According to the lifting type sculpture table, the guide grooves are matched with theguide blocks, the guide blocks are fixedly connected with the connecting plate, then the connecting plate can be prevented from shifting in the up-and-down movement, so that the connecting plate is always in a horizontal state in the up-and-down movement, and then the connecting plate is more stable.

The invention relates to an apparatus and method for making flexible thin-film solar cells. A plurality of alternately arranged cutters and cutter grooves are disposed cooperatively on upper and lower rollers. After cutting, I-type and II-type strip thin-film solar cells arranged alternately are obtained. The strip thin-film solar cells have two edge tips in different directions, and the edge tips of the adjacent strip thin-film solar cells are in the same direction. In the use, the adjacent I-type or II-type strip thin-film solar cells are subjected to plane rotation of 180 degrees and then connected with the II-type or I-type strip thin-film solar cells, so that the adjacent edge tips of the I-type and II-type strip thin-film solar cells connected after rotation are in different directions; and therefore, the flexible thin-film solar cells can be prevented from cutting conductive material in the use, and the stability of electrical connection of the flexible thin-film solar cells is ensured.

The invention discloses a circle-center-variable drop-shaped infolding gear rotating mechanism. The mechanism comprises a rotating shaft cover and rotating shafts arranged at the two ends of the rotating shaft cover, each rotating shaft comprises two sets of main movable blocks, and the main movable blocks are connected with a concave wheel connecting plate, center movable blocks, two sets of gearshafts, two sets of side edge movable blocks and two sets of cams, and a longitudinal sliding block is arranged at the lower bottom of each center movable block; the cams are provided with positioning grooves, a longitudinal sliding groove is formed in the lower bottom of the concave wheel connecting plate, flat position sliding grooves drive flat positions to rotate and synchronously slide, third connecting columns slide in transverse sliding grooves, second connecting columns rotate in side edge connecting holes, and first connecting columns slide in long track curve grooves to achieve compensation of the screen unfolding state; and a longitudinal sliding block and the longitudinal sliding groove are connected in a sliding manner to achieve positioning and auxiliary synchronization of the screen unfolding initial state, positioning grooves and positioning blocks are fixed to drive the cams to rotate, the cams and the concave wheel connecting plate are matched in a concave-convex manner to achieve clamping point self-locking in the 0-degree state and the 180-degree state, and torsion is generated to achieve rotation without abnormal sounds.

The invention discloses a driving type water-drop-form two-side synchronous rotating mechanism. The driving type water-drop-form two-side synchronous rotating mechanism comprises a structure main bodywhich is composed of a synchronous mechanism, a driving steering mechanism and an auxiliary mechanism, wherein the synchronous mechanism comprises gears and racks, the driving steering mechanism comprises a rotating shaft cover and a plurality of movable blocks, and the auxiliary mechanism comprises U springs for realizing torsion and screen locking. The synchronization is achieved through gear sets composed of the gears and the racks, and the required displacement for bending is achieved through the combination between inclined grooves and nails, and the combination between fixed teeth and positioning racks; through the combination between an inner arc and a movable plate nail, the combination between movable plate sliding grooves and nails, side plate sliding grooves and the movable plate nail, the avoiding space can be reserved through bending in the form of water drops, then the whole can reserve the space in the form of the water drops and achieve seamless transition in the bending process, the overall structural design is simpler and more effective, the rotating requirement of a folding screen is met, the overall design is simpler and more effective, the displacement compensation and screen locking functions are met, the space is reserved in the form of the water drops, and the seamless transition is achieved in the bending process.
