Background

For terminal devices such as mobile phones, many folding machines have appeared in the market at present, and the folding forms include an inner folding type and an outer folding type, that is, the display screen is respectively located at the inner side and the outer side after folding.

Referring to fig. 5 and 6, the rotation mechanism 10 has a rotation axis (the rotation axis refers to the Z-axis in fig. 6, and the rotation axis may be disposed perpendicular to the plane of the drawing in fig. 5) to rotate the door panel assembly 100 to an unfolded configuration (as shown in fig. 5) or a folded configuration, thereby rotating in synchronization with the first and second housings 410 and 420 of the terminal device. Referring to fig. 5, when the door panel assembly 100 is in the unfolded configuration, the first connection side 101 is configured to rotate about the rotation axis toward the second connection side 102, such as the first connection side 101 rotates in the direction W1 in fig. 5 and rotates toward the second connection side 102; when the rotation mechanism 10 is provided with a synchronization mechanism that rotates the first housing 410 and the second housing 420 in synchronization, since the first connection side portion 101 is connected to the first housing 410 and the second connection side portion 102 is connected to the second housing 420, the second connection side portion 102 will also rotate in synchronization about the rotation axis toward the first connection side portion 101, such as the second connection side portion rotating in the W2 direction in fig. 5 toward the first connection side portion 101. When the door panel assembly 100 is in the folded configuration, the first connecting side 101 is configured to rotate about the axis of rotation away from the second connecting side 102, as shown in the unfolded configuration of fig. 5.

In this embodiment, by providing the rotation mechanism 10 to include the door panel assembly 100 and the door panel assembly 100 includes the heat dissipation structure 200, the heat dissipation structure 200 can be used to connect the heat generating device 540 on the terminal device, such as the heat generating device 540 is connected to the heat dissipation structure 200 through the first heat conduction connection member 320, so that the rotation mechanism 10 can dissipate heat of the terminal device, which is beneficial to improving heat dissipation efficiency.

In particular, referring to fig. 5 and 6, in an alternative embodiment, the door panel assembly 100 further includes a first door panel 110 and a second door panel 120, the first door panel 110 and the second door panel 120 being arranged in a direction perpendicular to the axis of rotation (the arrangement refers to an arrangement between a single first door panel 110 and a single second door panel 120), such as being arranged in a left-right direction in fig. 5. The second door panel 120 may be disposed on both sides of the first door panel 110, or the second door panel 120 may be disposed on only one side of the first door panel 110, which is not limited in this embodiment.

The heat radiation structure 200 includes a first heat radiation body 210 and a second heat radiation body 220, and the first heat radiation body 210 and the second heat radiation body 220 are arranged in a direction perpendicular to the rotation axis (the arrangement refers to an arrangement between the single first heat radiation body 210 and the second heat radiation body 220), such as being arranged in a left-right direction in fig. 6. The first radiator 210 is disposed on the first door panel 110, and the second radiator 220 is disposed on the second door panel 120, specifically, may be in the form of electroplating or snap connection.

The heat conductivity of the first heat sink 210 may be set to be greater than that of the first door panel 110. Illustratively, the first door panel 110 may include a metal layer, such as a relatively ductile metal, such as stainless steel. The first heat sink 210 may be provided to include a first heat sink layer laminated on the metal layer, for example, by electroplating or snap-in connection. The first heat dissipation layer is for facing the display screen, and the heat dissipation layer may be provided to include at least one of a copper layer, a tin layer, a graphene layer, and a graphite sheet. Wherein, the copper layer and the tin layer can be arranged on the metal layer in an electroplating way. The heat conductivity of the second heat sink 220 is greater than that of the second door panel 120. Illustratively, the second heat sink 220 may be provided to include at least one of a copper layer, a tin layer, a graphene layer, and a graphite sheet, the second door 120 may be provided as a steel plate, etc., to which the present embodiment is not limited. In a folded state of the terminal device, the display screen is at a certain distance from the rotating mechanism 10, i.e. the display screen is not supported by the rotating mechanism 10, so as to avoid the display screen from being squeezed by the rotating mechanism 10; there is still a possibility that the folded state of the display screen is abnormal, a part of the members of the rotating mechanism 10 is abnormally protruded, or the like. In this embodiment, the flexibility of the copper layer, the tin layer, the graphene layer and the graphite sheet is relatively good (compared with stainless steel and the like), so that in the folded state, even if the display screen is forcibly dragged by the first radiator 210, that is, the display screen touches the first radiator 210, the display screen still can utilize the better flexibility of the first radiator 210, and the extrusion stress of the touch position of the display screen and the door panel is reduced through the deformation of the first radiator 210, so that the risk of the display screen being extruded is reduced, and therefore, the display screen and the terminal equipment have better reliability.

Of course, the door panel assembly 100 may also be configured to include only the first door panel 110 and the first heat sink 210, that is, the door panel assembly 100 is a monolithic plate structure; the first radiator 210 is disposed on the first door panel 110, and a thermal conductivity of the first radiator 210 is greater than that of the first door panel 110. In this embodiment, the first door panel 110 can be made of a material with better ductility to facilitate the rotation of the rotation mechanism 10, and then radiate heat through the first radiator 210, so that the rotation mechanism 10 has better rotation performance and higher heat radiation capability.

In the turning mechanism 10 illustrated in fig. 5 and 6, the first door panel 110 of the door panel assembly 100 may be configured to be fixedly coupled to the second door panel 120, and the first door panel 110 and the second door panel 120 remain in contact in the folded configuration, where the door panel assembly 100 may be referred to as a unitary door panel. Of course, referring to fig. 10, the door panel assembly 100 may be configured as a floating door panel, that is, the first door panel 110 and the second door panel 120 in the door panel assembly 100 are separated to form a separation gap in a folded configuration, and the first door panel 110 and the second door panel 120 may be connected by a transmission mechanism in a transmission manner to realize the conversion between the unfolded configuration and the folded configuration. In the case where the door panel assembly 100 is configured as a floating door panel, the door panel assembly 100 may be configured with only the heat dissipation structure 200, that is, without the first door panel 110 and the second door panel 120. In the case that the door panel assembly 100 is configured as a floating door panel or the like, when the door panel assembly 100 is in the unfolded state, the first heat radiator 210 and the second heat radiator 220 are connected to conduct heat, and the door panels (i.e., the door panels composed of the heat dissipation structure 200) that the rotation mechanism 10 can conduct heat are connected in series, so that the heat conduction efficiency between the door panels is improved, and the heat dissipation capability of the door panel assembly 100 is improved.

In another alternative embodiment, the heat dissipation structure 200 includes the first heat dissipation layer and the first door panel 110, where the first heat dissipation layer is stacked on the first door panel 110; the first heat dissipation layer is used for towards the display screen, the elastic modulus of first heat dissipation layer is less than the elastic modulus of first door plant 110, namely, the first heat dissipation layer is better for first door plant 110 flexibility, help under folding form, even the display screen is pulled by first heat dissipation layer by force, the display screen is touched by first heat dissipation layer promptly, the display screen still can utilize the better flexibility of first heat dissipation layer, deformation through first heat dissipation layer reduces the extrusion stress of the touch position of display screen and door plant, reduce the risk that the display screen was crowded to be injured, thereby make display screen and terminal equipment possess better reliability.

Further alternatively, referring to fig. 5, the first door panel 110 may be configured to be fixedly coupled to the second door panel 120. For example, referring to fig. 5 and 9, a side of the second door panel 120 facing the first door panel 110 (e.g., a right side of the second door panel 120 in fig. 9) is provided with a support boss 130, and a side of the support boss 130 along a thickness direction of the second door panel 120 (e.g., an upper side in the figures) is provided with a support surface 131, and the support surface 131 is disposed facing a panel surface of the first door panel 110. The second heat sink 220 may extend to the supporting surface 131, and two sides of the second heat sink 220 are respectively abutted to the plate surface of the first door panel 110 and the supporting surface 131. Referring to fig. 6, the first door panel 110 is provided with a first through structure 111 (such as a through hole, a notch, etc.) and a metal fixing member 113 (such as a screw, a bolt, a rivet, etc. fastening member, a weld, etc.), the first through structure 111 extends into the supporting boss 130, and the metal fixing member 113 extends into the first through structure 111 to fix the first door panel 110 and the second door panel 120; as shown in fig. 5 and 6, the metal fixing member 113 may be provided as a screw, and the first door panel 110 and the first heat sink 210 may be fixed by a screw thread at an upper end of the screw by abutting the nut 113a of the screw against the lower side of the support boss 130 of the second door panel 120. Of course, the metal fixing member 113 may also be used to fix the first door panel 110 and the second door panel 120 by riveting, welding, or the like, that is, it is only required to realize that one end of the metal fixing member 113 is abutted against the first heat sink 210 and the other end of the metal fixing member 113 is abutted against the second heat sink 220, which is not limited in this embodiment.

In this embodiment, the support boss 130 can support the first door panel 110 and the first radiator 210, so as to reduce the risk of failure (detachment, disconnection, etc.) of the fixed connection between the first door panel 110 and the second door panel 120, and the fixed connection between the first radiator 210 and the second radiator 220. By making one end of the metal fixture 113 abut against the first radiator 210 and the other end of the metal fixture 113 abut against the second radiator 220, the metal fastener 113 can perform heat conduction between the first radiator 210 and the second radiator 220 while achieving the fixed connection between the first door panel 110 and the second door panel 120, thereby simultaneously improving the heat transfer efficiency and the connection stability between the first radiator 210 and the second radiator 220.

Further alternatively, referring to fig. 5, the supporting surface 131 and the second door 120 have a height difference along the thickness direction of the second door 120 (shown by a dimension H in the drawing), so that the thickness of the first door 110 and the first radiator 210 is accommodated by the height difference, which is beneficial to reducing the protrusion amount (such as reducing the protrusion amount facing upwards in fig. 5) at the position of the first door 110 and the first radiator 210 in the door assembly 100, and reducing the risk that the corresponding display screen is knocked in the flattened state.

Further as an alternative embodiment, the door panel assembly 100 further comprises a second thermally conductive connector 310, such as a thermally conductive adhesive or the like. The second heat conductive connection 310 is at least partially disposed between the first heat sink 210 and the second heat sink 220; when the door panel assembly 100 is in the unfolded configuration, the two sides of the second heat conductive connecting piece 310 are respectively abutted against the first heat sink 210 and the second heat sink 220, so as to further improve the heat transfer efficiency between the first heat sink 210 and the second heat sink 220. Illustratively, both sides of the second heat conductive connector 310 are fixedly connected to the first heat sink 210 and the second heat sink 220, respectively, such as in the form of bonding.

Further alternatively, a predetermined gap may be provided between the side edge of the first door panel 110 and the second door panel 120, and at least a portion of the second thermally conductive connector 310 is disposed within the predetermined gap. The preset gap can reduce the risk of assembly interference between the first door panel 110 and the second door panel 120, is beneficial to improving the assembly efficiency of the rotating mechanism 10 and the terminal equipment, and can reduce the internal stress between the first door panel 110 and the second door panel 120, thereby improving the durability of the rotating mechanism 10 and the terminal equipment.

In this embodiment, when the door panel assembly 100 is in the folded configuration, the first door panel 110 is in a folded state to effectively accommodate the folded portion of the display screen.

At this time, the second penetrating structure 112 is beneficial to improving the smoothness of bending the first door panel 110 and ventilation, so as to further improve the heat dissipation capability of the first door panel 110 or the first heat dissipation body 210.

In another alternative embodiment, referring to fig. 5, a second filler structure 121 is disposed within the second door panel 120, the second filler structure 121 having a strength greater than that of the second door panel 120, the second filler structure 121 extending in a direction parallel to the axis of rotation, such as extending in a direction facing inward in the view of fig. 5. Illustratively, the second door skin 120 may be made of a plastic material, and the second filler structure 121 may be provided as a reinforced steel sheet; that is, the second filling structure 121 may be filled into the second door panel 120 by encapsulation or the like to enhance the structural strength of the second door panel 120.

Of course, referring to fig. 5, the second filling structure 121 may be configured to include a second heat dissipating tube, which may be configured as a flat tube as shown in fig. 5, a circular tube, an elliptical tube, etc., which is not limited in this embodiment. The second radiating pipe may be provided as a radiating copper pipe, for example. The second radiating pipe is abutted with the second radiator 220, so that the structural strength of the second door 120 is improved, and meanwhile, the radiating capacity of the second door 120 is further improved. Of course, the second radiator 220 may be directly configured as a radiating pipe (such as a radiating copper pipe, etc.), where the second radiator 220 may be filled in the second door 120 in an encapsulated manner, and the side wall surface of the second radiator 200 extends out of the second door 120 to radiate heat.

Part of the first heat conductive connecting piece 320 is abutted with the first heat radiation body 210, and the other part of the first heat conductive connecting piece 320 is abutted with the second heat radiation body 220, so that heat conduction between the first heat radiation body 210 and the second heat radiation body 220 is realized through the first heat conductive connecting piece 320, and the heat radiation efficiency is improved.

Of course, in another alternative embodiment, when the door panel assembly 100 is in the unfolded configuration, the side edge of the first heat sink 210 abuts against the side edge of the second heat sink 220, that is, the first heat sink 210 and the second heat sink 220 conduct heat through direct contact, so as to improve heat dissipation efficiency. In addition, the rotating mechanism 10 may further be provided with the second heat conductive connection member 310, and one of the first heat radiator 210 and the second heat radiator 220 is fixedly connected to the second heat conductive connection member 310; when the door panel assembly 100 is in the folded configuration, the other of the first heat sink 210 and the second heat sink 220 is spaced apart from the second heat conductive connector 310.

In this embodiment, the door panel assembly 100 may further include a transmission structure through which the first door panel 110 and the second door panel 120 are connected. The transmission structure may be provided as a crank-like slider mechanism or a link mechanism formed of a slide groove, a connecting arm, or the like, for example, which is not limited in this embodiment. Further, the second door panel 120 may also include at least two sub-door panels, which are connected to the second door panel 120 through the above-mentioned transmission structure, so as to enable the door panel assembly 100 to be unfolded and folded.

Further, referring to fig. 11 to 13, since the first door panel 110 itself does not need to be bent, the first heat radiator 210 may be configured to include at least one of the first heat radiating layer and the first heat radiating pipe 211, and the first heat radiating layer may be configured to be stacked on the first door panel 110; the first radiating pipe 211 may be disposed to be at least partially disposed within the first door panel 110, such as by an encapsulation process. As described with reference to the drawings, the first heat sink 210 is provided as a first heat dissipating tube 211 (the shape includes square tube, flat tube, circular tube, etc., and the present embodiment is not limited thereto), for example, the first heat dissipating tube 211 may be provided as a heat dissipating copper tube. Referring to fig. 13 (the first door panel 110 in fig. 12 is hidden), the lumen of the first radiating pipe 211 is in a closed state, and heat can be radiated by the phase change of the internal heat radiating medium. When the first heat sink 210 includes the first heat dissipating tube 211, the heat dissipating capability of the rotating mechanism 10 and the corresponding terminal device is further improved.

The foregoing is merely exemplary embodiments of the present application, and any person skilled in the art may easily conceive of changes or substitutions within the technical scope of the present application, which should be covered by the present application. The protection scope of the present application shall be subject to the protection scope of the claims.
