It can be understood that, when it is necessary to adjust the orientation of the oil filling opening 35, it is only necessary to make the first fixing structure 41 and the second fixing structure 42 approach each other, so that the corrugated tube 33 inclines towards the direction in which the adjusting mechanism is disposed, and then to make both ends of the adjusting member respectively connect with the first fixing structure 41 and the second fixing structure 42, so as to avoid the first fixing structure 41 and the second fixing structure 42 from being far away from or approaching again, i.e. to make the position between the first fixing structure 41 and the second fixing structure 42 relatively fixed, so as to ensure that the relative position between the first protruding portion 331 and the second protruding portion 332 on the corrugated tube 33 is fixed, and to avoid the corrugated tube 33 from returning to the position before the inclination, so as to keep the orientation of the oil filling opening 35 from changing any more, and.

According to the oil tank assembly provided by the embodiment of the invention, only the first fixing structure 41 arranged on the first protruding portion 331 and the second fixing structure 42 arranged on the second protruding portion 332 are required to be close to each other, so that the first protruding portion 331 and the second protruding portion 332 on the corrugated pipe 33 can be driven to be close to each other, the corrugated pipe 33 is inclined, at this time, the direction of the pipe orifice at one end of the second straight pipe 34, which is far away from the corrugated pipe 33, is also inclined, then the first fixing structure 41 and the second fixing structure 42 are respectively connected by using the adjusting member, so that the positions of the first fixing structure 41 and the second fixing structure 42 are relatively fixed, further the direction of the oil filling opening 35 is adjusted, the requirement on the direction of the oil filling opening 35 when a truck is refitted can be better met, and the universality of the oil tank assembly is better.

Further, a plurality of adjusting mechanisms can be distributed on the circumference of the corrugated pipe 33, so that a plurality of directions on the circumference of the corrugated pipe 33 can be adjusted, the orientation of the oil filling port 35 can be adjusted in a plurality of directions, the requirements of different installation environments on the orientation of the oil filling port 35 can be better met, and the application range of the oil tank assembly is further expanded. It is understood that when one side of the bellows 33 is compressed to be short and inclined at this time, the opposite side of the bellows 33 to the one side is elongated.

Specifically, the respective adjustment mechanisms may be uniformly distributed in the circumferential direction of the bellows 33, so that the orientation of the oil filler port can be easily adjusted in a plurality of directions.

As shown in fig. 6, the number of the adjusting mechanisms may be four, and each adjusting mechanism is uniformly distributed in the circumferential direction of the bellows 33, so as to effectively avoid the structure of the oil tank assembly from being too complex, and better ensure that the orientation of the oil filling port 35 can be adjusted in multiple directions.

In another embodiment provided by the present invention, the first fixing structure 41 may be a first fixing rod, the second fixing structure 42 may be a second fixing rod, and the adjusting member may be a first rope; one end of the first rope is fixedly connected with the first fixing rod, and the other end of the first rope is used for being connected with the second fixing rod. Through this scheme, when the orientation of oil filler hole was adjusted to needs, only need make the second dead lever be close to first dead lever, then with first rope fix on first dead lever can, it is convenient to see its convenient operation, adjustment mechanism's simple structure.

In a further embodiment of the present invention, as shown in fig. 3 to 5, the adjusting mechanism may further include a tightening buckle 44, the first fixing structure 41 and the second fixing structure 42 are both hook-shaped structures, and the adjusting element is a second rope 43; an accommodating space is formed between the second fixing structure 42 and the second protrusion 332; a first end of the second rope 43 is hooked on the first fixing structure 41, a second end of the second rope 43 passes through the accommodating space and is connected with the tightening buckle 44, the tightening buckle 44 is sleeved on the second end, and the tightening buckle 44 has an empty sleeve position and a locking position; the second fixing structure 42 and the second protrusion 332 in the accommodating space are respectively provided with a limiting surface for blocking the tightening buckle 44. By adopting the scheme, the first fixing structure 41 and the second fixing structure 42 can be enabled to be close to each other only by enabling the tightening buckle 44 to be in the empty sleeve position and then pulling the second end of the second rope 43 upwards, so as to realize the adjustment of the orientation of the oil filling port 35, and then the tightening buckle 44 is arranged at the locking position, namely the tightening buckle 44 is tightly sleeved on the second end, so that the tightening buckle 44 is prevented from sliding on the second end, and meanwhile, the situation that the second fixing structure 42 is far away from the first fixing structure 41 can be avoided by utilizing the limiting effect of the second fixing structure 42 and the second bulge 332 on the limiting surface of the tightening buckle 44, so as to keep the orientation of the oil filling port 35 unchanged; moreover, the adjusting mechanism can facilitate the adjustment of the orientation of the oil filler 35, and also can facilitate the maintenance and replacement of the second rope 43.
