Description

Envelope structure of mobile device

The present invention relates to a mobile device, and in particular to an envelope structure of the mobile device.

People in China often use a protective film on the surface of new electronic products or cars to prevent the outer shell of the item from being scratched as much as possible, extend the service life of the item and maintain a better second-hand price. At the same time, users can also modify the appearance of the item by selecting protective films with different light transmittance, color or texture to make the item recognizable and personalized.

However, because the protective film is soft and thin, the structure corresponding to the protrusion of the object when it is wrapped is relatively fragile and easily hit by foreign objects, causing wear and damage. This problem is particularly serious for mobile electronic devices that people carry with them every day, because there are countless opportunities for mobile electronic devices to collide and rub with foreign objects, such as keys or coins when placed in pockets or bags. In addition, the protective film structure around the buttons and charging ports of mobile electronic devices is often worn, bulged or fallen off due to frequent force applied by fingers, scratches by nails, and repeated insertion and removal of plugs. When the protective film is damaged, it not only looks unsightly, but also loses its complete protective effect on the mobile electronic device it covers. The existing film structure of mobile electronic devices really needs to be improved.

One purpose of the present invention is to provide a membrane structure for a mobile device, which solves the problem of easy wear and damage of the membrane structure in the prior art by strengthening at least a partial structure of the protective film, thereby increasing the durability of the membrane structure and enhancing the protective effect on the mobile device.

In order to achieve the above-mentioned purpose, the envelope structure of the mobile device of the present invention includes a mobile device, a base film and at least one protective block. The mobile device is in the shape of a flat plate and has a front side, a back side and a peripheral surface connecting the front side and the back side. The base film is attached to the peripheral surface of the mobile device. The protective block is attached to at least a part of the surface of the base film and is not attached to the mobile device. The material of the protective block includes acrylic light-curing resin, which has a higher hardness than the base film, and can protect the base film within the covered range to prevent the base film from being worn by foreign objects, thereby enhancing the durability and protective function of the entire envelope structure.

The envelope structure of the mobile device of the present invention includes a mobile device, a base film and at least one protective block. The mobile device may be but is not limited to at least a part of the following electronic devices: a smartphone, a laptop, a tablet, a smart watch, a head-mounted display, a virtual reality/augmented reality wearable device. The mobile device is in the shape of a flat plate, having a front side, a back side and a peripheral surface, and the peripheral surface connects the front side and the back side. The base film is attached to the peripheral surface of the mobile device, and the material of the base film includes polyethylene terephthalate (PET) or polyethylene (PE). The protective block is covered on at least a partial surface of the base film and is not attached to the mobile device. The material of the protective block includes acrylic light-curing resin. Preferably, the acrylic light-curing resin is acrylic light-curing resin model 403246 produced by Japan PADICO Company.

As shown in FIG. 1 to FIG. 1B , a mobile device packaging structure 100 provided by the first preferred embodiment of the present invention is shown. The packaging structure 100 includes a smart phone 10, a base film 20, and a plurality of protective blocks 30, 31, 32, 33, 34. The smart phone 10 is in a flat plate shape, having a front surface 11, a back surface 12, and a peripheral surface 13, and the peripheral surface 13 connects the front surface 11 and the back surface 12 at the same time. The front surface 11 has a display screen, the back surface 12 has a lens, and the smart phone 10 has a jack 14, a pressure button 15, a cover 16, and a dial button 17 on the peripheral surface 13. For example, the jack 14 can be a power cord interface, the pressure button 15 can be a power button or a volume button, the cover 16 can be a SIM card storage mechanism, and the dial button 17 can be a mute mode switch.

In this embodiment, the base film 20 is attached to the peripheral surface 13 and the back surface 12 of the smart phone 10. In other embodiments of the present invention, the base film 20 may also be in the form of a frame with a through hole in the middle and attached only to the peripheral surface 13. The base film 20 is provided with an opening 21, a first through hole 22, a second through hole 23 and a third through hole 24 at positions corresponding to the insertion hole 14, the pressure button 15, the cover 16 and the dial button 17, so that the aforementioned components can function without being blocked by the base film 20. The base film 20 further includes a first covering film 25 and a second covering film 26, which are cut to correspond to the shapes of the pressure button 15 and the cover 16, respectively. The pressing button 15 passes through the first through hole 22, and the first coating 25 is disposed on the top surface of the pressing button 15. The second coating 26 is disposed on the surface of the cover 16.

The encapsulation structure 100 further includes four L-shaped protective blocks 30 and other protective blocks 31, 32, 33, 34 of various shapes. As shown in FIG1A , the four protective blocks 30 cover the surface of the base film 20 and are arranged on the four corners of the peripheral surface 13 of the smart phone 10 through the base film 20, so as to strengthen the structure of the base film 20 at the corners of the smart phone 10 and enhance the protection of the corners of the smart phone 10. The shape of the protective block 31 corresponds to the shape of the pressure button 15 and is arranged on the first coating 25, as shown in FIG2 , so as to strengthen the structure of the first coating 25 and enhance the protection of the pressure button 15. Similarly, the shape of the protective block 32 corresponds to the shape of the cover 16 and is disposed on the second coating 26 to strengthen the structure of the second coating 26 and enhance the protection of the cover 16. The protective block 33 is annular and is located outside the opening 21 of the base film 20 to strengthen the structure of the base film 20 around the plug hole 14 and prevent the plug from damaging the base film 20 around the opening 21.

Please refer to Fig. 3 and Fig. 1B together. The guard block 34 is annular and is disposed outside the third through hole 24. As shown in Fig. 3, a top surface 341 of the guard block 34 is located on an imaginary plane P, and the dial button 17 does not pass through the imaginary plane P. In this way, the protective block 34 can protect the dial button 17 and prevent the dial button 17 from being hit by unnecessary foreign objects. For example, when the user inserts the smart phone 10 into a case (not shown) or pulls it out of the case, the case can prevent the dial button 17 from being accidentally turned. In addition, the protective block 34 can also strengthen the structure of the base film 20 around the dial button 17 to prevent the base film 20 from being damaged by frequent turning of the dial button 17.

It is worth noting that all the aforementioned protective blocks 30, 31, 32, 33, 34 do not directly contact the surface of the smartphone 10. The manufacturing process is that after the base film 20 covers the smartphone 10, acrylic light-curing resin is applied to a local portion of the base film 20 and then cured by ultraviolet light. In this way, when the user wants to sell the second-hand smartphone 10, the protective blocks 30, 31, 32, 33, 34 can be easily removed from the smartphone 10 along with the base film 20.
