DETAILED DESCRIPTION

[0027] The features and performances of the present application are described in further detail below in combination with embodiments.

[0028] With the continuous development of intelligence, multi-function and other aspects, the equipment needed to be arranged on the passenger car frame is increasing, which makes the space previously arranged on the frame for the fuel tank gradually insufficient. In this case, if the fuel tank is not improved, the new equipment will not have enough space to be arranged. If the size of the fuel tank is reduced, the volume will be reduced accordingly, which cannot meet the requirement of the vehicle for fuel quantity. Based on the above status, the present application improves the shape of the fuel tank, fully utilizes the originally idle space on the frame, so that more useful space is left on the frame without reducing the volume of the fuel tank, thereby meeting the requirement of installing other equipment.

[0029] Based on the above inventive concept, a basic embodiment of the fuel tank of the present application is as follows: as shown in Figures 1-6 In the basic embodiment, the fuel tank comprises a tank body 101, which is arranged at the front of the frame in use and is located at the middle position of the frame in the left-right direction. In order to more clearly illustrate the technical scheme of the fuel tank, the structure of the frame is first introduced as follows: as shown in Figures 3-6 The frame comprises a left longitudinal beam 102 and a right longitudinal beam 103, the lower front end of which is used for mounting a front suspension, and a triangular structural member 104 is arranged behind the front suspension. The triangular structural member 104 is used to increase the strength and reliability of the frame as a whole. There is a space with a certain width between the left longitudinal beam 102 and the right longitudinal beam 103 behind the triangular structural member 104. The flat space above the front suspension on the frame is an idle space, and the space above the triangular structural member 104 is also an idle space. The above structure of the frame is the prior art. The present application designs the structure of the fuel tank by studying the structural characteristics of the frame and exploring the space available on the frame.

[0030] The above-mentioned "positioned at the middle position of the frame in the left-right direction" is the position between the left longitudinal beam 102 and the right longitudinal beam 103. In the front-rear direction of the tank body 101, that is, the front-rear direction of the frame and also the front-rear direction of the passenger car, the tank body 101 is divided into three sections as shown in Figure 1As shown, the three sections are front section 11, middle section 12 and rear section 13 from front to back. The front section 11 corresponds to the space between the frame longitudinal beams above the front suspension, the middle section 12 corresponds to the space between the frame longitudinal beams above the inverted triangular structural member 104 behind the front suspension, and the rear section 13 corresponds to the space between the frame longitudinal beams behind the inverted triangular structural member. The outer side of the frame longitudinal beam is usually the arrangement space of the trunk, and since it is located between the left longitudinal beam 102 and the right longitudinal beam 103, the rear section does not encroach on the space of the trunk. Since the space on the frame gradually becomes spacious from front to back in the height direction, the bottom surface heights of the front section 11, the middle section 12 and the rear section 13 decrease in turn, so that the tank 101 forms an inverted ladder shape. When there is enough fuel, the front section 11, the middle section 12 and the rear section 13 of the fuel tank are filled with fuel, which can provide fuel for the engine. When the vehicle travels and the fuel is consumed, the fuel level drops, and the fuel will gradually gather in the rear section 13 of the fuel tank. The fuel suction pipe can be arranged here to ensure normal fuel supply.

[0031] A single oil pan interface 14 is arranged on the top of the tank 101, which reduces the number of openings on the tank 101, reduces the risk of oil leakage, and improves the appearance of the fuel tank.

[0032] The utility model discloses the shape of the tank 101 of fuel tank is improved, and on the premise that the volume of the fuel tank is not reduced or even increased, the useful space occupied by the fuel tank is reduced, thereby meeting the demand of arranging other equipment.

[0033] On the basis of the above basic embodiment, as a preferred embodiment, the tank 101 is provided with a limiting groove 15 for limiting the cooperation of the pressure rod 105 and the front and rear. Since it is arranged above the left longitudinal beam 102 and the right longitudinal beam 103, the width of the tank 101 in the left-right direction is equal to the distance between the left and right longitudinal beams, so that when arranged, the left and right side walls of the tank 101 are limited by the columns 106 arranged on the left longitudinal beam 102 and the right longitudinal beam 103, and the bottom is supported by the bottom cross beam 107 connected between the left longitudinal beam 102 and the right longitudinal beam 103. By arranging the limiting groove 15, when the fuel tank is installed, the pressure rod 105 connected to the corresponding column can be pressed in the limiting groove 15 to limit the up-down and front-back directions of the tank 101, and the fuel tank can be quickly fixed. Compared with the fixing mode of the special fuel tank support combined with the drawstring in the prior art, this fixing mode has the advantages of simple structure, high installation efficiency and better reliability.

[0034] On the basis of the above-mentioned embodiments, in order to make the box body have higher strength and higher reliability, as a preferred embodiment, the box body 101 is provided with a pressing rib 16, that is, the wall of the box body 101 is provided with a structure that the outer side wall is concave and the inner side wall is convex, through which the box body can have higher strength and prevent deformation and damage due to pressure and other factors during use.

[0035] In addition, as a further optimization of the above-mentioned embodiments, the box body 101 is also provided with a left oil filler 17 and a right oil filler 18, that is, the fuel tank of the utility model adopts a double oil filler structure, which can realize simultaneous oil filling on both sides, or even in the case of different oil filling, oil filling on the left side or the right side of the fuel tank can be realized, increasing the convenience of oil filling; in order to facilitate oil filling, the left oil filler pipe 108 can be connected to the left oil filler 17 and the right oil filler pipe 109 can be connected to the right oil filler 18 during use, so that the left oil filler pipe 108 extends to the left side of the frame and the right oil filler pipe 109 extends to the right side of the frame.

[0036] In the prior art, the box body of the fuel tank generally adopts metal material, which has the disadvantages of heavy weight and inconvenience in processing. In a preferred embodiment of the fuel tank of the utility model, the box body 101 adopts plastic material, so it is lighter in weight and can realize lightweight of the fuel tank and even the passenger car. Of course, in some embodiments, when the weight is not considered, the box body 101 can also be made of metal material, and the specific manufacturing process can be welding and the like, which is the prior art and will not be described here.
