Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automotive front bulkheads, and specifically relates to a low-VOC automotive front bulkhead with a reinforced front bulkhead structure. Background Art
[0002] The dash board refers to the partition between the engine compartment and the passenger compartment. It is connected to the floor and the front pillars and is installed under the upper front bulkhead cover. There are many apertures on the dash board for the use of operating cables, tie rods, pipelines, and wire harnesses, and it also needs to cooperate with the installation positions of components such as pedals and steering columns.
[0003] When a vehicle undergoes a frontal collision, the front bulkhead structure needs to effectively absorb and disperse the collision energy to reduce the intrusion into the passenger compartment and protect the safety of the occupants. If the front bulkhead structure is not strong enough, it may not be able to provide sufficient energy absorption capacity. Therefore, this application designs a low-VOC automotive front bulkhead with a reinforced front bulkhead structure to improve the energy absorption effect of the front bulkhead structure. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides a low-VOC automotive front bulkhead with a reinforced front bulkhead structure.
[0005] The technical solution of the utility model is: a low-VOC automotive front bulkhead with a reinforced front bulkhead structure, including a plate body with a cavity inside, several sliding rods perpendicular to the plate body and one end of which extends into the cavity, and an airbag column and an airbag assembly arranged in the cavity. One end of the airbag column is connected to the sliding rod, the other end of the airbag column is connected to the cavity, and the airbag column is connected to the airbag assembly through a pipeline. The airbag assembly is composed of several airbag rods evenly distributed in the cavity.
[0006] Further, a first spring is arranged inside the airbag column.
[0007] Explanation: By setting the first spring, the airbag column can be restored to its original state after the impact object is displaced.
[0008] Further, a rhombic frame is arranged between the sliding rod and the cavity. The rhombic frame is composed of four struts sequentially hinged by hinge rods. The airbag column is vertically arranged inside the rhombic frame, and a second spring is horizontally arranged inside the rhombic frame.
[0009] Explanation: Setting the rhombic frame can effectively disperse the impact force, disperse the longitudinal impact force to both sides, and improve the anti-impact effect.
[0010] Further, the sliding rod is elastic.
[0011] Description: When the impact force is relatively weak, the elasticity of the sliding rod can buffer the impact force. When the impact force is strong, the elasticity of the sliding rod can also offset a part of the impact force, both of which can reduce the operation amount of the internal airbag column and the airbag assembly, thereby improving the service life of the front apron and its internal structure.
[0012] Furthermore, a circular piece or a rectangular piece is provided at the other end of the sliding rod.
[0013] Description: The circular piece or the rectangular piece can increase the stress area of the sliding rod, thereby improving the impact resistance of the front apron.
[0014] The beneficial effects of the present utility model are as follows:
[0015] The front apron of the motor vehicle of the present utility model is provided with a sliding rod and an airbag column to buffer the external impact, and due to the force buffering of the airbag column, a plurality of airbag rods are uniformly expanded, so as to perform a reverse and uniform support on the surface of the front apron, improve the impact resistance of the front apron, and achieve the reinforcement effect on the front apron.

[0022] The following further describes the present utility model in more detail in combination with specific embodiments to better reflect the advantages of the present utility model.
[0023] Embodiment 1
[0024] A low-VOC front apron for a motor vehicle with a reinforced front enclosure structure, such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, it includes a plate body 1 with a cavity inside, several sliding rods 2 perpendicular to the plate body 1 and with one end extending into the cavity, and an airbag column 3 and an airbag assembly arranged in the cavity. One end of the airbag column 3 is fixedly connected to the sliding rod 2, the other end of the airbag column 3 is fixedly connected to the cavity, and the airbag column 3 is communicated with the airbag assembly through a pipeline. The airbag assembly is composed of several airbag rods 4 evenly distributed in the cavity. A first spring is arranged inside the airbag column 3. The sliding rod 2 is rigid, such as made of stainless steel material, and the plate body 1 is made of a TPE material with a low VOC content.
[0025] The working principle of the low-VOC automotive front panel with the above-reinforced front enclosure structure is as follows: When the plate body 1 is impacted, the impact object in contact with the sliding rod 2 presses the sliding rod 2 to move downward, so that the airbag column 3 is squeezed, and the airbag rods 4 of the airbag assembly expand evenly, providing a reverse support for the surface of the plate body 1. When the impact object is removed, the first spring causes the airbag column 3, the airbag assembly, and the sliding rod 2 to return to their original states.
[0026] Embodiment 2
[0027] The difference between this embodiment and Embodiment 1 is that, as Figure 4 shown in the figure, a diamond-shaped frame 5 is arranged on the airbag column 3. The diamond-shaped frame 5 is composed of four struts sequentially hinged by hinge rods. The airbag column 3 is vertical and connected between the top and bottom of the diamond-shaped frame 5, and a second spring is horizontally connected between the left and right parts of the diamond-shaped frame 5.
[0028] The difference in the working principle of this embodiment from that of Embodiment 1 is that when the airbag column 3 is compressed and buffered by force, the upper and lower sides of the diamond-shaped frame 5 are compressed synchronously, enabling the airbag column 3 to normally drive the reverse support of the airbag assembly, while the left and right sides of the diamond-shaped frame 5 pull the second spring to stretch, which can disperse the longitudinal impact force to both sides and improve the impact resistance of the front panel.
[0029] Embodiment 3
[0030] The difference between this embodiment and Embodiment 1 is that, as Figure 5 shown in the figure, a rectangular piece is arranged at the other end of the sliding rod 2.
[0031] The difference in the working principle of this embodiment from that of Embodiment 1 is that setting the rectangular piece can increase the contact area between the sliding rod 2 and the impact object, thereby improving the impact resistance of the front panel.
[0032] Embodiment 4
[0033] The difference between this embodiment and Embodiment 1 is that the sliding rod 2 is elastic, such as made of rubber material.
[0034] The difference in the working principle of this embodiment from that of Embodiment 1 is that when the impact force is relatively weak, the elasticity of the slide bar 2 can buffer the impact force, and when the impact force is strong, the elasticity of the slide bar 2 can also offset a part of the impact force, both of which can reduce the operation amount of the internal airbag column 3 and the airbag assembly, thereby improving the service life of the front bulkhead and its internal structure.
