Description

Technical Field

[0001] This application belongs to the technical field of vehicle controllers, and particularly relates to an in-vehicle controller assembly with a heat dissipation structure. Background Art

[0002] The in-vehicle controller assembly is one of the important components of an automobile, which is used to control and calculate the electronic devices of the automobile, and is also known as a vehicle control unit, etc.

[0003] In the related art, such as the Chinese invention patent with the publication number CN117279251A, an in-vehicle controller assembly is disclosed, which includes a processor, a shielding protective case, and a mounting main board. The processor has a chip, the shielding protective case is wrapped around the outside of the processor, a mounting position is provided in the board body of the mounting main board, and the processor is detachably mounted on the mounting position through an insertion and fixing mechanism in the shielding protective case. A heat dissipation structure is provided at the part of the mounting main board corresponding to the shielding protective case. The heat dissipation structure is a heat dissipation cavity provided in the mounting main board, and the mounting main board has an inlet and outlet liquid pipe opening communicated with the heat dissipation cavity. That is to say, it realizes the heat dissipation of the in-vehicle controller assembly by using a cooling medium to enter and exit the heat dissipation cavity through the inlet and outlet liquid pipe openings. However, the cooling medium needs a supporting circulation system to enter or exit the heat dissipation cavity. If it relies on the existing circulation system of the vehicle, it will affect the heat dissipation of other components of the vehicle. If a new circulation system is added, it will increase the manufacturing cost of the vehicle. Therefore, how to reduce the manufacturing cost of the vehicle on the premise of ensuring the original heat dissipation effect of other components of the vehicle has become an urgent problem to be solved. Utility Model Content

[0004] This application provides an in-vehicle controller assembly with a heat dissipation mechanism to realize the heat dissipation of the in-vehicle controller assembly and reduce the manufacturing cost of the vehicle.

[0005] The technical solution adopted in this application is as follows:

[0006] An in-vehicle controller assembly with a heat dissipation mechanism includes a controller main body and an air supply channel. The controller main body has a connection end provided with a connector socket and an avoidance end opposite to the connection end. The air supply channel has an air inlet and an air outlet. The air outlet is arranged opposite to the avoidance end, and the air inlet is located at the front or bottom of the vehicle, so that the air flow can enter the air supply channel through the air inlet during the vehicle's forward movement and blow towards the controller main body through the air outlet.

[0007] By adopting the above technical solution, when the vehicle equipped with the vehicle-mounted controller assembly of the present application is running, the air flow enters the air supply channel through the air inlet and blows towards the controller assembly body through the air outlet, thereby realizing the heat dissipation of the controller assembly. Moreover, the present application utilizes the air flow during the forward movement of the vehicle to dissipate heat from the controller assembly body, avoiding the need to set up a coolant circulation system, and thus reducing the manufacturing cost of the vehicle.

[0008] Optionally, connecting arms are downwardly extended and provided on both opposite sides of the controller assembly body, and one end of the connecting arm far from the controller assembly body is used for connecting to the vehicle body, so as to form a heat dissipation gap between the controller assembly body and the vehicle body.

[0009] By adopting the above technical solution, since the connecting arms are downwardly extended and one end of the connecting arm far from the controller assembly body is used for connecting to the vehicle body, a heat dissipation gap is formed between the controller assembly body and the vehicle body, thus avoiding the situation that the controller assembly body touches the vehicle body and affects heat dissipation, and further improving the heat dissipation effect of the controller assembly body; at the same time, it can also improve the vibration isolation effect of the vehicle-mounted controller assembly to reduce the influence of the vehicle body vibration on the vehicle-mounted controller assembly.

[0010] Optionally, the connecting arm includes a supporting section provided on the controller assembly body and a connecting section provided at an end of the supporting section far from the controller assembly body, and the connecting section is located outside the supporting section.

[0011] By adopting the above technical solution, since the connecting section is located outside the supporting section, it can achieve the effect of facilitating the installation of the vehicle-mounted controller assembly on the vehicle body, so as to reduce the installation difficulty of the vehicle-mounted controller assembly and improve the installation efficiency of the vehicle-mounted controller assembly.

[0012] Optionally, the supporting section extends in a direction away from the connecting end and is connected to the air supply channel.

[0013] By adopting the above technical solution, since the supporting section extends in a direction away from the connecting end and is connected to the air supply channel, the stability of the air supply channel is increased, and at the same time, the fixing difficulty of the air supply channel is reduced.

[0014] Optionally, a closing plate is provided at the air inlet, and the closing plate is movably connected to the air supply channel, so that the closing plate has an open position for opening the air inlet and a closed position for closing the air inlet, and a driving member for driving the closing plate to move between the open position and the closed position is provided on the air supply channel.

[0015] By adopting the above technical solution, when the vehicle is just started or in a low-temperature state, the closing plate is in the closed position, so that the air flow cannot blow towards the overall controller body through the air supply channel, so that the overall controller body is in a better working temperature to ensure the normal operation of the overall controller body; when the temperature of the overall controller body rises, the driving member drives the closing plate so that the closing plate moves to the open position, so that the air flow can enter the air supply channel through the air inlet and blow towards the overall controller body through the air outlet, so as to realize the heat dissipation of the overall controller body, and further the heat dissipation or heat preservation of the overall controller body can be realized through the setting of the control program; in addition, the driving member can also adjust the closing plate to adjust the air intake at the air inlet, so as to realize high-intensity or low-intensity heat dissipation for the overall controller body.

[0016] Optionally, the closing plate is hinged to the air supply channel, and the driving member is used to drive the closing plate to rotate.

[0017] By adopting the above technical solution, since the closing plate is hinged to the air supply channel, the movement mode of the closing plate when opening or closing the air inlet is simplified, so as to increase the stability of the closing plate and at the same time increase the closing effect of the closing plate on the air inlet.

[0018] Optionally, the air inlet is located at the bottom of the vehicle, and the air inlet is located in the plane where the lowest point of the vehicle chassis is located.

[0019] By adopting the above technical solution, since the air inlet is located at the bottom of the vehicle, the length of the air supply channel is shortened, so as to reduce the production cost of the in-vehicle controller assembly, further reduce the manufacturing cost of the vehicle, and at the same time can quickly cool the overall controller body.

[0020] Optionally, the air supply channel has an air supply section parallel to the extending direction of the overall controller body and an air inlet section inclined downward from top to bottom towards the front of the vehicle. A filter screen is arranged in the air inlet section, and the filter screen is arranged perpendicular to the length direction of the air inlet section.

[0021] By adopting the above technical solution, since the air supply section is inclined downward from top to bottom towards the front of the vehicle, the air flow is smoother when entering the air supply channel through the air inlet, so as to ensure the heat dissipation effect on the overall controller body. At the same time, the filter screen is arranged perpendicular to the length direction of the air inlet section, so that the filter screen can filter the air flow entering the air supply channel, so as to avoid the situation that dust in the air flow adheres to the inner wall of the air supply channel and affects the flow area of the air supply channel, so as to further ensure the heat dissipation effect on the controller assembly.

[0022] Optionally, a guide plate is provided at the bottom of the filter screen in the air inlet section. An air flow gap is formed between one end of the guide plate close to the front of the vehicle and the inner wall of the air inlet section. The guide plate is arranged parallel to the filter screen, and a dust discharge port is provided on one side of the air inlet section facing away from the advancing direction of the vehicle. The bottom edge of the dust discharge port is flush with the end face of the guide plate.

[0023] By adopting the above technical solution, after the air flow enters the air supply channel through the air inlet, it flows along the extending direction of the air supply channel, then continues to flow through the air flow gap and contacts the filter screen. Finally, the air flow passing through the filter screen blows towards the controller total body through the air outlet. When the air flow stops entering the air supply channel, the dust on the filter screen falls onto the guide plate under the action of its own gravity and is discharged through the dust discharge port along the guide plate, so as to avoid the situation where dust cannot be discharged from the air supply channel, thereby increasing the cleanliness of the air supply channel.

[0024] Optionally, a flow guide plate is provided at the bottom of the guide plate. The flow guide plate has a first end connected to the inner wall of the air inlet section away from the front of the vehicle and a second end connected to one end of the guide plate close to the front of the vehicle. The first end is spaced from the guide plate.

[0025] By adopting the above technical solution, after the air flow enters the air supply channel, it flows to the air flow gap under the action of the flow guide plate and continues to flow through the air flow gap. Through the setting of the flow guide plate, the air flow can flow more smoothly, so as to greatly improve the heat dissipation effect on the controller total body. At the same time, the flow guide plate can also increase the connection strength between the guide plate and the air supply channel to increase the stability of the guide plate.

[0026] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0027] 1. The vehicle-mounted controller assembly in this application includes a controller total body and an air supply channel. The controller total body has a connection end provided with a connector socket and an avoidance end opposite to the connection end. The air supply channel has an air inlet and an air outlet. The air outlet is arranged opposite to the avoidance end. The air inlet is located at the front or bottom of the vehicle, so that during the forward movement of the vehicle, the air flow can enter the air supply channel through the air inlet and blow towards the controller total body through the air outlet; when the vehicle equipped with the vehicle-mounted controller assembly in this application is running, the air flow enters the air supply channel through the air inlet and blows towards the controller total body through the air outlet, thereby realizing the heat dissipation of the controller assembly. And this application uses the air flow during the forward movement of the vehicle to dissipate heat from the controller total body, avoiding the situation of needing to set up a coolant circulation system, thereby reducing the manufacturing cost of the vehicle.

[0028] 2. On both opposite sides of the overall controller body in this application, connecting arms are provided and extend downward. One end of the connecting arm far from the overall controller body is used to connect to the vehicle body, so as to form a heat dissipation gap between the overall controller body and the vehicle body, thereby avoiding the situation that the overall controller body touches the vehicle body and affects heat dissipation, and further improving the heat dissipation effect of the overall controller body; at the same time, it can also improve the vibration isolation effect of the vehicle-mounted controller assembly to reduce the influence of the vehicle body vibration on the vehicle-mounted controller assembly.

[0029] 3. The connecting arm in this application includes a support section provided on the overall controller body and a connecting section provided at the end of the support section far from the overall controller body.

Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.

[0041] Refer to Figures 1 to 3 , a vehicle-mounted controller assembly with a heat dissipation mechanism is disclosed, which includes a controller total body 1 and an air supply channel 2. The controller total body 1 has a connection end provided with a connector socket and an avoidance end opposite to the connection end. The air supply channel 2 has an air inlet 229 and an air outlet 211. The air outlet 211 is arranged opposite to the avoidance end. The air inlet 229 is located at the front or bottom of the vehicle, so that during the forward movement of the vehicle, the air flow can enter the air supply channel 2 through the air inlet 229 and blow towards the controller total body 1 through 211.

[0042] When the vehicle equipped with the vehicle-mounted controller assembly of the present application is running, the air flow enters the air supply channel 2 through the air inlet 229 and blows towards the controller assembly body 1 through the air outlet 211, thereby realizing the heat dissipation of the controller assembly. Moreover, the present application utilizes the air flow during the forward movement of the vehicle to dissipate heat from the controller assembly body 1, avoiding the situation of needing to set up a coolant circulation system, and thus reducing the manufacturing cost of the vehicle.

[0043] In a preferred embodiment, referring to Figure 1 and Figure 2 , connecting arms 11 are provided and extend downward on both opposite sides of the controller assembly body 1. One end of the connecting arm 11 far from the controller assembly body 1 is used to connect to the vehicle body, so as to form a heat dissipation gap between the controller assembly body 1 and the vehicle body, thereby avoiding the situation that the controller assembly body 1 abuts against the vehicle body and affects heat dissipation, and further improving the heat dissipation effect of the controller assembly body 1; at the same time, it can also improve the vibration isolation effect of the vehicle-mounted controller assembly to reduce the influence of the vehicle body vibration on the vehicle-mounted controller assembly.

[0044] Furthermore, referring to Figure 1 and Figure 2 , heat dissipation fins 12 are provided on both the top and bottom of the controller assembly body 1 to increase the self-heat dissipation ability of the controller assembly body 1.

[0045] Furthermore, referring to Figure 1 and Figure 2 , the connecting arm 11 includes a support section 111 provided on the controller assembly body 1 and a connecting section 112 provided at the end of the support section 111 far from the controller assembly body 1. It can be understood that the connecting section 112 is used to connect to the vehicle body, and the connecting section 112 is located outside the support section 111, thereby being able to achieve the effect of facilitating the installation of the vehicle-mounted controller assembly on the vehicle body, reducing the installation difficulty of the vehicle-mounted controller assembly, and improving the installation efficiency of the vehicle-mounted controller assembly.

[0046] Furthermore, referring to Figure 1 and Figure 2 , the support section 111 extends in a direction away from the connecting end and is connected to the air supply channel 2.

[0047] Specifically, the extended parts of the two support sections 111 are respectively located on both sides of the air supply channel 2, so that the extended parts of the two support sections 111 can clamp the air supply duct, and at the same time, the air supply channel 2 can be fixedly connected to the extended part of the support section 111 by using fasteners, thereby increasing the stability of the air supply channel 2 and reducing the fixing difficulty of the air supply channel 2.

[0048] In a preferred embodiment, referring toFigure 2 and Figure 3 At the air inlet 229, a closing plate 221 is provided. The closing plate 221 is movably connected to the air supply channel 2, so that the closing plate 221 has an open position for opening the air inlet 229 and a closed position for closing the air inlet 229. The air supply channel 2 is provided with a driving member 222 for driving the closing plate 221 to move between the open position and the closed position.

[0049] When the vehicle is just started or in a low-temperature state, the closing plate 221 is in the closed position, so that the air flow cannot blow towards the controller main body 1 through the air supply channel 2, so that the controller main body 1 is in a better working temperature to ensure the normal operation of the controller main body 1; and when the temperature of the controller main body 1 rises, the driving member 222 drives the closing plate 221, so that the closing plate 221 moves to the open position, so that the air flow can enter the air supply channel 2 through the air inlet 229 and blow towards the controller main body 1 through the air outlet, so as to realize the heat dissipation of the controller main body 1, and further the heat dissipation or heat preservation of the controller main body 1 can be realized through the setting of the control program; in addition, the driving member 222 can also adjust the movement stroke of the closing plate 221 to adjust the air intake at the air inlet 229, so as to realize high-intensity or low-intensity heat dissipation for the controller main body 1.

[0050] This application does not specifically limit the movable connection manner between the closing plate 221 and the air supply channel 2. Preferably, referring to Figure 2 and Figure 3 The closing plate 221 is hinged to the air supply channel 2, and the driving member 222 is used to drive the closing plate 221 to rotate, thereby simplifying the movement manner when the closing plate 221 opens or closes the air inlet 229, so as to increase the stability of the closing plate 221 and at the same time increase the closing effect of the closing plate 221 on the air inlet 229.

[0051] This application does not specifically limit the structure of the driving member 222. Preferably, referring to Figure 2 and Figure 3 The driving member 222 is a cylinder or an electric push rod. The cylinder body of the driving member 222 is hinged to the inner wall of the air supply channel 2, and the piston rod of the driving member 222 is hinged to the closing plate 221, so that when the driving member 222 makes an extending movement, the closing plate 221 rotates towards the outside of the air supply channel 2 to open the air inlet 229, and when the driving member 222 makes a retracting movement, the closing plate 221 rotates towards the inside of the air supply channel 2 to close the air inlet 229. In other embodiments, the driving member 222 can also be a matching structure of a motor and a gear.

[0052] In other embodiments, the closing plate 221 may also be movably connected to the air supply channel 2 by sliding, that is, the driving member 222 is used to drive the closing plate 221 to slide, so that the closing plate 221 moves between the open position and the closed position.

[0053] In a preferred embodiment, the air inlet 229 is located at the bottom of the car, and the air inlet 229 is located in the plane where the lowest point of the car chassis is located, thereby shortening the length of the air supply channel 2 to reduce the production cost of the vehicle-mounted controller assembly, to further reduce the manufacturing cost of the car, and at the same time can quickly cool the controller assembly 1.

[0054] Further, see Figure 2 and Figure 3 The air supply channel 2 has an air supply section 21 parallel to the extension direction of the controller assembly 1 and an air inlet section 22 arranged from top to bottom inclined toward the front of the car, so that the airflow enters the air supply channel 2 through the air inlet 229 more smoothly to ensure the heat dissipation effect of the controller assembly 1. A filter 223 is arranged in the air inlet section 22, and the filter 223 is arranged perpendicular to the length direction of the air inlet section 22, so that the filter 223 can filter the airflow entering the air supply channel 2 to avoid dust in the air flow adhering to the inner wall of the air supply channel 2 and affecting the flow area of ​​the air supply channel 2, so as to further ensure the heat dissipation effect of the controller assembly.

[0055] Further, see Figure 2 and Figure 3 A guide plate 226 is provided in the air inlet section 22 and is located at the bottom of the filter screen 223. An air flow gap is formed between the end of the guide plate 226 close to the front of the car and the inner wall of the air inlet section 22. The guide plate 226 is arranged parallel to the filter screen 223, and a dust exhaust port 228 is provided on the side of the air inlet section 22 away from the forward direction of the car, and the bottom edge of the dust exhaust port 228 is flush with the end surface of the guide plate 226.

[0056] It is understandable that the bottom edge of the dust exhaust port 228 is flush with the top end surface of the guide plate 226 .

[0057] Specifically, after the air flow enters the air supply channel 2 through the air inlet 229, it flows along the extension direction of the air supply channel 2, and then continues to flow through the air flow gap and contacts the filter 223, and finally makes the air flow passing through the filter 223 blow toward the controller assembly 1 through the air outlet 211. When the air flow stops entering the air supply channel 2, the dust on the filter 223 falls to the guide plate 226 under the action of its own gravity and is discharged along the guide plate 226 through the dust exhaust port 228, so as to avoid the situation where the dust cannot be discharged from the air supply channel 2, thereby increasing the cleanliness of the air supply channel 2.

[0058] It should be noted that a door can also be provided at the dust exhaust port 228 to open or close the dust exhaust port 228, so that when the overall controller body 1 is cooled, more airflows can blow towards the overall controller body 1, greatly increasing the heat dissipation effect of the overall controller body 1. When the cooling of the overall controller body 1 stops, the door opens the dust exhaust port 228 to enable dust to be discharged through the dust exhaust port 228.

[0059] Preferably, referring to Figure 3 , the filter net 223 has a bent guiding section 224 and a filtering section 225 capable of filtering airflows. The filtering section 225 is arranged perpendicular to the length direction of the air inlet section 22. The guiding section 224 is arranged opposite to the air gap, and the filtering section 225 is arranged opposite to the guiding plate 226. That is to say, the filtering section 225 is provided with a hole structure, and the guiding section 224 is a closed and bent plate-like structure. When the airflow moves to the filter net 223, the guiding section 224 guides the airflow so that the airflow moves to the filtering section 225 and filters the airflow, and avoids the situation where the dust blocked by the filter net 223 falls to the air inlet 229 through the air gap, thereby ensuring that the dust can be discharged through the dust exhaust port 228.

[0060] Furthermore, referring to Figure 2 and Figure 3 , a flow guiding plate 227 is provided at the bottom of the guiding plate 226. The flow guiding plate 227 has a first end connected to the inner wall of the air inlet section 22 far from the front of the vehicle and a second end connected to the end of the guiding plate 226 close to the front of the vehicle. The first end is spaced from the guiding plate 226.

[0061] After the airflow enters the air supply channel 2, it flows to the air gap under the action of the flow guiding plate 227 and continues to flow through the air gap. Through the setting of the flow guiding plate 227, the flow of the airflow can be made smoother, greatly improving the heat dissipation effect of the overall controller body 1. At the same time, the flow guiding plate 227 can also increase the connection strength between the guiding plate 226 and the air supply channel 2 to increase the stability of the guiding plate 226.

[0062] Preferably, referring to Figure 2 and Figure 3 , the flow guiding plate 227 is a bent plate-like structure to increase the guiding effect on the airflow, so that the airflow flows more smoothly in the air supply channel 2, further increasing the heat dissipation effect of the overall controller body 1. At the same time, it can also reduce the noise when the airflow flows in the air supply channel 2, greatly improving the quality of the vehicle.

[0063] Of course, in other embodiments, the air inlet 229 can also be provided at the front of the vehicle, so that when the vehicle moves forward, the air inlet 229 faces the wind directly, thereby greatly improving the heat dissipation efficiency of the overall controller body 1.

[0065] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0066] The above description is only for the embodiments of this application and is not intended to limit this application. For those skilled in the art, various changes and modifications can be made to this application.
