Description

Technical Field

[0001] This invention relates to the field of home furnishing technology, to a curtain device, and more particularly to a novel electric curtain device. Background Technology

[0002] Curtain systems are devices installed on windows to regulate indoor light, improve ventilation, and enhance the interior environment. Their main components include curtains, blinds, and Venetian blind shades. Traditionally, curtain systems are manually operated, requiring users to manually adjust the position or angle of the curtains, blinds, and Venetian blind shades to control their opening and closing.

[0003] For curtain systems, manual and electric drives each have their advantages and disadvantages: manual curtain systems have the advantages of simple structure and low cost, which can reduce the number of components and minimize the complexity of the system, but they are inconvenient to operate; new electric curtain systems are easy and labor-saving to operate, but they have problems such as complex structure and high cost.

[0004] Existing curtain systems are highly specialized, often overemphasizing either the simplicity of manual operation or the convenience of electric operation to meet diverse user needs. Users are forced to choose between these two options, unable to make a smooth transition. Therefore, the industry urgently needs a new curtain system that combines simplicity and ease of operation through scientific structural design, while effectively reducing renovation costs. Summary of the Invention

[0009] The motor housing has a recessed portion, and the motor housing is mounted on the motor mounting base by sliding engagement between the recessed portion and the mounting portion. A motor is installed inside the motor housing, and the power output shaft of the motor protrudes outside the motor housing.

[0010] A power transmission assembly, wherein the power output shaft is connected to a curtain, blind, or Venetian blind via the power transmission assembly.

[0011] Compared with the prior art, the beneficial effects of this technical solution are: a mounting part is provided on the fixed main board, and a recessed part is provided on the motor housing.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer and more explicit, 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 merely illustrative of the invention and are not intended to limit the invention.

[0035] In the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. When a component is referred to as being "fixed to" or "set on" another element, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening component. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Existing curtain systems are highly specialized, often overemphasizing either the simplicity of manual operation or the convenience of electric operation to meet diverse user needs. Users are forced to choose between these two options, unable to make a smooth transition. Therefore, the industry urgently needs a new curtain system that combines simplicity and ease of operation through scientific structural design, while effectively reducing renovation costs.

[0038] like Figure 1 and Figure 2 As shown, in order to solve the above problems, the present invention provides a novel electric curtain device, including a motor mounting base 1, a motor housing 2, and a power transmission component.

[0039] like Figure 3As shown, the motor mounting base 1 is provided with a mounting main board 101, which is mounted on the mounting plane via a main board fixing part. The mounting main board 101 forms a mounting part through a protruding flange 103. The motor housing 2 is provided with a recessed part, which is slidably engaged with the mounting part to be mounted on the motor mounting base 1. A motor is disposed inside the motor housing 2, and the power output shaft of the motor protrudes outside the motor housing 2. The power output shaft is connected to a curtain, blind, or Venetian blind through the power transmission assembly. Specifically, the mounting plane can be a wall or window frame, or other planes.

[0040] Simply separating the power output shaft and the power transmission component allows the curtain device to be converted from electric to manual. Furthermore, the recessed part and the mounting part can be slidably engaged to achieve a detachable connection between the motor housing 2 and the motor mounting base 1, making it very convenient to install or remove the motor housing 2.

[0041] Based on the above structure, the motor housing 2 is mounted on the motor mounting base 1 by sliding engagement between the recessed part and the mounting part. The power output shaft is exposed outside the motor housing 2 and is connected to the curtain, blinds or Venetian blinds through the power transmission component. This makes the curtain device simple in structure and easy to operate, effectively reducing the conversion cost of the curtain device between manual and electric types.

[0042] Two mounting portions and two recessed portions are provided. The two mounting portions are disposed on the fixed main board 101 with a relative interval, and the two recessed portions are disposed on the motor housing 2 with a relative interval.

[0043] Considering that the motor housing 2 and the motor mounting base 1 are slidably engaged through the cooperation of the recess and the mounting part, and that the sliding engagement must occur within a specific track, the recess acts as a track in this technical solution. When the mounting part is fitted into the recess, it moves within the limited range of the recess. Since there are two recesses and two mounting parts, the stability between the motor mounting base 1 and the motor housing 2 is further improved, which helps ensure a secure fastening effect.

[0044] like Figure 5 As shown, the mounting portion includes a support portion 102 and a flange 103. One end of the support portion 102 is connected to the fixed motherboard 101. The flange 103 is formed by extending outward from the end of the support portion 102 away from the fixed motherboard 101. The flange 103 is spaced apart from the fixed motherboard 101, and the flanges 103 of the two mounting portions extend towards each other.

[0045] like Figure 4As shown, the two recessed portions are the first mounting groove 201 and the second mounting groove 202, respectively. The motor housing 2 forms the first mounting groove 201 and the second mounting groove 202 by providing an elongated groove structure along the length direction. The upper openings of the first mounting groove 201 and the second mounting groove 202 are respectively provided with a first limiting plate 203 and a second limiting plate 204. The first limiting plate 203 and the first mounting groove 201 and the second limiting plate 204 and the second mounting groove 202 are respectively provided with disassembly and assembly openings.

[0046] On the motor housing 2, the first mounting groove 201 and the second mounting groove 202 are elongated groove structures with the same width along their length. After the first limiting plate 203 and the second limiting plate 204 are respectively provided above the corresponding parts of the first mounting groove 201 and the second mounting groove 202, a disassembly opening is formed. At this time, the width of the disassembly opening is relatively large, which can be used to fit the flange 103, while the width of the first limiting plate 203 and the second limiting plate 204 is relatively small due to their presence, which can be used to limit the flange 103.

[0047] During installation, after the mounting part is inserted through the disassembly and assembly opening, the mounting part is controlled to slide towards the depth of the first mounting groove 201 and the second mounting groove 202 until the mounting part is fully inserted. Then, it will be fixed in the first mounting groove 201 and the second mounting groove 202 by the first limiting plate 203 and the second limiting plate 204. At this time, the connection between the motor mounting base 1 and the motor housing 2 can be completed.

[0048] Therefore, by forming recesses on the back of the motor housing 2 through the first mounting groove 201 and the second mounting groove 202, and by forming disassembly and assembly openings through the first limiting plate 203 and the second limiting plate 204, the two mounting parts can be inserted into the first mounting groove 201 and the second mounting groove 202 respectively through the disassembly and assembly openings. On the other hand, the first limiting plate 203 and the second limiting plate 204 can ensure effective engagement between the motor mounting base 1 and the motor housing 2. This effectively reduces the difficulty of disassembly and assembly, and installation and disassembly can be completed without the need for additional tools.

[0049] Preferably, the motherboard fixing part includes an oblong mounting through hole and a circular mounting through hole, and the external connector passes through the oblong mounting through hole and the circular mounting through hole to fix the motherboard on the mounting plane. Specifically, the oblong mounting through hole is located at the upper or lower part of the motherboard; correspondingly, the circular mounting through hole is located at the lower or upper part of the motherboard. That is, when the oblong mounting through hole is located at the upper part of the motherboard, the circular mounting through hole is located at the lower part of the motherboard; when the oblong mounting through hole is located at the lower part of the motherboard, the circular mounting through hole is located at the upper part of the motherboard.

[0050] The installation process for the fixed motherboard is as follows: First, pass the external connector (such as a nut) through the circular mounting hole to pre-fix the motherboard to the mounting surface. Pre-fixation means the external connector is inside the mounting surface but not yet fully locked, preventing the motherboard from falling and allowing for angle adjustment. Second, using the external connector in the circular mounting hole as the center, adjust the angle of the motherboard according to the actual situation to ensure it is vertical, meaning the circular and oblong mounting holes are on the same vertical line. Finally, after adjusting the angle, pass the external connector through the oblong mounting hole and lock it in place, simultaneously locking the external connector in the circular mounting hole, completing the installation of the fixed motherboard. At this point, the fixed motherboard is securely mounted on the mounting surface.

[0051] Based on the above technical solution, on the one hand, after setting the oblong and circular mounting through holes on the fixed motherboard, the fixed motherboard can be fixed on the mounting plane in a very simple structure by using external connectors to cooperate with the oblong and circular mounting through holes; on the other hand, since the fixed motherboard is set with circular and oblong mounting through holes, during installation, the external connector in the circular mounting through hole is fixed first, and then the fixed motherboard is adjusted according to the actual situation, so that the fixed motherboard can be adjusted to a horizontal or vertical state, and then fixed.

[0052] like Figure 5 and Figure 6 As shown, an auxiliary side plate 104 is protruding from one side of the fixed motherboard 101, and the protruding direction of the auxiliary side plate 104 is consistent with that of the mounting part.

[0053] In addition to fixing the main board 101 to the mounting plane via the main board fixing part, the auxiliary side plate 104 is also fixed to the mounting plane via the side plate fixing part. That is, the motor fixing device in this technical solution is fixed simultaneously by fixing the main board 101 and the auxiliary side plate 104, which makes the motor fixing device more stable and reliable. Furthermore, the design of the auxiliary side plate 104 being perpendicular to the main board 101 facilitates fixing the auxiliary side plate 104 and the main board 101 to two adjacent walls during installation, saving installation space and improving stability.

[0054] like Figure 5 and Figure 6 As shown, specifically, the auxiliary side panel 104 includes a first side panel and a second side panel that are parallel to each other, and the first side panel and the second side panel are perpendicular to each other with respect to the fixed main board 101. The first side panel is close to the first protruding mounting portion and the second protruding mounting portion, while the second side panel is away from the first protruding mounting portion and the second protruding mounting portion, and a mounting gap 107 is formed between the first side panel and the second side panel.

[0055] Combination Figure 5 and Figure 6 As can be seen, the side plate fixing part includes at least one mounting recess 105 and at least one side mounting through hole 106. The mounting recess 105 is disposed on the first side plate, and the side mounting through hole 106 is disposed on the second side plate. The mounting recess 105 and the side mounting through hole 106 are disposed in a one-to-one correspondence.

[0056] During installation, the external connector passes through the mounting recess 105 and then through the side mounting through hole 106, thereby fixing the side plate fixing part on the mounting plane. It is important to note that when bolts are used as external connectors, the width of the mounting gap 107 is greater than the thickness of the nut, and the external connector is embedded within the mounting gap 107. By providing the mounting gap 107, the external connector can be embedded outside the side mounting through hole 106, thus not affecting the installation and unloading of the motor.

[0057] like Figure 7 and Figure 8As shown, when the power output shaft is connected to the curtain through the power transmission assembly, the power transmission assembly is a drive structure 3. The drive structure 3 includes a drive housing 301, a transmission assembly, and a drive roller 305. Specifically, the drive housing 301 has a receiving cavity for accommodating and installing internal components such as the transmission assembly and the drive roller 305; the transmission assembly includes a power gear 302, a transmission gear 303, and a drive gear 304, which are arranged sequentially from bottom to top and mesh with each other. The power gear 302 is connected to the power output shaft of the motor through a connecting part thereon; the drive roller 305 is coaxially fixed to the drive gear 304, and the portion of the drive roller 305 exposed outside the drive housing 301 abuts against the guide rail. Specifically, the D-shaped cross-section of the power output shaft, through the setting of the D-shaped hole, can simultaneously ensure the fixing effect and the transmission effect.

[0058] The innovation of this technical solution lies in the fact that the power of the motor is transmitted upward through the sequentially arranged and meshing power gear 302, transmission gear 303, and drive gear 304 from bottom to top, thereby controlling the rotation of the drive roller 305. The drive roller 305 abuts against the guide rail through the portion exposed outside the drive housing 301. Therefore, during rotation, the drive roller 305 will move relative to the guide rail due to friction. Thus, by outputting the motor's power to the drive roller 305, and then having the drive roller 305 apply the motor's power to the guide rail, thereby driving the curtain to open and close, this method has the advantages of simple structure and high transmission efficiency.

[0059] like Figure 9 As shown, the drive roller 305 includes a drive roller 306, a drive inner core 307, and a drive shaft 308. The drive roller 306 has a cylindrical structure, and a plurality of internal grooves 309 are provided in the center of the drive roller 306 along the length direction. One end of the drive inner core 307 is provided with a plurality of external protrusions 310, and the external protrusions 310 correspond one-to-one with the internal grooves 309. The drive inner core 307 is disposed in the drive roller 306 through the engagement of the external protrusions 310 and the internal grooves 309. The drive gear 304 is disposed at the other end of the drive inner core 307. A through hole is provided in the center of the drive inner core 307 along the length direction, and the drive inner core 307 passes through this through hole onto the drive shaft 308.

[0060] The drive roller 306 and the drive inner core 307 are integrated into a whole by meshing with corresponding internal grooves 309 and external protrusions 310. This whole is then inserted into the drive shaft 308 through the central through hole of the drive inner core 307 to complete the installation. When the transmission gear 303 is driven, it will cause the whole consisting of the drive roller 306 and the drive inner core 307 to rotate around the drive shaft 308.

[0061] Based on the above structure, especially with the drive gear 304 set on the drive inner core 307, it can effectively receive power from the power output shaft of the motor. At the same time, there is no need to set more gears. Power is directly provided through the drive gear 304 to control the drive roller 306 to rotate around the drive shaft 308 as the central axis, thereby driving the curtain to move.

[0062] like Figure 10 and Figure 11 As shown, the motor housing 2 is also provided with a connection structure, which includes a connection component 205 and an elastic element 206. The connection component 205 is used to connect the drive housing 301 and the guide rail, while the elastic element 206 is used to ensure that the distance between the drive housing 301 and the guide rail is more reasonable.

[0063] The elastic element 206 is disposed on the drive housing 301 of the motor. The elastic element 206 provides enough elastic force to pull the drive housing 301 towards the guide rail. One end of the connecting component 205 is movably disposed on the guide rail, and the other end of the connecting component 205 is disposed on the drive housing 301 via the elastic element 206. A drive roller 305 is disposed on the drive housing 301, located between the drive housing 301 and the guide rail. The drive roller 305 is subjected to the elastic force applied by the elastic element 206 and abuts against the guide rail.

[0064] Based on the above structure, the elastic element 206 continuously applies a spring force to the connecting assembly 205. Under the action of this spring force, the connecting assembly 205 tends to move closer to the guide rail, thereby ensuring that the drive roller 305 and the guide rail are always in close contact. In this way, when the motor drives the drive roller 305, sufficient and continuous friction is generated between the drive roller 305 and the guide rail, thus enabling the electric curtain to operate stably.

[0065] like Figure 10 and Figure 11As shown, the connecting assembly 205 includes a connecting arm 213, a connecting sleeve, and a connecting slider; one end of the connecting arm 213 is movably disposed on the guide slide rail, and the other end of the connecting arm 213 is sleeved in the connecting sleeve. The connecting sleeve and the connecting slider are connected as a whole, and the connecting slider is movably disposed in the drive housing 301 through the elastic element 206.

[0066] The connecting component 205 is movably connected to the guide rail through one end of the connecting arm 213, so that the connecting structure can move horizontally on the track of the guide rail; while the other end of the connecting arm 213 is sleeved in the connecting sleeve, thereby forming a whole with the connecting sleeve and the connecting slider, and achieving connection and fixation with the drive housing 301.

[0067] Specifically, the drive housing 301 has an elastic receiving cavity, and the elastic element 206 and the connecting slider are disposed within the receiving cavity. One end of the elastic element 206 abuts against the top of the receiving cavity, and the other end of the elastic element 206 abuts against the connecting slider. The elastic element 206 applies elastic force to the top of the receiving cavity and to itself. More specifically, the elastic element 206 is a compression spring.

[0068] Preferably, the connecting assembly further includes a side connecting block and a limiting protrusion block, the connecting sleeve and the connecting slider are connected as a whole through the side connecting block, and the limiting protrusion block is formed on the connecting slider; the driving housing is provided with a sliding strip hole and a limiting strip hole, the side connecting block is movably disposed in the sliding strip hole, and the limiting protrusion block is movably disposed in the limiting strip hole.

[0069] The sliding strip hole and the limiting strip hole are elongated through holes opened on the drive housing. While the connecting slider is set in the receiving cavity, the side connecting block and the limiting protrusion are located in the sliding strip hole and the limiting strip hole, respectively. The side connecting block is used to connect with the connecting sleeve through the sliding strip hole to form a whole, and the limiting protrusion is used to cooperate with the limiting strip hole, so that the connecting slider can move more stably along the receiving cavity.

[0070] The process by which the elastic element functions is as follows: the connecting arm is inserted into the connecting sleeve, and the gear adjustment part is locked in place with the gear adjustment buckle. Then, the connecting arm is inserted into a specific position inside the connecting sleeve, so that the drive roller slightly abuts against the guide rail. At this time, the elastic element is in a compressed state, which generates two elastic forces: upward and downward. The downward elastic force is canceled out by the fixed connection between the connecting arm and the connecting sleeve, while the upward elastic force will further lift the drive roller and make it more tightly abut against the guide rail, thus ensuring that the drive roller and the guide rail are always in close contact.

[0071] Based on the above technical solution, the elastic element 206 and the connecting slider are set in the receiving cavity. The restriction of the receiving cavity makes the elastic force direction of the elastic element 206 more clear, which is conducive to pressing the drive roller 305 against the guide rail.

[0072] Preferably, one end of the connecting arm 213 is provided with a gear adjustment part 212, the gear adjustment part 212 including a plurality of stepped protrusions; the connecting sleeve is provided with a gear adjustment buckle, and the connecting arm 213 is disposed on the connecting sleeve by the engagement of the gear adjustment part 212 and the gear adjustment buckle.

[0073] To ensure a good fit between the drive roller 305 and the guide rail, the elastic element 206 plays only an auxiliary role; the main function is achieved through the connecting arm 213. One end of the connecting arm 213 is inserted into the connecting sleeve, and after being pushed in to the appropriate length along the connecting sleeve, the relative position between the connecting arm 213 and the connecting sleeve is fixed by the engagement of the gear adjustment buckle and the stepped protrusion. This allows control over the distance between the drive roller 305 and the guide rail. Therefore, through the engagement of the gear adjustment part 212 and the gear adjustment buckle, the length of the connecting arm 213 can be adjusted as needed, keeping the interaction force between the drive roller 305 and the guide rail within a reasonable range.

[0074] like Figure 12 As shown, when the power output shaft is connected to the louver through the power transmission assembly, the power transmission assembly includes a swing assembly 4 and a blade connecting part 5. One end of the swing assembly 4 is disposed on the power output shaft of the motor, and the other end of the swing assembly 4 is movably connected to the blade connecting part 5. The blade connecting part 5 is detachably disposed on the window blade of the louver. The power output shaft drives the swing assembly 4 to swing, and the swing assembly 4 drives the window blade to open or close through the blade connecting part 5.

[0075] In this technical solution, the motor drives the swing assembly 4 to swing back and forth within a certain angle via the power output shaft, rather than driving the swing assembly 4 to perform a complete circular motion; more figuratively, the trajectory traced by the swing assembly 4 in this technical solution is a fan shape rather than a circle. During operation, the power output shaft drives the swing assembly 4 to swing, and the swing assembly 4 drives the louver slats to open or close via the blade connecting part 5.

[0076] Based on the above technical solution, on the one hand, the motor replaces human power to control the power output shaft to drive the swing component 4 to swing, and the swing component 4 drives the window blades through the blade connecting part 5, thereby controlling the louver to open or close; on the other hand, since the blade connecting part 5 is detachably set on the window blades, it is convenient for users to switch between manual mode and electric mode according to different applicable scenarios, so that this new type of louver can be applied to more scenarios.

[0077] Preferably, the swing assembly 4 is a swing connecting arm, and the swing connecting arm is provided with a swing strip hole along its length direction; the blade connecting part 5 includes a blade connecting block and a blade connecting pin, the blade connecting block is detachably mounted on the window blade at one end, and the blade connecting pin is located at the other end of the blade connecting block; the blade connecting pin passes through the swing strip hole of the swing connecting arm, and the window blade is opened or closed by the blade connecting pin and the blade connecting block during the swinging process of the swing connecting arm.

[0078] Here's a brief description of the structure and working principle of the new type of venetian blind: A motor controls the power output shaft, driving the swing assembly to swing back and forth. Using a vertical line as the center line, the swing connecting arm swings within a 30° range to the left and right of the vertical line. During this process, the blade connecting pin remains within the swing strip hole. As the swing connecting arm swings from one side to the other, the blade connecting pin slides from one end of the swing strip hole to the other due to the squeezing action of the hole. This causes the blade connecting block to move and tilt to different angles. The blade connecting block is fixed to the window slats; when the blade connecting block tilts, it naturally causes the window slats to tilt, thus controlling the opening and closing of the venetian blind. It should be noted that the multiple window slats of the venetian blind are interconnected.

[0079] Based on the above structure, when the power output shaft rotates back and forth, it will drive the swing connecting arm to rotate back and forth within a certain angle with one end as the center. During this process, the swing strip hole will move the blade connecting pin back and forth to control the tilt angle of the blade connection part, thereby controlling the louver to open or close.

[0080] like Figure 14 , Figure 15 and Figure 16 As shown, when the power output shaft is connected to the Venetian blind via the power transmission assembly, the Venetian blind includes multiple slats 6, a slat drive assembly 7, and a rotary transmission shaft 8. The multiple slats 6 are arranged as a whole and are linked together. That is, during the process of controlling the movement of the Venetian blind, the multiple slats 6 will rotate simultaneously, and during the rotation, the rotation angles of the multiple slats 6 are consistent and synchronized.

[0081] The blade drive assembly 7 is connected to the curtain slats 6, and the blade drive assembly 7 drives the curtain slats 6 to rotate. Similar to ordinary Venetian blinds, the blade drive assembly 7 includes components such as screws, gears, and ropes, used to drive multiple curtain slats 6 to rotate, thereby changing the angle of the curtain slats 6.

[0082] One end of the rotary drive shaft 8 is connected to the power output shaft of the motor, and the other end of the rotary drive shaft 8 is connected to the blade drive assembly 7. The rotary drive shaft 8 drives components such as screws, gears, and ropes, thereby causing multiple blind blades 6 to rotate, so as to realize the function of controlling the opening and closing of the Venetian blinds.

[0083] The working process of the motorized Venetian blind in this technical solution is as follows: the user controls the rotation of the motor's power output shaft, which drives the blade drive assembly 7 through the rotation transmission shaft 8, thereby controlling the rotation of the blind blades 6. During the rotation, the spacing between the blind blades 6 changes, thus changing the opening and closing state of the Venetian blind. It has the advantages of high driving efficiency and convenient operation. Specifically, the blind blades are arranged horizontally or vertically to suit different types of blind blades.

[0084] A drive shaft sleeve 9 is provided outside the rotary drive shaft 8. The outer diameter of the rotary drive shaft 8 is smaller than the inner diameter of the drive shaft sleeve 9. The rotary drive shaft 8 is rotatably sleeved inside the drive shaft sleeve 9.

[0085] During the control of the opening and closing of the venetian blinds, the rotary drive shaft 8 needs to rotate multiple times. The rotary drive shaft 8 may get caught on foreign objects, causing malfunctions or even safety hazards. To solve this problem, a drive shaft sleeve 9 is installed around the rotary drive shaft 8. During operation, the rotary drive shaft 8 rotates inside the drive shaft sleeve 9, which can physically isolate the rotary drive shaft 8 from the external environment, thereby improving the safety performance of this device.

[0086] Preferably, the rotary drive shaft 8 is a flexible drive shaft. A flexible drive shaft is a shaft with low rigidity and elasticity, which can be bent freely for transmission. Flexible drive shafts are mainly used to connect two shafts that are not in the same direction to transmit rotational motion and torque, and can flexibly transmit rotational motion and torque to any position. Using a flexible drive shaft as the rotary drive shaft 8 not only ensures effective transmission of rotational motion, but also increases the flexibility of this device.

[0087] like Figure 14 and Figure 15As shown, the transmission shaft sleeve 9 includes a first straight sleeve 901, a first curved sleeve 902, a second straight sleeve 903, a second curved sleeve 904, and a third straight sleeve 905; the first straight sleeve 901, the first curved sleeve 902, the second straight sleeve 903, the second curved sleeve 904, and the third straight sleeve 905 are connected end to end in sequence, and the first straight sleeve 901, the first curved sleeve 902, the second straight sleeve 903, the second curved sleeve 904, and the third straight sleeve 905 form a U-shaped structure.

[0088] Generally, both the blinds and the motor are mounted on the same wall. The blind blade drive assembly 7 faces away from the wall, and the motor's power output shaft also faces away from the wall. This creates a significant obstacle to their connection.

[0089] Based on the above structure, a U-shaped structure is formed by sequentially connecting the first straight sleeve 901, the first curved sleeve 902, the second straight sleeve 903, the second curved sleeve 904, and the third straight sleeve 905. After the transmission flexible shaft is fitted into the transmission shaft sleeve 9, the end near the first straight sleeve 901 is connected to the power output shaft of the motor, and the end near the third straight sleeve 905 is connected to the louver drive assembly 7. This facilitates the installation of the motor, allowing the louver and the motor to be installed on the same wall, thereby saving space and improving the rationality and scientific nature of the overall structure. Preferably, the material of the transmission shaft sleeve is a deformable metal, which allows the user to adjust the shape of the transmission shaft sleeve according to different situations.

[0090] like Figure 5 and Figure 6 As shown, the flange 103 is provided with a plurality of stop slots 108, and the motor housing 2 is provided with an elastic snap-fit ​​assembly 209. Figure 2 As shown, the motor housing 2 is provided with a first limiting strip 207 and a second limiting strip 208. The first limiting strip 207 and the second limiting strip 208 are respectively provided with a first snap-fit ​​hole and a second snap-fit ​​hole, which are respectively connected to the first mounting groove 201 and the second mounting groove 202. The elastic snap-fit ​​assembly 209 is fixedly disposed between the first limiting strip 207 and the second limiting strip 208.

[0091] After the elastic snap-fit ​​assembly 209 is fixedly set between the first limiting strip 207 and the second limiting strip 208, the first elastic arm 210 and the second elastic arm 211 push out the first snap-fit ​​protrusion and the second snap-fit ​​protrusion, and after passing through the first snap-fit ​​hole and the second snap-fit ​​hole, they are embedded in the stop grooves 108 of the two mounting parts on both sides, thereby fixing the relative position between the motor mounting base 1 and the motor housing 2.

[0092] like Figure 13 As shown, the elastic snap-fit ​​assembly 209 includes a first elastic arm 210 and a second elastic arm 211. The ends of the first elastic arm 210 and the second elastic arm 211 are respectively provided with a first snap-fit ​​protrusion and a second snap-fit ​​protrusion. In normal state, the first snap-fit ​​protrusion and the second snap-fit ​​protrusion pass through the first snap-fit ​​hole and the second snap-fit ​​hole respectively and are embedded in the stop grooves 108 of the mounting part on both sides.

[0093] After fitting the motor mounting base 1 and the motor housing 2 together, it is necessary to adjust their relative positions. The specific operation is as follows: apply force to bring the first elastic arm 210 and the second elastic arm 211 closer together. At this time, the first and second locking protrusions will retract accordingly, allowing the mounting parts to move freely within the recesses on the motor housing 2. Then, simply adjust the relative positions of the motor mounting base 1 and the motor housing 2 to the desired state, and then remove the external force applied to the first and second elastic arms 210 and 211. The first and second locking protrusions will then spring back, pass through the first and second locking holes, and embed into the positioning grooves 108 of the two mounting parts, completing the adjustment of the relative positions between the motor mounting base 1 and the motor housing 2.

[0094] like Figure 13 As shown, a gear adjustment component 214 is also movably disposed inside the motor housing 2. The gear adjustment component 214 is movably disposed between the first limiting bar 207 and the second limiting bar 208 via an elastic element 206. The gear adjustment component 214 drives the first elastic arm 210 and the second elastic arm 211 respectively via the first contact arm and the second contact arm.

[0095] Based on the above structure, the first contact arm and the second contact arm on the gear adjustment assembly 214 drive the first elastic arm 210 and the second elastic arm 211 respectively, thereby controlling the first locking protrusion and the second locking protrusion to push into the gear slot 108 or pop out from the gear slot 108, so as to adjust the relative position between the motor fixing seat 1 and the motor housing 2 to accommodate different lengths of beaded chains.

[0096] Combination Figure 6 and Figure 7As can be seen, the gear adjustment section 212 is also provided with a control strip section, which, the first contact arm, and the second contact arm are fixed together to form a whole; the control strip section extends beyond the motor housing 2, making it convenient for the user to drive the movement of the gear adjustment section 212 by controlling the strip section. Preferably, the first contact arm and the first elastic arm 210 are provided with corresponding inclined surfaces, and the second contact arm and the second elastic arm 211 are provided with corresponding inclined surfaces.

[0097] When adjusting the gear using the gear adjustment unit 212, simply press the control bar. This drives the control bar to move the first contact arm and the second contact arm upwards. After contacting the first elastic arm 210 and the second elastic arm 211 respectively, the first and second contact arms continue to apply force. Since each of the first elastic arm 210, the second elastic arm 211, the first contact arm, and the second contact arm has an inclined surface, the mutual contact between these inclined surfaces effectively drives the first elastic arm 210 and the second elastic arm 211, thereby achieving gear adjustment. After the gear adjustment is completed, simply release the force applied to the control bar, and the elastic element 206 will spring the gear adjustment unit 212 back to its original position.

[0098] Compared to existing technologies, the biggest innovation of this invention lies in giving the curtain device greater flexibility. By combining the motor mounting base 1, motor housing 2, and motor 10 in this curtain device, the existing curtains, blinds, or Venetian blinds can be transformed into electric devices through a simple and reasonable structure by simply connecting the corresponding power transmission components according to different situations, greatly improving the flexibility of device modification.

[0099] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
