Description

Lithium battery pack convenient for replacement and maintenance of fuse

Technical Field

The utility model relates to a lithium cell technical field specifically is a make things convenient for fuse to change lithium cell group of maintaining.

Background

The lithium battery is a novel energy source and has the advantages of large capacity, high energy density, greenness and no pollution compared with a lead-acid battery. The method is widely applied to various fields at present. But in some devices or electric vehicles. The lithium battery pack may be placed inside the device along with other tools. At present, a charging and discharging port of a lithium battery pack is fixed on a chassis shell by using a connector. Although the battery pack is in a short-circuited fuse that protects the circuit from overload, such protection devices are present inside the battery pack case. If the fuse of the battery pack needs maintenance or replacement, the battery pack needs to be lifted out of the equipment and then can be replaced after the upper cover of the battery pack case is opened.

The fuse acts as the most effective protection device for a circuit failure. Frequent maintenance is required. And the number of replacements is also large. But it is inside the battery pack. Replacement requires opening the battery chassis. This is time consuming and labor intensive because the inside of the battery pack is a delicate and exposed circuit. Not only is the circuit broken easily, but also the danger of electric shock is given to the operator.

An object of the utility model is to provide a make things convenient for fuse to change lithium cell group of maintaining to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a make things convenient for lithium cell group that fuse was changed and was maintained, includes upper cover, inferior valve and group battery, the casing is constituteed to upper cover and inferior valve, and the group battery is installed in the inside of casing, and a side of casing is equipped with electric quantity display meter, air switch and fuse, and the hole that air switch's button switch department seted up on through the casing is exposed externally, and electric quantity display meter, air switch and fuse all are connected with the group battery, and the outside of casing is equipped with the connector, and the group battery is connected through the wire to the connector.

As a further aspect of the present invention: and fixed handles are arranged on two sides of the shell.

As a further aspect of the present invention: the outside of fuse is equipped with the fuse apron.

As a further aspect of the present invention: the fixed handle is made of metal.

As a further aspect of the present invention: the model of the air switch is 2P-125.

As a further aspect of the present invention: the upper cover and the lower shell are connected in a separable mode.

As a further aspect of the present invention: the fuse cover plate is fixed through screws.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can be under the condition of not opening group battery upper cover. The power supply is turned off. At the service opening. And directly carrying out maintenance and replacement. The existing battery pack is solved. When the fuse is replaced. And hoisting the battery pack. The battery pack upper cover is opened to replace the battery pack.
