Description

Technical Field

[0001] The present application relates to the technical field of mobile terminals, and in particular to a locking device, a folding terminal and a control method. Background Art

[0002] At present, as key technologies such as flexible screens and hinges gradually mature, the reliability of foldable screen mobile phones has been further improved. Users can get a larger screen and convenient carrying experience.

[0003] Existing external folding screen mobile phones are designed with buttons and locks. The buttons are connected to the locks. When the button is pressed, the lock tongue of the lock retracts into the main frame. After the press is canceled, the lock tongue pops out and recovers, which is used to lock the main and sub-frames of the mobile phone when the mobile phone is folded. In addition, like conventional mobile phones, external folding screen mobile phones are designed with buttons on the side for volume control. The buttons and volume buttons need to be designed separately on the casing, resulting in too much space on the casing, making manufacturing difficult, and also having a certain impact on the appearance consistency of the folding screen mobile phone. Summary of the invention

[0004] The present application provides a locking device, a folding terminal and a control method, which are used to solve the technical problem that the current buttons and locks can only lock the main and sub-frames of the folding mobile phone, and the buttons and locks have single functions.

[0005] The technical solution is as follows:

[0006] The first aspect of the present application provides a locking device, comprising: a locking body, including a force-applying structure and a locking tongue structure, the force-applying structure is connected to the locking tongue structure, and can move the locking tongue on the locking tongue structure in a retracting direction by applying force to the force-applying structure; a signal acquisition unit, used to collect action information of the locking body for operating the folding terminal.

[0007] The locking device can not only realize the locking between the main frame and the sub-frame of the folding terminal, but also, by operating the locking device, the interface of the folding mobile phone can be operated to increase the function of the locking device, provide a new way of human-machine interaction, and replace some buttons of the folding mobile phone (such as volume buttons), simplify the structure of the folding mobile phone shell, which is conducive to improving the consistency of the appearance of the folding screen mobile phone.

[0008] In some implementations, the signal collection unit includes a downward motion information collection unit, and the downward motion information collection unit is used to collect information when the lock body moves downward.

[0009] The information of the downward movement of the lock body is easy to collect, so it is preferred to set up a downward movement information collection unit.

[0010] In some implementations, the downward motion information collection unit is a pressure signal collection unit, and when the lock body moves downward, force can be applied to the pressure signal collection unit.

[0011] When the lock body moves downward, the pressure signal acquisition unit is triggered, so that the operation of entering the target application is facilitated by pressing the lock device.

[0012] In some implementations, the position of the force-applying structure on the lock tongue structure along the height direction is adjustable, a pressing surface is formed on the force-applying structure, and a pressed surface is formed on the lock tongue structure, which is located below the pressing surface and directly opposite to the pressing surface. When the force-applying structure moves to cause the downward action information collection unit to generate a signal, a gap exists between the pressing surface and the pressed surface.

[0013] Before the main frame and the sub-frame of the foldable terminal are locked together, the mobile phone can be operated first; of course, the force-applying structure can also be lightly pressed to trigger only the pressure signal acquisition unit to operate the mobile phone interface without locking the main frame and the sub-frame.

[0014] In some implementations, an elastic support structure is disposed below the force-applying structure, and the force-applying structure is supported on the elastic support structure.

[0015] By providing an elastic support structure, when the force-applying structure is pressed, the pressure signal acquisition unit is triggered first, and then the main frame and the sub-frame of the folding terminal are engaged.

[0016] In some implementations, the force-applying structure includes a top cap, a connecting shaft, and a limiting end. The connecting shaft passes through an assembly hole of the locking tongue structure. The length of the assembly hole is smaller than the length of the connecting shaft. A top cap and a limiting end are respectively provided at the top and bottom of the connecting shaft. The top cap and the limiting end limit the connecting shaft on the locking tongue structure.

[0017] The force-applying structure includes a top cap, a connecting shaft and a limiting end. The force-applying structure has a simple structure and is easy to process and manufacture.

[0018] In some implementations, the top cap includes a cap body and a pressing body, the pressing body is connected to the bottom of the cap body, the cross-sectional area of ​​the pressing body is larger than the cross-sectional area of ​​the assembly hole and smaller than the cross-sectional area of ​​the cap body, and the bottom surface of the pressing body forms a pressing surface.

[0019] By setting the cross-sectional area of ​​the pressing body to be larger than the cross-sectional area of ​​the assembly hole, the contact area between the user's finger and the force-applying structure is increased, making it easier for the user to press the force-applying structure.

[0020] In some implementations, the downward motion information collection unit is located below the force-applying structure, the elastic support structure is connected to the downward motion information collection unit, and the elastic pressure generated by the elastic support structure being squeezed by the force-applying structure can act on the downward motion information collection unit.

[0021] The downward action information collection unit is reasonably set so that when the force-applying structure moves downward, the downward action information collection unit can be triggered in time.

[0022] In some implementations, the downward motion information collection unit is a switch structure.

[0023] The switch structure can be triggered quickly, which is conducive to the timely collection of downward movement information of the force-applying structure.

[0024] In some implementations, the lock body includes an elastic component for resetting the lock tongue, and the elastic supporting structure is the elastic component of the lock body.

[0025] By using the elastic supporting structure as an elastic component for resetting the lock body, the number of parts can be reduced.

[0026] In some implementations, the force-applying structure is rotationally connected to the locking tongue structure, and the signal acquisition unit includes a rotation signal acquisition unit, which is used to acquire a rotation signal of the force-applying structure.

[0027] By collecting the rotation signal of the force-applying structure, the interface of the foldable mobile phone can be operated, providing a new way of human-machine interaction.

[0028] In some implementations, the locking device includes a transmission mechanism connected to a force-applying structure, the transmission mechanism includes an end detection disk, and when the force-applying structure rotates, the end detection disk can be driven to rotate, and the rotation signal acquisition unit is used to collect the rotation signal of the end detection disk.

[0029] By setting the transmission mechanism, the rotation signal acquisition unit is not limited to being set near the force-applying structure, and the position setting of the rotation signal acquisition unit is more flexible through the setting of the transmission mechanism.

[0030] In some implementations, the transmission mechanism further includes a driving gear, which is disposed at the bottom end of the force-applying structure and can prevent the force-applying structure from detaching upward from the locking tongue structure.

[0031] Using the driving gear as the upward anti-slip structure can simplify the number of parts and avoid adding an external upward anti-slip structure; in addition, the transmission mechanism is gear transmission, and the transmission is precise.

[0032] In some implementations, the rotation signal acquisition unit includes a signal transmitter and a signal receiver, and the signal transmitter and the signal receiver are arranged on one side of the end detection disk along the thickness direction of the end detection disk, or the signal transmitter and the signal receiver are arranged on one side of the circumferential direction of the end detection disk; the end detection disk is a gear, or the end detection disk is an annular or disc-shaped boss coaxially arranged on the gear.

[0033] According to the distribution of various components inside the mobile phone, the position of the rotation signal acquisition unit is reasonably arranged to make the internal structure of the mobile phone compact, so as to reduce the size of the mobile phone; and for the terminal detection disk, the terminal detection disk can also be set as a gear or a ring-shaped or disc-shaped boss coaxially arranged on the gear according to the convenience of detection.

[0034] In some implementations, the circumferential side surface of the top of the force-applying structure forms a hand-held rotating surface, and when the locking device is installed on the folding terminal, the hand-held rotating surface is exposed outside the folding terminal.

[0035] By setting the hand-held rotating surface to be exposed outside the folding terminal, it is convenient for the user to rotate the force-applying structure; of course, the height of the force-applying structure protruding from the main frame of the folding mobile phone should not be too small, otherwise it is inconvenient for the user to apply force, and should not be too large, otherwise it affects the appearance.

[0036] A second aspect of the present application provides a folding terminal, comprising a main frame, a sub-frame, a control device and a locking device, wherein a locking body of the locking device is arranged on the main frame, and a signal acquisition unit of the locking device is electrically connected to the control device.

[0037] Through the above technical solution, since the foldable terminal includes the above locking device, it at least has all the beneficial effects of the locking device, which will not be described in detail here.

[0038] A third aspect of the present application provides a control method for operating a foldable terminal using a locking device, comprising: acquiring action information of a locking body; and identifying the action information as an operation instruction of the foldable terminal.

[0039] The locking device can not only realize the locking of the main frame and the sub-frame of the folding terminal, but also operate the folding mobile phone interface by operating the locking device, so as to increase the function of the locking device and provide a new human-machine interaction mode.

[0040] In some implementations, it specifically includes: acquiring a downward motion signal of the lock body; and identifying the downward motion signal as an operation instruction to enter a target application.

[0041] Since the pressing force structure is a short-time action, the recognition of the downward action signal is used as an operation instruction to enter the target application.

[0042] In some implementations, the target application is a versatile wallet.

[0043] The Variety Wallet is specially designed for use when the mobile phone is in a folded state to increase the original beauty of the mobile phone in the folded state. Therefore, the target application is preferably the Variety Wallet, so that when the folded mobile phone operates the locking device, the Variety Wallet is entered at the same time, and the mobile phone interface displays the wallpaper in the Variety Wallet.

[0044] In some implementations, it specifically includes: acquiring a rotation signal of the lock body; and identifying the rotation signal as an operation instruction of the current interface.

[0045] The function of rotating the force-applying structure is added to realize further operation of the mobile phone interface and provide a new way of human-computer interaction.

[0046] In some implementations, depending on the application displayed on the current interface, the operation instruction is a volume adjustment instruction, a page turning instruction, a fast forward / rewind instruction, an up and down sliding instruction, a page zoom in and out instruction, an application switching instruction, a lens zoom in and out instruction, or an input box option switching instruction.

[0047] By rotating the force-applying structure, different applications can be operated, which is convenient and adds new experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0087] See also Figure 1-Figure 2 , Figure 1 A schematic diagram of the structure of an existing foldable mobile phone in an unfolded state; Figure 2 It is a structural schematic diagram of an existing foldable mobile phone in a folded state.

[0088] See also Figure 1 , is an existing folding mobile phone 1 with an external folding screen. The external folding screen mobile phone generally includes a display screen, a main frame 12, a sub-frame 13, and a hinge, etc. The main frame 12 and the sub-frame 13 are connected by a hinge so as to be folded and unfolded around the hinge. The display screen is a bendable flexible display screen, see Figure 1 , fold along the direction of the arrow in the figure, and you can get Figure 2 Schematic diagram showing the folded state.

[0089] See also Figure 1 The main frame 12 is provided with a protruding portion 14, which is parallel to the folding axis of the mobile phone, and the button and the lock 11 are provided on the protruding portion 14. In addition to the button and the lock 11, other structures are also provided in the protruding portion 14, such as a camera. The sub-frame 13 is provided with a slot, which is provided at the edge of the sub-frame 13 parallel to the folding axis of the mobile phone. Figure 2 , illustrates a schematic diagram of the foldable mobile phone 1 in a folded state, at which time the edge of the sub-frame 13 parallel to the folding axis is close to the edge of the protruding portion 14.

[0090] In order to prevent the secondary frame 13 from automatically opening after the main frame 12 and the secondary frame 13 are folded, a button and a lock buckle 11 are designed. When no external force is applied to the button, the lock tongue portion 118 protrudes from the main frame 12. Figure 1 , showing the locking tongue portion 118. When the button is pressed downward, the locking tongue portion 118 can be retracted into the main frame 12. Press the button and fold the main frame 12 and the sub-frame 13 of the mobile phone so that the main frame 12 and the sub-frame 13 are folded as shown in FIG. Figure 2 As shown, the button is released again, and the locking tongue portion 118 is reset under the action of elastic force, extends out of the main frame 12 and is inserted into the slot on the sub-frame 13, thereby achieving the engagement between the main frame 12 and the sub-frame 13, preventing the sub-frame 13 from tilting upward when folded onto the main frame 12 and affecting the user's use of the mobile phone.

[0091] In existing external folding screen mobile phones, the buttons and locks 11 thereon only have the function of locking the main frame 12 and the sub-frame 13, and have no other functions, resulting in the buttons and locks having relatively simple functions.

[0092] See also Figure 3-Figure 7 , Figure 3 It is a schematic diagram of the structure of buttons and locks in an existing folding mobile phone; Figure 4 It is a top view schematic diagram of buttons and locks in an existing folding mobile phone; Figure 5 yes Figure 4 AA section view; Figure 6 It is a schematic diagram of the main view of buttons and locks in an existing folding mobile phone; Figure 7 yes Figure 6 Schematic diagram of the cross-section along the BB axis.

[0093] The button and lock 11 include a button 111 and a lock, see Figure 5 and Figure 7 , the button 111 passes through the inner bracket 15 and is connected to the lock. The lock includes a lock movement unit 112, a lock tongue unit 113, a roller 114 and an elastic member 115. The button 111 vertically passes through the lock movement unit 112 and can be fixed on the lock movement unit 112. The lock tongue unit 113 is provided with a receiving hole 119, and the lock movement unit 112 is arranged in the receiving hole 119. The roller 114 passes through the lock movement unit 112 horizontally and the two ends of the roller 114 are rotatably connected to the lock tongue unit 113. The lock tongue unit 113 also includes a lock tongue portion 118 arranged on one side, and the lock tongue unit 113 is connected to the elastic member 115.

[0094] See also Figure 5 The lock movement unit 112 is provided with a through hole 116 with a triangular cross section, the upper side of the through hole 116 is an inclined surface, and the roller 114 is inserted into the through hole 116. When the button 111 is not pressed, under the action of the rightward elastic force of the elastic member 115, see Figure 5, the roller 114 is located on the right side of the through hole 116. When the button 111 is pressed downward, the lock movement unit 112 moves downward with the button 111, and the upper inclined surface of the through hole 116 squeezes the roller 114, so that the roller 114 moves to the left, driving the lock tongue unit 113 to move to the left, so that the lock tongue portion 118 can be retracted into the main frame 12, and at this time the elastic member 115 is in a further compressed state; when the downward pressure on the button 111 is cancelled, under the action of the elastic force of the elastic member 115, the lock tongue unit 113 moves back to the right, so that the lock tongue portion 118 can extend out of the main frame 12, and the upper inclined surface of the through hole 116 squeezes the roller to make the lock movement unit 112 move upward, thereby realizing the reset of the lock.

[0095] The elastic member 115 is usually a spring. Figure 7 , it is shown that two limiting rods 117 are arranged on the lock tongue unit 113, and each limiting rod 117 is sleeved with an elastic member 115, and the limiting rod 117 is used to limit the position of the elastic member 115 so that it is compressed along the axis direction of the limiting rod 117. One end of the elastic member 115 is connected to the lock tongue unit 113, and the other end of the elastic member 115 is connected to other structures in the main frame 12, so that when the lock tongue unit 113 moves to the left, the elastic member 115 can be further compressed.

[0096] The button and lock buckle 11 of the above structure realize that when the button 111 is pressed downward, the lock tongue portion 118 retracts into the main frame 12, and when the button 111 is no longer pressed downward, the lock tongue portion 118 extends out of the main frame 12. The button and lock buckle 11 can only realize the function of engaging the main frame 12 and the sub-frame 13, and have no other functions.

[0097] In order to solve the above problems, the present application provides a locking device, which can not only realize the snap-fit ​​locking between the main frame 12 and the sub-frame 13 of the folding terminal, but also, by operating the locking device, the interface of the folding mobile phone can be operated to increase the function of the locking device, provide a new human-machine interaction mode, and can replace some buttons of the folding mobile phone (such as volume buttons), simplify the structure of the folding mobile phone shell, and help improve the consistency of the appearance of the folding screen mobile phone.

[0098] The above gives an embodiment of the existing button and lock 11. The application of this application is not limited to the lock structure that can only replace the above structure. Other lock structures that can realize the engagement of the main frame 12 and the sub-frame 13 of the folding terminal can be replaced by the lock device provided by this application.

[0099] The locking device provided in the present application is not limited to use in folding mobile phones. Other folding terminals such as laptops, tablet computers, personal digital assistants or vehicle-mounted equipment can also use the locking device provided in the present application.

[0100] The locking device 2 provided in the embodiment of the present application is explained in detail below in conjunction with the accompanying drawings.

[0101] A locking device 2 includes: a locking body and a signal acquisition unit, the locking body includes a force-applying structure 21 and a lock tongue structure 22, the force-applying structure 21 is connected to the lock tongue structure 22, and a lock tongue 225 on the lock tongue structure 22 can be moved in a retracted direction by applying force to the force-applying structure 21; the signal acquisition unit is used to collect action information of the locking body for operating a folding terminal.

[0102] The lock body is used to complete the locking function when the main frame and the sub-frame of the foldable mobile phone are folded. When the user operates the lock device 2, a force is applied to the force structure 21, and the force structure 21 acts on the lock tongue structure 22, so that the lock tongue 225 moves in the direction of retraction. When the force applied to the force structure 21 is cancelled, the lock tongue structure 22 is reset under the action of the elastic component. The signal acquisition unit is used to collect the action information of the lock body, and can realize the operation of the foldable mobile phone interface, so as to increase the function of the lock device 2 and provide a new human-machine interaction mode.

[0103] The signal acquisition unit collects the action information of the lock body and transmits the action information to the control device of the folding mobile phone. The control device outputs the mobile phone interface operation instructions according to the action information.

[0104] Because both the force-applying structure 21 and the lock tongue structure 22 can move, the signal acquisition unit can collect the movement information of the force-applying structure 21 and the movement information of the lock tongue structure 22. Of course, the movement information of the force-applying structure 21 and the lock tongue structure 22 can also be collected at the same time.

[0105] For example, the signal acquisition unit can collect the action information of the lock tongue, specifically: when the mobile phone needs to be folded, force is applied to the force structure 21, and the lock tongue 225 retracts into the main frame. At this time, the signal acquisition unit collects the action information of the lock tongue retracting. After the main frame and the sub-frame are folded, the force acting on the force structure 21 is canceled, and the lock tongue is reset and inserted into the sub-frame. At this time, the signal acquisition unit collects the action information of the lock tongue extending.

[0106] For example, when the lock body moves, you can enter the Baibian Wallet, so that the mobile phone interface displays the wallpaper in the Baibian Wallet. That is, the lock body moves, the signal acquisition unit collects the action information of the lock body, and transmits the collected information to the mobile phone control device, which uses it as an operation instruction to enter the Baibian Wallet and control the entry into the Baibian Wallet application.

[0107] Regarding the operation of the mobile phone when the lock body is in action, the specific application scenarios are described in detail below and will not be repeated here.

[0108] In one embodiment, the signal acquisition unit includes a downward motion information acquisition unit, and the downward motion information acquisition unit is used to collect information when the lock body moves downward.

[0109] Usually, when the lock body moves, there is a component that moves downward, and the downward movement information collection unit collects the movement information of the component that moves downward, for example, see Figure 5 and Figure 7 When the button 111 is pressed, both the button 111 and the lock motion unit 112 will move downward, so the motion information of any of these components can be collected.

[0110] In one embodiment, the downward action information collection unit is a pressure signal collection unit, and when the lock body moves downward, force can be applied to the pressure signal collection unit.

[0111] For example, when the lock body moves downward, if the lock body moves downward to the maximum extent, force is applied to the pressure signal acquisition unit. The pressure signal acquisition unit collects information about the downward movement of the lock body and generates a signal.

[0112] Preferably, the pressure signal acquisition unit is disposed below the force-applying structure 21 , that is, when the user applies a downward pressing force to the force-applying structure 21 , the force-applying structure 21 applies force to the pressure signal acquisition unit during the downward movement.

[0113] The pressure signal acquisition unit is a signal generated by applying force thereon. Of course, the downward motion information acquisition unit is not limited to being a pressure signal acquisition unit. For example, the downward motion information acquisition unit can be set as a distance measuring device, and the distance measuring device is set below the lock body. By measuring the distance between the lock body and the distance measuring device, the signal of the downward motion of the lock body is collected, and when it is detected that the distance between the lock body and the distance measuring device is within the set range value, the folding mobile phone outputs an operation instruction.

[0114] In one embodiment, the position of the force-applying structure 21 on the lock tongue structure 22 along the height direction is adjustable, a pressing surface is formed on the force-applying structure 21, and a pressed surface is formed on the lock tongue structure 22, which is located below the pressing surface and directly opposite to the pressing surface. When the force-applying structure 21 is actuated to cause the downward action information collection unit to generate a signal, there is a gap between the pressing surface and the pressed surface.

[0115] That is, when the force-applying structure 21 moves downward a small amount, the downward action information collection unit can generate a signal, and the force-applying structure 21 does not apply force to the lock tongue structure 22, that is, there is a gap between the pressing surface on the force-applying structure 21 and the pressed surface on the lock tongue structure 22; when the force-applying structure 21 moves downward a large amount, the pressing surface on the force-applying structure 21 contacts the pressed surface on the lock tongue structure 22, and the force-applying structure 21 applies force to the lock tongue structure 22, so that the lock tongue 225 of the lock tongue structure 22 can move in the direction of retracting the main frame. A scenario in which only the downward action information collection unit generates a signal without the lock tongue structure 22 moving can be realized.

[0116] The position of the force-applying structure 21 on the lock tongue structure 22 along the height direction can be adjusted. A fixing piece can be set below the force-applying structure 21. The fixing piece is provided with a threaded hole and the force-applying structure 21 is inserted into the threaded hole on the fixing piece and is threadedly connected with the fixing piece. The downward action information collection unit can be set as a distance measuring device. When the force-applying structure 21 is rotated so that the force-applying structure 21 moves downward by a small displacement, the downward action information collection unit can generate a signal; when the force-applying structure 21 continues to rotate, the pressing surface on the force-applying structure 21 contacts the pressed surface on the lock tongue structure 22, and the force-applying structure 21 applies force to the lock tongue structure 22, so that the lock tongue 225 of the lock tongue structure 22 can move in the direction of retracting the main frame. When the force-applying structure 21 rotates in the opposite direction to reset, the lock tongue structure 22 is reset under the action of its own elastic member.

[0117] Regarding the adjustable position of the force-applying structure 21 on the lock tongue structure 22 in the height direction, in one embodiment, an elastic support structure 26 is provided below the force-applying structure 21, and the force-applying structure 21 is supported on the elastic support structure 26. When a small pressure is applied to the force-applying structure 21 (for example, a force less than 1N), the elastic support structure 26 is compressed a small amount, the force-applying structure 21 moves a small amount downward, and only the downward action information acquisition unit is triggered to generate a signal, while the lock tongue structure 22 does not move. When a large pressure is applied to the force-applying structure 21 (for example, a force greater than 1N), the force-applying structure 21 moves a large amount downward, the elastic support structure 26 is compressed a large amount, the downward action information acquisition unit is triggered to generate a signal first, and then the lock tongue 225 of the lock tongue structure 22 retracts into the main frame. In addition, in this embodiment, the downward action information acquisition unit can be a pressure signal acquisition unit, the elastic support structure 26 is connected to the pressure signal acquisition unit, and the elastic pressure generated by the elastic support structure 26 being squeezed by the force-applying structure 21 can act on the pressure signal acquisition unit.

[0118] For example, the position of the pressure signal acquisition unit is fixed, and the elastic support structure 26 is arranged between the pressure signal acquisition unit and the force-applying structure 21. When the force-applying structure 21 moves downward to squeeze the elastic support structure 26, the pressure signal acquisition unit can generate a signal. Of course, one end of the elastic support structure 26 can also be fixed, and the pressure signal acquisition unit can be arranged between the elastic support structure 26 and the force-applying structure 21.

[0119] In one embodiment, the lock body includes an elastic component for resetting the lock tongue, and the elastic supporting structure 26 is the elastic component of the lock body.

[0120] When an elastic support structure 26 is disposed below the force-applying structure 21 , if the pressing force on the force-applying structure 21 is canceled, the lock body can be reset under the elastic force of the elastic support structure 26 , so there is no need to add other elastic structures in the lock body.

[0121] In one embodiment, the downward action information collection unit is a switch structure 24, which includes a contact end. When the force-applying structure 21 moves downward, the contact end of the switch structure 24 is squeezed by force, and the switch structure 24 is turned on, thereby enabling the switch structure 24 to generate a signal to transmit the folding mobile phone control device, so that the control device outputs instructions to operate the mobile phone.

[0122] Preferably, the switch structure 24 is arranged on a circuit board, and the circuit board is connected to the control device of the folding terminal. Alternatively, the switch structure 24 may not be arranged directly on the circuit board, but the position of the switch structure 24 may be fixed and connected to other circuit boards of the folding terminal through wires.

[0123] Preferably, the downward motion information collection unit is a switch structure 24, but is not limited to being only the switch structure 24. For example, the downward motion information collection unit can be set as a pressure sensor. When the elastic support structure 26 is set between the pressure signal collection unit and the force-applying structure 21, when the structure is not pressed, the pressure sensor detects a pressure signal. When the force-applying structure 21 moves downward, the pressure detected by the pressure sensor increases, thereby generating a pressure enhancement signal, which is transmitted to the control device of the folding mobile phone, and the control device issues a command to operate the mobile phone.

[0124] When the downward motion information acquisition unit is a switch structure 24, the switch structure 24 is preferably a micro switch, so that when the force-applying structure 21 is pressed with a small force, the switch structure 24 can be triggered.

[0125] Alternatively, when the downward action information collection unit is a switch structure, the structure of the downward action information collection unit may also be as follows: the switch structure 24 includes a circuit board and a spring sheet, the spring sheet is arranged on the circuit board, the elastic support structure 26 is arranged between the spring sheet and the force-applying structure 21, and contacts are arranged on the circuit board. The bottom surface of the force-applying structure 21 is a conductive surface and is connected to the ground signal. When the force-applying structure 21 moves downward so that the spring sheet is squeezed and contacts with the circuit board contacts, the circuit can be turned on and the signal can be transmitted to the control device of the mobile phone.

[0126] Regarding the elastic structure, the elastic member that can be compressed and deformed in the elastic structure can be a spring. Of course, the elastic member that can be compressed and deformed in the elastic structure is not limited to only a spring, and can also be other elastically compressible parts.

[0127] In one embodiment, the force-applying structure 21 includes a top cap 211, a connecting shaft 212, and a limiting end 213. The connecting shaft 212 passes through an assembly hole of the locking tongue structure 22. The length of the assembly hole is less than the length of the connecting shaft 212. The top and bottom of the connecting shaft 212 are respectively provided with a top cap 211 and a limiting end 213. The top cap 211 and the limiting end 213 limit the connecting shaft 212 on the locking tongue structure 22. The elastic support structure 26 is arranged below the limiting end 213.

[0128] The cross-sectional areas of the top cap 211 and the limiting end 213 are larger than the cross-sectional area of ​​the force-applying structure 21. The maximum upward movement distance of the force-applying structure 21 relative to the locking tongue structure 22 is when the limiting end 213 contacts the bottom surface of the locking tongue structure 22, and the maximum downward movement distance is when the top cap 211 contacts the top surface of the locking tongue structure 22. The limiting end 213 is supported on the elastic support structure 26. The force-applying structure 21 described above has a simple structure.

[0129] The hole diameter of the connecting shaft 212 is not larger than the hole diameter of the assembly hole, so that the position of the force-applying structure 21 on the locking tongue structure 22 along the height direction can be adjusted. As for the shape of the connecting shaft 212, the cross section is preferably circular, of course, the shape of the cross section is not limited to a circle, for example, the shapes of the connecting shaft 212 and the assembly hole are both polygonal, in which case the connecting shaft 212 cannot rotate relative to the locking tongue structure 22.

[0130] In one embodiment, the top cap 211 includes a cap body 2111 and a pressing body 2112, the pressing body 2112 is connected to the bottom of the cap body 2111, the cross-sectional area of ​​the pressing body 2112 is larger than the cross-sectional area of ​​the assembly hole and smaller than the cross-sectional area of ​​the cap body 2111, and the bottom surface of the pressing body 2112 forms a pressing surface.

[0131] By making the cross-sectional area of ​​the pressing body 2112 smaller than the cross-sectional area of ​​the cap body 2111 , the contact area between the user's finger and the force-applying structure 21 is increased, making it easier for the user to press the force-applying structure 21 .

[0132] See also Figure 8-Figure 11 , Figure 8 is a simplified longitudinal cross-sectional view of the locking device (the force-applying structure is not in a pressed state); Fig. 9 It is a simplified longitudinal cross-sectional view of the switch structure in the locking device in a triggered state; Fig.10 is a simplified longitudinal cross-sectional view of the locking bolt in the locking device in a retracted state; Fig.11 The process of collecting the action signal of the force-applying structure 21 by the downward action information collection unit is described in detail as follows in conjunction with the accompanying drawings:

[0133] See also Fig.10 , schematically shows the force-applying structure 21, the limit end 213 is supported on the elastic support structure 26, a switch structure 24 (downward action information collection unit) is arranged under the elastic support structure 26, the switch structure 24 is fixed in position, the connecting shaft 212 passes through the assembly hole on the lock tongue structure 22, the diameter of the connecting shaft 212 is smaller than the diameter of the assembly hole, and there is a gap L between the pressing body 2112 of the top cap 211 and the upper end surface of the lock tongue structure 22 (at this time, no force is applied to the force-applying structure 21).

[0134] See also Fig.11 The lock tongue structure 22 includes a lock moving part 221, a lock tongue part 222, and a roller part 223. The connecting shaft 212 vertically passes through the lock moving part 221. The lock tongue part 222 is provided with a receiving hole. The lock moving part 221 is provided in the receiving hole. The roller part 223 horizontally passes through the lock moving part 221 and both ends of the roller part 223 are rotatably connected with the lock moving part 221. The lock tongue part 222 is provided with a lock tongue 225. Fig.11 The lock moving part 221 is provided with a plug hole 224 with a triangular cross section, the upper side surface of the plug hole 224 is an inclined surface, and the roller part 223 is inserted into the through hole.

[0135] When a small force is applied to press the cap body 2111, the switch structure 24 is turned on to generate a signal. At this time, the force-applying structure 21 moves downward by d, see Fig. 9 At this time, there is a gap Ld between the pressing body 2112 of the top cap 211 and the upper end surface of the lock moving part 221, and the roller part 223 is located on the right side of the insertion hole 224. When the cap body 2111 is pressed down further, the lock tongue 225 on the lock tongue part 222 can be retracted. Fig.10, is a longitudinal cross-sectional view of the lock device 2 when the lock tongue 225 is in a retracted state. It can be seen from the figure that the roller component 223 is located on the left side of the insertion hole 224. When the pressure on the force-applying structure 21 is canceled, the force-applying structure 21 and the lock tongue structure 22 are reset under the action of the elastic support structure 26. After the force-applying structure 21 is reset, the pressure on the switch structure 24 is reduced, and the switch structure 24 is opened and presents a non-conductive state.

[0136] When the cap body 2111 is not pressed, under the action of the elastic force of the elastic support structure 26, Figure 8 The roller component 223 is located on the right side of the insertion hole 224. When the cap body 2111 is pressed downward, the lock moving component 221 moves downward together with the force-applying structure 21. The upper inclined surface of the insertion hole 224 squeezes the roller component 223, causing the roller component 223 to move to the left, driving the lock tongue component 222 to move to the left, so that the lock tongue 225 can be retracted into the main frame.

[0137] In one embodiment, the force-applying structure 21 is rotatably connected to the lock tongue structure 22, and the signal acquisition unit includes a rotation signal acquisition unit 25, which is used to collect the rotation signal of the force-applying structure 21. In this embodiment, the signal acquisition unit also includes the downward action information acquisition unit. In another embodiment, the force-applying structure 21 is rotatably connected to the lock tongue structure 22, and the signal acquisition unit only includes the rotation signal acquisition unit 25, but does not include the downward action information acquisition unit.

[0138] The rotation signal acquisition unit 25 acquires the rotation information of the force-applying structure 21 and transmits the rotation information to the control device of the foldable mobile phone, and the control device outputs the mobile phone interface operation instructions according to the rotation information. For example, the volume can be controlled by rotating the force-applying structure 21. When rotating clockwise, the volume of the mobile phone gradually increases, and when rotating counterclockwise, the volume of the mobile phone gradually decreases. In this way, the volume adjustment button on the mobile phone can be cancelled, simplifying the structure of the mobile phone.

[0139] In addition, by rotating the force-applying structure 21, it is not limited to adjusting the volume, but can also realize other operations on the currently displayed page of the mobile phone. For specific other application scenarios, please refer to the description of the method below, which will not be elaborated here.

[0140] In one embodiment, the circumferential side surface of the top of the force-applying structure 21 forms a hand-held rotating surface. When the locking device 2 is installed on the folding mobile phone, the hand-held rotating surface is exposed outside the folding mobile phone. Preferably, anti-slip grooves are provided on the hand-held rotating surface.

[0141] Since the force-applying structure 21 needs to be rotated, it is best to set the force-applying structure 21 to protrude from the main frame of the folding mobile phone by a certain height, so that the circumferential outer side surface of the protruding part of the force-applying structure 21 forms a hand-held rotating surface, and the user can use the index finger and thumb to act on the hand-held rotating surface to rotate the force-applying structure 21. Currently, the buttons on the folding mobile phone almost do not protrude from the main frame of the folding mobile phone, making it difficult to apply force to the circumferential outer side surface of the force-applying structure 21.

[0142] The height of the force-applying structure 21 protruding from the main frame of the foldable mobile phone should not be too small, otherwise it is inconvenient for the user to apply force, and should not be too large, otherwise it affects the appearance.

[0143] In one embodiment, the locking device 2 includes a transmission mechanism 23, which is connected to the force-applying structure 21. The transmission mechanism includes an end detection disk. When the force-applying structure 21 rotates, it can drive the end detection disk to rotate. The rotation signal acquisition unit 25 is used to collect the rotation signal of the end detection disk.

[0144] When the force-applying structure 21 rotates, the transmission mechanism 23 is activated, and the terminal detection disk also rotates synchronously with the force-applying structure 21, so that the rotation information of the terminal detection disk can be collected. By setting the transmission mechanism 23, it is convenient to arrange the position of the rotation signal collection unit 25 according to the situation of the internal space of the mobile phone. Of course, the locking device 2 may not include the transmission mechanism 23, that is, the rotation signal collection unit 25 directly collects the rotation information of the force-applying structure 21.

[0145] In one embodiment, the transmission mechanism 23 further includes a driving gear 231, which is disposed at the bottom end of the force-applying structure 21 and can prevent the force-applying structure 21 from upwardly separating from the locking tongue structure 22. That is, the driving gear 231 can not only be used for transmission, but also serve as the limiting end 213 of the force-applying structure 21.

[0146] In one embodiment, the transmission mechanism 23 includes a driving gear 231 and a driven gear 232. The driving gear 231 is fixed to the bottom end of the force-applying structure 21, and the driven gear 232 is meshed with the driving gear 231. A rotating shaft is provided on the driven gear 232, and the rotating shaft can be fixed by a bearing seat.

[0147] Since the driving gear 231 needs to move up and down, it is preferred that there is a small gap between the driving gear 231 and the driven gear 232 so that the driving gear 231 can move up and down relative to the driven gear 232 .

[0148] In addition, since the driving gear 231 needs to move up and down, and the driving gear 231 and the driven gear 232 need to always remain in meshing, it is preferred to set the thickness of the driven gear 232 to be greater than the thickness of the driving gear 231, and the thickness value of the driven size is not less than the sum of the thickness of the driving gear 231 and the maximum downward stroke of the force-applying structure 21.

[0149] In the above embodiment, the transmission mechanism 23 includes a driving gear 231 and a driven gear 232, that is, the transmission mechanism is a gear structure, and the gear structure has accurate transmission. The number of gears in the transmission mechanism 23 is not limited to two, and more gears can be set, but if two gears meet the layout of the rotation signal acquisition unit 25 in the mobile phone frame, it is preferred to set two to reduce the number of parts.

[0150] In one embodiment, the rotation signal acquisition unit 25 includes a signal transmitter and a signal receiver, and the signal transmitter and the signal receiver are arranged on one side of the end detection disk along the thickness direction of the end detection disk, or the signal transmitter and the signal receiver are arranged on one side of the circumferential direction of the end detection disk.

[0151] The signal transmitter emits light, which may be infrared light but is not limited to infrared light. The light generated by the signal transmitter is reflected by the terminal detection disk and then emitted to the signal receiver. The rotation information of the terminal detection disk is collected through the signal received by the signal receiver.

[0152] Regarding the positions of the signal transmitter and the signal receiver, they can be set on one side in the thickness direction of the end detection disk, or they can be set on one side along the circumferential direction of the end detection disk. According to the internal structure of the main frame of the mobile phone, the specific positions of the signal transmitter and the signal receiver can be reasonably set.

[0153] In one embodiment, the end detection disk is a gear, or the end detection disk is an annular or disc-shaped boss 233 coaxially arranged on the gear.

[0154] Taking the embodiment in which the transmission mechanism 23 includes a driving gear 231 and a driven gear 232 as an example, the driven gear 232 can be used as an end detection disk, see Fig.12 , schematically illustrating that the rotation signal acquisition unit 25 is disposed below the driven gear 232 , that is, the rotation signal acquisition unit 25 is disposed on one side of the driven gear 232 in the thickness direction.

[0155] Taking the embodiment in which the transmission mechanism 23 includes a driving gear 231 and a driven gear 232 as an example, an annular or disc-shaped boss 233 may be provided on the end surface of the driven gear 232, and the boss 233 serves as an end detection disk. Fig. 22 2 shows an annular boss, the hole on the boss 233 is used to avoid the rotating shaft, and the rotation signal acquisition unit 25 is arranged on one side of the boss 233 along the thickness direction. Fig.23, a disc-shaped boss is schematically shown, and the rotation signal acquisition unit 25 is arranged on one side of the boss 233 along the circumferential direction.

[0156] See also Figure 12-14 , Fig.12 is a simplified longitudinal cross-sectional view of the locking device (the force-applying structure is not in a pressed state); Fig.13 It is a simplified longitudinal cross-sectional view of the switch structure in the locking device in a triggered state; Fig.14 It is a longitudinal cross-sectional diagram of the locking tongue in the lock device in a retracted state. In conjunction with the accompanying drawings, the process of the downward action information acquisition unit and the rotation signal acquisition unit 25 collecting the action signal of the force-applying structure 21 is described in detail as follows:

[0157] See also Fig.12 , schematically shows the force-applying structure 21, the driving gear 231 (limiting end 213) is supported on the elastic supporting structure 26, a switch structure 24 (downward action information acquisition unit) is arranged under the elastic supporting structure 26, the switch structure 24 is fixed in position, the connecting shaft 212 passes through the assembly hole on the lock tongue structure 22, the diameter of the connecting shaft 212 is smaller than the diameter of the assembly hole, and there is a gap L between the pressing body 2112 of the top cap 211 and the upper end surface of the lock tongue structure 22.

[0158] The specific structure of the lock tongue structure 22 can be found in Fig.11 As well as the above Fig.11 I will not go into details about the text description here.

[0159] See also Fig.13 When a small force is applied to press the cap body 2111, the switch structure 24 is turned on to generate a signal. At this time, the force-applying structure 21 moves downward by d (the driving gear 231 moves downward relative to the driven gear 232), and there is a gap Ld between the pressing body 2112 of the top cap 211 and the upper end surface of the lock tongue structure 22. Fig.14 When the cap body 2111 is continuously pressed downward, the lock tongue 225 on the lock tongue component 222 can be retracted. When the pressure on the force-applying structure 21 is canceled, the force-applying structure 21 and the lock tongue structure 22 are reset under the action of the elastic support structure 26. After the force-applying structure 21 is reset, the pressure on the switch structure 24 is reduced, and the switch structure 24 is opened to a non-conducting state.

[0160] The force applying structure 21 is rotated without pressing downward, the force applying structure 21 rotates and the elastic supporting structure 26 does not rotate, the driving gear 231 rotates, and then drives the driven gear 232 to rotate, and the rotation signal acquisition unit 25 collects the rotation information of the driven gear 232 at this time.

[0161] See also Figure 15-16 , Fig.15It is a simplified longitudinal cross-sectional view of the locking device (the force-applying structure is not in a pressed state and the force-applying structure can be rotated); Fig.16 The longitudinal cross-sectional diagram of the locking tongue in the locking device is in a retracted state. In conjunction with the accompanying drawings, the process of the rotation signal acquisition unit 25 collecting the action signal of the force-applying structure 21 is described in detail as follows:

[0162] See also Fig.15 , schematically illustrates a force-applying structure 21, which is rotatably connected to the lock tongue structure 22. However, at this time, the height of the force-applying structure 21 relative to the lock tongue structure 22 cannot be adjusted. A driving gear 231 is provided at the bottom of the force-applying structure 21, and a driven gear 232 is meshed with the driving gear 231. The rotation signal acquisition unit 25 acquires the rotation information of the driven gear 232.

[0163] The force applying structure 21 is rotated, the driving gear 231 is rotated, and then the driven gear 232 is driven to rotate. The rotation signal acquisition unit 25 collects the rotation information of the driven gear 232 at this time. Fig.16 When the force-applying structure 21 is pressed downward, the force-applying structure 21 acts on the lock tongue structure 22, so that the lock tongue 225 on the lock tongue component 222 can be retracted. When the pressure on the force-applying structure 21 is released, the lock tongue structure 22 is reset under the action of its own elastic member.

[0164] See also Figure 17-Figure 21 , only the specific structural schematic diagram of the locking device 2 under the rotation signal is collected. Fig.17 is a schematic diagram of the front structure of the locking device; Fig.18 is a schematic diagram of the back structure of the locking device; Fig.19 is a top view schematic diagram of a locking device; Fig. 20 yes Fig.19 A CC-direction cross-sectional schematic diagram; Fig.21 It is a front view schematic diagram of the locking device.

[0165] See also Fig. 20 , schematically shows a force-applying structure 21, which is rotatably connected to the lock tongue structure 22, but at this time the height of the force-applying structure 21 relative to the lock tongue structure 22 cannot be adjusted, a driving gear 231 is provided at the bottom of the force-applying structure 21, and the connecting shaft 212 of the force-applying structure 21 is limited on the lock tongue structure 22 through the top cap 211 and the driving gear 231. The driven gear 232 is meshed with the driving gear 231, and the rotation signal acquisition unit 25 acquires the rotation information of the driven gear 232. The lock tongue structure 22 can be seen in Figure 7 As well as the above Figure 7 The text description is not repeated here.

[0166] The present application provides a folding terminal, comprising a main frame, a sub-frame, a control device and a locking device 2, wherein a locking body of the locking device 2 is arranged on the main frame, and a signal acquisition unit of the locking device 2 is electrically connected to the control device.

[0167] Regarding the locking device 2, the specific structure and effect have been described above and will not be repeated here.

[0168] When external force is applied to the lock device 2, the signal collection unit of the lock device 2 collects the action information of the lock body and sends the collected information to the control device. The control device issues instructions for mobile phone interface operations according to the received signal.

[0169] When operating the locking device 2, not only can the main frame and the sub-frame be locked, but also the folding mobile phone interface can be operated by operating the locking device 2, so that the folding terminal can provide a new human-machine interaction mode. For details about the operation of the mobile phone interface by the action of the locking device 2, please refer to the description of the method below, and no further details will be given here.

[0170] Foldable terminals include but are not limited to foldable mobile phones, laptop computers, tablet computers, personal digital assistants or car-mounted devices.

[0171] See also Fig.24 The present application provides a control method for operating a folding terminal using a locking device 2, comprising:

[0172] Step S1, obtaining the action information of the lock body;

[0173] Step S2: Identify the action information as an operation instruction for folding the terminal.

[0174] Obtain the action information of the lock body, and use the signal acquisition unit in the lock device 2 to obtain the action information of the lock body; identify the action information as the operation instruction of the folding terminal, and the signal acquisition unit transmits the collected action information to the control device of the folding terminal. The control device identifies the action information and then issues a corresponding operation instruction.

[0175] In one embodiment, the method specifically includes: obtaining a downward motion signal of the lock body; and identifying the downward motion signal as an operation instruction to enter a target application.

[0176] Obtain the downward action signal of the lock body, and use the signal acquisition unit in the lock device 2 to obtain the downward action signal of the lock body; identify the downward action signal as an operation instruction to enter the target application, and the signal acquisition unit transmits the collected action information to the control device of the folding terminal. The control device recognizes the downward action signal and then issues an operation instruction to enter the target application.

[0177] Preferably, the target application is a versatile wallet. That is, when a signal that the lock body moves downward is obtained, the versatile wallet is entered, so that the terminal interface displays the wallpaper of the versatile wallet.

[0178] Specifically, taking a foldable mobile phone as an example, the advantages of the target application being a versatile wallet are explained: when a mobile phone is folded, a locking device 2 is usually required to lock the main frame and the secondary frame together to prevent the secondary frame from tilting upward when folded onto the main frame and affecting the user's use of the mobile phone; the versatile wallet is specifically designed for use when the mobile phone is in a folded state to increase the unique beauty of the mobile phone in the folded state. Therefore, the target application is preferably a versatile wallet, so that when the folded mobile phone operates the locking device 2, the versatile wallet is entered at the same time, and the mobile phone interface displays the wallpaper in the versatile wallet.

[0179] In one embodiment, the method specifically includes: obtaining a rotation signal of the lock body; and identifying the rotation signal as an operation instruction of the current interface.

[0180] Obtain the rotation signal of the lock body, and use the signal acquisition unit in the lock device 2 to obtain the rotation action signal of the lock body (force structure 21); identify the rotation signal as an operation instruction of the current interface, and the signal acquisition unit transmits the collected rotation action information to the control device of the folding terminal. The control device recognizes the rotation action signal and then issues an operation instruction of the current interface.

[0181] By rotating the force-applying structure 21 to operate the current interface of the foldable terminal, different operation instructions can be provided according to different applications currently displayed. Taking a foldable mobile phone as an example, the role of the rotating force-applying structure 21 in different applications is specifically described.

[0182] 1. Rotate the force-applying structure 21 to adjust the volume (corresponding to the volume adjustment instruction)

[0183] When the force-applying structure 21 is rotated to adjust the volume, the volume adjustment key on the foldable mobile phone can be removed, thereby simplifying the structure of the foldable mobile phone.

[0184] Open the mobile phone interface, and icons of various applications will be displayed on the mobile phone interface. At this time, rotating the force-applying structure 21 can adjust the volume (for example, rotating clockwise increases the volume, and rotating counterclockwise decreases the volume), and the volume adjustment icon will also be displayed on the interface when rotating the force-applying structure 21.

[0185] When a music application is opened, the force-applying structure 21 is generally rotated to adjust the volume of the sound in the music application.

[0186] Of course, in other applications, the sound volume can also be adjusted by rotating the force-applying structure 21 .

[0187] 2. Rotate the force-applying structure 21 to realize page turning or picture turning (corresponding to page turning or book turning instructions)

[0188] When entering a reading application, the page can be turned by rotating the force-applying structure 21. For example, when rotating clockwise, the next page is turned, and when rotating counterclockwise, the previous page is turned.

[0189] When the force-applying structure 21 is rotated, the picture can also be turned. For example, by clicking on one of the pictures in the album, the current interface only displays the picture, and then rotating the force-applying structure 21, the picture can be turned. For example, when rotating clockwise, the picture is turned to the next one, and when rotating counterclockwise, the picture is turned to the previous one.

[0190] When the force-applying structure 21 is rotated, pictures can be turned over, and this can also be realized in related shopping applications, such as in Taobao, clicking on one of the pictures makes the current interface only display the picture, and then rotating the force-applying structure 21 to turn over the pictures. In other words, the force-applying structure 21 can be set to rotate to realize browsing pictures.

[0191] 3. Rotating the force-applying structure 21 to achieve zooming in / out of the lens when taking photos (corresponding to the zoom-in / zoom-out instructions of the lens)

[0192] When entering the camera function, the zoom function of the mobile phone is used to zoom the lens in / out by rotating the force-applying structure 21. For example, when rotating clockwise, the lens zooms in, and when rotating counterclockwise, the lens zooms out.

[0194] When entering the application of the relevant video, fast forward / fast rewind is achieved by rotating the force-applying structure 21. For example, fast forward is achieved when rotating clockwise, and fast rewind is achieved when rotating counterclockwise. As for the multiple of fast forward / fast rewind, it can be achieved by rotating the force-applying structure 21 at a certain speed.

[0195] Here, it should be noted that, for video applications, the volume can also be set to adjust by rotating the force-applying structure 21. However, for the interface where the video application is playing a video, the force-applying structure 21 can only be set to adjust the volume or fast forward / fast rewind.

[0196] 5. Rotate the force-applying structure 21 to achieve up and down sliding (corresponding to up and down sliding instructions)

When rotating clockwise, it slides down, and when rotating counterclockwise, it slides up. That is, when the interface displays the list content, the force structure 21 is rotated to slide up and down.

[0198] For example, for applications such as Douyin and Kuaishou, different videos can be played by rotating the force-applying structure 21. When rotating clockwise, the next short video is played, and when rotating counterclockwise, the previous short video is played.

[0199] 6. Rotating the force-applying structure 21 to switch between different applications (corresponding to the application switching instruction)

[0200] For example, after long pressing the image / content, click Copy, and then rotate the force-applying structure 21 to switch to another application set by the system, and paste the content into the editing box of the application.

[0201] 7. Rotate the force-applying structure 21 to implement the input box switching option instruction (corresponding to the input box switching option instruction)
