Description

Electronic device

Technical Field

The present application relates to the field of terminal technologies, and in particular, to an electronic device.

Background

The flexible screen has the characteristic of a flexible display, which makes it possible to provide an electronic apparatus equipped with a flexible screen that is stretchable. When the flexible screen of the electronic equipment is in a folded state, the electronic equipment has a relatively small overall dimension; when the flexible screen is in the unfolded state, the electronic device has a relatively large display area. Due to the relative movement of at least part of the flexible screen with respect to the housing of the electronic device, the electronic device in the unfolded state is susceptible to damage of the moving parts when subjected to an impact, such as an accidental drop.

Disclosure of Invention

The embodiment of the application provides electronic equipment to improve the shock resistance of the electronic equipment.

An electronic device, comprising:

the shell assembly comprises a first shell and a second shell connected to the first shell, and one of the first shell and the second shell is provided with a clamping groove;

the flexible display screen comprises a fixed part and a free part which are oppositely arranged, the fixed part is connected with the first shell, and the free part bypasses one end of the second shell, which is far away from the first shell, and is contained in the shell component; and

a locking mechanism including a movable member connected to the other of the first housing and the second housing;

the second shell is movably matched with the first shell to be switched between a first position and a second position, and the movable piece is driven to move relative to the shell component; when the movable piece is in the first position, at least part of the free portion is unfolded outside the second shell, and the movable piece is matched with the clamping groove to limit the second shell to move to the second position; in a second position, the free portion deployed outside the second housing is received within the housing assembly.

In the electronic device, the second shell can be switched between the first position and the second position relative to the first shell, and the movable piece can be driven to move relative to the shell component so as to be matched with the clamping groove at the first position to limit the second shell to move to the second position. When the second shell is in the first position, namely the electronic equipment is in the unfolding state, after the electronic equipment is impacted, such as accidentally falls, the matching of the movable part and the clamping groove can play an effective locking role, so that the impact force is absorbed by the first shell and the second shell together, and other moving parts are prevented from generating large relative movement to protect the moving parts, thereby improving the impact resistance of the electronic equipment.

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 50, the camera module 50 is connected to the circuit board in communication, and the battery can supply power to the camera module 50. It is understood that the electronic device 100 of the embodiment of the present application includes, but is not limited to, a mobile phone, a tablet computer, and other terminal devices 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, 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. 7, in the present embodiment, the guide 30 has a circular shaft shape. The electronic device 100 may further include a pulley 61 and a traction belt 63, the guide member 30 is rotatably connected to an end of the second housing 14 away from the first housing 12, and the pulley 61 is rotatably connected to an end of the second housing 14 away from the guide member 30. One end of the traction belt 63 is connected to the free portion 20b, and the other end is wound around the pulley 61 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 61 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 63 relative to the pulley 61 are both 2 d. Therefore, the cooperation of the guide 30, the pulley 61 and the traction belt 63 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 61 on the traction belt 63, 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 70, the driving mechanism 70 may be disposed in the housing assembly 10, and the driving mechanism 70 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 70 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 position and the second position may be achieved by providing a stop 80 on the second housing 14 or the first housing 12 or the guide 30.

Specifically, in the present embodiment, the stopper 80 is connected to the first housing 12. In the first position, the second housing 14 abuts against the stopper 80, so as to limit the moving range of the second housing 14 in the first housing 12 and to stop the second housing 14 at the first position. In the present embodiment, an end of a slide rail for sliding the first casing 12 and the second casing 14 relative to each other may be used as the stopper 80. Of course, it is understood that the position limiting member 80 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 another embodiment, the stopper 80 may be connected to the second housing 14, and the first housing 12 may abut against the stopper 80 in the first position, and this configuration may also reliably stop the second housing 14 at 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 implemented using other limiting structures such as spring tabs.

Referring to fig. 9, in the present embodiment, one of the first housing 12 and the second housing 14 is provided with a card slot 14 a. Referring to fig. 10, the electronic device 100 may further include a latch mechanism 90, the latch mechanism 90 includes a movable member 91 and a reset member 93, the movable member 91 is connected to the other of the first housing 12 and the second housing 14, and the reset member 93 is connected to at least one of the housing assembly 10 and the movable member 91 and is used for resetting movement of the movable member 91. The reset movement may be simply understood as a movement of the movable member 91 to return to the initial position. For example, in the present embodiment, the movable member 91 may be considered to be in the initial position when in the second position; the movable member 91 can be driven to move to another position relative to the housing assembly 10, and the reset member 93 can be used to drive the movable member 91 to return to the initial position again.

Referring to fig. 11, the present application will be described by taking an example in which the engaging groove 14a is disposed on the second housing 14, and the movable element 91 and the reset element 93 are disposed on the first housing 12. In the first position, the movable member 91 can cooperate with the locking slot 14a to limit the second housing 14 from moving to the second position. In other words, when the flexible display screen 20 is unfolded to be in a large screen display state, the cooperation between the movable element 91 and the slot 14a can fix the positions of the first housing 12 and the second housing 14 relatively, 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 movable piece 91 is engaged with the engaging groove 14a, the first housing 12 and the second housing 14 can be simply regarded as a single body, and thus the impact force can be absorbed by the first housing 12 and the second housing 14 to prevent the moving parts of the driving mechanism 70 from being damaged by the impact force.

It is understood that, in other embodiments, the locking slot 14a may be disposed in the first housing 12, and the movable member 91 and the reset member 93 may be disposed in the second housing 14, which will not be described in detail herein.

In the present embodiment, the return member 93 is a spring, and the return member 93 is connected to the movable member 91 and the first housing 12. During the process of switching the second housing 14 from the second position to the first position, the movable member 91 and the reset member 93 move with the first housing 12 relative to the second housing 14. In the first position, the engagement of the movable member 91 with the engaging slot 14a can place the reset member 93 in a stretched state. When the movable element 91 needs to be disengaged from the engaging slot 14a, the reset element 93 in the stretching state can release the elastic potential energy and drive the movable element 91 to reset, so that the movable element 91 is disengaged from the engaging slot 14 a. After the movable member 91 is disengaged from the engaging slot 14a, the second housing 14 and the first housing 12 can slide relative to each other again, so that the second housing 14 can be switched from the first position to the second position.

It is understood that in other embodiments, after changing the position of the reset member 93, the engagement of the movable member 91 with the slot 14a in the first position may also cause the reset member 93 to be in a compressed state. When the movable member 91 needs to be disengaged from the engaging slot 14a, the restoring member 93 in the compressed state releases the elastic potential energy to drive the movable member 91 to restore. Of course, in other embodiments, the restoring member 93 may be replaced by a spring sheet or an elastic column. Of course, the reset member 93 may also be replaced by a magnetic member, that is, two magnetic poles of the same name may generate magnetic repulsion or two magnetic poles of different name may generate magnetic attraction to drive the movable member 91 to reset.

Further, referring to fig. 10, in an embodiment, the movable member 91 is substantially rod-shaped, and a middle portion of the movable member 91 is rotatably connected to the first housing 12. For example, the movable member 91 may be pivotally connected to the first housing 12 by a pin. The reset member 93 is connected to one end of the movable member 91, and the other end of the movable member 91 may be in a suspended state. After the second housing 14 is switched from the second position to the first position, one end of the movable member 91 can be driven to swing relative to the first housing 12 when the first position is reached, so that the other end of the movable member 91 extends into the slot 14a of the second housing 14, thereby limiting the second housing 14 by the movable member 91.

Referring to fig. 12, the driving mechanism 70 includes a driver 71 and a connecting member 73 coupled to an output end of the driver 71, the driver 71 is coupled to the first housing 12, and the connecting member 73 is coupled 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 (see fig. 8). After the second housing 14 is switched from the second position to the first position, the connecting member 73 drives the movable member 91 to swing relative to the first housing 12, so as to limit the position of the movable member 91 on the second housing 14.

In this embodiment, the driver 71 may be a stepping motor, and the driving mechanism 70 may further include a lead screw (not shown) and a nut (not shown), where the stepping motor drives the lead screw to rotate, and the lead screw further drives the connecting member 73 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 70 may include a gear and a rack, the driver 71 drives the gear to rotate, the gear drives the rack to move, and the rack is connected to the connecting member 73 to realize the sliding of the second housing 14 relative to the first housing 12.

Referring to fig. 12, the connecting member 73 may include a first connecting portion 731, a buffering member 733 and a second connecting portion 735, the first connecting portion 731 is coupled to the output end of the driver 71, the buffering member 733 is connected between the first connecting portion 731 and the second connecting portion 735, and the second connecting portion 735 is connected to the second housing 14. After the second housing 14 is switched from the second position to the first position, that is, when the second housing 14 and the first housing 12 are no longer relatively far away from each other, the driver 71 may drive the first connection portion 731 to approach the second connection portion 735 and compress the buffer 733, and the first connection portion 731 drives the movable element 91 to swing relative to the first housing 12, with reference to fig. 10 and 11, an end of the movable element 91 far away from the first connection portion 731 extends into the slot 14a of the second housing 14, so as to limit the second housing 14 through cooperation between the movable element 91 and the slot 14a, and prevent the movable element of the driving mechanism 70 from being damaged when the first housing 12 or the second housing 14 is accidentally impacted.

When the position of the movable member 91 on the second housing 14 needs to be released, the driver 71 can drive the first connection portion 731 to be away from the second connection portion 735, so as to release the cooperation between the first connection portion 731 and the movable member 91, and the reset member 93 can drive the movable member 91 to reset.

In the present embodiment, the buffer 733 is a spring having a certain rigidity, and a critical acting force that can cause compression deformation or tensile deformation of the buffer 733 is not less than sliding resistance of the second case 14 with respect to the first case 12. In other words, under the condition that the movable element 91 is disengaged from the second housing 14, the buffering member 733 may be regarded as a rigid body, and when the driver 71 drives the second housing 14 to slide relative to the first housing 12, the amount of compressive deformation or tensile deformation generated by the buffering member 733 may be negligible, that is, when the second housing 14 slides relative to the first housing 12, the first connecting portion 731, the buffering member 733, and the second connecting portion 735 may be regarded as a whole, and this structural arrangement may improve the motion stability of the second housing 14 relative to the first housing 12, and prevent the shake phenomenon from occurring during the motion.

After the second housing 14 slides to the first housing 12 to the first position, the position of the second connecting portion 735 is fixed relative to the second housing 14, and the driver 71 can overcome the deformation resistance of the buffer 733 to compress the buffer 733 so as to move the first connecting portion 731 to the second connecting portion 735. In this process, the first connecting portion 731 can abut against one end of the movable member 91 of the locking mechanism 90, so that the opposite end of the movable member 91 extends into the slot 14a, thereby realizing the matching between the movable member 91 and the slot 14a, and further utilizing the movable member 91 to limit the position of the second housing 14.

When the limiting effect of the movable element 91 on the second housing 14 needs to be removed, the driver 71 can drive the first connecting portion 731 to move in a direction away from the second connecting portion 735, the deformation of the buffer member 733 is recovered, and the pressing effect of the first connecting portion 731 on the movable element 91 disappears. Under the action of the reset member 93, the movable member 91 performs a reset movement, that is, the movable member 91 is disengaged from the engaging groove 14a, so that the limit of the movable member 91 on the second housing 14 can be released. The second housing 14 is slidable relative to the first housing 12 from a first position to a second position.

In this embodiment, the second housing 14 may be provided with a guide slot for the first connecting portion 731 to move relative to the second housing 14, so as to ensure the motion stability of the first connecting portion 731 and prevent the first connecting portion 731 from deflecting during the motion relative to the second connecting portion 735. Of course, the arrangement of the guide groove is not necessary, and for example, the movement of the first connecting portion 731 can be made smooth by a lead screw or a rack of the driving mechanism 70.

Further, referring to fig. 12, in the present embodiment, a protrusion 731a is disposed on a side of the first connection portion 731 facing the movable member 91, and the protrusion 731a can be regarded as a part of the first connection portion 731. During the process of sliding the second housing 14 from the second position to the first position relative to the first housing 12, the projection 731a does not press against the movable member 91. Therefore, the movable member 91 is kept out of the engaging groove 14a by the reset member 93, and the second housing 14 can move smoothly with respect to the first housing 12. After the second housing 14 reaches the first position, the driver 71 continues to drive the first connecting portion 731 to approach the second connecting portion 735, so that the protrusion 731a can generate a pressing effect on the movable member 91, and the movable member 91 further swings relative to the first housing 12 to enter the slot 14 a.

In the present embodiment, two sets of the locking mechanisms 90 are provided, and the two sets of the locking mechanisms 90 may be arranged in axial symmetry with respect to the moving direction of the second housing 14 relative to the first housing 12. The two sets of the movable members 91 of the locking mechanisms 90 can be pressed by the same connecting member 73, thereby reducing the number of the driving mechanisms 70, 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 locking mechanism 90, so that the first housing 12 and the second housing 14 are more reliably limited in the first position.

It will be appreciated that the return member 93 could alternatively be a torsion spring. Of course, the reset member 93 is not necessary, and in other embodiments, the movable member 91 may be an eccentric structure, and in the initial position, the eccentric structure keeps the movable member 91 in a state of being disengaged from the engaging groove 14 a; when the first connecting portion 731 presses against the movable element 91, the movable element 91 can also extend into the slot 14a and cooperate with the slot 14 a.

Referring to fig. 13, in another embodiment, the movable member 91 is slidably engaged with the first housing 12, and during the process of switching the second housing 14 from the second position to the first position, the movable member 91 is driven to slide relative to the first housing 12 when approaching the first position, so that the opposite end of the movable member 91 extends into the slot 14a of the second housing 14. The reset member 93 is used to drive the movable member 91 to disengage from the slot 14a, so that the second housing 14 can be switched from the first position to the second position. In other words, in this embodiment, during the process of moving the second housing 14 from the second position to the first position relative to the first housing 12, when approaching the first position, the movable member 91 is forced to slide relative to the first housing 12 to engage with the engaging slot 14a of the second housing 14.

Specifically, in this embodiment, the connecting member 73 may be a one-piece structure, and the edge thereof is provided with a recessed area 73 a. During the switching of the second housing 14 from the second position to the first position, one end of the movable member 91 is movable in the recessed area 73 a. When the second housing 14 is close to the first position, the movable element 91 is moved out of the recessed area 73a and abuts against the connecting element 73, and the connecting element 73 can abut against the movable element 91 to make the movable element 91 slide relative to the first housing 12 and extend into the slot 14a of the second housing 14.

In such an embodiment, the movable member 91 may be rod-shaped, and the first housing 12 may be slotted for sliding engagement with the movable member 91. The reset member 93 may be a spring, a spring plate, an elastic column, or a magnetic member. In a case where the movable element 91 is not engaged with the slot 14a, the reset element 93 may keep the movable element 91 disengaged from the slot 14a, and the second housing 14 may slide relatively smoothly with respect to the first housing 12.

During the sliding of the second housing 14 relative to the first housing 12 from the second position to the first position, the recessed area 73a of the connecting member 73 may prevent the connecting member 73 from interacting with the movable member 91 during a front stroke (which may be set by an operator). Of course, the connecting member 73 may contact the movable member 91 without causing the movable member 91 to interfere with the sliding movement of the second housing 14 relative to the first housing 12. After the second housing 14 moves a certain distance relative to the first housing 12, the movable member 91 is disengaged from the recessed area 73a of the connecting member 73, and the connection of the connecting member 73 to the movable member 91 causes the movable member 91 to move in a direction away from the connecting member 73, so that the movable member 91 extends into the slot 14a and is limited at the first position, and the reset member 93 generates a restoring force required by the reset motion. In the first position, because the movable member 91 is engaged with the engaging groove 14a, the second housing 14 can be reliably retained in the first housing 12, and when an accidental impact occurs, the first housing 12 and the second housing 14 can absorb the impact force to prevent the moving parts of the driving mechanism 70 from being damaged.

In such an embodiment, an end of the connecting member 73 remote from the actuator 71 may be provided with a return member (not shown), by which the connecting member 73 is connected to the second housing 14. The return member may be a spring or a leaf spring or an elastic column, which has a certain rigidity and functions similar to the buffer member 733. When the second housing 14 is switched from the second position to the first position, the return element does not generate a restoring force, and when the second housing 14 reaches the first position, the movable element 91 and the engaging groove 14a are immediately engaged with each other to be limited to the first position. When the matching between the movable member 91 and the slot 14a needs to be released, the driver 71 drives the connecting member 73 to move in a direction away from the second housing 14, and the return member deforms so that the connecting member 73 can move a distance to the position of the driver 71, and the recessed area 73a of the movable member 91 is communicated with the movable member 91; under the action of the reset member 93, the movable member 91 is disengaged from the engaging groove 14a, so that the limiting function of the movable member 91 on the second housing 14 can be released, and the second housing 14 can move to the second position relative to the first housing 12.
