[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] Example 1

[0048] As Figure 1-8 shown, it is an implementation scheme of the present utility model. A methanol fuel tank assembly made of stainless steel includes a fuel tank bracket 1 and a methanol fuel tank 2. The methanol fuel tank 2 is installed on the fuel tank bracket 1. The fuel tank bracket 1 is in an "L" shape. As Figure 3 shown, and a locking member is installed on the fuel tank bracket 1. The locking member is adapted to restrain the methanol fuel tank 2 on the fuel tank bracket 1. A fuel filling port 3 is respectively arranged on the upper part of the methanol fuel tank 2, and a drain bolt 4 is installed at the bottom. A tank breather valve 5 and a tank sensor mounting port 6 are installed on the top of the methanol fuel tank 2. The inner material of the methanol fuel tank 2 is stainless steel. The stainless steel material can reduce the reaction of methanol fuel and reduce the storage risk. Among them, the stainless steel can further be 304 stainless steel or 316L stainless steel.

[0049] The methanol fuel tank 2 includes a tank cylinder body 7. Tank end closures 8 are installed at both ends of the tank cylinder body 7. The tank end closures 8 close both ends of the tank cylinder body 7. An inner partition 9 is installed in the tank cylinder body 7. A plurality of flow holes are opened on the inner partition 9, and the flow holes facilitate the flow of fuel.

[0050] Protective leather pads 10 are arranged on both sides of the inner wall of the fuel tank bracket 1 opposite to the tank cylinder body 7. The protective leather pads 10 are movably abutted against the surface of the tank cylinder body 7. The protective leather pads increase the friction force of the installation contact surface and reduce the sliding of the methanol fuel tank.

[0051] The locking member includes a leather strap 11. A first connecting piece and a second connecting piece are respectively installed at both ends of the leather strap 11. The first connecting piece is hinged to the fuel tank bracket 1. The second connecting piece is connected to the fuel tank bracket 1. A first hinge port is installed at the upper end of the fuel tank bracket 1. The first connecting piece includes a connecting piece 12 and a first connecting shaft 13. The first connecting shaft 13 is installed at the end of the connecting piece 12. Symmetrical short cylinders 14 are installed in the first hinge port. Both ends of the first connecting shaft 13 are rotatably connected in two groups of short cylinders 14.

[0052] In this embodiment, by rotatably hinging one end of the cortical strap 11 to the fuel tank bracket 1 and achieving an adjustable closed connection at the other end, the methanol fuel tank can be fixed to the fuel tank bracket. In this embodiment, an elastic connector 15 and a first cylinder 16 are adopted. The elastic connector 15 is in a "Y" shape and is connected to the first cylinder 16. A first positioning hole is provided on the first cylinder 16, and a positioning bolt 17 is installed in the first positioning hole. A position opening is provided at the bottom end of the fuel tank bracket 1, and a long cylinder 18 is installed in the position opening. Both ends of the long cylinder 18 are fixedly installed in the position opening. A second positioning hole is provided on the long cylinder 18, and the second positioning hole is adapted to the first positioning hole. The positioning bolt 17 is suitable for connecting the first cylinder 16 and the long cylinder 18. By using the positioning bolt 17 to connect the first cylinder and the long cylinder, an adjustable connection effect can be achieved. The positioning holes provided on the first cylinder and the long cylinder are both threaded holes. During use, the long cylinder is fixed in the position opening and does not move. Rotate the first cylinder, align and connect the positioning bolt, and then the threaded connection can be completed.

[0053] Installation method: Place a fixed inner partition 9 inside the fuel tank cylinder body 7, then weld and clean the inner cavity surface. Then assemble the fuel tank heads on both sides and perform circumferential welding. Install the welding part's fuel filling port and the drain bolt 4 for installing the fuel tank. Then assemble the fuel tank breather valve 5, the fuel tank cap, and subsequently install the sensor at the fuel tank sensor installation port 6. Finally, assemble the fuel tank bracket on the outside of the vehicle frame, assemble the fuel tank protective padding on the bracket, and then place the fuel tank assembly in a fixed position. Connect the locking member to the fuel tank bracket with bolts. After installing it on the surface of the methanol fuel tank, lock it with the locking member.

[0054] Embodiment 2

[0055] As Figure 9 and 10 shown, in an implementation scheme of the present utility model, based on Embodiment 1, a slotted groove 19 is provided on the first cylinder 16, and the end of the elastic connector 15 is bonded in the slotted groove 19. There are two groups of fuel tank brackets 1, and the installation positions are at the 1 / 3 position of the methanol fuel tank 2, at a relatively balanced position. The slotted grooves 19 are symmetrically distributed for the installation of the elastic connector.

[0056] Embodiment 3

[0057] As Figure 11-14 shown, in another implementation scheme of the present utility model, based on Embodiment 1; a synchronous position member is installed at the bottom of the two groups of fuel tank brackets 1. One side of the synchronous position member is suitable for sleeving on the bottom of the positioning bolt 17 and is locked with a double nut 20. As Figure 13As shown in the figure, the synchronous positioning member includes a first plate member 21, and mounting holes are formed in the first plate member 21. A positioning screw 22 is installed and connected to the bottom of the fuel tank bracket 1; a fixing plate 23 is fixedly installed under the first plate member 21, and a diagonal pulling plate 24 is hingedly installed on the fixing plate 23. A sliding bar 25 is installed at one end of the diagonal pulling plate 24 away from the fixing plate 23. A sliding groove 26 is formed at the bottom of the first plate member 21, and the sliding bar 25 slides on the sliding groove 26;

[0058] A second plate member 27 is hingedly installed on the sliding bar 25. A through hole is formed in the second plate member 27 and sleeved on the positioning bolt 17, and double nuts 20 are installed on the positioning bolt 17. In actual installation, most methanol fuel tanks do not need to be disassembled. Glue is applied or direct welding is performed between the double nuts 20 to prevent the nuts from falling off due to vibration.

[0059] In this embodiment, the synchronous positioning member is adopted to install two sets of locking members. Since in Embodiment 1, the positioning bolt is threadedly connected to the first cylinder and the long cylinder, the threads will inevitably rotate during long-term use, resulting in the loosening of the fuel tank. Moreover, the body of the positioning bolt is necessarily inclined after installation, so it is difficult to fix it to the bottom of the fuel tank bracket through nuts. In this embodiment, the second plate member is installed at the bottom to achieve the effect of fixing and connecting two sets of locking members. The hinged connection between the first plate member and the second plate member on the sliding bar makes the installation position diverse and facilitates actual installation.

[0060] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

[0061] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only includes an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
