Background

At present, the performance of more and more electronic devices is continuously optimized, and some electronic devices are already configured with functional modules capable of rotating, thereby realizing more flexible work. Taking a functional module as a camera as an example, the current electronic equipment is provided with a rotatable camera, and in a specific working process, the rotation of the camera can realize the adjustment of a shooting visual angle.

Obviously, this results in a larger diameter of the motor, and the application of the motor with such a structure to the electronic device results in a larger thickness of the electronic device, which is not favorable for designing the electronic device toward a thinner direction.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 3, an embodiment of the invention discloses a motor, which can be applied to electronic devices. The motor disclosed in the embodiment of the present invention includes a stator 100 and a magnetic rotor 200.

The stator 100 is fixedly disposed, and the stator 100 includes at least two winding coils. During operation of the electric machine, the at least two winding coils are energized, thereby forming an electromagnetic field.

The magnetic rotor 200 is rotatably coupled to the stator 100 so as to be rotatable with respect to the stator 100. In the embodiment of the present invention, the at least two winding coils are sequentially distributed in the direction of the rotation axis of the magnetic rotor 200. Under the condition that the at least two winding coils are energized, the magnetic rotor 200 is driven by a magnetic field force in an electromagnetic field, the magnetic rotor 200 rotates around the stator 100 in a preset direction, and finally, the electric energy is converted into the mechanical energy of the magnetic rotor 200.

Because the at least two winding coils are sequentially distributed along the rotation axis direction of the magnetic rotor 200, the formed electromagnetic field can continuously superpose driving forces in the axis direction of the magnetic rotor 200, thereby realizing the driving of the rotation of the magnetic rotor 200.

The motor disclosed in the embodiment of the present invention improves the structure of the motor in the prior art, and sequentially distributes at least two winding coils included in the stator 100 in the rotation axis direction of the magnetic rotor 200, so as to form an electromagnetic field superimposed in the rotation axis direction of the magnetic rotor 200, and further, each part of the magnetic rotor 200 in the axis direction thereof can be driven, thereby ensuring the electromagnetic driving capability. Because the at least two winding coils are overlapped in the direction of the rotation axis of the magnetic rotor 200, more winding coils are not required to be arranged in the circumferential direction of the magnetic rotor 200 under the condition of ensuring the same electromagnetic drive, the problem that the radial size of the motor is larger because more winding coils are arranged in the circumferential direction can be avoided, the influence on the thickness size of the electronic equipment can be finally relieved, and the development of the electronic equipment towards a thinner direction is facilitated.

In the embodiment of the present invention, the structure of the at least two winding coils may be various. In an optional scheme, the at least two winding coils include at least two first sub-coils, the at least two first sub-coils are disposed on a first side of the magnetic rotor 200 and sequentially distributed along a rotation axis direction of the magnetic rotor 200, and the magnetic rotor 200 rotates around the stator 100 in a preset direction when the at least two first sub-coils are in an energized state. In this case, the electromagnetic field formed by the at least two first sub-coils in the energized state can drive the magnetic rotor 200 to rotate.

In a further technical solution, the at least two winding coils include at least two second sub-coils on the basis of including at least two first sub-coils, the at least two second sub-coils are disposed on a second side of the magnetic rotor 200 and are sequentially distributed along a rotation axis direction of the magnetic rotor 200, when the at least two second sub-coils are in an energized state, the magnetic rotor 200 rotates around the stator 100 in the preset direction, and the first side and the second side may be two adjacent sides of the magnetic rotor 200, in this case, the at least two first sub-coils and the at least two second sub-coils cooperate to provide a stronger electromagnetic field to the magnetic rotor 200, so that a driving capability of the magnetic rotor 200 can be improved, and finally, the output power of the motor can be stronger.

In another alternative, the first side and the second side are opposite sides of the magnetic rotor 200. In this case, the at least two first sub-coils and the at least two second sub-coils are respectively disposed on opposite sides of the magnetic rotor 200, so that a relatively uniform electromagnetic field can be provided, and the rotational stability of the magnetic rotor 200 can be further improved.

In order to improve the smoothness of the rotational drive of the magnetic rotor 200, the at least two winding coils 110 may be distributed in groups. The plurality of sets of winding coils 110 are sequentially distributed along the rotation axis direction. The number of winding coils 110 in each set is at least two. The windings of the winding coils 110 in the same group are not all the same, so that smooth driving can be achieved, and the magnetic rotor 200 can receive a more uniform driving force as much as possible when rotated to various positions. In a specific embodiment, the number of the winding coils 110 in each group may be two, and the winding directions of the winding coils 110 in the same group are opposite, so that the electromagnetic field can be better continued in terms of driving, and the driving of the rotation of the magnetic rotor 200 is more facilitated. As shown in fig. 1, the winding coil 1 and the winding coil 2 form a set, and the winding directions of the winding coil 1 and the winding coil 2 are opposite. The winding coil 3 and the winding coil 4 form a group, and the winding directions of the winding coil 3 and the winding coil 4 are opposite. The winding coil 5 and the winding coil 6 form a group, and the winding directions of the winding coil 5 and the winding coil 6 are opposite.

Referring to fig. 1, in an alternative scheme, in the extending direction of the rotation axis of the magnetic rotor 200, any adjacent three groups of winding coils 110 are respectively connected with the W wire, the V wire and the W wire of the three-phase power, so as to realize the access of the alternating power supply. The mode of distributing the wiring facilitates the assembly operation and the subsequent maintenance of operators.

In the embodiment of the present invention, the magnetic structure of the magnetic rotor 200 may be various as long as it is ensured that the magnetic rotor 200 rotates within the electromagnetic field formed by the stator 100. Referring to fig. 1 to 3 again, in an alternative scheme, the magnetic rotor 200 may include magnetizing regions 210 sequentially arranged along a rotation axis direction, each magnetizing region 210 is disposed opposite to one set of winding coils 110, the magnetizing region 210 includes at least two magnetizing sections 211 sequentially arranged along an extending direction of the rotation axis, the number of the magnetizing regions 210 is equal to that of the winding coils 110, each magnetizing region 210 may be disposed opposite to one winding coil 110, the magnetizing section 211 includes at least two magnetizing sub-regions 211a distributed along a circumferential direction of the magnetic rotor 200, and in the same magnetizing section 211, two adjacent magnetizing sub-regions 211a have opposite magnetism. In this case, each of the magnetizing regions 210 of the magnetic rotor 200 is disposed opposite to one of the winding coils 110, so that a magnetic driving is formed therebetween. The magnetizing regions 210 are sequentially arranged along the axial direction of the magnetic rotor 200, so that the driving in the rotational axial direction of the magnetic rotor 200 can be superimposed, and the electromagnetic driving force can be improved.

Meanwhile, at least two magnetizing sub-regions 211a included in the magnetizing section 211 are distributed along the circumferential direction of the magnetic rotor 200, and in the same magnetizing section 211, the two adjacent magnetizing sub-regions 211a have opposite magnetism, so that stable electromagnetic driving can be further ensured.

In a further technical scheme, in any two adjacent magnetizing regions 210, magnetizing sub-regions 211a with the same magnetism in two adjacent magnetizing sections 211 are distributed in a staggered manner according to a preset angle in the circumferential direction of the magnetic rotor 200, and the preset angle is smaller than a central angle corresponding to the magnetizing sub-region 211 a. In this case, in any two adjacent magnetizing regions 210, the magnetizing sub-regions 211a with the same magnetism in the adjacent magnetizing sections 211 have a dislocation of a preset angle, so that the driving continuity can be further improved, and the rotation of the magnetic rotor 200 is more stable.

For convenience of design and full utilization of the space in the axial direction of the magnetic rotor 200, in each magnetizing section 211, any two magnetizing subregions 211a have the same size, so that the stress of the magnetic rotor 200 in the continuous driving process can be more balanced, and the improvement of the rotation stability of the magnetic rotor 200 is facilitated.

In the motor disclosed in the embodiment of the present invention, the stator 100 may further include a bracket 120, as shown in fig. 1 and fig. 2, the bracket 120 may be rotatably engaged with the magnetic rotor 200, the at least two winding coils 110 are disposed on the bracket 120, and the bracket 120 may provide an installation basis for the winding coils 110, so as to facilitate forming an integral module with the winding coils 110 for assembly. Alternatively, the bracket 120 may have a through hole, and the magnetic rotor 200 may be disposed in the through hole, in which case the magnetic rotor 200 can be in the through hole, so that the protection of the stator 100 can be obtained.

In order to improve the electromagnetic driving performance, in a further embodiment, the stator 100 may further include at least two magnetic conductive blocks 130, and each magnetic conductive block 130 is disposed opposite to one winding coil. Two adjacent magnetic conduction blocks 130 are arranged at intervals. The magnetic conductive blocks 130 can better guide the magnetic field distribution, thereby making the electromagnetic field more favorable for driving the magnetic rotor 200.

Referring to fig. 2 again, the magnetic rotor 200 is disposed in the through hole of the bracket 120, the surface of the magnetic conducting block 130 facing the magnetic rotor 200 may be an arc surface, and the arc surface is adapted to the region of the outer surface of the magnetic rotor 200, so that the magnetic conducting block 130 and the magnetic rotor 200 can be assembled compactly, which is beneficial to further reducing the size of the motor.

In the embodiment of the present invention, the magnetic rotor 200 and the bracket 120 may be rotatably connected by a bearing 300, but may also be assembled by other assembling methods capable of realizing rotation.

In a general case, the magnetic rotor 200 may be a cylindrical structural member. In an alternative, the magnetic rotor 200 may be a cylindrical structure, and the cylindrical structure is a hollow structure, in which case, the hollow structure of the magnetic rotor 200 may also allow cables to pass through or install sensors and the like therein. It is apparent that the magnetic rotor 200 of such a structure facilitates more compact assembly of the electronic apparatus.

Based on the motor disclosed by the embodiment of the invention, the embodiment of the invention discloses electronic equipment, the disclosed electronic equipment comprises a shell, a functional module and the motor disclosed by the embodiment, the motor is arranged on the shell, the functional module is in driving connection with the magnetic rotor 200, and the magnetic rotor drives the functional module to move, so that the change of the position of the functional module is realized.

In the embodiment of the present invention, the functional module may include a camera, a fill-in light, a receiver, a fingerprint recognition module, a USB interface, and the like.

The motor can finally make magnetism rotor 200 rotate at the in-process of work, and magnetism rotor 200 can directly link to each other with the function module to the driving function module rotates, and of course, magnetism rotor 200 can also realize linking to each other with the function module through drive mechanism, and then realizes the drive to the function module. In the embodiment of the present invention, the magnetic rotor 200 can drive the functional module to rotate and also can drive the functional module to move.

The electronic device disclosed in the embodiment of the present invention may be a mobile phone, a tablet computer, an electronic book reader, a game machine, a wearable device, or the like, or may be other devices.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
