[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0027] It should be understood that, in the description of the present application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements indicated must be in a particular orientation, constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features, that is, the features with "first", "second" can explicitly or implicitly include one or more of the features. In addition, unless otherwise stated, the meaning of "multiple" is two or more.

[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0029] As Figures 1-5 shown, the automobile oil tank door structure of the utility model embodiment includes a door body 1, a pressure relief switch 2, a lock core 3 and a rotating arm 4. In this embodiment, the door body 1 can be opened or closed by the lock core 3, when the door body 1 is opened, the lock core 3 drives the rotating arm 4 to rotate, triggering the pressure relief switch 2 to open, thereby relieving the high-pressure oil tank.

[0030] The door body 1 is movably mounted on the vehicle body, and is used to open or close the refueling port of the vehicle body. When the refueling port is opened, the refueling operation can be performed on the refueling port.

[0031] The pressure relief switch 2 is installed on the oil filler, and is used to open or close the pressure relief pipeline of the high-pressure oil tank. Specifically, the pressure relief switch 2 can control the valve on the pressure relief pipeline, so that the valve is opened, and the pressure relief pipeline is opened, thereby achieving pressure relief of the high-pressure oil tank.

[0032] The lock cylinder 3 is installed on the door body 1, and has a rotating end 31. When the rotating end 31 rotates, the lock cylinder 3 is switched between a locked position and an open position. Specifically, the locked position refers to a locked state of the lock cylinder 3, in which the position of the door body 1 is limited. The open position refers to an unlocked state of the lock cylinder 3, in which the position of the door body 1 can be moved.

[0033] The rotating end 31 drives the rotating arm 4 to rotate when the lock cylinder 3 is switched from the locked position to the open position, so that the rotating arm 4 abuts against the pressure relief switch 2 and opens the pressure relief switch 2. In this way, when the door body 1 is opened, the rotating arm 4 triggers the pressure relief switch 2, and finally achieves pressure relief of the high-pressure oil tank.

[0034] Based on the above structure, the lock cylinder 3 is installed on the door body 1, and has a rotating end 31. When the rotating end 31 rotates, the lock cylinder 3 is switched between a locked position and an open position. The rotating end 31 drives the rotating arm 4 to rotate when the lock cylinder 3 is switched from the locked position to the open position, so that the rotating arm 4 abuts against the pressure relief switch 2 and opens the pressure relief switch 2. Therefore, by opening the door body 1 through the lock cylinder 3, pressure relief of the high-pressure oil tank can be achieved at the same time, which is convenient to use.

[0035] As shown in Figure 2 In some embodiments, the pressure relief switch 2 has a press head 21 that can be lifted and lowered. The rotating end 31 drives the rotating arm 4 to rotate, so that the rotating arm 4 abuts against and presses down the press head 21, and the pressure relief switch 2 is opened. In this way, the pressure relief switch 2 is opened, the pressure relief pipeline is opened, and pressure relief of the high-pressure oil tank is achieved.

[0036] In some embodiments, the side edge of the door body 1 is hinged to the vehicle body. In order to ensure that the lock cylinder 3 has an installation position, the lock cylinder 3 is located away from the hinged side edge of the door body 1.

[0037] As shown in Figure 1 and 2 In some embodiments, the rotating end 31 is located on the side of the door body 1 close to the vehicle body. In this way, the rotating end 31 can extend into the oil filler and match the position of the pressure relief switch 2.

[0038] As shown in Figure 2 and 4As shown, in some embodiments, the rotating arm 4 includes a mounting portion 41 and an extension portion 42. The mounting portion 41 is mounted on the rotating end 31, and the extension portion 42 is located at one end of the mounting portion 41 and extends towards the pressure relief switch 2. The rotating end 31 drives the extension portion 42 to rotate through the mounting portion 41, causing the extension portion 42 to abut against the pressure relief switch 2 and opening the pressure relief switch 2. In this way, the pressure relief pipeline can be opened, realizing the pressure relief of the high-pressure oil tank, and at this time, the door 1 can be opened, making the operation simple and avoiding misoperation.

[0039] like Figure 3 As shown, in some embodiments, when the lock cylinder 3 is in the locked position, the extension 42 engages with the vehicle body latch. At this time, the rotating arm 4 will not abut against the pressure relief switch 2.

[0040] like Figure 5 As shown, in some embodiments, when the lock cylinder 3 is in the open position, the extension 42 disengages from the vehicle body latch. At this time, the rotating arm 4 will not abut against the pressure relief switch 2.

[0041] The rotating arm 4 will only abut against the pressure relief switch 2 when the lock cylinder 3 rotates from the locked position to the open position, so that the pressure relief switch 2 will only be triggered when needed.

[0042] In some embodiments, the mounting portion 41 and the extension portion 42 are perpendicular to each other, making the structure of the swing arm 4 compact.

[0043] In some embodiments, the mounting portion 41 and the rotating end 31 are connected by rivets. This ensures a stable connection between the mounting portion 41 and the rotating end 31 during frequent use.

[0044] like Figure 1 As shown, in some embodiments, the lock cylinder 3 has a keyhole 32, which is located at the end of the lock cylinder 3 opposite to the rotating end 31, and extends outward from the door body 1. By inserting a key into the keyhole 32 and turning the key, the rotating end 31 of the lock cylinder 3 can be rotated, and the rotating arm 4 can be further rotated.

[0045] In some embodiments, when the lock cylinder 3 is in the locked or unlocked position, the rotating arm 4 is separated from the pressure relief switch 2, at which time the pressure relief switch 2 is closed.

[0046] Further, the pressure relief switch 2 outputs a high signal to the VCU when it is opened, and the VCU controls the high-pressure tank to release pressure; the pressure relief switch 2 outputs a low signal to the VCU when it is closed, and the VCU controls the high-pressure tank to reset. The pressure relief switch 2 is a micro switch, and the VCU is a vehicle control unit. During the whole process of the lock core 3 from the locked position to the open position, the micro switch outputs a low-high-low signal to the VCU, which has a rising edge and a falling edge, so as to realize the pressure relief and reset of the high-pressure tank, and the realization is specifically achieved by controlling the opening or closing of the valve on the pressure relief pipeline of the high-pressure tank.

[0047] Based on the above-mentioned automobile tank door structure, the structure is simple, practical, safe, and low in modification cost.

[0048] The above-mentioned is only the preferred embodiment of the present application, and it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present application.
