Description

Technical Field

[0001] This application relates to the technical field of electrical equipment, and in particular to a plastic-sealed fan coil motor. Background Technology

[0002] In modern air conditioning systems, the fan coil unit motor is one of the core components, and its performance and stability play a crucial role in the overall system's operating efficiency and reliability. Typically, the capacitor box is connected and fixed to the motor body via slots or screws.

[0003] However, when using a slot-fixed method, the fan coil motor is in a state of constant vibration during operation, and the fit between the slot and the capacitor box is prone to slippage or displacement due to vibration, resulting in an unstable connection between the capacitor box and the motor.

[0004] While using screws for fixing is relatively stable, it usually requires four screws to ensure the capacitor box is secure. Typically, two to four people are assigned to the screw-driving process, which increases the assembly steps and time costs in the production process, and the connection efficiency between the motor and the capacitor box is relatively low. Utility Model Content

[0005] To address the shortcomings of existing motor-capacitor box connections, this application provides a plastic-sealed fan coil motor.

[0006] The technical solution for a plastic-sealed fan coil motor provided in this application is as follows:

[0007] A plastic-sealed fan coil motor, comprising:

[0008] The body includes a plastic-encapsulated stator. Two axially parallel limiting ribs are provided on the outer periphery of the plastic-encapsulated stator. Slots are provided on opposite sides of the limiting ribs. An integrally formed thickened part is also provided on the outer periphery of the plastic-encapsulated stator. The thickened part is provided with a first threaded hole. A positioning screw is provided on the side of the plastic-encapsulated stator away from the limiting ribs.

[0009] The capacitor box is detachably connected to the plastic-encapsulated stator. It has inserts on both sides that match the limiting ribs, and a protrusion on one side that corresponds to the thickened part. The protrusion has a second threaded hole that is opposite to the first threaded hole. The second threaded hole is opposite to the first threaded hole. The side of the capacitor box away from the inserts has a strip-shaped opening that matches the positioning screw.

[0010] By adopting the above technical solution, the outer periphery of the plastic-encapsulated stator is provided with two axially parallel limiting ribs, which can provide positioning and support for the capacitor box. The opposite sides of the limiting ribs are provided with slots that match the inserts on the capacitor box, which can quickly and accurately connect the capacitor box to the plastic-encapsulated stator and achieve initial positioning of the capacitor box. The thickened part can provide additional structural strength to support the positioning screws. The thickened part is provided with a first threaded hole that mates with a second threaded hole on the capacitor box, which can further fix the capacitor box by screw connection, ensuring that the capacitor box will not loosen during operation, thereby improving the positional stability of the capacitor box. The side of the plastic-encapsulated stator away from the limiting ribs is provided with positioning screws, which can mate with the strip opening on the capacitor box to further restrict the movement of the capacitor box, ensuring that the capacitor box can be accurately positioned during installation and avoiding assembly problems caused by positional deviation. By combining slot fixing and screw fixing, the capacitor box can be prevented from sliding or shifting due to vibration. And by fixing the capacitor box with a small number of screws (two), the connection efficiency between the motor and the capacitor box can be improved, and the existing defects in the connection between the motor and the capacitor box can be improved.

[0011] Preferably, a cylindrical protrusion is provided on one side of the machine body, the cylindrical protrusion is coaxially arranged with the output shaft of the machine body, a connecting ring is sleeved on the cylindrical protrusion, a limit block is provided on the outer wall of the cylindrical protrusion, and a first groove matching the limit block is opened on the inner wall of the connecting ring.

[0012] By adopting the above technical solution, the limiting ring is sleeved on the cylindrical protrusion, which can improve the structural strength of the machine body, limit the position and vibration of the machine body, and prevent the machine body from deflecting or moving. The limiting block matches the first groove, which can conveniently sleeve the limiting ring on the cylindrical protrusion, prevent the connecting ring from rotating circumferentially after installation, thereby ensuring that the relative position between the connecting ring and the cylindrical protrusion is fixed.

[0013] Preferably, the outer wall of the connecting ring is provided with a second groove.

[0014] By adopting the above technical solution, the second groove can be used to install other external components, such as fixed sleeves, sealing rings or brackets, and to achieve axial and circumferential positioning of these structures or components, ensuring that these structures or components remain stable during operation and will not loosen or shift, thus meeting more complex assembly requirements of the motor.

[0015] Preferably, it also includes a support frame, which includes a horizontal part and a vertical part, the horizontal part and the vertical part are integrally formed, the end of the vertical part away from the horizontal part is provided with an arc-shaped notch that matches the second groove, and both sides of the vertical part are provided with barbs.

[0016] By adopting the above technical solution, the support frame is connected to any plane through the horizontal part, and the vertical part cooperates with the connecting ring to form a stable support structure, preventing the connecting ring from shaking or displacing during operation, thereby restricting the position of the body and reducing the shaking and / or displacement of the body during operation. The cooperation between the arc-shaped notch and the second groove can disperse the radial force received by the connecting ring, avoid damage caused by stress concentration, and thus extend the service life of the limiting ring; the barb part enables the support frame to be quickly snapped onto the external structure without using screws or other fasteners, greatly simplifying the installation process, improving production efficiency. The snap connection structure is also convenient for disassembly and maintenance, allowing the support frame or other components to be quickly replaced, reducing maintenance costs and time.

[0017] Preferably, it further includes a connecting piece. The connecting piece includes an integrally formed first connecting part, second connecting part, third connecting part, and a through groove matching the barb part. The first connecting part is provided with a first through hole for accommodating a bolt. One end of the second connecting part is connected to one end of the first connecting part. The second connecting part is arc-shaped, and a convex block for being snapped into the second groove is provided on the inner arc surface of the second connecting part. One end of the third connecting part is connected to the end of the second connecting part far from the first connecting part. The through groove is provided at the end of the second connecting part far from the first connecting part, and the end of the through groove far from the first connecting part extends to the end of the third through groove close to the second connecting part.

[0018] By adopting the above technical solution, the first connecting part of the connecting piece is provided with a first through hole, enabling the connecting piece to be connected to other components through the first through hole and the bolt. The second connecting part of the connecting piece is provided with a convex block for being snapped into the second groove, enabling the connecting piece to be connected to the connecting ring and form a whole. The second part and the third part of the connecting piece are provided with through grooves, and the through grooves match the barb part, enabling the connecting piece to be further connected to the support frame. Thus, the support frame and the connecting ring can be connected through the connecting piece, making the support frame and the connecting ring form a whole. Thereby, the body is fixed on any horizontal plane through the support frame, and the connecting ring and the body connected to the connecting ring are prevented from having radial displacement or shaking during operation, improving the operation stability.

[0019] Preferably, the connecting rod is in a "冂" shape, and second through holes are provided at both ends of the connecting rod. The specifications of the second through holes are the same as those of the first through holes.

[0020] By adopting the above technical solution, the connecting rod is in a "冂" shape, similar to an open rectangular frame with both ends extending outwards, enabling the connecting rod to be connected to other components at both ends respectively, while providing a certain support or space in the middle part to meet different assembly requirements; the specifications of the second through holes are the same as those of the first through holes, and the connecting rod can be connected to the component (connecting piece) with the first through hole using bolts of the same specification, preventing the loosening or displacement of the connecting piece and ensuring stability.

[0021] Preferably, the outer periphery of the plastic-encapsulated stator is also provided with several protruding heat sinks.

[0022] By adopting the above technical solution, the heat sink and the plastic-encapsulated stator are integrally molded, which can quickly conduct heat from the inside of the stator to the surface of the heat sink. By increasing the contact area between the plastic-encapsulated stator and the air, the heat transfer is accelerated, thereby reducing the temperature of the plastic-encapsulated stator, improving the operational stability of the machine, preventing the plastic-encapsulated stator from being damaged due to overheating during high load or long-term operation, enabling the machine to operate stably within a wider load range, reducing the risk of failure due to overheating, and extending the service life of the machine.

[0023] Preferably, the outer periphery of the plastic-encapsulated stator is also provided with an outlet for leading out wires.

[0024] By adopting the above technical solution, the outlet makes it easier to lead out and connect the wires, simplifies the assembly process, and allows the wires to be quickly and accurately connected to the motor capacitor or other external circuits through the pre-designed outlet, avoiding wire mess and facilitating installation and maintenance.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The outer periphery of the plastic-encapsulated stator is provided with two axially parallel limiting ribs, which provide positioning and support for the capacitor box. Slots matching the inserts on the capacitor box are provided on opposite sides of the limiting ribs, enabling quick and accurate connection between the capacitor box and the plastic-encapsulated stator, achieving initial positioning of the capacitor box. The thickened section provides additional structural strength to support the positioning screws. A first threaded hole on the thickened section mates with a second threaded hole on the capacitor box, allowing for further fixation of the capacitor box via screw connection, ensuring the capacitor box does not loosen during operation and improving its positional stability. Positioning screws are located on the side of the plastic-encapsulated stator away from the limiting ribs, mate with the strip-shaped opening on the capacitor box, further restricting the movement of the capacitor box and ensuring accurate positioning during installation, avoiding assembly problems caused by positional deviations. By combining slot fixing and screw fixing, the capacitor box is prevented from sliding or shifting due to vibration. Furthermore, fixing the capacitor box with only two screws improves the connection efficiency between the motor and the capacitor box, addressing certain defects in existing motor-capacitor box connections.

[0027] 2. The limiting ring is fitted onto the cylindrical protrusion, which can improve the structural strength of the machine body, limit the position and vibration of the machine body, and prevent the machine body from deflecting or moving. The limiting block matches the first groove, which can easily fit the limiting ring onto the cylindrical protrusion, preventing the connecting ring from rotating circumferentially after installation, thereby ensuring that the relative position between the connecting ring and the cylindrical protrusion is fixed.

[0028] 3. The second groove can be used to install other external components, such as fixed sleeves, sealing rings or brackets, and to achieve axial and circumferential positioning of these structures or components, ensuring that these structures or components remain stable during operation and do not loosen or shift, thus meeting more complex assembly requirements of the motor.

Detailed Implementation

[0040] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0041] This application discloses a plastic-encapsulated fan coil unit motor. (Refer to...) Figure 1 and Figure 2 The encapsulated fan coil motor includes a body 1, a capacitor box 2, a connecting ring 3, a support frame 4, a connecting piece 5, and a connecting rod 8.

[0042] like Figure 3 and Figure 4 As shown, the body 1 includes a plastic-encapsulated stator 11, which is fixedly disposed on the outer periphery of the body 1. Two axially parallel limiting ribs 111 are provided on the outer periphery of the plastic-encapsulated stator 11. Slots 112 are provided on opposite sides of the limiting ribs 111. An integrally formed thickened part 113 is also provided on the outer periphery of the plastic-encapsulated stator 11. The thickened part 113 is provided with a first threaded hole 114. A positioning screw 115 is provided on the side of the plastic-encapsulated stator 11 away from the limiting ribs 111. The capacitor box 2 is detachably connected to the plastic-encapsulated stator 11. Inserts 21 that match the limiting ribs 111 are provided on both sides. A protrusion 22 corresponding to the thickened part 113 is provided on one side. A second threaded hole 23 corresponding to the first threaded hole 114 is provided on the protrusion 22. The second threaded hole 23 is positioned opposite to the first threaded hole 114. A strip-shaped opening 24 that matches the positioning screw 115 is provided on the side of the capacitor box 2 away from the inserts 21.

[0043] In this embodiment, the capacitor box 2 is used to house the capacitor to prevent damage from external impacts. Two parallel axially arranged limiting ribs 111 are provided on the outer periphery of the plastic-encapsulated stator 11, providing positioning and support for the capacitor box 2. Slots 112 matching the inserts 21 on the capacitor box 2 are provided on opposite sides of the limiting ribs 111, enabling quick and accurate connection of the capacitor box 2 to the plastic-encapsulated stator 11, achieving initial positioning of the capacitor box 2. The thickened portion 113 provides additional structural strength to support the positioning screws 115. The support and thickened part 113 are provided with a first threaded hole 114 that mates with a second threaded hole 23 on the capacitor box 2. The capacitor box 2 can be further fixed by screw connection to ensure that the capacitor box 2 will not loosen during operation, thereby improving the positional stability of the capacitor box 2. The plastic-encapsulated stator 11 is provided with a positioning screw 115 on the side away from the limiting rib 111. It can mate with the strip opening 24 on the capacitor box 2 to further restrict the movement of the capacitor box 2, ensuring that the capacitor box 2 can be accurately positioned during installation and avoiding assembly problems caused by positional deviation.

[0044] Specifically, during installation, the insert 21 of the capacitor box 2 is first inserted into the slot 112 of the limiting rib 111 of the plastic-encapsulated stator 11 to initially limit the position of the capacitor box 2 relative to the plastic-encapsulated stator 11. Then, the positioning screw 115 is set to connect the side of the capacitor box 2 away from the limiting rib 111 to the plastic-encapsulated stator 11. Finally, the screw is passed through the first threaded hole 114 and the second threaded hole 23 to further fix the capacitor box 2 and the plastic-encapsulated stator 11. By combining the fixing with the slot 112 and the screw, the capacitor box 2 can be prevented from sliding or shifting due to vibration. By fixing the capacitor box 2 with a small number of screws (two), the installation of the plastic-encapsulated stator 11 and the capacitor box 2 can be completed by a single person, improving the connection efficiency between the motor and the capacitor box 2 and improving the existing defects in the connection between the motor and the capacitor box 2.

[0045] like Figure 5 and Figure 6 As shown in this embodiment, a cylindrical protrusion 12 is provided on one side of the body 1. The cylindrical protrusion 12 is coaxially arranged with the output shaft of the body 1. A connecting ring 3 is sleeved on the cylindrical protrusion 12. A limiting block 13 is provided on the outer wall of the cylindrical protrusion 12. The limiting block 13 is strip-shaped and integrally formed with the cylindrical protrusion 12. A first groove 31 matching the limiting block 13 is opened on the inner wall of the connecting ring 3, and a second groove 32 is provided on the outer wall of the connecting ring 3. For example, the connecting ring 3 is a metal ring. The limiting ring sleeved on the cylindrical protrusion 12 can improve the structural strength of the body 1 and limit the position of the body 1. To limit the vibration of the machine body 1 and prevent the machine body 1 from deflecting or moving, the limiting block 13 matches the first groove 31, which can conveniently fit the limiting ring onto the cylindrical protrusion 12, preventing the connecting ring 3 from rotating circumferentially after installation, thereby ensuring that the relative position between the connecting ring 3 and the cylindrical protrusion 12 is fixed. The second groove 32 can be used to install other external components, such as fixed sleeves, sealing rings or brackets, and to achieve axial and circumferential positioning of these structures or components, ensuring that these structures or components remain stable during operation and will not loosen or shift, thus meeting more complex assembly requirements of the motor.

[0046] like Figure 7As shown, the support frame 4 includes a horizontal part 41 and a vertical part 42, which are integrally formed. The vertical part 42 has an arc-shaped notch 43 that matches the second groove 32 at one end away from the horizontal part 41. Both sides of the vertical part 42 are provided with barbs 44. For example, the support frame 4 is a metal bracket. The support frame 4 is connected to any plane through the horizontal part 41. The vertical part 42 cooperates with the connecting ring 3 to form a stable support structure, preventing the connecting ring 3 from shaking or displacing during operation, thereby limiting the position of the machine body 1 and reducing the shaking and / or displacement of the machine body 1 during operation. The cooperation between the arc-shaped notch 43 and the second groove 32 can disperse the radial force on the connecting ring 3, avoid damage caused by stress concentration, and thus extend the service life of the limiting ring. The barbs 44 allow the support frame 4 to be quickly snapped onto the external structure without the need for screws or other fasteners, which greatly simplifies the installation process and improves production efficiency. The snap-fit ​​structure is also easy to disassemble and maintain, and the support frame 4 or other parts can be quickly replaced, reducing maintenance costs and time.

[0047] like Figure 8 As shown, the connecting piece 5 includes an integrally formed first connecting part 51, a second connecting part 52, a third connecting part 53, and a through groove 56 that matches the barb part 44. The first connecting part 51 has a first through hole 54 for accommodating a bolt. One end of the second connecting part 52 is connected to one end of the first connecting part 51. The second connecting part 52 is arc-shaped. The inner arc surface of the second connecting part 52 is provided with a protrusion 55 for engaging the second groove 32. One end of the third connecting part 53 is connected to the end of the second connecting part 52 away from the first connecting part 51. The through groove 56 is located at the end of the second connecting part 52 away from the first connecting part 51, and the end of the through groove 56 away from the first connecting part 51 extends to the end of the third through groove 56 near the second connecting part 52.

[0048] For example, in this embodiment of the application, the connecting piece 5 is a metal sheet; the first connecting part 51 of the connecting piece 5 is provided with a first through hole 54, so that the connecting piece 5 can be connected to other components through the first through hole 54 and bolts; the second connecting part 52 of the connecting piece 5 is provided with a protrusion 55 that fits into the second groove 32, so that the connecting piece 5 can be connected to the connecting ring 3 and form an integral whole; the second part and the third part of the connecting piece 5 are provided with through grooves 56, which match the barb part 44, so that the connecting piece 5 can also be connected to the support frame 4, thereby connecting the support frame 4 and the connecting ring 3 through the connecting piece 5, so that the support frame 4 and the connecting ring 3 form an integral whole, thereby fixing the body 1 on any horizontal plane through the support frame 4, and preventing the connecting ring 3 and the body 1 connected by the connecting ring 3 from radial displacement or shaking during operation, thus improving operational stability.

[0049] like Figure 9As shown in this embodiment, the connecting rod 8 is U-shaped, and both ends of the connecting rod 8 are provided with second through holes 9. The second through holes have the same specifications as the first through hole 54. For example, the connecting rod 8 is a metal rod, and the connecting rod 8 is U-shaped, similar to an open rectangular frame, with both ends extending outward, so that the connecting rod 8 can be connected to other components at both ends, while providing a certain support or space in the middle part to meet different assembly requirements. The specifications of the second through hole 9 are the same as those of the first through hole 54. The connecting rod 8 can be connected to the component (connecting piece 5) with the first through hole 54 using bolts of the same specifications to prevent the connecting piece 5 from loosening or shifting and to ensure stability.

[0050] It should be noted that in this embodiment of the application, the body 1 is configured with a dual-shaft extension, that is, the sealing fan coil motor is a dual-shaft motor, and output ends are provided on both sides of the body 1. Cylindrical protrusions 12, connecting rings 3, connecting pieces 5 and connecting rods 8 are provided on both sides of the body 1, and a support frame 4 is provided below the body 1.

[0051] For details, please refer to Figure 7 and Figure 10 The support frame 4 has two vertical parts 42, which are respectively located on both sides of the body 1. Each vertical part 42 is connected to the corresponding connecting ring 3, and the two barbs 44 of each vertical part 42 are connected to the corresponding connecting piece 5. The first connecting parts 51 of the two connecting pieces 5 located on the same side of the body 1 abut against each other, and the first connecting part 51 of one of the connecting pieces 5 abuts against one end of the connecting rod 8. The corresponding ends of the two connecting pieces 5 located on the same side of the body 1 and the connecting rod 8 are connected by screws passing through the first through hole 54 and the second through hole 9. That is, the connecting pieces 5 on both sides of the body 1 are connected by the connecting rod 8, so that the support frame 4 and the body 1 are connected to form a whole, ensuring the stability of the body 1 during operation. In addition, the connecting ring 3, connecting piece 5 and connecting rod 8 ensure a stable connection between the body 1 and the support frame 4, and facilitate the installation and disassembly of the body 1, thereby facilitating the maintenance and replacement of the body 1 and reducing the workload of maintenance and replacement of the body 1.

[0052] like Figure 1As shown, the outer periphery of the plastic-encapsulated stator 11 is also provided with several protruding heat sinks 6. For example, the several protruding heat sinks 6 are arranged in parallel on the outer periphery of the plastic-encapsulated stator 11 to optimize the airflow path and enhance the convective heat dissipation effect. The heat sinks 6 are integrally formed with the plastic-encapsulated stator 11, which can quickly conduct heat from the inside of the stator to the surface of the heat sinks 6. By increasing the contact area between the plastic-encapsulated stator 11 and the air, the heat transfer is accelerated, thereby reducing the temperature of the plastic-encapsulated stator 11, improving the operational stability of the machine body 1, preventing the plastic-encapsulated stator 11 from being damaged due to overheating when the machine body 1 is under high load or running for a long time, enabling the machine body 1 to operate stably within a wider load range, reducing the risk of failure due to overheating, and extending the service life of the machine body 1.

[0053] like Figure 1 and Figure 2 As shown, the outer periphery of the plastic-encapsulated stator 11 is also provided with an outlet 7 for leading out wires; for example, the outlet 7 is arranged opposite to the capacitor box 2. The outlet 7 makes it easier to lead out and connect wires, simplifies the assembly process, and allows wires to be quickly and accurately connected to the motor capacitor or other external circuits through the pre-designed outlet 7, avoiding wire mess and facilitating installation and maintenance.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
