Description

Battery pack [ Field of technology ] The present utility model relates to a battery pack, and more particularly, to a battery pack for a cordless tool. [ Background Art ] In many existing cordless power tools and other cordless devices, a battery pack is typically selected as the power source for ease of movement and portability. Nowadays, the battery pack is widely applied to electric tools such as electric drills, electric hammers, electric picks, angle grinders, blowers, grass cutters, lawn mowers, electric shears and other electric equipment, lighting lamps, sound equipment, outdoor power supplies and other electric equipment, and is popular among masses. In order to solve the problem that the chute is easy to damage, a reinforcing piece is usually added at the chute of the battery pack for increasing wear resistance and structural strength, but because of poor placement and/or poor positioning of the reinforcing piece during injection molding, glue overflow often occurs at the joint of the reinforcing piece and the battery pack end cover, or the phenomenon that a sliding block of an injection mold collides with the reinforcing piece occurs. In view of the foregoing, it is desirable to provide an improved battery pack that overcomes the shortcomings of the prior art. [ Invention ] Aiming at the defects of the prior art, the utility model aims to provide a battery pack with small weight and good positioning effect. The battery pack is adapted to an electric tool to provide power, the battery pack comprises a shell, a battery pack mounted on the shell and a plug-in portion formed on the upper end face of the shell, the plug-in portion is connected to the electric tool along a plug-in direction to transmit the power of the battery pack, the plug-in portion is provided with a plug-in block protruding upwards from the shell, a sliding rail protruding outwards from the plug-in block, a reinforcing piece mounted on the plug-in block and a positioning hole penetrating through the sliding rail along a vertical direction perpendicular to the plug-in direction, the positioning hole is arranged in the sliding rail at intervals, and the sliding rail is provided with a notch which is communicated with the positioning hole. The reinforcement has the first reinforcement part connected to the lower end face of the sliding rail, the second reinforcement part connected to the side wall of the plug block and the third reinforcement part connected to the upper end face of the shell, wherein the first reinforcement part is parallel to the third reinforcement part, and the second reinforcement part is perpendicular to the first reinforcement part. A further improvement is that the first reinforcing portion is exposed to the notch. The plug-in part is also provided with a containing groove formed between the sliding rail and the upper end face of the shell, and the second reinforcing part is abutted against the side wall of the containing groove. A further development is that the third reinforcement part is embedded in the interior of the housing. A further refinement is that the stiffener has a spacing hole through the third stiffener portion, the spacing hole configured to locate the third stiffener portion. The notch is provided with a step wall parallel to the second reinforcing part and a guide wall connected with the step wall, and the extending direction of the guide wall is intersected with the extending direction of the step wall. The further improvement scheme is that the included angle between the extending direction of the guide wall and the extending direction of the step wall is 100-140 degrees. A further development provides that the first reinforcement part is located below the guide wall. A further development provides that the guide wall is connected between the step wall and the first reinforcement portion. Compared with the prior art, the utility model has the following beneficial effects that the positioning holes are arranged in the sliding rail at intervals, and the notch communicated with the positioning holes is arranged on the sliding rail, so that the weight of the sliding rail is reduced, and the sliding rail is used for positioning the reinforcing piece.
