Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to Chinese Patent Application No. 2022101629481, filed on February 22, 2022, the contents of which are hereby incorporated by reference in their entirety. TECHNICAL FIELD

[0002] The present disclosure relates to child carriers, in particular to a child carrier having a movable backrest frame. BACKGROUND

[0003] Conventional child carriers currently on the market, such as strollers, include a backrest with a headrest. The backrest can be rotated relative to a frame of the child carrier into a tilted and horizontal position. The headrest is connected to an upper edge of the backrest and can be rotated relative to the backrest into a position approximately parallel or perpendicular to the backrest.

[0004] When the child is in the child carrier, the backrest can be rotated to the reclined position so that the child's back can rest against the backrest. At this time, the headrest can be adjusted so that it is approximately parallel to the backrest. When the baby needs to lie down, such as for sleeping or changing a diaper, rotating the backrest to the horizontal position allows the baby to lie more comfortably on the backrest. At the same time, rotating the headrest to a state substantially perpendicular to the backrest can provide a stopper in a direction of the child's head to prevent the child from slipping out toward the headrest. PRESENTATION OF THE INVENTION

[0005] According to various embodiments, a child carrier is provided.

[0006] A child carrier includes a main frame, a seat frame provided on the main frame, and a backrest frame. The backrest frame includes a backrest assembly capable of rotating between a vertical position and a horizontal position relative to the seat frame, a headrest assembly pivotally connected to an upper end of the backrest assembly, a coupling side member slidably connected to the backrest assembly, and an elastic member provided between the backrest assembly and the headrest assembly. An upper end of the coupling side member is pivotally connected to the headrest assembly, and a lower end of the coupling side member is connected to the seat frame by a connecting strap.

[0009] To facilitate understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. However, the present application may be implemented in many different embodiments and is not limited to the embodiments described herein. Rather, these embodiments are intended to provide a more thorough and comprehensive understanding of the public content of the present application.

[0010] It should be noted that an element described as being "attached to" or "disposed on" another element may be directly on top of the other element, or there may also be an intervening element. When an element is described as being "connected" to another element, it may be directly connected to the other element, or there may also be intervening elements. The terms "vertical," "horizontal," "top," "bottom," "left," "right," and similar expressions as used herein are for purposes of illustration only and do not represent the only embodiment.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the description of this application are for the purpose of describing particular embodiments only and are not intended to limit this application.

[0012] As described in the background, the current shortcoming of the child carrier is that rotating the headrest relative to the backrest requires an operator to operate the headrest. When the headrest is rotated from the horizontal position to the reclined position, the headrest cannot automatically return to a state substantially parallel to the backrest, which is inconvenient to use. During the backrest change, there are safety issues or situations that cause discomfort to young children. To eliminate the above-mentioned problems, it is necessary to provide a child carrier with an automatically reversible headrest.

[0013] With reference to Fig. 1, a child carrier 100 according to one embodiment includes a main frame 10, a seat frame 20, and a backrest frame 30. The seat frame 20 is attached to the main frame 10. The backrest frame 30 is pivotally attached to the seat frame 20.

[0014] The main frame 10 includes a pair of front leg bars 11, a pair of rear leg bars 12, a handle push bar 13, two armrests 15, and two auxiliary bars 16. The distal ends of the front leg bar 11 and the rear leg bar 12 are each connected to casters (not marked). The upper ends of the front leg bar 11 and the rear leg bar 12 on the same side are pivotally connected to a front end of the armrest 15 on the same side. In this embodiment, the handle push bar 13 has a substantially inverted U shape and includes two side bar portions 131 spaced apart in the left-right direction. Lower ends of the two side bar portions 131 are each pivotally connected to the two rear leg bars 12.The two auxiliary rods 16 are respectively located on an inner side of the two side rod portions 131, and an extending direction of the auxiliary rod 16 is substantially the same as that of the side rod portion 131. The lower end of the auxiliary rod 16 is pivotally connected to the lower end of the side rod portion 131, and a rear end of the armrest 15 is pivotally connected to an upper end of the auxiliary rod 16.

[0015] As in Fig. 1, the seat frame 20 includes a pair of seat support rods 21 and a seat plate 22 slidably mounted on the seat support rods 21. Specifically, the seat support rod 21 is substantially L-shaped, one end of the seat support rod 21 is pivotally connected to the front leg rod 11, and the other end of the seat support rod 21 is pivotally connected to the auxiliary rod 16. Rear ends of the seat plate 22 are respectively pivotally connected to the two auxiliary rods 16. Both sides of the seat plate 22 are provided with sleeve portions 222. The sleeve portion 222 is slidably fitted onto the seat support rod 21 and can be driven by the handle slide rod 13 to slide on the seat support rod 21.

[0016] As in the Fig. 2 to 4, the backrest frame 30 includes a backrest assembly 32, a headrest assembly 34, an elastic member 36 (see Fig. 5), a pair of coupling side members 38 and a pair of connecting seats 39.

[0017] The backrest assembly 32 includes a backrest support member 322 and two canopy attachment bases 324 attached to the backrest support member 322. The backrest support member 322 is substantially inverted U-shaped and includes two side portions 321 spaced apart in the left-right direction, and an upper portion 323 connecting the upper ends of the two side portions 321. A distal end of each side portion 321 is attached to the connecting seat 39 and can be rotated forward or backward with the connecting seat 39 relative to the seat frame 20. The headrest assembly 34 is substantially plate-shaped, with a lower end of the headrest assembly 34 being pivotally connected to the upper portion 323 of the backrest support member 322 via a hinge.

[0018] With reference to Fig. 5 and Fig. 6, the elastic member 36 is provided between the headrest assembly 34 and the backrest assembly 32. More specifically, the elastic member 36 includes two torsion spring portions 362 fitted onto the upper portion 323, and a pressing portion 364 connected between the two torsion spring portions 362 and having a substantially inverted U-shape. The pressing portion 364 abuts a front side of the headrest assembly 34, and the two torsion spring portions 362 are subjected to a torsional biasing force, so that the pressing portion 364 is biased rearward toward the headrest assembly 34 and the headrest assembly 34 is maintained in a state substantially parallel to the backrest assembly 32.

[0019] With reference to Fig. 2 and Fig. 3, each top attachment base 324 is again fixedly provided on the side portion 321, and the top attachment base 324 extends in a direction substantially perpendicular to the side portion 321. The backrest assembly 32 further includes a first top support bar 332 and a second top support bar 334. Referring to Fig. 2 and Fig. 5, the first canopy support bar 332 has a substantially inverted U shape, and both ends of the first canopy support bar 332 are pivotally connected to the outer sides of the upper ends of the two canopy attachment bases 324, respectively. A shape of the second canopy support bar 334 is similar to that of the first canopy support bar 332, and both ends of the second canopy support bar 334 are respectively attached to one side of the two canopy attachment bases 324. A canopy (not shown) of the child carrier 100 can be covered between the first canopy support bar 332 and the second canopy support bar 334, and an expanding area of ​​the canopy can be adjusted by pivoting the first canopy support bar 332.

[0020] With reference to Fig. 2 and Fig. 3, each of the coupling side members 38 is substantially a slightly arcuate hollow bar having an upper end 382 and a lower end 384. The upper ends 382 of the two coupling side members 38 are pivotally connected to the left and right edges of the headrest assembly 34, respectively. Therefore, under the tension of the coupling side member 38, the headrest assembly 34 can overcome an elastic force of the elastic member 36 and rotate relative to the upper portion 323. The lower end 384 is provided in the axial direction with an elongated sliding groove 386 extending in a direction substantially parallel to the side portion 321. A positioning pin 326 capable of sliding in the sliding groove 386 is provided on an inner side of the upper end of the top attachment base 324.In one embodiment, the positioning pin 326 is cylindrical, both ends of the sliding groove 386 are arcuate, so that when the positioning pin 326 is located at either end of the sliding groove 386, the coupling side member 38 can rotate about the positioning pin 326 at a certain angle relative to the top attachment base 324.

[0021] The two connecting seats 39 are each pivotally connected to the seat frame 20. More specifically, with reference to Fig. 3 and Fig. 4, an edge of the seat plate 22 extends vertically upward to form a pivoting portion 226, and the connecting seat 39 is pivotally connected to an inner side of the pivoting portion 226 by a pin, so that the backrest support member 322, which is fixed to the connecting seat 39, can be rotated relative to the seat frame 20. Referring to Fig. 3 and Fig. 4, the backrest assembly 32 further includes an angle adjustment mechanism 35. The angle adjustment mechanism 35 has a substantially inverted U-shape. One end of the angle adjustment mechanism 35 is movably connected to the connecting seat 39. The angle adjustment mechanism 35 is configured to adjust and fix an inclination angle of the backrest frame 30 relative to the seat frame 20, so that the backrest frame 30 can be positioned in a vertical position, a horizontal position, or any inclined position therebetween, thereby providing more application scenarios for the user.

[0022] With reference to Fig. 2 and Fig. 4, a lower end of the coupling side member 38 is further connected to the seat frame 20 by a connecting belt 40. More specifically, the lower end 384 is provided with a suspension eyelet 388, the seat plate 22 is provided with a mounting hole 224 adjacent to the connecting seat 39, and the connecting seat 39 is provided with a limiting hole 392. One end of the connecting belt 40 is attached to the suspension eyelet 388, and the other end of the connecting belt 40 extends through the limiting hole 392 and is secured in the mounting hole 224. In other embodiments, the connecting belt 40 may also be directly connected between the suspension eyelet 388 and the mounting hole 224, and in this case, the limiting hole 392 may also be omitted. The connecting belt 40 is a pliable, flexible webbing made of materials such as nylon, fabric, rubber bands, or metal chains.The connecting belt 40 has a loose state and a tight state, which are described in detail below in connection with various application scenarios.

[0023] With reference to Fig. 5 to Fig. 7, when the backrest assembly 32 is in the vertical position, the backrest assembly 32 is substantially upright with respect to the seat frame 20. At this time, the positioning pin 326 is located at the end of the sliding groove 386 adjacent to the connecting seat 39, and the connecting belt 40 is in the loose, untensioned state. The headrest assembly 34 is oriented substantially parallel to the backrest assembly 32 due to a biasing force of the elastic member 36, so that the child's body, when sitting in the child carrier 100, can lean its back against the backrest assembly 32 and its head against the headrest assembly 34.

[0024] With reference to Fig. 8 and Fig. 9, when the child seated in the child carrier 100 needs to lie down, the backrest assembly 32 can be rotated rearward by the angle adjustment mechanism 35, and the coupling side member 38 can be driven to rotate relative to the seat frame 20 into a substantially horizontal position. During this operation, the connecting belt 40 gradually changes from the loose state to the tight state and exerts a force on the coupling side member 38, so that the positioning pin 326 begins to slide toward one end of the sliding groove 386 away from the connecting seat 39, thereby allowing the coupling side member 38 to begin to slide downward relative to the canopy attachment base 324, and further drives the headrest assembly 34 to overcome the elastic force of the elastic member 36 and rotate forward relative to the upper portion 323 of the backrest support member 322.When the positioning pin 326 is positioned at the end of the sliding groove 386 away from the connecting seat 39, the headrest assembly 34 rotates to a state substantially perpendicular to the backrest assembly 32, and the torsion spring portion 362 is deformed to store an elastic restoring force. In the embodiment shown in FIG. Fig. 9, the child may lie on the backrest assembly 32 in the substantially horizontal position, while the substantially vertical headrest assembly 34 may produce a similar effect to a barrier wall, thereby preventing the child from sliding towards the head or falling out of the child carrier 100 and causing a hazard.

[0025] Similarly, when the backrest assembly 32 needs to be rotated from the horizontal position back to the vertical position, the backrest assembly 32 can be rotated forward by releasing the angle adjustment mechanism 35. The connecting strap 40 gradually transitions from the tightened state to the loosened state and stops pulling the coupling side member 38. The headrest assembly 34 causes the coupling side member 38 to slide upward through the elastic restoring force of the elastic member 36, and finally, the headrest assembly 34 returns to the state substantially parallel to the backrest assembly 32.

[0026] In summary, by designing the coupling structure between the backrest assembly 32, the headrest assembly 34, and the coupling side member 38, which cooperates with the connecting belt 40 and the elastic member 36, when the backrest assembly 32 rotates, the headrest assembly 34 can be rotated together with the backrest assembly 32. In this way, the operator only needs to operate the backrest assembly 32 to move the headrest assembly 34 to its appropriate position, which improves comfort and safety of use.

[0027] With reference to Fig. 9 and Fig.In this embodiment, since the seat plate 22 can slide relative to the seat support rod 21, when the handle push rod 13 rotates relative to the main frame 10, the seat plate 22 can move from the first position to the second position relative to the main frame 10, thereby causing the child sitting in the child carrier 100 to move, that is, a center of gravity of the entire child carrier 100 to change. In this way, the user can rotate the handle push rod 13 to adjust the center of gravity of the child carrier 100 as needed, so that the center of gravity of the child carrier 100 can move backward after a change of direction, and it is more labor-saving to push. Compared to conventional child carriers in which the backrest support member, the canopy attachment base, etc.are directly attached to the main frame, the backrest support member 322 and the canopy attachment base 324 of this embodiment are attached directly to the seat frame 20, so that a forward and backward displacement of the seat plate 22 is not impaired.
