A certain type of notebook computer includes a base, a rotating shaft, a display and a telescoping mechanism for foot pads. One side of the base is pivotally connected with the display through the rotating shaft. When using the notebook computer, after the user turns on the display, the rotating shaft will be rotated in conjunction with the rotating shaft, and after the rotating shaft rotates, the foot pad telescopic mechanism will be driven to extend downwards to prop up the base. In this way, the effect of assisting the notebook computer in heat dissipation is achieved. However, since the foot pad telescopic mechanism lifts the base by extending vertically, when the user is operating the notebook computer, if the foot pad telescopic mechanism bears too much weight, the foot pad telescopic mechanism will It is easy to shrink into the inside of the base, and then cannot continue to support the base stably.

For this reason, some manufacturers have prepared a hinge device that can raise the base, and the hinge device that can raise the base can be assembled on the aforementioned electronic devices such as notebook computers. The hinge device of the elevating base includes a display screen support, a pivot frame, a spindle, a first gear, a second gear, a pivot and a tripod, and the display screen support is used to fix the electronic device The display screen, the mandrel is used to fix the display screen bracket and is passed through the pivot frame, and the pivot frame is used to assemble on the base of the electronic device, and the first gear is used to fix the mandrel and engage with the second gear, the pivot is passed through and fixed on the second gear, and the tripod is used for fixedly combining with the pivot. When in use, the hinge device of the elevating base drives the first gear to rotate through the display screen and the display bracket, so that the first gear simultaneously drives the second gear to unscrew the tripod to support the on one plane. In this way, the footrest is propped obliquely against the plane to solve the problem that the foot pad telescopic mechanism tends to be retracted into the base due to excessive weight.

However, since the first gear and the second gear are not located on the same axis line (that is, the two are not coaxial. The same below), and in order to allow the tripod to be accommodated in the base, the second gear It can only be arranged at the position where the base deviates from the outer side, so that the fulcrum of the tripod is arranged at a position that deviates from the outer side, resulting in the problem of poor supporting strength.
