A rotating hook mounting portion 233 is further disposed on the inner end of the sliding tube 23 adjacent to the second fixed main member 12, and the rotating hook mounting portion 233 is located downstream of the fourth sliding hole 232.

As shown in FIG. 2 and FIG. 4 , the unlocking assembly 30 includes an unlocking movable component 31 , an unlocking fixing component 32 , a gear shifting lock 33 and a rotating hook 34 , and the elastic binding between the unlocking movable component 31 and the unlocking fixing component 32 , specifically, The two ends of the unlocking fixing member 32 are respectively fixed on the corresponding sliding tube 23, and the unlocking movable assembly 31 and the unlocking fixing member 32 are movably connected by an elastic member (such as a spring), that is, the unlocking movable assembly 31 can be unlocked toward or away from the unlocking member 31. The direction of the fixing member 32 is moved.

The unlocking movable component 31 includes a pull rod 311 and a sliding pin 312. Each of the two ends of the sliding rod 311 is fixed with a sliding pin 312, and the other end of the sliding pin 312 passes through the fourth of the sliding tube 23. The sliding hole 232 extends into the first sliding hole of the second connecting rod 222, thereby achieving a slidable connection of the unlocking movable assembly 31 and the sliding assembly 20.

The gear lock 33 is mounted in the second sliding hole 2223 of the second connecting rod 222 and can pass through the fourth sliding hole 232 of the sliding tube 23 at both ends, and is in contact with the rotating hook 34 for limiting the rotating hook 34. Bit. An elastic member 331 (such as a spring) is also preferably mounted on the gear lock 33.

The rotating hook 34 is rotatably mounted on the rotating hook mounting portion 233 of the sliding tube 23, and when the unlocking assembly 30 is in the locked state, the rotating hook 34 is caught on the gear slot 13 of the second fixed body 12 of the main assembly 10, and the lock is locked. When the unlocking assembly 30 is in the unlocked state, the rotating hook 34 is rotated out from the gear position groove 13 by the force of the pull rod 311 or the sliding assembly 20 to realize separation from the gear position groove 13. A reset member 341 (such as a torsion spring) is also mounted on the rotating hook 34.

The working principle of the one-key unlocking device of the child seat of the present invention is mainly divided into three states: an initial state, an unlocking adjustment state, a locking and a one-button unlocking state.

As shown in FIG. 5 and FIG. 6, in the initial state, the isofix connection locking hook 212 is in an open state (ie, not locked with the car seat isofix connecting rod on the car seat), the opening thereof faces outward; the rotating hook 34 is a lock. In the dead state (ie, the rotating hook 34 locks the gear shifting groove 13), the sliding assembly 20 is in the minimum stroke position (ie, the sliding assembly 20 is not pulled out), and the entire device is in a locked state and cannot be moved. That is, the child seat has not been mounted to the car seat at this time, and the installation position of the child seat has not been adjusted, and the slide assembly 20 is maximally accommodated in the base of the child seat.

7 and FIG. 8, the adjustment state is: when a force is applied to the pull rod 311 toward the approaching unlocking member 32 (ie, the right direction in the drawing) and greater than 50 N, the pull rod 311 is moved to the right, and The sliding pin 312 fixed by the pull rod 311 drives the connecting member 22 to move to the right along the fourth sliding hole 232 of the sliding tube 23, and the connecting member 22 moves to the right while the ISOFIX connecting hook 212 is unlocked with the car seat isofix connecting rod, and the ISOFIX connection is performed. The lock hook 212 is in an open state. When the pull rod 311 is moved to the right, the swing hook 34 is on the pull rod 311. The oblique force of the two ends rotates away from the gear position groove 13 (the clockwise direction of the upper end rotating hook 34, and the lower end rotation hook 34 is counterclockwise), which drives the gear lock 33 to overcome its own elasticity. The spring force of the member 331 is moved toward the outer side of the slide tube 23 (in the upper end, the upper position lock 33 is in the upward direction, and the lower end lock 33 is in the downward direction). Then the rotary hook 34 is moved from the second fixed main body of the main assembly 10. The gear slot 13 of the member 12 is rotated out. This action enables unlocking of the movable assembly, and the movable assembly is movable back and forth relative to the main assembly 10 along the third sliding hole 231 of the slide tube 23. Thereby, the position of the child seat in the state of being unlocked with the car seat can be adjusted.

On the contrary, after the force applied to the pull rod 311 disappears, the pull rod 311 realizes automatic stroke reset under the force of the elastic member 35 (such as a spring) between the pull rod 311 and the unlocking fixing member 32, so that the rotating hook 34 is in the gear position. The lock 33 is re-engaged into the corresponding gear position slot 13 to achieve locking between the movable component and the main assembly 10.

That is, before the child seat is mounted on the car seat, the slide assembly 20 can be pulled out from the base of the child seat by the unlocking assembly 30, and the specifically pulled stroke position can be adjusted according to different gear positions. After adjusting to the appropriate position, the entire mechanism can be re-locked.

As shown in FIG. 9 and FIG. 10, the locking and one-button unlocking state: when the overall mechanism is in the locked state, a round bar 40 having a diameter of, but not limited to, 6 mm (such as a car seat isofix connecting rod) is stuck. The isofix is connected in the opening of the locking hook 212, and is moved to the right to rotate the isofix connecting hook 212 downward, and the isofix connecting the locking hook 212 locks the round bar 40, thereby realizing the locking between the sliding assembly 20 and the round bar 40 (for example, Installation between child seat and car seat). When the isofix connection lock hook 212 moves to the left while the gear position lock 33 is moved to the left, the rotation hook 34 has no limit of the gear position lock 33, and the rotation function is restored. When the slide assembly 20 is acted upon to the right (e.g., action 1), the rotary hook 34 can be rotated away from the gear shift slot 13 against the force of its reset member 341 (e.g., torsion spring). Since the rotating hook 34 does not lock the gear position groove 13, when the sliding assembly 20 is biased to the right In the continued case, the slide assembly 20 can be moved all the way to the right to the maximum position of the stroke (ie, to the minimum formed position of the initial state). When the force to the right disappears, the rotating hook 34 is snapped into the gear shift groove 13 by the torsion spring force, thereby achieving the function locking of the slide assembly 20.

When a force to the right and greater than 50 N is applied to the pull rod 311, the ISOFIX connecting device and the entire one-key unlocking adjustment mechanism are simultaneously unlocked. For the principle of the specific unlocking process, refer to the description in the above adjustment state, and details are not described herein again.

The technical content and the technical features of the present invention have been disclosed as above, but those skilled in the art can still make various alternatives and modifications without departing from the spirit and scope of the present invention based on the teachings and disclosures of the present invention. Therefore, the scope of protection of the present invention should not be limited to The disclosure of the embodiments is intended to cover various alternatives and modifications of the inventions
