The section structure of tensioning beam 9 also as shown in Figure 6, main body is a rectangular ellbeam body 34, is provided with notch 35 below the beam body 34, the front end of casement 11 is just pegged graft and is connected in this mouth.The top of beam body 34 is extended shaping frame 36 and form roof shape framework on beam body 34.By the rear surface 39 of top, the frame 36 of beam body 34, top 41 and front face 42 form the rectangle abdominal cavity of tensioning beam 9, and this rectangle abdominal cavity is opened wide notch 38 at the medial surface of beam body 34 to curtain rolling shaft 8 directions, this open cavity extends on the total length of tensioning beam 9, form guide groove 37, determined strut 15 free-ended cooperations and guiding relation.

With the cylinder elbow 33 of strut and the plastics forming sheet 32 that is contained in cylinder elbow butt strut medial surface after the open type notch 38 of tensioning beam 9 injects guide grooves 37, cylinder elbow 33 has only small play in guide groove 37, can in groove, be along the longitudinal movement, because plastics forming sheet 32 special complications structures play a role, make only to produce the application force that draws high the curtain direction between strut 15 and the tensioning beam 9, avoid 9 run-off the straights of tensioning beam; And owing to make plate washer at cylinder elbow 33 outside tensioning beams 9 and front face 42, the inboard has plastics forming sheet 32 spacing, so tensioning beam 9 can slippage at the axis direction of cylinder elbow 33 yet, promptly in this programme, the cooperation of tensioning beam 9 and strut 15 is drawing high parallel direction that curtain advances and is setting the correct Matching Relationship of all determining on this both direction of vertical direction on plane (having eliminated degree of freedom) with curtain.

As shown in Figure 3, the long-armed and rotating shaft of strut 15 17 keeps vertical, and shown in the four-headed arrow 43, when strut 15 long-armed swings, the plane of movement of being made up of two strut 15 working arms and the axis plane of rotating shaft 17 remain vertical; Suppose the baseplane 5 levels installation of base 4, sidewall 6 planes and curtain are set the plane keeping parallelism, as shown in Figure 4, between strut 15 and sidewall 6, pourable resin chock 25 is housed, enlarged the contact surface between the two, can reduce vibration effect, made strut 15 work extremely stable.

Actuating device 31 is contained on the sidewall 6 of base 4, its structure diagram as shown in Figure 7, in fact electrical motor 46 just is contained on the sidewall 44 of cuboid change speed gear box, output shaft stretches into casing, drive change speed gear box, the driven wheel 460 of change speed gear box respectively and the tooth bar 47,48 that is installed in parallel in the gear both sides be meshed, two tooth bars 47,48 are done antiparallel motion with the rotation of driven wheel 460.Not expression belongs to conventional structure on the supporting constructional drawing 7 of two toothed rack, is installed in parallel to each other with making linear longitudinal movement with driven wheel 460 rotations in the plane of driven wheel 460 axis normal.

Be drivening rod 28 work, two toothed rack 47,48 are fitted with bearing pin 49 respectively on the spindle nose of casing outside, and the pin-and-hole of connecting rod 28 is inserted into respectively on the bearing pin 49, has the jump ring groove on the bearing pin 49, and jump ring is housed, and guarantee that connecting rod 28 and tooth bar 47,48 reliably are hinged.

In order to illustrate the function of this case curtain 3, suppose that casement 11 rolls under the predetermincd tension effect of spring preloading device 12, it is the edge that the lower edge of tensioning beam 9 has come to the circular groove 10 of curtain rolling shaft 8 lower bottom bases 4, on this position, long-armed and the tensioning beam 9 of two struts 15 all with curtain rolling shaft 8 keeping parallelisms, two struts, 15 hinges are contained on the desired location at base 4 two ends, and the plastics forming sheet 32 of strut 15 heads leaves a little gap in the middle part of base 4.

Suppose that electrical motor 46 begins to rotate at the stop position of curtain 3, drive driven wheel 460 and make clickwise, two toothed rack are withdrawn to the change speed gear box center respectively, it is close towards the centre mutually to haul connecting rod 28, thereby drive two strut rocking arms and turn round to the inside, the long-armed of two struts 15 is the center with rotating shaft 17 just, and the parallel position that leaves with curtain rolling shaft 8 upwards rotates.Because strut free end plastics forming sheet 32 is contained in the guide groove 37 of tensioning beam 9, therefore, tensioning beam 9 just under the effect of strut 15, overcomes after the predetermincd tension of spring preloading device 12, hauls casement 11 and rises.The free-ended plastics forming sheets 32 of two struts rotate with strut 15 on one side and promote tensioning beams 9 and rise, and the guide groove 37 of an edge tensioning beam is side shifting outwardly oppositely.

Along with rotatablely moving of two struts 15, casement 11 just leaves upwards rise of base 4 by the parallel plane on strut plane.

When curtain rises to desired location, turn off electrical motor 46, under the self-locking action of drive system 31, two struts 15 just stop automatically and are fixed on the given position; And, the internal resistance moment of split-phase motor 46 and the overall gear ratio Matching Relationship of change speed gear box, drive system 31 has enough self-locking moments, does not also need additional brake.

At curtain lift top, for avoiding strut 15 and casement 11 vibrations, as shown in Figure 6, upper limb at rear auto window 2, the appropriate section of tensioning beam 9 extreme higher positions is not equipped with posting 53, posting is rectangular shape, and the direction of base 4 has V-arrangement or dovetail groove 54 relatively, and the top of tensioning beam 9 just is close in this notch 54.Posting 53 can be affixed on car body or the back window glass 2 by connection holes 55 with bolt.Like this, after curtain was raised to the top, under the precompressed compression effect of strut 15, tensioning beam 9 just was fixed in the positioning groove 54 of posting 53 reliably.The V-arrangement of positioning groove 54 or trapezoidal notch shape are tensioning beam 9 also to be entered in the groove easily locate under the situation of rocking is arranged on the one hand, are to revise when shade position has deviation on the other hand.

Start electrical motor 46 counter-rotatings when shrinking curtain, driven wheel 460 is left-hand revolution under the electrical motor effect, two toothed rack 47,48 oppositely advance from change speed gear box, driving two strut rocking arms 26 is that outwards rotate at the center with rotating shaft 17, the long-armed of two struts 15 will be the center with rotating shaft 17, to direction revolution near base 4, being contained in 32 of free-ended plastics forming sheets of strut moves along the reverse centre towards tensioning beam 9 of guide groove 37 both sides, tensioning beam 9 is also close to base 4 thereupon, curtain rolling shaft 8 under the effect of spring preloading device 12, with casement 11 rollbacks to curtain rolling shaft 8.

Curtain 3 as previously mentioned, its casement 11 all keeps slack-free flat state in arbitrary position of strut 15, under the effect of tensioning beam 9, stably is fixed on the front of vehicle window 2, therefore, the guide piece of fixing (influencing the visual field) need be set on vehicle window; When tensioning beam 9 with casement 11 rollbacks to base 4 limits the time, the operation element strut 15 of double as guide function is also disappeared on the limit of base 4 thereupon.

Even the location of 15 pairs of tensioning beams 9 of two struts and guide function also can keep stable under the remarkable heeling condition in curtain plane.

At last, when tensioning beam 9 is withdrawn into base annular groove 10 edges, curtain has been rolled up, the long-armed parallel position that is returned to curtain rolling shaft 8 of two struts 15, and actuating device 31 stops.

In order to adjust the control position of two struts 15, it can equal angles be arranged, as shown in Figure 3, a connecting rod of two connecting rods 28 is provided with the adjusting length regulating mechanism 56 of similar backguy governing screw.In addition, actuating device 31 is also according to parallel move axially of operation element do with curtain rolling shaft 8, and maintenance and two equal status requirements of strut 15 operating angles are connected on the desired location.

The actuating device of other form such as Fig. 8 and shown in Figure 9.The difference of Fig. 8 structure and Fig. 7 is not use the form of tooth bar 47,48, but symmetry is installed two crank pins 57,58 on driven wheel 460, directly be hinged with the corresponding pin-and-hole of crank pin with two connecting rods 28, make it make oppositely directed each other longitudinal movement, can drive two struts 15 equally and realize aforementioned functional.

When automobile during for other purposes supporting pneumatic system, can be as shown in Figure 9, use two reciprocating motion type cylinder 61,62 power parts as actuating device 31, cylinder 61,62 can a shared cylinder barrel 63, middle with dividing plate 64 partitions, piston 65,66 is just reciprocating in the cylinder barrel 63 of dividing plate both sides, and piston rod 67 and 68 is derived from leak free cylinder barrel 63 two respectively and previously described connecting rod 28, strut 15 are hinged.Supplying with pressurized air according to air supply pipe 69 still is the different operating modes of negative pressure ventilation, and piston 65,66 is shunk back to the two ends propelling or to the centre along cylinder barrel 63 thereupon, and piston rod 67,68 also along with doing counter motion, is worked thereby drive strut 15.

In the scheme shown in Figure 3, two struts 15 are hinged respectively on the sidewall at base 4 two ends, and the long-armed sum of two struts 15 is less than the spacing of two rotating shafts 17, and therefore, the free end of strut 15 can move in the same guide groove 37 of tensioning beam 9.But, the implementation condition of this scheme is that the lift of casement 11 is less.When the curtain lift bigger, the long-armed of strut 15 must be greater than a half of rotating shaft 17 spacings, the inner side plane of two struts 15 just must be contained on the Different Plane of base 4, its free end just need be arranged in the different guide groove of tensioning beam 9, also is the guide groove 37 that tensioning beam 9 must be provided with two dislocation at two struts 15.In other words, in the dead position of curtain rolling-in, the long-armed mutual overlapping of two struts 15, when drawing high curtain, the free end of strut 15 is oppositely moved by the two ends that this overlapping position begins along guide groove 37 towards tensioning beam 9.

Strut 15 is installed in base 4 two-end structures an advantage, and when curtain 3 was in part rise state, casement 11 relative curtain rolling shaft 8 vertical center lines rocked a bit also not feel and.

Figure 10 shows that the third embodiment of curtain 3.The coaxial gear 70 that is fixed with in the axis hole position of strut 15, hinge is in rotating shaft 17, two struts 15 are installed on the central part base of base 4 length directions side by side with gear engagement states, when a strut begins when vertical direction is rotated from stop position, another root strut is then made backward rotation with the path of motion of symmetry thereupon.The width between centers of two rotating shafts 17 is determined according to the meshing relation of two gears 70.Corresponding this structure, 31 of actuating devices need load and drive one of two struts 15 to get final product.The strut of opposite side is then driven by engaging gear 70, and other of curtain 3 and actuating device 31 required as mentioned before.

Figure 11 shows that the 4th kind of embodiment of the utility model, it adopts the curtain scheme of expansion link 71 as operation element control tensioning beam 9 motions and location.Expansion link 71 by telescopic pipe 72,72 ', 72 ", the mutual suit of 72 forms, and is installed on the base 4 its top sleeve pipe 72 ' with 9 loads of tensioning beam; Tensioning beam 9 is for only having the simple structure of the notch 35 of the casement 11 that is connected; Expansion link 71 inside are provided with the elasticity force transfer element, the head of elasticity force transfer element be connected in the push rod 72 of expansion link 71 ' on, afterbody is with actuating device 31 loads, advance under actuating device 31 effects or shrink back, thereby it is flexible to drive expansion link 71.

When actuating device 31 started, expansion link 71 was flexible thereupon under the effect of elasticity force transfer element, and tensioning beam 9 is under flexible push rod 72 ' effect, and pulling casement 11 relative bases 4 rise or are withdrawn on the volume window axle 8.In this programme, the plane of movement of tensioning beam 9 and casement 11 must keep vertical with curtain rolling shaft 8, determines the mounted angle of expansion link 71 with this.

Single expansion link structure is relatively poor to tensioning beam 9 control abilities, the easy run-off the straight of curtain, at this moment, and can be at the expansion link of installing side by side on the base 4 more than 2 71, make the head of expansion link 71 and tensioning beam 9 in the correspondence position load; Like this, several expansion links 71 are done the synchronization telescope motion under the effect of actuating device 31.

In all organization plans of this case curtain 3, the operation element of handling tensioning beam 9 all possesses makes the function of casement 11 in the stable setting of its no rigidity direction, therefore, need not auxiliary guide rail to be set for tensioning beam 9, when curtain is rolled, operation element is also lived in retirement on the limit of base 4 thereupon, can't see the thing that guide rail one class influences the visual field on the vehicle window.

Figure 12 shows that the 5th kind of organization plan of curtain 3, the fulcrum of two struts 15 is that the position of rotating shaft 17 is separately positioned on about 1/3rd positions of base 4 length directions.The characteristics of this scheme are that the strut fulcrum is positioned at the buckled zone that vehicle rear window glass outwards arches, and two end spaceses of base 4 are bigger, thereby, can nestle up rear auto window and install.

For the lift that guarantees that casement 11 is enough, two strut 15 cross-over configuration, the strut head is arranged in the same guide groove 37 of tensioning beam 9 and moves.In order to guarantee the intensity of strut 15,15 of one of two struts ' on, be provided with vertical elongated slot 75 to the free end direction, another strut 15 from fulcrum (axis hole) beginning " strut 15 ' elongated slot 75 in connect.

Figure 13 has expressed the organization plan of this actuating device 31 in detail.Actuating device 31 still belongs to the gear system that electrical motor 46 drives, and its driven wheel 76 is with 77,78 to be meshed with two rooted tooth holes respectively synchronously, is with from actuating device 31 to strut 15 transferring power synchronously by perforation.As shown in figure 14, perforation is adhesive tapes that transversal surface is flats with 77 and 78 synchronously, has equidistant arranged rectangular shape perforation 81 above the adhesive tape, and the longitudinal axis of perforation 81 is pressed the vertical direction proper alignment of adhesive tape length direction.This perforation is with 77,78 to be installed in the C shape guide rail 79 synchronously, and under the effect of guide rail 79, perforation is synchronously with 77,78 pressure that can transmit in pulling force and the setting range.Perforation be with synchronously 77,78 in C shape guide rail 79 crank motion, be stressed and do the time spent, under the protection of guide rail, prevent its flexural deformation.

Two rooted tooth holes are meshed on circumference with the conveying tooth 82 of perforation 81 with driven wheel 76 with 77 and 78 synchronously, are driven by driven wheel 76.

The coaxial respectively gear 83 and 84 that can sway that is fixed with of the root of two struts 15 is hinged in rotating shaft 17, in the rotating shaft of gear outer face jump ring 24 is housed also, to prevent gear 83,84 end float misalignment slippages.

Be that two rooted tooth holes are not installed between driven wheel 76 and the strut gear 83 with 77 and 78 supporting rigid guideway 7 fens and between driven wheel 76 and the strut gear 84 synchronously, the cornerite of C type guide rail on strut gear 83 and 84 circumference must reach 90 °, the gear 83 and 84 the gear teeth pass the opening of C shape guide rail, respectively with perforation synchronously with 77 and 78 perforation 81 engagements.

As shown in figure 13, driven wheel 76 is the opening of the C shape guide rail by being enclosed in both sides respectively, is with 77,78 to be meshed synchronously with the perforation that is symmetricly set on the tooth top of both sides; Therefore, if self-starting motor makes driven wheel 76 left-hand revolutions, driven wheel 76 just spurs two rooted tooth holes and is with 77,78 close to the gear center direction synchronously, two rooted tooth holes are with 77,78 just to drive corresponding gear 83 and 84 reversed turnings synchronously, make two struts 15 begin upwards to rotate, drive curtain and rise from dead position.When wanting the rollback curtain, just start electrical motor and make driven wheel 76 make clickwise, promote perforation and be with 77,78 outwards motions synchronously, make two strut 15 returns.This moment, perforation was with transmission pressure synchronously, because spring preloading device 12 has added the pre-fastening moment of certain backrush curtain in advance on curtain rolling shaft 8, therefore, the compressive force that the required perforation of remarkable bevelled strut 15 downward returns is with synchronously is less, and C shape guide rail 79 makes perforation can provide necessary compressive force with 77,78 synchronously.
