Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0030] like Figures 1 to 3 As shown, an embodiment of the present application provides a protective cover 1, which includes a protective cover body 10 and a support frame 20, has a support function, and can flexibly adjust the support angle according to the usage occasion, so as to better meet the user's usage needs.

[0031] The protective cover body 10 has an inner cavity surface 11 and a back side surface 12 that are arranged opposite to each other. The inner cavity surface 11 is located in the inner cavity of the protective cover body 10, and is suitable for being fitted with smart terminals such as mobile phones and tablet computers, so that the smart terminals can be reliably embedded and retained in the inner cavity. The back side surface 12 is located outside the inner cavity of the protective cover body 10, specifically on the side of the protective cover body 10 away from the inner cavity surface 11, and a first positioning portion 14 is provided on the back side surface 12. The material of the protective cover body 10 can be determined according to actual needs, and can be, for example, a plastic shell, a metal shell, etc., which is not limited in the embodiments of the present application.

[0032] The support frame 20 has a hinge end 21 and a support end 22 that are arranged opposite to each other. The hinge end 21 is hinged on the back side 12 of the protective cover body 10, and a second positioning portion 211 is provided on the hinge end 21. Here, the support frame 20 can be rotated around the hinge end 21 to be unfolded or folded so that the support end 22 is close to or away from the back side 12 of the protective cover body 10. The material of the support frame 20 can be determined according to actual needs, and can be, for example, a plastic frame, a metal frame, etc., which is not limited in the embodiment of the present application.

[0033] In the folded state, the support end 22 is folded to the back side 12 of the protective cover body 10, which is convenient for the user to use it by hand or carry it with the screen off. In the supported state, the support end 22 and the back side 12 of the protective cover body 10 remain separated, and the support end 22 and the bottom of the protective cover body 10 are supported on the desktop respectively; here, according to the surface morphology of the desktop in the use occasion or the viewing angle required by the user, the support frame 20 can be rotated around the hinge end 21 to the target position, so that the angle between the support end 22 and the back side 12 of the protective cover body 10 is adjusted to the required support angle, so that the protective cover 1 can be reliably supported and maintained on the desktop and provide the user with the required viewing angle; and after the support frame 20 is rotated to the target position, the first positioning portion 14 and the second positioning portion 211 are positioned and matched to keep the support frame 20 at the target position. Compared with the related art, the protective cover 1 provided in the embodiment of the present application has a bracket function, and can flexibly adjust the support angle according to the use occasion, so as to better meet the user's use needs.

[0034] The structures of the first positioning portion 14 and the second positioning portion 211 can be determined according to actual needs, and can adopt structures such as snap-fit ​​positioning, convex teeth and rack meshing positioning, etc., which are not limited in the present embodiment. Figures 1 to 7 As shown, in some embodiments, the first positioning portion 14 may be a positioning protrusion; the second positioning portion 211 may include a plurality of positioning slot sub-portions 2111 , and the plurality of positioning slot sub-portions 2111 are sequentially arranged along the rotation direction of the support frame 20 .

[0035] When the support frame 20 rotates around the hinge end 21, the positioning protrusion is sequentially inserted into the multiple positioning slot sub-sections 2111; specifically, when the driving force applied to the support frame 20 is greater than the positioning force between the positioning slot sub-section 2111 and the positioning protrusion, the support frame 20 can drive the multiple positioning slot sub-sections 2111 to rotate synchronously, so that the positioning slot sub-section 2111 corresponding to the positioning protrusion rotates and switches; accordingly, the positioning protrusion can be separated from the current positioning slot sub-section 2111, and then pass over the raised area between two adjacent positioning slot sub-sections 2111 and insert into the next positioning slot sub-section 2111. After the support frame 20 is rotated and adjusted to the target position, the positioning protrusion is inserted into the positioning slot sub-section 2111 corresponding to the target position; since the external driving force has been removed at this time, the positioning protrusion and the positioning slot sub-section 2111 can be used to keep the support frame 20 at the target position. Through the above arrangement, the protective cover 1 can have multiple deployment angles, and correspondingly provide the required multiple support angles, thus better meeting the use requirements.

[0036] In some embodiments, an elastic limiting portion 13 may be provided on the protective cover body 10. The elastic limiting portion 13 may protrude toward the side of the dorsal side surface 12 away from the inner cavity surface 11, and the first positioning portion 14 may be provided on the side of the protruding top 131 of the elastic limiting portion 13 facing the support frame 20. In this way, when the protective cover body 10 and the hinged end 21 are hinged, the elastic limiting portion 13 protruding backwards can make the first positioning portion 14 and the second positioning portion 211 fit closely; and under the positioning cooperation of the first positioning portion 14 and the second positioning portion 211, the second positioning portion 211 applies a positioning force to the first positioning portion 14 in the direction from the dorsal side surface 12 to the inner cavity surface 11, so that the elastic limiting portion 13 has a tendency to elastically deform toward the side where the inner cavity surface 11 is located, and the elastic limiting portion 13 further generates and applies an elastic force close to the second positioning portion 211 to the first positioning portion 14, so that the first positioning portion 14 and the second positioning portion 211 form a more closely positioned cooperation.

[0037] In some examples, the protective cover body 10 may be provided with two first hollow portions 15 extending therethrough, the first hollow portions 15 extending from the back side surface 12 to the inner cavity surface 11. The elastic limiting portion 13 is disposed between the two first hollow portions 15 so that the two first hollow portions 15 are spaced apart.

[0038] The structural relationship of the elastic limiting portion 13 on the protective cover body 10 can be determined according to actual needs, and can adopt types such as an integrally formed structural relationship and a split assembly structural relationship, which is not limited in the embodiments of the present application. Exemplarily, the elastic limiting portion 13 and the protective cover body 10 can be integrally formed, for example, the two can be integrally injection molded; here, the thickness of the elastic limiting portion 13 can be less than the thickness of the area surrounding the elastic limiting portion 13 on the protective cover body 10, so as to better ensure the elastic deformation performance of the elastic limiting portion 13. Another exemplary embodiment, the elastic limiting portion 13 and the protective cover body 10 can be manufactured separately and then assembled; here, the elastic limiting portion 13 can be a type of shrapnel such as a metal shrapnel, a plastic shrapnel, etc., and the two ends of the shrapnel are respectively arranged on the protective cover body 10 to separate the above-mentioned two first hollow portions 15.

[0039] In some examples, the side of the raised top 131 close to the inner cavity surface 11 can form an inner top, and the side of the raised top 131 facing the support frame 20 can form an outer top. Here, the first positioning portion 14 can be arranged on the outer top, and the distance between the inner top and the inner cavity surface 11 is greater than the clamping depth between the positioning protrusion and the positioning slot sub-portion 2111. By setting as above, the space for the elastic limiting portion 13 to elastically deform toward the side where the inner cavity surface 11 is located can be better guaranteed, so that the elastic limiting portion 13 is fully elastically deformed and the first positioning portion 14 is closely abutted against the second positioning portion 211, so that the first positioning portion 14 and the second positioning portion 211 form a reliable positioning match.

[0040] In some embodiments, the protective cover 1 may further include a support base 30. The support base 30 is disposed on the back side 12 of the protective cover body 10, and the support frame 20 can be rotatably embedded in or detached from the support base 30 around the hinge end 21, and the hinge end 21 passes through the support base 30 and is hinged to the back side 12 of the protective cover body 10. By providing the support base 30, when the protective cover 1 is not needed to provide a support function, the support frame 20 can be stored on the support base 30, so that the protective cover 1 has a relatively compact and small folding structure.

[0041] In some examples, the support base 30 may be provided with a receiving groove 31, which is opened on a side surface of the support base 30 away from the protective cover body 10, and the support frame 20 can be rotated around the hinge end 21 to be embedded in or out of the receiving groove 31. Here, the shape of the receiving groove 31 can match the support frame 20 so that the support frame 20 can be tightly stored.

[0042] For example, the support base 30 may be provided with a second hollow portion 32 that passes through the support base 30. The second hollow portion 32 is provided on the bottom surface of the receiving groove portion 31, and the second hollow portion 32 extends to the inner cavity surface 11, and the hinge end 21 passes through the second hollow portion 32 and is hinged to the back side surface 12 of the protective cover body 10. By the above arrangement, a compact and small assembly structure can be formed between the protective cover body 10, the support frame 20 and the support base 30.

[0043] In some examples, the engagement depth between the positioning protrusion and the positioning slot sub-portion 2111 may be greater than the matching clearance between the hinge end 21 and the bracket base 30. By setting as above, the positioning protrusion and the positioning slot sub-portion 2111 can form a tight and reliable positioning fit, avoiding the positioning fit failure caused by the excessive matching clearance between the hinge end 21 and the bracket base 30.
