Title: Stand-alone type mobile phone sandwich sheet for securing accessories

Description:
BACKGROUND OF THE INVENTION 
     Technical Field 
     The present invention belongs to the technical field of accessory products for mobile phones, and in particular to a stand-alone type mobile phone sandwich sheet for securing accessories. 
     2. Description of Related Art 
     A mobile phone is not only a tool capable of answering a call, but also a tool integrating the functions of office work, entertainment, games and the like. When in various environments while traveling, at home, in bed and the like, people tend to kill longer and longer amounts of time with their mobile phone. A mobile phone pendant, or in other words, an accessory, is diverse in type and mainly plays the role of decorating the mobile phone, while some pendants have other auxiliary functions. 
     However, in consideration of cost, stability, applicable range, compatibility and other factors, the design for hanging the accessory (for example, a hole, a hook, a perforation and other designs for hanging the accessory) has been canceled in most of the mobile phones in the market at present. A user may not directly bind other accessories or fixing devices with the mobile phone, and thus, a certain inconvenience is brought to the life and work of the user. 
     A mobile phone shell or mobile cover also belongs to accessory products of mobile phones (in the present patent, the mobile phone shell and the mobile cover have the same meaning) and mainly plays a role of protecting the mobile phone. Some of the mobile phone covers have a design for hanging an accessory, such as a hook, a perforation and others for the accessory. For a mobile phone cover already having a hanging accessory in design, the relatively complex firmware added for enhancing the reliability destroys the overall simplicity. 
     For users who have bought products such as a mobile phone cover having no hook, perforation and other designs, it is difficult to bind other accessories or fixing devices with the mobile phone in the event of not separately purchasing a new product. 
     BRIEF SUMMARY OF THE INVENTION 
     The technical problem to be solved by the present invention is as follows: a hook or a hole for securing accessories must be bound with a mobile phone shell or a mobile phone cover. If an existing mobile phone shell or a mobile phone cover of a user has no such design, he/she has to repeat the purchase, thereby increasing the cost for the user, what&#39;s worse, the user must abandon the mobile phone shell or mobile phone cover used currently, and meanwhile, the range for the user to select the mobile phone shell or cover products is greatly reduced; moreover, the design of the hook or hole as being wholly integrated with the mobile phone shell or cover cannot be split; and furthermore, the existing product design of the mobile phone shell or cover having the accessory hook or hole is complicate and is inconsistent with the trend of simple style of electronic products. 
     To solve the problem as described above, the present invention employs a technical solution as follows: 
     a stand-alone type mobile phone sandwich sheet for securing accessories includes at least one sandwich piece, wherein the sandwich piece includes a sandwich piece body and an extension portion; the extension portion is formed by extending one end of the sandwich piece body and includes an accessory fixing mechanism capable of being provided with an external-source accessory; the sandwich piece body is accommodated in a gap formed between a mobile phone and a mobile phone cover; and the extension portion is located outside the gap formed between the mobile phone and the mobile phone cover. 
     Further, the shape of the sandwich piece body fits the gap formed between the mobile phone and the mobile phone cover. 
     As a preferred implement, the stand-alone type mobile phone sandwich sheet for securing accessories includes two sandwich pieces, wherein the sandwich piece body of one sandwich piece is overlapped with the sandwich piece body of the other sandwich piece; the extension portion of one sandwich piece is overlapped with the extension portion of the other sandwich piece; and a sandwich layer is formed between the two sandwich pieces. 
     As a preferred implement, the sandwich layer is internally provided with an enhancing member. 
     As a preferred implement, the sandwich piece is made from a textile cloth, plastic, paper or metal material. 
     As a preferred implement, the accessory fixing mechanism is a hole formed in the extension portion, or a hook or binding tie configured on the extension portion. 
     As a preferred implement, the enhancing member is made from a metal, wood or plastic material. 
     As a preferred implement, the enhancing member is a sticker or an adhesive tape. 
     As a preferred implement, the sandwich piece is fixed at a side where the mobile cover and the mobile phone are laminated. 
     As a preferred implement, the sandwich piece is stuck to the mobile phone cover. 
     The stand-alone type mobile phone sandwich sheet of the present invention at least has the following advantageous effects or advantages: 
     the stand-alone type mobile phone sandwich sheet creatively makes full use of a large-area interspace space between the mobile phone cover and the mobile phone by disposing at least one sandwich piece in the interspace; the sandwich piece includes the sandwich piece body and the extension portion; the sandwich piece body is accommodated in the gap formed between the mobile phone and the mobile phone cover; and the extension portion is located outside the gap formed between the mobile phone and the mobile phone cover and used for hanging and binding the external-source (third-party) accessory. The thickness of the stand-alone type mobile phone sandwich sheet is controlled reasonably, and particularly, at least two sandwich pieces are disposed in the interspace and form one sandwich layer, in which the enhancing member is disposed to enhance the overall strength of the sandwich layer. 
     When a user needs to hang or bind a third-party accessory on the mobile phone, or when the user needs to fix the mobile phone, if the mobile phone per se has a mobile phone shell/cover already, the present product of the stand-alone type mobile phone sandwich sheet can be added very simply and conveniently for hanging, binding or fixing the third-party accessory or fixing the mobile phone per se, without changing the existing configuration of the user. 
     The stand-alone type mobile phone sandwich sheet can be independent of the mobile phone and the mobile phone cover, or can be fixed at an inner side (i.e. a side laminated with the mobile phone) of the mobile phone cover, thereby facilitating installation and removal. Although being a sheet-like structure member smaller in thickness, the stand-alone type mobile phone sandwich sheet is very firm by being disposed in the gap formed between the mobile phone and the mobile phone cover and by depending on a friction force between the sandwich sheet and the mobile phone and/or mobile phone cover, and can completely bear the self weight of the accessory after hanging or binding the third-party accessory. 
     In view of the stand-alone type mobile phone sandwich sheet being disposed in the gap formed between the mobile phone and the mobile phone cover, the present product will not destroy the overall style of the existing mobile phone/mobile phone cover of the user. 
     The stand-alone type mobile phone sandwich sheet is broad in applicability and can undergo cross use among multiple types of products. In the meantime, the stand-alone type mobile phone sandwich sheet is low in cost and easy to popularize and promote among mobile phone users.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention will be further illustrated below in combination with the accompanying drawings and the embodiments. 
     For the sake of description, “left”, “right”, “up” and “down” as mentioned in the context are consist with the directions of “left”, “right”, “up” and “down” in the drawings per se. It should be noted that the embodiments and the features therein in the present invention can be mutually combined in the absence of conflicts. 
     Embodiment 1 
     As shown in  FIG. 1 , the stand-alone type mobile phone sandwich sheet for securing accessories as described in the present embodiment makes use of a large-area interspace space between the mobile phone shell and the mobile phone. A sandwich piece  3  is disposed between the mobile phone cover  1  and the mobile phone  2 . Structurally speaking, the sandwich piece  3  includes a sandwich piece body  31  and an extension portion  32 ; and the sandwich piece body  31  and the extension portion  32  are preferably of an integral structure, or the sandwich piece body  31  and the extension portion  32  are spliced into a whole. The sandwich piece  3  is of a sheet-like structure member and fits an inner side of the mobile phone cover  1  in terms of external shape and size. The sandwich piece  3  is made from such material as a textile cloth, a PVC material, and a paper material, or can be made from a metal material, such as metal aluminum and an alloy. There is no strict limitation on the material for manufacturing the sandwich piece  3  in the present embodiment, and any slim sheet-like member meets the requirement of the present invention. 
     Preferably, the sandwich piece body  31  and the extension portion  32  are of an integral structure; and the extension portion  32  is formed by extending one end of the sandwich piece body  31  and is located outside the gap formed between the mobile phone  2  and the mobile phone cover  1 . 
     In addition to possibly being disposed in the gap between the mobile phone cover  1  and the mobile phone  2  independently, the sandwich piece  3  can be directly fixed at the inner side of the mobile phone shell/cover to be combined with the mobile phone shell/mobile phone cover as a whole. In such a way, the material selection of the sandwich piece  3  and the design of the sandwich layer  3  can be unnecessary. Preferably, one face of the sandwich piece  3  is directly stuck to a back face of the mobile phone, or an inner side of the mobile phone cover  1 , with a backing adhesive. 
     The extension portion  32  is used for hanging and binding a third-party (external-source) accessory. The extension portion  32  is provided with an accessory fixing mechanism (not marked in the drawings); and the accessory fixing mechanism is preferably a hole formed in the extension portion  32 , or a hook or a binding tie configured on the extension portion  32 . 
     The principle of the stand-alone type mobile phone sandwich sheet for securing accessories as described in the present embodiment is illustrated as follows: the contact between most of the existing mobile phones and the mobile phone shells/covers is extremely tight, the mobile phones are wrapped extremely firmly, and thus, the interspaces therebetween are very small. If a third-party slim object (the sandwich piece  3 ) having an external surface higher in friction coefficient is disposed between the two, the external force required for pulling out the third-party object (the sandwich piece  3 ) from the gap is far more than the gravity force of the mobile phone plus the mobile phone shell/cover, without detaching the mobile phone shell/cover. Further, a conclusion is obtained as follows: the third-party object (the sandwich piece  3 ) in a form as described above can be used for fixing other accessories or fixing the mobile phone per se. 
     Embodiment 2 
     As shown in  FIG. 2 , the stand-alone type mobile phone sandwich sheet for securing accessories as described in the present embodiment includes two sandwich pieces  3 , wherein the sandwich piece body  31  of one sandwich piece  3  is overlapped with the sandwich piece body  31  of the other sandwich piece  3 ; the extension portion  32  of one sandwich piece  3  is overlapped with the extension portion  32  of the other sandwich piece  3 ; and a sandwich layer is formed between the two sandwich pieces  3 . 
     The two sandwich pieces  3  are disposed to possibly reduce the deformation degree of the sandwich pieces  3  when the extension portions  32  are pulled with an external force, thereby further enhancing the overall strength of the stand-alone type mobile phone sandwich sheet. The description remained is the same as that described in Embodiment 1, and Embodiment 1 can be referred to, and may be optimized and improved on this basis. 
     Embodiment 3 
     As shown in  FIG. 3 , the stand-alone type mobile phone sandwich sheet for securing accessories as described in the present embodiment includes two sandwich pieces  3 , wherein the two sandwich pieces  3  form a sandwich layer. The sandwich layer is internally provided with an enhancing member  4 , which is made from a metal, wood or plastic material, and preferably, is made from an ultra-thin wood sheet material, a bamboo sheet material, a metal material, a plastic material and the like; the enhancing member  4  is fixed between the upper and lower two sandwich pieces  3  for preventing the present product from being reduced in deformation degree when pulled with an external force in a use process, thereby further reducing the detachment risk of the present product. For the convenience of implementation, the enhancing member  4  is preferably a sticker or an adhesive tape stuck between the two sandwich pieces  3 . The description remained is the same as that described in Embodiments 1 and 2, and Embodiments 1 and 2 can be referred to, and may be optimized and improved on this basis. 
     In the description of the present specification, the description of reference terms such as “embodiment”, “example”, “specific example”, or “some examples” is intended to indicate the inclusion of a specific method, device or feature as described by said embodiment or example into at least one embodiment or example of the present embodiment.
