A child car seat with a three-point seatbelt restraint, as shown in fig. 1 to 3, which mainly relates to a child car seat with a three-point seatbelt restraint, the structure of which is composed of a body 1, a seat member 2, a headrest 4, a guide 5, a locking member 6, and the like.

The headrest 4 is arranged in the middle of the top of the body 1, the bottom of the headrest 4 is provided with a rectangular mounting plate 41 which extends downwards as shown in fig. 5, two outer sides of the mounting plate are respectively provided with a sliding rib 42, the seat members 2 are provided with two as shown in fig. 9, the two seat members 2 are respectively fixedly arranged on two sides of the headrest 4, namely the body 1 on two sides of the mounting plate 41, and the inner side of each seat member 2, namely one side of the adjacent mounting plate 41 is provided with a sliding groove 21; thus, the mounting plate 41 can be installed in the sliding grooves 21 on the inner sides of the two seat members 2 only through the sliding ribs 42 on the two outer sides in a lifting and moving manner, namely the headrest 4 can be installed at the top of the body 1 in a lifting and moving manner, and the connected back plate 3 is further arranged between the two seat members 2, so that the appearance of the seat is attractive.

The headrest 4 on be equipped with guide 5, this guide usually can be according to left and right position difference fixed connection in headrest 4 both sides, this is because children's car safety seat can install in car left side or car right side, and this makes the use of three-point type safety belt also can have left and right differentiation, so design two guides 5 and just can satisfy above-mentioned operation requirement.

Since the guides 5 on both sides and other components configured thereon are all the same in structure, and are arranged at symmetrical positions on the child car seat, the present embodiment will be described in detail by taking only the guide 5 on one side and other components configured thereon as an example.

The guide 5 is provided with a guide hole 51 for guiding the movement of the safety belt to pass through as shown in fig. 6 and 7, an opening 52 for the side surface of the safety belt to be installed in the guide hole is arranged on the outer side of the guide hole, and a locking piece 6 for elastically closing the opening is arranged on the opening.

The guide piece 5 is provided with a linkage rod 8 which is installed in a seesaw mode, the linkage rod is a long rod which is slightly bent, and the linkage rod 8 is movably assembled on a short shaft 53 on the back surface of the guide piece 5 through a small hole 81 in the middle part, so that two ends of the linkage rod 8 can form a movable structure similar to a seesaw around the short shaft 53; and, the inner end of gangbar 8 is connected on locating part 7, and the outer end contacts on locking piece 6.

Wherein, the inner end of the gangbar 8 and the connection structure of the locating part 7 are: firstly, an installation groove 43 is arranged on the headrest 4, a limiting piece 7 and a pressure spring 9 at the inner end of an elastic pushing limiting piece are arranged in the installation groove, and the limiting piece 7 always tends to move axially outwards under the elastic pushing of the pressure spring in a normal state; then, a '/' shaped chute 71 is arranged on the limiting piece 7, the highest point of the chute is close to the inner end of the limiting piece 7, and the lowest point of the chute 71 is close to the outer end of the limiting piece 7; finally, a linkage block 82 is correspondingly arranged at the inner end of the linkage rod 8, and the linkage block needs to be slidably assembled in the inclined groove 71.

And the structure that the outer end of the linkage rod 8 is contacted with the locking piece 6 is as follows: one end of the locking piece 6 and the torsion spring 10 are coaxially hinged on a torsion spring shaft 54 on the back surface of the guide piece 5, and two support legs of the torsion spring 10 are respectively pushed against the other end of the locking piece 6 and the guide piece 5, so that the other end of the locking piece 6 is driven by the torsion force of the torsion spring 10 in a normal state and can be upwarped to contact with the outer end of the linkage rod 8, and meanwhile, the locking piece 6 can elastically close the opening 52 of the guide hole 51.

Meanwhile, the outer end of the limiting member 7 is further provided with a guide block 72, the inner side surface of the seat member 2 is provided with a guide groove 22 arranged adjacent to the sliding groove 21, the top of the guide groove is provided with a boss 23, and the guide block 72 needs to be slidably assembled in the guide groove 22, and the purpose of designing the structure is as follows: when the guide block 72 slides in the guide groove 22, the limiting piece 7 is pushed by the elasticity of the compression spring 9 to move axially outwards; when the guide block 72 slides along the guide groove 22 to the boss 23, the stopper 7 compresses the compression spring 9 to move axially inward.

Therefore, the utility model discloses a specific working process as follows: when the headrest 4 rises and moves to the top of the body 1 as shown in fig. 2 and 3, the limiting member 7 is driven to rise synchronously, the guide block 72 on the limiting member can move upwards to the boss 23 along the guide groove 22, the limiting member 7 can compress the compression spring 9 and move axially inwards, so that the linkage block 82 at the inner end of the linkage rod 8 slides to the lowest point of the inclined groove 71, the outer end of the linkage rod 8 can be driven to upwarp through the seesaw principle, the unlocking locking member 6 can elastically close the opening 52, that is, the locking member 6 elastically closing the opening 52 can be unlocked to press downwards to leave the opening 52, and the safety belt can be loaded into the guide hole 51 of the guide member 5 from the opening 52 for use; of course, the boss 23 at the top of the guide groove 22 is usually designed with a stroke, which aims to enable the headrest 4 to be adjustable at different heights even if the headrest is located at the top of the body 1, that is, when the guide block 72 shown in fig. 2 just enters the boss 23, the locking member 6 can be unlocked through the limiting member 7 and the linkage rod 8, and when the guide block 72 exceeds the position shown in fig. 2 and continues to slide upwards on the boss 23 to the position shown in fig. 3, that is, when the headrest 4 continues to move upwards to the highest position at the top of the body 1 shown in fig. 3, the locking member 6 is always in the unlocked state.

When the headrest 4 descends and moves away from the top of the body 1 to the position shown in fig. 1, the limiting member 7 is driven to descend synchronously, the guide block 72 on the limiting member 7 also slides downwards to disengage from the boss 23 to be assembled in the guide groove 22 again, the compression force on the compression spring 9 is released, the elastic pushing limiting member 7 moves outwards and resets axially, the linkage block 82 at the inner end of the linkage rod 8 slides to the highest point of the chute 71, the outer end of the linkage rod 8 is driven to press downwards through the rocker principle to lock the elastic closing of the locking member 6 on the opening 52, that is, the locking member 6 elastically closing the opening 52 is in the locking state again and cannot press downwards to leave the opening 52, the safety belt cannot be loaded into the guide hole 51 of the guide member 5 from the opening 52 for use, so that the children of smaller ages can be effectively limited to the child car safety seat bound by the three-point safety belts, and eliminates the potential safety hazard of using the child car seat.

In addition, the locking member 6 is prevented from being misused at the moment from the unlocked state to the locked state, which is the moment when the guide block 72 just leaves the boss 23 and enters the guide groove 22.

The above description is only an embodiment of the present invention, and those skilled in the art should understand that any structural design similar to the embodiment is included in the protection scope of the present invention.
