[0047] Please combine Figure 1 , Figure 2 and Figure 3, the electronic device 100 of this embodiment includes a shell assembly 10 and a flexible display screen 20. The shell assembly 10 is a hollow structure, and the flexible display screen 20 is arranged on the shell assembly 10. The electronic device 100 may also include components such as a circuit board (not shown), a battery (not shown), and the circuit board, the battery, etc. may be arranged in the shell assembly 10. The circuit board may integrate the processor, the power management module, the storage unit, and the baseband chip of the electronic device 100. The flexible display screen 20 is communicatively connected to the processor, and the battery can power the flexible display screen 20 and the electronic components on the circuit board. Of course, the electronic device 100 may also include a camera module, which is communicatively connected to the circuit board, and the battery can power the camera module. It is understandable that the electronic device 100 of the embodiment of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices 100. In the embodiment of the present application, a mobile phone is taken as an example for explanation.

[0048] The housing assembly 10 includes a first housing 12 and a second housing 14, and the second housing 14 and the first housing 12 can move relative to each other. 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, so that an end of the second housing 14 away from the first housing 12 and an end of the first housing 12 away from the second housing 14 move toward each other or away from each other.

[0049] Furthermore, the second housing 14 can slide relative to the first housing 12 to a first position and a second position. Figure 4 , Figure 5 and Figure 6 When the second housing 14 is in the first position, the electronic device 100 can obtain a relatively large display area to enhance the user experience of the electronic device 100; Figure 7 and Figure 8 When the second shell 14 is in the second position, the electronic device 100 has a relatively small size and is easy to carry. It is understandable that in the embodiments of the present application, the first position, the second position and similar expressions all refer to the relative position of the second shell 14 and the first shell 12. To simplify the expression, "the second shell 14 is in the first position" or "in the first position" and similar expressions refer to the second shell 14 being in the first position relative to the first shell 12, and "the second shell 14 is in the second position" or "in the second position" and similar expressions refer to the second shell 14 being in the second position relative to the first shell 12.

[0050] In this embodiment, the first position is used as a reference to more clearly determine the position of the end of the second housing 14 away from the first housing 12 and the end of the first housing 12 away from the second housing 14. Figure 4For example, when the second shell 14 is in the first position, the leftmost side in the width direction of the electronic device 100 is the end of the second shell 14 away from the first shell 12, and the rightmost side in the width direction of the electronic device 100 is the end of the first shell 12 away from the second shell 14.

[0051] In some embodiments, 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 screen 20 is variable. In other words, the size of the electronic device 100 in the width direction is variable. In this embodiment, the interface of the electronic device 100, such as a data cable jack, a charging cable jack, or a headphone jack, can be arranged 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 screen 20 is variable. In other words, the size of the electronic device 100 in the length direction is variable. In this embodiment, the interface of the electronic device 100, such as a data cable jack, a charging cable jack, or a headphone jack, can be arranged at the end in the length direction.

[0052] Continue reading Figure 8 , the flexible display screen 20 may include a fixed portion 20a and a free portion 20b that are arranged relatively to each other, and the fixed portion 20a is arranged on the first shell 12 and is relatively fixed to the position of the first shell 12. In the second position, the flexible display screen 20 bypasses the end of the second shell 14 away from the first shell 12, and the free portion 20b of the flexible display screen 20 is accommodated in the shell assembly 10, so that part of the flexible display screen 20 is hidden in the shell assembly 10, and the part of the flexible display screen 20 hidden in the shell assembly 10 may not be used for display. In other words, the movement of the first shell 12 relative to the second shell 14 can make at least part of the free portion 20b unfold in the second shell 14, or make the free portion 20b unfolded in the second shell 14 retract into the shell assembly 10.

[0053] It is understandable that in the embodiments of the present application, the positions of the two objects are relatively fixed, which means that the two objects cannot produce relative movement under normal circumstances. The two objects with relatively fixed positions can be physically directly connected, or indirectly connected through an intermediate structure. Taking the fixing portion 20a and the first shell 12 as an example, the positions of the fixing portion 20a and the first shell 12 are relatively fixed. The fixing portion 20a and the first shell 12 can be directly in contact, such as using threaded fasteners or clamping to achieve direct fixation of the fixing portion 20a and the first shell 12, or the fixing portion 20a can be indirectly fixed to the first shell 12 through structures such as an adhesive layer and an intermediate connecting plate.

[0054] It is understandable that the fixed portion 20a and the free portion 20b can be distinguished in the following manner, referring to Figure 8When the second housing 14 is in the second position relative to the first housing 12, the portion of the flexible display screen 20 exposed outside 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 considered as the free portion 20b. In some embodiments, when the second housing 14 is in the second position, the fixed portion 20a exposed outside the housing assembly 10 is roughly rectangular, and its size can be 5 to 6 inches, which is equivalent to the size of the display area of ​​a general smart phone, so that the electronic device 100 is easy to carry and convenient to use.

[0055] Combined with Figure 3 , the second housing 14 may include a back cover 142 and a baffle 144, the fixed portion is exposed to one side of the baffle 144, and the free portion 20b can enter and exit the second housing 14 from the end of the baffle 144 away from the first housing 12. The back cover 142 is connected to the side of the baffle 144 facing away from the flexible display screen 20, and the back cover 142 covers the free portion 20b of the flexible display screen 20 when in the second position. The back cover 142 may be provided with a light-transmitting area, and the part of the flexible display screen 20 accommodated in the shell assembly 10 in the second position may also be used for display, so that the user can view the information displayed on the flexible display screen 20 from the light-transmitting area, thereby expanding the use scenario of the electronic device 100. For example, in this embodiment, the electronic device 100 does not need to be provided with a front camera, and the rear camera module 40 can be used to realize functions such as selfie and video call. The light-transmitting area can be composed of transparent glass, or it can be formed by the opening of the back cover 142. After the second housing 14 slides relative to the first housing 12 to the first position, at least part of the flexible display screen 20 accommodated in the shell assembly 10 is exposed. The exposed flexible display screen 20 can be used for display, so that the electronic device 100 has a relatively large display area to enhance the user experience.

[0056] Continue reading Figure 3 In some embodiments, the second housing 14 may further include a slide plate 146, which is fixedly connected to the baffle 144, and the baffle 144 is disposed on the periphery of the slide plate 146. Specifically, the slide plate 146 may be fixedly connected to the baffle 144 by means of threaded fasteners, clamping, or welding. The slide plate 146 may improve the structural rigidity of the second housing 14, and the first housing 12 may be slidably matched with the slide plate 146 to improve the stability of the movement of the second housing 14 relative to the first housing 12.

[0057] In some embodiments, a guide arc surface 146a is provided at one end of the slide plate 146 away from the first housing 12, and the free portion 20b of the flexible display screen 20 is attached to the guide arc surface 146a and slidably cooperates with the guide arc surface 146a. In the process of the second housing 14 switching from the second position to the first position relative to the first housing 12, the guide arc surface 146a can guide the flexible display screen 20 to deform and unfold in the second housing 14. The guide arc surface 146a can limit the bending radius of the flexible display screen 20 to an appropriate range to avoid damage to the flexible display screen 20 due to a too small bending radius. Of course, the guide arc surface 146a can also prevent the flexible display screen 20 from having an excessively large bending radius, which may cause the thickness of the electronic device 100 to be too large.

[0058] like Figure 3 As shown, in some embodiments, the surface of the guide arc surface 146a is relatively smooth. In the process of unfolding the flexible display screen 20 to the second shell 14, the guide arc surface 146a can slidably contact the flexible display screen 20 through its smooth surface. In the process of switching the second shell 14 from the second position to the first position, the part of the flexible display screen 20 attached to the guide arc surface 146a is stretched open by the guide arc surface 146a, so that more flexible display screen 20 is exposed to the outside of the shell assembly 10 and is in a flat state. In the process of switching the second shell 14 from the first position to the second position, the flexible display screen 20 can be smoothly retracted into the shell assembly 10 along the guide arc surface 146a, that is, the part of the flexible display screen 20 unfolded in the second shell 14 is smoothly retracted into the shell assembly 10.

[0059] In other embodiments, a roller may be provided at one end of the slide plate 146 away from the first housing 12, the roller may be rotatably provided on the slide plate 146, the roller may be a rotating shaft structure with convex teeth, and the flexible display screen 20 may be linked with the roller by means of engagement or the like. When the second housing 14 slides relative to the first housing 12, the part of the flexible display screen 20 engaged with the roller is driven by the roller to move and unfold or retract into the housing assembly 10.

[0060] Of course, the roller can also be a round shaft without teeth. In this embodiment, the roller is rotatably disposed on the slide plate 146. During the process of gradually unfolding the flexible display screen 20, the roller can rotate with the movement of the flexible display screen 20 to reduce the resistance encountered by the flexible display screen 20 during the unfolding process and reduce the wear of the contact portion between the roller and the flexible display screen 20.

[0061] It can be understood that, in this embodiment, the first position and the second position can be regarded as two extreme positions of the second shell 14 moving relative to the first shell 12. In the first position, the display area of ​​the flexible display screen 20 reaches the maximum state. Under normal circumstances, the second shell 14 can no longer move relatively away from the first shell 12. In the second position, the display area of ​​the flexible display screen 20 reaches the minimum state. Under normal circumstances, the second shell 14 can no longer move towards the first shell 12. The first position and the second position can be achieved by setting a limiting structure. For example, one of the first shell 12 and the second shell 14 can be provided with a spring sheet, and the other can be provided with a slot. In the first position and the second position, the spring sheet is engaged with the slot to fix the positions of the first shell 12 and the second shell 14 relatively.

[0062] It is understandable that multiple intermediate positions can be set between the first position and the second position to achieve the positioning of the second housing 14 relative to the first housing 12 at multiple intermediate positions, and enable the flexible display screen 20 to have different display areas at different intermediate positions, thereby expanding the use scenarios of the electronic device 100. Multiple intermediate positions can also be implemented using a limiting structure.

[0063] refer to Fig. 9 and Fig.10 One of the first shell 12 and the second shell 14 is provided with a guide rail 101, and the other is provided with a slide groove 103. The guide rail 101 includes a base 1011 and an anti-detachment portion 1013 connected to the end of the base 1011. The anti-detachment portion 1013 is provided on opposite sides of the base 1011. The anti-detachment portion 1013 is slidably matched with the slide groove 103, so that the second shell 14 can slide relative to the second shell 14, and drive the flexible display screen 20 to enter and exit the shell assembly 10.

[0064] In some embodiments, the guide rails 101 are located on opposite sides of the first housing 12, and the guide rails 101 extend along the moving direction of the second housing 14 relative to the first housing 12. The first housing 12 may include a frame 121 for mounting and carrying components such as circuit boards and batteries, and the base 1011 and the frame 121 may be integrally formed to facilitate the processing and forming of the guide rails 101. One end of the flexible display screen 20 is relatively fixed to the frame 121.

[0065] Of course, in other embodiments, the guide rail 101 can also be assembled with the frame 121. For example, the guide rail 101 and the frame 121 can be processed separately, and then the guide rail 101 and the frame 121 are fixedly connected by threaded fasteners, welding, or bonding. In this embodiment, the frame 121 can be made of a relatively lightweight material such as aluminum alloy, and the guide rail 101 can be made of a wear-resistant material such as stainless steel.

[0066] Further, the second shell 14 includes a wear-resistant part 148, which is connected to the baffle 144 and fixedly connected to the baffle 144, and the wear-resistant part 148 has a slide groove 103. In the embodiment where the second shell 14 includes a slide plate 146, the wear-resistant part 148 and the guide rail 101 are provided at opposite ends of the slide plate 146 in a direction perpendicular to the sliding direction of the second shell 14 relative to the first shell 12. The wear-resistant part 148 can be made of materials such as polyoxymethylene (POM) to improve the wear resistance of the wear-resistant part 148 and ensure the lightweight design of the second shell 14.

[0067] In some embodiments, the cross section of the guide rail 101 is roughly T-shaped, and the cross section of the slide groove 103 is also roughly T-shaped. In the direction perpendicular to the sliding direction of the second housing 14 relative to the first housing 12, the slide groove 103 includes a notch 103a and a limiting groove 103b connected to the notch 103a. The width of the limiting groove 103b is greater than the width of the notch 103a, the base 1011 is inserted into the notch 103a, and the anti-slip portion 1013 is slidably matched with the limiting groove 103b. In this embodiment, since the width of the limiting groove 103b is greater than the width of the notch 103a, the anti-slip portion 1013 slides in the limiting groove 103b, and the side of the anti-slip portion 1013 facing the frame 121 can abut against the groove wall of the limiting groove 103b to provide a supporting force from the outside of the electronic device 100 to the frame 121, thereby preventing the wear-resistant part 148 and the baffle 144 from expanding and deforming outward and causing eversion during the sliding of the second shell 14 relative to the first shell 12, thereby maintaining the appearance refinement of the electronic device 100 and the structural strength of the entire machine.

[0068] It is understandable that the T-shaped guide rail 101 can save the material cost of the guide rail 101 while ensuring the structural strength of the guide rail 101, and reduce the space occupied by the guide rail 101 in the electronic device 100, so that the internal structural layout of the electronic device 100 is more compact and the electronic device 100 can be designed to be lightweight.

[0069] Of course, in other embodiments, the cross section of the guide rail 101 may also be in other shapes. For example, the cross section of the guide rail 101 may be in an inverted triangle or other shapes.

[0070] In the above-mentioned electronic device 100, one of the first shell 12 and the second shell 14 is provided with a guide rail 101, and the other is provided with a slide groove 103. The guide rail 101 includes a base 1011 and an anti-slip portion 1013 connected to the end of the base 1011, and the anti-slip portions 1013 are provided on opposite sides of the base 1011. The anti-slip portions 1013 are slidably matched with the slide groove 103, so that the second shell 14 can slide relative to the second shell 14 and drive the flexible display screen 20 in and out of the shell assembly 10. The matching structure of the anti-slip portion 1013 and the slide groove 103 can prevent the guide rail 101 from escaping from the slide groove 103, thereby preventing the slide groove 103 from expanding and deforming outward, so as to maintain the appearance and performance of the electronic device 100.

[0071] Continue to refer Fig.10 In some embodiments, a receiving groove 144a may be provided on one side of the baffle 144 facing the guide rail 101, and the wear-resistant member 148 may be received in the receiving groove 144a. The wear-resistant member 148 may be bonded or interference-fitted with the baffle 144. The provision of the receiving groove 144a can not only protect the wear-resistant member 148 in the circumferential direction by the baffle 144, but also prevent the thickness of the wear-resistant member 148 from being directly superimposed on the thickness of the baffle 144, thereby saving material costs and making the internal structure layout of the electronic device 100 more compact, so as to realize a lightweight design of the electronic device 100.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
