When an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for illustrative purposes and are not the only embodiment.

[0034] The present application discloses a connection mechanism and a carrier comprising the connection mechanism. Specifically, the carrier comprises a carrier body, and the connection mechanism is connected to the carrier body. Wherein, the carrier is, for example, a cart, a trailer, and the connection mechanism is a push rod of the cart; or the carrier is, for example, a car seat, a baby bed, a rocking chair, and the connection mechanism is a supporting leg of the car seat, a supporting seat of the baby bed or the rocking chair. At this time, the connection mechanism can also be set as a part of the carrier.

[0035] As Figures 1 to 3As shown, the connecting mechanism comprises a first connecting member 1, a second connecting member 2 and a movable assembly, the second connecting member 2 is in sliding connection with the first connecting member 1, and the first connecting member 1 and the second connecting member 2 have a locked state and an unlocked state to adjust the length of the connecting mechanism. In the embodiment, the first connecting member 1 and the second connecting member 2 are both in the shape of a rod, forming a connecting rod structure. Specifically, the first connecting member 1 is a middle push rod of the connecting mechanism, and the second connecting member 2 is an upper push rod of the connecting mechanism, the end of the second connecting member 2 is inserted into the first connecting member 1 and can slide in and out of the first connecting member 1, forming an extension rod structure.

[0036] The movable assembly is movably arranged on one of the first connecting member 1 and the second connecting member 2, and has a first position and a second position. When the movable assembly is in the first position (i.e., when the first connecting member 1 and the second connecting member 2 are in the locked state), the movable assembly can abut against the other one of the first connecting member 1 and the second connecting member 2 to prevent the first connecting member 1 and the second connecting member 2 from moving relative to each other. When the movable assembly is in the second position (i.e., when the first connecting member 1 and the second connecting member 2 are in the unlocked state), the movable assembly is disengaged from the other one of the first connecting member 1 and the second connecting member 2, and the first connecting member 1 and the second connecting member 2 can move relative to each other. In the present embodiment, the movable assembly is arranged on the second connecting member 2, and the first connecting member 1 and the second connecting member 2 are both sleeves, and the end of the second connecting member 2 is arranged in the first connecting member 1; when the movable assembly is disengaged from the other one of the first connecting member 1 and the second connecting member 2, the end of the second connecting member 2 can smoothly slide in and out of the first connecting member 1.

[0037] With the size of the first connecting member 1 and the second connecting member 2 unchanged, the movable assembly abuts against the first connecting member 1 in the locked state to prevent the first connecting member 1 and the second connecting member 2 from moving relative to each other, so that the connecting mechanism is more stable and the user experience is better. After the movable assembly is disengaged, the sufficient gap between the first connecting member 1 and the second connecting member 2 can ensure that the second connecting member 2 can smoothly slide in and out of the first connecting member 1, so that the folding and extension efficiency is higher and the use is more labor-saving.

[0038] The specific structure for realizing the locked state between the first connecting member 1 and the second connecting member 2 is not limited, and the structure for locking two connecting rods that can slide relative to each other in the prior art can be used. In the present embodiment, the connecting mechanism further comprises a locking structure arranged between the first connecting member 1 and the second connecting member 2. When the locking structure is in the locked state, the first connecting member 1 and the second connecting member 2 are locked, the movable assembly is in the first position, and the first connecting member 1 and the second connecting member 2 are prevented from moving relative to each other; when the locking structure is in the unlocked state, the first connecting member 1 can slide relative to the second connecting member 2, and the movable assembly is in the second position.

[0039] In other embodiments, the first connecting member 1 and the second connecting member 2 can also be in other structures such as plate-shaped or strip-shaped, and no locking structure can be arranged between the first connecting member 1 and the second connecting member 2. When the first connecting member 1 and the second connecting member 2 are unfolded, the movable assembly is arranged to form a block between the first connecting member 1 and the second connecting member 2. When the first connecting member 1 and the second connecting member 2 need to be relatively moved, a larger force can be applied to the first connecting member 1 or the second connecting member 2 to remove the block of the movable assembly, so that the first connecting member 1 and the second connecting member 2 can be relatively slid. For example, the connecting structure can be a drawer structure.

[0040] Specifically, the connecting mechanism includes a locking member 7, a handle 8 and a locking member reset spring 9 arranged on the second connecting member 2, and a locking hole 11 is arranged on the first connecting member 1. The locking member reset spring 9 can push the locking member 7 to move towards the locking hole 11.

[0041] When the locking member 7 is clamped into the locking hole 11, the second connecting member 2 can be fixed relative to the first connecting member 1. Pressing the handle 8 can make the locking member 7 move in the direction of compressing the locking member reset spring 9. After the locking member 7 is separated from the locking hole 11, the second connecting member 2 can be slid into and out of the first connecting member 1. The control structure of the handle 8 on the locking member 7 is not limited. Structures in the prior art that can make the structure connected thereto move by pressing a structure can be used.

[0042] The specific structure of the movable assembly is not limited. It can be in an abutting state when the first connecting member 1 and the second connecting member 2 are in a locked state, and the abutting state is removed when the first connecting member 1 and the second connecting member 2 are in an unlocked state. In the present embodiment, as shown in Figure 4 The movable assembly includes a movable member 3. The movable member 3 has a first end and a second end. The first end is rotationally connected to the second connecting member 2 around a rotating shaft 35. When the movable assembly is in a first position, the second end abuts against the first connecting member 1. The rotating shaft 35 is coaxially arranged with the hinge hole 31. The movable member 3 can rotate around the axis of the hinge hole 31 (the rotating shaft 35).

[0043] Specifically, when the first connecting member 1 and the second connecting member 2 are in a locked state, the movable member 3 rotates around the rotating shaft 35 towards the direction of approaching the inner wall surface of the first connecting member 1 until the outer peripheral surface of the movable member 3 abuts against the inner wall surface of the first connecting member 1. When the first connecting member 1 and the second connecting member 2 are in an unlocked state, the movable member 3 rotates around the rotating shaft 35 away from the inner wall surface of the first connecting member 1 until the outer peripheral surface of the movable member 3 is completely separated from the inner wall surface of the first connecting member 1.

[0044] The specific shape of the movable component 3 is not limited, as long as the distance between the outer periphery of the movable component 3 and the center of the hinge hole 31 is not equal, and the distance between the outer periphery of the movable component 3 and the inner wall surface of the first connecting component 1 changes when the movable component 3 rotates around the hinge hole 31. When the movable component 3 firmly abuts against the inner wall surface of the first connecting component 1, it is equivalent to that there is no gap between the first connecting component 1 and the second connecting component 2, the first connecting component 1 and the second connecting component 2 will not shake in the radial direction, and the overall structure composed of the first connecting component 1 and the second connecting component 2 is more stable, and the use experience is good.

[0045] The specific structure for realizing the disengagement of the movable assembly from abutting against the other one of the first connecting component 1 and the second connecting component 2 is not limited, and in the embodiment, as shown in Figure 2 , the movable assembly further comprises an automatic reset component 4, which can be but is not limited to a spring, and can apply a force to the movable component 3 to reset it.

[0046] The automatic reset component 4 is connected between one of the first connecting component 1 and the second connecting component 2 and the movable component 3, and is used to drive the movable component 3 to move towards the second position. That is, when an external force pushes the movable component 3 to rotate in the direction close to the inner wall surface of the first connecting component 1, the automatic reset component 4 is compressed; when the external force pushing the movable component 3 is removed, the automatic reset component 4 can push the movable component 3 to rotate around the rotating shaft 35 in the direction away from the inner wall surface of the first connecting component 1.

[0047] As shown in Figure 2 , Figure 4 , Figure 6 and Figure 7 , a mounting blind hole 32 is formed on the movable component 3, one of the first connecting component 1 and the second connecting component 2 is provided with a limiting base 5, and the movable component 3 is rotatably arranged on the limiting base 5. The automatic reset component 4 is arranged in the mounting blind hole 32, one end of the automatic reset component 4 abuts against the end face of the mounting blind hole 32, and the other end of the automatic reset component 4 abuts against the limiting base 5.

[0048] The specific setting position of the automatic reset component 4 is not limited, as long as it always has the tendency to push the movable component 3 to rotate around the rotating shaft 35 in the direction away from the inner wall surface of the first connecting component 1. In the embodiment, the hinge hole 31 is formed on the movable component 3, the movable component 3 can rotate around the axis direction of the hinge hole 31, and the automatic reset component 4 is located between the first connecting component 1 and the hinge hole 31, which is reasonable in structure and small in space occupation, and the spring force on the automatic reset component 4 is as much as possible to be applied to the movable component 3, so that the utilization rate of the spring force is high.

[0049] The specific setting position of the movable component 3 is not limited, and in the embodiment, the movable component 3 is arranged at the end of the second connecting component 2, so that the structure on the second connecting component 2 except the end can be fully utilized.

[0050] The specific shape of the movable member 3 is not limited, and can be circular with the hinge hole 31 eccentrically arranged, or non-circular, as long as the distance from the outer periphery of the movable member 3 to the center of the hinge hole 31 is not constant. In the embodiment, the outer periphery of the movable member 3 is non-circular, and the movable member 3 is formed with an abutting surface 33 for abutting against the first connecting member 1. In order to avoid the movable member 3 and the first connecting member 1 from being locked, the abutting surface 33 is at least partially arc-shaped.

[0051] When the movable member 3 rotates around the rotation shaft 35 towards the direction of approaching the inner wall surface of the first connecting member 1, the arc-shaped abutting surface 33 can smoothly slide relative to the inner wall surface of the first connecting member 1, until the outer periphery of the movable member 3 firmly abuts against the inner wall surface of the first connecting member 1. When the movable member 3 rotates around the rotation shaft 35 towards the direction of moving away from the inner wall surface of the first connecting member 1, the arc-shaped abutting surface 33 can again smoothly slide relative to the inner wall surface of the first connecting member 1, until the outer periphery of the movable member 3 completely separates from the inner wall surface of the first connecting member 1.

[0052] The source of the external force for pushing the movable member 3 to rotate towards the direction of approaching the inner wall surface of the first connecting member 1 is not limited, and a limiting protrusion (not shown) can be arranged on the inner wall surface of the first connecting member 1. When the first connecting member 1 and the second connecting member 2 are in the locked state, the limiting protrusion can push the movable member 3 towards the direction of moving away from the second connecting member 2, so that the movable member 3 rotates towards the direction of approaching the inner wall surface of the first connecting member 1, until the movable member 3 firmly abuts against the inner wall surface of the first connecting member 1.

[0053] A limiting base 5 is arranged on one of the first connecting member 1 and the second connecting member 2, and an end of the limiting base 5 is provided with a limiting portion which can cooperate with the limiting member 6 or the limiting protrusion to prevent the first connecting member 1 and the second connecting member 2 from being separated.

[0054] On the basis of the above structure, the first connecting member 1 is slidingly sleeved on the outside of the second connecting member 2, the first end is rotationally connected to the second connecting member 2 around the rotation shaft, and the second end abuts against the inner side wall of the first connecting member 1 when the movable assembly is in the first position. When the movable assembly moves from the first position to the second position, the movable member 3 rotates towards the direction of moving away from the inner side wall of the first connecting member. In other embodiments, the second connecting member 2 can be slidingly sleeved on the outside of the first connecting member 1, and the first section of the movable member 3 is rotationally connected to the first connecting member 1. When the movable assembly is in the first position, the second end abuts against the inner side wall of the second connecting member 2. When the movable assembly moves from the first position to the second position, the movable member 3 rotates towards the direction of moving away from the inner side wall of the second connecting member 2.

[0055] In the embodiment, as shown in FIG. 1, the first connecting member 1 is provided with a limiting protrusion 4, and the second connecting member 2 is provided with a limiting member 6 which is in cooperation with the limiting protrusion 4. Figure 3As shown, the first connecting piece 1 is internally provided with a limiting piece 6, and the end face 61 of the limiting piece 6 has the same function as the limiting protrusion in the previous scheme. When the first connecting piece 1 and the second connecting piece 2 are in the locked state, the end face 61 of the limiting piece 6 can push the movable piece 3 away from the second connecting piece 2, so as to rotate the movable piece 3 towards the inner wall surface of the first connecting piece 1 until the movable piece 3 firmly abuts against the inner wall surface of the first connecting piece 1. The limiting piece 6 is in a split structure with the first connecting piece 1, which is convenient for processing and has low manufacturing difficulty. In addition, in the present embodiment, the limiting piece 6 is arranged between the first connecting piece 1 and the second connecting piece 2, which can reduce the gap between the two connecting rods and prevent shaking.

[0056] In order to further avoid relative shaking between the first connecting piece 1 and the second connecting piece 2, the connecting mechanism comprises at least two groups of movable assemblies, and all the movable assemblies can abut against the first connecting piece 1 from different positions respectively. In the present embodiment, as shown in Figures 5 to 7 two movable pieces 3 are arranged back to back on the second connecting piece 2, and the two movable pieces 3 can abut against the inner wall surface of the first connecting piece 1 from opposite sides respectively, and apply force from two opposite directions, so that the first connecting piece 1 and the second connecting piece 2 do not shake in the radial direction when in the locked state. In other embodiments, for example, a plurality of groups of movable assemblies can be arranged in a length extension manner along the first connecting piece 1 or the second connecting piece 2 or in other directions, so as to increase the stability between the two connecting assemblies.

[0057] Figure 5 As shown, the first connecting piece 1 and the second connecting piece 2 are in the locked state, the locking piece 7 is clamped in the locking hole 11, the end face 61 of the limiting piece 6 presses the movable piece 3, the movable piece 3 rotates around the rotating shaft 35 towards the inner wall surface of the first connecting piece 1, and the outer periphery of the two movable pieces 3 firmly abut against the inner wall surface of the first connecting piece 1 from two directions respectively.

[0058] Figure 6 As shown, the first connecting piece 1 and the second connecting piece 2 start to release the locked state (start to be in the unlocked state), the locking piece 7 just leaves the locking hole 11, the end face 61 of the limiting piece 6 is basically separated from the movable piece 3, and the automatic reset piece 4 pushes the movable piece 3 towards the second connecting piece 2, as shown in Figure 6 The curved line with an arrow in the figure shows the rotating direction of the movable piece 3 around the rotating shaft 35.

[0059] Figure 7 As shown, the first connecting piece 1 and the second connecting piece 2 completely release the locked state (completely in the unlocked state), the second connecting piece 2 slides into the first connecting piece 1, the locking piece 7 completely leaves the locking hole 11, the end face 61 of the limiting piece 6 is away from the movable piece 3, and the automatic reset piece 4 continues to push the movable piece 3 towards the second connecting piece 2, and the movable piece 3 rotates around the rotating shaft 35 away from the inner wall surface of the first connecting piece 1.Figure 7 The rotation direction of the movable member 3 around the rotation shaft 35 is indicated by the curved line with a middle arrow.
