Description

Technical Field

[0001] This application relates to the field of automotive parts, and in particular to a fuel tank securing strap for automobiles. Background Technology

[0002] A fuel tank is a storage device used to store fuel to provide sufficient fuel for a vehicle's operation. In existing related technologies, to ensure the stability of the fuel tank's installation, it is fixed to the vehicle's frame using several fixing straps. Typically, the fixing straps are also fitted with a cushioning sleeve, which has a "U"-shaped cross-section, with the side of the cushioning sleeve without an opening facing the fuel tank. This reduces the rate of wear between the fuel tank and the fixing straps due to vibrations during vehicle operation.

[0003] Regarding the aforementioned technologies, after prolonged use, the buffer sleeve may slip and misalign relative to the fixing belt due to vibrations during driving. Summary of the Invention

[0004] To reduce the occurrence of slippage and misalignment of the buffer sleeve during vehicle operation, this application provides a fuel tank fixing strap.

[0005] The technical solution for a car fuel tank fixing strap provided in this application is as follows:

[0006] A car fuel tank fixing strap includes a fixing strap body and a buffer sleeve. The fixing strap body has a plurality of bent sections located at both ends of the fixing strap body. The curvature of each of the bent sections is greater than π / 2. The buffer sleeve is fitted onto the fixing strap body, and the ends of the buffer sleeve are covered by the bent sections. The buffer sleeve is flexible.

[0007] By adopting the above technical solution, the bending section increases the resistance of the buffer sleeve sliding along the fixed belt, making it less likely for the buffer sleeve to slip or become misaligned during vehicle operation.

[0008] Optionally, the fixing belt body has a plurality of bolt holes through it, and the plurality of bolt holes are respectively located at both ends of the fixing belt body.

[0009] By adopting the above technical solution, it is easy to install the fixing strap body to the car frame by bolts.

[0010] Optionally, the material of the fixing belt body is metal.

[0011] By adopting the above technical solutions, it is easier to ensure the service life of the fixing belt body and reduce the occurrence of aging.

[0012] Optionally, the buffer sleeve is provided in the form of a tube that extends only at both ends.

[0013] By adopting the above technical solution, after the buffer sleeve is fitted onto the fixing belt body, the part of the fixing belt body in contact with the outside is reduced, which helps to reduce the situation where the fixing belt body is directly exposed to rainwater or water accumulation, thereby reducing the occurrence of corrosion of the fixing belt body.

[0014] Optionally, the end of the buffer sleeve is provided with an injection port, and the fixing strap body forms part of the sidewall of the injection port.

[0015] By adopting the above technical solution, after the buffer sleeve is fitted onto the fixing belt body, sealant is injected between the buffer sleeve and the fixing belt body through the injection port, which will help to further ensure the sealing between the buffer sleeve and the fixing belt body.

[0016] Optionally, the cross-section of the fixing belt body is rectangular.

[0017] By adopting the above technical solution, it is easier for assembly personnel to slip the buffer sleeve onto one end of the fixing belt body, thereby reducing the occurrence of the buffer sleeve being stuck by the fixing belt body.

[0018] Optionally, the fixing strap body is fixedly mounted with an L-shaped reinforcing frame, one end of which is attached to the end of the buffer sleeve.

[0019] By adopting the above technical solution, on the one hand, it is easy to ensure the structural strength of the fixing belt body, and on the other hand, it is easy to block the slippage of the buffer sleeve through the L-shaped reinforcing frame, thereby reducing the occurrence of slippage and misalignment of the buffer sleeve during vehicle operation.

[0020] Optionally, the L-shaped reinforcing frame is welded to the fixing belt body.

[0021] By adopting the above technical solution, it is beneficial to reduce the processing difficulty when the fixing belt body is stamped and bent.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The bending section increases the resistance to the sliding of the buffer sleeve along the fixed belt, making it less likely for the buffer sleeve to slip or become misaligned during vehicle operation;

[0024] 2. After the buffer sleeve is fitted onto the fixing belt body, the part of the fixing belt body in contact with the outside is reduced, which helps to reduce the direct contact of the fixing belt body with rainwater or water accumulation, thereby reducing the occurrence of corrosion of the fixing belt body.

[0025] 3. After the buffer sleeve is fitted onto the fixing belt body, sealant is injected between the buffer sleeve and the fixing belt body through the injection port. This will help to further ensure the sealing between the buffer sleeve and the fixing belt body.

[0026] 4. The buffer sleeve is prevented from slipping, thereby reducing the occurrence of slippage and misalignment of the buffer sleeve during vehicle operation. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a fuel tank securing strap for automobiles. (Refer to...) Figure 1 and Figure 2 The automotive fuel tank fixing strap includes a fixing strap body 1 and a buffer sleeve 2.

[0034] Reference Figure 1 and Figure 3 The fixing strap body 1 is a rectangular strip, and it is curved according to the shape of the fuel tank to ensure a tight fit against the surface of the fuel tank. The fixing strap body 1 is made of metal, preferably steel, to balance service life and operating costs. The thickness of the fixing strap body 1 is 0.5 to 1.5 mm, and its width is 30 to 50 mm. Furthermore, to slow down the corrosion rate of the fixing strap body 1, a rust-preventive coating can be sprayed onto its surface.

[0035] Reference Figure 4 The fixing strap body 1 has a rectangular cross-section and a smooth surface. Two bolt holes 101 are formed through the fixing strap body 1 along its thickness direction. The two bolt holes 101 are located at both ends of the fixing strap body 1, and the openings of both bolt holes 101 face vertically, so as to facilitate the mounting of the fixing strap body 1 to the vehicle frame using bolts.

[0036] Reference Figure 2 and Figure 3The buffer sleeve 2 is a tubular structure extending only at both ends, meaning it has openings only at both ends to ensure a tight seal inside. The buffer sleeve 2 is flexible, and its material is preferably rubber. The buffer sleeve 2 is fitted over both ends of the fixing belt body 1, with its inner surface tightly adhering to the fixing belt body 1 to prevent water from easily penetrating between them. In some embodiments, the buffer sleeve 2 can be made transparent to facilitate observation of the corrosion of the fixing belt body 1 inside, reducing the likelihood of excessive corrosion that goes unnoticed and requires replacement.

[0037] Reference Figure 1 and Figure 2 The fixing strap body 1 has two bent sections 11, with the two bent ends located at both ends of the fixing strap body 1. The arc of the bent section 11 is greater than π / 2, and the unit of the arc of the bent section 11 is rad. In this embodiment, the arc of the bent section 11 is preferably π. The end of the buffer sleeve 2 covers the bent section 11, so that the buffer sleeve 2 bends along with the bent section 11 at the position of the bent section 11, thereby giving the buffer sleeve 2 greater resistance when it tends to slip, thus making the buffer sleeve 2 less likely to slip and misalign under the action of external force.

[0038] Reference Figure 3 The fixing strap body 1 is fixedly installed with two L-shaped reinforcing frames 3 by welding. The two L-shaped reinforcing frames 3 are located at both ends of the fixing strap body 1. One end of the L-shaped reinforcing frame 3 is attached to the end of the buffer sleeve 2, and the other end of the L-shaped reinforcing frame 3 is close to the bolt hole 101. This makes it less likely for the fixing strap body 1 to deform at the bending point, and also facilitates the blocking of the slippage of the buffer sleeve 2 by the L-shaped reinforcing frame 3, thereby further preventing the buffer sleeve 2 from slipping and misaligning under the action of external force.

[0039] Reference Figure 4 The end opening of the buffer sleeve 2 is provided with an injection port 201, and the fixing belt body 1 forms part of the side wall of the injection port 201, so that after the buffer sleeve 2 is put on the fixing belt body 1, sealant can be injected between the buffer sleeve 2 and the fixing belt body 1 through the injection port 201, thereby helping to further ensure the sealing between the buffer sleeve 2 and the fixing belt body 1.

[0040] The implementation principle of the automotive fuel tank fixing strap in this application embodiment is as follows: the bent section 11 increases the resistance of the buffer sleeve 2 sliding along the fixing strap body, and the L-shaped reinforcing frame 3 will hinder the slippage of the buffer sleeve 2, thereby making the buffer sleeve 2 less likely to slip or become misaligned during vehicle operation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
