Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to specific conditions, and the conditions used in the experiments are not specifically mentioned.

As shown in fig. 1 to 8, a stroller includes a push rod assembly 1, a front frame assembly 2, a rear frame assembly 3, a front wheel assembly 10 installed below the front frame assembly 2, a rear wheel assembly 11 installed below the rear frame assembly 3, and a slide rod 4. Push rod subassembly 1 lower part 2 upper portion of fore-stock subassembly respectively with 3 upper portions of rear bracket component are rotated and are connected, just fore-stock subassembly 2 with the swivelling joint point of rear bracket component 3 is located push rod subassembly 1 with the preceding below of the swivelling joint point of rear bracket component 3. The rear end of the sliding rod 4 is rotatably connected with the lower end of the push rod component 1, and the front support component 2 is provided with a sliding sleeve 5 which is in sliding fit with the sliding rod 4.

In this embodiment, the push rod assembly 1 comprises a lower push rod 1-1 rotatably connected with the rear support assembly 3 and an upper push rod 1-2 rotatably connected with the upper part of the lower push rod 1-1; a push rod locking mechanism for locking the push rod assembly 1 when the push rod assembly 1 is at the unfolding position is arranged between the upper push rod 1-2 and the lower push rod 1-1. Since the locking mechanism between the two-stage push rod assemblies is a common locking mechanism in the art, further description and structural limitations are not required.

In this embodiment, a frame locking mechanism 6 for locking the frame when the stroller is in the unfolded position is disposed between the lower push rod 1-1 of the push rod assembly 1 and the rear support assembly 3, and the locking mechanism between the two rotating components is a common mechanism in the art, so details and structural limitations are not described herein. Preferably, the frame locking mechanism 6 and the push rod locking mechanism are linked locking structures, and when the upper push rod 1-2 and the lower push rod 1-1 are folded, the locking of the frame locking mechanism 6 is automatically released. Since the linkage locking structure is a common structure in the art, further description and structural limitations are not required.

The working principle of the utility model is as follows: when the stroller needs to be folded and folded, the locking of the upper push rod 1-2 and the lower push rod 1-1 by the push rod locking mechanism is only needed to be released, then the upper push rod 1-2 is turned forwards, the locking of the frame locking mechanism 6 is automatically released when the push rod assembly 1 is folded, the push rod assembly 1 is pressed downwards at the moment, the push rod assembly 1 is turned backwards and folded at the rear side of the rear support assembly 3, and the slide rod 4 is driven to move forwards relative to the sliding sleeve 5, so that the front support assembly 2 is driven to turn backwards and folded at the front side of the rear support assembly 3, and the folding of the whole stroller is completed.

In this embodiment, the lower push rod 1-1 is rotatably connected with a front armrest assembly 7. In order to realize the automatic folding of the front armrest assembly 7 when the whole vehicle is folded, a connecting rod 8 is rotatably connected between the extension part of the front armrest assembly 7 and the upper part of the rear support assembly 3; when the push rod component 1 is folded and furled relative to the rear support component 3, the connecting rod 8 drives the front handrail component 7 to turn downwards and furl relative to the push rod component 1.
