[0020] Attachment Figure 2 and attached Figure 3This schematic diagram illustrates the heat dissipation principle of a laptop computer according to a first embodiment of the present invention. The laptop computer in this embodiment comprises a display screen 1 and a main unit 2. The display screen 1 is rotatably connected to the main unit 2 via a main body hinge 3. The main unit 2 is provided with an air inlet 4 and an air outlet 5. The air inlet 4 is located at the bottom of the main unit 2, and the air outlet 5 is located at the rear of the main unit 2. The main unit 2 is also provided with a movable windshield 6, which is rotatably mounted on the main unit 2.

[0021] The windshield baffle 6 is connected to the main body shaft 3 through the transmission component 7. When the computer is turned on and used, the display screen 1 is opened from the main body part 2, and the transmission component 7 drives the windshield baffle 6 to rotate. When the LCD is opened to the maximum angle, the windshield baffle 6 rotates 180 degrees, and the air outlet 5 is fully opened. The windshield baffle 6 is flipped and supported at the bottom of the main body part 2. The windshield baffle 6 blocks the air inlet 4 and the air outlet 5 to prevent the backflow of hot air, thereby maximizing the heat dissipation capacity of the computer. When the laptop is closed, the transmission component 7 drives the windshield baffle 6 to rotate, and the display screen 1 is closed from the main body part 2. The windshield baffle 6 flips to the rear of the main body part 2 and closes the air outlet 5, shielding the internal structure, making the appearance beautiful, and at the same time sealing against dust and foreign matter. The present invention realizes the control of the air outlet by the opening and closing of the laptop display screen by linking the display screen with the windshield baffle, thereby ensuring the compatibility of the integrity of the laptop appearance and the heat dissipation performance.

[0022] Attachment Figure 4 To the attached Figure 15 The second embodiment of the present invention is described. The laptop computer in this embodiment includes a display screen 1 and a main body part 2. The display screen 1 is rotatably connected to the main body part 2 via a main body shaft 3. The main body part 2 is provided with an air inlet 4 and an air outlet 5. The air inlet 4 is located at the bottom of the main body part 2, and the air outlet 5 is located at the rear side of the main body part 2. The main body part 2 is provided with a movable windshield baffle 6, which is rotatably accommodated in the air outlet 5. When the display screen 1 is opened from the main body part 2, the windshield baffle 6 flips from the air outlet 5 to be supported at the bottom of the main body part 2 and blocks the air inlet 4 and the air outlet 5. For the sake of aesthetics and to prevent foreign matter from entering, a grille 8 is fixedly provided in the air outlet 5. The windshield baffle 6 is rotatably accommodated in the air outlet 5 around the grille 8.

[0023] The windshield baffle 6 is connected to the main shaft 3 via a transmission component 7. The main shaft 3 is provided with a first gear 31, and the windshield baffle 6 is provided with a fourth gear 61.

The first gear 31 meshes with the second gear 72, and the third gear 73 meshes with the fourth gear 61. Opening and closing the display screen 1 rotates the main shaft 3. The torque generated by the rotation of the main shaft 3 is transmitted through the transmission component 7, driving the windshield baffle 6 to flip. Through a two-stage gear transmission, the main shaft 3 and the windshield baffle 6 can rotate in the same direction. The base diameter ratio of the first gear 31 and the second gear 72 is 1:1, and the base diameter ratio of the third gear 73 and the fourth gear 61 is 2:1. The first gear 31 and the third gear 73 have quarter-circle teeth, while the second gear 72 and the fourth gear 61 have full-circle teeth. This arrangement enables torque transmission control.

[0024] Attachment Figure 4 To the attached Figure 6 The second embodiment of the present invention is a schematic diagram showing a laptop computer in a closed state. When the laptop computer is closed, the windshield baffle 6 can be rotated around the grille 8 and accommodated in the air outlet 5 .

[0025] Attachment Figure 7 To the attached Figure 9 A schematic diagram of a laptop computer in an open state in a second embodiment of the present invention is described. When the computer is turned on for use, the display screen 1 is opened from the main body part 2, and the main body shaft 3 rotates to transmit torque to the transmission component 7, so that the transmission component 7 drives the windshield partition 6 to rotate out of the air outlet 5.

[0026] Attachment Figure 10 To the attached Figure 12 The following is a schematic diagram of a laptop computer in a second embodiment of the present invention when it is opened at 90°. When the display screen 1 is opened to 90°, the windshield 6 flips 180°, and the air outlet is opened to the maximum without obstruction. The windshield 6 is against the desktop, blocking the air inlet 4 and the air outlet 5 to prevent hot air from flowing back, thereby maximizing the computer's heat dissipation capacity.

[0027] Attachment Figure 13 To the attached Figure 15 The following diagram illustrates a laptop computer in a second embodiment of the present invention, shown in a 120° opening position. When the display screen 1 is further opened beyond 90°, the first gear 31 and the second gear 72 disengage, torque cannot be transmitted, and the windshield 6 no longer rotates. The air outlet remains fully open, maintaining maximum heat dissipation efficiency. After use, when the display screen 1 is closed to 90°, the first gear 31 and the second gear 72 reengage, torque is transmitted normally to the main body shaft 3, and the windshield 6 retracts and rotates until the display screen 1 is fully closed, with the windshield 6 also completely retracted.
