Problems solved by technology

Then turn on the air conditioner and blow it for a while, so that the fog can be removed, but this consumes a lot of energy and has a slow effect. When the windshield is used in rainy weather, rainwater adheres to the front windshield and affects driving, and the wiper wiper has a limited cleaning limit, especially when driving at low speeds, there is an insurmountable problem of blurred driving vision, and the hidden danger of driving vision affected by rain and fog cannot be solved.

Abstract

An ultrasonic vibration type front windshield. When the front windshield is used in rainy weather, rainwater adheres to the front windshield and affects driving, and the cleaning limit of the wipers is limited, especially when driving at low speeds, there is a problem of blurred driving vision that is difficult to overcome. The invention includes a composite glass body and an ultrasonic vibration assembly. The composite glass body includes an inner glass body, an explosion-proof layer, an outer glass body, a noise reduction layer and a vibrating piece. The sheets are sequentially bonded together from the inside to the outside. The ultrasonic vibration assembly includes a connecting belt and several ultrasonic transducers. The connecting belt is arranged on the composite glass body along the surrounding direction of the composite glass body. Several ultrasonic transducers are The length direction is evenly distributed on the connecting belt, and each ultrasonic transducer is closely attached to the vibrating plate in the composite glass body. The invention is used in automobiles.

Description

technical field [0001] The invention relates to a front windshield, in particular to an ultrasonic vibration type front windshield. Background technique [0002] When driving a vehicle in rainy or foggy days, the phenomenon of rainwater adhesion and fogging on the front windshield is one of the problems that have always plagued drivers. Once the front windshield is fogged, the line of sight will be obstructed. It is very dangerous to be unable to see the road clearly. It was foggy. Generally speaking, the easiest solution is to use the air conditioner on our vehicle to defog, set the air output of the air conditioner to blow the front windshield, and warm up the car for a little longer until the air conditioner can be started. Then turn on the air conditioner and blow it for a while, so that the fog can be removed, but this consumes a lot of energy and has a slow effect. When the windshield is used in rainy weather, rainwater adheres to the front windshield and affects dr...
