Embodiment Construction

[0028] It can be seen from the background art that in the prior art, when the load device communicates with the terminal, the operation of the load device will be affected by the power supply performance of the terminal.

[0029] In order to solve the above problem, the present invention provides a charging circuit, which can be connected to the charger and the terminal at the same time, and after the charging circuit is connected to the charger, it can control the terminal to stop power supply and the charger to start power supply, so that the terminal is running on its own while There is no need to supply power to the outside, avoiding the cascading impact on the operation of the load equipment caused by the performance degradation of the terminal affected by the power supply task; in addition, the protocol chip will not be powered off during the power supply delay of the terminal, which is beneficial to avoid the operation of the load equipment due to the terminal's The powe...

Abstract

The embodiment of the invention provides a charging circuit which comprises a first port of a terminal, a second port used for being connected with a charger and a third port used for being connected with load equipment, and the terminal and the charger being used for supplying power to the load equipment; a protocol chip, used for acquiring whether the second port is connected with the charger or not, and controlling the terminal to stop supplying power and controlling the charger to start supplying power when the second port is connected with the charger; the charging circuit further comprises a power supply module and a delay chip, the protocol chip is further used for controlling the terminal to start power supply when the charger stops power supply, the terminal has power supply delay time, and the power supply delay time comprises the longest time interval needed from power supply stopping to power supply starting. And the delay chip is used for controlling the power supply module to supply power to the protocol chip within the power supply delay time. The circuit is beneficial to improving the use experience of the load equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic equipment, and in particular to a charging circuit. Background technique [0002] With the popularity of AR and other payloads and the diversification of their functions, people began to use AR and other payloads as an accessory for daily terminals in the industrial and gaming fields. In this way, the performance of load devices such as AR and daily terminals can be integrated, so that users can have a better experience. [0003] In practical application scenarios, the terminal usually not only needs to communicate and interact with load devices such as AR, but also needs to supply power to the load device, which makes the power supply performance of the terminal affect the operation of the load device. Contents of the invention [0004] The embodiment of the present invention provides a charging circuit, which helps to solve the problem that the actual operation of the load devi...
