Referring to fig. 1, 2 and 3, an electronic device 100 of the present embodiment includes a case assembly 10, a flexible display 20 and a guide 30. The case assembly 10 has a hollow structure, and the flexible display 20, the guide 30, and the like may be provided in the case assembly 10. The electronic device 100 may further include a circuit board (not shown) and a battery (not shown), and both the circuit board and the battery may be disposed on the housing assembly 10. The circuit board may integrate a processor, a power management module, a memory unit, a baseband chip, and the like of the electronic device 100. The flexible display screen 20 is in communication with the circuit board, and the battery can supply power to the flexible display screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may further include a camera module 40, the camera module 40 is connected to the circuit board in communication, and the battery can supply power to the camera module 40. It is understood that the electronic device 100 according to the embodiment of the present disclosure may be, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 100. In the embodiments of the present application, a mobile phone is taken as an example for description.

Referring to fig. 3, 4 and 5, in the present embodiment, the shell assembly 10 includes a first shell 12 and a second shell 14, and the second shell 14 and the first shell 12 are 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 slidable 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, and the other may slide along the slide rail, so that the end of the second housing 14 far from the first housing 12 and the end of the first housing 12 far from the second housing 14 move toward or away from each other.

Further, the second housing 14 is slidable relative to the first housing 12 to a first position and a second position. With reference to fig. 4, when the second housing 14 is in the first position, the electronic device 100 can obtain 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 (refer to fig. 1), the electronic device 100 has a relatively small external size and is convenient to carry. It is understood that in the embodiments hereinafter described in 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, similar expressions that refer to the second housing 14 being in a first position relative to the first housing 12, and that refer to the second housing 14 being in a second position relative to the first housing 12, and that refer to the second housing 14 being in a first position relative to the first housing 12.

In the present embodiment, with the first position as a reference, the positions of the end of the second casing 14 away from the first casing 12 and the end of the first casing 12 away from the second casing 14 can be determined more clearly. Taking fig. 4 as an example, when the second casing 14 is at the first position, the leftmost side of the electronic device 100 in the width direction is the end of the second casing 14 away from the first casing 12, and the rightmost side of the electronic device 100 in the width direction is the end of the first casing 12 away from the second casing 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 the width in the second position, so that the width dimension of the exposed flexible display 20 is variable. In other words, the electronic apparatus 100 may vary in size in the width direction. In such an embodiment, an interface of the electronic device 100, such as a data line jack or a charging line jack or a headphone jack, may be provided at the end in the width direction. In other embodiments, when the second housing 14 is in the first position, the overall length of the electronic device 100 is greater than the length in the second position, so that the length dimension of the exposed flexible display 20 is variable. In other words, the electronic apparatus 100 may vary in size in the longitudinal direction. In such an embodiment, an interface of the electronic device 100, such as a data line jack or a charging line jack or a headphone jack, may be provided at an end of the length direction.

Referring to fig. 6, the flexible display 20 may include a fixed portion 20a and a free portion 20b, which are disposed opposite to each other, and the fixed portion 20a is disposed on the first casing 12 and fixed relative to the first casing 12. In the second position, flexible display 20 bypasses guide 30 and free portion 20b of flexible display 20 is received within housing assembly 10 such that a portion of flexible display 20 is hidden from housing assembly 10 and a portion of flexible display 20 hidden from 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 deploy from the second housing 14, or cause the free portion 20b deployed from the second housing 14 to retract into the housing assembly 10.

It is understood that in the embodiments of the present application, the two objects are fixed relative to each other, that is, the two objects cannot move relative to each other under normal conditions or the relative movement between the two objects is negligible, and the two objects fixed relative to each other may be directly connected physically or indirectly connected through an intermediate structure. Taking the fixing portion 20a and the first housing 12 as an example, the position of the fixing portion 20a and the first housing 12 are relatively fixed, the fixing portion 20a may directly contact with the first housing 12, for example, the fixing portion 20a and the first housing 12 are directly fixed by using a threaded fastener or a clamping manner, or the fixing portion 20a and the first housing 12 may be indirectly fixed by using an adhesive layer, an intermediate connecting plate, or other structures.

It is understood that the fixed portion 20a and the free portion 20b can be distinguished in such a way that when the second housing 14 is located at the second position relative to the first housing 12, 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 is the free portion 20 b. In some embodiments, when the second housing 14 is located at the second position, the fixing portion 20a exposed outside the housing assembly 10 is substantially rectangular, and the size thereof may be 5-6 inches, that is, the size of the display screen of a general smart phone, so that the electronic device 100 is convenient to carry and use.

Further, referring to fig. 5, the second housing 14 may include a rear cover 142, the rear cover 142 covering the free portion 20b of the flexible display 20 when in the second position. The rear cover 142 may be provided with a light-transmitting area, and the portion of the flexible display 20 accommodated in the housing assembly 10 in the second position may also be used for displaying, so that a user can view information displayed by the flexible display 20 from the light-transmitting area, thereby expanding a use scene of the electronic device 100. For example, in this embodiment, the electronic device 100 can implement functions such as self-shooting, video call, etc. by using the rear camera module 40 without providing a front camera. The light-transmitting area may be made of transparent glass or may be formed by an opening of the rear cover 142. After the second housing 14 is slid to a first position relative to the first housing 12, at least a portion of the flexible display screen 20 housed in the housing assembly 10 is exposed. The exposed flexible display screen 20 can be used for displaying, so that the electronic device 100 has a relatively large display area to enhance the use experience of the user.

With reference to fig. 6, in the present embodiment, the guiding element 30 is disposed at an end of the second casing 14 away from the first casing 12, and the guiding element 30 can guide the flexible display 20 to deform and unfold on the second casing 14 during the process of switching the second casing 14 from the second position to the first position relative to the first casing 12. The guide 30 may limit the bending radius of the flexible display 20 within a suitable range to avoid damage to the flexible display 20 due to an excessively small bending radius. Of course, the guide 30 can also avoid the thickness of the electronic device 100 from being too large due to too large bending radius of the flexible display 20.

In some embodiments, the guide 30 may be a shaft structure with convex teeth, and the flexible display 20 is coupled with the guide 30 by engaging or the like. When the second housing 14 slides relative to the first housing 12, the portion of the flexible display screen 20 engaged with the guide member 30 is moved by the guide member 30 and is deployed or retracted into the case assembly 10.

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

Referring to fig. 6 and 7, in the present embodiment, the guide 30 has a circular shaft shape. The electronic device 100 may further include a pulley 51 and a pull belt 53, the guide member 30 is rotatably coupled to an end of the second housing 14 away from the first housing 12, and the pulley 51 is rotatably coupled to an end of the second housing 14 away from the guide member 30. The pull belt 53 has one end connected to the free portion 20b and the other end wound around the pulley 51 and connected to the first housing 12. In this embodiment, reference may be made to the first housing 12, i.e., the position of the first housing 12 is considered to be fixed, and the guide 30 and the pulley 51 function as a movable pulley, respectively. When the second housing 14 moves relative to the first housing 12 by a distance d, the sliding length of the free portion 20b relative to the guide 30 and the sliding length of the traction belt 53 relative to the pulley 51 are both 2 d. Therefore, the cooperation of the guide 30, the pulley 51 and the traction belt 53 can tension the free portion 20b, i.e. a proper tension force is generated in the free portion 20b by the abutting action of the guide 30 on the free portion 20b and the abutting action of the pulley 51 on the traction belt 53, so as to prevent the flexible display screen 20 from being wrinkled or jammed during the process of extending or retracting the housing assembly 10, thereby ensuring the smooth extension and retraction of the flexible display screen 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 in slidable contact with the flexible display 20 through its smooth surface during the process of unfolding the flexible display 20 into the second housing 14. In other words, in this embodiment, the guide member 30 may be integrally formed with the second housing 14 or welded, the guide member 30 may be regarded as a part of the second housing 14, and the free portion 20b of the flexible display screen 20 bypasses an end of the second housing 14 far from the first housing 12 and protrudes into the case assembly 10.

During the process of switching the second housing 14 from the first position to the second position, the flexible display 20 can be retracted by the guide 30, i.e. the portion of the flexible display 20 that is deployed in the second housing 14 is retracted into the case assembly 10. Further, referring to fig. 8, the electronic device 100 may include a driving mechanism 60, the driving mechanism 60 may be disposed in the housing assembly 10, and the driving mechanism 60 may be linked 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 extend or retract. It will be appreciated that the drive mechanism 60 may be omitted and the user may directly, manually or the like, move the second housing 14 and the first housing 12 relative to one another.

It is understood that, in the present embodiment, the first position and the second position can be regarded as two extreme positions of the 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 under normal conditions, the second housing 14 can no longer move relatively far away from the first housing 12. In the second position, the display area of the flexible display 20 is minimized, and the second housing 14 can no longer move closer to the first housing 12 under normal conditions. The first and second positions may be achieved by providing a stop structure 70 on the second housing 14 or the first housing 12 or the guide 30.

For example, the stop structure 70 may be connected to the first housing 12. In the first position, the second housing 14 abuts against the limiting structure 70, so as to limit the moving range of the second housing 14 in the first housing 12, and limit the second housing 14 at the first position. Further, the end of the slide rail for sliding the first housing 12 and the second housing 14 can be used as the limiting structure 70. Of course, it is understood that the limiting structure 70 need not be made as a separate component, but can be integrally formed with the first housing 12 to simplify the structure of the electronic device 100. In other embodiments, the limiting structure 70 may be connected to the second housing 14, and the first housing 12 may abut against the limiting structure 70 in the first position, which may also reliably limit the second housing 14 in the first position.

It is understood that a plurality of intermediate positions may be further disposed between the first position and the second position to achieve the positioning of the second housing 14 relative to the first housing 12 at the plurality of intermediate positions, and to enable the flexible display 20 to have different display areas at different intermediate positions, thereby expanding the use scene of the electronic device 100. The intermediate positions may be achieved using other stop structures 70, such as spring tabs.

Referring to fig. 9, in the present embodiment, the electronic device 100 includes a telescopic element 80, and the telescopic element 80 is slidably disposed in one of the first housing 12 and the second housing 14. After the second housing 14 slides relative to the first housing 12 and brings the free portion 20b into and out of the shell assembly 10, the telescopic member 80 can be driven to slide to the other of the first housing 12 and the second housing 14, so that the positions of the first housing 12 and the second housing 14 are relatively fixed. In other words, the telescopic member 80 can realize the mutual locking of the first casing 12 and the second casing 14, so that the two casings are approximately integrated. When the first housing 12 or the second housing 14 is subjected to an unexpected impact such as a collision, the second housing 14 cannot easily slide relative to the first housing 12, and the impact can be absorbed by the first housing 12 and the second housing 14 together, so as to prevent the driving mechanism 60 and other relevant moving parts from being damaged, thereby improving the impact resistance of the electronic device 100.

The present application will be described taking as an example the extensible member 80 provided in the first housing 12. It is understood that in other embodiments, the telescoping member 80 may be provided to the second housing 14.

Further, referring to fig. 9 and 10, in the present embodiment, the telescopic member 80 is substantially rod-shaped, and the second housing 14 is opened with a slot 14a, where the slot 14a is used for cooperating with the telescopic member 80 to fix the positions of the first housing 12 and the second housing 14 relatively.

Specifically, in the first position, the retractable member 80 may extend into the slot 14a and cooperate with the slot 14a to limit the movement of the second housing 14 to the second position. In other words, when the flexible display screen 20 is unfolded to be in the large screen display state, the mutual cooperation between the telescopic member 80 and the slot 14a can achieve relative fixing of the positions of the first housing 12 and the second housing 14, so as to prevent the second housing 14 or the first housing 12 from easily moving to the second position when the second housing 14 or the first housing 12 is impacted, for example, accidentally dropped. That is, in the case where the telescopic member 80 is engaged with the engaging groove 14a, the first housing 12 and the second housing 14 can be simply regarded as a whole, so that the impact force can be absorbed by both the first housing 12 and the second housing 14 to prevent the impact force from damaging the moving parts and other moving parts of the driving mechanism 60.

Referring to fig. 11 and 12, the electronic apparatus 100 includes a guide member 90 coupled to the first housing 12, and the telescopic member 80 is slidably fitted to the guide member 90. In this embodiment, the guide member 90 is generally rectangular block-shaped and may be removably attached to the first housing 12 using threaded fasteners. Of course, the guide 90 may be fixedly connected to the first housing 12 by welding, bonding, riveting, or the like.

Further, in the present embodiment, the guide member 90 is provided with a slide hole 90a, and the extensible member 80 is inserted into the slide hole 90a and can reciprocate along the slide hole 90a so as to extend into the card slot 14a of the second housing 14 or to withdraw from the card slot 14 a. Further, in the moving direction perpendicular to the second housing 14 relative to the first housing 12, the two opposite ends of the guiding element 90 are provided with two sliding holes 90a, that is, the two sliding holes 90a are spaced apart from each other, and the two sliding holes 90a are used for penetrating the telescopic element 80.

Telescoping member 80 may include a first pusher member 81, a connector 83, and a second pusher member 85, connector 83 being connected between first pusher member 81 and second pusher member 85, second pusher member 85 being configured to extend into card slot 14a and mate with card slot 14 a. After the first pushing member 81, the connecting member 83 and the second pushing member 85 are assembled, the axes thereof can be regarded as being located on the same straight line under the condition of considering engineering errors, and the first pushing member 81, the connecting member 83 and the second pushing member 85 can be regarded as a whole after being assembled, and the positions of the first pushing member 81, the connecting member 83 and the second pushing member 85 are relatively fixed. The first pushing member 81 is inserted into one of the sliding holes 90a and is in sliding fit with the guide 90 through the sliding hole 90a, and the second pushing member 85 is inserted into the other sliding hole 90a and is in sliding fit with the guide 90 through the sliding hole 90 a. The guiding element 90 may be provided with a notch 90b between the two sliding holes 90a, the notch 90b being communicated with the sliding holes 90a, and the connecting element 83 is accommodated in the notch 90b and can move synchronously with the first pushing element 81 and the second pushing element 85. Both ends of the notch 90b of the guide 90 can limit the moving range of the connecting member 83 to prevent the connecting member 83 from coming out of the notch 90 b.

In the present embodiment, an external thread is provided on one end of the first pusher 81 close to the second pusher 85, an external thread is similarly provided on one end of the second pusher 85 close to the first pusher 81, and the connector 83 is internally threaded and can be screwed with the first pusher 81 and the second pusher 85, respectively. In the process of assembling the first pushing member 81, the connecting member 83, the second pushing member 85 and the guide member 90, the connecting member 83 may be first placed in the notch 90b of the guide member 90, the first pushing member 81 may be inserted into the sliding hole 90a at one end of the guide member 90 to screw-connect the first pushing member 81 and the connecting member 83, and the second pushing member 85 may be inserted into the sliding hole 90a at the opposite end of the guide member 90 to screw-connect the second pushing member 85 and the connecting member 83.

Further, with continued reference to fig. 11 and 12, the electronic device 100 includes a reset member 87, wherein the reset member 87 is connected to one of the first pushing member 81 and the second pushing member 85 and the guiding member 90, so as to drive the telescopic member 80 out of the slot 14 a. Specifically, in the present embodiment, the reset element 87 includes a first elastic element 871 and a second elastic element 873, the first elastic element 871 is sleeved on the first pushing element 81, two ends of the first elastic element 871 respectively abut against one end of the guiding element 90 and the first pushing element 81, the second elastic element 873 is sleeved on the second pushing element 85, and two ends of the second elastic element 873 respectively abut against the opposite end of the guiding element 90 and the second pushing element 85. The reset member 87 is used to perform a reset movement of the telescopic member 80, so that the telescopic member 80 can be pulled out of the slot 14a of the second housing 14, thereby releasing the mutual locking of the first housing 12 and the second housing 14, so that the second housing 14 can move back to the second position relative to the first housing 12.

The reset movement may be simply understood as the movement of the telescopic member 80 to return to the initial position. For example, in the present embodiment, the extensible member 80 may be considered to be in the initial position when in the second position; the retractable member 80 can be actuated to move to another position relative to the first housing 12, and the restoring member 87 can be used to actuate the retractable member 80 to return to the original position again.

In this embodiment, the first elastic member 871 and the second elastic member 873 are both springs, and the structural parameters (elastic modulus, natural length) thereof may be the same, and the first elastic member 871 and the second elastic member 873 may be symmetrically distributed about the connection member 83. When the expansion piece 80 is not pressed and extends into the slot 14a, the compression amounts of the first elastic piece 871 and the second elastic piece 873 are approximately equal, the first pushing piece 81 and the second pushing piece 85 are in a stress balance state, and a gap may exist between one end of the second pushing piece 85 far away from the first pushing piece 81 and the second housing 14, and the gap is maintained in such a stable state to avoid the interference of the expansion piece 80 to the sliding of the second housing 14 relative to the first housing 12.

In combination with the arrangement that the first pushing member 81 and the second pushing member 85 are respectively in threaded connection with the connecting member 83, the connecting member 83 can conveniently adjust the distance between the first pushing member 81 and the second pushing member 85. Under the condition that the structural parameters of the first elastic member 871 and the second elastic member 873 are the same, the connecting member 83 can conveniently adjust the initial compression amount of the first elastic member 871 and the second elastic member 873 to ensure the stable state of the first pushing member 81 and the second pushing member 85, thereby preventing the interference of the expansion member 80 to the sliding of the second housing 14 relative to the first housing 12. In other words, the amount of compression of the first elastic member 871 and the second elastic member 873 can be easily adjusted by screwing the connecting member 83 with the first pusher 81 and the second pusher 85, and thus the elastic member is suitable for different electronic apparatuses 100, and the elastic member 80 can be adjusted adaptively for electronic apparatuses 100 with gaps of different sizes, thereby improving the versatility of the extensible member 80. After the second pushing member 85 extends into the slot 14a, the compression amount of the first elastic member 871 increases and generates an elastic restoring force, the compression amount of the second elastic member 873 decreases, the second elastic member 873 may generate an elastic restoring force or may not generate an elastic restoring force, and the first elastic member 871 may cause the expansion member 80 to generate a movement tendency of exiting the slot 14 a.

During the process of switching the second housing 14 from the second position to the first position, the extensible member 80, the first elastic member 871 and the second elastic member 873 move with the first housing 12 relative to the second housing 14. In the first position, the engagement of the telescoping member 80 with the catch 14a places the first resilient member 871 in compression. When the engagement between the retractable member 80 and the engaging slot 14a needs to be released, the first elastic member 871 can release elastic potential energy and drive the retractable member 80 to reset, so that the second pushing member 85 is pulled out of the engaging slot 14 a. In the embodiment where the second elastic member 873 generates elastic restoring force, the second elastic member 873 can also assist in driving the retractable member 80 to return, so that the second pushing member 85 is disengaged from the engaging slot 14 a. After second pushing member 85 is disengaged from slot 14a, second housing 14 and first housing 12 may slide relative to each other again, so that second housing 14 can be switched from the first position to the second position.

In other embodiments, the first elastic member 871 can be an elastic column or an elastic sheet, and the second elastic member 873 can also be an elastic sheet or an elastic column. It is understood that one of the first elastic member 871 and the second elastic member 873 may be absent, and one of the first pusher 81 and the second pusher 85 and the connecting member 83 may be absent. In other words, the first pushing member 81 or the second pushing member 85 may be extended and used to cooperate with the locking groove 14a, and one of the first elastic member 871 and the second elastic member 873 may be absent.

Referring to fig. 13, the driving mechanism 60 includes a driver 61 and a movable member 63 linked with an output end of the driver 61, the driver 61 is connected to the first housing 12, and the movable member 63 is connected to the second housing 14 to drive the second housing 14 to switch between a first position and a second position relative to the first housing 12 (refer to fig. 8). In the process of switching the second housing 14 from the second position to the first position, the movable member 63 drives the telescopic member 80 to slide relative to the first housing 12 when approaching the first position, so as to limit the second housing 14 by the telescopic member 80.

In this embodiment, the driver 61 may be a stepping motor, and the driving mechanism 60 may further include a screw (not shown) and a nut (not shown), where the stepping motor drives the screw to rotate, and the screw further drives the movable member 63 to move through the nut, so as to drive the second housing 14 to slide relative to the first housing 12. Of course, in some embodiments, a gear reduction mechanism may be disposed between the output end of the stepping motor and the lead screw. In other embodiments, the driving mechanism 60 may include a gear and a rack, the driver 61 drives the gear to rotate, the gear drives the rack to move, and the rack is connected to the movable member 63 to realize the sliding of the second housing 14 relative to the first housing 12.

Referring to fig. 12 and 13, the movable member 63 defines a sliding slot 63a, the sliding slot 63a extends along the moving direction of the second housing 14 relative to the first housing 12, and one end of the telescopic member 80 is slidably engaged with the sliding slot 63 a. Referring to fig. 11, one end of the first pushing member 81 away from the second pushing member 85 may be provided with a protrusion 81a, and the protrusion 81a is disposed through the sliding groove 63a and slidably engaged with the sliding groove 63 a. When the driver 61 drives the moving member 63 to move relative to the first housing 12, the protrusion 81a moves along the sliding groove 63a, and the groove wall of the sliding groove 63a can be used to press the expansion member 80 and drive the expansion member 80 to slide relative to the first housing 12, so that the second pushing member 85 of the expansion member 80 can enter the engaging groove 14a and engage with the engaging groove 14 a.

Specifically, in the present embodiment, the chute 63a may include a first section 63a1 and a second section 63a2 that are in communication. First segment 63a1 is substantially straight channel-shaped, and second segment 63a2 is closer to second pusher 85 than first segment 63a1 in a direction perpendicular to the direction of movement of second housing 14 relative to first housing 12. During the process of extending free portion 20b out of housing assembly 10, as projection 81a of first pusher 81 moves along first segment 63a1, the opposite end of telescoping member 80 remains outside of slot 14a, thereby preventing telescoping member 80 from interfering with the movement of second housing 14 relative to first housing 12. After the protrusion 81a of the first pushing element 81 enters the second section 63a2, the locking groove 14a of the second housing 14 moves relative to the first housing 12 to reach a position corresponding to the second pushing element 85, and the movable element 63 presses the telescopic element 80 through the groove wall of the second section 63a2 so that the second pushing element 85 of the telescopic element 80 enters the locking groove 14 a. After the second pushing member 85 enters the clamping groove 14a, the position of the second housing 14 is fixed relative to the position of the first housing 12, and the second housing 14 can be reliably positioned in the first housing 12, so as to prevent the moving parts and other moving parts of the driving mechanism 60 from being damaged when the first housing 12 or the second housing 14 is accidentally impacted.

Further, referring to fig. 13, the second housing 14 is provided with a limiting groove 14b, and the limiting groove 14b has a suitable width in the moving direction of the second housing 14 relative to the first housing 12. The movable member 63 is slidably fitted in the stopper groove 14 b. In the process that the second housing 14 moves from the second position to the first position relative to the first housing 12, the driver 61 drives the movable member 63 to abut against the groove wall of the end of the limiting groove 14b away from the driver 61, so as to drive the second housing 14 to move forward relative to the first housing 12 (i.e. in the direction from the second position to the first position) and drive the free portion 20b to extend out of the housing assembly 10. When the movable member 63 approaches the first position, the second section 63a2 of the sliding slot 63a drives the second pushing member 85 into the slot 14a, so that the positions of the second housing 14 and the first housing 12 can be fixed relatively, and damage to the moving parts and other moving parts of the driving mechanism 60 caused by accidental impact on the first housing 12 or the second housing 14 can be prevented.

When the position of the telescopic member 80 on the second housing 14 needs to be released, the driver 61 may drive the movable member 63 to move toward the other end opposite to the position-limiting groove 14b (i.e., the end close to the driver 61) so that the protrusion 81a of the first pushing member 81 of the telescopic member 80 exits the second section 63a2 and enters the first section 63a1, and the reset member 87 may drive the telescopic member 80 to reset, so that the second pushing member 85 is out of the clamping groove 14a, thereby releasing the cooperation between the telescopic member 80 and the second housing 14. In the moving direction of the second housing 14 relative to the first housing 12, the length of the limiting groove 14b can be set manually, so as to ensure that the retractable member 80 can be pulled out of the slot 14a after the movable member 63 moves a distance toward the driver 61 relative to the second housing 14. After the movable member 63 abuts against the opposite end of the limiting groove 14b, the second housing 14 can be driven to move in the opposite direction (i.e. the direction from the first position to the second position) relative to the first housing 12, and the free portion 20b can be driven to retract into the housing assembly 10.

In this embodiment, the second housing 14 may further include a guide groove (not shown) for the movable member 63 to move relative to the second housing 14, so as to ensure the movement stability of the movable member 63 and prevent the movable member 63 from deflecting during the movement relative to the second housing 14. Of course, the provision of the guide groove is not essential, and the movement of the movable member 63 relative to the second housing 14 can be made smooth by, for example, a lead screw or a rack of the drive mechanism 60.

In the present embodiment, two telescopic members 80 are provided, and the two telescopic members 80 may be arranged in axial symmetry with respect to the moving direction of the second housing 14 with respect to the first housing 12. The movable member 63 of the driving mechanism 60 may have two sliding slots 63a disposed at intervals, and the two retractable members 80 correspond to the two sliding slots 63a one by one, and each retractable member 80 may have a first elastic member 871 and a second elastic member 873. The two telescopic members 80 can be pressed by the same movable member 63, thereby reducing the number of the driving mechanisms 60, simplifying the structure of the electronic device 100 and saving the internal installation space of the electronic device 100. This arrangement also improves the operational reliability of the extendable members 80 to ensure that the first housing 12 and the second housing 14 are more reliably retained in the first position.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
