A roof reinforcement structure

Abstract

This utility model discloses a roof reinforcement structure, belonging to the field of automotive roof technology. The roof reinforcement structure includes a roof base material (1), a roof fabric (2), and a reinforcing plate (3). The roof base material (1) is located below the roof fabric (2), and the reinforcing plate (3) is located at the front end of the roof base material (1) and below the roof base material (1), which strengthens the structural strength of the front end of the roof, making the front end of the roof less prone to deformation and ensuring the safety of the driver.

Description

Technical Field

[0001] This utility model belongs to the field of automotive roof technology, specifically relating to a roof reinforcement structure. Background Technology

[0002] The car roof is usually located on the top of the vehicle body. As a key structure of the car, it enhances the overall rigidity of the vehicle body. When the vehicle is involved in a collision, rollover, or crush, it can reduce the extent of roof deformation, providing safety protection and support for the occupants.

[0003] Currently, most car roofs consist of a base material and fabric, but the base material is not strong enough, making the front end of the roof prone to deformation. Chinese utility model patent CN223252907 U, published on August 22, 2025, discloses a roof reinforcement structure. This structure uses magnetic plates evenly distributed at one end on the roof, with the other end magnetically attached to the car body frame to strengthen the roof structure and prevent collapse. However, the front end of the roof lacks reinforcement, making it susceptible to deformation during collisions, rollovers, and crushing, thus affecting the structural safety of the car body. Utility Model Content

[0004] The present invention aims to provide a roof reinforcement structure that can strengthen the front end of a car roof and prevent the front end of the car roof from deforming.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ceiling reinforcement structure, comprising a ceiling substrate and a ceiling fabric, wherein the ceiling substrate is located below the ceiling fabric, characterized in that: it further comprises a reinforcing plate, wherein the reinforcing plate is connected to the ceiling substrate.

[0006] Furthermore, the reinforcing plate is located at the front end of the ceiling substrate and below the ceiling substrate.

[0007] Furthermore, a hot melt adhesive layer is provided between the reinforcing plate and the ceiling substrate, and the reinforcing plate and the ceiling substrate are fixedly bonded by the hot melt adhesive layer.

[0008] Furthermore, the side where the reinforcing plate and the ceiling substrate are attached is arc-shaped.

[0009] Furthermore, the reinforcing plate extends from one end of the ceiling substrate to the other end.

[0010] Furthermore, the front end of the ceiling substrate is arc-shaped, and the curvature of the reinforcing plate is consistent with that of the front end of the ceiling substrate.

[0011] The technical effect of this utility model is as follows: by adding a reinforcing plate to the front end of the car roof, the structural strength of the front end of the car roof is enhanced; a hot melt adhesive layer is provided between the reinforcing plate and the roof substrate, and the reinforcing plate and the roof substrate are connected by the hot melt adhesive. When the front roof substrate deforms, the deformed area can be pulled back by the reinforcing plate. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation.

[0014] like Figure 1 and Figure 2 As shown, a ceiling reinforcement structure includes a ceiling substrate 1 and a ceiling fabric 2, with the ceiling substrate 1 located below the ceiling fabric 2. It also includes a reinforcing plate 3 connected to the ceiling substrate 1. The ceiling substrate 1 provides structural support and shaping, ensuring the stability of the ceiling shape; the ceiling fabric 2 primarily enhances the interior texture; and the reinforcing plate 3 strengthens the rigidity of the ceiling structure, ensuring that the ceiling is not easily deformed upon impact.

[0015] Specifically, such as Figure 3 As shown, the reinforcing plate 3 is located at the front end of the roof substrate 1 and below the roof substrate 1, which strengthens the structural strength of the front end of the roof, making the front end of the roof less prone to deformation and ensuring the safety of the driver.

[0016] Specifically, such as Figure 3 As shown, a hot melt adhesive layer 4 is provided between the reinforcing plate 3 and the ceiling substrate 1. The reinforcing plate 3 and the ceiling substrate 1 are fixedly bonded by the hot melt adhesive layer 4, connecting the reinforcing plate 3 and the ceiling substrate 1 into a whole, which strengthens the structure of the front end of the ceiling and makes the structure of the parts more stable. When the front ceiling substrate deforms, the deformed area can be pulled back by the reinforcing plate 3, thereby improving the durability of the ceiling.

[0017] Specifically, such as Figure 3 As shown, the side where the reinforcing plate 3 and the ceiling substrate 1 are attached is curved. The reinforcing plate 3 as a whole is a long block structure with a curved shape, which can avoid stress concentration, reduce the risk of breakage, and improve the structural strength of the entire ceiling.

[0018] Specifically, such as Figure 3 As shown, the reinforcing plate 3 extends from one end of the roof substrate 1 to the other end, distributing the external force on the roof evenly across the entire plate surface, reducing stress concentration, and further enhancing the car roof's resistance to bending and deformation.

[0019] Specifically, such as Figure 3 As shown, the front end of the ceiling substrate 1 is arc-shaped, and the curvature of the reinforcing plate 3 is consistent with that of the front end of the ceiling substrate 1, so that the ceiling substrate 1 and the reinforcing plate 3 are completely attached, the force is more even, local stress concentration is avoided, and the overall load-bearing capacity of the ceiling is improved.

[0020] The working process of this roof reinforcement structure is as follows: a reinforcing plate 3 is added to the front end of the roof, and the reinforcing plate 3 is fixed to the back of the roof substrate 1 by a hot melt adhesive layer 4; when the roof deforms, the deformed area can be pulled back by the reinforcing plate 3. The roof substrate 1, roof fabric 2, and reinforcing plate 3 have the same bending direction and bending arc and fit tightly together, which improves the structural strength of the car roof and makes the force on the roof evenly and directly transmitted to the reinforcing plate 3.

[0021] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
