Description

A retractable child safety seat side anti-collision mechanism

technical field

The utility model relates to the field of child safety seats, in particular to a retractable side anti-collision mechanism of the child safety seat.

Background technique

The traditional car seat belt has saved countless lives as a safety device. But the current three-point safety belts are all designed according to the figure of adults, and it is inappropriate to directly use them for children without improvement. Even, because children's height is insufficient, when using existing vehicle safety belt, seat belt often can pass through from child's neck, and in case of emergency like this, seat belt can strangle child's neck, thereby causes additional damage to child. s damage. Therefore, in order to give children a safer riding environment, child safety seats have emerged as the times require. At present, child safety seats have been used by more and more parents in the car to provide children with a safer ride experience. But the side of child safety seat currently on the market does not have additional protection device. Therefore, when the side of the child safety seat is collided, the impact force will directly act on the child safety seat, which may cause damage to the child safety seat, and then may cause harm to children sitting on the child safety seat. Therefore, if a protruding anti-collision mechanism can be added to the side of the child safety seat, the child safety seat will be safer. However, if a protruding anti-collision mechanism is added to the side of the child safety seat, the outer contour size of the child safety seat will increase, thereby causing inconvenience to packaging and transportation. How to deal with the above contradictions has become a difficult problem.

Both sides of the child safety seat are provided with mounting seats, the bottom surface of the mounting seat is provided with a push-type lock, the mounting seat is also provided with a card slot, and the mounting seat is inserted with an anti-collision A first elastic body is provided between the anti-collision block and the mounting seat, a groove A is provided on the anti-collision block, and a downwardly protruding lock is provided on the outer surface of the bottom of the groove A. A through hole A is provided on the side wall of the groove A, a button is inserted in the groove A, and a second elastic body is arranged between the button and the anti-collision block. The button is provided with a through guide hole, the guide hole includes an inclined side wall A, a support column passes through the through hole A and the guide hole, and leans against the mounting seat to block the anti-collision block Moving toward the mounting seat, one end of the third elastic body is connected to the support column, and the other end is connected to the anti-collision block. When the button is pressed, the support column is in the guide hole Slide under the action of the side wall A on the top, and deform the third elastic body, after it slides into the card slot, the anti-collision block can move towards the mounting seat, until the locking block is locked by pressing Lock it, and the anti-collision block is received in the mounting seat. In this way, the anti-collision block is stored in the mounting seat during packaging to reduce the volume. When in use, the push-type lock is unlocked. The anti-collision block protrudes and is supported by the support column and cannot be retracted, so that the child safety seat is hit by the side. When the anti-collision block is impacted before the child safety seat, the child safety seat is prevented from being directly impacted by the side and provides safety.
