Description

Technical Field

[0001] This application relates to the technical field of mobile phones, and particularly to a mobile phone protective case, its usage method, and a mobile phone set. Background Art

[0002] In order to prevent relevant components of a mobile phone (also known as a cell phone) from being damaged when the mobile phone undergoes inertial events such as dropping, a detachable protective case can be installed on the mobile phone.

[0003] There have already appeared protective cases with legs on the market, and the leg case can be selectively rotated to a closed position or a support position according to the needs of the user. In the closed position, the legs are retracted into the protective case to facilitate carrying and grasping. In the support position, the legs form an angle with the mobile phone, so that the mobile phone can be supported on a tabletop in an inclined state by using the legs, so that the user can view and operate the mobile phone without holding the mobile phone. However, traditional protective cases with rotating legs usually have one of these defects: 1) The legs and the protective case body are non-detachably connected, and after the legs are damaged, new legs cannot be replaced; 2) Even if the legs of some protective cases can be detached from and inserted into the protective case body, the detachment and insertion are relatively difficult; 3) Special positioning structures need to be provided on the legs and the protective case body to keep the legs in the closed position and the support position, which will increase the design difficulty and manufacturing cost. Summary of the Invention

[0004] In order to solve at least one of the above technical problems, this application provides a mobile phone protective case, its usage method, and a mobile phone set.

[0005] In a first aspect, a mobile phone protective case is proposed. The mobile phone has a rear surface facing away from the user and a protruding portion protruding from the rear surface, and the protruding portion carries a camera module. The protective case includes:

[0006] A bottom wall configured to cover the rear surface and having a first through hole for receiving the protruding portion;

[0007] A hollow portion penetrating the bottom wall and continuous with the first through hole, and an opening is formed at the junction of the hollow portion and the first through hole;

[0008] Two card slots respectively arranged on both sides of the opening and continuous with the opening, and the card slots are recessed from the inner wall surface of the first through hole into the bottom wall;

[0009] The rotating shaft has two end portions respectively snapped into the two card slots, and an intermediate portion connecting the two end portions and located in the opening. The end portions are snapped into the card slots by moving along the recessed direction of the card slots. And when the protective shell is assembled to the mobile phone, the protruding portion covers the notch of the card slot, thereby restricting the end portions within the card slots;

[0010] The leg has a shape complementary to the hollow portion and is connected to the intermediate portion in a manner capable of rotating relative to the bottom wall about the axis of the rotating shaft, and has a folded position and a supporting position based on the rotation;

[0011] In the folded position, the leg fills the hollow portion; in the supporting position, the leg leaves the hollow portion and forms an angle with the bottom wall to support the mobile phone.

[0012] In some possible embodiments, the card slot has:

[0013] The notch, which is continuous with the inner wall surface of the first through hole;

[0014] The slot cavity, which is located on the downstream side of the notch along the recessed direction and is configured to receive the end portion;

[0015] Wherein, the size of the notch is smaller than the sizes of the slot cavity and the end portion.

[0016] In some possible embodiments, the end portion is configured to:

[0017] By moving along the recessed direction, the bottom wall at the notch is pushed open to both sides, so as to enter the slot cavity, and is held in the slot cavity based on the restoration of the deformation of the bottom wall at the notch;

[0018] By moving in the opposite direction of the recessed direction, the bottom wall at the notch is pushed open to both sides, so as to leave the slot cavity via the notch.

[0019] In some possible embodiments, the leg is held in the supporting position by abutting against the peripheral surface of the protruding portion.

[0020] In some possible embodiments, the bottom wall has:

[0021] A convex ring, which surrounds the first through hole and extends from one side of the opening to the other side of the opening. The convex ring defines a part of the inner wall surface of the first through hole, and the two card slots are respectively arranged at both ends of the convex ring;

[0022] The leg has:

[0023] A head end portion, connected to the middle portion and formed to be thicker than the remaining portion of the leg.

[0024] In some possible embodiments, the thickness of the head end portion is the same as the thickness of the bottom wall at the convex ring;

[0025] In the closed position, the head end portion fills the opening, and the top surface of the head end portion is coplanar with the top surface of the convex ring.

[0026] In some possible embodiments, the mobile phone has a side surface connecting the front surface and the rear surface and an electrical connection socket recessed from the side surface;

[0027] The protective case includes a side wall extending from the periphery of the bottom wall, and the side wall is configured to cover the side surface;

[0028] The hollowed portion has a first part penetrating the bottom wall and a second part penetrating the side wall. The first part is continuous with the first through hole, the second part is continuous with the first part and extends to the electrical connection socket;

[0029] The leg has a first section complementary in shape to the first part and a second section complementary in shape to the second part; in the closed position, the second section fills a part of the second part and jointly defines a jack overlapping with the electrical connection socket with the remaining part of the second part.

[0030] In a second aspect, a method for using the protective case as described in the first aspect is proposed, including:

[0031] When the rotating shaft and the leg are combined with each other, by moving the rotating shaft along the recessed direction of the card slot, the end portion is snapped into the card slot;

[0032] When the first through hole is aligned with the protruding portion, the protective case is assembled onto the mobile phone, so that the protruding portion covers the notch of the card slot to limit the rotating shaft in the card slot.

[0033] In some possible embodiments, the method further includes:

[0034] When the protective case is detached from the mobile phone, by moving the rotating shaft in the opposite direction of the recessed direction of the card slot, the rotating shaft is detached from the card slot, and thereby the leg is detached from the bottom wall.

[0035] In a third aspect, a mobile phone set is proposed, including:

[0036] The protective case as described in the first aspect, and

[0037] the mobile phone described above.

[0038] According to the mobile phone protective case provided by the present application, the rotating shaft for connecting the leg and the bottom wall of the protective case is engaged with the card slot by moving along the recessed direction of the card slot. Therefore, the rotating shaft and the leg can be easily installed, and the assembled rotating shaft does not overly occupy the thickness of the bottom wall, nor is it necessary to specifically provide an obviously convex rotating shaft mounting seat on the bottom wall. Therefore, the structure redundancy of the protective case can be avoided. In addition, when the protective case is assembled to the mobile phone, the protruding part of the mobile phone itself just covers the notch of the card slot at the inner wall surface of the first through hole, thereby restricting the end part in the card slot and preventing the rotating shaft and the leg from detaching from the protective case.

[0075] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present application without creative efforts fall within the scope of protection of the present application. It can be understood that, without conflict, some technical means described in the various embodiments herein may be replaced or combined with each other.

[0076] In the description of the specification and claims of the present application, if there are terms such as "first", "second", etc., they are only used to distinguish the described objects and do not have any sequential or technical meaning. Thus, the objects defined with "first", "second", etc. may explicitly or implicitly include one or more of such objects. And, words such as "one" or "a" do not represent a quantity limitation, but rather indicate the existence of at least one, and "multiple" means not less than two.

[0077] To clearly describe the present technology, before introducing the protective shell 200, the mobile phone 100 as shown below is first introduced. The mobile phone 100 has a front surface S1 facing the user, a back surface S2 facing away from the user, a side surface S3 connecting the front surface S1 and the back surface S2, a protruding portion 1 protruding from the back 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 taking pictures, wherein the camera module 3 is carried in the protruding portion 1. The side surface S3 is located at the periphery of the mobile phone 100. Figure 1

[0078] ​The button 2 can be a button 2 for the user to control the screen off and on or a button 2 for controlling the volume, etc., and the button 2 is configured to move towards the inside of the mobile phone 100 when pressed, so that the protrusion 1 of the 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 the button 2 is released, it moves away from the inside of the mobile phone 100, so as to protrude from the side surface S3 of the mobile phone 100 again.

[0079] The electrical connection socket 4 is a socket for connecting a power line or a signal line, such as a Type-C socket. By inserting the end plug of the power line or signal line into the electrical connection socket 4, power or signals can be transmitted between the external device and the mobile phone 100.

[0080] 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. Among them, the aforementioned button 2 is specifically arranged 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 socket 4 is specifically arranged on the bottom side surface, that is, the electrical connection socket 4 is recessed from the bottom side surface.

[0081] The camera module 3 provides a shooting function for the mobile phone 100. Due to the requirement for a thin and light design of the mobile phone 100, the thickness space of the mobile phone 100 is limited. In order to reliably arrange a high-definition camera module 3 with specified performance, a protrusion 1 is formed at the rear surface S2 of the mobile phone 100. The protrusion 1 provides an additional installation space for the high-definition camera module 3 in the thickness direction D3. The protrusion 1 can be an integral structure with the rear wall of the mobile phone 100. More specifically, the two can be formed of 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 of the rear wall and the upper side position in the length direction D1. Of course, the protrusion 1 can also be formed as a circle or a rectangle or a triangle.

[0082] Next, please refer to Figures 2 to 8 and in combination with Figure 1 , introduce the protective case 200 provided by the first embodiment of the present application. The protective case 200 includes a bottom wall 5, a side wall 6, a hollowed-out portion 7, a card slot 8, a rotating shaft 10, and a leg 9.

[0083] 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 protruding portion 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 protruding portion 1 of the mobile phone 100 extends into the first through-hole 5a, and the peripheral surface S8 of the protruding portion 1 fits against the inner wall surface of the first through-hole 5a. In addition, since the rear surface S2 of the mobile phone is a flat surface, the first inner surface S4 is also formed as a flat surface adapted thereto. Moreover, for considerations of appearance, feel in use, and manufacturing cost, the first outer surface S5 is also formed as a flat surface.

[0084] The side wall 6 extends perpendicularly from the periphery of the bottom wall 5, and it 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. And the side wall 6 and the bottom wall 5 are of an integral structure. In this embodiment, the side wall 6 and the bottom wall 5 are integrally molded from a resin having sufficient structural strength. In other embodiments, the side wall 6 and the bottom wall 5 of the protective case 200 can also be formed from a metal material with flexibility.

[0085] 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 still be used normally when the mobile phone 100 is equipped with the protective case 200.

[0086] The hollowed-out portion 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, and extends to the electrical connection socket 4. That is, the hollowed-out portion 7 also penetrates the side wall 6 of the protective case 200. The first portion 7a is formed as a long strip extending in the length direction D1, and the size of the second portion 7b is slightly larger than the electrical connection socket 4 and surrounds the electrical connection socket 4 as a whole, so that the plug of the power line or signal line can be inserted into the electrical connection socket 4. And the side wall 6 is closed at the end side portion of the second portion 7b (connected by a short strip 6a), so as to prevent the side wall 6 from deforming away from each other on both sides at the second portion 7b, and thus maintain the structural integrity of the protective case 200. In addition, since the first portion 7a of the hollowed-out portion is continuous with the first through-hole 5a, an opening 11 is formed at the joint of the first portion 7a and the first through-hole 5a.

[0087] The leg 9 is rotatably mounted on the bottom wall 5 via a rotating shaft 10.

[0088] Specifically, the two card slots 8 are respectively arranged on both sides of the opening 11 and are continuous with the opening 11, and the card slots 8 are formed by being recessed from the inner wall surface of the first through hole 5a into the bottom wall 5. In the present embodiment, the card slot 8 is formed into a shape in which the slot opening 8a is narrow and the slot bottom is wide. Specifically, the card slot 8 includes a slot opening 8a and a slot cavity 8b, the slot opening 8a is continuous with the inner wall surface of the first through hole 5a, and the slot cavity 8b is located on the downstream side of the slot opening 8a along the recessed direction D4 of the card slot 8, that is, the slot cavity 8b is located on the inner side of the slot opening 8a. The size of the slot opening 8a is smaller than the size of the slot cavity 8b. In addition, based on the fact that the two card slots 8 have symmetrical positions and shapes, for simplicity, only one of the two card slots 8 is shown in the figure. In some embodiments, the bottom wall portion at the position of the card slot 8 can be thickened so that the card slot 8 can be easily set.

[0089] The rotating shaft 10 has two end portions 10a respectively inserted into the two slots 8, and a middle portion 10b connecting the two end portions 10a and located in the opening 11. Specifically, the groove cavity 8b of the slot 8 receives the end portion 10a of the rotating shaft 10. Moreover, the size of the slot 8a is smaller than the size of the end portion 10a. Therefore, in a normal use state, the end portion 10a of the rotating shaft 10 is blocked by the bottom wall 5 at the slot 8a, so that it is stably maintained in the slot 8, and based on this, the leg 9 can be prevented from accidentally detaching from the protective shell 200. In addition, the rotating shaft 10 can be made of metal.

[0090] The leg 9 has a shape complementary to the hollow portion 7, and is connected to the middle portion 10b of the shaft 10 in a manner that allows it to rotate relative to the bottom wall 5 around the axis of the shaft 10, and has a closed position and a support position based on the rotation. In this embodiment, the shaft 10 penetrates the head end 9a1 of the leg 9, and the shaft 10 can rotate relative to the head end 9a1 of the leg 9. In other embodiments, the shaft 10 is fixedly combined with the head end 9a1 of the leg 9, and the two cannot rotate relative to each other.

[0091] More specifically, the leg 9 has a first section 9a complementary in shape to the first portion 7a of the hollow portion 7, and a second section 9b complementary in shape to the second portion 7b of the hollow portion 7. In the closed position, the first section 9a fills the entirety of the second portion 7b and defines a portion of the inner wall surface of the first through hole 5a; the second section 9b fills a portion of the second portion 7b, thereby defining together with the remaining portion of the second portion 7b a socket 13 overlapping the electrical connection socket 4, and the socket 13 can provide a channel for the insertion of a power line or a signal line into the electrical connection socket 4. In the supporting position, the leg 9 leaves the hollow portion 7 and forms a certain angle (e.g., 60° or 90°) with the bottom wall 5 of the protective case 200, so that the mobile phone 100 can be supported on the table in an inclined state by using the open leg.

[0092] In addition, since, at the closed position, the second section 9b of the leg 9 defines a part of the wall of the socket 13, a user can insert the fingertips of a finger into the socket, thereby easily applying a force to the leg 9 to move it away from the mobile phone 100, causing the leg 9 to switch from the closed position to the support position. To enable the leg 9 to be stably held in the closed position, as Figure 8 shown, hemispherical locking protrusions can be provided on the leg 9, particularly on the second section 9b of the leg 9, and hemispherical depressions for receiving the aforesaid locking protrusions can be provided on the inner wall of the hollow portion 7, particularly on the second part 7b of the hollow portion 7, and multiple sets of locking protrusions and depressions can be provided. For the convenience of drawing, the locking protrusions and depressions are omitted in other drawings. Of course, other means can also be adopted to maintain the position of the leg 9 relative to the bottom wall 5. For example, a friction surface with concave and convex textures can be provided on the side of the leg 9.

[0093] Moreover, the end portion 10a of the rotating shaft 10 is snapped into the card slot 8 by moving along the recessed direction D4 of the card slot 8. Specifically, the end portion 10a of the rotating shaft 10 is configured to move along the recessed direction D4 of the card slot 8 to expand the bottom wall 5 at the notch 8a to both sides, so as to enter the cavity 8b. After the end portion 10a enters the relatively spacious cavity 8b, based on the restoration of the deformation of the bottom wall 5 at the notch 8a, the end portion 10a is held in the cavity 8b; and, by moving along the opposite direction D5 of the recessed direction to expand the bottom wall 5 at the notch 8a to both sides, so as to leave the cavity 8b via the notch 8a. In this way, the operator can grasp the leg 9 with the rotating shaft 10. When the two end portions 10a of the rotating shaft 10 are respectively aligned with the notches 8a of the two card slots 8, a downward force is applied to the leg 9, so that the end portion 10a of the rotating shaft 10 expands the bottom wall 5 at the notch 8a to both sides, so as to enter the cavity 8b, and the installation of the leg 9 and the bottom wall 5 is completed; in addition, when the leg 9 has been installed on the bottom wall 5, by inserting the fingertips into the socket and applying a force to the leg 9, so that the leg 9 leaves the closed position. Then, grasp the leg 9 and apply an upward force. The rotating shaft 10 moves toward the notch 8a side under the drive of the leg 9 and expands the bottom wall 5 with a certain degree of deformation at the notch 8a to both sides, so as to leave the card slot 8. Thus, the leg 9 is detached from the protective shell 200. As a result, after the leg 9 is damaged, a new leg 9 can be easily replaced. Based on this, in the factory packaging of the protective shell 200, multiple legs 9 can be included, but only one set of the parts other than the legs 9 is configured, because the frequently used leg 9 is more likely to be damaged than other components. Moreover, such a protective shell 200 and the mobile phone 100 can be packaged in the same package and sold as a whole mobile phone set (or mobile phone kit 1000). In addition, compared with the non-detachable assembly of the leg 9 to the protective shell 200, the design of this embodiment helps to reduce the manufacturing difficulty of the protective shell 200 and reduce the manufacturing cost of the protective shell 200.

[0094] In this embodiment, the leg 9 is held in the aforementioned supporting position in such a way that the peripheral surface S8 of the protruding portion 1 abuts against the expanded leg 9, thereby preventing the leg 9 from further rotating away from the hollow portion 7, so that the leg 9 and the bottom wall 5 maintain the aforementioned certain angle, that is, the leg 9 is held in this supporting position. In this way, this embodiment cleverly uses the protruding portion 1 of the mobile phone 100 itself to abut against the expanded leg 9, so that the leg 9 can be stably held in the supporting position (supporting angle), thereby reducing or even eliminating the structure on the protective shell 200 specifically used to position the angle of the leg 9, thereby simplifying the structure of the protective shell 200 and thus enhancing the cost-effectiveness.

[0095] The head end portion 9a1 of the leg 9 has an arc surface S9 around the rotating shaft 10. In this way, during the rotation of the leg 9 from the folded position to the supporting position, it is possible to prevent the head end portion 9a1 and the peripheral surface S8 of the protruding portion 1 from interfering with each other, so that the leg 9 cannot continue to rotate before reaching the supporting position.

[0096] Moreover, since the card slot 8 is formed by recessing from the inner wall surface of the first through hole 5a, when the protective case 200 is assembled to the mobile phone 100, the protruding portion 1 of the mobile phone 100 will cover the notch 8a of the card slot 8 to limit the end portion 10a of the rotating shaft 10 within the card slot 8 and prevent it from coming out. Thus, under the use of this protective case 200, it is further possible to prevent the leg 9 from accidentally detaching from the protective case 200.

[0097] Next, please refer to Figures 9 to 12 , Figures 9 to 12 FIG. shows a protective case 200 for a mobile phone 100 provided in the second embodiment of the present application. It has a structure similar to that of the protective case 200 in the first embodiment and can be understood with reference to the description of the first embodiment. For the sake of simplicity, the same or similar components are given the same or similar reference numerals, and the repetitive detailed description of their identical parts is omitted. Hereinafter, the differences between this embodiment and the first embodiment will be mainly described.

[0098] In this embodiment, the bottom wall 5 has a convex ring 12 that protrudes integrally from the first outer surface S5 and surrounds the first through hole 5a and extends from one side of the opening 11 to the other side of the opening 11. The convex ring 12 defines a part of the inner wall surface of the first through hole 5a, and two card slots 8 are respectively disposed at both end portions of the convex ring 12. Through such a design, without the need to thicken the bottom wall 5 of the protective case 200 as a whole, the protruding portion 1 that extends out of the first through hole 5a in the first embodiment can be covered in the circumferential direction by the convex ring 12, reducing the possibility of damage to the protruding portion 1; more advantageously, without the need to thicken the bottom wall 5 of the protective case 200 as a whole, the card slots 8 can be easily machined because the convex ring 12 provides sufficient thickness space for the machining of the card slots 8.

[0099] In this embodiment, when the protective case 200 is assembled to the mobile phone 100, the top surface of the convex ring 12 is coplanar with and adjacent to the top surface of the protruding portion 1. In some other embodiments, the top surface of the convex ring 12 can be slightly higher than the top surface of the protruding portion 1 to better protect the camera module 3 at the protruding portion 1.

[0100] The head end portion 9a1 of the leg 9 connected to the middle portion 10b of the rotating shaft 10 is formed to be larger than that in the case of the first embodiment. In this embodiment, the head end portion 9a1 of the leg 9 is formed to be thicker than the remaining portion of the leg 9, and the thickness of the head end portion 9a1 is substantially the same as the thickness of the bottom wall 5 at the convex ring 12. In the closed position, the head end portion 9a1 of the leg 9 fills the opening 11, and the top surface of the head end portion 9a1 is coplanar with the top surface of the convex ring 12. Therefore, the appearance of the protective case 200 at the convex ring 12 can be ensured.

[0101] Due to the arrangement of the thickened convex ring 12 and the thickened head end portion 9a1, the protective case 200 has higher structural strength at the convex ring 12 and the head end portion 9a1 compared with the case of the first embodiment. Therefore, the card slots 8 and the rotating shaft 10 provided at this part have better position stability.

[0102] Next, referring to Figure 13 , Figure 13 FIG. shows the state when the protective case 200 provided in the third embodiment of the present application is mounted on the mobile phone 100 (the leg 9 is in the closed position). It has a structure similar to that of the protective cases 200 of the first and second embodiments and can be understood with reference to the descriptions of the first and second embodiments. For the sake of simplicity, the same or similar reference numerals are given to their same or similar components, and the repetitive detailed descriptions of their same parts are omitted. Hereinafter, the differences between this embodiment and the first and second embodiments will be mainly described.

[0103] In the first and second embodiments, the leg 9 extends in the length direction D1 of the mobile phone 100 and the protective case 200, and the rotating shaft 10 extends along the width direction D2 of the mobile phone 100 and the protective case 200, so as to support the mobile phone 100 in the vertical screen mode on the tabletop. However, this embodiment is different. In this embodiment, the leg 9 extends in the width direction D2 of the mobile phone 100 and the protective case 200, and the rotating shaft 10 extends along the length direction D1 of the mobile phone 100 and the protective case 200, so as to support the mobile phone 100 in the horizontal screen mode on the tabletop.

[0104] Moreover, the second section 9b of the support leg 9 has a third through hole 9b1. In the closed position, the protruding button 2 of the mobile phone 100 extends into the third through hole 9b1, so that by means of the blocking of the inner surface of the third through hole 9b1 by the button 2, the support leg 9 is inhibited from leaving the closed position. 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, enabling the support leg 9 to be stably held in the closed position, thereby reducing or even eliminating the structure (for example, the aforementioned hemispherical convex and concave) on the protective case 200 specifically used to position the support leg 9, thus simplifying the structure of the protective case 200 and enhancing the cost-effectiveness accordingly.

[0105] The cross-sectional shape of the third through hole 9b1 corresponds to the button 2 of the mobile phone 100, and the cross-sectional dimension of the third through hole 9b1 can be equal to or slightly larger than the button 2. Through such a design, on the one hand, the shape fit between the button 2 and the third through hole 9b1 can be better utilized to inhibit the support leg 9 from leaving the closed position, and on the other hand, it does not interfere with the pressing and resetting of the button 2.

[0106] Although in Figure 13 the second part of the hollowed-out portion 7 is configured to penetrate the side wall 6 in the thickness direction D2 of the mobile phone 100, so that the side wall 6 is also open at the end side of the second part, that is, the end side of the hollowed-out portion 7, it can be understood based on the foregoing description that the side wall 6 of the protective case 200 can also be closed at the end side of the second part. For example, a short strip 6a similar to Figure 5 shown can be used to connect the side wall 6 at the end side of the hollowed-out portion 7.

[0107] Next, referring to Figures 14 to 16 , Figures 14 to 16 shows a protective case 200 for a mobile phone 100 provided by the fourth embodiment of the present application, which has a structure similar to that of the protective cases 200 of the first embodiment, the second embodiment, and the third embodiment, and can be understood with reference to the descriptions of the first embodiment, the second embodiment, and the third embodiment. Moreover, for the sake of simplicity, the same or similar reference numerals are given to their same or similar components, and the repetitive detailed descriptions of their same parts are omitted. Hereinafter, the differences between this embodiment and the first embodiment, the second embodiment, and the third embodiment will be mainly described.

[0108] In this embodiment, the protective shell 200 also has a convex ring 12. In the second and third embodiments, the convex ring 12 is an unclosed 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 convex ring 12 is a closed ring extending around 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 by the closed convex ring 12 (more specifically, a connecting portion 12a of the convex ring 12 described later), so that it is possible to prevent the bottom walls 5 from deforming away from each other on both sides at the opening 11, and improve the structural integrity of the protective shell 200.

[0109] The closed convex ring 12 has a connecting portion 12a extending at the opening 11 to connect both sides of the opening 11. When the leg 9 rotates away from the hollow portion 7 around the rotating shaft 10 to form a certain angle (for example, 60° or 90°) with respect 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 expanded leg 9, thereby preventing the leg 9 from rotating further away from the hollow portion 7 and keeping the leg 9 in a specified support position. Compared with the method of using the protruding portion 1 to abut against the leg 9 in the second embodiment, the support angle of using the convex ring 12 to support the leg 9 in this embodiment can better prevent the protruding portion 1 of the mobile phone 100 from being bruised.

[0110] In this fourth embodiment, the leg 9 can be mounted on the protective shell 200 from the side of the first inner surface S4 of the bottom wall 5 when the protective shell 200 is separated from the mobile phone 100.

[0111] The embodiment of the present application also provides a method for using a mobile phone protective shell. This method is applicable to the protective shell 200 described in the first to third embodiments of the foregoing embodiments. Referring to the foregoing routine, this method includes:

[0112] When the rotating shaft 10 and the leg 9 are combined with each other, by moving the rotating shaft 10 along the recessed direction D4 of the card slot 8, the end portion 10a and thus the rotating shaft 10 are snapped into the card slot 8;

[0113] When the first through hole 5a is aligned with the protruding portion 1, the protective shell 200 is assembled onto the mobile phone 100, so that the protruding portion 1 covers the notch 8a of the card slot 8 to limit the end portion 10a and thus the rotating shaft 10 in the card slot 8;

[0114] When it is necessary to disassemble for replacing or maintaining the leg 9, then when the protective shell 200 is detached from the mobile phone 100, by moving the rotating shaft 10 in the opposite direction D5 of the recessed direction of the card slot 8, the end portion 10a and thus the rotating shaft 10 are detached from the card slot 8, and thus the leg 9 is detached from the bottom wall 5.
