As shown in fig. 1, a middle frame assembly 10 of an electronic device 100 according to an embodiment of the present application includes: the middle frame body 1 and the heat dissipation component 2.
Specifically, as shown in fig. 1, the middle frame body 1 includes a first frame body 11 and a second frame body 12 connected to each other, a rotating shaft 13 is provided between the first frame body 11 and the second frame body 12, and the first frame body 11 and the second frame body 12 are rotatable about the rotating shaft 13 to switch between an unfolded state and a folded state.

As can be seen, in the middle frame assembly 10 according to the embodiment of the present invention, the heat dissipation plate 21 is not fixed to the middle frame body 1, but is connected to the first heat transfer plate 22 and the second heat transfer plate 23, respectively, and the second heat transfer plate 23 is movable relative to the second frame body 12, so that a part of the heat dissipation plate 21 is movable relative to the middle frame body 1. It can be understood that, when the middle frame body 1 is switched from the unfolded state to the folded state under the action of external force, the heat dissipation plate 21 and the flexible screen 20 of the electronic device 100 are gradually folded between the first frame body 11 and the second frame body 12, and at this time, the heat dissipation plate 21 is located outside the flexible screen 20, so that during the folding process, the heat dissipation plate 21 is subjected to a tensile stress towards the folding center, because the second heat transfer plate 23 is connected with the heat dissipation plate 21, under the action of the tensile stress, the heat dissipation plate 21 drives the second heat transfer plate 23 to move from the second position to the first position, and further the heat dissipation plate 21 moves towards the folding center relative to the second frame body 12, thereby ensuring the folding reliability of the flexible screen 20, effectively avoiding the arching of the flexible screen 20 during the folding process, effectively solving the problem of cracking of the flexible screen 20, and improving the reliability of the electronic device 100, which is beneficial to extending the service life of the electronic device 100.
Meanwhile, it can be seen that, because the first heat transfer plate 22 is disposed on the first frame 11, the second heat transfer plate 23 is disposed on the second frame 12, and the heat dissipation plate 21 is connected to the first heat transfer plate 22 and the second heat transfer plate 23, respectively, it can be understood that the heat dissipation plate 21 extends from the first frame 11 to the second frame 12, thereby improving the heat dissipation effect of the whole electronic device 100, making the heat conduction and dissipation of the electronic device 100 more uniform, avoiding heat concentration, improving the reliability of the middle frame assembly 10 and the electronic device 100, and being beneficial to prolonging the service life of the electronic device 100.
According to the middle frame assembly 10 of the electronic device 100 of the embodiment of the present application, by making the heat dissipation assembly 2 include the heat dissipation plate 21, the first heat transfer plate 22 and the second heat transfer plate 23 are disposed at an interval, the first heat transfer plate 22 is fixed on the first frame 11, the second heat transfer plate 23 is disposed on the second frame 12 and is movable between the first position and the second position relative to the second frame 12, the second position is located between the first heat transfer plate 22 and the first position, the heat dissipation plate 21 is located on one side of the first heat transfer plate 22 and the second heat transfer plate 23 away from the middle frame body 1 and is respectively connected with the first heat transfer plate 22 and the second heat transfer plate 23, and when the middle frame body 1 is switched from the unfolded state to the folded state, the heat dissipation plate 21 is gradually folded between the first frame 11 and the second frame 12. Therefore, arching of the flexible screen 20 in the folding process is effectively avoided, the problem of cracking of the flexible screen 20 is effectively solved, the heat dissipation effect of the whole electronic device 100 can be improved, heat conduction and heat dissipation of the electronic device 100 are more uniform, heat concentration is avoided, the reliability of the middle frame assembly 10 and the reliability of the electronic device 100 are improved, and the service life of the electronic device 100 is prolonged.
As shown in fig. 1 to 3, according to some embodiments of the present disclosure, the opposite side walls of the second frame 12 are respectively provided with a sliding groove 121, the extending direction of the sliding groove 121 is the same as the extending direction of the second frame 12, and the opposite ends of the second heat transfer plate 23 respectively extend into the corresponding sliding grooves 121 and are slidable in the sliding grooves 121. It is thus understood that the fitting manner of the second heat transfer plate 23 and the second housing 12 is simple and easy to assemble, and the reliability of the movement of the second heat transfer plate 23 relative to the second housing 12 can be ensured. At the same time, the reliability of the second heat transfer plate 23 provided in the second housing 12 can be improved to some extent, and the second heat transfer plate 23 can be prevented from coming off the second housing 12 to some extent. Thereby improving the reliability of the middle frame assembly 10.
As shown in fig. 1, according to some embodiments of the present application, the middle frame assembly 10 further includes an elastic member 3, the elastic member 3 is connected to the second heat transfer plate 23, and the second heat transfer plate 23 gradually presses the elastic member 3 when the middle frame body 1 is switched from the unfolded state to the folded state; in the unfolded state, the resilient member 3 normally drives the second heat transfer plate 23 in the first position.
As is known, when the middle frame body 1 is switched from the expanded state to the folded state under the action of an external force, the second heat transfer plate 23 moves from the second position to the first position, so that the second heat transfer plate 23 gradually presses the elastic member 3, so that the elastic member 3 has a certain elastic force on the second heat transfer plate 23, and the direction of the elastic force is toward the first position, so that in the expanded state, the elastic force of the elastic member 3 drives the second heat transfer plate 23 to move from the second position to the first position. The heat dissipation plate 21 is connected to the second heat transfer plate 23, and thus, the second heat transfer plate 23 moves relative to the second frame 12, and returns to the state before being folded. This also prevents the heat dissipation plate 21 from being returned to its original position to a certain extent, which may affect the expansion of the flexible panel 20. For example, the heat dissipation plate 21 is a graphite sheet, and the graphite sheet has no elasticity, and cannot automatically return to the original position after being folded, so that the arrangement of the elastic member 3 in the present application can effectively solve the return problem of the heat dissipation plate 21 from the folded state to the unfolded state, and avoid the arching of the flexible screen 20, thereby improving the reliability of the electronic device 100.
As shown in fig. 4 and 5, in some embodiments of the present application, both ends of the elastic member 3 are connected to the second heat transfer plate 23 and the second frame body 12, respectively. Thereby making the installation of the elastic member 3 convenient and being beneficial to reducing the occupied space of the structure for installing the elastic member 3.
As shown in fig. 4 and 5, in some embodiments of the present application, a fixing portion 231 is provided on one end of the second heat transfer plate 23 adjacent to the first heat transfer plate 22, and one end of the elastic member 3 is connected to the fixing portion 231 and the other end is connected to one end of the second frame 12 adjacent to the second frame 12. Therefore, when the middle frame body 1 is switched from the unfolding state to the folding state, the second heat transfer plate 23 can extrude the elastic piece 3, and further, when the middle frame body 1 is switched from the folding state to the unfolding state, the heat dissipation plate 21 can return to the original position, the flexible screen 20 is prevented from arching, the reliability of the middle frame assembly 10 is improved, and the reliability of the electronic device 100 is improved.
As shown in fig. 5, in some embodiments of the present application, the fixing portion 231 is disposed at the bottom of the second heat transfer plate 23, the bottom wall of the second frame 12 is provided with a fitting hole 122, a portion of the fixing portion 231 passes through the fitting hole 122 to be fitted with the elastic member 3, and the fixing portion 231 is movable relative to the fitting hole 122. Here, the bottom refers to a portion of the second heat transfer plate 23 close to the second frame 12, and the bottom wall refers to a wall of the second frame 12 away from the heat sink 21. It can be seen that the elastic member 3 is installed below the second heat transfer plate 23, and the elastic member 3 can be spaced apart from the moving path of the second heat transfer plate 23, ensuring the reliability of the movement of the second heat transfer plate 23. It will also be appreciated that the fixing portion 231 is movable within the mating hole 122 when the second heat transfer plate 23 is moved between the first and second positions.
As shown in fig. 1, in some embodiments of the present disclosure, the fixing portions 231 are disposed at intervals, the elastic members 3 are disposed at intervals, and the plurality of elastic members 3 and the plurality of fixing portions 231 are disposed in a one-to-one correspondence. This can improve the reliability of the second heat transfer plate 23 returning to the original position when the folded state is switched to the unfolded state. It can also be understood that even if one of the plurality of elastic members 3 fails, another portion of the non-failed elastic member 3 can still be used to drive the second driving plate to move toward the first position to return to the original position. Thereby prolonging the service life of the middle frame assembly 10 and the electronic device 100 to a certain extent and reducing the maintenance frequency of the electronic device 100.
In some embodiments of the present application, the elastic member 3 is a spring. Therefore, the elastic part 3 can have reliable elastic force, and meanwhile, the elastic part 3 is simple in structure, wide in source, low in cost and convenient to install. Of course, the elastic member 3 may be other structural members as long as the reliability of the elastic member 3 is ensured.
According to some embodiments of the present application, at least one of the heat dissipation plate 21, the first heat transfer plate 22, and the second heat transfer plate 23 is a piece of graphite material. Graphite is known to be chemically stable and insoluble in water, dilute acids, dilute bases and organic solvents. Has reliable heat conduction and dissipation effects, so that the heat dissipation effect of the electronic device 100 can be ensured. Needless to say, the material of the heat dissipation plate 21, the first heat transfer plate 22, and the second heat transfer plate 23 is not limited to this, and may be other materials as long as heat can be efficiently transferred and dissipated.
