DETAILED DESCRIPTION
[0034] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will combine the drawings to make a detailed description of the embodiments of the utility model. It should be noted that, in the case of no conflict, the following described embodiments and the features in the embodiments can be combined with each other at will.
[0035] Many different embodiments or examples are provided below to implement the structure of the utility model.
[0036] Referring to Figures 1-11 , the utility model discloses a kind of combinable power bank, including power bank, the power bank includes shell 1, and the battery 2 of being set in shell 1, discharge plug 3 for connecting electric appliance is provided on shell 1, and charging socket 4 for connecting power supply, discharge plug 3 is connected with mobile phone charging port, charges mobile phone, charging socket 4 is used to connect power cord, charges power bank, discharge plug 3, charging socket 4 are electrically connected with the battery 2, one side of shell 1 is provided with first electric connection site 5, and the other side of opposite is provided with second electric connection site 6, first electric connection site 5, second electric connection site 6 specifically can be conductive sheet or conductive contact, first electric connection site 5 and second electric connection site 6 are adapted and electrically connected, when multiple the power bank is combined together, in adjacent two power banks, first electric connection site 5 on one power bank and second electric connection site 6 on another power bank contact to realize electrical connection, to realize electrical connection of the two power bank;For single power bank, first electric connection site 5, second electric connection site 6 on it have been electrically connected, it can be understood that, two power banks can be combined, and more power banks can be combined;Controller 7 is further provided in shell 1, and controller 7 is electrically connected with battery 2, first electric connection site 5, second electric connection site 6;Fixed connection structure is further provided on shell 1, and the fixed connection structure can be fixedly connected between power bank and power bank, that is, when multiple power banks are combined, adjacent two power banks can be fixedly connected by fixed connection structure.
[0037] Specifically referring to Figures 1-3 As shown in the utility model in some embodiments, discharge plug 3 and charging socket 4 are oppositely arranged on shell 1, and when multiple power banks are combined, charging socket 4 of first power bank is inserted with discharge plug 3 of adjacent second power bank, wherein controller 7 in last power bank is electrically connected with charging socket 4 on the power bank, and controller 7 on the rest power bank is disconnected with respective charging socket 4 (whether electrically connected, by controller self-control). Specifically referring to Figure 3As shown, there are four power banks, which are combined to form a large power bank. At this time, the first electrical connection position 5 and the second electrical connection position 6 of the adjacent two power banks are in contact to realize electrical connection. The first electrical connection position 5 of the left three power banks is in conduction with the second electrical connection position 6 of the adjacent power bank. The discharge plug 3 and the charging socket 4 of the adjacent two power banks are also plugged together. The controller 7 in the left three power banks can detect that the first electrical connection position 5 is in a conduction state. At this time, the controller will control the A position of the three power banks to be disconnected, that is, the charging socket 4 is disconnected from the battery 2 in the power bank. Thus, in the adjacent two power banks, the right power bank will not charge the left power bank through the plugged discharge plug 3 and charging interface 4. In addition, due to the presence of the controller 7, through program setting, the controller 7 can prevent the current in the battery 2 from flowing reversely through the line D and the controller 7. Thus, the adjacent two power banks will not charge each other through the line D and the line C, avoiding frequent charging and discharging between the power banks, which is beneficial to prolong the service life of the battery. In addition, due to the absence of frequent charging and discharging, it ensures that the power bank is not easy to heat, improving the safety. For the rightmost power bank, the first electrical connection position 5 is in an empty state. The controller 7 in the rightmost power bank detects that the first electrical connection position 5 is in an empty state, and controls the A position of the power bank to remain connected. Thus, the rightmost power bank can be externally connected to the charging line to realize normal charging of the rightmost power bank. In addition, the current of the external power supply flows through the C line, the controller 7 and the D line of each power bank to complete the charging of each battery. Figure 8As shown, has the line E, to take as the communication signal line, can be understood, E line can be incorporated into C line, through the program setting of controller 7, multiple power bank combination, controller can decide by one of power bank to charge mobile phone through communication, for example, according to the amount of power, the power bank with the most power supplies power to the mobile phone first, and the power bank with the second power supplies power to the mobile phone when the power bank with the most power is depleted. Therefore, the embodiment of the utility model can form a large power bank for charging mobile phone by electrically connecting multiple power banks through the first electric connection site 5 and the second electric connection site 6. Since the power bank in the embodiment of the utility model has the controller 7 and the first electric connection site 5 and the second electric connection site 6, when multiple power banks are combined to charge the mobile phone, the controller can be used to control (such as controlling the current direction), avoiding mutual charging between power banks through the discharge plug and the charging socket (high-power power bank charging low-power power bank) after multiple power banks are combined, thereby avoiding frequent charging and discharging of the power bank, which is beneficial to improve the service life and safety of the power bank. When multiple power banks are combined, only one power bank needs to be selected to be externally connected to the power supply, and the external power supply charges all power banks through the first electric connection site 5 and the second electric connection site 6, realizing simultaneous charging of multiple power banks at a time, avoiding the problem of charging multiple power banks separately in the prior art, greatly facilitating the user, and being beneficial to the popularization and application of small power banks.
