[0025] like Figures 1 to 11 As shown, the electronic device includes: a first shell 10 , a second shell 20 , a decorative component 30 and a flexible screen group 40 .

[0026] The first shell 10 is hinged to the second shell 20 so that the electronic device can switch between a folded state and an unfolded state; a decorative piece 30 is provided on the edge of the first shell 10 away from the second shell 20 and the edge of the second shell 20 away from the first shell 10, and a step structure 301 is provided on the outer surface of the decorative piece 30, the step structure 301 has a parallel first surface 302 and a second surface 303, the first surface 302 is away from the first shell 10, and the second surface 303 is close to the first shell 10, and the first surface 302 and the second surface 303 are not blocked; the flexible screen group 40 includes a protective layer 41 and a display layer 42 which are stacked and interconnected, the edge of the protective layer 41 is connected to the first surface 302, the edge of the display layer 42 is in contact with the second surface 303, and the display layer 42 is movable relative to the second surface 303; when the electronic device switches between a folded state and an unfolded state, the distance between the edge of the display layer 42 and the step structure 301 changes.

[0027] In the embodiment of the present application, since the first shell 10 and the second shell 20 are hinged, the electronic device can be switched between the folded state and the unfolded state by applying force to the first shell 10 and / or the second shell 20. Since the edge of the first shell 10 away from the second shell 20 and the edge of the second shell 20 away from the first shell 10 are both provided with decorative elements 30, the decorative elements 30 can decorate the first shell 10 and the second shell 20, thereby improving the aesthetics of the electronic device. Since the outer surface of the decorative piece 30 is provided with a step structure 301, the step structure 301 has a parallel first surface 302 and a second surface 303, the edge of the protective layer 41 is connected to the first surface 302, the edge of the display layer 42 is in contact with the second surface 303, and the display layer 42 is movable relative to the second surface 303. Therefore, when force is applied to the first shell 10 and / or the second shell 20 to switch the electronic device between the folded state and the unfolded state, the distance between the edge of the display layer 42 and the step structure 301 will change, and when the electronic device is in the unfolded state, the edge of the display layer 42 is close to the step structure 301, and the first surface 302 and the second surface 303 are not blocked, so that the display layer 42 is not blocked at all, thereby improving the screen-to-body ratio of the display screen. That is, in the embodiment of the present application, a step structure 301 is provided on the surface of the decorative member 30 facing away from the first shell 10 and the second shell 20, and the edge of the protective layer 41 is connected to the first surface 302, and the edge of the display layer 42 is in contact with the second surface 303, so that when the electronic device switches between the folded state and the unfolded state, the distance between the display layer 42 and the step structure 301 changes, and when the electronic device is in the unfolded state, even if the display layer 42 is close to the step structure 301, the display layer 42 is not blocked by any components. In addition, the width of the decorative member 30 does not need to be increased, so that the display area of ​​the electronic device can be increased and the screen-to-body ratio of the electronic device can be improved.

[0028] It should be noted that in the embodiment of the present application, when the electronic device is in the folded state, the distance between the edge of the display layer 42 and the step structure 301 is the first distance, and when the electronic device is in the unfolded state, the distance between the edge of the display layer 42 and the step structure 301 is the second distance, and the first distance is greater than the second distance. That is, when the electronic device is in the folded state, the edge of the display layer 42 is away from the step structure 301, that is, the edge of the display layer 42 is away from the decorative element 30, and when the electronic device is in the unfolded state, the edge of the display layer 42 is close to the step structure 301, that is, the edge of the display layer 42 is close to the decorative element 30.

[0029] In the related art, the electronic device includes a first shell 10, a second shell 20 and a flexible screen group 40. Along the circumferential direction of the electronic device, the decorative member 30 is simultaneously arranged at the edge of the first shell 10 and the edge of the second shell 20. There is a gap between the decorative member 30 and the first shell 10, and there is a gap between the decorative member 30 and the second shell 20. The protective layer 41 of the flexible screen group 40 is bonded to the surface of the decorative member 30 facing the first shell 10 and the surface of the decorative member 30 facing the second shell 20. The display layer 42 of the flexible screen group 40 is connected to the protective layer 41, and the display layer 42 is movable relative to the protective layer 41. When the electronic device is in a folded state, part of the edge of the display layer 42 is blocked by the decorative member 30, and when the electronic device is in an unfolded state, part of the edge of the display layer 42 is further blocked by the decorative member 30. In addition, in the related art, in order to make the protective layer 41 firmly bonded to the decorative member 30, the width of the decorative member 30 needs to be increased. That is, in the related art, when the electronic device is in the unfolded state, the edge of the display layer 42 is blocked, resulting in the content displayed on the edge of the display layer 42 being blocked, and the width of the decorative member 30 is large, resulting in a reduced screen-to-body ratio of the electronic device. In the embodiment of the present application, by setting a step structure 301 on the surface of the decorative member 30 away from the first shell 10 and the second shell 20, the edge of the protective layer 41 is connected to the first surface 302 of the step structure 301, and the edge of the display layer 42 is connected to the second surface 303 of the step structure 301, so that when the electronic device is in the unfolded state, the edge of the display layer 42 is close to the step structure 301, that is, the edge of the display layer 42 is close to the decorative member 30, but the edge of the display layer 42 is not blocked, and the content displayed on the edge of the display layer 42 can also be used to see, so that under the premise of the same size of the flexible screen group 40, the flexible screen group 40 of the electronic device provided in the embodiment of the present application displays more content, and the width of the decorative member 30 does not need to be increased, so that the screen-to-body ratio of the electronic device provided in the embodiment of the present application is improved. That is, in the embodiment of the present application, by changing the structure of the decorative member 30, the screen-to-body ratio of the electronic device is improved.

[0030] In addition, in the embodiment of the present application, the edge of the protective layer 41 can be bonded to the first surface 302 by an adhesive, which is equivalent to fixing the edge of the protective layer 41, so that when the electronic device switches between a folded state and an unfolded state, the display layer 42 can move relative to the decorative part 30, and then the distance between the edge of the display layer 42 and the decorative part 30 changes.

[0031] In addition, in some embodiments, Fig.10 As shown, both the first shell 10 and the second shell 20 may be provided with a mounting groove 001 , the decorative element 30 is installed in the mounting groove 001 , and the second surface 303 is flush with the first shell 10 and the second shell 20 .

[0032] By providing the mounting groove 001 on the first shell 10 and the second shell 20, when the decorative member 30 is mounted on the first shell 10 and the second shell 20, the decorative member 30 can be directly mounted in the mounting groove 001, so that the decorative member 30 can be easily mounted on the first shell 10 and the second shell 20. In addition, the second surface 303 is flush with the first shell 10 and the second shell 20, so that when the display layer 42 moves relative to the decorative member 30, that is, when the electronic device switches between the folded state and the unfolded state, the display layer 42 can move more conveniently on the second surface 303, avoiding the problem that the second surface 303 is not flush with the first shell 10 during the movement of the display layer 42, which makes it difficult to move the edge of the display layer 42, and avoiding the problem that the second surface 303 is not flush with the first shell 10, which makes it difficult to move the edge of the display layer 42.

[0033] It should be noted that the mounting groove 001 on the first shell 10 can be arranged along the circumferential direction of the first shell 10 , and the mounting groove 001 on the second shell 20 can be arranged along the circumferential direction of the second shell 20 .

[0034] In addition, in some embodiments, Fig. 9 As shown, the flexible screen group 40 can have a first part 401, a second part 402 and a third part 403; the first part 401 is opposite to the first shell 10, the connection between the first shell 10 and the second shell 20 is opposite to the second part 402, and the third part 403 is opposite to the second shell 20; the thickness of the protective layer 41 located in the second part 402 is less than the thickness of the protective layer 41 located in the first part 401, and the thickness of the protective layer 41 located in the second part 402 is less than the thickness of the protective layer 41 located in the third part 403.

[0035] Since the first part 401 of the flexible screen group 40 is opposite to the first shell 10, the connection between the first shell 10 and the second shell 20 is opposite to the second part 402, and the third part 403 is opposite to the second shell 20, when force is applied to the first shell 10 and / or the second shell 20 to make the flexible screen group 40 bend, the flexible second part 402 will be folded, so that the second part 402 of the flexible screen group 40 will be subjected to bending stress. Since the thickness of the protective layer 41 located in the second part 402 is less than the thickness of the protective layer 41 located in the first part 401, and the thickness of the protective layer 41 located in the second part 402 is less than the thickness of the protective layer 41 located in the third part 403, it is equivalent to thinning the second part 402 of the flexible screen group 40, so that when the electronic device switches between the folded state and the unfolded state, the stress distribution gradient on the flexible screen group 40 is reduced, and finally when the electronic device is in the folded state, the bending stress of the second part 402 of the flexible screen group 40 is reduced, so that the service life of the flexible screen group 40 is extended.

[0036] It should be noted that the protective layer 41 and the display layer 42 are bonded together by an adhesive layer. Therefore, in the embodiment of the present application, when the protective layer 41 of the second part 402 of the flexible screen group 40 is thinned, the risk of delamination and failure of the adhesive layer when the flexible screen group 40 is folded can be effectively reduced.

[0037] In addition, in the embodiment of the present application, a first groove may be provided on the surface of the protective layer 41 located in the second part 402 facing the display layer 42, so that the thickness of the protective layer 41 located in the second part 402 is less than the thickness of the protective layer 41 located in the first part 401; the first groove is filled with optical glue, and the optical glue is in contact with the display layer 42.

[0038] By setting a first groove on the surface of the protective layer 41 located in the second part 402 facing the display layer 42, it is equivalent to removing a part of the protective layer 41 located in the second part 402, so that the thickness of the protective layer 41 located in the second part 402 is reduced, and then the second part 402 of the flexible screen group 40 is thinned. In addition, the first groove is filled with optical glue, and the optical glue is in contact with the display layer 42, so that when the electronic device is in the unfolded state, the optical glue can effectively support the protective layer 41, so that the flexible screen group 40 is relatively flat, and avoid the problem that the protective layer 41 may be sunken when the electronic device is in the unfolded state, causing the flexible screen group 40 to be uneven.

[0039] In addition, the first groove of the second part 402 of the flexible screen group 40 is filled with optical glue, which has a low elastic modulus and easy shear slip deformation characteristics, and can reduce the distribution of stress gradients of the flexible screen group 40. In addition, the optical glue is usually a non-Newtonian fluid, which itself has a strong internal friction damping property, so when the second part 402 of the flexible screen group 40 is impacted, the optical glue in the first groove can also effectively absorb the impact kinetic energy, thereby reducing the risk of failure of the flexible screen group 40.

[0040] In addition, in some embodiments, Fig. 9 As shown, the first part 401 has a first bending portion 4011, the third part 403 has a second bending portion 4021, and the first bending portion 4011 and the second part 402 are both spaced apart from the second part 402; the thickness of the protective layer 41 located at the first bending portion 4011 is smaller than the thickness of the protective layer 41 located in the first part 401 except the first bending portion 4011, and the thickness of the protective layer 41 located at the second bending portion 4021 is smaller than the thickness of the protective layer 41 located in the third part 403 except the second bending portion 4021.

[0041] When the electronic device is switched between a folded state and an unfolded state, the first bending portion 4011 and the second bending portion 4021 will also be slightly bent and thus be subjected to bending stress. In the embodiment of the present application, by setting the thickness of the protective layer 41 located at the first bending portion 4011 to be smaller than the thickness of the protective layer 41 located in the first part 401 except the first bending portion 4011, and the thickness of the protective layer 41 located at the second bending portion 4021 to be smaller than the thickness of the protective layer 41 located in the third part 403 except the second bending portion 4021, when the electronic device is switched between a folded state and an unfolded state, the bending stress borne by the first bending portion 4011 and the second bending portion 4021 is reduced, so that the stress distribution gradient of the flexible screen group 40 is reduced, and finally when the electronic device is in the folded state, the bending stress borne by the first bending portion 4011 and the second bending portion 4021 of the flexible screen group 40 is reduced, so that the service life of the flexible screen group 40 is extended.

[0042] In addition, in some embodiments, a second groove is provided on the surface of the protective layer 41 located at the first bending portion 4011 facing the display layer 42, so that the thickness of the protective layer 41 located at the first bending portion 4011 is smaller than the thickness of the protective layer 41 located in the first part 401 except the first bending portion 4011, the second groove is filled with optical glue, and the optical glue is in contact with the display layer 42; a third groove is provided on the surface of the protective layer 41 located at the second bending portion 4021 facing the display layer 42, so that the thickness of the protective layer 41 located at the second bending portion 4021 is smaller than the thickness of the protective layer 41 located in the third part 403 except the second bending portion 4021, the third groove is filled with optical glue, and the optical glue is in contact with the display layer 42.

[0043] By setting a second groove on the surface of the protective layer 41 at the first bending portion 4011 facing the display layer 42, it is equivalent to removing a part of the protective layer 41 at the first bending portion 4011, so that the thickness of the protective layer 41 at the first bending portion 4011 is reduced, and then the first bending portion 4011 of the flexible screen group 40 is thinned. In addition, the second groove is filled with optical glue, and the optical glue is in contact with the display layer 42, so that it can be ensured that when the electronic device is in the unfolded state, the optical glue can effectively support the protective layer 41, so that the flexible screen group 40 is relatively flat, and the problem of the protective layer 41 being concave and causing the flexible screen group 40 to be uneven when the electronic device is in the unfolded state is avoided. Similarly, by setting a third groove on the surface of the protective layer 41 at the second bending portion facing the display layer 42, it is equivalent to removing a part of the protective layer 41 at the second bending portion 4021, so that the thickness of the protective layer 41 at the second bending portion 4021 is reduced, and then the first bending portion 4011 of the flexible screen group 40 is thinned. In addition, the second groove is filled with optical glue, and the optical glue is in contact with the display layer 42, thereby ensuring that when the electronic device is in the unfolded state, the optical glue can effectively support the protective layer 41, making the flexible screen group 40 relatively flat, and avoiding the problem that the protective layer 41 may be concave when the electronic device is in the unfolded state, causing the flexible screen group 40 to be uneven.

[0044] In addition, the second groove and the third groove are filled with optical glue, which has a low elastic modulus and the characteristics of easy shear slip deformation, and can reduce the distribution of the stress gradient of the flexible screen group 40. Moreover, the optical glue is usually a non-Newtonian fluid, which itself has a strong internal friction damping property, so when the second part 402 of the flexible screen group 40 is impacted, the optical glue in the second groove and the optical glue in the third groove can also effectively absorb the impact kinetic energy, thereby reducing the risk of failure of the flexible screen group 40.

[0045] In addition, in some embodiments, the flexible screen group 40 may have a first part 401, a second part 402 and a third part 403; the first part 401 is opposite to the first shell 10, the connection between the first shell 10 and the second shell 20 is opposite to the second part 402, and the third part 403 is opposite to the second shell 20; the protective layer 41 located in the second part 402 forms a sawtooth structure 100 on the surface facing the display layer 42.

[0046] Since the sawtooth structure 100 is formed on the surface of the protective layer 41 of the second part 402 facing the display layer 42, the thickness of the second part 402 of the flexible screen group 40 is different from that of the first part 401 and the third part 403, that is, the sawtooth structure 100 is formed on the surface of the protective layer 41 of the second part 402 facing the display layer 42, and the thickness of the flexible second part 402 is adjusted. Moreover, the existence of the sawtooth structure 100 reduces the bending stress of the second part 402 of the flexible screen group 40 when the electronic device switches between the folded state and the unfolded state, thereby extending the service life of the flexible screen group 40. That is, by forming the sawtooth structure 100 on the surface of the protective layer 41 of the second part 402 of the flexible screen group 40 facing the display layer 42, the bending stress of the second part 402 of the flexible screen group 40 when the electronic device is in the folded state can be effectively reduced, and the stress gradient distribution of the flexible screen group 40 can be reduced, thereby effectively improving the service life of the flexible screen group 40.

[0047] In addition, in some embodiments, Figure 4 and Fig. 9 As shown, the first part 401 may have a first bending portion 4011, and the third part 403 may have a second bending portion 4021. The first bending portion 4011 and the second part 402 are both spaced apart from the second part 402; the protective layer 41 located at the first bending portion 4011 forms a sawtooth structure 100 on the surface facing the display layer 42, and the protective layer 41 located at the second bending portion 4021 forms a sawtooth structure 100 on the surface facing the display layer 42.

[0048] When the electronic device is switched between a folded state and an unfolded state, the first bending portion 4011 and the second bending portion 4021 will also be slightly bent and thus be subjected to bending stress. In the embodiment of the present application, a serrated structure 100 is formed on the surface of the protective layer 41 located at the first bending portion 4011 facing the display layer 42, and a serrated structure 100 is formed on the surface of the protective layer 41 located at the second bending portion 4021 facing the display layer 42. When the electronic device is switched between a folded state and an unfolded state, the bending stress borne by the first bending portion 4011 and the second bending portion 4021 is reduced, so that the stress distribution gradient of the flexible screen group 40 is reduced. Finally, when the electronic device is in the folded state, the bending stress borne by the first bending portion 4011 and the second bending portion 4021 of the flexible screen group 40 is reduced, so that the service life of the flexible screen group 40 is extended.

[0049] In addition, in some embodiments, the sawtooth structure 100 extends from the first portion 401 to the third portion 403 , and the sawtooth structure 100 includes a plurality of teeth 110 , and there is a gap between two adjacent teeth 110 , the gap is filled with optical glue, and the optical glue is in contact with the display layer 42 .

[0050] Since the gap between two adjacent teeth 110 is filled with optical glue, and the optical glue is in contact with the display layer 42, it can be ensured that when the electronic device is in the unfolded state, the optical glue can effectively support the protective layer 41, so that the flexible screen group 40 is relatively flat, and avoid the problem that the protective layer 41 may be concave when the electronic device is in the unfolded state, causing the flexible screen group 40 to be uneven. In addition, the optical glue has a low elastic modulus and the characteristics of easy shear slip deformation, which can reduce the distribution of stress gradients in the flexible screen group 40. Moreover, the optical glue is usually a non-Newtonian fluid, which itself has a strong internal friction damping property, so when the flexible screen group 40 is impacted, the optical glue can also effectively absorb the impact kinetic energy, thereby reducing the risk of failure of the flexible screen group 40.

[0051] In addition, in some embodiments, Figure 2 and Figure 7 As shown, the first shell 10 and the second shell 20 are hinged by a hinge assembly 200, and the electronic device may further include a shielding member 50; the shielding member 50 includes a first shielding plate 51 and a second shielding plate 52, the second shielding plate 52 is connected to the first shielding plate 51, and the first shielding plate 51 is parallel to the second shielding plate 52; a first avoidance groove 101 is provided on the first shell 10, and a second avoidance groove 201 is provided on the second shell 20, a part of the first shielding plate 51 is located in the first avoidance groove 101, a part of the first shielding plate 51 is located in the second avoidance groove 201, the second shielding plate 52 is located in both the first shell 10 and the second shell 20, and the second shielding plate 52 shields the hinge assembly 200.

[0052] Since the first housing 10 is provided with a first avoidance groove 101, the second housing 20 is provided with a second avoidance groove 201, and the first housing 10 and the second housing 20 are hingedly connected through the hinge assembly 200, when the shielding member 50 is installed in the electronic device, the first shielding plate 51 can be partially located in the first avoidance groove 101, the first shielding plate 51 can be partially located in the second avoidance groove 201, and the second shielding is simultaneously located in the first housing 10 and the second housing 20, and the second shielding plate 52 shields the hinge assembly 200 to prevent the hinge assembly 200 from being exposed, thereby causing dust or impurities to easily enter the hinge assembly 200, affecting the performance of the hinge assembly 200, and also improving the aesthetics of the electronic device. That is, by providing the shielding member 50, the hinge assembly 200 can be effectively protected, and the aesthetics of the electronic device can be improved.

[0053] It should be noted that in the embodiments of the present application, electronic devices include but are not limited to controllers, smart devices, terminal products and other devices, where smart devices are, for example, smart phones, smart TVs, smart speakers, smart robots, VR devices, AR devices, XR devices and other devices, and terminal products include personal computers, tablet computers and other products.

[0054] In the embodiment of the present application, since the first shell 10 and the second shell 20 are hinged, the electronic device can be switched between the folded state and the unfolded state by applying force to the first shell 10 and / or the second shell 20. Since the edge of the first shell 10 away from the second shell 20 and the edge of the second shell 20 away from the first shell 10 are both provided with decorative elements 30, the decorative elements 30 can decorate the first shell 10 and the second shell 20, thereby improving the aesthetics of the electronic device. Since the outer surface of the decorative piece 30 is provided with a step structure 301, the step structure 301 has a parallel first surface 302 and a second surface 303, the edge of the protective layer 41 is connected to the first surface 302, the edge of the display layer 42 is in contact with the second surface 303, and the display layer 42 is movable relative to the second surface 303. Therefore, when force is applied to the first shell 10 and / or the second shell 20 to switch the electronic device between the folded state and the unfolded state, the distance between the edge of the display layer 42 and the step structure 301 will change, and when the electronic device is in the unfolded state, the edge of the display layer 42 is close to the step structure 301, and the first surface 302 and the second surface 303 are not blocked, so that the display layer 42 is not blocked at all, thereby improving the screen-to-body ratio of the display screen. That is, in the embodiment of the present application, a step structure 301 is provided on the surface of the decorative member 30 facing away from the first shell 10 and the second shell 20, and the edge of the protective layer 41 is connected to the first surface 302, and the edge of the display layer 42 is in contact with the second surface 303, so that when the electronic device switches between the folded state and the unfolded state, the distance between the display layer 42 and the step structure 301 changes, and when the electronic device is in the unfolded state, even if the display layer 42 is close to the step structure 301, the display layer 42 is not blocked by any components. In addition, the width of the decorative member 30 does not need to be increased, so that the display area of ​​the electronic device can be increased and the screen-to-body ratio of the electronic device can be improved.
