Description

Technical Field

[0001] This utility model relates to protective covers for electronic products, and more particularly to a flexibly adjustable tablet computer stand cover. Background Technology

[0002] With the rapid development of mobile internet technology, tablet computers, with their lightweight, portability, and diverse functions, are playing an increasingly important role in people's daily work, study, and entertainment. To enhance the user experience—for example, when watching videos, conducting video conferences, reading ebooks, or creating artwork—users often need to prop up their tablets at a specific tilt angle to achieve a comfortable viewing angle and convenient operating posture. Therefore, various protective cases or stands for supporting tablet computers have emerged. Currently, the mainstream solutions on the market mainly include the following:

[0003] The first type utilizes the protective cover's own structure to fold and form a triangular support structure. For example, some protective cases have front covers designed to fold in sections, using magnetic attraction or friction to secure them into a triangle to support the tablet. The advantage of this design is its simple structure and high degree of integration with the protective case. However, its disadvantages are also quite obvious: the support angles it provides are very limited, usually only one or two fixed angles, which cannot meet the user's needs for fine-tuning and diversifying the angle in different usage scenarios (such as typing, drawing, and watching movies), resulting in poor flexibility.

[0004] The second type involves installing a turntable on the back of the protective case, with a ring bracket pivotally connected to the turntable. This structure allows for support at different angles; however, it requires the turntable and ring bracket to work together, and the turntable itself needs to be mounted on the back of the protective case via a complex pivoting structure. This makes the structure complex and suffers from poor reliability and durability. Furthermore, the protective case needs to be thicker, resulting in a bulky overall design that fails to meet the demands of some consumers for lightweight, simple, and aesthetically pleasing designs.

[0005] Therefore, existing tablet stand covers cannot simultaneously meet the requirements of a wide range of flexible angle adjustment capabilities and a simple, reliable, lightweight, and convenient structure. Utility Model Content

[0006] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a flexibly adjustable tablet computer stand cover.

[0021] The first bushing portion is fitted over a portion of the damping rubber ring, and the second bushing portion is fitted over another portion of the damping rubber ring, with the damping rubber ring in a compressed state.

[0022] According to one embodiment of the present invention, one side of the fixed page has two spaced third bushing portions, the cross-section of the two third bushing portions is a non-circular cross-section, and the rotating shaft has two non-circular ends;

[0064] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a flexibly adjustable tablet computer stand cover.

[0065] Reference Figures 1 to 8 As shown, the adjustable tablet computer stand cover provided according to the embodiment of the present utility model includes a protective cover 10, a first bracket 20 and a second bracket 30.

[0066] Specifically, the protective case 10 is suitable for being worn over a tablet computer. The shape and size of the protective case 10 are matched to a specific model of tablet computer, and it can tightly cover or snap onto the edges and back of the tablet computer, providing the tablet computer with protection against drops and scratches.

[0067] The protective sleeve 10 has a damping hinge 11 on its back side. The damping hinge 11 includes a fixing hinge 111, a first hinge 112, and a second hinge 113. The fixing hinge 111 is fixedly mounted on the protective sleeve 10. Preferably, the damping hinge 11 is located at the middle position along the length of the protective sleeve 10. The fixing hinge 111 can be firmly installed on the back side of the protective sleeve 10 by means of adhesive, screw fixing, ultrasonic welding, or integral injection molding with the protective sleeve 10. The fixing hinge 111 remains stationary when the first bracket 20 and the second bracket 30 are folded and stored.

[0068] The first bracket 20 is connected to the first hinge 112 and is pivotable about the axis of the damping hinge 11, which extends along the length of the protective sleeve 10. The second bracket 30 is connected to the second hinge 113 and is pivotable about the axis of the damping hinge 11.

[0069] In other words, both the first bracket 20 and the second bracket 30 can pivot relative to the protective sleeve 10 around the common axis of the damping hinge 11. Because the damping hinge 11 provides damping rotation, when the first bracket 20 and / or the second bracket 30 are opened to any angle by the user, the damping force generated by the damping hinge 11 can overcome the weight of the first bracket 20 and the second bracket 30 themselves, as well as the weight of the tablet computer, allowing them to remain stably in that position. This achieves a smooth, continuous, and stepless angle adjustment function. Users can precisely adjust the tablet computer to the most comfortable viewing angle according to their actual needs, such as watching videos, making video calls, or inputting text.

[0070] The second bracket 30 and the first bracket 20 are arranged opposite to each other in the width direction of the protective sleeve 10, and the dimension of the second bracket 30 in the width direction is smaller than the dimension of the first bracket 20 in the width direction.

[0071] When not in use, the first stand 20 and the second stand 30 can be folded flat and stored on the back of the protective case 10, flush with or slightly protruding from the surface of the protective case 10, maintaining the overall slim and simple design. More importantly, because the second stand 30 is designed to be smaller in width than the first stand 20, the first stand 20 is primarily responsible for supporting the tablet at large angles, i.e., the angle between the tablet and the surrounding surface. The second stand 30, on the other hand, is primarily responsible for supporting the tablet at smaller angles.

[0072] When the tablet needs to be supported at a large angle (e.g., near vertical), the user can unfold the first stand 20 to create a wide and stable large-angle support. When a very small angle is needed (e.g., near flat for drawing or writing), the second stand 30 can be unfolded to create a very gentle small-angle support. During use, the user can selectively unfold either the first stand 20 or the second stand 30 depending on the surface on which the tablet is placed, to suit their needs.

[0073] According to the adjustable tablet stand cover provided in this embodiment, the damping hinge 11 enables smooth, stepless angle adjustment, allowing users to stably support the tablet at any angle. Simultaneously, the design of two independent first supports 20 and second supports 30 (one large and one small) significantly expands the achievable stable support angle range through an asymmetrical support method. More importantly, this dual-support structure, pivoting around a single axis, offers advantages over complex turntable-type support structures in terms of simplicity, reliability, and durability, while maintaining the overall thinness and aesthetics of the protective cover 10, avoiding a bulky structure. Therefore, the tablet stand cover of this invention integrates a wide range of flexible adjustment capabilities with a simple and reliable structure, significantly improving the user experience.

[0074] Reference Figures 2 to 3 As shown, in one embodiment of the present invention, the protective sleeve 10 has a storage groove H101 on the back. The first bracket 20 and the second bracket 30 are both sheet-like parts. When the first bracket 20 and the second bracket 30 are in the closed state, the first bracket 20 and the second bracket 30 are closed in the storage groove H101.

[0075] When the user does not need to use the support function, the first support 20 and the second support 30 can be pivoted inward about the axis of the damping hinge 11 until they are completely flat. In this retracted state, the sheet-like structure of the first support 20 and the second support 30 is precisely embedded and accommodated in the storage groove H101 on the back of the protective cover 10. Preferably, when the support is fully retracted, its exposed surface is flush or substantially flush with the outer surface around the storage groove H101 of the protective cover 10, thereby making the entire back of the protective cover 10 flatter.

[0076] In this embodiment, a storage slot H101 is provided on the back of the protective case 10, which improves the overall aesthetics and integration of the product. When the first bracket 20 and the second bracket 30 are folded up, the back of the protective case 10 is flatter, which is not only more visually concise, but also makes it easier to lay the device flat or store it in a bag, providing users with a simpler, more durable and convenient experience. In addition, storing the first bracket 20 and the second bracket 30 in the storage slot H101 can also effectively protect the first bracket 20 and the second bracket 30 from wear, scratches and accidental impacts during daily use, significantly extending their service life.

[0077] Reference Figures 3 to 5 As shown in one embodiment of this utility model, both the first bracket 20 and the second bracket 30 are U-shaped structures. Two damping hinges 11 are provided, spaced apart along the length of the back of the protective sleeve 10. The two ends of the first bracket 20 are respectively connected to the first hinges 112 of the two damping hinges 11, and the two ends of the second bracket 30 are respectively connected to the second hinges 113 of the two damping hinges 11. In this way, both the first bracket 20 and the second bracket 30 are connected to the protective sleeve 10 through two spaced-apart fulcrums. When the user unfolds the first bracket 20 and the second bracket 30, the two ends of the first bracket 20 and the two ends of the second bracket 30 pivot synchronously around the axes of the two damping hinges 11. The two damping hinges 11 work together to provide a smooth damping torque, achieving stable hovering at any angle.

[0078] This embodiment employs a structural design with double-damped hinges 11 and U-shaped first and second supports 20 and 30. On one hand, this enhances overall support stability. Compared to a single-hinge central pivot structure, the distributed layout of the double hinges creates a wider mechanically fixed structure, more effectively resisting lateral thrust and significantly reducing tablet swaying during support, providing users with a stable support experience. On the other hand, it improves the strength and durability of the structure. The load supporting the tablet is evenly distributed across the two damped hinges 11, reducing stress concentration in individual components, making the entire support more robust, capable of withstanding greater loads, and less prone to loosening or damage under long-term repeated use.

[0079] Reference Figures 4 to 5As shown, in one embodiment of the present invention, the damping hinge 11 further includes a pivot 114, which is fixedly disposed on one side of the fixed hinge; the first hinge 112 has a first bushing portion 1121, and the second hinge 113 has a second bushing portion 1131. The first bushing portion 1121 and the second bushing portion 1131 are sleeved on the pivot 114 and are rotatable relative to the pivot 114. A damping structure is provided between the first bushing portion 1121 and the second bushing portion 1131 and the pivot 114.

[0080] In other words, both the first bushing 1121 and the second bushing 1131 are hollow cylindrical structures, and their inner diameters match the outer diameter of the rotating shaft 114. During assembly, the first bushing 1121 and the second bushing 1131 are fitted onto the fixed rotating shaft 114, and can rotate freely around the center line of the rotating shaft 114 independently and without interference.

[0081] A damping structure is disposed between the inner walls of the first bushing portion 1121 and the second bushing portion 1131 and the outer wall of the rotating shaft 114. This damping structure can be implemented in various ways. For example, it can be achieved by filling the space between the rotating shaft 114 and the bushing portion with high-viscosity damping grease, utilizing the viscous effect of the grease to generate a torque that resists rotation during rotation. Another more common and reliable approach is to provide one or more friction rings or similar structures made of materials with a high coefficient of friction (such as modified engineering plastics, felt, or specific metals).

[0082] The design of this damping structure, through the fit between the shaft and sleeve and frictional or viscous damping, provides a reliable damping torque, ensuring the stability and durability of the entire damping hinge 11 under long-term repeated use. In addition, the first support 20 and the second support 30 move independently on the same rotating shaft 114, and its structure is compact, easy to process and assemble.

[0083] Reference Figure 5 As shown, in one embodiment of this utility model, the damping structure includes a plurality of damping rubber rings 115. Preferably, the damping rubber rings 115 are made of one of polyurethane, synthetic rubber, nylon, or modified engineering plastics.

[0084] The rotating shaft 114 is provided with a plurality of annular grooves H11, which are spaced apart along the axial direction of the rotating shaft 114 and correspond one-to-one with a plurality of damping rubber rings 115. Each damping rubber ring 115 is fitted in an annular groove H11, and the outer diameter of the damping rubber ring 115 is larger than the outer diameter of the annular groove H11. A first bushing portion 1121 is fitted over a portion of the damping rubber rings 115, and a second bushing portion 1131 is fitted over another portion of the damping rubber rings 115, and the damping rubber rings 115 are in a compressed state.

[0085] During assembly, the damping rubber rings 115 are respectively fitted into the annular grooves H11 corresponding to the rotating shaft 114. Due to their own elasticity, the damping rubber rings 115 are firmly embedded in the annular grooves H11, and a portion of their outer circumference protrudes radially from the surface of the rotating shaft 114 due to their larger outer diameter, forming a series of raised soft rings. When the movable first hinge 112 and second hinge 113 are installed onto the rotating shaft 114, the inner hole of the first bushing portion 1121 is fitted onto one part of the rotating shaft 114 section containing the damping rubber rings 115, while the inner hole of the second bushing portion 1131 is fitted onto the other part of the rotating shaft 114 section containing the damping rubber rings 115. The inner diameter of the first bushing portion 1121 and the second bushing portion 1131 is smaller than the outer diameter of the damping rubber rings 115 after they are installed on the rotating shaft 114, but larger than the diameter of the rotating shaft 114 itself. Therefore, when the first bushing 1121 and the second bushing 1131 are fitted, their inner walls exert a radial compressive force on the damping ring 115, causing the damping ring 115 to be in a compressed deformation state. It is this compression that generates a positive pressure between the outer surface of the damping ring 115 and the inner walls of the first bushing 1121 and the second bushing 1131. Combined with the high coefficient of friction of the damping ring 115 material itself, this forms a frictional damping torque sufficient to support the weight of the tablet computer, effectively preventing the free rotation of the first support 20 and the second support 30.

[0086] The damping structure, which uses an annular groove H11 in conjunction with a damping rubber ring 115, is extremely simple in structure and provides a noticeable sense of rotational damping. Furthermore, the elastic material properties of the damping rubber ring 115 make the rotation process smoother and quieter, improving the user's tactile experience when adjusting the angle.

[0087] Reference Figures 4 to 5 As shown, in one embodiment of the present invention, the fixed page 111 has two spaced third bushing portions 1111 on one side, the cross-section of the two third bushing portions 1111 is a non-circular cross-section, and the rotating shaft 114 has two non-circular ends 1141.

[0088] One of the two non-circular ends 1141 is positioned and engaged with one of the two third bushing portions 1111, and the other of the two non-circular ends 1141 is positioned and engaged with the other of the two third bushing portions 1111, so that the rotating shaft 114 is fixed relative to the fixed page 111; the first bushing portion 1121 and the second bushing portion 1131 are located between the two third bushing portions 1111.

[0089] For example, the inner cross-section of the first bushing portion 1121 can be a D-shaped cross-section (i.e., composed of a plane and a circular arc), a regular polygonal cross-section, or a cross-section with a keyway. Correspondingly, both ends of the rotating shaft 114 are also machined to form two non-circular ends 1141 that match the inner cross-sections of the two third bushing portions 1111. The middle portion of the rotating shaft 114 remains cylindrical for mounting the rotatable first bushing portion 1121 and the second bushing portion 1131. Due to the mutual matching of cross-sectional shapes, a positioning fit is formed between the non-circular ends 1141 of the rotating shaft 114 and the non-circular inner holes of the third bushing portions 1111. This fit utilizes geometric interlocking to achieve relative fixation between the rotating shaft 114 and the fixed page 111, meaning that the rotating shaft 114 and the third bushing portions 1111 cannot rotate circumferentially.

[0090] In this embodiment, a non-circular cross-section structure is used to lock and fix the rotating shaft 114 to the fixed hinge 111. Furthermore, this structure can withstand torque far exceeding that of the intended use scenario, ensuring the stationary position of the rotating shaft 114. Simultaneously, it guarantees the reliability and stability of the damped rotation of the first hinge 112 and the second hinge 113. In addition, the two spaced third bushing portions 1111 greatly enhance the installation rigidity and structural stability of the rotating shaft 114, thereby ensuring that the entire damping hinge 11 will not wobble under various support angles, maintaining better stability.

[0091] Reference Figure 8 As shown, in some embodiments of this utility model, the protective cover 10 includes a back plate 101, an inner frame 102, and an outer soft rubber cover 103. The outer soft rubber cover 103 is fitted over the back plate 101 and the inner frame 102 to define a space suitable for accommodating a tablet computer.

[0092] The back panel 101 is typically made of high-strength, impact-resistant engineering plastics (such as polycarbonate PC) or lightweight metals (such as aluminum alloy), forming the skeleton of the protective case 10. The inner frame 102 is also made of a rigid material, typically a hard engineering plastic. The internal contour of the inner frame 102 matches the edge of the tablet computer, which is securely "embedded" within the rigid inner frame 102. The outer soft rubber sleeve 103 is the outermost layer of the protective case 10, made of a flexible material with high elasticity and excellent shock absorption properties, such as thermoplastic polyurethane (TPU) or silicone. This outer soft rubber sleeve 103 tightly covers the back panel 101 and the inner frame 102, forming a complete and compatible protective case 10 for the tablet computer.

[0093] Through the aforementioned structure, the back panel 101, inner frame 102, and outer soft rubber sleeve 103 together define a reliable and snug-fitting housing space. The rigid back panel 101 and inner frame 102 provide scratch and impact protection for the tablet computer, while the outer soft rubber sleeve 103 absorbs and disperses the impact energy from drops and collisions. Furthermore, the elastic tension of the outer soft rubber sleeve 103 further secures the inner shell and the device together firmly, preventing loosening and improving the protective effect.

[0094] Reference Figure 6 As shown, in one embodiment of this utility model, the outer soft rubber sleeve 103 has a pen-holding groove H102 on at least one side in the length or width direction, which can hold the stylus. When the user needs to store the stylus, they only need to align the stylus with the opening of the pen-holding groove H102 and apply a certain pressure. The elastic sidewall of the pen-holding groove H102 will expand outward, allowing the stylus to be inserted into the groove. In this way, the user can carry and manage the tablet computer and stylus as a whole, and access them at any time, greatly improving the convenience of use.

[0095] In one embodiment of this utility model, the fixing page 111 is connected to the protective sleeve 10 by a first screw, the first bracket 20 is connected to the first hinge 112 by a second screw, and the second bracket 30 is connected to the second hinge 113 by a third screw.
