For the convenience of description, as shown in FIG. 1, a length direction of a transverse substrate 2 is defined as a left-right direction, a width direction of the transverse substrate 2 is defined as a front-back direction, and a height direction of the transverse substrate 2 is defined as an up-down direction. Consequently, as shown in FIG. 5, the left and right directions of the paper correspond to the rearward and forward directions, respectively; the front and back directions of the paper correspond to the upward and downward directions, respectively; and the upper and lower directions of the paper correspond to the rightward and leftward directions, respectively.
[0050] First embodiment:
[0051] As shown in FIGs. 1-10, the first embodiment of the present disclosure provides a louver awning capable of rotating and retracting. The louver awning comprises pillars 1, transverse substrates 2, longitudinal substrates 3, and louvers 4. The pillars 1, transverse substrates 2, and longitudinal substrates 3 are bolted together, and the transverse substrates 2 and the longitudinal substrates 3 constitute a substrate frame. The pillars 1 are configured to support the substrate frame. Each of the transverse substrates 2 is provided with a guide rod 203, each of front and back ends of one of the louvers 4 is provided with a connecting rod 402, an offset wheel 401 is disposed on the connecting rod 402, and the offset wheel 401 moves along the guide rod 203. The louver awning further comprises a louver rotating drive mechanism and a louver moving drive mechanism, the louver rotating drive mechanism is configured to rotate the louvers 4, and the louver moving drive mechanism is configured to drive the louvers 4 to move to a left-side end or a right-side end of the substrate frame.
[0052] As an example, the pillars 1, transverse substrates 2, and longitudinal substrates 3 are fixedly connected relative to each other, and the louvers 4 are disposed within the substrate frame. Operators can drive the louvers 4 to rotate a specific angle through the louver rotating drive mechanism to adjust a light transmittance of the louver awning, and can push the louvers 4 to one side of the substrate frame through the louver moving drive mechanism, so that the louvers 4 do not obstruct the louver awning, allowing for sunbathing and stargazing.
[0053] As another example, the louver awning of the present disclosure comprises two transverse substrates 2, two longitudinal substrates 3, and four pillars. The transverse substrates 2 extends along the left-right direction, the longitudinal substrates 3 extends along the front-back direction, and the pillars 1 extends along the up-down direction. The transverse substrates 2, the longitudinal substrates 3, and the pillars 1 are fixedly connected to each other by bolts and are pairwise orthogonal. A reinforcing rod 18 is further provided between the two transverse substrates 2 for improving stability.
[0054] Preferably, as shown in FIGs. 2-4, the louver rotating drive mechanism comprises a rotating drive rod 5, a rotating transmission member 6, a first adapter plate 7, and parallel plates 8. Each of the parallel plates 8 is sleeved around an outer periphery surface of a front-end connecting rod 402 of one of the louvers 4. A front-end surface of the parallel plate 8 is provided with a central fixing member 802, an upper-side fixing member 801, and a lower-side fixing member 803, a centerline of the central fixing member 802 of the parallel plate 8 coincides with a centerline of the connecting rod 402, and the upper-side fixing member 801 and the lower-side fixing member 803 of the parallel plate 8 are symmetrically disposed at two sides of the central fixing member 802 of the parallel plate 8. The central fixing members 802, the upper-side fixing members 801, and the lower-side fixing members 803 of the parallel plates 8 are connected to each other by traction ropes 9, respectively. The rotating drive rod 5 is connected to an input of the rotating transmission member 6, an output of the rotating transmission member 6 is connected to the first adapter plate 7, and the first adapter plate 7 is fixedly connected to a parallel plate 8 disposed at a left-end louver 4 among the louvers 4. The left-end louver 4 is next to the left-side end of the substrate frame.
[0055] Further, as an example, the number of parallel plates 8 corresponds to the number of louvers 4, and each of the parallel plates 8 is disposed at a front-end surface of the front-end connecting rod 402 of one of the louvers 4. When the parallel plate 8 rotates, the corresponding louvre 4 is driven to rotate together through the front-end connecting rod 402.
[0056] Further, as shown in FIG. 4, the central fixing member 802, the upper-side fixing member 801, and the lower-side fixing member 803 all adopt grooved wheels each of which has a center hole. Each of the center holes is threaded with a bolt, and the parallel plate 8 is correspondingly provided with three threaded holes to match the bolts, so that the central fixing member 802, the upper-side fixing member 801, and the lower-side fixing member 803 are fixedly connected to the parallel plate 8.
[0057] Further, as shown in FIGs. 2 and 4, the traction ropes 9 are wrapped around the central fixing members 802, the upper-side fixing members 801, and the lower-side fixing members 803 of the parallel plates 8, respectively, and is relatively stable. When the parallel plate 8 of the left-end louver 4 rotates clockwise together with the first adapter plate 7, the traction rope 9 between the central fixing members 802 does not move (i.e., the centerline of each of the central fixing members 802 coincides with the centerline of the corresponding connecting rod 402 and the traction rope 9 therebetween does not cause a relative displacement) , and the traction rope 9 between the lower-side fixing members 803 is subjected to a clockwise pulling force, and then drives each of the parallel plates 8 to rotate clockwise around the centerline of the corresponding connecting rod 402, which in turn drives the louvers 4 to rotate clockwise. The parallel plates 8 rotate clockwise by a maximum angle of 90 degrees, at which time the louvers 4 will be in a vertical state (viewing from the front-back direction) . When the parallel plate 8 of the left-end louver 4 rotates counterclockwise together with the first adapter plate 7, the traction rope 9 between the. upper-side fixing members 801 is subjected to a counterclockwise pulling force, and then drives each of the parallel plates 8 to rotate counterclockwise around the centerline of the corresponding connecting rod 402, which in turn drives the louvers 4 to rotate counterclockwise, at which time the louvers 4 will be in a horizontal state (viewing from the front-back direction) .
[0058] Preferably, as shown in FIGs. 2, 3, and 5, the louver moving drive mechanism comprises a moving drive rod 10, a first moving transmission member 11, a second moving transmission member, and moving drive blocks 16. The moving drive blocks 16 are connected to connecting rods 402 of a right-end louver 4 among the louvers 4, respectively, and the right-end louver 4 is next to the right-side end of the substrate frame. The moving drive rod 10 is connected to an input of the first moving transmission member 11, an output of the first moving transmission member 11 is connected to an input of the second moving transmission member, and each of the moving drive blocks 16 is disposed at an output of the second moving transmission member and is configured to move when driven by the second moving transmission member. Further, as an example, the louver moving drive mechanism drives the louvers 4 towards the left-side end of the substrate frame, the left-end louver 4 only rotates but does not move, and the remaining louvers 4 both rotate and move. As an example, each of the transverse substrates 2 is provided with a guide groove 201, and the connecting rods 402 of the remaining louvers 4 are slidably provided in the guide groove 201, so that the remaining louvers 4 move towards the left-side end of the substrate frame to abut against the left-end louver 4.
[0059] Preferably, as shown in FIG. 5, the second moving transmission member comprises at least one driving shaft 12, fixed shafts 14, driving synchronous pulleys 13, driven synchronous pulleys 15, and synchronous belts 17. The driving shaft 12 penetrates front and back transverse substrates 2 and is connected to each of the front and back transverse substrates 2 through a bearing base. The driving synchronous pulleys 13 are sleeved around the driving shaft 12, and the fixed shafts 14 are disposed at a right-side end of the two transverse substrates 2. The fixed shafts 14 are fixedly connected to the two transverse substrates 2, each of the driven synchronous pulleys 15 is rotatably disposed at one of the fixed shafts 14 through a bearing, and each of the synchronous belts 17 connects one of the driving synchronous pulleys 13 with a corresponding driven synchronous pulley 15. Each of the moving drive blocks 16 is disposed on one of the synchronous belts 17. As an example, the louver awning of the present disclosure comprises two driving synchronous pulleys 13, two driven synchronous pulleys 15, and one driving shaft 12. The driving shaft 12 penetrates the front and back transverse substrates 2 along the front-back direction, and the driving shaft 12 can rotate in the two transverse substrates 2. The two driving synchronous pulleys 13 are sleeved around outer peripheral surfaces of front and back ends of the driving shaft 12. As another example, the louver awning of the present disclosure comprises two fixed shafts 14, and each of the fixed shafts 14 penetrates and fixedly connects one of the two transverse substrates 2. As another example, the louver awning of the present disclosure comprises two moving drive blocks 16.
[0060] Further, as shown in FIG. 6, a back-end connecting rod 402 of each of the louvers 4 is provided with a connecting-rod central fixing member 4020 to ensure that both the front and back ends of each of the louvers 4 move synchronously in the guide groove 201 when the louvers 4 are in motion. The connecting-rod central fixing member 4020 is of the same structure as the central fixing member 802 of the parallel plate 8, and adjacent connecting-rod central fixing members 4020 are also connected through a traction rope 9, ensuring that the front and back ends of each of the louvers 4 move synchronously in the guide groove 201 when driven by the moving drive blocks 16, avoiding offsets caused by the louvers 4.
[0061] Preferably, as shown in FIG. 3, the rotating transmission member 6 and the first moving transmission member 11 adopt worm gear and worm wheel transmission, and the moving drive rod 10 and the rotating drive rod 5 are driven manually or electrically. As an example, the rotating transmission member 6 comprises a base, an end cap, a worm wheel, and a worm gear. The worm gear is connected to a top of the rotating drive rod 5, and the worm wheel engages with the worm gear and is connected to the first adapter plate 7 via an output shaft of the rotating transmission member 6. Accordingly, the first moving transmission member 11 is of the same structure as the rotating transmission member 6, i.e., the worm gear is connected to a top of the moving drive rod 10, and the worm wheel engages with the worm gear and is connected to the driving shaft 12 in a drivable manner via an output shaft of the first moving transmission member 11 (for example, the driving shaft 12 can directly serve as the output shaft of the first moving transmission member 11) . The worm wheel and worm gear are disposed within the base and the end cap, and the base and end cap are configured to protect the engaging of the worm wheel and worm gear. As an example, a bottom of the rotating drive rod 5 is provided with a first ring, a bottom of the moving drive rod 10 is provided with a second ring, facilitating operators to manually rotate the rotating drive rod 5 and moving drive rod 10. As another example, the rotating drive rod 5 and the moving drive rod 10 can also be achieved using electric or other methods.
[0062] Preferably, as shown in FIGs. 7-9, each of the louvers 4 comprises a louver body 403, louver covers 404, and connecting seats 405. Each of the connecting seats 405 is bolted to the louver body 403 and is fixedly connected to the connecting rod 402, the louver covers 404 are bolted at front-end and back-end surfaces of the louver body 403, respectively, and each of the connecting rods 402 penetrates one of the louver covers 404.

That is, a left-lower edge of a louver body 403 is pressed against a right-lower edge of a louver body 403 disposed at left side of the previous one, at which time, the louvers 4 are in the horizontal state, ensuring that the light is completely blocked by the louver body 403.
[0064] Further, a top surface of the louver body 403 is a beveled surface. As an example, the top surface of the louver body 403 is inclined from left to right, and the right-lower edge of the louver body 403 forms a drainage groove, so that when it rains, the rainwater will flow along the top surface of the louver body 403 to the drainage groove, completing the discharge of the rainwater and directing the rainwater into the drainage groove, thereby preventing the rainwater from accumulating on the louver body 403.
