[0002] In-vehicle displays are divided into two types. One is the TV placed on the bus for viewing, which is essentially an in-vehicle TV. The other is small-sized in-vehicle displays with sizes of 3.5 inches, 4.3 inches, 7 inches, and 9 inches. Generally, they have two video inputs. One can be connected to the in-vehicle DVD, and the other is connected to the in-vehicle camera for reverse image. Some also have MP5 video playback and Bluetooth functions. It is a display that can be used on automotive similar moving tools and is convenient for use during vehicle movement. Simply put, in-vehicle TV is the mobile reception of digital TV (the difference from digital TV), mainly including a set-top box, a liquid crystal display screen, an antenna, an in-vehicle power supply, etc. In order to facilitate installation and use, various styles of in-vehicle mobile TV products have been developed, such as desktop in-vehicle TVs, baffle in-vehicle TVs, roof-suction in-vehicle TVs, rearview mirror displays, etc.

A second transmission shaft is arranged at the end of the first transmission belt away from the first transmission shaft. A driving bevel gear is arranged on one side of the second transmission shaft. The driving bevel gear is meshed and connected with an exhaust component arranged inside the protective main housing;

[0013] The exhaust component includes a transmission column and a driven bevel gear arranged at one end of the transmission column. The driven bevel gear is meshed and connected with the driving bevel gear. A connecting bearing is arranged in the middle of the transmission column.

[0018] Another technical solution proposed by the present invention: providing an implementation method of an in-vehicle liquid crystal display that can autonomously cool based on the Internet of Things, including the following steps:

[0019] S1: Pry open the threaded sleeve, and then insert the cooling spray can into the threaded sleeve. At this time, the cooling spray can is clamped by the threaded sleeve, and then rotate the hidden rotating ring so that the cooling spray mechanism is threadedly connected with the protective main housing. After that, hide the hidden rotating ring;

[0020] S2: When the temperature sensor senses that the temperature inside the protective main housing is too high, the in-vehicle liquid crystal display host will control the servo motor to start, thereby driving the driving gear to rotate clockwise. Since the driving gear is meshed and connected with the transmission rack, the traction member will move upward, and then the push head will push the output end of the cooling spray can, and the cooling spray can will spray out cooling gas, and the automatic cooling spray is completed;

[0021] S3: After the push head pushes the cooling spray can to spray out a certain amount of gas, the in-vehicle liquid crystal display host will control the servo motor to drive counterclockwise, thereby driving the first transmission shaft to rotate, and then driving the second transmission shaft to rotate through the first transmission belt. The rotation of the second transmission shaft causes the driving bevel gear to drive the transmission column to rotate, and then the exhaust fan blade rotates. At this time, the exhaust fan blade exhausts outward;

[0022] S4: While the servo motor drives the exhaust assembly to exhaust, it will drive the third transmission shaft to rotate, which in turn drives the fourth transmission shaft to rotate, and then drives the transmission gear to rotate. Since the driven gear and the transmission gear can be meshed, and the transmission gear is provided with a half rack, it will drive the driven gear to rotate, and then drive the transmission rod to move upward. At this time, the push rod will push the closing plate to rotate, so that there is a gap between the closing plate and the protective main housing, so that the cold air moves upward under the exhaust effect of the exhaust assembly, and then under the effect of the longitudinally arranged guide plate, the cold air flows evenly on one side of the heat conduction plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. For the vehicle-mounted liquid crystal display screen capable of autonomous cooling and its method based on the Internet of Things proposed by the present invention, pry open the threaded sleeve, and then insert the cooling spray can into the threaded sleeve. At this time, the cooling spray can is clamped by the threaded sleeve, and then rotate the hidden rotating ring to thread-connect the cooling spray mechanism with the protective main housing. After that, hide the hidden rotating ring. The installation is completed. The installation operation is simple, and the hidden rotating ring does not affect the overall occupied space of the vehicle-mounted liquid crystal display screen. When it is necessary to replace the cooling spray mechanism, pick out the hidden rotating ring and operate in the reverse direction to replace the cooling spray can. The replacement operation is also simple and convenient, improving the overall use flexibility.

[0025] 2. For the vehicle-mounted liquid crystal display screen capable of autonomous cooling and its method based on the Internet of Things proposed by the present invention, when the temperature sensor senses that the temperature inside the protective main housing is too high, the vehicle-mounted liquid crystal display screen host will control the servo motor to start, which in turn drives the driving gear to rotate clockwise. Since the driving gear is meshed with the transmission rack, it will make the traction member move upward, and then make the push head push the output end of the cooling spray can, and the cooling spray can sprays out the cooling gas, and the automatic cooling spray is completed.

[0026] 3. For the vehicle-mounted liquid crystal display screen capable of autonomous cooling and its method based on the Internet of Things proposed by the present invention, after the push head pushes the cooling spray can to spray out a certain amount of gas, the vehicle-mounted liquid crystal display screen host will control the servo motor to drive counterclockwise, which in turn drives the first transmission shaft to rotate, and then drives the second transmission shaft to rotate through the first transmission belt. The rotation of the second transmission shaft makes the driving bevel gear drive the transmission column to rotate, and then makes the exhaust fan blade rotate. At this time, the exhaust fan blade exhausts outward. Under the flow of the air current, the gas sprayed out by the cooling spray can is restricted by the guide plate and flows in an S shape on one side of the heat conduction plate, so as to quickly cool the vehicle-mounted liquid crystal display screen host comprehensively and improve the overall cooling effect.

[0027] 4. For the vehicle-mounted liquid crystal display screen capable of autonomous cooling and its method based on the Internet of Things proposed by the present invention, while the servo motor drives the exhaust component to exhaust, it will drive the third transmission shaft to rotate, and then drive the fourth transmission shaft to rotate, and then drive the transmission gear to rotate. Since the driven gear and the transmission gear can be meshed, and the transmission gear is provided with a half rack, it will drive the driven gear to rotate, and then drive the transmission rod to move upward. At this time, the push rod will push the closing plate to rotate, so that a gap is generated between the closing plate and the protective main housing, enabling the cold air to move upward under the exhaust effect of the exhaust component. Then, under the effect of the longitudinally arranged guide plate, the cold air uniformly flows on one side of the heat conduction plate, thereby comprehensively and quickly cooling the main body of the vehicle-mounted liquid crystal display screen and improving the overall cooling effect.

[0041] In order to solve the technical problem that the existing car LCD screen uses fans to continue to dissipate heat, but in the hot summer, the air temperature of the external environment is less stable than that of the LCD screen, and even high-speed air flow is difficult to achieve autonomous rapid cooling. Over time, the service life of the car LCD screen will be shortened. Please refer to Figure 1 and Figure 6 , providing the following technical solutions:

[0044] The cooling spray mechanism 3 includes a cooling spray can 31 and a threaded sleeve 32 clamped and wrapped around the outside of the cooling spray can 31. The threaded sleeve 32 is provided with a notch, and a hidden rotating ring 33 is arranged at the upper end of the threaded sleeve 32.

[0045] Specifically, pry open the threaded sleeve 32, then insert the cooling spray can 31 into the threaded sleeve 32. At this time, the cooling spray can 31 is clamped by the threaded sleeve 32. Then rotate the hidden rotating ring 33 to make the cooling spray mechanism 3 threadedly connected with the protective main housing 1. After that, hide the hidden rotating ring 33. The installation is completed. The installation operation is simple, and the hidden rotating ring 33 does not affect the overall occupied space of the in-vehicle liquid crystal display screen. When it is necessary to replace the cooling spray mechanism 3, pry out the hidden rotating ring 33 and operate in the reverse direction to replace the cooling spray can 31. The replacement operation is also simple and convenient, improving the overall use flexibility.

[0046] The cooling spray start component 4 includes a guide rod 41 and a traction piece 42 arranged outside the guide rod 41. A transmission rack 43 is arranged on one side of the traction piece 42. A push head 44 is arranged at the upper end of the traction piece 42. The push head 44 corresponds to the output end of the cooling spray can 31.

[0048] Specifically, when the temperature sensor 13 senses that the temperature inside the protective main housing 1 is too high, the in-vehicle LCD display host 2 will control the servo motor 51 to start, thereby driving the driving gear 52 to rotate clockwise. Since the driving gear 52 is meshed and connected with the transmission rack 43, the traction member 42 is moved upward, and then the pushing head 44 pushes the output end of the cooling spray can 31, and the cooling spray can 31 sprays out the cooling gas, completing the automatic cooling spray.

[0051] Specifically, after the pushing head 44 pushes the cooling spray can 31 to spray out a certain amount of gas, the in-vehicle LCD display host 2 will control the servo motor 51 to drive counterclockwise, thereby driving the first transmission shaft 53 to rotate, and then driving the second transmission shaft 55 to rotate through the first transmission belt 54. The rotation of the second transmission shaft 55 causes the driving bevel gear 56 to drive the transmission column 571 to rotate, and then the exhaust fan blade 575 to rotate. At this time, the exhaust fan blade 575 exhausts outward. Under the flow of the air current, the gas sprayed out by the cooling spray can 31 is restricted by the guide plate 15 and flows in an S shape on one side of the heat conducting plate 14, thereby quickly cooling the in-vehicle LCD display host 2 comprehensively and improving the overall cooling effect.

Then rotate the hidden rotating ring 33 so that the cooling spray mechanism 3 is threadedly connected to the protective main housing 1. After that, hide the hidden rotating ring 33;

[0067] Step 2: When the temperature sensor 13 senses that the temperature inside the protective main housing 1 is too high, the in-vehicle liquid crystal display host 2 will control the servo motor 51 to start, thereby driving the driving gear 52 to rotate clockwise. Since the driving gear 52 is meshed and connected to the transmission rack 43, the traction member 42 is moved upward, and then the pushing head 44 pushes the output end of the cooling spray can 31, and the cooling spray can 31 sprays out cooling gas, and the automatic cooling spray is completed;

[0068] Step 3: After the pushing head 44 pushes the cooling spray can 31 to spray out a certain amount of gas, the in-vehicle liquid crystal display host 2 will control the servo motor 51 to drive counterclockwise, thereby driving the first transmission shaft 53 to rotate, and then driving the second transmission shaft 55 to rotate through the first transmission belt 54. The rotation of the second transmission shaft 55 causes the driving bevel gear 56 to drive the transmission column 571 to rotate, and then causes the exhaust fan blade 575 to rotate. At this time, the exhaust fan blade 575 exhausts outward;

[0069] Step 4: While the servo motor 51 drives the exhaust assembly 57 to exhaust, it will drive the third transmission shaft 61 to rotate, then drive the fourth transmission shaft 63 to rotate, and then drive the transmission gear 64 to rotate. Since the driven gear 712 can be meshed with the transmission gear 64, and the transmission gear 64 is provided with a half rack, the driven gear 712 is driven to rotate, and then the transmission rod 713 is driven to move upward. At this time, the push rod 715 pushes the closing plate 72 to rotate, so that a gap is generated between the closing plate 72 and the protective main housing 1, so that the cold air moves upward under the exhaust effect of the exhaust assembly 57, and then under the effect of the longitudinally arranged guide plate 15, the cold air flows uniformly on one side of the heat conducting plate 14.
