Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that the present invention is protected
The limitation of scope.
The present invention proposes a kind of frontal windshield rain brush pretightning force dynamic adjustment mechanism, by the way that rain brush brush arm is arranged to pair
Claim air foil shape, and by dynamic adjustment mechanism, rain brush thrust dynamic is maintained at the thrust design threshold of ground adjustment
It is interior, avoid the phenomenon for departing from windshield surface occur during windscreen wiper use.
Fig. 1 gives the sectional view of rain brush, and with reference to figure 1, the direction from brush arm 1 to adjustment face 2 is the width of rain brush brush arm
Direction, windscreen wiper arm lengths direction are perpendicular to the plane where Fig. 1.
Rain brush brush arm width of the present invention is arranged to symmetrical airfoil shape, i.e. brush arm 1 is with adjusting the composition of face 2 in Fig. 1
The front and rear edge structure similar to wing is shaped as, the front end (left side in Fig. 1) of brush arm 1 is windward side, itself and wing windward side one
Sample sets camber, and the adjustment face that the rear end of brush arm 1 is hinged is arranged to tip as wing leeward side.
Referring again to Fig. 1, frontal windshield rain brush pretightning force dynamic adjustment mechanism of the present invention, mainly include brush arm 1, adjustment face
2nd, spring 5, the first sliding block 6 and transmission rod 8, brush arm 1 connect the sliding block 6 by spring 5, and the sliding block 6 can fly described
Slided on the covering of machine, the front end of the brush arm 1 is windward side, and rear end is rotatablely connected by rotating shaft 3 and the adjustment face 2, institute
The adjustment face of stating 2 is hinged the transmission rod 8 in one end of connection brush arm 1, and the other end of the transmission rod 8 is hinged first sliding block
6, when the brush arm 1 and the adjustment face 2 are without angle (hereinafter referred to as described adjustment face is in neutral position), the spring 5 has
Preload pressure.
In the present embodiment, for preferably the first sliding block, spring and brush arm are connected, in addition to adjusting screw 9 and sleeve 4,
First sliding block 6 and it is arranged at the spring 5 that the first sliding block 6 is connected in the sleeve 4, the other end connection of the spring
Second sliding block 10, second sliding block 10 can be slided in the sleeve, and through hole, the through hole are provided with the brush arm 1
Including the larger Part I of internal diameter and the less Part II of internal diameter, the Part II is screwed hole, the adjustment spiral shell
Nail 9 is screwed into the Part II of through hole from the Part I of the through hole, and apical grafting deviates from the bullet to second sliding block 10
One end of spring 5.
In the present embodiment, being slided away from one end of the spring 5 by roller bearing 7 for first sliding block 6 is adjacent in aircraft
On covering.
When aircraft is in the state of ground, after the pretightning force of frontal windshield rain brush brush arm 1 is adjusted into design threshold, pass through adjustment
Adjusting screw 9 makes adjustment face 2 be in neutral position；After taking off, if nearby aerodynamic force caused by air-flow makes brush to plane nose
Arm 1 is away from skin-surface (or windshield surface) on the downside of frontal windshield rain brush brush arm, and now spring 5 transmits natural resiliency power
To sliding block 6, roller bearing 7 is remained intact with skin-surface (or windshield surface) on the downside of frontal windshield rain brush brush arm and contact；Together
When because brush arm 1 is away from skin-surface (or windshield surface) on the downside of frontal windshield rain brush brush arm, cause transmission rod 8 to produce one
It is individual to rotate counterclockwise adjustment face 2 around the moment of torsion of face rotating shaft 3 is adjusted, and then make the trailing edge of adjustment face 2 to away from frontal windshield windscreen wiper
The direction movement of skin-surface (or windshield surface) on the downside of arm, so that the brush arm 1 with symmetrical airfoil shape produces one
Individual downward lift, moves down brush arm 1, until adjustment face 2 is in neutral position；
Nearby if aerodynamic force caused by air-flow makes brush arm 1 close to skin-surface on the downside of frontal windshield rain brush brush arm to plane nose
(or windshield surface), now natural resiliency power is passed to sliding block 6 by spring 5, is made under roller bearing 7 and frontal windshield rain brush brush arm
Side skin surface (or windshield surface) remains intact contact；Simultaneously because brush arm 1 is close on the downside of frontal windshield rain brush brush arm
Skin-surface (or windshield surface), cause transmission rod 8 to produce one around the adjustment moment of torsion of face rotating shaft 3, make adjustment face 2 clockwise
Rotate, and then make the trailing edge of adjustment face 2 to the side close to skin-surface (or windshield surface) on the downside of frontal windshield rain brush brush arm
To movement, so that the brush arm 1 with symmetrical airfoil shape produces a upward lift, move up brush arm 1, until adjusting
Whole face 2 is in neutral position.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the essence of various embodiments of the present invention technical scheme
God and scope.
