A more flexible and faster electromagnetic motor is a design that is reasonable. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a component that can be reduced in size, reduced in relative volume, reduced in material, and thus reduced in cost and simple in assembly. Φ In order to achieve the above object, a cylinder type electromagnetic motor of the present invention comprises a base having a central hole; a resilient piece; a cover having a coupling assembly coupled to the base, and the elastic piece is disposed on the cover Between the body and the base; a bracket is movably mounted inside the central hole of the base; a magnetic component is mounted under the bracket; and an electromagnetic component is mounted under the magnetic component It is located inside the central hole of the base. Therefore, by the action of the magnetic element and the electromagnetic field of the electromagnetic element, the bracket is pushed forward and backward, and the member is composed of the above member, the component can be reduced, the relative volume is reduced, the material Φ is reduced, and the cost is reduced, and the assembly is also simple. . [Embodiment] In order to enable the reviewing committee to better understand the technology, means, and efficacy of the present invention for achieving the intended purpose, please refer to the following detailed description and drawings of the present invention, and the objects, features and features of the present invention are believed. It is to be understood that the invention is not to be construed as limiting the invention. 1286873 i /3⁄4 [Bu Xi's more] 正本口月> As shown in the first figure, it is an exploded perspective view of the steam-type electromagnetic motor of the present invention, and the cylinder-type electromagnetic motor of the present invention includes a base 1 〇, a resilient piece 20, a cover 3〇, a bracket 4〇, a magnetic element 5〇, and an electromagnetic τ member 60, the base 1 has a central hole u for mounting the above components. Since the volume of the susceptor 10 is small, the volume of the entire electromagnetic motor of the present invention can be made small, and the cover body 3 can be coupled and fixed to the susceptor 1 。. The elastic piece 20 is disposed between the cover body 3〇 and the base 1〇, and the elastic piece 2 is provided with a plurality of grooves, and an inner movable portion and an outer fixed portion are formed, and the movable portion can be locked to the bracket. 40, and the fixing portion is locked above the base 1〇. The bracket 40 supports the inner hole 11 of the base 1 by the elastic piece. The bracket 40 can be threaded for screwing a lens 125 into the lock. Since the elastic piece 20 belongs to the flat spring, the elasticity is better and the recovery is faster, so that the moving distance of the bracket 40 is relatively larger. The second figure is a schematic view of the side view of the cylinder type electromagnetic motor of the present invention. The magnetic element 5 is embedded in the bottom of the bracket 40, and the electromagnetic element 60 is embedded under the magnetic element 5〇. It is also located at the bottom of the interior of the central opening 11 of the base. When the electromagnetic element 6 is energized, an electromagnetic field polarity is generated and the magnetic element 50 can be repelled or attracted to generate a thrust to actuate the bracket 40. Conversely, when the electromagnetic element 60 is not energized, the magnet disappears. The elastic restoring force of 20 restores the bracket 4'' to the magnetic element 5''. The magnetic element 50 is a magnet, and the electromagnetic element 6 is an electromagnet. Preferably, the elastic piece 20 is circumferentially corresponding to the periphery of the bracket 4, and the elastic piece 20 and the cover body 30 are provided with a central hole corresponding to the base 1 , so that the 1286873 fl Μ can be installed. The lens 125. By the reduction of the first figure and the second figure - a lower cover, a shrapnel: it can be seen that the present invention shows that the pedestal is also relatively smaller than the conventional ' ^ _ by the control ^ reduce the component, the phase volume is also relative Reducing ^ this can be a good policy. The material is reduced, so the cost is reduced by 0. The principle of actuation of the traditional voice coil motor is also different. The sound culvert =:: Γ? The inner active coil of the magnet 产生 generates magnetic field actuation, and the present invention It is the same as the magnetic field thrust or suction of the bottom solidification. The electromagnet generates the same power as the bottom of the upper movable magnet. In the cylinder operation, the invention is indeed different from the conventional technology disclosed in the lecture. The use value, and its parts, conversion, ^ publications or public use, Cheng has already met the invention patent to file an invention patent application. However, the drawings and descriptions disclosed herein are merely modified by the embodiments of the present invention. Those skilled in the art can make other various types according to the above description, and these changes still belong to the inventive spirit of the present invention and the following. In the patent garden of the boundary. 1286873
