Description

Technical Field

[0001] This invention belongs to the field of automotive component technology, specifically relating to a fuel tank cover protection device. Background Technology

[0002] The fuel tanks of medium or heavy trucks are generally located on both sides of the chassis, and are basically exposed (except for tractor units which have side protection in the left and right directions of the vehicle). Without any protective covering, stones and other objects during driving can easily damage the fuel tanks, especially in the front and rear directions. Summary of the Invention

[0003] The purpose of this invention is to provide a fuel tank cover protection device to solve the problem that existing fuel tanks lack covers, which easily leads to fuel tank damage.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A fuel tank cover protection device is provided, which is respectively arranged in the front and rear directions of the fuel tank and is composed of protective devices with the same structure. The protective device includes a protective plate, a latch, a washer, a countersunk bolt, a gasket and a nut.

[0006] The protective plate has flanges around its perimeter pointing toward the fuel tank. Multiple latches are arranged parallel to each flange, and each latch is fixedly connected to the protective plate by countersunk bolts, washers, gaskets, and nuts.

[0007] Furthermore, the fuel tank is fixed to both sides of the vehicle chassis via fuel tank accessories, which include a fuel tank bracket assembly, fuel tank cable ties, a fuel tank bracket gasket, a fuel tank cable tie gasket, a pin bolt, and a pin fixing nut. The fuel tank bracket assembly is fixedly connected to the vehicle chassis by bolts. The fuel tank is mounted on the fuel tank bracket, and a fuel tank bracket gasket is placed between the fuel tank bracket and the fuel tank. After surrounding the fuel tank, the fuel tank cable ties are connected to the fuel tank bracket via pin bolts and pin fixing nuts, and a fuel tank cable tie gasket is placed between the fuel tank cable ties and the fuel tank.

[0008] Furthermore, the latch of the lock faces outwards.

[0009] Furthermore, the latches corresponding to the fuel tank bracket assembly are engaged with the fuel tank cable ties and the fuel tank bracket assembly, and are fixedly connected to the fuel tank bracket assembly by locking nuts.

[0010] Furthermore, the buckle corresponding to the fuel tank cable tie engages with the fuel tank cable tie.

[0011] Furthermore, the protective plate is made of flexible rubber, which facilitates the pre-assembly of the buckle, fuel tank cable ties, and fuel tank bracket assembly.

[0012] Furthermore, the latch is a plastic latch plate with a boss at the connection end with the protective plate. The recessed surface of the boss fits into the head of the countersunk bolt. When the latch is assembled with the protective plate, the boss is pressed into the mounting hole of the protective plate. A U-shaped groove structure is provided at the mounting point of the latch with the fuel tank cable tie and the fuel tank bracket assembly. During assembly, the U-shaped groove is embedded in the fuel tank cable tie, and the end of the U-shaped groove of the latch corresponding to the fuel tank bracket assembly abuts against the side of the fuel tank bracket assembly. The inner surface of the latch fits against the inner surface of the fuel tank bracket assembly.

[0013] The beneficial effects of this invention are:

[0014] This technical solution uses a protective plate structure to add a cover to the front and rear of the fuel tank, reducing the failure rate of the fuel tank due to collision, and the added cover does not affect the original structural design or ease of maintenance.

[0028] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.

[0029] like Figure 4 and Figure 5 As shown, the fuel tank involved in this application is the conventional fuel tank 11. No improvements have been made in the technical solution of this application. According to conventional installation technology, the fuel tank is fixed to both sides of the vehicle chassis by fuel tank accessories. Under normal circumstances, the fuel tank is fixed by two sets of fuel tank accessories. The structure of each set of fuel tank accessories is the same, and will not be described again here.

[0030] The fuel tank accessory of this application includes a fuel tank bracket assembly 12. The fuel tank bracket assembly of this application is made of L-shaped metal material and is fixedly connected to the vehicle chassis by bolts. The bottom surface and adjacent side surfaces of the fuel tank are provided on the fuel tank bracket assembly. A fuel tank bracket gasket 14 is provided between the fuel tank and the fuel tank bracket assembly to avoid wear and other issues between the fuel tank and the fuel tank bracket.

[0031] After the fuel tank cable tie 13 surrounds the upper bottom surface and the other side of the fuel tank 11, its two ends are connected to the fuel tank bracket assembly by pin bolts 17 and pin fixing nuts 18, and a fuel tank cable tie gasket 15 is provided between the fuel tank cable tie and the fuel tank.

[0032] like Figures 1 to 3 As shown, the fuel tank cover protection devices of this application are respectively installed in the front and rear directions of the fuel tank, that is, at both ends. The protection devices at both ends have the same structure and can be used interchangeably.

[0033] The protective device includes a protective plate 1, a latch 2, a washer 3, a countersunk bolt 4, a gasket 5, and a nut 6. The protective plate of this application has flanges on all four sides facing the fuel tank. In this embodiment, each flange has three mounting holes. In other embodiments of this application, the number of mounting holes is designed as needed. The protective plate of this application is a flexible rubber body, which facilitates the pre-installation of the latch with the fuel tank cable tie and fuel tank bracket assembly.

[0034] Taking the above embodiment as an example, three latches are fixedly installed on each side of the protective plate. In this embodiment, the latches are fixedly connected to the protective plate by countersunk bolts, washers, gaskets, and nuts. Figure 2 , Figure 3 , Figure 5 , Figure 10 and Figure 11 As shown, the latch of this application is a plastic latch plate structure. A boss is provided at the connection end between the latch and the protective plate, and a recessed surface is provided on the opposite side of the boss. The mounting hole on the latch is provided on the boss. When the countersunk bolt is inserted into the mounting hole of the latch, the recessed surface fits against the head of the countersunk bolt. Furthermore, when the latch is assembled with the protective plate, the boss end is pressed into the mounting hole of the protective plate. A washer is provided between the countersunk bolt and the recessed surface, and a washer is fitted on the countersunk bolt on the outside of the protective plate.

[0035] like Figures 6 to 11 As shown, in the technical solution of this application, the buckle is a plastic buckle plate. A U-shaped groove structure is provided at the installation position of the buckle, fuel tank cable tie and fuel tank bracket assembly. During assembly, the U-shaped groove is embedded in the fuel tank cable tie and the end of the U-shaped groove of the buckle corresponding to the fuel tank bracket assembly abuts against the side of the fuel tank bracket assembly. The inner surface of the buckle is in contact with the inner surface of the fuel tank bracket assembly.

[0036] The above are preferred embodiments of the present invention. The basic principles and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention.
