Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and in particular to a mini double-head output motor suitable for wide-width Venetian blinds. Background Technology

[0002] As the application of Venetian blinds expands, the use of mini Venetian blinds on single and double-glazed windows is becoming increasingly common. Various compatible aluminum profile frame structures are constantly being innovated. For example, the installation of motors and batteries, and the integration of glass and curtain fabric, all require the design of compatible aluminum profile frame shapes. These specially sized aluminum profiles have narrow applications and poor versatility, yet distributors are forced to purchase and stock large quantities of these special-sized profiles to accommodate various Venetian blinds, resulting in significant inventory pressure for them. Utility Model Content

[0003] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a mini double-head output motor suitable for wide-width small venetian blinds. It is easy to install, has a compact structure, and can be used with aluminum profiles of common sizes in the market, thus solving the problem of inventory pressure for distributors who need to keep a large number of special-sized aluminum profiles.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a mini dual-head output motor suitable for wide-width small Venetian blinds, including a drive mechanism, a controller, and a battery. The drive mechanism, controller, and battery are connected sequentially via a ribbon cable, and the battery is connected to one end of the ribbon cable.

[0005] The drive mechanism includes a fixed housing, a motor core, a reducer, a main board, and a hexagonal bar. The main board is connected to the other end of the ribbon cable and is electrically connected to the motor core. There are two reducers, which are respectively driven and connected to the two ends of the motor core. The hexagonal bar is driven and connected to the end of the reducer away from the motor core. The motor core, reducer, and hexagonal bar are coaxially arranged. The main board, motor core, and reducer are housed inside the fixed housing, while the hexagonal bar protrudes outside the fixed housing.

[0006] Furthermore, the controller includes a travel plate housing and a travel plate, the travel plate being disposed within the travel plate housing, and the travel plate being connected to the motherboard and the battery respectively via ribbon cables.

[0007] Furthermore, the travel plate is arranged longitudinally in sequence with an up key, a stop key, and a down key, and the travel plate shell has exposed up keycaps, stop keycaps, and down keycaps corresponding one-to-one with the up key, stop key, and down key.

[0008] Furthermore, the travel plate is provided with a type-C port, and a silicone protective cover is installed on the travel plate shell corresponding to the type-C port.

[0009] Furthermore, the fixed shell includes a detachably connected upper shell and a bottom shell. The inner sides of the upper shell and the bottom shell are provided with a plurality of limiting blocks for limiting the motor core and the reducer, and the inner sides of the upper shell and the bottom shell are provided with a plurality of slots for the motherboard to be inserted.

[0010] Furthermore, the upper shell and the bottom shell are respectively fixedly connected to the reducer by self-tapping screws.

[0011] Furthermore, the limiting block is provided with a first screw mounting hole, the reducer is provided with a second screw mounting hole, and the self-tapping screw is screwed into the first screw mounting hole and the second screw mounting hole.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: By setting up a three-part structure consisting of a drive mechanism, a controller, and a battery, the structure of each part of this utility model is smaller and easier to install; furthermore, by using a ribbon cable to connect the drive mechanism, controller, and battery, the connection structure is simplified, thus reducing the size; and by connecting the battery to the end of the ribbon cable, batteries of different capacities can be freely combined according to the size of the aluminum profile, thereby meeting the need for long-lasting operation; the length of the ribbon cable can also be adjusted according to actual usage requirements. By outputting power to the hexagonal bars at both ends of the motor core, the motor core can be installed in the middle of the window profile, preventing the hexagonal bars driven by the motor core from breaking due to excessive profile length. This also makes the force on the hexagonal bars driven by the motor core more balanced, thereby improving the motor's lifespan.

[0013] Compared to customizing and purchasing various special-sized aluminum profiles, replacing different sized ribbon cables and batteries is obviously more convenient; moreover, the ribbon cables and batteries are highly versatile and occupy little space, effectively alleviating the inventory pressure on distributors; furthermore, the capacity of ordinary embedded venetian blind batteries has an upper limit and cannot be freely combined, while this utility model, by connecting the battery to the end of the ribbon cable, facilitates the combination of batteries of different capacities, thereby meeting the demand for long-lasting battery life. Placing the motor core, reducer, and mainboard in a fixed housing protects these three important structures and also makes installation easier. Attached Figure Description

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] 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", "circumferential", etc., indicating the orientation or positional relationship, 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, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] like Figure 1-4 As shown, a mini dual-head output motor suitable for wide-width Venetian blinds includes a drive mechanism, a controller, and a battery 11. The drive mechanism, controller, and battery 11 are connected sequentially via a ribbon cable 12, with the battery 11 connected to one end of the ribbon cable 12.

[0025] The drive mechanism includes a fixed housing 1, a motor core 2, a reducer 3, a main board 4, and a hexagonal bar 5. The main board 4 is connected to the other end of the ribbon cable 12 and is electrically connected to the motor core 2. There are two reducers 3, which are respectively driven and connected to the two ends of the motor core 2. The hexagonal bar 5 is driven and connected to the end of the reducer 3 away from the motor core 2. The motor core 2, reducer 3, and hexagonal bar 5 are coaxially arranged. The main board 4, motor core 2, and reducer 3 are arranged inside the fixed housing 1, and the hexagonal bar 5 is exposed outside the fixed housing 1.

[0026] This invention features a three-part structure comprising a drive mechanism, a controller, and a battery 11, resulting in a compact and easy-to-install design. Furthermore, a ribbon cable 12 connects the drive mechanism, controller, and battery 11, simplifying the connection structure and reducing overall size. Connecting the battery 11 to the end of the ribbon cable 12 allows for flexible combinations of batteries of different capacities to suit various aluminum profile dimensions, thus meeting long-lasting battery life requirements. The length of the ribbon cable 12 can also be adjusted according to actual usage needs. By directing power from the motor core 2 to the hexagonal rods at both ends, the motor core 2 can be installed in the middle of the window profile, preventing breakage of the hexagonal rods 5 driven by the motor core 2 due to excessive profile length. This ensures more balanced force distribution on the hexagonal rods 5 driven by the motor core 2, thereby extending the motor's lifespan.

[0027] Preferably, the controller includes a travel plate housing 6 and a travel plate 7, with the travel plate 7 disposed within the travel plate housing 6. The travel plate 7 is connected to the main board 4 and the battery 11 respectively via a ribbon cable 12. Using a single travel plate 7 results in a smaller size and better fits narrow-bezel profiles.

[0028] Preferably, the travel plate 7 is longitudinally arranged with an up key 7.1, a stop key 7.2, and a down key 7.3, and the travel plate housing 6 has exposed up keycaps 13, 14, and 15 corresponding to the up key 7.1, stop key 7.2, and down key 7.3, respectively. This design conforms to the intuitive operation of opening and closing the Venetian blinds and is convenient for users.

[0029] Preferably, the travel plate 7 is provided with a type-C port 9, and the travel plate shell 6 is equipped with a silicone protective cover 10 corresponding to the type-C port 9, which serves to protect the type-C port 9 from dust.

[0030] Preferably, the fixed housing 1 includes a detachably connected upper housing 1.1 and a bottom housing 1.2. The inner sides of the upper housing 1.1 and the bottom housing 1.2 are provided with a plurality of limiting blocks 1.3 for limiting the motor mechanism 2 and the reducer 3, and the inner sides of the upper housing 1.1 and the bottom housing 1.2 are provided with a plurality of latches 1.4 for the main board 4 to be inserted. The limiting blocks 1.3 are used to limit the motor mechanism 2 and the reducer 3, and the latches 1.4 are used to limit the main board 4.

[0031] Preferably, the upper shell 1.1 and the bottom shell 1.2 are fixedly connected to the reducer 3 by self-tapping screws 1.5. By fixing the upper shell 1.1 and the bottom shell 1.2 with self-tapping screws 1.5, the limiting block 1.3 and the bayonet 1.4 can fix the motor core 2, the reducer 3 and the main board 4, thereby reducing the encroachment of the snap-fit ​​structure on the motor space.

[0032] Preferably, the limiting block 1.3 is provided with a first screw mounting hole 1.3.1, the reducer 3 is provided with a second screw mounting hole 3.1, and the self-tapping screw 1.5 is screwed into the first screw mounting hole 1.3.1 and the second screw mounting hole 3.1, thereby fixing the limiting block 1.3 and the reducer 3.

[0033] The method of using this utility model is as follows: The drive mechanism, controller, and battery 11 are respectively installed in the aluminum profiles of the venetian blind frame. Before installation, select a suitable length of the ribbon cable 12 and a battery of appropriate size according to the dimensions of the aluminum profiles. After installation, press the up button 13, stop button 14, and down button 15 located on the fixed housing 1 to control the operation of the motor mechanism 2. Alternatively, a longer ribbon cable 12 and a smaller battery 11 can be used to make this utility model more versatile, allowing it to be directly placed in aluminum profile frames of different sizes.

[0034] The advantages of this utility model are as follows: Compared to customizing and purchasing aluminum profiles of various special sizes, it is obviously more convenient to replace the ribbon cable 12 and battery 11 of different sizes; moreover, the ribbon cable 12 and battery 11 are highly versatile and occupy little space, which can effectively alleviate the inventory pressure of distributors; furthermore, the capacity of ordinary embedded venetian blind batteries has an upper limit and cannot be combined arbitrarily, while this utility model, by connecting the battery 11 to the end of the ribbon cable 12, facilitates the combination of batteries 11 of different capacities, thereby meeting the requirements for long-lasting battery life. Placing the motor core 2, reducer 3, and main board 4 in the fixed housing 1 can protect these three important structures and also makes installation more convenient.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
