DETAILED DESCRIPTION

[0034] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0035] The present invention provides a folding mechanism 100 and a child carrier 200 having the folding mechanism 100. Figures 1 to 4 , the specific structure of the child carrier 200 provided by the present invention is described:

[0036] Please refer to Figure 1 and Figure 2The child carrier 200 provided by the present invention includes, but is not limited to, for example, a child sleeping box, a basket, a crib, and a baby carriage. Specifically, in a preferred embodiment of the present application, the child carrier 200 is a sleeping box, which includes a handle 201, an upper frame 202, a download board 203, a side bracket 204, and a folding mechanism 205. The handle 201 is pivotally connected to the upper frame 202, and the side bracket 204 is connected between the download board 203 and the upper frame 202. The folding mechanism 205 can be arranged on the side bracket 204 to reduce the overall height of the side bracket 204, thereby reducing the height of the entire child carrier 200. Of course, in other embodiments, the folding mechanism 205 can also be arranged on the download board 203 and the upper frame 202 to reduce the length or width of the download board 203 and the upper frame 202, thereby reducing the length or width of the entire child carrier 200, which can also play a role in reducing the volume for carrying and storage.

[0037] Specifically, the upper frame 202 and the lower plate 203 are arranged parallel to each other and spaced apart from each other, and the left and right sides or / and the front and rear sides of the two can be connected to a side bracket 204, so that a bearing space for infants to lie or sit is enclosed between the upper frame 202, the lower plate 203 and the side bracket 204 on the opposite side. Of course, seat cloths and additional seat cushions can be wrapped on the upper frame 202, the lower plate 203 and the side brackets 204, so that infants can sit safely and comfortably in the sleeping box. Among them, the folding mechanisms 205 are arranged on the side brackets 204 in a one-to-one correspondence, and the folding mechanisms 205 on the side brackets 204 on the opposite sides are arranged symmetrically, so that the side brackets 204 can be folded and unfolded more smoothly.

[0038] Please combine Figures 1 to 4 The side bracket 204 includes a first bracket 2041 and a second bracket 2042 which are connected and can move relative to each other. The first bracket 2041 and the second bracket 2042 are rotatably connected or slidably connected, so that the purpose of folding and unfolding can be achieved through relative rotation or sliding between the two. The folding mechanism 100 provided in the preferred embodiment of the present invention includes a driving member 10, an operating member 20 and a locking member 30 arranged at the connection between the first bracket 2041 and the second bracket 2042. The driving member 10 and the operating member 20 are arranged in linkage, and the driving member 10 and the locking member 30 are arranged to be snap-connected. The operating member 20 can drive the driving member 10 to snap-connect or separate with the locking member 30 to limit or release the relative movement of the first bracket 2041 and the second bracket 2042, so that the first bracket 2041 and the second bracket 2042 can move relative to each other to fold or unfold. The first bracket 2041 and the second bracket 2042 are cylindrical or plate-shaped, and can be pivotally connected, sleeved or overlapped, so that the overall size can be changed by relative rotation or sliding between them.

[0039] Specifically, in this embodiment, the first bracket 2041 includes a first connecting portion 2043 and a first pivoting portion 2044, the second bracket 2042 includes a second pivoting portion 2045 and a second connecting portion 2046, the first connecting portion 2043 is rotatably connected to the upper frame 202, the first pivoting portion 2044 and the second pivoting portion 2045 are pivotally connected via a first pivot axis 2047, and the second connecting portion 2046 is rotatably connected to the download plate 203.

[0040] More specifically, the first bracket 2041 has a receiving cavity arranged along its longitudinal direction and located between the first connecting portion 2043 and the first pivot portion 2044. The driving member 10 is inserted into the receiving cavity with a clearance fit. A portion of the operating member 20 extends from one side of the first bracket 2041 along the horizontal width direction of the first bracket 2041 into the receiving cavity and passes through the driving member 10. It can then be slidably engaged in the through hole 204a on the other side of the first bracket 2041. The top end of the second bracket 2042 has a locking member 30 that matches the driving member 10.

[0041] In order to realize the corresponding connection between the side bracket 204 and the download plate 203 and the upper frame 202, the side bracket 204 also includes a first auxiliary part 2048 and a second auxiliary part 2049. One end of the first auxiliary part 2048 is rotatably sleeved on the upper frame 202, and the other end of the first auxiliary part 2048 is fixedly connected to the first connecting part 2043. One end of the second auxiliary part 2049 is fixedly connected to the download plate 203, and the other end of the second auxiliary part 2049 is pivotally connected to the second connecting part 2046 through a second pivot shaft 2050.

[0042] Please see below Figures 5 to 7 , the specific structure of the folding mechanism 100 provided by the present invention is described:

[0043] The driving member 10 and the operating member 20 are movably or rotatably mounted at the connection between the first bracket 2041 and the second bracket 2042, and the locking member 30 is fixedly mounted at the connection between the first bracket 2041 and the second bracket 2042. Specifically, in the present embodiment, the operating member 20 is movably mounted on one of the first bracket 2041 and the second bracket 2042, the driving member 10 is movably mounted on the first bracket 2041 or the second bracket 2042 having the operating member 20, one end of the driving member 10 is fixedly connected to the operating member 20, and the other end of the driving member 10 is detachably engaged with the locking member 30 fixedly mounted on the other of the first bracket 2041 and the second bracket 2042. The operating member 20 and the driving member 10 move along the longitudinal direction of the first bracket 2041 or the second bracket 2042. The driving member 10 is plate-shaped, the operating member 20 is plug-shaped, and the locking member 30 is groove-shaped. Specifically, the locking member 30 is a limiting groove, and in order to facilitate the engagement with the driving member 10 , the notch of the limiting groove has an arc-shaped guiding surface. Correspondingly, the engaging end of the driving member 10 and the locking member 30 also has an arc-shaped guiding surface.

[0044] More specifically, the driving member 10 includes a fixing portion 11 and a limiting portion 12 arranged at both ends thereof along its longitudinal direction, the fixing portion 11 is fixedly connected to the operating member 20, and the limiting portion 12 is detachably engaged with a locking member 30 provided at the top end of the second bracket 2042 or at the bottom end of the first bracket 2041. The fixing portion 11 is at least one socket hole located at the relatively upper side end of the driving member 10, and the limiting portion 12 is at least one plug-in block located at the relatively lower side end of the driving member 10. The block-shaped limiting portion 12 is matched with the groove-shaped locking member 30. When the limiting portion 12 is inserted into the locking member 30, the first bracket 2041 and the second bracket 2042 are in an unfolded state connected in a straight line or an oblique line, thereby playing a good supporting role; when the limiting portion 12 is disengaged from the locking member 30, the first bracket 2041 and the second bracket 2042 can rotate around the first pivot axis 2047, and the two begin to have a certain angle and fold until they are folded to the minimum volume.

[0045] More specifically, the operating member 20 includes a plug-in portion 21 and a push-pull portion 22 arranged on opposite sides thereof along its transverse width direction. The plug-in portion 21 can be slidably engaged in the through hole 204a of the first bracket 2041 after passing through the fixed portion 11 of the driving member 10. The push-pull portion 22 can be slidably engaged with the right side wall of the first bracket 2041 and is arranged to protrude from the right side wall. The push-pull portion 22 is a push block that can slide on the right side wall of the first bracket 2041. The plug-in portion 21 is at least one through-connection column formed by the side where the push block and the first bracket 2041 are in contact with each other and protrudes in the direction away from the push block. The through-connection column and the through hole 204a are arranged to match. The through hole 204a is a bar-shaped through hole that penetrates the left and right side walls of the first bracket 2041. Its upper and lower inner walls can stop the movement of the columnar plug-in portion 21.

[0046] Specifically, the folding mechanism 100 further includes an elastic member 40, which is connected between the first bracket 2041 and the operating member 20 or between the first bracket 2041 and the driving member 10, and plays a role in constantly driving the driving member 10 to move in the direction of engaging with the second bracket 2042. The elastic member 40 is a compression spring.

[0047] When the child carrier 200 needs to be folded, the operating member 20 is pushed upward, the elastic member 40 is compressed, and the driving member 10 is moved upward under the drive of the operating member 20 and separated from the locking member 30 to unlock, so that the first bracket 2041 and the second bracket 2042 can be relatively rotated and folded; when the child carrier 200 needs to be unfolded, the operating member 20 can be pushed upward first to drive the driving member 10 to give way, and when the first bracket 2041 and the second bracket 2042 are unfolded to the fully opened position, the operating member 20 is released, and under the action of the restoring force of the elastic member 40, the driving member 10 can be reset downward to be engaged with the locking member 30; and in the preferred embodiment of the present application, since the engaging ends of the driving member 10 and the locking member 30 have corresponding arc-shaped guiding surfaces, there is no need to manually push the operating member 20 upward when unfolding, but the arc-shaped guiding surfaces corresponding to the driving member 10 and the locking member 30 cooperate with the elastic member 40 to automatically achieve giving way and being engaged in place.

[0048] Compared with the prior art, the folding mechanism 100 of the present invention is assembled on the side bracket 204 of the child carrier 200. The folding mechanism 100 includes a driving member 10, an operating member 20 and a locking member 30 arranged at the connection between the first bracket 2041 and the second bracket 2042 of the side bracket 204. Since the driving member 10 and the operating member 20 are arranged in a linkage, and the locking member 30 and the driving member 10 are arranged to be snap-connected, the first bracket 2041 and the second bracket 2042 are connected to each other and can move relative to each other, and the side bracket 204 is connected to the child carrier 204. 00 between the download plate 203 and the upper frame 202, in actual use, by pushing and pulling the operating member 20, the driving member 10 and the locking member 30 can be driven to engage or separate, thereby limiting or releasing the relative movement of the first bracket 2041 and the second bracket 2042, so that the two can move relative to each other to unfold or fold, thereby reducing the volume of the entire child carrier 200 by folding the side bracket 204 that plays a supporting role, making it easy to carry and store, and by unfolding the side bracket 204 to strengthen the support and improve the safety of use. The folding mechanism 100 of the present invention and the child carrier 200 having the folding mechanism 100 are simple in structure and easy to operate, which effectively improves the user's experience.

[0049] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
