Detailed ways

As shown in the drawings, a stroller for children includes a foldable stroller frame, a front wheel assembly 1, a rear wheel assembly 2, and a locking mechanism capable of locking the stroller frame in an unfolded state.

The stroller frame includes two sets of side brackets symmetrically arranged left and right, and each set of side brackets includes a front bracket 3, a push handle bar 4, a rear bracket 5, a front seat post 6, a rear seat post 7, a first connecting rod 8, a second connecting rod rod 9 and slide 10. The front wheel assembly 1 is arranged at the lower end of the front frame 3 , and the rear wheel assembly 2 is arranged at the lower end of the rear frame 5 . An unlocking belt 11 is provided between the front ends of the two rear seatposts 7 on the left and right sides.

The upper end of the push rod 4 and the rear bracket 5 is rotatably connected through the third rotating shaft 14; The sixth rotating shaft 17 is rotatably connected; the two ends of the second connecting rod 9 are rotatably connected to the rear bracket 5 and the rear seat post 7 through the first rotating shaft 12 and the second rotating shaft 13 respectively; the sliding member 10 is along the rear bracket 5 The longitudinal direction of the slider is slidably arranged on the rear bracket 5. In this embodiment, the slider 10 is a sliding sleeve, and the sliding sleeve is slidably set on the rear bracket 5.

The front end of the push handle bar 4 is rotatably connected with the upper end of the front bracket 3 through the fourth rotating shaft 15, and the upper end of the first connecting rod 8 is rotatably connected with the push handle bar 4 and/or the front bracket 3 through the ninth rotating shaft. In this embodiment, as shown in Figures 1 to 4, the front end of the push handle bar 4, the upper end of the front bracket 3, and the upper end of the first connecting rod 8 are coaxially connected to each other, that is, the fourth rotating shaft 15 and the fourth rotating shaft 15. The nine rotating shafts are the same shaft. When the stroller frame was in the unfolded state, the front bracket 3 and the push handle bar 4 were approximately on the same straight line.

The rear seat post 7 is rotationally connected to the slider 10 through the seventh rotating shaft 18, and the lower end of the first connecting rod 8 is rotationally connected to the sliding member 10 through the eighth rotating shaft. In this embodiment, as shown in Figures 1 to 4, The rear seat post 7 , the lower end of the first connecting rod 8 , and the sliding member 10 are coaxially rotatably connected, that is, the seventh rotating shaft 18 and the eighth rotating shaft are the same shaft.

Because in this embodiment, the fourth rotating shaft 15 and the ninth rotating shaft are the same shaft, and the seventh rotating shaft 18 and the eighth rotating shaft are the same shaft, therefore, only the fourth rotating shaft 15 and the seventh rotating shaft 18 are carried out in each accompanying drawing. Note, the fourth shaft 15 and the ninth shaft are collectively described as the fourth shaft 15 , and the seventh shaft 18 and the eighth shaft are collectively described as the seventh shaft 18 .

The first rotating shaft 12 is located below the sliding member 10 , and the second rotating shaft 13 is located behind the rotational connection point (ie, the seventh rotating shaft 18 ) of the rear seat post 7 and the sliding member 10 . When the stroller frame is in the unfolded state, the fourth rotating shaft 15 is positioned at the front bottom of the third rotating shaft 14, the rear upper part of the fifth rotating shaft 16, the upper part of the sixth rotating shaft 17, and the upper front part of the seventh rotating shaft 18. Located behind the sixth rotating shaft 17, the third rotating shaft 14, the fourth rotating shaft 15, and the fifth rotating shaft 16 are approximately on the same straight line, and the fifth rotating shaft 16, the sixth rotating shaft 17, the seventh rotating shaft 18, and the second rotating shaft 13 are approximately on the same straight line. in a straight line. The axis lines of the first rotating shaft 12, the second rotating shaft 13, the third rotating shaft 14, the fourth rotating shaft 15, the fifth rotating shaft 16, the sixth rotating shaft 17, and the seventh rotating shaft 18 are parallel to each other and extend along the left-right direction of the stroller. .

The locking mechanism is arranged between the slider 10 and the rear support 5 for locking the two relative to each other. The specific structure of the locking mechanism is not the focus of the protection of the present utility model, as long as the relative locking of the sliding part 10 and the rear bracket 5 can be realized, for example, the following structure can be adopted: the cooperative locking of the locking part and the locking part, etc.

Working principle: When the stroller needs to be converted from the unfolded state to the folded state, the locking mechanism is unlocked, the unlocking belt 11 is pulled upwards, and the front end of the rear seatpost 7 and the rear end of the front seatpost 6 are driven to rotate upwards, and the front bracket 3 Driven to rotate towards the rear bracket 5, the slider 10 is driven to slide upwards, and the push bar 4 turns downwards under the action of gravity to approach the rear bracket 5, completing the conversion of the stroller from the unfolded state to the folded state.

When it is necessary to convert the stroller from the folded state to the unfolded state, pull the push handle bar 4 upwards, the rear end of the front seat post 6 and the front end of the rear seat post 7 rotate downward, and the front support 3 moves toward the side far away from the rear support 5. direction movement, the sliding member 10 slides downwards, the locking mechanism is locked again, and the transformation of the stroller from the folded state to the unfolded state is completed.

As mentioned above, we have fully described according to the purpose of the utility model, but the utility model is not limited to the above-mentioned embodiment and implementation method. Practitioners in the relevant technical fields can make different changes and implementations within the scope permitted by the technical ideas of the present utility model.
