Beneficial effect
1st, under the driving of power set, by left screw rod and the synchronous rotary of right screw rod, make to move to left motion block and move right
Block synchronously moves downward or upward, so as to promote push rod and strut, the strut synchronous for being located at sunshading board both sides is opened or is collapsed,
So as to drive sunshade to open or collapse;
2nd, user only needs button, it becomes possible to sunshade is opened or is collapsed on demand, so that courtyard is by sunshade lid
Firmly or open wide.
Embodiment
As shown in Fig. 1 to Fig. 6, a kind of sunshade, used on the courtyard wall of square, mainly by polylith sunshading board 1,
2, two parallel guide rails 3 of strut, 4, cross bars 5 of two root posts, multiple coasters 6 and the power dress of more head and the tail axles even
Put 7 compositions.Power set are connected with a controller, and controller controls the switch of power set.
Described sunshading board uses frame structure, and every piece of sunshading board is surrounded by framework, and sunshading board is kept by framework
Stiffness, prevent because there is buckling phenomenon when longer hanging.If the span of sunshading board is too big, can also add in framework
Fill reinforcement.
Two described closed slides are separately fixed on the relative wall in two, courtyard, by setting between adjacent sunshading board
Hinge on sunshade plate framework is hinged, and can be folded.
A strut axis hole 21 is provided with the center of each strut 2, a screening is provided with the middle side edge of every piece of sunshading board
Positive board shaft hole, every strut are connected with corresponding sunshading board by strut axis hole and visor shaft hole axle;Described strut is in sunshade
Plate both sides symmetry arrangement.
When sunshading board opens, sunshading board forms the angle of an acute angle with adjacent strut, and the upper end of strut is higher than screening
Positive plate.The length of strut is more than the side edge length of the sunshading board with its axle even, when sunshading board opens in horizontal state completely
When, strut still has certain angle with horizontal plane, and when needing to deploy or collapsing sunshading board, this angle plays guiding
Effect.
Guide rail 3 is provided with coaster 6, and coaster is placed on guide rail by the pulley 61 matched with guide rail 3, two adjacent supports
The bottom of bar is connected on a coaster 6 by a fixing axle axle.
Described two root posts 4 are vertical with guide rail, and the bottom of each column is placed in the first coaster 62 on a guide rail
On, the both ends of cross bar 5 are separately fixed at the top of two root posts.I.e. two root posts are respectively disposed on two guide rails parallel to each other
On the first coaster on, cross bar is placed in the top of two root posts, forms four square frames of a lower opening.When column is in guide rail
On when sliding, cross bar can be driven also to be displaced outwardly.
Described power set 7 mainly include motor and planetary transmission, described planetary transmission it is defeated
Shaft is connected with power gear.The right side of described power gear sets a right driven pulley 8 engaged, and left side sets one
The individual left driven pulley 9 engaged.
Right line shaft 81 and left line shaft 91 are fixed on cross bar 5 by top chock;One end of right line shaft 81 and the right side
Driven pulley 8 is connected, and the other end is connected with right driving wheel 82, and right driving wheel 82 engages with right drive 83, and right drive 83 is located at
The top of right screw rod 84, right screw rod 84 are fixed on the inside of column by right axle bearing 85, are provided with right screw rod and are moved to right motion block 86,
The outer wall of right screw rod 84 is provided with screw thread, and described moves to right the internal thread for being provided with motion block 86 and being matched with right screw rod;Make to move to right motion block
It can be moved up and down when right screw rod rotates.
Accordingly, one end of left line shaft is connected with left driven pulley, and the other end is connected with left driving wheel, left driving wheel and a left side
Drive engages, and Left Drive wheel is located at the top of left screw rod, and left screw rod is fixed on the inside of column by left shaft holder, in left screw rod
It is provided with and moves to left motion block, the outer wall of left screw rod is provided with screw thread, and described moves to left the internal thread for being provided with motion block and being matched with left screw rod;
Enable to move to left motion block and moved up and down when left screw rod rotates.
Described left screw rod is full symmetric with right screw rod and screw thread is identical;Motion block is moved to left symmetrically to connect provided with two
Ear, move to right motion block and be provided with two symmetrical lugs;Catch bar 22 is provided between the wall and column vertical with guide rail, is promoted
One end of bar is fixed on by fixed seat 23 on the wall vertical with guide rail, and the other end on the inside of column by moving to left motion block
Or the lug moved to right on motion block is hinged on and moves to left motion block or move to right on motion block, the upper articulation of the initiating terminal of strut 2 is moving left
Block is moved to right on another lug on motion block, and other adjacent strut ends are hinged by axis hole and axle;It is fixed on fixed seat
On catch bar one end position less than promote-side the other end position.
As shown in Figure 7, it is necessary to when opening sunshade, power set power transmission is given, power set drive the positive rotation of power gear
Turn, power gear drives right driven pulley 8 and left driven pulley 9 to reversely rotate, and right driven pulley drives right line shaft 81 and right driving wheel
82 reversely rotate, and right driving wheel drives right drive 83 and right screw rod 84 to rotate forward, and the screw rod of rotation, which promotes, moves to right motion block 86
Move down;Meanwhile power gear drives left driven pulley 9 to reversely rotate, left driven pulley drives left line shaft 91 and left driving wheel
Reversely rotate, left driving wheel drives Left Drive wheel and left screw rod to rotate forward, and the screw rod promotion of rotation moves to left motion block and moved down.
Move to right motion block and move to left motion block and synchronously move down, and promote the catch bar 22 being attached thereto past for axle center with fixed seat 23 respectively
Under move in a circle, for catch bar during motion, column produces horizontal thrust, in the presence of the thrust, column 4
The coaster of lower section is displaced outwardly along guide rail.Strut 2 is outwards stretched out simultaneously, and strut band fly block and sunshading board are synchronously stretched along guide rail
Open, until stretching, extension is in place, motor is stopped.
As shown in figure 8, when collapsing, motor reversely rotates, and reversely rotates left screw rod and right screw rod, so as to drive catch bar
Collapsed with strut, strut drives sunshading board to collapse again, until collapsing in place, motor is stopped.
Drive sunshade to open or collapse using a motor, avoid the equilibrium problem of the lateral movement of sunshade two.Make
Both sides stress equalization, speed are consistent when sunshade opens or collapsed.
Described catch bar and strut are in the same plane, and its projection is overlapping with the projection of guide rail.
The lug with guide rail parallel is provided with addition to the coaster close to catch bar, at the top of remaining coaster;Connect with pulley axle
Strut connects with the lug axle at the top of coaster.
Described sunshading board uses glass or acrylic.
The top of right screw rod is connected through the bottom wall of cross bar with right drive;The top of left screw rod through cross bar bottom wall with
Left Drive wheel is connected.
Sunshade is loaded onto in rectangle courtyard, under the driving of power set, by left screw rod and the synchronous rotary of right screw rod, is made
Move to left motion block and move to right motion block and synchronously move downward or upward, so as to promote push rod and strut, make the support for being located at sunshading board both sides
Bar synchronously opens or collapsed, so as to drive sunshade to open or collapse.
When running into sleety weather or needing sunshade, user only needs to press the on & off switch on controller, it becomes possible to makes screening
Yang Peng opens, so that courtyard is covered by sunshade, waits after the sun shines again after the rain, or the sun sets, can press on & off switch again, make screening
Yang Peng is collapsed.
