[0025] Before describing the embodiments in detail, it should be understood that the present invention is not limited to the detailed structure or component arrangement described below or in the accompanying drawings in this application. The present invention may be an embodiment implemented in other ways. Moreover, it should be understood that the words and terms used herein are for descriptive purposes only and should not be interpreted as limiting. The words "including", "comprising", "having" and similar words used herein are intended to include the matters listed thereafter, their equivalents and other additional matters. In particular, when describing "a certain element", the present invention does not limit the number of the element to one, but may also include multiple elements.

[0026] like Figure 1-5 As shown, the present invention provides a protective shell 10 with a supporting function that can achieve multi-angle and multi-directional support. The protective shell 10 includes a shell 12 and a bracket structure 14 rotatably connected to the shell 12. The shell 12 is used to install an electronic device to protect the electronic device. The electronic device is, for example, a mobile phone, a tablet computer, etc. In this embodiment, a mobile phone is used as an example for explanation, and the protective shell 10 is a mobile phone shell. Specifically, the shell 12 includes a back panel 16 and a side frame 18 connected to the periphery of the back panel 16. The back panel 16 and the side frame 18 together form a storage space for accommodating the mobile phone. The bracket structure 14 is connected to the back panel 16 and can be switched between a supporting state and a storage state by rotation. When the bracket structure 14 is in the supporting state, the bracket structure 14 is unfolded to support the shell 12 on a surface; when the bracket structure 14 is in the storage state, the bracket structure 14 is folded onto the back panel 16.

[0027] like Figure 5 and Figure 6 As shown, a through hole 20 is provided in the central region of the back plate 16. A damping member 22 is fixedly disposed outside the through hole 20, and a fixing member 24 is disposed inside the through hole. The fixing member 24 is fixedly connected to the support structure 14 so as to rotate along with the support structure 14 along the axial direction of the through hole 20, i.e., the thickness direction of the housing 12. The support structure 14 abuts against the outside of the damping member 22, and the damping member 22 is provided with one of a protrusion 26 and a groove 28 on the side opposite the support structure 14. The support structure 14 is provided with the other of the protrusion 26 and the groove 28 on the side opposite the damping member 22. The protrusion 26 engages with the groove 28 to limit the rotation of the support structure 14.

[0028] Further, see Figure 7A plurality of stop blocks 30 are spaced apart on the inner wall of the through hole 20, with stop positions 32 formed between adjacent stop blocks 30. The damping member 22 is annular, and the inner annular hole of the damping member 22 faces the through hole 20. The inner annular wall of the damping member 22 extends toward one side of the through hole 20 to form a plurality of stop pieces 34. The stop pieces 34 are spaced apart. During installation, each stop piece 34 is positioned within a corresponding stop position 32. The stop blocks 30 circumferentially limit the stop pieces 34 to restrict the rotation of the damping member 22. The bracket structure 14 then abuts against the damping member 22 to limit the damping member 22 in the axial direction, thereby fixing the damping member 22 relative to the housing 12.

[0029] like Figure 8 and Figure 9 As shown, in the illustrated embodiment, the protrusion 26 is provided on the side of the damping member 22 relative to the support structure 14, and the groove 28 is provided on the side of the support structure 14 relative to the damping member 22. A plurality of protrusions 26 may be provided, and are symmetrically arranged on the damping member 22 at even intervals along the circumferential direction. For example, a protrusion 26 is provided on both radially opposite sides of the damping member 22 in the length direction of the shell 12, and a protrusion 26 is provided on both radially opposite sides of the damping member in the width direction of the shell 12, so that the support structure 14 can support the shell 12 laterally or vertically.

[0030] When the protrusion 26 is located in the groove 28, it can limit the rotation of the support structure 14. When the applied rotational force is greater than a certain value, the protrusion 26 will be disengaged from the groove 28, and the support structure 14 can rotate relative to the shell 12. After rotating to a certain angle, the protrusion 26 will overlap with the groove 28 again and be engaged in the groove 28, playing a limiting role, preventing the support structure 14 from rotating relative to the shell 12 when it is not subjected to a certain value of rotational force, thereby ensuring the stable support of the support structure 14.

[0031] Preferably, a through hole 36 is provided on the damping member 22, and the through hole 36 extends from the inner wall on the radial inner side toward the hole to form an elastic arm 38. The protrusion 26 is arranged at the end position of the elastic arm 38, so that the protrusion 26 can undergo a certain amount of elastic deformation to facilitate the rotation of the support structure 14.

[0032] Furthermore, a gasket 40 is provided between the damping member 22 and the back plate 16. The gasket 40 is also annular. A first accommodating groove 42 is provided on the outer side of the back plate 16, outside the through hole 20. The gasket 40 is accommodated in the first accommodating groove 42, and the damping member 22 is abutted against the outer side of the gasket 40. A relief hole 44 is provided on the gasket 40 at a position corresponding to the through hole 36, and a relief position 45 is provided in the first accommodating groove 42 corresponding to the relief hole 44. With this arrangement, when the support structure 14 rotates relative to the housing 12, the sidewall of the groove 28 squeezes the protrusion 28, causing it to deviate toward the side away from the support structure 14. At the same time, the end of the elastic arm 38 is squeezed and tilted into the relief hole 44 and the relief position 45, reducing the rotational force applied to the support structure 14 to enable it to rotate relative to the housing 12, thereby facilitating the rotation of the support structure 14.

[0033] In the illustrated embodiment, the support structure 14 includes a support plate 46, a support rod 48, and a support seat 50. The support seat 50 is positioned against the outside of the damping member 22 and can rotate axially in the thickness direction of the housing 12 to adjust the support direction of the support structure 14. Grooves 28 are provided on the side of the support seat 50 opposite the damping member 22, and the number and position of the grooves 28 correspond to the protrusions 26. The support seat 50 is fixedly connected to the fixing member 24. Specifically, the fixing member 24 is circular, and its diameter is larger than the diameter of the through hole 20. A screw hole 52 is provided on the side of the support seat 50 opposite the damping member 22 in an area corresponding to the through hole 20. A fixing hole 54 is provided on the side of the fixing member 24 opposite the support seat 50 in an area corresponding to the through hole 20. The fixing member 24 and the support seat 50 are relatively fixed by screws passing through the fixing holes 54 and then threadedly connected to the screw holes 52 through the through hole 20. In other embodiments, the support seat 50 and the fixing member 24 may be fixed by other fixing methods.

[0034] Preferably, a second receiving groove 56 is defined on the inner side of the back plate 16 outside the through hole 20 , and the fixing member 24 is received in the second receiving groove 56 .

[0035] Furthermore, the shell 12 also includes a covering member 58, and a card slot 60 is provided on the inner side of the back plate 16 outside the second accommodating groove 56. The covering member 58 is inserted into the card slot 60 to ensure the overall aesthetics of the protective shell 10, and the outer surface of the covering member 58 is flush with the inner surface of the back plate 16 to avoid affecting the installation of the mobile phone.

[0036] Support rod 48 has opposing first and second ends 48a, 48b. First end 48a of support rod 48 is rotatably connected to support base 50, allowing support rod 48 to rotate relative to support base 50 along a first rotation axis. Second end 48b of support rod 48 is rotatably connected to support plate 46, allowing support plate 46 to rotate relative to support rod 48 along a second rotation axis. Preferably, the first rotation axis and the second rotation axis are parallel. The support structure 14 can be adjusted in terms of support mode and angle by virtue of the mutual rotation of support plate 46, support rod 48, and support base 50, so that the support structure 14 can be adjusted to a state suitable for the user.

[0037] The bracket seat 50 is rotatably connected to the back plate 16, so that the bracket seat 50 can be axially rotated in the thickness direction of the shell 12, which is also perpendicular to the back plate 16, to adjust the support direction of the bracket structure 14, thereby allowing the bracket structure 14 to support the shell 12 in multiple directions and angles, such as supporting the shell 12 horizontally or vertically. When the bracket structure 14 supports the shell 12 horizontally, the mobile phone installed in the shell 12 can be used in landscape mode, and the first rotation axis or the second rotation axis is parallel to the length direction of the shell 12; when the bracket structure 14 supports the shell 12 vertically, such as Figure 2 and 3 As shown, the mobile phone installed in the housing 12 can be used in portrait orientation, and at this time the first rotation axis or the second rotation axis is parallel to the width direction of the housing 12 .

[0038] More specifically, the bracket seat 50 is rotatably connected to the first end 48a of the support rod 48 via a first rotating shaft 62. Two first pivoting portions are spaced apart at the first end 48a of the support rod 48, each of which has an axial hole. A first rotating connection portion is provided at one end of the bracket seat 50, each of which has an axial hole. During installation, the first rotating connection portion is placed between the two first pivoting portions, and the first rotating shaft 62 is inserted through the axial hole of the first rotating connection portion, with its two ends respectively inserted into the axial holes of the two first pivoting portions, thereby achieving a rotatable connection between the bracket seat 50 and the support rod 48. Preferably, a damping sleeve 64 is sleeved on the first rotating shaft 62 to increase the frictional resistance of the support rod 48 to rotation relative to the bracket seat 50, so that when the support rod 48 rotates relative to the bracket seat 50, it can remain firmly in any rotational position.

[0039] The bracket plate 46 is rotatably connected to the second end 48b of the support rod 48 via a second rotating shaft 66. The second end 48b of the support rod 48 is provided with two second pivoting portions at intervals, and the second pivoting portions are provided with an axial hole. A connecting member 68 is provided at one end of the bracket plate 46. The connecting member 68 is fixed to the bracket plate 46 by, for example, bolts, and the connecting member 68 is provided with an axial hole. During installation, the connecting member 68 is placed between the two second pivoting portions, and the second rotating shaft 66 is passed through the axial hole of the connecting member, with its two ends respectively inserted into the axial holes of the two second pivoting portions, thereby achieving a rotatable connection between the bracket plate 46 and the support rod 48. Preferably, a damping shaft sleeve 64 is provided on the second rotating shaft 66 to increase the frictional resistance of the bracket plate 46 to the rotation relative to the support rod 48, so that when the bracket plate 46 rotates relative to the support rod 48, it can remain firmly in any rotation position.

[0040] In the illustrated embodiment, a receiving groove 70 is provided on the outer side of the back panel 16 outside the first receiving groove 42, and a side edge 72 is protruded from the periphery of the bracket plate 46. The side edge 72 forms an escape space for avoiding the bracket seat 50 and the support rod 48. When the support rod 48 and the bracket plate 46 are rotated and folded onto the bracket seat 50, the side edge 72 is accommodated in the receiving groove 70. For example, the side edge 40 can be fastened in the receiving groove 70 in a snap-fit manner. The bracket plate 46 completely covers the support rod 48 and the bracket seat 50, and the support rod 48 and the bracket seat 50 are accommodated in the escape space, so that the protective shell 10 is beautiful as a whole.

[0041] Preferably, when the support rod 48 and the bracket plate 46 are rotated and folded onto the bracket seat 50, the outer surface of the bracket plate 46 is flush with the outer surface of the back panel 16, avoiding affecting the user's feel and increasing the aesthetics of the protective case 10.

[0042] The support plate 46 has a first surface 46a and a second surface 46b opposite to each other, and the side edge 72 is located on the side of the second surface 46b. When the support structure 14 is in the supporting state, the support plate 46 can be rotated so that the first surface 46a faces downward, or the second surface 46b faces downward. When the first surface 46a faces downward, as shown in FIG. Figure 3 As shown, the support plate 46 protrudes in front of the support structure 14. At this time, when the support structure 14 vertically supports the shell 12, the bottom of the shell 12 can be placed on the support plate 46, making the support more stable; when the second surface 46b is facing downward, as shown in FIG. Figure 2 As shown, the support plate 46 protrudes from the rear of the support structure 14 .

[0043] Preferably, a lens 74 is further provided on the support structure 14. In this embodiment, the lens 74 is disposed within the clearance space enclosed by the side edges 72. The lens 74 is attached to the second surface 46b of the support plate 46, for example, by snapping. The user can rotate the support plate 46 so that the second surface 46b faces outward, exposing the lens 74 for use as a mirror, thereby enhancing the functionality of the protective case 10. In other embodiments, the lens 74 may also be disposed elsewhere on the support structure 14, such as on the support rod 48.

[0044] In summary, the present invention provides a protective shell with a supporting function, in which the bracket structure is rotatably connected to the back plate of the shell to achieve multi-angle and multi-directional support, so that the bracket can support the shell horizontally or vertically. The two ends of the support rod of the bracket structure are rotatably connected to the bracket plate and the fixing member respectively, and the support mode and support angle can be adjusted by rotation. A through hole is provided on the back plate, a fixing member is provided on the inner side of the through hole, and a damping member is provided on the outer side of the through hole. The fixing member is fixedly connected to the bracket seat to rotate with the bracket seat. A protrusion is provided on one of the sides of the damping member relative to the bracket seat and the side of the bracket seat relative to the damping member, and a groove is provided on the other side. When the protrusion is located in the groove, it can limit the rotation of the bracket structure. When the applied rotational force is greater than a certain value, the bracket structure can rotate relative to the shell. After rotating a certain angle, the protrusion is embedded in the groove to play a limiting role. The protective shell with a supporting function of the present invention has a simple structure, novel style, convenient and stable operation, can achieve multi-angle and multi-directional support, brings convenience to users, and is suitable for promotion and application.
