Description
The present invention relates to a mobile case having a power generating device, and more particularly, to a mobile case having a power generating device. More particularly, the present invention relates to a mobile case in which a power generating device is internally provided to generate electric power by using an external force, And a mobile device equipped with a power generation device for protecting mobile electronic devices such as mobile phones and tablet PCs.
Nowadays, many people are using mobile phones, and in the case of smart phones, mobile phones can perform not only calls but also surfing the Web, listening to music or playing games.
Such frequent use of mobile phones through web surfing, music appreciation, or games consumes the battery capacity of the mobile phone in a short period of time. If the mobile phone battery capacity is exhausted, the mobile phone can not be used until the battery is recharged.
Therefore, the user of the mobile phone carries a spare battery, and the battery is used after the battery capacity of the mobile phone is exhausted. However, there is a problem that the user feels troublesome to carry the battery at all times.
Further, instead of the battery, the mobile phone can be charged using an adapter even in an automobile or the like, but there is a problem that the battery can not be charged if there is no power source device during frequent outdoor activity or movement.
In order to solve such a problem, an automatic charging device which can be integrated with a mobile phone is required. However, if such a charging device is embedded in a mobile phone, problems may arise such that the volume of the mobile phone becomes large. Therefore, there is a mobile phone case as an alternative device.
Conventionally, a mobile case such as a mobile phone case is generally made of a polymer material. In most cases, the mobile phone carries only a shock-preventing function and a design function for promoting the purchase motivation of the customer, There is a problem that the problem of dealing with exhaustion can not be solved.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a mobile device, It is an object of the present invention to provide a mobile case having a power generation device for protecting a mobile electronic device such as a PC.

At this time, the first vibration assisting device and the second vibration assisting device may be made of magnets.
In addition, the first vibration assisting device and the second vibration assisting device may be made of mutually different electrodes.
The first vibration assist device may include a vibration guide member for amplifying vibrations due to the external force applied from the outside and transmitting the amplified vibration to the second vibration assist device.
The power generation device may include a support column protruding from a surface of the housing, a first lower conductive plate provided at an upper end of the support column, and a piezoelectric element module provided on an upper surface of the first lower conductive plate. have.
The first lower conductive plate may have a cantilevered shape with one longitudinal end portion fixed to the upper end of the support column, and the first vibration assisting device may be provided at the other longitudinal end portion of the lower conductive plate.
The piezoelectric element module may include a first piezoelectric element protruding from the upper surface of the first lower conductive plate, a first upper conductive plate provided on the upper surface of the first piezoelectric element, and a second upper conductive plate provided on the upper surface of the first upper conductive plate. And a second insulating plate.

The mobile case equipped with the power generation device of the present invention has the following effects.
First, the mobile case is vibrated by an external force applied from the outside, and accordingly, the piezoelectric element module vibrates, so that electric power is generated and the battery of the mobile device can be charged directly or indirectly.
Second, the vibration assisting device and the vibration inducing member accelerate and increase the vibration caused by the external force, so that it is possible to produce relatively large electric power even in a small movement of the mobile case.
Third, compared with the piezoelectric element module formed as a single layer through the multilayered piezoelectric element module structure, an increased power can be produced.
Fourth, even if the user does not generate the external pressure by vibrating the mobile case arbitrarily, the charging using the power generator is facilitated through the vibration generated when the user is walking or jogging or when the vehicle is running.

Piezoelectric phenomenon refers to a phenomenon in which positive and negative electric charges appear at both ends of the crystal plate in proportion to the external force when a certain kind of crystal plate is pressurized in a certain direction.
The electromotive force appearing on a single crystal plate is weak, but the amount of electromotive force is increased when multiple sheets are stacked while inserting metal foil. In addition, if the mechanical vibration or electrical vibration applied to the crystal plate has a natural frequency according to the type and mass of the crystal plate, resonance occurs to generate more powerful electromotive force.
Here, the resonance phenomenon refers to a phenomenon in which vibration is amplified when the frequency of external forced oscillation is equal to or similar to the natural frequency of a structure or a material.
