[0040] Generally, the safety certification process for lithium batteries is not so strict, while in some countries or regions, the safety certification process for lithium batteries is relatively strict. Taking some countries with relatively strict safety certifications as an example, for lithium batteries sold in these countries, the reverse charging of lithium batteries must be controlled, that is, a reverse protection circuit needs to be added. For some developed circuit boards that need to be sold in these countries, they need to be re-customized, and the development cost is relatively high.
[0041] In the prior art, when it is necessary to sell in countries or regions with relatively strict safety certifications, it is usually necessary to modify the circuit board and customize the product specifically for the standards of certain regions or countries. This method has a high cost. When customizing for different markets and in the case of a small quantity, the cost is very high. Therefore, a solution that can meet different market demands without modifying the circuit board is needed.
[0042] For this reason, the present utility model provides a battery holder structure. Please refer to Figure 1 、 Figure 4 and Figure 5, the battery holder structure includes a mounting base 1, a conductive elastic sheet 2, a voltage conducting and pressing portion 3, and a sheet structure 4. The mounting base 1 has a mounting cavity 11; the conductive elastic sheet 2 is disposed at the bottom of the mounting cavity 11; the voltage conducting and pressing portion 3 is mounted on the side wall of the mounting cavity 11; the sheet structure 4 includes a first conductive layer 41, an insulating layer 42, a second conductive layer 43, and a current limiting structure 44. The first conductive layer 41, the insulating layer 42, and the second conductive layer 43 are arranged in sequence in the up and down direction. The first conductive layer 41 and the second conductive layer 43 are respectively connected in series at both ends of the current limiting structure 44. Among them, the sheet structure 4 can be selectively placed on the conductive elastic sheet 2. When the sheet structure 4 is placed on the conductive elastic sheet 2 and is located in the mounting cavity 11, the second conductive layer 43 is connected to the conductive elastic sheet 2. When the battery structure 200 is pressed on the first conductive layer 41 and is located in the mounting cavity 11, the voltage conducting and pressing portion 3 is connected to the positive electrode of the battery structure 200, and the first conductive layer 41 is connected to the negative electrode of the battery structure 200.
[0043] Please refer to Figure 2 and Figure 3 , when the current limiting structure 44 needs to be set, first install the sheet structure 4 into the mounting cavity 11 with the first conductive layer 41 facing outward and the second conductive layer 43 pressed on the conductive elastic sheet 2. Then place the battery structure 200 on the first conductive layer 41 and accommodate it in the mounting cavity 11. At this time, the negative electrode of the battery structure 200 is electrically connected to the first conductive layer 41, and the positive electrode of the battery structure 200 is connected to the voltage conducting and pressing portion 3. When the current limiting structure 44 does not need to be set, directly install the battery structure 200 into the mounting cavity 11. The negative electrode of the battery structure 200 is elastically pressed against the conductive elastic sheet 2, and the positive electrode of the battery structure 200 is electrically connected to the voltage conducting and pressing portion 3. Whether to set the current limiting structure 44 specifically can be set according to requirements, thus solving the situation that there are different safety certification requirements when the product is sold in different countries or regions, avoiding modifying the circuit board, and reducing the modification cost.
[0044] Specifically, the sheet structure 4 includes an FPC board and the current limiting structure 44. The FPC board includes the first conductive layer 41, the insulating layer 42, and the second conductive layer 43 that are stacked together in sequence in the up and down direction. During installation, first install the FPC board into the mounting cavity 11, and the current limiting structure 44 is disposed outside the mounting cavity 11.
[0045] In addition, the shape of the FPC board matches the shape of the bottom of the mounting cavity 11, so that it is convenient for the FPC board to be installed in the mounting cavity 11 and remain stable, avoiding deviation.
[0046] Since the first conductive layer 41 is press-connected to the negative electrode of the battery structure 200, to ensure good contact between the first conductive layer 41 and the negative electrode of the battery structure 200, the surface area of the first conductive layer 41 is A, and the surface area of the negative electrode of the battery structure 200 is B, where A > B.
[0047] More specifically, the sheet structure 4 further includes a first conductive portion and a second conductive portion. One end of the first conductive portion is electrically connected to the first conductive layer 41, the other end of the first conductive portion extends out of the installation cavity 11 and is electrically connected to one end of the current-limiting structure 44, one end of the second conductive portion is electrically connected to the second conductive layer 43, and the other end of the second conductive portion extends out of the installation cavity 11 and is electrically connected to the other end of the current-limiting structure 44.
[0048] In this embodiment, the current-limiting structure 44 is a resistor structure with a preset resistance value. For example, the resistance value of the resistor structure is 10k.
[0049] The present utility model also provides a battery device. Please refer to Figure 1 This battery device includes the above battery seat structure and the battery structure 200, and the battery structure 200 is installed in the installation cavity 11 of the battery seat structure.
[0050] When the current-limiting structure 44 needs to be provided, first install the sheet structure 4 into the installation cavity 11 with the first conductive layer 41 facing outward and the second conductive layer 43 press-connected to the conductive elastic sheet 2. Then place the battery structure 200 on the first conductive layer 41 and accommodate it in the installation cavity 11. At this time, the negative electrode of the battery structure 200 is electrically connected to the first conductive layer 41, and the positive electrode of the battery structure 200 is electrically connected to the voltage-conducting connection portion 3. When the current-limiting structure 44 does not need to be provided, directly install the battery structure 200 into the installation cavity 11, and the negative electrode of the battery structure 200 is elastically press-connected to the conductive elastic sheet 2, and the positive electrode of the battery structure 200 is electrically connected to the voltage-conducting connection portion 3. Whether to provide the current-limiting structure 44 specifically can be set according to requirements.
[0051] In addition, the battery structure 200 is arranged in a rounded rectangular structure, and both ends of the battery structure 200 have arc-shaped ends; during installation, the arc-shaped ends are arranged close to the voltage-conducting connection portion 3.
[0052] The embodiments of this battery device include the embodiments of the battery seat structure, and the beneficial effects of the above battery seat structure can be applied to this battery device.
