Embodiment 1

[0061] Please refer to Figure 5 , Embodiment 1 of the present invention is:

[0062] On the basis of the traditional DC power supply, the emerging wireless charging function is added to expand the functionality of the wireless PIN pad, and to achieve further portability of the product, reducing the risk of the wireless PIN pad due to insufficient power.

[0063] The power supply system of the wireless PIN pad device includes a traditional external DC power supply and a newly added wireless charging power supply. The traditional external DC charging is used to solve the fast charging of the built-in lithium battery when the system is completely idle; the newly added wireless charging is used to solve the charging of the built-in lithium battery when the product is in use. A switching module is provided between the two power supply modules to ensure that the system currently only has one mode to charge the battery and ensure the safety of the product. The traditional external...

Abstract

The present invention relates to the field of wireless charging, and especially relates to a charging system of a wireless password keyboard, and a charging base. A detection surface of the charging base is provided with a position detection module used for detecting the position of a wireless receiving module of the wireless password keyboard, the position is obtained through the position detection module, then a built-in control module controls a transmitting module to move to the position through a stepping motor, and the transmitting module wirelessly charges the receiving module. Through adoption of the charging system, when the wireless password keyboard enters into an induction area, the position detection module always can accurately position a charging position and enables the transmitting module to move to the optimal charging position for performing wireless charging, thereby achieving automatic correction of the position, and further improving the charging efficiency.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a charging system and a charging base of a wireless password keyboard. Background technique [0002] A wireless charger refers to a charger that is connected to a terminal device that needs to be charged without a traditional charging power cord. This charger using wireless charging technology is convenient to use and breaks the limitation of space. At the same time, users can use a transmitter The charger can charge multiple terminal devices at the same time, and there is no special requirement for the location of the charging terminal devices, which avoids the dilemma that users cannot get rid of the power cord and non-standard unified interface in the process of using the product. For the entire technology industry, retail industry, and service providers, wireless charging technology is of great significance. [0003] As the key input device in the payment process, the tradit...
