Description

Technical Field

[0001] The invention relates to the technical field of axial magnetic field motors, in particular to a small axial magnetic flux oscillation motor. Background Art

[0002] An oscillation motor, also known as a vibration motor, is a type of motor. A micro vibration motor is a commonly used small motor that is often used in electronic equipment. With the continuous development of modern technology, the use of vibration motors is becoming more and more common, and its scope of use is becoming more and more extensive, including mobile phones, tablets, watches, game consoles, cars, etc.

[0003] The function of the vibration motor in the mobile phone is: when a text message or a call is received, the motor starts, driving the eccentric wheel to rotate at high speed, thereby generating vibration. The trends of vibration motors in mobile phones include small size, light weight, low energy consumption, and ensuring reliable vibration and alarm in any situation.

[0004] Traditional micro vibration motors are usually radial magnetic field motors, with a set of adjustable eccentric blocks installed at both ends of the motor's shaft. The centrifugal force generated by the high-speed rotation of the shaft and the eccentric blocks is used to obtain the exciting force, thereby generating vibration. Therefore, the motor is cylindrical, has a complex structure, and is large in size. The existing axial magnetic field motor has a compact structure, a small size, a disc shape, and a flat structure. It can be made into a button-type vibration motor, but the button-type vibration motor will generate heat inside when it is in use, and the motor conducts and dissipates the heat through the outer casing. At the same time, the motor is fixed to the circuit board of the mobile phone by soldering. Therefore, when the motor fails and cannot be used, the motor cannot be easily replaced. In order to further improve the heat dissipation efficiency of the motor and when the motor fails and cannot be used, the motor cannot be easily replaced. Based on this, a small axial flux oscillation motor is now provided to eliminate the disadvantages of the existing device. Summary of the invention

The two elastic pressing plates 305 are in contact with the outer walls of the fixed bottom plate 4 and the fixed cylinder 102. The fixed bottom plate 4 and the fixed cylinder 102 are connected to the two elastic pressing plates 305 by sliding up and down. The fixed bottom plate 4 and the fixed cylinder 102 can be clamped and positioned by the two elastic pressing plates 305 to avoid the fixed bottom plate 4 and the fixed cylinder 102 from being offset.

[0067] A conductive component is disposed on the connecting bottom plate 306 , and the conductive component is used to supply power to the first coil 203 and the second coil 206 .

[0068] In one embodiment, Figure 6-Figure 7 As shown, the conductive components include:

[0069] Two first conductive sheets 3010 are symmetrically fixedly connected to the top of the connecting base plate 306, and the bottom ends of the two first conductive sheets 3010 are fixedly connected with power supply pins penetrating to the outside of the bottom end of the connecting base plate 306.

[0070] A limiting assembly is provided on the fixed cylinder 102, and the limiting assembly is used to limit the movement of the single-stator single-rotor axial magnetic field motor 1;

[0071] In one embodiment, Figure 3-Figure 6 As shown, the limit assembly includes:

[0072] A positioning plug 301 is fixedly connected to the outer wall of the fixed cylinder 102. The outer wall of the bottom end of the positioning plug 301 is in an inclined shape. The positioning plug 301 penetrates into an elastic pressure plate 305. A guide groove 304 for the positioning plug 301 to slide up and down is provided at the position where the elastic pressure plate 305 and the positioning plug 301 meet. The positioning plug 301 and the guide groove 304 cooperate with each other to limit the installation of the fixed cylinder 102, so as to prevent the fixed cylinder 102 from rotating when in use.

[0073] A heat dissipation component is disposed on an elastic pressure plate 305, and the heat dissipation component is used to improve the heat dissipation efficiency of the single-stator single-rotor axial magnetic field motor 1, and to squeeze and limit the single-stator single-rotor axial magnetic field motor 1;

[0074] In one embodiment, Figure 1-Figure 6As shown, the heat dissipation component includes:

[0075] A first heat conducting plate 303 is rotatably connected to the top of an elastic pressure plate 305 via a rotating shaft, a plurality of heat sinks 302 are vertically and equidistantly formed on one side of the first heat conducting plate 303, a second heat conducting plate 3011 is fixedly connected to the inner wall of the fixed cylinder 102, and the second heat conducting plate 3011 is located above the magnetic yoke 209. The first heat conducting plate 303, the second heat conducting plate 3011 and the plurality of heat sinks 302 cooperate with each other to effectively improve the heat dissipation efficiency of the fixed cylinder 102;

[0076] A clamping assembly is provided on the side of the other elastic pressure plate 305 away from the single-stator single-rotor axial magnetic field motor 1, and the clamping assembly is used to clamp and fix the first heat conducting plate 303;

[0077] In one embodiment, Figure 1-Figure 6 As shown, the snap-fit ​​assembly includes:

[0078] A fixed block 309 is fixedly connected to another elastic pressure plate 305 on a side away from the single-stator single-rotor axial magnetic field motor 1. The top of the fixed block 309 is fixedly connected to an elastic push plate 308. A positioning block 307 is integrally formed at the top of the elastic push plate 308. The upper surface of the positioning block 307 close to the side of the single-stator single-rotor axial magnetic field motor 1 is inclined. Through the mutual cooperation between the positioning block 307 and the elastic push plate 308, the positioning block 307 can be engaged and fixed to the first heat conducting plate 303.

[0079] The above embodiment discloses a small axial flux oscillation motor, wherein it is particularly noted that: the first coil 203 and the second coil 206 located inside the single-stator single-rotor axial magnetic field motor 1 can be provided in multiple groups according to the use requirements;

[0080] During installation, the single-stator single-rotor axial magnetic field motor 1 is pushed so that the fixed base plate 4 moves to the top of the connecting base plate 306, and then the inner wall of an elastic pressure plate 305 is squeezed by the fixed cylinder 102, so that an elastic pressure plate 305 can be offset through slight deformation, and then the fixed cylinder 102 is pushed down along the inner wall of an elastic pressure plate 305. At this time, the positioning plug 301 is inserted into the inside of the guide groove 304 under the drive of the fixed cylinder 102, until the fixed base plate 4 is pushed by the fixed cylinder 102 to contact the upper surface of the connecting base plate 306, and then the fixed cylinder 102 is released. At this time, one elastic pressure plate 305 elastically pushes the fixed cylinder 102 to contact the inner wall of the other elastic pressure plate 305, so that the fixed cylinder 102 can be clamped and limited by the two elastic pressure plates 305;

[0081] During this process, the fixed bottom plate 4 can push the two second conductive sheets 3012 to contact the upper surfaces of the two first conductive sheets 3010 respectively by moving, so as to realize the subsequent power supply operation to the first coil 203 and the second coil 206;

[0082] Then, heat dissipation silicone is evenly applied on the upper surface of the second heat conducting plate 3011, and then the first heat conducting plate 303 is pulled to flip around the rotating shaft until the first heat conducting plate 303 contacts the heat dissipation silicone on the upper surface of the second heat conducting plate 3011. During this process, the positioning block 307 pushes the elastic push plate 308 to deform under the pressure of the first heat conducting plate 303 through the inclined outer wall. When the first heat conducting plate 303 contacts the heat dissipation silicone, the elastic push plate 308 drives the positioning block 307 to reset through rebound, and the positioning block 307 contacts the upper surface of the first heat conducting plate 303 through movement, so that the first heat conducting plate 303 can be fixed by clamping;

[0083] When in use, the two first conductive sheets 3010 can be powered respectively through the power supply pins, and then the two first conductive sheets 3010 can be powered respectively to the first coil 203 and the second coil 206 through the two second conductive sheets 3012;

[0084] At this point, it is necessary to explain in particular that the stator is composed of a fixed chassis 101, a fixed bottom plate 4, a first limiting plate 201, a first coil 203, a second limiting plate 205, a second coil 206 and a stop core 204, and the rotor is composed of a bearing 202, a magnetic pole 208 and a magnetic yoke 209. There is a certain air gap between the stator and the rotor, which can move relative to each other. When the stator is energized, a rotating magnetic field is generated. This magnetic field rotates at a synchronous speed in the air gap between the stator and the rotor. Due to the asymmetric size of the first coil 203 and the second coil 206, the stator rotating magnetic field will be asymmetric, which will cause the rotor to vibrate during the rotation process, so that the oscillation operation can be performed without the eccentric wheel.

[0085] When the interior of the fixed cylinder 102 generates heat due to the rotation of the magnetic pole 208, the heat in the inner cavity of the fixed cylinder 102 can be transferred to the first heat conducting plate 303 through the second heat conducting plate 3011, and then the first heat conducting plate 303 can transfer the heat to the air through the plurality of heat sinks 302. In this process, the heat dissipation silica gel can further improve the efficiency of heat transfer from the second heat conducting plate 3011 to the first heat conducting plate 303, and the heat dissipation efficiency of the heat in the inner cavity of the fixed cylinder 102 can be further improved.

[0086] When the single-stator single-rotor axial magnetic field motor 1 fails to work, the above operation can be reversed by pulling the positioning block 307, so as to achieve the purpose of convenient replacement of the single-stator single-rotor axial magnetic field motor 1.

[0087] The above is only a specific implementation of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
