[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Example 1

[0025] Reference Figure 1-2 A scratch-resistant polycarbonate film comprises a base layer 1, an adhesive layer 2 and a receiving layer 3, wherein the adhesive layer 2 is arranged on one side of the base layer 1, the receiving layer 3 is arranged on one side of the adhesive layer 2, a scratch-resistant part is assembled on one side of the receiving layer 3, the scratch-resistant part comprises a scratch-resistant conductive coating 4 and a touch conductive layer 5, the scratch-resistant conductive coating 4 is arranged on one side of the receiving layer 3, and the touch conductive layer 5 is bonded to the top of the scratch-resistant conductive coating 4.

[0026] The bottom edge of the base layer 1 is encapsulated with a encapsulation strip 6, and the top edge of the touch conductive layer 5 is also encapsulated with a encapsulation strip 6. The adhesive layer 2 and the anti-scratch conductive coating 4 are both connected to the encapsulation strip 6. The arrangement of the encapsulation strip 6 can increase the structural strength of the film. At the same time, the sides of the encapsulation strip 6 are in contact with the receiving layer 3.

[0027] The receiving layer 3 is composed of a polycarbonate layer and a support layer. The polycarbonate layer has the advantages of high transparency, high impact resistance, good insulation and flame retardancy, while the main function of the support layer is to prevent the film from being pressed and dented, which is crucial to maintaining the stability and durability of the entire structure. At the same time, the support layer can also prevent dust, moisture or pollutants in the external environment from entering the multi-layer structure to avoid reducing the reliability of the structure.

[0028] Metal powder particles are arranged on the inner side of the support layer, which can increase the support strength of the film.

[0029] Example 2

[0030] Embodiment 1 is further optimized, specifically, as Figure 3 As shown, auxiliary parts are installed between the scratch-resistant conductive coating 4 and the packaging strip 6 .

[0031] The auxiliary parts include a transparent tear strip 7 and a transparent tear head 8. The transparent tear strip 7 is fixed to one end corner of the packaging strip 6 on the touch conductive layer 5. The transparent tear strip 7 is located between the touch conductive layer 5 and the anti-scratch conductive coating 4. A transparent tear head 8 is fixed to one end of the transparent tear strip 7. The transparent tear head 8 is applied to the outside of the base layer 1, the adhesive layer 2 and the supporting layer 3. Since the transparent tear strip 7 and the transparent tear head 8 are transparent, they do not hinder the use of the device on the screen of the mechanical device. At the same time, after the touch conductive layer 5 is torn off, the function of the touch conductive layer 5 is maintained by providing the anti-scratch conductive coating 4, so that the touch conductive layer 5 can maintain the normal function of the film when scratches occur.

[0032] From the above, we can know that:

[0033] The utility model is aimed at the technical problem that the existing technology, when used on the screen of mechanical equipment, cannot generate stable touch feedback if the first substrate layer on the outer side of the surface is scratched and damaged, and a new film needs to be replaced to maintain the normal function of the film, making the anti-scratch effect less than ideal, and there is room for improvement; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solutions is:

[0034] During use, when the touch conductive layer 5 is damaged, the transparent tear strip 7 is pulled upward by the transparent tear head 8, so that the moving trajectory of the transparent tear strip 7 remains in an arc shape. Since one end of the transparent tear strip 7 is connected to the packaging strip 6, and the packaging strip 6 is connected to the touch conductive layer 5, when the transparent tear strip 7 generates a tearing force, the touch conductive layer 5 is quickly separated from the scratch-resistant conductive coating 4, and the normal touch feedback function of the entire film is maintained by the scratch-resistant conductive coating 4.

[0035] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:

[0036] 1. The present invention adopts the structural design of the anti-scratch part and the auxiliary part, so that when the touch conductive layer 5 is scratched and broken, the touch conductive layer 5 can be quickly torn off, and the normal touch feedback function is maintained by the anti-scratch conductive coating 4, thereby improving the safety of the present device.

[0037] 2. The utility model adopts the structural design of the receiving layer 3 so that the device can enhance the tensile and compressive resistance of the film, which is convenient for use.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
