Description

Technical Field

[0001] This application relates to the field of mobile phone technology, and in particular to a protective case for a mobile phone and a mobile phone kit having the same. Background Technology

[0002] To protect the components of a mobile phone from damage when it is subjected to inertial events such as drops, a detachable protective case can be installed on the phone.

[0003] Protective cases with rotating legs have appeared on the market. These legs can be selectively rotated to either a closed or supported position depending on the user's needs. In the closed position, the legs are folded into the protective case for easy carrying and gripping. In the supported position, the legs form an angle with the mobile phone, allowing the phone to be tilted and supported on a table, enabling the user to view and operate the phone without holding it. However, traditional protective cases with rotating legs typically have one of these drawbacks: 1) The legs are not detachably connected to the protective case body, making it impossible to replace damaged legs; 2) Even if some protective cases have legs that can be detached from and inserted into the protective case body, detachment and insertion are difficult; 3) Special positioning structures are required on both the legs and the protective case body to hold the legs in the closed and supported positions, which increases design complexity and manufacturing costs. Summary of the Invention

[0004] In order to solve at least one of the above-mentioned technical problems, this application provides a protective case for a mobile phone and a mobile phone kit having the same.

[0005] In a first aspect, a protective case for a mobile phone is provided, the mobile phone having a rear surface facing away from the user and a protrusion protruding from the rear surface to support a camera module, the protective case comprising:

[0006] The bottom wall has a first inner surface covering the rear surface, a first outer surface opposite to the first inner surface, a first through hole penetrating the first inner surface and the first outer surface to receive the protrusion, and a convex ring protruding from the first outer surface and extending around the first through hole in its entire circumference.

[0007] The leg is rotatably connected to the bottom wall and has a closed position and a supported position based on the rotation; in the supported position, the leg forms an angle with the bottom wall to support the mobile phone;

[0008] The outrigger is held in the supported position by abutting against the peripheral surface of the convex ring.

[0009] In some possible implementations, the top surface of the convex ring is coplanar with the top surface of the protrusion, or the top surface of the convex ring is slightly higher than the top surface of the protrusion.

[0010] In some possible implementations, it also includes:

[0011] The hollow portion extends through the first inner surface and the first outer surface and is continuous with the first through hole; an opening is formed at the junction of the hollow portion and the first through hole.

[0012] A slot is disposed at the opening and is formed by recessing from the inner wall of the first through hole into the bottom wall;

[0013] The rotating shaft engages with the slot by moving along the concave direction of the slot;

[0014] The support leg has a shape complementary to the hollow portion and is rotatably connected to the bottom wall via the pivot; in the closed position, the support leg fills the hollow portion.

[0015] Secondly, a protective case for a mobile phone is proposed, the mobile phone having a rear surface facing away from the user and a protrusion protruding from the rear surface to support a camera module, the protective case comprising:

[0016] The bottom wall has a first inner surface covering the rear surface, a first outer surface opposite to the first inner surface, and a first through-hole penetrating the first inner surface and the first outer surface to receive the protrusion.

[0017] The leg is rotatably connected to the bottom wall and has a closed position and a supported position based on the rotation; in the supported position, the leg forms an angle with the bottom wall to support the mobile phone;

[0018] The outrigger is held in the supported position by abutting against the peripheral surface of the protrusion.

[0019] In some possible implementations, it also includes:

[0020] The hollow portion extends through the first inner surface and the first outer surface and is continuous with the first through hole; an opening is formed at the junction of the hollow portion and the first through hole.

[0021] A slot is disposed at the opening and is formed by recessing from the inner wall of the first through hole into the bottom wall;

[0022] The rotating shaft engages with the slot by moving along the concave direction of the slot;

[0023] The leg has a shape complementary to the hollow portion and is rotatably connected to the bottom wall via the pivot; in the closed position, the leg fills the hollow portion and defines a portion of the inner wall surface of the first through hole.

[0024] In some possible implementations, the leg has a head end that connects to the pivot, the head end having an arcuate surface surrounding the pivot.

[0025] Thirdly, a protective case for a mobile phone is proposed, the mobile phone having a rear surface facing away from the user, a side surface connected to the rear surface, and buttons protruding from the side surface, the protective case comprising:

[0026] The bottom wall is configured to cover the rear surface;

[0027] A sidewall, extending from the periphery of the bottom wall, is configured to cover the side surface;

[0028] The open space has a first portion that extends through the bottom wall and a second portion that extends through the side wall and is continuous with the first portion;

[0029] The support leg, which is complementary in shape to the hollowed-out portion and has a third through hole, is rotatably connected to the bottom wall and has a closed position and a supported position based on the rotation;

[0030] In the closed position, the support leg fills the hollow portion, and the button extends into the third through hole to prevent the support leg from leaving the closed position; in the supported position, the support leg leaves the hollow portion and forms a certain angle with the bottom wall to support the mobile phone.

[0031] In some possible implementations, the side surface includes a length side surface extending in the longitudinal direction of the mobile phone, and the button protrudes from the length side surface;

[0032] The outrigger is connected to the bottom wall in a manner that allows it to rotate about the length direction.

[0033] In some possible implementations, the sidewall is closed at the end of the second portion.

[0034] Fourthly, a mobile phone kit is proposed, characterized in that it includes:

[0035] The protective shell as described in the first, second, or third aspect, and

[0036] The mobile phone.

[0037] According to the mobile phone protective case provided in this application, during use, the rotatable legs are held in a supported position by abutting against the peripheral surface of the mobile phone protrusion or by abutting against the peripheral surface of the closed protrusion ring used to protect the mobile phone protrusion. This reduces or even eliminates the need for a dedicated structure on the protective case for positioning the leg angle, thereby simplifying the construction of the protective case and improving cost-effectiveness.

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0075] In the description of this application and the claims, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.

[0076] To clearly describe this technology, before introducing the protective shell 200, we will first introduce the compatible devices such as... Figure 1 The mobile phone 100 shown has a front surface S1 facing the user, a rear surface S2 facing away from the user, a side surface S3 connecting the front surface S1 and the rear surface S2, a protrusion 1 protruding from the rear surface S2, a button 2 protruding from the side surface S3, an electrical connection socket 4 recessed from the side surface S3, and a camera module 3 for capturing images, wherein the camera module 3 is carried in the protrusion 1. The side surface S3 is located at the periphery of the mobile phone 100.

[0077] Button 2 can be a button 2 for user control of screen off and screen on, or a button 2 for controlling volume, etc., and the button 2 is configured such that: when pressed, it moves toward the interior of the mobile phone 100, so that the protrusion 1 of button 2 relative to the side surface S3 disappears, that is, it no longer protrudes from the side surface S3 of the mobile phone 100; when the pressing of button 2 is released, it moves away from the interior of the mobile phone 100, so that it protrudes from the side surface S3 of the mobile phone 100 again.

[0078] Electrical connection port 4 is a connector for connecting power lines or signal lines, such as a Type-C connector. By inserting the end plug of the power line or signal line into electrical connection port 4, power or signals can be transmitted between an external device and the mobile phone 100.

[0079] The side surface S3 of the mobile phone 100 includes two length side surfaces extending in the length direction D1, namely the left side surface and the right side surface, and two width side surfaces extending in the width direction D2, namely the top side surface and the bottom side surface. The aforementioned button 2 is specifically disposed on the right side surface, that is, the button 2 protrudes from the right side surface of the mobile phone 100, while the electrical connection port 4 is specifically disposed on the bottom side surface, that is, the electrical connection port 4 is recessed from the bottom side surface.

[0080] The camera module 3 provides the mobile phone 100 with a shooting function. Due to the need for a slim and lightweight design of the mobile phone 100, the thickness space of the mobile phone 100 is limited. In order to reliably arrange the high-definition camera module 3 with specified performance, a protrusion 1 is formed on the rear surface S2 of the mobile phone 100. This protrusion 1 provides additional mounting space for the high-definition camera module 3 in the thickness direction D3. The protrusion 1 can be integrally formed with the rear wall of the mobile phone 100; more specifically, the two can be formed from the same piece of high-strength glass. In this embodiment, the protrusion 1 is formed as a square with rounded corners and is located at the middle position in the width direction D2 and the upper side in the length direction D1 of the rear wall. Of course, the protrusion 1 can also be formed as a circle, rectangle, or triangle.

[0081] Next, please see Figures 2 to 8 and combined Figure 1 This application introduces a protective shell 200 provided in the first embodiment, which includes a bottom wall 5, a side wall 6, a hollow part 7, a slot 8, a pivot 10, and a support leg 9.

[0082] The bottom wall 5 has a first inner surface S4 covering the aforementioned rear surface S2, a first outer surface S5 opposite to the first inner surface S4, and a first through hole 5a penetrating the first inner surface S4 and the first outer surface S5 to receive the aforementioned protrusion 1. That is, the bottom wall 5 is used to cover the rear surface S2 of the mobile phone 100, and the first through hole 5a penetrates the bottom wall 5 in the thickness direction D3. In use, the protrusion 1 of the mobile phone 100 extends into the first through hole 5a, and the peripheral surface S8 of the protrusion 1 is in contact with the inner wall surface of the first through hole 5a. In addition, since the movable rear surface S2 is a flat surface, the first inner surface S4 is also formed as a flat surface to match it, and for the sake of appearance, feel, and manufacturing cost, the first outer surface S5 is also formed as a flat surface.

[0083] The sidewall 6 extends substantially perpendicularly from the periphery of the bottom wall 5, and has a second inner surface S6 covering the aforementioned side surface S3 and a second outer surface S7 opposite to the second inner surface S6. Furthermore, the sidewall 6 and the bottom wall 5 are an integral structure. In this embodiment, the sidewall 6 and the bottom wall 5 are integrally molded from a resin with sufficient structural strength. In other embodiments, the sidewall 6 and the bottom wall 5 of the protective shell 200 may also be formed from a flexible metallic material.

[0084] The side wall 6 has a through second through hole 6b. When the protective case 200 is installed on the mobile phone 100, the second through hole 6b receives the aforementioned key 2 of the mobile phone, so that the key 2 can be used normally even when the mobile phone 100 is equipped with the protective case 200.

[0085] The cutout 7 has a first portion 7a formed on the bottom wall 5 and a second portion 7b formed on the side wall 6. The first portion 7a penetrates the first inner surface S4 and the first outer surface S5 and is continuous with the first through hole 5a. The second portion 7b penetrates the second inner surface S6 and the second outer surface S7 and is continuous with the first portion 7a, extending to the electrical connection socket 4. That is, the cutout 7 also penetrates the side wall 6 of the protective shell 200. The first portion 7a is formed as an elongated strip extending in the length direction D1. The second portion 7b is slightly larger than the electrical connection socket 4 and completely surrounds the electrical connection socket 4 so that the plug of the power line or signal line can be inserted into the electrical connection socket 4. Furthermore, the side wall 6 is closed at the end of the second portion 7b (connected by a short strip 6a), thereby preventing the side wall 6 from deforming away from each other at the second portion 7b, thus maintaining the structural integrity of the protective shell 200. Furthermore, since the first part 7a of the open space is continuous with the first through hole 5a, an opening 11 is formed at the junction of the first part 7a and the first through hole 5a.

[0086] The outrigger 9 is rotatably mounted to the bottom wall 5 via the pivot 10.

[0087] Specifically, two slots 8 are respectively disposed on both sides of the opening 11 and are continuous with the opening 11, and the slots 8 are formed by recessing from the inner wall surface of the first through hole 5a into the bottom wall 5. In this embodiment, the slot 8 is formed with a narrow opening 8a and a wide bottom. Specifically, the slot 8 includes an opening 8a and a cavity 8b. The opening 8a is continuous with the inner wall surface of the first through hole 5a, and the cavity 8b is located downstream of the opening 8a along the recessed direction D4 of the slot 8, that is, the cavity 8b is located inside the opening 8a. The size of the opening 8a is smaller than the size of the cavity 8b. In addition, based on the symmetrical position and shape of the two slots 8, for simplicity, only one of the two slots 8 is shown in the figure. In some embodiments, the bottom wall portion at the location of the slot 8 can be thickened to facilitate the installation of the slot 8.

[0088] The pivot 10 has two end portions 10a that respectively engage with two slots 8, and a middle portion 10b connecting the two end portions 10a and located in the opening 11. Specifically, the cavity 8b of the slot 8 receives the end portions 10a of the pivot 10. Furthermore, the size of the opening 8a is smaller than the size of the end portion 10a. Therefore, under normal use, the end portion 10a of the pivot 10 is stably held in the slot 8 because it is blocked by the bottom wall 5 at the opening 8a, and based on this, the support leg 9 can be prevented from accidentally detaching from the protective shell 200. In addition, the pivot 10 can be made of metal.

[0089] The support leg 9 has a shape complementary to the hollow portion 7 and is connected to the middle portion 10b of the pivot 10 in a manner that allows it to rotate relative to the bottom wall 5 about the axis of the pivot 10, and has a closed position and a supported position based on this rotation. In this embodiment, the pivot 10 passes through the head end 9a1 of the support leg 9, and the pivot 10 is rotatable relative to the head end 9a1 of the support leg 9. In other embodiments, the pivot 10 and the head end 9a1 of the support leg 9 are fixedly joined together, and the two cannot rotate relative to each other.

[0090] More specifically, the support leg 9 has a first segment 9a that is complementary in shape to the first portion 7a of the cutout 7, and a second segment 9b that is complementary in shape to the second portion 7b of the cutout 7. In the closed position, the first segment 9a fills the entire second portion 7b and defines a portion of the inner wall surface of the first through hole 5a; the second segment 9b fills a portion of the second portion 7b, thereby defining, together with the remainder of the second portion 7b, a socket 13 that overlaps with the electrical connection socket 4, which provides a channel for the insertion of power lines or signal lines into the electrical connection socket 4. In the supported position, the support leg 9 is separated from the cutout 7 and forms an angle (e.g., 60° or 90°) with the bottom wall 5 of the protective housing 200, so that the mobile phone 100 is supported on the table in an inclined state by means of the extended support leg.

[0091] Furthermore, because the second segment 9b of the support leg 9 defines a portion of the wall of the socket 13 in the closed position, the user can easily apply a force to the support leg 9 away from the mobile phone 100 by inserting their fingertip into the socket, thus changing the support leg 9 from the closed position to the supported position. To ensure that the support leg 9 can be stably held in the closed position, such as... Figure 8 As shown, hemispherical protrusions can be provided on the support leg 9, particularly the second segment 9b of the support leg 9, and hemispherical recesses can be provided on the inner wall of the hollow portion 7, particularly the second part 7b of the hollow portion 7, to receive the aforementioned protrusions. Multiple sets of protrusions and recesses can be provided. For ease of drawing, the protrusions and recesses are omitted in other figures. Of course, other methods can also be used to maintain the position of the support leg 9 relative to the bottom wall 5; for example, the sides of the support leg 9 can be provided with a friction surface having a textured surface.

[0092] Furthermore, the end portion 10a of the rotating shaft 10 is engaged in the slot 8 by moving along the concave direction D4 of the slot 8. Specifically, the end portion 10a of the rotating shaft 10 is configured such that: by moving along the concave direction D4 of the slot 8, the bottom wall 5 at the opening 8a is pushed open to both sides, thereby entering the cavity 8b; after the end portion 10a enters the relatively spacious cavity 8b, the end portion 10a is held in the cavity 8b based on the deformation of the bottom wall 5 at the opening 8a; and by moving along the opposite direction D5 of the concave direction, the bottom wall 5 at the opening 8a is pushed open to both sides, thereby exiting the cavity 8b via the opening 8a. In this way, the operator can grasp the support leg 9 with the rotating shaft 10, and with the two end portions 10a of the rotating shaft 10 aligned with the slots 8a of the two retaining grooves 8, apply a downward force to the support leg 9. This causes the end portions 10a of the rotating shaft 10 to push open the bottom wall 5 at the slot 8a, thus entering the cavity 8b and completing the installation of the support leg 9 with the bottom wall 5. Alternatively, after the support leg 9 is installed with the bottom wall 5, by inserting a fingertip into the insertion port and applying force to the support leg 9, the support leg 9 is disengaged from the closed position. Then, by grasping the support leg 9 and applying an upward force, the rotating shaft 10 moves towards the slot 8a under the drive of the support leg 9, and pushes open the bottom wall 5 at the slot 8a with a certain degree of deformation, thus disengaging from the retaining groove 8. In this way, the support leg 9 can be detached from the protective shell 200. As a result, if the support leg 9 is damaged, a new support leg 9 can be easily replaced. Therefore, the protective case 200 can include multiple legs 9 in its factory packaging, but only one set of components other than the legs 9 is provided, because the frequently used legs 9 are more prone to damage than other components. Furthermore, the protective case 200 and the mobile phone 100 can be packaged together in the same package and sold as a complete mobile phone 100 kit (or mobile phone kit 1000). In addition, compared to assembling the legs 9 to the protective case 200 in a non-removable manner, the design of this embodiment helps to reduce the manufacturing difficulty and cost of the protective case 200.

[0093] In this embodiment, the support leg 9 is held in the aforementioned support position by the peripheral surface S8 of the protrusion 1 abutting against the extended support leg 9, thereby preventing the support leg 9 from rotating further away from the hollowed-out portion 7, so that the support leg 9 and the bottom wall 5 maintain the aforementioned certain angle, that is, the support leg 9 is held in the support position. In this way, this embodiment cleverly utilizes the protrusion 1 of the mobile phone 100 itself to abut against the extended support leg 9, so that the support leg 9 can be stably held in the support position (support angle), thereby reducing or even eliminating the structure on the protective case 200 specifically used to position the angle of the support leg 9, thereby simplifying the construction of the protective case 200 and thereby improving cost efficiency.

[0094] The head end 9a1 of the support leg 9 has an arc surface S9 around the pivot 10. In this way, during the rotation of the support leg 9 from the closed position to the supported position, interference between the head end 9a1 and the peripheral surface S8 of the protrusion 1 can be prevented, which would prevent the support leg 9 from continuing to rotate before reaching the supported position.

[0095] Furthermore, since the card slot 8 is formed by recessing into the inner wall surface of the first through hole 5a, when the protective case 200 is assembled onto the mobile phone 100, the protrusion 1 of the mobile phone 100 will cover the slot opening 8a of the card slot 8, thereby restricting the end portion 10a of the rotating shaft 10 within the card slot 8 and preventing it from coming out. Thus, under the use of the protective case 200, the support leg 9 is further prevented from accidentally coming off the protective case 200.

[0096] Next, please see Figures 9 to 12 , Figures 9 to 12 A protective case 200 for a mobile phone 100 according to a second embodiment of this application is shown, which has a similar structure to the protective case 200 of the first embodiment. It can be understood with reference to the description of the first embodiment. For simplicity, identical or similar components are given the same or similar reference numerals, and repetitive detailed descriptions of their identical parts are omitted. The differences between this embodiment and the first embodiment are described below.

[0097] In this embodiment, the bottom wall 5 has a protruding ring 12, which integrally protrudes from the first outer surface S5 and surrounds the first through hole 5a, extending from one side of the opening 11 to the other side of the opening 11. The protruding ring 12 defines a portion of the inner wall surface of the first through hole 5a, and two slots 8 are respectively disposed at the two ends of the protruding ring 12. With this design, without having to thicken the bottom wall 5 of the protective shell 200 as a whole, the protruding portion 1 extending beyond the first through hole 5a in the first embodiment can be covered circumferentially by the protruding ring 12, reducing the possibility of damage to the protruding portion 1; more advantageously, without having to thicken the bottom wall 5 of the protective shell 200 as a whole, the slots 8 can be easily machined, because the protruding ring 12 provides sufficient thickness space for the machining of the slots 8.

[0098] In this embodiment, when the protective case 200 is assembled onto the mobile phone 100, the top surface of the convex ring 12 is coplanar with and adjacent to the top surface of the protrusion 1. In other embodiments, the top surface of the convex ring 12 may be slightly higher than the top surface of the protrusion 1 to better protect the camera module 3 at the protrusion 1.

[0099] The head end 9a1 of the support leg 9, which connects to the middle portion 10b of the pivot 10, is formed to be larger than in the first embodiment. In this embodiment, the head end 9a1 of the support leg 9 is formed to be thicker than the rest of the support leg 9, and the thickness of the head end 9a1 is substantially the same as the thickness of the bottom wall 5 at the protruding ring 12. In the closed position, the head end 9a1 of the support leg 9 fills the opening 11, and the top surface of the head end 9a1 is coplanar with the top surface of the protruding ring 12, thus ensuring the appearance of the protective shell 200 at the protruding ring 12.

[0100] Because of the thickened convex ring 12 and the thickened head end 9a1, the protective shell 200 has higher structural strength at the convex ring 12 and the head end 9a1 compared with the first embodiment. Therefore, the slot 8 and the rotating shaft 10 provided at this part have better positional stability.

[0101] Next, see Figure 13 , Figure 13 The illustration shows the state of the protective case 200 provided in the third embodiment of this application when it is installed on the mobile phone 100 (the legs 9 are in the closed position). It has a similar structure to the protective case 200 of the first and second embodiments, and can be understood with reference to the descriptions of the first and second embodiments. For simplicity, identical or similar components are given the same or similar reference numerals, and repetitive detailed descriptions of their identical parts are omitted. The following focuses on describing the differences between this embodiment and the first and second embodiments.

[0102] In the first and second embodiments, the support leg 9 extends along the length direction D1 of the mobile phone 100 and the protective case 200, and the pivot 10 extends along the width direction D2 of the mobile phone 100 and the protective case 200, thereby supporting the mobile phone 100 on the table in portrait mode. However, this embodiment is different. In this embodiment, the support leg 9 extends along the width direction D2 of the mobile phone 100 and the protective case 200, and the pivot 10 extends along the length direction D1 of the mobile phone 100 and the protective case 200, thereby supporting the mobile phone 100 on the table in landscape mode.

[0103] Furthermore, the second segment 9b of the support leg 9 has a third through hole 9b1. In the closed position, the aforementioned protruding button 2 of the mobile phone 100 extends into the third through hole 9b1, thereby preventing the support leg 9 from leaving the closed position by means of the button 2 blocking the inner surface of the third through hole 9b1. In this way, the button 2 of the mobile phone 100 itself is cleverly used to engage the support leg 9 in the closed position, so that the support leg 9 can be stably held in the closed position. This reduces or even eliminates the need for structures on the protective case 200 specifically used to position the support leg 9 (e.g., the aforementioned hemispherical protrusions and recesses), thereby simplifying the construction of the protective case 200 and improving cost-effectiveness.

[0104] The cross-sectional shape of the third through hole 9b1 corresponds to the button 2 of the mobile phone 100, and the cross-sectional size of the third through hole 9b1 can be equal to or slightly larger than that of the button 2. With this design, on the one hand, the form fit between the button 2 and the third through hole 9b1 can be better utilized to prevent the support leg 9 from leaving the closed position; on the other hand, it will not obstruct the pressing and return of the button 2.

[0105] Despite Figure 13 In this case, the second part of the cutout 7 is configured to penetrate the sidewall 6 in the thickness direction D2 of the mobile phone 100, thereby opening the sidewall 6 at the end of the second part, i.e., the end of the cutout 7. However, based on the foregoing description, it can be understood that the sidewall 6 of the protective shell 200 can also be closed at the end of the second part, for example, by using a similar Figure 5 The short strip 6a shown connects the sidewall 6 at the end of the hollowed-out part 7.

[0106] Next, see Figures 14 to 16 , Figures 14 to 16 This application illustrates a protective case 200 for a mobile phone 100 according to a fourth embodiment of the present application. This case has a structure similar to the protective cases 200 of the first, second, and third embodiments, and can be understood with reference to the descriptions of the first, second, and third embodiments. For simplicity, identical or similar components are given the same or similar reference numerals, and repetitive detailed descriptions of their identical parts are omitted. The following focuses on describing the differences between this embodiment and the first, second, and third embodiments.

[0107] In this embodiment, the protective shell 200 also has a raised ring 12. In the second and third embodiments, the raised ring 12 is a non-closed ring (open ring) extending from one side of the opening 11 to the other side of the opening 11. However, this embodiment is different. In this embodiment, the raised ring 12 is a closed ring extending along the entire circumference of the first through hole 5a. In this way, the bottom walls 5 on both sides of the first opening 11 are connected together by the closed raised ring 12 (more specifically, the connecting portion 12a of the raised ring 12 described later), thereby preventing the bottom walls 5 from deforming away from each other at the opening 11 and improving the structural integrity of the protective shell 200.

[0108] The closed convex ring 12 has a connecting portion 12a extending at the opening 11 to connect the two sides of the opening 11. When the support leg 9 rotates about the pivot 10 away from the cutout 7 to form a certain angle (e.g., 60° or 90°) relative to the bottom wall 5, the connecting portion 12a (more specifically, the peripheral surface of the convex ring 12 at the connecting portion 12a) abuts against the spread support leg 9, thereby preventing the support leg 9 from rotating further away from the cutout 7, so that the support leg 9 is held in the prescribed support position. Compared with the method of using the protrusion 1 to abut against the support leg 9 in the second embodiment, the use of the convex ring 12 to support the support angle of the support leg 9 in this embodiment can better prevent the protrusion 1 of the mobile phone 100 from being crushed.

[0109] In this fourth embodiment, the support leg 9 can be mounted onto the protective case 200 from the first inner surface S4 side of the bottom wall 5 when the protective case 200 is separated from the mobile phone 100.

[0110] This application also provides a method for using a mobile phone protective case. This method is applicable to the protective case 200 described in the first to third embodiments of the foregoing embodiments. Referring to the preceding pattern, the method includes:

[0111] When the pivot 10 and the support leg 9 are engaged with each other, the end portion 10a is moved along the recessed direction D4 of the slot 8 by moving the pivot 10 along the recessed direction D4, thereby causing the pivot 10 to be engaged in the slot 8.

[0112] With the first through hole 5a aligned with the protrusion 1, the protective shell 200 is assembled onto the mobile phone 100, thereby covering the slot 8a of the card slot 8 with the protrusion 1, so as to restrict the end portion 10a and thus the rotating shaft 10 within the card slot 8.

[0113] When it is necessary to remove the support leg 9 for replacement or maintenance, the end portion 10a is removed from the bottom wall 5 by moving the pivot 10 in the opposite direction D5 of the recessed direction of the slot 8, thereby removing the pivot 10 from the slot 8 and thus removing the support leg 9 from the bottom wall 5, while the protective case 200 is removed from the mobile phone 100.
