[0071] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0072] Wood materials have strong designability due to their special surface texture and are often used in furniture finishes or high-end automotive interiors. When this wood material is used in the housing of electronic devices, it can provide a textured and differentiated appearance.

[0073] The wooden shell in the related art includes a stacked veneer layer, a film layer and a support layer, wherein the support layer is made of short fibers or filaments that are arranged in a directional or random manner and then reinforced by mechanical or thermal bonding methods. It has the advantages of being light, environmentally friendly, and economical.

[0074] However, due to the loose structure of wood materials, the use of a supporting layer made of short fibers or filaments in a directional or random arrangement will result in poor interlayer bonding and easy delamination of the wood shell when boiled, which limits its application in electronic equipment shells.

[0075] Based on this, the present disclosure provides a wooden shell, including a stacked veneer layer, a first adhesive film layer and a fabric base layer, wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner, which can improve the stability and durability of the fabric base layer structure, and is beneficial to improving the interlayer bonding strength between the fabric base layer and the veneer layer, solving the problem of easy delamination of the wooden shell when boiled in water, thereby helping to improve the service life of the wooden shell.

[0076] In an exemplary embodiment of the present disclosure, a wooden housing is provided. Figure 1 As shown, the shell includes a laminated veneer layer 1, a first adhesive film layer 2 and a fabric base layer 3; wherein the fabric base layer 3 is woven by warp yarns and weft yarns in a preset manner.

[0077] In this embodiment, the fabric base layer 3 is woven by warp yarns and weft yarns in a preset manner, which can improve the stability and durability of the fabric base layer 3 structure, and is beneficial to improving the interlayer bonding strength between the fabric base layer 3 and the veneer layer 1, solving the problem of easy delamination of the wooden shell after boiling.

[0078] The fabric base layer 3 is woven by warp yarns and weft yarns in a preset manner, which means that the warp yarns and weft yarns are cross-woven in a preset manner to form a mesh structure. For example, the warp yarns and weft yarns of the fabric base layer 3 are woven at a weaving angle of 85 to 95 degrees.

[0079] For example, the warp and weft of the fabric base layer 3 are woven at a weaving angle of 85 degrees. It is understandable that the weaving angles of the warp and weft can also be other values ​​within the above range, such as 90 degrees or 95 degrees. Among them, when the fabric base layer 3 is woven by the warp and weft at a weaving angle of 90 degrees, a tight grid structure can be formed, so the resulting fabric is usually relatively strong and sturdy. When this woven fabric base layer 3 is set on the veneer layer 1, it is not easy to delaminate after boiling, which is beneficial to improve the stability of the veneer shell structure.

[0080] In an exemplary embodiment of the present disclosure, the thickness ratio of the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 is 1:(0.1-0.3):(0.5-1.5).

[0081] In this embodiment, the thickness ratio of the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 is within the range of 1:(0.1-0.3):(0.5-1.5), which can achieve better comprehensive mechanical properties.

[0082] Exemplarily, the thickness ratio of the veneer layer 1 , the first adhesive film layer 2 and the fabric base layer 3 is 1:0.1:0.5.

[0083] It is understandable that the thickness ratio among the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 may also be other ratios within the above range, for example, the thickness ratio among the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 is 1:0.2:1 or 1:0.3:1.5.

[0084] In an exemplary embodiment of the present disclosure, the thickness of the veneer layer 1 is 0.2-0.3 mm; the thickness of the first adhesive film layer 2 is 0.03-0.05 mm; and the thickness of the fabric base layer 3 is 0.15-0.30 mm.

[0085] In this embodiment, by controlling the thickness of the veneer layer 1 and the fabric base layer 3, the weight of the shell can be reduced while ensuring the strength of the shell.

[0086] Exemplarily, the thickness of the veneer layer 1 is 0.2 mm; the thickness of the first adhesive film layer 2 is 0.03 mm; and the thickness of the fabric base layer 3 is 0.15 mm.

[0087] It is understandable that the thickness of the veneer layer 1, the first adhesive film layer 2 and the base fabric layer 3 may also be other values ​​within the above range. For example, the thickness of the veneer layer 1 is 0.25 mm; the thickness of the first adhesive film layer 2 is 0.04 mm; and the thickness of the base fabric layer 3 is 0.20 mm. Alternatively, the thickness of the veneer layer 1 is 0.3 mm; the thickness of the first adhesive film layer 2 is 0.05 mm; and the thickness of the base fabric layer 3 is 0.30 mm.

[0088] In an exemplary embodiment of the present disclosure, the veneer layer 1 includes one of natural solid wood and technical wood.

[0089] In this embodiment, the veneer layer 1 can be made of natural solid wood or technological wood. Natural solid wood refers to natural wood that has not been processed by modern processes such as gluing and laminating. Technological wood is wood that has been processed by modern processes such as splicing, gluing, laminating, etc. It is an artificially synthesized imitation solid wood product, and its surface also has the natural texture of wood. When natural solid wood or technological wood is used as the raw material of the veneer layer 1, it can present a good appearance texture.

[0090] In an exemplary embodiment of the present disclosure, Figure 1As shown, the wooden shell includes a laminated veneer layer 1, a first adhesive film layer 2, a fabric base layer 3, a second adhesive film layer 4 and a reinforcement layer 5, wherein the fabric base layer 3 is woven by warp yarns and weft yarns in a preset manner.

[0091] The arrangement and thickness of the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 in this embodiment are the same as those in the above embodiment and will not be described in detail. In this embodiment, the arrangement of the reinforcement layer 5 can improve the overall strength of the wooden shell, thereby facilitating the improvement of the service life of the wooden shell.

[0092] In an exemplary embodiment of the present disclosure, the thickness ratio of the veneer layer 1 to the reinforcement layer 5 is 1:(1.5-2.5).

[0093] In this embodiment, the provision of the reinforcement layer 5 can improve the overall strength of the shell. Compared with the veneer layer 1, if the thickness of the reinforcement layer 5 is too small, it is difficult to achieve the desired reinforcement effect; if the thickness of the reinforcement layer 5 is too large, the overall thickness of the shell will be too large or the overall weight will be too heavy. Therefore, when the thickness ratio of the veneer layer 1 to the reinforcement layer 5 is 1: (1.5-2.5), the overall strength of the wooden shell can be improved while meeting the design requirements of lightweight shell.

[0094] Exemplarily, the thickness ratio of the veneer layer 1 to the reinforcement layer 5 is 1:1.5.

[0095] It can be understood that the thickness ratio of the veneer layer 1 to the reinforcing layer 5 may also be other ratios within the above range, for example, the thickness ratio of the veneer layer 1 to the reinforcing layer 5 is 1:1.6, 1:2 or 1:2.5.

[0096] In an exemplary embodiment of the present disclosure, the reinforcing layer 5 includes a composite layer of one or both of an inorganic fiber layer and a resin layer. Both inorganic fiber and resin have good mechanical properties. In this embodiment, when the inorganic fiber layer and / or the resin layer are used as the reinforcing layer 5, the supporting strength can be provided for the shell.

[0097] Exemplarily, the inorganic fiber layer includes a composite layer of one or more of a glass fiber layer, a ceramic fiber layer, and a quartz fiber layer; the resin layer includes a composite layer of one or more of a polycarbonate layer, a phenolic resin layer, and an epoxy resin layer. For example, in order to improve the overall strength of the shell, a glass fiber layer can be selected as the reinforcing layer 5, and the glass fiber layer can be made of a glass fiber board; in order to reduce the overall weight of the shell, a polycarbonate layer can be selected as the reinforcing layer 5, and the polycarbonate layer can be made of a polycarbonate (PC) board.

[0098] It can be understood that the reinforcing layer 5 is not limited to a single material, but can also be composed of a composite of multiple materials. For example, a glass fiber layer and a polycarbonate layer are sequentially stacked on the second film layer 4, and the polycarbonate layer and the glass fiber layer can be bonded by a third film layer. Thus, the stacked glass fiber layer, the third film layer and the polycarbonate layer can be used as the reinforcing layer 5.

[0099] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the wooden shell includes a laminated veneer layer 1, a first adhesive film layer 2, a fabric base layer 3, and a paint film layer 6 laminated on the side of the veneer layer 1 away from the fabric base layer 3. The fabric base layer 3 is woven by warp yarns and weft yarns in a preset method.

[0100] Among them, the arrangement and thickness of the veneer layer 1, the first adhesive film layer 2 and the fabric base layer 3 are the same as those in the above embodiment and will not be repeated here. In this embodiment, by stacking the paint film layer 6 on the side of the veneer layer 1 away from the fabric base layer 3, on the one hand, the defects such as burrs on the surface of the veneer layer 1 can be covered to improve the appearance refinement of the shell; on the other hand, the setting of the paint film layer 6 can also make up for the defect of loose wood structure of the veneer layer 1, improve the surface scratch resistance of the veneer, and improve the surface hardness of the shell. In addition, according to the appearance requirements, a paint film layer 6 with different appearance effects, such as matte effect, glossy effect, etc., can be selected to improve the appearance texture of the shell.

[0101] It can be understood that in order to simultaneously improve the surface hardness and strength of the shell, in an exemplary embodiment of the present disclosure, Figure 1 As shown, the wooden shell includes a laminated veneer layer 1, a first adhesive film layer 2, a fabric base layer 3, a second adhesive film layer 4, a reinforcement layer 5, and a paint film layer 6 laminated on a side of the veneer layer 1 away from the fabric base layer 3.

[0102] In this embodiment, one side of the veneer layer 1 is provided with supporting strength by the woven cloth base layer 3 and the reinforcement layer 5, while the other side of the veneer layer 1 is provided with surface hardness by the paint film layer 6. The resulting wooden shell not only has the appearance and texture of natural wood material, but also has good mechanical properties, good durability and service life.

[0103] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the paint film layer 6 includes a primer layer 61 , a middle paint layer 62 , a color paint layer 63 and a top paint layer 64 which are stacked on the veneer layer 1 .

[0104] In this embodiment, the primer layer 61 can seal the loose wood structure of the veneer layer 1 and improve its adhesion to other paint layers. The middle paint layer 62 can fill the holes and textures of the veneer layer 1 to improve the flatness, vividness and fullness of the paint film layer 6. The color paint layer 63 can give the paint film color to enrich the appearance of the shell. The topcoat layer 64 can improve the strength and surface hardness of the veneer layer 1 to improve the mechanical properties of the paint film layer 6. By stacking the primer layer 61, the middle paint layer 62, the color paint layer 63 and the topcoat layer 64, the appearance texture of the shell can be enriched, the surface adhesion and hardness of the shell can be improved, and the practicality and durability of the shell can be improved.

[0105] In order to further improve the water resistance of the wooden shell, in addition to respectively arranging the reinforcing layer 5 and the paint film layer 6 on the two surfaces of the veneer layer 1, it is also necessary to arrange the oil edge layer 7 on the side of the veneer layer 1 to prevent water from entering the edge of the wooden shell.

[0106] In an exemplary embodiment of the present disclosure, Figure 2 As shown, the wooden shell includes a stacked veneer layer 1, a first adhesive film layer 2, a cloth base layer 3, a second adhesive film layer 4, a reinforcement layer 5, and an oil edge layer 7 arranged around the side of the veneer layer 1, wherein the oil edge layer 7 is arranged between the cloth base layer 3 and the second adhesive film layer 4.

[0107] In this embodiment, the side of the veneer layer 1 can be sealed by the oil edge layer 7 surrounding the side of the veneer layer 1 to improve the water resistance of the veneer layer 1. The setting method of the oil edge layer 7 is related to the structure of the reinforcement layer 5. When the reinforcement layer 5 is a frame structure, for example, when the reinforcement layer 5 is a fiberglass board with a frame, it is necessary to firstly surround the side of the veneer layer 1 with the oil edge layer 7 before setting the second adhesive film layer 4 on the fabric base layer 3, and then set the second adhesive film layer 4 and the reinforcement layer 5 on the fabric base layer 3 on which the oil edge layer 7 has been set, so that the oil edge layer 7 is set between the fabric base layer 3 and the second adhesive film layer 4.

[0108] It can be understood that when the reinforcement layer 5 is a frameless structure, for example, the reinforcement layer 5 is a frameless fiberglass board, after the reinforcement layer 5 and the paint film layer 6 are arranged on the veneer layer 1, the oil edge layer 7 is arranged around the side of the veneer layer 1, so that the oil edge layer 7 is arranged on the paint film layer 6.

[0109] In an exemplary embodiment of the present disclosure, the wooden shell includes a stacked veneer layer 1, a first adhesive film layer 2, a cloth base layer 3, a second adhesive film layer 4, a reinforcement layer 5, a paint film layer 6 stacked on the side of the veneer layer 1 away from the cloth base layer 3, and an oil edge layer 7 surrounding the side of the veneer layer 1, wherein the oil edge layer 7 is arranged on the paint film layer 6.

[0110] In this embodiment, by arranging the fabric base layer 3 woven by warp and weft in a preset manner on the veneer layer 1, the stability and durability of the fabric base layer 3 structure can be improved, which is conducive to improving the interlayer bonding force between the fabric base layer 3 and the veneer layer 1; the stability of the overall structure of the shell can be improved by arranging the reinforcement layer 5; the surface hardness of the shell can be improved by arranging the paint film layer 6; the side of the veneer layer 1 can be sealed by the oil edge layer 7 surrounding the side of the veneer layer 1 to improve the water resistance of the veneer layer 1. The wooden shell thus obtained not only has the appearance and texture of natural wood materials, but also has the advantages of good interlayer bonding force, high surface hardness and not easy to delaminate when boiled.

[0111] In an exemplary embodiment of the present disclosure, the thickness of the oil edge layer 7 is 15-25 μm. For example, the thickness of the oil edge layer 7 is 15 μm, 20 μm or 25 μm.

[0112] If the thickness of the oil edge layer 7 is too low, it is difficult to achieve the required waterproof function; if the thickness of the oil edge layer 7 is too high, it will affect the bonding precision of the subsequent process. In this embodiment, when the thickness of the oil edge layer 7 is set to 15-25 μm, it can meet the water resistance and processing requirements of the subsequent process.

[0113] In an exemplary embodiment of the present disclosure, a method for processing a wooden shell is provided, such as Figure 3 As shown, the processing method of the wooden shell in this embodiment includes:

[0114] S110, a first adhesive film layer and a fabric base layer are sequentially stacked on the wood veneer layer to obtain a wooden shell; wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner.

[0115] In this step, the raw material of the wood cortex layer can be natural solid wood or technical wood. The following takes natural solid wood as an example to illustrate the method for making the raw material of the wood cortex layer.

[0116] The veneer raw material is obtained by steaming, slicing, drying, leveling, inspecting, wrapping, light-fast treatment, bleaching and dyeing, cleaning, waterproofing, drying, leveling, cutting, compounding, trimming, grinding and cutting the natural solid wood in sequence. The specific operation steps of each process in the above-mentioned processing are conventional methods in the art and are not described in detail here.

[0117] In this embodiment, the base fabric is woven by warp yarns and weft yarns in a preset manner, which means that the warp yarns and weft yarns are cross-woven in a preset manner to form a mesh structure. Exemplarily, the warp yarns and weft yarns of the base fabric are woven at a weaving angle of 85 to 95 degrees.

[0118] In this step, the function of the first adhesive film layer is to connect the veneer layer and the fabric base layer together. Therefore, any adhesive that has a bonding effect on the veneer layer and the fabric base layer can be used as the raw material of the first adhesive film layer. However, since the veneer layer has a loose wood structure, when the adhesive is in liquid state, the solvent of the adhesive may penetrate into the interior of the veneer layer, resulting in a lower content of effective bonding components on the surface of the veneer layer, affecting the bonding strength between the veneer layer and the fabric base layer, and may also increase the unevenness of the fabric base layer, affecting the aesthetics of the product. Therefore, a solid adhesive can be used as the raw material of the first adhesive film layer.

[0119] Exemplarily, the first adhesive film layer is formed by curing the first adhesive film. The first adhesive film may be a hot melt adhesive, which may be cured by heat curing, moisture curing, radiation curing, etc. The hot melt adhesive may be a polyester hot melt adhesive, such as a thermoplastic polyurethane (TPU) hot melt adhesive, a reactive polyurethane (PUR) hot melt adhesive, etc.

[0120] For example, a first adhesive film is covered on the veneer layer, and then a cloth base layer is covered on the first adhesive film, and thermal curing is performed at a temperature of 110-120° C. to form a first adhesive film layer, and the cloth base layer and the veneer layer are bonded through the first adhesive film layer.

[0121] In an exemplary embodiment of the present disclosure, Figure 4 As shown, the processing method of the wooden shell in this embodiment includes:

[0122] S210, sequentially stacking a first adhesive film layer and a fabric base layer on the veneer layer to obtain a first intermediate material; wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner.

[0123] This step is the same as the implementation of step S110 in the above embodiment, and will not be described again here.

[0124] S220, a second adhesive film layer and a reinforcing layer are laminated on a side of the cloth base layer of the first intermediate material away from the first adhesive film layer to obtain a wooden shell.

[0125] In this step, the function of the second adhesive film layer is similar to that of the first adhesive film layer; the second adhesive film layer is used to connect the first intermediate material and the reinforcing layer together, so any adhesive that has a bonding effect between the first intermediate material and the reinforcing layer can be used as the raw material of the second adhesive film layer. The raw material of the second adhesive film layer can be the same as or different from that of the first adhesive film layer, and can be selected according to actual use requirements, which will not be repeated here.

[0126] Exemplarily, the second adhesive film layer is formed by curing the second adhesive film. For example, a polyester hot melt adhesive is used as the second adhesive film. The second adhesive film is coated on the cloth base of the first intermediate material, and then the reinforcement layer is coated on the second adhesive film, and thermally cured at a temperature of 110-120° C. to form the second adhesive film layer, and the first intermediate material and the reinforcement layer are bonded through the second adhesive film layer.

[0127] In this step, the reinforcing layer is used to provide support strength for the wooden shell, and can be a composite layer of one or both of an inorganic fiber layer and a resin layer, for example, a glass fiber board or a polycarbonate board is selected as the raw material of the reinforcing layer.

[0128] In an exemplary embodiment of the present disclosure, Figure 5 As shown, the processing method of the wooden shell in this embodiment includes:

[0129] S310, sequentially stacking a first adhesive film layer and a fabric base layer on the veneer layer to obtain a first intermediate material; wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner.

[0130] S320 , stacking a second adhesive film layer and a reinforcement layer on a side of the fabric base layer of the first intermediate material away from the first adhesive film layer to obtain a second intermediate material.

[0131] The implementation of step S310 and step S320 in this embodiment is the same as that of step S210 and step S220 in the above embodiment, and will not be repeated here.

[0132] S330, a paint film layer is laminated on a side of the wood cortex layer of the second intermediate material away from the cloth base layer to obtain a wooden shell.

[0133] In this step, after the first intermediate material is attached to the reinforcing layer, the second intermediate material can be punched out with a die cutter as needed to obtain a sample of the desired size and shape.

[0134] In this embodiment, the surface hardness of the wooden shell can be increased by providing the paint film layer, thereby improving the scratch resistance of the surface.

[0135] The paint film layer can be formed by curing the paint. For example, the paint is applied to the side of the wood veneer layer away from the cloth base layer, and after curing, the paint film layer is formed.

[0136] In an exemplary embodiment of the present disclosure, Figure 6 As shown, the processing method of the wooden shell in this embodiment is a further limitation of step S330 in the above embodiment, including:

[0137] S410, a primer layer, a mid-paint layer, a color paint layer and a top paint layer are stacked on a side of the wood layer of the second intermediate material away from the cloth base layer, and the primer layer, the mid-paint layer, the color paint layer and the top paint layer form the paint film layer.

[0138] In this step, by stacking the primer layer, the middle paint layer, the color paint layer and the top paint layer, the appearance texture of the shell can be enriched, the surface adhesion and hardness of the shell can be improved, so as to improve the practicality and durability of the shell.

[0139] In an exemplary embodiment of the present disclosure, Figure 7 As shown, the processing method of the wooden shell in this embodiment is a further limitation of step S410 in the above embodiment, including:

[0140] S510, coating a primer on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, and baking at a temperature of 55-65° C. for 6-15 minutes to form a primer layer.

[0141] S520, apply a mid-coat on the primer layer and bake at a temperature of 45-55°C for 3-10 minutes to form a mid-coat layer.

[0142] S530, apply color paint on the middle paint layer, and bake at a temperature of 55-65°C for 6-15 minutes to form a color paint layer.

[0143] S540, apply topcoat on the color paint layer, and bake at a temperature of 45-55°C for 3-10 minutes to form a topcoat layer.

[0144] Since the veneer is easy to shrink at high temperature, a low-temperature curing and fast drying process is required when the veneer layer is sprayed. In this embodiment, when selecting the types of primer, mid-coat, color paint and topcoat, it is necessary to use a paint that can be cured at low temperature, such as a low-temperature curing polyurethane (PU) primer, an ultraviolet light curing (UV) mid-coat, etc. In this way, when the veneer layer is sprayed, the shrinkage of the veneer can be reduced, thereby improving the aesthetics of the shell.

[0145] Exemplarily, a primer layer, a mid-coat layer, a color paint layer and a top coat layer are stacked on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, including:

[0146] A primer is applied on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, and baked at a temperature of 55° C. for 15 minutes to form a primer layer.

[0147] A mid-coat is applied on the primer layer and baked at 45°C for 10 minutes to form a mid-coat layer.

[0148] Color paint is applied on the middle paint layer and baked at 55°C for 15 minutes to form a color paint layer.

[0149] A topcoat is applied on the color paint layer and baked at 45°C for 10 minutes to form a topcoat layer.

[0150] It is understandable that the process conditions for coating the varnish on the wood veneer layer may also be other values ​​within the above range, for example:

[0151] A primer is applied on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, and baked at a temperature of 60° C. for 10 minutes to form a primer layer.

[0152] A mid-coat is applied on the primer layer and baked at 50°C for 5 minutes to form a mid-coat layer.

[0153] Color paint is applied on the middle paint layer and baked at 60°C for 10 minutes to form a color paint layer.

[0154] A topcoat is applied on the color paint layer and baked at 50°C for 5 minutes to form a topcoat layer.

[0155] or:

[0156] A primer is applied on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, and baked at a temperature of 65° C. for 6 minutes to form a primer layer.

[0157] A mid-coat is applied on the primer layer and baked at 55°C for 3 minutes to form a mid-coat layer.

[0158] Color paint is applied on the middle paint layer and baked at 65°C for 6 minutes to form a color paint layer.

[0159] A topcoat is applied on the color paint layer and baked at 55°C for 3 minutes to form a topcoat layer.

[0160] The surface strength of the shell can be improved by spraying the surface of the wood veneer layer multiple times. In order to further improve the adhesion of the paint film and increase the surface hardness of the shell, the middle paint layer can be polished between forming the middle paint layer and the color paint layer.

[0161] Exemplarily, a paint film layer is laminated on a side of the wood cortex layer of the second intermediate material away from the cloth base layer, including:

[0162] Apply primer on the side of the wood cortex layer of the second intermediate material away from the cloth base layer, and bake at a temperature of 55-65° C. for 6-15 minutes to form a primer layer;

[0163] Apply the middle paint on the primer layer and bake at 45-55℃ for 3-10min to form the middle paint layer;

[0164] Grind the midcoat;

[0165] Apply color paint on the polished middle paint layer, and bake at 55-65℃ for 6-15min to form a color paint layer;

[0166] Apply topcoat on the color paint layer and bake at 45-55°C for 3-10 minutes to form a topcoat layer.

[0167] In this embodiment, by performing a surface treatment process of four coatings, four bakings and polishing on the surface of the veneer layer, the burrs on the surface of the veneer layer can be covered, thereby improving the surface scratch resistance of the shell and making the surface hardness of the shell reach 1H.

[0168] In order to further improve the water resistance of the wooden shell, in addition to setting a reinforcement layer and a paint film layer on the two surfaces of the wood veneer layer, an oil edge layer needs to be set on the side of the wood veneer layer to prevent water from entering the edge of the wooden shell. The setting method of the oil edge layer is related to the structure of the reinforcement layer.

[0169] When the reinforcing layer is a structure with a surrounding bone, for example, when the reinforcing layer is a fiberglass board with a surrounding bone, in an exemplary embodiment of the present disclosure, Figure 8 As shown, the processing method of the wooden shell in this embodiment includes:

[0170] S610, a first adhesive film layer and a fabric base layer are sequentially stacked on the veneer layer to obtain a first intermediate material; wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner.

[0171] This step is the same as the implementation of step S310 in the above embodiment, and will not be described again here.

[0172] S620, an oil edge layer is arranged around the side of the wood veneer layer.

[0173] In this step, since the thickness of the veneer layer is relatively small, when the oil edge layer is arranged around the side of the veneer layer, the oil edge layer will also be wrapped around the cloth base layer and the side of the veneer layer away from the cloth base layer. This arrangement can prevent water from entering the edge of the veneer layer, thereby achieving a good waterproof effect.

[0174] S630, a second adhesive film layer and a reinforcing layer are laminated on a side of the fabric base layer away from the first adhesive film layer to obtain a wooden shell.

[0175] This step is basically the same as the implementation of step S210 in the above embodiment, except that, since an oil edge layer is first arranged around the side of the veneer layer before the second adhesive film layer and the reinforcement layer are arranged, the oil edge layer is arranged between the cloth base layer and the second adhesive film layer.

[0176] In this embodiment, since the reinforcing layer is a fiberglass board with a surrounding frame structure, it is necessary to provide an oil edge layer on the side of the veneer layer before attaching the reinforcing layer to prevent water from entering the edge of the wooden shell and improve the water resistance of the shell.

[0177] When the reinforcement layer is a structure without a surrounding frame, for example, when the reinforcement layer is a fiberglass board without a surrounding frame, in an exemplary embodiment of the present disclosure, Fig. 9 As shown, the processing method of the wooden shell in this embodiment includes:

[0178] S710, sequentially stacking a first adhesive film layer and a fabric base layer on the veneer layer to obtain a first intermediate material; wherein the fabric base layer is woven by warp yarns and weft yarns in a preset manner.

[0179] S720 , stacking a second adhesive film layer and a reinforcement layer on a side of the fabric base layer of the first intermediate material away from the first adhesive film layer to obtain a second intermediate material.

[0180] S730, a paint film layer is laminated on a side of the wood cortex layer of the second intermediate material away from the fabric base layer to obtain a third intermediate material.

[0181] The implementation of steps S710 to S730 in this embodiment is the same as that of steps S310 to S330 in the above embodiment, and will not be repeated here.

[0182] S740, an oil edge layer is disposed around the side of the wood cortex layer of the third intermediate material, so that the oil edge layer is disposed on the paint film layer to obtain a wooden shell.

[0183] In this embodiment, since the reinforcement layer is a fiberglass board without a surrounding frame structure, the oil edge layer can be set on the side of the veneer layer after the reinforcement layer and the paint film layer are set on the shell. Compared with the process of setting the oil edge layer first and then setting the reinforcement layer, the method of this embodiment has better processing refinement and is conducive to improving the appearance of the shell.

[0184] Exemplarily, the side of the wood cortex layer is surrounded by an oil edge layer, which includes:

[0185] The ink is coated on the side of the wood cortex layer, baked at a temperature of 40-50°C for 20-40 minutes, and then baked at a temperature of 70-80°C for 50-70 minutes to form an oil edge layer.

[0186] The type of ink is not limited, and transparent or colored water-based ink can be used. By coating the side of the veneer layer with ink, water can be prevented from entering the edge of the veneer layer, and defects such as burrs on the edge of the veneer layer can be modified.

[0187] In this embodiment, the veneer layer is placed in an oil edge jig, and ink is applied to the four sides of the veneer layer by an oil edge machine and then dried, and this is repeated 2-3 times to form an oil edge layer with a thickness of 15-25 μm. After the oil edge layer is coated, the oil edge glue overflow problem is checked to complete the processing of the wooden shell.

[0188] Exemplarily, ink is coated on the side of the wood cortex layer, baked at 40° C. for 40 minutes, and then baked at 70° C. for 70 minutes to form an oil edge layer.

[0189] It is understandable that the process conditions for forming the oil edge layer may also be other values ​​within the above range, for example:

[0190] Ink is applied to the side of the wood veneer layer, baked at 45°C for 30 minutes, and then baked at 75°C for 60 minutes to form an oil edge layer.

[0191] Ink is applied to the side of the wood cortex layer, baked at 50°C for 20 minutes, and then baked at 80°C for 50 minutes to form an oil edge layer.

[0192] In an exemplary embodiment of the present disclosure, an electronic device is provided, and the electronic device is, for example, a mobile phone, a laptop computer, a tablet computer, and a wearable device.

[0193] The electronic device comprises the shell, and the wooden material can be applied to the electronic device through the shell, thereby improving the aesthetics of the electronic device.
