[0023] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0025] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0026] According to an embodiment of the present disclosure, the utility model provides a housing with an integrated logo. Figure 1-2 As shown, the housing with an integrated logo includes a first carbon fiber material layer 1 and a second carbon fiber material layer 2 which are stacked in sequence from top to bottom, the second carbon fiber material layer is provided with at least one layer, and a logo embroidery layer 3 is also integrated at a set position of the first carbon fiber material layer 1, and the logo embroidery layer 3 penetrates the first carbon fiber material layer 1 in the thickness direction.

[0027] In this embodiment, the first carbon fiber material layer 1 includes resin and carbon fiber cloth impregnated in the resin.

[0028] The housing with integrated logo can be specifically applied to the housing of electronic devices, including but not limited to laptop computers, mobile phones, and pads. During hot pressing, the shape of the housing can be adaptively adjusted according to the shape of the specific application product. For example, the housing with integrated logo can be applied to part A of a laptop computer, which is used as an example for illustrative explanation.

[0029] Since the A-part of a laptop has always pursued the ultimate light and thin texture, we insist on using carbon fiber materials as A-parts. In view of the defect of weakened appearance surface strength caused by the split groove attachment method of the logo on the existing A-parts, this application will first use embroidery to combine and fix the logo with the carbon fiber material, and then use a hot pressing process to form the logo and the carbon fiber material into one piece, so as to obtain a notebook A-part with an integrated logo. Therefore, realizing an integrated logo design on carbon fiber materials can meet the appearance effect of the notebook A-part while maintaining the high strength characteristics of the A-part, and enhance the user's experience of the product.

[0030] In addition, the implementation method of integrating the carbon fiber material and the logo in this application is more environmentally friendly, in line with the sustainable product development strategy, bringing users a novel appearance experience and enhancing the competitiveness of the product.

[0031] In one embodiment, again referring to Figure 1-2 The housing with integrated logo further comprises a foaming material layer 4, and the weight of the housing can be reduced by arranging the foaming material layer 4. And housings with different layer structures can be obtained by arranging the foaming material layer 4 at different positions.

[0032] For example, refer again to Figure 2 In this embodiment, a housing with an integrated logo also includes a foam material layer 4, and the foam material layer 4 is provided with one layer. When the second carbon fiber material layer 2 is provided with one layer, the foam material layer 4 is provided between the first carbon fiber material layer 1 and the second carbon fiber material layer 2.

[0033] Alternatively, the housing with an integrated logo in this embodiment further includes a foam material layer 4. When the second carbon fiber material layer 2 has two or more layers, the foam material layer 4 is disposed between the first carbon fiber material layer 1 and the second carbon fiber material layer 2.

[0034] Also, refer to Figure 1 In this embodiment, a housing with an integrated logo further includes a foam material layer 4 . When the second carbon fiber material layer 2 is provided with two layers, the foam material layer 4 is provided between the two second carbon fiber material layers 2 .

[0035] The foam material layer 4 can reduce the weight of the housing. For example, the foam material layer 4 can be made of foamed PP material.

[0036] In this embodiment, the foam material layer 4, the first carbon fiber material layer 1, the second carbon fiber material layer 2 and the logo embroidery layer 3 are formed by heat pressing to obtain the housing.

[0037] In one embodiment, Figure 1-2As shown, the housing with integrated logo also includes a protective coating 5, which is provided on the carbon fiber material layer with the logo embroidery layer. Figure 1-2 As shown, the protective coating 5 is disposed on the first carbon fiber material layer 1. A layer of translucent protective coating 5 is coated on the surface of the first carbon fiber material layer 1 to effectively protect the surface of the housing.

[0038] According to an embodiment of the utility model, a method for preparing a housing with an integrated logo is provided, the method comprising: providing a first carbon fiber cloth, pre-impregnating the surface of the first carbon fiber cloth with a resin, wherein the resin accounts for 15 to 30 wt% of the mass of the first carbon fiber cloth;

[0039] Embroidering a logo on the first carbon fiber cloth soaked in resin at a set position, and the embroidered logo penetrates the first carbon fiber cloth in a thickness direction;

[0040] At least one second carbon fiber cloth is provided, and the second carbon fiber cloth is coated with resin and then laminated on the first carbon fiber cloth, so that the logo of the first carbon fiber cloth is exposed, and the casing is obtained by hot pressing and molding.

[0041] The present application first provides a first carbon fiber cloth woven from carbon filaments, then impregnates it with resin, then uses embroidery to combine and fix the logo with the first carbon fiber cloth, then provides at least one second carbon fiber cloth woven from carbon filaments, and coats the second carbon fiber cloth with resin and stacks it on the first carbon fiber cloth, and finally uses a hot pressing process to obtain a housing in which the logo and the carbon fiber material are integrally formed. The housing prepared by this method avoids damage to the overall appearance of the housing, effectively maintains the high strength of the housing, and provides a novel appearance effect for further creating light and thin products.

[0042] The surface of carbon fiber cloth woven from carbon fiber filaments is relatively loose and cannot be directly embroidered. It is necessary to pre-impregnate the surface with resin to increase its bonding strength. Setting the proportion of resin to 15-30wt% is beneficial to subsequent embroidery operations.

[0043] If the resin content is too small, less than 15wt%, the carbon fiber fibers in the carbon fiber cloth are relatively loose and easy to loosen during embroidery. If the resin content is too high, greater than 30wt%, the surface of the carbon fiber cloth will be too hard, and the needle will not be able to embroider during embroidery. In severe cases, the needle will break, affecting the beauty and efficiency of the embroidery results.

[0044] Among them, the resin is used as an adhesive that can effectively combine the layers. In order to maintain the green and environmental protection concept of the product, the resin is preferably an environmentally friendly resin, such as epoxy resin.

[0045] In this embodiment, when the surface of the first carbon fiber cloth is impregnated with resin, the required temperature is 120-130°C.

[0046] In this embodiment, the temperature during hot pressing is 120-130°C and the pressure is 4-4.5 kgf / cm2.

[0047] At present, the hot press molding machine is a hot press machine suitable for hot press molding of composite materials. Its working principle is: first put the prepreg into the mold, then heat the mold to a certain temperature through the heating system, and finally press the material in the mold through the pressure control system. The entire processing process requires strict control of parameters such as temperature, pressure and molding time to ensure the quality and performance consistency of the product.

[0048] Therefore, the casing obtained by the preparation method of the present application is illustrated by taking laptop computer part A as an example. During preparation, a mold is prepared based on part A using existing known technology, a mold release agent is first applied to the mold, and then the first carbon fiber cloth with logo embroidery is laid on the mold, and then two second carbon fiber cloths coated with resin are laid on the first carbon fiber cloth and a layer of foamed PP material is laid between the two second carbon fiber cloths, and then hot pressing is performed to form part A. The specific operation steps during hot pressing can be implemented using existing known technologies and will not be repeated here.

[0049] In one embodiment, embroidering a logo on the first carbon fiber cloth soaked with resin at a set position includes:

[0050] Providing a base frame, and attaching the elastic film flatly to the base frame;

[0051] Laying the first carbon fiber cloth impregnated with resin flat on the film;

[0052] A layer of elastic film is covered on the surface of the first carbon fiber cloth to fix and flatten the first carbon fiber cloth;

[0053] A logo position comparison jig is provided, and the position of the base frame is adjusted based on the logo position comparison jig to determine the logo position and complete the logo embroidery based on the logo color requirements. After the embroidery is completed, the upper and lower layers of the film are separated.

[0054] In order to prevent the deformation of the carbon fiber cloth during the embroidery process, a sandwich covering design is used to fix the carbon fiber cloth, and the sandwich of the fixed carbon fiber cloth has a certain toughness and embroidery needle penetration. Therefore, it is necessary to make a reusable base frame, such as Figure 3As shown, the base frame is a frame-type structure. Specifically, the base frame 6 includes a frame 61 with a hollow interior and a clamping member 62. The clamping member 62 is a strip-shaped structure. The clamping member 62 is sleeved outside the frame 61 and the two ends of the clamping member 62 are threadedly fixed by screws 63. The clamping force of the clamping member 62 on the frame 61 is adjusted by rotating the screws 63. The frame 61 and the clamping member 62 cooperate to clamp and fix the film and the carbon fiber cloth. The base frame 6 is made of aluminum alloy, which has the advantages of lightness and high strength.

[0055] An elastic film, such as a pressure-sensitive adhesive polypropylene film (PP or BOPP), is attached and fixed to the frame of the base to provide elastic support at the bottom, and the carbon fiber cloth is laid flat on the film, and then a pressure-sensitive adhesive polypropylene film is covered on the carbon fiber cloth to fix the carbon fiber cloth. The position of the base frame is adjusted and the logo embroidery position is determined by the logo position comparison jig. The logo formed after the logo embroidery is completed will clamp part of the film in it. On the one hand, the film is elastic and can be easily separated from the carbon fiber cloth. On the other hand, since the film is a transparent structure, even if a small amount of film is clamped in the logo, it will not affect the subsequent hot pressing and the appearance of the finished product. Among them, the logo position comparison jig is generally a plate-like structure with a logo on it. The position of the logo is based on the logo position of the finished casing. Therefore, based on the logo position comparison jig, the position of the base frame can be adjusted and the logo embroidery position can be determined, so that the logo position on the formed casing can be determined, which keeps the logo position on the finished casing consistent in large-scale production.

[0056] In one embodiment, the preparation method further comprises, after the hot pressing, coating a protective coating on the surface of the first carbon fiber cloth with the logo embroidery. Coating the protective coating is beneficial to the appearance protection of the product.

[0057] On the other hand, the present disclosure also provides an electronic device, including a housing with integrated logo in any one of the above embodiments. Therefore, the housing with integrated logo can be used for the A part of a notebook computer, the housing of a pad, and the housing of a mobile phone.

[0058] Electronic devices with a housing with an integrated logo can meet the appearance requirements while maintaining the high strength characteristics of the housing, meet users' requirements for housing integration, and enhance users' experience of the product.
