Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0041] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections, or communication; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0042] The following combination Figure 1-Figure 5 The fixing bracket 10 , the controller assembly 100 having the fixing bracket 10 , and the vehicle having the controller assembly 100 according to an embodiment of the present invention will be described in detail.

[0043] Reference Figure 1 、 Figure 3-Figure 5 As shown, the fixing bracket 10 according to the first embodiment of the present invention has a bracket fixing position 21, which can be used to install and fix the fixing bracket 10 on the vehicle. For example, in some embodiments, the bracket fixing position 21 is a bracket fixing hole, and the bolt 50 passes through the bracket fixing hole and is fastened to the corresponding component, thereby achieving the installation of the fixing bracket 10 on the component.

[0044] The fixed bracket 10 may include a bracket body 1, on which an electrical component mounting structure is provided. The electrical component mounting structure can be used to provide a mounting position for an electrical component, thereby enabling the electrical component to be installed on the fixed bracket 10. In the present invention, the controller 20 (VCU, Vehicle Control Unit) is used as an example for description.

[0045] In some embodiments of the present invention, the electrical device mounting structure may include at least two first mounting bosses 111, each of which is fixedly connected to the bracket body 1, and all of the first mounting bosses 111 are facing the first side of the bracket body 1 ( Figure 1 When installing the electrical component on the fixing bracket 10, the first mounting hole of the electrical component is directly aligned with the first mounting boss 111, and the first mounting boss 111 is directly inserted into the corresponding first mounting hole. Then, the nut 40 is tightened on the threaded section at the end of the first mounting boss 111 to complete the installation and fixation of the electrical component on the fixing bracket 10.

[0046] Optionally, the first mounting boss 111 may be fixed to the bracket body 1 by welding to form a first projection welding stud.

[0047] The fixing points of the at least two first mounting bosses 111 are located on the same first straight line L1. The angle between the first straight line L1 and the horizontal plane is 5°-20°. This allows the plug port 201 of the electrical device mounted on the first mounting boss 111 to tilt downward. This improves the waterproof performance of the plug port 201. Even if water enters the plug port 201, it will flow out of the plug port 201 due to the downward tilt of the plug port 201, preventing short circuits caused by water accumulation in the plug port 201. Optionally, the angle between the first straight line L1 and the horizontal plane can be 5°, 10°, 15°, 20°, etc.

[0048] Specifically, in Figure 1 In the specific example, there are two first mounting bosses 111, and the line connecting the fixing points of the two first mounting bosses 111 is located on the same first straight line L1. In some embodiments not shown in the figure, there may be three, four or more first mounting bosses 111.

[0049] According to the fixing bracket 10 of the embodiment of the present invention, by providing the first mounting boss 111 for mounting the electrical component, the problem of complicated installation operation when using bolts and nuts alone can be avoided. In addition, by designing the angle between the first straight line L1 where the fixing point of the first mounting boss 111 is located and the horizontal plane to be 5°-20°, the plug interface 201 of the electrical component mounted on the first mounting boss 111 can be tilted downward, thereby facilitating the improvement of the waterproof performance at the plug interface 201 of the electrical component.

[0050] In some embodiments of the present invention, reference Figure 1 、 Figure 3-Figure 5 As shown, the electrical component mounting structure may further include second mounting bosses 112. The second mounting bosses 112 are fixedly connected to the bracket body 1 and extend toward the first side of the bracket body 1. The fixing points of the second mounting bosses 112 are located below the first straight line L1. The second mounting bosses 112 can assist in mounting the electrical component. The second mounting bosses 112 can be fixed to the bracket body 1 by welding to form second projection weld studs. When installing the electrical component on the fixing bracket 10, directly align the first mounting hole of the electrical component with the first mounting boss 111, align the second mounting hole of the electrical component with the second mounting boss 112, and make the first mounting boss 111 directly pass through the corresponding first mounting hole, and the second mounting boss 112 directly pass through the corresponding second mounting hole, and then tighten the nut 40 on the end threaded section of the first mounting boss 111 and the second mounting boss 112 to complete the installation and fixation of the electrical component on the fixing bracket 10. Compared with the solution of using multiple sets of bolts and nuts and Y-axis brackets in the related art, the solution of the present invention can significantly reduce the weight while ensuring the installation strength.

[0051] In some embodiments, reference Figure 1 As shown, there are multiple second mounting bosses 112, and the fixing points of the multiple second mounting bosses 112 are distributed on the same second straight line L2, and the second straight line L2 is parallel to the first straight line L1. Figure 1 In the specific example, there are two second mounting bosses 112, and the line connecting the fixing points of the two second mounting bosses 112 is located on the same second straight line L2. In some embodiments not shown in the figure, there may be three, four or more second mounting bosses 112.

[0052] In some embodiments of the present invention, the fixing bracket 10 may further include a mounting flange 2, the mounting flange 2 being connected to the lower end of the bracket body 1, and the mounting flange 2 being disposed toward the second side ( Figure 1 The bracket 10 extends from the mounting flange 2 (side B in the figure). Bracket fixing portions 21 are provided on the mounting flange 2. Bracket fixing portions 21 are used to secure the fixing bracket 10 to the vehicle. Thus, when installing the fixing bracket 10 on the vehicle, installation can be performed on the second side of the bracket body 1; while when installing the controller 20 on the fixing bracket 10, installation can be performed on the first side of the bracket body 1. This eliminates interference between the two sides and facilitates efficient use of space.

[0053] In some embodiments of the present invention, reference Figure 1 、 Figure 3-Figure 5 As shown, one end of the bracket body 1 is provided with a collision flange 12 extending toward the first side of the bracket body 1, and the collision flange 12 is close to the higher first mounting boss 111. Specifically, the rear end of the first straight line L1 is higher and the front end is lower. For the multiple first mounting bosses 111 arranged on the first straight line L1, the first mounting boss 111 located at the rear end is higher, and the first mounting boss 111 located at the front end is lower. The collision flange 12 is located at the rear end of the bracket body 1, and the plug interface 201 of the electrical device is located at the front end of the bracket body 1. Therefore, the collision flange 12 is away from the plug interface 201 of the electrical device. In this way, the collision flange 12 will not hinder the wiring harness from being plugged in at the plug interface 201.

[0054] A weakening structure 13 is provided on the bracket body 1 at the end of the collision flange 12. The strength of the bracket body 1 near the weakening structure 13 is relatively small. When the fixed bracket 10, especially the collision flange 12, is subjected to impact force, the weakening structure 13 is prone to collapse and deformation, causing the bracket body 1 to deform.

[0055] When the collision flange 12 is one-segment, the weakening structure 13 may be located at the lower end of the collision flange 12. When the collision flange 12 is multi-segmented, the weakening structure 13 may be located between two adjacent collision flanges 12.

[0056] After the fixed bracket 10, which houses the electrical components, is installed within the front cabin of the vehicle, in the event of a collision, the collision flange 12 intrudes into the cab and is blocked by the collision blocking structure 30 within the front cabin. The weakening structure 13 at the end of the collision flange 12 collapses and deforms, causing the bracket body 1 to deform. The electrical components rotate with the bracket body 1, and the deformation of the bracket body 1 absorbs the collision energy, preventing direct damage to the electrical components from external forces, thereby protecting the electrical components from failure. This structure can also be used in conjunction with pedestrian protection. Because the electrical components and the fixed bracket 10 are installed at a high position within the front cabin, very close to the pedestrian protection area, the bracket body 1 deforms and rotates, causing the collision flange 12 to move upward. In other words, the upper surface of the fixed bracket 10 now changes from a sharp edge to a wide collision flange 12. The collision flange 12 has a certain load-bearing function, supporting pedestrians while also preventing the original sharp edge structure above the fixed bracket 10 from causing scratches on pedestrians.

[0057] In some embodiments of the present invention, the weakening structure 13 is configured as a weakening notch recessed into the bracket body 1. The strength of the bracket body 1 is weakened at the weakening notch, so when the fixed bracket 10 is subjected to an impact force, the weakening notch is prone to collapse and deformation.

[0058] In some embodiments of the present invention, the weakening structure 13 is constructed as a thickness reduction zone, and the thickness of the thickness reduction zone is thinner than the thickness of the bracket body 1. Therefore, when the fixed bracket 10 is subjected to impact force, the thickness reduction zone is prone to collapse and deformation.

[0059] In some embodiments of the present invention, a wire harness anti-cut flange 14 is provided at one end of the bracket body 1 away from the collision flange 12. Figure 1 、 Figure 3 As shown, the wire harness anti-cut flange 14 is located at the front end of the bracket body 1, the electrical components are located on the first side of the bracket body 1, and the wire harness anti-cut flange 14 extends toward the second side of the bracket body 1. In other words, the bracket body 1 is flanged at the sharp edge that can contact the wire harness to form the wire harness anti-cut flange 14, so as to ensure that the bracket body 1 has no sharp edges within a certain distance range of the wire harness, for example, the bracket body 1 has no sharp edges within 25mm of the wire harness. Figure 1 、 Figure 3-Figure 5 As shown, the plug port 201 opens toward the front of the vehicle, making it easier to plug in wires from the front of the vehicle. The wires are all routed out from the front of the bracket body 1, making them easier to manage. Furthermore, the wire harness anti-cut flange 14 is also located at the front of the bracket body 1, effectively protecting the wire harness.

[0060] During the manufacturing process of the fixed bracket 10 , the wire harness anti-cut flange 14 can be formed by bending the front edge of the bracket body 1 , or can be fixedly connected to the front edge of the bracket body 1 through a welding process.

[0061] In some embodiments of the present invention, the end of the bracket body 1 away from the collision flange 12 is recessed inward to form a wiring harness plug-in avoidance structure 15, and the wiring harness plug-in avoidance structure 15 is located below the first straight line L1. Figure 1 、 Figure 3-Figure 5 As shown, the plug port 201 opens toward the front of the vehicle, and the wiring harness plug-in avoidance structure 15 is also located at the front end of the bracket body 1. In other words, the wiring harness plug-in avoidance structure 15 and the wiring harness cut-resistant flange 14 are both located at the front end of the bracket body 1. The provision of the wiring harness plug-in avoidance structure 15 can reduce the weight of the bracket body 1. Furthermore, the wiring harness is located within the wiring harness plug-in avoidance structure 15, further utilizing the space. The wiring harness cut-resistant flange 14 can be provided at the edge of the wiring harness plug-in avoidance structure 15 to better protect the wiring harness.

[0062] In some embodiments of the present invention, the fixing bracket 10 may further include a mounting flange 2, the mounting flange 2 being connected to the lower end of the bracket body 1, and the mounting flange 2 being disposed toward the second side ( Figure 1 The bracket fixing portion 21 is provided on the mounting flange 2. The side of the mounting flange 2 away from the bracket body 1 extends along a straight line MN. The angle between the straight line MN and the bracket body 1 is 70°-85°. Optionally, the angle between the straight line MN and the bracket body 1 can be 70°, 75°, 80°, 82°, 85°, etc. The mounting flange 2 is wider at the M end of the straight line MN and narrower at the N end of the straight line MN.

[0063] During the manufacturing process of the fixed bracket 10 , the mounting flange 2 can be formed by bending the lower edge of the bracket body 1 , and the mounting flange 2 can also be fixedly connected to the lower edge of the bracket body 1 through a welding process.

[0064] The first straight line L1 extends toward the wider end (ie, the M end) of the mounting flange 2. In other words, the first straight line L1 extends toward the front of the bracket body 1.

[0065] In some embodiments of the present invention, reference Figure 1 As shown, the bracket body 1 can include a first part 161 and a second part 162. The first part 161 is connected to the wider end (i.e., the M end) of the mounting flange 2, and the second part 162 is connected to the narrower end (i.e., the N end) of the mounting flange 2. The first part 161 is located below the wire harness anti-cut flange 14, and the second part 162 is located below the collision flange 12, that is, the first part 161 is located at the front end of the second part 162.

[0066] The height of the first portion 161 is less than that of the second portion 162. The electrical component mounting structure further includes two second mounting bosses 112, one of which is located on the first portion 161 and the other on the second portion 162. The second mounting boss 112 on the first portion 161 is lower than the second mounting boss 112 on the second portion 162. Thus, the line L2 connecting the fixing points of the two second mounting bosses 112 extends toward the front of the bracket body 1. After the electrical component is mounted on the second mounting bosses 112, the electrical component's plug-in port 201 tilts forward and downward.

[0067] In some embodiments of the present invention, the edge of the second part 162 is provided with an auxiliary reinforcing flange 171 extending toward the second side of the bracket body 1, and a tool avoidance notch 172 is provided on the auxiliary reinforcing flange 171 located above the bracket fixing position 21. When the bracket fixing position 21 is installed, the tool avoidance notch 172 can avoid tools such as sleeves.

[0068] During the manufacturing process of the fixing bracket 10 , the auxiliary reinforcing flange 171 can be formed by bending the edge of the second portion 162 , and the auxiliary reinforcing flange 171 can also be fixedly connected to the edge of the second portion 162 through a welding process.

[0069] In some embodiments of the present invention, a portion of the stent body 1 protrudes toward the second side of the stent body 1 to form a tubular reinforcement structure 18. The tubular reinforcement structure 18 extends along the height of the stent body 1 and defines a reinforcement channel therein. The reinforcement channel extends along the height of the stent body 1. The tubular reinforcement structure 18 is located between the first portion 161 and the second portion 162. The lower end of the tubular reinforcement structure 18 extends to the mounting flange 2. The provision of the tubular reinforcement structure 18 can significantly increase the strength and rigidity of the stent body 1.

[0070] In some embodiments of the present invention, Figure 3-Figure 4 As shown, tubular reinforcement structure 18 is provided with a central lightening hole 191, which extends along the height of bracket body 1. Central lightening hole 191 reduces the weight of bracket body 1, facilitating a lightweight design for fixed bracket 10. The provision of tubular reinforcement structure 18 and central lightening hole 191 allows for optimal weight while maintaining strength.

[0071] In some embodiments of the present invention, Figure 1 、 Figure 3-Figure 4As shown, side weight-reducing holes 192 are provided on the bracket body 1 outside the tubular reinforcement structure 18, and the side weight-reducing holes 192 extend along the height direction of the bracket body 1. The side weight-reducing holes 192 can reduce the weight of the bracket body 1, which is conducive to the lightweight design of the fixed bracket 10.

[0072] exist Figure 3-Figure 4 In the specific example, a central weight-reducing hole 191 is provided on the tubular reinforcement structure 18 , and side weight-reducing holes 192 are provided on the bracket body 1 outside the tubular reinforcement structure 18 . Side weight-reducing holes 192 are provided on the front and rear sides of the central weight-reducing hole 191 .

[0073] In some embodiments of the present invention, the lower portion of the bracket body 1 is provided with a body reinforcement flange 173 extending toward the second side of the bracket body 1. The body reinforcement flange 173 is located below the collision flange 12 and the wire harness anti-cut flange 14. The installation flange 2 has an upwardly bent auxiliary flange 22. The auxiliary flange 22 at least partially overlaps with the body reinforcement flange 173, and the auxiliary flange 22 is welded and fixed to the body reinforcement flange 173. Figure 1 In the specific example, a body reinforcement flange 173 is provided below the collision flange 12 and the wire harness anti-cut flange 14. That is, the edges of the first part 161 and the second part 162 are both provided with a body reinforcement flange 173. The front and rear ends of the installation flange 2 are both provided with an upwardly bent auxiliary flange 22. The front auxiliary flange 22 is welded to the corresponding front body reinforcement flange 173, and the rear auxiliary flange 22 is welded to the corresponding rear body reinforcement flange 173. The auxiliary flange 22 and the body reinforcement flange 173 at least partially overlap, which helps to improve the connection strength between the auxiliary flange 22 and the body reinforcement flange 173.

[0074] In some embodiments of the present invention, a plurality of reinforcing ribs 3 are provided at the connection between the mounting flange 2 and the bracket body 1, thereby facilitating the improvement of the connection strength and stiffness between the mounting flange 2 and the bracket body 1, thereby facilitating the improvement of the installation strength of the fixing bracket 10 for the electrical device. Figure 1 In the specific example, there are two reinforcing ribs 3 , one of which is located at the connection between the first portion 161 and the mounting flange 2 , and the other reinforcing rib 3 is located at the connection between the second portion 162 and the mounting flange 2 .

[0075] In some embodiments, a wire harness mounting point may be provided on the fixing bracket 10 to fix the wire harness and reduce the risk of collision or cutting of the wire harness.

[0076] The following describes a fixing bracket 10 according to a specific example of the present invention.

[0077] The fixed bracket 10 includes a bracket body 1 and a mounting flange 2. The mounting flange 2 is perpendicular to the bracket body 1 and extends toward side B of the bracket body 1. Two reinforcing ribs 3 are provided at the connection between the mounting flange 2 and the bracket body 1.

[0078] According to the embodiment of the present invention, the fixed bracket 10 utilizes the collision flange 12 at the rear end of the bracket body 1, the weakening structure 13 at the lower end of the collision flange 12, and the collision blocking structure 30 positioned at the rear of the fixed bracket 10 to deform the fixed bracket 10 in the event of a collision, absorbing the energy of a vehicle collision and protecting the controller 20. The fixed bracket 10 boasts a simple and practical structure. Without sacrificing strength, it cleverly utilizes various mounting bosses, flanges, and reinforcements to reduce the number of combined mounting structures, thereby reducing weight and cost. By reducing the number of mounting points, the complexity of assembly and disassembly is reduced, improving installation and disassembly efficiency. Furthermore, the ingenious arrangement of the wire harness anti-cut flange 14 perfectly avoids any areas that could scratch or pose a risk to the wiring harness. The wire harness plug-in avoidance structure 15 reduces layout space and improves space utilization. Tool avoidance notches 172, such as crescent cuts, are added where tool clearance is required, providing ample tool space and greatly facilitating assembly and after-sales repair. The fixed bracket 10 of the present invention is well-suited for platform-based and universal application.

[0079] Combine Figure 1 、 Figure 3-Figure 5 As shown, the controller assembly 100 according to the second embodiment of the present invention may include a controller 20 and a fixing bracket 10 of the above embodiment, the controller 20 having an insertion port 201 and a first mounting hole, the insertion direction of the insertion port 201 being parallel to the first straight line L1, the number of the first mounting holes and the first mounting bosses 111 being the same, and the positions of the first mounting holes and the first mounting bosses 111 corresponding one to one, and the first mounting bosses 111 being suitable for being passed through the corresponding first mounting holes.

[0080] In some embodiments, when the fixing bracket 10 has the second mounting boss 112, the controller 20 also has a second mounting hole. For example, according to one embodiment of the present invention, when the fixing bracket 10 has the first mounting boss 111 and the second mounting boss 112, the controller 20 has the first mounting hole and the second mounting hole, the number of the first mounting holes is the same as the number of the first mounting bosses 111, and the positions of the first mounting holes and the first mounting bosses 111 correspond one-to-one, and the first mounting bosses 111 are suitable for being inserted into the corresponding first mounting holes, the number of the second mounting holes is the same as the number of the second mounting bosses 112, and the positions of the second mounting holes and the second mounting bosses 112 correspond one-to-one, and the second mounting bosses 112 are suitable for being inserted into the corresponding second mounting holes.

[0081] The mounting bosses pass through the corresponding mounting holes and then threadably engage with the nuts 40, thereby securing the controller 20 to the fixing bracket 10. To remove the controller 20 from the fixing bracket 10, first loosen and remove the nuts 40, then remove the mounting bosses from the corresponding mounting holes. The controller 20 can then be separated from the fixing bracket 10.

[0082] According to the controller assembly 100 of the embodiment of the present invention, by adopting the fixing bracket 10 of the above embodiment, the plug-in port 201 of the electrical component installed on the first mounting boss 111 can be tilted downward, thereby facilitating improvement of the waterproof performance of the electrical component plug-in port 201.

[0083] The controller assembly 100 according to a specific example of the present invention is described below.

[0084] The controller assembly 100 includes a fixing bracket 10 and a controller 20. The controller 20 has an insertion port 201, a first mounting hole and a second mounting hole. The first mounting boss 111 is inserted into the corresponding first mounting hole, and the second mounting boss 112 is inserted into the corresponding second mounting hole.

[0085] Combine Figure 1 、 Figure 3-Figure 5 As shown, a vehicle according to an embodiment of the third aspect of the present invention may include the controller assembly 100 of the above embodiment, and the controller assembly 100 is installed in the front cabin of the vehicle, with the plug port 201 facing the ground in front of the vehicle. In this way, the plug port 201 has good waterproof performance. Even if water enters the plug port 201, it will flow out of the plug port 201 due to the downward tilt of the plug port 201, thereby preventing short circuit problems caused by water accumulation at the plug port 201.

[0086] The vehicle according to the embodiment of the present invention, by adopting the controller assembly 100 of the above embodiment, is conducive to improving the waterproof performance of the vehicle.

[0087] In some embodiments of the present invention, projection nuts are provided on the vehicle frame within the front engine compartment. Bracket fixing positions 21 are bracket fixing holes. The number of projection nuts is the same as the number of bracket fixing holes, and the positions of the projection nuts and bracket fixing holes correspond one-to-one. Bolts 50 pass through the corresponding bracket fixing holes and are fastened to the corresponding projection nuts. This allows the mounting and securing of the fixed bracket 10 on the vehicle frame, thereby also securing the controller assembly 100 on the vehicle frame. When the controller assembly 100 needs to be removed from the vehicle frame, the bolts 50 are loosened to withdraw from the corresponding projection nuts, allowing the entire controller assembly 100 to be removed.

[0088] Optionally, the vehicle frame may be a crossbeam or a longitudinal beam.

[0089] In some embodiments of the present invention, a collision blocking structure 30 is provided in the front cabin, and the fixed bracket 10 is located in front of the collision blocking structure 30. In other words, the controller assembly 100 is located in front of the collision blocking structure 30 as a whole. When the vehicle collides, the collision flange 12 of the fixed bracket 10 invades the cab and is blocked by the collision blocking structure 30 in the front cabin. The weakening structure 13 at the end of the collision flange 12 collapses and deforms, causing the bracket body 1 to deform. The electrical components rotate with the bracket body 1, and the deformation of the bracket body 1 absorbs the destructive energy of the collision, preventing the electrical components from being directly damaged by external forces, thereby protecting the electrical components from failure. After the bracket body 1 deforms and rotates, the collision flange 12 moves upward. The collision flange 12 has a certain load-bearing function and can support pedestrians. At the same time, it can also prevent the original sharp edge structure above the fixed bracket 10 from scratching pedestrians.

[0090] Optionally, the collision blocking structure 30 may be a water guide groove.
