Description

Technical Field

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

[0002] A tubular motor consists of a stroke section, a motor section, and a reduction gear section, all of which operate within a circular tube, hence its name. In existing technologies, the stroke section, motor section, and reduction gear section of a tubular motor are often directly installed inside the tubular motor, with each component working together to form a whole. Although this achieves a higher degree of integration, it makes repair difficult in the event of damage during long-term use.

It solves the problems of excessive length and inconvenient installation of existing tubular motors used in electric curtains. The technical solution mainly includes a motor for driving the roller, comprising a housing, a motor body, and a circuit board. The housing includes a first cavity for mounting the motor body and a second cavity for wiring. The second cavity is located to the side of the first cavity, and the circuit board is installed within the second cavity. This invention primarily aims to effectively shorten the length of tubular motors used in electric curtains while making wiring routing more efficient and easier to install.

[0004] However, this technical solution has the following problems: First, it occupies a large space, requiring an additional second cavity to install wires and circuit boards; second, it is complicated to repair, as the circuit board is installed in the second cavity, and whether the problem is with the motor itself or the circuit board, the entire motor needs to be disassembled for repair.

[0040] Example 1

[0041] like Figure 1-6As shown, this embodiment provides a modular dual-output tubular motor, including a housing 1 and a drive unit 2 and a transmission unit 3 installed inside the housing 1. The drive unit 2 includes an output shaft 21, which is connected to the transmission unit 3. The drive unit 2 and the transmission unit 3 are modularly arranged and are circumferentially anti-misaligned, with a circumferential fitting structure at the connection point. The housing 20 of the drive unit 2 abuts against the inner wall of the housing 1. The transmission unit 3 and the housing 1 are spaced apart by an annular space 11 for wiring harness routing, with a fixing sleeve 31 installed at its outer end. The fixing sleeve 31 abuts against the inner wall of the housing 1 and has a through hole 311 communicating with the annular space 11.

[0042] By modularizing the drive unit 2 and transmission unit 3, the motor structure becomes clearer, making it easier to repair or replace individually, reducing maintenance costs, and solving the problem of complex maintenance of tubular motors.

[0043] The drive unit 2 is externally connected to a control unit 4. The wiring harness passes through the annular space 11 and the through hole 311 to electrically connect the drive unit 2 and the control unit 4. It should be noted that the control unit 4 is independently set outside the tubular motor, enabling it to realize more control functions, such as adding an external LED power supply, adding a remote control module, etc., to realize multiple control methods and control other external devices. Furthermore, because the control unit 4 is independently set, it is convenient to repair or replace it separately.

[0044] By providing an annular space 11 for wire harness routing between the transmission unit 3 and the outer casing 1, this invention eliminates the need for additional openings or wiring cavities to accommodate the wire harness, reducing the radial space occupied by the invention and enabling its use in narrower environments, thus expanding its applicability.

[0045] like Figure 2 , 5 As shown, the drive unit 2 further includes: a rotor 22, sleeved on the middle of the output shaft 21 and rotating synchronously with the output shaft 21; a stator 23, sleeved on the outside of the rotor 22 with a gap between it and the rotor 22; a sleeve 24, installed on both sides of the stator 23; and a bearing seat 25, installed on the outside of the sleeves 24 on both sides, with a bearing 26 movably connected to the output shaft 21 installed in its middle; the stator 23, sleeve 24 and bearing seat 25 are circumferentially limited, and the outer arc surfaces of the three are provided with a plurality of mutually cooperating limiting structures 27. In this embodiment, the limiting structures 27 on the outside of the stator 23 and bearing seat 25 are grooves, and the limiting structures 27 on the sleeve 24 are protrusions that respectively cooperate with the grooves of the stator 23 and bearing seat 25 on both sides.

[0046] By setting a corresponding circumferential limiting structure 27 at the connection of the stator 23, sleeve 24 and bearing seat 25 of the drive unit 2, the installation of the drive unit 2 is simplified, and the drive unit 2 is provided with a separate housing 20, making it an independent module.

[0047] like Figure 2-4 As shown, the drive unit 2 is also equipped with a travel limit device 28 and a brake device 29. The travel limit device 28 is disposed within the bearing housing 25, and the brake device 29 is disposed within the sleeve 24. The travel limit device 28 includes: a Hall element 281, which is mounted on the bearing housing 25 and disposed on the side of the output shaft 21, and is electrically connected to the control unit 4. A pressure cap 282 is mounted on the outside of the Hall element 281 to axially fix it to the bearing housing 25; and a magnetic element 283, which is sleeved on the output shaft 21 and is disposed corresponding to the Hall element 281. An up / down travel limit key is provided at the control unit 4. When the user is using the device, the Hall element can record the real-time number of revolutions. After adjusting to the appropriate number of revolutions, pressing the up / down travel limit key can limit the up / down travel of the drive unit 2. The drive unit 2 will automatically stop and brake when it rotates to the limited number of up / down revolutions.

[0048] The braking device 29 includes a brake upper cover 291 and a brake lower cover 292 coaxially sleeved outside the output shaft 21, and a friction plate 293 sandwiched between the brake upper cover 291 and the brake lower cover 292. The friction plate 293 is circumferentially limited by the outer cover 24. When the motor stops, the brake upper cover 291 and the brake lower cover 292 will squeeze the friction plate 293 under the action of the elastic element to achieve the braking effect.

[0049] By setting the travel limit device 28 and the braking device 29, the travel limit device 28 is an electronic limit, which is not limited in the number of travel circles compared to the mechanical limit. This ensures that the travel can be accurately controlled when the motor is running and can be braked quickly when it stops, thus improving the accuracy and safety of the motor.

[0050] like Figure 5 , 6 As shown, the bearing housing 25 is connected to the transmission unit 3 during installation. The transmission unit 3 has several protruding structures 32 arranged around its circumference. The bearing housing 25 is provided with a mating groove 251 corresponding to the protruding structures 32, so that the drive unit 2 and the transmission unit 3 can be quickly positioned during installation.

[0051] like Figure 6As shown, the fixing sleeve 31 is circumferentially connected to the outer shell 1 to prevent misalignment. The outer shell 1 is provided with a positioning groove 12, and the fixing sleeve 31 is circumferentially provided with a first positioning part 312 that mates with the positioning groove 12. A height-fixing plate 5 is installed on the outer side of the fixing sleeve 31. The height-fixing plate 5 is provided with different height specifications, which can be selected according to the actual installation requirements. The height-fixing plate 5 has a plurality of positioning holes 51 and grooves 52 corresponding to the through holes 311. The outer end face of the fixing sleeve 31 is provided with a plurality of second positioning parts 313 that mate with the positioning holes 51.

[0052] By setting a protruding structure 32 in the transmission unit 3 to cooperate with the mating groove 251 set in the bearing seat 25 of the drive unit 2, circumferential positioning of the drive component 2 and the transmission component 3 is achieved; by cooperating the first positioning part 312 of the fixed sleeve 31 with the positioning groove 12 of the outer shell 1, and by cooperating the positioning hole 51 and groove 52 of the height plate 5 with the second positioning part 313 of the outer end face of the fixed sleeve 31, circumferential positioning between the outer shell 1, the transmission component 3 and the height plate 5 is achieved, ensuring the stability and reliability of the structure of this utility model.

[0053] like Figure 2 As shown, the drive unit 2 is an AC motor, and the transmission unit 3 is a planetary gearbox. When the utility model is finally assembled, the drive unit 2 and the transmission unit 3 have been assembled independently. The installation of the utility model can be quickly completed by simply installing the two into the outer casing 1 in sequence.

The difference between Embodiment 2 and Embodiment 1 is that: the output shaft 21 includes two output ends, and each output end is connected to a transmission unit 3 with the same transmission coefficient; the stroke limiting device 28 and the braking device 29 are respectively disposed on the output ends on both sides.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
