[Prior Art] [0002] At present, the integration degree of notebook computers is getting higher and higher, the volume is getting smaller and smaller, and the heat dissipation problem is also becoming more and more prominent. In order to improve the cooling efficiency of notebook computers, many laptops are additionally equipped with a cooling pad at the bottom. However, although the thermal pad can achieve the required heat dissipation performance, it needs to be carried as an accessory, which often causes great inconvenience to the user. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide an electronic device with an auxiliary heat dissipation structure [0004] an electronic device including a host having a working circuit, the bottom of the host is provided with a heat dissipation hole and a perforation The electronic device is further provided with a support member disposed through the through hole for supporting the host on other objects, a driving device for driving the driving support in the axial direction of the through hole, a temperature detecting unit for detecting the internal temperature of the host, and The temperature measured by the temperature detecting unit controls the control unit that drives the movement of the support. [0005] The support member at the bottom of the electronic device is stretched as the temperature of the host changes, to adjust the interval between the host and the object carrying the host, to provide a suitable flow space for the heat dissipation airflow, thereby achieving the effect of assisting heat dissipation. [Embodiment] [0006] Please refer to FIG. 1, which is a perspective view of an electronic device 10 having an auxiliary heat dissipation structure according to an embodiment of the present invention. The electronic device 10 can be a portable computer, handheld 098102390 Form No. A0101 Page 4 of 16 1003427544-0 1375882 On November 18, 100, the shuttle is replacing the terminal and other products. The electronic device 10 includes a host 100 and a display 200 rotatably coupled to the host 100. Referring to FIG. 2 at the same time, the host 100 has a square shape, and the bottom portion 101 is provided with a heat dissipation hole 102; the bottom portion 101 is provided with a foot pad 104 at two corners away from the display screen 200; and the bottom portion 101 is adjacent to the two corners of the display screen 200. Circular perforations 106 are respectively opened. Referring to FIG. 3 and FIG. 4 together, the inner surface of the bottom portion 101 of the main body 100 further has a guiding portion 110 disposed around the through hole 106, a cylindrical supporting member 108 disposed through the through hole 106, and a driving support member 108 at the through hole 106. The drive device 300 is moved in the axial direction. The guide portion 110 is composed of three curved baffles surrounding the perforations 106 for guiding the support member 108 to move in the axial direction of the perforations 106. The portion of the support member 108 located inside the main body 100 is provided with a rack 18 2 arranged in the moving direction. The drive device 300 includes a motor 302 and a transmission mechanism 304. The transmission mechanism 304 meshes with the rack 182 for driving the support member 108 to move under the driving of the motor 302. The transmission mechanism 304 is a gearbox formed by a plurality of gears cooperating with each other. The shifting principle of the transmission allows the motor 302 to easily drive the support member 108 to lift the electronic device 10, and the accuracy of the lifting size can be improved. Please refer to FIG. 5, which is a functional block diagram of the electronic device 10. The electronic device 10 includes a working circuit 402, a temperature detecting unit 404, a control unit 406, and the above-described driving device 300. The working circuit 402 is used to implement the main functions of the electronic device 10; the temperature detecting unit 404 is for detecting the internal temperature of the electronic device 10, including the temperature of some of the components on the working circuit 402. The control unit 406 is configured to control the driving of the support 108 by the driving device 300 according to the temperature measured by the temperature detecting unit 404, including when the temperature reaches a predetermined height, 098102390 Form No. A0101 Page 5 / Total 16 Page 1003427544-0 T375882 10 0 11 j 18 The control support member 108 is moved in the direction of the projecting perforations 1〇6, and when the temperature is low to a predetermined level, the support member 108 is moved in the direction of retracting into the perforation 106. Referring to FIG. 6, in the initial state, the height of the support member 〇8 extending through the through hole 1〇6 is equivalent to the height of the foot pad 104, so that the electronic device 1〇 can be smoothly placed on the table top 500. The bottom portion 1〇1 of the main unit 100 is spaced apart from the table top 5〇〇 to facilitate the flow of the heat-dissipating airflow blown from the heat dissipation holes 1〇2 on the bottom portion 101. Referring to FIG. 7 at the same time, when the internal temperature of the main unit 1 is too high, the support member 108 moves in the direction of extending the perforation 1〇6 based on the driving device 300, so that the bottom of the main unit 100 is 1〇1 and the desktop. The distance between the five turns increases, and the space between the two becomes larger, providing more space for the flow of the heat-dissipating gas, thereby achieving the effect of improving the heat dissipation efficiency, thereby eliminating the inconvenience of the user additionally providing the heat-dissipating pad. The problem. [0011] When the electronic device 10 receives the shutdown command, the system first issues a chemical number to control the support member 〇8 to retract to the initial state, and then performs the shutdown operation of the electronic device 10.
