[0075] This embodiment provides an unlocking structure that can be used in armrest assemblies to solve the problem that the unlocking process in existing technologies is too cumbersome and not simple or convenient when releasing the locking mechanism from the armrest assembly. Of course, this unlocking structure is not limited to armrest assemblies, but can also be used in other connecting components that require unlocking, such as unlocking the backrest, seat, etc. of a stroller from the frame.

[0076] like Figures 1 to 20 As shown, the unlocking structure provided in this embodiment is mounted on the mounting part of the vehicle and includes an operating component 1, a first connecting component 2, a second connecting component 3, a first locking component 4, and a second locking component 5. The mounting part has a receiving space for accommodating the operating component 1, the first connecting component 2, and the second connecting component 3. The operating component 1 is located at the outermost edge of the receiving space and can move relative to the receiving space, for example, it can move or rotate. Part of the operating component 1 is exposed outside the receiving space for user operation. The first connecting component 2 and the second connecting component 3 are respectively movably disposed within the receiving space. When the operating component 1 is activated, it can simultaneously drive the first connecting component 2 and the second connecting component 3 to move. The first connecting component 2 is connected to the first locking component 4 and can drive the first locking component 4 to unlock with the corresponding locking component. The second connecting component 3 is connected to the second locking component 5 and can drive the second locking component 5 to unlock with the corresponding locking component. This embodiment can simultaneously unlock the first locking component 4 and the second locking component 5 by activating the operating component 1. Its structure is simple, the operation is convenient and quick, the linkage is good, and the unlocking efficiency is effectively improved.

[0077] Optionally, in this embodiment, the operating member 1 is along the first direction (i.e. Figure 1 The first connecting member 2 is movably installed in the accommodating space (vertically). The first connecting member 2 is located below the operating member 1, and the second connecting member 3 is located below the first connecting member 2. The first connecting member 2 and the second connecting member 3 are rotatably installed in the accommodating space. Specifically, the first connecting member 2 and the second connecting member 3 rotate around the same axis, and the rotation axes of the first connecting member 2 and the second connecting member 3 are parallel to the first direction. The unlocking structure also includes a first driving structure disposed between the operating member 1 and the first connecting member 2, and a second driving structure disposed between the operating member 1 and the second connecting member 3. When the operating member 1 moves along the first direction, it can drive the first connecting member 2 to rotate through the first driving structure, and can drive the second connecting member 3 to rotate through the second driving structure. When the first connecting member 2 rotates, it can drive the first locking member 4 to unlock, and when the second connecting member 3 rotates, it can drive the second locking member 5 to unlock. Optionally, both the first driving structure and the second driving structure are wedge structures. In this embodiment, the movement of the operating member 1 is converted into the rotation of the first connecting member 2 and the second connecting member 3 through the wedge structure. Its movement is smooth and reliable, effectively saving the space occupied by the unlocking structure, and is convenient for user operation. Furthermore, the operating element 1 is a button, and the user only needs to press the button to unlock the first locking element 4 and the second locking element 5 simultaneously.

[0078] It should be noted that in other embodiments, the operating member 1 can move in the vertical direction, and the first connecting member 2 and the second connecting member 3 can move in the horizontal direction respectively, with the first connecting member 2 and the second connecting member 3 located on both sides below the operating member 1. When the operating member 1 moves in the vertical direction, it can drive the first connecting member 2 to move horizontally through the first wedge structure, and it can drive the second connecting member 3 to move horizontally through the second wedge structure. In this way, the first locking member 4 and the second locking member 5 can be unlocked at the same time, and it is not limited to this embodiment.

[0079] Optionally, the first driving structure of this embodiment includes a first inclined surface 11 disposed at the bottom of the operating member 1 and a second inclined surface 21 disposed at the top of the first connecting member 2. The first inclined surface 11 and the second inclined surface 21 cooperate with each other, and the first connecting member 2 can be driven to rotate by pressing the operating member 1. Further, in order to facilitate the driving of the second connecting member 3 by the operating member 1, this embodiment also provides a third connecting member 6. The third connecting member 6 is movably disposed in the accommodating space along the first direction. The third connecting member 6 is located below the first connecting member 2 and above the second connecting member 3. That is, the operating member 1, the first connecting member 2, the third connecting member 6 and the second connecting member 3 are arranged sequentially from top to bottom along the first direction. By pressing the operating member 1 along the first direction, the third connecting member 6 can be pushed to move along the first direction. When the third connecting member 6 moves, it can push the second connecting member 3 to rotate. In this embodiment, the second driving structure is disposed between the third connecting member 6 and the second connecting member 3. The second driving structure includes a third inclined surface 61 disposed at the bottom of the third connecting member 6 and a fourth inclined surface 31 disposed at the top of the second connecting member 3. The third inclined surface 61 and the fourth inclined surface 31 cooperate with each other. By pressing the operating member 1, the third connecting member 6 can be driven to move along the first direction, thereby driving the second connecting member 3 to rotate. The above-described first driving structure and second driving structure are simple in structure, reliable in cooperation, and easy to process.

[0080] Of course, in other alternative embodiments, a wedge structure can be directly set between the operating member 1 and the second connecting member 3, so that the second connecting member 3 can be directly driven to rotate by the operating member 1. In this case, it is only necessary to set an inclined surface at the bottom of the operating member 1 and another matching inclined surface at the top of the second connecting member 3, and it is not limited to this embodiment.

[0081] Optionally, in this embodiment, the bottom of the operating member 1 extends downward with an arc-shaped wall 12, the bottom surface of which has a first inclined surface 11, and one end of the arc-shaped wall 12 has a downwardly extending abutment post 13; the top of the first connecting member 2 has an arc-shaped groove 22, the arc-shaped groove 22 has a second inclined surface 21, and the bottom of the arc-shaped groove 22 has a through hole 23, through which the abutment post 13 passes and abuts against the top of the third connecting member 6. Preferably, there are two arc-shaped walls 12, which are evenly arranged along the circumference of the operating member 1; there are also two arc-shaped grooves 22, which are evenly arranged along the circumference of the first connecting member 2, so as to better drive the first connecting member 2 to rotate. Further, the bottom of the third connecting member 6 has a protruding protrusion 63, the bottom surface of which is a third inclined surface 61; the outer periphery of the second connecting member 3 has a connecting seat 33, and the connecting seat 33 has a fourth inclined surface 31. Preferably, there are two protrusions 63, evenly arranged along the circumference of the third connector 6; there are also two connecting seats 33, evenly arranged along the circumference of the second connector 3, which can better drive the second connector 3 to rotate. In this embodiment, when the operating member 1 moves downward, the first connector 2 can be rotated through the cooperation of the first inclined surface 11 and the second inclined surface 21; at the same time, the third connector 6 can be driven to move downward through the pushing action of the abutment post 13, and then the second connector 3 can be rotated through the cooperation of the third inclined surface 61 and the fourth inclined surface 31. This embodiment has a compact structure and reasonable arrangement. By pressing the operating member 1, the first connector 2, the third connector 6, and the second connector 3 can be linked simultaneously, so that the first locking member 4 and the second locking member 5 can be unlocked at the same time, which is convenient to operate and improves efficiency.

[0082] In some possible embodiments, the vehicle further includes a first structural member and a second structural member connected together, with a mounting portion disposed between the first and second structural members. A third connecting member 6 is also used to lock the first and second structural members together. When the operating member 1 drives the third connecting member 6 downward, the first and second structural members can be unlocked. When the operating member 1 moves along a first direction, it drives the first connecting member 2 to rotate, thereby unlocking the first locking member 4. Simultaneously, it drives the third connecting member 6 to move along the first direction, thereby releasing the first and second structural members from locking, and also drives the second connecting member 3 to rotate, thereby unlocking the second locking member 5. This configuration allows for simultaneous unlocking at three locations by pressing the operating member 1, making operation simpler and unlocking more efficient. Furthermore, the first locking member 4 is connected to the first connecting member 2 via a first traction member, and the second locking member 5 is connected to the second connecting member 3 via a second traction member, resulting in a simple structure and reliable connection. The first and second traction members are respectively traction cables.

[0083] Furthermore, in this embodiment, the first locking member 4 and the second locking member 5 are located on opposite sides of the operating member 1 and move towards each other during unlocking. When the operating member 1 moves to drive the first connecting member 2 and the second connecting member 3 to rotate, the first connecting member 2 and the second connecting member 3 rotate in opposite directions. This arrangement is more convenient and simpler in structure than having the first connecting member 2 and the second connecting member 3 rotate in the same direction, making it easier to unlock the first locking member 4 and the second locking member 5. Of course, in other embodiments, the first connecting member 2 and the second connecting member 3 can rotate in the same direction, which can also achieve the unlocking of the first locking member 4 and the second locking member 5.

[0084] Furthermore, in this embodiment, a positioning post 14 extending along the first direction is provided at the bottom of the operating member 1, and a positioning hole 24 is provided at the top of the first connecting member 2. The positioning post 14 is inserted into the positioning hole 24. This not only ensures the accuracy of the assembly between the operating member 1 and the first connecting member 2, and the reliability of the movement of the operating member 1 along the first direction, but more importantly, the positioning post 14 can serve as the pivot of the first connecting member 2, ensuring the accuracy and stability of the rotation of the first connecting member 2.

[0085] This embodiment also provides a connecting component that can be used in strollers, baby carriages, cribs, children's vehicles, or other carriers. Exemplarily, the connecting component can be a foldable armrest. The connecting component has an unfolded state and a folded state, and includes a first support 100, a second support 200, a third support 300, and a fourth support 400. The first end of the first support 100 and the first end of the second support 200 are rotatably connected about a first axis 102. The second end of the first support 100 is rotatably connected to the third support 300 about a second axis 301, and the second end of the second support 200 is rotatably connected to the fourth support 400 about a third axis 401. With this configuration, when the connecting component needs to be folded, the first support 100 and the second support 200 can be rotated and folded about the first axis 102, thereby causing the third support 300 and the fourth support 400 to move closer together, thus reducing the lateral dimension of the connecting component and achieving folding of the connecting component. Optionally, the first axis 102, the second axis 301, and the third axis 401 all extend along the first direction and are arranged parallel to each other. This allows the first support 100 and the second support 200, the third support 300 and the first support 100, and the fourth support 400 and the second support 200 to rotate in the same plane, ensuring the convenience of the folding and unfolding process of the connecting assembly, while improving the reliability of use in the unfolded state.

[0086] Furthermore, the connecting assembly also includes the unlocking structure described above. The mounting portion is located at the rotatable connection between the first bracket 100 and the second bracket 200. The first locking member 4 is movably disposed on the first bracket 100, used to lock the rotation between the first bracket 100 and the third bracket 300. The second locking member 5 is movably disposed on the second bracket 200, used to lock the rotation between the second bracket 200 and the fourth bracket 400. The operating member 1 is actuated to unlock the first locking member 4 and the second locking member 5. In this embodiment, when the connecting assembly is in the unfolded state, the first bracket 100, the second bracket 200, the third bracket 300, and the fourth bracket 400 cannot rotate, improving the reliability and safety of the connecting assembly. Pressing the operating member 1 can simultaneously unlock the first locking member 4 and the second locking member 5, allowing the first bracket 100 to rotate relative to the third bracket 300 and the second bracket 200 to rotate relative to the fourth bracket 400. This facilitates folding the connecting assembly, reducing its size and making it easier to store and carry. This embodiment has a simple structure, is easy to unlock, has good linkage, and effectively improves unlocking efficiency.

[0087] Optionally, the first locking element 4 includes a first locking tongue 41, a first resetting element, and a first traction cable. The second end of the first bracket 100 is provided with a first locking tongue cavity 103, and the first locking tongue 41 is retractably disposed within the first locking tongue cavity 103. The third bracket 300 is provided with a first locking groove, and the first locking tongue 41 can be inserted into the first locking groove to lock the first bracket 100 and the third bracket 300. The first resetting element is disposed within the first locking tongue cavity 103 and connected to the first locking tongue 41, used to keep the first locking tongue 41 extended from the first locking tongue cavity 103 for locking with the third bracket 300. Preferably, in this embodiment, the first resetting element is a compression spring, which has a simple structure and reliable resetting.

[0090] Furthermore, the connecting assembly also includes a third connector 6, which is movably disposed within the mounting portion along a first direction. When the third connector 6 is in the first position, it engages with both the first bracket 100 and the second bracket 200, thereby locking the rotation between the first bracket 100 and the second bracket 200. When the third connector 6 moves to the second position, it engages only with the second bracket 200, thereby unlocking the first bracket 100 and the second bracket 200.

[0091] Optionally, when the unlocking structure is in the locked state, the third connector 6 is in the first position, and the connecting component is in the unfolded state, thereby ensuring the stability and reliability of the connecting component during normal use; when the operating component 1 drives the unlocking structure to unlock, the first locking component 4 and the second locking component 5 are unlocked, and the third connector 6 moves to the second position, at which time the connecting component can be converted to a folded state for storage and carrying.

[0092] Specifically, the third connector 6 is a toothed member with a toothed portion 62 on its outer periphery; the first end of the first bracket 100 is provided with a first toothed groove, and the first end of the second bracket 200 is provided with a second toothed groove; when the third connector 6 is in the first position, the toothed portion 62 cooperates with the first toothed groove and the second toothed groove respectively to lock the first bracket 100 and the second bracket 200; when the third connector 6 moves to the second position, the third connector 6 is fully inserted into the first end of the second bracket 200, and the toothed portion 62 only cooperates with the second toothed groove to unlock the first bracket 100 and the second bracket 200.

[0093] In this embodiment, a first mounting cavity 101 is provided at the upper part of the first end of the first bracket 100, and the first end of the second bracket 200 is located below the first end of the first bracket 100, with a second mounting cavity 201 formed between the two. An operating member 1 is movably mounted in the first mounting cavity 101 along a first direction, and a first connecting member 2 is rotatably mounted in the first mounting cavity 101, with the operating member 1 located above the first connecting member 2. When the operating member 1 moves along the first direction, it can drive the first connecting member 2 to rotate through a first driving structure, thereby unlocking the first locking member 4. A third connecting member 6 is movably mounted in the second mounting cavity 201 along the first direction, and a second connecting member 3 is rotatably mounted in the second mounting cavity 201, with the third connecting member 6 located above the second connecting member 3. When the third connecting member 6 moves along the first direction, it can drive the second connecting member 3 to rotate through a second driving structure, thereby unlocking the second locking member 5. In this embodiment, the third connecting member 6 has two functions: firstly, it is used to lock and unlock the first bracket 100 and the second bracket 200; secondly, when the third connecting member 6 moves downward, it can push the second connecting member 3 to rotate, thereby unlocking the second locking member 5. In other words, this embodiment allows the first locking member 4, the second locking member 5, and the third connecting member 6 to move simultaneously by pressing the operating member 1, thus achieving unlocking of all three positions with a single button press. This simplifies operation and greatly improves unlocking efficiency. This embodiment uses a first driving structure to convert the movement of the operating member 1 into the rotation of the first connecting member 2, and a second driving structure to convert the movement of the third connecting member 6 into the rotation of the second connecting member 3. This ensures smooth and reliable movement, effectively saves space occupied by the unlocking structure, and facilitates user operation. The specific settings of the first and second driving structures are described above and will not be repeated here.

[0094] Furthermore, the operating component 1 is provided with several connecting arms 15 extending along the first direction on the side facing the first connecting component 2, and each connecting arm 15 has a hook 151 at its end; the first end of the first bracket 100 is also provided with a connecting hole, through which the connecting arm 15 can pass from the connecting hole into the second mounting cavity 201 from the first mounting cavity 101, and the hook 151 is engaged in the second mounting cavity 201. This arrangement can effectively prevent the operating component 1 from detaching from the accommodating space, and the connecting arms 15 can also guide the movement of the operating component 1, improving the accuracy of the movement. Preferably, in this embodiment, the operating component 1 is provided with four connecting arms 15 evenly arranged circumferentially to ensure the balance of the movement. Furthermore, the top of the operating component 1 is also provided with an anti-slip protrusion to facilitate user pressing operation.

[0095] In this embodiment, the first end of the first bracket 100 is provided with a first shaft 102 extending downward in a first direction, and the first end of the second bracket 200 is provided with a sleeve 202. Both the first shaft 102 and the sleeve 202 are located within the second mounting cavity 201, and the first shaft 102 is rotatably connected to the sleeve 202, thereby enabling the first bracket 100 to rotate relative to the second bracket 200. Since the second mounting cavity 201 also houses the third connector 6 and the second connector 3, this embodiment provides connecting holes in the middle of both the third connector 6 and the second connector 3. The first shaft 102 passes through the third connector 6 and the second connector 3 in sequence and is rotatably connected to the sleeve 202. This arrangement ensures that the first shaft 102 not only guides the movement of the third connector 6 in the first direction, but also serves as the pivot of the second connector 3, guaranteeing the accuracy and stability of the rotation of the second connector 3.

[0096] The folding process of the connecting component provided in this embodiment is as follows: Press the operating member 1 to move it downward along the first direction. The operating member 1 pushes the first connecting member 2 through the first driving structure, causing the first connecting member 2 to rotate. The first locking tongue 41 is pulled back into the first locking tongue cavity 103 by the first traction cable. At the same time, the operating member 1 pushes the third connecting member 6 to move it downward along the first direction. The third connecting member 6 pushes the second connecting member 3 through the second driving structure, causing the second connecting member 3 to rotate. The second locking tongue 51 is pulled back into the second locking tongue cavity 203 by the second traction cable. When the operating member 1 fully pushes the third connecting member 6 into the first end of the second bracket 200, the first bracket 100 and the second bracket 200 are unlocked. At the same time, the first traction cable fully pulls the first locking tongue 41 into the first locking tongue cavity 103, and the first bracket 100 and the third bracket 300 are unlocked. At the same time, the second traction cable fully pulls the second locking tongue 51 into the second locking tongue cavity 203, and the second bracket 200 and the fourth bracket 400 are unlocked. Then, push the rotating connection between the first bracket 100 and the second bracket 200 inward along the second direction (perpendicular to the first direction), so that the first bracket 100 rotates around the second axis 301 and the second bracket 200 rotates around the third axis 401, and the lateral distance between the third bracket 300 and the fourth bracket 400 is reduced, thereby realizing the folding of the entire bracket.

[0097] This embodiment also provides a carrier, including the connecting component as described above. Exemplarily, the carrier is a stroller, and the connecting component is a foldable armrest, which is mounted on the stroller's frame. In this embodiment, when the stroller is folded, the foldable armrest folds simultaneously, thereby reducing the stroller's folded size and facilitating storage and carrying. Furthermore, the unlocking structure of the foldable armrest is simple, easy to operate, and has good linkage, effectively improving unlocking efficiency. It should be noted that the above-mentioned carrier is not limited to a stroller; it can also be a baby carrier, stroller, crib, children's tricycle, etc. For example, when the carrier is a crib, the connecting component is a foldable side bar on one side of the crib. In the unfolded state, it is securely locked, and unlocking via the operating component 1 is convenient and quick. After unlocking, it is easy to fold and store.
