Description

Technical Field

[0001] The utility model relates to the technical field of vehicle fuel tank installation, and in particular to a fuel tank installation structure. At the same time, the utility model also relates to a vehicle equipped with the fuel tank installation structure. Background Art

[0002] The capacity of a vehicle's fuel tank directly determines its range. For cars with identical engines, the larger the tank, the longer the range. With economic development, people's expectations for cars are becoming increasingly higher. To meet the demand for ultra-long driving range, car manufacturers are equipping vehicles with large fuel tanks. However, large fuel tanks require a lot of space and are difficult to arrange. Therefore, some models adopt a dual fuel tank design.

[0003] A dual fuel tank system typically consists of a main tank and a secondary tank. The secondary tank supplies fuel to the main tank via a secondary fuel pump and a first fuel supply pipe. The main tank, in turn, supplies fuel to the engine rail via a second fuel supply pipe, ensuring continuous and stable engine operation. The fuel supply pipes connect to the vehicle's fuel inlet, the main tank, and the secondary tank, respectively. A controller is connected to the secondary fuel pump to control it, pumping fuel from the secondary tank into the main tank.

[0004] In the prior art, the upper surface of the vehicle's main fuel tank is supported against the vehicle body or frame and fixed by straps. Adding an auxiliary fuel tank on this basis requires modifications to the vehicle body or frame, and a limiting structure for the fuel tank needs to be designed on the vehicle body, which results in a complex vehicle body structure and inconvenient processing. Utility Model Content

[0005] In view of this, the present invention aims to provide a fuel tank mounting structure to simplify the vehicle body structure and facilitate improved processing convenience.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A fuel tank mounting structure includes a support frame for mounting on a vehicle body, and a fuel tank clamp mounted on the support frame; the fuel tank clamp includes a detachably connected upper clamp and a lower clamp, and a clamping space for clamping the fuel tank is formed between the upper clamp and the lower clamp to enable the fuel tank to be fixed to the support frame.

[0008] Furthermore, the upper clamp is provided with a first reinforcing rib, the lower clamp is mounted on the support frame, and a reinforcing plate is provided at a portion of the lower clamp connected to the support frame.

[0009] Furthermore, the support frame is provided with an anti-slip portion, which is used to prevent the fuel tank from slipping out along the front-rear direction of the vehicle; and / or,

[0010] The support frame is provided with a limiting portion, which is used to limit the installation position of the oil tank on the support frame along the left-right direction of the entire vehicle.

[0011] Furthermore, there are multiple fuel tank clamps, and the multiple fuel tank clamps are arranged at intervals along the left-right direction of the vehicle; and / or, at least one of the support frame and the lower clamp is provided with a leakage hole.

[0012] Furthermore, the support frame includes a first beam and a second beam arranged at intervals along the front-to-rear direction of the vehicle, the first beam and the second beam both extend along the left-to-right direction of the vehicle, and both ends of the first beam and the second beam are used to connect to the vehicle body.

[0013] Furthermore, the support frame includes a first bracket and a second bracket; one end of the first beam and the second beam are connected to the vehicle body through the first bracket, and the other end of the first beam and the second beam are connected to the vehicle body through the second bracket.

[0014] Furthermore, a protective plate is provided at the lower portion of the support frame, and the protective plate is used to protect the lower portion of the oil tank.

[0015] Furthermore, the protective plate is provided with a second reinforcing rib; and / or the protective plate is provided with an opening.

[0016] Furthermore, the support frame and the fuel tank clamp are both provided with a vibration-damping part, and the support frame and the fuel tank clamp are in contact with the fuel tank through the vibration-damping parts thereon respectively.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The fuel tank mounting structure described in this utility model comprises a support frame, which is a foundational component mounted on the vehicle body. It provides a stable support platform for the fuel tank, ensuring that it can be stably and reliably mounted on the vehicle. The fuel tank clamp comprises an upper clamp and a lower clamp, which work together to tighten the fuel tank, making it easy to install and remove, greatly facilitating installation and maintenance. Furthermore, there is no need for a fuel tank retaining structure on the vehicle body; the fuel tank mounting structure alone can complete installation and retaining of the fuel tank, simplifying the vehicle body structure and making processing more convenient.

[0019] Secondly, the reinforcement ribs on the upper clamp can improve its bending strength and rigidity, so that the upper clamp can better withstand the pressure and vibration from the fuel tank when tightening the fuel tank. This not only ensures the stability of the fuel tank during installation, but also extends the service life of the upper clamp and reduces deformation or damage caused by long-term stress. The reinforcement plate can better increase the strength and rigidity of the connection part, so that it can better withstand the load from the fuel tank and the vehicle body, thereby improving the reliability and durability of the entire fuel tank installation structure, and preventing the fuel tank installation structure from causing the support frame to break or be damaged under long-term harsh working conditions.

[0020] Furthermore, the provision of an anti-slip portion ensures the stability and safety of the fuel tank during installation and use, effectively preventing it from falling out in the front-to-back direction of the vehicle, improving vehicle safety and providing the driver with a more reliable and secure driving experience. The provision of a position-limiting portion on the support frame limits the installation position of the fuel tank on the support frame in the left-to-right direction of the vehicle, effectively preventing the fuel tank from swaying in that direction and improving the stability and reliability of the fuel tank's fixation to the support frame.

[0021] Providing multiple fuel tank clamps is beneficial to improving the reliability of fuel tank fixation, and providing leakage holes on at least one of the support frame and the lower clamp, so that even if the fuel tank or oil pipe leaks or the vehicle wades through water, the oil and other liquids in these parts can be discharged in time and will not accumulate on the support frame or the lower clamp, thereby preventing these liquids from corroding or damaging the fuel tank and the support frame.

[0022] Furthermore, the support frame, comprised of a first beam and a second beam, works in conjunction with the aforementioned fuel tank clamp to form a stable frame structure that effectively supports and secures the fuel tank. The overall structure is simple and lightweight. These beams not only provide the required support area for the fuel tank but also ensure its stability in the left-right direction of the vehicle through their extension. They also absorb and disperse vibration and impact forces from the vehicle body to a certain extent, protecting the fuel tank from damage.

[0023] The connection between the first and second brackets forms a stable frame structure, providing sufficient support area and stability for the fuel tank. This connection also helps disperse and absorb vibration and impact from the vehicle body, protecting the fuel tank from damage. Furthermore, the first and second brackets share the same structure, making the fuel tank mounting structure easier to install on the vehicle body and ensuring secure and reliable tank attachment.

[0024] The protective plate effectively blocks stones, debris, and other sharp objects from the road, preventing them from directly impacting the lower surface of the fuel tank, thereby preventing damage or even leakage. If damaged, the protective plate can be replaced separately. Reinforcement ribs are also provided on the protective plate to provide greater rigidity and prevent excessive vibration during driving.

[0025] In some cases, fuel tanks require adequate ventilation and heat dissipation to prevent overheating. Openings in the fender ensure airflow and aid heat dissipation, reducing weight without compromising protective performance, thereby lowering the vehicle's curb weight and improving fuel economy. The openings prevent liquid from accumulating on the fender, thereby preventing damage. The openings also facilitate visibility of the tank's bottom markings, making it easier to view relevant information during vehicle certification.

[0026] The vibration damping parts installed on the support frame and the fuel tank clamp can effectively buffer the vibration and impact of the fuel tank during vehicle driving, improve its stability and service life, and better prevent collision and abnormal noise during vehicle driving.

[0027] Another object of the present invention is to provide a vehicle provided with the above-mentioned fuel tank mounting structure.

[0028] The vehicle described in the present invention has the same beneficial effects as the above-mentioned fuel tank mounting structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0047] Example 1

[0048] This embodiment relates to a fuel tank mounting structure, which can avoid designing a fuel tank limiting structure on the vehicle body, thereby helping to simplify the vehicle body structure and improve processing convenience.

[0049] In terms of overall structure, combined Figures 1 to 5 As shown in the figure, the fuel tank mounting structure of this embodiment includes a support frame 1 for mounting on the vehicle body, and a fuel tank clamp 2 mounted on the support frame 1. Here, the support frame 1 is a basic component mounted on the vehicle body, which can provide a stable support platform for the fuel tank 3, ensuring that the fuel tank 3 can be stably and reliably mounted on the vehicle.

[0050] The fuel tank clamp 2 includes a detachably connected upper clamp 21 and a lower clamp 22 , and a clamping space for clamping the fuel tank 3 is formed between the upper clamp 21 and the lower clamp 22 so as to fix the fuel tank 3 on the support frame 1 .

[0051] It can be understood that the fuel tank clamp 2 includes an upper clamp 21 and a lower clamp 22, which can cooperate to tighten the fuel tank 3, making it easy to assemble and disassemble the fuel tank 3, and can provide great convenience for the installation and maintenance of the fuel tank 3. There is no need to design a limiting structure for the fuel tank 3 on the vehicle body. The installation and limiting of the fuel tank 3 can be completed by the fuel tank installation structure alone. The vehicle body structure can be simplified and the processing is more convenient.

[0052] Furthermore, it is worth mentioning that Figure 1 and Figure 6 As shown, the fuel tank mounting structure in this embodiment can be used not only to fix gasoline tanks, but also to fix diesel tanks, and can match the layout of various vehicle models, thereby helping to improve the versatility of the fuel tank mounting structure and also helping to reduce production costs.

[0053] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 2As shown in the figure, the upper clamp 21 is provided with a first reinforcing rib 211, which can improve its bending strength and rigidity, so that the upper clamp 21 can better withstand the pressure and vibration from the fuel tank 3 when tightening the fuel tank 3. This not only ensures the stability of the fuel tank 3 during the installation process, but also extends the service life of the upper clamp 21 and reduces deformation or damage caused by long-term stress.

[0054] In the specific structure, the first reinforcing ribs 211 on each upper hoop 21 can be set to two and arranged at intervals along the left and right directions of the vehicle. Of course, the number of the first reinforcing ribs 211 can be designed and adjusted accordingly according to actual needs, for example, it can be set to one or three.

[0055] At the same time, the lower clamp 22 is mounted on the support frame 1, and a reinforcement plate 221 is provided at the connection between the lower clamp 22 and the support frame 1. It is understood that the reinforcement plate 221 mainly serves to strengthen the connection between the lower clamp 22 and the support frame 1. Since this connection is a key stress point in the fuel tank installation structure, it needs to be particularly strengthened to ensure the stability and safety of the fuel tank 3 installation.

[0056] The reinforcing plate 221 can effectively increase the strength and rigidity of the connection part, so that it can better withstand the load from the fuel tank 3 and the vehicle body, thereby improving the reliability and durability of the entire fuel tank mounting structure, and preventing the fuel tank mounting structure from causing the support frame 1 to break or be damaged under long-term harsh working conditions.

[0057] Furthermore, in this embodiment, as a preferred implementation form, Figure 3 As shown in FIG, support frame 1 is provided with an anti-slip portion 111, which is used to prevent the fuel tank 3 from being dislodged in the front-to-back direction of the vehicle. The provision of anti-slip portion 111 on support frame 1 ensures the stability and safety of the fuel tank 3 during installation and use. Anti-slip portion 111 effectively prevents the fuel tank 3 from being dislodged in the front-to-back direction of the vehicle, improving vehicle safety and providing a more reliable and secure driving experience for the driver.

[0058] In terms of specific structure, Figure 3 As shown, the anti-slip portion 111 is formed by bending a portion of the first beam body 11 forward and upward, so that the first beam body 11 can still be formed by bending a single tube, which helps to ensure its strength and rigidity, thereby improving its anti-slip reliability. It is also relatively easy to process and has low processing costs. It should be understood that in addition to being formed by bending a portion of the first beam body 11 forward and upward, the anti-slip portion 111 can also be separately processed and then fixed to the first beam body 11 by welding, screwing, etc.

[0059] It should be noted that Figure 3When the fuel tank mounting structure shown in FIG is applied to a vehicle, the anti-slip portion 111 is located at the front side of the fuel tank 3 and is mainly used to prevent the fuel tank 3 from slipping forward along the front-to-back direction of the vehicle.

[0060] It should be understood that in addition to providing the anti-slip portion 111 on the first beam body 11, the anti-slip portion 111 can of course also be provided on the second beam body 12 described below. The anti-slip portion 111 can be formed by bending a part of the second beam body 12 backward and upward, or it can be processed separately and then fixed to the second beam body 12 by welding, screwing, etc.

[0061] When this fuel tank mounting structure is used on a vehicle, anti-slip portions 111 are provided on both the front and rear sides of the fuel tank 3. The front anti-slip portion 111 is used to prevent the fuel tank 3 from slipping out forward along the front-rear direction of the vehicle, and the rear anti-slip portion 111 is used to prevent the fuel tank 3 from slipping out backward along the front-rear direction of the vehicle.

[0062] Furthermore, as a preferred embodiment, referring to Figure 3 As shown in , there are multiple fuel tank clamps 2, and the multiple fuel tank clamps 2 are arranged at intervals along the left and right directions of the vehicle. This arrangement is light in weight and helps to improve the reliability of fixing the fuel tank 3.

[0063] At the same time, if Figure 4 As shown in FIG, at least one of the support frame 1 and the lower clamp 22 is provided with a leakage hole 51. This arrangement has the advantage that even if the fuel tank 3 or the fuel pipe leaks or the vehicle wades through water, the oil and other liquids in these areas can be promptly drained away without accumulating in the support frame 1 or the lower clamp 22. In the specific structure, preferably, both the support frame 1 and the lower clamp 22 of this embodiment are provided with a leakage hole 51.

[0064] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown in the figure, the support frame 1 includes a first beam body 11 and a second beam body 12 arranged at intervals along the front-to-rear direction of the vehicle. The first beam body 11 and the second beam body 12 both extend along the left-right direction of the vehicle, and both ends of the first beam body 11 and the second beam body 12 are used to connect to the vehicle body.

[0065] Continue to refer to Figure 3 As shown, as a preferred embodiment, a limiting portion 112 is provided on the support frame 1, and the limiting portion 112 is used to limit the installation position of the fuel tank 3 on the support frame 1 along the left and right directions of the entire vehicle, so as to better prevent the fuel tank 1 from shaking along the left and right directions of the entire vehicle.

[0066] As in this embodiment, a limiting portion 112 is provided on both the first beam body 11 and the second beam body 12. The limiting portion 112 on the first beam body 11 specifically includes a bent portion where the left and right parts of the first beam body 11 are bent upward, and the limiting portion 112 on the second beam body 12 specifically includes a bent portion where the left and right parts of the second beam body 12 are bent upward.

[0067] The support frame 1 of such a structure, the first beam body 11 and the second beam body 12 are easy to process, and can better limit the installation position of the fuel tank 3 in the left and right directions, better prevent the fuel tank 3 from shaking along the left and right directions of the entire vehicle, and help improve the reliability of the installation and fixation of the fuel tank 3 on the support frame 1.

[0068] It should be understood that the limiting portion 112 in this embodiment can be formed by bending the first beam body 11 and the second beam body 12, and can also be processed separately and then fixed to the first beam body 11 and the second beam body 12 by welding, screwing, etc.

[0069] Here, it can be understood that the support frame 1 is composed of a first beam body 11 and a second beam body 12, and they are arranged at intervals along the front and rear direction of the vehicle, and both extend along the left and right direction of the vehicle. Together with the aforementioned fuel tank clamp 2, a stable frame structure can be formed, which can effectively support and fix the fuel tank 3, and the overall structure is simple and light in weight.

[0070] Furthermore, as the primary components of the support frame 1, the first and second beams 11, 12 not only provide the required support area for the fuel tank 3 but also, through their extension, ensure the stability of the fuel tank 3 in the left-right direction of the vehicle. Furthermore, because the first and second beams 11, 12 are spaced apart along the front-to-back direction of the vehicle, they can absorb and disperse vibration and impact forces from the vehicle body to a certain extent, thereby protecting the fuel tank 3 from damage.

[0071] It should be noted that the first beam 11 and the second beam 12 in this embodiment can be made of tubular beams, which only need to be bent and stamped without the need for mold making, which is conducive to cost saving. Specifically, in this embodiment, as a preferred implementation form, Figure 3 As shown, the support frame 1 includes a first bracket 13 and a second bracket 14 , wherein one end of the first beam 11 and the second beam 12 are connected to the vehicle body through the first bracket 13 , and the other end of the first beam 11 and the second beam 12 are connected to the vehicle body through the second bracket 14 .

[0072] Here, through the connection of the first bracket 13 and the second bracket 14, the first beam 11 and the second beam 12 form a stable frame structure, providing sufficient support area and stability for the fuel tank 3. This connection also helps to disperse and absorb vibration and impact from the vehicle body, thereby protecting the fuel tank 3 from damage. Furthermore, the first and second beams 11 and 12 share the first bracket 13 and the second bracket 14, making the fuel tank mounting structure easy to install on the vehicle body and ensuring the safe and reliable fixing of the fuel tank 3.

[0073] It is worth mentioning that the first bracket 13 and the first beam 11, the first bracket 13 and the second beam 12, the second bracket 14 and the first beam 11, and the second bracket 14 and the second beam 12 are all detachably connected. In addition, the structures of the first bracket 13 and the second bracket 14 can be modified as needed to achieve compatibility with different vehicle models.

[0074] At the same time, in this embodiment, as a preferred implementation form, Figure 1 As shown in FIG, a protective plate 4 is provided at the lower portion of the support frame 1 to protect the lower portion of the fuel tank 3. Thus, the protective plate 4 effectively blocks stones, debris, or other sharp objects on the road, preventing them from directly impacting the lower surface of the fuel tank 3, thereby preventing damage or even leakage to the fuel tank 3. Furthermore, the protective plate 4 can be replaced separately if damaged.

[0075] It is worth mentioning that the protective plate 4 of this embodiment is detachably connected to the support frame 1, so that maintenance personnel can easily remove the protective plate 4 to inspect, repair or replace the lower surface of the oil tank 3, which can greatly reduce the difficulty and cost of maintenance.

[0076] In the specific structure, projection weld studs are provided on the support frame 1 and cooperate with nuts to secure the protective plate 4. It should be noted that the projection weld studs need to be partially avoided on the fuel tank 3 to prevent interference between the projection weld studs and the fuel tank 3. In practice, the protective plate 4 is screwed to the bottom of the support frame 1, allowing the entire plate to be lifted during assembly, saving vehicle assembly time.

[0077] In this embodiment, as a preferred implementation form, Figure 5 As shown, the protective plate 4 is provided with a second reinforcing rib 41 , thereby making the entire protective plate 4 have better rigidity and preventing the protective plate 4 from vibrating excessively during driving.

[0078] At the same time, in some cases, the fuel tank 3 requires good ventilation and heat dissipation conditions to prevent overheating. To meet the heat dissipation requirements of the fuel tank 3, the protective plate 4 of this embodiment is provided with openings 42. This arrangement ensures air circulation, helps dissipate heat from the fuel tank 3, and reduces its weight without affecting its protective performance, thereby reducing the vehicle's curb weight and improving fuel economy.

[0079] In addition, the openings 42 prevent liquid from accumulating on the protective plate 4, thereby preventing damage to the protective plate 4. Furthermore, to facilitate viewing of the markings on the bottom of the fuel tank 3 and relevant information about the fuel tank 3 during vehicle certification, three larger openings 42 are provided at locations corresponding to the markings on the fuel tank 3.

[0080] In addition, in this embodiment, as a preferred implementation form, Figure 3 、 Figure 4 and Figure 5 As shown in , the support frame 1 and the fuel tank clamp 2 are both provided with a vibration damping part, and the support frame 1 and the fuel tank clamp 2 are in contact with the fuel tank 3 through the vibration damping parts thereon.

[0081] Here, by setting the vibration-damping part on the support frame 1 and the fuel tank clamp 2, the vibration and impact received by the fuel tank 3 during the driving of the vehicle can be effectively buffered, thereby improving its stability and service life, and better preventing abnormal noise due to collision during the driving of the vehicle.

[0082] It should be noted that the vibration damping components in this embodiment are made of a rubber-like material that can reduce impact. Preferably, the support frame 1 in this embodiment includes the aforementioned protective plate 4. Therefore, in the specific structure, the first beam 11 and the second beam 12 are provided with a first vibration damping component 15, and the first beam 11 and the second beam 12 are in contact with the fuel tank 3 via the first vibration damping component 15. The upper clamp 21 is provided with a second vibration damping component 212, and the upper clamp 21 is in contact with the fuel tank 3 via the second vibration damping component 212. The protective plate 4 is provided with a third vibration damping component 43, and the protective plate 4 is in contact with the fuel tank 3 via the third vibration damping component 43.

[0083] In addition, in other implementations, the lower clamp 22 in this embodiment may also be provided with a vibration-damping portion, and the lower clamp 22 is in contact with the oil tank 3 through the vibration-damping portion thereon.

[0084] When the fuel tank mounting structure of this embodiment is in use, the lower side of the fuel tank 3 adopts a support frame 1, and the upper side is fastened in the form of a double fuel tank clamp 2. The fuel tank 3 is fixed to the support frame 1 by the two fuel tank clamps 2. In this way, there is no need for the fuel tank 3 to support the vehicle body or for the frame to cooperate with the vehicle body. The limited installation of the fuel tank 3 can be completed by relying solely on the fuel tank mounting structure.

[0085] Finally, it should be noted that Figure 2As shown, on the oil tank 3 of this embodiment, a clamping groove 31 is provided at the position that cooperates with the first beam body 11, the second beam body 12 and the oil tank clamp 2. In the clamping groove 31, the matching position of the first beam body 11 and the lower clamp 22, as well as the matching position of the second beam body 12 and the lower clamp 22 are provided with a clamping ring 32. The clamping ring 32 is processed into a semicircular shape by a thin plate, and the clamping ring 32 is interference fit in the clamping groove 31 on the oil tank 3, so that the oil tank 3 can be fixed more firmly on the first beam body 11 and the second beam body 12 of the support frame 1.

[0086] In addition, when the vehicle body (frame) and surrounding parts undergo large modifications and the cost is high due to the addition of an auxiliary fuel tank, the fuel tank mounting structure can be applied. Moreover, the fuel tank mounting structure can also simultaneously meet the installation requirements of both diesel and gasoline tanks, and can match the layout environments of various vehicle models. It can improve the versatility of the fuel tank 3 and the fuel tank mounting structure, and help reduce the cost of the entire vehicle.

[0087] Example 2

[0088] This embodiment relates to a vehicle, in which a fuel tank 3 is mounted on the vehicle body via the fuel tank mounting structure of the first embodiment.

[0089] The vehicle of this embodiment adopts the fuel tank mounting structure in Example 1, which facilitates the installation of the fuel tank 3 through the support frame 1 and the fuel tank clamp 2. At the same time, there is no need to design a fuel tank limiting structure on the vehicle body. The fuel tank 3 can be installed and limited only by the fuel tank mounting structure in Example 1, which can simplify the vehicle body structure and help improve the convenience of processing.

[0090] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
