Fig. 2 schematically shows a partially cut-away structure of the storage case 10 in a closed-lid state according to an embodiment of the present application. Referring to fig. 2, the storage case 10 according to an embodiment of the present application may include a first case 11 and a second case 12. The first case 11 and the second case 12 may form a receiving chamber for receiving the wireless earphone. Illustratively, one of the first and second cases 11 and 12 may serve as a case body, and the other may serve as a case cover. The embodiment of the present application will be described taking the first case 11 as an example of a case cover. The first case 11 and the second case 12 may be connected by a hinge 20 according to an embodiment of the present application, so that the first case 11 may be turned with respect to the second case 12 to be switched between a closed position and an open position. The first container 11 is shown in the closed position in fig. 2. Fig. 3 schematically shows a partial structure of the storage case 10 in an open state according to the embodiment of the present application. Referring to fig. 3, the first casing 11 is turned over a predetermined angle with respect to the second casing 12, and at this time, the first casing 11 is in the open position.

When the first case 11 and the second case 12 are separated from each other from the closed state and the first case 11 is turned over to stop the rotation, the first case 11 is in the open position. When the first casing 11 and the second casing 12 are moved closer to each other from the open state and the first casing 11 is turned over to stop the rotation, the first casing 11 is in the closed position.

The hinge 20 in the embodiment of the present application includes a spindle 21 and a sleeve 22. The hinge 20 can be connected to two structural parts to be covered or uncovered by the spindle 21 and the sleeve 22, respectively, i.e. to one of the structural parts by the spindle 21 and to the other structural part by the sleeve 22. Referring to fig. 3, one of the two structural members is taken as a first box 11, and the other structural member is taken as a second box 12, which is taken as an example to describe the embodiment of the present application, but the protection scope of the present application is not limited. The hinge 20 may be connected to the first and second cases 11 and 12 by a spindle 21 and a sleeve 22, respectively.

Fig. 4 schematically shows a partial structure of the hinge 20 according to an embodiment of the application in a first state. Fig. 5 schematically shows a partial structure of the hinge 20 according to an embodiment of the present application in a second state. Referring to fig. 4 and 5, a spindle 21 of the hinge 20 is disposed within a sleeve 22. The sleeve 22 of the hinge 20 is rotatably sleeved on the mandrel 21. In some embodiments, sleeve 22 is sleeved outside mandrel 21. The mandrel 21 is inserted into the central hole of the sleeve 22. In some examples, the mandrel 21 may be threaded out of the sleeve 22 such that opposite ends of the mandrel 21 are respectively exposed to the sleeve 22. The sleeve 22 is switchable between a first locking position and a second locking position when the sleeve 22 rotates relative to the spindle 21. The first locking position and the second locking position may refer to two extreme positions when the sleeve 22 rotates relative to the spindle 21. Illustratively, the sleeve 22 is shown in fig. 2 or 4 in a first locked position, while the spindle 21 is in a first position. The sleeve 22 is shown in fig. 3 or 5 in the second locking position, while the spindle 21 is in the second position. The first position and the second position may refer to two extreme positions when the spindle 21 moves in the axial direction X of the sleeve 22.

The spindle 21 of the hinge 20 is in sliding engagement with the sleeve 22. Along the axial direction X of the sleeve 22, the spindle 21 may slide relative to the sleeve 22, i.e. when the spindle 21 is subjected to a force along the axial direction X of the sleeve 22, the spindle 21 may slide relative to the sleeve 22, whereby the dimension of the spindle 21 extending out of the sleeve 22 may be varied. The entire spindle 21 is switchable between a first position and a second position when the spindle 21 slides relative to the sleeve 22. When the sleeve 22 is in the first locking position, the spindle 21 is in the first position. When the sleeve 22 is in the second locking position, the spindle 21 is in the second position.

The rotation of the sleeve 22 and the sliding of the mandrel 21 are kept synchronous, namely, when the sleeve 22 rotates, the mandrel 21 synchronously slides; alternatively, when the mandrel 21 slips, the sleeve 22 rotates synchronously. When the sleeve 22 is switched from the first lock position to the second lock position, the spindle 21 slides from the first position to the second position. When the sleeve 22 is switched from the second lock position to the first lock position, the spindle 21 slides from the second position to the first position.

The hinge 20 of the present embodiment may be used to connect two structural members that need to be opened or closed to each other. One of the two structural members is connected to the sleeve 22 and the other is connected to the mandrel 21. When the two structural members are switched from the closed state to the open state, the spindle 21 of the hinge 20 slides and is switched from the first position to the second position, while the sleeve 22 of the hinge 20 rotates and is switched from the first locking position to the second locking position. When the two structural members are switched from the open state to the closed state, the sleeve 22 of the hinge 20 is rotated and switched from the second locking position to the first locking position, and the spindle 21 of the hinge 20 is slipped and switched from the second position to the first position. Both the mandrel 21 and the sleeve 22 may be interlocked during the closing or opening of the structure. The mandrel 21 of the hinge 20 and the sleeve 22 can form a limit in the sliding process, so that the mandrel 21 is prevented from loosening, and therefore, the structural member can stably move in the closing or opening process, and the possibility of impact of the structural member in the closing or opening process is reduced.

In some implementations, the hinge 20 also includes a drive assembly. The spindle 21 and the sleeve 22 can transmit power through a transmission assembly, so that the sliding of the spindle 21 and the rotation of the sleeve 22 are synchronized. Referring to fig. 5, the transmission assembly may include a guide pin 24 and a screw guide 25. The guide pin 24 is slidably fitted with the screw guide 25. One of the guide pin 24 and the screw guide 25 is provided on the spindle 21, and the other is provided on the sleeve 22. The spiral guide 25 extends in the axial direction X of the sleeve 22. The spiral guide portion 25 has a spiral guide surface. The guide pin 24 may be in contact with a helical guide surface. The guide pin 24 is movable relative to the helical guide surface when the spindle 21 is slid and the sleeve 22 is rotated. By adopting the matching mode of the guide pin 24 and the spiral guide part 25, the guide pin 24 and the spiral guide part 25 can form limit constraint with each other, and the sliding process of the guide pin 24 relative to the spiral guide part 25 has no impact, thereby being beneficial to ensuring stable power transmission between the mandrel 21 and the sleeve 22.

The force between the guide pin 24 and the helical guide 25 may form a component force in the axial direction X of the sleeve 22 and a component force in a direction perpendicular to the axial direction X of the sleeve 22. A component of force in a direction perpendicular to the axial direction X of the sleeve 22 may cause the sleeve 22 to generate a rotational moment. Therefore, the magnitude of the rotational moment generated by the sleeve 22 can be adjusted by adjusting the helix angle of the helical guide 25.

In some examples, referring to fig. 3, sleeve 22 may be coupled to first cartridge 11, with spindle 21 disposed on second cartridge 12. The guide pin 24 is provided to the spindle 21, and the screw guide 25 is provided to the sleeve 22. In some examples, the first locking position and the second locking position are located at both ends of the spiral guide portion, respectively, in a spiral direction of the spiral guide portion 25. Referring to fig. 3 and 5, the first container 11 is shown in an open position, in which the sleeve 22 is in the second, locked position and the spindle 21 is in the second position. The guide pin 24 and the screw guide 25 can be kept in contact.

When the first container 11 is switched from the open position to the closed position, the sleeve 22 rotates in the direction Y shown in fig. 3 or 5, and the spindle 21 slides in the axial direction X of the sleeve 22. The guide pin 24 and the screw guide 25 can be kept in contact. The mandrel 21 may not rotate itself during the sliding process. Referring to fig. 2 and 4, the sleeve 22 stops rotating when it rotates to the first locking position. At this time, the spindle 21 is located at the first position, and the first case 11 is located at the covering position.

When the first casing 11 is switched from the closed position to the open position, the sleeve 22 rotates in a direction opposite to the direction Y, while the sleeve 22 drives the spindle 21 to slide in the axial direction X of the sleeve 22 via the screw guide 25. The mandrel 21 may not rotate itself during the sliding process. The guide pin 24 and the screw guide 25 can be kept in contact. Referring to fig. 3 and 5, rotation of the sleeve 22 to the second locking position is stopped. At this time, the spindle 21 is in the second position, and the first case 11 is in the open position.

In some examples, referring to fig. 5, the helical guide 25 may be a guide hole. The guide pin 24 may be a columnar structure. For example, the guide pin 24 may be of cylindrical configuration. At least part of the guide pin 24 may be located within the helical guide 25. Illustratively, the helical guide 25 may be a blind hole. The opening of the spiral guide 25 is provided toward the spindle 21. The screw guide 25 may be a through hole penetrating the sleeve 22 in the radial direction of the sleeve 22, for example.

Illustratively, the spindle 21 and the guide pin 24 may be a split assembly structure. The spindle 21 and the guide pin 24 are manufactured separately from each other. The screw guide 25 may be a through hole penetrating the sleeve 22. The mandrel 21 is inserted into the central hole of the sleeve 22 in advance. The guide pin 24 is then passed through the helical guide 25 and connected to the spindle 21. Illustratively, the spindle 21 and guide pin 24 may be threaded or welded.

Illustratively, FIG. 6 schematically illustrates a partial cross-sectional configuration of a hinge 20 in accordance with an embodiment of the present application. Referring to fig. 6, the spindle 21 and the guide pin 24 may be of unitary construction. The sleeve 22 includes a barrel body 221 and a stop ring 222. The spiral guide 25 may be a guide hole. The guide holes extend in the axial direction X of the sleeve 22. From one side of the cartridge body 221, the guide pin 24 of the spindle 21 is aligned with the guide hole, and then the spindle 21 and the guide pin 24 are moved in the axial direction X of the sleeve 22 so that the guide pin 24 enters the guide hole. A stop ring 222 is fitted over the spindle 21. The stop ring 222 is connected to the cartridge body 221 to reduce the likelihood of the guide pin 24 backing out of the guide bore along the axial direction X of the sleeve 22.

In some examples, fig. 7 schematically illustrates a partial structure of a hinge 20 according to an embodiment of the present application. Referring to fig. 7, the spiral guide 25 may be a guide rib. The sleeve 22 includes a barrel body 221 and a stop ring 222. The guide rib is provided on the inner wall of the cylinder body 221. The guide rib extends in the axial direction X of the sleeve 22. From one side of the cartridge body 221, the guide pin 24 of the spindle 21 is aligned with the guide rib, and then the spindle 21 and the guide pin 24 are moved in the axial direction X of the sleeve 22 so that the guide pin 24 enters the cartridge body 221 and cooperates with the guide rib. A stop ring 222 is fitted over the spindle 21. The stop ring 222 is coupled to the cartridge body 221 to reduce the likelihood of the guide pin 24 backing out of the cartridge body 221 along the axial direction X of the sleeve 22.

Referring to fig. 7, the guide pin 24 and the guide rib may be accommodated in the sleeve 22, so that on one hand, the relative sliding smoothness and stability between the guide pin 24 and the guide rib may be affected by the entry of sundries or dust into the guide pin 24 and the guide rib; on the other hand, the sleeve 22 shields the guide pin 24 and the guide rib, which is beneficial to improving the appearance neatness of the sleeve 22 and improving the aesthetic degree of the hinge 20.

In some implementations, FIG. 8 schematically illustrates a partial cross-sectional configuration of hinge 20 in accordance with an embodiment of the present application. Referring to fig. 8, the hinge 20 further includes rolling bodies. The rolling bodies 26 are arranged between the sleeve 22 and the mandrel 21, so that rolling friction can be formed between the mandrel 21 and the sleeve 22 through the rolling bodies 26, sliding resistance or sliding noise of the mandrel 21 can be reduced, and stability of the mandrel 21 in the sliding process or the sleeve 22 in the rotating process can be further improved. In some examples, rolling elements 26 are provided on the inner wall of the sleeve 22. Illustratively, a plurality of sets of rolling elements 26 may be disposed on an inner wall of the sleeve 22. The plurality of sets of rolling elements 26 are disposed side by side along the axial direction X of the sleeve 22. Each set of rolling elements 26 includes more than three rolling elements 26. More than three rolling elements 26 are arranged around the spindle 21. The rolling bodies 26 may be balls, for example. The sleeve 22 is provided with holes extending radially of itself. The balls are placed in the holes. A fixing member (not shown) is connected to the sleeve 22 to fix the balls by the fixing member. For example, the securing member may be threadably coupled to the sleeve 22.

In some implementations, referring to fig. 4 and 8, the guide pin 24 includes a post 241 and a ring 242. The ring 242 is rotatably sleeved on the cylinder 241. The cylinder 241 of the guide pin 24 may be coupled to the spindle 21. The guide pin 24 may be engaged with the screw guide 25 through the ring 242. Since the ring 242 can rotate around the cylinder 241, the guide pin 24 can form rolling friction between the ring 242 and the spiral guiding portion 25, so as to reduce sliding resistance or sliding noise of the guide pin 24, and further improve stability of the sliding process of the guide pin 24 or the rotating process of the sleeve 22.

In some examples, a rolling bearing is sleeved on cylinder 241. The outer race of the rolling bearing forms a ring body 242.

In some examples, hinge 20 further includes a limit boss 27. A limit boss 27 may be provided on the screw guide 25. The limit boss 27 extends in the spiral direction of the spiral guide 25. The limiting boss 27 is located on a side of the ring 242 facing away from the top end of the cylinder 241. The limiting boss 27 is used for forming limiting constraint on the ring body 242 in the axial direction of the cylinder 241, so that the possibility that the ring body 242 moves along the axial direction of the cylinder 241 to cause the ring body 242 to be out of contact with the spiral guide portion 25 is reduced.

In some implementations, referring to fig. 4 and 5, the spiral guide 25 has a first detent 251 and a second detent 252. The first positioning groove 251 and the second positioning groove 252 are provided at intervals along the spiral direction of the spiral guide portion 25. In some examples, the shape of the guide pin 24 matches the shape of the first detent 251 or the shape of the second detent 252. When the sleeve 22 is in the first locking position, the guide pin 24 enters the first positioning groove 251 to be engaged with the first positioning groove 251. The guide pin 24 is not easily removed from the first positioning groove 251 so that the spindle 21 is maintained in the first position, and the first case 11 is maintained in the capping position. The first case 11 is not easily opened by shaking and causes scattering of the stored articles. When the sleeve 22 is in the second locking position, the guide pin 24 enters the second detent 252 to mate with the second detent 252. The guide pin 24 is not easily removed from the second positioning groove 252 so that the spindle 21 is maintained in the second position while the first case 11 is maintained in the open position. The first box 11 is difficult to loose and shake or re-cover relative to the second box 12, so that the possibility of inconvenient article taking caused by the fact that the first box 11 is difficult to keep in an open position is reduced. When the sleeve 22 is forced to rotate relative to the mandrel 21, the guide pin 24 can be disengaged from the first positioning groove 251 or the second positioning groove 252.

In some examples, the first detent 251 and the second detent 252 are located on the same helical guide surface of the helical guide 25.

In some examples, the guide pin 24 includes a ring 242. Ring 242 may be of annular configuration. The surfaces of the first and second positioning grooves 251 and 252 may each have a circular arc shape.

In some examples, the first and second detents 251, 252 may be disposed through the sleeve 22, respectively, in a radial direction of the sleeve 22.

In some implementations, referring to fig. 4 and 5, the hinge 20 further includes a connection tab 28. The coupling boss 28 is provided on the outer wall of the sleeve 22 to facilitate coupling of the sleeve 22 to other structural members. The connecting lugs 28 serve to connect the sleeve 22 to an external structural member. For example, the connection protrusion 28 is used to connect the sleeve 22 and the first case 11. In some examples, the connection protrusion 28 may be adhesively connected with the first case 11. For example, the connection protrusion 28 and the first case 11 may be bonded using an adhesive. In some examples, a groove (not shown in the figures) is provided on the end face of the first casing 11 facing the second casing 12. The connection protrusion 28 is inserted into the groove and adhered to the first case 11.

In some examples, the connection protrusion 28 is disposed on an outer peripheral surface of the sleeve 22. The number of the connection protrusions 28 may be two or more. More than two connecting projections 28 may be provided at intervals along the axial direction X of the sleeve 22. Illustratively, the number of grooves on the first casing 11 is the same as the number of connecting protrusions 28. In the above two connection convex parts 28, the orthographic projection areas of at least two connection convex parts 28 along the radial direction of the sleeve 22 can be different, so that the correct installation position of the sleeve 22 can be judged through the sizes of the connection convex parts 28 and the grooves, and the assembly difficulty or the possibility of error in the assembly process can be reduced.

In some implementations, referring to fig. 4 and 8, the mandrel 21 includes a slip fit portion 211 and a stop portion 212 that are connected. The sleeve 22 is rotatably sleeved on the sliding fit portion 211. Illustratively, the slip fit portion 211 of the mandrel 21 may be a cylindrical section, while the central bore of the sleeve 22 may be a circular bore. Along the axial direction X of the sleeve 22, the stopper 212 of the spindle 21 is located outside the sleeve 22. The rotation of the spindle 21 relative to the sleeve 22 can be restricted by the restricting portion 212. When the mandrel 21 is slidably connected with an external structural member, the external structural member limits the mandrel 21 through the limiting part 212 of the mandrel 21, so that the possibility that the mandrel 21 rotates relative to the sleeve 22 is reduced.

In some examples, the limiting portion 212 is disposed beyond the edge of the central hole of the sleeve 22 in the radial direction of the sleeve 22, so that when the mandrel 21 slides relative to the sleeve 22, the limiting portion 212 of the mandrel 21 can press against the sleeve 22 to reduce the possibility of the mandrel 21 backing out of the sleeve 22. The radial direction of the sleeve 22 is perpendicular to the axial direction of the sleeve 22. The limiting portion 212 and the sliding engagement portion 211 of the spindle 21 may be a split assembly structure. After the sleeve 22 is fitted over the slip fit portion 211 of the mandrel 21, the stopper 212 and the slip fit portion 211 are connected. Illustratively, the limit portion 212 may be screwed or welded with the slip fit portion 211.

In some examples, fig. 9 schematically illustrates a partially exploded structure of the case 10 of an embodiment of the present application. Referring to fig. 2 and 9, the second case 12 includes a guide chute 100. Along the axial direction X of the sleeve 22, the guide chute 100 is larger in size than the spindle 21, so that the spindle 21 can slide in the guide chute 100 along the axial direction X of the sleeve 22. The mandrel 21 is located in the guide chute 100, so that the space occupation rate of the mandrel 21 can be reduced, and the appearance of the storage box 10 can be tidy.

Illustratively, the limit 212 of the spindle 21 may be a sliding fit with the guide chute 100. The shape of the stopper 212 of the spindle 21 may be matched to the shape of the guide chute 100. The second box 12 can limit the rotation of the mandrel 21 relative to the sleeve 22 through the limiting part 212, so that the mandrel 21 is not easy to rotate relative to the guide chute 100. Illustratively, the cross-section of the stop 212 of the spindle 21 may be polygonal, for example, may be quadrilateral or pentagonal. Illustratively, the guide chute 100 has an opening facing the first box 11. The spindle 21 can be placed through the opening into the guide chute 100.

In some examples, a relief notch is provided on the second cassette 12. The guide chute 100 communicates with the avoidance gap. The guide sliding grooves 100 are respectively arranged on two sides of the avoidance gap along the axial direction X of the sleeve 22. At least a portion of the sleeve 22 is received within the relief notch.

In some examples, the end of the mandrel 21 is provided with a stop 212. Illustratively, along the axial direction X of the sleeve 22, the opposite ends of the slip fit portion 211 may be provided with stopper portions 212, respectively. When the core shaft 21 is slidably engaged with the guide chute 100 through the limiting portions 212 disposed at the opposite ends of the sliding engaging portion 211, the possibility of the core shaft 21 swinging in the guide chute 100 can be reduced, and the stability of the core shaft 21 sliding in the guide chute 100 can be improved.

In some implementations, the hinge 20 further includes an energy storage member 23. The energy accumulating member 23 is connected to the spindle 21. The mandrel 21 may cause the energy storage member 23 to store energy or release energy when the mandrel 21 slides relative to the sleeve 22. The energy storage member 23 can apply a force to the mandrel 21 in the axial direction X of the sleeve 22.

When the hinge 20 is connected to the structure, the spindle 21 of the hinge 20 can be slidably connected to the structure, and the energy storage member 23 of the hinge 20 is also provided on the structure. The sleeve 22 of the hinge 20 is connected to another structural member such that the structural member and the sleeve 22 can be rotated synchronously about the spindle 21.

Illustratively, referring to fig. 2, the sleeve 22 is in the first locked position and the mandrel 21 is in the first position with the two structural members in a mutually overlapping condition. Referring to fig. 3, the sleeve 22 is in the second locking position and the spindle 21 is in the second position, with the two structural members open to each other.

In the process of covering or opening the structural member, the mandrel 21, the sleeve 22 and the energy storage component 23 can be linked. The mandrel 21, the sleeve 22 and the energy storage member 23 may be restrained by each other. The energy storage part 23 has better stability in the process of energy storage or energy release, so that the stability in the movement process between the mandrel 21 and the sleeve 22 is also better, and the situation of abrupt stress change between the mandrel 21 and the sleeve 22 is not easy to occur.

In some examples, an energy storage member 23 may be provided at one end of the mandrel 21 along the axial direction X of the sleeve 22. Alternatively, the energy accumulating members 23 may be provided at both ends of the mandrel 21, respectively.

In some examples, referring to fig. 3, an energy storage member 23 may be provided at one end of the mandrel 21. The sleeve 22 may be connected to the first casing 11, while the spindle 21 and the energy accumulating member 23 are arranged in the second casing 12. The guide pin 24 is provided to the spindle 21, and the screw guide 25 is provided to the sleeve 22. Referring to fig. 3 and 5, when the first case 11 is in the open position, the sleeve 22 is in the second locking position, and the spindle 21 is in the second position, while the energy storage member 23 stores energy. Under the action of the energy storage member 23, the guide pin 24 is pressed against the spiral guide portion 25, so that the guide pin 24 and the spiral guide portion 25 can be ensured to maintain a contact state.

When the first casing 11 is switched from the open position to the closed position, the sleeve 22 rotates in the direction Y shown in fig. 3 or 5, while the energy accumulating member 23 releases energy, which can drive the spindle 21 to slide along the axial direction X of the sleeve 22. The guide pin 24 and the screw guide 25 can be kept in contact. When the spindle 21 slides in the axial direction X of the sleeve 22, the dimension of the spindle 21 protruding on the side of the sleeve 22 facing away from the energy storage member 23 becomes larger, while the dimension of the spindle 21 protruding on the side of the sleeve 22 facing the energy storage member 23 becomes smaller. The mandrel 21 may not rotate itself during the sliding process. Referring to fig. 2 and 4, the sleeve 22 stops rotating when it rotates to the first locking position. At this time, the spindle 21 is located at the first position, and the first case 11 is located at the covering position.

When the first casing 11 is switched from the closed position to the open position, the sleeve 22 rotates in a direction opposite to the direction Y, while the sleeve 22 can drive the spindle 21 to slide in the axial direction X of the sleeve 22 via the screw guide 25. When the spindle 21 slides in the axial direction X of the sleeve 22, the dimension of the spindle 21 protruding on the side of the sleeve 22 facing away from the energy storage member 23 becomes smaller, and the dimension of the spindle 21 protruding on the side of the sleeve 22 facing the energy storage member 23 becomes larger. The mandrel 21 may not rotate itself during the sliding process. The spindle 21 applies work to the energy storage member 23 to cause the energy storage member 23 to store energy. The guide pin 24 and the screw guide 25 can be kept in contact. Referring to fig. 3 and 5, rotation of the sleeve 22 to the second locking position is stopped. At this time, the spindle 21 is in the second position, and the first case 11 is in the open position.

In some implementations, the second cartridge 12 includes a guide chute 100. Both the spindle 21 and the energy storage member 23 are located within the guide chute 100. The spindle 21 can slide in the axial direction X in the guide chute 100 in order to store energy in the energy storage means 23 or to release energy.

In some examples, the energy storage component 23 includes an elastic member. Both the spindle 21 and the elastic element are located in the guide chute 100. The spindle 21 slides relative to the sleeve 22 to cause the spring to accumulate energy or release energy.

In some examples, when the first casing 11 is switched from the open position to the closed position, the sleeve 22 rotates in the direction Y shown in fig. 3 or 5, while the elastic element can release energy, driving the spindle 21 to slide along the axial direction X of the sleeve 22. Under the limit constraint of the elastic member, the guide pin 24 is kept in contact with the spiral guide portion 25. When the sleeve 22 is rotated to the first locking position, the rotation is stopped. At this time, the spindle 21 is located at the first position, and the first case 11 is located at the covering position.

When the first casing 11 is switched from the closed position to the open position, the sleeve 22 rotates in a direction opposite to the direction Y, while the sleeve 22 drives the spindle 21 to slide in the axial direction X of the sleeve 22 via the screw guide 25. The mandrel 21 applies work to the elastic member so that the elastic member is compressively deformed to accumulate energy. Under the limit constraint of the elastic member, the guide pin 24 is kept in contact with the spiral guide portion 25. When the sleeve 22 is rotated to the second locking position, the rotation is stopped. At this time, the spindle 21 is in the second position, and the first case 11 is in the open position.

In some examples, an elastic member may be provided at one end of the mandrel 21 along the axial direction X of the sleeve 22.

In other examples, elastic members may be provided at both ends of the mandrel 21 along the axial direction X of the sleeve 22, respectively. One of the two elastic members can release energy when the other elastic member stores energy. For example, one elastic member may be in a compressed state and the other elastic member may be in a stretched state. The two elastic members respectively apply a force to the mandrel 21 in the axial direction X of the sleeve 22, so that the smoothness of the sliding process of the mandrel 21 can be improved.

In some examples, a guide chute 100 is provided on the end face of the second casing 12 facing the first casing 11. Alternatively, the second case 12 includes a projection (not shown) projecting outwardly away from the receiving cavity. The guide chute 100 is provided on the projection. The opening of the guide chute 100 faces the first casing 11. Alternatively, the second case 12 includes a projection projecting inward toward the receiving chamber. The guide chute 100 is provided on the projection. The opening of the guide chute 100 faces the first casing 11.

In some implementations, referring to fig. 9, the case 10 further includes a cover 13. The cover 13 is connected to the second casing 12. The cover 13 covers the guide chute 100 and can limit the mandrel 21, reducing the possibility that the mandrel 21 and the energy storage member 23 are withdrawn from the guide chute 100 and disconnected from the second housing 12. The cover 13 shields the mandrel 21 and the energy storage member 23, and can improve the appearance cleanliness of the storage case 10. The shape of the inner surface of the cover 13 may match the shape of the stopper 212 of the spindle 21. Illustratively, the cover 13 may be adhered to the second case 12.

In some examples, the energy storage component 23 includes an elastic member. When the elastic member is disposed in the guide chute 100, one end of the elastic member is connected to the end surface of the mandrel 21 facing away from the sleeve 22, and the other end is connected to the inner wall of the guide chute 100.

The elastic member may be a coil spring, for example. Fig. 10 schematically shows a partially cut-away configuration of a hinge 20 according to an embodiment of the application. Referring to fig. 10, the hinge 20 may further include a positioning post 29. The elastic member is sleeved on the positioning column 29. One end of the positioning post 29 may be connected to the mandrel 21, or one end of the positioning post 29 may be connected to the second case 12. The positioning column 29 can play a role in positioning the elastic member, thereby being beneficial to improving the accuracy of the mounting position of the elastic member. Meanwhile, when the elastic member is bent due to unbalanced stress, the positioning column 29 can restrict the elastic member, so that the possibility that the elastic member is bent to be ejected from the guide chute 100 or is not easy to recover is reduced.

The elastic member may be an elastomer made of rubber or silica gel.

In some implementations, the hinge 20 includes a spindle 21, a sleeve 22, and an energy storage member 23. The sleeve 22 is provided with a helical guide 25 extending along the axial direction X of the sleeve 22. The spiral guide portion 25 is a guide hole. The sleeve 22 has a first locking position and a second locking position. Along the spiral direction of the spiral guide portion 25, the first locking position and the second locking position are located at both ends of the spiral guide portion 25, respectively. The spindle 21 is provided with a guide pin 24. The mandrel 21 is disposed within the sleeve 22. The guide pin 24 is retained in the screw guide 25. When the sleeve 22 rotates relative to the spindle 21, the guide pin 24 is movable within the screw guide 25 such that the guide pin 24 can be switched between a first locking position at one end of the screw guide 25 and a second locking position at the other end of the screw guide 25, while the spindle 21 slides within the sleeve 22 in the axial direction X of the sleeve 22.

The energy accumulating member 23 is connected to the spindle 21. The energy storage member 23 is provided at one end of the spindle 21. Wherein the sleeve 22 rotates relative to the spindle 21 such that upon switching of the first and second locking positions, the guide pin 24 moves within the helical guide 25 and the spindle 21 slides in the axial direction X relative to the sleeve 22 to cause the energy storage member 23 to store energy or release energy.

In other possible embodiments, the sleeve 22 of the hinge 20 may be connected to the first casing 11, while the spindle 21 of the hinge 20 and the energy storage member 23 are provided in the second casing 12. The screw guide 25 may be provided to the spindle 21, and the guide pin 24 may be provided to the sleeve 22, so that the hinge 20 of the present embodiment can also achieve power transmission between the spindle 21 and the sleeve 22, so that the sliding of the spindle 21 and the rotation of the sleeve 22 are synchronized.

The first body 31 and the second body 32 may be connected by the hinge 20 according to the embodiment of the present application, so that the first body 31 may be turned with respect to the second body 32 to be switched between the closed position and the open position. When the first body 31 and the second body 32 are away from each other from the closed state and the first body 31 is turned over to stop the rotation, the first body 31 is in the open position. When the first body 31 and the second body 32 are close to each other from the open state and the first body 31 is turned over to stop the rotation, the first body 31 is in the closed position.

Referring to fig. 13, the hinge 20 according to the embodiment of the present application may be connected to the first body 31 and the second body 32 through the core shaft 21 and the sleeve 22, respectively.

In some examples, the mandrel 21 includes a slip fit portion 211 and a stop portion 212 that are connected. The sleeve 22 is rotatably sleeved on the sliding fit portion 211. The limiting portion 212 of the mandrel 21 is in sliding fit with the guide chute 100. The shape of the limit portion 212 of the spindle 21 may be matched to the shape of the guide chute 100, so that the limit portion 212 of the spindle 21 may slide within the guide chute 100. The second body 32 limits the rotation of the mandrel 21 relative to the sleeve 22 through the limiting portion 212, so that the mandrel 21 is not easy to rotate relative to the guide chute 100.

In some examples, the sleeve 22 rotates in the direction Y shown in fig. 5 when the first body 31 is switched from the open position to the closed position. The guide pin 24 is kept in contact with the screw guide 25. When the sleeve 22 is rotated to the first locking position, the rotation is stopped.

The frame plate 321 is disposed facing the first body 31. The frame plate 321 may cover the guide chute 100 and may form a limit for the spindle 21 and the sleeve 22, reducing the possibility of the spindle 21 and the sleeve 22 being withdrawn from the guide chute 100 out of connection with the second body 32. The frame plate 321 shields the cover spindle 21 and the sleeve 22, and can improve the appearance cleanliness of the electronic device 30. The shape of the inner surface of the frame plate 321 may match the shape of the stopper 212 of the spindle 21. Illustratively, the frame plate 321 may be bonded to the second body 32.

In some implementations, the hinge 20 further includes an energy storage member 23. The energy accumulating member 23 is connected to the spindle 21. The mandrel 21 may cause the energy storage member 23 to store energy or release energy when the mandrel 21 slides relative to the sleeve 22. The energy accumulating member 23 may apply a force to the spindle 21 in the axial direction X of the sleeve 22.

In some implementations, the energy storage member 23 of the hinge 20 may be provided to the second body 32. The second body 32 includes a guide chute 100. Both the spindle 21 and the energy storage member 23 are located in the guide chute 100.

In some examples, an energy storage member 23 may be provided at one end of the mandrel 21 along the axial direction X of the sleeve 22. When the first body 31 is switched from the open position to the closed position, the sleeve 22 rotates in the direction Y shown in fig. 5, while the energy accumulating member 23 can release energy, driving the spindle 21 to slide along the axial direction X of the sleeve 22. The guide pin 24 may be kept in contact with the screw guide 25. When the sleeve 22 is rotated to the first locking position, the rotation is stopped. At this time, the mandrel 21 is located at the first position, and the first body 31 is located at the covering position.

When the first body 31 is switched from the closing position to the opening position, the sleeve 22 rotates in a direction opposite to the direction Y, while the sleeve 22 drives the spindle 21 to slide in the axial direction X of the sleeve 22 through the screw guide 25. The spindle 21 applies work to the energy storage member 23 so that the energy storage member 23 stores energy. The guide pin 24 may be kept in contact with the screw guide 25. When the sleeve 22 is rotated to the second locking position, the rotation is stopped. At this time, the spindle 21 is located at the second position, and the first body 31 is located at the open position.

In some examples, the energy storage component 23 includes an elastic member. An elastic member may be provided at one end of the mandrel 21 in the axial direction X of the sleeve 22. Both the spindle 21 and the elastic element are located in the guide chute 100. The spindle 21 slides relative to the sleeve 22 to cause the spring to accumulate energy or release energy.

In some examples, the frame plate 321 may cover the guide chute 100 to cover the energy storage member 23, reducing the likelihood that the energy storage member 23 will be withdrawn from the guide chute 100 out of connection with the second body 32.

In some examples, the second body 32 is provided with a relief notch. The guide chute 100 communicates with the avoidance gap. The guide sliding grooves 100 are respectively arranged on two sides of the avoidance gap along the axial direction X of the sleeve 22.
