Description

A combined connector

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 2, 2023, with application number 202322953638.4 and invention name “A combined connector”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field related to new energy two-wheeled vehicles, and more precisely to a combined connector. Background Art

[0003] New energy two-wheelers offer advantages such as energy conservation, environmental protection, and low-effort riding, leading to an increasing number of people choosing them as a means of transportation. Safely and quickly connecting to a power source is a key development for these vehicles. To reduce charging times for these vehicles, researchers are exploring battery swapping. This approach involves replacing a depleted battery with a fully charged one, which is then recharged. This approach effectively reduces the time between uses and significantly improves the user experience.

[0004] The battery and the drive system of the new energy two-wheeled vehicle are connected through a battery exchange connector. The male and female ends of the existing connectors mostly adopt a direct plug-in connection method, which is fixed by squeezing the contact position after alignment. In order to ensure that the connector will not be disengaged due to vibration during use, the insertion force required for the male and female ends to be locked is relatively large. If the user is not aware of the complete intermatching and does not use a lot of force to align the ends during insertion, it is easy to cause the connection of the connector to be unstable and the contact at the connection position to be poor. Long-term poor contact will cause damage to the connector, reduce the service life of the connector, and affect the safety of the new energy two-wheeled vehicle.

[0005] In summary, this field needs to improve the connectors of existing new energy two-wheeled vehicle batteries to ensure that the male and female ends are firmly connected after alignment and mating, while being convenient for users to operate.
