Description

TECHNICAL FIELD

[0001] The utility model relates to a scooter seat armrest structure and belongs to the technical field of scooters. BACKGROUND

[0002] At present, people use various devices such as scooters to facilitate the movement and activities of people with difficulty in movement. Although the scooter provides convenience for users to move for a long distance, it cannot be folded for storage, so that the scooter occupies a large space when not in use, causing great inconvenience in transportation and storage.

[0003] A folding scooter is disclosed in Chinese patent application CN204197172U, which comprises a backrest frame, a seat frame, a lower frame, two rear wheel assemblies, two front wheel assemblies and an armrest. The armrest and the seat frame are hingedly connected to the backrest frame from top to bottom. The two front wheel assemblies are connected to the lower frame. A sliding guide is arranged between one end of the seat frame and each rear wheel assembly. A sliding block is slidably connected to the sliding guide. The sliding block is hingedly connected to the lower end of the backrest frame and is also hingedly connected to the lower frame. Alternatively, the lower end of the backrest frame is hingedly connected to the sliding block, and the lower end of the backrest frame is also hingedly connected to the lower frame. Alternatively, the lower frame is hingedly connected to the lower end of the backrest frame, and the lower frame is also hingedly connected to the sliding block.

[0004] The seat armrest of the above-mentioned scooter adopts a hinged folding structure. In actual use, some groups of users need the seat armrest, but some groups of users do not need the seat armrest. In the production process, the seat armrest produced by using a complex hinge structure directly affects the overall appearance when disassembled to meet the needs of some customers. Moreover, the disassembly efficiency is low, which greatly affects the production efficiency. The cost of producing a scooter without a seat armrest by opening a mold is further increased. SUMMARY

[0005] The utility model aims at providing a scooter seat armrest structure, which solves the problems of affecting product appearance, low production efficiency and high production cost in the prior art.
