Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to a generator. Background Art

[0002] The principle of the generator is that the conductor cuts the magnetic flux lines to generate induced current. The stator of the traditional generator is a wire winding coil. The defects of this design are:

[0003] The larger the size, the heavier the weight, and the wire winding coils require a lot of copper wires and other metal wires, making the generator expensive. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a generator, which greatly reduces the volume and weight of the generator by adopting a circuit board stator as a stator, and the double stator design ensures the power generation efficiency.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] The present invention provides a generator, comprising a mounting shell, wherein a first stator and a second stator are arranged opposite to each other in the mounting shell, wherein the first stator and the second stator are both circuit board stators, wherein a through hole is opened in the middle of the first stator and the second stator, and a rotating shaft is passed through the through hole, wherein the rotating shaft is rotatably connected to the mounting shell, and the rotating shaft extends out of the mounting shell;

[0007] A rotor disk is fixedly sleeved on the rotating shaft, and the rotor disk is arranged between the first stator and the second stator.

[0008] In the generator of the present invention, the first stator and the second stator are both circuit board stators. The circuit board stator is a stator with windings arranged on a circuit board to form coils. The first stator and the second stator serve as conductors. The magnetic ring on the rotor disk carries a magnetic field. When the rotating shaft is driven to rotate by an external force to drive the rotor disk to rotate, the magnetic ring rotates, that is, the magnetic field moves, while the first stator and the second stator are fixed, which is equivalent to the wires on the first stator and the second stator cutting the magnetic flux lines of the magnetic field generated by the magnetic ring. Therefore, an induced current is generated in the wires on the first stator and the second stator, thereby generating electricity.

[0009] The generator of the present invention adopts a circuit board stator as a stator, thereby greatly reducing the volume and weight of the generator, and the double-stator design ensures the power generation efficiency.

[0010] In a further technical solution, first mounting holes are correspondingly formed on the mounting housing, the first stator and the second stator, and the first mounting holes are used to mount the first stator and the second stator.

[0011] The first stator and the second stator are installed from the inside of the installation shell through the first installation hole, and the structure is compact and the installation stability is good.

[0012] In a further technical solution, the first stator and the second stator are electrically connected via a first connector.

[0013] The wires on the first stator and the second stator need to be connected to the outside to form a power generation circuit. When the first stator and the second stator are connected through the first connector, the circuit can be formed by connecting only one side, which makes the wiring simpler.

[0014] In a further technical solution, a second connector is provided on the mounting shell, and one of the first stator and the second stator is electrically connected to the second connector.

[0015] The second connector can be used to conveniently connect and disconnect the wires, and the wiring is safer.

[0016] In a further technical solution, annular mounting grooves are respectively provided on the two annular surfaces of the rotor disk, and magnetic rings are installed in the annular mounting grooves.

[0017] The design of the magnetic ring enables the rotor disk to have a more stable magnetic field, and it is easy to install and has high stability.

[0018] In a further technical solution, the installation shell includes a first installation shell and a second installation shell that are arranged opposite to each other.

[0019] The first installation shell and the second installation shell are buckled together to form the installation shell, which is convenient for processing and manufacturing as well as for assembling the internal components.

[0020] In a further technical solution, second mounting holes are respectively opened on the first mounting shell and the second mounting shell, and the second mounting holes are used to connect the first mounting shell and the second mounting shell.

[0021] By providing the second mounting hole, the first mounting shell and the second mounting shell can be conveniently fixed together, and the second mounting hole can also be used as a mounting hole position for the entire mounting shell, so that it is convenient to install it at the power generation position.

[0022] In a further technical solution, a plurality of stators and rotor disks are sequentially arranged in the installation shell, and the stators and rotor disks are arranged alternately.

[0023] Multiple stator and rotor discs arranged in an interlaced manner can greatly increase the power of the generator and are suitable for scenarios with higher power generation intensity.

[0024] The beneficial effects are:

[0025] 1. The generator of the present invention uses a circuit board stator as a stator, which greatly reduces the volume and weight of the generator, and the double stator design ensures the power generation efficiency.

[0026] 2. The first stator and the second stator are installed from the inside of the installation shell through the first installation hole, with a compact structure and good installation stability.

[0027] 3. The wires on the first stator and the second stator need to be connected to the outside to form a power generation circuit. The first stator and the second stator are connected through the first connector, and the circuit can be formed by connecting only one side, which makes the wiring simpler.

[0028] 4. Wiring and disconnecting can be easily done through the second connector, and the wiring is safer.

[0029] 5. The design of the magnetic ring makes the rotor disk have a more stable magnetic field, and it is easy to install and has high stability.

[0030] 6. The first installation shell and the second installation shell are fastened together to form the installation shell, which is convenient for processing and manufacturing as well as for assembling its internal components.

[0031] 7. By setting the second mounting hole, the first mounting shell and the second mounting shell can be conveniently fixed together, and it can also be used as the mounting hole position of the entire mounting shell, so that it is convenient to install it at the power generation position.

[0038] Example:

[0040] A rotor disk 50 is fixedly sleeved on the rotating shaft 60 , and the rotor disk 50 is arranged between the first stator 30 and the second stator 40 .

[0041] In the generator of the present invention, the first stator 30 and the second stator 40 are both circuit board stators. The circuit board stator is a stator in which windings are arranged on a circuit board to form coils. The first stator 30 and the second stator 40 serve as conductors. The magnetic ring 51 on the rotor disk 50 has a magnetic field. When the rotating shaft 60 is driven to rotate by an external force to drive the rotor disk 50 to rotate, the magnetic ring 51 rotates, that is, the magnetic field moves, while the first stator 30 and the second stator 40 are fixed, which is equivalent to the wires on the first stator 30 and the second stator 40 cutting the magnetic flux lines of the magnetic field generated by the magnetic ring 51. Therefore, an induced current is generated in the wires on the first stator 30 and the second stator 40, thereby generating electricity.

In this embodiment, the original wiring holes on the circuit board stator are directly connected to the first connector 13, so that the circuits on the two circuit board stators are connected.

[0050] The wires on the first stator 30 and the second stator 40 need to be connected to the outside to form a power generation circuit. The first stator 30 and the second stator 40 are connected together through the first connector 13, and the circuit can be formed by connecting only one side, which makes the wiring simpler.

[0051] In another embodiment, if Figure 2 As shown, a second connector 14 is provided on the mounting housing, and one of the first stator 30 and the second stator 40 is electrically connected to the second connector 14 .

[0053] Continuing from the previous embodiment, one end of the second connector 14 passes through the housing and reaches the wiring hole on the second stator 40, so that the second connector 14 is in full contact with the second stator 40, thereby ensuring the stability of electrical conduction.

[0057] The first installation shell 10 and the second installation shell 20 are buckled together to form the installation shell, which is convenient for processing and manufacturing, and also convenient for assembly of its internal components.

[0058] In another embodiment, if Figure 1 and Figure 3As shown, the first mounting shell 10 and the second mounting shell 20 are respectively provided with second mounting holes 12 , and the second mounting holes 12 are used to connect the first mounting shell 10 and the second mounting shell 20 .

[0060] In another embodiment, a plurality of stator and rotor disks are sequentially arranged in the mounting shell, and the stator and rotor disks are arranged alternately.
