Referring to fig. 1 to 3, the locking structure 100 may include a bracket 10 and a stopper assembly 20. The bracket 10 is intended to be connected to a first external component, said bracket 10 being provided with a runner 11. The limiting assembly 20 includes a limiting element 21 and a sliding element 22 for connecting to the second external member, the sliding element 22 is slidably disposed in the sliding slot 11, and the limiting element 21 is movably disposed on the bracket 10. The sliding member 22 is provided with a first limiting portion 221, and the limiting member 21 is provided with a second limiting portion 211 matched with the first limiting portion 221. It is understood that when the locking structure 100 is applied to a foldable electronic device, the first external member may be a first body 91 of the foldable electronic device, and the second external member may be a second body 92 of the foldable electronic device.

Referring to fig. 1 and 2, the sliding member 22 moves to the first position along the sliding slot 11 of the bracket 10, and the first position-limiting portion 221 is in position-limiting engagement with the second position-limiting portion 211 to lock the bracket 10 and the sliding member 22 to each other. As shown in fig. 3, the sliding member 22 moves to the second position along the sliding slot 11, and the first position-limiting portion 221 is separated from the second position-limiting portion 211, so as to unlock the bracket 10 and the sliding member 22.

Known from the above embodiments, in the locking structure 100 of the present disclosure, the sliding part 22 and the sliding groove 11 are in sliding fit, and through the limit fit of the first limit part 221 and the second limit part 211, the sliding part 22 and the limit part 21 can be locked or separated from each other, so that the sliding part 22 and the bracket 10 can be locked or unlocked from each other, an effective locking function can be realized in a smaller space, when the locking structure is applied to a foldable electronic device, the whole device can have a larger stacking space, the whole device can be more light and thin, and the delicacy of the product can be improved.

In some optional embodiments, one of the first position-limiting portion 221 and the second position-limiting portion 211 comprises a position-limiting groove, and the other of the first position-limiting portion 221 and the second position-limiting portion 211 comprises a position-limiting projection adapted to the position-limiting groove. In this embodiment, the first position-limiting portion 221 includes a position-limiting groove, and the second position-limiting portion 211 includes a position-limiting protrusion. That is, the sliding groove 22 is provided with a limiting groove, and the limiting member 21 is provided with a limiting projection matched with the limiting groove. Of course, in other examples, the first position-limiting portion 221 may include a position-limiting protrusion, and the second position-limiting portion 211 may include a position-limiting groove. That is, the limiting member 21 is provided with a limiting groove, and the sliding groove 22 is provided with a limiting projection matched with the limiting groove. The present disclosure is not so limited.

Referring to fig. 1 and 2, when the sliding member 22 moves to the first position along the sliding groove 11, the limiting protrusion is in clamping fit with the limiting groove, so as to lock the bracket 10 and the sliding member 22 with each other. When the locking structure is applied to the foldable electronic device, the first body 91 and the second body 92 can be locked and fixed to each other when the foldable electronic device is in the unfolded state or the folded state, so that the stability of the foldable electronic device is improved. As shown in fig. 3, the sliding member 22 moves to the second position along the sliding groove 11, and the limiting protrusion is separated from the limiting groove, so as to unlock the bracket 10 and the sliding member 22. When the locking structure is applied to a folding electronic apparatus, the first body 91 and the second body 92 may be separated from each other so that the folding electronic apparatus can be switched between an unfolded state and a folded state.

In some optional embodiments, the position-limiting assembly 20 further includes an elastic member 23, one end (which can be understood as a lower end) of the elastic member 23 away from the sliding member 22 is connected to the bracket 10, and the other end (which can be understood as an upper end) of the elastic member 23 close to the sliding member 22 abuts against the position-limiting member 21. The elastic member 23 can provide the stopper member 21 with an elastic force moving in a direction approaching the slider 22.

As shown in fig. 2 and 3, when the sliding element 22 moves along the sliding slot 11 from the first position to the second position, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding element 22 drives the limiting element 21 to move in a direction away from the sliding element 22, so that the first limiting portion 221 is separated from the second limiting portion 211, thereby separating the sliding element 22 from the bracket 10, and enabling the elastic element 23 to be in a compressed state.

When the sliding member 22 moves along the sliding slot 11 from the second position to the first position, that is, from the state shown in fig. 3 to the state shown in fig. 2, the elastic member 23 moves toward the direction close to the sliding member 22 under the action of the elastic restoring force, and drives the limiting member 21 to move toward the direction close to the sliding member 22 until the sliding member 22 moves to the state shown in fig. 2, so that the first limiting portion 221 and the second limiting portion 211 are in limiting engagement, and the sliding member 22 and the bracket 10 are locked and fixed to each other.

Further, the position limiting assembly 20 may further include a rotating shaft 24 disposed on the bracket 10, one end (shown as a right end in the drawing and indicated as a first end 212) of the position limiting member 21 is pivotally connected to the rotating shaft 24, and the other end 213 (shown as a left end in the drawing and indicated as a second end 213) of the position limiting member 21 is disposed with the second position limiting portion 211. It is understood that the other end (i.e., the upper end) of the elastic element 23 near the sliding element 22 may have an arc-shaped structure and abut against the second end 213 of the limiting element 21.

Referring to fig. 2 and 3, when the sliding element 22 moves along the sliding slot 11 from the first position to the second position, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding element 22 drives the limiting element 21 to rotate relative to the rotating shaft 24 in a direction away from the sliding element 22, so that the first limiting portion 221 is separated from the second limiting portion 211, thereby separating the sliding element 22 from the bracket 10, and enabling the elastic element 23 to be in a compressed state.

When the sliding element 22 moves along the sliding slot 11 from the second position to the first position, that is, from the state shown in fig. 3 to the state shown in fig. 2, the elastic element 23 moves toward the direction close to the sliding element 22 under the action of the elastic restoring force, and drives the limiting element 21 to rotate toward the direction close to the sliding element 22 relative to the rotating shaft 24 until the sliding element 22 moves to the state shown in fig. 2, so that the first limiting portion 221 is in limiting engagement with the second limiting portion 211, and the sliding element 22 and the bracket 10 are locked and fixed to each other.

In some alternative embodiments, the elastic member 23 includes a fixing portion 231 and an elastic portion 232, and the fixing portion 231 is connected to the bracket 10, so as to fix the elastic member 23 to the bracket 10. A first end of the elastic portion 232 is connected to the fixing portion 231, and a second end of the elastic portion 232 extends toward the direction close to the limiting member 21 and abuts against a second end of the limiting member 21. The elastic member 23 can provide the stopper member 21 with an elastic force moving in a direction approaching the slider 22. It is understood that the second end of the elastic portion 232 may have an arc-shaped structure and abut against the second end 213 of the limiting member 21. Alternatively, the fixing portion 231 and the elastic portion 232 may be integrally formed, so as to facilitate the processing and forming.

Referring to fig. 2 and 3, when the sliding element 22 moves along the sliding slot 11 from the first position to the second position, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding element 22 drives the limiting element 21 to rotate relative to the rotating shaft 24 in a direction away from the sliding element 22, so that the first limiting portion 221 is separated from the second limiting portion 211, thereby separating the sliding element 22 from the bracket 10, and can drive the elastic portion 232 of the elastic element 23 to move in a direction close to the fixing portion 231, so that the elastic portion 232 of the elastic element 23 is in a compressed state.

When the sliding element 22 moves from the second position to the first position along the sliding slot 11, that is, from the state shown in fig. 3 to the state shown in fig. 2, the elastic portion 232 of the elastic element 23 moves in a direction away from the fixing portion 231 (that is, in a direction close to the sliding element 22) under the action of the elastic restoring force, so as to drive the limiting member 21 to rotate in a direction close to the sliding element 22 relative to the rotating shaft 24 until the sliding element 22 moves to the state shown in fig. 2, so that the first limiting portion 221 is in limiting engagement with the second limiting portion 211, and thus the sliding element 22 and the bracket 10 are locked and fixed to each other.

In this embodiment, the elastic member 23 may be a spring plate. In another example, the elastic member 23 may be a return spring, the holder 10 may be provided with a receiving cavity, the return spring is received in the receiving cavity, one end of the return spring abuts against the bottom of the receiving cavity, and the other end abuts against the second end 213 of the stopper 21. The functions and effects that the elastic element can realize by adopting the spring piece can also be realized, and the disclosure does not limit the functions and effects.

Further, the bracket 10 may be provided with a fixing member 12, and the fixing portion 231 includes a fastening portion fastened to the fixing member 12, so as to fix the elastic member 23 to the bracket 10. Alternatively, in order to fix the elastic member 23 on the bracket 10 more firmly, the latch portion includes a first latch end 233 and a second latch end 234, the bracket 10 is provided with the mating member 13, and the mating member 13 is spaced apart from the fixing member 12. In the example shown in the figures, the mating member 13 is located below the fixing member 12, and the first catching end 233 is located below the second catching end 234. The engaging element 13 and the fixing element 12 are clamped at two sides of the first fastening portion 233, and the fixing element 12 and the first end 212 of the limiting element 21 are clamped at two sides of the second fastening portion 234, so that the fastening portion of the fixing portion 231 is fixed with the bracket 10 more firmly. Further, the end of the first latching end 233 may further extend outward away from the second latching end 234 to form an extension portion 235, and the extension portion 235 extends downward toward the side of the mating member 13, so as to form a better latching effect with the mating member 13, thereby fixing the latching portion of the fixing portion 231 to the bracket 10 more firmly.

Referring to fig. 4 and 5, in some alternative embodiments, the number of the limiting grooves may be two, and the two limiting grooves are disposed at intervals along the axial direction of the sliding groove 11 on the sliding member 22 or the limiting member 21. The axial direction of the runner 11 is understood to be the opening direction of the runner 11, which is shown as the horizontal direction in the drawing. In the present embodiment, the first position-limiting portion 221 includes a position-limiting groove, and the second position-limiting portion 211 includes a position-limiting protrusion. That is, the sliding slot 22 is provided with a limiting slot, the limiting member 21 is provided with a limiting projection adapted to the limiting slot, for example, two limiting slots are disposed on the sliding member 22 along the axial direction of the sliding slot 11. Of course, in other examples, the first position-limiting portion 221 may include a position-limiting protrusion, and the second position-limiting portion 211 may include a position-limiting groove. That is, the limiting member 21 is provided with a limiting groove, the sliding groove 22 is provided with a limiting projection adapted to the limiting groove, and the two limiting grooves are disposed on the limiting member 21 along the axial direction of the sliding groove 11. The present disclosure is not so limited.

Taking the locking structure applied to the foldable electronic device, fig. 4 shows the foldable electronic device in the unfolded state, and fig. 5 shows the foldable electronic device in the folded state as an example. Referring to fig. 4, when the foldable electronic device is in the unfolded state, the sliding member 22 moves along the sliding slot 11 along the first direction until the limiting protrusion is engaged with one of the limiting grooves (the limiting groove on the right side is shown in fig. 4 and 5) to lock the bracket 10 and the sliding member 22 with each other, so as to lock and fix the first body 91 and the second body 92 of the foldable electronic device with each other, thereby improving the stability of the foldable electronic device. Referring to fig. 5, when the foldable electronic device is folded, the sliding member 22 moves along the sliding groove 11 in a second direction opposite to the first direction until the limiting protrusion is engaged with another limiting groove (the limiting groove on the left side is shown in fig. 4 and 5) to lock the bracket 10 and the sliding member 22, so as to lock and fix the first body 91 and the second body 92 of the foldable electronic device to each other, thereby improving the stability of the foldable electronic device.

As shown in fig. 3, when the foldable electronic device is switched between the unfolded state and the folded state, the sliding member 22 moves along the sliding groove 11 until the limiting projection is separated from the corresponding limiting groove, so as to unlock the bracket 10 and the sliding member 22, thereby separating the first body 91 and the second body 92 from each other, so that the foldable electronic device can be switched between the unfolded state and the folded state.

In some optional embodiments, the limiting groove is a trapezoidal groove, and the limiting protrusion is in a trapezoidal structure matched with the shape of the limiting groove. The size of the opening of the limiting groove is larger than that of the bottom wall of the limiting groove. Correspondingly, the size of the end part of the limiting lug close to one side of the limiting groove is smaller than the size of the end part of the limiting lug far away from one side of the limiting groove so as to be matched with the limiting groove. The limit groove and the limit lug adopt the trapezoidal groove and the trapezoidal structure which are matched with each other, so that a better clamping matching effect can be achieved, and the limit groove and the limit lug can be better mutually pushed through the inclined plane matching during mutual movement.

Referring to fig. 2 and 3, when the sliding element 22 moves along the sliding slot 11 from the first position to the second position, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding element 22 slides leftwards along the sliding slot 11, and the inner sidewall of the limiting slot pushes the limiting protrusion of the limiting element 21 through the inclined surface, so as to drive the limiting element 21 to rotate in the direction away from the sliding element 22 relative to the rotating shaft 24, and it is known that the limiting protrusion is separated from the limiting slot.

When the sliding member 22 moves from the second position to the first position along the sliding groove 11, that is, from the state shown in fig. 3 to the state shown in fig. 2, the sliding member 22 slides rightward along the sliding groove 11, and when the sliding member 22 slides to a position where the limiting groove corresponds to the limiting projection of the limiting member 21, the elastic member 23 drives the limiting member 21 to rotate in a direction close to the sliding member 22 relative to the rotating shaft 24, so that the limiting projection of the limiting member 21 is clamped in the limiting groove of the sliding member 22.

Further, in order to achieve better and smoother effects when the bracket 10 and the slider 22 are switched between the locking state and the unlocking state, an inwardly recessed first arc-shaped portion is formed on the peripheral side of the bottom wall of the limiting groove, and a second arc-shaped portion matched with the first arc-shaped portion is formed on the peripheral side of one end, close to the slider 22, of the limiting convex block. Spacing groove and spacing lug can cooperate more smoothly when butt each other or promote through the cooperation of first arc portion and second arc portion to reach better more smooth effect.

In some alternative embodiments, the bracket 10 may be provided with at least one mounting hole 14, which may be fixedly engaged with a first external member by a fastener such as a screw, to mount the bracket 10 to the first external member. In this embodiment, the upper portion of the bracket 10 is provided with two mounting holes 14, and the lower portion of the bracket 10 is provided with one mounting hole 14. It should be noted that, the positions and the number of the mounting holes 14 can be set according to actual needs, and the disclosure does not limit this.

Referring to fig. 6 to 8, an embodiment of the present disclosure further provides a foldable electronic device 200, including: a first body 91, a second body 92 and a locking structure.

The second body 92 and the first body 91 can be folded and connected, and when the second body 92 is folded and connected with respect to the first body 91, the sliding part of the locking structure is driven to slide along the sliding groove, so that the first position and the second position are switched. It will be appreciated that the locking structure is provided inside the housing of the folding electronic device and is therefore not shown in fig. 6 to 8. The bracket of the locking structure can be mounted on the first body through a mounting hole matched with a fastener such as a screw, and the sliding piece can also be mounted on the second body in a similar mode. Both the first body and the second body may be understood as a structure having a display screen. The folding electronic device can be a folding mobile phone, a folding tablet, a folding computer and other electronic devices.

As shown in fig. 6, when the foldable electronic device 200 is in the unfolded state, the locking structure may be the state shown in fig. 4, that is, the sliding member and the bracket are locked and fixed to each other, so as to lock and fix the first body 91 and the second body 92 to each other.
