In this embodiment, the display 1100 is a flexible display 1100. The first display portion 1110 and the second display portion 1120 are also bendable in nature when not secured.

Referring to fig. 3 and 4, fig. 4 is a schematic view of a split structure of a main body of the foldable electronic device shown in fig. 3.

In this embodiment, the main body 1200 includes a first housing 200, a second housing 300, a rotation mechanism 400, and a lock mechanism 100. The rotation mechanism 400 is installed between the first and second housings 200 and 300, and the rotation mechanism 400 is connected with the first and second housings 200 and 300, respectively, to achieve a rotational connection between the first and second housings 200 and 300, and the first and second housings 200 and 300 can be rotated relatively by the rotation mechanism 400, so that the body 1200 is switched between the folded and unfolded states.

The side of the first and second housings 200 and 300 facing away from the display 1100 is the inner surface of the mobile phone, and the side bearing the display 1100 is the outer side. Specifically, the display 1100 is mounted on the main body 1200, and the mounting surface is fixedly connected with the main body 1200. Specifically, the first housing 200 carries the first display portion 1110, and the second housing 300 carries the second display portion 1120. In other words, the first display portion 1110 is mounted to the first housing 200, and the second display portion 1120 is mounted to the second housing 300. Wherein the rotation mechanism 400 is disposed opposite to the third display portion 1130 to achieve bending of the display 1100.

Referring to fig. 1, when the mobile phone is in a folded state, the display 1100 is located at the outermost side and is in a visible state, so that the overall size of the mobile phone is reduced, and the mobile phone is convenient to carry.

The first housing 200, the second housing 300, and the rotation mechanism 400 are disposed in order along the X-axis direction, and the sum of the dimensions of the three is the dimension of the main body 1200 in the X-axis direction (including the assembly tolerance and the assembly gap between the three). The dimensions of the main body 1200 and the display 1100 in the X-axis direction are the same as those of the mobile phone in the X-axis direction, and the same includes an allowable tolerance range. The same dimensions of the first housing 200, the second housing 300, and the rotation mechanism 400 in the Y-axis direction may allow for assembly or production tolerances. The dimensions of the first housing 200, the second housing 300, and the rotation mechanism 400 along the Y-axis direction are the dimensions of the main body 1200 along the Y-axis direction, and the dimensions of the main body 1200 along the Y-axis direction are the same as the dimensions of the display 1100 and the mobile phone along the Y-axis direction. Of course, the same here can also allow for small deviations (assembly and production tolerances).

In the X-axis direction, the width of the first case 200 is greater than the width of the second case 300, and when the cellular phone is in a folded state, a portion of the first case 200 and the second case 300 are stacked in the Z-axis direction, another portion of the first case 200 is not folded with the second case 300, the thickness of the portion of the first case 200 not stacked with the second case 300 is greater than the thickness of the portion of the first case 200 stacked with the second case 300, and the thickness of the portion of the first case 200 not stacked with the second case 300 is the sum of the thicknesses of the stacked portions of the first case 200 and the second case 300.

In this embodiment, the rotation mechanism 400 is a hinge, and the rotation mechanism 400 is connected between the first housing 200 and the second housing 300, which corresponds to a rotation structure between the first housing 200 and the second housing 300, so as to enable the first housing 200 and the second housing 300 to rotate freely and fold relatively. Specifically, the rotation mechanism 400 includes two connected hinges, which are sequentially arranged along the Y-axis direction, wherein one hinge is connected to the first housing 200, and the other hinge is connected to the second housing 300; or the rotation mechanism 400 includes a hinge extending from one side of the handset to the other in the Y-axis direction. In other embodiments, the rotation mechanism 400 is two rotation shafts that are connected and rotatable relative to each other, wherein one rotation shaft is rotatably connected to the first housing 200, and the other rotation shaft is rotatably connected to the second housing 300, so as to implement the relative rotation of the first housing 200 and the second housing 300. In other embodiments, the rotation mechanism 400 may be a rotation mechanism of other structures, so long as the first housing 200 and the second housing 300 can rotate freely and fold relatively without damaging the display 1100.

The locking mechanism 100 is mounted on the first housing 200, and in the case where the main body 1200 is in a folded state, that is, in the case where the first housing 200 and the second housing 300 are stacked in the Z-axis direction, the locking mechanism 100 locks the first housing 200 and the second housing 300 to prevent the first housing 200 and the second housing 300 from being relatively unfolded. In the case where the main body 1200 needs to be switched to the unfolded state, the locking mechanism 100 may release the locking of the first and second housings 200 and 300 to relatively unfold the first and second housings 200 and 300.

In the Y-axis direction, the length dimension of the first portion 200A and the length dimension of the second portion 200B are both the same as the length dimension of the first housing 200. In the Z-axis direction, the height dimension of the first portion 200A is greater than the height dimension of the second portion 200B, and the height dimension of the first portion 200A is approximately twice the height dimension of the second portion 200B.

Referring to fig. 17 and 18, fig. 17 is a partial structural schematic view of the foldable electronic device shown in fig. 2. Fig. 18 is a schematic view of a partially cut-away structure of the foldable electronic device shown in fig. 1.

The lock mechanism 100 is disposed in the mounting groove 217 of the first housing 200. When in installation, the elastic piece 30 can be firstly placed in the second accommodating groove 227 from the assembly port 220, and specifically, the elastic piece 30 is positioned in the second accommodating groove 227; a part of the first sliding block 40 is located in the first receiving portion, a part of the second sliding block 50 is located in the second receiving portion, and another part of the first sliding block 40, the first elastic lever 60, the second elastic lever 61, the first connecting lever 70, the second connecting lever 71, the third elastic lever 62, the fourth elastic lever 63, and another part of the second sliding block 50 are located in the intermediate receiving portion. The two first abutment surfaces 41 of the first slider 40 abut against the two first abutment surfaces 221, respectively, and the two second abutment surfaces 51 of the second slider 50 abut against the two second abutment surfaces 222, respectively.

Then, the pressing member 10 is fitted into the first receiving groove 226 from the first fitting hole 218 such that the side of the pressing member 10 provided with the first connecting groove 16 is extended into the second receiving groove 227 while the first connecting rod 70 is extended into the first connecting groove 16, the first fitting hole 17 and the first connecting hole 72 are communicated and coaxial, and the second fitting hole 18 and the second connecting hole 73 are communicated and coaxial. Then, the first coupling shaft 81 is inserted into the first mounting hole 17 and the first coupling hole 72, and the second coupling shaft 82 is inserted into the second mounting hole 18 and the second coupling hole 73 to fix the first coupling rod 70 in the first coupling groove 16.

Next, the locking member 20 is inserted into the third receiving groove 228 from the second mounting port 219, and the side of the locking member 20 provided with the second connecting groove 27 is inserted into the second receiving groove 227, while the second connecting rod 71 is inserted into the second connecting groove 27, the third mounting hole 28 and the third connecting hole 74 are connected and coaxial, and the fourth mounting hole 29 and the fourth connecting hole 75 are connected and coaxial.

After the locking mechanism 100 is mounted, the operating surface 11A of the pressing member 10 extends out of the first receiving groove 226 from the first mounting opening 218, so as to be convenient for a user to operate. The second locking side 22 (guide convex arc surface) of the locking member 20 protrudes from the second mounting port 219 out of the third receiving groove 228 to enable the locking member 20 to lock the second housing 300. After the lock mechanism 100 is mounted, the first link 70 and the second link 71 are spaced apart in the X-axis direction, and the presser 10 and the lock member 20 are spaced apart in the X-axis direction. At this time, the first deforming member 30A and the second deforming member 30B are both in a natural state, that is, the first elastic lever 60 and the second elastic lever 61 are both inclined with respect to the Y axis, and the third elastic lever 62 and the fourth elastic lever 63 are both inclined with respect to the Y axis. The pressing member 10 and the locking member 20 maintain a first distance, and the first slider 40 and the second slider 50 maintain a first distance. Here, the first distance refers to a distance between the pressing side surface 11B of the pressing member 10 and the first locking side surface 21 of the locking member 20 in the X-axis direction in fig. 15. Here, the first pitch refers to a distance between the first connection surface 43 of the first slider 40 and the second connection surface 53 of the second slider 50 in the Y-axis direction in fig. 15.

In this embodiment, the second housing 300 is in a folded state relative to the first housing 200, and the portion of the locking member 20 extending out of the third receiving groove 228 extends into the locking groove 320 of the second housing 300 to lock the second housing 300, so that the second housing 300 is fixed relative to the first housing 200, and the first housing 200 and the second housing 300 maintain the folded state, preventing the first housing 200 and the second housing 300 from being accidentally opened, in other words, the locking mechanism 100 is in a locked state, and the second housing 300 is in a locked state. The cover 230 is fixed to the upper side of the mounting base 210 to close the mounting groove 217.

Referring also to fig. 16, the lock mechanism 100 is switched to the unlock state. When the locked state of the lock mechanism 100 needs to be released, that is, when the first housing 200 and the second housing 300 need to be released from the locked state, the second housing 300 is opened with respect to the first housing 200. A force directed toward the lock member 20 (i.e., the positive X-axis direction) is applied to the pressing member 10. Specifically, a force may be applied to the operation surface 11A in the direction toward the lock member 20, and at this time, the first slider 40 cannot move in the X-axis direction because the first slider 40 is restricted by the two first contact surfaces 221; the second slider 50 is restricted by the two second abutment surfaces 222, and the second slider 50 cannot move in the X-axis direction. The force applied to the operation surface 11A may be sequentially transmitted to the first connection rod 70, the first elastic rod 60, the first slider 40, the second elastic rod 61, and the force applied to the operation surface 11A may be sequentially transmitted to the first connection rod 70, the third elastic rod 62, the second slider 50, and the fourth elastic rod 63. At this time, the first elastic rod 60 and the second elastic rod 61 are elastically deformed, and the first elastic rod 60 and the second elastic rod 61 are deformed to be parallel to the Y axis, and the first sliding block 40 moves in the positive Y axis direction, that is, the first sliding block 40 gradually moves into the first accommodating portion until the first mating surface 42 of the first sliding block 40 abuts against the first limiting surface 223, and at this time, the first sliding block 40 stops moving.

The first elastic rod 60 and the second elastic rod 61 are elastically deformed, and the third elastic rod 62 and the fourth elastic rod 63 are elastically deformed while the first sliding block 40 moves in the Y-axis positive direction, and the third elastic rod 62 and the fourth elastic rod 63 are deformed to be parallel to the second reference surface. The second sliding block 50 moves in the Y-axis negative direction, that is, the second sliding block 50 gradually moves into the second accommodating portion until the second mating surface 52 of the second sliding block 50 abuts against the second limiting surface 224, and at this time, the second sliding block 50 stops moving. That is, at this time, the first slider 40 and the second slider 50 are away from each other in the second direction (Y-axis direction).

When the first elastic rod 60 and the second elastic rod 61 are deformed to be parallel to the Y axis and at the same time the third elastic rod 62 and the fourth elastic rod 63 are deformed to be parallel to the Y axis, the pressing member 10 and the locking member 20 approach each other in the X axis direction. That is, the pressing member 10 moves in the positive X-axis direction, and the locking member 20 moves in the negative X-axis direction, and at this time, the distance between the pressing member 10 and the locking member 20 is reduced from the first distance to the second distance, and the distance between the first slider 40 and the second slider 50 is increased from the first distance to the second distance. The first distance is referred to herein. The second distance means: here, the first distance refers to a distance between the pressing side 11B of the pressing member 10 and the first locking side 21 of the locking member 20 in fig. 16. Here, the second pitch refers to a distance between the first connection surface 43 of the first slider 40 and the second connection surface 53 of the second slider 50 in the Y-axis direction in fig. 16.

At this time, the locking member 20 is withdrawn from the locking groove 320 to release the locking of the first and second housings 200 and 300, and the second housing 300 can be opened with respect to the first housing 200. The force for opening the second housing 300 with respect to the first housing 200 may be from a manual operation by a user, such that the second housing 300 rotates with respect to the first housing 200 to open, or may be a component in the rotation mechanism 400 automatically rotates the second housing 300 with respect to the first housing 200 to open.

After the pressing force is released, the lock mechanism 100 is switched from the second state to the first state. Specifically, the first elastic lever 60 and the second elastic lever 61 restore the elasticity, the third elastic lever 62 and the fourth elastic lever 63 restore the elasticity, the first sliding block 40 moves in the Y-axis negative direction, that is, the first sliding block 40 gradually moves out of the first accommodating portion, and the second sliding block 50 moves in the Y-axis positive direction, that is, the second sliding block 50 gradually moves out of the second accommodating portion, and the first sliding block 40 and the second sliding block 50 approach each other. The first connecting rod 70 and the second connecting rod 71 are far away from each other along the X-axis direction, and the first connecting rod 70 and the second connecting rod 71 drive the pressing member 10 and the locking member 20 to be far away from each other, that is, the pressing member 10 moves toward the X-axis negative direction, and the locking member 20 moves toward the X-axis positive direction. At this time, the locking member 20 returns to the position where the second housing 300 can be locked again to be locked for the next time.

Referring to fig. 19 together, fig. 19 is a schematic structural diagram of a foldable electronic device according to an embodiment of the present application, which is switched from a second state to a first state.

When the second housing 300 is shifted from the opened state with respect to the first housing 200 to the folded state with respect to the first housing 200, the third surface 314 of the second housing 300 gradually approaches the first surface 243 of the first housing 200, the third side 310 of the second housing 300 gradually approaches the second mounting side 212 of the first housing 200, and the mating convex surface of the third side 310 of the second housing 300 pushes the guiding convex arc surface of the second locking side 22 of the locking member 20, so that the locking member 20 moves in a direction approaching the pressing member 10 (X-axis negative direction).

The pushing force of the second locking side 22 (the guiding convex arc surface) pushed by the mating convex surface of the third side 310 may be sequentially transferred to the second connecting rod 71, the second elastic rod 61, the first sliding block 40, and the first elastic rod 60, and the pushing force may be sequentially transferred to the second connecting rod 71, the fourth elastic rod 63, the second sliding block 50, and the third elastic rod 62. At this time, the first elastic rod 60 and the second elastic rod 61 are elastically deformed, and the first elastic rod 60 and the second elastic rod 61 are deformed to be parallel to the Y axis, and the first sliding block 40 moves in the positive direction of the Y axis, that is, the first sliding block 40 gradually moves into the first accommodating portion until the first sliding block 40 abuts against the first limiting surface 223; the third elastic rod 62 and the fourth elastic rod 63 are elastically deformed, and the third elastic rod 62 and the fourth elastic rod 63 are deformed to be parallel to the second reference surface, and the second sliding block 50 moves in the negative Y-axis direction, that is, the second sliding block 50 gradually moves into the second accommodating portion until the second sliding block 50 abuts against the second limiting surface 224.

When the first elastic rod 60 and the second elastic rod 61 are deformed to be parallel to the Y axis, and the third elastic rod 62 and the fourth elastic rod 63 are deformed to be parallel to the second reference plane, the pressing member 10 and the locking member 20 approach each other in the X axis direction. That is, the pressing member 10 moves in the positive X-axis direction, the locking member 20 moves in the negative X-axis direction, and the portion of the locking member 20 extending out of the third receiving groove 228 is retracted into the third receiving groove 228. After the third surface 314 of the second housing 300 moves to face the first surface 243 of the first housing 200, the mating arc surface 317 of the third side surface 310 of the second housing 300 moves to face the second mounting side 212 of the first housing 200, the locking groove 320 faces the guiding convex arc surface of the second locking side 22 of the locking member 20, and the pushing force of the third side surface 310 of the second housing 300 to the locking member 20 disappears. The first elastic rod 60 and the second elastic rod 61 restore the elasticity, the third elastic rod 62 and the fourth elastic rod 63 restore the elasticity, the first sliding block 40 moves in the Y-axis negative direction, that is, the first sliding block 40 gradually moves out of the first accommodating portion, and the second sliding block 50 moves in the Y-axis positive direction, that is, the second sliding block 50 gradually moves out of the second accommodating portion. The first connecting rod 70 and the second connecting rod 71 are far away from each other along the X-axis direction, and the first connecting rod 70 and the second connecting rod 71 drive the pressing member 10 and the locking member 20 to be far away from each other, that is, the pressing member 10 moves toward the X-axis negative direction, and the locking member 20 moves toward the X-axis positive direction. At this time, reinsertion of the locking piece 20 into the locking groove 320 locks the second housing 300.

In the present embodiment, by providing the elastic member 30 between the pressing member 10 and the locking member 20, the first, second, third and fourth elastic rods 60, 61, 62 and 63 of the elastic member 30 have elastic deformation ability, and the pressing member 10 and the locking member 20 are moved away from or toward each other by using the elastic deformation ability of the first, second, third and fourth elastic rods 60, 61, 62 and 63 to lock the locking member 20 to the first housing 200 or unlock the first housing 200. The first elastic bar 60, the second elastic bar 61, the third elastic bar 62 and the fourth elastic bar 63 of the elastic member 30 do not contact with the groove wall surface of the installation groove, and thus the first elastic bar 60, the second elastic bar 61, the third elastic bar 62 and the fourth elastic bar 63 of the elastic member 30 do not rub with the groove wall surface of the installation groove. Compared to the prior art scheme employing friction fit of the roller and the wedge surface, the friction force of the locking mechanism 100 is reduced and the pressing smoothness is increased.

In addition, the pressing member 10 protrudes from the side surface of the first housing 200 through the mounting groove 217, so that the thickness of the whole first housing 200 can be reduced compared with the case that the pressing member protrudes from the surface of the first housing 200 through the mounting groove 217, thereby facilitating the design of the mobile phone with reduced thickness.

The above is only a part of examples and embodiments of the present application, and the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are covered in the scope of the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
