Description

Low-voltage lithium battery with charging protection

Technical Field

The utility model relates to the technical field related to batteries, in particular to a low-voltage lithium battery with charging protection.

Background

Lithium batteries are now a common device. The lithium cell of integrated combination can charge for equipment as an independent electrical apparatus, and the drive device work can look over the electric quantity from equipment when lithium cell and equipment are connected, but the electric quantity can not be seen after most lithium cells are dismantled from equipment, brings inconvenience for using and charging.

SUMMERY OF THE UTILITY MODEL

The utility model provides a low-voltage lithium battery with charging protection, which can display electric quantity, and aims to overcome the defect that a detached lithium battery in the prior art does not display electric quantity.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a low pressure lithium cell of protection that charges in area, includes shell, group battery and controller are installed in the shell, group battery and controller electricity are connected, embedded installing in the shell roof outside charges mouthful and display screen, the mouth that charges passes through the controller and is connected with the group battery electricity, the display screen passes through the controller and is connected with the group battery electricity.

The external power source is connected to the charging port and the battery pack is charged through the controller, the battery pack displays the electric quantity on the display screen through the controller, and when the lithium battery driving device is used, the lithium battery cannot completely consume the electric quantity of the lithium battery, so that the electric quantity can be displayed while the power is supplied to the display screen even if the detached lithium battery is detached, and the purpose of displaying the electric quantity is achieved.

Preferably, a charging switch is installed on the outer side of the top wall of the housing, and the charging port is electrically connected with the controller through the charging switch. Only when the charging switch is turned on, the charging can be carried out through the charging port, and the charging safety is guaranteed.

Preferably, a display switch is installed on the outer side of the top wall of the shell, and the display screen is electrically connected with the controller through the display switch. When not pressing down the display switch, the display screen does not work and does not show the electric quantity, avoids showing the electric quantity all the time and causes the waste.

Preferably, the four corners of the bottom of the shell are provided with anti-skid pads. The non-slip mat avoids the battery to be placed and can slip when meeting external force, and protects the battery.

Preferably, a handle is mounted on the housing, the handle is n-shaped, and two ends of the handle are connected with the outer side wall of the housing. The handle can conveniently take the lithium battery.

Preferably, a hole cover is attached to the charging port. The handhole door gives the protection to the mouth that charges, avoids the mouth that charges to fall into dust or water and leads to the battery damage.

The utility model has the beneficial effects that: the purpose of displaying electric quantity is achieved; the charging safety is ensured; the waste caused by the fact that the electric quantity is always displayed is avoided; the anti-slip mat prevents the battery from slipping when being placed under external force, so as to protect the battery; the handle can be used for conveniently taking the lithium battery; the handhole door gives the protection to the mouth that charges, avoids the mouth that charges to fall into dust or water and leads to the battery damage.
