Description

Technical Field

[0001] The invention relates to the technical field of notebook computer stands, in particular to a retractable and rotatable notebook computer stand. Background Art

[0002] Notebook computers, also known as "portable computers, handheld computers, PDAs or laptop computers", are characterized by their compact body. They are more portable than desktop computers and are small and easy to carry. They usually weigh 1-3 kg. The current development trend is that they are smaller and lighter, and more powerful. In order to reduce the size, notebook computers use liquid crystal displays. In addition to keyboards, they are also equipped with touch pads or touch points as positioning devices. Laptop stands are needed in the use of notebook computers. Laptop stands, also known as lazy stands, are used in a comfortable way. According to ergonomics, the design concept of man and machine is involved to obtain a comfortable computer experience. They are composed of a display stand and a notebook support.

[0003] However, the existing laptop computer stands have relatively simple functions and do not have a self-cleaning function. Since the laptop is exposed to the outside world for a long time, the surface of the display screen is prone to absorb dust due to static electricity. When the surface absorbs too much dust, it may affect people's normal operation and experience. Secondly, most laptop computer stands have fans added inside the bracket to dissipate heat for the laptop computer, but the wind energy generated by the fan rotation is negligible. When the laptop computer is working under load, the heat generated can convert the wind energy into hot air, which in turn leads to unsatisfactory heat dissipation effect.

[0004] In order to solve the above problems, we have made improvements and proposed a retractable and rotatable laptop computer stand. Summary of the invention

[0019] 2. The present invention can dissipate heat for the laptop computer placed on the top of the laptop computer stand by providing a heat dissipation mechanism, thereby reducing the situation in which heat is mixed with wind energy and converted into hot air due to the use of air cooling for heat dissipation, which in turn leads to poor heat dissipation effect. First, wind energy is generated by the operation of the fan to draw the outside air into the refrigeration box. The air is first filtered through a filter to absorb dust in the air. Subsequently, the air is cooled by a semiconductor refrigeration rod. The cooled air flows into the interior of the laptop computer stand through an air outlet pipe and then dissipates through the heat dissipation holes, thereby dissipating heat for the laptop computer placed on the top of the laptop computer stand and improving the service life of the laptop computer.

First, wind energy is generated by the operation of the fan 1207, and the outside air is sucked into the refrigeration box 1201, which reduces the use of air cooling for heat dissipation, resulting in the heat and wind energy being mixed with each other and converted into hot air, which in turn leads to poor heat dissipation effect. First, wind energy is generated by the operation of the fan 1207, and the outside air is sucked into the refrigeration box 1201. The air is first filtered through the filter 1208 to absorb dust in the air, and then the air is cooled by the semiconductor refrigeration rod 1210. The cooled air flows into the interior of the laptop computer placement rack 2 through the air outlet pipe 1205, and then dispersed through the heat dissipation hole 6, so as to dissipate the heat of the laptop computer placed on the top of the laptop computer placement rack 2 and improve the service life of the laptop computer.
