-phase transient voltage can be produced, this amplitude along time variant voltage, up to hundreds of volt, by power line with conduction interference and radiation disturbance, disturbs the normal work of automobile inner electronic equipment, and the rotor of wiper motor is in the process rotated, contact condition between brush and commutator segment sharply changes, and forms sparkover, forms electromagnetic radiation harassing and wrecking.
Utility model content
The purpose of this utility model is to provide a kind of Vehicular wiper electric machine, solves the electromagnetic disturbance technical problem of wiper motor to other electric components in automobile.
The technical solution of the utility model is, a kind of Vehicular wiper electric machine comprises motor and 2 electromagnetic compatibility modules; Motor adopts magneto brush DC motors, and 2 electromagnetic compatibility modules are separately fixed at magneto brush DC motors speed end and low speed end; Electromagnetic compatibility module is connected with motor internal circuit by wire, electromagnetic compatibility module can filtered motor produce transient voltage, reduce motor to the electromagnetic interference of automobile inner electronic equipment.
The beneficial effects of the utility model are, the utility model adopts electromagnetic compatibility module and wiper motor to be fixed on one, convenient installation is fixed, do not take installing space simultaneously, similar with common motor size, eliminate wiper motor operationally to the electromagnetic disturbance of other electric components on vehicle simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Vehicular wiper electric machine of the utility model;
Fig. 2 is the schematic diagram of a kind of Vehicular wiper electric machine of the utility model.
Embodiment
A kind of Vehicular wiper electric machine of the utility model comprises motor 2 and 2 electromagnetic compatibility modules 1.Motor 2 adopts magneto brush DC motors, and 2 electromagnetic compatibility modules 1 are separately fixed at magneto brush DC motors speed end and low speed end.
The design of motor, compared with current common wiper motor, original motor adds electromagnetic compatibility module, is formed integrally after assembling with motor.As shown in Figure 2, principle is for be connected to an electromagnetic compatibility module 1 respectively in motor speed end and low speed end respectively.The electromagnetism interference to external world that electromagnetic compatibility module produces for suppressing and weaken motor.
Electromagnetic compatibility module 1 also can make integrative-structure with motor, and electromagnetic compatibility module 1 is connected with motor internal circuit by wire, electromagnetic compatibility module 1 can filtered motor produce transient voltage, reduce motor to the interference of automobile inner electronic equipment.
The main cause that wiper motor forms electromagnetic disturbance is the transient voltage formed when its power supply is cut off, and the electric spark formed in operation process.
Rotating speed is higher, and the electromagnetic disturbance of motor is larger, and after applying mechanical load, motor speed reduces, and electromagnetic disturbance reduces.
Also can access suitable filter at wiper motor, the Electro Magnetic Compatibility that amplitude improves wiper motor can be reached.
