Referring to fig. 1 and fig. 2, the electronic device 10 of the present embodiment includes a housing assembly 100, the housing assembly 100 is a hollow structure, the electronic device 10 may further include a circuit board (not shown) and a battery (not shown), and the circuit board (not shown) and the battery (not shown) may be disposed on the housing assembly 100. The circuit board may integrate the processor, power management module, memory unit, baseband chip, etc. of the electronic device 10. The electronic device 10 includes a flexible display (not shown) disposed on the housing assembly 100 and in communication with the circuit board, and a battery capable of powering the flexible display and the electronic components on the circuit board. Of course, the electronic device 10 may further include a camera module, where the camera module is communicatively connected to the circuit board, and the battery is capable of supplying power to the camera module. It is understood that the electronic device 10 of the embodiments 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 10. In the embodiment of the present application, a mobile phone will be described as an example.

As shown in connection with fig. 1 and 2, in the present embodiment, the housing assembly 100 includes a first housing 110 and a second housing 120, and the second housing 120 and the first housing 110 are capable of relative movement, thereby providing the housing assembly 100 with a collapsed state and an expanded state. Specifically, in the present embodiment, the second case 120 and the first case 110 are slidably coupled. In other words, the second housing 120 can slide with respect to the first housing 110.

Further, the second housing 120 is capable of sliding relative to the first housing 110 to a first position (as shown in fig. 1) and a second position (as shown in fig. 2). In combination with the figure, when the second housing 120 is in the second position, the housing assembly 100 is in the unfolded state, and the electronic device 10 is in the unfolded state, so that a relatively large display area can be obtained, so as to enhance the use experience of the electronic device 10. When the second housing 120 is in the first position, the housing assembly 100 is in the collapsed state, and the electronic device 10 is in the collapsed state and has a relatively small external dimension, so that the portable electronic device is convenient to carry. It is understood that in the embodiments that follow this application, the first position, the second position, and the like refer to the relative positions of the second housing 120 and the first housing 110. For simplicity, the similar expression "the second housing 120 is located at the first position" or "when at the first position" means that the second housing 120 is located at the first position with respect to the first housing 110, and the similar expression "the second housing 120 is located at the second position" or "when at the second position" means that the second housing 120 is located at the second position with respect to the first housing 110.

In the present embodiment, the position of the end of the second case 120 remote from the first case 110 and the end of the first case 110 remote from the second case 120 can be more clearly determined with reference to the second position. Taking the example as a drawing, when the second housing 120 is at the second position, the leftmost side of the electronic device 10 in the width direction is the end of the first housing 110 away from the second housing 120, and the rightmost side of the electronic device 10 in the width direction is the end of the second housing 120 away from the first housing 110.

In the present embodiment, when the second case 120 is in the second position, the overall width of the electronic device 10 is greater than that in the first position, so that the width dimension of the exposed flexible display screen is variable. In other words, the electronic apparatus 10 is variable in size in the width direction. In such an embodiment, an interface of the electronic apparatus 10, 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, the overall length of the electronic device 10 is greater than the length in the first position when the second housing 120 is in the second position, such that the length dimension of the exposed flexible display screen is variable. In other words, the electronic device 10 is variable in size in the length direction. In such an embodiment, an interface of the electronic device 10, such as a data line jack or a charging line jack or a headset jack, may be provided at the end in the length direction.

The flexible display screen may include a fixing portion and a free portion that are disposed opposite to each other, where the fixing portion is disposed on the first shell 110 and is fixed relative to a position of the first shell 110, and the free portion is accommodated in the shell assembly 100, so that a portion of the flexible display screen is hidden in the shell assembly 100, and a portion of the flexible display screen hidden in the shell assembly 100 may not be used for displaying. In other words, movement of the second housing 120 relative to the first housing 110 may cause at least a portion of the free portion to be deployed within the first housing 110 or the free portion deployed within the first housing 110 to be retracted within the housing assembly 100.

It will be appreciated that in the embodiments of the present application, the positions of the two objects are relatively fixed, that is, the two objects cannot generate a relative motion under normal conditions or the relative motion between the two objects is negligible, and the two objects with relatively fixed positions may be physically connected directly, or may be indirectly connected through an intermediate structure. Taking the fixing portion and the first shell 110 as examples, the fixing portion and the first shell 110 may be fixed relatively, that is, the fixing portion and the first shell 110 are in direct contact, for example, the fixing portion and the first shell 110 may be directly fixed by using a threaded fastener or a clamping manner, or the fixing portion may be indirectly fixed to the first shell 110 by using an adhesive layer, an intermediate connection plate, or other structures.

It should be understood that the fixed portion and the free portion can be distinguished in the following manner, when the second housing 120 is at the first position relative to the first housing 110, the portion of the flexible display exposed outside the housing assembly 100 is the fixed portion of the flexible display, and the portion of the flexible display accommodated in the housing assembly 100 can be regarded as the free portion. In some embodiments, when the second housing 120 is located at the first position, the fixing portion exposed outside the housing assembly 100 is substantially rectangular, and the size of the fixing portion may be comparable to that of a display screen of a typical smart phone, so that the electronic device 10 is convenient to carry and use.

Further, the second housing 120 may include a rear cover that covers the free portion of the flexible display screen in the first position. The rear cover may provide a light-transmitting area, and the portion of the flexible display screen that is received in the housing assembly 100 in the first position may also be used for displaying, so that a user may view information displayed by the flexible display screen from the light-transmitting area, and further expand a usage scenario of the electronic device 10. For example, in this embodiment, the electronic device 10 can realize functions such as self-timer, video call, and the like by using a rear camera module without providing a front camera. The light-transmitting region may be made of transparent glass or may be an opening of the rear cover. After the second housing 120 slides to the second position relative to the first housing 110, at least a portion of the flexible display screen housed in the housing assembly 100 is exposed. The exposed flexible display screen may be used for display such that the electronic device 10 has a relatively large display area to enhance the user's use experience.

As shown in fig. 1 to 8, in the embodiment of the present application, the electronic device 10 includes a guide plate 200 and a locking mechanism 300. The guide plate 200 is disposed inside the shell assembly 100, and the guide plate 200 is forced to drive the shell assembly 100 to be unfolded or folded. The guide plate 200 has a stepped guide surface 210, and the guide surface 210 includes a first guide surface 220 and a second guide surface 230. The locking mechanism 300 is disposed inside the housing assembly 100 and abuts against the guiding surface 210. During the process of folding and unfolding the shell assembly 100, the second guide surface 230 moves to the locking mechanism 300 and pushes the locking mechanism 300 to move so as to lock the shell assembly 100 to the unfolded state. The guide plate 200 can move a predetermined stroke relative to the housing assembly 100 to move the first guide surface 220 to the locking mechanism 300, and the locking mechanism 300 is reset to unlock the housing assembly 100.

It can be appreciated that the locking mechanism 300 is configured to lock the case assembly 100 in the unfolded state when the case assembly 100 is in the unfolded state, so that when the electronic device 10 receives an external impact force in the closing direction, the locking mechanism 300 can bear the acting force, so that the impact force is absorbed by the case assembly 100 together, thereby avoiding the damage of the electronic device 10 caused by large relative movement generated by direct conduction of the acting force to other moving parts, improving the reliability and stability of the electronic device 10, and improving the impact resistance of the electronic device 10.

Specifically, the guide plate 200 drives the second housing 120 to slide between the first position and the second position relative to the first housing 110 along the first direction under the action of the force, and the locking mechanism 300 locks the first housing 110 and the second housing 120 so that the two housings cannot move relative to each other when the second housing 120 is at the second position.

Specifically, the first guide surface 220 and the second guide surface 230 extend along a first direction, and form a height difference in a second direction perpendicular to the first direction, so that the guide surface 210 is stepped.

It is understood that in this application, the first direction is specifically the width direction of the electronic device 10, and the second direction is specifically the length direction of the electronic device 10.

It can be appreciated that after the guide plate 200 abuts against the second shell 120 and moves the second shell 120 to the second position relative to the first shell 110, the guide plate 200 can abut against the second shell 120 after moving a predetermined stroke relative to the second shell 120, so that the second shell 120 moves from the second position to the first position relative to the first shell 110. That is, in the process that the guide plate 200 drives the second housing 120 to move from the second position to the first position, the guide plate 200 moves an idle stroke relative to the second housing 120, and then the belt can drive the second housing 120 to move. Specifically, the second housing 120 is provided with an opening 121, one end of the guide plate 200 is connected with a stopper 240, the stopper 240 extends into the opening 121, and can be abutted against two inner walls of the opening 121 along the first direction, so that the guide plate 200 can be abutted against the second shell 120 to drive the second shell 120 to move. Specifically, the minimum distance between the two inner walls of the opening 121 along the first direction is greater than the maximum thickness of the stop 240 along the first direction, so that the stop 240 can only abut against one of the two inner walls of the opening 121 along the first direction during the movement of the second shell 120 relative to the first shell 110, and thus, the stroke from the abutment of the stop 240 with one inner wall of the opening 121 along the first direction to the abutment with the other inner wall is the predetermined stroke.

It is understood that the locking mechanism 300 abuts against the guiding surface 210 along the second direction. During the movement of the second case 120 along the first direction by the guide plate 200, the contact position of the locking mechanism 300 and the guide surface 210 is changed along with the movement of the guide plate 200 along the first direction, so that the first guide surface 220 can be moved to the locking mechanism 300 or the second guide surface 230 can be moved to the locking mechanism 300. Because of the difference in height between the first guide surface 220 and the second guide surface 230 in the second direction, the locking mechanism 300 moves in the second direction under the action of the guide surface 210, and in the second direction, the locking mechanism 300 may move toward the guide surface 210 or move away from the guide surface 210. Specifically, the second guide surface 230 protrudes from the first guide surface 220, and when the locking mechanism 300 moves from the first guide surface 220 to the second guide surface 230, the second guide surface 230 pushes the locking mechanism 300 to move away from the guide surface 210 to lock the second case 120 at the second position, and when the locking mechanism 300 moves from the second guide surface 230 to the first guide surface 220, the locking mechanism 300 moves toward the guide surface 210 to reset under the elastic action, thereby unlocking the second case 120. In other embodiments, the first guide surface 220 may protrude from the second guide surface 230, or the locking mechanism 300 may unlock the second housing 120 when moving away from the guide surface 210, and lock the second housing 120 when moving toward the guide surface 210. Specifically, when the second housing 120 is moved from the second position to the first position, the guide plate 200 is first slid for a predetermined stroke relative to the second housing 120, and in this process, the locking mechanism 300 is moved from the second guide surface 230 to the first guide surface 220 to unlock the second housing 120, and then the guide plate 200 is abutted against the second housing 120 to drive the second housing 120 to move relative to the first housing 110.

Specifically, the guide surface 210 includes a transition guide surface 250, and the transition guide surface 250 is connected between the first guide surface 220 and the second guide surface 230 and smoothly connected with the first guide surface 220 and the second guide surface 230. By providing the transition guide surface 250, the locking mechanism 300 can be smoothly transitioned when sliding between the first guide surface 220 and the second guide surface 230. It will be appreciated that during movement of the lock mechanism 300 along the first guide surface 220, the lock mechanism 300 does not move in the second direction because the first guide surface 220 extends in the first direction without a height difference. During the movement of the locking mechanism 300 along the second guide surface 230, the locking mechanism 300 does not move in the second direction because the second guide surface 230 extends in the first direction without a height difference. In this manner, the latch mechanism 300 does not move in the second direction until the latch mechanism 300 climbs from the first guide surface 220 to the second guide surface 230 through the transition guide surface 250, or until the latch mechanism 300 falls from the second guide surface 230 to the first guide surface 220 through the transition guide surface 250.

In this embodiment, two opposite sides of the guide plate 200 are provided with guide surfaces 210, and two locking mechanisms 300 are respectively located at two sides of the guide plate 200 and correspond to the two guide surfaces 210 one by one. In this way, the two locking mechanisms 300 are respectively disposed at two sides of the guide plate 200 to lock the second case 120 at two positions, that is, to make the second case 120 have two supporting points that receive force when receiving an external force, so as to ensure the locking stability of the electronic device 10.

The specific structure of the lock mechanism 300 will be described below.

With continued reference to fig. 3-9, in some embodiments, the housing assembly 100 is provided with a stop 122. The locking mechanism 300 includes a holding component 310 and a locking component 330 connected to the holding component 310, where the holding component 310 holds against the guide surface 210, and the locking component 330 cooperates with the limiting member 122 to lock the shell component 100 in the deployed state. The movement stroke of the abutment assembly 310 is smaller than the movement stroke of the locking assembly 330. It can be appreciated that the height difference between the first guide surface 220 and the second guide surface 230 is equal to the movement stroke of the abutting component 310 along the second direction, so that under the condition that the given stroke is fixed, the movement stroke of the locking component 330 along the second direction is increased, and the movement stroke of the abutting component 310 along the second direction is reduced, so that under the condition that the locking requirement of the shell component 100 is met, the height difference between the first guide surface 220 and the second guide surface 230 is reduced, and the transition between the first guide surface 220 and the second guide surface 230 is gentle, so that the abutting component 310 is not subjected to larger resistance due to overlarge height difference during climbing along the guide surface 210, and the problem of abnormal sound due to instantaneous drop caused by overlarge height difference during falling along the guide surface 210 during the falling of the abutting component 310 is solved, and the silencing effect during the relative movement of the first shell 110 and the second shell 120 is better. Specifically, the limiting member 122 is disposed on the second housing 120, and the locking assembly 330 cooperates with the limiting member 122 to lock the second housing 120 in the second position relative to the first housing 110.

In the present application, the locking mechanism 300 includes a traction rope 350, and the abutting component 310 includes an abutting piece 311 abutting against the guiding surface 210 and a driving wheel 312 connected to the abutting piece 311. The pull cord 350 is coupled to the locking assembly 330 after passing around the drive wheel 312. Specifically, a first end of the pull-cord 350 is fixed relative to the first housing 110, and a second end of the pull-cord 350 is coupled to the locking assembly 330 after bypassing the drive wheel 312. After the abutting piece 311 and the driving wheel 312 synchronously move along the second direction by the first displacement S1, the second end and the locking assembly 330 connected with the second end need to move along the second direction by the second displacement S2, and s2=2s1, so that the movement stroke of the abutting assembly 310 along the second direction is smaller than the movement stroke of the locking assembly 330 along the second direction through the cooperation of the driving wheel 312 and the traction rope 350.

Further, the locking mechanism 300 includes a first elastic member 360 and a second elastic member 370, wherein the first elastic member 360 applies a first elastic force F1 towards the guiding surface 210 to the abutment assembly 310, and the second elastic member 370 applies a second elastic force F2 away from the guiding surface 210 to the locking assembly 330, wherein F1>2F2. It will be appreciated that under the elastic action of the first elastic member 360, the abutment member 310 has a tendency to move toward the guide surface 210 so as to maintain abutment with the guide surface 210, and under the elastic action of the second elastic member 370, the locking member 330 has a tendency to move away from the guide surface 210, so that under the cooperation of the first elastic member 360 and the second elastic member 370, the traction rope 350 can be kept taut, thereby achieving linkage between the abutment member 310 and the locking member 330. In addition, during the movement of the abutment assembly 310 from the second guide surface 230 to the first guide surface 220, the first elastic member 360 elastically acts on the abutment assembly 310, which needs to overcome the elastic force of the second elastic member 370 to force the abutment assembly 310 to move toward the guide surface 210, so that the first elastic force of the first elastic member 360 is greater than the second elastic force of the second elastic member 370 by a factor of 2.

As shown in fig. 7 and 10, in particular, the abutment assembly 310 includes a transmission member 313, and the transmission member 313 is connected between the abutment member 311 and the transmission wheel 312; the first elastic member 360 elastically acts on the transmission member 313 to elastically support the supporting member 311 against the guiding surface 210. By providing the transmission member 313, the connection between the abutment member 311 and the transmission wheel 312 can be realized, so that both move synchronously. Specifically, the first housing 110 may be fixedly provided with a first guide block 111, and the abutting component 310 is accommodated inside the first guide block 111, where the first guide block 111 guides the driving member 313 along the second direction, so as to guide the entire abutting component 310 along the second direction. Specifically, the transmission member 313 may be configured to include a guide rod 314 and a connection portion 315, the connection portion 315 connects the supporting member 311 and the driving wheel 312, the first elastic member 360 is sleeved on the guide rod 314, and applies a first elastic force F1 towards the guiding surface 210 to the connection portion 315. Specifically, the first elastic member 360 is a spring, and one end thereof abuts against the first guide block 111, and the other end abuts against the connecting portion 315. In other embodiments, the first elastic member 360 may be a tension spring, an elastic column, or another type of elastic element such as a spring plate. Specifically, the first guide block 111 may be provided with a guide hole through which the guide rod 314 passes, or may be provided with a guide chamber that accommodates the connection portion 315 and guides the connection portion 315. Specifically, the drive wheel 312 is a pulley rotatable relative to the drive member 313, thereby reducing wear of the pull-cord 350 as it moves relative to the drive wheel 312.

In this embodiment of the present application, the supporting member 311 can roll relative to the guide surface 210, so that rolling friction is formed between the supporting member 311 and the guide surface 210, abrasion of the supporting member 311 to the guide surface 210 is reduced, and meanwhile, resistance force applied to the supporting member 311 moving along the guide surface 210 is reduced, so that smooth mute motion between the supporting member 311 and the guide plate 200 is realized. It should be noted that, in other embodiments, sliding friction may be between the abutment member 311 and the guide surface 210, and in this case, the abutment member 311 and the guide surface 210 need to be configured as a metal member that is more wear-resistant. In order to reduce the sliding frictional resistance between the holding member 311 and the guide surface 210, the contact area between the holding member 311 and the guide surface 210 may be reduced, for example, the holding member 311 may be in point contact or line contact with the guide surface 210.

Specifically, since the abutting piece 311 is connected to the driving wheel 312 through the driving piece 313, the abutting piece 311 may be provided as a bearing connected to the driving piece 313. The bearing generally has an inner ring and an outer ring, and the inner ring and the outer ring can rotate relative to each other. By fixedly connecting the inner ring of the bearing to the transmission member 313, the outer ring is in rolling contact with the guide surface 210. Specifically, the bearing outer ring may be configured of a metal material, and may also be a non-metal material, such as Polyoxymethylene (POM). After the supporting member 311 is set as a bearing, the service life of the electronic device 10 is greatly prolonged, and the service life test is passed for 20W times.
