Description

Portable electronic device

The present invention relates to an electronic product, and more particularly to a portable electronic device.

With the development of electronic integration technology, many products are moving toward miniaturization and portability. Such as current mobile phones, consumer electronics such as MP3, MP4.

When people use portable electronic products, they often accidentally fall to the ground or collide with other objects. Such accidents may cause damage to the internal functional circuits of electronic devices, but maintenance personnel do not know the scene of such things happening. Lead to maintenance difficulties.

In view of this, it is necessary to provide a portable electronic device that is convenient for maintenance.

A portable electronic device includes a body, and the body is provided with a piezoelectric element for generating a corresponding electrical signal according to an external force received. The portable electronic device further includes: a processing module and a storage module, The processing module is connected to the piezoelectric component, and is configured to convert the electrical signal generated by the piezoelectric component into a digital message indicating that the portable electronic device is recorded by collision, and save the digital information in the storage module.

When the portable electronic device is dropped or collided, the drop or collision will be recorded. If the portable electronic device fails, the maintenance personnel can use the digital information stored in the portable electronic device to assist in the fault cause determination and maintenance.

FIG. 1 is a perspective structural view of a portable electronic device according to a preferred embodiment.

2 is a schematic view of the internal structure of a preferred embodiment.

The present embodiment provides a portable electronic device that can automatically record a message that it has been dropped.

Please refer to FIG. 1 , which is a perspective structural view of the portable electronic device 10 . The body 100 of the portable electronic device 10 has a flat rectangular parallelepiped shape, and the four pairs of corners of the body 100 are respectively covered with a buffer portion made of an elastic material. 102. Each buffer portion 102 simultaneously covers the four surfaces involved in the pair of corners.

Please refer to FIG. 2 , which is a schematic diagram of the internal structure of the portable electronic device 10 . The piezoelectric element 104 is disposed inside each buffer portion 102 of the portable electronic device 10 , and the piezoelectric element 104 is used for sensing the buffer portion. The force acting on the piezoelectric element 104 when the deformation is 102, and corresponding electrical signals are generated according to the force.

The portable electronic device 10 further includes a processing module 106, a storage module 108, an alarm module 110, and an output interface 112.

The processing module 106 is connected to the piezoelectric element 104 inside each buffer portion 102 for converting the electrical signal generated by the piezoelectric element 104 into a digital message and storing it in the storage module 108. The digital message includes: collision location information, collision number message, collision light message, and the like. The collision site information is identified by electrical signals generated by piezoelectric elements 104 at different locations. The collision number information is obtained by accumulating the number of electrical signals generated by the piezoelectric element 104, that is, each time the electrical signal generated by the piezoelectric element 104 is detected, the number of collisions recorded in the storage module 108 is incremented by one, and the initial collision number message is zero. The collision light weight signal can be generated by the electrical current generated by the piezoelectric element 104 or The difference in voltage magnitude is obtained.

The alarm module 110 is also connected to the piezoelectric element 104 inside each buffer portion 102 for sending an alarm message, such as an audible alarm or a illuminating alarm, in response to an electrical signal generated by the piezoelectric element 104. In other embodiments, the alarm module 110 can also be connected to the processing module 106. When the processing module 106 detects the electrical signal generated by the piezoelectric element 104, the alarm module 110 is activated to alarm.

The output interface 112 is connected to the storage module 108 for reading the digital information in the storage module 108 to assist the maintenance personnel in determining the cause of the failure and the maintenance work.

It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
