Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic devices, and in particular to a foldable electronic device. Background Art

[0002] With the development of science and technology, various foldable electronic devices have gradually become an indispensable part of life. Taking mobile phones as an example, in order to improve user experience and increase the functions of mobile phones, the display screens of mobile phones are getting bigger and bigger. In order to increase the display screen area of ​​mobile phones and reduce the size of mobile phones, foldable electronic devices have emerged.

[0003] In the current foldable electronic device, the display screen is supported by two main bodies, and the two main bodies are connected by rotation through a folding structure. The two main bodies can be relatively unfolded or folded to realize the unfolding and folding of the display screen. Among them, different circuit modules are respectively arranged in the two main bodies. In order to electrically connect and communicate between the two circuit modules in the two main bodies, a flexible printed circuit (FPC) is arranged in the current foldable electronic device, and the two circuit modules are electrically connected through the flexible printed circuit.

[0004] However, in current foldable electronic devices, when a problem occurs with the flexible circuit board and needs to be repaired, since the through-axis portion of the flexible circuit board is connected to the base of the rotating mechanism, when the flexible circuit board is removed from the foldable electronic device, the entire base needs to be removed together, which makes disassembly very difficult. In addition, the base is easily damaged during removal, resulting in increased repair costs. Utility Model Content

[0005] The present application provides a foldable electronic device, which reduces the difficulty of disassembling a flexible circuit board to reduce maintenance costs.

[0006] The present application provides a foldable electronic device, comprising: a first body, a second body, a rotating mechanism and a flexible circuit board, wherein the rotating mechanism is connected between the first body and the second body, and the rotating mechanism can make the first body and the second body relatively unfolded or relatively folded.

[0007] The first body may specifically include a first housing and a first functional module, the first functional module is disposed inside the first housing and may include components such as a first circuit board and a processor. The second body may specifically include a second housing and a second functional module, the second functional module is disposed inside the second housing and may include components such as a second circuit board and a sensor.

[0008] The relative expansion or folding of the first body and the second body actually refers to the relative expansion or folding of the first shell and the second shell. When the first shell and the second shell are relatively expanded, the first shell and the second shell are arranged in sequence along the width direction of the foldable electronic device, and the angle between them is 180 degrees. The rotating mechanism is blocked by the first shell and the second shell. The first shell and the second shell are stacked and arranged along the thickness direction of the foldable electronic device, and the angle between them is 0 degrees.

[0009] The flexible circuit board is arranged in the first body, the rotating mechanism and the second body to electrically connect the first body and the second body. Specifically, the flexible circuit board may include a first flexible segment, a through-shaft segment and a second flexible segment connected in sequence. The first flexible segment is arranged in the interior of the first shell and is electrically connected to the first circuit board. The second flexible segment is arranged in the interior of the second shell and is electrically connected to the second circuit board. The through-shaft segment is arranged in the rotating mechanism to realize that the first circuit board and the second circuit board are electrically connected in sequence through the first flexible segment, the through-shaft segment and the second flexible segment, so that the processor on the first circuit board can communicate with devices such as sensors on the second circuit board.

[0010] The rotating mechanism includes a support seat and a support plate, and the support seat and the support plate are stacked along the thickness direction of the foldable electronic device. The support seat includes a first base and a second base, and the first base and the second base are arranged along the length direction of the support plate. The first base and the second base are separately arranged, and the first base is detachably fixed to the support plate. There is a first interval between the first base and the support plate, and a part of the flexible circuit board is located in the first interval, that is, the through-shaft section is located in the first interval. The second base is fixed to the support plate.

[0011] In this application, when the flexible circuit board has a problem and needs to be repaired, the shaft cover is first opened, and then the first base is removed from the support plate, without separating the second base from the support plate. At this time, the flexible circuit board can be removed from the mobile phone together with the first base. It can be seen that in this embodiment, when removing the flexible circuit board, only the first base needs to be separated from the support plate, and the second base does not need to be removed. In this way, the flexible circuit board can be quickly removed from the mobile phone, and the second base can be prevented from being damaged, thereby reducing the maintenance cost.

[0012] In some embodiments, a first connecting member is provided at one end of the first base facing the second base. The first connecting member is provided with a first connecting hole, and the first connecting hole penetrates the first connecting member along the thickness direction of the first connecting member. A first matching hole is provided on the side of the support plate facing the first base, and the first connecting hole and the first matching hole are coaxial. The foldable electronic device also includes a first fastener, which is provided in the first connecting hole and the first matching hole, so that the first base can be detachably fixed to the support plate. The first fastener is used to connect the first base and the support plate, which has a simple structure and is easy to operate.

[0013] In some embodiments, a first extension piece is protruding from a surface of one side of the support plate facing the first connecting piece, one end of the first extension piece is fixed to the support plate, and the other end of the first extension piece faces the first connecting piece. The first matching hole is provided on the first extension piece. By providing the first extension piece and providing the first matching hole on the first extension piece, the depth of the first matching hole along the Z-axis direction can be increased, thereby making the first fastener and the first matching hole have more matching parts to increase the connection stability. In addition, the first extension piece is closer to the first connecting piece, and the length of the screw of the first fastener can match the first extension piece, and does not need to be set too long, which can avoid structural instability caused by the first fastener being too long.

[0014] In some embodiments, the first base is provided with first connecting members at both ends along the length direction of the foldable electronic device, and the two first connecting members are arranged in a staggered manner along the width direction of the foldable electronic device. That is, the two first fasteners are located at two diagonal positions of the first base, and the two first fasteners constitute two supporting points of the first base. The line connecting the two supporting points intersects with the central axis of the first base along the Y-axis direction, which can prevent the first base from shaking around its central axis in the Y-axis direction, thereby increasing the stability of the first base.

[0015] In some embodiments, there are two second bases, and along the length direction of the foldable electronic device, the first base is located between the two second bases. The two second bases are both provided with a second connecting member at one end facing the first base.

[0016] The first connector and the second connector are arranged along the width direction of the foldable electronic device, the first connector is provided with a first support portion on a side facing the second connector, and the second connector is provided with a second support portion on a side facing the first connector. In the thickness direction, the first support portion and the second support portion are stacked and in contact, and the first support portion is located on a side of the second support portion that is away from the support plate.

[0017] As can be seen from the above, both ends of the first base are provided with a first connecting member, and the two first connecting members are provided with a first supporting portion. The two second bases are provided with a second connecting member, and the two second connecting members are provided with a second supporting portion. In the process of assembling the rotating mechanism, after the second base is placed on the support plate, the first base is placed between the two second bases, so that the two first supporting portions are respectively stacked and contact the two second supporting portions, which can play a role in supporting the first base, thereby facilitating the assembly of the first fastener.

[0018] In addition, the two first support parts are stacked and in contact with the two second support parts respectively. The two first support parts are offset along the X-axis direction, and correspondingly, the two first support parts are also offset along the X-axis direction. The two first support parts constitute two supported points of the first base, and the line connecting the two supported points intersects with the central axis of the first base along the Y-axis direction. Therefore, before assembling the first fastener, the first support part and the second support part are stacked and in contact, which can prevent the first base from rotating around its central axis in the Y-axis direction, increase the stability of the first base, and reduce the difficulty of assembling the rotating mechanism.

[0019] In addition, the two first supporting parts are respectively stacked and contacted with the two second supporting parts, so as to increase the supported points of the second base and prevent the second base from rotating around its central axis in the Y-axis direction.

[0020] In some embodiments, a support column is provided between the support plate and the first connecting member, and opposite ends of the support column are fixed to the support plate and the first connecting member, respectively. The support column and the first supporting portion are respectively located on both sides of the first connecting hole along the width direction of the first supporting portion. Thus, before assembling the first fastener, the first base has the first supporting portion and the support column as supported points, and the first supporting portion and the support column are arranged at intervals along the X-axis direction. At this time, the supported points of the first base are increased, which can also be understood as that before the first fastener is assembled, the first supporting portion and the support column pre-position the first base to reduce the risk of the first base rotating around its central axis in the Y-axis direction. After the first fastener is assembled, the support column and the first supporting portion can continue to prevent the first base from rotating around the central axis in the Y-axis direction, so that the structural strength of the rotating mechanism is better.

[0021] In some embodiments, a first avoidance groove is recessed on the surface of the first connecting member facing the support plate, and along the thickness direction of the foldable electronic device, the first avoidance groove and the first matching hole are opposite, and the first connecting hole passes through the bottom surface of the first avoidance groove and the side surface of the first connecting member facing away from the support plate. The first extension member extends into the first avoidance groove toward one end of the first connecting member, and there is a gap between the first extension member and the bottom surface of the first avoidance groove.

[0022] It can be understood that if the first extension member and the bottom surface of the first avoidance groove contact each other to form another supported point, each first connecting member has three supported points arranged in sequence along the X-axis direction. If any of the three supported points is not on the same plane as the other two supported points, the first base will shake. It is difficult to control the three supported points to be located on the same plane. Therefore, if the first extension member and the bottom surface of the first avoidance groove are set to contact each other, the risk of the first base shaking around its central axis in the Y-axis direction will increase.

[0023] In this embodiment, a gap is provided between the first extension member and the bottom surface of the first avoidance groove, so that each first connecting member has two supported points arranged in sequence along the X-axis direction. The difficulty of controlling the two supported points to be located in the same plane is significantly lower than the difficulty of controlling the three supported points to be located in the same plane, thereby reducing the risk of the first base shaking around its central axis along the Y-axis direction.

[0024] In some other embodiments, the first avoidance groove is not provided on the surface of the first connecting member facing the support plate. In this case, along the thickness direction of the foldable electronic device, there is a gap between the first extending member and the surface of the first connecting member facing the support plate.

[0025] In some embodiments, the first base is provided with a first positioning portion, and the second base is provided with a second positioning portion, and the first positioning portion and the second positioning portion are in contact with each other, so that before the first fastener is assembled, the first base is pre-positioned so that the first connecting hole and the first matching hole are coaxial, thereby facilitating the assembly of the first fastener. After the first fastener is assembled, the first positioning portion and the second positioning portion remain in contact with each other, which can increase the stability of the first base and the second base.

[0026] In some embodiments, a first positioning surface is provided at one end of the first connector facing the second base, and a first mating surface is provided at one end of the second base facing the first connector, and the first positioning surface and the first mating surface are both parallel to the width direction of the foldable electronic device. Along the length direction of the foldable electronic device, the first positioning surface and the first mating surface abut each other. The first positioning portion includes a first positioning surface, and the second positioning portion includes a first mating surface. Thus, the first positioning surfaces of the two first connectors abut against the first mating surfaces of the two second bases, respectively, to limit the displacement of the first base along the Y-axis direction, thereby preventing the central axis of the first connecting hole and the central axis of the first mating hole from being misaligned along the Y-axis direction, and increasing the stability of the first base before assembling the first fastener. Of course, after the first fastener is assembled, the first positioning surface and the first mating surface continue to maintain an abutting state, increasing the stability of the first base. At the same time, according to the principle that the action of force is mutual, that is, while the first mating surface applies a holding force to the first positioning surface, the first positioning surface also applies a holding force to the first mating surface. Therefore, the first positioning surface and the first mating surface abut against each other, and the stability of the second base is also increased.

[0027] In some embodiments, a second positioning surface is provided on a side of the first connector facing the second connector, and a second mating surface is provided on a side of the second connector facing the first connector, and the second positioning surface and the second mating surface are both parallel to the length direction of the foldable electronic device. Along the width direction of the foldable electronic device, the second positioning surface and the second mating surface abut against each other. The first positioning portion includes the second positioning surface, and the second positioning portion includes the second mating surface.

[0028] Thus, the second positioning surfaces of the two first connecting members are respectively in contact with the two second matching surfaces of the two second connecting members, which can limit the movement of the first base along the X-axis direction, thereby preventing the central axis of the first connecting hole and the central axis of the first matching hole from being misaligned along the Y-axis direction, thereby increasing the stability of the first base before assembling the first fastener. In addition, after the first fastener is assembled, the second matching surface and the second positioning surface are in contact, which can continuously keep the first base stable, and at the same time, increase the stability of the second base.

[0029] In addition, if the first positioning surface and the first mating surface are not in contact, and the second positioning surface and the second mating surface are not in contact, the first base may also rotate around its central axis in the Z-axis direction. By setting two first positioning surfaces to abut against two first mating surfaces, and / or two second positioning surfaces to abut against two second mating surfaces, the first base can be restricted from rotating around its central axis in the Z-axis direction.

[0030] In some embodiments, a third positioning surface is provided at one end of the first base facing the second connector, and a third mating surface is provided at one end of the second connector facing the first base, and the third positioning surface and the third mating surface are both parallel to the width direction of the foldable electronic device. Along the length direction of the foldable electronic device, the third positioning surface and the third mating surface abut against each other. The first positioning portion includes the third positioning surface, and the second positioning portion includes the third mating surface.

[0031] Thus, before assembling the first fastener, the two third positioning surfaces at both ends of the first base are respectively in contact with the third matching surfaces of the two second connectors, so as to further limit the displacement of the first base along the Y-axis direction and prevent the central axis of the first connecting hole and the central axis of the first matching hole from being misaligned along the Y-axis direction. This further increases the stability of the first base before assembling the first fastener. In addition, after the first fastener is assembled, the third matching surface and the third positioning surface are in contact, which can continuously keep the first base stable and at the same time increase the stability of the second base.

[0032] In some embodiments, the first connecting member is provided with a positioning hole, a positioning column is provided on a side of the support plate facing the first connecting member, the first positioning portion includes the positioning hole, and the second positioning portion includes the positioning column. Alternatively, the support plate is provided with a positioning hole, and a positioning column is provided on a side of the first connecting member facing the support plate. The first positioning portion includes the positioning column, and the second positioning portion includes the positioning hole. A portion of the positioning column extends into the positioning hole. Thus, the first base can be further limited around its central axis along the Z-axis direction, thereby further increasing the stability of the first base before the first fastener is assembled.

[0033] In some embodiments, the foldable electronic device further includes a second fastener, and the second base is detachably connected to the support plate via the second fastener.

[0034] In some embodiments, the foldable electronic device further includes a third fastener, and the support plate is detachably connected to the shaft cover via the third fastener.

[0035] In some embodiments, along the thickness direction of the foldable electronic device, there is a second interval between the shaft cover and the first base, and the second interval is used to avoid the first fastener. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the first main body 210 and the second main body 220 facing away from the display screen 300 is the outer side of the electronic device, and the side carrying the display screen 300 is the inner side.

[0058] It should be noted that the directional terms such as “top”, “bottom”, “left”, “right”, “front” and “back” used in the embodiment of the present application to describe the foldable electronic device 1000 are mainly based on the foldable electronic device 1000 in the attached Figure 2 and Figure 5 The display orientation is explained in the figure, with the positive direction of the Z axis being the "top" and "upper", the negative direction of the Z axis being the "bottom" and "lower", the positive direction of the X axis being the "right", the negative direction of the X axis being the "left", the positive direction of the Y axis being the "back", and the negative direction of the Y axis being the "front".

[0068] The rotating mechanism 230 includes a support seat 100, a support plate 110, a shaft cover 120, a synchronization assembly (not shown), a damping assembly (not shown) and a swing arm assembly (not shown). The support seat 100, the support plate 110 and the shaft cover 120 are all in the shape of long strips, and the length directions of the support seat 100, the support plate 110 and the shaft cover 120 are all parallel to the Y-axis direction. Along the Y-axis direction, the lengths of the support seat 100, the support plate 110 and the shaft cover 120 are roughly the same. Along the Z-axis direction, the support plate 110, the support seat 100 and the shaft cover 120 are stacked in sequence. The support seat 100 and the support plate 110 are fixedly connected, and the support plate 110 and the shaft cover 120 are fixedly connected.

[0069] When the mobile phone is in a folded state, the shaft cover 120 is located in the receiving groove. When the mobile phone is in an unfolded state, the shaft cover 120 is exposed from the receiving groove. The shaft cover 120 is located between the first shell 240 and the second shell 270 and is an appearance part of the mobile phone. The support seat 100 is used to install the synchronization component, the damping component and the swing arm component. The support plate 110 is used to support the third display part 330 of the display screen 300.

[0070] In this embodiment, the support base 100 includes a first base 10 and two second bases 20. Along the Y-axis direction, the first base 10 is located between the two second bases 20, and the first base 10 and the two second bases 20 are separately arranged. The first base 10 and the support plate 110 are detachably fixedly connected. Along the Z-axis direction, there is a first interval 101 between the first base 10 and the support plate 110. The first interval 101 is used to accommodate the threading section 420 of the flexible circuit board 400 so that the flexible circuit board 400 can be threaded smoothly.

[0071] The length of the first base 10 along the Y-axis direction and the position of the first base 10 are determined according to the length and position of the through-axis section 420 of the flexible circuit board 400. When setting, the first base 10 and the through-axis section 420 are opposite to each other along the Z-axis direction, and the projection of the through-axis section 420 on the support base 100 is completely located on the first base 10.

[0072] In this embodiment, the support base 100 is divided into a first base 10 and a second base 20, and the first base 10 and the second base 20 are separately arranged, the first base 10 and the support plate 110 are detachably connected, the second base 20 can be detachably connected to the support plate 110, or the second base 20 and the support plate 110 are integrally formed and fixed.

[0073] When the flexible circuit board 400 has a problem and needs to be repaired, the shaft cover 120 is opened first, and then the first base 10 is removed from the support plate 110, without separating the second base 20 from the support plate 110. At this time, the flexible circuit board 400 can be removed from the mobile phone together with the first base 10. It can be seen that in this embodiment, when removing the flexible circuit board 400, it is only necessary to separate the first base 10 from the support plate 110, and the second base 20 does not need to be removed. In this way, the flexible circuit board 400 can be quickly removed from the mobile phone, and the second base 20 can be prevented from being damaged, thereby reducing the maintenance cost.

[0074] For some examples, please refer to Figure 7 , Figure 7 yes Figure 5Schematic diagram of the structure of the rotating mechanism 230 from another perspective is shown in . Along the Z-axis direction, the thickness of the two second bases 20 is equal, and the thickness of the second base 20 is greater than the thickness of the first base 10. When the support plate 110, the support base 100 and the shaft cover 120 are stacked in sequence along the Z-axis direction, the top surface of the second base 20 contacts the bottom surface of the support plate 110, and the bottom surface of the second base 20 contacts the top surface of the shaft cover 120. The first base 10 is located in the space enclosed by the support plate 110 and the two second bases 20, and because the thickness of the first base 10 is less than the thickness of the second base 20, the top surface of the first base 10 and the bottom surface of the support plate 110 may not contact each other to form a first interval 101, and the first interval 101 accommodates the through-shaft section 420 of the flexible circuit board 400, and the through-shaft section 420 is fixed in the first interval 101. Similarly, the bottom surface of the first base 10 and the top surface of the shaft cover 120 may not be in contact with each other to form the second gap 102 .

[0075] For some examples, please refer to Figure 7 and Figure 8 , Figure 8 yes Figure 5 , which is a structural schematic diagram of another perspective of the rotating mechanism 230. The first base 10 can be detachably connected to the support plate 110 through the first fastener 130. Specifically, there can be two first fasteners 130, and the two first fasteners 130 respectively connect the two sides of the first base 10 opposite to each other along the X-axis direction to the support plate 110. The first fastener 130 can be a screw or a bolt, etc. The first fastener 130 can include a nut and a screw, and the nut is fixed to the end of the screw. The above-mentioned second interval 102 can be used to accommodate the nut of the first fastener 130 to prevent the nut of the first fastener 130 from hitting the shaft cover 120, thereby preventing the shaft cover 120 from being damaged by the nut.

[0076] The second base 20 can be detachably connected to the support plate 110 through a second fastener 140, and the second fastener 140 can be a bolt or a screw, etc. The number of the second fasteners 140 can be three, wherein two second fasteners 140 are arranged on the side of the second base 20 away from the first base 10, and the two second bases 20 pass through the second base 20 and are fixed to the support plate 110, so that the side of the second base 20 away from the first base 10 is detachably connected to the support plate 110; another second fastener 140 connects the side of the second base 20 facing the first base 10 to the support plate 110. Figure 7 and Figure 8 The position of the second fastener 140 on the side of the second base 20 away from the first base 10 is only exemplary. In fact, the position of the second fastener 140 can be designed according to actual needs.

[0077] The support plate 110 can be detachably connected to the shaft cover 120 through the third fastener 150, and the third fastener 150 can be a bolt or a screw, etc. Specifically, the support plate 110 is detachably connected to the shaft cover 120 through the third fastener 150, and the third fastener 150 passes through the support plate 110, the support seat 100 and the shaft cover 120 in sequence, so that the support plate 110 and the shaft cover 120 are detachably connected. Figure 7 and Figure 8 The position of the third fastener 150 shown in FIG. 1 is only exemplary. In fact, the position of the third fastener 150 can be designed according to actual needs.

[0078] The assembly sequence of the first base 10, the second base 20, the support plate 110 and the shaft cover 120 is as follows: first, fix the two second bases 20 to the support plate 110 through the second fasteners 140, then fix the first base 10 to the support plate 110 through the first fasteners 130, and finally fix the support plate 110 to the shaft cover 120 through the third fasteners 150.

[0079] The specific implementation method of connecting the first base 10 and the support plate 110 through the first fastener 130 is described below:

[0080] For some examples, please refer to Fig. 9 and Fig.10 , Fig. 9 yes Figure 6 Schematic diagram of the split structure of part of the rotating mechanism 230. Fig.10 yes Fig. 9 A split schematic diagram of another perspective of the partial structure of the rotating mechanism 230 is shown in FIG. The support plate 110 is in the shape of a rectangular plate, and the top surface of the support plate 110 is used to support the third display part of the flexible display screen 300. The support plate 110 is provided with a first matching hole 112. The first matching hole 112 can be a threaded hole. Specifically, a first extension member 111 is convexly provided on the bottom surface of the support plate 110, and the axial direction of the first extension member 111 is parallel to the Z-axis direction, and one end of the first extension member 111 is fixed to the bottom surface of the support plate 110, and the other end of the first extension member 111 extends in a direction away from the bottom surface of the support plate 110. The first matching hole 112 is provided in the first extension member 111. Specifically, the first matching hole 112 can be recessed at one end of the first extension member 111 away from the bottom surface of the support plate 110, or the first matching hole 112 passes through the first extension member 111 along the Z-axis direction.

[0081] The first base 10 is roughly in the shape of a rectangular plate, and the first connecting member 11 is fixed to the front and rear surfaces of the first base 10. The first connecting member 11 is provided with a first connecting hole 12, and the first connecting hole 12 penetrates the first connecting member 11 along the Z-axis direction. That is, the first connecting hole 12 penetrates the top surface and the bottom surface of the first connecting member 11, the top surface of the first connecting member 11 faces the first interval, and the bottom surface of the first connecting member 11 faces the second interval. The first connecting hole 12 can be a threaded hole.

[0082] Please refer to Fig.11 , Fig.11 yes Figure 5 The cross-sectional structure schematic diagram of the rotating mechanism 230 is shown in FIG. When the first base 10 and the support plate 110 are connected by the first fastener 130, the first base 10 and the support plate 110 are stacked along the Z-axis direction, and the first connecting hole 12 and the first matching hole 112 are coaxial. Then the screw of the first fastener 130 extends from the bottom surface of the first connecting member 11 into the first connecting hole 12, and the screw of the first fastener 130 enters the first matching hole 112 from the first connecting hole 12. The screw of the first fastener 130 can be threadedly matched with the first connecting hole 12, the screw of the first fastener 130 is threadedly connected with the first matching hole 112, and the nut of the first fastener 130 can abut against the bottom surface of the first connecting member 11, thereby realizing the detachable connection between the first base 10 and the support plate 110. After the shaft cover 120 is assembled to the rotating mechanism 230, the nut of the first fastener 130 is located in the above-mentioned second interval 102. In other embodiments, the first matching hole 112 may be set as a light hole, and the screw of the first fastener 130 is clearance-matched with the first matching hole 112. It can be seen that the first fastener 130 is used to connect the first base 10 and the support plate 110, which has a simple structure and is easy to operate.

[0083] By providing the first extension piece 111 and providing the first matching hole 112 on the first extension piece 111, the depth of the first matching hole 112 along the Z-axis direction can be increased, thereby increasing the matching positions of the first fastener 130 and the first matching hole 112 to increase the connection stability. In addition, the first extension piece 111 is closer to the first connecting piece 11, and the length of the screw of the first fastener 130 can match the first extension piece 111, and does not need to be set too long, which can avoid structural instability caused by the first fastener 130 being too long.

[0084] In other embodiments, the first extension piece 111 may not be provided, but the first matching hole 112 may be provided to penetrate the top surface and the bottom surface of the support plate 110 , or the first matching hole 112 may be provided to be recessed in the bottom surface of the support plate 110 .

[0085] For some embodiments, please continue to refer to Fig. 9 and Fig.11, a first avoidance groove 13 is recessed on the top surface of the first connecting member 11, and the first connecting hole 12 passes through the bottom surface of the first avoidance groove 13 and the bottom surface of the first connecting member 11. The first avoidance groove 13 is coaxial with the first connecting hole 12. A portion of the first extension member 111 extends into the first avoidance groove 13. On the one hand, the first avoidance groove 13 can provide space for the first extension member 111, so that the first extension member 111 can be set longer, and then the depth of the first matching hole 112 can be further increased, and the length of the matching part between the first extension member 111 and the screw of the first fastener 130 can be increased. In some other embodiments, the first extension member 111 can also directly contact the bottom surface of the first avoidance groove 13. In some other embodiments, the first avoidance groove 13 may not be provided, and in this case, a gap can be provided between the first extension member 111 and the top surface of the first connecting member 11.

[0086] Those skilled in the art will appreciate that if the first base 10 has a support point at each of the two opposite ends along the length direction, and the line connecting the two support points is parallel to the central axis of the first base 10 along the Y-axis direction, it will easily cause the first base 10 to rotate around the central axis along the Y-axis direction.

[0087] In order to solve the above problems, in some embodiments, the two first connecting members 11 at both ends of the first base 10 are staggered along the X-axis direction, and therefore the two first fasteners 130 connecting the first base 10 and the support plate 110 are also staggered along the X-axis direction. Specifically, the two first fasteners 130 are located at two diagonal positions of the first base 10, and the two first fasteners 130 constitute two supporting points of the first base 10. The line connecting the two supporting points intersects with the central axis of the first base 10 along the Y-axis direction, which can prevent the first base 10 from shaking around its central axis in the Y-axis direction, thereby increasing the stability of the first base 10.

[0088] For some embodiments, please continue to refer to Fig. 9 , Fig.10 and Fig.11, the two second bases 20 are provided with a second connecting member 21 at one end facing the first base 10. The second base 20 is detachably fixed by the second connecting member 21 and a second fastener 140 on the side facing the first base 10. A second extension member 113 may also be provided on the bottom surface of the support plate 110, and the structure of the second extension member 113 and the matching relationship with other parts refer to the first extension member 111. The second connecting member 21 is provided with a second connecting hole 22, and the second extending member 113 is provided with a second matching hole 114. A second avoidance groove 23 is recessed on the top surface of the second connecting member 21. The way in which the second base 20 is detachably fixed by the second connecting member 21 and another second fastener 140 can refer to the way in which the first base 10 is detachably fixed by the first connecting member 11 and the first fastener 130. The structure and function of the second connecting hole 22, the second matching hole 114 and the second avoidance groove 23 can refer to the first connecting hole 12, the first matching hole 112 and the first avoidance groove 13, and will not be repeated.

[0089] For some examples, please refer to Fig. 9 and Fig.10 , the first connecting member 11 and the second connecting member 21 are arranged along the X-axis direction, and the first supporting portion 14 is provided on the side of the first connecting member 11 facing the second connecting member 21. Along the Z-axis direction, the thickness of the first supporting portion 14 is less than the thickness of the first connecting member 11, the first supporting portion 14 and the first connecting member 11 are distributed in a step-like manner, the top surface of the first supporting portion 14 and the top surface of the first connecting member 11 have a height difference, and the bottom surface of the first supporting portion 14 and the bottom surface of the first connecting member 11 are flush or have a height difference.

[0090] A second supporting portion 24 is provided on one side of the second connecting member 21 facing the first connecting member 11. Along the Z-axis direction, the thickness of the second connecting member 21 is substantially the same as that of the first connecting member 11, and the thickness of the second supporting portion 24 is less than that of the second connecting member 21. The second supporting portion 24 and the second connecting member 21 are distributed in a stepped manner, the top surface of the second supporting portion 24 is flush with the top surface of the second connecting member 21 or has a height difference, and the bottom surface of the second supporting portion 24 and the bottom surface of the second connecting member 21 have a height difference.

[0091] Please refer to Fig.12 , Fig.12 yes Figure 5A schematic cross-sectional view of a partial structure of the rotating mechanism 230 shown in FIG. Along the Z-axis direction, the first support portion 14 and the second support portion 24 are stacked and in contact, and the first support portion 14 is located on the side of the second support portion 24 away from the support plate 110. Specifically, the top surface of the first support portion 14 and the bottom surface of the second support portion 24 are in contact. And the sum of the thicknesses of the first support portion 14 and the second support portion 24 is substantially the same as that of the first connecting member 11, and the thicknesses of the first connecting member 11 and the second connecting member 21 are the same, so after the first support portion 14 and the second support portion 24 are stacked, the top surface of the first connecting member 11 and the top surface of the second connecting member 21 are substantially flush, and the bottom surface of the first connecting member 11 and the bottom surface of the second connecting member 21 are substantially flush. Part of the side surface of the first connecting member 11 and the side surface of the second connecting member 21 can be in direct contact to increase the stability of the first base 10. It can be understood that the side surface of the first connecting member 11 is the surface between the top surface and the bottom surface of the first connecting member 11, and the side surface of the second connecting member 21 is the surface between the top surface and the bottom surface of the second connecting member 21.

[0092] As can be seen from the above, both ends of the first base 10 are provided with a first connecting member 11, and the two first connecting members 11 are provided with a first supporting portion 14. The two second bases 20 are provided with a second connecting member 21, and the two second connecting members 21 are provided with a second supporting portion 24. In the process of assembling the rotating mechanism 230, after the second base 20 is placed on the support plate 110, the first base 10 is placed between the two second bases 20, so that the two first supporting portions 14 are respectively stacked and contact the two second supporting portions 24, which can play a role in supporting the first base 10, thereby facilitating the assembly of the first fastener 130.

[0093] In addition, the two first support parts 14 are stacked and contacted with the two second support parts 24 respectively. The two first support parts 14 are misaligned along the X-axis direction, and correspondingly, the two first support parts 14 are also misaligned along the X-axis direction. The two first support parts 14 constitute two supported points of the first base 10, and the supported point here refers to the center point of the portion where the first support part 14 and the second support part 24 are stacked. The line connecting the two supported points intersects with the center axis of the first base 10 along the Y-axis direction. Therefore, before assembling the first fastener 130, the first support part 14 and the second support part 24 are stacked and contacted, which can prevent the first base 10 from rotating around its center axis in the Y-axis direction, increase the stability of the first base 10, and reduce the difficulty of assembling the rotating mechanism 230. After the first fastener 130 is assembled, the first support part 14 and the second support part 24 remain in a stacked state to maintain the stability of the first base 10.

[0094] In addition, the two first support portions 14 are respectively stacked and contacted with the two second support portions 24, which can also increase the stability of the second base 20. Specifically, before the first support portion 14 and the second support portion 24 are stacked, the second base 20 is fixed to the support plate 110 by three second fasteners 140, that is, the second base 20 has three support points. After the first support portion 14 and the second support portion 24 are stacked, the second base 20 has four support points, and the four support points are basically distributed in a trapezoidal shape. Compared with three supports, the second base 20 is more stable, reducing the risk of the second base 20 shaking around its central axis in the Y-axis direction.

[0095] In some embodiments, please also refer to Fig. 9 , Fig.10 and Fig.12 , a support column 160 is provided between the support plate 110 and the first connecting member 11, and opposite ends of the support column 160 are respectively fixed to the support plate 110 and the first connecting member 11; the support column 160 and the first supporting portion 14 are respectively located on both sides of the first connecting hole 12 along the width direction of the first supporting portion 14. In one specific embodiment, one end of the support column 160 is fixed to the bottom surface of the support plate 110, and the other end of the support column 160 abuts against the top surface of the first connecting member 11, that is, the support column 160 is protruded from the bottom surface of the support plate 110. In another specific embodiment, one end of the support column 160 is fixed to the top surface of the first connecting member 11, and the other end of the support column 160 abuts against the top surface of the support plate 110, that is, the support column 160 is protruded from the top surface of the first connecting member 11. In another embodiment, the support column 160 includes a first support section and a second support section, the first support section is protruding from the bottom surface of the support plate 110, and the second support section is protruding from the top surface of the first connecting member 11, and the end of the first support section away from the bottom surface of the support plate 110 abuts against the end of the second support section away from the top surface of the first connecting member 11.

[0096] Thus, before assembling the first fastener 130, the first base 10 has a plurality of supported points formed by the first support portion 14 and the support column 160, and the support point formed by the support column 160 refers to the center point of the portion where the first base 10 and the support column 160 contact. And the first support portion 14 and the support column 160 are arranged at intervals along the X-axis direction. At this time, the number of supported points of the first base 10 increases, which can further reduce the risk of the first base 10 rotating around its central axis in the Y-axis direction. It can also be understood that before the first fastener 130 is assembled, the first support portion 14 and the support column 160 pre-position the first base 10. After the first fastener 130 is assembled, the support column 160 and the first support portion 14 can continue to prevent the first base 10 from rotating around the central axis in the Y-axis direction, so that the structural strength of the rotating mechanism 230 is better.

[0097] In some embodiments, each first connecting member 11 corresponds to two supporting columns 160, the two supporting columns 160 are arranged at intervals along the Y-axis direction, and the line connecting the central axes of the two supporting columns 160 along the Y-axis direction is parallel to the Y-axis. Thus, each first connecting member 11 has a first supporting portion 14 and two supporting columns 160, a total of three supported points, and the connecting lines between the three supported points form a triangle, so that both ends of the first base 10 can be stably supported, further reducing the risk of the first base 10 rotating around its central axis in the Y-axis direction.

[0098] As can be seen from the above, before assembling the first fastener 130, there are three supported points, namely, a first support portion 14 and two support columns 160, between each first connecting member 11 and the support plate 110. It can be understood that the three supported points pre-position the first base 10 before assembling the first fastener 130. In addition, along the X-axis direction, there is a gap between the first extension member 111 located between the first support portion 14 and the support column 160 and the bottom surface of the first avoidance groove 13, and there is a gap K between the first extension member 111 and the bottom surface of the first avoidance groove 13.

[0099] It can be understood that if the first extension member 111 and the bottom surface of the first avoidance groove 13 contact each other to form another supported point, each first connecting member 11 has three supported points arranged in sequence along the X-axis direction, and the three supported points are the first supporting portion 14, the first extension member 111 and the support column 160. If any of the three supported points is not on the same plane as the other two supported points, it will cause the first base 10 to shake. It is difficult to control the three supported points to be located in the same plane. Therefore, if the first extension member 111 is set to contact the bottom surface of the first avoidance groove 13, the risk of the first base 10 shaking around its central axis in the Y-axis direction will increase.

[0100] In this embodiment, a gap is provided between the first extension member 111 and the bottom surface of the first avoidance groove 13, so that each first connecting member 11 has two supported points arranged in sequence along the X-axis direction. The difficulty of controlling the two supported points to be located in the same plane is significantly lower than the difficulty of controlling the three supported points to be located in the same plane, thereby reducing the risk of the first base 10 shaking around its central axis along the Y-axis direction.

[0101] For some examples, please refer to Fig.13 and Fig.14 , Fig.13 yes Figure 5 A schematic diagram of another part of the structure of the rotating mechanism 230 is shown in FIG. Fig.14 yes Figure 5, a partial structural diagram of the rotating mechanism 230 is shown in FIG. The first base 10 is provided with a first positioning portion 15, and the second base 20 is provided with a second positioning portion 25. The first positioning portion 15 and the second positioning portion 25 are in contact with each other, so that the first base 10 is pre-positioned before the first fastener 130 is assembled, so that the first connecting hole 12 and the first matching hole 112 are coaxial, thereby facilitating the installation of the first fastener 130 and increasing the assembly efficiency and assembly accuracy. After the first fastener 130 is assembled, the first positioning portion 15 and the second positioning portion 25 remain in contact with each other, which can increase the stability of the first base 10 and the second base 20.

[0102] For some embodiments, please continue to refer to Fig.13 and Fig.14 , a first positioning surface 16 is provided at one end of the first connecting member 11 facing the second base 20, and a first mating surface 26 is provided at one end of the second base 20 facing the first connecting member 11, and the first positioning surface 16 and the first mating surface 26 are both parallel to the X-axis direction. Along the Y-axis direction, the first positioning surface 16 and the first mating surface 26 abut. The first positioning portion 15 includes the first positioning surface 16, and the second positioning portion 25 includes the first mating surface 26. Thus, the first positioning surfaces 16 of the two first connecting members 11 abut against the first mating surfaces 26 of the two second bases 20, respectively, limiting the displacement of the first base 10 along the Y-axis direction, thereby preventing the central axis of the first connecting hole 12 and the central axis of the first mating hole 112 from being misaligned along the Y-axis direction, and increasing the stability of the first base 10 before assembling the first fastener 130. Of course, after the first fastener 130 is assembled, the first positioning surface 16 and the first mating surface 26 continue to maintain an abutment state, which increases the stability of the first base 10. At the same time, based on the principle that the action of force is mutual, that is, while the first mating surface 26 applies a holding force to the first positioning surface 16, the first positioning surface 16 also applies a holding force to the first mating surface 26. Therefore, the first positioning surface 16 and the first mating surface 26 abut against each other, which also increases the stability of the second base 20.

[0103] For some embodiments, please continue to refer to Fig.13 and Fig.14 The first connector 11 is provided with a second positioning surface 17 on one side facing the second connector 21, and the second connector 21 is provided with a second mating surface 27 on one side facing the first connector 11. The second positioning surface 17 and the second mating surface 27 are both parallel to the Y-axis direction. Along the X-axis direction, the second positioning surface 17 and the second mating surface 27 abut against each other. The first positioning portion 15 includes the second positioning surface 17, and the second positioning portion 25 includes the second mating surface 27.

[0104] Since the two first connecting members 11 are staggered in the X-axis direction, the two second connecting members 21 are also staggered in the X-axis direction. Therefore, one of the second positioning surfaces 17 and the second matching surface 27 are arranged and abutted in sequence from the positive direction of the X-axis to the negative direction of the X-axis to limit the first base 10 from moving in the positive direction of the X-axis. Another second positioning surface 17 and another second matching surface 27 are arranged and abutted in sequence from the negative direction of the X-axis to the positive direction of the X-axis to limit the first base 10 from moving in the negative direction of the X-axis. Thus, the second positioning surfaces 17 of the two first connecting members 11 are respectively abutted against the two second matching surfaces 27 of the two second connecting members 21, which can limit the movement of the first base 10 in the X-axis direction, thereby preventing the central axis of the first connecting hole 12 and the central axis of the first matching hole 112 from being misaligned in the Y-axis direction, thereby increasing the stability of the first base 10 before assembling the first fastener 130. In addition, after the first fastener 130 is assembled, the second mating surface 27 and the second positioning surface 17 abut against each other, which can continuously stabilize the first base 10 and increase the stability of the second base 20. The principle of increasing the stability of the second base 20 by the abutment of the second mating surface 27 and the second positioning surface 17 can refer to the principle of increasing the stability of the second base 20 by the abutment of the first mating surface 26 against the first positioning surface 16.

[0105] In addition, if the first positioning surface 16 and the first mating surface 26 are not in contact, and the second positioning surface 17 and the second mating surface 27 are not in contact, the first base 10 may also rotate around its central axis in the Z-axis direction. By setting the two first positioning surfaces 16 and the two first mating surfaces 26 to abut, and / or the two second positioning surfaces 17 and the two second mating surfaces 27 to abut, the first base 10 can be restricted from rotating around its central axis in the Z-axis direction.

[0106] For some embodiments, please continue to refer to Fig.13 and Fig.14 The first base 10 has a third positioning surface 18 at one end facing the second connector 21, and the second connector 21 has a third mating surface 28 at one end facing the first base 10. The third positioning surface 18 and the third mating surface 28 are both parallel to the X-axis direction. Along the Y-axis direction, the third positioning surface 18 and the third mating surface 28 abut against each other. The first positioning portion 15 includes the third positioning surface 18, and the second positioning portion 25 includes the third mating surface 28.

[0107] Therefore, before assembling the first fastener 130, the two third positioning surfaces 18 at both ends of the first base 10 are respectively abutted against the third matching surfaces 28 of the two second connecting members 21, so as to further limit the displacement of the first base 10 along the Y-axis direction and prevent the central axis of the first connecting hole 12 and the central axis of the first matching hole 112 from being misaligned along the Y-axis direction. Thus, the stability of the first base 10 before assembling the first fastener 130 is further increased. In addition, after the first fastener 130 is assembled, the third matching surface 28 abuts against the third positioning surface 18, which can continuously keep the first base 10 stable and at the same time, increase the stability of the second base 20. The principle of the third matching surface 28 abutting against the third positioning surface 18 to increase the stability of the second base 20 refers to the principle of the first matching surface 26 abutting against the first positioning surface 16 to increase the stability of the second base 20.

[0108] Specifically, the length dimension of the first connecting member 11 and the second connecting member 21 along the Y-axis direction is the same. When the first base 10 and the second base 20 are arranged in sequence along the Y-axis direction, the first connecting member 11 and the second connecting member 21 are arranged along the X-axis direction. At this time, the overall structure of the support base 100 can be made more compact. In addition, the end face of the first connecting member 11 away from the first base 10 and the end face of the second base 20 facing the first base 10 can be abutted, the side face of the first connecting member 11 facing the second connecting member 21 can be abutted with the side face of the second connecting member 21 facing the first connecting member 11, and the end face of the second connecting member 21 away from the second base 20 can be abutted with the end face of the first base 10 facing the second base 20. The end face of the first connecting member 11 away from the first base 10 is the first positioning surface 16, and the end face of the second base 20 facing the first base 10 is the first mating surface 26. The side of the first connecting member 11 facing the second connecting member 21 is the second positioning surface 17, and the side of the second connecting member 21 facing the first connecting member 11 is the second mating surface 27. The end surface of the first base 10 facing the second base 20 is the third positioning surface 18, and the end surface of the second connecting member 21 away from the second base 20 is the third mating surface 28.

[0109] For some embodiments, please continue to refer to Fig. 9 , Fig.10 and Fig.11, the first connecting member 11 is provided with a positioning hole 19, and a positioning column 115 is provided on the side of the support plate 110 facing the first connecting member 11. A part of the positioning column 115 extends into the positioning hole 19. The first positioning portion 15 includes the positioning hole 19, and the second positioning portion 25 includes the positioning column 115. As a result, the first base 10 can be further restricted around its central axis along the Z-axis direction, thereby further increasing the stability of the first base 10 before assembling the first fastener 130. Specifically, the first connecting member 11 extends a triangular extension block toward the second connecting member 21, and correspondingly, the second connecting member 21 forms a triangular avoidance space toward the first connecting member 11, and the extension block of the first connecting member 11 is located in the avoidance space of the second connecting member 21, so that the volume of the first connecting member 11 is increased, so that the first connecting member 11 has enough space to set the positioning hole 19, and the structure of the first connecting member 11 and the second connecting member 21 can also be made compact.

[0110] In other embodiments, the support plate 110 is provided with a positioning hole 19 , and a positioning column 115 is provided on the side of the first connecting member 11 facing the support plate 110 . Accordingly, the first positioning portion 15 includes the positioning column 115 , and the second positioning portion 25 includes the positioning hole 19 .

[0111] The above are only some embodiments and implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
