Description

Technical Field

[0001] The utility model relates to the technical field of outdoor sunshade products, in particular to a slatted sunshade. Background Art

[0002] In order to provide shade and shelter from the rain, awnings are usually installed above the doors and windows of buildings. Awnings generally come in two types: shade cloth and slats. Awnings that use shade cloth are usually provided with a driving mechanism, through which the shade cloth can be freely extended or retracted as needed to meet people's living needs. However, awnings that use shade cloth have a single function and cannot display the proper mood. Awnings that use slats are provided with a driving mechanism, through which the slats can be rotated to an angle to meet the needs of lighting and shading. However, when awnings that use slats need to bask in the sun or view the starry sky, some sunlight or the starry sky will always be blocked by the slats, which cannot meet people's living needs.

[0003] To solve the above problems, the prior art discloses a rotatable and retractable louver awning, publication number CN219671902U, which includes a plurality of vertical columns, a plurality of horizontal base plates, a plurality of vertical base plates, and a plurality of louvers, wherein the vertical columns, the horizontal base plates, and the vertical base plates are fixedly connected, and the horizontal base plates and the vertical base plates constitute a base plate frame; connecting rods are provided at both ends of the louvers, and the louvers are connected to the base plate frame through the connecting rods; the louver also includes a louver rotation drive mechanism and a louver movement drive mechanism, and the louver rotation drive mechanism includes a main rotation drive assembly, a main transmission rod, and a slave rotation transmission assembly.

[0004] Although the above patent has improved the blind awning to a certain extent, it still has the following defects:

[0005] 1. Two rotating drive rods are provided in this patent, which respectively drive the rotation and movement of the blinds. Although the patent specification states that an electric drive method can be adopted, the rotating drive rods in this patent are located on the outside of the horizontal substrate, and the appearance is not beautiful enough.

[0006] 2. In this patent, adjacent blinds are connected by traction ropes, and the connecting ends of the traction ropes are connected by jackets. When the traction ropes are stretched, the jackets may fall off. In addition, when adjacent blinds are close to each other, the contraction direction of the traction ropes is non-directional, and they may bend upward, downward, or diagonally, which may cause resistance when the blinds are tightened.

[0007] 3. The patent is provided with a mobile drive block, which is connected to the connecting rod of the right end shutter. In the attached drawings of the patent, an L-shaped plate is also provided between the mobile drive block and the connecting rod of the shutter. Due to the existence of the L-shaped plate, the distance between the mobile drive block and the connecting rod is too large, and the torque is large. When the shutter is pulled to move, the required driving force is greater, manual driving will be more laborious, and motor driving will generate a greater demand for the torque of the motor.

[0008] In summary, the patent for a rotatable and retractable louver awning with publication number CN219671902U can be further improved. Utility Model Content

[0050] The slatted awning involved in the utility model has the following working steps:

[0051] S1: The operator first assembles the above-mentioned components;

[0052] S2: When the rotation angle of the slat 8 needs to be adjusted, the operator starts the rotary drive motor 4, and the rotary drive motor 4 drives the main transmission rod 6 to rotate through the reversing mechanism 5. The rotation of the main transmission rod 6 drives the driven worm sleeve to rotate, and then the driven worm sleeve is meshed with the driven worm wheel, the driven worm wheel rotates, the slave rotary output rod rotates accordingly, and then the connecting rod 801 fixedly connected to the slave rotary output rod also rotates accordingly, and the rotation of the connecting rod 801 drives the slat 8 to rotate. The angle of rotation of the slat 8 is 0-90°. The rotation direction of the slat 8 is changed by controlling the rotation direction of the rotary drive motor 4 (that is, the slat 8 rotates clockwise or counterclockwise). When the slat 8 rotates 90° clockwise, the slat 8 is in a vertical state; when the slat 8 rotates back to 0° counterclockwise, the slat 8 is in a horizontal state, and the edges of adjacent slats 8 overlap each other to achieve the sunshade function. The operator can adjust the rotation angle of the slat 8 according to the lighting requirements to achieve the desired lighting.

[0053] S3: When the slat 8 needs to be moved to the left end, the operator first performs step S2 to rotate the slat 8 clockwise to 90°, at which time the slat 8 is in a vertical state. Then the operator starts the mobile drive motor 13, and the mobile drive motor 13 works and rotates through the mobile drive rod 14 through the active shaft, the active synchronous pulley, the synchronous belt 12, the driven synchronous pulley, the mobile drive block 11, and the "Ω"-shaped ring sleeve 1103 to apply a leftward translation thrust to the rightmost slat 8, and the offset wheel 802 on the slat 8 moves to the left on the guide rod, and the rightmost slat 8 slides to the left along the guide groove and abuts against the slat 8 on the left, thereby pushing the slat 8 on the left to move to the left together, until all the slats 8 move to the left side of the substrate frame, and at this time there is no obstruction on the substrate frame, which can meet the needs of users to bask in the sun or watch the stars; in the process of the slat 8 sliding to the left, the chain 10 between adjacent slats 8 gradually changes from a tight state to a loose state.

[0054] When the slat 8 needs to be moved out from the left side, the operator controls the mobile drive motor 13 to reverse, the mobile drive motor 13 works and rotates through the mobile drive rod 14, and the rightmost slat 8 is applied with a rightward translational pulling force through the active shaft, the active synchronous pulley, the synchronous belt 12, the driven synchronous pulley, the mobile drive block 11, and the "Ω"-shaped ring sleeve 1103, and the rightmost slat 8 slides to the right along the guide groove. At this time, the chain 10 between the adjacent slats 8 gradually changes from a relaxed state to a tight state, and the rightmost slat 8 applies a rightward pulling force to the left slat 8 through the chain 10, so that the slat 8 is moved out from the left side of the base frame. At this time, if the slat 8 needs to be rotated to a horizontal position, step S2 needs to be executed to rotate the slat 8 counterclockwise by 90°.

[0055] The slat awning involved in the utility model is provided with a slat moving drive assembly and a slat rotating drive assembly. The slat rotating drive assembly is used to drive the slats 8 to rotate a certain angle to meet the needs of consumers for daylighting rate; the slat moving drive assembly is used to move the slats 8 to the left side to meet the needs of sunbathing or observing the stars. The functional diversity solves the defect of the single function of the sunshade cloth in the prior art. The utility model provides a chain 10 to replace the traction rope in the prior art, and uses an "Ω"-shaped ring sleeve 1103 to replace the L-shaped plate in the prior art, which can solve the defects in the prior art.

[0056] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
