Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram provided in the embodiment of the present invention, as shown in fig. 1, including: the device comprises a box body A, a box door B, a photoelectric energy collecting device 1, a piezoelectric energy collecting device consisting of an electromagnetic sensor 2 and a piezoelectric sensor 3, an electric energy collecting device 4, a detection circuit 5, a first switch 6, a second switch 7, an interactive component 8 and a processor.

Referring to the schematic structural diagram shown in fig. 1 and the schematic circuit structural diagram shown in fig. 2, the box body a is a cube and has six external vertical surfaces, and the photoelectric energy collecting device 1 is mounted on the top surface or the rear, left and right side surfaces of the box body a in a patch or embedded manner to sense an external light source and convert light energy into electric energy. The output end of the photoelectric energy collecting device 1 is connected with a first switch 6 through a circuit, and the first switch 6 is communicated with the electric energy collecting device 4.

The electromagnetic sensor 2 is installed on the inner wall of the box body A, and the receiving end of the electromagnetic sensor is installed on a bearing for hinging the box body A and the box door B. When the box door B is opened, the bearing rotates to generate kinetic energy, and the electromagnetic sensor 2 is used for converting the kinetic energy into electric energy. The output end of the electromagnetic sensor 2 is connected with a second switch 7 through a circuit, and the second switch 7 is communicated with the electric energy collecting device 4.

The piezoelectric sensor 3 is preferably installed on the inner wall of the box body a, receives in real time a pressure signal generated by deformation due to contact with the bottom and the inner side surface of the box body a when the level of the secured object in the box body a moves, and converts the pressure signal into electric energy. The piezoelectric sensor 3 is also arranged in the interlayer of the box body A close to the cavity of the box body A and arranged on the surface of the box door B, so as to realize the purpose of receiving pressure signals from multiple directions. The output end of the piezoelectric sensor 3 is connected with a second switch 7 through a circuit, and the second switch 7 is communicated with the electric energy collecting device 4. The output end of the electric energy collecting device 4 is connected with the detection circuit 5 for continuously supplying power to the detection circuit 5.

The photoelectric energy collecting device further comprises an interaction assembly 8, wherein the interaction assembly 8 is installed on the outer surface of the box body, a processor is embedded in the interaction assembly 8, a control command output pin of the processor is connected with a setting receiving end of the photoelectric energy collecting device and a setting receiving end of the piezoelectric energy collecting device, and is used for receiving a setting instruction of a user and switching a circuit path according to the setting instruction.

It is right to combine specific use scene now the utility model discloses technical scheme explains:

the user inputs a setting instruction to the interactive assembly, and the setting instruction is three types: the method is characterized in that only the photoelectric energy collecting device is adopted to collect electric energy, only the piezoelectric energy collecting device is adopted to collect electric energy, and the automatic switching mode is adopted to collect electric energy. In the automatic switching mode, when the photoelectric energy collecting device senses a light source, the first switch 6 is communicated; when the piezoelectric energy collecting device senses the structural deformation, the second switch 7 is connected.

The interactive component is an electronic hardware element such as a button, a display screen or a Bluetooth receiver and the like capable of receiving clicking, touching, sensing or remote instructions.

When the safe is placed in an active environment (outdoor or indoor lighting environment), the photovoltaic energy collection device 1 collects external illumination (lighting light or sunlight), so as to continuously charge the electric energy collection device 4. When the sunlight intensity is strong, the charging speed is fast, and when the sunlight intensity is relatively weak like an illumination tube, the charging speed is relatively slow. The device does not need to replace a new battery, and only needs to be bright. The electric energy collection device 4 may be installed outside the box a in an external form, or may be installed inside the box a when the box a leaves the factory.

When the safe is moved to a dark room, the photovoltaic energy collecting device 1 cannot provide enough electric energy for a subsequent circuit to use due to insufficient illumination, and the built-in piezoelectric energy collecting device is used for supplying power. Specifically, when the box body a is moved, the piezoelectric energy collecting device senses a pressure signal generated by micro deformation inside or outside the box body a caused by vibration generated during the movement in real time, and converts the pressure signal into an electric signal to be transmitted to the photoelectric energy collecting device 1 through the second switch 7.

When the box door B is opened, the bearing rotates and also generates deformation, and the deformation is captured by the piezoelectric collecting device and converted into an electric signal which is transmitted to the photoelectric energy collecting device 1 through the second switch 7.

The photoelectric energy collecting device 1 stores the received electric signal and continuously supplies power to the detection circuit 5 for detecting whether the opening of the box door B is normal or not, so that whether the opening/closing of the box body A is normal or not can be recorded in real time.

Therefore, the box A is charged temporarily, the detection circuit 5 can detect whether the box A is opened normally or not, and the opening times of the box A and other information can be recorded.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
