[0037] refer to Figures 1 to 7 , the present application embodiment provides a battery pack 10, including: Figure 1 , a housing 100, a first output interface 302, a second output interface 202 and a battery cell 400, the housing 100 includes a bottom box 200 and an upper cover 300, the bottom box 200 and the upper cover 300 enclose a receiving space 101, the upper cover 300 has a protrusion 301 protruding in a direction away from the receiving space 101, and the bottom box 200 has a groove 201 recessed in a direction close to the receiving space 101; combined with reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , the first output interface 302 is disposed on the outer wall of the protruding portion 301, and is used to be electrically connected to the first electrical device 501; Figure 1 , Figure 3 , Figure 6 and Figure 7 , the second output interface 202 is disposed on the inner wall of the groove portion 201, and is used to be electrically connected to the second electrical device 502; Figure 1 The battery cell 400 is accommodated in the receiving space 101 of the shell 100 , and the output end of the battery cell 400 is electrically connected to the first output interface 302 and to the second output interface 202 .

[0038] In the battery pack 10 provided in the embodiment of the present application, the shell 100 includes a bottom box 200 and an upper cover 300. The receiving space 101 surrounded by the bottom box 200 and the upper cover 300 can be used to accommodate the battery cell 400. The shell 100 can protect the battery cell 400 to prevent the battery cell 400 from being affected by environmental factors during use, thereby improving the stability of the battery pack 10. The upper cover 300 has a protruding portion 301 protruding in a direction away from the receiving space 101, and the first output interface 302 is arranged on the outer wall of the protruding portion 301, which is used to be electrically connected to the first electrical device. In this way, the battery pack 10 can match the first electrical device through the protruding portion 301 of the upper cover 300, thereby supplying power to the first electrical device; the bottom box 200 has a groove portion 201 recessed in a direction close to the receiving space 101, and the second output interface 202 is arranged on the inner wall of the groove portion 201, which is used to be electrically connected to the second electrical device. In this way, the battery pack 10 can also match the second electrical device through the groove portion 201 of the bottom box 200, thereby supplying power to the second electrical device. By respectively arranging the groove portion 201 and the protruding portion 301 on the bottom box 200 and the upper cover 300, the battery pack 10 can have output interfaces of different shapes to match different electrical devices respectively, thereby improving the compatibility of the battery pack 10.

[0039] It is understandable that the specific shape of the groove 201 of the bottom box 200 and the specific shape of the protrusion 301 of the upper cover 300 can be designed according to the shape of the corresponding electrical equipment to be adapted. The drawings provided in this embodiment do not constitute a limitation on the specific shapes of the groove 201 and the protrusion 301.

[0040] In the drawings provided in this embodiment, taking the example that both the first output interface 302 and the second output interface 202 are plug-in slots, the corresponding first electrical device is provided with a connection plug that matches the first output interface 302, and the second electrical device is provided with a connection plug that matches the second output interface 202. That is, the connection between the output interface of the battery pack 10 and the electrical device is a plug-in connection.

[0041] In some embodiments, the connection between the output interface of the battery pack and the electrical device may also be a contact-type connection. The shapes of the corresponding first output interface and the second output interface may be set to a point contact structure.

[0042] In some embodiments, reference Figure 1 and Figure 2The battery pack 10 may further include: a circuit board 600, the circuit board 600 is disposed in the housing 100, the circuit board 600 is electrically connected to the battery cell 400, the first output interface 302 and the second output interface 202 are both electrically connected to the circuit board 600, and the circuit board 600 controls the conduction between the first output interface 302 or the second output interface 202 and the battery cell 400. That is, the circuit board 600 can control whether the first output interface 302 or the second output interface 202 outputs a voltage, for example, referring to Figure 5 , when the circuit board 600 detects that the first output interface 302 is connected to the first power-consuming device 501, the voltage is output to the first power-consuming device 501 through the first output interface 302; or, refer to Figure 7 When the circuit board 600 detects that the second output interface 202 is connected to the second power-consuming device 502, the voltage is output to the second power-consuming device through the second output interface 202. By controlling the conduction between the first output interface 302 or the second output interface 202 and the battery cell 400 through the circuit board 600, it is possible to avoid leakage of the second output interface 202 when the battery pack 10 is mounted on the first power-consuming device 501, or to avoid leakage of the first output interface 302 when the battery pack 10 is mounted on the second power-consuming device 502, so as to improve the stability of the battery pack 10.

[0043] In some embodiments, the circuit board 600 may further include a voltage control circuit for controlling the output voltage of the first output interface 302 or the output voltage of the second output interface 202. In this way, the output voltage of the first output interface 302 may be controlled to be the same as or different from the output voltage of the second output interface 202 through the circuit board 600, so as to adapt to the first power-consuming device 501 and the second power-consuming device 502 with different power voltages or the same power voltage, thereby improving the compatibility of the battery pack 10.

[0044] It should be noted that in Figures 4 to 7 As an example, the first electrical device 501 is an electric glue gun and the second electrical device 502 is an electric blower, which does not constitute a limitation on the device types of the first electrical device 501 and the second electrical device 502. In actual application scenarios, the first electrical device and the second electrical device can also be other electrical devices or equipment such as garden tools, electric tools, and household appliances that require battery packs for power supply.

[0045] In some embodiments, in conjunction with reference Figure 2 , Figure 4 and Figure 5The first output interface 302 is provided on the outer wall of the protrusion 301 on one side along the first direction X, and the outer walls of the protrusion 301 on both sides along the second direction Y are provided with first guide grooves 303, and the first guide grooves 303 are used to engage with the first electrical device 501, and the first direction X intersects with the second direction Y. In this way, when the battery pack 10 is matched with the first electrical device 501, the protrusion 301 slides along the direction of the first guide groove 303 to match the groove structure with a complementary shape on the first electrical device 501, and the first guide groove 303 can limit the installation direction of the battery pack 10, and is also conducive to improving the installation stability of the battery pack 10 and the first electrical device 501.

[0046] In some embodiments, the extension direction of the first output interface 302 is parallel to the extension direction of the first guide slot 303. It is understandable that when the first output interface 302 is a plug-in slot, a corresponding connecting plug is provided in the groove interface on the first electrical device 501 that matches the battery pack 10. When the battery pack 10 slides along the first guide slot 303, the extension direction of the first output interface 302 is parallel to the extension direction of the first guide slot 303, which can facilitate the smooth insertion of the connecting plug into the plug-in slot, thereby improving the electrical connection stability between the battery pack 10 and the first electrical device 501.

[0047] In some embodiments, the extension direction of the first output interface may not be parallel to the extension direction of the first guide slot. For example, when the first output interface is a point contact structure, the connection between the first output interface and the first electrical device is point contact, and as long as the first output interface moves to the electrical contact point of the first electrical device, the movement of the battery pack along the first guide slot does not affect the electrical connection between the first output interface and the first electrical device, then the extension direction of the first output interface may not be parallel to the extension direction of the first guide slot.

[0048] In some embodiments, in conjunction with reference Figure 3 , Figure 6 and Figure 7 The second output interface 202 is arranged on the inner wall of the groove portion 201 on one side along the first direction X, and the inner walls of the groove portion 201 on both sides along the second direction Y are provided with second guide grooves 203, and the second guide grooves 203 are used to engage with the second electrical device 502, and the first direction X intersects with the second direction Y. In this way, when the battery pack 10 is matched with the second electrical device 502, the groove portion 201 slides along the direction of the second guide groove 203 to match the protruding structure of the second electrical device 502 with a complementary shape, and the second guide groove 203 can limit the installation direction of the battery pack 10, and is also conducive to improving the installation stability of the battery pack 10 and the second electrical device 502.

[0049] In some embodiments, the extension direction of the second output interface 202 is parallel to the extension direction of the second guide slot. It is understandable that when the second output interface 202 is a plug-in slot, a corresponding connecting plug is provided on the protruding interface on the second electrical device 502 that matches the battery pack 10. When the battery pack 10 slides along the second guide slot 203, the extension direction of the second output interface 202 is parallel to the extension direction of the second guide slot 203, which can facilitate the smooth insertion of the connecting plug into the plug-in slot, thereby improving the electrical connection stability between the battery pack 10 and the second electrical device 502.

[0050] In some embodiments, the extension direction of the second output interface may not be parallel to the extension direction of the second guide slot. For example, when the second output interface is a point contact structure, the connection between the second output interface and the second electrical device is point contact. As long as the second output interface moves to the electrical contact point of the second electrical device, the movement of the battery pack along the second guide slot does not affect the electrical connection between the second output interface and the second electrical device. In this case, the extension direction of the second output interface may not be parallel to the extension direction of the second guide slot.

[0051] exist Figures 1 to 3 In the example, the first direction X is the length direction of the battery pack 10, and the second direction Y is the width direction of the battery pack 10, that is, the angle between the first direction X and the second direction Y is 90°. In other embodiments, the angle between the first direction and the second direction can also be 30°, 45°, or 60°, etc., so that when the battery pack is connected to the first electrical device through the first guide groove along the first direction, the first output interface can be electrically connected to the first electrical device.

[0052] In some embodiments, reference Figure 2 A buckle 601 is provided on the surface of the protrusion 301 away from the bottom box 200, and the buckle 601 can be engaged with the first electrical device 501, so as to improve the stability of the battery pack 10 and the first electrical device 501 after installation, and avoid the problem of the first electrical device 501 and the battery pack 10 falling off during the use of the first electrical device 501.

[0053] In some embodiments, reference Figure 3 A card slot 602 is provided on the surface of the groove portion 201 away from the upper cover 300, and the card slot 602 can be engaged with the second electrical device 502, so as to improve the stability of the battery pack 10 and the second electrical device 502 after installation, and avoid the problem of the second electrical device 502 and the battery pack 10 falling off during the use of the second electrical device 502.

[0054] In some embodiments, the side surface of the bottom box 200 away from the upper cover 300 is parallel to the side surface of the upper cover 300 away from the bottom box 200. That is, the top and bottom surfaces of the battery pack 10 are both set to a flat structure. Figure 5 When the battery pack 10 is installed on the first electrical device 501, the bottom surface of the bottom box 200 serves as the bottom surface of the assembled first electrical device 501. The bottom surface of the bottom box 200 is a flat structure, which can facilitate placing the assembled first electrical device 501 on a desktop or bottom surface; or refer to Figure 7 When the battery pack 10 is installed on the second electrical device 502, the top surface of the upper cover 300 serves as the bottom surface of the assembled second electrical device 502. The top surface of the upper cover 300 is a flat structure, and the assembled second electrical device 502 can be placed on a desktop or bottom surface.

[0055] In some embodiments, reference Figure 1 The battery pack 10 may further include: a power display board 700, which is electrically connected to the battery cell 400 and is used to display the remaining power of the battery cell 400; the side wall of the bottom box 200 has a visual window 207, and the power display board 700 is arranged in the receiving space 101, and the power display board 700 is located on the inner wall of the bottom box 200 facing the visual window 207. In this way, the remaining power of the battery pack 10 can be observed through the visual window 207, which is convenient for users to use.

[0056] It should be noted that in Figure 1 The number of battery cells 400 shown in the figure is not sufficient to limit the battery cells 400. The number of battery cells 400 can be set according to the size of the battery pack 10 and the voltage of the electrical equipment.

[0057] In some embodiments, reference Figure 1 The battery pack 10 may further include a connection row 800, which is used to connect the multiple battery cells 400 in series or in parallel so that the battery pack 10 reaches a corresponding operating voltage.

[0058] In some embodiments, a protective cover may be provided on the side of the bottom box away from the upper cover and / or on the side of the upper cover away from the bottom box. It is understandable that when the battery pack is installed with the first electrical device, the second output interface is in an empty state. To avoid leakage of the second output structure during use of the first electrical device, a protective cover may be provided on the side of the bottom box away from the upper cover to protect the second output interface and improve the stability of the battery pack. Similarly, when the battery pack is installed with the second electrical device, the first output interface is in an empty state. To avoid leakage of the first output interface during use of the second electrical device, a protective cover may be provided on the side of the upper cover away from the bottom box to protect the first output interface and improve the stability of the battery pack.

[0059] In the battery pack 10 provided in the embodiment of the present application, the shell 100 includes a bottom box 200 and an upper cover 300. The receiving space 101 surrounded by the bottom box 200 and the upper cover 300 can be used to accommodate the battery cell 400. The shell 100 can protect the battery cell 400 to prevent the battery cell 400 from being affected by environmental factors during use, thereby improving the stability of the battery pack 10. The upper cover 300 has a protruding portion 301 protruding in a direction away from the receiving space 101, and the first output interface 302 is arranged on the outer wall of the protruding portion 301, which is used to be electrically connected to the first electrical device. In this way, the battery pack 10 can match the first electrical device through the protruding portion 301 of the upper cover 300, thereby supplying power to the first electrical device; the bottom box 200 has a groove portion 201 recessed in a direction close to the receiving space 101, and the second output interface 202 is arranged on the inner wall of the groove portion 201, which is used to be electrically connected to the second electrical device. In this way, the battery pack 10 can also match the second electrical device through the groove portion 201 of the bottom box 200, thereby supplying power to the second electrical device. By respectively arranging the groove portion 201 and the protruding portion 301 on the bottom box 200 and the upper cover 300, the battery pack 10 can have output interfaces of different shapes to match different electrical devices respectively, thereby improving the compatibility of the battery pack 10.
