As shown in fig. 1 to 4, a stroller frame with adjustable track width according to an embodiment of the present invention includes a main frame 100 and a sliding frame 200, wherein the main frame 100 includes a main support rod set 110 and a side support rod set 120, the main support rod set 110 is slidably provided with a first sliding member 510, one end of the side support rod set 120 is rotatably connected to the first sliding member 510, the other end of the side support rod set 120 is rotatably connected to a second sliding member 520, an end of the main support rod set 110 is rotatably connected to a third sliding member 530, the main frame 100 is provided with a first wheel set 300, the sliding frame 200 is provided with a second wheel set 400, the sliding frame 200 is slidably connected to the second sliding member 520 and the third sliding member 530, respectively, the main support rod set 110, the side support rod set 120, and the sliding frame 200 form a three-bar mechanism, and the sliding frame 200 can move relative to the main frame 100 to change a distance between the first wheel set 300 and the second wheel set 400, i.e. the track width of the stroller can be adjusted as required to meet different requirements.
Specifically, as shown in fig. 1 and 2, the distance between the first wheel set 300 and the second wheel set 400 is small, and at this time, the frame of the stroller can be shortened to be small, the operation and the placement are flexible, and the requirement of using a single seat can be met (as shown in fig. 6); as shown in fig. 3 and 4, the carriage 200 is pushed forward, so that the second wheel set 400 moves forward, the distance between the first wheel set 300 and the second wheel set 400 is increased, and the span and space for supporting are increased, so that two seats (as shown in fig. 7) can be installed, and the stability is high; as shown in fig. 5, the first sliding member 510, the second sliding member 520, or the third sliding member 530 can change the shape of the three-bar linkage when sliding relative to each other, so as to achieve the folded state, and the space occupied by the folding carriage 200 can be reduced, thereby facilitating the placement of the stroller.
In some embodiments of the present invention, at least one of the first slide 510, the second slide 520, and the third slide 530 can slide relative to the three-bar linkage, deforming the three-bar linkage to enable folding or unfolding of the stroller frame.
That is, the main support bar group 110, the side support bar group 120, and the carriage 200 form a three-bar linkage, and the shape of the three-bar linkage can be changed by using at least one sliding structure among the first slider 510, the second slider 520, and the third slider 530, thereby realizing folding and unfolding of the stroller frame.
Specifically, the sliding of the first slider 510, the second slider 520, and the third slider 530 with respect to the three-bar linkage means that the first slider 510 slides with respect to the main support bar group 110, or the second slider 520 slides with respect to the carriage 200, or the third slider 530 slides with respect to the carriage 200, so that the three-bar linkage is deformed
