With the advancement of technology, the design of LCD TV outer shell pays more and more attention to the improvement of lightness, beauty and heat dissipation performance.

[0003] In order to overcome the above defects, prior art 1 (a Chinese patent with announcement number CN204554294U and announcement date 2015-08-12) discloses a TV housing, on the bottom surface of which at least one base and at least one receiving groove for receiving the base are provided; the base comprises a base fixed in the receiving groove and a foldable bracket assembly, the bracket assembly being hinged to the base; the bracket assembly comprises at least a first state point and a second state point; in the first state point, the bracket assembly is folded and received in the receiving groove; in the second state point, the bracket assembly is located outside the receiving groove and unfolded to support the TV housing. The utility model also discloses an LCD TV, a TV casing and an LCD TV, which makes it very convenient for the LCD TV to switch between a base support and a bracket support, solves the trouble of disassembling and assembling the base, and does not need to disassemble the base, thus avoiding the loss of the base. There is also prior art 2 (a Chinese patent with announcement number CN219018882U and announcement date 2023-05-12) a TV casing, which relates to the field of televisions, a TV casing, including a TV casing and a mounting plate, wherein a mounting groove is arranged at the front end of the TV casing, and a mounting groove is arranged around the mounting groove. A mounting bar, a heat dissipation fan and a heat dissipation block are arranged between the TV housing and the mounting plate, a hanging bar is also arranged inside the mounting groove, and a plurality of hanging columns are arranged on the hanging bar, so that the electronic components of the TV series can be installed inside the TV housing, and the display screen is rotatably hung on the mounting plate, and the mounting plate is fixed by the cooperation of the second mounting hole and the first mounting hole on the mounting bar, and the fixing method is simple and reliable, and the heat dissipation fan and the heat dissipation block can dissipate the heat generated by the operation of the TV, and when used specifically, the hanging columns on the hanging bar can be used to place electronic component assemblies, such as LED boards, etc.

[0004] Although the TV casing in the prior art can dissipate the heat generated by the TV by means of a cooling fan and a heat sink, it cannot accelerate the flow of air inside the casing during the heat dissipation operation. If it only relies on the cooling fan, the air flow speed inside the casing is poor and the heat dissipation efficiency is relatively low.

[0005] Therefore, we propose a cooling shell structure for a liquid crystal television to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a cooling shell structure for a liquid crystal television, so as to solve the problem that the TV shell on the market currently cannot accelerate the flow of air inside the shell when performing heat dissipation operation, and only relies on a heat dissipation fan, the air flow speed inside the shell is poor, and its heat dissipation efficiency is relatively low.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooling shell structure for a liquid crystal television, comprising a shell, a heat dissipation frame capable of dissipating heat and cooling is arranged on the rear side of the shell, and heat dissipation holes are opened on the left and right sides of the heat dissipation frame, a fixing plate is fixedly connected to the inner side of the heat dissipation frame, a guide mechanism is arranged inside the fixing plate, and the guide mechanism enables air convection through the deformation of the memory alloy arranged inside, a deformable tube body is fixedly connected at the corresponding position on the inner side of the heat dissipation hole, and an adjustment mechanism is arranged between the outer side of the deformable tube body and the inner side of the heat dissipation frame, and the adjustment mechanism changes the end shape of the deformable tube body through the deformation force of the memory alloy.

[0008] Preferably, the air guide mechanism includes a driving motor, the driving motor is fixedly connected to the inside of the heat dissipation frame, and the output end of the driving motor is fixedly connected to the cooling fan, a placement groove is opened on the inner side of the fixing plate, a start button is fixedly connected to the inside of the placement groove, and a memory alloy is fixedly connected to the side of the placement groove.

[0009] Preferably, the memory alloy is in contact with the start button when not deformed, and the start button is electrically connected to the drive motor, and the memory alloy is arranged in an "L"-shaped structure when viewed from the front.

[0010] Preferably, two groups of the fixing plates are symmetrically arranged about the center point of the heat dissipation frame, and the two groups of memory alloys are tilted from left to right toward the center of the heat dissipation frame after deformation.

[0011] Preferably, the adjusting mechanism includes a fixed seat, which is fixedly connected to the inside of the heat dissipation frame, and the inner side of the fixed seat is fixed to the outer side of the deformation tube body, and the other side of the outside of the deformation tube body is fixedly connected to the adjusting seat, and the adjusting seat is nested and connected to the outside of the fixed seat, the side of the adjusting seat is fixedly connected to a connecting plate, and a traction rope is fixedly connected between the upper part of the outermost adjusting seat and the memory alloy at the corresponding position of the side, a sliding groove is provided on the side of the heat dissipation frame, and a limiting rod is fixedly connected to the inside of the sliding groove, and a sliding block is nested and connected to the outside of the limiting rod, and the side of the sliding block is fixedly connected to the inner side of the connecting plate, and an auxiliary spring is fixedly connected between the inner side of the sliding block and the sliding groove.

[0012] Preferably, the connecting plate fixedly connects the three groups of adjustment seats into one group, and the memory alloy forms a sliding structure with the adjustment seat through a traction rope, the slider forms a sliding structure with the connecting plate and the limit rod, and the slider forms an elastic structure with the auxiliary spring and the slide groove.

[0013] Preferably, the opening of the left adjustment seat is set downward, and the opening of the right adjustment seat is set upward, the left adjustment seat squeezes the deformable tube body through the traction of the traction rope, and the right adjustment seat stretches the deformable tube body through the traction of the traction rope.

[0014] Preferably, the slider extends to the outside of the heat dissipation frame, and the outside of the slider is fixedly connected to a moving frame, and a cleaning sheet is provided on the inside of the moving frame, and an auxiliary hole is provided on the moving frame.

[0015] Preferably, the cleaning sheets are arranged in two groups symmetrically up and down about the center of each heat dissipation through hole, and the inner side of the cleaning sheet is in contact with the outer side of the filter screen arranged outside the heat dissipation through hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects: When the temperature inside the shell is high, the memory alloy senses the temperature change, thereby elastically deforming and expanding outward. The deformed and expanded memory alloy does not resist the start button set inside the placement slot. At this time, the start button is not subjected to force, thereby starting the drive motor electrically connected to it to move, so that the drive motor drives the cooling fan to rotate, thereby blowing air to cool the LCD TV.

[0017] When the memory alloys on the upper and lower sides are expanded outward, the memory alloy is set in an inclined state from left to right toward the center of the heat dissipation frame. When the heat dissipation fan is rotating, the outside wind enters the heat dissipation frame from the left heat dissipation through-hole, and its wind force is transmitted along the inclined portion of the memory alloy. When the wind force enters the heat dissipation frame from the right heat dissipation through-hole, its wind force will be blocked by the memory alloy and cannot flow smoothly. At this time, a pressure difference will be formed inside the heat dissipation frame, so that the wind force output by the heat dissipation fan enters from the left heat dissipation through-hole and is discharged from the right heat dissipation through-hole, thereby realizing air convection and accelerating heat dissipation.

[0018] When the memory alloy arranged on the upper side is deformed, the traction rope arranged on the outer side of the memory alloy is not subjected to tension at this time, so the adjusting seat is also not subjected to tension. The three groups of adjusting seats move downward synchronously under the driving action of the connecting plate. At this time, the adjusting seat and the fixed seat cooperate with each other to squeeze the deformable tube body on the left side, so that the end of the deformable tube body is deformed, thereby making the ventilation channel narrower. When the outside air enters the heat dissipation frame through the deformable tube body, due to the relatively narrow internal channel of the deformable tube body, the flow rate of the air will increase when passing through, thereby increasing the amount of external air entering and further improving the heat dissipation effect.

[0019] When the memory alloy arranged on the lower side is deformed, the memory alloy will exert tension on the traction rope arranged on the outer side, so that the adjustment seat moves downward. At this time, the downward-moving adjustment seat cooperates with the adjustment seat to deform the end of the deformation tube body, thereby increasing the ventilation channel, thereby further allowing the air carrying heat inside the heat dissipation frame to be better discharged to the outside, thereby accelerating heat dissipation.

[0020] When the connecting plate moves, it will synchronously drive the slider to slide along the outside of the limit rod. At the same time, the outer end of the slider will synchronously drive the moving frame to move, so that the cleaning sheet set on the inside of the moving frame will move synchronously. At this time, the cleaning sheet can clean the filter set on the outside of the heat dissipation through hole, thereby reducing dust adhering to the filter and affecting the air in and out.

[0025] When the temperature inside the shell 1 is high, the memory alloy 9 senses the temperature change, thereby elastically deforming and expanding outward. The deformed and expanded memory alloy 9 does not resist the start button 15 set inside the placement slot 16. At this time, the start button 15 is not subjected to force, thereby starting the drive motor 21 electrically connected to it to move, so that the drive motor 21 drives the cooling fan 2 to rotate, thereby blowing air to cool the LCD TV.

When the memory alloys 9 on the upper and lower sides are both expanded outward, the memory alloys 9 are arranged in an inclined state from left to right toward the center of the heat dissipation frame 20. When the heat dissipation fan 2 is rotating, when the external wind enters the heat dissipation frame 20 from the left heat dissipation through-hole 5, its wind force will be transported along the inclined portion of the memory alloy 9. When the wind force enters the heat dissipation frame 20 from the right heat dissipation through-hole 5, its wind force will be blocked by the memory alloy 9 and cannot flow smoothly. At this time, a pressure difference will be formed inside the heat dissipation frame 20, so that the wind force output by the heat dissipation fan 2 enters from the left heat dissipation through-hole 5 and is discharged from the right heat dissipation through-hole 5, thereby realizing air convection and accelerating heat dissipation.

[0027] Embodiment 3: Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The technical solution shown in the figure, the present invention provides the following technical solution: a cooling shell structure for a liquid crystal television, disclosing an adjustment mechanism, through which the ventilation channel at the end of the deformable tube body 8 can be deformed, so that air can quickly enter and discharge: the deformable tube body 8 is fixedly connected to the corresponding position on the inner side of the heat dissipation through hole 5, and an adjustment mechanism is arranged between the outer side of the deformable tube body 8 and the inner side of the heat dissipation frame 20, and the adjustment mechanism changes the end shape of the deformable tube body 8 through the deformation force of the memory alloy 9, and the adjustment mechanism includes a fixing seat 6, a fixing The seat 6 is fixedly connected to the inside of the heat dissipation frame 20, and the inner side of the fixed seat 6 is fixed to the outer side of the deformation tube body 8, and the other side of the outside of the deformation tube body 8 is fixedly connected with the adjustment seat 7, and the adjustment seat 7 is nested and connected to the outside of the fixed seat 6. The side of the adjustment seat 7 is fixedly connected with a connecting plate 10, and a traction rope 14 is fixedly connected between the upper part of the outermost adjustment seat 7 and the memory alloy 9 at the corresponding position of the side. The side of the heat dissipation frame 20 is provided with a slide groove 11, and the inside of the slide groove 11 is fixedly connected with a limit rod 18, and the outside of the limit rod 18 is nested. A slider 12 is connected, and the side of the slider 12 is fixedly connected to the inner side of the connecting plate 10, and an auxiliary spring 13 is fixedly connected between the inner side of the slider 12 and the slide groove 11. The connecting plate 10 fixedly connects the three groups of adjustment seats 7 into one group, and the memory alloy 9 forms a sliding structure with the adjustment seat 7 through a traction rope 14, the slider 12 forms a sliding structure with the limit rod 18 through the connecting plate 10, and the slider 12 forms an elastic structure with the slide groove 11 through the auxiliary spring 13, the opening of the left adjustment seat 7 is set downward, and the opening of the right adjustment seat 7 is set upward. The left adjusting seat 7 squeezes the deformable tube body 8 through the traction of the traction rope 14, and the right adjusting seat 7 stretches the deformable tube body 8 through the traction of the traction rope 14, the slider 12 extends to the outside of the heat dissipation frame 20, and the outside of the slider 12 is fixedly connected to the moving frame 4, and a cleaning sheet 17 is provided on the inside of the moving frame 4, and an auxiliary hole 19 is provided on the moving frame 4. The cleaning sheets 17 are symmetrically arranged in two groups about the center of each heat dissipation through hole 5, and the inner side of the cleaning sheet 17 is in contact with the outer side of the filter screen arranged on the outer side of the heat dissipation through hole 5.

[0028] When the memory alloy 9 arranged on the upper side is deformed, the traction rope 14 arranged on the outer side of the memory alloy 9 is not subjected to tension at this time, so the adjustment seat 7 is also not subjected to tension. The three groups of adjustment seats 7 move downward synchronously under the driving action of the connecting plate 10. At this time, the adjustment seat 7 cooperates with the fixed seat 6 to squeeze the deformable tube body 8 on the left side, so that the end of the deformable tube body 8 is deformed, thereby narrowing the ventilation channel. When the outside air enters the heat dissipation frame 20 through the deformable tube body 8, since the internal channel of the deformable tube body 8 is relatively narrow, the flow rate of the air will be accelerated when passing through, thereby increasing the amount of external air entering and further improving the heat dissipation effect. When the memory alloy 9 arranged on the lower side is deformed, the memory alloy 9 will apply tension to the traction rope 14 arranged on the outer side, thereby moving the adjustment seat 7 downward. At this time, the downwardly moved adjustment seat 7 cooperates with the adjustment seat 7 to deform the end of the deformable tube body 8, thereby increasing the ventilation channel, thereby further allowing the air carrying heat inside the heat dissipation frame 20 to be better discharged to the outside, thereby accelerating the heat dissipation.

[0029] When the connecting plate 10 moves, it will synchronously drive the slider 12 to slide along the outer side of the limiting rod 18.
