Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle fuel tanks, specifically to a fuel tank mounting structure. Background Technology

[0002] A motorcycle is a two- or three-wheeled vehicle powered by a gasoline engine, characterized by its lightness and maneuverability. It is widely used in transportation, logistics, racing, and recreation. Motorcycles are simple to operate, easy to learn, and relatively fast, making them very popular for urban commuting and short trips. Furthermore, motorcycles are fuel-efficient, saving more fuel than cars, and can easily navigate congested city roads.

[0003] According to Chinese Patent No. CN210761103U, a motorcycle fuel tank includes: an upper arched shell wall, which is in the shape of an arc arch, and the upper arched shell wall is provided with a fuel tank switch; a side shell wall, which has a transverse V-shaped protrusion on the side, and a groove is provided between the upper arched shell wall and the side shell wall; a frame mounting cavity, which has a U-shaped opening, the inner wall of the frame mounting cavity has a connecting structure, and the side shell wall has an edge connecting hole; the inner wall and bottom wall of the frame mounting cavity have mounting holes.

[0004] In the above solution, a connecting structure is used to fix the fuel tank to the frame, which still has the following disadvantages: Due to the rapid innovation and development of motorcycles, the models are also updated more frequently, so the fuel tank design is longer or larger than before. The mounting holes at the rear of the fuel tank cannot match the original mounting holes on the frame. Therefore, the frame needs to add adjustment mounting points, which increases the frame's condition and costs, makes quality control difficult, and increases installation difficulty. This makes it difficult for manufacturers to control costs and maintain consistent quality. Utility Model Content

[0005] The purpose of this utility model is to provide a fuel tank mounting structure to solve the problem that the mounting holes at the rear of the fuel tank cannot match the original mounting holes on the frame. Therefore, the frame needs to have additional mounting points for adjustment, which leads to an increase in the number of frame adjustments for manufacturers. This brings difficulties to manufacturers in terms of cost control and quality consistency.

[0006] A fuel tank mounting structure includes a front mounting lug base plate and a front mounting lug body, a mounting reinforcement plate, a rear mounting bracket, and a supporting reinforcement plate. The interior of the fuel tank is the fuel tank bottom, and the structure opposite to the interior is the fuel tank surface. The front mounting lug base plate and the supporting reinforcement plate are L-shaped. The front mounting lug base plate is welded to the fuel tank bottom by spot welding. Two mounting reinforcement plates located on the rear seat are spot welded to the fuel tank bottom. The fuel tank bottom and fuel tank surface are connected by roll welding to form a main body. The bottom of the front mounting lug body is welded to the front mounting lug base plate. The rear mounting bracket and the supporting reinforcement plate are welded to the two mounting reinforcement plates on the rear seat. The structure also includes a rear mounting aluminum component, the lateral cross-section of which is approximately a quarter circle, forming a multi-directional fixing component with a horizontally adapted fixing groove to the vehicle frame and a threaded groove in the arc direction. The supporting reinforcement plate is adapted to the arc direction of the rear mounting aluminum component.

[0007] Preferably, a fuel tank mounting structure includes a fuel tank base and a mounting plate. The fuel tank base is sealed at the bottom of the fuel tank body, and the mounting plate is disposed on the top surface of the vehicle frame. A fixing plate and a positioning plate are disposed on the top surface of the fuel tank base. A rear-mounted aluminum component for the fuel tank is detachably disposed on the top surface of the mounting plate. A fixing groove is formed on one side of the rear-mounted aluminum component, and a fixing bolt is rotatably inserted into the fixing groove. One end of the fixing bolt passes through the rear-mounted aluminum component and the mounting plate and is threaded with a nut. A support adhesive is disposed above the mounting plate. A bending plate is provided, and a Z-shaped plate is detachably provided on one side of the bending plate. The top surfaces of both the bending plate and the Z-shaped plate are in contact with the bottom surface of the fuel tank base. The fixing plate, fuel tank base, and support adhesive are fixed by bolts. Two adjustment holes are provided on the top surface of the support adhesive. The positioning plate, Z-shaped plate, and adjustment holes are fixed by bolts. Two fixing holes are provided on one side of the bending plate. Two through holes are provided on one side of the support adhesive. Two threaded grooves are provided on the side of the fuel tank where the aluminum part is installed at the rear. An adjustment bolt is rotatably inserted into the fixing hole. One end of the adjustment bolt passes through the through hole and is threadedly connected to the threaded groove.

[0008] Preferably, a limiting opening is provided on one side of the mounting plate, and a limiting strip is fixed on the frame, wherein the limiting opening and the limiting strip are slidably configured.

[0009] Preferably, the fuel tank base has hanging ears fixed on both sides of its interior, and the vehicle frame has fixing posts fixed on both sides of its interior. The fixing posts are covered with cushioning rubber before being assembled with the hanging ears.

[0010] Preferably, washers are slidably inserted into both the fixing bolt and the adjusting bolt.

[0011] Preferably, a buffer adhesive is provided between the supporting reinforcement plate and the arc surface of the aluminum component mounted at the rear of the oil tank.

[0012] Compared with existing technologies, the fuel tank installation structure that adopts the above technical solution has the following advantages:

[0013] 1. When installing the fuel tank onto the frame, the workers first weld the fixing plate and positioning plate to the top surface of the fuel tank base using spot welding. Then, the workers install and fix the mounting plate to the frame using bolts. Subsequently, the workers use bolts to fix the fixing plate, fuel tank base, and bending plate together. At the same time, the workers use fixing bolts to fix the rear mounting aluminum parts of the fuel tank to the mounting plate. Then, the support adhesive is installed on the rear mounting aluminum parts of the fuel tank. Finally, the support adhesive and bending plate are assembled together and fixed with adjusting bolts. This completes the installation and fixation of the fuel tank on the frame. By transferring the fixing point between the mounting plate set at the mounting point on the frame and the newly established mounting point on the fuel tank body, different styles of fuel tanks only require changes to the support adhesive and the rear mounting aluminum parts of the fuel tank. No other parts of the frame need to be changed, so that the frame can meet the universal requirements. This reduces the number of states the frame needs to change during the production process, thereby improving the production consistency of the product and achieving quality control.

[0014] Second, the rear-mounted aluminum component for the fuel tank has a lateral cross-section that approximates a quarter circle. It forms a multi-directional fixing component with a horizontally aligned mounting groove that matches the frame and an arc-shaped threaded groove. The supporting reinforcement plate adapts to the arc-shaped surface of the rear-mounted aluminum component, allowing it to be fixed to the frame via the horizontally aligned mounting groove. Simultaneously, the supporting reinforcement plate, also aligned with the arc-shaped surface of the rear-mounted aluminum component, secures the fuel tank to it. The presence of the rear-mounted aluminum component eliminates the need to alter the frame's shape to accommodate changes in the fuel tank's structure; a redesigned rear-mounted aluminum component with an adaptive structure serves as the transition and fixing component.

[0021] The following is a description of the first preferred embodiment of this utility model:

[0022] like Figure 1 As shown, the preferred embodiment of this utility model has the following design scheme for the fuel tank installation structure:

[0023] The fuel tank mounting structure includes a front mounting lug base plate 100 and a front mounting lug body 110, a mounting reinforcement plate 410, a rear mounting bracket 400, and a support reinforcement plate 420. The interior of the fuel tank is referred to as the fuel tank bottom 200, and the structure opposite to the interior is referred to as the fuel tank surface 300.

[0024] Specifically, the front hook base plate 100 is L-shaped, and the support reinforcement plate 420 is also L-shaped.

[0025] During installation:

[0026] First, the front mounting lug base plate 110 is welded to the fuel tank bottom 200 by spot welding;

[0027] Then, weld the two mounting reinforcement plates 410 on the rear seat to the bottom of the fuel tank 200.

[0028] The bottom 200 of the fuel tank and the surface 300 of the fuel tank are then connected and assembled into the main body by roll welding;

[0029] Next, the bottom of the left and right front ear body 110 is welded to the left and right front ear base plate 100;

[0030] Finally, the fuel tank rear mounting bracket 400 and the support reinforcement plate 420 are welded to the two mounting reinforcement plates 420 on the rear seat, and the main body of the fuel tank structure installation is completed.

[0031] The left and right front mounting lugs 100 mentioned above refer to the left and right sides that are relatively far from the rear of the vehicle and close to the front. In describing their position, the mounting lugs are referred to as the left and right front mounting lugs 100 to highlight their relative positional relationship.

[0032] The rear-mounted aluminum component 8 of the fuel tank has a lateral cross-section that is approximately a quarter circle. It forms a multi-directional fixing component with a horizontally aligned fixing groove 11 adapted to the frame and a curved surface with threaded grooves 17. The supporting reinforcement plate 420 is adapted to the curved surface of the rear-mounted aluminum component 8, allowing it to be fixed to the frame via the horizontally aligned fixing groove. Simultaneously, the supporting reinforcement plate 410, also adapted to the curved surface of the rear-mounted aluminum component, secures the fuel tank body 2 to the rear-mounted aluminum component 8. The presence of the rear-mounted aluminum component eliminates the need to alter the frame shape to accommodate changes in the fuel tank body 2; only the adaptable rear-mounted aluminum component 8 needs to be used as a transition fixing component.

[0033] The shape and structure of the aluminum component 8 mounted behind the fuel tank include, but are not limited to, a shape with a side cross-section that is approximately a quarter circle, as long as it does not require changes to the frame structure.

[0034] To enhance the buffering effect, a buffer rubber is provided between the support reinforcement plate and the arc surface of the aluminum component mounted at the rear of the fuel tank to absorb vibrations during driving.

[0035] In addition, the auxiliary support plate 430 can be used to abut against the support reinforcement plate 420.

[0036] Besides the fuel tank area, the frame installation also needs attention.

[0037] The design scheme for the fuel tank's installation structure in the vehicle is as follows: First, the rear-mounted aluminum component of the fuel tank is installed to the vehicle frame using bolts. (The rear-mounted aluminum component is one of the components that needs to be protected because it connects to the previous mounting point. The transfer and connection between itself and the newly established mounting point of the fuel tank is one of the conditions that this structural design scheme can achieve.)

[0038] After the front rubber sleeve of the fuel tank is fitted onto the front of the frame, the support rubber sleeve is then fitted onto the rear mounting aluminum part, and then the front mounting lug of the fuel tank body is fitted into the front rubber sleeve of the front of the frame. (The support rubber is also one of the contents protected by this patent, because the contact area between the support rubber and the fuel tank and aluminum parts is increased, thus reducing the transmission of vehicle vibration to the fuel tank).

[0039] Finally, fit the rear mounting bracket of the fuel tank into the designated holes on the support adhesive, and then secure the entire assembly with two bolts.

[0040] The components used in the fuel tank mounting structure are: fuel tank body 2, fuel tank front rubber sleeve, fuel tank rear mounting aluminum parts, fuel tank support rubber and vehicle frame 1.

[0041] The innovative features of the first preferred embodiment of this utility model are as follows:

[0042] 1) By transferring the fixed point through the newly established mounting point, and matching different styles of fuel tanks, only the support rubber and fuel tank need to be changed before installing the aluminum parts. No part of the frame needs to be changed, so that the frame can meet the universal conditions. The fuel tank mounting structure design method reduces the number of states of the frame during the production process. The aluminum parts can be installed after fastening the previous mounting point on the frame, and then the aluminum parts and fuel tank are connected, thereby improving the production consistency of the product and achieving quality control.

[0043] 2) The rear-mounted aluminum component and the support rubber are key innovative features for protection. The rear-mounted aluminum component connects the previous mounting points and transfers the fixing point through the newly established mounting point with the fuel tank. When using different types of fuel tanks, only the support rubber and the rear-mounted aluminum component of the fuel tank need to be changed. No other parts of the frame need to be changed. This is one of the conditions that this structural design can achieve.

[0044] 3) The support rubber is also a key innovation in protection. Because the contact area between the support rubber and the fuel tank and aluminum parts is increased, it has the advantage of reducing the transmission of vehicle vibration to the fuel tank.

[0045] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0046] like Figures 2-5 As shown, a fuel tank mounting structure includes a fuel tank base 3 and a mounting plate 4. The fuel tank base 3 is sealed at the bottom of the fuel tank body 2, and the mounting plate 4 is disposed on the top surface of the vehicle frame 1. The fuel tank base 3 has a fixing plate 5 and a positioning plate 6 on its top surface. A rear-mounted aluminum component 8 is detachably mounted on the top surface of the mounting plate 4. A fixing groove 11 is formed on one side of the rear-mounted aluminum component 8, and a fixing bolt 12 is rotatably inserted into the fixing groove 11. One end of the fixing bolt 12 passes through the rear-mounted aluminum component 8 and the mounting plate 4 and is threaded with a nut. A support rubber 9 is provided above the mounting plate 4, and a bending plate 7 is provided above the support rubber 9. A Z-shaped plate 10 is detachably mounted on one side of the bending plate 7. The top surfaces of the bent plate 7 and the Z-shaped plate 10 are both in contact with the bottom surface of the fuel tank base 3. The fixing plate 5, the fuel tank base 3 and the support rubber 9 are fixed by bolts. The top surface of the support rubber 9 has two adjustment holes 13. The positioning plate 6, the Z-shaped plate 10 and the adjustment holes 13 are fixed by bolts. The bent plate 7 has two fixing holes 15 on one side. The support rubber 9 has two through holes 16 on one side. The aluminum part 8 mounted on the rear of the fuel tank has two threaded grooves 17 on one side. The fixing hole 15 is rotatably inserted with an adjustment bolt 14. One end of the adjustment bolt 14 passes through the through hole 16 and is threadedly connected to the threaded groove 17. The mounting plate 4 has a limit port 18 on one side. The frame 1 is fixed with a limit strip 19. The limit port 18 and the limit strip 19 are slidably configured.

[0047] During use, when installing the fuel tank onto the frame 1, the workers first weld the fixing plate 5 and the positioning plate 6 to the top surface of the fuel tank base 3 using spot welding. Then, the workers install and fix the mounting plate 4 to the frame 1 using bolts. Subsequently, the workers use bolts to fix the fixing plate 5, the fuel tank base 3, and the bending plate 7 together. At the same time, the workers use fixing bolts 12 to fix the rear mounting aluminum part 8 of the fuel tank onto the mounting plate 4. Then, the support adhesive 9 is installed on the rear mounting aluminum part 8 of the fuel tank. Finally, the support adhesive 9 and the bending plate 7 are joined together and fixed using adjusting bolts 14. This completes the installation and fixation of the fuel tank on the frame 1. By transferring and connecting the mounting plate 4, which is set at the mounting point on the frame 1, with the newly established mounting point on the fuel tank body 2, the frame 1 can meet the universal conditions, reducing the number of states of the frame 1 during the production process, thereby improving the production consistency of the product and achieving quality control.

[0048] like Figure 3 and Figure 4 As shown, the fuel tank base 3 has two hanging ears 24 fixed on its inner sides, and the frame 1 has two fixing posts 25 fixed on its sides. The fixing posts 25 and the hanging ears 24 are slidably connected.

[0049] During use, when the staff fixes the fuel tank to the frame 1, they will first weld the fuel tank body 2 and the fuel tank base 3 together by spot welding. Then, when the fuel tank base 3 is installed on the frame 1, the staff will guide the fixing post 25 into the inside of the lug 24, which can initially fix the position of the fuel tank base 3 on the frame 1 and increase the stability of the fuel tank.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
