Description

Technical Field

[0001] The utility model relates to the field of tablet accessories, and specifically to a drop-proof tablet stand protective case. Background Art

[0002] With the popularization of electronic devices such as tablets, users may often use tablet devices under various environmental conditions, including at home, in the office, or during outdoor travel. However, since the outer shell of the tablet device is relatively thin and fragile, accidental impacts, drops, and other physical shocks may cause damage to the tablet device. Especially when the edge of the tablet collides with other objects, the stress is more concentrated due to the small contact area of the collision, so it is more likely to be damaged. Currently, the tablet protective cases on the market include single-layer protective cases made of silicone or plastic. However, due to the limited anti-drop performance of these single-layer protective cases, they cannot effectively absorb and disperse the impact force, and the tablet device will still be damaged under a large impact force. In addition, the existing tablet stands have complex structures, inconvenient adjustment, unstable use, and cannot meet the user's need for multi-angle support of the tablet.

[0003] How to design a tablet protective case that can still provide comprehensive protection for the tablet in the face of a large impact, and a tablet stand that meets the user's requirement for multi-angle stable support of the tablet is a technical problem that manufacturers urgently need to solve. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drop-proof tablet stand protective case. The tablet stand protective case includes an inner frame and an outer shell. A plurality of reinforcing rib strips protruding towards the inside of the shell are formed on the inner wall of the wrapping edge of the outer shell, and the outer wall of the wrapping edge of the inner frame is covered with airbag grooves of various sizes. The outer edges of each reinforcing rib strip and the outer wall of the wrapping edge of the inner frame are adhesively connected by hot pressing. At this time, an annular airbag layer that encloses and wraps all the airbag grooves is formed. When the tablet accidentally falls from a height or is subjected to an accidental impact, the annular airbag layer can serve as a buffer layer to effectively absorb and disperse the large impact force generated by the collision, avoiding the tablet from being damaged by the impact. The appearance of the reinforcing ribs increases the overall thickness of the side wall of the wrapping edge of the tablet protective case. While effectively resisting the impact, it can also ensure the stable connection between the outer shell and the inner frame and is not easily damaged. Moreover, a strip-shaped stand is provided on the back of the tablet protective case, and the strip-shaped stand can be flipped relative to the shell at an angle of 0 to 135 degrees. Through this special strip-shaped stand structure combined with a specific flipping angle, the stand can support multi-angle horizontal and vertical standing supports. In addition, a hanging rope hole is provided on the protective case, and the tablet can be hung around the neck or on the wrist through the hanging rope, which is easy and labor-saving to carry.

[0035] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments and descriptions thereof of the present utility model are only used to explain the present utility model and shall not be construed as limiting the present utility model.

[0036] The present utility model will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0037] According to an embodiment of the present utility model, as Figures 1 to 5 , a drop-proof tablet stand protective case includes:

[0038] a housing 1, an inner frame 2, a support bar and a limiting plate 5;

[0039] The housing 1 is an integral structure of a bottom plate and four wrapping edges. The inner frame 2 is a frame structure of four wrapping edges. A receiving groove for receiving the support bar is formed on the back surface of the housing 1;

[0040] Reinforcing ribs protruding towards the inside of the housing are provided on the inner wall of the wrapping edge of the housing 1. A number of concave airbag grooves are uniformly and densely distributed on the outer wall of the wrapping edge of the inner frame 2;

[0041] The reinforcing ribs and the outer wall edge of the wrapping edge of the inner frame 2 are bonded to form an annular airbag layer that completely encloses and wraps the entire airbag groove;

[0042] The support bar includes a fixed support bar 3 and a flipping support bar 4. The fixed support bar 3 is fixed in the receiving groove, and the flipping support bar 4 is hinged to the fixed support bar 3;

[0043] The limiting plate 5 is fixedly connected to the hinged part of the flipping support bar 4 and the fixed support bar 3 for restricting the flipping of the flipping support bar 4 relative to the housing 1 by an angle of 0 to 135 degrees.

[0044] Most of the tablet protective cases on the market at present are single-layer protective cases formed by one-piece thermocompression molding of silicone or plastic materials. However, due to the limited drop-proof performance of these single-layer protective cases, they cannot effectively absorb and disperse the impact force, and the tablet device will still be damaged under the action of a large impact force; moreover, a large number of collision experiments show that when the edge of the tablet collides with the surface of the tablet, the edge of the tablet is more likely to be damaged by the collision; the reason is that the edge of the tablet usually has a smaller area compared to the body of the tablet. When the collision force acts on the tablet, it will cause stress concentration at the edge of the tablet, making the edge of the tablet bear greater stress. Stress concentration is likely to cause the rupture and damage of the material.

[0045] Therefore, based on years of work experience, the inventors of the present application designed a drop-proof tablet protective case with an airbag layer included in a double-layer wrapping edge, which provides more comprehensive protection for the tablet when it is subjected to a collision impact with a large stress, preventing it from being damaged by the collision. The tablet protective case in this embodiment includes a housing 1 and an inner frame 2 made of TPU material. There are multiple reinforcing rib strips protruding towards the inside of the housing on the inner wall of the wrapping edge of the housing 1, and there are several airbag grooves on the outer wall of the wrapping edge of the inner frame 2. The upper and lower edges of the outer wall of the wrapping edge of the inner frame 2 and the multiple reinforcing ribs of the wrapping edge of the housing 1 are bonded by hot pressing, forming an annular airbag layer that completely encloses and wraps all the airbag grooves. When the edge of the tablet collides with the collision surface, this annular airbag layer serves as a buffer layer, absorbing and dispersing the impact force generated by the collision through deformation, protecting the tablet from being damaged by the collision. Furthermore, the reinforcing rib strips protruding towards the inside of the housing increase the bonding surface with the inner frame 2, which can ensure the stable connection between the housing 1 and the inner frame 2, thus ensuring the stability of the entire device. At the same time, the reinforcing rib strips further thicken the thickness of the wrapping edge through bonding with the inner frame 2, thereby providing stronger protection against the collision impact of the tablet. In addition, the inventors of the present application also designed a strip-shaped tablet stand on the back of the housing 1. The strip-shaped tablet stand includes a fixed support strip 3 and a flipping support strip 4. The fixed support strip 3 is fixed in the receiving groove on the back of the housing 1, and the flipping support strip 4 is hinged to the fixed support strip 3. The flipping angle of the flipping support strip 4 on the back of the housing is limited to 0 to 135 degrees by a limit plate 5. Through this special strip-shaped support structure combined with a specific flipping angle, this support can support multi-angle horizontal and vertical screen standing, facilitating users to use the tablet with their hands free.

[0046] Furthermore, the upper corners and lower corners of the wrapping edge of the inner frame 2 protrude inward, forming a pen slot 6 for placing a tablet electronic pen.

[0047] In this embodiment, the tablet electronic pen is one of the important accessories of the tablet computer and needs to be frequently taken during use. The inventors of the present application designed a special pen slot 6 in the tablet protective case, which can conveniently fix the tablet electronic pen on the tablet protective case for use at any time, not easy to lose, improving the portability and usability of the tablet.

[0048] Furthermore, the fixed support strip 3 is bonded to the receiving groove by a support rubber strip 7, and the flipping support strip 4 is hinged to the fixed support strip 3 through a hinge 8.

[0049] In this embodiment, the fixed support bar 3 is adhered to the accommodation groove on the back of the outer shell 1 through the support rubber strip 7. This fixing method can ensure that the flat support bar is firmly fixed on the back of the flat protective case and is not easily detached. The flipping support bar 4 can be flipped on the back of the flat protective case through the hinge 8 and the articulation with the fixed support bar 3, enabling the user to select different angles to support the flat panel and meet the viewing and operation requirements of the flat panel in different scenarios.

[0050] Furthermore, the hinge 8 includes a first fixing piece, a second fixing piece, and a hinge shaft.

[0051] A riveting hole is provided on the fixed support bar 3, and a rivet riveted to the riveting hole is further provided on the limiting plate 5. The limiting plate 5 communicates with the first fixing piece and is riveted to the fixed support bar 3.

[0052] The flipping support bar 4 is riveted to the second fixing piece, and the flipping support bar 4 is enabled to perform a flipping activity on the back of the outer shell 1 through the hinge shaft of the first fixing piece and the second fixing piece.

[0053] In this embodiment, the limiting plate 5 is riveted to the fixed support bar 8 through the hinge 8, so that the limiting plate 5 is firmly connected to the flat support bar, and is used to limit that when the flipping support bar 4 is flipped to 135 degrees, it cannot be flipped further, preventing the flipping support bar 4 from becoming unstable and colliding due to excessive flipping angle.

[0054] Furthermore, the flat support protective case is also provided with a lanyard hole 9 penetrating the bottom plate of the outer shell 1.

[0055] In this embodiment, the lanyard hole 9 enables the user to conveniently use a lanyard to hang the flat panel on the wall or other supports, enabling the user to properly store the flat panel when not in use and reducing accidental risks such as falling or scratching. In addition, the lanyard hole 9 also enables the user to hang and carry the flat panel with a rope, improving its portability.

[0056] Furthermore, a buckling groove for buckling the flipping support bar 4 to the fixed support bar 3 is reserved on the flipping support bar 4.

[0057] In this embodiment, the buckling groove can firmly buckle the flipping support bar 4 to the fixed support bar 3 to ensure that the bar-shaped support will not accidentally loosen or detach during use. At the same time, the design of the buckling groove can make the flipping support bar 3 present a consistent and coherent appearance when buckled to the fixed support bar 4, and this consistent appearance helps to enhance the overall aesthetic feeling of the product and improve the user experience.

[0058] Furthermore, anti-slip patterns are provided on the outer wall of the wrapping edge of the outer shell 1 and the supporting end of the flipping support bar 4.

[0059] In this embodiment, the anti-slip pattern design can increase the friction between the outer shell 1 and the supporting end of the flipping bracket strip 4, thereby providing better grip, preventing the tablet from sliding or shaking during use, and thus maintaining stable support for the tablet. At the same time, the design of the anti-slip pattern can improve the holding comfort of the hand, making it easier for the user to grasp and control the tablet and reducing the risk of accidental dropping.

[0060] Furthermore, finger grooves for flipping and opening / closing are also provided on the flipping bracket strip 4.

[0061] In this embodiment, by providing finger grooves on the flipping bracket strip 4, when the user needs to use the flipping bracket 4 to support the tablet, the user can lift it up through the finger grooves, which is more convenient and labor-saving.

[0062] Furthermore, the tablet bracket protective case is also provided with microphone holes and speaker holes that penetrate through the outer shell 1 and the inner frame 2.

[0063] In this embodiment, the design of providing microphone holes and speaker holes can improve the audio transmission quality when the tablet is nested in the tablet case.

[0064] Furthermore, the tablet bracket protective case is also provided with a charging hole that penetrates through the outer shell 1 and the inner frame 2.

[0065] In this embodiment, the design of the charging hole enables the user to conveniently and quickly insert the charger into the tablet for charging, enhancing the convenience of use.

[0066] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above description is only the specific embodiments of the present utility model and is not used to limit the protection scope of the present utility model.
