Working principle: as shown in fig. 1 and 2, when the stroller is in a use state, the lock pin in the positioning sleeve is inserted into the lock hole of the push rod through the positioning sleeve, so that the relative position between the positioning sleeve and the push rod is locked, at this time, the push rod 8, the rear stay 52 and the rear bracket form a triangular support device, the rear bracket, the front bracket and the pull arm 51 form a triangular support device, the supporting effect on the cushion and the backrest is achieved, and the stroller is in a normal pushing use state.
As shown in fig. 9 and 10, when the stroller needs to be folded, the user lifts the locking pin 97 upward, the bottom of the locking pin 97 is separated from the stop table 98 on the top of the lock pin 91, and the locking pin is released from the stop of the backward movement. Then, the unlocking button 85 positioned at the tail part of the handle rod 81 is pressed, the unlocking button 85 pushes the linkage seat 87 to move downwards through the driving rod 86, and the first driving groove on the linkage seat and the second driving groove on the driving seat are extruded by the inner guide rod 892 of the first driving groove. By utilizing the interaction of the first driving groove and the second driving groove, the driving seat is forced to sink downwards, the elastic bead 82 is forced to be separated from the gear hole 83 on the push rod 8, a user can downwards press the handle rod 81, when the handle rod 81 is pushed down to the right position, the push block 84 positioned on the cylindrical surface of the handle rod 81 pushes the driving column 96 to move outwards, when the driving column moves outwards, the lock pin 91 is forced to be separated from the lock hole 92, the locking between the positioning sleeve 9 and the push rod 8 is released, the positioning sleeve can slide on the push rod, and at the moment, the reset torsion spring 54 on the positioning seat 5 drives the reset seat 5 to always deflect towards the rear wheel 2, and the dead weight of the baby carrier is added, so that folding power is generated. And the back support 52 and the push rod 8 drive the backrest to topple towards the rear wheel, and the pull arm 51 pulls the front support to topple towards the rear wheel, so that the baby carrier is folded finally. Wherein, owing to reset torsion spring 54's setting for once the user presses down the handle bar and releases the locking to the position sleeve back, reset torsion spring can drive this shallow automatic folding with the help of bassinet dead weight, great promotion folding convenience.
As shown in fig. 4 and 5, when the backrest in the present case is folded, the locking swing buckle 13 is pulled inwards to force the locking swing buckle to be separated from the locking groove 14 on the cylindrical surface of the lower sleeve 11, at this time, the upper sleeve 12 loses the supporting force, and under the action of the gravity of the backrest, the upper sleeve 12 moves towards the sleeve 11, so that the whole backrest swings towards the rear wheel direction, and the folded volume of the baby carrier is further reduced. In the same way, in the use process, the backrest angle can be adjusted by selecting the butt joint or the separation of the locking swing buckle 13 and the locking groove 14, so that the requirement of a user on the backrest angle can be met.
When the user needs to use the cart again, the user only needs to operate reversely, lift the handle rod upwards, force the positioning sleeve to reset by utilizing the self weight of the cart, reinsert the lock pin 91 into the lock hole 92 for locking, and the locking swing buckle 13 and the locking groove 14 are buckled again. Compared with the prior art, the cart adopts the hard support cushion and the backrest, so that the cart is more comfortable to sit compared with the traditional flexible seat. Meanwhile, due to the unique folding structure, one-key folding can be realized, and folding convenience is improved. In addition, after the cart is folded, the rear wheels and the headrest can be supported on the ground to stand, so that the cart is convenient for a user to store, and can be widely popularized and used.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
