Motorized window treatment control device, motorized drive unit, and motor mounting bracket

Abstract

The application relates to an electric curtain control device, an electric drive unit and a motor mounting bracket. The motor mounting bracket comprises a fixed mounting part, a vertical supporting part and a motor mounting part. The motor mounting part is arranged on one side of the vertical supporting part. The motor mounting part has a cantilever section, so that the motor mounting part and the vertical supporting part form an L-shaped elastic cantilever structure. When the motor of the electric drive unit and the driving wheel are fixedly mounted on the motor mounting part, the elastic force of the motor mounting part is applied to the driving wheel to force the driving wheel to press the curtain rail. Since the elasticity of the motor mounting bracket itself is utilized, no elastic element needs to be additionally arranged, no corresponding assembly structure needs to be arranged in the electric curtain control device, and the shell structure can be effectively simplified. Moreover, during the general assembly, no elastic element needs to be separately assembled, and only the electric drive unit needs to be assembled, so that the general assembly process of the electric curtain control device is effectively simplified.

Description

Technical Field

[0001] This invention belongs to the field of curtain opening and closing devices, specifically relating to an electric curtain control device, an electric drive unit, and a motor mounting bracket. Background Technology

[0002] With the rapid development of communication and control technologies, smart home systems have also developed rapidly. Within smart home systems, smart curtain systems can automate the control of curtains, opening and closing them according to user-defined times. This overcomes the inconvenience of manually opening and closing curtains and improves user comfort.

[0003] Currently, most smart curtain systems use electric actuators to pull the curtains for automatic opening and closing. The structure of the electric actuator is similar to the curtain control device disclosed in Chinese Utility Model Patent No. CN209058744U. It is mounted on a curtain track to drive the curtains to open and close. The electric curtain control device generally includes a housing assembly with a drive wheel and driven wheels on its front and rear sides. For an inner track, the two driven wheels press against the top surface of the track's bottom wall, while the drive wheel presses upwards against the bottom surface of the track's bottom wall. This combination enables the electric curtain control device to move and assemble with the curtain track. The drive wheel is embedded in the housing assembly and partially protrudes from it. Driven by a power component, the drive wheel rotates, thereby driving the electric curtain control device to move back and forth, thus opening and closing the curtains. In practice, the drive wheel is driven to rotate by a power component. The bottom of the drive wheel is supported within the housing assembly by a corresponding elastic element. This elastic element allows the drive wheel a certain amount of elastic movement in the vertical direction. On the one hand, this allows the electric curtain control device to be installed on curtain tracks of varying thicknesses, expanding its applicability; on the other hand, it helps reduce sliding resistance. The elastic element can specifically be a spring, a sheet, or elastic rubber, etc.

[0004] The drive wheel is elastically supported and assembled in the housing assembly by elastic elements such as springs, sheet metal, or elastic rubber. To meet installation requirements, limiting structures such as protrusions or slots must be set in the housing assembly to fix the elastic elements. In addition, an assembly structure is also required in the housing assembly to assemble the power component. This makes the internal structure of the housing assembly more complex and the manufacturing cost higher. Moreover, the power component, drive wheel, and elastic elements must be assembled separately during assembly, resulting in many assembly steps and low assembly efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a motor mounting bracket to solve the technical problem in the prior art that the need to set up an assembly structure to assemble the power component and the elastic element leads to a complex housing assembly structure. At the same time, this invention also provides an electric drive unit using the above-mentioned motor mounting bracket to solve the technical problem in the prior art that the need to separately assemble the power component and the elastic element in the housing assembly leads to a large number of assembly steps in the electric curtain control device. This invention also provides an electric curtain control device using the above-mentioned electric drive unit.

[0009] Motor mounting section, used to fix and install the motor of the electric drive unit of the electric curtain control device;

[0010] The motor mounting part is located on one side of the vertical support part. The motor mounting part has a cantilever section so that the motor mounting part and the vertical support part form an L-shaped elastic cantilever structure. When the motor and drive wheel of the electric drive unit are fixedly installed on the motor mounting part, the motor mounting part applies an elastic force to the drive wheel to force it to press against the curtain track.

[0011] The beneficial effects are as follows: In the motor mounting bracket provided by this invention, the motor mounting part is located on one side of the vertical support part and has an overhanging section, so that the motor mounting part and the vertical support part form an L-shaped elastic overhanging structure. During assembly, the fixed mounting part is fixedly installed on the housing of the electric curtain control device. When the motor and the drive wheel are fixedly installed on the motor mounting part, since the motor mounting bracket itself forms an elastic overhanging structure, an elastic force can be applied to the drive wheel to force it to press against the curtain track, ensuring reliable clamping. Because the elasticity of the motor mounting bracket itself is utilized, there is no need to set up additional elastic elements, and therefore no need to set up a corresponding assembly structure in the electric curtain control device, which can effectively simplify the housing structure.

[0012] As a further improvement, the motor mounting part is a mounting cylinder, which allows the motor to be tightly fitted and fixed inside.

[0013] The beneficial effects are: the motor mounting part is a mounting cylinder, which facilitates the plug-in assembly of the motor and makes assembly more convenient.

[0015] The beneficial effects are: setting up heat dissipation and weight reduction holes can not only improve heat dissipation performance, but also reduce the weight of the entire motor mounting bracket.

[0016] As a further improvement, the fixed mounting portion extends laterally to form an inverted T-shaped structure with the vertical support portion.

[0019] The beneficial effect is that the corresponding side of the inverted T-shaped structure is an arc-shaped side, which is used to fit the arc-shaped inner wall of the housing of the electric curtain control device, which can optimize the internal assembly of the electric curtain control device and facilitate the miniaturization design of the electric curtain control device.

[0020] As a further improvement, the fixed mounting part, the vertical support part, and the motor mounting part are integrally injection molded.

[0021] The beneficial effects are: one-piece injection molding, which facilitates processing and manufacturing.

[0022] The technical solution of the electric drive unit provided by this invention is: an electric drive unit, comprising:

[0023] The drive wheel is used to rotate and press against the curtain track.

[0024] An electric motor having a motor output shaft that drives a drive wheel to rotate;

[0025] It also includes a motor mounting bracket, which comprises:

[0026] A mounting bracket is used for fixing the electric curtain control device onto its housing.

[0027] A vertical support portion is provided on the fixed mounting portion, extending vertically upward;

[0028] The motor mounting section has the motor fixedly mounted thereon.

[0029] The drive wheel is fixedly mounted on the motor output shaft;

[0030] The motor mounting part is located on one side of the vertical support part. The motor mounting part has a cantilever section so that the motor mounting part and the vertical support part form an L-shaped elastic cantilever structure, thereby applying an elastic force to the drive wheel to force it to press against the curtain track.

[0031] The beneficial effects are as follows: In the electric drive unit provided by this invention, the elastic overhang structure of the motor mounting bracket itself provides the driving wheel with an elastic force that compresses it against the curtain track, ensuring reliable clamping. Since the elasticity of the motor mounting bracket itself is utilized, there is no need to set up additional elastic elements, and therefore no need to set up corresponding assembly structures within the electric curtain control device, effectively simplifying the housing structure. Furthermore, during assembly, since the motor and driving wheel are pre-assembled on the motor mounting bracket to form the electric drive unit, the assembly of the electric drive unit can be completed in advance, and then the entire electric drive unit can be assembled into the inner wall of the electric curtain control device, effectively simplifying the final assembly process.

[0032] As a further improvement, the motor mounting part is a mounting cylinder, which allows the motor to be tightly fitted and fixed inside.

[0033] The beneficial effects are: the motor mounting part is a mounting cylinder, which facilitates the plug-in assembly of the motor and makes assembly more convenient.

[0034] As a further improvement, the mounting cylinder has heat dissipation and weight reduction holes on its wall.

[0035] The beneficial effects are: setting up heat dissipation and weight reduction holes can not only improve heat dissipation performance, but also reduce the weight of the entire motor mounting bracket.

[0036] As a further improvement, the fixed mounting portion extends laterally to form an inverted T-shaped structure with the vertical support portion.

[0037] The beneficial effect is that the inverted T-shaped structure can improve the overall stability of the motor mounting bracket.

[0038] As a further improvement, the corresponding side of the inverted T-shaped structure opposite to the motor mounting part is an arc-shaped side, which is used to fit the arc-shaped inner wall surface of the housing of the electric curtain control device.

[0039] The beneficial effect is that the corresponding side of the inverted T-shaped structure is an arc-shaped side, which is used to fit the arc-shaped inner wall of the housing of the electric curtain control device, which can optimize the internal assembly of the electric curtain control device and facilitate the miniaturization design of the electric curtain control device.

[0040] As a further improvement, the fixed mounting part, the vertical support part, and the motor mounting part are integrally injection molded.

[0041] The beneficial effects are: one-piece injection molding, which facilitates processing and manufacturing.

[0042] As a further improvement, the drive wheel clearance is fitted outside the motor mounting portion.

[0043] The beneficial effect is that the drive wheel clearance sleeve is installed outside the motor mounting part, which can reduce the axial space occupied by the electric drive unit, making the electric drive unit smaller in size.

[0044] As a further improvement, the upper side of the fixed mounting part facing the drive wheel is provided with a clearance recess, which is open along the axial direction of the drive wheel towards the drive wheel, so that the bottom of the end of the drive wheel facing the vertical support part is arranged in the clearance recess.

[0045] The beneficial effects are: by setting a clearance recess on the upper part of the fixed installation part, and by arranging the bottom of the corresponding end of the drive wheel in the clearance recess, the height and axial length space of the electric drive unit can be further reduced, the overall volume of the electric drive unit can be reduced, and the miniaturization of the entire electric curtain control device can be facilitated.

[0048] The electric drive unit is fixedly installed in the housing;

[0049] The electric drive unit includes:

[0057] The drive wheel is fixedly mounted on the motor output shaft;

[0058] The motor mounting part is located on one side of the vertical support part. The motor mounting part has a cantilever section so that the motor mounting part and the vertical support part form an L-shaped elastic cantilever structure, thereby applying an elastic force to the drive wheel to force it to press against the curtain track.

[0059] The beneficial effects are as follows: In the electric curtain control device provided by this invention, the electric drive unit serves as a pre-assembly unit, allowing both the motor and the drive wheel to be pre-installed on the motor mounting bracket. During final assembly, only the motor mounting bracket needs to be fixedly connected to the housing, effectively simplifying the assembly process. Furthermore, the elastic overhang structure of the motor mounting bracket itself provides the drive wheel with an elastic force that compresses it against the curtain track, ensuring reliable clamping. Because the elasticity of the motor mounting bracket itself is utilized, there is no need to install additional elastic elements, and therefore no need to include a corresponding assembly structure within the electric curtain control device, effectively simplifying the housing structure.

[0060] As a further improvement, the motor mounting part is a mounting cylinder, which allows the motor to be tightly fitted and fixed inside.

[0061] The beneficial effects are: the motor mounting part is a mounting cylinder, which facilitates the plug-in assembly of the motor and makes assembly more convenient.

[0062] As a further improvement, the mounting cylinder has heat dissipation and weight reduction holes on its wall.

[0063] The beneficial effects are: setting up heat dissipation and weight reduction holes can not only improve heat dissipation performance, but also reduce the weight of the entire motor mounting bracket.

[0064] As a further improvement, the fixed mounting portion extends laterally to form an inverted T-shaped structure with the vertical support portion.

[0065] The beneficial effect is that the inverted T-shaped structure can improve the overall stability of the motor mounting bracket.

[0066] As a further improvement, the corresponding side of the inverted T-shaped structure opposite to the motor mounting part is an arc-shaped side, which is used to fit the arc-shaped inner wall surface of the housing of the electric curtain control device.

[0067] The beneficial effect is that the corresponding side of the inverted T-shaped structure is an arc-shaped side, which is used to fit the arc-shaped inner wall of the housing of the electric curtain control device, which can optimize the internal assembly of the electric curtain control device and facilitate the miniaturization design of the electric curtain control device.

[0068] As a further improvement, the fixed mounting part, the vertical support part, and the motor mounting part are integrally injection molded.

[0069] The beneficial effects are: one-piece injection molding, which facilitates processing and manufacturing.

[0070] As a further improvement, the drive wheel clearance is fitted outside the motor mounting portion.

[0071] The beneficial effect is that the drive wheel clearance sleeve is installed outside the motor mounting part, which can reduce the axial space occupied by the electric drive unit, making the electric drive unit smaller in size.

[0097] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0098] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0099] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the term "provided with" should be interpreted broadly. For example, the object "provided with" can be a part of the main body, or it can be separately arranged from the main body and connected to the main body. This connection can be a detachable connection or a non-detachable connection. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0100] The present invention will be further described in detail below with reference to the embodiments.

[0101] The electric curtain control device provided by this invention is used to install on a curtain track to open and close the curtains, achieving intelligent control of the curtains. For example... Figure 1 The motorized curtain control device typically includes a housing 1 and a drive mechanism. This drive mechanism works with the curtain track. In practice, the drive mechanism is not entirely the same for different types of curtain tracks. For example, for interior curtain tracks, the drive mechanism may be as follows: Figure 1The structure of the inner track includes a central driving wheel 2 and two driven wheels 3 on the front and rear sides. The driving wheel 2 is used to press against the bottom surface of the bottom wall of the inner track, while the two driven wheels 3 are located inside the inner track and press against the top surface of the bottom wall of the track. The driving wheel and driven wheels are clamped together, and movement is achieved when the driving wheel rotates. For the outer track, the driving mechanism also includes a driving wheel and driven wheels. The driving wheel presses against the bottom surface of the track, while the driven wheels can adopt a U-shaped structure to press against the bottom rims on both sides of the outer track. For the rod track, the driving mechanism includes a driving wheel and a driven hook. The driving wheel presses against the bottom surface of the track, and the driven hook is hooked onto the rod track. The driven hook is generally equipped with a rolling sleeve to roll against the rod track. The rotation of the driving wheel drives the electric curtain control device to move back and forth along the rod track.

[0102] As can be seen from the above description, regardless of the type of electric curtain control device, it is equipped with a drive wheel. The drive wheel protrudes upward from the housing and is driven by a motor powered by a battery. Moreover, an electronic control component is usually installed inside the housing. When in use, a control signal can be sent via a remote controller. The electronic control component receives the signal and controls the motor to start, rotate forward, rotate backward, or stop. The drive wheel rotates forward or backward to open or close the curtain.

[0103] For motorized curtain control devices, in order to adapt to the versatility of curtain tracks of different thicknesses within a small range, and also to ensure that the curtain track is pressed firmly, the drive wheel is usually subjected to elastic force to press against the curtain track. In existing technologies, additional elastic elements such as springs and sheet springs are usually added. This requires the addition of a limiting structure inside the housing, which not only complicates the internal structure of the housing but also increases the assembly process. To address this problem, the present invention adopts a novel motor mounting bracket that provides elastic force to the motor itself. The drive wheel is fixedly assembled with the motor output shaft, so that the motor mounting bracket can apply elastic force to the drive wheel, which can also ensure that the drive wheel reliably presses against the curtain track.

[0104] In fact, such as Figure 3 and Figure 4 As shown, the drive wheel 2, motor 6 and motor mounting bracket 4 are pre-assembled together to form an electric drive unit, wherein the motor 6 is fixedly mounted on the motor mounting bracket 4, and the motor 6 has a motor output shaft 61, which is fixedly assembled with the drive wheel 2.

[0105] When assembling the electric curtain control device, such as Figure 2As shown, the electric drive unit is fixedly installed inside the housing. The motor mounting bracket 4 is fixedly connected to the housing 1 by fastening screws. The driving wheel 2 and the driven wheel 3 cooperate to achieve rolling assembly with the corresponding curtain track. The motor mounting bracket 4 provides elastic force to the driving wheel 2 through the motor 6 to ensure that the driving wheel is reliably pressed against the curtain track.

[0106] like Figure 5 and Figure 6 As shown, the motor mounting bracket 4 includes a fixed mounting part 41, a vertical support part 42, and a motor mounting part 43. The fixed mounting part 41 is used to fix and assemble with the housing of the electric curtain control device. The vertical support part 42 is provided on the fixed mounting part 41 extending vertically in opposite directions. The motor mounting part 43 is used to fix and assemble the motor. Here, the motor mounting part 43 is located on one side of the vertical support part 42, and the motor mounting part 43 has an overhang section so that the motor mounting part 43 and the vertical support part 42 form an L-shaped elastic overhang structure, that is, the motor mounting part 43 is relatively overhanging on the side of the vertical support part 42. The fixed mounting part 41 is located on the lower side of the vertical support part 42. When the fixed mounting part 41 is fixedly assembled with the housing, the elastic overhang structure formed by the motor mounting part 43 provides sufficient elastic force to the motor and the drive wheel, thereby forcing the drive wheel to effectively press against the curtain track.

[0107] In use, the motorized curtain control device is installed on the curtain track. Moving along the track, it opens and closes the curtains by pushing the curtain hangers. Alternatively, if the motor can be remotely controlled to rotate in both directions, a single motorized curtain control device can drive the curtains. If the motor can only rotate in one direction, a pair of motorized curtain control devices can be configured to control the opening and closing of the curtains.

[0108] The motor mounting bracket provided by this invention is an elastic cantilever structure, which provides elastic low-pressure support for the electric drive unit, ensuring that the drive wheel can be effectively pressed against the curtain track. It can adapt to curtain tracks of varying thicknesses within a small range, ensuring the versatility of the electric curtain control device. Furthermore, the electric drive unit is a pre-assembled unit. Since the motor mounting bracket itself provides elastic force to the motor and drive wheel, there is no need for separate elastic elements, eliminating the assembly structure and process of elastic elements. During overall assembly, only the fixed connection between the mounting part and the housing needs to be considered. This not only effectively simplifies the housing structure but also simplifies the overall assembly process and significantly improves overall assembly efficiency.

[0109] Typical embodiment 1 of the implementation of the electric curtain control device:

[0110] like Figure 1 and Figure 2As shown, the electric drive unit, which is formed by pre-assembling the motor mounting bracket 4, the motor and the drive wheel 2 together, is fixedly installed on the corresponding inner wall of the housing 1. The motor is powered by the battery 5, and the motor drives the drive wheel 2 to rotate, and cooperates with the driven wheels 3 located on the front and rear sides of the drive wheel 2 to roll with the inner I-shaped track.

[0111] For the motor mounting bracket 4, its fixed mounting part 41, vertical support part 42 and motor mounting part 43 are integrally injection molded. Specifically, it can be injection molded using ABS+PC (commonly known as ABS plus polycarbonate) material, which is convenient for molding. At the same time, it can form an elastic cantilever structure through the L-shaped structure, and can also ensure the strength of each part of the motor mounting bracket, so as to achieve fast assembly with the shell and fixed assembly with the motor.

[0112] like Figure 5 and Figure 6 As shown, the mounting portion 41 extends laterally to form an inverted T-shaped structure with the vertical support portion 42, thereby improving support stability. Fastening mounting holes 46 are provided on the mounting portion 41 on opposite sides of the vertical support portion 42, facilitating the use of fastening screws to securely assemble the mounting portion 41 to the housing.

[0113] Furthermore, to accommodate the arc-shaped sidewalls of the casing, such as Figure 6 , Figure 10 and Figure 11 As shown, the inverted T-shaped structure has an arc-shaped side 48, which is adapted to fit the arc-shaped inner wall of the housing of the electric curtain control device. In fact, because the housing forms an upward-contracting shape, the arc-shaped side 48 gradually slopes upwards towards the drive wheel 2. The arc-shaped side 48 only needs to fit the inner wall of the housing, and the drive wheel 2 is also sloped upwards; the arc-shaped side only needs to fit the inner wall of the housing.

[0114] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the motor mounting part 43 is specifically a mounting cylinder, and the motor 6 is correspondingly and tightly fitted and fixed inside the mounting cylinder, realizing the fixed assembly of the motor 6 and the motor mounting part 43. Since the fixed connection is achieved by tight-fitting insertion, the inner circumferential surface of the mounting cylinder must match the shape of the outer circumferential surface of the motor 6. Designing the motor mounting part as a cylinder facilitates the tight-fitting insertion and fixing of the motor, which can further simplify the assembly process.

[0115] To improve heat dissipation and weight reduction, heat dissipation and weight reduction holes 45 are provided on the wall of the mounting cylinder, and these holes 45 are distributed around the circumference of the mounting cylinder.

[0116] Furthermore, the motor 6 is tightly fitted inside the cylindrical motor mounting part 43 for easy wiring, such as... Figure 6 and Figure 9 As shown, a wiring groove 47 is provided on the motor mounting bracket 4. The wiring groove 47 is connected to the inner cavity of the mounting cylinder. The wiring groove 47 extends in the vertical direction and has an open structure at the bottom, which facilitates the introduction of wires into the inner cavity of the mounting cylinder through the wiring groove. The wires can be connected to the electrical control component so that the electrical control component can control whether to supply power to the motor.

[0117] It should be noted that the structure of motor 6 here is as follows: Figure 7 As shown, it can be purchased directly from the market. A bracket is fixed to the corresponding end of the housing of motor 6, and a motor output shaft 61 is provided on the bracket. Furthermore, a gear transmission mechanism is also provided on the bracket so that the rotating shaft of motor 6 can drive the motor output shaft 61 through the gear transmission mechanism. This is prior art and will not be described in detail here.

[0118] In this embodiment, as Figure 9 As shown, the main body of the motor 6 is tightly fitted into the mounting cylinder, and the motor output shaft 61 is located outside the mounting cylinder. The motor output shaft 61 is fixedly assembled with the drive wheel 2 so that the drive wheel can be driven to rotate by the motor output shaft 61. Specifically, the drive wheel 2 includes a rigid bushing 21 and a flexible bushing 22. The rigid bushing 21 is fixedly assembled with the motor output shaft 61, and the rigid bushing 21 is loosely fitted outside the mounting cylinder. The flexible bushing 22 is a rubber sleeve that can be tightly fitted onto the rigid bushing 21 and rotate synchronously with the rigid bushing 21.

[0119] It should be noted that in this embodiment, the drive wheel 2 is fitted onto the mounting sleeve with a reverse clearance relative to the outward extension direction of the motor output shaft 61. In order to further reduce the overall size of the electric drive unit, a clearance recess 44 is provided on the upper side of the fixed mounting part 41 facing the drive wheel 2. The clearance recess 44 is open on the side facing the drive wheel along the axial direction of the drive wheel, so that the bottom of the end of the drive wheel 2 facing the vertical support part 42 can be arranged in the clearance recess 44. This reduces the volume of the entire electric drive unit in both the vertical height direction and the length direction of the drive wheel axial direction, which is suitable for the miniaturization design requirements of the curtain controller.

[0120] Because the outer circumference of the drive wheel 2 is cylindrical, the bottom surface of the avoidance recess 41 is arc-shaped to match it. The circumference of the arc-shaped bottom surface is concentric with the circumference of the cylindrical outer circumference, and the radius of the circumference of the arc-shaped bottom surface is larger than the radius of the circumference of the cylindrical outer circumference.

[0121] Specific embodiment 2 of the electric curtain control device provided by the present invention:

[0122] The main difference between this embodiment and Embodiment 1 is that, in Embodiment 1, a clearance recess is provided on the fixed mounting portion, which reduces the overall volume of the electric drive unit. In this embodiment, due to the larger internal space of the housing, the drive wheel is located entirely above the fixed mounting portion; therefore, it is not necessary to provide a clearance recess on the upper side of the fixed mounting portion.

[0123] Specific embodiment 3 of the electric curtain control device provided by the present invention:
