[0030] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0031] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0032] As users' demands for smart cars continue to increase, vehicle control systems are becoming more and more complex, gradually evolving from traditional distributed architectures to domain-centralized architectures, and the decentralized controllers are divided according to functional domains and integrated into domain controllers with stronger computing power. As the core component, the domain controller divides and integrates the originally decentralized electronic control units (ECUs) according to functions or regions, so that functions that originally required multiple ECUs to complete are integrated into one domain for centralized control, which helps control bus length, reduce the weight of electronic components, and reduce vehicle manufacturing costs. It can also provide stronger computing power and lower manufacturing costs, and realize intelligent control and management of vehicles.

[0033] However, the existing domain controllers are affected by the vehicle design concept or regional division, and the installation methods of domain controllers between different models vary greatly. Some models are divided into different functional domains according to their functions, such as cockpit domain, autonomous driving domain, body domain, power domain and chassis domain; other models are divided into multiple spatial domains according to specific physical boundaries, for example, including front body domain controller, left body domain controller and right body domain controller. The types of domain controllers between different models are different, and the domain controllers are not compatible. Each platform needs to develop a domain controller that is compatible with the model separately, which leads to many styles of domain controllers, long vehicle development cycle, high R&D cost and low production efficiency.

[0034] In order to solve the above problems, the present application provides a fixed structure, a domain controller and a vehicle with flexible and convenient installation methods. In order to better understand the present application, on the one hand, the following is combined with Figures 1 to 7 According to the embodiments of the present application, the fixed structure, the domain controller and the vehicle are described in detail.

[0035] Figure 1 An overall schematic diagram of a fixing structure provided for some embodiments of the present application. Figure 2 An overall schematic diagram of another fixing structure provided for some embodiments of the present application. Figure 3 An overall schematic diagram of another fixing structure provided for some embodiments of the present application. Figure 4 An overall schematic diagram of another fixing structure provided for some embodiments of the present application. Figure 5 An overall schematic diagram of another fixing structure provided for some embodiments of the present application.

[0036] like Figures 1 to 5 As shown, an embodiment of the present application provides a fixing structure, including multiple fixing members 1 and connecting members 2, the fixing member 1 includes a first plate 11 and a second plate 12, the first plate 11 has a first surface 111 and a second surface 112 relative to each other in its own thickness direction, the second plate 12 is arranged on the first surface 111 and is bent relative to the first plate 11, the first plate 11 is used to connect to the first fixed member, and the second plate 12 is used to connect to the second fixed member; the connecting members 2 are connected to different fixing members 1 so that the multiple fixing members 1 are fixed to each other and are arranged at intervals on the outer peripheral side of the second fixed member; wherein the first surfaces 111 of different first plates 11 are located in the same plane.

[0037] The first plate 11 is used to connect with the first fixed part, and the first fixed part can be connected to multiple positions of the first plate 11. Optionally, the first fixed part is connected to the first surface 111 of the first plate 11, or the first fixed part is connected to the second surface 112 of the first plate 11. Similarly, the second plate 12 is used to connect with the second fixed part, and the second fixed part can be connected to any one of the two opposite surfaces of the second plate 12 in its own thickness direction. Exemplarily, the first fixed part is connected to the second surface 112 of the first plate 11, and the second fixed part is connected to a surface of the second plate 12 away from the first plate 11 in its own thickness direction, so as to reduce the probability of interference between the first fixed part and the second fixed part.

[0038] The first plate 11 is provided with a first connection structure connected to the first fixed member, and the first connection structure has various forms. Optionally, the first connection structure includes fasteners such as screws, which pass through the first plate 11 and the first fixed member in sequence to achieve connection; or, the first plate 11 is welded to the first fixed member. For example, Figure 1 and Figure 3 As shown, a mounting hole 113 is provided on the first plate 11, the first fixed part abuts against the surface of one side of the first plate 11, and the connecting member 2 passes through the mounting hole 113 from the side of the first plate 11 away from the first fixed part to connect the first plate 11 and the first fixed part. Similarly, a second connecting structure connected to the second fixed part is provided on the second plate 12, and the second connecting structure has a variety of forms. Optionally, the second connecting structure includes a slot structure 121 or a buckle structure 3111; or, the second plate 12 is pasted or welded to the second fixed part. It should be noted that the number of the first connecting structure or the second connecting structure can be set according to the connection requirements. Under certain conditions, the number of the first connecting structure and the second connecting structure is proportional to the connection strength between the first fixed part and the second fixed part.

[0039] The second plate 12 is disposed on the first surface 111 and is bent relative to the first plate 11. There are multiple bending angles between the second plate 12 and the first plate 11 to suit different usage scenarios. For example, at least one of the first fixed member and the second fixed member includes an inclined surface, or the first fixed member and the second fixed member are connected at a certain angle. The specific bending angle between the first plate 11 and the second plate 12 can be determined according to the shape and position of the first fixed member and the second fixed member to ensure that the shape of the fixing member 1 fits the shape of the first fixed member and the second fixed member and the connection is firm. Preferably, the second plate 12 is perpendicular to the first plate 11 to improve the structural stability of the fixing member 1 and also expand the scope of application of the fixing structure.

[0040] The connector 2 is connected to different fixing members 1 so that the multiple fixing members 1 are fixed to each other and are arranged at intervals on the outer peripheral side of the second fixed member. The connector 2 is used to connect multiple scattered fixing members 1 so that the multiple fixing members 1 are used together to connect the first fixed member and the second fixed member. The connector 2 can be connected to multiple positions of the fixing member 1, as long as the first surface 111 of the first plate 11 after connection is located in the same plane. Optionally, the connector 2 is connected to the first plate 11, or the connector 2 is connected to the second plate 12. Among them, when the connector 2 is connected to the first plate 11, the second plate 12 is connected to the second fixed member, which helps to reduce the interference between the connector 2 and the second fixing member 1 and improve the reliability of the connection. By providing multiple fixing members 1 and arranging the fixing members 1 at intervals on the outer peripheral side of the second fixed member, the connection strength and connection stability between the first fixed member and the second fixed member can be improved.

[0041] And according to different actual needs, the fixing member 1 and the connecting member 2 may be made of the same material and be an integrated structure, or they may be made of different materials and prepared separately, and then connected and fixed by welding or the like. Figure 1-Figure 5 2 shows the situation in which the fixing member 1 and the connecting member 2 are an integrated structure in different embodiments, and the junction between the fixing member 1 and the connecting member 2 is indicated by a dotted line.

[0042] The first surfaces 111 of different first plates 11 are located on the same plane, and the orientations of the multiple first surfaces 111 in the thickness direction of the first plate 11 itself can be the same or different. Optionally, the second plates 12 face the same side in the thickness direction of the first plate 11. In this case, the lower surface of the fixing structure can be made flat, which helps to improve the reliability of the connection between the fixing structure and the first fixed part. Alternatively, the second plates 12 are located on different sides in the thickness direction of the first plate 11. The fixing part 1 of this structure is suitable for the situation where the first fixed part is connected to multiple second fixed parts located on different sides of the first fixed part.

[0043] It should be noted that the first fixed member and the second fixed member mentioned above can be objects or structures that need to be connected to each other, or planes such as the ground and walls. The fixed structure is not only suitable for connecting the domain controller body 3 and the vehicle, but any two objects or planes that need to be connected can be connected using the fixed structure.

[0044] Taking the field of vehicle technology as an example, combined with Figure 6For example, the first fixed part includes the vehicle body, and also includes the vehicle's chassis, front cabin and any other objects, structures and planes that fix the domain controller body 3. The second fixed part includes the domain controller body 3. The first plate 11 is connected to the vehicle body, and the second plate 12 is connected to the domain controller body 3, thereby connecting the domain controller body 3 to the vehicle body and improving the connection stability between the domain controller body 3 and the vehicle body.

[0045] It should also be noted that the shapes of the first plate 11 and the second plate 12 are not specified here and can be determined according to the shapes and sizes of the first fixed member and the second fixed member.

[0046] The fixing structure has the characteristics of high compatibility, and can be adapted to the first fixed part and the second fixed part of various structures and shapes, providing a stable, reliable and firm connection for them. In addition, the connection method of the fixing structure is simple, easy to manufacture and produce, and can effectively reduce production costs and improve the connection efficiency of the first fixed part and the second fixed part.

[0047] Continue as Figures 1 to 5 As shown, in some embodiments, the connecting member 2 includes a connecting portion 21, which is connected to different first plates 11. In the thickness direction of the first plate 11, the connecting portion 21 has a third surface 211 and a fourth surface 212 relative to each other. The third surface 211 and the first surface 111 are located in the same plane, and the fourth surface 212 faces the first fixed member.

[0048] The connection part 21 is connected to different first plates 11, which can make the lower surface of the fixed structure flat, and help improve the connection stability and reliability between the fixed structure and the first fixed member. The shape of the connection part 21 is not specified here, and can be a plate-like structure, a rod-like structure, or a block-like structure. The specific situation can be determined according to the actual connection strength requirements.

[0049] In some embodiments, the connection portion 21 and the fixing member 1 can also be configured to be detachably connected, and the fixing members 1 with different structures can be replaced to meet the connection requirements of different second fixed members, thereby improving the adaptability and compatibility of the fixing structure.

[0050] like Figures 3 to 5 As shown, in some embodiments, the connector 2 further includes a main body portion 22 , and a plurality of connecting portions 21 are arranged at intervals on the outer peripheral side of the main body portion 22 .

[0051] The main body 22 is used to connect multiple dispersed connection parts 21, and the multiple connection parts 21 are arranged at intervals on the outer peripheral side of the main body 22 to surround the fixing member 1 around the second fixed member, thereby improving the firmness of the connection between the fixing member 1 and the first fixed member and the second fixed member.

[0052] Further optionally, the main body 22 is configured so that, in the thickness direction of the main body 22, the projection of the main body 22 is located within the projection of the second fixed component. In this case, the entire weight of the second fixed component is pressed on the main body 22, which can ensure the tightness of the connection between the second fixed component and the fixed structure; or, the main body 22 is configured so that, in the thickness direction of the main body 22, the projection of the second fixed component is located within the projection of the main body 22, so as to avoid contact between the second fixed component and the first fixed component.

[0053] It should be noted that, in some embodiments, multiple fixing members 1 can be connected and used together by providing a main body 22, which is convenient for carrying and replacement, or Figure 1 and Figure 2 As shown, the main body 22 is not provided, but the connecting part 21 is used to connect multiple fixing members 1, and the multiple fixing members 1 are arbitrarily placed at appropriate positions on the outer peripheral surface of the second fixed member. Compared with the main body 22, the fixing structure without the main body 22 is more flexible and has a variable position, and the position of the fixing member 1 can be changed according to needs.

[0054] Continue as Figures 3 to 5 As shown, in order to improve the connection strength between the second fixed member and the first fixed member, in some embodiments, at least part of the fixing members 1 are symmetrically distributed on both sides of the main body 22; and / or, at least part of the fixing members 1 are symmetrically arranged relative to the center of the first virtual center line; the first virtual center line is parallel to the thickness direction of the first plate 11 and passes through the geometric center of the main body 22.

[0055] The position distribution of the plurality of fixing members 1 relative to the main body 22 may be of various types. Optionally, at least some of the fixing members 1 are symmetrically distributed on both sides of the main body 22, where the two sides refer to both sides of the main body 22 in any direction, and the number of fixing members 1 located on one side of the main body 22 may be one or more. For example, Figure 3 As shown, fixing members 1 are provided on both sides of the main body 22, and the number of fixing members 1 on each side is two. The fixing members 1 provided on or on both sides of the main body 22 can limit the range of the second fixed member, and multiple fixing members 1 can also improve the connection firmness between the first fixed member and the fixed structure. Alternatively, at least part of the fixing members 1 are centrally symmetrically arranged relative to the first virtual center line, wherein the first virtual center line is parallel to the thickness direction of the first plate 11 and passes through the geometric center of the main body 22. The centrally symmetrical arrangement enables each orientation of the second fixed member to be provided with a fixing member 1 connected to the first fixed member, and the force between the first fixed member and the second fixed member is evenly distributed. It is not easy to fall off or be damaged when being pulled by external force, which can effectively improve the connection strength and ensure the stability of the connection. For example, as Figure 4As shown, the main body 22 includes multiple side edges, and a fixing member 1 is connected to each side edge of the main body 22 through a connecting portion 21. The centrally symmetrical arrangement of multiple fixing members 1 can not only ensure a stable connection and uniform force between the second fixed member and the first fixed member, but also effectively limit the range of the second fixed member.

[0056] It should be noted that the "geometric center" mentioned in the embodiment of the present application refers to: the most central position of an object, that is, the centroid position, and the geometric center of the main body 22 is the most central position of the main body 22. Furthermore, the first virtual center line refers to a virtual straight line extending in a direction perpendicular to the fifth surface 221 of the main body 22 and passing through the geometric center of the main body 22.

[0057] In addition to the above, the position of the fixing member 1 relative to the main body 22 can also be determined according to the connection requirements. Figure 5 As shown, a plurality of fixing members 1 are arranged on both sides of the main body 22 along the first direction X, and fixing members 1 are arranged on both sides of the main body 22 along the second direction Y. The first direction X intersects with the second direction Y. The fixing structure in this case is suitable for connecting two second fixed members arranged side by side along the first direction X, and the second fixed members can extend in the second reverse direction.

[0058] In some embodiments, Figures 3 to 5 As shown, the main body 22 includes a fifth surface 221 facing the second fixed component along the thickness direction of the main body 22 , and the fifth surface 221 is recessed inward to form a recess 222 for accommodating a partial structure of the second fixed component.

[0059] The fifth surface 221 is recessed inward to form a recess 222 for accommodating a partial structure of the second fixed component. The recess 222 can have various forms. Optionally, the recess 222 is a groove arranged on the fifth surface 221 and recessed in a direction away from the second fixed component. The bottom plate of the groove is located in the same plane as the first plate 11, and the bottom plate can provide support force for the second fixed component along the thickness direction of the main body 22; or, the recess 222 can be an opening opened on the fifth surface 221, and the second fixed component is confined in the space formed by the side wall of the opening and the surface of the first fixed component.

[0060] The recess 222 can have a variety of shapes. Optionally, the recess 222 matches the shape of the second fixed part, so that the side wall of the recess 222 provides a circumferential support force for the second fixed part, plays a role of limiting and protecting, further avoids the position offset between the second fixed part and the body 22, and improves the reliability of the connection; or, the recess 222 can also be set to a rectangular or circular shape for connection with a variety of second fixed parts of different shapes.

[0061] The recess 222 can prevent the second fixed member from being easily deviated during the movement, thereby improving the stability and reliability of the relative position between the second fixed member and the fixing structure.

[0062] Further, in some embodiments, the connecting portion 21 includes a first reinforcing portion 213 disposed on the third surface 211 ; and / or the main body portion 22 further includes a second reinforcing portion 223 disposed around the recess 222 .

[0063] The connecting portion 21 includes a first reinforcing portion 213 disposed on the third surface 211. The first reinforcing portion 213 may have a variety of structures. Optionally, the first reinforcing portion 213 includes reinforcing ribs connected to the first plate 11 and the second plate 12; or Figure 3 As shown, the first reinforcing portion 213 includes a reinforcing rib that protrudes or is recessed relative to the third surface 211. Compared with the provision of reinforcing ribs, the provision of reinforcing ribs is more convenient and simple, and does not require the use of additional materials, and the manufacturing cost is low. In some embodiments, the reinforcing ribs are usually manufactured using a stamping process. The first reinforcing portion 213 can be set at any position on the connecting portion 21. Optionally, the first reinforcing portion 213 is set at the junction of the connecting portion 21 and the main body 22 to improve the anti-bending performance between the connecting portion 21 and the main body 22; or, as Figure 3 As shown, the first reinforcing portion 213 is disposed at the joint of the plurality of fixing members 1 on the connecting portion 21 to improve the connection strength between the plurality of fixing members 1 .

[0064] The main body 22 further includes a second reinforcement portion 223, and the second reinforcement portion 223 can have a variety of structures. Figure 3 As shown, the second reinforcing portion 223 includes a reinforcing rib protruding or recessed relative to the fifth surface 221. In some embodiments, the reinforcing rib is usually manufactured using a stamping process; or, the second reinforcing portion 223 may also include a thickened structure provided on the fifth surface 221. The second reinforcing portion 223 may have a variety of positions, preferably, as Figure 3 As shown, the second reinforcement part 223 is arranged around the recess 222 to ensure the anti-bending and anti-twisting performance of the entire main body 22. At the same time, the second reinforcement part 223 is arranged around the recess 222 and is not easy to interfere with the recess 222, so that the main body 22 can be fully utilized.

[0065] It should be noted that the first reinforcement portion 213 and the second reinforcement portion 223 may be provided on the connection portion 21 and the main body portion 22 respectively, or only the first reinforcement portion 213 may be provided on the connection portion 21 , or only the second reinforcement portion 223 may be provided on the main body portion 22 .

[0066] And according to different actual needs, the first reinforcement part 213 and the second reinforcement part 223 can include the same material or different materials, the first reinforcement part 213 and the second reinforcement part 223 can both be convex structures, or both can also be concave structures. In addition, one of the first reinforcement part 213 and the second reinforcement part 223 can be set as a convex structure, and the other can be set as a concave structure.

[0067] The first reinforcement part 213 and the second reinforcement part 223 can improve the inherent strength and connection performance of the fixing structure, and are not easily deformed, twisted or broken under the action of external force, thereby increasing the service life of the fixing structure and ensuring the connection strength of the first fixed part and the second fixed part.

[0069] like Figure 6 to Figure 7 As shown, an embodiment of the present application further provides a domain controller, including the above-mentioned fixing structure and a second fixed member, the second fixed member includes a domain controller body 3, and the domain controller body 3 is connected to the second plate 12 of the fixing member 1.

[0070] The domain controller body 3 is connected to the second plate 12 of the fixing member 1 as the second fixed member, and there are multiple connection modes between the domain controller body 3 and the second plate 12. Optionally, the domain controller body 3 and the second plate 12 are detachably connected through the buckle structure 3111 and the slot structure 121; or, the domain controller body 3 and the second plate 12 are fixedly connected by welding.

[0071] By setting a fixed structure, the domain controller can be directly connected to different first fixed parts without considering its own structure or appearance, which effectively improves the compatibility and application scope of the domain controller.

[0072] In some embodiments, Figure 6 and Figure 7 As shown, the domain controller body 3 includes an upper shell 31 and a lower shell 33. The upper shell 31 includes an outer peripheral surface, a portion of the outer peripheral surface is recessed to form a groove structure 311, and the second plate 12 is configured to be slidably connected to the groove structure 311 along a direction parallel to the plane where the second plate 12 is located.

[0073] The domain controller body 3 includes an upper shell 31 and a lower shell 33 . The upper shell 31 and the lower shell 33 enclose a space for accommodating the circuit board assembly 32 , which is used to place and protect the circuit board assembly 32 .

[0074] The second plate 12 can be connected to multiple positions of the domain controller body 3. Preferably, the second plate 12 is connected to the upper shell 31. By connecting the second plate 12 to the upper shell 31, it is possible to provide a force for the connection between the upper shell 31 and the lower shell 33, thereby improving the tightness of the connection between the upper shell 31 and the lower shell 33, so that the upper shell 31 and the lower shell 33 are not easily separated when subjected to bumps or external forces.

[0075] The upper shell 31 includes an outer peripheral surface, and a portion of the outer peripheral surface is recessed to form a groove structure 311. The second plate 12 is configured to be slidably connected to the groove structure 311 along a direction parallel to the plane where the second plate 12 is located. There are many ways to connect the second plate 12 to the domain controller body 3. Optionally, the domain controller body 3 and the second plate 12 are detachably connected through a snap structure 3111 and a slot structure 121; or, the domain controller body 3 and the second plate 12 are fixedly connected by welding. For example, Figure 6 and Figure 7 As shown, a groove structure 311 is formed at a portion of the outer circumference of the upper shell 31, and the width of the second plate 12 matches the width of the groove structure 311, so that the second plate 12 can be slidably connected to the groove structure 311 in a direction parallel to the plane where the second plate 12 is located, so as to achieve a detachable connection between the second plate 12 and the upper shell 31. This connection method is simple and convenient, and can effectively improve the installation efficiency. At the same time, the second plate 12 is clamped in the groove structure 311, which can provide a limit for the domain controller body 3 to prevent it from being offset.

[0076] Furthermore, in order to improve the connection firmness between the second plate 12 and the upper shell 31, in some embodiments, a snap structure 3111 and a slot structure 121 are provided on the bottom surface of the groove structure 311, and the other snap structure 3111 and the slot structure 121 are provided on the second plate 12.

[0077] For example, continue as Figure 6 and Figure 7 As shown, a protruding snap-on structure 3111 is provided on the ground of the groove structure 311 on the outer peripheral surface of the upper shell 31, and a snap-on structure 121 is provided on the second plate 12. The snap-on structure 121 and the snap-on structure 3111 cooperate with each other to realize the connection between the upper shell 31, the lower shell 33, and the fixed structure, thereby ensuring the connection reliability of the three in a direction parallel to the plane where the second plate 12 is located.

[0078] Affected by the vehicle design concept or regional division, the installation methods of domain controllers between different models are quite different, and the types of domain controllers between different models are different, which leads to incompatibility of domain controllers. Each platform needs to develop a domain controller that is compatible with the model separately, which virtually prolongs the vehicle development cycle, increases R&D costs, and affects production efficiency. The domain controller body 3 can improve the compatibility of the domain controller by using the fixed structure, making it suitable for different models and different platforms.

[0079] On the other hand, an embodiment of the present application further provides a vehicle, comprising the above-mentioned domain controller and a first fixed component, wherein the first fixed component comprises a vehicle body, and the domain controller is connected to the vehicle body via a fixed structure.

[0080] The domain controller is connected to the vehicle body as the first fixed part through the above-mentioned fixing structure, wherein the vehicle body can be any location in the vehicle where the domain controller needs to be installed, such as the front cabin of the vehicle, the chassis, etc.

[0081] This fixed structure can not only ensure that the connection between the vehicle and the domain controller is firm and reliable, but also is applicable to a variety of vehicle models. Regardless of how the vehicle divides the installation position of the domain controller, the fixed structure can be used to achieve the connection between the vehicle and the domain controller, which is convenient for subsequent maintenance of the vehicle and replacement of the domain controller, and effectively improves the service life of the vehicle and the domain controller.

[0082] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
