[0049] Reference Figure 1 As shown, a protective shell provided in this embodiment includes: a lower shell 1, wherein the lower shell 1 has a mounting cavity 10, and one side of the mounting cavity 10 is open; an upper cover 2, which is buckled on the open end of the mounting cavity 10; a sliding structure, including a sliding column 22 and a sliding groove 13, wherein one of the sliding column 22 and the sliding groove 13 is arranged on the upper cover 2, and the other is arranged on the lower shell 1, wherein the two ends of the sliding groove 13 are respectively a first end 11 and a second end 12, and the sliding column 22 is slidably and rotatably inserted in the sliding groove 13; when the sliding column 22 slides to the first end 11, the upper cover 2 closes the open end of the mounting cavity 10; when the sliding column 22 slides to the second end 12, the upper cover 2 rotates to the back side of the lower shell 1 with the sliding column 22 as the rotating shaft; a locking structure, wherein the locking structure is connected between the upper cover 2 and the lower shell 1, and is used to lock the upper cover 2 and the lower shell 1 with each other when the upper cover 2 closes the open end of the mounting cavity 10 and the upper cover 2 rotates to the back side of the lower shell 1.

[0050] Specifically, the lower shell 1 is generally in a rectangular plate-shaped structure and has a certain thickness to ensure that the formed mounting cavity 10 has a certain depth to accommodate an electronic device such as a mobile phone 3 or the like.

[0051] In this embodiment, the open side of the installation cavity 10 faces upward, that is, the upward end of the installation cavity 10 is open for taking and placing electronic equipment.

[0052] The upper cover 2 and the lower shell 1 are buckled with each other, and can slide and rotate to a specific position under the action of the sliding structure. Specifically, when the upper cover 2 is located above the lower shell 1, the upper cover 2 slides toward the first end 11 under the action of the sliding structure, thereby closing the installation cavity 10 on the lower shell 1. At this time, the electronic device such as a mobile phone 3 in the installation cavity 10 will be completely wrapped to protect it. When sliding toward the second end 12, the open end of the installation cavity 10 is gradually opened. When the upper cover 2 slides relatively to the second end 12 of the sliding groove 13, the entire upper cover 2 can be flipped to the back side of the lower shell 1, that is, the lower side of the lower shell 1, with the sliding column 22 as the rotation axis. At this time, the upper cover 2 and the lower shell 1 can still slide toward the first end 11 under the action of the sliding structure. For details, please refer to Figures 5 to 8 The change process of the upper cover and the lower shell is shown in .

[0053] In the above-mentioned whole process, the locking structure realizes locking of the upper cover 2 and the lower shell 1 in two states. The first state is that the upper cover 2 is located on the upper side of the lower shell 1 and completely closes the installation cavity 10. The other state is that the upper cover 2 is located on the back side, i.e., the lower side, of the lower shell 1 and completely slides to the first end 11. In the first state, the electronic device such as the mobile phone 3 is in a protected state, and the locking of the locking structure can further maintain this protected state, and avoid the accidental sliding of the upper cover 2 relative to the lower shell 1, which leads to the opening of the installation cavity 10; in the second state, the electronic device such as the mobile phone 3 is in use, and the locking of the locking structure can avoid the accidental sliding of the upper cover 2, and avoid interference caused by the accidental sliding of the upper cover 2 during use; in addition, during use, the upper cover 2 and the lower shell 1 are both located on the back side, i.e., the lower side, of the electronic device such as the mobile phone 3. When the mobile phone 3 accidentally falls, the upper cover 2 and the lower shell 1 can play a double protection. It can be imagined that the gap reserved between the upper cover 2 and the lower shell 1 due to the need for relative sliding can form a certain buffer, thereby reducing the impact force on the electronic device such as the mobile phone 3.

[0054] Compared with the traditional electronic device protective shell, the protective shell provided in the present application can protect the screen surface of the electronic device such as the mobile phone 3 by sliding the upper cover 2, thereby avoiding damage to the screen of the electronic device due to accidental bumps or falls; under the action of the sliding structure, the upper cover 2 can very conveniently protect the electronic device, without the need to assemble multiple parts like the traditional protective shell, and the use process is very convenient. In addition, when the upper cover 2 completely covers the installation cavity 10 and the upper cover 2 is located on the back side of the lower shell 1, the upper cover 2 is locked relative to the lower shell 1 by the locking structure, which ensures the protection stability of the electronic device when it is in a protected state, and also avoids the interference of the upper cover 2 with the use process caused by accidental sliding when the electronic device is in use.

[0055] Reference Figures 2 to 4 As shown, in some further embodiments, the locking structure includes a limiting protrusion 15 and a limiting groove 24, one of the limiting protrusion 15 and the limiting groove 24 is arranged on the upper cover 2, and the other is arranged on the lower shell 1, and the number of the limiting grooves 24 is two, and the two limiting grooves 24 are spaced apart and arranged opposite to each other along the length direction of the sliding groove 13.

[0056] In this embodiment, the locking structure is locked by a limiting protrusion 15 and a limiting groove 24. Specifically, the limiting protrusion 15 can be set on the upper cover 2, and the limiting groove 24 can be set on the lower shell 1. Alternatively, the limiting protrusion 15 is set on the lower shell 1, and the limiting groove 24 is set on the upper cover 2. The above two methods can both achieve the locking of the upper cover 2 and the lower shell 1.

[0057] There are two limiting grooves 24, which are respectively located at the two ends along the length direction of the sliding groove 13. For example, when the limiting grooves 24 are set on the lower shell 1, the opening directions of the two limiting grooves 24 are the same, both facing the sliding direction of the upper cover 2 relative to the lower shell 1 when the installation cavity 10 is opened. In actual process, the limiting groove 24 can be specifically opened on a small protrusion protruding relative to the side wall of the lower shell 1 to avoid the interference of the limiting protrusion 15 on the lower shell 1 with the position where the limiting groove 24 is not set in the lower shell 1; for example, when the limiting grooves 24 are set on the upper cover 2, the opening directions of the two limiting grooves 24 are opposite, that is, the opening of a limiting groove 24 located at the first end 11 is back to the second end 12, and the opening of a limiting groove 24 located at the second end 12 is back to the first end 11. However, no matter which of the above methods is adopted, the upper cover 2 and the lower shell 1 are always locked by the locking structure at the appropriate time.

[0058] It should be noted that the aforementioned “opposite to each other” indicates a positional relationship of the two limiting slots 24 relative to each other in the length direction of the sliding slot 13 , and does not impose any limitation on the opening direction of the limiting slots 24 .

[0059] Reference Figure 2 As shown, the limiting protrusion 15 includes a clamping portion 150 and a limiting portion 151 which are sequentially arranged along the length direction of the sliding groove 13; the width of at least part of the clamping portion 150 is greater than the width of the limiting portion 151; the limiting groove 24 includes a clamping groove 240 and a limiting groove 241 which are sequentially connected along the length direction of the sliding groove 13, the limiting portion 151 is adapted to the limiting groove 241, and the clamping portion 150 is adapted to the clamping groove 240.

[0060] The limiting protrusion 15 is specifically as follows, it includes a snap-fitting portion 150 and a limiting portion 151 which are sequentially arranged along the length direction of the sliding groove 13. Correspondingly, the limiting groove 24 includes a snap-fitting groove 240 and a limiting groove 241. During actual locking, the limiting portion 151 is correspondingly inserted into the limiting groove 241, and the snap-fitting portion 150 is correspondingly inserted into the snap-fitting groove 240.

[0061] At least a portion of the snap-fitting portion 150 has a width greater than that of the limiting portion 151, so that when the limiting protrusion 15 cooperates with the limiting groove 24, there are multiple snap-fitting force-bearing surfaces of different widths, thereby increasing the resistance to shaking in the width direction. In addition, multiple snap-fitting force-bearing surfaces of different widths will also make the limiting protrusion 15 and the limiting groove 24 have at least two calibration verification benchmarks at the beginning of the design, avoiding the matching error caused by the error of a single width being omitted, and ultimately causing the locking failure of the upper cover 2 and the lower shell 1.

[0062] It should be explained that the aforementioned definition of “width” refers to the direction of the depth of the installation cavity 10 , which can also be understood as the direction of the thickness of the lower shell 1 .

[0063] In some further embodiments, the limiting protrusion 15 is provided on the lower shell 1, and the clamping portion 150 is located at the end of the limiting portion 151 away from the sliding groove 13; the two limiting grooves 24 are respectively provided at the two ends of the upper cover 2, and the end of the clamping groove 240 away from the limiting groove 241 has a sliding entrance 23, the sliding entrances 23 of the two limiting grooves 24 are in opposite directions, and the width of the sliding entrance 23 is smaller than the maximum width of the clamping portion 150.

[0064] In a preferred embodiment, the limiting protrusion 15 is located on the lower shell 1, and the limiting slot 24 is located on the upper cover 2. Specifically, the clamping portion 150 is located at the end of the sliding slot 13 relative to the limiting portion 151 to ensure that the narrower limiting portion 151 is first clamped with the limiting slot 24 before the wider clamping portion 150. For the limiting slot 24, as described above as a possible description of its arrangement on the upper cover 2, the openings of the two limiting slots 24 are opposite. For ease of understanding, a sliding entrance 23 is introduced in this embodiment. The sliding entrance 23 is arranged at one end of the clamping slot 240 away from the limiting slot 241. When clamping, the limiting protrusion 15 always slides in from the sliding entrance 23.

[0065] In some further embodiments, the limiting slot 24 further includes a guide slot 242 , which is arranged along the length direction of the sliding slot 13 and communicates with the sliding entrance 23 ; the width of the guide slot 242 gradually decreases along the direction approaching the sliding entrance 23 .

[0066] The main function of the guide groove 242 is to facilitate the cooperation between the limiting protrusion 15 and the limiting notch 24. The guide groove 242 is flared, that is, the closer it is to the sliding entrance 23, the smaller its width is, making it easier for the limiting protrusion 15 to dock with the limiting notch 24 when they are about to cooperate.

[0067] In some further embodiments, the sliding post 22 is located between the two limiting slots 24 and is close to one of the limiting slots 24 .

[0068] When the limiting groove 24 is provided on the upper cover 2, the sliding post 22 is located between the two limiting grooves 24 and close to one of the limiting grooves 24 that cooperates with the limiting protrusion 15 when the installation cavity 10 is completely closed, so that in the process of opening the installation cavity 10, the entire upper cover 2 slides more thoroughly in the process of opening the installation cavity 10, that is, the installation cavity 10 can be opened with a larger opening.

[0069] When the sliding column 22 is arranged on the upper cover 2, when the upper cover 2 is flipped to the back side of the lower shell 1 relative to the lower shell 1, the upper cover 2 and the lower shell 1 can present Figure 7 The state shown, that is, a supporting structure is formed, at which time the lower shell 1 and the upper cover 2 form a certain angle with each other, thereby forming a supporting effect on the electronic device such as a mobile phone to meet certain usage requirements.

[0070] In some further embodiments, the width of the clamping portion 150 gradually increases and then gradually decreases along the length direction of the sliding groove 13, the width of the limiting portion 151 is equal to the width of the end where the clamping portion 150 and the limiting portion 151 are connected, and the end surface of the limiting portion 151 away from the clamping portion 150 is set to a convex arc surface.

[0071] Specifically, the width of the clamping portion 150 gradually increases and then gradually decreases to form a clamping structure with the clamping groove 240, that is, the clamping portion 150 can be clamped with the clamping groove 240 only under the action of a specific external force, and the clamping portion 150 can be disengaged from the clamping groove 240 only under the action of a specific external force; the raised arc surface of the limiting portion 151 can also play a certain guiding role in the cooperation between the limiting protrusion 15 and the limiting groove 24, thereby ensuring the smooth cooperation between the limiting protrusion 15 and the limiting groove 24.

[0072] Reference Figure 2 and Fig. 9 As shown, in some further embodiments, the cross-section of the clamping portion 150 includes a first arc line 40, which is a major arc; the cross-section of the limiting portion 151 includes a first line segment 41 and a second arc line 42, and the number of the first line segments 41 is two, the two first line segments 41 are arranged in parallel, and one end of the two first line segments 41 is respectively connected to the two ends of the first arc line 40, and the other end of the two first line segments 41 is respectively connected to the two ends of the second arc line 42.

[0073] The specific shape of the limiting protrusion 15 can refer to Fig. 9 The cross-sectional schematic diagram of the limiting protrusion 15 shown is a cross-sectional schematic diagram of the limiting protrusion 15, wherein the cross-section of the clamping portion 150 includes a first arc line 40 which is a major arc, and the cross-section of the limiting portion 151 includes a second arc line 42 and two mutually parallel first line segments 41.

[0074] In some further embodiments, entry and exit grooves 14 are provided on the outer sides of the two side walls of the lower shell 1 along the length direction, one end of the entry and exit groove 14 is connected to the corresponding sliding groove 13, and the other end extends to the end surface of the lower shell 1 in the thickness direction.

[0075] The aforementioned thickness direction indicates the depth direction of the installation cavity 10 , and is also the width direction of the limiting protrusion 15 .

[0076] The entry and exit groove 14 is mainly used for the cooperation and disengagement of the sliding column 22 and the sliding groove 13. In actual situations, the end of the entry and exit groove 14 away from the sliding groove 13 can be set on a side of the installation cavity 10 in the lower shell 1, or it can be set on a side facing away from the installation cavity 10. Of course, in some other embodiments, two entry and exit grooves 14 can also be set, and the ends of the two entry and exit grooves 14 away from the sliding groove 13 are opened on two side surfaces respectively, which also makes it easier for the lower shell 1 and the upper cover 2 to cooperate.

[0077] In some further embodiments, the upper cover 2 includes a front plate 20 and two side plates 21, the two side plates 21 are respectively connected to a set of opposite sides of the upper cover 2, one end of the side plate 21 is provided with a clearance notch 25, and the lower shell 1 is provided with steps 16 on the two side walls along its length direction corresponding to the clearance notch 25; when the upper cover 2 is completely closed at the open end, the step 16 abuts against the clearance notch 25.

[0078] The upper cover 2 is a semi-frame structure. Specifically, the upper cover 2 includes a front plate 20 and two side plates 21 . The two side plates 21 are connected to a set of opposite sides of the upper cover 2 . The limiting grooves 24 and the sliding posts 22 are both arranged on the two side plates 21 .

[0079] Reference Figure 2 and Figure 4 As shown, a step 16 is provided on one end of the side wall of the lower shell 1 close to the limiting protrusion 15. When the upper cover 2 completely closes the installation cavity 10, the two side panels 21 in the upper cover 2 are shorter than the front panel 20 at one end facing the step 16, thereby forming a clearance notch 25 on the side panel 21 to exactly cooperate with the step 16.

[0080] The cooperation between the clearance notch 25 and the step 16 can reduce to some extent the impact of the sliding groove 13 on the sliding column 22 when the upper cover 2 is about to completely close the installation cavity 10 , thereby extending the service life of the sliding column 22 .

[0081] In addition, from the user's perspective, when the lower shell 1 is placed in the hand, part of the palm can contact the side wall of the step 16 instead of directly contacting the outer side of the side panel 21, thereby effectively avoiding friction between the side panel 21 and the palm when sliding the upper cover 2, thereby avoiding interference of the palm with the sliding process of the upper cover 2.

[0082] In some further embodiments, the limiting groove 24 is located on the inner side of the side plate 21 to ensure that the entire exterior of the protective shell is round and neat, while also giving it a simple appearance.

[0083] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application.
