Before the embodiments are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The application is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of the terms "comprising," "including," "having," and the like are intended to encompass the items listed thereafter and equivalents thereof as well as additional items. In particular, when "a certain element" is described, the present application is not limited to the number of the element as one, but may include a plurality of the elements.

As shown in fig. 1 and 3, the present application provides an air bag protection film which can be used on a screen of an electronic device such as a mobile phone, a pad, etc., wherein the air bag protection film includes a first protection layer 10 and a second protection layer 20, and an edge of the first protection layer 10 is hermetically connected with an edge of the second protection layer 20 to form a sealed air bag structure 30 between the first protection layer 10 and the second protection layer 20. As can be seen in fig. 3, other portions of the first protective layer 10 and the second protective layer 20 are spaced apart from each other except for the edge sealing connection to form a cavity, i.e., the balloon structure 30. When the first protection layer 10 is stressed, the first protection layer 10 deforms towards the second protection layer 20, and due to the existence of the air bag structure 30, a space is provided for the deformation of the first protection layer 10, and the impact force received by the first protection layer 10 is reduced after the deformation, so that a buffer effect is achieved. The material of the first protective layer 10 and the second protective layer 20 may be glass or plastic transparent material, and the plastic transparent material may be PET, PC, etc.

In a more preferred embodiment, the cushioning layer 50 may also be filled within the balloon structure 30. The protective film shown in fig. 7 is a protective film adapted to the display screen of the head-mounted display device, and the protective film fills the buffer layer 50 in the air bag structure 30, so that the impact force applied to the first protective layer 10 can be further reduced by the deformation of the buffer layer 50. Further, an array structure may be disposed on the buffer layer 50. The array structure can have various forms, can be holes arranged in an array manner, is similar to a sponge structure, and has better buffering effect on the buffer layer 50; the buffer structure can be in an array arrangement, such as columnar bulges, conical bulges and the like, and spaces are formed among the bulges so as to improve the buffer effect; may be a grid-like structure with spaces formed between the grids. In other embodiments, the array structure may be in other forms, as long as the buffer effect can be achieved, and the present application is not limited to the examples.

In another embodiment, cushioning medium may also be filled within bladder structure 30 to enhance cushioning capacity. The buffer medium may be a gas, a liquid or a solid. Only one of them may be filled or a plurality of them may be filled at the time of filling. Furthermore, when filling the buffer medium, the buffer medium which can conduct heat or dissipate heat, such as heat dissipation liquid, can be considered to be filled, and when the anti-falling effect is achieved, the anti-falling buffer medium can also play a role in heat dissipation, so that a user can have better operation experience when using electronic equipment such as a mobile phone, a pad and the like.

Referring to fig. 3-6, there are various implementations of sealing and connecting the edges of the first protective layer 10 and the second protective layer 20.

In fig. 3, the first protective layer 10 includes a main body portion and a connection portion 11 located at a circle of an edge of the main body portion, and the connection portion 11 protrudes from the edge of the main body portion toward the second protective layer 20. The connection portion 11 is in contact with and sealed against the edge of the second protective layer 20, while the presence of the connection portion 11 forms an air-bag structure 30 between the body portion and the second protective layer.

In fig. 4, unlike fig. 3, the first protective layer 10 includes a first body portion and a first connection portion 12 located at a circle of an edge of the first body portion, the first connection portion 12 protruding from the edge of the first body portion toward the second protective layer 20. Similarly, the second protective layer 20 includes a second main body portion and a second connection portion 21 located at a circle of an edge of the second main body portion, and the second connection portion 21 protrudes from the edge of the second main body portion toward the first protective layer 10. The first connecting portion 12 and the second connecting portion 21 are in contact and then are hermetically connected.

In fig. 5, in order to make the sealing connection more firm, a protrusion 121 is provided at a layer of the first connection portion 12 facing the second protection layer 20, a groove 211 is provided at a side of the second connection portion 21 facing the first protection layer 10, and the connection of the first protection layer 10 and the second protection layer 20 is made more firm by the concave-convex fit of the protrusion 121 and the groove 211. During production, the connecting is firstly carried out through concave-convex matching, and then final sealing and fixing are carried out through modes of gluing, welding and the like.

In fig. 6, the sealing connection of the first protective layer 10 and the second protective layer 20 is achieved by introducing a ring-shaped connection 40. The annular connecting member 40 is disposed between the first protective layer 10 and the second protective layer 20 and at the edges of the first protective layer 10 and the second protective layer 20, and then the first protective layer 10 and the second protective layer 20 are respectively connected with the connecting member 40 in a sealing manner, and the connecting member 40 separates the first protective layer 10 and the second protective layer 20 and forms the air bag structure 30.

Referring to fig. 7, when the air bag protecting film is applied to the mobile phone screen, in order to prevent shielding the earphone, a call of the mobile phone is cited, and an avoidance hole is required to be provided. Through set up first hole 13 of dodging on first protective layer 10, set up the second on the second protective layer and dodge hole 22, and the first hole 13 of dodging and the position that the hole 22 was dodged to the second correspond to the sound that cell-phone earphone produced can pass first hole 13 and the hole 22 of dodging and pass the ear of user, has avoided the shielding of gasbag protection film to the cell-phone earphone. Further, since the arrangement of the first avoidance hole 13 and the second avoidance hole 22 may damage the tightness of the air bag structure 30, the edges of the first avoidance hole 13 and the second avoidance hole 22 are in sealing connection, so that the tightness of the air bag structure 30 can be maintained, and the arrangement of the avoidance hole cannot damage the air bag structure 30.

Further, in order to make the air bag protection film easier to attach to the screen of the electronic device, an adhesive layer 60 is further disposed on a side of the first protection layer 10 away from the second protection layer 20, where the adhesive layer 60 is, for example, an AB adhesive, a double sided adhesive, or the like, and is used for stably attaching the air bag protection film to the surface of the electronic device. The adhesive layer 60 may also be disposed on a side of the second protective layer 20 remote from the first protective layer 10.

Further, in order to ensure the adhesiveness of the adhesive layer 60 during transportation, a release layer 70 is further provided on the surface of the adhesive layer 60, and when the user sticks to the film, the release layer 70 is torn off, and then the air bag protection film is stuck to the screen of the electronic device through the adhesive layer 60.

The concepts described herein may be embodied in other forms without departing from the spirit or characteristics thereof. The particular embodiments disclosed are illustrative and not restrictive.
