Referring to the drawings, an embodiment of the present invention provides a liquid level detecting device 100 including a sleeve 10, a float 20, an indicator 30, and a liquid level indicator 40. The liquid level detection device 100 of the present application is used for detecting the liquid position of the liquid storage container 200, specifically, the liquid level that the liquid storage container 200 can store may be liquid such as water, oil, etc., and the liquid storage container 200 is specifically a water storage tank, an engine oil tank, etc., and is not limited herein.

The indicator 30 is connected with the floating member 20, the liquid level indicator 40 is arranged on the liquid storage container 200, the liquid level indicator 40 can display a plurality of liquid level values, wherein the floating member 20 can float on liquid in the liquid storage container 200 and can respond to the movement of the amount of the liquid in the liquid storage container 200, and the indicator 30 can follow the movement of the floating member 20 to point to the corresponding liquid level value. Specifically, the indicator may be a pointer or other components having indicating function, and is not limited herein.
In this way, by arranging the sleeve 10 at the bottom of the liquid storage container 200, liquid can enter the sleeve 10 through the communication hole 11, so that the liquid level in the sleeve 10 and the liquid storage container 200 is in a consistent state, and the floating member 20 located therein can float up and down along the axial direction of the sleeve 10 under the action of the guide surface 21 along with the change of the liquid level in the liquid storage container 200, so that the liquid level value of the indicating member 30 directed to the liquid level indicating member 40 can be changed along with the movement of the floating member 20 to direct to the correct liquid level value. The liquid level detection device 100 of the present application, because the sleeve 10 is connected to the bottom of the liquid storage container 200, and the floating member 20 is disposed in the sleeve 10, the liquid level detection device will not be touched with other components in the liquid storage container 200 when detecting, and the accuracy of the detected liquid level will not be affected. In addition, most of the structure of the liquid level detection device 100 is disposed inside the liquid storage container 200, so that the device can be prevented from being interfered by the external environment, and the safety of the device is improved.
Specifically, in the embodiment of the present invention, the sleeve 10 is cylindrical, and in other embodiments, the sleeve 10 may also be other cylindrical structures, such as square, etc., without limitation.
In some embodiments, the guiding surface 21 of the floating member 20 is annular, so that the floating member 20 can be circumferentially fitted to the inner circumferential wall of the sleeve 10, thereby making the floating of the floating member 20 in the axial direction of the sleeve 10 more reliable and stable.
Specifically, the floating member 20 is a cylinder shape matching the shape of the sleeve 10, and in other embodiments, it may be another cylinder structure, such as a square shape, etc., without limitation.
In some embodiments, the material of the floating member 20 is plastic, and further, the floating member 20 is a hollow member, so that the buoyancy of the floating member 20 is more effective, and thus the liquid level change can be more accurately responded.
In some embodiments, the communication hole 11 of the sleeve 10 is located near the bottom of the reservoir 200, thus enabling the float to be at a lower position to detect a lower level value.
Specifically, the communication hole 11 penetrates the sleeve 10 in the radial direction of the sleeve 11. Therefore, the communication area is larger, and the liquid level change in the sleeve 2 can respond to the liquid level change of the liquid storage container 200 in time. In other embodiments, the communication hole 11 may also be disposed on a side surface of the sleeve 11 facing the liquid storage container 200, and is not limited herein.
In some embodiments, the liquid level detecting device 100 further includes a first transmission member 50 and a second transmission member 60, the first transmission member 50 is connected to the floating member 20, the first transmission member 50 can move back and forth in a first direction under the action of the floating member 20, the second transmission member 60 is in transmission connection with the first transmission member 50, the second transmission member 60 can convert the movement of the first transmission member 50 into a rotary motion, and the indicating member 30 is disposed on the second transmission member 60. Therefore, the floating member 20 can be converted into a rotary motion by the matching motion of the first transmission member 50 and the second transmission member 60, so as to drive the indicating member 30 to rotate to indicate the corresponding liquid level value, thereby saving the occupied space and being easy to arrange. Specifically, the first direction is the axial direction of the sleeve 10. Specifically, an opening 12 is formed at an end of the sleeve 10 axially away from the liquid storage container 200, and an end of the first transmission member 50 extends out of the opening 12 to be connected with the second transmission member 60 in a transmission manner.
In one embodiment, the first transmission member 50 includes a transmission rack, and the second transmission member 60 includes a transmission gear engaged with the transmission rack. The gear and the rack are simple in matching mode, and transmission is stable, so that the detected liquid level value is more accurate.
Further, the second transmission member 60 includes a transmission body 61 and a rotation shaft 62 connected to the transmission body 61, and the indication member 30 is provided at an end of the rotation shaft 62. Because the indicator 30 is arranged at the end part of the rotating shaft 62, the indicator 30 can definitely respond to the rotation of the second transmission 60, and the detection accuracy and timeliness are further improved.
Further, the liquid level indicator 40 is disposed outside the liquid storage container 200, and the rotating shaft 62 penetrates the liquid level indicator 40, so that the indicator 30 is exposed on the outer surface of the liquid level indicator 40. The indicator 30 exposed to the outer side surface enables a more clear view of the level value on the level indicator 40. Specifically, the rotation shaft 62 axially protrudes to one side of the transmission body 61 to penetrate the liquid level indicator 40. It is noted that, in the present embodiment, the outer side surface of the liquid level indicator 40 is provided with a liquid level dial.
It should also be noted that the liquid level indicator 40 may be disposed completely outside the liquid storage container 200, or may be disposed in the mounting through hole of the liquid storage container 200, so that a portion thereof is disposed outside the liquid storage container 200, which is not limited herein. However, it should be understood that when the liquid level indicator 40 is completely disposed outside the liquid container 200, the rotating shaft 62 needs to penetrate through the sidewall of the liquid container 200 and the liquid level indicator 40.
In some embodiments, the level indicator 40 defines a mating hole that mates with the rotating shaft 62. The mating holes can be matched with the rotating shaft 62, so that the rotating shaft 62 can be supported and circumferentially limited in the mating holes, and the influence on the indicating precision caused by the bending of the rotating shaft 62 is avoided.
As shown in fig. 3, in some embodiments, the rotating shaft 62 includes a first shaft segment 621 and a second shaft segment 622, one end of the first shaft segment 621 is connected to the transmission body 61, the other end of the first shaft segment 621 is connected to one end of the second shaft segment 622, the other end of the second shaft segment 622 is provided with an indicator 30, wherein the indicator 30 abuts against an outer side surface of the liquid level indicator 40, an abutting portion 623 is arranged at a connection position of the first shaft segment 621 and the second shaft segment 622, and the abutting portion 623 can abut against an inner side surface of the liquid level indicator 40 to limit the axial movement of the rotating shaft 62 along the liquid level indicator. Thus, the axial movement of the rotating shaft 62 can be prevented from affecting the precision of detection. Specifically, the abutting portion 433 includes a step portion, and more specifically, the shaft diameter of the first shaft segment 621 is larger than the shaft diameter of the second shaft segment 622 to form a step portion at the junction of the first shaft segment 621 and the second shaft segment 622.
It should also be noted that when the level indicator 40 is disposed entirely outside of the reservoir 200, the abutment 623 should act indirectly on the inside surface of the level indicator 40 by abutting against the inside wall of the reservoir 200 to cooperate with the indicator 30 to form an axial stop for the rotating shaft 62.
Based on the same inventive concept, the application also provides an engine oil tank, which comprises an oil pan and the liquid level detection device 100, wherein the oil pan is used for storing engine oil.
It is noted that the oil pan is an embodiment of the reservoir 200.
Based on the same inventive concept, the application also provides a vehicle comprising the engine oil tank.
