Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the child car seat comprises a base 5 and a seat 6 disposed on the base, and the ISOFIX connecting mechanism of the child car seat of the present invention is disposed on the base 5.
As shown in fig. 2-10, the utility model discloses an ISOFIX coupling mechanism includes ISOFIX coupling assembling 2 and tears energy-absorbing device, ISOFIX coupling assembling 2 can set up on base 5 along fore-and-aft direction with sliding, it sets up between base 5 and ISOFIX coupling assembling 2 to tear the energy-absorbing device including setting up the portion 3 of tearing on base 5 or ISOFIX coupling assembling 2, when the car bumps, because inertia, relative slip takes place between base 5 and the ISOFIX coupling assembling 2, relative motion between base 5 and the ISOFIX coupling assembling 2 makes the portion 3 of tearing torn by, tear the portion 3 and progressively absorb the produced impact energy of car collision by the tearing in-process, thereby the injury that the reducible car collision led to the children that lie in the children's car seat.
ISOFIX coupling mechanism still includes locking piece 4 that is used for fixed ISOFIX coupling assembling 2 and the relative position of base 5, and locking piece 4 sets up on ISOFIX coupling assembling 2, is provided with on base 5 with locking piece 4 matched with locked groove 11, and locked groove 11 is provided with a plurality ofly, and a plurality of locked groove 11 set up on base 5 along the fore-and-aft direction interval, foretell tear portion 3 is the interlayer that sets up between per two adjacent locked groove 11. When the child car seat is installed on the car seat, the locking piece 4 is inserted into the locking groove 11, as shown in fig. 2-6, so that the position between the base 5 and the ISOFIX connecting assembly 2 is locked, and the base 5 is prevented from driving the seat 6 to slide in the use process; when the automobile collides, the seat 6 and the base 5 both slide forward relative to the ISOFIX connecting assembly 2 due to inertia, and when the base 5 and the locking member 4 slide relative to each other, the locking member 4 tears the interlayer, as shown in fig. 7 to 10.
The locking member 4 has a locking hook 41, the locking hook 41 being inserted in the locking groove 11 when the child car seat is mounted on the car seat, the locking hook 41 having a rearwardly extending tip 41a, the tip 41a acting on the barrier when relative sliding movement occurs between the base 5 and the locking member 4, thereby tearing the barrier.
After the interlayer between two adjacent lock grooves 11 is torn, two adjacent lock grooves 11 are communicated, the locking piece 4 slides from the previous lock groove 11 to the next lock groove 11, when the tip 41 of the locking piece 4 abuts against the next interlayer, the next interlayer is torn, and accordingly, the locking piece 4 gradually tears a plurality of interlayers along the sliding direction of the base 5, and in the process, the effects of buffering and energy absorption are achieved.
After the partition layer is torn, a channel 31 communicating two adjacent lock grooves 11 is formed on the partition layer, and the width of the channel 31 is not larger than that of the two adjacent lock grooves 11, so that the locking piece 4 can enter the next lock groove 11 and tear the partition layer connected with the next lock groove 11.
In this embodiment, the plurality of locking grooves 11 extend along the same straight line direction, and the widths of the partition layers between two adjacent locking grooves 11 are the same.
In this embodiment, the outer tube 1 extending along the front-back direction is disposed on the base 5, the outer tube 1 has a hollow cavity extending along the length direction of the outer tube, one end of the ISOFIX connecting assembly 2 is disposed in the cavity of the outer tube 1 and can be slidably disposed along the length extending direction of the outer tube 1, and the locking groove 11 is disposed on a sidewall of the outer tube 1. The distance between each interlayer and the two side edges of the outer tube 1 is the same, so that the stress of the whole child car seat can be balanced.
Preferably, outer tube 1 is connected with base 5 looks detachably, like this, after the car takes place to bump, only change outer tube 1 can, need not to change whole children's car seat to can avoid extravagant.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
