One rotation group 60, this rotation group 60 is provided with one and is fixedly arranged on connecting support 61 on this wagon box 12, this connecting support 61 is provided with a bearing 62, with the pivot 63 that is pivoted, the side of this pivot 63 is then installed with a scrolling part 64 and the relative free end 142 of this swing arm 14, wherein the present invention is not as limit, in other embodiments this swing arm 14 also can directly and this scrolling part 64 fix, or fix with this scrolling part 64 and this pivot 63 simultaneously, in addition, this scrolling part 64 such as drawing is depicted as a fluted disc, fluted disc is not that limitation is round tooth dish, this scrolling part 64 is fixed in the part of periphery and this flexible body coupling link 50, and this scrolling part 64 can be fixedly arranged on pivot 63, also can be fixedly arranged on a free end 142 of swing arm 14, when support 140 for this swing arm 14 rotates, this scrolling part 64 can be synchronously driven to rotate centered by this pivot 63.
When using when furling shade 13, as Fig. 1, shown in Fig. 3 to Fig. 5, now initial condition masks wagon box 12 completely for this shade 13, and the propulsion source 150 of this lifting furling mechanism 15 starts capstan group 151 rotates, plural cable wire 152 is synchronously furled, and pull the closed end 141 of this swing arm 14, this swing arm 14 of interlock rotates towards this capstan group 151 direction centered by this pivot 63, and while this swing arm 14 rotates, can rotate by this scrolling part 64 of synchronous interlock, pull this flexible body coupling link 50 towards differing from the retracting of this elastic element 40 direction, and this elastic element 40 is extended resiliently, to shorten the distance of this scrolling part 64 and this elastic element 40, progressively rotate via the capstan of this capstan group 151 according to this, plural cable wire 152 is made to pull this swing arm 14, with sequentially interlock scrolling part 64, flexible body coupling link 50, this elastic element 40 is stretched, until as shown in Figure 5, this swing arm 14 has rotated to desired location, namely this shade 13 has furled, now, this elastic element 40 is in extended state, in addition, the elastic element 40 of the present embodiment can according to required elastic force, rotate this trimming piece 30, can move in horizontal direction to make this trimming piece 30, so as to the distance shortened or increase between 31, this first joint portion and this pivot 63, and then according to the needs of user, adjust the elastic force of this elastic element 40.
Otherwise, when this shade 13 being shielded in wagon box 12, now, plural cable wire 152 can be rotated pull-out by this capstan group 151 gradually, and be subject to the tensile-elasticity impact of this elastic element 40, swing arm 14 1 aspect is subject to the impact of plural cable wire 152 pulling force, be subject to the tensile-elasticity effect of this elastic element 40 on the other hand, swing arm 14 can be made to rotate towards truck 10 rear, rotate with this scrolling part 64 of interlock, and this flexible body coupling link 50 is moved towards this elastic element 40 direction, the pulling force of plural cable wire 152 is subject to for this elastic element 40, and coordinate the gravity of this swing arm 14, slowly return back to unstretched state, and by swing arm 14 stabilized rotation, reach the desired location that this shade 13 covers wagon box 12.
Now, if this shade 13 is in the process of covering wagon box 12, run into when having high wind to be blown by wagon box rear, the present embodiment can not only lean on the gravity of this swing arm 14 itself, more include the elastic pulling force of elastic element 40, can be stable and safe this shade 13 is shielded in wagon box 12, to avoid as known technology causes disorder between plural cable wire 152 and capstan group 151, and then can reduce the loss being elevated furling mechanism 15.
As shown in FIG. 6 and 7; it is second embodiment of the invention; wherein this flexible body coupling link 52 is a belt or a cable wire; and this scrolling part 65 is a belt pulley or a hinge wheel relatively; and the effect that also can have as first embodiment of the invention, this flexible body coupling link 52 of above embodiment and this scrolling part 65 are only casehistory, and the present invention is not as restriction; can the linkage effect person identical with the present embodiment be produced, be in protection scope of the present invention.
Refer to shown in Fig. 8, it is third embodiment of the present invention figure, wherein most identical with the first embodiment, difference is that the support 140 of this swing arm 14 is arranged between this scrolling part 64 and this connecting support (not shown), and the support 140 as this swing arm 14 of Fig. 3 to Fig. 5 is arranged at the side that this scrolling part 64 differs from this connecting support 61.
Refer to shown in Fig. 9, it is fourth embodiment of the present invention figure, wherein this permanent seat 20 can oppositely be arranged with the position relative to this wagon box 12 of this connecting support (not shown), other then duplicate with the first embodiment, and coordinate the reverse setting of this permanent seat 20 and this connecting support, the reverse front being located at scrolling part 64 of this flexible body coupling link 50 and elastic element 40 is towards headstock direction, and equally can when this shade 13 (as shown in Figure 1) is in rolled condition, can be stretched this elastic element 40, when needing to cover this wagon box 12 for this shade 13, this elastic element 40 still can provide required elastic pulling force, make this swing arm 14 together with this shade 13 energy operating stably.
Refer to shown in Figure 10, it is another embodiment of scrolling part of the present invention, wherein, scrolling part of the present invention does not limit necessarily as the circle of the first embodiment, but at least establish curved for the periphery of this scrolling part 66 retracting in this scrolling part 66, can conveniently furl, but the present invention is not subject to the limits, in fact, only need form the position that can furl this flexible body coupling link 53 at this scrolling part 66 part periphery, as shown in Figure 10, this scrolling part 66 can arrange semicircular in shape, but this is only citing, the present invention is not subject to the limits, can be oval, the distortion such as circular arc or polygon.Even non-single element, such as shown in Figure 13, it is that scrolling part of the present invention one implements illustration again, wherein this scrolling part is provided with two, and be located on the periphery of support 14 both sides respectively, as shown in the figure, two scrolling parts are respectively a registration mast 67, and a registration mast 67 is wherein fixed with this flexible body coupling link 50, and another registration mast 67 is resisted against the stage casing of this flexible body coupling link 50, rotate by this support 14, make two registration masts 67 also this flexible body coupling link 50 of stretchy, synchronous this elastic element 40 of drive stretching, to reach effect of the above-mentioned each embodiment of the present invention.
The above-mentioned each embodiment of lifting fastening mechanism of the present invention not only limits the swing arm being applied to single lever-type, and can according to the swing arm design of different truck, all the present invention can be applied, as shown in FIG. 11 and 12, wherein this swing arm 143 is designs in double rod type, and in this swing arm 143, there are two connecting rods 144, connecting rod 144 end is wherein fixed on this scrolling part, and be pivoted with a trace 145 in desired location between two connecting rods 144, double rod type by this swing arm 143 designs, and more can increase the stability that swing arm 143 swings.
The present invention describes by the above embodiments and change case, all embodiments of the present invention and change case are only exemplary and restricted, based on connotation of the present invention and scope, and the various changes of lifting fastening mechanism that the truck wagon box shade comprising above-mentioned feature opens and closes are the present invention and contain.
