Description
Technical field
The utility model is related to field of vehicle equipment, in particular to a kind of wiper.
Background technology
Wiper, that is, wiper refers to the slice structure before the windshield of automobile.Wiper is for striking off
The equipment of the sundries in vehicle windscreen is attached to, to improve the visibility of driver, increases traffic safety.Existing windscreen wiper
Device needs driver to manually boot, and can not adjust rain shaving blade velocity of rotation, it is impossible to cope with invading for different degrees of rainwater well
It attacks, while windscreen wiper leaf length is shorter, cleaning area is smaller, and subregion cleaning may be caused unclean, influence pilot's line of vision.
Utility model content
The technical problem to be solved by the utility model is in view of the deficiencies of the prior art, provide a kind of cleaning area
Greatly, can start automatically, the higher wiper of heavy rain day working efficiency.
In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of wiper, including wiper arm and rain shaving blade, it is characterised in that：The wiper arm includes the first wiper arm and the
Two wiper arms, first wiper arm are hinged with the second wiper arm, and the rain shaving blade includes fixed rain shaving blade and slides windscreen wiper
Piece, the fixed rain shaving blade are slidably connected with sliding rain shaving blade by an attachment device, described fixed rain shaving blade one end and the
The second end of one wiper arm is hinged, and the fixed rain shaving blade is articulated with the other end of first wiper arm one end with sliding rain shaving blade phase
Even, the second wiper arm second end, which is articulated with, slides in the middle part of rain shaving blade, and the slip rain shaving blade can slide along fixed rain shaving blade,
First wiper arm is articulated with windscreen wiper arm arbor with fixed rain shaving blade, and the windscreen wiper arm arbor passes through retarder and engine phase
Even, the engine is connected with the piezoresistive pressure sensor that can be sensed and bear pressure, and the piezoresistive pressure sensor, which is fixed, to be connected
It is connected to baffle surface.
By using said program, two wiper arms are hinged at their first end, the second end difference of two wiper arms
It is connected in fixed rain shaving blade and slides rain shaving blade, fixed rain shaving blade is slidably connected with sliding rain shaving blade, in use, driving force is transmitted to
First wiper arm, the first wiper arm drive the rotation of the second wiper arm, and the second wiper arm, which drives, slides rain shaving blade so as to increase windscreen wiper
Leaf length expands wiper cleaning area.
Further, the attachment device include being set on the sliding slot of fixed rain shaving blade, set on the groove for sliding rain shaving blade and
One bolt for passing through sliding slot and groove.
Further, the bolt passes through sliding slot with groove and even there are one nuts in fixed rain shaving blade surface.
By using said program, bolt, which passes through sliding slot and groove and combined with nut, is fixed at sliding slot side, slides
Rain shaving blade can be slided along sliding slot until sliding into bolt location.
Further, the piezoresistive pressure sensor by one pass through deflector conducting wire along automotive interior with starting
Machine is connected.
Using the above scheme so that conducting wire discord contacting rain water ensures the safety of vehicle.
Further, the piezoresistive pressure sensor includes pressure-sensing device and signal processing unit.
Using the above scheme, piezoresistive pressure sensor measures pressure by pressure-sensing device, when rainwater is to pressure
When the pressure of resistance pressure sensing element reaches certain value, signal is delivered to signal processing unit, pressure by pressure-sensing device
Processing unit exports engine so that wiper starts operation.
Further, the difference for the pressure that the piezoresistive pressure sensor is born according to pressure-sensing device, at signal
It is also different to manage unit output frequency.
Using the above scheme, different, the signal processing lists also different to the pressure of piezoresistive pressure sensor of rain size
The output power of member also accordingly changes, and when the force of rain is larger, piezoresistive pressure sensor is also larger to the output power of engine,
So that dynamic frequency is scraped in wiper acceleration, without adjusting wiper frequency manually, driving sight of the driver in the big rainy day ensure that
With the focus of driving, driving safety ensure that.
The beneficial effects of the utility model are：It solves the problems, such as that wiper cleaning area is insufficient, ensure that glass baffle plate
Cleaning, solve the problems, such as wiper cannot automatically start in the rainy day, cannot according to rain size adjust windscreen wiper frequency, ensure
The driving sight of driver, comfortable driving environment is but also drive safer.

Specific embodiment
For that can further appreciate that the contents, features and effects of the utility model, embodiment is listed below, and coordinate attached drawing detailed
Carefully it is described as follows.
A kind of wiper, including wiper arm and rain shaving blade, wherein, wiper arm includes the first wiper arm 11 and the second wiper arm
12, the first wiper arm 11 is hinged with the second wiper arm 12, specifically, the first wiper arm 11 can pass through with the second wiper arm 12
Bolt 13 forms hinged relationship as hinge.
Further, rain shaving blade includes fixed rain shaving blade 21 and slides rain shaving blade 22, and fixed rain shaving blade 21 is with sliding windscreen wiper
Piece 22 is slidably connected, specifically, fixed 21 one end of rain shaving blade and the second end of the first wiper arm 11 are hinged, fixed rain shaving blade 21 is another
One end is connected with sliding rain shaving blade 22, and 12 second end of the second wiper arm, which is articulated with, slides 22 middle part of rain shaving blade.
Further, fixed rain shaving blade 21 is connect with sliding rain shaving blade 22 by an attachment device, and attachment device includes
Sliding slot 31 set on fixed rain shaving blade, groove 32 and a bolt for passing through sliding slot 31 and groove 32 set on slip rain shaving blade 22
33, bolt 33 passes through sliding slot 31 with groove 32 and even there are one nuts 34 in fixed 21 surface of rain shaving blade.Concrete operating principle is：
During work, the first wiper arm of drive force 11 is influenced close to fixed rain shaving blade 21, the second wiper arm 12 by the first wiper arm 11
Linkage effect occurs, increases rain shaving blade area so as to drive to slide rain shaving blade 22 and slide along sliding slot 31.
Further, the first wiper arm 11 is articulated with windscreen wiper arm arbor 4 with fixed rain shaving blade 21, and windscreen wiper arm arbor 4 passes through
Retarder is connected with engine, and even there are one piezoresistive pressure sensor, piezoresistive pressure sensor is fixedly connected on engine
The surface of deflector, and pass through a conducting wire and connect along automotive interior with engine, it is quick that piezoresistive pressure sensor includes pressure
Sensing unit and signal processing unit, piezoresistive pressure sensor can drive engine start wiper to work, and can be according to not
Rain shaving blade velocity of rotation is adjusted with the force of rain.Concrete operating principle is：When raining, rainwater falls on piezoresistive pressure sensor and generates
Pressure, pressure-sensing device can sense the pressure that windshield is subject to, and when pressure reaches certain value, pressure-sensing device will be believed
Number signal processing unit is sent to, signal processing unit is exported again to engine, and wiper is allowed to start operation, big according to what is rained
Small, pressure that sensor is subject to is different, when rain is very big, relatively low windscreen wiper underspeed to remove the flow on windshield, this
Device can accelerate rain shaving blade slewing rate when rain is very big, ensure that the driving sight of driver.
The thing finally illustrated：It is the preferred embodiment that embodiment is only the utility model above, rather than its limitations；Although
