[0031] In order to make the purpose, advantages and characteristics of the utility model more clear, the utility model is further described in detail below in combination with the drawings and specific embodiments.

[0032] Referring to Figure 1 , Figure 2 , Figure 3 , the embodiment provides an electric control hydraulic actuator oil can with a breathable cooling structure, which comprises an oil can body 1, an oil inlet hole 2 and an oil outlet hole arranged on the oil can body 1. Generally, the oil inlet hole 2 is located above the oil can body 1, facilitating smooth and rapid injection of oil into the oil can body 1. The oil outlet hole is located below the side of the oil can body 1 and is used for connecting the electric control hydraulic actuator to supply oil.

[0033] The oil tank body 1 is provided with a partition plate 3, which is arranged horizontally and forms an oil cooling area with the upper inner wall of the oil tank body 1, so as to facilitate the cooling and backflow of gaseous oil. The partition plate 3 and the lower inner wall of the oil tank body 1 form an oil storage area for storing oil.

[0034] The partition plate 3 is provided with a gas permeable hole 4, which is generally located on one side of the partition plate 3 close to the side wall of the oil tank body 1, or can be arranged at any position on the partition plate 3 according to design requirements. The gas permeable hole 4 is used to communicate the oil cooling area and the oil storage area.

[0035] The oil cooling area is a labyrinth structure, which is used to provide a cooling channel for gaseous oil. The labyrinth structure can be composed of a first baffle plate 5, which can be designed to have multiple arc bends. The first baffle plate 5 is installed on the inner wall of the oil tank body 1 and is inclined downward as a whole.

[0036] In some embodiments, the labyrinth structure can also be designed to be composed of multiple first baffle plates 5 arranged in sequence and staggered. Each first baffle plate 5 is connected to the inner wall of the oil tank body 1 on one side and inclined downward on the other side. The entrance of the labyrinth structure is located above the gas permeable hole 4 and is the highest position in the oil cooling area, and the exit is the lowest position in the oil cooling area.

[0037] When the oil in the oil storage area is atomized into gaseous oil, the gaseous oil enters the oil cooling area through the gas permeable hole 4, moves upward and gradually cools into liquid oil in the labyrinth structure. Then the liquid oil moves downward again through the labyrinth structure and enters the oil storage area through the gas permeable hole 4 for repeated use. At the same time, the gas in the oil tank body 1 is discharged through the oil filling hole 2.

[0038] In order to improve the efficiency of oil backflow, the height of the upper surface of the partition plate 3 gradually decreases from the position far away from the gas permeable hole 4 to the position close to the gas permeable hole 4, so that the gas permeable hole 4 is located at the lowest position of the upper surface.

[0039] In order to improve the air permeability of the oil tank body 1, a vent plug is arranged on the oil filling hole 2 for discharging gas in the oil tank body 1.

[0040] At the same time, the oil tank body 1 is provided with an oil filling pipeline 6, one end of which communicates with the oil filling hole 2, and the other end is connected with the partition plate 3, and the oil filling hole 2 is communicated with the oil storage area. In addition, the oil filling pipeline 6 is also provided with two second baffle plates 7 arranged in an eight-shaped longitudinal section and staggered up and down, which are used to block the overflow of oil from the oil filling hole 2. When filling oil, a hose can be used, which is inserted into the oil storage area from the oil filling pipeline 6, and the oil is filled. After filling, the hose is removed. Therefore, when the vehicle is jolted, the oil in the oil storage area will only splash into the oil filling pipeline 6 and be blocked by the second baffle plate 7, and the phenomenon of oil spilling will not occur.

[0041] The oil can body 1, the partition plate 3 and the labyrinth structure of the embodiment are integrated and can be formed by a mold once, the overall structure is simple, and processing is more convenient.

[0042] The material of the first baffle 5 and the second baffle 7 is thermoplastic resin, the cost of which is lower, easy to form, and better impact resistance.

[0043] The utility model considers the drawback of traditional oil can oil injection and exhaust scheme, increases the breathable labyrinth in the oil can body, and separates the breathable hole and the oil injection hole, greatly forms the guarantee function to the execution mechanism oil can cleanliness, avoids that the oil liquid in the oil can causes the execution mechanism to fail because of the vehicle driving bumping and causes the oil spill.

[0044] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, rather than limit them. Although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement to part or all of the technical features, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the utility model.
