[0030] The following is for reference. Figures 1-2 The circuit board assembly 100 according to the present invention is simple in structure, easy to install, and has low setup cost. It can improve EMC shielding performance, ensure vehicle operation stability, and thus improve safety.

[0031] like Figures 1-2 As shown, a circuit board assembly 100 according to an embodiment of the present invention includes: a circuit board 1 and a shielding housing 2.

[0032] The circuit board 1 includes a main body region 11 and a copper-plated region 12. The copper-plated region 12 is located outside the main body region 11. A shielding shell 2 is installed over the main body region 11. The shielding shell 2 is connected to the copper-plated region 12, and at least a portion of the copper-plated region 12 is located outside the shielding shell 2. A conductive seal 4 is provided between the shielding shell 2 and the copper-plated region 12.

[0033] Specifically, the circuit board assembly 100 includes a circuit board 1, which refers to a printed circuit board used in the vehicle's electronic control system. The printed circuit board plays a crucial role in the vehicle's electrical system, directly affecting its performance and safety. It houses various electronic components and chips, used for transmitting, controlling, and processing various electrical signals and data. Printed circuit boards can improve vehicle performance and energy efficiency to save energy, and can also optimize vehicle safety and ensure vehicle reliability.

[0034] Furthermore, the circuit board 1 is provided with a main body area 11, and multiple traces are provided inside the main body area 11 so that the circuit board 1 can be connected to different networks through multiple traces to realize the transmission of electrical signals and data through the circuit board 1, ensuring the stability of vehicle operation. The circuit board 1 is also provided with a copper-clad area 12, which is located outside the main body area 11. The copper-clad area 12 can be set as a ring structure or multiple block areas, etc., which can be set according to the actual shape of the circuit board 1, and the setting method is flexible. And setting the copper-clad area 12 outside the main body area 11 facilitates the connection between the copper-clad area 12 and the ground wire, etc., ensuring the reliability of the circuit board 1.

[0035] In this way, the circuit board 1 can be connected to the ground line through the copper-plated area 12, thereby reducing the loop area, improving the stability and reliability of the circuit, and reducing the voltage drop in the circuit, thereby improving the power supply efficiency. Copper also has good conductivity, which can effectively carry current and reduce the loss of electrical energy during transmission. At the same time, copper plating of part of the circuit board 1 can increase the mechanical strength of the circuit board 1, thereby preventing the circuit board 1 from deforming during the soldering process and ensuring the operational stability of the circuit board 1.

[0036] Furthermore, the circuit board assembly 100 is also provided with a shielding shell 2, which can be covered on the main body area 11. The shielding shell 2 can be connected to the copper-clad area 12 through connectors, etc. The shielding shell 2 is made of a material with shielding function, so that the shielding shell 2 can absorb and conduct external electromagnetic interference, such as electromagnetic waves or static electricity. An insulating withstand voltage layer can be provided on the shielding shell 2, so that the shielding shell 2 can prevent the high voltage current diffused by external components from breaking down the circuit board 1, thereby ensuring the operational stability of the circuit board 1.

[0037] Meanwhile, the shielding shell 2 is installed on the outside of the main body area 11, that is, the shielding shell 2 can protect the main body area 11, ensure the operational stability of the main body area 11, extend the service life of the circuit board 1, and at least part of the copper-plated area 12 is located outside the shielding shell 2, which can ensure the reliability of the connection between the copper-plated area 12 and the external circuit, thereby ensuring the operational reliability of the circuit board 1.

[0038] In addition, a conductive seal 4 is provided between the shielding housing 2 and the copper-plated area 12. That is, when the shielding housing 2 is installed on the circuit board 1, the conductive seal 4 can seal the gap between the shielding housing 2 and the copper-plated area 12 to ensure the reliability of shielding the main body area 11. The conductive seal 4 is made of conductive material to ensure the reliability of the operation of the circuit board 1.

[0039] In this way, the impedance between the shielding housing 2 and the circuit board 1 can be reduced, which helps to discharge noise on the circuit board 1 to the ground, thereby reducing radiation emission. It can also reduce the gap between the circuit board 1 and the shielding housing 2, thereby reducing the radiation of the circuit board 1 to the outside. At the same time, it can also weaken the external noise interference entering the circuit board 1, enhance the shielding effect, improve the reliability of the shielding housing 2, and thus improve the operational stability of the circuit board 1, so as to ensure the operational stability of the vehicle and improve the safety of use.

[0040] According to the embodiment of the present utility model, the circuit board assembly 100 is provided with a shielding shell 2, which can ensure the operational stability of the circuit board 1. A conductive sealant 4 is provided between the shielding shell 2 and the copper-plated area 12, which can conductively seal the gap between the shielding shell 2 and the copper-plated area 12, thereby improving the EMC shielding performance of the circuit board assembly 100, ensuring the operational stability of the vehicle, improving the safety of use, and having a simple structure, convenient installation, low setup cost, better performance, and wider applicability.

[0041] In some embodiments, the shielding housing 2 and the copper-clad area 12 are detachably connected by a connector 3.

[0042] Specifically, the shielding shell 2 is installed over the main body area 11 and is connected to the copper-clad area 12, so that the shielding shell 2 can shield and protect the main body area 11, ensuring the operational stability of the circuit board 1. The shielding shell 2 is detachably installed on the copper-clad area 12, that is, the shielding shell 2 can be connected to the copper-clad area 12 by means of connectors or snap-fits. In this embodiment, the shielding shell 2 and the copper-clad area 12 are detachably connected by connectors 3. The connectors 3 can be screws or bolts, etc., which have a simple structure and low installation cost, thereby improving the ease of installation. When either the shielding shell 2 or the circuit board 1 is damaged, the shielding shell 2 and the circuit board 1 can be disassembled to replace the damaged part, improving the ease of maintenance and reducing maintenance costs.

[0043] In some embodiments, the shielding housing 2 is provided with a first connection hole 21, the copper-clad area 12 is provided with a second connection hole 121, and the connector 3 is sequentially inserted through the first connection hole 21 and the second connection hole 121.

[0044] Specifically, the shielding housing 2 and the copper-clad area 12 are detachably connected by the connector 3, and as shown in the figure. Figure 1 As shown, the shielding housing 2 may be provided with a first connecting hole 21, and the copper-clad area 12 may be provided with a second connecting hole 121. The first connecting hole 21 is a through hole, and the second connecting hole 121 may be a through hole or a blind hole. The first connecting hole 21 and the second connecting hole 121 are correspondingly provided, and the connector 3 can be sequentially inserted into the first connecting hole 21 and the second connecting hole 121. That is, the connector 3 can pass through the shielding housing 2 into the copper-clad area 12 to detachably connect the shielding housing 2 and the copper-clad area 12. The structure is simple, the installation is convenient, and the connection reliability can be guaranteed.

[0045] Furthermore, the conductive seal 4 is disposed between the shielding housing 2 and the copper-plated area 12, and the inner walls of the first connecting hole 21 and the second connecting hole 121 can be provided with threaded holes. The connector 3 can be configured as a screw or bolt, etc. When the connector 3 is sequentially inserted into the shielding housing 2 and the copper-plated area 12, and as the connector 3 is gradually tightened, the shielding housing 2 can be squeezed into the copper-plated area 12, thereby squeezing the conductive seal 4 located between the shielding housing 2 and the copper-plated area 12 to ensure the sealing performance of the conductive seal 4 in the gap between the shielding housing 2 and the copper-plated area 12, thereby ensuring the reliability of the conductive seal 4 in use.

[0046] In some embodiments, there are multiple first connecting holes 21 and multiple second connecting holes 121, and multiple connectors 3, and the multiple connectors 3, the multiple first connecting holes 21 and the multiple second connecting holes 121 are all provided in a one-to-one correspondence.

[0047] Specifically, the shielding housing 2 is provided with a first connection hole 21, and the copper-clad area 12 is provided with a second connection hole 121, and as shown in the figure. Figure 1 As shown, there are multiple first connection holes 21, i.e., two, three, or four first connection holes 21, and multiple second connection holes 121, i.e., two, three, or four second connection holes 121, and multiple connectors 3, i.e., two, three, or four connectors 3. The multiple connectors 3, multiple first connection holes 21, and multiple second connection holes 121 are all arranged in a one-to-one correspondence, i.e., the number of first connection holes 21, second connection holes 121, and connectors 3 are all equal, so that each connector 3 can be sequentially inserted into the first connection hole 21 and the second connection hole 121, so that the shielding shell 2 and the copper-clad area 12 can be detachably connected, making installation convenient.

[0048] Thus, by setting multiple first connection holes 21 and second connection holes 121, multiple parts of the shielding housing 2 can be connected to the copper-plated area 12 through the connector 3, thereby improving the connection reliability and reducing the distance between two adjacent connectors 3, thereby reducing the gap between the shielding housing 2 and the copper-plated area 12, facilitating sealing, improving the shielding effect of the shielding housing 2, and improving the reliability of the circuit board 1.

[0049] In some embodiments, the copper-clad region 12 is constructed as an annular region, and there are multiple connectors 3, which are spaced apart in the circumferential direction of the copper-clad region 12 to be connected to the shielding housing 2 respectively.

[0050] Specifically, the copper-clad area 12 is located on the outside of the main body area 11, and as shown in the figure. Figure 1As shown, the copper-clad area 12 is set as a ring-shaped area, that is, the copper-clad area 12 surrounds the main body area 11, so that the outer edge of the main body area 11 can contact the copper-clad area 12, thereby improving the conductivity reliability and the structural strength at the edge of the circuit board 1, so as to improve the reliability of the circuit board 1 and extend the service life of the circuit board 1.

[0051] Furthermore, such as Figure 2 As shown, the shielding housing 2 and the copper-clad area 12 can be detachably connected by connectors 3. Multiple connectors 3 can be provided, such as two, three, or four connectors 3. The multiple connectors 3 can be spaced apart in the circumferential direction of the copper-clad area 12. The copper-clad area 12 is set as an annular area, that is, the connectors 3 can be spaced apart along the annular shape, so that all parts of the copper-clad area 12 can be connected to the shielding housing 2 through the connectors 3, which improves the connection reliability and reduces the gap between the shielding housing 2 and the copper-clad structure, ensuring the reliability of the shielding housing 2 in use.

[0052] In some embodiments, the conductive seal 4 is located between two adjacent connectors 3.

[0053] Specifically, the shielding housing 2 is detachably connected to the copper-plated area 12 via the connector 3, and a conductive seal 4 is provided between the shielding housing 2 and the copper-plated area 12, such as... Figures 1-2 As shown, multiple connectors 3 are provided, and the multiple connectors 3 are distributed at intervals to improve the connection reliability between the shielding shell 2 and the copper-plated area 12. A conductive seal 4 is provided between each two adjacent connectors 3, so that the gap between the shielding shell 2 and the copper-plated area 12 located between two adjacent connectors 3 is provided with a conductive seal 4. In this way, all gaps between the shielding shell 2 and the copper-plated area 12 can be sealed to ensure the reliability of the gap sealing, improve the shielding effect of the shielding shell 2, and ensure the operational stability of the circuit board 1.

[0054] In some embodiments, the conductive seal 4 is configured as a solder point, and multiple solder points are provided between two adjacent connectors 3. The solder points are adapted to undergo plastic deformation when the shielding housing 2 and the copper-clad area 12 are connected.

[0055] Specifically, the conductive seal 4 is disposed between the shielding housing 2 and the copper-plated area 12, and the conductive seal 4 can be set as a solder point, that is, the solder can be soldered to the edge of the shielding housing 2 or to the copper-plated area 12. When the shielding housing 2 and the copper-plated area 12 are connected by the connector 3, the shielding housing 2 and the copper-plated area 12 can compress the solder point, so that the solder point can undergo plastic deformation, thereby sealing the gap between the shielding housing 2 and the copper-plated area 12. The solder point can adapt to the size of the gap to improve the sealing reliability.

[0056] In addition, there are multiple connectors 3, and multiple solder points are provided between each pair of adjacent connectors 3. That is, there can be two, three or four solder points between each pair of adjacent connectors 3. The number of solder points is adjusted according to the distance between the two adjacent connectors 3. That is, when the distance between the two adjacent connectors 3 is long, the number of solder points between the two adjacent connectors 3 can be increased, and when the distance between the two adjacent connectors 3 is short, the number of solder points between the two adjacent connectors 3 can be reduced.

[0057] In this way, when the shielding shell 2 and the copper-plated area 12 are connected, each solder point can be plastically deformed to seal the gap between two adjacent connectors 3, improving the reliability of the seal. It can also avoid overflow caused by too many solder points, thus avoiding material waste and reducing the installation cost.

[0058] In some embodiments, the conductive seal 4 is constructed as conductive foam, which extends along the length of the copper-clad region 12 and is adapted to undergo elastic deformation when the shielding housing 2 and the copper-clad region 12 are connected.

[0059] Specifically, the conductive sealing element 4 is disposed between the shielding housing 2 and the copper-plated area 12. The conductive sealing element 4 can be configured as conductive foam, which can be bonded to the edge of the shielding housing 2 or to the copper-plated area 12. When the shielding housing 2 and the copper-plated area 12 are connected by the connector 3, the shielding housing 2 and the copper-plated area 12 can compress the conductive foam, causing it to undergo elastic deformation. This allows the conductive foam to seal the gap between the shielding housing 2 and the copper-plated area 12, and the conductive foam can adapt to the size of the gap to improve sealing reliability.

[0060] In addition, the conductive foam extends along the length of the copper-clad area 12, so that when the shielding shell 2 and the copper-clad area 12 are connected, the conductive foam can seal the various points between the shielding shell 2 and the copper-clad area 12, thereby improving the sealing reliability. Furthermore, the conductive foam can be adjusted according to the shape of the copper-clad area 12, thereby improving the flexibility of the installation and meeting different usage requirements.

[0061] In some embodiments, the copper-clad area 12 is adapted to be connected to the ground line.

[0062] Specifically, the circuit board 1 is provided with a copper-plated area 12, which is suitable for connection to the ground wire. That is, the circuit board 1 can be connected to the ground wire through the copper-plated area 12, thereby reducing the loop area, improving the stability and reliability of the circuit, and reducing the voltage drop in the circuit, thereby improving the power supply efficiency. Copper also has good conductivity, which can effectively carry current and reduce the loss of electrical energy during transmission. Furthermore, the copper-plated area 12 can conduct high-voltage current to the outside of the vehicle, such as the ground, through the ground wire, thereby ensuring the operational stability of the circuit board 1 and preventing high-voltage current from damaging other parts of the vehicle body, thus ensuring the reliability of vehicle operation.

[0063] This utility model also proposes a vehicle.

[0064] The vehicle according to the present invention is provided with a circuit board assembly 100 as described above.

[0065] The vehicle according to this utility model embodiment is provided with a circuit board assembly 100, and the circuit board assembly 100 is provided with a shielding shell 2 to ensure the operational stability of the circuit board 1.
