Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] The core idea of the present invention is to use solar energy and / or piezoelectric oscillating energy as an auxiliary energy source to collect microwatt and milliwatt-level energy, convert the collected energy and store it in an auxiliary power source such as a farad capacitor, and use the auxiliary power source to Electronic equipment supplies power to save the power of the main power supply (generally lithium battery), avoid frequent charging of the main power supply (generally lithium battery), and at the same time provide a large peak current for the load. The voltage collected in the auxiliary power supply is monitored through the voltage monitoring circuit, and when the voltage reaches the programmable threshold, the main...

The invention discloses a power supply circuit for electronic equipment, a power supply method and an electronic equipment. The circuit includes: a voltage monitoring circuit, a control circuit, an auxiliary power supply circuit and a main power supply circuit including a battery; the auxiliary power supply circuit is used for collecting energy and converting stored after generating electric energy; the voltage monitoring circuit is used to monitor the voltage of the auxiliary power circuit, and when the voltage of the auxiliary power circuit reaches the first preset value, the first notification signal is sent to the control circuit; when the voltage of the auxiliary power circuit is lower than the second Sending a second notification signal to the control circuit at a preset value; wherein, the first preset value is greater than the second preset value; the control circuit is used to switch the working power circuit of the electronic device to The auxiliary power circuit switches the working power circuit of the electronic device to the main power circuit when receiving the second notification signal. The technical solution of the present invention can prolong the battery life of the electronic device to the greatest extent, thereby improving user experience.
Description
technical field [0001] The invention relates to the field of power supply of electronic equipment, in particular to a power supply circuit of electronic equipment, a power supply method and an electronic equipment. Background technique [0002] At present, smart electronic devices, such as smart bracelets, smart watches, smart glasses, smart buttons, etc., are mostly powered by button batteries or rechargeable lithium batteries. Due to the limited capacity of button batteries, users need to replace them frequently. batteries; and rechargeable lithium batteries are limited by the limited space of electronic equipment, and the battery capacity of lithium batteries generally does not exceed 100mAh. Therefore, the existing electronic equipment has a small capacity of a power supply battery and a short battery life of the electronic equipment, which reduces user experience. Contents of the invention [0003] The present invention provides a power supply circuit of an electroni...
