Abstract

The invention relates to the technical field of automobile manufacturing, in particular to a graphene defrosting windshield wiper. The graphene defrosting windshield wiper comprises a driving power source, a swinging arm and a wiper, wherein the wiper comprises a wiper frame and a wiper core; the wiper core comprises an inner protective layer, a graphene heating layer and a soft wiping layer; a heating electrode of the graphene heating layer is closely connected to an electrode of a built-in power source of an insulating protruding part at the inner side of the wiper frame, and communicates with the vehicle-mounted driving power source along the middle of the swinging arm; a driving motor is provided with at least a high speed option and a low speed option to control the angular speed of the swinging of the swinging arm; the angular speed of the swinging of the swinging arm is 5-30 radians per second when the low speed option is selected; and at the same time, a heating power source isconnected and the wiper is heated through the graphene heating layer so as to melt the frost on a front windshield of an automobile. The graphene defrosting windshield wiper disclosed by the invention instantaneously heats and defrosts a graphene heating film in the wiper core of the windshield wiper by virtue of the vehicle-mounted power source, and is fast, effective, compatible with an existing vehicle-mounted windshield wiper system, easy to replace, and convenient for people to drive the automobile in the winter mornings.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a graphene defrosting wiper. Background technique [0002] When the outdoor temperature is low in winter, the car glass is often covered with a layer of ice crystals. If you urgently need to go out to do errands in the morning, it will take a long time to melt the frost covering the glass through the slow heating of the car air conditioner, which is labor-intensive, fuel-intensive and time-consuming. In an emergency, people often use hot water to defrost, apply hot towels or scrape to defrost, and the use of hot water to defrost often causes the glass to break due to the sharp increase in temperature difference. Using hot towels to apply and wipe is not only very troublesome but also often Because the temperature is too low to repeatedly freeze, it is neither thorough nor convenient to use a scraper to defrost. People have been looking for a quick, convenient a...
