Detailed Description

Referring to fig. 1A, fig. 1A is a schematic view of a notebook computer 10 in a normal mode according to an embodiment of the invention. The notebook computer 10 includes a keyboard base 102 and a screen device (not shown). The keyboard base 102 has a motherboard (not shown), and a plurality of processors (such as a Central Processing Unit (CPU) and a Graphics Processing Unit (GPU)), a heat dissipation motor circuit, and a turbo key switch (turbo key) are disposed on the motherboard. The keyboard base 102 is provided with a plurality of air inlets 104 capable of being opened and closed, and an over-frequency key 106 corresponding to an over-frequency switch on the main board. As shown in fig. 1A, when the processor of the notebook computer 10 is in the normal mode, the air inlet 104 is closed, and heat dissipation is performed only through the air holes 104a and the fan 100a of the heat dissipation motor circuit. Referring to fig. 1B, fig. 1B is a schematic diagram of a notebook computer in an over-clocking mode according to an embodiment of the invention. As shown in fig. 1B, when the user presses the over-frequency button 106, the processor of the notebook computer 10 enters the over-frequency mode from the normal mode, and the over-frequency switch is turned on and generates a trigger signal to the heat dissipation motor circuit, so as to open the air inlet 104, thereby increasing the air suction volume of the air inlet. In other words, the present invention not only can improve the utilization efficiency of the processor of the notebook computer 10 by one physical key, but also can increase the air suction volume of the air suction opening to further improve the heat dissipation efficiency, so that the user has better use experience in the over-frequency state.

It should be noted that the embodiment of the present invention is not limited to the over-frequency mode being started or closed by the over-frequency button 106, but the over-frequency mode may also be started by a user interface (such as software/firmware), so that the processor enters the over-frequency mode from the normal mode, and generates an instruction or a trigger signal to the heat dissipation motor circuit to drive the opening of the air suction opening 104, so as to increase the air suction volume of the air suction opening, thereby achieving the heat dissipation effect. In one embodiment, the user interface may be a physical key (i.e., the turbo key 106) corresponding to the turbo switch.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating an operation of opening and closing an air inlet according to an embodiment of the present invention. Specifically, when the user presses the turbo button 106, the trigger signal generated by the turbo switch is transmitted to the processor, so that the processor enters a turbo mode from a normal mode to increase the utilization rate of the processor, such as increasing the frequency and frequency of the CPU and GPU. Meanwhile, the trigger signal of the over-frequency switch is transmitted to the heat dissipation motor circuit, so that the motor 100b of the heat dissipation motor circuit drives the rack/scroll bar to open the air suction opening 104 (in the direction of the downward key head in the figure) through the gear, and thus the air intake amount of the air suction opening is increased. On the other hand, when the user presses the over-frequency button 106 again, the over-frequency switch generates a recovery signal, which is respectively transmitted to the processor and the heat dissipation motor circuit, so that the processor enters the normal mode from the over-frequency mode, and the motor 100b drives the rack/scroll bar through the gear to close the air inlet 104 (in the upward direction of the key head as shown in the figure).

Fig. 3 is an operation diagram of the heat dissipation motor circuit 100 according to an embodiment of the invention. The heat dissipation motor circuit 100 includes a motor 100B, P-type MOSFETs Q1-Q2 and N-type MOSFETs Q3-Q4, wherein the gates of the P-type MOSFETs Q1 and Q3 are connected to terminal A, and the gates of the P-type MOSFETs Q2 and Q3 are connected to terminal B. In one embodiment, the over-frequency switch SW on the motherboard is electrically connected to the micro-controller MCU for receiving the trigger signal and the recovery signal of the over-frequency switch SW, so as to respectively output the control signal DCMOTOR _ L, DCMOTOR _ R to the terminal A, B of the heat dissipation motor circuit 100 for controlling the motor 100b to rotate forward or backward. When the microcontroller MCU outputs the control signal DCMOTOR _ L to the terminal a, only the P-type mosfet Q2 and the N-type mosfet Q3 are turned on, so that the motor 100b rotates forward and the air inlet 104 is opened by the forward rotation gear. On the other hand, when the microcontroller MCU outputs the control signal DCMOTOR _ R to the terminal B, only the P-type mosfet Q1 and the N-type mosfet Q4 are turned on, so that the motor 100B rotates reversely, and the air inlet 104 is closed by rotating the gear reversely.

The present invention proposes to make a patterned air inlet opening above the keyboard base 102, when the user wants to switch to the overclocking mode, the user only needs to click the upper physical key (overclocking key 106), and after pressing down, the microcontroller MCU will output the control signal DCMOTOR _ L, DCMOTOR _ R, so as to make the motor rotate forward/backward, and further open/close the air inlet opening. Meanwhile, the microcontroller MCU will trigger the user interface program to increase the rotation speed of the fan 100a or the independent fans of the CPU and the GPU, so that the user can easily enjoy a system with better performance and user experience with better performance and heat dissipation. In addition, when the user presses the overdrive key 106 again, the micro-controller MCU can be used to adjust the rotation speed of the fan 100a or the independent fans of the processor CPU and GPU to a normal state through the user interface program.

In summary, the present invention provides a notebook computer capable of switching heat dissipation modes, which can adjust the air suction amount and the fan rotation speed according to different operation modes (such as a normal mode or an over-frequency mode) to improve the heat dissipation efficiency. For example, by completely opening the air suction opening on the keyboard base, timely heat dissipation in an over-frequency state can be achieved, so that damage to the processor or the mainboard is avoided, and the use efficiency of the competitive power notebook computer can be effectively improved.
