In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0053] See also Figure 1 to Figure 15The embodiment of the present application provides an electronic device, including a rotating shaft assembly 600, a heat conducting assembly 400 and a target component 330, wherein the rotating shaft assembly 600 has a first rotating shaft 610 and a second rotating shaft 620 respectively connected to a first body 100 and a second body 200 of the electronic device, the first rotating shaft 610 rotates around a first axis Z1, and the second rotating shaft 620 rotates around a second axis Z2. The heat conducting assembly 400 has a first heat conducting member 410 and a second heat conducting member 420 respectively connected to the first body 100 and the second body 200, and the target component 330 has a first connecting portion and a second connecting portion that can conduct heat to each other, that is, the first connecting portion and the second connecting portion are components of the target component 330, and heat can be conducted between the first connecting portion and the second connecting portion, for example, at least a portion of the target component 330 between the first connecting portion and the second connecting portion can be a heat conducting path made of a heat conducting material, and the heat conducting path can be integrated with the first connecting portion and the second connecting portion, so that the first connecting portion and the second connecting portion can conduct heat to each other. The first connection portion is rotationally connected to the first heat conducting member 410 , and the rotation axis satisfies the collinear condition with the first axis Z1 ; the second connection portion is rotationally connected to the second heat conducting member 420 , and the rotation axis satisfies the collinear condition with the second axis Z2 .

[0054] The first body 100 and the second body 200 of the electronic device are connected by the hinge assembly 600, and can realize relative rotation, that is, the first body 100 and the second body 200 can realize opening and closing movement. The electronic device can be various types such as a laptop computer, a folding mobile phone, etc. The first body 100 and the second body 200 are two parts of the electronic device that have relative rotation requirements. Taking a laptop computer as an example, the first body 100 can be the system end, and the second body 200 can be the screen end. The hinge assembly 600 has a first hinge 610 and a second hinge 620, which rotate around a first axis Z1 and a second axis Z2 respectively, that is, the first hinge 610 rotates around the first axis Z1 to provide a rotation function for the first body 100 and the second body 200, and the second hinge 620 rotates around the second axis Z2 to provide a rotation function for the first body 100 and the second body 200. It can also be said that the hinge assembly 600 can be understood as at least including a dual-axis hinge structure.

[0055] The first heat-conducting member 410 of the heat-conducting assembly 400 is connected to the first body 100, and heat can be transferred from the first body 100 to other locations, such as the second body 200, the protective shell of the electronic device, etc., or vice versa, heat can be transferred from other locations to the first body 100. The second heat-conducting member 420 of the heat-conducting assembly 400 is connected to the second body 200, and heat can be transferred from the second body 200 to other locations, such as the first body 100, the protective shell of the electronic device, etc., or vice versa, heat can be transferred from other locations to the second body 200. In an embodiment in which the first heat conductive member 410 and the second heat conductive member 420 are connected to the first body 100 and the second body 200 respectively, the first heat conductive member 410 and the second heat conductive member 420 are connected through the target component 330, wherein the first heat conductive member 410 is rotatably connected to the first connecting portion of the target component 330, and the second heat conductive member 420 is rotatably connected to the second connecting portion of the target component 330. Under the connection effect of the target component 330, the first heat conductive member 410 and the second heat conductive member 420 can still be well maintained after the first body 100 and the second body 200 of the electronic device are opened and closed multiple times. Rotate concentrically with the shaft assembly 600, that is, the target component 330 makes the rotation center line of the first heat conductor 410 rotating with the first body 100 and the rotation center line of the first shaft 610 rotating with the first body 100 meet the colinear condition, and the colinear condition means that the two lines coincide with each other as one line, and makes the rotation center line of the second heat conductor 420 rotating with the second body 200 and the rotation center line of the second shaft 620 rotating with the second body 200 meet the colinear condition, thus reducing the influence of the heat conductive component 400 on the normal operation of the shaft assembly 600 with a dual rotation axis.

[0056] One of the functions of the thermal conductive component 400 in an electronic device is to transfer heat from a high temperature area to a low temperature area, thereby achieving a heat dissipation function. The thermal conductive component 400 can be configured to transfer heat from the first body 100 to the second body 200, or it can be configured to transfer heat from the second body 200 to the first body 100, or it can be configured to transfer heat from the first body 100 and the second body 200 to a target area, and the target area has better heat dissipation conditions relative to the heat source, for example, the target area has more heat dissipation area, or the thermal conductive component 400 is arranged from the heat source to the target area to provide more heat dissipation area, etc. This application does not limit the configuration of the thermal conductive component 400. Figure 2 and Figure 3In the exemplary embodiment, the first body 100 may include a target heat generating component 101, which may be, for example, a chip on a motherboard. The target heat generating component 101 may be heat-transferably connected to the first heat conducting member 410, and the heat conducting assembly 400 may transfer the heat generated by the target heat generating component 101 to the second body 200, thereby achieving heat dissipation of the target heat generating component 101. Figure 2 As shown, in some embodiments, the second body 200 may include a heat sink 201, and the heat sink 201 may be connected to the second heat conductor 420 for heat transfer, and the heat sink 201 provides a larger heat dissipation area for heat dissipation, thereby improving the heat dissipation efficiency. The heat sink 201 may be made of materials such as graphite and metal. In the case where the second body 200 has a metal shell, the second heat conductor 420 may be directly connected to the metal shell of the second body 200, so that the heat can be transferred to the metal shell and then dissipated into the surrounding air.

[0057] In some embodiments, the target component 330 may include a first target component 331 and a second target component 332, and an annular body 800 is provided on at least one of the first heat conductor 410 and the second heat conductor 420, and the annular body 800 is located between the first target component 331 and the second target component 332, and is fixedly connected or rotatably connected to the heat conductive component 400, and the target surface of the annular body 800 is in contact with at least one of the first target component 331 and the second target component 332.

[0058] like Figure 6~Figure 9 As shown, the target component 330 can be set to two, namely the first target component 331 and the second target component 332. The two target components 330 can be configured so that one of them mainly plays a heat conduction role, while the other, although it also plays a heat conduction role, mainly plays a supporting role for the first heat conductor 410 and the second heat conductor 420. In other words, the target component 330 that mainly plays a heat conduction role has a higher thermal conductivity than the target component 330 that mainly plays a supporting role. In the first target component 331 and the second target component 332, the target component 330 that mainly plays a heat conduction role takes thermal conductivity as a priority consideration when selecting materials, and the requirements for material strength can be relaxed, while the target component 330 that mainly plays a supporting role takes strength as a priority consideration when selecting materials, and the requirements for material thermal conductivity can be relaxed. Therefore, by setting two target components 330 that mainly play a heat conduction role and mainly play a supporting role, it is easier and more flexible to select materials when making the target component 330.

[0059] exist Figure 7 In the exemplary embodiment, the first target component 331 may mainly play a heat conduction role, and the second target component 332 may mainly play a supporting role, that is, the first heat conductor 410 and the second heat conductor 420 transfer more heat through the first target component 331. Fig. 9 , each target component 330 may have two hinge holes as connecting parts, which are respectively used to connect the first heat conductor 410 and the second heat conductor 420, and the heat is transferred through the parts of the first heat conductor 410 and the second heat conductor 420 corresponding to the hinge holes, that is, the heat is transferred through the annular surface. In order to minimize the space occupied by the target component 330, the axial size and radial size of the hinge hole can be made as small as possible, which will affect the area of ​​the annular surface for transferring heat, and then affect the heat dissipation efficiency. In order to better solve this problem, an annular body 800 can be provided on the heat conductor, and the annular body 800 is sleeved on the outer surface of the heat conductor, and can be fixedly connected or rotatably connected to the heat conductor. By providing the annular body 800, the area for transferring heat is increased, which is conducive to improving the heat dissipation efficiency.

[0060] The annular body 800 can be a part sleeved on the heat-conducting member, that is, the annular body 800 and the heat-conducting member are made separately and then assembled together. The annular body 800 can also be integrally formed with the heat-conducting member, that is, the annular body 800 and the heat-conducting member are an integrated structure. The annular body 800 can be made of a material with a higher thermal conductivity so that the annular body 800 provides a better heat-conducting function. For example, the material of the annular body 800 can be set to copper, aluminum, silver, graphene, carbon nanotubes, ceramic materials, etc. The target surface of the annular body 800 is the surface of the annular body 800 exposed to the outside relative to the first heat-conducting member 410 and / or the second heat-conducting member 420, such as the side of the annular member, the outer surface of the annular member, etc. The contact between the target surface of the annular body 800 and the target component 330 can be different situations such as rotating contact and static contact. An annular body 800 is provided on at least one of the first heat conductor 410 and the second heat conductor 420, which includes three situations: in the first situation, the annular body 800 is provided only on the first heat conductor 410; in the second situation, the annular body 800 is provided only on the second heat conductor 420; in the third situation, the annular body 800 is provided on both the first heat conductor 410 and the second heat conductor 420.

[0061] The target surface of the annular body 800 contacts at least one of the first target component 331 and the second target component 332, so that heat can be transferred between the annular body 800 and the target component 330. In some embodiments, the target surface of the annular body 800 can be arranged to extend along the radial direction of the shaft assembly 600, that is, the target surface extends in a direction that satisfies the vertical condition with the first axis Z1 and / or the second axis Z2 of the shaft assembly 600, and the contact surface of the heat conductive component 400 and the target component 330 can be arranged to extend along the axial direction of the shaft assembly 600, that is, the surface of the portion of the heat conductive component in contact with the target component 330 extends in a direction that satisfies the parallel condition with the first axis Z1 and / or the second axis Z2 of the shaft assembly 600, and the area of ​​the target surface is larger than the area of ​​the contact surface. That is to say, the target surface of the annular body 800 for contacting the target component 330 is set as a plane that satisfies the vertical condition with the rotation axis of the shaft assembly 600, and the surface of the heat conductive component 400 that is used to contact the target component 330 is set as an annular surface that satisfies the parallel condition with the rotation axis of the shaft assembly 600, and the area of ​​the annular surface is smaller than the area of ​​the above-mentioned plane. In this way, when the portion of the heat conductive component connected to the target component 330 is made thinner, although the area of ​​the portion where the heat conductive component contacts the target component 330 becomes smaller, since the annular body 800 is provided on the heat conductive component, heat is transferred through the contact between the target surface of the annular body 800 and the target component 330, thereby ensuring that the heat transfer efficiency is not affected. Therefore, under the requirement of the same heat transfer efficiency, the portion of the heat conductive component connected to the target component 330 can be made thinner, thereby reducing the space occupied by this part of the heat conductive component.

[0062] In some embodiments, at least one of the first target component 331 and the second target component 332 can be set as a movable component that can move relative to the heat-conducting component 400 along the axial direction of the rotating shaft component 600, that is, the movable component can move relative to the heat-conducting component along the direction that satisfies the parallel condition with the first axis Z1 and / or the second axis Z2 of the rotating shaft component 600, and the target surface of the annular body 800 contacts the movable component; the electronic device includes an elastic member 700 that provides a target force to the movable component, and the direction of the target force is the direction from the movable component to the annular body 800. At least one of the first target component 331 and the second target component 332 can be set as a movable component, including three situations: in the first situation, only the first target component 331 is set as a movable component; in the second situation, only the second target component 332 is set as a movable component; in the third situation, both the first target component 331 and the second target component 332 are set as movable components.

[0063] exist Figure 7In the exemplary embodiment, the first target component 331 can be set as a movable component, which can move relative to the heat conductive component along the axial direction of the hinge hole connected to the heat conductive component, and the direction of the elastic restoring force of the elastic component 700 is from the first target component 331 to the direction close to the annular body 800 (i.e. Figure 7 In the direction indicated by the solid arrow in the figure), the first target component 331 can be in closer contact with the annular body 800 under the action of the elastic restoring force of the elastic member 700, so that the heat can be transferred between the first target component 331 and the annular body 800 more quickly. Moreover, when the first target component 331 and the annular body 800 rotate relative to each other, the first target component 331 and the annular body 800 may lose material due to mutual friction, resulting in a reduction in the axial size of the hinge hole. The elastic restoring force of the elastic member 700 can be used to move the first target component 331 toward the annular body 800, so that the two always maintain close contact.

[0064] There are many options for the structure and arrangement of the elastic member 700. Figure 7 In the exemplary embodiment, the elastic member 700 can be configured as a coil spring and arranged between the first target component 331 and the partition 320. In other embodiments, the elastic member 700 can also be configured as a spring structure and can be composed of Figure 7 The compression spring shown is changed into a tension spring and arranged between the first target component 331 and the second target component 332. However, the present application is not limited thereto, that is, those skilled in the art can adjust or set the type of the elastic member 700 according to specific needs.

[0065] like Figure 7 As shown, in order to facilitate the installation of the elastic member 700, the first target component 331 can be provided with a guide column 3311, and the elastic member 700 is sleeved on the guide column 3311. In other embodiments, the elastic member 700 can also be sleeved on the portion of the heat-conducting member located between the partition 320 and the first target component 331. For example, the first heat-conducting member 410 and the second heat-conducting member 420 are each sleeved with a coil spring to provide a more balanced force for the first target component 331, so as to better avoid the first target component 331 from being stuck due to uneven force when moving along the heat-conducting member. On this basis, an annular body 800 rotatably connected to the heat-conducting member can be added on the side of the first target component 331 away from the second target component 332, so that the annular body 800 is provided on both sides of the first target component 331 to further improve the heat dissipation efficiency. It should be understood that, under the action of the elastic member 700 sleeved on the heat conductive member, the annular body 800 located on the side of the first target component 331 away from the second target component 332 is always in close contact with the first target component 331 .

[0066] exist Figure 7 and Figure 8In the exemplary embodiment, the portion of the heat conductor 300 that is rotatably connected to the target component 330 can be set to a cylindrical shape, that is, the cross-section of the heat conductor 300 at each rotational contact portion is equal. In this structure, the heat conductor 300 is in rotational contact with the target component 330 only in radial direction, that is, in radial direction of the hinge hole. In other embodiments, such as Fig.15 As shown, the portion of the first heat-conducting member 410 that is rotatably connected to the first connecting portion may include a first portion 4111 and a second portion 4112 with different cross-sectional sizes, so that the first heat-conducting member 410 and the first connecting portion meet axial contact and radial contact conditions, that is, both axial contact conditions and radial contact conditions are met. Axial contact refers to contact along a direction that meets the parallel condition with the first axis Z1 and / or the second axis Z2 of the rotating shaft assembly 600, and radial contact refers to contact along a direction that meets the perpendicular condition with the first axis Z1 and / or the second axis Z2 of the rotating shaft assembly 600. That is to say, the diameters of the first part 4111 and the second part 4112 are not equal, so the first part 4111 and the second part 4112 have a height difference in the radial direction, and the transition connection surface formed by the height difference provides the first heat conductor 410 with the axial contact of the first connection part, that is, the axial contact of the hinge hole, and at the same time, the cylindrical outer peripheral surface of the first part 4111 and the second part 4112 also provides the first heat conductor 410 with the first connection part. The contact of the rotation of the first heat conductor 410 and the first connection part includes radial contact and axial contact at the same time, that is, the axial contact and radial contact conditions are met. Through such a structural design, the contact area of ​​the first heat conductor 410 and the first connection part is increased, which is conducive to improving the heat transfer efficiency between the two. Similarly, the part of the second heat conductor 420 that is rotatably connected to the second connection part can include a third part and a fourth part with different cross-sectional dimensions, so that the second heat conductor 420 and the second connection part meet the axial contact and radial contact conditions, so that it is conducive to improving the heat transfer efficiency between the second heat conductor 420 and the second connection part.

[0067] In some embodiments, the electronic device may include a connection component 300 connecting the shaft component 600 and the heat-conducting component 400, the connection component 300 includes a shell 310 and a target component 330, the shell 310 has a first accommodating space K1 and a second accommodating space K2 distributed along the axial direction of the shaft component 600, that is, the first accommodating space K1 and the second accommodating space K2 are sequentially arranged along a direction that satisfies the parallel condition with the first axis Z1 and / or the second axis Z2 of the shaft component 600. The first accommodating space K1 accommodates a part of the shaft component 600, that is, a part of the shaft component 600 is arranged in the first accommodating space K1, the second accommodating space K2 accommodates a part of the heat-conducting component 400, that is, a part of the heat-conducting component 400 is arranged in the second accommodating space K2, and the target component 330 is arranged in the second accommodating space K2. See. Figure 5, Figure 6 and Fig.10 , one end of the first heat conducting member 410 close to the target component 330 and one end of the second heat conducting member 420 close to the target component 330 extend into the second accommodation space K2 of the shell 310, and the end of the shell 310 away from the target component 330 is provided with an entrance and exit of the first accommodation space K1. After the connection component 300 and the heat conducting component 400 are assembled, they can be Fig.10 As shown by the middle arrow C, the shell 310 is put onto a part of the shaft assembly 600, so that the shaft assembly 600 and the heat-conducting assembly 400 are assembled together to form a heat-conducting shaft module. In this way, when producing electronic equipment, the shaft assembly 600 and the heat-conducting assembly 400 can be first assembled into the heat-conducting shaft module, and then the heat-conducting shaft module can be assembled as a whole to the first body 100 and the second body 200. Compared with the method of assembling the shaft assembly 600 and the heat-conducting assembly 400 to the first body 100 and the second body 200 respectively, it is easier to ensure that the rotation center line of the heat conductor and the rotation center line of the corresponding shaft meet the colinear condition.

[0068] See also Figure 1~Figure 3 and Fig.10 , part of the hinge assembly 600 and part of the heat-conducting assembly 400 are accommodated in the shell 310, and only the shell 310 is exposed at the rotation connection between the first body 100 and the second body 200, and the other parts of the heat-conducting hinge module are arranged inside the first body 100 and the second body 200, that is, the first hinge 610 and the part of the first heat-conducting member 410 located outside the shell 310 are hidden inside the first body 100, and the second hinge 620 and the part of the second heat-conducting member 420 located outside the shell 310 are hidden inside the second body 200. In this way, the structure seen by the user after rotating and opening the first body 100 and the second body 200 is relatively simple.

[0069] In some embodiments, a partition 320 may be disposed inside the housing 310, and the partition 320 separates the first accommodation space K1 from the second accommodation space K2. The second accommodation space K2 has a closed cavity defined by the partition 320, the housing 310, and the target component 330, and the closed cavity is filled with a heat-conducting medium. Figure 5~Figure 7The partition 320 blocks the first storage space K1 and the second storage space K2, which can reduce the influence of the heat of the second storage space K2 on the shaft assembly 600. For example, when some parts of the shaft assembly 600 are easily affected by high temperature and age, the transfer of heat to the first storage space K1 is not expected. By setting the partition 320 to make the first storage space K1 and the second storage space K2 independent of each other, the transfer of heat to the first storage space K1 can be reduced to a certain extent. On the basis of the partition 320, a heat-conducting medium can be filled in the closed cavity between the partition 320 and the target component 330. The heat-conducting medium can conduct heat faster than air, so it is helpful to improve the heat transfer efficiency between the first heat-conducting member 410 and the second heat-conducting member 420. The heat-conducting medium can be a fluid, or it can be a thermal grease, etc., which is not limited in this application.

[0070] exist Figure 7 and Figure 8 In the exemplary embodiment, the sealed cavity can be defined by the partition 320, the shell 310 and the second target component 332, and the first target component 331 is located in the sealed cavity. In order to improve the airtightness of the sealed cavity and prevent the heat-conducting medium from flowing out from the hinged position between the second target component 332 and the heat-conducting member, a sealing ring 900 can be provided at the hinged position between the second target component 332 and the heat-conducting member. The second target component 332 can be provided with a positioning portion 3321 for cooperating with the sealing ring 900, so that the sealing ring 900 can be more stably maintained in the installed position. Figure 7 As shown, the sealing ring 900 is located between the annular body 800 and the second target component 332 and contacts the annular body 800. When the annular body 800 is fixedly connected to the heat conductor, the annular body 800 will rotate relative to the sealing ring 900 during the rotation of the heat conductor relative to the second target component 332. In this case, the sealing ring 900 can be made of wear-resistant material, thereby reducing the wear of the annular body 800 on the sealing ring 900 and effectively preventing leakage of the heat-conducting medium at the sealing ring 900.

[0071] In some embodiments, the electronic device may include a threading tube 500 for laying cables, that is, the threading tube 500 provides a channel for passing cables, and the cables connect the first body 100 and the second body 200. The threading tube 500 may include a bending portion 510 arranged in the first accommodating space K1, and the first tube segment of the bending portion 510 is arranged along the first axis Z1 to pass through the first rotating shaft 610, and the second tube segment of the bending portion 510 is arranged along the second axis Z2 to pass through the second rotating shaft 620, that is, the first tube segment and the second tube segment are the parts of the bending portion 510 located inside the first rotating shaft 610 and the second rotating shaft 620, respectively. Figure 4 , Figure 5 and Fig.10There may be a need for electrical connection between the first body 100 and the second body 200. For example, when the electronic device is a laptop computer, the screen end and the system end need to be electrically connected through a cable. The bending portion 510 of the threading tube 500 arranged in the first accommodation space K1 can be set to a U shape, and the threading tube 500 is in a shape of a "J". The threading tube 500 passes through the first rotating shaft 610 along the first axis Z1, then bends in the first accommodation space K1 of the shell 310, and then passes through the second rotating shaft 620 along the second axis Z2. The threading tube 500 is combined with the hollow structure of the rotating shaft assembly 600, which can improve the utilization of space and make the components of the electronic device more compact.

[0072] After the first body 100 and the second body 200 of the electronic device are rotated and opened, they can rely on the torque provided by the shaft assembly 600 and the torque provided by the heat-conducting assembly 400 to maintain the open state for the user to use the electronic device. In some embodiments, during the relative rotation of the first body 100 and the second body 200, the shaft assembly 600 provides a first friction force, that is, the torque formed at the shaft assembly 600, and the relative rotation of the heat-conducting assembly 400 and the target component 330 provides a second friction force, that is, the torque formed at the connection between the heat-conducting assembly 400 and the target component 330, and the second friction force is less than the first friction force. In other words, after the first body 100 and the second body 200 are rotated and opened, they mainly rely on the torque provided by the shaft assembly 600 to maintain the open state, which can reduce the requirements for the heat-conducting assembly 400 and the target component 330 in terms of torque provision, making the selection of materials for the heat-conducting assembly 400 and the target component 330 more flexible and diverse. In some embodiments, the first heat conductive member 410 and / or the second heat conductive member 420 may be configured as a heat pipe, which utilizes the phase-changeable working fluid flowing inside the heat pipe to quickly transfer heat, thereby enabling the heat conductive component 400 to have a higher heat dissipation efficiency.

[0073] In some embodiments, the rotation stroke of one of the first rotating shaft 610 and the second rotating shaft 620 is a first angle, and the rotation stroke of the other is a second angle, and the sum of the first angle and the second angle can be 180° or 360°. The rotation stroke refers to the maximum angle that can be rotated within the rotatable range. The rotation range provided by the rotating shaft assembly 600 is the sum of the rotation ranges provided by the first rotating shaft 610 and the second rotating shaft 620. The rotation range provided by the rotating shaft assembly 600 limits the maximum angle that the first body 100 and the second body 200 can be opened. This maximum angle can be set as needed, for example, to 160°, 180°, 270° or 360°, and of course, it can also be set to other angle values. Taking the maximum angle of 360° that the first body 100 and the second body 200 can be opened as an example, the first body 100 and the second body 200 can be rotated 360° relative to the first stacking state of 0° to switch to the second stacking state, so that the two surfaces of the first body 100 and the second body 200 that face each other in the first stacking state of 0° (such as the input surface of the system end and the display surface of the screen end) become two surfaces facing each other in the second stacking state of 360°. With this arrangement, the electronic device can be opened not only to the form of an ordinary laptop computer, but also to the form of a tablet computer, meeting the various needs of users. It should be noted that the maximum angle that the first body 100 and the second body 200 can be opened is relative to the 0° of the stacking state of the two, that is, the maximum angle refers to the angle range of the first body 100 and the second body 200 relative to 0°.

[0074] In addition, the ratio between the first angle provided by the first rotating shaft 610 and the second angle provided by the second rotating shaft 620 can be flexibly set as needed. Taking the sum of the first angle and the second angle as 180° as an example, the first angle and the second angle can be both set to 90°, or the first angle can be set to 60° and the second angle can be set to 120°, or the first angle can be set to 100° and the second angle can be set to 80°.

The cross-sections of the first cylinder 411 are circular at various locations, the cross-sections of the first flat body 413 are rectangular or approximately rectangular at various locations, the cross-section of one end of the first transition body 412 connected to the first cylinder 411 is circular, the cross-section of one end of the first transition body 412 connected to the first flat body 413 is rectangular or approximately rectangular, and the cross-section shapes of the first transition body 412 along the direction from the first cylinder 411 to the first flat body 413 are different depending on the position. The end of the first heat conducting member 410 close to the target component 330 needs to be rotatably connected to the first connecting portion of the target component 330, and this end of the first heat conducting member 410 is set as the first cylinder 411, so as to facilitate the rotatable connection with the target component 330. The first flat body 413 is configured as one end of the first heat conducting member 410 away from the target component 330, so that it can be better arranged in the first body 100 and connected to the target heat generating component 101. The cross-section of each part of the first transition body 412 changes gradually, achieving a smooth transition connection from round to flat. Fig.12 As shown, the second heat conductor 420 may include a second cylinder 421 , a second flat body 423 , and a second transition body 422 of variable cross-section connecting the second cylinder 421 and the second flat body 423 , wherein the second cylinder 421 is rotatably connected to the second connection portion of the target component 330 .

[0076] In other embodiments, the heat conducting member may be configured in other structural forms, for example, all parts of the heat conducting member are configured in a cylindrical shape. In addition, the structural forms of the first heat conducting member 410 and the second heat conducting member 420 may be the same or different, and this application does not limit this. Fig.10 In the exemplary embodiment, the first heat conducting member 410 and the second heat conducting member 420 can both be configured to have a cylindrical body, a flat body, and a transitional body from a round body to a flat body. In other embodiments, one of the first heat conducting member 410 and the second heat conducting member 420 can be changed to a cylindrical structure in which all parts are cylindrical, while the other can be kept as a cylindrical structure. Fig.10 The structural form shown remains unchanged.

Similarly, the second heat-conducting member 420 may be configured to be in a Z-shaped or S-shaped shape with a bend from the perspective of the rotation center line of the second rotating shaft 620, so as to facilitate the arrangement of the second heat-conducting member 420 in the second body 200.

[0078] In some embodiments, a heat conducting sheet 103 may be disposed between the first heat conducting member 410 and the target heat generating component 101, and the heat conducting sheet 103 provides a larger support area for the first heat conducting member 410, so that the first heat conducting member 410 is more firmly connected to the target heat generating component. The heat conducting sheet 103 may be configured as a metal sheet, such as a copper sheet, an aluminum sheet, etc., which can effectively improve the heat dissipation effect on the target heat generating component 101 while providing support for the first heat conducting member 410. A heat conducting paste 102 may be disposed between the heat conducting sheet 103 and the target heat generating component 101, and the heat conducting paste 102 can fill the small gap that may exist between the heat conducting sheet 103 and the target heat generating component 101, so that heat can be better transferred between the heat conducting sheet 103 and the target heat generating component 101.

[0079] In some embodiments, in order to make the first body 100 thinner, the Fig.13 The heat conducting sheet 103 is arranged such that, for example, the first heat conducting member 410 is in direct contact with the surface of the heat generating component. Fig.14 In the absence of the heat conductive sheet 103, the first heat conductive member 410 may include an overlapping portion bent and arranged on the surface of the target heat generating component 101, and the overlapping portion is bent and extended, thereby increasing the contact area between the first heat conductive member 410 and the target heat generating component 101, and can improve the stability of the connection between the first heat conductive member 410 and the target heat generating component 101 and the efficiency of heat transfer.
