Portable electronic device with adjustable air vents

technical field

The present invention relates to a portable electronic device, in particular to a portable electronic device with an adjustable air vent.

Background technique

With the advancement of manufacturing technology, various portable electronic devices, such as notebook computers or portable projectors, are becoming smaller and more convenient to carry. However, since the design of the portable electronic device is designed to be as light and thin as possible, the internal components are arranged quite closely. Electronic components will generate a lot of heat when they are in use, making the heat dissipation structure of the portable electronic device a very important part in the design of the device.

However, according to different usage conditions of the portable electronic device, the amount of heat generated inside the device is also different. Generally, it is difficult to adjust the heat dissipation performance of the heat dissipation vents of portable electronic devices according to the usage conditions. As a result, when the portable electronic device is operating at full capacity, the heat dissipation structure may not be able to meet higher than usual heat dissipation requirements.

Furthermore, different countries have different specifications for the openings of the housings of different portable electronic devices, and manufacturers have to manufacture products with specific specifications to meet the specifications of different regions, which is very troublesome. For example, for the protective structure of the opening of the notebook computer in Europe, the width of the air vent for heat dissipation must be limited to less than or equal to 1 mm, but there is no relevant regulation in other regions. As a result, manufacturers of notebook computers have to design different casings for notebook computers in accordance with European standards before they can be sold in Europe, which is very inconvenient. Moreover, the air vents with small openings also cause poor ventilation effects and affect heat dissipation.

In addition, the air vents for heat dissipation are generally open, so that dust, small garbage and even mosquitoes may enter the portable electronic device through the air vents. Foreign matter entering the electronic device may affect the performance of the internal electronic components, and in severe cases may cause damage to the portable electronic device.

Based on the above, the air vents for heat dissipation of portable electronic devices in the prior art cannot be adjusted according to the usage status of the electronic devices or the specific specifications of each country, and the open air vents may cause foreign matter to enter the electronic device and cause damage.

Contents of the invention

It can adjust the size of the tuyere through the mutually sliding shell and grille, so as to obtain different degrees of heat dissipation performance. And when the portable electronic device is not in use, the air vent can be closed to prevent foreign objects from entering the electronic device and causing damage.

The invention discloses a portable electronic device with an adjustable tuyere, which comprises a casing and a grid plate. The casing has an air vent area and a slide rail, wherein the slide rail is configured corresponding to the air vent area, and the air vent area has at least one air slit. The grid plate has at least one grid opening and a sliding block, and the sliding block is engaged with the slide rail so that the grid plate can slide between a first position and a second position. When the grid slides between the first position and the second position, the grid opening selectively completely overlaps, partially overlaps or does not overlap the ventilation slot.

The housing may additionally have multiple positioning components, and the grid plate may additionally have multiple matching components, wherein the positioning components correspond to the matching components. When the grid slides between the first position and the second position, part of the positioning component is fastened to the matching component.

According to an embodiment of the present invention, the grid plate may further have a handle portion, and the handle portion is exposed from the casing.
