[ detailed description ] embodiments

The invention will be further described with reference to the accompanying drawings:

as shown in fig. 1 to 4, the infant stroller comprises a foldable frame 1 with a support rod 11 and a seat assembly 2 with a back plate 21, wherein the seat assembly 2 is connected to the frame 1 and can be locked with the frame 1 through a locking mechanism 3, the locking mechanism 3 comprises a locking seat 31 arranged on the back plate 21, a sliding seat 32 capable of sliding along the support rod 11 is arranged on the support rod 11, and a locking position 33 capable of locking or unlocking with the locking seat 31 when the sliding along the support rod 11 is arranged on the sliding seat 32. Therefore, when the stroller is unfolded, the slide seat 32 slides in the extending direction of the support bar 11 and is locked to the lock seat 31, and the lock mechanism 3 of the stroller is not locked by moving in the front-rear direction of the stroller any more, so that the lock seat 31 of the back plate 21 is not separated from the lock seat 33 of the slide seat 32 even if the seat assembly 2 receives a large external force toward the front of the stroller, thereby ensuring safety and preventing a potential safety hazard. When the infant stroller is required to be folded, the locking mechanism 3 can be unlocked only by sliding the sliding seat 32 along the support rod 11, and the whole locking mechanism has a simple structure and good safety. Of course, an equivalent structure may be provided, in which the support rod 11 is provided with a locking seat, the backboard is provided with a sliding seat capable of sliding up and down along the backboard, and the sliding seat is provided with a locking position capable of being locked with or separated from the locking seat.

As shown in fig. 2 to 4, the latch seat 31 includes a protrusion plate 311 provided on the back plate 21, the protrusion plate 311 is provided with an extension piece 312 extending to a side surface thereof, the latch position 33 includes a latch groove 331 into which the protrusion plate 311 and the extension piece 312 can be inserted, and a stopper 332 capable of preventing the extension piece 312 from being released toward the front of the infant car when the latch position 33 is engaged with the latch seat 31. When the latch seat 31 is engaged with the latch seat 33, the protruding plate 311 and the extending block 312 are both located in the latch groove 331, and the extending block 312 abuts against the stopper 332, so that the stopper 332 prevents the latch seat 31 from being disengaged in the front direction of the stroller, thereby eliminating potential safety hazards.

As shown in fig. 2 and 3, the latch seat 31 has a T-shaped cross section, and the latch groove 331 is matched with the T-shaped latch seat 31. Through the T-shaped locking seat 31 and the T-shaped locking groove 331 which are matched for locking, the locking and unlocking operations are convenient, the locking mechanism 3 can be unlocked only when the sliding seat 32 slides along the supporting rod 11, and the safety is ensured.

As shown in fig. 2, a blocking portion 313 capable of preventing the sliding seat 32 from being separated from the latch seat 31 when sliding downward is disposed between the lower end of the extension block 312 and the back plate 21. The stop 313 is provided to facilitate the position of the slide holder 32 to be limited by the locking mechanism 3 when locked.

As shown in fig. 1 and 2, a retaining device 34 is provided between the latch seat 31 and the back plate 21 to prevent the latch seat 31 from sliding along the support rod 11 when the latch seat 31 is engaged with the latch seat 33. When the locking mechanism 3 is locked, the anti-falling device 34 prevents the sliding seat 32 from sliding along the support rod 11 and is unlocked mistakenly, so that the sliding seat 32 can only slide after the anti-falling device 34 is released, the double-protection effect is achieved, and the safety is ensured.

As shown in fig. 2, two sets of the anti-slip devices 34 are disposed at two sides of the latch seat 31, the anti-slip device 34 includes an anti-slip rod 341 exposed from the latch seat 31 and capable of sliding in the latch seat 31 along the front and rear direction of the stroller, the back plate 21 is provided with a locking hole 342 capable of being engaged with the anti-slip rod 341, and the latch seat 31 is further provided with a return spring (not shown) capable of returning to the anti-slip rod 341. When the stroller needs to be folded, the anti-falling rod 341 is pulled first, the return spring is compressed, the anti-falling rod 341 is separated from the locking hole 342 on the back plate 21, and at this time, the sliding seat 32 can be slid to complete the unlocking of the locking mechanism 3. When the stroller is unfolded, the return spring presses the escape bar 341 to keep the escape bar 341 engaged with the engaging hole 342.
