Background technology
Along with children or infants's safety by bus constantly comes into one's own, the use of child safety seat is more and more wider
General.Currently used child safety seat mainly uses LATCH belt-fastening system and ISOFIX safety
Band fixed system both fixed systems, but no matter use the safety seat of which kind of fixed system, and it makes
Safety belt restraining system be the most all cluster and lock catch type.
Cluster child safety seat by using the seat belt of vehicle or the seat belt of safety seat, according to
Child is fixed on safety seat by certain rule.Lock catch type child safety seat is by using safety seat
The seat belt carried, after child is seated in, by seat belt folding and unfolding to suitable tightness, is inserted into lock
Smash.The fixing means of cluster child safety seat is complex, and due to seat belt fastening force not
Foot, can not effectively absorb impact force, even occur that seat belt gets loose and cause bigger injury during collision.
Seat belt on lock catch type child safety seat will not get loose, and protected effect is preferable, but seat belt itself is deposited
In a certain amount of free travel, or due to seat belt jack locking deficiency, safety during collision occurs
Band can not child on locked seat, cause the children's torso on seat to skid off, cause child injured.
To this end, applicant carried out useful exploration and trial, have found result of the above problems,
Technical scheme described below produces under this background.
Utility model content
Technical problem to be solved in the utility model: for existing cluster or lock catch type children's safety
There is the not enough problem of security performance and a kind of protected effect being effectively improved when colliding be provided in seat
Child safety seat seat belt pre-tightening device.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of child safety seat seat belt pre-tightening device, including:
One anchor switch detection sensor, described anchor switch detection sensor detection safety belt lock catch switch
State also produces an anchor switch status signal；
The safety belt pretensioner of one seat belt for tightening up and on locking child safety seat；And
One collision detection being connected with described anchor switch detection sensor and safety belt pretensioner respectively controls
Unit, described collision detection control unit include power supply, signal detection module, acceleration detection module with
And preloader drives module, described signal detection module receives what described anchor switch detection sensor produced
Anchor switch status signal also determines described collision detection control unit in a dormant state or duty,
Described acceleration detection module detects the acceleration of vehicle in real time time in running order, when described acceleration
Detection module detects when the acceleration of vehicle reaches crash acceleration, and described collision detection control unit is produced
Raw one drives signal to drive module to described preloader, described preloader drive module receive described in drive
Safety belt pretensioner described in dynamic signal rear drive tightens up and locking.
In a preferred embodiment of the present utility model, described power supply is for being integrated in described collision detection control
Battery in unit processed.
In a preferred embodiment of the present utility model, described collision detection control unit also includes a report
Alert module, when described alarm module detects the electricity of described battery less than electricity set in advance, institute
Stating alarm module reminds user to change battery by the way of bright light or buzzer call.
In a preferred embodiment of the present utility model, described collision detection control unit is arranged on child
The back of safety seat or bottom.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: this utility model
Whether taken advantage of on child safety seat to determine by collision detection control unit detection safety belt lock catch switch
Member, by detection value of vehicle acceleration is judged whether in the case of occupant is seated on child safety seat again
Colliding, collision detection control unit drives safety belt pretensioner to tighten up and locking peace when colliding
Full band.So it is effectively improved protected effect when child safety seat collides.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.
Seeing Fig. 1 and combine Fig. 2 and Fig. 3, be given in figure is that a kind of child safety seat seat belt is pre-
Tightening device, including anchor switch detection sensor 100, safety belt pretensioner 200 and collision detection control
Unit 300 processed.
Anchor switch detection sensor 100 is arranged on the safety belt lock catch switch 11 of child safety seat 10
In.Anchor switch detection sensor 100 detects the state of safety belt lock catch switch 11 and produces a snap close
