Water spraying device capable of automatically stretching and rotating

Abstract

The invention relates to a water spraying device capable of automatically stretching and rotating. The device comprises a device shell, a spraying body is arranged in the device shell, the upper end and the lower end of the spraying body are communicated with a spraying body cover and a nozzle column respectively, the spraying body cover is connected with an external water pipe, and a steel sleeve, a spring and a nozzle capable of popping up and retracting by means of water pressure in the spraying body are arranged in the spraying body, the spraying body is fixedly connected with a driven gear, a driving gear is meshed with the driven gear, the motor shaft of a motor is in key connection with the driving gear, and a whole vehicle BCM controller is in control connection with the motor. According to the water spraying device, when a driver starts a water spraying function, the nozzle automatically stretches out to spray a columnar water column with a stable angle, automatic reciprocating rotary spraying can be achieved, the spraying area of washing liquid on windshield glass is greatly increased compared with a traditional column shape and a traditional fan shape, the nozzle is automatically contracted into the device shell when water is not sprayed, and the nozzle is effectively hidden; and the double functions of automatic stretching and automatic rotating are synchronously achieved, the appearance feeling and the high-end feeling of the whole automobile can be greatly improved, and the device is small in mechanism and flexible in arrangement position.

Description

technical field [0001] The invention belongs to the technical field of automobile parts, and in particular relates to a water spray device that can automatically expand and rotate. Background technique [0002] The rear windshield of SUV hatchback models in the automotive field is prone to dust accumulation, which affects the driver's rear view. Therefore, most models are equipped with a rear cleaning system. The rear cleaning nozzle sprays washing liquid on the rear windshi The glass is wiped clean. The wiper track of the rear wiper is fan-shaped. When the rear wiper wipes, there needs to be a certain amount of water or washing liquid on the rear windshield glass to lubricate, otherwise the dry wipe of the rear wiper will easily cause damage to the blade and shorten the The life of the scraper is too long, and the scraping is not clean. The rear nozzle structure is usually arranged on the rear spoiler. For the sake of aesthetics, the rear nozzle structure is hidden in the...
