The first supporting member 111 is connected to the main body 120 through a first rotating mechanism 130, and the second supporting member 111' is connected to the main body 120 through a second rotating mechanism 130'. When the folding device 100 is in a flat state, the first supporting member 111 and the second supporting member 111' are respectively disposed on both sides of the main body 120. The first rotating mechanism 130 and the second rotating mechanism 130' are arranged symmetrically or asymmetrically with respect to the main body 120. When the first rotating mechanism 130 and the second rotating mechanism 130' are arranged symmetrically with respect to the main body 120, the first rotating mechanism 130 and the second rotating mechanism 130' may be arranged symmetrically along the axis of the main body 120. In this embodiment and the schematic diagram of this embodiment, the first rotating mechanism 130 and the second rotating mechanism 130' are arranged symmetrically along the axis of the main body 120, which should not be understood as limiting the folding device 100 provided in the present application.

The cooperative relationship between the second rotating mechanism 130' and the main body 120 is the same as the cooperative relationship between the first rotating mechanism 130 and the main body 120. The cooperation relationship between the second rotation mechanism 130' and the second support member 111' is the same as the cooperation relationship between the first rotation mechanism 130 and the first support member 111. The following mainly introduces the example of the first rotating mechanism 130 cooperating with the main body 120 and the first support member 111 respectively. It is known that between each component in the first rotating mechanism 130 (the first rotating member 131, the second rotating member 132, the third rotating member 133 and the connecting member 134), the main body 120 and the first supporting member 111 Under the premise of the matching relationship, each component of the first rotating mechanism 130 can be replaced with the same component of the second rotating mechanism 130', and the first supporting member 111 can be replaced with the second supporting member 111' to obtain the above-mentioned Cooperation between each component of the second rotating mechanism 130' (the first rotating member 131, the second rotating member 132, the third rotating member 133 and the connecting member 134), the main body 120 and the second supporting member 111' relation.

The connection relationship between the first rotating member 131 , the second rotating member 132 , the third rotating member 133 and the connecting member 134 in the first rotating mechanism 130 with the main body 120 and the first supporting member 111 will be introduced below.

The folding device 100 is located between the two housings 500. The two housings 500 are respectively connected to the connecting piece 134 of the first rotating mechanism 130 and the second rotating mechanism 130' of the folding device 100. When the connecting piece 134 of the first rotating mechanism 130 and the connecting piece 134 of the second rotating mechanism 130' rotate, the two housings 500 rotate to switch between the unfolded state and the folded state. It should be noted that this application does not limit the rotation of the two housings 500, the active and passive relationships, and the timing of the rotation of the connecting piece 134 of the first rotating mechanism 130 and the connecting piece 134 of the second rotating mechanism 130'.

In one embodiment, the connecting member 134 may be fixed to the housing 500 so that the connecting member 134 rotates when the housing 500 rotates. The connecting member 134 and the housing 500 may have an integrated structure or a split structure. When the connector 134 and the housing 500 are of an integrated structure, the connector 134 and the housing 500 can be prepared through one process. However, for ease of understanding, the connector 134 and the housing 500 are artificially named differently. When the connector 134 and the housing 500 have a split structure, the connector 134 and the housing 500 are two independent components, and the connector 134 is fixed by various methods such as bonding, screw connection, snap connection, etc. on the housing 500. This embodiment is only schematically described using the connector 134 and the housing 500 as separate structures. It can be understood that the connection method between the connecting piece 134 in the first rotating mechanism 130 and one housing 500 can be the same as the connecting method between the connecting piece 134 in the second rotating mechanism 130' and another housing 500. It can also be different.

One end of the first rotating member 131 of the first rotating mechanism 130 is rotationally connected to the main body 120 , and the other end is slidingly connected to the first supporting member 111 . Correspondingly, one end of the first rotating member 131 of the second rotating mechanism 130' is rotationally connected to the main body 120, and the other end is slidingly connected to the second supporting member 111'. Therefore, when the folding device 100 is in the flat state, the first support member 111 and the second support member 111' can provide better support for the screen 30; when the folding device 100 is in the folded state , the cross section of the folding device 100 presents a drop-shaped receiving space. When the folding device 100 is applied to the folding case 10 and the electronic device 1, it is beneficial to reduce the folding of the folding case 10 and the electronic device 1. The gap improves the appearance and expressiveness, and increases the bending control of the screen 30 in the electronic device 1, which is beneficial to reducing the creases of the screen 30.

In the first rotating mechanism 130 , one end of the second rotating member 132 is rotatably connected to the main body 120 , and the other end is rotatably connected to the connecting member 134 . One end of the third rotating member 133 is rotatably connected to the main body 120 , and the other end is slidably connected to the connecting member 134 .

One end of the third rotating member 133 is rotatably connected to the main body 120 , and the other end is slidably connected to the connecting member 134 . The connecting member 134 is rotationally connected to the second supporting member 111'. The connecting member 134 rotates relative to the main body 120 to drive the first rotating member 131, the second rotating member 132 and the third rotating member 132. The rotating member 133 rotates.

In this embodiment, one end of the first rotating member 131 is rotatably connected to the main body 120 , and the other end is slidingly connected to the first supporting member 111 , wherein the one end of the first rotating member 131 is connected to the main body 120 . The other end of the first rotating member 131 is arranged opposite to each other. One end of the second rotating member 132 is rotatably connected to the main body 120 , and the other end is rotatably connected to the connecting member 134 . The one end of the second rotating member 132 is connected to the end of the second rotating member 132 . The other ends are arranged opposite to each other. One end of the third rotating member 133 is rotatably connected to the main body 120 , and the other end is slidingly connected to the connecting member 134 , wherein the one end of the third rotating member 133 and the end of the third rotating member 133 The other ends are arranged opposite to each other.

When the folding device 100 is folded, the first rotating member 131 of the first rotating mechanism 130 slides relative to the first supporting member 111 , and the first rotating member 131 of the second rotating mechanism 130 ′ slides relative to the second supporting member 111 'Sliding, the first rotating member 131, the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130 and the second rotating mechanism 130' rotate, and the third rotating member 133 is compared with the connecting member 134 Sliding, the first support member 111 and the second support member 111' fold each other; when the folding device 100 is unfolded, the first rotating member 131 of the first rotating mechanism 130 slides relative to the first supporting member 111, and the second rotating member The first rotating member 131 of the mechanism 130' slides relative to the second supporting member 111'. The first rotating member 131, the second rotating member 132 and the second rotating member 130 of the first rotating mechanism 130 and the second rotating mechanism 130' The three rotating members 133 rotate, the third rotating member 133 slides relative to the connecting member 134, and the first supporting member 111 and the second supporting member 111' unfold each other.

It should be noted that the so-called rotation means that the two moving parts can perform circular motion around the rotation axis. When two moving parts rotate, they can move part or all of the circumference around the axis of rotation. For example, if one end of the first rotating member 131 of the first rotating mechanism 130 is rotationally connected to the first supporting member 111, then the first rotating member 131 of the first rotating mechanism 130 and the first supporting member 111 can rotate. Circular motion around the axis of rotation. The so-called sliding refers to the parallel movement of two moving parts. There is only a displacement change between the two moving parts, but no angle change. For example, in this embodiment, the other end of the first rotating member 131 is slidingly connected to the main body 120, which means that there is a displacement change between the other end of the first rotating member 131 and the main body 120. , without any change in angle. Please refer to the instructions here for the subsequent rotation or sliding of each component, which will not be described again. The so-called rolling refers to both displacement changes and angle changes between two moving parts.

As can be seen from the above description, the first support member 111 and the second support member 111' can be folded or unfolded with each other. Therefore, the folding device 100 has a folded state and a flattened state, and can be switched from the flattened state to Folded state, and switching from folded state to flattened state. It can be understood that the folding device 100 also has a hovering state (also called an intermediate state) between the folding state and the flattening state. When the folding device 100 is in the folded state, the first supporting member 111 and the second supporting member 111' are located on the same side of the main body 120, and the first supporting member 111 and the second supporting member 111' are located on the same side of the main body 120. The support 111' cannot be folded any further. When the folding device 100 is in a flat state, the first supporting member 111 and the second supporting member 111' are located on opposite sides of the main body 120, and the first supporting member 111 and the second supporting member 111' are located on opposite sides of the main body 120. The second support member 111' is in a flat or nearly flat state. When the first support member 111 and the second support member 111' are in a flat state, the surfaces of the first support member 111 and the second support member 111' adjacent to the screen 30 are coplanar. When the first support member 111 and the second support member 111' are in an approximately flat state, the surfaces of the first support member 111 and the second support member 111' adjacent to the screen 30 are approximately coplanar. The state of the folding device 100 is related to the state of the electronic device 1 . When the first support member 111 and the second support member 111' in the folding device 100 are bent to each other, the screen 30 will be bent relative to each other; when the third support member in the folding device 100 is bent When a support member 111 and the second support member 111' are flattened to each other, the screen 30 will be flattened to each other. Therefore, when the folding device 100 is in a folded state, the electronic device 1 is also in a folded state; when the folding device 100 is in a flattened state, the electronic device 1 is also in a flattened state.

The member 131 slides relative to the first supporting member 111 , and the third rotating member 133 slides relative to the connecting member 134 , so that the two first supporting members 111 fold with each other. When each connecting piece 134 in the first rotating mechanism 130 and the second rotating mechanism 130' moves away from each other, the two second rotating pieces 132 rotate away from each other compared to the main body 120 and the connecting piece 134. , the two first rotating members 131 rotate relative to the main body 120 and move away from each other, the two third rotating members 133 rotate relative to the main body 120 and move away from each other, the third rotating member of the first rotating mechanism 130 A rotating member 131 slides relative to the first supporting member 111, the first rotating member 131 of the second rotating mechanism 130' slides relative to the second supporting member 111', and the third rotating member 133 slides relative to the second supporting member 111'. Slide relative to the connecting member 134 so that the first supporting member 111 and the second supporting member 111' unfold toward each other. In other embodiments, the first support member 111 and the second support member 111' may be brought closer to each other to drive the various components of the first rotation mechanism 130 and the second rotation mechanism 130' to move. . The embodiment of the present application allows the first support member 111 and the second support member 111' to move relative to each other.

In the first rotating member 131, the second rotating member 132 and the third rotating member 133 of the first rotating mechanism 130. Correspondingly, the decorative part 1400 can also be used to block the gap between the assembly formed by the second supporting part 111' and the connecting part 134 and the main body 120, thereby reducing or preventing dust, water vapor, etc. from entering.

The movement process of the folding device 100 in several embodiments is described below. It can be understood that the movement process of the folding device 100 introduced in the following embodiments should not be understood as limiting the movement process of the folding device 100 introduced in the embodiments of the present application. This application does not limit the active and passive relationships of each component, as well as the movement timing.

First, the movement process of the folding device 100 from the flattened state to the folded state will be introduced. In one embodiment, when the folding device 100 is folded from the flat state, one of the connecting parts 134 (the connecting part 134 of the first rotating mechanism 130 and the connecting part 134 of the second rotating mechanism 130' is One) is bent relative to the main body 120 toward the other connecting piece 134 (the other one of the connecting piece 134 of the first rotating mechanism 130 and the connecting piece 134 of the second rotating mechanism 130') so that the two connecting pieces 134 closer. In another embodiment, when the folding device 100 is bent from a flat state, both connecting members 134 are bent so that the two connecting members 134 are brought closer together. When the two connecting members 134 come closer, the two second rotating members 132 rotate relative to the main body 120 and the connecting member 134 and move closer to each other, and the two first rotating members 131 rotate relative to the main body 120 The two third rotating members 133 rotate relative to the main body 120 and move closer to each other. The first rotating member 131 of the first rotating mechanism 130 slides relative to the first supporting member 111, so The first rotating member 131 of the second rotating mechanism 130' slides relative to the second supporting member 111', and the third rotating member 133 slides relative to the connecting member 134, so that the first supporting member 111 and the second support member 111' are folded with each other. In addition, the connecting member 134 of the first rotating mechanism 130 is rotationally connected to the first supporting member 111. Therefore, the end of the first supporting member 111 away from the main body 120 can be closer to the connecting member 134. Another first supporting member 111; the connecting member 134 of the second rotating mechanism 130' is rotationally connected to the second supporting member 111'. Therefore, the end of the second supporting member 111' away from the main body 120 can be compared The connecting member 134 of the second rotating mechanism 130' is further close to the second supporting member 111' until the folding device 100 is in a folded state. When the folding device 100 is in a folded state, the first supporting member 111 and the second supporting member 111 are in a folded state. The support member 111' and the main body 120 form a water drop-shaped cross section.

The movement process of the folding device 100 from the folded state to the unfolded state will be introduced below. In one embodiment, when the folding device 100 is unfolded from a fully folded state, one of the connecting members 134 is moved away from the other connecting member 134 to unfold the folding device 100 . In another embodiment, when the folding device 100 is unfolded from the folded state, both connecting members 134 are unfolded in a direction away from the other connecting member 134 . When the two connecting members 134 move away from each other, the two second rotating members 132 rotate away from each other relative to the main body 120 and the connecting member 134 , and the two first rotating members 131 rotate relative to the main body 120 and the connecting member 134 . The main body 120 rotates away from each other, the two third rotating members 133 move away from each other relative to the active rotation, and the first rotating member 131 of the first rotating mechanism 130 slides relative to the first supporting member 111, The first rotating member 131 of the second rotating mechanism 130' slides relative to the second supporting member 111', and the third rotating member 133 slides relative to the connecting member 134, so that the first supporting member 111 and the second support member 111' spread out from each other. In addition, the connecting piece 134 of the first rotating mechanism 130 is rotationally connected to the first supporting member 111, and the connecting piece 134 of the second rotating mechanism 130' is rotationally connected to the second supporting member 111'. Therefore, the first supporting member The end of the member 111 away from the main body 120 can be closer to the second support member 111' than the connecting member 134 until the folding device 100 is in a flat state.

This application also provides a folding case 10, which includes the folding device 100 described in any of the previous embodiments and two cases 500. Please refer to the previous description of the folding device 100 and will not repeat it here. The folding device 100 is located between the two housings 500. The two housings 500 are respectively connected to the connecting piece 134 of the first rotating mechanism 130 and the connection of the second rotating mechanism 130' of the folding device 100. Item 134.

The folding device 100 is disposed between the two housings 500, and the two connecting members 134 are respectively received in the receiving grooves 111a of the two housings 500, and the two connecting members 134 are fixedly connected to the two housings respectively. 500.

Optionally, please refer to FIG. 3 , the second supporting surface 500a of the housing 500 (that is, the surface of the housing 500 facing away from the decorative component 1400 when the folding housing 10 is in the flat state), the first supporting surface The first supporting surface 111f of the member 111 (that is, the surface of the first supporting member 111 facing away from the connecting member 134) and the first end surface 123 of the main body 120 are coplanar.

When the second supporting surface 500a of the housing 500, the first supporting surface 111f of the first supporting member 111, and the first end surface 123 of the main body 120 are coplanar, the second supporting surface of the housing 500 500a, there is no step difference between the first supporting surface 111f of the first supporting member 111 and the first end surface 123 of the main body 120. When the folding case 10 is used to support the screen 30, the folding device 100 is completely in the In the flat state, the screen 30 will not be affected by the step difference, and the screen 30 will not have bad problems such as colored dots and bright spots, ensuring the reliability of the screen 30. At the same time, it also improves the touch feel of the screen 30 and improves the user experience. .

Please refer to FIG. 38 , which is a schematic diagram of the first rotation axis and the second rotation axis in the folding mechanism shown in FIG. 4 . The first rotation axis L1 of the first rotating member 131 relative to the main body 120 is parallel to the second rotation axis L2 of the third rotating member 133 relative to the main body 120 .

Wherein, the first rotation axis L1 is parallel to the second rotation axis L2, which means that the extension direction of the first rotation axis L1 is the same as the extension direction of the second rotation axis L2, and the second rotation axis L2 There is a certain distance between a rotation axis L1 and the second rotation axis L2. In other words, the first rotation axis L1 and the second rotation axis L2 are parallel to each other and do not overlap. In this embodiment, the first rotation axis L1 and the second rotation axis L2 are parallel and offset. The specific situation will be described in detail later.

The first rotation axis L1 and the second rotation axis L2 are both parallel to the central axis of the folding device 100 . The central axis of the folding device 100 may refer to line M in the drawings. The first rotation axis L1 and the second rotation axis L2 are parallel to facilitate the first rotation member 131 and the third rotation member 133 to rotate in the same direction. In this embodiment, the direction of the central axis M of the folding device 100 can be understood as the width direction of the electronic device 1 .

The first rotation axis L1 is parallel to the second rotation axis L2, which allows the first rotation member 131 and the third rotation member 133 to rotate in the same direction, thereby reducing the size of the first rotation mechanism 130, The matching gap between the main body 120, the first support member 111 and the connecting member 134 reduces the rotational position and shaking of the folding device 100, thereby improving the first support member 111 and the connecting member 134. The accuracy of the first rotating member 131 rotating relative to the main body 120 and the synchronous rotation of the connecting member 134 and the third rotating member 133 relative to the main body 120 makes the folding device 100 When applied to the folding case 10, the movement control of the case 500 carried by the folding device 100 is more precise.

Please continue to refer to Figure 38. The first rotating member 131 and the third rotating member 133 are arranged along the first direction D1, and the first rotating axis L1 and the second rotating axis L2 are staggered along the second direction D2. ; and/or, the first rotation axis L1 and the second rotation axis L2 are offset along the third direction D3, wherein the first direction D1, the second direction D2 and the third direction D3 perpendicular to each other.

In this embodiment, in the same rotating mechanism: the first rotating member 131 and the third rotating member 133 are arranged along the direction of the central axis M of the folding device 100 . The first rotation axis L1 and the second rotation axis L2 are offset along the second direction D2, and/or the first rotation axis L1 and the second rotation axis L2 are offset along the third direction D3. . That is, the first rotation axis L1 and the second rotation axis L2 are offset along at least one of the second direction D2 and the third direction D3. The second direction D2 may be the length direction of the electronic device 1 , and the third direction D3 may be the thickness direction of the electronic device 1 .

In this embodiment, the first rotation axis L1 and the second rotation axis L2 are offset along the second direction D2 and the third direction D3 as an example for illustration. In other embodiments, the first rotation axis L1 and the second rotation axis L2 are offset along one of the second direction D2 and the third direction D3.

The first rotation axis L1 and the second rotation axis L2 are parallel and offset, that is, in this embodiment, the first rotation axis L1 and the second rotation axis L2 are aligned in the second direction D2 and At least one of the third directions D3 is misaligned, so that when the folding device 100 is in a stationary state (that is, when the folding device 100 is not rotating), the first support member 111 is restricted from being able to move relative to the first supporting member 111 . The rotating member 131 moves, and the connecting member 134 is restricted from moving relative to the third rotating member 133 . In other words, the first support member 111 is stationary relative to the first rotating member 131 , and the connecting member 134 is stationary relative to the third rotating member 133 , thereby improving the structure of the folding device 100 stability. It should be noted that when the folding device 100 is in motion, the rotation of the connecting member 134 can still directly or indirectly drive the first rotating member 131 and the third rotating member 133 to rotate.

In addition, when the first rotation axis L1 and the second rotation axis L2 are both parallel to the central axis M of the folding device 100, the first rotation member 131 rotates around the first rotation axis L1 and the third rotation member 133 rotates around the second rotation axis L2. , one side of the folding device 100 can be flattened and folded. When the first rotation axis L1 and the second rotation axis L2 are arranged along the direction of the central axis M of the folding device 100, and when the first rotation axis L1 and the second rotation axis L2 are misaligned along the second direction D2, the first rotation axis L1 and the second rotation axis L2 can be disposed in the second direction D2. Constraints are formed in the second direction D2 to reduce the fit gap of the folding device 100 in the second direction D2; when the first rotation axis L1 and the second rotation axis L2 are misaligned along the third direction D3, a constraint can be formed in the third direction D3. constraint, reducing the fitting gap of the folding device 100 in the third direction D3. When the folding device 100 switches between the flattened state and the folded state, the shaking of the first rotating member 131 and the third rotating member 133 can be reduced, and better The movement of the first rotating member 131 and the third rotating member 133 is controlled.

When the connecting member 134 moves from the first position to the second position relative to the main body 120: the first rotating member 131 rotates relative to the main body 120 and rotates relative to the first support. The member 111 slides a first distance; the second rotating member 132 rotates relative to the main body 120 and slides a second distance relative to the connecting member 134, and the second distance is not equal to the first distance, where , the first position corresponds to the folding device 100 being in a flattened state, and the second position corresponds to the folding device 100 being in a folded state.

It can be understood that the first position, that is, the first rotating member 131 , the third rotating member 133 , the first supporting member 111 and the connecting member 134 are all in a flat state relative to the main body 120 position; the second position, that is, the first rotating member 131, the third rotating member 133, the first supporting member 111 and the connecting member 134 are all in a folded position relative to the main body 120. Location.

The main body 120 has an end surface (ie, the first end surface 123 ) adjacent to the first support member 111 when the folding device 100 is in a folded state. The end surface is the surface facing the screen 30 when the folding device 100 is applied to the electronic device 1 . In this embodiment, when the folding device 100 is in a flattened state, the first rotation axis L1 is closer to the end surface than the second rotation axis L2. During the movement of the first supporting member 111 from the first position to the second position relative to the main body 120 , the first rotating member 131 slides a first distance relative to the first supporting member 111 . During the movement of the connecting member 134 from the first position to the second position relative to the main body 120, the second rotating member 132 slides a second distance relative to the connecting member 134. The first distance is smaller than the second distance.

In other embodiments, when the folding device 100 is in the flattened state, the first rotation axis L1 is further away from the end surface than the second rotation axis L2. During the movement of the first supporting member 111 from the first position to the second position relative to the main body 120 , the first rotating member 131 slides a first distance relative to the first supporting member 111 . When the connecting member 134 moves from the first position to the second position relative to the main body 120 , the second rotating member 132 slides a second distance relative to the connecting member 134 . The first distance is greater than the second distance.

One end of the first rotating member 131 is rotatably connected to the main body 120 , the other end of the first rotating member 131 is slidingly connected to the first support member 111 , and one end of the third rotating member 133 is rotatably connected to the main body 120 , the other end of the third rotating member 133 is slidingly connected to the connecting member 134, and when the connecting member 134 moves from the first position to the second position relative to the main body 120, the first rotating member The third rotating member 133 slides relative to the first supporting member 111 and slides relative to the leveling member. Therefore, the rotation axis of the connecting member 134 and the first supporting member 111 can be designed. (Different from the first rotation axis L1 and the second rotation axis L2), in order to realize that the movement trajectory of the connecting member 134 relative to the main body 120 from the first position to the second position is an arc or approximately It is an arc, which can reduce the pulling force of the connecting member 134 on the screen 30 during movement.

Please refer to FIG. 39 , which is a schematic diagram of the second rotation axis and the third rotation axis in the folding mechanism shown in FIG. 4 . The second rotation axis L2 of the third rotating member 133 relative to the main body 120 is parallel to the third rotation axis L3 of the second rotating member 132 relative to the main body 120 .

Wherein, the second rotation axis L2 is parallel to the third rotation axis L3, which means that the extension direction of the second rotation axis L2 is the same as the extension direction of the third rotation axis L3, and the third rotation axis L3 There is a certain distance between the second rotation axis L2 and the third rotation axis L3. In other words, the second rotation axis L2 and the third rotation axis L3 are parallel to each other and do not overlap. In this embodiment, the second rotation axis L2 and the third rotation axis L3 are parallel and offset. The specific situation will be introduced in detail later.

The second rotation axis L2 and the third rotation axis L3 are both parallel to the central axis of the folding device 100 . The second rotation axis L2 and the third rotation axis L3 are parallel to facilitate the rotation of the first rotating member 131 and the second rotating member 132 in the same direction.

The second rotation axis L2 is parallel to the third rotation axis L3, which can cause the first rotation member 131 and the second rotation member 132 to rotate in the same direction, thereby reducing the size of the first rotation mechanism 130 and the The cooperation between the main body 120, the first support member 111 and the connecting member 134 is reduced, and the rotational position and shaking of the folding device 100 are reduced, thereby lifting the connecting member 134 and the third connecting member 134. The precision of the three rotating members 133 when rotating relative to the main body 120 and when the connecting member 134 and the second rotating member 132 rotate synchronously relative to the main body 120 makes the folding device 100 suitable for all applications. When folding the housing 10, the movement control of the housing 500 carried by the folding device 100 is more precise.

The second rotating member 132 and the third rotating member 133 are arranged along the first direction D1, and the second rotating axis and the third rotating axis are in at least one of the second direction D2 and the third direction D3. The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

In this embodiment, the second rotating member 132 and the third rotating member 133 are arranged along the direction of the central axis of the folding mechanism. The second rotation axis L2 and the third rotation axis L3 are offset along the second direction D2, and/or the second rotation axis L2 and the third rotation axis L3 are arranged along the second direction D2. At least one of the two directions D2 and the third direction D3 is disposed in an offset manner. The second direction D2 may be the length direction of the electronic device 1 , and the third direction D3 may be the thickness direction of the electronic device 1 .

In this embodiment, the second rotation axis L2 and the third rotation axis L3 are offset along the second direction D2 and the third direction D3 as an example for illustration. In other embodiments, the second rotation axis L2 and the third rotation axis L3 are offset along one of the second direction D2 and the third direction D3.

The second rotation axis L2 and the third rotation axis L3 are parallel and offset, that is, in this embodiment, the second rotation axis L2 and the third rotation axis L3 are in the second direction D2 and at least one of the third directions D3 is misaligned, so that when the folding device 100 is in a stationary state (that is, when the folding device 100 is not rotating), the connecting member 134 is restricted from rotating relative to the second direction. The member 132 and the third rotating member 133 move. In other words, the connecting member 134 is stationary relative to the second rotating member 132 , and the connecting member 134 is stationary relative to the third rotating member 133 , thereby improving the structural stability of the folding device 100 . It should be noted that when the folding device 100 is in motion, the rotation of the connecting member 134 still drives the second rotating member 132 and the third rotating member 133 to rotate.

In addition, when the second rotation axis L2 and the third rotation axis L3 are both parallel to the central axis of the folding device 100, the third rotation member 133 rotates around the second rotation axis L2. The member 132 rotates around the third rotation axis L3, so that one side of the folding device 100 can be flattened or folded. When the second rotation axis L2 and the third rotation axis L3 are arranged along the central axis of the folding device 100 , and the second rotation axis L2 and the third rotation axis L3 are along the second direction D2 When the misalignment is set, constraints can be formed in the second direction D2 to reduce the fitting gap of the folding device 100 in the second direction D2; when the second rotation axis L2 and the third rotation axis L3 move along the third direction D3 When dislocated, constraints can be formed in the third direction D3 to reduce the fitting gap of the folding device 100 in the third direction D3, so that when the folding device 100 switches between the flattened and folded states, the gap can be reduced. The rocking of the second rotating member 132 and the third rotating member 133 can better control the movement of the second rotating member 132 and the third rotating member 133 .

It should be noted that in the above embodiment, the first rotating mechanism 130 and the second rotating mechanism 130' are symmetrical with respect to the main body 120 for illustration. In other embodiments, the first rotating mechanism 130 and the second rotating mechanism 130' may also be asymmetrical with respect to the main body 120. In one embodiment, the first rotating mechanism 130 and the second rotating mechanism 130 are not aligned in a direction perpendicular to the central axis M of the main body 120 , but are arranged in a misaligned manner. In another embodiment, the relative positional relationship between the first rotating member 131 , the second rotating member 132 and the third rotating member 133 in the first rotating mechanism 130 is different from that of the second rotating mechanism. The relative position of 130' is different. For example, in the first rotating mechanism 130, the second rotating member 132, the first rotating member 131 and the third rotating member 133 are arranged in sequence; in the second rotating mechanism 130', the third rotating member 133 can be arranged in sequence. , the second rotating member 132 and the first rotating member 131 are arranged in order; or, in the second rotating mechanism 130', the first rotating member 131, the second rotating member 132 and the third rotating member 133 are arranged in order. .

Please refer to the previous description of the folding device 100 and will not repeat it here. The folding device 100 is located between the two housings 500. The two housings 500 are respectively connected to the connecting piece 134 of the first rotating mechanism 130 and the second rotating mechanism 130' of the folding device 100. When the connecting piece 134 of the first rotating mechanism 130 rotates and the connecting piece 134 of the second rotating mechanism 130' rotates, the two housings 500 rotate to between the unfolded state and the folded state. switch.
