[0094] Example 1

[0095] like Figures 1 to 4 As shown, and in combination Figure 13 This embodiment provides an unlocking mechanism for unlocking the carrier device 100 and the support device. The carrier device 100 is locked to the support device by the locking mechanism 30.

[0096] The supporting device 100 can be a baby carrier, a bassinet, a child seat, etc., and the supporting device can be the frame of a stroller, a fixed seat for fixing the supporting device 100, or a car seat, etc.

[0097] See Figure 1 , Figure 2 and Figure 3 The unlocking mechanism includes a first unlocking element 1 and a locking element 2. The first unlocking element 1 is movably disposed on the support device 100 and is used to unlock the locking mechanism 30 from locking the support device 100 and the support device. The locking element 2 is disposed between the first unlocking element 1 and the support device 100. During the process of the first unlocking element 1 unlocking the locking mechanism 30, the locking element 2 can be driven to move towards a position where the first unlocking element 1 is locked, so that after the first unlocking element 1 unlocks the locking mechanism 30, the locking element 2 locks the first unlocking element 1.

[0098] The unlocking mechanism provided in this embodiment only requires operating the first unlocking member 1 to unlock the locking mechanism 30 when disassembling the support device 100. During the process of the first unlocking member 1 unlocking the locking mechanism 30, the locking member 2 moves in the direction of locking the first unlocking member 1. After the first unlocking member 1 unlocks the locking mechanism 30, the locking member 2 locks the first unlocking member 1, keeping the locking mechanism 30 in the unlocked state. That is, after unlocking the locking mechanism 30, this unlocking mechanism can keep the locking mechanism 30 in the unlocked state, thereby keeping the support device 100 and the support device unlocked. Therefore, the user does not need to manually keep the locking mechanism 30 in the unlocked state all the time, and can remove the support from the support device with both hands or one hand, solving the problem of difficult disassembly of the existing support device 100 and support device, and improving the user experience.

[0099] Optionally, the bearing device 100 is provided with a first connecting seat 10, and the support device is provided with a second connecting seat 20. The first connecting seat 10 can cooperate with or disengage from the second connecting seat 20. When the first connecting seat 10 disengages from the second connecting seat 20, the locking member 2 releases the lock on the first unlocking member 1.

[0100] Optionally, see Figure 2 , Figure 3 and Figure 4 The unlocking mechanism also includes a second unlocking member 3 movably disposed on the first unlocking member 1. The second unlocking member 3 is used to unlock the locking member 2 from locking the first unlocking member 1. The second unlocking member 3 can release the locking member 2 from limiting the first unlocking member 1, so that both the first unlocking member 1 and the locking mechanism 30 can return to their original positions, facilitating the next locking of the bearing device 100 and the support device.

[0101] Optionally, see Figure 3 , Figure 4 and Figure 13As shown, a first connecting seat 10 is provided on the bearing device 100, and a second connecting seat 20 is provided on the support device (not shown). The first connecting seat 10 has a insertion cavity 101, and the second connecting seat 20 can be inserted into or detached from the insertion cavity 101. The locking mechanism 30 includes a locking hook 301 rotatably disposed in the insertion cavity 101, and a limit block 201 is provided on the second connecting seat 20. The locking hook 301 can hook onto the limit block 201 to lock the first connecting seat 10 and the second connecting seat 20. Figure 3 and Figure 4 As shown, after the second connecting seat 20 is inserted into the insertion cavity 101, the locking hook 301 is engaged with the limiting block 201, and the first connecting seat 10 and the second connecting seat 20 are in a locked state. At this time, the bearing device 100 is locked onto the support device. Figure 7 and Figure 8 As shown, when the first unlocking element 1 is operated to unlock the locking hook 301, the locking hook 301 disengages from the limiting block 201. At this time, the second connecting seat 20 can move out relative to the insertion cavity 101 (as shown). Figure 9 and Figure 10 (As shown), so that the bearing device 100 is disengaged from the support device. When the second connecting seat 20 is reinserted into the insertion cavity 101, the locking hook 301 can re-engage the limiting block 201, so that the second connecting seat 20 and the first connecting seat 10 are re-locked.

[0102] Further, see Figure 3 and Figure 4 The first unlocking element 1 is movably disposed in the insertion cavity 101 along the first direction, see reference. Figure 1 The first unlocking component 1 is provided with a first engaging portion 17, and the locking hook 301 is provided with a second engaging portion 303. When the first unlocking component 1 moves along a first direction, the first engaging portion 17 and the second engaging portion 303 engage to drive the locking hook 301 to rotate in the direction of disengaging from the limiting block 201. In this embodiment, the first direction is... Figure 3 and Figure 4 Pressing down on the first unlocking component 1 in the up-down direction will unlock the lock hook 301.

[0103] Specifically, see Figure 1 and Figure 4 The first mating part 17 has a first mating surface 171, and the second mating part 303 has a second mating surface 3031. When the first unlocking member 1 moves, the first mating surface 171 can slide and engage with the second mating surface 3031 to drive the locking hook 301 to rotate. Figure 1 and Figure 4As shown, when the locking hook 301 is in the locked state, the first mating part 17 does not contact the second mating part 303. During the process of driving the first unlocking member 1 to move down, after the first mating surface 171 contacts the second mating surface 3031, when the first unlocking member 1 continues to move down, the first mating surface 171 slides into contact with the second mating surface 3031. The first mating surface 171 generates a pushing force on the second mating surface 3031, thereby driving the locking hook 301 to rotate around its rotation axis.

[0104] like Figure 4 As shown, in the initial state, when the locking hook 301 is in the locked state, the second mating part 303 is located at the lower end of the first mating surface 171. During the process of pressing down the first unlocking member 1, the first mating surface 171 and the second mating surface 3031 slide into contact, and at the same time, the second mating part 303 moves upward relative to the first mating surface 171, as shown. Figure 8 As shown, after the locking hook 301 is fully unlocked, the second mating part 303 moves to the upper end of the first mating surface 171. For example, both the first mating surface 171 and the second mating surface 3031 are arc-shaped surfaces, allowing the locking hook 301 to rotate along a preset trajectory.

[0105] Further, see Figure 5 The first connecting seat 10 is provided with an opening 104 that communicates with the insertion cavity 101. The first unlocking member 1 can extend at least partially through the opening 104, which facilitates the user to operate the first unlocking member 1 to drive the lock hook 301 to unlock.

[0106] Optionally, see Figure 1 and Figure 4 An elastic piece 302 is provided on the locking hook 301. The end of the elastic piece 302 away from the locking hook 301 abuts against the inner wall of the insertion cavity 101. During the unlocking process, when the first unlocking component 1 drives the locking hook 301 to rotate and unlock, the elastic piece 302 is compressed and undergoes elastic deformation. Figure 3 The morphological changes shown are Figure 8 As shown in the diagram; when the force exerted by the first unlocking element 1 on the locking hook 301 decreases or disappears, the elastic sheet 302 releases its elastic potential energy, thereby driving the locking hook 301 to rotate in the opposite direction and return to its original position. Figure 10 The state changes shown are Figure 11 The state shown is such that the elastic piece 302 allows the locking hook 301 to automatically return to its original position, facilitating the next locking of the first connecting seat 10 and the second connecting seat 20.

[0107] Furthermore, the locking hook 301 is rotatably connected to the first connecting seat 10 via a rotating shaft. The rotating shaft can be set on the locking hook 301. A rotating hole or rotating groove is provided on the inner wall of the insertion cavity 101. The rotating shaft is inserted into the rotating hole (rotating groove) and rotates with the rotating hole (rotating groove) to realize the rotatable connection between the locking hook 301 and the first connecting seat 10.

[0108] Optionally, see Figure 3 , Figure 4 and Figure 5 The first unlocking member 1 is movably disposed on the first connecting seat 10 along a first direction. The locking member 2 includes a first locking part disposed on the first connecting seat 10 and a second locking part disposed on the first unlocking member 1. When the first unlocking member 1 moves along the first direction, the first locking part and the second locking part cooperate to lock the first unlocking member 1. That is, when the second locking part moves with the first unlocking member 1 to engage with the first locking part, the first unlocking member 1 is locked, so that the locking hook 301 of the locking mechanism 30 can be temporarily kept in the unlocked state, making it convenient to remove the supporting device 100. Furthermore, when the second unlocking member 3 moves relative to the first unlocking member 1, it can drive the first locking part to disengage from the second locking part, thereby unlocking the first unlocking member 1.

[0109] Optionally, one of the first locking part and the second locking part is a snap-fit ​​component, and the other is a limiting hole. In this embodiment, the snap-fit ​​component includes an elastic hook 21 disposed on the inner wall of the insertion cavity 101 of the first connecting seat 10, and the limiting hole includes a limiting hole 11 disposed on the first unlocking component 1. When the first unlocking component 1 moves along the first direction to the unlocking and locking mechanism 30, the elastic hook 21 hooks into the limiting hole 11 along the second direction (e.g., ...). Figure 7 As shown), to lock the first unlocking member 1, the first direction and the second direction are set at an angle. In this embodiment, the first direction is... Figure 3 and Figure 4 The top and bottom directions, the second direction is Figure 3 The left and right directions in the middle.

[0110] like Figure 3 As shown, when the first unlocking component 1 is not pressed, the elastic hook 21 is deformed by the first unlocking component 1 and is in the unlocked state. During the downward movement of the first unlocking component 1, when the limiting hole 11 moves with the first unlocking component 1 to align with the hook of the elastic hook 21, the squeezing force of the first unlocking component 1 on the elastic hook 21 disappears, and the elastic hook 21 then engages with the limiting hole 11 in the second direction under its own elastic force, thereby locking the first unlocking component 1 and keeping the lock hook 301 in the unlocked state. Figure 7 and Figure 8 As shown.

[0111] For example, the elastic hook 21 includes a connected elastic cantilever and a hook, and the side wall of the insertion cavity 101 of the first connecting seat 10 is provided with a receiving groove (such as...). Figure 5 As shown), the end of the elastic cantilever away from the hook is fixedly connected to the top wall of the receiving groove (see reference). Figure 3 and Figure 4 (in the orientation of the hook), when the hook is subjected to compressive force, the elastic cantilever undergoes elastic deformation.

[0112] Optionally, see Figure 2 and Figure 3 The second unlocking component 3 includes a triggering component 31 and an unlocking component 32. The triggering component 31 is movably disposed on the first unlocking component 1 along a first direction and has a first guide portion. The unlocking component 32 is movably disposed on the first unlocking component 1 along a second direction and has a second guide portion. When the triggering component 31 moves relative to the first unlocking component 1 along the first direction, the first guide portion and the second guide portion cooperate to drive the unlocking component 32 to move along the second direction and pass through the limiting hole 11, so that the elastic hook 21 disengages from the limiting hole 11. Since the unlocking component 32 moves with the first unlocking component 1 when the triggering component 31 moves relative to the first unlocking component 1 along the first direction, the triggering component 31 also moves relative to the unlocking component 32 along the first direction. During this process, the first guide portion and the second guide portion interact to drive the unlocking component 32 to move along the second direction, thereby driving the elastic hook 21 to disengage from the limiting hole 11 and releasing the elastic hook 21 from limiting the first unlocking component 1.

[0113] In this embodiment, see Figure 2 and Figure 7 The first guide portion has a first guide surface 311, and the second guide portion has a second guide surface 321. When the triggering component 31 moves relative to the first unlocking component 1 in a first direction, the first guide surface 311 can slide and engage with the second guide surface 321 to drive the unlocking component 32 to move in a second direction. When the triggering component moves relative to the first unlocking component 1, during the sliding engagement of the first guide surface 311 and the second guide surface 321, the first guide surface 311 can generate a pushing force on the second guide surface 321, thereby pushing the unlocking component 32 to move in the second direction, so that the unlocking component 32 pushes the elastic hook 21 to disengage from the limiting hole 11.

[0114] For example, the first guide surface 311 is an inclined surface and the second guide surface 321 is an arc surface, which can reduce the resistance of the sliding contact between the two and make the movement of the unlocking component 32 smoother. In other embodiments, both the first guide surface 311 and the second guide surface 321 can be designed as arc surfaces or inclined surfaces.

[0115] Furthermore, the second unlocking component 3 also includes a first elastic element 33 and a second elastic element 34. The first elastic element 33 extends along a first direction and is constrained between the first unlocking component 1 and the triggering component 31. The triggering component 31 can move relative to the first unlocking component 1 along the first direction under the elastic force of the first elastic element 33. The second elastic element 34 extends along a second direction and is constrained between the first unlocking component 1 and the unlocking component 32. The unlocking component 32 can move along the second direction under the elastic force of the second elastic element 34 to drive the elastic hook 21 out of the limiting hole 11. The first elastic element 33 enables the triggering component 31 to automatically move relative to the first unlocking component 1 along the first direction, thereby enabling the unlocking component 32 to automatically push the elastic hook 21 out of the limiting hole 11 under the elastic force of the second elastic element 34, thus achieving automatic unlocking.

[0116] Furthermore, the elastic force of the second elastic element 34 is less than that of the first elastic element 33. With this configuration, after the second connecting seat 20 disengages from the insertion cavity 101, the first elastic element 33 has sufficient elastic force to drive the triggering component 31 downwards, so that the second elastic element 34 drives the unlocking component 32 to insert into the limiting hole 11 and push the elastic hook 21 out of the limiting hole 11. Exemplarily, both the first elastic element 33 and the second elastic element 34 are springs.

[0117] Optionally, see Figure 2 and Figure 6 The first unlocking component 1 is provided with a first positioning post 12, and the triggering component 31 is provided with a second positioning post 312. One end of the first elastic component 33 is sleeved on the first positioning post 12, and the other end is sleeved on the second positioning post 312. This ensures that the first elastic component 33 is securely installed between the first unlocking component 1 and the triggering component 31, and ensures that the first elastic component 33 always extends and retracts in the first direction.

[0118] Further, see Figure 2 The triggering component 31 is provided with a first groove 313 extending along a first direction. The first end of the unlocking component 32 is slidably inserted into the first groove 313. The first guide surface 311 is arranged side by side with the first groove 313, so that when the triggering component 31 moves relative to the first unlocking component 1 along the first direction, the first guide surface 311 and the second guide surface 321 slide in engagement, and the unlocking component 32 moves within the first groove 313. (See reference...) Figure 1 and Figure 3 The first unlocking member 1 is provided with a first limiting groove 13 extending in the second direction. One end of the second elastic member 34 is restricted by the first limiting groove 13, and the other end of the second elastic member 34 is connected to the second end of the unlocking member 32 so that the second elastic member 34 always extends and retracts in the second direction.

[0119] Further, see Figure 2 , Figure 3 and Figure 9 The first limiting groove 13 is provided with a first protrusion 131, the second end of the unlocking component 32 is provided with a second protrusion 322, one end of the second elastic member 34 is sleeved on the first protrusion 131, and the other end of the second elastic member 34 is sleeved on the second protrusion 322, so that the second elastic member 34 is securely installed and the unlocking component 32 always moves along the second direction.

[0120] Optionally, see Figure 1 The first unlocking member 1 is provided with a stop part 18 in the part located in the insertion cavity 101. The stop part 18 and the first mating part 17 are respectively located on both sides of the first unlocking member 1. Both can stop at the edge of the opening 104 to prevent the first unlocking member 1 from disengaging from the opening 104.

[0121] Optionally, see Figure 1 and Figure 5 One of the first unlocking component 1 and the inner wall of the insertion cavity 101 is provided with a guide rail 103, and the other of the inner wall of the first unlocking component 1 and the insertion cavity 101 is provided with a second sliding groove 16. The guide rail 103 and the second sliding groove 16 slide in a first direction to guide the first unlocking component 1 to move in the first direction. The cooperation between the guide rail 103 and the second sliding groove 16 can prevent the first unlocking component 1 from moving off-center, ensuring a smoother unlocking operation.

[0122] In this embodiment, see Figure 1 The first unlocking member 1 is provided with the aforementioned second sliding groove 16, and the first connecting seat 10 is provided with a guide rail 103 extending along the first direction on the inner wall of the insertion cavity 101. Further, two second sliding grooves 16 are provided at intervals on the first unlocking member 1, and correspondingly, two guide rails 103 are provided at intervals on the inner wall of the insertion cavity 101. The two guide rails 103 and the two second sliding grooves 16 slide in a one-to-one correspondence, improving the movement stability of the first unlocking member 1 in the first direction. Exemplarily, a second sliding groove 16 is provided on both the first mating part 17 and the stop part 18. In other embodiments, guide rails 103 may also be provided on the first unlocking member 1, and second sliding grooves 16 may be provided on the inner wall of the sliding cavity 110.

[0123] Optionally, one of the triggering component 31 and the first unlocking component 1 is provided with a limiting protrusion 314, and the other of the triggering component 31 and the first unlocking component 1 is provided with a second limiting groove extending along the first direction. The limiting protrusion 314 slides in cooperation with the second limiting groove, and the second limiting groove is used to limit the movement stroke of the triggering component 31 in the first direction. In this embodiment, see reference. Figure 2The trigger component 31 is provided with the aforementioned limiting protrusion 314, and the first unlocking component 1 is provided with the aforementioned second limiting groove (not shown in the figure). The cooperation between the second limiting groove and the limiting protrusion 314 can, on the one hand, limit the movement of the trigger component 31 and prevent the trigger component 31 from disengaging from the first unlocking component 1; on the other hand, it can provide a guiding effect for the movement of the trigger component 31, ensuring smooth unlocking.

[0124] In this embodiment, see Figure 6 , Figure 7 and Figure 11 The first unlocking member 1 is provided with a sliding cavity 110 communicating with the insertion cavity 101. The triggering member 31 is slidably disposed in the sliding cavity 110 along a first direction. The second connecting seat 20 is located at one end of the insertion cavity 101 and can extend into the sliding cavity 110 and abut against the triggering member 31, so that the compression limit of the first elastic member 33 is located between the first unlocking member 1 and the triggering member 31. When the second connecting seat 20 is disengaged from the insertion cavity 101, the triggering member 31 moves relative to the first unlocking member 1 under the elastic force of the first elastic member 33.

[0125] Specifically, such as Figure 3 As shown, in the initial state, the first unlocking member 1 is not pressed down, the end of the unlocking member 32 is located in the limiting hole 11, and the lower end of the triggering member 31 is a distance away from the top of the second connecting seat 20. When the first unlocking member 1 is pressed down, the first unlocking member 1 moves the triggering member 31 and the unlocking member 32 downward together. After moving down a certain distance, the triggering member 31 abuts against the end of the second connecting seat 20. At this time, when the first unlocking member 1 is pressed down again, the triggering member 31 does not move, and the first elastic member 33 is compressed. Since the unlocking member 32 continues to move down with the first unlocking member 1, before the first unlocking member 1 moves to the first position, the first guide surface 311 of the triggering member 31 slides with the second guide surface 321 of the unlocking member 32, thereby pushing the unlocking member 32 to move to the right in the second direction (refer to...). Figure 3 and Figure 7 (position in the middle) and compress the second elastic element 34; such as Figure 7 As shown, when the first unlocking component 1 is pressed down to the position, the unlocking component 32 disengages from the limiting hole 11, and the elastic hook 21 of the locking component 2 engages with the limiting hole 11, thus locking the first unlocking component 1. During this process, the elastic plate 302 on the locking hook 301 is compressed and accumulates elastic potential energy.

[0126] like Figure 9 and Figure 10As shown, at the instant the second connecting seat 20 disengages from the insertion cavity 101, the triggering component 31 moves downward relative to the first unlocking component 1 under the elastic force of the first elastic element 33. During this process, the first guide surface 311 of the triggering component 31 slides and engages with the second guide surface 321 of the unlocking component 32. The pushing force of the first guide surface 311 on the second guide surface 321 gradually decreases. At the same time, the second elastic element 34 releases elastic potential energy to drive the unlocking component 32 to move to the left along the second direction and insert into the limiting hole 11, and push the elastic hook 21 to disengage from the limiting hole 11, thus completing the unlocking of the first unlocking component 1.

[0127] like Figure 11 and Figure 12 As shown, after the second connecting seat 20 disengages from the insertion cavity 101, the elastic plate 302 on the locking hook 301 releases elastic potential energy, causing the locking hook 301 to rotate toward the locking position. During this process, the second mating part 303 of the locking hook 301 slides into contact with the first mating part 17 of the first unlocking member 1, thereby pushing the first unlocking member 1 back to its original position along the first direction. At the same time, the first unlocking member 1 drives the triggering member 31 and the unlocking member 32 to move upward and return to their original positions.

[0128] Example 2

[0129] This embodiment provides an unlocking mechanism, which differs from Embodiment 1 in that:

[0130] Optionally, see Figure 13 , Figure 18 and Figure 19 The supporting device 100 is provided with a first connecting seat 10, and the supporting device is provided with a second connecting seat 20. The first connecting seat 10 has a insertion cavity 101, and the second connecting seat 20 can be inserted into or detached from the insertion cavity 101. The locking mechanism 30 includes a locking hook 301 rotatably disposed in the insertion cavity 101, and a limiting block 201 is provided on the second connecting seat 20. The locking hook 301 can hook and engage with the limiting block 201 to lock the first connecting seat 10 and the second connecting seat 20. Figure 18 and Figure 19 As shown, after the second connecting seat 20 is inserted into the insertion cavity 101, the locking hook 301 is engaged with the limiting block 201, and the first connecting seat 10 and the second connecting seat 20 are in a locked state. At this time, the bearing device 100 is locked onto the support device. Figure 20 and Figure 21 As shown, when the first unlocking element 1 is operated to unlock the locking hook 301, the locking hook 301 disengages from the limiting block 201. At this time, the second connecting seat 20 can move out relative to the insertion cavity 101 (as shown). Figure 22 , Figure 23 and Figure 24(As shown), so that the bearing device 100 is disengaged from the support device. When the second connecting seat 20 is reinserted into the insertion cavity 101, the locking hook 301 can re-engage the limiting block 201, so that the second connecting seat 20 and the first connecting seat 10 are re-locked.

[0131] Optionally, see Figure 18 and Figure 19 The first unlocking member 1 is movably disposed in the insertion cavity 101 along a first direction. The locking member 2 includes a first locking part disposed in the first connecting seat 10 and a second locking part disposed in the first unlocking member 1. When the first unlocking member 1 moves along the first direction, the first locking part and the second locking part cooperate to lock the first unlocking member 1. That is, when the second locking part moves with the first unlocking member 1 to engage with the first locking part, the first unlocking member 1 is locked, so that the locking hook 301 of the locking mechanism 30 can be temporarily kept in the unlocked state, making it convenient to remove the carrying device. Furthermore, when the second unlocking member 3 moves relative to the first unlocking member 1, it can drive the first locking part to disengage from the second locking part, thereby unlocking the first unlocking member 1.

[0132] Optionally, one of the first locking part and the second locking part is a snap-fit ​​member, and the other is a limiting hole. In this embodiment, see [reference needed]. Figure 18 , Figure 19 , Figure 20 and Figure 21 The latching member includes a first locking pin 22 movably disposed on the first unlocking member 1 along the second direction, and a limiting hole includes a limiting hole 102 disposed on the inner wall of the insertion cavity 101 of the first connecting seat 10. During the movement of the first unlocking member 1 along the first direction, the first locking pin 22 can be driven to insert into the limiting hole 102 along the second direction to lock the first unlocking member 1. The first direction and the second direction are set at an angle.

[0133] Furthermore, the second unlocking member 3 includes a triggering member 31 movably disposed on the first unlocking member 1 along a first direction, the triggering member 31 having a third guide portion. The second locking member is movably disposed on the first unlocking member 1 along a second direction, the second locking member having a fourth guide portion. When the triggering member 31 moves relative to the first unlocking member 1 along the first direction, the third guide portion and the fourth guide portion cooperate to drive the second locking member to engage or disengage from the first locking member along the second direction.

[0134] In this embodiment, the first direction is Figure 18 and Figure 19 The top and bottom directions, the second direction is Figure 18 The left and right directions in the middle. For example... Figure 18As shown, when the first unlocking member 1 is not pressed, the second locking part (first locking pin 22) is not engaged with the second limiting hole 102. During the downward movement of the first unlocking member 1, the first locking pin 22 moves along the second direction and inserts into the second limiting hole 102 under the interaction of the third guide part and the fourth guide part, thereby locking the first unlocking member 1 and keeping the locking hook 301 in the unlocked state, as shown. Figure 20 and Figure 21 As shown.

[0135] When the first unlocking component 1 remains stationary while the triggering component 31 moves relative to the first unlocking component 1 along the first direction, the triggering component 31 also moves relative to the first locking pin 22 along the first direction. During this process, the interaction between the third guide portion and the fourth guide portion drives the first locking pin 22 to move along the second direction, thereby causing the first locking pin to disengage from the limiting hole 102 and unlocking the first unlocking component 1. Figure 22 As shown.

[0136] Further, see Figure 15 and Figure 18 The first unlocking component 1 is provided with a limiting hole 4 19, and the first locking pin 22 is restricted by the limiting hole 4 19 in the first direction and can pass through the limiting hole 4 19 and engage with the limiting hole 2 102. Figure 18 As shown, when the first unlocking member 1 is not pressed, the locking hook 301 is in a locked state, and the end of the first locking pin 22 is engaged in the limiting hole 4 19 to prevent the first locking pin 22 from shifting relative to the first unlocking member 1 in the first direction. Figure 15 and Figure 20 As shown, after the first unlocking member 1 is pressed and moved into place, the end of the first locking pin 22 passes through the limiting hole 19 and is engaged in the limiting hole 102 to restrict the first unlocking member 1 from moving in the first direction, thereby keeping the locking hook 301 in the unlocked state.

[0137] Optionally, see Figure 14 and Figure 19 The third guide portion has a third guide surface 315, and the fourth guide portion has a fourth guide surface 221. The third guide surface 315 can slide with the fourth guide surface 221 to drive the first locking pin 22 to move in the second direction. When the first unlocking member 1 and the triggering member 31 move relative to each other in the first direction, the third guide surface 315 slides with the fourth guide surface 221, and the third guide surface 315 can generate a pushing force on the fourth guide surface 221, thereby driving the first locking pin 22 to move in the second direction.

[0138] Furthermore, the third guide surface 315 includes a first positioning plane 3151, a guide ramp 3152, and a second positioning plane 3153 connected in sequence. The first positioning plane 3151 is further away from the first locking part (limiting hole 102) relative to the second positioning plane 3153. When the second locking part cooperates with the first locking part (the first locking pin 22 is inserted into the limiting hole 102), the fourth guide surface 221 abuts against the second positioning plane 3153. Figure 18 As shown, in the initial state, the fourth guide surface 221 of the first locking pin 22 abuts against the first positioning plane 3151, so that the end face of the first locking pin 22 does not protrude from the limiting hole 19. During the pressing down of the first unlocking member 1, the triggering member 31 moves a certain distance with the first unlocking member 1. When the triggering member 31 abuts against the second connecting seat 20, the triggering member 31 remains stationary, and relative movement occurs between it and the first unlocking member 1. The fourth guide surface 221 of the first locking pin 22 slides from the first positioning plane 3151 to the guide slope 3152, and then slides from the guide slope 3152 to the second positioning plane 3153, as shown. Figure 20 As shown, at this time, the first locking pin 22 passes through the limiting hole 4 19 along the second direction and is engaged in the limiting hole 2 102, thus completing the locking of the first unlocking component 1.

[0139] Furthermore, the fourth guide surface 221 is an arc surface, which can reduce the resistance of the sliding contact between the fourth guide surface 221 and the third guide surface 315, making the first locking pin 22 move more smoothly.

[0140] Optionally, see Figure 16 , Figure 17 and Figure 18 The second unlocking member 3 further includes a first elastic member 33, which extends along a first direction and is compressed and limited between the first unlocking member 1 and the trigger member 31. The trigger member 31 can move relative to the first unlocking member 1 along the first direction under the elastic force of the first elastic member 33. The second unlocking member 3 also includes a second elastic member 34, which extends along a second direction and is compressed and limited between the second locking part (first locking pin 22) and the first unlocking member 1. The second locking part can move along the second direction under the elastic force of the second elastic member 34 to cooperate with the first locking part. The first elastic member 33 enables the trigger member 31 to automatically move relative to the first unlocking member 1 along the first direction, thereby enabling the first locking pin 22 to automatically insert into or disengage from the limiting hole 102 under the elastic force of the second elastic member 34, thus realizing the automatic unlocking of the first unlocking member 1.

[0141] Furthermore, the elastic force of the second elastic element 34 is less than that of the first elastic element 33. With this configuration, after the second connecting seat 20 disengages from the insertion cavity 101, the first elastic element 33 has sufficient elastic force to drive the trigger component 31 downwards, thereby driving the first locking pin 22 to disengage from the limiting hole 102. For example, both the first elastic element 33 and the second elastic element 34 are springs.

[0142] Optionally, the first unlocking component 1 is provided with a first positioning post (not shown in the figure), see reference. Figure 16 The triggering component 31 is provided with a second positioning post 312. One end of the first elastic member 33 is sleeved on the first positioning post, and the other end is sleeved on the second positioning post 312. This ensures that the first elastic member 33 is securely installed between the first unlocking component 1 and the triggering component 31, guaranteeing that the first elastic member 33 always extends and retracts in the first direction.

[0143] Further, see Figure 16 and Figure 17 The triggering component 31 is provided with a first groove 313 extending along a first direction. The first end of the second locking part (first locking pin 22) is slidably inserted into the first groove 313. The third guide surface 315 is arranged side by side with the first groove 313, so that when the triggering component 31 moves relative to the first unlocking component 1 along the first direction, the third guide surface 315 slides and engages with the fourth guide surface 221, while the first locking pin 22 moves within the first groove 313. (See reference...) Figure 14 and Figure 20 The first unlocking member 1 is provided with a first limiting groove 13 extending in the second direction. One end of the second elastic member 34 is restricted by the first limiting groove 13, and the other end of the second elastic member 34 is connected to the second end of the first locking pin 22 so that the second elastic member 34 always extends and retracts in the second direction.

[0144] Further, see Figure 16 , Figure 17 and Figure 20 The first limiting groove 13 is provided with a first protrusion 131, the second end of the first locking pin 22 is provided with a fourth protrusion 222, one end of the second elastic member 34 is sleeved on the first protrusion 131, and the other end of the second elastic member 34 is sleeved on the fourth protrusion 222, so that the second elastic member 34 is securely installed and the first locking pin 22 always moves along the second direction.

[0145] Optionally, one of the triggering component 31 and the first unlocking component 1 is provided with a limiting protrusion 314, and the other of the triggering component 31 and the first unlocking component 1 is provided with a second limiting groove 14 extending along the first direction. The limiting protrusion 314 slides in engagement with the second limiting groove 14, and the second limiting groove 14 is used to limit the movement stroke of the triggering component 31 in the first direction. In this embodiment, see reference. Figure 15 and Figure 17The trigger component 31 is provided with the aforementioned limiting protrusion 314, and the first unlocking component 1 is provided with the aforementioned second limiting groove 14. The cooperation between the second limiting groove 14 and the limiting protrusion 314 can, on the one hand, limit the movement stroke of the trigger component 31 and prevent the trigger component 31 from disengaging from the first unlocking component 1; on the other hand, it can provide a guiding effect on the movement of the trigger component 31 and prevent the trigger component 31 from moving off-center.

[0146] In this embodiment, see Figure 20 and Figure 22 The first unlocking member 1 is provided with a sliding cavity 110 communicating with the insertion cavity 101. The triggering member 31 is slidably disposed in the sliding cavity 110 along a first direction. The second connecting seat 20 is located at one end of the insertion cavity 101 and can extend into the sliding cavity 110 and abut against the triggering member 31, so that the compression limit of the first elastic member 33 is located between the first unlocking member 1 and the triggering member 31. When the second connecting seat 20 is disengaged from the insertion cavity 101, the triggering member 31 moves relative to the first unlocking member 1 under the elastic force of the first elastic member 33.

[0147] Specifically, such as Figure 18 As shown, in the initial state, the first unlocking component 1 is not pressed, the end of the first locking pin 22 is located in the limiting hole 4 19, and there is a small distance between the lower end of the trigger component 31 and the top end of the second connecting seat 20. When the first unlocking component 1 is pressed down, the first unlocking component 1 moves the trigger component 31 down together with the first elastic element 33, and the first locking pin 22 moves down with the first unlocking component 1 at the same time. After moving down a short distance, the lower end of the trigger component 31 abuts against the top end of the second connecting seat 20. When the first unlocking component 1 is pressed down again, the trigger component 31 does not move, and the first elastic element 33 is compressed. During this process, the third guide surface 315 of the trigger component 31 always slides with the fourth guide surface 221 of the first locking pin 22. Since the second positioning plane 3153 of the third guide surface 315 is closer to the limiting hole 102 than the first positioning plane 3151, the first locking pin 22 moves to the left in the second direction under the elastic force of the second elastic element 34 as the first unlocking component 1 moves down (refer to...). Figure 18 and Figure 20 (in the orientation), until the first locking pin 22 is inserted into the limiting hole 102, as shown. Figure 20 As shown, locking the first unlocking component 1 is complete. Figure 19 and Figure 21 As shown, during this process, the elastic sheet 302 on the locking hook 301 is compressed and accumulates elastic potential energy.

[0148] like Figure 22 and Figure 22As shown, at the instant the second connecting seat 20 disengages from the insertion cavity 101, the triggering component 31 moves downward relative to the first unlocking component 1 under the elastic force of the first elastic element 33. During this process, the fourth guide surface 221 of the first locking pin 22 slides from the second positioning plane 3153 to the guide slope 3152, and then slides from the guide slope 3152 to the first positioning plane 3151. The second elastic element 34 is deformed by pressure, and the first locking pin 22 moves to the right along the second direction and disengages from the limiting hole 102, thus completing the unlocking of the first unlocking component 1.

[0149] like Figure 23 and Figure 24 As shown, after the second connecting seat 20 disengages from the insertion cavity 101, the elastic plate 302 on the locking hook 301 releases elastic potential energy, causing the locking hook 301 to rotate toward the locking position. During this process, the second mating part 303 of the locking hook 301 slides into the first mating part 17 of the first unlocking member 1, thereby pushing the first unlocking member 1 back to its original position along the first direction. At the same time, the first unlocking member 1 drives the triggering member 31 and the first locking pin 22 to move upward and return to their original positions.

[0150] Example 3

[0151] like Figures 25 to 27 As shown, this embodiment provides an unlocking mechanism, which differs from Embodiments 1 and 2 in that:

[0152] Optionally, see Figure 25 and Figure 26 The first unlocking component 1 is connected to the locking hook 301, and the first unlocking component 1 can swing left and right relative to the first connecting seat 10 (see reference). Figure 25 and Figure 26 (In the orientation of the middle), the user only needs to move the first unlocking component 1 to drive the lock hook 301 to unlock. Further, the first connecting seat 10 is provided with a plug cavity 101, the second connecting seat 20 can be inserted into or detached from the plug cavity 101, and the lock hook 301 is rotatably disposed in the plug cavity 101.

[0153] Optionally, one of the first locking part and the second locking part is a snap-fit ​​member, and the other is a limiting hole. In this embodiment, see [reference needed]. Figure 25 and Figure 26 The locking component includes a second locking pin 24 movably disposed on the first unlocking component 1, and a limiting hole includes a limiting hole three 105 disposed on the first connecting seat 10. During the process of the first unlocking component 1 moving toward the unlocking and locking mechanism 30, the second locking pin 24 can be locked into the limiting hole three 105.

[0154] like Figure 25 and Figure 26 As shown, when the locking hook 301 is in the locked state, the second locking pin 24 is not engaged with the limiting hole 3 105, and the first unlocking part 1 is facing towards Figure 26During the movement in the direction indicated by the arc-shaped arrow, when the second locking pin 24 moves with the first unlocking component 1 to align with the limiting hole 3 105, the second locking pin 24 engages with the limiting hole 3 105, thereby locking the first unlocking component 1. Figure 26 As shown.

[0155] Furthermore, the locking element 2 also includes a fifth elastic element 25, one end of which is connected to the second locking pin 24, and the other end of which is connected to the first unlocking element 1, as shown below. Figure 25 As shown, when the locking hook 301 is in the locked state, the end of the second locking pin 24 abuts against the first connecting seat 10, and the fifth elastic member 25 is in a compressed state. When the first unlocking member 1 moves the second locking pin 24 to align with the limiting hole 3 105, the fifth elastic member 25 releases its elastic potential energy to drive the second locking pin 24 into the limiting hole 3 105. Under the elastic force of the fifth elastic member 25, the second locking pin 24 is stably held in the position of locking the first unlocking member 1, so that the locking hook 301 is temporarily kept in the unlocked position.

[0156] Furthermore, the end of the second locking pin 24 is designed as an arc surface to ensure that the second locking pin 24 can smoothly engage or disengage from the limiting hole 3 105.

[0157] Optionally, see Figure 25 and Figure 26 An elastic reset member 304 is provided between the locking hook 301 and the inner wall of the insertion cavity 101. The locking hook 301 can rotate towards the hook-locking block 201 under the elastic force of the elastic reset member 304. During the unlocking process where the first unlocking member 1 drives the locking hook 301 to rotate and unlock, the elastic reset member 304 is stretched. When the second connecting seat 20 disengages from the insertion cavity 101 and releases the first unlocking member 1, the elastic reset member 304 releases its elastic potential energy, causing the locking hook 301 to rotate and reset towards the hook-locking block 201.

[0158] Optionally, see Figure 26 and Figure 27 The unlocking mechanism also includes a second unlocking member 3 disposed on the second connecting seat 20. The second unlocking member 3 includes a fourth unlocking member 37 disposed on the second connecting seat 20. During the process of the second connecting seat 20 disengaging from the first connecting seat 10, the fourth unlocking member 37 can drive the locking hook 301 to move toward the locking position, so that the locking hook 301 drives the first unlocking member 1 and the second locking pin 24 to disengage from the limiting hole 3 105, thereby unlocking the first unlocking member 1.

[0159] Example 4

[0160] like Figures 28 to 33 As shown, this embodiment provides an unlocking mechanism, which differs from Embodiments 1, 2, and 3 in that:

[0161] Optionally, one of the first locking part and the second locking part is a snap-fit ​​member, and the other is a limiting hole. In this embodiment, see [reference needed]. Figure 28 , Figure 29 , Figure 30 and Figure 31 The locking component includes a second locking pin 24 movably disposed on the first unlocking component 1, and a limiting hole includes a limiting hole three 105 disposed on the first connecting seat 10. During the process of the first unlocking component 1 moving toward the unlocking and locking mechanism 30, the second locking pin 24 can be locked into the limiting hole three 105.

[0162] like Figure 28 and Figure 29 As shown, when the locking hook 301 is in the locked state, the second locking pin 24 is not engaged with the limiting hole 3 105. During the downward movement of the first unlocking member 1, when the second locking pin 24 moves with the first unlocking member 1 to align with the limiting hole 3 105, the second locking pin 24 engages with the limiting hole 3 105, thereby locking the first unlocking member 1. Figure 30 and Figure 31 As shown.

[0163] Furthermore, the locking member 2 also includes a swing member 26 and a fifth elastic member 25. The swing member 26 is rotatably connected to the first unlocking member 1. The second locking pin 24 is a protrusion protruding from the swing member 26. One end of the fifth elastic member 25 is connected to the swing member 26, and the other end of the fifth elastic member 25 is connected to the first unlocking member 1. Figure 28 As shown, when the locking hook 301 is in the locked state, the end of the second locking pin 24 abuts against the first connecting seat 10, and the fifth elastic member 25 is in a compressed state. When the first unlocking member 1 moves the second locking pin 24 to align with the limiting hole 3 105, the fifth elastic member 25 releases its elastic potential energy, causing the swing member 26 to rotate at a certain angle, thereby driving the second locking pin 24 to engage in the limiting hole 3 105, as shown. Figure 30 As shown, the second locking pin 24 is stably held in the position of locking the first unlocking member 1 under the elastic force of the fifth elastic member 25, so that the locking hook 301 is temporarily kept in the unlocked position.

[0164] Further, see Figure 30 , Figure 32 and Figure 33 The unlocking mechanism also includes a second unlocking member 3 disposed on the second connecting seat 20. The second unlocking member 3 includes a fifth unlocking member 38 disposed on the second connecting seat 20. During the process of the second connecting seat 20 disengaging from the insertion cavity 101 of the first connecting seat 10, the fifth unlocking member 38 can drive the swing member 26 to rotate, so that the swing member 26 drives the second locking pin 24 to disengage from the limiting hole 3 105 (e.g., Figure 32 As shown), the first unlocking component 1 is unlocked.

[0165] Example 5

[0166] This embodiment provides a carrying device, including the unlocking mechanism described in any of the previous embodiments. The carrying device can be a baby carrier, a bassinet, a child seat, etc.

[0167] This embodiment also provides a carrier, including a support device and an unlocking mechanism as described above. The carrier 100 is detachably mounted to the support device and locked to the support device by a locking mechanism 30. The unlocking mechanism is used to unlock the locking mechanism 30. The carrier can be a baby carrier, bassinet, child seat, etc. The support device can be the frame of a stroller or trailer, a fixed seat for fixing the carrier, or a car seat, etc.

[0168] Optionally, the supporting device 100 is provided with first connecting seats 10 on at least two opposite sides, and the supporting device is provided with second connecting seats 20 corresponding to at least two of the first connecting seats 10. A locking member 2 and a second unlocking member 3 are provided between at least one first connecting seat 10 and its corresponding first unlocking member 1. The locking member 2 is used to lock the first unlocking member 1, so that the locking mechanism 30 remains in the unlocked state, and the second unlocking member 3 is used to unlock the first unlocking member 1.

[0169] That is, locking members 2 can be provided between the first connecting seats 10 and the first unlocking member 1 on both sides of the carrying device 100, so that both sides of the carrying device 100 can be kept in the unlocked state at the same time, making it easier to remove the carrying device. Of course, locking members 2 can also be provided only between the first connecting seat 10 and the first unlocking member 1 on one side of the carrying device 100. When the locking mechanism 30 on one side of the carrying device 100 is unlocked, the other side of the carrying device 100 is still in the locked state, so that the carrying device 100 (such as a basket) is not easy to fall off the support device (such as a frame), which can improve the safety of the vehicle.

[0170] The vehicle using this unlocking mechanism can keep the locking mechanism 30 unlocked after the unlocking mechanism unlocks the locking mechanism 30, thereby keeping the carrier 100 and the support device unlocked. Therefore, the user does not need to manually keep the locking mechanism 30 unlocked all the time, and can remove the carrier from the support device with one hand or free both hands. This solves the problem of the difficulty in disassembling the existing carrier 100 and support device, and improves the user experience.

[0171] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
