[0029] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0030] In this application, the terms "comprising," "including," "having," 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.

[0031] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0032] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0033] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0034] In the design of the helical spring combination bracket, in order to reduce structural complexity, decrease the number of parts, and facilitate management, such as... Figures 1-3 As shown, the present invention provides a helical spring combination bracket. The helical spring combination bracket includes a combination bracket body 1 and a central reinforcing member 2.

[0035] The combined bracket body 1 is L-shaped and includes an interconnected mounting side 11 and a spring mounting part 12. The mounting side 11 has multiple first connecting holes 111 and multiple second connecting holes 112 spaced apart. Multiple first fasteners 210 pass through the first connecting holes 111 and the second connecting holes 112 and connect to the longitudinal beam 100 of the vehicle frame. The spring mounting part 12 has multiple third connecting holes 121, and second fasteners pass through the second connecting holes 112 and connect to the helical buffer spring mounting seat 6. A central reinforcing member 2 is disposed on the combined bracket body 1 and connects to both the mounting side 11 and the spring mounting part 12. The central reinforcing member 2 has a fourth connecting hole 21, and third fasteners pass through the fourth connecting hole 21 and connect to the suspension buffer block 9.

[0036] In this way, the central reinforcing member 2 of the main body used to install the suspension buffer block 9 is integrated into the combined bracket body 1. This facilitates the installation of the helical buffer spring mounting seat 6 and the suspension buffer block 9, while reducing structural complexity, decreasing the number of parts, and simplifying management.

[0037] In some embodiments, the helical spring assembly bracket further includes a first reinforcing rib 3, which is disposed at one end of the assembly bracket body 1 and is connected to both the mounting side 11 and the spring mounting part 12. By providing the first reinforcing rib 3, the mounting side 11 and the spring mounting part 12 can be supported, thereby improving the strength of the assembly bracket body 1 and preventing deformation of the assembly bracket body 1 during subsequent use.

[0038] In some embodiments, the helical spring assembly bracket further includes a second reinforcing rib 5, which is disposed at the end of the assembly bracket body 1 away from the first reinforcing rib 3, and is connected to both the mounting side 11 and the spring mounting part 12. By providing the second reinforcing rib 5, the mounting side 11 and the spring mounting part 12 can be supported. The first reinforcing rib 3 and the second reinforcing rib 5 work together to further enhance the strength of the assembly bracket body 1, preventing deformation of the assembly bracket body 1 during subsequent use.

[0039] In some embodiments, the spring mounting portion 12 has multiple soft pad bracket holes 122, located between the first reinforcing rib 3 and the central reinforcing member 2 of the main body. The soft pad bracket holes 122 provide pre-drilled holes for installing the front suspension auxiliary soft pad bracket 8. For lightweight vehicle bodies, the soft pad bracket holes 122 are not used for any connection; for heavy-duty vehicle bodies, the soft pad bracket holes 122 are connected to the front suspension auxiliary soft pad bracket 8 of the vehicle body. Through this configuration, for lightweight vehicle bodies, the soft pad bracket holes 122 reduce weight, lowering the weight of the coil spring assembly bracket and achieving a lightweight design; for heavy-duty vehicle bodies, they facilitate the installation of the front suspension auxiliary soft pad bracket 8, improving the integration of the coil spring assembly bracket.

[0040] In some embodiments, the helical spring assembly bracket further includes a cylindrical reinforcing member 4, which is fixedly mounted on the spring mounting portion 12 and connected to the central reinforcing member 2 of the main body. By providing the cylindrical reinforcing member, the strength of the assembly bracket body 1 can be further improved. Moreover, the cylindrical reinforcing member 4 has comprehensive bending and torsional resistance, which can further improve the mechanical properties of the assembly bracket body 1 and prevent deformation.

[0041] In some embodiments, a plurality of hinge pad holes 41 are provided at intervals on the end face of the cylindrical reinforcing member 4. By providing hinge pad holes 41 on the cylindrical reinforcing member 4, the hinge pad holes 41 are threaded blind holes, which are connected to the front suspended hinge pad bracket 7 by screws, making it convenient to install the hinge pad.

[0042] In some embodiments, a plurality of weight-reducing holes 113 are spaced apart on the mounting side 11, and the weight-reducing holes 113 are elongated. By providing weight-reducing holes 113, the weight of the combined bracket body 1 can be further reduced, saving materials and achieving a lightweight design. Moreover, designing the weight-reducing holes 113 as elongated facilitates processing.

[0043] In some embodiments, a gas spring mounting hole 123 is provided at the third connecting hole 121, and a gas spring mounting seat can be installed at this location as needed.

[0044] In some embodiments, the helical spring assembly bracket is made of isothermally hardened ductile iron, specifically material grade QTD900-8. Using the above-mentioned material to manufacture the helical spring assembly bracket ensures its strength.

[0045] like Figure 4 As shown, this embodiment also provides a combined bracket assembly, which includes a large bracket 200 and the aforementioned coil spring combined bracket. The large bracket 200 and the coil spring combined bracket are located on both sides of the frame longitudinal beam 100. A first fastener 210 passes through the first connecting hole 111 and is connected to the large bracket 200. In this embodiment, the first fastener 210 is a bolt, which passes through the first connecting hole 111, the frame longitudinal beam 100, and the large bracket 200 before being connected to a nut. Through this method, only one set of first fasteners 210 is needed to complete the installation of the large bracket 200 and the coil spring combined bracket on the frame longitudinal beam 100, reducing installation difficulty and saving on fastener usage.

[0046] In some embodiments, the combined bracket assembly further includes a suspension connecting bracket 300, which is disposed on the side of the frame longitudinal beam 100 opposite to the combined bracket body 1. A first fastener 210 passes through a second connecting hole 112 and connects to the suspension connecting bracket 300. In this embodiment, the second connector is a bolt, which passes through the second connecting hole 112, the frame longitudinal beam 100, and the suspension connecting bracket 300 before being connected to a nut. Through this method, only one set of second fasteners is needed to complete the installation of the suspension connecting bracket 300 and the coil spring combined bracket on the frame longitudinal beam 100, reducing installation difficulty and saving on fastener usage.

[0047] This embodiment also provides a vehicle, which includes a vehicle body and the above-described combined support assembly. The combined support assembly is mounted on the vehicle body, reducing structural complexity, decreasing the number of parts, and facilitating management.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
