Description
Technical Field
[0001] This utility model relates to the technical field of automobile door armrests, and in particular to a door armrest assembly, a door, and a vehicle. Background Technology
[0002] People are increasingly concerned about the safety of cars during driving, especially the safety of occupants in high-speed collisions. However, the requirements for interior design to ensure occupant safety often conflict with other attributes. For example, in order to meet the comfort requirements of drivers and passengers, a wider door armrest needs to be designed. In the event of a side collision, the door sheet metal will deform as it intrudes upon impact. A wider door armrest will aggravate the impact injury to the chest or abdomen of the person on the side of the door. At this time, the buffering effect of the side airbag will be reduced, which greatly increases the risk of rib fractures and internal organ damage to the occupant.
[0003] In order to ensure the comfort of occupants' arms and reduce the injury caused by wide door armrests in side collisions, the strength of the armrests can be reduced. Existing methods to reduce the strength of the armrests are to reduce the strength of the armrest materials or to directly weaken them, which makes the modal properties of the door and the strength and support of the armrests worse, and cannot meet the requirements of balancing comfort and safety. Utility Model Content
[0004] To address the technical problem that car door armrests cannot guarantee strength while satisfying comfort, this utility model provides a car door armrest assembly, a car door, and a vehicle.
[0005] To achieve the above objectives, this utility model provides a car door armrest assembly, including an armrest mounting frame and a collapsible portion. The armrest mounting frame includes a first mounting frame, a second mounting frame, and an opening. A first end of the collapsible portion is connected to the first mounting frame, and a second end of the collapsible portion is connected to the second mounting frame. The collapsible portion is obliquely arranged in the horizontal direction.
[0006] Furthermore, the collapsible portion includes a plurality of connecting ribs, the first end of the connecting ribs being connected to the first mounting frame, the second end of the connecting ribs being connected to the second mounting frame, and the first ends and / or the second ends of the plurality of connecting ribs extending in opposite directions.
[0007] Furthermore, the thickness of the connecting rib in the vertical direction is greater than the thickness of the connecting rib in the horizontal direction.
[0008] Furthermore, the handrail mounting frame also includes a connecting part, and the two sides of the first mounting frame and the second mounting frame are connected through the connecting part. The first mounting frame and the second mounting frame are respectively disposed at the upper end and the lower end of the opening, and the projections of the first mounting frame and the second mounting frame in the vertical direction do not overlap.
[0009] Furthermore, the handrail mounting frame also includes a collapsible connector, the bottom of which is a recessed portion that communicates with the opening.
[0010] Furthermore, the collapsible connector extends horizontally into the vehicle, with the end of the collapsible connector away from the vehicle connected to the first mounting frame, and the end of the collapsible connector facing into the vehicle connected to the first end of the collapsible portion.
[0011] Furthermore, the handrail mounting frame also includes a first inner panel mounting part and a second inner panel mounting part. The first inner panel mounting part is disposed on the first mounting frame, and the second inner panel mounting part is disposed on the second mounting frame. The first inner panel mounting part and the second inner panel mounting part are staggered in the horizontal direction.
[0012] Furthermore, the handrail mounting frame also includes a third inner plate mounting part, the two ends of which are respectively connected to the second ends of two adjacent connecting ribs.
[0013] Another objective of this embodiment is to provide a vehicle door that is provided with the aforementioned door armrest assembly.
[0014] Another object of this embodiment is to provide a vehicle that is provided with the above-described door armrest assembly or door.
[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:
[0016] (1) A crumple section is set on the mounting frame with the greatest strength and is set diagonally in the horizontal direction. When the door is hit by a side collision, the crumple section can be squeezed and collapse to absorb the side impact force and buffer the injury to the occupants.
[0017] (2) Since the first mounting frame and the second mounting frame in the handrail assembly do not overlap in the vertical direction, and the crumple section extends downward in the vertical direction, the impacted part can continue to deform and absorb energy after the crumple section breaks.

[0029] Example 1
[0030] Reference Figure 1 and 2 This invention provides a door armrest assembly that effectively improves the safety of the armrest structure while ensuring passenger comfort. Currently, people have increasingly higher demands for high-end passenger vehicles, pursuing aesthetics, comfort, and high durability. To meet these demands, door interiors require wider armrests, multi-layered trim panels, decorative strips, and ambient lighting, among other components. Additionally, harder materials and thicker mounting frames are used to meet requirements for high durability and vibration modal properties. When a car experiences a high-speed side impact, the door sheet metal deforms upon impact, and the inner door panel intrudes into the occupant. Due to inertia, the occupant moves towards the door panel. If the armrest is wide, most of the side airbag's volume will be positioned above the armrest, failing to buffer the passenger's injury. Furthermore, as the vehicle body intrudes, a wider armrest results in greater intrusion into the occupant's chest and abdomen, leading to more severe injuries. This application addresses this by incorporating a weakening structure at the location of the stiffest mounting frame, allowing this part to collapse under lateral pressure during a side impact, thereby reducing injury to the occupant.
[0031] like Figures 1-3As shown in the figure, a car door armrest assembly provided in this embodiment of the present invention includes an armrest mounting frame 1 and a collapsible portion 2. The armrest mounting frame 1 includes a first mounting frame 12, a second mounting frame 13, and an opening 14. The first end of the collapsible portion 2 is connected to the first mounting frame 12, and the second end of the collapsible portion 2 is connected to the second mounting frame 13. The collapsible portion 2 is inclined in the horizontal direction. In this embodiment, the armrest mounting frame 1 is used to mount the armrest structure on the inner panel of the car door. The first mounting frame 12 and the second mounting frame 13 are arranged in the armrest mounting frame 1. On different vertical planes, the second mounting frame 13 is closer to the occupants in the horizontal direction than the first mounting frame 12. The crumple zone 2 is inclined in the horizontal direction. Specifically, the line connecting the two ends of the crumple zone 2 to the first mounting frame 12 and the second mounting frame 13 is not perpendicular to the vehicle's central axis. When the crumple zone 2 is subjected to a horizontal impact, it deforms or even breaks, thereby absorbing the impact force when the door collides. After the crumple zone 2 deforms or breaks, the second mounting frame 13 shifts towards the opening 14, reducing the impact on passengers and improving safety.
[0032] It should be noted that the opening 14 in the handrail mounting frame 1 is set as a long strip, and the opening 14 and the collapse part 2 are set at a height approximately at the chest and abdomen of the occupant, which can better play a safety protection role. Furthermore, in order to ensure a certain support strength, multiple sets of collapse parts 2 are provided.
[0033] In one embodiment, the collapsible portion 2 includes a plurality of connecting ribs 21. The first end of the connecting rib 21 is connected to the first mounting frame 12, and the second end of the connecting rib 21 is connected to the second mounting frame 13. The first ends and / or the second ends of the plurality of connecting ribs 21 extend in opposite directions. In this embodiment, each collapsible portion 2 includes two connecting ribs 21, namely a first connecting rib and a second connecting rib. The first ends of the first connecting rib and the first ends of the second connecting rib are far apart from each other, and the second ends of the first connecting rib and the second ends of the second connecting rib are close to each other. This improves the strength of the collapsible portion 2 in the vertical direction without affecting the deformation of the collapsible portion 2 under stress in the horizontal direction.
[0034] In one embodiment, the thickness of the connecting rib 21 in the vertical direction is greater than the thickness of the connecting rib 21 in the horizontal direction. The thickness of the connecting rib 21 in the vertical direction refers to the straight-line distance between the upper and lower horizontal planes of the connecting rib 21, while the thickness of the connecting rib 21 in the horizontal direction refers to the length of the connection surface between the connecting rib 21 and the handrail mounting frame 1 in the horizontal direction. Since the connecting rib 21 is thicker in the vertical direction, it can improve the strength of the collapsible part 2 in the vertical direction, ensuring a certain support strength and meeting the requirements of vibration mode and support strength properties.
[0035] In one embodiment, refer to Figure 3The contractile portion 2 includes multiple sets of connecting ribs 21. The connecting ribs 21 are divided into multiple groups, each group including at least two connecting ribs 21. Each group of connecting ribs 21 connects to a third inner panel mounting portion 33. Furthermore, the first ends of each group of connecting ribs 21 are close to each other. In the embodiment, the connecting ribs 21 connecting each third inner panel mounting portion 33 are close to each other, and the two connecting ribs 21 are connected to the contractile portion connector 121 to form an approximately triangular structure, which improves the stability of the installation of the third inner panel mounting portion 33 and the strength of the connecting ribs 21 in the vertical direction. As can be seen from the figure, the first end of the connecting rib 21 is the end closer to the vehicle interior. When the contractile portion 2 breaks, that is, when the connecting rib 21 breaks, since the ends of multiple connecting ribs 21 are close to each other and the contractile portion 2 extends downward in the vertical direction, the connecting ribs 21 will not overlap after the contractile portion 2 breaks, thus enabling further energy absorption and deformation.
[0036] In one embodiment, refer to Figure 1 and 2 The handrail mounting frame 1 also includes a connecting part 11. The two sides of the first mounting frame 12 and the second mounting frame 13 are connected by the connecting part 11. The first mounting frame 12 and the second mounting frame 13 are respectively set at the upper end and the lower end of the opening 14. The projections of the first mounting frame 12 and the second mounting frame 13 in the vertical direction do not overlap. In the embodiment, the first mounting frame 12 and the second mounting frame 13 are both set in the vertical direction. The first mounting frame 12 is connected to the upper end of the opening 14, and the second mounting frame 13 is connected to the lower end of the opening 14. The first mounting frame 12 and the second mounting frame 13 do not overlap in the vertical direction. Therefore, when a collision occurs, even if the crumple portion 2 breaks, the first mounting frame 12 and the second mounting frame 13 will be pressured to the same vertical plane. The first mounting frame 12 and the second mounting frame 13 can still continue to move alternately in the horizontal direction to absorb energy and deform.
[0037] It should be noted that the connecting part 11 can be a bent structure. The entire armrest mounting frame 1 is set in the vertical direction. The connecting part 11 can be bent twice. The first bend is inward in the horizontal direction, and then bends downward in the vertical direction to form two bent structures. On the one hand, it can match the shape of the inner panel of the door armrest, and on the other hand, it provides an installation position for the crumple zone. Since the connecting part 11 includes a horizontal part, it will increase the horizontal strength. Setting the opening 14 in the middle of the armrest mounting frame 1 can reduce the horizontal strength of the connecting part 11. The connecting parts 11 are distributed on the left and right sides of the opening 14, which plays a connecting role and facilitates the crumple zone of the middle of the armrest mounting frame 1 when subjected to a lateral impact.
[0038] In one embodiment, refer to Figure 1The first mounting frame 12 includes a collapsible connector 121, which extends horizontally into the vehicle. The bottom of the collapsible connector 121 is a recessed portion, which is connected to the opening 14. This not only expands the size of the opening to absorb deformation, but also provides space for the displacement of the collapsible connector 121 when it is under stress.
[0039] In one embodiment, the collapsible connector 121 extends horizontally into the vehicle. The end of the collapsible connector 121 away from the vehicle is connected to the first mounting frame 12, and the end of the collapsible connector 121 facing into the vehicle is connected to the first end of the collapsible portion 2. In this embodiment, the collapsible connector 121 has a groove structure, consisting of an upper top surface and two opposing side walls. The two opposing side walls of the collapsible connector 121 facing into the vehicle are connected to the collapsible portion 2, ensuring the width of the handrail in the horizontal direction and providing a certain support strength for daily use.
[0040] In one embodiment, refer to Figure 1 and 2 The armrest mounting frame 1 also includes a first inner panel mounting part 31 and a second inner panel mounting part 32. The first inner panel mounting part 31 is disposed on the first mounting frame 12, and the second inner panel mounting part 32 is disposed on the second mounting frame 13. The first inner panel mounting part 31 and the second inner panel mounting part 32 are staggered in the horizontal direction. It should be noted that the first inner panel mounting part 31 extends in the horizontal direction, and an inner panel mounting point is provided on the upper surface of the first inner panel mounting part 31. The second inner panel mounting part 32 is disposed on the side wall of the second mounting frame 13 facing the vehicle interior, and the inner panel mounting point is disposed on the side wall of the second inner panel mounting part 32 facing the vehicle interior. The inner panel mounting point is used to install the inner panel of the door, and the inner panel of the door is used to cover the armrest mounting frame 1.
[0041] In one embodiment, the armrest mounting frame 1 further includes a third inner panel mounting part 33. The two ends of the third inner panel mounting part 33 are respectively connected to the second ends of two adjacent connecting ribs 21. The third inner panel mounting part 33 is connected to the collapsible part connector 121 through the two connecting ribs 21, and then connected to the first inner panel mounting part 31. It can support and fix the connecting ribs 21. It should be noted that the third inner panel mounting part 33 is installed in the horizontal direction. The upper surface of the third inner panel mounting part 33 is also provided with an inner panel mounting point for installing the inner panel of the car door. The third inner panel mounting part 33 is connected to the connecting ribs 21. The inner panel of the car door is subjected to horizontal pressure and the pressure is transmitted to the third inner panel mounting part 33, and further transmitted to the connecting ribs 21, thereby realizing that the connecting ribs 21 are deformed or even broken under pressure, thereby improving the safety effect.
[0042] The working principle of the door armrest assembly provided in this embodiment is as follows: the inner panel of the door is installed on the first inner panel mounting part 31, the second inner panel mounting part 32, and the third inner panel mounting part 33 on the armrest mounting frame 1. The third inner panel mounting part 33 is connected to the collapsible part 2, and the collapsible part 2 is connected to the first mounting frame 12 through the collapsible part connector 121. The connecting part 11 connects the second mounting frame 13 to the first mounting frame 12. During installation, the third inner panel mounting part 33 can be used to install the interior armrest in the inner panel of the door. When the door is hit by a side impact, the impact force will cause the first mounting frame 12 and the second mounting frame 13 to deform horizontally inward. In order to protect the safety of the occupants, an airbag is usually installed at the door. When the mounting frame 12 and the second mounting frame 13 deform inwards, the airbag deploys. The airbag is positioned at the occupant's chest and abdomen. After deployment, the occupant's chest and abdomen react to the first mounting frame 12 and the second mounting frame 13 through the deployed airbag, causing the crumple zone 2 to collapse until it breaks. This absorbs horizontal deformation and prevents the collision from causing significant injury to the occupant. Furthermore, since the projections of the first mounting frame 12 and the second mounting frame 13 in the vertical direction do not overlap, even when the first mounting frame 12 and the second mounting frame 13 are on the same plane in the vertical direction, they can still absorb energy and deform, further improving the occupant's safety. In addition, the inner panel mounting section and the crumple zone 2 in this proposal ensure a certain level of support strength, facilitating daily use.
