2, the full projection screen of automobile and projection device, application number: CN201710968533.2, applicant: pole fish (north
Capital) Science and Technology Ltd.；Abstract: the present invention provides a kind of full projection screen of automobile and projection devices, are related to automobile projection
The technical field of equipment, including projection cloth and closing-folding mechanism；The closing-folding mechanism is described for packing up and being unfolded the projection cloth
Projection cloth be arranged in automobile by the closing-folding mechanism and conveniently sit in the back row passenger viewing region, solve existing skill
The function of projection screen in automobile present in art is excessively single, and the area of projection screen is too small, viewing either use feeling
It is poor, while the technical problem of the storage folding inconvenience of projection screen, reach of simple structure and strong practicability, can pass through
The effect of closing-folding mechanism is rapidly completed the folding to projection screen and greatly increases the technical effect of user experience.
Existing related data is shown: there are curtains, and out-of-flatness is unfolded for existing automobile-used projection and curtain equipment, and installation is tired
Difficulty, the scope of application is not wide, and storage is difficult, the excessive disadvantage of occupied space.
Summary of the invention
The utility model provides a kind of portable vehicle projection screen, suitable for carrying out consolidating for projection screen within the interior or exterior of the vehicle
It is fixed, it is projected on projection screen using LED projector, carries out video image evaluation, have drop shadow effect good, storage is efficient and convenient, fixed
Securely, and can angle-adjustable the advantages that.
The technical solution of the utility model is achieved in that
A hole is respectively arranged in a kind of portable vehicle projection screen, four angles of curtain, and 4 curtain cradling pieces are arc, end
In S curved shape, bending section passes through and is stuck on hole wall, and curtain cradling piece is manufactured using memory metal or elastoplastic, has
Excellent elasticity and restorable function, the other end of 4 curtain cradling pieces are fixedly linked with intermediate projection screen fixing head,
Fixing head back connects vacuum chuck, and vacuum chuck is adsorbable on the backsight glass of vehicle interior, and projector projects picture is real
The function of existing car viewing, sucker are also adsorbable in the function of on outside vehicle outer wall, realizing the outer viewing of vehicle.
The junction of the projection screen fixing head and curtain cradling piece is arranged cradling piece movable head, and cradling piece movable head can be around
Fixing head pedestal carries out 90 degree of rotations, and the bracket rod end on movable head rotates outwardly, so that it may prop up cradling piece, build projection screen
After removing curtain, the bracket rod end on movable head is rotated downward when needing to store projection screen for cloth, can be by four brackets
Bar closes at lower section, reduces the space occupied.
Elastic positioning pin is set on the cradling piece movable head, and elastic positioning pin is real by setting and the pressure spring below pin
Show elastic shrinkage, pin hole, bracket rod end court of the Elastip pin on movable head is arranged in working position matching position on fixing head pedestal
On the working position of outer rotation, Elastip pin matches insertion with pin hole, and cradling piece is secured firmly to working position and is not shifted；Work as storage
When cradling piece, user firmly pulls runing rest bar movable head, and Elastip pin stress is retracted pin hole, realizes storage function.
Multi-directional ball is set between the fixing head pedestal and vacuum chuck, and the shell of multi-directional ball is embedded in fixing head pedestal
In, screw rod and can be held out against radially across the ball of multi-directional ball with multi-directional ball shell interior side contacts；The shell and ball of multi-directional ball can
Any angle sliding rotation, the screw rod other end are fixedly installed knob, are used for rotary screw；The back end activity rotation connection of knob is true
Suction disk.It so just realizes projection screen and can arbitrarily adjust its tilt angle and orientation, convenient for users in different fixed points, no
With height, different perspectives is adjusted projection screen.
Hinge is set in the middle part of the curtain cradling piece, and cradling piece can be stored to front/rear bending；After cradling piece bending storage,
The volume for further reducing entire projection screen storage is more convenient to be packed into interior carry.
The curtain cradling piece is multilayer sleeve structure, and storage that casing is shrinkable or stretching, extension use, and cradling piece shrinks storage
Afterwards, the volume for further reducing entire projection screen storage is more convenient to be packed into interior carry.
Compared with prior art, the advantages of the utility model:
1, the utility model by cradling piece movable head and can storage support bar dual storage function, can be by projection screen body
Product is contracted to 1/tens using volume, and projection screen is packed into car, is convenient for carrying.
2, the expansion of the utility model projection screen is convenient, is not necessarily to tool, and stable structure is reliable, compares Scroll projection screen, curtain
Cloth is more smooth, and display effect is more preferable.
3, in the utility model multi-directional ball and bolt use, its tilt angle and side can arbitrarily be adjusted by realizing projection screen
Position, convenient for users in different fixed points, different height, different perspectives is adjusted projection screen, no matter outside interior vehicle, use
Person can realize viewing function.
