Referring to fig. 4, in the present embodiment, the first air duct 111 and the second air duct 112 are provided with a first sub-frame 113 at an interval, the first air duct 111 has a first air inlet 1111 and a first air outlet 1112 facing away from each other, the second air duct 112 has a second air inlet 1121 and a second air outlet 1122 communicating with each other, wherein the first air inlet 1111 and the second air outlet 1122 are disposed on the outer side 118, the first air outlet 1112 and the second air inlet 1121 are disposed on the inner side 117, the first air outlet 1112 can be communicated with the first heat dissipation hole 201, the second air inlet 1121 can be communicated with the second heat dissipation hole 202, and it should be noted that the air inlet refers to an air inlet into which air flows; the air outlet refers to an air outlet through which air flow of the air inlet flows out. It can be understood that, when the protection case 100 is disposed on the mobile terminal 200, the first air outlet 1112 may be communicated with the first heat dissipation hole 201, the second air inlet 1121 may be communicated with the second heat dissipation hole 202, external air flow may flow into the first heat dissipation hole 201 from the first air outlet 1112 through the first air inlet 1111, air flow flowing into the mobile terminal 200 may flow into the second air inlet 1121 through the second heat dissipation hole 202 and flow out through the second air outlet 1122, thereby achieving circulation of air flow inside the mobile terminal 200, heat generated inside the mobile terminal 200 may be rapidly taken away by the circulating air flow, and further achieving a heat dissipation effect. In addition, the wall surface in the first air passage 111 and the wall surface of the second air passage 112 may be provided with smooth surfaces, which may reduce the flow resistance of the air flow.

In this embodiment, the distance between the first air duct 111 and the second air duct 112 may be adjusted according to actual requirements, wherein the distance between the first air duct 111 and the second air duct 112 may be greater than 1/3 or 1/2 of the overall length of the first sub-frame 113, for example, the first air duct 111 and the second air duct 112 may be respectively disposed at two ends of the first sub-frame 113, specifically, the first air duct 111 may be disposed at one end of the first sub-frame 113 close to the third sub-frame 115, and the second air duct 111 may be disposed at one end of the first sub-frame 113 close to the fourth sub-frame. When the distance between the first air duct 111 and the second air duct 112 is small, for example: the air flow entering the mobile terminal 200 through the first air duct 111 can rapidly flow out through the second air duct 112, so that the path of the air flow flowing through the mobile terminal 200 can be reduced, the flow rate of the air flow cannot be reduced in a short distance, the air flow can be kept at a high flow rate in the mobile terminal 200, and rapid circulation heat dissipation can be realized; when the distance between the first air duct 111 and the second air duct 112 is large, the range of the air flow flowing inside the mobile terminal 200 is increased due to the long path of the air flow flowing inside the mobile terminal 200, and further, the air flow can take away more heat inside the mobile terminal 200 during the flowing process.

In some embodiments, the first duct 111 and the second duct 112 may be disposed at any position of the bezel 110, for example, the first duct 111 and the second duct 112 may be disposed at other sub-bezels.

In some embodiments, the first air inlet 1111 and the second air outlet 1122 can also be disposed on the inner side 117, and the first air outlet 1112 and the second air inlet 1121 are disposed on the outer side 118.

In some embodiments, as shown in fig. 5, the first air duct 111 may be disposed on the first sub-frame 113, and the second air duct 112 may be disposed on the second sub-frame 114, wherein the first air outlet 1112 may be opposite to the second air inlet 1121, and it should be noted that the opposite means that an axis of the first air outlet 1112 substantially coincides with an axis of the second air inlet 1121. It is understood that the air flow flowing out of the first air outlet 1112 can flow into the second air inlet 1121 substantially along the axial direction of the first air outlet 1112. By arranging the first air outlet 1112 and the second air inlet 1121 oppositely, the air flow entering the mobile terminal 200 from the first air outlet 1112 can directly flow to the second air inlet 1121, so that the path through which the air flow flows can be reduced, the air flow is prevented from being excessively blocked by electronic devices inside the mobile terminal 200, and the flow rate of the air flow is prevented from being slowed down, so that the air flow inside the mobile terminal 200 can rapidly flow into the second air inlet 1121 and rapidly flow out from the second air outlet 1122, and thus, the heat generated inside the mobile terminal 200 can be rapidly taken away.

In addition, in some embodiments, the first air duct 111 and the second air duct 112 may be arranged in a staggered manner. For example: the first air duct 111 may be disposed at one end of the first sub-frame 113 close to the third sub-frame 115, and the second air duct 112 may be disposed at one end of the second sub-frame 114 close to the fourth sub-frame 116; for another example: the first air duct 111 may be disposed on the first sub-frame 113, and the second air duct 112 may be disposed on the fourth sub-frame 116.

In some embodiments, as shown in fig. 4, the inner diameter of the first air inlet 1111 is greater than the inner diameter of the first air outlet 1112, so that more air from the outside can enter the first air inlet 1111, when the air flow in the first air duct 111 passes through the first air outlet 1112, because the inner diameter of the first air outlet 1112 is smaller than the inner diameter of the first air inlet 1111, when the air flow with the same flow rate passes through the air outlet with a smaller aperture size, the flow rate of the air flow is faster, so that the air flow flowing out through the first air outlet 1112 can flow into the mobile terminal 200 at a faster flow rate, and thus the air flow can circulate fast in the mobile terminal 200; in addition, the inner diameter of the second air inlet 1121 is larger than the inner diameter of the second air outlet 1122, so that the air flow in the mobile terminal 200 can be more collected into the second air inlet 1121, so that the air flow can rapidly flow out of the second air duct 112 and take away more heat.

In addition, in some embodiments, the inner diameter of the first intake 1111 may also be smaller than or equal to the inner diameter of the first outtake port 1112; the inner diameter of the second wind inlet 1121 may also be smaller than or equal to the inner diameter of the second wind outlet 1122.

Specifically, the first heat dissipation fan 121 drives the air to form an airflow flowing from the first air inlet 1111 and flowing out toward the first air outlet 1112 during the rotation process; the second heat dissipation fan 131 drives the air to form an airflow flowing from the second air inlet 1121 and flowing out toward the second air outlet 1122 during the rotation process, so that the flow direction of the airflow flowing through the first air channel 111 is opposite to the flow direction of the airflow flowing through the second air channel 112. In this embodiment, the number of the first heat dissipation fan 121 and the second heat dissipation fan 131 and the size of the blades are not limited herein, and for example, the number of the blades may be 3, 5, or any other number.

In addition, in some embodiments, the rotation direction of the first heat dissipation fan 121 and the rotation direction of the second heat dissipation fan 131 may also be the same, for example, the first heat dissipation fan 121 may be disposed on the first sub-frame 113, and the second heat dissipation fan 131 may be disposed on the second sub-frame 114.

The first heat dissipation device 120 and the second heat dissipation device 130 may be piezoelectric ceramic fans, micro axial fans, blowers, air pumps, and other devices, which are not particularly limited herein, and only need to be devices for driving air to circulate. For example, the first and second heat dissipation fans 121 and 131 may be replaced by a blower, an air pump, or the like.

In some embodiments, a fixing portion for fixing the first heat dissipation fan 121 may be disposed in the first air duct 111, wherein the fixing portion is fixed to the frame 110, the fixing portion may be provided with a rotating shaft hole, and the rotating shaft of the first heat dissipation fan 121 may be rotatably mounted in the rotating shaft hole, so that the first heat dissipation fan 121 may rotate with the rotating shaft hole as a rotation center; a corresponding second heat dissipation fan 131 may also be mounted in the second air duct 112 in the same manner.

In some embodiments, as shown in fig. 6, the protective case 100 further includes a heat dissipation plug 140, wherein the first air duct 111 and the second air duct 112 may be disposed inside the heat dissipation plug 140, and the heat dissipation plug 140 may be detachably mounted on the frame 110, for example, the frame 110 may be provided with a plug hole 119 for mounting the heat dissipation plug 140, the plug hole 119 may have a size corresponding to that of the heat dissipation plug 140, the plug hole 119 penetrates through the frame 110, and the heat dissipation plug 140 may be mounted on the frame 110 via the plug hole 119, thereby achieving detachable mounting. Wherein the shape of the insertion hole 119 may be configured as a circle, an ellipse, a waist circle, a polygon or any other shape. During assembly, the heat dissipation plug-in 140 can be directly embedded into the insertion hole 119 to be fixed to the frame 110, and the heat dissipation plug-in 140 and the frame 110 can be fixed in a clamping manner, an interference embedding manner or a magnetic adsorption manner, for example, a magnetic member can be arranged in the insertion hole 119, a magnet matched with the magnetic member can be arranged on the surface of the heat dissipation plug-in 140, and when the heat dissipation plug-in 140 is inserted into the insertion hole 119, the heat dissipation plug-in 140 can be fixed in the insertion hole 119 through magnetic attraction between the two, or the surface of the heat dissipation plug-in 140 can be made of a metal material, that is.

The first card 141 and the second card 142 are detachably assembled, for example, the first card 141 and the second card 142 may be fixed by clamping, magnetic attraction, or the like, or both may be fixed by a connector. During assembly, the first plug-in unit 141 and the second plug-in unit 142 may be assembled and fixed in advance, and then the first plug-in unit 141 and the second plug-in unit 142 are simultaneously inserted into the insertion hole 119 for assembly.

In some embodiments, the first insert 141 and the second insert 142 may be provided as an integral structure, for example, they may be integrally formed by integral molding, welding, 3D printing, etc.

In some embodiments, the number of the jacks 119 may be two, two jacks 119 may be disposed at any position of the frame 110, and the first inserts 141 and the second inserts 142 correspond to the jacks 119 in a one-to-one manner, and both inserts may be respectively assembled in different jacks 119.

Further, referring to fig. 8 and 9, the heat dissipating insert 140 further includes a sealing ring 143, and at least one of the first insert 141 and the second insert 142 is provided with an annular groove 1413, it is understood that only one of the first insert 141 and the second insert 142 may be provided with the annular groove 1413, or both of the first insert 141 and the second insert 142 may be provided with the annular groove 1413, and the sealing ring 143 is embedded in the annular groove 1413 and at least partially protrudes from the annular groove 1413. By arranging the sealing ring 143 in the annular groove 1413, when the heat dissipation plug-in 140 is inserted into the heat dissipation hole of the mobile terminal 200, since a certain assembly gap may exist between the heat dissipation plug-in 140 and the heat dissipation hole of the mobile terminal 200, the sealing ring 143 can be filled into the assembly gap, so that the sealing property between the heat dissipation plug-in 140 and the mobile terminal 200 is better, thereby preventing the air flow from leaking out from the assembly gap between the heat dissipation plug-in 140 and the mobile terminal 200, and further ensuring that a sufficient amount of air flow flows into the heat dissipation hole of the mobile terminal 200 from the heat dissipation plug.

Through the arrangement of the heat dissipation plug-in 140, the first plug-in 141 and the second plug-in 142 can be separated from each other, if the heat dissipation plug-in 140 is damaged, a user can directly and independently replace the heat dissipation plug-in 140 without replacing the whole protection shell 100, and in addition, when one of the first plug-in 141 and the second plug-in 142 is damaged, only one of the first plug-in 141 and the second plug-in 142 needs to be replaced, so that the user can replace the heat dissipation plug-in and the cost is saved.

In some embodiments, dust screens may be disposed in the first air duct 111 and the second air duct 112, wherein the dust screens may be respectively fixed in the first air duct 111 and the second air duct 112, so as to achieve a dust-proof effect, reduce external impurities from entering the mobile terminal 200, and prevent the mobile terminal 200 from being damaged.

Referring to fig. 10, in the present embodiment, the protective case 100 is provided with a control module 150, the control module 150 is electrically connected to the first heat dissipation device 120 and the second heat dissipation device 130, and is in signal connection with a temperature sensor of the mobile terminal 200, and the control module 150 is configured to control the first heat dissipation device 120 or the second heat dissipation device 130 to work or stop working according to temperature information sent by the temperature sensor, where the temperature information refers to a temperature inside the mobile terminal 200 detected by the temperature sensor or a temperature of the detected electronic component.

In some embodiments, for example, when the temperature sensor detects that the internal temperature of the mobile terminal 200 increases, when the control module 150 receives the temperature value transmitted by the temperature sensor and determines whether the temperature value is greater than a preset temperature value, if the temperature value is greater than the preset temperature value, the control module 150 may control the first heat dissipation device 120 or the second heat dissipation device 130 to operate, for example, the control module 150 may control the first heat dissipation device 120 and the second heat dissipation device 130 to be simultaneously activated; the control module 150 may control the rotational speed of the first heat dissipation device 120 and the rotational speed of the second heat dissipation device 130.
