Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

Please refer to fig. 1, 2, 3 and 4 in combination, the present invention provides a front and rear protective film cover for a mobile device, which includes a front film cover 1 for protecting the front of the mobile device and a rear film cover 2 for protecting the rear of the mobile device, wherein the edges of the front film cover 1 and the rear film cover 2 can be folded with each other, and a cavity formed between the front film cover 1 and the rear film cover 2 completely covers the mobile device.

Wherein, preceding membrane lid 1 includes half preceding lateral part 11 and diaphragm 12 before, half preceding lateral part 11 sets up around diaphragm 12, and half preceding lateral part 11 bonds with diaphragm 12 mutually, the internal surface coating of diaphragm 12 has first glue film 13, back membrane lid 2 includes half back lateral part 21 and bottom 22, half back lateral part 21 sets up around bottom 22, and half back lateral part 21 and bottom 22 integrated into one piece, the internal surface coating of bottom 22 has second glue film 23, half preceding lateral part 11 and half back lateral part 21 are involutive each other in order to totally wrap up the side of mobile device.

It should be noted that the adhesion between the first adhesive layer 13 and the screen film of the mobile device is smaller than the adhesion between the second adhesive layer 23 and the back surface of the mobile device. The front film cover is used for protecting the screen of the mobile equipment, so that good connectivity between the front film cover and the mobile equipment is ensured, and the touch sensitivity of the screen of the mobile equipment cannot be influenced, therefore, the thickness of the first adhesive layer coated on the film is as thin as possible, the influence on the touch of a user on the screen through the film is avoided, and the adhesion of the film cannot be influenced by a small amount of the first adhesive layer, because a certain electrostatic adsorption force exists between the film and the screen, the adhesion force between the film and the screen is strengthened; in order to adhere the rear film cover to the back of the mobile device, the thickness of the second adhesive layer is increased to ensure that the rear film cover does not easily fall off the back of the mobile device.

In addition, the surfaces of the first adhesive layer 13 and the second adhesive layer 23 are covered with a layer of isolation film 3. Before assembling preceding membrane lid and back membrane lid to the mobile device that needs to treat the protection on, guarantee first glue film, second glue film can not receive the pollution of external dust through the barrier film.

Present mobile device is various, and the different mobile device backs all are provided with the sign that can represent self product characteristic, and the utility model provides a front and back protective film lid can live the whole complete parcel of mobile device, consequently in order to be convenient for the user to look over the product sign of being wrapped up the mobile device, so an sign mouth 24 has been seted up at the intermediate position of bottom 22, installs transparent film 25 on the sign mouth 24. The position that the sign mouth was seted up is adjusted according to the sign on the mobile device back, and user or other people can see the trade mark of treating the protection mobile device back through the transparent film on the sign.

Furthermore, the front half side part 11 of the front film cover 1 and the whole rear film cover 2 are made of plastic vacuum forming. Technical personnel can consider and have the ability that corresponding notches are correspondingly arranged on the front half side edge part and the rear half side edge part according to the positions of the keys, the receivers, the loudspeakers and the charging ports of the side edge of the mobile equipment, so that when the equipment to be protected is placed in a cavity formed between the front film cover and the rear film cover, the assembly cannot be influenced by the positions of the keys, the receivers, the loudspeakers and the charging ports of the mobile equipment, and the front half side edge part and the rear half side edge part are processed into the shape of the side edge of the mobile equipment to be protected by adopting a plastic vacuum forming manufacturing mode for facilitating processing.

Further, the utility model discloses what diaphragm 12 chooseed for use on the preceding membrane lid 1 is comparatively general a transparent toughened glass diaphragm on the market, and it can effectively protect mobile device's screen, prevents that the screen from breaking into pieces or scratch.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
