Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to a rotating mechanism and a folding terminal. BACKGROUND

[0002] With the improvement of people's demand, folding terminals are more and more concerned and favored by people. The existing folding terminals usually use a rotating mechanism to drive the two bodies to rotate relative to each other to realize the switching between the folded state and the unfolded state. However, when the folding terminal is in the folded state, the shaft cover side of the rotating mechanism is prone to knocking, which causes the shaft cover to deform, and further causes the flexible screen to display abnormally, shortens the service life of the folding terminal, and affects the user experience. SUMMARY

[0003] In order to solve the problem that the flexible screen will display abnormally due to the external force received by the shaft cover after the shaft cover is knocked, the present application provides a rotating mechanism and a folding terminal with good protection performance.

[0004] A first aspect of the present application provides a rotating mechanism. The rotating mechanism includes a first swing arm, a second swing arm, a shaft cover, a shaft support, and a force relief structure. The first swing arm can rotate about a first axis, the second swing arm can rotate about a second axis, the second axis is parallel to the first axis, and the rotation directions of the first swing arm and the second swing arm are opposite. In a first direction, at least a portion of the shaft support is located between the first swing arm and the second swing arm. In a second direction, the shaft cover and the shaft support are provided with a force relief structure, and the force relief structure is used to relieve force when the shaft cover is subjected to an external force.

[0005] For example, the first direction mentioned above can be the X direction mentioned in the embodiments below, and the second direction mentioned above can be the Z direction mentioned in the embodiments below.

[0006] It can be understood that the above rotating structure can be applied to a folding terminal, and the folding terminal can be a folding mobile phone, a tablet personal computer, an electronic book reader, a laptop computer, a personal digital assistant (PDA), a personal computer, a notebook computer, a vehicle-mounted device, a wearable device (such as a watch), a box, and other electronic devices that need to be opened and closed synchronously.

[0007] That is, in the embodiments of the present application, the rotating mechanism comprises a first swing arm, a second swing arm, a shaft support, a shaft cover and a force relief structure. The first swing arm rotates in the A direction mentioned in the embodiments below, and the second swing arm rotates in the B direction mentioned in the embodiments below. The shaft support comprises a base and a support portion on the surface of the base. Exemplarily, the base and the support portion jointly form a shape similar to an inverted "T". In the first direction, the support portion is located between the first swing arm and the second swing arm. In the second direction, the shaft cover is arranged on the surface of the base away from the support portion, and the force relief structure is arranged between the shaft support and the shaft cover, and the force relief structure can buffer the force when the shaft cover is subjected to external force.

[0008] The rotating mechanism described above can buffer the force when the shaft cover is subjected to external force while achieving the folding function, thereby avoiding damage to the flexible screen due to stress concentration, effectively improving the durability of the folding terminal, and providing a good user experience. In addition, the rotating mechanism described above has a simple and compact structure, low cost and wide application range.

[0009] In some possible implementation manners of the first aspect, the force relief structure comprises an elastic arm, and the elastic arm is arranged on a first surface of the shaft support facing the shaft cover. In the Y direction mentioned in the embodiments below, the size of the elastic arm is equal to the size of the first surface.

[0010] In some possible implementation manners of the first aspect, the elastic arm comprises a first elastic arm and a second elastic arm, and in the first direction, two ends of the first surface of the shaft support are respectively bent to form the first elastic arm and the second elastic arm, and the first elastic arm and the second elastic arm are respectively bent in the first direction and are arranged in the second direction to be spaced apart from the first surface.

[0011] That is, in the embodiments of the present application, the first end of the first surface of the shaft support is bent in the C direction mentioned in the embodiments below, thereby forming the first elastic arm. The second end of the first surface of the shaft support is bent in the D direction mentioned in the embodiments below, thereby forming the second elastic arm. In the second direction, there is a gap between the first elastic arm and the second elastic arm and the first surface.

[0012] Under the protection of the first elastic arm and the second elastic arm, when the shaft cover collides, the shaft cover will not continue to transmit the external force to the shaft support, and therefore the shaft support will not collide with the flexible screen due to the force, thereby avoiding the problem of damage to the flexible screen due to collision.

[0013] In some possible implementation manners of the first aspect, the elastic arm comprises a third elastic arm and a fourth elastic arm, and in the first direction, two ends of the first surface of the shaft support are respectively bent away from each other to form the third elastic arm and the fourth elastic arm, and the third elastic arm and the fourth elastic arm are respectively extended in the first direction and are arranged in the second direction to be spaced apart from the first surface.

[0014] That is, in the embodiments of the present application, the third elastic arm and the fourth elastic arm are arranged between the first end and the second end of the first surface. Exemplarily, in the first direction, the first surface is bent in a manner of bending away from the middle region of the support portion, thereby forming the third elastic arm and the fourth elastic arm. That is, the middle region of the first surface of the shaft support member is bent in the direction D mentioned in the embodiments below, thereby forming the third elastic arm, and the middle region of the first surface of the shaft support member is bent in the direction C mentioned in the embodiments below, thereby forming the fourth elastic arm. In the first direction, there is a gap between the third elastic arm and the fourth elastic arm and the first surface.

[0015] Based on this, the contact area between the shaft support member, the shaft cover and the elastic arm can be further expanded, so that the elastic arm can withstand greater external force impact.

[0016] In some possible implementation ways of the first aspect, the elastic arm comprises a fifth elastic arm, in the first direction, the two ends of the first surface of the shaft support member are bent respectively to form the fifth elastic arm, and the fifth elastic arm extends in the first direction and surrounds a hollow annular structure with the first surface.

[0017] That is, in the embodiments of the present application, the first end of the first surface of the shaft support member is bent in the direction C mentioned in the embodiments below, and the second end of the first surface of the shaft support member is bent in the direction D mentioned in the embodiments below, thereby forming the fifth elastic arm. The fifth elastic arm surrounds a hollow annular structure with the first surface of the shaft support member.

[0018] Based on this, the shaft support member and the shaft cover can be elastically connected, and when the shaft cover is impacted, the fifth elastic arm can be deformed and buffer the force, thereby protecting the folding screen. Moreover, the hollow annular structure of the fifth elastic arm makes the contact area between the fifth elastic arm and the shaft support member larger, and the fifth elastic arm can withstand external force impact from all directions.

[0019] In some possible implementation ways of the first aspect, the first direction and the second direction are perpendicular.

[0020] In some possible implementation ways of the first aspect, the material of the elastic arm and the shaft support member is metal.

[0021] In some possible implementation ways of the first aspect, the force relief structure comprises an elastic support pad arranged on the first surface of the shaft support member facing the shaft cover. In the Y direction mentioned in the embodiments below, the size of the elastic support pad is equal to the size of the first surface.

[0022] In some possible implementation manners of the first aspect, the elastic support pad comprises a first elastic support pad and a second elastic support pad, the first elastic support pad and the second elastic support pad are arranged at intervals along the first direction and are respectively injection molded with the first surface and the surface of the shaft cover facing the first surface.

[0023] The first elastic support pad and the second elastic support pad are arranged at intervals along the first direction on the first surface of the shaft support. For example, the first elastic support pad is arranged on the first surface close to the first end, and the second elastic support pad is arranged on the first surface close to the second end.

[0024] The first elastic support pad and the second elastic support pad can realize elastic connection between the shaft support and the shaft cover. When the shaft cover is subjected to external force, the first elastic support pad and the second elastic support pad are elastically deformed, thereby playing a role of impact buffering.

[0025] In some possible implementation manners of the first aspect, the elastic support pad comprises a first elastic support pad and a second elastic support pad, the first elastic support pad and the second elastic support pad are arranged at intervals along the first direction and are respectively injection molded with the first surface and the surface of the shaft cover facing the first surface.

[0026] In some possible implementation manners of the first aspect, the elastic support pad has a hollow ring shape and extends along the first direction, and the elastic support pad is injection molded with the first surface and the surface of the shaft cover facing the first surface.

[0027] Based on this, the contact area between the shaft support, the shaft cover and the elastic support pad can be further increased, so that the buffering and releasing force of the elastic support pad is further enhanced, and the elastic support pad can withstand greater external force.

[0028] In some possible implementation manners of the first aspect, the material of the elastic support pad is plastic, and the material of the shaft support and the shaft cover is metal.

[0029] In some possible implementation manners of the first aspect, a plurality of glue pulling grooves are arranged on the region of the first surface of the shaft support in contact with the elastic support pad, the plurality of glue pulling grooves are arranged at intervals along the first direction on the first surface and extend along the Y direction mentioned in the subsequent embodiments. When the first surface of the shaft support is injection molded with the elastic support pad, the glue pulling grooves of the shaft support enable the plastic material (i.e., the material used to form the elastic support pad) to form a part that can be embedded in the first surface, so that the injection is sufficient, and the bonding force between the shaft support and the elastic support pad is further improved.

[0030] In some possible implementation manners of the first aspect, the first surface of the shaft support member is provided with a pull-out groove at a region in contact with the elastic support pad, and the second surface of the shaft cover is also provided with a pull-out groove at a region in contact with the elastic support pad. The shaft support member and the shaft cover are engaged with the elastic support pad in a bite manner through the pull-out grooves, further increasing the contact area and the binding force among the shaft support member, the shaft cover and the elastic support pad, effectively improving the anti-pulling ability of the elastic support pad, and further improving the durability of the rotating mechanism. In addition, the pull-out groove also plays a positioning role, improving the position accuracy among the shaft support member, the shaft cover and the elastic support pad.

[0031] In some possible implementation manners of the first aspect, the force relief structure includes a groove, and the groove is arranged on the second surface of the shaft cover facing the shaft support member.

[0032] In some possible implementation manners of the first aspect, the groove includes a plurality of grooves, each groove extends along the third direction, and the plurality of grooves are arranged in the first direction.

[0033] For example, the third direction can be the Y direction mentioned in the embodiments below.

[0034] When the shaft cover is deformed by external force, the plurality of grooves relieve the external force to the shaft cover, and based on this, the shaft cover will not continue to transmit the received external force to the shaft support member.

[0035] In some possible implementation manners of the first aspect, the groove includes a plurality of grooves, and a projection of each groove along the second direction is in a V shape, and the plurality of grooves are arranged in parallel.

[0036] Each groove includes a first side and a second side, and the first side and the second side jointly form a V-shaped structure, that is, the projection of each groove along the second direction is in a V shape. The plurality of grooves are arranged in parallel, that is, the first sides of the plurality of grooves are parallel to each other, and the second sides of the plurality of grooves are parallel to each other. The groove can withstand external force in multiple directions, further improving the force relief effect.

[0037] The second aspect of the present application provides a folding terminal, which includes a first body, a second body and the rotating mechanism in the first aspect and any possible implementation manner of the first aspect. The first swing arm in the rotating mechanism is connected to the first body, and the second swing arm in the rotating mechanism is connected to the second body.

[0038] In some possible implementations of the second aspect mentioned above, the foldable terminal also includes a flexible screen, which covers the first body, the second body, and the shaft support. The first body and the second body rotate relative to each other via a rotating mechanism, which in turn drives the flexible screen to move, causing it to be in a bent or unfolded state, thereby allowing the foldable terminal to switch between these states.

Detailed Implementation

[0053] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0054] This application provides a rotating mechanism that can be applied to foldable terminals. Specifically, the foldable terminal includes, but is not limited to, foldable mobile phones, tablet personal computers, e-book readers, laptop computers, personal digital assistants (PDAs), personal computers, notebooks, in-vehicle devices, wearable devices (such as watches), set-top boxes, and other electronic devices that require synchronized opening and closing.

[0055] For ease of explanation, the following description uses a foldable mobile phone as an example of a foldable terminal. The foldable mobile phone of this application will be introduced below with specific embodiments.

[0056] Figure 1 (a) shows a schematic diagram of the unfolded state of a foldable mobile phone according to an embodiment of this application. Figure 1 (b) shows a schematic diagram of the folded state of a foldable mobile phone according to an embodiment of this application.

[0057] For ease of subsequent description, before describing the specific structure of the foldable phone 1, this application will first combine... Figure 1 (a) and Figure 1 (b) Define the X direction (as the first direction), Z direction (as the second direction), and Y direction (as the third direction). For example... Figure 1 (a) and Figure 1(b), the X direction is the length direction of the folding mobile phone 1, wherein the length direction can be the length direction of the flexible screen 400 (mentioned below), and can also be understood as the direction held by the user; the Y direction is the width direction of the folding mobile phone 1, wherein the width direction can be the width direction of the flexible screen 400, and can also be understood as the direction perpendicular to the direction held by the user in the plane of the flexible screen 400; and the Z direction is the thickness direction of the folding mobile phone 1. The X direction, the Y direction and the Z direction are perpendicular to each other in pairs, and are exemplarily described below.

[0058] In combination with Figure 1 (a) and Figure 1 (b), the folding mobile phone 1 comprises a rotating mechanism 100, a first body 200, a second body 300 and a flexible screen 400. In the X direction, the first body 200 and the second body 300 are respectively arranged on opposite sides of the rotating mechanism 100, and the first body 200 and the second body 300 are respectively connected with the rotating mechanism 100 and can rotate relative to each other. Exemplarily, the first body 200 and the second body 300 are internally provided with electronic components such as a battery, a control circuit board and the like.

[0059] The flexible screen 400 is fixed on the first body 200 and the second body 300, and exemplarily, the rotating mechanism 100, the first body 200 and the second body 300 are covered by the flexible screen 400. The first body 200 and the second body 300 rotate relative to each other through the rotating mechanism 100, and can drive the flexible screen 400 to move, so that the flexible screen 400 presents a curved state or an unfolded state, thereby enabling the folding mobile phone 1 to switch between a folded state and an unfolded state.

[0060] Figure 2 (a) shows a schematic view of the rotating mechanism when the folding mobile phone is in the folded state in some embodiments. Figure 2 (b) shows a perspective view of the rotating mechanism when the folding mobile phone is in the unfolded state in some embodiments. In combination with Figure 2 (a) and Figure 2 (b), in some technical solutions, the rotating mechanism 100a comprises a first swing arm 110, a second swing arm 120, a shaft support 130 and a shaft cover 140. In the X direction, the first swing arm 110 and the second swing arm 120 are respectively arranged on opposite sides of the shaft support 130, and can also be understood as, in the X direction, at least a part of the shaft support 130 is located between the first swing arm 110 and the second swing arm 120. In the Z direction, the shaft support 130 is arranged on the surface of the shaft cover 140, and exemplarily, the shaft support 130 is connected with the shaft cover 140 through a screw, or the shaft support 130 is fixedly connected with the shaft cover 140 through spot welding, which is not limited in the present application.

[0061] In the folding mobile phone 1 described above, the first swing arm 110 is connected with the first body 200 and can drive the first body 200 to move; the second swing arm 120 is connected with the second body 300 and can drive the second body 300 to move. Through the movement of the first swing arm 110 and the second swing arm 120, the relative rotation of the first body 200 and the second body 300 can be realized, so that the first body 200 and the second body 300 drive the flexible screen 400 to move, the flexible screen 400 can be dynamically switched between the curved state and the unfolded state, and then the folding mobile phone 1 can be dynamically switched between the folded state and the unfolded state, realizing the folding function of the folding mobile phone 1. Exemplarily, when the folding mobile phone 1 is in the folded state, the flexible screen 400 will be curved, as shown in Figure 2 (a), the curved flexible screen 400 is similar to a "U" shape. When the folding mobile phone 1 is in the unfolded state, the flexible screen 400 will be unfolded, as shown in Figure 2 (b), at this time, the first swing arm 110 and the second swing arm 120 of the rotating mechanism 100a are similar to a "I" shape, so that the flexible screen (not shown in the figure) is in an unfolded state.

[0062] When the folding mobile phone 1 is in the folded state, the shaft cover 140 is prone to being knocked, thereby damaging the flexible screen 400. For example Figure 3 the folding mobile phone force diagram is shown. In combination with Figure 2 (a) and Figure 3 , it can be known that when the shaft cover 140 is subjected to an external force at the P1 point position, Figure 2 (a), the shaft cover 140 will be deformed, for example Figure 3 , the shaft cover 140 is recessed to one side of the shaft support 130, the deformed shaft cover 140 transmits the external force to the shaft support 130, the shaft support 130 is subjected to the external force and hits the flexible screen 400, causing the flexible screen 400 to be damaged and unable to normally display images, affecting the user experience.

[0063] To solve the above problems, the application provides a rotating mechanism, which comprises a force relief structure and can be buffered and relieved, thereby avoiding the above-mentioned problem of damage to the flexible screen caused by knocking, and further improving the service life and user experience of the folding mobile phone 1, which will be described in detail below in combination with the drawings.

[0064] Figure 4 A perspective view of the rotating mechanism in some embodiments of the application is shown. As shown in Figure 4 , the rotating mechanism 100 comprises a first swing arm 110, a second swing arm 120, a shaft support 130, a shaft cover 140 and a force relief structure 150.

[0065] Among them, the first swing arm 110 can rotate around the first axis (indicated by the dashed line L1 in Figure 4 , the second swing arm 120 can rotate around the second axis (Figure 4 The first axis and the second axis are parallel, and the rotation direction of the first swing arm 110 (indicated by the A direction in FIG. 11) is opposite to the rotation direction of the second swing arm 120 (indicated by the B direction in FIG. 11). Figure 4 Figure 4

[0066] Figure 5 A perspective view of the shaft support in some embodiments of the present application is shown. As can be seen from Figure 4 and Figure 5 The shaft support 130 includes a base 131 and a support portion 132. The support portion 132 is arranged on the surface of the base 131. For example, the base 131 and the support portion 132 jointly form a shape similar to an inverted "T". At least a portion of the shaft support 130 is located between the first swing arm 110 and the second swing arm 120 along the X direction. For example, the support portion 132 of the shaft support 130 is located between the first swing arm 110 and the second swing arm 120 along the X direction.

[0067] As can be seen from Figure 4 and Figure 5 The shaft cover 140 is arranged on the surface of the base 131 away from the support portion 132 along the Z direction. For the convenience of the following description, the surface of the base 131 away from the support portion 132 is defined as a first surface 133, and the surface of the shaft cover 140 facing the first surface 133 is defined as a second surface 141. It can be understood that the first surface 133 and the second surface 141 are two opposite surfaces along the Z direction.

[0068] The force relief structure 150 is arranged between the shaft support 130 and the shaft cover 140 along the Z direction, and the force relief structure 150 can buffer the force when the shaft cover 140 is subjected to an external force.

[0069] In some embodiments, the force relief structure 150 is an elastic arm structure. As shown in Figure 5 The force relief structure 150 is located on the side of the first surface 133 of the shaft support 130 and extends along the Y direction. For example, the size of the force relief structure 150 is equal to the size of the first surface 133 along the Y direction.

[0070] The force relief structure 150 includes a first elastic arm 151 and a second elastic arm 152. The first end 1331 and the second end 1332 of the first surface 133 are bent in a way of bending towards each other along the X direction, so as to form the first elastic arm 151 and the second elastic arm 152. That is, the first end 1331 of the first surface 133 of the shaft support 130 is bent along the positive direction of the X (indicated by the C direction in FIG. 11), so as to form the first elastic arm 151. The second end 1332 of the first surface 133 of the shaft support 130 is bent along the negative direction of the X (indicated by the D direction in FIG. 11), so as to form the second elastic arm 152. Figure 5 Figure 5 ​​​The first elastic arm 151 is bent along the positive direction of the X axis, and the second elastic arm 152 is bent along the negative direction of the X axis. In the Z direction, the first elastic arm 151 and the second elastic arm 152 are respectively arranged away from the first surface 133 of the shaft support 130, that is, there is a gap between the first elastic arm 151 and the second elastic arm 152 and the first surface 133 in the Z direction.

[0071] The first elastic arm 151 is bent along the positive direction of the X axis, and the second elastic arm 152 is bent along the negative direction of the X axis. In the Z direction, the first elastic arm 151 and the second elastic arm 152 are respectively arranged away from the first surface 133 of the shaft support 130, that is, there is a gap between the first elastic arm 151 and the second elastic arm 152 and the first surface 133 in the Z direction.

[0072] When the shaft cover 140 is subjected to an external force, the first elastic arm 151 and the second elastic arm 152 can play a role in buffering and protecting the force.

[0073] Figure 6 (a) and Figure 6 (b) shows a schematic diagram of the elastic arm force relief in some embodiments of the present application. In combination with Figure 6 (a) and Figure 6 (b), when the P2 position of the shaft cover 140 is subjected to an external force, the shaft cover 140 will be deformed from the state shown in Figure 6 (a) to the state shown in Figure 6 (b). As shown in Figure 6 (b), the shaft cover 140 is recessed towards the side of the shaft support 130, at this time, the second elastic arm 152 arranged between the shaft support 130 and the shaft cover 140 buffers the force. In other embodiments, the area of the shaft cover 140 close to the first elastic arm 151 is subjected to an external force, at this time, the first elastic arm 151 arranged between the shaft support 130 and the shaft cover 140 buffers the force. Or, in other embodiments, the shaft cover 140 is subjected to external force in multiple directions at the same time, at this time, the first elastic arm 151 and the second elastic arm 152 simultaneously buffer the force. Under the protection of the first elastic arm 151 and the second elastic arm 152, the shaft cover 140 will not continue to transmit the external force to the shaft support 130, and therefore the shaft support 130 will not hit the flexible screen 400 due to the force, thereby avoiding the problem of damage to the flexible screen 400 due to bumps.

[0074] Based on this, the rotation mechanism 100 of the present application can effectively protect the flexible screen 400 from being damaged while realizing the folding function through the use of the force relief structure 150, thereby prolonging the service life of the folding mobile phone 1 and improving the user experience.

[0075] There are various ways for the force relief structure 150 to relieve force and corresponding structural setting schemes, which will be further introduced in combination with the drawings.

[0076] In an implementable scheme, in addition to the first elastic arm 151 and the second elastic arm 152 described above, the force relief structure 150 can also have other forms of elastic arms. Figure 7(a) and Figure 7 (b) shows the schematic diagram of several elastic arms in this application.

[0077] In some embodiments, as shown in Figure 7 (a), in addition to the first elastic arm 151 and the second elastic arm 152 described above, the force relief structure 150 further includes a third elastic arm 153 and a fourth elastic arm 154.

[0078] Wherein, Figure 7 The first elastic arm 151 and the second elastic arm 152 in (a) are formed in the same way as the first elastic arm 151 and the second elastic arm 152 in (b), which will not be repeated here. Figure 5 The first elastic arm 151 and the second elastic arm 152 in (a) are formed in the same way as the first elastic arm 151 and the second elastic arm 152 in (b), which will not be repeated here.

[0079] The third elastic arm 153 and the fourth elastic arm 154 are arranged between the first end 1331 and the second end 1332 of the first surface 133. Exemplarily, along the X direction, the first surface 133 is close to the middle region of the support part 132 (for example Figure 7 the P3 position and the P4 position in (a)), and is bent in a back-to-back manner, thereby forming the third elastic arm 153 and the fourth elastic arm 154. That is, the P3 position of the first surface 133 of the shaft support 130 is bent along the X negative direction (as shown by the D direction in (a)), thereby forming the third elastic arm 153, and the P4 position of the first surface 133 of the shaft support 130 is bent along the X positive direction (as shown by the C direction in (a)), thereby forming the fourth elastic arm 154. Figure 7 the P3 position and the P4 position in (a)), and is bent in a back-to-back manner, thereby forming the third elastic arm 153 and the fourth elastic arm 154. That is, the P3 position of the first surface 133 of the shaft support 130 is bent along the X negative direction (as shown by the D direction in (a)), thereby forming the third elastic arm 153, and the P4 position of the first surface 133 of the shaft support 130 is bent along the X positive direction (as shown by the C direction in (a)), thereby forming the fourth elastic arm 154. Figure 7 the P3 position and the P4 position in (a)), and is bent in a back-to-back manner, thereby forming the third elastic arm 153 and the fourth elastic arm 154. That is, the P3 position of the first surface 133 of the shaft support 130 is bent along the X negative direction (as shown by the D direction in (a)), thereby forming the third elastic arm 153, and the P4 position of the first surface 133 of the shaft support 130 is bent along the X positive direction (as shown by the C direction in (a)), thereby forming the fourth elastic arm 154.

[0080] The third elastic arm 153 is bent along the X negative direction, and the fourth elastic arm 154 is bent along the X positive direction. Along the Z direction, the third elastic arm 153 and the fourth elastic arm 154 are respectively arranged spaced apart from the first surface 133 of the shaft support 130, that is, along the Z direction, there is a gap between the third elastic arm 153 and the fourth elastic arm 154 and the first surface 133.

[0081] The force relief structure 150 described above includes the first elastic arm 151, the second elastic arm 152, the third elastic arm 153 and the fourth elastic arm 154, which further expands the contact area between the shaft support 130, the shaft cover 140 and the force relief structure 150, so that the force relief structure 150 can withstand greater external force impact.

[0082] In other embodiments, as shown in Figure 7 (b), the force relief structure 150 includes a fifth elastic arm 155. Specifically, the first end 1331 of the first surface 133 of the shaft support 130 is bent along the X positive direction (as shown by the D direction in (b)), thereby forming the fifth elastic arm 155. Figure 7(b) shown in the direction of C) is bent, the second end 1332 of the first surface 133 of the shaft support 130 is bent in the direction of X negative (X- Figure 7 (b) shown in the direction of D) is bent, thereby forming the fifth elastic arm 155. The fifth elastic arm 155 cooperates with the first surface 133 of the shaft support 130 to form a hollow annular structure.

[0083] Based on this, the shaft support 130 and the shaft cover 140 can be elastically connected. When the shaft cover 140 is impacted, the fifth elastic arm 155 can be deformed and buffer the force, thereby protecting the folding screen 400. The hollow annular structure of the fifth elastic arm 155 makes the contact area between the fifth elastic arm 155 and the shaft support 130 larger, and the fifth elastic arm 155 can withstand external force impact from all directions.

[0084] In some embodiments, the shaft support 130 and the elastic arm 150 are both made of metal.

[0085] In another implementable solution, the force relief structure 150 is an elastic support pad. Figure 8 (a) Figure 8 (c) shows the schematic diagram of several elastic support pads in the present application. In combination with 8(a) Figure 8 (c), it can be seen that the force relief structure 150 includes an elastic support pad 156, which is arranged on the first surface 133 of the shaft support 130 and extends in the Y direction. In the Y direction, the size of the elastic support pad 156 is equal to the size of the first surface 133.

[0086] In some embodiments, as shown in Figure 8 (a), the elastic support pad 156 includes a first elastic support pad 1561 and a second elastic support pad 1562. In the X direction, the first elastic support pad 1561 and the second elastic support pad 1562 are arranged on the first surface 133 of the shaft support 130 with a certain interval. For example, the first elastic support pad 1561 is arranged on the region of the first surface 133 close to the first end 1331, and the second elastic support pad 1562 is arranged on the region of the first surface 133 close to the second end 1332.

[0087] Exemplarily, in some of the implementations, as shown in Figure 8 (a), the first elastic support pad 1561 is injection molded with the first surface 133 of the shaft support 130; and the second elastic support pad 1562 is injection molded with the first surface 133 of the shaft support 130.

[0088] Figure 9 The schematic diagram of the rotating mechanism with an elastic support pad in some embodiments of the present application is shown. As shown in Figure 9As shown, in the rotating mechanism 100, the first elastic support pad 1561 and the second elastic support pad 1562 can realize the elastic connection between the shaft support 130 and the shaft cover 140. When the shaft cover 140 is subjected to external force, the first elastic support pad 1561 and the second elastic support pad 1562 will undergo elastic deformation, thereby playing the role of impact buffering.

[0089] In some other implementations, such as 8(b), the first elastic support pad 1561 is injection molded to the first surface 133 of the shaft support 130 and the second surface 141 of the shaft cover 140; the second elastic support pad 1562 is injection molded to the first surface 133 of the shaft support 130 and the second surface 141 of the shaft cover 140, so that the shaft support 130, the shaft cover 140, the first elastic support pad 1561 and the second elastic support pad 1562 are integrated into one unit.

[0090] In other embodiments, such as Figure 8 As shown in (c), the elastic support pad 156 is a hollow annular shape. The elastic support pad 156 is in contact with the first surface 133 of the shaft support member 130 and the second surface 141 of the shaft cover 140, respectively, and the elastic support pad 156 extends in the X direction. Exemplarily, the elastic support pad 156 is injection molded with the first surface 133 of the shaft support member 130 and the second surface 141 of the shaft cover 140, so that the shaft support member 130, the shaft cover 140 and the elastic support pad 156 are integrated into one piece.

[0091] Based on this, the contact area between the shaft support 130, the shaft cover 140 and the elastic support pad 156 can be further increased, thereby further enhancing the buffering and stress relief capacity of the elastic support pad 156 and enabling the elastic support pad 156 to withstand greater external forces.

[0092] In some embodiments, the shaft support 130 and the shaft cover 140 are made of metal, and the elastic support pad 156 is made of plastic.

[0093] In some embodiments, multiple adhesive grooves are formed in the area where the first surface 133 of the shaft support 130 contacts the elastic support pad 156, for example... Figure 8 The adhesive groove 134 shown in (a) is as follows: Figure 8 As shown in (a), the pull grooves 134 are spaced apart along the X direction on the first surface 133 and extend along the Y direction. During injection molding of the first surface 133 of the shaft support 130 and the elastic support pad 156, the pull grooves 134 of the shaft support 130 cause the plastic material (i.e., the material used to form the elastic support pad 156) to form a portion that can be embedded in the first surface 133, so as to ensure sufficient injection molding and further enhance the bonding force between the shaft support 130 and the elastic support pad 156.

[0094] In some embodiments, the first surface 133 of the shaft support 130 is provided with a pull-out groove 134 at the area where the elastic support pad 156 is in contact with the first surface 133, and the second surface 141 of the shaft cover 140 is also provided with a pull-out groove 142 at the area where the elastic support pad 156 is in contact with the second surface 141, for example Figure 8 (b) and Figure 8 (c) show the pull-out groove 134 and the pull-out groove 142. As shown in Figure 8 (b) and Figure 8 (c), the shaft support 130 is engaged with the elastic support pad 156 in a bite-like manner through the pull-out groove 134, and the shaft cover 140 is engaged with the elastic support pad 156 in a bite-like manner through the pull-out groove 144, which further increases the contact area and the bonding force among the shaft support 130, the shaft cover 140 and the elastic support pad 156, effectively improving the anti-pulling ability of the elastic support pad 156, and further improving the durability of the rotating mechanism 100. In addition, the pull-out groove 134 and the pull-out groove 142 also play a positioning role, improving the positional accuracy among the shaft support 130, the shaft cover 140 and the elastic support pad 156.

[0095] In another implementation scheme, the force relief structure 150 is a groove structure. Figure 10 (a) and Figure 10 (b) show the schematic diagrams of several grooves in the present application. As shown in Figure 10 (a) and (b), the force relief structure 150 includes a plurality of grooves 157, and the plurality of grooves 157 are provided on the second surface 141 of the shaft cover 140.

[0096] Figure 8 (a) shows that each groove 157 extends along the Y direction, and the plurality of grooves 157 are arranged at intervals along the X direction.

[0097] Figure 11 show the schematic diagrams of the rotating mechanism with the groove structure in some embodiments of the present application. As shown in Figure 11 In the rotating mechanism 100, the second surface 141 of the shaft cover 140 is provided with a plurality of grooves 157, and when the shaft cover 140 is deformed by external force, the plurality of grooves 157 relieve the external force to the shaft cover 140, based on which the shaft cover 140 will not continue to transmit the received external force to the shaft support 130.

[0098] In another implementation scheme, as shown in Figure 8(b) As shown, each groove 157 includes a first side 1571 and a second side 1572, which together form a "V" shape, that is, the projection of each groove 157 in the Z direction is in the shape of a "V". The plurality of grooves 157 are arranged parallel to each other, that is, the first sides 1571 of the plurality of grooves 157 are parallel to each other, and the second sides 1572 of the plurality of grooves 157 are parallel to each other. The grooves 157 can withstand external forces in multiple directions, further improving the force relief effect.

[0099] It can be understood that any shape of the grooves 157 that can achieve the above-mentioned force relief effect is within the scope of protection of the present application, and the present application does not specifically limit it.

[0100] In summary, the rotating mechanism of the embodiments of the present application adopts a force relief structure that can buffer and relieve force when the shaft cover is subjected to external force, thereby avoiding damage to the flexible screen due to stress concentration and effectively improving the durability of the folding mobile phone, providing a good user experience. In addition, the rotating mechanism of the present application is simple and compact in structure, low in cost, and has a wide range of applications.
