[0031] Since the outer surface of the signal docking ring is conductive, the connection terminal can be electrically connected to the signal docking ring by contacting the outer surface of the signal docking ring. In the embodiment of the utility model, the connecting lead 240 can lead the corresponding pin of the parameter measurement module to the signal docking ring, and the required parameter information can be read by electrically connecting to the signal docking ring.

[0032] like Figure 2 As shown, the battery assembly cooperates with the battery compartment 300, and an electrical connection pin that penetrates the side wall of the battery compartment 300 along the thickness direction can be set on the side wall of the battery compartment 300. The electrical connection pin is used to further lead the signal of the signal docking ring to the corresponding signal receiving end of the whole machine for processing by the whole machine.

[0033] In the technical solution provided in the embodiment of the utility model, it is only necessary to set a signal docking ring on the outer surface of the battery and an electrical connection pin on the battery compartment to lead the signal in the parameter measurement module to the whole machine side, thereby reducing the manufacturing cost and assembly difficulty.

[0034] It should be noted that the battery 100 is used to power the battery protection board 200, and the positive electrode and the negative electrode of the battery protection board 200 are electrically connected by a flexible printed circuit (FPC). The connecting lead 240 is a corresponding lead in the flexible printed circuit that electrically connects the battery protection board 200 to the positive electrode of the battery 100 and the negative electrode of the battery 100.

[0035] The flexible circuit board is easily deformed and can be attached to the surface of the battery 100 without increasing the volume of the battery 100 or affecting the normal installation of the battery 100 in the battery compartment.

[0036] In the embodiment of the present utility model, the battery can be a battery that can be repeatedly charged and discharged. Therefore, in the embodiment of the present utility model, other functional modules can also be integrated on the battery protection board 200 to realize functions such as charge and discharge voltage detection.

Optionally, the thermistor can be a positive temperature coefficient thermistor or a negative temperature coefficient thermistor (NTC). In order to reduce the operation of electronic devices using battery components as power sources, the thermistor is optionally an NTC.

[0041] In the embodiment of the utility model, the specific structure of the signal docking ring is not particularly limited, as long as its outer surface can be conductive. For example, the signal docking ring can be made of metal material.

[0042] In order to facilitate the installation of the battery assembly into the battery compartment, optionally, the signal docking ring includes a flexible substrate and a conductive layer arranged on the surface of the flexible substrate, the flexible substrate is arranged around the outer circumference of the battery, and the conductive layer is arranged on the surface of the flexible substrate away from the outer circumference of the battery.

[0043] In the embodiment of the utility model, there is no special limitation on the specific material of the conductive layer. For example, the conductive layer can be made of copper or copper alloy.

[0044] In the embodiment of the utility model, the specific form of the battery is not particularly limited. As an optional embodiment, the battery is a cylindrical battery.

[0045] As an optional implementation, the battery 100 may be a 18650 lithium battery or a 21700 lithium battery.

[0046] It should be pointed out that when setting the signal docking ring and connecting the leads, no short circuit should occur between the lines, and the normal operation of the battery protection board and various parameter measurement modules should not be affected.

Specifically, the electrical connection pin penetrates the side wall of the battery compartment 300 along the thickness direction, so that one end of the electrical connection pin is located inside the battery compartment 300, and the other end of the electrical connection pin is located outside the battery compartment 300, and the end of the electrical connection pin located inside the battery compartment 300 is electrically connected to the signal docking ring corresponding to the electrical connection pin.

[0050] It should be pointed out that Figure 2The battery compartment 300 is for illustration only and is not the actual situation, and the battery compartment is not a closed box structure, and electrical signal input terminals or output terminals are provided at required positions.

[0051] In order to ensure the stability of the electrical connection, optionally, the electrical connection pin comprises a spring pin (eg, POGO PIN).

[0055] The "complete machine" here refers to a device that realizes a predetermined function. In the present utility model, there is no special limitation on the specific type of the complete machine, as long as it is a device that needs to be powered by a battery. For example, the complete machine may be an infrared imaging telescope.

[0056] The processor of the whole machine receives the corresponding parameter information output by the parameter measurement module through the electrical connection pin, so that it can operate better.

[0057] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
