If the specific posture changes, the directional indication will also change accordingly.

It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

Please refer to Figures 1 to 5. A protective case 10 provided in one embodiment of the utility model includes a shell 12 and a bracket 14. The shell 12 has a receiving cavity 16 for storing electronic devices such as tablets and mobile phones. The bracket 14 is installed on the shell 12 to support the shell 12, thereby supporting the electronic device located in the shell 12 and freeing the user's hands.

The housing 12 includes a back plate 18 and a frame 20. The frame 20 is connected to the outer periphery of the back plate 18 and encloses the back plate 18 to form a receiving cavity 16. The bracket 14 is mounted on the back plate 18. It can be understood that the back plate 18 and the frame 20 can be integrally formed or assembled separately.

The back plate 18 is provided with a mounting hole 22, and the bracket 14 is received in the mounting hole 22, thereby reducing the overall thickness of the protective shell 10 and reducing the abruptness of the bracket 14. Preferably, the outer surface of the bracket 14 away from the accommodating cavity 16 is flush with the outer surface of the back plate 18 away from the accommodating cavity 16, so that the overall thickness of the protective shell 10 is the sum of the thickness of the back plate 18 and the frame 20.

It can be understood that the mounting hole 22 can pass through the back plate 18 or not. In the present embodiment, the mounting hole 22 passes through the back plate 18 so that the depth of the mounting hole 22 reaches the maximum, that is, the thickness of the back plate 18, so as to accommodate the bracket 14.

In one embodiment, the bracket 14 includes a base 24 and a support member 26 rotatably mounted on the base 24. The base 24 is received in the mounting hole 22, and the support member 26 is located on a side of the base 24 away from the accommodating cavity 16. After the support member 26 rotates a certain angle relative to the base 24, an angle is formed between the support member 26 and the back plate 18, and the support member 26 can cooperate with the back plate 18 to play the effect of supporting the electronic device. Moreover, the support angle, that is, the tilt angle of the electronic device, will also change when the support member 26 rotates at a different angle relative to the base 24, so as to play the effect of adjusting the tilt angle of the electronic device.

A matching rotating connection structure is provided between the base 24 and the back plate 18. The base 24 is rotatably connected to the back plate 18 through the rotating connection structure, and the rotating connection structure can limit the base 24 in the axial direction of the mounting hole 22, that is, in the direction perpendicular to the surface of the back plate 18 close to the accommodating cavity 16. By providing a rotating connection structure between the base 24 and the back plate 18, the base 24 and the back plate 18 are rotatably connected. When the base 24 is rotated relative to the back plate 18, the base 24 will drive the support member 26 to rotate together, thereby adjusting the position of the support member 26 to change the support direction of the support member 26, thereby supporting the electronic device horizontally or vertically. The bracket 14 can not only adjust the support angle, but also adjust the support direction to facilitate user use. In addition, the rotating connection structure can also form a limiting effect on the bracket 14 in the axial direction of the mounting hole 22 while realizing the rotational cooperation, so as to prevent the support member 26 from falling off from the mounting hole 22.

Please refer to Figures 6 to 9. In one embodiment, the rotating connection structure is a concave-convex structure, which includes a groove 28 and a protrusion 30. The protrusion 30 is arranged on the back plate 18, and the groove 28 is arranged on the base 24. The protrusion 30 is movably inserted into the groove 28 and can slide in the groove 28 along the circumference of the groove 28, so that the base 24 is rotatably installed on the back plate 18 to achieve the effect of adjusting the support angle. The groove 28 and the protrusion 30 have a simple structure, which can reduce the manufacturing difficulty and facilitate production.

In other embodiments, a protrusion 30 may be provided on the base 24 and a groove 28 may be provided on the back plate 18 .

In this embodiment, the protrusion 30 is arranged on the circumferential inner wall of the mounting hole 22, and the groove 28 is arranged on the circumferential outer wall of the base 24. In the axial direction of the mounting hole 22, the protrusion 30 is located in the middle of the mounting hole 22, and the groove 28 is located in the middle of the base 24, so that after the protrusion 30 is inserted into the groove 28, it can achieve both the effect of rotational cooperation and the effect of axial limitation.

In this embodiment, the groove 28 is a closed annular groove, so that the base 24 can rotate 360 degrees relative to the back plate 18.

In one embodiment, the base 24 includes a relatively fixed base body 32 and a cover body 34, and a gap exists between the base body 32 and the cover body 34 in the axial direction of the mounting hole 22 to form a groove 28. The base 24 is divided into the base body 32 and the cover body 34. During the assembly process, the base body 32 and the cover body 34 can be placed on opposite sides of the protrusion 30 respectively, and the base body 32 and the cover body 34 can clamp the protrusion 30, and then the base body 32 and the cover body 34 are fixed, and the base 24 can be rotatably installed on the back plate 18, which is convenient for assembly.

The relative positions of the seat body 32 and the cover body 34 are not limited. For example, the seat body 32 may be located between the cover body and the accommodating cavity 16 , or the cover body 34 may be located between the seat body 32 and the accommodating cavity 16 .

There is a gap between the seat body 32 and the cover body 34 in the axial direction of the mounting hole 22, which may mean that the entire seat body 32 and the entire cover body 34 are spaced apart in the axial direction of the mounting hole 22, or that the seat body 32 and the cover body 34 are partially connected together and partially spaced apart.

The specific fixing method between the base body 32 and the cover body 34 is not limited, such as snap fixing, welding fixing, riveting fixing, screw fixing, etc.

As shown in Figures 7 and 10 to 13, in one embodiment, the base body 32 and the cover body 34 are fixed by snapping, and the cover body 34 includes a cover body 35 and an elastic snap member 36 arranged on the cover body 35. The base body 32 is provided with a snap hole 38 that cooperates with the elastic snap member 36. The cover body 34 and the base body 32 are snap-fitted through the elastic snap member 36 and the snap hole 38.

The elastic fastener 36 includes two elastic arms 40 respectively connected to the cover body 35, and the two elastic arms 40 are respectively provided with a slot 41 on the opposite sides. The two elastic arms 40 pass through the buckle hole 38 and insert the side parts of the seat body 32 located on the opposite sides of the buckle hole 38 into the corresponding slots 41. During the assembly process, the two elastic arms 40 can be brought close to each other first, and after the two elastic arms 40 pass through the buckle hole 38, the two elastic arms 40 are released, and the two elastic arms 40 will move away from each other under the action of their own elastic force, so that the seat body 32 is inserted into the slot 41 of the elastic arm 40. At this time, the seat body 32 can form a limiting effect on the cover body 34 in the axial direction of the mounting hole 22, so that the seat body 32 and the cover body 34 are relatively fixed in the axial direction of the mounting hole 22. At the same time, the elastic arms 40 will tightly press against the seat body 32 under the action of their own elastic force, so that the seat body 32 and the cover body 34 are also relatively fixed in the circumferential direction of the mounting hole 22.

The seat body 32 includes a seat body 42 and a buckle part 43 provided on the seat body 42, the buckle part 43 includes an extension part 44 extending from the seat body 42 toward the cover body 34 and a connection part 45 provided on the side of the extension part 44 close to the cover body 34, the connection part 45 and the seat body 42 are spaced apart in the axial direction of the mounting hole 22, the buckle hole 38 is provided through the connection part 45, and the connection part 45 is respectively inserted into the slots 41 of the two elastic arms 40 at the sides of the buckle hole 38 on the opposite sides, so that the seat body 42 and the cover body 35 are spaced apart to form a groove 28. Since the connection part 45 and the seat body 42 are spaced apart from each other in the axial direction of the mounting hole 22, after the seat body 32 and the cover body 34 complete the buckle fit, that is, the connection part 45 is inserted into the slot 41, the seat body 42 and the cover body 35 will be automatically spaced apart, so that the groove 28 is formed while the assembly is completed.

The seat body 42 is provided with a receiving groove 421, and two extensions 44 extend from two opposite inner walls of the receiving groove 421 toward the cover body 34 and protrude from the receiving groove 421, and the connecting portion 45 is connected between the two extensions 44. The receiving groove 421 is provided on the seat body 42, and after the seat body 32 and the cover body 34 are buckled, part of the elastic arm 40 will be received in the receiving groove 421, which enhances the compactness of the overall structure and reduces the overall volume.

The buckle hole 38 extends to the outer surface of the connecting portion 45 in the radial direction of the mounting hole 22 , so that during the assembly process, the two elastic arms 40 can be brought close to each other and then inserted into the buckle hole 38 from one radial side of the seat body 32 .

The specific number of the elastic snap members 36 and the snap-fitting portions 43 is not limited. In the present embodiment, there are multiple elastic snap members 36 and snap-fitting portions 43, which correspond one to one. The multiple elastic snap members 36 and the multiple snap-fitting portions 43 are evenly arranged at circumferential intervals along the mounting hole 22.

The cover body 35 and the elastic fastener 36 as well as the seat body 42 and the buckle part 43 can be assembled separately or integrally formed by injection molding or stamping. In this embodiment, the cover body 35 and the elastic fastener 36 are integrally formed, and the seat body 42 and the buckle part 43 are integrally formed to ensure the overall strength of the seat body 32 and the cover body 34, while eliminating the assembly process.

As shown in FIG. 14 , in another embodiment, the seat body 32 includes a seat body 42 and a protrusion 46 extending from the seat body 42 toward the cover body 34, the cover body 34 is provided with an insertion hole 48, a step 50 is provided on the side of the protrusion 46 away from the seat body 32, the protrusion 46 is inserted into the insertion hole 48 and is welded and fixed to the cover body 34, and the step 50 abuts against the side of the cover body 34 close to the seat body 32, so that the cover body 34 and the seat body 42 are spaced to form the groove 28. The protrusion 46 includes a first protrusion 52 and a second protrusion 54, the first protrusion 52 is fixedly connected to the seat body 42, the second protrusion 54 is fixed to the side of the first protrusion 52 away from the seat body 42, and the size of the first protrusion 52 is larger than the size of the second protrusion 54, so that the protrusion 46 is in a "convex" shape as a whole, thereby forming two steps 50 on the protrusion 46. The second protrusion 54 is inserted into the insertion hole 48 and welded to the cover body 34 , and the first protrusion 52 abuts against the side of the cover body 34 close to the seat body 32 , thereby supporting the cover body 34 , separating the seat body 42 and the cover body 34 , thereby forming a groove 28 .

The specific number of the protrusions 46 and the sockets 48 is not limited, and can be one or more. In the present embodiment, the number of the protrusions 46 and the sockets 48 are both multiple and correspond one to one, and each protrusion 46 is inserted into a corresponding socket 48.

The protrusion 46 and the seat body 42 can be assembled separately, or can be integrally formed by injection molding or stamping, etc. In this embodiment, the protrusion 46 and the seat body 42 are integrally formed, which saves assembly process while ensuring overall strength.

As shown in FIG. 15 , in another embodiment, threaded holes 56 are respectively provided on the base body 32 and the cover body 34, and screws 58 are passed through the threaded holes 56 on the base body 32 and the cover body 34. Both ends of the screw 58 are threadedly fixed to the base body 32 and the cover body 34 through corresponding threaded holes 56, and the base body 32 and the cover body 34 are spaced apart from each other to form a groove 28.

As shown in FIG. 16 , in yet another embodiment, rivet holes 60 are respectively provided on the base body 32 and the cover body 34 , and rivets 62 are passed through the rivet holes 60 on the base body 32 and the cover body 34 . Both ends of the rivet 62 are riveted and fixed to the base body 32 and the cover body 34 through corresponding rivet holes 60 , and the base body 32 and the cover body 34 are spaced apart from each other to form a groove 28 .

As shown in Fig. 8, Fig. 9 and Fig. 17, in one embodiment, the base 24 further includes a reinforcing member 64, the supporting member 26, the seat body 32 and the cover body 34 are all annular, the supporting member 26, the seat body 32 and the cover body 34 are all surrounded by the outer periphery of the reinforcing member 64, and the seat body 32 and/or the cover body 34 are fixedly connected to the reinforcing member 64. The reinforcing member 64 can enhance the overall strength of the bracket 14, reduce the risk of deformation of the bracket 14, and thus enhance the support stability of the bracket 14.

The specific fixing method of the seat body 32 and/or the cover body 34 and the reinforcement member 64 is not limited, for example, they are fixed by riveting, welding, or a limiting structure.

In one embodiment, one end of the support member 26 is rotatably connected to the base 24, and the other end is provided with a hand grip 66 connected to the mounting hole 22. When the support member 26 needs to be rotated out of the mounting hole 22, a finger can be inserted into the hand grip 66 and pressed against the support member 26, so that the support member 26 can be easily rotated out of the mounting hole 22.

The bracket 14 also includes a first fixed seat 68 and a second fixed seat 70, one of which is fixedly connected to the base 24, and the other is fixedly connected to the support member 26. The first fixed seat 68 and the second fixed seat 70 are rotatably matched through the rotating shaft 72, thereby realizing the rotatable matching of the support member 26 and the base 24, so that the support member 26 can rotate around the rotating shaft 72 relative to the base 24.

The first fixing seat 68 is provided with a notch 74, and the second fixing seat 70 is provided with a limiting boss 76 that matches the notch 74. Specifically, the first fixing seat 68 is fixedly connected to the support member 26, and the second fixing seat 70 is fixedly connected to the base 24. When the support member 26 rotates relative to the base 24, it will drive the first fixing seat 68 to rotate relative to the second fixing seat 70. When the limiting boss 76 enters the notch 74 and abuts against the first fixing seat 68, the first fixing seat 68 can no longer continue to rotate relative to the second fixing seat 70 in this direction, that is, the support member 26 can no longer rotate in this direction, which plays a limiting effect, limits the rotation angle of the support member 26, and avoids the problem that the support member 26 rotates too much and causes its support stability to deteriorate.

There is no limitation on the fixing method between the first fixing seat 68 and the support member 26 and the second fixing seat 70 and the base 24, such as riveting, welding, etc., and the first fixing seat 68 and the support member 26, the second fixing seat 70 and the base 24 can be integrally formed or assembled separately.

The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
