Description

Technical Field

[0001] This utility model relates to the field of control device technology, specifically to a vehicle instrument multimedia control device. Background Technology

[0002] The automotive instrument panel multimedia control unit is a device used in modern automobiles to control and manage multimedia functions. Its main functions include multimedia entertainment control, navigation, vehicle information display, and vehicle settings. It is generally divided into physical button type, touch screen type, and voice control type.

[0003] Touchscreen automotive instrument multimedia control devices generally consist of components such as a housing, display screen, sensors, and processor. When in use, the sensors detect the location or method of clicking the screen, and then transmit the detected information to the processor for processing. The processed information is then displayed on the display screen.

[0004] Traditional touchscreen automotive instrument multimedia control devices tend to generate a lot of heat during operation due to the processor and multiple sensors inside. Because the control device is relatively small, its internal heat dissipation efficiency is relatively low, and the slow heat dissipation can affect the processing efficiency of the processor and the sensing of the sensors. At the same time, being in a high-temperature environment continuously can reduce the lifespan of the processor and sensors. Utility Model Content

A heat-conducting plate is fixedly connected to the outside of the end of the cooling oil pipe away from the cooling oil tank, and the end of the heat-conducting plate away from the cooling oil pipe is fixedly connected to an electronic component.

[0011] The above technical solution utilizes a heat-conducting plate to absorb the heat generated by the operation of electronic components, while simultaneously using coolant flowing within the cooling oil pipes to dissipate the heat absorbed by the heat-conducting plate.

[0016] As a preferred embodiment of the above technical solution, a gear is sleeved on the outer side of the first toothed column and meshes with a toothed belt, and a gear on the inner side of the toothed belt away from the first toothed column meshes with a second toothed column, and the inner side of the second toothed column is rotatably connected to the outer side of the cooling oil pipe.

[0017] The above technical solution allows the gears on both sides to rotate through the meshing of the toothed belt and the second toothed column.

[0018] As a preferred embodiment of the above technical solution, a rotating cylinder is fixedly connected to one end of the second toothed column, and a fan blade is fixedly connected to the end of the rotating cylinder away from the second toothed column.

[0019] The above technical solution utilizes the rotation of the drum and fan blades to accelerate the airflow on the surface of the cooling oil pipe.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a vehicle instrument multimedia control device, including a housing 1, a display screen 11 fixedly connected to the upper end of the housing 1, and an electronic component 12 fixedly connected to one end of the display screen 11 inserted into the housing 1. A heat dissipation assembly 2 is provided at the end of the housing 1 away from the display screen 11, and the heat dissipation assembly 2 includes a cooling oil tank 21 provided on the outside of the housing 1. An inlet 22 is fixedly connected to the end of the cooling oil tank 21 away from the housing 1. The heat dissipation assembly 2 can improve the heat dissipation efficiency of the processor and sensors inside the housing 1, thereby reducing the impact of temperature on the processor and sensors, and thus improving the operating response efficiency of the control device.

[0030] like Figure 3As shown, a water pump 23 is fixedly connected to one end of the cooling oil tank 21, and a liquid extraction pipe 24 is fixedly connected to the end of the water pump 23 near the cooling oil tank 21. The end of the liquid extraction pipe 24 away from the water pump 23 is inserted into the cooling oil tank 21, and the end of the water pump 23 away from the liquid extraction pipe 24 is fixedly connected to the outer casing 1. After the water pump 23 is started, it extracts the coolant in the cooling oil tank 21 through the liquid extraction pipe 24.

[0031] like Figure 3 As shown, a cooling oil pipe 25 is fixedly connected to the end of the water pump 23 away from the cooling oil tank 21, and a return oil pipe 26 is fixedly connected to the end of the cooling oil pipe 25 away from the water pump 23. The end of the return oil pipe 26 away from the cooling oil pipe 25 is fixedly connected to the cooling oil tank 21. A heat-conducting plate 27 is fixedly connected to the outside of the end of the cooling oil pipe 25 away from the cooling oil tank 21, and the end of the heat-conducting plate 27 away from the cooling oil pipe 25 is fixedly connected to the electronic component 12. The coolant flows in the cooling oil pipe 25 to absorb and dissipate the heat absorbed by the heat-conducting plate 27.

[0032] like Figure 4 As shown, a motor 28 is installed on the inner side of the end of the outer casing 1 near the cooling oil tank 21, and a first gear 29 is fixedly connected to the output shaft of the motor 28. The end of the first gear 29 away from the motor 28 is rotatably connected to the outer casing 1, and the first gear 29 is driven to rotate by the operation of the motor 28.

[0033] like Figure 1 and Figure 2 As shown, heat dissipation holes 210 are provided at both ends of the outer casing 1, and the two sets of heat dissipation holes 210 are symmetrically arranged.

[0034] like Figure 4 and Figure 5 As shown, a gear is fitted on the outer side of the first toothed column 29 and meshes with a toothed belt 211. The inner side of the toothed belt 211 away from the first toothed column 29 is meshed with a second toothed column 212. The inner side of the second toothed column 212 is rotatably connected to the outer side of the cooling oil pipe 25. The meshing of the toothed belt 211 and the second toothed column 212 drives the rotating drums 213 on both sides to rotate.

[0035] like Figure 5 As shown, a rotating cylinder 213 is fixedly connected to one end of the second toothed column 212, and a fan blade 214 is fixedly connected to the end of the rotating cylinder 213 away from the second toothed column 212. After the rotating cylinder 213 drives the fan blade 214 to rotate, the air on the surface of the cooling oil pipe 25 will flow faster.

[0036] Working principle: During the operation of the control device, after the electronic component 12 operates, it synchronously controls the operation of the water pump 23 and the motor 28. After the water pump 23 starts, it draws out the coolant from the cooling oil tank 21 through the liquid extraction pipe 24. The drawn coolant flows in the cooling oil pipe 25, absorbing the heat generated by the operation of the electronic component 12 on the heat conduction plate 27. After the motor 28 operates, the output shaft drives the first gear 29 to rotate. After the first gear 29 rotates, it meshes with the gear of the toothed belt 211, driving the two sets of toothed belts 211 to rotate. After operation, it drives the second gear 212 and the rotating drum 213 to rotate through the meshing of the gear with the second gear 212. After the rotating drum 213 rotates, it drives the fan blade 214 to rotate synchronously. The rotation of the fan blade 214 accelerates the air flow on the surface of the cooling oil pipe 25, thereby improving the heat dissipation efficiency. When the air flows, it exchanges heat through the heat dissipation holes 210 on both sides. The coolant flowing in the cooling oil pipe 25 absorbs heat and flows into the cooling oil tank 21 through the return oil pipe 26 for circulation. Coolant can be added to the cooling oil tank 21 through the inlet 22 later.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
