In addition, the width of the limiting groove 101 is slightly larger than the thickness of the bottom back 200, so that enough swing allowance is reserved for the bottom back 200. During production design, the size of the limiting groove 101 and the size of the bottom back 200 can be set as required, so that the swing angle of the bottom back 200 relative to the base 100 around the axis of the rotating shaft part 201 is in a certain range (for example, 5 to 20 degrees).
As shown in fig. 1 and 5, the chair back 300 is connected with the bottom back 200 by a pin assembly 400;
the pin assembly 400 passes through the seat back 300 and the bottom back 200, and the pin assembly 400 is detachable with respect to the seat back 300 and the bottom back 200.
When the chair back 300 needs to be disassembled, the pin shaft assembly 400 is axially pulled out, so that the chair back 300 can be separated from the bottom back 200.
Further, the pin assembly 400 includes a rotation shaft 410;
the bottom back 200 is provided with a first shaft hole 202, the chair back 300 is provided with a second shaft hole 301, the first shaft hole 202 is coaxial with the second shaft hole 301, and the rotating shaft 410 penetrates through the first shaft hole 202 and the second shaft hole 301.
The seat back 300 can swing around the rotation shaft 410 relative to the bottom back 200, and when the seat back 300 needs to be folded, the seat back 300 is turned forward, so that the seat back 300 is turned over to the seating area of the base 100, and the space occupied by the child safety seat is reduced.
As shown in fig. 1, 4, 7 and 8, the pin assembly 400 includes a pin rod 420;
the bottom back 200 is provided with a first chute 203, the chair back 300 is provided with a second chute 302, and the pin rod 420 passes through the first chute 203 and the second chute 302;
the pin rod 420 slides along the second sliding chute 302, and the pin rod 420 has a locking station and an unlocking station relative to the bottom back 200;
in the locking position, the pin 420 is fixed relative to the back 200;
in the unlock station, the pin 420 revolves around the rotating shaft 410 and slides along the first sliding groove 203.
In one embodiment, the pin 420 is axially slidable to switch between the lock and unlock positions.
In the present embodiment, the first chute 203 includes: a first limit groove 231, an arc-shaped sliding groove 232 and a second limit groove 233;
the arc-shaped sliding groove 232 is positioned between the first limiting groove 231 and the second limiting groove 233, and the first limiting groove 231 and the second limiting groove 233 are respectively communicated with the arc-shaped sliding groove 232;
the arc-shaped sliding groove 232 is coaxial with the first shaft hole 202, and the first limiting groove 231 and the second limiting groove 233 extend along the radial direction of the first shaft hole 202 respectively.
When the work station is switched, the pin rod 420 slides along the second sliding groove 302, so that the pin rod 420 can enter the arc-shaped sliding groove 232, or slide from the arc-shaped sliding groove 232 into the first limiting groove 231 or the second limiting groove 233.
When the pin rod 420 enters the arc-shaped sliding groove 232, the pin rod 420 slides along the arc-shaped sliding groove 232, and the pin rod 420 rotates about the rotating shaft 410, so that the chair back 300 can be flipped about the rotating shaft 410 relative to the bottom back 200.
When the pin rod 420 slides into the first limiting groove 231, the first limiting groove 231 limits the pin rod 420, so that the pin rod 420 cannot return to the arc-shaped sliding groove 232, and the chair back 300 is kept in the folded state.
When the pin rod 420 slides into the second limiting groove 233, the second limiting groove 233 limits the pin rod 420, so that the pin rod 420 cannot return to the arc-shaped sliding groove 232, and the chair back 300 is maintained in the upright state.
It should be noted that the seating area is located in front of the seat back 300, the direction of the seat back 300 departing from the seating area is the rear direction, the arc-shaped sliding groove 232 extends from the lower side of the first shaft hole 202 to the rear side of the first shaft hole 202, and the central angle corresponding to the arc-shaped sliding groove 232 is 80-90 °. The first stopper groove 231 extends rearward from one end of the communicating arc-shaped sliding groove 232, and the second stopper groove 233 extends downward from one end of the communicating arc-shaped sliding groove 232. When the pin rod 420 is positioned in the second limit groove 233, the chair back 300 is maintained in the upright state; when the unlocking piece 500 is lifted, the unlocking piece 500 can drive the pin rod 420 to move into the arc-shaped sliding groove 232, at the moment, the pin rod 420 can slide along the arc-shaped sliding groove 232, and the chair back 300 can be turned forwards from the vertical state to the folded state; when the chair back 300 is folded, the lock release member 500 can drive the pin rod 420 to slide from the arc-shaped sliding slot 232 into the first limiting slot 231. When the pin rod 420 is located in the first limiting groove 231 or the second limiting groove 233, the pin rod 420 cannot rotate around the rotating shaft 410, thereby achieving the locking of the state of the chair back 300. In addition, a spring is installed between the backrest 300 and the unlocking member 500, the spring has a tendency of driving the unlocking member 500 and moving the pin rod 420 in a direction away from the first shaft hole 202, when the backrest 300 reaches a folded state, the pin rod 420 slides into the first limiting groove 231; when the chair back 300 reaches the standing state, the pin rod 420 slides into the second limit groove 233, thereby achieving automatic locking of the state of the chair back 300.
As shown in fig. 1, 7, 8 and 9, the child safety seat further includes a release 500, and the release 500 is connected to the pin 420.
The latch lever 420 is moved by the release 500, so that the latch lever 420 slides along the second sliding groove 302, and the latch lever 420 is switched between the locking position and the unlocking position. The release 500 is provided with a pin shaft hole 502, and the pin rod 420 passes through the pin shaft hole 502, so that the pin rod 420 can move along with the release 500 and the pin rod 420 can slide along the first sliding groove 203.
Further, the release member 500 is provided with a third sliding slot 501, the third sliding slot 501 and the second sliding slot 302 extend in the same direction, and the rotating shaft 410 passes through the third sliding slot 501.
When the release 500 is operated to move relative to the rotation shaft 410, the rotation shaft 410 may restrict the release 500, so that the release 500 can smoothly slide in the extending direction of the third sliding slot 501.
As shown in fig. 1, 7 and 8, the bottom back 200 is provided with a slot 204, the chair back 300 is provided with a plug connector 303, the second shaft hole 301 and the second sliding groove 302 are both arranged on the plug connector 303, and the plug connector 303 is installed in the slot 204.
Specifically, the plug-in connector 303 is installed in the slot 204, so that the chair back 300 is fixed relative to the bottom back 200 in the axial direction of the pin shaft assembly 400, which not only makes the structure compact, but also improves the stability of the chair back 300.
As shown in fig. 1, 7, 8 and 9, the release 500 has a tab portion 510, and the tab portion 510 is inserted into the slot 204.
When the plug-in unit 303 is installed in the slot 204, a clearance groove is formed between the plug-in unit 303 and the inner wall of the slot 204, and the plug-in unit 510 is inserted into the clearance groove, thereby making the connection of the back 200, the back 300 and the release 500 compact. Moreover, the insertion piece portion 510 can smoothly slide in a clearance groove formed between the insertion piece 303 and the insertion groove 204, and the insertion piece portion 510 can be prevented from loosening along the axial direction of the pin shaft assembly 400, so that the structural stability of the child safety seat is improved.
