Technical Field

[0001] The present invention relates to the technical field of bicycles, and in particular to a crankset locking device for a shared bicycle and a locking and unlocking method thereof. Background Art

[0002] As a new product of the sharing economy, shared bicycles are widely favored due to their advantages of being able to be picked up and dropped off at any time and parked as soon as you go, playing a positive role in solving the "last mile" of travel. With the rapid development of shared bicycles, "negative externalities" such as high-density spatial and temporal aggregation and disorderly parking of vehicles are becoming increasingly serious, and relevant parties are urgently required to further strengthen management.

[0003] The capacity scheduling and standardized placement of shared bicycles are numerous and wide-ranging. The temporal and spatial characteristics of demand and the service sharing model determine that user self-organization management is difficult to meet demand. It requires dedicated personnel to schedule movement and standardized placement, which consumes a lot of manpower and material resources.

[0004] At present, shared bicycles use the active wheel (rear wheel) lock / unlock mode. The bicycle is locked by default, and users can only unlock it and ride it after scanning the code. The on-site dispatch and standardized placement of shared bicycles are management needs rather than user needs. The movement process involves a large number of vehicles, a short moving distance, and high timeliness requirements. The default locking of the wheels makes it difficult to manage and move the vehicle by pushing and rolling. Moving the vehicle by manual lifting and placing is time-consuming and labor-intensive, which seriously reduces the efficiency of management work. Therefore, there is an urgent need for a locking device to achieve joint management by all people, without the need to hire additional management personnel to place the bicycles, thereby greatly reducing the operating costs of shared bicycle companies.

[0005] After searching the published patents, the following patents were found to be most relevant to this technical solution:
