Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the cockpit domain controller of this utility model embodiment includes: a first housing 1, a second housing 2, a first circuit board 3, and a cover plate 4. The first housing 1 has an accommodating space and a first opening and a second opening communicating with the accommodating space, the first opening and the second opening having different orientations. For example, the first opening is located on the top surface of the first housing 1, and the second opening is located on the side surface of the first housing 1, the first opening and the second opening communicating with each other. Additionally, a first mounting surface is provided within the accommodating space. For example, the first mounting surface is formed on the three side walls of the first housing 1 by etching, thus the first mounting surface can be U-shaped, and the first mounting surface corresponds to the first opening.

[0044] The second housing 2 is provided with a first flange 21. For example, the second housing 2 is integrally provided with the first flange 21. The second housing 2 is adapted to the first opening and covers the first opening. At this time, the first flange 21 is interference-fitted with the first outer side surface of the first housing 1. The first circuit board 3 is sandwiched between the second housing 2 and the first mounting surface, and the first copper-plated area of ​​the first circuit board 3 abuts against the second housing 2. The first copper-plated area is provided on the front side of the first circuit board 3, and the first copper-plated area can be located close to the edge of the first circuit board 3.

[0045] The cover plate 4 is provided with a second flange 41 and a third flange 42 arranged opposite to each other. For example, the cover plate 4 is integrally provided with the second flange 41 and the third flange 42. The cover plate 4 is adapted to the second opening and covers the second opening. The second flange 41 is interference-fitted with the top surface of the second housing 2, and the third flange 42 is interference-fitted with the bottom surface of the first housing 1. Here, the top surface of the second housing 2 refers to the side of the second housing 2 that is away from the accommodating space.

[0046] It should be noted that a second protrusion 411 is provided on the side of the second flange 41 facing the top surface of the second housing 2. Similarly, a third protrusion is provided on the side of the third flange 42 facing the bottom surface of the first housing 1. Both the second protrusion 411 and the third protrusion can be multiple protrusions.

[0047] In practical applications, the interference fit between the second flange 41 of the cover plate 4 and the top surface of the second housing 2, combined with the interference fit between the third flange 42 and the bottom surface of the first housing 1, ensures that the cover plate 4, the first housing 1, and the second housing 2 are tightly connected, enhancing the overall anti-interference capability. The compression of the second flange 41 on the second housing 2 causes it to undergo controllable deformation, completely eliminating the assembly contact gap between the second housing 2 and the first copper-clad area of ​​the first circuit board 3, significantly enhancing the grounding shielding effect of the first circuit board 3. The interference fit between the first flange 21 of the second housing 2 and the first outer surface of the first housing 1 further ensures the stability of the connection between the two, achieving a reliable connection, and ultimately forming a complete shielding cavity for the entire machine, continuously enhancing the anti-interference performance. In this way, the electromagnetic compatibility and reliability of the entire machine are comprehensively improved.

[0048] In optional embodiments, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a first protrusion 211 is integrally formed on the side of the first flange 21 facing the first outer side. Specifically, the first protrusion 211 is integrally formed on the side of the first flange 21 facing the first outer side. The first protrusion 211 has a specific shape and size, and its shape can be designed according to actual assembly requirements and mechanical performance requirements, such as being semi-circular, trapezoidal, or rectangular. In this embodiment, the first protrusion 211 is semi-circular.

[0049] It is understandable that the first protrusion 211 can improve contact stability when the first flange 21 and the first outer surface are engaged, and can also improve the overall electromagnetic shielding effect to a certain extent.

[0050] In optional embodiments, such as Figure 6 and Figure 7 As shown, the first protrusion 211 includes protrusions, and a plurality of protrusions are spaced apart along the length direction of the first flange 21.

[0051] It should be noted that, in order to achieve a more reliable and stable connection between the first flange 21 and the first outer side, a first protrusion 211 is provided on the side of the first flange 21 facing the first outer side. The first protrusion 211 is composed of multiple protrusions, and the multiple protrusions are spaced apart along the length direction of the first flange 21.

[0052] For example, the first flange 21 has a length of 120 mm and is provided with 10 protrusions, with a spacing of 12 mm between adjacent protrusions. During the manufacturing process, the protrusions and the first flange 21 are made simultaneously using an integral molding process, ensuring the connection strength and structural stability between the protrusions and the first flange 21. For example, the protrusions can be formed on the first flange 21 by a stamping process.

[0053] Understandably, during assembly, when the first flange 21 of the second housing 2 is brought close to the first outer surface of the first housing 1, the protrusions will interact with the first outer surface as they gradually approach each other. Since the protrusions are spaced apart, this force can be evenly distributed across the entire first flange 21, avoiding structural damage caused by excessive local stress.

[0054] In optional embodiments, such as Figure 8 and Figure 9 As shown, the first protrusion 211 includes a ridge extending along the height direction of the first flange 21, and a plurality of protrusions are spaced apart along the length direction of the first flange 21. Alternatively, the first protrusion 211 includes a ridge extending along the length direction of the first flange 21, and a plurality of protrusions are spaced apart along the height direction of the first flange 21.

[0055] It should be noted that, in order to achieve a more reliable and stable connection between the first flange 21 and the first outer surface, a first protrusion 211 is provided on the side of the first flange 21 facing the first outer surface. The first protrusion 211 includes a ridge extending along the height direction of the first flange 21, and multiple ridges are spaced apart along the length direction of the first flange 21.

[0056] For example, the first flange 21 has a height of 20 mm and a length of 100 mm. The convex strip has a width of 2 mm and a height of 20 mm, the same as the first flange 21. The convex strip is manufactured simultaneously with the first flange 21 using an integral molding process, ensuring the connection strength and structural stability between the convex strip and the first flange 21. For example, the convex strip can be formed on the first flange 21 by a stamping process.

[0057] Understandably, the first flange 21, after being processed by the folding and pressing process, forms a raised strip structure, which significantly increases the contact area between the first housing 1 and the second housing 2, resulting in more thorough contact between them. This greatly improves the overall anti-interference performance of the structure and effectively reduces the high-frequency impedance of the contact surface. Simultaneously, it mitigates the effects of the skin effect on high-frequency signals, thereby achieving a more reliable electromagnetic shielding effect for the entire device.

[0058] In optional embodiments, such as Figure 1 As shown, there are two first flanges 21, which are arranged opposite to each other. It should be noted that the first housing 1 has two first flanges 21, which are arranged opposite to each other. For example, the first flanges 21 are formed by a folding and pressing process, forming a raised strip structure after folding and pressing.

[0059] In practical applications, two opposing first flanges 21 are located at the two side edges of the first housing 1, with their length direction parallel to the side edges of the first housing 1. During assembly, the second housing 2 is connected to the first housing 1 via the two opposing first flanges 21. This improves the connection stability between the first housing 1 and the second housing 2.

[0060] In optional embodiments, such as Figure 3 and Figure 4 As shown, the second housing 2 is also provided with a fourth flange 22, which abuts against the first copper-clad area of ​​the first circuit board 3; the bottom surface of the second housing 2 is also provided with a recess 23, and the first circuit board 3 is sandwiched between the recess 23 and the first mounting surface.

[0061] It should be noted that the second housing 2 is provided with a fourth flange 22, which extends towards the interior of the accommodating space. The surface of the fourth flange 22 has undergone special treatment, exhibiting good conductivity and flatness. The fourth flange 22 abuts against the first copper-clad area of ​​the first circuit board 3, which is a conductive area on the first circuit board 3 specifically used for electromagnetic shielding and signal transmission. The tight contact between the fourth flange 22 and the first copper-clad area can effectively guide electromagnetic interference from the first circuit board 3 to the second housing 2, enhancing the electromagnetic shielding effect of the device.

[0062] Meanwhile, the bottom surface of the second housing 2 is also provided with a recess 23, which can be formed by stamping and is located at the edge of the first circuit board 3. During the installation process, the first circuit board 3 is first placed on the first mounting surface, and then the first housing 1 and the second housing 2 are assembled so that the first circuit board 3 is firmly clamped between the recess 23 and the first mounting surface. Finally, fasteners are sequentially inserted into the recess 23, the first circuit board 3 and the fixing seat provided in the accommodating space to fix and install the first circuit board 3.

[0063] In optional embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, a first elastic element 221 is provided on the side of the fourth flange 22 facing the first copper-clad area, and the first elastic element 221 is interference-fitted with the first copper-clad area. For example, the first elastic element 221 includes a base and a first cantilever and a second cantilever, which are located on opposite sides of the base. Both the first cantilever and the second cantilever can be V-shaped structural members.

[0064] It should be noted that a first elastic element 221 is provided on the side of the fourth flange 22 facing the first copper-clad area. The first elastic element 221 has good elasticity. The first elastic element 221 is installed with the first copper-clad area by an interference fit. The interference fit causes the first elastic element 221 to be in a compressed state after installation, thereby generating a certain elastic force to ensure that the first elastic element 221 and the first copper-clad area always maintain close contact. In other words, the first circuit board 3 achieves its shielding effect by coordinating the elastic deformation of the first elastic element 221 with the grounding of the first copper-clad area.

[0065] In optional embodiments, such as Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the second housing 2 is also provided with a fifth flange 24, which is arranged opposite to the fourth flange 22. The fifth flange 24 abuts against at least one of the inner wall surface of the accommodating space and the second outer surface of the first housing 1; wherein the second outer surface is arranged adjacent to the first outer surface.

[0066] It should be noted that the fifth flange 24 is arranged opposite to the fourth flange 22. The fifth flange 24 can abut against at least one of the inner wall surface of the accommodating space and the second outer surface of the first housing 1, which can enhance the connection stability between the second housing 2 and the first housing 1. At the same time, it further increases the tightness of the connection between the first housing 1 and the second housing 2, forming a continuous electromagnetic shielding barrier, effectively preventing the entry of external electromagnetic interference and the leakage of internal electromagnetic signals.

[0067] In optional embodiments, such as Figure 10 and Figure 11 As shown, the fifth flange 24 includes a first bent portion 241 extending obliquely from the second housing 2, a first horizontal portion 242 extending horizontally from the first bent portion 241, and a first vertical portion 243 extending bently from the first horizontal portion 242. The first vertical portion 243 is interference-fitted with the inner wall surface of the accommodating space. A corresponding protrusion is provided on the side of the first vertical portion 243 that contacts the inner wall surface of the accommodating space.

[0068] It should be noted that the fifth flange 24 includes a first bent portion 241 extending obliquely from the second housing 2, a first horizontal portion 242 extending horizontally from the first bent portion 241, and a first vertical portion 243 extending bently from the first horizontal portion 242. For example, the first bent portion 241 extends obliquely at a 120° angle to the main body of the second housing 2. The horizontal extension of the first horizontal portion 242 provides a stable support base for the first vertical portion 243 and also increases the contact area between the first horizontal portion 242 and the first circuit board 3. The first vertical portion 243 extends perpendicularly to the first horizontal portion 242. The first vertical portion 243 is interference-fitted with the inner wall of the accommodating space, ensuring a tight fit between the first vertical portion 243 and the inner wall of the accommodating space after installation, thus enhancing structural stability. Simultaneously, the tight fit also forms an effective electromagnetic shielding barrier, preventing the entry of external electromagnetic interference and the leakage of internal electromagnetic signals. In this way, a double shielding structure is formed between the second housing 2 and the first circuit board 3, and between the first housing 1 and the second housing 2. Interference signals are attenuated by the double shielding structure, preventing a large number of electromagnetic waves from entering the device.

[0069] In optional embodiments, such as Figure 12 and Figure 13 As shown, the fifth flange 24 includes a second bent portion 244 extending obliquely from the second housing 2, a second horizontal portion 245 extending horizontally from the second bent portion 244, a second vertical portion 246 extending bently from the second horizontal portion 245, a third horizontal portion 247 extending bently from the second vertical portion 246, and a third vertical portion 248 extending bently from the third horizontal portion 247. The sidewall of the first housing 1 is sandwiched within the space enclosed by the second vertical portion 246, the third horizontal portion 247, and the third vertical portion 248. A corresponding protrusion is provided on the side of the second vertical portion 246 that contacts the sidewall of the first housing 1, and a corresponding protrusion is provided on the side of the third vertical portion 248 that contacts the sidewall of the first housing 1.

[0070] It should be noted that the fifth flange 24 includes a second bent portion 244 extending obliquely from the second housing 2, a second horizontal portion 245 extending horizontally from the second bent portion 244, a second vertical portion 246 extending bently from the second horizontal portion 245, a third horizontal portion 247 extending bently from the second vertical portion 246, and a third vertical portion 248 extending bently from the third horizontal portion 247. For example, the second bent portion 244 extends obliquely at a 120° angle to the main body of the second housing 2. The horizontal extension of the second horizontal portion 245 provides a stable support foundation for the subsequent bending structure and also increases the contact area between the second horizontal portion 245 and the first circuit board 3. The second vertical portion 246 extends perpendicularly to the second horizontal portion 245, and the second vertical portion 246, the third horizontal portion 247, and the third vertical portion 248 together enclose a specific space. The sidewalls of the first housing 1 are sandwiched within the space enclosed by the second vertical portion 246, the third horizontal portion 247, and the third vertical portion 248, forming a tight mechanical connection between the first housing 1 and the second housing 2, greatly enhancing the structural stability of the equipment. Furthermore, this creates a triple shielding structure, making the propagation path of electromagnetic waves more complex, resulting in multiple reflections and absorptions, thus achieving a better shielding effect.

[0071] In optional embodiments, such as Figure 14 and Figure 15 As shown, a second mounting surface is also provided within the accommodating space, wherein the second mounting surface is located below the first mounting surface. For example, the second mounting surface is constructed by forming a mounting base within the accommodating space. The cockpit domain controller also includes: a second circuit board 5, a bracket 6, and a connector 7. The second circuit board 5 is disposed on the second mounting surface; the bracket 6 is disposed within the accommodating space, and the bracket 6 is used to connect the second copper-clad area of ​​the first circuit board 3 and the third copper-clad area of ​​the second circuit board 5, wherein the first copper-clad area and the second copper-clad area are respectively disposed on opposite sides of the first circuit board 3; the connector 7 is disposed within the accommodating space, and the bracket 6 is provided with a second elastic member 61, the second elastic member 61 being interference-fitted with the metal portion of the connector 7.

[0072] Specifically, the bracket 6 includes a side plate and a base plate, which are arranged approximately vertically. The base plate has a sixth flange, and the side plate and the sixth flange are located on opposite sides of the base plate. The side plate abuts against the second copper-plated area of ​​the first circuit board 3, and the sixth flange abuts against the third copper-plated area of ​​the second circuit board 5. A second elastic member 61 is disposed on the base plate and includes a connecting portion, an inclined portion extending from the connecting portion, and an abutting portion extending from the inclined portion. The connecting portion is disposed on the base plate, and the abutting portion is press-fitted with the metal portion of the connector 7. It is particularly noteworthy that the cover plate 4 has a through hole corresponding to the connector 7, allowing the connector 7 to pass through the through hole.

[0073] In practical applications, in order to increase the grounding effect of connector 7 and reduce the EMC interference caused by external high-frequency interference signals entering the product through the connector, the interference signals are quickly discharged to the ground through the path of "connector 7-bracket 6-second housing 2-first housing 1", which reduces the interference signals entering the circuit board, improves the weak point of the directional shielding of connector 7, and reduces the risk of electromagnetic interference.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
