[0019] Please refer to Figure 1, which is a schematic diagram of the structure of the terminal device 200 provided in this embodiment of the application. The terminal device 200 includes a locking device 100 and a component 210. The locking device 100 is used to detachably hold the component 210, which has a card slot 220. The locking device 100 has locking, unlocking, and reset functions. The terminal device 200 may be a server, and the component 210 may be a board, such as an OCP (Open Compute Project) card.

[0020] In this embodiment, the terminal device 200 includes a set of locking devices 100, which are disposed on one side of the component 210. In other embodiments, the terminal device 200 may also include two sets of locking devices 100, which are respectively disposed on both sides of the component 210.

[0021] Please refer to Figures 2, 3 and 4 together. The locking device 100 may include a base 10, a fixing member 20, a driving member 40, a movable member 30 and an elastic member 50. The fixing member 20 is fixedly connected to the base 10, the driving member 40 is rotatably connected to the base 10, the movable member 30 is movably connected to the base 10, and the elastic member 50 is elastically connected to the movable member 30. The elastic member 50 is used to perform a reset function.

[0022] The base 10 may include a support portion 11 and a baffle portion 12, both of which extend along a first direction L1. Both sides of the support portion 11 protrude from the baffle portion 12. A groove 16 is formed on one side of the support portion 11 and the baffle portion 12. The groove 16 is used to guide the element 210 to slide along the first direction L1.

[0023] The baffle portion 12 may include a through groove 121 and an inclined surface 122. The through groove 121 extends through the baffle portion 12 along the second direction L2 and communicates with the sliding groove 16. The baffle portion 12 and the support portion 11 are arranged along a third direction L3. The first direction L1, the second direction L2, and the third direction L3 all intersect and are not coplanar. In this embodiment, the first direction L1, the second direction L2, and the third direction L3 are all perpendicular to each other.

[0024] The inclined surface 122 is a surface that forms the through groove 121. The inclined surface 122 intersects the first direction L1, the second direction L2, and the third direction L3. The inclined surface 122 is used to block the movable part 30 so that the movable part 30 rotates around the first direction L1 and then exits from the slot 220. The inclined surface 122 has a certain curvature, that is, the inclined surface 122 is not planar. The curvature of the inclined surface 122 is adapted to the movement trajectory of the movable part 30 relative to the inclined surface 122, which is beneficial to the convenience of driving the movable part 30 to rotate.

[0025] The base 10 may also include a first fixing part 13 and a second fixing part 14. The first fixing part 13 is fixed to the baffle part 12, and the second fixing part 14 is fixed to the baffle part 12. The first fixing part 13 and the second fixing part 14 are arranged at intervals along the first direction L1.

[0026] The locking device 100 may further include a fixed shaft 60, which passes through the first fixed part 13 and the second fixed part 14 and extends along the second direction L2. The driving member 40 is sleeved on the fixed shaft 60 and is used to rotate about the fixed shaft 60 around the second direction L2.

[0027] The fixing member 20 is located on the side of the baffle portion 12 opposite to the slide groove 16, and the fixing member 20 is spaced apart from the first fixing portion 13 and the second fixing portion 14. The fixing member 20 can be fixed to the base 10 by means of the pin 21. The base 10 also includes a protrusion 15, which is fixed to the baffle portion 12 and passes through the fixing member 20. The protrusion 15 facilitates the installation of the fixing member 20.

[0028] A receiving groove 22 is formed between the fixing member 20 and the support part 11. The receiving groove 22 is recessed along the first direction L1, and the opening direction of the receiving groove 22 faces the first fixing part 13 and the second fixing part 14.

[0029] The driving component 40 may include a rotating part 41 and a handle 42. The rotating part 41 is fixed to one end of the handle 42. The end of the handle 42 with the rotating part 41 is sleeved on the fixed shaft 60. The rotating part 41 is located between the first fixed part 13 and the second fixed part 14. When an external force is applied to the handle 42, the handle 42 rotates and drives the rotating part 41 to rotate synchronously around the fixed shaft 60.

[0030] The movable member 30 is capable of moving and rotating about a first direction L1. The movable member 30 may include a first rod portion 31, a second rod portion 32, a connecting portion 33, and a blocking portion 34. The first rod portion 31 and the second rod portion 32 are arranged along the first direction L1, both extending along the first direction L1, and both located on the side of the baffle portion 12 opposite to the slide groove 16. The diameter of the first rod portion 31 is larger than the diameter of the second rod portion 32.

[0031] The connecting part 33 connects the first rod part 31 and the blocking part 34. The rotating part 41 abuts against the end of the first rod part 31 opposite to the second rod part 32. After the rotating part 41 rotates around the fixed axis 60, the rotating part 41 drives the first rod part 31 to move along the first direction L1. The second rod part 32, the connecting part 33, and the blocking part 34 move synchronously with the first rod part 31 along the first direction L1. After the movable part 30 moves along the first direction L1, part of the second rod part 32 extends into the receiving groove 22.

[0032] The connecting part 33 is located in the through groove 121, and the blocking part 34 is located on the side of the slide groove 16 and protrudes into the slide groove 16 relative to the connecting part 33. When the locking device 100 locks the element 210, the blocking part 34 is engaged in the slot 220; when the connecting part 33 moves along the first direction L1 with the first rod part 31, the connecting part 33 abuts against the inclined surface 122, and under the action of the inclined surface 122, the connecting part 33 is driven to rotate around the first direction L1, and the blocking part 34 rotates synchronously with the connecting part 33 around the first direction L1 with the first rod part 31 as the axis of rotation, and the blocking part 34 moves along the third direction L3 toward the direction away from the support part 11, thereby exiting from the slot 220.

[0033] The elastic member 50 includes a main body 51, a first end 52, and a second end 53, with the first end 52 and the second end 53 located at opposite ends of the main body 51. The main body 51 is sleeved on the second rod 32, with both ends of the main body 51 abutting against the fixing member 20 and the first rod 31, respectively. The fixing member 20 has a first groove 23, with the first end 52 located in the first groove 23, and the first end 52 is fixed to the fixing member 20. The first rod 31 has a second groove 311, with the second end 53 located in the second groove 311, and the second end 53 is fixed to the first rod 31.

[0034] When the movable part 30 moves along the first direction L1 toward the side where the fixed part 20 is located, the first rod 31 squeezes the elastic element 50, and the elastic element 50 undergoes compression deformation; when the movable part 30 rotates around the first direction L1, the first rod 31 drives the second end 53 to rotate relative to the first end 52, and the elastic element 50 undergoes torsional deformation.

[0035] Please refer to Figures 5 to 10. The following describes the relationship between the locking device 100 and its various components 210 through a specific unlocking process.

[0036] Please refer to Figures 5 and 6. When the component 210 is placed in the locking device 100, the blocking part 34 is engaged in the slot 220 of the component 210.

[0037] Please refer to Figures 7 and 8. When it is necessary to unlock component 210, an external force is applied to the drive member 40 to rotate handle 42 around the second direction L2. The rotating part 41 rotates synchronously with handle 42. After the rotating part 41 rotates, the drive member 30 moves towards the fixed member 20 along the first direction L1. The drive member 30 drives component 210 to move along the first direction L1 in the slide groove 16 and compresses the elastic member 50, causing the elastic member 50 to undergo compression deformation.

[0038] Please refer to Figures 9 and 10. When the movable part 30 moves along the first direction L1 until the connecting part 33 contacts the inclined surface 122, the inclined surface 122 blocks the connecting part 33 and guides the connecting part 33 to slide along the inclined surface 122. The connecting part 33 rotates about the first direction L1 with the first rod part 31 as the axis of rotation. The blocking part 34 and the first rod part 31 rotate synchronously with the connecting part 33 until the blocking part 34 exits from the slot 220. The rotation of the movable part 30 drives the elastic part 50 to produce torsional deformation. At this time, the locking device 100 engages the locking of the element 210, and the element 210 can pop out from the slide groove 16. The size of the popped-out element 210 is approximately D (see Figure 6).

[0039] After component 210 pops out of slide 16, the force applied to handle 42 is removed, and moving part 30 and driving part 40 return to their initial positions under the action of elastic part 50 (see Figure 6).

[0040] When it is necessary to install the component 210 into the locking device 100, an external force is applied to the drive member 40 to rotate the handle 42 around the second direction L2. After the drive member 40 rotates, it drives the movable member 30 to move along the first direction L1 until the movable member 30 rotates around the first direction L1 and slides the component 210 along the slide groove 16 until the position of the slot 220 corresponds to the position of the through groove 121. The force applied to the handle 42 is removed, and the movable member 30 and the drive member 40 return to their initial positions under the action of the elastic member 50. The blocking part 34 is held in the slot 220.

[0041] The locking device 100 provided in this embodiment allows the element 210 to pop out of the locking device 100 when it is necessary to unlock the element 210. The element 210 can then be pulled out. The process of disassembling the element 210 is simple, and the locking device 100 can also automatically reset under the action of the elastic member 50. The locking device 100 also occupies a small volume.

[0042] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
