Description

  The present invention relates to a protective case provided with a detachable shock absorber for a portable electronic device. Different protective shock absorbers can be attached to the protective case depending on the situation, and the portable electronic device can always be appropriately protected by the protective case under various impact situations. In particular, the present invention relates to a portable electronic device that protects the portable electronic device by bounce (bounce) that converts the impact kinetic energy into elastic potential energy when the portable electronic device falls on the ground or receives an impact. The present invention relates to a protective case provided with a detachable shock absorber for a device.

With advances in technology, portable electronic devices are becoming increasingly thinner and lighter. Therefore, the built-in components and the electronic circuit are incorporated in a more compact manner. However, such complex and highly compact portable electronic devices cannot withstand strong physical impact forces.

  In order to address the above problems, protective cases are often used to protect portable electronic devices. However, current protective cases are made of rigid metal or plastic, and when shocked, they absorb the shock and only deform or break, transforming the impact kinetic energy into elastic potential energy storage It is something that does not. If the impact energy exceeds the absorption capacity of the protective case, excess impact energy propagates to the portable electronic device and damages the electronic device.

  Other conventional protective cases with shock absorbers are manufactured in one piece and only have a certain effect in order to convert impact kinetic energy into elastic potential energy storage. However, the impact kinetic energy generated from the portable electronic device falling on the outdoor ground is greatly different in strength from the impact kinetic energy falling on the indoor floor. In order to properly protect in various impact situations, the user has to purchase various protective cases with different protection capabilities to protect the portable electronic device, which is inconvenient and wasteful.

Therefore, the protective case having the detachable shock absorber according to the present invention not only sufficiently protects the portable electronic device but also improves convenience and economy.

  While numerous features and advantages of the present invention have been described, along with the detailed structure and function of the present invention, the disclosed contents are for the purpose of technical description of the invention only. Within the technical scope of the invention as defined in the claims for utility model registration, it is possible to arrange and change details, in particular shape, size and parts.

The connecting portion covers the entire periphery or part of the receiving portion. Preferably, the length of the receiving part that is often covered by the connecting part is not less than ½ of the total length of the receiving part.

  Preferably, the receiving part can be formed in various shapes, such as spherical, columnar and conical, and is complementary to the shape of the connecting part. The cone-shaped receiving part is inclined toward the corner part of the housing.

  Preferably, the shock absorber protrudes from the side wall portion of the housing. In another embodiment of the present invention, the housing has a bottom wall coupled to the side wall, and the cavity of the housing is provided by the side wall and the bottom wall.

Protects portable electronic devices from strong impact forces.

  A desirable shock absorber with an elastic ratio of 60% has a conversion efficiency from impact kinetic energy to elastic potential energy of 60%. For example, after the first bounce, 60% of the impact kinetic energy is converted to the elastic potential energy of the shock absorber, and 40% is attenuated as other forms of energy. The second bounce thereafter converts the remaining 60% of the initial impact kinetic energy into another 60% elastic potential energy. Therefore, after the first bounce, the impact kinetic energy remains at 60% of the initial impact kinetic energy, and after the second bounce, the impact kinetic energy further decreases, and only 36% of the initial kinetic energy remains and repeats the bounce. The impact kinetic energy is very small and the portable electronic device is protected.

  Preferably, the housing of the protective case has at least one notch formed in the side wall portion and the bottom wall portion of the housing, and is provided on the bottom and side portions of the electronic device for ensuring the convenience of operation of the electronic device.
