Description

Technical Field

[0001] This utility model relates to the technical field of flat plate protective shells, and in particular to a flat plate protective shell with a double-layer edge protection structure. Background Technology

[0002] As tablet computers become increasingly popular in daily life, they are now often equipped with protective cases to ensure their safety and protection during use. However, most tablet cases on the market are made of a single material and have a relatively simple protective structure. When a tablet is subjected to collisions or drops, it is difficult to effectively cushion the external force to protect the device. Furthermore, most tablet cases have limited functionality and lack ease of use. Therefore, how to design a tablet case with excellent protective performance and ease of use is a technical problem that enterprise technical personnel urgently need to solve. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides a flat panel protective shell with a double-layer edge protection structure.

[0004] The above-mentioned inventive objective of this application is achieved through the following technical solutions: A tablet protective case with a double-layer edge protection structure includes a back panel and an edge shell. The edge shell is hollow. The back panel is connected to the edge shell and forms a mounting groove for placing the tablet computer. The back panel is used to fit the back of the tablet computer. The edge shell includes an inner ring layer and an outer ring layer. Several reinforcing ribs are fixedly connected between the inner ring layer and the outer ring layer. The inner ring layer is used to fit the edge of the tablet computer. The back panel is made of a rigid material, and the edge shell is made of an elastic material.

[0005] Preferably, the inner ring layer has a sleeve groove along its circumference on the inner sidewall, and the sleeve groove is sleeved and fitted with the back plate.

[0006] Preferably, the edge shell further includes a connecting surface layer, which is fixedly connected between the inner ring layer and the outer ring layer and located on the side of the inner ring layer and the outer ring layer near the back plate.

[0007] Preferably, a stylus groove is provided between the inner ring layer, the outer ring layer, and the connecting surface layer, and a pen-pushing hole is provided in the stylus groove.

[0008] Preferably, the cross-section of the outer ring layer is concave.

[0009] Preferably, two symmetrically arranged hanging holes are provided between the inner ring layer and the outer ring layer.

[0010] Preferably, the flat protective shell with a double-layer edge protection structure further includes a face cover, which is disposed on one side of the outer ring layer and is used to fold towards the mounting groove. The face cover has a plurality of connection holes in the vertical direction. An inner clamping groove is formed on one side of the outer ring layer in the vertical direction. A first mounting plate and a second mounting plate are disposed opposite each other in the inner clamping groove. A plurality of connecting posts are provided on the first mounting plate corresponding to the position and number of the connection holes. A plurality of connecting grooves are formed on the second mounting plate corresponding to the number and position of the connecting posts. The connecting grooves are inserted into the corresponding connecting posts. The connection holes are used for the connecting posts to pass through.

[0011] Preferably, the rigid material is any one of PC, PET, ABS or PMMA.

[0012] Preferably, the elastic material is any one of TPU, rubber, or silicone.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This application utilizes a rigid material backplate that adheres to the back of the tablet computer to provide structural support and back protection. The high hardness of the rigid material protects the back of the tablet computer from damage caused by impacts. The elastic material edge shell consists of an inner ring layer, an outer ring layer, and several reinforcing ribs to form a hollow double-layer buffer structure. By utilizing the buffering performance of the elastic material and the structural strength of the reinforcing ribs, the external force during collisions and drops can be dispersed, improving drop protection performance. Furthermore, by placing the backplate in the socket of the inner ring layer, i.e., the backplate is located in the hollow part of the edge shell, it facilitates the installation and removal of the backplate. In the event of an accidental drop of the tablet computer, the elastic material edge shell will make priority contact with the ground, preventing the rigid backplate from directly colliding with the ground and breaking. This further reduces the risk of damage to the tablet computer due to impacts on the back. Meanwhile, the stylus slots surrounding the inner ring layer, outer ring layer, and connecting surface layer provide a dedicated storage location for the stylus. Combined with the stylus push hole, the stylus can be quickly retrieved, improving the tablet's ease of use. The concave cross-section design of the outer ring layer optimizes the grip feel of the edge shell and prevents accidental button presses when the tablet case is placed on its side. Symmetrically arranged lanyard holes allow for the attachment of shoulder straps or other straps, providing a convenient way to carry the tablet. Furthermore, the foldable and removable cover can cover the screen for protection when the tablet is not in use. The cover is stably connected to the outer ring layer via connecting holes, connecting posts, and connecting slots, making installation and removal easy and preventing the cover from falling off, further enhancing the tablet case's usability. Overall, this application solves the problem of insufficient protection from a single material in existing tablet cases by combining a rigid backplate and a flexible double-layer edge shell with functions such as stylus storage, lanyard compatibility, and screen protection. It also makes up for the problems of limited functionality and poor ease of use, thus achieving a joint improvement in both the protective performance and user experience of tablet cases.

[0019] The following is a reference appendix. Figure 1 To be continued Figure 4 This application describes a flat protective shell with a double-layer edge protection structure.

[0020] like Figure 1 As shown, the tablet protective shell with a double-layer edge protection structure includes a back plate 1 and an edge shell 2. The edge shell 2 is hollow. The back plate 1 is connected to the edge shell 2 and forms a mounting groove 3 for placing the tablet computer. The back plate 1 is used to fit the back of the tablet computer. The edge shell 2 includes an inner ring layer 21 and an outer ring layer 22. Several reinforcing ribs 23 are fixedly connected between the inner ring layer 21 and the outer ring layer 22. The inner ring layer 21 is used to fit the edge of the tablet computer. The back plate 1 is made of a rigid material, and the edge shell 2 is made of an elastic material. Specifically, when the tablet computer is placed in the mounting slot 3, the back plate 1 made of rigid material provides structural support and back protection for the back of the tablet computer. The inner ring layer 21 made of elastic material fits the edge of the tablet computer to achieve circumferential protection. At the same time, the inner ring layer 21, outer ring layer 22 and reinforcing rib 23 of the edge shell 2 form a hollow double-layer buffer structure. Combining the buffer performance of the elastic material and the structural strength of the reinforcing rib 23, it can effectively disperse the external force during collision and drop, improve the overall protection performance, and thus solve the problem of insufficient protection of the single material of the existing tablet protective shell. It should be noted that both the inner ring layer 21 and the outer ring layer 22 are provided with functional holes such as USB plugs and speaker holes to accommodate the daily charging, connection and use of the tablet computer. The specific location and number of these functional holes are common knowledge to those skilled in the art and will not be described in detail here.

[0021] As a preferred option, such as Figure 2 and Figure 3 As shown, the inner ring layer 21 has a sleeve groove 4 along its circumference on its inner sidewall. The sleeve groove 4 is sleeved with the back plate 1. By setting the sleeve groove 4 in the inner ring layer 21 and sleeved with the back plate 1, a stable connection between the back plate 1 and the edge shell 2 can be achieved. At the same time, the elasticity of the edge shell 2 and the sleeve structure can facilitate the disassembly and replacement of the back plate 1, improving the maintenance convenience of the tablet protective case. Furthermore, by setting the back plate 1 in the sleeve groove 4 of the inner ring layer 21, that is, the back plate 1 is located in the hollow part of the edge shell 2, it is not only convenient to disassemble and install the back plate 1, but also ensures that the elastic material edge shell 2 will first contact the ground when the tablet is accidentally dropped, avoiding direct collision between the hard back plate 1 and the ground and thus preventing damage. This further reduces the risk of the tablet being damaged by the impact of the back.

[0022] Preferably, the edge shell 2 further includes a connecting surface layer 24, which is fixedly connected between the inner ring layer 21 and the outer ring layer 22 and located on the side of the inner ring layer 21 and the outer ring layer 22 near the back plate 1. By providing the connecting surface layer 24, the structural integrity of the edge shell 2 can be enhanced, the relative deformation of the inner ring layer 21 and the outer ring layer 22 can be avoided, and the structural strength of the flat protective shell can be improved. It should be noted that the inner ring layer 21, the outer ring layer 22 and the connecting surface layer 24 can be fixedly connected by integral manufacturing, which can be achieved by injection molding process, significantly improving the overall structural stability and deformation resistance of the edge shell 2, ensuring the long-term use of the flat plate protective shell, and is suitable for the working conditions of the flat plate protective shell.

[0023] Furthermore, such as Figure 1 As shown, a stylus slot 5 is provided between the inner ring layer 21, the outer ring layer 22 and the connecting surface layer 24. A stylus push hole 6 is provided in the stylus slot 5. By setting the stylus slot 5 and cooperating with the stylus push hole 6, the stylus can be specially stored, solving the problem of lacking a stylus storage structure and improving the ease of use of the tablet computer.

[0024] As a preferred option, such as Figure 1 and Figure 4 As shown, the outer ring layer 22 has a concave cross-section, which can adapt to the curvature of the user's fingers, improve the grip of the protective case, prevent slippage during use, enhance the comfort of using the tablet protective case, and prevent accidental button presses when the tablet protective case is placed on the side, thereby improving the ease of use of the tablet.

[0025] As a preferred option, such as Figure 1 As shown, two symmetrically arranged lanyard holes 7 are provided between the inner ring layer 21 and the outer ring layer 22, which can be threaded through the shoulder strap or other straps, providing a convenient way to carry the tablet computer and improving the product's convenience and flexibility of use.

[0026] As a preferred option, such as Figure 3 and Figure 4As shown, the flat protective shell with a double-layer edge protection structure also includes a face cover 8, which is disposed on one side of the outer ring layer 22 and is used to fold towards the mounting groove 3. The face cover 8 has several connecting holes (not shown in the figure) in the vertical direction. An inner clamping groove 9 is formed on one side of the outer ring layer 22 in the vertical direction. A first mounting plate 10 and a second mounting plate 11 are arranged opposite each other in the inner clamping groove 9. Several connecting posts 12 are arranged on the first mounting plate 10 corresponding to the position and number of the connecting holes. Several connecting posts 12 are arranged on the second mounting plate 11 corresponding to the number and position of the connecting posts 12. The connecting groove 13 is connected to the corresponding connecting post 12. The connecting hole is used for the connecting post 12 to pass through. The flip-out cover 8 can cover the screen to protect the screen when the tablet is not in use. The cover 8 is stably connected to the outer ring layer 22 through the connecting hole, the connecting post 12 and the connecting groove 13, which prevents the cover 8 from falling off. At the same time, the elasticity of the outer ring layer 22 makes it easy to install and remove the connecting post 12 and the connecting groove 13, which further improves the ease of use of the tablet protective case.

[0027] Preferably, the rigid material is any one of PC, PET, ABS, or PMMA. All of these materials can meet the protection requirements for the back of the tablet computer in terms of hardness and strength. Technicians can choose the appropriate material according to different usage requirements, such as strength, light transmittance, and cost. In this embodiment, PC is preferred. PC material has excellent impact toughness. Even if the back of the tablet computer is hit by hard objects such as the edge of a table or a key, it can effectively resist external forces and avoid problems such as the back panel 1 breaking or the tablet back shell denting. At the same time, PC material has excellent light transmittance, which can clearly show the brand logo and texture design on the back of the tablet computer, taking into account both protection and visual aesthetics, and is suitable for the working conditions of tablet protective cases.

[0028] Preferably, the elastic material is any one of TPU, rubber, or silicone. These materials can meet the protection requirements for the back of a tablet computer in terms of both elasticity and strength. Technicians can select the appropriate material according to different usage needs, such as temperature resistance and hand comfort. In this embodiment, TPU is preferred. TPU material has both excellent elasticity and structural strength. It can quickly rebound and reset after being squeezed or bumped by external force, which can effectively disperse the impact force received by the edges of the tablet computer when it is dropped. At the same time, TPU has strong temperature resistance. It is not easy to soften and stick when placed in high temperature in summer, and it is not easy to harden and crack in low temperature environment in winter. It is suitable for various daily use scenarios. In addition, the surface of TPU material is smooth to the touch, which can improve the comfort of holding, making it suitable for tablet protective cases.

[0029] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
