Description

Technical Field

[0001] This utility model relates to automotive parts, and more particularly to an inner plate of an offset collision energy absorption box for automobiles. Background Technology

[0002] With the continuous improvement of passive safety performance in automobiles, energy-absorbing boxes, as key energy-absorbing components, are widely used in various vehicles. Energy-absorbing boxes are typically made of lightweight, high-strength metal materials and contain multiple ribs to guide controlled deformation during a collision, thereby dispersing energy and protecting occupants. During the manufacturing process, specific areas of the ribs and box structure are punched using stamping dies to create pre-defined induced deformation zones, ensuring that the energy-absorbing box can effectively absorb energy according to its designed folding pattern during a collision.

[0003] Therefore, the deformation resistance and compressive strength of the inner panels of the offset collision energy-absorbing box are important technical aspects in the manufacturing process of the inner panels of the automotive offset collision energy-absorbing box. Utility Model Content

[0004] The purpose of this utility model is to provide an inner plate component for an offset collision energy absorption box in automobiles, which solves the problem of improving the deformation resistance and pressure resistance performance of the inner plate component for offset collision energy absorption boxes in automobiles.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an inner panel of an offset collision energy-absorbing box for automobiles, including an inner panel body structure, wherein the inner panel body structure is groove-shaped; a group of fixing holes is provided in the inner panel body structure; multiple sets of energy-absorbing inner pressure-reducing wave groove structures are provided in the inner panel body structure and are stamped together with the inner panel body; a stamped inner arc surface is provided at the folded edge of the inner panel body structure; the energy-absorbing inner pressure-reducing wave groove structure includes a bottom wave groove provided in the inner panel body structure and a set of transition flared structures provided at the outer end of each bottom wave groove and connected to the folded edge of the inner panel body structure.

[0006] The fixing hole group includes front and rear fixing holes and positioning column mounting holes.

[0007] The aforementioned transition flare structure includes an extended upper protrusion edge that connects to the upper side of the inner plate body structure of the energy-absorbing box, and an inner end groove edge that connects to the inner side of the inner plate body structure of the energy-absorbing box.

[0008] The energy-absorbing inner pressure wave groove structure is configured in three groups within the energy-absorbing box plate body structure.

[0009] The beneficial effects of this utility model are as follows: The inner plate of the offset collision energy absorption box with the inner pressure wave groove structure effectively ensures that the upper part of the car pillar reinforcement structure has sufficient strength, which can reduce the deformation caused by side collisions and ensure the survival space of the occupants; at the same time, it also ensures that the lower part of the car pillar reinforcement structure has sufficient plastic deformation capacity and appropriate strength, which can absorb the energy generated by side collisions and avoid sheet metal tearing.

[0017] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1, as Figure 1-5 As shown, an inner panel of an offset collision energy-absorbing box for automobiles includes an inner panel body structure 1, which is groove-shaped. A set of fixing holes is provided in the inner panel body structure. Multiple sets of energy-absorbing inner pressure-reducing groove structures, stamped together with the inner panel body, are provided in the inner panel body structure. Three sets of these energy-absorbing inner pressure-reducing groove structures are provided in the inner panel body structure. A stamped inner arc surface 2 is provided at the folded edge of the inner panel body structure. The energy-absorbing inner pressure-reducing groove structure includes a bottom groove 3 provided in the inner panel body structure and a set of transition flared structures connected to the bent edge of the inner panel body structure at the outer end of each bottom groove.

[0020] The aforementioned transition flare structure includes an end-extending protruding edge 4 connected to the upper side of the inner plate body structure of the energy-absorbing box, and an inner end groove edge 5 connected to the inner side of the inner plate body structure of the energy-absorbing box.

[0021] The fixing hole group includes a front fixing hole 6, a rear fixing hole 7, and a positioning post mounting hole 8.

[0022] After the energy-absorbing box is installed onto the main body, the distance between the two energy-absorbing boxes, the weld height, the nuts, and the machining hole positions need to be checked to prevent them from not being installed properly during assembly.

[0023] The inner panel of the offset collision energy absorption box effectively ensures that the upper part of the car pillar reinforcement structure has sufficient strength to reduce deformation caused by side collisions and ensure the survival space of the occupants; at the same time, it also ensures that the lower part of the car pillar reinforcement structure has sufficient plastic deformation capacity and appropriate strength to absorb the energy generated by side collisions and avoid sheet metal tearing.
