Drawings
FIG. 1 is a schematic diagram of the circuit of the present invention;
fig. 2-7 are 7 embodiments of the circuit of the present invention.
Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
The electric bicycle electric shock prevention charging socket shown in figure 1 is provided with a controllable on-off circuit, wherein the output end of the controllable on-off circuit is connected with the power supply input end of a battery in an electric bicycle; the input end of the controllable on-off circuit is connected with the power output end of a charger outside the electric vehicle; the controllable on-off circuit realizes the connection or disconnection of the circuit through a control signal of an external charger.
The controllable on-off circuit can be arranged on an integrated circuit board in the charging socket, and the charging socket is also provided with an input conductive terminal and an output conductive terminal; the input conductive terminal is connected with the charger in a charging state and comprises a charging terminal and a control signal terminal. The charging terminal is connected to a charging output of the charger and receives a charging voltage and a charging current of the charger. The controllable on-off circuit has the characteristic of controllable on-off through the combination of electronic components, and the circuit is in an on-off state through the control of the control signal terminal, so that the on-off state is formed between the input conductive terminal and the output conductive terminal. The output conductive terminal is connected with the battery through a lead.
When the charger is in a non-charging state, the plug of the charger is not inserted into the charging socket, and the control signal terminal of the charging socket does not receive the control signal sent by the charger, the internal circuit board (namely, the controllable on-off circuit) is in an off state, the input conductive terminal and the output conductive terminal are in an off state at the moment, no voltage is output on the input conductive terminal, and no matter whether a person touches the input conductive terminal or the short circuit of the input conductive terminal caused by other abnormity occurs, the person can not get an electric shock or the battery is not short-circuited.
When the charger is in a charging state, the output plug of the charger is inserted into the charging socket, the input conductive terminals cannot be touched by people and objects from the outside, the charger is safe from the outside, the circuit board in the charging seat outputs a control signal, and after the circuit board in the charging seat receives the control signal, an internal circuit is opened, so that the input conductive terminals and the output conductive terminals are connected, and the charger starts to normally charge the battery after the connection.
When the charger starts to charge the battery normally, if the charging plug is pulled out manually, the internal circuit board of the charging socket loses the external control signal and recovers to the disconnected state again, and no matter people touch the input conductive terminals or short circuit of the input conductive terminals caused by other abnormity does not cause electric shock of people or short circuit of the battery.
As shown in fig. 2 to 4, the controllable on-off circuit is implemented by using a photoelectric coupler, a MOS transistor, a resistor element, and the like.
As shown in fig. 2, the two interfaces of "charger output +/SC +" and "charger output-/SC-" are input power terminals on the charging socket and are responsible for connecting the power output of the external charger of the electric vehicle;
the interface of 'control signal +/KZ +' is a control signal terminal on the charging socket and is connected with a control signal of the charger;
the two interfaces of the battery load +/SR + 'and the battery load-/SR-' are output power terminals on the charging socket and are connected with the power input of the battery load in the electric vehicle.
The working principle of the circuit is as follows:
if an internal controllable on-off circuit is not provided, SC + and SR + are directly connected, and SC-and SR-are directly connected, at the moment, if SC + and SC-are short-circuited, a battery short circuit can be caused, and the hidden danger of fire can be caused; if the human body is short circuited SC + and SC-, there is a great risk of electrocution of the human body because the battery voltage is higher than 42V and there is no current limit.
When no control signal is input to KZ +, the optical coupler in the on-off control circuit does not work, the MOS tube in the controllable on-off circuit is in a closed state, the SC-and SR-are in an off state at the moment, the output loop of the battery is in an open circuit, and the short circuit of the SC + and SC-can not occur, so that the electric shock of a person can not be caused.
The operation principle of the circuits shown in fig. 3-4 is the same as that of fig. 2, and will not be described repeatedly here.
Fig. 5-7 show the manner in which the controllable on-off circuit is implemented by using a relay element, and the operation principle of the circuit is basically the same as that of fig. 2, and will not be described repeatedly here.
While particular embodiments of the present invention have been described in the foregoing specification, various modifications and alterations to the previously described embodiments will become apparent to those skilled in the art from this description without departing from the spirit and scope of the invention.
