Description

Technical Field

[0001] This utility model relates to a stroller seat assembly and a stroller equipped with the stroller seat assembly. Background Technology

[0002] A stroller is a tool vehicle designed to facilitate infants' outdoor activities. Among them, folding strollers are compact, lightweight, easy to operate, easy to carry, and easy to fold, bringing convenience to mothers when they go out and reducing the labor intensity of mothers or other people carrying infants.

[0003] Existing folding strollers generally include a frame and a seat. After being folded and stored, they can be placed in the trunk of a car. However, the seat components of typical folding strollers tend to spring back after being folded, making them inconvenient to store independently. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a stroller seat assembly that does not spring back after being folded, is convenient for independent placement, and has a simple structure.

[0005] The purpose of this invention is to provide a stroller with a simple stroller seat assembly that does not spring back after being folded, is easy to place independently, and has a simple structure.

[0006] The purpose of this utility model is achieved as follows:

[0007] A stroller seat assembly includes a backrest assembly, an armrest assembly, and a footrest assembly. The backrest assembly has a backrest pivot, the armrest assembly has an armrest pivot connected to the backrest pivot, and the footrest assembly has a footrest pivot connected to the backrest pivot. A locking seat is provided on the outer side of the footrest pivot. The stroller is characterized by a folding switch assembly between the backrest pivot and the footrest pivot. The outer side of the backrest pivot has a push-up inclined surface passing through a circular hole and a handlebar locking push block. The outer side of the footrest pivot also has a seat groove. The locking seat has an inner locking groove, and a gear is provided between the seat groove and the inner locking groove. The gear has a push-receiving inclined surface that cooperates with the push-up inclined surface, a handlebar locking stop pin that cooperates with the handlebar locking push block, and a stop pin spring that drives the handlebar locking stop pin to reset.

[0008] The stroller seat assembly described above is characterized in that the upper side of the handlebar locking pin has an arc-shaped surface and the other side has a locking surface, the area between the arc-shaped surface and the locking surface is a plane, and the lower part of the locking surface has a limiting step.

[0009] The stroller seat assembly described above is characterized in that the handlebar locking pin has buckles on both sides and the gear has a gear groove that engages with the buckles.

[0010] The stroller seat assembly described above is characterized in that the bottom of the handlebar locking pin is provided with a capacity cavity for the locking pin spring to be inserted, and the gear is provided with a limiting post for the locking pin spring to be engaged.

[0011] The stroller seat assembly described above is characterized in that the locking seat is further provided with a locking component and a fixing groove.

[0012] The stroller seat assembly described above is characterized in that the locking assembly includes a locking button disposed on a locking seat, a laterally movable locking block and a locking block spring disposed inside the locking seat, a button push block disposed inside the locking button, a locking block having a locking block inclined surface that cooperates with the button push block, and a locking seat having a locking groove that cooperates with the locking block.

[0013] The stroller seat assembly described above is characterized in that the folding switch assembly includes a folding locking block and a locking block return spring provided at the pivot joint of the backrest, an operating member provided on the backrest assembly, and a rope connecting the operating member and the folding locking block, and the foot pedal pivot joint is provided with a locking groove for the folding locking block to be engaged.

[0014] A stroller with the aforementioned stroller seat assembly is characterized in that the stroller includes a push rod assembly, a front wheel assembly is hinged to the lower part of the push rod assembly, a rear wheel assembly is hinged to the lower part of the push rod assembly via a rear connecting rod, a front connecting rod is hinged between the upper end of the front wheel assembly and the lower part of the rear wheel assembly, a push rod pivot seat is provided at the lower part of the push rod assembly, a front wheel pivot seat is provided at the upper end of the front wheel assembly and connected to the push rod pivot seat, and a locking part is provided on the inner side of the front wheel pivot seat to engage with a fixing groove on a locking seat.

[0015] The beneficial effects of this utility model are:

[0016] This utility model features a handlebar locking push block on the outer side of the backrest pivot joint, and a handlebar locking stop pin and a stop pin spring that drive the handlebar locking stop pin to reset on the inner side of the gear. This allows the handlebar locking stop pin to prevent the handlebar locking push block from rotating in the opposite direction after the seat assembly is folded, thus preventing the seat assembly from springing back after folding and achieving automatic locking. The backrest assembly and armrest assembly form an axial positioning effect, making the stroller seat assembly stable and fixed at a certain angle, which is convenient for independent placement.

[0017] When this utility model is installed on a stroller, during disassembly, pressing the locking button will push the button push block against the inclined surface of the locking block, and the locking block will move laterally and exit into the locking groove of the stroller. At this time, the seat assembly can be removed from the stroller along with the locking seat, which is convenient for transportation and storage, has a small storage space and low transportation cost, and can automatically fold in both directions.
