Description

Technical Field

[0001] This disclosure relates to the field of automotive parts technology, and more particularly to a chassis and vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, more and more pure electric and range-extended models have emerged. Range-extended models with non-load-bearing body design need to install engine mounts on the vehicle body to achieve engine installation, while pure electric models do not need to install engines. Therefore, existing range-extended models and pure electric models must have separate chassis designs, resulting in a waste of design costs and production line construction costs. Summary of the Invention

[0003] To overcome the problems existing in the related technologies, this disclosure provides a chassis and a vehicle.

[0004] According to a first aspect of the present disclosure, a frame is provided for use in a vehicle employing a non-load-bearing body design. The frame includes a front longitudinal beam and a front upper longitudinal beam. The front longitudinal beam is provided with a first connecting structure. The front upper longitudinal beam is provided with a second connecting structure corresponding to the first connecting structure, and is selectively and detachably connected to the front longitudinal beam via the cooperation of the first connecting structure and the second connecting structure. The front upper longitudinal beam is provided with a mount mounting structure for connecting an engine mount.

[0005] In some exemplary embodiments of this disclosure, the front longitudinal beam is provided with a connecting bracket, and the first connecting structure is disposed on the connecting bracket.

[0006] In some exemplary embodiments of this disclosure, the frame further includes an inner plate of the upper side beam of the front wheel arch; wherein the upper front longitudinal beam is detachably connected to the inner plate of the upper side beam of the front wheel arch.

[0007] In some exemplary embodiments of this disclosure, the inner plate of the upper side beam of the front wheel cover is provided with a third connecting structure, which cooperates with both the first connecting structure and the second connecting structure.

[0008] In some exemplary embodiments of this disclosure, the frame further includes a front shock absorber tower; wherein the front upper longitudinal beam is detachably connected to the front shock absorber tower.

[0009] In some exemplary embodiments of this disclosure, the second connecting structure is disposed at the front end of the front upper longitudinal beam, the front end of the front upper longitudinal beam is connected to the front longitudinal beam, and the rear end of the front upper longitudinal beam is connected to the front shock absorber tower.

[0010] In some exemplary embodiments of this disclosure, the front upper longitudinal beam is a square tubular structure, and the top wall of the square tubular structure is provided with a through hole; the suspension mounting structure is disposed in the cavity of the square tubular structure and includes a suspension mounting bracket and a sleeve nut; the suspension mounting bracket is connected to the tube wall of the square tubular structure; the sleeve nut is connected to the suspension mounting bracket, and the screw hole of the sleeve nut is arranged corresponding to the through hole, so that the engine mount is connected to the suspension mounting structure via a bolt passing through the through hole and screwed into the screw hole.

[0011] In some exemplary embodiments of this disclosure, the front upper longitudinal beam includes an upper part and a lower part; the lower part has a bottom plate and a first side plate that connects to one side of the bottom plate and extends upward; the upper part has a top plate and a second side plate that connects to the other side of the top plate and extends downward; wherein the upper end of the first side plate is connected to one side of the top plate, and the lower end of the second side plate is connected to the other side of the bottom plate.

[0012] According to a second aspect of the present disclosure, a vehicle is provided, the vehicle including the frame proposed in the present disclosure and described in the exemplary embodiments described above.

[0013] In some exemplary embodiments of this disclosure, the vehicle is a range-extended vehicle and includes an engine, the frame is a structure in which the front longitudinal beam is provided with the front upper longitudinal beam, and the engine is connected to the suspension mounting structure via an engine mount; or, the vehicle is a pure electric vehicle, and the frame is a structure in which the front longitudinal beam is not provided with the front upper longitudinal beam.

[0014] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: The vehicle frame proposed in this disclosure includes a front longitudinal beam and a front upper longitudinal beam; the front longitudinal beam is provided with a first connecting structure; the front upper longitudinal beam is provided with a second connecting structure corresponding to the first connecting structure, and the front longitudinal beam is selectively and detachably connected via the cooperation of the first connecting structure and the second connecting structure; the front upper longitudinal beam is provided with a mount mounting structure, which is used to connect the engine mount. Through the above structural design, this disclosure can selectively switch the vehicle frame to a first structural form with the front upper longitudinal beam installed and a second structural form without the front upper longitudinal beam. When the vehicle frame is applied to a range-extended vehicle, this disclosure can use the mount mounting structure of the front upper longitudinal beam to connect the engine mount, thereby connecting the engine, that is, realizing the installation of the engine on the front upper longitudinal beam of the vehicle frame. When the vehicle frame is applied to a pure electric vehicle, since the pure electric vehicle does not have an engine, this disclosure can remove the front upper longitudinal beam to provide more space for the front compartment structure of the vehicle body. Accordingly, this disclosure enables a unified chassis design for different vehicle types, such as range-extended electric vehicles and pure electric vehicles. Only a unified interface needs to be reserved on the chassis to allow for selective installation of the front upper longitudinal beam, greatly facilitating platform sharing across different vehicle types and significantly reducing design and production line construction costs. Furthermore, for range-extended electric vehicles, this disclosure can utilize the front upper longitudinal beam to add a force transmission path, dispersing the energy transferred to the chassis during a collision and improving occupant protection.

[0050] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0051] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0052] See Figure 1 The illustration shows a partial schematic diagram of the frame 100 in a first structural configuration. In this exemplary embodiment, the frame 100 of this disclosure is described as an example applied to a vehicle employing a non-load-bearing body design. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of vehicles, and these changes are still within the scope of the principles of the frame 100 of this disclosure.

[0053] like Figure 1 As shown, in one embodiment of this disclosure, the frame 100 includes a front longitudinal beam 110 and a front upper longitudinal beam 120. (See also...) Figures 2 to 7 , Figure 2 China representatively shows Figure 1 A magnified view of a portion of the image; Figure 3 China representatively shows Figure 2 A schematic diagram of the decomposition process; Figure 4 The diagram shows a representative structural schematic of the front upper longitudinal beam 120; Figure 5 The exploded schematic diagram of the front upper longitudinal beam 120 is shown in the figure. Figure 6 A partial schematic diagram of the frame 100 in the second structural configuration is shown in the figure. Figure 7 The accompanying drawings represent a partial schematic diagram of a portion of the vehicle's structure. The structure, connection methods, and functional relationships of the major components of the frame 100 disclosed herein will be described in detail below, in conjunction with the aforementioned drawings.

[0054] like Figures 1 to 3 , Figure 6 As shown, in one embodiment of this disclosure, the front longitudinal beam 110 is provided with a first connecting structure, which is, for example, but not limited to, the first mounting hole 111 shown in the figures. The front upper longitudinal beam 120 is provided with a second connecting structure corresponding to the first connecting structure, which is, for example, but not limited to, the second mounting hole 121 shown in the figures. Accordingly, the front upper longitudinal beam 120 is selectively and detachably connected to the front longitudinal beam 110 via the cooperation of the first connecting structure and the second connecting structure. For example, the front upper longitudinal beam 120 can be connected to the front longitudinal beam 110 via bolts 113 or other connectors passing through the first mounting hole 111 and the second mounting hole 121. (See also...) Figure 7 The front upper longitudinal beam 120 is provided with a mounting structure 122, which is used to connect the engine mount 200, thereby allowing the engine to be connected to the front upper longitudinal beam 120 via the engine mount 200, thus realizing the engine mounting on the frame 100. Based on this, the frame 100 proposed in this disclosure can selectively switch between a first structural type and a second structural type. In the first structural type, the front longitudinal beam 110 is connected to the front upper longitudinal beam 120; in the second structural type, the front longitudinal beam 110 is not connected to the front upper longitudinal beam 120. Through the above structural design, this disclosure allows for the selective switching of the chassis 100 to a first structural configuration with the front upper longitudinal beam 120 installed and a second structural configuration without the front upper longitudinal beam 120. When the chassis 100 is used in a range-extended vehicle, this disclosure allows for the connection of the engine mount 200 via the suspension mounting structure 122 of the front upper longitudinal beam 120, thereby connecting the engine and enabling the engine to be mounted on the front upper longitudinal beam 120 of the chassis 100. When the chassis 100 is used in a pure electric vehicle, since pure electric vehicles do not have an engine, this disclosure allows for the removal of the front upper longitudinal beam 120, providing more space for the front compartment structure of the vehicle body. Accordingly, this disclosure enables a unified design for the chassis 100 used in different vehicle types, such as range-extended and pure electric vehicles, requiring only a unified interface to be reserved on the chassis 100 to achieve selective installation of the front upper longitudinal beam 120. This greatly facilitates platform sharing among different vehicle types, significantly reducing design and production line construction costs. In addition, for range-extended models, this disclosure can also use the front upper longitudinal beam 120 to add a force transmission path, disperse the energy transmitted to the frame 100 when the vehicle collides, and improve the occupant protection effect.

[0055] like Figure 3 and Figure 6As shown, in one embodiment of this disclosure, the front longitudinal beam 110 may be provided with a connecting bracket 112, and a first connecting structure (e.g., a first mounting hole 111) may be provided on the connecting bracket 112. In other words, the front upper longitudinal beam 120 is connected to the connecting bracket 112 via bolts 113 and is provided on the front longitudinal beam 110 via a connecting assembly. Through the above structural design, this disclosure uses a connecting assembly to connect the front upper longitudinal beam 120, which facilitates the assembly and disassembly of the front upper longitudinal beam 120 and avoids affecting its structural strength by directly setting the first mounting hole 111 on the front longitudinal beam 110.

[0056] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the vehicle frame 100 further includes an inner plate 130 for the upper side beam of the front wheel arch. Based on this, the upper front longitudinal beam 120 can be detachably connected to the inner plate 130 for the upper side beam of the front wheel arch. Through the above structural design, this disclosure enables a more stable installation of the upper front longitudinal beam 120 in the vehicle frame 100, thereby ensuring the stability and reliability of the engine's installation and operation.

[0057] like Figure 3 As shown, based on the structural design of the frame 100 including the inner plate 130 of the upper side beam of the front wheel arch, in one embodiment of this disclosure, the inner plate 130 of the upper side beam of the front wheel arch may be provided with a third connecting structure. This third connecting structure simultaneously cooperates with the first connecting structure of the front longitudinal beam 110 (e.g., connecting bracket 112) and the third connecting structure of the front upper longitudinal beam 120. For example, when the first connecting structure is the first mounting hole 111 and the second connecting structure is the second mounting hole 121, the third connecting structure can be the third mounting hole 131, and the front longitudinal beam 110 (e.g., connecting bracket 112), the front upper longitudinal beam 120, and the inner plate 130 of the upper side beam of the front wheel arch can be connected together via bolts 113 passing through the first mounting hole 111, the second mounting hole 121, and the third mounting hole 131. Furthermore, as... Figure 6 As shown, when the frame 100 is in the second structural configuration, the inner plate 130 of the upper side beam of the front wheel arch can still be connected to the connecting bracket 112, thereby connecting to the front longitudinal beam 110 via the connecting bracket 112. Through the above structural design, this disclosure can utilize shared connection point design to simultaneously achieve the connection between the upper front longitudinal beam 120 and the front longitudinal beam 110 and the inner plate 130 of the upper side beam of the front wheel arch. While ensuring the connection effect, this helps to reduce the structural complexity of the components and simplify the assembly process. In other embodiments of this disclosure, to achieve the connection between the upper front longitudinal beam 120 and the inner plate 130 of the upper side beam of the front wheel arch, other connection structures different from the second connection structure can also be additionally provided on the upper front longitudinal beam 120, and this is not limited to this embodiment.

[0058] like Figure 1 , Figure 2 and Figure 4As shown, in one embodiment of this disclosure, the vehicle frame 100 further includes a front shock absorber tower 140. Based on this, the front upper longitudinal beam 120 can be detachably connected to the front shock absorber tower 140, for example, by hot melt rotary tapping and riveting (FDS). Through the above structural design, this disclosure enables a more stable installation of the front upper longitudinal beam 120 in the vehicle frame 100, thereby ensuring the stability and reliability of the engine's installation and operation.

[0059] like Figure 2 and Figure 4 As shown, based on the structural design of the frame 100 including the front shock absorber tower 140, in one embodiment of this disclosure, the front shock absorber tower 140 may be provided with a fourth connecting structure (not shown in the figures), and the front upper longitudinal beam 120 may be provided with a fifth connecting structure corresponding to the fourth connecting structure. For example, the fourth connecting structure and the fifth connecting structure may each be a mounting hole, such as the fifth connecting structure being the fourth mounting hole 123 shown in the figures, and the front shock absorber tower 140 and the front upper longitudinal beam 120 may be connected together via hot-melt rotary tapping and riveting (not shown in the figures) or bolts or other connecting members provided in the fourth mounting hole 123.

[0060] like Figure 1 and Figure 2 As shown, based on the structural design of the front upper longitudinal beam 120 connecting the front shock absorber tower 140, in one embodiment of this disclosure, the second connecting structure can be set at the front end of the front upper longitudinal beam 120, that is, the front end of the front upper longitudinal beam 120 is connected to the front longitudinal beam 110, specifically connected to the connecting bracket 112, and the rear end of the front upper longitudinal beam 120 is connected to the front shock absorber tower 140.

[0061] like Figure 3 As shown, in one embodiment of this disclosure, the front longitudinal beam 110 may include a front section 114 and a rear section 115, with the front section 114 detachably connected to the rear section 115 via bolts 116. Furthermore, the front upper longitudinal beam 120 may be connected to the front section 114 of the front longitudinal beam 110.

[0062] like Figure 4 and Figure 5As shown, in one embodiment of this disclosure, the front upper longitudinal beam 120 can be a square tubular structure, and the top wall of the square tubular structure (e.g., the top plate 1261 described below) is provided with a through hole 124. A suspension mounting structure 122 is disposed within the cavity of the square tubular structure, and the suspension mounting structure 122 includes a suspension mounting bracket 1221 and a sleeve nut 1222. The suspension mounting bracket 1221 is connected to the wall of the square tubular structure. The sleeve nut 1222 is connected to the suspension mounting bracket 1221, and the screw hole of the sleeve nut 1222 is arranged corresponding to the through hole 124, so that the engine mount 200 can be connected to the suspension mounting structure 122 via a bolt (not shown in the figures) passing through the through hole 124 and screwed into the screw hole. Through the above structural design, the front upper longitudinal beam 120 adopts a hollow square tube structure, which can further reduce the weight of the frame 100. At the same time, the sleeve nut 1222 is used to achieve a reliable connection between the suspension mounting structure 122 and the engine mount 200, and it is easy to disassemble.

[0063] like Figure 4 and Figure 5 As shown, based on the structural design of the front upper longitudinal beam 120 as a square tubular structure, in one embodiment of this disclosure, the front upper longitudinal beam 120 may include an upper part 126 and a lower part 125. The lower part 125 has a bottom plate 1251 and a first side plate 1252 that connects to one side of the bottom plate 1251 and extends upward. The upper part 126 has a top plate 1261 and a second side plate 1262 that connects to the other side of the top plate 1261 and extends downward. The upper end of the first side plate 1252 is connected to one side of the top plate 1261, and the lower end of the second side plate 1262 is connected to the other side of the bottom plate 1251.

[0064] Based on the structural design of the front upper longitudinal beam 120, which includes an upper part 126 and a lower part 125, in one embodiment of this disclosure, the upper part 126 and the lower part 125 can be fixedly connected by welding. For example, the bottom plate 1251 and the first side plate 1252 are integral structures, and the top plate 1261 and the second side plate 1262 are integral structures. On this basis, the upper end of the first side plate 1252 is welded to the top plate 1261, and the lower end of the second side plate 1262 is welded to the bottom plate 1251.

[0065] Based on the structural design of the front upper longitudinal beam 120 as a square tubular structure with a suspension mounting structure 122 installed inside the cavity, in one embodiment of this disclosure, the suspension mounting bracket 1221 can be welded to the wall of the square tubular structure. For example, the suspension mounting bracket 1221 shown in the attached drawings has welding lugs facing the top plate 1261 and the first side plate 1252 respectively, thereby enabling it to be welded to the first part. Of course, the suspension mounting bracket 1221 can also be welded to the second part. Furthermore, the sleeve nut 1222 can be welded to the suspension mounting bracket 1221.

[0066] like Figure 4 and Figure 5 As shown, in one embodiment of this disclosure, the front upper longitudinal beam 120 may be provided with two suspension mounting structures 122, which are arranged at intervals along the extending direction of the front upper longitudinal beam 120. Correspondingly, the top wall of the front upper longitudinal beam 120 (e.g., the top plate 1261 mentioned above) may be provided with two through holes 124. In other embodiments of this disclosure, the number of suspension mounting structures 122 may be one, three, or more, which can be adjusted according to the specific connection structure of the engine mount 200.

[0067] It should be noted that the frame 100 shown in the accompanying drawings and described in this specification is merely a few examples among many frames 100 capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the frame 100 shown in the accompanying drawings or described in this specification.

[0068] Based on the above detailed description of several exemplary embodiments of the frame 100 proposed in this disclosure, an exemplary embodiment of the frame 100 proposed in this disclosure will be described below.

[0069] In one embodiment of this disclosure, the vehicle proposed in this disclosure includes the frame 100 proposed in this disclosure and described in detail in the above embodiments.

[0070] like Figure 1 and Figure 7 As shown, in one embodiment of this disclosure, the vehicle proposed in this disclosure is a range-extended vehicle, and the range-extended vehicle includes an engine. The frame 100 can be a first structural configuration, namely, a configuration in which a front upper longitudinal beam 120 is provided on the front longitudinal beam 110, and the engine is connected to the suspension mounting structure 122 of the front upper longitudinal beam 120 via an engine mount 200.

[0071] like Figure 6 As shown, in one embodiment of this disclosure, the vehicle proposed in this disclosure is a pure electric vehicle, and the frame 100 is a second structural type, that is, a structural type in which the front upper longitudinal beam 120 is not provided on the front longitudinal beam 110.

[0072] It should be noted that the vehicles shown in the accompanying drawings and described in this specification are merely a few examples among many vehicles capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the vehicles shown in the accompanying drawings or described in this specification.

[0073] In summary, the technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: the frame 100 proposed in this disclosure includes a front longitudinal beam 110 and a front upper longitudinal beam 120; the front longitudinal beam 110 is provided with a first connecting structure; the front upper longitudinal beam 120 is provided with a second connecting structure corresponding to the first connecting structure, and is selectively and detachably connected to the front longitudinal beam 110 via the cooperation of the first connecting structure and the second connecting structure; the front upper longitudinal beam 120 is provided with a suspension mounting structure 122, which is used to connect the engine mount 200. Through the above structural design, this disclosure allows for the selective switching of the chassis 100 to a first structural configuration with the front upper longitudinal beam 120 installed and a second structural configuration without the front upper longitudinal beam 120. When the chassis 100 is used in a range-extended vehicle, this disclosure allows for the connection of the engine mount 200 via the suspension mounting structure 122 of the front upper longitudinal beam 120, thereby connecting the engine and enabling the engine to be mounted on the front upper longitudinal beam 120 of the chassis 100. When the chassis 100 is used in a pure electric vehicle, since pure electric vehicles do not have an engine, this disclosure allows for the removal of the front upper longitudinal beam 120, providing more space for the front compartment structure of the vehicle body. Accordingly, this disclosure enables a unified design for the chassis 100 used in different vehicle types, such as range-extended and pure electric vehicles, requiring only a unified interface to be reserved on the chassis 100 to achieve selective installation of the front upper longitudinal beam 120. This greatly facilitates platform sharing among different vehicle types, significantly reducing design and production line construction costs.

[0074] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0075] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0076] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

[0077] It should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., used in the embodiments of this disclosure 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, an electrical connection, or a connection that allows communication between them; 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein according to the specific circumstances.

[0078] Although terms such as “first” and “second” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0079] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
