Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a fuel tank strap assembly and a vehicle. Background Technology

[0002] Car fuel tanks are typically secured to the vehicle body using metal fuel tank straps. Existing fuel tank straps connect to the vehicle body via through holes at both ends and bolts that mate with mounting holes on the vehicle body, thus fixing the strap to the body and securing the fuel tank. However, due to gaps between the strap near the ends and the fuel tank, and the fuel tank's own breathing effect, the fuel tank is prone to shifting under extreme road conditions such as bumps, or during braking and acceleration / deceleration. This causes relative displacement between the fuel tank, the strap, and the vehicle body, resulting in wear and tear. Utility Model Content

[0003] In view of this, the present invention provides a fuel tank strap assembly and a vehicle to solve the problem that the fuel tank is prone to movement under extreme road conditions such as bumps, or during braking and acceleration / deceleration, which causes relative displacement between the fuel tank, the strap, and the vehicle body, resulting in wear.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, in one aspect, a fuel tank strap assembly is provided for connecting to the body of a vehicle. The fuel tank strap assembly includes:

[0037] The fuel tank shell has multiple lugs 3 on its front or rear side along the vehicle's direction of travel, and the multiple lugs 3 are spaced apart along the width direction of the vehicle.

[0038] Multiple straps 4 are provided, each strap 4 is connected to a lug 3, and the two ends of the strap 4 are respectively provided with a first bend 41 and a second bend 42. The first bend 41 and the lug 3 are adapted to be fixedly connected to the vehicle body by fasteners. The second bend 42 passes around the bottom surface of the fuel tank shell and is fixedly connected to the vehicle body. The second bend 42 and the first bend 41 are located on the front and rear sides of the fuel tank shell, respectively.

[0039] The fuel tank strap assembly provided in this embodiment has multiple lugs 3 fixedly installed on the fuel tank shell. One end of the strap 4 and the lugs 3 are simultaneously fixedly connected to the vehicle body, thereby connecting the fuel tank shell, the strap 4 and the vehicle body into a whole. This can effectively reduce the relative displacement between the fuel tank and the strap 4 or the vehicle body under extreme road conditions or during braking or acceleration and deceleration, which helps to reduce wear.

[0040] Specifically, a shock-absorbing pad is provided on the top surface of the fuel tank shell, and the top surface of the fuel tank shell is adapted to abut against the vehicle body through the shock-absorbing pad. The strap 4 passes under the fuel tank shell, and both ends of the strap 4 are fixedly connected to the vehicle body, thereby binding the fuel tank shell to the vehicle body. Among them, along the direction of vehicle travel, the first bend 41 and the second bend 42 located at both ends of the strap 4 are respectively located on the front and rear sides of the fuel tank shell.

[0041] Because in the relevant technology, the two ends of the strap 4 are directly connected to the vehicle body, resulting in gaps between the fuel tank shell and the area near the ends of the strap 4. Under extreme road conditions such as bumps, or during braking and acceleration / deceleration, the fuel tank shell moves significantly back and forth, causing wear between the fuel tank shell and the shock absorber and strap. As wear continues, the gap between the fuel tank shell and the vehicle body widens, further increasing the movement and creating a vicious cycle. Furthermore, as described below, the fuel tank shell is formed by welding a lower shell 1 and an upper shell 2, with flanges formed at the opening edges of the lower shell 1 and upper shell 2. When the movement of the fuel tank shell is large, these flanges are prone to colliding with the strap 4, causing localized wear on the strap 4. In severe cases, this can lead to the strap 4 breaking and the fuel tank detaching.

[0042] The fuel tank strap assembly provided in this embodiment connects and fixes the first bent portion 41, the lug 3, and the vehicle body into a whole using fasteners. Compared to the binding of the fuel tank shell with the strap 4 in related technologies, this effectively fixes the relative positions of the fuel tank shell, the strap 4, and the vehicle body, thereby greatly reducing or even avoiding the displacement of the fuel tank shell relative to the strap 4 or the vehicle body under extreme road conditions such as bumps, or during braking and acceleration / deceleration. This reduces wear and increases the service life of the fuel tank strap assembly. Additionally, the fasteners also limit the relative vertical displacement between the fuel tank shell and the vehicle body. Notably, the fuel tank shell assembly provided in this embodiment only provides the lug 3 on the front or rear side of the fuel tank shell, rather than on both sides, to reduce costs and improve material utilization.

[0043] In one embodiment, combined Figure 2 , Figure 3 and Figure 6 As shown, a bending plate 9 is fixedly connected to the side of the first bend 41 and / or the second bend away from the tank housing.

[0044] The fuel tank strap assembly provided in this embodiment improves the structural strength of the first bend 41 and / or the second bend 42 and reduces deformation by setting a bending plate 9.

[0045] Specifically, the bending plate 9 is used to support the first bend 41 and / or the second bend 42. The bending plate 9 has a fourth through hole 91 corresponding to the first through hole 411, which is used to allow fasteners to pass through and create clearance. Since the first bend 41 and / or the second bend 42 are made of sheet metal, they may deform under vibration during vehicle operation. By setting the bending plate 9, the structural strength of the bend of the first bend 41 and / or the second bend 42 can be improved, which helps to reduce deformation.

[0046] In one embodiment, combined Figure 5 and Figure 6As shown, the first bend 41 has a first through hole 411, and the lug 3 has a second through hole corresponding to the first through hole 411. The fastener includes a bolt, which passes through the first through hole 411 and the second through hole and is fixedly connected to the vehicle body.

[0047] Specifically, the fasteners include bolts or rivets. As one possible implementation, bolts are used as the fasteners, with corresponding threaded holes in the vehicle body structure. The shank of the bolt passes through the first through hole 411 and the second through hole and is screwed into the bolt hole to connect and fix the first bent portion 41, the lug 3, and the vehicle body. Alternatively, a fifth through hole is correspondingly provided on the vehicle body structure, with the shank of the bolt passing through the first through hole 411, the second through hole, and the fifth through hole, and the first bent portion 41, the lug 3, and the vehicle body connected and fixed by a nut thereon. As an additional implementation, rivets are used as the fasteners, with the rivets passing through the first through hole 411, the second through hole, and the fifth through hole, thereby connecting and fixing the first bent portion 41, the lug 3, and the vehicle body.

[0048] In one embodiment, combined Figure 2 and Figure 6 As shown, a reinforcing plate 6 is provided between the first bent portion 41 and the lug 3, and the reinforcing plate 6 has a third through hole corresponding to the first through hole 411.

[0049] The fuel tank strap assembly provided in this embodiment improves the connection stability and reliability of the first bend 41 and the lug 3 by providing a reinforcing plate 6.

[0050] Specifically, since the lug 3 is made of sheet metal, it is subject to certain bending deformation. Therefore, a reinforcing plate 6 is used to strengthen the structure at the lug 3 to reduce its deformation. The third through hole is used to provide clearance for the fastener to pass through the first through hole 411 and the second through hole.

[0051] Furthermore, the reinforcing plate 6 has an arc-shaped part 61 on the side near the oil tank housing. The curvature of the arc-shaped part 61 is adapted to the curvature of the flange of the lower housing 1 so that the arc-shaped part 61 and the lower housing 1 can form a surface contact when they collide, thereby increasing the contact area, reducing the pressure generated during the collision, and reducing the damage to the lower housing 1.

[0052] In one embodiment, combined Figure 2 , Figure 3 and Figure 6 As shown, metal liners 7 are installed inside the second and third through holes, and the shank of the bolt passes through the inside of the metal liners 7.

[0053] The fuel tank strap assembly provided in this embodiment, by setting a metal liner 7, allows it to bear the main load, rather than having the thinner sheet material directly bear the force, which helps to protect the structural integrity of the lug 3 and the first bend 41.

[0054] Specifically, the metal liner 7 has radial protrusions at both ends along its axial direction. The radial protrusions are adapted to abut against the sides of the lug 3 to limit the movement of the metal liner 7 relative to the lug 3 along its axial direction.

[0055] Since the bent portions of the lugs 3 and straps 4 are made of sheet metal, the material around these through holes is prone to deformation or even tearing when subjected to fastening forces and alternating loads generated by vehicle bumps and vibrations. By installing a metal liner 7, the load is primarily borne by the metal liner 7, rather than by the thinner sheet metal directly bearing the force, thus helping to protect the structural integrity of the lugs 3 and straps 4 themselves.

[0056] In one embodiment, combined Figure 2 , Figure 3 and Figure 6 As shown, rubber liners 8 are also installed inside the second and third through holes, and the rubber liners 8 are fitted over the metal liners 7.

[0057] The fuel tank strap assembly provided in this embodiment uses a rubber liner 8 to reduce vibration transmission and noise, and provides elastic compensation.

[0058] Specifically, the rubber liner 8 also has radial protrusions at both ends along its axial direction. The two radial protrusions of the rubber liner 8 abut against the sides of the lug 3, and the two radial protrusions of the metal liner 7 abut against the two ends of the rubber liner 8 along its axial direction, thereby limiting the relative displacement of the metal liner 7 and the rubber liner 8 with respect to the lugs along their axial direction. During driving, the vehicle body will continuously vibrate; the rubber liner 8, as an elastic damping layer, can reduce the transmission of vibrations and mitigate any resulting noise. Furthermore, during manufacturing and installation, as well as under stress and temperature changes, certain errors and deformations may occur. The elasticity of the rubber liner 8 can provide elastic compensation, compensating for tolerances and deformations, preventing abnormal loss or increase of internal stress or preload, and thus ensuring connection reliability.

[0059] In one embodiment, combined Figures 1 to 6 As shown, the fuel tank housing includes an upper housing 2 and a lower housing 1, and the lug 3 is formed by combining sub-lugs 31 located on the upper housing 2 and the lower housing 1 respectively.

[0060] Specifically, flanges are provided at the opening edges of the upper housing 2 and the lower housing 1. The upper housing 2 and the lower housing 1 are assembled together, and the two flanges are welded together to form a fuel chamber. The lug 31 can be integrally formed with the flange, or it can be separately fixedly connected to the flange.

[0061] In one embodiment, the fuel tank housing is provided with a limiting groove corresponding to the strap 4, and a portion of the strap 4 is located within the limiting groove.

[0062] The fuel tank strap assembly provided in this embodiment improves the stability of the strap 4 binding the fuel tank shell by setting a limiting groove, and avoids relative displacement between the strap 4 and the fuel tank shell along the width direction of the vehicle body.

[0063] Specifically, the limiting groove is formed by a recess in a local area of ​​the lower housing 1 corresponding to the strap 4.

[0064] In one embodiment, combined Figure 2 and Figure 3 As shown, a rubber pad 5 is provided between the strap 4 and the fuel tank housing.

[0065] The fuel tank strap assembly provided in this embodiment, by setting rubber pads 5, reduces the transmission of vibration, which helps to reduce the wear of the straps 4 on the fuel tank shell.

[0066] Specifically, the upper part of the fuel tank shell abuts against the vehicle body via a shock-absorbing pad, and the lower rubber pad 5 abuts against the strap 4, thereby reducing the transmission of vehicle body vibration to the fuel tank shell. This helps reduce fatigue damage to the fuel tank shell caused by vibration and avoids wear and abnormal noise caused by frictional contact between the strap 4 and the fuel tank shell. When a limit groove is provided on the fuel tank shell, at least a portion of the rubber pad 5 is located within the limit groove.

[0067] According to an embodiment of the present invention, another aspect provides a vehicle including the aforementioned fuel tank strap assembly.

[0068] Specifically, the fastener connects and fixes the first bend 41 and lug 3 of the strap 4 to the vehicle body, and the second bend 42 passes under the fuel tank shell and is connected and fixed to the part of the vehicle body corresponding to the other side of the fuel tank shell. The strap 4 abuts against the bottom surface of the fuel tank shell, and the top surface of the fuel tank shell is pressed against the vehicle body through the shock-absorbing pad. The first bend 41 and the second bend 42 are located on the front and rear sides of the fuel tank shell along the vehicle's direction of travel, respectively.

[0069] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
