Abstract
The utility model relates to an anti-electromagnetic interference device of a window lifter motor, which comprises a circuit board (2) and a metallic sheath (3) which is sheathed on a casing (1.1) of the motor (1), wherein the circuit board (2) is provided with a filter circuit (2.1); both ends of the filter circuit (2.1) are respectively and electrically connected to binding posts (1.3) of two power supplies on the motor (1). Compared with the prior art, the anti-electromagnetic interference device comprises the circuit board arranged on the motor and the metallic sheath which is sheathed on the casing, the circuit board is provided with the filter circuit, electromagnetic waves generated by the window lifter motor are shielded by the filter circuit on the circuit board, whereas electromagnetic interference generated by a coil of the window lifter motor is shielded by the metallic sheath on the casing of the motor, therefore, the electromagnetic interference generated by the window lifter motor is completely shielded, and the normal use of other vehicle-mounted electronic equipment or systems cannot be influenced. At the same time, the outside electromagnetic interference is also shielded by the filter circuit and the metallic sheath, and thereby, the influence of the outside electromagnetic interference on the operation of the window lifter motor is avoided.
Description
Technical field:
The present invention relates to relate to a kind of electromagnetic interference resistant device that shakes the window motor that is used for the automobile door and window glass lifting.
Background technology:
At present, along with science and technology development, the electronic equipment of equipping on the automobile is also more and more, and is more and more advanced.Because the electromagnetic wave that motor produces propagates in vehicle-mounted other electronic equipment or system by the mode of conduction, coupling or radiation, thereby disturb normal operation of these electronic equipments or system and result of use when work.Shake the window motor such as prior art, in the process that door glass rises and descends, shake the electromagnetic wave that the window motor produces, will disturb the result of use of other vehicle-mounted advanced electronics, as when listening to radio broadcasting, will produce a kind of very difficult noise of listening, allow the people feel very ill; Meanwhile, the electromagnetic wave that other electronic equipment or system send can make that also shaking the window motor produces the very difficult noise of listening when work.
The utility model content:
The technical problem to be solved in the present invention provides a kind of electromagnetic wave that can effectively eliminate the motor generation, and can shield the electromagnetic interference resistant device that shakes the window motor of outside electromagnetic interference.
The present invention overcomes the above problems used technical scheme: a kind of electromagnetic interference resistant device that shakes the window motor is provided, it comprises wiring board and the metallic sheath that is enclosed within on the motor housing, described wiring board is provided with filter circuit, and the two ends of described filter circuit are electrically connected with the binding post of two power supplys on the motor respectively.
Described wiring board is located on the motor.
Compared with prior art, because the utility model has adopted it to comprise and has been located at wiring board and the metallic sheath that is enclosed within on the motor housing on the motor, described wiring board is provided with filter circuit, the two ends of described filter circuit are electrically connected with the binding post of two power supplys on the motor respectively, then the filter circuit on the wiring board makes and shakes the electromagnetic wave conductively-closed that the window motor produces, and the feasible electromagnetic interference conductively-closed of shaking the generation of window motor coil of the metallic sheath on the motor housing, shielded fully so shake the electromagnetic interference of window motor generation, also just can not influenced other the vehicle-mounted electronic equipment or the normal use of system; Meanwhile, filter circuit and metallic sheath have avoided outside electromagnetic interference to shaking the influence of window motor rotation also with the electromagnetic interference shield in the external world.
As improvement, described wiring board is located at the motor end, and then this just shortens the distance of filter circuit and binding post on the wiring board, helps electromagnetic wave and extraneous electromagnetic interference that complete shield electric machine produces, also saved simultaneously the lead that connects, helped further reducing production costs.
As further improvement, described filter circuit comprises at least two electric capacity, and described electric capacity is in parallel each other, and two ends separately are electrically connected with the binding post of two power supplys on the motor respectively, described electric capacity is two, and then the filter circuit of this structure is simpler, and cost is lower; And be provided with the better effects if of filtering behind two electric capacity, so help improving performance of the present utility model.
As further improving, described metallic sheath is the silicon steel cover again, and then the characteristic of silicon steel cover itself makes that shield electromagnetic interference performance of the present utility model is better.
As further improving, the sidewall opening of described silicon steel cover, then the cover of the silicon steel behind the opening is installed more convenient, because silicon steel cover self rubber-like characteristic, so after strutting the silicon steel cover, the internal diameter of silicon steel cover is just bigger, like this than being easier to be nested on the motor housing, and decontrol after being nested into the appropriate location, the silicon steel cover is returned to original state just to be had and has formed a closed relatively collar, so also do not influence original shield electromagnetic interference performance.
