When a component is referred to as being “disposed on” another component, it can be directly disposed on the other component or there can be a middle component.

[0053] 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 terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms “and / or” includes any and all combinations of one or more of the associated listed items.

[0054] In the present application, the terms “first”, “second”, etc. are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, the features defined with “first”, “second” can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of “a plurality of” is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0055] Reference Figures 1 to 5The present application provides a carrying device 1000 with an open top containing space 190, which can accommodate children, for example, and the carrying device 1000 is a child's sleeping basket, or can accommodate pets, and the carrying device 1000 is a pet basket.

[0056] The carrying device 1000 further comprises a support framework 100 and two adapters 180 arranged on both sides of the support framework 100. In the illustration, the support framework 100 has a length direction in which X is located and a width direction in which Y is located, and the two adapters 180 are arranged on both sides of the width direction of the support framework 100. The adapters 180 are used to connect the support device 4000, and the adapters 180 can be fixedly connected with the support device 4000 or detachably connected with the support device 4000. Among them, the support framework 100 rotates relative to the adapters 180 and has a storage state (for example Figure 3 illustrated) in which the support framework 100 is close to the support device 4000, and an unfolded use state (for example Figure 2 illustrated) in which the support framework 100 is away from the support device 4000.

[0057] The support framework 100 comprises a top frame 110, a bottom frame 120, side frames 140 and a linkage 148. The top frame 110 defines an open port at the top of the containing space 190, which is used for children or articles to enter or exit the containing space 190. The structure of the top frame 110 includes but is not limited to a closed annular frame. The bottom frame 120 provides bottom support for the containing space 190 and is arranged opposite to the top frame 110. The adapters 180 are rotatably connected with the bottom frame 120 or the top frame 110. The side frames 140 are arranged in pairs along the width direction. The side frames 140 are foldably arranged between the top frame 110 and the bottom frame 120. When the side frames 140 are folded, the top frame 110 and the bottom frame 120 are close to each other. When the side frames 140 are unfolded, the top frame 110 and the bottom frame 120 are separated to form the containing space 190. In a preferred embodiment, the top frame 110 and the bottom frame 120 are aligned when they are close to each other and separated.

[0058] The linkage 148 is arranged between the side frames 140 and the corresponding adapters 180. When the support framework 100 rotates relative to the adapters 180, the linkage 148 synchronously switches the side frames 140 between the folded state and the unfolded state. The rotation of the support framework 100 relative to the adapters 180 and the folding and unfolding of the side frames 140 occur simultaneously, and there is no strict active and passive relationship between them. For example, the folding and unfolding of the side frames 140 can drive the rotation of the support framework 100 relative to the adapters 180, and for example, the rotation of the support framework 100 relative to the adapters 180 can drive the folding and unfolding of the side frames 140.

[0059] The following will be described in connection with a method for using one of the bearing devices:

[0060] Referring to Figures 2 to 4 shown, Figure 2 In the folding process, the support framework 100 is rotated relative to the adapter 180 along the second direction shown by the arrow, and at the same time, the support framework 100 is folded, and finally the bottom frame 120 is tilted relative to the horizontal state. In the folding process, the external force applied to the support framework 100 can be artificially applied, or provided when the top frame 110 falls under the action of gravity, or artificially and when the top frame 110 falls under the action of gravity.

[0061] The unfolding process includes driving the support framework 100 to rotate relative to the adapter 180 along the first direction (opposite to the second direction), and at the same time, the support framework 100 is unfolded until the bottom frame 120 is in a horizontal state, and the support framework 100 is in an unfolded state. Among them, the external force applied to the support framework 100 is artificially provided to overcome the gravity of the top frame 110 to move away from the bottom frame 120.

[0062] In another embodiment, the adapter 180 is rotatably connected to the top frame 110. The folding process and the unfolding process refer to the foregoing embodiment, except that in the folding process, it is necessary to artificially apply the support framework 100 to rotate relative to the adapter 180, so that the bottom frame 120 moves upward to approach the top frame 110 against gravity; on the contrary, in the unfolding process, the external force required for the rotation of the support framework 100 can be completely provided by the bottom frame 120 falling under the action of gravity, or artificially provided, or both.

[0063] The bearing device of the present application is connected to the support device, and the folding and unfolding of the support framework are simultaneously and interrelatedly rotated relative to the adapter of the support framework, for example, in the storage process, the support framework is rotated in the second direction while being folded; in the unfolding process, the support framework is rotated in the first direction while being unfolded, which is more convenient than the prior art.

[0064] For other structures of the bearing device 1000, in an embodiment, the support framework 100 is in an unfolded state, and the bottom frame 120 is in a horizontal state. The support framework 100 is in a folded state, and the bottom frame 120 is tilted relative to the horizontal state, specifically, the bottom frame 120 is tilted and approached to the support device 4000, which is convenient for storage.

[0065] Among them, referring to Figure 6The first hinge point 181 is between the adapter 180 and the bottom frame 120 or the top frame 110, the second hinge point 182 is between the adapter 180 and the linkage 148, the third hinge point 183 is between the linkage 148 and the side frame 140, and the fourth hinge point 184 is between the side frame 140 and the bottom frame 120 or the top frame 110. The sequentially connected first hinge point 181, second hinge point 182, third hinge point 183, and fourth hinge point 184 form a foldable four-bar linkage.

[0066] In an embodiment, the carrying device 1000 comprises a locking device for locking the support framework 100 so that the support framework 100 is kept in the unfolded state. When the carrying device 1000 is kept in the unfolded state, the support framework 100 is relatively fixed relative to the adapter 180, i.e., the carrying device 1000 is kept in the unfolded state of use, and accordingly, the unlocking operation and the unlocking member are only for the locking device, thereby saving costs. The locking device can be of the prior art or the following embodiments.

[0067] Referring to Figure 1 , Figure 6 and Figure 7 In an embodiment, the support framework 100 further comprises a connecting seat 130 and a driving member for connecting the two side frames 140. The connecting seat 130 is used to connect the two side frames 140 and is slidingly installed on the bottom frame 120 and has a first position and a second position on the sliding path. When the connecting seat 130 slides between the two positions, the corresponding side frames switch between the folded state and the unfolded state. The driving member is used to drive the connecting seat 130 to slide from the first position to the second position to unfold the side frames 140.

[0068] The structure of the side frame 140 includes but is not limited to the structure provided in the present application. The side frame 140 comprises a plurality of first side rods 141, each of which is inclined in the same direction, for example, the top frame 110 and the bottom frame 120 have a certain angle. For another example, in the illustration, the top frame 110 and the bottom frame 120 are parallel to each other, and the first side rods 141 are also parallel to each other. The connecting seat 130 is connected to all the first side rods 141 to realize synchronous movement of the first side rods 141, thereby ensuring that the two side frames 140 can be folded or unfolded synchronously. Further, the side frame 140 further comprises a second side rod 142, one end of which is hinged to the first side rod 141, and the other end is hinged to the bottom frame 120. The second side rod 142 and the first side rod 141 are inclined in opposite directions, thereby improving the structural stability of the support framework 100 in the unfolded state. One end of the linkage 148 is hinged to the second side rod 142, and the other end is hinged to the adapter 180. The linkage 148 is a rod member.

[0069] In actual operation, when the support framework 100 is in the folded state, the operating driving member drives the connecting seat 130 to move along the third direction, the upper part of the first side stop rod 141 moves upward to drive the top frame 110 to move away from the bottom frame 120, until the support framework 100 is in the unfolded state; when folding, the top frame 110 is pressed downward, so that the connecting seat 130 slides along the fourth direction, until the support framework 100 is in the folded state. Compared with the prior art, the unfolding operation is more convenient.

[0070] For emphasis Figure 8 , the bearing device 1000 further comprises a flexible waistband 200 connected between the top frame 110 and the bottom frame 120 and wrapping the side frame 140, in the unfolded state, the flexible waistband 200 pulls the top frame 110 and the bottom frame 120 to make the support framework 100 unfold to the maximum height, indirectly limiting the connecting seat 130 to continue moving in the pulling direction.

[0071] Among them, the connecting seat 130 can be a crossbar, or a frame composed of a plurality of rod members, or a component slidingly sleeved on the bottom frame, etc. For example Figure 7 As shown in the figure, in an embodiment, the connecting seat 130 is a frame structure, including two crossbars 131 corresponding to a pair of first side stop rods 141, and at least one longitudinal rod 132 connected between the two crossbars 131, the two ends of the crossbar 131 are slidingly matched with the bottom frame 120, and the two side frames 140 are hinged with the connecting seat 130, for example, a pair of first side stop rods 141 symmetrically arranged in the two side frames 140 are hinged with one of the crossbars 131, and the other pair of first side stop rods 141 are hinged with the other crossbar 131. For another example, the connecting seat 130 includes a sliding member slidingly matched with the bottom frame 120 and a transverse member connecting the two sliding members, and the first side stop rods 141 on the same side are hinged with the sliding member.

[0072] Further, the bearing device 1000 further comprises a locking device 160 for locking the support framework 100 to keep it in the unfolded state, the locking can be provided between the connecting seat 130 and the bottom frame 120, that is, the connecting seat 130 is locked.

[0073] In some embodiments, the locking device 160 achieves locking by limiting the movement of the driving member, it is emphasized that the object of the locking device 160 is the driving member. Specifically, the driving member is a flexible member 150, which pulls the connecting seat 130 to unfold the support framework 100, and the flexible member 150 is in the shape of a belt or a wire or a combination of the two, such as a nylon belt or a steel wire, or a combination of the two, etc. When the bearing device of the present application is unfolded, the locking device 160 acts on the corresponding position of the flexible member 150 to keep the support framework 100 always in the unfolded state, avoiding folding due to improper locking and causing safety accidents.

[0074] The flexible member 150 has a fixed end 151 and an operating end 152, and the operating end 152 is exposed outside the support framework 100. When the pulling and unfolding operation is performed, the length of the operating end 152 exposed outside the support framework 100 increases. The connection relationship between the flexible member 150 and the connecting seat 130 adopts at least one of the following:

[0075] a) The fixed end 151 is fixedly connected to the bottom frame 120, and the operating end 152 bypasses the connecting seat 130 and is located on the same side of the fixed end 151 (for example Figure 6 ), and preferably, the operating end 152 bypasses one of the horizontal rods 131, and the outer contour of the horizontal rod 131 in contact with the flexible member 150 is circular, for example, a round rod, which facilitates the movement of the flexible member 150;

[0076] b) The fixed end 151 is fixedly connected to the connecting seat 130 (for example Figure 9 ).

[0077] The locking device 160 allows the flexible member 150 to move in the pulling direction (corresponding to the movement of the connecting seat in the third direction) and prevents the flexible member 150 from moving in the opposite direction (i.e., the return direction described below) (corresponding to the movement of the connecting seat in the fourth direction). The locking device 160 has:

[0078] a locking state, which allows the flexible member 150 to move in the pulling direction in one direction, i.e., limits the movement of the flexible member 150 in the return direction;

[0079] an unlocked state, which allows the flexible member 150 to move in both directions.

[0080] As shown in Figures 10 to 12 , the locking device 160 includes a lock seat 161, a lock member 162, and a spring acting on the lock member 162. The lock member 162 and the lock seat 161 form a channel 163 for the flexible member 150 to pass through. In the locked state, the lock member 162 and the lock seat 161 clamp the flexible member 150, and in this state, the lock member 162 can only rotate in one direction. Specifically, the lock member 162 is rotatably installed in the lock seat 161, and a spring (for example, a torsion spring) is arranged between the lock member 162 and the lock seat 161. The lock member 162 has lock teeth 164, and the lock teeth 164 and the lock seat 161 provide clamping force.

[0081] The lock member 162 rotates relative to the lock seat 161 and has an unlocking direction (indicated by the arrow in Figure 12 ) and a locking direction. When the operating end 152 of the flexible member 150 moves in the pulling direction, a force is applied to the lock member 162 to rotate in the unlocking direction, thereby reducing or even eliminating the clamping force of the lock member 162 and the lock seat 161 on the flexible member 150; as Figure 11As shown, when the operating end 152 of the flexible member 150 moves in the retreat direction, the force applied to the locking member rotates the locking member in the locking direction, gradually increasing the clamping force of the locking member 162 and the locking seat 161 on the flexible member 150, similar to self-locking. This structure realizes the one-way movement of the flexible member 150 mentioned above, and can make the locking device 160 act on any position of the flexible member 150, ensuring that the support framework is in an unfolded state, thereby ignoring the error caused by processing and assembly. Before folding the carrying device, manually press the locking member 162 to unlock it, and then press the top frame 110 to fold.

[0082] In combination with the accompanying drawings Figures 2 to 4 From Figures 4 to 2 For the unfolding use process of the support framework 100, specifically, the adapter 180 is rotatably connected to the two sides of the bottom frame 120. During unfolding, the flexible member 150 is pulled, thereby driving the support framework 100 to rotate relative to the adapter 180 in the first direction until the bottom frame 120 is in a horizontal state. Among them, the direction of pulling the flexible member 150 is the same as the horizontal direction of the first direction.

[0083] Among them, the locking device 160 is arranged at the edge of the bottom frame 120, for example, the side in the X direction in the figure. In an embodiment, the locking member 162 is limited from further rotating in the locking direction in the locked state. The limiting way can be that the locking seat 161 is provided with a limiting portion abutting against the locking member 162, for example, a boss on the locking seat 161. In an embodiment, a connecting structure for fixing the flexible member 150 is arranged between the flexible member 150 and the flexible apron 200, for example, a magic buckle arranged between the flexible member 150 and the flexible apron 200, to avoid the part of the flexible member 150 exposed outside the flexible apron 200 from shaking randomly.

[0084] Referring to Figures 13 to 15 The present application also provides a child carrier 5000, which comprises a support device 4000 and a carrying device 1000 connected to the support device 4000 through the adapter 180. The support device 4000 comprises two oppositely arranged side frames 400 and an adapter seat 410 arranged on the side frame 400, and the adapter 180 and the adapter seat 410 are detachably connected.

[0085] For the specific structure of the support device 4000:

[0086] Referring to Figures 2 to 4In an embodiment, the side frame 400 comprises a first leg assembly 420 and a second leg assembly 430, the top of the first leg assembly 420 and the second leg assembly 430 are hinged to each other by a rotating joint, and the adapter 180 is connected to the rotating joint or one of the leg assemblies. The first leg assembly 420 and the second leg assembly 430 have a folded state of rotating towards each other and a use state of rotating away from each other.

[0087] Referring to Figures 13 to 15 In another embodiment, the side frame 400 comprises a first leg assembly 420, a second leg assembly 430 and a handle assembly 440, two of the three are hinged to each other, and the third is hinged to at least one of the other two. When folding, the first leg assembly 420 and the handle assembly 440 rotate towards the second leg assembly 430, and the support frame 100 rotates relative to the adapter 180 to close the first leg assembly 420 or the second leg assembly 430.
