Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor technology, and in particular to a multi-cavity shunt low-resistance wound external rotor permanent magnet motor. Background Technology

[0002] Permanent magnet motors, with their significant advantages such as high efficiency, energy saving, and high power density, have been widely used in many fields, including industrial production, transportation, and new energy equipment. External rotor permanent magnet motors, as an important type of permanent magnet motor, have a unique structural design that allows them to better adapt to certain specific transmission scenarios.

[0003] However, existing external rotor permanent magnet motors still face some problems in practical applications. In terms of installation, traditional external rotor permanent magnet motors typically use multiple bolts for installation, which is cumbersome, requiring significant manpower and time, and is extremely inconvenient for subsequent maintenance and disassembly, thus reducing overall operation and maintenance efficiency.

[0004] Therefore, this utility model provides a multi-cavity shunt low-resistance wound external rotor permanent magnet motor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-cavity shunt low-resistance external rotor permanent magnet motor, which solves the problem that the existing technology not only requires a lot of manpower and time costs, but is also extremely inconvenient in subsequent maintenance and disassembly, thus reducing the overall operation and maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides a multi-cavity shunt low-resistance external rotor permanent magnet motor, including a mounting plate. A protective component is provided on one side of the mounting plate. A convenient installation component is provided at the bottom of the protective component. The convenient installation component includes a support plate, and a lower protrusion is fixedly connected to the bottom of the support plate. A mating hole is opened inside the lower protrusion. The convenient installation component also includes a base. The lower protrusion is inserted into the interior of the base. An assembly block is fixedly connected between the inner walls of the base. A screw is rotatably connected inside the assembly block. A nut sleeve is threadedly connected to the outer wall of the screw. A pin is fixedly connected to one side of the nut sleeve. The pin is inserted into the interior of the mating hole.

[0007] The nut sleeve is rectangular in shape and is slidably connected to the inner wall of the base. The rectangular shape design can effectively prevent the nut sleeve from rotating with the screw and ensure its stable linear movement.

[0008] One end of the screw has a hexagonal socket, into which a hexagonal wrench can be inserted, allowing the operator to easily turn the screw and improving the ease of operation.

[0009] The protective component includes a permanent magnet motor body, the output shaft of which passes through a mounting plate to ensure that the permanent magnet motor body can output power normally.

[0010] The mounting plate is fixedly connected to one side of a positioning rod, and there are four positioning rods located at the four corners of the mounting plate. The protective assembly also includes a protective shell, which is cylindrical in shape. The positioning rods can be inserted into the side wall of the protective shell. The four positioning rods can accurately position the protective shell and ensure the connection accuracy between the protective shell and the mounting plate.

[0011] The protective shell has four adhesive pieces fixedly connected to the outer wall of one end. The protective assembly also includes bolts, which are threadedly connected to the adhesive pieces and the mounting plate. The bolts securely fix the protective shell to the mounting plate, thus improving the stability of the protective structure.

[0012] The inner wall of the protective shell is fixedly connected to an arc-shaped stabilizing block, and the inner wall of the arc-shaped stabilizing block is fixedly connected to a shock-absorbing sponge pad that contacts the outer wall of the permanent magnet motor body. The shock-absorbing sponge pad can effectively absorb the vibration generated by the permanent magnet motor body during operation and reduce the impact of vibration on the internal components of the motor. At the same time, the arc-shaped stabilizing block can support and stabilize the permanent magnet motor body.

[0013] The protective shell has a heat dissipation and dustproof cover threaded onto the inner wall of one end. The outer wall of the heat dissipation and dustproof cover has anti-slip texture. The heat dissipation and dustproof cover can not only ensure that the heat inside the motor is dissipated in time, but also prevent external dust and other debris from entering the motor. The anti-slip texture makes it easy for operators to install and remove the heat dissipation and dustproof cover, and facilitates subsequent cleaning and maintenance.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This multi-cavity shunt low-resistance external rotor permanent magnet motor features a convenient installation assembly. During installation, simply insert the lower protrusion into the base, then use a hex wrench to turn the screw, moving the nut sleeve and the pin to insert the pin into the mating hole, thus completing the quick installation of the motor. Disassembly is achieved by simply turning the screw in the opposite direction, greatly simplifying the installation and disassembly steps, improving work efficiency, and reducing labor and time costs.

[0015] 2. This multi-cavity shunt low-resistance external rotor permanent magnet motor effectively protects the main body of the permanent magnet motor through the protective shell in the protective assembly, preventing damage to the motor from impacts by external objects; at the same time, the shock-absorbing sponge pad on the inner wall of the arc-shaped stabilizing block can absorb the vibration generated during motor operation, ensuring the stability of the internal components of the motor and extending the service life of the motor.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Reference Figures 1 to 7This application provides a multi-cavity shunt low-resistance external rotor permanent magnet motor, including a mounting plate 1. A protective component 2 is provided on one side of the mounting plate 1. The protective component 2 is used to protect, dampen, dissipate heat, and prevent dust from the permanent magnet motor body 21. A convenient installation component 3 is provided at the bottom of the protective component 2, which is used to realize the quick installation and disassembly of the motor. The convenient installation component 3 includes a support plate 31, which is fixedly connected to the bottom of the protective component 2 to provide support for the protective component 2. A lower protrusion 32 is fixedly connected to the bottom of the support plate 31. The lower protrusion 32 has a mating hole 39 inside. The convenient installation component 3 also includes a base 38, which is pre-fixed in the installation position. The lower protrusion 32 is inserted into the interior of the base 38 to achieve initial positioning. An assembly block 33 is fixedly connected to the inner wall of the base 38, providing mounting support for the screw 34. The screw 34 is rotatably connected inside the assembly block 33, and a nut sleeve 35 is threadedly connected to the outer wall of the screw 34. A pin 36 is fixedly connected to one side of the nut sleeve 35, inserting into the mating hole 39 to fix the lower protrusion 32 to the base 38. The nut sleeve 35 is cuboid in shape and slidably connected to the inner wall of the base 38. The cuboid structure restricts the rotational freedom of the nut sleeve 35, allowing it to move only in a straight line along the inner wall of the base 38. A hexagonal socket 37 is provided at one end of the screw 34, allowing a hexagonal wrench to be inserted into it, enabling the operator to easily rotate the screw 34.

[0021] Reference Figures 1 to 7In one aspect of this embodiment, the protective assembly 2 includes a permanent magnet motor body 21, the output shaft of which passes through the mounting plate 1 to transmit power to external equipment. Positioning rods 22 are fixedly connected to one side of the mounting plate 1; four positioning rods 22 are located at the four corners of the mounting plate 1. The protective assembly 2 also includes a protective shell 23, which is cylindrical in shape. The positioning rods 22 can be inserted into the side wall of the protective shell 23 to achieve precise positioning and installation of the protective shell 23. Four fitting pieces 25 are fixedly connected to the outer wall of one end of the protective shell 23, distributed along the protective shell 23. The protective assembly 2 also includes bolts 26, which are threadedly connected to the fitting pieces 25 and the mounting plate 1, securely fixing the protective shell 23 to the mounting plate 1. An arc-shaped stabilizing block 27 is fixedly connected to the inner wall of the protective shell 23. A shock-absorbing sponge pad is fixedly connected to the inner wall of the arc-shaped stabilizing block 27 and contacts the outer wall of the permanent magnet motor body 21. The shock-absorbing sponge pad is made of a material with good elasticity and excellent shock absorption effect, effectively buffering the vibration generated by the permanent magnet motor body 21 during operation. A heat dissipation dust cover 24 is threadedly connected to the inner wall of one end of the protective shell 23. The heat dissipation dust cover 24 is made of a material with good air permeability and dustproof function. Its outer wall has anti-slip textures 28, which increase the friction between the hand and the heat dissipation dust cover 24, facilitating installation and disassembly by operators. This solution includes the following working process: Working Principle: During installation of this multi-cavity, low-resistance, external rotor permanent magnet motor, the base 38 is first fixed in the preset installation position. Then, the lower protrusion 32 on the bottom of the support plate 31 is aligned with and inserted into the interior of the base 38, completing the initial positioning of the motor. Next, a hex wrench is inserted into the hexagonal socket 37 at one end of the screw 34, and rotating the hex wrench causes the screw 34 to rotate. Because the nut sleeve 35 is rectangular and slidably connected to the inner wall of the base 38, when the screw 34 rotates, the nut sleeve 35 does not rotate with the screw 34, but moves linearly along the inner wall of the base 38. Simultaneously, the movement of the nut sleeve 35 causes the pin 36 to move synchronously. When the pin 36 is inserted into the mating socket 39 on the lower protrusion 32, the rotation of the hex wrench is stopped. At this point, the lower protrusion 32 is firmly fixed inside the base 38, completing the overall installation of the motor. In terms of protection, the protective shell 23 provides all-around protection for the permanent magnet motor body 21, effectively blocking impacts from external objects and preventing damage to the permanent magnet motor body 21. Vibrations generated during operation of the permanent magnet motor body 21 are absorbed by the shock-absorbing sponge pads on the inner wall of the arc-shaped stabilizing block 27, reducing the impact of vibrations on the internal components of the permanent magnet motor body 21 and ensuring the stability of motor operation. Simultaneously, the heat dissipation and dustproof cover 24 at one end of the protective shell 23 can dissipate the heat generated by the permanent magnet motor body 21 during operation to the outside in a timely manner, preventing the internal temperature of the motor from becoming too high; it also prevents external dust and other debris from entering the motor, avoiding wear or malfunction of components due to dust accumulation. When disassembly and maintenance of the motor are required, simply rotate the screw 34 in the reverse direction, causing the nut sleeve 35 and the pin post 36 to move away from the mating hole 39. Once the pin post 36 is completely disengaged from the mating hole 39, the lower protrusion 32 can be removed from inside the base 38, completing the disassembly of the motor. In addition, when it is necessary to clean the heat dissipation dust cover 24, the operator can use the anti-slip texture 28 on the outer wall of the heat dissipation dust cover 24 to rotate the heat dissipation dust cover 24 to remove it from the protective shell 23. After cleaning, it can be installed back in its original position.

[0022] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
