[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The battery module 100 includes a housing 1, which comprises an upper housing 11, a lower housing 12, a front housing 13, and a rear housing 14. The upper housing 11 is provided with a sound outlet 111. A lithium battery 2, compatible with four small batteries, is disposed inside the housing 1. A first circuit board 3 is disposed inside the housing 1, and the lithium battery 2 is electrically connected to the first circuit board 3. The first circuit board 3 includes a first side 31 and a second side 32, which are arranged opposite to each other. The first side 31 faces the inner cavity of the housing 1, and the second side 32 faces the upper housing 11. A buzzer 33 is connected to the first circuit board 3 and is disposed on the first side 31. The buzzer 33 is used to provide an audible alert when the power of the lithium battery 2 is lower than a preset value, and outputs sound through the sound outlet 111. With this design, the placement of the buzzer 33 in this battery module 100 enables the battery module 100 to provide a low-battery alarm while also achieving miniaturization and portability.

[0025] In some embodiments, the battery module 100 further includes a power display screen 4. The upper housing 11 is provided with a first opening 112. The shape of the first opening 112 can be circular, square, or other shapes. The power display screen 4 is disposed in the first opening 112 and is electrically connected to the second side 32. The power display screen 4 is used to display the power of the lithium battery 2.

[0026] In some embodiments, the battery module 100 further includes a switch button 5. Pressing the switch button 5 causes the power display screen 4 to show the power level of the lithium battery 2, while pressing and holding the switch button 5 turns the battery module 100 on or off. The upper housing 11 is provided with a second opening 113, and the switch button 5 is disposed in the second opening 113 and electrically connected to the second side 32. The second opening 113 and the first opening 112 are arranged adjacent to each other, and the first opening 112 is closer to the rear housing 14 than the second opening 113, so that the user's hand does not obstruct the power display screen 4 when pressing the switch button 5.

[0027] In some embodiments, the battery module 100 further includes a Type-C port 6. The upper housing 11 has a third opening 114, and the Type-C port 6 is disposed in the third opening 114. The Type-C port 6 is electrically connected to the second side 32, and the battery is charged through the Type-C port 6. The third opening 114 and the second opening 113 are arranged adjacent to each other, and the second opening 113 is closer to the rear housing 14 than the third opening 114. This way, when the user charges the battery through the Type-C port 6, the charging cable will not obstruct the switch button 5 and the power display screen 4.

[0028] In some embodiments, the battery module 100 further includes a second circuit board 7 and a USB port 8, through which the charging output of the battery module 100 is realized. The second circuit board 7 and the first circuit board 3 are arranged vertically, and the second circuit board 7 is closer to the upper housing 11 than the first circuit board 3. The second circuit board 7 includes a third side 71 and a fourth side (not shown in the figure), which are arranged opposite to each other. The third side 71 is closer to the first circuit board 3 than the fourth side (not shown in the figure). The lower housing 12 includes a fourth opening 115, and the USB port 8 is disposed in the fourth opening 115 and electrically connected to the second circuit board 7. Specifically, the USB port 8 is electrically connected to the fourth side (not shown in the figure) of the second circuit board 7.

[0029] In some embodiments, the lithium battery 2 is located further away from the front housing 13 than the first circuit board 3. This arrangement allows for miniaturization of the battery module 100.

[0030] In some embodiments, the front housing 13 and the rear housing 14 are respectively provided with a first positive metal contact 131 and a second negative metal contact 141. The first positive metal contact 131 is used to connect to the positive electrode material inside the lithium battery 2, and the second negative metal contact 141 is used to connect to the negative electrode material inside the lithium battery 2.

[0031] In some embodiments, the battery module 100 is applied to a carrier device (not shown), such as a tissue dispenser, hand dryer, etc. The carrier device has a battery compartment (not shown) to house the battery module 100. The battery compartment is connected to a circuit (not shown), which is electrically connected to a second circuit board 7. A diode (not shown) is installed on the circuit. When the first positive metal contact 131 is electrically connected to the positive terminal of the diode, the second circuit board 7 operates normally, and therefore the USB port 8 electrically connected to the second circuit board 7 also operates normally, supplying power to the carrier device via the lithium battery 2 through the USB port 8. However, when the second negative metal contact 141 is electrically connected to the negative terminal of the diode, the second circuit board 7 does not operate normally, and therefore the USB port 8 electrically connected to the second circuit board 7 also does not operate normally. The lithium battery 2 then supplies power to the carrier device via the USB port 8, thus preventing the lithium battery from supplying power to the carrier device even when the connection is reversed, and avoiding damage to the carrier device and the lithium battery 2.

[0032] In some embodiments, the battery module 100 is also provided with a temperature sensor (not shown in the figure). The temperature sensor is disposed on the lithium battery 2 and is used to detect the temperature of the lithium battery 2. An MCU (not shown in the figure) is disposed on the first circuit board 3. The MCU stores the highest preset temperature of the lithium battery 2. When the temperature sensor senses that the temperature of the lithium battery 2 is higher than the highest preset temperature, the MCU enables the power-off protection function and stops the lithium battery 2 from working.

[0033] In this utility model, unless otherwise explicitly specified or limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; they can be a connection within two components, or merely surface contact, or a surface contact connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.
