With the rapid development of power electronics technology and new semiconductor devices, AC speed regulation technology has been continuously improved and enhanced. The gradually improved frequency converters have been widely used in AC motors with their good output waveform and excellent performance-price ratio, and have achieved good results.

[0003] The utility model with publication number CN212137485U relates to a variable frequency motor, including a networking module, a single-chip microcomputer, a frequency converter, a variable frequency motor body, a temperature sensor, a vibration sensor, a speed acquisition mechanism and a remote control terminal. The networking module and the frequency converter are connected to the single-chip microcomputer through a serial port, the temperature sensor and the vibration sensor are connected to the IO pin of the single-chip microcomputer, the frequency converter is connected to the variable frequency motor body, and the single-chip microcomputer is communicatively connected to the remote control terminal through the networking module; the probes of the temperature sensor and the vibration sensor are abutted against the outer shell of the variable frequency motor body.

[0004] The variable frequency motor in the above technical solution cannot adjust the angle between the motor output shaft and the bottom mounting surface of the motor during installation, so that in actual use of the motor, in order to cooperate with various equipment, the output angle of the motor needs to be adjusted through an additional angle adjustment device, making the installation process of the motor cumbersome and inefficient. Utility Model Content

[0005] In order to make the motor adaptable to the installation of different equipment, the present application provides a variable frequency motor.

[0006] The variable frequency motor provided in this application adopts the following technical solution:

[0007] A variable frequency motor comprises a motor body, a mounting seat and an angle adjustment assembly, wherein the adjustment assembly is used to adjust the angle between the output shaft of the motor body and the mounting surface of the mounting seat, and the adjustment assembly comprises a rotating seat, a rotating plate, a driving member and a limiting assembly, wherein the rotating seat is arranged on the motor body, one end of the rotating plate is rotatably connected to the rotating seat, and the other end of the rotating plate is rotatably connected to the mounting seat along a rotating axis perpendicular to the rotating seat, the driving member is used to drive the rotation of the rotating seat, and the limiting assembly is used to limit the rotation of the rotating plate.

[0008] By adopting the above technical solution, the angle between the bottom surface of the motor body and the bottom surface of the mounting seat is adjusted by the rotating plate, and the rotating seat is driven to rotate by the driving member to adjust the direction of the output shaft of the motor body, thereby adjusting the output angle of the motor, so that the motor can adapt to more equipment.

[0009] Preferably, the driving member includes a turbine, a worm and a limit member, the turbine is coaxially and fixedly connected to the rotating seat, the worm is rotatably connected to the rotating plate along a rotation direction perpendicular to the rotating seat, the turbine is meshingly connected to the worm, and the limit member is used to limit the rotation of the worm.

[0010] By adopting the above technical solution, the worm is rotated, and the turbine is rotated through the meshing connection between the worm and the turbine, thereby rotating the rotating seat, and the lead angle of the worm is smaller than the equivalent friction angle between the meshing gear teeth. The turbine and worm are self-locking, and reverse self-locking can be achieved, that is, the worm can only drive the worm wheel, but not the worm wheel, that is, when the motor vibrates, the turbine cannot drive the worm to move, reducing the possibility of the angle between the motor and the mounting seat being offset during use.

[0011] Preferably, the limiting member includes a force rod, one end of which is coaxially and slidably connected to the worm, a force block is provided at the end of the force rod away from the worm, the axial cross-sections of the force rod and the force block are both polygonal, and a limiting hole that can cooperate with the force block is provided on the rotating plate. When the force block slides toward one side of the worm to the extreme position, the force block cooperates with the limiting hole.

[0012] By adopting the above technical solution, when the force block is pushed to slide toward one side of the worm until the force block cooperates with the limiting hole, the rotation of the worm is limited, reducing the possibility of the worm rotating due to the vibration during the movement of the motor; when the force block is pulled to slide toward the side away from the worm until the force block is out of the limiting hole, the limit on the rotation of the worm is released, and the force block is rotated at this time to cause the force rod to drive the worm to rotate together.

[0013] Preferably, a first rubber sleeve is provided on the circumferential side surface of the force applying block.

[0014] By adopting the above technical solution and setting the first rubber sleeve, when the force block cooperates with the limiting hole, the first rubber sleeve abuts against the inner wall of the limiting hole, thereby increasing the friction between the force block and the limiting hole and reducing the possibility of the force block detaching from the limiting hole when the motor vibrates. The rubber sleeve can also play a shock-absorbing role and reduce the possibility of wear between the force block and the limiting hole due to motor vibration.

[0015] Preferably, the limit assembly includes a spline, which passes through a mounting seat along the rotation direction of the rotating plate and is slidably connected to the rotating plate. The mounting seat is provided with a first keyway that can cooperate with the spline, and the rotating plate is provided with a second keyway that can cooperate with the spline. When the spline slides toward one side of the rotating plate to the extreme position, the spline cooperates with the first keyway and the second keyway at the same time.

[0016] By adopting the above technical solution, when the spline cooperates with the first keyway and the second keyway at the same time, the rotation between the rotating plate and the mounting seat is limited; when the spline slides to disengage from the second keyway, the rotating plate can be rotated on the mounting seat to adjust the angle between the rotating plate and the mounting seat.

[0017] Preferably, the limiting assembly also includes a support plate, a plurality of first slots are provided on the rotating plate, and the plurality of first slots are evenly distributed on the rotating plate along a direction perpendicular to the rotating axis of the rotating plate, a plurality of second slots are provided on the mounting seat, and the plurality of second slots are evenly distributed on the mounting seat along a direction perpendicular to the rotating axis of the rotating plate, one end of the support plate can be plugged in and matched with any first slot, and the other end of the support plate can be plugged in and matched with any second slot.

[0018] By adopting the above technical solution, the two ends of the support plate are respectively plugged into the first slot and the second slot, so that the support plate supports the rotating plate, thereby reducing the possibility of angle deviation between the rotating plate and the mounting seat caused by motor vibration during motor movement.

[0019] Preferably, both ends of the support plate are respectively sleeved with a second rubber sleeve.

[0020] By adopting the above technical solution, the second rubber sleeves are respectively provided at both ends of the support plate. When the two ends of the support plate are respectively matched with the first slot and the second slot, the friction between the first slot and the second slot is increased, thereby reducing the possibility of the support plate being separated from the first slot and the second slot due to motor vibration.

[0021] The technical effects of this utility model are mainly reflected in the following aspects:

[0022] 1. The utility model provides a rotating plate and a rotating seat, adjusts the angle between the bottom surface of the motor body and the bottom surface of the mounting seat by the rotating plate, and drives the rotating seat to rotate by the driving member to adjust the direction of the output shaft of the motor body, thereby adjusting the output angle of the motor, so that the motor can adapt to more equipment;

[0023] 2. The utility model sets a turbine and a worm, rotates the worm, and rotates the turbine through the meshing connection between the worm and the turbine, thereby rotating the rotating seat, and the lead angle of the worm is smaller than the equivalent friction angle between the meshing gear teeth. The turbine and the worm have self-locking properties, and reverse self-locking can be achieved, that is, the worm can only drive the worm wheel, but not the worm wheel. That is, when the motor vibrates, the turbine cannot drive the worm to move, reducing the possibility of the angle between the motor and the mounting seat being offset during use;

[0030] The following is combined with Figure 1-4 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0031] The embodiment of the present application discloses a variable frequency motor.

[0032] Reference Figure 1-Figure 4A variable frequency motor of this embodiment includes a motor body 1, a mounting seat 2 and an angle adjustment component 3. The adjustment component is used to adjust the angle between the output shaft of the motor body 1 and the mounting surface of the mounting seat 2. The adjustment component includes a rotating seat 31, a rotating plate 32, a driving member 33 and a limiting member 34. The rotating seat 31 is installed on the motor body 1. One end of the rotating plate 32 is rotatably connected to the rotating seat 31. The other end of the rotating plate 32 is rotatably connected to the mounting seat 2 along a rotation axis perpendicular to the rotating seat 31. The driving member 33 is used to drive the rotation of the rotating seat 31. The limiting member 34 is used to limit the rotation of the rotating plate 32. The angle between the bottom surface of the motor body 1 and the bottom surface of the mounting seat 2 is adjusted by the rotating plate 32, and the rotating seat 31 is driven to rotate by the driving member 33 to adjust the direction of the output shaft of the motor body 1, thereby adjusting the output angle of the motor, so that the motor can adapt to more equipment.

[0033] Reference Figure 1-Figure 4 The driving member 33 includes a turbine 331, a worm 332 and a stopper 333. The turbine 331 is coaxially and fixedly connected to the rotating seat 31. The worm 332 is connected to the rotating plate 32 in a direction perpendicular to the rotation direction of the rotating seat 31. The turbine 331 is meshed with the worm 332. The stopper 333 is used to limit the rotation of the worm 332. The worm 332 is rotated, and the turbine 331 is rotated through the meshing connection between the worm 332 and the turbine 331, so that the rotating seat 31 is rotated. The lead angle of the worm 332 is less than the equivalent friction angle between the meshing gear teeth. The turbine 331 and the worm 332 are self-locking, and reverse self-locking can be achieved, that is, the worm wheel can only be driven by the worm 332, and the worm wheel cannot drive the worm 332. That is, when the motor vibrates, the turbine 331 cannot drive the worm 332 to move, reducing the possibility of the angle between the motor and the mounting seat 2 being offset during use.

[0034] Reference Figure 1-Figure 4The limiting member 333 includes a force rod 3331, one end of the force rod 3331 is coaxially and slidably connected to the worm 332, and the end of the force rod 3331 away from the worm 332 is fixedly connected to a force block 3332. The axial cross-sections of the force rod 3331 and the force block 3332 are both polygonal. A limiting hole 321 that can cooperate with the force block 3332 is opened on the rotating plate 32. When the force block 3332 slides toward the side of the worm 332 to the limit position, the force block 3332 cooperates with the limiting hole 321. When the force block 3332 is pushed to slide toward the side of the worm 332 until the force block 3332 cooperates with the limiting hole 321, the rotation of the worm 332 is limited, reducing the possibility of the worm 332 rotating due to the vibration during the movement of the motor; when the force block 3332 is pulled to slide toward the side away from the worm 332 until the force block 3332 is disengaged from the limiting hole 321, the limit on the rotation of the worm 332 is released, and the force block 3332 is rotated at this time, so that the force rod 3331 drives the worm 332 to rotate together.

[0035] Reference Figure 1 and Figure 2 The first rubber sleeve 3333 is sleeved on the circumferential side of the force block 3332. By providing the first rubber sleeve 3333, when the force block 3332 is matched with the limiting hole 321, the first rubber sleeve 3333 abuts against the inner wall of the limiting hole 321, thereby increasing the friction between the force block 3332 and the limiting hole 321, and reducing the possibility that the force block 3332 is separated from the limiting hole 321 when the motor vibrates. In addition, the rubber sleeve can also play a role of shock absorption, thereby reducing the possibility of wear between the force block 3332 and the limiting hole 321 due to motor vibration.

[0036] Reference Figure 1-Figure 3 The limiting assembly 34 includes two splines 341. The two splines 341 penetrate the mounting seat 2 along the rotation direction of the rotating plate 32 and are slidably connected to the rotating plate 32. The mounting seat 2 is provided with two first keyways 21 that can cooperate with the splines 341. The rotating plate 32 is provided with two second keyways 323 that can cooperate with the splines 341. When the splines 341 slide to the limit position toward one side of the rotating plate 32, the two splines 341 are respectively and simultaneously cooperated with the two first keyways 21 and the two second keyways 323. When the splines 341 cooperate with the first keyways 21 and the second keyways 323 at the same time, the rotation between the rotating plate 32 and the mounting seat 2 is limited; when the splines 341 slide to disengage from the second keyways 323, the rotating plate 32 can be rotated on the mounting seat 2 to adjust the angle between the rotating plate 32 and the mounting seat 2.

[0037] Reference Figure 1 and Figure 2The limiting assembly 34 also includes a plurality of support plates 342. The rotating plate 32 is provided with a plurality of first slots 322, which are evenly distributed on the rotating plate 32 along a direction perpendicular to the rotation axis of the rotating plate 32. The mounting seat 2 is provided with a plurality of second slots 22, which are evenly distributed on the mounting seat 2 along a direction perpendicular to the rotation axis of the rotating plate 32. One end of the plurality of support plates 342 can be plugged and matched with any first slot 322, and the other end of the plurality of support plates 342 can be plugged and matched with any second slot 22. The two ends of the support plates 342 are plugged and matched with the first slot 322 and the second slot 22 respectively, so that the support plates 342 support the rotating plate 32, thereby reducing the possibility of the angle between the rotating plate 32 and the mounting seat 2 being deviated due to the vibration of the motor during the movement of the motor; by having a plurality of support plates 342, the mounting seat 2 and the rotating plate 32 can be supported by the plurality of support plates 342 at the same time, thereby increasing the stability of the motor during installation.

[0038] Reference Figure 1 and Figure 2 , the two ends of the support plate 342 are respectively sleeved with the second rubber sleeves 343. When the two ends of the support plate 342 are respectively sleeved with the second rubber sleeves 343, when the two ends of the support plate 342 are respectively matched with the first slot 322 and the second slot 22, the friction between the first slot 322 and the second slot 22 is increased, and the possibility of the support plate 342 being separated from the first slot 322 and the second slot 22 due to motor vibration is reduced.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
