[0036] The present invention is described in further detail below with reference to the accompanying drawings:

[0037] like Figure 1-3 As shown, according to the utility model, a tablet protective cover based on double hinges and bidirectional support is provided, which includes a protective cover body 1 and a bracket part 2, wherein the bracket part 2 is arranged on the back of the protective cover body 1, the protective cover body 1 is used to cover the tablet computer, and the back of the protective cover body 1 is provided with a receiving groove 11 for accommodating the bracket part 2; the bracket part 2 includes a bidirectional hinge 21, an upper hardware bracket 22 and a lower hardware bracket 23; the bidirectional hinge 21 is fixed on the protective cover body 1, the first free end of the bidirectional hinge 21 is connected to the upper hardware bracket 22, and the second free end of the bidirectional hinge 21 is connected to the lower hardware bracket 23; the inclination of the protective cover body 1 is adjusted by folding the upper hardware bracket 22 or the lower hardware bracket 23 downward or upward.

[0038] This embodiment features a simple structure and easy operation. The upper and lower hardware brackets 22 and 23 are connected by a bidirectional hinge 21. The upper and lower hardware brackets 22 and 23 can be folded downward or upward to adjust the inclination of the protective cover body 1, thus achieving a bidirectional support function. Whether the user is watching videos, live broadcasts, or movies, or performing operations such as writing or drawing, they can flexibly adjust the angle of the tablet according to their needs. For example, they can choose to watch from different perspectives, such as sitting, looking down, or lying down, effectively improving user convenience in different usage scenarios. The bidirectional hinge 21 connecting the upper and lower hardware brackets 22 and 23 effectively prevents deformation and abnormal rotation noise, improves durability and stability, and extends the product's service life.

[0039] Specifically:

[0040] like Figure 4 As shown, in the above embodiment, the shape of the receiving groove 11 preferably matches the shape of the bracket portion 2. Furthermore, the height of the two-way hinge 21, upper hardware bracket 22, and lower hardware bracket 23 is no higher than the depth of the receiving groove 11. This arrangement ensures that when the protective case body 1 accommodates the bracket portion 2, the bracket portion 2 does not protrude, reducing the overall size and thickness, making it easier to carry.

[0041] In the above embodiment, preferably, the number of bidirectional hinges 21 is two, and the two bidirectional hinges 21 are arranged at intervals on the back of the protective cover body 1 along the long side direction of the protective cover body 1, and are both arranged in the accommodating grooves 11 on the corresponding sides; the two ends of the upper hardware bracket 22 are respectively connected to the first free ends of the two bidirectional hinges 21; the two ends of the lower hardware bracket 23 are respectively connected to the second free ends of the two bidirectional hinges 21.

[0042] In this embodiment, the use of two bidirectional hinges 21 effectively distributes the tablet's weight load, evenly transmitting force to the protective cover body 1 and avoiding localized stress concentration. This ensures that the entire support structure maintains high stability under different usage conditions, significantly reducing the risk of the tablet tipping or sliding due to unstable support, and providing users with a safe and reliable usage environment.

[0043] like Figure 5-6 As shown, in the above embodiment, the bidirectional hinge 21 preferably includes a fixed hinge 211, a first movable hinge 212, and a second movable hinge 213. The fixed hinge 211 is placed in the receiving groove 11 and connected to the protective cover body 1 via a fixed hinge connecting plate 215. A shaft core 214 is provided on one side of the fixed hinge 211, and the axial direction of the shaft core 214 is parallel to the long side of the protective cover body 1. The first movable hinge 212 and the second movable hinge 213 are rotatably mounted on the shaft core 214. The first movable hinge 212 is connected to the upper hardware bracket 22, and the second movable hinge 213 is connected to the lower hardware bracket 23. The inclination of the protective cover body 1 can be adjusted by folding the upper hardware bracket 22 or the lower hardware bracket 23.

[0044] During actual installation, the two fixed hinges 21 are installed in the accommodating groove on the back of the protective cover body 1 at intervals along the long side direction of the protective cover body 1, and the two fixed hinges 21 are distributed along the same straight line. The bottom ends of the two fixed hinges are provided with an axis core 214, and the axial direction of the axis core 214 is parallel to the long side direction of the protective cover body 1. The first movable hinge 212 is placed above the axis core 214, and the second movable hinge 213 is placed below the axis core 214, and the first movable hinge 212 and the second movable hinge 213 are both rotatably connected to the axis core 214. When the first movable hinge 212 and the second movable hinge 213 are stored in place, the first movable hinge 212 and the second movable hinge 213 are respectively stored in the upper and lower halves of the accommodating groove 11.

[0045] In the above embodiment, preferably, the bidirectional hinge 21 is made of metal, has wear resistance, balanced force, and good rotation stability.

[0046] In the above embodiment, preferably, both the upper hardware bracket 22 and the lower hardware bracket 23 are trapezoidal, with the upper hardware bracket 22 being shorter than the lower hardware bracket 23. This arrangement helps maintain stable support at various tilt angles; the higher lower hardware bracket 23 provides a support point further back at larger tilt angles, enhancing stability; the relatively lower upper hardware bracket 22 is more effective at smaller tilt angles or when the tablet needs to be placed more horizontally. Together, the two can cover a wide range of angle adjustments and better fit within the storage slot when stored, reducing the overall thickness.

[0047] In the above embodiment, preferably, the angle adjustment range of the upper hardware bracket 22 and the lower hardware bracket 23 are both 100°-130°.

[0048] like Figure 7-9 As shown, in the above embodiment, preferably, when a tablet computer is needed for writing and drawing, the lower hardware bracket 23 can be kept unchanged, and the upper hardware bracket 22 can be folded downward to make the protective cover body 1 present a relatively gentle tilt angle to meet the user's operating needs.

[0049] like Figure 10-12 As shown, in the above embodiment, preferably, when a tablet computer is needed to play videos or watch movies, the upper hardware bracket 22 can be kept unchanged, and the lower hardware bracket 23 can be folded upward to make the protective cover body 1 present a relatively large tilt angle to meet the user's operating needs.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
