Technical Field

[0001] This application relates to the field of vehicle body technology, and in particular to an instrument panel reinforcement beam assembly and vehicle. Background Technology

[0002] As one of the skeletal structures at the front of the vehicle body, the instrument panel reinforcement beam not only supports the instrument panel but also serves as the mounting base for components such as the steering column. The instrument panel reinforcement beam and the steering column mounting bracket mounted on it together constitute the instrument panel reinforcement beam assembly.

[0003] Currently, steering column mounting brackets are typically attached to the dashboard reinforcement beam and fixed together by welding or bolting. This setup still suffers from limitations such as limited connection strength between the dashboard reinforcement beam and the steering column mounting bracket, making it difficult to effectively improve the stability of the steering column installation and thus hindering the improvement of the overall vehicle quality. Utility Model Content

[0004] In view of this, this application aims to propose a dashboard reinforcement beam assembly to improve the overall quality of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: An instrument panel reinforcement beam assembly includes an instrument panel reinforcement beam and a steering column mounting bracket disposed on the instrument panel reinforcement beam; The instrument panel reinforcing beam has a reinforcing beam body with a "C" shaped cross-section, and a connecting groove is provided on one side of the steering column mounting bracket; The main body of the reinforcing beam is connected in the connecting groove, and the opening on the side of the main body of the reinforcing beam is blocked by the steering column mounting bracket, so that a ring structure is formed between the main body of the reinforcing beam and the steering column mounting bracket.

[0006] Furthermore, the main body of the reinforcing beam is made of steel sheet metal, and a plastic bracket is injection molded on the main body of the reinforcing beam; The plastic bracket includes a body connecting bracket provided at both ends of the main body of the reinforcing beam, and a body connecting point is provided on each of the two body connecting brackets.

[0007] Furthermore, the plastic bracket includes an inner reinforcing bracket disposed inside the main body of the reinforcing beam, and an outer reinforcing bracket disposed outside the main body of the reinforcing beam. Both the inner reinforcing bracket and the outer reinforcing bracket are arranged along the length of the main body of the reinforcing beam and are connected to the vehicle body connecting brackets at both ends.

[0008] Further, each of the inner reinforcing support and the outer reinforcing support comprises a transverse portion extending along the length direction of the reinforcing beam main body, and a vertical portion interwoven and connected with the transverse portion; The transverse portion is connected to the vehicle body connection supports at both ends, and a plurality of the vertical portions are arranged at intervals along the length direction of the reinforcing beam main body.

[0009] Further, the reinforcing beam main body is provided with a plurality of through holes, and the plastic support comprises connecting portions embedded in the respective through holes; The inner reinforcing support and the outer reinforcing support are connected together through the connecting portions.

[0010] Further, positions of the inner reinforcing support and the outer reinforcing support close to the vehicle body connection supports at the respective ends are both provided with reinforcing portions; The reinforcing portions are arranged obliquely relative to the transverse portion and the vertical portion, and a plurality of the reinforcing portions are arranged, and form a "star" shaped structure together with the transverse portion and the vertical portion.

[0011] Further, the plastic support comprises a plurality of instrument panel mounting supports connected to the reinforcing beam main body, and the instrument panel mounting supports are provided with instrument panel mounting points; and / or, The plastic support comprises a middle tunnel connection support with a top connected to the reinforcing beam main body, and a bottom of the middle tunnel connection support is provided with a middle tunnel connection point; and / or, Both the vehicle body connection supports at the two ends are provided with an assembly tool support and a module sub-assembly tool support, the assembly tool support is integrally formed with the vehicle body connection support, and the module sub-assembly tool support adopts a steel sheet metal structure.

[0012] Further, the steering column mounting support is formed by casting, and the steering column mounting support has a frame portion, and a housing portion connected to the inner side of the frame portion; One side of the frame portion is formed with the connection groove, the housing portion is arranged to bulge downward relative to the frame portion, and the frame portion and the housing portion are respectively provided with steering column mounting points.

[0013] Further, reinforcing ribs are arranged on both the frame portion and the housing portion, and part of the reinforcing ribs on the frame portion and the housing portion are connected together; and / or, At least one of the frame portion and the housing portion is provided with a weight reduction hole.

[0014] Compared with the related art, the present application has the following advantages: (1) The instrument panel reinforcing beam assembly described in this application has a reinforcing beam body with a "C" shaped cross section and a connecting groove on one side of the steering column mounting bracket. The reinforcing beam body is connected in the connecting groove, and the opening on the side of the reinforcing beam body is blocked by the steering column mounting bracket, so that a ring structure is formed between the reinforcing beam body and the steering column mounting bracket. By utilizing the setting of the reinforcing beam body in the connecting groove on the steering column mounting bracket and the high strength of the ring structure, the connection strength between the steering column mounting bracket and the instrument panel reinforcing beam can be increased, the stability of the steering column installation can be improved, and the overall quality of the vehicle can be improved.

[0015] (2) The main body of the reinforcing beam is made of steel sheet metal, and a plastic bracket including the body connecting brackets at both ends is injection molded on the main body of the reinforcing beam. This combines the high strength of the steel reinforcing beam and the lightweight characteristics of the plastic bracket. While meeting the overall rigidity requirements of the instrument panel reinforcing beam, the overall weight of the instrument panel reinforcing beam is reduced, which helps to improve the overall quality of the instrument panel reinforcing beam.

[0016] (3) The plastic bracket includes reinforcing brackets located on the inner and outer sides of the main body of the reinforcing beam, and the inner and outer reinforcing brackets are arranged along the length of the main body of the reinforcing beam and connected to the body connecting brackets at both ends. The plastic reinforcing brackets that form a full-length coverage of the inner and outer sides of the main body of the reinforcing beam can further increase the structural strength of the main body of the instrument panel reinforcing beam, and can also increase the stability of the body connecting brackets at both ends on the main body of the reinforcing beam, which is conducive to improving the setting effect of the plastic brackets.

[0017] (4) Both the inner and outer reinforcing brackets include a transverse portion extending along the length of the main body of the reinforcing beam, and multiple vertical portions arranged at intervals along the length of the main body of the reinforcing beam. The vertical portions are interwoven and connected with the transverse portions. This not only makes the structure simple and easy to design and form, but also allows both the inner and outer reinforcing brackets to have a good structural reinforcement effect, which is conducive to ensuring the reinforcement effect of the inner and outer reinforcing brackets on the main structure of the instrument panel reinforcing beam.

[0018] (5) By setting through holes on the main body of the reinforcing beam, the plastic bracket includes a connecting part embedded in the through hole, and the inner reinforcing bracket and the outer reinforcing bracket are connected through the connecting part in the through hole. On the one hand, the plastic bracket can be used to increase the connection force between the inner and outer reinforcing brackets and the steel reinforcing beam main body by using the through hole in the main body of the reinforcing beam, which can improve the stability of the inner and outer brackets on the main body of the reinforcing beam. On the other hand, the through hole on the main body of the reinforcing beam can also be used to reduce the weight of the steel reinforcing beam main body, which is beneficial to the lightweighting of the instrument panel reinforcing beam.

[0019] (6) Multiple reinforcing parts are arranged at an angle near the body connecting brackets at each end of the inner and outer reinforcing brackets, and the multiple reinforcing parts, together with the horizontal and vertical parts, form a "rice" shaped structure. The higher strength of the "rice" shaped structure can be used to fully improve the rigidity of key positions on the instrument panel reinforcing beam, which helps to further improve the stability of the two end body connecting brackets at the ends of the reinforcing beam and improves the reliability of the instrument panel reinforcing beam assembly in the body.

[0020] (7) The plastic bracket includes an instrument panel mounting bracket with an instrument panel mounting point, which facilitates the installation and arrangement of the instrument panel on the instrument panel reinforcement beam. It also takes advantage of the fact that the instrument panel mounting bracket is made of plastic material, which is conducive to reducing the weight of the instrument panel reinforcement beam and achieving the lightweight design of the vehicle body.

[0021] The plastic bracket includes a center channel connecting bracket with a center channel connection point. By utilizing the plastic material of the center channel connecting bracket, the instrument panel reinforcement beam can be connected to the center channel of the front floor, thereby reducing the weight of the instrument panel reinforcement beam and contributing to the lightweight design of the vehicle body.

[0022] By setting up final assembly tooling brackets and module assembly tooling brackets on the vehicle body connecting brackets at each end, the assembly operation of the vehicle body can be facilitated, which helps to improve the assembly efficiency of the vehicle body. At the same time, the final assembly tooling bracket is integrally formed on the vehicle body connecting bracket, which can help reduce the design and manufacturing cost of the final assembly tooling bracket. The module assembly tooling bracket adopts a steel sheet metal structure, which can ensure the rigidity and strength of the module assembly tooling bracket and ensure the reliability of its use.

[0023] (8) The steering column mounting bracket is cast, which not only facilitates its preparation and helps to reduce the manufacturing cost of the steering column mounting bracket, but also ensures the structural strength of the steering column mounting bracket, which helps to improve the stability of the steering column installation. At the same time, the steering column mounting bracket includes a frame part and a downwardly bulging shell part. The frame structure and the bulging structure have greater strength, which increases the rigidity of the steering column mounting bracket itself and helps to improve the stability of the steering column installation.

[0024] (9) Reinforcing ribs are provided on the frame and shell parts of the steering column mounting bracket, and some of the reinforcing ribs on the frame and shell parts are connected together. The structural reinforcement effect of the reinforcing ribs can be used to increase the structural strength of the frame and shell parts, and at the same time, the connection strength between the frame and shell parts can be increased. This helps to further increase the rigidity of the steering column mounting bracket and is conducive to improving the stability of the steering column installation.

[0025] By providing weight-reduction holes in the frame and housing sections, the weight of the steering column mounting bracket can be reduced, which is beneficial for the lightweighting of the instrument panel reinforcement beam assembly and the vehicle body on which the instrument panel reinforcement beam assembly is installed.

[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 has the same advantages as the aforementioned dashboard reinforcement beam assembly compared to the prior art, and will not be repeated here. Attached Figure Description

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.

[0032] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0033] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] 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.

[0035] An embodiment of the first aspect of this application provides an instrument panel reinforcement beam assembly, which includes a steering column mounting bracket. The instrument panel reinforcement beam assembly of this embodiment, through its innovative structural design, helps to improve the overall quality of the vehicle.

[0036] In related technologies, for instrument panel reinforcement beam assemblies that integrate steering column mounting brackets, the instrument panel reinforcement beam is generally a tubular beam, the steering column mounting bracket is generally a sheet metal welded structure, and the steering column mounting bracket is usually overlapped on the instrument panel reinforcement beam and fixed together by welding or screwing.

[0037] The existing connection between the steering column mounting bracket and the instrument panel reinforcement beam, although it enables the steering column mounting bracket to be installed on the instrument panel reinforcement beam, still has shortcomings such as limited connection strength between the instrument panel reinforcement beam and the steering column mounting bracket. It is difficult to effectively improve the stability of the steering column installation, which can easily cause the steering column and the steering wheel on it to vibrate, affecting the driving experience and hindering the improvement of the overall quality of the vehicle.

[0038] In view of this, in order to overcome the shortcomings of the related technology, the dashboard reinforcement beam assembly of this embodiment combines... Figures 1 to 11 As shown, the overall design includes an instrument panel reinforcing beam 1 and a steering column mounting bracket 2 mounted on the instrument panel reinforcing beam 1.

[0039] The instrument panel reinforcing beam 1 has a reinforcing beam body 11 with a "C" shaped cross-section, and a connecting groove 2a is also provided on one side of the steering column mounting bracket 2. The reinforcing beam body 11 is connected in the connecting groove 2a, and the opening on the side of the reinforcing beam body 11 is blocked by the steering column mounting bracket 2, so that a ring structure S is formed between the reinforcing beam body 11 and the steering column mounting bracket 2.

[0040] Therefore, with the above configuration, by making the instrument panel reinforcing beam 1 have a reinforcing beam body 11 with a "C" shaped cross section, and providing a connecting groove 2a on one side of the steering column mounting bracket 2, and with the reinforcing beam body 11 connected in the connecting groove 2a, the opening on the side of the reinforcing beam body 11 is blocked by the steering column mounting bracket 2, thereby forming an annular structure S between the reinforcing beam body 11 and the steering column mounting bracket 2. Thus, this embodiment can utilize the setting of the reinforcing beam body 11 in the connecting groove 2a on the steering column mounting bracket 2, as well as the high strength of the annular structure, to increase the connection strength between the steering column mounting bracket 2 and the instrument panel reinforcing beam 1, thereby improving the stability of the steering column installation, which is beneficial to improving the driving experience of the vehicle, and thus achieving the effect of improving the overall quality of the vehicle.

[0041] Based on the above overall introduction, specifically, it is worth noting that the annular structure S formed by the instrument panel reinforcing beam 1 with a "C"-shaped cross-section and the steering column mounting bracket 2 can be as follows: Figure 2 As shown in the dashed box, the ring structure S can still be as follows: Figure 2 The ring structure shown is roughly square; however, besides being square, it can also be other shapes depending on the cross-sectional shape of the instrument panel reinforcing beam 1 and the shape of the portion of the steering column mounting bracket 2 used to seal the side opening of the instrument panel reinforcing beam 1. There are no limitations on this. The key is that it can form a stable ring structure S while ensuring a reliable connection between the steering column mounting bracket 2 and the reinforcing beam body 11, and can increase the connection strength between the steering column mounting bracket 2 and the instrument panel reinforcing beam 1.

[0042] In this embodiment, we continue to combine Figures 3 to 9 As shown, in some exemplary embodiments, the reinforcing beam body 11 may be made of steel sheet metal, and a plastic bracket 12 is also injection molded onto the reinforcing beam body 11.

[0043] The plastic bracket 12 includes a body connecting bracket 121 respectively set at both ends of the reinforcing beam body 11, and a body connection point 121a is also set on the body connecting bracket 121 at both ends.

[0044] It is understandable that by making the reinforcing beam body 11, which is the main structure of the instrument panel reinforcing beam 1, a steel sheet metal is used, and a plastic bracket 12 including the body-mounted brackets at both ends is injection molded on the reinforcing beam body 11, this embodiment can combine the high strength of the steel reinforcing beam body 11 and the lightweight characteristics of the plastic bracket 12. While meeting the overall rigidity requirements of the instrument panel reinforcing beam 1, the overall weight of the instrument panel reinforcing beam 1 is reduced, thereby helping to improve the overall quality of the instrument panel reinforcing beam 1.

[0045] In practical implementation, it is worth noting that the reinforcing beam body 11, made of steel sheet metal, can generally be manufactured by stamping to obtain a "C" shaped cross-section. For the plastic bracket 12 injection molded onto the reinforcing beam body 11, during injection molding, the reinforcing beam body 11 is placed in the injection mold, molten plastic is injected into the mold, and the plastic bracket 12 is formed by insert injection molding.

[0046] Furthermore, the aforementioned body connecting brackets 121 located at both ends of the reinforcing beam body 11 are typically connected to the A-pillars on the left and right sides of the vehicle body. The design of each body connecting bracket 121 can be matched to the connection position on the A-pillar. Meanwhile, the body connection points 121a located on the body connecting brackets 121 can generally be hole-like structures formed on the body connecting brackets 121. To ensure the reliability of the connection of the body connecting brackets 121 within the vehicle body, preferably, metal bushings can be pre-embedded at the body connection points 121a on the body connecting brackets 121 to increase the rigidity at the body connection points 121a.

[0047] It should be noted that, in addition to pre-embedding a metal bushing at the body connection point 121a on the body connection bracket 121 to improve the rigidity of the body connection point 121a, in this embodiment, for other connection points (such as the central channel connection point 125a) or mounting points (such as the instrument panel mounting point 124a) on the plastic bracket 12, a metal bushing can also be pre-embedded at the connection point or mounting point to achieve the same effect of improving the rigidity of the connection point or mounting point.

[0048] In some exemplary embodiments of this invention, given that the cross-section of the reinforcing beam body 11 is "C" shaped, the aforementioned plastic bracket 12 may include, for example, an inner reinforcing bracket 123 disposed inside the reinforcing beam body 11, and an outer reinforcing bracket 122 disposed outside the reinforcing beam body 11.

[0049] The inner reinforcing bracket 123 and the outer reinforcing bracket 122 are both arranged along the length of the main body of the reinforcing beam 11, that is, in the left and right direction of the whole vehicle, and the inner reinforcing bracket 123 and the outer reinforcing bracket 122 are also connected to the body connecting brackets 121 at both ends.

[0050] At this time, by making the plastic bracket 12 include reinforcing brackets respectively disposed on the inner and outer sides of the reinforcing beam body 11, and making the inner and outer reinforcing brackets arranged along the length direction of the reinforcing beam body 11 and connected to the vehicle body connecting brackets 121 at both ends, it can be understood that this embodiment can further increase the structural strength of the main structure of the instrument panel reinforcing beam 1 by utilizing the plastic reinforcing brackets that form a full-length coverage of the inner and outer sides of the reinforcing beam body 11. At the same time, it can obviously also increase the stability of the vehicle body connecting brackets 121 at both ends on the reinforcing beam body 11, which is beneficial to improving the setting effect of the plastic bracket 12.

[0051] In specific implementation, it is worth noting that the inner reinforcing bracket 123 and the outer reinforcing bracket 122, which are respectively set on the inner and outer sides of the reinforcing beam body 11, can adopt any suitable structure arranged along the length direction of the reinforcing beam body 11. There are no restrictions on them, as long as they can facilitate the forming of the inner reinforcing bracket 123 and the outer reinforcing bracket 122 and can strengthen the structure of the instrument panel reinforcing beam 1.

[0052] Furthermore, as an example of the specific structure of the aforementioned inner reinforcing bracket 123 and outer reinforcing bracket 122, please refer to... Figures 3 to 7 As shown, in some exemplary embodiments, the inner reinforcing bracket 123 and the outer reinforcing bracket 122 may each include, for example, a transverse portion 12a extending along the length of the reinforcing beam body 11, and a vertical portion 12b interwoven and connected with the transverse portion 12a.

[0053] The horizontal portion 12a is connected to the vehicle body connecting brackets 121 at both ends, and the vertical portion 12b consists of multiple portions spaced along the length of the reinforcing beam body 11. Since the cross-section of the reinforcing beam body 11 is "C" shaped, for example, the horizontal portion 12a can be set at the middle and upper and lower edges of the reinforcing beam body 11. Meanwhile, each vertical portion 12b in the inner reinforcing bracket 123 can be connected to the inner wall surface of each side of the reinforcing beam body 11, and each vertical portion 12b in the outer reinforcing bracket 122 can be connected to the outer wall surface of each side of the reinforcing beam body 11.

[0054] It is understandable that by making both the inner reinforcing bracket 123 and the outer reinforcing bracket 122 include a transverse portion 12a extending along the length direction of the reinforcing beam body 11, and multiple vertical portions 12b arranged at intervals along the length direction of the reinforcing beam body 11, and making each vertical portion 12b intertwined with the transverse portion 12a, it not only has the advantages of simple structure and easy design and molding, but also enables both the inner reinforcing bracket 123 and the outer reinforcing bracket 122 to have a good structural reinforcement effect, which is conducive to ensuring the reinforcement effect of the inner and outer reinforcing brackets on the main structure of the instrument panel reinforcing beam 1.

[0055] Additionally, in specific implementation, it is worth noting that, given that the inner reinforcing bracket 123 is located inside the main body of the reinforcing beam 11, therefore, reference should be made to... Figure 5 and Figure 7 As shown, the horizontal portion 12a and the vertical portion 12b of the inner reinforcing bracket 123 can both have larger dimensions than the horizontal portion 12a and the vertical portion 12b of the outer reinforcing bracket 122.

[0056] This results in the transverse portion 12a and the vertical portion 12b located inside the main body 11 of the reinforcing beam having larger dimensions. Obviously, this can provide good support for the main body 11 of the reinforcing beam without affecting the arrangement of the instrument panel reinforcing beam 1, and helps to better increase the overall rigidity of the instrument panel reinforcing beam 1.

[0057] In this embodiment, we continue to combine Figure 8 and Figure 9 As shown, in some exemplary embodiments, the reinforcing beam body 11 may be provided with a plurality of through holes 11a, and the plastic bracket 12 includes a connecting portion 12c embedded in each through hole 11a, while the inner reinforcing bracket 123 and the outer reinforcing bracket 122 are also connected together through the connecting portion 12c embedded in the through holes 11a.

[0058] Therefore, by providing a through hole 11a on the reinforcing beam body 11, the plastic bracket 12 includes a connecting portion 12c embedded in the through hole 11a, and the inner reinforcing bracket 123 and the outer reinforcing bracket are connected through the connecting portion 12c in the through hole 11a. It can be understood that, on the one hand, this embodiment can utilize the permeation of the plastic bracket 12 in the through hole 11a on the reinforcing beam body 11 to increase the connection force between the inner and outer reinforcing brackets in the plastic bracket 12 and the steel reinforcing beam body 11, thereby improving the stability of the inner and outer brackets on the reinforcing beam body 11.

[0059] On the other hand, based on the through hole 11a opened on the steel reinforcing beam body 11 and the plastic embedded in the through hole 11a, this embodiment can also reduce the weight of the steel reinforcing beam body 11 by using the through hole 11a on the reinforcing beam body 11, thereby facilitating the lightweight design of the instrument panel reinforcing beam 1.

[0060] In specific implementation, it is worth noting that the aforementioned through holes 11a can generally be regularly arranged on the main body 11 of the reinforcing beam. Preferably, through holes 11a can be provided respectively corresponding to the horizontal part 12a and the vertical part 12b in the inner and outer reinforcing brackets, so that the horizontal part 12a in the inner and outer reinforcing brackets can be connected through the corresponding connecting part 12c, and the vertical part 12b in the inner and outer reinforcing brackets can also be connected through the corresponding connecting part 12c.

[0061] In addition, the above-mentioned through holes 11a are generally designed as round holes, so as to avoid stress concentration positions when a plurality of through holes 11a are provided, and reduce the adverse effect on the structural performance of the reinforcing beam main body 11.

[0062] At the same time, in some other embodiments, in addition to the above-mentioned through holes 11a, further, in this embodiment, for example, elongated holes 11b and triangular holes 11c may also be provided on the reinforcing beam main body 11. A plurality of elongated holes 11b may be arranged at intervals in the length direction of the reinforcing beam main body 11, and a triangular hole 11c may be provided near each of the two ends of the reinforcing beam main body 11. Based on the arrangement of the respective elongated holes 11b and triangular holes 11c, the plastic bracket 12 may also have connection structures located in the elongated holes 11b and the triangular holes 11c, which also enables the reinforcing brackets on the inner and outer sides of the reinforcing beam main body 11 to be connected through the connection structures.

[0063] In this embodiment, still in conjunction with Figure 5 and Figure 7 as shown, on the basis of including the above-mentioned transverse portion 12a and vertical portion 12b, in some exemplary embodiments, the inner reinforcing bracket 123 and the outer reinforcing bracket 122 located on the inner and outer sides of the reinforcing beam main body 11 may also be provided with reinforcing portions 12d, for example.

[0064] Wherein, the above-mentioned reinforcing portions 12d are respectively provided at positions in the inner reinforcing bracket 123 and the outer reinforcing bracket 122 that are close to the respective end vehicle body connection brackets 121. In addition, there are a plurality of reinforcing portions 12d, and each reinforcing portion 12d is arranged obliquely relative to the transverse portion 12a and the vertical portion 12b, such that the reinforcing portion 12d can form a "star" shaped structure with the transverse portion 12a and the vertical portion 12b at the position where it is located.

[0065] In this case, a plurality of obliquely arranged reinforcing portions 12d are respectively provided at positions of the inner reinforcing bracket 123 and the outer reinforcing bracket 122 close to the respective end vehicle body connection brackets 121, and the plurality of reinforcing portions 12d, the transverse portion 12a and the vertical portion 12b form a "star" shaped structure. It can be understood that this embodiment can take advantage of the higher strength of the "star" shaped structure to fully improve the rigidity and strength of key positions on the instrument panel reinforcing beam 1, thereby helping to further improve the stability of the arrangement of the two end vehicle body connection brackets at the ends of the reinforcing beam main body 11, and is beneficial to improving the reliability of the arrangement of the instrument panel reinforcing beam assembly in the vehicle body.

[0066] In specific implementation, it is worth noting that the "meter"-shaped structures formed in the inner reinforcing supports 123 near the body connection brackets 121 at each end may generally be multiple (e.g., two) arranged at intervals along the length direction of the reinforcing beam main body 11, while the "meter"-shaped structures formed in the outer reinforcing supports 122 near the body connection brackets 121 at each end may be only one. Of course, in addition to the above quantities, the "meter"-shaped structures formed in the inner reinforcing supports 123 and the outer reinforcing supports 122 near the body connection brackets 121 at each end may also be of other quantities, as long as they are convenient for forming and can achieve good structural reinforcing effects.

[0067] In addition, based on the aforementioned arrangement that the long hole 11b and the triangular hole 11c can be provided on the reinforcing beam main body 11, as a preferred implementation form, in this embodiment, for example, the "meter"-shaped structures formed in the inner reinforcing supports 123 and the outer reinforcing supports 122 can be correspondingly aligned with the long holes 11b or the triangular holes 11c. In this way, by taking advantage of the large cross-section characteristics of the long holes 11b and the triangular holes 11c, the connection strength between the "meter"-shaped structures in the inner and outer reinforcing supports can obviously be increased.

[0068] In addition, it should also be pointed out that in addition to forming "meter"-shaped structures in the inner reinforcing supports 123 and the outer reinforcing supports 122 to increase the rigidity and strength of key positions on the instrument panel reinforcing beam 1, by referring to this reinforcing manner, positions such as the body connection points 121a on the body connection brackets 121 can also be provided with "meter"-shaped reinforcing structures, so as to further improve the rigidity and strength of the connection points or mounting points on the plastic bracket 12, and ensure the connection stability between the instrument panel reinforcing beam assembly and surrounding components.

[0069] In this embodiment, in some exemplary implementation forms, the above-mentioned plastic bracket 12 may, for example, include a plurality of instrument panel mounting brackets 124 connected to the reinforcing beam main body 11, and instrument panel mounting points 124a are provided on the instrument panel mounting brackets 124.

[0070] At this time, making the plastic bracket 12 include the instrument panel mounting brackets 124 provided with the instrument panel mounting points 124a can facilitate the installation and arrangement of the instrument panel on the instrument panel reinforcing beam 1, and can also take advantage of the feature that the instrument panel mounting brackets 124 are made of plastic, which is beneficial to reducing the weight of the instrument panel reinforcing beam 1 and realizing the lightweight design of the vehicle body.

[0071] In this embodiment, in some exemplary implementation forms, the above-mentioned plastic bracket 12 may, for example, include a middle tunnel connection bracket 125 whose top is connected to the reinforcing beam main body 11, and a middle tunnel connection point 125a is provided at the bottom of the middle tunnel connection bracket 125.

[0072] At this time, the plastic bracket 12 includes a center channel connecting bracket 125 with a center channel connection point 125a. On the basis of connecting the instrument panel reinforcing beam 1 to the center channel of the front floor, the center channel connecting bracket 125 is made of plastic, which can reduce the weight of the instrument panel reinforcing beam 1, so as to facilitate the lightweight design of the vehicle body.

[0073] In this embodiment, in some exemplary implementations, the vehicle body connecting brackets 121 at both ends can be provided with a final assembly tooling bracket 126 and a module sub-assembly tooling bracket 127, and the final assembly tooling bracket 126 is integrally formed with the vehicle body connecting bracket 121, while the module sub-assembly tooling bracket 127 adopts a steel sheet metal structure.

[0074] As the name suggests, the aforementioned assembly tooling bracket 126 is used in conjunction with the corresponding instrument panel assembly tooling during the final assembly of the vehicle body to perform the assembly of the instrument panel reinforcement assembly and the instrument panel. The aforementioned module sub-assembly tooling bracket 127 is specifically used for the sub-assembly of the instrument panel module; that is, the module sub-assembly tooling bracket 127 can cooperate with the instrument panel module sub-assembly tooling to realize the sub-assembly of the instrument panel module.

[0075] By setting the final assembly tooling bracket 126 and the module assembly tooling bracket 127 on the body connecting brackets 121 at each end, it can be understood that, on the one hand, it facilitates the body assembly operation and helps improve the body assembly efficiency. On the other hand, making the final assembly tooling bracket 126 integrally molded on the body connecting bracket 121 can help reduce the design and manufacturing cost of the final assembly tooling bracket 126, while making the module assembly tooling bracket 127 adopt a steel sheet metal structure can ensure the rigidity and strength of the module assembly tooling bracket 127, which helps to ensure the reliability of the module assembly tooling bracket 127.

[0076] In practice, it is worth noting that the assembly tooling bracket 126, which is an integral structure with the body connecting bracket 121, can be formed on the body connecting bracket 121 during the preparation of the instrument panel reinforcing beam 1.

[0077] For the module assembly tooling bracket 127 with a steel sheet metal structure, it can be fixed to the vehicle body connecting bracket 121 by bolts, and to ensure the stability of the module assembly tooling bracket 127 fixed on the vehicle body connecting bracket 121, a metal bushing can be pre-embedded at the fixing point of the module assembly tooling bracket 127.

[0078] Depend on Figure 1 And continue to combine Figure 10 and Figure 11As shown, in some exemplary embodiments of this embodiment, the steering column mounting bracket 2 may be cast, for example, and structurally, the steering column mounting bracket 2 also has a frame portion 21 and a housing portion 22 connected to the inside of the frame portion 21.

[0079] The frame portion 21 has the connecting groove 2a formed on one side, while the housing portion 22 bulges downward relative to the frame portion 21, and steering column mounting points 2b are respectively provided on the frame portion 21 and the housing portion 22.

[0080] At this point, by casting the steering column mounting bracket 2, it can be understood that it not only facilitates the preparation of the steering column mounting bracket 2 and helps reduce the manufacturing cost of the steering column mounting bracket 2, but also ensures the structural strength of the steering column mounting bracket 2 and helps improve the stability of the steering column installation.

[0081] At the same time, the steering column mounting bracket 2 includes a frame portion 21 and a downwardly bulging shell portion 22. Obviously, this embodiment can utilize the high strength of the frame structure and the bulging structure to increase the rigidity of the steering column mounting bracket 2 itself, which is beneficial to improving the stability of the steering column installation.

[0082] In a specific implementation, the aforementioned frame portion 21 can be, for example, a square frame, and the cross-section of the downwardly bulging shell portion 22 can be, for example, similar to a "V" shape. The aforementioned steering column mounting point 2b can be, for example, an embedded mounting bolt. To facilitate the installation of the steering column mounting point 2b, an outwardly protruding portion 211 can be further formed on the side of the frame portion 21 with the connecting groove 2a. Part of the steering column mounting point 2b is located on this protruding portion 211, and the design of the protruding portion 211 obviously increases the structural strength at the location of the connecting groove 2a on the frame portion 21, thereby improving the connection stability between the steering column mounting bracket 2 and the reinforcing beam body 11.

[0083] In this embodiment, please refer to Figure 10 and Figure 11 As shown, in some exemplary embodiments, reinforcing ribs 23 may be provided on both the frame portion 21 and the housing portion 22, and some of the reinforcing ribs 23 on the frame portion 21 and the housing portion 22 may be connected together.

[0084] In this way, by providing reinforcing ribs 23 on the frame portion 21 and the shell portion 22 of the steering column mounting bracket 2, and connecting some of the reinforcing ribs 23 on the frame portion 21 and the shell portion 22 together, this embodiment can utilize the structural strengthening effect of the reinforcing ribs 23 to increase the structural strength of the frame portion 21 and the shell portion 22, and at the same time increase the connection strength between the frame portion 21 and the shell portion 22, which helps to further increase the rigidity of the steering column mounting bracket 2 and is conducive to better improving the stability of the steering column installation.

[0085] In specific implementation, the reinforcing ribs 23 located on the frame portion 21 and the shell portion 22 can be set based on the structural shape of the frame portion 21 and the shell portion 22. As an example, the reinforcing ribs 23 on the frame portion 21 can be located at its bottom, and reinforcing ribs 23 can be set on the upper and lower sides of the shell portion 22 respectively. The reinforcing ribs 23 located on the upper side of the shell portion 22 can be connected to the frame portion 21, and the reinforcing ribs 23 located on the lower side of the shell portion 22 can be connected to the reinforcing ribs 23 on the frame portion 21.

[0086] In this embodiment, please continue to refer to... Figure 10 and Figure 11 In some exemplary embodiments, weight-reducing holes 24 may be provided on both the frame portion 21 and the housing portion 22.

[0087] At this time, by providing weight reduction holes 24 on the frame portion 21 and the housing portion 22, it is understood that the weight of the steering column mounting bracket 2 can be reduced, which is beneficial to the lightweighting of the instrument panel reinforcement beam assembly and the vehicle body on which the instrument panel reinforcement beam assembly is installed.

[0088] In practice, there can be multiple weight-reducing holes 24 on both the frame part 21 and the shell part 22, and the shape of each weight-reducing hole 24 can be designed according to its location.

[0089] In addition, this embodiment is still as follows Figure 10 and Figure 11 As shown, the main body 11 of the reinforcing beam is connected to the connecting groove 2a on the steering column mounting bracket 2.

[0090] When connecting the steering column mounting bracket 2 and the reinforcing beam body 11, corresponding to each connecting hole 2c on the steering column mounting bracket 2, connecting through holes can be provided on the reinforcing beam body 11. Then, after the reinforcing beam body 11 is placed into the connecting groove 2a, the steering column mounting bracket 2 and the reinforcing beam body 11 are fixed together by the connectors that are inserted together in the connecting holes 2c and the connecting through holes.

[0091] Among them, the above-mentioned connecting parts can be bolts, and corresponding threaded mating structures (such as projection weld nuts or bushings pre-embedded in plastic brackets 12) can be set on the inner side of the reinforcing beam body 11 to achieve the fastening connection of the connecting parts.
