[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] It should be noted that all directional indicators (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0012] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0013] Please see Figures 1 to 8 This utility model provides a protective shell 100, including a shell 10, a connector 12, and a locking structure 14. The shell 10 is used to cover the outside of an electronic device to protect it. The electronic device can be a mobile phone, tablet, or other portable electronic device. The connector 12 is located on one side of the shell 10 and is used to connect to external accessories. These external accessories can be support accessories (such as a bracket) for supporting the electronic device, protective accessories (such as a cover plate) for covering the screen of the electronic device, or input accessories (such as a keyboard / handwriting tablet) for inputting characters. The locking structure 14 is located on the connector 12, and the connector 12 is detachably connected to the shell 10 through the locking structure 14. The locking structure 14 has a locked state and an unlocked state. In the locked state, the connector 12 is connected to the shell 10 through the locking structure 14. In the unlocked state, the connector 12 can be detached from the shell 10.

[0014] The locking structure 14 and the housing 10 are provided with a first locking part 16 and a second locking part 18 that cooperate with each other. The locking structure 14 can move relative to the housing 10 to lock or unlock the first locking part 16 and the second locking part 18. When the first locking part 16 and the second locking part 18 are locked, the locking structure 14 is in a locked state, and the connector 12 is connected to the housing 10 through the locking structure 14. When the first locking part 16 and the second locking part 18 are unlocked, the locking structure 14 is in an unlocked state, and the connector 12 can be removed from the housing 10. After the connector 12 is removed from the housing 10, the external accessories connected to the connector 12 can be separated from the housing 10, avoiding the interference of external accessories with the user's use of electronic devices when they are not needed. Moreover, when the connector 12 is connected to the housing 10, the cooperation of the first locking part 16 and the second locking part 18 can play a certain limiting role, reducing the risk of external accessories separating from the housing 10 when they are needed.

[0015] In one embodiment, the locking structure 14 includes a slider 20 that slidably engages with the connector 12. The slider 20 has a first locking portion 16 located at one end of the slider 20 in its sliding direction and capable of sliding along with the slider 20. The housing 10 has a second locking portion 18 corresponding to the first locking portion 16. When the slider 20 slides towards the second locking portion 18, the first locking portion 16 and the second locking portion 18 can lock together. When the slider 20 slides away from the second locking portion 18, the first locking portion 16 and the second locking portion 18 can be released. Locking and unlocking are achieved by sliding the slider 20, simplifying the operation and overall structure of the locking structure 14 and reducing manufacturing and assembly difficulties. In other embodiments, the first locking portion 16 may also be located on the side of the slider 20 facing the housing 10.

[0016] In one embodiment, the first locking part 16 is a locking tongue provided on the slider 20, and the second locking part 18 is a lock hole provided on the housing. The slider 20 can slide relative to the housing 10 to allow the locking tongue to be inserted into or withdrawn from the lock hole. That is, when the slider 20 moves toward the lock hole, the locking tongue can be inserted into the lock hole, at which time the first locking part 16 and the second locking part 18 form a locking effect. When the slider 20 moves away from the lock hole, the locking tongue can be withdrawn from the lock hole, at which time the first locking part 16 and the second locking part 18 are released from the lock.

[0017] Understandably, the movement of the latch structure 14 relative to the housing 10 to allow the bolt to insert into or retract from the lock hole can refer to the latch structure 14 rotating relative to the housing 10, or it can refer to the latch structure 14 sliding relative to the housing 10, as long as the latch structure 14 can allow the bolt to insert into or retract from the lock hole when it moves relative to the housing 10.

[0018] In other embodiments, the locking structure 14 can also be a snap-fit ​​structure or a hook structure, for example, the first locking part 16 is a buckle body, and the second locking part 18 is a buckle hole. When the locking structure 14 moves relative to the housing 10, the buckle body can be engaged into or disengaged from the buckle hole. When the buckle body is engaged into the buckle hole, the first locking part 16 and the second locking part 18 form a locking effect. When the buckle body is disengaged from the buckle hole, the first locking part 16 and the second locking part 18 are released from the locking effect.

[0019] The connector 12 is provided with a first groove 22, which extends along the sliding direction of the slider 20, and the length of the first groove 22 is greater than the length of the slider 20. The slider 20 is slidably installed in the first groove 22, allowing the slider 20 to slide within the first groove 22. Installing the slider 20 in the first groove 22 not only guides the slider 20 to slide, but also enhances the compactness of the structure.

[0020] The first locking part 16 is a latch located at one end of the slider 20, and the second locking part 18 is a lock hole located on the housing 10, with the latch and lock hole positioned opposite each other. The end of the first slide groove 22 facing the lock hole has an opening 24, meaning one end of the first slide groove 22 penetrates the surface of the connector 12 near the lock hole, thus forming an opening 24 for the latch to pass through. During the sliding of the slider 20, the latch in the first slide groove 22 can be inserted into the lock hole through the opening 24, or the latch in the lock hole can be retracted into the first slide groove 22 through the opening 24, thus switching between a locked and unlocked state.

[0021] A recessed accommodating groove 26 is formed on the outer side of the housing 10. A portion of the connector 12 is located within the accommodating groove 26. A first sliding groove 22 is provided on the portion of the connector 12 located within the accommodating groove 26. A locking hole is provided on the inner wall of one end of the accommodating groove 26, and the other portion of the connector 12 is located outside the accommodating groove 26 for connection with external accessories. The accommodating groove 26 on the outer side of the housing 10 serves to conceal the locking structure 14 and enhance structural compactness. Furthermore, the accommodating groove 26 also provides a certain degree of restraint for the connector 12, enhancing the connection reliability between the connector 12 and the housing 10 in the connected state.

[0022] In other embodiments, a protrusion can be provided on the outside of the housing 10, with the protrusion located at one end of the connector 12, and a locking hole provided on the protrusion for the insertion of the locking tongue. The connector 12 is detachably connected to the protrusion through the locking structure 14, thereby indirectly achieving a detachable connection with the housing 10.

[0023] In one embodiment, the protective shell 100 further includes an operating member 28 connected to the slider 20. The operating member 28 is movably engaged with the connector 12 and exposed on the connector 12 for user operation. The user can move the operating member 28 relative to the connector 12 to drive the slider 20 to slide within the first groove 22, thereby enabling the first locking part 16 and the second locking part 18 to form a locking effect or release the locking effect.

[0024] Understandably, the operating element 28 can be rotatably mounted on the connecting element 12, and rotate relative to the connecting element 12 to drive the slider 20 to slide. For example, the rotational output of the operating element 28 can be converted into the linear output of the slider 20 through the cooperation of a gear and rack. Alternatively, the operating element 28 can be slidably mounted on the connecting element 12 and kept relatively fixed relative to the slider 20 in the sliding direction. The operating element 28 drives the slider 20 to slide relative to the connecting element 12.

[0025] Optionally, the connecting member 12 has a second sliding groove 30 on the side away from the housing 10. The second sliding groove 30 is connected to the first sliding groove 22 and extends along the sliding direction of the slider 20. The operating member 28 is slidably installed in the second sliding groove 30 and is relatively fixed to the slider 20 in the sliding direction. The length of the second sliding groove 30 is greater than the length of the operating member 28, so that the operating member 28 can slide within the second sliding groove 30 to drive the slider 20 to slide within the first sliding groove 22. The operating member 28 drives the slider 20 to slide by sliding, so that the operating member 28 and the slider 20 only need to be kept relatively fixed. The connection method is simple and helps to reduce manufacturing and assembly difficulties.

[0026] The surface of the operating component 28 is provided with an anti-slip structure, which can increase the friction between the operating component 28 and the user's fingers, making it easier for the user to slide the operating component 28. Optionally, the anti-slip structure can be an anti-slip raised strip on the surface of the operating component 28, or it can be an anti-slip raised dot or a damping layer on the surface of the operating component 28.

[0027] The operating member 28 includes an operating part 32 and a fixing part 34 connected to one side of the operating part 32. The second slide groove 30 includes a first groove 33 exposed on the surface of the connector 12 and a second groove 35 connecting the first groove 33 and the first slide groove 22. The operating part 32 is movably housed in the first groove 33, and the end of the fixing part 34 away from the operating part 32 passes through the second groove 35 and is fixedly connected to the slider 20. Along the sliding direction of the slider 20, the length of the first groove 33 is greater than the length of the operating part 32, and the length of the second groove 35 is greater than the length of the fixing part 34 and less than the length of the first groove 33, so that the operating member 28 can slide within the second slide groove 30.

[0028] Optionally, the slider 20 is provided with a connecting hole 36, and the fixing part 34 of the operating member 28 is inserted into the connecting hole 36 to form a fixed connection with the slider 20.

[0029] In one embodiment, the locking structure 14 further includes an elastic element 38 located between the slider 20 and the end wall of the first groove 22. Optionally, the first locking part 16 is located at one end of the slider 20, and the first groove 22 has an opening 24 corresponding to the first locking part 16. The opening 24 is opposite to the second locking part 18. The elastic element 38 is located at the end of the slider 20 away from the first locking part 16, and the end wall refers to the inner wall of the first groove 22 away from the opening 24. When the slider 20 moves away from the second locking part 18 under the action of an external force, the distance between the slider 20 and the end wall decreases, and the slider 20 will squeeze the elastic element 38, so that the elastic element 38 forms a spring force that drives the slider 20 to move closer to the second locking part 18. After the external force driving the slider 20 to move disappears, the slider 20 will move closer to the second locking part 18 under the spring force of the elastic element 38, achieving the effect of automatic reset without requiring manual reset by the user.

[0030] Optionally, the elastic element 38 is a spring, with its two ends abutting against the end of the slider 20 away from the first locking part 16 and the end groove wall of the first sliding groove 22, respectively. When the slider 20 moves away from the second locking part 18 under the action of external force, the slider 20 will squeeze the spring and cause the spring to contract. After the external force disappears, the spring will extend under the action of elastic force and push the slider 20 to move closer to the second locking part 18.

[0031] A protrusion 40 is provided at the end of the slider 20 away from the first locking part 16. The protrusion 40 extends along the sliding direction of the slider 20. The elastic element 38 is a spring sleeved on the outside of the protrusion 40. The protrusion 40 can support the spring, thereby limiting the spring in the direction perpendicular to the sliding direction and enhancing the stability of the spring between the slider 20 and the connecting member 12. The end of the protrusion 40 away from the slider 20 is spaced a certain distance from the end wall of the first sliding groove 22 to leave space required for the slider 20 to slide.

[0032] One side of the first slide groove 22 extends through the surface of the connector 12 facing the housing 10, forming a mounting opening 42 on the side of the first slide groove 22 facing the housing 10. The mounting opening 42 and the opening 24 are located on adjacent sides of the first slide groove 22, respectively. The opening 24 is located on the side of the first slide groove 22 in the sliding direction, and the mounting opening 42 is located on the side of the first slide groove 22 perpendicular to the sliding direction. The slider 20 can be installed into the first slide groove 22 from one side of the connector 12 through the mounting opening 42, and then the connector 12 is installed into the housing 10.

[0033] The slider 20 is provided with an extension 44, which extends along the sliding direction of the slider 20 and is located within the mounting opening 42. That is, the extension 44 can partially block the mounting opening 42. The elastic member 38 is located between the extension 44 and the bottom wall of the first groove 22, which is the inner wall of the first groove 22 opposite to the mounting opening 42. In an optional example, the first locking structure 16 is located at one end of the slider 20, and the extension 44 is located at the end of the slider 20 away from the first locking structure 16. The extension 44 can limit the elastic member 38 in a direction perpendicular to the sliding direction, preventing the elastic member 38 from falling between the slider 20 and the connector 12 through the mounting opening 42.

[0034] The end wall of the first groove 22, away from the opening 24, is recessed to form a clearance groove 45. The clearance groove 45 extends away from the opening 24 and is disposed opposite to the extension 44 so that the extension 44 can pass through. When the slider 20 slides away from the second locking part 18, the extension 44 can be inserted into the clearance groove 45 and slide within the clearance groove 45, thus preventing the extension 44 from affecting the sliding of the slider 20.

[0035] Optionally, the first locking part 16, the extension part 44 and the slider 20 are integrally formed, and the first locking part 16 and the extension part 44 are located on opposite sides of the slider 20 and extend in opposite directions, so that the three together form a "convex" shape with a high middle and low sides.

[0036] The slider 20 is provided with a limiting groove 46 extending along its sliding direction. The limiting groove 46 is spaced apart from the surface of the slider 20 away from the mounting opening 42, meaning that the limiting groove 46 does not extend to limit the surface of the slider 20 away from the housing 10. The connecting member 12 is provided with a limiting member 48, which passes through the limiting groove 46, and the limiting member 48 and the slider 20 can move relative to each other in the extending direction of the limiting groove 46, meaning that the limiting member 48 does not affect the sliding of the slider 20. The limiting member 48 can limit the slider 20 in a direction perpendicular to the sliding direction, preventing the slider 20 from falling out of the first sliding groove 22 through the mounting opening 42. For example, in a direction perpendicular to the sliding direction, the limiting groove 46 is located at the middle position of the slider 20, and the limiting groove 46 is spaced a certain distance from both the side near the housing 10 and the side away from the housing 10.

[0037] Optionally, the limiting member 48 is a limiting shaft, the limiting groove 46 passes through the opposite sides of the slider 20, the limiting shaft passes through the limiting groove 46, and both ends extend to the outside of the limiting groove 46 and are connected to the opposite side walls of the first sliding groove 22. For example, there are two limiting members 48, and the two limiting members 48 are arranged at intervals along the sliding direction of the slider 20.

[0038] In one embodiment, there are two locking structures 14, each located at one end of the connector 12. Each locking structure 14 includes a slider 20, with a first locking portion 16 at each of the two opposing ends of the sliders 20. The housing 10 has two corresponding second locking portions 18, which engage with the two first locking portions 16. When the connector 12 is connected to the housing 10 via the locking structures 14, the first locking portions 16 on the two sliders 20 are inserted into a corresponding second locking portion 18, thereby creating a locking effect on both ends of the connector 12 and enhancing the stability of the connection between the connector 12 and the housing 10.

[0039] The number of operating components 28 can be one, which is connected to one of the sliders 20, while the other slider 20 is not connected to the operating component 28, so that one of the locking structures 14 has a manual unlocking effect, while the other locking structure 14 does not have a manual unlocking effect. Alternatively, the number of operating components 28 can also be two, with each operating component 28 connected to one slider 20, so that both locking structures 14 have a manual unlocking effect.

[0040] Optionally, there are two locking structures 14 and one operating member 28. The operating member 28 is connected to the slider 20 of one of the locking structures 14. The first locking part 16 is a latch, and the second locking part 18 is a lock hole. When removing the connector 12 from the housing 10, the operating member 28 can be slid first to drive the slider 20 to slide, causing the latch to retract from the lock hole. Then, the end of the connector 12 with the operating member 28 can be retracted from the receiving groove 26. The connector 12 can then be slid within the receiving groove 26, causing the latch on the slider 20 at the other end of the connector 12 to retract from the lock hole, thus separating the connector 12 entirely from the housing 10. During the installation of connector 12 to housing 10, the other end of connector 12 can be placed in receiving groove 26 first, and the latch at that end can be inserted into the lock hole. Then, the other locking structure 14 can be unlocked by operating member 28. After placing the end of connector 12 with operating member 28 in receiving groove 26, the operating member 28 can be released, and the latch at that end can be automatically inserted into the lock hole under the action of spring. The installation and removal of connector 12 can be realized by setting one operating member 28, which helps to simplify the structure of protective housing 100.

[0041] In one embodiment, the housing 10 includes a back plate 50 and a frame 52 surrounding the outer periphery of the back plate 50. The frame 52 and the back plate 50 enclose a storage space 54 for storing electronic devices. The housing 10 is fitted onto the outside of the electronic devices through the storage space 54. The connector 12 is disposed on the outside of the frame 52, i.e., on the side away from the storage space 54.

[0042] The specific shape of the connector 12 is not limited and can be designed according to the type and specific structure of the external accessories. For example, when the external accessories have a long groove, the connector 12 can also be set to be long, so that the external accessories can be fitted onto the outside of the connector 12 through the groove.

[0043] This utility model also provides an electronic device accessory 1, including a protective shell 100 and a cover plate 200. The cover plate 200 is the external accessory described above. The cover plate 200 is connected to the connector 12 on the frame 52 and can rotate relative to the shell 10 to cover or open the storage space 54. When the electronic device is not in use, the cover plate 200 can be rotated to cover the storage space 54, thereby covering the screen of the electronic device and forming a better protection effect. When the electronic device is in use, the cover plate 200 can be rotated to open the storage space 54, thereby exposing the electronic device, or the connector 12 can be removed from the shell 10 to separate the cover plate 200 from the shell 10, preventing the cover plate 200 from affecting the user's use of the electronic device. Since the electronic device accessory 1 uses the above-described protective shell 100, it has at least all the beneficial effects brought by the protective shell 100 in the above embodiments, which will not be described in detail here.

[0044] The cover plate 200 includes a main body 201 and a bent portion 202 located on one side of the main body 201. The main body 201 can rotate relative to the bent portion 202. For example, a crease can be provided at the connection between the two to allow the main body 201 to rotate relative to the bent portion 202. The main body 201 is used to cover or open the storage space 54, and the bent portion 202 is fixed relative to the connector 12.

[0045] Optionally, the bent portion 202 is elongated and has an elongated groove 203. The part of the connector 12 located outside the frame 52 is adapted to the shape of the groove 203 and is also elongated. The bent portion 202 is fitted onto the outside of the connector 12 through the groove 203.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
