Abstract

The present invention provides a sunshade shading rolling blind which is provided with the tightened rolling blind and two guide tracks. Wherein, each guide track is operated with a drive element which is driven by an independent drive gear by using forward conjunction. In order to start the shading rolling blind by hand, the rotation movement of the rolling blind is transferred to the drive gear and is then transferred to the drive element by the gear. During the period of withdrawing the shading rolling blind, a force is acted on the rolling blind from the drive element by the drive gear in order to generate a necessary rotation motion of the rolling blind.

Description

Manually activated roll-up window shade

Technical field

The present invention relates to be used for the manually activated roll-up window shade of automobile.

Background technology

Usually, manually activated roll-up window shade is textural more simpler slightly than electronic activated roll-up window shade.Electronic activated roll-up window shade needs drive motor, and this has increased cost.If activated roll-up window shade is positioned at the effective range of driver, can easily use manually activated roll-up window shade so.The preferred activated roll-up window shade that can manually boot is a sunshade top activated roll-up window shade, and it needs to remain on any random centre position sometimes.

The simplest form of this activated roll-up window shade is used and is being rolled the spool of being partial in the direction of window-blind under the help of spring motor.Window-blind is connected on the manual draw bar that in side rails, is guided away from the there of spool.Should guarantee that at the check mechanism on the pull bar pull bar can remain on each desired locations and do not move in the spool direction under the effect at spring motor.For this purpose, owing to starting the terminal point in path, spring motor is by more intense pulling out, that is, and and for the window-blind that launches fully, even when use has the spring motor than the flat characteristic line, so that braking action must be designed to is more intense.

In addition, in this set, depend on whether window-blind is drawn out or withdrawal to a great extent, and the tensile stress in window-blind is significantly different.

The another one shortcoming is because the active force of the braking and the spring motor that will overcome, and the tripping force that will apply is upon deployment significantly when regaining.

Therefore, known in order to obtain more constant tripping force from DE 10 2,004 038 756 A1, cotton rope is attached to each end of pull bar, make that it extends to the far-end of guide rail from pull bar from the angle of spool.Backguy is in the revolution of the far-end of guide rail and extend back and turn back to spool.For each root backguy, provide with spool coaxial above be wound with the pulley of cable.Between pulley and spool, be provided with spring compression means, it is necessary when the length difference that window-blind is produced when unwinding launches from spool for compensation, and simultaneously at opposite side, backguy is wound up on the pulley with constant effective radius.

This setting is proved to be well-adapted, but it need use the backguy that is not easy to install.

Begin from this situation, problem of the present invention is to make the manually activated roll-up window shade that is used for automobile that needs low producing cost.

Summary of the invention

According to the present invention, utilizing hereinafter described, the manually activated roll-up window shade of characteristic solves this problem.

For the manually activated roll-up window shade of this novelty, a rotatably mounted spool is provided.One side of window-blind is fixed on the spool.The another side of window-blind is connected on the pull bar, and said pull bar is in the end is directed into two guide rails.Guide rail extends on the both sides of the window-blind of tension.

In order to keep window-blind to be in tension, two pushing members are provided, one of them is assigned to a guide rail and another is assigned to another guide rail.Pushing member is directed in the guide rail and all carries tooth.It interacts with mode and the pull bar that promotes.Each pull bar is configured to discontinuous starting element, so it has two ends not connected to one another.

The activated roll-up window shade of this novelty comprises two driven wheels in addition, and one of them is assigned to a pushing member and another is assigned to another pushing member.Driven wheel is arranged in the end of spool.Pushing member works between driven wheel and pull bar with moving.

Keep window-blind tension force by means of another machinery setting.

For this purpose, in principle, it is possible that two kinds of solution paths are arranged.At first, can form additional machinery setting through spring assembly or a kind of gear.

In one embodiment, work between spring assembly each gear in spool and two driven wheels.This is a kind of solution in space and structurally also fairly simple of especially saving.For this purpose, pull bar can be used for unsuitable operation in each end grappling.

Another connecting axle is provided in another program, and it is parallel to this spool extends, and gear is housed on it.[gear] also can tensionally elastic mode be connected to connecting axle, and this connecting axle is connected to spool in its side through gear.

Aspect interference, if two gears and connecting axle locking rotatably, these relations can become relatively good so, because so at the pushing member that moves through rigid connection each other at pull bar two ends and forward is sent to the other end.This is applicable to recovery movement.For launching motion, these relations are just so unimportant, because can fully guarantee just that through window-blind the forward between the pull bar two ends is synchronous.

If use above that locking rotatably that the additional shaft of driven wheel is arranged, so just can get rid of spring assembly as the additional mechanical measure.Like this, it is just enough to transmit or reverse the respective gears of the connecting axle that rotatablely moves of spool.

, cable hauling gear produces favourable relation when being used as gear, the effect that the coil diameter that utilizes this cable hauling gear can compensate the scroll that on spool, is formed by window-blind comparatively simply changes.Because it is constant that the diameter of gear keeps, under the situation of uncompensated cable hauling gear, it is constant that the displacement length of pushing member keeps, and along with the scroll diameter reduces, the amount of expansion of window-blind also reduces.

Cable hauling gear can comprise cylindrical pulley and worm screw.Worm screw comprises the truncated cone shape pulley with guide recess, and it guarantees cable placement in order on the cone scope.

Preferably use pushing member as pushing member with circular section, for example, by cylindrical core bar be attached to the pushing member that outside helical spring is formed.

Guide rail preferably can contain the guide recess of undercutting.Guide recess is made up of groove cavity and groove slit, and the A/F of groove slit is less than the diameter of groove cavity.This guarantees that the guiding of pushing member in groove cavity avoids buckling into.

Carry one in passing, in embodiment, also introduced improvement of the present invention.

Below glass roof 21, can see the window-blind 22 that part is launched.Window-blind 22 is fixed to pulls out on the configuration part 23.Window-blind 22 with pull out configuration part 23 and belong to manually activated roll-up window shade 24.

Fig. 2 has shown the essential structure of activated roll-up window shade 24.

According to Fig. 2, extend 25 side on sunshade top, and two

guide rails

26 and 27 belong to sunshade top activated roll-up window shade 25.

Guide rail 26 with 27 to become the mirror image symmetric arrays each other and to push up the profile of 25 sides and go along sunshade.

Because two guide rails 26 are identical with 27, so as long as the internal construction of explanation guide rail 27 is just enough.These explanations are applicable to guide rail 26 too.

In guide rail 27, be provided with undercutting guide recess 28, the section of undercutting guide recess 28 comprises groove cavity 29 and groove slit 30.The width of slit 30 is less than the A/F of groove cavity 29, and this has produced undercut construction.

Two

guide rails

26 and 27 be used to guide window-blind 22 one side attached pull bar 23.Pull bar 23 comprises the stage casing, wherein two extremity pieces 32 of telescopically guiding and 33.The stage casing is installed on (for example) on window-blind 22 in the formed hose-like ring.

Each extremity piece in two

extremity pieces

32 and 33 has an expansion link 34, and slide block 321 is housed on the free end of expansion link 34.The cross sectional dimensions of expansion link 34 makes it can pass slit 29 with moving freely.By contrast, the cross section of slide block 321 is suitable for the cross section of groove cavity 29, and for example, it has circular cross section.

Window-blind 22 is fixed on the spool 36 away from an end of pull bar 23.

Drive unit is used for from expanded position (pushing up 21 the place aheads at this position window-blind 22 at sunshade launches) to transmitting window-blind 22 retrieving position.

Drive unit comprises two linear bending resiliency urged

elements

38 and 39, and it equally also forms identical.In the pushing

member

38,39 each comprises the core bar 41 with circular cross section and is fixed to the helical spring 42 of circular core rod 41 outsides.This produces a kind of toothed elasticity of flexure tooth bar on every side.The external diameter of pushing

member

38,39 is corresponding to the A/F of groove cavity 29.In groove cavity 29, two pushing

members

38,39 are guided with the mode that prevents to buckle in its associated guide tracks 25 and 27 and can be transmitted compressive force.Its diameter is greater than slit width, and therefore, even during compressive load, they can not snap in the side through slit 30 yet.

Two

axle journals

45,46 are outstanding from spool 36 in the end, and these two

axle journals

45,46 and spool 36 be locking rotatably.Except other effects, it is used in storage reel in the

roof.Spur gear

47 and 48 is installed on

axle journal

45 and 46 respectively, and spur

gear

47 and 48 has the tooth that allows with relevant pushing

member

38,39 forward lockings engagement on its outer surface.Through more not detailed device shown two pushing

members

38,39 radially are being pressed on the associated

drives gear

47,48 so that can continue to keep

engagement.Pushing member

38,39 is positioned on the same side with respect to the axis of rotation on the associated

drives gear

47,48, and in this example, window-blind 22 extends away from spool 36 from spool 36.

Support this gear 47 and make that they can be at axle journal 421 (sics; 45) be rotated on.This is equally applicable to the gear 48 on axle journal 46.In Fig. 3, specify and transmit the used motion connection of driving moment.The description that is here launched is for two driven

wheels

47 and 48 suitable equally.

Driven wheel 47 has the shape of similar disk, and it has cylindrical peripheral surface 50, and in cylindrical peripheral surface 50, the groove 51 of diagonally extending forms the tooth of the relevant portion that is used to keep helical spring 42.Gear 47 comprises cavity 52, and cavity 52 comprises concentric bore 52, utilize this concentric bore 52 come Support Gear 47 make its can with the coaxial axle journal 45/46 of outer surface 50 on rotation.The spring shield that is used for scroll spring 54 forms cavity 52, and this scroll spring 54 forms axle journals 45/46 and is connected with rotation elasticity between the gear 47/48.For this purpose, axle journal 45/46 has the protuberance 56 in stacked on top in the relevant position, and it is as the block of the opening 57 that in the inner spring end, is provided.The outer spring end also comprises can be through the be connected opening 58 of protuberance 59 of forward, this protuberance 59 from the outer surface radial finger of cavity 52 to inside.

Functional description as from hereinafter can recognize, the rotation with respect to spool 36 takes place the corresponding size for respect to the effective diameter of the gear 47/48 of the scroll that on spool 36, forms the window-blind of rolling 22.This counterrotating tolerance approximates maximum once turnover (complete rotation).Therefore, can use scroll spring 54 with relatively shorter active path.

Expression in the accompanying drawings is not proportionally to draw.On the contrary, main points are the essential characteristic of explanation according to driving design of the present invention.Learn the size of

guide rail

26 and 27 and the therefore appropriate value of the external diameter of two elasticity of

flexure pushing members

38,39 from practice.

For the sake of completeness, should should be mentioned that the elasticity of flexure memotron of freely in vehicle, placing basically according to

spatial relationship

61 or 62 is positioned on the opposite side of associated

gear

47,48 from the angle of

respective track

26,26.

And not shown maintenance memotron 61 and the 62 fixing measures of being taked, because it is unimportant for understanding the present invention.(for example) is not shown yet surrounds

gear

47 or 48 and comprise the optional outer cover that is used to make the corresponding tangential boring that relevant elasticity of

flexure pushing member

38,39 passes through.

Shown in the function that is provided with following:

Suppose that window-blind 22 is wound up into (that is as much as possible) at first fully to spool 36 here.At roll-up state, scroll spring 54 included in two

gears

47,48 is partial to slightly.Because the deflection effect, the pushing

member

38 and 39 of engagement and therefore forward connection is at two slide block 321 (sics towards pull bar 23; 32, flexibly be partial in the direction 34) and contact in this formation.The angular force of scroll spring 54 keeps window-blind 22 between spool 36 and pull bar 23, to strain.

Begin from complete retrieving position, in the associated side 20 on these position pull bar 23 next-door neighbour's sunshade tops 21, if the user hopes to launch sunshade top activated roll-up window shade 24, he will be with the hand-tight pull bar 23 of holding.He in the direction in roof forward position to pull bar 23 is moved to position always with shading limit that he wants.Through pulled backwards pull bar 23, spool 36 is rotated in the direction that retracts window-blind 22.Simultaneously, the driven wheel 47 that connects through scroll spring 54 also turns round in identical direction with 48.It is pushed into pushing

member

38,39 in the

corresponding guide rail

26,27.

Because the scroll diameter on spool 36 continues to reduce, therefore, the quantity of the window-blind 22 that rotation is each time pulled out becomes less than the length of rotating the pushing member of being presented 38,39 each time of the driven wheel that is connected 47,48.Scroll spring 54 also has the task of this path difference of compensation.Be not difficult to draw from description, along with the expansion stroke of window-blind 22 constantly increases, these scroll springs 54 are also further tightened.

In order to regain window-blind, the user is pushing pull bar 23 with hand towards the direction of spool 36.Here, slide block 35 back into pushing

member

38,39 respectively the direction of storage tube 61 and 62.Like this, pushing

member

38,39 moves backward under the effect of hand applied force and makes driven

wheel

47,48 be connected to said pushing

member

38,39 at the respective direction forward.Through scroll spring 54 and axle

journal

45 and 46 this motion is sent to spool 36, afterwards, spool 36 will correspondingly be rolled window-blind 22 once more.

As from these explanations, understanding, user's applied force is in order to overcome the friction of pushing

member

38,39 in

guide rail

26,27 or storage tube 61,62.This power is added according to the winding difference between spool 36 and the driven wheel 47/48 and is tightened scroll spring 54 necessary power.This tightens power significantly less than the frictional force of pushing

member

38,39 in its guide rail or storage tube.This has guaranteed that pull bar 23 can stop any arbitrary position again.

Fig. 4 has shown not the setting with the additional springs device.For this purpose, two driven

wheels

47 and 48 are installed on the connecting axle 63 that next-door neighbour's spool 36 parallel axes are provided with.Two driven

wheels

47 and 48 and connecting axle 63 locking rotatably.Along the band carry one, (on the one hand) driven

wheel

47 and 48 with (on the other hand) pushing member 38, between 39 structure be connected like preamble said.

In order when regaining window-blind, rotatablely moving of driven

wheel

47 and 48 to be sent on the spool 36, a kind of cable hauling gear 64 is provided.Cable hauling gear 64 comprises cylindrical pulley 65, and it rotatably is locked on the axle journal 46 of spool 36.Connecting axle 63 carries the cable worm screw 66 that belongs to cable hauling gear 64 with the mode of rotation locking.Cable worm screw 66 comprises the pulley with sphere or taper outer surface, and its situation comprises that the cable groove is placed on the appropriate location to force the cable 67 that between pulley 35 and cable worm screw 66, extends.

One end of cotton rope 67 anchors to cylindrical pulley 65 and the other end anchors to cable worm screw 66.This part that connects the cable 67 of pulley 65 and cable worm screw 66 be positioned at window-blind 22 on the same side of the spool 36 of spool 36 outputs.

Provide the accurate dimension of cable hauling gear 64 in the functional description hereinafter.

Should suppose to be positioned at the Hou Yanchu on next-door neighbour's sunshade top 21 corresponding to the pull bar 23 of the window-blind of opening 24.At this state, the outlet that connects the cable part is positioned near the end that has than the cable worm screw 66 of minor diameter.Cable 67 is tightened up, and this also forms Necessary Tensility in window-blind 22, thereby prevents lax and guarantee slide block 35

contact pushing members

38,39.

If the user at this moment with hand through pull bar 23 hold with a firm grip window-blind 22 the forward position and also its forward direction is moved, so, as before the same, correspondingly pull out window-blind 22, and spool 36 rotated from spool 36.The rotatablely moving of spool 36 causes cable 67 to be wound up on the cylindrical pulley 65 and from cable worm screw 66 unwindings launching.Like this, the scroll diameter reduces, and causes along with the per unit path of pull bar 23 near full extension, and the anglec of rotation of spool 36 increases.Therefore, must change conversion ratio between pulley 65 and the pulley 66 makes when pull bar pushing member 38,39 more length that correspondingly moves forward during near the position of full extension.In order to achieve this end, the point of release of cable 67 on cable worm screw 66 runs to and has larger-diameter this end from having this end than minor diameter.So just realized that gear 48 slows down with respect to spool 36 gradually.Therefore, last, the end of two pushing members 39 of contact pull bar 23 is moved with identical speed with pull bar 23.Keep forward to contact between the stump of pushing member 38,39 and the slide block 35.Possible residual error is compensated by the elasticity of window-blind 22.Yet this residual error is very little.

Fig. 5 shown with according to the similar embodiment of the embodiment of Fig. 4.Two gears 47 and 48 rotatably are locked on the connecting axle 63 respectively.Realize that by means of two spur gears 69 and 71 connecting axle 63 connects with gear drive between the spool 36.Be installed on the axle journal 46, and gear 69 is connected to connecting axle 63 through scroll spring the rotatable locking of spur gear 71 (for example).Scroll spring and gear 69 can have the similar structure of the structure illustrated with combining Fig. 3.Like embodiment, also allow necessary rotary speed/path difference in this embodiment through scroll spring 54 according to Fig. 2.Yet two

gears

47 and 48 must rotate preventing that pull bar 23 from jerking and the risk of distortion synchronously in the embodiment of Fig. 5, even start under the situation of activated roll-up window shade 24 in the forward position that the user holds window-blind 22 tight in one's hands asymmetricly.

Except the window-blind of tension, sunshade top activated roll-up window shade also has two guide rails.Pushing member of operation in each guide rail, this pushing member utilizes forward to cooperate through driven wheel independently and drives.In order to manually boot window-blind, be provided with through gear drive rotatablely moving of spool is sent to driven wheel and (therefore) pushing member.During regaining activated roll-up window shade, this power works to spool through driven wheel so that produce rotatablely moving of necessary spool in the direction opposite with pushing member.
