Various changes, modifications and equivalents of the methods, devices and / or systems described herein will become apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to those orders set forth herein, but can be changed as becomes apparent after understanding the present disclosure, except for operations that must be performed in a specific order. In addition, for clarity and brevity, descriptions of features known in the art may be omitted.

[0038] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] The present disclosure provides a support assembly and an electronic device. Figures 1 to 14 , the supporting components and electronic equipment in the embodiments of the present disclosure are described in detail.

[0040] The electronic devices mentioned here can be terminal devices with display screens, such as mobile phones, tablets, and wearable devices.

[0041] Please refer to Figure 1 , and when necessary, combine Figures 2 to 13 As shown, the electronic device 100 includes a supporting structure 10 and a display screen 20 .

[0042] The support structure 10 includes two support components 11 and a rotating shaft component 13. The two support components 11 are foldably connected via the rotating shaft component 13.

[0043] The display screen 20 may be a folding screen. The display screen 20 is disposed on the support structure 10 and can be unfolded or folded along with the two support components 11 .

[0044] The display screen 20 may include a first portion 21 disposed on one support assembly 11, a second portion 22 disposed on another support assembly 11, and a third portion 23 connected therebetween. The third portion 23 is disposed on one side of the hinge assembly 13 and may be flattened or bent as the hinge assembly 13 is unfolded or folded.

[0045] Please combine Figure 2 As shown, in some embodiments, the display screen 20 of the foldable electronic device 100 can be folded inwards, that is, the end of the foldable electronic device 100 in the length direction S1 can be folded inwards. Figure 2 The directional lines 101 and 102 are shown as folding. When the display screen 20 of the foldable electronic device 100 is folded outward to any folding position, the display screen 20 has a corresponding outward folding or unfolding state.

[0046] It is understandable that S1 here is the length direction of the foldable electronic device 100, and S2 is the width direction of the foldable electronic device 100. Of course, in some other embodiments, S1 may also be the width direction of the foldable electronic device 100, and S2 may be the length direction of the foldable electronic device 100.

[0047] Of course, in some other embodiments, the display screen of the foldable electronic device can also be folded outward (ie, folded in the direction opposite to the directed line segments 101 and 102), or can only be folded inward.

[0048] In some embodiments, the support assembly 11 may include a support member 111 and a housing respectively disposed on a side of the support member facing away from the display screen 20 .

[0049] In some embodiments, the support member 111 is a middle frame.

[0050] In other embodiments, the outer shell and the support member of the support assembly may be an integral structure, or the outer shell may not be included, and the support member of the support assembly may also partially directly serve as its outer shell.

[0051] The rotating shaft assembly 13 includes a rotating shaft seat 131 .

[0052] The two support members 111 are rotatably connected to opposite sides of the shaft seat 131 along the first direction S1', and the two support members 111 can be relatively unfolded or folded when they rotate relative to the shaft seat 131. Accordingly, the display screen 20 can be unfolded or folded when the two support members 111 rotate relative to the shaft seat 131.

[0053] When the two supporting members 111 rotate relative to the rotating shaft seat 131 to a fully unfolded or bent folded state, the first direction S1 ′ may be consistent with the length direction S1 of the foldable electronic device 100 .

[0054] Each of the support members includes a support body and two relative limiting portions located on the support body and arranged relative to each other in the second direction S2. The support body and the two relative limiting portions enclose a setting space, and the two relative limiting portions are each provided with a track groove extending in a curved shape; the track groove includes an unfolding stop and a folding stop.

[0055] Combination Figures 2 to 9 As shown, the support member 111 includes a support body 1110 and two opposite limiting portions 1111 located on a side of the support body 1110 close to the shaft seat 131 and opposite to each other in the second direction S2. Fig. 9 The figure shows a limiting portion 1111 at one end, the support body 1110 and the two limiting portions 1111 form a setting space 1001, and the two opposite limiting portions 1111 are each provided with a track groove 103 extending in a curved shape; the track groove 103 has an unfolding stop 10302 at one end and a folding stop 10301 at the end away from the unfolding stop 10302.

[0056] The two opposite ends of the shaft seat 131 in the second direction S2 are provided with positioning posts 1310 respectively corresponding to the track slots 103 of the two support members 111. The shaft seat 131 is at least partially located in the setting space 1001, and each positioning post 1310 is located in the corresponding track slot 103. When the two support members 111 rotate relative to the shaft seat 131, the positioning posts 1310 are located at different positions in the corresponding track slots 103.

[0057] Combination Figures 2 to 4 as well as Figure 6 As shown, when each positioning column 1310 is located at the expansion stop 10302 of the corresponding track slot 103, the two support members 111 are expanded to a completely flat state, thereby improving the stability of the electronic device when expanded, improving the accuracy of the expansion angle, and thus improving the user experience. At this time, the two support members 111 can be in the same plane, and the angle between the two support members 111 can be 180°.

[0058] Combination Figure 5 and Fig.10 As shown, when each positioning column 1310 is located at the folding stop 10301 of the corresponding track slot 103, the two support members 111 are in a completely folded state, and the angle between the two support members 111 is 0°. When the shaft seat is subjected to force, the cooperation between the positioning column and the track slot greatly reduces the displacement between the shaft seat and the support members such as the middle frame, thereby reducing the probability of screen damage and improving the reliability of the whole machine.

[0059] It should be noted that the positioning column 1310 is fixed to the shaft seat 131. The track slot 103 is determined according to the running track of the positioning column 1310 during the rotation of the two support members 111 relative to the shaft seat 131 and is adapted to the corresponding positioning column 1310.

[0060] Combination Figure 7 , Figure 8 and Fig. 9 The two supporting members 111 are shown in different folding states between a fully folded state and a flattened state during the rotation process relative to the rotating shaft seat 131. Figure 7 The angle between the two support members 111 is approximately 120°. Figure 8 The angle between the two support members 111 is substantially 90°. Fig. 9 The angle between the two support members 111 can be 60°.

[0061] In some embodiments, each of the support members has a first side 1113 close to the shaft seat 131 and a second side 1114 away from the shaft seat 131; the shaft seat 131 has a first surface Q1 and a second surface Q2 opposite to each other in the thickness direction, and when the two support members 111 are folded, the second side 1114 of the two support members 111 are located on the side where the first surface Q1 of the shaft seat 131 is located.

[0062] Among them, the track groove 103 is provided with a folding stop portion at the folding stop position 10301, and the folding stop portion is located on the side of the folding stop position 10301 away from the first side 1113. When the positioning column 1310 is located at the folding stop position 10301, the folding stop portion can prevent the positioning column 1310 from moving relative to each other in the direction from the first side 1113 toward the second side 1114.

[0063] The track groove 103 is provided with an expansion stop portion at the expansion stop position 10302, and the expansion stop portion is located on the side of the expansion stop position 10302 close to the first side 1113. When the positioning column 1310 is located at the expansion stop position 10302, the expansion stop portion can prevent the positioning column 1310 from moving relative to each other in the direction from the first side 1113 toward the second side 1114.

[0064] It should be noted that when the positioning column 1310 is located at the corresponding expansion stop 10302 and is blocked by the corresponding expansion stop portion, when a certain preset force is applied to the two support components 11, the positioning column 1310 can move from the corresponding expansion stop 10302 to enable the electronic device to be folded.

[0065] Accordingly, when the positioning column 1310 is located at the corresponding folding stop position 10301 and is blocked by the corresponding folding stop portion, when a certain preset force is applied to the two first support components 11, the positioning column 1310 can move from the corresponding folding stop position 10301 to enable the electronic device to be unfolded.

[0066] The arrangement of the unfolding stopper can further enhance the stability of the electronic device in a fully unfolded state. The arrangement of the folding stopper can further enhance the stability of the electronic device in a fully folded state.

[0067] In some embodiments, the trajectory groove 103 has a first groove wall 1031 and a second groove wall 1032 on opposite sides in the length direction of the trajectory groove 103; wherein, the middle part of the trajectory groove 103 in the length direction protrudes toward the side where the second groove wall 1032 is located, and the part 1033 of the middle part of the first groove wall 1031 protruding toward the second groove wall 1032 forms the folding stop portion and the unfolding stop portion.

[0068] In some embodiments, at least a portion of the positioning column 1310 is a plane 13101. When the positioning column 1310 is located at the folding stop position 10301, the plane 13101 can cooperate with the folding stop portion. When the positioning column 1310 is located at the unfolding stop position 10302, the plane 13101 can cooperate with the unfolding stop portion.

[0069] The plane 13101 may be a surface of the positioning post 1310 close to the first surface Q1 .

[0070] In some embodiments, the cross section of the positioning post 1310 is rectangular, or the cross section is rectangular as a whole with rounded corners, which is convenient for manufacturing and matching with the track slot 103.

[0071] In some implementations, the shaft assembly 13 further includes two shaft connectors 132 , and the two support members 111 are rotatably connected to opposite sides of the shaft seat 131 along the first direction S1 ′ via a corresponding shaft connector 132 .

[0072] The two rotating shaft connectors 132 can be rotatably connected to the rotating shaft seat 131 at two opposite sides along the first direction S1 ′ via a rotating connection structure such as a rotating shaft.

[0073] Each of the supporting members and the rotating shaft assembly 13 is provided with a matching connecting hole, and the connecting hole of the supporting member and the connecting hole of the rotating shaft assembly 13 are connected via a fixing member.

[0074] In some embodiments, the track slot 103 penetrates part of the thickness of the limiting portion in the second direction S2, which is beneficial to ensure the strength of the support member as much as possible, ensure the beautiful structure, and not affect the arrangement of other structures.

[0075] Combination Fig.11 As shown, the support member 111 is provided with a connection hole 1101. Each rotating shaft connecting member 132 is provided with a corresponding connection hole to be matched and fixed with the corresponding connection hole 1101 respectively.

[0076] In some embodiments, the fixing member may be a bolt, a screw, a pin or the like.
