Referring to fig. 1 and 2, an electronic device 100 of the present embodiment includes a housing assembly 10 and a flexible display 20. The case assembly 10 is a hollow structure, and the flexible display 20 is disposed at the case assembly 10. Electronic device 100 may also include a circuit board (not shown) and a battery (not shown), both of which may be disposed to case 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 processor, 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, the camera module is connected to the circuit board in communication, and the battery can supply power to the camera module. 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 and 4, the housing assembly 10 includes a first housing 12 and a second housing 14, the second housing 14 and the first housing 12 being capable of relative movement. Specifically, in the present embodiment, the second housing 14 and the first housing 12 are slidably connected. In other words, the second housing 14 can slide relative to the first housing 12 and bring the flexible display screen 20 into and out of the housing assembly 10. 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 first housing 12 away from the second housing 14 and the end of the second housing 14 away from the first housing 12 move toward or away from each other.

The second housing 14 is slidable relative to the first housing 12 to a first position and a second position. With reference to fig. 2, when the second housing 14 is in the first position, the electronic device 100 is in an unfolded state, which has a relatively large display area, so that the use experience of the electronic device 100 can be improved; referring to fig. 1, when the second housing 14 is in the second position, the electronic device 100 is in a folded state, and has a relatively small external size for carrying. It is understood that in the embodiments described later in this application, the first position, the second position and the like refer to the relative positions of the first housing 12 and the second housing 14. For simplicity, similar expressions that "the second housing 14 is located at the first position" or "in the first position" refer to the second housing 14 being in the first position relative to the first housing 12, that is, the electronic device 100 being in the unfolded state; the expression "the second housing 14 is located at the second position" or "in the second position" means that the second housing 14 is located at the second position relative to the first housing 12, that is, the electronic device 100 is in the folded state.

In the embodiment of the present application, with the first position as a reference, the position of the end of the first casing 12 away from the second casing 14 and the position of the end of the second casing 14 away from the first casing 12 can be determined more clearly. Taking fig. 2 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 that in the second position, so that the width dimension of the exposed flexible display 20 is variable. In other words, the electronic apparatus 100 may vary in size in the width direction. In such an embodiment, an external 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 of 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 external 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. 5 and 6, the flexible display 20 may include a fixed portion 20a and a free portion 20b, where the fixed portion 20a is disposed on the first casing 12 and fixed relative to the first casing 12, and in the second position, the flexible display 20 bypasses an end of the second casing 14 away from the first casing 12, and the free portion 20b of the flexible display 20 is accommodated in the shell assembly 10, so that a portion of the flexible display 20 is hidden in the shell assembly 10, and a portion of the flexible display 20 hidden in the shell assembly 10 may not be used for displaying.

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, that is, when the electronic device 100 is in the folded state, the portion of the flexible display screen 20 exposed out of the housing assembly 10 is the fixed portion 20a of the flexible display screen 20, and the portion of the flexible display screen 20 accommodated in the housing assembly 10 is the free portion 20 b.

Further, the second housing 14 may include a rear cover (not shown) that covers the free portion 20b of the flexible display 20 when in the second position. The rear cover may have a light-transmitting area, and the portion of the flexible display screen 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 screen 20 from the light-transmitting area, and further expand 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 a rear camera module without providing a front camera. The light-transmitting area can be formed by transparent glass or an opening of the rear cover. After the first housing 12 is slid to a first position relative to the second housing 14, 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.

In some embodiments, the electronic device 100 may include a guide (not shown) that may be disposed at an end of the second housing 14 away from the first housing 12, and the guide may guide the flexible display 20 to deform and unfold from the second housing 14 during switching of the second housing 14 from the second position to the first position relative to the first housing 12. The guide may limit the bending radius of the flexible display 20 within a suitable range to avoid damage to the flexible display 20 due to too small a bending radius. Of course, the guide member can also prevent the flexible display screen 20 from having an excessively large bending radius, which results in an excessively large thickness of the electronic device 100. In some embodiments, the guide may be a shaft structure with a convex tooth, and the flexible display 20 is coupled to the guide by meshing or the like. When the first housing 12 slides relative to the second housing 14, the guide member moves the portion of the flexible display screen 20 engaged with the guide member and extends or retracts into the case assembly 10.

It will be appreciated that in other embodiments, the guide may also be a circular shaft without teeth. During the process of switching the first housing 12 from the second position to the first position, the portion of the flexible display screen 20 attached to the guide member is spread by the guide member, so that more flexible display screen 20 is exposed outside the case assembly 10 and is in a flat state. In this embodiment, the guide member is rotatably disposed on the second housing 14, and the guide member can rotate along with the movement of the flexible display 20 during the gradual unfolding of the flexible display 20, so as to reduce the resistance to the flexible display 20 during the unfolding process and reduce the wear of the guide member.

During the process of switching the first housing 12 from the first position to the second position, the flexible display 20 can be retracted by the guiding member, i.e. the portion of the flexible display 20 that is deployed in the second housing 14 is retracted into the case assembly 10. In some embodiments, the electronic device 100 may further include a driving mechanism, which may be disposed in the case assembly 10, and the driving mechanism may be linked with the second housing 14 or the first housing 12 to drive the second housing 14 to slide relative to the first housing 12, so as to drive the flexible display 20 to be extended or retracted.

Referring to fig. 6, in other embodiments, the guides may be absent, and the end of the second housing 14 remote from the first housing may be machined to a cylindrical surface, which may have a relatively small surface roughness. The smooth cylindrical surface is in slidable contact with the flexible display 20 during the process of unfolding and folding the flexible display 20 to guide the unfolding and folding of the flexible display.

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 away from the first housing 12. In the second position, the display area of the flexible display 20 is at a minimum, and under normal conditions, the second housing 14 can not move toward the first housing 12. The first and second positions may be achieved by providing a stop structure on the first housing 12 or the second housing 14 or the guide. For example, the first housing 12 may be provided with a spring, the second housing 14 may be provided with two slots, and when the first position is reached, the spring is engaged with one of the slots, so as to position the first housing 12 and the second housing 14 at the first position; when the first housing 12 and the second housing 14 are located at the first position, the elastic piece is engaged with the other engaging groove.

It is understood that a plurality of intermediate positions may be disposed between the first position and the second position to achieve the positioning of the first housing 12 relative to the second housing 14 at a plurality of 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 plurality of intermediate positions may also be implemented by using a limiting structure, for example, the second housing 14 may be positioned at the plurality of intermediate positions relative to the first housing 12 by matching the elastic piece with the slot.

Referring to fig. 4, 5 and 6, the first housing 12 may include a frame 121 and a support plate 123 connected to the frame 121, wherein the frame 121 is disposed on an outer periphery of the fixing portion 20a of the flexible display 20. The carrier plate 123 may be integrally formed with the frame 121, or may be assembled with the frame 121. The electronic device 100 may further include a supporting frame 30, and one end of the supporting frame 30 is connected to the first housing 12 and stacked on the supporting plate 123, for example, the supporting frame 30 may be connected to the supporting plate 123 or connected to the frame 121. The opposite end of the support bracket 30 is connected to the second housing 14, and the flexible display screen 20 covers the support bracket 30 stacked on the carrier plate 123. During the process of moving the second housing 14 relative to the first housing 12, the supporting frame 30 is driven to move telescopically.

Referring to fig. 7 and 8, in some embodiments, one end of the supporting frame 30 is connected to an end of the first housing 12 away from the second housing 14 and extends toward the second housing 14 to protrude out of the supporting plate 123. During the movement of the second housing 14 relative to the first housing 12, the end of the support frame 30 connected to the first housing 12 may not move in a translational manner, i.e., during the movement of the second housing 14 relative to the first housing 12, the support frame 30 is elongated, but the overlapping width with the carrier plate 123 of the first housing 12 is constant, i.e., the length of the support frame 30 across the carrier plate 123 is constant. In other embodiments, the end of the supporting frame 30 connected to the first housing 12 may also be spaced apart from the end of the first housing 12 away from the second housing 14, and during the process of moving the second housing 14 relative to the first housing 12, the end of the supporting frame 30 connected to the first housing 12 may not perform a translational motion, so as to maintain the overlapping width with the carrier plate 123.

Further, the support bracket 30 may include opposing first and second ends 31, 32, with the first end 31 being attached to the first housing 12. For example, the first end 31 may be connected to an end of the first housing 12 away from the second housing 14, and the first end 31 may be spaced apart from an end of the first housing 12 away from the second housing 14. The second housing 14 may be formed with a limiting groove 14a, the second end 32 is connected to the second housing 14, and during the process of switching the electronic device 100 between the unfolded state and the folded state, at least a part of the supporting frame 30 between the first end 31 and the second end 32 moves in the limiting groove 14 a. Due to the arrangement of the limiting groove 14a, and at least a part of the supporting frame 30 between the first end 31 and the second end 32 moves in the limiting groove 14a, the limiting groove 14a can increase the contact width between the supporting frame 30 and the second shell 14, that is, the overlapping width between the supporting frame 30 and the second shell 14 is increased, so that the stability of the telescopic movement of the supporting frame 30 is improved.

In the related art, a comb-type slide rail structure is generally adopted to realize the stable sliding of the second housing 14 relative to the first housing 12 and enable the free portion 20b to flatly support and expand to the outside of the second housing 14, that is, one of the first housing 12 and the second housing 14 is provided with a plurality of spaced slide grooves, and the other is provided with a plurality of spaced slide rails, and the slide rails penetrate through the slide grooves in a one-to-one correspondence manner and are in sliding fit with the slide grooves. Due to the structural arrangement, when the second housing 14 and the first housing 12 move away from each other relatively, one end of the second housing 14, which is away from the first housing 12, gradually moves away from the first housing 12, the slide rail also moves in the direction away from the first housing 12, and the length of the slide rail in the slide groove is gradually reduced, that is, the overlapping width of the second housing 14 and the first housing 12 is gradually reduced. When the electronic device 100 is in the unfolded state, the overlapping width of the second housing 14 and the first housing 12 reaches a minimum value, and the strength of the first housing 12 to the supporting structure of the second housing 14 also reaches a minimum value accordingly. In this state, when the electronic device 100 is accidentally dropped or twisted, the supporting structure of the second housing 14 by the first housing 12 is easily damaged.

In the embodiment of the present application, the first housing 12 includes a frame 121 and a support plate 123 connected to the frame 121, one end of the support frame 30 is connected to the first housing 12 and is stacked on the support plate 123, the other opposite end of the support frame 30 is connected to the second housing 14, when the electronic device 100 is in the unfolded state, because the support frame 30 and the first housing 12 maintain a sufficient overlapping width, the strength of the support structure of the second housing 14 by the first housing 12 can be ensured by using the connection of the support frame 30 with the first housing 12 and the second housing 14, and the electronic device 100 is prevented from being damaged when accidentally falling or twisting.

Of course, during the process of moving the second casing 14 relative to the first casing 12 to switch the electronic device 100 between the unfolded state and the folded state, the supporting frame 30 stacked on the supporting plate 123 may also make the second casing 14 and the first casing 12 have a sufficient overlapping width to disperse the force applied by the second casing 14 to the first casing 12, so as to prevent the electronic device 100 from being damaged when the electronic device is accidentally dropped or twisted.

Referring to fig. 4, the supporting frame 30 may include a plurality of parallelogram mechanisms 35 connected in sequence, two adjacent parallelogram mechanisms 35 may be connected by a pin, and the center lines of the plurality of parallelogram mechanisms 35 may be substantially located in a straight line, so as to achieve telescopic deformation during the movement of the second housing 14 relative to the first housing 12. Specifically, the number of the parallelogram mechanisms 35 may be 3 or more, and the larger the number of the parallelogram mechanisms 35, the smaller the deformation space required in the direction perpendicular to the direction in which the second housing 14 moves relative to the first housing 12, and the more compact the internal structure of the electronic apparatus 100 may be.

Further, a plurality of supporting frames 30 may be arranged at intervals along a direction perpendicular to the moving direction of the first casing 12 relative to the second casing 14, for example, the number of the supporting frames 30 may be set to be more than 3. More support frames 30 form more joints with the second housing 14 and more joints with more first housings 12, and this arrangement allows more force points to be obtained for the support frames 30, which can improve the strength of the support structure of the first housing 12 to the second housing 14 and improve the smoothness of the movement of the second housing 14 relative to the first housing 12.

Further, the first housing 12 includes a supporting plate 125 connected to the frame 121, at least a portion of the supporting frame 30 is disposed between the supporting plate 125 and the supporting plate 123, and in the unfolded state, the supporting frame 30 extends from between the supporting plate 123 and the supporting plate 125 to the direction of the second housing 14. The fixing portion 20a of the flexible display 20 is attached to the supporting plate 125 at a side facing away from the supporting frame 30 and connected to the first casing 12. In the process of switching the electronic device 100 between the unfolded state and the folded state, the relative position between the fixing portion 20a and the supporting plate 125 is fixed, and the supporting plate 125 may have a flat plate shape to smoothly and reliably support the fixing portion 20 a. The supporting bracket 30 may be extended from between the supporting plate 125 and the carrier plate 123 or retracted into between the supporting plate 125 and the carrier plate 123 during the movement of the second housing 14 relative to the first housing 12. The structural arrangement can limit the stretching deformation of the supporting frame 30 by using the supporting plate 123 and the supporting plate 125, and the supporting plate 125 and the supporting plate 123 can also limit the stretching deformation of the supporting frame 30 in the thickness direction of the electronic device 100, so as to prevent the supporting frame 30 from being easily distorted in the moving process of the second housing 14 relative to the first housing 12.

In some embodiments, the supporting plate 125 can be provided with a plurality of sliding slots arranged at intervals, the second housing 14 includes an outer frame and a plurality of extending arms arranged at intervals and connected to the outer frame, and the plurality of extending arms are arranged in the sliding slots in a one-to-one correspondence and in a slidable manner. In such an embodiment, the arrangement of the extension arm of the second housing 14 slidably engaged with the sliding slot of the support plate 125 can improve the smoothness of the relative movement between the second housing 14 and the first housing 12.

In some embodiments, the thickness of the free portion 20b of the flexible display 20 may be equal to the sum of the thickness of the fixed portion 20a and the thickness of the support plate 125. After the free portion 20b of the flexible display 20 extends out of the housing assembly 10, the free portion 20b is overlapped on the supporting frame 30, and since the thickness of the free portion 20b is equal to the sum of the thickness of the fixing portion 20a and the thickness of the supporting plate 125, the free portion 20b extending out of the housing assembly 10 and the side of the fixing portion 20a facing away from the supporting frame 30 can be kept flush, i.e. the free portion 20b extending out of the housing assembly 10 and the fixing portion 20a are spread out of the housing assembly 10 flatly, thereby facilitating the use of the user. Of course, it is understood that the above-mentioned structure can also support the free portion 20b of the protruding housing assembly 10 by the supporting frame 30, so that the free portion 20b is effectively supported and the touch operation of the user is facilitated.

In some embodiments, the support frame 30 may include a frame body 37 and rolling bodies (not shown), the frame body 37 constituting a plurality of parallelogram mechanisms 35 and serving to provide structural rigidity. The rolling elements may be balls or rollers, which are rollably provided to the frame body 37. During the switching process of the electronic device 100 between the folded state and the unfolded state, the rolling elements are configured to roll relative to the support plate 123 or the support plate 125, so as to reduce the motion resistance between the frame 37 and the support plate 123 or the support plate 125, and further reduce the resistance when the second housing 14 moves relative to the first housing 12.

In some embodiments, the frame body 37 of the supporting frame 30 may be made of a material with high strength, such as stainless steel, so that the supporting frame 30 has high structural strength and can achieve a thin and compact design, and further, the overall thickness of the electronic device 100 is reduced to achieve a thin design of the electronic device 100.

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

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent application shall be subject to the appended claims.
