Description

Technical Field

[0001] This utility model belongs to the field of power tools, and specifically relates to an improved battery pack for power tools. Background Technology

[0002] Power tools, such as sweepers, hair dryers, and pruning machines, are commonly used equipment in daily life and work. Conventional handheld power tools generally include a handle, a linkage, and a functional section. The functional section is equipped with a working unit that is used for operation after being powered on.

[0003] Most existing power tools use battery packs for power, and the battery packs are detachably mounted to the battery mounting positions on the power tool. Generally, the battery pack has a locking mechanism for locking after assembly, and also has a corresponding operating unit for unlocking and removing the battery pack.

[0004] The battery pack itself is equipped with a handle structure for easy carrying. If the handle structure and the fastening structure can be linked, the operation unit can be eliminated and the operation will be more convenient. This application has made further design and improvement in this direction. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides an improved power tool battery pack, wherein the handle structure and the fastening structure are linked, and the fastening structure can be unlocked when the handle is lifted to remove the battery pack, making operation convenient.

[0006] The present invention is solved by the following technical solution.

[0007] An improved power tool battery pack includes a battery pack body with a flip-up handle and a linkage component on the handle. The battery pack body also has an extendable fastening structure located at one end of a bending and rotating component, the other end of which is a linkage end. The linkage component acts on this linkage end to retract the fastening structure. An elastic component is provided on the inner side of the bending and rotating component to keep the fastening structure extended.

[0008] In this application, the battery pack allows for convenient disassembly and removal through the linkage between the handle, the bending and rotating component, and the locking structure, eliminating the need for an additional unlocking unit. Specifically, after inserting the battery pack into the mounting position on the power tool, the elastic force of the spring element causes the locking structure to extend and lock, while the handle rotates to a flat position. To remove the battery pack, the handle is flipped up, causing the linkage component along with the handle to rotate synchronously. This linkage component drives the bending and rotating component to rotate, retracting the locking structure and releasing the locking state, allowing the battery pack to be easily removed.

[0009] In a preferred embodiment, the two ends of the handle are rotatably mounted on the battery pack body via handle shafts, and a linkage is provided between the two handle shafts, resulting in a compact overall structure and high sturdiness after assembly.

[0010] In a preferred embodiment, the bending and rotating component is provided with an assembly shaft, which is mounted on an assembly seat on a plate in the battery pack body. The bending and rotating component can rotate at a small angle around the assembly shaft to meet the requirements of the fastening and unlocking states.

[0011] In a preferred embodiment, the elastic element is a spring, which is disposed between the bending and rotating element and the plate to provide elastic force.

[0012] In a preferred embodiment, the handle is located on one side of the battery pack body, the fastening structure is located on the adjacent other side, and the bending and rotating component is located inside these two sides, resulting in a compact overall structure and convenient linkage operation.

[0013] Compared with the prior art, the present invention has the following advantages: it provides an improved power tool battery pack in which the handle structure and the fastening structure are linked, so that the fastening structure can be unlocked when the handle is lifted and the battery pack can be taken out, which is convenient to operate.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] See Figures 1 to 5 This utility model relates to an improved power tool battery pack, comprising a battery pack body 1, a flip-up handle 2 on the battery pack body 1, and a linkage 22 on the handle 2; the battery pack body 1 also has an extendable fastening structure 3, which is located at one end of a bending and rotating member 33, and the other end of the bending and rotating member 33 is a linkage end 35, on which the linkage 22 can act to retract the fastening structure 3; the inner side of the bending and rotating member 33 is provided with an elastic member 6 to keep the fastening structure 3 in an extended state.

[0023] Specifically, as shown in the accompanying drawings, in this application, the two ends of the handle 2 are rotatably mounted on the battery pack body 1 via handle pivots 21. A linkage 22 is provided between the two handle pivots 21, resulting in a compact overall structure and high assembly stability. The bending and rotating component 33 is provided with an assembly pivot 31, which is mounted on an assembly seat on the plate 13 in the battery pack body 1. The bending and rotating component 33 can rotate at a small angle around the assembly pivot 31 as its axis, satisfying the requirements of the locking and unlocking states.

[0024] In this application, the elastic element 6 is a spring, which is disposed between the bending and rotating element 33 and the plate 13 to provide elastic force. Furthermore, in this application, the handle 2 is disposed on one side of the battery pack body 1, the fastening structure 3 is disposed on the adjacent other side, and the bending and rotating element 33 is disposed inside these two sides, resulting in a compact overall structure and convenient linkage operation.

[0025] As can be seen from the above description, the battery pack in this application allows for convenient disassembly and removal through the linkage between the handle 2, the bending and rotating component 33, and the fastening structure 3, without the need for an additional unlocking unit. Specifically, after the battery pack is inserted into the mounting position on the power tool, the elastic force of the elastic component 6 causes the fastening structure 3 to extend and lock, while the handle 2 rotates to a flat position. When it is necessary to remove the battery pack, the handle 2 is flipped up. At this time, the linkage component 22, which is together with the handle 2, rotates synchronously. The linkage component 22 drives the bending and rotating component 33 to rotate, causing the fastening structure 3 to retract, releasing the fastening state, and the battery pack can be easily removed.

[0026] As described above, this utility model provides an improved power tool battery pack, wherein the handle structure and the fastening structure are linked, and the fastening structure can be unlocked when the handle is lifted to remove the battery pack, making operation convenient.
