Description

Technical Field

[0001] This utility model relates to the field of roller shutter drive motor technology, specifically to a tubular motor. Background Technology

[0002] Tubular motors, as a common drive device, are widely used in the lifting and lowering control of roller blinds. They automate the operation of the roller blinds through their internal power transmission structure, bringing convenience to people's lives and work. During the production, debugging, and subsequent functional upgrades of tubular motors, it is often necessary to program or upgrade the PCB inside the motor. However, currently, most existing tubular motors have a one-piece casing. While this one-piece casing provides good protection for the internal components, preventing damage from external dust, moisture, and impacts, it causes significant inconvenience when PCB programming is required.

[0003] Since the casing is a single unit, exposing the internal PCB for programming requires disassembling the motor. Disassembly typically requires specialized tools and specific steps to remove fixed components from the casing. This not only consumes significant time and manpower, reducing operational efficiency, but frequent disassembly can also damage the motor casing and internal components, affecting the motor's structural stability and lifespan. Furthermore, for some already installed tubular motors, disassembly and programming further complicates the process and may even interfere with the normal operation of the roller shutter system.

[0021] This utility model provides a tubular motor, see [link]. Figures 1 to 5The tubular motor is mainly composed of three parts: the outer shell 100, the drive mechanism 200, and the circuit mechanism 300. These three parts work together to realize the driving function and related control operations of the motor.

[0022] The outer casing 100 serves as the basic load-bearing structure of the motor. It has an overall cylindrical structure and is composed of a first casing 110, a second casing 120, a connecting casing 130, and a programming cover 140. This integrated cylindrical structure design ensures the structural strength of the outer casing 100 and can adapt to the installation requirements of roller shutter drive scenarios.

[0023] The first housing portion 110 and the second housing portion 120 are both cylindrical structures with open ends and each has a hollow cavity. These two hollow cavities provide installation space for the key components of the drive mechanism 200, allowing the drive mechanism 200 to be stably integrated inside the housing 100. The connecting housing portion 130 is a cylindrical structure, with one end of the connecting housing portion 130 fixedly inserted into one end of the first housing portion 110, and the other end of the connecting housing portion 130 fixedly inserted into one end of the second housing portion 120. Through this fixed insertion connection method, the various parts of the housing 100 can be tightly combined to form a stable whole, effectively avoiding abnormal noise or performance fluctuations caused by structural loosening during motor operation.

[0024] The connecting shell 130 has an electrical cavity 131 inside, which is specifically used to house the circuit mechanism 300, creating a reasonable spatial separation between the circuit mechanism 300 and the drive mechanism 200 and reducing mutual interference. Simultaneously, the connecting shell 130 also has a programming opening 132, with the electrical cavity 131 communicating with the programming opening 132. This design provides the necessary operating channel for subsequent program programming and function debugging. Furthermore, the first shell 110 and the second shell 120 are respectively provided with clearance openings 133 at the corresponding locations of the programming openings 132. These clearance openings 133 make the connection structure between the first shell 110, the second shell 120, and the connecting shell 130 smoother, not only enhancing the overall structural compactness and reducing unnecessary space occupation, but also reducing stress concentration caused by structural abruptness, further improving the overall strength of the outer shell 100.

[0025] The drive mechanism 200 includes a motor 210, a first reducer 220, a second reducer 230, a first output shaft 240, and a second output shaft 250. In terms of installation position, the motor 210 and the first reducer 220 are disposed within the hollow cavity of the first housing 110, with the motor 210 positioned closer to the end of the connecting housing 130. The second reducer 230 is disposed within the hollow cavity of the second housing 120. The first output shaft 240 is mounted on the end of the first housing 110 furthest from the connecting housing 130, and the second output shaft 250 is mounted on the end of the second housing 120 furthest from the connecting housing 130. This layout fully utilizes the hollow cavities of the first housing 110 and the second housing 120, allowing the components of the drive mechanism 200 to be arranged in an orderly manner.

[0026] From the perspective of power transmission path, the first output end 211 of motor 210 is connected to the input end of first reducer 220, and the output end of first reducer 220 is connected to first output shaft 240; the second output end 212 of motor 210 is connected to the input end of second reducer 230, and the output end of second reducer 230 is connected to second output shaft 250. Since the specifications of first reducer 220 and second reducer 230 are identical, and the power output from the first output end 211 and second output end 212 of motor 210 is synchronized, the first output shaft 240 and second output shaft 250 can maintain synchronous rotation, thereby achieving synchronous drive of the curtains on both sides and ensuring the consistency of the curtains' raising and lowering. Through the action of first reducer 220 and second reducer 230, the power generated by motor 210 can be reduced in speed and increased in torque, and then output through first output shaft 240 and second output shaft 250 respectively, meeting the power requirements for driving the curtains and significantly improving the driving performance and applicability of the tubular motor. At the same time, the electrical connection terminal 213 of the motor 210 is electrically connected to the circuit mechanism 300 to ensure that the circuit mechanism 300 can effectively control the motor 210.

[0027] The circuit structure 300 includes several circuit boards 310, which are arranged in an orderly manner in the electrical cavity 131 of the connecting housing 130, saving space and facilitating the wiring connections between the circuit boards 310. One circuit board 310 is electrically connected to the electrical connection terminal 213 of the motor 210. This circuit board 310 provides stable control signals and electrical energy to the motor 210 and is a core component ensuring the normal and stable operation of the motor 210. In addition, one circuit board 310 is provided with a communication interface 311 facing the programming opening 132, and another circuit board 310 is provided with a debugging button 312, which also faces the programming opening 132. This design provides a convenient structural basis for programming and debugging operations, allowing operators to perform related operations directly through the programming opening 132.

[0028] The programming cover 140 is movably mounted on the programming opening 132 of the connecting housing 130. The programming cover 140 is snapped onto the programming through hole to seal the programming through hole and prevent external dust, moisture, etc. from entering the electrical cavity 131 and affecting the normal operation of the circuit mechanism 300. The programming cover 140 includes a cover part 141, a fastening part 142, and a button part 143. These parts work together to ensure both a sealing effect and convenient operation.

[0029] The cover portion 141 is in the shape of an arc plate and is adapted to the shape of the connecting shell portion 130. The cover portion 141 has a cover hole 1411 and a button hole 1412. The cover hole 1411 is connected to the electrical cavity 131. During operation, the cover can be removed through the cover hole 1411. The inner side of the cover portion 141 is provided with a limiting strip 1413 and a reinforcing rib 1414. The limiting strip 1413 is arranged along the circumference of the shell, and the reinforcing rib 1414 extends along the circumference of the shell. These structures can enhance the strength of the cover portion 141, prevent the cover portion 141 from deforming due to external force, and ensure effective sealing of the programming opening 132. The fastening part 142 is located inside the cover part 141. The fastening part 142 consists of two fastening straight plates 1421 and a fastening protrusion 1422. The fastening protrusion 1422 is located on the outer side of the fastening straight plates 1421 and is engaged with the opposite sides of the programming through hole. During assembly, the fastening part 142 of the programming cover part 140 is engaged into the electrical cavity 131 to complete the fixation. This snap-fit ​​method allows the installation and removal of the programming cover part 140 without additional tools, making the operation convenient. During programming, only the programming cover part 140 needs to be removed first, which greatly improves the operating efficiency.

[0030] The button part 143 is provided on the button hole 1412. The button part 143 is opposite to the debugging button 312 of the circuit mechanism 300. When debugging, pressing the button part 143 will squeeze the debugging button 312. The button part 143 is made of rubber and includes a limiting part 1431, a connecting part 1432, and a pressing part 1433. The limiting part 1431 is connected to one end of the connecting part 1432, and the pressing part 1433 is connected to the other end of the connecting part 1432. The size of the limiting part 1431 and the pressing part 1433 is larger than the button hole 1412, thereby limiting the button part 143. The connecting part 1432 passes through the button hole 1412, the limiting part 1431 is located inside the burning opening 132, and the pressing part 1433 abuts against the outside of the cover part 141. The side of the limiting part 1431 facing the adjustment button 312 is provided with an annular groove 1434 and a protrusion 1435. The annular groove 1434 surrounds the adjustment button 312, and the protrusion 1435 contacts the adjustment button 312. The rubber button part 143 is elastic, which can provide operators with good tactile feedback, while avoiding damage to the adjustment button 312 by direct pressing.

[0031] In summary, addressing the issue that existing tubular motors, with their integral housing structure, require disassembly for programming, leading to complex operations and inconvenient upgrades, this utility model's tubular motor, through a rational structural design, integrates the drive mechanism and circuitry within a robust housing. Specifically, the clever design of the programming opening connecting the housing and the programming cover eliminates the need for complete disassembly; programming can be performed simply by removing the programming cover. Debugging can also be completed directly via the button area. Furthermore, this motor enables synchronous driving of curtains on both sides, ensuring consistent raising and lowering. This not only guarantees the motor's driving performance but also effectively solves the problems existing in the prior art, achieving convenient programming and easy debugging, improving operational efficiency during production and maintenance, and enhancing the motor's market competitiveness.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
