Description
Technical Field
The present invention relates to a urea solution filler pipe apparatus, and more particularly, to a urea solution filler pipe apparatus that is installed on a floor of a vehicle body to inject urea solution into a urea solution tank.
Background
Environmentally friendly vehicles are being developed worldwide, and vehicle exhaust emission standards of various countries are being tightened gradually. In addition, automotive manufacturers have developed environmentally friendly diesel vehicles through the control of carbon dioxide.
The core of the diesel vehicle emission gas standard is nitrogen oxides and particulate matter, and LNT and UREA-SCR have attracted public attention in the technology of reduction of nitrogen oxides among nitrogen oxides and particulate matter. In particular, the UREA-SCR is useful in reducing nitrogen oxides emitted from diesel engines of large vehicles.
In UREA-SCR, a harmless UREA solution is injected into an exhaust system and the injected UREA solution is converted into ammonia by pyrolysis, wherein a selective reduction system reacts the converted ammonia with nitrogen oxides and converts the nitrogen oxides into harmless components such as water and nitrogen, wherein a storage system separately storing the UREA solution is required.
The urea solution storage system includes a urea solution tank, a pump, an inlet, piping, cables, and various sensors.
However, in the urea solution storage system of the related art, the inlet is generally disposed near the fuel inlet, and therefore, a filler pipe connecting the inlet and a urea solution tank disposed under the vehicle body is unnecessarily lengthened. Therefore, the layout becomes complicated and the cost increases.
In addition, when the strongly alkaline urea solution is splashed back to the inlet by the pressure of the urea solution tank, the odor flows into the interior of the vehicle, causing discomfort to the passengers.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Fig. 1 is a partially cut-away perspective view of a urea solution filler pipe apparatus according to an exemplary embodiment of the present invention, fig. 2 is a cross-sectional view of the urea solution filler pipe apparatus according to an exemplary embodiment of the present invention, and fig. 3 is an enlarged schematic view of a portion a of fig. 2.
Referring to the drawings, a urea solution filler pipe apparatus 100 according to an exemplary embodiment of the present invention is installed on a floor of a vehicle body 10 to inject urea solution into a urea solution tank 20 formed at one side of a fuel tank, and the urea solution filler pipe apparatus 100 is connected to the urea solution tank 20.
As shown in fig. 1 to 3, this urea solution fill pipe apparatus 100 includes a lid body 110, a fill pipe body 120, an opening/closing cap (closing cap)140, and a seal member 150.
The cover body 110 is selectively and detachably mounted on the floor of the vehicle body 10 to correspond to the urea solution tank 20. A through hole 112 is formed in the center of the cover 110.
Here, the cover body 110 includes a flange portion 114 and a connection portion 116.
The flange portion 114 is connected to the vehicle body 10. Further, the connecting portion 116 integrally extends downward at the bottom of the flange portion 114 and contacts the fill pipe body 120.
The cover 110 configured as above may be detachably mounted to the vehicle body 10. Therefore, when the urea solution tank 20 or the filler pipe body 120 needs to be repaired, the cover body 110 can be easily detached from the vehicle body 10.
In this exemplary embodiment, the fill pipe body 120 is provided at the bottom of the cover body 110 and is mounted on the urea solution tank 20.
Such fill tube body 120 can include a fill port 122, a weld flange portion 124, a fill tube neck 131, a check chamber 132, and a septum 133.
In the filling port 122, an opening and closing cover 140 is mounted on the top, and a filling hole 121 is formed in the center in the longitudinal direction.
One or more guide protrusions 123 may be formed on the inner circumference of the injection hole 121 in the longitudinal direction.
When the urea solution replenishing gun 170 is inserted into or separated from the injection hole 121, the guide protrusion 123 may stably guide the movement of the urea solution replenishing gun 170 while contacting the outer circumference of the urea solution replenishing gun 170.
In this example embodiment, the welding flange portion 124 integrally extends outward in the circumferential direction from the bottom of the fill port 122, and is welded at the outer periphery to the urea solution tank 20.
That is, the welding flange portion 124 may be integrally bent from the fill port 122 to be perpendicular to the fill port 122.
The support portion 125 integrally protrudes upward at the top of the welding flange portion 124 to correspond to the connection portion 116 of the cover body 110. The inner circumference of the support portion 125 may contact the outer side of the bottom of the connection portion 116.
That is, when the cover body 110 is mounted on the vehicle body 10, a predetermined portion of the bottom of the connecting portion 116 is inserted into the supporting portion 125.
In the welding flange portion 124 configured as above, one or more discharge holes communicating with the urea solution tank 20 are formed at positions spaced apart from each other in the circumferential direction, thereby discharging the urea solution and the gas generated from the urea solution.
The discharge hole may include a first discharge hole 126 that is adjacent to the filling port 122 and communicates with the check chamber 132, and a second discharge hole 127 that is formed to correspond to the diaphragm 133 at a position spaced apart from the filling port 122 in the radial direction.
The first exhaust port 126 exhausts the urea solution or urea solution gas from the urea solution tank 20 to the outside of the urea solution tank 20. Further, the second exhaust port 127 may exhaust the urea solution gas to the outside of the urea solution tank 20.
Meanwhile, in this exemplary embodiment, one or more communication holes 128 may be formed in the support portion 125 in a circumferential direction to correspond to the first discharge hole 126 and the second discharge hole 127 so as to communicate with the outside.
The plurality of communication holes 128 may be formed to be spaced apart from each other at predetermined intervals along the circumference of the support portion 125. Therefore, the urea solution or the urea solution gas discharged from the first discharge hole 126 and the second discharge hole 127 can be discharged to the outside of the fill pipe body 120 through the communication hole 128.
That is, the communication hole 128 discharges the urea solution or the urea solution gas from the bottom of the vehicle body 10 to the outside to prevent the urea solution or the urea solution gas discharged from the first discharge hole 126 and the second discharge hole 127 from flowing into the inside of the vehicle.
In this exemplary embodiment, the filler neck 131 integrally extends downward from the bottom of the welding flange portion 124 to be placed in the urea solution tank 20.
A check chamber 132 is formed between the welding flange portions 124 above the filler neck 131 to prevent the urea solution from being splashed back from the urea solution tank 20 when the urea solution is injected.
In addition, a diaphragm 133 is provided inside between the welding flange portion 124 and the check chamber 132. The diaphragm 133 may have an annular shape.
The diaphragm 133 configured as above can prevent vibration generated from the urea solution tank 20 while running from being transmitted to the vehicle body 10.
In this exemplary embodiment, an opening and closing cover 140 is mounted on the fill port 122 of the fill pipe body 120 at the top of the through-hole 112. The opening and closing cover 140 can selectively open and close the through-hole 112 and the filling hole 121 of the filling port 122.
That is, when the urea solution is injected into the urea solution tank 20, the opening/closing cover 140 is removed from the filling port 122 and the filling port 121 is opened together with the through hole 112.
In addition, a sealing member 150 is mounted on the fill port 122 in a space formed between the connecting portion 116 and the fill port 122. The sealing member 150 may prevent the urea solution leaked from the urea solution tank 20 from flowing into the interior of the vehicle.
Here, the outer circumference of the top of the sealing member 150 contacts the inside of the top of the connection portion 116. Further, the inner periphery of the bottom of the sealing member 150 can contact the outside of the bottom of the fill port 122. The sealing member 150 may be made of rubber.
In this exemplary embodiment, a support protrusion 129 protruding upward between the first discharge hole 126 and the second discharge hole 127 may be integrally formed at the top of the welding flange part 124.
The support protrusion 129 has a triangular sectional shape and is formed around the fill port 122 in the circumferential direction.
Here, at the bottom of the opening and closing cover 140, when the opening and closing cover 140 is mounted on the fill port 122, a pressing portion 142 may be formed to correspond to the support protrusion 129, thereby closely attaching the inside of the bottom of the sealing member 150 to the support protrusion 129.
The pressing part 142 closely attaches the sealing member 150 to the support protrusion 129 to prevent the urea solution or the urea solution gas from being discharged to the outside of the urea solution tank 20 through the first discharge hole 126.
Meanwhile, in this exemplary embodiment, a secondary sealing member 160 may be installed on the top of the support portion 125 to prevent the urea solution from leaking between the connection portion 116 and the fill pipe body 120.
The cross-section of the secondary sealing member 160 has an inverted "U" shape. The secondary sealing member 160 may be made of rubber.
Therefore, the space between the connecting portion 116 and the supporting portion 125 is sealed by the sub-sealing member 160 to prevent the urea solution from leaking between the fill pipe body 120 connected to the cover body 110.
Hereinafter, the operation and function of the urea solution filler pipe apparatus 100 constructed as above according to the exemplary embodiment of the present invention will be described in detail.
Fig. 4 and 5 are schematic views showing the state of use of the urea solution filler pipe device according to the exemplary embodiment of the present invention.
First, referring to fig. 4, when the urea solution is not injected into the urea solution tank 20, the opening and closing cover 140 remains mounted on the filling port 122 at the top of the through-hole 112.
Thus, the through-hole 112 and the injection hole 121 are closed. Meanwhile, the pressing portion 142 of the opening and closing cover 140 closely attaches the sealing member 150 to the support protrusion 129 to close the first discharge hole 126.
Then, the urea solution gas generated in the urea solution tank 20 is discharged through the second discharge hole 127, and smoothly discharged to the outside through the communication hole 128 without flowing into the inside of the vehicle.
Here, when the urea solution tank 20 is shaken by the generated vibration while the vehicle is being driven, the diaphragm 133 prevents the urea solution flowing due to the shaking of the urea solution tank 20 from being discharged to the second discharge port 127. Further, the diaphragm 133 absorbs the vibration of the urea solution tank 20 to prevent the vibration from being transmitted to the vehicle body 10.
On the other hand, when the urea solution is injected into the urea solution tank 20, the operator removes the opening/closing cover 140 from the fill inlet 122 as shown in fig. 5.
Then, the through-hole 112 and the injection hole 121 are opened. Meanwhile, the first discharge hole 126 is opened together with the second discharge hole 127.
In this state, the urea solution replenishing gun 170 is inserted into the filling hole 121 of the filling port 122, and the urea solution is filled into the urea solution tank 20 from the top portion spaced apart from the filling neck 131.
In this case, when the urea solution is splashed back from the urea solution tank 20, the urea solution splashed back through the extension space in which the check chamber 132 is formed can be prevented from being discharged to the fill port 122.
Meanwhile, when the urea solution is injected, the urea solution gas or the urea solution generated in the urea solution tank 20 is discharged through the opened first and second discharge holes 126 and 127, and is smoothly discharged to the outside through the communication hole 128 without flowing into the inside of the vehicle.
Therefore, when the urea solution filler pipe apparatus 100 according to the exemplary embodiment of the present invention configured as above is applied, the urea solution filler pipe apparatus 100 is mounted on the floor of the vehicle body 10 to be directly connected with the urea solution tank 20 disposed under the vehicle body 10, thereby improving maintainability, and the connection pipe is removed to simplify the layout and reduce the manufacturing cost.
In addition, the urea solution directly flows into the urea solution tank 20 by removing the connection pipe to shorten the urea solution filling time, and when the urea solution is splashed back, the urea solution is discharged to the outside of the vehicle body 10, thereby improving and maintaining the cleanliness of the urea solution filling pipe apparatus 100.
In addition, the odor generated from the urea solution and the urea solution gas from the urea solution tank 20 is prevented from flowing into the interior of the vehicle, thereby improving the freshness of the interior of the vehicle.
Also, the diaphragm 133 is provided in the vehicle to absorb vibration of the vehicle body, thereby improving ride comfort.
While the invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
