The children carrier weight of integrative injection moulding among the correlation technique is overweight, still need continue the lightweight could make things convenient for the trip to carry more, the structure weight of children carrier mainly concentrates on the junction of body bedplate and back, only lightweight direction is exactly that the junction structure of body bedplate and back subtracts the weight, nevertheless the safety standard test needs high-speed collision safety seat around, consequently, it is higher to the structural strength requirement of body bedplate and back junction, children carrier among the correlation technique is difficult to subtract the weight to the junction structure of body bedplate and back again under the prerequisite that satisfies regulation test requirement.
In addition, the consumer thinks that integrative injection moulding's body subassembly volume is too big among the correlation technique, and inconvenient accomodating is carried the trip, expects that the body subassembly can fold to reduce the volume and conveniently accomodate more and carry the trip. To meet the folding requirements, it is necessary to add a folding mechanism and a locking mechanism to the junction of the body seat and backrest of the child carrier, which results in an increase in the weight of the individual body assembly.
Fig. 1 is an exploded view of some embodiments of a child carrier according to the present disclosure, in view of which, in one aspect of the embodiments of the present disclosure, there is provided a child carrier comprising: the vehicle comprises a vehicle body 1, a rear joint component, a front foot component 3, a connecting rod component 4, a rear foot component 2 and a sliding groove component. The carrier body 1 is provided with a back plate component and a seat plate, and the rear joint component is arranged on the carrier body 1. One end of the front foot component 3 far away from the ground is rotatably connected with the seat board, one end of the connecting rod component 4 is connected with the front foot component 3, and the other end of the connecting rod component 4 is connected with the rear joint component. The hindfoot assembly 2 is connected to the posterior joint assembly and is rotatable relative to the linkage assembly 4.
Fig. 2 (a) is a schematic structural diagram of a second state of some embodiments of the child carrier according to the present disclosure, and fig. 2 (b) is a schematic structural diagram of a first state of some embodiments of the child carrier according to the present disclosure, and referring to fig. 2 (a) and (b), the sliding groove assembly is disposed on the back plate assembly, and the rear joint assembly is slidably connected with the sliding groove assembly and can slide and rotate on the sliding groove assembly, so that the child carrier can be switched between the first state and the second state. Under first state, children's carrier is in the expansion state, and backplate subassembly, bedplate and link assembly 4 form triangle-shaped bearing structure this moment, and link assembly 4 supports and forms triangle-shaped between bedplate and backplate subassembly, has effectively increased the resistance back of the body when backplate subassembly is bent forward, consequently can greatly simplify the atress structure between bedplate and the backplate subassembly, realizes subtracting heavy effect. In the second state, the child carrier is in a collapsed state, and the seat plate, the front leg assembly 3 and the linkage assembly 4 form a triangular support structure, and no new structural weight needs to be added for the transition from the first state seat mode to the second state stroller mode.
The triangular supporting stress structure formed by the back plate assembly, the seat plate and the connecting rod assembly 4 in the first state can simplify the stress structure of the independent carrier body 1 in the use state as a steam seat, so that the original stress structure of the carrier body 1 can be lightened and designed to reduce weight, and particularly, the load structure of the carrier body 1 needing to be added with a folding mechanism and a locking mechanism is lightened and designed to realize remarkable weight reduction effect. The triangular support stress structure in the second state formed by the quick switching of the first state can be unfolded to stably push the front and rear foot assemblies 2 of the baby carriage.
