Description

Swing rod mechanism, connecting assembly and electronic equipment

Technical Field

The application relates to the technical field of electronic equipment, in particular to a swing rod mechanism, a connecting assembly and electronic equipment.

Background

Many electronic devices currently have multiple housing portions, such as notebook computers that may include a display end housing and a keyboard end housing, with adjacent housing portions being mechanically coupled by a hinge mechanism, wherein one housing portion (e.g., the display end housing) is rotatable relative to the other housing portion (e.g., the keyboard end housing) about a pivot axis of rotation of the hinge mechanism to effect opening and closing of the electronic device. When the two housing parts require electrical signal transmission, the electronic components on the two housing parts may be electrically connected by a flexible circuit board (flexible printed circuit, FPC).

The flexible circuit board may pass through a slot in the center of the hinge mechanism or bypass the surface of the hinge mechanism to connect the electrical functions of the two housing portions. In the former implementation, the flexible circuit board directly rubs with the hinge mechanism, so that the risk of breakage is high, and the reliability is poor. In the latter implementation, during the opening and closing process, the flexible circuit board extending from the system side is easy to arch at any position due to the length change, and serious extrusion may be formed, so that the flexible circuit board breaks and fails.

Accordingly, it is desirable to provide an electrical connection method that can improve the reliability of the electrical connection of the flexible circuit board.

Referring to fig. 1, an electronic device 100 may include a first body assembly 110, a second body assembly 120, and a hinge mechanism 130.

The first body assembly 110 includes a first housing 111.

The first case 111 is formed with a first receiving space for receiving an electronic device provided at one side of the first body assembly 110. The first housing 111 may also function to protect electronic devices, dissipate heat, etc.

The display 112 has a light emitting surface capable of displaying a picture, and in the embodiment of the present application, a surface of the display 112 opposite to the light emitting surface is referred to as a back surface of the display 112. The back surface of the display 112 is accommodated in the first accommodation space and is not seen by the user.

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

It should be appreciated that the first body assembly 110 may also include other components, which are not described in detail herein for brevity.

The second body assembly 120 includes a second housing 121.

The second housing 121 is formed with a second receiving space for receiving an electronic device provided at one side of the second body assembly 120. The second housing 121 may also function to protect electronic devices, dissipate heat, etc.

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

The electronic devices housed in the second housing 121 include, but are not limited to, an antenna, a processor, a memory, an exhaust fan, a keyboard, a touch panel, a battery, a main board, and the like. For convenience of description, in the embodiment of the present application, the electronic device disposed at one side of the second body assembly 120 is referred to as a second electronic component. The second electronic component may also be understood as a component provided on the second housing 121.

Illustratively, 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, and the like. The input device is accommodated in a second accommodating space formed by the second housing 121 and is connected with the second housing 121 for realizing man-machine interaction.

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

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

It should be appreciated that the second body assembly 120 may also include other components, which are not described in detail herein for brevity.

The hinge mechanism 130 is hinged between the first body assembly 110 and the second body assembly 120. The hinge mechanism 130 includes a pivot axis 1301 (i.e., hinge axis), and the hinge mechanism 130 may enable the first body assembly 110 to rotate about the pivot axis 1301 relative to the second body assembly 120, or the second body assembly 120 to rotate about the pivot axis 1301 relative to the first body assembly 110, to enable folding (or closing) and opening of the electronic device 100.

That is, the first and second body assemblies 110, 120 are attached to the hinge mechanism 130, the hinge mechanism 130 allowing the first and second body assemblies 110, 120 to rotate relative to one another about their pivot axes of rotation 1301. For example, the electronic device 100 may be transitioned between the collapsed state and the open state by rotating the first body assembly 110 about the pivot axis 1301 relative to the second body assembly 120 using the hinge mechanism 130.

In the embodiment of the present application, an edge of the first housing 111 and an edge of the second housing 121 are respectively attached to the hinge mechanism 130, and the first housing 111 and the second housing 121 are rotatable relative to each other about the pivot axis 1301, so that the first electronic component provided on the first housing 111 and the second electronic component provided on the second housing 121 can be rotated relative to each other about the pivot axis 1301. The movement state of the first housing 111 may be identical to the movement state of the first body assembly 110 and the movement state of the second housing 121 may be identical to the movement state of the second body assembly 120 in the embodiment of the present application. Since the edges of the first and second cases 111 and 121 are hinged by the hinge mechanism 130, the first and second cases 111 and 121 may be in a stacked state or may be in a unfolded state to have an included angle.

For example, when the electronic device 100 is folded, the angle between the first body component 110 and the second body component 120 may approach 0 °, and two surfaces (such as the light-emitting surface of the display 112 and the keyboard 122) on the first body component 110 and the second body component 120 that form the angle are close to each other. When the electronic device 100 is in the folded state, the display 112 and the keyboard 122 may be accommodated in the accommodating space formed by the first case 111 and the second case 121.

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 approximately 90 ° to 180 °, or more, and 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 112 and the keyboard 122) are far away from each other. When the electronic device 100 is in an open state, the display 112 and input devices (e.g., the keyboard 122 and the touchpad 123) may be exposed for use by a user.

In some embodiments, when the angle between the first body assembly 110 and the second body assembly 120 is greater than a predetermined angle, the first body assembly 110 may remain in any position during rotation of the first body assembly 110 relative to the second body assembly 120 about the pivot axis 1301.

When the included angle between the first body assembly 110 and the second body assembly 120 is smaller than or equal to the preset angle, the first body assembly 110 is in an unbalanced state, and can be automatically closed to the second body assembly 120, so that the electronic device 100 is in a folded state.

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

Of course, in some embodiments, the angle between the first body component 110 and the second body component 120 may be considered as the angle between the plane of the light emitting surface of the display 112 and the plane of the striking surface of the keyboard 122.

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 housing 111 and the second housing 121. Specifically, the included angle may be an included angle between a plane in which the first housing 111 is located and a plane in which the second housing 121 is located. In the embodiment of the present application, the plane in which the first housing 111 is located may be regarded as the plane in which the portion of the first housing 111 having the largest area is located (may also be referred to as the main plane of the first housing 111), and similarly, the plane in which the second housing 121 is located may be regarded as the plane in which the portion of the second housing 121 having the largest area is located (may also be referred to as the main plane of the second housing 121).

It should be noted that, the electronic device disposed on the first body assembly 110 side and the electronic device disposed on the second body assembly 120 side may be identical, may be partially identical, or may be completely different, which is only described as an example.

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, with a light exit surface of the first display screen facing a light exit surface of the second display screen when the electronic device is folded. Thus, the electronic device 100 is a dual-screen device.

It should be understood that fig. 1 only schematically illustrates some of the components included in the electronic device 100, the shape, size, and configuration of which are not limited by fig. 1. In other embodiments, electronic device 100 may include more or less components than those illustrated, as embodiments of the application are not limited. In other embodiments, the electronic device 100 may be of different types, and the electronic device 100 may include different components, and the structure of the electronic device provided in the embodiments of the present application is merely illustrative.

In addition to the mechanical connection between the first body assembly 110 and the second body assembly 120 via the hinge mechanism 130, in some embodiments, the first body assembly 110 and the second body assembly 120 may require an electrical connection to transmit signals between the first body assembly 110 and the second body assembly 120.

At present, two main modes for realizing electrical connection are available, one is to connect electrical functions through a flexible cable (cable), and the other is to connect electrical functions through a flexible circuit board (flexible printed circuit, FPC). For convenience of understanding, an example of an LCD driving board for controlling driving of an LCD display panel will be described below for a simple description of its electrical connection.

In one case, the LCD driving panel is located at one side (i.e., display end) of the first body assembly 110, and the LCD driving panel and the display screen are located on the same housing part, and the LCD driving panel may be electrically connected to electronic components such as a micro control unit (microcontroller unit, MCU) at one side of the second body assembly 120 through a flexible cable.

Since the LCD driving panel is disposed on the screen side (e.g., below the display screen 112 on the first body assembly 110 in fig. 1), the LCD driving panel occupies a displayable area of the display screen, so that the displayable area ratio on the screen side is difficult to be continuously increased, and the display experience is affected. In addition, the flexible cable is connected with the LCD drive plate through the connector, and the flexible cable and the connector occupy the thickness space of the screen side, so that the thickness of the machine body of the screen side is difficult to continuously reduce, and the appearance experience is influenced.

In order to increase the screen ratio of the display screen and to achieve light and thin display screen, alternatively, an LCD driving board may be disposed on one side of the second body assembly 120 (i.e., a keypad end), and the LCD driving board and the display screen may be disposed on different housing parts, so that the LCD driving board may be electrically connected to electronic components such as the LCD display screen on one side of the first body assembly 110 through a flexible circuit board.

For example, the first body assembly 110 and the second body assembly 120 are mechanically connected by a hinge mechanism 130 of a watch chain type, and the flexible circuit board passes through a slit in the center of the hinge mechanism 130 to connect the electrical functions of the first body assembly 110 side and the second body assembly 120 side, wherein the slit channel of the hinge mechanism 130 can restrict the movement form of the flexible circuit board 101 and function to protect the flexible circuit board. In this way, although the slot channel of the hinge mechanism 130 can restrict the movement of the flexible circuit board FPC, the hinge mechanism needs to be matched with the watch chain hinge mechanism, and the watch chain hinge has a complex structure and high cost. The flexible circuit board is directly rubbed with the metal hinge mechanism, and the damage risk is high. And the hinge structure is larger in size when the cable passes through the hinge gap channel, so that the electronic equipment is not easy to lighten and thin.

For another example, the second body assembly 120 includes a folder bracket to which the LCD driving panel is fixed. One end of the flexible circuit board is connected to the LCD driving board, and the other end of the flexible circuit board is connected to the electronic components in the first body assembly 110 by bypassing the hinge mechanism 130 after extending one turn around the circumference of the folding bracket, wherein the initial extending direction of the other end of the flexible circuit board is the opening direction of the first body assembly 110. The flexible circuit board FPC located in the receiving space of the second body assembly 120 may be free to float as the first body assembly 110 rotates about the pivot axis of rotation with respect to the second body assembly 120. In this manner, the force on the flexible circuit board is reduced because the flexible circuit board is in a free floating state within the cavity of the second body assembly 120 to avoid the flexible circuit board being tensioned. However, when the electronic device is closed, the flexible circuit board located at the hinge mechanism 130 may arch, which may easily cause severe compression of the flexible circuit board, thereby causing breakage of the flexible circuit board.

Therefore, the embodiment of the application provides a swing rod mechanism, a connecting assembly and electronic equipment, which can restrict the movement form of a flexible circuit board (FPC), so that the reliability of the electrical connection of the FPC is improved.

Referring to fig. 2-5, the electronic device 200 includes a first body assembly 110, a second body assembly 120, a hinge mechanism 130, and a connection assembly 140.

The first body assembly 110 includes a first housing 111 and a first electronic component 1101. The first case 111 is formed with a first accommodation space in which the first electronic component 1101 is accommodated.

The material of the first housing 111 may be a metal material, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, austenitic stainless steel, etc.; but also non-metallic materials such as carbon fiber, polycarbonate (PC), engineering plastics, glass, ceramics, wood, leather, sapphire, composites, etc.

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

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 in which the second electronic component 1201 is accommodated. The exhaust hole 1202 is provided at one end of the second housing 121 connected to the first housing 111, for exhausting the gas of the second accommodating space, and achieving heat dissipation.

The material of the second housing 121 may be a metal material, such as aluminum alloy, magnesium alloy, aluminum-magnesium alloy, titanium alloy, austenitic stainless steel, etc.; but also non-metallic materials such as carbon fiber, polycarbonate (PC), engineering plastics, glass, ceramics, wood, leather, sapphire, composites, etc.

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

The second electronic component 1201 is any one of components electrically connected to the first electronic component 1101. The second electronic component 1201 may be, for example, a display screen driver board.

The hinge mechanism 130 is hinged between the first body assembly 110 and the second body assembly 120, and the first body assembly 110 is rotatable about a swivel pivot axis 1301 (i.e., hinge axis) relative to the second body assembly 120 by 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 are rotatable relative to each other about a rotation pivot axis 1301 of the hinge mechanism 130.

The connection assembly 140 includes a flexible circuit board 141 and a swing link mechanism 142.

The flexible circuit board 141 includes a first end 1411, a second end 1412, and an intermediate section 1413 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 an embodiment of the application, the first end 1411 is coupled to the first electronic component 1101 on the first housing 111 and the second end 1412 is coupled to the second electronic component 1201 on the second housing 121, bypassing the hinge mechanism 130.

It should be noted that, the fixing may be understood as being relatively fixed, for example, the second end 1412 is a fixed end, and it may be understood that the second end 1412 is fixed relative to the second housing 121 (or the second electronic element 1201).

In an embodiment of the present application, the hinge mechanism 130 may have a curved surface. A portion of the flexible circuit board 141 near the first end 1411 may be wound around the curved surface when the first housing 111 rotates relative to the second housing.

As shown in fig. 4 and 5, an opening (shown in a dotted line area in fig. 6) is formed at an end of the second housing 121 to which the first housing 111 is connected, and an intermediate section 1413 of the flexible circuit board 141 extends from the second accommodation space, bypasses the curved surface of the hinge mechanism 130, and enters the first accommodation space of the first housing 111. Upon rotation of the first and second housings 111, 121 relative to each other about the pivot axis 1301 of the hinge mechanism 130, the intermediate section 1413 of the flexible circuit board 141 extends from or into the second accommodation space from the opening.

It should be noted that, in the rotation process of the first housing 111 relative to the second housing 121, the flexible circuit board 141 and the structural member at the opening generate relative sliding and friction, so in the embodiment of the present application, a lubrication component may be disposed at the contact area between the opening and the flexible circuit board 141, and the friction force applied to the flexible circuit board 141 is reduced by the lubrication component, so as to achieve the purpose of preventing the abrasion of the flexible circuit board 141. Illustratively, the lubrication component may be a teflon tape.

As shown in fig. 5, the opening and swing link mechanism 142 is provided in a middle region of an end of the second housing 121 to which the first housing 111 is connected, and a length of the opening and swing link mechanism 142 along the rotation pivot axis 1301 corresponds to a width of the flexible circuit board 141 (i.e., a dimension of the flexible circuit board 141 in the rotation pivot axis 1301 direction).

The swing link 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 as the first housing 111 rotates relative to the second housing 121 about the pivot axis 1301 (i.e., as the first end 1411 of the flexible circuit board moves relative to the second end 1412 of the flexible circuit board).

In the embodiment of the present application, the swing rod mechanism 142 applies a pulling force to the flexible circuit board 141. In some embodiments, the pulling force is at an obtuse or a flat angle to the direction of movement of the flexible circuit board 141 when the first body assembly 110 is opened relative to the second body assembly 120, such that the pulling force has a force component in the direction of movement of the flexible circuit board, or the direction of the pulling force is opposite to the direction of movement 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 action on the flexible circuit board 141.

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, 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, the second end 1412 is subjected to the force of the second body assembly 120, the middle section 1413 of the flexible circuit board 141 is pulled by the swing link mechanism 142, and the middle section 1413 is subjected to the pulling force of the swing link mechanism 142. The flexible circuit board 141 can be balanced under the combined action of the above forces.

Alternatively, the direction of the pulling force applied by the swing link 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 may have a force component in the moving direction of the flexible circuit board, which is opposite to the direction of the force applied by the first body assembly 110 to the first end 1411.

It should be noted that, the force applied to the first end 1411 by the first body assembly 110 referred to herein may be understood as an equivalent force applied to the first end 1411, or as an equivalent force applied to a portion of the flexible circuit board adjacent to the first body assembly, except for the first body assembly 110. Reference herein to the direction of movement of the flexible circuit board is to be understood as the direction of movement of the flexible circuit board between the first end 1411 and the swing link mechanism 142.

FIG. 6 is a schematic view of a swing link mechanism according to an embodiment of the present application, wherein the swing link member is in a first position; FIG. 7 is a schematic view of a swing link mechanism according to an embodiment of the present application, wherein the swing link member is in a second position; FIG. 8 is an exploded view of a swing link mechanism according to an embodiment of the present application; the first position corresponds to the position of the swing rod element when the electronic equipment is in a closed state and is also called an initial position; the second position is the position of the pendulum element when the electronic device is at the maximum opening angle, also called end position.

As shown in fig. 6-8, in an embodiment of the present application, the swing link mechanism 142 may include a base 1421, a swing link member 1422, and a resilient member 1423.

Illustratively, the base 1421 and the swing link member 1422 may be made of plastic materials, and the elastic member 1423 may be made of metal materials such as copper or nylon.

The base 1421 is disposed on a side of the second housing 121 adjacent to the first housing 111, and a specific position may refer to an example position shown in fig. 5. Illustratively, mounting holes 1424 are provided on the base 1421, and the base 1421 may be fixed to the second housing 121 by the mounting holes 1424 and fasteners.

A swing link member 1422 and an elastic member 1423 are mounted on the base 1421, the swing link member 1422 being rotatable relative to the base between an initial position and an end position, the elastic member 1423 being configured to apply an elastic force to the swing link member 1422 to return the swing link member 1422 to the initial position.

Here, the fact that the swing link member 1422 is rotatable relative to the base 1421 between the initial position and the final position means that the swing link member 1422 is rotatable relative to the base 1421 from the initial position (the position shown in fig. 3 and 6) to the final position (the position shown in fig. 2 and 7), or from the final position back to the initial position, or from the initial position to the target position, or from the target position back to the initial position. Wherein the target position is an arbitrary position between the initial position and the end position.

Further, in the embodiment of the present application, a first stop portion 1425 and a second stop portion 1426 are further provided on the base 1421. When the swing link member 1422 is located at the initial position, the swing link member 1422 abuts against the first stopper 1425, and the swing link member 1422 is maintained at the initial position by the stopper of the first stopper 1425 and the elastic force of the elastic member. When the swing link member 1422 is at the end position, the swing link member 1422 abuts against the second stopper 1426, and the swing link member 1422 is maintained at the end position by the stopper of the second stopper 1426 and the pulling of the flexible circuit board 141 (the force applied to the first end 1411 from the first body assembly 110). When the swing link member 1422 is located at an arbitrary position between the initial position and the final position, balance can be achieved by pulling of the elastic member 1422 and the flexible circuit board 141, and is maintained at this position.

As can be seen from the foregoing, in the embodiment of the present application, the swing link mechanism 142 increases the stop at both the initial position (the position shown in fig. 6) and the final position (the position shown in fig. 7) of the swing link member 1422, so as to ensure the stability during the movement, and limit the movement range of the swing link member 1422 between the initial position and the final position.

It should be appreciated that the first stop 1425 and the second stop 1426 may take a variety of suitable shapes. Illustratively, the first and second stops 1425, 1426 take the form of suitable plates or blocks. The first stopping portion 1425 has a smaller size, and one first stopping portion is respectively disposed at each end of the base 1421. The second stopper 1426 has a large size, for example, corresponding to the width of the flexible circuit board 141. Of course, the shape and size of the first and second stoppers 1425 and 1426 are not limited to those shown in fig. 6 to 8, as long as the stopping effect can be achieved.

It should also be appreciated that the base 141 may be of unitary construction or may be of removable construction.

Illustratively, in an embodiment of the present application, the swing link member 1422 includes a rotational shaft 1427 and a rotational portion 1428 coupled to the rotational shaft 1427. A rotation shaft hole is provided on the base 1421, and the swing link member 1422 may be mounted on the base 1421 by inserting both ends of the rotation shaft 1427 into the corresponding rotation shaft holes. The swing link member 1422 or the rotating portion 1428 is rotatable about the axis of the rotation shaft 1427 relative to the base 1421 between an initial position and an end position.

Illustratively, in embodiments of the present application, the rotating portion 1428 has a plate-like structure, and a portion of the middle section 1413 of the flexible circuit board 141 is fixed to a surface of the rotating portion 1428, for example, a surface of the rotating portion 1428 on a side close to the second electronic component 1201. Thus, the rotation of the swing link member 1422 or the rotation portion 1428 can plan the movement path of the flexible circuit board 141, so that the flexible circuit board is not easy to arch and squeeze, and breakage failure caused by the arch and squeeze is avoided. Illustratively, in the embodiment of the present application, the pivot shaft 1427 and the pivot shaft portion 1428 are integrally formed, i.e., the swing link member 1422 is an integrally formed structure.

Illustratively, in an embodiment of the present application, the elastic member 1423 may be a torsion spring, for example, a torsion spring with a coil structure, in which a coil is sleeved on the rotating shaft 1427 of the swing rod member 1422, and the fixed end is mounted on the base 1421, and the free end abuts against the rotating portion 1428 of the swing rod member 1422. The elastic member 1423 is provided in a state of continuously applying an elastic force to the swing link member 1422 during the movement of the swing link member 1422, which force prevents the swing link member 1422 from rotating from the initial position to the final position. I.e. the elastic force gives the pendulum member 1422 a tendency to return to the original position. The initial position is a position (e.g., the state shown in fig. 3 and 6) where the included angle between the swing link member 1422 and the base 1421 is the largest, and corresponds to the position of the swing link member 1422 when the electronic device 200 has the smallest opening/closing angle. The end position is a position (for example, the position shown in fig. 2 and 7) where the angle between the swing link member 1422 and the base 1421 is the smallest, and corresponds to the position of the swing link member 1422 when the electronic device 200 is at the largest opening/closing angle.

The angle between the swing link member 1422 and the base 1421 is defined as the angle between the plane of the largest area of the swing link member 1422 and the plane of the mounting surface of the base 1421. The mounting surface of the base 1421 refers to a plane in which the mounting hole 1424 is disposed.

The maximum and minimum angles between the rocker member 1422 and the base 1421 (or horizontal plane) depend on the angle between the first stop 1425 and the second stop 1426. And the angle between the first and second stoppers 1425 and 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 and second housings 111 and 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, the included angle between the first stop portion 1425 and the second stop portion 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 maximum (the first housing 111 of the electronic device 200 is flattened relative to the second housing 121), the included angle between the first stopping portion 1425 and the second stopping portion 1426 is about 120 degrees.

Here, the angle between the first and second stoppers 1425 and 1426 refers to an angle between surfaces of the first and second stoppers 1425 and 1426 opposite to each other.

Illustratively, in embodiments of the present application, the swing link member 1422 or the rotating portion 1428 may be rotated between 0 and 120 degrees.

With continued reference to fig. 2 and 5, in an embodiment of the present application, the swing link element 1422, i.e., both ends of the swing link mechanism 142, are disposed in the direction of the pivot axis 1301 of rotation. A partial region of the intermediate section 1413 of the flexible circuit board 141 is fixed to a surface of the swing link member 1422, for example, to a side surface of the rotating portion 1428. Illustratively, it may be secured by a suitable adhesive.

Here, the rotation shaft 1427 of the swing link member 1422 may include a center line (or axis) parallel to the rotation pivot axis 1301.

In some embodiments, the placement of the rocker element 1422 is within the stacking range of the flexible circuit board 141. The stacking range of the flexible circuit board referred to herein may be understood as a movement region of the portion of the flexible circuit board where the morphology change is greatest during the relative rotation of the first housing 111 and the second housing 121.

When the first body assembly 110 rotates about the rotation pivot axis 1301 with respect to the second body assembly 120, 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 partial region of the middle section 1413 of the flexible circuit board 141 is fixed to the surface of the swing link member 1422, the flexible circuit board 141 moves together with the swing link member 1422 by the combined action of the elastic member 1423 and the first body assembly 110. During this process, the spring member 1423 applies a force to the swing link member 1422 to resist movement, thereby slightly tightening the flexible circuit board 141 during movement to remain flat. And the rotation of the swing link member 1422 defines a movement path of the flexible circuit board 141 so that it is not easily arched and pressed, preventing the flexible circuit board 141 from breaking and failing due to the occurrence of the arching and pressing.

For example, when the electronic device is opened, the first body assembly 110 rotates relative to the second body assembly 120 in an opening direction (e.g., clockwise in fig. 2), and the flexible circuit board 141 is also moved in the opening direction (i.e., protrudes from the second cavity) by the first body assembly 110, for example, around a curved surface of the hinge mechanism 130. Meanwhile, the swing link member 1422 rotates from the initial position (for example, in the anticlockwise direction in fig. 3) under the action of the flexible circuit board 141, at this time, the elastic force of the elastic member 1423 makes the swing link member 1422 have a tendency to rotate clockwise, so that the swing link member 1422 forms a pulling force on the flexible circuit board 141, and thus the flexible circuit board 141 is slightly stretched during movement under the action of the first body component 110 and the swing link member 1422, and the flatness of the flexible circuit board 141 during movement is ensured. Meanwhile, as the partial area of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing rod element 1422, the rotation of the swing rod element 1422 can limit or plan the movement path of the flexible circuit board 141, so that the flexible circuit board 141 is not easy to arch and squeeze, and the flexible circuit board 141 is prevented from being broken and failed due to the arch and squeeze.

For example, when the electronic device is closed, the first body assembly 110 rotates relative to the second body assembly 120 in a closing direction (e.g., in a counterclockwise direction in fig. 3), at which time the force of the first body assembly 110 against the flexible circuit board 141 gradually decreases, and the swing link member 1422 also moves in a direction of the initial position (e.g., clockwise in fig. 3) under the action of the elastic member 1423, and simultaneously drives the flexible circuit board 141 to move in that direction. At this time, since the partial region of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing link member 1422, and the swing link member 1422 has a pulling force on the flexible circuit board 141, it is ensured that the flexible circuit board 141 is slightly tensioned during the movement to maintain flatness during the movement. Thus, the portion of the flexible circuit board 141 located outside the second receiving chamber is abutted against the curved surface of the hinge mechanism 130 without being arched or pressed by the swing link member 1422. And the flexible circuit board portion entering the inside of the second accommodation chamber is not easily arched and pressed because the movement path of the flexible circuit board 141 is defined or planned by the rotation of the swing link member 1422, so that the flexible circuit board 141 is prevented from being broken and failed due to the occurrence of the arching and pressing.

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 flexible circuit board 141 is constrained in movement form and path by the swing rod mechanism 142, so as to realize the back and forth controlled movement of the flexible circuit board. The flexible circuit board 141 can be kept flat and stressed uniformly in the movement process, so that the service life of the flexible circuit board 141 can be prolonged, and the long-term reliability of the flexible circuit board 141 is improved.

FIG. 11 is a schematic view of a swing link mechanism according to another embodiment of the present application, wherein the swing link member is in a first position; FIG. 12 is a schematic view of a swing link mechanism according to another embodiment of the present application, wherein the swing link mechanism is in a second position; FIG. 13 is an exploded view of a swing link mechanism according to another embodiment of the present application, wherein the first position is the position of the swing link element when the electronic device is in the closed state, which is also referred to as the initial position; the second position is the position in which the pendulum element is in when the electronic device is in the maximally open state, also called end position.

Referring to fig. 9-13, the electronic device 300 includes a first body assembly 110, a second body assembly 120, a hinge mechanism 130, and a connection assembly 140. The connection assembly 140 includes a flexible circuit board 141 and a swing link mechanism 242.

The electronic device 300 is substantially identical to the electronic device 200 in structure, except that the swing link mechanism 242 of the electronic device 300 is different from the swing link mechanism 142 of the electronic device 200.

As shown in fig. 11-13, in an embodiment of the present application, the swing link mechanism 242 may include a base 2421, a swing link element 2422, and a resilient element 2423.

The base 2421 is provided at a side of the second housing 121 close to the first housing 111, and a specific position may be referred to as an example position shown in fig. 5. Illustratively, mounting holes 2424 are provided on the base 2421, and the base 2421 may be fixed to the second housing 121 by the mounting holes 2424 and fasteners.

The swing link member 2422 and the elastic member 2423 are mounted on the base 2421 such that the swing link member 222 can be rotated relative to the base between the initial position and the final position, and the elastic member 2423 is configured to apply an elastic force to the swing link member 2422 to return the swing link member 2422 to the initial position.

Here, the fact that the swing link member 2422 is rotatable relative to the base 2421 between the initial position and the final position means that the swing link member 2422 is rotatable relative to the base 2421 from the initial position (the position shown in fig. 11) to the final position (the position shown in fig. 12), or from the final position back to the initial position, or from the initial position to the target position, or from the target position back to the initial position. Wherein the target position is an arbitrary position between the initial position and the end position.

Further, in the embodiment of the present application, a first stop 2425 and a second stop 2426 are further provided on the base 2421. When the swing link member 2422 is located at the initial position, the swing link member 2422 abuts on the first stopper 2425, and the swing link member 2422 is held at the initial position by the stopper of the first stopper 2425 and the elastic force of the elastic member. When the lever member 2422 is at the end position, the lever member 2422 abuts against the second stopper 2426, and the lever member 2422 is held at the end position by the stopper of the second stopper 2426 and the pulling of the flexible circuit board 141 (the force applied to the first end 1411 from the first body assembly 110). When the swing link member 2422 is located at an arbitrary position between the initial position and the final position, balance can be achieved by the pulling of the elastic member 2423 and the flexible circuit board 141, and is maintained at this position.

As can be seen from the foregoing, in the embodiment of the present application, the swing link mechanism 242 increases the stop at both the initial position (the position shown in fig. 11) and the final position (the position shown in fig. 12) of the swing link member 2422, ensures the stability during the movement, and limits the movement range of the swing link member 2422 between the initial position and the final position.

It should be appreciated that the first stop 2425 and the second stop 2426 can take a variety of suitable shapes and sizes. Illustratively, the first and second stops 2425, 2426 take the form of suitable plates or blocks. The first stoppers 2425 are inclined plates having a smaller size, and one first stopper 2425 is provided at each end of the base 2421. The second stop 2426 is a flat plate with a larger size, for example, corresponding to the width of the flexible circuit board 141. Of course, the shape and size of the first and second stoppers 2425 and 2426 are not limited to those shown in fig. 11 to 13, as long as the stopping effect can be achieved. For example, the first stop 2425 can also be a planar structure as shown in fig. 14.

It should also be appreciated that the base 241 may be of an integrally formed construction or may be of a removable construction.

Illustratively, in an embodiment of the present application, the rocker element 2422 includes a rotational shaft 2427 and a rotational portion 2428 coupled to the rotational shaft 2427. A rotation shaft hole is provided on the base 2421, and the swing link member 2422 can be mounted on the base 2421 by inserting the rotation shaft 2427 into the corresponding rotation shaft hole. The swing link member 2422 or the rotation portion 2428 is rotatable relative to the base 2421 about the axis of the rotation shaft 2427 between the initial position and the end position.

Illustratively, the shaft 2427 and the shaft portion 1428 are formed separately in embodiments of the present application. Namely, the rotation shaft 2427 of the swing link member 2422 and the rotation shaft part 2428 are assembled together, and are not integrally formed.

In the embodiment of the present application, a through hole is formed in the rotation part 2428, and the size of the through hole is matched with that of the rotation shaft 2427, and the rotation shaft 2427 can be connected with the rotation part 2428 through the through hole, which can be in a rotation connection or a fixed connection. A rotation shaft hole is provided on the base 2421, and the rotation shaft 2427 and the swing link element 2422 can be mounted on the base 2421 by inserting both ends of the rotation shaft 2427 into the corresponding rotation shaft holes. The pendulum member 2422 is rotatable about the rotary shaft 2427 or the axis of the rotary shaft relative to the base 2421 between an initial position (the position shown in fig. 11) and an end position (the position shown in fig. 12).

Illustratively, in the embodiment of the present application, the rotation part 2428 has a plate-like structure, and a part of the middle section 1413 of the flexible circuit board 141 is fixed on a surface of the rotation part 2428, for example, a surface of the rotation part 2428 on a side close to the second electronic component 1201. Thus, the rotation of the swing link member 2422 or the rotation part 2428 will plan the movement path of the flexible circuit board 141, so that it is not easy to arch and squeeze to cause fracture failure.

Illustratively, in the embodiment of the present application, the elastic member 2423 may employ a torsion spring, for example, a coil structure torsion spring, whose coil is sleeved on the rotation shaft 2427 of the swing link member 2422, the fixed end is mounted on the base 2421, and the free end abuts against the rotation portion 2428 of the swing link member 2422. The elastic member 2423 is provided in a state where an elastic force is continuously applied to the swing link member 2422 during the movement of the swing link member 2422, the force preventing the swing link member 2422 from rotating from the initial position to the final position. I.e. the elastic force gives the pendulum member 2422 a tendency to return to the original position. The initial position is a position (for example, the position shown in fig. 10 and 11) where the angle between the swing link member 2422 and the base 2421 is the largest, and corresponds to the position of the swing link member 2422 when the electronic device 300 is at the smallest opening/closing angle. The end position is a position (e.g., the position shown in fig. 9 and 12) where the angle between the swing link member 1422 and the base 2421 is the smallest, and corresponds to the position of the swing link member 2422 when the electronic device 300 is at the largest opening/closing angle.

The maximum and minimum angles between the pendulum member 2422 and the base 2421 (or horizontal planes) depend on the angle between the first stop 2425 and the second stop 2426. And the angle between the first and second stoppers 2425 and 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 and second housings 111 and 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, the included angle between the first stop portion 2425 and the second stop portion 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 maximum (the first housing 111 of the electronic device 300 is flattened relative to the second housing 121), the included angle between the first stop portion 2425 and the second stop portion 2426 is about 120 degrees.

Here, the angle between the first and second stoppers 2425 and 2426 refers to an angle between surfaces of the first and second stoppers 2425 and 2426 that are opposite to each other.

Illustratively, in embodiments of the present application, the rocker element 2422 or the swivel 2428 may swivel between 0 and 120 degrees.

As shown in fig. 15, a state diagram of the connection assembly 140 corresponding to 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 is shown.

As shown in fig. 16, a state diagram of the connection assembly 140 corresponding to the open state and the closed state of the electronic device is shown when the opening/closing angle of the electronic device 300 is 135 degrees or close to 135 degrees.

It can be seen from fig. 15 and 16 that the larger the maximum angle between the swing link member 2422 and the base 2421 (or horizontal plane), the larger the opening and closing angle of the electronic device 300.

In the present embodiment, the swing link element 2422, i.e. both ends of the swing link mechanism 242, are placed in the direction of the pivot axis 1301. A partial region of the intermediate section 1413 of the flexible circuit board 141 is fixed on the surface of the swing link element 2422, for example, on one side surface of the rotation part 2428. Illustratively, it may be secured by a suitable adhesive.

Here, the rotation shaft 2427 of the swing link element 2422 may include a center line (or axis) that is parallel to the rotation pivot axis 1301.

In some embodiments, the arrangement position of the swing link element 2422 is within the stacking range of the flexible circuit board 141. The stacking range of the flexible circuit board referred to herein may be understood as a movement region of the portion of the flexible circuit board where the morphology change is greatest during the relative rotation of the first housing 111 and the second housing 121.

When the first body assembly 110 rotates about the rotation pivot axis 1301 with respect to the second body assembly 120, 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 partial region of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing link member 2422, the flexible circuit board 141 moves together with the swing link member 2422 by the combined action of the elastic member 2423 and the first body assembly 110. During this process, the elastic member 2423 applies a force to the rocker member 2422 to resist its movement, thereby causing the flexible circuit board 241 to be slightly stretched during movement to remain flat. And the rotation of the swing link member 2422 defines the movement path of the flexible circuit board 141 so that it is not easily arched and pressed, preventing the flexible circuit board 141 from being broken and failed due to the occurrence of the arching and pressing.

For example, when the electronic device is opened, the first body assembly 110 rotates in an opening direction (e.g., clockwise in fig. 9) with respect to the second body assembly 120, and the flexible circuit board 141 is also moved in the opening direction (i.e., protrudes from the second accommodating chamber) by the first body assembly 110, and is wound around the curved surface of the hinge mechanism 130. The swing link member 2422 rotates under the force of the flexible circuit board 141 (e.g. in the counterclockwise direction in fig. 9), and the elastic force of the elastic member 2423 causes the swing link member 2422 to rotate clockwise, so that the swing link member 2422 forms a pulling force on the flexible circuit board 141, thus the flexible circuit board 141 is slightly tightened during the movement under the action of the first body assembly 110 and the swing link member 2422, and the flatness of the flexible circuit board 141 during the movement is ensured. Meanwhile, since the partial area of the middle section 1413 of the flexible circuit board 141 is fixed on the surface of the swing link member 2422, the rotation of the swing link member 2422 can limit or plan the movement path of the flexible circuit board 141, so that the flexible circuit board 141 is not easy to arch and squeeze, and thus the flexible circuit board 141 is prevented from being broken and failed due to the arch and squeeze.

For example, when the electronic device is closed, the first body assembly 110 rotates relative to the second body assembly 120 in a closing direction (e.g., in a counterclockwise direction in fig. 10), at which time the force of the first body assembly 110 on the flexible circuit board 141 gradually decreases, and the swing link member 2422 moves in a direction of the initial position (e.g., in a clockwise direction in fig. 10) under the action of the elastic member 2423, and simultaneously drives the flexible circuit board 141 to move in that direction. At this time, since the partial region of the middle section 2413 of the flexible circuit board 141 is fixed on the surface of the swing link member 2422, and the swing link member 2422 has a pulling force on the flexible circuit board 141, it is ensured that the flexible circuit board 141 is slightly tensioned during the movement to maintain flatness during the movement. Thus, the portion of the flexible circuit board 141 located outside the second receiving chamber is abutted against the curved surface of the hinge mechanism 130 without being arched or pressed by the swing lever member 2422. The flexible circuit board 141 entering the second accommodating chamber is not easily arched and pressed because the movement path of the flexible circuit board 141 is limited or planned by the rotation of the swing rod member 2422, so that the flexible circuit board 141 is prevented from being broken and failed due to the arching and pressing.

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 flexible circuit board 141 is constrained in movement form and path by the swing rod mechanism 242, so as to implement the back and forth controlled movement of the flexible circuit board. The flexible circuit board 141 can be kept flat and stressed uniformly in the movement process, so that the service life of the flexible circuit board 141 can be prolonged, and the long-term reliability of the flexible circuit board 141 is improved.

It should be understood that the above-described embodiments are merely illustrative of the principles of the present application and are not limited to specific configurations, e.g., the swing link mechanism is not limited to the configurations described above, but may be variously modified.

The above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
