[0003] The main objective of this invention is to provide a polarization motor that can adjust the amplitude in real time, in order to solve the problem that existing polarization motors cannot adjust the amplitude in real time.

[0004] The objective of this invention can be achieved by adopting the following technical solution: A spherical shell 1 is included, a motor 2 is installed inside the spherical shell 1, a rotating shaft 3 is installed at one end of the motor 2, a slidable slide rod is installed on the rotating shaft 3, an eccentric block 13 and a spring 12 are installed on the slide rod, an internally threaded column 4 is fixedly connected inside the spherical shell 1, an externally threaded column 5 is movably connected inside the internally threaded column 4, a rotating cap 7 is installed at one external end of the externally threaded column 5, and a limiting funnel 6 is installed at one internal end of the externally threaded column 5.

[0005] Preferably, the slidable slide rod includes a first slide rod 8, a limiting cap 9, a second slide rod 10, and a spring-loaded cap 11. The limiting cap 9 is fixed to one end of the first slide rod 8, the second slide rod 10 is slidably connected inside the first slide rod 8, and a spring-loaded cap 11 is provided at one end of the second slide rod 10.

[0013] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0014] like Figures 1-2 As shown, the polarization motor with real-time adjustable amplitude provided in this embodiment uses a centrifugal radius of the eccentric block 13 that can be adjusted in real time. By changing the centrifugal radius, the amplitude is changed. It includes a spherical shell 1, a motor 2 is installed inside the spherical shell 1, a rotating shaft 3 is installed at one end of the motor 2, a sliding rod is installed on the rotating shaft 3, and an eccentric block 13 and a spring 12 are installed on the sliding rod. An internally threaded column 4 is fixedly connected inside the spherical shell 1, and an externally threaded column 5 is movably connected inside the internally threaded column 4. A screwing point is provided at one end of the externally threaded column 5. The cap 7 and the inner end of the external threaded column 5 are provided with a limiting funnel 6; the sliding rod includes a first slide rod 8, a limiting cap 9, a second slide rod 10 and a spring-loaded cap 11. The limiting cap 9 is fixed to one end of the first slide rod 8, the second slide rod 10 is slidably connected inside the first slide rod 8, and a spring-loaded cap 11 is provided at one end of the second slide rod 10. An eccentric block 13 is fixedly connected to the spring-loaded cap 11; the eccentric block 13 is used in conjunction with the limiting funnel 6; the internal threaded column 4 and the external threaded column 5 are used in conjunction, and the internal threads are dense to increase friction.

[0015] In this embodiment, as Figure 1 As shown, the designed limiting funnel 6 is adjusted up and down according to the external thread column 5, thereby changing the contact position between the eccentric block 13 and the limiting funnel 6, thus changing the centrifugal radius of the eccentric block 13.

[0016] In this embodiment, as Figure 2As shown, the designed sliding rod can increase the adjustment range of the centrifugal radius, thereby making the amplitude range highly variable; the limiting cap 9 is fixed to one end of the first sliding rod 8, the second sliding rod 10 is slidably connected inside the first sliding rod 8, and a spring pressure cap 11 is provided at one end of the second sliding rod 10, and an eccentric block 13 is fixedly connected to the spring pressure cap 11.

[0017] In this embodiment, as Figures 1-2 As shown, the principle of the polarization motor with real-time adjustable amplitude provided in this embodiment is as follows: According to the amplitude formula, the amplitude is equal to the ratio of the eccentric mass to the eccentric radius to the overall mass. It is known that when the eccentric mass and the overall mass remain unchanged, the amplitude can be changed simply by changing the centrifugal radius. The radius of the adjustable eccentric block 13 designed in this invention can change the amplitude, thereby solving the problem that existing motors cannot solve the problem of real-time amplitude adjustment.

[0018] In summary, in this embodiment, a polarization motor with real-time adjustable amplitude is used.

[0019] The above description is merely a further embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
