Abstract

A battery for electric tools, the housing of which has two box parts arranged separately on the left and right sides, the opposite faces of the two box parts each protrude inwardly to form a terminal seat, each of the terminal seats has a hook part opening and a plurality of electronic contacts, a handle part is connected to the two box parts, a trigger is arranged on the handle part, when the trigger is pressed, the hook parts that pass through the hook part openings can be retracted inwardly, and a battery module that is electrically connected to the plurality of electronic contacts is arranged in each of the two box parts; when the present application is combined with a double battery pack electric tool, the two terminal seats are inserted into the battery sockets on the left and right sides of the electric tool, and the hook parts are inserted into the insertion slots to be fixed, when it is necessary to remove the present application, only the trigger needs to be pressed, the handle part can be held by one hand, and the present application can be lifted from the electric tool, achieving the effect of quickly replacing the battery with one hand.

Claims

1. A power tool battery, comprising: An outer casing has two box sections on its left and right sides, each of which contains a battery compartment. An accommodating space is formed between the two box sections. A terminal block is protruding from the opposite side of each of the two box sections into the accommodating space. Each terminal block has a track, a hook opening communicating with the inside of the outer casing, and multiple electronic contacts. An outwardly extending handle is connected to the two box sections. The space inside the handle communicates with the two battery compartments. A trigger opening is formed on one side of the handle. A latch structure is provided inside the housing and includes a linkage mechanism, a trigger connected to one end of the linkage mechanism, and two hooks connected to the other end of the linkage mechanism. A return spring is provided between the latch structure and the housing. The trigger part protrudes from the trigger opening, and the two hooks extend out of their respective hook openings. When the trigger is pressed, the linkage mechanism is driven to retract the two hooks into the two hook openings. as well as Two battery modules are respectively disposed in each of the battery chambers and electrically connected to the plurality of electronic contacts of each of the terminal blocks.

2. The power tool battery as claimed in claim 1, wherein, A bridging portion is connected between the top sides of the two box portions. The space within the bridging portion communicates with the two battery compartments and the handle portion. Two pivot seats are provided on the left and right sides of the bridging portion, each of the two pivot seats having a transverse shaft hole. The linkage mechanism has a rotating shaft, two upper arms, and two lower arms. The rotating shaft is rotatably inserted through the two shaft holes. The two upper arms are connected to the rotating shaft and extend into the left and right sides of the handle portion. The trigger is connected between the ends of the two upper arms. The two lower arms are connected to the rotating shaft, and their ends each extend to the inner side of the opening of each hook. Each hook is connected to the end of each lower arm. The return spring is a torsion spring, which is sleeved on the rotating shaft and abuts against the outer shell and the linkage mechanism at both ends.

3. The power tool battery as described in claim 2, wherein, A bridging portion is connected to the top side of the two box portions. A neck recess is recessed forward in the middle of the rear of the bridging portion. The inner wall of the neck recess forms a groove extending in the vertical direction and forms an entrance at the rear. The left and right width of the accommodating space is greater than the left and right width of the space inside the neck recess. Two shoulders are formed on the bottom surface of the bridging portion adjacent to the left and right sides of the neck recess.

4. The power tool battery as described in claim 3, wherein, A movable fastener is attached between the left and right sides of the neck recess following the bridging portion, and the movable fastener spans the placement entrance.

5. The power tool battery according to any one of claims 1 to 4, wherein, The track of each terminal block is disposed on the front and rear sides of the terminal block and extends in the vertical direction. The hook opening is formed on the front side of each track. The bottom of each terminal block has multiple gates. An electronic contact base is attached to the inner side of each terminal block. The multiple electronic contacts are disposed on each electronic contact base and exposed outward from the multiple gates.

6. The power tool battery according to any one of claims 2 to 4, wherein, Each of the two box sections has a terminal block slot on its opposite side, and the two box sections and the bridging section have a front opening; each terminal block has a base plate around it, and each base plate is fixedly embedded in the terminal block slot; a front cover plate is combined with the front opening cover, and the handle section is divided into a front handle shell and a rear handle shell. The rear handle shell is connected to the two box sections, and the front handle shell is connected to the front cover plate and is aligned with the rear handle shell; a shell-shaped panel section is formed in the middle of the front cover plate.

7. The power tool battery as claimed in claim 6, wherein, The front of the panel has one or more light source holes, and a control circuit board is disposed inside the panel. The control circuit board is electrically connected to the two battery modules and the plurality of electronic contacts. One or more light sources are combined with the control circuit board, and each light source is disposed in its respective light source hole.

8. The power tool battery as claimed in claim 7, wherein, The front of the panel has a display window, and a power indicator is integrated with the control circuit board, with the power indicator protruding outward from the display window.
