Description
Technical field
The present invention relates to Automobile Products field, more particularly to a kind of automobile mounted mobile projector curtain with sunshade function and throwing
Shadow system.
Background technology
With the improvement of living standards, automobile is increasingly popularized, requirement more and more higher of the people to configuration of automobiles, but at present
Entertainment systems on automobile are only equipped with navigation multimedia system on the dash panel, but are limited by screen size, and passenger can not relax
Video and audio are appreciated suitablely.
In addition, various automobiles automotive interior before dispatching from the factory does not have abat vent on Vehicles Collected from Market, some medium-to-high grade cars
Only there is abat vent on heel row or so window, during the broiling summer, after automobile parks a period of time under the sun, vehicle interior temperature meeting
Rapid rise, not only make one that the temperature of in-car can not be adapted to, into the car before the window that must first drive turn on the aircondition cooling, and can add
The aging of fast in-car each part, therefore Sunshade film is all sticked on many vehicle glasses, but for visual field demand, automobile front wind screen glass
Glass can not pad pasting, people generally cover front windshield with abat vent, remove again during driving.Current front windshield
Abat vent, it is mostly left and right pull type, this mode can not be preferably bonded with windshield, and due to from left-hand
The extension elongation that back sunshade cloth is pulled open on the right side is larger, and the edge curl of cord is easily made in winding, causes the winding of cord not
It is smooth, easily it is stuck, the hand-held abat vent lower beam of whole process is needed so as to cause to project the damage of curtain, and during cord recovery parallel time
Receive., not so will be because of elasticity certainly and existing abat vent pulls out end and have to last for hand-held and be fixed in time after pull-out
Dynamic to withdraw, in addition, existing abat vent is fixed on front windshield using vacuum cup, this fixed form is insecure,
The sun has shone long or will come off when running into small jolt, and influences using effect and traffic safety, is carried out on the spot when can only be and use
Fixed operation, it is not appropriate for being suspended on the top of front windshield for a long time.
The content of the invention
It is an object of the invention to provide a kind of automobile mounted mobile projector curtain with sunshade function, the projection curtain is provided with resistance
From combining structure, projection cord can anywhere hover when pulling out, and pull out end without being fixed again, can be used not only for throwing
Shadow, the length according to corresponding to pulling out projected area size, makes passenger have more preferable recreation experience, and before can apply to automobile
The sunshade of windshield, in addition, when pressing resistance dissociation locking device, projection cord can be in wrap-up, isolator and unidirectional friction
Evenly automatically retracted in the presence of component, convenient degree is high, service life length.
What the present invention was realized in：
Scheme (one)：
A kind of automobile mounted mobile projector curtain with sunshade function, it is characterised in that：Including fixed outer tube, coaxially it is fixedly arranged on
Projection cord that axis in fixed outer tube, the roller shutter pipe for being movably set in axis periphery, one end are wound on roller shutter pipe, set

The wrap-up 9 of withdrawal, be arranged between roller shutter pipe 7 and fixed outer tube 5 be used to realize when projecting cord 8 and automatically retracting it is single
To the isolator 10 at the uniform velocity acted on, it is arranged at being hovered for enabling projection cord 8 to pull out between roller shutter pipe 7 and fixed outer tube 5
Resistance from combining structure 11 and be arranged at fixed outer tube 5 and hinder between combining structure 11 to be used to release projection cord 8 single
Dissociate locking device 12 to the resistance for pulling out limitation, the isolator 10 include being fixedly connected on unidirectional outer tube 101 on roller shutter pipe 7,
The unidirectional inner tube 102 and be connected between unidirectional outer tube 101 and unidirectional inner tube 102 that coaxial sleeve is located in unidirectional outer tube 101
Unidirectional spring 103, the unidirectional spring 103 are movably set on the periphery wall of unidirectional inner tube 102, the unidirectional spring 103
One end is connected with unidirectional outer tube 101 so that unidirectional spring 103 and unidirectional outer tube 101 are relatively unrotatable, the unidirectional spring
The rotation direction of roller shutter pipe 7 is identical so that unidirectionally outer when projection cord 8 is withdrawn when 103 hand of spiral is withdrawn with projection cord 8
Pipe 101 can drive unidirectional inner tube 102 to rotate by unidirectional spring 103, and the projection curtain also includes being connected to the unidirectional He of inner tube 102
The unidirectional friction component 13 for being used to produce frictional resistance when projecting cord 8 and withdrawing between fixed outer tube 5.In the present embodiment
In, one end of unidirectional spring 103 is provided with bending bar 105, and the outer wall of isolator outer tube 101 is in axial direction provided with spring low water
106, bending bar 105 is located in spring low water 106, and when projection curtain is withdrawn, spring low water 106 drives bending bar 105 unidirectional along bullet
The hand of spiral rotation of spring 103 so that the inner periphery footpath of unidirectional spring 103 diminishes, so as to hold the unidirectional periphery wall of inner tube 102 tightly,
Realize that unidirectional outer tube 101 can drive unidirectional inner tube 102 to rotate by unidirectional spring 103, when projection curtain pulls down, spring low water 106
Spiral opposite direction of the bending bar 105 along unidirectional spring 103 is driven to rotate, top unfolds knee 105 and causes the inner periphery of unidirectional spring 103
Footpath becomes big, unidirectional spring 103 is released in the unidirectional periphery wall of inner tube 102, so as to realize unidirectional effect.In the present embodiment,
Wrap-up 9 uses torque spring.
As shown in Fig. 1, Fig. 4-Fig. 7, in order to make projection cord produce frictional resistance when withdrawing, at the uniform velocity received so as to realize
Return, the fixed outer tube 5, which is located on the end face of the one end of isolator 10, is installed with left end cap 51, and the unidirectional friction component 13 includes
