Description

Technical Field

[0001] This utility model relates to a power device, and more particularly to an electric curtain drive device. Background Technology

[0002] As people's demands for home life continue to increase, more and more families are starting to install electric curtains, which can be opened or closed by controlling the drive mechanism of the electric curtains.

[0003] Existing motorized curtain drive mechanisms typically include a drive box and a transmission box. The drive box contains a motor, and the transmission box contains gears for transmission. A clutch device is installed between the motor and the transmission gears to enable manual operation of the motorized curtain. For easy control of the motor and power supply, a power circuit board and a control circuit board are usually provided. These two circuit boards are mounted side-by-side or centrally mounted at the bottom, connected by wire soldering or by adding plug-in terminals to the wires. All components are assembled inside a large housing. For example, Chinese Patent Application No. 202323034531.6 discloses a curtain motor structure suitable for track-type curtains, including a motor body module and a track docking module. The motor body module includes a housing, a step-down circuit board, a control circuit board, a drive motor, a motor mounting plate, a transmission mechanism, and a clutch-type output shaft. Two slots are arranged side-by-side inside the housing, and the step-down circuit board and the control circuit board are respectively inserted into the two slots.

[0004] This existing technology has the following problems:

[0005] 1. All components are installed inside the casing, which is usually quite deep. It requires careful eye alignment of various slots and holes. Due to the small size of the product, the internal space of the casing is small and relatively enclosed, making manual assembly very inconvenient.

[0006] 2. If circuit boards are connected to each other or to motors via wires, the wiring method and space must be considered during assembly. It is inconvenient to manually insert terminals (the terminals are small). Connecting motors and control circuit boards via wire soldering involves multiple steps and is also inconvenient. There are also problems such as the wires being easily broken when pulled.

[0007] Therefore, further improvements are needed. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide an electric curtain drive device that improves assembly convenience, addressing the shortcomings of the existing technology.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: an electric curtain driving device, comprising a drive box, wherein the drive box includes a motor, a reduction gearbox, a power circuit board, a control circuit board, and a housing; characterized in that:

[0010] The drive box also includes a bracket, on which the motor, gearbox, power circuit board and control circuit board are respectively mounted. The bracket is detachably installed inside the housing.

[0011] By setting up a bracket, the components of the drive box can be assembled completely exposed on the bracket without a shell. The shell is then put on after assembly. Without the limitations of a small space and obstructed view, assembly is very easy.

[0012] Furthermore, to optimize the spatial distribution within the housing, making the internal structure of the housing more compact and the external dimensions smaller, the motor power supply circuit board is longitudinally extended and mounted on the bracket, and the control circuit board is laterally extended and mounted on the bottom of the bracket.

[0013] To facilitate the assembly and disassembly of the power circuit board and the bracket, a notch is formed on the power circuit board, and a corresponding snap-fit ​​is formed on the bracket to mate with the notch.

[0014] Furthermore, the power supply circuit board is located above the control circuit board. The power supply circuit board includes a first terminal, and the control circuit board includes a second terminal. The first and second terminals are plugged into each other to achieve electrical connection. The power supply circuit board and the control circuit board are connected by direct-plugging terminals, eliminating the need for wires, avoiding the risk of wire breakage, and eliminating the need for manual assembly with small plug-in terminals, making assembly convenient and quick.

[0015] Preferably, the bracket includes an integrally formed first part and a second part, the second part being a hollow cylinder, the first part being formed around the periphery of the second part, the motor and the gearbox being placed inside the second part, and the power circuit board being mounted on the first part.

[0016] Furthermore, the motor has a conductive insert at its bottom, and the control circuit board includes a spring-loaded connecting piece. The conductive insert is directly inserted into the spring-loaded connecting piece to achieve electrical connection between the motor and the control circuit board. The motor and control circuit board are also connected via a direct insertion method, eliminating the soldering step, saving processes and space, and avoiding the risk of wire breakage.

[0017] Furthermore, to facilitate the insertion of the bracket into the housing and the sealing of the housing, the bottom of the housing is open, and the bracket is installed into the housing from bottom to top. The drive box also includes a base fixed to the bracket, which is located at the bottom of the housing and seals the bottom of the housing.

[0018] Preferably, the power cord of the power circuit board extends downward from the base, and the drive box further includes a power cord fixing component for fixing the power cord.

[0019] Compared with the prior art, the advantages of this utility model are as follows: By setting up a bracket, the components of the drive box can be assembled in full exposure on the bracket without a shell. The shell is then put on after assembly, eliminating the limitations of a small space and obstructing the view, making assembly very easy; the power circuit board and the control circuit board are connected by direct-plug terminals, eliminating the need for wires and avoiding the risk of wire breakage. It also eliminates the need for manual assembly with small plug terminals, making assembly convenient and quick; the motor and the control circuit board are also connected by direct-plug terminals, eliminating the soldering step, saving processes and space, and avoiding the risk of wire breakage.

[0026] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] See Figures 1-6 An electric curtain drive device includes a drive box 100, a transmission box 200, a latch 300 for locking the drive box and the transmission box 200, and a battery module 400. The drive box 100 includes a motor 1, and the transmission box 200 may include gears or other components that are drively connected to the motor 1. The drive box 100 and the transmission box 200 are locked together by the latch 300. The mechanical and transmission connections between the drive box 100 and the transmission box 200 can all utilize existing technologies, which will not be elaborated further here.

[0029] The drive housing 100 also includes a clutch mechanism 2, a reduction gearbox 3, a gear 4, a rotating wheel 5, a power circuit board 6, a control circuit board 7, a base 8, a bracket 9, a power cord fixing component 10, and a housing 11. The bracket 9 includes an integrally formed first part 91 and a second part 92, wherein the first part 91 is formed around the periphery of the second part 92, and the second part 92 is a hollow cylinder. The aforementioned motor 1 and reduction gearbox 3 are housed within the second part 92, and the reduction gearbox 3 is connected to the output shaft of the motor 1. The clutch mechanism 2 is connected to the output end of the reduction gearbox 3 and is located above the reduction gearbox 3.

[0030] The power circuit board 6 is mounted longitudinally on the first part 91 of the bracket 9. Here, "longitudinal extension" means that when the drive device is installed, the output shaft of the motor 1 extends longitudinally (i.e., extends vertically, usually in a vertical direction), and the power circuit board 6 is arranged in the same direction as the output shaft of the motor 1. The power circuit board 6 is usually rectangular, and it may have notches 61 formed at its four corners. The bracket 9 has corresponding latches 93, which can engage with the notches 61 to fix the power circuit board 6 and the bracket 9.

[0031] A bracket 9 is housed within a housing 11, with an opening at the bottom. A base 8 is positioned at the bottom of the housing 11, closing the bottom of the housing 11. A control circuit board 7 extends laterally and is mounted on the base 8, its extension direction being perpendicular or nearly perpendicular to the extension direction of the power circuit board 6. The control circuit board 7 is located below the bracket 9 and can be fixed to the bottom of the bracket 9 with screws, with the fixing position being in the middle of the control circuit board 7. The control circuit board 7 can also be fixed to the base 8 with screws, with the fixing positions being at the four corners of the control circuit board 7. When the base 8 is fixed to the housing 11 (using screws), the control circuit board 7 is also fixed together. The base 8 and the bracket 9 can be snapped together for secure fastening.

[0032] The power circuit board 6 is located on top of the control circuit board 7, and the two can be connected via a direct-plug terminal. The power circuit board 6 includes a first terminal 62, and the control circuit board 7 includes a second terminal 71. Electrical connection is achieved by plugging in the two terminals. The power input of the motor 1 uses a conductive insert 101, which is located at the bottom of the motor 1 and extends out of the bracket 9. The control circuit board 7 includes a spring-loaded connecting piece 72, which has a coiled structure. The conductive insert 101 can be directly inserted into the spring-loaded connecting piece 72 to achieve electrical connection. In this embodiment, the control circuit board 7 is powered by a battery module 400 connected below the drive box 100. Alternatively, the power circuit board 6 can be connected to an external power source. In this case, the power cord (not shown) of the power circuit board 6 extends downward from the base 8 and can be fixed with a power cord fixing piece 10 to prevent the power cord from being pulled out.

[0033] Gear 4 is connected to clutch mechanism 2 and can drive wheel 5 to rotate for stroke detection. The stroke detection structure is the same as existing technology, such as the combination of commonly used magnets and Hall elements. Gear 4 and wheel 5 are rotatably mounted on the first part 91 of bracket 9, located on the side of power circuit board 6 near bracket 9.

[0034] The aforementioned motor 1, clutch mechanism 2, gearbox 3, gear 4, wheel 5, power circuit board 6, control circuit board 7, base 8, and power cord fixing piece 10 can be first installed onto bracket 9, then bracket 9 can be installed into housing 11, and finally base 8 and housing 11 can be fixed together. Thus, all components can be assembled completely exposed without housing 11, and only after all components are assembled can housing 11 be fitted over them. Without the constraints of a confined space and obstructed view, assembly is extremely easy.
