The fixing base 45 is pivotally connected to the first connecting base 41 and detachably connected to the frame of the stroller. Specifically, the following:
Referring to fig. 3, the armrest connecting seat 42 is provided with an arc-shaped groove 421, and the arc-shaped groove 421 is semicircular; the second connecting seat 43 is provided with a first positioning block 431 and a positioning part 432, and the positioning part 432 is positioned beside one side of the first positioning block 431; the first positioning block 431 is relatively slidably disposed in the arc-shaped groove 421, the first connecting seat 41 is provided with a second positioning block 411, the second positioning block 411 is slidably disposed through the arc-shaped groove 421, when the foldable handrail 4 is unfolded, the first positioning block 431 and the second positioning block 411 are respectively disposed at two ends of the arc-shaped groove 421 to position the handrail connecting seat 42, when the handrail 44 is folded, the second positioning block 411 slides to be close to the first positioning block 431 relative to the arc-shaped groove 421, and the second positioning block 411 is clamped to the positioning portion 432. The positioning portion 432 is a spring plate, and when the armrest 44 is folded, the second positioning block 411 passes over the spring plate and is engaged with the spring plate. The spring piece has the automatic resetting capability, so that the purpose of automatic positioning can be realized.
Referring to fig. 6 to 8, the armrest 44 is detachably connected to the armrest connecting seat 42. Specifically, a connection post 422 extends outwards from any one of the armrest 44 and the armrest connection seat 42, a connection post 422 extends outwards from the outer side of the armrest connection seat 42, a connection hole 422a is formed in the middle of the connection post 422, a matching hole 441 is formed in the armrest 44 in an inwards recessed manner, and the connection post 422 is sleeved in the matching hole 441.

With reference to fig. 4 and 5, the folding process of the infant carrier 100 of the present invention is described in detail as follows:
when the bicycle is folded, the upper frame 1 is manually pushed, so that the upper frame 1 rotates towards the direction close to the lower frame 2, at this time, the upper frame 1 drives the first connecting seat 41 to rotate relative to the second connecting seat 43, and the arc-shaped groove 421 and the first positioning block 431 slide relative to each other; at this time, the armrest coupling seat 42 is released, and the armrest 44 is folded along with the rotation of the backrest. When the upper frame 1 and the armrest 44 are completely folded with respect to the lower frame 2, the first positioning block 431 slides from one end of the arc-shaped groove 421 to the other end of the arc-shaped groove 421, and when the first positioning block 411 reaches the other end of the arc-shaped groove 421, the second positioning block 411 passes over the spring piece and is engaged with the spring piece, so that the upper frame 1 is positioned with respect to the first connection seat 41 and the armrest connection seat 42. When the seat is unfolded, in the process that the upper frame 1 is unfolded relative to the lower frame 2, the positioning block 411 on the first connecting seat 41 drives the armrest connecting seat 42 through the end of the arc-shaped slot 421, so that the armrest reaches the unfolded state and is positioned along with the locking of the first connecting seat 41 and the second connecting seat 43.
When the frame is unfolded, the upper frame 1 is manually pulled, the second positioning block 411 passes over the spring piece and is disengaged from the spring piece, and the upper frame 1 is rotated in a direction away from the lower frame 2; in this case, the first coupling seat 41, the armrest coupling seat 42, and the second coupling seat 43 are operated in a reverse manner to the folding operation, so that the upper frame 1 and the armrest 44 can be unfolded directly.
When the armrest 44 needs to be detached from the armrest connecting seat 42, only by manually pressing the button 462, the button 462 compresses the compression spring and drives the engaging hook 461 to move in the armrest 44, so that the engaging hook 461 is disengaged from the engaging hole 422 b; at this time, the armrest 44 and the armrest connecting seat 42 are unlocked, and the armrest 44 can be detached.
When the armrest 44 needs to be mounted on the armrest connecting seat 42, the reinforcing plate 442 only needs to be inserted into the connecting hole 422a, the connecting rod 422 is then sleeved in the fitting hole 441, and the engaging hooks 461 correspond to the engaging holes 422b, at this time, the engaging hooks 461 automatically engage with the engaging holes 422b under the elastic force of the compression spring, so that the armrest 44 and the armrest connecting seat 42 are locked, and the two can be connected together.
Compared with the prior art, the first connecting seat 41 is fixedly connected to the upper frame 1 of the infant carrier 100, the armrest 44 is connected to the armrest connecting seat 42, the armrest connecting seat 42 is pivoted with the first connecting seat 41, and the second connecting seat 43 is pivoted to the armrest connecting seat 42, so that the armrest 44 and the backrest can be synchronously folded, and can be folded relative to the lower frame 2 of the infant carrier 100, the operation is simple, the occupied space is effectively reduced, and the carrying convenience is improved; in addition, the armrest connecting seat 42 is provided with the arc-shaped groove 421, the first connecting seat 41 is provided with the second positioning block 411, and the second connecting seat 43 is provided with the first positioning block 431 slidably disposed on the arc-shaped groove 421 and the positioning part 432 for positioning the second positioning block 411, so that the backrest and the armrest 44 of the infant carrier 100 can be positioned when being unfolded, and the backrest and the armrest 44 can be more conveniently unfolded or folded.
The upper frame 1 may be a handle tube or a backrest tube in the infant carrier 100, and the lower frame 2 may be a seat tube, a front leg tube, or a footrest tube in the infant carrier 100, without affecting the operation of the foldable armrest 4.
The above disclosure is only for the preferred embodiment of the present invention, and it should be understood that the scope of the present invention is not limited thereto, and therefore, the equivalent changes made in the claims of the present invention are included in the scope of the present invention.
