Description

Technical Field

[0001] This invention relates to the field of electric Venetian blinds, and more particularly to a silent and windproof Venetian blind. Background Technology

[0002] Traditional Venetian blinds require manual operation by pulling a lifting strap to control the overall up and down movement of the blinds, and manual operation by pulling a ladder rope to control the rotation angle of the slats when adjusting the light. Therefore, to improve the ease of operation of Venetian blinds, motorized Venetian blinds can be used, which utilize a motor and drive mechanism to achieve remote control of the blinds with high precision.

[0003] During operation, the motor runs and drives the roller to rotate, and the rope winding device on the roller realizes the lifting belt to be wound up and the ladder rope to flip the blades.

[0004] Existing motorized Venetian blinds are prone to noise during use, partly due to the slats swaying and making collision noise, and partly due to the operating noise of the motor and rope winding mechanism, which affects the user experience of motorized Venetian blinds. Summary of the Invention

[0005] The purpose of this invention is to provide a silent and windproof Venetian blind to solve the problems of poor windproof effect and high operating noise during the use of electric Venetian blinds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a silent and windproof venetian blind, comprising: The upper rail has a motor mounting cavity. The drive assembly includes a drive motor, a rope winder, a lifting belt, and a ladder rope. The drive motor is fixedly installed in the motor mounting cavity. The rope winder includes a housing, a shaft, a drum, and a tilting module. The housing is fixedly installed in the motor mounting cavity. The shaft passes through the housing and one end of the shaft is connected to the output end of the drive motor. The drum and the tilting module are both sleeved on the shaft. The lifting belt is wound on the drum. The bottom end of the lifting belt passes through several blades and is connected to the bottom rail. Ladder ropes are symmetrically arranged on both sides of the blades. The top of the ladder ropes is fixedly connected to the tilting module. A connecting rope is provided on the upper and lower sides of each blade. The ends of the connecting ropes are fixedly installed on the ladder ropes. The top of the wire rope is fixedly installed on the upper rail, and the bottom of the wire rope passes through several blades and the bottom rail before being connected to the counterweight. The housing has two bearings arranged in parallel on both sides. The outer ring of the bearing is fixedly installed on the housing, and the inner ring of the bearing is fixedly installed on the reel.

[0007] As a further description of the above technical solution: The blade is equipped with a blade connecting buckle, and the lifting strap is threaded through the blade connecting buckle. The end of the blade connecting buckle is equipped with a guard edge, which contacts the surface of the blade. A groove is provided on the surface of the guard edge facing the blade, and the connecting rope is clamped in the groove.

[0008] As a further description of the above technical solution: The bottom of the lifting belt is equipped with a connecting sleeve, through which the connecting rod passes. The bottom rail is equipped with a bottom rail connecting buckle, and the connecting rod is rotatably mounted on the bottom rail connecting buckle.

[0009] As a further description of the above technical solution: The upper rail surface is equipped with a removable front cover, which extends from the lower side of the front cover to form a light-shielding strip.

[0010] As a further description of the above technical solution: The back of the front cover has two first fastening edges arranged in opposite directions. The surface of the upper rail has a second fastening edge for engaging with the first fastening edges. Symmetrically arranged baffles are provided at both ends of the upper rail.

[0011] As a further description of the above technical solution: Sound insulation cotton is fixedly installed on the back of the front cover.

[0012] As a further description of the above technical solution: The top of the front cover has a weatherstripping mounting groove for mounting weatherstripping.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a drive assembly is installed inside the motor mounting cavity of the upper rail of the Venetian blind to achieve electric control of slat lifting and light adjustment. When the drive motor drives the rope winder's shaft, the bearings on the winder's housing ensure smooth rotation and reduce noise. The lifting belt uses a strip material instead of traditional rope, further improving smooth and quiet slat lifting. Furthermore, steel wire ropes are used to position the slats, preventing swaying during use and providing good wind protection, thus achieving a quiet and windproof Venetian blind.

[0014] 2. In this invention, the front cover is detachably installed by fastening the first fastening edge on its back to the second fastening edge on the surface of the upper rail. Furthermore, the cavity formed by the second fastening edge on the upper rail surface and the baffle can accommodate sound-absorbing cotton from the back of the front cover, further isolating the noise from the motor and winding mechanism within the upper rail, thus achieving quiet operation of the Venetian blinds. In addition, the lower side of the front cover extends beyond the upper rail to form a light-blocking strip, effectively improving the light-blocking effect of the Venetian blinds.

The drive motor 21 is fixedly installed in the motor mounting cavity. The rope winder 22 includes a housing 221, a shaft 222, a drum 223, and a flipping module 224. The housing 221 is fixedly installed in the motor mounting cavity. The shaft 222 passes through the housing 221, and one end of the shaft 222 is connected to the output end of the drive motor 21. The drum 223 and the flipping module 224 are both sleeved on the shaft 222. The lifting belt 23 is wound around the drum 223, and the bottom end of the lifting belt 23 passes through several [unclear - possibly referring to a specific component or module]. The bottom rail 4 is connected to the blade 3. The blade is 360mm wide and the two lifting straps are of the same length to ensure that the two ends of the curtain are horizontal. When the lifting straps rotate and are lifted in the groove of the roller 223, they do not deviate or break. The blade 3 is provided with symmetrical ladder ropes 24 on both sides. The top of the ladder ropes 24 is fixedly connected to the flip module 224.
