In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0034] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a controller is provided.

[0035] Specifically, Figure 1 , Figure 2 The controller shown includes: a first shell 10, in which at least one supporting boss 11 is arranged; a second shell 20, which is arranged opposite to the first shell 10, and is connected to the first shell 10, so that a mounting cavity 30 is formed between the second shell 20 and the first shell 10, and at least one mounting gap 31 is formed between the second shell 20 and the at least one supporting boss 11; a circuit board 40, which is located in the mounting cavity 30, and at least a part of the circuit board 40 is located in the mounting gap 31, and a conductive adhesive 41 is arranged in at least one mounting gap 31.

[0036] By applying the technical solution of the present invention, the second shell 20 and the first shell 10 are arranged opposite to each other, the second shell 20 and the first shell 10 are connected, and an installation cavity 30 is formed between the second shell 20 and the first shell 10, and the circuit board 40 is located in the installation cavity 30; a supporting boss 11 is provided in the first shell 10, and an installation gap 31 is formed between the second shell 20 and the supporting boss 11, and a conductive adhesive 41 is provided in the installation gap 31. A part of the circuit board 40 is located in the installation gap 31 to form an electromagnetic shielding cavity, thereby blocking internal and external electromagnetic interference, improving the electromagnetic shielding performance of the whole machine, and solving the problem that the electromagnetic shielding performance of existing controller products is difficult to ensure.

[0037] Through this design, the circuit board can be more firmly fixed in the shell, avoiding displacement of the circuit board due to vibration or impact, and improving the reliability of the controller. This structure is particularly suitable for occasions that are sensitive to electromagnetic interference, such as electric vehicles and self-driving vehicles, to ensure the normal operation of the controller. In practical applications, this unique design greatly reduces the risk of circuit board damage caused by bumps and vibrations during vehicle driving, and has a significant effect on improving the long-term stability of the controller and extending its service life. In electric vehicles and self-driving vehicles, due to the high requirements for electromagnetic compatibility, this design can effectively reduce the impact of external electromagnetic interference on the circuit board and ensure the accurate and correct operation of key electronic systems. In addition, the use of conductive adhesive can also enhance the heat dissipation capacity of the controller, especially in electric vehicles operating at high power, which helps to maintain the system temperature within a safe range and avoid system failures caused by overheating. It should be noted that if Figure 3 As shown, a heat dissipation boss 50 is provided on the first shell, and the heat dissipation boss 50 is provided corresponding to the heating device on the circuit board 40 .

[0038] Optionally, by optimizing the shape and position of the heat dissipation boss 50 through EMC simulation, the resonance generated by the interference signal in the inner cavity of the first shell 10 can be reduced, thereby further improving the electromagnetic shielding performance of the controller.

[0039] Specifically, Figure 2 , Figure 3 There are multiple support bosses 11, which are arranged at intervals on the circumference of the first shell 10, and the circuit board 40 is clamped in the installation gap 31. In this embodiment, three support bosses 11 are arranged in the first shell 10, which are respectively distributed on the three sides of the first shell 10 other than the connector 42. The support bosses 11 can provide additional support around the first shell 10, increase the overall stability of the first shell 10, and make it more able to withstand external pressure and load. The support bosses 11 are arranged on three sides of the first shell 10 to effectively disperse the load on the surface of the first shell 10, and avoid deformation or rupture of the shell due to excessive local stress.

[0040] This layout makes the circuit board more evenly fixed, avoids local stress concentration, and prolongs the service life of the circuit board. When the vehicle is driving at high speed or in complex road conditions, this design can effectively reduce the vibration of the circuit board and maintain its stable operation, and is suitable for electronic control systems of various vehicles.

[0041] The use of spaced support bosses not only enhances the physical fixation of the circuit board, but also optimizes the force distribution of the circuit board, reducing damage to the circuit board caused by excessive local force. This design is particularly prominent in the electronic control systems of various vehicles, especially in high-performance vehicles such as racing cars and high-performance electric vehicles. It can significantly reduce the damage rate of the circuit board during high-speed driving or intense driving, ensuring the stability and safety of the vehicle under extreme conditions. At the same time, this layout also simplifies the installation process of the circuit board and reduces the difficulty and cost of production assembly.

[0042] Specifically, one side of the first housing 10 has a connector cavity 32 for accommodating the connector 42 on the circuit board 40, wherein, among the multiple side walls 12 in the circumferential direction of the first housing 10, a supporting boss 11 is provided on each of the multiple side walls except the side wall 12 where the connector cavity 32 is located. That is, the supporting boss 11 is provided on three side walls except the side wall 12 where the connector cavity 32 is located, and a total of three supporting bosses 11 are provided in the first housing 10.

[0043] Optionally, the connector 42 is a component used to connect different components on the circuit board 40 or to connect the circuit board 40 with other devices. The connector 42 plays a role in connecting and transmitting signals and power so that the circuit board 40 can work normally. The connector 42 usually has a plug-in function to facilitate replacement or maintenance of components on the circuit board 40.

[0044] Optionally, the connector cavity 32 is used to accommodate the plug of the connector 42, ensuring that the plug of the connector 42 can be correctly inserted into the cavity and firmly connected to other devices. The connector cavity 32 is usually designed to a specific shape and size to ensure that the plug can be correctly aligned and inserted, avoiding the occurrence of incorrect insertion or loose plug. Through the design of the connector cavity 32, the connector 42 can achieve the function of reliable connection and signal transmission.

[0045] Specifically, one side of the circuit board 40 in the mounting gap 31 in the thickness direction is fitted with the support boss 11, and the other side of the circuit board 40 in the thickness direction is fitted with the second housing 20. That is, one side of the circuit board 40 in the thickness direction is assembled to the support boss 11 of the first housing 10, and the other side of the circuit board 40 in the thickness direction is assembled to the second housing 20. The upper surface of the support boss 11 is fitted with the circuit board 40, playing the role of supporting the circuit board 40.

[0046] This design not only ensures the stability of the circuit board, but also ensures the normal access of the connector, improving the maintainability and operability of the controller. When the vehicle is repaired or upgraded, this structure can quickly and easily replace the circuit board, which is suitable for vehicle control systems that require frequent maintenance or upgrades.

[0047] The connector cavity provides the necessary installation space and protection for the connector on the circuit board, preventing the connector from being damaged or disturbed during vehicle operation, while ensuring a stable connection with external devices. This design has shown great advantages in the maintenance and upgrade process of the vehicle, especially in commercial trucks and special vehicles, whose electronic systems may require more frequent technical maintenance and equipment updates. The controller design with a connector cavity enables maintenance personnel to quickly replace the circuit board without destroying the entire system, greatly improving the operating efficiency and economic benefits of the vehicle.

[0048] This double-sided bonding design further enhances the stability of the circuit board, and at the same time utilizes the metal material properties of the shell to enhance the electromagnetic shielding effect. It is suitable for vehicle electronic equipment with high requirements for electromagnetic compatibility, such as in-vehicle entertainment systems, navigation systems, etc.

[0049] The double-sided lamination design takes advantage of the metal material properties of the shell to provide additional mechanical support and electromagnetic shielding for the circuit board, which is essential for improving the signal quality and user experience of the in-vehicle entertainment system and navigation system. In modern cars, these systems are often highly integrated and very sensitive to the external electromagnetic environment. The double-sided lamination structural design can effectively reduce signal interference, ensure the clarity of sound quality and the accuracy of navigation, especially in densely signaled areas in cities and on highways. The superiority of this design is more obvious, improving the comfort and safety of the driver.

[0050] Optionally, the first shell 10 and the second shell 20 protect the circuit board 40 to prevent damage to the circuit board 40 by the external environment, such as dust, water vapor, etc. The first shell 10 and the second shell 20 can fix the circuit board 40 in a specific position to prevent the circuit board 40 from moving or shaking during use, which would affect the normal operation of the device.

[0051] Specifically, the conductive adhesive 41 is located outside the circuit board 40 , so that the conductive adhesive 41 , the first shell 10 , and the second shell 20 form an electromagnetic shielding cavity, and the circuit board 40 is located in the electromagnetic shielding cavity.

[0052] The use of conductive glue not only provides good electromagnetic shielding, but also has a certain thermal conductivity, which can help the circuit board dissipate heat and extend its service life. This design is particularly suitable for vehicle operation in high temperature environments, such as vehicles used in hot areas, ensuring the stable operation of the controller in harsh environments.

[0053] The application of conductive adhesive not only enhances the electromagnetic shielding effect, but also improves the thermal management capability of the system. In high temperature environments, such as vehicles used in hot areas, this design can effectively prevent circuit boards from overheating and protect sensitive electronic components from damage. This is critical to maintaining stable operation of the controller under extreme conditions, especially in electric vehicles, where thermal management of high-power electronic devices is directly related to battery life and vehicle performance. In addition, good electromagnetic shielding can also reduce interference between electronic devices and improve the overall electronic system performance of the vehicle, especially in autonomous driving vehicles with dense electronic devices. This optimization is of great significance for achieving a smooth autonomous driving experience.

[0054] Optionally, the process of forming the electromagnetic shielding cavity by the conductive adhesive 41, the first shell 10 and the second shell 20 is as follows:

[0055] S1. First, apply the conductive adhesive 41 to the installation gap 31 formed between the second housing 20 and the supporting boss 11. The conductive adhesive is generally a gel-like substance with conductive properties, which can effectively conduct electricity and form a shielding effect.

[0056] S2 . Then, assemble the first housing 10 and the second housing 20 together so that the surface coated with the conductive adhesive 41 is attached to the second housing 20 .

[0057] S3. When the first shell 10 and the second shell 20 are assembled together, the conductive glue 41 at the installation gap 31 formed between the second shell 20 and the supporting boss 11 forms a closed layer to isolate electromagnetic waves from the internal space. In this way, an electromagnetic shielding cavity is formed, which can effectively block electromagnetic interference and leakage between the inside and the outside, and protect the internal electronic equipment from the influence of external electromagnetic interference.

[0058] Specifically, at least one connecting stud 13 is provided on the first housing 10, a through hole is provided on the circuit board 40 at a position corresponding to the connecting stud 13, and at least one connecting screw 21 is provided on the second housing 20, and the connecting stud 13 is provided corresponding to the connecting screw 21, wherein the connecting screw 21 passes through the corresponding through hole and is connected to the corresponding connecting stud 13. That is, the first housing 10, the circuit board 40, and the second housing 20 are fixed to the connecting stud 13 of the first housing 10 by the connecting screw 21. The screw-bolt connection has a high bearing capacity and can withstand large tensile and shear forces; the screw-bolt connection has good anti-loosening properties and can ensure the stability of the connection. In this embodiment, the connecting screw 21 is connected to the connecting stud 13 to ensure the stability of the connection among the first housing 10, the circuit board 40, and the second housing 20.

[0059] Through the cooperation of the connecting studs and the connecting screws, the housing and the circuit board are firmly connected, and it is easy to disassemble and assemble, which improves production efficiency and maintenance convenience. This structure is suitable for large-scale production, can be assembled quickly, and reduces production costs.

[0060] The use of connecting studs and screws not only ensures a secure connection between the circuit board and the housing, but also allows for easy disassembly for maintenance or upgrades, greatly facilitating after-sales support. This quick disassembly and assembly design is particularly advantageous in mass production, which can significantly improve production efficiency and reduce production costs, while also reducing product defects caused by improper assembly. In the automotive manufacturing industry, this design is particularly suitable for assembly line assembly, which can achieve high-speed, large-volume production while ensuring product quality, meeting the growing demand for vehicles in the global market.

[0061] Specifically, there are multiple connecting studs 13, some of which are distributed at the top corners of the first shell 10, and the other connecting studs 13 are arranged in the middle of the first shell 10. In this embodiment, there are five connecting studs 13, which are distributed at the four corners and the middle of the inner cavity of the upper shell.

[0062] Optionally, the bottom of the connecting stud 13 is a regular hexagon, and the connecting stud 13 and the first shell 10 are connected by a riveting process. This connection form can fully ensure the torsional strength of the connecting stud 13 and the first shell 10.

[0063] Optionally, the specific steps of connecting the connecting stud 13 and the first housing 10 by riveting are as follows:

[0064] S1. First, determine the position and number of the connecting studs 13 and pass the connecting studs 13 through the first shell 10.

[0065] S2. Use a riveting tool to press a rivet or rivet post into the regular hexagon at the bottom of the connecting stud 13 at the position where the connecting stud 13 contacts the first housing 10 .

[0066] S3. Apply a certain pressure through a riveting tool so that the rivet or rivet stud and the connecting stud 13 are tightly connected to the first shell 10.

[0067] S4. Ensure that the riveted joints are firm and reliable, without any looseness or looseness.

[0068] It should be noted that the through hole provided on the circuit board 40 corresponds to the size and position of the connecting stud 13, and the top of the connecting stud 13 is a stepped threaded hole with a certain depth in the middle, which is connected to the corresponding through hole of the circuit board 40, thereby playing a role in supporting and fixing the circuit board 40. The stepped threaded hole with a certain depth in the middle of the top of the connecting stud 13 can make the connecting stud 13 easier to install and remove, improve work efficiency, and the stepped threaded hole can effectively prevent the threaded connection from loosening or falling off when vibrating or stressed, and play a good fixing role for the circuit board 40.

[0069] Specifically, along the thickness direction of the first shell 10, the heights of the supporting bosses 11 are arranged flush, the heights of the connecting studs 13 are arranged flush, and the heights of the supporting bosses 11 and the connecting studs 13 are arranged flush. Because one side surface in the thickness direction of the circuit board 40 fits with the supporting bosses 11, and the top of the connecting studs 13 is connected to the through-holes corresponding to the circuit board 40, the heights of the supporting bosses 11 and the connecting studs 13 are arranged flush to ensure good coplanarity. When the first shell 10, the circuit board 40, and the second shell 20 are fixed by the connecting screws 21 and the connecting studs 13, the fitting area of ​​the supporting bosses 11 and the circuit board 40 can be made sufficiently large, so that the conductive glue 41 at the installation gap 31 formed between the second shell 20 and the supporting bosses 11 can be firmly adhered to the installation gap 31, so as to improve the electromagnetic shielding of the controller as a whole.

[0070] This highly flush design ensures uniform distribution of the space inside the housing, reduces stress concentration caused by height differences, and improves the structural strength and stability of the entire controller. It is suitable for vehicle applications that need to withstand large mechanical shocks, such as off-road vehicles, racing cars, etc., ensuring the reliable operation of the controller under extreme conditions.

[0071] The highly flush design of the support boss and the connection studs effectively disperses the stress caused by mechanical shock and vibration by eliminating the height difference inside the shell, significantly improving the structural strength and long-term stability of the controller. This design is particularly important in off-road vehicles and racing cars, which experience extreme mechanical shock and vibration when driving on complex terrain or at high speeds. The highly flush support structure ensures that the controller can maintain its normal operation even under the worst conditions, avoiding system failures caused by mechanical damage and improving the reliability and safety of the vehicle in extreme environments.

[0072] Specifically, Figure 4 At least one of the first housing 10 and the second housing 20 is a stamped part. In this embodiment, the first housing 10 and the second housing 20 are both stamped and riveted to replace the original die-casting process, and the generated housing wall thickness is uniform, and the wall thickness can be reduced by 25% to 33%, thereby achieving the purpose of reducing product weight and achieving lightweight.

[0073] This design is particularly suitable for mass production and can quickly produce high-quality controller housings that are suitable for various types of vehicles, such as passenger cars, commercial vehicles, special vehicles, etc., ensuring the versatility and reliability of the controller on different vehicles.

[0074] The use of stamping technology to produce the housing not only significantly reduces material and production costs, but also ensures the consistency and assembly quality of the controller housing with its high precision and mass production capabilities. This design is especially important in mass production, which can quickly respond to market demand and produce a large number of standard-compliant housings. In passenger cars, commercial vehicles and special vehicles, the versatility and reliability of the controller are guaranteed, and consistent performance and user experience can be obtained regardless of the vehicle type. Especially for special vehicles such as military vehicles and rescue vehicles, high-precision housing manufacturing can better adapt to the special needs of these vehicles for electronic equipment and improve the reliability of the vehicle when performing tasks.

[0075] Optionally, stamping the first shell 10 and the second shell 20 can ensure the dimensional accuracy and consistency of the product and ensure stable product quality. The shell stamping process has a highly automated production process, which reduces labor costs and production costs and can greatly reduce assembly costs.

[0076] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0077] 1. The first shell and the second shell of the controller are formed by stamping process, which not only reduces the overall weight of the controller, but also reduces the cost.

[0078] 2. The first housing is connected to the connecting stud by a riveting process, and the connecting stud is tightly connected to the first housing. The riveting process connection does not require additional nuts and bolts, which can reduce the volume of the connecting parts and reduce the weight of the controller.

[0079] 3. An electromagnetic shielding cavity is formed by the conductive adhesive, the first shell, and the second shell to block internal and external electromagnetic interference and improve the electromagnetic shielding performance of the whole machine. The design method of the coplanarity of the supporting boss and the connecting stud set in the first shell allows the conductive adhesive to adhere firmly to the installation gap, thereby better improving the overall electromagnetic shielding performance of the controller.

[0080] According to another aspect of the present invention, a vehicle is provided, comprising a controller, wherein the controller is the controller in the above embodiment.

[0081] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.
