Description

Toughened film with high protection effect Technical Field The utility model relates to the technical field of toughened films, in particular to a toughened film with a high protection effect. Background In the current digital age, portable electronic devices such as smart phones, tablet computers, smart watches and the like are deeply integrated into the work, life and entertainment of people. The screen of these devices acts as a core carrier for information presentation and operational interactions, the integrity and lifetime of which directly affect the user's use experience. However, during the daily carrying and use process, the electronic device is inevitably subject to various unexpected conditions, such as sliding from the pocket or the table top, friction generated when the electronic device is placed in the bag together with hard objects such as keys and coins, or collision with other objects when the electronic device is used. The conditions are very easy to cause scratches, cracks and even breakage of the screen, so that normal use of the equipment can be influenced, and high maintenance cost can be paid, so that a plurality of inconveniences and losses are brought to users. Therefore, equipping electronic devices with effective screen saver products to reduce the risk of screen damage has become a popular need for a wide range of users. Among the numerous screen saver products, tempered glass films have taken up the mainstream market by virtue of their remarkable advantages. The toughened glass film is characterized in that the surface of the toughened glass film is subjected to special chemical or physical treatment to form compressive stress on the surface of the ordinary glass, so that the toughened glass film has higher surface hardness, and the Mohs hardness can reach 6-7 levels, so that the toughened glass film can effectively resist slight scraping in daily use, and the possibility of scratching a screen is reduced. Meanwhile, the toughened glass film has good light transmittance, the general light transmittance can reach more than 90%, the display effect of the screen can be prevented from being influenced to the greatest extent, and a user can clearly watch the content of the screen. In addition, the toughened glass film is relatively simple and convenient to install, has high laminating degree, can not obviously influence the touch sensitivity of equipment, is widely favored by consumers, and becomes a preferred scheme for protecting the screen of the electronic equipment. However, although the tempered glass film has the above-mentioned advantages, there are still considerable drawbacks in terms of its protective properties in practical applications. In structural design, the edge part of the traditional toughened glass film is mostly in a bare state, and no extra protective measures are provided. This design makes the protective ability of the toughened film significantly compromised in the face of specific situations. For example, when an electronic device falls carelessly, corners often contact the ground first, and the edges of the tempered film directly bear huge impact force, or when the device is impacted from the direction of the corners, the stress borne by the edges is more concentrated. In these cases, the edges of the tempered film are easily chipped. Once the edge of the toughened film is cracked, the protective effect on the corresponding area of the screen of the electronic equipment can be lost, so that the screen is directly exposed in an environment which is possibly damaged, and the sharp fragments generated after the cracking can scratch the fingers of a user, so that certain potential safety hazards exist. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a technical scheme capable of solving the problems. A high protective effect toughened film comprising: the toughened film main body is used for covering the screen of the electronic equipment; The protective edge structure is arranged at the edge part of the toughened film main body and comprises a buffer layer and a hard layer, the buffer layer wraps the side edge of the toughened film main body, the hard layer is arranged at the outer side of the buffer layer, and the outer surface of the hard layer is flush with the outer surface of the toughened film main body; The functional coating covers the surface of the toughened film main body and comprises one or more of a blue light resistant coating, an oleophobic coating and an anti-fingerprint coating. As a further scheme of the utility model, the buffer layer is an elastic rubber layer or a silica gel layer. As a further scheme of the utility model, the hard layer is made of a metal material or high-strength engineering plastic. According to the utility model, an electrostatic adsorption layer is arranged on one side of the toughened film main body, which is close to the screen of the electronic equipment,
