Problems solved by technology

[0002] As the power source of portable electric tools, battery packs have always been the main link restricting the development of portable electric tools. In the past, the output voltage of battery packs was low. When driving high-power electric tools, it would cause insufficient power and poor battery life.
[0003] However, by increasing the number of cells and increasing the output voltage of the battery pack, its size and weight will increase accordingly, which will affect the comfort of the user and make it difficult for the user to use power tools flexibly.
And the increase in the number of cells will lead to an increase in internal heat when the battery pack is charged and discharged.

Embodiment Construction

[0042] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0043] refer to figure 1 As shown, the wearable battery pack 100 includes: a battery pack body 10 and a wearable device 20 . The battery pack body 10 is used to provide a power source for the power tool, and the wearable device 20 is worn by the user so that the user can carry the battery pack body 10 on the back of the user through the wearable device, so as to facilitate the user to operate the power tool.

[0044] For the convenience of description, as shown in Figure 2, the definitions of "up", "down", "above", "below", "left", "right" and so on instruct the user to place the battery pack The orientation of the main body 10 when worn on the user's back, where the side close to the user's back is defined as the front, and the side away from the user's back is defined as the rear.

[0045] The battery pack body 10 includes an electric...

Abstract

The invention discloses a wearable battery pack, which comprises: a battery pack body, wherein the battery pack body comprises battery cores and a shell for accommodating the battery core; and a wearing device for being wore by a user so as to carry the battery pack on the back of the user, wherein the battery pack body further comprises a heat dissipation channel penetrating through the battery pack body from one side to the opposite side, and the heat dissipation channel penetrating side of the batter pack body is positioned between the back of the user and the other side when the user carries the battery pack body. The invention provides the wearable battery pack capable of being carried by the user, wherein the battery pack has good heat dissipation performance and can be comfortably carried by the user.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a wearable battery pack. Background technique [0002] As the power source of portable electric tools, battery packs have always been the main link restricting the development of portable electric tools. In the past, the output voltage of battery packs was low. When driving high-power electric tools, it would cause insufficient power and poor battery life. [0003] However, by increasing the number of cells and increasing the output voltage of the battery pack, its dimensions and weight will increase accordingly, which will affect the comfort of the user and make it difficult for the user to use power tools flexibly. And the increase in the number of cells will lead to an increase in internal heat when the battery pack is charged and discharged. [0004] Therefore, it is necessary to design a wearable battery pack with good heat dissipation performance that can be comforta...
