[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 by reference.

[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, can have the function of changing the forward direction by 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 center of gravity of the baby 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 the stroller push harder and more inconvenient. Moreover, the height of the center of gravity of the stroller cannot be adjusted as needed, which results in a poor user experience. Summary of the Invention

[0004] According to some embodiments, a child carrier is provided that includes a frame, a seat support member configured to support a seat, and a handle pivotally connected to the frame and rotatable relative to the frame to actuate the seat support member to move from a first position to a second position relative to the frame.

[0005] The handle of the aforementioned child carrier can be rotated relative to the frame so that the seat support member can move from a first position to a second position relative to the frame. Since the seat support member is configured to support the seat, a child sitting on the seat can move together with the seat support member, i.e., the center of gravity of the entire child carrier is changed. In this way, a user can adjust the center of gravity of the child carrier by rotating the handle, so that the center of gravity of the child carrier moves backward after the moving direction of the child carrier is changed by rotating the handle.

[0018] In one embodiment, the support rod is disposed along a first direction and the second location is located above or below the first location.

[0019] In one embodiment, the second linkage assembly includes a first linkage rod and a second linkage rod, one end of the first linkage rod is fixed to the handle, the other end of the first linkage rod is pivotally connected to one end of a seat support member, the other end of the seat support member is pivotally connected to one end of a second linkage rod, and the other end of the second linkage rod is pivotally connected to a support rod, and the first linkage rod, the seat support member, the second linkage rod, and the support rod are connected in series to form a deformable quadrilateral structure.

[0027] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present 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 are not to be interpreted in an idealized or overly formal sense unless expressly defined in this specification.

[0028] As shown in Figures 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 is 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 with respect to the frame 100 to change the moving direction of the frame 100 from a first direction D1 to a second direction D2, and at the same time, drives the seat support member 300 to move from a first position (see Fig. 2) to a second position (see Fig. 4) with respect to the frame 100. The second position is located in the first direction D1 of the first position. The first direction D1 may be, for example, a horizontal left direction as shown in Fig. 1, and the second direction D2 may be, for example, a horizontal right direction as shown in Fig. 1. With respect to the second direction D2 (i.e., the moving 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 moving 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. Since the seat support member 300 is configured to support a seat, the child sitting on the seat moves with the movement of the seat support member 300, that is, the center of gravity of the entire child carrier 10 is changed. In this way, the user can adjust the center of gravity of the child carrier 10 by rotating the handle 200, so that 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 the child carrier 10 moves upward as the handle 200 rotates. In this way, the height of the child sitting on the child carrier 10 can be increased, and the inhalation of harmful gases such as automobile exhaust by the child can be reduced, which is beneficial to the health of the child. When the second position is located below the first position, the center of gravity of the child carrier 10 moves downward as the handle 200 rotates, thereby increasing the overall stability of the child carrier 10 and improving the safety performance of the child carrier 10.

[0031] Specifically, as shown in Fig. 5 and Fig. 6, the frame 100 includes a support rod 110, a first wheel support 120, and a second wheel support 130. The ends of the first wheel support 120 and the second wheel support 130 are connected to the first wheel 140 and the 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 can also be rotatably connected to the first wheel support 120 or the second wheel support 130.

[0032] In one embodiment, as shown in Figs. 1-16, 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) located 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, so that the seat support member 300 can move more smoothly along the support rod 110. In this embodiment, four pulleys are provided, two pulleys abut the upper side of the support rod 110, and the other two pulleys abut the lower side of the support rod 110. Of course, in other embodiments, the number and arrangement of the pulleys can also be changed as necessary.

[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 located above the seat support member 300, and the center of the arc shape of the driving member 420 is located below the driving member 420. Of course, in other embodiments, both the rotating member 410 and the driving member 420 may be located 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 connected to each other. The first rod 111 is arranged 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 the rotating member 410 is fixed to the handle 200, the other end of the rotating member 410 is rotatably connected to one end of the driving member 420, and the other end of the driving member 420 is rotatably connected to the seat support member 300. In this way, as shown in FIG. 13 and FIG. 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 and move under the pulling force of the handle 200, thereby driving the seat support member 300 to move along the support rod 110. Since the seat support member 300 is always moved corresponding to the rotation direction of the handle 200 by driving the handle 200, and the handle 200 is always on the same side as the rear wheel with respect to the moving direction, the seat support member 300 can be automatically driven away from the moving direction along the support rod 110 with the rotation of the handle 200, and the center of gravity of the entire child carrier 10 moves backward, thereby making it easier to push the child carrier 100 after the moving direction of the child carrier 10 is changed by rotating the handle 200.

[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 manner, 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] Further, as shown in Fig. 5, Fig. 9 and Fig. 10, the handle 200 includes a handle holder 210 located at the end of the handle 200. The rotating shaft 500 is fixed to the handle holder 210, and the connection between the rotating shaft 500 and the handle holder 210 can be strengthened by a fixing plate 600. Specifically, the fixing plate 600 may be in the shape of a partial gear, the rotating shaft 500 extends through the central hole of the fixing plate 600 and is fixed to the central hole, and the 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 the 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 in this specification.

[0037] 15 and 16, the 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 side 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 position of the child carrier 10 can be changed.

[0039] Specifically, as shown in FIG. 22 to FIG. 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 the seat support member 300. The other end of the seat support member 300 is rotatably connected to one end of the second linkage rod 820, and the other end of the second linkage rod 820 is rotatably connected to the 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 located 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, when the handle 200 is rotated in the third direction D3 as shown in Fig. 17 and Fig. 18, the first linkage rod 810, the seat support member 300, and the second linkage rod 820 can rotate and move under the pulling force of the handle 200. The seat support member 300 is always moved corresponding to the rotation direction of the handle 200 by driving the handle 200, and since the handle 200 is always on the same side as the rear wheel with respect to the moving direction, the seat support member 300 can be automatically driven away from the moving direction along the support rod 110 with the rotation of the handle 200, and the center of gravity of the entire child carrier 10 moves backward, which makes it easier to push the child carrier 100 after the handle 200 is rotated to change the moving direction of the child carrier 10. Meanwhile, as shown in Figures 18 and 19, the first linkage rod 810, the seat support member 300, the second linkage rod 820 and the support rod 110 form a deformable quadrilateral structure, so that the distance between the seat support member 300 and the support rod 110 can also be changed during rotation of the handle 200.That is, the height of seat support member 300 is changed, thereby changing the height of the center of gravity of child carrier 10. In this manner, a user can adjust the height of the center of gravity of child carrier 10 as needed by rotating 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 the first linkage rod 810 is fixed to the rotating shaft 500. In this manner, 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 substantially 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 press-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, so that the seat support member 300 can move from a first position to a second position relative to the frame 100. Since the seat support member 300 is configured to support the seat, the child sitting on the seat can move together with the seat support member 300, that is, 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, so that after rotating the handle 200 to change the moving direction of the child carrier 10, the center of gravity of the child carrier 100 moves backward, 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 the center of gravity of the child carrier 10 can be moved downward to increase the stability of the entire child carrier 10.

[0043] Although each embodiment has been described one by one, it should be understood that each embodiment is not separate. As will be apparent to those skilled in the art, upon reading the disclosure of this application, each technical feature included in each embodiment can be arbitrarily combined between each embodiment as long as they are not inconsistent with each other. Of course, each technical feature listed in the same embodiment can also be arbitrarily combined as long as they do not conflict with each other.

[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 are easily conceived by those skilled in the art within the technical scope disclosed in the present disclosure shall fall within the scope of protection of the present disclosure.
