[0001] The present application relates to the technical field of electronic products, and in particular to a protective shell, an electronic device and an electronic device kit. Background Art

[0002] Currently, protective cases (such as leather cases, etc.) of existing electronic devices are usually connected to the electronic devices by means of magnetism, glue, or adding external buckles to the electronic devices.

[0003] However, the magnetic method is difficult to ensure the reliability of the connection between the protective case and the electronic device, the adhesive method affects the appearance of the electronic device and is difficult to replace, and adding external buckles to the electronic device will undoubtedly have a greater impact on the feel of the electronic device. In view of this, how to improve the connection reliability and replacement convenience while achieving the connection between the protective case and the electronic device, and minimize the impact on the appearance and feel of the electronic device in order to achieve the connection, has become an urgent problem to be solved. Utility Model Content

[0004] The main technical problem solved by the present application is to provide a protective case, an electronic device and an electronic device kit, which can improve the connection reliability and replacement convenience while realizing the connection between the protective case and the electronic device, and minimize the impact on the appearance and feel of the electronic device caused by realizing the connection between them.

[0005] In order to solve the above-mentioned technical problems, the first aspect of the present application provides a protective shell, including: a protective shell body, a rotating shaft and a first buckle, the rotating shaft is connected to the protective shell body, and the protective shell body flips around the rotating shaft to at least cover the display screen of the electronic device; the first buckle is movably connected to the rotating shaft along the extension direction of the rotating shaft, the first buckle is used to extend into a hole opened in the electronic device, a second buckle matching the first buckle is provided in the hole inside the electronic device, and the first buckle is pushed along the extension direction to match or cancel the connection with the second buckle.

[0006] Therefore, the protective case includes a protective case body, a rotating shaft, and a first buckle. The rotating shaft is connected to the protective case body, and the protective case body rotates around the rotating shaft for at least covering the display screen of the electronic device. The first buckle is movably connected to the rotating shaft along the extending direction of the rotating shaft. The first buckle is used to extend into a hole of the electronic device. A second buckle matching the first buckle is provided in the hole inside the electronic device. The first buckle is pushed along the extending direction to be matched and connected or disconnected from the second buckle. Therefore, on the one hand, through the mutual cooperation between the first buckle and the second buckle, the connection between the protective case and the electronic device can be realized. On the other hand, compared with magnetic connection, the connection by buckles can improve the connection reliability. On the further hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device to realize the connection, but adding buckles inside the electronic device helps to minimize the impact on the appearance and feel of the electronic device caused by realizing the connection between each other. And since the first buckle can be matched and connected or cooperatively connected with the second buckle when pushed along the extending direction, the replacement convenience of the protective case can be improved. Therefore, it is possible to improve the connection reliability and replacement convenience on the premise of realizing the connection between the protective case and the electronic device, and minimize the impact on the appearance and feel of the electronic device caused by realizing the connection between each other.

[0007] Among them, the second buckle at least includes a leaf spring. The leaf spring is provided with a protrusion, and the first buckle is provided with a depression matching the protrusion on the buckle end face facing the leaf spring.

[0008] Therefore, the second buckle at least includes a leaf spring. The leaf spring is provided with a protrusion, and the first buckle is provided with a depression matching the protrusion on the buckle end face facing the leaf spring. Therefore, it is possible to utilize the protrusion on the leaf spring, its own elastic characteristics, and the depression to achieve mutual cooperation, which helps to minimize the driving force required to push the first buckle to be matched and connected or disconnected from the second buckle.

[0009] Among them, the hole is opened on the side wall of the electronic device adjacent to the display screen, and the extending direction of the protrusion is parallel to the extending direction of the depression, and both the extending direction of the protrusion and the extending direction of the depression intersect the side wall.

[0010] Therefore, the hole is opened on the side wall of the electronic device adjacent to the display screen, and the extending direction of the protrusion is parallel to the extending direction of the depression, and both the extending direction of the protrusion and the extending direction of the depression intersect the side wall. Therefore, compared with opening holes on other walls of the electronic device, opening holes on the side wall can, on the one hand, minimize the impact on the appearance of the electronic device caused by opening the holes, and on the other hand, can also facilitate the extension of the first buckle as much as possible, which helps to improve the installation or replacement convenience of the protective case.

[0011] Among them, the extending directions of the protrusion and the depression are both perpendicular to the side wall.

[0012] Therefore, the extending directions of both the protrusion and the depression are perpendicular to the side wall, which can improve the connection strength between the protrusion and the depression as much as possible.

[0013] The protective shell includes a plurality of first buckles respectively used for extending into different holes formed in the side wall. The electronic device is respectively provided with second buckles in different holes, and each first buckle is pushed along the extending direction to be matched and connected or disconnected with the corresponding second buckle.

[0014] Therefore, by providing a plurality of first buckles on the protective shell to achieve matching connection or disconnection with a plurality of second buckles correspondingly provided on the electronic device, the connection strength between the protective shell and the electronic device can be improved as much as possible.

[0015] To solve the above technical problems, a second aspect of the present application provides an electronic device, including: a display screen, holes, and second buckles. The holes are used for the first buckles of the protective shell to extend into. The protective shell body of the protective shell rotates around the rotating shaft of the protective shell and is used to at least cover the display screen. The first buckles are movably connected to the rotating shaft along the extending direction of the rotating shaft; the second buckles are arranged in the holes inside the electronic device, the second buckles are matched with the first buckles, and the first buckles are pushed along the extending direction to be matched and connected or disconnected with the second buckles.

[0016] Therefore, the electronic device includes a display screen, holes, and second buckles. The holes are used for the first buckles of the protective shell to extend into. The protective shell body of the protective shell rotates around the rotating shaft of the protective shell and is used to at least cover the display screen. The first buckles are movably connected to the rotating shaft along the extending direction of the rotating shaft. The second buckles are arranged in the holes inside the electronic device, the second buckles are matched with the first buckles, and the first buckles are pushed along the extending direction to be matched and connected or disconnected with the second buckles. Therefore, on the one hand, through the mutual cooperation between the first buckles and the second buckles, the connection between the protective shell and the electronic device can be realized. On the other hand, compared with magnetic connection, the connection reliability can be improved by using buckles. On the other hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device to achieve connection, but adding buckles inside the electronic device helps to reduce the impact on the appearance and feel of the electronic device caused by achieving mutual connection as much as possible. And since the first buckles can be matched and connected or cooperatively connected with the second buckles when pushed along the extending direction, the replacement convenience of the protective shell can be improved. Therefore, on the premise of realizing the connection between the protective shell and the electronic device, the connection reliability and replacement convenience can be improved, and the impact on the appearance and feel of the electronic device caused by achieving mutual connection can be reduced as much as possible.

[0017] Among them, the second buckle at least includes a leaf spring. The leaf spring is provided with a protrusion, and the first buckle is provided with a depression matching the protrusion on the buckle end face facing the leaf spring.

[0018] Therefore, the second buckle at least includes a leaf spring, the leaf spring is provided with a protrusion, and the first buckle is provided with a recess matching the protrusion on the buckle end face facing the leaf spring. Therefore, the protrusion on the leaf spring can be matched with its own elastic characteristics and the recess to realize mutual cooperation, which helps to minimize the driving force required to push the first buckle to match or disconnect from the second buckle.

[0019] Among them, the hole is opened on the side wall of the electronic device adjacent to the display screen, the extending direction of the protrusion is parallel to the extending direction of the recess, and both the extending direction of the protrusion and the extending direction of the recess intersect the side wall.

[0020] Therefore, the hole is opened on the side wall of the electronic device adjacent to the display screen, the extending direction of the protrusion is parallel to the extending direction of the recess, and both the extending direction of the protrusion and the extending direction of the recess intersect the side wall. Therefore, compared with opening holes on other walls of the electronic device, opening holes on the side wall can, on the one hand, minimize the impact on the appearance of the electronic device caused by opening the holes, and on the other hand, can also facilitate the insertion of the first buckle as much as possible, which helps to improve the convenience of installing or replacing the protective case.

[0021] Among them, the second buckle further includes fixing members provided at both ends of the leaf spring for fixing the leaf spring.

[0022] Therefore, the second buckle further includes fixing members provided at both ends of the leaf spring for fixing the leaf spring, which can improve the bonding force between the second buckle and the electronic device body as much as possible, help to improve the connection strength between the first buckle and the second buckle, and further improve the connection strength between the protective case and the electronic device.

[0023] To solve the above technical problems, a third aspect of the present application provides an electronic device kit, including the protective case in the first aspect and the electronic device in the second aspect.

[0024] Therefore, on the one hand, through the mutual cooperation between the first buckle and the second buckle, the protective case and the electronic device can be connected to each other. On the other hand, compared with magnetic attraction connection, the connection reliability can be improved by using buckles for mating connection. On the other hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device to achieve connection, but adding buckles inside the electronic device can help to minimize the impact on the appearance and feel of the electronic device caused by achieving mutual connection. And since the first buckle can be matched or connected with the second buckle when pushed along the extending direction, the replacement convenience of the protective case can be improved. Therefore, on the premise of realizing the connection between the protective case and the electronic device, the connection reliability and replacement convenience can be improved, and the impact on the appearance and feel of the electronic device caused by achieving mutual connection can be minimized.

[0029] The following will combine the accompanying drawings of the specification to elaborate in detail on the solutions of the embodiments of the present application.

[0030] In the following description, specific details such as specific system structures, interfaces, and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the present application.

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , Figure 1 is a schematic structural diagram of an embodiment of the protective case and the electronic device of the present application, Figure 2 is a schematic structural diagram of another embodiment of the protective case and the electronic device of the present application, Figure 3 is a schematic structural diagram of yet another embodiment of the protective case and the electronic device of the present application, Figure 4 is a schematic structural diagram of yet another embodiment of the protective case and the electronic device of the present application. As Figures 1 to 4As shown in the figure, the protective case 10 of the present application includes a protective case body 11, a rotating shaft 12, and a first buckle 13. The rotating shaft 12 is connected to the protective case body 11, and the protective case body 11 rotates around the rotating shaft 12 for at least covering the display screen 21 of the electronic device 20. The first buckle 13 is movably connected to the rotating shaft 12 along the extension direction of the rotating shaft 12 (as shown by the double-headed arrow in the figure). The first buckle 13 is used to extend into the hole 22 opened in the electronic device 20. A second buckle 23 matching the first buckle 13 is provided inside the electronic device 20 at the hole 22, and the first buckle 13 is pushed along the extension direction to be matched and connected or disconnected from the second buckle 23.

[0033] In one implementation scenario, the protective case 10 can be made of at least one of leather, plastic, and metal, and no limitation is made here. As a possible example, the protective case body 11 of the protective case 10 can be made of leather, the rotating shaft 12 of the protective case 10 can be made of metal, and the first buckle 13 of the protective case 10 can be made of plastic, and no limitation is made here.

[0034] In one implementation scenario, the electronic device 20 can include, but is not limited to, an office notebook, a learning machine, a tablet computer, etc., and no specific type of the electronic device 20 is limited here. In addition, the display screen 21 of the electronic device 20 can include, but is not limited to, an e-ink screen, an LCD screen, an OLED screen, etc., and no specific type of the display screen 21 is limited here.

[0035] In one implementation scenario, the first buckle 13 and the second buckle 23 can include, but are not limited to, a hook-shaped cantilever buckle, a sleeve-shaped cantilever buckle, a special-shaped cantilever buckle, a circular buckle, etc., and no limitation is made on the buckle types of the first buckle 13 and the second buckle 23 here.

[0036] In one implementation scenario, the electronic device 20 can open the hole 22 on the side wall adjacent to the display screen 21 (not shown). Alternatively, the electronic device 20 can also open the hole 22 on the side opposite to the display screen 21 (not shown), and no limitation is made here. Preferably, in order to minimize the impact of opening the hole 22 on the appearance of the electronic device 20 as much as possible, the hole 22 can be opened on the side wall of the electronic device 20 adjacent to the display screen 21.

[0037] In an implementation scenario, the size and shape of the hole 22 may specifically be such that the first buckle 13 can freely extend into and out of it, and the size and shape of the hole 22 are not limited herein. In addition, to facilitate the movable connection of the first buckle 13 to the rotating shaft 12 along the extending direction of the rotating shaft 12, the rotating shaft 12 may be provided with a through hole (not shown) along its extending direction, and the first buckle 13 may be movably connected to the through hole. In addition, the size of the through hole may be set according to the pushing stroke of the first buckle 13 relative to the second buckle 23. Specifically, the size of the through hole in the extending direction of the rotating shaft 12 should be not less than the pushing stroke of the first buckle 13 relative to the second buckle 23, so as to minimize the influence of the through hole on the free pushing of the first buckle 13 relative to the second buckle 23.

[0038] In an implementation scenario, the extending direction of the rotating shaft 12 may be expressed as that the middle part of the rotating shaft 12 extends to the two ends of the rotating shaft 12 respectively. Then, when the first buckle 13 is pushed along one of the extending directions of the rotating shaft 12, the first buckle 13 is matingly connected to the second buckle 23. On the contrary, when the first buckle 13 is pushed along the other extending direction of the rotating shaft 12, the connection between the first buckle 13 and the second buckle 23 is cancelled.

[0039] In an implementation scenario, as a possible example, the second buckle 23 may at least include a leaf spring 231. The leaf spring 231 may be provided with a protrusion A, and the first buckle 13 is provided with a depression B on the buckle end face (not shown) facing the leaf spring 231 that matches the protrusion A. That is to say, during the process of pushing the first buckle 13 along one of the extending directions, when the depression B of the first buckle 13 has not reached the protrusion A, the protrusion A is elastically deformed by the abutment of the first buckle 13, that is, deformed in a direction away from the buckle end face of the first buckle 13. When the depression B reaches the protrusion A, the protrusion A resumes its deformation, that is, deforms in a direction closer to the buckle end face of the first buckle 13 until the depression B is completely aligned with the protrusion A. At this time, the protrusion A is accommodated in the depression B, and the first buckle 13 is matingly connected to the second buckle 23. On the contrary, during the process of pushing the first buckle 13 along the other extending direction, the depression B of the first buckle 13 is gradually misaligned with the protrusion A, and the protrusion A is elastically deformed by the abutment of the first buckle 13, that is, deformed in a direction away from the buckle end face of the first buckle 13 until the depression B travels to be completely misaligned with the protrusion A. At this time, the protrusion A resumes its deformation, and the connection between the first buckle 13 and the second buckle 23 is cancelled.

[0040] In a specific implementation scenario, as described above, the hole 22 can be formed on the side wall of the electronic device 20 adjacent to the display screen 21. In addition, the extending direction (not shown) of the protrusion A can be parallel to the extending direction (not shown) of the recess B, and both the extending direction of the protrusion A and the extending direction of the recess B are relative to the side wall. That is to say, the protrusion A can be set in a ridge shape, and the recess B can be set in a groove shape, and their extending directions can be set to be the same, so as to achieve a matching connection between the first buckle 13 and the second buckle 23 when they are aligned, and when they are misaligned, the connection between the first buckle 13 and the second buckle 23 is cancelled. Preferably, when the protrusion A is set in a ridge shape and the recess B is set in a groove shape, the extending directions of the protrusion A and the recess B can both be set perpendicular to the side wall of the electronic device 20 where the hole 22 is formed.

[0041] In a specific implementation scenario, different from the foregoing manner, the protrusion A and the recess B can also be set as hemispherical. The difference is that the protrusion A can be set as a hemispherical shape protruding from the surface of the leaf spring 231 towards the first buckle 13, and the recess B can be set as concave in the buckle end face of the first buckle 13 facing the leaf spring 231.

[0042] It should be noted that the above examples are only several possible examples of the protrusion A and the recess B, and do not limit the setting manners of the protrusion A and the recess B accordingly. Specifically, it is appropriate that the protrusion A and the recess B can be aligned or misaligned with each other under the action of a thrust force, and no further examples will be given here.

[0043] In an implementation scenario, the protective case 10 can include a plurality of first buckles 13, which are respectively used to extend into different holes 22 formed in the electronic device 20 (for example, they can all be formed in the aforementioned side wall). The electronic device 20 is respectively provided with second buckles 23 at different holes 22. Each first buckle 13 is pushed along the extending direction of the rotating shaft 12 to be matched and connected or disconnected with the corresponding first buckle 13, so as to improve the connection reliability between the protective case 10 and the electronic device 20 through the mutual cooperation between multiple groups of first buckles 13 and second buckles 23. It should be noted that in the case of setting a plurality of first buckles 13 and the corresponding second buckles 23, the specific number of groups of the first buckles 13 and the second buckles 23 is not limited here. Exemplarily, two groups of first buckles 13 and second buckles 23 can be set, or three groups of first buckles 13 and second buckles 23 can be set, or four groups of first buckles 13 and second buckles 23 can be set. Of course, the above examples are only several possible examples of the specific number of groups of the first buckles 13 and the second buckles 23, and the specific number of groups of the first buckles 13 and the second buckles 23 is not limited here.

[0044] In the above solution, the protective case 10 includes a protective case body 11, a rotating shaft 12, and a first buckle 13. The rotating shaft 12 is connected to the protective case body 11. The protective case body 11 rotates around the rotating shaft 12 and is used to at least cover the display screen 21 of the electronic device 20. The first buckle 13 is movably connected to the rotating shaft 12 along the extending direction of the rotating shaft 12. The first buckle 13 is used to extend into the hole 22 of the electronic device 20. A second buckle 23 matching the first buckle 13 is provided inside the electronic device 20 at the hole 22. The first buckle 13 is pushed along the extending direction to be matched and connected or disconnected from the second buckle 23. Therefore, on the one hand, through the mutual cooperation between the first buckle 13 and the second buckle 23, the connection between the protective case 10 and the electronic device 20 can be realized. On the other hand, compared with magnetic connection, the connection is realized through buckles, which can improve the connection reliability. On the other hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device 20 to realize the connection, but adding buckles inside the electronic device 20 helps to minimize the impact on the appearance and feel of the electronic device 20 caused by realizing the connection between each other. And since the first buckle 13 can be matched and connected or cooperatively connected with the second buckle 23 when pushed along the extending direction, the replacement convenience of the protective case 10 can be improved. Therefore, on the premise of realizing the connection between the protective case 10 and the electronic device 20, the connection reliability and replacement convenience can be improved, and the impact on the appearance and feel of the electronic device 20 caused by realizing the connection between each other can be minimized as much as possible.

[0045] Please continue to refer to Figures 1 to 4 , the electronic device 20 of the present application may include a display screen 21, a hole 22, and a second buckle 23. The hole 22 is used for the first buckle 13 of the protective case 10 to extend into. The protective case body 11 of the protective case 10 rotates around the rotating shaft 12 of the protective case 10 and is used to at least cover the display screen 21. The first buckle 13 is movably connected to the rotating shaft 12 along the extending direction of the rotating shaft 12 (as shown by the double-headed arrow in the figure); the second buckle 23 is provided inside the electronic device 20 at the hole 22. The second buckle 23 matches the first buckle 13. The first buckle 13 is pushed along the extending direction to be matched and connected or disconnected from the second buckle 23. For the same or similar parts, specific reference can be made to the relevant description of the protective case 10 above, and details will not be repeated here. The following mainly describes the parts not mentioned above.

[0046] In an implementation scenario, as described above, the second buckle 23 may specifically include a leaf spring 231 to utilize the protrusion A on the leaf spring 231, its own elastic characteristics, and the recess B on the first buckle 13 to achieve mutual cooperation, which helps to minimize the driving force required to push the first buckle 13 to achieve mating connection or disconnection with the second buckle 23. In addition, the second buckle 23 may further include fixing members 232 provided at both ends of the leaf spring 231. It should be noted that the fixing members 232 may include, but are not limited to: screws, dispensing, etc., and the specific types of the fixing members 232 are not limited herein.

[0047] In an implementation scenario, the second buckle 23 may specifically be disposed inside the electronic device 20 near the hole 22. Specifically, it is preferably set according to the depth of the first buckle 13 extending into the hole 22. Taking the example that the hole 22 is disposed on the side wall adjacent to the display screen 21, the distance from the second buckle 23 to the inner wall of the side wall may be set to match the distance from the inner wall of the side wall where the first buckle 13 extends out after extending into the hole 22. For example, the distance from the second buckle to the inner wall of the side wall may specifically be consistent with the distance from the inner wall of the side wall where the first buckle 13 extends out.

[0048] In an implementation scenario, the second buckle 23 may further include a stop strip 233 disposed on the side of the leaf spring 231 away from the hole 22, and the stop strip 233 abuts against the leaf spring 231 to minimize the possibility of the leaf spring 231 deviating relative to the hole 22 during use.

[0049] In the above solution, the electronic device 20 includes a display screen 21, a hole 22, and a second buckle 23. The hole 22 is for the first buckle 13 of the protective case 10 to extend into. The protective case body 11 of the protective case 10 rotates around the rotating shaft 12 of the protective case 10 to at least cover the display screen 21. The first buckle 13 is movably connected to the rotating shaft 12 along the extension direction of the rotating shaft 12. The second buckle 23 is disposed inside the electronic device 20 at the hole 22. The second buckle 23 matches the first buckle 13. The first buckle 13 is pushed along the extension direction to be matched and connected or disconnected from the second buckle 23. Therefore, on the one hand, through the mutual cooperation between the first buckle 13 and the second buckle 23, the connection between the protective case 10 and the electronic device 20 can be realized. On the other hand, compared with magnetic connection, the connection is realized through buckles, which can improve the connection reliability. On the other hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device 20 to realize the connection, but adding buckles inside the electronic device 20 helps to minimize the impact on the appearance and feel of the electronic device 20 for realizing the connection. And since the first buckle 13 can be matched and connected or cooperatively connected with the second buckle 23 when pushed along the extension direction, the replacement convenience of the protective case 10 can be improved. Therefore, on the premise of realizing the connection between the protective case 10 and the electronic device 20, the connection reliability and replacement convenience can be improved, and the impact on the appearance and feel of the electronic device 20 for realizing the connection can be minimized as much as possible.

[0050] Please continue to refer to Figures 1 to 4 , the electronic device kit 30 of the present application may include a protective case 10 and an electronic device 20. For the specific structures of the protective case 10 and the electronic device 20, reference may be made to the foregoing specific descriptions of the protective case 10 and the electronic device 20, which will not be elaborated here. It should be noted that the connection state between the protective case 10 and the electronic device 20 in the electronic device kit 30 may be that the first buckle 13 is matched and connected with the second buckle 23, or the first buckle 13 is disconnected from the second buckle 23. The connection state between the protective case 10 and the electronic device 20 in the electronic device kit 30 is not limited herein.

[0051] In the above - mentioned manner, on the one hand, through the mutual cooperation between the first buckle 13 and the second buckle 23, the connection between the protective case 10 and the electronic device 20 can be achieved. On the other hand, compared with magnetic connection, the connection by buckles can improve the connection reliability. On the one hand, compared with adhesive connection and adding external buckles, since there is no need to add cumbersome objects outside the electronic device 20 to achieve connection, but adding buckles inside the electronic device 20 helps to minimize the impact on the appearance and feel of the electronic device 20 for achieving mutual connection. And since the first buckle 13 can be matched or cooperatively connected with the second buckle 23 when pushed along the extending direction, the replacement convenience of the protective case 10 can be improved. Therefore, on the premise of achieving the connection between the protective case 10 and the electronic device 20, the connection reliability and replacement convenience can be improved, and the impact on the appearance and feel of the electronic device 20 for achieving mutual connection can be minimized as much as possible.
