Detailed ways

As shown in the accompanying drawings, a child stroller includes a stroller frame 1, a front wheel assembly 2 arranged at the bottom front of the stroller frame 1, and a front wheel assembly 2 arranged at the bottom of the stroller frame 1. The rear wheel assembly 3 at the rear, the cart frame 1 includes an upper front wheel bracket 4, a lower front wheel bracket 5 that can be slidably arranged with the upper front wheel bracket 4, and the upper front wheel bracket 4 and the lower front wheel bracket 5 is provided with a sliding locking mechanism, the upper front wheel bracket 4 is detachably provided with an upper seat 13, and the lower front wheel bracket 5 is detachably connected with a lower Seat 14, the front part of described lower front wheel support 5 is provided with front wheel assembly 2. The conversion between the double-seater stroller and the single-seat stroller mainly depends on the upper front-wheel support 4 and the lower front-wheel support 5 and the sliding locking mechanism between the two. The structure of the sliding lock mechanism is also not limited, as long as it can be locked between the upper front wheel bracket 4 and the lower front wheel bracket 5 in sliding relationship, it can be used. As being provided with spring pin on upper front wheel support 4, and offer spring pin hole on lower front wheel support 5, promptly lock when spring pin is inserted in the spring pin hole, promptly unlock when spring pin and spring pin hole disengage.

The upper front wheel bracket 4 includes upper front side bars on both sides, and upper cross bar 6 connected between the upper front side bars on both sides, and the lower front wheel bracket 5 includes The lower front side bars on both sides, the lower cross bar 7 connected between the lower front side bars on both sides, that is, the upper front wheel bracket 4 and the lower front wheel bracket 5 constitute the front wheel bracket of both feet, each side The said upper front side bar is slidably arranged with the lower front side bar on the corresponding side. The front wheel support can also be monopod, which is located in the middle of both sides of the cart frame and protrudes outwards.

The lower front wheel bracket 5 is rotatably connected with a U-shaped lower seat frame 9 for installing the lower seat 14, specifically, the middle part of the lower seat frame 9 is connected to the lower seat frame 9. The lower cross bar 7 of the front wheel bracket 5 rotates and a lower locking mechanism is arranged between the two. The upper front wheel bracket 4 is rotatably connected with a U-shaped upper seat frame 8 for installing the upper seat 13. Specifically, the middle part of the upper seat frame 8 is connected to the upper front wheel. The upper cross bar 6 of the support 4 rotates and an upper locking mechanism is arranged between the two. Both sides of the lower seat 14 are detachably connected to both ends of the lower seat frame 9 . Both sides of the upper seat 13 are detachably connected to both ends of the upper seat frame 8 .

The structure of the upper locking mechanism and the lower locking mechanism is not limited, as long as it can be locked between the lower seat frame 9 and the lower front wheel support 5 and the upper seat frame 8 and the upper front wheel support 4 to get final product . As on the lower cross bar 7, there is a fixed spring pin seat with elastic pins, the lower seat frame 9 is rotatably connected with the elastic pin seat, and two spring pin holes are provided on the lower seat frame 9, and the lower seat frame 9 has the functions of unfolding and locking. Two positions are stowed away, when the spring pin is inserted into the spring pin hole, it is locked, and when the spring pin is separated from the spring pin hole, it is unlocked. When the lower seat frame 9 is in the deployed position, the lower seat 14 can be connected to the lower seat frame 9 . Likewise, when the upper seat frame 8 is in the deployed position, the upper seat 13 can be connected to the upper seat frame 8 .

The lower seat frame 9 and the upper seat frame 8 are used to place the lower seat 14 and the upper seat 13 at a higher position. And under the state that lower front wheel support 5 and last front wheel support 4 itself are in a higher position, also can directly lower seat 14 be connected on the lower front wheel support 5, last seat 13 is connected on the last front wheel support 4. Through the lower seat frame 9 and the upper seat frame 8, the lower seat 14 and the upper seat 13 can be in a higher position, which helps children avoid inhaling a large amount of dust.

The lower front side bar on each side is provided with a guide part extending along its length direction, the lower front side bar is connected to the limiting part through a neck, and the upper front side bar on each side A guide groove with a large inner cavity and a smaller opening is opened on the front side rod along its length direction, the guide part is located in the inner cavity of the guide groove, and the neck is located at the opening.

As shown in accompanying drawing 1, accompanying drawing 4, accompanying drawing 5, after lower seat 14 is disassembled from lower seat frame 9, lower locking mechanism is unlocked, and lower seat frame 9 is folded away. Unlock the sliding locking mechanism, place the lower front wheel support and the upper front wheel support in the retracted state, and at this time, a single-seat cart is formed.

Many children's strollers all have front wheel brackets with front wheel assemblies installed on the bottom, so the front wheel brackets can be set as upper front wheel brackets and lower front wheel brackets that can slide relatively, so as to meet the needs of realizing double-seater strollers and single-person strollers. The basic conditions of the stroller. This embodiment provides a cart frame structure with a relatively simple structure.

As shown in the accompanying drawings, the cart frame 1 also includes side brackets on both sides, a cross bar connected between the side brackets on both sides, and each side bracket includes an upper end The rear wheel support 11 that is rotatably connected with the upper front wheel support 4 through the first rotating shaft, the push rod 10 and the connecting rod 12 that are rotatably connected with the rear portion of the upper front wheel support 4 through the second rotating shaft , one end of the connecting rod 12 is rotationally connected with the lower part of the push rod 10 through the third shaft, and the other end of the connecting rod 12 is connected with the rear wheel bracket 11 through the fourth The rotating shafts are connected in rotation, and the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft are parallel to each other. Described upper front wheel support 4, push rod 10, connecting rod 12 (seeing accompanying drawing 2), rear wheel support 11 constitute four-bar linkage. Under the single-seat cart, the upper seat 13 is disassembled, and then the upper locking mechanism is unlocked, so that the upper seat frame 8 is folded away, and then the cart frame can be folded.

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.
