The present invention relates to an oil reservoir for storing oil for use in a vehicle. More specifically, the transparent part is formed on the upper part, and the measuring tube is attached to the lower side of the transparent part, and the inside of the measuring tube is provided with an oil cover to which the first and second indicator plates of different colors are hinged so as to rotate through buoyancy. Each indicator plate rotates according to the amount of oil stored in the tank, and the horizontal and vertical states of each indicator plate according to the rotation are displayed through the transparent part, so that the amount of oil stored in the reservoir tank can be measured from the outside without opening the oil cover. It relates to an oil reservoir.

Generally, various oils such as oils for hydraulic devices and oils for lubrication are widely used in vehicles, and these oils are usually stored in oil reservoirs, and according to each need, a certain amount is used and gradually consumed. Depending on the device, after a certain period of time, the oil is replenished or replaced.

As an example of such an oil reservoir, the oil reservoir used for power steering is operated on the principle of improving the steering feeling of the driver by generating oil pressure by an oil pump using oil stored in the oil reservoir. The stored oil is discharged by the oil pump and introduced into the gearbox of the steering device, and has a circulation structure flowing into the oil reservoir through the pipe.

Therefore, in order to operate the power steering smoothly, an appropriate amount of oil that can be circulated according to the change in the oil discharge amount of the oil pump must be stored in the oil reservoir. The oil should not leak, even if present.

On the other hand, too much oil stored in the oil reservoir exceeds the prescribed amount may be an indicator indicating that the oil is not properly circulated, and oil leakage from the oil reservoir may be too large. On the contrary, when the amount of oil stored in the oil reservoir is less than the prescribed amount, the discharge amount of the oil required by the oil pump cannot be satisfied, so that the rotational force of the oil pump does not occur normally, and thus the oil pump may be damaged. Therefore, it is very important for the smooth operation of the vehicle that the amount of oil stored in the oil reservoir is maintained at an appropriate level.

Like the oil reservoir used for power steering as described above, other various oil reservoirs mounted on the vehicle also need to maintain an appropriate amount of oil stored therein so that the device connected to the oil reservoir can operate smoothly.

Therefore, oil gauges are installed in various oil reservoirs mounted on the vehicle so as to check an appropriate storage amount of oil required for each oil reservoir.

1 is a view schematically showing an oil gauge method of an oil reservoir generally used according to the prior art.

In general, the oil reservoir 1 includes a reservoir tank 10 in which an oil inlet 11 is formed on an upper surface thereof, and an oil cover 20 for opening and closing the oil inlet 11. The oil reservoir 1 is installed in the oil reservoir 1. The method of the oil gauge is a method of measuring the height of the oil displayed on the rod gauge 30 by connecting the rod gauge 30 engraved on the oil cover 20, as shown in Figure 1 (a) or Figure 1 As shown in (b) of the reservoir tank 10 is made of a translucent material, and the scale 40 is directly displayed on the side surface of the reservoir tank 10 to measure the height of the oil in appearance, etc. are used. .

However, in the method of measuring the amount of oil in this manner, in the case of FIG. 1 (a), each time the user measures the oil height, the oil cover 20 is opened and the rod gauge 30 is pulled out of the oil displayed on the rod gauge 30. There is an inconvenience to measure the height and accordingly there was a problem such that the device malfunctions by leaving the user without periodic inspection. In addition, in case (b) of FIG. 1, when the reservoir tank 10 is contaminated by oil, it is difficult to identify the scale 40 displayed on the side, and the height of the oil is also difficult to accurately identify. As a result, the reservoir tank 10 of the translucent material is changed to be opaque due to heat inside the engine room, and thus there is a problem in that the height of the oil stored therein cannot be identified.

Therefore, the present invention has been invented to solve this problem, the transparent part is formed on the upper portion, the measuring tube is attached to the lower side of the transparent portion, and the inside of the measuring tube has a first and second indicator plates of different colors, respectively, so as to rotate through buoyancy. A hinged oil cover is provided, and each indicator plate rotates according to the amount of oil stored in the reservoir tank, and the horizontal and vertical states of each indicator plate according to the rotation are displayed through the transparent part, thereby opening the reservoir from the outside without opening the oil cover. It is an object of the present invention to provide an oil reservoir capable of measuring the amount of oil stored in a tank.

In order to achieve the above object, the present invention, in the oil reservoir comprising a reservoir tank in which an oil inlet is formed on the upper surface and an oil cover for opening and closing the oil inlet, the oil cover is a cover plate having a transparent portion in the center ; A measuring tube attached to a lower surface of the transparent part of the cover plate and having a lower surface opened; A first indicator plate rotatably coupled to a position at an inner predetermined height of the measurement tube; And a second indicator plate positioned below the first indicator plate and rotatably coupled to the inside of the measurement tube, wherein the first and second indicator plates rotate by buoyancy caused by oil. Provide oil reservoir.

In this case, a fixing protrusion is provided inside the measuring tube to restrain the first and second indicator plates so as to be rotatable only by a predetermined angle, and by the fixing protrusions, the first indicator plate is in a leftward horizontal state in a downward vertical state. It is preferable that only the angle α is rotatable and the second indicator plate is rotatable only by the angle β from the leftward horizontal state to the upward vertical state.

The oil cover may further include a third indicator plate positioned below the second indicator plate and fixed horizontally to the inside of the measurement tube, wherein each indicator plate is formed in a different color. It is desirable to be.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

2 is a perspective view briefly showing the shape of the oil cover of the oil reservoir according to an embodiment of the present invention, Figure 3 is a cross-sectional view taken along the line "A-A" of FIG.

The oil cover 200 is to open and close the oil inlet (not shown) formed on the upper surface of the reservoir tank (not shown), as shown in Figure 2 the oil cover according to an embodiment of the present invention is a transparent portion in the center The cover plate 210 and the cover plate 210 are formed on the transparent part 211 of the cover plate 210 and the lower surface is composed of a measuring tube 220 is open. The measuring tube 220 may be formed in a hollow cylindrical shape as shown in the figure as a hollow pipe shape, but the vertical cross-sectional shape in the longitudinal direction may be formed in various shapes such as triangle or square. Meanwhile, the transparent part 211 formed at the center of the cover plate 210 may be made of a transparent material such as transparent acrylic or glass.

The first indicator plate 221 and the second indicator plate 223 are provided at a position of a predetermined height inside the measurement tube 220, and the first indicator plate 221 is located at an upper side of the measurement tube 220. It is hinged to be rotatable about the first hinge axis 222, the second indicator plate 223 is located on the lower side of the first indicator plate 221 is rotatable about the second hinge axis 224. Hinged so as to.

As shown in the enlarged view of FIG. 2, the oil reservoir according to the present invention observes an inner space of the measuring tube 220 positioned in the reservoir tank internal space through the transparent portion 211 formed at the center of the oil cover 200. Therefore, the first and second indicator plates 221 and 223 coupled to the inside of the measurement tube 220 are observed from the outside of the oil cover 200.

Therefore, when the first indicator plate 221 is in the horizontal state, the first indicator plate 221 is observed through the transparent portion 211 regardless of the state of the second indicator plate 223, and the first indicator plate When 221 is in the vertical state, the bottom surface of the second indicator plate 223 and the reservoir tank is observed through the transparent part 211 according to the horizontal state and the vertical state of the second indicator plate 223. In this case, as shown in FIGS. 2 and 3, the third indicator plate 225 is fixedly coupled to the lower side of the second indicator plate 223 so that both the first and second indicator plates 221 and 223 are vertical. In this case, it is preferable that the third indicator plate 225 is observed through the transparent part 211, not the bottom surface of the reservoir tank.

Since each indicator plate is observed through the transparent portion 211 of the cover plate 210 as described above, each indicator plate is preferably formed to be visually identifiable. For example, the indicator plate is observed through the transparent portion 211. Different letters or symbols may be formed on the upper surface of each of the indicator plates to form letters “MAX” and “MIN” on the first and second indicator plates 221 and 223, respectively. However, it is preferable to make the intuitive identification by forming the color of each indicator board differently than the identification by such letters or symbols.

Meanwhile, the principle in which the first and second indicator plates 221 and 223 rotate about the hinge axes 222 and 224 is buoyant to the first and second indicator plates 221 and 223 due to the oil stored in the measuring tube 220. The rotation of the first and second indicator plates 221 and 223 is different depending on the amount of stored oil depending on the amount of stored oil, that is, the height of the stored oil. At this time, according to an embodiment of the present invention, the fixing projections 226 restraining the rotation of each of the indicator plates 221 and 223 so that the first and second indicator plates 221 and 223 rotate only a predetermined section are provided at a predetermined position. As shown in FIG. 3, the first indicator plate 221 is constrained to rotate only by an angle α from the downward vertical state to the left horizontal state, and the second indicator plate 223 is the angle from the left horizontal state to the upward vertical state. It is desirable to be constrained to rotate only by (β). As such, when the rotation of each of the indicator plates 221 and 223 is restricted, each of the indicator plates 221 and 223 represents a constant rotation state corresponding to the corresponding height according to the height of the stored oil.

In addition, as shown in the enlarged view of FIG. 3, the first and second indicator plates 221 and 223 have an inner chamber 227 into which air is inserted into each of the indicator plates 221 and 223 so that buoyancy can be greatly applied. Preferably, the inner chamber 227 is preferably formed at the end of each of the indicator plates (221, 223) so that the rotational force due to the buoyancy force on each of the indicator plates (221, 223).

Figure 4 is a simplified view illustrating the oil amount measurement principle according to the stored oil amount of the oil reservoir according to the present invention.

Since the lower surface of the measuring tube 220 is opened and positioned in the reservoir tank, when oil is stored in the reservoir tank, oil is also introduced into the measuring tube 220 at the same time to achieve the same height as the oil stored in the reservoir tank. do. Accordingly, the height of the first hinge shaft 222 of the first indicator plate 221 is the maximum height of the oil amount required for the corresponding oil reservoir so as to check the proper amount of oil in various oil reservoirs. The height of the second hinge shaft 224 is preferably set to be the minimum height of the oil amount.

According to this structure, the comparison with respect to the states (a), (b), and (c) of FIG. 4 will be described.

Figure 4 (a) is the case where the amount of oil stored in the oil reservoir is less than the minimum height, (b) is the case where the amount of oil stored in the oil reservoir is between the maximum and minimum height of the appropriate amount, (c) is the oil The amount of oil stored in the reservoir is above the maximum height.

First, in the state (a) of FIG. 4, as shown in the drawing, the first indicator plate 221 maintains a vertical state due to its own weight, and the second indicator plate 223 also maintains a horizontal state due to its own weight. As described above with reference to FIG. 3, the second indicator plate 223 is constrained by the fixing protrusion 226 to maintain a horizontal state. Since the third indicator plate 225 is a fixed structure that can not rotate, it maintains a fixed state irrespective of the buoyancy of the oil. Therefore, in this state (a), the second indicator plate 223 in a horizontal state is displayed through the transparent part 211.

Next, in the state (b) of FIG. 4, the first indicator plate 221 maintains a vertical state due to its own weight, and the second indicator plate 223 has a buoyancy force due to oil acting on the second hinge shaft 224. Ascending and rotating about the center, it becomes vertical as shown in the drawing. Therefore, in the state (b), since the first and second indicator plates 221 and 223 are both in the vertical state, the third indicator plate 225 is displayed through the transparent part 211.

Finally, in the state (c) of FIG. 4, the second indicator plate 223 maintains a vertical state due to buoyancy, and the first indicator plate 221 also acts as a buoyancy force due to oil to move the first hinge shaft 222. Ascending and rotating about the center is horizontal as shown in the figure. In this case, when the height of the oil is greater than or equal to the height of the first hinge shaft 222, the first indicator plate 221 is subjected to the buoyancy to further increase the rotation above the horizontal state, but as described in Figure 3 by the fixing projections 226 Since the rotation beyond the horizontal state is constrained, the first indicator plate 221 is maintained in the horizontal state. Therefore, in the state (c), the first indicator plate 221 in the horizontal state is displayed through the transparent part 211.

Summarizing the above states, the second indicator plate 223 is displayed through the transparent portion 211 in the state (a) where the amount of stored oil is less than or equal to the minimum height, and the third indicator plate 225 in the (b) state at an appropriate level. ) Is displayed and the first indicator plate 221 is displayed in the state (c) that is greater than or equal to the maximum height.

Since different indicators are displayed according to the amount of oil as described above, the colors of the first to third indicators 221, 223, and 225 may be formed of yellow, red, and green, respectively, so that each indicator may be intuitively identified. will be.

On the other hand, as shown in the drawing, each indicator plate is preferably formed in a shape corresponding to half of the cross-sectional shape of the inner side of the measuring tube 220 so that the oil flowing into the inside of the measuring tube 220 is smooth, Since the first and second indicator plates 221 and 223 may rotate by hinge coupling, the first and second indicator plates 221 and 223 may be formed in the same shape as the cross-sectional shape of the measuring tube 220. However, since the third indicator plate 225 is fixedly coupled unlike the first and second indicator plates 221 and 223, the third indicator plate 225 is formed in the same shape as the cross-sectional shape of the inside of the measurement tube 220 in order to introduce oil into the measurement tube 220. It should not be, it is preferably formed smaller than half of the inner cross-sectional area of the measuring tube 220 as shown in the figure.
