When the base 10 is mounted on the car seat 30, it has a preset working position, in which the included angle between the bottom surface 11 of the base body 1 and the horizontal plane is a preset value, and the included angle between the inclined extension direction of the basket back 201 and the vertical plane is correspondingly another preset value, and the other preset value is the preset inclination angle of the back 201 when the child sits on the safety seat, and comfortable leaning can be obtained. The adjustment of the reclining angle of the basket back 201 is also automatically achieved when the base angle adjustment mechanism adjusts the mounting angle of the base 10.
The following briefly describes the installation adjustment process of the child car seat of the present embodiment:
referring to fig. 1 and 2, the child car seat is first placed on the car seat 30, the base body 1 and the angle adjusting seat 2 are supported on the car seat 30 together, the locking mechanism is in an unlocked state, and the gravity hammer lever 4 and the nut 6 are disengaged from each other. After the connectors 12 on the left and right sides of the base 10 are respectively connected with the interfaces on the automobile seat 30, the rotary handle 83 is rotated and pressed down, so that one end of the tensioning rope 86 is gradually wound on the rotary handle 83 to drive the base body 1 to move backwards, and the pulling rope 81 is tensioned to drive the nut 6 to rotate relative to the screw 5 and further move downwards along the screw 5.
When the nut 6 moves downwards along the screw 5, the screw 5 is driven to swing forwards around the third shaft 51 relative to the angle adjusting seat 2, and meanwhile, the base body 1 and the angle adjusting seat 2 are turned around the first shaft 3 relatively in the front-back direction; in this process, the gravity hammer lever 4 makes translational movement in the front-rear direction and the up-down direction only with the turning movement of the base body 1 due to the effect of its own gravity.
After the nut 6 rotates until the protrusion 61 on the outer periphery thereof is clamped into the locking groove 42 on the lower end portion of the gravity hammer rod 4, the rotating handle 83 is continuously pressed down, the protrusion 61 and the locking groove 42 are mutually embedded to enable the nut 6 and the gravity hammer rod 4 to slightly swing synchronously until the nut 6 and the gravity hammer rod 4 are mutually locked, and the base body 1 and the angle adjusting seat 2 are relatively stable and non-rotatable, as shown in fig. 3 and 4, the locking mechanism between the base body 1 and the angle adjusting seat 2 is locked, the rotating handle 83 is also locked by the pawl 84, at the moment, the included angle between the bottom surface 11 of the base body 1 and the horizontal plane reaches a preset value, and the inclination angle of the backrest 201 of the seat 20 also reaches a preset value, so that an infant in the seat 20 can obtain the leaning experience of the optimal comfort angle. In the above process, the base 10 slides backward relative to the connector 12 to gradually approach the automobile backrest 40, so that the adjustment of the front and rear positions of the base 10 and the one-key tightening of the connector 12 are realized.
When the locking of the locking mechanism needs to be released, the locking of the rotating handle 83 is released, then the tensioning rope 86 is released, then the pulling rope 81 is released, the nut 6 moves upwards along the screw 5, the base body 1 and the angle adjusting seat 2 correspondingly swing around the first shaft 3 back and forth, the gravity hammer rod 4 is driven to translate, the protrusion 61 on the nut 6 is gradually separated from the locking groove 42 at the lower end part of the gravity hammer rod 4, and the unlocking of the locking mechanism is realized.
