Wherein, this technical scheme utilizes the electromagnet characteristic, adopts electromagnet and magnetism to inhale the main part that the piece was gone up and down as realizing the wiper arm pole, simple structure, simple to operate.
In order to strengthen the magnetic attraction of the electromagnet, the lower end of the electromagnet is provided with a circle of annular boss, the annular boss and the magnetic core of the electromagnet are integrated, when the electromagnet is electrified, the annular boss is also magnetic and attracts the annular iron sheet to move downwards, the annular boss is connected with one end of the elastic telescopic external member towards one side of the annular iron sheet, and the other end of the elastic telescopic external member is connected on the annular iron sheet.
Further, the outer diameter of the annular boss is the same as that of the annular iron sheet.
Furthermore, the elastic telescopic sleeve is a spring, so that materials are convenient to select, the adaptability is good, and the cost is low.
Furthermore, the electromagnet is an electromagnet, and in order to enable the electromagnet to be demagnetized immediately after being powered off, the iron core material of the electromagnet is soft iron or silicon steel.
The technical scheme of the utility model a wiper is still provided, and this wiper includes foretell wiper arm.
The technical scheme of the utility model a vehicle is still provided, and this vehicle includes foretell wiper.
Compared with the prior art, the beneficial effects of the utility model are that:
according to the technical scheme, the electromagnet, the elastic telescopic sleeve and the magnetic suction piece are arranged at one end of the arm rod of the windscreen wiper, when the windscreen wiper does not work, the electromagnet is not electrified, and under the action of the elastic telescopic sleeve, the distance between the arm rod of the windscreen wiper and glass is increased, so that a certain distance can be kept between a windscreen wiper rubber strip and the glass, the temperature change of the glass is prevented from accelerating the ageing of the rubber strip, and the service life of the rubber strip is prolonged; when the windscreen wiper works, the electromagnet is electrified, the magnetic suction piece drives the windscreen wiper arm rod to move downwards, the distance between the windscreen wiper arm rod and glass is shortened, and the windscreen wiper rubber strip is in contact with the glass, so that the glass is cleaned.
