Technical Field
[0001] This utility model relates to the field of vehicle parts technology, specifically to an integrated cast tube beam and steering gear mounting structure. Background Technology
[0002] Traditional instrument panel beams, steering gear mounting brackets, and supports for other vehicle body components are all made of welded steel structures. These welded steel structures consist of a main beam arranged laterally (extending from the driver's side to the subframe), forming the skeleton supporting the entire dashboard. Multiple brackets, mostly cantilever brackets, are welded or screwed onto this skeleton to mount other components. The instrument panel beams and steering gear mounting brackets are connected by welding, involving numerous components and a complex manufacturing process. Ensuring welding quality is difficult, easily leading to premature failure of the connection between the instrument panel beams and steering gear mounting brackets, which is detrimental to the overall structural stability. Furthermore, the overall weight of the steel structure is significant, hindering lightweight vehicle design. Therefore, a high-strength, lightweight instrument panel beam and steering gear mounting bracket structure is needed. Utility Model Content

[0016] Furthermore, a third weight-reducing groove is formed on the second mounting part, and a second reinforcing horizontal rib and a second reinforcing vertical rib are formed in the third weight-reducing groove; the second reinforcing horizontal rib is arranged along the length direction of the mounting beam; the second reinforcing vertical rib is perpendicular to the second reinforcing horizontal rib.
[0017] According to the above-mentioned technical means, the third weight-reducing groove reduces the weight of the second mounting part, while the second reinforcing horizontal rib and the second reinforcing vertical rib are used to strengthen the structural strength of the second mounting part, so as to make the second mounting part lightweight while ensuring the strength of the second mounting part.
[0018] Furthermore, a connecting hole is formed on the side wall of the third weight-reducing groove away from the mounting beam, and the connecting hole is used to connect the second mounting part to the vehicle body by connecting bolts.
[0019] Based on the above technical means, the connecting hole provides positioning for the second mounting part to connect to the vehicle body, and the connection method of connecting bolts and connecting holes is simple and reliable.
[0020] Furthermore, weight-reducing holes are formed on the sidewalls of the second reinforcing rib and / or the third weight-reducing groove, and the weight-reducing holes are used to reduce the weight of the second mounting part.
[0021] Based on the above-mentioned technical means, the weight reduction hole can further reduce the weight of the second mounting part, making the second mounting part lightweight.
[0022] Furthermore, a second connecting portion is formed on the second mounting portion, the second connecting portion being used to connect the vehicle steering gear.

[0028] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.
[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0030] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.
[0031] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0032] This embodiment provides, as follows: Figures 1 to 6 The diagram shows an integrated cast tube beam and steering gear mounting structure, comprising: a mounting beam 100 and a steering gear mounting bracket 200, wherein the middle of the mounting beam 100 is bent into a U-shape; both ends of the mounting beam 100 can be mounted on the vehicle body to support the vehicle's dashboard; the steering gear mounting bracket 200 includes a first mounting portion 210 and a second mounting portion 220, both of which are mounted on the mounting beam 100; the first mounting portion 210 is used to connect the vehicle steering gear; the second mounting portion 220 is used to connect the vehicle steering gear and the vehicle body; the mounting beam 100, the first mounting portion 210, and the second mounting portion 220 are integrally cast.
[0033] To achieve a lightweight overall structure, the integrally cast structure of the mounting beam 100, the first mounting part 210, and the second mounting part 220 is made of aluminum alloy or other high-strength lightweight metals. This ensures the overall structural strength while reducing the structural weight, which is beneficial to the development of vehicle lightweighting.
[0034] The integral casting of the crossbeam 100, the first mounting part 210, and the second mounting part 220 can reduce the number of production molds, thereby simplifying the production process and reducing production costs; it can also achieve the effects of good rigidity, simple manufacturing, and high integration.
[0035] The U-shaped mounting beam 100 in the middle can adapt to the vehicle body structure. The mounting beam 100 and the first mounting part 210 and the second mounting part 220 of the steering gear mounting bracket 200 are integrally cast, avoiding the weak connection problem caused by traditional welding or screwing. This effectively improves the connection strength and stability between the steering gear mounting bracket 200 and the mounting beam 100, and extends the service life. The integral casting production method also simplifies the assembly steps and manufacturing process of the steering gear mounting bracket 200 and the mounting beam 100, and reduces the complexity of production.
[0036] like Figure 2 and Figure 3 As shown, in this embodiment, a first weight-reducing groove 110, a plurality of first reinforcing ribs 120, and a plurality of second reinforcing ribs 130 are formed on the mounting beam 100. The first weight-reducing groove 110 is arranged along the length direction of the mounting beam 100. Each first reinforcing rib 120 and each second reinforcing rib 130 is formed within the first weight-reducing groove 110 and is spaced apart along the length direction of the first weight-reducing groove 110. Adjacent first reinforcing ribs 120 and second reinforcing ribs 130 form a "V" shape or a "V" shape. The first weight-reducing groove 110 reduces the weight of the mounting beam 100, while the first reinforcing ribs 120 and second reinforcing ribs 130 strengthen the structural strength of the mounting beam 100, thus ensuring the strength of the mounting beam 100 in use and making it lightweight. The "V" shape or "V" shape formed by the first reinforcing ribs 120 and second reinforcing ribs 130 can provide multi-directional structural reinforcement to the mounting beam 100, ensuring the load-bearing strength of the mounting beam 100. To achieve excellent multi-directional reinforcement, multiple first reinforcing ribs 120 are arranged in parallel with each other, and multiple second reinforcing ribs 130 are arranged in parallel with each other, with each first reinforcing rib 120 and each second reinforcing rib 130 forming an angle of approximately 45°, of which 45°±5° is preferred.
[0037] like Figure 3As shown, in this embodiment, third reinforcing ribs 140 are formed at both ends of the mounting beam 100. These third reinforcing ribs 140 are located within the first weight-reducing groove 110 and are used to reinforce the ends of the mounting beam 100. Specifically, two parallel third reinforcing ribs 140 are formed at each end of the mounting beam 100, and each third reinforcing rib 140 is perpendicular to the beam body of the mounting beam 100. Since both ends of the mounting beam 100 can be mounted on the vehicle body, the third reinforcing ribs 140 can reinforce the ends of the mounting beam 100, preventing deformation or damage due to excessive force when the ends of the mounting beam 100 are mounted on the vehicle body.
[0038] like Figure 3 As shown, in this embodiment, both ends of the mounting beam 100 are provided with a first connecting plate 150 and a second connecting plate 160. Each first connecting plate 150 and each second connecting plate 160 is located on both sides of the mounting beam 100, used to mount the mounting beam 100 onto the vehicle body. When mounting the mounting beam 100 onto the vehicle body, it is secured to the vehicle body by passing multiple bolts through the first connecting plate 150 and the second connecting plate 160 (corresponding to the bolts, through holes are formed on the first connecting plate 150 and the second connecting plate 160 for the bolts to pass through). The first connecting plate 150 and the second connecting plate 160 provide a mounting base for the ends of the mounting beam 100 mounted on the vehicle body, and provide mounting supports on both sides of the mounting beam 100, forming lateral limiting, which effectively ensures the strength of the mounting beam 100 mounted on the vehicle body and prevents the mounting beam 100 from loosening.
[0039] like Figure 2 and Figure 5 As shown, in this embodiment, a second weight-reducing groove 211 is formed on the first mounting portion 210, and a first reinforcing horizontal rib 212 and a first reinforcing vertical rib 213 are formed inside the second weight-reducing groove 211; the first reinforcing horizontal rib 212 is arranged along the length direction of the mounting beam 100; the first reinforcing vertical rib 213 is perpendicular to the first reinforcing horizontal rib 212; specifically, the two opposite sides of the first reinforcing horizontal rib 212 are respectively connected to the two opposite inner sidewalls of the second weight-reducing groove 211; the first reinforcing vertical rib 213 and the first reinforcing horizontal rib 212 form a cross structure and are perpendicular to the first reinforcing horizontal rib 212, as specifically arranged as follows. Figure 5 As shown. The second weight-reducing groove 211 reduces the weight of the first mounting part 210, while the first reinforcing horizontal rib 212 and the first reinforcing vertical rib 213 strengthen the structural strength of the first mounting part 210, thus ensuring the strength of the first mounting part 210 while making it lightweight. Of course, multiple first reinforcing horizontal ribs 212 and / or multiple first reinforcing vertical ribs 213 can also be formed in the second weight-reducing groove 211 to better strengthen the first mounting part 210.
[0040] like Figure 5As shown, in this embodiment, a first connecting portion 2111 is formed on the side wall of the second weight-reducing groove 211 away from the mounting beam 100. The first connecting portion 2111 is used to connect the vehicle steering gear. When connecting the first connecting portion 2111 to the vehicle steering gear, the two are connected by bolts passing through the first connecting portion 2111. Correspondingly, a through hole for the bolt to pass through is formed on the first connecting portion 2111. The first connecting portion 2111 provides a connection position for the vehicle steering gear to be connected to the first mounting portion 210, which facilitates quick and accurate connection of the vehicle steering gear to the first mounting portion 210 during assembly.
[0041] like Figure 2 and Figure 5 As shown, in this embodiment, a third weight-reducing groove 221 is formed on the second mounting portion 220, and a second reinforcing horizontal rib 222 and a second reinforcing vertical rib 223 are formed within the third weight-reducing groove 221. The second reinforcing horizontal rib 222 is arranged along the length direction of the mounting beam 100; the second reinforcing vertical rib 223 is perpendicular to the second reinforcing horizontal rib 222. Specifically, the opposite two sides of the second reinforcing horizontal rib 222 are connected to the opposite two inner sidewalls of the third weight-reducing groove 221; one side of the second reinforcing vertical rib 223 is connected to the mounting beam 100, and the opposite other side is connected to the second reinforcing horizontal rib 222. The third weight-reducing groove 221 reduces the weight of the second mounting portion 220, while the second reinforcing horizontal rib 222 and the second reinforcing vertical rib 223 are used to strengthen the structural strength of the second mounting portion 220, thus ensuring the strength of the second mounting portion 220 while making it lightweight. Of course, in order to better strengthen the second mounting part 220, multiple second reinforcing horizontal ribs 222 and / or multiple second reinforcing vertical ribs 223 may be formed in the third weight reduction groove 221.
[0042] like Figure 5 As shown, in this embodiment, a connecting hole 2211 is formed on the side wall of the third weight-reducing groove 221 away from the mounting beam 100. The connecting hole 2211 is used to connect the second mounting part 220 to the vehicle body through connecting bolts. The connecting hole 2211 provides positioning for the second mounting part 220 to connect to the vehicle body, and the connection method of connecting bolts cooperating with connecting hole 2211 is simple and reliable.
[0043] like Figure 5 and Figure 6 As shown, in this embodiment, weight-reducing holes 2231 are formed on the sidewalls of the second reinforcing vertical rib 223 and / or the third weight-reducing groove 221. These holes are used to reduce the weight of the second mounting portion 220. The weight-reducing holes 2231 further reduce the weight of the second mounting portion 220, making it lighter. The triangular-shaped holes 2231 ensure the structural strength and stability of the sidewalls of the second reinforcing vertical rib 223 and / or the third weight-reducing groove 221.
[0044] like Figure 5 and Figure 6 As shown, in this embodiment, a second connecting portion 224 is formed on the second mounting portion 220, which is used to connect the vehicle steering gear. The second connecting portion 224 provides a connection base for the second mounting portion 220 to connect to the vehicle steering gear, and can also work together with the first connecting portion 2111 on the first mounting portion 210 to form a two-point connection between the steering gear mounting bracket 200 and the vehicle steering gear, ensuring the stability of the connection between the steering gear mounting bracket 200 and the vehicle steering gear. The mounting portion where the first mounting portion 210, the second mounting portion 220, and the connecting hole 2211 are located together provide mounting for the vehicle steering gear to connect to the vehicle body, ensuring the connection strength of the entire mounting structure.
[0045] like Figure 6 As shown, the second connecting portion 224 extends outward from the second mounting portion 220 and forms a "П"-shaped structure in cross-section. All three sides of the "П"-shaped structure can connect to the vehicle steering gear to ensure the strength and stability of the connection between the second connecting portion 224 and the vehicle steering gear. The groove formed by the "П"-shaped structure communicates with the third weight-reducing groove 221, creating a cavity at the connection between the "П"-shaped structure and the third weight-reducing groove 221, thereby reducing the weight of the second mounting portion 220.
