Description

[0001] This application is a divisional application of the Chinese patent application submitted to the China Patent Office on August 5, 2023, with application number 202310983140.4, and invention name "A rocker mechanism, connecting assembly and electronic device". Technical Field

[0003] Currently, many electronic devices have multiple housing parts. For example, a laptop computer may include a display end housing and a keyboard end housing. Two adjacent housing parts may be mechanically connected by a hinge mechanism, and one housing part (such as the display end housing) may rotate relative to the other housing part (such as the keyboard end housing) around the rotation pivot axis of the hinge mechanism to achieve opening and closing of the electronic device. When the two housing parts need to transmit electrical signals, the electronic components on the two housing parts may be electrically connected by a flexible printed circuit (FPC).

[0004] The flexible circuit board can pass through the gap in the center of the hinge mechanism or bypass the surface of the hinge mechanism to connect the electrical functions of the two housing parts. In the former implementation, the flexible circuit board directly rubs against the hinge mechanism, which has a high risk of damage and poor reliability. In the latter implementation, during the opening and closing process, the flexible circuit board extending from the system side is prone to arching at any position due to the change in length, which may cause severe extrusion and cause the flexible circuit board to break and fail.

[0065] refer to Figure 1 , the electronic device 100 may include a first body assembly 110 , a second body assembly 120 , and a hinge mechanism 130 .

[0066] The first body assembly 110 includes a first housing 111 .

[0067] The first housing 111 is formed with a first accommodation space, and the first accommodation space is used to accommodate the electronic device disposed on one side of the first body assembly 110. The first housing 111 can also play the role of protecting the electronic device and dissipating heat.

[0068] The first shell 111 may be made of metal, such as aluminum-magnesium alloy, titanium alloy, etc. The first shell 111 may also be made of non-metallic material, such as carbon fiber, polycarbonate (PC), engineering plastic, etc.

[0069] The electronic components contained in the first housing 111 include, but are not limited to, a display screen, a camera, an antenna, a speaker, a processor, a memory, a sensor, etc. For the convenience of description, in the embodiment of the present application, the electronic components disposed on one side of the first body assembly 110 are referred to as first electronic components. The first electronic components can also be understood as components disposed on the first housing 111.

[0070] Exemplarily, the first electronic component disposed on one side of the first body assembly 110 includes a display screen 112. The display screen 112 is received in a first accommodation space formed by the first housing 111 and is connected to the first housing 111.

[0071] The display screen 112 is used to display images. The display screen 112 can be a liquid crystal display (LCD) screen, an organic light emitting diode (OLED) display screen, etc., wherein the OLED display screen can be a flexible display screen or a rigid display screen.

[0073] The display screen 112 may be a touch panel capable of implementing touch input, or may be a non-touch panel, which is not limited in the present application.

[0074] The display screen 112 has a light emitting surface capable of displaying images. In the embodiment of the present application, the side surface of the display screen 112 opposite to the light emitting surface is referred to as the back side of the display screen 112. The back side of the display screen 112 is accommodated in the first accommodation space and is not visible to the user.

[0075] In some embodiments, the first body assembly 110 provided with the display screen 112 may also be referred to as a display end or a display portion.

[0076] It should be understood that the first body assembly 110 may also include other components, which will not be described in detail here for the sake of brevity.

[0077] The second body assembly 120 includes a second housing 121 .

[0078] The second housing 121 is formed with a second accommodation space, and the second accommodation space is used to accommodate the electronic device disposed on one side of the second body assembly 120. The second housing 121 can also play the role of protecting the electronic device and dissipating heat.

[0079] The material of the second housing 121 can be a metal material, such as aluminum-magnesium alloy, titanium alloy, etc., or a non-metal material, such as carbon fiber, polycarbonate (PC), engineering plastic, etc. The material of the second housing 121 and the first housing 111 can be the same or different.

[0080] The electronic components contained in the second housing 121 include, but are not limited to, antennas, processors, memories, exhaust fans, keyboards, touchpads, batteries, motherboards, etc. For ease of description, in the embodiment of the present application, the electronic components disposed on one side of the second body assembly 120 are referred to as second electronic components. The second electronic components can also be understood as components disposed on the second housing 121.

[0081] Exemplarily, the second electronic component disposed on one side of the second body assembly 120 includes an input device, such as a keyboard 122, a touch pad 123, etc. The input device is received in the second accommodation space formed by the second housing 121 and connected to the second housing 121 for realizing human-computer interaction.

[0082] The electronic device 100 may also include other input devices, such as a mouse, a handwriting input device, a voice input device, a scanner, a light pen, a joystick, etc., which will not be described in detail here. It should be noted that the camera provided on the electronic device and the display screen 112 with a touch function are also an input device.

[0083] In some embodiments, the second body assembly 120 provided with the keyboard 122 may also be referred to as a keyboard end or a keyboard portion.

[0084] It should be understood that the second body assembly 120 may also include other components, which will not be described in detail here for the sake of brevity.

[0085] The hinge mechanism 130 is hinged between the first body component 110 and the second body component 120. The hinge mechanism 130 includes a rotation pivot axis 1301 (i.e., a hinge axis), and the hinge mechanism 130 can realize the rotation of the first body component 110 relative to the second body component 120 around the rotation pivot axis 1301, or the rotation of the second body component 120 relative to the first body component 110 around the rotation pivot axis 1301, so as to realize the folding (or closing) and opening of the electronic device 100.

[0086] That is, the first body assembly 110 and the second body assembly 120 are attached to the hinge mechanism 130, and the hinge mechanism 130 allows the first body assembly 110 and the second body assembly 120 to rotate relative to each other around their rotation pivot axis 1301. For example, by rotating the first body assembly 110 relative to the second body assembly 120 around the rotation pivot axis 1301 using the hinge mechanism 130, the electronic device 100 can be converted between a folded state and an open state.

[0087] In the embodiment of the present application, an edge of the first shell 111 and an edge of the second shell 121 are respectively attached to the hinge mechanism 130, and the first shell 111 and the second shell 121 can rotate relative to each other around the rotation pivot axis 1301, thereby enabling the first electronic component disposed on the first shell 111 and the second electronic component disposed on the second shell 121 to rotate relative to each other around the rotation pivot axis 1301. In the embodiment of the present application, the motion state of the first shell 111 can be equated with the motion state of the first body assembly 110, and the motion state of the second shell 121 can be equated with the motion state of the second body assembly 120. Since the edges of the first shell 111 and the second shell 121 are hinged by the hinge mechanism 130, the first shell 111 and the second shell 121 can be in a stacked state or in an unfolded state with an angle.

[0088] For example, when the electronic device 100 is folded, the angle between the first body assembly 110 and the second body assembly 120 may approach 0°, and the two surfaces of the first body assembly 110 and the second body assembly 120 that form the angle (e.g., the light emitting surface of the display screen 112 and the keyboard 122) are close to each other. When the electronic device 100 is in the folded state, the display screen 112 and the keyboard 122 may be accommodated in the accommodation space formed by the first shell 111 and the second shell 121.

[0089] For another example, when the electronic device 100 is opened, the angle between the first body assembly 110 and the second body assembly 120 may be close to 90° to 180°, or a larger angle, and the two surfaces (e.g., the light emitting surface of the display screen 112 and the keyboard 122) on the first body assembly 110 and the second body assembly 120 that form the angle are away from each other. When the electronic device 100 is in the opened state, the display screen 112 and the input device (e.g., the keyboard 122 and the touchpad 123) may be exposed for use by the user.

[0090] In some embodiments, when the angle between the first body assembly 110 and the second body assembly 120 is greater than a preset angle, the first body assembly 110 can stay at any position during the rotation of the first body assembly 110 relative to the second body assembly 120 around the rotation pivot axis 1301 .

[0091] When the angle between the first body assembly 110 and the second body assembly 120 is less than or equal to the preset angle, the first body assembly 110 will be in an unbalanced state and can automatically move closer to the second body assembly 120, eventually placing the electronic device 100 in a folded state.

[0092] It should be understood that the angle between the first body assembly 110 and the second body assembly 120 can be understood as the opening and closing angle of the hinge mechanism 130 .

[0093] Of course, in some embodiments, the angle between the first body assembly 110 and the second body assembly 120 can be considered as the angle between the plane where the light emitting surface of the display screen 112 is located and the plane where the striking surface of the keyboard 122 is located.

[0094] In other embodiments, the angle between the first body assembly 110 and the second body assembly 120 may be considered as the angle between the first shell 111 and the second shell 121. Specifically, the angle may be the angle between the plane where the first shell 111 is located and the plane where the second shell 121 is located. In the embodiment of the present application, the plane where the first shell 111 is located may be considered as the plane where the largest area portion of the first shell 111 is located (may also be referred to as the main plane of the first shell 111), and similarly, the plane where the second shell 121 is located may be considered as the plane where the largest area portion of the second shell 121 is located (may also be referred to as the main plane of the second shell 121).

[0095] It should be noted that the electronic components disposed on one side of the first body assembly 110 and the electronic components disposed on one side of the second body assembly 120 may be completely identical, partially identical, or completely identical, and the above description is merely an exemplary description.

[0096] For example, the first body assembly 110 may include a first display screen, and the second body assembly 120 may include a second display screen. When the electronic device is folded, the light emitting surface of the first display screen faces the light emitting surface of the second display screen. In this way, the electronic device 100 is a dual-screen device.

[0097] It should be understood that Figure 1 Only some components of the electronic device 100 are schematically shown, and the shapes, sizes and structures of these components are not limited to the following. Figure 1 In some other embodiments, the electronic device 100 may include more or fewer components than those shown in the figure, which is not limited in the embodiments of the present application. In other embodiments, the types of the electronic device 100 are different, and the components included in the electronic device 100 are different. The electronic device structure provided in the embodiments of the present application is only for illustrative purposes.

[0098] In the embodiment of the present application, in addition to the mechanical connection between the first body assembly 110 and the second body assembly 120 through the hinge mechanism 130, in some embodiments, the first body assembly 110 and the second body assembly 120 also need to be electrically connected to transmit signals between the first body assembly 110 and the second body assembly 120.

[0099] At present, there are two main ways to achieve electrical connection. One is to connect electrical functions through flexible cables, and the other is to connect electrical functions through flexible printed circuits (FPC). For easy understanding, the following takes the LCD driver board used to control the driving of the LCD display as an example to briefly introduce its electrical connection method.

[0100] In one case, the LCD driver board is located on one side of the first body assembly 110 (i.e., the display end), and the LCD driver board and the display screen are located on the same shell part. The LCD driver board can be electrically connected to electronic components such as a microcontroller unit (MCU) on one side of the second body assembly 120 through a flexible cable.

[0101] Since the LCD driver board is arranged on the screen side (eg Figure 1 The LCD driver board is located below the display screen 112 on the first body assembly 110 in the middle, so the LCD driver board occupies the displayable area of ​​the display screen, making it difficult to further increase the proportion of the displayable area on the screen side, affecting the display experience. In addition, the flexible cable is connected to the LCD driver board through a connector, and the flexible cable and the connector occupy the thickness space on the screen side, making it difficult to further reduce the thickness of the body on the screen side, affecting the appearance experience.

[0102] In order to increase the screen-to-body ratio of the display screen and achieve thinness and lightness, in another case, the LCD driver board can be set on one side of the second body assembly 120 (i.e., the keyboard end), and the LCD driver board and the display screen are located on different shell parts. The LCD driver board can be electrically connected to the electronic components on one side of the first body assembly 110, such as the LCD display screen, through a flexible circuit board.

[0103] For example, the first body component 110 and the second body component 120 are mechanically connected through a bracelet-like hinge mechanism 130, and the flexible circuit board passes through the gap in the center of the hinge mechanism 130 to connect the electrical functions on the first body component 110 side and the second body component 120 side, wherein the gap channel of the hinge mechanism 130 can constrain the movement of the flexible circuit board 101 and protect the flexible circuit board. Although the gap channel of the hinge mechanism 130 can constrain the movement of the flexible circuit board FPC in this way, it needs to be used in conjunction with the bracelet-like hinge mechanism, which has a complex structure and high cost. The flexible circuit board directly rubs against the metal hinge mechanism, and the risk of damage is high. In addition, when the cable passes through the hinge gap channel, the hinge structure is large in size, which is not conducive to the thinness of electronic equipment.

[0104] For another example, the second body assembly 120 includes a folding bracket, and the LCD driving board is fixed on the folding bracket. One end of the flexible circuit board is connected to the LCD driving board, and the other end is extended along the circumference of the folding bracket for one circle, bypasses the hinge mechanism 130, and is connected to the electronic components in the first body assembly 110, wherein the initial extension direction of the other end of the flexible circuit board is the opening direction of the first body assembly 110. When the first body assembly 110 rotates relative to the second body assembly 120 around the rotation pivot axis, the flexible circuit board FPC located in the accommodation space of the second body assembly 120 can float freely. In this way, since the flexible circuit board located in the cavity of the second body assembly 120 is in a free floating state, the flexible circuit board is prevented from being tightened, and the force on the flexible circuit board can be reduced. However, when the electronic device is closed, the flexible circuit board located at the hinge mechanism 130 will be arched, which is easy to cause severe extrusion of the flexible circuit board, thereby causing the flexible circuit board to break.

[0105] Therefore, the embodiments of the present application provide a rocker mechanism, a connection assembly, and an electronic device, which can constrain the movement of a flexible circuit board FPC, thereby improving the reliability of the electrical connection of the flexible circuit board FPC.

The open state here refers to the state when the electronic device has the largest engagement angle.

[0107] refer to Figure 2-Figure 5 The electronic device 200 includes a first body component 110 , a second body component 120 , a hinge mechanism 130 and a connection component 140 .

[0108] The first body assembly 110 includes a first housing 111 and a first electronic component 1101. The first housing 111 forms a first accommodation space, and the first electronic component 1101 is accommodated in the first accommodation space.

[0109] The material of the first shell 111 can be metal, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, austenitic stainless steel, etc.; it can also be non-metallic material, such as carbon fiber, polycarbonate (PC), engineering plastics, glass, ceramics, wood, leather, sapphire, composite materials, etc.

[0110] The first electronic component 1101 is any component that needs to be electrically connected to the electronic components in the second body assembly 120. Exemplarily, the first electronic component 1101 may be a display screen or a display screen adapter board.

[0111] The second body assembly 120 includes a second housing 121, a second electronic component 1201 and an exhaust hole 1202. The second housing 121 is formed with a second accommodation space, and the second electronic component 1201 is accommodated in the second accommodation space. The exhaust hole 1202 is provided at one end where the second housing 121 is connected to the first housing 111, and is used to exhaust the gas in the second accommodation space to achieve heat dissipation.

[0112] The material of the second shell 121 can be metal, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, austenitic stainless steel, etc.; it can also be non-metallic material, such as carbon fiber, polycarbonate (PC), engineering plastics, glass, ceramics, wood, leather, sapphire, composite materials, etc.

[0113] The material of the second housing 121 may be the same as or different from the material of the first housing 111 .

[0114] The second electronic component 1201 is any one of the components electrically connected to the first electronic component 1101. Exemplarily, the second electronic component 1201 may be a display screen driving board.

[0115] The hinge mechanism 130 is hinged between the first body assembly 110 and the second body assembly 120, and the first body assembly 110 can rotate relative to the second body assembly 120 around a rotation pivot axis 1301 (i.e., a hinge axis) through the hinge mechanism 130. More specifically, the hinge mechanism 130 is hinged between the first housing 111 and the second housing 121, and the first housing 111 and the second housing 121 can rotate relative to each other around the rotation pivot axis 1301 of the hinge mechanism 130.

[0116] The connecting assembly 140 includes a flexible circuit board 141 and a rocker mechanism 142 .

[0117] The flexible circuit board 141 includes a first end 1411, a second end 1412, and a middle section 1413 located between the first end 1411 and the second end 1412. The second end 1412 is a fixed end, and the first end 1411 is movable relative to the second end 1412. In the embodiment of the present application, the first end 1411 is connected to the first electronic component 1101 located on the first housing 111, and the second end 1412 bypasses the hinge mechanism 130 and is connected to the second electronic component 1201 located on the second housing 121.

[0118] It should be noted that the fixed mentioned here can be understood as relatively fixed. For example, the second end 1412 is a fixed end, which can be understood as the second end 1412 being fixed relative to the second housing 121 (or the second electronic component 1201 ).

[0119] In the embodiment of the present application, the hinge mechanism 130 may have a curved surface. When the first housing 111 rotates relative to the second housing, a portion of the flexible circuit board 141 close to the first end 1411 may be disposed around the curved surface.

[0120] like Figure 4 and Figure 5 As shown, an opening ( Figure 6 The middle section 1413 of the flexible circuit board 141 extends from the second accommodation space through the opening, bypasses the curved surface of the hinge mechanism 130, and enters the first accommodation space of the first housing 111. When the first housing 111 and the second housing 121 rotate relative to each other around the rotation pivot axis 1301 of the hinge mechanism 130, the middle section 1413 of the flexible circuit board 141 extends from the second accommodation space through the opening or enters the second accommodation space through the opening.

[0121] It should be noted that, since the flexible circuit board 141 and the structural member at the opening slide and rub against each other during the rotation of the first housing 111 relative to the second housing 121, a lubricating component may be provided in the contact area between the opening and the flexible circuit board 141 in the embodiment of the present application, and the friction force on the flexible circuit board 141 is reduced by the lubricating component, thereby preventing the wear of the flexible circuit board 141. By way of example, the lubricating component may be a Teflon tape.

[0122] like Figure 5 As shown, the opening and the rocker mechanism 142 are arranged in the middle area of ​​one end where the second shell 121 is connected to the first shell 111, and the length of the opening and the rocker mechanism 142 along the rotation pivot axis 1301 corresponds to the width of the flexible circuit board 141 (that is, the size of the flexible circuit board 141 in the direction of the rotation pivot axis 1301).

[0123] The rocker mechanism 142 is used to pull the middle section 1413 of the flexible circuit board 141 to guide and tension the flexible circuit board 141 when the first shell 111 rotates relative to the second shell 121 around the rotation pivot axis 1301 (i.e., when the first end 1411 of the flexible circuit board moves relative to the second end 1412 of the flexible circuit board).

[0124] In the embodiment of the present application, the rocker mechanism 142 applies a pulling force to the flexible circuit board 141. In some embodiments, the pulling force forms an obtuse angle or a straight angle with the movement direction of the flexible circuit board 141 when the first body assembly 110 is opened relative to the second body assembly 120, so that the pulling force has a force component in the movement direction of the flexible circuit board, or the direction of the pulling force is opposite to the movement direction of the flexible circuit board when the first body assembly 110 is opened relative to the second body assembly 120, thereby achieving a guiding and tensioning effect on the flexible circuit board 141.

[0125] In other words, the first end 1411 of the flexible circuit board 141 is connected to the first electronic component 1101 on the first body assembly 110, and the first end 1411 is subjected to the force of the first body assembly 110, the second end 1412 of the flexible circuit board 141 is connected to the second electronic component 1201 on the second body assembly 120, and the second end 1412 is subjected to the force of the second body assembly 120, and the middle section 1413 of the flexible circuit board 141 is pulled by the swing mechanism 142, and the middle section 1413 is subjected to the pulling force of the swing mechanism 142. The flexible circuit board 141 can maintain balance under the combined action of the above forces.

[0126] Optionally, the direction of the pulling force applied by the rocker mechanism 142 to the flexible circuit board 141 may be opposite to the direction of the force applied by the first body assembly 110 to the first end 1411, or the pulling force has a force component in the movement direction of the flexible circuit board, and the force component is opposite to the direction of the force applied by the first body assembly 110 to the first end 1411.

[0127] It should be noted that the force applied by the first body assembly 110 to the first end 1411 mentioned here can be understood as an equivalent force applied to the first end 1411, or as a force applied to the portion of the flexible circuit board outside the first body assembly 110 near the first body assembly. The movement direction of the flexible circuit board mentioned here can be understood as the movement direction of the flexible circuit board between the first end 1411 and the rocker mechanism 142.

[0128] Figure 6 A schematic diagram of the structure of a rocker mechanism provided in an embodiment of the present application, wherein the rocker element is in a first position; Figure 7 A schematic diagram of the structure of a rocker mechanism provided in an embodiment of the present application, wherein the rocker element is in a second position; Figure 8 A schematic diagram of an exploded view of a rocker mechanism provided in an embodiment of the present application; wherein the first position corresponds to the position of the rocker element when the electronic device is in a closed state, also referred to as the initial position; the second position is the position of the rocker element when the electronic device is at a maximum opening angle, also referred to as the end position.

[0129] like Figure 6-Figure 8 As shown, in the embodiment of the present application, the rocker mechanism 142 may include a base 1421 , a rocker element 1422 and an elastic element 1423 .

[0130] Exemplarily, the base 1421 and the rocker element 1422 may be made of plastic material, and the elastic element 1423 may be made of metal material such as copper or nylon.

[0131] The base 1421 is disposed on a side of the second housing 121 close to the first housing 111. The specific location can be referred to Figure 5 Exemplary positions are shown. Exemplarily, a mounting hole 1424 is provided on the base 1421 , and the base 1421 can be fixed to the second housing 121 through the mounting hole 1424 and a fastener.

[0132] The rocker element 1422 and the elastic element 1423 are mounted on the base 1421. The rocker element 1422 can rotate between an initial position and an end position relative to the base. The elastic element 1423 is used to apply elastic force to the rocker element 1422 to return the rocker element 1422 to the initial position.

[0133] Here, the swing rod element 1422 can rotate between the initial position and the final position relative to the base 1421, which means that the swing rod element 1422 can rotate relative to the base 1421 from the initial position ( Figure 3 and Figure 6 shown position) to the end position ( Figure 2 and Figure 7 The target position is any position between the initial position and the end position.

[0134] Furthermore, in the embodiment of the present application, a first stopper 1425 and a second stopper 1426 are also provided on the base 1421. When the swing element 1422 is located at the initial position, the swing element 1422 abuts against the first stopper 1425, and the swing element 1422 is kept at the initial position by the stopper of the first stopper 1425 and the elastic force of the elastic element. When the swing element 1422 is located at the final position, the swing element 1422 abuts against the second stopper 1426, and the swing element 1422 is kept at the final position by the stopper of the second stopper 1426 and the pulling of the flexible circuit board 141 (from the force applied to the first end 1411 by the first body assembly 110). When the swing element 1422 is located at any position between the initial position and the final position, the balance can be achieved by the pulling of the elastic element 1422 and the flexible circuit board 141, and the swing element 1422 is kept at the final position.

[0135] In summary, in the embodiment of the present application, the rocker mechanism 142 is in the initial position ( Figure 6 shown) and the end position ( Figure 7 A stopper is added to ensure its stability during movement and to limit the movement range of the rocker element 1422 between the initial position and the end position.

[0136] It should be understood that the first stopper 1425 and the second stopper 1426 can be in various suitable shapes. For example, the first stopper 1425 and the second stopper 1426 are in a suitable plate or block shape. The first stopper 1425 is relatively small in size, and a first stopper is provided at each end of the base 1421. The second stopper 1426 is relatively large in size, for example, equivalent to the width of the flexible circuit board 141. Of course, the shapes and sizes of the first stopper 1425 and the second stopper 1426 are not limited to Figure 6-Figure 8 As shown, as long as the stopping effect can be achieved.

[0137] It should also be understood that the base 141 may be an integrally formed structure or a detachable structure.

[0138] For example, in the embodiment of the present application, the rocker element 1422 includes a rotating shaft 1427 and a rotating portion 1428 connected to the rotating shaft 1427. A rotating shaft hole is provided on the base 1421, and the rocker element 1422 can be installed on the base 1421 by inserting both ends of the rotating shaft 1427 into the corresponding rotating shaft holes. The rocker element 1422 or the rotating portion 1428 can rotate around the axis of the rotating shaft 1427 relative to the base 1421 between an initial position and an end position.

[0139] By way of example, in the embodiment of the present application, the rotating portion 1428 adopts a plate-like structure, and part of the middle section 1413 of the flexible circuit board 141 is fixed on a side surface of the rotating portion 1428, for example, fixed on a surface of the rotating portion 1428 on a side close to the second electronic component 1201. In this way, the rotation of the swing element 1422 or the rotating portion 1428 will plan the movement path of the flexible circuit board 141, making it less likely to bend and squeezed, thereby avoiding fracture failure caused by the bending and squeezing. By way of example, in the embodiment of the present application, the rotating shaft 1427 and the rotating shaft portion 1428 are integrally formed, that is, the swing element 1422 is an integrally formed structure.

[0140] Exemplarily, in the embodiment of the present application, the elastic element 1423 can be a torsion spring, for example, a coil structure torsion spring, the coil of which is sleeved on the rotating shaft 1427 of the rocker element 1422, the fixed end is installed on the base 1421, and the free end is against the rotating part 1428 of the rocker element 1422. The elastic element 1423 is configured to continuously apply an elastic force to the rocker element 1422 during the movement of the rocker element 1422, and the force prevents the rocker element 1422 from rotating from the initial position to the terminal position. That is, the elastic force makes the rocker element 1422 have a tendency to return to the initial position. The initial position is the position where the angle between the rocker element 1422 and the base 1421 is the largest (for example Figure 3 and Figure 6 The end position is the position where the angle between the rocker element 1422 and the base 1421 is the smallest (e.g. Figure 2 and Figure 7 The position shown in the figure) corresponds to the position of the rocker element 1422 when the electronic device 200 is opened and closed at the maximum angle.

[0141] Here, the angle between the rocker element 1422 and the base 1421 refers to the angle between the plane where the largest area portion of the rocker element 1422 is located and the plane where the mounting surface of the base 1421 is located. The mounting surface of the base 1421 refers to the plane where the mounting hole 1424 is located.

[0142] The maximum and minimum angles between the rocker element 1422 and the base 1421 (or the horizontal plane) depend on the angle between the first stopper 1425 and the second stopper 1426. The angle between the first stopper 1425 and the second stopper 1426 is determined according to the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 200 (i.e., the angle between the first housing 111 and the second housing 121). For example, when the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 200 is about 135 degrees at most, the angle between the first stopper 1425 and the second stopper 1426 is about 90 degrees. When the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 200 is about 180 degrees at most (the first housing 111 of the electronic device 200 is flattened relative to the second housing 121), the angle between the first stopper 1425 and the second stopper 1426 is about 120 degrees.

[0143] Here, the included angle between the first stopper 1425 and the second stopper 1426 refers to the angle between the surfaces of the first stopper 1425 and the second stopper 1426 that are opposite to each other.

[0144] For example, in the embodiment of the present application, the rocker element 1422 or the rotating portion 1428 can rotate within a range of 0-120 degrees.

[0145] Continue to refer Figure 2 and Figure 5 In the embodiment of the present application, the two ends of the swing element 1422, that is, the swing mechanism 142, are placed along the direction of the rotation pivot axis 1301. A partial area of ​​the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing element 1422, for example, fixed on a side surface of the rotating part 1428. Exemplarily, it can be fixed by a suitable adhesive.

[0146] Here, the rotation axis 1427 of the rocker element 1422 may include a center line (or axis) that is parallel to the rotation pivot axis 1301 .

[0147] In some embodiments, the swing element 1422 is disposed within the stacking range of the flexible circuit board 141. The stacking range of the flexible circuit board involved here can be understood as the movement area where the part of the flexible circuit board with the largest shape change is located during the relative rotation of the first shell 111 and the second shell 121.

[0148] When the first body assembly 110 rotates relative to the second body assembly 120 around the rotation pivot axis 1301, the first body assembly 110 drives the flexible circuit board 141 to move in the rotation direction of the first body assembly 110. Since a part of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing element 1422, under the combined action of the elastic element 1423 and the first body assembly 110, the flexible circuit board 141 moves together with the swing element 1422. In this process, the elastic element 1423 applies a force to the swing element 1422 to prevent it from moving, so that the flexible circuit board 141 is slightly tightened during the movement to keep it flat. In addition, the rotation of the swing element 1422 limits the movement path of the flexible circuit board 141, making it less likely to be bulged and squeezed, thereby preventing the flexible circuit board 141 from breaking and failing due to bulging and squeezing.

[0149] For example, when the electronic device is opened, the first body assembly 110 moves in an opening direction (for example, according to the direction of the opening direction) relative to the second body assembly 120. Figure 2 The flexible circuit board 141, driven by the first body assembly 110, also moves in this direction (i.e., extends out of the second cavity), for example, wrapped around the curved surface of the hinge mechanism 130. At the same time, the swing element 1422 rotates from the initial position (for example, according to the clockwise direction in the figure) under the action of the flexible circuit board 141. Figure 3 In the embodiment of the present invention, the first body assembly 110 and the rocker element 1422 are used to rotate the flexible circuit board 141. The ...

[0150] For example, when the electronic device is closed, the first body assembly 110 moves in a closing direction (for example, according to Figure 3 The first body assembly 110 gradually reduces the force exerted on the flexible circuit board 141, and the swing element 1422 also moves to the initial position direction (for example, according to the counterclockwise direction in FIG. 1 ) under the action of the elastic element 1423. Figure 3The flexible circuit board 141 is also driven to move in the same direction. At this time, since part of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing element 1422, and the swing element 1422 has a pulling force on the flexible circuit board 141, it is ensured that the flexible circuit board 141 is slightly tightened during the movement to maintain flatness during the movement. In this way, under the action of the swing element 1422, the part of the flexible circuit board 141 located outside the second accommodating cavity is close to the curved surface of the hinge mechanism 130 without being arched or squeezed. As for the part of the flexible circuit board that enters the second accommodating cavity, since the rotation of the swing element 1422 will limit or plan the movement path of the flexible circuit board 141, it is also not easy to be arched or squeezed, so that the flexible circuit board 141 is prevented from breaking and failing due to arching and squeezing.

[0151] Therefore, in the embodiment of the present application, during the relative rotation of the first body assembly 110 and the second body assembly 120, the movement form and path of the flexible circuit board 141 are constrained under the action of the rocker mechanism 142, so that the flexible circuit board can achieve controlled reciprocating movement. The flexible circuit board 141 can remain flat during the movement and is subjected to a relatively uniform force, so that the service life of the flexible circuit board 141 can be extended, and the long-term reliability of the flexible circuit board 141 is improved.

[0153] refer to Figure 9-13 The electronic device 300 includes a first body component 110, a second body component 120, a hinge mechanism 130 and a connection component 140. The connection component 140 includes a flexible circuit board 141 and a swing rod mechanism 242.

[0154] The electronic device 300 has a substantially similar structure to the electronic device 200 , except that the structure of the swing mechanism 242 of the electronic device 300 is different from that of the swing mechanism 142 of the electronic device 200 .

[0155] like Figure 11-13 As shown, in the embodiment of the present application, the rocker mechanism 242 may include a base 2421 , a rocker element 2422 and an elastic element 2423 .

[0156] The base 2421 is disposed on a side of the second housing 121 close to the first housing 111. The specific location can be found in Figure 5 Exemplary positions are shown. For example, a mounting hole 2424 is provided on the base 2421 , and the base 2421 can be fixed to the second housing 121 through the mounting hole 2424 and a fastener.

[0157] The rocker element 2422 and the elastic element 2423 are mounted on the base 2421. The rocker element 222 can rotate between an initial position and an end position relative to the base. The elastic element 2423 is used to apply elastic force to the rocker element 2422 to return the rocker element 2422 to the initial position.

[0158] Here, the swing rod element 2422 can rotate between the initial position and the final position relative to the base 2421, which means that the swing rod element 2422 can rotate between the initial position and the final position relative to the base 2421. Fig.11 shown position) to the end position ( Fig.12 The target position is any position between the initial position and the end position.

[0159] Furthermore, in the embodiment of the present application, a first stopper 2425 and a second stopper 2426 are also provided on the base 2421. When the swing element 2422 is located at the initial position, the swing element 2422 abuts against the first stopper 2425, and the swing element 2422 is kept at the initial position by the stopper of the first stopper 2425 and the elastic force of the elastic element. When the swing element 2422 is located at the final position, the swing element 2422 abuts against the second stopper 2426, and the swing element 2422 is kept at the final position by the stopper of the second stopper 2426 and the pulling of the flexible circuit board 141 (from the force applied to the first end 1411 by the first fuselage assembly 110). When the swing element 2422 is located at any position between the initial position and the final position, the balance can be achieved by the pulling of the elastic element 2423 and the flexible circuit board 141, and the swing element 2422 is kept at the final position.

[0160] In summary, in the embodiment of the present application, the rocker mechanism 242 is in the initial position ( Fig.11 shown) and the end position ( Fig.12 A stopper is added to ensure its stability during movement and to limit the movement range of the rocker element 2422 between the initial position and the end position.

[0161] It should be understood that the first stopper 2425 and the second stopper 2426 can be in various suitable shapes and sizes. For example, the first stopper 2425 and the second stopper 2426 are in a suitable plate or block shape. The first stopper 2425 is a relatively small inclined plate, and a first stopper 2425 is provided at each end of the base 2421. The second stopper 2426 is a relatively large flat plate, for example, with a width equivalent to that of the flexible circuit board 141. Of course, the shapes and sizes of the first stopper 2425 and the second stopper 2426 are not limited to Figure 11-13 As shown, as long as the stopping effect can be achieved. For example, the first stopper 2425 can also be Fig.14 The flat plate structure shown.

[0162] It should also be understood that the base 241 may be an integrally formed structure or a detachable structure.

[0163] For example, in the embodiment of the present application, the rocker element 2422 includes a rotating shaft 2427 and a rotating portion 2428 connected to the rotating shaft 2427. A rotating shaft hole is provided on the base 2421, and the rocker element 2422 can be installed on the base 2421 by inserting the rotating shaft 2427 into the corresponding rotating shaft hole. The rocker element 2422 or the rotating portion 2428 can rotate around the axis of the rotating shaft 2427 relative to the base 2421 between an initial position and an end position.

[0164] For example, in the embodiment of the present application, the rotating shaft 2427 and the rotating shaft portion 1428 are formed separately, that is, the rotating shaft 2427 and the rotating shaft portion 2428 of the rocker element 2422 are assembled together, not integrally formed.

[0165] In the embodiment of the present application, a through hole is formed in the rotating part 2428, and the size of the through hole matches the size of the rotating shaft 2427. The rotating shaft 2427 can be connected to the rotating part 2428 through the through hole, which can be a rotating connection or a fixed connection. A rotating shaft hole is provided on the base 2421, and the rotating shaft 2427 and the swing rod element 2422 can be installed on the base 2421 by inserting the two ends of the rotating shaft 2427 into the corresponding rotating shaft holes. The swing rod element 2422 can rotate around the rotating shaft 2427 or the axis of the rotating shaft relative to the base 2421 in the initial position ( Fig.11 shown) and the end position ( Fig.12positions shown).

[0166] For example, in the embodiment of the present application, the rotating portion 2428 adopts a plate-like structure, and part of the middle section 1413 of the flexible circuit board 141 is fixed on a side surface of the rotating portion 2428, for example, fixed on a side surface of the rotating portion 2428 close to the second electronic component 1201. In this way, the rotation of the swing element 2422 or the rotating portion 2428 will plan the movement path of the flexible circuit board 141, so that it is not easy to bend and squeezed to cause fracture failure.

[0167] Exemplarily, in the embodiment of the present application, the elastic element 2423 can be a torsion spring, for example, a coil structure torsion spring, the coil of which is sleeved on the rotating shaft 2427 of the rocker element 2422, the fixed end is installed on the base 2421, and the free end is against the rotating part 2428 of the rocker element 2422. The elastic element 2423 is configured to continuously apply an elastic force to the rocker element 2422 during the movement of the rocker element 2422, and the force prevents the rocker element 2422 from rotating from the initial position to the terminal position. That is, the elastic force causes the rocker element 2422 to have a tendency to return to the initial position. The initial position is the position where the angle between the rocker element 2422 and the base 2421 is the largest (for example Fig.10 and Fig.11 The end position is the position where the angle between the rocker element 1422 and the base 2421 is the smallest (e.g. Fig. 9 and Fig.12 The position shown in the figure) corresponds to the position of the rocker element 2422 when the electronic device 300 is opened and closed at the maximum angle.

[0168] The maximum and minimum angles between the rocker element 2422 and the base 2421 (or the horizontal plane) depend on the angle between the first stopper 2425 and the second stopper 2426. The angle between the first stopper 2425 and the second stopper 2426 is determined according to the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 300 (i.e., the angle between the first housing 111 and the second housing 121). For example, when the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 300 is about 135 degrees at most, the angle between the first stopper 2425 and the second stopper 2426 is about 90 degrees. When the opening and closing angle of the hinge mechanism 130 or the opening and closing angle of the electronic device 300 is about 180 degrees at most (the first housing 111 of the electronic device 300 is flattened relative to the second housing 121), the angle between the first stopper 2425 and the second stopper 2426 is about 120 degrees.

[0169] Here, the included angle between the first stopper 2425 and the second stopper 2426 refers to the angle between the surfaces of the first stopper 2425 and the second stopper 2426 that are opposite to each other.

[0170] For example, in the embodiment of the present application, the rocker element 2422 or the rotating portion 2428 can rotate within a range of 0-120 degrees.

[0171] like Fig.15 As shown, it shows a schematic diagram of the corresponding states of the connecting component 140 in the open state and the closed state of the electronic device when the opening and closing angle of the electronic device 300 is 180 degrees or close to 180 degrees.

[0172] like Fig.16 As shown, it shows a schematic diagram of the corresponding states of the connecting component 140 in the open state and the closed state of the electronic device when the opening and closing angle of the electronic device 300 is 135 degrees or close to 135 degrees.

[0173] from Fig.15 and Fig.16 It can be seen that the larger the maximum angle between the rocker element 2422 and the base 2421 (or the horizontal plane), the larger the opening and closing angle of the electronic device 300.

[0174] In the embodiment of the present application, the two ends of the rocker element 2422, that is, the rocker mechanism 242, are placed along the direction of the rotation pivot axis 1301. A partial area of ​​the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the rocker element 2422, for example, fixed on a side surface of the rotating portion 2428. Exemplarily, it can be fixed by a suitable adhesive.

[0175] Here, the rotation axis 2427 of the rocker element 2422 may include a center line (or axis) that is parallel to the rotation pivot axis 1301 .

[0176] In some embodiments, the swing element 2422 is disposed within the stacking range of the flexible circuit board 141. The stacking range of the flexible circuit board involved here can be understood as the movement area where the part of the flexible circuit board with the largest shape change is located during the relative rotation of the first shell 111 and the second shell 121.

[0177] When the first body assembly 110 rotates relative to the second body assembly 120 around the rotation pivot axis 1301, the first body assembly 110 drives the flexible circuit board 141 to move in the rotation direction of the first body assembly 110. Since a part of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing element 2422, under the combined action of the elastic element 2423 and the first body assembly 110, the flexible circuit board 141 moves together with the swing element 2422. In this process, the elastic element 2423 applies a force to the swing element 2422 to prevent it from moving, so that the flexible circuit board 241 is slightly tightened during the movement to keep it flat. In addition, the rotation of the swing element 2422 limits the movement path of the flexible circuit board 141, making it less likely to be arched and squeezed, thereby preventing the flexible circuit board 141 from breaking and failing due to arching and squeezing.

[0178] For example, when the electronic device is opened, the first body assembly 110 moves in an opening direction (for example, according to the direction of the opening direction) relative to the second body assembly 120. Fig. 9 The flexible circuit board 141, driven by the first body assembly 110, also moves in this direction (i.e., extends out of the second accommodating cavity) and is arranged around the curved surface of the hinge mechanism 130. The swing rod element 2422 rotates (for example, according to the clockwise direction) under the action of the flexible circuit board 141. Fig. 9 In the counterclockwise direction in the figure, the elastic force of the elastic element 2423 makes the swing element 2422 have a tendency to rotate in the clockwise direction, so the swing element 2422 forms a pulling force on the flexible circuit board 141, so that the flexible circuit board 141 is slightly tightened during the movement under the action of the first fuselage component 110 and the swing element 2422, ensuring the flatness of the flexible circuit board 141 during the movement. At the same time, since part of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing element 2422, the rotation of the swing element 2422 will limit or plan the movement path of the flexible circuit board 141, making it less likely to be arched and squeezed, thereby preventing the flexible circuit board 141 from breaking and failing due to arching and squeezing.

[0179] For example, when the electronic device is closed, the first body assembly 110 moves in a closing direction (for example, according to Fig.10 The first body assembly 110 gradually reduces the force exerted on the flexible circuit board 141, and the swing element 2422 moves toward the initial position (for example, according to the counterclockwise direction) under the action of the elastic element 2423. Fig.10The flexible circuit board 141 moves in the clockwise direction (in the middle of the second accommodating cavity), and at the same time drives the flexible circuit board 141 to move in this direction. At this time, since part of the middle section 2413 of the flexible circuit board 141 is fixed on the surface of the swing element 2422, and the swing element 2422 has a pulling force on the flexible circuit board 141, it is ensured that the flexible circuit board 141 is slightly tightened during the movement to maintain flatness during the movement. In this way, under the action of the swing element 2422, the part of the flexible circuit board 141 located outside the second accommodating cavity is close to the curved surface of the hinge mechanism 130 without being arched or squeezed. The flexible circuit board 141 that enters the second accommodating cavity is also not prone to arching and squeezing because the rotation of the swing element 2422 will limit or plan the movement path of the flexible circuit board 141, thereby preventing the flexible circuit board 141 from breaking and failing due to arching and squeezing.

[0180] Therefore, in the embodiment of the present application, during the relative rotation of the first body assembly 110 and the second body assembly 120, the movement form and path of the flexible circuit board 141 will be constrained under the action of the rocker mechanism 242, so that the reciprocating controlled movement of the flexible circuit board can be achieved. The flexible circuit board 141 can remain flat during the movement and the force is relatively uniform, so the service life of the flexible circuit board 141 can be extended, and the long-term reliability of the flexible circuit board 141 is improved.
