Description

Technical Field

[0001] This utility model relates to the field of tablet computer stands, and in particular to a tablet computer protective case. Background Technology

[0002] As tablets become increasingly popular in various scenarios such as work, study, and entertainment, users' functional needs for protective cases have expanded from simple scratch and drop protection to include support and angle adjustment. Traditional tablet cases are mostly made of silicone, TPU, or hard plastic, providing basic protection through a wraparound design. However, their structures generally do not consider ergonomics, leading to neck fatigue and a poor user experience during prolonged viewing or operation.

[0003] To address the lack of support, some manufacturers have added simple folding stands or magnetic strips to the back of the protective case, allowing the tablet to stand upright on a table. However, such designs are limited by hinge travel or magnetic attachment methods, offering only one or two fixed support angles (such as 60° or 75°), and cannot be flexibly adjusted according to different user postures such as sitting, standing, or lying down. Furthermore, gaps exist between the stand and the case when folded, making it prone to dust accumulation and increasing the overall thickness, thus reducing portability.

[0004] While existing technologies employ complex structures such as gear clips and multi-segment slide rails to achieve multi-angle adjustments, they suffer from numerous components, high mold costs, and wear and tear on the clips leading to loosening after prolonged use, making it difficult to balance reliability, lightweight design, and cost control. Therefore, the market urgently needs a solution with a simple structure, continuously adjustable support angle, and integrated with the protective case to improve the comfort and convenience of using tablets in various scenarios.

By utilizing the multiple flip angles and flip combinations of the first and second support frames, the case can provide support at multiple angles, enabling the protective case to support the tablet computer for writing and drawing, as well as for raising it, thus meeting various user needs and improving the user experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tablet computer protective case includes a housing for accommodating a tablet computer and a support frame for supporting the housing. The support frame includes a first support frame and a second support frame. The first support frame is hinged to the back of the housing in a flip-out manner. The second support frame is hinged to the middle of the first support frame in a flip-out manner relative to the first support frame. A clearance space is reserved on the first support frame for the second support frame to flip and reset. After the second support frame is flipped and reset, it is located in the clearance space.

[0008] As a preferred embodiment: the first support frame includes an integrally connected upper frame and a lower frame, the overall width of the lower frame is smaller than the overall width of the upper frame, and the gap is narrowed inward at the connection between the lower frame and the upper frame to form the clearance space.

[0009] As a preferred embodiment, the upper end of the second support frame is hinged to the upper end of the clearance space.

[0010] As a preferred embodiment: the width of the frame strip of the second support frame is the same as the width of the frame strip of the upper frame, and after the second support frame is flipped and repositioned in the clearance space, the two sides of the second support frame are flush with the two sides of the upper frame.

[0011] As a preferred embodiment: the second support frame has an accommodating area that is adapted to the lower frame, and after the second support frame is flipped and reset, the lower frame is located in the accommodating area; and notches are respectively provided on the lower edges of the lower frame and the second support frame to facilitate hand-held flipping.

[0012] As a preferred embodiment: a connecting strip is provided laterally on the back of the housing, and the first support frame is hinged to the connecting strip in a flip-up manner.

[0013] As a preferred embodiment: the back of the housing is recessed to accommodate the connecting strip, the first support frame and the second support frame.

[0028] This utility model is as follows Figures 1 to 7As shown, a tablet computer protective case includes a housing 10 for housing the tablet computer and a support frame 20 for supporting the housing 10, wherein:

[0029] The front of the housing 10 has a receiving groove, in which the tablet computer can be embedded. The support frame 20 includes a first support frame 21 and a second support frame 22. The first support frame 21 is hinged to the lower lateral position on the back of the housing 10 (the hinge point of the first support frame 21 is located slightly above the lateral edge of the housing 10). The second support frame 22 is hinged to the middle of the first support frame 21 relative to the first support frame 21. A clearance space 211 is reserved on the first support frame 21 for the second support frame 22 to flip and reset. After the second support frame 22 is flipped and reset, it is located in the clearance space 211, so as to keep it flush with the first support frame 21. The hinge joints between the first support frame 21 and the back of the housing 10, and between the second support frame 22 and the first support frame 21, are both hinge joints. Other hinge joints, such as pivot joints, can also be used. The use of hinge joints not only allows users to freely control the viewing angle, but also allows the tablet case to have more support options and greater playability when used in combination. The position layout, reasonable limit, and mutual restraint relationship of the hinge joints enable the tablet case to achieve the purpose of raising and supporting the tablet.

[0030] The first support frame 21 has a rotation angle range of 0-115° relative to the housing 10, and the second support frame 22 has a rotation angle range of 0-90° relative to the first support frame 21. The first support frame 21 and the second support frame 22 can be rotated arbitrarily within the above angle range. A damping ring or the like can be provided on the inner side of the hinge position to increase the rotation friction and keep the rotation angle of the first support frame 21 and the second support frame 22 constant.

[0031] The first support frame 21 includes an integrally connected upper frame 212 and lower frame 213. The overall width of the lower frame 213 is smaller than the overall width of the upper frame 212. Specifically, the lower frame 213 and the upper frame 212 narrow inward at the connection point to form the clearance space 211. The upper end of the second support frame 22 is hinged to the upper end of the clearance space 211. The width of the frame strip of the second support frame 22 is the same as the width of the frame strip of the upper frame 212. After the second support frame 22 is flipped and placed back in the clearance space 211, the two sides of the second support frame 22 are flush with the two sides of the upper frame 212, and the overall structure is neater after folding. The second support frame 22 has a receiving area 221 that is adapted to the lower frame. After the second support frame 22 is flipped and reset, the lower frame 213 is located in the receiving area 221 to reduce the thickness of the support frame after folding, reduce the space occupied, and improve portability. Notches 23 are provided on the lower edges of the lower frame 213 and the second support frame 22 to facilitate hand-held flipping, so that the first support frame 21 and the second support frame 22 can be easily flipped open in the folded state.

[0032] A connecting strip 11 is laterally arranged on the back of the housing 10. The first support frame 21 is hinged to the connecting strip 11 in a flip-up manner. It should be noted that the first support frame 21 can also be directly hinged to the back of the housing 10. The back of the housing 10 is recessed with a receiving recess 12 for accommodating the connecting strip 11, the first support frame 21, and the second support frame 22. When the first support frame 21 and the second support frame 22 are flipped and folded into the receiving recess 12, both the first support frame 21 and the second support frame 22 are located inside the receiving recess 12, so as to reduce the thickness of the protective shell after the support frame is folded and further improve portability. The receiving recess 12 is rectangular, and the first support frame 21 and the second support frame 22 are also rectangular after being flipped and folded, resulting in a neat overall structure that is easy to assemble and disassemble.

[0033] This protective case can be used in the following ways:

[0034] 1. Flip the first support frame 21 relative to the housing 10 as follows: Figure 2 As shown, the flip angle range is 0-115°, and the first support frame 21 provides support for the tablet computer.

[0035] 2. Flip the first support frame 21 as follows Figure 1 After achieving the shown state, turn the protective case around to obtain another support angle for the tablet computer from the first support frame 21, as shown. Figure 3 As shown.

[0036] 3. The first support frame 21 remains stationary, while the second support frame 22 is flipped open relative to the first support frame 21. The flip angle range is 0-90°, and the second support frame 22 provides 25° support for the tablet computer. Figure 4 As shown, it can be used for writing and drawing operations.

[0037] 4. Flip open the second support frame 22 relative to the first support frame 21, and then flip open the first support frame 21 relative to the housing 10. The second support frame 22 and the lower frame 213 of the first support frame 21 provide support for the tablet computer and also help to raise the tablet computer. Figure 5 As shown.

[0038] 5. In the first support configuration, placing the tablet vertically provides a 70° support angle. Figure 6 As shown.

[0039] 6. In the fourth support configuration, placing the tablet vertically provides a 60° support angle, such as... Figure 7 As shown.

[0040] The key design feature of this invention is a bracket frame with a first support frame and a second support frame on the back of the tablet protective case. This bracket frame utilizes the multiple flip angles and combinations of the first and second support frames to provide support for the case at various angles. Compared to existing products, this adds writing and drawing support and height support functions to the existing horizontal and vertical functions, thus avoiding the shortcomings of existing products where the tablet's functions cannot be maximized due to the limited usage angle. Structurally, compared to existing products, it adds a reasonably distributed set of hinges, enabling the tablet protective case to support more support methods, meet various user needs, and improve the user experience.

[0041] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
