Description

Technical Field

[0001] The invention relates to the technical field of display screen housings, and in particular to a display screen with a distributed heat dissipation function. Background Art

[0002] The display screen is a high-resolution screen. Since it has more pixels, each pixel has a corresponding light-emitting element or control circuit behind it, which increases the overall energy consumption and generates more heat. If the heat is not dissipated in time or the heat dissipation effect is poor, it may cause performance degradation or hardware damage.

[0003] At present, it is more common to dissipate heat through a cooling fan, which has two main heat dissipation methods. One is the exhaust mode, in which the cooling fan is placed inside the display housing, and then the hot air accumulated in the display is extracted. For example, the patent with the authorization announcement number CN214757543U discloses a display screen with a heat dissipation function, including a display housing, a display back shell is arranged at the rear end of the display housing, a display screen, a circuit board and a heat sink are arranged inside the display housing, a fan box, a fan controller and an intelligent controller are arranged at the rear end of the heat sink, an electric rotating shaft and fan blades are arranged inside the fan box, a ventilation hole is arranged on the front face of the fan box, and a switch is arranged at the right end of the display housing. The fan is controlled to start by the fan controller to dissipate heat for the display screen. This method relies on the pressure difference between the inside and outside of the chassis and natural convection to inhale fresh air to supplement the extracted hot air, which may cause a certain positive pressure to form inside the chassis, slowing down the natural inflow speed of fresh cold air, which means that it takes a certain amount of time for the heat to be effectively diffused into the environment, that is, the heat dissipation method of the exhaust mode has the problem of slow heat dissipation speed.

[0004] The other is the intake mode, where the cooling fan is placed outside the display housing, and then cool air is blown directly to the display, which can directly take away the heat near the heat source, forming an effective heat exchange and accelerating local heat dissipation. It can be seen that this method can more directly cool the heat source quickly and improve the heat dissipation efficiency. However, although it solves the problem of slow heat dissipation in the exhaust mode, it is easy to dissipate the heat in the directly blown part, resulting in the problem of local heat dissipation, and there is a problem that the incoming gas is not easy to be discharged, causing the heat to easily accumulate inside the display housing and the display.

[0005] In order to dissipate heat quickly from a display screen and dissipate heat as a whole to prevent heat from accumulating inside the display screen, the present invention provides a display screen with a distributed heat dissipation function. Summary of the invention

DETAILED DESCRIPTION

It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0036] Embodiment 1: A display screen with distributed heat dissipation function, combined with the attached Figure 1 To Attachment Figure 7 , including a base 101, the upper part of the base 101 is rotatably connected to a shell 102, the front side of the shell 102 is fixedly connected to a display screen 1021, the side of the shell 102 away from the display screen 1021 is slidably connected to two sliding plates 103 along the front-back direction, a fan 104 for heat dissipation is rotatably connected in the sliding plate 103, a filter screen 105 is fixedly connected to the rear side of the sliding plate 103, a plurality of heat dissipation holes 106 are opened on the upper, lower, left and right sides of the shell 102, which are used to discharge heat from the upper, lower, left and right sides of the shell 102 to avoid heat accumulation inside, a side of the shell 102 close to the fan 104 is fixedly connected to a connecting plate 203 symmetrically distributed along the left and right sides of the shell 102, and a first connecting plate 203 symmetrically distributed along the left and right sides of the shell 102 is fixedly connected between the connecting plates 203 The guide plate 201 has guide grooves that are mirror-imaged on the left and right sides, which are used to guide the natural wind to the left and right sides respectively. The first guide plate 201 is fixedly connected to the second guide plate 202 that is symmetrically distributed up and down along the first guide plate 201. The sliding plate 103 and the fan 104 are both located on the rear side of the first guide plate 201, the second guide plate 202 and the connecting plate 203, and the rear side of the first guide plate 201, the second guide plate 202 and the connecting plate 203 has enough space for the sliding plate 103 and the fan 104 to move. The second guide plates 202 that are symmetrically distributed up and down are both provided with guide grooves. The guide grooves of the upper second guide plate 202 are used to guide the natural wind to the upper side, and the guide grooves of the lower second guide plate 202 are used to guide the natural wind to the lower side.

[0037] This is a display screen with distributed heat dissipation. Initially, the sliding plate 103 and the fan 104 are both stored in the housing 102. When the display screen 1021 needs to be used, since the fan 104 is close to the display screen 1021 at this time, the heat dissipation range is small. In order to expand the heat dissipation range, the sliding plate 103 needs to be slid to the side away from the display screen 1021, thereby driving the fan 104 to move to the side away from the display screen 1021. Then, the fan 104 is started, and the fan 104 introduces natural wind into the housing 102. The heat emitted by the display screen 1021 is exchanged with the incoming natural wind, and the heat inside the housing 102 The hot air is then dissipated into the air through the heat dissipation holes 106 on the four sides, so as to achieve the effect of distributed heat dissipation of the display screen 1021. The filter 105 can filter dust to prevent excessive dust from entering the inside of the shell 102. During the heat dissipation process, the first guide plates 201 on the upper and lower sides respectively guide the natural wind to the upper and lower sides, and the second guide plates 202 on the left and right sides respectively guide the natural wind to the left and right sides, so that the heat dissipation direction is more comprehensive, and the heat dissipation holes 106 on the four sides can accelerate the dissipation of heat. In this way, while ensuring rapid heat dissipation, the problems of local heat dissipation and heat accumulation are avoided.

[0038] Combined with Figure 8 To Attachment Fig.10 , also includes a first rotating shaft 303, the first rotating shaft 303 is rotatably connected to the shell 102, a first motor 302 is fixedly connected to the side of the shell 102 close to the cover 301, an output shaft of the first motor 302 is fixedly connected to the first rotating shaft 303, the first rotating shaft 303 is fixedly connected to the cover 301, the cover 301 is rotatably connected to connecting rods 304 symmetrically distributed along the cover 301, a sliding block 305 is slidably connected to the sliding plate 103 close to the adjacent connecting rod 304 in the up and down directions, and the sliding block 305 is rotatably connected to the adjacent connecting rod 304.

[0039] In order to prevent tiny flying insects, dust and the like from entering the housing 102 when not in use, it is necessary to block it with the cover 301. When in use, the first motor 302 is controlled to drive the first rotating shaft 303 to rotate, thereby driving the cover 301 to rotate, so that the cover 301 is automatically opened, which does not affect the entry of natural wind. When the cover 301 is opened, the cover 301 drives the sliding plate 103 to move outward automatically through the connecting rod 304, and there is no need to manually push the sliding plate 103 outward. When the use is completed, the first motor 302 is controlled to drive the first rotating shaft 303 to reverse, thereby driving the cover 301 to automatically close, and at the same time, the sliding plate 103 and the fan 104 are automatically stored in the housing 102 through the connecting rod 304.
