[0197] According to a first embodiment of the present application, a support connection assembly 10 , a support connection structure 1 equipped with the support connection assembly 10 , and a child carrier equipped with the support connection structure 1 are provided.

[0198] Figures 1 to 4 The structural schematic diagram of the support connection assembly 10 of the support connection structure 1 provided according to the first embodiment of the present application is shown. The support connection assembly 10 includes a mobile connection assembly 11, which has a locked state and a released state. Among them, the mobile connection assembly 11 includes a pivot seat 111, at least one set of pivot arms 112 and at least one mobile locking member 113, and the mobile locking member 113 serves as a locking member of the support connection assembly 10. The pivot arm 112 and the mobile locking member 113 are mounted on the pivot seat 111. The support connection structure 1 can be applied to a baby carrier, for example, but is not limited to a baby carrier. The baby carrier can be, for example, a crib (including a baby hammock, a baby playbed and other types of cribs), a baby stroller, etc., so as to allow the rod of the baby carrier equipped with the support connection structure 1 to be unfolded and folded, so as to switch between the use state and the folded state to meet the different use needs of users.

[0199] like Figure 1 to Figure 2As shown, each set of pivot arms 112 includes a first pivot arm 112a and a second pivot arm 112b respectively pivoted to the same side of the pivot seat 111, and the first pivot arm 112a and the second pivot arm 112b are arranged at intervals. The pivot axis of the first pivot arm 112a relative to the pivot seat 111 is X1-X1. The pivot axis of the second pivot arm 112b relative to the pivot seat 111 is X2-X2, and the pivot axes X1-X1 and X2-X2 are roughly parallel. The moving direction MD1 of the movable locking member 113 relative to the pivot seat 111 is roughly perpendicular to the pivot axis X1-X1. The movable locking member 113 is movably arranged on the pivot seat 111 and can be switched between a moving release position and a moving locking position. When the mobile locking member 113 is in the mobile locking position, the mobile connecting assembly 11 is in a locked state, the mobile locking member 113 abuts against the first pivot arm 112a and the second pivot arm 112b respectively to limit the first pivot arm 112a and the second pivot arm 112b from pivoting, and the locking member 113 limits the first pivot arm 112a and the second pivot arm 112b to the unfolded position. When the mobile locking member 113 is in the mobile unlocking position, the mobile connecting assembly 11 is in an unlocking state, the first pivot arm 112a and the second pivot arm 112b can rotate relative to the pivot seat 111, and the mobile locking member 113 allows the first pivot arm 112a and the second pivot arm 112b to pivot between the unfolded position and the folded position.

[0200] like Figure 1 to Figure 2 As shown, the mobile connection assembly 11 can be configured with two groups of pivot arms 112, and the two groups of pivot arms 112 are respectively arranged on opposite sides of the pivot seat 111. In some embodiments, the mobile connection assembly 11 can be configured with two mobile locking members 113, namely a first mobile locking member 113a and a second mobile locking member 113b. The two mobile locking members 113 act on different groups of pivot arms 112 respectively. That is, the first mobile locking member 113a is used to limit or allow the pivoting of one group of the first pivot arm 112a and the second pivot arm 112b on the same side as the first mobile locking member 113a, and the second mobile locking member 113b is used to limit or allow the pivoting of another group of the first pivot arm 112a and the second pivot arm 112b on the same side as the second mobile locking member 113b. It can be understood that in other embodiments, the mobile connection assembly 11 can be configured with one group of pivot arms 112 and one mobile locking member 113. In other embodiments, the moving assembly may be configured with two groups of pivot arms 112 and a moving locking member 113, and the moving locking member 113 acts on the two groups of pivot arms 112 respectively. This application does not limit this.

[0201] like Figure 1 to Figure 2As shown, the pivot seat 111 includes a receiving groove 1113 suitable for receiving the movable locking member 113, and the receiving groove 1113 is surrounded by a top wall 1114 and a pair of side walls 1115 connected to opposite sides of the top wall 1114. The end of the pivot arm 112 is received in the receiving groove 1113, and is pivotally connected to the pair of side walls 1115 of the pivot seat 111 through a pin (not shown in the drawings), such as a rivet, a screw, a bolt, etc. Among them, the second pivot arm 112b is closer to the top wall 1114 of the pivot seat 111 than the first pivot arm 112a. When the second pivot arm 112b is in the unfolded state, the end of the second pivot arm 112b received in the receiving groove 1113 can abut against the top wall 1114 of the pivot seat 111 to avoid excessive pivoting.

[0202] Further, the pivot seat 111 is provided with a slide groove 1111, specifically, the side wall 1115 of the pivot seat 111 is provided with a slide groove 1111. The slide groove 1111 is in a long strip shape and extends in a direction parallel to the moving direction MD1 of the moving locking member 113. Figure 3 The movable locking member 113 is provided with a connecting protrusion 1133, which is plugged into and matched with the slide groove 1111 and can move along the slide groove 1111. Through the plugging and matching of the connecting protrusion 1133 and the slide groove 1111, the movable locking member 113 is movably connected to the pivot seat 111. It can be understood that in some other embodiments, the movable locking member 113 can also be provided with the slide groove 1111, and the pivot seat 111 can be provided with the connecting protrusion 1133, and this application does not limit this.

[0203] like Figures 1 to 3 As shown, the pivot seat 111 is provided with a plurality of slide grooves 1111, for example, 4 slide grooves are provided. The mobile locking member 113 is correspondingly provided with a plurality of connecting protrusions 1133, for example, each mobile locking member 113 is provided with two connecting protrusions, so that the mobile locking member 113 moves more smoothly along the MD1 direction. In order to make the mobile locking member 113 firmly connected and move smoothly, each mobile locking member 113 is actually provided with 4 connecting protrusions 1133, and the pivot seat 111 is provided with 8 slide grooves to cooperate with the two mobile locking members 113.

[0204] Figure 3The structural schematic diagram of the movable locking member 113 of the bracket connection structure 1 provided according to the first embodiment of the present application is shown. The movable locking member 113 is generally a trapezoidal block structure. The movable locking member 113 includes a first surface 1131 and a second surface 1132 arranged opposite to each other, and a first side surface 11304 and a second side surface 11305 arranged adjacent to the first surface 1131 and the second surface 1132. When the movable locking member 113 is located at the movable locking position, the first pivot arm 112a is stopped by the first surface 1131, and the second pivot arm 112b is stopped by the second surface 1132, so that the first pivot arm 112a and the second pivot arm 112b are restricted from rotating relative to the pivot seat 111. When the movable locking member 113 is located at the movable unlocking position, the first pivot arm 112a is staggered with the first surface 1131, and the second pivot arm 112b is staggered with the second surface 1132, so as to allow the first pivot arm 112a and the second pivot arm 112b to rotate relative to the pivot seat 111. In this embodiment, when the movable locking member 113 is located at the movable locking position, the first pivot arm 112a is in contact with the first surface 1131, and the second pivot arm 112b is in contact with the second surface 1132. When the movable locking member 113 is located at the movable unlocking position, the first pivot arm 112a is separated from the first surface 1131, and the second pivot arm 112b is separated from the second surface 1132. By the first pivot arm 112a being in contact with the first surface 1131, and the second pivot arm 112b being in contact with the second surface 1132, the bracket connection structure 1 is made more stable. In some embodiments, the movable locking member 113 is further provided with a guide surface 1135 adapted to guide at least one of the first pivot arm 112a and the second pivot arm 112b to pivot. In this embodiment, the guide surface 1135 is an arcuate surface provided at the connection between the second side surface 11305 and the second surface 1132. The provision of the guide surface 1135 can guide the second pivot arm 112b to pivot along the guide surface 1135, so as to prevent the movable locking member 113 from blocking the second pivot arm 112b from pivoting.

[0205] like Figure 1 to Figure 2As shown, the mobile connection assembly 11 also includes a connection member 115. The connection member 115 is driven and connected to the two mobile locking members 113 respectively, so that the two mobile locking members 113 can be switched between the mobile locking position and the mobile unlocking position synchronously. The connection member 115 is movably arranged on the pivot seat 111. The connection member 115 is at least partially accommodated in the accommodating groove of the pivot seat 111, and can move in a direction perpendicular to the pivot axis X1-X1. The moving direction MD2 of the connection member 115 is at an angle to the moving direction MD1 of the mobile locking member 113. The connection member 115 is provided with a clearance groove 1151, and when the mobile locking member 113 is located at the mobile unlocking position, the mobile locking member 113 is at least partially accommodated in the clearance groove 1151. The clearance groove 1151 has a bottom wall 1156 and a pair of side walls 1157 connected to opposite sides of the bottom wall 1156. The bottom wall 1156 faces the top wall 1114 of the pivot seat 111. The connecting member 115 is further provided with a spacer 1152, which divides the clearance groove 1151 into a first clearance groove 1151a and a second clearance groove 1151b, and the two movable locking members 113 are respectively accommodated in the first clearance groove 1151a and the second clearance groove 1151b. That is, the first movable locking member 113a is adapted to be at least partially accommodated in the first clearance groove 1151a, and the second movable locking member 113b is adapted to be at least partially accommodated in the second clearance groove 1151b. In this embodiment, when the movable locking member 113 is in the movable unlocking position, the first side surface 11304 of the movable locking member 113 can abut against the spacer 1152.

[0206] The connecting member 115 is further provided with an operating portion 1153 which can be operated, wherein the bottom wall 1156 of the clearance groove 1151 forms the operating portion 1153. When the movable locking assembly 11 is in the locked state, the operating portion 1153 at least partially extends out of the receiving groove 1113 of the pivot seat 111 to allow the operating portion 1153 to be operated, thereby driving the two movable locking members 113 to move. Fig.10 ), the operating portion 1153 is also provided with a reinforcing rib 1154 to enhance the strength of the operating portion 1153.

[0207] Furthermore, if Figures 1 to 3As shown, the pivot seat 111 is provided with a guide hole 1116, for example, the two side walls 1115 of the pivot seat 111 are provided with the guide holes 1116. The guide holes 1116 are, for example, bar-shaped holes, and the extending direction of the guide holes 1116 is substantially parallel to the moving direction MD2 of the connecting member 115. Each movable locking member 113 is provided with a driving groove 116, and the driving groove 116 is in a bar shape. The extending direction of the driving groove 116 is at an angle to the moving directions MD1 and MD2 of the movable locking member 113 and the connecting member 115. The connecting member 115 is connected to a driving member, and the driving member is slidably matched with the driving groove 116 to drive the movable locking member 113 to switch between the movable locking position and the movable unlocking position. Specifically, the connecting member 115 is provided with a connecting through hole 1155, and the connecting through hole 1155 passes through a pair of side walls of the yielding groove 1151. The connecting member 115 is driven and connected to the two movable locking members 113 respectively through the driving pin 118 that penetrates the guide hole 1116, the connecting through hole 1155 and the driving groove 116, and is movably connected to the pivot seat 111. The driving pin 118 can be, for example, a rivet, a screw, a bolt, etc. In this embodiment, the driving pin 118 is formed as a driving member. Of course, in other embodiments, the driving member can be a structure integrally formed with the connecting member 115.

[0208] It can be understood that in other embodiments not shown, the driving groove 116 can also be provided on the connecting member 115. The driving member is connected to the movable locking member 113, wherein the driving member can be a structure formed separately from the movable locking member 113 or formed in one piece. For example, the movable locking member 113 is provided with a connecting through hole 1155, and the pivot seat 111 is provided with a guide hole 1116. The guide hole 1116 is a bar-shaped hole extending in a direction roughly parallel to the moving direction MD1 of the movable locking member 113, and the guide hole 1116 can be connected to the slide groove 1111, or be the slide groove 1111. The connecting member 115 is driven and connected to the two movable locking members 113 respectively through a driving pin 118 penetrating the guide hole 1116, the driving groove 116 and the connecting through hole 1155, and the driving pin 118 is formed as a driving member.

[0209] In some embodiments, Figure 1 to Figure 2 As shown, the mobile connection assembly 11 further includes a mobile reset member 114 disposed between the two mobile locking members 113, and the mobile reset member 114 is suitable for biasing the two mobile locking members 113 to move the two mobile locking members 113 to the mobile locking position. The mobile reset member 114 is, for example, a compression spring. Figure 3, the two movable locking members 113 are each provided with a receiving groove 1136 suitable for at least partially accommodating the movable restoring member 114, so as to allow both ends of the movable restoring member 114 to be respectively accommodated in the corresponding receiving grooves 1136, thereby preventing the movable restoring member 114 from being deflected during the process of biasing the movable locking member 113. In some other embodiments, one of the two movable locking members 113 may be provided with the receiving groove 1136, and one end of the movable restoring member 114 may be accommodated in the receiving groove 1136.

[0210] According to the bracket connection structure 1 provided in the first embodiment of the present application, the switching between the moving locking position and the moving releasing position is achieved by translating the moving locking member 113 to limit or allow the pivot arm 112 to pivot, thereby providing a bracket connection structure 1 with a simple structure and easy state change.

[0211] Figures 4 to 6 The schematic diagrams of the structure of the child carrier according to the first embodiment of the present application from the unfolded state to the folded state are shown respectively. The child carrier applies the bracket connection assembly 10 provided in the first embodiment.

[0212] like Figures 4 to 6 As shown, the child carrier is, for example, a crib, a children's playbed, etc. The child carrier may include a bed frame 1000 and an enclosure not shown, the enclosure may be made of fabric, and the enclosure is connected to the bed frame 1000 to define a storage space for the child carrier, and the child may sleep or play in the storage space. The bed frame 1000 includes an armrest frame 100 and a plurality of support legs 200 for supporting the armrest frame 100. The armrest frame 100 includes a pair of first armrest frames 110 and a pair of second armrest frames 120 adjacent to the first armrest frames 110, the adjacent first armrest frames 110 and the second armrest frames 120 are respectively connected by corner connectors 130, one end of each support leg 200 is connected to the armrest frame 100 by the corner connector 130, and the other end of each support leg 200 is provided with a roller to facilitate the movement of the child carrier.

[0213] Furthermore, if Figures 4 to 6 As shown, each first handrail frame 110 includes two groups of rotating arms 102a, 102b, and each group of rotating arms 102a, 102b includes a first rotating arm 102a and a second rotating arm 102b. The facing ends of the two first rotating arms 102a are respectively pivotally connected to the connecting seat 101, and the opposite ends of the two first rotating arms 102a are respectively connected to the corresponding corner connecting members 130. The facing ends of the two second rotating arms 102b of the first handrail frame 110 are respectively pivotally connected to the connecting seat 101, and the opposite ends of the two second rotating arms 102b of the first handrail frame 110 are respectively connected to the corresponding corner connecting members 130. The second rotating arm 102b is located above the first rotating arm 102a.

[0214] The two first rotating arms 102a of the first handrail frame 110 are respectively connected to the adjacent supporting feet 200 through the connecting rod 140, so that when the bed frame 1000 is folded, the two supporting feet 200 adjacent to each first handrail frame 110 can approach each other. Specifically, the supporting feet 200 are provided with a sliding member 400, and the sliding member 400 is slidably mounted on the supporting feet 200. One end of the connecting rod 140 is rotatably connected to the sliding member 400, and the other end of the connecting rod 140 is rotatably connected to the adjacent first rotating arm 102a, so that when the bed frame 1000 is folded, the two supporting feet 200 adjacent to each first handrail frame 110 can approach each other in the first direction D1. The first rotating arm 102a of the first handrail frame 110 is provided with an inner concave surface 104, and the inner concave surface 104 can prevent the connecting rod 140 from protruding too much from the first rotating arm 102a after the handrail frame 100 is folded.

[0215] Correspondingly, each second armrest frame 120 includes two groups of rotating arms 102a, 102b, and each group of rotating arms 102a, 102b is respectively a first rotating arm 102a and a second rotating arm 102b. The facing ends of the two first rotating arms 102a of the second armrest frame 120 are respectively pivotally connected to the connecting seat 101, and the facing ends of the two second rotating arms 102b of the second armrest frame 120 are respectively pivotally connected to the connecting seat 101. The two first rotating arms 102a of the second armrest frame 120 are respectively connected to the supporting feet 200 adjacent thereto through the connecting rod 140, so as to allow the two supporting feet 200 adjacent to each second armrest frame 120 to be close to each other when the bed frame 1000 is folded. Specifically, one end of the connecting rod 140 is rotatably connected to the first rotating arm 102a, and the other end of the connecting rod 140 is rotatably connected to the sliding member 400. Among them, two adjacent first rotating arms 102a connected to the same corner connector 130 are connected to the same sliding member 400 through different connecting rods 140 respectively, so that when the bed frame 1000 is folded, by folding the armrest frame 100 along one direction (the first direction D1 or the second direction D2), multiple supporting legs 200 can be driven to approach each other in the first direction D1 and the second direction D2 at the same time. The first rotating arm 102a of the second armrest frame 120 is provided with an inner concave surface 104, which can prevent the connecting rod from protruding too much from the first rotating arm 102a after the armrest frame 100 is folded.

[0216] The child carrier provided in the embodiment of the present application realizes switching between a folded state and an unfolded state by providing a foldable first armrest 110 and a second armrest 120. Furthermore, the first armrest 110 and the second armrest 120 are respectively connected to adjacent support legs 200 through a connecting rod 140, so that when the child carrier is unfolded or folded, the multiple support legs 200 of the child carrier can move away from or close to each other, thereby realizing rapid unfolding or folding of the child carrier, which is convenient for the user to operate.

[0217] like Figure 4 As shown, the bed frame 1000 is equipped with the above-mentioned multiple support connection components 10. The support connection components 10 include multiple mobile connection components 11, and the multiple mobile connection components 11 serve as the first armrest frame 110 and the second armrest frame 120 respectively. Specifically, the two groups of first rotating arms 102a and the second rotating arms 102b of each first armrest frame 110 correspond to the two groups of pivot arms 112 (i.e., the first pivot arm 112a and the second pivot arm 112b) of the mobile connection component 11, and the connection seat 101 of each first armrest frame 110 corresponds to the pivot seat 111 of the mobile connection component 11. Similarly, the two groups of first rotating arms 102a and the second rotating arms 102b of each second armrest frame 120 correspond to the two groups of pivot arms 112 (i.e., the first pivot arm 112a and the second pivot arm 112b) of the mobile connection component 11, and the connection seat 101 of each second armrest frame 120 corresponds to the pivot seat 111 of the mobile connection component 11.

[0218] According to the first embodiment of the present application, a support connection structure 1 is also provided. The support connection structure 1 includes a plurality of support connection assemblies 10, an angle connector 130, a support leg 200 and a plurality of connecting rods 140. The plurality of support connection assemblies 10 are connected to the angle connector 130, and the support leg 200 is connected to the angle connector 130. At least one rotating arm 102a / 102b of each support connection assembly 10 is connected to the sliding structure through the connecting rod 140, so that when at least one rotating arm of one of the support connection assemblies 10 rotates, at least one rotating arm of other support connection assemblies 10 can be driven to rotate through the connecting rod 140 and the sliding structure. In this embodiment, the plurality of support connection assemblies 10 are respectively adjacent first handrails 110 and second handrails 120. The sliding structure includes a sliding member 400 slidably disposed on the support leg 200, and the first handrail 120 and the second handrail 120 are respectively connected to the same sliding member 400 through the connecting rod 140. In other embodiments not shown, the sliding structure may include, for example, a sliding groove and a sliding pin inserted into the sliding groove, and the first armrest 110 and the second armrest 120 are respectively connected to the same sliding pin 400 via a connecting rod 140, which is not limited in the present application.

[0219] like Figures 4 to 6When you need to fold the baby bed (child carrier), refer to Figure 4 , press the connecting piece 115 of the movable connecting assembly 11 arranged at a pair of first handrails 110 (or the second handrail 120) along the MD2 direction, and through the driving connection between the connecting piece 115 and the two movable locking pieces 113, drive the two movable locking pieces 113 from the movable locking position to the movable releasing position to allow the two first rotating arms 102a and the two second rotating arms 102b of the first handrail 110 to pivot. At this time, since the movable connecting component 11 configured at the second handrail frame 120 (or the first handrail frame 110) is still in a locked state, the sliding member 400 cannot move downward (i.e., away from the corner connecting member 130) or can only move a very small distance. Therefore, the two first rotating arms 102a and the two second rotating arms 102b of the first handrail frame 110 (or the second handrail frame 120) can only be slightly folded to restrict the two movable locking members 113 of the movable connecting component 11 configured at the first handrail frame 110 (or the second handrail frame 120) to be restricted in the movable unlocking position. Then, the connecting member 115 of the movable connecting assembly 11 disposed at the pair of second handrail frames 120 (or the first handrail frame 110) is pressed along the MD2 direction, and the two movable locking members 113 are driven to move from the movable locking position to the movable unlocking position through the driving connection between the connecting member 115 and the two movable locking members 113, so as to allow the two first rotating arms 102a and the two second rotating arms 102b of the second handrail frame 120 to pivot. At this time, referring to Figure 5 When the user further folds one of the first armrest 110 and the second armrest 120, one of the connecting rods 140 drives the sliding member 400 to move downward, and the downward movement of the sliding member 400 can drive the other connecting rod 140 to move downward, thereby driving the other of the first armrest 110 and the second armrest 120 to fold, so that the multiple supporting legs 200 are simultaneously close to each other along the D1 direction and the D2 direction, and the first armrest 110 and the second armrest 120 can be folded at the same time, thereby realizing the rapid folding of the child carrier (refer to Figure 6 ). It can be understood that the child carrier of the present embodiment includes a pair of first armrests 110 and a pair of second armrests 120. When the movable connection components 11 in the pair of first armrests 110 and the pair of second armrests 120 are both in the unlocked state, the folding operation of any one of the first armrests 110 or any one of the second armrests 120 is continued. Through the linkage relationship between the first rotating arm 102a, the plurality of connecting rods 140 and the four sliding members 400, the pair of first armrests 110 and the pair of second armrests 120 can be folded at the same time.

[0220] When you need to unfold the crib, refer to Figure 6, the two first rotating arms 102a and the two second rotating arms 102b of one of the first armrests 110 (or the second armrests 120) can be pivoted to rotate the two from the folded position to the unfolded position, and the sliding member 400 is driven to move upward (i.e., close to the direction of the corner connecting member 130) through the connecting rod 140, thereby driving the two first rotating arms 102a and the two second rotating arms 102b of the corresponding second armrest 120 (or the first armrest 110) to unfold through another connecting rod 140 connected to the sliding member 400, thereby realizing the synchronous unfolding of the two first armrests 110 and the two second armrests 120, and then realizing the unfolding of the child carrier (refer to Figure 4 ).

[0221] It is understandable that when the crib is in the folded state (see Figure 6 ), the two groups of rotating arms 102a and 102b of the first armrest frame 110 will rotate to extend substantially vertically (i.e. rotate to be substantially perpendicular to the moving direction MD1 of the two locking members 113), and will be located on both sides of the two moving locking members 113, and will push the two moving locking members 113 to approach each other and compress the moving reset member 114, restricting the two moving locking members 113 from sliding to the moving locking positions. When the baby bed is gradually unfolded to the unfolded state, the two groups of rotating arms 102a and 102b of the first armrest frame will gradually rotate to extend substantially horizontally (i.e. rotate to be substantially parallel to the moving direction MD1 of the two locking members 113), during which the restricting force of the two groups of rotating arms 102a and 102b of the first armrest frame 110 on the two moving locking members 113 will be weakened, and the two moving locking members 113 will automatically move from the moving unlocking position to the moving locking position under the elastic restoring force of the moving reset member 114, thereby locking the baby bed in the unfolded state. The second handrail frame 120 also has a similar process, which will not be described here. It can be understood that in the process of the second rotating arm 102b (second pivoting arm 112b) gradually rotating to horizontal extension, its limiting force on the movable locking member 113 gradually weakens, and under the elastic restoring force of the movable reset member 114, the second rotating arm 102b (second pivoting arm 112b) will rotate and slide against the guide surface 1135, and the guide surface 1135 is arc-shaped.

[0222] According to the child carrier provided in the first embodiment of the present application, the child carrier can be quickly folded or unfolded by configuring a bracket connection structure, and the structure is simple and easy to operate.

[0223] Figures 7 to 9The structural schematic diagram of the support connection structure 1 provided according to the second embodiment of the present application is shown. The support connection structure 1 is provided with two support connection components 10. Both support connection components 10 are movable connection components 11, namely, a first movable component 11a and a second movable component 11b. The two movable connection components 11 are driven and connected by a linkage 20, so that when one of the movable connection components 11 is operated, the other movable connection component 11 can be driven to switch between a locked state and a released state at the same time, thereby realizing that the two movable connection components 11 that are linked to each other can switch their states at the same time.

[0224] like Figures 7 to 9 As shown, each mobile connection assembly 11 includes a pivot seat 111, at least one group of pivot arms 112, at least one mobile locking member 113, and a mobile reset member 114 suitable for biasing the mobile locking member 113 to move the mobile locking member 113 to the mobile locking position. In this embodiment, each mobile connection assembly 11 is configured with two groups of pivot arms 112 and two mobile locking members 113. The two mobile locking members 113 act on different groups of pivot arms 112 respectively to limit or allow the pivot arms 112 to rotate relative to the pivot seat 111. The mobile reset member 114 is connected to the two mobile locking members 113 respectively to bias the two mobile locking members 113 to move the two mobile locking members 113 to the mobile locking position respectively. Figures 7 to 9 As shown, each movable connection assembly 11 is further provided with a connecting member 115 , and the connecting member 115 is drivingly connected to the two movable locking members 113 respectively.

[0225] Furthermore, each set of pivot arms 112 includes a first pivot arm 112a and a second pivot arm 112b respectively pivoted to the same side of the pivot seat 111, and the first pivot arm 112a and the second pivot arm 112b are arranged at intervals. In this embodiment, the first pivot arm 112a is located below the second pivot arm 112b. When the movable locking member 113 is in the movable locking position, the movable locking member 113 abuts against the first pivot arm 112a and the second pivot arm 112b respectively to limit the first pivot arm 112a and the second pivot arm 112b from pivoting; when the movable locking member 113 is in the movable unlocking position, the first pivot arm 112a and the second pivot arm 112b can rotate relative to the pivot seat 111.

[0226] In this embodiment, the support connection structure 1 is different from the support connection structure 1 in the first embodiment at least in the following aspects.

[0227] Figure 10 to Figure 11The structural schematic diagrams of the connecting member 115a of the first moving component 11a and the connecting member 115b of the second moving component 11b are respectively shown. The connecting member 115a of the first moving component 11a is provided with an operable operating portion 1153, while the connecting member 115b of the second moving component 11b is not provided with the operating portion 1153, so that the user can only drive the two moving connection components 11 to switch synchronously from the locked state to the unlocked state by operating the connecting member 115a of the first moving component 11a. In some embodiments, referring to Fig.10 The operating portion 1153 of the connecting member 115a is further provided with a reinforcing rib 1154, so as to enhance the strength of the operating portion 1153. The reinforcing rib 1154 is connected to the bottom wall 1156 of the clearance groove 1151, and is substantially parallel to a pair of side walls of the clearance groove 1151.

[0228] Combined with reference Figures 7 to 9 , the connecting member 115 is provided with a driving groove 116, and the driving groove 116 is in a strip shape. The extending direction of the driving groove 116 is at an angle to the moving directions MD1 and MD2 of the movable locking member 113 and the connecting member 115. The driving groove 116 is configured as two, and the two driving grooves 116 are symmetrically distributed on the side walls 1157 of the first make way groove 1151a and the second make way groove 1151b. The connecting member 115 is connected with a driving member, and the driving member and the driving groove 116 are slidably matched to drive the movable locking member 113 to switch between the movable locking position and the movable unlocking position. Specifically, each movable locking member 113 is provided with a driving protrusion 117, and the driving protrusion 117 and the movable locking member 113 are integrally formed components. In the present embodiment, the driving protrusion 117 is formed as a driving member. Each driving protrusion 117 is plug-fitted with the corresponding driving groove 116 to realize the driving connection between the movable locking member 113 and the connecting member 115. It is understandable that the movable locking member 113 may be provided with a driving groove 116 , and the connecting member 115 may be provided with a driving protrusion 117 , and the driving protrusion 117 may be plugged into and matched with the driving groove 116 to achieve a driving connection between the movable locking member 113 and the connecting member 115 .

[0229] Of course, in some other embodiments, each movable locking member 113 may be provided with a driving slot 116 (eg Figure 1), two connecting through holes 1155 are correspondingly provided on the connecting member 115, and the connecting through holes 1155 penetrate a pair of side walls of the yielding groove 1151. A guide hole 1116 is provided on the pivot seat 111, and the guide hole 1116 is, for example, a bar hole, and the extending direction of the guide hole 1116 is substantially parallel to the moving direction MD2 of the connecting member 115. The connecting member 115 is driven and connected to the two movable locking members 113 respectively through the driving pin 118 penetrated in the guide hole 1116, the connecting through hole 1155 and the driving groove 116, and is movably connected to the pivot seat 111. The driving pin 118 can be, for example, a rivet, a screw, a bolt, etc. In other embodiments not shown, the connecting member 115 can also be provided with a driving groove 116, the movable locking member 113 can be provided with a connecting through hole 1155, and the pivot seat 111 can be provided with a guide hole 1116. The guide hole 1116 is a strip hole extending substantially parallel to the moving direction of the movable locking member 113. The guide hole 1116 can be connected to the slide slot 1111, or can be the slide slot 1111. The connecting member 115 is driven and connected to the two movable locking members 113 respectively through the driving pin 118 penetrating the guide hole 1116, the driving slot 116 and the connecting through hole 1155.

[0230] Figure 12 to Figure 13The structural schematic diagram of the movable locking member 113 provided according to the second embodiment of the present application is shown. The movable locking member 113 is roughly an L-shaped block structure. The movable locking member 113 includes a first portion 11301 and a second portion 11302 arranged on the first portion 11301, the first portion 11301 forms a first surface 1131 suitable for abutting against the first pivot arm 112a, and the second portion 11302 forms a second surface 1132 suitable for abutting against the second pivot arm 112b, and the first surface 1131 is roughly parallel to the second surface 1132. When the movable locking member 113 is located at the movable locking position, the first pivot arm 112a is stopped by the first surface 1131, and the second pivot arm 112b is stopped by the second surface 1132, so that the first pivot arm 112a and the second pivot arm 112b are restricted from rotating relative to the pivot seat 111. When the movable locking member 113 is located at the movable unlocking position, the first pivot arm 112a is staggered with the first surface 1131, and the second pivot arm 112b is staggered with the second surface 1132, so as to allow the first pivot arm 112a and the second pivot arm 112b to rotate relative to the pivot seat 111. In this embodiment, when the movable locking member 113 is located at the movable locking position, the first pivot arm 112a is in contact with the first surface 1131, and the second pivot arm 112b is in contact with the second surface 1132. When the movable locking member 113 is located at the movable unlocking position, the first pivot arm 112a is separated from the first surface 1131, and the second pivot arm 112b is separated from the second surface 1132. By the first pivot arm 112a being in contact with the first surface 1131, and the second pivot arm 112b being in contact with the second surface 1132, the bracket connection structure 1 is made more stable. An avoidance recess 11303 is formed between the first portion 11301 and the second portion 11302 to allow the second surface 1132 to be offset from the second pivot arm 112b when the movable locking member 113 is in the movable unlocking position, so that the second pivot arm 112b can rotate relative to the pivot seat 111. Compared with the first embodiment, in this embodiment, the movable locking member 113 may not be provided with the guide surface 1135, and an arc chamfer may be provided at the edge of the second surface 1132 adjacent to the second pivot arm 112b.

[0231] like Figures 7 to 9 As shown, the two ends of the linking member 20 are respectively connected to the moving locking members 113 of the two moving connection components 11, so that the moving locking members 113 of the two moving connection components 11 can be synchronously switched between the moving locking position and the moving unlocking position. Among them, one end of the linking member 20 is connected to the second moving locking member 113b of the first moving component 11a, and the other end of the linking member 20 is connected to the second moving locking member 113b of the second moving component 11b.

[0232] Fig.14A schematic diagram of the structure of a linkage 20 provided according to a second embodiment of the present application is shown, wherein the linkage 20 includes a traction rope 21, a first stop end 22a and a second stop end 22b respectively arranged at both ends of the traction rope 21, and a sheath 23 sleeved on the outside of the traction rope 21. The first stop end 22a and the second stop end 22b have the same structure. The sheath 23 is arranged outside the traction rope 21. At least a portion of the traction rope 21, the first stop end 22a, and the second stop end 22b all extend out of the sheath 23. A first connecting end 24a suitable for the traction rope 21 to pass through is provided at one end of the sheath 23, and a second connecting end 24b suitable for the traction rope 21 to pass through is provided at the other end of the sheath 23. Combined with reference Figures 7 to 9 The first connecting end 24a is limited to the pivot seat 111 of the first moving component 11a, and the second connecting end 24b is limited to the pivot seat 111 of the second moving component 24a.

[0233] Combined with reference Figures 7 to 9 ,as well as Fig.12 and Fig.13 , the movable locking member 113 is provided with a snap-in hole 1137 suitable for the traction rope 21 to pass through, and the first snap-in end 22a and the second snap-in end 22b are snap-in with the corresponding snap-in holes 1137 respectively. Specifically, the first movable locking member 113a and the second movable locking member 113b of each movable connecting assembly 11 are provided with a snap-in hole 1137. The first snap-in end 22a is snap-in with the snap-in hole 1137 of the second movable locking member 113b of the first movable assembly 11a, and the second snap-in end 22b is snap-in with the snap-in hole 1137 of the second movable locking member 113b of the second movable assembly 11b. The traction rope 21 passes through the snap-in hole 1137 of the second movable locking member 113b of the first movable assembly 11a, the snap-in hole 1137 of the first movable locking member 113a of the second movable assembly 11b, the movable reset member 114, and the snap-in hole 1137 of the second movable locking member 113b of the second movable assembly 11b in sequence. The traction rope 21 may be, for example, a steel rope, a carbon fiber rope, etc. It is understood that in some other embodiments not shown, the first movable locking member 113a of the first movable assembly 11a may not be provided with the engaging hole 1137, and the first movable locking member 113a of the second movable assembly 11b may not be provided with the engaging hole 1137, and the present application does not limit this.

[0234] like Figure 12 to Figure 13 As shown, the engaging hole 1137 is disposed in the second portion 11302 of the movable locking member 113, and one end of the engaging hole 1137 is connected to the receiving groove 1136 of the movable locking member 113. In some embodiments, an abutment portion 1138 is disposed in the engaging hole 1137. Figure 7, the first stop end 22a and the second stop end 22b are adapted to respectively abut against the abutment portion 1138 in the corresponding engaging hole 1137, so as to realize the engagement of the first stop end 22a and the second stop end 22b with the corresponding engaging hole 1137. In the present embodiment, the abutment portion 1138 is located at one end of the engaging hole 1137 away from the receiving groove 1136. In the present embodiment, the abutment portion 1138 is provided at the edge of the corresponding second movable locking member 113b away from the receiving groove 1136, and the first stop end 22a is at least partially accommodated in the engaging hole 1137 of the second movable locking member 113b of the first movable assembly 11a, and abuts against the abutment portion 1138 of the second movable locking member 113b of the first movable assembly 11a. The second stopper end 22b is located outside the engagement hole 1137 of the second moving locking member 113b of the second moving assembly 11b, and abuts against the abutment portion 1138 of the second moving locking member 113b of the second moving assembly 11b. Of course, in other embodiments, the position of the abutment portion 1138 on the second moving locking member 113b can be changed to adjust the relative positions between the first stopper end 22a, the second stopper end 22b and the corresponding second moving locking member 113b, and it is not limited to setting the abutment portion 1138 at the edge of the second moving locking member 113b away from the receiving groove 1136.

[0235] like Fig.12 and Fig.13 As shown, in some embodiments, the movable locking member 113 is further provided with a mounting through hole 1139 suitable for the first locking end 22a and the second locking end 22b to pass through, the mounting through hole 1139 is provided in the second portion 11302, and one end of the mounting through hole 1139 is communicated with the receiving groove 1136. The mounting through hole 1139 is communicated with the engaging hole 1137 to allow the traction rope 21 to move between the mounting through hole 1139 and the engaging hole 1137. When the linkage member 20 needs to be installed, the first locking end 22a and the second locking end 22b can be respectively passed through the corresponding mounting through holes 1139, and then the traction rope 21 is moved into the engaging hole 1137, and the first locking end 22a and the second locking end 22b are respectively engaged with the corresponding abutment portions 1138. When the linking member 20 needs to be disassembled, the first stop end 22a, the second stop end 22b and the traction rope 21 can be first moved from the engagement hole 1137 to the installation through hole 1139, and then the first stop end 22a and the second stop end 22b are passed out from the corresponding installation through hole 1139. By providing the installation through hole 1139 connected to the engagement hole 1137, the linking member 20 can be easily disassembled.

[0236] Furthermore, if Figures 7 to 9As shown, the pivot seat 111 of the mobile connection assembly 11 is provided with a fixing frame 119, and the traction rope 21 of the linkage 20 can pass through the fixing frame 119. The fixing frame 119 is located in the receiving groove 1113 of the pivot seat 111. The fixing frame 119 is formed by tearing a part of the side wall 1115 of the pivot seat 111 and bending inward (i.e., in the direction of the receiving groove 1113). The fixing frame 119 and the pivot seat 111 are an integral component, thereby improving the connection strength between the fixing frame 119 and the pivot seat 111, while reducing the manufacturing cost. It can be understood that in other embodiments, the fixing frame 119 can also be a component fixed to the side wall 1115 of the pivot seat 111 by, for example, welding, riveting, bonding, etc., and this application is not limited to this.

[0237] Continue to refer to Figures 7 to 9 , the pivot seat 111 is provided with a fixing frame 119. The fixing frame 119 is formed by partially tearing and bending one of the side walls 1115 of the pivot seat 111 inward. In the first moving assembly 11a, the fixing frame 119 is arranged close to the second moving locking member 113b, and is located at the avoidance recess 11303 of the second moving locking member 113b. In the second moving assembly 11b, the fixing frame 119 is arranged close to the first moving locking member 113a, and is located at the avoidance recess 11303 of the first moving locking member 113a. The first connecting end 24a is limited to the fixing frame 119 of the first connecting assembly, and the second connecting end 24b is limited to the fixing frame 119 of the second connecting assembly. Specifically, the first connecting end 24a abuts against the fixing frame 119 of the first connecting assembly, and the second connecting end 24b abuts against the fixing frame 119 of the second connecting assembly. The first stopper end 22a and the first connecting end 24a are respectively located on both sides of the fixing frame 119, and the second stopper end 22b and the second connecting end 24b are respectively located on both sides of the fixing frame 119. In other embodiments, the fixing frame 119 can be formed by partially tearing and bending the two side walls 1115 of the pivot seat 111 inward. The pivot seat 111 can be configured with a plurality of fixing frames 119, for example, two fixing frames 119 can be configured. The two fixing frames 119 are respectively a first fixing frame 119a arranged near the first moving locking member 113a and a second fixing frame 119b arranged near the second moving locking member 113b. The first connecting end 24a of the linking member 20 abuts against the second fixing frame 119b of the first moving assembly 11a, and the second connecting end 24b of the linking member 20 abuts against the first fixing frame 119a of the second moving assembly 11b. It is understandable that in other embodiments not shown, the pivot seat 111 of one of the first movable component 11a and the second movable component 11b may be configured with one fixed frame 119, and the other of the first movable component 11a and the second movable component 11b may be configured with two fixed frames 119, and the present application does not impose any limitation on this.

[0238] According to the support connection structure 1 provided in the second embodiment of the present application, the operating part 1153 of the first moving component 11a is operated to move the first moving locking member 113a and the second moving locking member 113b of the first moving component 11a from the locking position to the unlocking position, and the second moving locking member 113b of the second moving component 11b is driven to move synchronously from the locking position to the unlocking position through the linkage 20. The movement of the second moving locking member 113b of the second moving component 11b will drive the connecting member 115b of the second moving component 11b to move, and then drive the first moving locking member 113a of the second moving component 11b to move from the locking position to the unlocking position, so that the pivot arms 112 of the two moving connection components 11 can rotate relative to the pivot seat 111. The support connection structure 1 provided in this embodiment has a simple structure and is easy to operate.

[0239] Fig.15 A schematic diagram of the structure of a child carrier provided according to a second embodiment of the present application is shown. The child carrier includes a bed frame 1000 and an enclosure not shown, which may be made of fabric. The enclosure is connected to the bed frame 1000 to define a storage space for the child carrier, and the child may sleep or play in the storage space. The bed frame 1000 includes a plurality of handrails 100 and a plurality of supporting legs 200 for supporting the handrails 100. The handrail 100 includes a pair of first handrails 110 and a pair of second handrails 120 adjacent to the first handrails 110. The child carrier of this embodiment differs from the child carrier provided in the first embodiment described above in at least the following ways.

[0240] like Fig.15 As shown, the bed frame 1000 is equipped with a support connection assembly 10 of the support connection structure 1 provided in the second embodiment. The support connection assembly 10 includes a first moving assembly 11a and a second moving assembly 11b. The first moving assembly 11a serves as a first armrest frame 110, and the second moving assembly 11b serves as a second armrest frame 120. Specifically, the two groups of first rotating arms 102a and the second rotating arms 102b of each first armrest frame 110 correspond to the two groups of pivot arms 112 of the first moving assembly 11a (i.e., the first pivot arm 112a and the second pivot arm 112b), respectively. The connecting seat 101 of each first armrest frame 110 corresponds to the pivot seat 111 of the first moving assembly 11a. The two groups of first rotating arms 102a and the second rotating arms 102b of each second armrest frame 120 correspond to the two groups of pivot arms 112 of the second moving assembly 11b (i.e., the first pivot arm 112a and the second pivot arm 112b), respectively. The connecting seat 101 of each second armrest frame 120 corresponds to the pivot seat 111 of the second moving assembly 11 b .

[0241] In this embodiment, the support connection structure 1 further includes an angle connector 130, a support leg 200 and a connecting rod 140. The first armrest frame 110 and the second armrest frame 120 are connected to the angle connector 130, and the support leg 200 is connected to the angle connector 130. A slidable sliding member 400 is provided on the support leg 200, and the first armrest frame 120 and the second armrest frame 120 are respectively connected to the same sliding member 400 through the connecting rod 140. The first armrest frame 110 and the second armrest frame 120 are driven and connected by a linkage 20.

[0242] When you need to fold the child carrier, refer to Figure 7 , pressing the connecting member 115a of the first moving assembly 11a along the MD2 direction, driving the two moving locking members 113 of the first moving assembly 11a to move Figure 7 Move the lock position shown to Figure 8 At the same time, the second moving locking member 113b of the first moving assembly 11a drives the second moving locking member 113b of the second moving assembly 11b to move to the moving unlocking position through the linkage 20, and the first moving locking member 113a of the second moving assembly 11b is driven to move to the moving unlocking position through the driving connection between the connecting member 115b and the two moving locking members 113. In other words, the connecting member 115a of the first moving assembly 11a is operated to make the two moving connection assemblies 11a switch to the unlocking state synchronously. Therefore, when the child carrier needs to be folded, it is only necessary to operate the two operating parts on the two first armrests 110 to release the two first armrests 110 and the two second armrests 120, and continue to press the connecting members 115a on the two first armrests 110 to maintain the two movable connecting components 11 in the unlocked state. At this time, a downward force along the MD2 direction is applied to the pivot seat 111 of any first armrest 110. Driven by the sliding member 400, the two first armrests 110 and the two second armrests 120 can be folded synchronously, thereby realizing the folding of the child carrier without operating the four pivot seats 111 one by one.

[0243] The unfolding process of the child carrier in this embodiment is basically the same as that of the first embodiment described above. When the two sets of rotating arms 102a and 102b of the two first armrests 110 and the two second armrests 120 gradually rotate to a horizontal state, the movable locking member 113 gradually moves to a movable locking position, which will not be repeated here.

[0244] According to a third embodiment of the present application, a support connection structure 1 and a child carrier equipped with the support connection structure 1 are provided.

[0245] Figures 16 to 201 is a schematic diagram of the structure of a support connection assembly 10 of a support connection structure 1 provided in accordance with the third embodiment of the present application. The support connection assembly 10 includes a rotating connection assembly 12. The rotating connection assembly 12 includes a rotating seat 121, a first rotating arm 122a, a second rotating arm 122b and a rotating locking member 123, and the rotating locking member 123 serves as a locking member of the support connection assembly 10. The first rotating arm 122a is pivotally connected to the rotating seat 121, and the second rotating arm 122b is pivotally connected to the rotating seat 121. The first rotating arm 122a and the second rotating arm 122b both have an unfolded position (refer to Fig.18 ) and folded position (refer to Fig.19 ). When the rotation locking member 123 is located at the rotation unlocking position, the rotation connection assembly 12 is in the unlocking state, the first rotation arm 122a is rotatable relative to the rotation seat 121, and the second rotation arm 122b is rotatable relative to the rotation seat 121. When the rotation locking member 123 is located at the rotation locking position, the rotation connection assembly 12 is in the locking state, and the first rotation arm 122a is restricted from rotating relative to the rotation seat 121. In some embodiments not shown, the rotation connection assembly 12 may not be configured with the second rotation arm 122b, and this application does not limit this.

[0246] like Figure 16 to Figure 17 As shown, the rotating seat 121 includes a receiving groove 1212 suitable for receiving the rotating locking member 123, and the receiving groove 1212 is surrounded by a top wall 1214 and a pair of side walls 1213 connected to opposite sides of the top wall 1214. The end of the rotating arm 122 is received in the receiving groove 1212, and is pivotally connected to the pair of side walls 1213 of the rotating seat 121 through a pin (not shown in the drawings), such as a rivet, a screw, a bolt, etc. Among them, the second rotating arm 122b is closer to the top wall 1214 of the pivot seat 111 than the first rotating arm 122a, that is, the second rotating arm 122b is located above the first rotating arm 122a.

[0247] Further, refer to Fig. 20 The first rotating arm 122a and the second rotating arm 122b are respectively pivotally connected to the side wall 1213 of the rotating seat 121 through a pin (for example, a rivet, a screw, a bolt, etc.). The first rotating arm 122a rotates relative to the rotating seat 121 about the rotating axis Y1-Y1, and the second rotating arm 122b rotates relative to the rotating seat 121 about the rotating axis Y2-Y2. The rotating axes Y1-Y1 and Y2-Y2 are substantially parallel, and the rotating axis Y2-Y2 is located above the rotating axis Y1-Y1. The rotating locking member 123 is rotatably disposed on the rotating seat 121 and can be switched between a rotating unlocking position and a rotating locking position.

[0248] like Fig.17 , Fig. 20As shown, the rotation locking member 123 is provided with a pivot hole 1234, and a pivot shaft (not shown in the drawings) is passed through the pivot hole 1234 and connected to a pair of side walls 1213 of the rotating seat 121. The pivot shaft can be a protrusion provided on the side wall of the rotating seat 121, or a pin connected to the side wall of the rotating seat 121. The pivot axis RR of the rotation locking member 123 relative to the rotating seat 121 is substantially parallel to the pivot axis Y1-Y1 or the pivot axis Y2-Y2. The rotation locking member 123 is provided with a hook body portion 1238, and the hook body portion 1238 forms a clamping recess 1231. The first rotating arm 122a is provided with a clamping protrusion 1221. When the rotation locking member 123 is located at the rotation locking position, the clamping protrusion 1221 is clamped with the clamping recess 1231. When the rotation locking member 123 is located at the rotation unlocking position, the clamping protrusion 1221 is released from the clamping recess 1231. In some embodiments, the rotation locking member 123 forms a clamping recess 1231 facing the first rotating arm 122a. The end of the first rotating arm 122a forms the clamping protrusion 1221. The first rotating arm 122a is also provided with a clamping surface 1222. When the rotation locking member 123 is located at the rotation locking position, the end of the first rotating arm 122a is accommodated in the clamping recess 1231, and the clamping surface 1222 can abut against the side wall of the clamping recess 1231. The provision of the engaging surface 1222 increases the contact area between the first rotating arm 122a and the engaging recess 1231, so that the first rotating arm 122a and the rotating locking member 123 can be more firmly engaged. Figures 17 to 19 As shown, the engaging surface 1222 includes a concave surface formed by the side concave of the end of the first rotating arm 122a. In some embodiments, the hook body 1238 of the rotating locking member 123 is further provided with a wedge surface 1239. Fig.19 The unlocked state shown is Fig.17 When the locking state is switched, the end of the first rotating arm 122a pushes against the wedge surface 1239 to rotate the rotating locking member 123, so as to allow the end of the first rotating arm 122a to be engaged in the engaging recess 1231. According to the bracket connection assembly 10 provided in the third embodiment of the present application, the rotating locking member 123 is pivotally disposed on the rotating seat 121, so as to realize the switching of the rotating locking member 123 between the rotating locking position and the rotating unlocking position, so as to restrict or allow the first rotating arm 122a to rotate relative to the rotating seat 121.

[0249] In some embodiments, Fig.17As shown, the rotating connection assembly 12 is provided with two first rotating arms 122a, two second rotating arms 122b and two rotating locking members 123. The two first rotating arms 122a are respectively pivotally connected to the rotating seat 121 at positions adjacent to the facing ends. The two rotating locking members 123 are adapted to respectively engage with the corresponding first rotating arms 122a to limit or allow the first rotating arms 122a to rotate. The two rotating locking members 123 are drivingly connected, and specifically, the two rotating locking members 123 are respectively provided with a plurality of meshing teeth 1232 that can mesh with each other. The meshing teeth 1232 mesh with each other, so that when one of the rotating locking members 123 rotates, the other rotating locking member 123 can be driven to rotate synchronously, so that the two rotating locking members 123 can be synchronously switched between the rotation locking position and the rotation releasing position.

[0250] like Figures 17 to 19 As shown, the rotating connection assembly 12 also includes a rotation reset member 124, which biases one of the rotating locking members 123 to rotate the rotating locking member 123 to the rotation locking position, and drives the other rotating locking member 123 to rotate to the rotation locking position through the meshing teeth 1232. The rotation reset member 124 is, for example, a torsion spring. The rotation reset member 124 is sleeved on the pivot shaft of one of the rotating locking members 123, and one end of the rotation reset member 124 abuts against the rotating locking member 123, and the other end of the rotation reset member 124 abuts against the pin shaft (not shown in the drawings) on the first rotating arm 122a. It should be noted that in this embodiment, only one rotation reset member 124 is configured for one of the rotating locking members 123, and in other embodiments, the two rotating locking members 123 can also be configured with rotation reset members 124, respectively, and this application does not limit this.

[0251] See also Fig.16 , Fig. 20 and Fig.21 , a schematic diagram of the structure of an operating member 125 provided according to a third embodiment of the present application is shown. The rotating connection assembly 12 is provided with an operating member 125, which is rotatably disposed on the rotating seat 121 and is drivingly connected to the rotating locking member 123 to drive the rotating locking member 123 to switch between the rotating locking position and the rotating unlocking position. In this embodiment, the number of the operating member 125 is one. The operating member 125 is drivingly connected to one of the rotating locking members 123 to allow the rotating locking member 123 to rotate when the operating member 125 is rotated, and the other rotating locking member 123 is driven to rotate synchronously through the meshing cooperation between the meshing teeth 1232 of the two rotating locking members 123, thereby realizing that the two rotating locking members 123 are synchronously switched between the rotating locking position and the rotating unlocking position.

[0252] Furthermore, if Fig. 20 and Fig.21As shown, one of the rotating locking members 123 is provided with a pivoting protrusion 1235, and the pivoting protrusion 1235 is provided with a recess 1236. The operating member 125 is provided with a connecting column 1251, and the connecting column 1251 forms a pivoting recess 1252 suitable for accommodating the pivoting protrusion 1235. The pivoting recess 1252 is provided with a protrusion 1253 suitable for engaging with the recess 1236, and the protrusion 1253 extends inward from the side wall of the pivoting recess 1252. There are multiple protrusions 1253, and the multiple protrusions 1253 are evenly distributed on the side wall of the pivoting recess 1252. There are also multiple recesses 1236, and the number of recesses 1236 is greater than or equal to the number of protrusions 1253. The side wall of the rotating seat 121 is provided with a through hole 1215, and the pivoting protrusion 1235 is suitable for passing through the through hole 1215 to connect with the operating member 125. In other embodiments, the connecting column 1251 may pass through the through hole 1215 and be connected to the rotating locking member 123 . Fig. 20 and Fig.21 The pivoting protrusion 1235 is at least partially accommodated in the pivoting recess 1252, and the protrusion 1253 is engaged with the recess 1236, so that when the operating member 125 rotates, the rotation locking member 123 is driven to rotate. In order to prevent the operating member 125 and the rotation locking member 123 from being separated from each other, the rotation locking member 123 and the operating member 125 are further connected by a fastener (not shown), which can pass through the center holes of the pivoting protrusion 1235 and the pivoting recess 1252. The fastener can be a screw or a rivet.

[0253] In the bracket connection structure 1 of this embodiment, one of the rotation locking members 123 is driven to rotate by the rotation operating member 125, and the other rotation locking member 123 is driven to rotate by the meshing cooperation of the meshing teeth 1232, so that the two rotation locking members 123 are synchronously switched between the rotation release position and the rotation lock position. Thus, a bracket connection structure 1 with a simple structure and convenient operation is provided.

[0254] Fig. 22 A schematic diagram of the structure of a child carrier provided according to the third embodiment of the present application is shown. The child carrier includes a bed frame 1000 and an enclosure (not shown in the drawings) which is not shown. The enclosure can be made of fabric. After the enclosure is connected to the bed frame 1000, an accommodating space for the child carrier is defined, and the child can sleep or play in the accommodating space. The bed frame 1000 includes an armrest frame 100 and a plurality of supporting legs 200 for supporting the armrest frame 100. The armrest frame 100 includes a pair of first armrest frames 110 and a pair of second armrest frames 120 adjacent to the first armrest frame 110. The child carrier of this embodiment differs from the child carriers provided in the first and second embodiments described above in at least the following ways.

[0255] like Fig. 22As shown, the bed frame 1000 is equipped with a support connection assembly 10. The support connection assembly 10 includes a plurality of rotating connection assemblies 12. The plurality of rotating connection assemblies 12 serve as a first armrest frame 110 and a second armrest frame 120, respectively. Specifically, the two first rotating arms 102a and the two second rotating arms 102b of each first armrest frame 110 correspond to the two first rotating arms 122a and the two second rotating arms 122b of the rotating connection assembly 12, respectively. The connecting seat 101 of each first armrest frame 110 corresponds to the rotating seat 121 of the rotating connection assembly 12. Since the first rotating arm 122a and the second rotating arm 122b located on the same side of the rotating seat 121 are both connected to the same corner connector 130 of the armrest frame 100, when the rotating connection assembly 12 is in a locked state, the first rotating arm 122a is restricted from rotating relative to the rotating seat 121, thereby restricting the second rotating arm 122b from rotating relative to the rotating seat 121. The two groups of first rotating arms 102a and second rotating arms 102b of each second handrail frame 120 correspond to the two groups of rotating arms 122 (i.e., the first rotating arms 122a and the second rotating arms 122b) of the rotating connection assembly 12. The connecting seat 101 of each second handrail frame 120 serves as the rotating seat 121 of the rotating connection assembly 12. According to the third embodiment of the present application, a support connection structure 1 is also provided. The support connection structure 1 includes a plurality of support connection assemblies 10, an angle connector 130, a supporting foot 200 and a plurality of connecting rods 140. The plurality of support connection assemblies 10 are connected to the angle connector 130, and the supporting foot 200 is connected to the angle connector 130. At least one rotating arm 102a / 102b of each support connection assembly 10 is connected to the sliding structure through the connecting rod 140, so that when at least one rotating arm of one of the support connection assemblies 10 rotates, at least one rotating arm of the other support connection assemblies 10 can be driven to rotate through the connecting rod 140 and the sliding structure. In this embodiment, the plurality of bracket connection assemblies 10 are respectively adjacent first handrails 110 and second handrails 120. The sliding structure includes a sliding member 400 slidably disposed on the support foot 200, and the first handrail 120 and the second handrail 120 are respectively connected to the same sliding member 400 through a connecting rod 140. In other embodiments not shown, the sliding structure may include, for example, a sliding groove and a sliding pin inserted into the sliding groove, and the first handrail 110 and the second handrail 120 are respectively connected to the same sliding pin 400 through a connecting rod 140, which is not limited in this application.

[0256] When the child carrier needs to be folded, the rotating operating member 125 needs to be rotated. Since the two rotating locking members 123 have different rotation directions for locking or releasing, the user's operation of the operating member 125 needs to be determined by the rotating locking member 123 to which the operating member 125 is connected. Fig.16 and Fig. 20 , connected with operating member 125 Fig.16Taking the left rotation locking member 123 as an example, a counterclockwise force is applied to the operating member 125 of the rotation connection assembly 12 located on the pair of first handrail frames 110 (or the second handrail frame 120), so that the operating member 125 rotates counterclockwise and drives one of the rotation locking members 123 to rotate counterclockwise, and further drives the other rotation locking member 123 to rotate clockwise through the meshing of the meshing teeth 1232 of the two rotation locking members 123, so that the engaging recesses 1231 of the two rotation locking members 123 rotate in a direction away from the first rotation arm 122a. The operating member 125 is rotated continuously so that the engaging recesses 1231 of the two rotation locking members 123 are completely separated from the end of the first rotation arm 122a (that is, both the two rotation locking members 123 are in the rotation release position). At this time, since the rotating connection assembly 12 configured on the second handrail frame 120 (or the first handrail frame 110) is still in a locked state, the sliding member 400 cannot move downward (i.e., away from the angle connection member 130) or can only move a very small distance, so the two first rotating arms 102a and the two second rotating arms 102b of the first handrail frame 110 or (the second handrail frame 120) can only be slightly folded, so that the ends of the first rotating arms 122a configured on the first handrail frame 110 (or the second handrail frame 120) can restrict the two rotating locking members 123 to the rotation release position. Then, the operating member 125 of the rotating connection assembly 12 configured on the other pair of second handrail frames 120 (or the first handrail frame 110) is rotated in the same way, so that the two rotating locking members 123 of the rotating connection assembly 12 are rotated to the rotation release position. At this time, the first armrest 110 and the second armrest 120 can be folded at the same time, and the connecting rod 140 drives the sliding member 400 to move downward, so that the multiple supporting legs 200 are close to each other along the D1 direction and the D2 direction at the same time, thereby realizing the folding of the child carrier.

[0257] In this embodiment, since the first rotating arm 122 a does not restrict the rotating locking member 123 after being folded, when the child carrier is in the folded state, the rotating locking member 123 rotates from the rotating unlocking position to the rotating locking position under the elastic restoring force of the rotating restoring member 124 .

[0258] When the child carrier needs to be unfolded, the two first rotating arms 122a and the two second rotating arms 102b of one of the first armrests 110 (or the second armrests 120) are rotated so that the two first rotating arms 122a and the two second rotating arms 102b ... Fig.19 The folded position shown is Fig.17The two first rotating arms 122a and the two second rotating arms 102b of the second handrail frame 120 (or the first handrail frame 110) are driven by another connecting rod 140 connected to the sliding member 400 to rotate from the folded position to the unfolded position, thereby realizing that the two first handrail frames 110 and the two second handrail frames 120 of the handrail frame 100 of the child carrier are synchronously switched from the folded state to the unfolded state. Fig.19 The folded position shown is Fig.17 During the rotation process of the unfolded position shown in FIG. 1 , the ends of the two first rotating arms 122a push against the wedge-shaped surfaces 1239 of the corresponding rotating locking members 123, so that the two rotating locking members 123 rotate from the rotating locking position to the rotating unlocking position. Fig.18 In the unfolded position shown in FIG. 1 , the end of the first rotating arm 122a just leaves the wedge-shaped surface 1239 of the rotating locking member 123. At this time, the rotating locking member 123 is in the rotating unlocking position. Fig.18 Turn the lock to the indicated release position. Fig.17 In the rotation locking position shown, the end of the first rotation arm 122a is engaged with the engagement recess 1231 of the rotation locking member 123. In this way, the child carrier is unfolded.

[0259] According to a fourth embodiment of the present application, a support connection structure 1 and a child carrier equipped with the support connection structure are provided.

[0260] Figure 23 to Figure 28 1 is a schematic structural diagram of a support connection structure 1 provided according to a fourth embodiment of the present application. The support connection structure 1 includes two support connection components 10 and a linkage 20 drivingly connected to the two support connection components 10. Both support connection components 10 are rotating connection components 12, and the two rotating connection components 12 are respectively a first rotating component 12a and a second rotating component 12b.

[0261] Each rotating connection assembly 12 includes a rotating seat 121, at least one first rotating arm 122a, at least one second rotating arm 122b, at least one rotating locking member 123, and a rotating reset member 124 suitable for biasing the rotating locking member 123 to turn the rotating locking member 123 to the rotating locking position. In this embodiment, each rotating connection assembly 12 is configured with two first rotating arms 122a, two second rotating arms 122b and two rotating locking members 123. Among them, the two first rotating arms 122a act on different rotating locking members 123 respectively. Each rotating locking member 123 is provided with a snap-fitting recess 1231, and the facing ends of the two first rotating arms 122a form a snap-fitting protrusion 1221. When the rotating locking member 123 is located at the rotating locking position, the rotating connection assembly 12 is in a locked state, and the snap-fitting protrusions 1221 of the two first rotating arms 122a are respectively snap-fitted with the snap-fitting recesses 1231 of the corresponding rotating locking members 123, and the two first rotating arms 122a are restricted from rotating relative to the rotating seat 121. When the rotation locking member 123 is located at the rotation releasing position, the rotation connecting assembly 12 is in a releasing state, the two first rotation arms 122 a are rotatable relative to the rotation base 121 , and the two second rotation arms 122 b are rotatable relative to the rotation base 121 .

[0262] Furthermore, if Fig.23 As shown, the two rotation locking members 123 are respectively a first rotation locking member 123a located on the right side and a second rotation locking member 123b located on the left side. The two rotation locking members 123 are drivingly connected. Specifically, the two rotation locking members 123 are respectively provided with meshing teeth 1232. The two rotation locking members 123 mesh with each other through the meshing teeth 1232, so that when one of the rotation locking members 123 rotates, the other rotation locking member 123 is driven to rotate synchronously, so that the two rotation locking members 123 can be synchronously switched between the rotation locking position and the rotation release position. The rotation reset member 124 is, for example, a torsion spring. The number of the rotation reset member 124 is one, and the rotation reset member 124 abuts against one of the rotation locking members 123, for example, the first rotation locking member 123a.

[0263] The support connection structure 1 in this embodiment has at least the following differences compared with the support connection structure 1 in the third embodiment.

[0264] like Figures 23 to 24As shown, the first rotating assembly 12a is equipped with an operating member 125, while the second rotating assembly 12b is not equipped with an operating member 125. The operating member 125 is rotatably arranged on the rotating seat 121 of the first rotating assembly 12a, and is drivingly connected with the rotating locking member 123 to drive the rotating locking member 123 to switch between the rotating locking position and the rotating unlocking position. The operating member 125 is drivingly connected with one of the rotating locking members 123 of the first rotating assembly 12a to allow the rotating locking member 123 to rotate when the operating member 125 is operated, and the other rotating locking member 123 is driven to rotate synchronously through the meshing cooperation between the meshing teeth 1232 of the two rotating locking members 123, so as to realize that the two rotating locking members 123 are synchronously switched between the rotating locking position and the rotating unlocking position. It should be understood that in some other embodiments not shown, the rotating connection assembly 12 can also be equipped with only one rotating locking member 123, and this application is not limited to this.

[0265] like Fig.23 As shown, the two ends of the linkage 20 are respectively connected to the rotating locking members 123 of the two rotating connection components 12, so as to allow the operating member 125 to rotate, thereby driving the rotating locking member 123 of the first rotating component 12a to rotate, and driving the rotating locking member 123 of the second rotating component 12b to rotate through the linkage 20, so that the rotating locking members 123 of the two rotating connection components 12 rotate synchronously, thereby realizing the rotating locking members 123 of the two rotating connection components 12 synchronously switching between the rotation locking position and the rotation releasing position.

[0266] Fig.29The schematic diagram of the structure of the linkage 20 provided according to the fourth embodiment of the present application is shown. The linkage 20 includes a traction rope 21, a first stop end 22a and a second stop end 22b respectively arranged at both ends of the traction rope 21, and a sheath 23 sleeved outside the traction rope 21. The structures of the first stop end 22a and the second stop end 22b are basically the same. The first stop end 22a and the second stop end 22b are roughly cylindrical, and the two ends of the traction rope 21 are respectively connected to the side of the first stop end 22a and the side of the second stop end 22b. The sheath 23 is arranged outside the traction rope 21. At least a part of the traction rope 21, the first stop end 22a, and the second stop end 22b all extend out of the sheath 23. One end of the sheath 23 is provided with a first connecting end 24a suitable for the traction rope 21 to pass through, and the other end of the sheath 23 is provided with a second connecting end 24b suitable for the traction rope 21 to pass through. The first connection end 24a is limited to the rotating seat 121 of the first rotating assembly 12a, and the second connection end 24b is limited to the rotating seat 121 of the second rotating assembly 12b, so that the two ends of the sheath 23 are respectively fixedly connected to the rotating seats 121 of the two rotating connection assemblies 12. Such a configuration can, on the one hand, support the linkage 20, and on the other hand, fix the end of the sheath 23 to prevent the movement of the sheath 23 and affect the rotation of the rotating locking member 123.

[0267] Furthermore, if Fig.21 , Fig. 27 and Fig.28 As shown, the rotating seat 121 of the rotating connection assembly 12 is provided with a connecting frame 129, and the traction rope 21 of the linkage 20 can pass through the connecting frame 129. The connecting frame 129 is located in the receiving groove 1212 of the rotating seat 121. The connecting frame 129 is formed by tearing a part of the side wall 1213 of the rotating seat 121 and bending it inward (i.e., in the direction of the receiving groove). The connecting frame 129 and the rotating seat 121 are an integral component, thereby improving the connection strength between the connecting frame 129 and the rotating seat 121 and reducing the manufacturing cost. It can be understood that in other embodiments, the connecting frame 129 can also be a component fixed to the side wall 1213 of the rotating seat 121 by methods such as welding, riveting, bonding, etc., and this application is not limited to this. Continue to refer to Fig.23 and Fig. 27, the rotating seat 121 is configured with two connecting frames 129, which are a first connecting frame 129a arranged near the first rotating locking member 123a and a second connecting frame 129b arranged near the second rotating locking member 123b. Both connecting frames 129 are arranged near the side of the rotating locking member 123 away from the engaging recess 1231. The first connecting end 24a of the connecting member 20 is clamped to the second connecting frame 129b of the first rotating component 12a, and the second connecting end 24b of the connecting member 20 is clamped to the first connecting frame 129a of the second rotating component 12b. It can be understood that in some other embodiments, the first rotating component 12a can be configured with only one connecting frame 129, that is, only the second connecting frame 129b. The second rotating component 12b can also be configured with only one connecting frame 129, that is, only the first connecting frame 129a. Refer to Fig.23 and Fig. 27 In the present embodiment, the rotational reset member 124 is sleeved on the pivot axis of the first rotational locking member 123a, one end of the rotational reset member 124 abuts against the first rotational locking member 123a, and the other end of the rotational reset member 124 is clamped on the first connecting frame 129a. Of course, the rotational reset member 124 can also be sleeved on the pivot axis of the first rotational locking member 123b, one end of the rotational reset member 124 abuts against the second rotational locking member 123b, and the other end of the rotational reset member 124 is clamped on the second connecting frame 129b. It should be noted that the end of the connecting frame 129 of the present embodiment is open. In order to prevent the end of the rotational reset member 124 from slipping out of the end of the connecting frame 129, the connecting frames 129 on the two side walls 1213 of the rotating seat 121 can be arranged opposite to each other, so that the end of the rotational reset member 124 can be limited between the two connecting frames 129 (such as Fig. 27 and Fig.28 Of course, the ends of the rotational reset member 124 may not be limited by the two connecting frames 129, but a stopper structure (e.g., a hook-shaped stopper structure) may be provided at the ends of the connecting frames 129 to prevent the ends of the rotational reset member 124 from sliding out of the connecting frames 129. Fig.17 ), or one end of the rotation reset member 124 may abut against the first rotation locking member 123a, and the other end of the rotation reset member 124 may abut against a pin (not shown in the drawings) on the first rotation arm 122a.

[0268] Fig.30 FIG. 1 is a schematic diagram showing a structure of a first rotating locking member 123a of a rotating connection assembly 12 according to a fourth embodiment of the present application. Fig.23 , Fig.29, the first rotating locking members 123a of the two rotating connection components 12 are respectively provided with a snap-fitting groove 1233, and the first stop end 22a and the second stop end 22b are respectively engaged with the corresponding snap-fitting groove 1233. Specifically, the snap-fitting groove 1233 is provided on the side of the rotating locking member 123 away from the engagement recess 1231. The first rotating locking member 123a of the first rotating component 12a is provided with a snap-fitting groove 1233, and the first rotating locking member 123a of the second rotating component 12b is provided with a snap-fitting groove 1233. The first stop end 22a is engaged with the snap-fitting groove 1233 of the first rotating locking member 123a of the first rotating component 12a, and the second stop end 22b is engaged with the snap-fitting groove 1233 of the first rotating locking member 123a of the second rotating component 12b. Among them, the first stop end 22a and the second stop end 22b have the same structure. The engaging groove 1233 includes a first groove portion 12331 and a second groove portion 12332 suitable for the traction rope 21 to pass through, the first groove portion 12331 is connected to the second groove portion 12332, and the extension direction of the first groove portion 12331 is at an angle to the extension direction of the second groove portion 12332, and the first stop end 22a or the second stop end 22b is suitable for being engaged with the first groove portion 12331. In this embodiment, the second rotation locking member 123b of the two rotating connection components 12 is not provided with an engaging groove 1233. In some embodiments, the second rotation locking member 123b of the first rotating component 12a is provided with a retaining groove 1237, and both ends of the retaining groove 1237 are open ends to allow the traction rope 21 to pass through. When the first stop end 22a and the second stop end 22b are respectively engaged with the corresponding rotation locking member 123, the traction rope 21 passes through the engagement groove 1233 of the first rotation locking member 123a of the first rotating assembly 12a, the retaining groove 1237 of the second rotation locking member 123b of the first rotating assembly 12a, and the engagement groove 1233 of the first rotation locking member 123a of the second rotating assembly 12b in sequence. The operating member 125 is drivingly connected to the second rotation locking member 123b of the first rotating assembly 12a. The second rotating locking member 123b of the first rotating component 12a is driven to rotate through the operating member 125, and the rotating locking member 123a of the first rotating component 12a is driven to rotate through the meshing cooperation of the two rotating locking members 123 of the first rotating component 12a, and the first rotating locking member 123a of the second rotating component 12b is further driven to rotate through the connecting member 20, and then the second rotating locking member 123b of the second rotating component 12b is driven to rotate through the meshing cooperation of the two rotating locking members 123 of the second rotating component 12b, thereby making the rotating locking members 123 of the two rotating connecting components 12 rotate synchronously, so that the rotating locking members 123 of the two rotating connecting components 12 can be synchronously switched between the rotation locking position and the rotation releasing position.

[0269] The bracket connection structure 1 provided in this embodiment drives the two rotating connection components 12 to switch synchronously between the locking state and the unlocking state through the linkage 20, and has a simple structure and is easy to operate.

The child carrier of this embodiment differs from the child carriers provided in the first, second, and third embodiments described above in at least the following ways.

[0271] like Fig.31 As shown, the bed frame 1000 is equipped with the support connection assembly 10 of the support connection structure 1 in the fourth embodiment described above. The support connection assembly 10 includes a first rotating assembly 12a and a second rotating assembly 12b, wherein the first rotating assembly 12a serves as the first handrail frame 110, and the second rotating assembly 12b serves as the second handrail frame 120. Specifically, the two groups of first rotating arms 102a and the second rotating arms 102b of the first handrail frame 110 correspond to the two groups of rotating arms 122 of the first rotating assembly 12a (i.e., the first rotating arms 122a and the second rotating arms 122b), respectively. The connecting seat 101 of each first handrail frame 110 corresponds to the rotating seat 121 of the first rotating assembly 12a.

In this embodiment, the support connection structure 11 also includes an angle connector 130, a support leg 200 and a connection rod 140. The first handrail frame 110 and the second handrail frame 120 are connected to the angle connector 130, and the support leg 200 is connected to the angle connector 130. A slidable sliding member 400 is provided on the support leg 200, and the first handrail frame 120 and the second handrail frame 120 are respectively connected to the same sliding member 400 through the connection rod 140. The first handrail frame 110 and the second handrail frame 120 are connected by a driving member 20.

[0272] Compared to the third embodiment, when the child carrier of the present embodiment needs to be folded, it is only necessary to operate the operating member 125 of the first rotating assembly 12a disposed on the first armrest 110. Then, the two rotating locking members 123 of the first rotating assembly 12a and the two rotating locking members 123 of the second rotating assembly 12b can be synchronously turned from the rotation locking position to the rotation releasing position through the linkage member 20, thereby realizing the folding of the child carrier.

[0273] In the fourth embodiment, the unfolding process of the child carrier is substantially the same as that of the third embodiment, and will not be described in detail herein. According to a fifth embodiment of the present application, a support connection structure 1 and a child carrier equipped with the support connection structure 1 are provided.

The movable locking member 113 is plugged and matched with the slide slot 1111 through a connecting pin (not shown in the drawings), and the connecting pin is such as a rivet, a screw, a bolt, etc. Specifically, the movable locking member 113 is provided with a plurality of connecting holes 1134, and the connecting pin is penetrated in the slide slot 1111 and the connecting hole 1134 to realize the movable connection between the movable locking member 113 and the pivot seat 111. The pivot seat 111 and the movable locking member 113 are connected by the connecting pin, so that the connection between the two is more firm and reliable, and it is convenient to disassemble and assemble.

In other embodiments, the mobile connection component 11 can move between the mobile release position and the mobile lock position along an arc or other shaped line, which is not limited here.

[0288] According to a seventh embodiment of the present application, a support connection structure 1 and a child carrier equipped with the support connection structure 1 are provided.

[0289] Fig.41 A schematic structural diagram of a child carrier provided according to a seventh embodiment of the present application is shown. Figure 42 to Figure 44 The seventh embodiment of the present application provides a structural schematic diagram of a bracket connection assembly 10. This embodiment is different from the first embodiment, the second embodiment, the third embodiment, the fourth embodiment, the fifth embodiment and the sixth embodiment described above mainly in the following ways.

[0290] like Fig.41As shown, the child carrier includes a bed frame 1000, and the bed frame 1000 is equipped with a bracket connection structure 1. The bracket connection structure 1 includes at least one bracket connection component 10. In this embodiment, the bracket connection component 10 includes a first rotating component 12a and a second rotating component 12b, and the first rotating component 12a is drivingly connected to the second rotating component 12b through a connecting member 20. The first rotating component 12a serves as a first armrest frame 110, and the second rotating component 12b serves as a second armrest frame 120. In some other embodiments not shown, the bracket connection structure 1 may also include a rotating connection component 12, which is not limited in this application. For ease of description, one of the rotating connection components 12 (the second rotating component 12b) is taken as an example for explanation below.

[0291] like Fig.41 and Fig.42 As shown, the rotating connection assembly 12 includes a rotating seat 121, a first rotating arm 122a, a second rotating arm 122b and a rotating locking member 123. The rotating locking member 123 serves as a locking member of the bracket connecting assembly 10, and the rotating locking member 123 is provided with a clamping recess 1231. The first rotating arm 122a is pivotally connected to the rotating seat 121 through a pin 128a (for example, a rivet, a screw, a bolt, etc.), and the second rotating arm 122b is pivotally connected to the rotating seat 121 through a pin 128b. The first rotating arm 122a and the second rotating arm 122b both have an unfolded position and a folded position. When the rotating locking member 123 is located at the rotating unlocking position, the rotating connection assembly 12 is in an unlocking state, the first rotating arm 122a is rotatable relative to the rotating seat 121, and the second rotating arm 122b is rotatable relative to the rotating seat 121. When the rotation locking member 123 is located at the rotation locking position, the rotation connection assembly 12 is in a locked state, and the first rotation arm 122 a is restricted from rotating relative to the rotation seat 121 .

[0292] like Figure 43 to Figure 45As shown, the first rotating arm 122a includes a main body rod 1224, a clamping rod 1225 and a telescopic reset member 1226. The main body rod 1224 is pivotally connected to the rotating seat 121 through a pin 128a. One of the main body rod 1224 and the clamping rod 1225 is provided with an insertion cavity 12241, and the other of the main body rod 1224 and the clamping rod 1225 is inserted in and at least partially limited in the insertion cavity 12241, and the clamping rod 1225 can move relative to the main body rod 1224 and has an extended position and a retracted position. One end of the clamping rod 1225 away from the main body rod 1224 serves as a clamping protrusion 1221. In this embodiment, the main body rod 1224 is provided with a plugging cavity 12241, and one end of the clamping rod 1225 away from the clamping protrusion 1221 is inserted in the plugging cavity 12241. When the first rotating arm 122a is in the folded position, the engaging protrusion 1221 is separated from the engaging recess 1231, and the locking rod 1225 is in the extended position; when the first rotating arm 122a switches from the folded position to the extended position, the rotating locking member 123 pushes the engaging protrusion 1221, so that the locking rod 1225 moves from the extended position to the retracted position; when the first rotating arm 122a switches to the extended position, the engaging protrusion 1221 faces the engaging recess 1231, and the locking rod 1225 moves from the retracted position to the extended position, so that the engaging protrusion 1221 is engaged with the engaging recess 1231. When the locking rod 1225 is in the extended position, the total length of the first rotating arm 122a (i.e., the sum of the length of the main rod 1224 and the length of the portion of the locking rod 1225 extending from the main rod 1224) is the longest; when the locking rod 1225 is in the retracted position, the total length of the first rotating arm 122a is the shortest.

[0293] like Figure 44 to Figure 45 As shown, the clamping rod 1225 is provided with a guide groove 12252, the extension direction of the guide groove 12252 is parallel to the extension direction of the plug-in inner cavity 12241, and the pin shaft 128a is passed through and limited in the guide groove 12252. That is, the clamping rod 1225 and the main body rod 1224 are both pivotally connected to the rotating seat 121 through the pin shaft 128a, and the clamping rod 1225 is movably inserted in the plug-in inner cavity 12241. In this way, the clamping rod 1225 can not only rotate with the main body rod 1224 relative to the rotating seat 121, but also move relative to the main body rod 1224 between an extended position and a retracted position. In other embodiments not shown, the main rod 1224 may be pivotally connected to the rotating seat 121 via the pin 128a, the clamping rod 1225 may not be pivotally connected to the rotating seat 121, the clamping rod 1225 may be movably inserted into the insertion inner cavity 12241, and may be at least partially limited in the clamping rod 1225 by other limiting structures, and the present application does not impose any restrictions on this.

[0294] like Fig.45As shown, a plurality of convex ribs 12257 are formed on the outer side of the clamping rod 1225, and the convex ribs 12257 can slide along the insertion inner cavity 12241, and the convex ribs 12257 contact the inner wall of the main body rod 1224. Therefore, compared with the entire outer side of the clamping rod 1225 contacting the inner wall of the main body rod 1224, the friction between the clamping rod 1225 and the main body rod 1224 can be reduced by the convex ribs 12257 contacting the inner wall of the main body rod 1224 in this embodiment, and the sliding is smoother.

[0295] like Figure 45 to Figure 45 As shown, the end of the clamping rod 1225 away from the clamping protrusion 1221 is provided with a first plug-in end 12253a and a second plug-in end 12253b. The first plug-in end 12253a and the second plug-in end 12253b together form an introduction opening 12254 connected to the guide groove 12252, and the extension direction of the introduction opening 12254 is substantially parallel to the extension direction of the guide groove 12252. In this way, the pin 128a can be conveniently inserted into the guide groove 12252. At least one of the first plug-in end 12253a and the second plug-in end 12253b is provided with a limiting protrusion 12255. The clamping rod 1225 allows the pin shaft 128a to enter the guide groove 12252 through the introduction opening 12254, and abuts against the pin shaft 128a through the limiting protrusion 12255 to limit the separation of the guide groove 12252 and the pin shaft 128a, so that the clamping rod 1225 is at least partially limited in the insertion cavity 12241, thereby limiting the separation of the clamping rod 1225 and the main rod 1224. The pin shaft 128a can be conveniently engaged with the guide groove 12254 of the clamping rod 1225 through the cooperation of the introduction opening 12254 and the limiting protrusion 12255, so that the clamping rod 1225 can be quickly installed.

[0296] In this embodiment, both the first plug end 12253a and the second plug end 12253b are provided with a limiting protrusion 12255. The two limiting protrusions 12255 are rotationally symmetrically distributed, and the two limiting protrusions 12255 have the same structure. For ease of description, the structure of one of the limiting protrusions 12255 is taken as an example for description.

[0297] The limiting convex 12255 includes an introduction portion 12255a and a limiting hook portion 12255b, wherein the limiting hook portion 12255b is connected to the introduction portion 12255a and is closer to the guide groove 12252 than the introduction portion 12255a. The limiting hook portion 12255b is suitable for abutting against the pin 128a, thereby limiting the guide groove 12252 from separating from the pin 128a. The introduction portion 12255a gradually increases from an end away from the limiting hook portion 12255b to an end close to the limiting hook portion 12255b, and has an inclined surface. In this way, the pin 128a can be more smoothly engaged with the guide groove 12252 through the introduction opening 12254, thereby facilitating the assembly of the clamping rod 1225. Specifically, the process of the clamping rod 1225 clamping onto the pin 128a is as follows: the surface of the introduction portion 12255a of the limiting projection 12255 abuts against the pin 128a, so that the first plug end portion 12253a and the second plug end portion 12253b are elastically deformed, so that the clamping rod 1225 can move into the plug inner cavity 12241 along a direction parallel to the main rod 1224. When the clamping rod 1225 moves to make the limiting hook portion 12255b abut against the pin 128a, the first plug end portion 12253a, the second plug end portion 12253b and the two limiting hook portions 12255b are elastically deformed under the pressure of the pin 128a. The limiting hook 12255b of the clamping rod 1225 continues to move into the plugging inner cavity 12241 along a direction parallel to the main rod 1224, passing over the pin shaft 128a and being located at a side of the pin shaft 128a away from the engaging protrusion 1221. Thus, the pin shaft 128a is engaged with the guide groove 12252.

[0298] like Figure 43 to Figure 45 As shown, one end of the telescopic reset member 1226 abuts against the pin shaft 128a, and the other end of the telescopic reset member 1226 abuts against the clamping rod 1225. The telescopic reset member 1226 biases the clamping rod 1225 to move toward the extended position, so that when the clamping rod 1225 is not blocked by external force, the clamping rod 1225 is maintained in the extended position under the elastic restoring force of the telescopic reset member 1226, so that when the first rotating arm 122a rotates to the unfolded position, the clamping rod 1225 can automatically return to the extended position and engage with the engaging recess 1231 of the rotating locking member 123. The telescopic reset member 1226 includes, for example, a compression spring. The clamping rod 1225 is provided with a receiving cavity 12256, and the telescopic reset member 1226 is accommodated in the receiving cavity 12256. One end of the telescopic reset member 1226 abuts against the bottom wall of the receiving cavity 12256, and the other end of the telescopic reset member 1226 abuts against the pin shaft 128a.

[0299] In this embodiment, by providing a clamping rod 1225 that is movable relative to the main rod 1224, the first rotating arm 122a can be more smoothly engaged with the rotating locking member 123, that is, the first rotating arm 122a can be more smoothly switched from the folded position to the unfolded position. Specifically, in the process of switching the first rotating arm 122a from the folded position to the unfolded position, the engaging protrusion 1221 of the engaging rod 1225 is pushed by the rotating locking piece 123, and then the engaging rod 1225 retracts into the main rod 1224 (i.e. moves to the retracted position), so that the first rotating arm 122a can rotate smoothly relative to the rotating seat 121; when the first rotating arm 122a switches to the unfolded position, the engaging protrusion 1221 is opposite to the engaging recess 1231, and the engaging rod 1225 is not blocked by the rotating locking piece 123, and the engaging rod 1225 moves from the retracted position to the extended position, so that the engaging protrusion 1221 engages with the engaging recess 1231, thereby keeping the first rotating arm 122a in the unfolded position.

[0300] like Figure 41 to Figure 43 As shown, the support connection assembly 10 is also provided with an auxiliary reset member 105, one end of which is connected to the connection seat 101, and the other end of the auxiliary reset member 105 abuts against the first rotating arm 102a (i.e., the first rotating arm 122a), and the auxiliary reset member 105 biases the first rotating arm 102a to rotate toward the unfolded position. The auxiliary reset member 105 can provide an auxiliary force to rotate the first rotating arm 102a toward the unfolded position during the process of unfolding the bed frame 1000, that is, to make it easier for the first rotating arm 102a and the second rotating arm 102b (i.e., the second rotating arm 122b) to rotate toward the unfolded position. In this way, the bed frame 1000 can be unfolded more conveniently and labor-savingly. When the bed frame 1000 is in the folded state, the bed frame 1000 has a tendency to be unfolded under the elastic restoring force of the auxiliary restoring member 105, so the supporting legs 200 of the bed frame 1000 can be tied with ropes, straps, cable ties, etc. to completely restrict the bed frame 1000 in the folded state, so as to facilitate storage of the bed frame 1000. In this embodiment, the auxiliary restoring member 105 can be arranged on the first rotating arm 102a of the first handrail frame 110, or on the first rotating arm 102a of the second handrail frame 120, or on the first rotating arm 102a of the first handrail frame 110 and the first rotating arm 102a of the second handrail frame 120.

[0301] Combined with reference Fig.46, the auxiliary reset member 105 includes, for example, a torsion spring. The auxiliary reset member 105 includes two torsion spring main bodies 1053, two first ends 1051, and second ends 1052 respectively connected to the two torsion spring main bodies 1053. The first rotating arm 102a (i.e., the first rotating arm 122a) is pivotally connected to the connecting seat 101 through the pin 128a, and the two torsion spring main bodies 1053 are sleeved on the pin and are respectively located on both sides of the first rotating arm 102a. The two first ends 1051 are respectively abutted against the connecting seat 101 (i.e., the rotating seat 121). Specifically, abutment holes 1216 are respectively provided on the two side walls 1213 of the rotating seat 121, and the first ends 1051 are respectively inserted into the corresponding abutment holes 1216 and abut against the hole walls of the abutment holes 1216. The second end 1052 abuts against the first rotating arm 102a and is located between the first rotating arm 102a and the second rotating arm 102b.

[0302] In this embodiment, if Fig.42 and Fig.46 As shown, the second end portion 1052 is generally U-shaped. When installing the auxiliary reset member 105, it can be achieved in the following two ways:

[0303] Method 1: After the first rotating arm 102a is inserted under the second end 1052, the two torsion spring main bodies 1053 are installed on both sides of the first rotating arm 102a and sleeved on the pin shaft 128a. Finally, the two first end portions 1051 are respectively inserted into the corresponding abutment holes 1216 and abut against the hole walls of the abutment holes 1216.

[0304] Method 2: Insert the two first end portions 1051 into the corresponding abutment holes 1216 respectively and abut against the hole walls of the abutment holes 1216. After the first rotating arm 102a is inserted under the second end portion 1052, the two torsion spring main bodies 1053 are finally installed on both sides of the first rotating arm 102a and sleeved on the pin shaft 128a.

[0305] When the first rotating arm 102a is in the folded position, the auxiliary restoring member 105 is in an elastic energy storage state, and the elastic restoring force of the auxiliary restoring member 105 causes the first rotating arm 102a to slightly rotate toward the unfolded position or causes the first rotating arm 102a to have a tendency to rotate toward the unfolded position, thereby making the bed frame 1000 easier to unfold.

[0306] like Fig.41As shown, in this embodiment, the support connection structure 11 further includes an angle connector 130, a support leg 200 and a connecting rod 140. The first armrest frame 110 and the second armrest frame 120 are connected to the angle connector 130, and the support leg 200 is connected to the angle connector 130. A slidable sliding member 400 is provided on the support leg 200, and the first armrest frame 120 and the second armrest frame 120 are respectively connected to the same sliding member 400 through the connecting rod 140. The first armrest frame 110 and the second armrest frame 120 are driven and connected by the linkage 20.

[0307] Compared with the first to sixth embodiments, in the seventh embodiment, during the switching process of the child carrier from the folded state to the unfolded state, the elastic restoring force of the auxiliary restoring member 105 provides the first rotating arm 102a (i.e., the first rotating arm 122a) to rotate to the unfolded position, so that the child carrier (bed frame 1000) is easier to unfold. In addition, during the switching process of the bed frame 1000 from the folded state to the unfolded state, the locking rod 1225 of the first rotating arm 122a is pushed back by the rotating locking member 123. When the first rotating arm 122a rotates to the right position (i.e., rotates to the unfolded position), the locking rod 1225 extends out of the insertion cavity 12241 of the main rod 1224 and engages with the engaging recess 1231 of the rotating locking member 123.

[0308] In the seventh embodiment, the folding process of the child carrier (i.e., the process of switching from the open state to the folded state) can refer to the fourth embodiment, the fifth embodiment and the folding process, and will not be described in detail here.

[0309] Of course, the bracket connection assembly 10 in the above-mentioned embodiment 1, embodiment 2, embodiment 3, embodiment 4, embodiment 5 and embodiment 6 may also be provided with an auxiliary resetting member 105 to assist in unfolding the bed frame 1000, and this application does not impose any limitation on this.

[0310] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0311] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
