Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0049] In the following, in conjunction with the accompanying drawings, an auxiliary fuel tank provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0050] Embodiment 1:

[0051] like Figure 1 to Figure 2 As shown, an embodiment of the present application provides an auxiliary fuel tank, including a tank body 1, a fuel tank port 2, a mounting port 3, an oil outlet 4, a bracket 5, a fixing groove 6, and also includes a protection system 7 for protecting the tank body 1; a temperature control system 8 for controlling the oil temperature inside the tank body 1.

[0052] Furthermore, the protection system 7 includes a shell 71 , which is arranged on the bracket 5 ; a telescopic shock absorber 72 , which is arranged on the inner wall of the shell 71 ; and a shock absorbing layer 73 , which is used to provide shock absorbing protection for the box body 1 .

[0053] Furthermore, the telescopic shock absorber 72 includes a telescopic adjustment spring 721, which is respectively arranged on the outer shell 71 and the shock absorbing layer 73; a telescopic connecting plate 722, one end of which is close to the outer shell 71 and is movably connected to the telescopic adjustment spring 721; and a telescopic member 723, which is arranged on the telescopic connecting plate 722.

[0054] Furthermore, the telescopic member 723 is made of elastic material.

[0055] Furthermore, the protection system 7 also includes a limiting groove 74 , which is respectively arranged on the shell 71 and the shock-absorbing layer 73 ; and a protection pad 75 , which is arranged at the connection between the telescopic adjustment spring 721 and the telescopic connecting plate 722 .

[0056] Furthermore, the shock absorbing layer 73 further includes a first shock absorbing layer 731 , which is disposed in the box body 1 ; and a second shock absorbing layer 732 , which is disposed in the box body 1 .

[0057] In this embodiment of the present application, due to the adoption of the above structure, the fixing groove 6 and the bracket 5 firmly fix the box body 1 to the chassis of the car by bolts, and a mounting port 3 is provided on the box body 1. A sensor for detecting the amount of oil is installed inside the box body 1 by bolts at the mounting port 3. The box body 1 is composed of a first shock absorbing layer 731, a second shock absorbing layer 732, and a thermal insulation layer 88;

[0058] When the shell 71 is hit by an external object, a force will be generated on the shell 71 in the direction of the box body 1. Two telescopic shock absorbers 72 are provided at the bottom and side of the inner wall of the shell 71, so that the shell 71 can protect the box body 1 in all directions. The telescopic shock absorber 72 includes four telescopic adjustment springs 721, two cross-arranged telescopic connecting plates 722 and two telescopic members 723. The telescopic adjustment springs 721 are respectively arranged on the inner wall of the shell 71 and the limiting grooves 74 on the outer wall of the first shock absorbing layer 731. The middle positions of the two telescopic connecting plates 722 are movably connected by a movable shaft. The two ends of the telescopic connecting plate 722 are cross-connected with the telescopic adjustment springs 721 on the shell 71 and the first shock absorbing layer 731, respectively. A protective pad 75 is provided at the connection between the telescopic adjustment spring 721 and the telescopic connecting plate 722. The protective pad 75 is used to protect the telescopic adjustment spring 721 and extend its service life. The telescopic connecting plate 722 is provided with a mounting hole, and the telescopic member 723 is mounted on the telescopic connecting plate 722 through the mounting hole, and the mounting direction of the telescopic member 723 is parallel to the mounting direction of the telescopic adjusting spring 721. When the shell 71 is squeezed inwardly, the distance between the shell 71 and the first shock-absorbing layer 731 is shortened, so that the telescopic connecting plate 722 is squeezed toward the telescopic adjusting springs 721 at both ends. At this time, the telescopic adjusting spring 721 will generate an opposite force to push the telescopic connecting plate 722 so that the telescopic connecting plate 722 will return to its original position. During this squeezing process, the telescopic member 723 will stretch toward both ends. The telescopic member 724 is made of natural rubber, which has the characteristics of high elasticity, high tensile strength, and tear resistance. It can effectively absorb and disperse the impact energy of the shell 71, and cooperate with the telescopic adjusting spring 721 to achieve the shock-absorbing protection effect of the box body 1. The first shock-absorbing layer 731 and the second shock-absorbing layer 732 are also provided in the box body 1 to further enhance the shock-absorbing protection effect.

[0059] Embodiment 2:

[0060] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the temperature control system 8 includes a serpentine coil 81, which is arranged in the inner cavity of the box body 1; and a temperature sensor 82, which is arranged in the inner cavity of the box body 1.

[0061] Furthermore, the temperature control system 8 also includes a water heating box 83 , which is arranged on the bracket 5 ; and an electric heating rod 84 , which is arranged in the inner cavity of the water heating box 83 .

[0062] Furthermore, the temperature control system 8 also includes a water pumping pipeline 85, one end of which is connected to the water heating box 83, and the other end is connected to the serpentine coil 81; a return water pipeline 86, one end of which is connected to the water heating box 83, and the other end is connected to the serpentine coil 81; and a circulating pump 87, which is arranged on the water pumping pipeline 85.

[0063] Furthermore, the temperature control system 8 also includes a heat-insulating layer, which is arranged on the inner wall of the box body 1.

[0064] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the temperature sensor 82 detects that the oil temperature in the box body 1 is lower than the preset safety threshold, the water heating box 83 will automatically start the two electric heating rods 84 arranged inside, and the electric heating rods 84 can quickly heat the water in the water heating box 83, and the hot water inside the water heating box 83 will flow to the serpentine coil 81 through the circulation pump 87 arranged on the pumping pipe 85. The serpentine coil 81 can effectively increase the contact area between the serpentine coil 81 and the oil in the box body 1 through its serpentine structure, so that the heat exchange efficiency can be effectively improved and the flow performance of the oil can be guaranteed. After the heat exchange, the hot water will return to the water heating box 83 through the return pipe 86. An insulation layer 88 is also arranged on the inner wall of the box body 1, which can effectively isolate the influence of the external environment on the oil temperature inside the box body 1, and ensure that the oil temperature is stable and does not leak, thereby maintaining an ideal temperature control effect.
