Detailed Implementation

[0042] In view of this, the core of this application is to provide a locking device to improve the data security of terminal devices.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] like Figures 1 to 11 As shown in the figure, this application discloses a locking device for making the cover plate 100 of the chassis and the chassis body 200 in a detachable or non-detachable state, wherein the cover plate 100 and the chassis body 200 enclose a receiving space.

[0045] The locking device includes a first locking mechanism 300 and a second locking mechanism 400. At least a portion of the first locking mechanism 300 is disposed on the side of the cover plate 100 outside the receiving space, and the second locking mechanism 400 is disposed inside the receiving space.

[0046] Specifically, when the first locking mechanism 300 is in the unlocked state, the second locking mechanism 400 can be in the first state, so that the cover plate 100 and the chassis body 200 are in a detachable state; when the first locking mechanism 300 is in the locked state, the second locking mechanism 400 is in the second state, so that the cover plate 100 and the chassis body 200 are in a non-detachable state.

[0047] When using the locking device disclosed in this application, the cover plate 100 and the chassis body 200 enclose a receiving space. At least a portion of the first locking mechanism 300 is disposed on the side of the cover plate 100 outside the receiving space, so that the first locking mechanism 300 can switch between an unlocked state and a locked state. The second locking mechanism 400 is disposed within the receiving space. When the first locking mechanism 300 is in the unlocked state, the second locking mechanism 400 can be in the first state, so that the cover plate 100 and the chassis body 200 are in a detachable state. That is, when it is necessary to remove the cover plate 100, the first locking mechanism 300 must first be in the unlocked state, and then the second locking mechanism 400 must be in the locked state. Only when the second locking mechanism 400 is in the first state can the cover plate 100 and the chassis body 200 be in a detachable state. That is, before removing the cover plate 100, a secondary unlocking is required. When the first locking mechanism 300 is in the locked state, the second locking mechanism 400 is in the second state, so that the cover plate 100 and the chassis body 200 are in a non-detachable state. In other words, when it is necessary to lock the cover plate 100, the second locking mechanism 400 must be in the second state, and the first locking mechanism 300 must be in the locked state. That is, the cover plate 100 and the chassis body 200 are in a non-detachable state through two-stage locking. Therefore, the locking device provided in this application achieves two-stage locking and two-stage unlocking through the first locking mechanism 300 and the second locking mechanism 400, which improves the security of the internal hardware components and stored data of electronic devices.

[0048] It should be understood that the number of the aforementioned cover plate 100 can be one, two, or four, etc. In practical applications, the number of cover plates 100 can be adjusted according to the number of electronic components and the requirements for installation space. As long as the number can meet the usage requirements, it is within the scope of protection of this application.

[0049] Optionally, in a specific embodiment of this application, there are two cover plates 100, namely a first cover plate 101 and a second cover plate 102 disposed on both sides of the chassis body 200. The first cover plate 101 is located on the side of the chassis body 200 where the main chassis is disposed, and the main chassis is used to install electronic components such as the motherboard, CPU, memory modules and graphics card. The second cover plate 102 is located on the side of the chassis body 200 where the auxiliary chassis is disposed, and the auxiliary chassis is used to install electronic components such as the power supply and hard drive. The first cover plate 101 and the second cover plate 102 together with the chassis body 200 form the aforementioned accommodating space.

[0050] In another embodiment, the chassis body 200 forms a first accommodating space with the first cover plate 101 and a second accommodating space with the second cover plate 102. The first accommodating space and the second accommodating space are separated by a motherboard disposed in the chassis body. The same electronic devices can be disposed on both sides of the motherboard, or different electronic devices can be disposed on both sides of the motherboard. That is, processors (CPU, GPU, etc.), memory, power supply modules, etc. can be disposed on both sides of the motherboard respectively.

[0051] Since the hard drive is the main storage medium of electronic devices, in this embodiment, the hard drive is installed in an auxiliary chassis, and the second cover plate 102 is located on the side of the chassis body 200 where the auxiliary chassis is installed. Therefore, in order to improve the data installation capability of electronic devices, it is necessary to improve the security of the auxiliary chassis where the hard drive is installed. In this embodiment, the second cover plate 102 needs to be unlocked by the first locking mechanism 300 and the second locking mechanism 400 to be in a detachable state from the chassis body 200, exposing the hard drive installed in the auxiliary chassis, thereby improving the data security of electronic devices.

[0052] Specifically, the first part of the first locking mechanism 300 is disposed on the first side of the first cover plate 101, which is the side of the first cover plate 101 facing away from the receiving space. The first part enables the first locking mechanism 300 to be in a locked or unlocked state. The second locking mechanism 400 is used to make the second cover plate 102 and the chassis body 200 in a detachable or non-detachable state, so that when the second cover plate 102 needs to be removed, the first part first unlocks the first locking mechanism 300, exposing the second locking mechanism 400 in the receiving space. Mechanism 400, then the second locking mechanism 400 is in the first state, thereby making the second cover plate 102 and the chassis body 200 detachable, thus improving the data security of the hard drive in the auxiliary chassis physically; when it is necessary to make the second cover plate 102 and the chassis body 200 non-detachable, firstly the second locking mechanism 400 located in the accommodating space is in the second state, and then the first locking mechanism 300 is in the locking state, realizing the second-level locking of the second cover plate 102, thereby improving the data security of the hard drive in the auxiliary chassis.

[0053] Furthermore, the first locking mechanism 300 also includes a second part disposed on the second side of the first cover plate 101, the second side being the side of the first cover plate 101 facing the accommodating space, so that the second part and the second locking mechanism 400 are designed as a linkage structure or a non-linkage structure, so that the second cover plate 102 and the chassis body 200 are in a detachable state or a non-detachable state.

[0054] Specifically, when the second locking mechanism 400 and the second part are linked, a linkage transmission mechanism is provided between the first locking mechanism 300 and the second part. As the first locking mechanism 300 changes state, the linkage transmission mechanism enables the second locking mechanism 400 to perform a corresponding state switching action as the first locking mechanism 300 changes state, so that the second cover plate 102 and the chassis body 200 are in a detachable or non-detachable state.

[0055] The aforementioned linkage transmission mechanism can be a linkage mechanism or a crank-slider mechanism, etc. Any structure that can achieve linkage between the second locking mechanism 400 and the second part falls within the scope of protection of this application.

[0056] Alternatively, when the second locking mechanism 400 is not linked with the second part, the second locking mechanism 400 is an independent structure, and the state switching of the first locking mechanism 300 cannot cause the state switching of the second locking mechanism 400. This allows the first locking mechanism 300 to complete its state switching before the second locking mechanism 400 is switched. Through two state switchings, the second cover plate 102 and the chassis body 200 are either in a detachable or non-detachable state.

[0057] It should be noted that the first cover plate 101 can be integrally formed with the chassis body 200, that is, the first cover plate 101 and the chassis body 200 are not detachable, only the second cover plate 102 is detachably connected to the chassis body 200.

[0058] Alternatively, both the first cover plate 101 and the second cover plate 102 can be detachably connected to the chassis body 200. The first locking mechanism 300 also includes a first locking component that is linked to the first part. At least a portion of the first locking component is disposed at the edge of the first cover plate 101. The chassis body 200 is provided with a first assembly structure at least at the edge of the corresponding first cover plate 101, so that when the first locking mechanism 300 is in the locked state, it cooperates with at least a portion of the first locking component to make the first cover plate 101 and the chassis body 200 in a non-detachable state.

[0059] Specifically, the first locking mechanism 300 is a lock, the first locking component includes a linkage clamping member, the first assembly structure is a locking hole, and part of the lock cylinder is located on the first side of the first cover plate 101. By rotating the lock cylinder, the linkage clamping member linked with the lock cylinder can perform telescopic movement. Since part of the linkage clamping member is located at the edge of the first cover plate 101, as the linkage clamping member telescopic, the linkage clamping member can cooperate with the corresponding locking hole, so that the first cover plate 101 is in a non-removable state.

[0060] Furthermore, the locking device also includes a third locking mechanism disposed on the third side of the second cover plate 102, the third side being the side of the second cover plate 102 facing away from the receiving space. The third locking mechanism cooperates with the first locking mechanism 300 to put the second locking mechanism 400 in a first state or a second state, so as to further improve the safety of the locking device through the cooperation of the first locking mechanism 300 and the third locking mechanism.

[0061] Specifically, the second locking mechanism 400 achieves the locking function between the second cover plate 102 and the chassis body 200 through the cooperation of its first and second mating parts. The first mating part can only be located in the first preset locking position when the first locking mechanism 300 is in the locked state, and the second mating part can only be located in the second preset locking position when the third locking mechanism is in the locked state. Therefore, only when the second mating part is located in the second preset locking position by the third locking mechanism and simultaneously when the first mating part is located in the first preset locking position by the first locking mechanism 300, can the first and second mating parts cooperate, and the second locking mechanism 400 can switch to the second state, making the second cover plate 102 and the chassis body 200 non-removable. The first mating component can only be located in the first preset unlock position when the first locking mechanism 300 is in the unlocked state, and the second mating component can only be located in the second preset unlock position when the third locking mechanism is in the unlocked state. Therefore, the second locking mechanism 400 can only be in the first state when the first mating component is located in the first preset unlock position by the first locking mechanism 300 and the second mating component is located in the second preset unlock position by the third locking mechanism. Alternatively, the second locking mechanism 400 is in the first state when either the first mating component or the second mating component is located in the corresponding preset unlock position, making the second cover plate 102 and the chassis body 200 detachable. This further improves the data security of the electronic device.

[0062] like Figure 11 As shown, in another specific embodiment of this application, when the number of electronic components is small and only one detachable cover plate is provided to meet the space for the installation and removal of electronic components, the number of cover plates is only one, and only this cover plate is detachably connected to the chassis body 200 so that after removing the cover plate, the electronic components can be installed and removed by removing the cover plate.

[0063] Specifically, the cover plate 100 is designated as the third cover plate 103. The third cover plate 103 is disposed on the first side of the chassis body 200. The third cover plate 103 and the chassis body 200 enclose a receiving space. The first locking mechanism 300 and the second locking mechanism 400 are both disposed on the third cover plate 103. Through the cooperation of the first locking mechanism 300 and the second locking mechanism 400, the third cover plate 103 and the chassis body 200 are either in a detachable state or a non-detachable state.

[0064] The first locking mechanism 300 and the second locking mechanism 400 are linked and disposed on both sides of the third cover plate 103, so that the third cover plate 103 and the chassis body 200 are in a detachable or non-detachable state through the first locking mechanism and the second locking mechanism 400.

[0065] When the first locking mechanism 300 is in the locked state, the third cover plate 103 is in a non-removable state from the chassis body 200 via the second locking mechanism 400 or via the first locking mechanism 300 and the second locking mechanism 400; when the first locking mechanism 300 is in the unlocked state, the second locking mechanism 400 makes the third cover plate 103 detachable from the chassis body 200.

[0066] It should be understood that the second locking mechanism 400 provided in this application can be the same as the first locking mechanism 300, using a directly purchased or specially designed lock, that is, the first locking mechanism 300 and the second locking mechanism 400 can be opened by two different keys respectively; or the second locking mechanism 400 can be set up separately, so that the key of the locking device is only one key that can open the first locking mechanism 300, reducing the number of keys and locks. Compared with the locking mechanism using two sets of locks and two sets of keys, the structural complexity is reduced, the cost is reduced, and the security of the locking device is further improved.

[0067] Optionally, embodiments of this application provide a specific locking device, such as... Figures 2 to 6 As shown, the second locking mechanism 400 includes a drive mechanism 401 and a movable member 402 that are movably connected. The cover plate 100 is provided with a receiving groove corresponding to the movable member 402. The drive mechanism 401 can provide a driving force to the movable member 402 to drive the movable member 402 to enter or exit the receiving groove near the first end of the receiving groove, so that the cover plate 100 and the chassis body 200 are in a detachable state or a non-detachable state.

[0068] Specifically, when the first end enters the receiving groove, the cover plate 100 and the chassis body 200 are in a non-removable state; when the first end exits the receiving groove, the cover plate 100 and the chassis body 200 are in a detachable state.

[0069] The aforementioned drive mechanism 401 is movably disposed on the chassis body 200. The drive mechanism 401 has at least one unlocking path that allows the movable part 402 to enter or exit the receiving slot near the first end of the receiving slot, so that the cover plate 100 and the chassis body 200 are in a detachable or non-detachable state.

[0070] It should be noted that the above-mentioned unlocking path can be a straight path or a curved path. This application does not specifically limit the above-mentioned unlocking path. As long as the path can enable the movable part 402 to enter or exit the receiving groove near the first end of the receiving groove, it is within the protection scope of this application.

[0071] In one specific embodiment of this application, the unlocking path is a straight path. The drive mechanism 401 is provided with a slide groove 4012, and the bottom of the chassis body 200 is provided with two sliding connecting posts 202, which respectively pass through both ends of the slide groove 4012, so that the drive mechanism 401 is slidably disposed on the chassis body 200, allowing the drive mechanism 401 to slide along the length direction of the chassis body 200. Furthermore, the drive mechanism 401 is provided with a connecting post 4011, and the movable member 402 is provided with a guide groove 4021 for slidingly engaging with the connecting post 4011. The drive mechanism 401 can slide along the first direction. The guide groove 4021 is inclined to the first direction so that when the operator moves the drive mechanism 401, the drive mechanism 401 slides along the first direction. As the drive mechanism 401 slides, the connecting column 4011 applies a force to the guide groove 4021, so that the drive mechanism 401 drives the movable part 402 to move along the second direction through the guide groove 4021 and the connecting column 4011, so that the movable part 402 moves closer to or away from the receiving groove, so that the first end of the movable part 402 that is close to the receiving groove can enter or exit the receiving groove.

[0072] The first and second directions mentioned above can be set perpendicular to each other or inclined. As long as the setting method enables the drive mechanism 401 to drive the movable part 402 to move closer to or away from the receiving groove through the guide groove 4021, it is within the protection scope of this application. Optionally, the first and second directions provided in the embodiments of this application are set perpendicularly, the first direction is the length direction of the chassis body 200, and the second direction is the width direction of the chassis body 200.

[0073] Furthermore, the degree of inclination of the guide groove 4021 relative to the first direction is not specifically limited. In practical applications, the degree of inclination of the guide groove 4021 can be adaptively adjusted according to parameters such as the sliding stroke of the drive mechanism 401 and the sliding stroke of the moving part 402.

[0074] In addition, in the above specific embodiment, the drive mechanism 401 is also provided with a mounting post, the second locking mechanism 400 also includes a torsion spring, the chassis body 200 is provided with a mounting hole, and the two ends of the torsion spring are respectively connected to the mounting post and the mounting hole to connect the drive mechanism 401 and the chassis body 200, apply a damping force to the drive mechanism 401, so that the drive mechanism 401 is fixed at the first limit position that allows the movable part 402 to enter the receiving groove or at the second limit position that allows the movable part 402 to exit the receiving groove, and improve the tactile feel of the drive mechanism 401 between the first limit position and the second limit position.

[0075] In another specific embodiment of this application, the unlocking path is still a straight path. The drive mechanism 401 and the movable part 402 are fixedly connected so that the sliding directions of the drive mechanism 401 and the movable part 402 are the same. That is, by directly pushing the drive mechanism 401, the drive mechanism 401 directly pushes the movable part 402, so that the first end of the movable part 402 near the receiving groove can enter or exit the receiving groove.

[0076] In another specific embodiment of this application, the unlocking path is a curved path. The drive mechanism 401 includes a drive part movably disposed on the chassis body 200 and a hinge part for hinged with the movable member 402, so that when the drive part makes a first type of movement relative to the chassis body 200, the first end of the movable member 402 is driven into or out of the receiving groove through the hinge part. The first type of movement is different from the sliding of the drive mechanism 401 toward or away from the receiving groove.

[0077] The aforementioned first type of motion can be rotation or oscillation, etc. Correspondingly, the drive unit can make the movable part 402, which is hinged to its hinge part, perform reciprocating linear motion through a cam rotation mechanism, crank rocker mechanism, or incomplete gear and closed rack and pinion structure. Any structure that can make the movable part 402 approach the first end of the receiving groove and enter or exit the receiving groove through a curved path is within the scope of protection of this application.

[0078] Furthermore, the locking device provided in this application also includes an electronically controlled drive component. The first locking mechanism 300 and the second locking mechanism 400 are both electrically connected to the electronically controlled drive component, so that the electronically controlled drive component can receive the state switching signal of the first locking mechanism 300 and generate a linkage trigger signal after receiving the state switching signal of the first locking mechanism 300. After the second locking mechanism 400 receives the linkage trigger signal, the drive mechanism 401 of the second locking mechanism 400 moves to provide driving force to the movable member 402, so that the movable member 402 enters or exits the receiving groove near the first end of the receiving groove.

[0079] In addition, such as Figure 5 and Figure 6As shown, in order to improve the accuracy of the movement trajectory of the movable part 402, the chassis body 200 is also provided with a guide mechanism 201. The guide mechanism 201 includes multiple sets of L-shaped bends arranged opposite each other to limit the offset of the movable part 402 during the movement process, so that the end of the movable part 402 can accurately enter the receiving groove, and prevent the trajectory of the movable part 402 from deviating during the movement process, which would cause the end of the movable part 402 to get stuck on the edge of the receiving groove and be unable to enter the receiving groove.

[0080] The second locking mechanism 400 provided in this application also includes a stop structure 404 disposed on the cover plate 100. The stop structure 404 is movably connected to the movable member 402 so that the state switching of the movable member 402 can cause the state switching of the stop structure 404, so that the stop structure 404 and the movable member 402 are linked.

[0081] Specifically, when the first end of the movable part 402 enters the receiving groove, the stop structure 404 has a first configuration to provide resistance to the sliding of the cover plate 100 relative to the chassis body 200; when the first end exits the receiving groove, the stop structure 404 has a second configuration to allow the cover plate 100 to slide relative to the chassis body 200.

[0082] like Figures 7 to 10 The stop structure 404 includes an anti-reverse body disposed on the cover plate 100 and a spring arm 4041 disposed on the anti-reverse body. The spring arm 4041 is provided with a stop latching structure 4042, and the chassis body 200 is provided with an anti-reverse latching hole that can cooperate with the stop latching structure 4042.

[0083] As the first end of the aforementioned movable component 402 enters the receiving groove, the stop latching structure 4042 on the spring arm 4041 engages with the anti-retraction latching hole. At this time, the stop structure 404 is in its first state. The cooperation between the stop latching structure 4042 and the anti-retraction latching hole provides resistance to the sliding of the cover plate 100 relative to the chassis body 200, preventing the cover plate 100 from sliding relative to the chassis body 200 and improving the connection reliability between the cover plate 100 and the chassis body 200. As the second end of the aforementioned movable component 402 exits the receiving groove, the stop latching structure 4042 on the spring arm 4041 disengages from the anti-retraction latching hole. At this time, the stop structure 404 is in its second state. The resistance to the sliding of the cover plate 100 relative to the chassis body 200 is eliminated, allowing the cover plate 100 to slide relative to the chassis body 200. Thus, through the linkage design of the movable component 402 and the stop structure 404, the anti-retraction function of the cover plate 100 and the chassis body 200 is realized.

[0084] The aforementioned movable component 402 and the stop structure 404 can be linked by a linkage structure or a crank-slider mechanism, etc. Any mechanism that can cause the stop structure 404 to switch states through the state switching of the movable component 402 is within the scope of protection of this application.

[0085] It should be understood that the aforementioned stop structure 404 can also be designed so that the movable part 402 and the stop structure 404 are not linked, and a pressing part 4043 is provided on the spring arm 4041. By manually pressing the pressing part 4043, the stop locking structure 4042 on the spring arm 4041 can be inserted into or pushed out of the anti-retraction locking hole on the chassis body 200.

[0086] In addition, such as Figure 7 As shown, the second locking mechanism 400 also includes a rotating connection structure and a clamping structure disposed on the second cover plate 102. The chassis body 200 is provided with a rotating slot that can cooperate with the rotating connection structure and a locking hole that can cooperate with the clamping structure, so that the second cover plate 102 and the chassis body 200 are initially positioned by the cooperation of the rotating connection structure and the rotating slot. After the initial positioning of the second cover plate 102 and the chassis body 200 is completed, the second cover plate 102 is rotated so that the clamping structure on the second cover plate 102 is engaged with the locking hole on the chassis body 200, thereby realizing the engagement of the second cover plate 102 and the chassis body 200.

[0087] The aforementioned rotating connection structure is a hook with a circular arc cross-section, which hooks into the rotating slot of the chassis body 200 to achieve the initial positioning of the second cover plate 102 and the chassis body 200. After the second cover plate 102 and the chassis body 200 have completed the initial positioning, the second cover plate 102 is rotated until the stop structure 404 is not engaged in the anti-retraction hole. Then, the second cover plate 102 is slid forward on the chassis body 200, and is engaged with the corresponding holes and slots on the chassis body 200 by the locking structure around the second cover plate 102, so as to control the gap between the second cover plate 102 and the chassis body 200, improve the parallelism and symmetry of the gap between the second cover plate 102 and the chassis body 200, thereby improving the appearance quality of the electronic device.

[0088] In addition, this application also discloses an electronic device, including a chassis body 200, a cover plate 100 and a locking device as described in any of the above, thus possessing all the technical effects of the above-mentioned locking devices, which will not be described in detail here.
