Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] In the accompanying drawings, 1 is a battery, 2 is a casing, 3 is an electric tool, and 4 is a switch.

[0015] figure 1 with figure 2 The structure of the present invention is shown. As shown in the figure, the battery pack is composed of a battery (1), a power cord, a spring and a switch (4) arranged inside the shell (2), and is the main component of the battery pack. The main battery pack is connected to the electric tool (3) Below is the common power supply, with loading and unloading switches, which can be used to install and disassemble the battery. The secondary battery pack is an external power supply, which is a backup power supply. Among them, there are more than one battery pack in the battery pack, which can be paired and switched. . The positive pole of the battery (1) is connected to the elastic switch (4) below through the power cord. The f...

Abstract

The invention provides a battery pack for an electric tool. The battery pack comprises batteries, shells, switches, springs and sliding grooves. The battery pack is formed by arranging the batteries, power lines, the springs and the switches in the shells. Positive electrodes of the batteries are connected with the lower elastic switches through the power lines and then connected with a motor through the bidirectional switch and a main switch of the motor. The sliding grooves or slots are formed in the lower portions of the shells of the battery pack and are internally connected with power source contact chips and the springs. An elastic lock is arranged on one side of each shell. The battery pack has the advantages that the mode of the sliding grooves and the slots is adopted so that an auxiliary battery pack body can be quickly connected to a main battery pack body, power sources can be used without interruption, the power source contact chips of the two battery pack bodies can be protected, and electricity leakage and short circuits caused by exposure can be avoided; the power sources can be switched without interruption through the bidirectional switch; connection of the battery with full electricity and the battery with the electricity used up can be cut off quickly through the elastic switches; integrally, the electric tool can use the power sources without interruption, and the service life of the batteries is protected.

Description

technical field [0001] The invention relates to a detachable, installed and sustainable electric tool battery pack with a switch installed on the battery pack and the bottom of the battery pack. Suitable for hand-held power tools. Background technique [0002] At present, the service life of the batteries in the battery packs of known hand-held electric tools is relatively short, and it is inconvenient to stop working when replacing the batteries. The patent No. CN201210572150.0 is a snap-on battery pack and a snap-on battery pack in an electric tool. It provides a sliding battery pack and an electric tool using the sliding battery pack. The sliding battery pack includes a plurality of batteries A plurality of battery packs are electrically connected, and each of the plurality of battery packs includes two adjacent sides, and two adjacent battery packs can slide along the two adjacent sides . In this way, the sliding battery pack can have different shapes. When the slidin...
