1. Technical Field
The present disclosure relates to electronic devices, and particularly to an electronic device with a covering plate.
2. Description of Related Art
Electronic devices, such as computers, include a number of heat generating components, such as a CPU. The components generate different heat flux when they work under different states. Temperatures of the electronic devices may continue to rise as a working time of the number of heat generating components increases. Generally, users increase a rotation speed of a cooling fan to cool the electronic devices. However, increases of the rotation speed increasing may be noisy and consume more energy. Therefore, an improved electronic device may be desired.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
The covering plate 200 includes a plate body 201 and a plurality of limiting portions 204 located on the plate body 201. In one embodiment, the plate body 201 is circular, and each of the plurality of the limiting portions 204 has an “L” shaped. A size of the plate body 201 is substantially equal to a size of the cooling opening 16. The plate body 201 defines an installation slot 202 in a central portion of the plate body 201. The plurality of limiting portions 204 are arranged in a circle of the plate body 201 of equidistance.
The rack 210 is a strip. A plurality of teeth 211 are located on a side surface of the rack 210.
The first installation member 220 includes two first side plates 221. Each of the two first side plates 221 defines a first pivoting hole 2212. A first locking piece 223 extends from each of the two first side plates 221. The first locking piece 223 defines a first locking hole 2232. In one embodiment, the first locking piece 223 is substantially perpendicular to the two first side plates 221.
The gear member 230 defines an installation hole 231. The gear member 230 may be geared with the teeth 211 of the rack 210.
The first turntable 250 defines a first mounting hole 251. The second turntable 260 defines a second mounting hole 261. In one embodiment, the first turntable 250 and the second turntable 260 are circular. A diameter of the first turntable 250 is greater than a diameter of the second turntable 260. The belt 270 may surround the first turntable 250 and the second turntable 260 and rotate together with the first turntable 250 and the second turntable 260.
The second installation member 280 includes two second side plates 281. Each of the two second side plates 281 defines two second pivoting holes 2812. A second locking piece 283 extends from each of the two second side plates 281. The second locking piece 283 defines a second locking hole 2832. In one embodiment, the second locking piece 283 is substantially perpendicular to the two second side plates 281.
The motor 290 includes a motor body 291 and a rotating shaft 293 attached to the motor body 291. The rotating shaft 293 is rotatable along a clockwise direction or an anticlockwise direction when the motor 290 is powered on. A cross-section of the rotating shaft 293 is substantially equal to a cross-section of the pivoting shaft 240.
A first locking member (not shown), such as a screw, is inserted into the first locking hole 2232 and the first shell 12 or the second shell 14, to secure the first installation member 220 to the first shell 12 or the second shell 14. A second locking member (not shown), such as a screw, is inserted into the second locking hole 2832 and the first shell 12 or the second shell 14, to secure the second installation member 280 to the first shell 12 or the second shell 14. A first end of the rack 210 is engaged in the installation slot 202. A second of the rack 210, opposite to the first end, is located between the two first side plates 221 and geared with the gear member 230. The first shell 12 is secured to the second shell 14, and the first cutout 121 and the second cutout 141 together form a circular cooling opening 16. The covering plate 200 is located in the cooling opening 16 and covers the cooling opening 16. In this position, the covering plate 200 is located in an initial position. The temperature sensing module 30 is connected to the covering module 20. The temperature sensing module 30 may detect a temperature of the housing 10 and transmit a control signal to the covering module 20.
In use, the temperature sensing module 30 may detect a temperature of the housing 10 and output a control signal to the covering module 20. When the temperature is lower than a pre-set temperature, the motor 290 of the covering module 20 does not work, and the covering plate 200 is in the initial position. In this position, the housing 10 is closed and beautiful. When the temperature is equal or greater than the pre-set temperature, the control signal controls the motor 290 to start to operate, the rotating shaft 293 is rotated along the clockwise direction and rotates the first turntable 250 and the second turntable 260 to rotate along the clockwise direction. The second turntable 260 rotates the pivoting shaft 240 and the gear member 230 to rotate along the clockwise direction. The gear member 230 urges the rack 210 to move upwards. The covering plate 200 is moved upwards together with the rack 210 and located above the cooling opening 16. In this position, the covering plate 200 is located in an open position, the cooling opening 16 opens and heated air can flow out of the housing 10 from the cooling opening. The pivoting shaft 240 and the rotating shaft 293 are substantially perpendicular to a sliding direction of the covering plate and the rack 210, and the pivoting shaft 240 is substantially parallel to the rotating shaft 293. The limiting portion 204 can be engaged with an inner surface of the housing 10 when the covering plate 200 is moved upwards, to restrict the covering plate 200 from moving to a limited height. When the temperature falls lower than the pre-set temperature, the motor 290 is rotated anticlockwise to rotate the gear member 230 anticlockwise. The gear member 230 urges the rack 210 to move downwards to pull the covering plate 200 to cover the cooling opening 16. In this position, the cooling opening 16 is closed, and the covering plate is located in the initial position.
In other embodiments, the covering plate 200 can be automatically pushed by another pushing assembly, different from the pushing assembly 300, according to the temperature of the housing 10. The pushing assembly 300 includes the motor 290, the first turntable 250, the second turntable 260, the belt 270, the first installation member 220, the second installation member 280, the gear member 230, the pivoting shaft 240, and the rack 210.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes ay be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure, to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
