[0036] With the continuous development of electronic devices, portable electronic devices such as communication terminals, game consoles, multimedia devices, portable calculators and camera devices usually adopt a foldable structure, so that the electronic devices have a larger display area while meeting the portability requirements to meet the needs of users. Specifically, a common hinge mechanism usually includes a hinge and two fixed hinge brackets, and the two fixed hinges are respectively fixed to the first shell and the second shell.

The structure of the rotation axis assembly 110 provided in this embodiment is simple, and the relative position of the first support plate 120 and the second support plate 130 can be adjusted easily. In addition, the foldable mechanism 100 of the present embodiment includes a first rotating shaft 111 and a second rotating shaft 112. Compared with the solution of only setting one rotating shaft to be rotatably connected with the first support plate 120 and the second support plate 130 respectively, the first rotating shaft 111 and the second rotating shaft 112 of the present embodiment are arranged at intervals along the first direction, so that the first rotating shaft 111 is not interfered with by the position of the second support plate 130 during the rotation process, and the second rotating shaft 112 is not interfered with by the position of the first support plate 120 during the rotation process, so that when the foldable mechanism 100 is in a flattened state, the first support plate 120 and the second support plate 130 are coplanar. When the foldable mechanism 100 is applied to the foldable electronic device 200, the first support plate 120 and the second support plate 130 are used to carry the flexible display screen 210 and make different areas of the flexible display screen 210 on the same horizontal plane, which is conducive to improving the display effect of the foldable mechanism 100 when it is applied to the foldable electronic device 200 and improving the performance of the foldable mechanism 100.

When the foldable mechanism 100 changes from the flat state to the folded state, the mounting member 115 is driven by the second supporting plate 130 to slide relative to the second rotating shaft 112 in a direction away from the second rotating shaft 112, thereby driving the second rotating shaft 112 to rotate relative to the second rotating shaft bracket 114, and then driving the connecting bracket 116 and the first rotating shaft 111 to rotate relative to the first rotating shaft bracket 113, so that the foldable mechanism 100 is in the folded state and the first rotating shaft 111 and the second rotating shaft 112 are located on the same side of the first supporting plate 120 and the second supporting plate 130.

On the contrary, when the foldable mechanism 100 changes from the folded state to the flattened state, the mounting member 115 slides relative to the sliding member 1142 toward the direction close to the second rotating shaft 112 under the drive of the second supporting plate 130, that is, the sliding member 1142 slides relative to the second supporting plate 130 toward the direction away from the second rotating shaft 112, thereby driving the second rotating shaft 112 to rotate relative to the bracket body 1141 toward the direction away from the first supporting plate 120, and the first rotating shaft 111 rotates relative to the first rotating shaft bracket 113, so that the first supporting plate 120 and the second supporting plate 130 are coplanar. In the foldable mechanism 100 provided in this embodiment, the sliding connection between the sliding member 1142 and the mounting member 115 is realized, so that the sliding connection between the bracket body 1141 and the second supporting plate 130 is realized. When the second support plate 130 rotates relative to the first support plate 120, the bracket body 1141 slides relative to the second support plate 130, the shaft rotates relative to the bracket body 1141, and the connecting bracket 116 further drives the first shaft 111 to rotate relative to the first shaft bracket 113, and finally realizes the transition of the foldable mechanism 100 between the folded state and the flattened state. The sliding connection between the sliding member 1142 and the mounting member 115 improves the conversion efficiency of the foldable mechanism 100 between the folded state and the flattened state, thereby improving the performance of the foldable mechanism 100.

The damping subassembly 140 can make the relative sliding process of the support body 1141 and the mounting member 115 more stable, and can prevent the foldable mechanism 100 from being violently impacted during the conversion process between the folded state and the flattened state. When the foldable mechanism 100 is used in a foldable electronic device 200, the first support plate 120 and the second support plate 130 are used to support the flexible display screen 210, and the damping subassembly 140 can prevent the first support plate 120 and the second support plate 130 from being violently impacted and damaging the flexible display screen 210, thereby improving the performance of the foldable mechanism 100. Furthermore, during the switching process of the foldable mechanism 100 between the folded state and the flattened state, the damping subassembly 140 can increase the sliding torque of the bracket body 1141 and the mounting member 115, thereby improving the feel of switching the foldable mechanism 100 between the folded state and the flattened state, which is beneficial to improving the user experience.

[0056] See also Fig.12 and Fig.13 In some embodiments, the sliding member 1142 includes a sliding body 1143 and a fixing column 1144. The sliding body 1143 has a second direction (eg Fig.12The first slide groove 11431 extends along the Y direction (shown in the middle), the fixed column 1144 is arranged on the side of the sliding body 1143 away from the mounting member 115 and is spaced from the first slide groove 11431; the first slide groove 11431 has a first end 11432 and a second end 11433 arranged opposite to each other along the second direction, and the second end 11433 is arranged closer to the fixed column 1144 than the first end 11432; the damping subassembly 140 includes a moving member 141 and an elastic member 142, the moving member 141 can be slidably arranged in the first slide groove 11431 along the second direction, one end of the elastic member 142 is connected to the moving member 141, and the other end is connected to the fixed column 1144; the surface of the mounting member 115 facing the sliding member 1142 has a second slide groove 1151; the moving member 141 also slides The movable member 141 is movably arranged in the second slide groove 1151; the second slide groove 1151 extends along the first direction, and the second slide groove 1151 has a first position 1152 and a second position 1153 which are arranged relatively along the first direction, and the first position 1152 is arranged closer to the second rotating shaft 112 than the second position 1153, and when the movable member 141 is in the first position 1152 and the second position 1153, the movable member 141 is located at the first end 11432, and the elastic member 142 is in a relaxed state; when the movable member 141 is between the first position 1152 and the second position 1153, the movable member 141 is located between the first end 11432 and the second end 11433, and the elastic member 142 is in a compressed state, wherein the first direction intersects with the second direction, and the second direction is parallel to the second support plate 130.

[0057] It can be understood that the elastic member 142 is in a relaxed state, that is, the elastic member 142 is neither stretched nor compressed.

[0058] It can be understood that the two opposite ends of the elastic member 142 are connected to the moving member 141 and the fixing column 1144 respectively.

[0059] In this embodiment, when the moving member 141 is in the first position 1152 and the second position 1153, the moving member 141 is at the first end 11432 and the elastic member 142 is in a relaxed state. Then, when the moving member 141 is in a moving process from the first position 1152 to the second position 1153 or from the second position 1153 to the first position 1152, the moving member 141 slides between the first end 11432 and the second end 11433, and the elastic member 142 is always in a compressed state. The elastic member 142 is first elastically compressed and then gradually elastically recovered. During the switching process between the first position 1152 and the second position 1153, the moving member 141 realizes the relative sliding of the sliding member 1142 and the mounting member 115. The sliding member 1142, the moving member 141, the elastic member 142 and the mounting member 115 cooperate with each other to increase the torque during the relative sliding process between the sliding member 1142 and the mounting member 115.

On the other hand, the relative sliding feel of the second rotating shaft bracket 114 and the second supporting plate 130 can be improved, that is, the switching feel of the foldable mechanism 100 between the folding state and the flattened state can be improved, which is conducive to improving the user experience.

[0060] It can be understood that the first position 1152 is arranged closer to the second rotating shaft 112 than the second position 1153. Therefore, when the movable member 141 is in the first position 1152, the foldable mechanism 100 is in a folded state; when the movable member 141 is in the second position 1153, the foldable mechanism 100 is in an unfolded state.

[0061] Optionally, in some embodiments, the first direction is perpendicular to the second direction.

[0062] Optionally, the sliding body 1143 includes a first portion 11434, a second portion 11435, a third portion 11436, a fourth portion 11437 and a fifth portion 11438 that are connected by bending, the first portion 11434 and the third portion 11436 are located on the same side of the second portion 11435, the second portion 11435 and the fourth portion 11437 are located on the same side of the third portion 11436, the third portion 11436 and the fifth portion 11438 are located on the fourth portion 11437. same side; the first part 11434 and the third part 11436 are sleeved on one side of the mounting member 115, and the third part 11436 and the fifth part 11438 are sleeved on the other side of the mounting member 115, wherein the extension direction of the first part 11434, the extension direction of the second part 11435, the extension direction of the third part 11436, the extension direction of the fourth part 11437 and the extension direction of the fifth part 11438 are all parallel to the extension direction of the mounting member 115.

[0063] It can be understood that the first portion 11434 and the third portion 11436 are sleeved on one side of the mounting member 115, and the third portion 11436 and the fifth portion 11438 are sleeved on the other side of the mounting member 115, so as to realize the connection between the mounting member 115 and the sliding member 1142. In addition, the extension direction of the first portion 11434, the extension direction of the second portion 11435, the extension direction of the third portion 11436, the extension direction of the fourth portion 11437 and the extension direction of the fifth portion 11438 are all parallel to the extension direction of the mounting member 115, so that when the second support plate 130 rotates relative to the first support plate 120, the sliding member 1142 can be connected to the mounting member 115 along the sliding direction.

[0064] It can be understood that the first sliding groove 11431 is arranged on the third part 11436.

[0065] In some embodiments, the mounting member 115 includes a mounting body 1154 and a protrusion 1155, wherein the protrusion 1155 is protruding from the surface of the mounting body 1154 facing the sliding member 1142, and the mounting body 1154 and the protrusion 1155 enclose the second slide groove 1151, and the protrusion 1155 includes a first limiting portion 1156, an arc portion 1157 and a second limiting portion 1158 connected in sequence along the first direction. The length of the arc portion 1157 in the second direction first gradually increases and then gradually decreases; when the moving member 141 is in the first position 1152, the moving member 141 abuts against the first limiting portion 1156; when the moving member 141 is in the second position 1153, the moving member 141 abuts against the second limiting portion 1158; when the moving member 141 is between the first position 1152 and the second position 1153, the moving member 141 abuts against the arc portion 1157.

[0066] It can be understood that when the moving member 141 is between the first position 1152 and the second position 1153, the moving member 141 is between the first end 11432 and the second end 11433, then the length of the end of the first limiting portion 1156 close to the arc portion 1157 along the second direction is smaller than the length of the end of the arc portion 1157 close to the first limiting portion 1156 along the second direction; the length of the end of the second limiting portion 1158 close to the arc portion 1157 along the second direction is smaller than the length of the end of the arc portion 1157 close to the second limiting portion 1158 along the second direction.

[0067] It can be understood that the surface of the first limiting portion 1156 facing the second slide groove 1151, the surface of the arc portion 1157 facing the second slide groove 1151 and the surface of the second limiting portion 1158 facing the second slide groove 1151 form the side wall of the second slide groove 1151.

When the movable member 141 is in the second position 1153, the movable member 141 abuts against the second limiting portion 1158, the elastic member 142 is in a relaxed state, and the length of the end of the second limiting portion 1158 close to the arc portion 1157 along the second direction is smaller than the length of the end of the arc portion 1157 close to the second limiting portion 1158 along the second direction, thereby preventing the movable member 141 from separating from the second limiting portion 1158 and moving toward the arc portion 1157 without the action of external force, so that the foldable mechanism 100 can maintain a flat state, thereby preventing the first support plate 120 and the second support plate 130 from suddenly folding and affecting the user experience. When the movable member 141 abuts against the arc portion 1157 during the movement from the first position 1152 to the second position 1153 or from the second position 1153 to the first position 1152, the length between the movable member 141 and the fixed column 1144 first decreases and then gradually increases, and the elastic member 142 is always in a compressed state and is first compressed and then gradually elastically recovered during the movement. During the switching process between the first position 1152 and the second position 1153, the moving member 141 realizes the relative sliding of the sliding member 1142 and the mounting member 115. The sliding member 1142, the moving member 141, the elastic member 142 and the mounting member 115 cooperate with each other to increase the torque during the relative sliding process between the sliding member 1142 and the mounting member 115. On the one hand, the vibration during the sliding process between the sliding member 1142 and the mounting member 115 can be reduced, the relative sliding stability between the second rotating shaft bracket 114 and the second supporting plate 130 can be improved, and the first supporting plate 120 and the second supporting plate 130 can be prevented from violently colliding during the conversion process between the folding state and the flattened state of the foldable mechanism 100, thereby improving the use performance of the foldable mechanism 100. On the other hand, the relative sliding feel of the second rotating shaft bracket 114 and the second supporting plate 130 can be improved, that is, the switching feel of the foldable mechanism 100 between the folding state and the flattened state can be improved, which is conducive to improving the user experience.

[0069] In some embodiments, the bracket body 1141 has an avoidance hole 11411 , and the orthographic projections of the first slide groove 11431 and the fixing column 1144 on the surface of the bracket body 1141 facing the sliding member 1142 fall within the range of the avoidance hole 11411 .

[0070] It can be understood that the orthographic projection of the damping subassembly 140 on the surface of the bracket body 1141 facing the sliding member 1142 falls within the range of the avoidance hole 11411 .

[0071] It can be understood that the avoidance hole 11411 passes through two opposite surfaces of the bracket body 1141 .

[0072] In this embodiment, the bracket body 1141 has an avoidance hole 11411, and the orthographic projections of the first slide groove 11431 and the fixed column 1144 on the surface of the bracket body 1141 facing the sliding member 1142 fall within the range of the avoidance hole 11411, thereby preventing the bracket body 1141 from interfering with the moving member 141, the fixed column 1144 and the elastic member 142, thereby making the relative sliding of the second rotating shaft bracket 114 and the mounting member 115 smoother, thereby improving the efficiency of the foldable mechanism 100 in switching between the folded state and the flattened state.

[0073] In some embodiments, the first limiting portion 1156 includes a connected first limiting sub-portion 11561 and a first blocking sub-portion 11562, the end of the first limiting sub-portion 11561 facing away from the first blocking sub-portion 11562 is connected to the arc portion 1157, and the first blocking sub-portion 11562 is used to block the moving member 141 from separating from the first limiting sub-portion 11561 in a direction away from the arc portion 1157; the second limiting portion 1158 includes a connected second limiting sub-portion 11581 and a second blocking sub-portion 11582, the end of the second limiting sub-portion 11581 facing away from the second blocking sub-portion 11582 is connected to the arc portion 1157, and the second blocking sub-portion 11582 is used to block the moving member 141 from separating from the second limiting sub-portion 11581 in a direction away from the arc portion 1157.

[0074] It can be understood that the first blocking sub-portion 11562, the first limiting sub-portion 11561, the arc portion 1157, the second limiting sub-portion 11581 and the second blocking sub-portion 11582 are connected in sequence.

[0075] It can be understood that the length of the first blocking sub-portion 11562 along the second direction is greater than the length of the first limiting sub-portion 11561 along the second direction, and the length of the second blocking sub-portion 11582 along the second direction is greater than the length of the second limiting sub-portion 11581 along the second direction.

[0076] In the protruding portion 1155 provided in this embodiment, the first blocking sub-portion 11562, the first limiting sub-portion 11561, the arc portion 1157, the second limiting sub-portion 11581 and the second blocking sub-portion 11582 are connected in sequence. When the moving part 141 switches from the first position 1152 to the second position 1153, the moving part 141 enters the second limiting sub-portion 11581 from the arc portion 1157, and the second blocking sub-portion 11582 can prevent the moving part 141 from continuing to disengage from the second limiting sub-portion 11581 in the direction away from the arc portion 1157; when the moving part 141 switches from the second position 1153 to the first position 1152, the moving part 141 enters the first limiting sub-portion 11561 from the arc portion 1157, and the first blocking sub-portion 11562 can prevent the moving part 141 from continuing to disengage from the first limiting sub-portion 11561 in the direction away from the arc portion 1157. The first blocking sub-portion 11562 and the second blocking sub-portion 11582 are conducive to blocking the moving member 141 from continuing to move in the direction away from the arc-shaped portion 1157, so that the moving member 141 is accurately positioned between the first position 1152 and the second position 1153, so that the foldable mechanism 100 can be accurately switched between the folded state and the flattened state, avoiding interference between the first support plate 120 and the second support plate 130.

Compared with the solution in which the side of the arc portion 1157 facing the first blocking sub-portion 11562 is the arc surface 11564, the second plane 11571 increases the resistance of the moving member 141 moving from the first limiting sub-portion 11561 to the arc portion 1157. When the foldable mechanism 100 is in a folded state, in the absence of external force or with little external force, the second plane 11571 can prevent the movable member 141 from separating from the first limiting sub-portion 11561 and entering the arc portion 1157, thereby preventing the first support plate 120 and the second support plate 130 from moving relative to each other or suddenly opening to damage the flexible display screen 210, thereby improving the performance of the foldable mechanism 100.
