Abstract
The utility model belongs to the filed of the security guard circuits, and particularly relates to a baby carriage charging security guard circuit. The grounding terminal of a remote control receiving control circuit is connected in parallel with the grounding terminal of an electric control circuit; the grounding terminals connected in parallel are accessed into the charging grounding disconnecting pin of a charging circuit, and the grounding disconnecting pin is contacted with a movable power supply grounding terminal copper piece. When the baby carriage is in charging state, the plug of a charger is inserted into the socket of the charging circuit and presses the power supply grounding terminal copper piece to achieve the disconnection of the power supply grounding terminal copper piece and the charging grounding disconnecting pin, so that the grounding terminals of the remote control receiving control circuit and the electric control circuit are disconnected, the baby carriage can not operate due to power failure, the purpose of complete power failure during charging is achieved, current passing through a power-off switch is greatly reduced when the baby carriage is in normal operation state, the service life of the power-off switch is prolonged, and the stability of the circuits is enhanced.
Description
Technical field
The utility model relates to charging safety circuit field, a kind of safety protective circuit when specifically being the perambulator charging.
Background technology
At present, the Along with people's growth in the living standard, remote control/electric children vehicle is more and more in sale on the market, progresses into people's life.Because remote control/electric children vehicle itself is a kind of toy, so must consider child's safety problem in use.China GB19865-2005 and European IEC62115:2003 have done detailed regulation to each performance index of remote control/electric children vehicle, and wherein rechargeable battery is had following regulation: between charge period, toy cannot move.Therefore, on the perambulator circuit, the charging power-down circuit must be set.Charging power-off method commonly used at present is a deenergization feeder ear when car charges; Though can reach the purpose of charging outage like this; But the electric current of the power supply side of flowing through during owing to the car operate as normal is bigger, so shortened the life-span of cut-off switch, causes the instability of circuit.
The utility model content
To the shortcoming of above-mentioned standard to the related request and the existing charging power-down circuit of charging circuit, the purpose of the utility model provides a kind of charging power-down circuit, thereby makes perambulator automatic disconnection control power supply when charging realize safe charging.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of perambulator charging safety protective circuit; Form by remote-control reception control circuit, electronic control circuit and charging circuit; It is characterized in that: the earth terminal of said remote-control reception control circuit is parallelly connected with the earth terminal of electronic control circuit, and disconnected lower margin of charging and the disconnected lower margin of this charging that the earth terminal after the parallel connection inserts in the charging circuit contact with the power ground end copper sheet that can realize displacement.
After adopting foregoing circuit; When car was in charged state, Charger (portable round) inserted the socket of charging circuit, extruding power ground end copper sheet; The disconnected lower margin of itself and charging is broken off; Thereby break off the earth terminal of remote-control reception control circuit and electronic control circuit, the car outage can not be worked, the purpose of thoroughly cutting off the power supply when reaching charging.The utility model is compared the advantage that is had with prior art: flow through the electric current of cut-off switch in the time of can reducing the car operate as normal greatly, thereby prolong the life-span of cut-off switch, improve the stability of circuit.
Description of drawings
Fig. 1 is perambulator charging safety protective circuit theory diagram.
Fig. 2 is the disconnected lower margin action of charging sketch map.
Fig. 3 is the circuit diagram of perambulator charging safety protective circuit.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is carried out detailed explanation.
As shown in Figure 1, remote-control reception control circuit earth terminal and electronic control circuit earth terminal link together and are common ground end G, and open with power ground end GND branch, then it are received the disconnected lower margin 2 of charging of charging socket 1.The disconnected lower margin 2 of charging contacts with power ground end copper sheet 4, and copper sheet 4 is subjected to displacement under the extruding situation.
Can see that with reference to figure 2 when car was in normal operating conditions (non-charged state), the disconnected lower margin 2 of charging was connected together through common ground end G and power ground end, make the car can operate as normal; When car was in charged state, Charger (portable round) 3 inserted charging socket 2, extruding power ground end copper sheet 4; The disconnected lower margin 2 of itself and charging is broken off; Thereby break off remote-control reception control circuit and electronic control circuit earth terminal, car can not be worked, reach the purpose of charging outage.
Under the situation of car operate as normal, because main current loop is for to flow back to battery terminal negative from the battery positive voltage flow direction motor again, electric current is greatly about about 3A.And control circuit (comprising remote-control reception control circuit and electronic control circuit) is so owing to there is not the high-power components operating current smaller, approximately have only 100mA.So to bring in the purpose that reaching the charging outage much littler than the flow through electric current of cut-off switch of deenergization feeder ear with breaking off control circuit ground connection, thereby can prolong the life-span of cut-off switch, improve the stability of circuit.
