Description

Technical Field

[0001] This utility model relates to the field of laptop accessories, specifically a laptop cooling pad. Background Technology

[0002] A laptop cooling stand is an auxiliary device used to improve the heat dissipation performance of a laptop. By increasing airflow and raising the laptop's height, it helps maintain a lower temperature during prolonged use, thereby improving performance and lifespan. Increased airflow quickly dissipates heat generated by the laptop. Some stands are made of metal, which has better thermal conductivity. Raising the laptop's height also brings the screen to eye level, reducing pressure on the neck and lower back and protecting the spine.

[0003] However, since most current laptop stands rely on friction to support the laptop against the stand surface, instability can easily occur when the laptop is thick and the angle of the diagonal brace is adjusted. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a laptop cooling pad that solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a laptop cooling base, including an outer bracket frame, a support pad inside the outer bracket frame, a wavy protrusion arrayed on the upper surface of the support pad, limit sliders installed at both ends of the support pad, limit grooves opened on the inner sidewall of the outer bracket frame corresponding to the positions of the wavy protrusions, a limit mounting sleeve installed at the center of the inner side of the outer bracket frame, a bevel gear disk above the limit mounting sleeve, a lifting screw installed inside the bevel gear disk, a bevel gear on one side of the bevel gear, a crank handle installed on the outer end of the bevel gear via a connecting rod, and a limit plate installed on the outer end of the outer bracket frame.

[0006] As a further improvement of this utility model: cooling fans are installed on both sides of the limiting installation sleeve inside the outer bracket frame, and the internal array of the support pad has cooling through holes.

[0007] As a further embodiment of this utility model: a placement base is provided directly below the outer bracket frame, a rotating ear plate is installed on the upper surface of the placement base on the side away from the rotating crank handle, a support slot is installed on the upper surface of the placement base, and a support rod is installed on the lower surface of the outer bracket frame corresponding to the position of the support slot.

[0008] As a further embodiment of this utility model: the outer bracket frame has a placement notch on the side near the rotating crank handle, and the support pad is slidably connected to the outer bracket frame through the limiting slider.

[0009] As a further embodiment of this utility model: the bevel gear disc is rotatably connected to the limiting mounting sleeve, and the lifting screw is movably connected to the bevel gear disc through meshing.

[0010] As a further improvement of this utility model: the bevel gear is movably connected to the bevel gear disc, and the limiting plate is an L-shaped structural component.

[0011] As a further improvement of this utility model: the heat dissipation through hole is connected to the support pad, and the cooling fan is connected to an external driving power supply.

[0012] As a further improvement of this utility model: a movable shaft is installed between the outer bracket frame and the rotating ear plate, and the support rod is engaged with the support slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The bevel gear and bevel gear disk mesh and rotate, controlling the lifting screw to mesh and rotate upward. Therefore, the lifting screw pushes the support pad vertically upward inside the outer bracket frame, thus pushing the laptop keyboard part upward. Under the action of the limiting plate set on the outside of the outer bracket frame, it is limited and clamped to ensure the stability of the support.

[0014] The array of wavy protrusions on the upper surface of the support pad increases the friction between the pad and the laptop. Meanwhile, the recessed areas and ventilation holes facilitate airflow when the cooling fan is blowing air. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5 As shown, this embodiment provides a laptop cooling pad, including an outer frame 1. A support pad 2 is disposed inside the outer frame 1. Corrugated protrusions 202 are arrayed on the upper surface of the support pad 2. The support pad 2 is slidably connected to the outer frame 1 via limiting sliders 201. Limiting sliders 201 are installed at both ends of the support pad 2. Limiting grooves are formed on the inner sidewall of the outer frame 1 corresponding to the positions of the corrugated protrusions 202. A limiting mounting sleeve 803 is installed at the center of the interior of the outer frame 1. A [missing information - likely a design feature] is provided above the limiting mounting sleeve 803. A bevel gear disc 802 is provided, which is rotatably connected to a limiting mounting sleeve 803. A lifting screw 804 is installed inside the bevel gear disc 802, which is engaged and movably connected to the bevel gear disc 802. A bevel gear 801 is provided on one side of the bevel gear disc 802, which is engaged and movably connected to the bevel gear disc 802. A rotating handle 8 is installed on the outer end of the bevel gear 801 through a connecting rod. A placement notch is opened on the side of the outer support frame 1 near the rotating handle 8. A limiting plate 7 is installed on the outer end of the outer support frame 1. The limiting plate 7 is an L-shaped structural component.

[0019] like Figure 2-3As shown, in this embodiment, cooling fans 9 are installed on both sides of the limiting installation sleeve 803 inside the outer bracket frame 1. The cooling fans 9 are connected to an external driving power supply. The internal array of the support pad 2 has heat dissipation through holes 203, which are connected to the support pad 2. A placement base 3 is provided directly below the outer bracket frame 1. A rotating ear plate 4 is installed on the upper surface of the placement base 3 on the side away from the rotating handle 8. A movable shaft is installed between the outer bracket frame 1 and the rotating ear plate 4. A support slot 5 is installed on the upper surface of the placement base 3. A support rod 6 is installed on the lower surface of the outer bracket frame 1 at the position corresponding to the support slot 5. The support rod 6 is engaged with the support slot 5.

[0020] The working principle of this utility model is as follows: When in use, after unfolding the laptop screen, the laptop base is inserted into the outer frame 1 from the side with the rotating handle 8. A torque is applied to the rotating handle 8, causing the connecting rod to rotate the bevel gear 801. The bevel gear 801 and bevel gear disc 802 mesh and rotate, controlling the bevel gear disc 802 to mesh with the internal lifting screw 804 and rotate upwards. Therefore, the lifting screw 804 pushes the support pad 2 vertically upwards inside the outer frame 1, thereby pushing the laptop keyboard upwards. The outer support frame 1 is clamped by the limiting plate 7. After the outer support frame 1 is rotated by the pivot at the position of the rotating ear plate 4, the support rod 6 installed below the outer support frame 1 is rotated and then the support rod 6 is locked in the support slot 5 at different positions above the base 3. The external power supply of the cooling fan 9 is used to cool the laptop. The wavy protrusions 202 arrayed on the upper surface of the support pad 2 can increase the friction between the support and the laptop. At the same time, the recessed position and the heat dissipation holes 203 can facilitate the airflow under the blowing action of the cooling fan 9.
