Description

Technical Field

[0001] This utility model relates to the field of electronic product accessories technology, specifically a protective case structure for a screen-protecting commercial tablet. Background Technology

[0002] The primary function of a commercial tablet case is to protect the tablet from physical damage during daily use, such as scratches, bumps, and drops. Since tablets are carried around, the screen is easily scratched, which can shorten the overall lifespan of the tablet.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent No. CN202548726U, published on 2012-12-21) provides a tablet computer protective case, comprising a rear protective plate located at the center of the rear side of the tablet computer, and an annular sleeve connected to the rear protective plate around its perimeter. The annular sleeve is an integral flexible sheet-like body with a central cavity and four surrounding edges around the central cavity, the central cavity corresponding to the tablet computer's touchscreen. The four surrounding edges of the annular sleeve bypass the four edges of the tablet computer and connect to the rear protective plate. The surrounding part has good flexibility, enabling a tight fit with the tablet computer and good aesthetics. Chamfered and notched structures are used in the transition areas of the four surrounding edges, and a rigid rear protective plate is used on the rear side. The entire protective case is connected by only one stitched section, which is not only simple in structure and easy to process, but also results in a flat structure with good strength after processing. One of the surrounding edges is detachable, allowing for easy insertion and removal of the tablet computer.

[0004] The aforementioned methods protect the tablet by wrapping it with an outer layer. However, in actual use, when the tablet is dropped and the screen is directly impacted, the screen is prone to damage, which in turn shortens the overall lifespan of the screen. Utility Model Content

[0005] The purpose of this utility model is to provide a protective case structure for a screen-protecting commercial tablet, in order to solve the problem mentioned in the background art that when the tablet is dropped, the screen is easily damaged when it is directly in the impact point, which leads to a shortened service life of the entire screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective case structure for a screen-protecting commercial tablet, comprising a protective case body, a charging interface hole on the left side of the protective case body, a sound hole at the front end of the left side of the protective case body, a camera through hole on the right side of the bottom end of the protective case body, an airbag layer on the outer side of the protective case body, a reinforced layer on the top end of the protective case body, and a protective mechanism for protecting the screen on the top end of the protective case body, the protective mechanism including an elastic airbag, the elastic airbag being disposed at the upper end of the inner side of the protective case body, the top end of the elastic airbag being connected to an elastic hollow layer through a connecting tube, the elastic hollow layer being disposed at the top end of the protective case body, a fixing layer being disposed on the left side of the bottom end of the inner side of the protective case body, and a support mechanism for supporting the whole being being disposed at the bottom end of the protective case body.

[0007] Furthermore, the connecting tube is disposed inside the heightened layer, and the bottom end of the connecting tube is connected to the top end of the elastic airbag, while the top end of the connecting tube is connected to the bottom end of the elastic hollow layer.

[0008] Furthermore, wear-resistant protrusions are evenly distributed at the top of the elastic hollow layer, and the cross-section of the wear-resistant protrusions is semi-circular. The wear-resistant protrusions are located above the protective sleeve body.

[0009] Furthermore, the support mechanism includes a rotating layer, which is rotatably connected to the bottom end of the fixed layer. The rotating layer is located below the protective sleeve body. A support bar is installed on the left side of the bottom end of the rotating layer via a connecting block, and a fixed block is provided on the right side of the bottom end of the rotating layer. A fixing groove matching the fixing block is provided on the right side of the support bar.

[0010] Furthermore, a groove is provided at the bottom of the protective sleeve body, and a slider matching the groove is provided on the right side of the rotating layer. The groove is semi-circular.

[0011] Furthermore, the bottom end of the protective sleeve body is rotatably connected to a limit block, and a positioning block is provided on the left side of the bottom end of the limit block. The bottom end of the slider is provided with a positioning groove that matches the positioning block.

[0012] Furthermore, the limiting block is positioned above the slide groove, and the bottom end of the positioning block extends into the interior of the positioning groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By adding a raised layer at the top edge of the protective case, the edge of the protective case is higher than the screen height of the internal tablet. This allows the raised layer at the edge of the protective case to prevent dust and gravel from impacting the tablet surface when it is hit face down.

[0015] Furthermore, when the tablet is placed inside the protective case, the edges of the tablet will compress the elastic airbag, causing the gas inside the elastic airbag to be transported through the connecting tube to the interior of the elastic hollow layer. The elastic hollow layer increases the height of the extended layer, thus effectively preventing the screen from directly contacting the ground when the tablet is dropped.

[0016] Furthermore, to prevent the elastic hollow layer from being damaged by friction during use, wear-resistant bumps can protect the surface of the elastic hollow layer, preventing damage and allowing the elastic airbag and the elastic hollow layer to work together to better protect the flat plate.

[0017] 2. By pulling the support bar to one side, the support bar can drive the fixing groove to slide on the outside of the fixing block. When the left side of the fixing groove is in contact with the left side of the fixing block, the support bar forms a semi-circular shape. The thickness and strength of the support bar itself, as well as the shape of the support bar after being pulled, can support the plate placed inside.

[0018] Furthermore, when the rotating layer rotates, the slider is driven and slides inside the groove, making the overall rotation and sliding of the rotating layer smoother. When the rotating layer is adjusted to a horizontal or vertical state, the positioning block on one side of the limiting block engages with the positioning groove, thereby restricting and fixing the horizontal or vertical state of the rotating layer. This makes the support bar more stable when supporting the tablet horizontally or vertically, and avoids the support angle from deflecting during support. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the issue of screen damage and shortened lifespan when a tablet is dropped and the screen is directly impacted. The protective case structure for this commercial tablet discloses a protective mechanism including a protective case body 1. The left side of the protective case body 1 has a charging port 2, and the front left side of the protective case body 1 has a sound hole 3. The right side of the bottom of the protective case body 1 has a camera through-hole 4. An airbag layer 5 is provided on the outer side of the protective case body 1, and a reinforced layer 6 is provided at the top of the protective case body 1. The top of the protective case body 1 also has a feature for protecting the screen. The protective mechanism includes an elastic airbag 7, which is located at the upper end of the inner side of the protective sleeve body 1. The top of the elastic airbag 7 is connected to the elastic hollow layer 9 via a connecting tube 8. The elastic hollow layer 9 is located at the top of the protective sleeve body 1. The connecting tube 8 is located inside the reinforced layer 6, and the bottom end of the connecting tube 8 is connected to the top of the elastic airbag 7. The top end of the connecting tube 8 is connected to the bottom end of the elastic hollow layer 9. Wear-resistant protrusions 10 are evenly distributed at the top of the elastic hollow layer 9, and the cross-section of the wear-resistant protrusions 10 is semi-circular. The wear-resistant protrusions 10 are located above the protective sleeve body 1.

[0029] In this example, the tablet to be protected is placed inside the protective case body 1. The raised layer 6 at the top edge of the protective case body 1 ensures that the edge of the protective case body 1 is higher than the screen height of the tablet inside. This prevents dust and debris from impacting the tablet's surface when it is dropped face-down. When the tablet is inside the protective case body 1, the edge of the tablet compresses the elastic airbag 7, causing the gas inside the airbag 7 to be transported through the connecting tube 8 to the interior of the elastic hollow layer 9. The elastic hollow layer 9 increases the height of the raised layer 6, effectively preventing the screen from directly contacting the ground when the tablet is dropped. To prevent the elastic hollow layer 9 from being damaged by friction during use, wear-resistant bumps 10 protect the surface of the elastic hollow layer 9, preventing damage. Thus, the elastic airbag 7 and the elastic hollow layer 9 work together to better protect the tablet.

[0030] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 6 The technical solution shown addresses the problem of inconvenient tilting and support for tablets during use. The protective case structure for this screen-protecting commercial tablet discloses a support mechanism. A fixing layer 11 is located on the left side of the bottom of the protective case body 1, and a support mechanism for supporting the entire structure is located at the bottom of the protective case body 1. The support mechanism includes a rotating layer 12, which is rotatably connected to the bottom of the fixing layer 11. The rotating layer 12 is positioned below the protective case body 1. A support strip 14 is installed on the left side of the bottom of the rotating layer 12 via a connecting block, and a fixing block 13 is located on the right side of the bottom of the rotating layer 12. A fixing groove 15 matching the fixing block 13 is opened on the right side of the support strip 14. A sliding groove 19 is opened at the bottom of the protective case body 1, and a slider 16 matching the sliding groove 19 is located on the right side of the rotating layer 12. The sliding groove 19 is semi-circular.

[0031] In this example, to ensure the tablet can be supported by a protective cover during use and to guarantee a better viewing angle, the support strip 14 is pulled to one side, allowing the fixing groove 15 to slide outside the fixing block 13. When the left side of the fixing groove 15 is in contact with the left side of the fixing block 13, the support strip 14 forms a semi-circular shape. The thickness and strength of the support strip 14, as well as its shape after being pulled, support the tablet placed inside. Since the tablet can be used horizontally or vertically, to ensure the support mechanism can be adjusted according to different usage orientations, a rotating connection between the rotating layer 12 and the fixing layer 11 is used. This allows the rotating layer 12 to rotate and adjust the angle of the support strip 14, thus providing stable support according to usage requirements and increasing its applicability. Furthermore, when in use, the curved support strip 14 allows the palm to pass through and hold the entire tablet, increasing stability when holding and displaying the tablet and preventing it from slipping from the hand.

[0032] Example 3: Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The technical solution shown addresses the issue of potential angular displacement of the support mechanism when the tablet is supported by it. The protective case structure of this screen-protecting commercial tablet discloses a limiting mechanism. The bottom of the protective case body 1 is rotatably connected to a limiting block 18, and a positioning block 20 is provided on the left side of the bottom of the limiting block 18. The bottom of the slider 16 has a positioning groove 17 that matches the positioning block 20. The limiting block 18 is positioned above the sliding groove 19, and the bottom of the positioning block 20 extends into the interior of the positioning groove 17.

[0033] In this example, when the rotating layer 12 rotates to adjust the angle of the support mechanism, in order to ensure the stability of the rotating layer 12 during support, the slider 16 is driven and slides inside the slide groove 19 when the rotating layer 12 rotates, so that the overall rotation and sliding of the rotating layer 12 can be smoother. When the rotating layer 12 is adjusted to a horizontal or vertical state, the positioning block 20 on one side of the limiting block 18 and the positioning groove 17 are engaged with each other, so that the horizontal or vertical state of the rotating layer 12 can be restricted and fixed, so that the support bar 14 can be more stable when supporting the tablet horizontally or vertically, and avoid the situation of support angle deviation during support.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
