Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a battery pack adapter for power tools. Background Technology

[0002] Currently, power tools (such as electric drills, angle grinders, and electric hammers) are typically powered by detachable battery packs to improve usage flexibility, as exemplified by the power tool proposed in Chinese Patent Publication No. CN222494136U. However, the interface specifications between power tools and battery packs from different brands or models are not standardized, making it impossible for users to use them across platforms. This necessitates the purchase of a compatible battery pack for each power tool, thereby increasing usage costs.

[0003] To address this issue, this utility model proposes a battery pack adapter for power tools. Utility Model Content

[0027] Example 1:

[0028] like Figures 1 to 7 As shown, the battery pack adapter for the power tool of this application includes a power tool 1, a battery pack 2, and an adapter mechanism 3.

[0029] Furthermore, the power tool 1 has a battery slot at its bottom.

[0030] Furthermore, such as Figures 3 to 7 As shown, the adapter 3 is located between the power tool 1 and the battery pack 2, with its top detachably connected to the power tool 1 and its bottom detachably connected to the battery pack 2.

[0031] The transfer mechanism 3 includes:

[0032] An upper shell 31 and a lower shell 32 detachably connected thereto, wherein the upper shell 31 and the lower shell 32 are detachably connected by screws;

[0033] Locking element 33 is used to lock the adapter 3 and the power tool 1;

[0034] The first spring 34 is located inside the lower housing 32 and provides a resetting force for the locking member 33;

[0035] Resistance component 35 is used to increase the pressing force of the locking member 33.

[0036] Specifically, the upper shell 31 has a first communicating groove that penetrates its interior;

[0037] The upper shell 31 has a second communicating groove that penetrates its interior at the top edge, and connecting holes are provided at both ends of the communicating groove.

[0038] The bottom of the lower shell 32 is provided with a lower mold interface 3201 for matching battery packs 2 of different specifications. The lower mold interface 3201 provides an insertion state. When viewed from the front, the battery pack 2 is inserted into the lower mold interface 3201 from left to right.

[0039] The locking element 33 includes:

[0040] The latching part 3301 is in sliding fit with the first communicating groove, and the adapter mechanism 3 is detachably connected to the battery slot through the latching part 3301.

[0041] The pressing part 3302 is used to provide a pressing position, and hemispherical grooves are provided on both ends of the pressing part 3302;

[0042] The locking component 33 also includes a connecting block 3303 for connecting the locking block and the pressing part 3302. The bottom of the connecting block 3303 is fixedly provided with a positioning block 3304 for positioning the first spring 34. The buckle part 3301, the pressing part 3302, and the connecting block 3303 are integral injection molded parts.

[0043] The resistance component 35 includes a second spring 3501 and a locking ball 3502 fixedly connected thereto. The locking ball 3502 is used to engage with the hemispherical groove. The second spring 3501 is disposed in the connecting hole, and the locking ball 3502 is in sliding engagement with the connecting hole.

[0044] With the resistance component 35 in place, when the adapter mechanism 3 is removed from the power tool 1, a downward pressing force is first required on the pressing part 3302. When the pressing part 3302 is pressed, the pressing part 3302 moves downward and squeezes the first spring 34. At the same time, the hemispherical groove on the pressing part 3302 applies a radial force to the locking ball 3502, driving the locking ball 3502 to move into the connecting hole and squeeze the second spring 3501. As the pressing part 3302 is pressed downward, it is simultaneously subjected to the forces of the first spring 34 and the second spring 3501. This results in a greater pressing force being required to drive the pressing part 3302, thus preventing accidental opening due to accidental contact.

[0045] Example 2:

[0046] The present application discloses a battery pack adapter for power tools, which includes a power tool 1, a battery pack 2, and an adapter mechanism 3.

[0047] Furthermore, the power tool 1 has a battery slot at its bottom.

[0048] Furthermore, the adapter 3 is located between the power tool 1 and the battery pack 2, with its top detachably connected to the power tool 1 and its bottom detachably connected to the battery pack 2.

[0049] The transfer mechanism 3 includes:

[0050] Upper shell 31 and lower shell 32 detachably connected thereto;

[0051] Locking element 33 is used to lock the adapter 3 and the power tool 1;

[0052] The first spring 34 is located inside the lower housing 32 and provides a resetting force for the locking member 33;

[0053] Resistance component 35 is used to increase the pressing force of the locking member 33.

[0054] Specifically, the upper shell 31 has a first communicating groove that penetrates its interior;

[0055] The upper shell 31 has a second communicating groove that penetrates its interior at the top edge, and connecting holes are provided at both ends of the communicating groove.

[0056] like Figure 8 As shown, the bottom of the lower shell 32 is provided with a lower mold interface 3201 for matching battery packs 2 of different specifications. The lower mold interface 3201 provides another insertion state. When viewed from the front, the battery pack 2 is inserted into the lower mold interface 3201 from right to left.

[0057] The first and second embodiments combine to provide a changeable insertion direction adapter 3, which is convenient for staff to choose adaptively.
