Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, the present invention discloses an electric tool 100, which includes a housing 10, a working mechanism 20 mounted on the housing 10, and a battery assembly 30. In the present embodiment, the working mechanism 20 is a chain saw, but in other embodiments, the working mechanism 20 may be a reciprocating saw, a suction blower, or the like. The present invention is not limited to the specific structure of the working mechanism 20.

Referring to fig. 2 and 3, the housing 10 includes a front end 11 and a rear end 12. A housing chamber (not shown) is provided in the front end 11 to house a driving mechanism (not shown) for driving the working mechanism 20. The working mechanism 20 is mounted on the drive mechanism. The rear end 12 is provided with a receiving groove 121 for receiving the battery assembly 30 and a first fixing member 122. The receiving groove 121 is formed by being recessed from the top of the rear end 12, that is: the accommodating groove 121 is configured such that when the power tool 100 is placed on a horizontal plane, an included angle between the accommodating groove 121 and the horizontal plane is an acute angle. With this arrangement, when the battery assembly 30 is inserted into the receiving groove 121 along the direction AA shown in fig. 3, the battery assembly 30 can slide into the receiving groove 121 along the inner wall of the receiving groove 121, so as to reduce the force applied by the user and reduce the impact of the battery assembly 30 on the housing 10 during installation. The receiving groove 121 is further provided with a vent 1211 communicating with the outside to facilitate heat dissipation of the battery assembly 30. Referring to fig. 2 and 1, the cross-section of the receiving groove 121 in the insertion direction (i.e., AA direction shown in fig. 3) of the battery assembly 30 is rectangular, the long side of the rectangle is disposed substantially along the front-back direction, and the short side of the rectangle is disposed along the lateral direction (i.e., the left-right direction shown in fig. 1). Since the receiving groove 121 is provided obliquely and the short side of the rectangle is provided in the left-right direction, the length and width of the housing of the electric power tool 100 can be reduced. In this embodiment, the first fixing element 122 is a slot formed by recessing the inner wall of the receiving slot 122. However, it is understood that the specific structure of the first fixing member 122, the specific position on the housing 10, has various embodiments. For example, the first fixing member 122 may be disposed on a top wall of the rear end 12 to facilitate one-handed operation of a user for replacing a battery. The first fixing member 122 may be a snap. The present invention is not limited to the structure of the first fixing member 122. The rear end 12 is also provided with a hook 123 to allow a user to hang the power tool 100 on another device or to fasten the power tool to the waist.

Referring to fig. 2 and 3, the housing 10 is further provided with a main handle 13 at the top wall and an auxiliary handle 14 at the side wall. The main handle 13 is located between the front end 11 and the rear end 12. A control panel 131 is disposed on the upper portion of one end of the main handle 13 close to the working mechanism 20. The control panel 131 is provided with a power switch and a fault indicator lamp. In use, the user can determine the type of fault of the power tool 100 according to the color, the number of blinks, and the like of the fault indicator light. The side of the main handle 13 facing the housing 10 is provided with a trigger switch 132, and the side thereof facing away from the housing 10 is provided with a trigger switch self-locking piece 133.

Referring to fig. 1 and 3, the battery assembly 30 is inserted into the receiving groove 121 along the direction AA and partially protrudes out of the receiving groove 121. With such an arrangement, not only is it convenient for a user to install the battery assembly 30, but also the heat dissipation of the battery assembly 30 can be facilitated, thereby improving the heat dissipation performance of the battery assembly 30. Referring to fig. 4 and fig. 5, the battery assembly 30 includes a battery cell 31, a battery case 32 for accommodating the battery cell 31, and a second fixing member 33. The battery case 32 is provided with a first slot 321 and a second slot 322. The second fixing member 33 is matched with the first fixing member 122 to fix the battery assembly 30 in the receiving groove 121. The second fixing member 33 includes an elastic element 331 mounted on the battery cell 31, and a substrate 332 mounted on the elastic element 331. In this embodiment, the elastic element 331 is a spring. However, it is understood that the elastic element 331 has various embodiments, such as: the elastic element 331 may also be an elastic plastic. One end of the base plate 332 is provided with a clamping arm 3321 matched with the clamping groove, and the other end of the base plate is provided with a pressing arm 3322. Referring to fig. 6 in combination with fig. 4 and 5, when the pressing arm 3322 is pressed, the elastic element 331 is elastically deformed by the base plate 332, at this time, the pressing arm 3322 at least partially enters the second slot 322, the retaining arm 3321 at least partially enters the first slot 321, the retaining arm 3321 is separated from the card slot, and at this time, the battery assembly 30 can slide along the AA direction. When the pressing arm 3322 is released, the base plate 332 is reset under the action of the elastic element 331, the pressing arm 3322 is separated from the second slot 322, the retaining arm 3321 is separated from the first slot 321, the retaining arm 3321 abuts against the slot, and the battery assembly 30 is fixed in the accommodating slot 121.

Compared with the prior art, the electric tool 100 of the present invention has the inclined accommodating groove 121, so that the battery assembly 30 is easy to install; moreover, the battery assembly 30 partially protrudes out of the receiving groove 121, so that the heat dissipation performance of the battery assembly 30 is high.

The above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.
