Description
Technical Field
[0001] This utility model relates to the field of power motor technology, and in particular to a power motor. Background Technology
[0002] In the traditional field of motor design and application, structural layout, environmental adaptability, and ease of maintenance have always been key issues restricting performance improvement and technological development. Conventional motors often employ a distributed arrangement of drive, transmission, and control units, resulting in excessively large overall axial dimensions and low space utilization, making it difficult to meet the miniaturization and lightweight requirements of modern compact electromechanical systems. Furthermore, this structure is prone to coaxiality deviations due to accumulated assembly errors, affecting transmission smoothness and increasing vibration and noise. Under harsh operating conditions, insufficient sealing design allows dust and moisture to penetrate the motor, leading to control unit and transmission component failure and reducing system reliability. In addition, the control unit is usually separated from the motor body or fixed in a location that is difficult to disassemble; once a failure occurs, extensive disassembly and reassembly work is required, resulting in low maintenance efficiency and high costs. While some modular design solutions exist in existing technologies, most fail to achieve efficient integration and rapid maintenance of drive, control, and transmission functions, making it difficult to balance structural compactness with environmental protection and ease of maintenance. Therefore, a new type of motor structure is urgently needed to optimize spatial layout, improve sealing performance, and simplify maintenance processes, thereby adapting to more demanding industrial application scenarios.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-6As shown, in one embodiment of this utility model, a power motor is provided, including a housing 1, a first base 2, a transmission assembly 3, a second base 4, a drive motor 5, a control board 6, and a control connection line 7. The housing 1 is provided with a mounting cavity 8, and the mounting cavity 8 is provided with a drive mounting part 81, a transmission connection part 82, and a sealing connection part 83 arranged sequentially from the inside to the outside.

The side of the second base 4 facing the first base 2 is provided with a mounting platform 41, and the control board 6 is disposed on the mounting platform 41. The control connection line 7 is electrically connected to the control board 6. This embodiment provides a clear and precise positioning and installation foundation for the drive motor 5, the transmission assembly 3, and the sealing element by sequentially arranging the drive mounting part 81, the transmission connection part 82, and the sealing connection part 83 from the inside to the outside in the mounting cavity 8 of the housing 1. The layered layout ensures coaxiality and relative positional accuracy between functional units, reduces accumulated assembly errors, and helps guarantee the smoothness and reliability of power transmission, while reducing operating vibration and noise. The sealed connection 83, combined with the rotating connection element 84 and reliably connected to the first base 2, forms an effective sealing barrier. This structure prevents external dust, moisture, oil, and other contaminants from intruding into the core area of the motor, protecting the control board 6, drive motor 5, and transmission components 3, thus improving the long-term operational reliability and service life of the motor in harsh industrial environments. The control board 6 is directly mounted on the mounting platform 41 of the second base 4, integrating the control unit and drive motor 5 into the second base 4, forming an independent, detachable functional module. This design greatly facilitates the installation, debugging, testing, and replacement of the control unit. If a fault occurs in the control section, the module can be quickly repaired or replaced without extensive disassembly of the motor body or transmission system, improving maintenance efficiency and reducing maintenance costs and time. The control board 6 is mounted close to the second base 4 where the drive motor 5 is located, shortening the electrical distance to the controlled object. This not only saves internal space and makes the structure more compact, but also helps reduce signal interference and transmission loss. The control connection line 7 is directly connected to the control board 6 on the integrated module, with a clear wiring layout and reliable connection. This embodiment improves the structural rationality, environmental protection level, ease of use and maintenance, and operational reliability of the power motor, exhibiting excellent overall performance and possessing good practical value and market application prospects.
[0020] The outer periphery of the outer casing 1 is provided with a mounting connection portion 11, and the outer periphery of the mounting connection portion 11 is provided with mounting ribs 12. Multiple mounting ribs 12 are provided and are evenly distributed circumferentially around the outer periphery of the mounting connection portion 11. Mounting holes 121 are provided at both ends of each mounting rib 12. In this embodiment, the mounting connection portion 11 is provided on the outer periphery of the outer casing 1, and multiple mounting ribs 12 are evenly distributed circumferentially around the outer periphery of the mounting connection portion 11, with mounting holes 121 at both ends of the ribs. The evenly distributed circumferential mounting ribs 12 greatly enhance the connection rigidity and overall structural stability between the outer casing 1 and external equipment or mounting base, effectively resisting multidimensional vibrations and torques generated during motor operation and preventing loosening of the connection. As a reinforcing structure, the mounting ribs 12 optimize the load distribution at the mounting location, avoid stress concentration, and improve the deformation resistance and fatigue life of the outer casing 1 under complex working conditions.
[0021] A connecting step 831 is provided between the sealing connection part 83 and the transmission connection part 82. The rotating connecting element 84 is disposed on the connecting step 831. A fixing ring 841 is provided on one side of the rotating connecting element 84. The fixing ring 841 is used to fix the rotating connecting element 84. A sealing element 842 is provided on one side of the fixing ring 841. The sealing element 842 is used to seal between the first base 2 and the outer shell 1. In this embodiment, a connecting step 831 is provided between the sealing connection part 83 and the transmission connection part 82, and the rotating connecting element 84 is installed on the step and axially fixed by a retaining ring 841. At the same time, a sealing element 842 is provided on one side of the retaining ring, providing a precise and stable axial and radial positioning reference for the rotating connecting element 84, effectively ensuring its alignment accuracy and connection reliability with the first base 2, and preventing displacement due to vibration during operation. The retaining ring 841 realizes reliable locking of the rotating connecting element 84, which is convenient for installation and removal, avoids the problems of stripping or loosening that may occur in threaded connections, and improves maintenance efficiency. The sealing element 842 forms an effective static sealing barrier between the first base 2 and the outer shell 1, which enhances the sealing performance of the connection interface, effectively isolates external dust, moisture and other pollutants from entering the transmission cavity, protects the transmission component 3 and bearings, and extends the service life and operational reliability of the motor in harsh environments.
[0022] See Figures 3-4As shown, the outer casing 1 is provided with a second wiring hole 13, which is located on one side of the outer casing 1. One end of the control connection cable 7 passes through the second wiring hole 13 and connects to the control board 6. Specifically, a second fixing sleeve 131 is provided on the second wiring hole 13, which is used to fix the control connection cable 7. In this embodiment, a second wiring hole 13 is provided on the side wall of the outer casing 1, through which the control connection cable 7 passes and connects to the internal control board 6. Simultaneously, a second fixing sleeve 131 is provided at the wiring hole, providing a dedicated and centralized entry channel for the external control connection cable 7. This avoids the problems of weak sealing and messy appearance caused by multiple cables being scattered throughout the wiring, improving the overall neatness and professionalism of the equipment. The second fixing sleeve 131 can effectively clamp and position the passing control connection cable 7, preventing the cable from shifting, loosening, or even falling off due to equipment vibration or external pulling, ensuring the long-term reliability of the electrical connection. At the same time, the fixing sleeve structure provides a foundation for subsequent sealant filling, facilitating the formation of a uniform and dense sealing layer. This effectively seals the assembly gap between the cable and the wiring hole, significantly enhancing the protection level of the outer casing 1, preventing external moisture, dust, and other contaminants from entering the motor through the cable inlet, protecting key components such as the internal control board 6, and improving the motor's adaptability and operational stability in harsh industrial environments such as humid and dusty conditions.
[0023] A connecting bracket 23 is provided between the first base 2 and the second base 4. The control board 6 is located below the connecting bracket 23. The second base 4 is located on the upper side of the mounting platform 41 and is provided with a fixed mounting platform 42. The connecting bracket 23 is set on the fixed mounting platform 42. In this embodiment, by setting a connecting bracket 23 between the two bases, the control board 6 is arranged below it, and the bracket is installed on the fixed mounting platform 42 on the upper side of the second base 4, providing an independent and stable mounting platform 41 and physical support. This decouples the control board 6 from the vibration source of the motor body to a certain extent, effectively reducing the direct transmission of vibration from the motor to the control board 6 during operation, reducing the risk of damage to precision electronic components (such as chips and solder joints) on the board, and improving the reliability and service life of the control system. The raised installation position keeps the control board 6 away from the mounting platform 41, avoiding direct corrosion from ground contaminants such as water and oil, and enhancing its protective capabilities. The cooperation between the connecting bracket 23 and the fixed mounting platform 42 enables modular installation, with a compact structure and clear layout. This not only facilitates the individual assembly, debugging, and subsequent maintenance of the control board 6, but also optimizes the internal space utilization of the motor, which is beneficial to the miniaturization design of the whole machine.
[0024] See Figures 5-6As shown, a first wiring hole 21 is provided on the end face of the first base 2. One end of the first wiring hole 21 passes through the first base 2, and one end of the control connection line 7 passes through the first wiring hole 21 and connects to the control board 6. Specifically, a first fixing sleeve 211 is provided on the first wiring hole 21. The first fixing sleeve 211 is used to fix the control connection line 7 and seals the gap by filling with glue. In this embodiment, a through-hole 21 is provided on the end face of the first base 2, through which the control connection cable 7 passes and connects to the control board 6. Simultaneously, a first fixing sleeve 211 is provided at the cable hole, and the gap is sealed with glue, providing a dedicated and protected internal wiring channel for the control connection cable 7. This avoids messy cable arrangement within the housing, effectively preventing interference, wear, or detachment with moving parts, and improving the standardization and reliability of the wiring layout. The first fixing sleeve 211 effectively clamps and fixes the control connection cable 7, suppressing the risk of cable fretting or even breakage caused by equipment vibration. Sealing with glue forms a reliable static seal between the first fixing sleeve 211, the control connection cable 7, and the wall of the first cable hole 21, completely sealing the gap where the cable passes through the wall. This significantly enhances the sealing level, effectively preventing external moisture, dust, and other contaminants from entering the motor through the cable inlet, protecting precision electronic components such as the control board 6, and improving the motor's environmental adaptability and long-term operational stability under complex and harsh working conditions.
[0025] The first base 2 is provided with a fixed connection end 22, and the second base 4 is located on the upper side of the mounting platform 41 and is provided with a fixed mounting platform 42, which is connected to the fixed connection end 22. Specifically, the fixed connection end 22 is composed of multiple connecting ribs 221, and a fixed connection groove is formed between the multiple connecting ribs 221. The fixed mounting platform 42 is disposed on the fixed connection groove, and the connecting ribs 221 are provided with screws for connecting to the fixed mounting platform 42. In this embodiment, a stable and reliable mechanical connection between the first base 2 and the second base 4 is achieved by setting a fixed connection end 22 composed of multiple connecting ribs 221 on the first base 2 and a fixed mounting platform 42 adapted to the fixed connection groove on the second base 4, and then fastening the connection with screws. The multiple circumferentially distributed connecting ribs 221 and the formed connecting groove effectively increase the connection contact area and structural rigidity, improve the overall structural stability of the motor under operating vibration conditions, and prevent the connection from loosening or deforming due to long-term alternating stress. The layout design of the connecting ribs 221 optimizes the stress distribution, avoids local stress concentration, and improves the fatigue resistance and service life of the connection. The screw connection method provides sufficient connection preload, and the assembly process is simple, adjustable, and convenient for on-site installation and subsequent maintenance.
