Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Refer to Figures 1-4, A quickly detachable LED bottom case with good heat dissipation, including a back case 1 fixed to the back of the bottom case frame 14. A support plate 15 is rotatably connected to the side of the back case 1 away from the bottom case frame 14 for supporting the protective net 17. A second opening is provided in the support plate 15, and a protective net 17 is fixedly embedded in the second opening to prevent sundries from entering the first opening and damaging the fan blade 5. Magnets 18 that attract each other are fixedly connected to the opposite sides of the support plate 15 and the back case 1 to prevent the support plate 15 from loosening. A pull ring 19 is fixedly connected to the side of the support plate 15 away from the back case 1 to facilitate the user to lift the support plate 15. A square-shaped second rubber ring 16 is fixedly connected to the side of the support plate 15 close to the back case 1 to improve the sealing performance between the support plate 15 and the back case 1;

[0025] In this embodiment, a circular first opening is provided in the back case 1 and near the center position. A first rubber ring 12 is fixedly connected to the inner side wall of the first opening to prevent abrasion between the installation cylinder 2 and the inner side wall of the first opening. The inner diameter of the first opening is at least four-fifths of the width of the back case 1 to accommodate a larger-sized fan blade 5. An installation cylinder 2 is slidably inserted into the inner side wall of the first opening for installing the servo motor 3. A plurality of annularly distributed positioning grooves are provided on the outer side wall of the installation cylinder 2. A positioning block 13 is slidably inserted into the inner side wall of the positioning groove to cooperate with the positioning groove to position the installation cylinder 2, prevent it from rotating and misaligning. One end of the positioning block 13 penetrates the positioning groove and is fixedly connected to the inner side wall of the first opening;

[0026] In this embodiment, a servo motor 3 is provided in the installation cylinder 2 and near the center position for driving the fan blade 5 to rotate. The end of the output shaft of the servo motor 3 is fixedly connected to a fan blade 5 for driving air flow. The distance between the fan blade 5 and the inner side wall of the installation cylinder 2 is 0.5 - 2 CM to prevent the fan blade 5 from colliding and wearing with the inner side wall of the installation cylinder 2 when rotating. A support cylinder 4 is fixedly sleeved on the servo motor 3 for supporting the servo motor 3. A plurality of annularly distributed fixing rods 11 are fixedly connected to the outer side wall of the support cylinder 4 for supporting the support cylinder 4. The end of the fixing rod 11 away from the support cylinder 4 is fixedly connected to the inner side wall of the installation cylinder 2;

[0027] In this embodiment, chutes are provided on both the left and right sides of the back shell 1. A slider 10 is slidably connected to the inner side wall of the chute for driving the movement of the clamping block 7. Two guide rods 6 are slidably inserted into one side of the slider 10 away from the mounting cylinder 2 for guiding the movement of the slider 10. One end of the guide rod 6 penetrates through the slider 10 and is fixedly connected to the inner side wall of the chute. A lead screw 8 is inserted into one side of the slider 10 away from the mounting cylinder 2 for driving the movement of the slider 10. One end of the lead screw 8 penetrates through the chute, and the other end of the lead screw 8 penetrates through the slider 10 and is rotatably connected to the inner side wall of the chute. The lead screw 8 is threadedly connected to the slider 10. One end of the lead screw 8 penetrating through the chute is fixedly connected to a knob 9 for facilitating the user to rotate the lead screw 8. A clamping block 7 is fixedly connected to one side of the slider 10 close to the mounting cylinder 2 for cooperating with the clamping groove to prevent the mounting cylinder 2 from loosening. Clamping grooves corresponding to the clamping block 7 are provided on both sides of the mounting cylinder 2. One end of the clamping block 7 away from the slider 10 slidably penetrates through the back shell 1 and extends slidably into the clamping groove.

[0028] In this embodiment, first, the power supply of the servo motor 3 is turned on, and the servo motor 3 is started to drive the fan blade 5 to rotate. The air is driven to flow through the fan blade 5, thereby performing the heat dissipation operation. The knob 9 is manually rotated to drive the lead screw 8 to rotate. The lead screw 8 drives the slider 10 to move in the direction close to or away from the mounting cylinder 2 (controlled by the forward and reverse rotation of the lead screw 8). When the slider 10 moves in the direction away from the mounting cylinder 2, the clamping block 7 will be driven to disengage from the clamping groove. Then, the support plate 15 is manually lifted and rotated, and the mounting cylinder 2 together with the servo motor 3 and the fan blade 5 can be taken out and removed from the first opening for easy maintenance, cleaning, and repair operations. When the slider 10 moves in the direction close to the mounting cylinder 2, the clamping block 7 will be driven to move into the clamping groove, thereby locking the position of the mounting cylinder 2, and the complete installation operation can be completed.
