Mobile phone motor with vibrating heat-radiating function

Abstract

The invention discloses a mobile phone motor with a vibrating heat-radiating function. The mobile phone motor comprises a motor transmission shaft, a vibrating device and a heat radiating device, wherein the vibrating device and the heat radiating device are connected with the motor transmission shaft. After the motor is started, the motor transmission shaft drives the vibrating device and the heat radiating device to rotate. The vibrating device adopts eccentric gears as vibrators. When the motor rotates forward, one vibrator can drive the other vibrator to rotate synchronously at high speed to form eccentric force and generate vibrating. When the motor rotate reversely, the two vibrators abuts against paddles and are separate from each other to recover to a balanced state and stops vibrating, and the fan of the heat radiating device continue to rotate and radiate heat synchronously under the rotation of the motor transmission shaft. A vibrating state and a heat radiating state can operate synchronously or only the heat radiating state operates through the conversion of the positions of the vibrators. Under a non-vibrating state, the fan rotate with the motor synchronously, the heat radiating function is achieved, and the bottleneck that the fan can start heat radiating only when the rotators vibrate is avoided through the separating working mode.

Description

technical field [0001] The invention relates to a motor, in particular to a motor arranged on a mobile phone to realize vibration and heat dissipation. Background technique [0002] At present, mobile phones have become one of the necessities of human social life. Since the birth of capacitive touch screen mobile phones in 2007, a new wave of rapid development of mobile phones has come. Higher frequency, larger screen, and thinner size have become the main selling points of mobile phones, but the heat dissipation problem has also become a major factor restricting the development of mobile phones. More and more people complain that mobile phones are seriously overheated. Since most mobile phones use a front screen, a back battery, and a plastic shell, these materials are not conducive to heat dissipation, so it is imperative to add a heat dissipation module to the mobile phone. [0003] At present, the main heat dissipation method used in mobile phones is passive: use some m...

AI Technical Summary

Problems solved by technology

[0004] Passive heat dissipation first increases the cost of mobile phones, and secondly increases the complexity of mobile phone production. Designers should also pre-design and add some heat-conducting metal sheets to cooperate with heat dissipation, which is not conducive to thinning and thinning mobile phones.

The most important thing is that the heat dissipation rate of passive heat dissipation is low, and the heat is more evenly distributed to all parts of the mobile phone. After a period of use, the mobile phone will still become relatively hot because the heat cannot be effectively dissipated to the outside of the mobile phone.
