Description

Technical Field

[0001] The utility model belongs to the technical field of electric tool batteries, and in particular relates to a battery assembly structure for electric tools. Background Art

[0002] With the widespread use of power tools (such as blowers, vacuums, and pruners) for home maintenance, portability and ease of use have become important considerations for users. To meet the needs of long-term work, many power tools use dual-battery designs to extend operating time. However, existing power tool designs with dual battery packs have some significant issues:

[0003] 1. Improper installation position: Most dual-battery power tools currently on the market typically have their two battery packs mounted symmetrically or side by side on the sides of the handle. For example, the battery assembly scheme disclosed in the utility model patent for a blower / suction blower, with authorization publication number CN213628063U. While this layout is simple and straightforward, it takes up a significant amount of lateral space, making the handle of the entire tool excessively wide. This not only affects the user's grip comfort but also increases the overall size of the tool, making it difficult to store and carry.

[0004] 2. The disassembly and assembly process is complicated: When replacing the battery, the entire battery pack including the two battery packs needs to be removed from the side of the handle and then reinstalled. This process often takes a long time.

[0005] 3. Impact on operating experience: When the battery packs are installed on both sides of the handle, they may hinder the user's hand movements, especially when performing delicate tasks. The extra protruding parts may affect the line of sight or interfere with the operation of other objects, reducing work efficiency and increasing the risk of misoperation.

[0006] 4. Poor center of gravity distribution: Due to the heavy weight of the battery, if it is placed at a higher position on the handle (such as on the side), the center of gravity of the entire tool will be too high, which will affect the user's perception of the tool's stability during operation and easily cause arm fatigue after long-term use.

[0007] In summary, the aforementioned issues in the existing technology limit further improvements in the performance of dual-battery power tools. Therefore, it is crucial to develop a novel battery assembly solution that ensures adequate power supply while optimizing the handle structure and enhancing the user experience. It is against this backdrop that this present invention proposes an innovative solution, aiming to overcome the shortcomings of the existing technology and provide a more user-friendly, efficient, and practical product. Utility Model Content

[0008] In order to solve the above technical problems, the present invention solves them through the following technical solutions.

[0009] A battery assembly structure for an electric tool is located on the handle of the electric tool. The handle includes a grip portion and a hand guard portion. The hand guard portion is located directly below the grip portion. The battery assembly structure includes two battery packs. The two battery packs are assembled on the downward-facing surface of the hand guard portion in an eight-shaped manner with a front-to-back distribution.

[0010] As a preferred embodiment of the present application, two battery packs are assembled relative to each other, and the battery packs are connected to the handle by plugging and unplugging.

[0026] A battery assembly structure for a power tool is located on the power tool's handle. The handle comprises a grip portion 100 and a hand guard 200, with the hand guard 200 positioned directly below the grip portion 100. The battery assembly structure includes two battery packs 300, which are mounted on the downward-facing surface of the hand guard 200 in a figure-eight arrangement, arranged front-to-back. This design not only fully utilizes the power tool's handle space but also maintains the tool's overall balance, preventing the handle from being top-heavy and bottom-light, which would affect the tool's handling. Furthermore, the front-to-back distribution helps distribute weight, reducing operator fatigue, and significantly reduces the handle's lateral dimensions, saving packaging space.

[0027] To facilitate replacement of the battery packs 300, two battery packs 300 are mounted opposite each other and connected to the handle via plug-and-unplug technology. This design prevents interference between the battery packs 300 during insertion and removal, preventing one battery pack 300 from blocking another. This allows users to quickly and easily replace the battery packs 300 without the need for additional tools or disassembly of the entire device, significantly improving work efficiency and simplifying maintenance.

[0028] As an embodiment of this application, refer to Figure 1The hand guard 200 is equipped with a partition block 210 at the bottom, with mounting slots for the battery pack 300 on either side. This structural arrangement ensures that the battery is securely fixed in place, preventing it from loosening or falling due to vibration. Furthermore, the battery pack 300's center of gravity is located at the bottom of the hand guard 200, resulting in a low and rearward center of gravity, making it suitable for power tools with heavy working parts located at the front of the handle, such as lawn mowers and pruners.

[0029] As another embodiment of the present application, refer to Figure 2 The front end of the hand guard 200 extends toward the front end of the handle and is provided with a mounting block 220. The mounting block 220 is symmetrically provided with mounting slots for mounting the battery pack 300. The overall layout is more compact and reasonable, and the overall center of gravity is moved forward and upward compared to the previous embodiment, making it suitable for power tools with lightweight working parts, such as blowers and vacuums.

[0030] Taking into account the varying demands for grip comfort among different users, the grip portion 100 of the handle is ergonomically designed. Its surface is covered with a soft, friction-resistant material, ensuring a pleasant feel even after prolonged use. Furthermore, depending on the specific application scenario, the hand guard 200 can optionally be equipped with additional protective features, such as rubber pads or metal mesh, to enhance its durability and safety.

[0031] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
