Standby battery box for electric cylinder

摘要

A standby battery box for an electric cylinder is electrically connected to a control box for driving the electric cylinder and includes a charge-discharge device and a rechargeable battery. The charge-discharge device includes a protection unit, a power conversion unit, a voltage detection unit, a control unit, a discharge unit, a display unit, and a switch unit. The rechargeable battery is electrically connected to the charge-discharge device. When a startup switch of the switch unit is pressed, the charge-discharge device delivers the electricity of the rechargeable battery into the control box. When a shutoff switch of the switch unit is pressed, the charge-discharge device does not supply power, thereby protecting the standby battery box from being exhausted.

1. A standby battery box for an electric cylinder, electrically connected to a control box for driving the electric cylinder and including:
a charge-discharge device comprising a discharge unit and a switch unit electrically connected to the discharge unit, the discharge unit comprising a transistor electrically connected to a voltage end; and a rechargeable battery electrically connected to the charge-discharge device; wherein the switch unit comprises a shutoff switch and a startup switch, the shutoff switch and the startup switch electrically connected to the transistor; the transistor is in opened circuit and no power is supplied to the voltage end when the shutoff switch is pressed; after the control box is supplied with AC power, the AC power is supplied to the voltage end even when the shutoff switch is still pressed; electrical power is supplied from the rechargeable battery to the voltage end and the transistor is kept turning on when the startup switch is pressed, whereby the voltage end still has power even through the startup switch is released.
