[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-7 As shown, the utility model provides a headrest adjustment mechanism for a baby carrier, the carrier comprising a seat body 1 and a backrest 2 arranged on the seat body 1, the backrest 2 being movably provided with a headrest 3, the carrier headrest adjustment mechanism 4 comprising a plurality of adjustment locks 41 arranged at intervals on the backrest 2 and an adjustment lock 42 movably provided on the headrest 3 and locked with the corresponding adjustment locks 41; an unlocking handle 5 is movably provided on the headrest 3, the unlocking handle 5 has a first unlocking movement direction and a second unlocking movement direction opposite to the first unlocking movement direction, an unlocking linkage mechanism 6 is provided between the unlocking handle 5 and the adjustment lock 42, the unlocking linkage mechanism 6 is configured to be able to link the corresponding unlocking action of the adjustment lock 42 when the unlocking handle 5 is operated to move in the first unlocking movement direction or the second unlocking movement direction. The utility model is provided with an unlocking linkage mechanism between the unlocking handle and the adjusting lock piece, and the unlocking linkage mechanism can be linked to the corresponding unlocking action of the adjusting lock piece during the movement of the unlocking handle relative to the headrest in the first unlocking movement direction or the second unlocking movement direction. The technical scheme designed in this way can meet the operation and use of users with different operating habits, and provides convenience for their behavioral habits. Therefore, the utility model has the characteristics of reasonable structural design, practicality, convenient operation and personalized satisfaction; in addition, the height of the headrest part can be adjusted through the headrest adjustment mechanism of the basket to adapt to young children of different heights, while meeting the installation and use of different headrest parts and personalized customization.

[0031] like Figure 4 , 5As shown, the unlocking linkage mechanism 6 includes two unlocking inclined grooves 61 provided on the unlocking handle 5 or the adjusting lock 42 and an unlocking link 62 provided on the adjusting lock 42 or the unlocking handle 5 and can be placed in the unlocking inclined grooves 61. The two unlocking inclined grooves 61 are arranged in a V shape and the proximal ends are connected. When the adjusting lock 42 is locked and matched with the adjusting lock 41, the unlocking link 62 is at the proximal end position of the two unlocking inclined grooves 61. When the unlocking handle 5 is operated to slide upward or downward relative to the headrest part 3, the corresponding unlocking inclined groove 61 cooperates with the unlocking connecting rod 62 to drive the adjusting lock 42 to slide to the side away from the adjusting lock 41 and separate from the adjusting lock 41, thereby releasing the locked state of the headrest part 3 relative to the backrest part 2. Then, when the headrest part 3 is adjusted upward or downward to the desired position relative to the backrest part 2, the force applied to the unlocking handle 5 is cancelled, and the adjusting lock 42 is locked and cooperated with the corresponding adjusting lock 41 under the elastic reset force of the lock reset member 43, thereby locking the headrest part 3 relative to the backrest part 2. At the same time, the lock reset member 43 can also drive the unlocking handle 5 to slide and reset accordingly through the unlocking inclined groove 61 and the unlocking connecting rod 62, thereby simplifying the structure and making the design reasonable.

[0032] In other embodiments, a handle restoring member is provided between the unlocking handle 5 and the headrest portion 3 to drive the unlocking handle 5 to elastically return to its original position.

[0033] like Figure 4 , 5 As shown, for the convenience of resetting, the headrest adjustment mechanism 4 of the baby carrier also includes a lock reset member 43 disposed between the adjustment lock member 42 and the headrest portion 3 for driving the adjustment lock member 42 to elastically reset. The lock reset member 43 can ensure that the adjustment lock member 42 maintains a locking fit with the adjustment lock portion 41 or maintains a movement tendency to slide toward the side of the adjustment lock portion 41, thereby ensuring reliable locking. The lock reset member 43 can be a tension spring or a compression spring, etc.

[0034] like Figure 4 , 5 As shown, the headrest portion 3 is provided with a guide groove 31 for guiding the movement path of the adjustment lock 42, which can ensure that the adjustment lock 42 can slide stably and smoothly along the set direction, and also enable the adjustment lock 42 to smoothly lock and cooperate with the adjustment lock portion 41.

[0035] like Figure 3-5 As shown, in order to ensure smooth sliding of the headrest portion, the headrest portion 3 can be slidably arranged up and down along the backrest portion 2, and a sliding guide mechanism 7 is provided between the headrest portion 3 and the backrest portion 2. The sliding guide mechanism 7 includes a sliding groove 71 provided on the backrest portion 2 or the headrest portion 3 and a sliding block 72 correspondingly provided on the headrest portion 3 or the backrest portion 2 and slidably placed in the sliding groove 71.

[0036] In order to reduce the number of assembly steps and lower the manufacturing cost, the seat body 1, the backrest 2, the headrest 3 and the unlocking handle 5 are respectively integrally formed by injection molding.

[0037] like Figure 6 , 7 As shown, in order to lie comfortably and conveniently, the backrest 2 is rotatably connected to the seat body 1, and a backrest adjustment mechanism 8 for adjusting the inclination angle of the backrest 2 relative to the seat body 1 is provided between the backrest 2 and the seat body 1. The backrest adjustment mechanism 8 includes a plurality of backrest adjustment lock holes 81 provided on the seat body 1 at intervals with the rotation axis between the backrest 2 and the seat body 1 as the center, and a backrest adjustment lock rod 82 slidably provided on the backrest 2 and locked with the corresponding backrest adjustment lock holes 81.

[0038] like Figure 7 As shown, an unlocking linkage frame 9 is movably and elastically resettable on the backrest 2, and an unlocking linkage assembly 10 is provided between the unlocking linkage frame 9 and the corresponding backrest adjustment lock rod 82, and the unlocking linkage assembly 10 includes an unlocking linkage inclined groove 101 provided on the unlocking linkage frame 9 or the backrest adjustment lock rod 82 and an unlocking linkage rod 102 correspondingly provided on the backrest adjustment lock rod 82 or the unlocking linkage frame 9 and movably placed in the unlocking linkage inclined groove 101. The utility model can simultaneously and synchronously link the corresponding unlocking actions of several backrest adjustment lock rods 82 through the cooperation of the unlocking linkage frame and the corresponding unlocking linkage assembly, so that the user only needs one operation to link the unlocking actions of several backrest adjustment lock rods 82, which is convenient for the user to operate; at the same time, it can also simplify the structure and improve the market competitiveness of the product.

[0039] like Figure 1 As shown, the seat body 1 is provided with a seat portion 11, and the seat portion 11 is slidably and rotatably connected to the seat body 1, and the rear end of the seat portion 11 is rotatably connected to the lower end of the backrest 2. When the infant needs to lie down and rest in the carrier, the backrest adjustment mechanism is operated to adjust the lower part of the backrest to rotate forward and upward relative to the seat body. During the rotation of the backrest, the front part of the seat slides forward relative to the seat body under the action of the backrest, and the rear part of the seat rotates forward and upward with the lower part of the backrest, so that the angle between the seat and the backrest gradually increases, so that the backrest can better contact with the infant's back, giving the infant good comfort, and conforming to the characteristics of ergonomic design.

[0040] like Figure 1 As shown, the seat body 1 or the seat portion 11 is provided with a sliding groove 111 extending along the front-rear direction of the seat body 1 and a sliding rod 112 correspondingly provided on the seat portion 11 or the seat body 1 and slidably placed in the sliding groove 111 .
