Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an instrument panel with a foldable lower guard plate structure. Background Technology

[0002] As an important component of the car body, the interior system of a car, and the instrument panel system as the primary carrier of customer perception, not only play an important role in whether the interior design is aesthetically pleasing and whether the customer feels comfortable, but also bear the responsibility for passive safety, and safety is the top priority for customers.

[0003] Considering the need for passenger passive safety, many high-end cars are equipped with knee airbags. Experimental studies have shown that in some models, when the knee airbag deploys, the distance between the airbag's deployment path and the edge of the lower guard plate is small. In special collision deployment situations, the knee airbag may hit the sharp edge of the lower guard plate, and the lower guard plate may be ejected by the impact of the knee airbag deployment, causing secondary injury. Alternatively, the knee airbag may be torn by the lower guard plate during deployment and become ineffective, failing to provide protection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an instrument panel with a foldable lower guard plate structure. This solves the problem that in some vehicle models, when the knee airbag deploys, the distance between the knee airbag deployment path and the edge of the lower guard plate is small. In special collision deployment situations, the knee airbag may hit the sharp edge of the lower guard plate, and the lower guard plate may be ejected by the impact force of the knee airbag deployment, causing secondary injury, or the knee airbag may be torn by the lower guard plate during deployment and become ineffective, thus failing to provide protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an instrument panel with a foldable lower guard plate structure, comprising:

[0006] Dashboard skeleton;

[0007] The lower guard plate assembly includes a flange structure and a main body structure. A weakening groove is provided at the connection between the flange structure and the main body structure. The flange structure is connected to the instrument panel frame. The flange structure and the main body structure can be folded relative to each other using the weakening groove and form an arc-shaped bending surface on the outside of the fold.

[0008] The knee airbag is installed at the bottom of the dashboard frame and on the side of the flange structure and the curved bending surface of the main structure.

[0009] When the knee airbag bursts, it unfolds along the curved bending surface and the outer side of the main structure to avoid sharp surfaces coming into contact with the knee airbag and tearing it.

[0010] Preferably, the flange structure is connected to the instrument panel frame by fastening bolts.

[0011] Preferably, a tube beam bracket is installed between the other end of the fastening bolt and the instrument panel frame.

[0012] Preferably, the outer side of the instrument panel frame is provided with multiple slots, and the main structure is provided with multiple locking blocks that are adapted to the slots on the side near the instrument panel frame. The main structure is connected to the locking blocks through the slots.

[0013] Preferably, the thickness between the inner wall of the weakening groove and the outer wall on the other side of the lower guard plate assembly is 1 mm, and the width of the weakening groove is 1.2 mm.

[0014] Preferably, the thickness of the flange structure and the main structure gradually transitions to 2.5mm at the portion away from the weakening groove.

[0015] Preferably, the lower guard plate assembly is a modified plastic material made of polypropylene as the base material, combined with EPDM rubber and talc.

[0016] This utility model discloses an instrument panel with a foldable lower guard plate structure, which has the following beneficial effects:

[0017] 1. This dashboard features a foldable lower guard plate structure. In the event of a collision, the knee airbag deploys. Because the lower guard plate assembly employs a foldable design, its flanged structure and main body can fold relative to each other using weakening grooves, forming an arc-shaped bending surface on the outer side of the fold. This allows the knee airbag to deploy along the arc-shaped bending surface and the outer side of the main body structure during deployment, avoiding direct contact with the sharp edges of the lower guard plate assembly, thus preventing the risk of the airbag being punctured.

[0018] 2. The instrument panel with a foldable lower guard plate structure uses fastening bolts to ensure a firm connection between the lower guard plate assembly and the instrument panel frame and tube beam support, preventing the lower guard plate assembly from being ejected under the impact of airbag deployment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This application provides an instrument panel with a foldable lower guard plate structure, solving the problem in some vehicle models where, during knee airbag deployment, the distance between the knee airbag's deployment path and the edge of the lower guard plate is small. In special collision scenarios, the knee airbag may strike the sharp edge of the lower guard plate, potentially causing it to be ejected by the impact force and resulting in secondary injury, or the knee airbag may be torn and rendered ineffective during deployment. When a collision occurs, the knee airbag 3 deploys. Because the lower guard plate assembly 2 employs a foldable design, its flange structure 21 and main structure 22 can be folded relative to each other using the weakening groove 23, forming an arc-shaped bending surface on the outer side of the fold. This allows the knee airbag 3 to deploy along the arc-shaped bending surface and the outer side of the main structure 22, avoiding direct contact with the sharp edge of the lower guard plate assembly 2 and thus preventing the risk of the airbag being torn.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses an instrument panel with a foldable lower guard plate structure.

[0029] According to the appendix Figure 1-4 As shown, it includes:

[0030] Instrument panel frame 1;

[0031] The lower guard plate assembly 2 includes a flange structure 21 and a main structure 22. A weakening groove 23 is provided at the connection between the flange structure 21 and the main structure 22. The flange structure 21 is connected to the instrument panel frame 1, and the flange structure 21 and the main structure 22 can be folded relative to each other using the weakening groove 23 to form an arc-shaped bending surface on the outside of the fold.

[0032] The knee airbag 3 is installed at the bottom of the instrument panel frame 1 and is located on the side of the curved bending surface of the flange structure 21 and the main structure 22.

[0033] When the knee airbag 3 bursts, it deploys along the curved bending surface and the outer side of the main structure 22 to avoid the sharp surface from contacting the knee airbag 3 and tearing it.

[0034] When a collision occurs, the knee airbag 3 deploys. Because the lower guard plate assembly 2 employs a foldable design, its flanged structure 21 and main structure 22 can be folded relative to each other using the weakening groove 23, forming an arc-shaped bending surface on the outer side of the fold. This allows the knee airbag 3 to deploy along the arc-shaped bending surface and the outer side of the main structure 22 during deployment, avoiding direct contact with the sharp edge of the lower guard plate assembly 2, thus preventing the risk of the airbag being punctured.

[0035] Furthermore, a fastening bolt 4 connects the flange structure 21 to the instrument panel frame 1.

[0036] Furthermore, a tube beam bracket 5 is installed between the other end of the fastening bolt 4 and the instrument panel frame 1.

[0037] Fastening bolts 4 are used to enhance the connection strength between the lower guard plate assembly 2 and the instrument panel frame 1 and the tube beam bracket 5, preventing the lower guard plate assembly 2 from being ejected during airbag deployment. The tube beam bracket 5 supports the tube beam and serves as the mounting base for the knee airbag 3, and is fastened to the instrument panel frame 1 together with the lower guard plate assembly 2.

[0038] The instrument panel frame 1 serves as the main support structure for the instrument panel, providing a stable mounting platform for the lower guard plate assembly 2 and the knee airbag 3. The lower guard plate assembly 2 includes a flange structure 21 and a main body structure 22, and its foldable design protects the knee airbag 3 from being punctured during deployment.

[0039] The flange structure 21 is connected to the instrument panel frame 1 and can be folded relative to it using the weakening groove 23. The main structure 22, as the main part of the lower guard plate assembly 2, supports the entire guard plate structure and provides the necessary protective space for the knee airbag 3.

[0040] The weakening groove 23 is formed at the connection between the flange structure 21 and the main structure 22, allowing the guard plate to fold smoothly when the airbag deploys. The knee airbag 3 is installed at the bottom of the instrument panel frame 1 and deploys upon vehicle collision to protect the driver's knees.

[0041] Furthermore, multiple slots are provided on the outer side of the instrument panel frame 1, and multiple locking blocks that are adapted to the slots are provided on the side of the main structure 22 near the instrument panel frame 1. The main structure 22 is connected to the locking blocks through the slots.

[0042] Furthermore, the thickness between the inner wall of the weakening groove 23 and the outer wall on the other side of the lower guard plate assembly 2 is 1 mm, and the width of the weakening groove 23 is 1.2 mm.

[0043] Furthermore, the thickness of the flange structure 21 and the main structure 22, which are far from the weakening groove 23, gradually transitions to 2.5mm.

[0044] Furthermore, the lower guard plate assembly 2 is a modified plastic material made of polypropylene as the base material, combined with EPDM rubber and talc.

[0045] When a collision occurs, the knee airbag 3 deploys. Because the lower guard plate assembly 2 employs a foldable design, its flanged structure 21 and main structure 22 can be folded relative to each other using the weakening groove 23, forming an arc-shaped bending surface on the outer side of the fold. This allows the knee airbag 3 to deploy along the arc-shaped bending surface and the outer side of the main structure 22 during deployment, avoiding direct contact with the sharp edge of the lower guard plate assembly 2, thus preventing the risk of the airbag being punctured.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
