[0029] With the continuous development of new energy vehicles, in order to meet the travel needs of different groups, the power direction of new energy vehicles is divided into pure electric power or range-extended power. Among them, range-extended vehicles need to accommodate multiple components such as engines, batteries, and fuel tanks, resulting in smaller batteries and thus the technical problem of frequent charging.

[0030] To address the aforementioned technical problems, this application provides a chassis assembly for range-extended vehicles, see reference.

[0031] The frame assembly 10 includes a first sill beam assembly 110, an exhaust assembly 130, and a battery tray 120. The first sill beam assembly 110 has a mounting cavity 114. The exhaust assembly 130 includes a first exhaust member 131, a second exhaust member 132, and a third exhaust member 133 that are interconnected; the first exhaust member 131 is configured to connect to the second exhaust member 132 and the third exhaust member 133, the second exhaust member 132 is configured to connect to the vehicle's engine, and the third exhaust member 133 is configured to connect to the outside air. The exhaust assembly 130 is configured to connect to the vehicle's engine and discharge the gases generated by the engine sequentially through the second exhaust member 132, the first exhaust member 131, and the third exhaust member 133 to the external environment of the vehicle.

[0032] The battery tray 120 is connected to the first door sill beam assembly 110. The battery tray 120 includes a body 121 and a flange surface 122 surrounding the periphery of the body 121. A first vent 131 is at least partially disposed in the mounting cavity 114, and a second vent 132 is disposed on the side of the flange surface 122 facing away from the interior of the vehicle.

[0033] Understandably, the first exhaust member 131 of this application is at least partially disposed within the mounting cavity 114 and integrated with the first sill beam assembly 110, which reduces the space occupied by the first exhaust member 131 at the bottom of the vehicle, thereby increasing the space available for the vehicle's battery. Furthermore, the second exhaust member 132 is disposed on the flange surface 122 of the battery tray 120, making the arrangement of the second exhaust member 132 and the battery tray 120 more compact, further increasing the space available for the vehicle's battery. In other words, the frame assembly 10 provided by this application can increase the space available for the vehicle's battery, thereby increasing the battery's capacity and improving the problem of frequent battery charging. In addition, the integration of the first exhaust member 131 with the first sill beam assembly 110 allows for a coupled design between the first exhaust member 131 and the frame assembly 10, enabling the first exhaust member 131 to participate in the vehicle's side pillar collision, thus improving vehicle body performance.

[0034] In one embodiment, the exhaust assembly 130 further includes a connector 134, which is configured to connect the first exhaust member 131 and the second exhaust member 132, or to connect the first exhaust member 131 and the third exhaust member 133. The connector 134 includes two interconnected through holes (not shown in the figure), the central axes of which are perpendicular to each other.

[0035] In one embodiment, the battery tray 120 has a vertical length direction and a width direction. A first vent 131 is located on one side of the battery tray 120 in the length direction, and a flange face 122 with a second vent 132 is located on one side of the battery tray 120 in the width direction. The length direction of the battery tray 120 refers to its direction along the length of the vehicle, and the width direction refers to its direction along the width of the vehicle. Understandably, in this embodiment, the first exhaust 131 is located in the length direction of the vehicle and on one side of the battery tray 120, which can reduce the heat transfer of the first exhaust 131 to the battery tray 120, thereby reducing the impact of the first exhaust 131 on the battery pack located in the battery tray 120. In addition, the flange face 122 of the second exhaust 132 is located on one side of the battery tray 120 in the width direction, that is, the first exhaust 131 and the second exhaust 132 are arranged along the edge of the battery tray 120, so that the arrangement of the first exhaust 131, the second exhaust 132 and the battery tray 120 is more compact, which can make full use of the bottom space of the vehicle, increase the battery arrangement space of the vehicle, and improve the problem of frequent battery movement.

[0036] In one embodiment, the frame assembly 10 further includes a first isolator 140 and a second isolator (not shown in the figure). The first isolator 140 surrounds the portion of the first exhaust 131 located in the mounting cavity 114. The first isolator 140 is configured at least to isolate heat from the first exhaust 131 and may also be configured to isolate noise. The second isolator is located between the outer wall of the first isolator 140 and the cavity wall of the mounting cavity 114. The second isolator is configured at least to isolate noise from the second exhaust 132 and may also be configured to isolate heat. Understandably, the first isolator 140 in this embodiment can isolate heat from the first exhaust 131, reducing heat transfer to the battery tray 120 and minimizing its impact on the battery. Furthermore, the second isolator can isolate noise from the first exhaust 131, improving the vehicle's NVH (noise, vibration, and harshness) and enhancing the user experience.

[0037] In one embodiment, the first insulating element 140 may be a glass fiber insulating material, ceramic fiber, or aerogel insulation cotton, etc. Preferably, the first insulating element 140 in this embodiment is aerogel insulation cotton, which has the advantages of occupying little space, having good thermal insulation performance, and having a long service life.

[0038] In one embodiment, the second insulating member includes a heat-insulating adhesive. Specifically, the heat-insulating adhesive can be an adhesive with heat-insulating and fixing functions, and is not limited thereto. The heat-insulating adhesive can fill the gap between the first insulating member 140 and the cavity wall of the mounting cavity 114, and can further insulate the heat, while also having the function of vibration reduction and sound insulation, which can improve the vibration and noise problems of the exhaust assembly 130.

[0039] In one embodiment, the frame assembly 10 further includes a third insulating member (not shown in the figure), which is disposed around the periphery of the second exhaust member 132. The third insulating member is configured at least to insulate against heat. That is, the third insulating member in this embodiment can reduce the heat transfer from the second exhaust member 132 to the battery tray 120, thereby reducing the impact of the second exhaust member 132 on the vehicle battery. The specific structure of the third insulating member may be the same as or different from that of the second insulating member, and is not limited thereto.

[0040] In one embodiment, the first sill beam assembly 110 includes an upper sill beam 111 and a lower sill beam 112. The lower sill beam 112 is disposed on the side of the upper sill beam 111 facing away from the interior of the vehicle, and together with the upper sill beam 111, forms a mounting cavity 114. A first through hole is formed on the side of the lower sill beam 112 facing away from the interior of the vehicle, and the first exhaust component 131 extends out of the mounting cavity 114 through the first through hole. It can be understood that the first sill beam assembly 110 of this embodiment includes an upper sill beam 111 and a lower sill beam 112, that is, the first sill beam assembly 110 is a split structure, which facilitates the installation of the first exhaust component 131.

[0041] In one embodiment, the first sill beam assembly 110 further includes an end plate 113, which is disposed at the end of the first sill beam assembly 110 in the length direction of the vehicle and connected to the upper sill beam 111 and the lower sill beam 112 to seal the mounting cavity 114. The end plate 113 is a flat plate structure. In this embodiment, by providing the end plate 113 to seal the mounting cavity 114, the first sill beam assembly 110 can reduce noise and minimize the entry of foreign objects into the mounting cavity 114.

[0042] In one embodiment, the lower sill beam 112 includes a first connecting portion 1121 and a second connecting portion 1122, both of which are configured to connect to the upper sill beam 111, wherein the first connecting portion 1121 and the second connecting portion 1122 are arranged vertically. It can be understood that the connection between the lower sill beam 112 and the upper sill beam 111 in this embodiment is "L"-shaped. This structure results in a larger opening in the upper sill beam 111, facilitating the entry of the first vent 131 into the interior of the upper sill beam 111 through the opening.

[0043] The upper sill beam 111 and the lower sill beam 112 are assembled to form the first sill beam assembly 110. The first sill beam assembly 110 has a multi-cavity structure. The front and rear ends of the first sill beam assembly 110 are fixed to the castings of the front lower crossbeam assembly and the rear floor front crossbeam assembly by bolts and FDS nails. The middle section of the first sill beam assembly 110 is mainly matched with the side wall assembly and fixed by FDS nails. The nails penetrate into the cavity of the first sill beam assembly 110 from the outside.

[0044] In one embodiment, the first sill beam assembly 110 has end plates 113 at both its front and rear ends. One end plate 113 has a Φ15 circular hole. After the first exhaust component 131 and the first isolator 140 are assembled into the mounting cavity 114, the mounting cavity 114 is sealed by the end plate 113. After sealing, a tubular injection device is extended to the other end through the Φ15 circular hole on one end of the sealing plate using a tooling, and then slowly removed backward while injecting heat insulation adhesive. The heat insulation adhesive will fill all the gaps between the first isolator 140 and the cavity wall of the mounting cavity 114. The heat insulation adhesive is a self-drying adhesive. After curing, the mounting cavity 114 is completely filled. The heat insulation adhesive can further insulate heat and also has vibration reduction and sound insulation effects, solving the vibration and noise problems of the exhaust component 130.

[0045] In one embodiment, the frame assembly 10 further includes a second sill beam assembly (not shown) and a body frame assembly 150. The first sill beam assembly 110 and the second sill beam assembly are spaced apart along the width direction of the vehicle, and the body frame assembly 150, the first sill beam assembly 110, and the second sill beam assembly together form a sealing surface 151, which faces away from the interior of the vehicle. The sealing surface 151 is fixedly connected to a flange surface 122. Understandably, in this embodiment, the first sill beam assembly 110, the second sill beam assembly, and the body frame assembly 150 together form the sealing surface 151 on the side facing away from the interior of the vehicle. The sealing surface 151 is sealed to the battery tray 120, thereby coupling the vehicle's battery pack with the frame assembly 10 and improving the overall rigidity of the vehicle.

[0046] In one embodiment, the vehicle frame assembly 150 includes a front lower crossbeam assembly (not shown) and a front floor lower crossbeam assembly (not shown). The front floor lower crossbeam assembly extends curvedly at both ends in the width direction of the vehicle to corresponding first sill beam assemblies 110 or second sill beam assemblies, and together with the front lower crossbeam assembly, the first sill beam assembly 110, and the second sill beam assembly, their curvatures continuously enclosing the side of the assembly facing away from the vehicle interior to form a sealing surface 151. Understandably, in this embodiment, the front lower crossbeam assembly, the front floor lower crossbeam assembly, the first sill beam assembly 110, and the second sill beam assembly constitute a sealing cover for the battery, and together form the sealing surface 151 on the side facing the battery tray 120. The sealing surface 151 is fitted against the flange surface 122 of the battery tray 120 to seal the battery.

[0047] Specifically, the frame assembly 10 has a three-horizontal and two-vertical structure. The three horizontal components are primarily the front lower crossbeam assembly of the body frame assembly 150, the rear floor front crossbeam assembly (not shown in the figure), and the front floor lower crossbeam assembly. The front lower crossbeam assembly is a one-piece die-cast structure, as is the rear floor front crossbeam assembly, while the front floor lower crossbeam assembly is a sheet metal structure arranged laterally. The two vertical components are the first sill beam assembly 110 and the second sill beam assembly, both of which are extruded aluminum profiles arranged in a front-rear direction. The two ends of the front lower crossbeam assembly curve rearward, while the middle section is lower than the two ends. The two ends of the rear floor front crossbeam assembly are curved forward, and the two ends of the front floor lower crossbeam are also curved forward to the first and second sill beam assemblies. Together with the lower crossbeam assembly of the front bulkhead and the lower bottom surface curvature of the first and second sill beam assemblies, they form an elliptical racetrack structure. This elliptical racetrack structure is the sealing surface 151 of the battery tray 120. Nut holes are evenly provided on the bottom surface of the sealing surface 151. The battery tray 120 is fixed to the vehicle frame with bolts.

[0048] The first exhaust component 131 is housed within the mounting cavity 114. The first exhaust component 131 has an overall 'n'-shaped arch structure. The front of the arch is located at the Y-axis connection point between the vehicle's front lower crossbeam assembly and the first sill beam assembly 110, while the rear of the arch is located behind the battery, on the side corresponding to the vehicle's fuel tank. The cross-section of the first exhaust component 131 is oval-shaped, with both ends of the arch structure pointing vertically downwards and featuring flange mounting structures. The flange mounting surface is 10mm from the bottom surface of the first sill beam assembly 110 in the Z-axis direction. The arch-shaped first exhaust component 131 is a one-piece molded structure made of high-strength steel with a closed cross-section. After being assembled with the first sill beam assembly 110, it participates in the vehicle collision. The outer side of the first exhaust component 131 is covered with 15mm thick aerogel insulation cotton.

[0049] In one embodiment, the first sill beam assembly 110 has the same structure as the second sill beam assembly, which can reduce the development time of the second sill beam assembly. In other embodiments, the first sill beam assembly 110 has a different structure from the second sill beam assembly, and the second sill beam assembly can be an existing sill beam assembly, which is not limited here.
