[0001] This utility model relates to the field of motor technology, and in particular to a dual-motor mechanism. Background Technology

[0002] The electric curtain is equipped with a dual-motor mechanism, a gauze assembly, and a curtain assembly. The dual-motor mechanism uses two motors, one of which drives the gauze assembly to close or open, and the other motor drives the curtain assembly to close or open.

[0003] Accordingly, existing dual-motor mechanisms are divided into main and auxiliary motors, requiring differentiation between them during production. The main motor includes a motor, control board, power board, and an adapter board A, while the auxiliary motor includes a motor and an adapter board B. The main and auxiliary motors must be clearly distinguishable in structure and appearance. They must be differentiated during shipping and on-site installation to ensure accurate operation.

[0004] However, the aforementioned dual-motor mechanism requires differentiation between the main unit and the auxiliary unit not only in production, distribution, and use, but also in the subsequent use and maintenance of the electric curtains. In particular, when the main unit and the auxiliary unit are misaligned, both units need to be disassembled, leading to complex technical issues related to disassembly, assembly, and maintenance. Therefore, improvements are needed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a dual-motor mechanism to solve the technical problem of high costs associated with the separate use of the main and auxiliary motors.

[0006] According to a first aspect of the present invention, a dual-motor mechanism is provided, comprising:

[0007] Two motor assemblies, wherein the side of each motor assembly protrudes and extends to form an extension section, and an installation notch is formed between the motor assembly and the extension section;

[0013] In one embodiment, one of the control box assembly and the motor assembly is provided with a slide groove, and the other is provided with a sliding arm, with a portion of the sliding arm slidably confined within the slide groove.

[0014] In one embodiment, the dual-motor mechanism further includes a hollow box assembly mounted on another motor assembly.

[0015] In one embodiment, the shape of the empty box assembly is the same as that of the control box assembly.

[0016] In one embodiment, the empty box assembly includes a removable plug structure, which, when removed, forms a corresponding hole space on the surface of the empty box assembly.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] like Figures 1 to 4 As shown, this utility model provides a dual-motor mechanism, which includes a control box assembly 20, a connecting wire 30, and two motor assemblies 10. An extension segment 12 protrudes from the side of each motor assembly 10, and an installation notch 11 is formed between the side of the motor assembly 10 and the extension segment 12.

[0030] The motor assembly 10 has an overall L-shaped structure. The control box assembly 20 can be detachably installed in the mounting notch 11 of any motor assembly 10, and the control box assembly 20 and the mounting notch 11 are complementary. The motor assemblies 10 adopt the same structure and can share the same control box assembly 20. There is no need to distinguish between the main and auxiliary machines, which can realize material unification, greatly improve the efficiency of material use and turnover, and reduce costs.

[0031] The connecting cable 30 electrically connects the control box assembly 20 to each of the two motor assemblies 10. Optionally, the control box assembly 20 is provided with two external interfaces 22, each external interface 22 connecting to a connecting cable 30, and each connecting cable 30 connecting to one motor assembly 10. This allows the control box assembly 20 to control both motor assemblies 10 via the connecting cables 30. After the dual-motor mechanism is installed on the track of the motorized curtain, if the two motor assemblies 10 need to be interchanged, only the installation position of the control box assembly 20 needs to be removed, without disassembling the motor assemblies 10, greatly improving replacement and maintenance efficiency and reducing costs.

[0032] The control box assembly 20 can be integrated with the motor assembly 10, and the control box assembly 20 and the motor assembly 10 are detachably connected, each being an independent unit. For example, the control box assembly 20 is locked to the motor assembly 10 by fasteners. Alternatively, the control box assembly 20 and the motor assembly 10 are connected by a quick-release structure.

[0033] In one embodiment, the control box assembly 20 and the motor assembly 10 are snap-fit ​​connected to each other for quick assembly and disassembly. For example, either the control box assembly 20 or the motor assembly 10 has at least two snap-fit ​​ribs, and the other has a snap-fit ​​groove corresponding to the snap-fit ​​ribs. When the control box assembly 20 is assembled to the motor assembly 10 along the mounting notch 11, the snap-fit ​​ribs are snapped into the snap-fit ​​grooves.

[0034] In this embodiment, the snap ribs and snap grooves can be distributed on the first side or the second side of the mounting notch 11, and the first side and the second side are the intersecting surfaces of the mounting notch 11 to form a matching snap connection.

[0035] Furthermore, one of the control box assembly 20 and the motor assembly 10 is provided with an elastically deformable arc-shaped rib 21, and the other is provided with a snap-fit ​​groove 13 that adapts to the arc-shaped rib 21. The control box assembly 20 and the motor assembly 10 are slidably connected, and the arc-shaped rib 21 and the snap-fit ​​groove 13 are snap-locked together.

[0036] The arc-shaped protrusion 21 and the snap-fit ​​groove 13 are respectively distributed on the sliding mating parts of the control box assembly 20 and the motor assembly 10. After the control box assembly 20 slides into place, it is elastically snapped and positioned, thereby positioning the control box assembly 20 to the motor assembly 10.

[0037] Optionally, the control box assembly 20 is provided with at least one arc-shaped protrusion 21, and the motor assembly 10 is provided with an arc-shaped groove. The control box assembly 20 is slidably connected to the motor assembly 10. The top end of the arc-shaped protrusion 21 extends beyond the sliding mating surface of the control box assembly 20 and the motor assembly 10, and the arc-shaped groove is recessed relative to the sliding mating surface. The arc-shaped protrusion 21 is compressed during the sliding process of the control box assembly 20, and elastically resets and snaps into the arc-shaped groove after it is in place, thereby forming a snap-fit ​​positioning.

[0038] like Figures 2 to 5 As shown, during the sliding engagement of the control box assembly 20 and the motor assembly 10, the control box assembly 20 is limited to the motor assembly 10, so that the control box assembly 20 has a degree of freedom in the sliding direction, while the degrees of freedom in other directions are restricted.

[0039] In one embodiment, one of the control box assembly 20 and the motor assembly 10 is provided with a slide groove 151, and the other is provided with a sliding arm 261, with a portion of the sliding arm 261 slidably confined within the slide groove 151.

[0040] The slide groove 151 and the sliding arm 261 are complementary guide structures. Optionally, the sliding arm 261 has a T-shaped structure, and the slide groove 151 is configured with a T-shaped structure, with the slide groove 151 slidably connected to the sliding arm 261. Optionally, the sliding arm 261 has a dovetail-shaped structure, and the slide groove 151 is configured with a dovetail groove structure. Preferably, the slide groove 151 has a double-groove structure.

[0041] In one specific embodiment, the control box assembly 20 includes two upright sliding arms 261, with the wall surface of the sliding arms 261 protruding to form sliding ribs. The opposite sides of the motor assembly 10 are recessed to form sliding grooves 151. The two sliding arms 261 are engaged with the two sides of the motor assembly 10, and the sliding ribs are inserted into the sliding grooves 151 to form directional sliding. The control box assembly 20 only has the degree of freedom in the sliding direction.

[0042] The arc-shaped rib 21 is disposed in the space between the two sliding arms 261. Preferably, two arc-shaped ribs 21 are disposed to improve the stability of the buckle.

[0043] In one embodiment, the control box assembly 20 includes a housing 26, a control board 25 located inside the housing 26, and a power board 24. The power board 24 is connected to a power cord 23, and the control board 25 is electrically connected to the power board 24. The control board 25 is provided with at least two external interfaces 22, and a connecting cable 30 is plugged into the external interfaces 22.

[0044] The outer casing 26 is a hollow shell structure, with arc-shaped ribs 21 and sliding arms 261 distributed on the outer surface of the outer casing 26. The control board 25 and power board 24 are located inside the outer casing 26. The external interface 22 and the connecting cable 30 adopt a plug-in mating structure to realize the transmission of signals and electrical energy.

[0045] At least two external interfaces 22 are provided, which can realize the control of two motor assemblies 10.

[0046] Optionally, the control box assembly 20 is equipped with a button area 27, and the control board 25 is provided with control buttons adapted to the button area 27.

[0047] like Figures 3 to 5As shown, based on the above embodiment, the dual-motor mechanism further includes a hollow empty box assembly 40, which is installed on the other motor assembly 10. Since the control box assembly 20 is installed on one of the motor assemblies 10, the mounting notch 11 of the other motor assembly 10 is left empty. The empty box assembly 40 is installed into the empty mounting notch 11, thereby complementing the mounting notch 11.

[0048] Preferably, the empty box assembly 40 has the same shape as the control box assembly 20, so the empty box assembly 40 and the control box assembly 20 can be installed interchangeably. The empty box assembly 40 and the control box assembly 20 can be interchanged and assembled without removing the motor assembly 10.

[0049] Preferably, the internal space structure of the empty box assembly 40 is the same as that of the internal space structure of the outer shell 26, allowing the control board 25 and the power board 24 to be assembled inside the empty box assembly 40 to form a new control box assembly 20. That is, the empty box assembly 40 is assembled into the motor assembly 10 as a spare shell, facilitating subsequent maintenance.

[0050] Further preferably, the empty box assembly 40 includes a removable plug structure 41, which, when removed, forms a corresponding hole space on the surface of the empty box assembly 40. The empty box assembly 40 serves as an alternative housing, wherein the plug structure 41 seals the hole space of the empty box assembly 40 to prevent foreign objects from falling into the empty box assembly 40 and maintain the cleanliness of the internal environment.

[0051] like Figure 2 and Figure 6 As shown, in one embodiment, the motor assembly 10 includes a motor housing 15 and a motor assembly 14 mounted within the motor housing 15. The output end of the motor assembly 14 extends out of the motor housing 15, and an extension 12 partially protrudes from one side of the motor housing 15. The motor assembly 14 is distributed within the motor housing 15, and the output shaft of the motor assembly 14 is located at the end of the motor housing 15. The control box assembly 20 is connected to the motor assembly 14 via a connecting cable 30 to control the operation of the motor assembly 14.

[0052] Furthermore, the motor assembly 14 includes a power motor 142, a reducer 141, and an adapter plate 143. The adapter plate 143 is provided with an adapter interface 16, and the connecting cable 30 is plugged into the adapter interface 16. The adapter interface 16 is located at the end of the motor housing 15, and the adapter plate 143 is connected to the power motor 142, thereby facilitating the spatial layout of the power motor 142 and the reducer 141 inside the motor housing 15.

[0053] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
