Description

Technical Field

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

[0002] The dashboard reinforcement beam assembly is a crucial component of a car, supporting the instrument panel and various devices while effectively absorbing and dispersing impact forces during a collision to protect the safety of occupants. Components such as the dashboard, air conditioning, steering column, wiring harness, and air purifier all need to be installed on the dashboard reinforcement beam assembly to form it; this installation process is the sub-assembly process of the dashboard reinforcement beam. Then, the dashboard reinforcement beam assembly is installed onto the vehicle body; this process is the final assembly process of the dashboard reinforcement beam.

[0003] Existing instrument panel reinforcement beams typically have two types of mounting brackets, one for the initial assembly and the other for the final assembly. These brackets only function during the assembly of the instrument panel reinforcement beam assembly and the overall vehicle assembly. Once the instrument panel reinforcement beam assembly is complete and installed on the vehicle body, the brackets cease to provide support or installation, but remain on the vehicle. This increases the overall weight and cost of the vehicle, and negatively impacts handling and fuel economy. Utility Model Content

[0004] In view of this, this application aims to propose a dashboard reinforcement beam assembly to meet the requirements of vehicle lightweighting.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0007] Along the left-right direction of the vehicle, the instrument panel reinforcing beam body is provided with the first mounting bracket and the second mounting bracket near both ends, and the first mounting bracket and the second mounting bracket at each end are respectively placed on the front and rear sides of the instrument panel reinforcing beam body. The first mounting bracket is used to install the instrument panel reinforcing beam body on the reinforcing beam sub-assembly fixture, and the second mounting bracket is used to install the instrument panel reinforcing beam body on the reinforcing beam final assembly fixture.

[0015] Furthermore, the second longitudinal plate is provided with a second anti-rotation part, which is connected to the second anti-rotation mating part on the reinforcing beam assembly fixture, thereby preventing the instrument panel reinforcing beam body from rotating relative to the reinforcing beam assembly fixture.

[0016] Compared with related technologies, this application has the following advantages:

[0017] (1) The instrument panel reinforcement beam assembly described in this application has a first mounting bracket and a second mounting bracket provided on the front and rear sides of the instrument panel reinforcement beam body. During the sub-assembly and final assembly of the instrument panel reinforcement beam, it is convenient to cooperate with the existing reinforcement beam sub-assembly and final assembly tooling. The first mounting bracket and the second mounting bracket can be detachably installed on the instrument panel reinforcement beam body. When the instrument panel reinforcement beam assembly is installed on the vehicle body, the cost and total weight of the vehicle can be reduced by removing the first mounting bracket and the second mounting bracket. This not only meets the vehicle's lightweight requirements, but also helps to improve the vehicle's handling and fuel economy.

[0018] (2) Each first mounting bracket includes intersecting first horizontal plates and first vertical plates, which increases the rigidity of the first mounting bracket. This intersecting arrangement structure has stronger resistance to deformation and can effectively disperse and bear forces from different directions, thereby improving the overall structural stability of the first mounting bracket. The first horizontal plate is detachably connected to the instrument panel reinforcing beam body through the first fastener, making the installation and disassembly of the first mounting bracket more convenient and faster. A first connecting part is provided on the first vertical plate to facilitate the improvement of the reliability and stability of the connection between the first mounting bracket and the reinforcing beam assembly fixture.

[0019] (3) The first connecting part includes a first through hole on the first longitudinal plate, which facilitates connection with the reinforcing beam assembly fixture and helps to ensure installation efficiency. The axial direction of the first through hole is arranged along the left and right direction of the whole vehicle, which facilitates connection with the existing reinforcing beam assembly fixture. A first flange is provided in the circumference of the first through hole, which helps to improve the structural strength of the edge of the first through hole, thereby improving the reliability of the application of the first mounting bracket.

[0020] (4) A second flange is provided on the edge of at least one of the first horizontal plate and the first vertical plate, which is beneficial to improving the structural strength and rigidity of the second mounting bracket. A weight-reducing hole is provided on at least one of the first vertical plates, which is beneficial to reduce the total weight of the first mounting bracket and reduce the amount of material used, thus saving costs. A third flange is provided on the edge of the weight-reducing hole, which can better improve the structural strength of the edge of the weight-reducing hole, and further improve the reliability of the application of the first mounting bracket.

[0021] (5) The first anti-rotation part provided on the first longitudinal plate is used to prevent the instrument panel reinforcing beam body from flipping relative to the reinforcing beam sub-assembly fixture, so as to facilitate the assembly of each component onto the instrument panel reinforcing beam body, ensure the smooth progress of the sub-assembly process, and improve assembly efficiency and assembly quality.

[0022] (6) Each second mounting bracket includes intersecting second horizontal and second vertical plates, which increases the rigidity of the second mounting bracket. This intersecting arrangement provides stronger resistance to deformation and effectively disperses and bears forces from different directions, thereby improving the overall structural stability of the second mounting bracket. The second horizontal plate is detachably connected to the instrument panel reinforcing beam body via a second fastener, making the installation and disassembly of the second mounting bracket more convenient and faster. A second connecting part is provided on the second vertical plate to improve the reliability and stability of the connection between the second mounting bracket and the reinforcing beam assembly tooling.

[0023] (7) The second connecting part includes a second through hole, which facilitates connection with the reinforcing beam assembly tooling and helps ensure installation efficiency. The axial direction of the second through hole is arranged along the left and right direction of the whole vehicle, which facilitates connection with the existing reinforcing beam assembly tooling. A fourth flange is provided in the circumference of the second through hole, which helps to improve the structural strength of the edge of the second through hole, thereby improving the reliability of the application of the second mounting bracket.

[0024] (8) A fifth flange is provided at the edge of at least one of the second horizontal plate and the second vertical plate, which is beneficial to improve the structural strength and rigidity of the second mounting bracket.

[0025] (9) The second anti-rotation part provided on the second longitudinal plate is used to prevent the instrument panel reinforcing beam body from flipping relative to the reinforcing beam assembly tooling, so as to facilitate the installation of the instrument panel reinforcing beam body with multiple components onto the vehicle body, which can ensure the smooth progress of the final assembly process and improve assembly efficiency and assembly quality.

[0026] Another object of this application is to provide a vehicle having an instrument panel reinforcement beam assembly as described above.

[0027] The vehicle described in this application can reduce its weight by applying the aforementioned dashboard reinforcement beam assembly, which helps to reduce fuel consumption and improve vehicle handling. In addition, since the disassembled first and second mounting brackets can be used for the sub-assembly and final assembly processes of other vehicles, and the first and second mounting brackets do not need to be retained on the final vehicle, the cost of the vehicle is reduced.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0048] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

In the drawings, the left arrow points to the left side of the vehicle, and the right arrow points to the right side. The terms "inner" and "outer" are relative. "Inner" refers to the interior space of the vehicle, while "outer" refers to the exterior of the vehicle, i.e., the area away from the interior space.

[0053] An embodiment of the first aspect of this application provides an instrument panel reinforcement beam assembly that does not affect the sub-assembly and final assembly process of the instrument panel reinforcement beam, and helps to reduce the total weight and cost of the vehicle, thus having good practicality.

[0054] The dashboard reinforcement beam plays a crucial role in the vehicle's structure, supporting the instrument panel and various devices while effectively absorbing and dispersing impact forces during a collision to protect the safety of occupants. Components such as the dashboard, air conditioning, steering column, wiring harness, and air purifier are all mounted on the dashboard reinforcement beam, forming the dashboard reinforcement beam assembly. The assembly of the dashboard reinforcement beam assembly requires sub-assembly fixtures, and the final assembly of the dashboard reinforcement beam assembly requires final assembly fixtures.

[0055] Traditional dashboard reinforcement beams are equipped with two types of mounting brackets, one for each of the sub-assembly and final assembly processes. These brackets are typically fixed to the vehicle body structure during the design phase. While this fixed design provides stability and strength during installation, once the dashboard reinforcement beam assembly is complete, the mounting brackets lose their functional value. Instead, they increase the vehicle's weight and cost, and negatively impact handling and fuel economy. Furthermore, fixed mounting brackets cause inconvenience during subsequent maintenance and upgrades, limiting the flexibility of modular vehicle design.

[0056] In view of this, in order to overcome the shortcomings of the related technology, the dashboard reinforcement beam assembly of this embodiment combines... Figure 1 and Figure 2 As shown, the overall design includes a dashboard reinforcing beam body 1, and a first mounting bracket 2 and a second mounting bracket 3 that are detachably connected to the dashboard reinforcing beam body 1.

[0057] Along the left-right direction of the whole vehicle, the instrument panel reinforcing beam body 1 is provided with a first mounting bracket 2 and a second mounting bracket 3 near both ends. The first mounting bracket 2 and the second mounting bracket 3 at each end are respectively placed on the front and rear sides of the instrument panel reinforcing beam body 1. The first mounting bracket 2 is used to install the instrument panel reinforcing beam body 1 on the reinforcing beam sub-assembly fixture, and the second mounting bracket 3 is used to install the instrument panel reinforcing beam body 1 on the reinforcing beam final assembly fixture.

[0058] The instrument panel reinforcement beam assembly of this application includes first mounting brackets 2 and second mounting brackets 3 on both the front and rear sides of the instrument panel reinforcement beam body 1. This facilitates compatibility with existing reinforcement beam assembly and final assembly fixtures during the sub-assembly and final assembly processes of the instrument panel reinforcement beam body 1. Both the first mounting brackets 2 and second mounting brackets 3 are detachably mounted on the instrument panel reinforcement beam body 1. When the instrument panel reinforcement beam assembly is installed on the vehicle body, the cost and overall weight of the vehicle can be reduced by removing the first mounting brackets 2 and second mounting brackets 3. This not only meets the requirements for vehicle lightweighting but also improves vehicle handling and fuel economy, and reduces carbon emissions, aligning with the trend of environmental protection and emission reduction.

[0059] For ease of understanding, it should be noted that the so-called reinforcing beam sub-assembly fixture is used to fix the instrument panel reinforcing beam body 1. When the instrument panel reinforcing beam body 1 is fixed on the reinforcing beam sub-assembly fixture, 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 reinforcing beam assembly. This installation process is the sub-assembly process of the instrument panel reinforcing beam body 1.

[0060] The so-called reinforcing beam assembly fixture is used to fix the instrument panel reinforcing beam assembly. When the instrument panel reinforcing beam assembly is fixed on the reinforcing beam assembly fixture, the instrument panel reinforcing beam assembly can be lifted up with the help of the reinforcing beam assembly fixture and then installed on the vehicle body. This installation process is the final assembly process of the instrument panel reinforcing beam body 1.

[0061] In some examples, the aforementioned instrument panel reinforcing beam body 1 is integrally formed using a die-casting process, which can reduce structural weak points that may arise from the connection of parts and enhance the overall strength and reliability of the instrument panel reinforcing beam body 1.

[0062] To better understand the instrument panel reinforcement beam assembly of this embodiment, please refer to the following: Figure 1 and Figure 2 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.

[0063] In one example, the dashboard reinforcing beam body 101, the center channel bracket 102, the end mounting bracket 103, and the dashboard mounting bracket 104 are all provided with cavities 10a, and the cavities 10a are open on the side facing the front of the vehicle. Each cavity 10a is provided with multiple reinforcing ribs, and the cavities 10a are interconnected to facilitate integral molding by die casting. Preferably, the dashboard reinforcing beam body 101 is made of magnesium alloy.

[0064] The instrument panel reinforcing beam body 101 extends along the left and right direction of the vehicle. In the left and right direction of the vehicle, the lower part of the middle of the instrument panel reinforcing beam body 101 is connected to the upper part of the center channel bracket 102, and the lower part of the center channel bracket 102 is connected to the center channel of the floor (not shown in the figure), thereby facilitating the fixing of the instrument panel reinforcing beam assembly.

[0065] 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.

[0066] 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 better improve the overall structural strength and rigidity of the instrument panel reinforcing beam body 101.

[0067] Furthermore, end mounting brackets 103 are provided at both ends of the instrument panel reinforcing beam body 101. The end mounting brackets 103 extend along the vertical direction of the vehicle, and in specific implementations, each end mounting bracket 103 has an extension section. The extension section on each end mounting bracket 103 extends towards the interior side along the horizontal direction of the vehicle, making the shape of both end mounting brackets 103 "L". In practical applications, each end mounting bracket 103 is provided with mounting holes, which facilitates fixing the instrument panel (not shown in the figure) to the end mounting bracket 103.

[0068] 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 2 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.

[0069] Each instrument panel mounting bracket 104 is used to mount the instrument panel. It should be noted that, for ease of overall layout, 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 and meeting the vehicle's lightweight requirements. The specific instrument panel mounting brackets 104 used can be arranged according to actual needs.

[0070] In some of the exemplary implementations, for example Figure 3 and Figure 4As shown, each of the first mounting brackets 2 includes a first horizontal plate 201 and a first vertical plate 202 arranged intersectingly. The first horizontal plate 201 is detachably connected to the instrument panel reinforcing beam body 1 by a first fastener 4. The first vertical plate 202 is provided with a first connecting part 2021 that is connected to the reinforcing beam sub-assembly fixture.

[0071] Here, each first mounting bracket 2 includes an intersecting first horizontal plate 201 and a first vertical plate 202, which increases the rigidity of the first mounting bracket 2. This intersecting arrangement provides stronger resistance to deformation and effectively disperses and bears forces from different directions. The intersecting first horizontal plate 201 and first vertical plate 202 can distribute the forces borne to the instrument panel reinforcing beam body 1 and the reinforcing beam assembly fixture, preventing excessive local stress on the first mounting bracket 2 and thus preventing deformation or damage, thereby improving the overall structural stability of the first mounting bracket 2.

[0072] The first horizontal plate 201 is detachably connected to the instrument panel reinforcing beam body 1 via the first fastener 4, making the installation and removal of the first mounting bracket 2 more convenient and faster. For example, in one embodiment, the first horizontal plate 201 is provided with a through hole, through which the first fastener 4, such as a bolt, passes to connect with the reinforcing beam assembly fixture.

[0073] In a preferred embodiment, each first mounting bracket 2 is fixed to the instrument panel reinforcing beam body 1 by two first fasteners 4, and the two first fasteners 4 are arranged at intervals along the vertical direction of the whole vehicle, which helps to improve the stability and reliability of fixing the instrument panel reinforcing beam body 1 to the reinforcing beam sub-assembly fixture.

[0074] During vehicle manufacturing, the first mounting bracket 2 can be installed or removed at any time according to production needs. The detachable connection also facilitates the replacement and maintenance of the first mounting bracket 2. If the first mounting bracket 2 is damaged or worn during use, only a new first mounting bracket 2 needs to be replaced, without needing to replace the entire dashboard reinforcement beam body 1, thus reducing maintenance costs.

[0075] A first connecting part 2021 is provided on the first longitudinal plate 202 to connect with the reinforcing beam assembly fixture, so that the first mounting bracket 2 can reliably connect with the reinforcing beam assembly fixture. For example, the first connecting part 2021 can be connected to the reinforcing beam assembly fixture by bolts to ensure the strength and reliability of the connection.

[0076] This reliable connection ensures the integrity and stability of the entire dashboard structure. The first mounting bracket 2, as the connecting component between the dashboard reinforcing beam body 1 and the reinforcing beam sub-assembly fixture, directly affects the performance of the entire dashboard structure. If the connection between the first mounting bracket 2 and the reinforcing beam sub-assembly fixture is unreliable, it may cause problems such as dashboard shaking and abnormal noises during driving, affecting driving comfort and safety.

[0077] like Figure 3 and Figure 4 As shown, in some exemplary embodiments, the first connecting portion 2021 includes a first through hole provided on the first longitudinal plate 202, the axial direction of the first through hole being arranged along the left-right direction of the vehicle.

[0078] The left-right direction of the vehicle is usually related to the main structural layout and assembly direction of the vehicle. In the structure above, the first through hole is arranged axially along this direction. During the process of installing the instrument panel reinforcing beam onto the reinforcing beam sub-assembly fixture, it can match the installation direction of the opposite parts such as the mounting pin. This makes it easy for the operator to quickly and accurately pass the mounting pin through the first through hole, realizing the connection and positioning of the first mounting bracket 2 and the reinforcing beam sub-assembly fixture. For example, if the first through hole is a circular hole and the mounting pin is a pin with a circular cross-section, the instrument panel reinforcing beam body 1 can be installed onto the reinforcing beam sub-assembly fixture by inserting the mounting pin into the first through hole.

[0079] In one example, still refer to Figure 3 As shown, a first flange 203 is provided circumferentially around the first through hole. The first flange 203 is equivalent to a reinforcing structure set around the first through hole, which can effectively increase the local strength of the first longitudinal plate 202 at the first through hole. When the mounting pin passes through the first through hole, it will generate a large pressure and shear force on the material around the through hole. The presence of the first flange 203 can disperse these forces, reduce stress concentration on the material at the edge of the first through hole, and prevent problems such as cracks, deformation or even breakage at the first through hole, thereby improving the overall structural reliability and service life of the first mounting bracket 2.

[0080] Continue to refer to Figure 3 As shown, in some exemplary embodiments, at least one of the first horizontal plate 201 and the first vertical plate 202 has a second flange 204 at its edge. For example Figure 3 and Figure 4 The first mounting bracket 2 shown has a second flange 204 on the edges of the first horizontal plate 201 and the second vertical plate 302. This is equivalent to adding an extra support structure to the edges of the first horizontal plate 201 and the first vertical plate 202. When the first horizontal plate 201 or the first vertical plate 202 is subjected to a force perpendicular to the plate surface, the second flange 204 can effectively resist the bending deformation of the plate surface.

[0081] It should be understood that, in addition to providing the second flange 204 on the edges of both the first horizontal plate 201 and the first vertical plate 202, the second flange 204 may also be provided only on the edge of the first horizontal plate 201 or only on the edge of the first vertical plate 202.

[0082] In some exemplary embodiments, at least one of the first longitudinal plates 202 is provided with a weight-reducing hole 2022. For example Figure 3 The first mounting bracket 2 shown has a weight-reducing hole 2022, and Figure 4 The first mounting bracket 2 shown does not have a weight reduction hole 2022.

[0083] By reasonably setting weight-reducing holes 2022 on the first longitudinal plate 202, the amount of material used in the first longitudinal plate 202 can be directly reduced without significantly affecting the structural strength, thereby effectively reducing the overall weight and cost of the first mounting bracket 2.

[0084] In some of these examples, continue to refer to Figure 3 As shown, the edge of the weight-reducing hole 2022 is provided with a third flange 205, which is equivalent to setting a reinforcing structure around the hole, which can effectively improve the local strength of the edge of the weight-reducing hole 2022. When the first longitudinal plate 202 is subjected to external force, the third flange 205 can disperse the stress, reduce stress concentration, and prevent problems such as cracks, deformation or even breakage at the edge of the weight-reducing hole 2022.

[0085] Although the weight-reduction hole 2022 is provided, the presence of the third flange 205 can compensate for the loss of structural stiffness caused by the opening. The third flange 205 cooperates with the main structure of the first longitudinal plate 202 to jointly resist external forces, ensuring that the first mounting bracket 2 has sufficient stiffness to support the instrument panel and related components while meeting the lightweight requirements.

[0086] In some of the exemplary embodiments, at least one of the first longitudinal plates 202 is provided with a first anti-rotation part 2024, which is inserted and connected to a first anti-rotation mating part on the reinforcing beam sub-assembly fixture, thereby preventing the dashboard reinforcing beam body 1 from flipping relative to the reinforcing beam sub-assembly fixture.

[0087] The first anti-rotation part 2024 is inserted and connected to the first anti-rotation mating part on the reinforcing beam sub-assembly fixture. This connection method can restrict the degree of freedom of the instrument panel reinforcing beam body 1 relative to the reinforcing beam sub-assembly fixture in a specific direction. The insertion connection of the first anti-rotation part 2024 can firmly position the instrument panel reinforcing beam body 1 and the reinforcing beam sub-assembly fixture together, preventing them from rotating relative to each other, thereby ensuring the smooth progress of the entire instrument panel reinforcing beam body 1 sub-assembly process.

[0088] For example, in this embodiment, Figure 3 The first mounting bracket 2 shown is provided with a first anti-rotation part 2024, and Figure 4 The first mounting bracket 2 shown does not have a first anti-rotation part 2024. In a specific implementation, as... Figure 3 In the first anti-rotation part 2024, a through hole is provided on the first longitudinal plate 202, into which the pin on the reinforcing beam sub-assembly fixture can be inserted. Since the mounting pin on the reinforcing beam sub-assembly bracket is also inserted into the first through hole, the two cooperate to prevent the instrument panel reinforcing beam body 1 from flipping relative to the reinforcing beam sub-assembly fixture.

[0089] In one example, the two first mounting brackets 2 have different structures, for example... Figure 3 and Figure 4 The two types of first mounting brackets 2 are set in the middle. Figure 3 The first mounting bracket 2 shown is installed on the right side of the instrument panel reinforcing beam body 1. Figure 4 The first mounting bracket 2 shown is installed on the left side of the instrument panel reinforcing beam body 1. It should be understood that their positions can be interchanged. In another example, both first mounting brackets 2 are... Figure 3 The structure shown is also feasible.

[0090] For example Figure 5 and Figure 6 As shown, in some exemplary embodiments, each second mounting bracket 3 includes intersecting second horizontal plates 301 and second vertical plates 302. The second horizontal plate 301 is detachably connected to the instrument panel reinforcing beam body 1 by a second fastener 5, and a positioning structure is provided between the second horizontal plate 301 and the instrument panel reinforcing beam body 1, which can define the position of the second horizontal plate 301 on the instrument panel reinforcing beam body 1. Each second vertical plate 302 is provided with a second connecting portion 3021 that connects to the reinforcing beam assembly fixture.

[0091] In the above structure, each second mounting bracket 3 includes an intersecting second horizontal plate 301 and a second vertical plate 302, which increases the rigidity of the second mounting bracket 3. This intersecting arrangement provides stronger resistance to deformation and effectively disperses and bears forces from different directions. The intersecting second horizontal plate 301 and second vertical plate 302 can distribute the forces borne to the instrument panel reinforcing beam body 1 and the reinforcing beam assembly fixture, preventing excessive local stress on the second mounting bracket 3 and thus preventing deformation or damage, thereby improving the overall structural stability of the second mounting bracket 3.

[0092] The second horizontal plate 301 is detachably connected to the instrument panel reinforcing beam body 1 via a second fastener 5. This connection method ensures both the strength of the connection and facilitates disassembly and installation. In one example, the second horizontal plate 301 is provided with a through hole. The second fastener 5, such as a bolt, passes through the through hole and is connected to the instrument panel reinforcing beam body 1, thereby fixing the second mounting bracket 3 to the instrument panel reinforcing beam body 1.

[0093] In one example, a positioning structure is provided between the second horizontal plate 301 and the instrument panel reinforcing beam body 1, which can define the position of the second horizontal plate 301 on the instrument panel reinforcing beam body 1. The positioning structure can ensure the accurate position of the second mounting bracket 3 during installation, avoiding structural interference or performance degradation caused by installation deviation.

[0094] For example, the second horizontal plate 301 is provided with a positioning hole 3012, and the reinforcing beam assembly tooling is provided with a positioning pin. By inserting the positioning pin into the positioning hole 3012, the reliability of fixing the second mounting bracket 3 to the instrument panel reinforcing beam body 1 can be improved. This positioning structure cooperates with the second fastener 5 to prevent the second mounting bracket 3 from rotating relative to the instrument panel reinforcing beam body 1.

[0095] In some examples, the two second mounting brackets 3 have the same structure, so the designer only needs to do the design work once, without having to design different structures and dimensions for each bracket. This can greatly reduce design time and workload, and lower design costs.

[0096] The two second mounting brackets 3 adopt the same structure, which means that the same set of molds can be used to produce both second mounting brackets 3. Since the manufacturing and maintenance costs of molds are high, the use of universal molds can significantly reduce mold costs, while reducing mold replacement and debugging time and improving production efficiency. The identical structure of the two second mounting brackets 3 also makes inventory management more convenient.

[0097] In some of these exemplary implementations, reference continues to be made to... Figure 5 and Figure 6 As shown, the second connecting part 3021 includes a second through hole provided on the second longitudinal plate 302, and the axial direction of the second through hole is arranged along the left and right direction of the whole vehicle.

[0098] When connecting the second longitudinal plate 302 to the reinforcing beam assembly fixture, the mounting pin on the reinforcing beam assembly fixture can pass through the second through hole, thereby fixing the dashboard panel reinforcing beam 1 to the reinforcing beam assembly fixture. Since the second through hole is axially arranged along the left-right direction of the vehicle, this arrangement meets the common connection layout requirements in automotive structures.

[0099] In one example, the edge of the second via is provided with a fourth flange 303, which is equivalent to forming a reinforcing structure around the via. When the mounting pin is inserted into the second via, the fourth flange 303 can disperse some of the stress, reduce stress concentration, and thus improve the local strength of the edge of the second via.

[0100] In some exemplary embodiments, at least one of the second horizontal plate 301 and the second vertical plate 302 has a fifth flange 304 on its edge, which can increase the structural strength and rigidity of the second mounting bracket 3, thereby improving the ability of the second mounting bracket 3 to resist bending deformation.

[0101] For example, in one embodiment, both the edges of the second horizontal plate 301 and the second vertical plate 302 are provided with a fifth flange 304, which can effectively improve the structural strength and rigidity of the second mounting bracket 3. It should be understood that it is feasible to provide the fifth flange 304 only on the edge of the second horizontal plate 301 or only on the edge of the second vertical plate 302.

[0102] In some exemplary embodiments, the second longitudinal plate 302 is provided with a second anti-rotation part 3022, which is connected to a second anti-rotation mating part on the reinforcing beam assembly fixture, thereby preventing the instrument panel reinforcing beam body 1 from flipping relative to the reinforcing beam assembly fixture.

[0103] In one example, the aforementioned second through hole is an irregularly shaped hole, with a cross-sectional shape such as a combination of semi-circular and square, or a square, etc., so that the second through hole also serves as the function and role of the second anti-rotation part 3022. It should be understood that, in addition to being formed by the aforementioned second through hole, the second anti-rotation part 3022 can also be provided with a through hole on the second longitudinal plate 302. By inserting a pin on the reinforcing beam assembly tooling into the through hole and cooperating with the mounting pin inserted into the second through hole, it can prevent the instrument panel reinforcing beam body 1 from flipping over.

[0104] Continue to combine Figures 1 to 3 As shown, in some of the exemplary embodiments, it is worth noting that, for the dashboard reinforcement beam assembly of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 6 shown.

[0105] The instrument panel reinforcement beam assembly includes an instrument panel reinforcement beam body 1 and a first mounting bracket 2 and a second mounting bracket 3 detachably connected to the instrument panel reinforcement beam body 1. Along the left-right direction of the vehicle, the instrument panel reinforcement beam body 1 is provided with the first mounting bracket 2 and the second mounting bracket 3 near both ends, with the first mounting bracket 2 and the second mounting bracket 3 at each end respectively positioned on the front and rear sides of the instrument panel reinforcement beam body 1. The first mounting bracket 2 is used to mount the instrument panel reinforcement beam body 1 onto a reinforcement beam sub-assembly fixture, and the second mounting bracket 3 is used to mount the instrument panel reinforcement beam body 1 onto a reinforcement beam final assembly fixture.

[0106] The two first mounting brackets 2 have different structures. Each first mounting bracket 2 includes a first horizontal plate 201 and a first vertical plate 202 arranged intersectingly. The first horizontal plate 201 is detachably connected to the instrument panel reinforcing beam body 1 by bolts. The first vertical plate 202 is provided with a circular first through hole for connecting with the reinforcing beam sub-assembly fixture. The axial direction of the first through hole is arranged along the left and right direction of the whole vehicle. The circumferential direction of the first through hole is provided with a first flange 203.

[0107] The edges of the first horizontal plate 201 and the first vertical plate 202 are provided with second flanges 204. The first vertical plate 202 of the first mounting bracket 2 is provided with a weight reduction hole 2022 and a first anti-rotation part 2024. The edge of the weight reduction hole 2022 is provided with a third flange 205.

[0108] The two second mounting brackets 3 have the same structure. Each second mounting bracket 3 includes a second horizontal plate 301 and a second vertical plate 302 arranged intersectingly. The second horizontal plate 301 is detachably connected to the instrument panel reinforcing beam body 1 by bolts, and has a through hole for positioning on the second horizontal plate 301. Each second vertical plate 302 has an irregularly shaped second through hole for connecting with the reinforcing beam sub-assembly fixture.

[0109] The second through hole is arranged axially along the left-right direction of the whole vehicle, and the edge of the second through hole is provided with a fourth flange 303. The edges of the second horizontal plate 301 and the second vertical plate 302 are both provided with a fifth flange 304, and each second vertical plate 302 is provided with a second anti-rotation part 3022.

[0110] In the above preferred embodiment, the instrument panel reinforcing beam assembly adopts the above design. During the sub-assembly of the instrument panel reinforcing beam assembly, the instrument panel reinforcing beam body 1 is installed onto the reinforcing beam sub-assembly fixture via two first mounting brackets 2, and then the instrument panel, air conditioner, steering column, wiring harness, fragrance and other components are installed. The circular pins arranged on the reinforcing beam sub-assembly fixture can be inserted into the circular through holes on the first mounting brackets 2 to support the instrument panel reinforcing beam body 1, facilitating the installation of wiring harness, instrument panel, air conditioner, steering column and other components.

[0111] When installing the dashboard reinforcement beam assembly onto the vehicle body, the dashboard reinforcement beam assembly is first installed onto the reinforcement beam assembly fixture via the second mounting bracket 3. The irregularly shaped pins on the reinforcement beam assembly fixture can be inserted into the irregularly shaped holes on the second mounting bracket 3, making it convenient to lift the dashboard reinforcement beam assembly up and then install it onto the vehicle body. After that, each first mounting bracket 2 and each second mounting bracket 3 can be removed.

[0112] Removing the first mounting bracket 2 and the second mounting bracket 3 increases the design flexibility of the instrument panel reinforcing beam body 1, facilitating subsequent maintenance and upgrades. The detachable design of the first mounting bracket 2 and the second mounting bracket 3 also improves supply chain management and reduces inventory and logistics costs.

[0113] To ensure that each first mounting bracket 2 and each second mounting bracket 3 can be reused after disassembly, in one example, each first mounting bracket 2 and each second mounting bracket 3 is made of 510L steel, which can improve the strength and durability of each mounting bracket.

[0114] Taking a material thickness of 3mm for each mounting bracket as an example, the weight of the first mounting bracket 2 on the left is 0.157kg, the weight of the first mounting bracket 2 on the right is 0.359kg, and the weight of each of the two second mounting brackets 3 is 0.145kg. After removing the above four brackets with bolts, the weight of the instrument panel reinforcement beam assembly can be reduced by 0.5kg compared to the previous solution, saving 12 yuan in costs.

[0115] An embodiment of the second aspect of this application provides a vehicle equipped with the instrument panel reinforcement beam assembly described above.

[0116] In this embodiment, the vehicle utilizes the instrument panel reinforcement beam assembly described above. Since both the first mounting bracket 2 and the second mounting bracket 3 are detachable, the first mounting bracket 2 and the second mounting bracket 3 can be removed after the instrument panel reinforcement beam assembly is installed on the vehicle body. This reduces the overall weight of the vehicle and helps to improve its fuel economy.

[0117] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
