[0023] See also Figures 1 to 4 , shows a schematic diagram of a support connection structure 200 provided by an embodiment of the present invention. The support connection structure 200 at least includes a pivot seat 21, at least one pivot arm 22, and a locking member 24, and the pivot arm 22 and the locking member 24 are mounted on the pivot seat 21. The support connection structure 200 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 playpen, and other types of cribs), a baby stroller, etc., so as to allow the rods of the baby carrier equipped with the support connection structure 200 to be unfolded and folded, so as to switch between a use state and a folded state to meet the different usage requirements of users.

[0024] In some embodiments, in conjunction with reference Figures 1 to 3The bracket connection structure 200 can be configured with two pivot arms 22, and the first ends 221 of the two pivot arms 22 are pivotally connected to the pivot connection part 21a of the pivot seat 21 through two first pins 23, respectively, and the axis XX of each first pin 23 is also the pivot axis of the corresponding pivot arm 22. When the pivot arm 22 is installed on the pivot seat 21, the pivot axis YY of the pivot connection part 21a substantially coincides with the axis XX of the first pin 23. In some embodiments, the first ends 221 of the two pivot arms 22 are matched with the same locking member 24 located therebetween. In some embodiments, the geometric structure of the pivot seat 21 can be symmetrical with respect to the middle plane MM between the two first pins 23, and the middle plane MM is parallel to the axis XX of each first pin 23 and perpendicular to the center line of the two first pins 23. The first end 221 of each pivot arm 22 includes a first stop surface 220. In some embodiments, the first end 221 of each pivot arm 22 is formed by a plastic member sleeved on a rod-shaped member. In some other embodiments, each pivot arm 22 may be an integrally formed part.

[0025] The lock member 24 is mounted on the pivot seat 21 and can move in a direction parallel to the axis XX of the first pin shaft 23, so as to allow the lock member 24 to move axially to a locked position and an unlocked position. The lock member 24 includes a second stop surface 240 that cooperates with the first stop surfaces 220 of the two pivot arms 22. When the lock member 24 moves to the locked position, the first stop surface 220 of each pivot arm 22 can abut against the second stop surface 240 of the lock member 24, thereby limiting the rotation of the pivot arm 22 around the first pin shaft 23, so that the relative position of the pivot arm 22 and the pivot seat 21 remains fixed, that is, the lock member 24 locks the pivot arm 22 at a predetermined pivot position. When the lock member 24 moves to the unlocking position, the first stop surface 220 is separated from the second stop surface 240, and the lock member 24 does not interfere with the rotation of the pivot arm 22, that is, the lock member 24 releases the position lock of the pivot arm 22 at the predetermined pivot position, thereby allowing the pivot arm 22 to rotate to a suitable position around the first pin 23. Of course, in some other embodiments, the bracket connection structure 200 may include a pivot arm 22 and a lock member 24, and the rotation or stationary state of the pivot arm 22 relative to the pivot seat 21 is controlled by the axial movement position of the lock member 24.

[0026] The bracket connection structure provided in the above embodiment of the present invention can limit the rotation of the pivot arm 22 or allow the pivot arm 22 to rotate by changing the axial position of the locking member 24, thereby providing a bracket connection structure with a simple structure and easy state change.

[0027] See also Figure 3 and Figure 4In some embodiments, the pivot seat 21 includes a slideway 210 that is slidably matched with the lock member 24, and the extension direction of the slideway 210 is parallel to the axis XX of the first pin shaft 23. In some embodiments, the lock member 24 can be matched with the slideway 210 in a non-rotatable manner, that is, the circumferential rotation of the lock member 24 is limited by the slideway 210, so that it can be easily achieved that when the first stop surface 220 and the second stop surface 240 are abutted together, the pivot arm 22 will not push the lock member 24 to rotate. There are many ways to achieve that the lock member 24 and the slideway 210 can move relative to each other in the axial direction without relative rotation, for example, the cross section of the contact surface between the lock member 24 and the slideway 210 (the cross section perpendicular to the extension direction of the slideway) is a non-circular surface (for example, the cross section of the contact surface is a rectangular surface or a polygonal surface or a special-shaped surface), or the cross section of the contact surface between the lock member 24 and the slideway 210 is a circular surface with a radially protruding and radially recessed guide structure, etc. In some other embodiments, the rotation of the locking member 24 may not be restricted by the slideway 210 , as long as the locking member 24 can lock the pivot position of the pivot arm 22 when in the locked position.

[0028] In some embodiments, the lock member 24 can be switched between the locked position and the unlocked position by the user manually pushing the force-bearing end 24a of the lock member 24 to make the lock member 24 move axially parallel to the axis XX of the first pin shaft 23. In some embodiments, the bracket connection structure 200 may also include an elastic recovery structure 25, which is used to keep the lock member 24 in the locked position. When the lock member 24 is subjected to an external force, it can overcome the force of the elastic recovery structure 25 and move to the unlocked position. In this way, the lock member 24 is normally kept in the locked position, which is conducive to maintaining the stability of the lock member 24 in the locked position. When the lock member 24 needs to be changed to the unlocked position, an axial force can be applied to the lock member 24. There are many ways to implement the elastic recovery structure 25. For example, a spring is mounted on the lock member 24. When the lock member 24 is pushed by an external force and moves to the unlocked position, the spring is stretched or compressed. When the external force is removed, the spring can immediately drive the lock member 24 to automatically return to the locked position and can keep the lock member 24 in the locked position.

[0029] In some embodiments, the pivot seat 21 may also be provided with an axial limiting structure to prevent the locking member 24 from accidentally falling out of the slideway 210. The axial limiting structure may be provided in any suitable manner, and some implementations of the axial limiting mechanism are also shown below.

[0030] In addition, in some embodiments, in order to reduce the possibility of the lock member 24 being accidentally touched in the locked position and causing an unexpected axial movement to the unlocked position, when the lock member 24 is in the locked position, the force-bearing end 24a and the other end 24b opposite to the force-bearing end 24a of the lock member 24 may not protrude from the slideway 210. That is, when projected onto a plane parallel to the axis XX of the first pin 23, the force-bearing end 24a and the other end 24b opposite to the force-bearing end 24a are located between the two ends of the slideway 210 (including the two ends of the slideway 210). Of course, in some embodiments, only the force-bearing end 24a or the other end 24b opposite to the force-bearing end 24a may not protrude from the slideway 210. It should be noted that the situation where the above-mentioned end of the lock member 24 slightly protrudes from the slideway 210 also falls within the protection scope of the present invention. Of course, in some embodiments, in order to facilitate the application of external force to the locking member 24, when the locking member 24 is in the locked position, its force-bearing end 24a for receiving the external force may protrude from the slideway 210 (see Figure 4 ).

[0031] See below Figures 1 to 4 In some embodiments, the first end 221 of the pivot arm 22 includes a stop recess 2212, and the lock member 24 includes a stop protrusion 2412a. The surface of the stop recess 2212 is used to form a first stop surface 220, and the surface of the stop protrusion 2412a is used to form a second stop surface 240. By moving the lock member 24 to the locking position, when the stop recess 2212 and the stop protrusion 2412a are engaged, the first stop surface 220 and the second stop surface 240 are in contact, and the pivoting of the pivot arm 22 can be restricted. When the lock member 24 is moved to the unlocking position, the stop recess 2212 and the stop protrusion 2412a are staggered in the axial direction, and the lock member 24 does not restrict the pivoting of the pivot arm 22, and the pivot arm 22 can rotate around the axis XX of the first pin 23. Of course, in some other embodiments, the positions of the stopping recess and the stopping protrusion on the first end of the pivot arm 22 and the locking member 24 can be interchanged.

[0032] See also Figure 3 In some embodiments, the pivot seat 21 may further include arcuate walls 213 that are concentric with each first pin shaft 23. Taking one of the arcuate walls 213 as an example, the middle portion of the arcuate wall 213 includes an overlap portion 2131 that overlaps with the wall of the slideway 210, and the overlap portion 2131 is provided with a notch 2132. The first end 221 of the pivot arm 22 includes an arcuate portion 2211 that slidably cooperates with the inner wall surface 2130 of the arcuate wall 213 and a stopper recess 2212 in the middle portion of the arcuate portion 2211. Figure 1 and Figure 3When the lock member 24 is in the locked position, the stop convex portion 2412a of the lock member 24 is stuck in the notch 2132. At this time, the axial position of the lock member 24 is limited. The stop convex portion 2412a extends through the notch 2132 into the stop concave portion 2212 of the first end 221 of the pivot arm 22, thereby engaging with the stop concave portion 2212, so that the second stop surface 240 can abut against the first stop surface 220, thereby limiting the pivot arm 22 in the clockwise direction F1 and the counterclockwise direction F2 (see FIG. Figure 1 The above embodiment allows the stop convex portion 2412a to be engaged with the stop concave portion 2212 through the concave portion 2132 by providing structures such as the arc wall 213 and the concave portion 2132, which helps to reduce the size of the entire bracket connection structure in the axis XX direction while ensuring the structural strength of the pivot seat 21.

[0033] In some embodiments, the first anti-rotation surface 220 may be an inclined surface or a bent surface, and / or the second anti-rotation surface 240 may be an inclined surface or a bent surface, wherein the bent surface may be a right-angle bent surface or a multi-bent bent surface or any other suitable bent surface, as long as the rotation of the pivot arm 22 can be limited. It can be understood that in some embodiments, by setting appropriate shapes of the recess 2132 and the stop convex portion 2412a, the rotation of the locking member 24 can lock the pivot position of the pivot arm 22 in the locked position even if it is not limited by the slide 210.

[0034] See also Figure 3 In some embodiments, the locking member 24 may include a first slider portion 2411 and a second slider portion 2412 which are sequentially arranged in the sliding direction of the locking member 24 and respectively slideably cooperate with the slide 210. The first slider portion 2411 and the second slider portion 2412 may constitute a slider 241, and the slider 241 is, for example, an integrally formed part. Among them, the second slider portion 2412 is closer to the outside of the slide 210, and the first slider portion 2411 is located on the inner side of the second slider portion 2412. The first slider portion 2411 has an avoidance surface 2411a, and the avoidance surface 2411a can slideably cooperate with the wall surface of the overlapping portion 2131 and can move to the recess 2132. The stop protrusion 2412a is located on the second slider portion 2412. See also Figure 1 In some embodiments, the second slider portion 2412 may have a substantially rectangular profile, and two adjacent rectangular corners of the second slider 2412 respectively form stop convex portions 2412a to respectively cooperate with the stop concave portions 2212 at the first ends of the two pivot arms 22. At this time, the first stop surface 220 and the second stop surface 240 may be substantially right-angled bend surfaces.

[0035] When the lock member 24 is subjected to external force and overcomes the force of the elastic restoring structure 25 to move to the unlocking position, the second slider portion 2412 moves outward and drives the stop convex portion 2412a to move out of the recess 2132, the second stop surface 240 is separated from the first stop surface 220, and the avoidance surface 2411a of the first slider portion 2411 slides along the outer wall surface of the overlapping portion 2131 to the recess 2132 without interfering with the rotation of the pivot arm 22. At this time, the pivot arm 22 can rotate to a suitable position around the first pin 23. In the above embodiment, when the lock member 24 is in the locking position, the lock member 24 can have a larger contact area with the slideway 210 through the contact between the circumferential surface of the first slider portion 2411 (including the avoidance surface 2411a) and the partial circumferential surface of the second slider portion 2412 and the slideway 210. When the locking member 24 is in the unlocking position, at least the first slider portion 2411 can maintain contact with the slideway 210, so that it will not interfere with the rotation of the pivot arm 22. The first slider portion 2411 can also play a guiding role when the locking member 24 moves to the locking position.

[0036] See also Figure 1 In some embodiments, the edges of the arc-shaped wall 213 are also provided with angle limiting structures 2135, which can contact the first end 221 of the pivot arm 22 to limit the extreme positions of the pivot arm 22 in the clockwise direction F1 and the counterclockwise direction F2. Figure 1 That is, it shows that the pivot arm 22 is in one of the extreme positions, at which time the stop recess 2212 of the pivot arm 22 is aligned with the stop protrusion 2412a of the locking member 24, which can save the user's time in aligning the stop recess 2212 and the stop protrusion 2412a, and the user can easily lock the rotation of the pivot arm 22 by the locking member 24.

[0037] See also Figure 1 In some embodiments, when the lock member 24 is in the locked position, the two pivot arms 22 are opened to be substantially in the same straight line, which corresponds to the normal use state of the baby carrier. When the lock member 24 is in the unlocked position, the two pivot arms 22 can pivot around their respective first pins 23. When the two pivot arms 22 move to another extreme position, the two pivot arms 22 are folded relative to the pivot seat 21 to be parallel to each other, which corresponds to the folded state of the baby carrier.

[0038] See also Figure 3 and Figure 4In some embodiments, the locking member 24 may include a connecting column 242 and a button 243 and a slider 241 disposed at both ends of the connecting column 242. The end where the button 243 is located is, for example, the force-bearing end 24a, and the end where the slider 241 is located is, for example, the other end 24b opposite to the force-bearing end 24a. In some embodiments, the slider 241 may include a first slider portion 2411 and a second slider portion 2412. In some other embodiments, the slider 241 may also have other configurations. A limiting plate 2101 is disposed in the slide 210, and the limiting plate 2101 divides the slide 210 into a first slide portion 211 and a second slide portion 212 located on both sides of the limiting plate 2101. The limiting plate 2101 has a through hole 2102 for the connecting column 242 to pass through, the button 243 is suitable for slidingly cooperating with the first slide portion 211, and the slider 241 is suitable for slidingly cooperating with the second slide portion 212. The limiting plate 2101 can limit the axial movement position of the button 243 and the slider 241, and play a role in limiting the lock member 24 from falling off the slide 210, that is, the limiting plate 2101 forms an axial limiting structure to prevent the lock member 24 from falling off the slide 210. Of course, in some other embodiments, the axial limiting structure may include, for example, some steps formed at different positions of the slide 210, and these steps can respectively limit the movement position of the button 243 and the slider 241 to prevent the lock member 24 from falling off.

[0039] See also Figure 4 , the locking member 24 is in the locked position, and the elastic restoring structure 25 includes a spring installed in the first slide portion 211 and located between the limiting plate 2101 and the button 243. When the button 243 is pressed by an external force, in this embodiment, the locking member 24 moves along the locking position. Figure 4 The lock member 24 moves to the left in the direction of the arrow L, and moves to the unlocking position along the axial direction (basically consistent with the extension direction of the slideway 210), and the spring is compressed. Figure 4 The spring tends to drive the lock member 24 to move axially to the locked position when the button 243 moves rightward in the direction of the arrow R in the middle. In some other embodiments, the elastic recovery structure 25 may include a spring installed in the second slide portion 212 and located between the limit plate 2101 and the slider 241. For example, the two ends of the spring are respectively connected to the limit plate 2101 and the slider 241. When the button 243 is pressed by an external force, the lock member 24 moves to the unlocked position while the spring is stretched. When the external force is removed, the spring also tends to drive the lock member 24 to move axially to the locked position.

[0040] In some embodiments, the button 243 and the connecting column 242 can be integrally formed, for example, by injection molding. The slider 241 and the connecting column 242 can be connected by a fastener 26 (see Figure 4) connection, in some embodiments, the fastener 26 is, for example, a bolt, which passes through the through hole of the slider 241 and is screwed into the center hole of the connecting column 241.

[0041] See also Figure 3 and Figure 4 In some embodiments, the pivot seat 21 may further include a sleeve portion 214, which, for example, extends from the arc wall 213 in a direction away from the first end 221 of the pivot arm 22. The lock member 24 is provided with a hook 2413, for example, the hook 2413 is provided on the slider 241. The bracket connection structure 200 also includes a fixed arm 27, and the first end of the fixed arm 27 includes a bayonet 270. The first end of the fixed arm 27 can be sleeved in the sleeve portion 214. When the lock member 24 is in the locked position, the hook 2413 can extend into the sleeve portion 214 through the opening 2140 of the sleeve portion 214 and be engaged in the bayonet 270, so that the fixed arm 27 is connected to the pivot seat 21. When the lock member 24 is in the unlocked position, the hook 2413 at least withdraws from the bayonet 270 to allow the fixed arm 27 to be separated from the sleeve portion 214. In this way, the pivot position locking of the pivot arm 22 relative to the pivot seat 21 and the detachable connection of the fixed arm 27 and the pivot seat 21 are associated through the same locking member 24, providing a bracket connection structure 200 with a simple structure and easy folding and disassembly. In some embodiments, a limiting step is formed inside the sleeve portion 214, for example, and the limiting step can abut against the first end of the fixed arm 27 to limit the insertion depth of the fixed arm 27 in the sleeve portion 214; when the hook 2413 is engaged with the bayonet 270, the movement of the fixed arm 27 in the direction of being pulled out of the sleeve portion 214 can be limited.

[0042] In some embodiments, the hook 2413 includes a U-shaped plate 2413a and a pair of hook-shaped portions 2413b connected by the U-shaped plate 2413a, and the pair of hook-shaped portions 2413b are used to engage with the bayonet 270 at the same time. The second slider portion 2412 of the slider 241 may include a groove 2410 for partially accommodating the U-shaped plate 2413a, and the U-shaped plate 2413a may be detachably installed in the groove 2410 by the above-mentioned fastener 26, for example. The hook 2413 is detachably connected to the slider 241 as a consumable part, which is convenient for users to repair and replace. In some embodiments, the slider 241 may also include a spacer 2401 extending between the opposite side walls of the U-shaped plate 2413a, which is conducive to improving the structural strength of the hook 2413.

[0043] See below Figures 5 to 7 , shows the structure of a baby crib bed body 100 provided in some embodiments of the present invention, and the bed body 100 applies the bracket connection structure 200 provided in the above embodiment.

[0044] The bed body 100 may include an upper bed guard 10a and a lower bed guard 10b located below the upper bed guard 10a. The upper bed guard 10a and the lower bed guard 10b are both roughly rectangular in shape. The upper bed guard 10a and the lower bed guard 10b each include a pair of opposite first connecting rods 11 and a pair of opposite second connecting rods 12, and the adjacent first connecting rods 11 and second connecting rods 12 are respectively connected by corner connectors 13. The corner connectors 13 of the upper bed guard 10a and the corresponding corner connectors 13 of the lower bed guard 10b are connected by vertical connectors 14. In some embodiments, the corner connectors 13 and the vertical connectors 14 of the corresponding corners of the upper bed guard 10a and the lower bed guard 10b can be made into an integral part.

[0045] In some embodiments, each first link 11 includes a first rotating arm 111 and a second rotating arm 112, wherein the facing ends of the first rotating arm 111 and the second rotating arm 112 are respectively pivotally connected to the hinge seat, and the opposite ends of the first rotating arm 111 and the second rotating arm 112 are respectively pivotally connected to the corresponding corner connector 13. In this way, when the bed body 100 is folded, the hinge seat 151 of the upper bed guard 10a and the corresponding hinge seat 152 of the lower bed guard 10b are close to each other, so that the pair of second links 12 of the upper bed guard 10a are close to each other and the pair of second links 12 of the lower bed guard 10a are close to each other (see FIG. Figure 6 ) to allow the bed body 100 to be folded into a folded state (see Figure 7 ).

[0046] Depend on Figure 5 It can be seen that each first link 11 of the upper bed guard 10a adopts the structure of the bracket connection structure 200 of the above embodiment, that is, the first rotating arm 111 and the second rotating arm 112 of each first link 11 respectively serve as the pivot arm 22 of the bracket connection structure 200, and the hinge seat 151 corresponding to each first link 11 of the upper bed guard 10a respectively serves as the pivot seat 21 of the bracket connection structure 200. The hinge seat 152 corresponding to each first link 11 of the lower bed guard 10b can be a groove-shaped member with an open top, and the two ends of the groove-shaped member respectively extend out lugs 1521 for pivotal connection with the corresponding first rotating arm 111 and second rotating arm 112.

[0047] It can be understood that in some other embodiments, each first link 11 of the lower bed guard 10b can also adopt the structure of the above-mentioned bracket connection structure 200. In addition, in some other embodiments, one first link 11 of the upper bed guard 10a can adopt the structure of the above-mentioned bracket connection structure 200, and another first link 11 of the upper bed guard 10a does not adopt the structure of the above-mentioned bracket connection structure 200, and the first rotating arm 111 and the second rotating arm 112 of the other first link 11 can pivot relative to the corresponding hinge seat 151 of any suitable form without affecting the overall folding of the bed body 100.

[0048] It can be understood that in some other embodiments, each second connecting rod 12 of the upper bed guard 10a and the lower bed guard 10b can also be folded. For example, at least part of the second connecting rod 12 can adopt the structure of the above-mentioned bracket connection structure 200.

[0049] It should be noted that the first connecting rods 11 and the second connecting rods 12 of the structure of the above-mentioned bracket connecting structure 200 are adopted, wherein the hinge seat of the pivot seat 21 used as the bracket connecting structure 200 can be configured with the sleeve portion 214 and the hook 2413 as needed, or the sleeve portion 214 and the hook 2413 can be not configured as needed.

[0050] In some embodiments, see Figure 7 When the bed body 100 is in the folded state, the hinge seat 152 of the first link 11 of the lower bed guard 10b is located inside the corresponding hinge seat 151 of the upper bed guard 10a. By allowing the hinge seat 152 and the hinge seat 151 to overlap, it is helpful to reduce the overall height of the bed body 100 after folding.
