Description

  The present invention relates to a bounding case of a portable electronic device that can convert kinetic energy at the time of impact to elastic potential energy when the portable electronic device falls on the ground and jumps up. More specifically, in the present invention, the bounce type case absorbs the impact by converting the kinetic energy at the time of impact of the portable electronic device into the elastic potential energy of the elastic member, and the change is made while the impact force repeatedly bounces. It is related with the bound type case of a portable electronic device and the bound type portable electronic device which decrease gradually through.

  With the advance of technology, portable electronic devices have become thinner and lighter, and internal components and electronic circuits have become more compact. However, such highly functional and ultra-compact portable electronic devices cannot withstand strong impacts.

  In order to prevent the above situation, a protective case for protecting the portable electronic device is often used. However, the current protective case is made of hard metal or plastic and absorbs the impact rather than converting the kinetic energy at impact to the accumulation of elastic potential energy. It just breaks. Once the impact energy exceeds the amount of energy that can be absorbed by the protective case, the excess impact energy is transmitted to the portable electronic device, damaging the device.

  In view of the problem that a conventional protective case cannot protect a portable electronic device from a strong physical shock, the object of the present invention is to use the elastic potential energy of the elastic member as the kinetic energy at the time of impact of the portable electronic device. It is to provide a bounce-type case that turns into accumulation.

In order to solve the above problems, the present invention is a bounding case for a portable electronic device,
The front,
A bottom formed on the opposite side of the front surface;
A plurality of sidewalls formed between the front surface and the bottom and interconnected to form a plurality of corners;
A housing having a cavity surrounded by the front surface, the bottom portion and the side wall;
Provided is a bound type case having a plurality of elastic members respectively disposed at corners of the housing and having an elastic modulus higher than 40%.

  According to the present invention, the elastic member of the bound type case has an outer surface protruding from the front surface, the bottom portion, and the side wall. When the portable electronic device housed in the bound type case falls on the impact surface, the elastic member of the bound type case becomes the first contact point with respect to the impact surface. That is, the portable electronic device is floated on the impact surface by the elastic member. For this reason, neither the housing of the bound type case nor the internal portable electronic device directly hits the impact surface. Furthermore, the elastic member arranged at the corner of the housing converts the kinetic energy at the time of impact to the elastic potential energy of the elastic member.

  In the specification, the expression “elastic member arranged at each corner of the housing” is not intended to be limited to the case where the elastic member is arranged at the exact center of the corner. For example, the elastic member may be disposed close to or slightly away from the center of the corner, and such a case is included in the scope of the case where the elastic member is disposed at the corner of the housing.

  When measured by the Bayshore rebound resilience ASTM D2632, the elastic modulus of the elastic member is greater than 40%. When an electronic device placed in a bound type case is accidentally dropped on the ground, the elastic member of the bound type case converts most of the kinetic energy at the time of impact to the elastic potential energy of the elastic member and jumps once In addition, a small part of the impact energy can be dissipated, whereby the portable electronic device can be protected from a strong impact force.

  Correspondingly, an ideal elastic member with an elastic modulus of 60% converts impact kinetic energy into elastic potential energy with a conversion efficiency of 60%. For example, after the first bounce, 60% of the impact kinetic energy is converted to the elastic potential energy of the elastic member, and 40% is dissipated as other forms of energy. In the second bounce, the remaining 60% of the initial impact kinetic energy is further converted to 60% elastic potential energy. Therefore, after the first bounce, 60% of the initial impact kinetic energy remains, and after the second bounce, the kinetic energy further decreases, leaving only 36% of the initial impact kinetic energy. By repeating, the impact kinetic energy is reduced to the minimum, and the portable electronic device can be protected.

  The elastic member preferably protrudes from any one of the side wall, front surface, and bottom of the housing, and more preferably protrudes from all the side walls, front surface, and bottom of the housing. When the portable electronic device is stored in the bound type case, the portable electronic device is lifted by the elastic member and is protected from a direct impact.

  The housing preferably has an outer shape that matches the shape of the portable electronic device to further enhance protection.

  The front and bottom are rectangular, and the bound case has four side walls formed between the front and bottom of the rectangle, the four side walls are interconnected, and four corners are formed between them. Preferably it is. The bound type case has four elastic members arranged at the corners of the housing.

  The housing of the bound type case is harder than the elastic member, is not deformed by a physical impact, and can be a reliable support for securely storing the portable electronic device without being detached from the portable electronic device. preferable.

  The elastic member is preferably made of a material selected from the group consisting of polyurethane, vulcanized polybutadiene, and natural rubber.

  The housing preferably further includes an elastic member disposed on one of the side walls. Such an elastic member can enhance protection of the side surface of the portable electronic device. More specifically, when the portable electronic device is large, it is more effective to protect the side surface of the portable electronic device from impact.

  The elastic member is preferably a sphere. Here, the elastic member of the sphere includes those arranged at the corners and those arranged at the side walls.

  The housing of the bound type case preferably further has a notch corresponding to the button of the electronic device formed on the side wall for convenience when operating the electronic device.

  Preferably, the bottom of the housing has a back surface on the opposite side of the cavity, and the bound type case further includes a buffer member protruding from the back surface. The shock-absorbing member can prevent the back surface of the portable electronic device from receiving an impact. It is preferable that the buffer member has a conical top shape.

  In order to achieve the above object, the present invention also provides a bound type portable electronic device comprising the bound type case and a portable electronic device accommodated in the cavity.

  The bound type case can accommodate various portable electronic devices such as a mobile phone and a tablet computer to form a bound type portable electronic device.

  The buffer member is preferably formed in the shape of a conical top, and is disposed on a common gravity axis defined by the portable electronic device and the bound type case. With such a shape, the bounce-type case with the buffer member has a plus-alpha effect in entertainment and distraction.

  To summarize the technical features of the present invention, the bounded case / bounded portable electronic device can convert the impact kinetic energy of the portable electronic device into the elastic potential energy of the elastic member, and thereby housed inside It is possible to prevent the portable electronic device being damaged from being damaged by a strong physical shock. This conversion provides complete protection of the portable electronic device as impact kinetic energy is gradually reduced and minimized with each bounce.
