Description

Technical Field

[0001] This utility model relates to the field of automotive side panel technology, specifically to a highly formable aluminum alloy side panel structure for new energy vehicles. Background Technology

[0002] The side panels of a car are the outer coverings installed on the left and right sides of the vehicle body, from above the wheel arches to the lower edge of the door. As an important part of the vehicle body frame, they can be connected with other structural components of the vehicle body (such as the roof, floor, and front and rear longitudinal beams) to jointly support the overall rigidity of the vehicle body. In the event of a side collision, they can effectively disperse and absorb the impact force, reduce the deformation of the vehicle body, and provide a safe protection space for the occupants. Highly formable aluminum alloy side panels for new energy vehicles are key components in vehicle lightweighting technology. Compared with traditional side panels, they can reduce weight by up to 30%-40%, directly improving the vehicle's range. After being integrally formed by high-pressure die casting, these side panels are not only lightweight and cost-controllable, but also have excellent energy absorption capacity and corrosion resistance, effectively protecting the safety of occupants in a collision. However, while high-pressure die casting technology endows the side panel with excellent rigidity and protection, making it a reliable support for the vehicle body, its high-strength and highly continuous overall structure also means that in a serious collision, local forces can easily be transmitted to the entire component, creating a "one-size-fits-all" mechanical characteristic. This makes it difficult for rescue and demolition tools to find weak points, ultimately becoming a rescue obstacle that is difficult to cut and demolish quickly. Therefore, to address the above problems, a high-formability aluminum alloy side panel structure based on new energy vehicles is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a highly formable aluminum alloy side panel structure for new energy vehicles, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Based on the high formability aluminum alloy side panel structure of new energy vehicles, the present invention includes a side panel assembly. A pre-drilled hole is provided on the inner side of the side panel assembly. A positioning component is installed inside the pre-drilled hole.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: Based on the high formability aluminum alloy side panel structure of new energy vehicles, it includes a side panel assembly 1. A reserved hole 2 is opened on the inner side of the side panel assembly 1. A positioning component 3 is installed on the inner side of the reserved hole 2. A demolition tool 4 is installed on the outer side of the positioning component 3. The positioning component 3 includes a positioning plate 31. A positioning rod 32 is welded to the outer side of the positioning plate 31. A perforated column 33 is fixedly connected through the inner side of the positioning plate 31. A threaded hole 34 is opened on the inner side of the perforated column 33. A rubber buffer ring 35 is sleeved on the outer side of the perforated column 33. The demolition tool 4 includes a hollow tube 41. A baffle 42 is fixedly connected to the inner side of the hollow tube 41. A bolt 43 is inserted into the inner side of the baffle 42. A retaining ring 44 is fixedly connected to the inner side of the hollow tube 41. A bladed steel claw 45 is welded to the outer side of the hollow tube 41. A protective plug 46 is embedded at one end of the hollow tube 41.

[0017] As a further implementation of this solution, the reserved hole 2 is elliptical in shape, the positioning plate 31 is also elliptical in shape, and the positioning rod 32 is fixed to the side assembly 1 by rivets. The major axis of the reserved hole 2 is aligned with the main load direction of the side assembly 1, which has better resistance to deformation compared to ordinary round holes. At the same time, the positioning plate 31 supports the side assembly 1 through the positioning rod 32, which also ensures that the reserved hole 2 will not become a weak link in the overall structure of the side assembly 1.

[0018] As a further implementation of this scheme, the central axis of the perforated column 33 and the central axis of the positioning plate 31 are on the same straight line. The vertical projection of the perforated column 33 is "I" shaped. The vertical cross-section of the rubber buffer ring 35 is elliptical. The length of the hollow tube 41 is the same as the length of the perforated column 33. The inner diameter of the hollow tube 41 is 1.2 times the outer diameter of the perforated column 33. A gap is provided between the inner side of the baffle 42 and the outer side of the bolt 43. The coaxial design of the perforated column 33 and the positioning plate 31 allows the pressure applied by 33 to the positioning plate 31 to be evenly diffused along the positioning plate 31. The shape of 3 can prevent the rubber buffer ring 35 from falling off its outer side, while also limiting the sliding range of the rubber buffer ring 35 on its outer side. When the rubber buffer ring 35 is obstructed, it will deform, thereby playing a buffering role. The relative arrangement of the hollow tube 41 and the perforated column 33 allows the hollow tube 41 to slide better on the outer side of the perforated column 33, avoiding obstruction and damage to both. The design of a gap between the inner side of the baffle 42 and the outer side of the bolt 43 allows the bolt 43 to pass through the baffle 42 better, preventing it from driving the baffle 42 to rotate when it is screwed.

[0019] As a further implementation of this solution, the length of the threaded hole 34 is the same as the length of the perforated post 33, and the angle between the central axis of the bolt 43 and the perforated post 33 is 90°. The threaded hole 34 matches the bolt 43. During the process of accurately screwing the bolt 43 into the threaded hole 34, the design of the 90° angle between the central axis of the bolt 43 and the perforated post 33 can prevent the bolt 43 from axially shifting or tilting during the screwing process. The design that the length of the threaded hole 34 is the same as the length of the perforated post 33 ensures that the bolt 43 will not be axially obstructed by the perforated post 33 during the entire screwing process.

[0020] As a further implementation of this solution, the inner side of the hollow tube 41 is fitted with the outer side of the rubber buffer ring 35, the transverse projection of the retaining ring 44 is annular, and the rubber buffer ring 35 is located on the side of the retaining ring 44 near the baffle 42, with the outer side of the rubber buffer ring 35 fitted with one side of the retaining ring 44. The design of the inner side of the hollow tube 41 being fitted with the outer side of the rubber buffer ring 35 allows the hollow tube 41 to be installed more stably on the perforated column 33, preventing shaking. At the same time, when the rubber buffer ring 35 deforms, the hollow tube 41 can be evenly stressed. The design of the rubber buffer ring 35 being located on the side of the retaining ring 44 near the baffle 42 allows the rubber buffer ring 35 to be axially positioned by the retaining ring 44 first, and then radially wrapped by the hollow tube 41, and automatically compensates for the gap between the hollow tube 41 and the perforated column 33 during volume deformation.

[0021] As a further implementation of this solution, multiple bladed steel claws 45 are provided. These multiple bladed steel claws 45 are evenly and equidistantly distributed in a circular array on the outside of the hollow tube 41. One end of each bladed steel claw 45 abuts against the side assembly 1. The bladed steel claw 45 is arc-shaped. The design of one end of the bladed steel claw 45 abutting against the side assembly 1 and the arc shape of the bladed steel claw 45 are conducive to the bladed steel claw 45 penetrating the side assembly 1 more effectively. It also plays a certain guiding role in breaking through the side assembly 1. Furthermore, the arc-shaped design makes it less prone to breakage and can withstand greater pressure.

[0022] Workflow: After the side panel assembly 1 is installed, multiple positioning rods 32 are fixed to the side panel assembly 1 using rivets, so that the positioning plate 31, which is welded and fixed to the positioning rods 32, is in the reserved hole 2. The shape of the reserved hole 2 is designed so that its long axis is aligned with the main load direction of the side panel assembly 1, which has better resistance to deformation than ordinary round holes. The positioning plate 31 supports the side panel assembly 1 through the positioning rods 32, and also ensures that the opening of the reserved hole 2 will not become a weak link in the overall structure of the side panel assembly 1. At this time, multiple bladed steel claws 45 abut against the side panel assembly 1. The reaction force exerted by the side panel assembly 1 on the bladed steel claws 45 is acted on the retaining ring 44 through the hollow tube 41. The retaining ring 44 compresses the rubber buffer. The ring 35 causes the rubber buffer ring 35 to deform. The shape of the perforated post 33 ensures that the rubber buffer ring 35 will not fall off the perforated post 33, and at the same time, it fills the gap between the hollow tube 41 and the perforated post 33 after deformation, so that the positioning component 3 and the demolition device 4 form a whole. When the side assembly 1 is slightly deformed by impact, the side assembly 1 bends and slightly squeezes the bladed steel claw 45 due to its own curvature design. The force generated is applied to the rubber buffer ring 35 through the hollow tube 41 and the retaining ring 44, which increases the deformation range of the rubber buffer ring 35. While deforming, the rubber buffer ring 35 also plays a buffering role when the positioning component 3 and the demolition device 4 are subjected to force. When the side panel assembly 1 is severely deformed, if it is difficult to forcibly disassemble the side panel assembly 1, the protective plug 46 can be pried out from the hollow tube 41. With the help of tools, the bolt 43 can be turned so that the bolt 43 penetrates into the threaded hole 34 and pushes the baffle 42. The baffle 42 then moves the hollow tube 41 and the bladed steel claw 45 fixed on the outside of the hollow tube 41. When the bladed steel claw 45 applies pressure to the side panel assembly 1, the arc shape of the bladed steel claw 45 helps one end of the bladed steel claw 45 to better penetrate the side panel assembly 1. In the process of breaking the side panel assembly 1, it can guide the local breaking direction of the side panel assembly 1. With the opening of the reserved hole 2, the efficiency and effect of breaking the side panel assembly 1 can be improved, thus forming a breakthrough for rapid rescue.
