Description

Technical Field

[0001] The utility model relates to the technical field of power supply boxes, in particular to an embedded UPS direct current power supply. Background Art

[0002] With the continuous development of electronic technology, smart homes have begun to enter our lives, and more and more people will use smart homes when decorating. But this also leads to certain requirements for electricity. For example, the commonly used smart locks, some glass doors have narrow door frames and cannot use large smart locks. Only small smart locks can be used. A separate wire is needed to power the smart lock, but occasionally the power company will overhaul the power, resulting in power failure. At this time, the smart lock cannot be used. For this reason, a power box will be installed during decoration to power some important small appliances. In order to ensure that they can still be used during power outages, a battery will be installed inside the power box.

[0003] The installation of existing charging power supplies requires special slots, which is time-consuming and labor-intensive. Moreover, the lithium battery is in a floating charge state for a long time, which will accelerate the degradation of the lithium battery performance. The traditional method is to recharge the lithium battery when the circuit detects that the lithium battery voltage is lower than the upper limit voltage. However, this will frequently start the charging and discharging of the lithium battery, which will accelerate the degradation of the lithium battery's service life. Utility Model Content

[0004] The purpose of the utility model is to provide an embedded UPS direct current power supply to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an embedded UPS DC power supply, including an installation box, a front end of the installation box is fixedly connected to a mounting platform, the upper and lower sides of the installation platform are provided with fixed card slots, a control module placement slot is provided inside the installation box, a fixing plate is fixedly connected inside the control module placement slot, a lithium battery compartment is provided in the middle of the installation box, the lithium battery compartment is located below the control module placement slot, a plurality of heat dissipation ports are provided at the upper end of the installation box, the heat dissipation ports are connected to the control module placement slot, and two positioning slots are provided on the back of the installation box.

[0006] Preferably, a fixed connection hole is provided in the middle of the positioning groove, the fixed connection hole passes through the installation box, and the control module placement groove is located in the middle of the two positioning grooves.

[0007] Preferably, a wiring port is provided at the upper end of the positioning groove, and the upper end of the installation box is a T-shaped structure in a top view, with three input wire holes provided at the left wiring port and two output wire holes provided at the right wiring port.

[0008] Preferably, a lithium battery and a wide voltage power compensation control module are placed in the lithium battery compartment, and the lithium battery is electrically connected to the power grid via the wide voltage power compensation control module.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the installation box can be directly snapped and fixedly connected in the traditional switch box and socket box, so that the installation box can be embedded in the inside of the wall. The installation is simple and convenient, and it is compatible with standard parts on the market, and no special slotting is required for installation. When the mains power of the power grid is input, the DC output is used to power the smart lock and small electrical appliances through the switching power supply transformation, and the lithium battery in the lithium battery compartment is also powered. When the mains power is cut off, the UPS power supply starts, and the circuit connection is controlled through the wide voltage replenishment control module to ensure that the battery can supply power stably. This power supply can power the smart lock through the internal battery after the power grid is cut off, and can also power some small household appliances to ensure that the smart lock and small household appliances continue to work; at the same time, the UPS DC power supply design can control the value of the lithium battery charging voltage, and only charge when the voltage is lower than 7.8V, which greatly reduces the number of charge and discharge times in the standby state, thereby extending the service life of the lithium battery and improving the product's performance.
