Description

Technical Field

[0001] This utility model relates to the technical field of unlocking and folding vehicle frames, specifically to a vehicle frame and its infant carrier. Background Technology

[0002] In the stroller industry, foldable stroller frames have become the mainstream design for easy storage and transportation. In existing technologies, the folding operation experience and safety of stroller frames are important areas for improvement. Currently, most stroller frames on the market fold their handle assembly through a single operation. For example, in the solution disclosed in Chinese invention patent CN118163850A, the user can unlock the handle locking mechanism by pressing an operating component, and then rotate the handle to fold it. While this "one-click unlocking" solution is straightforward, it also presents a potential risk: because the core locking mechanism can be unlocked in one step, if the user accidentally touches the unlock button, the handle assembly may accidentally unlock and fold, posing a safety hazard.

[0003] Therefore, there is a lack of a stroller frame unlocking and folding solution in the existing technology that can effectively prevent single-step misoperation from the mechanical structure and requires the user to intentionally perform multiple orderly steps to complete the folding, thereby improving safety.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a frame and its baby carrier to overcome the shortcomings of the prior art. By providing a release mechanism with a linkage locking mechanism, the release mechanism releases the locking mechanism through two different and orderly operations of the first unlocking member and the second unlocking member, realizing two-step unlocking and folding.

The release mechanism is configured to release the locking mechanism through at least two different and orderly operations, realizing a two-step unlocking and folding between the handle assembly and the frame, so that the unfolded handle assembly can be rotated and folded. The unlocking mechanism includes a first unlocking component and a second unlocking component that operate in a predetermined sequence.

[0007] The handle assembly has a telescopic adjustment state and is provided with an interlocking mechanism that locks it in a pending state; the first unlocking member and the second unlocking member are respectively connected to the interlocking mechanism in a transmission connection, and one end of the interlocking mechanism is used to engage the locking mechanism. The first unlocking component is used to unlock the interlocking mechanism, so that the handle assembly drives the interlocking mechanism to move away from or towards the locking mechanism during the extension and retraction process; When the interlocking mechanism and the locking mechanism are engaged, the second unlocking component drives the locking mechanism to unlock through the interlocking mechanism.

[0008] The handle assembly includes a fixed frame and a handle, a first unlocking component and a second unlocking component are disposed on the handle, the fixed frame is rotatably connected to the frame body, and the handle extends and retracts on the fixed frame; The interlocking mechanism is located inside the handle and includes a first locking block, a fastening element, and a base.

The first locking block is used to lock the extension and retraction of the handle assembly and is connected in a transmission manner to the first unlocking component; The fastening element is used to fasten the locking mechanism and is connected to the second unlocking element in a transmission manner.

[0009] The locking mechanism includes a locking spring. When the handle assembly is in the extended state or in a telescopic motion, the locking mechanism is elastically locked in the relative rotational position between the handle assembly and the frame by the locking spring.

[0010] The locking mechanism also includes a second locking block. The frame is provided with a frame joint having a lock hole, and the fixed frame is provided with a handle joint.

The movable block and the first locking block move in different directions. The fastening element is elastically rotatably connected to the base and the movable block respectively. One end of the fastening element extends toward the first locking block. The fastening element is engaged or disengaged from the second locking block by rotation.

[0013] The first unlocking component and the second unlocking component are respectively connected to the first locking block and the movable block via transmission components; When the first unlocking component is operated, it drives the first locking block to move through the transmission component and triggers the fastening component to rotate. The second unlocking component is connected to the second unlocking component via a movable block.

[0014] The fixing frame is provided with a number of locking slots arranged in a linear manner. When the handle is fixed on the fixing frame, the first locking block is locked in the corresponding locking slot.

[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] See Figures 1-9 A frame, comprising: The frame 100 is capable of being unfolded or folded. A handle assembly 1 is provided, which can be rotated and unfolded or folded relative to the frame 100; a locking mechanism 2 is provided between the handle assembly 1 and the frame 100 to lock their relative rotational position. The release mechanism is used to work in conjunction with the locking mechanism 2 and is set on the handle assembly 1. The release mechanism is configured to release the locking mechanism 2 by at least two different and orderly operations, so as to realize the two-step unlocking and folding between the handle assembly 1 and the frame 100, so that the unfolded handle assembly 1 can be rotated and folded. Furthermore, the unlocking mechanism includes a first unlocking component 3 and a second unlocking component 4 that operate in a predetermined sequence.

[0030] The unlocking mechanism releases the locking mechanism 2 through two different, sequential operations of the first unlocking component 3 and the second unlocking component 4, achieving two-step unlocking and folding. This design effectively prevents accidental unlocking in a single step through its mechanical structure. Users must intentionally execute a sequence of steps to complete the unlocking and folding process, thus resolving the safety hazard of accidental folding caused by unintentional touches in existing one-button unlocking systems.

[0031] Furthermore, the handle assembly 1 has a telescopic adjustment state and is provided with an interlocking mechanism 5 that locks it in a pending state; the first unlocking member 3 and the second unlocking member 4 are respectively connected to the interlocking mechanism 5 in a transmission manner, and one end of the interlocking mechanism 5 is used to engage the locking mechanism 2. The first unlocking component 3 is used to unlock the interlocking mechanism 5, so that the handle assembly 1 drives the interlocking mechanism 5 to move away from or towards the locking mechanism 2 during the extension and retraction process; Furthermore, when the interlocking mechanism 5 and the locking mechanism 2 are engaged, the second unlocking component 4 drives the locking mechanism 2 to unlock through the interlocking mechanism 5.

[0032] The unlocking mechanism is integrated into the handle 102, conforming to user habits. The interlocking mechanism 5 is also integrated into the handle 102, resulting in a compact structure that does not take up extra space. When unlocking is required, the handle assembly 1 must first be extended or retracted. This extension or retraction requires the operation of the first unlocking component 3. The mechanical structure effectively prevents accidental unlocking in one step. The user must intentionally extend or retract the handle assembly 1, causing the interlocking mechanism 5 to follow the extension or retraction of the handle assembly 1 to the position where it engages the locking mechanism 2. Only then can the locking mechanism 2 be operated by the second unlocking component 4 to complete the unlocking and folding process. This solves the safety hazard of accidental folding caused by unintentional touches in existing one-button unlocking systems.

[0033] Furthermore, the handle assembly 1 includes a fixing frame 101 and a handle 102, a first unlocking member 3 and a second unlocking member 4 are disposed on the handle 102, the fixing frame 101 is rotatably connected to the frame 100, and the handle 102 is telescopically movable on the fixing frame 101. Furthermore, the interlocking mechanism 5 is disposed inside the handle 102 and includes a first locking block 501, a fastening member 502 and a base 503. The first locking block 501 and the fastening member 502 are elastically and movably disposed on the base 503, and the base 503 is fixedly connected to the handle 102. The first locking block 501 is used to lock the extension and retraction of the handle assembly 1 and is connected to the first unlocking member 3 in a transmission manner; The fastening member 502 is used to fasten the locking mechanism 2 and is connected to the second unlocking member 4 in a transmission manner.

[0034] Furthermore, the first locking block 501 and the fastening member 502 are elastically movable, which is conducive to the elastic reset between the first locking block 501 and the fastening member 502. One end of the fastening member 502 extends toward the first locking block 501. When the first locking block 501 moves, it will act on the fastening member 502, causing the fastening member 502 to disengage from or engage with the locking mechanism 2. When the fastening member 502 disengages from the locking mechanism 2, the handle assembly 1 can adjust its extension length according to the user's needs in normal use. When the handle assembly 1 needs to be folded, the handle assembly 1 extends and retracts to the set position, so that the fastening member 502 engages with the locking mechanism 2.

[0035] The locking mechanism 2 includes a locking spring 202. When the handle assembly 1 is in the extended state or in the process of telescopic movement, the locking mechanism 2 is elastically locked in the relative rotational position between the handle assembly 1 and the frame 100 by the locking spring 202.

[0036] Furthermore, the locking mechanism 2 also includes a second locking block 201. The frame 100 is provided with a frame joint 7 having a lock hole 6, and the fixed frame 101 is provided with a handle joint 103. The handle joint 103 is rotatably connected to the frame joint 7, and the second locking block 201 is elastically and movably disposed on the handle joint 103. In the locked state of the locking mechanism 2, the second locking block 201 is elastically locked on the lock hole 6.

[0037] Furthermore, the second locking block 201 is provided with a receiving groove and a semi-circular hole communicating with the receiving groove. When the second locking block 201 is connected to the handle joint 103, the pin passes through the handle joint 103 and is inserted into the semi-circular hole. The locking spring 202 is installed on the receiving groove. One end of the locking spring 202 abuts against the inner side of the receiving groove of the second locking block 201, and the other end of the locking spring 202 abuts against the pin. When the second locking block 201 is disengaged from the lock hole 6, the locking spring 202 is compressed. When the locking spring 202 releases its elastic force, the second locking block 201 is inserted into the lock hole 6.

[0038] Furthermore, both the fastening member 502 and the second locking block 201 are provided with latches 8, and the fastening member 502 and the second locking block 201 are fastened together by the latches 8. The latches 8 ensure that the two are tightly and reliably fastened together, making it difficult for them to fall off or misalign, and ensuring the transmission effectiveness of the second unlocking member 4 driving the locking mechanism 2 to unlock through the interlocking mechanism 5.

[0039] Furthermore, the base 503 is provided with a movable block 504. The movable block 504 and the first locking block 501 both move linearly on the base 503 through elastic elements, and the movement directions of the movable block 504 and the first locking block 501 are different. The fastening member 502 is rotatably connected to the base 503 and the movable block 504 through a rotating shaft. A torsion spring is provided on the rotating shaft to make the fastening member 502 rotate elastically. The torsion spring acts on the base 503 and the fastening member 502 at both ends respectively. The rotating shaft passes through the base 503, the fastening member 502 and the movable block 504. The base 503 is provided with a clearance groove corresponding to the rotation trajectory of the fastening member 502. One end of the fastening member 502 extends toward the first locking block 501. The fastening member 502 is engaged or disengaged from the second locking block 201 by rotation.

[0040] Furthermore, the movable block 504 moves in a different direction than the first locking block 501 to avoid operational interference and ensure the independence and orderliness of the operation of the two unlocking components. The movable block 504 moves in the same direction as the second locking block 201 and is used to pull the second locking block 201 to unlock. The elastic rotation design of the fastening component 502 can realize the fastening component 502 and the second locking block 201 to be fastened or disengaged. When the handle assembly 1 is folded to the frame 100 and then unfolded again, when the user needs to adjust the extension length of the handle assembly 1, the fastening component 502 needs to be separated from the second locking block 201. Therefore, when adjusting the extension, when the first unlocking component 3 is operated, the first locking block 501 is driven to move laterally and retract into the handle 102, which can trigger the fastening component 502 to rotate and disengage from the second locking block 201. Then the user can pull the handle 102 to extend onto the fixed frame 101.

[0041] Furthermore, there is a spring between the movable block 504 and the base 503, which is compressed when the movable block 504 moves.

[0042] Furthermore, the first unlocking component 3 and the second unlocking component 4 are respectively connected to the first locking block 501 and the movable block 504 via the transmission component 9; When the first unlocking component 3 is operated, it drives the first locking block 501 to move through the transmission component 9 and triggers the fastening component 502 to rotate. The transmission component 9 is made of steel wire, rope, or chain.

[0043] Furthermore, the second unlocking component 4 is elastically pressed on the handle 1, and the handle 1 is provided with a slider 10. The slider 10 is connected to the first locking block 501 through the transmission component 9. The first unlocking component 3 is slidably disposed outside the handle 1 and is fixedly connected to the slider 10. The handle 1 is provided with a sliding groove 105, and one end of the first locking block 501 is embedded in the sliding groove 105 and fixedly connected to the slider 10.

[0044] Furthermore, the second unlocking component 4 is connected to the second unlocking component 4 via the movable block 504.

[0045] Furthermore, the mounting bracket 101 is provided with a plurality of linearly arranged locking slots 104. When the handle 102 is fixed to the mounting bracket 101, the first locking block 501 is locked in the corresponding locking slot 104. The multiple locking slots 104 provide multiple telescopic positions to meet the user's adjustment needs as much as possible.

[0046] In the initial state, the frame 100 and handlebar assembly 1 are in an unfolded and locked state: the handlebar 102 is locked to the corresponding locking groove 104 of the fixed frame 101 by the first locking block 501, and the handlebar assembly 1 is locked to the lock hole 6 by the second locking block 201 of the locking mechanism 2. The fastener 502 is not fastened to the second locking block 201.

[0047] When the handle assembly 1 needs to be folded, the first step is to operate the first unlocking member 3: the first unlocking member 3 drives the first locking block 501 to disengage from the locking groove 104 through the transmission member 9 and triggers the fastening member 502 to rotate. After the first locking block 501 disengages from the locking groove 104, the extension and retraction lock of the handle 102 is released. At this time, the handle 102 can be pushed to extend and retract along the fixing frame 101, driving the base 503 and the interlocking mechanism 5 to move as a whole, so that the fastening member 502 moves towards the second locking block 201 until the handle assembly 1 is shortened to the limit position. The first locking block 501 aligns with the corresponding locking groove 104, the first unlocking member 3 is released, the fastening member 502 rotates elastically, and the fastening member 502 is fastened to the second locking block 201 through the latch 8.

[0048] Furthermore, the second step involves operating the second unlocking component 4: the second unlocking component 4 drives the movable block 504 to move via the transmission component 9. The movable block 504 drives the fastening component 502, and the fastening component 502 pulls the second locking block 201 through the latch 8, overcoming the elastic force of the locking spring 202, disengaging from the lock hole 6, and releasing the locking mechanism 2. At this time, the handle assembly 1 can rotate relative to the frame 100 to fold, completing the folding process.

[0049] If only the extension length of the handle 102 needs to be adjusted, after the first unlocking member 3 unlocks the first locking block 501, push the handle 102 to the desired position, release the first unlocking member 3, and the first locking block 501 will automatically engage with the corresponding locking groove 104 to complete the extension adjustment. During this process, the fastening member 502 does not engage with the second locking block 201, the locking mechanism 2 remains locked, and the handle assembly 1 will not rotate.
