The principle of locking and unlocking the locking device of the strut bar frame 200 of the child safety seat for a vehicle according to the present embodiment is explained in detail as follows:
referring to fig. 1 to 3, when the pressure bar frame 200 is in the open state, the locking device is in the unlocked state, at this time, the connecting portion 21 of the second locking piece 2 is in fit connection with the positioning portion 12 of the first locking piece 1, and the hook of the connecting portion 21 is hooked in the hook groove 122, so that the first locking piece 1 is suspended at the first position against the acting force of the first elastic piece; at this time, the third resilient member 7 is in a release state, and the second engaging element 4 is in the pop-up position.
Referring to fig. 4 to 6, when it is required to lock the lever arm 200 in the closed state, the locking end 202 thereof is pressed downward, so that the lever arm 200 rotates downward about the first axis 4001 and toward the base 100 until the pushing portion 22 of the second locker 2 contacts the second fitting member 4 located at the pop-up position, and the second fitting member 4 applies resistance to the pushing portion 22; when the pressing rod frame 200 is pressed further, the pushing portion 22 abuts against the second matching piece 4, the second locking piece 2 rotates around the second shaft 4002 against the acting force of the second elastic piece 6, the connecting portion 21 correspondingly rotates downwards and is disengaged from the positioning portion 12, the first locking piece 1 moves towards the second position under the acting force of the first elastic piece, so that the first locking piece 1 can be locked with the first matching piece 3 in a matched manner, and the locking end 202 of the pressing rod frame 200 and the base 100 are close to each other to press the connecting band 500 tightly; in the above process, the second fitting member 4 is always located at the pop-up position. When the locking device is in the locked state, the pushing portion 22 of the second locker 2 abuts against the upper surface of the second fitting member 4, and the connecting portion 21 of the second locker 2 abuts against the lower surface of the unlocking stage 121 of the first locker 1.
When the locking device needs to be unlocked, the locking end 202 of the pressure bar frame 200 only needs to be pressed down continuously, unlocking can be achieved through the following three unlocking processes, and then the pressure bar frame 200 is converted into an open state by lifting the locking end 202 and assisting the acting force of the fourth elastic piece. The three unlocking processes are specifically as follows:
referring to fig. 8 and 9, the first unlocking process: further push down locking end 202, first fitting piece 3 supports and leans on the unblock inclined plane of first latch fitting 1 and upwards slides along the inclined plane to exert reaction force to first latch fitting 1, make first latch fitting 1 overcome the effort of first elastic component and move towards first position, in this process, the couple groove 122 of first latch fitting 1 is close to each other with the couple of the connecting portion 21 of second latch fitting 2.
Referring to fig. 10 and 11, the second unlocking process: the locking end 202 is further pressed down until the hook groove 122 of the first locking member 1 moves to the upper side of the connecting portion 21 of the second locking member 2, and then the connecting portion 21 moves toward the hook groove 122 under the action of the second elastic member 6, and the two are connected in a matching manner, so that the first locking member 1 is suspended at the first position again, and at this time, the acting force on the pressure bar frame 200 is removed, so that the pressure bar frame 200 rotates upward under the acting force of the fourth elastic member.
Referring to fig. 12 and 13, the unlocking process is three: the push rod bracket 200 continues to rotate upward under the action of the fourth elastic member, and since the first locking member 1 is maintained at the first position, the locking portion 11 is not engaged with the first mating member 3 any more, but directly passes over the first mating member 3 from bottom to top; in this process, the pushing portion 22 of the second locking member 2 abuts against the second matching member 4, but because the upper surface of the pushing portion 22 is an arc surface, the pushing portion 22 cannot be interfered by the second matching member 4 to rotate, but pushes the second matching member 4 forward to a retraction position, when the second locking member 2 moves to the upper side of the second matching member 4, the two are disengaged, the second matching member 4 returns to a pop-up position under the acting force of the third elastic member 7, so far, the locking device completes unlocking, and the pressure bar frame 200 can be switched to an open state.
In conclusion, the child safety seat for the automobile can be locked by pressing down the pressure bar frame 200 for the first time, and can be unlocked by pressing down the pressure bar frame again, so that the child safety seat for the automobile is very convenient and fast.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
