Abstract
The utility model discloses a kind of telescopic wiper of hydraulic pressure, including windscreen wiper base, driving motor, main wiper bar, scalable windscreen wiper bar assembly.Scalable windscreen wiper bar assembly includes the replaceable convex block being removably attachable on the windscreen wiper base, hydraulic cylinder push rod of the slidable connection in the main wiper bar, the pulley being rotatably connected on the hydraulic cylinder push rod, the spring being set between hydraulic cylinder push rod and main wiper bar, scalable floating rule of the slidable connection in the main wiper bar；Wherein, the hydraulic cylinder push rod, the main wiper bar form closed hydraulic cavities between the scalable floating rule.By the convex block swung with being arranged on windscreen wiper base of wiper bar itself, the position of scalable wiper bar is controlled, expands the cleaning area of wiper.The utility model exquisiteness simple in structure, manufacture are at low cost, moreover it is possible to by replacing replaceable convex block, suitable for vehicle window of different shapes.
Description
Technical field
The utility model is related to wiper technical field, particularly a kind of telescopic wiper of hydraulic pressure.
Background technology
The scraping blade of the wiper of automobile is mostly fixed structure at present, and the cleaning range of wiper is limited by arm lengths are scraped
System, and scrape arm lengths and usually determined by many factors such as the structure of wiper, the driving force of driving device, automotive window shapes,
Therefore the wiper with regular length generally can not meet the requirement for cleaning entire vehicle window.
In order to realize the purpose for the cleaning range for expanding wiper, there is partial automobile to employ telescopic wiper.This
Kind of wiper is flexible usually using servo motor and control module driving scraping blade, the control module stretched due to driving scraping blade and
Driving device of the servo motor independently of wiper in itself, therefore structure is complex.
Chinese Patent Application No. is 201420420007.4, and the applying date is that the patent document of 2014.07.28 discloses one kind
Hydraulic pressure retractable automobile wiper, including wiper ontology, the wiper body interior is hollow structure, and the hydraulic pressure can be stretched
Contracting vehicle wiper further includes：It is telescopically arranged in the hairbrush of the wiper body interior；Positioned at the wiper ontology
Interior hydraulic cylinder, the hydraulic cylinder is interior to have piston, and the piston is connected with one end of the hairbrush；It is conveyed to the hydraulic cylinder
The hydraulic motor of hydraulic oil；Wherein, the hairbrush in the hydraulic cylinder by conveying hydraulic oil when, in the drive of the piston
Under, the scalable movement in the wiper ontology.The utility model solves vehicle windscreen wiper and is removing automobile wind shield glass
On dirt when the vehicle glass upper right corner and the lower left corner there are problems that blind area.But above-mentioned utility model stretching structure is by hydraulic pressure
Cylinder and hydraulic motor control, structure is still complex, and production cost is high.
Utility model content
The main purpose of the utility model is that providing, one kind is simple in structure, and production cost is low, is suitable for different shape vehicle
The telescopic wiper of hydraulic pressure of window.
To achieve the above objectives, the technical solution adopted in the utility model is：A kind of telescopic wiper of hydraulic pressure, including
Windscreen wiper base, driving motor, main wiper bar, scalable windscreen wiper bar assembly.Scalable windscreen wiper bar assembly includes removably connecting
The replaceable convex block being connected on windscreen wiper base, hydraulic cylinder push rod of the slidable connection in main wiper bar, is rotatably connected
Pulley on hydraulic cylinder push rod, the spring being set between hydraulic cylinder push rod and main wiper bar, slidable connection is in main wiper bar
Interior scalable floating rule.Wherein, hydraulic cylinder push rod, main wiper bar form closed hydraulic cavities between scalable floating rule.
Preferably, cavity P is formed between hydraulic cylinder push rod and main wiper bar, is formed between scalable floating rule and main wiper bar
Cavity Q, cavity P area of section are more than cavity Q areas of section so that scalable to scrape when hydraulic cylinder push rod moves a small distance
Bar moves larger segment distance, makes modification scope bigger.
Preferably, the area of section of cavity P61 is 2 to 3 times of area of section of cavity Q81.
Preferably, replaceable convex block lower end forms connection bump, forms connecting groove on windscreen wiper base, connection bump with
Connecting groove is interference fitted.
The utility model has the advantage of：
(1) using projection cube structure, by the position waved to control scalable floating rule of wiper in itself, without motor list
Solely control, simple in structure, reliability is high, and manufacture is at low cost.
(2) projection cube structure replaceable is set, therefore can replace convex block of different shapes according to different vehicle window shapes to fit
Answer different demands.
