Description

Technical Field

[0001] This utility model relates to the technical field of electronic device accessories, and in particular to a tablet leather case keyboard. Background Technology

[0002] With the widespread use of tablets in work, study, and entertainment, tablet keyboard cases, as an important accessory that combines protection and input functions, have attracted much attention for their user experience.

[0003] In daily use, traditional connection methods present numerous problems when users close the tablet case / keyboard cover for storage or transport. For example, some cases use a snap-on connection, which is cumbersome and prone to damage. Others use magnetic locking lugs, where the lugs connect to one edge of the cover and keyboard, and the case magnetically attaches to the other surface after closing. However, this method lacks auxiliary securing measures, making it prone to displacement between the cover and keyboard during transport due to shaking. This not only affects portability but may also expose the tablet and keyboard to impacts and damage, reducing product lifespan. Therefore, there is an urgent need for a tablet case / keyboard securing structure that can effectively solve these problems and achieve a stable connection. Utility Model Content

[0004] This utility model aims to at least partially solve one of the problems in related technologies. Therefore, one of the objectives of this utility model is to provide a tablet keyboard case that effectively avoids displacement after the protective case and keyboard are closed, improving the ease of use and safety of the tablet keyboard case, and enhancing its protective effect.

[0005] A tablet keyboard case includes a protective shell and a keyboard. The edge of the protective shell is connected to a magnetic element, and the surface of the magnetic element is connected to an anti-slip pad. When the protective shell and the keyboard are closed, the magnetic element is attracted to the keyboard, and the anti-slip pad abuts against the surface of the keyboard.

[0006] Furthermore, the edge of the protective shell is provided with an installation groove, the bottom of the installation groove is provided with a receiving groove, the magnetic suction component is installed in the receiving groove, and the anti-slip pad is installed in the installation groove and covers the receiving groove.

[0007] Furthermore, the protective shell has two mounting slots, and there are two magnetic suction components and two anti-slip pads. The two mounting slots are respectively located at the two corners of the protective shell away from the keyboard, and one magnetic suction component and one anti-slip pad are respectively located in one receiving slot and one mounting slot.

[0008] Furthermore, the anti-slip pad is made of silicone and is bonded to the surface of the magnetic component using an adhesive.

[0009] Furthermore, the surface of the anti-slip mat is provided with anti-slip patterns, which are distributed in a grid pattern.

[0010] Furthermore, the magnetic component and the protective shell are integrally molded by injection molding.

[0011] Furthermore, the tablet keyboard case also includes a magnetic connection assembly, which includes a first magnetic connector disposed on the edge of the protective shell and a second magnetic connector disposed on the edge of the keyboard, as well as a leather case fitted over the second magnetic connector. The protective shell and the keyboard are magnetically connected through the first magnetic connector and the second magnetic connector.

[0012] Furthermore, the leather case has a connecting groove, and the second magnetic member is embedded in the connecting groove. The opening direction of the connecting groove is consistent with the magnetic attraction direction of the first magnetic member and the second magnetic member.

[0013] Furthermore, a support assembly is provided on the back of the protective shell. The support assembly includes a support, a movable connector, and two magnetic plates. One end of the support is rotatably connected to the protective shell. The support has a clearance opening. The edges of the two magnetic plates are rotatably connected. One end of the movable connector is rotatably connected to the protective shell and located below the support. The other end is rotatably connected to one side edge of one of the magnetic plates. The side edge of the other magnetic plate away from the movable connector is rotatably connected to the edge of the clearance opening. When the support rotates away from the protective shell, the two magnetic plates attract each other to drive the movable connector to support the support.

[0014] Furthermore, the shape of the clearance opening is adapted to the shape of the movable connector.

[0015] Compared with the prior art, the above-mentioned technical solution provided in this application has the following advantages: This application sets a magnetic suction component on the edge of the protective shell and connects an anti-slip pad to the surface of the magnetic suction component. While the magnetic suction component is attracted to the keyboard, the anti-slip pad is in close contact with the keyboard surface. By utilizing the friction of the anti-slip pad and the attraction of the magnetic suction component, a double fixing effect is formed, which effectively avoids the displacement problem after the protective shell and the keyboard are closed, and improves the stability and reliability of the product.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1 - Figure 11 As shown, the tablet leather case keyboard 1 provided in this application includes a protective shell 10 and a keyboard 30. The edge of the protective shell 10 is connected to a magnetic member 11, and the surface of the magnetic member 11 is connected to an anti-slip pad 13. When the protective shell 10 and the keyboard 30 are closed, the magnetic member 11 is attracted to the keyboard 30, and the anti-slip pad 13 abuts against the surface of the keyboard 30.

[0035] A magnetic closure 11 is provided along the edge of the protective case 10, along with an anti-slip pad 13, which effectively prevents displacement of the protective case 10 and keyboard 30 when they are closed. When the protective case 10 and keyboard 30 are closed, the magnetic closure 11 attracts the keyboard 30, providing initial connection force; the anti-slip pad 13 abuts against the surface of the keyboard 30, using friction to prevent relative sliding. This not only improves the stability of the product during use and reduces the risk of collision due to displacement during storage and carrying, but also enhances reliability, avoids potential damage to the product caused by frequent displacement, and thus improves the protective effect.

[0036] The magnetic attachment 11, combined with the anti-slip pad 13, greatly enhances the stability of the protective case 10 and keyboard 30 when closed. When the protective case 10 and keyboard 30 are closed, the magnetic attachment 11 initially secures them, while the anti-slip pad 13 adheres tightly to the surface of the keyboard 30, effectively preventing the keyboard 30 from sliding down due to its high coefficient of friction. In everyday use, such as placing the closed tablet case keyboard 1 on an inclined table or carrying it while walking or traveling, this combination ensures that the keyboard 30 remains stable and will not slide down due to gravity, vibration, or shaking.

[0037] Alternatively, the magnetic clasp 11 can be replaced with an electromagnetic adsorption device. By setting a micro battery and control circuit inside the protective case 10, when it is necessary to close the protective case 10 and the keyboard 30, pressing the control button will power on the electromagnetic adsorption device to generate magnetic adsorption of the keyboard 30, which can achieve stronger adsorption force control and can be powered off when adsorption is not needed to avoid interfering with other electronic devices.

[0038] Furthermore, the edge of the protective shell 10 is provided with a mounting groove 15, the bottom of the mounting groove 15 is provided with a receiving groove 17, the magnetic suction component 11 is installed in the receiving groove 17, and the anti-slip pad 13 is installed in the mounting groove 15 and covers the receiving groove 17.

[0039] The protective shell 10 has mounting grooves 15 and receiving grooves 17 on its edges, providing precise mounting positions for the magnetic component 11 and the anti-slip pad 13. The magnetic component 11 is installed in the receiving groove 17, which provides better fixation and prevents it from shaking or falling off. The anti-slip pad 13 is installed in the mounting groove 15 and covers the receiving groove 17, which not only stabilizes its own position but also protects the magnetic component 11 in the receiving groove 17 from external impacts or scratches, extending the service life of the magnetic component 11 and the anti-slip pad 13. It also ensures the stability of the entire fixing structure, thereby improving the overall quality of the product.

[0040] In another embodiment, a magnetic groove structure is adopted on the edge of the protective shell 10, and the magnetic component 11 is directly embedded in the groove and fixed by interference fit. The anti-slip pad 13 is installed by embedded installation. A shallow groove matching the shape of the anti-slip pad 13 is opened on the surface of the magnetic component 11. After the anti-slip pad 13 is embedded in the shallow groove, it is fixed by ultrasonic welding or glue, making the overall structure more compact and stable.

[0041] Furthermore, the mounting groove 15 and receiving groove 17 are not used for the installation of the magnetic component 11 and the anti-slip pad 13. Double-sided tape can be used to first attach the magnetic component 11 to the edge of the protective shell 10, and then attach the anti-slip pad 13 to the surface of the magnetic component 11. This method simplifies the manufacturing process of the protective shell 10 and reduces costs, making it particularly suitable for products with high cost control requirements.

[0042] Furthermore, the protective shell 10 has two mounting slots 15, and two magnetic attachments 11 and two anti-slip pads 13. The two mounting slots 15 are respectively located at the two corners of the protective shell 10 away from the keyboard 30, and one magnetic attachment 11 and one anti-slip pad 13 are respectively located in one mounting slot 15.

[0043] The installation includes two mounting slots 15, a magnetic attachment 11, and an anti-slip pad 13, located at the two corners of the protective case 10 away from the keyboard 30. This design allows for a more even fixing force between the protective case 10 and the keyboard 30 when they are closed. Compared to a single fixing point, the corner fixing method better prevents twisting or shifting between the protective case 10 and the keyboard 30, further enhancing the fixing effect and improving the stability of the product during storage and carrying, providing more reliable protection for the tablet and keyboard 30.

[0044] In another embodiment, instead of providing two mounting slots 15 at the corners of the protective shell 10, one mounting slot 15 is provided at the middle of the top and bottom edges of the protective shell 10. Each mounting slot 15 contains a magnetic attachment 11 and an anti-slip pad 13. This provides a stable fixation effect in certain specific usage scenarios, such as when the tablet case keyboard 1 is placed horizontally.

[0045] Additionally, continuous magnetic strips and anti-slip strips are provided along the edge of the protective case 10, encircling the edge where the protective case 10 contacts the keyboard 30. This structure provides a more uniform fixing force, further enhancing the stability of the protective case 10 and keyboard 30 when closed, making it particularly suitable for professional equipment usage scenarios with extremely high requirements for fixation.

[0046] Furthermore, the anti-slip pad 13 is made of silicone and is bonded to the surface of the magnetic component 11 with an adhesive.

[0047] Silicone material has excellent anti-slip properties and wear resistance. The anti-slip pad 13, made of silicone material, provides greater friction when in contact with the surface of the keyboard 30, enhancing the fixation effect. At the same time, the adhesive bonding to the surface of the magnetic component 11 ensures a tight connection between the anti-slip pad 13 and the magnetic component 11, preventing it from falling off and ensuring the continuous effectiveness of the anti-slip function, further improving the stability and reliability of the product.

[0048] In another embodiment, the anti-slip mat 13 is made of nitrile rubber. Nitrile rubber has good oil resistance, abrasion resistance, and anti-slip properties. In some usage environments where it may come into contact with oil stains, the anti-slip mat 13 made of nitrile rubber can better maintain its anti-slip performance, which is more advantageous than silicone.

[0049] Furthermore, the surface of the anti-slip mat 13 is provided with anti-slip patterns, which are distributed in a grid pattern.

[0050] The grid-like anti-slip texture on the surface of the anti-slip pad 13 greatly increases the contact area with the surface of the keyboard 30. According to the principle of friction, the larger the contact area, the greater the friction. Therefore, this design can significantly improve the friction between the anti-slip pad 13 and the keyboard 30, more effectively prevent relative sliding between the protective case 10 and the keyboard 30, further improve the stability of product use, and reduce the risk of displacement during use, storage, and carrying.

[0051] In another embodiment, the surface of the anti-slip mat 13 is provided with longitudinal and transverse interlaced striped anti-slip patterns. These striped patterns increase friction while making it easier to clean and less prone to accumulating dirt, making it suitable for use in environments with high hygiene requirements.

[0052] Furthermore, the magnetic clasp 11 and the protective shell 10 are integrally molded by injection molding.

[0053] The magnetic component 11 and the protective shell 10 are integrally molded by injection molding, making them a single, strong, and stable connection. Compared to other connection methods, this effectively prevents the magnetic component 11 from falling off, ensuring the reliability of the magnetic fixing function. At the same time, the integral molding process reduces gaps between components, making the product more aesthetically pleasing, more compact in structure, and improving the overall quality and user experience of the product.

[0054] Furthermore, the tablet leather keyboard 1 also includes a magnetic connection assembly 50, which includes a first magnetic connector 51 disposed on the edge of the protective shell 10 and a second magnetic connector 53 disposed on the edge of the keyboard 30, as well as a leather case 55 sleeved on the outside of the second magnetic connector 53. The protective shell 10 and the keyboard 30 are magnetically connected through the first magnetic connector 51 and the second magnetic connector 53.

[0055] With the addition of the magnetic connection component 50, the protective case 10 and the keyboard 30 are magnetically connected via the first magnetic connector 51 and the second magnetic connector 53, greatly enhancing the connection strength. The combined effect of multiple magnetic connection points better resists external forces, preventing the protective case 10 and keyboard 30 from separating during use, storage, and carrying, further improving the product's stability and reliability, and providing users with a more convenient and reliable user experience.

[0056] In another embodiment, a soft rubber protective sleeve is directly disposed on the surface of the second magnetic connector 53. The protective sleeve has a groove that matches the shape of the second magnetic connector 53, and the second magnetic connector 53 is embedded in the groove. The soft rubber protective sleeve can both protect the second magnetic connector 53 and provide a certain degree of anti-slip and cushioning.

[0057] In addition, multiple magnetic attraction points are set on the edges of the protective shell 10 and the keyboard 30 to form a matrix magnetic connection structure. The magnetic strength and position of each magnetic attraction point are precisely designed. Compared with individual first and second magnetic connectors 53, the matrix structure can provide a more uniform magnetic connection force, enhance the stability of the connection between the protective shell 10 and the keyboard 30, and is not easy to separate when subjected to a large external impact.

[0058] Furthermore, the leather sleeve 55 has a connecting groove 551, and the second magnetic member 11 is embedded in the connecting groove 551. The opening direction of the connecting groove 551 is consistent with the magnetic attraction direction of the first magnetic member 11 and the second magnetic member 11.

[0059] The leather case 55 has a connecting groove 551 in which the second magnetic component 11 is embedded. The connecting groove 551 is oriented in the same direction as the magnetic attraction, which ensures the precise positioning of the second magnetic component 11 within the leather case 55. This allows the first and second magnetic components 11 to be better aligned during magnetic connection, enhancing the magnetic attraction effect. This helps improve the stability of the connection between the protective case 10 and the keyboard 30, reduces unstable connections caused by magnetic misalignment, and further improves the product's usability.

[0060] Traditionally, the leather material exits perpendicular to the magnetic attraction direction. When the keyboard 30 separates from the protective shell 10, this perpendicular relationship creates a tearing force, which facilitates the separation of the keyboard 30 and the protective shell 10. This perpendicular exit action causes more of the force generated during separation to damage the magnetic connection. From a mechanical perspective, this perpendicular relationship prevents the separation force from acting parallel to the magnetic surface; instead, a component of the force pulls on the magnetic structure, making it difficult to maintain magnetic stability during separation and causing unnecessary losses. During the tearing process, the magnetic components may become misaligned or slightly deformed, altering the originally precise magnetic pole correspondence and affecting the magnitude and stability of the magnetic force. In this application, the leather material exits in the same direction as the magnetic attraction direction. This maximizes the preservation of magnetic force during the separation of the keyboard 30 from the protective shell 10. This means that during the separation operation, the magnetic force can maintain a relatively stable state, avoiding problems such as premature weakening or failure of the magnetic force due to unreasonable directional design. This may be more conducive to the stability and convenience of the adsorption and separation operation between the protective shell 10 and the keyboard 30.

[0061] Furthermore, a support assembly 19 is provided on the back of the protective shell 10. The support assembly 19 includes a support 191, a movable connector 193, and two magnetic plates 195. One end of the support 191 is rotatably connected to the protective shell 10. The support 191 has a clearance opening 1911. The edges of the two magnetic plates 195 are rotatably connected. One end of the movable connector 193 is rotatably connected to the protective shell 10 and located below the support 191. The other end is rotatably connected to one side edge of one of the magnetic plates 195. The side edge of the other magnetic plate 195 away from the movable connector 193 is rotatably connected to the edge of the clearance opening 1911. When the support 191 rotates away from the protective shell 10, the two magnetic plates 195 attract each other to drive the movable connector 193 to support the support 191.

[0062] Specifically, the support assembly 19 on the back of the protective case 10 provides support for the tablet keyboard 1. When the support 191 rotates away from the protective case 10, the two magnetic plates 195 attract each other, causing the movable connector 193 to support the support 191. Users can place the tablet on the support 191 and perform operations such as watching videos and working at a suitable angle, meeting the user's needs in different scenarios, greatly expanding the product's usage scenarios, and improving the product's practicality and user experience.

[0063] Furthermore, the swing-open mechanism of the stand assembly 19 greatly enhances user convenience. Traditional stand 191 opening methods often require manual adjustment of multiple components, which is cumbersome and time-consuming. However, the stand assembly 19 of this invention, through the clever design of the magnetic plate 195 and the movable connector 193, allows the user to quickly open and automatically support the stand 191 with a simple swing of the protective shell 10. In scenarios requiring quick use of the tablet for video conferencing or watching videos, this convenient opening method saves significant time and improves user efficiency. Simultaneously, the swing-open operation adds to the product's fun and technological appeal, increasing user satisfaction.

[0064] Furthermore, the shape of the clearance opening 1911 is adapted to the shape of the movable connector 193.

[0065] The clearance 1911 is shaped to fit the movable connector 193, ensuring smooth and unobstructed movement of the movable connector 193 during the rotation and support of the bracket 191. This helps improve the stability and reliability of the bracket assembly 19, making the bracket 191 more stable when supporting the plate, reducing swaying and displacement, providing a better user experience, and further enhancing the overall performance of the product.
