Shared power bank

Abstract

The invention relates to the field of power banks, in particular to a shared power bank, and the shared power bank comprises a main control circuit board; a main control unit, a wireless charging function module, a power management function module and a sensor switch function module are arranged on the main control circuit board; the wireless charging function module comprises a wireless chargingtransmitting and receiving integrated coil module. The invention has the beneficial effects that a wireless charging technology is adopted, a user can place the shared power bank on the wireless charger for wireless charging, electric quantity is supplemented, and the user can also use an intelligent terminal supporting wireless charging for wireless charging; the electric quantity state and the sign information of the shared power bank can be transmitted to the wireless charging device in a wireless mode.

Description

technical field [0001] The invention relates to the field of charging treasures, in particular to a shared charging treasure. Background technique [0002] Shared power bank refers to the charging rental equipment provided by the enterprise. Users use their mobile devices to scan the QR code on the screen of the device and pay a deposit to rent a power bank. After the power bank is successfully returned, the deposit can be withdrawn at any time and returned to the account. Shared charging Treasure’s borrowing process can be roughly divided into four steps, scanning the code-registering-paying-lending. Generally, the whole process takes less than 3 minutes. The return method is similar to that of shared bicycles. Users can return them to the nearest location on the official account platform according to the GPS location of the power bank. [0003] At present, the mainstream shared charging treasures on the market do not have dedicated USB-A or USB-C ports for charging the ba...

Problems solved by technology

[0005] Shared power bank metal contacts, with the increase in frequency of use, on the one hand, the metal contacts will wear out, on the other hand, due to the user's habit of unconsciously touching the metal contacts, the sweat on the hands will remain on the contacts. As a point, long-term contact corrosion will lead to poor communication and charging between the power bank and the cabinet, resulting in the failure of the shared power bank to be charged normally or the failure of the user to rent a normal shared power bank, resulting in the failure of the shared power bank and the charging cabinet. Increased maintenance costs, resulting in a very bad user experience

[0006] On the other hand, in the process of returning the charging treasure, the user will inevitably have bad returning habits and incorrect use methods, which may easily lead to failure of the metal thimble of the charging cabinet. After the shared charging treasure enters the shared charging cabinet, there is no way to share the charging cabinet. Identifying the power bank, on the one hand, there is no way to charge the shared charging normally, and on the other hand, the background cannot correctly handle the action that the user has returned the shared power bank. The manufacturer of the shared power bank needs to manually check and take out the power bank. Repair and disposal, product usage and maintenance costs are also high;

[0007] In order to avoid these problems, manufacturers of shared power banks generally strengthen the process of metal contacts and metal thimbles, such as gold-plated metal contacts and metal thimbles, to improve oxidation resistance; metal thimbles are reinforced, thickened gold-plated layers, etc., but These measures only reduce the probability of occurrence of problems, while increasing costs, there is no way to fundamentally solve this problem;

[0008] In addition, due to the high frequency of use of the shared power bank, when returning it to the charging cabinet, it needs to be charged quickly. The metal contacts often need to support the ability to pass a large current, and when the user returns the power bank to the charging cabinet, Considering the arbitrariness of the user's return, it is required to insert and return the shared power bank in the front and back, and the charging cabinet can be identified. It is often necessary to set the function of metal contacts symmetrically, such as 6 contacts, 8 contacts or 2n contacts. Most of the contacts are used for the charging function, and some are used for the data communication function; the number of contacts is multiplied, and the cost of the metal thimble of the charging cabinet will also increase. In order to reduce the abnormal failure of the contacts and thimbles, gold plating or reinforcement means, the cost will double again;
