[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0056] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0057] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0058] This utility model provides an electronic device. (See reference...) Figures 1 to 23 The electronic device 1 provided in this embodiment of the present invention includes: a hinge mechanism 100, a first frame 210, a second frame 220, a heat sink 300, a reinforcing sheet 400, and a display module 500.

[0059] The first frame 210 and the second frame 220 are respectively connected to opposite sides of the hinge mechanism 100 so as to move with the hinge mechanism 100 during folding or unfolding. For example, when the hinge mechanism 100 is in the folded state, the first frame 210 and the second frame 220 are opposite each other. When the hinge mechanism 100 is in the unfolded state, the top surfaces of the first frame 210 and the second frame 220 are flush.

[0060] The heat sink 300 extends from a position opposite to the first frame 210 to a position opposite to the second frame 220. For example, if the area of ​​the electronic device 1 located in the first frame 210 has high heat, the heat sink 300 can transfer the heat from that area to the area of ​​the electronic device 1 located in the second frame 220. Similarly, if the area of ​​the electronic device 1 located in the second frame 220 has high heat, the heat sink 300 can transfer the heat from that area to the area of ​​the electronic device 1 located in the first frame 210. In this way, by utilizing the heat sink 300 for heat transfer, excessively high local temperatures in the electronic device 1 can be avoided.

[0061] The portion of the heat sink 300 opposite to the hinge mechanism 100 and the reinforcing plate 400 are fixedly connected. The display module 500 is located on the side of the heat sink 300 away from the hinge mechanism 100.

[0062] In this way, in the embodiment of the present invention, since the part of the heat sink 300 opposite to the hinge mechanism 100 is fixedly connected to the reinforcing plate 400, the reinforcing plate 400 can be used to prevent the part of the heat sink 300 opposite to the hinge mechanism 100 from local arching, thereby avoiding the heat sink 300 from local arching and scratching the display module 500, which would damage the display module 500.

[0063] refer to Figure 7 and Figure 8 In some embodiments, the portion of the heat sink 300 opposite to the hinge mechanism 100 is a transition portion 310. Figures 9 to 13 The transition portion 310 is fixedly connected to the reinforcing plate 400. In this way, the reinforcing plate 400 can be used to prevent the part of the heat sink 300 opposite to the hinge mechanism 100 from arching and deforming, thereby scratching the display module 500.

[0064] refer to Figure 2 In some embodiments, the hinge mechanism 100 includes a base 110, a first rotating assembly 120, and a second rotating assembly 130. The first rotating assembly 120 and the second rotating assembly 130 are respectively disposed on opposite sides of the base 110. A first frame 210 is connected to the first rotating assembly 120, and a second frame 220 is connected to the second rotating assembly 130. Thus, during the rotation of the first rotating assembly 120 relative to the base 110, the first rotating assembly 120 drives the first frame 210 to rotate relative to the base 110. During the rotation of the second rotating assembly 130 relative to the base 110, the second rotating assembly 130 drives the second frame 220 to rotate relative to the base 110.

[0065] refer to Figures 2 to 4 The display module 500 includes a first display section 510, a flexible bending section 520, and a second display section 530 connected in sequence. The first display section 510 is connected to the first frame 210, the second display section 530 is connected to the second frame 220, and the flexible bending section 520 is opposite to the hinge mechanism 100.

[0066] The first rotating assembly 120 includes a first support member 121, and the second rotating assembly 130 includes a second support member 131. When the electronic device 1 is in a folded state, the first support member 121, the base 110, and the second support member 131 form a receiving area 610 for receiving the flexible bending portion 520. Furthermore, when the electronic device 1 is in an unfolded state, the first support member 121 and the second support member 131 are located below the flexible bending portion 520. When the flexible bending portion 520 is touched, the first support member 121 and the second support member 131 support the flexible bending portion 520 to prevent it from collapsing.

[0067] In some embodiments, the first rotating assembly 120 further includes a first swing arm 122, a second swing arm, and a first connecting bracket. One side of the first swing arm 122 is rotatably connected to the base 110, and the other side is slidably connected to the first connecting bracket. One side of the second swing arm is rotatably connected to the base 110, and the other side is movably connected to the first connecting bracket. The first frame 210 is fixedly connected to the first connecting bracket. The first swing arm 122 is connected to the first support member 121.

[0068] The second rotating assembly 130 also includes a third swing arm 132, a fourth swing arm, and a second connecting bracket. One side of the third swing arm 132 is rotatably connected to the base 110, and the other side is slidably connected to the second connecting bracket. One side of the fourth swing arm is rotatably connected to the base 110, and the other side is movably connected to the second connecting bracket. The second frame 220 is fixedly connected to the second connecting bracket. The third swing arm 132 is connected to the second support member 131.

[0069] Thus, during the transition of the hinge mechanism 100 from the unfolded state to the folded state, the first swing arm 122 rotates relative to the base 110 to the upright state, the second swing arm rotates relative to the base 110 to the upright state, and the second swing arm drives the first connecting bracket to move away from the base relative to the first swing arm 122; the third swing arm 132 rotates relative to the base 110 to the upright state, the fourth swing arm rotates relative to the base 110 to the upright state, and the fourth swing arm drives the second connecting bracket to move away from the base relative to the third swing arm 132. Simultaneously, the first swing arm 122 drives the first support member 121 to rotate, and the third swing arm 132 drives the second support member 131 to rotate, so that the first support member 121, the base 110, and the second support member 131 form a teardrop-shaped receiving area 610. It should be noted that the second swing arm drives the first connecting bracket to move away from the base relative to the first swing arm 122, and the fourth swing arm drives the second connecting bracket to move away from the base relative to the third swing arm 132. This can increase the size of the accommodating area 610, thereby avoiding interference between the flexible bending part 520 and the first support member 121, the base 110, or the second support member 131.

[0070] It should also be noted that the specific structure of the hinge mechanism 100 can also refer to related technologies. In other words, the hinge mechanism 100 in this embodiment of the present invention can be a hinge mechanism in related technologies, and the specific structure of the hinge mechanism 100 in this embodiment of the present invention is not limited.

[0071] In some embodiments, the portion of the heat sink 300 facing the first support member 121 is fixedly connected to the first support member 121, and the portion of the heat sink 300 facing the second support member 131 is fixedly connected to the second support member 131. For example, the first support member 121 has a first adhesive layer on the side facing the heat sink 300, and the first support member 121 is bonded and fixed to the portion of the heat sink 300 facing the first support member 121 through the first adhesive layer. The second support member 131 has a second adhesive layer on the side facing the heat sink 300, and the second support member 131 is bonded and fixed to the portion of the heat sink 300 facing the second support member 131 through the second adhesive layer. In this way, by fixing the heat sink 300 to the first support member 121 and the second support member 131 respectively, misalignment of the heat sink 300 relative to the first support member 121 and the second support member 131 can be prevented.

[0072] refer to Figure 3 In some embodiments, a first clearance area 620 is formed between the first support member 121 and the first frame 210, and a second clearance area 630 is formed between the second support member 131 and the second frame 220. When the electronic device 1 is in the unfolded state, a first bend 320 is formed at the portion of the heat sink 300 opposite to the first clearance area 620, and the first bend 320 is at least partially accommodated in the first clearance area 620. A second bend 330 is formed at the portion of the heat sink 300 opposite to the second clearance area 630, and the second bend 330 is at least partially accommodated in the second clearance area 630.

[0073] In this way, by ensuring that when the electronic device 1 is in the unfolded state, the first bent portion 320 of the heat sink 300 is at least partially accommodated in the first clearance area 620, and the second bent portion 330 of the heat sink 300 is at least partially accommodated in the second clearance area 630, the first bent portion 320 is prevented from being lifted by the first frame 210, and the second bent portion 330 is prevented from being scratched by the second frame 220.

[0074] It should be noted that, when the electronic device 1 is in a folded state, the second swing arm drives the first connecting bracket to move away from the base relative to the first swing arm 122, and the fourth swing arm drives the second connecting bracket to move away from the base relative to the third swing arm 132. This causes the first frame 210 to move away from the base along with the first connecting bracket, and the second frame 220 to move away from the base along with the second connecting bracket. Furthermore, since the heat sink 300 is connected to the first frame 210 and the second frame 220 respectively, during the movement of the first frame 210 and the second frame 220 away from the base, the heat sink 300 can be "straightened," thereby making the first bent portion 320 and the second bent portion 330 of the heat sink 300 flat.

[0075] refer to Figure 3 It shows that, when the electronic device 1 is in the unfolded state, the first bent portion 320 of the heat sink 300 is accommodated in the first clearance area 620, and the second bent portion 330 of the heat sink 300 is accommodated in the second clearance area 630. (See reference) Figure 4 It shows that when the electronic device 1 is in a folded state, the first bend 320 and the second bend 330 of the heat sink 300 become flat.

[0076] refer to Figures 9 to 12 In some embodiments, the portion where the reinforcing sheet 400 connects to the heat sink 300 is a reinforcing connection portion 410, located between the first bending portion 320 and the second bending portion 330. In other words, the portion where the reinforcing connection portion 410 is located between the first bending portion 320 and the second bending portion 330 is connected to the heat sink 300. This avoids the reinforcing connection portion 410 from connecting directly to the first bending portion 320 and the second bending portion 330, thus preventing the first bending portion 320 and the second bending portion 330 from bending and deforming smoothly when the electronic device 1 is switched to the unfolded state.

[0077] refer to Figures 9 to 12 In some embodiments, the reinforcing piece 400 extends along the length of the hinge mechanism 100 from a position opposite one end of the hinge mechanism 100 to a position opposite the other end of the hinge mechanism 100.

[0078] refer to Figure 9 The reinforcing plate 400 is a complete plate, and the reinforcing plate 400 is opposite to the hinge mechanism 100.

[0079] refer to Figure 10 The reinforcing sheet 400 has a first hollow portion 420, which is offset from the reinforcing connection portion 410. In this way, by providing the first hollow portion 420 on the reinforcing sheet 400, the toughness of the reinforcing sheet 400 can be reduced, thereby reducing the force required to overcome the rebound force of the reinforcing sheet 400 during the folding of the electronic device 1.

[0080] refer to Figure 11 The reinforcing piece 400 includes a first body 400a and a second body 400b. The first body 400a and the second body 400b are spaced apart, with the first body 400a opposite to the first rotating assembly 120 and the second body 400b opposite to the second rotating assembly 130. By dividing the reinforcing piece 400 into the first body 400a and the second body 400b from the axial position of the hinge mechanism 100, the force required to overcome the rebound force of the reinforcing piece 400 during the folding of the electronic device 1 is reduced.

[0081] refer to Figure 12 The reinforcing sheet 400 is covered with a plurality of second hollow portions 430 arranged in an array. In this way, by providing the second hollow portions 430 on the reinforcing sheet 400, the toughness of the reinforcing sheet 400 is reduced, thereby reducing the force required to overcome the rebound force of the reinforcing sheet 400 when folding the electronic device 1.

[0082] refer to Figures 4 to 6 In some embodiments, the reinforcing sheet 400 is disposed on the side of the heat sink 300 facing the display module 500. A first anti-friction layer 710 is provided on the side of the reinforcing sheet 400 facing the display module 500. Exemplarily, the first anti-friction layer 710 is a Teflon layer. The Teflon layer is made of polytetrafluoroethylene (PTFE). Polytetrafluoroethylene is a high molecular weight polymer obtained by polymerization of tetrafluoroethylene as a monomer, and it has the characteristic of extremely low coefficient of friction.

[0083] Thus, since the reinforcing sheet 400 has a first anti-friction layer 710 on the side facing the display module 500, the display module 500 can slide relative to the first anti-friction layer 710 during the switching process between the folded state and the unfolded state of the electronic device 1, thereby avoiding the display module 500 from being damaged by scratching the reinforcing sheet 400.

[0084] refer to Figures 13 to 23 In some embodiments, the heat sink 300 includes a first portion 340 and a second portion 350. The area of ​​the top surface of the first portion 340 is larger than the area of ​​the top surface of the second portion 350. The first portion 340 is opposite to the first frame 210, and the second portion 350 is opposite to the second frame 220.

[0085] The portion of the heat sink 300 facing the first support member 121 is fixedly connected to the first support member 121, and the portion of the heat sink 300 facing the second support member 131 is slidably engaged with the second support member 131. Exemplarily, a first adhesive layer is provided on the side of the first support member 121 facing the heat sink 300, and the first support member 121 is bonded and fixed to the portion of the heat sink 300 facing the first support member 121 through the first adhesive layer. The second support member 131 is not fixedly connected to the heat sink 300. During the switching between the unfolded state and the folded state of the electronic device 1, the first portion 340 is fixed relative to the first frame 210, the portion of the heat sink 300 facing the second support member 131 slides relative to the second support member 131, and the second portion 350 of the heat sink 300 slides relative to the second frame 220.

[0086] Thus, during the switching between the unfolded and folded states of the electronic device 1, the portion of the heat sink 300 facing the second support member 131 slides relative to the second support member 131, and the second portion 350 of the heat sink 300 slides relative to the second frame 220. Therefore, referring to... Figure 15 , Figure 16 , Figure 3 and Figure 4 The heat sink 300 will not bulge out to form the first bend 320 and the second bend 330. Therefore, it is unnecessary to set the first clearance area 620 and the second clearance area 630.

[0087] refer to Figure 16 , Figure 22 and Figure 23 For example, the first adhesive layer 820 is provided on the portion of the heat sink 300 facing the first support member 121. The portion of the heat sink 300 facing the first support member 121 is bonded and fixed to the first support member 121 by the first adhesive layer 820.

[0088] refer to Figures 16 to 18 In some embodiments, the reinforcing sheet 400 is disposed on the side of the heat sink 300 facing the second support member 131. A second anti-friction layer 720 is provided on the side of the reinforcing sheet 400 facing the second support member 131. Exemplarily, the second anti-friction layer 720 is a Teflon layer. Thus, because the reinforcing sheet 400 has the second anti-friction layer 720 on the side facing the second support member 131, the sliding friction resistance between the reinforcing sheet 400 and the second support member 131 can be reduced. Furthermore, during the switching between the folded and unfolded states of the electronic device 1, the portion of the heat sink 300 facing the second support member 131 can slide smoothly relative to the second support member 131 along with the reinforcing sheet 400.

[0089] refer to Figures 20 to 23 In some embodiments, the second portion 350 and the reinforcing piece 400 are fixedly connected. In this way, by fixing the second portion 350 and the reinforcing piece 400 together, the strength of the second portion 350 can be improved, so as to prevent arching during the sliding of the second portion 350 relative to the second support member 131.

[0090] refer to Figures 20 to 23 For example, the electronic device 1 also includes a third adhesive layer 810. The reinforcing sheet 400 is bonded and fixed to the transition portion 310 and the second portion 350 of the heat sink 300 via the third adhesive layer 810.
