[0051] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0052] like Figure 1 and Figure 2 As shown, this embodiment provides an electronic device, including:

[0053] First ontology 101;

[0054] A second body 102;

[0055] The shaft module 103 is used to connect the first body 101 and the second body 102 so that they can rotate relative to each other;

[0056] The connection module 104 includes:

[0057] At least one first connection terminal 1041, used to connect to the first body 101;

[0058] at least one second connection terminal 1042, used to connect to the second body 102;

[0059] The circuit board 1043 is respectively connected to the at least one first connection terminal 1041 and the at least one second connection terminal 1042 , and is arranged in a non-planar manner along the axial direction of the rotating shaft module 103 .

[0060] The electronic device provided in this embodiment can be various types of devices with two bodies. For example, the electronic device can be a laptop computer, a tablet computer with two bodies, or a laptop and tablet computer two-in-one.

[0061] In this embodiment, the first body 101 and the second body 102 can be any two modules connected by a rotating shaft.

[0062] In some embodiments, the first body 101 and the second body 102 respectively include a shell, in which various modules are arranged, for example, a display module and / or an input module. Specifically, an input module is arranged in the first body 101, and a display module is arranged in the second shell; or a first display module is arranged in the first body 101, and a second display module is arranged in the second shell. The input module includes but is not limited to: a keyboard module and / or a touch panel and other devices with input functions. Figure 6 It is a schematic structural diagram of an electronic device in which a first body 101 and a second body 102 both include display modules.

[0063] The first display module and the second display module may include: various types of display screens. For example, according to whether they are bendable, the display screen may include: a flexible display module and a rigid display module. According to the display principle, the display screen may include: a liquid crystal display module, an organic light emitting diode (OLED) display module, an electronic ink display module, or a projection display module. In some embodiments, the first display module and the second display module may be two completely independent modules. In other embodiments, the first display module and the second display module may be different display areas of the same display module.

[0064] In this embodiment, the two bodies are physically connected through a hinge, and the first body 101 and the second body 102 can rotate relative to each other through the hinge module 103. For example, the angle between the first body 101 and the second body 102 can be switched from a first angle to a second angle, assuming that the first angle is 0 degrees; the second angle can be 180 degrees or 360 degrees. Figure 6 The diagram is a schematic diagram showing that the angle between the first body 101 and the second body 102 is 180 degrees.

[0065] The rotating shaft module 103 includes one or more rotating shafts. If the rotating shaft module 103 includes multiple rotating shafts, the multiple rotating shafts meet a parallel condition, such as being parallel or approximately parallel.

[0066] The direction of the rotating shaft module 103 may include an axial direction and a radial direction. The axial direction of the rotating shaft module 103 is parallel to the axial direction of the rotating shaft; and the radial direction of the rotating shaft module 103 is parallel to the radial direction of the rotating shaft.

[0067] In this embodiment, the rotating shaft is a cylinder, and the direction of the radius or diameter of the cross section of the cylinder is the radial direction. The axial direction is perpendicular to the radial direction and perpendicular to the direction of the circular cross section of the cylinder.

[0068] In this embodiment, the connection module 104 is used to establish an electrical connection between the first body 101 and the second body 102. The electrical connection can be used for the transmission of various electrical signals. The electrical signals here include but are not limited to: power supply signals and data signals. The data signal may include display data for display by the display module, etc.

[0069] The first connection terminal 1041 and the second connection terminal 1042 may include terminals such as gold fingers that can transmit power signals.

[0070] In this embodiment, if Figure 4A , Figure 4B and Figure 4C The circuit board 1043 includes: a main body 201, a first end 202 and a second end 203 located at both ends of the main body; here, at least one first connection terminal 1041 can be arranged at the first end 202; at least one second connection terminal 1042 can be arranged at the second end 203. In this embodiment, if the number of the first connection terminal 1041 and the second connection terminal 1042 is more than one, a plurality of first connection terminals 1041 are arranged in parallel at the first end 202; a plurality of second connection terminals 1042 are arranged in parallel at the second end 203.

[0071] In this embodiment, the length of the main body of the circuit board 1043 is greater than the length of the first end 202 and / or the length of the second end 203 .

[0072] In some embodiments, the circuit board 1043 is arranged along the axial direction: at least the main body of the circuit board 1043 is arranged along the axial direction.

[0073] In some embodiments, if the first connection terminal 1041 and the second terminal of the connection module 104 are not arranged at the ends of the circuit board 1043, but the transmission line of the circuit board 1043 is arranged at both ends of the circuit board 1043 in the form of a soft wire, then the circuit board 1043 is axially arranged so that the circuit board 1043 is axially arranged as a whole.

[0074] In this way, if the connection module 104 does not undergo deformation such as twisting, the first connection terminals 1041 are arranged in parallel at the first end 202 along the long side of the connection module 104, so that the plurality of first connection terminals 1041 are arranged flush at the end of the connection module 104. If the connection module 104 does not undergo deformation such as twisting, the second connection terminals 1042 are arranged in parallel at the second end 203 along the long side of the connection module 104, so that the plurality of second connection terminals 1042 are arranged flush at the end of the connection module 104.

[0075] The circuit board 1043 may include:

[0076] Substrate; wherein the substrate may be a plastic substrate, optionally a flexible substrate or an elastic substrate, and the substrate may be in the form of a thin sheet;

[0077] One or more transmission lines are arranged in parallel on the substrate; two ends of the transmission line are connected to the first connection terminal 1041 and the second connection terminal 1042 respectively.

[0078] In some embodiments, the circuit board 1043 is further provided with: an insulating layer, which covers the outside of the transmission line to achieve insulation isolation between the transmission line and the outside.

[0079] In this embodiment, the transmission lines on the circuit board 1043 can be arranged in a small size and densely laid. Compared with a single transmission line including a soft wire with an insulating layer, the number of transmission lines included in the circuit board 1043 per unit volume is much greater than the number of soft wires. In this way, the connection module 104 including the circuit board 1043 is used to replace the soft wire to establish the electrical connection between the first body 101 and the second body, which is conducive to achieving a thin and light electronic device.

[0080] In this embodiment, the circuit board 1043 is disposed along the rotating shaft, and the circuit board 1043 is non-planarly disposed along the axial direction, that is, the circuit board 1043 is not disposed along the axial direction in a planar shape.

[0081] The non-planar configuration includes but is not limited to a curved configuration and / or a bent configuration. For example, FIG. 4A to FIG. 4C To be bent along the axial direction, Figure 4D It is set along the axial curved surface.

[0082] For example, after the circuit board 1043 is laid along the axial direction, the circuit board 1043 is in the shape of a broken line or a curve in a cross section perpendicular to the axial direction.

[0083] The fold line may include: an L-shaped fold line, a V-shaped fold line, etc. The curve includes: regular curves such as various types of arc lines, or irregular curves such as wavy lines. For example, the curve is an O-shaped curve, a U-shaped curve, an arc of a fan-shaped outer arc, etc. Figure 4DAs shown, the cross section of the main body of the circuit board along the axis is a U-shaped curve.

[0084] In one case, the circuit board 1043 may be a flexible printed circuit (FPC), which can undergo flexible deformation under the action of external force. After the external force is removed, the flexible circuit board may maintain the flexible deformation caused by the external force, or may recover part of the deformation; but generally cannot return to its original state.

[0085] If the circuit board 1043 is a flexible circuit, it can be curled in a cross section perpendicular to the axial direction to form one or more curling rings. Figure 3 It is a schematic diagram showing that the circuit board of the connecting module 104 is arranged in an axial spiral in the accommodation space formed at the center of the rotating shaft of the rotating shaft module.

[0086] In some embodiments, the circuit board 1043 may not be a flexible circuit board, but an elastic circuit board; the elastic circuit board may undergo elastic deformation under the action of external force; the elastic deformation will automatically disappear under the action of external force, thereby restoring the elastic circuit board to its initial state.

[0087] In some other embodiments, the circuit board 1043 may also be a rigid circuit board, which is molded into the above-mentioned specific non-curved paving shape during the manufacturing process.

[0088] In this embodiment, the connection module 104 including the circuit board 1043 is used to replace the soft wire to make the electrical connection between the first body 101 and the second body 102. On the one hand, the thinness and dense laying characteristics of the transmission line on the circuit board 1043 can be used to better realize the lightness and thinness of the electronic device; on the other hand, the connection module 104 including the connection terminal is used to establish the connection between the first body 101 and the second body 102. When assembling the electronic device, there is no need to pay attention to the connection soft wire, and the connection module 104 including multiple connection terminals can be plugged in and out at one time, thereby simplifying the assembly of the electronic device. Thirdly, in this embodiment, the circuit board 1043 is arranged along the non-planar axial direction of the rotating shaft module 103, so that the connection board can be laid using any non-planar accommodation space in the axial direction, which is again conducive to the thinness of the electronic device. In addition, due to the non-planar arrangement of the circuit board 1043 in the axial direction, the area of ​​the circuit board 1043 can be increased, so that the area of ​​the circuit board 1043 is increased. When the size of the transmission line does not change, more transmission lines can be laid on the circuit board 1043, and the number of the first connection terminals 1041 and the second connection terminals 1042 at both ends can also be more. In this way, in the case where there are many electrical connections between the first body 101 and the second body 102, the circuit board 1043 can realize multiple connections between the first body 101 and the second body 102 while occupying as little space as possible in the electronic device.

[0089] In some embodiments, the circuit board 1043 has a first state and a second state;

[0090] In the first state, the connection module 104 is stretched along the axial direction, and the connection module 104 has a first length along the setting direction of the connection module 104;

[0091] In the second state, the connection module 104 is not stretched along the axial direction, and the connection module 104 has a second length along the setting direction of the connection module 104;

[0092] Wherein, the first length is greater than the second length.

[0093] In this embodiment, the connecting module 104 has at least two states. In the first state of these two states, there may be an external force pulling the circuit board 1043, so that the connecting module 104 has a first length in the setting direction based on elastic deformation, partially recoverable flexible deformation, or redundant structural design; and in the second state, the external force pulling the connecting module 104 is removed, and the connecting module 104 may switch the setting length in the setting direction to a second length based on its own elastic deformation, partially recoverable flexible deformation, etc.

[0094] In this embodiment, the external force may be applied by the first body 101 and / or the second body 102 .

[0095] In this embodiment, the setting direction of the connection module 104 includes:

[0096] The arrangement direction of the main body of the circuit board 1043;

[0097] a setting direction of the first end portion 202 where the at least one first connection terminal 1041 is located;

[0098] The arrangement direction of the second end portion 203 where the at least one second connection terminal 1042 is located.

[0099] The arrangement direction of the circuit board 1043 is the axial direction of the rotating shaft;

[0100] The first end portion 202 and the second end portion 203 may be disposed in opposite directions and both are perpendicular to the disposition direction (ie, the axial direction) of the main body of the circuit board 1043 .

[0101] Since the angles between the first body 101 and the second body 102 are different during the rotation of the first body 101 and the second body 102 based on the hinge module 103, the connection module 104 that establishes the electrical connection between the first body 101 and the second body 102 through the carding and / or contact of the connecting terminals may be pulled at some specific positions, so that the first body 101 and / or the second body 102 will apply external force to the connection module 104, causing the connection module 104 to switch between the first state and the second state.

[0102] Correspondingly, the main body of the circuit board 1043 has a first sub-state and a second sub-state; wherein, when the connection module 104 is in the first sub-state, the main body of the circuit board 1043 is in the first sub-state, at which time, the main body of the circuit board 1043 deforms itself so that the connection module 104 has a first length in the overall setting direction; when the connection module 104 is in the second sub-state, the main body of the circuit board 1043 is in the second sub-state, at which time, the main body of the circuit board 1043 recovers at least partially through its own deformation, so that the length of the connection module 104 in the overall setting direction is reduced, thereby having a second length. In this case, the first end portion 202 including the at least one first connection terminal 1041 and the second end portion 203 including the at least one second connection terminal 1042 do not deform themselves.

[0103] In other embodiments, Figure 4CAs shown, a first end portion 202 including at least one first connecting terminal 1041 and a second end portion 203 including at least one second connecting terminal 1042 are provided with a redundant structure, and the redundant structure has a third sub-state and a fourth sub-state; when the connecting module 104 is in the first state, the redundant structure has a third sub-state, and the redundant structure deforms itself so that the connecting module 104 has a first length in its overall setting direction; when the connecting module 104 is in the second state, the redundant structure has a fourth sub-state, and the redundant structure recovers all or part of its deformation so that the connecting module 104 has a second length smaller than the first length in its overall setting direction.

[0104] The connection module 104 provided in the embodiment of the present application has at least two states, which can meet the length required for electrical connection when the two main bodies are in different relative positions, thereby reducing the instability of the electrical connection caused by only a single length, as the single length cannot meet the maximum length of the two main bodies at a specific angle, and reduces the damage of the wire due to pulling.

[0105] In some embodiments, when the first body 101 is at a first angle relative to the second body 102, the connection module 104 is in the first state; when the first body 101 is at a second angle relative to the second body 102, the connection module 104 is in the second state; wherein the second angle is greater than the first angle.

[0106] In some embodiments, the first angle may be the angle at which the first body 101 and the second body 102 are buckled, and the first angle may be assumed to be 0 degrees; the second angle may be any angle greater than the first angle, for example, 180 degrees; if the two electronic devices are at 180 degrees, the first body 101 and the second body 102 are located in the same plane.

[0107] In some embodiments, the first angle is 0 degrees and the second angle may be 360 ​​degrees.

[0108] In some implementations, the circuit board 1043 is laid in a spiral along the axial direction.

[0109] like Figure 4B As shown, the circuit board 1043 is laid in a spiral along the axis. The spiral laying will cause the circuit board 1043 to have multiple spiral turns. Changes in the spacing between the spiral turns and / or changes in the ring diameter of the spiral turns will cause the length of the connection module 104 in its laying direction to change.

[0110] In some embodiments, the circuit board 1043 is undulating in a direction perpendicular to the axial direction and is laid along the axial direction. Figure 4AIt is shown that the circuit board 1043 is undulating along the axial direction.

[0111] In this embodiment, the circuit board 1043 is in an undulating shape, and the undulating shape may be composed of a plurality of arcs with the same undulation degree, or may be composed of a plurality of arcs with different undulation degrees.

[0112] In some embodiments, the rotating shaft module 103 has an axial accommodation space; the circuit board 1043 is located in the accommodation space and laid along the axial direction.

[0113] For example, the shaft module 103 includes a shaft center and a rotating drum that rotates relative to the shaft center; a hollow cavity is provided in the shaft center; the hollow cavity is the accommodation space, and in order to better utilize the space inside the electronic device, the circuit board 1043 is placed in the accommodation space and laid along the axial direction. The shaft center is provided with a first connection terminal 1041 and a second connection terminal 1042 that pass through to establish electrical connections with the first body 101 and the second body 102, respectively.

[0114] In some embodiments, the rotating shaft module 103 is axially laid outside the rotating shaft of the rotating shaft module 103 .

[0115] In this embodiment, the volume of some rotating shaft centers is very small, and no hollow cavity is provided in the rotating shaft centers, that is, the rotating shaft centers are solid shafts. In this case, the circuit board 1043 can be laid along the axial direction outside the rotating shaft.

[0116] For example, the circuit board 1043 is a flexible circuit board, and the flexible circuit board is disposed around the axial direction of the rotating shaft.

[0117] In some embodiments, the circuit board 1043 has at least two spiral turns and is laid in the axial direction in a spiral manner; two adjacent spiral turns partially overlap when the connection module 104 is in the first state and the second state.

[0118] In this embodiment, the connection module 104 has two states. In this embodiment, the circuit board 1043 is laid along the axial spiral, and forms one spiral circle after one rotation. In this embodiment, two adjacent spiral areas of the circuit board 1043 have overlapping parts when the connection module 104 switches between the first state and the second state. The only difference is the change in the size of the overlapping part. In this way, if the connection module 104 keeps the two adjacent spiral circles overlapping in the first state and the second state, the damage of the circuit board 1043 caused by the friction between the edges of the two adjacent spiral circles can be reduced.

[0119] When the connecting module 104 is in the first state, the overlapping dimension between two adjacent spiral turns of the circuit board 1043 is a first dimension; when the connecting module 104 is in the second state, the overlapping dimension between two adjacent spiral turns of the circuit board 1043 is a second dimension; the first dimension is smaller than the second dimension; thus, the increase from the first dimension to the second dimension causes the connecting module 104 to be reduced from a first length to a second length in its setting direction.

[0120] In some embodiments, the circuit board 1043 has at least two spiral turns, and is laid in the axial direction in a spiral manner; there is a distance between two adjacent spiral turns when the connection module 104 is in the first state and the second state. Since there is a distance between any two adjacent spiral turns when the connection module 104 is in the first state and the second state, the edges of the two adjacent spiral turns will not rub against each other, thereby causing damage to the circuit board 1043.

[0121] When the connecting module 104 is in the first state, the spacing between two adjacent spiral turns of the circuit board 1043 is a first spacing; when the connecting module 104 is in the second state, the spacing between two adjacent spiral turns of the circuit board 1043 is a second spacing; the first spacing is smaller than the second spacing; thus, the increase from the first spacing to the second spacing reduces the connecting module 104 from the first length to the second length in its setting direction.

[0122] In some embodiments, the circuit board 1043 has at least two layers in the portion laid along the axis. The two layers of the circuit board 1043 may be two layers formed by injection molding, or may be at least two layers formed by folding after the circuit board 1043 is manufactured; in this case, the portion of the circuit board 1043 arranged along the axial direction is folded into at least two layers.

[0123] In other embodiments, the circuit board 1043 provides a laying position for the transmission line through a substrate, and the thickness of the substrate can be made very small. On the one hand, it is convenient for axial spiral laying or undulating laying in the shaft module 103; on the other hand, when the number of the first connecting terminals 1041 and the second connecting terminals 1042 is large, the single-layer area of ​​the circuit board 1043 can be reduced by folding multiple layers.

[0124] For example, assuming that the connecting plate includes N first connecting terminals 1041 and N second connecting terminals 1042, if they are laid flat on a circuit board 1043, the circuit board 1043 may be relatively wide in the extension direction perpendicular to the connecting terminals. At this time, in order to reduce the width of the circuit board 1043, at least the main body 201 of the circuit board 1043 can be folded; thereby at least the width of the main body 201 is reduced.

[0125] In some embodiments, Figure 5A , Figure 5B and Figure 5C As shown, the shaft module 103 includes:

[0126] A first rotating shaft 1031 connected to the first body 101;

[0127] A second rotating shaft 1032 connected to the second body 102;

[0128] A linkage assembly 1033, connected to the first rotating shaft 1031 and the second rotating shaft 1032 respectively, for making the first rotating shaft 1031 and the second rotating shaft 1032 rotate synchronously;

[0129] A shaft sleeve 1034, sleeved on the outer sides of the first rotating shaft 1031 and the second rotating shaft 1032;

[0130] The circuit board 1043 is sequentially laid along the axial direction of the first rotating shaft 1031 , along the inner side of the sleeve 1034 in a direction perpendicular to the axial direction, and along the axial direction of the second rotating shaft 1032 .

[0131] In this embodiment, the rotating shaft module 103 is a double rotating shaft module 103 ; the first rotating shaft 1031 is connected to the first body 101 ; the second rotating shaft 1032 is arranged parallel to the first rotating shaft 1031 and connected to the second body 102 .

[0132] In this embodiment, the rotating shaft module 103 further includes a linkage assembly 1033 , which can synchronize the rotation between the first rotating shaft 1031 and the second rotating shaft 1032 .

[0133] For example, the linkage component 1033 includes:

[0134] A first meshing portion, fixedly connected to the first rotating shaft 1031 and rotating synchronously with the first rotating shaft 1031;

[0135] The second meshing portion is fixedly connected to the second rotating shaft 1032 and rotates synchronously with the second rotating shaft 1032 .

[0136] The first meshing portion and the second meshing portion may be meshed by straight teeth or helical teeth. Thus, if the first rotating shaft 1031 is a driving shaft, the first meshing portion rotates with the first rotating shaft 1031; the second meshing portion rotates based on the meshing with the first meshing portion, and drives the second rotating shaft 1032 to rotate. Of course, in a specific implementation, the driving shaft may also be the second rotating shaft 1032; the driven shaft may be the first rotating shaft 1031.

[0137] In this embodiment, the shaft module 103 also includes a sleeve 1034, which is sleeved on the outside of the first shaft 1031 and the second shaft 1032. On the one hand, it can protect the first shaft 1031 and the second shaft 1032 and buffer collisions. On the other hand, if the first shaft 1031 and the second shaft 1032 are relatively long and the linkage assembly 1033 is only provided at one or more specific positions, the sleeve 1034 also supports the two shafts, thereby reducing unnecessary deformation of the two shafts due to their own small supporting force.

[0138] In this embodiment, the circuit board 1043 is laid in the axial direction of the first rotating shaft 1031 and the second rotating shaft 1032. For example, the circuit board 1043 is spirally wound on the outside of the first rotating shaft 1031 and the second rotating shaft 1032; when crossing the two rotating shafts, it is laid along the direction of the sleeve 1034. In this way, the sleeve 1034 is used to hide and protect the circuit board 1043.

[0139] There are many structures of the shaft sleeve 1034, and two optional structures are provided below:

[0140] Option 1:

[0141] The shaft sleeve 1034 has a first through hole and a second through hole; wherein the first through hole is for the first rotating shaft 1031 to pass through; and the second through hole is for the second rotating shaft 1032 to pass through.

[0142] Option 2:

[0143] The shaft sleeve 1034 is an inverted U-shaped groove; the first rotating shaft 1031 and the second rotating shaft 1032 can pass through the two ends of the bottom of the groove.

[0144] like FIG. 4A to FIG. 4B As shown, this embodiment provides a connection module, including:

[0145] at least one first connecting terminal;

[0146] at least one second connecting terminal;

[0147] The circuit board is respectively connected to the at least one first connection terminal and the at least one second connection terminal, and is non-planarly arranged along a predetermined direction.

[0148] In some embodiments, the non-planar configuration includes but is not limited to the aforementioned bending configuration and / or curved configuration. FIG. 4A to FIG. 4C The main body of the circuit board shown is bent; Figure 4D The main body of the circuit board shown is arranged in a curved surface.

[0149] On the one hand, this non-planar setting can make full use of the space in the preset direction and increase the surface area of ​​the circuit board, so that more transmission lines and / or connecting terminals can be set up, and a large number of transmission lines and / or transmission terminals can be set up. On the other hand, this connection module has the characteristics of small size and high wiring density per unit area compared to the soft wire.

[0150] In some embodiments, Figure 4A , Figure 4B and Figure 4C The circuit board has a redundant structure capable of being stretched along a predetermined direction;

[0151] Wherein, when the connecting module is in the first state, the redundant structure is stretched in the predetermined direction, and the connecting module has a first length along the setting direction of the connecting module;

[0152] When the connecting module is in the second state, the redundant structure is not stretched in the predetermined direction, and the connecting module has a second length along the setting direction of the connecting module;

[0153] Wherein, the first length is greater than the second length.

[0154] The setting direction here refers to the overall arrangement direction of the main body, the first end and the second end of the circuit board.

[0155] The setting of the redundant structure can make the length of the connection module in the setting direction retractable, so that when the first body and the second body that are electrically connected by the connection module are rotated, the redundant structure of the connection module can provide the length required for rotational pulling, thereby reducing the pulling and wear caused by the relative movement of the first body and the second body at a fixed length, extending the service life of the connection module; reducing the stability of the electrical connection of the electronic device that uses the connection module to electrically connect the first body and the second body.

[0156] Furthermore, the redundant structure includes: the main body of the circuit board is spiral along the predetermined direction. Figure 4B The main board portion of the circuit board shown is in a spiral state; the extension direction of the multiple spiral turns is consistent, which is the predetermined direction.

[0157] In some other embodiments, the redundant structure includes:

[0158] The main body of the circuit board is undulating along a direction perpendicular to the predetermined direction; Figure 4A shown.

[0159] In short, reference FIG. 4A to FIG. 4C As shown, the first end 202 of the circuit board is provided with the at least one first connecting terminal; the second end 203 of the circuit board is provided with the at least one second connecting terminal; the first end 202 and the second end 203 are located at opposite ends of the main body of the circuit board.

[0160] In some other embodiments, reference may be made to Figure 4C As shown, the redundant structure is located at the first end and the second end, rather than on the main body of the circuit board.

[0161] The connection module provided in this embodiment is a plate-like wire material including a substrate, which is different from a flexible wire. The circuit board is used to provide transmission lines and connection terminals, which can reduce the space volume required for electrical connection compared to the flexible wire.

[0162] At the same time, the circuit board provided in this embodiment is also provided with a redundant structure, which can provide the additional length generated by pulling when the two bodies electrically connected by the connection module rotate relative to each other, thereby realizing a stable electrical connection between the two bodies.
