[0036] The utility model provides a foldable baby stroller with handrails, see Figures 1 to 13 As shown, it includes a driving member 1, a linkage assembly and an armrest assembly, wherein the driving member 1 is connected to the handle assembly 100 and / or the seat 200. When folded, the handle assembly 100 and / or the seat 200 can synchronously drive the driving member 1 to move, that is, the driving member 1 is driven to change its angle during the folding process of the handle assembly 100 and / or the seat 200 because the handle assembly 100 and the seat 200 change their angles;

[0037] The driving member 1 is here configured as a sheet iron block, and can of course be replaced by a strip or rod-shaped connecting rod, or a structural product such as a steel rope;

[0038] A linkage assembly, wherein a first end of the linkage assembly is connected to the driving member 1;

[0039] The armrest assembly 3 is connected to the second end of the linkage member. When the driving member 1 moves, it can drive the linkage member to unlock the armrest assembly 3 to allow the armrest assembly 3 to rotate and fold.

[0040] The armrest assembly 3 includes an armrest 31, an armrest seat 32 arranged at the free end of the armrest 31, and a clamp 33 that can limit the movement of the armrest 31. The armrest seat 32 is provided with a first clamping groove 321 for the clamping groove 33 to be clamped into, a second clamping groove 202 is provided at the position corresponding to the first clamping groove 321 at the lower part of the seat 200, a clamping seat 201 is provided at the lower part of the seat 200, and the second clamping groove 202 is provided on the clamping seat 201.

One end of the third return spring 24 is connected to the sleeve column, and the other end is abutted against a top rod extending into the first groove 212 from the outside. When the first middle piece 21 slides, the top rod does not move with the first middle piece 21. When the external force pulls the first middle piece 21 to act on the third return spring 24, the third return spring 24 will be deformed and store elastic potential energy. Once the external force on the first middle piece 21 is cancelled, the third return spring 24 will use its stored elastic potential energy to restore the first middle piece 21 to its starting position.

[0046] The linkage assembly includes a second middle member 25 , which is disposed in a receiving groove below the seat 200 and can slide in the receiving groove, and a first end of the second middle member 25 is connected to the driving member 1 .

[0048] The middle piece adopts a second middle piece 25 including a second body 251, a third slide groove 252 and a fourth slide groove 253 arranged on the first body 211, the third slide groove 252 and the fourth slide groove 253 are arranged in an eight-shaped layout, and the zinc alloy heads of the two second steel ropes 26 can slide in the third slide groove 252 and the fourth slide groove 253 respectively. Specifically, when the two second steel ropes 26 are pulled by external force, the zinc alloy heads can slide in the third slide groove 252 and the fourth slide groove 253.

[0049] In the present invention, the steel rope linkage method is preferably used, but other methods such as the following can also be used instead:

[0050] The first type is the mechanical linkage structure: This structure connects different parts through a series of mechanical linkages to achieve a linkage effect. For example, when the backrest of the stroller is adjusted, the mechanical linkage can drive other parts such as the frame or wheels to move or adjust accordingly.

[0051] The second type is gear transmission: it uses the meshing of gears to transmit power and change the direction of movement. In a baby stroller, the seat, backrest or frame can be linked together through gear transmission.

[0052] The folding and closing operation of the utility model is synchronously driven by the handle assembly 100 and the seat 200 changing their postures during the folding and closing operation.

[0053] 1. The working principle of the first embodiment of the utility model is described as follows (the middleware in this case is the first middleware 21):

[0054] 1. When folding, the handle assembly 100 rotates forward, the angle of the driving member 1 changes, pulling the first steel rope 22 to make the first middle member 21 slide, the first middle member 21 synchronously drives the second steel rope 26, and the second steel rope 26 drives the clamp 33 to slide. When the handle assembly 100 is turned to the armrest 31 position (such as Figure 3 As shown in the position, the card member 33 is disengaged from the first card slot 321 and unlocked, and the armrest assembly 3 automatically rotates to be roughly parallel to the seat 200, completing the automatic folding function of the armrest 31.

[0055] 2. During the unfolding of the armrest, the handlebar assembly 100 links the driving member 1, the seat 200, and the front support 300 to unfold upward. During the unfolding process, the angle of the driving member 1 changes, and the first steel rope 22 returns under the thrust of the second return spring 23. The first middle member 21 also returns under the thrust of the third return spring 24, and the clamping member 33 also returns. At this time, after the hand rotates the armrest 31 to return, the clamping member 33 clamps the first clamping groove 321 of the armrest seat 32 to complete the unfolding operation of the armrest 31.

[0056] 2. The working principle of the second embodiment of the utility model is described as follows (the middleware is the second middleware 25 in this case):

[0057] 1. When folding, the handlebar assembly 100 rotates forward, the angle of the driving member 1 changes and leaves the second middle member 25, the driving spring 28 pushes the second middle member 25 to slide forward, the second middle member 25 synchronously drives the second steel rope 26, and the second steel rope 26 drives the clamping member 33 to slide. When the handlebar assembly 100 is turned to the armrest 31 position, the clamping member 33 disengages from the first clamping slot 321 and unlocks, and the armrest assembly 3 automatically rotates to be roughly parallel to the seat 200, completing the automatic folding function of the armrest 31.

[0058] 2. When the armrest is unfolded, the handlebar assembly 100 links the movable part, the seat 200 and the front support 300 to unfold upward. During the unfolding process, the angle change of the driving member 1 pushes the second middle member 25 back to its original position, and the synchronous clamping member 33 / the second steel rope 26 returns to its original position under the thrust of the first return spring 35. At this time, after the hand rotates the armrest 31 to return to its original position, the clamping member 33 is clamped in the first clamping groove 321 of the armrest seat 32 to complete the unfolding operation of the armrest 31.

[0059] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
