Position is sent out, the children car seat further includes the trigger device that the passive protective device is triggered based on trigger signal, described
Trigger device is connect with the connector and the sending when the connector is converted by the initial position to the trigger position
The trigger signal.
Preferably, the initial position is located at the front of the trigger position, and the automobile is when meeting with collision, the company
Fitting and the fixed frame switch to the trigger position by the initial position with respect to sliding along the longitudinal direction.
Preferably, the connector is fixedly set on the interface shelf, is offered along the longitudinal direction on the fixed frame
The guide groove of extension, when the connector is located at initial position, the connector is located at outside the guide groove；When the connection
When part is converted by the initial position to the trigger position, the connector backs through the guide groove and reaches the touching
Send out position.
Further, the notch height of the guide groove is less than the height of the connector.
Further, the mounting groove ordinatedly worn for the connector, the installation are also provided on the fixed frame
Slot position in the guide groove front side and be connected with the guide groove, the corresponding initial bit in the position of the mounting groove
It sets.
Further, the limiting slot ordinatedly worn for the connector, the limit are also provided on the fixed frame
Slot position in the guide groove rear side and be connected with the guide groove, the corresponding trigger bit in the position of the limiting slot
It sets.
As a preferred embodiment, the connector is columnar connecting shaft.
Preferably, the fixed frame, the interface shelf and the connector are rigid member.
Preferably, the passive protective device is the air bag for including airbag body, when the connector is in described
When trigger position, the airbag body inflation.
Further, the air bag further includes the gas generator for supplying to the airbag body, the touching
Transmitting apparatus includes the control switch for controlling the gas generator working condition, when the connector is in the initial bit
When setting, the control switch is disconnected；When the connector is in the trigger position, the control switch closure, the gas
Body generator inflates work to the airbag body.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages: of the invention has
The automobile seat for child of passive protective device, wherein passing through the fixed frame and interface that are set as connecting by connector by connection frame
Frame, when automobile, which is met with, to be collided, since inertia impact causes the relative displacement of fixed frame and interface shelf, so that connector is in fixation
Position on frame changes, and trigger signal is issued and the change by the position, so that trigger device triggering is passive
Protective device works and provides the protection of the child.Using the trigger architecture of this kind of mechanical structure, not only cost is relatively low, but also reliability
It is higher, improve the safety that children use automobile seat for child to ride.

Specific embodiment
Technical solution of the present invention is further elaborated in the following with reference to the drawings and specific embodiments.
Referring to shown in Fig. 1 to Fig. 3, a kind of children car seat with passive protective device comprising seat body 100
With the connection frame 200 for connecting with automobile, passive protective device is set in seat body 100.Connection frame 200 includes fixedly
The fixed frame 1 that is connected in seat body 100, the interface shelf 2 being fixedly attached to by connector 3 on fixed frame 1, connector
3 cause the trigger position b of conversion with initial position a on fixed frame 1 and by car crass.The children car seat further includes
The trigger device of passive protective device is triggered based on trigger signal, the trigger device connect with connector 3 and connector 3 by
Initial position a issues above-mentioned trigger signal when converting to trigger position b.
Specifically, seat body 100 is used to carry the shell 20, Yi Jike of children including pedestal 10, on pedestal 10
Releasably connect the block 30 on the housing 20 to form enclosing on front side of children's torso.Connection frame 200 is from after the bottom of pedestal 10
Portion extends back, and interface shelf 2 is equipped with ISOFIX connector, is connected by the ISOFIX interface on the ISOFIX connector and car seat
It connects and automobile seat for child is fixedly connected on car seat.
Shown in Figure 2, initial position a is located at the front of trigger position b, when automobile, which is met with, to be collided, since inertia is made
With, seat body 100 travels forward together with fixed frame 1, so that the opposite sliding along the longitudinal direction of connector 3 and fixed frame 1, thus
So that connector 3 switches to trigger position b by initial position a.
Specifically, fixed frame 1, interface shelf 2 and connector 3 are rigid member, and connector 3 is fixedly set on interface shelf 2,
The guide groove 4 extended along the longitudinal direction is offered on fixed frame 1, the notch height of the guide groove 4 is less than the height of connector 3,
When connector 3 is in initial position a, connector 3 is located at outside guide groove 4；When connector 3 is converted by initial position a to triggering
When the b of position, connector 3 squeezes backward and passes through guide groove 4 and reach trigger position b.
In the present embodiment, it is columnar connecting shaft 3 that connector 3, which uses, and the notch height of guide groove 4 is less than connecting shaft 3
Diameter.The mounting groove 5 and limiting slot 6 ordinatedly worn for connecting shaft 3 is also provided on fixed frame 1, mounting groove 5 is located at guiding
The front side of slot 4 is simultaneously connected with guide groove 4, and limiting slot 6 is located at the rear side of guide groove 4 and is connected with guide groove 4, mounting groove 5
Position it is corresponding be initial position a, the position of limiting slot 6 it is corresponding be trigger position b.
In the present embodiment, it is the air bag for including airbag body 9 that passive protective device, which uses, which also wraps
The gas generator 8 for supplying to airbag body 9 is included, trigger device includes for controlling 8 working condition of gas generator
Control switch 7, when connecting shaft 3 is in initial position a, control switch 7 is disconnected, and gas generator 8 is not filled into airbag body 9
Gas；When connecting shaft 3 switches to trigger position b by initial position a caused by colliding because of automobile, control switch 7 is closed, gas
Generator 8 inflates work into airbag body 9 so that airbag body 9 moment inflation and the protection of the child is provided.
In the present embodiment, airbag body 9 is set on block 30, can be set to the top of block 30, with the energy in inflation
It is enough to expand rapidly and be covered on the upper surface of block 30, so that occupant hits when head caused by because of impact is swung forward
What is hit is the inflatable air cushion of elasticity, to effectively be protected to the head of occupant, neck；Block can also be set to
30 bottom, with inflation when airbag body 9 can expand expansion and be covered on the lower surface of block 30, to be blocked in
Between the lower part of block 30 and the both legs of occupant, to limit the forward displacement of occupant, further decrease or avoid to take
Person automobile meet with enormous impact when caused by damage；It can also be set to the inside of block 30, made upward simultaneously in inflation
Expansion expansion is unfolded with expansion downwards.
To sum up, automobile seat for child of the invention passes through the fixed frame 1 for being set as connecting by connector 3 by connection frame 200
With interface shelf 2, when automobile meet with collide when, since inertia impact causes the relative displacement of fixed frame 1 Yu interface shelf 2 so that company
Position of the fitting 3 on fixed frame 1 changes and reaches trigger position b, and triggering letter is issued when reaching trigger position b
Number, so that trigger device triggers passive protective device work according to the trigger signal and provides the protection of the child.The present invention
The middle trigger architecture using this kind of mechanical structure, not only cost is relatively low, but also reliability is higher, improves children and uses children's vapour
The safety that vehicle seat is ridden.
