Description

Wireless charger that can display charging status

technical field

The utility model relates to a wireless charger, in particular to a wireless charger capable of displaying charging status.

Background technique

As we all know, charging the batteries of various portable electronic devices such as mobile phones, personal electronic assistants, and MP3 players is a headache. The socket is very convenient to use. Therefore, a novel device called a "wireless battery charging platform", that is, a wireless charger, has been digitally displayed on the market. The shape of the wireless charger is like the countertop of an electromagnetic cooker. A coupling device that generates a low-frequency electromagnetic field after power-on is installed inside, and an induction energy device that can induce electromagnetic waves is installed on the electronic device that needs to be charged, and it is converted into electrical energy to complete the charging process.

The existing wireless charger mainly transmits the power of the charging platform to the receiving station through the coil. The charging platform cannot detect the power of the battery charged by the transmitting station. The work of the existing wireless charger to detect whether it is full is left to the mobile phone. When the battery is fully charged, the phone will automatically protect the battery to prevent the battery from exploding. This will not only consume the power of the battery, but also the charging platform will always be in working condition, wasting resources.

Utility model content

In order to overcome the disadvantages of the above-mentioned existing wireless chargers, the purpose of this utility model is to provide a wireless charger that can display the charging state, which adopts a battery power detection module in the receiver, and an LCD display at the lower end of the charging platform.

The technical solution adopted in order to realize the purpose of the utility model is: a wireless charger capable of displaying the charging state, characterized in that it is composed of a charger, a charging platform, a receiver, an LCD display screen, and a battery power detection module; The charging platform is square-shaped, with a charger on the left end, a receiver on the right end, an LCD display screen on the lower end, and a wireless output module and a power detection module inside; There is a wireless receiving module and a battery power detection module.

The beneficial effect of the utility model is that it can be used to conveniently charge electronic equipment, and can display battery power on the charging platform, and has simple structure, convenient use and wide application.

Detailed ways

In the first embodiment shown in Figure 1, Figure 2, and Figure 3, a wireless charger that can display charging status is characterized in that it consists of a charger, a charging platform, a receiver, an LCD display, and a battery The detection module is composed of; the charging platform is square in shape, with a charger on the left end, a receiver on the right end, an LCD display screen on the bottom, and a wireless output module and a power detection module inside; the receiver is a square shape, with a wireless receiving module and a battery power detection module inside.

In the second embodiment shown in FIG. 1 , metal contacts are provided on the rear end of the receiver to facilitate the connection between the receiver and the battery.

In the third embodiment shown in Fig. 1, Fig. 2 and Fig. 3, the wireless output module is composed of a switch ADG884, a transmitting circuit ADP3623 and a coil, and is used to convert electric energy into electromagnetic waves; the wireless receiving The module is composed of a coil, a full-wave rectifier circuit, a filter circuit and an ADP1111 step-down regulator chip; the power detection module is a power detection chip, and the utility model adopts ADM1191, and is connected with an LCD display through an MCU; The battery power detection module is composed of ADM1191, MCU and switch ADG884. The input signal of ADM1191 is the two ends of the rechargeable battery, and the output signal is transmitted to the MCU. After the battery power signal is processed, it is transmitted to the coil in the receiver and then transmitted through the charging The demodulation filter comparison circuit inside the platform takes out the battery signal and sends it to the LCD display through the MCU. At the same time, when the charge is saturated, the MCU and the switch ADG884 can control the coil to stop working; the LCD display is used to display the battery power.

When using the utility model, first attach the receiver to the back end of the battery, and connect the metal contacts on the back end of the receiver with the metal contacts of the battery, then plug in the charger, select the charging mode through the LCD display, and start Charging, simple structure, easy to use.
