Description

Technical Field

[0001] The utility model relates to the technical field of television casings, in particular to a dust-proof television rear casing. Background Art

[0002] Since the back shell of most TVs is a closed design, the heat cannot be dissipated in time, so that the TV is always in a high temperature state when working, affecting the service life of the LCD TV.

[0003] In order to solve the above technical problems, most of the existing technologies have heat dissipation holes on the back shell to promote air circulation. However, the heat dissipation holes on the existing back shell have poor dustproof effect and are easy to allow dust to enter, thereby affecting the service life of internal electrical components, and need to be improved.

[0032] Example 1

[0033] Reference Figures 1 to 4 , which is the first embodiment of the utility model, provides a dust-proof TV rear shell, including a rear shell body 100, a dust-proof component 200 and a dust scraping component 300;

[0034] The rear shell body 100 is arranged at the rear side of the TV set, and the rear shell body 100 includes a front heat sink 101 and a rear heat sink 102, and the front heat sink 101 and the rear heat sink 102 are arranged on the rear shell body 100 at intervals in front and back;

[0035] The dustproof assembly 200 includes dustproof heat dissipation holes 201, dustproof heat dissipation columns 202 and dustproof shields 203 arranged on the rear shell body 100. The dustproof heat dissipation holes 201 and the dustproof heat dissipation columns 202 are arranged in front and back correspondence, and a dustproof shield 203 is arranged on the outer side of the front heat dissipation plate 101;

[0036] The rear shell body 100 is provided with an inner groove used in conjunction with the dustproof shield 203; a limiting slider 1021 is arranged on the side wall of the rear heat sink 102, and the rear shell body 100 is provided with a limiting slide groove used in conjunction with the limiting slider 1021, the limiting slider 1021 is connected to the limiting slide groove by sliding back and forth, and the spring 301 is arranged in the limiting slide groove; the dustproof heat dissipation holes 201 are provided with two groups, which are respectively arranged on the front heat sink 101 and the rear heat sink 102, and the two groups of dustproof heat dissipation holes 201 are staggered left and right.

[0037] In this embodiment: when the rear shell of the television is in use, the internal heat can be discharged through the dust-proof heat dissipation holes 201, so that the heat generated by the internal components of the television can be dissipated through the front heat dissipation plate 101 and the rear heat dissipation plate 102 on the rear shell body 100 to achieve heat dissipation function, thereby preventing the internal components of the television from being damaged; impurities in the external air can be filtered through the dust-proof cover 203 to prevent them from directly entering the inner cavity of the rear shell body 100.

[0038] Example 2

[0039] Reference Figures 3 to 6 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: the dustproof component 200 includes a dustproof heat dissipation column 202, and the dustproof heat dissipation hole 201 is arranged in a front-to-back correspondence with the dustproof heat dissipation column 202;

[0040] The dust scraping assembly 300 includes a spring 301 and a cleaning blade 302. The front heat sink 101 is fixedly connected to the rear shell body 100. The rear heat sink 102 is slidably connected to the rear shell body 100 through the spring 301. The dust shield 203 is fixed to the rear shell body 100 through bolts.

[0044] Since the rear heat sink 102 is connected to the rear shell body 100 by sliding forward and backward through the spring 301, when the bolts are removed, the dust-proof heat dissipation column 202 can be automatically inserted into the dust-proof heat dissipation hole 201 through the spring 301, and the dust in the dust-proof heat dissipation hole 201 can be scraped out through the cleaning scraper 302, and then the dust on the dust cover 203 and the cleaning scraper 302 can be cleaned uniformly, thereby greatly improving the dust resistance of the rear shell of the TV.
