Referring to fig. 1 and 22, a child carrier 1000 provided in accordance with an embodiment of the present invention is shown. The child carrier 1000 comprises a child carrier 400 and a support device 300 provided according to an embodiment of the invention, the child carrier 400 being an attachment means for detachable mounting on the support device 300. The child carrier 400 has a folding joint 200, and the supporting device 300 has a connecting joint 100 provided according to an embodiment of the present invention, and the folding joint 200 is detachably connected with the connecting joint 100, so that the child carrier 400 is detachably connected with the supporting device 300. In the embodiment of the present invention, the child carrier 1000 is illustrated as a stroller, and the support means 300 is more specifically a frame of the stroller, and the child carrier 400 may be a foldable seat, a folding frame for use with an infant carrier, or the like. In alternative embodiments, the type of child carrier 1000 is not limited to a stroller, and may be, for example, a child bed frame or other product. Depending on the type of child carrier 1000, the type of support device 300 and child carrier 400 may vary accordingly. In addition, the application range of the connection joint 100 provided in the embodiment of the invention is not limited to the child carrier 1000, and the connection joint can be applied to any suitable product.

Referring to fig. 1, in some embodiments, the child carrier 1000 is substantially side-to-side symmetrical in structure. The support device 300 includes, for example, a rider 91, a front foot rest 92, a rear foot rest 95, a connection joint 100, and the like. The same side of the rider 91 and the front leg frame 92 are connected by a connecting joint 100, and the rider 91 is pivotally connected to the rear leg frame 95. More specifically, the connection joint 100 includes a first pivot seat 11 and a first mount 12, and the first pivot seat 11 and the first mount 12 are pivoted by a first pivot 101 (see fig. 3) to be rotatable relative to each other. In some embodiments, the first pivot seat 11 has a connecting cylinder 1101, and the rider 91 is sleeved with the connecting cylinder 1101 as a first rotating frame. The first mount 12 has a connection cylinder 1201, and the front foot stand 92 is sleeved with the connection cylinder 1201 as a second rotating frame.

It should be noted that, unless explicitly specified and limited otherwise, the terms of orientation such as "front", "rear", "left", "right", etc. in the embodiments of the present invention are based on the "front", "rear", "left", "right" orientation of the child seated in the child carrier, and the "front", "rear" direction is schematically shown by arrow H, P, and the "left", "right" direction is schematically shown by arrow L, R. These directional terms are used only to make the description of the embodiments of the present invention clearer and are not used to unduly limit the scope of the present invention.

Referring to fig. 1, in some embodiments, the child carrier 400 includes a front support 94, a rear support 93, a folding joint 200, and the like. Wherein the same side of the front support 94 and the rear support 93 are connected by a folding joint 200. More specifically, the folding joint 200 includes a second mounting seat 21, a second pivot seat 22, and a third pivot seat 23, where the second mounting seat 21, the second pivot seat 22, and the third pivot seat 23 are pivotally connected together for relative rotation. The second mounting seat 21 is configured to be detachably mounted on the first mounting seat 12 of the connection joint 100, so that the child carrier 400 is detachably mounted on the supporting device 300. In some embodiments, the second pivot mount 22 has a connecting barrel 2201, and the rear bracket 93 is sleeved with the connecting barrel 2201 as a third turret. The third pivot base 23 has a connection tube 2301, and the front bracket 94 is sleeved with the connection tube 2301 as a fourth turret.

Referring to fig. 2-4, in some embodiments, the connection joint 100 further includes a first locking member 13, the first locking member 13 being mounted between the first pivot mount 11 and the first mount 12. The first locking member 13 has a first locking position and a first unlocking position. In some embodiments, a chamber 10 is formed between the first pivot seat 11 and the first mount seat 12, and the first locking member 13 may be a first locking gear and may be axially movably disposed in the chamber 10. More specifically, referring to fig. 3, 4, 7 and 8 in combination, the first pivot 101 passes through the central hole 1100 of the first pivot seat 11, the central hole 1300 of the first locking member 13 and the central hole 1200 of the first mount seat 12. In some embodiments, the first pivot seat 11 has an annular gear 113 and the first mount 12 has an annular gear 123. Referring to fig. 3, when the first locking member 13 is in the first locking position, the first locking member 13 is simultaneously engaged with the ring gear 113 and the ring gear 123, i.e., the relative positions of the first pivot base 11 and the first mount base 12 can be locked. Referring to fig. 4, when the first locking member 13 is in the first unlocking position, the first locking member 13 moves into the first pivot seat 11 along the first pivot shaft 101 and is disengaged from the ring gear 123 of the first mounting seat 12, so that the first pivot seat 11 and the first mounting seat 12 can rotate relatively. In alternative embodiments, the first locking member 13 may have other embodiments, such as a bayonet-type structure.

Referring to fig. 4, 5 and 7, in some embodiments, a first resilient return member 15 may also be mounted in the chamber 10, the first resilient return member 15 being adapted to apply a force to the first locking member 13 to return the first locking member 13 to the first locking position. In some embodiments, the first resilient return member 15 is, for example, a spring, which is mounted between the first pivot seat 11 and the first locking member 13. In some alternative embodiments, the embodiment of the first elastic restoring member 15 varies accordingly, depending on the embodiment of the first locking member 13.

Referring to fig. 2-5, in some embodiments, the connection joint 100 further includes a first release 14, the first release 14 being mounted on the first mount 12 and operatively connected with the first lock 13.

The first lock release member 14 is for driving the first lock member 13 to move from the first lock position to the first lock release position. In some embodiments, the first release 14 is pivotally coupled to the first mount 12 by a first shaft 1211, the first shaft 1211 being perpendicular to the first pivot 101. The first lock release member 14 includes a first urging portion 141, and when the first lock release member 14 receives a driving force from, for example, a second driving member 211 (the second driving member 211 will be described later), the first lock release member 14 rotates about a first shaft 1211 while its first urging portion 141 urges the first lock member 13 directly or indirectly, so that the first lock member 13 moves from the first lock position to the first lock release position.

Referring to fig. 3 and 4, in some embodiments, the first lock release member 14 further includes a first abutment 142, the first abutment 142 is, for example, plate-shaped, and the first pushing portion 141 extends from the first abutment 142, for example. The function of the first abutment 142 will be described below.

Referring again to fig. 2 and 3, when the child carrier 1000 is in the deployed state, both the support device 300 and the child carrier 400 are in the deployed state, and the first locking member 13 is in the first locking position. As can be seen from the above, the first locking member 13 at the first locking position locks the first pivot seat 11 and the first mounting seat 12 so that the two cannot rotate relatively. Referring to fig. 4 and 5, when the child carrier 1000 is folded, the child carrier 400 may be folded first, and the second driving member 211 mounted on the second mounting seat 21 of the folding joint 200 moves during folding of the child carrier 400. The movement of the second driving member 211 indirectly drives the first unlocking member 14 of the connection joint 100 of the supporting device 300 to act, so that the first unlocking member 14 drives the first locking member 13 to move from the first locking position to the first unlocking position. As can be seen from the above, the first locking member 13 at the first locking position releases the first pivot seat 11 and the first mounting seat 12, allowing the two to rotate relatively, so that the supporting device 300 can be switched from the unfolded state shown in fig. 2 to the folded state shown in fig. 5.

The connection joint 100 provided by the embodiment of the invention can realize the switching from the unfolding state to the folding state on the basis of not disassembling the folding joint 200 of the child bearing device 400, and simplifies the folding operation of the connection joint 100, the supporting device 300 and the child bearing device 400. Of course, when the child carrier 400 is detached from the supporting apparatus 300, the user can directly operate the first locking member 14 to release the first locking member 13.

Referring to fig. 6-7, in some embodiments, the first pivot seat 11 is located on a first side 12a of the first mount 12 (which may also be referred to as an outer side of the first mount 12), the first release 14 is located on a second side 12b of the first mount 12 (which may also be referred to as an inner side of the first mount 12), and the second side 12b of the first mount 12 is configured to couple with the second mount 21. In some embodiments, when the child carrier 400 is mounted on the support apparatus 300, the first lock release 14 is covered by the second mounting seat 21, so that the first lock release 14 is prevented from being touched by mistake. More specifically, when the child carrier 400 is in the unfolded state and supports a child, the first lock release 14 is accidentally touched to cause the support device 300 to be accidentally folded.

Referring to fig. 6, an exemplary structure of the first mount 12 of the connection joint 100 and the second mount 21 of the folding joint 200 is shown. The second side 12b of the first mounting seat 12 is provided with a lock hole 120, and the second side 12b of the first mounting seat 12 has an outwardly protruding U-shaped clamping seat 121. The catch 121 is located below the lock hole 120, and an end surface of the catch 120 (also an end surface of the second side 12b of the first mount 12) is provided with a mounting recess 1210 (see fig. 7), and the first release lock 14 is located in the mounting recess 1210. The second mount 21 has a through hole 2108 and a card slot 210 on a side facing the first mount 12. Referring to fig. 3 and 4 in combination, the second mount 21 is mounted with a lock 2101, a lock release 2102 and a resilient return 2103. The lock 2101 is, for example, a lock pin. The resilient return 2103 drives the locking element 2101 out of the through hole 2108. The release member 2102 is operably connected to the locking member 2101 to drive the locking member 2101 to retract into the throughbore 2108.

With continued reference to fig. 3, 4 and 6, when the second mounting base 21 is mounted on the first mounting base 12, the clamping groove 210 of the second mounting base 21 is clamped with the clamping table 121 of the first mounting base 12, and the locking member 2101 is inserted into the locking hole 120. When the second mounting seat 21 needs to be disassembled, the release locking member 2102 is pressed, the locking member 2101 is driven by the release locking member 2102 to withdraw from the locking hole 120, and then the clamping groove 210 of the second mounting seat 21 is separated from the clamping table 121 of the first mounting seat 12.

Referring to fig. 3, 4 and 7 and 8, in some embodiments, the connection joint 100 further includes a first driving member 16, the first driving member 16 being sandwiched between the first lock release member 14 and the first locking member 13, the first lock release member 14 driving the first locking member 13 indirectly through the first driving member 16. In some embodiments, the first driving member 16 includes, for example, a pushing portion 161 and an abutment portion 162, the abutment portion 162 being, for example, disc-shaped, the pushing portion 161 including, for example, at least one leg portion extending from the abutment portion 161. The abutment portion 162 is located in the mounting recess 1210 and abuts the first pushing portion 141 of the first release member 14. The wall body of the first mounting seat 12 between the mounting recess 1210 and the chamber 10 is provided with at least one through hole 1208, and the pushing portion 161 abuts against the first locking member 13 after passing through the through hole 1208. The pushing portion 161 is slidably engaged with the through hole 1208 to guide the first driving member 16 to move in the axial direction of the first pivot 101. By arranging the first driving member 16 moving along the axial direction, the design difficulty of the first releasing member 14 can be reduced, and the first releasing member 14 can only push the first driving member 16 to move through the first pushing portion 141.

Referring to fig. 4, in some embodiments, the first lock release member 14 rotates about the first shaft 1211 when the second lock release member 17 (the second lock release member 17 will be described later) is driven by the second driving member 211, and the rotation of the first lock release member 14 drives the first driving member 16 to release the first lock member 13 to move the first lock member 13 from the first lock position to the first lock release position. It will be appreciated that, when the driving force applied to the first lock release member 14 by the second driving member 211 is removed, the first elastic restoring member 15 will drive the first lock member 13 to return from the first lock release position to the first lock release position, and accordingly, the first driving member 16 is driven to return by the first lock member 13, and the first lock release member 14 is driven to return by the first driving member 16. In some alternative embodiments, a torsion spring may be mounted on the first shaft 1211 for resetting the first locking release 14.

Referring again to fig. 3 and 4, in some embodiments, the connection joint 100 further includes the second release 17 described above, the second release 17 being mounted on the first mount 12 and operatively connected to the first release 14. As can be seen from the above description, in some embodiments, when the child-carrying device 400 is switched from the unfolded state to the folded state, the second driving member 211 moves along a direction perpendicular to the second pivot 201 (the second pivot 201 will be described below), and drives the first releasing member 14 to release the first locking member 13 through the second releasing member 17.

Referring to fig. 3, 4 and 7, 8, in some embodiments, the second release 17 is located in the mounting recess 1210 and the second release 17 is pivotally connected to the first mount 12 by a second shaft 1212. The second axis 1212 is parallel to the first axis 1211. The first end of the second lock release member 17 is clamped with the first lock release member 14, and the second end of the second lock release member 17 has a second abutting portion 172. In some embodiments, when the child carrier 400 is switched from the unfolded state to the folded state, the second driving member 211 moves and pushes the second abutment 172, so that the second locking member 17 rotates around the second shaft 1212. Rotation of the second lock release member 17 drives rotation of the first lock release member 14 about the first axis 1211, which in turn drives rotation of the first lock release member 14 to release the lock of the first lock member 13. Conversely, when the child carrier 400 is switched from the retracted state to the extended state, the second driving member 211 is reset and does not push the second abutment portion 172 of the second release member 17, as can be seen from the above, under the action of the first elastic reset member 15, the first locking member 13, the first driving member 16 and the first release member 14 will be reset, and the second release member 17 will be reset together with the first release member 14. In some alternative embodiments, a torsion spring may be mounted on the second shaft 1212 for resetting the second release 17.

Referring to fig. 3 and 6, in some embodiments, when the second release member 17 is not subjected to an external driving force, the second abutment 172 protrudes outward from the first mount 12. The second driving piece 211 can easily push the second abutting portion 172 when moving in the direction perpendicular to the second pivot 201. In some embodiments, the second abutment 172 has an inclined abutment surface 1721, and the second driving member 211 has an inclined pushing surface 2011 for abutting the inclined abutment surface 1721, and the cooperation of the inclined pushing surface 2011 and the inclined abutment surface 1721 helps the second locking member 17 to smoothly rotate.

Referring again to fig. 3, 4 and 7, 8, an exemplary manner of snap-fit engagement of the first and second release members 14, 17 is shown. The first release lock 14 has a first connection portion 143 fitted over the first shaft 1211, and the first connection portion 143 has a first tooth structure (tooth) 1431. The second lock release 17 has a second connection portion 171 sleeved on the second shaft 1212, and the second connection portion 171 has a second tooth structure (tooth) 1711. The first tooth-shaped structure 1431 of the first connection portion 143 is engaged with the second tooth-shaped structure 1711 of the second connection portion 171. The gear linkage mode of the first lock release piece 14 and the second lock release piece 17 can increase the pushing stroke of the first lock release piece 14 on one hand, and can reduce the pushing force of the second lock release piece 17 and increase the pushing stability of the second lock release piece 17 on the other hand, so that the stability and the effectiveness of the lock release process of the connecting joint 100 are improved, and the quick folding of the connecting joint 100 is realized. In some alternative embodiments, the first lock release member 14 and the second lock release member 17 may also be snapped or articulated by other suitable structures.

Referring to fig. 7 and 8, in some embodiments, the connection joint 100 may further include a mount 18, the mount 18 including, for example, two opposing side walls 182 and a plate 181 connected between the two side walls 182. The plate 181 and the two side walls 182 define a recess 180. Mounting holes 1821 and 1822 are provided in the two side walls 182. The first shaft 1211 is mounted in the mounting hole 1821 and the second shaft 1212 is mounted in the mounting hole 1822. The first and second connection portions 143 and 171 are accommodated in the recess 180. The fixing frame 18 is mounted in the mounting recess 1210, and the plate 181 partially closes the opening of the mounting recess 1210, preventing external parts from interfering with the engagement of the first and second connection portions 143 and 171.

Referring to fig. 9-12, there is shown a schematic construction of the child carrier 400 of fig. 1 and its folding joint 200, the child carrier 400 being for example a folding stand for use in connection with an infant carrier. The folding joint 200 includes the second locking member 24, the third locking member 25, the second mounting seat 21, the second pivoting seat 22, and the third pivoting seat 23. The second pivot 201 (see fig. 3) is inserted through the central hole 2100 of the second mounting base 21, the central hole 2200 of the second pivot base 22, and the central hole 2300 of the third pivot base 23, and the second mounting base 21, the second pivot base 22, and the third pivot base 23 are pivoted by the second pivot 201 to be relatively rotatable. The second pivot seat 22 is sandwiched between the second mount seat 21 and the third pivot seat 23. In some embodiments, the diameter of the central bore 2200 of the second pivot mount 22 may be substantially larger than the diameter of the second pivot shaft 201, the second pivot mount 22 being indirectly pivotally connected to the second pivot shaft 201 through the second mount 21 and/or the third pivot mount 23.

Referring to fig. 13 and 14, the second locking member 24 has a second locking position and a second unlocking position. In the second locking position, the second locking member 24 locks the second and third pivot seats 22, 23 against relative rotation, and the child carrier 400 remains in the deployed state. In the second lock release position, the second lock 24 releases the second pivot mount 22 and the third pivot mount 23, allowing relative rotation therebetween, allowing the child carrier 400 to switch to the stowed condition. In some embodiments, the second pivot base 22 is provided with a locking hole 220, the third pivot base 23 is provided with a through hole 230, and the second locking member 24 is slidably disposed in the through hole 230. The sliding direction of the second locking member 24 is, for example, parallel to the second pivot 201. When the locking hole 220 is opposite to the through hole 230, the first end 241 of the second locking member 24 is inserted into the locking hole 220, i.e., locks the second and third pivoting seats 22 and 23. Conversely, the first end 241 of the second locking member 24 is withdrawn from the locking aperture 220, i.e., the second and third pivot seats 22, 23 are unlocked.

Referring again to fig. 6 and 12, in some embodiments, a third release member 25 is mounted on the third pivot mount 23 and is operatively connected to the second lock member 24. The third lock release 25 is used to drive the second lock 24 from the second locking position to the second lock release position. In some embodiments, the third lock release 25 includes a pivot 251, the pivot 251 having a pivot 250, the pivot 2511 being mounted in the aperture 250. In some embodiments, the edge of the third pivot seat 23 has a notch 231, and the pivot 2511 is mounted in the notch 231 such that the third release latch 25 is pivotally connected to the third pivot seat 23 via the pivot 2511. Referring to fig. 14, the second end of the second locking member 24 is connected to the third unlocking member 25, and when the third unlocking member 25 receives an external pulling force, the third unlocking member 25 is rotated about the pivot 2511 while driving the second locking member 24 to move from the second locking position to the second unlocking position. In some embodiments, the third lock release member 25 has a plate shape, and when the second lock member 24 is in the second locked position, the third lock release member 25 is adapted to fit on a side of the third pivot seat 23 facing the third pivot seat 23 (may also be referred to as a side facing away from the second pivot seat 22) of the other folding joint 200.

Referring to fig. 11-14, in some embodiments, the second end of the second locking member 24 is sheet-like and has an elongated aperture 240 disposed therein. The inner side of the third release lock 25 facing the third pivot seat 23 is provided with a slot 252, and the second end of the second lock 24 is inserted into the slot 252. The walls of the slot 252 are provided with mounting holes 2520, the fasteners 253 are mounted in the mounting holes 2520, and the portions of the fasteners 253 located in the slot 252 pass through the elongated holes 240. When the third lock release member 25 is rotated about the pivot 2511 by an external pulling force, the second lock member 24 is moved from the second lock position to the second lock release position by the engagement of the fastener 253 with the elongated hole 240.

Referring to fig. 12, in some embodiments, the third release member 25 is further provided with a hole 255, and the pulling member 203 (see fig. 1) is connected to the third release member 25 through the hole 255. The left and right ends of the pulling member 203 may be connected with the third locking members 25 of the two folding joints 200 at the left and right sides of the child carrier 400, thereby simultaneously driving the second locking members 24 of the two folding joints 200 to be locked. In some embodiments, the pulling member 203 may be a webbing, a plastic strip, a rope, or the like.

Referring to fig. 12, in some embodiments, the folding joint 200 may further include a resilient return member 262, where the resilient return member 262 is configured to drive the third locking member 25 to return, thereby driving the second locking member 24 to insert into the locking hole 220. In some embodiments, an elongated counterbore 254 is provided on the third release lock 25, the elongated counterbore 254 having a step 2541. The side of the third pivot mount 23 facing away from the second pivot mount 22 may be mounted with a fastener 261, the fastener 261 passing through the elongated counterbore 254, and the fastener 261 having a head 2611. The fastener 261 is, for example, parallel to the second pivot 201. The elastic restoring member 262 may be a spring sleeved on the fastener 261, and two ends of the spring respectively abut against the head 2611 of the fastener 261 and the stepped portion 2541 of the elongated counterbore 254. When the third lock release member 25 is rotated about the pivot 2511 by an external pulling force, the elastic restoring member 262 is compressed. When the external pulling force applied to the third release member 25 is removed, the elastic restoring member 262 drives the third release member 25 to restore. In some embodiments, to facilitate the installation of the fastener 261, a boss 236 may be provided on a side of the third pivot seat 23 facing away from the second pivot seat 22, and the fastener 261 is secured into a hole (not numbered) in the boss 236. In some alternative embodiments, the resilient return member 262 may have other implementations, such as the resilient return member 262 being, for example, a torsion spring that is sleeved on the pivot 2511.

Referring to fig. 15, in some embodiments, the second mounting seat 21, the second pivot seat 22 and the third pivot seat 23 are linked through a planetary gear train, so that the child carrier 400 can be unfolded or folded more conveniently and in a labor-saving manner. More specifically, referring to fig. 11, the side of the third pivoting seat 23 facing the second pivoting seat 22 is provided with a sun gear 271. Referring to fig. 17, the side of the second mount 21 facing the second pivot seat 22 is provided with one or more planetary gears 272, and the second mount 21 acts as a planetary carrier. Referring to fig. 19, the side of the second pivoting seat 22 facing the third pivoting seat 23 is provided with an inner gear ring 273. The sun gear 271, the planet gears 272 and the ring gear 273 constitute a planetary gear train. Referring again to fig. 15, in the case that one of the second pivot mount 22 and the third pivot mount 23 is stressed (the stressed case includes the case that at least one of the second pivot mount 22 and the third pivot mount 23 is only subjected to gravity in the event that the folding joint 200 is unlocked), the second mount 21, the second pivot mount 22, and the third pivot mount 23 are pivoted about the second pivot shaft 201 by the planetary gear train, so that the child carrier 400 is folded quickly and with little effort.

It will be appreciated that when it is desired to deploy the child carrier 400, the folding joint 200 can be conveniently and quickly switched to the deployed state by applying force to one of the second and third pivot seats 22, 23 under the influence of the planetary gear train.

Referring to fig. 16-18, in some embodiments, the second driver 211 is slidably coupled with the second mount 21, and the second driver 211 is coupled with the second pivot 22 via the third driver 213. When the folding joint 200 is folded, the second mounting seat 21 and the second pivot seat 22 rotate relatively, and the third driving member 213 drives the second driving member 211 to slide relative to the second mounting seat 21 along a direction perpendicular to the second pivot 201. More specifically, the second mount 21 is provided with a chute 2130 on the outside thereof, and the second driver 211 is slidably disposed in the chute 2130. An elongated hole 2104 is provided in chute 2130. The third driving member 213 is, for example, a bent link, and is disposed between the second mounting base 21 and the second pivot base 22. The first end of the third drive member 213 is provided with a hole 2131 and the second drive member 211 is provided with a hole 2110, the pivot 2111 being provided through the hole 2110, the elongate hole 2104 and the hole 2131. That is, the first end of the third driving member 213 is pivotally connected to the second driving member 211 through a pivot 2111. The second end of the third driving member 213 is provided with a hole 2132, and the third driving member 213 is pivotally connected to the edge of the second pivot base 22 by a pivot (not shown) passing through the hole 2132.

Referring again to fig. 9, when the child carrier 400 is in the deployed state, the second driving member 211 is located at one end of the chute 2130. Referring to fig. 10, when the child carrier 400 is in the folded state, the second driving member 211 is located at the other end of the chute 2130. Referring to fig. 3 and 4 in combination, this change in position of the second driving member 211 drives the second lock release member 17 to rotate, thereby indirectly driving the first lock release member 14 to release the first lock member 13.

Referring again to fig. 12, in some embodiments, the second pivot base 22 may further be provided with an arcuately extending limit groove 22110, the limit groove 22110 being adapted to slidably engage the second locking member 24. More specifically, when the third release locking member 25 is pulled, the second locking member 24 is withdrawn from the locking hole 220, the second pivot seat 22 and the third pivot seat 23 may be first rotated slightly relative to each other, and then the external pulling force applied to the third release locking member 25 is released, and the third release locking member 25 is reset under the action of the elastic reset member 262 and drives the second locking member 24 to be inserted into the limiting groove 22110. The limit groove 22110 may also limit the pivoting angle ranges of the second pivot seat 22 and the third pivot seat 23. In some embodiments, the stop slot 22110 and the locking aperture 220 are in communication with each other via a slit, it being understood that the second locking member 24 cannot pass through the slit from one of the stop slot 22110 and the locking aperture 220 into the other.

Referring to fig. 20 and 21, there is shown yet another implementation of a connection joint 100 provided by an embodiment of the present invention. This embodiment differs from the connection joint 100 described above in that the first driving member 16 is omitted, the first pushing portion 141 of the first release member 14 includes, for example, at least one leg portion, and the first pushing portion 141 passes through the at least one through hole 1208 of the first mounting base 12 to directly abut against the first locking member 13. Thus being beneficial to reducing the number of parts and facilitating assembly.

Referring to fig. 22 and 23, another child carrier 1000 provided by an embodiment of the present invention is shown. The child carrier 1000 comprises a child carrier 400 and a support device 300 provided according to an embodiment of the invention. Referring to fig. 24 and 25, the supporting device 300 of the child carrier 1000 has the same structure as the supporting device 300, and the structure of the connecting joint 100 of the supporting device 300 can be described above, which is not repeated herein. The child carrier 1000 is different from the child carrier 1000 shown in fig. 1 in that the child seat 400 is exemplified by a foldable seat, the structure of the child carrier 400 and the folding joint 200 thereof is different from the previous embodiment, and the implementation of the second driving member 211 is also different.

Referring to fig. 24-26, a child seat 400 includes a seat tube 97, a back tube 98, a folding joint 200, and the like. Wherein the same side of the seat tube 97 and the back tube 98 are connected by a folding joint 200. More specifically, the folding joint 200 includes a second mount 21, a second pivot 22, a third pivot 23, a third lock 28, and a fourth release lock 29. The second mounting seat 21, the second pivot seat 22, the third pivot seat 23 and the fourth release lock 29 are pivoted together for relative rotation. The third locking member 28 is used for locking the second mounting seat 21 and the second pivot seat 22, and the fourth releasing member 29 is used for driving the third locking member 28 to release the lock.

In connection with the above, the second mounting seat 21 is configured to be detachably mounted on the first mounting seat 12 of the connection joint 100, so that the child carrier 400 is detachably mounted on the supporting device 300. Referring to fig. 27, in some embodiments, the second pivot mount 22 has a connecting barrel 2201, and the seat tube 97 is sleeved as a fifth turret with the connecting barrel 2201 of the second pivot mount 22. The third pivot seat 23 has a connection tube 2301, and the backrest pipe 98 is sleeved as a sixth turret with the connection tube 2301 of the third pivot seat 23.

Referring to fig. 28-30, an exemplary configuration of the child carrier 400 and its folding joint 200 of fig. 22 is shown. The second pivot 201 is inserted through the central hole 2100 of the second mounting base 21, the central hole 2200 of the second pivot base 22, the central hole 2300 of the third pivot base 23, and the central hole 2900 of the fourth release lock 29, and the second mounting base 21, the second pivot base 22, the third pivot base 23, and the fourth release lock 29 are pivoted by the second pivot 201 to be rotatable relative to each other. The second pivot seat 22 is sandwiched between the second mount seat 21 and the third pivot seat 23, and the third pivot seat 23 is sandwiched between the second pivot seat 22 and the fourth release lock 29.

As in the previous embodiment, the second mount 21 has a through hole 2108, a through hole 2109, and a card slot 210 on the side facing the first mount 12. Referring to fig. 28 and 29 in combination, the second mount 21 is mounted with a lock 2101, a lock release 2102 and a resilient return 2103. The resilient return 2103 drives the locking element 2101 out of the through hole 2108. The release member 2102 extends into the second mount 21 through the throughbore 2109 and is operatively connected to the locking member 2101 to drive the locking member 2101 to retract into the throughbore 2108. When the second mounting seat 21 is mounted on the first mounting seat 12, the clamping groove 210 of the second mounting seat 21 is clamped with the clamping table 121 of the first mounting seat 12, and the locking piece 2101 is inserted into the locking hole 120. When the second mounting seat 21 needs to be disassembled, the release locking member 2102 is pressed, the locking member 2101 is driven by the release locking member 2102 to withdraw from the locking hole 120, and then the clamping groove 210 of the second mounting seat 21 is separated from the clamping table 121 of the first mounting seat 12.

Referring to fig. 28, in some embodiments, a chamber 20 is formed between the second mount 21 and the second pivot 22, and the third locking member 28 is received in the chamber 20. The third locking member 28 may be a toothed wheel with a central aperture 2800 (see fig. 30) that fits over the second pivot 201. A third locking member 28 is axially movably disposed in the chamber 20 and has a third locking position and a third unlocking position. When the third locking member 28 is in the third locking position, the third locking member 28 is engaged with the second mounting seat 21 and the second pivot seat 22 at the same time, so that the relative positions of the second mounting seat 21 and the second pivot seat 22 can be locked. When the third locking member 28 is in the third unlocking position, the third locking member 28 moves into the second mounting seat 21 along the second pivot 201 and is disengaged from the second pivot seat 22, and the second mounting seat 21 and the second pivot seat 22 can rotate relatively. In some embodiments, a resilient return member 26 is also mounted in the chamber 20, the resilient return member 26 being adapted to drive the third locking member 28 to the third locking position. The elastic restoring member 26 is, for example, a spring, and is sandwiched between the second mount 21 and the third locking member 28.

Referring to fig. 28 and 29, in some embodiments, at least one through hole 2105 is provided in the wall between the card slot 210 and the chamber 20. The second driver 211 comprises, for example, at least one finger, which is integrally formed with or attached to the third locking member 28. At least one finger as the second driving piece 211 is slidably fitted with at least one through hole 2105 so that the second driving piece 211 is relatively slidably connected with the second mounting seat 21. It will be appreciated that the sliding direction of the second driving member 211 is parallel to the second pivot 201. With the switching of the third locking member 28 between the third locking position and the third unlocking position, the second driving member 211 expands and contracts with respect to the through hole 2105.

Referring to fig. 24, when the third locking member 28 is in the third locking position, the second driving member 211 does not protrude with respect to the through hole 2105, the second driving member 211 does not act on the first locking member 14 and the second locking member 17 of the connection joint 100, and the first locking member 13 is in the first locking position. Referring to fig. 25, when the third locking member 28 is at the third unlocking position, the second driving member 211 protrudes with respect to the through hole 2105, and the finger as the second driving member 211 directly pushes the first abutting portion 142 of the first unlocking member 14, so that the first unlocking member 14 is rotated about the first axis 1211 while directly or indirectly (without passing or by the first driving member 16) driving the first locking member 13 to move from the first locking position to the first unlocking position.

Referring to fig. 29 and 30, the third locking member 28 further comprises at least one finger 281, and at least one through hole 2107 is provided in the wall between the clamping groove 210 and the cavity 20, and the finger 281 is slidably engaged with the through hole 2107. The finger 281 and the finger as the second driving piece 211 are uniformly arranged in the circumferential direction of the third locking piece 28 to guide the axial movement of the second driving piece 211 together. Referring to fig. 25, as the second driving member 211, the finger is far from the first shaft 1211, and the finger 281 is near to the first shaft 1211. As can be seen from the above, the axial movement of the second driving member 211 pushes the first abutment 142 of the first locking member 14, so that the first locking member 14 rotates around the first shaft 1211, thereby locking the first locking member 13. Referring to fig. 7 and 25, in some embodiments, the first abutting portion 142 has a plate shape, and the first abutting portion 142 has a relief portion 1420, and the relief portion 1420 corresponds to the finger 281. The relief 1420 provides a space for the finger 281 to move, preventing the finger 281 from interfering with the normal release rotation of the first release member 14.

Referring to fig. 28-30, in some embodiments, a first movable plate 221 is also mounted in the chamber 20. The central hole 2210 of the first movable plate 221 is sleeved on the second pivot 201, and the first movable plate 221 is located between the third locking member 28 and the second pivot 22. At least one abutment post 222 is provided on the first movable piece 221, and the abutment post 222 extends in a direction away from the third locking piece 28. The second pivot seat 22 has at least one through hole 2203, and the abutment post 222 is slidably engaged with the through hole 2203.

Referring to fig. 28 to 30, in some embodiments, a chamber 30 is formed between the third pivot seat 23 and the fourth release latch 29. The chamber 30 is provided with a second movable plate 235, and a center hole 2350 of the second movable plate 235 is sleeved on the second pivot 201. The second movable piece 235 has at least one push post 2351, and the third pivoting seat 23 has at least one through hole 2303, and the at least one push post 2351 is slidably engaged with the at least one through hole 2303. The at least one pushing post 2351 is configured to push the at least one abutment post 222, so that the first movable plate 221 pushes the third locking member 28 to move from the third locking position to the third unlocking position. In some embodiments, a resilient return member 232 may also be provided in the chamber 30, the resilient return member 232 being adapted to drive the second movable plate 235 in a direction away from the first movable plate 221. The elastic restoring member 232 is, for example, a spring, and is sandwiched between the second movable piece 235 and the third pivot seat 23.

Referring to fig. 29 and 30, in some embodiments, the fourth locking member 29 rotates relative to the third pivot seat 23 to drive the second movable plate 235 to move axially, so that the pushing post 2351 of the second movable plate 235 pushes the abutment post 222 of the first movable plate 221. In some embodiments, the fourth release latch 29 is provided with at least one first end tooth 291 and the second movable tab 235 is provided with at least one second end tooth 2352. During the rotation of the fourth lock release member 29 relative to the third pivot seat 23, when the protrusion of the first end face tooth 291 abuts against the protrusion of the second end face tooth 2352, the second movable plate 235 is caused to move axially, and the pushing post 2351 of the second movable plate 235 pushes the abutment post 22 of the first movable plate 221, so that the first movable plate 21 moves, and the third lock member 28 is driven to move from the third locking position to the third lock release position. When the projections of the first end face teeth 291 and the projections of the second end face teeth 2352 are offset, the second movable piece 235 will move away from the first movable piece 231 to be reset by the elastic reset piece 232, and the second end face teeth 2352 and the first end face teeth 291 are in concave-convex engagement.

With continued reference to fig. 29 and 30, in some embodiments, the third pivot member 23 and the fourth release member 29 are provided with a rotation limiting mechanism to limit the range of relative rotation therebetween. For example, an arc-shaped groove 2305 may be provided on the third pivoting member 23, and an arc-shaped projection 295 may be provided on the fourth releasing member 29, the arc-shaped projection 295 being located in the arc-shaped groove 2305. The two ends of the arc-shaped protruding block 295 selectively abut against the two ends of the arc-shaped groove 2305, so as to limit the relative rotation range of the third pivot member 23 and the fourth locking member 29. In some embodiments, the positions of arcuate slot 2305 and arcuate tab 295 on third pivot 23 and fourth release latch 29 may be interchanged.

With continued reference to fig. 29 and 30, in some embodiments, the fourth release member 29 may also be provided with a hole 292, and the pull member 204 (see fig. 22) may be coupled to the fourth release member 29 through the hole 292. The pulling member 204 is pulled to rotate the fourth release member 29 relative to the third pivot base 23. The left and right ends of the pulling member 204 may be connected with the fourth locking members 29 of the two folding joints 200 at the left and right sides of the child carrier 400, thereby simultaneously driving the third locking members 28 of the two folding joints 200 to be locked. In some embodiments, the pull 204 may be a webbing, a plastic strip, a rope, or the like.

The folding operation of the child carrier 1000 will be briefly described with reference to fig. 27 and 28. When the child carrier 1000 needs to be folded, the back tube 98 is pushed forward and downward, and at this time, the first end face teeth 291 and the second end face teeth 2352 are in concave-convex fit, and the fourth lock release member 29 rotates together with the third pivot base 23. When the back tube 98 is retracted into place, the push post 2351 of the second movable plate 235 is aligned with the abutment post 222 of the first movable plate 221. And then applies a pulling force to the pulling member 204 to rotate the fourth release member 29 with respect to the third pivot base 23. During the process of abutting the protrusion of the first end face tooth 291 and the protrusion of the second end face tooth 2352, the second movable piece 235 moves in the axial direction, and the push post 2351 thereof pushes the abutment post 222 of the first movable piece 221, and the first movable piece 221 moves in the axial direction. The axial movement of the first movable plate 221 drives the third locking member 28 to move to the third unlocking position, and the second pivot seat 22 and the second mounting seat 21 can also rotate relatively, so that the child carrier 400 can be further folded. In addition, when the third locking member 28 moves to the third unlocking position, the second driving member 211 on the third locking member 28 directly pushes the first unlocking member 14. Referring to fig. 25, in combination with the above, the first locking member 14 is pushed by the second driving member 211 and then rotates about the first shaft 1211, so as to directly or indirectly drive the first locking member 13 to move to the first locking position. At this time, the supporting device 300 can be folded.

When the supporting device 300 is folded in place, the pulling force applied by the pulling member 204 is released, the second movable piece 235 is reset, the first movable piece 221 and the third locking piece 28 are reset under the action of the elastic reset piece 232 and the elastic reset piece 26, so that the first end face tooth 291 and the second end face tooth 2352 are in concave-convex fit, and the third locking piece 28 moves to the third locking position. The third locking member 28 drives the second driving member 211 to retract into the through hole 2105 without pushing the first releasing member 14. The first locking member 13 is reset to the first locking position by the first elastic reset member 15, and the first locking member 13 drives the first releasing member 14 to reset.

When the child carrier 1000 is in the retracted state, a pulling force is applied to the pulling member 204 to drive the third locking member 28 and the first locking member 13 to respectively move to the respective unlocking positions, so that the supporting device 300 and the child carrier 400 can be conveniently and again unfolded, thereby unfolding the child carrier 1000.

In summary, in the supporting device 300 according to the embodiment of the invention, when the connecting joint 100 is configured with the first releasing member 14 and the second releasing member 17, the connecting joint can be detachably connected with the folding joint 200 of the different types of child-carrying devices 400. In the case that the child carrier 400 is not detached from the supporting device 300, the first locking member 13 of the connection joint 100 is indirectly released by the second driving member 211 of the folding joint 200 during the folding process of the child carrier 400, so that the supporting device 300 can be folded as well.
