Description

An electric louver with sunshade adjustment function Technical Field

[0001] This utility model belongs to the field of venetian blind technology, specifically relating to an electric venetian blind with sunshade adjustment function. Background Technology

[0002] Venetian blinds are a type of window that provides privacy and blocks sunlight and ultraviolet rays. Venetian blinds offer numerous advantages and are aesthetically pleasing, commonly used in high-rise buildings. There are two installation methods for Venetian blinds: concealed and surface-mounted. When purchasing Venetian blinds, the size should be measured according to the installation method. Concealed Venetian blinds are suitable for small rooms such as kitchens and bathrooms, while surface-mounted Venetian blinds are more suitable for larger rooms such as living rooms, bedrooms, and studies.

[0003] Traditional shading louvers are separate from ventilation window systems. When shading, the windows need to be closed, which leads to stuffiness. When the windows are open for ventilation, the shading effect is lost. The single-layer glass structure cannot block heat transfer, which increases the air conditioning load in summer. Moreover, when using gear chain drive for large-span windows, the end blades will have angular deviations due to torque attenuation, resulting in uneven shading and high light leakage. Therefore, we propose an electric louver with shading adjustment function. Summary of the Invention

[0004] The purpose of this invention is to provide an electric louver with a sunshade adjustment function, in order to solve the problems mentioned in the background art.

Embodiments

[0026] Please refer to Figures 1-5. The technical solution provided in this embodiment is as follows:

[0027] An electric louver with shading adjustment function includes: a louver structure 1, and a ventilation structure 2 fixedly connected to the back of the louver structure 1.

[0028] The louver structure 1 includes a window frame 101. Multiple connecting shafts 102 are rotatably connected to the surface of the window frame 101. Adjusting blades 103 are fixedly connected to the surface of the connecting shafts 102. Connecting rods 104 are fixedly connected to the surface of the connecting shafts 102. The multiple connecting rods 104 are connected by transmission through a transmission plate 105. Connecting protrusions 111 are fixedly connected to the surface of the transmission plate 105.

[0029] The ventilation structure 2 includes a mounting shell 201 fixedly connected to the back of the window frame 101. A transparent glass 202 is fixedly connected to the inner side of the mounting shell 201. A first ventilation window 203 is rotatably connected to the inner side of the mounting shell 201 and to both sides of the transparent glass 202. A second ventilation window 204 is rotatably connected to the surface of the first ventilation window 203. Through the back-to-back design of the ventilation structure 2 and the louver structure 1, the airflow exchange is maintained when the adjusting blades 103 adjust the light. Combined with the double-layer heat insulation structure of the transparent glass 202, the overall energy saving rate is improved. The planar linkage mechanism of the connecting rod 104 and the transmission plate 105 eliminates the cumulative error of the transmission chain. The arc groove 107 mechanically limits the overshoot and maintains the transmission efficiency.

[0030] Specifically, a guide plate 106 is fixedly connected to one side of the window frame 101. An arc-shaped groove 107 is provided on the surface of the guide plate 106, and a connecting protrusion 111 is slidably connected to the surface of the arc-shaped groove 107.

[0031] In a specific embodiment of this utility model, the guide plate 106 is fixed to the side of the window frame 101, and its arc groove 107 is slidably engaged with the connecting protrusion 111 to convert the linear displacement output by the servo motor 112 into the arc trajectory motion of the connecting protrusion 111, driving the transmission plate 105 to swing. The arc groove 107 provides physical limit to avoid transmission overshoot and cause the angle of the adjusting blade 103 to overshoot, thereby improving the synchronization accuracy.

[0032] Specifically, a threaded rod 108 is rotatably connected to the surface of the window frame 101, and an internal threaded block 109 is threadedly connected to the surface of the threaded rod 108. A sliding groove 110 is provided on the surface of the internal threaded block 109, and a connecting protrusion 111 is slidably connected to the surface of the sliding groove 110.

[0033] In a specific embodiment of this utility model, the threaded rod 108 is driven to rotate by the servo motor 112, and the internal threaded block 109 moves along the axial direction of the threaded rod 108. Its sliding groove 110 is slidably connected to the connecting protrusion 111, which converts the rotational motion of the threaded rod 108 into the linear displacement of the internal threaded block 109. The threaded transmission has a self-locking characteristic and maintains the stability of the blade angle when the power is off.

[0034] Specifically, a servo motor 112 is fixedly connected to the surface of the window frame 101, and the output shaft of the servo motor 112 is fixedly connected to the threaded rod 108.

[0035] In a specific embodiment of this utility model, the output shaft of the servo motor 112 is directly fixed to the threaded rod 108, driving the threaded rod 108 to rotate forward and backward, and driving the connecting protrusion 111 to move through the internal thread block 109.

[0036] Specifically, a movable handle 205 is fixedly connected to the surface of the second ventilation window 204, and a rubber sleeve is fitted on the surface of the movable handle 205.

[0037] In a specific embodiment of this utility model, a movable handle 205 is fixed on the surface of the second ventilation window 204. The user can manually rotate the second ventilation window 204. The rubber sleeve increases frictional resistance and prevents the hand from slipping.

[0038] Specifically, mounting bases 206 are fixedly connected to both the upper and lower sides of the first ventilation window 203, and inserts 207 are slidably connected to the surface of the mounting base 206. A U-shaped block 208 adapted to the insert 207 is fixedly connected to the surface of the mounting shell 201.

[0039] In a specific embodiment of this utility model, the first ventilation window 203 is locked by sliding the insert 207 through the mounting base 206. The insert 207 is inserted into the U-shaped block 208 of the mounting shell 201, and unlocked by sliding in the opposite direction.

[0040] Specifically, a rotating component 209 is rotatably connected to the surface of the second ventilation window 204, and an adjusting knob 210 is rotatably connected to the surface of the rotating component 209. A locking block 211 adapted to the rotating component 209 is fixedly connected to the surface of the first ventilation window 203.

[0041] In a specific embodiment of this utility model, the rotating component 209 is rotated by the adjusting knob 210, and the rotating component 209 is locked into the inner side of the locking block 211.

[0042] Working principle: Servo motor 112 starts and drives threaded rod 108 to rotate. Internal threaded block 109 moves along the axial direction of threaded rod 108. At this time, connecting protrusion 111 slides in sliding groove 110 and pushes transmission plate 105 to move. Transmission plate 105 drives all connecting rods 104 to deflect synchronously. At the same time, connecting shaft 102 rotates and adjusts the angle of all adjusting blades 103. When the blades are horizontal, they completely block the sun. When they are vertical, they maximize the light. At 45°, they balance the light blocking and the field of vision. Pulling the moving handle 205 opens the second ventilation window 204. The adjusting knob 210 drives the rotating part 209 to rotate and locks the rotating part 209 into the inside of locking block 211. Insert block 207 is inserted into the U-shaped block 208 of mounting shell 201 to lock the first ventilation window 203.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
