Embodiment Construction

[0053] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as Figure 1 to Figure 3 The battery pack 1 shown includes: a battery pack 10 and a battery case 20 , which are the main components of the battery pack 1 .

[0055] The battery pack 10 is an electric energy container for storing electric energy in the battery pack 1, which can store or output electric energy through mutual conversion of electric energy and chemical energy. Store and export electrical energy.

[0056] The battery core pack 10 stores electrical energy when being charged, and when the battery core pack 10 is connected to an electrical consumer such as an electric tool, it can provide the stored electrical energy to the electrical consumer.

[0057] The battery pack 10 may be an electric energy container as a whole, and the whole referred to here means that the substances used to realize the conversion of electr...

Abstract

The invention discloses a battery pack, which comprises: a battery casing; a battery core group, which is arranged in the battery casing; a circuit board, electrically connected with the battery core group; a connecting terminal, installed on the circuit board; wherein, the battery case The body includes: a mounting rail, capable of guiding the battery pack to be coupled to a charger or an electrical appliance at least along a first direction parallel to the length direction of the battery pack, and a housing groove, forming a depression at least in a direction perpendicular to the first direction, wherein A guide groove extending along the first direction is formed on the guide rail; in the first direction, the front end of the guide groove is open and the rear end is closed, and the connecting terminal is closer to the rear end of the guide groove. The battery pack of the present invention has a mounting guide rail structure capable of bearing relatively large weight and having a reasonable structure.

Description

technical field [0001] The invention relates to an electric energy storage device, in particular to a battery pack for power supply. Background technique [0002] As the power source of wireless power tools, battery packs have always been the main link restricting the development of wireless power tools. In the past, battery packs often only had an output voltage below 30V. When they were driving high-power power tools, they often caused insufficient power and battery life. bad question. There is still no battery pack with an output voltage exceeding 30V and a safe and reasonable structure, as well as a charger and an electric tool suitable for the battery pack. [0003] When the output voltage of the battery pack reaches 30V or more, its overall size and weight are considerably increased compared with the existing battery pack, and the existing installation structure of the battery pack combined with the charger or electrical appliance can no longer meet the requirements o...
