Abstract
The invention belongs to an improved motor structure and relates to a vibration motor, in particular to a thin, flat and linear vibration motor. The improved motor structure comprises an enclosure and a vibration unit and is characterized in that an elastic support part comprises a U-shaped shrapnel; arcs of all bent positions of the shrapnel are smooth and the curvature radius is larger. A chip type large rotary shrapnel is adopted to be used in a narrow space, the conventional design thought of a technician is changed, the structure durability and structure elasticity of the shrapnel can be fully exerted, the impact resistance is greatly enhanced, the vibration use times are greatly increased and the service life of the vibration motor is effectively prolonged.
Description
Technical field
The present invention relates to a kind of vibrating motor, especially a kind of slim flat linear vibrating motor.
Background technology
Slim flat linear vibrating motor of the prior art is in order to adapt to the development of consumption electronic products towards frivolous direction, its motor also needs to adapt to frivolous trend, its designing and making is more and more thinner little, cause thus the space in motor chassis very narrow and small, each parts of motor are all taking Miniaturization Design as prerequisite.And be one of parts of motor most critical as the flexible supporting frames of the vibration unit in motor, it is mainly the motion that stretches and compress, no matter be therefore all to require very highly from structure or material to flexible supporting frames, these parts are also the flimsy parts of appearance of motor.Very narrow and small its structure in space that the flexible supporting frames of prior art is stranded in casing all adopts two-piece type or similar two-piece type elastic clip, if the patent No. is 201220375726X, name is called the patent of " linear vibration motor ", and application number is 2013104744590, name is called the application of " a kind of slim flat linear type vibration motor ", the flexible supporting frames of its vibration unit all adopts two-piece type or similar two-piece type elastic clip, to meet the narrow and small of space in casing, the project organization of this elastic supporting member for supporting optical member, after reaching fatigue strength, elastic supporting member for supporting optical member is easy to occur that elastic supporting member for supporting optical member breaks or elastic failure, and out of use situation, cause cannot using of vibrating motor.And vibration unit, in the time that directions X vibrates, can cause the twisting up and down of Y-direction, make vibration unit clash into casing, also can cause the damage of motor.
Summary of the invention
The present invention has overcome the above-mentioned defect of prior art, and the flexible supporting frames of vibration unit is improved, and adopts single piece type structure, and its resistance to impact strengthens greatly, also can break or deformation failure, can effectively extend the useful life of motor.
Technical scheme of the present invention is: motor with improved structure, comprise casing and vibration unit, and it is characterized in that described elastic supporting member for supporting optical member comprises a shell fragment, the shape of this shell fragment is like " U " shape, and its circular arc of each bending place of this shell fragment is mild, and radius of curvature is larger.
Above-mentioned motor with improved structure, has through hole on the region of the corresponding casing of described permanent magnet, has shielding cover board cover permanent magnet institute corresponding region and seal described through hole on the outer wall of described casing.
Above-mentioned motor with improved structure is fixed with left limit piece and right limit piece on pedestal.
Above-mentioned motor with improved structure, described left limit piece and right limit piece are right angle angle bar shape.
Above-mentioned motor with improved structure, described left limit piece and right limit piece obtain side and are pasted with respectively cushion pad.
Above-mentioned motor with improved structure is provided with shielding upper cover plate on the outer surface of casing.
Above-mentioned motor with improved structure is provided with shielding lower cover on the outer bottom of pedestal.
Technical solution of the present invention adopts the large rotating flexure strip of single piece type to use in narrow space, change the usual Design Thinking of technical staff, can discharge fully and bring into play flexure strip its structure patience and structural elasticity, its resistance to impact strengthens greatly, the number of times that its vibration is used significantly improves, and has effectively extended the useful life of motor.
