Description

[0003] The folding structure of the folding baby carriers on the market is becoming more and more complex. For example, the prior art (CN116570127A) discloses a folding baby carrier, which includes an upper rail support, a lower rail support, and a folding device arranged between the two. The folding device realizes the unfolding and folding of the carrier body by setting a first unlocking driving assembly, a locking device driven by a steel wire, a folding joint, and a first linkage assembly composed of multiple connecting rods. Specifically, after the user presses the unlocking button, the power is transmitted to the locking piece through the steel wire, which releases the locking of the folding joint. Then the user needs to press the upper rail support to make it move down, and finally realizes the folding by using the complex linkage of the multi-link mechanism. Although this scheme realizes the overall folding, the transmission link is too long, the structure is complex, and there are too many parts, which leads to high production cost. Moreover, in the long-term use process, the risk of failure of multiple hinge points and transmission links is relatively increased, and the operation process is not simple and intuitive enough.

Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. In order to make the above objectives, characteristics and advantages of the present application more apparent, a lot of specific details are described in the following description so as to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] Referring to Figures 1-12 An infant carrier includes a frame 100 switchable between a folded state and an unfolded state, the frame 100 comprising: a fixed rod assembly 1, an upper portion of which is used to movably connect with a first support assembly 2, and a lower portion of which is used to movably connect with a second support assembly 3; a connecting rod assembly 4, which is used to synchronously connect the fixed rod assembly 1, the first support assembly 2 and the second support assembly 3; a locking mechanism 5, which is arranged on a connecting and matching position between the fixed rod assembly 1 and the first support assembly 2, and which locks the first support assembly 2 on the fixed rod assembly 1 in the unfolded state of the frame 100; an unlocking mechanism 6, which is movably arranged on the first support assembly 2 and is in transmission connection with one end of the locking mechanism 5; when the frame 100 is switched from the unfolded state to the folded state, the unlocking mechanism 6 drives the locking mechanism 5 to release the locking of the first support assembly 2, and the first support assembly 2 drives the second support assembly 3 to synchronously move on the fixed rod assembly 1 through the connecting rod assembly 4, and each support assembly is folded along the center position of the fixed rod assembly 1.

[0032] The connecting rod assembly 4 is used to synchronously connect the fixed rod assembly 1, the first support assembly 2 and the second support assembly 3, so that the complex steel cable transmission and the multi-connecting rod linkage structure in the prior art are omitted, the number of parts is reduced, and the synchronous linkage between the first support assembly 2 and the second support assembly 3 is realized through the connecting rod assembly 4; When unfolded, the first support assembly 2 and the second support assembly 3 are unfolded in a direction away from the center of the fixed rod assembly 1, and the linkage assembly 4 is unfolded synchronously, when the frame body 100 reaches the unfolded state, the locking mechanism 5 locks the first support assembly 2 on the fixed rod assembly 1, at this time, the linkage assembly 4 keeps the positions of the assemblies stable, the frame body 100 maintains the unfolded form and cannot be folded at will, realizing one-key unlocking and synchronous folding of the baby basket. When folding, the unlocking mechanism 6 is operated to drive the locking mechanism 5 to release the locking of the first support assembly 2; when the user moves the first support assembly 2 towards the center of the fixed rod assembly 1, the first support assembly 2 drives the second support assembly 2 to move synchronously through the linkage assembly 4, and finally each support assembly is folded along the center of the fixed rod assembly, and the folding is completed.

[0033] In the embodiment, the first support assembly 2 and the second support assembly 3 are respectively provided with two groups, and the first support assembly 2 is located above the second support assembly 3, the two groups of first support assemblies 2 are arranged in a left-right interval, and the two groups of second support assemblies 3 are arranged in a left-right interval, and each support assembly is connected with the linkage assembly 4.

[0034] Referring to Figure 3 and Figure 4 , the locking mechanism 5 includes a locking piece 501 connected with the first support assembly 2, the locking piece 501 is arranged in an axial reciprocating manner between the first support assembly 2 and the fixed rod assembly 1 at a locking position and an unlocking position, and the driving end of the unlocking mechanism 6 is drivingly connected with the locking piece 501.

[0035] The locking piece 501 realizes locking and unlocking through axial reciprocating movement, which is simple in structure, more direct in transmission, smoother in locking and unlocking actions, and reduces fault points compared with existing complex transmission; the unlocking mechanism 6 directly drives the axial movement of the locking piece 501, which simplifies the operation steps, enables the user to quickly complete the unlocking, and improves the operation experience.

[0036] When the frame body 100 is unfolded, the unlocking mechanism 6 pushes the locking piece 501 to move along the axis to the locking position, when the locking piece 501 reaches the locking position, the first support assembly 2 is locked on the fixed rod assembly 1, and the frame body 100 remains unfolded. When the unlocking mechanism 6 is operated, the driving end drives the locking piece 501 to move along the axis to the unlocking position, when the locking piece 501 reaches the unlocking position, the locking of the first support assembly 2 on the fixed rod assembly 1 is released, and the subsequent folding action can be performed.

[0037] The fixed rod assembly 1 is provided with a sliding piece 7, and the locking piece 501 is limitingly and rotatably connected with the sliding piece 7; the sliding piece 7 and the first supporting assembly 2 are locked on the fixed rod assembly 1 synchronously by the locking piece 501 in the unfolded state of the frame body 100; when the locking piece 501 is driven to the unlocking position by the unlocking mechanism 6, the first supporting assembly 2 is rotated on the sliding piece 7 through the locking piece 501, and the first supporting assembly 2 and the locking piece 501 are synchronously slid on the fixed rod assembly 1 through the sliding piece 7.

[0038] The sliding piece 7 realizes the limit rotation and synchronous sliding of the locking piece 501 and the first supporting assembly 2, so that the first supporting assembly 2 has both rotation and sliding actions, and the motion trajectory is optimized; the rotation of the first supporting assembly 2 and the sliding of the sliding piece 7 are realized synchronously through the above structure, so as to prepare for subsequent folding, and the folding is more compact; when unfolded, the locking piece 501 synchronously locks the sliding piece 7 and the first supporting assembly 2; in the locked state, the first supporting assembly 2 cannot drive the sliding piece 7 to slide when forcibly rotated, so that effective locking is realized, and the baby basket cannot be folded randomly after being unfolded. The locking piece 501 is in the locked position, and the sliding piece 7 and the first supporting assembly 2 are synchronously locked on the fixed rod assembly 1, so as to ensure the stable unfolding of the frame body 100. When folded, the unlocking mechanism 6 drives the locking piece 501 to the unlocking position, and the locking piece 501 of the first supporting assembly 2 is rotated on the sliding piece 7, and simultaneously drives the sliding piece 7 to slide along the fixed rod assembly 1 in the folding process.

[0039] The locking mechanism 5 further comprises a locking pin 502 arranged on the locking piece 501, and the sliding piece 7 is provided with a first arc-shaped groove 701 matched with the rotation track of the first supporting assembly 2; the locking pin 502 is limitingly and movably arranged on the first arc-shaped groove 701 when the first supporting assembly 2 is rotated; When the frame body 100 is in the unfolded state, and the locking piece 501 is in the locked position, the locking pin 502 is inserted into the first arc-shaped groove 701 of the sliding piece 7 and the fixed rod assembly 1, so as to realize locking; the locking pin 502 cooperates with the first arc-shaped groove 701 to realize double locking of the sliding piece 7 and the fixed rod assembly 1 by the locking piece 501 during unfolding, so as to improve the locking reliability and prevent the frame body 100 from being folded accidentally; and the locking pin 502 limits the first supporting assembly 2 when the first supporting assembly 2 is rotated, so as to ensure the stability of the rotation track, avoid motion jamming or deviation, and improve the use safety and smoothness.

[0040] Referring to Figure 5 and Figure 8The fixed rod assembly 1 comprises a vertical rod 101, a sliding piece 7 sleeved on the periphery of the vertical rod 101, a first locking hole 102 provided on the vertical rod 101 and matched with the locking piece 501, and an anti-falling limiting piece 8 provided on the vertical rod 101 and inserted into the vertical rod 101 to limit the sliding piece 7. The sliding piece 7 is limited between the anti-falling limiting piece 8 and the connecting rod assembly 4 when sliding. The anti-falling limiting piece 8 is provided with a second locking hole 801 which is correspondingly arranged with the first locking hole 102.

[0041] The sliding piece 7 is sleeved on the periphery of the vertical rod 101, and the cross sections of the sliding piece 7 and the vertical rod 101 are non-circular, so that relative rotation between the two is prevented, linear sliding of the sliding piece 7 on the vertical rod 101 is ensured, and friction failure is reduced. The anti-falling limiting piece 8 prevents the sliding piece 7 from falling off the vertical rod 101 during sliding, and improves structural safety. The first locking hole 102 is correspondingly arranged with the second locking hole 801, so that the locking piece 501 can act on the vertical rod 101 and the anti-falling limiting piece 8 at the same time when locking, the locking is more firm, and accidental movement of the sliding piece 7 in the unfolded state is avoided.

[0042] The vertical rod 101 is in a hollow state, the sliding piece 7 is provided with a cavity inserted into the vertical rod 101, and the anti-falling limiting piece 8 is inserted into the middle structure of the vertical rod 101. The anti-falling limiting piece 8 limits the sliding piece 7 at the top, preventing the sliding piece 7 from separating outward from the vertical rod 101. When the sliding piece 7 slides along the vertical rod 101 to the unfolded position, the locking piece 501 is inserted into the first locking hole 102 and the second locking hole 801 to lock the sliding piece 7, and the anti-falling limiting piece 8 limits the sliding piece 7 from separating upward from the vertical rod 101. After the locking piece 501 is unlocked, the sliding piece 7 slides along the vertical rod 101 and is limited by the anti-falling limiting piece 8 and the connecting rod assembly 4, and only slides within a limited range, preventing falling off and ensuring safety during folding and unfolding.

The locking pin 502 is eccentrically arranged on the locking piece 501 and inserted into the connecting hole 203 of the first connecting piece 202, so that when the locking piece 501 rotates, the first connecting piece 202 can be driven to rotate synchronously through the eccentric locking pin 502. The transmission is direct, no additional transmission components are needed, the structure is simplified, the risk of failure is reduced, the operation is more labor-saving, the rotating and locking structures are integrally arranged on the locking piece 501, and the structure is simplified.
