The working principle is as follows:
1. when the child stroller is in normal use, including a locking state and a gear shifting process, in both cases, the armrest joint 304 is always in a locking state (the armrest joint 304 is not rotatable) because the armrest moving plate 303 is away from the armrest joint 304 and abuts against the rotating joint 302 under the action of the armrest compression spring 305, and the moving plate positioning column 3031 penetrates through the rotating joint 302 and then is inserted into the connecting joint positioning groove 3013.
1-1, locked state: the backrest assembly 4 is located in one of three gears, referring to fig. 4, the unlocking piece 306 is pushed out by the unlocking compression spring 308 to be away from the rotating joint 302, the unlocking piece 306 is located at the locking position, at this time, the first fixing column 3061 is located in the groove of the connecting joint clamping groove 3012, the second fixing column 3062 is located in the groove of the armrest movable plate clamping groove 3032, the rotating joint 302 and the base connecting joint 301 are locked relatively, relative rotation cannot occur, and the backrest assembly 4 is located at the locking state.
1-2, a gear shifting process: when the backrest module 4 is shifted from one gear to another gear, unlocking and locking are required. Referring to fig. 6, the adjusting buckle 5 is pulled, the unlocking steel wire 307 drives the unlocking sheet 306 to compress and unlock the compression spring 308, the unlocking sheet 306 slides towards the rotating joint 302 in the rotating joint sliding groove 3021, at this time, the unlocking sheet 306 is in an unlocking position, meanwhile, the first fixing column 3061 is disengaged from the groove of the joint clamping groove 3012, the second fixing column 3062 is disengaged from the groove of the armrest movable tray clamping groove 3032, the rotating joint 302 and the base connecting joint 301 are unlocked and can rotate relatively, the backrest assembly 4 is in an unlocking state, when the backrest assembly 4 is pushed to rotate to a required gear, the adjusting buckle 5 is released, the unlocking compression spring 308 pushes the unlocking sheet 306 out to be far away from the rotating joint 302, the unlocking sheet 306 is in a locking position, at this time, the first fixing column 3061 is located in the groove of the joint clamping groove 3012, the second fixing column 3062 is located in the groove of the armrest movable tray clamping groove 3032, the rotating joint 302, relative rotation is not allowed, i.e., the backrest module 4 is locked, and the backrest module is shifted.
2. Folding process of the baby stroller: the adjusting buckle 5 is pulled in the locking state of 1-1, the unlocking steel wire 307 drives the unlocking sheet 306 to compress and unlock the compression spring 308, the unlocking sheet 306 slides towards the rotating joint 302 in the rotating joint sliding groove 3021, at this time, the unlocking sheet 306 is in the unlocking position, the first fixing column 3061 is separated from the groove of the joint clamping groove 3012, the second fixing column 3062 is separated from the groove of the armrest movable tray clamping groove 3032, the rotating joint 302 and the base connecting joint 301 are unlocked, the backrest assembly 4 is pushed to enable the rotating joint 302 to rotate, at this time, the end surface of the second fixing column 3062 moves to the surface of the armrest movable tray 303 along the movable tray guiding inclined groove 3033, the armrest movable tray 303 moves towards the armrest joint 304 to compress the armrest compression spring 305, the movable tray positioning column 3031 is separated from the joint positioning groove 3013, the armrest joint 304 is unlocked, and the armrest joint 304 and the base connecting joint 301 can, because the end surface of the second fixed column 3062 abuts against the surface of the armrest movable disk 303 and friction force exists between the two, the rotating joint 302 drives the armrest joint 304 to approach the base connecting joint 301 in the folding and rotating process, and finally the folding is performed as shown in fig. 7.
3. Unfolding process of the child stroller: when the child stroller is unfolded from the folded state, the backrest assembly 4 is unfolded, the rotating joint 302 rotates (opposite to the rotating direction in the armrest assembly 2), because the armrest movable disk 303 can only move axially in the armrest joint 304, and relative rotation cannot occur between the armrest joint 304 and the armrest movable disk 303, under the action of the surface friction between the end surface of the second fixed column 3062 and the armrest movable disk 303, the armrest joint 304 is driven by the armrest movable disk 303 to unfold around the base connecting joint 301 together, until the connecting joint positioning block 3011 abuts against the armrest joint positioning block 3041, the armrest joint 304 cannot rotate continuously, that is, the armrest movable disk 303 cannot rotate, the backrest assembly 4 continues to rotate, after the surface friction between the end surface of the second fixed column 3062 and the armrest movable disk 303 is overcome, the end surface of the second fixed column 3062 enters the movable disk clamping groove 3032 along the movable disk guiding inclined groove 3033, under the action of the armrest compression spring 305, the armrest movable disc 303 is far away from the armrest joint 304 and abuts against the rotary joint 302, at this time, the movable disc positioning column 3031 penetrates through the rotary joint 302 and then is inserted into the joint positioning groove 3013, the armrest joint 304 is in a locked state, after the backrest component 4 rotates to a proper gear, the adjusting buckle 5 is loosened, under the action of the unlocking compression spring 308, the unlocking compression spring 308 pushes the unlocking sheet 306 out to be far away from the rotary joint 302, the unlocking sheet 306 is in a locked position, at this time, the first fixing column 3061 is located in the groove of the joint clamping groove 3012, the second fixing column 3062 is located in the groove of the armrest movable disc clamping groove 3032, the rotary joint 302 and the base connecting joint 301 are locked relatively, relative rotation cannot occur, namely, the backrest component 4 is in a locked state, and the backrest component 4 is completely unfolded and locked.
In the above embodiments, the present invention has been described only by way of example, but various modifications may be made by those skilled in the art after reading the present patent application without departing from the spirit and scope of the invention.
