The circuit board can integrate the processor, the power management module, the storage unit and the baseband chip of the electronic device 10 and the like. The electronic device 10 includes a flexible display screen (not shown in the figure), the flexible display screen is arranged on the shell assembly 100 and is in communication connection with the circuit board, and the battery can supply power to the flexible display screen and the electronic components on the circuit board. Of course, the electronic device 10 can further include a camera module, the camera module is in communication connection with the circuit board, and the battery can supply power to the camera module. It can be understood that the electronic device 10 of the embodiment of the application can be but is not limited to a mobile phone, a tablet computer and other terminal devices or other portable electronic devices 10. In the embodiment of the application, a mobile phone is taken as an example for description.

[0043] Please refer to Figure 1 and Figure 2 , in the embodiment of the application, the shell assembly 100 includes a first shell 110 and a second shell 120, and the second shell 120 and the first shell 110 can move relatively, so that the shell assembly 100 has a folding state and an unfolding state. Specifically, in the embodiment, the second shell 120 and the first shell 110 are in sliding connection. In other words, the second shell 120 can slide relative to the first shell 110.

[0044] Further, the second shell 120 can slide relative to the first shell 110 to a first position (as shown in Figure 1 ) and a second position (as shown in Figure 2As shown in the figure, when the second shell 120 is in the second position, the shell assembly 100 is in an unfolded state, and the electronic device 10 is in an unfolded state and can obtain a relatively large display area to improve the use experience of the electronic device 10. When the second shell 120 is in the first position, the shell assembly 100 is in a folded state, and the electronic device 10 is in a folded state and has a relatively small size, which is convenient to carry. It can be understood that in the embodiments described later in the present application, the first position, the second position and similar expressions refer to the relative position of the second shell 120 and the first shell 110. For simplicity of description, the expression "the second shell 120 is in the first position" or "in the first position" refers to the relative position of the second shell 120 and the first shell 110 in the first position, and the expression "the second shell 120 is in the second position" or "in the second position" refers to the relative position of the second shell 120 and the first shell 110 in the second position.

[0045] In the present embodiment, with the second position as a reference, the position of the end of the second shell 120 away from the first shell 110 and the end of the first shell 110 away from the second shell 120 can be more clearly determined. For example, when the second shell 120 is in the second position, the leftmost side of the electronic device 10 in the width direction is the end of the first shell 110 away from the second shell 120, and the rightmost side of the electronic device 10 in the width direction is the end of the second shell 120 away from the first shell 110.

[0046] In the present embodiment, when the second shell 120 is in the second position, the overall width of the electronic device 10 is greater than the width in the first position, so that the width of the exposed flexible display screen can be variable. In other words, the size of the electronic device 10 in the width direction is variable. In this embodiment, the interface of the electronic device 10, such as a data line jack or a charging line jack or an earphone jack, can be arranged at the end in the width direction. In other embodiments, when the second shell 120 is in the second position, the overall length of the electronic device 10 is greater than the length in the first position, so that the length of the exposed flexible display screen can be variable. In other words, the size of the electronic device 10 in the length direction is variable. In this embodiment, the interface of the electronic device 10, such as a data line jack or a charging line jack or an earphone jack, can be arranged at the end in the length direction.

[0047] The flexible display screen can include a fixed part and a free part arranged oppositely, the fixed part is arranged on the first shell 110 and is relatively fixed with the first shell 110, and the free part is accommodated in the shell assembly 100, so that part of the flexible display screen is hidden in the shell assembly 100, and the part of the flexible display screen hidden in the shell assembly 100 can not be used for display. In other words, the movement of the second shell 120 relative to the first shell 110 can cause at least part of the free part to be unfolded on the first shell 110, or the free part unfolded on the first shell 110 to be retracted into the shell assembly 100.

[0048] It can be understood that, in the embodiments of the present application, the relative fixation of the positions of two objects means that the two objects cannot produce relative motion under normal circumstances or the relative motion between the two objects is negligible. The two objects with relatively fixed positions can be physically directly connected or indirectly connected through an intermediate structure. Taking the fixed part and the first shell 110 as an example, the fixed part and the first shell 110 have relatively fixed positions, which can be direct contact between the fixed part and the first shell 110, such as using threaded fasteners or clamping to achieve direct fixation of the fixed part and the first shell 110, or the fixed part can be indirectly fixed to the first shell 110 through an adhesive layer, an intermediate connecting plate or other structures.

[0049] It can be understood that the fixed part and the free part can be distinguished in the following manner: when the second shell 120 is in the first position relative to the first shell 110, the part of the flexible display screen exposed outside the shell assembly 100 is the fixed part of the flexible display screen, and the part of the flexible display screen accommodated in the shell assembly 100 can be considered as the free part. In some embodiments, when the second shell 120 is in the first position, the fixed part exposed outside the shell assembly 100 is substantially rectangular in shape, and its size can be comparable to the size of the display screen of a general smartphone, so that the electronic device 10 is convenient to carry and use.

[0050] Further, the second shell 120 can include a rear cover covering the free part of the flexible display screen when in the first position. The rear cover can be provided with a light-transmitting area, and the part of the flexible display screen accommodated in the shell assembly 100 when in the first position can also be used for display, so that the user can view the information displayed on the flexible display screen from the light-transmitting area, thereby expanding the use scenarios of the electronic device 10. For example, in such embodiments, the electronic device 10 does not need to be provided with a front-facing camera, and a rear-facing camera module can be used to realize functions such as selfie and video call. The light-transmitting area can be composed of transparent glass or can be formed by an opening of the rear cover. After the second shell 120 slides relative to the first shell 110 to the second position, at least part of the flexible display screen accommodated in the shell assembly 100 is exposed. The exposed flexible display screen can be used for display, so that the electronic device 10 has a relatively large display area, thereby improving the user's experience.

[0051] In combination with Figures 1 to 8As shown, in the embodiment of the present application, the electronic device 10 comprises a guide plate 200 and a locking mechanism 300. The guide plate 200 is arranged inside the shell assembly 100, and the guide plate 200 is driven to expand or contract the shell assembly 100. The guide plate 200 has a stepped guide surface 210, which comprises a first guide surface 220 and a second guide surface 230. The locking mechanism 300 is arranged inside the shell assembly 100 and abuts against the guide surface 210. During the process of expanding the shell assembly 100 from the contracted state to the expanded state, the second guide surface 230 moves to the locking mechanism 300 and drives the locking mechanism 300 to move to lock the shell assembly 100 in the expanded state. The guide plate 200 can move relative to the shell assembly 100 by a certain stroke to move the first guide surface 220 to the locking mechanism 300, and the locking mechanism 300 is reset to unlock the shell assembly 100.

[0052] It can be understood that the locking mechanism 300 is used to lock the shell assembly 100 in the expanded state when the shell assembly 100 is in the expanded state. In this way, when the electronic device 10 is impacted by external force in the closing direction, the locking mechanism 300 can bear the force, so that the impact force is collectively absorbed by the shell assembly 100, avoiding the force being directly transmitted to other moving parts to cause large relative movement and damage to the electronic device 10, improving the reliability and stability of the electronic device 10, and improving the impact resistance of the electronic device 10.

[0053] Specifically, the guide plate 200 drives the second shell 120 to slide relative to the first shell 110 along the first direction between the first position and the second position under the action of force, and the locking mechanism 300 locks the first shell 110 and the second shell 120 when the second shell 120 is in the second position, so that the two cannot move relative to each other.

[0054] Specifically, the first guide surface 220 and the second guide surface 230 both extend along the first direction and have a height difference in the second direction perpendicular to the first direction, so that the guide surface 210 is stepped.

[0055] It can be understood that in the present 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.

[0056] It can be understood that after the guide plate 200 abuts against the second shell 120 and moves the second shell 120 relative to the first shell 110 to the second position, the guide plate 200 can abut against the second shell 120 to move the second shell 120 relative to the first shell 110 from the second position to the first position only after the guide plate 200 moves a predetermined stroke relative to the second shell 120. That is, in the process of moving the second shell 120 from the second position to the first position by the guide plate 200, the guide plate 200 moves a stroke relative to the second shell 120, and then can drive the second shell 120 to move. Specifically, the second shell 120 is provided with an opening 121, one end of the guide plate 200 is connected with a stop block 240, the stop block 240 extends into the opening 121 and can abut against two inner walls of the opening 121 along the first direction, so that the guide plate 200 can abut 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 block 240 along the first direction, so that in the process of moving the second shell 120 relative to the first shell 110, the stop block 240 can only abut against one of the two inner walls of the opening 121 along the first direction. In this way, the stroke of the stop block 240 from abutting against one inner wall of the opening 121 along the first direction to abutting against the other inner wall is the predetermined stroke.

[0057] It can be understood that the locking mechanism 300 is abutted against the guide surface 210 in the second direction. During the process that the guide plate 200 drives the second shell 120 to move in the first direction, the contact position of the locking mechanism 300 with the guide surface 210 changes with the movement of the guide plate 200 in the first direction, so as to enable the first guide surface 220 to move to the locking mechanism 300 or the second guide surface 230 to move to the locking mechanism 300. Since the first guide surface 220 and the second guide surface 230 have a height difference 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 can move towards 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, 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 shell 120 in 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 towards the guide surface 210 under the action of elasticity to reset, so as to unlock the second shell 120. In other embodiments, the first guide surface 220 can also protrude from the second guide surface 230, and the locking mechanism 300 can also unlock the second shell 120 when moving away from the guide surface 210 and lock the second shell 120 when moving towards the guide surface 210. Specifically, when moving the second shell 120 from the second position to the first position, the guide plate 200 is first slid relative to the second shell 120 by a certain stroke, and in the process, the locking mechanism 300 is moved from the second guide surface 230 to the first guide surface 220 to unlock the second shell 120, and then the guide plate 200 is abutted against the second shell 120 to drive the second shell 120 to move relative to the first shell 110.

[0058] Specifically, the guide surface 210 comprises a transition guide surface 250, which is connected between the first guide surface 220 and the second guide surface 230 and smoothly connects the first guide surface 220 and the second guide surface 230. By arranging the transition guide surface 250, the locking mechanism 300 can smoothly transition when sliding between the first guide surface 220 and the second guide surface 230. It can be understood that, during the movement of the locking mechanism 300 along the first guide surface 220, the locking mechanism 300 does not move in the second direction because the first guide surface 220 extends in the first direction without 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 height difference. Thus, during the process of the locking mechanism 300 climbing from the first guide surface 220 to the second guide surface 230 through the transition guide surface 250, or falling from the second guide surface 230 to the first guide surface 220 through the transition guide surface 250, the locking mechanism 300 moves in the second direction.

[0059] In the embodiments of the present application, the guide plate 200 is provided with guide surfaces 210 on both sides, and the locking mechanism 300 is two, which are respectively located on both sides of the guide plate 200 and correspond to the two guide surfaces 210. In this way, the two locking mechanisms 300 are respectively arranged on both sides of the guide plate 200 to lock the second shell 120 at two positions, that is, to provide two supporting points for the second shell 120 to bear the force when the second shell 120 is subjected to external force, thereby ensuring the stability of the locking of the electronic device 10.

[0060] The specific structure of the locking mechanism 300 will be introduced below.

[0061] Continuing to refer to Figures 3 to 9In some embodiments, the shell assembly 100 is provided with a limiting member 122. The locking mechanism 300 comprises an abutting assembly 310 and a locking assembly 330 connected with the abutting assembly 310, the abutting assembly 310 abuts against the guide surface 210, and the locking assembly 330 cooperates with the limiting member 122 to lock the shell assembly 100 in the unfolded state. The movement stroke of the abutting assembly 310 is smaller than that of the locking assembly 330. It can be understood 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 assembly 310 in the second direction, and therefore, under the condition of a certain stroke, by increasing the movement stroke of the locking assembly 330 in the second direction and reducing the movement stroke of the abutting assembly 310 in the second direction, the height difference between the first guide surface 220 and the second guide surface 230 is reduced, and the transition of the first guide surface 220 and the second guide surface 230 is relatively smooth, so that the abutting assembly 310 does not receive a large resistance during the climbing process along the guide surface 210 due to the large height difference, and the abutting assembly 310 does not produce an instantaneous drop during the downhill process along the guide surface 210 due to the large height difference, thereby avoiding the problem of abnormal noise, and thus the relative movement of the first shell 110 and the second shell 120 has a good silent effect. Specifically, the limiting member 122 is arranged on the second shell 120, and the locking assembly 330 cooperates with the limiting member 122 to lock the second shell 120 relative to the first shell 110 in the second position.

[0062] In the present application, the locking mechanism 300 comprises a traction rope 350, and the abutting assembly 310 comprises an abutting member 311 abutting against the guide surface 210 and a transmission wheel 312 connected with the abutting member 311. The traction rope 350 is connected with the locking assembly 330 after winding around the transmission wheel 312. Specifically, the first end of the traction rope 350 is fixed relative to the first shell 110, and the second end of the traction rope 350 is connected with the locking assembly 330 after winding around the transmission wheel 312. After the abutting member 311 and the transmission wheel 312 move synchronously in the second direction by a first displacement S1, the second end and the locking assembly 330 connected therewith need to move in the second direction by a second displacement S2, and S2=2S1. Thus, by the cooperation of the transmission wheel 312 and the traction rope 350, the movement stroke of the abutting assembly 310 in the second direction can be smaller than that of the locking assembly 330 in the second direction.

[0063] Further, the locking mechanism 300 comprises a first elastic member 360 and a second elastic member 370, the first elastic member 360 applies a first elastic force F1 to the abutting assembly 310 towards the guide surface 210, and the second elastic member 370 applies a second elastic force F2 to the locking assembly 330 away from the guide surface 210, wherein F1>2F2. It can be understood that, under the elastic action of the first elastic member 360, the abutting assembly 310 has a tendency to move towards the guide surface 210, thereby maintaining abutment with the guide surface 210, while under the elastic action of the second elastic member 370, the locking assembly 330 has a tendency to move away from the guide surface 210, thus, under the cooperation of the first elastic member 360 and the second elastic member 370, the traction rope 350 can be kept taut, thereby realizing linkage between the abutting assembly 310 and the locking assembly 330. In addition, during the movement of the abutting assembly 310 from the second guide surface 230 to the first guide surface 220, the first elastic member 360 elastically acts on the abutting assembly 310, and the abutting assembly 310 needs to overcome the elastic force of the second elastic member 370 before it can be forced to move towards the guide surface 210, therefore, the first elastic force of the first elastic member 360 is greater than twice the second elastic force of the second elastic member 370.

[0064] In combination Figure 7 With Figure 10 As shown, specifically, the abutting assembly 310 comprises a transmission member 313 connected between the abutting member 311 and the transmission wheel 312; the first elastic member 360 elastically acts on the transmission member 313 to elastically abut the abutting member 311 against the guide surface 210. By providing the transmission member 313, the connection between the abutting member 311 and the transmission wheel 312 can be realized, so that they move synchronously. Specifically, the first shell 110 can be fixedly provided with a first guide block 111, the abutting assembly 310 is accommodated inside the first guide block 111, and the first guide block 111 guides the transmission member 313 in the second direction, thereby guiding the entire abutting assembly 310 in the second direction. Specifically, the transmission member 313 can be configured to comprise a guide rod 314 and a connecting portion 315, the connecting portion 315 connects the abutting member 311 and the transmission wheel 312, the first elastic member 360 is sleeved on the guide rod 314 and applies the first elastic force F1 to the connecting portion 315 towards the guide surface 210. Specifically, the first elastic member 360 is a spring, and one end thereof abuts against the first guide block 111 and the other end thereof abuts against the connecting portion 315. In other embodiments, the first elastic member 360 can also be a tension spring, an elastic column or a spring sheet or other types of elastic elements. Specifically, the first guide block 111 can be provided with a guide hole for the guide rod 314 to pass through, or can be provided with a guide chamber accommodating and guiding the connecting portion 315. Specifically, the transmission wheel 312 is a pulley that can rotate relative to the transmission member 313, thereby reducing the wear of the traction rope 350 when moving relative to the transmission wheel 312.

[0065] In the embodiment of the present application, the abutting member 311 can roll relative to the guide surface 210, so that rolling friction is formed between the abutting member 311 and the guide surface 210, reducing the wear of the guide surface 210 by the abutting member 311, and reducing the resistance to the movement of the abutting member 311 along the guide surface 210, so that smooth and silent movement is achieved between the abutting member 311 and the guide plate 200. It should be noted that in other embodiments, the abutting member 311 and the guide surface 210 can also be sliding friction, at which time the abutting member 311 and the guide surface 210 need to be configured as relatively wear-resistant metal pieces. In addition, in order to make the sliding friction resistance between the abutting member 311 and the guide surface 210 smaller, the contact area between the abutting member 311 and the guide surface 210 can be reduced, for example, the abutting member 311 and the guide surface 210 are in point contact or line contact.

[0066] Specifically, since the abutting member 311 and the transmission wheel 312 are connected through the transmission member 313, the abutting member 311 can be configured as a bearing connected with the transmission member 313. For the bearing, it generally has an inner ring and an outer ring, and the inner ring and the outer ring can rotate relative to each other. The inner ring of the bearing is fixedly connected with the transmission member 313, and the outer ring is in rolling contact with the guide surface 210. Specifically, the outer ring of the bearing can be configured of metal material, and can also be of non-metal material, for example, polyformaldehyde (POM). After the abutting member 311 is configured as a bearing, the life of the opening and closing of the electronic device 10 is greatly improved, and the life test of 20W times has been passed.

[0067] In combination with Figure 6 With Figure 8 As shown in FIG. 12, specifically, the limiting member 122 includes a limiting groove 123 formed in the shell assembly 100, and part of the locking assembly 330 extends into the limiting groove 123 under the action of the second elastic member 370 when the shell assembly 100 is in the unfolded state, so as to lock the shell assembly 100. It can be understood that after the locking assembly 330 extends into the limiting groove 123, the second shell 120 and the first shell 110 are locked in the first direction, so that the two cannot move relative to each other, and thus the second shell 120 is maintained in the second position. When the locking assembly 330 is retracted from the limiting groove 123, the second shell 120 and the first shell 110 are unlocked in the first direction.

[0068] In combination with Figures 8 to 10As shown, specifically, the locking assembly 330 includes a clamping block 331 which can be wholly or at least partially inserted into the limiting slot 123. Specifically, the locking assembly 330 includes a guide shaft 332 connected with the clamping block 331, and a second elastic member 370 is sleeved on the guide shaft 332 to realize guiding through the guide shaft 332, and the second elastic member 370 elastically acts on the clamping block 331 to apply a second elastic force F2 of the clamping block 331 away from the guide surface 210. Specifically, the first shell 110 can be fixedly provided with a second guide block 112, and the locking assembly 330 is accommodated inside the second guide block 112, and the second guide block 112 guides the locking assembly 330 in the second direction. Specifically, the second guide block 112 can be provided with a guide hole for the guide shaft 332 to pass through, or can be provided with a guide cavity for accommodating the clamping block 331 and guiding the clamping block 331. Specifically, the second elastic member 370 is a spring, and one end of the second elastic member 370 abuts against the second guide block 112, and the other end of the second elastic member 370 abuts against the clamping block 331. In other embodiments, the second elastic member 370 can also be a tension spring, an elastic column or a spring sheet or other types of elastic elements. In other embodiments, a columnar limiting block can also be arranged on the limiting member 122, and a limiting slot 123 is arranged at the end of the clamping block 331, and the limiting slot 123 is sleeved on the limiting block, so as to realize locking of the second shell 120.

[0069] In the embodiments of the present application, the first shell 110 is provided with a third guide block 113 for guiding the guide plate 200. Specifically, the third guide block 113 includes a first part 114 and a second part 115, and the first part 114 and the second part 115 are respectively located on both sides of the guide plate 200 in the second direction, and a guide groove (not marked in the figure) for accommodating the guide plate 200 is formed between the first part 114 and the second part 115. Specifically, the width of the guide groove is substantially equal to the distance between the two first guide surfaces 220 of the guide plate 200 in the second direction, that is, the narrowest part of the guide plate 200 in the second direction is the region provided with the first guide surface 220, and the widest part of the guide plate 200 in the second direction is the region provided with the second guide surface 230, and the width of the guide groove is exactly matched with the narrowest part of the guide plate 200.

[0070] Further, the first shell 110 is provided with a fourth guide block 116, the fourth guide block 116 limits the guide plate 200 in a direction perpendicular to the first direction and the second direction, the first part 114 and the second part 115 are connected on one side of the guide plate 200, thereby limiting the guide plate 200 on the side away from the fourth guide block 116, thereby forming a gap between the fourth guide block 116 and the third guide block 113 for the guide plate 200 to pass through, thereby guiding the guide plate 200. Specifically, the fourth guide block 116 extends along the second direction, and covers the gap between the guide plate 200 and the first guide block 111, the fourth guide block 116 is connected with the first shell 110, and forms a space with the first shell 110 to accommodate the first guide block 111, and limits the first guide block 111 in the space.

[0071] Specifically, the third guide block 113 is arranged near the locking mechanism 300, the third guide block 113 can guide the movement of the guide plate 200 in the first direction, and ensure the smooth movement of the guide plate 200, in addition, near the third guide block 113, the swing amplitude of the guide plate 200 is weak, thereby the locking mechanism 300 can not produce abnormal sound in the process of relative movement with the guide plate 200, thereby the relative movement process of the first shell 110 and the second shell 120 is better in mute effect.

[0072] In the embodiment of the application, the electronic device 10 further comprises a driving mechanism 400 arranged on the shell assembly 100, the driving mechanism 400 is connected with the guide plate 200 to drive the guide plate 200 to move. In this way, the shell assembly 100 is unfolded or folded under the driving of the guide plate 200. It can be understood that the driving mechanism 400 can be omitted, and the user can directly drive the second shell 120 and the first shell 110 to move by manual or other ways.

[0073] In combination with Figure 2 , Figure 10 and Figure 11As shown, specifically, the driving mechanism 400 includes a driver 410 and a movable member 420 connected with the output end of the driver 410, the driver 410 is connected with the shell assembly 100, and the movable member 420 is connected with the guide plate 200 to drive the guide plate 200 to move. In the embodiment, the driver 410 is installed on the first shell 110, and can be a stepper motor, and the movable member 420 can further include a screw rod (not shown) and a nut (not shown), the stepper motor drives the screw rod to rotate, the screw rod in turn drives the movement through the nut, and in turn drives the guide plate 200 to move along the first direction, and the movement of the guide plate 200 along the first direction drives the second shell 120 to move relative to the first shell 110. Of course, in some embodiments, the movable member 420 can also be a gear reduction mechanism. In other embodiments, the movable member 420 can include a gear and a rack, the driver 410 drives the gear to rotate, the gear drives the rack to move, and the rack is connected with the guide plate 200 to achieve the movement of the second shell 120 relative to the first shell 110.

[0074] Specifically, one guide rail assembly 500 is arranged on each side of the driving mechanism 400, which can assist the movement of the second shell 120 relative to the first shell 110, and avoid the failure of jamming or even locking caused by the different movement of the two sides of the second shell 120.

[0075] In the embodiment, the number of the driving mechanism 400 is not limited, and the driving mechanism 400 can be one, two or more than two, and the number of the guide plate 200 is also not limited. One guide plate 200 corresponds to two locking mechanisms 300, and thus the number of the locking mechanism 300 is not limited, and can be matched with the guide plate 200 to meet different requirements.

[0076] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that it is within the scope of the present application.
