[0030] Furthermore, a power management circuit is configured on the circuit board 3. The power management circuit preferentially uses the mains power when the mains power line is connected, and then uses the cylindrical battery 50 or 18650 battery for power supply after the mains power is disconnected.

[0031] Furthermore, the cylindrical battery 50 is a No. 1 battery.

[0032] Furthermore, if Figure 7 As shown, a cover plate 9 is detachably provided on the battery compartment 2 , and a power switch 10 is provided on the surface of the base 1 . The power switch 10 is electrically connected to the circuit board 3 inside the base 1 to control the power switch of the battery compartment 2 .

[0033] Furthermore, the polarities of the electrode sheets of two adjacent groups of electrode pairs 4 on the same side wall of the rectangular groove are different.

[0034] Furthermore, a slot 11 for routing power cables is provided on the surface of the base 1 .

[0035] Furthermore, a plurality of heat dissipation holes 12 communicating with the interior are provided on the surface of the base 1 .

[0036] Furthermore, if Figures 4 to 6 As shown in FIG1 , the outer contour of the 18650 battery 20 is rectangular, and the mounting groove 5 is a rectangular structure.

[0037] Furthermore, if Figures 4 to 6 One, the 18650 battery 20 includes a middle body 24, an upper cover 25 is detachably provided in the upper opening of the middle body 24, and a detachable lower cover 26 is provided at the bottom of the middle body 24.

A plurality of retaining plates 22 are located on either side of the bottom of the 18650 battery 20. When the 18650 battery 20 is slidably inserted into the mounting slot 5, the retaining plates 22 engage with the hooks 51 and securely engage with them. When the electrode plug 21 of the 18650 battery 20 slides within the elongated socket 6, the connecting copper block 7 within the elongated socket 6 maintains contact and connection with the conductive spring pins 23 within the electrode plug 21.

[0042] Furthermore, if Figure 6 As shown, a matching groove 32 is provided on the bottom end surface of the insulating column 30 corresponding to the conductive spring pin 23. When the electrode plug 21 is inserted into the long socket 6, the connecting copper block 7 in the long socket 6 is pressed into the matching groove 32 to contact and connect with the conductive spring pin 23.

[0043] The specific working principle of the present invention is described in detail below:

[0044] like Figure 1 As shown, the present invention provides the following power supply modes:

[0045] 1. Mains power supply mode: Connect the mains cable to the mains interface 8 provided in the mounting slot 5 of the battery compartment 2, and then cover the battery compartment 2 cover 9. At this time, the battery compartment can be connected to the mains to power the electronic product, and the power supply line can be reliably restricted to the outer shell of the base 1 through the card slot 11 on the outer shell.

[0046] 2. Combined power supply mode: Two combined power supply modes are provided, taking the cylindrical battery 50 using No. 1 battery as an example.

[0047] (1) A battery compartment 2 for mains power plus three No. 1 batteries. Inside this battery compartment 2, there are electrode pairs 4 of cylindrical batteries 50. Three No. 1 batteries are placed inside the battery compartment 2, and a mains power interface 8 space is left inside the battery compartment 2 to ensure that the mains power supply line can be normally connected after the three No. 1 batteries are installed. Figure 2 When three D-cell batteries are installed in the battery compartment 2 and connected to the mains power line, the battery compartment will prioritize using the mains power to power the electronic product. In the event of a power outage or when the product needs to be moved and disconnected from the mains power, it will automatically switch to battery power.

[0048] (2) A battery compartment 2 for power supply with a mains power and 18650 battery 20 module. In the current electronic products on the market that are powered by a combination of mains power and batteries, the batteries are all fixed to a certain specification, which cannot meet the actual use needs of different customers. Therefore, the present invention now provides a battery compartment 2 that can not only install 3 No. 1 dry batteries, but also can interchangeably install and use a 18650 battery 20, such as Figure 3 shown.

[0049] like Figure 1 As shown, a mounting slot 5 is left in the middle of the battery compartment 2, and two long strip-shaped connecting copper blocks 7 are welded on the circuit board 3 at the corresponding long strip sockets 6 at the mounting slot 5; Figures 4 to 6 As shown in Figure 1, two conductive pogo pins are soldered to the circuit board 3 inside the corresponding 18650 battery 20. When using the mains power plus 18650 battery module 20 power supply mode, the 18650 battery module 20 is installed in the mounting slot 5 of the battery compartment 2 using a slide rail. The two pogo pins connect to the two long copper blocks inside the battery compartment 2 for electrical connection, and are securely fixed to the battery compartment 2 body by the stopper 22.

[0050] When 18650 batteries 20 are installed in the battery compartment 2, the mains power cord can be plugged into the mains power port 29 provided on the 18650 battery 20. At this point, the mains power cord can only be electrically connected to the electronic product through the mains power port 29 of the 18650 battery module (because installing the 18650 battery module will block the mains power port 8 on the base). As an embodiment, the battery compartment preferentially uses the mains power from the mains power port 29 to power the electronic product, while the mains power also charges the 18650 batteries 20. In the event of a sudden power outage or when the product needs to be moved and disconnected from the mains power, the battery compartment automatically switches to using the 18650 batteries to power the electronic product.

[0051] The present invention adopts the above technical solution. A single battery compartment 2 can be compatible with both mains power supply and mains power plus battery power supply. It also accommodates three D-cell batteries and 20 18650 battery modules. This meets the practical needs of different customers, regions, and usage habits, while also improving the product's aesthetics and ensuring its safety.

[0052] Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
