[0042] In order to better protect the tablet computer, users often install a protective case on the tablet computer. In the prior art, there are two types of protective cases for tablet computers. One type is a case and a cover that are integrally connected. When in use, the cover needs to be folded under the case, which is not convenient for users to hold due to the overall thickness. The other type is a case and a cover that are detachably connected, for example, by multiple magnets, or the cover is detachably connected to the bottom case by being sleeved on a hinge such as a pin, and fixed with screws. However, this structure is relatively complicated, with many parts, which easily increases the overall weight and is not conducive to disassembly and assembly.

[0043] In order to solve this technical problem, the utility model provides a tablet computer protective cover.

[0044] See also Figures 1 to 7In one embodiment of the present invention, the tablet computer protective cover includes a shell 10, a cover 20 and a locking protrusion 13; the shell 10 is provided with a storage space 101 for accommodating the tablet computer, the shell 10 has a frame edge 11, the frame edge 11 is provided with a slide groove 12 along its extension direction, and the slide groove 12 is provided with a first notch 121 on the side away from the storage space 101; the cover 20 includes a cover flange 21, and the cover flange 21 is provided with a quick release structure 22, and the quick release structure 22 includes a connecting arm 221 and a buckle 222 protruding from the cover flange 21, one end of the connecting arm 221 is connected to the cover flange 21, and a storage groove 23 is formed between the connecting arm 221 and the cover flange 21, and the connecting arm 221 is provided with a first notch 121. The other end is connected to the buckle protrusion 222 on one side of the cover flange 21, and the buckle protrusion 222 and the cover flange 21 form an opening 231; the locking protrusion 13 is arranged in the slide groove 12, and is located on the side of the first notch 121 in the extension direction of the frame edge 11, and the first notch 121 is used for the quick-release structure 22 to extend into the slide groove 12; when the quick-release structure 22 extends into the slide groove 12, and after the cover body 20 and the shell 10 move relative to each other, the locking protrusion 13 passes through the opening 231 and is locked in the accommodating groove 23; in this way, the convenience of disassembly and assembly of the shell 10 and the cover body 20 can be improved, and the weight of the tablet computer protective cover can be quickly reduced, which is convenient for users to hold and improves the user experience.

[0045] In the technical solution of the present invention, a slide groove 12 is provided on the frame edge 11 of the shell 10, and a locking protrusion 13 is provided in the annular groove. A first notch 121 is provided on the side of the slide groove 12 away from the accommodating space 101, and a quick-release structure 22 is provided on the cover flange 21 of the cover body 20. An opening 231 is formed between the quick-release structure 22 and the cover flange 21 to face the accommodating groove 23 of the locking protrusion 13. Then, the quick-release structure 22 can extend into the slide groove 12 through the first notch 121, and after the cover body 20 and the shell 10 move relative to each other, the locking protrusion 13 is locked in the accommodating groove 23, completing the work. The assembly of the cover body 20 and the shell 10 can not only ensure the connection strength of the cover body 20 and the shell 10, but also effectively protect the tablet computer built into the accommodating space 101; and benefiting from the snap-fitting of the quick-release structure 22 and the latch 13, the relative sliding of the cover body 20 and the shell 10 can make the quick-release structure 22 slide along the slide groove 12 toward the first notch 121 and quickly separate from the latch 13, thereby improving the convenience of disassembly and assembly of the shell 10 and the cover body 20, and further, helping to quickly reduce the weight of the tablet computer protective cover, making it more convenient for users to hold, and improving the user experience.

[0046] Specifically, the chute 12 extends along the extension direction of the frame edge 11 to provide a guide for the quick-release structure 22 to slide within the chute 12. The first notch 121, which is located away from the latching protrusion 13, forms the starting end of the chute 12, ensuring that the quick-release structure 22 can translate toward the latching protrusion 13. The latching protrusion 13 is connected between the opposite groove walls of the chute 12, that is, it extends along the thickness direction of the frame edge 11, thereby achieving a latching connection between the latching protrusion 13 and the quick-release structure 22. The latching protrusion 13 can be formed on the frame edge 11 by stamping, integral molding, or other methods.

[0047] The quick-release structure 22 includes a connecting arm 221 and a buckle protrusion 222. The connecting arm 221 is protruded from the side of the cover flange 21 facing the frame edge 11, so that after the connecting arm 221 extends into the slide groove 12, the cover flange 21 can fit with the frame edge 11, thereby increasing the effective contact area between the cover body 20 and the shell 10, and improving the connection stability between the cover body 20 and the shell 10; after the latching protrusion 13 is latched in the receiving groove 23, because the buckle protrusion 222 is protruded from the side of the connecting arm 221 facing the cover flange 21, an opening 231 connected to the receiving groove 23 is formed, the buckle protrusion 222 can effectively prevent the latching protrusion 13 from escaping from the receiving groove 23, and can also reduce the shaking of the latching protrusion 13 in the receiving groove 23 to a certain extent, further strengthening the connection stability between the cover body 20 and the shell 10. The quick-release structure 22 and the cover flange 21 can be fixed into a whole by, for example, injection molding. The manufacturing material of the quick-release structure 22 can be a flexible structure such as soft rubber, so that the quick-release structure 22 has a deformable property to achieve rapid connection and separation of the quick-release structure 22 and the locking protrusion 13.

[0048] like Figures 1 to 3 As shown, the cover 20 is provided with a plurality of folds that can be used to fold the cover 20 into a supporting portion. Preferably, two folds are evenly arranged so that the cover 20 can be folded into a three-dimensional triangle after being flipped open. Figure 1 and Figure 2 The shell 10 and the tablet computer are stably supported, wherein a plurality of frame edges 11 are provided, and one of the frame edges 11 is connected to the cover flange 21 through the snap-fitting of the latch 13 and the quick-release structure 22. It can be understood that the accommodating space 101 is formed by the bottom plate of the shell 10 and the plurality of frame edges 11 provided along the periphery of the bottom plate. In order to meet the needs of users to place the tablet computer horizontally or vertically, a slide groove 12 is provided on at least two adjacent frame edges 11, and a latch 13 is provided in the slide groove 12. In this way, when the tablet computer is placed horizontally or vertically, the shell 10 can provide the corresponding frame edge 11 to be connected to the quick-release structure 22 on the cover flange 21, thereby improving the placement stability of the tablet computer.

[0049] In addition, providing the slide grooves 12 and the corresponding latching protrusions 13 on the multiple frame edges 11 can reduce the overall weight of the shell 10 to a certain extent and ensure the structural stability of the slide grooves 12. Moreover, when the side of the slide groove 12 facing the accommodating space 101 is provided as a through hole, the idle slide groove 12 can serve as a heat dissipation hole to facilitate the heat dissipation of the tablet computer.

[0050] Furthermore, in an embodiment of the present invention, two quick-release structures 22 are arranged at intervals. By arranging two quick-release structures 22 on the cover flange 21, a slide groove 12 and a latching protrusion 13 arranged in the slide groove 12 are correspondingly provided on the frame edge 11. In this way, when the cover body 20 and the shell 10 are snap-fitted through the quick-release structure 22 and the latching protrusion 13, it is beneficial to improve the connection strength between the cover body 20 and the shell 10, and ensure a stable connection between the cover body 20 and the shell 10.

[0051] The maximum distance between the two quick-release structures 22 is less than the minimum length of the frame edge 11. It can be understood that each frame edge 11 includes a long frame edge 11 and a short frame edge 11, and the maximum distance between the two quick-release structures 22 is less than the minimum length of the frame edge 11, specifically less than the minimum length of the short frame edge 11 in its extension direction. In this way, it can be ensured that the two quick-release structures 22 on the cover flange 21 are suitable for the two card protrusions 13 on the long frame edge 11 and the short frame edge 11 of the shell 10, thereby improving the assembly flexibility of the shell 10 and the cover body 20 to meet the user's usage needs.

[0052] See also Figure 5 In an embodiment of the present invention, the connecting arm 221 includes a first connecting segment 2211 and a second connecting segment 2212, one end of the first connecting segment 2211 is connected to the cover flange 21, one end of the second connecting segment 2212 is connected to the first connecting segment 2211, and the other end of the second connecting segment 2212 is connected to the buckle protrusion 222 facing the side of the cover flange 21; in this way, it is convenient to form a receiving groove 23 and an opening 231 between the connecting arm 221 and the cover flange 21.

[0053] Among them, in the extension direction of the frame edge 11, the width of the second connecting section 2212 is smaller than the width of the first slot 121, that is, the width of the second connecting section 2212 is smaller than the width of the first slot 121. When the quick-release structure 22 is moved toward the first slot 121, the quick-release structure 22 can smoothly pass through the first slot 121 and extend into the slide groove 12, or smoothly detach from the slide groove 12 from the first slot 121, thereby improving the convenience of disassembly and assembly of the cover body 20 and the shell body 10.

[0054] See also Figures 2 to 3 、 Figures 5 to 7In an embodiment of the present invention, a second notch 122 is further provided on the side of the slide groove 12 away from the accommodating space 101, and the locking protrusion 13 is located between the first notch 121 and the second notch 122. It can be understood that the side of the second notch 122 away from the locking protrusion 13 is the terminal end of the slide groove 12, which can not only restrict the further sliding of the quick-release structure 22, but also extend the slide groove 12 so that the slide groove 12 corresponding to the second notch 122 provides accommodating space for the buckle protrusion 222 and part of the connecting arm 221, thereby completing the locking connection between the quick-release structure 22 and the locking protrusion 13.

[0055] Furthermore, when the latching protrusion 13 is inserted into the receiving slot 23, the latching protrusion 222 is exposed at the second notch 122. Furthermore, when the side of the slide slot 12 facing the receiving space 101 is provided with a through hole, the outlet area of the slide slot 12 is increased, thereby facilitating heat dissipation for the tablet computer. However, in other embodiments, the slide slot 12 does not have the second notch 122.

[0056] Furthermore, in an embodiment of the present invention, in the extension direction of the frame edge 11, the width of the second notch 122 is smaller than the width of the first notch 121, which can avoid the distance between the terminal end of the slide groove 12 and the card protrusion 13 being too large, and facilitate the connection between the quick-release structure 22 and the card protrusion 13 within the limited slide groove 12, while ensuring the structural stability of the frame edge 11; and it can also reduce the space for relative movement between the quick-release structure 22 and the card protrusion 13, thereby reducing shaking.

[0057] Optionally, in an embodiment of the present invention, when the latching protrusion 13 is latched in the accommodating groove 23, the other end of the connecting arm 221 is spaced apart from the groove wall of the slide groove 12, that is, the second connecting section 2212 is spaced apart from the groove side wall of the slide groove 12, which can not only prevent the connecting arm 221 from colliding with the groove wall of the slide groove 12, but also provide deformation space when the connecting arm 221 needs to be deformed, thereby improving the connection reliability and disassembly convenience of the shell 10 and the cover body 20.

[0058] Optionally, in an embodiment of the present invention, the connecting arm 221 is spaced apart from the groove wall of the slide groove 12 on the side away from the cover flange 21, that is, the second connecting section 2212 has a movable space on the side away from the cover flange 21 to ensure the connection and separation of the quick-release structure 22 and the latch 13, thereby improving the connection reliability and disassembly convenience of the shell 10 and the cover body 20. When a through hole is provided on the side of the slide groove 12 facing the accommodating space 101, the groove wall is the surface where the edge of the through hole is located, and when the slide groove 12 is provided with a groove bottom opposite to the first notch 121, the groove wall is the groove bottom of the slide groove 12.

[0059] Optionally, in one embodiment of the present invention, a through hole is provided on the side of the slide groove 12 facing the accommodating space 101. At this time, the slide groove 12 passes through the frame edge 11 and connects to the accommodating space 101, which can not only reduce the overall weight of the shell 10, but also serve as a heat dissipation hole to improve the heat dissipation effect.

[0060] In one embodiment of the present invention, the chute 12 is provided with a chute bottom opposite to the first notch 121 . In this case, the chute 12 is a blind chute, and the configuration of the chute bottom can be used to enhance the structural stability of the chute 12 .

[0061] See also Figure 5 In an embodiment of the present invention, a first guide slope 131 is provided on the side of the latching protrusion 13 facing the catch protrusion 222 to guide the latching protrusion 13 out of the receiving groove 23. It is understood that when the cover 20 and the housing 10 need to be separated, force is applied to the tablet computer protective cover, causing the cover 20 to slide along the extension direction of the frame edge 11. At this time, the quick-release structure 22 and the latching protrusion 13 have a tendency to separate, and the catch protrusion 222 abuts the latching protrusion 13. Under the action of the first guide slope 131, the catch protrusion 222 gradually moves upward until it separates from the latch protrusion 13. During this process, the spacing between the connecting arm 221 and the sidewall of the slide groove 12 provides space for the connecting arm 221 to move upward or deform. The first guide slope 131 is inclined toward the first notch 121 while extending toward the receiving space 101.

[0062] Specifically, in an embodiment of the present invention, the buckle protrusion 222 is provided with a matching bevel 2221 adapted to the first guide bevel 131. At this time, the matching bevel 2221 is parallel to the first guide bevel 131. On the one hand, it can increase the connection area between the buckle protrusion 222 and the connecting arm 221 and improve the connection strength between the buckle protrusion 222 and the connecting arm 221. On the other hand, when the locking protrusion 13 is clamped in the accommodating groove 23, the matching bevel 2221 is fitted with the first guide bevel 131 to increase the connection area between the locking protrusion 13 and the connecting arm 221, and to enhance the ability of the buckle protrusion 222 to stop the locking protrusion 13 from escaping from the opening 231 to a certain extent. When the cover body 20 and the shell body 10 need to be separated, the fitting and relative movement between the matching bevel 2221 and the first guide bevel 131 can reduce the possibility of deformation of the connecting arm 221.

[0063] Specifically, in an embodiment of the present invention, a second guiding slope 2222 is provided on the side of the buckle protrusion 222 away from the locking protrusion 13, for assisting the locking protrusion 13 to pass through the opening 231. At this time, the second guiding slope 2222 is inclined in the direction away from the first slot 121 while extending toward the accommodating space 101, so that the buckle protrusion 222 is gradually contracted in the direction close to the cover flange 21, which facilitates the deformation of the buckle protrusion 222; and when it is necessary to connect the cover body 20 and the shell 10, the quick-release structure 22 first abuts the locking protrusion 13 with the second guiding slope 2222. When force is continued to be applied, the locking protrusion 13 moves downward along the second guiding slope 2222, and cooperates with the deformable characteristics of the connecting arm 221 to enter the accommodating groove 23 through the opening 231.

[0064] See also Figures 1 to 7 In one embodiment of the present invention, the tablet computer protective cover includes a shell 10 and a cover 20; the shell 10 is provided with a storage space 101 for accommodating the tablet computer, the shell 10 has a frame edge 11, and the frame edge 11 is provided with at least two slide grooves 12 along its extension direction, the slide groove 12 is connected to the storage space 101, and a first notch 121 and a second notch 122 are formed on the side of the slide groove 12 away from the storage space 101, and a locking protrusion 13 is formed between the first notch 121 and the second notch 122; the cover 20 includes a cover flange 21, and the cover flange 21 is provided with at least two quick-release structures 22 corresponding to the positions of the slide grooves 12, and the quick-release structure 22 includes a connecting arm 221 and a buckle protrusion 222 protruding from the cover flange 21. One end of the connecting arm 221 is connected to the cover flange 21, and a receiving groove 23 is formed between the connecting arm 221 and the cover flange 21. The other end of the connecting arm 221 is connected to the buckle protrusion 222 toward one side of the cover flange 21, and an opening 231 is formed between the buckle protrusion 222 and the cover flange 21; wherein, the first notch 121 is used for the quick-release structure 22 to extend into the slide groove 12; when the quick-release structure 22 extends into the slide groove 12, and after the cover body 20 and the shell 10 move relative to each other, the locking protrusion 13 passes through the opening 231 and is locked in the receiving groove 23; in this way, the convenience of disassembly and assembly of the shell 10 and the cover body 20 can be improved, thereby quickly reducing the weight of the tablet computer protective cover, making it more convenient for users to hold, and improving the user experience.

[0065] In the technical solution of the present invention, a slide groove 12 is provided on the frame edge 11 of the shell 10, and a locking protrusion 13 is provided in the annular groove. A first notch 121 is provided on the side of the slide groove 12 away from the accommodating space 101, and a quick-release structure 22 is provided on the cover flange 21 of the cover body 20. An opening 231 is formed between the quick-release structure 22 and the cover flange 21 to face the accommodating groove 23 of the locking protrusion 13. Then, the quick-release structure 22 can extend into the slide groove 12 through the first notch 121, and after the cover body 20 and the shell 10 move relative to each other, the locking protrusion 13 is locked in the accommodating groove 23, completing the work. The assembly of the cover body 20 and the shell 10 can not only ensure the connection strength of the cover body 20 and the shell 10, but also effectively protect the tablet computer built into the accommodating space 101; and benefiting from the snap-fitting of the quick-release structure 22 and the latch 13, the relative sliding of the cover body 20 and the shell 10 can make the quick-release structure 22 slide along the slide groove 12 toward the first notch 121 and quickly separate from the latch 13, thereby improving the convenience of disassembly and assembly of the shell 10 and the cover body 20, and further, helping to quickly reduce the weight of the tablet computer protective cover, making it more convenient for users to hold, and improving the user experience.

[0066] At least two quick-release structures 22 are provided on the cover flange 21. At this time, a slide groove 12 and a latching protrusion 13 provided in the slide groove 12 are correspondingly provided on the frame edge 11. Furthermore, when the cover body 20 and the shell 10 are snap-fitted through the quick-release structure 22 and the latching protrusion 13, it is beneficial to improve the connection strength between the cover body 20 and the shell 10 and ensure a stable connection between the cover body 20 and the shell 10.

[0067] Specifically, the chute 12 extends along the extension direction of the frame edge 11 to provide guidance for the quick-release structure 22 to slide within the chute 12. The first notch 121, located away from the latching protrusion 13, forms the starting end of the chute 12, ensuring that the quick-release structure 22 can translate toward the latching protrusion 13. The latching protrusion 13 is connected between opposing walls of the chute 12, extending along the thickness direction of the frame edge 11, thereby securing the latching protrusion 13 and the quick-release structure 22. The latching protrusion 13 can be formed in the frame edge 11 by stamping, integral molding, or other methods. The second notch 122, located away from the latching protrusion 13, forms the terminating end of the chute 12. This not only constrains further movement of the quick-release structure 22 but also extends the chute 12, allowing the portion of the chute 12 corresponding to the second notch 122 to accommodate the latching protrusion 222 and a portion of the connecting arm 221, thus securing the quick-release structure 22 to the latching protrusion 13.

[0068] Furthermore, when the latching protrusion 13 is inserted into the receiving slot 23, the latching protrusion 222 is exposed at the second notch 122. Furthermore, when the side of the slide slot 12 facing the receiving space 101 is provided with a through hole, the outlet area of the slide slot 12 is increased, thereby facilitating heat dissipation for the tablet computer. However, in other embodiments, the slide slot 12 does not have the second notch 122.

[0069] The quick-release structure 22 includes a connecting arm 221 and a buckle protrusion 222. The connecting arm 221 is protruded from the side of the cover flange 21 facing the frame edge 11, so that after the connecting arm 221 extends into the slide groove 12, the cover flange 21 can fit with the frame edge 11, thereby increasing the effective contact area between the cover body 20 and the shell 10, and improving the connection stability between the cover body 20 and the shell 10; after the latching protrusion 13 is latched in the receiving groove 23, because the buckle protrusion 222 is protruded from the side of the connecting arm 221 facing the cover flange 21, an opening 231 connected to the receiving groove 23 is formed, the buckle protrusion 222 can effectively prevent the latching protrusion 13 from escaping from the receiving groove 23, and can also reduce the shaking of the latching protrusion 13 in the receiving groove 23 to a certain extent, further strengthening the connection stability between the cover body 20 and the shell 10. The quick-release structure 22 and the cover flange 21 can be fixed into a whole by, for example, injection molding. The manufacturing material of the quick-release structure 22 can be a flexible structure such as soft rubber, so that the quick-release structure 22 has a deformable property to achieve rapid connection and separation of the quick-release structure 22 and the locking protrusion 13.

[0070] like Figure 5 As shown, in an embodiment of the present invention, the connecting arm 221 includes a first connecting segment 2211 and a second connecting segment 2212, one end of the first connecting segment 2211 is connected to the cover flange 21, and the side of the second connecting segment 2212 facing the cover flange 21 is connected to the other end of the first connecting segment 2211 and the buckle protrusion 222; in this way, it is convenient to form a receiving groove 23 and an opening 231 between the connecting arm 221 and the cover flange 21.

[0071] Among them, in the extension direction of the frame edge 11, the width of the second connecting section 2212 is smaller than the width of the first slot 121, that is, the width of the second connecting section 2212 is smaller than the width of the first slot 121. When the quick-release structure 22 is moved toward the first slot 121, the quick-release structure 22 can smoothly pass through the first slot 121 and extend into the slide groove 12, or smoothly detach from the slide groove 12 from the first slot 121, thereby improving the convenience of disassembly and assembly of the cover body 20 and the shell body 10.

[0072] Moreover, when the latching protrusion 13 is locked in the accommodating groove 23, the other end of the connecting arm 221 is spaced apart from the groove wall of the slide groove 12, that is, the second connecting section 2212 is spaced apart from the groove side wall of the slide groove 12, which can not only prevent the connecting arm 221 from hitting the groove wall of the slide groove 12, but also provide deformation space when the connecting arm 221 needs to be deformed, thereby improving the connection reliability and disassembly convenience of the shell 10 and the cover body 20. At the same time, the connecting arm 221 is spaced apart from the groove wall of the slide groove 12 on the side away from the cover flange 21, that is, the second connecting section 2212 has a movable space on the side away from the cover flange 21 to ensure the connection and separation of the quick-release structure 22 and the latch 13, thereby improving the connection reliability and disassembly convenience of the shell 10 and the cover body 20. When a through hole is provided on the side of the slide groove 12 facing the accommodating space 101, the groove wall is the surface where the edge of the through hole is located, and when the slide groove 12 is provided with a groove bottom opposite to the first notch 121, the groove wall is the groove bottom of the slide groove 12.

[0073] like Figures 1 to 3 As shown, the cover 20 is provided with a plurality of folds that can be used to fold the cover 20 into a supporting portion. Preferably, two folds are evenly arranged so that the cover 20 can be folded into a three-dimensional triangle after being flipped open. Figure 1 and Figure 2 The shell 10 and the tablet computer are stably supported, wherein the at least two slide grooves 12 are provided on the two adjacent frame edges 11 of the shell 10, and the two adjacent frame edges 11 can be selectively connected to the cover flange 21 through the snap-fit cooperation of the card protrusion 13 and the quick-release structure 22 to realize the horizontal and vertical switching of the shell 10. It can be understood that the accommodating space 101 is formed by the bottom plate of the shell 10 and the multiple frame edges 11 arranged along the periphery of the bottom plate. In order to meet the user's needs of placing the tablet computer horizontally or vertically, at least two slide grooves 12 are provided on the two adjacent frame edges 11, and a card protrusion 13 is provided in the slide groove 12. In this way, when the tablet computer is placed horizontally or vertically, the shell 10 can provide the corresponding card protrusion 13 on the frame edge 11 to be connected to the quick-release structure 22 on the cover flange 21, thereby improving the placement stability of the tablet computer.

[0074] In addition, providing the slide grooves 12 and the corresponding latching protrusions 13 on the multiple frame edges 11 can reduce the overall weight of the shell 10 to a certain extent and ensure the structural stability of the slide grooves 12. Moreover, when the side of the slide groove 12 facing the accommodating space 101 is provided as a through hole, the idle slide groove 12 can serve as a heat dissipation hole to facilitate the heat dissipation of the tablet computer.

[0075] Furthermore, in an embodiment of the present invention, in the extension direction of the frame edge 11, the width of the second notch 122 is smaller than the width of the first notch 121, which can avoid the distance between the terminal end of the slide groove 12 and the card protrusion 13 being too large, and facilitate the connection between the quick-release structure 22 and the card protrusion 13 within the limited slide groove 12, while ensuring the structural stability of the frame edge 11; and it can also reduce the space for relative movement between the quick-release structure 22 and the card protrusion 13, thereby reducing shaking.

[0076] See also Figure 5 In the embodiment of the present invention, a first guide slope 131 is provided on the side of the latching protrusion 13 facing the buckle protrusion 222. The buckle protrusion 222 is provided with a matching bevel 2221 that matches the first guide slope 131. It is understood that when the cover 20 and the housing 10 need to be separated, force is applied to the tablet computer protective cover, causing the cover 20 to slide along the extension direction of the frame edge 11. At this time, the quick-release structure 22 and the latching protrusion 13 have a tendency to separate. The buckle protrusion 222 abuts the latching protrusion 13. Under the action of the first guide slope 131, the buckle protrusion 222 gradually moves upward until it separates from the latching protrusion 13. During this process, the spacing between the connecting arm 221 and the sidewall of the slide groove 12 provides space for the connecting arm 221 to move upward or deform. The first guide slope 131 is inclined toward the first notch 121 while extending toward the accommodating space 101.

[0077] During this process, the mating bevel 2221 is parallel to the first guide bevel 131. On the one hand, it can increase the connection area between the buckle protrusion 222 and the connecting arm 221 and improve the connection strength between the buckle protrusion 222 and the connecting arm 221. On the other hand, when the locking protrusion 13 is clamped in the accommodating groove 23, the mating bevel 2221 is fitted with the first guide bevel 131 to increase the connection area between the locking protrusion 13 and the connecting arm 221, which can enhance the ability of the buckle protrusion 222 to stop the locking protrusion 13 from escaping from the opening 231 to a certain extent. When the cover body 20 and the shell body 10 need to be separated, the fitting and relative movement between the mating bevel 2221 and the first guide bevel 131 can reduce the possibility of deformation of the connecting arm 221.

[0078] Specifically, in an embodiment of the present invention, a second guiding slope 2222 is provided on the side of the buckle protrusion 222 away from the locking protrusion 13, for assisting the locking protrusion 13 to pass through the opening 231. At this time, the second guiding slope 2222 is inclined in the direction away from the first slot 121 while extending toward the accommodating space 101, so that the buckle protrusion 222 is gradually contracted in the direction close to the cover flange 21, which facilitates the deformation of the buckle protrusion 222; and when it is necessary to connect the cover body 20 and the shell 10, the quick-release structure 22 first abuts the locking protrusion 13 with the second guiding slope 2222. When force is continued to be applied, the locking protrusion 13 moves downward along the second guiding slope 2222, and cooperates with the deformable characteristics of the connecting arm 221 to enter the accommodating groove 23 through the opening 231.

[0079] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
