Description

Vehicle battery power supply device

technical field

The utility model relates to a power supply device, in particular to a vehicle battery power supply device suitable for two-wheeled electric vehicles. the

Background technique

With the vigorous development of science and technology, the use of electrical appliances has become an indispensable part of modern people's life, and the use of electrical appliances is directly provided by the power of the mains or batteries. But no matter what kind of power supply method, it is to meet the needs of users. Taking mobile phones as an example, the popularity of mobile phones makes it not surprising that everyone has a mobile phone. However, mobile phones are personal carry-on items, and batteries The power of the mobile phone is limited, and users do not necessarily stay indoors where they can be charged at any time. Therefore, it often happens that the mobile phone has no power and cannot be charged when people go out. Therefore, a car charger is produced to make the mobile phone. To achieve the purpose of charging at any time. Even so, the popularity and mobility of automobiles are still lower than electric vehicles, and mobile phone users who use two-wheeled electric vehicles as vehicles still cannot solve the situation that mobile phones have nowhere to charge, and need to be improved. the

Detailed ways

Below in conjunction with accompanying drawing, the structure of the present utility model is described in further detail:

Embodiment one

As shown in Figures 1 to 3, the vehicle-mounted storage battery power supply device of the present utility model comprises a vehicle-mounted storage battery 19, and a charging control circuit 14 is provided on the described vehicle-mounted storage battery 19, and the charging control circuit 14 is connected with the vehicle-mounted storage battery 19 respectively by cables The positive pole 191 is connected to the negative pole 192, and at least one plug-in end 141 is extended from the other end of the cable. In this embodiment, there are two plug-in ends 141, and the plug-in ends 141 are respectively connected to a plug-in terminal 11, The insertion terminal 11 is provided with a corresponding insertion portion 12 , and the insertion end 141 is inserted into the insertion portion 12 . The interface type on the plug-in terminal 11 in the utility model is consistent with the power input joint that needs charging equipment, for example two-hole or three-hole socket or USB slot all can be implemented. Preferably, the power input connector in this embodiment is set as a USB plug, and at the same time, the plug terminal 11 can be set as a USB slot; The terminal 141 is docked so that the plug terminal 11 can provide charging service for portable electrical appliances at any time. the

Moreover, as shown in FIG. 1 , an LED indicator light 13 may be provided on the plug terminal 11 , and a protective cover 15 is further provided on the top of the peripheral edge of the plug terminal 11 . the

As shown in FIG. 4 , the on-board storage battery 19 is combined with the electric vehicle 5 to provide the electric power required by the electric vehicle 5, and the plug-in terminal 141 extended by the charging control circuit 14 on the on-board storage battery 19 is pulled to the outside of the electric vehicle 5 and connected to the electric vehicle 5. The corresponding plug-in portion 12 of the plug-in terminal 11 is inserted and combined, and the plug-in terminal 11 can be fitted on the electric vehicle 5. The power cords of the user's various portable appliances can be connected to the plug-in terminal 11, so that the power of the vehicle battery 19 can be shared by the charging control circuit 14 to the portable appliances plugged into the plug-in terminal 11, as shown in Figure 5 , so that the battery of the portable electric appliance can supplement the electric quantity of the vehicle storage battery 19, so that the portable electric appliance itself has sufficient electric quantity, and can continue to use.
