Description

Technical Field

[0001] The present application relates to the technical field of mobile phones, and in particular, to a protective case for a mobile phone and a mobile phone kit having the same. Background Art

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

[0003] There have already appeared protective cases with legs on the market. 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 gripping. 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 gripping the mobile phone. However, traditional protective cases with rotating legs usually have one of these defects: 1) The legs and the main body of the protective case are non-detachably connected. 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 main body of the protective case, the detachment and insertion are relatively difficult; 3) Special positioning structures need to be provided on the legs and the main body of the protective case to keep the legs in the closed position and the support position, which will increase the design difficulty and manufacturing cost.

[0074] To make the purpose, technical solution and advantages of this application clearer, the technical solution of the embodiments of this application will be clearly and completely described below in conjunction with the drawings of the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of this application. It can be understood that, without conflict, some technical means described in the various embodiments herein can be replaced or combined with each other.

[0075] In the description of the specification and claims of this 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 indicate a quantity limitation, but rather indicate the existence of at least one, and "multiple" means not less than two.

[0076] To clearly describe this technology, before introducing the protective case 200, first introduce the mobile phone 100 adapted thereto as Figure 1 shown. The mobile phone 100 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 protruding portion 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 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.

[0077] 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 size, etc., and the button 2 is configured to: move towards the inside of the mobile phone 100 by being pressed, so that the protruding portion 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; by releasing the pressing of the button 2, 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.

[0078] 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 the signal line into the electrical connection socket 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. 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.

[0080] 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 protruding portion 1 is formed at the rear surface S2 of the mobile phone 100. The protruding portion 1 provides an additional installation space for the high-definition camera module 3 in the thickness direction D3. The protruding portion 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 protruding portion 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 position in the length direction D1 of the rear wall. Of course, the protruding portion 1 can also be formed as a circle, a rectangle or a triangle.

[0081] Next, please refer to Figures 2 to 8 and in combination with Figure 1 , the protective case 200 provided by the first embodiment of the present application will be introduced. The protective case 200 includes a bottom wall 5, a side wall 6, a hollow portion 7, a card slot 8, a rotating shaft 10 and a 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 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 with 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, considering appearance, use feel and manufacturing cost, the first outer surface S5 is also formed as a flat surface.

[0083] The side wall 6 extends vertically from the periphery of the bottom wall 5, having a second inner surface S6 covering the aforementioned side surface S3 and a second outer surface S7 opposite to the second inner surface S6. Also, 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 with 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 metallic material with flexibility.

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

[0085] The hollowed-out portion 7 has a first part 7a formed on the bottom wall 5 and a second part 7b formed on the side wall 6. The first part 7a penetrates the first inner surface S4 and the first outer surface S5 and is continuous with the first through hole 5a. The second part 7b penetrates the second inner surface S6 and the second outer surface S7 and is continuous with the first part 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 part 7a is formed as a long strip extending in the length direction D1, and the size of the second part 7b is slightly larger than that of the electrical connection socket 4 and entirely 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. Also, the side wall 6 is closed (connected by a short strip 6a) at the end side portion of the second part 7b, thereby preventing the side wall 6 from deforming away from each other on both sides at the second part 7b, and thus maintaining the structural integrity of the protective case 200. Additionally, since the first part 7a of the hollowed-out portion 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 leg 9 is rotatably mounted on the bottom wall 5 via a rotating shaft 10.

[0087] Specifically, 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 recessing from the inner wall surface of the first through hole 5a into the bottom wall 5. In this embodiment, the card slots 8 are formed in a shape with a narrow slot opening 8a and a wide slot bottom. Specifically, the card slots 8 include 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 in the recessing direction D4 of the card slot 8, that is, the slot cavity 8b is located inside the slot opening 8a. The size of the slot opening 8a is smaller than that of the slot cavity 8b. Additionally, based on the two card slots 8 having symmetric 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 where the card slots 8 are located can be thickened to facilitate the setting of the card slots 8.

[0088] The rotating shaft 10 has two end portions 10a respectively snapped into the two card slots 8, and an intermediate portion 10b connecting the two end portions 10a and located in the opening 11. Specifically, the cavity 8b of the card slot 8 receives the end portion 10a of the rotating shaft 10. And the size of the notch 8a is smaller than the size of the end portion 10a. Therefore, in the normal use state, since the end portion 10a of the rotating shaft 10 is blocked by the bottom wall 5 at the notch 8a, it is stably held in the card slot 8, and based on this, the leg 9 can be prevented from accidentally detaching from the protective case 200. In addition, the rotating shaft 10 can be made of metal material.

[0089] The leg 9 has a shape complementary to the hollow portion 7, and is connected to the intermediate portion 10b of the rotating shaft 10 in a manner that can rotate relative to the bottom wall 5 about the axis of the rotating shaft 10, and has a folded position and a support position based on this rotation. In this embodiment, the rotating shaft 10 passes through the head end portion 9a1 of the leg 9, and the rotating shaft 10 can rotate relative to the head end portion 9a1 of the leg 9. In other embodiments, the rotating shaft 10 is fixedly coupled to the head end portion 9a1 of the leg 9, and the two cannot rotate relative to each other.

[0090] More specifically, the leg 9 has a first section 9a with a shape complementary to the first part 7a of the hollow portion 7 and a second section 9b with a shape complementary to the second part 7b of the hollow portion 7. In the folded position, the first section 9a fills the entire second part 7b and defines a part of the inner wall surface of the first through hole 5a; the second section 9b fills a part of the second part 7b, so as to jointly define a jack 13 overlapping with the electrical connection socket 4 with the remaining part of the second part 7b. The jack 13 can provide a channel for the insertion of a power line or a signal line into the electrical connection socket 4. In the support position, the leg 9 leaves the hollow portion 7 and forms a certain angle (for example, 60° or 90°) with the bottom wall 5 of the protective case 200, so as to support the mobile phone 100 in an inclined state on the tabletop by means of the spread leg.

[0091] In addition, since in the folded position, the second section 9b of the leg 9 defines a part of the wall of the jack 13, the user can insert the fingertips of the fingers into the socket, so as to easily apply a force to the leg 9 to move it away from the mobile phone 100, so that the leg 9 is switched from the folded position to the support position. In order to enable the leg 9 to be stably held in the folded position, as Figure 8 shown, hemispherical convex bumps can be provided on the leg 9, especially on the second section 9b of the leg 9, and hemispherical depressions for receiving the aforementioned convex bumps can be provided on the inner wall of the hollow portion 7, especially on the second part 7b of the hollow portion 7, and multiple groups of convex bumps and depressions can be provided. For the convenience of drawing, the convex bumps and depressions are omitted in other drawings. Of course, other methods can also be used 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.

[0092] 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 moves away from 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 case 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 case 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 legs 9 are more likely to be damaged than other components. Moreover, such a protective case 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 way of assembling the leg 9 to the protective case 200 in a non-detachable manner, the design of this embodiment helps to reduce the manufacturing difficulty of the protective case 200 and reduce the manufacturing cost of the protective case 200.

[0093] 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, so as to prevent the leg 9 from further rotating away from the hollow portion 7, so that the leg 9 and the bottom wall 5 are kept at 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 case 200 specifically used to position the angle of the leg 9, thereby simplifying the structure of the protective case 200 and thus improving the cost effectiveness.

[0094] The head end portion 9a1 of the support leg 9 has an arc surface S9 around the rotation shaft 10. In this way, during the process of the support leg 9 rotating from the folded position to the support 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 support leg 9 cannot continue to rotate before reaching the support position.

[0095] 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 rotation 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 support leg 9 from accidentally detaching from the protective case 200.

[0096] 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 by referring to the description of the first embodiment. Moreover, 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.

[0097] In this embodiment, the bottom wall 5 has a convex ring 12 which protrudes integrally from the first outer surface S5, 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 arranged 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 extending outside the first through hole 5a in the first embodiment can be partially 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 processed because the convex ring 12 provides sufficient thickness space for the processing of the card slots 8.

[0098] 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.

[0099] 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.

[0100] Due to the configuration of the thickened convex ring 12 and the thickened head end portion 9a1, compared with the case of the first embodiment, the protective case 200 has higher structural strength at the convex ring 12 and the head end portion 9a1. Therefore, the card slots 8 and the rotating shaft 10 provided at this part have better position stability.

[0101] Next, refer to Figure 13 , Figure 13 which 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.

[0102] 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.

[0103] 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 on the protective case 200 specifically used to position the support leg 9 (for example, the aforementioned hemispherical convex and concave), thus simplifying the structure of the protective case 200 and enhancing the cost-effectiveness accordingly.

[0104] The cross-sectional shape of the third through hole 9b1 corresponds to that of 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 that of 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, the pressing and resetting of the button 2 are not hindered.

[0105] 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 introduction 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 that Figure 5 shown can be used to connect the side wall 6 at the end side of the hollowed-out portion 7.

[0106] Next, referring to Figures 14 to 16 Figures 14 to 16 FIG. 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. It can be understood by referring 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.

[0107] In this embodiment, the protective case 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 on 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, the connecting portion 12a of the convex ring 12 described later), so that the bottom walls 5 can be prevented from deforming away from each other on both sides at the opening 11, improving the structural integrity of the protective case 200.

[0108] 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 further rotating away from the hollow portion 7 and keeping the leg 9 in a specified supporting position. Compared with the method of using the protruding portion 1 to abut against the leg 9 in the second embodiment, the supporting 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.

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

[0110] The embodiment of the present 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 foregoing routine, this method includes:

[0111] 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;

[0112] When the first through hole 5a is aligned with the protruding portion 1, the protective case 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;

[0113] When it is necessary to disassemble for replacing or maintaining the leg 9, then when the protective case 200 is detached from the mobile phone 100, by moving the rotating shaft 10 along 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.
