Embodiment 1

[0033] like figure 1 As shown, Embodiment 1 of the present invention provides a power supply system for an electronic product. The electronic product includes a casing 1 , and a motor is disposed inside the casing 1 . The motor includes a main body 21 and a vibrator 22 . The power supply system includes: a piezoelectric crystal sheet 3 and an energy storage circuit 4;

[0034] The piezoelectric crystal sheet 3 is tightly fixed between the motor body 21 and the casing 1, and the positive electrode 31 and the negative electrode 32 of the piezoelectric crystal sheet 3 are respectively connected to the positive and negative input ends of the energy storage circuit 4 through wires 71 and 72;

[0035] When the motor vibrates, the piezoelectric crystal sheet 3 is squeezed by the vibration force of the motor to generate current, and the current is output to the main circuit board 5 or the rechargeable battery 6 of the electronic product through the energy storage circuit 4 . Wherein,...

Abstract

The invention discloses a power supply system of an electronic product. Vibration energy of a motor can be converted into electric energy through a piezo-electric crystal and an energy storage circuit tightly fixed between the motor and a housing, and the electric energy is supplied for the electronic product for normal work or is stored in a battery. A part of mechanical energy inevitably consumed by a motor vibration part is converted into electric energy, the influence of high energy consumption of the motor can be offset to some degree, and the power supply system has the advantages of being high in energy utilization rate and turning waste into wealth, has a very good application prospect, can prolong the standby time of the electronic product and facilitates improvement of product competitiveness. The power supply system further comprises a press key installed on the housing. The piezo-electric crystal is pressed through the key, the mechanical energy is converted into electric energy under the situation that the electric quantity of the product is consumed thoroughly and no charging condition is provided temporarily, and power is supplied for the product temporarily to solve the emergency demand.

Description

technical field [0001] The invention relates to a power supply system for electronic products. Background technique [0002] Electronic products, especially wearable products represented by smart watches and smart wristbands, have become more and more popular in the daily life of the public. Restricted by the premise that the appearance design requires compactness and lightness, the battery capacity of this type of electronic product cannot be made very large, so the standby time and use time are limited. As a key part of the event reminder of this type of electronic product, the motor device itself consumes a lot of power. If the user has many phone calls, text messages and other events, the motor vibration frequency is high, and the standby time of such electronic products will be greatly shortened. Contents of the invention [0003] In view of the above problems, the present invention provides a power supply system for electronic products to solve the problem of limit...
