Description

Technical Field

[0001] This utility model relates to the field of vehicle body technology, and in particular to a dashboard reinforcement beam. This utility model also relates to vehicles using this dashboard reinforcement beam. Background Technology

[0002] In automotive design, dashboard reinforcement beams play a crucial role, supporting the instrument panel and various devices while effectively absorbing and dispersing impact forces during a collision to protect the safety of vehicle occupants.

[0003] The dashboard reinforcement beam assembly requires the installation of components such as the dashboard, air conditioning, steering column, wiring harness, and fragrance system to form the dashboard assembly. During the assembly process of the dashboard assembly, also known as the sub-assembly process, a tooling bracket, specifically the reinforcement beam sub-assembly bracket, is needed. After the dashboard assembly has completed the assembly of all its components, it needs to be installed onto the reinforcement beam final assembly bracket. This process is the final assembly process, which also requires a tooling bracket, specifically the reinforcement beam final assembly bracket.

[0004] The existing dashboard reinforcement beam has sub-assembly mounting brackets and final assembly mounting brackets on both the front and rear sides at its length, for sub-assembly and final assembly respectively. However, this structure has problems. Due to the large number of mounting brackets, the structure is complex, leading to increased vehicle management and production costs. Furthermore, each mounting bracket requires a separate mold, increasing development costs. Additionally, each mounting bracket needs to be bolted to the dashboard reinforcement beam body, a process that requires manual assembly, consuming time, and is prone to assembly problems due to tolerances during vehicle installation. Utility Model Content

[0005] In view of this, the present invention aims to provide an instrument panel reinforcing beam that is convenient to process and easy to assemble and reassemble.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] An instrument panel reinforcing beam includes an instrument panel reinforcing beam body and mounting brackets arranged at both ends of the reinforcing beam body along its length.

[0008] The mounting brackets at both ends are located on the same side of the reinforcing beam body. Each mounting bracket is provided with a first mounting part and a second mounting part. The first mounting part is used to install the instrument panel reinforcing beam body onto the reinforcing beam sub-assembly bracket, and the second mounting part is used to install the instrument panel reinforcing beam body onto the reinforcing beam sub-assembly bracket / reinforcing beam sub-assembly bracket.

[0009] Furthermore, the instrument panel reinforcing beam has a cavity, which is open on the side facing the front of the vehicle. Each mounting bracket is located on the side of the instrument panel reinforcing beam facing the rear of the vehicle, and each mounting bracket has a cavity communicating with the cavity.

[0010] Furthermore, each of the mounting brackets includes two mounting plates arranged at a distance, and a connecting plate connecting the two mounting plates, with the cavity formed between the two mounting plates and the connecting plate.

[0011] Furthermore, the cavity is provided with reinforcing ribs, and the reinforcing ribs are connected between the two mounting plates.

[0012] Furthermore, the mounting bracket has an arc-shaped notch on the side away from the main body of the instrument panel reinforcing beam.

[0013] Furthermore, the first mounting portion includes a first through hole that extends through both mounting plates, and the axis of the first through hole is arranged along the left-right direction of the vehicle.

[0014] Furthermore, the second mounting part is located below the first mounting part and includes a second through hole that passes through both mounting plates, and the axis of the second through hole is arranged along the left-right direction of the vehicle.

[0015] Furthermore, the mounting bracket is provided with an anti-rotation part, which is used to prevent the dashboard reinforcing beam body from rotating relative to at least one of the reinforcing beam sub-mount bracket and the reinforcing beam sub-mount bracket.

[0016] Furthermore, the instrument panel reinforcing beam is made of magnesium alloy; and / or, the instrument panel reinforcing beam is integrally formed using a die-casting process.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] (1) The instrument panel reinforcing beam described in this utility model has an installation bracket set on only one side of the instrument panel reinforcing beam body, and a first installation part and a second installation part are set on each installation bracket. Without affecting the sub-assembly and final assembly, the instrument panel reinforcing beam can be integrally formed by die casting process, requiring only one mold. This not only improves production efficiency, but also greatly simplifies the processing and manufacturing process. At the same time, the number of parts is small, which can reduce the number of parts required in the traditional assembly method, such as bolts and connection processes, thereby reducing management and production costs. It can also reduce tolerances in the assembly process and prevent problems of difficult assembly when loading the vehicle.

[0019] (2) The instrument panel reinforcement beam has a cavity and is open on the side facing the front of the vehicle, which can effectively reduce the weight of the instrument panel reinforcement beam. Each mounting bracket is placed on the side of the instrument panel reinforcement beam facing the rear of the vehicle, so that the cavity in the mounting bracket is connected to the cavity, which is convenient for integral molding by die casting process.

[0020] (3) The mounting bracket includes two mounting plates spaced apart and a connecting plate between the two mounting plates. The instrument panel reinforcing beam is more convenient to process using die casting. At the same time, it can better ensure the structural strength of the mounting bracket, thereby preventing the instrument panel reinforcing beam from shaking during sub-assembly and final assembly, and improving the structural stability of the instrument panel reinforcing beam during sub-assembly and final assembly.

[0021] (4) Reinforcing ribs are set in the cavity. The reinforcing ribs can act as a skeleton and further improve the structural strength and rigidity of the mounting bracket. This ensures the stability of the instrument panel reinforcing beam body during the sub-assembly and final assembly of the mounting bracket. Connecting the reinforcing ribs between the two mounting plates has a good effect on improving the structural strength and rigidity of the mounting bracket.

[0022] (5) Setting an arc-shaped notch on the mounting bracket can effectively reduce the weight of the mounting bracket, thus meeting the requirements for vehicle lightweighting. At the same time, setting the notch to an arc shape can effectively prevent stress concentration.

[0023] (6) The first mounting part includes a first through hole that runs through both mounting plates, and the axis of the first through hole is arranged along the left and right direction of the whole vehicle, which facilitates the cooperation with the existing reinforcing beam sub-mount bracket, thereby reducing processing costs. This structure is also conducive to the use of die casting process to form the instrument panel reinforcing beam.

[0024] (7) The second mounting section includes a second through hole that runs through both mounting plates. The axis of the second through hole is arranged along the left and right direction of the vehicle. This structure is conducive to the use of die casting process for the instrument panel reinforcing beam and is convenient to cooperate with the existing reinforcing beam assembly bracket, which helps to reduce processing costs.

[0025] (8) An anti-rotation part is provided on the mounting bracket. The anti-rotation part prevents the main body of the instrument panel reinforcing beam from flipping relative to the reinforcing beam sub-assembly bracket. This prevents the main body of the instrument panel reinforcing beam from flipping during the sub-assembly process, which is conducive to the smooth progress of the sub-assembly process. The anti-rotation part prevents the main body of the instrument panel reinforcing beam from flipping relative to the reinforcing beam final assembly bracket. This prevents the main body of the instrument panel reinforcing beam from flipping during the final assembly process, which is conducive to the smooth progress of the final assembly process.

[0026] (9) The instrument panel reinforcement beam is made of magnesium alloy, which has a significant weight reduction effect, helps to reduce the overall weight of the vehicle, improve fuel economy and performance, and has good mechanical properties, heat dissipation performance and electromagnetic shielding performance. The instrument panel reinforcement beam is integrally formed by die casting, which can reduce the structural weak points that may be caused by the connection of parts, and enhance the overall strength and reliability of the reinforcement beam.

[0027] Another objective of this invention is to provide a vehicle equipped with a dashboard reinforcement beam as described above.

[0028] Compared with the prior art, this utility model has the following advantages:

[0029] The vehicle described in this utility model, by adopting the above-mentioned dashboard reinforcement beam, can reduce the number of parts, simplify the vehicle production process, and improve the vehicle production efficiency. It can also reduce the number of molds to be developed, thereby reducing the vehicle production cost. Furthermore, the high overall strength and reliability of the dashboard reinforcement beam can be utilized to improve the front impact resistance of the vehicle. Attached Figure Description

[0050] In automotive design, dashboard reinforcement beams play a crucial role, supporting the instrument panel and various devices while effectively absorbing and dispersing impact forces during a collision to protect the safety of vehicle occupants.

[0051] The dashboard reinforcement beam assembly requires the installation of components such as the dashboard, air conditioning, steering column, wiring harness, and fragrance system to form the dashboard assembly. During the assembly process of the dashboard assembly, i.e., the sub-assembly process, a reinforcement beam sub-assembly bracket is needed. After the dashboard assembly has completed the assembly of all its components, it needs to be installed onto the reinforcement beam final assembly bracket; this process is the final assembly process, which also requires the reinforcement beam final assembly bracket.

[0052] The existing dashboard reinforcement beam has sub-assembly mounting brackets and final assembly mounting brackets on both the front and rear sides at its length, for sub-assembly and final assembly respectively. However, this structure has problems: the large number of mounting brackets leads to structural complexity, increasing vehicle management and production costs. Furthermore, each mounting bracket requires a separate mold, increasing development costs. Additionally, the four mounting brackets require six bolts to be installed onto the dashboard reinforcement beam body; this process requires manual assembly, consuming time, and assembly tolerances can lead to assembly difficulties during vehicle installation.

[0053] In view of this, to overcome the shortcomings of the prior art, an embodiment of the first aspect of this utility model provides a dashboard reinforcing beam. Combined with... Figure 1 and Figure 3 As shown, in the dashboard reinforcement beam of this embodiment, the dashboard reinforcement beam is designed to include a dashboard reinforcement beam body 1 and mounting brackets 2 arranged at both ends of the reinforcement beam body along its length.

[0054] The mounting brackets 2 at both ends are located on the same side of the main body of the reinforcing beam. Each mounting bracket 2 is provided with a first mounting part 20a and a second mounting part 20b. The first mounting part 20a is used to install the main body of the instrument panel reinforcing beam 1 on the reinforcing beam sub-assembly bracket, and the second mounting part 20b is used to install the main body of the instrument panel reinforcing beam 1 on the reinforcing beam final assembly bracket.

[0055] For ease of understanding, it should be noted that the so-called reinforcing beam sub-assembly bracket is used to fix the instrument panel reinforcing beam body 1. When the instrument panel reinforcing beam body 1 is fixed to the reinforcing beam sub-assembly bracket by the first mounting part 20a, the instrument panel, air conditioner, steering column, wiring harness, fragrance and other components can be installed on the instrument panel reinforcing beam body 1 to form the instrument panel assembly.

[0056] The so-called reinforcing beam assembly bracket is used to fix the instrument panel assembly. When the instrument panel assembly is fixed to the reinforcing beam assembly bracket by the second mounting part 20b, the instrument panel assembly can be lifted by the reinforcing beam assembly bracket and then installed on the vehicle body.

[0057] In this embodiment, the instrument panel reinforcing beam has a mounting bracket 2 on only one side of the main body 1. A first mounting part 20a and a second mounting part 20b are simultaneously provided on each mounting bracket 2. This allows the instrument panel reinforcing beam to be integrally formed using die casting without affecting the individual assembly and final assembly, requiring only one mold. This not only improves production efficiency but also greatly simplifies the manufacturing process. Furthermore, the fewer parts required in traditional assembly methods reduce the need for multiple components such as bolts and connection processes, thereby reducing management and production costs. It also reduces tolerances during assembly, preventing assembly difficulties during vehicle loading. For a better understanding of the instrument panel reinforcing beam in this embodiment, please refer to [reference needed]. Figure 1 The structure of the instrument panel reinforcing beam body 1 is briefly described. It mainly includes the instrument panel reinforcing beam body 101, as well as the central channel bracket 102, end mounting bracket 103 and instrument panel mounting bracket 104 integrally formed on the instrument panel reinforcing beam body 101.

[0058] The instrument panel reinforcing beam body 101 extends along the left and right direction of the vehicle, and the lower middle part of the instrument panel reinforcing beam body 101 is connected to the upper part of the central channel bracket 102. The lower part of the central channel bracket is connected to the central channel of the floor (not shown in the figure), which facilitates the fixing of the instrument panel reinforcing beam.

[0059] It should be noted that, in order to improve the support strength of the center channel bracket 102, in one exemplary embodiment, the center channel bracket 102 includes support beams located on both sides and a connecting beam connecting the support beams on both sides. The center channel bracket 102 supports the instrument panel reinforcing beam body 101 above the floor through the support beams on both sides, and the connecting beam connects the support beams on both sides, which can effectively improve the structural strength of the center channel bracket 102 itself, thereby improving the support strength of the instrument panel reinforcing beam body 101. For example, in this embodiment, the connecting beam extends along the left and right direction of the whole vehicle, so that it can form a ring with the support beams at both ends and the instrument panel reinforcing beam body 101, which can effectively improve the overall structural strength and stiffness of the instrument panel reinforcing beam.

[0060] Furthermore, end mounting brackets 103 are provided at both ends of the instrument panel reinforcing beam body 101. The end mounting brackets 2 extend along the vertical direction of the vehicle, and in specific implementations, each end mounting bracket 2 has an extension section. The extension sections on each end mounting bracket 2 extend towards the interior side along the horizontal direction of the vehicle, making the shape of both end mounting brackets 2 "L". In practical applications, each end mounting bracket 2 is provided with mounting holes, which facilitates fixing the instrument panel (not shown in the figure) to the end mounting bracket 2.

[0061] To better secure the instrument panel, multiple instrument panel mounting brackets 104 are provided on the upper side of the instrument panel reinforcing beam body 101, for example... Figure 1 and Figure 4 The diagram shows four instrument panel mounting brackets 104. Multiple instrument panel mounting brackets 104 are arranged at intervals along the left-right direction of the vehicle, and each instrument panel mounting bracket 104 is elongated and extends in a direction orthogonal to the left-right direction of the vehicle. It should be understood that the number of instrument panel mounting brackets 104 can be four, or other numbers.

[0062] Each instrument panel mounting bracket 104 is used to mount the instrument panel. It should be noted that, for ease of overall arrangement, some of the multiple instrument panel mounting brackets 104 can also be used to mount a display screen (not shown in the figure), thus allowing this portion of the instrument panel mounting brackets 104 to simultaneously fix both the instrument panel and the display screen, reducing the number of mounting brackets 2 and meeting the vehicle's lightweight requirements. The specific instrument panel mounting brackets 104 used can be arranged according to actual needs.

[0063] Based on the above general overview, in some exemplary implementations, such as Figure 4 and Figure 5 As shown, the instrument panel reinforcing beam has a cavity 10a, which is open on the side facing the front of the vehicle. Each mounting bracket 2 is located on the side of the instrument panel reinforcing beam body 1 facing the rear of the vehicle, and each mounting bracket 2 has a cavity 20c that communicates with the cavity 10a.

[0064] In the above structure, a cavity 10a is provided in the instrument panel reinforcing beam, and the cavity 10a is opened on the side facing the front of the vehicle, which can effectively reduce the weight of the instrument panel reinforcing beam. Each mounting bracket 2 is located on the side of the instrument panel reinforcing beam body 1 facing the rear of the vehicle, so that the cavity 20c in the mounting bracket 2 is connected to the cavity 10a, which facilitates the integral molding by die casting process.

[0065] It should be noted that the instrument panel reinforcing beam body 101, the central channel bracket 102, the end mounting bracket 103, and the instrument panel mounting bracket 104 are all provided with sub-cavities. The sub-cavities in these components are interconnected, thereby forming the aforementioned cavity 10a. This facilitates the integral molding of the instrument panel reinforcing beam using a die-casting process, and the instrument panel reinforcing beam can achieve a good weight reduction effect while ensuring structural strength.

[0066] To enhance the main body 1 of the instrument panel reinforcing beam, multiple reinforcing plates can be arranged in each of the aforementioned sub-cavities as needed. For example, multiple reinforcing plates in the main body 101 of the instrument panel reinforcing beam are arranged at intervals along the left-right direction of the vehicle, multiple reinforcing plates in the end mounting bracket 103 are arranged at intervals along the up-down direction of the vehicle, multiple reinforcing plates in the two support beams of the center channel bracket 102 are arranged at intervals along the up-down direction of the vehicle, and multiple reinforcing plates in the connecting beam of the center channel bracket 102 are arranged at intervals along the left-right direction of the vehicle. In order to improve the reinforcing effect, the arrangement angles of any two adjacent reinforcing plates are different, which is beneficial to improving the overall structural strength and rigidity of the instrument panel reinforcing beam.

[0067] Still refer to Figures 1 to 3 As shown, in some exemplary embodiments, each mounting bracket 2 includes two mounting plates 201 arranged at a distance, and a connecting plate 202 connecting the two mounting plates 201, with a cavity 20c formed between the two mounting plates 201 and the connecting plate 202.

[0068] The mounting bracket 2 includes two mounting plates 201 spaced apart, and a connecting plate 202 connecting the two mounting plates 201. The instrument panel reinforcing beam is more convenient to process using die casting, and at the same time, it can better ensure the structural strength of the mounting bracket 2, thereby preventing the instrument panel reinforcing beam from shaking during sub-assembly and final assembly, and improving the structural stability of the instrument panel reinforcing beam during sub-assembly and final assembly.

[0069] The cavity 20c formed between the two mounting plates 201 and the connecting plate 202 not only has a good weight reduction effect, meeting the vehicle's lightweight requirements, but also better ensures the structural strength of each mounting bracket 2, thereby improving the reliability of fixing the instrument panel reinforcement beam during the sub-assembly and final assembly processes.

[0070] In some of the exemplary implementations, such as Figure 4 and Figure 5 As shown, the cavity 20c of the mounting bracket 2 is provided with a reinforcing rib 203, and the reinforcing rib 203 is connected between the two mounting plates 201. The reinforcing rib 203 in the cavity 20c acts as a skeleton, further improving the structural strength and rigidity of the mounting bracket 2. This ensures better stability of the instrument panel reinforcing beam body 1 during disassembly and final assembly. Connecting the reinforcing rib 203 between the two mounting plates 201 effectively improves the structural strength and rigidity of the mounting bracket 2.

[0071] Reference Figure 2 and Figure 3 As shown, in some exemplary embodiments, the mounting bracket 2 has an arc-shaped notch 20d on the side away from the instrument panel reinforcing beam body 1, which can better reduce the weight of the mounting bracket 2 and meet the vehicle lightweighting requirements.

[0072] It should be noted that, in the preferred embodiment, the first mounting portion 20a and the second mounting portion 20b are arranged with a vertical spacing, facilitating the application of the instrument panel reinforcing beam in the sub-assembly and final assembly processes, respectively. In some examples, the notch 20d is positioned between the first mounting plate 201 and the second mounting plate 201, which can better utilize the arrangement space on the mounting bracket 2, without affecting the reliability of the instrument panel reinforcing beam during sub-assembly and final assembly, while also achieving a good weight reduction effect. Furthermore, the notch 20d is arc-shaped, which can also effectively prevent stress concentration.

[0073] Still refer to Figure 2 and Figure 3 As shown, in some exemplary embodiments, the first mounting portion 20a includes a first through hole that extends through both mounting plates 201, with the axis of the first through hole arranged along the left-right direction of the vehicle. The inclusion of a first through hole extending through both mounting plates 201, with the axis of the first through hole arranged along the left-right direction of the vehicle, facilitates compatibility with existing reinforcing beam mounting brackets, thereby reducing processing costs. Furthermore, this structure allows for the use of die-casting to form the instrument panel reinforcing beam.

[0074] Continue to refer to Figure 2 and Figure 3 As shown, the first through hole is preferably a circular hole, so that it can be used with the existing reinforcing beam sub-assembly bracket. Specifically, the two circular locating pins on the reinforcing beam sub-assembly bracket can be inserted into the first through hole at the corresponding position, which facilitates the installation of wiring harnesses, instrument panels, air conditioners, pipe columns and other components, thereby assembling the instrument panel assembly.

[0075] It should be understood that, in addition to a circular hole, the first through hole can also be other shapes, such as square or triangular. However, this would require adjusting the corresponding fitting structure on the existing reinforcing beam assembly bracket.

[0076] In some of these exemplary implementations, reference is still made to... Figure 2 and Figure 3 As shown, the second mounting portion 20b is located below the first mounting portion 20a and includes a second through hole that extends through both mounting plates 201, with the axis of the second through hole arranged along the left-right direction of the vehicle. This structure facilitates the use of die-casting for the instrument panel reinforcing beam and allows for easy integration with existing reinforcing beam assembly brackets, thereby reducing processing costs.

[0077] In some preferred examples, the second through hole is an irregularly shaped hole. For example, in this embodiment, part of the second through hole is square and the other part is semi-circular. The reinforcing beam assembly bracket is provided with an irregularly shaped guide pin. The irregularly shaped guide pin is inserted into the second through hole to facilitate the hoisting of the instrument panel assembly and then its installation on the vehicle body.

[0078] This allows the second through hole to not only serve as a mounting hole for installing the instrument panel reinforcing beam body 1 onto the reinforcing beam assembly bracket, but also to effectively prevent the instrument panel reinforcing beam from flipping over during the assembly process.

[0079] like Figure 3 As shown, in some of the exemplary embodiments, the mounting bracket 2 is provided with an anti-rotation part 20e, which is used to prevent the dashboard reinforcing beam body 1 from rotating relative to at least one of the reinforcing beam sub-mount bracket and the reinforcing beam sub-mount bracket.

[0080] An anti-rotation part 20e is provided on the mounting bracket 2. The anti-rotation part 20e prevents the instrument panel reinforcing beam body 1 from flipping relative to the reinforcing beam sub-assembly bracket, which can prevent the instrument panel reinforcing beam body 1 from flipping during the sub-assembly process and facilitate the smooth progress of the sub-assembly process. The anti-rotation part 20e also prevents the instrument panel reinforcing beam body 1 from flipping relative to the reinforcing beam final assembly bracket, which can prevent the instrument panel reinforcing beam body 1 from flipping during the final assembly process and facilitate the smooth progress of the final assembly process.

[0081] For example, in the aforementioned example, the second through hole constitutes an anti-rotation part 20e, which can be used to better prevent the dashboard reinforcing beam from tipping over during final assembly. Furthermore, to better prevent the dashboard reinforcing beam from tipping over during sub-assembly, Figure 3 The anti-rotation part 20e shown in the figure preferably adopts a through hole provided on the mounting bracket 2, which cooperates with the aforementioned first through hole to prevent the instrument panel reinforcement beam from flipping during the assembly process.

[0082] In some exemplary embodiments, the dashboard reinforcement beam is made of magnesium alloy, such as the existing AM60B. It should be noted that in this embodiment, the dashboard reinforcement beam is made of magnesium alloy, which has a significant weight-loss effect, helping to reduce the overall vehicle weight, improve fuel economy and performance, while also possessing good mechanical properties, heat dissipation performance, and electromagnetic shielding performance. It should be understood that, in addition to magnesium alloy, other materials such as steel and aluminum alloy can also be used for the dashboard reinforcement beam.

[0083] In a preferred embodiment, the instrument panel reinforcing beam is integrally formed using a die-casting process, which reduces potential structural weaknesses caused by component connections and enhances the overall strength and reliability of the reinforcing beam.

[0084] Finally, it should be noted that the magnesium alloy used in the instrument panel reinforcement beam of this embodiment has a density of 1780 kg / m³. 3 The total weight is 5.019 kg, compared to the traditional steel mounting bracket with a density of 7850 kg / m³. 3 The instrument panel reinforcement beam has a good weight reduction effect.

[0085] The existing instrument panel reinforcement beam with four separate mounting brackets 2 weighs 5.255 kg. The original mounting bracket 2 weighs 0.455 kg and costs 8 yuan. After integration, the mounting bracket 2 weighs 0.219 kg and costs 4 yuan, thus reducing the weight by 0.236 kg, approximately 52%, and the cost by 4 yuan, approximately 50%. In addition, it saves the cost of four sets of individual molds, reduces the overall weight of the instrument panel reinforcement beam assembly by 4.5%, and reduces the total cost by 1%.

[0086] It is worth noting that, regarding the dashboard reinforcement beam in this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still made of... Figures 1 to 5 As shown in the image.

[0087] The instrument panel reinforcing beam is integrally formed by die casting and includes an instrument panel reinforcing beam body 1 and mounting brackets 2 arranged at both ends along the length of the reinforcing beam body. The mounting brackets 2 at both ends are located on the same side of the reinforcing beam body. Each mounting bracket 2 is provided with a first through hole and a second through hole. The first through hole is used to install the instrument panel reinforcing beam body 1 on the reinforcing beam sub-assembly bracket, and the second through hole is used to install the instrument panel reinforcing beam body 1 on the reinforcing beam final assembly bracket.

[0088] The instrument panel reinforcing beam has a cavity 10a, which is open on the side facing the front of the vehicle. Each mounting bracket 2 is located on the side of the instrument panel reinforcing beam body 1 facing the rear of the vehicle, and each mounting bracket 2 has a cavity 20c communicating with the cavity 10a. Each mounting bracket 2 includes two mounting plates 201 arranged at intervals, and a connecting plate 202 connecting the two mounting plates 201. The cavity 20c is formed between the two mounting plates 201 and the connecting plate 202.

[0089] The cavity 20c is equipped with a reinforcing rib 203, which connects the two mounting plates 201. The first and second through holes are arranged vertically at a distance, and the mounting bracket 2 is provided with a weight-reducing groove located between the first and second through holes. The axes of the first and second through holes are both arranged along the left-right direction of the vehicle.
