Lower end by bearing be rotatably sheathed on winding side lever 61 upper end, and bow upper end by bearing with
The mode that can be rotated is sheathed on the end of winding push rod 62.It is arranged on bow by bearing for convenience of roller 631, arc
Bar can by some sections of straight-bars be sequentially formed by connecting like arc-shaped, a roller 631 is arranged on every section of straight-bar.Such as Fig. 4 institutes
Show, the two ends of roller 631 are each provided with roller teeth portion, this several roller 631 is nibbled along bow by roller teeth portion head and the tail
Conjunction links together, so as to arc-shaped transmission is integrally formed.And the roller 631 positioned at bottom connects with the upper end of winding side lever 61
Connect, the roller 631 positioned at the top is connected with the end of winding push rod 62.When winding side lever 61 is rotated, just can pass through
The transmission of roller 631 is rotated winding push rod 62, with simultaneously realize two sides of waterproof cloth and top surface are discharged or
Reclaim.
As shown in figure 1, the lower end of two mobile bars 7 is provided with mobile bar teeth portion, two lower ends of mobile bar 7 are respectively by moving
Lever teeth portion is engaged with the upper teeth portion of a driving belt 2 and is connected, so as to be carried out by the drive of driving belt 2 mobile bar 7
It is movable.Stretcher 8 is taken the shape of the letter U shape, and two rear ends of side of waterproof cloth are respectively arranged on a side lever for stretcher 8, and rain
The rear end of the top surface of cloth is arranged on the push rod of stretcher 8.Two side levers of stretcher 8 are respectively connected with a mobile bar 7, so that
The entirety of stretcher 8 is driven to be moved forward and backward by mobile bar 7.While stretcher 8 is moved rearwards by with away from rolling frame 6,
Rolling frame 6 discharges waterproof cloth, and waterproof cloth can just be covered on compartment, just can automatically carry out the laying of waterproof cloth；When stretcher 8 is to reach
Move to make while nearly rolling frame 6, the winding waterproof cloth of rolling frame 6 just can automatically carry out the recovery of waterproof cloth.
Preferably, as shown in fig. 7, the tooth of the mobile bar teeth portion of the upper teeth portion of driving belt 2 and mobile bar 7 is right angle ladder
Shape tooth, when driving belt 2 drives mobile bar 7 to be moved rearwards by, the straight flange of the straight flange of the tooth of upper teeth portion and the tooth of mobile bar teeth portion
Laminating, conversely, then for hypotenuse is fitted.Mobile bar 7 is to connect the Telescopic rod structure for constituting by spline engagement by two poles, and
A spring is folded between two poles of mobile bar 7, the pole of lower section can be moved up and down.It is further preferred that such as
Shown in Fig. 5 and Fig. 6, the winding side lever 61 of rolling frame 6 includes lower beam 611 and upper boom 612, the lower end of lower beam 611 and driving cog
Wheel 12 is connected, and the upper end of lower beam 611 is provided with lower beam teeth portion, and the tooth of lower beam teeth portion is right-angled trapezium tooth.The upper end of upper boom 612
It is connected with arc connector 63, the side volume of waterproof cloth is on upper boom 612.The lower end of upper boom 612 is provided with upper boom teeth portion, upper boom
The tooth of teeth portion is right-angled trapezium tooth.And upper boom 612 is to connect the Telescopic rod structure for constituting by spline engagement by two poles, and
Be folded with spring between two poles of upper boom 612, the pole of lower section can drive the pole of top to be rotated, and lower section section
Bar can be moved up and down.When driving belt 2 drives mobile bar 7 to be moved rearwards by, hypotenuse and the lower beam tooth of the tooth of upper boom teeth portion
The hypotenuse of the tooth in portion is relative, and both hypotenuses is fit together under the action of the spring, otherwise then for straight flange is fitted.Due to
When waterproof cloth is wound, waterproof cloth has certain flexibility to rolling frame 6, and waterproof cloth is rolled on two winding side levers 61 and winding push rod 62
The diameter for coming is not fully identical, therefore when discharging waterproof cloth or reclaiming waterproof cloth, the elasticity of the waterproof cloth of two sides and top surface will
Occur different, it is necessary to two winding side levers 61 and two speed of mobile bar 7 coordinate to make two sides of waterproof cloth and top surface
Keep tensioning state.When laying waterproof cloth is opened, driving belt 2 drives two mobile bars 7 to be moved rearwards by, now mobile bar 7
The tooth of the tooth of mobile bar teeth portion and the upper teeth portion 22 of driving belt 2 is fitted for straight flange, and two upper boom teeth portion of winding side lever 61
The hypotenuse of tooth fitted with the hypotenuse of the tooth of lower beam teeth portion.Mobile bar 7 is in vertical state, and two driving belts 2 just drive two
Mobile bar 7 is synchronous to be at the uniform velocity moved rearwards by.The upper boom teeth portion for winding the upper boom 612 of side lever 61 can be along under lower beam 611
Bar teeth portion is moved up and down, when waterproof cloth it is taut tension when, upper boom 612 is constantly upper to be moved, and eventually jumps out of lower beam 611, in rain
Side lever 61 and the winding quick release waterproof cloth of push rod 62 are wound in the presence of cloth, waterproof cloth is kept suitable rate of tension, finally in bullet
In the presence of spring, upper boom 612 still further below with lower beam 611 engage again by movement.
When recovery waterproof cloth is carried out, driving belt 2 drives two mobile bars 7 to move forward, now the mobile bar of mobile bar 7
The tooth of the tooth of teeth portion and the upper teeth portion 22 of driving belt 2 is fitted for hypotenuse, and two teeth of the upper boom teeth portion of winding side lever 61 with
The tooth of lower beam teeth portion is fitted for straight flange, and two winding side levers 61 and winding push rod 62 remain a constant speed rotation with synchronous winding raincoat.
The mobile bar teeth portion of mobile bar 7 can be moved up and down along the upper teeth portion 22 of driving belt 2, when waterproof cloth it is taut tension when,
Mobile bar 7 first jumps out of teeth portion 22, and then mobile bar 7 drives stretcher 8 quickly to move forward in the presence of waterproof cloth, keeps waterproof cloth
Suitable rate of tension, finally the mobile bar teeth portion of mobile bar 7 is moved down and engaged with upper teeth portion 22 again under the action of the spring.
Further, the shutter frame 9 of shape as shown in figure 1, waterproof cloth radio and tape player in compartment of the invention also takes the shape of the letter U including, hides
The lower end of two side levers of door frame 9 is articulated with two tops of side lever of stretcher 8, and is set between shutter frame 9 and stretcher 8
There is a shutter cloth (figure is not regarded).After waterproof cloth is laid, shutter frame 9 is opened backward, so that shutter cloth is covered in compartment
The top of door, prevents rainwater to be spilled into from car door, to improve efficiency of keeping off the rain.When waterproof cloth is wound, then shutter frame 9 is folded into exhibition
In open-shelf 8, to save space.
The present invention drives the winding side lever 61 and winding push rod 62 of rolling frame 6 to be rotated by driving belt 2, and simultaneously
Mobile bar 7 is driven to drive stretcher 8 to move, so as to realize opening laying or recovery to compartment waterproof cloth, it can be saved
Labour, easy to use and high working efficiency.
The foregoing description to specific illustrative embodiment of the invention be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that certain principles of the invention and its reality should
With so that those skilled in the art can realize and using a variety of exemplaries of the invention and
A variety of selections and change.The scope of the present invention is intended to be limited by claims and its equivalents.
