DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, an adjustable child carrier includes: a backrest seat 100, a left baffle 200, a right baffle 300 and an adjustment component, wherein the backrest seat 100, the left baffle 200 and the right baffle 300 are surrounded to form a storage space for accommodating a child, and as the left baffle 200 and the right baffle 300 move, the storage space can be enlarged or reduced, thereby achieving the purpose of adjustment.

[0035] The backrest seat 100 is provided with a accommodating cavity (not shown in the figure), a left slot (not shown in the figure) and a right slot (not shown in the figure), and the left slot and the right slot are respectively connected to the two sides of the accommodating cavity; preferably, the backrest seat 100 is provided with an accommodating cavity inside, and the left slot and the right slot are respectively provided on both sides thereof.

[0036] It is important to note here that, because the left adjustment block 210 and the right adjustment block 310 need to be inserted into the backrest 100, there must be a left slot and a right slot in the form of an open or strip-shaped hole on both sides of the backrest 100. Otherwise, the left adjustment block 210 and the right adjustment block 310 cannot move relative to the backrest 100 and cannot be inserted into the accommodating cavity. Moreover, the backrest 100 is not a solid structure, so the accommodating cavity is a hollow cavity or spatial structure in the backrest 100, which is used to accommodate the gear 500 and a part of the left adjustment block 210 and the right adjustment block 310.

[0037] The left baffle 200 is movably disposed on one side of the backrest 100 . The left baffle 200 is provided with a left adjustment block 210 . The left adjustment block 210 passes through the left slot and is inserted into the accommodating cavity.

[0038] Preferably, the left baffle 200 is an L-shaped structure and is located on the left side of the backrest seat 100. It can move toward the accommodating cavity through the left slot, or it can move outward. The left adjustment block 210 is inserted into the accommodating cavity, and the left adjustment block 210 can drive the left baffle 200 to move left or right.

[0039] The right baffle 300 is movably disposed on the other side of the backrest 100 . The right baffle 300 is provided with a right adjustment block 310 . The right adjustment block 310 passes through the right slot and is inserted into the accommodating cavity.

[0040] Preferably, the right baffle 300 is located on the right side of the backrest 100 , and its structure is similar to that of the left baffle 200 . The right baffle 300 can be driven to move leftward or rightward by the right adjustment block 310 .

[0041] The adjustment component is linked to the left adjustment block 210 and the right adjustment block 310 , and the adjustment component can drive the left baffle 200 and the right baffle 300 to move through the left adjustment block 210 and the right adjustment block 310 .

[0042] It should be noted here that the left baffle 200 and the right baffle 300 can move synchronously, that is, the adjustment component can drive the left adjustment block 210 and the right adjustment block 310 to move. Since the left adjustment block 210 and the left baffle 200 are fixed, and the right adjustment block 310 and the right baffle 300 are also fixed, the adjustment component can simultaneously drive the left baffle 200 to move toward the left and the right baffle 300 to move toward the right, so that the left baffle 200 and the right baffle 300 move toward each other, and the space in the child's backpack becomes larger; and the adjustment component can also simultaneously drive the left baffle 200 to move toward the right and the right baffle 300 to move toward the left, so that the left baffle 200 and the right baffle 300 are close to each other, and the space in the child's backpack becomes smaller.

[0043] Therefore, this adjustable structure can adapt to children of different body shapes. In actual use, the left baffle 200 and the right baffle 300 can be opened or closed by adjusting the components, thereby adjusting the size of the backpack.

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, on the basis of the above embodiment, the left adjustment block 210 is provided with a first strip groove 220 and a first transmission rack 230, and the first transmission rack 230 is arranged in the first strip groove 220. Preferably, the left adjustment block 210 is actually an L-shaped metal plate or a bracket structure, one end of which is inserted into the left stopper, and the other end is provided with a first strip groove 220, and a first transmission rack 230 is provided at the top of the first strip groove 220.

[0045] The right adjustment block 310 is provided with a second strip groove 320 and a second transmission rack 330, and the second transmission rack 330 is arranged in the second strip groove 320. Preferably, the right adjustment block 310 is actually an L-shaped metal plate or a bracket structure, one end of which is inserted into the right stopper, and the other end is provided with a second strip groove 320, and a second transmission rack 330 is provided at the bottom of the second strip groove 320.

[0046] The adjustment assembly is inserted into the first strip groove 220 and the second strip groove 320 and is linked to the first transmission rack 230 and the second transmission rack 330 .

[0047] Preferably, the first strip groove 220 and the second strip groove 320 partially overlap, and the adjustment component can pass through the first strip groove 220 and the second strip groove 320 and can also move within the first strip groove 220 and the second strip groove 320. At this time, the adjustment component can drive the left adjustment block 210 and the right adjustment block 310 to move through the first transmission rack 230 and the second transmission rack 330.

[0048] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, based on the above embodiment, the adjustment component includes a rotating shaft 400 and a gear 500, the rotating shaft 400 is connected to the backrest seat 100, the gear 500 is connected to the rotating shaft 400, and the gear 500 is located in the first strip groove 220 and the second strip groove 320, and the gear 500 is engaged with the first transmission rack 230 and the second transmission rack 330.

[0049] Preferably, the adjustment component is actually adjusted by the gear 500. In the actual structure, the gear 500 is connected to the rotating shaft 400, and the rotating shaft 400 is connected to the backrest 100. The gear 500 passes through the first strip groove 220 and the second strip groove 320, so when the gear 500 rotates, it simultaneously drives the first transmission rack 230 and the second transmission rack 330, so that the left adjustment block 210 and the right adjustment block 310 can move toward each other on both sides, or make the left adjustment block 210 and the right adjustment block 310 approach each other, so that the position of the left baffle 200 and the right baffle 300 can be changed, thereby adjusting the size of the backpack.

[0050] It is important to note here that, in the actual structure, the first transmission rack 230 is located above the first strip groove 220, and the second transmission rack 330 is located below the second strip groove 320, so the first transmission rack 230 is engaged with the upper part of the gear 500, and the second transmission rack 330 is engaged with the lower part of the gear 500. When the gear 500 rotates, the left adjustment block 210 and the right adjustment block 310 can move in opposite directions.

[0051] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, on the basis of the above embodiment, it also includes a pillow seat 700, and the backrest seat 100 is also provided with an upper slot (not shown in the figure), the pillow seat 700 is movably connected to the backrest seat 100, and the pillow seat 700 is provided with an upper adjustment block 710, and the upper adjustment block 710 is inserted into the accommodating cavity through the upper slot and is linked to the adjustment component.

[0052] Preferably, the pillow seat 700 can be adjusted up and down. Specifically, the upper adjustment block 710 is inserted into the accommodating cavity from the upper slot, and the adjustment assembly can drive the backrest seat 100 to move up and down, thereby adjusting the height of the pillow seat 700.

[0053] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, based on the above embodiment, the upper adjustment block 710 is provided with a third strip groove 720 and a third transmission rack 730, the third transmission rack 730 is provided in the third strip groove 720, and the gear 500 penetrates into the third strip groove 720 and engages with the third transmission rack 730.

[0054] Preferably, the working principle of the upper adjustment block 710 is similar to that of the left adjustment block 210 or the right adjustment block 310. The gear 500 can move in the third strip groove 720, and when the gear 500 rotates, the upper adjustment block 710 can be driven up and down through the third transmission rack 730.

[0055] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, based on the above embodiment, the upper adjustment block 710 is linked to the left adjustment block 210 and the right adjustment block 310 through the gear 500, and when the pillow seat 700 moves along the upper slot, it drives the left baffle 200 and the right baffle 300 to move.

[0056] It should be noted here that, during the actual adjustment process, if the space of the backpack needs to be expanded, the gear 500 is rotated so that the gear 500 drives the left baffle 200 and the right baffle 300 to move toward the left and right sides respectively, and the pillow seat 700 moves upward; when the space of the backpack needs to be reduced, the gear 500 can be rotated in the opposite direction so that the left baffle 200 and the right baffle 300 are close to each other, and the pillow seat 700 moves downward.

[0057] In the actual structure, since the upper adjustment block 710, the left adjustment block 210 and the right adjustment block 310 are linked together through the gear 500, as long as one adjustment block moves, the other two adjustment blocks can be driven to move through the gear 500.

[0058] Therefore, during the actual adjustment process, the gear 500 can be driven to rotate by pulling the pillow seat 700, thereby driving the left baffle 200 and the right baffle 300 to move. More specifically, the pillow seat 700 can be pulled upward to make the left baffle 200 and the right baffle 300 move toward both sides respectively, thereby increasing the space of the backpack. The pillow seat 700 can also be pushed downward to make the left baffle 200 and the right baffle 300 closer, thereby reducing the space of the backpack.

[0059] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, based on the above embodiment, the adjustment component also includes a knob 600, the rotating shaft 400 is passed through the backrest seat 100, one end of the rotating shaft 400 extends into the accommodating cavity and is connected to the gear 500, and the other end of the rotating shaft 400 is connected to the knob 600.

[0060] Preferably, the size of the backpack can be adjusted by actively driving the rotating shaft 400 to drive the gear 500 to rotate. Specifically, the knob 600 is located on the backrest seat 100 or outside the backrest seat 100. The user can rotate the rotating shaft 400 by the knob 600 to rotate the gear 500, thereby driving the pillow seat 700, the left baffle 200 and the right baffle 300 to move.

[0061] like Figure 1 、 Figure 5 As shown, based on the above embodiment, the backrest 100 is further formed with a back portion 110 adapted to the child seat for a vehicle. Preferably, the child carrier is a dual-purpose carrier that can be used for carrying or lifting, and can also be placed on a child safety seat as a lining.

[0062] During actual use, the child carrier can be carried on the body or placed on a child seat. Since the backrest has a back portion 110 behind it, the back portion 110 can fit on the safety seat, so that the child in the carrier can be placed directly on the child safety seat.

[0063] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, on the basis of the above embodiment, it also includes a support base 120, the support base 120 is connected to the back seat 100, the support base 120 is connected to a first restraint belt 130 and a second restraint belt 140, the first restraint belt 130 is connected to the left baffle 200 and the back seat 100, and the second restraint belt 140 is connected to the right baffle 300 and the back seat 100.

[0064] Preferably, the support base 120 is actually a seat cushion, and the first restraint belt 130 and the second restraint belt 140 can restrain the child in the child backpack to prevent the child from falling. In addition, since the first restraint belt 130 and the second restraint belt 140 are respectively connected to the left baffle 200 and the right baffle 300, when the left baffle 200 and the right baffle 300 are adjusted, the first restraint belt 130 and the second restraint belt 140 can be adjusted along with the adjustment of the two, ensuring convenience and reliability during use.

[0065] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 As shown, based on the above embodiment, the backrest seat 100 is further provided with two sets of connecting parts, which include an upper connecting buckle 150 for fixing the upper end of the shoulder strap and a lower connecting buckle 160 for fixing the lower end of the shoulder strap.

[0066] The pillow seat 700 is the pillow of the backpack. The backpack can be used in a variety of ways. The user can carry it or carry it on his back. The two sets of connecting parts are located on both sides of the back seat 100, and the two ends of the strap are respectively connected to the upper connecting buckle 150 and the lower connecting buckle 160, so that the strap can be easily installed on the back seat 100.

[0067] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship and movement status of various components under a specific posture (as shown in the accompanying drawings).
