Description

Technical Field

[0002] The VCU control unit (Vehicle Control Unit) and the ECM control unit (Engine Control Module) are the core control components of new energy vehicles. Their layout and installation methods are particularly important in the vehicle development process. The installation structure design of the vehicle core control unit generally follows the following three principles:

[0003] 1. Spatial layout: The VCU control unit and ECM control unit are mostly arranged in the front cabin area. Since the front cabin has the powertrain and the front cabin structure is the core area of ​​collision performance, the space layout is limited. It is difficult to reasonably design the installation brackets of the VCU control unit and ECM control unit.

[0004] 2. Structural strength: The installation structure should avoid loosening and falling off and structural vibration and abnormal noise. Loosening and falling off may lead to vehicle safety accidents, and structural vibration and abnormal noise may lead to reduced NVH performance of the entire vehicle.

[0005] 3. Ease of disassembly and assembly: The ease of disassembly and assembly directly affects vehicle production efficiency and vehicle after-sales maintenance costs.

[0006] The core control unit of most mainstream vehicles on the market is located in the front cabin, typically on the right side of the powertrain and in front of the right front shock absorber tower. The mounting bracket is typically bolted to the powertrain suspension, and the VCU and ECM control units are also bolted to the mounting bracket. This structural design presents the following issues:

[0007] 1. Poor spatial integration: The VCU control unit and ECM control unit are generally fixed with a mounting bracket each, resulting in poor space utilization. The front cabin is the energy-absorbing area for vehicle collision safety, housing the powertrain, air-conditioning compressor, radiator, and engine air intake system, and the space layout is very limited.

[0008] 2. Weak structural design and poor material utilization: The mounting bracket is generally a cantilever beam structure, and the strength and modality of the mounting bracket require more materials to meet the target requirements. Utility Model Content

[0039] Figure 1 This is a structural diagram of a mounting bracket 100 provided in an embodiment of the present application. Figure 2 This is an exploded schematic diagram of a mounting bracket 100 provided in an embodiment of the present application, as shown in FIG. Figure 1 and Figure 2As shown, an embodiment of the present application provides a mounting bracket 100 for mounting a vehicle's VCU control unit and ECM control unit, and is arranged in the vehicle's front cabin. The mounting bracket 100 includes a mounting bracket body 10, a vehicle body connection bracket 20, and a wiring harness mounting bracket 30.

[0040] Among them, combined Figure 3 The following diagram illustrates the structure of the mounting bracket 100 during installation. The mounting bracket body 10 is used to mount the VCU control unit 1 and the ECM control unit 2. The bottom of the mounting bracket body 10 is mounted on the powertrain mount 3 in the vehicle's front cabin. The vehicle body connection bracket 20 is connected to the top of the mounting bracket body 10 and is used to connect to the vehicle body to secure the top of the mounting bracket 100. The wiring harness mounting bracket 30 is connected to the bottom of the mounting bracket body 10 to support the wiring harnesses of the VCU control unit 1 and the ECM control unit 2. Each component is described in detail below.

[0041] Figure 4 and Figure 5 This is a schematic structural diagram of a mounting bracket body 10 at different angles provided in an embodiment of the present application, such as Figure 4 and Figure 5 As shown, the mounting bracket body 10 is an L-shaped plate-like structure, comprising a first mounting portion 11 arranged along a first direction and a second mounting portion 12 arranged along a second direction, wherein the first and second directions are perpendicular to each other. During installation and use, the first direction is the height direction of the vehicle, i.e., the first mounting portion 11 is arranged along the height direction of the vehicle, and the second direction is the width direction of the vehicle, i.e., the second mounting portion 12 is arranged along the width direction of the vehicle, and the second mounting portion 12 is located at the bottom of the first mounting portion 11. Furthermore, the figure also shows a third direction, which is perpendicular to both the first and second directions and, during installation and use, the third direction is the length direction of the vehicle.

[0042] The first mounting portion 11 has opposing first and second surfaces 111, 112. The first surface 111 is used to mount the VCU control unit 1, while the second surface 112 is used to mount the ECM control unit 2. The first mounting portion 11 is provided with a plurality of first mounting holes 113 and a plurality of second mounting holes 114. The plurality of first mounting holes 113 are used to connect to the VCU control unit 1 via fasteners, while the plurality of second mounting holes 114 are used to connect to the ECM control unit 2 via fasteners. At least one of the first mounting holes 113 and the second mounting hole 114 is located at the top of the first mounting portion 11, i.e., at the end away from the second mounting portion 12, and is also used to connect to the vehicle body connection bracket 20 via fasteners.

[0043] As an example, the first mounting portion 11 is provided with four first mounting holes 113 and three second mounting holes 114, the four first mounting holes 113 are distributed in a rectangular shape, and the three second mounting holes 114 are distributed in a triangular shape. Figure 3 and Figure 4 As shown, the first mounting hole 113 is used to connect to the VCU control unit 1 via a first bolt 40, and the second mounting hole 114 is used to connect to the ECM control unit 2 via a second bolt 50. Of the four first mounting holes 113, two are located at the top of the first mounting portion 11, one of which is located in the middle of the top and is also used to connect to the vehicle body connection bracket 20 via the first bolt 40. The other two first mounting holes 113 are located at the bottom of the first mounting portion 11.

[0044] The second mounting portion 12 is connected to the bottom of the first mounting portion 11 and is located on the side of the first surface 111. The second mounting portion 12 is used to be mounted on the powertrain mount 3. The second mounting portion 12 is provided with a plurality of third mounting holes 121, which are used to connect to the powertrain mount 3 via fasteners. At least one third mounting hole 121 is also used to connect to the wiring harness mounting bracket 30 via a fastener.

[0045] As an example, three third mounting holes 121 are provided on the second mounting portion 12, and the three third mounting holes 121 are distributed in a triangular shape. Figure 3 and Figure 4 As shown, the third mounting hole 121 is used to connect to the powertrain mount 3 via a third bolt 60. Two third mounting holes 121 are waist-shaped holes and are located at one end of the second mounting portion 12 along the third direction. These two third mounting holes 121 are also connected to the wiring harness mounting bracket 30 via the third bolt 60. The waist-shaped hole design facilitates position adjustment of the second mounting portion 12 when connected to the powertrain mount 3. The other third mounting hole 121 is located at the other end of the second mounting portion 12 along the third direction.

[0046] like Figure 4 As shown, the mounting bracket body 10 may further include a harness mounting portion 13, which is fixedly connected to the second mounting portion 12 and can be used to limit the position of the harness of the VCU control unit 1. When used together with the harness mounting bracket 30, the harness mounting portion 13 can better constrain the routing of the harness of the VCU control unit 1.

[0047] As an example, the wiring harness mounting portion 13 is in a cross shape, and both ends of the wiring harness mounting portion 13 are fixedly connected to the second mounting portion 12. A wiring harness channel arranged along a third direction is formed between the middle portion of the wiring harness mounting portion 13 and the surface of the second mounting portion 12. When installed and used, the wiring harness channel can allow the wiring harness of the VCU control unit 1 to pass through.

[0048] In order to reduce weight, the mounting bracket body 10 may be provided with weight-reducing holes 14. As an example, two weight-reducing holes 14 are provided on the first mounting portion 11.

[0049] To increase structural strength, the mounting bracket body 10 may further be provided with a first reinforcing rib 15. As an example, the first reinforcing rib 15 is provided at the junction of the first mounting portion 11 and the second mounting portion 12 to strengthen the structural strength of the bend of the mounting bracket body 10. Specifically, the first reinforcing rib 15 is a convex rib that protrudes from the second surface 112 of the mounting bracket body 10 toward the first surface 111.

[0050] like Figure 1 and Figure 2 As shown, the vehicle body connection bracket 20 is connected to the top of the first mounting portion 11 of the mounting bracket body 10 and is located on the same side of the first mounting portion 11 as the second mounting portion 12. The structure of the vehicle body connection bracket 20 is designed based on the location of the VCU control unit 1 that needs to be avoided and the location on the vehicle body to which it is connected. The vehicle body connection bracket 20 can be a one-piece or modular structure. The modular structure is easier to process separately and offers greater flexibility, facilitating adjustment and replacement of parts.

[0051] As an example, Figure 6 A structural diagram of a vehicle body connection bracket 20 provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the vehicle body connecting bracket 20 is a combined structure, including a first connecting bracket 21 and a second connecting bracket 22 .

[0052] The first connecting bracket 21 is cantilevered and has multiple bending structures. Figure 3 and Figure 6 As shown, one end of the first connecting bracket 21 is provided with a first connecting hole 211 and is connected to the top of the first mounting portion 11 via a first bolt 40. The other end of the first connecting bracket 21 is provided with a second connecting hole (not shown in the figure) and is connected to the second connecting bracket 22 via a fourth bolt 23. The first connecting bracket 21 extends downward in a first direction from one end to the other, then bends to the right in a second direction, bends downward in the first direction, bends to the right in the second direction, bends backward in a third direction, and finally extends backward in the third direction. The downward extension in the first direction is to be parallel to the first mounting portion 11, the multiple bends are to avoid the top of the VCU control unit 1, and the backward extension in the third direction is to approach the part of the vehicle body to which the vehicle body connecting bracket 20 is to be connected.

[0053] To increase structural strength, the first connecting bracket 21 may be provided with a second reinforcing rib 212 extending along its length. The second reinforcing rib 212 is a convex rib that protrudes from the lower surface to the upper surface of the first connecting bracket 21. The edge of the first connecting bracket 21 may also be folded to form a first flange 213, which can further increase structural strength, especially the continuously bent portion.

[0054] The second connecting bracket 22 is used to connect the vehicle body. The shape of the second connecting bracket 22 is designed according to the part on the vehicle body to be connected to ensure that they fit together during connection. Specifically, when installed and used, the second connecting bracket 22 is used to connect to the front shock absorber tower package 4. The upper end of the second connecting bracket 22 is bent and fits with the other end of the first connecting bracket 21. The upper end of the second connecting bracket 22 is provided with a third connecting hole (not shown in the figure), and is connected to the other end of the first connecting bracket 21 by a fourth bolt 23. The lower part of the second connecting bracket 22 has a first connecting surface 221 and a second connecting surface 222 at an angle. The first connecting surface 221 and the second connecting surface 222 are used to position, fit and weld with the side wall of the front shock absorber tower package 4. The welding positions are shown in the figure at welding points A and welding points B.

[0055] In order to increase structural strength, the edge of the second connecting bracket 22 can be folded to form a second flange 223 .

[0056] like Figure 1 and Figure 2 As shown, the wire harness mounting bracket 30 is connected to the bottom of the mounting bracket body 10 by two third bolts 60. The structure of the wire harness mounting bracket 30 is designed according to the space in the front cabin of the vehicle.

[0057] As an example, Figure 7 A schematic structural diagram of a wiring harness mounting bracket 30 provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the harness mounting bracket 30 includes a connecting portion 31 and a supporting portion 32 .

[0058] The connecting portion 31 is disposed at the bottom of the second mounting portion 12 of the mounting bracket body 10 and is connected to the second mounting portion 12. The connecting portion 31 is provided with fourth connecting holes 311 and connecting slots 312 distributed along the second direction. The fourth connecting holes 311 and connecting slots 312 are respectively connected to the two third mounting holes 121 of the second mounting portion 12 via third bolts 60. The fourth connecting holes 311 may be waist-shaped holes extending along the third direction. The design of the waist-shaped holes and connecting slots 312 facilitates adjustment of the position of the connecting portion 31 when connected to the second mounting portion 12.

[0059] The support portion 32 is located to the side of the second mounting portion 12 in the third direction. The support portion 32 is used to support the wiring harnesses of the VCU control unit 1 and the ECM control unit 2. Of course, the support portion 32 can also be used to support other wiring harnesses in the vehicle's front cabin. The support portion 32 has a first support surface 321 and a second support surface 322 arranged side by side along the second direction. The first support surface 321 extends along the third direction and is used to support the wiring harness of the VCU control unit 1. The first support surface 321 is provided with a first limiting hole 323 for limiting the position of the wiring harness of the VCU control unit 1. The second support surface 322 is inclined downward relative to the third direction and is closer to the second surface 112 of the first mounting portion 11 in the second direction than the first support surface 321. The second support surface 322 is used to support the wiring harness of the ECM control unit 2. The second support surface 322 is provided with a second limiting hole 324 for limiting the position of the wiring harness of the ECM control unit 2.

[0060] In order to increase structural strength, the edge of the support portion 32 can be folded to form a third flange 325 .

[0061] The mounting bracket 100 is placed in the front cabin of the vehicle when it is installed and used. Figure 3 As shown, combined with Figure 1 、 Figure 2 ,as well as Figures 4 to 6 The first mounting portion 11 of the mounting bracket body 10 is arranged along the height direction of the vehicle, the VCU control unit 1 is installed on the first surface 111 of the first mounting portion 11 by a first bolt 40, and the ECM control unit 2 is installed on the second surface 112 by a second bolt 50. The second mounting portion 12 is arranged at the bottom of the first mounting portion 11 and along the width direction of the vehicle, and the second mounting portion 12 is fixed to the top of the powertrain suspension 3 by a third bolt 60.

[0062] The vehicle body connection bracket 20 is connected to the top of the mounting bracket body 10 and is located on the same side of the first mounting portion 11 as the second mounting portion 12. One end of the first connection bracket 21 is connected to the top of the first mounting portion 11 via a first bolt 40, used for mounting the VCU control unit 1. The other end of the first connection bracket 21 is connected to the second connection bracket 22 via a fourth bolt 23. The second connection bracket 22 is positioned, aligned, and welded to the sidewall of the front shock absorber tower 4 via its first and second connection surfaces 221 and 222.

[0063] The wiring harness mounting bracket 30 is connected to the bottom of the mounting bracket body 10 and is positioned along the length of the vehicle. The connecting portion 31 is secured between the bottom of the second mounting portion 12 and the top of the powertrain mount 3 by two third bolts 60. The supporting portion 32 is located forward of the connecting portion 31 along the length of the vehicle. The wiring harness for the VCU control unit 1 is supported by a first supporting surface 321 and positioned within a first retaining hole 323. The wiring harness for the ECM control unit 2 is supported by a second supporting surface 322 and positioned within a second retaining hole 324.

[0064] As can be seen, this mounting bracket 100 can simultaneously mount the VCU control unit 1 and the ECM control unit 2. Furthermore, it is positioned forward of the front shock absorber tower 4 in the vehicle's length direction, avoiding encroaching on the front shock absorber's layout space. It is also positioned above the longitudinal beam 5 in the vehicle's height direction, avoiding encroaching on the longitudinal beam's layout space. Furthermore, it is positioned atop the powertrain mount 3 in the vehicle's width direction, avoiding encroaching on the powertrain's layout space. Therefore, this mounting bracket 100 improves the integration of the vehicle's front cabin interior space and enhances space utilization.

[0065] It should be noted that those skilled in the art can exchange the installation positions of the VCU control unit 1 and the ECM control unit 2 on the mounting bracket body 10 as needed, but they need to adaptively adjust the hole positions on the first mounting portion 11, and also need to adjust the multiple bending structures of the first connecting bracket 21 of the vehicle body connecting bracket 20 to avoid the top of the ECM control unit 2.

[0066] In addition, in terms of material selection of the mounting bracket 100 , the mounting bracket body 10 , the vehicle body connection bracket 20 , and the wiring harness mounting bracket 30 can all be made of cold-rolled steel plate DC01, which has excellent mechanical properties.

[0067] In terms of thickness design, the wiring harness mounting bracket 30 of the mounting bracket 100 can be thinner than the mounting bracket body 10 and the vehicle body connecting bracket 20, thereby reducing weight. For example, the wiring harness mounting bracket 30 is 1.0 mm thick, the mounting bracket body 10 is 1.5 mm thick, the first connecting bracket 21 of the vehicle body connecting bracket 20 is 1.5 mm thick, and the second connecting bracket 22 is 1.4 mm thick.

[0068] The structural performance of the mounting bracket 100 is primarily determined by its strength and modal performance. Strength ensures the mounting bracket's reliability under extreme vehicle road conditions, while modal performance ensures the mounting bracket avoids resonance with other systems under various vehicle road conditions, which could cause vibration, noise, or vibration fatigue.

[0069] As an example, the CAE finite element simulation analysis results of the strength and modal performance of the mounting bracket 100 are shown in Tables 1 and Figure 8 .

[0070] Table 1 CAE finite element analysis results of the mounting bracket strength

[0071]

[0072] According to Table 1 and Figure 8 As shown, the strength and modal performance of the mounting bracket 100 both meet the design requirements, thus proving the rationality of the structural design of the mounting bracket.

[0073] An embodiment of the present application further provides a vehicle, which includes the above-mentioned mounting bracket 100 .

[0074] In summary, the mounting bracket and vehicle provided in the embodiments of the present application can simultaneously install a VCU control unit and an ECM control unit on the mounting bracket, which can improve the degree of integration of the internal space layout of the vehicle's front cabin and improve space utilization; the body connection bracket used to connect the vehicle body adds fixed connection points to the mounting bracket, so that the mounting bracket is fixed at the upper and lower ends when arranged in the vehicle's front cabin, which can effectively improve the strength and modal performance of the mounting bracket, thereby improving material utilization and realizing a lightweight design of the structure.

[0075] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in the present application, which should all be included in the scope of protection of the present application.
