Description

Technical Field

[0001] This disclosure relates to the field of vehicle-mounted heating electronic equipment technology, and in particular to a heating source housing device, a vehicle-mounted forward-looking integrated machine, and an automobile. Background Technology

[0002] As automotive front-view all-in-one systems diversify and improve in performance, the heat generated by their internal electronic components is gradually increasing. Currently, heat dissipation vents are typically created in the housing to cool these components. As the temperature inside the housing rises, the air pressure increases, forcing hot air out through the vents, thus cooling the electronic components. However, exhausting hot air through these vents is relatively inefficient for cooling electronic components and cannot meet the significant heat dissipation demands generated by the increased design scale or computing power of automotive front-view all-in-one systems. Utility Model Content

[0003] To address the aforementioned technical problems, this disclosure provides a heat source housing device, an in-vehicle forward-view integrated unit, and an automobile, thereby solving the problem of low heat dissipation efficiency of the in-vehicle forward-view integrated unit and improving its heat dissipation efficiency.

[0004] The first aspect of this disclosure provides a housing device for a heat source, comprising:

[0005] The cover has a receiving space for accommodating a heat source; the first baffle of the cover is provided with an air inlet, the position of which is lower than the installation position of the heat source, so that the air intake from the air inlet passes through the surface of the heat source; the second baffle of the cover is provided with an exhaust port, the position of which is higher than the installation position of the heat source, so that the hot air flowing through the surface of the heat source is discharged from the exhaust port.

[0006] A second aspect of this disclosure provides an in-vehicle forward-looking integrated device, comprising:

[0007] The first aspect of this disclosure provides a housing device for a heat source;

[0008] The heat source is located within the housing space of the heat source's enclosure.

[0009] A third aspect of this disclosure provides a car, comprising:

[0010] windshield;

[0011] The second aspect of this disclosure provides an in-vehicle forward-view integrated device, which is disposed on the windshield.

[0012] The heat source enclosure, vehicle-mounted forward-looking integrated unit, and automobile disclosed herein, by providing a housing space within the enclosure to house the heat source, can effectively protect the heat source when placed within the housing space. An air inlet is located on the first baffle of the enclosure, positioned lower than the installation position of the heat source. This allows cold air entering the housing space from the air inlet to flow over the surface of the heat source, facilitating heat exchange and carrying away the heat emitted by the heat source, thus improving heat dissipation efficiency. An exhaust port is located on the second baffle, positioned higher than the installation position of the heat source. This allows hot air that has come into contact with and been heated by the heat source to flow upwards and quickly exit from the exhaust port, reducing the residence time of hot air within the housing space and further improving heat dissipation efficiency. Additionally... Hot air is exhausted from the exhaust port, which is higher than the installation position of the heat source, reducing the air pressure in the containment space. Cold air is supplied from the air inlet, which is lower than the installation position of the heat source. Since the air inlet is lower than the installation position of the heat source, the cold air must pass over the surface of the heat source before it can be exhausted, which can fully dissipate heat from the surface of the heat source. Since the exhaust port is higher than the installation position of the heat source, the hot air can be quickly exhausted from the exhaust port, so that the air inlet, the installation position of the heat source, and the exhaust port form a directional airflow and a continuous circulating chimney effect. This can improve the heat dissipation effect of the heat source without the need for an external fan, thus improving the heat dissipation efficiency of the vehicle-mounted front-view integrated unit.

[0028] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this disclosure. However, this disclosure may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this disclosure is not limited to the specific embodiments disclosed below.

[0029] In the description of this disclosure, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer" (if any) indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

For those skilled in the art, the specific meaning of the above terms in this disclosure can be understood according to the specific circumstances.

[0031] In this disclosure, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0032] Figure 1 This is a partial view of the windshield and the in-vehicle forward-looking integrated unit in a car, provided in some embodiments of this disclosure.

[0033] Reference Figure 1 As shown, in some examples of this disclosure, a car is provided. (Refer to...) Figure 1 As shown, a car typically includes a windshield 20.

[0034] With the development of automotive intelligence, intelligent driving is generally achieved by installing an in-vehicle forward-facing camera on the windshield. This in-vehicle forward-facing camera is one of the core hardware components of Advanced Driver Assistance Systems (ADAS). Through camera modules, image processing units, and corresponding algorithms, it performs data acquisition, processing, and decision-making functions, and is typically used in driving scenarios such as lane keeping assist, automatic emergency braking, and adaptive cruise control.

[0035] To maintain the aesthetics of the vehicle-mounted front-view integrated unit installed on the windshield 20 of the car, and to facilitate the protection of the integrated unit, the various electronic components inside the integrated unit are usually covered by a cover 100 to improve the aesthetics of the integrated unit.

[0036] In some examples, as in-vehicle front-view integrated cameras diversify and their performance improves, the heat generated by the internal electronic components gradually increases. To dissipate heat from these internal electronic components, heat dissipation holes are typically opened on the housing 100. As the temperature inside the housing 100 rises, the air pressure inside the housing 100 increases, thereby expelling hot air through the heat dissipation holes, which helps to cool the electronic components.

[0037] However, exhausting hot air through the heat dissipation vents is not very efficient at cooling electronic components and cannot meet the heat dissipation requirements generated by the improvement of electronic component performance.

[0038] Figure 2 This is an exploded structural diagram of an in-vehicle front-view integrated machine provided in some embodiments of this disclosure.

[0039] In some examples, refer to Figure 2 As shown, the vehicle-mounted forward-looking integrated unit may include a housing device 10 for a heat source 40. The housing device 10 may be installed on the windshield 20 of the vehicle.

[0040] In some examples, the cover device 10 can be attached to the windshield 20 of a vehicle. For example, it can be attached to the windshield 20 of a vehicle using adhesive.

[0041] In some examples, the enclosure device 10 may include an enclosure 100. The enclosure 100 may have a receiving space 101.

[0042] In some examples, the cover 100 may be made of materials such as plastic, rubber, or engineering plastics. The accommodating space 101 may be integrally formed during the injection molding of the cover 100. The accommodating space 101 may also be obtained by secondary processing of the cover 100 after it has been formed. In this embodiment, the forming method of the accommodating space 101 of the cover 100 is not limited.

[0043] In some examples, the vehicle-mounted forward-looking unit may include a heat source 40. The heat source 40 may be located within the accommodating space 101.

[0044] In some examples, the heat source 40 may include the camera module, graphics processing unit (GPU), central processing unit (CPU), etc., as described in detail in the foregoing embodiments of this disclosure. It is understood that the specific types of heat source 40 in the embodiments of this disclosure are merely illustrative examples and are not intended to limit the specific type of heat source 40. When the in-vehicle front-view integrated machine integrates other electronic components (such as a neural network processor), the heat source 40 may include other types of electronic components. These will not be listed individually in the embodiments of this disclosure.

[0045] In some examples, refer to Figure 2 As shown, the first baffle 110 of the cover 100 may be provided with an air inlet 111. The air inlet 111 may extend through the inner and outer sides of the first baffle 110. That is to say, air can enter the accommodating space 101 from the air inlet 111.

[0046] Figure 3This is a cross-sectional view of an in-vehicle front-view integrated unit provided in some embodiments of this disclosure.

[0047] In some examples, refer to Figure 3 As shown, the position of the air inlet 111 can be lower than the installation position of the heat source 40.

[0048] In some examples, refer to Figure 3 As shown, after the heat source 40 is installed in the receiving space 101, the air inlet 111 can be positioned opposite to the heat source 40. That is, the cold air entering the receiving space 101 from the air inlet 111 can flow over the surface of the heat source 40, thereby facilitating the timely removal of heat from the surface of the heat source 40.

[0049] In some examples, refer to Figure 2 and Figure 3 As shown, the second baffle 120 of the cover 100 may be provided with an exhaust port 121.

[0050] In some examples, refer to Figure 3 As shown, the exhaust port 121 can be positioned higher than the installation position of the heat source 40. In this way, the hot air flowing over the surface of the heat source 40 can be discharged from the exhaust port 121 in a timely manner.

[0051] In some examples, refer to Figure 3 As shown, the airflow can follow Figure 3 The air enters the accommodating space 101 from the air inlet 111 provided on the first baffle 110 in the direction indicated by the middle arrow a.

[0052] In some examples, refer to Figure 2 and Figure 3 As shown, the first baffle 110 and the second baffle 120 can be two baffles opposite to each other on the cover 100.

[0053] In some examples, refer to Figure 1 As shown, since the windshield 20 of the car is tilted, after the cover 100 is installed on the windshield 20, the position of the first baffle 110 can be lower than the position of the second baffle 120. Therefore, in some examples, the first baffle 110 can be called the lower baffle (in some examples, it can also be called the bottom plate), and the second baffle 120 can be called the upper baffle (in some examples, it can also be called the top plate).

[0054] The housing device 10 for the heat source 40 provided in this disclosure, by providing a receiving space 101 in the housing 100 to accommodate the heat source 40, can protect the heat source 40 by placing it within the receiving space 101. An air inlet 111 is provided on the first baffle 110 of the housing 100, and the position of the air inlet 111 is lower than the installation position of the heat source 40. Thus, the cold air entering the receiving space 101 from the air inlet 111 can flow over the surface of the heat source 40, fully exchanging heat with the surface of the heat source 40 and carrying away the heat emitted by the heat source 40, thereby improving the heat dissipation efficiency of the heat source 40. An exhaust port 121 is provided on the second baffle 120, and the position of the exhaust port 121 is higher than the installation position of the heat source 40. Thus, the hot air that has come into contact with and been heated by the heat source 40 flows upward and can be quickly discharged from the exhaust port 121, which is higher than the installation position of the heat source 40, reducing the residence time of the hot air in the receiving space 101 and improving the heat dissipation of the heat source 40. Efficiency; In addition, hot air is discharged from the exhaust port 121, which is higher than the installation position of the heat source 40, and the air pressure in the accommodating space 101 is reduced. Cold air is supplied from the air inlet 111, which is lower than the installation position of the heat source 40. Since the air inlet 111 is lower than the installation position of the heat source 40, the cold air must pass over the surface of the heat source 40 before it can be discharged, which can fully dissipate heat from the surface of the heat source 40. Since the exhaust port 121 is higher than the installation position of the heat source 40, hot air can be quickly discharged from the exhaust port 121, so that the air inlet 111, the installation position of the heat source 40 and the exhaust port 121 form a directional airflow and a continuous circulating chimney effect, which can improve the heat dissipation effect of the heat source 40 without the need for an external fan, thereby improving the heat dissipation efficiency of the vehicle front-view integrated machine.

[0055] Additionally, refer to Figure 1 As shown, the housing device 10 of the heat source 40 provided in some embodiments of this disclosure has an air inlet 111 provided on the first baffle 110 at a position lower than the installation position of the heat source 40, and an exhaust outlet 121 provided on the second baffle 120 at a position higher than the heat source 40. Thus, within the vehicle space, air flows along... Figure 1 The air flows in the direction indicated by the middle arrow b, that is, it enters the accommodating space 101 from the lower air intake 111 and is discharged from the higher exhaust port 121. The upward flow of hot air can prevent hot air from blowing onto the occupants of the vehicle and improve the physical comfort of the occupants.

[0056] In some examples, refer to Figure 2 and Figure 3 As shown, the housing device 10 may include a cooling fan 200.

[0057] In some examples, the cooling fan 200 can be housed within the accommodating space 101. In this way, the cooling fan 200 can be shielded by the cover 100, which on the one hand can protect the cooling fan 200, and on the other hand, placing the cooling fan 200 inside the cover 100 can improve the aesthetics and neatness of the cover 100.

[0058] In some examples, refer to Figure 3 As shown, the cooling fan 200 can be installed on the second baffle 120.

[0059] In some examples, the cooling fan 200 can be connected to the second baffle 120 by means of connecting components such as bolts, screws or threaded rods.

[0060] In some examples, the cooling fan 200 can be snapped onto the second baffle 120.

[0061] In some examples, the cooling fan 200 can be glued to the second baffle 120.

[0062] In some examples, the cooling fan 200 may include an axial fan. The cooling fan 200 may be located at the exhaust port 121. That is, the cooling fan 200 can draw in hot air from the containment space 101 and exhaust it from the exhaust port 121. In this way, the exhaust of hot air from the containment space 101 can be accelerated, which is beneficial for dissipating heat from the heat source 40 and improving the heat dissipation efficiency of the heat source 40.

[0063] In some examples of embodiments of this disclosure, the specific size and type of the fan can be selected based on the specific heat output of the heat source 40. For example, when the heat output of the vehicle-mounted front-view all-in-one machine is relatively small, a cooling fan 200 with smaller power and size can be selected for active cooling; when the heat output of the vehicle-mounted front-view all-in-one machine is relatively large, a cooling fan 200 with larger power and size can be selected for active cooling.

[0064] In some examples of embodiments of this disclosure, by providing a cooling fan 200 within the accommodating space 101 and placing the cooling fan 200 on the second baffle 120, a directional airflow channel can be formed from the inner surface of the second baffle 120 outwards. When the cooling fan 200 operates, the negative pressure zone generated can draw out the high-temperature gas between the second baffle 120 and the heat source 40 and discharge it through the exhaust port 121, thereby forming a forced convection path through the cooling fan 200 and improving the heat dissipation efficiency of the heat source 40.

[0065] Additionally, refer to Figure 1As shown in this embodiment, after the vehicle-mounted forward-looking integrated unit is installed on the windshield 20 of the car, the position of the second baffle 120 is higher than the position of the first baffle 110, and the exhaust port 121 is higher than the air inlet 111; when the cooling fan 200 is running, the cooling fan 200 drives the airflow along... Figure 1 The air flows in the direction indicated by the middle arrow b, meaning that the hot air discharged from the exhaust port 121 flows upward, which can avoid blowing directly onto the occupants 30 and improve the riding experience of the occupants 30.

[0066] In some examples, refer to Figure 3 As shown, the cooling fan 200 can be positioned above the surface of the heat source 40 to facilitate effective heat exchange with the airflow.

[0067] In some examples, refer to Figure 3 As shown, the bottom of the heat source 40 may be provided with heat dissipation fins 410. Airflow entering the receiving space 101 from the air inlet 111 can flow over the heat dissipation fins 410, thereby carrying away heat from the heat source 40. In other words, the effective area for heat exchange between the airflow and the surface of the heat source 40 can be the area where the heat dissipation fins 410 are provided. It is understood that in some examples of embodiments of this disclosure, the area where the heat dissipation fins 410 are located is only shown as a specific example of an effective area for heat exchange between the airflow and the surface of the heat source 40; the airflow can also exchange heat with other surfaces of the heat source 40. That is, any surface of the heat source 40 through which the airflow flows can be considered an effective area for heat exchange.

[0068] In some examples, after the vehicle-mounted front-view unit is installed on the windshield 20 of the car, the cooling fan 200 may be positioned above the surface of the heat source 40, in an area where heat exchange with the airflow is effective.

[0069] In some examples of embodiments of this disclosure, the cooling fan 200 is positioned above the surface of the heat source 40 in an effective area for heat exchange with the airflow. Thus, after the airflow exchanges heat with the surface of the heat source 40, the hot air flows upwards and can be promptly drawn away by the cooling fan 200, allowing the hot air within the accommodating space 101 to be discharged in a timely manner, thereby improving the heat dissipation efficiency of the heat source 40.

[0070] In some examples, the heat source 40 may have a temperature detection sensor.

[0071] In some examples, the temperature sensing sensor may include any one of a thermocouple, a resistance temperature detector (RTD), a thermistor, an infrared thermopile, a fiber Bragg grating, or a quantum thermometer.

[0072] In some examples, temperature sensors can detect the temperature of high-power devices within the containment space 101. For instance, a temperature sensor can monitor the temperature of a heat source 40 within the containment space.

[0073] In some examples, the temperature signal detected by the temperature sensor can be fed back to the cooling fan 200. The cooling fan 200 can then start and stop based on the temperature detected by the temperature sensor.

[0074] In some examples, the cooling fan 200 can be activated when the temperature sensor detects that the temperature inside the containment space 101 exceeds a preset temperature threshold, so as to actively dissipate heat from the heat source 40.

[0075] In some examples, during the operation of the in-vehicle forward-looking integrated unit, when the operating power is low (e.g., when the car is just starting or has stopped), the heat source 40 emits less heat, and the temperature inside the housing 101 is relatively low. At this time, the heat emitted by the heat source 40 heats the air inside the housing 101. (Refer to...) Figure 3 As shown, hot air along Figure 3 The air flows in the direction indicated by the middle arrow c and is discharged from the containing space 101. The still air in the containing space 101 becomes flowing air, creating a negative pressure inside the containing space 101. This negative pressure draws the outside cold air along... Figure 3 The air is drawn into the receiving space 101 in the direction indicated by the middle arrow a, thereby creating a chimney-effect airflow structure between the air inlet 111 of the first baffle 110, the receiving space 101, and the exhaust outlet 121 of the second baffle 120. This chimney effect enables active heat dissipation of the heat source 40. In this case, the cooling fan 200 does not need to be started, saving the energy consumed by the cooling fan 200.

[0076] In some examples, during the operation of the vehicle-mounted front-view integrated unit, when the operating power is high, the heat source 40 emits a large amount of heat. After the heat source 40 is cooled by the chimney effect, when the temperature inside the housing 101 exceeds the preset temperature threshold, the cooling fan 200 is activated to draw in the hot air inside the housing 101, which can accelerate the discharge of hot air from the housing 101 and thus improve the heat dissipation efficiency of the heat source 40.

[0077] In addition, during vehicle use, when the temperature inside the containment space 101 is greater than the preset temperature threshold, the cold air cooled by the vehicle's air conditioning compressor can enter the containment space 101 from the air intake 111 along the windshield 20. This allows the cold air cooled by the vehicle's air conditioning compressor to dissipate heat from the heat source and cool it down, thereby improving the heat dissipation efficiency of the heat source 40.

[0078] In some examples of embodiments of this disclosure, the temperature inside the accommodating space 101 is detected by a temperature sensor of the heat source 40, and the cooling fan 200 starts and stops according to the temperature detected by the temperature sensor. In this way, the chimney effect of the low air inlet 111 and high exhaust outlet 121 can be fully utilized to dissipate heat from the heat source 40. When the temperature is high, the cooling fan 200 actively dissipates heat, which can reduce the energy consumption of the cooling fan 200 and effectively dissipate heat from the heat source 40, thereby improving the heat dissipation efficiency of the heat source 40.

[0079] Figure 4 This is a schematic diagram of the overall structure of an in-vehicle front-view integrated unit provided in some embodiments of this disclosure. Figure 5 yes Figure 4 The main view.

[0080] In some examples, refer to Figure 4 and Figure 5 As shown, the air inlet 111 includes multiple sub-air inlets 1111, which are located along the length of the first baffle 110. Figure 4 (as shown by the x-axis) extends, and multiple sub-intake ports 1111 extend along the width direction of the first baffle 110 ( Figure 4 Arranged in the direction shown by the z-axis.

[0081] In some examples, refer to Figure 4 and Figure 5 As shown, the sub-inlet 1111 can be a strip-shaped hole, the length direction of which is consistent with the length direction of the first baffle 110, and the width direction of which is consistent with the width direction of the first baffle 110.

[0082] In some examples, the length of the sub-inlet 1111 can be the same as the length of the first baffle 110. That is, the length of the sub-inlet 1111 can extend to the entire length of the first baffle 110.

[0083] In some examples, the sub-inlet 1111 can be an elliptical hole. The major axis of the elliptical hole can extend along the length of the first baffle 110, and the minor axis of the elliptical hole can extend along the width of the first baffle 110.

[0084] In some examples, the sub-inlet 1111 can be a diamond-shaped hole.

[0085] It is understood that the specific shape of the sub-inlet 1111 in this embodiment is only shown as a specific example and is not intended to limit the specific shape of the sub-inlet 1111. In other examples, the sub-inlet 1111 may also have other shapes.

[0086] In some examples of embodiments of this disclosure, multiple sub-intake ports 1111 are provided on the first baffle 110, and the multiple sub-intake ports 1111 are constructed to form an air intake port 111. In this way, the opening ratio of the first baffle 110 can be increased, thereby increasing the air intake volume of the air intake port 111 and improving the heat dissipation efficiency of the heat source 40.

[0087] In some examples, refer to Figure 3 As shown, the opening direction of the sub-inlet 1111 is relative to the first direction (e.g., Figure 3 The direction indicated by the middle arrow d) is tilted at a first preset angle α. The first direction can be a direction perpendicular to the surface of the first baffle 110 (e.g., Figure 3 (The direction indicated by the middle arrow d).

[0088] In some examples, refer to Figure 3 As shown, the end of the sub-intake 1111 facing the accommodating space 101 is higher than the end of the sub-intake 1111 that is farther away from the accommodating space 101. That is, the end of the sub-intake 1111 facing the external environment (the interior environment of the car) is lower than the end of the sub-intake 1111 facing the accommodating space 101. The sub-intake 1111 is tilted upward along the direction of airflow.

[0089] In some examples, the first preset angle α can be set according to specific needs. For example, the first preset angle can be set according to the tilt angle of the windshield 20 of the car. In some examples of embodiments of this disclosure, the opening direction of the sub-intake port 1111 is tilted, so that the light diffused by the heat source 40 in the accommodating space 101 propagates in a straight line and the light cannot propagate from the air intake port 111 to the outside of the cover 100. That is to say, the heat source 40 in the accommodating space 101 cannot be observed from outside the cover 100, which can improve the overall aesthetics of the vehicle front-view integrated machine.

[0090] In some examples, the first preset angle α can be set based on whether the heat source 40 inside the cover 100 can be observed through the windshield 20 of the car from outside the car.

[0091] In some examples, the first preset angle α can be set to 45°-75°.

[0092] In some examples, the first preset angle α can be set to 45°-60°.

[0093] In some examples, the first preset angle α can be set to 60°-75°.

[0094] In some examples of embodiments of this disclosure, by tilting the opening direction of the sub-inlet 1111, thus, referring to Figure 3As shown, the airflow entering through the air inlet 111 can be concentrated on the end face of the heat source 40 facing the air inlet 111, and gradually flow over the bottom of the heat source 40, so that the airflow can fully contact the heat source 40 and improve the heat dissipation efficiency of the heat source 40.

[0095] Figure 6 This is another overall structural schematic diagram of an in-vehicle front-view integrated machine provided in some embodiments of this disclosure. Figure 7 yes Figure 6 The main view.

[0096] In some examples, refer to Figure 6 and Figure 7 As shown, the exhaust port 121 includes a plurality of sub-exhaust ports 1211, which are located along the length direction of the second baffle 120 (e.g., Figure 6 The direction output by the x-axis extends, and multiple sub-exhaust ports 1211 extend along the width direction of the second baffle 120 (e.g., the direction output by the x-axis). Figure 6 Arranged in the direction shown by the z-axis.

[0097] In some examples, the shape of the sub-exhaust port 1211 may be the same as, similar to or similar to the shape of the sub-inlet port 1111. For details, please refer to the detailed description of the shape of the sub-inlet port 1111 in the foregoing embodiments of this disclosure. This disclosure will not repeat the details in this embodiment.

[0098] In some examples of embodiments of this disclosure, by providing a plurality of sub-exhaust ports 1211, which extend along the length direction of the second baffle 120 and are arranged along the width direction of the second baffle 120, the opening ratio of the second baffle 120 can be increased, the exhaust speed of hot air in the accommodating space 101 can be increased, and the heat dissipation efficiency of the heat source 40 can be improved.

[0099] In some examples, refer to Figure 3 As shown, the opening direction of the sub-exhaust port 1211 is relative to the second direction (e.g., Figure 3 (In the direction indicated by the middle arrow e) tilted at a second preset angle β, the end of the sub-exhaust port 1211 facing the receiving space 101 is lower than the end of the sub-exhaust port 1211 away from the receiving space 101.

[0100] In some examples, the second direction can be a direction perpendicular to the surface of the second baffle 120, for example... Figure 3 The direction indicated by the middle arrow e.

[0101] In some examples, the second preset angle β can be adjusted according to specific needs. For example, the second preset angle β can be set according to the tilt angle of the windshield 20 of the car. In some examples of embodiments of this disclosure, the opening direction of the sub-exhaust port 1211 is tilted so that the diffuse reflected light emitted by the heat source 40 in the accommodating space 101 propagates in a straight line, and the light cannot propagate from the exhaust port 121 to the outside of the cover 100. Therefore, the heat source 40 in the accommodating space 101 cannot be seen from the outside of the cover 100, thereby improving the overall aesthetics of the vehicle-mounted front-view integrated machine.

[0102] In some examples, the specific value of the second preset angle β can be set based on whether the heat source 40 inside the cover 100 can be observed through the exhaust port 121 in the vehicle interior environment.

[0103] In some examples, the second preset angle β can be set to 45°-75°.

[0104] In some examples, the second preset angle β can be set to 45°-60°.

[0105] In some examples, the second preset angle β can be set to 60°-75°.

[0106] In some examples of embodiments of this disclosure, the opening direction of the sub-exhaust port 1211 is tilted relative to the second direction by a second preset angle β. Thus, inside the vehicle, occupants cannot observe the heat source 40 within the accommodating space 101 through the exhaust port 121, improving the aesthetics of the in-vehicle front-view integrated unit.

[0107] In addition, the end of the sub-exhaust port 1211 facing the receiving space 101 is set lower than the end of the sub-exhaust port 1211 that is far away from the receiving space 101. In this way, the exhaust direction of the exhaust port 121 is upward, which is consistent with the direction of movement of hot air, making it easier for hot air to be discharged from the exhaust port 121 and improving the heat dissipation efficiency of the heat source 40.

[0108] In some examples, refer to Figure 4 and Figure 6 As shown, the length of the exhaust port 121 is less than the length of the air inlet 111.

[0109] In some examples, the extension length of the sub-exhaust port 1211 along the length direction of the second baffle 120 is less than the extension length of the sub-intake port 1111 along the length direction of the first baffle 110. The length direction of the second baffle 120 and the length direction of the first baffle 110 may be the same.

[0110] In some examples of embodiments of this disclosure, by setting the length of the exhaust port 121 to be less than the length of the air inlet 111, the cold air entering the accommodating space 101 from the air inlet 111 can fully contact and exchange heat with the surface of the heat source 40, thereby prolonging the heat exchange time between the cold air and the heat source 40, improving the effective utilization rate of the cold air, and reducing the energy consumption for heat dissipation from the heat source 40.

[0111] In some examples, refer to Figure 4 and Figure 6 As shown, the housing 10 of the vehicle-mounted forward-looking integrated unit may include a housing 130. (Refer to...) Figure 3 As shown, the outer casing 130 can be connected between the first baffle 110 and the second baffle 120.

[0112] In some examples, the housing 130 can be fixedly connected to the first baffle 110 and the second baffle 120 by screws.

[0113] In some examples, the housing 130 can be snapped together with the first baffle 110 and the second baffle 120.

[0114] In some examples, the housing 130 can be bonded to the first baffle 110 and the second baffle 120.

[0115] In some examples, the outer shell 130, the first baffle 110, and the second baffle 120 can be integral parts. For example, the outer shell 130, the first baffle 110, and the second baffle 120 can be integrally formed during the injection molding of the cover 100.

[0116] In some examples, the housing 130, the first baffle 110, and the second baffle 120 can be formed into a single piece by secondary injection molding or two-color injection molding.

[0117] In some examples, refer to Figure 3 As shown, the bottom plate of the outer casing 130 is provided with several heat dissipation holes 131. The heat dissipation holes 131 can be through holes. The heat dissipation holes 131 extend into the receiving space 101, thereby connecting the receiving space 101 with the external environment.

[0118] In some examples, the diameter of the heat dissipation hole 131 may be smaller than the diameter of either the air inlet 111 or the exhaust port 121.

[0119] In some examples of embodiments of this disclosure, heat dissipation holes 131 are provided on the bottom plate of the housing 130 connected between the first baffle 110 and the second baffle 120. This increases the air intake area through the heat dissipation holes 131, thereby enhancing the convective heat transfer effect and improving the heat dissipation efficiency of the heat source 40.

[0120] In addition, by setting the diameter of the heat dissipation hole 131 to be smaller than the diameter of either the air inlet 111 or the exhaust port 121, the heat source 40 inside the housing space 101 can not be observed from the outside, thus improving the overall aesthetics of the vehicle-mounted front-view integrated unit.

[0121] In some examples, refer to Figure 2 and Figure 3 As shown, the cover assembly 10 may include a mounting bracket 300. The mounting bracket 300 can be mounted on the windshield 20 of a vehicle.

[0122] In some examples, the mounting bracket 300 can be attached to the windshield 20 of a car.

[0123] In some examples, the cover 100 can be connected to the mounting bracket 300 to form a receiving space 101.

[0124] In some examples, the cover 100 can be connected to the mounting bracket 300 by connecting components such as screws, bolts or threaded rods.

[0125] In some examples, the cover 100 can snap onto the mounting bracket 300.

[0126] In some examples, the cover 100 may be bonded to the mounting bracket 300.

[0127] In some examples, refer to Figure 2 and Figure 3 As shown, the mounting bracket 300 may have a mounting position 310. The heat source 40 may be installed in the mounting position 310. The mounting position 310 is the installation location of the heat source 40.

[0128] In some examples, the heat source 40 can be mounted to the mounting position 310 via connecting components such as bolts, screws or threaded rods.

[0129] In some examples, the heat source 40 can be snapped into the mounting position 310.

[0130] In some examples, the heat source 40 can be attached to the mounting position 310.

[0131] In some examples of embodiments of this disclosure, a mounting bracket 300 is provided, and a heat source 40 is mounted on a mounting position 310 of the mounting bracket 300. The cover 100 is connected to the mounting bracket 300, thereby enclosing the heat source 40 within the receiving space 101. This facilitates the fixing of the vehicle-mounted front-view integrated unit to the windshield 20 of the vehicle.
