Detailed Description

The invention is described in further detail below with reference to the figures and specific examples.

As shown in fig. 1 to 4, a locking mechanism of a children product is described below with the children product as a child seat pocket, but the locking mechanism may also be applied to other children products such as a stroller;

in this embodiment, the child seat bag includes a connecting seat 100, a grab bar 10 (first rotating member), a back lever (second rotating member), a seat lever 30, and a pedal lever 301 rotatably connected to the front end of the seat lever 30, wherein the seat lever 30 is fixedly connected to the connecting seat 100, the grab bar 10 and the back lever are both rotatably connected to the connecting seat 100, and the rotation axis of the back lever is located below the rotation axis of the grab bar 10.

The locking mechanism comprises a locking unit for locking the grab rail 10 and the connecting seat 100 relatively and an unlocking unit for unlocking the locking unit, and a transmission structure is formed between the backrest rod and the unlocking unit.

The locking unit comprises a locking hole 40 formed on the connecting base 100, a locking member 41 slidably disposed on the grab bar 10, and an elastic member 42 tending to drive the locking member 41 to slide into the locking hole 40, wherein the elastic member 42 abuts against a side of the locking member 41 away from the locking hole 40.

The unlocking unit comprises a sliding assembly arranged in the connecting seat 100 in a sliding manner, the sliding assembly comprises a first sliding block 51 sliding along the seat pocket in the up-down direction and a second sliding block 52 sliding in the direction approximately perpendicular to the first sliding block 51, in addition, the first sliding block 51 is provided with an initial position and an action position in the sliding direction, the locking unit is unlocked when the first sliding block is in the action position, and the unlocking unit also comprises a restoring piece 53 (a spring) tending to push the first sliding block 51 to move from the action position to the initial position. The return member 53 abuts against an end of the first slider 51 away from the club head 201.

When the locking unit is unlocked, the backrest rod needs to rotate to approach the seat rod 30, the first slider 51 is pushed to slide upwards through the transmission structure while the backrest rod rotates, the first slider 51 pushes the second slider 52 to slide to one side, when the second slider 52 slides, the locking piece 41 can be ejected out of the locking hole 40 from the inner side of the locking hole 40, and then the locking unit is unlocked, and at the moment, the handrail rod 10 can rotate downwards under the action of the dead weight of the handrail rod and approach the seat rod 30.

Specifically, the back rest lever includes a lever body 202 and a lever head 201, the cross section of the lever head 201 is circular, and the lever head 201 is located below the first slider 51. An avoiding groove 2010 extending along the circumferential direction is arranged on the outer circumferential surface of the round club head 201, the groove wall at one side of the avoiding groove 2010 is inclined and forms a first transmission inclined surface m1, the side of the first slide block 51 close to the club head 201 is formed with a second transmission inclined surface m2 matched with the first transmission inclined surface m1, the first transmission inclined surface m1 and the second transmission inclined surface m2 form the transmission structure, in addition, the side of the first slide block 51 close to the second slide block 52 is respectively formed with a third transmission inclined surface m3 and a fourth transmission inclined surface m4, so when the seat pocket folding bar rotates towards the seat bar, the first transmission inclined surface m1 on the club head 201 is contacted with the second transmission inclined surface m2 on the first slide block 51, the club head 201 rotates to make the second transmission inclined surface m2 contacted with the first transmission inclined surface m1 to push the first slide block 51 to move upwards, and the third transmission inclined surface m3 on the first slide block 51 is contacted with the fourth transmission inclined surface m4 on the second slide block 4, the first slide block 51 pushes the second slide block 52 to move, so that the second slide block 52 moves along the sliding direction thereof, and finally the second slide block 52 pushes the locking member 41, so that the locking member 41 is disengaged from the locking hole 40, and the locking unit is unlocked.

When the seat pocket is in the unfolded and locked state, the lower end of the first slider 51 is positioned in the avoiding groove 2010, and when the seat pocket is in the folded state, the lower end of the first slider 51 is positioned outside the avoiding groove 2010 and abuts against the outer circumferential surface of the rod head 201.

After the locking unit is unlocked, the grab bar 10 can rotate towards the seat bar 30 to approach under the action of the dead weight of the grab bar, then the back rest bar can rotate forwards to approach the grab bar 10, the seat pocket is folded, the first slide block 51 is always positioned at the action position in the folded state of the seat pocket, at the moment, the first slide block 51 is abutted against the circumferential surface of the rod head 201, the restoring piece 53 is also positioned at the compressed force accumulation state, therefore, when the seat pocket is unfolded again, the back rest bar rotates reversely until the avoiding groove 2010 corresponds to the first slide block 51, the first slide block 51 moves to the initial position under the action of the restoring piece 53, at the moment, the first slide block 51 is abutted against the groove bottom of the avoiding groove 2010, when the grab bar 10 moves to the position where the locking piece 41 corresponds to the locking hole 40, the second slide block 52 loses the abutting force of the first slide block 51, so that the second slide block 52 can not be abutted against the locking piece 41 any more, finally, the locking element 41 slides into the locking hole 40 under the urging of the elastic element 42, and the locking is completed.

In this embodiment, the grab bar 10 is rotatably connected to the connecting seat 100 through the first rotating shaft z1, the back bar is rotatably connected to the connecting seat 100 through the second rotating shaft z2, and the first rotating shaft z1 and the second rotating shaft z2 are staggered in the vertical direction, so that the connecting seat 100 can be longer in the vertical direction, and the requirement of the overall design of some seat pockets or children products is met, because the first rotating shaft z1 needs to penetrate through the first slider 51 and the first slider 51 needs to slide vertically, the first slider 51 is provided with a kidney-shaped groove avoiding the first rotating shaft z 1.

Further, referring to fig. 3, an escape groove 2010 on the outer periphery of the head 201 can escape the first slider 51 when the back lever is rotated to the lying position. The corresponding central angle of the escape groove 2010 is 60 ° or more and 70 ° or less.

In summary, the locking mechanism of the invention is applied to a seat bag for children, when the seat bag is folded, the unlocking of the grab bar does not need manual operation, and through the design of the locking unit, the unlocking unit and the transmission structure, the aim of automatically unlocking the grab bar can be achieved only by rotating the backrest bar to approach the seat bar after the backrest bar is unlocked, the operation is more convenient, and the use experience is improved. In addition, the invention only adopts the sliding component through the transmission structure, has reasonable and compact structure and meets the requirements of the overall design of different child seat pockets or children products.

The present invention is described in detail in order to make those skilled in the art understand the content and practice the invention, and the invention is not limited to the above embodiments, and all equivalent changes or modifications made according to the spirit of the invention should be covered by the scope of the invention.
