Improved motor structure

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 [0001] The invention relates to a vibration motor, in particular to a thin flat linear vibration motor. Background technique [0002] The thin flat linear vibration motor in the prior art is in order to adapt to the light and thin development of consumer electronic products, the motor also needs to adapt to the light and thin trend, and its design and manufacture are becoming thinner and thinner, resulting in the space in the motor casing It is very small, and all parts of the motor are designed on the premise of miniaturization. The elastic support frame as the vibration unit in the motor is one of the most critical parts of the motor. It is mainly the movement of stretching and compression. Therefore, the elastic support frame has very high requirements in terms of structure and material. This part is also The most vulnerable part of the motor. The prior art elastic support frame has a very narrow space trapped in the casing, and its structure adopts two-piece...

AI Technical Summary

Problems solved by technology

The elastic support frame in the prior art is trapped in a very narrow space in the casing, and its structure adopts two-piece or similar two-piece elastic clips, such as the patent No. 201220375726X, the patent named "Linear Vibration Motor", and the application No. For the application of 2013104744590 titled "A Thin Flat Linear Vibration Motor", the elastic support frame of the vibration unit adopts two-piece or similar two-piece elastic clips to meet the narrow space inside the casing. This elastic support Due to the design structure of the parts, after the elastic support reaches the fatigue strength, it is easy for the elastic support to break or elastically fail, and it cannot be used, resulting in the failure of the vibration motor.

And when the vibrating unit vibrates in the X direction, it will cause up and down twisting in the Y direction, causing the vibrating unit to hit the casing, which will also cause damage to the motor
