Description

Technical Field

[0001] The present invention belongs to the field of mobile power rental, and particularly relates to a charging module of a mobile power rental device and a data transmission method between the charging module and a mobile power source. Background Art

[0002] Mobile power rental devices used in the mobile power rental industry usually need to be equipped with a charging module. The charging module is the main functional component for charging and data transmission of the mobile power rental device to the mobile power source. Currently, a relatively common solution on the market is to set elastic ejector pins on the charging module and metal contacts on the end face of the mobile power source. By contacting the elastic ejector pins with the metal contacts, the charging module can complete the charging and data transmission of the mobile power source.

[0003] The setting of the elastic ejector pins includes a power positive ejector pin and a power negative ejector pin necessary for charging, and also includes one or two communication ejector pins. The power positive ejector pin and the power negative ejector pin are in one-to-one correspondence with the positive and negative poles of the charging metal contacts of the mobile power source to complete charging. The communication ejector pins are also in one-to-one correspondence with the communication metal contacts of the mobile power source to complete data transmission. This data transmission method is theoretically fast in transmission speed and high in reliability. However, in actual use, since the metal contacts of the mobile power source are usually exposed outside the housing of the mobile power source, they are likely to be contaminated with foreign objects during the rental process. Once the metal contacts of the mobile power source are contaminated with foreign objects or there are foreign objects in the channel of the mobile power rental device blocking the normal contact between the ejector pins and the metal contacts of the mobile power source, it is very likely that the elastic ejector pins cannot effectively contact the metal contacts. In addition, long-term use of the mobile power rental device and the mobile power source will cause the ejector pins and the metal contacts to oxidize and age, resulting in poor contact between the ejector pins and the metal contacts, which will affect the charging module's reception of data sent by the mobile power source. The above two situations will both cause the mobile power rental device not to detect or recognize the returned mobile power source after the mobile power source is returned to the mobile power rental device, resulting in the background order not being automatically ended, continuous deduction of fees, customer complaints, and a bad impact on the market.

[0004] Moreover, since a large number of mobile power rental devices and mobile power sources that currently complete the charging and data transmission of the charging module to the mobile power source by contacting the elastic ejector pins with the metal contacts have been put on the market, all mobile power rental devices and mobile power sources on the market are of this form. Therefore, while solving the problem that the mobile power rental device cannot detect or recognize the returned mobile power source after the mobile power source is returned to the mobile power rental device, it is also necessary to consider that after the mobile power rental device and the mobile power source are improved, they should be compatible with the old mobile power rental devices and mobile power sources, so that the old mobile power sources can be used in the improved mobile power rental devices, and the improved mobile power sources can be used in the old mobile power rental devices.
