When static contact 1 freezes, control drive module 5 starts, to drive movable contact spring 2 to vibrate.Wherein, drive module 5 can be vibration
Device.Using above-mentioned electromagnetic switch, avoids motor and do not work, the case where vehicle can not start.
The present invention includes static contact 1, movable contact spring 2, deicing structure 3, drive module 5 and control unit 10, when 1 knot of static contact
When ice causes circuit obstructed, control unit 10 controls the driving of drive module 5 will be on static contact 1 to be vibrated by deicing structure 3
Ice cube removal.Using the deicing mode of vibration, faster, deicing is more thorough for speed.
Fig. 2 is the schematic diagram of motor according to an embodiment of the invention.As shown in Fig. 2, and referring to Fig. 1, electricity
Magnetic switch 100 further includes dynamic iron core 20, in electromagnetic switch 100 movable contact spring 2 under the drive of dynamic iron core 20 with static contact 1 conducting/
Separation, to realize being turned on/off for electromagnetic switch 100.
Fig. 3 is the control principle drawing of drive module according to an embodiment of the invention.As shown in figure 3, simultaneously referring to fig. 2,
Since temperature will form condensed water on static contact 1, work as electromagnetism there are due to temperature difference in ambient temperature and electromagnetic switch 100
When temperature and humidity in switch 100 meets ice-formation condition, the condensed water on static contact 1 can freeze, and be closed in electromagnetic switch 100
Afterwards, electric current can be caused obstructed so that 200 fail to start of motor because there is ice sheet on static contact 1.Therefore it needs to judge on static contact 1
Whether there is ice sheet and cause motor 200 that cannot start, so temperature sensor 7 and humidity sensor are arranged in electromagnetic switch 100
Device 8.Temperature sensor 7 is used to detect the temperature in electromagnetic switch 100, and humidity sensor 8 is for detecting in electromagnetic switch 100
Humidity.Electromagnetic switch 100 is arranged in motor 200, speed probe 9 is provided in motor 200, for detecting motor 200
Revolving speed.Control unit 10 is configured to after electromagnetic switch 100 is opened, and the temperature in electromagnetic switch 100 is lower than zero degree, electromagnetism
Humidity in switch 100 determines that the surface of static contact 1 freezes lower than threshold temperature and in the case that motor speed is zero.Namely
It says, using the speed conditions of motor 200, the unlocking condition of the environmental condition of icing and electromagnetic switch 100 and to judge stationary contact
Whether piece 1 freezes.Specifically, temperature sensor 7 will test temperature information, the humidity information that humidity sensor 8 will test,
The rotary speed information that speed probe 9 will test feeds back to control unit 10, control unit 10 according to the temperature information received,
Humidity information and rotary speed information judge whether that controlling drive module 5 opens, and can accurately more judge electricity using this feedback path
Whether the static contact 1 in magnetic switch 100 freezes, and deicing reacts faster.It avoids in the case that static contact 1 does not freeze and drives simultaneously
Dynamic model block 5 works, and has saved electric cost.
After control unit 10 determines that static contact 1 freezes, control unit 10 controls drive module 5 and movable contact spring 2 is driven to vibrate
Further driving deicing structure 3 is vibrated, and is finally reached the purpose for removing 1 surface ice sheet of static contact, guarantees deicing structure 3 and stationary contact
Piece 1 contacts, and static contact 1 and movable contact spring 2, which is connected, further connects motor body circuit, and motor 200 rotates.Work as revolution speed sensing
Device 9, which detects, illustrates that deicing structure 3 removes the ice sheet on static contact 1 after motor 200 rotates, and speed probe 9 should
Rotary speed information feeds back to control unit 10, and control unit 10 controls drive module 5 and closes.
In another embodiment, deicing structure 3 is including where multiple surfaces by movable contact spring 2 towards static contact 1
The convex block 31 to be formed is protruded in direction, and using convex block 31, area occupied is small, and uses multi-point design, improves contact area, avoids
The moment of current turns ON generates high energy heat and melts static contact 1 and 3 part of deicing structure, is needing static contact 1 and deicing knot
It cannot be separated both when structure 3 separates, making motor, there are security risks.
Further, convex block 31 gradually becomes smaller along the cross section of its protrusion direction, and specifically, convex block 31 is along 2 court of movable contact spring
Gradually become smaller to the direction cross section of static contact 1, can more rapidly deicing, improve deicing effect.
Preferably, convex block 31 is tapered.Using the dentation of convex block 31, ice-breaking capacity can be improved, it can be by ice cube faster
Speed is chiseled.
Fig. 4 is the schematic plan of deicing structure in electromagnetic switch according to an embodiment of the invention, and Fig. 5 is basis
The Some illustrative cross-sectional view of the electromagnetic switch of one embodiment of the invention.As illustrated in figures 4-5, and referring to Fig.1.Multiple convex blocks 31
The one side being decorated in array in movable contact spring 2 towards static contact 1, multiple convex blocks 31 are connected two-by-two, so that multiple convex blocks 31 are with most
More quantity occupies least area and is arranged on movable contact spring 2.In addition, multiple convex blocks 31 are in movable contact spring 26 towards static contact 1
Side arranges to form placement-face, and placement-face is greater than area of the static contact 1 towards 2 side of movable contact spring, and being conducive to will be on static contact 1
Ice cube more completely removes.
Electromagnetic switch 100 further includes movable feeler lever 6, and movable feeler lever 6 has opposite two sides, and side is connected with movable contact spring 2, moves touching
Bar 2 is internally provided with the accommodating chamber 4 for installing drive module 5.The control in the case where static contact 1 freezes of control unit 10 is driven
