[0002] To put it simply, the LCD module is a screen plus a backlight component. The display component of an LCD TV is the LCD module, which is equivalent to the cathode ray tube in a CRT. Other parts include power circuits, signal processing circuits, etc. The module is mainly divided into a screen and a backlight component. The two parts are assembled together, but they work independently.

[0003] The prior art provides a high-brightness outdoor liquid crystal display module (Announcement No. CN215069065U), which includes a heat dissipation mechanism, a fixing mechanism and a display mechanism.

[0004] The above-mentioned high-brightness outdoor LCD display module only provides the heat dissipation function of the LCD module during actual use.

At the same time, the LCD display module that runs for a long time may generate a certain amount of heat, which may require an additional cooling system to cope with, further increasing energy consumption. Therefore, we need to propose an induction energy-saving outdoor LCD display module. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides a technical solution:

[0025] The induction energy-saving outdoor liquid crystal display module comprises a housing 1, a liquid crystal display module body 3 is arranged inside the housing 1, a mounting box 19 is fixedly installed on the side of the housing 1, a controller 20 is fixedly installed inside the mounting box 19, and the controller 20 is electrically connected to the control system inside the liquid crystal display module body 3;

[0026] It also includes an induction installation component, which includes a mounting block 4 and a human body heat sensing detector 5. The human body heat sensing detector 5 is fixedly mounted at the bottom of the mounting block 4, and the human body heat sensing detector 5 is electrically connected to the controller 20;

[0027] The induction mounting assembly further includes a mounting seat 6 and a fixing block 7, wherein the fixing block 7 is fixedly connected to both sides of the mounting block 4, and the mounting seat 6 is fixedly mounted on the side of the mounting block 4;

[0028] It is worth noting that fixing screws are provided on the mounting seat 6 and the fixing block 7. The mounting seat 6 and the fixing block 7 can be used to select the case mode of the induction mounting component. The fixing block 7 can be used to fix the induction mounting component on the wall with the fixing screws, and the mounting seat 6 can be used to fix the induction mounting component on the columnar object with the fixing screws.

[0029] A mounting frame 2 for protecting the liquid crystal display module body 3 is fixedly mounted on the side of the housing 1. A heat conducting plate 8 is arranged inside the housing 1. The heat conducting plate 8 is in contact with the heating element inside the liquid crystal display module body 3.

[0030] It is worth noting that the heat dissipated by the heating element inside the liquid crystal display module body 3 can be conducted through the heat conducting plate 8;

[0031] A fixing box 12 is fixedly installed on the side of the housing 1, and a heat sink 9 is fixedly installed inside the fixing box 12. A plurality of heat conducting sheets 10 are arranged in a rectangular array on one side of the heat sink 9, and the plurality of heat conducting sheets 10 are all attached to the heat conducting sheet 8.

[0032] In this embodiment, in order to better dissipate heat for the outdoor liquid crystal display module, a temperature detection sensor 22 is fixedly installed inside the fixed box 12, and the temperature detection sensor 22 is electrically connected to the controller 20. The temperature detection sensor 22 can detect the heat emitted by the heat sink 9 and the heat sink 11. When it is detected that the heat emitted by the heat sink 9 and the heat sink 11 is too high, the controller 20 controls the cooling fan 15 to work to dissipate heat for the heat sink 9 and the heat sink 11;

[0033] The other side of the heat sink 9 is provided with a plurality of heat sinks 11 in a circular array, and heat dissipation channels 21 are left between adjacent heat sinks 11;

[0034] It is worth mentioning that the heat dissipation efficiency of the heat dissipation plate 9 and the heat dissipation fins 11 is accelerated by the heat dissipation fins 11 arranged in a ring array;

[0035] Specifically, when the cooling fan 15 blows the outside air toward the heat sink 9 and the heat sink 11, the air can diffuse outward along the heat sink channel 21 between the heat sink 11, thereby increasing the contact area between the air and the heat sink 9 and the heat sink 11, thereby accelerating the heat dissipation efficiency of the heat sink 9 and the heat sink 11, and then the air can be discharged through the heat dissipation port 17;

[0036] The side of the fixing box 12 is connected with a mounting pipe 13, a fixing frame 14 is fixedly installed inside the mounting pipe 13, a cooling fan 15 is fixedly installed on the side of the fixing frame 14, and one end of the mounting pipe 13 is inclined;

[0037] It is worth noting that, by setting one end of the mounting pipe 13 at an angle, rainwater can be effectively prevented from falling into the fixing box 12 through the mounting pipe 13;

[0038] Both sides of the fixed box 12 are provided with heat dissipation openings 17, and a protective net 18 is provided inside the heat dissipation openings 17. Both sides of the fixed box 12 are fixedly installed with rain shielding frames 16 for protecting the heat dissipation openings 17 from rain.

[0039] It is worth mentioning that the protective net 18 can prevent debris from falling into the fixed box 12 through the heat dissipation opening 17, and the rain shield 16 can prevent rainwater from falling into the fixed box 12 through the heat dissipation opening 17;

[0040] In specific use, the sensing installation component can first be installed on the roadside near the outdoor liquid crystal display module. When a person passes by and enters the detection area, after the human body heat sensing detector 5 detects the person, the controller 20 controls the liquid crystal display module body 3 to start working. At this time, real-time information or advertising content can be displayed through the liquid crystal display module. When the human body heat sensing detector 5 detects that the person leaves the detection area, the controller 20 controls the liquid crystal display module body 3 to close, thereby realizing the automatic switch of the liquid crystal display module.

[0041] When the weather is hot or the liquid crystal display module works for a long time, the heat inside the shell 1 is transferred to the heat sink 9 and the heat sink 11 through the heat conducting plate 8 and the heat conducting sheet 10. The temperature detection sensor 22 can detect the heat emitted by the heat sink 9 and the heat sink 11. When it is detected that the heat emitted by the heat sink 9 and the heat sink 11 is too high, the controller 20 controls the cooling fan 15 to work, so that the cooling fan 15 blows the outside air to the heat sink 9 and the heat sink 11, thereby accelerating the heat dissipation efficiency of the heat sink 9 and the heat sink 11.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
