An electrically driven internal rotating louver system

Abstract

This invention proposes an electrically driven internal rotating louver system, comprising multiple evenly spaced rotating louver structures. Each rotating louver structure has two ends connected to the walls on either side. Each rotating louver structure includes a louver body and a drive structure. A circular tube is located at the center of the louver body, and the drive structure is built into the circular tube. The drive structure includes a motor, a motor tube, a motor pusher, and a reducer. Both ends of the motor tube are fixedly connected to the walls on either side. The motor is located inside the motor tube and is connected to the motor pusher via the reducer. A slot is provided at one end of the inner wall of the circular tube, and the end of the motor pusher furthest from the motor is inserted into the slot. This allows the motor pusher to engage with the slot and rotate the louver body when the motor drives it. Each louver body is independently controlled by its corresponding built-in drive structure, enabling each louver body to operate independently, open or close, achieving a rotation adjustment of 0~90° to meet the shading needs of special occasions.

Description

Technical Field

[0001] This invention relates to the field of louver technology, and more specifically, to an electrically driven internally driven rotating louver system. Background Technology

[0002] In some special shading scenarios, such as villa areas under courtyards where lighting and shading are required, each louver needs to operate independently.

[0003] Existing electric louver systems mostly use external drive or centralized control, such as CN117345097A. The drive structure is exposed and complex, relying on mechanical transmission of gears, support racks and central shafts. The exposed components are susceptible to environmental influences (such as dust and oxidation), resulting in reduced lifespan and high maintenance costs. Furthermore, since all louvers are driven uniformly through the central shaft, it is impossible to achieve independent angle adjustment of individual louvers, resulting in insufficient flexibility.

[0004] Therefore, a new type of rotating louver system with built-in drive and independent rotation of each leaf is needed. Summary of the Invention

[0005] In view of this, in order to solve the above problems, the present invention proposes an electric internal drive rotating louver system, in which a drive structure 12 is built into a circular tube 111, a motor 121 drives a motor pusher 124 through a reducer, and the pusher cooperates with the slot 112 of the circular tube 111 to drive the louver to rotate; a nylon gasket 13 reduces friction; a U-shaped / L-shaped mounting bracket 16 is fixed to the pre-embedded steel pipe 14 to ensure stability; and a double arc panel improves wind pressure resistance.

[0006] An electrically driven internally driven rotating louver system includes multiple evenly spaced rotating louver structures 10, each with its two ends connected to a wall on one side. The system is characterized in that each rotating louver structure 10 includes a louver body 11 and a drive structure 12. A circular tube 111 is located at the center of the louver body 11, and the drive structure 12 is housed within the circular tube 111. The drive structure 12 includes a motor 121, a motor tube 122, a motor pusher 124, and a reducer. Both ends of the motor tube 122 are fixedly connected to the walls on both sides, and the motor 121 is located within the motor tube. Inside 122, the motor 121 is connected to the motor push head 124 through a reducer. One end of the inner wall of the round tube 111 is provided with a slot 112. The end of the motor push head 124 away from the motor 121 is inserted into the slot 112, so that when the motor 121 drives the motor push head 124 to move, the motor push head 124 can cooperate with the slot 112 to drive the louver body 11 to rotate. Each louver body 11 is independently controlled by its corresponding built-in drive structure 12, so that each louver body 11 can operate, open or close independently, and achieve rotation adjustment from 0 to 90° to meet the sunshade needs of special occasions.

[0007] Furthermore, the motor tube 122 is fitted with at least two symmetrically arranged gaskets 13, the outer edge of the gaskets 13 is in contact with the inner wall of the round tube 111, and the gaskets 13 are used to provide lubrication to the round tube 111 and reduce noise when the round tube 111 rotates.

[0008] Furthermore, the rotating louver structure 10 is connected to the wall via a pre-embedded steel pipe 14, a U-shaped mounting bracket 15, and an L-shaped mounting bracket 16. The motor pipe 122 has L-shaped mounting brackets 16 at both ends. One end of the L-shaped mounting bracket 16 is connected to the motor pipe 122, and the other end is connected to one side of the U-shaped bottom surface of the U-shaped mounting bracket 15. The steel pipe 14 is connected to the inner side of the U-shape of the U-shaped mounting bracket 15. The motor pipe 122 is fixed by the U-shaped mounting bracket 15 and the L-shaped mounting bracket 16.

[0009] Furthermore, the louver body 11 also includes a first blade skeleton 113, a second blade skeleton 114, and a support piece 115. The upper and lower ends of the louver body 11 are provided with a first blade skeleton 113. The middle part of the blade skeletons at the upper and lower ends extends towards the circular tube 111 with a second blade skeleton 114. The second blade skeleton 114 is connected to the circular tube 111 but does not penetrate the circular tube 111, forming a distributed support structure.

[0010] Furthermore, both ends of the circular tube 111 are provided with support plates 115 in both the upper and lower directions. One end of the support plate 115 is attached to the outer wall of the circular tube 111, and the other end is connected to the first blade skeleton 113 to disperse the stress when the louver rotates.

[0011] Furthermore, the louver body 11 also includes a double-arc shuttle-shaped panel 116, which covers the outside of the first blade skeleton 113, the support piece 115 and the circular tube 111, to enhance structural strength and optimize airflow distribution.

[0012] Furthermore, the reducer is a planetary gear reducer, used to reduce the speed of motor 121 and increase the output torque, so that the louver rotation is smooth.

[0013] Furthermore, the end of the motor tube 122 near the motor push head 124 is provided with an opening 123. The width of the opening 123 is greater than the movement trajectory of the motor push head 124, so as to avoid interference between the motor push head 124 and the motor tube 122 when the motor push head 124 rotates.

[0014] In some embodiments, the radius of curvature of the double-arc shuttle-shaped panel 116 is 50mm~200mm and the arc spacing is 10mm~30mm, which is used to reduce the impact of wind pressure on the louvers while providing shading.

[0015] Beneficial effects of the present invention: The present invention proposes an electrically driven internally driven rotating louver system, comprising a plurality of evenly spaced rotating louver structures 10. The two ends of each rotating louver structure 10 are respectively connected to the walls on both sides. Each rotating louver structure 10 includes a louver body 11 and a drive structure 12. A circular tube 111 is provided at the center of the louver body 11, and the drive structure 12 is built into the circular tube 111. The drive structure 12 includes a motor 121, a motor tube 122, a motor pusher 124, and a reducer. The two ends of the motor tube 122 are fixedly connected to the walls on both sides. The motor 121 is equipped with... Inside the motor tube 122, the motor 121 is connected to the motor push head 124 via a reducer. One end of the inner wall of the round tube 111 is provided with a slot 112. The end of the motor push head 124 away from the motor 121 is inserted into the slot 112, so that when the motor 121 drives the motor push head 124 to move, the motor push head 124 can cooperate with the slot 112 to drive the louver body 11 to rotate.

[0027] An electrically driven internally driven rotating louver system includes multiple evenly spaced rotating louver structures 10, each with its two ends connected to a wall on one side. The system is characterized in that each rotating louver structure 10 includes a louver body 11 and a drive structure 12. A circular tube 111 is located at the center of the louver body 11, and the drive structure 12 is housed within the circular tube 111. The drive structure 12 includes a motor 121, a motor tube 122, a motor pusher 124, and a reducer. Both ends of the motor tube 122 are fixedly connected to the walls on both sides, and the motor 121 is located within the motor tube. Inside 122, the motor 121 is connected to the motor push head 124 through a reducer. One end of the inner wall of the round tube 111 is provided with a slot 112. The end of the motor push head 124 away from the motor 121 is inserted into the slot 112, so that when the motor 121 drives the motor push head 124 to move, the motor push head 124 can cooperate with the slot 112 to drive the louver body 11 to rotate. Each louver body 11 is independently controlled by its corresponding built-in drive structure 12, so that each louver body 11 can operate, open or close independently, and achieve rotation adjustment from 0 to 90° to meet the sunshade needs of special occasions.

[0028] The motor tube 122 is fitted with at least two symmetrically arranged gaskets 13. The outer edge of the gasket 13 contacts the inner wall of the round tube 111. The gasket 13 is used to provide lubrication to the round tube 111 when it rotates and to reduce noise.

[0029] The edge of the gasket 13 that contacts the inner wall of the round tube 111 is the friction surface 131. The friction surface 131 has chamfers 132 on both sides to reduce frictional resistance.

[0030] The friction surface 131 has a width of 0.5~5mm and a chamfer angle of 30°~45° to further reduce rotational resistance.

[0031] The gasket 13 is made of plastic or nylon, preferably nylon, which has good weather resistance and is not easily oxidized.

[0032] The edge of the gasket 13 is provided with symmetrical set screw holes 133 for locking with the motor tube 122 by set screws.

[0033] The rotating louver structure 10 is connected to the wall via a pre-embedded steel pipe 14, a U-shaped mounting bracket 15, and an L-shaped mounting bracket 16. The motor pipe 122 has L-shaped mounting brackets 16 at both ends. One end of the L-shaped mounting bracket 16 is connected to the motor pipe 122, and the other end is connected to one side of the U-shaped bottom surface of the U-shaped mounting bracket 15. The steel pipe 14 is connected to one side of the U-shape of the U-shaped mounting bracket 15. The motor pipe 122 is fixed by the U-shaped mounting bracket 15 and the L-shaped mounting bracket 16.

The second blade skeleton 114 is connected to the circular tube 111 but does not penetrate the circular tube 111, forming a distributed support structure.

[0035] Both ends of the circular tube 111 are provided with support plates 115 in both the upper and lower directions. One end of the support plate 115 is attached to the outer wall of the circular tube 111, and the other end is connected to the first blade skeleton 113 to disperse the stress when the louver rotates.

[0036] The louver body 11 also includes a double-arc shuttle-shaped panel 116, which covers the outside of the first blade skeleton 113, the support piece 115 and the circular tube 111, and is used to enhance the structural strength and optimize the airflow distribution.

[0037] The reducer is a planetary gear reducer, used to reduce the speed of motor 121 and increase the output torque, so that the louver rotation is smooth.

[0038] The motor tube 122 has an opening 123 at one end near the motor push head 124. The width of the opening 123 is greater than the movement trajectory of the motor push head 124, so as to avoid interference between the motor push head 124 and the motor tube 122 when the motor push head 124 rotates.

[0039] The double-arc shuttle-shaped panel 116 has an arc curvature radius of 50mm~200mm and an arc spacing of 10mm~30mm, which is used to reduce the impact of wind pressure on the louvers while providing sun shading.
