[0022] like Figure 1-2As shown, this embodiment provides a folding device, which includes a main body 110, a moving assembly 120, a first rotating assembly 130 and a second rotating assembly 140. The main body 110 has a moving space 170; the moving assembly 120 is installed on the main body 110 and is arranged in the moving space 170; the first rotating assembly 130 is installed on the main body 110, and the first rotating assembly 130 is located on one side of the moving assembly 120; the second rotating assembly 140 is installed on the main body 110, and the second rotating assembly 140 is located on the other side of the moving assembly 120; when at least one of the first rotating assembly 130 and the second rotating assembly 140 rotates around the moving assembly 120, the moving assembly 120 moves in the moving space 170; when the moving assembly 120 moves in the moving space 170, it drives the first rotating assembly 130 and the second rotating assembly 140 to move closer to or farther from each other around the moving assembly 120. That is, when the first rotating component 130 and / or the second rotating component 140 rotate, they can drive the moving component 120 to move along the moving space 170. At the same time, when the moving component 120 moves along the moving space 170, the moving component 120 can also drive the first rotating component 130 and the second rotating component 140 to move closer to or farther away from each other; ensuring that no matter whether the first rotating component 130 or the second rotating component 140 is rotated alone, the first rotating component 130 and the second rotating component 140 can move closer to or farther away from each other at the same time.
[0023] In this embodiment, if Figure 2 and Figure 8 As shown, the first rotating assembly 130 includes a first rotating arm 131 and a first screw 132 installed on the first rotating arm 131. The first rotating arm 131 is installed on the main body 110, and the first screw 132 is installed on the moving assembly 120. The second rotating assembly 140 includes a second rotating arm 141 and a second screw 142 installed on the second rotating arm 141. The second rotating arm 141 is installed on the main body 110, and the second screw 142 is installed on the moving assembly 120. The moving assembly 120 includes a slider 121; the slider 121 is installed in the moving space, and the slider 121 moves along the moving space. When the first rotating arm 131 rotates around the first screw 132 and / or the second rotating arm 141 rotates around the second screw 142, the first rotating arm 131 drives the moving assembly 120 to move via the first screw 132 and / or the second rotating arm 141 drives the moving assembly 120 to move via the second screw 142. That is to say, the two screws are fixed on the two rotating arms respectively, and the slider 121 is provided with two internal threads, and the two screws are installed in one internal thread respectively; when the two rotating arms approach or move away from each other, the slider 121 can move to one side, thereby ensuring that the two rotating arms approach or move away from each other at the same time.
[0024] In this embodiment, the first screw rod 132 and the second screw rod 142 are respectively cut off along the axis and half of them are removed; the movable component 120 is also half of the nut; this makes it easier to install the first screw rod 132 and the second screw rod 142 and the movable component 120. At the same time, since the first screw rod 132, the second screw rod 142 and the movable component 120 are all half, the installation space is also saved.
[0025] In this embodiment, the folding device further includes a first rod 153, a second rod 154, a first grinding arm 155, and a second grinding arm 156. The first rod 153 is mounted on the first rotating arm 131, and the second rod 154 is mounted on the second rotating arm 141; one side of the first grinding arm 155 is mounted on the moving assembly 120, and the other side of the first grinding arm 155 is mounted on the first rod 153; one side of the second grinding arm 156 is mounted on the moving assembly 120, and the other side of the second grinding arm 156 is mounted on the second rod 154; when the first rotating arm 131 rotates around the first screw rod 132 and / or the second rotating arm 141 rotates around the second screw rod 142, the first grinding arm 155 moves relative to the first rod 153 and / or the second grinding arm 156 moves relative to the second rod 154, and there is resistance when the first grinding arm 155 moves relative to the first rod 153 and / or the second grinding arm 156 moves relative to the second rod 154. By adopting the resistance of the first grinding arm 155 to move relative to the first rod 153 and the resistance of the second grinding arm 156 to move relative to the second rod 154, the first rotating arm 131 and the second rotating arm 141 can prevent the first rotating arm 131 and the second rotating arm 141 from rotating when they are not subjected to rotational force. In the first embodiment, if Figure 2 and Figure 5As shown, in this embodiment, the folding device further includes a first electric control component 150 and a second electric control component 160. The first electric control component 150 includes a first stepper motor 151, and the second electric control component 160 includes a second stepper motor 152. The first electric control component 150 is installed on the first rotating component 130; the second electric control component 160 is installed on the second rotating component 140; the first grinding arm 155 is connected to the first rod 153 via threads, and the second grinding arm 156 is connected to the second rod 154 via threads; the first stepper motor 151 can drive the first rod 153 to rotate and drive the first grinding arm 155 to move via threads; the second stepper motor 152 can drive the second rod 154 to rotate and drive the second grinding arm 156 to move via threads; when the first stepper motor 151 and the second stepper motor 152 work synchronously, the first stepper motor 151 and the second stepper motor 152 move the corresponding first grinding arm 155 and the second grinding arm 156 via threads, and the first grinding arm 155 and the second grinding arm 156 drive the moving component 120 to move, and the moving component 120 drives the first screw 132 to drive the first rotating arm 131 and the second screw 142 to drive the second rotating arm 141 to rotate around the moving component 120. The use of dual motors to simultaneously control the movement of the grinding arm through threads and then control the movement of the moving assembly 120 to rotate the first rotating arm 131 and the second rotating arm 141 can effectively ensure the angular accuracy of the rotation of the first rotating arm 131 and the second rotating arm 141. At the same time, the use of threads further ensures the rotation stability of the first rotating arm 131 and the second rotating arm 141.
[0026] In the second embodiment, if Figure 2-3 As shown, in this embodiment, the first rod 153 and the second rod 154 are round rods. The first grinding arm 155 is mounted on the first rod 153, and there is friction between the first grinding arm 155 and the first rod 153; the second grinding arm 156 is mounted on the second rod 154, and there is friction between the second grinding arm 156 and the second rod 154. When the first rotating arm 131 rotates around the first screw rod 132 and / or the second rotating arm 141 rotates around the second screw rod 142, the first screw rod 132 and / or the second screw rod 142 drive the moving assembly 120 to move, and the moving assembly 120 drives the first grinding arm 155 and the second grinding arm 156 to overcome the friction and move along the round rod. The friction force between the first grinding arm 155 and the first rod 153, and the friction force between the second grinding arm 156 and the second rod 154, ensure that when the first rotating arm 131 and the second rotating arm 141 drive the moving component 120 to move, the moving component 120 drives the first grinding arm 155 and the second grinding arm 156 to move with resistance, thereby ensuring that the first rotating arm 131 and the second rotating arm 141 will not rotate quickly to drive the moving component 120 to move, ensuring the stability of the angle between the first rotating arm 131 and the second rotating arm 141, and preventing the first rotating arm 131 and the second rotating arm 141 from swinging easily.
[0027] In the third embodiment, if Figure 2 and Figure 6As shown, in this embodiment, the folding device further includes a first nut 161 and a second nut 162. The first rod 153 and the second rod 154 are both provided with threads; the first nut 161 is mounted on the first rod 153, and the second nut 162 is mounted on the second rod 154; the first grinding arm 155 is sleeved on the first nut 161, and the first grinding arm 155 and the first nut 161 have friction; the second grinding arm 156 is sleeved on the second nut 162, and the second grinding arm 156 and the second nut 162 have friction. When the first stepper motor 151 drives the first nut 161 to move via the first rod 153 and / or the second stepper motor 152 drives the second nut 162 to move via the second rod 154, the first nut 161 drives the moving assembly 120 to move via the first grinding arm 155 under the action of friction and / or the second nut 162 drives the moving assembly 120 to move via the second grinding arm 156 under the action of friction; the moving assembly 120 causes the first screw rod 132 to drive the first rotating arm 131 and the second screw rod 142 to drive the second rotating arm 141 to rotate around the moving assembly 120. When the first rotating arm 131 rotates around the first screw rod 132 and / or the second rotating arm 141 rotates around the second screw rod 142, the first screw rod 132 and / or the second screw rod 142 drive the moving assembly 120 to move, and the moving assembly 120 drives the first grinding arm 155 to overcome the friction and move along the first nut 161 and the second grinding arm 156 to overcome the friction and move along the second nut 162. That is to say, the static friction force of the first grinding arm 155 on the first screw nut 161 and the static friction force of the second grinding arm 156 on the second screw nut 162 are f; and when the first stepper motor 151 and / or the second stepper motor 152 are started, the first stepper motor 151 drives the first screw nut 161 to move through the first rod 153 and / or the second stepper motor 152 drives the second screw nut 162 to move through the second rod 154. The force applied is F1, and at this time, the force F1 is less than f; and when the first rotating arm 131 is pushed to rotate around the first screw rod 132 and / or the second rotating arm 1 When 41 rotates around the second screw rod 142, the moving assembly 120 drives the first grinding arm 155 to move along the first nut 161 and the second grinding arm 156 to move along the second nut 162. At this time, the thrust F2 is applied, and the force of F2 is greater than f; when two stepper motors are used to realize the rotation of the two rotating arms, the force of F1 is less than f, which can ensure that the two stepper motors can drive the two rotating arms to rotate; and when the two rotating arms rotate, the force of F2 is greater than f, which can ensure that the two rotating arms can be pushed; it can ensure that the rotating arms can be driven both electrically and manually. The use of electric and manual pushing methods to realize the rotation of the first rotating arm 131 and the second rotating arm 141 can still be considered to move the first rotating arm 131 and the second rotating arm 141 closer to or farther from each other when the stepper motor cannot be started due to a complete lack of power.
[0028] In this embodiment, the radii of the first screw 132 and the second screw 142 are both 3.20 mm; the helix angles of the first screw 132 and the second screw 142 are both 55-65 degrees, and the helix angles of the first screw 132 and the second screw 142 are the same, and the helix angle of 55-65 degrees makes the first screw 132 and the second screw 142 not self-locking with the moving component 120; the non-self-locking of the first screw 132 and the second screw 142 can ensure that when one of the rotating arms is rotated, the other rotating arm is driven to rotate at the same time through the moving component 120, ensuring that the two rotating arms can approach or move away from each other at the same time.
[0029] In the first and third embodiments, the helix angle of the threads provided on the first rod 153 and the second rod 154 is 3-5 degrees, and the helix angle of 3-5 degrees makes the first rod 153 and the second rod 154 self-locking. After the first rod 153 and the second rod 154 stop the rotation of the two rotating arms, the first rod 153 and the second rod 154 are self-locking to prevent the rotating arms from rotating.
[0030] like Figure 6As shown, in the third embodiment, the folding device further includes a position code 200 and a real-time variable pitch control device 210. The position code 200 is respectively arranged on the first nut 161, the second nut 162, the first grinding arm 155 and the second grinding arm 156; the position code 200 is provided with a scale, and the real-time variable pitch control device 210 is used to monitor the position of the position code 200 on the first nut 161 and the first grinding arm 155 and the second nut 162 and the second grinding arm 156, and controls the first stepper motor 151 and the second stepper motor 152 to adjust according to the position of the position code 200. That is to say, during installation, the first nut 161 is located at the initial position of the first grinding arm 155 and the second nut 162 is located at the initial position of the second grinding arm 156, which are set positions. When the first rotating arm 131 and the second rotating arm 141 are pushed to rotate and the two stepper motors are not started, the two rotating arms move along the corresponding nut through the moving assembly 120, and the positions of the two nuts and the corresponding grinding arms change relative to each other. If the stepper motor is directly started to rotate without adjustment at this time, the nut and the corresponding grinding arm may be separated. The real-time variable pitch control device 210 is used to monitor the position of the position code 200 in real time. When the first nut 161 is located at the initial position of the first grinding arm 155 and the second nut 162 is located at the initial position of the second grinding arm 156, the first nut 161 is located at the initial position of the first grinding arm 155 and the second nut 162 is located at the initial position of the second grinding arm 156. 2 is located at the initial position of the second grinding arm 156, that is, the position code 200 is offset, the real-time variable pitch control device 210 can detect the offset in time, and trigger the corresponding stepper motor to start, so that the first nut 161 is adjusted to the initial position of the first grinding arm 155 and the second nut 162 is adjusted to the initial position of the second grinding arm 156; it can effectively ensure that no matter whether the stepper motor is started and / or the two rotating arms are driven to rotate, the first nut 161 can be located at the initial position of the first grinding arm 155 and the second nut 162 can be located at the initial position of the second grinding arm 156, so as to prevent the first nut 161 from being separated from the first grinding arm 155 and the second nut 162 from being separated from the second grinding arm 156.
[0031] In this embodiment, the moving assembly 120 includes a slider 121 ; the slider 121 is installed in the moving space, and the slider 121 moves along the moving space.
[0032] like Figure 4-6As shown, in this embodiment, the folding device further includes a fixed block 220, a first rotary arm 240 and a second rotary arm 250. The fixed block 220 is fixedly mounted on the body 110; the first rotary arm 240 is mounted on the fixed block 220; the second rotary arm 250 is mounted on the fixed block 220; when the first rotating arm 131 rotates around the first screw rod 132 and / or the second rotating arm 141 rotates around the second screw rod 142, the first rotary arm 240 and the second rotary arm 250 rotate around the fixed block 220. The first rotary arm 240 and the second rotary arm 250 follow the first rotating arm 131 and the second rotating arm 141, so that when the moving assembly 120 moves, the movement is more stable under the action of the fixed block 220 being fixedly mounted on the body 110.
[0033] like Figure 7 As shown, in this embodiment, the folding device also includes a trigger mechanism 230, and the trigger mechanism 230 is triggered by facial recognition, fingerprint recognition, etc. The trigger mechanism 230 can control the start of the stepper motor, that is, when the initial angle between the first rotating arm 131 and the second rotating arm 141 is less than 180 degrees, the trigger mechanism 230 triggers the stepper motor to make the angle between the first rotating arm 131 and the second rotating arm 141 reach 180 degrees; when the initial angle between the first rotating arm 131 and the second rotating arm 141 is 180 degrees, the trigger mechanism 230 triggers the stepper motor to make the first rotating arm 131 and the second rotating arm 141 approach each other so that the angle between them is 0 degrees.
[0034] like Fig. 9 As shown, this embodiment provides a mobile phone 300, including a folding device 100, a first display module 310 and a second display module 320.
