Gas branch pipe 42.Multiple sub- urea boxes 1 by breathe freely pipeline 4 be discharged urea liquid it is filling when inside air, in order to ensure sub- urine
Air hole 7 is opened in the top of every sub- urea box 1 by the consistency of 1 preparation structure of plain case, and pipeline 4 of breathing freely includes ventilative master
Pipe 41 and ventilative branch pipe 42, branch pipe 42 of each breathing freely are directly connected to air hole 7, pass through each branch of breathing freely of 41 connection of ventilative supervisor
Air in each sub- urea box 1 is introduced into peak and the discharge of ventilative supervisor 41 by ventilative supervisor 41, breathed freely by pipe 42
Supervisor 41 arranges along the stacking direction of sub- urea box, its interior liquid is avoided to pour into the discharge for influencing air.
As shown in Fig. 4-Fig. 8, Fig. 4 is urea case lid structure partial structural schematic diagram in Fig. 1；Fig. 5 is the knot of ventilative pipeline
Structure schematic diagram；Fig. 6 is the structural schematic diagram of ventilative tube socket；Fig. 7 is the structural schematic diagram of drain line；Fig. 8 is connection tube socket
Structural schematic diagram
In one specific embodiment of this case, it is provided with and adds on the air hole 7 at the top of multiple sub- urea boxes of arranged stacked
Fill the urea case lid 8 of urea.Set air hole 7 to the filling hole of urea liquid simultaneously, by urea case lid 8 to air hole 7 into
Row capping and urea install additional.The installation site of urea case lid 8 is that multiple sub- urea boxes 1 of stacking are located at the sub- urea box of top
Air hole on 1.
In one specific embodiment of this case, the ventilative tube socket 9 of threaded connection is provided on air hole 7, it is same on tube socket 9 of breathing freely
Axis is extended with the ventilative pipe connected pipe 91 being connected to ventilative branch pipe.Air hole 7 opens up the top with sub- urea box 1, molten in urea
After liquid is filling, the leakproofness of 7 position of each air hole on sub- urea box 1 should ensure that.Pass through ventilative tube socket 9 and 7 screw thread of air hole
Connection is connected to by ventilative hole seat 9 with ventilative branch pipe 42, and the ventilative pipe connected pipe 91 of coaxial arrangement, is easy to implement on tube socket 9 of breathing freely
The connection of air pipe 4.
In one specific embodiment of this case, the bottom of every sub- urea box 1 offers urea intercommunicating pore 10, drain line
5 include the drain branch pipe 52 that drain is responsible for 51 and is connected to urea intercommunicating pore 10；It is threaded on urea intercommunicating pore 10 and drain
The connection tube socket 11 that branch pipe 52 is connected to.Drain line 5 is used to, by the urea liquid in each sub- urea box 1, be introduced into stacking knot
The sub- urea box 1 of bottommost is discharged in structure, and the bottom of every sub- urea box 1 is opened up urea intercommunicating pore 10, drain line 5 is set
It sets including drain branch pipe 52 and drain supervisor 51, drain branch pipe 52 is connected to urea intercommunicating pore 10 to incite somebody to action in single sub- urea box 1
Urea liquid draw, urea liquid is imported into the sub- urea box of bottommost by the 51 each drain branch pipes 52 of connection of drain supervisor
1, ensure that the urea liquid in urea box assembly can smoothly be discharged.
The top of each sub- urea box 1 is connected to by the way that pipeline 4 of breathing freely is arranged, when filling urea liquid, urea liquid is logical
It crosses to flow into from top to bottom communicating pipe and does not fill the sub- urea box 1 of the full bottom, air is flowed out by ventilative pipeline 4, and completion filled
Journey ensures in urea liquid installation process that air is smoothly discharged in each sub- urea box 1.It is connected to by the way that drain branch pipe 52 is arranged
Urea intercommunicating pore 10 so that the sub- urea box 1 with independent urea accommodating cavity is communicated as one, in urea liquid installation process
In, urea liquid flows into the sub- urea box 1 of bottommost first, successively rises after filling full bottom, until all sub- urea boxes are filled out
It charges, that is, completes the filling of urea liquid in all sub- urea boxes.When urea pump work, when drawing urea, due to drain pipe
The effect of road 5 and ventilative pipeline 4 is, it can be achieved that the top-down smooth suction of urea liquid.
In one specific embodiment of this case, limit deep gouge 2 includes respectively along the transverse direction of sub- urea box and vertical arranged crosswise
Horizontal limit deep gouge and perpendicular limit deep gouge；Positive stop lug boss 3 is the cross positive stop lug boss for protruding from sub- urea box bottom.Limit is heavy
Slot 2 is located at the middle part at 1 top of sub- urea box, is in crosswise structure, and accordingly, positive stop lug boss 3 is cross positive stop lug boss, limit
It needs to ensure fitting gap between deep gouge 2 and positive stop lug boss 3, avoids urea box assembly with the shaking of car body.
Since limit deep gouge 2 includes the horizontal limit deep gouge of right-angled intersection and perpendicular limit deep gouge, with horizontal limit deep gouge and perpendicular limit
Position deep gouge is reference axis, therefore sub- urea box 1 is in boss structure in four quadrants, and accordingly, sub- urea box 1 is in filling urea
When, it is located at the sub- urea box of multiple 1 tops of sub- urea box of arranged stacked, it will cannot complete filling full area there are four
Domain adapts to the variation of vehicle operation hot-cool environment, and the limit deep gouge structure of the right-angled intersection of sub- urea box is that urea box assembly is pre-
The space expanded with heat and contract with cold is stayed, safety is improved.
In one specific embodiment of this case, the top of every sub- urea box 1 offers urea box sensor mounting base 12,
It further include the connection wiring harness 13 being connected to each urea box sensor mounting base 12；
Connection wiring harness 13 includes that the sub- urea box 1 of bottommost in multiple sub- urea boxes 1 to stacking carries out monitoring temperature
Liquid level and temperature sensor, and the liquid level sensor of liquid level monitoring is carried out to its minor urea box.
Vehicle houses urea liquid by urea box assembly, in vehicle operation, needs to monitor urea temperature and urine constantly
Plain surplus.Due to the stepped construction that urea box assembly is multiple sub- urea boxes 1, in specific monitoring, it is only necessary to monitoring most bottom
Urea temperature in the sub- urea box 1 in portion, and due to being back to urea box assembly inside information condition there are urea during urea use,
Therefore it needs the liquid level to every sub- urea box to be monitored, is monitored with the total amount to urea.
Urea box sensor mounting base is preset on sub- urea box 1, being connected to each urea box sensor by connection wiring harness 13 pacifies
Seat 12 is filled, each sensor is monitored urea liquid state in sub- urea box 1 by urea box sensor mounting base 12.It is suitable
The working condition of the urea box assembly of arranged stacked is answered, is set as liquid level and temperature sensor in the sub- urea box of bottommost, in real time
Monitor the operating temperature and liquid level of its interior urea, liquid level sensor in minor urea box, only to urea level in sub- urea box
It is monitored.Pipe screw thread form can be used in urea box sensor, realizes effectively sealing.Each urea box sensor passes through connecting line
Beam is connected in series with, and realizes the liquid level monitoring to entire urea box assembly.
In one specific embodiment of this case, the bottom of every sub- urea box 1 is additionally provided with taphole 14, is connected to liquid back pipe
Liquid back pipe interface 16, and with pipette connect imbibition interface tube 15.The work for adapting to urea box assembly in vehicle operation is wanted
It asks, taphole 14 is arranged in the bottom of every sub- urea box 1, wherein the taphole being only arranged in the sub- urea box 1 of bottommost
Tapping is arranged to switch, remaining taphole is bolt enclosed construction.The upper setting liquid back pipe interface and lotion pipeline of every sub- urea box
Interface is connected with liquid back pipe and pipette respectively, realizes the requirement different to urea.
The structure of urea box assembly provided in this embodiment, every sub- urea box 1 is consistent, using identical mold manufacturing,
Die cost has a clear superiority compared to same volume urea box；And small size urea babinet structural strength higher, it is less variable
