[0045] The air outlet of the detachable fan module 500 faces the side where the main board 600 is located. The detachable fan module 500 is used to discharge air toward the side of the main board 600.

[0046] See also Figure 3 and Figure 4 When the detachable fan module 500 is installed in the receiving cavity 611 of the installation frame 610, the air outlet of the detachable fan module 500 faces the first opening 616. The air outlet of the detachable fan module 500 blows air toward the mainboard 600 through the first opening 616, thereby increasing the heat dissipation effect of the heating element 640 on the mainboard 600.

[0047] The fixing mechanism 620 is disposed on the side wall of the receiving cavity 611. The fixing mechanism 620 is used to abut against the side wall of the detachable fan module 500 when the detachable fan module 500 is in the installed state, so that the detachable fan module 500 is in a stable installed state.

[0048] For further information, see Figure 4 The mounting frame 610 further includes a second side panel 617, a third side panel 618 and a fourth side panel 619.

[0049] The fixing mechanism 620 is disposed on the second side panel 617 and / or the fourth side panel 619 in the receiving cavity 611. The fixing mechanism 620 is used to abut against the detachable fan module 500 when the detachable fan module 500 is in the receiving cavity 611, so that the detachable fan module 500 is fixed in the receiving cavity 611.

[0050] Optionally, the number of the fixing mechanism 620 is one, and one fixing mechanism 620 is disposed on the second side panel 617 or the fourth side panel 619 .

[0051] For optional reference, see Figure 3 and Figure 4 There are two fixing mechanisms 620, and the two fixing mechanisms 620 are respectively arranged on the second side panel 617 and the fourth side panel 619 to improve the firmness of the detachable fan module 500 when it is in the installed state.

[0052] See also Figure 5 The pushing mechanism 630 includes a pushing portion 631 and a rotating portion 632 which are bent and connected.

[0053] See also Figure 5 The push portion 631 is disposed on one side of the detachable fan module 500. Optionally, the push portion 631 is disposed along the second side panel 617. Further, the push portion 631 is disposed between the second side panel 617 and the housing of the detachable fan module 500.

[0054] See also Figure 5 , the rotating portion 632 is arranged on a side of the detachable fan module 500 away from the through hole 612. The rotating portion 632 is arranged along the third side panel 618. The pushing portion 631 is used to drive the rotating portion 632 to rotate under the pressure toward the third side panel 618, so as to push the detachable fan module 500 out through the through hole 612. Specifically, when the pushing portion 631 moves toward the third side panel 618, the pushing portion 631 drives one end of the rotating portion 632 to rotate, and the other end of the rotating portion 632 pushes the detachable fan module 500 to move toward the through hole 612, and a part of the detachable fan module 500 extends out of the mounting frame 610, so as to facilitate the removal of the detachable fan module 500 for cleaning or replacement.

[0055] The present application provides a mobile terminal 1000, which includes a mainboard 600, a mounting frame 610, a detachable fan module 500, a fixing mechanism 620 and a pushing mechanism 630. The mainboard 600 is provided with a heating element 640. The mounting frame 610 includes a receiving cavity 611 and a through hole 612 connected to the receiving cavity 611. The detachable fan module 500 is detachably installed in the receiving cavity 611 of the mounting frame 610 through the through hole 612. The air outlet of the detachable fan module 500 faces the side where the mainboard 600 is located. The detachable fan module 500 is used to discharge air toward the side of the mainboard 600 to quickly dissipate the heat of the heating element 640 on the mainboard 600. The fixing mechanism 620 is arranged on the side wall of the receiving cavity 611. The fixing mechanism 620 is used to abut against the side wall of the detachable fan module 500 when the detachable fan module 500 is in the installed state, so as to lock the detachable fan module 500 in the installation frame 610; the pushing mechanism 630 includes a pushing portion 631 and a rotating portion 632 that are bent and connected, the pushing portion 631 is arranged on one side of the detachable fan module 500, and the rotating portion 632 is arranged on the side of the detachable fan module 500 away from the through hole 612; the pushing portion 631 is used to drive the rotating portion 632 to rotate under pressure, so as to push the detachable fan module 500 out through the through hole 612, so as to facilitate the disassembly of the detachable fan module 500 for cleaning or replacement, thereby improving the heat dissipation effect and facilitating use and cleaning.

[0056] Optional, see Figure 4 The detachable fan module 500 includes a fan cover 501, a fan housing 502, and a fan body 505 disposed in the fan housing 502. The fan cover 501 is connected to one side of the fan housing 502. When the detachable fan module 500 is in the installed state, the fan cover 501 is disposed in the through hole 612. Optionally, the through hole 612 and the first frame hole 325 are the same hole.

[0057] The fan cover plate 501 is an integral structure with the fan housing 502. Further, the fan cover plate 501 and the fan housing 502 are arranged along the width direction, and the orthographic projection of the fan cover plate 501 in the width direction can cover the orthographic projection of the fan housing 502 in the width direction.

[0058] Further, the dimension of the fan cover plate 501 in the thickness direction is greater than the dimension of the fan housing 502 in the thickness direction. The dimension of the fan cover plate 501 in the length direction is greater than the dimension of the fan housing 502 in the length direction.

[0059] See also Figure 4 , the connection between the fan cover 501 and the fan housing 502 forms a first step surface facing the third side panel 618. The hole wall of the first frame hole 325 and the cavity wall of the receiving cavity 611 form a second step surface facing away from the third side panel 618. The first step surface is adapted to the second step surface. When the detachable fan module 500 is arranged in the receiving cavity 611, the fan cover 501 abuts against the second step surface. In other words, the second step surface is the limiting surface when the detachable fan module 500 is in the installed state. Furthermore, when the fan cover 501 abuts against the second step surface, the surface of the fan cover 501 is flush with the surface of the first side frame 322, so as to improve the consistency of the appearance morphology between the surface of the fan cover 501 and the surface of the first side frame 322.

[0060] Optional, see Figure 5 A first limiting portion 503 and a second limiting portion 504 are respectively provided on both sides of the fan housing 502 along the width direction.

[0061] See also Figure 5 Correspondingly, the fixing mechanism 620 includes a first fixing member 621 and a second fixing member 622 .

[0062] See also Figure 5 A portion of the first fixing member 621 is fixed to the first side wall of the accommodating cavity 611, and another portion of the first fixing member 621 elastically abuts against the first limiting portion 503. The detachable fan module 500 is fixed in the installation frame 610 by fixing one side of the fan housing 502, so that the detachable fan module 500 is in an installed state.

[0063] See also Figure 5 A portion of the second fixing member 622 is fixed to the second side wall of the accommodating cavity 611, and another portion of the second fixing member 622 elastically abuts against the second limiting portion 504. The detachable fan module 500 is fixed in the installation frame 610 by fixing the other side of the fan housing 502, so that the detachable fan module 500 is in an installed state.

[0064] The detachable fan module 500 is fixed in the mounting frame 610 by fixing the fan housing 502 on both sides along the width direction, so that the detachable fan module 500 is stably installed in the accommodating cavity 611, thereby reducing the risk of the detachable fan module 500 falling out of the mounting frame 610 due to collision, falling, etc. of the mobile terminal 1000, thereby improving the stability and reliability of the mobile terminal 1000.

[0065] Further optionally, the first limiting portion 503 is a first limiting groove (labeled 503 in the figure). The first limiting groove is a limiting groove provided on a side of the fan housing 502 facing the top frame 321 .

[0066] The first fixing member 621 is a first elastic member (labeled 621 in the figure).

[0067] Two ends of the first elastic member are respectively fixedly connected to the first side wall of the receiving cavity 611 , and a middle portion of the first elastic member protrudes toward the location of the first limiting groove and is engaged with the first limiting groove.

[0068] Specifically, the first elastic member is a bent spring sheet or elastic arm. For example, the first elastic member is a first elastic arm. Both ends of the first elastic arm are respectively fixedly connected to the first side wall (the second side panel 617) of the receiving cavity 611, and the middle portion of the first elastic arm protrudes toward the location of the first limiting groove (towards the fourth side panel 619) and is engaged with the first limiting groove.

[0069] Further optionally, the second limiting portion 504 is a second limiting groove (labeled 504 in the figure). The second fixing member 622 is a second elastic member (labeled 622 in the figure). Both ends of the second elastic member are respectively fixedly connected to the second side wall of the receiving cavity 611. The middle part of the second elastic member protrudes toward the position of the second limiting groove and is engaged with the second limiting groove.

[0070] Specifically, the second elastic member is a bent spring sheet or elastic arm. For example, the second elastic member is a second elastic arm. Both ends of the second elastic arm are respectively fixedly connected to the second side wall (fourth side panel 619) of the receiving cavity 611, and the middle portion of the second elastic arm protrudes toward the location of the second limiting groove (towards the second side panel 617) and is engaged with the second limiting groove.

[0071] For further optional information, see Figure 6 and Figure 7 The first elastic member (such as the aforementioned first elastic arm) includes a first inclined arm 6211, a first abutting arm 6212, a second abutting arm 6213, a first guide arm 6214 and a second inclined arm 6215 which are bent and connected in sequence.

[0072] One end of the first inclined arm 6211 away from the first abutting arm 6212 is fixedly connected to the first side wall of the receiving cavity 611 (close to the third side panel 618). The first inclined arm 6211 is connected to one end of the first abutting arm 6212 and is spaced from the first side wall of the receiving cavity 611. In other words, one end of the first inclined arm 6211 is fixedly connected to the position of the second side panel 617 close to the third side panel 618. The other end of the first inclined arm 6211 extends in a direction gradually away from the second side panel 617 and away from the third side panel 618, and the extension direction of the first inclined arm 6211 is inclined to both the X direction and the Y direction. Further, the angle between the first inclined arm 6211 and the second side panel 617 is smaller than the angle between the first inclined arm 6211 and the third side panel 618. Further optionally, the angle between the first inclined arm 6211 and the second side panel 617 is about 15° to 40°. If the angle between the first inclined arm 6211 and the second side panel 617 is too small, the elastic deformation size of the first elastic member in the Y direction will be small; if the angle between the first inclined arm 6211 and the second side panel 617 is too large, the first elastic member will occupy a larger space in the Y direction, and the size of the installation frame 610 in the Y direction will be larger, thus resulting in the installation frame 610 occupying a larger space.

[0073] The first abutment arm 6212 and the second abutment arm 6213 are used to engage with the groove wall of the first limiting groove when the detachable fan module 500 is in the installed state.

[0074] Specifically, the first abutting arm 6212 is bent compared to the first inclined arm 6211. The angle between the first abutting arm 6212 and the second side panel 617 is greater than the angle between the first inclined arm 6211 and the second side panel 617, and the angle between the first abutting arm 6212 and the second side panel 617 is less than 90°.

[0075] Optional, see Figure 6 and Figure 7 The groove wall of the first limiting groove includes a first groove wall 5031, a second groove wall 5032, and a third groove wall 5033 along the X direction. The first groove wall 5031 is inclined compared to the X direction, and the first abutting arm 6212 is used to be arranged in the first limiting groove and abut the first groove wall 5031 to limit the detachable fan module 500 in the X direction.

[0076] The second abutting arm 6213 is bent compared to the first abutting arm 6212. The angle between the second abutting arm 6213 and the second side panel 617 is smaller than the angle between the first abutting arm 6212 and the second side panel 617. Further optionally, the angle between the second slot wall 5032 and the second side panel 617 is 0° or close to 0°, the second abutting arm 6213 is used to be arranged in the first limiting slot and abut the second slot wall 5032, and the angle between the second abutting arm 6213 and the second side panel 617 is 0° or close to 0°, so that the force of the second abutting arm 6213 on the fan housing 502 is substantially along the Y direction, so as to limit the detachable fan module 500 in the Y direction.

[0077] The first guide arm 6214 is used to guide the detachable fan module 500 when it is inserted into the receiving cavity 611 .

[0078] Specifically, the first guide arm 6214 is bent compared to the second abutting arm 6213. The first guide arm 6214 extends from one end of the second abutting arm 6213 toward a direction close to the second side panel 617 and gradually away from the third side panel 618.

[0079] The angle between the first guide arm 6214 and the second side panel 617 is greater than the angle between the first inclined arm 6211 and the second side panel 617, and the angle between the first abutment arm 6212 and the second side panel 617 is smaller than the angle between the first abutment arm 6212 and the second side panel 617. During the process of inserting the detachable fan module 500 into the accommodating cavity 611, the first elastic member has sufficient deformation space and the inclination angle of the first guide arm 6214 is not too steep, thereby gradually guiding the detachable fan module 500 into the accommodating cavity 611.

[0080] Optionally, the third groove wall 5033 is inclined relative to the X direction, and the angle between the third groove wall 5033 and the second side panel 617 is smaller than the angle between the first guide arm 6214 and the second side panel 617. When the detachable fan module 500 is in the installed state, the third groove wall 5033 and the first guide arm 6214 are spaced apart. In the process of the detachable fan module 500 being pushed out, the third groove wall 5033 can serve as a guide groove wall for the detachable fan module 500 to be moved out. The angle between the third groove wall 5033 and the second side panel 617 is smaller than the angle between the first guide arm 6214 and the second side panel 617, so that the resistance when the detachable fan module 500 is pushed out is slightly smaller, which is conducive to pushing out the detachable fan module 500.

[0081] One end of the second inclined arm 6215 connected to the first guide arm 6214 is spaced apart from the first side wall of the receiving cavity 611. One end of the second inclined arm 6215 away from the first guide arm 6214 is connected (fixed) to the first side wall of the receiving cavity 611.

[0082] Further optionally, the distance between one end of the second inclined arm 6215 connected to the first guide arm 6214 and the first side wall (second side panel 617) of the accommodating cavity 611 is close to or equal to the distance between one end of the first inclined arm 6211 connected to the first abutment arm 6212 and the first side wall (second side panel 617) of the accommodating cavity 611.

[0083] The distance between one end of the second inclined arm 6215 connected to the first guide arm 6214 and the first side wall (second side panel 617) of the accommodating cavity 611 is greater than the distance in the Y direction between the second abutment arm 6213 and one end of the second inclined arm 6215 connected to the first guide arm 6214, so that the first elastic member has sufficient elastic deformation space.

[0084] When the detachable fan module 500 is inserted into the installation frame 610, the detachable fan module 500 squeezes the first guide arm 6214, and the first inclined arm 6211 and the second inclined arm 6215 are deformed, so that the first guide arm 6214, the second abutment arm 6213 and the first abutment arm 6212 all move toward the second side panel 617. When the detachable fan module 500 is in place, the first guide arm 6214, the second abutment arm 6213 and the first abutment arm 6212 are stuck in the first limiting groove. Furthermore, the first abutment arm 6212 fits with the first groove wall 5031 to lock the detachable fan module 500 in the installation frame 610, prevent the detachable fan module 500 from moving out of the accommodating cavity 611 and keep the detachable fan module 500 in the installed position.

[0085] Optionally, the second fixing member 622 and the first fixing member 621 may have the same structure. The first fixing member 621 and the second fixing member 622 are symmetrically arranged on two sides of the detachable fan module 500 .

[0086] Further optionally, the structure of the second fixing member 622 may refer to the structure of the first fixing member 621 .

[0087] For details, please refer to Figure 8 and Fig. 9 The second elastic member (such as the aforementioned second elastic arm) includes a third inclined arm 6221, a third abutting arm 6222, a fourth abutting arm 6223, a second guide arm 6224 and a fourth inclined arm 6225 which are bent and connected in sequence.

[0088] One end of the third inclined arm 6221 away from the third abutting arm 6222 is fixedly connected to the second side wall of the receiving cavity 611 (close to the third side panel 618). The end of the third inclined arm 6221 connected to the third abutting arm 6222 is spaced from the second side wall of the receiving cavity 611. In other words, one end of the third inclined arm 6221 is fixedly connected to the position of the fourth side panel 619 close to the third side panel 618. The other end of the third inclined arm 6221 extends in a direction gradually away from the fourth side panel 619 and away from the third side panel 618, and the extension direction of the third inclined arm 6221 is inclined to both the X direction and the Y direction. Further, the angle between the third inclined arm 6221 and the fourth side panel 619 is smaller than the angle between the third inclined arm 6221 and the third side panel 618. Further optionally, the angle between the third inclined arm 6221 and the fourth side panel 619 is about 15° to 40°. If the angle between the third inclined arm 6221 and the fourth side panel 619 is too small, the elastic deformation size of the second elastic member in the Y direction will be small; if the angle between the third inclined arm 6221 and the fourth side panel 619 is too large, the second elastic member will occupy a larger space in the Y direction, and the size of the installation frame 610 in the Y direction will be larger, thus resulting in the installation frame 610 occupying a larger space.

[0089] The third abutting arm 6222 and the fourth abutting arm 6223 are used to engage with the groove wall of the first limiting groove when the detachable fan module 500 is in the installed state.

[0090] Specifically, the third abutting arm 6222 is bent compared to the third inclined arm 6221. The angle between the third abutting arm 6222 and the fourth side panel 619 is greater than the angle between the third inclined arm 6221 and the fourth side panel 619, and the angle between the third abutting arm 6222 and the fourth side panel 619 is less than 90°.

[0091] Optional, see Figure 8 and Fig. 9 The groove wall of the second limiting groove includes a fourth groove wall 5041, a fifth groove wall 5042, and a sixth groove wall 5043 along the X direction. The fourth groove wall 5041 is inclined compared to the X direction, and the third abutting arm 6222 is used to be arranged in the second limiting groove and abut the fourth groove wall 5041 to limit the detachable fan module 500 in the X direction.

[0092] The fourth abutting arm 6223 is bent compared to the third abutting arm 6222. The angle between the fourth abutting arm 6223 and the fourth side panel 619 is smaller than the angle between the third abutting arm 6222 and the fourth side panel 619. Further optionally, the angle between the fifth slot wall 5042 and the fourth side panel 619 is 0° or close to 0°, the fourth abutting arm 6223 is used to be arranged in the second limiting slot and abut the fifth slot wall 5042, and the angle between the fourth abutting arm 6223 and the fourth side panel 619 is 0° or close to 0°, so that the force of the fourth abutting arm 6223 on the fan housing 502 is substantially along the Y direction, so as to limit the detachable fan module 500 in the Y direction.

[0093] The second guide arm 6224 is used to guide the detachable fan module 500 when it is inserted into the receiving cavity 611 .

[0094] Specifically, the second guide arm 6224 is bent compared to the fourth abutting arm 6223. The second guide arm 6224 extends from one end of the fourth abutting arm 6223 toward a direction close to the fourth side panel 619 and gradually away from the third side panel 618.

[0095] The angle between the second guide arm 6224 and the fourth side panel 619 is greater than the angle between the third inclined arm 6221 and the fourth side panel 619, and the angle between the third abutment arm 6222 and the fourth side panel 619 is smaller than the angle between the third abutment arm 6222 and the fourth side panel 619. During the insertion of the detachable fan module 500 into the accommodating cavity 611, the second elastic member has sufficient deformation space and the inclination angle of the second guide arm 6224 is not too steep, thereby gradually guiding the detachable fan module 500 into the accommodating cavity 611.

[0096] Optionally, the sixth slot wall 5043 is inclined relative to the X direction, and the angle between the sixth slot wall 5043 and the fourth side panel 619 is smaller than the angle between the second guide arm 6224 and the fourth side panel 619. When the detachable fan module 500 is in the installed state, the sixth slot wall 5043 and the second guide arm 6224 are spaced apart. In the process of the detachable fan module 500 being pushed out, the sixth slot wall 5043 can serve as a guide slot wall for the detachable fan module 500 to be moved out. The angle between the sixth slot wall 5043 and the fourth side panel 619 is smaller than the angle between the second guide arm 6224 and the fourth side panel 619, so that the resistance when the detachable fan module 500 is pushed out is slightly smaller, which is conducive to pushing out the detachable fan module 500.

[0097] One end of the fourth inclined arm 6225 connected to the second guide arm 6224 is spaced apart from the second side wall of the receiving cavity 611. One end of the fourth inclined arm 6225 away from the second guide arm 6224 is connected (fixed) to the second side wall of the receiving cavity 611.

[0098] Further optionally, the distance between one end of the fourth inclined arm 6225 connected to the second guide arm 6224 and the second side wall (fourth side panel 619) of the accommodating cavity 611 is close to or equal to the distance between one end of the third inclined arm 6221 connected to the third abutting arm 6222 and the second side wall (fourth side panel 619) of the accommodating cavity 611.

[0099] The distance between one end of the fourth inclined arm 6225 connected to the second guide arm 6224 and the second side wall (fourth side panel 619) of the accommodating cavity 611 is greater than the distance in the Y direction between the fourth abutment arm 6223 and one end of the fourth inclined arm 6225 connected to the second guide arm 6224, so that the second elastic member has sufficient elastic deformation space.

[0100] When the detachable fan module 500 is inserted into the installation frame 610, the detachable fan module 500 squeezes the second guide arm 6224, and the third inclined arm 6221 and the fourth inclined arm 6225 are deformed, so that the second guide arm 6224, the fourth abutment arm 6223 and the third abutment arm 6222 all move toward the fourth side panel 619. When the detachable fan module 500 is in place, the second guide arm 6224, the fourth abutment arm 6223 and the third abutment arm 6222 are inserted into the second limiting groove. Furthermore, the third abutment arm 6222 fits with the fourth groove wall 5041 to lock the detachable fan module 500 in the installation frame 610, prevent the detachable fan module 500 from moving out of the accommodating cavity 611 and keep the detachable fan module 500 in the installed position.

[0101] For the first optional implementation, please refer to Figure 5 The first limiting portion 503 is a wedge-shaped groove, and the second limiting portion 504 is a wedge-shaped groove.

[0102] Optionally, the groove wall of the first limiting groove (first limiting portion 503) includes a first groove wall 5031, a second groove wall 5032, and a third groove wall 5033 along the X direction. The first groove wall 5031 is inclined relative to the X direction. The angle between the second groove wall 5032 and the second side panel 617 is 0° or close to 0°. The third groove wall 5033 is inclined relative to the X direction, and the angle between the third groove wall 5033 and the second side panel 617 is smaller than the angle between the first guide arm 6214 and the second side panel 617.

[0103] Optionally, the groove wall of the second limiting groove (the second limiting portion 504) includes a fourth groove wall 5041, a fifth groove wall 5042, and a sixth groove wall 5043 along the X direction. The fourth groove wall 5041 is inclined relative to the X direction. The angle between the fifth groove wall 5042 and the fourth side panel 619 is 0° or close to 0°. The sixth groove wall 5043 is inclined relative to the X direction, and the angle between the sixth groove wall 5043 and the fourth side panel 619 is smaller than the angle between the second guide arm 6224 and the fourth side panel 619.

[0104] For the second optional implementation, please refer to Fig.10 The first limiting portion 503 is a wedge-shaped groove, and the second limiting portion 504 is an arc-shaped groove.

[0105] Optionally, the groove wall of the first limiting groove (first limiting portion 503) includes a first groove wall 5031, a second groove wall 5032, and a third groove wall 5033 along the X direction. The first groove wall 5031 is inclined relative to the X direction. The angle between the second groove wall 5032 and the second side panel 617 is 0° or close to 0°. The third groove wall 5033 is inclined relative to the X direction, and the angle between the third groove wall 5033 and the second side panel 617 is smaller than the angle between the first guide arm 6214 and the second side panel 617.

[0106] Optionally, the second limiting groove (second limiting portion 504) is an arc-shaped groove, and correspondingly, the middle portion of the second elastic member is arc-shaped, and the arc-shaped second elastic member is arranged in the arc-shaped second limiting groove.

[0107] Since the pushing mechanism 630 is located on the side where the first side wall of the receiving chamber 611 is located, the force of the pushing mechanism 630 on the bottom of the detachable fan module 500 is more biased towards the first side wall of the receiving chamber 611. In this way, the force of the pushing mechanism 630 on the bottom of the detachable fan module 500 close to the second side wall of the receiving chamber 611 is weaker than the force of the pushing mechanism 630 on the bottom of the detachable fan module 500 close to the first side wall of the receiving chamber 611. In this way, by designing the second limiting groove (second limiting portion 504) as an arc groove, the middle portion of the second elastic member is in an arc shape, so that the force of the second elastic member disengaging from the second limiting groove is smaller than the force of the first elastic member disengaging from the first limiting groove. In this way, even if the force of the second side wall of the bottom of the detachable fan module 500 close to the receiving cavity 611 is weaker than the force of the first side wall of the bottom of the detachable fan module 500 close to the receiving cavity 611, the detachable fan module 500 can be stably pushed out along the X direction to avoid the problem of the detachable fan module 500 deviating from the center line due to the relatively large force of the pushing mechanism 630 on the first side wall close to the receiving cavity 611, and then getting stuck during disassembly and pushing out.

[0108] Optional, see Fig.11 , based on the aforementioned first limiting portion 503 being a wedge-shaped groove, and the second limiting portion 504 being a wedge-shaped groove or an arc-shaped groove. The groove depth of the second limiting portion 504 is less than the groove depth of the first limiting portion 503. In this way, the force of the second elastic member disengaging from the second limiting groove is less than the force of the first elastic member disengaging from the first limiting groove. In this way, even if the force of the pushing mechanism 630 applied to the second side wall of the bottom of the detachable fan module 500 close to the receiving cavity 611 is weaker than the force of the pushing mechanism 630 applied to the first side wall of the bottom of the detachable fan module 500 close to the receiving cavity 611, the detachable fan module 500 can be pushed out stably along the X direction, so as to avoid the problem that the detachable fan module 500 deviates from the center line due to the relatively large force of the pushing mechanism 630 applied to the first side wall close to the receiving cavity 611, and then gets stuck during removal and pushing out.

[0109] Optionally, the engagement force between the first limiting portion 503 and the first elastic member is greater than the engagement force between the second limiting portion 504 and the second elastic member. In a specific embodiment, the first limiting portion 503 is a wedge-shaped groove, and the second limiting portion 504 is an arc-shaped groove. In another specific embodiment, the groove depth of the second limiting portion 504 is less than the groove depth of the first limiting portion 503. By making the engagement force between the second limiting portion 504 and the second elastic member smaller than the engagement force between the first limiting portion 503 and the first elastic member, the force of the second elastic member disengaging from the second limiting groove is smaller than the force of the first elastic member disengaging from the first limiting groove, so that the detachable fan module 500 can be smoothly pushed out along the X direction.

[0110] Optional, see Figure 5 The pushing mechanism 630 also includes a first elastic portion 633 .

[0111] The pushing portion 631 is a pushing rod (numbered 631 in the figure). The pushing rod is arranged along the X direction. The pushing rod is located between the second side panel 617 and the fan housing 502. The pushing rod and the first fixing member 621 are arranged in sequence in the Z direction. The rotating portion 632 is a rotating rod (numbered 632 in the figure). The rotating rod is located between the bottom of the detachable fan module 500 and the third side panel 618. The rotating rod is arranged along the Y direction. The first end of the rotating rod is close to the second side panel 617, and the second end of the rotating rod is located at the bottom of the detachable fan module 500.

[0112] See also Figure 5 The push rod is located at a side of the first end of the rotating rod away from the third side panel 618. The first elastic portion 633 is located between the first end of the rotating rod and the third side panel 618.

[0113] The first elastic part 633 includes but is not limited to being an elastic member. Further, the first elastic part 633 includes but is not limited to being a spring.

[0114] See also Figure 5 One end of the push rod and the first elastic part 633 are respectively in contact with the two sides of the first end of the rotating rod. On the one hand, the push rod can push the first end of the rotating rod to move toward one side of the third side panel 618 after being subjected to force, and the first elastic part 633 is compressed. On the other hand, when the force on the push rod is removed, the push rod can be restored to its original position under the deformation recovery force of the first elastic part 633.

[0115] See also Figure 5 , the axis of the rotating rod extends in the direction toward the side where the main board 600 is located. The axis of the rotating rod is arranged along the Z-axis direction. When the push rod is subjected to force and pushes the first end of the rotating rod to move toward the third side panel 618, the second end of the rotating rod pushes the detachable fan module 500 away from one side of the through hole 612, so that the first limiting portion 503 and the second limiting portion 504 of the detachable fan module 500 are separated from the first fixing member 621 and the second fixing member 622, thereby making the detachable fan module 500 no longer constrained by the first fixing member 621 and the second fixing member 622 and being pushed out.

[0116] See also Figure 5 One end of the push rod away from the first end of the rotating rod is located in the receiving cavity 611, so that the push rod moves toward the third side panel 618 under the action of the external push rod.

[0117] For further optional information, see Fig.12 The installation frame 610 is provided with a sliding groove 661 isolated from the receiving cavity 611, and the push rod is installed in the sliding groove 661. When the detachable fan module 500 is in the installation state, one end of the push rod abuts against one end groove wall of the sliding groove 661 along the X direction (the end close to the through hole 612), and one end of the first elastic portion 633 away from the first end of the rotating rod abuts against the other end groove wall of the sliding groove 661 along the X direction.

[0118] See also Fig.12 An operating hole 662 connected to the sliding groove 661 is also provided in the installation frame 610. One end of the operating hole 662 is connected to the groove wall of the sliding groove 661 close to the through hole 612, and the other end of the operating hole 662 passes through the fan cover 501. The size of the operating hole 662 is smaller than that of the sliding groove 661. The operating hole 662 is used to allow the push rod to penetrate and abut against the push rod.

[0119] See also Fig.12 The pushing mechanism 630 also includes a pushing plate 634 and a second elastic portion 635 .

[0120] See also Fig.12 The push plate 634 is disposed on a side of the detachable fan module 500 away from the through hole 612 (the bottom of the detachable fan module 500 ). The push plate 634 is opposite to the third side panel 618 .

[0121] See also Fig.12 The second end of the rotating rod abuts against the pushing plate 634, and the rotating rod rotates under the action of the pushing rod to drive the pushing plate 634 to move toward the through hole 612. Due to the setting of the pushing plate 634, the bottom force of the detachable fan module 500 is more balanced, which is conducive to the detachable fan module 500 being pushed out more stably.

[0122] The second elastic portion 635 elastically contacts between the pushing plate 634 and the bottom of the receiving groove (the third side panel 618 ).

[0123] The second elastic portion 635 includes but is not limited to a spring, so as to provide an auxiliary thrust to push the detachable fan module 500 out of the receiving chamber 611. When the detachable fan module 500 is inserted into the receiving chamber 611, the second elastic portion 635 is compressed.

[0124] Optionally, the pushing portion 631 , the rotating portion 632 , the second elastic portion 635 , and the pushing plate 634 exert force on the detachable fan module 500 , so that the detachable fan module 500 is pushed out of the receiving chamber 611 .

[0125] Optionally, when the detachable fan module 500 is in the installed state, the rotating rod is arranged along the Y direction. The second end of the rotating rod and the second elastic portion 635 are respectively arranged on both sides of the pushing plate 634 along the Y direction.

[0126] Optional, see Fig.12 , a first electrical interface portion 636 is provided on a side of the detachable fan module 500 away from the through hole 612. The first electrical interface portion 636 includes but is not limited to a type C interface, a USB interface, etc.; a second electrical interface portion 637 is provided on the mainboard 600. The second electrical interface portion 637 is adapted to the first electrical interface portion 636. The second electrical interface portion 637 is electrically connected to a power management chip, etc. When the detachable fan module 500 is in an installed state, the first electrical interface portion 636 is plugged into the second electrical interface portion 637, and the detachable fan module 500 is electrically connected to the battery 700. When the detachable fan module 500 is in a disassembled state, the second electrical interface portion 637 is separated from the first electrical interface portion 636, and the detachable fan module 500 is separated from the battery 700.

[0127] Optional, see Figure 4The fan cover 501 is provided with an air inlet 5011. The air inlet 5011, the inner cavity of the fan housing 502 and the air outlet of the detachable fan module 500 are connected in sequence. When the fan body 505 rotates, the fan body 505 draws external cold air into the inner cavity of the fan housing 502, and blows it to the first opening 616 of the installation frame 610 through the air outlet of the detachable fan module 500, and then blows the cold air to the heating element 640 of the mainboard 600 to take away the heat of the heating element 640 and dissipate the heat of the heating element 640.

[0128] Optionally, the air inlet 5011 of the detachable fan module 500 is located on the second surface plate 614 of the mounting frame 610. A vent is provided on the rear cover 400. When the fan body 505 rotates, the fan body 505 draws external cold air into the inner cavity of the fan housing 502 through the vent of the rear cover 400 and the air inlet 5011 on the second surface plate 614, and blows the cold air to the first opening 616 of the mounting frame 610 through the air outlet of the detachable fan module 500, and then blows the cold air to the heating element 640 of the mainboard 600 to take away the heat of the heating element 640 and dissipate the heat of the heating element 640.

[0129] As mentioned above, see Fig.12 The mobile terminal 1000 further includes a frame 320. The frame 320 has a first frame hole 325 and a second frame hole 326. The mounting frame 610 is disposed in the frame 320. The first frame hole 325 is connected to the through hole 612 or is the same hole. The heating element 640 on the mainboard 600 is disposed between the first frame hole 325 and the second frame hole 326.

[0130] See also Fig.12 , the first frame hole 325 is located at the first side frame 322, and the second frame hole 326 is located at the second side frame 323. When the fan body 505 rotates, the fan body 505 draws the external cold air into the inner cavity of the fan housing 502 through the first frame hole 325 on the first side frame 322, and blows it to the first opening 616 of the installation frame 610 through the air outlet of the detachable fan module 500, and then blows the cold air to the heating element 640 of the mainboard 600 to take away the heat of the heating element 640, and dissipate the heat of the heating element 640, and the hot air is blown away through the second frame hole 326. A fast-flowing air heat dissipation duct is formed between the first frame hole 325 and the second frame hole 326, and the heat dissipation duct passes through the heating element 640 on the mainboard 600, and can quickly dissipate the heat on the heating element 640.

[0131] In other embodiments, the second frame hole 326 may not be provided, and cold air is blown to the heating element 640 of the mainboard 600 to take away the heat of the heating element 640 and dissipate the heat of the heating element 640 . The hot air can be blown out through the installation gap or installation hole of the mobile terminal 1000 .

[0132] Optional, see Fig.13 The mobile terminal 1000 further includes a mainboard pressing plate 650. The mainboard pressing plate 650 is disposed between the rear cover 400 and the mainboard 600. The mainboard pressing plate 650 is fixed to the mainboard 600 to press the multiple chip modules on the mainboard 600, and is used to fix the multiple chip modules.

[0133] See also Fig.13 The mainboard pressing plate 650 includes a main body 651 and a protruding portion 652 protruding relative to the main body 651. The main body 651 and the protruding portion 652 are an integral structure.

[0134] The main body 651 is fixedly connected to the middle frame 300 of the mobile terminal 1000 to fix the main board 600 to the middle frame 300. Multiple corners of the main body 651 are fixedly connected to the main board 600 or the middle frame 300. The distance formed between the protrusion 652 and the main board 600 is greater than the distance formed between the main body 651 and the main board 600. In other words, the protrusion 652 is a portion of the main board pressing plate 650 that is closer to the back cover 400 than other positions. Further, the distance between the main body 651 and the components on the main board 600 is less than the distance between the protrusion 652 and the components on the main board 600. When cold air enters the main board pressing plate 650, the protrusion 652 and the components on the main board 600 can form a channel for the cold air to pass through.

[0135] In an alternative embodiment, see Fig.13 A portion of the protrusion 652 forms the installation frame 610, and another portion of the protrusion 652 forms an air duct from the installation frame 610 to the second frame hole 326. In other words, the installation frame 610 and the protrusion 652 of the mainboard pressure plate 650 are an integrated structure.

[0136] For further optional information, see Fig.13 The protrusion 652 includes a first protrusion 6521. The first protrusion 6521 is substantially rectangular. The first protrusion 6521 may be a rectangular frame protruding from the main body 651 toward the rear cover 400.

[0137] The first protrusion 6521 is connected to the first side frame 322, and the first protrusion 6521 forms the installation frame 610. The through hole 612 of the installation frame 610 is connected to the first frame hole 325. The second side panel 617 is connected between the second surface plate 614 and the main body 651. The third side panel 618 is connected between the second surface plate 614 and the main body 651. The fourth side panel 619 is connected between the second surface plate 614 and the main body 651.

[0138] In this embodiment, the mainboard pressure plate 650 is designed to form a first protrusion 6521 on the mainboard pressure plate 650 that protrudes toward the side of the rear cover 400. The first protrusion 6521 has a through hole 612 facing the first side frame 322, and the through hole 612 is connected to the first frame hole 325 on the first side frame 322. The side of the first protrusion 6521 facing the mainboard 600 is a first opening 616. In this way, the first protrusion 6521 forms an installation frame 610. In this way, the detachable fan module 500 can be installed in the installation frame 610 through the first frame hole 325 and the through hole 612, and fixed by the fixing mechanism 620 in the installation frame 610, so that the detachable fan module 500 is in an installed state.

[0139] For further optional information, see Fig.13 The protrusion 652 further includes a second protrusion 6522, which is disposed on the heating element 640. When the number of the heating element 640 is plural, the number of the second protrusion 6522 is also plural. Each second protrusion 6522 corresponds to one heating element 640.

[0140] For further optional information, see Fig.13 The protrusion 652 further includes a plurality of connecting protrusions 6523, and the connecting protrusions 6523 are connected between the first protrusion 6521 and the second protrusion 6522. The connecting protrusions 6523 form a connecting air passage. Further, the width of the connecting protrusion 6523 is smaller than the width of the first protrusion 6521, and also smaller than the width of the second protrusion 6522. In this way, the detachable fan module 500 allows the external cold air to enter the relatively wide second protrusion 6522 after passing through the narrow connecting air passage at the first protrusion 6521, so that the wind speed of the second protrusion 6522 is relatively large, which is conducive to taking away the heat of the heating element 640 corresponding to the second protrusion 6522, thereby improving the heat dissipation efficiency.

[0141] The second protrusion 6522 closest to the second side frame 323 has a ventilation hole, which is connected to the second frame hole 326 on the second side frame 323 to blow the hot air in the second protrusion 6522 out of the second frame hole 326 to form a continuous cold air duct, thereby quickly dissipating the heat of the heating element 640 on the mainboard 600.

[0142] Optional, see Fig.14 At least one heating element 640 is disposed on the main board 600. At least a portion of the top wall of the protrusion 652 facing the heating element 640 is an inclined surface 653. The distance between the side of the inclined surface 653 close to the first frame hole 325 and the main board 600 is greater than the distance between the side of the inclined surface 653 close to the second frame hole 326 and the main board 600.

[0143] Specifically, the top plate of the protrusion 652 is an inclined plate, and specifically, the inclined plate is gradually inclined from the side close to the first frame hole 325 toward the side close to the second frame hole 326, and the distance between the side of the inclined plate close to the first frame hole 325 and the main board 600 is greater than the distance between the side of the inclined plate close to the second frame hole 326 and the main board 600. The portion of the main board pressing plate 650 facing the heating element 640 is an inclined surface 653, so as to guide the wind to the heating element 640, so as to ensure that the cold wind blows toward the heating element 640, dissipates the heat from the heating element 640, and improves the heat dissipation efficiency.

[0144] Optional, see Fig.15 , the installation frame 610 is provided with an arc-shaped air guide plate 654 on one side facing the second frame hole 326. The arc-shaped air guide plate 654 is connected to the first side panel 615 and extends toward the side where the main board 600 is located. When the fan body is running, the arc-shaped air guide plate 654 reflects the airflow to the side where the heating element 640 on the main board 600 is located, reducing the cold air flowing to other directions where heat dissipation is not required, so that the cold air flows more concentratedly to the heating element 640 on the main board 600.

[0145] The detachable fan module 500 provided in the present application is a cooling fan. The cooling fan is mainly used to dissipate heat from the heat source at the position of the mobile phone mainboard 600. Optionally, the present application installs the detachable fan module 500 from the side frame 320 of the mobile phone. Through the detachable design, the detachable fan module 500 can be removed for cleaning and replacement without disassembling the entire device. The detachable fan module 500 can be powered on and operated by inserting it back into the installation frame 610.

[0146] When the removable fan module 500 is inserted back into the installation frame 610, the removable fan module 500 is fixed by the fixing members on both sides of the accommodating cavity 611 of the installation frame 610 and the fixing grooves (the first limiting groove and the second limiting groove) of the fan housing 502; the fixing members can be metal sheets with a certain elasticity; and the fan housing 502 is a rigid material, which can be a metal or non-metal material.

[0147] When installing the detachable fan module 500, the detachable fan module 500 is inserted into the installation frame 610 by pressing the fan cover 501, so that the fixing parts of the accommodating cavity 611 are locked with the fan housing 502. At the same time, the electrical connector plug (first electrical interface part 636) of the detachable fan module 500 is tightly plugged into the fan socket (second electrical interface part 637) located on the mainboard 600 to connect the power supply path.

[0148] When the detachable fan module 500 needs to be taken out of the mobile phone for cleaning or replacement, the push rod in the installation frame 610 is pushed by the ejector pin (thrust rod), and then the rotating rod is rotated through the rotating shaft so that the thrust acts on the push plate 634. At this time, under the action of the rotating rod and the spring on the other side (the second elastic part 635), the push plate 634 separates the fixing part from the fan housing 502, thereby sending the detachable fan module 500 out of the installation frame 610.

[0149] The detachable fan module 500 is designed with an electrical connector plug (first electrical interface part 636) in the installation frame 610, and a passage is formed between the plug and the motor of the detachable fan module 500. When the detachable fan module 500 is in a locked state inside the receiving cavity 611 of the mobile phone, the electrical connector plug (first electrical interface part 636) of the fan is inserted into the fan socket (second electrical interface part 637) on the mainboard 600 to form an electrical passage, and the socket (second electrical interface part 637) is powered by the mainboard 600 of the mobile phone, and the mainboard 600 and the fan socket (second electrical interface part 637) are connected through a power supply connector and an FPC soft board. The electrical connector plug (first electrical interface part 636) and the fan socket (second electrical interface part 637) adopt a standard USB and type C interface design, which is more versatile and more stable.

[0150] The detachable fan module 500 provided in the present application is detachable. The detachable fan module 500 can be cleaned and repaired without disassembling the entire device, thereby reducing after-sales repair costs and the risk of damage to the mobile phone. The electrical connection plug and socket of the detachable fan module 500 adopt a standard type C design, which improves the efficiency of the fan power supply design. The built-in detachable fan module 500 provided in the present application can be taken out from the inside of the mobile phone without disassembling the entire device. The power supply of the detachable fan module 500 adopts a standard parts design, which improves the design efficiency and fan versatility.

[0151] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
