The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0034] Please see Figures 1 to 7 This application provides a battery pack, which includes a housing 10, a locking device 40, a power display 50, and a Type-C interface 60. Specifically, the housing 10 houses a battery 20 and a circuit board 30, which are electrically connected. The locking device 40 is located on the housing 10 and is used to connect a power tool. The power display 50 is electrically connected to the circuit board 30 and is used to display the power level of the battery 20. The Type-C interface 60 is electrically connected to the circuit board 30. A display window 70 is provided on the housing 10 at the position corresponding to the power display 50. A connector 80 is provided on the housing 10 at the position corresponding to the Type-C interface 60.

[0035] Understandably, when the battery pack is charged, the power indicator 50 will be powered on and illuminate normally, providing real-time feedback to the operator through the display window 70. If the battery pack is depleted, the power indicator 50 will not illuminate. The operator can determine the battery pack's power level by observing the power indicator 50 and charge it promptly to ensure it always has sufficient charge. Furthermore, in addition to powering power tools, the battery pack can also power other electronic devices such as mobile phones and computers via its Type-C interface 60, expanding its functional applications.

[0036] Secondly, when charging the battery pack, it can also be charged using the Type-C interface 60, and the original charger of the battery pack can be used to charge the battery pack simultaneously, thereby improving charging efficiency.

[0037] Furthermore, the housing 10 has a top 11 and a bottom 12 arranged opposite to each other along its own height direction X, and a plurality of sides 13 located between the top 11 and the bottom 12. A display window 70 is provided on the top 11 / side 13, and a connector 80 is provided on the top 11 / side 13. When using the battery pack, the bottom 12 of the battery pack is usually held, so having the display window 70 and connector 80 on the top 11 or side 13 makes it easier to observe and use.

[0038] In one embodiment, along the height direction X of the housing 10, the battery 20 and the circuit board 30 are vertically distributed, with the circuit board 30 located above the battery 20. The power display 50 and the Type-C interface 60 are located on the side of the circuit board 30 near the top 11, while the display window 70 and the connector 80 are both located on the top 11. Thus, only the power display 50 and the Type-C interface 60 need to be added to the circuit board 30, and the corresponding display window 70 and connector 80 need to be added to the housing 10. There is no need to change the size and layout of a conventional battery pack; the overall structure is simple and easy to implement. Even battery packs of different models and specifications can be added, making modification difficult and highly versatile.

[0039] See Figure 7 In another embodiment, the interface 80 is located at the top 11, and the display window 70 is located at the side 13, extending along the height direction of the side 13. Compared to the top 11, the side 13 has a larger area, allowing the display window 70 to be positioned more prominently and easily observed.

[0040] Of course, this is not the only option. In other embodiments, the display window 70 and the interface 80 may both be located on the side 13, or the Type-C interface 60 may be located on the side 13 and the display window 70 may be located on the top 11. The specific configuration may be determined according to actual needs.

[0041] For example, multiple power indicators 50 are configured, and the number and position of display windows 70 correspond to the configuration of the power indicators 50. The power indicators 50 use light-emitting diodes (LEDs), with multiple LEDs spaced apart. The number of LEDs lit indicates the battery pack's power level. For example, all LEDs are lit when the battery is fully charged, and the number of lit LEDs gradually decreases as the power level decreases. The specific principle is prior art and will not be elaborated upon.

[0042] See Figure 7 When the display window 70 is located on the side 13, multiple light-emitting diodes are distributed at intervals along the height direction of the side 13, and the number and position of the display window 70 correspond to the configuration of the light-emitting diodes.

[0043] Of course, the power display 50 can also be a display screen. After the circuit board 30 detects the power status of the battery 20, it feeds back to the display screen and displays the remaining power in digital form.

[0044] The battery pack also includes an indicator switch 90. The indicator switch 90 is electrically connected to the circuit board 30 and is used to control the on / off state of the power display 50. When the power level needs to be checked, the indicator switch 90 is pressed, causing the power display 50 to light up. Thus, when the battery level is not needed, the power display 50 is off, preventing the power display 50 from consuming power from the battery 20 for extended periods and reducing the energy loss of the battery 20.

[0045] Furthermore, a pressing part 14 is provided on the housing 10 corresponding to the display switch 90, and the pressing part 14 is positioned close to the display window 70. In this way, pressure is applied to the pressing part 14 to control the opening or closing of the display switch 90, and the close positioning of the display window 70 and the pressing part 14 facilitates observation by the operator.

[0046] For example, the display switch 90 is a push-button switch. The pressing part 14 is a pressure block connected to the housing 10 on one side, and the pressure block can swing up and down relative to the connection point. When the pressing part 14 is subjected to a downward pressing force, the pressure block swings downward relative to the connection point and presses onto the display switch 90, turning on the display switch 90 and energizing the power display 50. After the external force is removed, the pressure block swings upward relative to the connection point to reset, releasing the pressure on the display switch 90, turning off the display switch 90, and de-energizing the power display 50.

[0047] In one embodiment, the housing 10 includes a body 15 and a cover 16. Along the height direction X of the housing 10, the body 15 and the cover 16 are vertically distributed, with the cover 16 located above the body 15 and detachably connected to it. The cover 16 and the interior of the body 15 together form a battery compartment 17, within which the battery 20 and circuit board 30 are disposed. This simplifies the installation of the battery 20 and circuit board 30.

[0048] In this embodiment, the top 11 is configured as the top wall of the hatch 16. The structure provided on the top 11 can be integrally formed during the processing of the hatch 16.

[0049] For example, a protrusion 151 is provided on the outer wall of the cabin 15 near the end of the hatch 16, and a slot 161 is provided on the side wall of the hatch 16 near the end of the cabin 15. When the hatch 16 is fitted onto the cabin 15, the protrusion 151 can be inserted into the slot 161, thereby realizing a detachable connection between the hatch 16 and the cabin 15.

[0050] Furthermore, the top wall of the hatch 16 is provided with a groove 18, which is recessed towards the battery compartment 17. The pressing part 14 and the display window 70 are located within the groove 18. Meanwhile, along the height direction X of the housing 10, the height of the pressing part 14 is lower than the height of the top wall of the hatch 16.

[0051] Understandably, the pressing part 14 is located within the recess 18 and its height is lower than the top wall of the cover 16. During use, it is less likely to be accidentally pressed, thus preventing the power indicator 50 from lighting up due to accidental contact and further reducing the power consumption of the battery 20.

[0052] The shell 10 also includes a base 19, which is detachably connected to the lower part of the hull 15, and a locking device 40 is provided on the base 19. Further, the bottom 12 is configured as the bottom wall of the base 19, and the side 13 is configured to be jointly formed by the side wall of the hull 15 and the side wall of the hatch 16.

[0053] For example, the inner wall of the base 19 is provided with an inverted buckle 191, and the lower outer wall of the cabin 15 is provided with a slot 152. When the base 19 is sleeved onto the lower part of the cabin 15, the inverted buckle 191 is inserted into the slot 152, thereby realizing the detachable connection between the cabin 15 and the base 19.

[0054] Furthermore, the locking device 40 is configured as an elastic piece 41 connected to the base 19 and a hook 42 provided on the elastic piece 41. The power tool has a slot for the hook 42 to engage. Preferably, the elastic piece 41 is integrally formed with the base 19. The base 19 has vertical slots 43 corresponding to the two sides of the elastic piece 41. This allows the elastic piece 41 to swing relative to the connection point between the two, and pressing the elastic piece 41 causes the hook 42 to disengage from the slot.

[0055] See Figure 5 The connector 80 has a step 81. The step 81 extends from the inner wall of the connector 80 toward the bottom 12. One end of the Type-C interface 60 is fixed to the circuit board 30, and the other end extends to the step 81 and is inserted into the step 81.

[0056] In this way, step 81 can limit the Type-C interface 60, prevent the Type-C interface 60 from shaking relative to the circuit board 30, ensure a stable connection between the Type-C interface 60 and the circuit board 30, and reduce the failure rate.

[0057] Furthermore, along the height direction X of the housing 10, the distance between the top surface of the Type-C interface 60 and the top 11 is H. In this embodiment, H satisfies the following relationship: H ≥ 1 mm. This protects the Type-C interface 60 from damage.

[0058] Preferably, the value of H is 1mm-2mm, and the specific value can be 1mm, 1.3mm, 1.5mm, 1.8mm, 2mm, etc. The specific value can be selected according to actual needs and is not limited here.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
