In some embodiments, the warning lamp include the first warning lamp, one end of first warning lamp with
Positive pole connection, the other end are connect by a concatenated first resistor with the collector of the first triode, the one or three pole
The emitter of pipe is connect with power cathode, and the base stage of first triode is connect by a second resistance with positive pole, institute
The circuit stated between the collector and first resistor of the first triode is connect with power cathode.
In some embodiments, the warning lamp includes and the second warning lamp, one end of second warning lamp
It being connect with positive pole, the other end is connect by a concatenated 3rd resistor with the collector of the second triode, and the described 2nd 3
The emitter of pole pipe is connect with power cathode, and the base stage of second triode is connect by one the 4th resistance with positive pole,
The base stage of second triode is connect by one second capacitor with power cathode；First triode and the two or three pole
Pipe passes through a capacitance connection.
In some embodiments, the switch includes concatenated key switch and dry reed switch.
The utility model also provides a kind of child safety seat comprising above-mentioned safety circuit, including safety seat and peace
Whole circuit is provided with safety belt buckle and ISOFIX interface, the safety belt buckle and ISOFIX on the safety seat
Interface is provided with dry reed switch, the safety belt buckle and ISOFIX interface dry reed switch closure when loosening；
A trigger switch is provided in the cushion of the safety seat.
By using above-mentioned technical proposal, have the advantages that it compared with prior art
(1) the utility model includes the buzzer and warning lamp being arranged in parallel, the two complementary duty, can effectively avoid because
Carelessness problem causes not see that warning lamp flashes, and does not influence between each other, and warning lamp breaks down general simultaneously with buzzer
Rate is low, breaks down in the unwitting situation of user and still ensures that alert operation is normally carried out, improves the reliability of system.
(2) flashing function can be realized by the setting of simple circuit in warning light circuit part, eliminates chip controls
Situations such as programming problem saves cost, and since the chip anti-interference ability of tape program is not high, is easy to appear misprogramming, therefore
Barrier rate is higher.
(3) the alarm lamp LED bulb minimum, firm using volume, is easily installed, also avoids ordinary lamp and lantern rapid wear
It is bad, can children be caused with other injuries.Route by the way of double-colored flashing, can plus it is eye-catching, reinforce alarm function.
Detailed description of the invention
Fig. 1 is circuit diagram in the utility model embodiment；
Fig. 2 is for detailed circuit diagram at A in Fig. 1.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, in conjunction with following explanation,
The advantages of the utility model and feature will be apparent from, it should be noted that attached drawing is all made of very simplified form and non-essence
Quasi- ratio, only to facilitate the apparent purpose for aiding in illustrating the present embodiment.
Please refer to Fig. 1 and Fig. 2, a kind of safety circuit being adapted to child safety seat, including buzzer and parallel connection therewith
Warning lamp, warning lamp connects to power supply respectively with buzzer, a switch is provided on the main line where power supply, for controlling electricity
Road on-off.
Specifically, warning lamp includes the first LED and the 2nd LED, and one end of the first LED is connect with positive pole, the other end
It is connect by a concatenated first resistor R1 with the collector of the first triode VT1, the emitter and power supply of the first triode VT1
Cathode connection, the base stage of the first triode VT1 connected by the anode of a second resistance R2 and power supply, first triode
Circuit between the collector and first resistor R1 of VT1 is connect with power cathode.
One end of 2nd LED and the anode of power supply connect, and the other end passes through a concatenated 3rd resistor R3 and the two or three pole
The collector of pipe VT2 connects, and the emitter of the second triode VT2 and the cathode of power supply connect, the base of the second triode VT2
Pole is connected by the anode of one the 4th resistance R4 and power supply, and the base stage of the second triode VT2 is negative by first capacitor C1 and power supply
Pole connection；The collector of the base stage of first triode VT1 and the second triode VT2 pass through the second capacitance connection.
When energized, triode can compete energization because of element difference itself.Meeting of its kind is first powered, with first
For triode VT1 is first powered, the electrode voltage decline at the second both ends capacitor C2, the first LED are lighted at this time, the electricity of VT2 and first
Holding C1 both end voltage will not be bright close to zero, the 2nd LED.Continue to charge to first capacitor C1 when power supply passes through the 4th resistance R4, the
The base voltage of two triode VT2 can gradually rise, and when being more than certain voltage, the second triode VT2 becomes to lead from stationary state
Logical state, base voltage decline, the 2nd LED are lighted, and the second triode VT2 voltage is begun to decline at this time, passes through first capacitor C1
Effect so that the base voltage of the first triode VT1 is also begun to decline, the first triode VT1 becomes static from being connected, and VD1 is put out
It goes out, so recycles, generate the effect of flashing.
The switch includes key switch and dry reed switch, and key switch and dry reed switch are concatenated connection type,
Cooperation control safety circuit, it should be understood that the switchtype in the present embodiment is not limited to the key under mentioned kind, such as cushion
Switch or inductive pick-up, to identify whether to have children on the seat, i.e., the letter done on the basis of this programme thinking
Single modification should all be fallen into the protection scope of this programme.
This programme combination child safety seat is described further function in service stage, intrinsic safety whole circuit and conventional youngster
Virgin safety seat is used in combination, and key switch is arranged inside Chain cushion, and switch is in normally open, when there is children to be sitting in
The key switch is closed state when above；Dry reed switch be separately positioned on child safety seat safety belt buckle and
ISOFIX interface, and two dry reed switch are to be arranged in parallel, when safety belt buckle and ISOFIX interface are to be reliably connected shape
When state, dry reed switch is in an off state, and when wherein any one place's connection disconnects, the circuit at dry reed switch is on shape
State；When key switch and any one dry reed switch are closed, warning lamp flashing, meanwhile, buzzer makes a sound alarm, thus
Parent is reminded to check the connection of seat.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to
Above embodiment.Even if to the utility model, various changes can be made, if these variations belong to the utility model claims
And its within the scope of equivalent technologies, then still fall among the protection scope of the utility model.
