Description
Technical Field
The invention relates to the field of charging cabinets, in particular to a charging cabinet for charging a shared charger.
Background
Along with the wide and quick popularization of mobile terminal at the crowd to and mobile terminal power consumption constantly increases, the user has the demand of charging at various occasions at any time, makes the business that charges precious lease the sharing through the sharing cabinet that charges on the market explodes for the user is not carrying under the circumstances that charges precious, rents the sharing and charges precious and charge mobile terminal
At present, a shared charger in the mainstream in the market is not provided with a special USB-A or USB-C port for charging a battery, but a specific metal contact is adopted to replace the ports, when the battery of the shared charger is exhausted or needs to be charged, the shared charger returns to a charging cabinet, and the metal contact of the shared charger is matched with a metal thimble of the charging cabinet for charging. In addition, the shared charger serves as a public shared resource and is placed in a shared charging cabinet in a public place, of particular concern to the safety and user experience of the shared charger, the operation of the shared charger requires monitoring the service life of the shared charger product itself (the number of cycles of use of the battery), the charging state of the battery (charging current, charging voltage, current temperature), the current aging capacity of the battery, etc., and monitoring whether the charger is in a rented state, therefore, when the shared power bank is inserted into the charging cabinet, data acquisition and control of the shared power bank (for example, in an abnormal state or in a flow state without normal payment, the charging output port is closed to prevent the product from being stolen from the cabinet and used 0, etc.) are required to be performed on various states of the shared power bank, and data interaction or communication is also performed between the shared power bank metal contact and the cabinet.
In order to realize carrying out the interaction of energy and data through metal contact and sharing treasured that charges, the cabinet that charges generally is provided with the metal thimble that matches with the metal contact in specific position, and the user returns the sharing treasured that charges to the rack after, the metal thimble contacts with the precious metal contact of sharing the treasured that charges, realizes charging and data interaction to the sharing treasured that charges.
Along with the increase of frequency of use, wearing and tearing can appear in metal thimble and metal contact, on the other hand, the user can let on hand sweat can remain on the contact owing to unconscious touch metal contact's custom, can lead to the contact to corrode for a long time, thereby lead to charging the communication of treasured and rack and charging badly, lead to the sharing to charge the treasured and can't normally be charged or the user can't rent the normal sharing of charging the treasured, lead to the sharing to charge the treasured and the cost of maintenance of charging the cabinet increases, bring very not good user experience.
In addition, in the process of returning the charge pal, a user is not free from reasons of poor returning habits and incorrect use modes, so that a metal thimble of the charging cabinet is prone to failure, the shared charge pal cannot be identified by the shared charging cabinet after entering the shared charging cabinet, on one hand, the shared charging cabinet cannot normally charge the shared charge, on the other hand, a background cannot correctly process actions of returning the shared charge pal by the user, a manufacturer needing the shared charge pal is required to manually check and take out the charge pal for maintenance and treatment, and the use and maintenance costs of products are also high.
In order to avoid these problems, common manufacturers of the shared charger generally increase the oxidation resistance by strengthening the metal contacts and the metal pins, such as gold plating treatment of the metal contacts and the metal pins; the metal thimble is reinforced, the gold plating layer is thickened and the like, but the measures only reduce the probability of problems, and the problem cannot be fundamentally solved when the cost is increased.
In addition, because the shared charger is frequently used, when returning to the charging cabinet, the shared charger needs to be charged quickly, the metal contacts often need to support the capacity of passing a large current, and when returning to the charging cabinet, a user needs to insert the shared charger in a positive and negative way in consideration of the returning randomness of the user, the shared charger can be identified by the charging cabinet, and the functions of the metal contacts, such as 6 contacts, 8 contacts or 2n contacts, are often symmetrically arranged, most of the contacts are used for the charging function, and the other contacts are used for the data communication function; the contact increases at double, and the metal thimble of the rack that charges also can cost-push up, in order to reduce because the unusual trouble of contact and thimble, through gilding or reinforcement means, the cost needs double again.
Therefore, a method is found, the problems of charging and data communication of the cabinet and the charging bank are solved, the rear-end maintenance cost is reduced as far as possible, and the method becomes an urgent affair for sharing the charging bank industry.
With the development of wireless charging technology and the popularization of wireless quick charging in mobile terminals such as mobile phones and the like, the application cost of wireless charging is greatly reduced, and with the development of wireless charging technology and standards, the wireless charging technology can meet the requirement of energy transmission and can also perform data interaction, such as the example; a transmitter and a receiver of a Qi protocol wireless charging system established by the International Wireless charging Union (WPC) adopt load modulation (ASK) and frequency modulation technology (FSK communication) to carry out communication and data transmission through an energy transmission coil while realizing wireless charging, further, the communication from a wireless charging receiving end (RX end) to a wireless charging transmitting end (TX end) is in an ASK mode, and the communication from the TX end to the RX end is in FSK communication, so that the current charging cabinet sharing a charging treasure can be reconstructed by adopting the wireless charging technology.
