Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a suspension mounting assembly, engine compartment, and vehicle. Background Technology

[0002] The suspension mount is a key component of a vehicle used to connect the body and frame. Taking off-road vehicles as an example, the body and frame are generally connected by suspension mounts. Off-road vehicles require both off-road performance and comfort, so the rigidity design of the suspension mount mounting points is crucial.

[0003] The engine compartment of an off-road vehicle typically has a primary mounting point. Currently, the conventional engine compartment design for off-road vehicles is a sheet metal design, meaning that multiple sheet metal parts are welded together to form an engine compartment assembly, and the location of the primary mounting point is also a splicing of multiple sheet metal parts.

[0004] Because the suspension needs to be connected to multiple sheet metal parts at the first suspension mounting point, the installation rigidity of the suspension mounting point is low, resulting in poor connection stability between the suspension and the vehicle body. Summary of the Invention

[0005] This invention provides a suspension mounting assembly, an engine compartment, and a vehicle to solve the problem that the suspension needs to be connected to multiple sheet metal parts at the first suspension mounting point, resulting in low mounting stiffness at the suspension mounting point and poor connection stability between the suspension and the vehicle body.

[0006] This invention provides a suspension mounting assembly, comprising:

[0007] The first finger beam is a square tubular structure. The first end of the first finger beam is provided with a target connection part, which includes a first side wall, a second side wall, a third side wall and a fourth side wall connected end to end in sequence.

[0008] The lower crossbeam of the water tank is a square tubular structure, and the first end of the lower crossbeam of the water tank is parallel to the first side wall and is attached to the first side wall.

[0009] The first column is a square tubular structure, and the first end of the first column is perpendicular to the second side wall and connected to the second side wall.

[0010] The suspension extends sequentially through the fourth sidewall and the second sidewall and connects to the target connection portion.

[0011] Optionally, the fourth sidewall is provided with a first through hole, and the second sidewall is provided with a second through hole corresponding to the first through hole. The suspension passes through the first through hole and the second through hole in sequence and is connected to the target connection part.

[0012] Optionally, the suspension mounting assembly further includes a mounting sleeve located within the target connection portion. The outer wall of the mounting sleeve is connected to the inner wall of the first through hole and the inner wall of the second through hole, respectively. The suspension penetrates the mounting sleeve and is connected to the mounting sleeve.

[0013] Optionally, the suspension includes:

[0014] The suspension body is provided with a connection channel;

[0015] A suspension bolt passes through the connecting channel and is threadedly connected to the mounting sleeve to clamp and fix the suspension body.

[0016] Optionally, the suspension mounting assembly further includes a first connecting plate, which includes a first side and a second side disposed opposite to each other. The first side is respectively attached to the first end of the first column and the first side wall, and the second side is attached to the first end of the lower crossbeam of the water tank.

[0017] Optionally, the suspension mounting assembly further includes a second connecting plate, which includes a first end and a second end disposed opposite to each other. The first end of the second connecting plate is respectively attached to the first end of the first column and the third side wall, and the second end of the second connecting plate is bent to form a bent portion, which is attached to the fourth side wall.

[0018] Optionally, the bent portion is provided with a third through hole corresponding to the first through hole, and the suspension passes through the third through hole, the first through hole and the second through hole in sequence and is connected to the target connection portion.

[0019] Optionally, the bent portion is also fitted and connected to the first end of the lower crossbeam of the water tank.

[0020] This invention also provides an engine compartment, including a second finger beam, a water tank upper crossbeam, and the aforementioned suspension mounting assembly. The second finger beam is connected to the water tank upper crossbeam, and at least one of the second finger beam and the water tank upper crossbeam is connected to the second end of the first column.

[0021] This invention also provides a vehicle that includes the engine compartment described above.

[0022] In this embodiment, the suspension is connected to the target connection part, which is equivalent to the suspension mounting point being located on this single part. Since the target connection part itself is a whole, there are no breaks or structural defects in the force transmission process, resulting in smoother force transmission. This improves the overall performance of the suspension mounting assembly, reduces the number of parts, lowers costs, and simultaneously increases the installation rigidity of the suspension mounting point.

[0030] like Figures 1-3 As shown, an embodiment of the present invention provides a suspension mounting assembly, including:

[0031] The first finger beam 10 is a square tubular structure. The first end of the first finger beam 10 is provided with a target connection part 101. The target connection part 101 includes a first side wall, a second side wall, a third side wall and a fourth side wall connected end to end in sequence.

[0032] The lower crossbeam 20 of the water tank is a square tubular structure. The first end of the lower crossbeam 20 is parallel to the first side wall and is attached to the first side wall.

[0033] The first column 30 is a square tubular structure, and the first end of the first column 30 is perpendicular to the second side wall and connected to the second side wall.

[0034] Suspension 40, which passes through the fourth sidewall and the second sidewall in sequence and is connected to the target connection part 101.

[0035] The suspension mounting assembly provided in this embodiment of the invention can be applied to vehicles. Furthermore, the suspension mounting assembly provided in this embodiment of the invention can be applied to the engine compartment of an off-road vehicle. For ease of description, the following explanation will take the scenario of the suspension mounting assembly provided in this embodiment of the invention being applied to the engine compartment of an off-road vehicle as an example.

[0036] Please see Figure 1 The first finger beam 10, the lower crossbeam 20 of the water tank, and the first column 30 are all square tubular structures with hollow interiors, resulting in a lighter weight for these components. This design reduces the weight of the suspension mounting assembly and lowers costs.

[0037] In related technologies, the suspension mounting point is composed of multiple sheet metal parts, which results in a large number of parts, high cost, low rigidity, and complex installation procedures. However, in this embodiment, the suspension 40 is connected to the target connection 101, meaning the suspension mounting point is located on this single part. Since the target connection 101 is a single unit, there are no breaks or structural defects in the force transmission process, resulting in smoother force transmission. This improves the overall performance of the suspension mounting assembly, reduces the number of parts, lowers costs, and simultaneously increases the installation rigidity at the mounting point of the suspension 40.

[0038] like Figure 1 As shown, a three-dimensional spatial coordinate system is established with the connection center point between the suspension 40 and the target connection part 101 as the origin. The structural design of the target connection part 101, the first end of the lower crossbeam 20 of the water tank and the first end of the first column 30 forms a triangular support at the connection point. The structure of the triangular support has high stability. Through the above structural design, the installation stiffness in the X, Y and Z directions at the suspension installation point is increased in three-dimensional space.

[0039] The first end of the lower crossbeam 20 of the water tank is parallel to the target connection portion 101. More specifically, the first end of the lower crossbeam 20 of the water tank is parallel to the first sidewall of the target connection portion 101. Since the lower crossbeam 20 of the water tank is a square tubular structure, in specific implementation, the sidewall of the lower crossbeam 20 of the water tank is fitted against and connected to the first sidewall, and the specific connection method is not limited here. Exemplarily, in some embodiments, the sidewall of the lower crossbeam 20 of the water tank is welded and fixed to the first sidewall.

[0040] The first end of the first column 30 is perpendicular to the target connection portion 101. More specifically, the first end of the first column 30 is perpendicular to the second sidewall of the target connection portion 101, and the end face of the first end of the first column 30 is attached to and connected to the second sidewall; the specific connection method is not limited here. Exemplarily, in some embodiments, the end face of the first end of the first column 30 is welded and fixed to the second sidewall.

[0041] In this embodiment, the connection method between the suspension 40 and the target connection portion 101 is not limited. Exemplarily, in some embodiments, the suspension 40 and the target connection portion 101 are welded together. In other embodiments, the suspension 40 and the target connection portion 101 are detachably connected.

[0042] Optionally, in some embodiments, the fourth sidewall is provided with a first through hole, the second sidewall is provided with a second through hole corresponding to the first through hole, and the suspension 40 passes through the first through hole and the second through hole in sequence and is connected to the target connection part 101.

[0043] The first through hole and the second through hole are the same size and coaxially arranged. The suspension 40 passes through the first through hole and the second through hole in sequence and is connected to the target connection part 101. In some embodiments, the suspension 40 is connected to the target connection part 101 by connecting to the inner wall of the first through hole and the inner wall of the second through hole.

[0044] like Figure 2 and Figure 3 As shown, since the first column 30 is hollow inside, in some embodiments, the suspension 40 passes through the first through hole and the second through hole of the target connection portion 101 in sequence, and the latter part is located inside the first column 30. This arrangement provides some protection for the suspension 40, preventing it from becoming loose or displaced due to external force.

[0045] Optionally, in some embodiments, the suspension mounting assembly further includes a mounting sleeve 50 located within the target connection portion 101. The outer wall of the mounting sleeve 50 is connected to the inner wall of the first through hole and the inner wall of the second through hole, respectively. The suspension 40 passes through the mounting sleeve 50 and is connected to the mounting sleeve 50.

[0046] The connection method between the outer wall of the mounting sleeve 50 and the inner walls of the first through hole and the second through hole is not limited here. Exemplarily, in some embodiments, the outer wall of the mounting sleeve 50 is welded to the inner wall of the first through hole, and the outer wall of the mounting sleeve 50 is welded to the inner wall of the second through hole. In some embodiments, the mounting sleeve 50 is pre-welded into the target connection portion 101.

[0047] In this embodiment, a mounting sleeve 50 is provided inside the target connection portion 101. The suspension 40 passes through the mounting sleeve 50 and is connected to the target connection portion 101 through the mounting sleeve 50. By providing the mounting sleeve 50, on the one hand, the contact area between the suspension 40 and the mounting sleeve 50 is increased, thereby improving the connection stability between the suspension 40 and the mounting sleeve 50. On the other hand, by providing the mounting sleeve 50, the connection methods between the suspension 40 and the mounting sleeve 50 are made more diverse, thereby improving the flexibility of the connection method.

[0048] Optionally, in some embodiments, the suspension 40 includes:

[0049] Suspension body 401, wherein the suspension body 401 is provided with a connection channel;

[0050] Suspension bolt 402 passes through the connection channel and is threadedly connected to the mounting sleeve 50 to clamp and fix the suspension body 401.

[0051] Please see Figure 3 The suspension 40 includes a suspension body 401 and a suspension bolt 402. The suspension body 401 has a connecting channel extending through it. The head size of the suspension bolt 402 is larger than the port size of the connecting channel, thereby locking the suspension body 401 in place and preventing it from falling off. The mounting sleeve 50 has a threaded structure that matches the suspension bolt 402. The suspension bolt 402 passes through the connecting channel and is screwed onto the mounting sleeve 50, where it is threadedly connected, so that the suspension body 401 is clamped and fixed between the target connection portion 101 and the head of the suspension bolt 402.

[0052] In this embodiment, the suspension 40 includes a suspension body 401 and a suspension bolt 402. The suspension body 401 has a connecting channel; the suspension bolt 402 passes through the connecting channel and is threadedly connected to the mounting sleeve 50 to clamp and fix the suspension body 401. This design improves both the ease of disassembly and installation between the suspension 40 and the mounting sleeve 50, and enhances the connection stability between them.

[0053] Optionally, in some embodiments, the suspension mounting assembly further includes a first connecting plate 60, which includes a first side and a second side disposed opposite to each other. The first side is respectively attached to the first end of the first column 30 and the first side wall, and the second side is attached to the first end of the lower crossbeam 20 of the water tank.

[0054] The first side of the first connecting plate 60 is fitted and connected to the first end of the first column 30 and the first sidewall of the target connecting part 101. Please refer to Figures 1-3 The first column 30 is a square tubular structure. One side wall of the first end of the first column 30 is on the same plane as the first side wall. The first side of the first connecting plate 60 is parallel to this plane, so that the first side of the first connecting plate 60 is simultaneously attached to and connected to the side wall of the first end of the first column 30 and the first side wall.

[0055] Because the first column 30 is hollow, the contact area between the end face of the first end of the first column 30 and the second side wall of the target connection portion 101 is small. The contact area between the side wall of the first end of the first column 30 and the first side surface of the first connecting plate 60 is large. By connecting both the first end of the first column 30 and the second side wall of the target connection portion 101 to the first connecting plate 60, the connection stability between the first end of the first column 30 and the target connection portion 101 can be improved, thereby increasing the installation rigidity at the suspension mounting point.

[0056] Please see Figures 1-3 The first connecting plate 60 is located between the target connecting part 101 and the lower crossbeam 20 of the water tank. The first side wall of the target connecting part 101 and the side wall of the first end of the lower crossbeam 20 of the water tank are fixedly connected by the first connecting plate 60. By setting the first connecting plate 60, the target connecting part 101, the lower crossbeam 20 of the water tank and the first column 30 are fixed together, further improving the connection stability of the suspension mounting assembly.

[0057] Optionally, in some embodiments, the suspension mounting assembly further includes a second connecting plate 70, the second connecting plate 70 having a first end and a second end disposed opposite to each other, the first end of the second connecting plate 70 being respectively fitted and connected to the first end of the first column 30 and the third side wall, the second end of the second connecting plate 70 being bent to form a bent portion 701, the bent portion 701 being fitted and connected to the fourth side wall.

[0058] One side of the first end of the second connecting plate 70 is in contact with both the first end of the first column 30 and the first sidewall of the target connecting portion 101. The other sidewall of the first end of the first column 30 is in the same plane as the third sidewall of the target connecting portion 101. One side of the first end of the second connecting plate 70 is parallel to both the sidewall and the third sidewall of the first end of the first column 30, so that one side of the first end of the second connecting plate 70 is simultaneously in contact with and connected to both the sidewall and the third sidewall of the first end of the first column 30.

[0059] The second end of the second connecting plate 70 is bent to form a bent portion 701. The included angle between the first end of the second connecting plate 70 and the bent portion 701 can be set and adjusted according to actual conditions. Figure 3 As shown, the second connecting plate 70 is L-shaped.

[0060] The bent portion 701 is located on the side of the target connection portion 101 away from the first column 30, that is, the bent portion 701 is attached to and connected to the fourth side wall of the target connection portion 101. In this embodiment, since the second connecting plate 70 is an integral structure, by fixing the second connecting plate 70, the target connection portion 101 and the first column 30 together, the connection stability of the suspension mounting assembly is further improved.

[0061] Optionally, in some embodiments, the bending portion 701 is provided with a third through hole corresponding to the first through hole, and the suspension 40 passes through the third through hole, the first through hole and the second through hole in sequence and is connected to the target connection portion 101.

[0062] The third through hole is the same size as the first through hole and is coaxially arranged. By pre-reserving the third through hole on the bending part 701, the suspension 40 can pass through the bending part 701, extend into the target connection part 101, and connect with the target connection part 101.

[0063] Optionally, in some embodiments, the bent portion 701 is also fitted and connected to the first end of the lower crossbeam 20 of the water tank.

[0064] In this embodiment, the bent portion 701 is also fitted and connected to the first end of the lower crossbeam 20 of the water tank. Since the lower crossbeam 20 of the water tank is also a square tubular structure, such as... Figure 3 As shown, the side wall of the lower crossbeam 20 of the water tank fits into and is connected to the bend 701.

[0065] In this embodiment, the first end of the second connecting plate 70 is connected to the first column 30 and the target connecting part 101, and the bent part 701 formed at the second end of the second connecting plate 70 is connected to the target connecting part 101 and the lower crossbeam 20 of the water tank. Through this arrangement, the target connecting part 101, the lower crossbeam 20 of the water tank, and the first column 30 are further fixed together by the second connecting plate 70, improving the connection stability of the suspension mounting assembly.

[0066] This invention also provides an engine compartment, including a second finger beam 80, a water tank upper crossbeam 90, and the aforementioned suspension mounting assembly. The second finger beam 80 is connected to the water tank upper crossbeam 90, and at least one of the second finger beam 80 and the water tank upper crossbeam 90 is connected to the second end of the first column 30.

[0067] In some embodiments, the first finger beam 10 may also be referred to as the upper finger beam or the lower front finger beam, and the second finger beam 80 may also be referred to as the lower finger beam or the upper front finger beam. The middle part of the first finger beam 10 protrudes toward the second finger beam 80 and is fitted to the middle part of the second finger beam 80.

[0068] In some embodiments, the engine compartment has a symmetrical structure, with two symmetrical mounting points. For example... Figure 4 As shown, there are two of each of the first finger beam 10, the second finger beam 80, the first column 30, and the suspension 40. The two ends of the upper crossbeam 90 of the water tank are connected to the two second finger beams 80 respectively, and the two ends of the lower crossbeam 20 of the water tank are connected to the two first finger beams 10 respectively. The two first columns 30 can be referred to as the front column and the rear column respectively.

[0069] The first end of the lower crossbeam 20 of the water tank, together with one of the first finger beams 10 and the front column, forms the first suspension mounting point. The second end of the lower crossbeam 20 of the water tank, together with the other first finger beam 10 and the rear column, forms the second suspension mounting point. The structures at the two symmetrical suspension mounting points are identical, and will not be described in detail here to avoid repetition.

[0070] In the embodiments of this application, such as Figure 4 As shown, the two first finger beams 10, the two second finger beams 80, the upper crossbeam 90 of the water tank, and the lower crossbeam 20 of the water tank form a ring shape, which reduces the number of parts in the engine compartment, lowers the weight of the engine compartment, and increases the space in the engine compartment.

[0071] This invention provides an engine compartment including the aforementioned suspension mounting assembly. This suspension mounting assembly is the same as the one described in the above embodiments, and its specific structure can be found in the descriptions above, which will not be repeated here. Since this embodiment uses the suspension mounting assembly described in the above embodiments, the engine compartment provided in this embodiment has all the beneficial effects of the suspension mounting assembly described in the above embodiments.

[0072] This invention also provides a vehicle that includes the engine compartment described above. This engine compartment is the same as the one described in the above embodiments, and its specific structure can be referred to the description in the above embodiments, which will not be repeated here. Since this embodiment uses the engine compartment from the above embodiments, the vehicle provided in this embodiment has all the beneficial effects of the engine compartment described in the above embodiments.

[0073] For ease of understanding, a specific embodiment will be used as an example below. Please refer to... Figures 1-4 .like Figure 1 As shown, with Figure 1 Taking the suspension mounting point marked in the diagram as an example, this suspension mounting point is located at the first end of the first finger beam 10, and the first end of the first finger beam 10 is provided with a target connection part 101. The second end of the first column 30 overlaps with the second finger beam 80 and the upper crossbeam 90 of the water tank to ensure the Z-direction stiffness of the suspension mounting point. The front end of the suspension mounting assembly is also provided with a first connecting plate 60, which is used to connect the first column 30, the first finger beam 10 and the lower crossbeam 20 of the water tank. The rear end of the suspension mounting assembly is also provided with a second connecting plate 70, which is used to connect the first column 30, the first finger beam 10 and the lower crossbeam 20 of the water tank to increase the installation strength and X-direction stiffness of the suspension mounting point. The target connection part 101 is connected to the lower crossbeam 20 of the water tank, and its tubular structure increases the X-direction stiffness of the suspension mounting point.

[0074] The first finger beam 10 has an internal mounting sleeve 50 that penetrates the first finger beam 10. Both the upper and lower ends of the mounting sleeve 50 are welded to the inner wall of the through hole of the first finger beam 10, increasing the Z-axis stiffness of the suspension mounting point. The mounting sleeve 50 also has internal threads that connect to the suspension bolt 402 for fixing the suspension body 401.

[0075] like Figure 4 As shown, the engine compartment is a ring-shaped structure composed of a first finger beam 10, a second finger beam 80, an upper crossbeam 90 for the radiator, and a lower crossbeam 20 for the radiator. The second ends of the first finger beam 10 and the second finger beam 80 overlap with the A-pillar reinforcement plate. This engine compartment structure replaces the traditional wheel arch structure with a finger beam structure, reducing the number of parts and lowering costs and weight. The ring-shaped structure composed of the first finger beam 10, the second finger beam 80, the upper crossbeam 90 for the radiator, and the lower crossbeam 20 for the radiator reduces the number of engine compartment parts while increasing engine compartment space, resulting in significant cost and weight reduction. The suspension mounting points are directly installed on the tubular parts of the first finger beam 10. Because this part is a single unit, there are no breaks or joints in the force transmission process, resulting in smoother force transmission. The tubular structure design of the first finger beam 10, the first pillar 30, and the lower crossbeam 20 for the radiator increases the X / Y / Z installation rigidity of the suspension mounting points in three-dimensional space.

[0076] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
