Description
Technical Field
The invention relates to a notebook computer, in particular to a lifting structure of a notebook foot pad.
Background
In the prior art, the radiating opening of the notebook computer is arranged on the bottom surface of one end of the casing, which is close to the screen, and the distance between the radiating opening and the desktop is very short when the notebook computer is used. In order to avoid the influence of CPU overheat on the running speed of the computer after the notebook works for a long time, the service life of the computer is prolonged, one end of the bottom surface of the notebook close to a screen is required to be lifted to a certain height, a gap is formed between a heat dissipation port and a desktop or a table top for placing the notebook, and the notebook is used for ventilation and heat dissipation, so that the heat of the notebook can be timely and quickly dissipated.
In order to solve the problem of heat dissipation of a notebook, chinese patent document CN208722089U discloses a notebook computer with an automatic lifting height adjustment, which comprises a notebook main body, a bottom shell, a lifting groove, a pull rod mechanism, a cylinder push rod and a slide rail base. The both sides of drain pan are provided with the lift groove, and pull rod mechanism, cylinder push rod and slide rail base are laid in the lift inslot, and pull rod mechanism's last tie point and lower contact position all are provided with the round, and cylinder push rod one end is fixed in the inside in slide rail groove and is connected with the display screen lid linkage, and the shaft both ends of round are connected to the other end. With the display screen cover turned over, the cylinder push rod driven wheel rotated, and the wheel drove the pull rod mechanism shrink, drives drain pan and notebook main part height after the pull rod mechanism shrink and rises, and when the same reason closed display screen cover, the cylinder push rod drove the opposite direction motion of wheel, drives the pull rod mechanism and extends, and the pull rod mechanism highly descends after extending, and pull rod mechanism, cylinder push rod and slide rail base are retrieved into the lift groove. According to the technical scheme, although the problem of heat dissipation of the notebook is solved, the structure of the pull rod mechanism is complex, and the weight of the notebook is increased due to the fact that parts are more. When in use, the position of the shell where the keyboard is positioned is integrally improved, and the keyboard is not suitable for being applied to a common workbench, has poor applicability and is inconvenient to use.
In order to ensure that the notebook computer can fully dissipate heat in a use state by reserving a proper space between the shell and the workbench when the display screen cover is opened, the service life of the notebook computer is prolonged, the whole shell is not increased, meanwhile, the thickness of the notebook computer is automatically contracted when the notebook computer is closed, the notebook computer is convenient to store and package smoothly, the use is convenient, independent manual operation is not needed, and the thickness of the notebook computer shell is kept to be thinnest. The Chinese patent document CN209281287U discloses a wheel intermittent rotating mechanism of a shell lifting heat dissipation hinge, wherein the wheel intermittent rotating mechanism connects a screen cover plate with a shell and comprises a screen main shaft fixedly and rotationally arranged on the shell with the screen cover plate, a driving wheel coaxially fixedly arranged on the screen main shaft, a driven wheel rotationally fixed in the shell and meshed with the driving wheel, a cylinder on an eccentric wheel is coaxially fixedly connected on the driven wheel, and the screen main shaft rotates to drive the driving wheel and the driven wheel to rotate in the opening and closing processes of the screen, and the driven wheel drives the poking speed to reciprocate; the intermittent wheel rotating mechanism of the shell lifting heat dissipation hinge further comprises a poking wheel rotatably connected in the shell, an opening groove is formed in the poking wheel, and a cylinder body on the eccentric wheel can enter the opening groove of the poking wheel and slide along the opening groove. In the opening and closing process of the screen, the movement track of the cylinder on the eccentric wheel is crossed with the extending direction of the open slot to drive the poking wheel to rotate, and the cylinder on the eccentric wheel slides out and is inserted into the open slot to realize transmission; the wheel intermittent rotating mechanism of the shell jacking heat dissipation hinge further comprises a supporting leg serving as a shell jacking mechanism and rotatably installed on the side wall of the shell, and when the poking wheel rotates, the shell jacking mechanism rotates along with the poking wheel and stretches out of the shell to jack up the shell to realize heat dissipation. When the screen is opened to a specified angle, the shell lifting mechanism extends out of the shell to enable the shell to reach the maximum height, and meanwhile, the cylinder on the eccentric wheel is separated from the opening groove arranged on the poking wheel. In the process of continuously closing the screen, after the screen is closed to a certain angle (90 degrees), the cylinder on the eccentric wheel is meshed with the opening groove arranged on the poking wheel again, and the cylinder interacts with the poking wheel to drive the shell jacking mechanism to reversely move and retract to above the bottom surface of the shell, so that the reset of the shell of the notebook computer is realized.
However, the lifting of the shell position depends on the rotation of the shell lifting mechanisms positioned at two sides of the notebook computer, and the weight of the notebook computer, which is close to one end of the notebook screen when the shell is lifted to the highest position, can only provide support by means of the contact point between the shell lifting mechanism and the desktop, that is to say, the locking support state is realized by the superposition of the action direction between the gravity born by the rotating shaft of the shell lifting mechanism and the supporting force on the supporting point between the shell lifting mechanism and the desktop. However, in use, the notebook computer is inevitably moved on the desktop, and the movement often causes the casing lifting mechanism to deflect around the rotating shaft of the notebook computer, so that the acting direction between the gravity born by the rotating shaft of the casing lifting mechanism and the supporting force on the supporting point of the casing lifting mechanism and the desktop is no longer coincident, and the support is unstable. Obviously this requires a positioning mechanism to ensure the stability of its support.
