Thus, the unlocking operation between the first and second connectors is very effortless.

Description

Technical Field

[0001] This invention relates to the field of children's products, and more particularly to a connecting structure and a scooter equipped with the connecting structure. Background Technology

[0002] Children's products, such as scooters, strollers, cribs, and high chairs, are generally designed to switch between multiple states due to their characteristics. For example, they can be switched between an unfolded and folded state. When needed, they are locked in the unfolded state; when not in use, they are unlocked and folded to reduce space occupation and facilitate carrying and storage. Correspondingly, the two related components of these children's products are generally connected in a way that allows relative rotation and / or movement. In the unfolded state, the two components are locked and cannot rotate or / or move relative to each other; they can only rotate or / or move relative to each other after being unlocked. In other words, the change of position is achieved by switching between locking and unlocking the two related components.

[0003] Some children's products require adjusting the relative positions of two related components during use, such as adjusting the relative tilt angle of the seat back or the relative height of the high chair seat and the support. These adjustments are achieved by switching between locking and unlocking the two related components.

[0004] The two components use different connection methods, and their locking and unlocking operations are also different. Currently, the unlocking operation of children's products on the market is relatively difficult, making it inconvenient for unlocking. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a connection structure and a scooter, stroller, or crib equipped with the connection structure, which makes the unlocking operation very effortless.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A connection structure includes a first connector and a second connector that are rotatably and / or movably connected relative to each other, a first locking member and a second locking member that cooperate to restrict the relative rotation and / or movement of the first connector and the second connector, a pulley, and a flexible cable. The first locking member is connected to the first connector and is movable relative to the first connector, or the first locking member is connected to the first connector and the second connector and is movable relative to the first connector and the second connector. The second locking member is disposed on the second connector. The pulley is connected to the first locking member and is movable together with the first locking member, and the pulley is also rotatably rotatable relative to the first locking member about its central axis. The flexible cable passes over the pulley. When one end of the flexible cable is not moving, pulling the other end of the flexible cable causes the pulley to rotate about its central axis and move together with the first locking member, thereby disengaging the first locking member from the second locking member, allowing the first connector and the second connector to rotate and / or move relative to each other.

[0008] A first elastic reset member capable of driving the first locking member to reset is provided between the first locking member and the first connecting member or between the first locking member and the second connecting member.

[0009] One end of the flexible cable is connected to the first connector or the second connector.

[0010] The first locking element includes a locking seat and a mating element disposed on the locking seat. The locking seat is connected to the first connecting element and is movable relative to the first connecting element, or the locking seat is connected to the first connecting element and the second connecting element and is movable relative to the first connecting element and the second connecting element. The pulley is rotatably connected to the locking seat about its central axis. When the mating element is engaged with the second locking element, it can restrict the relative rotation and / or movement of the first connecting element and the second connecting element.

[0011] A children's product, including the above-mentioned connecting structure.

[0012] A scooter includes the aforementioned connecting structure. A first connector of the connecting structure is configured as the front frame of the scooter, and a second connector of the connecting structure is configured as the footboard of the scooter. The front side of the footboard is pivotally connected to the front frame, a first locking member is movably connected to the front frame, and one end of the flexible cable is connected to the front frame.

[0013] The scooter also includes a rider whose lower end is movable relative to the front frame and connected to it. The other end of the flexible cable is connected to an actuating element, which is movably connected to the front frame. When the rider moves downward relative to the front frame, it can activate the actuating element to pull the other end of the flexible cable.

[0014] The scooter also includes a linkage device connected to the front frame, which can be driven by the rider moving downwards to move the actuator downwards.

[0015] A stroller including the aforementioned connecting structure.

[0016] A first pivot seat is fixedly connected to one side of the first connector, and a second pivot seat is fixedly connected to one side of the second connector. The first pivot seat and the second pivot seat are pivotally connected. The first locking member is coaxially pivotally connected to the first pivot seat and the second pivot seat, and the first locking member is movable relative to the first pivot seat and the second pivot seat. The second locking member is disposed on the second pivot seat.

[0017] An operating mechanism is provided on the upper side of the first connector. One end of the flexible cable is connected to the first connector, and the other end passes around the pulley and is connected to the operating mechanism.

[0018] The stroller also includes a base support extending forward and backward, with the lower side of the first connector pivotally connected to the upper side of the second connector, and the lower side of the second connector pivotally connected to the front side of the base support, and the first connector, the second connector, and the base support forming an overall ∠ shape; or, the stroller also includes a front support and a rear support, with the lower side of the first connector pivotally connected to the upper side of the second connector, and of the three components—the rear side of the front support, the lower side of the second connector, and the front side of the rear support—two are pivotally connected, and the third is pivotally connected to one of the aforementioned two components, or the three components are coaxially pivotally connected.

[0019] A crib includes the aforementioned connecting structure.

[0020] The crib also includes multiple spaced side supports and a bottom bracket connected to the lower side of the multiple side supports. An armrest is connected to the upper side of each adjacent side support. The first connector and the second connector of the connection structure are configured as the two armrest tubes of the armrest.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. Because the connection structure of the present invention adopts the above design, the pulley can also rotate relative to the first locking member when pulling the first locking member to move, thereby forming a movable pulley structure. In this way, only half the force is needed to pull the first locking member to disengage from the second locking member and unlock the lock between the first connecting member and the second connecting member. Therefore, the unlocking operation of the connection structure of the present invention is very labor-saving. Thus, the unlocking operation between the front frame and the pedal of the scooter with the connection structure is very labor-saving, that is, the folding operation of the scooter of the present invention is very labor-saving. The unlocking operation between the first connecting member and the second connecting member of the stroller with the connection structure is also very labor-saving, and the unlocking operation of the two armrests of the crib with the connection structure is also very labor-saving.

[0023] 2. Because the scooter of the present invention adopts the above-described structure, the scooter can be folded by simply moving the rider down and operating the connecting structure. Therefore, the folding operation of the scooter of the present invention is even simpler. Because the stroller of the present invention adopts the above-described structure, the flexible rope can be pulled by simply operating the operating mechanism on the upper side of the first connecting member to release the lock between the first connecting member and the second connecting member. Therefore, the operation is also very simple. Attached Figure Description

[0052] like Figures 1 to 4As shown, the connection structure of the present invention includes a first connecting member 1 and a second connecting member 2 that are rotatably and / or movablely connected, a first locking member 3 and a second locking member 4 that cooperate with each other to restrict the relative rotation and / or movement of the first connecting member 1 and the second connecting member 2, a pulley 5, and a flexible cable 6. The first locking member 3 is connected to the first connecting member 1 and can move relative to the first connecting member 1, or the first locking member 3 is connected to the first connecting member 1 and the second connecting member 2 and can move relative to the first connecting member 1 and the second connecting member 2. The second locking member 4 is disposed on the second connecting member 2. The pulley 5 is rotatably connected to the first locking member 3 about its central axis, and the flexible cable 6 passes around the pulley 5. When one end of the flexible cable 6 is not moving, pulling the other end of the flexible cable 6 causes the pulley 5 to rotate about its central axis relative to the first locking member 3 and move together with the first locking member 3, so that the first locking member 3 disengages from the second locking member 4, and the first connecting member 1 and the second connecting member 2 can rotate and / or move relative to each other.

[0053] The first locking member 3 is connected to the first connecting member 1 and can move relative to the first connecting member 1. That is to say, the first locking member 3 is only connected to the first connecting member 1 and the first locking member 3 can move relative to the first connecting member 1. The first locking member 3 is connected to the first connecting member 1 and the second connecting member 2 and can move relative to the first connecting member 1 and the second connecting member 2. That is to say, the first locking member 3 is connected together with the first connecting member 1 and the second connecting member 2, and when the first locking member 3 moves, it moves relative to the first connecting member 1 and also moves relative to the second connecting member 2 at the same time.

[0054] The pulley 5 rotates about its central axis, that is, the pulley 5 rotates about its own central axis.

[0055] When the first locking member 3 and the second locking member 4 are engaged, the first connecting member 1 and the second connecting member 2 cannot rotate or / and move relative to each other, and the first connecting member 1 and the second connecting member 2 are in a relatively locked state; pulling the flexible rope 6 pulls the first locking member 3 through the pulley 5, causing the first locking member 3 to disengage from the second locking member 4, thereby unlocking the relative lock between the first connecting member 1 and the second connecting member 2, so that the first connecting member 1 and the second connecting member 2 can rotate or / and move relative to each other.

[0056] Because the connecting mechanism is configured in this way, after pulling the flexible cable 6, the pulley 5 can not only move relative to the first connecting member 1 together with the first locking member 3, but also rotate relative to the first locking member 3 around its own central axis. Thus, the pulley 5 forms a movable pulley structure relative to the first locking member 3. In this way, pulling the other end of the flexible cable 6 drives the pulley 5 and then pulls the first connecting member 1 to move, which saves half the force compared to pulling the first connecting member 1 directly through the flexible cable 6 in the conventional way. Therefore, the unlocking operation of the first connecting member 1 and the second connecting member 2 of the connecting structure of the present invention is very labor-saving.

[0057] In this embodiment, preferably, a first elastic reset member 30 is provided between the first locking member 3 and the first connecting member 1 or between the first locking member 3 and the second connecting member 2, which can drive the first locking member 3 to reset. Under the action of the first elastic reset member 30, the first locking member 3 moves toward the second locking member 4, and when the first locking member 3 and the second locking member 4 are aligned, the first locking member 3 automatically engages with the second locking member 4.

[0058] The flexible cable 6 can be configured as a rope, steel cable, chain, etc.

[0059] The first locking member 3 includes a locking seat 31 and a mating member 32 disposed on the locking seat 31. The locking seat 31 is connected to the first connecting member 1 and can move relative to the first connecting member 1, or the locking seat is connected to the first connecting member 1 and the second connecting member 2 and can move relative to the first connecting member 1 and the second connecting member 2. The pulley 5 is rotatably connected to the locking seat 31 about its central axis. When the mating member 32 is engaged with the second locking member 4, it can restrict the relative rotation and / or movement of the first connecting member 1 and the second connecting member 2, so that the first connecting member 1 and the second connecting member 2 are in a relatively locked state.

[0060] The mating part 32 can be integrally formed with the locking seat 31, or it can be a separate component connected to the locking seat 31.

[0061] In one embodiment, one end of the flexible cable 6 is connected to the first connecting member 1. When the other end of the flexible cable 6 is pulled, the first locking member 3 moves away from the second connecting member 2 and disengages from the second locking member 4. Specifically, the engaging member 32 of the first locking member 3 is configured as a locking pin, and the second locking member 4 is configured as a locking groove into which the locking pin can be inserted. The outlet of the locking groove 4 is located on the side facing the first connecting member 1. Thus, moving the first locking member 3 away from the second connecting member 2 causes the engaging member 32 to disengage from the second locking member 4, that is, the first locking member disengages from the second locking member. In this embodiment, the other end of the flexible cable 6 extends away from the second connecting member 2 after passing over the pulley 5. Figure 1 (as shown), or, the other end of the flexible cable 6 passes around the pulley 5 and extends via one or more guide wheels 51 toward the second connector 2. Figure 2 (As shown).

[0062] In another embodiment, one end of the flexible cable 6 is connected to the second connecting member 2. When the other end of the flexible cable 5 is pulled, the first locking member 3 moves towards the second connecting member 2, thus disengaging from the second locking member 3. Specifically, the outlet of the locking groove 4 is located on the side away from the first connecting member 1, so that the first locking member 3 can disengage from the second locking member 4 by moving towards the second connecting member 2. In this embodiment, the other end of the flexible cable 6 extends away from the first connecting member 1 after passing over the pulley 5. Figure 3 (as shown), or, the other end of the flexible cable 6 passes around the pulley 5 and extends toward the first connector 1 via one or more guide wheels 51. Figure 4 (As shown).

[0063] This invention discloses a children's product, which includes the above-mentioned connecting structure. The children's product can be a scooter, stroller, crib, rocking chair, high chair, or children's swing, etc.

[0064] like Figures 5 to 16 As shown, this invention discloses a scooter, which includes the aforementioned connecting structure. In this embodiment, the first connecting member 1 of the connecting structure is configured as the front frame of the scooter, and the second connecting member 2 of the connecting structure is configured as the footboard of the scooter. The front side of the footboard 2 is pivotally connected to the front frame 1. The first locking member 3 is relatively movably connected to the front frame 1, and the second locking member 4 is disposed on the footboard. One end of the flexible cable 6 is connected to the front frame 1. A front wheel 10 and a rear wheel 20 are respectively disposed on the lower side of the front frame 1 and the rear lower side of the footboard 2.

[0065] The scooter also includes a rider 7 whose lower end is movably connected to the front frame 1; the other end of the flexible cable 6 is connected to an actuating member 61, which is movably connected to the front frame 1. Moving the rider 7 downward relative to the front frame 1 can activate the actuating member 61, thereby pulling the other end of the flexible cable 6, which in turn pulls the first locking member 3 via the pulley 5, causing the first locking member 3 to disengage from the second locking member 4. In this embodiment, the actuating member 61 is movably connected to the front frame 1, and moving the rider 7 downward relative to the front frame 1 can activate the actuating member 61 to move downward, thereby pulling the other end of the flexible cable 6.

[0066] A rider locking mechanism is provided between the lower side of the rider 7 and the front frame 1 to restrict their relative vertical movement. Unlocking the rider locking mechanism allows the rider 7 to move vertically relative to the front frame 1. The rider locking mechanism can employ any known and feasible structure; however, since it is not the inventive point of this invention, it will not be described in detail here.

[0067] In this embodiment, the front frame 1 includes a riser 11 and a bridge seat 12 connected to the front of the riser 11. The front of the pedal 2 is pivotally connected to the rear of the bridge seat 12. The first locking member 3 is movably connected to the bridge seat 12. One end of the flexible cable 6 is connected to the bridge seat 12. The front wheel 10 is connected to the lower side.

[0068] The bridging seat 12 includes a sleeve 121 sleeved on the lower side of the riser 11 and a bridging member 122 connected to the rear side of the sleeve 121. The front side of the pedal 2 is pivotally connected to the bridging member 122. The first locking member 3 is relatively movable and connected to the bridging member 122. A gap 120 is provided between the inner wall of the sleeve 121 and the outer wall of the riser 11. The actuating member 61 is relatively movable up and down and is disposed in the gap 120. A through hole 1210 is provided on the sleeve 121. The other end of the flexible cable 6 extends into the gap 120 through the through hole 1210 and is connected to the actuating member 61.

[0069] The socket 121 includes a main body 1211 sleeved on the lower side of the riser 11, with a gap 120 between the inner wall of the main body 1211 and the outer wall of the riser 11. The socket 121 also includes two connecting portions 1212 extending from the main body 1211 to one side, the two connecting portions 1212 being spaced apart vertically, and the main body 1211 having a through hole 1210 in the portion between the two connecting portions 1212. The front side of the bridging member 122 is fixedly connected to the two connecting portions 1212.

[0070] Preferably, the scooter further includes a guide member 62 connected to the front frame 1 and disposed between the pulley 5 and the actuating member 61. The other end of the flexible cable 6 passes around the pulley 5, then through the guide member 62, and connects to the actuating member 61, with the flexible cable 6 being tensioned by the guide member 62. Thus, the guide member 62 not only guides the flexible cable 6, facilitating its routing, but also tensions it, preventing it from becoming loose in the middle and affecting subsequent pulling. It also prevents the flexible cable 6 from rubbing against other components of the front frame 1, thus avoiding wear and tear and impacting its performance and lifespan. Preferably, one or more guide members 62 are provided, with at least one guide member 62 located between the two connecting portions 1212 of the sleeve 121. This facilitates the tensioning of the flexible cable 6 and its entry into the gap 120 through the through hole 1210, preventing friction between the flexible cable 6 and the end wall of the through hole 1210, which would otherwise affect its performance and lifespan. The guide member 62 can be a guide wheel that is rotatably connected to the front frame 1 about its central axis, or it can be a fixed shaft that is relatively fixedly connected to the front frame 1.

[0071] In this embodiment, the guide member 62 is connected to the bridging member 122. Specifically, a guide seat 63 is fixedly connected to the bridging member 122. The guide seat 63 has a receiving space with front and rear openings, and the guide member 62 is disposed within the receiving space. The front and rear openings of the receiving space facilitate the other end of the flexible cable 6 to enter the receiving space, be guided by the guide member 62, and after being tensioned, pass through the through hole 1210 and enter the gap 120. Corresponding to the guide member 62 located between the two connecting parts 1212 of the sleeve member 121, the end of the guide seat 63 facing the sleeve member 121 extends into the space between the two connecting parts 1212, thereby facilitating the installation of the guide member. The guide seat 63 includes two connected left and right mounting parts 631 and 632, which together form the receiving space.

[0072] Preferably, the first locking member 3, pulley 5, and guide member 62 are all disposed within the bridging member 122, thereby preventing these components from being easily affected by external objects, thus avoiding affecting the operation of the movable pulley structure.

[0073] In this embodiment, the bridging member 122 includes a top plate 1221 and two side plates 1222 extending downward from the left and right ends of the top plate 1221, respectively. The top plate 1221 and the left and right side plates 1222 together form a space 1223. The first locking member 3, the pulley 5, and the guide member 62 are all disposed in the space 1223.

[0074] The scooter also includes a linkage device disposed between the rider 7 and the front frame 1. This linkage device is driven by the downward-moving rider 7 to move the actuator 61 downward, thereby pulling the pulley 5. In this embodiment, the linkage device includes a first drive member 81 connected to the riser 11 with its lower side movable relative to the riser 11, and a second drive member 82 disposed within the gap 120 and above the actuator 61. The second drive member 82 is connected to the riser 11 and the first drive member 81, and the first drive member 81 and the second drive member 82 can move up and down together relative to the riser 11. The downward-moving rider 7 can drive the first drive member 81 downward. When the first drive member 81 moves downward, the second drive member 82 moves downward along with it, driving the actuator 61 downward. Preferably, the second drive member 82 is ring-shaped and sleeved on the outside of the riser 11.

[0075] In this embodiment, a second elastic reset member 810 is provided between the first driving member 81 and the riser 11. So that after the rider 7 moves upward, the first driving member 81 and the second driving member 82 will move upward and reset under the action of the second elastic reset member 810, thereby facilitating the next operation. Specifically, the riser 11 has a second connecting hole 110 and a second elongated hole 111 on its wall, with the second elongated hole 111 spaced apart below the second connecting hole 110. Correspondingly, the first driving member 81 has a third connecting hole 811 and a third elongated hole 812, with the third elongated hole 812 spaced apart above the third connecting hole 811. One rivet passes through the second driving member 82, the second elongated hole 111, and the third connecting hole 811, while another rivet passes through the second connecting hole 110 and the third elongated hole 812. The second elastic reset member 810 is disposed within the third elongated hole 812, with its lower end abutting against the other rivet and its upper end abutting against the top wall of the third elongated hole 812. Thus, under the action of the second elastic reset member 810, the first driving member 81 and the second driving member 82 maintain an upward moving trend.

[0076] In other embodiments, the second elastic reset member 810 may also be disposed between the second drive member 82 and the riser 11.

[0077] The riser 11 includes a lower branch pipe 112 and an upper branch pipe 113 connected to the upper side of the lower branch pipe 112. The lower side of the driver 7 is movably connected to the upper branch pipe 113. The sleeve 121 is sleeved on the outside of the lower branch pipe 112. The lower side of the first driving member 81 is movably connected to the upper side of the lower branch pipe 113. A gap 120 is provided between the inner wall of the sleeve 121 and the lower branch pipe 112. The connection of the upper branch pipe 113, the lower branch pipe 112, and the sleeve 121 is any known and feasible structure, and is not the inventive point of this invention, so it will not be described in detail here.

[0078] The locking seat 31 is movably connected to the bridging member 122 of the front frame 1. In this embodiment, the mating member 32 is set as a locking pin, and the second locking member 4 is set as a locking groove. When the mating member 32 is inserted into the locking groove 4, the front frame 1 and the pedal 2 are in a relatively locked state and cannot rotate relative to each other.

[0079] A fixing seat is provided on the front side of the pedal 2, the bridging member 122 is pivotally connected to the fixing seat, and the locking groove 4 is provided on the fixing seat. In this embodiment, the fixing seat includes two fixing plates 21 spaced apart, and the rear side of the bridging member 122 is pivotally connected between the two fixing plates 21.

[0080] The first elastic reset member 30 is configured as a spring and is positioned between the locking seat 31 and the bridging member 122. Specifically, in this embodiment, the bridging member 122 has a circular hole 1224, and the locking seat 31 has an elongated hole 33. A rivet 301 passes through the circular hole 1224 and the elongated hole 33. The spring is placed inside the elongated hole 33, with one end abutting against the rivet 301 and the other end abutting against the bottom wall of the elongated hole 33 facing the second locking member 4. Under the action of the first elastic reset member 30, the locking seat 31 moves towards the locking groove. When the mating member 32 aligns with the locking groove, the mating member 32 automatically engages in the locking groove under the action of the first elastic reset member 30, thus making operation more convenient.

[0081] In this embodiment, the two side plates 1222 of the bridging member 122 are also provided with elongated holes 1225 for the locking pin 32 to pass through and cooperate with the locking groove 4.

[0082] To facilitate assembly, the locking seat 31 is provided with a groove 310, and the pulley 5 is placed in the groove 310. A connecting shaft passes through the two side walls of the groove 310 and the center of the pulley 5, thereby connecting the locking seat 31 and the pulley 5. The axis of the connecting shaft is on the same straight line as the central axis of the pulley 5. The pulley 5 rotates relative to the locking seat 31 with the connecting shaft as the rotation axis.

[0083] In other embodiments, the first locking member 3 and the second locking member 4 of the scooter can also be configured with other known and feasible structures, as long as they can satisfy the function of disengaging from the second locking member 4 by moving the first locking member 3.

[0084] When the front frame 1 and the footrest 2 are in a relatively locked state, the scooter of the present invention is locked in the unfolded state and cannot be folded. When the scooter of the present invention is to be folded, the rider locking mechanism is unlocked, and then the rider 7 is moved downward. When the rider 7 moves downward a certain distance, its lower end contacts the upper end of the first drive member 81. Continuing to move the rider 7 downward, the first drive member 81 is pushed and moves downward together, thereby the second drive member 82 also moves downward together. The downward movement of the second drive member 82 will push the actuating member 61 to move downward together. The downward movement of the actuating member 61 will drive the scooter... When the end of the cable 6 connected to the actuating member 61 moves downward, the pulley 5 is pulled by the flexible cable 6. Thus, while the pulley 5 rotates relative to the first locking member 3, it can also move together with the first locking member 3 in the direction of disengaging from the locking groove 4. When the mating member 32 on the locking seat 31 disengages from the locking groove 4, the front frame 1 can rotate relative to the pedal 2, and the relative locking state of the two is unlocked. At this time, rotating the front frame 1 in the direction of the pedal 2 will bring the front frame 1 and the pedal 2 closer together. Since the rider 7 is connected to the front frame 1, the rider 7 and the front frame 1 rotate together and move closer to the pedal 2. The scooter of the present invention is foldable.

[0085] The scooter of this invention adopts the above-mentioned structure, which is equivalent to unlocking the lock between the front frame 1 and the pedal 2 through the principle of movable pulley, so that unlocking is very effortless; in addition, by pressing down the handlebar 7, the flexible cable 6 can be pulled to unlock both the front frame 1 and the pedal 2, so the operation is very convenient.

[0086] like Figures 17 to 23 As shown, the present invention also discloses a stroller, which includes the above-described connecting structure. In this embodiment, a first pivot seat 11' is fixedly connected to one side of the first connector 1', and a second pivot seat 21' is fixedly connected to one side of the second connector 2'. The first pivot seat 11' and the second pivot seat 21' are pivotally connected, thereby achieving the purpose of pivoting the first connector 1' and the second connector 2'.

[0087] The first locking member 3' is coaxially pivotally connected to the first pivot seat 11' and the second pivot seat 21', and the first locking member 3' is movable relative to the first pivot seat 11' and the second pivot seat 21'. Specifically, the first locking member 3' is provided with an elongated hole 30' extending vertically, and the first pivot seat 11' and the second pivot seat 21' are respectively provided with corresponding connecting holes 111' and 211'. A pivot (not shown) passes through the elongated hole 30' of the first locking member 3' and the connecting holes 111' and 211' of the first pivot seat 11' and the second pivot seat 21', thereby connecting the first locking member 3' to the first connecting member 1' and the second connecting member 2' and allowing it to move relative to the first connecting member 1' and the second connecting member 2'. The lower side of the first connecting member 1' is also provided with a corresponding connecting hole 12' for the pivot to pass through. The first elastic reset member (not shown) is disposed in the elongated hole 30', with one end abutting against the pivot and the other end abutting against the wall of the elongated hole 30' facing the second connector 2'. Under the action of the first elastic reset member, the first locking member 3' moves towards the end facing the second locking member and engages with it, thereby locking the first connector 1' and the second connector 2' in a non-rotatable state. The locking seat 31' of the first locking member 3' is coaxially pivotally connected to the first pivot seat 11' and the second pivot seat 21'. The elongated hole 30' is disposed on the locking seat 31', and the second locking member 4' is disposed on the second pivot seat 21'. In this embodiment, the mating part 32' of the first locking member is configured as a locking pin, and the second locking member 4' is configured as a locking groove. When the locking pin is engaged in the locking groove, the first pivot seat 11' and the second pivot seat cannot rotate relative to each other, and both are locked in an unfolded state.

[0088] The locking seat 31' is provided with a circular hole 33' corresponding to the mating part 32'. The mating part 32' passes through the circular hole 33', thereby connecting the mating part 32' with the locking seat 31'.

[0089] Corresponding to the locking groove 4′, the lower side of the first connecting member 1′ is provided with an elongated hole 13′ extending vertically, and the mating member 32′ passes through the locking groove 4′ and the elongated hole 13′. In other embodiments, the mating member may also be integrally formed on the locking seat.

[0090] In this embodiment, the second pivot seat 21′ is also provided with an arc-shaped travel groove 212′, one end of which is connected to the outlet of the locking groove 4′.

[0091] An operating mechanism 7' is provided on the side of the first connector 1' away from the second connector 2'. One end of the flexible cable 6' is connected to the first connector 1', and the other end passes around the pulley 5' and is connected to the operating mechanism.

[0092] In this embodiment, preferably, the first connecting member 1' is tubular, and a mounting member 8' is fixedly connected inside the first connecting member 1' and located on the upper side of the first locking member. One end of the flexible cable 6' is connected to the mounting member 8'. A clearance notch 81' is provided on one side of the mounting member 8', and the other end of the flexible cable 6' passes around the pulley 5', through the clearance notch 81', and then connects to the operating mechanism 7'.

[0093] In this embodiment, a receiving space 111' is provided on the lower side of the first pivot seat 11', and the upper side of the second pivot seat 21' extends into the receiving space 111' and connects with the first pivot seat 11' and the first locking member 3'.

[0094] Preferably, the lower side of the first connector 1' also extends into the accommodating space 111', and a notch 14' is provided in the middle of the lower side of the first connector 1', and the upper side of the second pivot seat 21' extends into the notch 14'.

[0095] The first pivot seat 11′ is connected to the cover body 15′ and 16′ on the left and right sides respectively.

[0096] When the first connector 1' and the second connector 2' are to be folded, the operating mechanism 7' is driven, thereby pulling the other end of the flexible cable 6'. The pulley 5' is pulled by the flexible cable 6', causing the pulley 5' to rotate around its central axis and move together with the first locking member 3', thereby driving the mating member 32' to move upward and disengage from the locking groove, thus disengaging the first locking member 3' from the second locking member 4'. At this time, the first connector 1' and the second connector 2' can rotate relative to each other, that is, the relative locking state of the first connector 1' and the second connector 2' is unlocked. After the mating member 32' moves upward and disengages from the locking groove, it will enter the arc-shaped travel groove 212', rotating the first connector 1' in the extension direction of the arc-shaped travel groove 212' until the first connector 1' and the second connector 2' are close together (not shown in the figure), thereby making the first connector 1' and the second connector 2' folded and close together. During the rotation of the first connecting member 1′, the first locking member 3′ rotates together with the first connecting member 1′, and the mating member 32′ rotates and moves along the arc-shaped travel groove 212′. The specific structure of the operating mechanism and the technology by which it pulls the flexible cable are any known and feasible technologies, and therefore will not be described in detail here.

[0097] As described above, because the stroller of the present invention adopts the above-mentioned connection structure, it is equivalent to unlocking the lock between the first connector 1′ and the second connector 2′ through the principle of movable pulley, so unlocking is very effortless; in addition, the lock between the first connector 1′ and the second connector 2′ can be released by simply manipulating the operating mechanism 7′ on the first connector 1′ and pulling the flexible rope 6′, so the operation is also very simple.

[0098] In one embodiment, such as Figure 24 As shown, the stroller also includes a base support 100' extending forward and backward. The lower side of the first connecting member 1' is pivotally connected to the upper side of the second connecting member 2', and the lower side of the second connecting member 2' is pivotally connected to the front side of the base support 100'. The first connecting member 1', the second connecting member 2', and the base support 100' together form a ∠ shape. That is to say, the first connecting member 1' is configured as the handlebar of the stroller of the present invention, and the second connecting member 2' is configured as the lower support of the stroller of the present invention.

[0099] The lower front part of the base bracket 100' is provided with a front wheel, and the lower rear part is provided with a rear wheel (not shown in the figure).

[0100] In another embodiment, such as Figure 25 As shown, the stroller also includes a front support 91' and a rear support 92'. The lower side of the first connecting member 1' is pivotally connected to the upper side of the second connecting member 2'. Of the rear side of the front support 91', the lower side of the second connecting member 2', and the front side of the rear support 92', two are pivotally connected, and the third is pivotally connected to one of the aforementioned two, or the three are coaxially pivotally connected. That is to say, the first connecting member 1' is configured as the upper arm of the stroller of the present invention, and the second connecting member 2' is configured as the lower arm of the stroller of the present invention.

[0101] The front support 91' is connected to the lower front part of the front wheel 10', and the rear support 92' is connected to the lower rear part of the rear wheel 20'. In other embodiments, in addition to the aforementioned connecting structure, the stroller may include other feasible components, thereby allowing the stroller to form other different shapes as a whole.

[0102] like Figure 26 , 27 As shown in Figures 28 and 29, the present invention also discloses a crib, which includes the above-described connecting structure.

[0103] The crib also includes multiple spaced side support members 100 and a bottom support 200 connected to the lower side of the multiple side support members. An armrest 300 is connected to the upper side of each adjacent side support member 100. The first connector 1-1 and the second connector 2-1 of the connection structure are set as the two armrest tubes of the armrest 300.

[0104] In this embodiment, the specific structure between the first connecting member and the second connecting member can be the same as that of the first connecting member and the second connecting member in the aforementioned stroller. That is, a first pivot seat is fixedly connected to one side of one of the two armrest tubes 1-1, and a second pivot seat is fixedly connected to one side of the other armrest tube 2-1. The first pivot seat and the second pivot seat are pivotally connected. The first locking member is coaxially pivotally connected to the first pivot seat and the second pivot seat, and the first locking member can move relative to the first pivot seat and the second pivot seat. The second locking member is disposed on the second pivot seat.

[0105] An operating element 400 is provided on the side of one of the handrail tubes 1-1 away from the other handrail tube 2-1. One end of the flexible cable 6-1 is connected to one of the handrail tubes 1-1, and the other end passes around the pulley and is connected to the operating element 400.

[0106] An installation component is fixedly connected inside one of the armrest tubes and located between the first locking component and the operating component. One end of the flexible cable is connected to the installation component. A clearance notch is provided on one side of the installation component. The other end of the flexible cable passes around the pulley, passes through the clearance notch, and then connects to the operating component. Preferably, the second pivot seat is also provided with an arc-shaped travel groove. The outlet end of the arc-shaped travel groove communicates with the outlet end of the locking groove (see the illustration of the stroller embodiment for details).

[0107] When the crib of the present invention needs to be folded, the operating member 400 is moved away from the second connecting member 2-1. The pulley drives the first locking member to move and disengage from the second locking member, thereby allowing the first connecting member 1-1 and the second connecting member 2-1 to rotate relative to each other, and thus folding the crib.

[0108] Because the lock between the first connecting member 1-1 and the second connecting member 2-1 is unlocked via a movable pulley, the unlocking operation is very effortless; and simply moving the operating member 400 to one side is sufficient to unlock the lock between the first connecting member 1-1 and the second connecting member 2-1, making the unlocking operation very convenient. The above only describes in detail an embodiment of the connecting structure of the present invention used in scooters, strollers, and cribs, and the first connecting member and the second connecting member are rotatably connected. Those skilled in the art should understand that the connecting structure of the present invention can also be used in other children's products, and the first connecting member and the second connecting member can be relatively movable connected, as the principle is the same, and therefore will not be listed here individually.
