Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to an engine mount support plate, an engine mount support structure, and a vehicle. Background Technology

[0002] The engine mount support plate is a core load-bearing component of the automotive powertrain mounting system. It provides a reliable welding reference for the mount nut tube, ensuring a stable connection between the mount nut tube and the longitudinal beam. Currently, most mainstream engine mount support plates adopt a semi-open U-shaped structure design. However, the torsional stiffness of its U-shaped cross-section is relatively weak, and the sidewalls are almost perpendicular to the top and bottom surfaces. This can easily lead to stress concentration at the top and root of the sidewalls, affecting the connection stability of the mount assembly. Utility Model Content

[0011] Optionally, the vehicle body longitudinal beam includes an inner side plate with a Z-shaped cross-section. A longitudinal beam reinforcing plate is attached to the inner side of the inner side plate. The longitudinal beam reinforcing plate has a U-shaped cross-section. The inner side of the bottom plate of the longitudinal beam reinforcing plate is connected to the main body of the engine mount support plate. The mount nut tube is connected to the top surface of the mounting boss of the engine mount support plate, and its top end is connected to the top side wall of the longitudinal beam reinforcing plate. A first through hole is provided on the top side wall of the longitudinal beam reinforcing plate and the top side wall of the inner side plate, opposite to the top end of the mount nut tube, to form a first mount mounting hole.

[0012] Optionally, the top sidewall of the longitudinal beam reinforcing plate and the top sidewall of the inner side plate are both provided with a second through hole to form a second suspension mounting hole; the top sidewall between the second suspension mounting hole and the first suspension mounting hole is recessed to form a first clearance groove; the two ends of the plate body along the length direction of the vehicle body longitudinal beam are respectively located on both sides of the first suspension mounting hole, and the end closer to the second suspension mounting hole is located in the middle of the first clearance groove.

[0022] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Although some embodiments of this utility model are shown in the drawings, it should be understood that this utility model can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this utility model. It should be understood that the drawings and embodiments of this utility model are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0023] The term "comprising" and its variations as used herein are open-ended, meaning "including but not limited to"; the term "based on" means "at least partially based on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; and the term "optionally" means "optional embodiments". Definitions of other terms will be given in the following description. It should be noted that the concepts of "first," "second," etc., mentioned in this utility model are only used to distinguish different devices, modules, or units, and are not used to limit the order of functions performed by these devices, modules, or units or their interdependencies.

[0024] It should be noted that the terms "one" and "multiple" used in this utility model are illustrative rather than restrictive. Those skilled in the art should understand that, unless explicitly stated otherwise in the context, they should be understood as "one or more". "Several" refers to one or more "one or more".

[0025] like Figure 1 and Figure 2 As shown, this utility model embodiment provides an engine mount support plate, including a plate body 1 for connecting with the vehicle body longitudinal beam 2. A portion of the plate body 1 protrudes to one side to form a mounting boss 11. The mounting boss 11 is frustoconical in shape, and the top surface of the mounting boss 11 is used to connect with the mount nut tube 3. Figure 1 and Figure 2 The mounting structure of the engine mount support plate is shown when it is used as the left front mount support plate.

[0026] In this embodiment, the engine mount support plate includes a plate body 1, which has a frustum-shaped mounting boss 11 formed by a local material protrusion. The top surface of the mounting boss 11 serves as the welding bearing reference for the mount nut tube 3, ensuring accurate welding position and reliable connection. The sidewalls of the mounting boss 11 surround its top surface, forming a continuous closed-loop support structure. Compared with the conventional zigzag semi-open structure, this effectively avoids the problem of weak torsional resistance caused by structural hollowing, resulting in higher overall torsional stiffness. At the same time, the mounting boss 11 is frustum-shaped, meaning its annular sidewalls are arranged obliquely on the plate body 1, which can significantly reduce stress concentration at the top and root connection points of the sidewalls, further ensuring the connection stability of the mount assembly during long-term use.

[0027] In addition, the mounting boss 11 is frustum-shaped (including truncated pyramids, truncated cones, etc.), exhibiting high local strength and strong resistance to compression and shearing, making it suitable for concentrated load scenarios such as the suspension nut tube 3. For example... Figure 2 As shown, in this embodiment, the mounting boss 11 is specifically a quadrangular frustum.

[0028] It should be noted that the "side" of the aforementioned panel body 1 specifically refers to the side opposite to the mounting surface of the panel body 1 and the vehicle body longitudinal beam 2. That is, the direction of the protrusion of the mounting boss 11 is away from the mounting surface of the vehicle body longitudinal beam 2 and the panel body 1, so as to avoid spatial interference.

[0029] Optionally, such as Figure 2 As shown, multiple parts of the main body 1 protrude to the other side to form multiple connecting bosses 12. The top surfaces of the multiple connecting bosses 12 are used to connect with the vehicle longitudinal beam 2 to realize the connection between the main body 1 and the vehicle longitudinal beam 2.

[0030] In this optional embodiment, multiple local protrusions of the plate body 1 form multiple connecting bosses 12. Through the multiple points of contact between the top surfaces of these connecting bosses 12 and the longitudinal beams 2, the load transmitted from the plate body 1 to the longitudinal beams 2 can be distributed, improving the stability and assembly accuracy of the connection. Furthermore, gap cavities are formed between the plate body 1 and the longitudinal beams 2 at the locations between the connecting bosses 12. These cavities can disperse local stress, preventing stress concentration and thus strengthening the overall structural strength after the connection. The top surfaces of the connecting bosses 12 can be flat planar structures to fit and connect with the corresponding surfaces of the longitudinal beams 2.

[0031] Optionally, such as Figure 2 As shown, at least one connecting boss 12 is provided at the front, rear and bottom of the mounting boss 11.

[0032] In this optional embodiment, to achieve the supporting function of the suspension assembly, the mounting boss 11 is typically arranged at the top edge of the main body 1 in the installation posture. Based on this arrangement, after the main body 1 is connected to the vehicle longitudinal beam 2, at least one connecting boss 12 is provided in front of, behind and below the mounting boss 11, so that the fixed connection points with the vehicle longitudinal beam 2 are reasonably distributed around the mounting boss 11, ultimately ensuring the reliability of the connection.

[0033] Specifically, such as Figure 2 As shown, by combining the dimensions of the main body 1 and the actual structural form of the longitudinal beam 2, multiple connecting bosses 12 can be flexibly set to achieve a stable connection with the longitudinal beam 2 and to form a reverse structural reinforcement for it.

[0034] It should be noted that all directional concepts mentioned in this document, such as front, rear, below, inside, and outside, are based solely on the vehicle's own direction, and are specifically defined as follows: Front: refers to the normal forward direction of the vehicle, corresponding to... Figure 1 , Figure 2 The X direction marked in the middle; below: refers to the direction perpendicular to the ground and pointing towards the bottom, corresponding to... Figure 1 , Figure 2 The negative direction of the Z-axis is marked in the middle; inside: refers to the direction towards the inside of the vehicle body; outside: refers to the direction away from the inside of the vehicle body.

[0035] Optionally, such as Figure 1 and Figure 2 As shown, the edges of the main body 1 are all folded to one side to form a ring-shaped flange structure 13. The flange structure 13 is provided with a notch 130 to avoid the suspension nut tube 3. The flange structure 13 is used to connect with the vehicle body longitudinal beam 2.

[0036] In this optional embodiment, the perimeter of the plate body 1 is folded away from the side of the vehicle body longitudinal beam 2 to form a closed-loop annular flange structure 13; the flange structure 13 has a notch 130 in the area corresponding to the installation position of the suspension nut tube 3 to avoid the installation space of the suspension nut tube 3 and avoid structural interference; at the same time, the flange structure 13 is also used to fit and connect with the corresponding edge of the vehicle body longitudinal beam 2.

[0037] By folding the main body 1 around to form a ring-shaped flange structure 13, the bending and torsional stiffness of the engine mount support plate can be significantly improved, preventing warping and deformation of the edges of the main body 1. The notch 130 avoids the mounting nut tube 3 during installation. Furthermore, during installation, the flange structure 13 is also connected to the vehicle body longitudinal beam 2, for example... Figure 1 and Figure 2 As shown, the main body 1 is connected to the bottom plate inside the U-shaped cavity of the vehicle body longitudinal beam 2. The top and bottom of the flange structure 13 are fitted and connected to the upper and lower side walls of the vehicle body longitudinal beam 2, which can strengthen the connection strength between the two and help strengthen the local structural strength of the corresponding part of the vehicle body longitudinal beam 2.

[0038] Optionally, the edge of the notch 130 is connected to the side wall of the suspension nut tube 3.

[0039] In this optional embodiment, the edge of the notch 130 is fixedly connected to the side wall of the suspension nut tube 3 to form a lateral limit on the suspension nut tube 3. In addition, the top end of the suspension nut tube 3 is usually connected to the vehicle body longitudinal beam 2, so that the suspension nut tube 3 has triple positioning of the top surface of the mounting boss 11, the edge of the notch 130 of the flange structure 13, and the vehicle body longitudinal beam 2, which further improves the installation coaxiality and stability of the suspension nut tube 3.

[0040] Optionally, such as Figure 2 As shown, the top surface of the mounting boss 11 is surrounded by an arc-shaped groove 111, which is used to connect with the side wall of the suspension nut tube 3.

[0041] In this optional embodiment, the top surface of the mounting boss 11 is provided with an arc-shaped groove 111. The inner curvature of the arc-shaped groove 111 can be adapted to the outer curvature of the suspension nut tube 3 for a close and fixed connection with the side wall of the suspension nut tube 3. The arc-shaped groove 111 on the top surface of the mounting boss 11 increases the contact area between the suspension nut tube 3 and the mounting boss 11, improves the connection strength, and can also play a pre-positioning role for the suspension nut tube 3, preventing the nut tube from shifting during assembly and improving installation accuracy. In addition, after the engine mount support plate is fixedly installed, the axis of the arc-shaped groove 111 is collinear with the axis of the suspension nut tube 3 in the vertical direction, ensuring that the two are coaxially assembled.

[0042] Optionally, such as Figure 2 As shown, the engine mount support plate is an integrally molded structure, and the side wall of the mounting boss 11 is provided with a reinforcing structure 112. The side wall of the mounting boss 11 smoothly transitions at the edge line.

[0043] In this optional embodiment, the engine mount support plate can be a sheet metal part, and the reinforcing structure 112 can be a reinforcing rib. The plate body 1, the mounting boss 11, and the reinforcing structure 112 are integrally formed by stamping, without the need for additional splicing or welding, resulting in high production efficiency and low cost. The reinforcing structure 112 of the side wall can directly enhance the moment of inertia of the section of the mounting boss 11, thereby improving its bending and torsional stiffness. All side wall edges of the mounting boss 11 are rounded and smoothly transitioned to avoid stress concentration. Specifically, the edges include the intersection line of adjacent side walls, the connecting edge line between the side wall and the top surface of the mounting boss 11, and the connecting edge line between the side wall and the plate body 1.

[0044] Specifically, the reinforcing structure 112 can be arranged along the height direction of the side wall (i.e., the direction of the protrusion height of the mounting boss 11) or circumferentially. For example... Figure 2 As shown, the mounting boss 11 can be in the shape of a frustum, and the reinforcing structure 112 is arranged circumferentially; because the mounting boss 11 overlaps with the surrounding structure, it is not a complete frustum structure, and the corresponding reinforcing structure 112 is also incomplete; the final sidewall shape of the mounting boss 11 can be as follows. Figure 3 As shown, the sidewall of the mounting boss 11 extends obliquely upward in a wave-like shape. This structure can effectively disperse stress and therefore has higher structural strength.

[0045] It should be noted that, in Figure 2 In the process, due to installation requirements, the top surface of the mounting boss 11 is designed as a stepped surface structure: the higher stepped surface is used to connect the suspension nut tube 3, and the lower stepped surface has positioning holes 113 for positioning during welding connection operations, thereby realizing the integrated design of the structure.

[0046] Optionally, the main body 1 of the plate is in the shape of a rectangular plate.

[0047] In use, first, attach the suspension nut tube 3 to the preset position on the arc groove 111, then weld at the notch 130 and the arc groove 111 to fix the suspension nut tube 3 to the plate body 1; then position the plate body 1 at the installation position of the vehicle body longitudinal beam 2, and then weld the top surface of each connecting boss 12 to the vehicle body longitudinal beam 2 to complete the installation.

[0048] like Figure 1 As shown, another embodiment of this utility model provides an engine mount support structure, including a vehicle body longitudinal beam 2 and a mount nut tube 3, and also includes the aforementioned engine mount support plate. The technical improvements and effects of this engine mount support structure are the same as those of the aforementioned engine mount support plate, and will not be repeated here. Optionally, such as Figure 1 and Figure 4 As shown, the vehicle body longitudinal beam 2 includes an inner side plate 21 with a Z-shaped cross-section. A longitudinal beam reinforcing plate 22 is attached to the inner side of the inner side plate 21. The longitudinal beam reinforcing plate 22 has a U-shaped cross-section. The inner side of the bottom plate 221 of the longitudinal beam reinforcing plate 22 is connected to the plate body 1 of the engine mount support plate. The mount nut tube 3 is connected to the top surface of the mounting boss 11 of the engine mount support plate, and its top end is connected to the top side wall 222 of the longitudinal beam reinforcing plate 22. The top side wall 222 of the longitudinal beam reinforcing plate 22 and the top side wall of the inner side plate 21 are both provided with a first through hole at the part opposite to the top end of the mount nut tube 3 to form a first mount mounting hole 23.

[0049] In this optional embodiment, the vehicle longitudinal beam 2 may include an inner side plate 21 near the inner side of the vehicle body and an outer side plate 25 near the outer side of the vehicle body. The cross-section of the inner side plate 21 is shaped like a "Z", with the opening of the "Z" shape facing the outer side plate 25. The inner side surface of the inner side plate 21 is the surface located inside the "Z" shape. A longitudinal beam reinforcing plate 22 is provided on the inner side surface of the inner side plate 21, which does not affect the appearance of the vehicle longitudinal beam 2, but can improve the structural strength of the vehicle longitudinal beam 2 at the position supporting the powertrain, i.e., the mounting bracket. The plate body 1 is provided on the inner side surface of the longitudinal beam reinforcing plate 22, so that the longitudinal beam reinforcing plate 22, the plate body 1, and the inner side plate 21 together form a three-layer structure, effectively ensuring the overall structural strength. In addition, the opening of the "Z" shaped inner side plate 21 is horizontally facing the outer side of the vehicle body, and the suspension nut tube 3 is arranged vertically.

[0050] Optionally, such as Figure 1 and Figure 4As shown, the top sidewall 222 of the longitudinal beam reinforcing plate 22 and the top sidewall of the inner side plate 21 are both provided with second through holes to form second suspension mounting holes 24; the top sidewall 222 between the second suspension mounting hole 24 and the first suspension mounting hole 23 is recessed to form a first clearance groove 2220; the two ends of the plate body 1 along the length direction of the vehicle longitudinal beam 2 are respectively located on both sides of the first suspension mounting hole 23, and the end closer to the second suspension mounting hole 24 is located in the middle of the first clearance groove 2220.

[0051] In this optional embodiment, by arranging the two ends of the plate body 1 on both sides of the first suspension mounting hole 23, and extending the end near the second suspension mounting hole 24 to the middle of the first clearance groove 2220, the length of the plate body 1 is designed to cover most of the area of ​​the first clearance groove 2220 and the transition area on one side (facing the front of the vehicle), thereby specifically strengthening the weak part of the clearance groove.

[0052] It should be noted that the length direction of the longitudinal beam 2 is the same as the longitudinal direction of the vehicle. The second mount hole 24 is located behind the first mount hole 23, thus providing two mount holes on one longitudinal beam to achieve stable support and connection for the powertrain. The first clearance groove 2220 is recessed downwards to allow space for the powertrain, providing more space for its installation. Another engine mount support plate, as described above, can be installed at the second mount hole 24.

[0053] Optionally, such as Figure 2 and Figure 5 As shown, the flange structure 13 of the engine mount support plate includes a top flange 131, which is stepped and includes a first step plate 1311 and a second step plate 1312. A portion of the first step plate 1311 is fitted and connected to the inner wall of the top sidewall 222 at the first clearance groove 2220, and the first step plate 1311 extends to the side of the first mount mounting hole 23 away from the first clearance groove 2220. A notch 130 for the engine mount support plate is provided on the first step plate 1311 opposite to the first mount mounting hole 23. The inner wall of the top sidewall 222 on the side of the first mount mounting hole 23 away from the first clearance groove 2220 is fitted and connected to the second step plate 1312.

[0054] In this optional embodiment, by designing the top flange 131 as a stepped structure, it can adapt to and fit the inner wall structure of the longitudinal beam reinforcing plate 22 at the first clearance groove 2220; at the same time, by optimizing the length arrangement of the first stepped plate 1311, a gap is formed between the longitudinal beam reinforcing plate 22 and the top flange 131 at the installation position of the suspension nut tube 3. This gap facilitates the welding operation between the top of the suspension nut tube 3 and the longitudinal beam reinforcing plate 22, and also forms a gap cavity, further improving the structural strength.

[0055] It should be noted that, as Figure 5 As shown, the flange structure 13 also includes a bottom flange 132, a front flange 133, and a rear flange 134. The top flange 131, bottom flange 132, front flange 133, and rear flange 134 are respectively arranged at the top edge, bottom edge, front edge, and rear edge of the main body 1, and are connected sequentially to form a ring-shaped flange structure 13. Figure 5 As shown, since the bottom sidewall 223 of the longitudinal beam reinforcing plate 22 protrudes to form a second clearance groove (not shown) at the position corresponding to the first clearance groove 2220, the bottom flange 132 is also stepped; however, since there is no need to arrange the suspension nut tube 3, the bottom flange 132 and the bottom sidewall 223 of the inner side plate 21 are almost completely fitted and connected. In addition, the plate body 1, which is roughly rectangular, has the same width as the inner cavity width of the longitudinal beam reinforcing plate 22, which can ensure that the plate body 1 and the inner cavity of the longitudinal beam reinforcing plate 22 are precisely matched.

[0056] Optionally, such as Figure 4 As shown, the opening of the inner side panel 21 is connected to the outer side panel 25. The outer side panel 25 closes the zigzag opening of the inner side panel 21, forming a closed-section longitudinal beam 2 of the vehicle body.

[0057] Another embodiment of this utility model provides a vehicle including the aforementioned engine mount support structure. The technical improvements and effects of the vehicle are the same as those of the engine mount support structure, and will not be repeated here.

[0058] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
