Description

Technical Field

[0001] This utility model relates to the field of automotive structural technology, and more specifically, to a side support structure and an automobile using the support structure. Background Technology

[0002] Side panel assembly lifting points are mainly used for lifting and securing automotive side panel components, and are commonly found in automotive side panel assembly lifting fixtures. The lifting points are typically mounted on brackets or support frames, and use limiting structures to hold the front and rear door frames in place, ensuring stability during the lifting process.

[0003] The current development trends of final assembly lifting points are as follows: multi-vehicle compatibility, as commercial vehicle platforms are diversified (such as light trucks, heavy trucks, and new energy vehicles), requiring adjustable lifting point positions; automation adaptation, as high-precision positioning and automated interfaces are required to cooperate with AGV (automated guided vehicle) or robotic arm assembly; and a balance between lightweight and strength, as materials must meet high strength requirements (such as Q345B steel) while reducing weight.

[0004] The existing technology improves the balance between lightweighting and strength by using double support beams on the upper side panel. There is no separate structural reinforcement at the final assembly lifting point. The strength of the final assembly lifting point and the snow pressure at the top are achieved by stacking the thickness of the inner panels. However, this has the disadvantage of increasing the weight significantly. Utility Model Content

[0005] This invention overcomes the shortcomings of existing technologies that rely on stacking the thickness of inner panels to achieve the strength of the final assembly lifting points and the snow pressure on the top. It provides a side support structure and a car using the support structure, in order to solve the above problems.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this utility model provides a side support structure, including an upper outer side panel, a front outer side panel, an upper side beam reinforcing plate, and a front upper inner side beam.

[0008] The upper outer panel and the front outer panel of the side wall are connected to form the outer surface of the side wall assembly;

[0009] The front outer panel of the side wall and the front upper inner side beam of the side wall are connected. The front upper inner side beam of the side wall forms the inner surface of the side wall assembly and connects the inner panel of the A pillar and the inner panel of the B pillar. A cavity is formed between the front outer panel of the side wall and the front upper inner side beam of the side wall.

[0010] The side panel upper edge beam reinforcing plate is set in the cavity formed between the front outer plate of the side panel and the front upper inner edge beam of the side panel, dividing the cavity into an inner cavity and an outer cavity.

[0011] This utility model achieves localized reinforcement by adding reinforcing plates to the upper side beam. Specifically, this utility model divides the upper side beam cavity into two parts, with the two cavities reinforcing the local strength of the upper side beam, thus providing a new structural form for areas with high structural strength.

[0012] A further technical solution is that the side wall upper beam reinforcing plate, the side wall front outer plate, and the side wall front upper inner beam are connected at the bottom and side to form a three-layer fixed structure;

[0013] The upper side beam reinforcement plate and the upper inner side beam of the side wall are connected at the top to form a double-layer fixed structure.

[0014] A further technical solution is that the three-layer fixing structure is a three-layer spot-welded structure, and the two-layer fixing structure is a two-layer spot-welded structure.

[0015] By using spot welding to connect parts, the strength of the joint is guaranteed, while the structure of the parts is relatively simple and the manufacturing cost is reduced.

[0016] A further technical solution is to provide a side support beam between the side beam and the roof beam of the side assembly;

[0017] The number of side support beams is 1.

[0018] The existing technology uses double support beams on the upper part of the side wall, which can achieve the effect of reinforcement, but also increases the overall weight. This application improves the support performance through structural improvements, which can reduce the number of side wall support beams without affecting performance.

[0019] The side support beams connect the side crossbeams and the top cover crossbeams, forming an overall frame structure.

[0020] A further technical solution is that the side support structure also includes a side upper beam connecting plate, which connects the side upper beam reinforcing plate and the side support beam.

[0021] The upper side beam connecting plate connects the upper side beam reinforcing plate and the side support beam, and plays a role in strengthening and force transmission at the final assembly lifting point.

[0022] In another aspect, this utility model also provides an automobile.

[0023] An automobile includes a side support structure as described above.

[0024] Compared with existing technologies, this utility model has at least the following beneficial effects: This utility model adopts a single side support beam with locally added connecting parts, achieving localized reinforcement through structural means. Specifically, this solution divides the upper side beam cavity in two by adding a reinforcing plate, ensuring joint strength while maintaining a complete and effective force transmission path. This provides a new structural form for areas with high structural strength, solving the problem of increasing strength by stacking inner plate thickness in existing technologies.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0031] Example 1

[0032] A side support structure, see Figures 1-4 It includes: side upper outer panel 1, side front outer panel 2, side upper edge beam reinforcing plate 3, side front upper inner edge beam 4;

[0033] The upper outer panel 1 and the front outer panel 2 of the side wall are connected to form the outer surface of the side wall assembly;

[0034] The front outer panel 2 of the side wall and the front upper inner side beam 4 of the side wall are connected. The front upper inner side beam 4 of the side wall forms the inner surface of the side wall assembly and connects the inner panel of the A pillar and the inner panel of the B pillar. A cavity is formed between the front outer panel 2 of the side wall and the front upper inner side beam 4 of the side wall.

[0035] The side panel upper beam reinforcing plate 3 is disposed in the cavity formed between the side panel front outer plate 2 and the side panel front upper inner beam 4, dividing the cavity into an inner cavity and an outer cavity.

[0036] It is understandable that as long as the side panel upper beam reinforcing plate 3 can separate two cavities within the cavity formed between the side panel front outer plate 2 and the side panel front upper inner beam 4, the strength of the cavity portion can be improved. Therefore, the connection position between the side panel upper beam reinforcing plate 3 and the side panel front outer plate 2 and the side panel front upper inner beam 4 can be set according to requirements.

[0037] In this embodiment, the side upper beam reinforcing plate 3, the side front outer plate 2, and the side front upper inner beam 4 are connected at the bottom and side to form a three-layer fixed structure;

[0038] The upper side beam reinforcement plate 3 and the upper inner side beam 4 of the side wall are connected at the top to form a double-layer fixed structure.

[0039] For example, the side upper beam reinforcing plate 3 has dimensions of 263 mm × 155 mm. The inner cavity formed by the partition has dimensions of 189 mm × 25 mm, and the outer cavity has dimensions of 222 mm × 64 mm. The dual cavities serve to strengthen the local strength of the side upper beam. In this case, CAE verification analysis shows that while meeting the requirements of the final assembly lifting point and top snow pressure, the weight is reduced by 1 kg.

[0040] The final assembly lifting point 9 is located at the upper right corner of the doorway in the driver's cab (when viewed from the left), with a lifting width of 200mm;

[0041] In a further preferred embodiment, a side support beam 7 is provided between the side beam 5 and the top cover beam 6 of the side assembly;

[0042] The number of the side support beams 7 is 1.

[0043] The side support structure also includes a side upper beam connecting plate 8, which connects the side upper beam reinforcing plate 3 and the side support beam 7.

[0044] In this embodiment, the side support beam 7 is changed from two force transmission paths to one, making the structure simpler and more effective. Furthermore, the strength is not reduced even when the upper side beam reinforcement plate 3 is added and the upper side beam cavity is divided into two.

[0046] An automobile includes a side support structure as described above. How this side support structure is installed in the automobile is not the focus of this invention; those skilled in the art can install the side support structure in the automobile in any manner, and will not be elaborated upon herein.

[0047] Although the present invention has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and improvements can be made to the components and / or layout of the subject matter combination within the scope of the present application. Besides variations and improvements to the components and / or layout, other uses will be apparent to those skilled in the art.
