Description

Elbow support structure and vehicle

[0001] Cross-reference to related applications

[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202411737234.4, filed on November 28, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of vehicle structure technology, and more particularly to an elbow support structure and a vehicle. Background Technology

[0004] In the design of vehicle door structure, the elbow support structure needs to take into account two aspects. On the one hand, the elbow support structure needs to have a certain strength to ensure that it will not easily deform and cause poor appearance quality. On the other hand, it needs to be able to absorb the impact force of the outside world in the event of a side collision in order to protect the occupants.

[0005] The elbow rest structure on existing vehicles has no or only a side impact energy-absorbing weakening structure in the collision zone. It has high overall strength but limited crumple distance. The crumple zone has no energy-absorbing or cavity structure, so it cannot absorb the amount of compression on the torso during a collision. It causes greater compression on the occupant's chest and abdomen, resulting in limited protection for the occupant during a collision. In addition, the slot width of the weakening structure is large, and the surface of the product is prone to dents at the slot, resulting in poor appearance quality. Summary of the Invention

[0026] In some embodiments, a sidewall connecting rib is provided in the sidewall weakening hole. The length direction of the elongated sidewall weakening hole is parallel to a third direction, and the third direction is set at an angle to the first direction.

[0039] The technical solution of this disclosure will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] As shown in Figures 1-5, this disclosure provides an elbow support structure, which includes an inner wall plate 1. The inner wall plate 1 is provided with inner wall weakening holes 11 and a first weakening groove 12. The inner wall weakening holes 11 are elongated and there are multiple holes. The multiple inner wall weakening holes 11 are parallel to each other and are arranged at intervals. The first weakening groove 12 is elongated and is connected to the multiple inner wall weakening holes 11 in sequence.

[0041] In this disclosure, the inner wall panel 1 is provided with inner wall weakening holes 11 and first weakening grooves 12. Multiple inner wall weakening holes 11 are provided, which are parallel to each other and arranged alternately. This can effectively reduce the width of a single inner wall weakening hole 11, thereby avoiding the problem of low local strength and easy deformation of the inner wall panel 1, ensuring the product appearance and daily support performance. The first weakening grooves 12 are connected to multiple inner wall weakening holes 11 in sequence, which can form a stress concentration area. During a collision, it can provide large deformation or even fracture, interrupt the force transmission path, and achieve efficient side impact energy absorption and collapse. The inner wall weakening holes 11 and the first weakening grooves 12 work together to take into account both side impact energy absorption and collapse, as well as the product appearance and daily support performance.

[0042] In this embodiment, the inner wall weakening hole 11 penetrates the inner wall plate 1 along the thickness direction, and the first weakening groove 12 is recessed on the inner wall plate 1 along the thickness direction.

[0043] Specifically, the elongated inner wall weakening holes 11 are parallel to the first direction in length. One end of the inner wall plate 1 in the second direction is the top wall connection end. Multiple inner wall weakening holes 11 are arranged at intervals along the direction away from the top wall connection end, with the second direction and the first direction forming an angle. The above arrangement ensures that the inner wall plate 1 can reliably support the top wall connection end.

[0044] More specifically, the inner wall weakening holes 11 include two types: first inner wall weakening holes 111 and second inner wall weakening holes 112. When multiple first inner wall weakening holes 111 are provided, at least one second inner wall weakening hole 112 is sandwiched between two adjacent first inner wall weakening holes 111. When multiple second inner wall weakening holes 112 are provided, at least one first inner wall weakening hole 111 is sandwiched between two adjacent second inner wall weakening holes 112. In the first direction, the size of the second inner wall weakening hole 112 is larger than the size of the adjacent first inner wall weakening hole 111. This configuration can provide greater deformation or even fracture upon collision, interrupting the force transmission path and achieving efficient side-impact energy absorption and crumpling.

[0045] Specifically, along the direction away from the top wall connection end, the lengths of the multiple first inner wall weakening holes 111 decrease sequentially. This arrangement ensures the reliability of the inner wall plate 1's support.

[0046] More specifically, along the direction away from the top wall connection end, the lengths of the multiple second inner wall weakening holes 112 decrease sequentially. This arrangement ensures the reliability of the inner wall plate 1's support.

[0047] In this embodiment, multiple first inner wall weakening holes 111 and second inner wall weakening holes 112 are provided. One or two first inner wall weakening holes 111 are sandwiched between two adjacent second inner wall weakening holes 112. The second direction is perpendicular to the first direction. There are two types of inner wall weakening holes 11. The two types of inner wall weakening holes 11 are the first inner wall weakening hole 111 and the second inner wall weakening hole 112, respectively. The second inner wall weakening hole 112 extends to one end of the inner wall plate 1 in the first direction.

[0048] In other embodiments, the inner wall weakening hole 11 may be provided with one or more types. In other embodiments, the included angle between the second direction and the first direction may also be any other angle, such as 30°, 45° or 60°.

[0049] Specifically, two first weakening grooves 12 are provided, and the distance between the two first weakening grooves 12 gradually decreases along the direction away from the top wall connection end. The above arrangement, while ensuring the daily support performance of the inner wall weakening holes 11, enables the inner wall plate 1 to efficiently collapse and absorb energy.

[0050] More specifically, the inner wall panel 1 also includes a second weakening groove 13, and a plurality of inner wall weakening holes 11 are located on the side of the second weakening groove 13 away from the top wall connection end. The above arrangement ensures that the inner wall panel 1 can collapse toward the top wall connection end.

[0051] In this embodiment, the second weakening groove 13 extends along the first direction and is spaced apart from the adjacent inner wall weakening hole 11. The two ends of the second weakening groove 13 abut against the two first weakening grooves 12 respectively.

[0052] In other embodiments, the first weakening groove 12 may be provided with one or more. In other embodiments, the second weakening groove 13 may be provided with multiple.

[0053] Specifically, the thickness of the inner wall panel 1 at the location of the first weakening groove 12 ranges from 0.8mm to 1.5mm. This design facilitates the formation of stress concentration zones, ensuring the effectiveness of collapse and energy absorption.

[0054] The initial thickness of the inner wall panel 1 is 2.5 mm. In the first embodiment, the thickness at the location of the first weakening groove 12 on the inner wall panel 1 is 0.8 mm, thereby maximizing the structural strength of the inner wall panel 1 and preventing deformation under stress during daily use. In the second embodiment, the thickness at the location of the first weakening groove 12 on the inner wall panel 1 is 1.5 mm, thereby maximizing the ability of the inner wall panel 1 to collapse efficiently upon impact, thus protecting the occupants. In the third embodiment, the thickness at the location of the first weakening groove 12 on the inner wall panel 1 is 1.1 mm, reliably protecting the occupants while preventing deformation under stress during daily use.

[0055] Specifically, the width of the inner wall weakening hole 11 ranges from 1mm to 5mm. Compared with the existing design, reducing the width of the inner wall weakening hole 11 avoids the problem of excessively low local strength of the inner wall plate 1, which can easily lead to deformation, thus ensuring the product's appearance and daily support performance.

[0056] In the first embodiment, the width of the inner wall weakening hole 11 is 1 mm, which can accommodate a thinner and softer outer coating layer and prevent the outer coating layer from sinking into the inner wall weakening hole 11, thus avoiding unevenness on the surface of the outer coating layer. In the second embodiment, the width of the inner wall weakening hole 11 is 5 mm, which can accommodate a thicker and harder outer coating layer. In the third embodiment, the width of the inner wall weakening hole 11 is 3 mm, which can accommodate an outer coating layer of moderate thickness and moderate hardness.

[0057] Specifically, the thickness of the inner wall plate 1 at the location where the second weakening groove 13 is formed ranges from 0.8mm to 1.5mm.

[0058] The initial thickness of the inner wall panel 1 is 2.5 mm. In the first embodiment, the thickness at the location of the second weakening groove 13 on the inner wall panel 1 is 0.8 mm, thereby maximizing the structural strength of the inner wall panel 1 and preventing deformation under stress during daily use. In the second embodiment, the thickness at the location of the second weakening groove 13 on the inner wall panel 1 is 1.5 mm, thereby maximizing the ability of the inner wall panel 1 to collapse efficiently upon impact, thus protecting the occupants. In the third embodiment, the thickness at the location of the second weakening groove 13 on the inner wall panel 1 is 1.1 mm, reliably protecting the occupants while preventing deformation under stress during daily use.

[0059] Specifically, the elbow support structure also includes a top wall plate 2, which is connected to the top wall connection end. The top wall plate 2 is provided with a top wall weakening hole 21, which is elongated. The above configuration enables the top wall plate 2 to effectively collapse and absorb energy.

[0060] More specifically, a top wall connecting rib 22 is provided in the top wall weakening hole 21. The above arrangement avoids the deformation of the top wall plate 2 under pressure during daily use.

[0061] In this embodiment, multiple top wall weakening holes 21 are provided, and the multiple top wall weakening holes 21 are arranged at intervals in sequence. Each top wall weakening hole 21 is provided with at least one top wall connecting rib 22.

[0062] Specifically, the elbow support structure also includes a side wall plate 3. One end of the inner wall plate 1 in the first direction is a side wall connection end, and the side wall plate 3 is connected to the side wall connection end. The side wall plate 3 is provided with a side wall weakening hole 31, which is elongated. The above configuration enables the side wall plate 3 to effectively collapse and absorb energy.

[0063] More specifically, the elongated sidewall weakening holes 31 are parallel to the third direction in their length direction, and the third direction forms an angle with the first direction. The sidewall plate 3 is disposed at one end of the inner wall plate 1 in the first direction. Multiple sidewall weakening holes 31 are provided, and they are arranged at intervals along the direction away from the sidewall connection end. The above arrangement further ensures that the sidewall plate 3 can effectively collapse and absorb energy.

[0064] Specifically, a sidewall connecting rib 32 is provided in the sidewall weakening hole 31. The above arrangement avoids the sidewall plate 3 from deforming under pressure during daily use.

[0065] More specifically, the angle between the extension direction of the sidewall connecting rib 32 and the third direction ranges from 30° to 60°. This setting avoids excessive support force of the sidewall connecting rib 32, which could affect the collapse and energy absorption of the sidewall panel 3.

[0066] In the first embodiment, the angle between the extending direction of the side wall connecting rib 32 and the third direction is 30°, which can adapt to the impact direction of external impact force when the elbow structure is installed outward on the door, achieving energy absorption by the collapse of the side wall panel 3 while ensuring the support strength for daily use. In the second embodiment, the angle between the extending direction of the side wall connecting rib 32 and the third direction is 60°, which can adapt to the impact direction of external impact force when the elbow structure is installed inward on the door, achieving energy absorption by the collapse of the side wall panel 3 while ensuring the support strength for daily use. In the third embodiment, the angle between the extending direction of the side wall connecting rib 32 and the third direction is 45°, which can adapt to the impact direction of external impact force when the elbow structure is installed vertically on the door, achieving energy absorption by the collapse of the side wall panel 3 while ensuring the support strength for daily use.

[0067] In this embodiment, the third direction is perpendicular to the first direction. The side wall plate 3 is located at one end of the inner wall plate 1 in the first direction. The top wall plate 2 is connected to one end of the inner wall plate 1 and the side wall plate 3 in the second direction, respectively connected to the inner wall plate 1 and the side wall plate 3. The second inner wall weakening hole 112 extends to the end of the inner wall plate 1 facing the side wall plate 3. The side wall weakening hole 31 extends along the third direction. Each side wall weakening hole 31 is provided with a plurality of side wall connecting ribs 32. The plurality of side wall connecting ribs 32 are parallel to each other and arranged alternately in the side wall weakening hole 31. The top wall weakening hole 21 extends from the inner wall plate 1 toward the side wall plate 3 and is connected to the side wall weakening hole 31 one by one.

[0068] In other embodiments, a single sidewall weakening hole 31 may be provided. In other embodiments, the included angle between the third direction and the first direction may be any other angle, such as 30°, 45°, or 60°.

[0069] In the elbow support structure disclosed herein, the inner wall panel 1, the top wall panel 2, and the side wall panel 3 are interconnected, and the three are smoothly connected at the corner joint. A corner groove is provided at the corner joint of the inner wall panel 1 and the top wall panel 2, and the extension direction of the corner groove is perpendicular to the first direction. The second inner wall weakening hole 112 extends to the corner joint of the inner wall panel 1 and the side wall panel 3. The inner wall panel 1 constitutes the collision zone, and the top wall panel 2 and the side wall panel 3 constitute the collapse zone.

[0070] This disclosure also provides a vehicle including a door body with the aforementioned elbow rest structure provided on the door body.

During a collision, it can provide greater deformation or even fracture, interrupting the force transmission path and achieving efficient side impact energy absorption and crumple. The inner wall weakening holes 11 and the first weakening grooves 12 work together to take into account both side impact energy absorption and crumple, as well as product appearance and daily support performance.
