Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of general USB flash disk, and this general USB flash disk as shown in Figure 1, 2, comprising: standard USB interface 101, micro usb 1 02 and storer; Wherein, micro USB interface comprises: GND, ID, data line are negative, data line just with power supply just.
Embodiment one
The present embodiment provides a kind of USB flash disk, and this USB flash disk as shown in Figure 3, comprising: standard USB interface 101, micro usb 1 02, storer, MCU 103, power supply 106 and two arrow signal lamp groups 105; Wherein,
Standard USB interface 101 is connected with No. 1 pin of MCU103, and micro usb 1 02 is connected with No. 2 pins of MCU103; One end of storer is connected with standard USB interface 101, the other end is connected with micro usb 1 02, power supply 106 is connected with the power interface of MCU103, and two arrow signal lamp groups 105 are connected with No. 3 pins of MCU103 and No. 4 pins respectively, and the arrow of two arrow signal lamp groups is contrary.
The technical scheme that the utility model provides adds micro USB interface, USB flash disk is made to use on mobile phone or panel computer very easily like this, in addition, the flow direction of data for convenience of user to watch, also be provided with two arrow signal lamp groups that arrow is contrary, like this when USB flash disk sense data and write data, can be watched very easily by signal lamp group, adding users is experienced.
Optionally, above-mentioned power supply 106 comprises: solar cell 113, solar battery group structure as shown in Figure 4, comprising:
Multiple condenser 1131, be provided with multiple astigmatoscope 1132 between multiple condenser 1131, solar panel 113 also comprises: be arranged on the solar panel 1133 under multiple condenser 1131 and multiple astigmatoscope 1132.
Wherein, above-mentioned condenser concavees lens are specifically as follows convex lens, and above-mentioned astigmatoscope are specifically as follows convex lens.
Optionally, above-mentioned arrow signal lamp group comprises: multiple LED, multiple resistance and multiple triode, the circuit structure of the plurality of LED as shown in Figure 5, wherein, in Fig. 5 " 3/4 represents No. 3 or No. 4 pins connecting MCU, and this circuit structure comprises:
