[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 2021112231488, entitled "Child Carrier," filed on October 20, 2021, the entire contents of which are incorporated herein.

[0002] FIELD OF THE DISCLOSURE The present disclosure relates to carriers, and more particularly to child carriers. [Background technology]

[0003] Currently, some child carriers on the market, such as strollers, have the function of changing the forward direction using a handle. That is, the forward direction of the stroller can be changed by rotating the handle. Before the forward direction is changed by rotating the handle, the baby's center of gravity is close to the rear wheel. However, after the forward direction is changed by rotating the handle, the center of gravity is closer to the front wheel, i.e., the rear wheel before the forward direction is changed, which makes pushing the stroller harder and more inconvenient. Furthermore, the height of the stroller's center of gravity cannot be adjusted as needed, resulting in a poor user experience. Summary of the Invention

[0025]

[0023] Embodiments of the present invention will now be described more fully with reference to the accompanying drawings. However, various embodiments of the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Elements identified using the same or similar reference numerals refer to the same or similar elements.

[0026] When an element is referred to as being "connected" or "coupled" to another element, it will be understood that the element may be directly connected or coupled to the other element, or that intervening elements may be present. In contrast, when an element is referred to as being "directly connected" or "directly coupled" to another element, there are no intervening elements present.

[0027] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Terms such as those defined in commonly used dictionaries should be interpreted to have a meaning consistent with their meaning in the context of the relevant art, and it can be further understood that they should not be interpreted in an idealized or overly formal sense unless explicitly defined as such in this specification.

[0028] 1 and 2, according to one embodiment of the present disclosure, a child carrier 10, such as a stroller, is provided. The child carrier 10 includes a frame 100, a handle 200, and a seat support member 300. When the handle 200 is rotated, the position of the center of gravity of the child carrier 10 can be adjusted as needed, which makes it convenient for the user to push the child carrier 10 and provides a better user experience.

[0029] Specifically, as shown in FIGS. 1 to 4, the handle 200 is rotatably connected to the frame 100, and the seat support member 300 is configured to support a seat (not shown). The handle 200 can rotate relative to the frame 100 to change the movement direction of the frame 100 from a first direction D1 to a second direction D2, and simultaneously drives the seat support member 300 to move relative to the frame 100 from a first position (see FIG. 2) to a second position (see FIG. 4). The second position is located in the first direction D1 of the first position. The first direction D1 may be, for example, a horizontal leftward direction as shown in FIG. 1, and the second direction D2 may be, for example, a horizontal rightward direction as shown in FIG. 1. With respect to the second direction D2 (i.e., the movement direction after the handle 200 is rotated), the second position is located rearward of the first position. That is, when the handle 200 is rotated to change the movement direction of the frame 100 from the first direction D1 to the second direction D2, the seat support member 300 is driven to move rearward. Because the seat support member 300 is configured to support a seat, the child sitting in the seat moves as the seat support member 300 moves, i.e., the center of gravity of the entire child carrier 10 changes. In this way, the user can adjust the center of gravity of the child carrier 10 by rotating the handle 200, and as a result, the center of gravity of the child carrier 10 moves rearward after rotating the handle 200, making it easier to push the child carrier 10.

[0030] In other embodiments, the second position may be located above or below the first position. When the second position is located above the first position, the center of gravity of child carrier 10 moves upward as handle 200 is rotated. In this way, the height of a child sitting on child carrier 10 can be increased, and the child's inhalation of harmful gases such as automobile exhaust can be reduced, which is beneficial to the child's health. When the second position is located below the first position, the center of gravity of child carrier 10 moves downward as handle 200 is rotated, thereby increasing the overall stability of child carrier 10 and improving the safety performance of child carrier 10.

[0031] 5 and 6, the frame 100 includes a support rod 110, a first wheel support 120, and a second wheel support 130. Ends of the first wheel support 120 and the second wheel support 130 are connected to a first wheel 140 and a second wheel 150, respectively, and the other end of the first wheel support 120 is fixed to the other end of the second wheel support 130 to form a substantially triangular support structure. The support rod 110 is connected between the first wheel support 120 and the second wheel support 130. In this embodiment, a handle 200 is rotatably connected to the support rod 110. Of course, in other embodiments, the handle 200 may be rotatably connected to the first wheel support 120 or the second wheel support 130.

[0032] 1 to 16 , the child carrier 10 further includes a first linkage assembly 400, a rotating shaft 500, a fixed plate 600, and a reinforcing plate 700. The seat support member 300 is slidably disposed on the support rod 110, and the handle 200 is rotated to drive the seat support member 300 to move along the support rod 110. Specifically, when the handle 200 is rotated, the seat support member 300 is driven to move along the support rod 110 by the first linkage assembly 400. In this embodiment, the seat support member 300 is a sliding sleeve that can be slidably fitted onto the support rod 110. The child carrier 10 further includes a plurality of pulleys (not labeled, but shown in FIG. 2 ) positioned on the seat support member 300 and abutting against the support rod 110. In this way, the sliding friction between the seat support member 300 and the support rod 110 can be reduced, thereby allowing the seat support member 300 to move more smoothly along the support rod 110. In this embodiment, four pulleys are provided, two pulleys abutting the upper side of the support rod 110 and the other two pulleys abutting the lower side of the support rod 110. Of course, in other embodiments, the number and arrangement of pulleys can also be changed as needed.

[0033] 7 and 8, the first linkage assembly 400 may include a rotating member 410 and a driving member 420. As shown in Fig. 8, the rotating member 410 is formed in a substantially elliptical disk shape, and the driving member 420 is formed in a substantially arc shape. In this embodiment, both the rotating member 410 and the driving member 420 are positioned above the seat support member 300, and the center of the arc shape of the driving member 420 is positioned below the driving member 420. Of course, in other embodiments, both the rotating member 410 and the driving member 420 may be positioned below the seat support member 300.

[0034] In this embodiment, as shown in FIG. 6 , the support rod 110 includes a first rod 111 and a second rod 112 that are connected to each other. The first rod 111 is disposed horizontally, and the second rod 112 forms an angle, for example, an obtuse angle, with the first rod 111. The handle 200 is rotatably connected to the second rod 112. One end of a rotating member 410 is fixed to the handle 200, the other end of the rotating member 410 is rotatably connected to one end of a driving member 420, and the other end of the driving member 420 is rotatably connected to the seat support member 300. In this manner, as shown in FIGS. 13 and 14 , the rotating member 410, the driving member 420, and the seat support member 300, which are rotatably connected to each other and can move, form a structure similar to a link. When the handle 200 is rotated in a third direction D3, such as counterclockwise, the rotating member 410 and the driving member 420 rotate under the pulling force of the handle 200, thereby driving the seat support member 300 to move along the support rod 110. move Since the handle 200 is moved in accordance with the direction of travel and is always on the same side as the rear wheel in the direction of travel, the seat support member 300 can be automatically driven away from the direction of travel along the support rod 110 as the handle 200 is rotated, and the center of gravity of the entire child carrier 10 moves rearward, making it easier to push the child carrier 100 after the handle 200 is rotated to change the direction of travel of the child carrier 10.

[0035] 5, 9, and 10, the rotating shaft 500 is fixed to the handle 200 and extends through the frame 100 so that the handle 200 is rotatably connected to the frame 100. One end of the rotating member 410 is fixed to the rotating shaft 500. In this way, the handle 200 is rotatably connected to the frame 100 via the rotating shaft 500, and when the handle 200 is rotated, the rotating member 410 can be rotationally driven via the rotating shaft 500, thereby driving the seat support member 300 to move.

[0036] 5, 9, and 10, the handle 200 includes a handle holder 210 located at an end of the handle 200. The rotating shaft 500 is fixed to the handle holder 210, and a fixing plate 600 can strengthen the connection between the rotating shaft 500 and the handle holder 210. Specifically, the fixing plate 600 may be in the shape of a partial gear, and the rotating shaft 500 extends through a central hole of the fixing plate 600 and is fixed to the central hole, and an edge of the fixing plate 600 is fixed to the handle holder 210. In this embodiment, the inner wall of the central hole of the fixing plate 600 is welded to the rotating shaft 500, and an edge of the fixing plate 600 is welded to the handle holder 210. Of course, in other embodiments, other connection modes may be used, which are not limited herein.

[0037] 15 and 16, a reinforcing plate 700 covers the side surface of the rotating member 410 to ensure the strength of the rotating member 410. In this embodiment, the reinforcing plate 700 is an iron plate that covers the inner surface of the rotating member 410. Of course, in other embodiments, the reinforcing plate 700 may be made of other materials or may be replaced with another structure.

[0038] 17 to 25, the child carrier 10 further includes a second linkage assembly 800 and a rotating shaft 500. The seat support member 300 is connected to the support rod 110 via the second linkage assembly 800, and the handle 200 is rotated to drive the seat support member 300 to move relative to the support rod 110. In this manner, by rotating the handle 200, the center of gravity of the child carrier 10 can be changed.

[0039] Specifically, as shown in FIGS. 22 to 26 , the second linkage assembly 800 may include a first linkage rod 810 and a second linkage rod 820. One end of the first linkage rod 810 is fixed to the handle 200, and the other end of the first linkage rod 810 is rotatably connected to one end of a seat support member 300. The other end of the seat support member 300 is rotatably connected to one end of a second linkage rod 820, and the other end of the second linkage rod 820 is rotatably connected to a support rod 110. The first linkage rod 810, the seat support member 300, the second linkage rod 820, and the support rod 110 are sequentially connected to form a deformable quadrilateral structure. In this embodiment, the first linkage rod 810, the seat support member 300, and the second linkage rod 820 are all positioned above the support rod 110. Of course, in other embodiments, the first linkage rod 810, the seat support member 300, and the second linkage rod 820 may all be located below the support rod 110. In this way, on the one hand, as shown in Figures 17 and 18, when the handle 200 is rotated in the third direction D3, the first linkage rod 810, the seat support member 300, and the second linkage rod 820 can rotate under the pulling force of the handle 200. When the handle 200 is driven, the seat support member 300 is always in contact with the handle 200. moveSince the handle 200 is moved in accordance with the direction of travel and the handle 200 is always on the same side as the rear wheels in the direction of travel, the seat support member 300 can be automatically driven away from the direction of travel along the support rods 110 as the handle 200 is rotated, and the center of gravity of the entire child carrier 10 moves rearward, making it easier to push the child carrier 100 after rotating the handle 200 to change the direction of travel of the child carrier 10. Meanwhile, as shown in FIGS. 18 and 19 , the first linkage rod 810, the seat support member 300, the second linkage rod 820, and the support rods 110 form a deformable quadrilateral structure, so that the distance between the seat support member 300 and the support rods 110 can also be changed while the handle 200 is being rotated. That is, the height of the seat support member 300 is changed, and thereby the height of the center of gravity of the child carrier 10 is changed. In this way, the user can adjust the height of the center of gravity of the child carrier 10 as needed by rotating the handle 200.

[0040] 21 , 23 , and 25 , the rotating shaft 500 is fixed to the handle 200 and extends through the frame 100 so that the handle 200 is rotatably connected to the frame 100. One end of a first linkage rod 810 is fixed to the rotating shaft 500. In this way, the handle 200 is rotatably connected to the frame 100 via the rotating shaft 500, and when the handle 200 is rotated, the first linkage rod 810 can be rotationally driven via the rotating shaft 500, thereby driving and moving the seat support member 300. In this embodiment, as shown in FIG. 26 , the cross section of the rotating shaft 500 is approximately square, and the first linkage rod 810 is provided with a through hole (not shown), and the rotating shaft 500 extends through the through hole and is interference-fitted into the through hole.

[0041] The above-described child carrier 10 has at least the following technical advantages.

[0042] The handle 200 of the child carrier 10 described above can be rotated relative to the frame 100, thereby allowing the seat support member 300 to move from a first position to a second position relative to the frame 100. Because the seat support member 300 is configured to support the seat, a child sitting in the seat can move together with the seat support member 300, i.e., the center of gravity of the entire child carrier 10 changes. In this way, a user can adjust the center of gravity of the child carrier 10 by rotating the handle 200, so that after rotating the handle 200 to change the direction of movement of the child carrier 10, the center of gravity of the child carrier 100 moves rearward, making it easier to push the child carrier 10. In addition, the center of gravity of the child carrier 10 can be moved upward to reduce the child's inhalation of automobile exhaust, or moved downward to increase the stability of the entire child carrier 10.

[0043] Although each embodiment has been described individually, it should be understood that each embodiment is inseparable. As will be apparent to those skilled in the art after reading the disclosure of this application, the technical features included in each embodiment can be arbitrarily combined between the respective embodiments as long as they are not mutually contradictory. Of course, the technical features listed in the same embodiment can also be arbitrarily combined as long as they are not mutually conflicting.

[0044] The above description is merely a specific embodiment of the present disclosure and is not intended to limit the scope of protection of the present disclosure. Any variations or replacements that can be easily conceived by those skilled in the art within the technical scope disclosed in the present disclosure shall all fall within the scope of protection of the present disclosure.
