Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tablet computers, and in particular to an integral tablet computer bottom shell component and a fully laminated tablet computer. Background Art
[0002] The existing flat panel industry generally uses the INCELL full lamination process to manufacture ultra-thin displays. Because the screen and TP cover are very thin and soft, they are easily affected by assembly extrusion or deformation, resulting in screen display defects.
[0003] The traditional way of assembling the finished tablet computer is to glue the screen assembly first, then attach it to the separated face shell, and then assemble the face shell to the bottom shell assembly by snap fastening. Figure 1 as well as Figure 2 The conventional tablet computer structure shown in FIG. 1 includes a screen assembly 300, a plastic cover 200, and a bottom housing assembly 100. The plastic cover 200 includes a first buckle 201 and a second buckle 202. During assembly, the screen assembly 300 is first glued to the edges and then attached to the separated plastic cover 200. The combined screen assembly 300 and plastic cover 200 are then buckled together onto the bottom housing assembly 100. Figure 2 Shown Figure 1 A partial cross-sectional view of the existing tablet computer at position A after assembly. Figure 2 As shown, the bottom shell assembly 100 includes a limiting portion 101 and a hook 102. The first buckle 201 cooperates with the limiting portion 101 of the bottom shell assembly 100, and the second buckle 202 cooperates with the hook 102 of the bottom shell assembly 100, so that the plastic cover 200 is assembled on the bottom shell assembly 100 in a snap-fit manner.
[0004] because Figure 1 as well as Figure 2 The plastic cover of the tablet computer shown needs to be further assembled on the bottom shell assembly 100 by snap-fitting. The pulling force generated by the snap-fit again causes the TP process bonding surface of the plastic cover 200 to be concave, making it difficult to maintain coplanarity, resulting in the undesirable phenomenon of light leakage in the finished assembly of the tablet computer.
[0005] In addition, the pursuit of narrow bezels for the entire device also causes the bonding surface of the screen components to become very narrow, resulting in high bonding costs, difficult bonding, and a high defect rate. Summary of the Invention
[0006] Based on this, in order to solve the above-mentioned technical problems in traditional technologies, the utility model proposes a structure that adopts an integral frame structure to realize that the screen assembly is directly bonded to the bottom shell assembly. After assembly, the screen assembly is no longer squeezed and pulled by external forces during reassembly, which affects the display effect. The flatness of the TP process bonding surface of the bottom shell assembly can be improved, and the yield rate of the finished product assembly can be improved. The integral tablet computer bottom shell assembly and the fully bonded tablet computer are used.
[0007] In the first aspect, the utility model relates to an integral tablet computer bottom shell assembly, comprising a frame, the frame comprising a bottom wall and side walls, an installation window for assembling internal components formed on the frame, a first surface shell protruding upward from the side wall, and at least one supporting shoulder extending integrally around the inner side wall of the frame in the direction toward the center of the installation window, each supporting shoulder comprising a fitting plane, all fitting planes being coplanar, an elastic adhesive layer being provided on the fitting plane, and the screen assembly being assembled on the fitting plane through the elastic adhesive layer.
[0008] In order to avoid the RF emission angle and improve the RF quality, the side wall protrudes downward to set a second surface shell and form a bottom space. A hardware base plate is installed in the bottom space. The hardware base plate is rectangular and the adjacent corners of the hardware base plate are arc-shaped.
[0009] A buffer gap is provided between the first face shell and the screen assembly, with the buffer gap ranging from 0.1 to 0.2 mm; the elastic adhesive layer is a polyurethane sealant layer. In a second aspect, the utility model relates to a fully laminated tablet computer, comprising a bottom shell assembly and a screen assembly, wherein the screen assembly comprises an assembly periphery, the bottom shell assembly comprises a frame, the frame comprising a bottom wall and side walls, an installation window formed in the frame for assembling internal components, a first face shell protruding upwardly from the side wall, the frame integrally extending at least one support shoulder around the inner periphery of the side wall in a direction toward the center of the installation window, each support shoulder comprising a laminating plane, all laminating planes being coplanar, an elastic adhesive layer provided on the laminating plane, and the screen assembly assembled on the laminating plane via the elastic adhesive layer.
[0010] In terms of space utilization, the supporting shoulder divides the internal space of the frame into internal device assembly space and screen assembly space. The side wall of the frame protrudes downward to form a second surface shell, and the second surface shell and the bottom wall form a bottom space.
[0011] In order to cushion and prevent falls, a buffer gap is set between the outer edge of the assembly and the first surface shell, and the range of the buffer gap is 0.1 to 0.2 mm.
[0012] In order to avoid the RF emission angle and improve the RF quality, the bottom shell assembly also includes a metal base plate, which is installed in the bottom space. The metal base plate is rectangular, and the adjacent corners of the metal base plate are arc-shaped.
[0013] In order to prevent glue from overflowing, the fitting plane is arranged on the top surface of the supporting shoulder, and a glue overflow groove is opened at the junction close to the first surface shell.
[0014] In the fully laminated tablet computer, the elastic adhesive layer is a polyurethane sealant layer.
[0015] The utility model provides an integrated tablet bottom shell assembly and a fully laminated tablet computer. The self-developed elastic adhesive layer with elasticity and cushioning effect is used to ensure moderate lamination force. The elastic adhesive layer has a certain tensile toughness. In addition, since the elastic adhesive layer has good toughness and weak adhesion, and the lamination force is moderate, the elastic adhesive layer is much easier to disassemble without damaging the screen assembly and greatly reducing costs.
[0016] The integrated tablet computer bottom shell assembly and the fully laminated tablet computer of the present invention adopt an integrated frame structure and only have one bottom shell assembly, which reduces the influence of deformation and squeezing during buckling on the screen and greatly improves the screen effect of the whole machine. During assembly, the screen assembly can be directly laminated to the frame of the bottom shell assembly. After assembly, the screen assembly is no longer squeezed and pulled by the external force of the buckle assembly, which affects the display effect. This improves the flatness of the TP process bonding surface of the bottom shell assembly and improves the yield rate of the finished product assembly.
[0017] The integrated tablet bottom shell assembly and the fully laminated tablet computer of the present invention have buffer gaps between the four outer edges of the screen assembly and the stepped wall surface of the first shell of the frame. Combined with the elasticity of the elastic adhesive layer, these two aspects work together to cushion and prevent the tablet computer from falling.
[0018] In addition, the integrated tablet computer bottom shell assembly and the fully laminated tablet computer of the present invention, the bottom shell assembly also includes a metal bottom plate, the metal bottom plate is installed in the bottom space, the metal bottom plate is rectangular, the adjacent corners of the hardware bottom plate are arc-shaped, and the large C-angle design of the circumference of the hardware bottom plate can avoid the radio frequency emission angle and improve the radio frequency quality.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Please refer to Figure 3 as well as Figure 4 , which shows a fully laminated tablet computer of the present invention. The fully laminated tablet computer comprises a bottom shell component 1 and a screen assembly 5.
[0031] like Figure 3 As shown, the screen assembly 5 includes a display screen 51 and an assembly periphery 54. The circuitry of the display screen 51 is protruding from the back of the screen assembly 5. The display screen 51 provides high-resolution image display and multi-touch functionality. The screen assembly 5 of this embodiment is integrally assembled to the bottom housing assembly 1 using a TP process and is used to display information, such as images, videos, and user interfaces, to the user.
[0032] The frame 11 of the bottom housing assembly 1 is designed as an integrated frame structure, comprising the frame 11 and a metal base plate 12 mounted at the bottom of the frame 11. The frame 11 demarcates the installation space for the screen assembly and internal circuit components. The interior of the frame 11 is used to mount components such as the tablet's motherboard and memory. The top of the frame 11 is used to assemble the screen assembly 5, with the circuitry on the back of the screen assembly 5 recessed into the frame 11 through a mounting window 112 at the front of the frame 11.
[0033] like Figure 6 As shown, the frame 11 includes a bottom wall 110 and side walls 111. A mounting window 112 is formed in the frame 11 for assembling internal components. The side walls 111 further protrude upward and extend outward to form a first surface shell 115. The frame 11 is integrally provided with at least one supporting shoulder 113 extending around the inner periphery of the side walls 111 toward the center of the mounting window 112. Each supporting shoulder 113 includes a mating surface 1130, and all mating surfaces are coplanar.
[0034] The inner wall of the first shell 115 is perpendicular to the inner surface of the fitting plane 1130 of each supporting shoulder 113 and presents an inner stepped shape.
[0035] An elastic adhesive layer 6 is provided on the fitting plane 1130. The screen assembly 5 is assembled on the fitting plane 1130 through the elastic adhesive layer 6, and the outer edge 54 of the assembly is flush with or slightly lower than the first surface shell 115. The fully fitted tablet computer of this embodiment adopts an integral frame structure. By providing the elastic adhesive layer 6, a buffering effect is provided between the screen assembly 5 and the bottom shell component 1 and the cost is reduced. By adopting an integral structure of the frame 11, the screen assembly 5 can be directly attached to the frame 11 of the bottom shell component. After assembly, the screen assembly 5 is no longer squeezed and pulled by the external force of the snap assembly to affect the display effect, thereby improving the flatness of the TP process fitting surface of the bottom shell component and improving the yield rate of the finished product assembly.
[0036] Please refer to Figure 6 、 Figure 7 as well as Figure 8 In order to achieve complete fit of the entire product after assembly, the thickness of the assembly outer edge 54 of the screen assembly 5 is the same as or slightly lower than the step height H of the first surface shell 115.
[0037] like Figure 6 As shown, a buffer gap D is set between the assembly outer edge 54 and the first surface shell 115, and the buffer gap D ranges from 0.1 to 0.2 mm, including the end value, to ensure that it plays a buffering and anti-fall role when falling.
[0038] like Figure 6 as well as Figure 8As shown, the fitting plane 1130 is set on the top surface of the supporting shoulder 113, and a glue overflow groove 114 is opened near the junction of the first surface shell 115 to prevent glue from overflowing when the screen assembly 5 and the frame 11 are assembled.
[0039] The support shoulder 113 divides the interior space of the frame 11 into an internal component assembly space R2 and a screen assembly space R1. A second housing 116, also known as a bottom housing, protrudes downward from the sidewall 111 of the frame 11. This second housing 116 and the bottom wall 111 form a bottom space, thereby optimizing space utilization within the monolithic structure of the frame 11.
[0040] The bottom shell assembly 1 also includes a metal base plate 12. The bottom space is provided with the metal base plate 12. The metal base plate 12 is rectangular, and the adjacent corners of the metal base plate are curved to avoid the RF transmission angle and improve the RF quality.
[0041] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
