Referring to fig. 1 and 2, an electronic device 100 of the present embodiment includes a housing assembly 10 and a flexible display 20. The housing assembly 10 is hollow, and the flexible display 20 is disposed on the housing assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), both of which may be disposed on the housing assembly 10. The circuit board may integrate the processor, power management module, memory unit, baseband chip, etc. of the electronic device 100. The flexible display 20 is communicatively coupled to a circuit board, and the battery is capable of powering the flexible display 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module (not shown), where the camera module is communicatively connected to the circuit board, and the battery can supply power to the camera module. It is understood that the electronic device 100 according to the embodiment of the present application may be, but not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 100. In the embodiment of the present application, a mobile phone will be described as an example.

Referring to fig. 3, in an embodiment of the present application, the housing assembly 10 includes a first housing 12 and a second housing 14, the second housing 14 and the first housing 12 being capable of relative movement. Specifically, in the present embodiment, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 is capable of sliding relative to the first housing 12. For example, one of the first housing 12 and the second housing 14 may be provided with a slide rail along which the other can slide to cause movement of the end of the second housing 14 remote from the first housing 12 toward or away from each other with the end of the first housing 12 remote from the second housing 14.

Further, the second housing 14 is capable of sliding to a first position and a second position relative to the first housing 12. Referring to fig. 2, when the second housing 14 is in the first position, the housing assembly 10 and the electronic device 100 are in the unfolded state, and the electronic device 100 has a relatively large display area, so as to enhance the use experience of the electronic device 100; when the second housing 14 is in the second position, referring to fig. 1, the case assembly 10 and the electronic device 100 are in a collapsed state, and the electronic device 100 has a relatively small external dimension and is convenient to carry. It is to be understood that in the following embodiments of the present application, the first position, the second position, and the like refer to the relative positions of the second housing 14 and the first housing 12. For simplicity, the similar expressions "the second housing 14 is in the first position" or "when in the first position" refer to the second housing 14 being in the first position relative to the first housing 12, i.e., the electronic device 100 being in the unfolded state, and the similar expressions "the second housing 14 is in the second position" or "when in the second position" refer to the second housing 14 being in the second position relative to the first housing 12, i.e., the housing assembly 10 and the electronic device 100 being in the folded state.

It will be appreciated that in embodiments of the present application, the electronic device 100 may be considered to be in the deployed state when the housing assembly 10 is in the deployed state; the electronic device 100 may also be considered to be in a collapsed state when the housing assembly 10 is in a collapsed state.

Further, in the embodiment of the present application, when the end of the second housing 14 away from the first housing 12 and the end of the first housing 12 away from the second housing 14 are moved closer to each other, that is, during the switching of the electronic device 100 from the unfolded state to the folded state, the second housing 14 and the first housing 12 may be considered to move relatively closer to each other, and the movement direction of the second housing 14 may be directed from the first position to the second position, or from the end of the second housing 14 away from the first housing 12 to the first housing 12, for simplicity of description; when the end of the second housing 14 away from the first housing 12 and the end of the first housing 12 away from the second housing 14 move away from each other, that is, during the switching of the electronic device 100 from the folded state to the unfolded state, for simplicity of description, the second housing 14 and the first housing 12 may be considered to move relatively away from each other, and the movement direction of the second housing 14 may be directed from the second position to the first position, or may be directed from the end of the first housing 12 away from the second housing 14 to the second housing 14.

In the present embodiment, the position of the end of the second housing 14 away from the first housing 12, and the end of the first housing 12 away from the second housing 14 can be more clearly determined with reference to the first position. Taking fig. 2 as an example, when the second housing 14 is at the first position, the leftmost side of the electronic device 100 in the width direction is the end of the second housing 14 away from the first housing 12, and the rightmost side of the electronic device 100 in the width direction is the end of the first housing 12 away from the second housing 14.

In the present embodiment, when the second housing 14 is in the first position, the overall width of the electronic device 100 is greater than that in the second position, so that the width dimension of the exposed flexible display 20 is variable. In other words, the electronic apparatus 100 is variable in size in the width direction. In other embodiments, the overall length of the electronic device 100 is greater than the length in the second position when the second housing 14 is in the first position, such that the length dimension of the exposed flexible display 20 is variable. In other words, the electronic device 100 is variable in size in the longitudinal direction.

Referring to fig. 1 and 2, the flexible display 20 may include a fixed portion 20a and a free portion 20b disposed opposite to each other, where the fixed portion 20a is disposed on the first housing 12 and is fixed relative to the first housing 12. In the second position, the flexible display 20 bypasses an end of the second housing 14 away from the first housing 12, and the free portion 20b of the flexible display 20 is received in the housing assembly 10, such that a portion of the flexible display 20 is hidden in the housing assembly 10, and a portion of the flexible display 20 hidden in the housing assembly 10 may not be used for display. In other words, movement of the first housing 12 relative to the second housing 14 may cause at least a portion of the free portion 20b to be deployed within the second housing 14, or the free portion 20b deployed within the second housing 14 to be retracted within the housing assembly 10. That is, the flexible display 20 may be moved into and out of the housing assembly 10 during the switching of the housing assembly 10 between the expanded state and the collapsed state.

It will be appreciated that in embodiments of the present application, the relative positions of the two objects are fixed, i.e. the two objects cannot normally generate relative movement or the relative movement between the two objects is negligible, and the two objects with the relative positions being fixed may be physically connected directly, or may be indirectly connected through an intermediate structure. For example, the fixing portion 20a and the first housing 12 are fixed relatively, and the fixing portion 20a and the first housing 12 may be in direct contact with each other, for example, by using a threaded fastener or a clamping method, or the fixing portion 20a may be indirectly fixed to the first housing 12 by using an adhesive layer, an intermediate connection plate, or the like, for example, for the fixing portion 20a and the first housing 12.

It is understood that the fixed portion 20a and the free portion 20b can be distinguished in the following manner, when the second housing 14 is in the second position relative to the first housing 12, that is, the electronic device 100 is in the folded state, the portion of the flexible display 20 exposed outside the housing assembly 10 is the fixed portion 20a of the flexible display 20, and the portion of the flexible display 20 accommodated in the housing assembly 10 can be regarded as the free portion 20b. In some embodiments, when the second housing 14 is in the second position, i.e. the electronic device 100 is in the folded state, the fixing portion 20a exposed outside the housing assembly 10 is generally rectangular, and its size may be 5-6 inches, i.e. the size is equivalent to that of the display screen of a typical smart phone, so that the electronic device 100 is convenient to carry and use.

Referring to fig. 3, the electronic device 100 may include a guide 30, where the guide 30 is disposed at an end of the second housing 14 away from the first housing 12, and the guide 30 may guide the flexible display 20 to deform and expand in the second housing 14 during the second housing 14 is switched from the second position to the first position relative to the first housing 12. The guide 30 may limit the bending radius of the flexible display 20 to a suitable range to avoid damage to the flexible display 20 caused by too small a bending radius. Of course, the guide 30 may also avoid the excessive thickness of the electronic device 100 caused by the excessive bending radius of the flexible display 20.

In some embodiments, the guide 30 may be a rotating shaft structure with protruding teeth, and the flexible display 20 is coupled to the guide 30 by engagement or the like. When the second housing 14 slides relative to the first housing 12, the guide 30 moves the portion of the flexible display 20 engaged with the guide 30 and expands or retracts the housing assembly 10.

It will be appreciated that in other embodiments, the guide 30 may also be a circular shaft without teeth attached. During the switching of the second housing 14 from the second position to the first position, the portion of the flexible display 20 attached to the guide 30 is spread by the guide 30 so that more of the flexible display 20 is exposed to the outside of the case assembly 10 and is in a flat state. In this embodiment, the guide 30 may be rotatably disposed on the second housing 14, and the guide 30 may be rotated along with the movement of the flexible display 20 during the gradual deployment of the flexible display 20, so as to reduce the resistance of the flexible display 20 during the deployment and reduce the abrasion of the contact portion of the guide 30 and the flexible display 20.

In other embodiments, the guide 30 may also be fixed to the second housing 14, with the guide 30 having a smooth surface. The guide 30 is slidably contacted with the flexible display 20 through a smooth surface thereof during the process of expanding the flexible display 20 to the second housing 14. In other words, in such an embodiment, the guide 30 may be integrally formed, assembled, or welded with the second housing 14.

During the switching of the second housing 14 from the first position to the second position, the flexible display 20 may be retracted by the guide 30, i.e. the portion of the flexible display 20 deployed in the second housing 14 is retracted within the housing assembly 10.

Further, referring to fig. 4, the electronic device 100 may include a driving mechanism 40, where the driving mechanism 40 may be disposed in the housing assembly 10, and the driving mechanism 40 may be coupled with the first housing 12 or the second housing 14 to drive the second housing 14 to move relative to the first housing 12, so as to drive the flexible display 20 to be extended or retracted. In some embodiments, the drive mechanism 40 employs a threaded transmission mechanism that includes a motor, a screw, and a nut. In other embodiments, the driving mechanism 40 may be a gear mechanism such as a rack and pinion.

It will be appreciated that in this embodiment, the first and second positions may be considered as two extreme positions of movement of the second housing 14 relative to the first housing 12. In the first position, the display area of the flexible display 20 reaches a maximum, and the second housing 14 is no longer able to move relatively far away from the first housing 12 under normal conditions. In the second position, the display area of the flexible display 20 is minimized and the second housing 14 is normally no longer capable of relatively close movement relative to the first housing 12. The first and second positions may be achieved by providing a locking structure on the housing assembly 10 or the guide 30.

It can be appreciated that a plurality of intermediate positions may be further disposed between the first position and the second position, so as to position the second housing 14 relative to the first housing 12 at the plurality of intermediate positions, and enable the flexible display 20 to have different display areas at different intermediate positions, thereby expanding the usage scenario of the electronic device 100. The plurality of intermediate position liquids may be implemented using other locking structures.

Referring to fig. 4 and 5, in the present embodiment, the electronic device 100 includes a locking mechanism 50, and the locking mechanism 50 is used for locking the electronic device 100 in the first position, that is, the unfolded state, so that the second housing 14 can be locked in the first position after being moved to the first position, to maintain the unfolded state of the case assembly 10. After the housing assembly 10 in the unfolded state is locked by the locking mechanism 50, the housing assembly 10 can be regarded as a whole, and after the electronic device 100 is impacted, for example, accidentally dropped, the housing assembly 10 in the unfolded state can be used for absorbing the impact, so as to avoid the abnormal relative movement of relevant moving parts of the driving mechanism 40 caused by the fact that the second housing 14 easily slides to the second position relative to the first housing 12, thereby protecting the moving parts and improving the shock resistance of the electronic device 100.

Specifically, referring to fig. 6 and 7, the locking mechanism 50 includes a locking member 51 and a locking assembly 53, the locking member 51 is connected to the second housing 14, the locking assembly 53 is disposed on the first housing 12, and during the sliding process of the second housing 14 relative to the first housing 12, the second housing 14 drives the locking member 51 to move relative to the first housing 12, so that the locking member 51 and the locking assembly 53 can approach each other or separate from each other. During the process of switching the shell assembly 10 from the folded state to the unfolded state, when the second shell 14 moves relative to the first shell 12 and approaches to the first position, the locking member 51 may contact the locking assembly 53 and drive the locking assembly 53 to move so as to achieve the locking of the locking member 51 and the locking assembly 53, and enable the shell assembly 10 to be kept in the unfolded state.

In some embodiments, as shown in fig. 4, locking mechanism 50 is disposed in more than two spaced apart relation in a direction perpendicular to the sliding of second housing 14 relative to first housing 12. The locking of the housing assembly 10 by the more than two locking mechanisms 50 ensures the reliability of the locking of the housing assembly 10 when the second housing 14 slides relative to the first housing 12 to the first position, preventing the second housing 14 from easily sliding relative to the first housing 12 to the second position and causing abnormal relative movement of the associated moving parts of the drive mechanism 40.

Referring to fig. 7 and 8, the locking assembly 53 includes a supporting member 531 and a movable member 533, the movable member 533 is movably disposed on the supporting member 531, and the engaging member 51 is provided with a slot 51a. During the process of switching the housing assembly 10 from the folded state to the unfolded state, the engaging member 51 is used for driving the movable member 533 to move relative to the supporting member 531 so as to be away from the engaging member 51 in the circumferential direction of the engaging member 51. The movable member 533 is further configured to be driven to move relative to the supporting member 531 to approach the engaging member 51 in the circumferential direction of the engaging member 51 and enter the engaging groove 51a, so that the movable member 533 engages with the engaging member 51.

In the embodiment of the present application, the supporting member 531 and the engaging member 51 are substantially cylindrical, the extending direction of the length of the engaging member 51 and the sliding direction of the second housing 14 relative to the first housing 12 may be parallel, the engaging groove 51a is disposed around the circumference of the engaging member 51, and the engaging groove 51a may be an arc-shaped groove.

In one embodiment, the movable member 533 is a ball and is rotatably disposed on the supporting member 531. The supporting member 531 may be provided with more than two mounting holes 531a spaced apart along the circumferential direction, and each mounting hole 531a is correspondingly provided with a movable member 533. In one embodiment, the support 531 is uniformly provided with 3 mounting holes 531a at intervals along the circumferential direction. Because the movable member 533 is a ball and is rotatably disposed on the supporting member 531, the movable member 533 can roll relative to the supporting member 531 and the engaging member 51 during the process of the engaging member 51 moving into and out of the supporting member 531, so as to reduce the movement resistance between the movable member 533 and the supporting member 531, and avoid the difficulty in the engaging member 51 extending into or exiting from the supporting member 531 due to the self-locking of the movable member 533 and the supporting member 531. Of course, in other embodiments, the movable member 533 may have a cylindrical shape, and both ends thereof may be machined into a hemispherical shape, so that the movable member 533 can move in a telescopic manner relative to the support member 531 during the process of extending into or retracting out of the support member 531, so as to achieve engagement and unlocking with the engagement member 51.

During the process of relatively moving the second housing 14 away from the first housing 12, that is, during the process of switching the housing assembly 10 from the folded state to the unfolded state, when the second housing 14 slides to the first position relative to the first housing 12, the clamping member 51 presses the movable member 533, and pushes the movable member 533 away from the clamping member 51 in the radial direction of the clamping member 51, so that the clamping member 51 can gradually extend into the supporting member 531; when the clamping groove 51a of the clamping piece 51 moves to the position of the movable piece 533, the movable piece 533 can be driven to approach the clamping piece 51 along the radial direction of the clamping piece 51 and enter the clamping groove 51 a; when the movable member 533 enters the locking groove 51a and is limited in the locking groove 51a, as shown in fig. 9, the movable member 533 can limit the movement of the locking member 51 in the direction of the second housing 14 relative to the first housing 12, so as to lock the second housing 14 in the first position, i.e. keep the electronic device 100 in the unfolded state.

It is understood that, in the embodiment where the movable member 533 is a ball, the minimum width of the mounting hole 531a may be smaller than the diameter of the ball, so that the hole wall of the mounting hole 531a is used to support the movable member 533 after the engaging member 51 is withdrawn from the supporting member 531, so as to prevent the ball from falling into the supporting member 531 after the engaging member 51 is withdrawn from the supporting member 531.

With continued reference to fig. 8, in some embodiments, the locking assembly 53 includes a reset element 535, where the reset element 535 abuts against the first housing 12 and the supporting element 531, and in the process of switching the housing assembly 10 from the folded state to the unfolded state, the engaging element 51 is used to push the supporting element 531 to move along the direction of the second housing 14 away from the first housing 12 (i.e. the direction of the second position pointing to the first position) so as to compress the reset element 535, and drive the movable element 533 to move away from the engaging element 51 in the circumferential direction of the engaging element 51. The restoring member 535 in the compressed state is used for pushing the supporting member 531 to move along the direction of the second housing 14 approaching the first housing 12 (i.e. the direction of the first position pointing to the second position), so as to drive the movable member 533 to approach the engaging member 51 in the circumferential direction of the engaging member 51 and enter the clamping groove 51a. In some embodiments, the return 535 is a spring. In other embodiments, the restoring member 535 may be a resilient post or a spring, etc.

Further, in the present embodiment, referring to fig. 7 and 9, the support 531 includes a frustum 5311 and a connection portion 5313 connected to the frustum 5311, and the width of the cross section of the frustum 5311 gradually decreases from one end of the frustum 5311 near the connection portion 5313 to one end distant from the connection portion 5313. The outer contour of the cross section of the frustum 5311 may be circular, i.e., the frustum 5311 may be a truncated cone. The cross section of the frustum 5311 may have an outer contour of an ellipse, a quadrangle, a pentagon, or the like.

The movable member 533 is disposed on the frustum 5311, and one end of the restoring member 535 is disposed on the connecting portion 5313. Referring to fig. 8, the first housing 12 is provided with a mounting boss 121, and the mounting boss 121 may be a part of the first housing 12. The opposite end of the reset member 535 abuts against the mounting boss 121, and the connecting portion 5313 is spaced from the mounting boss 121 when the housing assembly 10 is in the folded state. In other words, in the collapsed state of the case assembly 10, there is a space between the mounting boss 121 and one end of the support 531 adjacent to the mounting boss 121.

With continued reference to fig. 7 and 9, in some embodiments, the frustum 5311 is provided with a first through hole 5311a in communication with the mounting hole 531a, and the engaging member 51 is configured to enter the supporting member 531 from the first through hole 5311 a. The connection portion 5313 has a second through hole 5313a communicating with the first through hole 5311a, and the reset element 535 is disposed through the second through hole 5313a. When the housing assembly 10 is in the folded state, the movable member 533 may protrude from the wall of the first through hole 5311 a. When the shell assembly 10 is switched from the folded state to the unfolded state and the engaging member 51 extends into the first through hole 5311a, the portion of the movable member 533 protruding out of the hole wall of the first through hole 5311a can be mutually pressed against the engaging member 51, so that the movable member 533 is pushed by the engaging member 51 to be far away from the engaging member 51 along the circumferential direction of the engaging member 51 in the mounting hole 531a, and the supporting member 531 is pushed by the acting force of the movable member 533 to the supporting member 531 to move towards the mounting boss 121 to compress the reset member 535.

The locking assembly 53 may further include a sleeve 537 connected to the mounting boss 121, the sleeve 537 being sleeved on the support 531, and an end of the sleeve 537 remote from the mounting boss 121 being matched with the shape of the frustum 5311. For example, in embodiments where the frustum 5311 is a truncated cone, the inner contour of the cross-section of the end of the sleeve 537 remote from the mounting boss 121 is circular. When the shell assembly 10 is in the folded state, the supporting member 531 can be abutted against the end of the sleeve 537 away from the mounting boss 121 under the action of the elastic force of the reset member 535. At this time, when the support 531 and the sleeve 537 are cut out with the same geometric plane at which the diameter of the inner contour of the sleeve 537 is slightly larger than the diameter of the outer contour of the frustum 5311 and two cross sections are obtained. That is, the circumferential direction of the frustum 5311 is spaced from the sleeve 537 when the housing assembly 10 is in the collapsed state.

During the process of switching the case assembly 10 from the folded state to the unfolded state, the engaging member 51 extends into the first through hole 5311a of the supporting member 531 when the second case 14 slides to be close to the first position relative to the first case 12. Taking the movable member 533 as an example, the radial distance between the position of the engaging member 51, which is in contact with the movable member 533, and the inner wall of the sleeve 537 is only required to be ensured to be smaller than the diameter of the movable member 533, and the engaging member 51 and the movable member 533 can be mutually extruded, so that the movable member 533 generates a movement trend away from the engaging member 51 along the circumferential direction of the engaging member 51; when the engaging member 51 pushes the supporting member 531 to move toward the mounting boss 121 by the movable member 533 to compress the restoring member 535, the movable member 533 can be away from the engaging member 51 along the circumferential direction of the engaging member 51. In this process, the force of the restoring member 535 against the supporting member 531 causes the supporting member 531 to have a moving tendency away from the mounting boss 121. Of course, in this process, there may be a friction force between the engaging member 51 and the wall of the first through hole 5311a to push the support 531 to move toward the mounting boss 121 by the friction force. It should be understood that the diameter of the balls is also sufficient that when the support member 531 moves toward the mounting boss 121 to abut against the mounting boss 121, the balls do not interfere with the movement of the engaging member 51, so as to ensure that the engaging member 51 can smoothly extend into the support member 531.

When the engaging member 51 extends into the sleeve 537 for a certain distance, so that the diameter of the engaging member 51 at the engaging member 51a is reduced when the engaging groove 51a of the engaging member 51 moves to the position where the ball is located, and the contact between the engaging member 51 and the movable member 533 is insufficient to overcome the elastic force of the restoring member 535 on the supporting member 531, the supporting member 531 can move away from the mounting boss 121 under the action of the restoring member 535. In this process, the inner wall of the sleeve 537 may press the movable member 533 so that the movable member 533 approaches the engaging member 51 in the circumferential direction of the engaging member 51 and is engaged into the engaging groove 51a. The restoring member 535 applies a force to the supporting member 531, so that the inner wall of the sleeve 537 and the engaging member 51 respectively press the movable member 533 in the radial direction of the engaging member 51, and the engaging member 51 is difficult to move toward the mounting boss 121 and to withdraw from the locking member 53, so that the second housing 14 can no longer move relative to the first housing 12 under normal conditions to maintain the unfolded state of the housing assembly 10.

In the electronic device 100, since the locking mechanism 50 includes the engaging member 51 and the locking assembly 53, the engaging member 51 and the locking assembly 53 are respectively connected to the shell assembly 10, and in the process of switching the shell assembly 10 from the folded state to the unfolded state, the engaging member 51 is used for driving the locking assembly 53 to move so as to engage the engaging member 51 with the locking assembly 53, so that the shell assembly 10 is kept in the unfolded state, and when the electronic device 100 equipped with the locking mechanism 50 is impacted, for example, falls accidentally, the electronic device 100 can be kept in the unfolded state by the engaging member 51 and the locking assembly 53, so that the shell assembly 10 in the unfolded state absorbs the impact force, and the shell assembly 10 is prevented from being abnormally switched to the folded state due to the impact, and further, the related moving parts are prevented from being damaged due to large relative movement, thereby improving the impact resistance of the electronic device 100.

With continued reference to fig. 7 and 8, the locking mechanism 50 may further include an unlocking component 55 connected to the first housing 12, where the unlocking component 55 is configured to drive the support member 531 to move along a direction of the second housing 14 away from the first housing 12 (i.e. the second position points to the first position), and the relative movement of the support member 531 and the engaging member 51 may enable the movable member 533 to be far away from the engaging member 51 in a circumferential direction of the engaging member 51, so that the movable member 533 is retracted out of the slot 51a, and further, the locking effect of the engaging member 51 and the locking component 53 is released, so that the second housing 14 can move towards the second position with respect to the first housing 12 again.

In some embodiments, the unlocking assembly 55 includes a coil 551 and an electromagnet 553, the coil 551 is wound around the outer circumference of the support 531 and fixedly connected with the support 531, and the electromagnet 553 is connected to the first housing 12. For example, in the present embodiment, the sleeve 537 is crimped to one side of the mounting boss 121, and the lock assembly 53 is restrained to one side of the mounting boss 121. The coil 551 is sleeved on the connection portion 5313 and may be disposed near the mounting boss 121, for example, the connection portion 5313 and the frustum 5311 of the support 531 may form a recessed region 531b in a circumferential direction of an end of the support 531 near the electromagnet 553, and the coil 551 is disposed in the recessed region 531b to achieve reliable limiting of the coil 551 on the support 531 and reduce a radial dimension of the locking assembly 53 at the coil 551. The electromagnet 553 is disposed on the opposite side of the mounting boss 121.

When both the coil 551 and the electromagnet 553 are energized, a magnetic attraction is generated between the coil 551 and the electromagnet 553. For example, in some embodiments, when both the coil 551 and the electromagnet 553 are energized, a side of the coil 551 near the mounting boss 121 is S-pole, and a side of the electromagnet 553 near the coil 551 is N-pole, so that a magnetic attraction force can be generated between the coil 551 and the electromagnet 553 to drive the support 531 to move toward the mounting boss 121, and the movable piece 533 is withdrawn from the clamping groove 51a of the clamping piece 51.

Of course, in other embodiments, when both the coil 551 and the electromagnet 553 are energized, the side of the coil 551 close to the mounting boss 121 is N-pole, and the side of the electromagnet 553 close to the coil 551 is S-pole, and this arrangement can also generate a magnetic attraction between the coil 551 and the electromagnet 553, so as to drive the support 531 to move toward the mounting boss 121, and enable the movable element 533 to withdraw from the clamping slot 51a of the clamping element 51.

It is understood that the support member 531 may be fixed relative to the first housing 12, that is, the support member 531 and the first housing 12 do not generate relative movement during the process that the engaging member 51 pushes the movable member 533 away from the support member 531 along the circumferential direction of the engaging member 51. In such an embodiment, the reset member 535 is not required. For example, the locking mechanism 50 may include an elastic member connected to the movable member 533 to urge the movable member 533 away from the engaging member 51 in the circumferential direction of the engaging member 51 and compress the elastic member during the process of the engaging member 51 extending into the supporting member 531; when the clamping groove 51a of the clamping member 51 moves to the position of the movable member 533, the elastic member drives the movable member 533 to approach the clamping member 51 along the circumferential direction of the clamping member 51 and enter the clamping groove 51a, so as to achieve the clamping between the clamping member 51 and the movable member 533.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
