This application claims the priority of the patent application number US 16,724,315 filed in the United States on December 22, 2019, the entire content of which is incorporated herein by reference.

Field of invention

The present invention relates to a vertical protective cover for portable equipment, in particular to a protective cover for reducing the probability of screen breakage due to equipment falling or other external forces by strengthening the protection of the corners of the screen of the device.

Background technique

The most common and commonly used protective cover for portable devices, of course, is a mobile phone protective cover, which is usually made of Thermoplastic Polyurethane (TPU). Before the appearance of the special-shaped screen led by the iPhone X, there was enough distance between the screen and the upper and lower edges of the phone, and the ordinary TPU protective case could protect the phone screen. However, with the increasing proportion of mobile phone screens, the risk of broken screens due to falling mobile phones is getting higher and higher.

With the increasing demand for lighter and thinner smartphones in the market, and the advancement of mobile phone manufacturing processes, the integration of mobile phone screens is also getting higher and higher. Now to replace the mobile phone screen, special equipment is required, so the cost is very high. The cost can usually reach 1/3 of the price of a mobile phone, causing users to be forced to buy a new mobile phone, resulting in a great waste of resources and the environment and more pollution. And these wastes and pollution could have been avoided. What users need is a mobile phone case that is light and thin and can fully protect the screen.

The US invention patent US 8,909,309 discloses a mobile device protective cover with a buffering device, but it is used to protect the corners of the adjacent sides of the mobile device, and cannot effectively protect the front screen.

The US invention patent US 9,247,795 implements an electronic device protective cover with an energy-absorbing structure, but its energy-absorbing structure is mainly used to protect the back panel of a mobile phone, and it cannot effectively avoid broken screens.

The US invention patent US 9,553,629 describes a set of protective clips that can be firmly installed on the edges and corners of portable electronic devices without the help of tools or glue. However, for high-screen-to-body mobile phones, tablets, and laptops with special-shaped screens, fixed protection The space occupied by the folder is too large, which will affect the user's use.

Summary of the invention

The mobile phone protective film can reduce the risk of broken screen to a certain extent. However, due to the problem of manufacturing accuracy and the need to avoid the protective film from being rolled up and falling off, the common protective film is usually smaller than the mobile phone screen and cannot fully protect the screen. , But more played a role of scratch resistance. We can also use a mobile phone case that fully protects the screen to circumvent the manufacturing accuracy problem.

The embodiment of the present invention provides a portable device protective cover:

·The protective cover includes a bottom surface and a side surface, and the corners of adjacent sides have an extended structure

·The extension structure can be perpendicular to the screen of the device to form a user-oriented extension and energy-absorbing structure

·The extension structure can also be placed on the corners of the adjacent sides of the device to form an energy-absorbing structure that fits the screen of the device

The attached picture shows the mobile phone protective cover. However, the embodiments of the present invention are not limited to the application of mobile phone protective sleeves. For example, other electronic devices that include display screens, such as tablets and laptops, can also use the protective case described below.

The most common display screen for portable devices is liquid crystal (LCD), which can be divided into a protective layer, a touch layer, and a display layer. The protective layer is usually tempered glass (such as gorilla, sapphire glass, etc.). After the emergence of the special-shaped screen led by iPhone X, the risk of mobile phone being broken due to falling or other external forces is increasing. In most cases, only the tempered glass of the protective layer of the LCD screen is damaged, and it is usually caused by impacts on the four corners of the screen. Then, as long as the four corners of the display are protected, the risk of broken screen can be greatly reduced.

The US invention patents US 8,909,309 and US 9,247,795 respectively protect the corners of the adjacent sides of the device and the back panel of the mobile phone. The back panel is the most resistant part of the portable device. The corners of the adjacent sides are fully protected by the protective cover. In addition, the phone shell can also absorb impact energy.

The common mobile phone cases in the market can be divided into bottom and side. In order to pursue a rounded feel in modern smartphones, the bottom and sides are usually curved. Then, there are two ways to protect the four corners of the display: avoid direct impact on the four corners of the display, or buffer the damage caused by impact.

The former can extend outward from the side of the protective cover adjacent to the four corners of the display screen ("inner" is the space for the protective cover to accommodate portable devices, and "outward" extends toward the direction of the user), so that when the phone falls or is impacted by other external forces At this time, the four corners of the display screen will not be impacted, unless the extension part is greatly deformed, so that the four corners of the display screen are also impacted by the ground/impacting object. The impact force can be fixed by the buckle of the portable device through the protective cover and transferred to the more slamming device casing, or it can be buffered by the deformation of the elastic material.

The latter can extend horizontally (parallel to the display screen of the portable device) where the sides of the protective cover are adjacent to the four corners of the display. The extended part can be made of elastic material, so that when the phone is dropped or is impacted by other external forces, the four corners of the display are not Will be directly impacted, and the elasticity of the extension can be cushioned to increase the impact time. According to the law of conservation of momentum, for the same momentum, the longer the impact time, the smaller the force generated by the impact and the smaller the damage to the four corners of the display.

Furthermore, these extensions can include one or more layers of airbags to increase their cushioning capacity. The airbags can even be designed to have a fragile structure at a certain location. After an impact, gas can leak through this structure, further increasing the redundancy of absorbing impact energy. degree.

In addition, for portable devices with double-sided screens (for example, there are screens on the back of mobile phones), the above methods can also be applied to protect the corners of the screen. In addition, these methods can also be used to protect the glass backplanes of portable devices.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention. Various changes and modifications according to the claims and specification of the present disclosure are still within the scope of the claimed invention.
