Description

Technical Field

[0001] This application relates to the field of electric curtain technology, and more particularly to drive devices and winding mechanisms. Background Technology

[0002] In existing electric curtain drive mechanisms, dual motors are typically used to drive the reel separately to control the raising and lowering of the middle and lower rails.

[0003] In related technologies, when setting up a motorized curtain drive mechanism, the power supply and motor are usually placed at opposite ends of the track and connected by a long wire. To meet the needs of mass production, the length of the connecting wire is usually customized according to the largest size of the curtain (e.g., 3 meters). However, when this drive mechanism is applied to small-sized curtains (e.g., 1 meter), the excessively long wire needs to be folded or tied in the narrow space inside the track, affecting the neatness of the product and easily causing interference between the wire and the rotating moving parts inside the track (e.g., entanglement or scratching). This can lead to abnormal noises during the operation of the motorized curtain, affecting the user experience and even posing safety hazards. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] In related technologies, when setting up a motorized curtain drive mechanism, the power supply and motor are usually placed at opposite ends of the track and connected by a long wire. To meet the needs of mass production, the length of the connecting wire is usually customized according to the largest size of the curtain (e.g., 3 meters). However, when this drive mechanism is applied to small-sized curtains (e.g., 1 meter), the excessively long wire needs to be folded or tied in the narrow space inside the track, affecting the neatness of the product and easily causing interference between the wire and the rotating moving parts inside the track (e.g., entanglement or scratching). This can lead to abnormal noises during the operation of the motorized curtain, affecting the user experience and even posing safety hazards.

[0022] To address the aforementioned issues, this application provides a driving device that integrates the power supply and driving components into a compact design, effectively eliminating the problem of long wires required due to separate power supply, improving the internal cleanliness of the product, and reducing the risk of wires tangling or scratching with rotating moving parts within the track.

[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the structure of the driving device shown in the embodiments of this application; Figure 2 This is another structural schematic diagram of the driving device shown in the embodiments of this application; Figure 3 This is another schematic diagram of the drive device shown in the embodiments of this application.

[0025] See Figures 1 to 3 The drive device of this application includes: a housing 110, at least two drive components 120 and a control component 130.

[0026] The housing 110 has a hollow interior. At least two output ports 111 are provided at the rear end of the housing 110. The output ports 111 are used to connect to a drive shaft, thereby enabling the winding module to operate via the drive shaft. An installation opening 112 is provided at the front end of the housing 110.

[0027] The drive assembly 120 has an output end and a connection end, and at least two drive assemblies 120 are arranged in parallel within the housing 110. The output ends of the two drive assemblies 120 are respectively aligned with at least two output ports 111, so that the drive shaft can directly pass through the output ports 111 and connect to the output end of the drive assembly 120, thereby forming the shortest power transmission path. The drive assembly 120 can be a combination of a motor and a reducer. For example, the drive assembly 120 can be a miniature tubular motor.

[0028] The control component 130 is used to control the operation of the overall drive unit. The control component 130 may include a power control unit 131 and an end cover control unit 132. The power control unit 131 is housed within the housing 110 through a mounting opening 112 and is located on the same side of at least two drive components 120. That is, the power control unit 131 is arranged adjacent to the drive components 120. The end cover control unit 132 abuts against the mounting opening 112. The end cover control unit 132 is mainly used to control the overall operation of the drive unit; for example, the end cover control unit 132 may be equipped with corresponding control buttons or an interactive interface to form an operation panel function.

[0029] Thus, by utilizing the installation opening 112 as both the assembly entrance for the drive assembly 120 and the control assembly 130, and forming a sealed interface through the end cover control section 132, an integrated design structure is formed, so that the power supply line of the drive assembly is completely built into the housing 110, eliminating the need to lay wires in the external track space.

[0030] The power control unit 131 includes a power control board (not shown in the figure), which is electrically connected to at least two drive components 120. It is understood that the power control board can integrate power management circuits such as AC-DC conversion circuits and overload protection circuits, thereby achieving a compact circuit layout.

[0031] In the drive device of this application, an integrated power supply structure is set up inside the drive device through a common housing design, which shortens the power supply line to the inside of the housing. This avoids the limitation of installation position caused by the independent external placement of the power supply module in the prior art, and can effectively eliminate the redundancy of wires inside the track, avoiding motion interference problems caused by wire folding.

[0032] Figure 4This is a schematic diagram of the structure of the fixed base in the driving device shown in the embodiments of this application.

[0033] Please see also Figure 4 In some embodiments, a fixing base 113 is further provided at the rear end of the housing 110. The fixing base 113 has at least two fixing portions 1131 corresponding to at least two drive components 120. The same end of each of the at least two drive components 120 is fixed to one of the at least two fixing portions 1131, thereby limiting and fixing the at least two drive components 120. It should be understood that the number of fixing portions 1131 on the fixing base 113 corresponds to the number of drive components 120; that is, the output end of one drive component 120 is fixed to a fixing portion 1131 and aligned with an output port 111.

[0034] Each fixing part 1131 can be provided with a fixing slot that matches the shape of the output end of the drive assembly 120. It should be understood that each fixing slot corresponds to one drive assembly 120, meaning different drive assemblies 120 are fixed in different fixing slots. Furthermore, the fixing slots of different fixing parts 1131 are isolated from each other, thereby reducing interference between different drive assemblies 120 during operation. The spacing between the fixing slots of different fixing parts 1131 can be adjusted according to the size of the drive assembly.

[0035] The output port 111 can correspond to the fixing part 1131. That is, the output port 111 can be set on the fixing part 1131 of the fixing base 113, and the fixing slot of the fixing part 1131 and the output port are coaxially designed. In this way, multiple drive components 120 form an integral mounting structure through the shared fixing base 113. During assembly, the components only need to be pushed into the corresponding fixing part 1131 to complete the positioning, without the need to adjust the position of each one individually.

[0036] In some embodiments, the drive device further includes a limiting component 140. The limiting component 140 is primarily used to partially limit and fix at least two drive components 120. During assembly, all drive components 120 can be pre-limited and fixed by the limiting component 140 before being assembled simultaneously, thereby further improving the assembly efficiency of the drive device.

[0037] The limiting component 140 may include a first limiting seat 141 and a second limiting seat 142. The first limiting seat 141 is sleeved on the output ends of at least two drive components 120, and the second limiting seat 142 is sleeved on the connection ends of at least two drive components 120. The output ends of at least two drive components 120 are fixed to at least two fixing parts 1131 via the first limiting seat 141, and the connection ends of at least two drive components 120 abut against the power control part 131 via the second limiting seat 142. In other words, the first limiting seat 141 and the second limiting seat 142 of the limiting component 140 limit and fix both ends of at least two drive components 120, thereby forming a unified structure for all drive components 120. This effectively constrains the relative positions of the drive components 120, ensuring that the drive components 120 maintain parallel axes during operation, and effectively preventing mechanical interference caused by axis misalignment due to vibration.

[0038] The first limiting seat 141 may be provided with a limiting groove 1411, and at least two fixing parts 1131 are provided with limiting blocks 1132 corresponding to the limiting groove 1411. The limiting blocks 1132 are engaged in the limiting groove 1411 to form a limiting engagement relationship. In this way, by utilizing the engagement between the limiting groove and the limiting block, the radial offset of the drive assembly 120 during operation can be further reduced.

[0039] The limiting groove 1411 and the limiting block 1132 can be in multiple sets. The multiple sets of limiting groove 1411 and limiting block 1132 can be arranged around at least two drive components 120. This further improves the offset effect and reduces the assembly difficulty between the drive component 120 and the fixed seat 113.

[0040] The first limiting seat 141 and / or the second limiting seat 142 can be made of soft rubber material to achieve shock absorption and further buffer the vibration generated when the drive component 120 is working.

[0041] In some embodiments, the limiting component 140 may further include at least one damping column 143 disposed on the second limiting seat 142. The second limiting seat 142 abuts against the outer wall of the power control unit 131 via the damping column 143. The damping column 143 may extend in a direction perpendicular to the second limiting seat 142. It is understood that the damping column 143 is a columnar buffer component with elastic deformation capability; for example, the damping column 143 may be made of rubber or silicone. The second limiting seat 142 abuts against the outer wall of the power control unit 131 via the damping column 143, effectively absorbing the axial vibration energy generated during the operation of the drive component 120. In other words, the damping column 143 can be used to elastically block the transmission path of vibration generated during the operation of the drive component 120 to the power control unit 131, thereby effectively avoiding resonance caused by direct contact between the second limiting seat 142 and the power control unit 131.

[0042] The use of soft rubber material in the first limiting seat 141, in conjunction with the shock-absorbing column 143, creates a shared vibration damping effect at both ends of the drive components 120 assembled into the housing. By using the soft rubber material in the first limiting seat 141 and the shock-absorbing column 143 at both ends of the drive component 120, it can be suspended within the housing 110, effectively reducing the transmission of vibrations generated by the drive component 120 during operation to the housing 110, thereby reducing noise transmitted to the outside of the housing 110. Furthermore, the use of soft rubber material at both ends for clamping prevents a rigid connection between the drive component 120 and the inner wall of the housing 110, thus improving the structural stability and service life of the product.

[0043] The axial length of the damping column 143 is greater than that of the second limiting seat 142. That is, the length of each damping column 143 protrudes beyond the end face of the second limiting seat 142, which ensures that the damping column 143 preferentially abuts against the power control unit 131 during assembly, and ensures that after assembly, the damping column 143 can be compressed to increase its contact surface with the power control unit 131, thereby further improving the damping effect provided by the damping column 143.

[0044] In some embodiments, the outer wall of the power control unit 131 is provided with at least one receiving groove 1311 corresponding to at least one damping column 143, and each damping column 143 is received within a receiving groove 1311. It can be understood that by constraining the displacement direction of the damping column 143 through the receiving groove 1311 on the outer wall of the power control unit 131, the damping column 143 can maintain its vertical elastic deformation during vibration. The depth of the receiving groove 1311 and the height of the damping column 143 form an interference fit, preventing the damping column 143 from moving freely after being pressed into the receiving groove 1311.

[0045] In some embodiments, the end cap control unit 132 has two symmetrically arranged control areas on two opposite sides. It is understood that the two control areas have the same control functions.

[0046] Each control area 1321 may include at least one of a control button and a power interface. The control button may be at least one physical button for controlling functions such as start / stop and mode switching. The power interface may be a connection port for connecting an external power supply line. For example, the power interface may be a Type-C or DC socket. By symmetrically arranging two identical control areas on both sides of the end cover control section 132, when the device is installed on a curtain track, regardless of whether the end cover control section 132 faces left or right, the user can operate or connect the device from the exposed side through the corresponding control area. That is, the symmetrical structure of the two control areas allows the drive device of this application to adapt to different installation orientations.

[0047] Figure 5 This is a schematic diagram of the end cover control section in the drive device shown in the embodiment of this application.

[0048] Please see also Figure 5 In some embodiments, the end cap control unit 132 may include a control body 1322 and a protective panel 1323. The control body 1322 can serve as a carrier for setting the control functions of the end cap control unit 132. For example, a control board for controlling the operation of the drive device may be integrated within the control body 1322. The protective panel 1323 is detachably fitted onto the front of the control body 1322 by engaging with slots on the control body 1322 via snap-fit ​​fasteners around its periphery, thereby enabling quick assembly between the control body 1322 and the protective panel 1323.

[0049] It is understandable that the protective panel 1323 can also be used as a decorative part on the surface of the end cap control part 132. By replacing the protective panel 1323 with different colors or surface treatments, different appearance design requirements can be met.

[0050] In some embodiments, the end cap control unit 132 may further include an antenna (not shown) for receiving external signals. The antenna is integrated into the control body 1322 and faces the protective panel 1323. This effectively ensures the orientation of the antenna's received signal, thereby improving the stability of signal reception. It is understood that the antenna can be used to receive wireless control signals such as Wi-Fi, Bluetooth, and Zigbee. By transmitting the signals received by the antenna to the control board integrated within the control body 1322, remote control of the drive device can be achieved. Furthermore, since the end cap control unit 132 is still exposed outside the curtain track when the drive device is assembled to the curtain track, placing the antenna in the end cap control unit 132 effectively ensures the signal reception effect of the drive device.

[0051] Placing the antenna between the control body 1322 and the protection panel 1323 can effectively protect the antenna.

[0052] The protective panel 1323 can also be made of non-metallic materials such as plastic, thereby reducing the impact on signal transmission and providing an unobstructed signal transmission path for the antenna, thus effectively ensuring the stability of the communication process.

[0053] In this embodiment, the drive device of this application integrates the power supply and drive assembly within the same housing by housing the power control unit through an installation opening on the same side of the drive assembly. The power control unit is electrically connected to the drive assembly via a power control board integrated within the power control unit. This integrated and compact design effectively eliminates the problem of long wires required for separate power supply units, avoiding folding and binding issues caused by redundant wires in small-size applications, improving the internal neatness of the product, and reducing the risk of wires tangling or scratching with rotating parts within the track. This eliminates abnormal noises and safety hazards during product use, improving the user experience. Furthermore, in practical applications, integrating the power supply and drive assembly and placing them simultaneously at the same end of the electric curtain track effectively reduces the overall length of the winding control mechanism, facilitating a balanced layout of the traction rope on the electric curtain. This effectively prevents sagging caused by the lack of rope traction within a long track, improving the stability of the electric curtain during use.

[0054] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a winding mechanism and corresponding embodiments.

[0055] The winding mechanism of this application includes the driving device shown in the foregoing embodiments.

[0056] The winding mechanism of this application can be applied to electric curtains. By using a drive device to drive the winding module in the electric curtain, the lifting rope in the winding module can be raised and lowered, thereby controlling the curtain fabric of the electric curtain.

[0057] In this embodiment, the drive device achieves an integrated and compact design of the power supply and drive components, which can effectively eliminate the problem of long wires required due to separate power supply. This can effectively isolate moving parts such as drive shafts and winding modules from the wires, reducing the risk of wire tangling. At the same time, by eliminating the long wire design in traditional solutions, the internal space of the curtain track can be made more abundant.
