Abstract
The invention discloses a self-contained matching type nozzle spraying device which comprises a nozzle (3), wherein the nozzle is arranged on a long arm (2) through a nozzle clamp (1), the lower part of the nozzle is fixedly arranged on the nozzle clamp through a fastening piece (4), and the front part of the nozzle is provided with a plurality of nozzle openings (6). The through hole at the outer end part of the nozzle is embedded with a steel ball to prevent water leakage at the through hole. The nozzle is directly arranged on the long arm of the framework scraping blade of the windscreen wiper through the nozzle hoop, so that the universality is strong, and the influence of the shapes of a windshield, an engine cover plate, a ventilation cover plate or a scraping rod of an automobile is avoided; the water outlet speed is high, the spraying range is large, the size of the windshield can be freely adjusted according to different vehicle types, and the spraying requirement of special vehicle types is effectively met; the automobile windshield mold has the advantages of multiple injection points, wide glass covering surface and short injection distance, and does not need to meet the requirement of matching the automobile body by newly opening a new mold according to different sizes and positions of automobile windshields. The device can be commonly used on passenger vehicles and commercial vehicles.
Description
Technical Field
The invention relates to an automobile wiper system, in particular to a nozzle injection device.
Background
At present, a wiper (also called a wiper) is an indispensable component of an automobile, and a wiper arm assembly of the wiper is used for receiving power transmitted by a wiper motor and a link mechanism and generating pressure of the wiper arm, and a wiper blade of a wiper blade framework is used for wiping a windshield so as to clean foreign matters on the windshield. For a passenger vehicle, a nozzle injection device matched with a windscreen wiper is assembled on an engine hood plate and a ventilating hood plate of the vehicle, the number of injection points is small (generally only 2-3), the injection position is fixed, the coverage area of an injection windshield is small, the injection distance is long, and the like, the appearance of the vehicle is influenced to a certain extent, whether the arrangement positions of a scraping arm and a scraping blade influence the injection track and avoid the interference phenomenon is also considered when the engine hood plate and the ventilating hood plate of the vehicle are assembled and arranged, the universality of the nozzle injection device is reduced according to the positions of the windshield and the shape of the engine hood plate, and the mold cost is increased; for a commercial vehicle, a nozzle injection device matched with a windscreen wiper is assembled at the front end of a scraping rod of the windscreen wiper, the problems of few injection points and fixed injection position are solved, and the risk of interference between the shape of the scraping rod and a scraping arm and the nozzle injection device in the scraping and brushing process needs to be considered.
Disclosure of Invention
The present invention is directed to overcome the above-mentioned technical deficiencies and to provide a self-contained nozzle-spraying device in which a nozzle is directly mounted on a long arm of a blade frame.
The purpose of the invention can be realized by the following technical scheme: from supporting formula nozzle injection apparatus in area, including the nozzle, the nozzle passes through the nozzle clamp dress on the long arm, the lower part of nozzle is by fastener fixed mounting on the nozzle clamp, the front portion of nozzle has a plurality of nozzle openings.
The through hole at the outer end part of the nozzle is embedded with a steel ball to prevent water leakage at the through hole.
After the invention is adopted, the nozzle is directly arranged on the long arm of the scraping blade framework through the nozzle hoop, so that the universality is strong, the influence of the modeling of the automobile windshield, the engine cover plate, the ventilation cover plate or the scraping rod is avoided, and the modeling requirements of other parts of the automobile are not influenced; the water spray device is directly assembled on the scraping blade framework, has quick water outlet and large spray range, can be freely adjusted according to the sizes of windshields of different vehicle types, and effectively meets the spray requirement of special vehicle types; the automobile windshield mold has the advantages of multiple spraying points, wide glass covering surface, short spraying distance and quick water outlet, and does not need to be newly developed according to the different sizes and positions of automobile windshields to meet the requirements of matching automobile bodies. The device can be commonly used on passenger vehicles and commercial vehicles.

Detailed Description
The invention is described in further detail below with reference to the figures and the detailed description.
Referring to fig. 1 to 3, the self-contained nozzle spray device of the present invention includes a nozzle 3, the nozzle 3 is mounted on a long arm 2 through a nozzle yoke 1 (two pieces in bilateral symmetry), the lower portion of the nozzle 3 is fixedly mounted on the nozzle yoke 1 by a fastening member 4, and the front portion of the nozzle 3 has a plurality of nozzle openings 6 (i.e., spray holes, directed toward a windshield to be cleaned). The steel ball 5 is embedded in the through hole at the outer end part of the nozzle 3 to prevent water leakage at the through hole.
The general scraping blade framework of the existing windscreen wiper comprises a long arm, a transition arm and a short arm, wherein a scraping blade is arranged on the short arm, and the long arm is connected with a scraping rod of a scraping arm assembly. The invention can be directly assembled on the general wiper blade framework of the existing windscreen wiper, can be applied to the long arms of various wiper blade frameworks, and each wiper blade framework can be provided with the nozzle injection device: the method comprises the following steps that (1) nozzle hoops 1 which are bilaterally symmetrical are designed and fixed on long arms by utilizing the same interval of the molding holes of the universal long arms 2 on the existing doctor blade framework (detailed figure 1), and the nozzle hoops are clamped into the interval between the molding holes of the long arms through the structures of two barbs and the limiting positions at the lower ends (detailed figure 2); the nozzle 3 is molded by adopting a PA66 material die, the corresponding nozzle length is selected according to the length of the long arm, the nozzle 3 penetrates into two bilaterally symmetrical nozzle clamps, the fixed distance can be freely adjusted according to the requirement of the spraying position, and the nozzle is fixed on the nozzle clamp 1 through a fastener 4 (a cross-recessed pan head self-tapping screw) (see figure 2 in detail).
The steel ball 5 (shown in detail in figure 3) is embedded in the through hole at the outer end part (namely the front end) of the nozzle 3, so that water leakage at the through hole can be effectively prevented. The front end and the rear end of the nozzle are inclined planes, the angle and the aperture size of a nozzle opening 6 (jet hole) of the nozzle can be adjusted by the rotary hole device at the later stage according to the position requirement of a windshield jet point, the quantity and the aperture size of the jet hole can also be adjusted by the middle section of the nozzle according to the actual requirement of the windshield of a vehicle body, and the tail end size of the nozzle (similar to a water pipe) can also be freely processed and matched with corresponding size by a lathe device according to the pipe diameter size of the nozzle.
