Description

Technical Field

[0001] The present invention relates to the technical field of charging pile adaptive voltage, and in particular to a charging pile adaptive voltage and current regulating device. Background Art

[0002] All electronic devices have power supplies, but different systems have different requirements for power supplies. In order to maximize the performance of electronic systems, it is necessary to select the most suitable power management method. Therefore, a power management chip is needed. The power management chip is a chip that is responsible for the conversion, distribution, detection and other power management of electrical energy in electronic equipment systems. It is mainly responsible for identifying the CPU power supply amplitude, generating corresponding short-torque waves, and promoting the power output of the subsequent circuit. It has the characteristics of large power supply, small ripple, and small internal resistance. It can precisely adjust the CPU power supply voltage. In order to optimize the user experience, a charging pile adaptive voltage and current regulation device is proposed.

[0003] After searching, the patent announcement number CN210093122U discloses a power management chip, including a first pin, a second pin, a third pin, a fourth pin, a fifth pin, and a sixth pin.

[0004] The defects of existing low voltage detection power management chips are:

[0005] 1. When installing the existing low voltage detection power management chip, it is usually fixed by spot welding after being plugged into the circuit board. However, the contact area between the solder and the pin is small, resulting in general firmness after soldering.

[0006] 2. The existing low-voltage detection power management chip has average safety protection performance in daily use. It cannot effectively insulate and block fire sources when the power supply device is accidentally short-circuited or in other dangerous situations. The user experience is average. For this reason, we propose a charging pile adaptive voltage and current regulation device to solve the existing problems. Summary of the invention

[0007] The purpose of the present invention is to provide a charging pile adaptive voltage and current regulation device to solve the problems raised in the above background technology.

During the assembly process of the chip body, the staff can connect the pins to the circuit board and then weld and reinforce them. The combination of through holes and rectangular grooves can provide a storage position for solder, which can effectively increase the amount of solder, ensure the structural strength of the chip body after welding, and improve the production quality of the chip body during the assembly process. When the device is used for a long time, the excellent fireproof and insulating properties of the glass fiber board liner can effectively block external and internal fire sources, and at the same time can effectively insulate, improve the safety of the device during power-on operation, and extend the overall service life of the device.

[0010] Preferably, a main transformer is installed on one side of the power supply body, and an auxiliary transformer is installed on the power supply body on one side of the main transformer. The main transformer and the auxiliary transformer are basic components of existing power supply equipment, and the normal operation of the power supply can be ensured by cooperation.

[0011] Preferably, a heat dissipation fan is installed on the top of the top cover, and a protective net is installed on the top of the heat dissipation fan. The heat dissipation capacity of the power supply can be improved by powering on the heat dissipation fan, and the protective net can be used to prevent foreign objects from entering.

[0012] Preferably, a ventilation net is installed on the front of the inspection door, and a socket is installed on one side of the bottom of the inspection door.

The delay control chip can be used to assist the chip body in monitoring and managing the low-voltage power supply, and the connection pin can be used to connect the device to an external power supply and supply power.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a through hole through the inside of the pin, and during the assembly process of the chip body, the staff can insert the pin into the circuit board and then weld and reinforce it, and the cooperation between the through hole and the rectangular groove can provide a storage position for solder, which can effectively increase the amount of solder, ensure the structural strength of the chip body after welding, and improve the production quality of the chip body during the assembly process.
