The present application provides a protective film for an electronic terminal, which is configured to be attached to an electronic terminal mounted with a camera and protect a screen of the electronic terminal.

In one embodiment of the present application, as shown in <FIG> and <FIG>, the protective film for an electronic terminal includes a protective film body and a shielding member <NUM>. The protective film body is provided with an avoidance hole <NUM> and an accommodation cavity, and the avoidance hole <NUM> is in communication with the accommodation cavity, and configured to avoid the camera when the protective film body is attached to the electronic terminal, so that when a user needs to use the camera, the camera is not shielded by the protective film body, ensuring that the camera can be used normally. The shielding member <NUM> is movably disposed in the accommodation cavity, and configured to shield or not shield the camera. When the shielding member <NUM> is located at a position where the avoidance hole <NUM> is located, the camera is shielded by the shielding member <NUM>, thereby protecting the privacy of the user. When the shielding member <NUM> is moved to a position deviating from the avoidance hole <NUM> in the accommodating cavity, the camera is not shielded by the shielding member <NUM>, thereby enabling the camera to be used normally.

By adopting the protective film body, the technical scheme of the present application can play a role of protecting the screen, prevent the screen from being scratched, at the same time, it reduces the probability of the screen being smashed. By adopting the avoidance hole <NUM> and the accommodating cavity defined on the protective film body, the avoidance hole <NUM> avoids the camera, the shielding member <NUM> is movably disposed in the accommodating cavity, and can be moved to different positions of shielding the camera or not shielding the camera in the accommodating cavity. When the camera needs to be used, the shielding member <NUM> can be moved to a position where the camera is not shielded, thus to normally use the camera, when the camera is not needed, the shielding member <NUM> can be moved to the position of shielding the camera, thereby protecting the privacy of the user, that is, the technical scheme of the present application can protect the privacy of the user while protecting the screen.

In the embodiment of the present invention, the protective film body includes a first bonding layer <NUM> and a second bonding layer <NUM>. The first bonding layer <NUM> is attached to the electronic terminal to protect the screen, and the avoidance hole <NUM> penetrates through the first bonding layer <NUM> and the second bonding layer <NUM>. An edge of the second bonding layer <NUM> is attached to the first bonding layer <NUM>, and a position corresponding to a middle part of the second bonding layer <NUM> forms the accommodating cavity to cover the shielding member <NUM>. When the protective film is attached to the electronic terminal to protect the screen, the shielding member <NUM> can play a role in protecting privacy, and no limiting and fixing structure for limiting and fixing the shielding member <NUM> is needed.

In some embodiments, the second bonding layer <NUM> has a shape matching a shape of the avoidance hole <NUM>, and the edge of the second bonding layer <NUM> is bonded with a periphery of the avoidance hole <NUM>. It can be understood that a size of the second bonding layer <NUM> may be the same as a size of the first bonding layer <NUM>, or may be adaptively reduced according to a size of the avoidance hole <NUM> to save raw materials.

In one embodiment, the edge of the second bonding layer <NUM> and the first bonding layer <NUM> are hot-pressed and bonded. By hot-pressing and bonding the edge of the second bonding layer <NUM> and the first bonding layer <NUM>, the forming process of the accommodating cavity is simple and convenient, and it brings less damage to the protective film body, thereby prolonging the service life of the protective film body. Further, after the edge of the second bonding layer <NUM> and the first bonding layer <NUM> are hot-pressed and bonded to each other, the second bonding layer <NUM> and the first bonding layer <NUM> form a bag-like structure which covers the shielding member <NUM>, so that the shielding member <NUM> is not easy to fall off during the use of the electronic terminal protective film, and better protects the privacy of the user.

In one embodiment, the edge of the second bonding layer <NUM> and the first bonding layer <NUM> are hot-pressed and bonded, the middle part of the second bonding layer <NUM> is protruded upwardly, and a height of the upward protrusion of the second bonding layer <NUM> matches a thickness of the shielding member <NUM>, so as to form the accommodating cavity in the middle part of the protective film body. As that the second bonding layer <NUM> is protruded upward to form the accommodating cavity matched with the thickness of the shielding member <NUM>, when the shielding member <NUM> is positioned in the accommodating cavity, the extrusion and friction between the shielding member <NUM> and inner walls of the accommodating cavity are small, thereby making the shielding member <NUM> move more smoothly in the accommodating cavity.

In one embodiment, the second bonding layer <NUM> is provided with a strip-shaped avoidance groove <NUM>, the avoidance groove <NUM> is in communication with the avoidance hole <NUM>, the shielding member <NUM> is at least partially exposed in the avoidance groove <NUM>, and the shielding member <NUM> is arranged so that the user slides the shielding member <NUM> along a length extension direction of the avoidance groove <NUM>. By providing the avoidance groove <NUM>, the user can directly contact the shielding member <NUM>, so that the shielding member <NUM> can be slid more smoothly, and it is more convenient for the user to move the shielding member <NUM>.

In one embodiment, the shielding member <NUM> is provided with a protrusion <NUM> extended out of the avoidance groove <NUM> and configured for the user to slide the shielding member <NUM> along the length extension direction of the avoidance groove <NUM>. The arrangement of the protrusion <NUM> provides a more convenient focus for the user to move the shielding member <NUM>, so that it is more convenient for the user to move the shielding member <NUM>. The arrangement of the avoidance groove <NUM> enables the protrusion to slide along the length extension direction of the avoidance groove <NUM>, so as to prevent the user from sliding the shielding member <NUM> in a wrong direction and causing impact on the bonding place between the second bonding layer <NUM> and the first bonding layer <NUM>, and avoid damage to the protective film body during the sliding process of the shielding member <NUM>.

Referring to <FIG>, in an embodiment, the shielding member <NUM> is completely located in the avoidance groove <NUM>, and a surface of the shielding member <NUM> is provided with anti-skid lines <NUM>, thereby increasing the friction when the user moves the shielding member <NUM>, and making the movement smoother.

In one embodiment, the protrusion <NUM> is shaped as a truncated cone, and an upper surface of the protrusion <NUM> is provided with the anti-skid lines <NUM>, thereby increasing the friction when the user moves the shielding member <NUM>, and making the movement smoother. In addition, the truncated cone-shaped arrangement enables the electronic terminal to be placed more stably.

Referring to <FIG>, in one embodiment, the protrusion <NUM> is shaped as a hemispherical or is another type arc-shaped protrusion, so that the surface of the protrusion <NUM> is smooth, reducing the wear of the notch of the avoidance groove <NUM> by the protrusion <NUM> during the sliding process of the shielding member <NUM> and prolonging the service life of the protective film body.

In one embodiment, the shielding member <NUM> is an opaque circular piece. The camera is shielded by the opaque circular piece, thus protecting the privacy of the user. Since the shielding member <NUM> is a circular piece, when the user slides the shielding member <NUM>, a contact area between a side wall of the shielding member <NUM> in a thickness direction and the cavity wall of the accommodating cavity is small, and thus the resistance in the sliding process is small. The shielding member <NUM> can be quickly slid off when the camera needs to be used, and the convenience of use is improved. The shielding member <NUM> can be quickly slide to shield the camera when the camera is not needed, the convenience of operation is improved, and the probability that the user chooses to give up the operation of sliding the shielding member <NUM> to shield the camera because the operation is not convenient enough is reduced, thereby reducing the probability of the leakage of the user's privacy. In an embodiment, an surface of the shielding member <NUM> is presented as a black matte surface, which plays a shielding role and does not generate dazzling reflection.

Referring to <FIG>, in an embodiment, both the first bonding layer <NUM> and the second bonding layer <NUM> have inner sides facing inside of the accommodating cavity, and the inner sides of the first bonding layer <NUM> or the inner sides of the second bonding layer <NUM> are defined with a sinking groove <NUM> corresponding to the periphery of the avoidance hole <NUM>. A shape of the sinking groove <NUM> matches a shape of the shielding member <NUM>, and is configured to accommodate the shielding member <NUM> when the shielding member <NUM> shields the camera, so that when the camera does not need to be used and the camera is shielded by the shielding member <NUM>, the shielding member <NUM> is received in the sinking groove <NUM>. Understandably, the time of the state that the shielding member <NUM> does not shield the camera is only the time when the user uses the camera, which accounts for a small portion of the user's use of the electronic terminal. The time of the state that the shielding member <NUM> shields the camera accounts for a big portion of the user's use of the electronic terminal. In this embodiment, the sinking groove <NUM> is provided at the periphery of the avoidance hole <NUM>, so that when the shielding member <NUM> shields the camera, the shielding member <NUM> is accommodated in the sinking groove <NUM>, so that it avoids the occurrence of the shielding member <NUM> being supported by the protective film for a long time during most of the time the user using the electronic terminal and causing damage to the protective film body.

In one embodiment, the notch of the sinking groove <NUM> is rounded to make the notch of the sinking groove <NUM> smooth on one hand, thereby preventing the notch of the sinking groove <NUM> from abrading the second bonding layer <NUM> after the shielding member <NUM> leaves the sinking groove <NUM>, and on the other hand to enable the user to slide the shielding member <NUM> out of the sinking groove <NUM> more smoothly, which is convenient for use.

In the embodiment of the present invention, the protective film body is transparent. The first bonding layer <NUM> has an inner side toward the inside of the accommodating cavity, an opaque warning part (not shown) is provided on the inner side of the first bonding layer <NUM> corresponding to the periphery of the avoidance hole <NUM>. A shape of the warning part is matched with the shape of the shielding member <NUM>, and is configured to warn the user when the shielding member <NUM> does not shield the camera, so as to remind the user that the camera is not shielded, and attention should be paid to shielding the camera or exposing privacy in front of the camera, thereby reducing the probability of privacy leakage.

In one embodiment, the warning part is a red opaque layer, and the red opaque layer can be arranged on the periphery of the avoidance hole <NUM> by means of hot pressing, adhesion, coating, or the like, so that the process is simple, the warning part is more eye-catching, and the user is better reminded that the camera is not shielded, thereby reducing the probability of privacy leakage.

In other embodiments, the warning part can be arranged as an opaque layer of another color, such as a fluorescent color, to achieve a striking effect, so that users can more easily find that the camera is not shielded, thereby reducing the probability of privacy leakage.

In the above embodiment, the first bonding layer <NUM> has an outer side facing the outside of the accommodating cavity, and the outer side of the first bonding layer <NUM> is provided with an adhesive layer (not shown in the figures), so that the protection film of electronic terminal is easily attached to the electronic terminal, and not easy to fall off, thereby better protecting the privacy of the user.

In some embodiments, the adhesive layer is <NUM> double-sided adhesive tape, which has good adhesion effect and is convenient and quick to operate, such as non-woven substrate double-sided adhesive tape, non-substrate double-sided adhesive tape, PET substrate double-sided adhesive tape, foam substrate double-sided adhesive tape, hot melt adhesive film, high temperature resistant adhesive tape, or the like.

In one embodiment, the adhesive layer is provided with a release paper, and the release paper completely covers the first bonding layer <NUM>, and is provided with a protruding part beyond the first bonding layer <NUM>, thereby facilitating the user to tear off the release paper from the adhesive layer when attaching the protection film of electronic terminal to the terminal, and improving the convenience of operation.

In the above-described embodiment, each of thicknesses of the second bonding layer <NUM>, the first bonding layer <NUM>, and the shielding member <NUM> is ranged from <NUM> to <NUM>. It can be understood that the greater the thickness of the protective film for an electronic terminal, the greater the negative impact on the user's comfort. In the above embodiment, the thicknesses of the second bonding layer <NUM>, the first bonding layer <NUM>, and the shielding member <NUM> are set to be less than or equal to <NUM>, thereby ensuring the user's comfort. The smaller the thickness of the protective film for an electronic terminal, the higher the processing difficulty and cost. In the above embodiment, the thicknesses of the second bonding layer <NUM>, the first bonding layer <NUM>, and the shielding member <NUM> are set to be greater than or equal to <NUM>, thereby reducing the production and processing difficulty and cost of the protective film for an electronic terminal on the premise of ensuring the user's comfort.

Specifically, each of the thicknesses of the second bonding layer <NUM>, the first bonding layer <NUM>, and the shielding member <NUM> may be set to <NUM>, <NUM>, <NUM> or <NUM>. Alternatively, the thicknesses of the second bonding layer <NUM>, the first bonding layer <NUM>, and the shielding member <NUM> may be set to be different but all are in the range of <NUM> to <NUM>, so that the requirement of processing accuracy is reduced and the difficulty of production and processing is further reduced on the premise of ensuring the user's comfort.
