Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a front extension beam of a chassis, a chassis assembly, and a vehicle. Background Technology

[0002] The cab front suspension, bumper, front underrun protection, steering gear and radiator of a vehicle usually need to be mounted on the frame. In traditional solutions, each component needs to be equipped with a different bracket, which takes up a lot of space and is structurally complex.

[0003] To address this, existing technology provides a front extended beam integrated bracket that integrates the mounting parts of structures such as the front suspension leaf spring, steering gear, radiator, front lower guard, front tow hook, cab front suspension bracket, and front crossbeam to form a front extended beam integrated bracket, thereby simplifying the structure and reducing space occupation. However, a problem arises because, after integrating so many structures, the main body of the integrated bracket needs to be made thicker to ensure the required structural strength, thus increasing the weight and cost of the integrated bracket. Summary of the Invention

[0004] According to one aspect of the present invention, the present invention provides a front extension beam for the vehicle frame to solve the problem that in the prior art, after integrating a number of mounting parts, the main body of the integrated bracket needs to be made thicker, which leads to an increase in the weight and cost of the integrated bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The front extension beam of the vehicle frame includes an extension beam body, the extension beam body including a first side plate and a second side plate spaced apart, and a top plate and a bottom plate located between the first side plate and the second side plate. The top plate and the bottom plate are spaced apart. The first side plate includes a first extension section and a second extension section connected to each other. Along the longitudinal direction of the vehicle body, the first extension section is located in front of the second extension section. The first extension section, the top plate, the second side plate and the bottom plate are sequentially connected to form an integrated bracket. The integrated bracket is used to connect with at least one of the cab front suspension, bumper, front underrun protection, steering gear and radiator. The second extension section is used to connect to the longitudinal beam of the vehicle frame assembly.

[0007] As a preferred embodiment of the front extension beam of the chassis, the top plate extends rearward and connects to the second extension section; the bottom plate extends rearward and connects to the second extension section.

[0008] As a preferred embodiment of the front extension beam of the vehicle frame, the main body of the extension beam also includes a reinforcing plate that is connected to both the top plate and the bottom plate. The reinforcing plate is spaced apart from the second extension section and is located behind the second side plate along the front-rear direction of the vehicle body.

[0009] As a preferred embodiment of the extended front beam of the chassis, it also includes a first steering gear mounting part and a second steering gear mounting part, which are used to mount the steering gear. The first steering gear mounting part is disposed on the second side plate, and the second steering gear mounting part is disposed on the reinforcing plate.

[0010] As a preferred embodiment of the front extension beam of the chassis, it also includes an extension plate disposed at the front end of the integrated bracket, and a front lower protection mounting part is provided on the rear side of the extension plate, the front lower protection mounting part being used to install the front lower protection.

[0011] As a preferred embodiment of the front extension beam of the vehicle frame, the front side of the extension plate is provided with a bumper mounting part, which is used to install the bumper.

[0012] According to another aspect of the invention, a frame assembly is provided, including the aforementioned front extension beam, and further including two longitudinal beams and a plurality of crossbeams that simultaneously connect the two longitudinal beams and are located between the two longitudinal beams, wherein the second extension connects the longitudinal beams.

[0013] As a preferred embodiment of the frame assembly, there are two front extension beams, which are connected to the two longitudinal beams in a one-to-one correspondence, and the first side plates of the two front extension beams are located between the second side plates of the two front extension beams.

[0014] As a preferred embodiment of the frame assembly, along the rear-to-front direction, the first side plate of any of the front extension beams of the frame extends in a direction away from the other front extension beam.

[0015] According to another aspect of the invention, a vehicle is provided, including the aforementioned frame assembly, and further including a cab front suspension, a bumper, a front underrun protection, a steering gear, and a radiator, the integrated bracket being for connection to at least one of the cab front suspension, the bumper, the front underrun protection, the steering gear, and the radiator.

[0016] The beneficial effects of this invention are:

[0017] This invention provides a front extension beam for a vehicle frame, including an extension beam body. The extension beam body includes a first side plate and a second side plate spaced apart, and a top plate and a bottom plate located between the first and second side plates. The top plate and the bottom plate are spaced apart. The first side plate includes a first extension section and a second extension section connected to each other. Along the longitudinal direction of the vehicle body, the first extension section is located in front of the second extension section. The first extension section, the top plate, the second side plate, and the bottom plate are sequentially connected to form an integrated bracket. The integrated bracket is used to connect with at least one of the following: the front suspension of the cab, the bumper, the front underrun protection, the steering gear, and the radiator. By sequentially connecting the first extension section, the top plate, the second side plate, and the bottom plate, the structural strength of the integrated bracket can be increased, and the vehicle's components can be configured in any one or any two of the first extension section, the second side plate, the top plate, and the bottom plate according to actual needs. Furthermore, because the first and second side plates are spaced apart, and the top plate and the bottom plate are spaced apart, the integrated bracket has an internal cavity, which can reduce weight. The second extension is used to connect the longitudinal beams of the frame assembly, thereby connecting the vehicle's structural components to the longitudinal beams of the frame assembly. Furthermore, connecting the longitudinal beams of the frame assembly solely through the second extension can further simplify the structure while meeting structural strength requirements.

[0018] The present invention also provides a frame assembly, including the aforementioned front extended beam, two longitudinal beams, and a plurality of crossbeams connecting the two longitudinal beams and located between them, with a second extension connecting the longitudinal beams. In this front extended beam, by sequentially connecting the first extension, top plate, second side plate, and bottom plate, the structural strength of the integrated bracket can be increased, and the vehicle's components can be arranged in any one or any two of the first extension, second side plate, top plate, and bottom plate according to actual needs. Furthermore, since the first side plate and second side plate are spaced apart, and the top plate and bottom plate are spaced apart, the integrated bracket has an internal cavity, which can reduce weight. The second extension connects the longitudinal beams of the frame assembly, thereby connecting the vehicle's components to the longitudinal beams of the frame assembly. Moreover, connecting the longitudinal beams of the frame assembly only through the second extension further simplifies the structure while meeting structural strength requirements.

[0019] The present invention also provides a vehicle including the aforementioned frame assembly, further comprising a cab front mount, bumper, front underrun protection, steering gear, and radiator, with an integrated bracket for connection to at least one of the cab front mount, bumper, front underrun protection, steering gear, and radiator. This frame assembly can be connected to at least one of the cab front mount, bumper, front underrun protection, steering gear, and radiator via a front frame extension beam, saving space, simplifying the structure, and ensuring that the structural strength of the front frame extension beam meets requirements.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] The front suspension, bumper, front underrun protection, steering gear, and radiator of a vehicle typically need to be mounted on the chassis. Traditionally, each component requires a separate bracket, resulting in significant space consumption and structural complexity. To address this, existing technology offers a front extended beam integrated bracket that integrates the mounting points for the front suspension leaf springs, steering gear, radiator, front underrun protection, front tow hook, front suspension bracket, and front crossbeam, simplifying the structure and reducing space requirements. However, a drawback is that integrating so many structures necessitates a thicker main body of the integrated bracket to ensure sufficient structural strength, increasing its weight and cost.

[0037] To address the aforementioned issues, this embodiment provides a front extension beam for the vehicle frame. This solves the problem in the prior art where, after integrating a number of mounting components, the main body of the integrated bracket needs to be made thicker, which leads to an increase in the weight and cost of the integrated bracket. This invention can be applied to the field of vehicle technology, specifically to commercial vehicles, as well as other types of vehicles such as passenger cars.

[0038] Reference Figures 1-5 The front extension beam of the vehicle frame includes an extension beam body 1. The extension beam body 1 includes a first side plate 11 and a second side plate 12 spaced apart, and a top plate 13 and a bottom plate 14 located between the first side plate 11 and the second side plate 12. The top plate 13 and the bottom plate 14 are spaced apart. The first side plate 11 includes a first extension section 111 and a second extension section 112 connected to each other. Along the front-rear direction of the vehicle body, the first extension section 111 is located in front of the second extension section 112. The first extension section 111, the top plate 13, the second side plate 12 and the bottom plate 14 are connected in sequence to form an integrated bracket 10. The integrated bracket 10 is used to connect with at least one of the cab front suspension, bumper, front underrun protection, steering gear and radiator, thereby connecting with one of the above structures through the integrated bracket 10. By sequentially connecting the first extension section 111, the top plate 13, the second side plate 12, and the bottom plate 14, the structural strength of the integrated bracket 10 can be increased. Furthermore, vehicle components such as the cab front suspension, bumper, front underrun protection, steering gear, and radiator can be installed in any one or any two of the first extension section 111, the second side plate 12, the top plate 13, and the bottom plate 14 as needed. In addition, since the first side plate 11 and the second side plate 12 are spaced apart, and the top plate 13 and the bottom plate 14 are spaced apart, the integrated bracket 10 has an internal cavity 101, which reduces weight. The second extension section 112 is used to connect the longitudinal beams of the frame assembly, thereby connecting the vehicle components to the longitudinal beams of the frame assembly. Moreover, connecting the longitudinal beams of the frame assembly only through the second extension section 112 further simplifies the structure while meeting structural strength requirements.

[0039] Continue to refer to Figures 1-5 The top plate 13 extends rearward and connects to the second extension section 112 to increase the structural strength of the second extension section 112. In this embodiment, the top plate 13 extends to the rear end face of the second extension section 112. The bottom plate 14 extends rearward and connects to the second extension section 112 to increase the structural strength of the second extension section 112. In this embodiment, the bottom plate 14 also extends to the rear end face of the second extension section 112.

[0040] Continue to refer to Figures 1-5The extended beam body 1 also includes a reinforcing plate 15 that is connected to both the top plate 13 and the bottom plate 14. The reinforcing plate 15 is spaced apart from the second extension section 112. Along the front-rear direction of the vehicle body, the reinforcing plate 15 is located behind the second side plate 12. Since the second side plate 12 does not extend to the rear, the structural strength between the top plate 13 and the bottom plate 14 can be increased by setting the reinforcing plate 15.

[0041] Continue to refer to Figures 1-5 The front extension beam of the frame also includes a first steering gear mounting part 21 and a second steering gear mounting part 22. The first steering gear mounting part 21 and the second steering gear mounting part 22 are used to install the steering gear. The first steering gear mounting part 21 is disposed on the second side plate 12, and the second steering gear mounting part 22 is disposed on the reinforcing plate 15, thereby integrating the first steering gear mounting part 21 and the second steering gear mounting part 22 used to install the steering gear into the extension beam body 1.

[0042] Optionally, the base plate 14 is partially bent, and the first side plate 11 and the second side plate 12 have grooves with the openings of the grooves facing downwards. The grooves are located between the first steering gear mounting part 21 and the second steering gear mounting part 22, which can reserve more installation space for the steering gear.

[0043] Continue to refer to Figures 1-5 The extended beam of the frame also includes an extension plate 3 disposed at the front end of the integrated bracket 10. A front lower protection mounting part 31 is disposed on the rear side of the extension plate 3. The front lower protection mounting part 31 is used to install the front lower protection, thereby integrating the front lower protection mounting part 31 for installing the front lower protection into the extended beam body 1. Optionally, the extension plate 3 extends downward so that there is an installation space for installing the front lower protection behind the extension plate 3. In this embodiment, the extension plate 3 is spaced apart from the first steering gear mounting part 21, and the front lower protection is disposed in the gap between the extension plate 3 and the first steering gear mounting part 21.

[0044] Continue to refer to Figures 1-5 The front side of the extension plate 3 is provided with a bumper mounting part 32, which is used to install the bumper, thereby integrating the bumper mounting part 32 for installing the bumper into the extended beam body 1. Optionally, the bumper mounting part 32 includes a first bumper mounting part 321 and a second bumper mounting part 322, both of which are provided on the front side of the extension plate 3 and are spaced apart in the vertical direction to facilitate the installation of the bumper.

[0045] Optionally, the front extension beam of the frame also includes a radiator mount 4 disposed on the integrated bracket 10. The radiator mount 4 can be specifically installed on the top plate 13. The radiator mount 4 is used to install the radiator mount, thereby integrating the radiator mount 4 into the extension beam body 1.

[0046] Optionally, the front extension beam of the chassis also includes a cab front suspension mounting part 5 disposed on the integrated bracket 10. The cab front suspension mounting part 5 can be specifically installed on the roof plate 13. The cab front suspension mounting part 5 is used to install the cab front suspension, thereby integrating the cab front suspension mounting part 5 into the extension beam body 1.

[0047] Optionally, the front extension beam of the frame also includes a pedal mounting portion 6, which is disposed on the second extension section 112 and is used to mount the pedals, thereby integrating the pedal mounting portion 6 into the extension beam body 1. In some embodiments, the longitudinal beam of the frame assembly is fixedly connected to the second extension section 112 by bolts, and the pedals can be connected to the frame assembly by the same bolt, or the longitudinal beam and the pedals can be mounted at different positions on the second extension section 112.

[0048] This embodiment also provides a frame assembly, including the aforementioned front extended beam, two longitudinal beams, and several crossbeams connecting the two longitudinal beams and located between them. A second extension section 112 connects the longitudinal beams. In this front extended beam, by sequentially connecting the first extension section 111, top plate 13, second side plate 12, and bottom plate 14, the structural strength of the integrated bracket 10 can be increased. Furthermore, the vehicle's components can be arranged in any one or any two of the first extension section 111, second side plate 12, top plate 13, and bottom plate 14 according to actual needs. In addition, since the first side plate 11 and second side plate 12 are spaced apart, and the top plate 13 and bottom plate 14 are spaced apart, the integrated bracket 10 has an internal cavity 101, which can reduce weight. The second extension section 112 is used to connect the longitudinal beams of the frame assembly, thereby connecting the vehicle's components to the longitudinal beams of the frame assembly. Furthermore, connecting the longitudinal beams of the frame assembly only through the second extension section 112 further simplifies the structure while meeting structural strength requirements.

[0049] Continue to refer to Figures 1-5 There are two front extension beams for the chassis. The two front extension beams are connected to the two longitudinal beams in a one-to-one correspondence. The first side plate 11 of the two front extension beams is located between the second side plate 12 of the two front extension beams. The cab front suspension, bumper, front underrun protection, steering gear and radiator are installed through the two front extension beams to improve the stability of the connection.

[0050] Continue to refer to Figures 1-5 Along the rear-to-front direction, the first side plate 11 of any frame front extension beam extends away from the other frame front extension beam, thus leaving more space between the two frame front extension beams for mounting structures such as steering gears or engines.

[0051] This embodiment also provides a vehicle, including the aforementioned frame assembly, and further including a cab front mount, bumper, front underrun protection, steering gear, and radiator. An integrated bracket 10 is used to connect to at least one of the cab front mount, bumper, front underrun protection, steering gear, and radiator. This frame assembly can be connected to at least one of the cab front mount, bumper, front underrun protection, steering gear, and radiator via a front frame extension beam. This saves space, simplifies the structure, and ensures that the structural strength of the front frame extension beam meets requirements.

[0052] 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 will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
