Description

Technical Field

[0001] This invention relates to the field of lock technology, and more specifically, to unlocking mechanisms and electronic devices. Background Technology

[0002] Hard drives and other electronic components are typically installed inside a computer case and secured to a rack within the case using locks for theft prevention. However, the current trend in electronic device development is towards miniaturization and simplification, and ordinary locks require significant space, making them unsuitable for the theft prevention needs of small electronic devices' hard drives. Summary of the Invention

[0003] This invention provides an unlocking mechanism and electronic device to solve the technical problem of being unable to lock and unlock target components in narrow spaces.

[0004] The embodiments of the present invention are implemented as follows:

[0005] In a first aspect, the present invention provides an unlocking mechanism for locking or unlocking multiple target components mounted on a base component, comprising multiple swing arms and a connecting rod. The multiple swing arms are sequentially spaced along a first direction and correspond one-to-one with the multiple target components; each swing arm extends along a second direction perpendicular to the first direction; each swing arm is rotatably connected to the base component, and its axis of rotation is parallel to the second direction; each swing arm is provided with a locking portion and a transmission arm. The connecting rod is slidably engaged with the base component along the first direction; the connecting rod is provided with mating grooves sequentially spaced along the first direction, the mating grooves extending along a third direction perpendicular to both the first and second directions; the transmission arm is movably engaged with the mating grooves, and, when the connecting rod slides along the first direction, the engagement of the mating grooves and the transmission arm can cause each swing arm to rotate relative to the base component to a locked state where the locking portion locks the target component or an unlocked state where the locking portion moves away from the unlocked target component.

[0006] When the connecting rod slides along the first direction, the mating groove moves along the first direction. The transmission arm also moves along the first direction under the restriction of the mating groove. The rotating connection between the swing arm and the base is fixed relative to the connecting rod, so that the swing arm rotates under the action of the transmission arm. This allows the locking part on the swing arm to rotate relative to the base to a locked or unlocked state. When the locking part enters the locked state, it can lock the target part on the base. When the locking part enters the unlocked state, it can unlock the target part from the base, so that the operator can safely and securely lock multiple target parts on the base or remove multiple target parts from the base.

[0007] The multiple target components of this invention are divided into multiple groups of target component sets distributed along a first direction, and each group of target component sets includes multiple target components distributed along a second direction. Therefore, a connecting rod can be disposed on one side of the multiple target component sets, and a swing arm can be extended along the second direction between adjacent groups of target components. This allows for the arrangement of multiple swing arms according to the specific distribution of the multiple target components on the base component. By placing the swing arms between adjacent groups of target components, the space occupied by the unlocking mechanism is greatly reduced, and it does not interfere with the original installation arrangement of the multiple target components on the base component, significantly improving the applicability of the unlocking mechanism. Simultaneously, when the connecting rod slides along the first direction, the cooperation of multiple mating grooves and multiple transmission arms can simultaneously drive multiple swing arms to rotate. Since the multiple swing arms also extend along the second direction, the swing arms can simultaneously lock or unlock the multiple target components distributed along the second direction in each target group to the base component. Therefore, the unlocking mechanism of this embodiment has high unlocking efficiency and ease of unlocking.

[0008] In one possible implementation: the unlocking mechanism further includes a locking structure disposed on the base member, the locking structure cooperating with the connecting rod and capable of locking or unlocking the sliding of the connecting rod.

[0009] In one possible implementation: the locking structure includes a locking tongue, and the connecting rod is provided with a linkage part. When the locking tongue rotates, the locking tongue can push the linkage part to make the connecting rod slide along a first direction, and lock the sliding of the connecting rod after driving the rocker arm to rotate to the locked state.

[0010] In one possible implementation: the locking structure further includes an elastic element that is elastically connected between the base member and the connecting rod, and applies an elastic force along a first direction to the connecting rod so that when the locking structure locks the sliding of the connecting rod, the connecting rod elastically holds each of the rocker arms in the locked state of the locking target member.

[0011] In one possible implementation: the target component is disposed on the base component by a locking structure, the locking structure and the base component defining an unlocking space; when the swing arm rotates to the locked state, the locking part enters the unlocking space to fix the locking structure relative to the base component and lock the target component to the base component; when the swing arm rotates to the unlocked state, the locking part disengages from the unlocking space to allow the locking structure to move relative to the base component and unlock the target component from the base component.

[0012] In one possible implementation: each of the swing arms is provided with a plurality of locking parts, the plurality of locking parts of each swing arm are distributed sequentially along the second direction, and the plurality of locking parts can sequentially cooperate with a plurality of target parts distributed sequentially along the second direction.

[0013] In one possible implementation: the base component includes two spaced-apart plates, the connecting rod is located on the side of one plate away from the other plate, the swing arm is located between the two plates, and the two ends of the swing arm are rotatably connected to the two plates respectively.

[0014] In one possible implementation: the swing arm is further provided with a limiting protrusion, the limiting protrusion is provided on the transmission arm and located on the side of the connecting rod close to the plate, the size of the limiting protrusion in the first direction is larger than the size of the mating groove in the first direction, so as to restrict the swing arm from falling off between the two plates.

[0015] In one possible implementation: the mating groove extends downward from the top surface of the connecting rod along a third direction, the transmission arm includes a transmission part that extends along a second direction and extends into the mating groove, and when the connecting rod moves along a first direction, the mating groove applies a force along the first direction to the transmission arm to drive the swing arm to rotate relative to the base component.

[0016] Secondly, the present invention also provides an electronic device, including a base component, a plurality of target components, and the aforementioned unlocking mechanism. The plurality of target components are mounted on the base component. The unlocking mechanism is disposed on the base component and is used to lock or unlock the plurality of target components.

[0067] Some embodiments of the present invention are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0068] Example

[0069] See Figures 1 to 10 This embodiment provides an unlocking mechanism 100 for locking or unlocking multiple target components 300 installed on a base component 200, including multiple swing arms 10 and connecting rods 20. The multiple swing arms 10 are distributed sequentially at intervals along a first direction L and correspond one-to-one with the multiple target components 300; each swing arm 10 extends along a second direction M, which is perpendicular to the first direction L; the swing arms 10 are rotatably connected to the base component 200, and their rotation axis is parallel to the second direction M; the swing arms 10 are provided with a locking part 11 and a transmission arm 12. The connecting rod 20 is slidably fitted to the base member 200 along the first direction L; the connecting rod 20 is provided with mating grooves 21 arranged sequentially at intervals along the first direction L, the mating grooves 21 extending along the third direction N, the third direction N being perpendicular to the first direction L and the second direction M; the transmission arm 12 is movably fitted to the mating grooves 21, and when the connecting rod 20 slides along the first direction L, it can drive each swing rod 10 to rotate relative to the base member 200 to a locked state where the locking part 11 locks the target member 300 or an unlocked state where the locking part 11 moves away from the unlocking target member 300 through the cooperation of the mating grooves 21 and the transmission arm 12.

[0070] Since the mating groove 21 extends along the third direction N and the transmission arm 12 is movably fitted into the mating groove 21, and the rocker arm 10 is rotatably connected to the base component 200, under the constraints of the above structure, when the connecting rod 20 slides along the first direction L, the mating groove 21 moves along the first direction L, and the transmission arm 12 also moves along the first direction L under the constraint of the mating groove 21. The rotatable connection between the rocker arm 10 and the base component 200 is fixed relative to the connecting rod 20, thus allowing the rocker arm 10 to move in the direction of the transmission arm 12. By rotating downwards, the locking part 11 on the lever 10 can be rotated relative to the base member 200 to a locked state or an unlocked state. When the locking part 11 is in the locked state, it can lock the target member 300 onto the base member 200. When the locking part 11 is in the unlocked state, it can unlock the target member 300 from the base member 200, so that the operator can safely and securely lock multiple target members 300 onto the base member 200, or remove multiple target members 300 from the base member 200.

[0071] In this embodiment, the multiple target components 300 are divided into multiple groups of target components 300 distributed along the first direction L. Each group of target components 300 includes multiple target components 300 distributed along the second direction M. Therefore, the connecting rod 20 can be disposed on one side of the multiple groups of target components 300, and the swing rod 10 can be extended along the second direction M between adjacent groups of target components. This allows for the arrangement of multiple swing rods 10 according to the specific distribution of the multiple target components 300 on the base component 200. By placing the swing rods 10 between adjacent groups of target components, the space occupied by the unlocking mechanism 100 is greatly reduced, and the original installation arrangement of the multiple target components 300 on the base component 200 is not interfered with, significantly improving the applicability of the unlocking mechanism 100. Meanwhile, when the connecting rod 20 slides along the first direction L, through the cooperation of multiple mating grooves 21 and multiple transmission arms 12, multiple swing rods 10 can be driven to rotate simultaneously. At the same time, the multiple swing rods 10 extend along the second direction M, so that the swing rods 10 can simultaneously lock multiple target parts 300 distributed along the second direction M in each target group to the base part 200 or simultaneously unlock them from the base part 200. Therefore, the unlocking mechanism 100 of this embodiment has high unlocking efficiency and unlocking convenience.

[0072] In this embodiment, see Figures 7 to 9 The unlocking mechanism 100 also includes a locking structure 30, which is located on the base member 200. The locking structure 30 cooperates with the connecting rod 20 and can lock or unlock the sliding of the connecting rod 20.

[0073] The locking structure 30 can lock the sliding of the connecting rod 20 when the connecting rod 20 drives the swing rod 10 to rotate to the locked state, thereby locking the rotation of the swing rod 10. This allows the swing rod 10 to keep the target part 300 locked to the base part 200, thus preventing the swing rod 10 from accidentally rotating under external interference and causing unlocking problems, and further ensuring the locking reliability of the target part 300 on the base part 200.

[0074] In this embodiment, see Figure 9 The locking structure 30 includes a locking tongue 31 and a linkage part 22 on the connecting rod 20. When the locking tongue 31 rotates, the locking tongue 31 can push the linkage part 22 to make the connecting rod 20 slide along the first direction L, and lock the sliding of the connecting rod 20 after driving the swing rod 10 to rotate to the locked state.

[0075] When the operator rotates the locking tongue 31, the locking tongue 31 can push the linkage 22 to move so that the connecting rod 20 slides along the first direction L, thereby realizing the locking of the target part 300 on the base part 200 at the same time as operating the locking structure 30. This better conforms to the operator's operating habits, and the locking of the connecting rod 20 and the locking of the target part 300 on the base part 200 are completed simultaneously, improving the locking efficiency of the target part 300 on the base part 200.

[0076] Specifically, see Figure 9 The locking structure 30 also includes a rotating part 32, and a locking tongue 31 is eccentrically connected to the rotating part 32. When the operator rotates the rotating part 32, it drives the locking tongue 31 to rotate, so that the locking tongue 31 can push the linkage part 22 to move a long distance during the rotation. After the rotation is completed, the locking tongue 31 can remain in contact with the linkage part 22, so that the connecting rod 20 remains in a fixed position, thereby keeping the swing arm 10 in the locked state. When unlocking is required, the operator rotates the rotating part 32 to drive the locking tongue 31 to rotate. At this time, the locking tongue 31 can either drive the connecting rod 20 to slide along the first direction L by connecting with the linkage part 22, or it can automatically reset the linkage part 22 through other structures to drive the connecting rod 20 to slide along the first direction L, thereby unlocking the connecting rod 20 and unlocking the target part 300 on the base part 200.

[0077] Specifically, see Figure 9 The connecting rod 20 has a clearance opening 23. When the rocker arm 10 is in the unlocked state, the bolt 31 rotates to the clearance opening 23 to prevent interference between the bolt 31 and the connecting rod 20.

[0078] In this embodiment, see Figure 6 and Figure 7 The locking structure 30 also includes an elastic element 33, which is elastically connected between the base member 200 and the connecting rod 20 and applies an elastic force along the first direction L to the connecting rod 20 so that when the locking structure 30 locks the sliding of the connecting rod 20, the connecting rod 20 elastically holds each swing arm 10 in the locked state of the locking target member 300.

[0079] When the rocker arm 10 is in the locked state, the connecting rod 20 is subjected to the elastic force of the elastic member 33 in the first direction L. At this time, the connecting rod 20 holds the multiple rocker arms 10 in the locked state of the locking target member 300 under the action of the elastic member 33. When the locking structure 30 unlocks the sliding of the connecting rod 20, the connecting rod 20 will slide relative to the base member 200 under the action of the elastic member 33, thereby driving the rocker arm 10 to rotate from the locked state to the unlocked state, thereby realizing the unlocking of multiple target members 300 on the base member 200. This realizes the automatic unlocking of multiple target members 300 on the base member 200, without the need for additional operation of the connecting rod 20 after unlocking it through the locking structure 30, which significantly improves the ease of use.

[0080] Specifically, the elastic element 33 in this embodiment is a tension spring, but it can also be a compression spring. In addition, the elastic force in this embodiment can be either tension or compression. The specific structure of the elastic element 33 and the specific type of elastic force applied by the elastic element 33 can be determined according to the actual assembly requirements, without the need for specific limitation.

[0081] In this embodiment, see Figures 2 to 5 The target component 300 is mounted on the base component 200 via the locking structure 400. The locking structure 400 and the base component 200 define an unlocking space 500. When the lever 10 rotates to the locked state, the locking part 11 enters the unlocking space 500 to fix the locking structure 400 relative to the base component 200 and lock the target component 300 to the base component 200. When the lever 10 rotates to the unlocked state, the locking part 11 disengages from the unlocking space 500 so that the locking structure 400 can move relative to the base component 200 and unlock the target component 300 from the base component 200.

[0082] With the above structural design, the target component 300 can be locked to the base component 200 by the locking part 11 when the swing arm 10 rotates to the locked state, and the target component 300 can be unlocked from the base component 200 when the swing arm 10 rotates to the unlocked state. Simultaneously, in this embodiment, since the target component 300 is located on the base component 200 via the latching structure 400, the sliding of the connecting rod 20 can smoothly drive the swing arm 10 to rotate and disengage from the unlocking space 500, without being restricted by any one of the target component 300, the base component 200, or the latching structure 400. This ensures that the locking part 11 can stably unlock the target component 300 on the base component 200 multiple times. Of course, in other embodiments of the present invention, the locking part 11 can also be a snap-fit ​​structure to directly lock the target component 300 to the base component 200. Only the relationship between the first direction L and the slot on the target component 300 needs to be adjusted to achieve smooth engagement and disengagement of the locking part 11 with the slot on the target component 300.

[0083] Specifically, the base component 200 also includes a mounting plate with a first end and a second end. One end of the target component 300 is rotatably connected to the first end, and a locking structure 400 is located at the second end of the mounting plate. A spring is provided between the locking structure 400 and the mounting plate. The locking structure 400 engages with the other end of the target component 300 and can lock the target component 300 onto the mounting plate. Thus, when the lever 10 rotates to the unlocked state, the operator can press the locking structure 400 to disengage the locking structure 400 from the target component 300 and unlock the target component 300 from the mounting plate. When the lever 10 rotates to the locked state, the operator cannot press the locking structure 400 because the locking structure 400 remains engaged with the target component 300, thus preventing the target component 300 from unlocking from the mounting plate and ensuring locking reliability.

[0084] The above description is only for the structure and cooperation relationship of the locking structure 400, the base component 200, the target component 300 and the swing rod 10 in a specific embodiment. In other embodiments of the present invention, the above features can also achieve locking and unlocking in other ways. For example, the locking structure 400 can also be set to unlock from the target component 300 when stretched. At this time, the unlocking space 500 is located above the locking structure 400, and the locking part 11 can enter the upper part of the locking structure 400 when unlocked. The two ends of the target component 300 can be respectively cooperated with the first end and the second end through a locking structure 400. At the same time, a swing rod 10 is provided at each end of the target component 300, and one swing rod 10 is located on the upper side of the target component 300 and the other swing rod 10 is located on the lower side of the target component 300. This ensures that when the connecting rod 20 moves along the first direction L and drives the two swing rods 10 to swing, both swing rods 10 can extend into the unlocking space 500 defined by the two ends of the target component 300 and the two locking structures 400, thereby achieving the unlocking and locking effects.

[0085] In this embodiment, see Figure 8 and Figure 10 Each swing arm 10 is provided with multiple locking parts 11. The multiple locking parts 11 of each swing arm 10 are distributed sequentially along the second direction M. The multiple locking parts 11 can cooperate sequentially with multiple target parts 300 distributed sequentially along the second direction M.

[0086] Multiple locking parts 11 can smoothly engage with multiple target parts 300 sequentially, thereby preventing damage that can easily occur when a single locking part 11 locks multiple target parts 300 simultaneously. Simultaneously, the multiple locking parts 11 protruding from the swing arm 10 further reduce the space occupied by the swing arm 10, allowing it to extend between adjacent groups of target parts 300, thus improving the applicability of the unlocking mechanism 100.

[0087] Specifically, the locking part 11 includes a locking block 111, which is located on the side of the rocker arm 10 and protrudes upward along the third direction N to the top surface of the rocker arm 10, which can better reduce the space occupied by the rocker arm 10.

[0088] In this embodiment, see Figures 2 to 7 The base component 200 includes two spaced plates 210, a connecting rod 20 is located on one side of one plate 210 away from the other plate 210, and a swing rod 10 is located between the two plates 210, with both ends of the swing rod 10 rotatably connected to the two plates 210 respectively.

[0089] The plate 210 is thinner, and the swing arm 10 is rotatably connected between the two plates 210. This can ensure the stable rotation of the swing arm 10 on the base 200, and reduce the space requirements for the rotatable connection between the swing arm 10 and the base 200, so that the unlocking mechanism 100 can be installed in a small space.

[0090] In addition, in this embodiment, multiple target components 300 are arrayed between two plates 210, and the target components 300 are limited and installed, so that the unlocking mechanism 100 makes greater use of the space between the base component 200 and the target components 300.

[0091] In this embodiment, see Figure 5 and Figure 10 The two plates 210 are respectively provided with rotating circular holes 211, and the two ends of the swing rod 10 are respectively provided with mating cylinders 14. The two mating cylinders 14 extend into the rotating circular holes 211 of the two plates 210 respectively. The above structure is simple and easy to achieve a stable rotational connection between the swing rod 10 and the base component 200. Therefore, there is no need to set up additional rotating structures such as bearings, and no need to occupy a lot of extra space. This makes it easy to install the unlocking mechanism 100 in a narrow usage environment.

[0092] In this embodiment, see Figure 7 The base component 200 also includes a base plate 220, which is located on the side of one plate 210 away from the other plate 210. The base plate 220 has a limiting groove 221. The connecting rod 20 also includes a plugging protrusion 24, which is located on the ground of the connecting rod 20 and extends into the limiting groove 221 at an angle between the second direction M and the third direction N. The cooperation between the plugging protrusion 24 and the limiting groove 221 can both limit the movement of the connecting rod 20 in the first direction L and support the connecting rod 20 in the third direction N.

[0093] In this embodiment, see Figure 3 and Figure 5The swing arm 10 is also provided with a limiting protrusion 13. The limiting protrusion 13 is provided on the transmission arm 12 and located on the side of the connecting rod 20 close to the plate 210. The size of the limiting protrusion 13 in the first direction L is larger than the size of the mating groove 21 in the first direction L, so as to restrict the swing arm 10 from falling out between the two plates 210.

[0094] When the connecting rod 20 moves along the first direction L and drives the swing arm 10 to rotate around the second direction M, the force on the swing arm 10 causes the transmission arm 12 to tend to deviate towards the connecting rod 20 in the second direction M. At this time, since the limiting protrusion 13 is sandwiched between the connecting rod 20 and the plate 210, when the swing arm 10 tends to deviate towards the connecting rod 20 in the second direction M, since the size of the limiting protrusion 13 in the first direction L is larger than the size of the mating groove 21 in the first direction L, the connecting rod 20 has a limiting effect on the limiting protrusion 13, thereby ensuring that the connecting rod 20 can stably and reliably drive the swing arm 10 to rotate and achieve the unlocking and locking effects.

[0095] In this embodiment, see Figure 10 The transmission arm 12 includes an extension 121 and a transmission part 122. The extension 121 extends along a third direction N and is located at one end of the rocker arm 10. The transmission part 122 extends along a second direction M and protrudes from the side of the extension 121 away from the rocker arm 10, and engages with the mating groove 21. A limiting protrusion 13 is provided on the transmission part 122. With the above structure, it is easy to realize that the connecting rod 20 drives the rocker arm 10 to rotate.

[0096] In addition, the transmission arm 12 also includes a stop protrusion 123, which protrudes from the side of the extension 121 away from the rocker arm 10. When the rocker arm 10 tends to deviate in the direction of the second direction M toward the connecting rod 20, the stop protrusion 123 can abut against the plate 210, thereby the stop protrusion 123 can also restrict the rocker arm 10 from falling off between the two plates 210.

[0097] In this embodiment, see Figure 7 and Figure 9 One of the connecting rod 20 and the base component 200 is provided with a plurality of sliding protrusions 230, which are distributed along the first direction L. The other is provided with a plurality of sliding grooves 25, which are distributed along the first direction L. Each sliding groove 25 extends along the first direction L, and each sliding protrusion 230 is fitted into a sliding groove 25.

[0098] The cooperation between the sliding protrusion 230 and the sliding groove 25 can guide the movement of the connecting rod 20 on the base member 200 and prevent the connecting rod 20 from moving relative to the base member 200 in the third direction N.

[0099] Specifically, in this embodiment, the sliding protrusion 230 is provided on the base component 200, and the sliding groove 25 is provided on the connecting rod 20, so as to improve the processing efficiency and assembly efficiency of the connecting rod 20, and facilitate the assembly of the connecting rod 20 in a narrow space. Specifically, the base component 200 includes a plate 210, and the sliding protrusion 230 protrudes from the side of the plate 210. Therefore, when the connecting rod 20 is engaged with the plate 210, compared with the existing slide block structure or transmission belt structure, the engagement of the connecting rod 20 and the base component 200 in this embodiment has a smaller space occupation requirement, thereby improving the applicability of the unlocking mechanism 100.

[0100] In addition, see Figure 8 The sliding groove 25 has a large end 251 and a small end 252. When the rocker arm 10 is in the locked state, the sliding protrusion 230 is located at the large end 251, and when the rocker arm 10 is in the unlocked state, the sliding protrusion 230 is located at the small end 252, so as to better ensure the smooth movement of the connecting rod 20.

[0101] In this embodiment, see Figure 7 The mating groove 21 is formed by extending downward from the top surface of the connecting rod 20 along the third direction N.

[0102] With the above structural arrangement, the mating groove 21 has an opening facing upward in the third direction N, which facilitates the mating of the transmission arm 12 into the mating groove 21 when assembling the unlocking mechanism 100, and also facilitates disassembly and assembly during subsequent use. Of course, in other embodiments of the present invention, the mating groove 21 can also be formed as a strip groove on the side of the connecting rod 20, which extends along the third direction N.

[0103] Furthermore, it should be noted that in other embodiments of the present invention, the mating groove 21 may also be provided on the connecting rod 20, and the transmission arm 12 may also be provided on the connecting rod 20. When the transmission arm 12 moves along the first direction L, it can also drive the mating groove 21 to move along the first direction L, thereby causing the swing rod 10 to rotate relative to the base component 200.
