Abstract
Description
Technical Field
[0001] The technology disclosed herein relates to heat insulation panels for vehicles. Background Technology
[0002] Heat sources such as engines or exhaust pipes are located under the floor of vehicles. In order to suppress the heat transfer from these heat sources to the vehicle body, heat shields are usually installed (for example, see Japanese Patent Application Publication No. 2013-6503).
[0003] The heat insulation panel is made of sheet-like metal materials and is fixed to the vehicle frame by multiple fastening points. Furthermore, it is known to form protrusions called reinforcing ribs on the heat insulation panel to improve rigidity. Traditionally, when the heat insulation panel is enlarged, the load around the fastening points increases due to increased weight and shape deformation, leading to insufficient local strength near the fastening points. Therefore, as a technique to strengthen the area around the fastening points, a structure with attached flat reinforcing plates is employed. However, simple flat reinforcing plates have limited reinforcement range and sometimes cannot achieve sufficient rigidity improvement. Additionally, depending on the shape of the reinforcing plate, positional misalignment or rotation can easily occur during manufacturing, making it difficult to maintain consistent quality.
[0004] Traditional insulation panels often struggle to adequately address localized strength deficiencies around fastener points, particularly in larger panels where deformation and vibration near these points become problematic. Furthermore, in structures employing reinforcing plates, inappropriate shape or placement not only limits reinforcement effectiveness but also leads to rotation and positional misalignment, resulting in inconsistent manufacturing quality. Additionally, using complex-shaped reinforcing plates increases manufacturing steps and costs. Therefore, there is an urgent need for an insulation panel that effectively improves rigidity around fastener points while offering excellent manufacturability and positional stability. Utility Model Content
[0005] The vehicle heat insulation plate of this utility model has: a body portion, which is fixed to the vehicle frame and has fastening holes, and has reinforcing ribs arranged in a manner that includes the fastening holes; and a reinforcing portion, which is installed on the main surface of the body portion, has a base portion covering the fastening holes and a plurality of flange portions extending from the base portion along the main surface of the body portion, and the reinforcing portion is provided with dots fixed to the body portion.
[0006] The reinforcing part can be formed in a Y-shape in the front view.
[0007] The reinforcing part can be a plate-shaped component.
[0008] Therefore, the reinforcement section has a roughly Y-shaped appearance in the front view. Multiple dots arranged around the fastening holes distribute the load in multiple directions, significantly improving the rigidity around the fastening points. Furthermore, the Y-shaped structure makes the reinforcement section less prone to rotation, thus ensuring stable installation and improving manufacturing quality. Attached Figure Description
[0009] Figure 1 This is a front view of the insulation panel. Detailed Implementation
[0010] The embodiments of this utility model are described with reference to the accompanying drawings.
[0011] like Figure 1 As shown, the vehicle heat insulation plate 10 of this embodiment is a heat insulation component installed on the lower part of the vehicle body, used to cover heat sources such as the engine, exhaust pipe, or parking brake. The heat insulation plate 10 is disposed between the heat source and the vehicle body and has the function of suppressing heat transfer. The heat insulation plate 10 is composed of plate-shaped components such as metal plates, and has concave and convex shapes formed according to the shape of the heat source.
[0012] The heat insulation panel 10 includes a main body and a reinforcing part 15 installed on the main body.
[0013] The main body includes a first part 11, a second part 12 disposed at an inclination relative to the first part 11, and a reinforcing rib 13 formed across the first part 11 and the second part 12. The first part 11, the second part 12, and the reinforcing rib 13 are formed, for example, by stamping a single sheet of flat plate.
[0014] Part 11 is a plate-like portion that serves as a fastening point for the vehicle. Figure 1 The middle part extends vertically, and its upper end is connected to the second part 12. A fastening hole 14 is formed in the first part 11, which extends through the thickness direction of the plate, and fasteners (bolts, etc.) are inserted into it.
[0015] The second part 12 is a plate-like portion disposed below the first part 11, and is inclined at a predetermined angle (not 180 degrees) relative to the first part 11. Thus, the heat insulation plate 10 can be arranged according to the shape of the vehicle body and the shape of the heat source.
[0016] The reinforcing rib 13 is a convex portion spanning the first portion 11 and the second portion 12. The reinforcing rib 13 includes a first reinforcing rib 13A formed in the first portion 11 and a second reinforcing rib 13B formed in the second portion 12. The first reinforcing rib 13A and the second reinforcing rib 13B are continuous and integrally formed. By protruding from the surfaces of the first portion 11 and the second portion 12, the reinforcing rib 13 improves the rigidity of both portions and suppresses springback deformation at the connection between them.
[0017] The fastening hole 14 is formed in the first reinforcing rib portion 13A and is a hole that penetrates the reinforcing rib portion 13 along the thickness direction of the plate. By inserting the fastener into the fastening hole 14, the heat insulation plate 10 is fixed to the vehicle body. By providing the fastening hole 14 on the reinforcing rib portion 13, the rigidity near the fastening point can be improved, thereby suppressing the overall deformation of the heat insulation plate 10.
[0018] The heat insulation panel 10 also includes a reinforcing portion 15 mounted on the main surface of the first part 11. The reinforcing portion 15 is a plate-shaped reinforcing member used to strengthen the first part 11. The reinforcing portion 15 integrally has a base 15A, and a first flange portion 15B and a second flange portion 15C extending from the base 15A in a predetermined direction, and is generally Y-shaped in a front view.
[0019] The base 15A is disposed above the area in the reinforcing rib 13 where the fastening hole 14 is formed. The base 15A has the same protruding shape as the reinforcing rib 13 and has a through hole formed at the position where it overlaps with the fastening hole 14. The reinforcing part 15 is fixed to the first part 11 by a fastener inserted through the through hole and the fastening hole 14. In addition, the base 15A has a first dot P1 above the fastening hole 14, at which the base 15A is fixed to the reinforcing rib 13.
[0020] The first flange portion 15B is an extension that extends from the lower end of the base portion 15A along the main surface of the first portion 11. The lower end of the first flange portion 15B protrudes further downward relative to the lower end of the base portion 15A and the lower end of the reinforcing rib portion 13. In addition, the first flange portion 15B is provided with a second dot P2 located below the fastening hole 14, at which the first flange portion 15B is fixed to the first portion 11.
[0021] The second flange portion 15C extends from the lower end of the base portion 15A toward the side opposite to the first flange portion 15B, and is also provided along the main surface of the first portion 11. The lower end of the second flange portion 15C also protrudes downward relative to the lower ends of the base portion 15A and the reinforcing rib portion 13. In addition, the second flange portion 15C is provided with a third dot P3 located below the fastening hole 14, at which the second flange portion 15C is fixed to the first portion 11.
[0022] With the above structure, the reinforcing part 15 is roughly Y-shaped in the front view, consisting of a base 15A and a first flange 15B and a second flange 15C extending to the left and right. The base 15A is centered on the fastening hole 14 of the reinforcing rib 13, and is fixed above by a first dot P1, while below it is fixed by the first flange 15B and the second flange 15C by a second dot P2 and a third dot P3, respectively. Therefore, the three dots P1, P2, and P3 are arranged around the fastening hole 14, which can disperse the load acting around the fastening point in multiple directions.
[0023] In the heat insulation plate 10 of this embodiment, since the fastening hole 14 is formed in the reinforcing rib 13, the area can be strengthened by the reinforcing rib 13, thereby suppressing local deformation around the fastening point and improving rigidity.
[0024] Furthermore, the reinforcing ribs 13 are continuously arranged across the first part 11 and the second part 12, which can simultaneously improve the rigidity of the two parts and suppress the springback deformation of their connection, thereby improving the forming accuracy of the heat insulation board 10 and obtaining a structure with high installation accuracy.
[0025] Furthermore, by placing the reinforcing part 15 around the fastening hole 14, the load concentrated at the fastening point can be effectively distributed. The reinforcing part 15 is a plate-shaped component, so the amount of reinforcement can be adjusted simply by adjusting its plate thickness, making it easy to design according to the required rigidity.
[0026] Furthermore, the reinforcing part 15 has a roughly Y-shaped structure, which can transfer the load to multiple directions, thereby improving the local reinforcement effect. In addition, the Y-shaped structure can also suppress the rotation of the reinforcing part 15, improve the stability of the installation position, and thus improve the manufacturing quality.
[0027] Furthermore, the reinforcing part 15 has a relatively simple shape and can be easily manufactured by stamping without the need for traditional deep drawing dies. This simplifies the manufacturing process and reduces costs while ensuring the necessary reinforcement effect.
[0028] As can be seen from the above, the heat insulation plate 10 of this embodiment can not only effectively improve the local strength around the fastening point, but also has excellent performance in terms of manufacturability and quality stability, thereby realizing a more reliable heat insulation plate for vehicles.
