[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. In the absence of conflict, the following embodiments and features can be combined with each other.

[0047] In existing technologies, suspension beams, including longitudinal beams and transverse beams, can be manufactured by separate welding. Separate welding requires disassembling the suspension beam into multiple sheet metal parts, processing each part individually, aligning and splicing the parts together, and then welding them in place.

[0048] However, when aligning sheet metal parts, it is difficult to ensure accurate and stable positioning between the parts, resulting in low assembly precision of the welded suspension beam structure. This makes it difficult to accurately position and install with other beams, thus affecting the assembly and support of subsequent vehicle components.

[0049] This requires the use of specific welding fixtures to hold the sheet metal parts. However, the design and manufacture of these specific welding fixtures are complex and costly.

[0050] Therefore, the assembly of existing suspended beam structures made by separate welding is inconvenient.

[0051] To overcome the shortcomings of existing technologies, this application provides a suspension beam structure and vehicle. The suspension beam structure includes a mounting plate assembly and a side plate assembly. The mounting plate assembly and side plate assembly are processed separately and connected to form a support cavity to support vehicle components. A first positioning part is provided on the side plate assembly, and a first mating part adapted to the first positioning part is provided on the mounting plate assembly. Thus, when the mounting plate assembly and side plate assembly are assembled, they can be positioned by the insertion of the first positioning part and the first mating part, achieving precise and stable positioning of the assembly position. Precise and stable positioning can be achieved solely through insertion, making assembly convenient and reliable without the need for tooling. Therefore, after subsequent welding and fixing of the mounting plate assembly and side plate assembly, the overall assembly accuracy of the mounting plate assembly and side plate assembly is good. The good assembly accuracy of the overall assembly of the mounting plate assembly and side plate assembly further ensures the assembly accuracy between the suspension beam structures. Therefore, the suspension beam structure provided by this application solves the problem of inconvenient assembly of existing suspension beam structures.

[0052] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a suspended beam structure, including:

[0054] Mounting plate assembly 100, which is used to connect to the vehicle;

[0055] Side panel assembly 200, which is connected to mounting plate assembly 100 and together with mounting plate assembly 100 forms support cavity 201;

[0056] A first positioning part 230 is provided on the side panel assembly 200, and a first mating part 121 adapted to the first positioning part 230 is provided on the mounting plate assembly 100. The first positioning part 230 and the first mating part 121 are correspondingly positioned and inserted.

[0057] This application uses a crossbeam as an example to illustrate the suspended beam structure. The longitudinal beam is 400mm along... Figure 1 The beam extends along the X-direction, which is the length direction of the vehicle. Figure 1The Y-direction extension setting refers to the width direction of the vehicle.

[0058] It is understood that the mounting plate assembly 100 is used to connect to the vehicle, specifically to the longitudinal beam 400, so as to jointly support the vehicle components with the vehicle's longitudinal beam 400. By connecting the mounting plate assembly 100 to the longitudinal beam 400, the mounting plate assembly 100 can stably install subsequent structures such as the side plate assembly 200 on the vehicle, ensuring the stability and reliability of the entire structure.

[0059] After the side plate assembly 200 is connected to the mounting plate assembly 100, the two together form a support cavity 201. The structure of the support cavity 201 ensures both the rigidity and stability of the suspended beam structure support, while also preventing the suspended beam structure from becoming too heavy.

[0060] The first positioning part 230 and the first mating part 121 enable corresponding positioning and insertion between the mounting plate assembly 100 and the side plate assembly 200. This insertion method is simple and easy to operate, ensuring accurate alignment of the two components during installation, thus improving installation precision and efficiency. Simultaneously, the insertion connection provides a certain degree of connection strength, ensuring that the two components will not easily separate or undergo relative positional changes during use, facilitating stable and reliable subsequent welding processes, and guaranteeing that the final assembly precision of the supported suspension beam structure meets requirements.

[0061] After the side panel assembly 200 and the mounting plate assembly 100 are positioned and inserted, the side panel assembly 200, the mounting plate assembly 100, and other subsequent components need to be fastened by welding or other fastening methods.

[0062] Therefore, the suspension beam structure provided in this application embodiment includes a mounting plate assembly 100 and a side plate assembly 200. The mounting plate assembly 100 and the side plate assembly 200 are respectively processed and connected to form a support cavity 201 to support vehicle components. A first positioning part 230 is provided on the side plate assembly 200, and a first mating part 121 adapted to the first positioning part 230 is provided on the mounting plate assembly 100. Thus, when the mounting plate assembly 100 and the side plate assembly 200 are assembled, they can be positioned by the insertion of the first positioning part 230 and the first mating part 121, achieving precise and stable assembly positions. Furthermore, precise and stable positioning can be achieved solely through insertion, making assembly convenient and reliable without the need for tooling.

[0063] Therefore, after the mounting plate assembly 100 and the side plate assembly 200 are subsequently welded and fixed, the assembly accuracy of the overall components of the mounting plate assembly 100 and the side plate assembly 200 is good. Because of the good assembly accuracy of the overall components of the mounting plate assembly 100 and the side plate assembly 200, the assembly accuracy between the suspended beam structures is further guaranteed. Thus, the suspended beam structure provided by the embodiments of this application solves the problem of inconvenient assembly of existing suspended beam structures.

[0064] In some embodiments, refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the mounting plate assembly 100 includes a first mounting plate 110 and a second mounting plate 120, wherein the first mounting plate 110 is used to connect to a vehicle;

[0065] Side panel assembly 200 is disposed on first mounting plate 110;

[0066] The second mounting plate 120 is disposed on the side of the side plate assembly 200 away from the first mounting plate 110, so as to form a support cavity 201 together with the side plate assembly 200 and the first mounting plate 110.

[0067] A first mating part 121 is provided on at least one of the first mounting plate 110 and the second mounting plate 120.

[0068] The first mounting plate 110 is connected to the longitudinal beam 400 to ensure the reliability of the connection between the suspended beam structure and the longitudinal beam 400. The second mounting plate 120 is spaced apart from the first mounting plate 110, and a side plate assembly 200 is provided between them to form a support cavity 201, thereby improving the overall rigidity and strength of the suspended beam structure and better resisting external impacts and vibrations.

[0069] A first mating part 121 is provided on at least one of the first mounting plate 110 and the second mounting plate 120. A corresponding first positioning part 230 is provided on the side plate assembly 200.

[0070] In other embodiments, the first mating part 121 may be provided only on the first mounting plate 110, and the corresponding first positioning part 230 may be provided on the side plate assembly 200, with the second mounting plate 120 directly connected to the side plate assembly 200; or the first mating part 121 may be provided only on the second mounting plate 120, and the corresponding first positioning part 230 may be provided on the side plate assembly 200, with the first mounting plate 110 directly connected to the side plate assembly 200.

[0071] Furthermore, in some embodiments, reference is made to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the suspended beam structure also includes at least two reinforcing ribs 300;

[0072] A first mating part 121 is provided on one of the first mounting plate 110 and the second mounting plate 120;

[0073] The reinforcing rib 300 is connected to the other of the first mounting plate 110 and the second mounting plate 120, and the reinforcing rib 300 is connected to the side plate assembly 200.

[0074] At least two reinforcing ribs 300 are connected to the first mounting plate 110 and the second mounting plate 120, the one without the first mating part 121, and are also connected to the side plate assembly 200, which enhances the rigidity of the entire suspended beam structure and realizes the orderly connection of the first mounting plate 110, the second mounting plate 120 and the side plate assembly 200, so that the various components form a tight whole.

[0075] Furthermore, the stiffening rib 300 can provide further positioning reference for the installation process. By connecting the stiffening rib 300 only to the first mounting plate 110 or the second mounting plate 120, the splicing sequence and splicing position of each component of the crossbeam assembly can be effectively distinguished, ensuring the accurate installation position of each component. This helps to improve installation efficiency, reduce installation errors, and guarantee the quality and performance of the suspended beam structure.

[0076] For example, in this embodiment, a first mating part 121 is provided on the second mounting plate 120, and a first positioning part 230 is provided on the side of the side plate assembly 200 facing the second mounting plate 120. The side plate assembly 200 and the second mounting plate 120 are positioned and connected through the first mating part 121 and the first positioning part 230. The first mounting plate 110 and the side plate assembly 200 are connected by a reinforcing rib plate 300.

[0077] In other embodiments, a first mating part 121 may be provided on the first mounting plate 110, and the second mounting plate 120 and the side plate assembly 200 may be connected by a reinforcing rib plate 300. This application does not limit this.

[0078] Furthermore, a second positioning part 310 is provided on the reinforcing rib 300;

[0079] A second mating part 111 is provided on the other of the first mounting plate 110 and the second mounting plate 120, as well as on the side plate assembly 200;

[0080] The second positioning part 310 and the second mating part 111 are positioned and inserted in a one-to-one correspondence.

[0081] The second positioning part 310 and the second mating part 111 correspond one-to-one, providing clear positioning guidance for the installation of each component. During installation, the reinforcing rib plate 300 can be quickly and accurately aligned with the first mounting plate 110, the second mounting plate 120, and the side plate assembly 200 without the need for complex measurements and adjustments, thus shortening installation time and improving installation efficiency. This effectively reduces positional deviations during component installation, ensuring the overall accuracy of the suspended beam structure and preventing structural instability or functional abnormalities caused by installation errors.

[0082] Similarly, in specific implementation, since the second mounting plate 120 is provided with a first mating part 121 and the side plate assembly 200 is provided with a first positioning part 230 on the side facing the second mounting plate 120, it is only necessary to provide a second mating part 111 on the first mounting plate 110, a second mating part 111 on the side plate assembly 200, and a second positioning part 310 on the reinforcing rib 300.

[0083] It should be noted that in this embodiment, some of the reinforcing ribs 300 may be provided with the second positioning part 310, while the remaining reinforcing ribs 300 may not be provided with the second positioning part 310. The reinforcing ribs 300 provided with the second positioning part 310 may be located on the same side of the side plate assembly 200 to position the first mounting plate 110 from one side of the side plate assembly 200. The remaining reinforcing ribs 300 without the second positioning part 310 may be fixed in a preset position during the fastening step after the positioning and insertion of the suspended beam structure is completed; this application does not impose any restrictions on this.

[0084] In other embodiments, if the first mating part 121 is provided on the first mounting plate 110, then the second mating part 111 needs to be provided on the second mounting plate 120. This application does not impose any restrictions on this.

[0085] Furthermore, in some embodiments, reference is made to Figure 7 As shown, at least two second positioning parts 310 are provided on the reinforcing rib plate 300, and the at least two second positioning parts 310 are respectively located on different sides of the reinforcing rib plate 300.

[0086] At least two second positioning parts 310 located on different sides, after being connected to corresponding components, can constrain the reinforcing rib plate 300 and the components connected thereto from multiple directions, making the connection between the reinforcing rib plate 300 and the first mounting plate 110, the second mounting plate 120, and the side plate assembly 200 more stable. At the same time, since the planes of the side plate assembly 200 and the mounting plate assembly 100 are oriented in different directions, the placement of the second positioning parts 310 on different sides also makes the connection between the reinforcing rib plate 300 and each component more convenient and easier to operate.

[0087] For example, in this embodiment, the reinforcing rib plate 300 is generally triangular in shape, and a second positioning part 310 is provided on each of the two sides of the triangular plate to be positioned and inserted with the second mating part 111 on the first mounting plate 110 and the side plate assembly 200.

[0088] In some embodiments, refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, both the first positioning part 230 and the second positioning part 310 are protrusions, and both the first mating part 121 and the second mating part 111 are grooves or through holes.

[0089] Alternatively, both the first positioning part 230 and the second positioning part 310 may be grooves or through holes, and both the first mating part 121 and the second mating part 111 may be protrusions.

[0090] Understandably, the way the tabs mate with the grooves or through holes provides intuitive positioning. During installation, the tabs can be easily aligned with the grooves or through holes, achieving rapid positioning without the need for complex measurement and adjustment processes, significantly improving installation efficiency.

[0091] Meanwhile, after the tab is inserted into the groove or through hole, a mechanical locking structure is formed, which can restrict the relative movement between the two positioning components in multiple directions perpendicular to the insertion direction, effectively resisting the action of external forces such as tension, shear force and torque, thus ensuring the stability of the positioning connection between the first mounting plate 110, the second mounting plate 120 and the side plate assembly 200.

[0092] It should be noted that, in order to facilitate the differentiation of the first mating part 121 and the second mating part 111, as well as the differentiation of the corresponding first positioning part 230 and the second positioning part 310, the structure or size of the first positioning part 230 and the second positioning part 310 may be different. For example, one of the first positioning part 230 and the second positioning part 310 may have a conventional angular structure on its edge, while the other may have a rounded corner structure on its edge. Alternatively, a mark may be painted on one of the first positioning part 230 and the second positioning part 310, and a corresponding mark may be painted on the first mating part 121 and the second mating part 111 for differentiation. This application does not impose any restrictions on this.

[0093] In practice, at least one of the mounting plate assembly 100, the side plate assembly 200, and the reinforcing rib plate 300 is a laser-cut component.

[0094] Understandably, laser cutting, as a non-contact processing method, uses a high-energy-density laser beam to melt and vaporize materials, thereby achieving cutting. Its focused spot is extremely small, allowing for precise control of the cutting path and keeping cutting accuracy within a very small range. Compared to traditional cutting methods such as mechanical cutting and flame cutting, it effectively avoids dimensional deviations caused by tool wear and mechanical vibration during the cutting process, ensuring that the dimensions of each component strictly meet design requirements. Therefore, using laser cutting for at least one of the mounting plate assembly 100, side plate assembly 200, and reinforcing rib plate 300 effectively guarantees the accuracy of key dimensions of its positioning parts, mating parts, and other holes, thereby ensuring the precision of the suspended beam structure assembly and the accuracy of its connection with the longitudinal beam 400.

[0095] Furthermore, in some embodiments, reference is made to Figure 3 and Figure 6 As shown, the side panel assembly 200 includes a first side panel 210 and a second side panel 220, and the first side panel 210 and the second side panel 220 are each provided with at least two first positioning parts 230 at intervals along their own extension direction.

[0096] Along the extending direction of the first side plate 210 and the second side plate 220, the size of the first positioning part 230 on one of the first side plate 210 and the second side plate 220 is larger than the size of the first positioning part 230 on the other.

[0097] The multiple spaced first positioning parts 230 provide multiple positioning points for the installation of the side panel assembly 200, so as to ensure that the first side panel 210 and the second side panel 220 are accurately aligned with the mounting plate assembly 100 during the installation process, thereby improving the assembly accuracy between the side panel assembly 200 and the mounting plate assembly 100.

[0098] Meanwhile, the first positioning parts 230 of different sizes on the first side plate 210 and the second side plate 220 provide clear distinguishing marks for the installation process. This allows for quick determination of the correct installation position and orientation of the first side plate 210 and the second side plate 220 based on the size differences, avoiding structural instability or functional abnormalities caused by incorrect installation.

[0099] For example, in this embodiment, three first positioning portions 230 are provided at intervals on one side of both the first side plate 210 and the second side plate 220. The length of the first positioning portion 230 on the first side plate 210 is smaller than the length of the first positioning portion 230 on the second side plate 220. Correspondingly, two rows of first mating portions 121 are provided on the second mounting plate 120, with three first mating portions 121 in each row. The length of the first mating portion 121 corresponding to the first side plate 210 is smaller than the length of the first mating portion 121 corresponding to the second side plate 220. At the same time, a second mating portion 111 is also provided on at least one of the first side plate 210 and the second side plate 220 to be positioned and inserted into the second positioning portion 310 on the reinforcing rib plate 300.

[0100] In other embodiments, other numbers of first positioning portions 230 may be provided, and the number of first positioning portions 230 or first mating portions 121 on the first side plate 210 and the second side plate 220 may be different, so as to distinguish the first side plate 210 and the second side plate 220.

[0101] Furthermore, in some embodiments, reference is made to Figure 4 As shown, one end of the mounting plate assembly 100 is provided with a first connection hole 112, and the other end is provided with a second connection hole 113. Both the first connection hole 112 and the second connection hole 113 are used for connection with the vehicle.

[0102] One of the first connecting hole 112 and the second connecting hole 113 is a strip-shaped hole provided along the extending direction of the mounting plate assembly 100.

[0103] Since the first mounting plate 110 is used to connect with the longitudinal beam 400, both the first connecting hole 112 and the second connecting hole 113 are provided on the first mounting plate 110, and the second connecting hole 113 is set as a strip hole. A fastening nut 130 can be provided on both the first connecting hole 112 and the second connecting hole 113, so that the fastener is securely connected to the hole on the longitudinal beam 400 through the fastening nut 130 and the corresponding connecting hole.

[0104] The slotted holes provide a certain adjustment space for installation. Through the slotted holes, the suspension beam structure can accommodate a certain degree of dimensional error of the longitudinal beam 400 in its extension direction, allowing for fine-tuning. This enables the mounting plate assembly 100 to be smoothly connected to the longitudinal beam 400, reducing installation difficulty and improving installation efficiency.

[0105] Therefore, when installing other vehicle components on the suspension beam structure and longitudinal beam 400, this slot can also be used to ensure the compatibility of the suspension beam structure and longitudinal beam 400 with components that have a certain size difference.

[0106] Furthermore, weight-reducing holes 240 are provided on the first mounting plate 110, the second mounting plate 120, the first side plate 210 and the second side plate 220. Specifically, they can be rectangular weight-reducing holes 240 or circular weight-reducing holes 240. In this way, the weight of the entire suspension beam structure is reduced while ensuring the strength of the suspension beam structure, thus achieving lightweighting.

[0107] The assembly of the suspended beam structure will be described below using one embodiment of the present application:

[0108] Step 1: Weld each fastening nut 130 to the corresponding hole positions on the first mounting plate 110, the second mounting plate 120, the first side plate 210, and the second side plate 220;

[0109] Step 2: The first positioning part 230 on the first side plate 210 and the second side plate 220 are respectively snapped into the first mating part 121 of the second mounting plate 120, and intermittent welding is performed on the first side plate 210 and the second mounting plate 120, and on the second side plate 220 and the second mounting plate 120 along the extending direction of the second mounting plate 120.

[0110] Step 3: Position the second positioning part 310 of each reinforcing rib plate 300 into the second mating part 111 on the first side plate 210 and the second side plate 220, and perform full welding fixation between the reinforcing rib plate 300 and the first side plate 210, and between the reinforcing rib plate 300 and the second side plate 220.

[0111] Step 4: The assembly with the fastening nut 130, the second mounting plate 120, the first side plate 210, the second side plate 220 and the reinforcing rib plate 300 welded together is positioned onto the second mating part 111 of the first mounting plate 110 using the remaining second positioning part 310 on the reinforcing rib plate 300, and intermittent welding is performed between the reinforcing rib plate 300 and the first mounting plate 110.

[0112] Step 5: Weld the remaining components to their corresponding positions. For example, provide a reinforcing rib plate 300 without the second positioning part 310, and weld it directly between the side plate assembly 200 and the first mounting plate 110 in this step.

[0113] This application also provides a vehicle, including a vehicle body and any of the above-described suspension beam structures disposed on the vehicle body.

[0114] The suspended beam structure has been described in the above embodiments and will not be repeated here.

[0115] The vehicle provided in this application embodiment features a suspension beam structure, including a mounting plate assembly 100 and a side plate assembly 200. The mounting plate assembly 100 and the side plate assembly 200 are respectively machined and interconnected to form a support cavity 201 to support vehicle components. A first positioning part 230 is provided on the side plate assembly 200, and a first mating part 121 adapted to the first positioning part 230 is provided on the mounting plate assembly 100. Thus, when the mounting plate assembly 100 and the side plate assembly 200 are assembled, they can be positioned by the insertion of the first positioning part 230 and the first mating part 121, achieving precise and stable assembly. Furthermore, precise and stable positioning can be achieved solely through an insertion operation, making assembly convenient and reliable without the need for tooling.

[0116] Therefore, after the mounting plate assembly 100 and the side plate assembly 200 are subsequently welded and fixed, the assembly accuracy of the overall components of the mounting plate assembly 100 and the side plate assembly 200 is good. Because of the good assembly accuracy of the overall components of the mounting plate assembly 100 and the side plate assembly 200, the assembly accuracy between the suspended beam structures is further guaranteed. Thus, the suspended beam structure provided by the embodiments of this application solves the problem of inconvenient assembly of existing suspended beam structures.

[0117] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0118] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0119] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0120] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
