Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and in particular to a motor concealment structure for electric curtains. Background Technology

[0002] Motorized blinds are controlled wirelessly via a motor. They can be categorized into built-in and external types based on installation. Depending on the operating mechanism and decorative effect, motorized blinds are further divided into series such as motorized opening and closing blinds, motorized lifting blinds, motorized skylight blinds (outdoor and indoor motorized skylights), motorized sunshades, and motorized awnings. Specific examples include Venetian blinds, roller blinds, Roman blinds, sheer blinds, pleated blinds, and honeycomb blinds.

[0003] A search revealed that application number CN202120938074.5 discloses an intelligent curtain system, aiming to overcome the problem that existing electric roller blind-type intelligent curtains cannot adjust the light transmittance when the curtain completely blocks the window. This system provides an intelligent curtain system that utilizes double-layer curtain material, using a single layer when higher light transmittance is needed and a double layer when lower light transmittance is required. The system includes a curtain body and a control circuit. The curtain body includes a first roller, a second roller, a first curtain fabric, a second curtain fabric, a first servo motor, a second servo motor, and a mounting base. The first servo motor drives the first roller to rotate. The first roller has a strip-shaped hole extending along its axial direction. The first curtain fabric is wrapped around the outside of the first roller, and edging strips are provided along both sides of the first curtain fabric. The second roller is rotatably installed inside the first roller. The second servo motor is located at one end of the first roller and drives the second roller to rotate.

[0004] However, the drive motor of the aforementioned electric curtain is an externally mounted structure. Since electric curtains are often installed outdoors, the protective effect of the drive motor is greatly reduced, and the installation method of this drive motor and its roller makes subsequent disassembly and maintenance inconvenient.

[0005] To address this, a motor concealment structure for electric curtains is proposed, which has the advantages of motor concealment and convenient maintenance, thereby solving the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a motor concealment structure for electric curtains.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a motor concealment structure for electric curtains, comprising a housing and a curtain fabric. A left end cover is installed on the left end of the housing by screws, and a mounting sleeve is welded to the surface of the left end cover. A servo motor is interference-connected inside the mounting sleeve, and a roller is fixed to the output end of the servo motor by a coupling. The curtain fabric is wound around the surface of the roller, and a counterweight strip is fixed to the bottom end of the curtain fabric through the housing. A right end cover is fixedly installed on the right end of the housing by screws. A shaft seat is rotatably installed on the end of the roller away from the servo motor, and the surface of the shaft seat is fixedly connected to the right end cover by screws.

[0008] As a further description of the above technical solution: an installation strip is welded inside the housing, and multiple T-shaped posts are installed at equal intervals on the surface of the installation strip. A set of springs and anti-loosening pry plates are respectively fitted on the surface of each T-shaped post, and the springs on the T-shaped posts abut against the anti-loosening pry plates. The inclined part at the bottom end of the anti-loosening pry plate is set towards the drum.

[0009] As a further description of the above technical solution: two mounting ears are symmetrically welded to the bottom of the housing, and through holes are opened on the surface of both mounting ears.

[0010] As a further description of the above technical solution: two limiting rings are fixed on the surface of the roller, and the distance between the two limiting rings is greater than the width of the curtain.

[0011] As a further description of the above technical solution: the bottom surface of the housing has a strip-shaped opening, and the length of the strip-shaped opening is greater than the width of the curtain, while the length of the counterweight strip is less than the length of the strip-shaped opening.

[0012] As a further description of the above technical solution: the size of the inner space of the mounting sleeve is adapted to the size of the servo motor, and the space between the mounting sleeve and the servo motor is filled with sealant.

[0013] This utility model has the following beneficial effects:

[0014] In this utility model, a left end cover, a mounting sleeve, a servo motor, a drum, and a right end cover are provided on the housing. Since the left end cover and the right end cover are respectively fixed to the openings at both ends of the housing with screws, and the left end cover is connected to the servo motor through the mounting sleeve, and the right end cover is connected to the shaft seat at the tail of the drum with screws, this installation method allows the servo motor to be concealed in the housing, providing a shielding and protective structure for the servo motor compared with the existing external installation method. On the other hand, the entire assembly can be disassembled by removing the right end cover and the shaft seat screws at the tail of the drum, which is convenient for later maintenance.

[0015] In this invention, an installation strip, an anti-loosening lever, a T-shaped post, and a spring are provided. The installation strip is fitted with a T-shaped post and a spring, and the spring is elastically connected to the anti-loosening lever. The inclined end of the anti-loosening lever extends towards the location of the roller, giving it the characteristic of elastic extension and retraction under the action of the spring. As the roller winds up the curtain, the overall diameter of the roller increases. The inclined end of the anti-loosening lever elastically contacts the curtain being wound on the roller, and during the winding stage, it combs the curtain, achieving efficient winding and preventing localized wrinkles or overall loosening of the curtain during the winding stage.

[0022] According to an embodiment of the present invention, a motor concealment structure for electric curtains is provided.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3As shown, a motor concealment structure for an electric curtain according to an embodiment of the present invention includes a housing 1 and a curtain 2. A left end cover 5 is installed on the left end of the housing 1 by screws, and a mounting sleeve 6 is welded to the surface of the left end cover 5. A servo motor 7 is interference-connected inside the mounting sleeve 6, and a roller 8 is fixed to the output end of the servo motor 7 by a coupling. The curtain 2 is wound around the surface of the roller 8, and a counterweight 3 is fixed to the bottom end of the curtain 2 through the housing 1. A right end cover 10 is fixedly installed on the right end of the housing 1 by screws. A shaft seat is rotatably installed on the end of the roller 8 away from the servo motor 7, and the surface of the shaft seat is fixedly connected to the right end cover 10 by screws. The housing 1 is made of stainless steel, and openings are respectively opened at both ends of the housing 1. A control circuit is also provided on the housing 1 corresponding to the servo motor 7. The control circuit includes a remote control module, a motor control module, a light sensor, a controller, and a power supply. The light sensor is connected to the controller, the remote control module is connected to the controller, the motor controller is connected to the controller and the servo motor 7, and the power supply is connected to the controller and the servo motor 7 to realize intelligent control.

[0024] In one embodiment, an installation strip 11 is welded inside the housing 1, and multiple T-shaped posts 14 are equidistantly installed on the surface of the installation strip 11. Each T-shaped post 14 is fitted with a set of springs 15 and anti-loosening boards 12, and the springs 15 on the T-shaped posts 14 abut against the anti-loosening boards 12. The inclined part at the bottom of the anti-loosening boards 12 is set towards the drum 8. With this structure, as the drum 8 winds up the curtain fabric 2, the overall diameter of the drum 8 after winding up the curtain fabric 2 increases. The inclined end of the anti-loosening boards 12 is elastically connected to the curtain fabric 2 wound on the drum 8 and combs the curtain fabric 2 during the winding stage, achieving the effect of efficient winding of the curtain fabric 2 and preventing the curtain fabric 2 from wrinkling locally or becoming loose overall during the winding stage.

[0025] In one embodiment, two mounting ears 4 are symmetrically welded to the bottom of the housing 1, and both mounting ears 4 have through holes on their surfaces. The mounting ears 4 facilitate the installation of the housing 1.

[0026] In one embodiment, two limiting rings 9 are fixed on the surface of the roller 8, and the distance between the two limiting rings 9 is greater than the width of the curtain 2. The setting of the two limiting rings 9 ensures the regularity of the curtain 2 winding.

[0027] In one embodiment, the bottom surface of the housing 1 has a strip-shaped opening 13, and the length of the strip-shaped opening 13 is greater than the width of the curtain 2. The length of the counterweight 3 is less than the length of the strip-shaped opening 13. The curtain 2 can easily extend out of the housing 1 through the strip-shaped opening 13, and the counterweight 3 can pass through the strip-shaped opening 13 and enter the housing 1, which facilitates the subsequent disassembly of the roller 8.

[0028] In one embodiment, the size of the inner space of the mounting sleeve 6 is adapted to the size of the servo motor 7, and sealant is filled between the mounting sleeve 6 and the servo motor 7. The sealant is used to reinforce the interference fit, thereby increasing the firmness of the servo motor 7 installation and making it less prone to loosening.

[0029] Working principle:

[0030] In use, the servo motor 7 is first started by the controller to rotate forward and backward, which causes the servo motor 7 to drive the drum 8 at its output end to rotate forward and backward, so that the curtain 2 wound on the drum 8 is wound up and down, achieving the purpose of winding up and down the curtain 2. As the drum 8 winds up the curtain 2, the overall diameter of the drum 8 after winding up the curtain 2 increases. The inclined end of the anti-loosening plate 12 is elastically connected to the curtain 2 wound up on the drum 8, and combs the curtain 2 during the winding stage, achieving the effect of efficient winding up of the curtain 2, and preventing the curtain 2 from wrinkling locally or becoming loose overall during the winding stage. When it is necessary to disassemble the servo motor 7 and the drum 8, the whole assembly can be disassembled by removing the right end cover 10 and the screws on the tail shaft seat of the drum 8, which is easy for later maintenance.
