[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a POS cash register that can be used for a long time includes a POS machine component 1 and a battery component 2. The POS machine component 1 has a connecting groove 6 on its lower side and a power connector 5 inside the connecting groove 6. The battery component 2 has a connector 10 on its upper rear side and a power connector groove 11 in the middle of the connector 10. The lower part of the battery component 2 is connected to the lower side of the POS machine component 1 through a connecting mechanism, and the lower rear side of the battery component 2 is connected to the lower part of the POS machine component 1 through a fixing mechanism.

[0021] In this embodiment, the outer periphery of the connector 5 is disposed inside the connector slot 11, and the connector 5 is electrically connected to the connector slot 11. The connector 5 is one of the following: a Lightning male connector, a Micro-USB male connector, and a USB Type-C male connector. The battery assembly 2 includes a battery 9, a circuit board 12, and a battery casing 13. The battery 9 and the circuit board 12 are disposed on the front side of the battery casing 13, and the circuit board 12 is disposed on the rear side of the battery 9. The battery 9 is electrically connected to the circuit board 12, and the circuit board 12 is electrically connected to the connector slot 11.

[0022] Specifically, the POS machine component 1 is the host unit of a POS machine disclosed in Chinese Patent Publication No. CN209248692U. When the battery of the POS machine component 1 is depleted, by aligning the limiting groove 8 with the limiting strip 7 and pushing the battery component 2 toward the POS machine component 1, the limiting groove 8 locks the limiting strip 7, preventing the battery component 2 from easily separating from the POS machine component 1. This allows the connector 10 to be inserted into the connector groove 6, thereby allowing the power connector 5 to be accurately inserted into the power connector groove 11. This enables the battery component 2 to supply power to the POS machine component 1, freeing the POS machine component 1 from the constraints of the charging cable and facilitating its use.

[0023] In this embodiment, the connecting mechanism includes a limiting strip 7 and a limiting groove 8. One side of the limiting strip 7 is fixedly connected to the lower left and right sides of the POS machine component 1. The outer periphery of the limiting strip 7 is slidably connected to the inside of the limiting groove 8. The limiting groove 8 is opened on the upper left and right sides of the battery component 2. The cross-section of the limiting strip 7 and the limiting groove 8 is "T" shaped. The fixing mechanism includes a hook 3, a hook groove 4 and a recess. The middle part of the hook 3 is rotatably connected to the lower part of the recess through a torsion spring. The recess is opened on the lower part of the battery shell 13. The hook groove 4 is opened on the lower rear side of the POS machine component 1. The hook 3 is engaged inside the hook groove 4.

[0024] Specifically, when connector 10 is inserted into connector slot 6, hook 3 will be inserted into hook slot 4, which can prevent POS machine component 1 and battery component 2 from detaching. When disassembling, press down on one side of hook 3 located in the groove to disengage hook 3 from hook slot 4, and the battery component 2 can slide out from under the POS machine component 1, which is very convenient to use.

[0025] Working principle:

[0026] When the battery of POS component 1 is depleted, by aligning the limiting groove 8 with the limiting strip 7 and pushing the battery component 2 towards POS component 1, the limiting groove 8 locks the limiting strip 7, preventing the battery component 2 from easily detaching from the POS component 1. This allows the connector 10 to be inserted into the connecting groove 6, and the power connector 5 to be accurately inserted into the power connector slot 11, enabling the battery component 2 to supply power to the POS component 1. This frees the POS component 1 from the constraints of the charging cable, making it more convenient to use. When the connector 10 is engaged in the connecting groove 6, the hook 3 will engage in the hook groove 4, preventing the POS component 1 and battery component 2 from detaching. During disassembly, pressing down on one side of the hook 3 in the groove will disengage the hook 3 from the hook groove 4, allowing the battery component 2 to slide out from under the POS component 1, making it very convenient to use.
