Description

Technical Field

[0001] The present application relates to the field of panel technology, and in particular to a housing and an electronic device. Background Art

[0002] In order to improve the appearance of the product and vividly indicate the product function, a decorative panel is usually pasted on the surface of the product shell. In order to reduce costs, the decorative panel is usually made of a flexible film with a thickness of less than 1.2 mm.

[0003] In the related art, when pasting the flexible film, a full adhesive backing solution is usually selected to avoid problems such as uneven appearance and warping of the product after bonding due to insufficient bonding area.

[0004] However, the full adhesive bonding solution will cause the gases that are not exhausted during the bonding process, as well as the gases volatilized inside non-metallic materials (such as plastics), to accumulate on the bonding surface and cannot be discharged. The residual gases and waste gases will slowly gather and expand under the influence of temperature, and when the expansion pressure increases to a level greater than the adhesive strength of the adhesive and the material rigidity of the film panel itself, problems such as bubbles and hollows will appear on the product surface, affecting the product's appearance and bonding performance.

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] The present application embodiment provides a housing, such as Figure 1 and Figure 2 As shown, the shell includes a bottom shell layer 1, an adhesive layer 2, and a flexible film layer 3; the adhesive layer 2 is bonded to one side of the bottom shell layer 1, and the flexible film layer 3 is located on the side of the adhesive layer 2 away from the bottom shell layer 1, and is bonded to the adhesive layer 2; there is at least one airway groove 4 between the bottom shell layer 1 and the adhesive layer 2, and / or between the adhesive layer 2 and the flexible film layer 3, and the airway groove 4 has an exhaust port 41, and the exhaust port 41 is exposed relative to the adhesive layer 2 to communicate with the outside world.

[0048] The shell provided in the embodiment of the present application is provided with an airway groove 4 inside the shell, and the airway groove 4 is connected to the outside through the exhaust port 41, so that when the bottom shell layer 1 or the flexible film layer 3 is bonded to the adhesive layer 2, the gas at the bonding surface inside the shell can be discharged from the exhaust port 41 to the outside through the airway groove 4, so as to realize autonomous exhaust of the bonding surface in the shell.

[0049] It can be understood that the airway groove 4 between the bottom shell layer 1 and the adhesive layer 2 can be provided on the side of the bottom shell layer 1 facing the adhesive layer 2, or on the side of the adhesive layer 2 facing the bottom shell layer 1; the airway groove 4 between the adhesive layer 2 and the flexible film layer 3 can be provided on the side of the adhesive layer 2 facing the flexible film layer 3, or on the side of the flexible film layer 3 facing the adhesive layer 2. In other words, at least one of the bottom shell layer 1, the adhesive layer 2 and the flexible film layer 3 can be provided with an airway groove 4.

[0050] In some embodiments, Figure 2As shown, at least one air channel groove 4 can be provided on the adhesive layer 2, and the air channel groove 4 passes through the edge of the adhesive layer 2 to communicate with the outside. That is, the air channel groove 4 can extend to the edge of the adhesive layer 2, and the edge of the adhesive layer 2 is separated and discontinuous by the air channel groove 4. By providing the air channel groove 4 on the adhesive layer 2, the gas on the bonding surface between the adhesive layer 2 and the bottom shell layer 1, and the gas on the bonding surface between the adhesive layer 2 and the flexible film layer 3 can be discharged through the air channel groove 4.

[0051] like Figure 2 As shown, when the airway groove 4 is opened on the adhesive layer 2 , the exhaust port 41 of the airway groove 4 may at least include a port of the airway groove 4 , and the opening direction of the port is substantially parallel to the adhesive layer 2 .

[0052] It can be understood that the adhesive layer 2 is sandwiched between the bottom shell layer 1 and the flexible film layer 3. Due to the thickness of the adhesive layer 2, there may be a certain gap between the bottom shell layer 1 and the flexible film layer 3, and the gap is connected to the outside. When the airway groove 4 passes through the edge of the adhesive layer 2, the port of the airway groove 4 is open, and it can be connected to the outside through the gap between the bottom shell layer 1 and the flexible film layer 3, or the port of the airway groove 4 is substantially flush with the edges of the bottom shell layer 1 and the flexible film layer 3, so that the port of the airway groove 4 can be directly connected to the outside.

[0053] In some embodiments, the size of the adhesive layer 2 may be smaller than the size of the bottom shell layer 1, and / or, smaller than the size of the flexible film layer 3. Exemplarily, the adhesive layer 2 may be bonded to the central area of ​​the bottom shell layer 1 and the flexible film layer 3, while the edge areas of the bottom shell layer 1 and the flexible film layer 3 are separated. In other words, on a projection plane parallel to the adhesive layer 2, the orthographic projection of the adhesive layer 2 on the projection plane is located within the orthographic projection of the bottom shell layer 1 on the projection plane, and / or, the orthographic projection of the adhesive layer 2 on the projection plane is located within the orthographic projection of the flexible film layer 3 on the projection plane. In other embodiments, the size of the bottom shell layer 1, the size of the adhesive layer 2, and the size of the flexible film layer 3 may be substantially the same, so that the orthographic projection of the adhesive layer 2 on the above-mentioned projection plane completely overlaps with the orthographic projection of the bottom shell layer 1 on the projection plane, and the orthographic projection of the flexible film layer 3 on the projection plane.

[0054] In some embodiments, Figure 2 As shown, the adhesive layer 2 includes a plurality of adhesive blocks 21 arranged at intervals, and the gaps between the plurality of adhesive blocks 21 are interconnected to form an airway groove 4 .

[0055] In a specific implementation, the rubber block 21 can be directly bonded to the bottom shell layer 1 or the flexible film layer 3, so that the rubber layer 2 is hollowed out along its thickness direction. In this way, the gap between the rubber blocks 21 can cooperate with the bottom shell layer 1 or the flexible film layer 3 to form the airway groove 4, and the bottom shell layer 1 or the flexible film layer 3 can serve as the bottom wall of the airway groove 4, and the bottom wall is opposite to the notch of the airway groove 4.

[0056] In other embodiments, the adhesive layer 2 may be a 3M adhesive layer, and may further include at least one bottom adhesive layer, wherein one bottom adhesive layer may be bonded between the adhesive block 21 and the bottom shell layer 1, or bonded between the adhesive block 21 and the flexible film layer 3. In this way, the gap between the adhesive blocks 21 cooperates with one of the bottom adhesive layers to form the airway groove 4, and the bottom adhesive layer may serve as the bottom wall of the airway groove 4, and the bottom wall is opposite to the notch of the airway groove 4.

[0057] In some embodiments, the plurality of glue blocks 21 are arranged in an array, and the distance between two adjacent glue blocks 21 may be substantially the same. In addition, the size of each glue block 21 may be substantially the same.

[0058] like Figure 2 As shown, the airway groove 4 may include a plurality of first airway grooves 42 and a plurality of second airway grooves 43, wherein the first airway grooves 42 may extend in the transverse direction and the second airway grooves 43 may extend in the column direction. The first airway grooves 42 and the second airway grooves 43 intersect to separate the adhesive layer 2 into a plurality of rectangular adhesive blocks 21.

[0059] In some embodiments, Figure 3 As shown, at least one air channel groove 4 is provided on a side of the flexible film layer 3 facing the adhesive layer 2 and extends outside the adhesive layer 2 to communicate with the outside.

[0060] For example, Figure 3 As shown, on a projection plane parallel to the adhesive layer 2, the orthographic projection of the airway groove 4 provided on the flexible film layer 3 on the projection plane is partially located outside the orthographic projection of the adhesive layer 2 on the projection plane, so that the portion of the airway groove 4 not covered by the adhesive layer 2 can be used as an exhaust port 41 for exhausting the gas between the adhesive layer 2 and the flexible film layer 3. The exhaust port 41 can, for example, include a port and a part of a notch of the airway groove 4, wherein the opening direction of the port is substantially parallel to the adhesive layer 2, and the opening direction of the notch is substantially perpendicular to the adhesive layer 2.

[0061] In some embodiments, Figure 3As shown, the airway groove 4 can pass through the edge of the flexible film layer 3, so that the port of the airway groove 4 is open to communicate with the outside world. In other embodiments, there can be a certain interval between the port of the airway groove 4 and the edge of the flexible film layer 3, so that the flexible film layer 3 can close the port of the airway groove 4, and the airway groove 4 can communicate with the outside world through the partial notch exposed relative to the adhesive layer 2.

[0062] like Figure 3 As shown, the size of the adhesive layer 2 may be smaller than that of the flexible film layer 3 , so that the airway groove 4 opened at the edge of the flexible film layer 3 not covered by the adhesive layer 2 may be exposed relative to the adhesive layer 2 .

[0063] In some embodiments, Figure 4 As shown, the flexible film layer 3 may include an injection molding layer 31, an ink layer 32 and a transparent film layer 33; the injection molding layer 31 is bonded to the adhesive layer 2, and the airway groove 4 is opened on the injection molding layer 31; the ink layer 32 is located on the side of the injection molding layer 31 away from the adhesive layer 2; the transparent film layer 33 is located on the side of the ink layer 32 away from the injection molding layer 31.

[0064] In a specific implementation, the thickness of the injection molding layer 31 may be greater than the thickness of the ink layer 32, and may be greater than the thickness of the transparent film layer 33. The airway groove 4 may penetrate the injection molding layer 31 in the thickness direction, so that the depth of the airway groove 4 may be substantially equal to the thickness of the injection molding layer 31; or, the depth of the airway groove 4 may be less than the thickness of the injection molding layer 31, so that the entire side of the injection molding layer 31 close to the ink layer 32 is continuously attached to the ink layer 32, and the side of the injection molding layer 31 away from the ink layer 32 is divided by the airway groove 4 into a plurality of plastic blocks arranged in an array.

[0065] In some embodiments, Figure 5 As shown, the airway groove 4 is provided on a side of the bottom shell layer 1 facing the adhesive layer 2 and extends outside the adhesive layer 2 to communicate with the outside.

[0066] For example, Figure 5 As shown, on a projection plane parallel to the adhesive layer 2, the orthographic projection of the airway groove 4 provided on the bottom shell layer 1 on the projection plane is partially located outside the orthographic projection of the adhesive layer 2 on the projection plane, so that the portion of the airway groove 4 not covered by the adhesive layer 2 can be used as an exhaust port 41 for exhausting the gas between the adhesive layer 2 and the bottom shell layer 1. The exhaust port 41 may, for example, include a port and a portion of a notch of the airway groove 4, wherein the opening direction of the port is substantially parallel to the adhesive layer 2, and the opening direction of the notch is substantially perpendicular to the adhesive layer 2. In some embodiments, the airway groove 4 may pass through the edge of the bottom shell layer 1. In other embodiments, such as Figure 5As shown, in order to make the airway groove 4 invisible on the side of the bottom shell layer 1, there can be a certain interval between the airway groove 4 and the edge of the bottom shell layer 1, so that the bottom shell layer 1 closes the port of the airway groove 4, and the airway groove 4 can be connected to the outside through the partial notch exposed relative to the adhesive layer 2.

[0067] like Figure 5 As shown, the size of the adhesive layer 2 may be smaller than that of the bottom shell layer 1 , so that the airway groove 4 opened at the edge of the bottom shell layer 1 not covered by the adhesive layer 2 may be exposed relative to the adhesive layer 2 .

[0068] It is understandable that the above Figure 3 and Figure 5 In the figure, the airway groove 4 in the area covered by the glue layer 2 is shown by a dotted line.

[0069] In some embodiments, any two or three of the bottom shell layer 1, the adhesive layer 2 and the flexible film layer 3 may be provided with airway grooves 4, respectively, and the airway grooves 4 provided on different components may be interconnected or spaced apart. For example, the orthographic projection of the airway groove 4 provided on the adhesive layer 2 on the projection plane may at least partially overlap with the orthographic projection of the airway groove 4 provided on the bottom shell layer 1 on the projection plane; and / or, the orthographic projection of the airway groove 4 provided on the adhesive layer 2 on the projection plane may at least partially overlap with the orthographic projection of the airway groove 4 provided on the flexible film layer 3 on the projection plane, wherein the projection plane is parallel to the adhesive layer 2.

[0070] In some embodiments, Figure 2 , Figure 3 and Figure 5 As shown, the shell includes a plurality of airway grooves 4 , which intersect and communicate with each other, and the orthographic projections of the plurality of airway grooves 4 on the adhesive layer 2 separate the adhesive layer 2 into a plurality of bonding areas 22 .

[0071] The above-mentioned multiple airway grooves 4 can be opened on the same component, for example, all opened on the bottom shell layer 1; or, the above-mentioned multiple airway grooves 4 can be opened on two adjacent components, for example, respectively opened on the bottom shell layer 1 and the glue layer 2, or respectively opened on the glue layer 2 and the flexible film layer 3.

[0072] When the airway groove 4 is opened on the glue layer 2, the area where the airway groove 4 is located is not filled with the glue layer 2, which will affect the effective bonding area between the glue layer 2 and the bottom shell layer 1 and the flexible film layer 3; when the airway groove 4 is opened on the bottom shell layer 1 or the flexible film layer 3, the glue layer 2 and the bottom surface of the airway groove 4 need to be spaced from each other to allow gas to flow in the airway groove 4, so that the glue layer 2 in the area where the airway groove 4 is located is actually suspended and will not be bonded to the bottom shell layer 1 or the flexible film layer 3.

[0073] It can be seen that the adhesive layer 2 is actually only bonded to the bonding area 22 separated by the multiple airway grooves 4, and the area of ​​the bonding area 22 determines the effective bonding area of ​​the adhesive layer 2. The larger the area of ​​the bonding area 22, the better the bonding performance between the adhesive layer 2 and the bottom shell layer 1 and the flexible film layer 3, and it is less likely to delaminate; however, the larger the area of ​​the bonding area 22, the more gas may be generated on the bonding area 22, and the gas is more difficult to discharge, and the flexible film layer 3 is more likely to be lifted and deformed by the expanding gas.

[0074] It is understandable that, when the material flexibility of the flexible film layer 3 is constant, the greater the thickness of the flexible film layer 3 is, the less likely the flexible film layer 3 is to deform. Therefore, it is necessary to balance the relationship between the area of ​​the bonding area 22 and the thickness of the flexible film layer 3 .

[0075] In some embodiments, the bonding area 22 satisfies at least one of the following conditions: the area of ​​the bonding area 22 is less than or equal to 1600 times the square of the thickness of the flexible film layer 3; the area of ​​the bonding area 22 is greater than or equal to 100 times the square of the thickness of the flexible film layer 3; the maximum length of the bonding area 22 does not exceed 35mm-50mm; the maximum area of ​​the bonding area 22 does not exceed 352mm 2 -2500mm 2 .

[0076] Exemplarily, the area of ​​the bonding region 22 is less than or equal to 400 times the square of the thickness of the flexible film layer 3 , and greater than or equal to 140 times the square of the thickness of the flexible film layer 3 .

[0077] In some embodiments, the length and / or width of the bonding area 22 does not exceed 40 mm ± 2 mm. The thickness of the flexible film layer 3 is about 0.8 mm-1.2 mm, for example, 1 mm-1.2 mm; the bonding area 22 may be rectangular, with a length greater than or equal to 15 mm and a width less than or equal to 25 mm. The length or width of the bonding area 22 may be the maximum size of the bonding area in the corresponding direction (for example, the row direction or the column direction). If the size of the bonding area 22 is too large, resulting in an area that is too large, bulging is likely to occur at the bonding area 22, so it is necessary to limit the maximum size and / or maximum area of ​​the bonding area 22.

[0078] In some embodiments, Figure 6 As shown in (a)-(d) in FIG. 1 , the cross-sectional shape of the airway groove 4 is any one of a rectangle, a trapezoid, a parallelogram, or a circle. The carrier for opening the airway groove 4 can be any one of the bottom shell layer 1 , the adhesive layer 2 , and the flexible film layer 3 .

[0079] The present application also provides an electronic device, such as Figure 7As shown, the electronic device comprises the housing 100 as above, wherein the flexible film layer 3 is exposed on the surface of the electronic device.

[0080] In some embodiments, the electronic device may be, for example, a charging station or an energy storage device, which can be used to charge an electric vehicle.
