Pen holder with charging function

Abstract

The invention belongs to the technical field of electronic information and consumption electronics and specifically provides a pen holder with a charging function. The pen holder comprises a pen holder housing, an alternating-current / direct-current conversion circuit, charging interfaces, a button, a power wire and a plug, wherein the alternating-current / direct-current conversion circuit is mounted in a bottom middle position of the pen holder housing. The alternating-current / direct-current conversion circuit is connected with charging interfaces. The two charging interfaces are respectively mounted at left and right sides of the bottom of the pen holder housing. The button is embedded into a position, at the right upper side of the charging interfaces, of the lower part of the pen holder housing. The button is connected with the alternating-current / direct-current conversion circuit. A power wire and the plug are connected to the bottom of the pen holder housing. The power wire and the alternating-current / direct-current conversion circuit are connected. The pen holder solves the problems that an existing pen holder is single in function and existing mobile phone charger interfaces are insufficient. A mobile phone charger is integrated into the pen holder, so that functions are increased to the pen holder, and more charging interfaces are provided. The life of people is relatively convenient.

Description

technical field

[0001] The invention belongs to the technical field of electronic information and consumer electronics, and in particular relates to a pen holder with a charging function. Background technique

[0002] At present, most digital products are powered by rechargeable batteries of about 3.7V. Therefore, making a charger has become a problem that must be considered for each product.

[0003] The current charger basically outputs a voltage of 5V in a small space through a secondary structure of a transformer-stabilized power supply. This circuit structure is very correct, but due to the size of the charger, often only one charging interface can be provided.

[0004] At present, there are more and more digital products in people's hands, so the situation of needing to find multiple chargers will happen from time to time, which brings great inconvenience to people's lives.

[0005] And if it can give a larger volume, it is completely achievable to make 2-3 5V volta...
