Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and specifically provides a housing assembly, a controller and a vehicle. Background Art

[0002] The controller on the vehicle is the core component for realizing the intelligence of the vehicle, responsible for integrating sensor data and executing complex control algorithms. With the continuous upgrading of automotive electronic systems, the functions of the controller have become more and more complex, resulting in the gradual increase in the electromagnetic wave intensity of the controller chip, and therefore the requirements for electromagnetic shielding performance have also increased accordingly.

[0003] In related technologies, in order to improve the heat dissipation performance of the controller, brazing technology is usually used to connect the stamped water-cooled plate and the die-cast middle frame, thereby optimizing the heat dissipation effect of the controller housing. Specifically, a structural adhesive is usually set between the stamped water-cooled plate and the die-cast middle frame to achieve a stable connection between the two. The tiny particles in the structural adhesive will leave a tiny gap between the stamped water-cooled plate and the die-cast middle frame. Due to the non-conductivity of the structural adhesive, these tiny gaps will affect the electromagnetic shielding function of the housing, reduce the housing's shielding ability against external electromagnetic interference, and thus affect the performance of the power module inside the controller.

[0004] In view of this, a new technical solution is needed in this field to solve the above problems. Summary of the invention

[0030] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not used to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

This is only for the convenience of description, and does not indicate or imply that the relevant devices or components must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application. In addition, the ordinal numbers "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] The controller on the vehicle is the core component for realizing the intelligence of the vehicle, responsible for integrating sensor data and executing complex control algorithms. With the continuous upgrading of automotive electronic systems, the functions of the controller have become more and more complex, resulting in the gradual increase in the electromagnetic wave intensity of the controller chip, and therefore the requirements for electromagnetic shielding performance have also increased accordingly.

[0034] In order to improve the heat dissipation function of the controller, the stamped water-cooling plate and the die-casting middle frame are usually connected by brazing technology, and structural adhesive is set between the two to stabilize the connection. There are tiny particles in the structural adhesive, which will cause gaps between the stamped water-cooling plate and the die-casting middle frame. Since the structural adhesive is generally a non-conductive material, the existence of these gaps will affect the electromagnetic shielding function of the shell.

[0035] For example, power modules such as circuit boards and electronic components inside the controller generate electromagnetic noise signals, which may radiate to the outside through tiny gaps in the housing. At the same time, external electromagnetic noise may also enter the controller through these gaps. This two-way electromagnetic interference may cause distortion or interference of power module signals, affecting its normal operation, thereby reducing the performance and reliability of the power module. Ultimately, this interference may affect the function and stability of the entire controller and cause instability or failure of the vehicle's electronic system.

[0036] Therefore, please refer to Figure 1-3 , is a shell component according to an embodiment of the present application, which can be applied to the above-mentioned controller 2 and solve the problem of poor electromagnetic shielding performance of the controller 2.

[0037] Specifically, refer to Figure 1The housing assembly includes a first housing 11 and a second housing 12 connected to the first housing 11. The first housing 11 and the second housing 12 are fastened together to form a receiving cavity, which is used to receive power modules such as circuit boards and electronic components.

[0038] Furthermore, the first shell 11 and the second shell 12 are both made of conductive materials, which can not only improve the overall strength of the shell assembly, but more importantly, can enhance the electromagnetic shielding performance of the entire shell assembly.

[0039] Furthermore, the first shell 11 and the second shell 12 are insulated from each other.

[0040] In an achievable manner, the first shell 11 and the second shell 12 are connected using an insulating adhesive 14. Specifically, the insulating adhesive 14, such as structural adhesive, can be coated around the first shell 11, and then the second shell 12 is snapped onto the first shell 11. The insulating adhesive 14 can enhance the connection stability between the first shell 11 and the second shell 12.

[0041] Furthermore, the housing assembly also includes a connector 13 made of a conductive material, one end of the connector 13 is connected to the first housing 11 , and the other end is connected to the second housing 12 , so that electrical conduction between the first housing 11 and the second housing 12 can be achieved.

[0042] Furthermore, a grounding terminal is provided on the first shell 11, and the entire shell assembly can be effectively grounded through the grounding terminal, which can improve the electromagnetic shielding performance of the entire shell assembly, and further enhance the electromagnetic compatibility and anti-interference ability of the entire shell assembly.

[0043] Specifically, when the shell assembly is grounded, the grounding terminal connects the shell assembly to the ground potential, forming a low-impedance path, so that the electromagnetic interference signal can be quickly and effectively introduced into the ground, thereby reducing the interference of the electromagnetic signal to the power modules such as the circuit boards and electronic components inside the shell assembly, thereby improving the electromagnetic shielding capability of the entire shell assembly and ensuring the stable operation of the controller 2 in a complex electromagnetic environment.

[0044] In an achievable implementation, the connector 13 may be a conductive gasket disposed between the first housing 11 and the second housing 12 , and the material of the conductive gasket may be a conductive metal such as copper or aluminum.

[0045] In another feasible implementation, the connector 13 may be a conductive adhesive, such as a coating or a colloid material with a conductive function, which is disposed between the first housing 11 and the second housing 12 and coated on the contacting surfaces of the two.

[0046] In the present application, the specific form of the connecting member 13 is not limited, as long as the electrical conduction between the first shell 11 and the second shell 12 can be achieved.

[0047] In one embodiment, reference Figure 3 The connecting member 13 includes a first side wall 131 and a second side wall 132 that are oppositely arranged, and a third side wall 133 connected between the first side wall 131 and the second side wall 132, and the first side wall 131 and the second side wall 132 are located on the same side of the third side wall 133, so that the first side wall 131, the second side wall 132 and the third side wall 133 form a clamp-like structure, and the three side walls enclose a clamping space.

[0048] The first shell 11 and the second shell 12 are partially embedded in the clamping space.

[0049] Specifically, refer to Figure 1 and 2 The connecting member 13 is disposed outside the first shell 11 and the second shell 12 , and is clamped at the edge of the connection between the first shell 11 and the second shell 12 through the clamping space.

[0050] The first side wall 131 and the second side wall 132 are equivalent to two side walls of the clip. The first side wall 131 is connected to the first shell 11 , the second side wall 132 is connected to the second shell 12 , and a conductive connection is achieved through the third side wall 133 .

[0051] Of course, there may be many ways to connect the first side wall 131 to the first shell 11 and the second side wall 132 to the second shell 12 , which are described in detail as follows.

[0052] In one feasible embodiment, the connector 13 is an elastic component. The connector 13 can be clamped at the edge of the connection between the first shell 11 and the second shell 12 by the clamping force generated by its elastic deformation, so that the first side wall 131 is tightly fitted with the outer surface of the first shell 11, and the second side wall 132 is tightly fitted with the outer surface of the second shell 12. This method of connecting the connector 13 to the first shell 11 and the second shell 12 through elastic pressure is simple to operate, and the connection is tight and stable, which can ensure good electrical contact between the shell and the connector 13.

[0053] In a feasible implementation, the connector 13 can bond the first side wall 131 to the first shell 11 , and the second side wall 132 to the second shell 12 by means of a conductive adhesive.

[0054] In a feasible implementation, the connecting member 13 can be connected to the first shell 11 and the second shell 12 in a snap-fitting manner through a mechanical structure, such as by providing matching snap-fit ​​grooves or snap-fit ​​protrusions on the first side wall 131, the second side wall 132 and the first shell 11, the second shell 12, so as to realize the connection between the first side wall 131 and the first shell 11, and the second side wall 132 and the second shell 12.

[0055] In a feasible implementation, the connector 13 can also achieve the connection between the first side wall 131 and the first shell 11, and the second side wall 132 and the second shell 12 by using fasteners with conductive functions (such as screws, nuts, etc.). The conductive fasteners can ensure the conductivity of the electrical connection while providing mechanical stability.

[0056] It can be seen from the above multiple connection schemes that the connection process can be effectively simplified by arranging the connection member 13 on the outside of the first shell 11 and the second shell 12 and designing it into a clip-like structure. This clip-type structure can achieve a stable connection between the connection member 13 and the first shell 11 and the second shell 12 by clamping, bonding, mechanical structure or conductive fasteners.

[0057] This design not only optimizes the connection method, but also improves the stability of the mechanical connection between the connector 13 and the first shell 11 and the second shell 12, thereby ensuring good electrical contact between the three and enhancing the electromagnetic shielding effect of the overall shell assembly.

[0058] In a preferred embodiment, the connecting member 13 is designed as an elastic member. When the first shell 11 and the second shell 12 are embedded in the clamping space, the first side wall 131 of the elastic connecting member 13 will exert a clamping force on the first shell 11 through its elastic deformation, and the second side wall 132 will also produce elastic deformation to exert a clamping force on the second shell 12.

[0059] This elastic design ensures that the first shell 11 and the second shell 12 can be firmly fixed in the clamping space, while also being able to adapt to slight size changes of the shells, thereby providing a continuous and stable clamping force, providing a stable mechanical connection and good electrical conductivity between the connector 13 and the first shell 11 and the second shell 12.

[0060] Furthermore, the distance between the first side wall 131 and the second side wall 132 is smaller than the dimension in the thickness direction after the first shell 11 and the second shell 12 are snap-fitted together. This helps the first side wall 131 to apply a clamping force to the first shell 11, and the second side wall 132 to the second shell 12, so that the first side wall 131 and the first shell 11, as well as the second side wall 132 and the second shell 12, can fit more closely.

[0061] In one embodiment, a first groove 110 is disposed on an outer surface of the first shell 11 , and a first boss 1310 is disposed on a surface of the first side wall 131 facing the clamping space. The first boss 1310 is snap-fitted into the first groove 110 .

[0062] Specifically, refer to Figure 2 Since the first side wall 131 of the connecting member 13 is elastic, when the first boss 1310 is inserted into the first groove 110, the elastic deformation helps to adjust the gap between the first boss 1310 and the surface of the first shell 11, so that the first boss 1310 can smoothly pass through the edge of the first groove 110 and be stuck in the first groove 110 under the action of elastic force.

[0063] The clamping structure of the boss and the groove not only helps to achieve accurate positioning between the first side wall 131 and the first shell 11, but also effectively prevents relative movement between the two, so that a more stable connection is formed between them.

[0064] Further, refer to Figure 3 The specific shape of the first boss 1310 is a long strip-shaped rib protruding from the surface of the first side wall 131 and extending along the surface of the first side wall 131 , and the shape of the first groove 110 matches the rib.

[0065] The structure of the convex rib can increase the contact area with the groove to generate more friction, so that the first side wall 131 is stably fixed on the first shell 11 and the displacement or looseness of the connecting member 13 caused by external vibration or impact is reduced.

[0066] In one embodiment, similar to the connection structure between the first side wall 131 and the first shell 11 , a second groove 120 is provided on the second shell 12 , and a second boss 1320 is provided on the second side wall 132 . The second boss 1320 is snap-fitted into the second groove 120 .

[0067] Similarly, the snap-fitting structure of the boss and the groove not only helps to achieve precise positioning between the second side wall 132 and the second shell 12, but also effectively prevents relative movement between the two, thereby forming a more stable connection between them.

[0068] Furthermore, the second boss 1320 is similar in shape to the first boss 1310 , and the second groove 120 is similar in shape to the first groove 110 , which will not be described in detail herein.

[0069] In summary, on the connector 13 provided in this embodiment, bosses are provided on the first side wall 131 and the second side wall 132, and grooves matching the bosses are provided on the first shell 11 and the second shell 12. This design can not only simplify the assembly process, making the assembly more intuitive and convenient, thereby saving time and cost, but more importantly, it can improve the stability of the connection, ensure the precise docking between the connector 13 and the shell, and then ensure the electrical conduction between the first shell 11 and the second shell 12, and improve the electromagnetic shielding performance of the shell assembly.

[0070] In one implementation, the first shell 11 and the first side wall 131 , as well as the second shell 12 and the second side wall 132 , may be stably connected by means of a structure in which a protruding column and a through hole cooperate (not shown in the figure).

[0071] Specifically, a protruding column is provided on the first shell 11, and a through hole cooperating with the protruding column is provided on the first side wall 131. Based on the elastic performance of the first side wall 131, the first side wall 131 can be inserted into the protruding column through the through hole thereon to achieve a stable connection with the first shell 11.

[0072] Similarly, a protruding column is also provided on the second shell 12, and a through hole cooperating with the protruding column is provided on the second side wall 132. Based on the elastic properties of the second side wall 132, the second side wall 132 can be inserted into the protruding column through the through hole thereon to achieve a stable connection with the second shell 12.

[0073] In one implementation, the third side wall 133 is connected to the first shell 11 and the second shell 12 in a flexible manner, that is, the third side wall 133 can be connected to the first shell 11, or to the second shell 12, or to both the first shell 11 and the second shell 12.

[0074] The third side wall 133 is connected to the first shell 11 , connected to the second shell 12 , or doubly connected to the first shell 11 and the second shell 12 , depending on the specific design and connection structure of the first shell 11 and the second shell 12 .

[0075] Specifically, Figure 2 Taking the structure shown as an example, when the first shell 11 adopts a concave structure, the second shell 12 will be embedded in the concave cavity of the first shell 11 when it is snap-fitted with the first shell 11. In this case, the third side wall 133 can only be fitted and connected with the side surface of the edge of the first shell 11.

[0076] In another case, when the first shell 11 and the second shell 12 are snap-fitted, their edges are aligned. In this aligned state, the third side wall 133 can be simultaneously fitted and connected with the edge side surfaces of the first shell 11 and the second shell 12.

[0077] The fitting connection design of the third side wall 133 and the edge of the shell helps to provide additional support for the first shell 11 and the second shell 12. The structural design that the three side walls of the connector 13 are simultaneously in contact with the shell helps to increase the contact surface between the connector 13 and the shell, thereby ensuring electrical conduction between the first shell 11 and the second shell 12 and improving the shielding performance of the shell assembly.

[0078] by Figure 2 Taking the structure of the first shell 11 and the second shell 12 shown in the figure as an example, in a preferred embodiment, the third side wall 133 has a third boss 1330 protruding toward the clamping space, and the third boss 1330 is tightly pressed against the first shell 11.

[0079] Specifically, refer to Figure 3 The third boss 1330 is an arc-shaped rib disposed on the third side wall 133. The rib protrudes into the clamping space and forms a certain gap with the side wall. The arc-shaped rib is separated from the third side wall 133 to form an independent support structure.

[0080] Furthermore, the convex surface of the arc-shaped rib abuts against the first shell 11. Since the arc-shaped rib itself has a certain elasticity and there is a gap between the arc-shaped rib and the third side wall 133, the arc-shaped rib can fit more closely when in contact with the first shell 11, and at the same time, a certain margin can be maintained under the action of elasticity, so that the arc-shaped rib can adapt to small displacement changes, thereby providing a better support effect.

[0081] It can be seen that the design of the arc-shaped ribs on the third side wall 133 can further improve the stability of the connection between the connecting member 13 and the first shell 11 and the second shell 12, thereby improving the performance of electrical conduction between the first shell 11 and the second shell 12 to ensure the electromagnetic shielding effect of the shell assembly.

[0082] The present application embodiment provides a controller 2, referring to Figure 1 The housing of the controller 2 adopts the housing assembly mentioned above. Specifically, the housing of the controller 2 is formed by snapping together a first housing 11 and a second housing 12 to form a housing cavity for accommodating internal components. In this housing cavity, power modules such as circuit boards and electronic components are arranged.

[0083] Through this shell component design, the electromagnetic shielding capability of the controller 2 can be enhanced, thereby effectively reducing the impact of external electromagnetic interference on the internal circuit, reducing the risk of misoperation and signal noise, and improving the signal integrity and data transmission stability of the device.

[0084] In addition, the improved shielding effect can also prevent internal electronic components from generating electromagnetic interference to the external environment, ensuring the normal operation of the equipment in various electromagnetic environments.

[0085] The embodiment of the present application also provides a vehicle, which is equipped with the above-mentioned optimized controller 2. The vehicle using such a controller 2 has significant advantages.

[0086] First, the improved housing assembly used in controller 2 greatly enhances the electromagnetic shielding effect and effectively reduces the impact of external electromagnetic interference on the internal electronic system. This not only improves the stability of the vehicle's electronic system, but also ensures the efficient operation of various sensors and control modules.

[0087] Secondly, enhanced electromagnetic shielding can reduce signal noise and improve the reliability of data transmission, thereby improving the speed and accuracy of the vehicle's intelligent system response. These improvements not only optimize the overall performance of the vehicle, but also enhance safety and driving experience.

[0088] In addition, the stability and anti-interference ability of the controller 2 can reduce maintenance costs and improve the long-term reliability of the vehicle. These advantages make vehicles equipped with this controller 2 more competitive in the market and can meet the needs of modern consumers for high-performance and high-reliability vehicles.

[0089] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
