[0002] In order to meet people's requirements for the screen size of electronic devices, electronic devices with foldable screens (such as mobile phones and tablet computers, etc.) have come into being. Among them, foldable screen electronic devices usually include two frames, and the two frames can rotate relative to each other so that the electronic device is in an unfolded state and a folded state respectively; in the unfolded state, the display screens on the two frames are in the same plane, so that the display area of ​​the electronic device is increased; and in the folded state, the two frames are stacked on each other, so that the size of the electronic device is reduced, so that it is convenient for users to pick up and carry.

[0027] See also Figure 1 and Figure 2 , is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application, and the electronic device may include a mobile phone or a tablet computer, etc. Figure 1 and Figure 2 As shown, the electronic device includes:

[0028] A first frame body 10 and a second frame body 20, wherein at least one of the first frame body 10 and the second frame body 20 is provided with a first stopper 100;

[0029] The hinge assembly 30 includes a swing arm bracket 31, a first swing arm 32 and a second swing arm 33. The first swing arm 32, the second swing arm 33 are rotatably connected to the swing arm bracket 31. A second limit piece 300 is provided on the side of the swing arm bracket 31 near at least one of the first swing arm 32 and the second swing arm 33. The first swing arm 32 is connected to the first frame 10, and the second swing arm 33 is connected to the second frame 20. When the swing arm bracket 31 rotates relative to the first swing arm 32 and the second swing arm 33, the electronic device can be in a folded state.

[0030] In the folded state, the second limiting member 300 abuts against the first limiting member 100 , and the first limiting member 100 cooperates with the second limiting member 300 to limit the swing arm bracket 31 from escaping from at least one frame.

[0031] Based on this, at least one of the first frame 10 and the second frame 20 of the electronic device is provided with a first limiter 100, and the swing arm bracket 31 in the hinge assembly 30 is provided with a second limiter 300 near the side of at least one of the first swing arm 32 and the second swing arm 33, and the swing arm bracket 31 and the first swing arm 32 and the second swing arm 33 can rotate relative to each other, so that the electronic device is in a folded state, and when the electronic device is in the folded state, the second limiter 300 abuts against the first limiter 100, thereby limiting the swing arm bracket 31 from escaping from at least one frame. In this way, when the electronic device is in the folded state, due to the cooperation between the second limiter 300 and the first limiter 100, it is possible to limit the swing arm bracket 31 from escaping from at least one frame, thereby improving the reliability of the electronic device.

[0032] In the embodiment of the present application, the electronic device includes a first frame body 10 and a second frame body 20 .

[0033] The electronic device is an electronic device with a foldable screen, which generally includes at least two frames each provided with a screen, and the first frame 10 and the second frame 20 may be adjacent frames of the at least two frames.

[0034] The first frame 10 and the second frame 20 can be relatively rotated so that the first frame 10 and the second frame 20 are stacked on each other, and the electronic device is in a folded state; or the first frame 10 and the second frame 20 can be rotated to be in the same plane, and the electronic device is in an unfolded state.

[0035] For example, the above-mentioned electronic device may include a frame A and a frame B, frame A and frame B are respectively provided with screens, and frame A and frame B can rotate relative to each other. If the user has a demand for a large-size screen, frame A and frame B can be rotated to an angle of 180°, and the electronic device is in an unfolded state; or, frame A and frame B can be rotated to overlap each other (such as an angle less than 5°, etc.), and the electronic device is in a folded state.

[0036] At least one of the first frame 10 and the second frame 20 is provided with a first limiter 100. The first limiter 100 can cooperate with the second limiter 300 when the electronic device is in a folded state to limit the movement of the at least one frame away from the hinge assembly 30, thereby limiting the swing arm bracket 31 from escaping from the structure of at least one frame.

[0037] At least one of the first frame body 10 and the second frame body 20 is provided with the first limiter 100 . Only the first frame body 10 or the second frame body 20 may be provided with the first limiter 100 , or both the first frame body 10 and the second frame body 20 may be provided with the first limiter 100 .

[0038] In the embodiment of the present application, the electronic device further comprises a hinge assembly 30, and the hinge assembly 30 is used to connect the first frame 10 and the second frame 20 so that the first frame 10 and the second frame 20 can rotate relative to each other.

[0039] It should be noted that, when the above-mentioned electronic device includes more than two frames, the above-mentioned electronic device may include multiple hinge assemblies 30, and each hinge assembly 30 is connected between two adjacent frames so that the two adjacent frames can rotate relative to each other, and the two frames connected by each hinge assembly 30 can be understood as the above-mentioned first frame 10 and the second frame 20.

[0040] The above-mentioned hinge assembly 30 may include a swing arm bracket 31, a first swing arm 32 and a second swing arm 33. The first swing arm 32, the second swing arm 33 are rotatably connected to the swing arm bracket 31, the first swing arm 32 is connected to the first frame 10, and the second swing arm 33 is connected to the second frame 20. When the swing arm bracket 31 and the first swing arm 32, the second swing arm 33 rotate relative to each other, the electronic device can be in a folded state.

[0041] The swing arm bracket 31 is used to support the first swing arm 32 and the second swing arm 33 so that the first swing arm 32 and the second swing arm 33 can rotate around it respectively. The swing arm bracket 31 can be a whole; or Figure 3 As shown, the swing arm bracket 31 may also include two bracket bodies 311 spaced apart, and the two bracket bodies 311 are movably connected to the first swing arm 32 and the second swing arm 33, respectively, and the first swing arm 32 and the second swing arm 33 can simultaneously rotate relative to the two bracket bodies 311. Of course, the swing arm bracket 31 may also include three or more bracket bodies 311, which is not limited here.

[0042] The first swing arm 32 may be fixedly connected to the first frame 10 on one side and movably connected to the swing arm bracket 31 on the other side, and may rotate relative to the swing arm bracket 31, so that the first frame 10 and the swing arm bracket 31 may rotate relative to each other. The first swing arm 32 may also be a whole; or, in the case where the swing arm bracket 31 includes at least two bracket bodies 311, the first swing arm 32 may also include at least two first arm bodies 321, the two first arm bodies 321 are movably connected to the two bracket bodies 311 in a one-to-one correspondence, and each first arm body 321 may rotate relative to its corresponding bracket body 311.

[0043] Similarly, the second swing arm 33 may be fixedly connected to the second frame 20 on one side and movably connected to the swing arm bracket 31 on the other side, and may rotate relative to the swing arm bracket 31, so that the second frame 20 and the swing arm bracket 31 may rotate relative to each other. The second swing arm 33 may also be a whole; or, in the case where the swing arm bracket 31 includes at least two bracket bodies 311, the second swing arm 33 may also include at least two second arm bodies 331, the two second arm bodies 331 are movably connected to the two bracket bodies 311 in a one-to-one correspondence, and each second arm body 331 may rotate relative to its corresponding bracket body 311.

[0044] The above-mentioned swing arm bracket 31 is provided with a second limiting member 300 on the side of at least one of the first swing arm 32 and the second swing arm 33. The second limiting member 300 can be any structure that can cooperate with the first limiting member 100 to limit the swing arm bracket 31 from escaping from at least one frame when the electronic device is in a folded state.

[0045] The above-mentioned swing arm bracket 31 is provided with a second limiting piece 300 on the side of at least one of the first swing arm 32 and the second swing arm 33. It can be that when one of the above-mentioned first frame 10 and the second frame 20 is provided with the first limiting piece 100, the swing arm bracket 31 is provided with a second limiting piece 300 on the side of the swing arm connected to the one frame to limit the swing arm bracket 31 from escaping from the one frame.

[0046] For example, in the case where a lock hook is provided on the above-mentioned first frame body 10, a lock buckle may be provided on the side of the above-mentioned swing arm bracket 31 close to the above-mentioned first swing arm 32. If the electronic device is in a folded state, the lock hook and the lock buckle are engaged, so that the first frame body 10 cannot move in the direction X away from the swing arm bracket 31, so as to limit the swing arm bracket 31 from escaping from the first frame body 10; similarly, in the case where a lock hook is provided on the above-mentioned second frame body 20, a lock buckle may be provided on the side of the above-mentioned swing arm bracket 31 close to the above-mentioned second swing arm 33. If the electronic device is in a folded state, the lock hook and the lock buckle are engaged, so that the second frame body 20 cannot move in the direction X away from the swing arm bracket 31, so as to limit the swing arm bracket 31 from escaping from the second frame body 20.

[0047] Of course, the above-mentioned swing arm bracket 31 is provided with a second limiting member 300 on the side close to at least one of the first swing arm 32 and the second swing arm 33. It can also be that when the above-mentioned first frame 10 and the second frame 20 are both provided with the first limiting member 100, the swing arm bracket 31 is respectively provided with a second limiting member 300 on the side close to the first frame 10 and the second frame 20 to limit the swing arm bracket 31 from escaping from the first frame 10 and the second frame 20.

[0048] In some embodiments, Figure 5 As shown, the first limiting member 100 is a reinforcing rib, and the reinforcing rib is formed by extending the frame.

[0049] like Figure 6 As shown, the second limiting member 300 may be a protrusion, and the protrusion is formed by extending the swing arm bracket 31 .

[0050] When the electronic device is in a folded state, the reinforcing rib and the protrusion may be located in the gap between the swing arm bracket 31 and the frame, and the reinforcing rib abuts against the protrusion.

[0051] Based on this, reinforcing ribs are extended on the frame (which can be at least one of the above-mentioned frames) and protrusions are extended on the swing arm bracket 31, so that when the electronic device is in a folded state, the reinforcing ribs can abut against the protrusions to limit the movement of the frame in a direction away from the swing arm bracket 31, thereby limiting the swing arm bracket 31 from escaping from the frame, thereby making the structure of the first limit member 100 and the second limit member 300 more solid, thereby improving the reliability of the electronic device.

[0052] For example, when the first frame 10 is provided with reinforcing ribs, a protrusion is provided on the side of the swing arm bracket 31 close to the first swing arm 32, and when the electronic device is in a folded state, the reinforcing rib of the first frame 10 abuts against the protrusion on the side of the swing arm bracket 31 close to the first swing arm 32; when the second frame 20 is provided with reinforcing ribs, a protrusion is provided on the side of the swing arm bracket 31 close to the second swing arm 33, and when the electronic device is in a folded state, the reinforcing rib of the second frame 20 abuts against the protrusion on the side of the swing arm bracket 31 close to the second swing arm 33.

[0053] When the electronic device is in a folded state, the above-mentioned reinforcing rib abuts against the protrusion, which may be in a direction parallel to the plane of the above-mentioned frame and away from the swing arm bracket 31. When the electronic device is in a folded state, the above-mentioned protrusion is located in front of the reinforcing rib, so that when the frame is subjected to a thrust in the direction away from the swing arm bracket 31, the protrusion can block the movement of the reinforcing rib in the direction away from the swing arm bracket 31. The reinforcing rib is formed by extending from the frame, thereby limiting the movement of the frame in the direction away from the swing arm bracket 31, thereby limiting the swing arm bracket 31 from escaping from the frame.

[0054] When the second limiting member 300 is a protrusion, the side of the swing arm bracket 31 (which may be the side close to the first swing arm 32 or the second swing arm 33) may be provided with only one protrusion, and the position of the protrusion on the side of the swing arm bracket 31 may be set according to actual needs.

[0055] For example, when the swing arm bracket 31 is an integral body, the protrusion may be provided at the center of the side of the swing arm bracket 31 .

[0056] In some embodiments, a plurality of protrusions are disposed on the swing arm bracket 31 , and the plurality of protrusions are disposed at intervals along the side of the swing arm bracket 31 .

[0057] Based on this, by setting a plurality of protrusions at intervals on the swing arm bracket 31, the plurality of protrusions can cooperate with the above-mentioned reinforcing ribs to jointly limit the movement of the first frame 10 in a direction away from the hinge assembly 30, thereby enhancing the force bearing capacity between the protrusions and the reinforcing ribs, thereby making the reliability of the electronic device higher.

[0058] The plurality of protrusions are arranged at intervals along the side of the swing arm bracket 31 , and may be arranged at intervals along the side of the swing arm bracket 31 in a direction Y perpendicular to the rotation plane of the frame.

[0059] In the case where a plurality of protrusions are arranged at intervals on the side of the swing arm bracket 31 , the distribution positions of the plurality of protrusions can be set as required. For example, the plurality of protrusions can be arranged close to the center position of the side of the swing arm bracket 31 .

[0060] In some embodiments, the swing arm bracket 31 includes two bracket bodies 311 , the two bracket bodies 311 are arranged at an interval, and a plurality of protrusions are distributed on the two bracket bodies 311 .

[0061] Based on this, by distributing a plurality of protrusions on the two bracket bodies 311 of the swing arm bracket 31, the force distribution is made more balanced, thereby further improving the limiting capability and the reliability of the electronic equipment.

[0062] The plurality of protrusions are distributed on the two bracket bodies 311, and the number of protrusions distributed on the two bracket bodies 311 may be different; or, in the case where the swing arm bracket 31 is provided with an even number of protrusions, the number of protrusions distributed on the two protrusion brackets may be the same. For example, the side edges of the swing arm bracket 31 close to the first swing arm 32 may be provided with four protrusions, and each bracket body 311 may be provided with two protrusions, and so on.

[0063] The reinforcing ribs are formed by extending the frame, and when the electronic device is in a folded state, the reinforcing ribs extend from the frame toward the swing arm bracket 31 , so that the reinforcing ribs protrude into the gap between the frame and the swing arm bracket 31 .

[0064] The shape and size of the reinforcing ribs can be set as needed. For example, when the swing arm bracket 31 is provided with a plurality of protrusions, the reinforcing ribs can include a plurality of rib sections, and along the direction Y perpendicular to the rotation plane of the frame, the plurality of rib sections are arranged at intervals on the side of the frame close to the swing arm bracket 31, and the plurality of rib sections are arranged in one-to-one correspondence with the plurality of protrusions, and when the electronic device is in a folded state, each rib section abuts against its corresponding protrusion.

[0065] In some embodiments, in the folded state, the reinforcing ribs are formed extending along the gap between the swing arm bracket 31 and the frame.

[0066] Based on this, in the folded state, the reinforcing ribs extend along the gap between the swing arm bracket 31 and the first frame body 10, which can not only enhance the force-bearing capacity of the reinforcing ribs, but also enable the reinforcing ribs to block the gap between the swing arm bracket 31 and the frame body, thereby improving the dustproof ability and appearance of the electronic device in the folded state.

[0067] For example, when a protrusion is provided on the side of the swing arm bracket 31 close to the first swing arm 32, the gap between the swing arm bracket 31 and the first frame 10 can be extended to form a reinforcing rib; when a protrusion is provided on the side of the swing arm bracket 31 close to the second swing arm 33, the gap between the swing arm bracket 31 and the second frame 20 can be extended to form a reinforcing rib.

[0068] The reinforcing rib is located in the gap between the frame and the swing arm bracket 31 , and the reinforcing member may be located in the gap between the frame and the bracket body 311 .

[0069] In some embodiments, the swing arm bracket 31 further includes a cover plate 34 , and the cover plate 34 is connected to the swing arm bracket 31 .

[0070] When the electronic device is in a folded state, the cover 34 can cover the bracket body 311 of the swing arm bracket 31 and be spaced apart from the frame, and the reinforcing ribs are located in the gap between the cover 34 and the frame.

[0071] Based on this, when the electronic device is in a folded state, the reinforcing ribs are located in the gap between the cover plate 34 and the frame body, thereby further improving the dustproof capability and aesthetic appearance of the electronic device in the folded state.

[0072] The cover plate 34 may be any plate structure that is connected to the bracket body 311 and is used to cover the bracket body 311 to prevent the bracket body 311 from being exposed, and may be made of materials such as plastic or metal.

[0073] In some embodiments, when the electronic device is in a folded state, the reinforcing ribs match the edges of the cover plate 34 that are disposed opposite to each other.

[0074] Based on this, by setting reinforcing ribs to match the edges of the cover plate 34 , the dustproof capability and aesthetic appearance of the electronic device in the folded state can be further improved.

[0075] The above-mentioned reinforcing ribs match the edges of the cover plate 34 set opposite to each other. It can be understood that when the electronic device is in a folded state, the reinforcing ribs match the side shapes of the cover plate 34 set opposite to each other, and the distance of the gap between the two at any position is close (that is, the gap is less than a preset value, such as 1 mm, etc.).

[0076] In the case where the reinforcing ribs match the edges of the cover plate 34, the shapes of the sides of the reinforcing ribs and the cover plate 34 can be set according to actual needs. For example, the reinforcing ribs can be set as right-angled ribs, and the edges of the cover plate 34 can be right-angled edges that match the right-angled ribs, and so on.

[0077] In some embodiments, the cover plate 34 is provided with a first arc-shaped edge 341 , and the reinforcing rib is provided with a second arc-shaped edge 101 . When the electronic device is in a folded state, the second arc-shaped edge 101 matches the first arc-shaped edge 341 .

[0078] Based on this, by setting the cover plate 34 to have a first arcuate edge 341 and the reinforcing rib to have a second arcuate edge 101, when the electronic device is in a folded state, the second arcuate edge 101 matches the second arcuate edge 101, thereby improving the appearance of the electronic device in the folded state.

[0079] For example, Figure 7 As shown, when the cover plate 34 is provided with an arc edge (i.e., the first arc edge 341) near the side of the first frame body 10, the reinforcing rib of the first frame body 10 is also provided with an arc rib position (i.e., the second arc edge 101) at a position opposite to the arc edge in the folded state, so that the distance between any position of the gap between the cover plate 34 and the reinforcing rib is close.

[0080] Of course, the reinforcing ribs may not match the side surfaces of the cover plate 34, which is not limited here. Figure 8 As shown, in the case where the cover plate 34 is provided with an arc edge near the side of the first frame body 10, the reinforcing ribs of the first frame body 10 are at right angles to the arc edge in the folded state, so that the distance of the gap between the arc edge and the right angle rib is greater than the spacing at other positions.

[0081] In some embodiments, the reinforcing rib is disposed near an edge of the frame to which the swing arm is connected.

[0082] Based on this, by arranging reinforcing ribs close to the edge of the frame connected to the swing arm, the appearance of the electronic device in the folded state can be further improved.

[0083] In the embodiment of the present application, the above-mentioned reinforcing ribs are arranged near the edge of the frame connected to the swing arm. It can be that when the first frame 10 is provided with reinforcing ribs, the reinforcing ribs of the first frame 10 are arranged near the edge of the first swing arm 32; similarly, when the second frame 20 is provided with reinforcing ribs, the reinforcing ribs of the second frame 20 are arranged near the edge of the second swing arm 33.

[0084] The abutment between the first limiting member 100 and the second limiting member 300 may be point contact between the first limiting member 100 and the second limiting member 300, or may be surface contact between the first limiting member 100 and the second limiting member 300.

[0085] In the case of surface contact between the first stopper 100 and the second stopper 300, the contact surface between the first stopper 100 and the second stopper 300 may be a plane or an inclined surface. Fig. 9 The plane where the contact surface of the first stopper 100 and the second stopper 300 is located may be perpendicular to the first frame 10; or Fig.10 As shown, the plane where the contact surface of the first limiting member 100 and the second limiting member 300 is located can be inclined with respect to the first frame body 10, and so on.

[0086] Alternatively, the contact surface between the first limiting member 100 and the second limiting member 300 is a curved surface.

[0087] Based on this, the contact surface between the first limit member 100 and the second limit member 300 is a curved surface, which not only makes the setting method of the contact surface more flexible, but also can further increase the contact area between the first limit member 100 and the second limit member 300, thereby improving the force bearing capacity between the first limit member 100 and the second limit member 300.

[0088] In some embodiments, the electronic device further comprises:

[0089] An elastic member (not shown), the elastic member is connected to at least one of the first limiting member 100 and the second limiting member 300 .

[0090] Among them, in the folded state, the elastic member can be sandwiched between the first stopper 100 and the second stopper 300. Based on this, by providing the elastic member, in the folded state, the elastic member can be sandwiched between the first stopper 100 and the second stopper 300, so that the sealing performance between the first stopper 100 and the second stopper 300 is better.
