The present invention proposes a kind of wiper for being conducive to pedestrian head protection, improves performance of the automobile in terms of pedestrains safety is protected.Connection pumping, drive shaft and the driving motor with driving axis connection that the wiper includes wiper arm, is connected with wiper arm；Key is that the connecting shaft is connected with drive shaft by crushable structures.Above-mentioned wiper possesses the basic function of traditional wiper blade structure：It is i.e. daily in use, when there is no pedestrian impact, do not influence windscreen wiper correlation intensity and function.When vehicle meets pedestrian, during pedestrian impact windscreen wiper axis near zone, if the axial force of windscreen wiper axis is more than design load, crushable structures will be by conquassation, so that connecting shaft and wiper arm move down, so as to increase the conquassation space during head impact, caused injury in impact is reduced, and lifts the score in C-NCAP experiments.The present invention is ingenious in design, on the premise of normal function is not influenced, adds the function of pedestrian protecting, has good practicality.
Description
Technical field
The invention belongs to automotive field, and in particular to a kind of wiper for being conducive to pedestrian head protection.
Background technology
Widely available with China's home vehicle, road pedestrian safety problem increasingly highlights.Global road in 2015
In the traffic accident of road, Road Traffic Accidents in China pedestrian's death rate whole world highest, is 30%.In pedestrian and the thing of collision of motor-driven vehicles
In therefore, pedestrian is often disadvantaged group, and protection pedestrian becomes the pith of major main engine plants' security development.Start within 2002,
Pedestrian protecting formally becomes one of Euro NCAP new car appraisement system evaluation contents, in 2018 editions C-NCAP of newest announcement,
Pedestrian protecting is formally introduced into the considering among index of C-NCAP.
In 2018 editions C-NCAP pedestrian heads protection ranking methods, by simulating the pedestrian of different heights, so as to mark off
Head region of being grown up and children's head region, and simulated crash, root are carried out using different head model and different angle in respective regions
According to head injury value height, corresponding pedestrian protecting head score is drawn.Wherein since wiper arm rigidity is bigger, and touched from head
It is closer to the distance to hit contact point, therefore nearby head injury value is higher for wiper arm, C-NCAP scoring rates are relatively low.
The content of the invention
The purpose of the present invention is to propose to a kind of wiper for being conducive to pedestrian head protection, improves automobile in protection pedestrian
The performance of secure context.
The present invention be conducive to pedestrian head protection wiper include wiper arm, be connected with wiper arm connection pumping,
Drive shaft and the driving motor with driving axis connection；Key is that the connecting shaft is connected with drive shaft by crushable structures.
Above-mentioned wiper possesses the basic function of traditional wiper blade structure：It is i.e. daily in use, when there is no pedestrian impact, no
Influence windscreen wiper correlation intensity and function.When vehicle meets pedestrian, during pedestrian impact windscreen wiper axis near zone, if the axis of windscreen wiper axis
It is more than design load to active force, crushable structures will be by conquassation so that connecting shaft and wiper arm move down, so as to increase head
Conquassation space in portion's impact process, reduces caused injury in impact, and lifts the score in C-NCAP experiments.
Specifically, the connection take out, drive shaft for opening is opposite and two sleeves of nested encryptions, one of sleeve
Sleeve wall be equipped with through hole, the sleeve wall of another sleeve is equipped with elastic arm, and the end of the elastic arm is stretched in through hole.On
Power transmission can usually played the role of by stating elastic arm, and the rotation of drive shaft is delivered to connection draws up, so as to drive rain
Scraping arm scrapes water, and when pedestrian impact occurs, elastic arm under the pressure effect of connecting shaft, from through hole deviate from by its end, makes
Obtaining can relatively move between connecting shaft and drive shaft, realize crumple function.
Further, deviate from for convenience out of through hole, the end of the elastic arm is coniform or hemispherical configuration, is had
Good guide function.
Further, to ensure the function of power transmission, the through hole has sleeve walls that are multiple, and being uniformly distributed in sleeve
On.
Further, to prevent into water, the connection is taken out, drive shaft is cased with rubber protecting jacket.
Further, the connection takes out, is provided with spring between drive shaft, in design, ensures connecting shaft and drive shaft
During normal assembling, spring is free state, and so the spring can provide certain support force, and when pedestrian impact occurs,
Spring does not interfere with crumple function again, moreover, spring can also play certain cushioning effect upon compression.
Further, to ensure the function of power transmission, the sleeve wall of described two sleeves is equipped with intermeshing bar shaped
Tooth, the extending direction of the bar shaped tooth are the direction of sleeve axis, and intermeshing bar shaped tooth forms the function of gear, to protect
Card connection is taken out, is rotated synchronously between drive shaft.
The wiper for being conducive to pedestrian head protection of the present invention is ingenious in design, is not influencing the premise of normal function
Under, the function of pedestrian protecting is added, there is good practicality.

Embodiment
Below against attached drawing, by the description to embodiment, for example involved to the embodiment of the present invention is each
Mutual alignment and connection relation, the effect of each several part and operation principle between the shape of component, construction, each several part etc. are made into one
The detailed description of step.
Embodiment 1：
As shown in the figure, the wiper for being conducive to pedestrian head protection of the present embodiment includes wiper arm 1, is connected with wiper arm 1
Connection take out 2, drive shaft 3 and the driving motor 4 being connected with drive shaft 3；It is that opening is opposite and nesting connects to connect and take out 2, drive shaft 3
Two sleeves connect, the wherein sleeve wall of drive shaft 3 are equipped with through hole 31, and the sleeve wall of connecting shaft 2 is equipped with elastic arm 21, the bullet
The end 22 of property arm 21 is stretched in through hole 31.The parting line of upper and lower two sleeves is located at water proof rubber 5, does not influence waterproof
Function and moulding.
Above-mentioned wiper possesses the basic function of traditional wiper blade structure：It is i.e. daily in use, when there is no pedestrian impact, no
Influence windscreen wiper correlation intensity and function, elastic arm 21 play the role of power transmission, the rotation of drive shaft 3 is delivered to connection takes out
On 2, so as to drive wiper arm 1 to scrape water.When vehicle meets pedestrian, during pedestrian impact windscreen wiper axis near zone, if windscreen wiper axis
Axial force is more than design load, and elastic arm 21 under the pressure effect of connecting shaft 2, at through hole 31 deviate from, and makes by its end 22
Obtaining can relatively move between connecting shaft 2 and drive shaft 3, and connecting shaft 2 and wiper arm 1 move down, so as to increase head impact
During conquassation space, reduce impact in caused injury, and lifted C-NCAP experiment in score.
In the present embodiment, the end 22 of elastic arm 21 is the coniform injection pin being installed on elastic arm 21, is being pressed
, only need to be by pressure injection pin in routed follow-up maintenance process, you can replace windscreen wiper upper bush, reduce maintenance cost.The pressure of windscreen wiper axis
Routed power can be according to injection pin intensity adjustment, to balance pedestrian protecting and windscreen wiper strength relationship.
