[0003] However, for hybrid electric vehicles with long range and long mileage, a large-capacity power battery is usually required. The large capacity power battery is also relatively large, which can easily lead to interference problems between the power battery and the fuel tank in the process assembly.

[0009] Optionally, the fuel tank mounting structure further includes a second bracket, which is located below the first bracket and is used to connect to the lower end of the crossbeam. The second bracket and the mounting part are respectively provided with a first mounting hole and a second mounting hole, which are coaxially arranged and used to install the fuel tank strap.

[0010] Optionally, the second bracket includes a first plate body and a first flange structure. The first mounting hole is provided on the first plate body, and the first flange structure is provided at both ends of the first plate body in the left-right direction of the vehicle.

At the same time, the mounting part of the first bracket is used to connect with the fuel tank strap to provide a mounting point for the fuel tank. Moreover, by designing the mounting part to extend away from the connecting part along the front-rear direction of the vehicle, when the first bracket is assembled on the side of the crossbeam away from the power battery, the mounting part can be moved away from the power battery, thereby making the mounting position of the fuel tank as far away from the power battery as possible. This not only avoids interference between the power battery and the fuel tank during assembly, but also provides more assembly space for the power battery, so that the mounting position of the fuel tank can be adapted to accommodate power batteries of different capacities.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] In the attached figures, the Z-axis represents the vertical direction, i.e., the up-down position, with the positive direction of the Z-axis (i.e., the direction the arrow points) representing upwards and the negative direction representing downwards. The X-axis represents the horizontal direction and is designated as the left-right position, with the positive direction of the X-axis representing the right side and the negative direction representing the left side. The Y-axis represents the front-back position, with the positive direction of the Y-axis representing the front side and the negative direction representing the back side. It should be noted that the aforementioned representations of the Z-axis, Y-axis, and X-axis are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0031] In existing technologies, the power battery and fuel tank of hybrid electric vehicles are typically mounted on the rear of the vehicle using a suspended configuration. The fuel tank mounting point is usually located at the bottom end of a crossbeam 400 at the rear of the vehicle. When a hybrid electric vehicle is equipped with a large-capacity power battery, the large-capacity battery may occupy part of the fuel tank's mounting space, causing interference between the fuel tank and the power battery in the vertical direction of the vehicle, thus preventing the fuel tank from being installed. This invention addresses this by designing a fuel tank mounting structure that moves the fuel tank mounting point forward (when the power battery is located at the rear of the fuel tank) or backward (when the power battery is located at the front of the fuel tank), thus avoiding interference between the power battery and the fuel tank during assembly. It also provides more assembly space for the power battery, allowing the fuel tank mounting position to accommodate power batteries of different capacities.

[0032] Combination Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a fuel tank mounting structure, including a first bracket 1. The first bracket 1 includes a connecting part 11 and a mounting part 12. The connecting part 11 is used to connect to the front or rear side of the vehicle's crossbeam 400. The mounting part 12 is connected to the connecting part 11 and is used to extend away from the connecting part 11 along the front-rear direction of the vehicle. The mounting part 12 is also used to connect to the vehicle's fuel tank strap.

[0033] It should be noted that the vehicle's forward and backward direction is... Figure 1 In the Y-axis direction, correspondingly, the vehicle's left and right directions are... Figure 1 In the X-axis direction, the vertical direction of the vehicle is... Figure 1 In the Z-axis direction.

[0034] Specifically, such as Figure 1 As shown, since two fuel tank straps are usually attached to the fuel tank, two sets of fuel tank mounting structures are typically used to connect to these two straps respectively. The first bracket 1 is the main support structure of the fuel tank mounting structure. When the power battery and fuel tank are respectively arranged on the rear and front sides of the crossbeam 400, the first bracket 1 is used to mount on the front side of the crossbeam 400; when the power battery and fuel tank are respectively arranged on the front and rear sides of the crossbeam 400, the first bracket 1 is used to mount on the rear side of the crossbeam 400. Figure 1 An example is given of a first bracket 1 installed on the rear side of a crossbeam 400. The first bracket 1 includes a connecting part 11 and a mounting part 12. The connecting part 11 and the mounting part 12 are usually integrally connected and together form an L-shaped structure or a similar L-shaped structure. The connecting part 11 constitutes the vertical part of the L-shaped structure and is usually fixed to the front or rear side of the crossbeam 400 by bolt connection. The mounting part 12 constitutes the horizontal part of the L-shaped structure and is used to connect to the fuel tank strap tied to the fuel tank by a detachable method such as bolt connection.

[0035] In this embodiment, the fuel tank mounting structure can achieve the connection between the first bracket 1 and the crossbeam 400 located at the rear of the vehicle by setting a first bracket 1 and connecting the connecting part 11 of the first bracket 1 to the front or rear side of the crossbeam 400 located at the rear of the vehicle. At the same time, the mounting part 12 of the first bracket 1 is used to connect with the fuel tank strap to provide a mounting point for the fuel tank. Moreover, by designing the mounting part 12 to extend away from the connecting part 11 along the front-rear direction of the vehicle, when the first bracket 1 is assembled on the side of the crossbeam 400 away from the power battery, the mounting part 12 can be moved away from the power battery, thereby making the mounting position of the fuel tank as far away from the power battery as possible. This not only avoids interference between the power battery and the fuel tank during assembly, but also provides more assembly space for the power battery, so that the mounting position of the fuel tank can be adapted to accommodate power batteries of different capacities.

[0036] Optionally, combined Figure 4 As shown, the connecting part 11 includes a first bent section 111, a second bent section 112 and a reinforcing rib 113. The first bent section 111 is used to fit against the crossbeam 400. The two ends of the second bent section 112 are connected to the first bent section 111 and the mounting part 12 respectively. The reinforcing rib 113 extends from the first bent section 111 to the second bent section 112.

[0037] In this embodiment, the connecting portion 11 has a bent structure and includes multiple bent segments. These multiple bent segments are formed by bending the connecting portion 11 once or multiple times, so that the connecting portion 11 has one or more bent locations. Figure 4The diagram illustrates an example where the connecting portion 11 is bent once to form a first bent segment 111 and a second bent segment 112. By configuring the connecting portion 11 as a bent structure including the first bent segment 111 and the second bent segment 112, the structural strength of the connecting portion 11 and even the first support 1 is enhanced. Furthermore, a reinforcing rib 113 is provided on two adjacent bent segments and passes through the connection point between these two adjacent bent segments, i.e., the reinforcing rib 113 passes through the bent portion of the connecting portion 11. Thus, the reinforcing rib 113 can be used to further enhance the structural strength of the bent portion of the connecting portion 11, thereby suppressing deformation of the first support 1.

[0038] Optionally, combined Figure 3 As shown, the first bracket 1 also includes a first fixing part 13 connected to the connecting part 11. The first fixing part 13 is located on one side of the connecting part 11 in the left-right direction of the vehicle and is used to fix the wiring harness.

[0039] In this embodiment, the first fixing part 13 is located on the left or right side of the connecting part 11, and the first fixing part 13 is usually provided with a first fixing hole 131. The first fixing hole 131 is used to fix the wiring harness of electrical components such as an integrated vehicle power management module (hereinafter referred to as ODP). This arrangement allows the first bracket 1 to be used to install the fuel tank and to fix the wiring harness of electrical components such as ODP, thus expanding the functionality of the fuel tank mounting structure.

[0040] Optionally, combined Figure 3 As shown, the first bracket 1 also includes a reinforcing part 14, which is located on the same side of the connecting part 11 as the first fixing part 13, and the reinforcing part 14 is connected to the connecting part 11 and the mounting part 12 respectively.

[0041] In this embodiment, when the first fixing part 13 is located on the left side of the connecting part 11, the reinforcing part 14 is also located on the left side of the connecting part 11; when the first fixing part 13 is located on the right side of the connecting part 11, the reinforcing part 14 is also located on the right side of the connecting part 11. Regardless of whether the reinforcing part 14 is located on the left or right side of the connecting part 11, the reinforcing part 14 is connected to both the connecting part 11 and the mounting part 12. Thus, by adding a reinforcing part 14 to the side of the connecting part 11 where the first fixing part 13 is located, not only can the structural strength of the first bracket 1 be further improved, but sufficient rigidity and strength mounting points can also be provided for electrical components such as ODP harnesses.

[0042] Furthermore, the reinforcing part 14 is typically a triangular support structure. This gives the reinforcing part 14 high stability and support, while also providing sufficient rigidity and strength to the first fixing part 13 and reinforcing the connection part 11 and mounting part 12.

[0043] Furthermore, when there are two sets of fuel tank mounting structures, a first fixing part 13 can be provided on the first bracket 1 of one set of fuel tank mounting structures, while the first fixing part 13 is not provided on the first bracket 1 of the other set of fuel tank mounting structures, such as... Figure 1 As shown; alternatively, a first fixing part 13 can be set on the first bracket 1 of both sets of oil tank mounting structures. In practical applications, the setting can be selected according to the wiring needs.

[0044] Furthermore, combined Figure 3 As shown, the first bracket 1 also includes a second fixing part 15. The second fixing part 15 and the first fixing part 13 are respectively located on both sides of the connecting part 11 in the left-right direction of the vehicle. The second fixing part 15 is connected to the mounting part 12 and is used to fix it to the tube bundle.

[0045] In this embodiment, the second fixing part 15 and the first fixing part 13 are located on the left and right sides of the connecting part 11, respectively. When the fuel tank mounting structure has two sets, the second fixing parts 15 in the two first brackets 1 can be located on the same side of the connecting part 11, or they can be arranged symmetrically on the left and right sides, such as... Figure 1 As shown. Additionally, the second fixing part 15 is typically provided with a second fixing hole 151, which is used to fix tubing such as air conditioning pipes. This arrangement allows the first bracket 1 to be used to fix both wiring harnesses for electrical components such as ODPs and tubing such as air conditioning pipes, further expanding the functionality of the fuel tank mounting structure.

[0046] Optionally, combined Figure 3 , Figure 5 and Figure 6 As shown, the fuel tank mounting structure also includes a second bracket 2, which is located below the first bracket 1 and is used to connect to the lower end of the crossbeam 400. The second bracket 2 and the mounting part 12 are respectively provided with a first mounting hole 211 and a second mounting hole 121. The first mounting hole 211 and the second mounting hole 121 are coaxially arranged and used to install the fuel tank strap.

[0047] Specifically, the second bracket 2 is usually plate-shaped and extends in the front-to-back direction. Part of its structure is located directly below the crossbeam 400 and is spot-welded to the lower end of the crossbeam 400. The other part of its structure is located directly below the mounting part 12 of the first bracket 1 and is provided with a first mounting hole 211. At the same time, a second mounting hole 121 is provided on the mounting part 12 at a position corresponding to the first mounting hole 211.

[0048] In this way, when assembling the fuel tank, fasteners such as bolts can be inserted into the first mounting hole 211, the second mounting hole 121, and the mounting holes on the fuel tank strap to mount the fuel tank on the first bracket 1 and the second bracket 2. This allows the second bracket 2 to drag the fuel tank mounting point from the lower part of the first bracket 1, thereby transferring the force to the crossbeam 400. This further improves the rigidity and strength of the fuel tank mounting point, ensuring that the fuel tank mounting structure can meet the strength and rigidity requirements during fuel tank suspension installation, and thus ensuring the normal operation of the fuel tank during vehicle operation.

[0049] Optionally, combined Figure 5 and Figure 6 As shown, the second bracket 2 includes a first plate body 21 and a first flange structure 22. A first mounting hole 211 is provided on the first plate body 21. The first flange structure 22 is provided at both ends of the first plate body 21 in the left-right direction of the vehicle, and the first flange structure 22 is used to be provided on the side of the first plate body 21 away from the crossbeam 400.

[0050] In this embodiment, by setting first flange structures 22 on the left and right sides of the first plate body 21, the second support 2 is made into a plate structure with a U-shaped cross-section. Compared with the flat plate structure, the U-shaped plate structure has higher strength and rigidity, which can further improve the strength and rigidity of the second support 2 and even the fuel tank mounting point. Moreover, by setting the first flange structure 22 on the side of the first plate body 21 away from the crossbeam 400, on the one hand, it can prevent the first flange structure 22 from interfering with the crossbeam 400, and on the other hand, it can ensure that the first plate body 21 can fit tightly with the lower end of the crossbeam 400, increasing the connection area.

[0051] Optionally, combined Figure 2 and Figure 7 As shown, the fuel tank mounting structure also includes a reinforcing plate 3, which is disposed in the cavity of the crossbeam 400 and is used to connect to the connecting part 11 through the crossbeam 400.

[0052] In this embodiment, the crossbeam 400 is typically a hollow structure with a cavity. The first support 1 is located outside the crossbeam 400 and is connected to the outer front or outer rear end of the crossbeam 400. The reinforcing plate 3 is located inside the cavity of the crossbeam 400 and is connected to the inner front or inner rear end of the crossbeam 400. This allows the reinforcing plate 3 to be connected to the connecting part 11 via the crossbeam 400. Furthermore, based on the first support 1, or based on the first support 1 and the second support 2, the reinforcing plate 3 can be used to further support the first support 1 under stress, thereby further enhancing the rigidity and strength of the fuel tank mounting point.

[0053] Furthermore, combined Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the connecting part 11 is provided with a first connecting hole 114, the reinforcing plate 3 is provided with a second connecting hole 311, and the crossbeam 400 is provided with a third connecting hole 421. The first connecting hole 114 and the second connecting hole 311 are respectively used to be coaxially arranged with the third connecting hole 421.

[0054] In this embodiment, since the reinforcing plate 3 is located inside the cavity of the crossbeam 400, a nut is usually pre-embedded in the second connecting hole 311 on the reinforcing plate 3 to facilitate the bolt connection between the connecting part 11, the reinforcing plate 3, and the crossbeam 400. When assembling the reinforcing plate 3 and the first bracket 1, fasteners such as bolts can be sequentially inserted into the first connecting hole 114, the third connecting hole 421, and the second connecting hole 311 to fix the first bracket 1, the reinforcing plate 3, and the crossbeam 400 together. This not only saves on the number of fasteners used but also makes the operation simple and convenient, and improves the efficiency of assembly and disassembly.

[0055] Optionally, combined Figure 2 , Figure 7 and Figure 8 As shown, the reinforcing plate 3 includes a second plate body 31 and a second flange structure 32. The second flange structure 32 is located on the side of the second plate body 31 away from the first bracket 1. The crossbeam 400 includes a first crossbeam plate 410 and a second crossbeam plate 420 that form a cavity. The second flange structure 32 is used to connect with the first crossbeam plate 410. The second plate body 31 and the connecting part 11 are respectively used to connect with the second crossbeam plate 420 on both sides in the front-rear direction of the vehicle.

[0056] Specifically, the second flange structure 32 can be disposed on the left and / or right side of the second plate body 31, or it can be disposed around the edge of the second plate body 31. Figure 8 An example is given in which the second flange structure 32 is set on the left and right sides of the second plate body 31. When the power battery and the fuel tank are respectively arranged on the front and rear sides of the crossbeam 400, the first crossbeam plate 410 is the front crossbeam plate of the crossbeam 400, and the second crossbeam plate 420 is the rear crossbeam plate of the crossbeam 400. At this time, the connecting part 11 of the first bracket 1 and the second plate body 31 of the reinforcing plate 3 are respectively connected to the rear side and the front side of the rear crossbeam plate of the crossbeam 400, while the second flange structure 32 of the reinforcing plate 3 is connected to the front crossbeam plate of the crossbeam 400. When the power battery and the fuel tank are respectively arranged on the rear and front sides of the crossbeam 400, the first crossbeam plate 410 is the rear crossbeam plate of the crossbeam 400, and the second crossbeam plate 420 is the front crossbeam plate of the crossbeam 400. At this time, the connecting part 11 of the first bracket 1 and the second plate body 31 of the reinforcing plate 3 are respectively connected to the front side and the rear side of the front crossbeam plate of the crossbeam 400, while the second flange structure 32 of the reinforcing plate 3 is connected to the rear crossbeam plate of the crossbeam 400.

[0057] In this embodiment, a second flange structure 32 is provided on the side of the second plate body 31 away from the first support 1 to improve the strength and rigidity of the reinforcing plate 3. At the same time, by connecting the second plate body 31 to the second crossbeam plate 420 of the crossbeam 400 and connecting the second flange structure 32 to the first crossbeam plate 410 of the crossbeam 400, the stress and deformation of the crossbeam 400 are improved, so that the vertical surface of the crossbeam 400 has sufficient rigidity to support the stress of the first support 1, thereby further strengthening the rigidity and strength performance of the fuel tank mounting point.

[0058] Optionally, combined Figures 6 to 8 As shown, the second bracket 2 is provided with a fourth connecting hole 212, the second plate body 31 is provided with a fifth connecting hole 312, and the second crossbeam plate 420 is provided with a sixth connecting hole. The fourth connecting hole 212 and the fifth connecting hole 312 are respectively used to be coaxially set with the sixth connecting hole.

[0059] Specifically, the second bracket 2 is usually welded to the lower end of the second crossbeam plate 420, the lower end of the second plate body 31 is attached to the lower end of the second crossbeam plate 420, the fourth connecting hole 212 is provided on the first plate body 21 of the second bracket 2 and is located directly below the crossbeam 400, the fifth connecting hole 312 is provided at the lower end of the second plate body 31, and the sixth connecting hole on the second crossbeam plate 420 is usually the original oil tank mounting hole on the crossbeam 400.

[0060] In this way, when assembling the reinforcing plate 3 and the second bracket 2 onto the crossbeam 400, fasteners such as bolts can be sequentially inserted into the fourth connecting hole 212, the sixth connecting hole, and the fifth connecting hole 312 to fix the second bracket 2, the reinforcing plate 3, and the crossbeam 400 together. This not only saves on the number of fasteners used but also simplifies the operation, making assembly and disassembly efficient. Furthermore, the fourth connecting hole 212 allows the second bracket 2 to be connected to the oil tank mounting hole (i.e., the sixth connecting hole) at the lower end of the second crossbeam plate 420 using bolts or other fasteners before welding it onto the crossbeam 400. This secures the second bracket 2 to the crossbeam 400, achieving pre-positioning, before spot welding, thus improving the convenience of welding.

[0061] Optionally, combined Figure 7 and Figure 8 As shown, the reinforcing plate 3 also includes a third flange structure 33, which is used at the connection between the first crossbeam plate 410 and the second crossbeam plate 420.

[0062] In this embodiment, the third flange structure 33 is disposed at the lower end of the second plate body 31 and is used to clamp between the lower ends of the first crossbeam plate 410 and the lower ends of the second crossbeam plate 420. In this way, on the one hand, the third flange structure 33 can be used to further improve the strength and rigidity of the reinforcing plate 3; on the other hand, the first crossbeam plate 410 and the second crossbeam plate 420 can be used to clamp and fix the edge of the reinforcing plate 3, ensuring the firmness of the connection between the reinforcing plate 3 and the crossbeam 400.

[0063] Another embodiment of the present invention provides a vehicle including the fuel tank mounting structure described above.

[0064] The vehicle in this embodiment includes a power battery, a fuel tank, a crossbeam 400, and the aforementioned fuel tank mounting structure. The crossbeam 400 includes a first crossbeam plate 410 and a second crossbeam plate 420 that enclose a cavity. When the power battery and the fuel tank are respectively arranged on the front and rear sides of the crossbeam 400, the first crossbeam plate 410 is the front crossbeam plate of the crossbeam 400, and the second crossbeam plate 420 is the rear crossbeam plate of the crossbeam 400. In this case, the first bracket 1 of the fuel tank mounting structure is connected to the rear side of the rear crossbeam plate of the crossbeam 400. When the power battery and the fuel tank are respectively arranged on the rear and front sides of the crossbeam 400, the first crossbeam plate 410 is the rear crossbeam plate of the crossbeam 400, and the second crossbeam plate 420 is the front crossbeam plate of the crossbeam 400. In this case, the first bracket 1 is connected to the front side of the front crossbeam plate of the crossbeam 400. Furthermore, the beneficial effects of the vehicle in this embodiment compared to the prior art are the same as those of the aforementioned fuel tank mounting structure, and will not be repeated here.

[0065] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
