Description

Technical Field

[0001] This utility model relates to the field of automotive dashboard technology, specifically to a cooling structure for automotive dashboards. Background Technology

[0002] As the core hub for driver-vehicle interaction, the car dashboard has been upgraded from a low-power structure of traditional mechanical pointers and simple indicator lights to a high-power complex system that integrates multiple screens (LCD instrument panel, central control screen, AR-HUD) and intelligent interaction.

[0003] In existing technologies, the instrument panel cooling structure uses thermally conductive silicone to bond with the heating element. The heat is conducted to the external environment through the shell and then diffused through natural air convection. Ventilation holes are opened at the top and bottom of the instrument panel shell to create natural airflow by utilizing the temperature difference of the air inside the vehicle, which helps to remove internal heat. The ventilation holes are often equipped with dust filters to prevent dust from entering.

[0004] The instrument panel dust filter is mostly integrated inside the center console and is fixed to the instrument panel housing by screws or clips. Due to the lack of a quick-release structure, tools are needed to disassemble the instrument panel when cleaning the dust filter, which can lead to the dust filter becoming clogged due to lack of cleaning over a long period of time, thus affecting the heat dissipation effect inside the instrument panel. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a cooling structure for automotive dashboards. The dashboard is removed from the center console by pressing the buckle, and then the first spring is compressed by pulling the slider at the bottom of the dashboard, causing the locking pin to disengage from the locking hole of the dust filter. This allows the dust filter to be easily pulled out for cleaning or replacement. After cleaning, it is reset and fixed by the locking pin, thus avoiding the problem of the dust filter clogging and affecting the internal heat dissipation effect.

[0006] The objective of this utility model is achieved through the following technical solution: The cooling structure for an automotive dashboard includes a dashboard body; it also includes an air intake slot extending through the lower end of the dashboard body and a sealing component located on the outer side of the dashboard body; a dustproof mesh is slidably installed on the inner wall of the air intake slot, and locking holes are provided on both sides of the dustproof mesh; two first slots are symmetrically provided at the lower end of the dashboard body, and a slider is slidably installed on the inner wall of the first slot; a first spring is fixedly connected between the slider and the first slot; a locking pin is fixedly connected to the other end of the slider, and the locking pin is adapted to the locking hole.

[0007] In one optional embodiment, a display module is provided inside the instrument panel body, a heat conduction plate is provided at the rear end of the display module, and multiple fixing bolts are threaded at the four corner edges of the heat conduction plate.

[0008] In one optional embodiment, a limiting spring is sleeved on the outer wall of the fixing bolt, the limiting spring is located at the rear end of the heat-conducting plate, and thermal grease is provided between the heat-conducting plate and the display module.

[0009] In one optional embodiment, a plurality of heat-conducting copper pipes are fixedly connected to the outer side of the heat-conducting plate, and a plurality of heat-dissipating fins are fixedly connected to the outer wall of the heat-conducting copper pipes. The plurality of heat-dissipating fins are distributed at equal intervals, and a cooling fan is fixedly connected to one end of the heat-dissipating fins near the air inlet slot.

[0010] In one optional embodiment, an air outlet slot is provided through the upper end of the instrument panel body, and a channel composed of multiple heat dissipation fins is interconnected with the air inlet slot and the air outlet slot.

[0011] In one optional embodiment, the sealing assembly includes a fixing plate fixed to the side of the instrument panel body, an air inlet through the surface of the fixing plate, and a sealing plate slidably disposed on the surface of the fixing plate.

[0012] In one alternative embodiment, multiple sealing plates are jointly fixed to a connecting rod, one end of which extends outward and is fixed to a limiting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After prolonged use, a layer of dust will accumulate on the dust filter. To remove the instrument panel from the center console, press the buckle to remove it. Then, pull the slider at the bottom of the instrument panel to compress the first spring, causing the locking pin to disengage from the locking hole of the dust filter. This allows the dust filter to be easily pulled out for cleaning or replacement. After cleaning, reset the filter and secure it with the locking pin to prevent the dust filter from becoming clogged and affecting the internal heat dissipation.

[0014] By pulling the connecting rod of the sealing assembly, multiple sealing plates slide synchronously, exposing the air inlet on the fixed plate. Since the air inlet is connected to the air outlet of the air conditioner, the opening and closing of the air inlet is controlled by the scale lines on the outer wall of the connecting rod according to the feedback of the temperature sensor inside the instrument panel, so as to introduce cold air blown out by the air conditioner and further reduce the temperature inside the instrument panel. When the heat generation is small, the connecting rod is pushed in the opposite direction to close the air inlet, thereby preventing external dust from entering the interior.

[0021] Please refer to Figures 1-5 This utility model provides an embodiment of a cooling structure for an automotive dashboard, comprising a dashboard body 1; an air inlet slot 101 extending through the lower end of the dashboard body 1 and a sealing assembly disposed on the outer side of the dashboard body 1; a dustproof mesh 102 is slidably disposed on the inner wall of the air inlet slot 101, and locking holes 103 are provided on both sides of the dustproof mesh 102; two first slots 104 are symmetrically disposed at the lower end of the dashboard body 1, and sliders 105 are slidably disposed on the inner wall of the first slots 104; a first spring 106 is fixedly connected between the slider 105 and the first slot 104; and a locking pin 107 is fixedly connected to the other end of the slider 105. The locking pin 107 is adapted to the locking hole 103. The instrument panel is removed from the center console by pressing the buckle. Then, by pulling the slider 105 at the bottom of the instrument panel, the first spring 106 is compressed, so that the locking pin 107 is disengaged from the locking hole 103 of the dust filter 102. The dust filter 102 can be easily pulled out for cleaning or replacement. After cleaning, it is reset and fixed by the locking pin 107. This solves the problem that due to the lack of a quick-release structure, the instrument panel needs to be disassembled with tools when cleaning the dust filter 102, which leads to the dust filter 102 being blocked due to lack of cleaning for a long time, thus affecting the heat dissipation effect inside the instrument panel.

[0022] Please refer to Figures 1-4In a preferred embodiment of this utility model, a display module 2 is provided inside the instrument panel body 1. A heat-conducting plate 3 is provided at the rear end of the display module 2. Multiple fixing bolts 4 are threaded at the four corner edges of the heat-conducting plate 3. Limiting springs 5 ​​are sleeved on the outer wall of the fixing bolts 4. The limiting springs 5 ​​are located at the rear end of the heat-conducting plate 3. Thermal grease 6 is provided between the heat-conducting plate 3 and the display module 2. Multiple heat-conducting copper pipes 7 are fixedly connected to the outer side of the heat-conducting plate 3. Multiple heat-dissipating fins 8 are fixedly connected to the outer wall of the heat-conducting copper pipes 7. The multiple heat-dissipating fins 8 are equidistantly distributed. A cooling fan 9 is fixedly connected to the end of the heat-dissipating fins 8 near the air inlet slot 101. An air outlet 10 is provided at the upper end. A channel composed of multiple heat dissipation fins 8 is interconnected with the air inlet 101 and the air outlet 10. The heat absorbed by the heat conduction plate 3 is quickly conducted to the heat dissipation fins 8 through the heat conduction copper pipe 7. The cooling fan 9 starts and draws in external cold air from the air inlet 101 at the lower end of the instrument panel body 1. The air is filtered by the dust filter 102 to remove dust. When the cold air flows through the channel between the heat dissipation fins 8, it exchanges heat with the fins, absorbs heat and becomes hot air, and finally is discharged from the air outlet 10 at the upper end, forming a continuous heat dissipation airflow circulation, improving air circulation efficiency and enhancing the overall heat dissipation effect.

[0023] Please refer to Figure 5 In a preferred embodiment of this utility model, the sealing assembly includes a fixed plate 201 fixed to the side of the instrument panel body 1, an air inlet 202 penetrating through the surface of the fixed plate 201, and a sealing plate 203 slidably disposed on the surface of the fixed plate 201. Multiple sealing plates 203 are jointly fixed to a connecting rod 204. One end of the connecting rod 204 extends outward and is fixed to a limit block 205. When the display module 2 generates a large amount of heat, the connecting rod 204 of the sealing assembly can be pulled to cause multiple sealing plates 203 to slide synchronously, exposing the air inlet 202 on the fixed plate 201. Since the air inlet 202 is interconnected with the air outlet of the air conditioner, the opening and closing size of the air inlet 202 is controlled by the scale lines on the outer wall of the connecting rod 204 based on feedback from the temperature sensor inside the instrument panel, introducing cold air blown out by the air conditioner to further reduce the temperature inside the instrument panel. When the heat generation is low, the connecting rod 204 is pushed in the opposite direction to close the air inlet 202, thereby preventing external dust from entering the interior.

[0024] During use, the heat generated by the display module 2 is first transferred to the tightly fitted heat-conducting plate 3 through the thermal grease 6 at the rear end. The thermal grease 6 fills the gaps to ensure the highest heat conduction efficiency. By rotating the fixing bolt 4 in conjunction with the limiting spring 5, the heat-conducting plate 3 is kept in close contact with the display module 2 to prevent vibration from causing gaps between the heat-conducting plate 3 and the heat source, thus interrupting heat conduction.

[0025] The heat absorbed by the heat-conducting plate 3 is quickly conducted to the heat dissipation fins 8 through the heat-conducting copper pipe 7. The cooling fan 9 starts and draws in external cold air from the air intake slot 101 at the lower end of the instrument panel body 1. The air is filtered by the dust filter 102 to remove dust. When the cold air flows through the channel between the heat dissipation fins 8, it exchanges heat with the fins, absorbs heat and becomes hot air, and finally is discharged from the air outlet slot 10 at the upper end, forming a continuous heat dissipation airflow circulation, improving air circulation efficiency and enhancing the overall heat dissipation effect.

[0026] When the display module 2 generates a large amount of heat, the connecting rod 204 of the sealing assembly can be pulled to drive multiple sealing plates 203 to slide synchronously, exposing the air inlet 202 on the fixed plate 201. Since the air inlet 202 is connected to the air outlet of the air conditioner, the opening and closing size of the air inlet 202 is controlled by the scale lines on the outer wall of the connecting rod 204 according to the feedback of the temperature sensor inside the instrument panel, so as to introduce cold air blown out by the air conditioner and further reduce the temperature inside the instrument panel. When the heat generation is small, the connecting rod 204 is pushed in the opposite direction to close the air inlet 202, thereby preventing external dust from entering the interior.

[0027] After prolonged use, a layer of dust will accumulate on the dust filter 102. The instrument panel can be removed from the center console by pressing the buckle. Then, by pulling the slider 105 at the bottom of the instrument panel, the first spring 106 is compressed, causing the locking pin 107 to disengage from the locking hole 103 of the dust filter 102. This allows the dust filter 102 to be easily pulled out for cleaning or replacement. After cleaning, it is reset and fixed by the locking pin 107, thus preventing the dust filter 102 from becoming clogged and affecting the internal heat dissipation.

[0028] By following the steps described above, the instrument panel can be removed from the center console by pressing the buckle. Then, by pulling the slider 105 at the bottom of the instrument panel, the first spring 106 is compressed, causing the locking pin 107 to disengage from the locking hole 103 of the dust filter 102. This allows the dust filter 102 to be easily pulled out for cleaning or replacement. After cleaning, it is reset and fixed by the locking pin 107. This solves the problem that due to the lack of a quick-release structure, tools are needed to disassemble the instrument panel when cleaning the dust filter 102, which leads to the dust filter 102 becoming clogged due to lack of cleaning over a long period of time, thus affecting the heat dissipation effect inside the instrument panel.
