Abstract
The utility model provides an anti-interference automobile fan motor brush holder. The holder comprises a brush holder plate; electric brushes uniformly arranged on the brush holder plate; lug plates fixed below the brush holder plate; and a sealing ring fixed around the brush holder plate. The lug plates are divided into a power supply lug plate used for connecting a power supply and an electric appliance element, and an intermediate lug plate used for connecting other electric appliance elements. The holder further comprises metal coils mounted between the two adjacent electric brushes on the brush holder plate. The two ends of each metal coil are respectively connected with the power supply lug plate and the intermediate lug plate. Electromagnetic rods are plugged inside the metal coils. The beneficial effects of the anti-interference automobile fan motor brush holder are that a filtering loop formed inside a motor matches with the pulse frequency generated by the motor, thereby enabling the motor to have the anti-interference capability; and the motor brush holder is convenient to process, simple in structure, low in processing cost, and obvious in anti-interference effect.
Description
Technical field
The utility model belongs to the electric motor of automobile field, especially relates to a kind of anti-interference fan motor for automobile brush holder.
Background technology
Some automobile does not have the Antijamming protecting device in existing technology, and when machine operation, the pulse signal that motor sends has very large interference to the electronic equipment on the automobile, is listening to the radio programme or can hear the noise that pulse frequency is sent during VCD, and quality is driven in impact; When automobile emergency brake or other special circumstances occur, can burn motor in addition, motor is caused potential safety hazard.
Summary of the invention
Problem to be solved in the utility model provides a kind of anti-interference fan motor for automobile brush holder, especially is fit to eliminate in the situation of motor on the vehicle electronics impact use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-interference fan motor for automobile brush holder, comprise brush rack plate, on average be arranged in the brush above the brush rack plate, be fixed on the lug plate below the brush rack plate and be fixed on sealing ring around the brush rack plate, described lug plate is divided into and connects power supply and the power supply wiring sheet of electric elements and the intermediate connection sheet that is connected other electric elements, also comprise and be installed in the wire coil between the two adjacent brushes on the brush rack plate, described wire coil two ends respectively with described power supply wiring sheet be connected the intermediate connection sheet and be connected, electromagnetic wand is plugged in the described wire coil.
Further, the riveted joint of described wire coil two ends and described lug plate or welding.
Further, described lug plate is made of sheet copper.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, the pulse frequency that the filter circuit that forms in motor coupling motor produces makes motor have antijamming capability, motor brush rocker is easy to process, simple in structure, processing cost is low, and anti-jamming effectiveness is obvious.

Fig. 1 is motor brush rocker structural representation of the present utility model
Among the figure:
1, electric wire 2, sealing ring 3, brush rack plate
4, bar magnet 5, wire coil 6, brush
7, intermediate connection sheet tie point 8, power supply wiring sheet tie point
Embodiment
As shown in Figure 1, the utility model is a kind of anti-interference fan motor for automobile brush holder, comprise electric wire 1, brush rack plate 3, on average be arranged in the brush 6 above the brush rack plate, be fixed on the lug plate below the brush rack plate and be fixed on sealing ring 2 around the brush rack plate, described lug plate is divided into and connects power supply and the power supply wiring sheet of electric elements and the intermediate connection sheet that is connected other electric elements, also comprise and be installed in the wire coil 5 between the two adjacent brushes on the brush rack plate, described wire coil 5 two ends are affixed by power supply wiring sheet tie point 8 and intermediate connection sheet tie point 7 respectively, and bar magnet 4 is plugged in the described wire coil 5.
The modes such as described wire coil two ends and the riveted joint of described lug plate or welding are fixed.
Described lug plate is made of sheet copper, and sheet copper can bear larger electric current as lug plate, prevents that motor circuit from damaging, and cost is lower simultaneously.
The electromagnetic wand that connects in the motor rotation loop and wire coil form filter circuit, can protect motor, strengthen the motor interference free performance, prevent the comfortableness that pulse frequency affects use and the driving of car electrics.
Above an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
