Automobile fuel tank protection plate

Abstract

The utility model discloses an automobile fuel tank protection plate which comprises a protection plate body and an installation hole formed in the protection plate body, a screw penetrates through the installation hole and enables the protection plate body to be installed at the position of a fuel tank at the bottom of an automobile, buffering pads are evenly arranged on the inner concave face of the protection plate body and make contact with the outer surface of the fuel tank, and a cavity of each buffering pad is provided with a partition. The partitions are communicated with each other through the narrow slits, and the side face of the buffer pad is inwards concaved towards the cavity. The buffer pad fills the gap and is in contact connection with the outer surface of the oil tank. When the protective plate touches the ground, the protective plate is extruded, and the partition back of the buffer pad is bent and deformed. And as the inner wall of the buffer cushion is extruded, the concave part on the side surface of the buffer cushion protrudes outwards, and the buffer cushion is further compressed. In the whole process, the buffer pad not only absorbs energy, but also plays a role in isolating the oil tank. In addition, the partitioned narrow slits ensure that the buffering cushion cannot be shrunken immediately when being pressed, so that the buffering effect is more linear and softer, and the possibility that the oil tank is sunken and even broken is greatly reduced.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive fuel tank guard plate. Background Technology

[0002] A fuel tank skid plate is a protective device primarily installed on the bottom or side of the fuel tank to prevent damage from rough roads or flying debris. The skid plate is bolted to the vehicle and maintains a certain distance from the fuel tank. However, in extreme cases, such as encountering very rough terrain that causes the skid plate to dent and intrude into the gap between it and the fuel tank, it may cause severe deformation or rupture of the fuel tank. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a car fuel tank guard plate includes a guard plate and mounting holes provided on the guard plate. Screws pass through the mounting holes and install the guard plate at the fuel tank position on the bottom of the car. The guard plate is characterized in that: a buffer pad is uniformly provided on the concave surface of the guard plate, which is in contact with the outer surface of the fuel tank. The cavity of the buffer pad has partitions, and the partitions are interconnected by narrow slits. The side of the buffer pad is concave and faces the cavity.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] As a preferred embodiment of the automotive fuel tank guard plate of this utility model, an air inlet is provided on the buffer pad, and the air inlet is located on the opposite side of the concave surface of the guard plate.

[0007] As a preferred embodiment of the automotive fuel tank guard plate of this utility model, the buffer pad is provided with clearance holes corresponding to the mounting holes.

[0008] In a preferred embodiment of the automotive fuel tank guard plate of this utility model, the buffer pad is divided into grid strips, and the bottom of the grid strips is provided with a venting groove, which is a narrow slit between the partitions.

[0009] In a preferred embodiment of the automotive fuel tank guard plate of this utility model, both the buffer pad and the mesh strip are made of soft rubber.

[0010] In a preferred embodiment of the automotive fuel tank guard plate of this utility model, the side of the buffer pad that contacts the outer surface of the fuel tank has a protrusion.

[0011] In a preferred embodiment of the automotive fuel tank guard plate of this utility model, the protrusion corresponds to the top of the chamber separated by the grid strip.

[0012] The beneficial effects of this utility model are as follows: the buffer pad fills the gap and is in contact with the outer surface of the fuel tank. When the bottom of the protective plate touches the ground, the protective plate is squeezed. At this time, the back pressure of the buffer pad is bent and deformed. Due to the compression of the inner wall of the buffer pad, the concave part on its side bulges outward, which further compresses the buffer pad. In the whole process, the buffer pad not only absorbs energy but also plays the role of isolating the fuel tank. In addition, the narrow slit of the partition ensures that the buffer pad will not collapse immediately when compressed. Therefore, the buffering effect is more linear and gentle, which greatly reduces the possibility of the fuel tank denting or even breaking. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1 to 4 This embodiment of the present invention provides a car fuel tank guard plate, including a guard plate 100 and mounting holes 101 provided on the guard plate 100. Screws pass through the mounting holes 101 and the guard plate 100 is installed at the fuel tank position at the bottom of the car. The inner concave surface of the guard plate 100 is uniformly provided with buffer pads 200, which are in contact with the outer surface of the fuel tank. The chambers 200a of the buffer pads 200 are partitioned, and the partitions are interconnected by narrow slits. The side surface 200b of the buffer pads 200 is concave and faces the chambers 200a.

[0027] Specifically, the protective plate 100 is made of two main materials: plastic and metal, each with strong mechanical strength. Most protective plates 100 are installed on the bottom of the car to cover the fuel tank by drilling holes in their surface and screwing them on. The buffer pad 200 is installed in the gap between the protective plate 100 and the fuel tank, specifically on the concave surface of the protective plate 100. After the protective plate 100 is installed, the buffer pad 200 fills the gap and contacts the outer surface of the fuel tank. When the bottom of the protective plate 100 touches the ground, the protective plate 100 is compressed, and the buffer pad 200 is bent and deformed by the pressure. Due to the compression of the inner wall of the buffer pad 200, the concave side 200b of the buffer pad 200 bulges outward, further compressing the buffer pad 200. Throughout the process, the buffer pad 200 acts as an energy absorber and isolates the fuel tank, reducing the occurrence of fuel tank dents or even ruptures.

[0028] For example, the buffer pad 200 is connected to an air inlet 201, which is located on the opposite side of the concave surface of the guard plate 100. The air inlet 201 allows a certain amount of gas to be injected into the cavity of the buffer pad 200 after the guard plate 100 is installed, so that the buffer pad 200 has a stronger elastic cushioning function and fills the gap between the guard plate and the fuel tank, making the guard plate 100 more firmly installed at the bottom of the car.

[0029] For example, the buffer pad 200 is provided with a clearance hole 204 corresponding to the mounting hole 101 in order to avoid the guard plate mounting hole 101;

[0030] For example, the partition of the buffer pad 200 is a mesh strip 202, and the bottom of the mesh strip 202 is provided with a venting groove 202a. The venting groove 202a is a narrow slit between the partitions. The mesh strip 202 can make the buffer pad 200 more stable in terms of buffering the fuel tank and supporting it under normal conditions. In addition, the narrow slit in the mesh strip 202 prevents the buffer pad 200 from immediately collapsing when it is squeezed. Therefore, the buffering effect of the buffer pad is more linear and gentle, and thus the energy absorption effect of the fuel tank is better.

[0031] For example, both the cushioning pad 200 and the mesh strip 202 are made of soft rubber. This type of material has good elasticity, durability and airtightness when made into a hollow cushioning pad 200.

[0032] For example, the side of the buffer pad 200 that contacts the outer surface of the fuel tank has a protrusion 203. There is a certain distance between the protrusion 203 and the buffer pad 200. The uniform protrusion 203 will not affect the support of the fuel tank surface, and the certain distance can also improve the buffering effect of the buffer pad 200 on the fuel tank. At the same time, the protrusion 203 provides more space for releasing air pressure in the buffer pad 200.

[0033] For example, the protrusion 203 corresponds to the chamber 200a separated by the grid strip 202.
