本发明涉及便携式设备平面保护套,具体涉及一种通过加强对设备屏幕角落的保护,减少因设备跌落或其它外力碎屏的概率的保护套。The invention relates to a flat protective cover for a portable device, and in particular to a protective cover that reduces 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.
最常见和常用的便携式设备保护套,当然是手机保护套,通常由热塑性聚氨酯(Thermoplastic Polyurethane,TPU)制成。在iPhone X引领的异形屏出现以前,屏幕到手机上下边缘有足够的距离,普通TPU保护套即能保护手机屏幕。然而,随着手机屏占比越来越高,因手机跌落而碎屏的风险越来越高。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.
随着市场竞争对手机轻薄的要求越来越高,和手机制造工艺的进步,手机屏幕的集成度也越来越高。现在要更换手机屏幕,需要专门设备,因此成本很高。其代价通常能达到手机价格的1/3,导致用户被迫购买新手机,造成了对资源和环境的极大浪费和更多污染。而这些浪费和污染本可以避免,用户需要的是轻薄且能充分保护屏幕的手机套。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.
美国发明专利US 8,909,309公开了一种具有缓冲装置的移动设备保护套,但其用于保护移动设备相邻侧边的角,并不能有效保护正面屏幕。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.
美国发明专利US 9,247,795实现了一种具有吸能结构的电子设备保护套,但其吸能结构主要用于保护手机背板,并不能有效避免碎屏。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.
美国发明专利US 9,553,629描述了一套可以不借助工具或粘胶就能自己牢固的安装在便携式电子设备棱角的保护夹,然而,对于高屏占比的异形屏手机、平板、笔记本电脑,固定保护夹需要占用的空间过大了,会影响用户的使用。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.
发明概述Summary of the invention
手机保护膜能在一定的程度上降低碎屏的风险,然而,因为制造精度的问题,和避免保护膜卷起导致脱落的需要,常见的保护膜通常比手机屏幕小一些,并不能充分保护屏幕,而是更多的发挥了防刮的作用。我们也可以利用一个充分保护屏幕的手机套,来绕开制造精度难题。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.

便携式设备最常见的显示屏是液晶(LCD),可分为保护层、触控层和显示层。保护层通常为钢化玻璃(例如大猩猩、蓝宝石玻璃等)。在iPhone X引领的异形屏出现后,手机因跌落或其它外力碎屏的风险越来越大。大部分情况下,液晶屏只是保护层的钢化玻璃损坏了,而且通常都是显示屏四个角落受到撞击导致。那么,只要保护好显示屏的四角,就能极大程度降低碎屏的风险。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.
美国发明专利US 8,909,309和US 9,247,795分别保护了设备的相邻侧边的角和手机背板,而背板是便携式设备最耐摔的部分,相邻侧边的角,除了会得到保护套充分保护外,手机外壳也可以吸收撞击能量。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.
市场上常见的手机套,可以分为底面和侧面。现代智能手机为了追求圆润的手感,底面和侧面通常为曲面。那么,有两种方法保护显示屏的四角:避免显示屏的四角直接冲击,或者缓冲撞击造成的破坏。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.
前者可以在保护套侧面邻接显示屏四角之处向外延伸(“内”为保护套容纳便携式设备的空间,向“外”延伸即面向使用者的方向),这样当手机跌落或受到其它外力冲击时,显示屏的四角就不会受到冲击,除非所属延伸部分产生极大形变,以至于显示屏的四角也受到地面/撞击物体的冲击。冲击力可以通过保护套固定便携式设备的卡扣,转移到更加扛摔的设备外壳上,也可以通过弹性材料形变进行缓冲。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.
后者可以在保护套侧面邻接显示屏四角之处水平延伸(平行于便携式设备显示屏),延伸的部分可由弹性材料制成,这样当手机跌落或受到其它外力冲击时,显示屏的四角就不会受到直接冲击,延伸部分的弹性可以缓冲以增加撞击时间。根据动量守恒定律,对于相同动量,撞击时间越长,撞击产生的力量就越小,对显示屏四角的破坏就越小。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.
进一步而言,这些延伸可以包含一层或多层气囊,以增加其缓冲能力气囊甚至可以设计成某个位置的结构脆弱,受到撞击后可通过此结构泄露气体,进一步增加吸收撞击能量的冗余度。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.
此外,对于双面屏便携式设备(例如手机背面也有屏幕),也可以应用以上方法保护屏幕角落。此外,这些方法也可以用来保护便携式设备的玻璃背板。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.
以上描述仅是本发明的实施例,并不意在限制本发明的范围。根据本公开的权利要求书和说明书的各种变化和修改仍在所要求保护的发明的范围内。此外,每个实施例和权利要求书未必包含了所公开的所有优点或特性。此外,摘要和标题仅用于便于搜索专利文献,并且不旨在以任何方式限制所要求保护的发明的范围。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. In addition, each embodiment and claims may not include all the advantages or characteristics disclosed.
