Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a urea filling device, a urea filling system, and a vehicle. Background Technology

[0002] The urea tank is a core component of the exhaust aftertreatment system of a tractor unit. It stores automotive urea, which reacts with nitrogen oxides in the exhaust gas to produce nitrogen and water, thus reducing exhaust pollution.

[0003] In related technologies, the urea tank needs to be located in a position with minimal obstruction and easy access for personnel to add urea. However, the flexibility in the urea tank's location is limited. The urea tank is relatively large, and its location significantly impacts the overall vehicle layout. The limited flexibility in the urea tank's location can lead to a limited flexibility in the overall vehicle layout, resulting in greater design complexity. Utility Model Content

[0004] This application provides a urea filling device, a urea filling system, and a vehicle, which can reduce the design difficulty of the overall vehicle layout.

[0005] In a first aspect, this application provides a urea filling device for use in vehicles. The urea filling device includes a filling cup, a base, a filling pipe, and a vent pipe. The base is used to connect with the filling port of the urea tank. The upper end of the filling pipe is connected to the filling cup, and the lower end of the filling pipe is connected to the base. The upper end of the vent pipe is connected to the filling cup, and the lower end of the vent pipe is connected to the base.

[0006] The urea filling device provided in this application features a separate filling cup and urea tank design. The filling cup and urea tank are connected via a filling pipe and a base. Personnel can fill the filling cup with urea, which then flows through the filling pipe and base into the urea tank. Compared to integrating the filling cup into the urea tank, the urea tank in this application offers greater flexibility in placement. Even if the urea tank is placed in a concealed location that is difficult for personnel to access, personnel can still fill the urea tank using the filling cup, making the filling process relatively convenient. Compared to the urea tank, the filling cup is smaller in size, has less impact on the overall vehicle layout, and can be easily placed in a location easily accessible to personnel. Therefore, the greater flexibility in the placement of the urea tank in this application leads to greater flexibility in the overall vehicle layout, reducing the design complexity of the vehicle layout.

[0007] Furthermore, in this application, the urea filling device also includes a vent pipe. The filling cup is connected to the urea tank through the vent pipe and the base. This allows the gas in the urea tank to flow sequentially through the base and the vent pipe to the urea cup and then be discharged into the external environment through the urea cup. This makes it less likely for the gas pressure in the urea tank to fluctuate significantly, ensuring that the process of urea entering the urea tank proceeds smoothly with minimal obstruction.

[0008] Furthermore, in this application, the base is connected to the filling port of the urea tank, and both the vent pipe and the filling pipe are connected to the urea tank through the base. Compared to the case where the vent pipe and the filling pipe are directly connected to the urea tank, this application can utilize a mature urea tank. The base and the urea tank are of a separate structure, and the base can be connected to the filling port of a mature urea tank. This application does not require major structural modifications to the mature urea tank, which helps to reduce costs.

[0009] In some possible implementations of this application, the base includes a base plate, a first connecting pipe, and a second connecting pipe. The base plate is used to connect with the filling port of the urea tank. The lower ends of the first and second connecting pipes both penetrate the base plate. The lower end of the filling pipe is fixedly connected to the upper end of the first connecting pipe to communicate with the base through the first connecting pipe. The lower end of the vent pipe is fixedly connected to the upper end of the second connecting pipe to communicate with the base through the second connecting pipe.

[0010] In this way, both the first and second connecting pipes are installed at the filling port of the urea tank through the base plate. The base plate has a simple shape, consumes less material, and matches the shape of the filling port well. It can effectively seal the filling port, so that during the urea filling process, the urea in the urea tank is less likely to splash into the external environment through the gap between the filling port and the base. It also allows the gas in the urea tank to enter the vent pipe through the base as much as possible, rather than entering the external environment through the gap between the filling port and the base. In addition, the outer surface of the base plate is flat, which facilitates a large contact area between the base plate and the urea tank and the contact is relatively tight, which helps to form a more stable connection between the base plate and the urea tank.

[0011] Furthermore, the lower ends of both the first and second connecting pipes penetrate the base plate. The filling pipe and the vent pipe are connected to the urea tank through the first and second connecting pipes, respectively. Compared to the case where the filling pipe and the vent pipe are directly connected to the through holes in the base plate, the base plate in this application can be made relatively thin, which helps reduce material consumption. It is understandable that if through holes are made in the base plate, the base plate needs to be made thicker to ensure sufficient strength and rigidity.

[0012] In some possible implementations of this application, the first connecting pipe is gradually inclined from top to bottom, the second connecting pipe is vertically arranged, the lower edge of the second connecting pipe is lower than the lower edge of the first connecting pipe, and the vertical distance between the lower edge of the second connecting pipe and the lower edge of the first connecting pipe is not less than 10mm.

[0013] By gradually tilting the first connecting pipe from top to bottom, the angle between the extension direction of the first connecting pipe and the direction from the filling port to the filling cup is smaller. This helps to reduce the degree of bending of the filling pipe connecting the filling cup and the first connecting pipe, thereby improving the smoothness of urea flow in the filling pipe.

[0014] In addition, by making the lower edge of the second connecting pipe lower than the lower edge of the first connecting pipe, as urea is added to the urea tank and the liquid level in the urea tank gradually rises, the liquid level first covers the lower edge of the second connecting pipe. After the liquid level covers the lower edge of the second connecting pipe, the gas in the urea tank is difficult to escape through the second connecting pipe. This causes the gas pressure in the urea tank to gradually increase as urea is added, thus greatly hindering the process of urea entering the urea tank. This can reduce the risk of excessive urea being injected into the urea tank, leading to urea overflow.

[0015] By ensuring that the vertical distance between the lower edge of the second connecting pipe and the lower edge of the first connecting pipe is no less than 10mm, on the one hand, the liquid level needs to rise at least 10mm after submerging the lower edge of the second connecting pipe to reach the lower edge of the first connecting pipe, providing sufficient margin and reducing the risk of urea overflowing from the urea tank. On the other hand, by making the distance between the lower edge of the second connecting pipe and the lower edge of the first connecting pipe larger, the urea liquid flow entering the urea tank through the first connecting pipe is less likely to obstruct the lower opening of the second connecting pipe, which facilitates the smooth passage of air through the lower opening of the second connecting pipe into the second connecting pipe and into the filling cup.

[0016] By setting the second connecting pipe vertically, its vertical length is less affected by horizontal space constraints, allowing its lower edge to be positioned lower and thus preventing urea from easily overflowing the urea tank. Conversely, if the second connecting pipe were angled, its vertical length would be limited by horizontal space, making it difficult to set it long enough. This would result in the lower edge of the second connecting pipe being closer to the lower edge of the first connecting pipe, leading to urea overflowing the urea tank more easily.

[0017] Secondly, this application provides a urea dispensing system, which includes a urea tank, a mounting bracket, and the urea dispensing device provided in the first aspect of this application. The urea tank has a dispensing port, a base is connected to the dispensing port, the mounting bracket is used for fixed connection with an intake pipe bracket, and the mounting bracket is also fixedly connected to a dispensing cup.

[0018] The urea filling system provided in this application, including the urea filling device provided in the first aspect of this application, can achieve the same technical effects as the urea filling device, namely, it can reduce the design difficulty of the overall vehicle layout, improve the smoothness of urea entering the urea tank, and utilize a mature urea tank, which is conducive to cost reduction. In addition, the urea filling system provided in this application also includes a mounting bracket, which is fixed between the intake pipe bracket and the filling cup, which helps to improve the stability of the filling cup installation. Moreover, the intake pipe bracket is used to support the intake pipe on the one hand, and the mounting bracket on the other hand, thereby supporting the filling cup. The intake pipe bracket is fully utilized, and the vehicle does not need to be equipped with other components for supporting the mounting bracket, which helps to improve the compactness of the structure.

[0019] In some possible implementations of this application, the mounting bracket includes a first plate portion, the thickness direction of the first plate portion being the same as the length direction of the vehicle, the upper edge of the first plate portion being bent toward the rear of the vehicle to form a second plate portion, the filling cup being inserted through the second plate portion and fixedly connected to the second plate portion, and the lower edge of the first plate portion being bent toward the front of the vehicle to form a third plate portion, the third plate portion being used for fixed connection with the intake pipe bracket.

[0020] By aligning the thickness of the first plate with the length of the vehicle, its shape closely matches the rear sidewall of the cab. This allows for a more compact arrangement of the second plate and the cab, improving space utilization. The upper edge of the second plate bends towards the rear of the vehicle, providing sufficient length for the refueling cup. The refueling cup passes through the second plate, ensuring a secure and convenient connection. Located above the first plate, the higher position of the second plate also elevates the refueling cup, facilitating easy access and refueling. Furthermore, both the second and third plates are formed from the bent edges of the first plate, allowing the mounting bracket to be formed from bent sheet metal, simplifying manufacturing and reducing costs.

[0021] In some possible implementations of this application, the upper side of the third plate is used to abut against the intake pipe bracket, and the front side of the third plate is provided with a clearance notch corresponding to the intake pipe.

[0022] By having the upper side of the third plate abut against the intake pipe bracket, a larger contact area between the third plate and the intake pipe bracket is achieved, which improves the stability of the third plate installation. By providing a clearance notch on the front side of the third plate corresponding to the intake pipe, interference between the third plate and the intake pipe is minimized. The clearance notch also allows for clearance of components such as the dust bag from the intake pipe, and the third plate can be fitted more compactly with the lower side of the intake pipe.

[0023] Thirdly, this application provides a vehicle, which includes an air intake pipe, an air intake pipe bracket, and a urea filling system provided in the second aspect of this application. The air intake pipe is located at the rear of the cab and at the front of the mounting bracket. The air intake pipe is fixedly connected to the air intake pipe bracket, and the air intake pipe bracket is fixedly connected to the vehicle frame.

[0024] The vehicle provided in this application, including the urea filling system provided in the second aspect of this application, can achieve the same technical effect as the urea filling system, namely, it can reduce the design difficulty of the overall vehicle layout, improve the smoothness of urea entering the urea tank, and utilize mature urea tanks, which is conducive to reducing costs.

[0025] In some possible implementations of this application, the mounting bracket includes a first plate portion, the thickness direction of which is the same as the length direction of the vehicle. The lower edge of the first plate portion is bent forward towards the vehicle to form a third plate portion, which is fixedly connected to the intake pipe bracket. The intake pipe bracket includes a fourth plate portion, the lower side of the third plate portion and the intake pipe are both disposed opposite to the fourth plate portion, the fourth plate portion is fixedly connected to the third plate portion, and the fourth plate portion abuts against the lower side of the intake pipe.

[0026] By including a fourth plate portion in the intake pipe bracket, with the fourth plate portion positioned opposite to and fixedly connected to the third plate portion, the intake pipe bracket and the third plate portion have a larger connection area, which improves the stability of the connection. Furthermore, by having the fourth plate portion abut against the lower side of the intake pipe, the contact area between the fourth plate portion and the lower side of the intake pipe is also large, which improves the stability of the intake pipe bracket's support for the intake pipe.

[0027] In some possible implementations of this application, the vehicle further includes at least one of a rear suspension bracket and a front axle suspension bracket. One end of the fourth plate is bent downward to form a fifth plate, and the lower end of the fifth plate is bent horizontally to form a sixth plate. The lower side of the sixth plate abuts against at least one of the rear suspension bracket and the front axle suspension bracket, and the sixth plate is fixedly connected to the vehicle frame via at least one of the rear suspension bracket and the front axle suspension bracket.

[0028] By bending one end of the fourth plate downwards to form the fifth plate, and bending the lower end of the fifth plate horizontally to form the sixth plate, the manufacturing of the intake manifold bracket is made more convenient, as the intake manifold bracket can be formed by bending sheet metal. By having the lower side of the sixth plate abut against at least one of the rear suspension bracket and the front axle suspension bracket, the connection area between at least one of the rear suspension bracket and the front axle suspension bracket and the intake manifold bracket is larger, which helps to improve the stability of the intake manifold bracket mounted on the vehicle frame.

[0029] In some possible implementations of this application, a fifth plate is formed at the front end of the fourth plate, the fifth plate extends along the width direction of the vehicle, one end of the fifth plate is connected to the fourth plate, and the other end is connected to the sixth plate.

[0030] Generally, in the vehicle width direction, there is a certain distance between the intake pipe and the rear suspension bracket, and also a certain distance between the intake pipe and the front axle suspension bracket. By extending the fifth plate portion along the vehicle width direction, the fifth plate portion can connect the fourth plate portion at the intake pipe, as well as the sixth plate portions at the rear and front axle suspension brackets. By forming the fifth plate portion at the front end of the fourth plate portion, the connection length between the fifth and fourth plate portions, and between the fifth and sixth plate portions, are both larger in the vehicle width direction, which helps to improve the reliability of the intake pipe bracket.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 This application provides a vehicle that includes a urea filling system. The urea filling system includes a urea tank 4 and a urea filling device 3. The urea filling device 3 includes a filling cup 31, a base 36, a filling pipe 32, and a vent pipe. The base 36 is connected to the filling port of the urea tank 4. The upper end of the filling pipe 32 is connected to the filling cup 31, and the lower end of the filling pipe 32 is connected to the base 36. The upper end of the vent pipe is connected to the filling cup 31, and the lower end of the vent pipe is connected to the base 36.

[0041] The urea filling device 3 provided in this embodiment features a separate filling cup 31 and urea tank 4. The filling cup 31 and urea tank 4 are connected via a filling pipe 32 and a base 36. Personnel can fill the filling cup 31 with urea, which then flows through the filling pipe 32 and base 36 into the urea tank 4. Compared to integrating the filling cup 31 into the urea tank 4, this embodiment offers greater flexibility in the placement of the urea tank 4. Even if the urea tank 4 is placed in a concealed location that is difficult for personnel to access, personnel can still fill the urea tank using the filling cup 31, making the filling process relatively convenient. Compared to the urea tank 4, the filling cup 31 is smaller in size, has less impact on the overall vehicle layout, and can be easily placed in a location easily accessible to personnel. Therefore, the greater flexibility in the placement of the urea tank 4 in this embodiment leads to greater flexibility in the overall vehicle layout, reducing the design complexity of the vehicle layout.

[0042] Furthermore, in this embodiment of the application, the urea filling device 3 also includes a vent pipe. The filling cup 31 is connected to the urea tank 4 through the vent pipe and the base 36. This allows the gas in the urea tank 4 to flow sequentially through the base 36 and the vent pipe to the urea cup and then be discharged into the external environment through the urea cup. This makes it less likely for the gas pressure in the urea tank 4 to fluctuate significantly, ensuring that the process of urea entering the urea tank 4 proceeds smoothly with minimal obstruction.

[0043] Furthermore, in this embodiment, the base 36 is connected to the filling port of the urea tank 4, and both the vent pipe and the filling pipe 32 are connected to the urea tank 4 through the base 36. Compared to the direct connection of the vent pipe and the filling pipe 32 to the urea tank 4, this embodiment can utilize a mature urea tank 4. The base 36 and the urea tank 4 are separate structures, and the base 36 can be connected to the filling port of the mature urea tank 4 without requiring significant structural modifications to the mature urea tank 4, which helps to reduce costs.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment of the application, the filling cup 31 has a cup opening, through which personnel can add urea into the filling cup 31. For example, the cup opening can be connected to the filling gun. A magnetic component for connecting with the filling gun can be provided inside the filling cup 31. When the filling gun is attracted to the magnetic component, the filling gun adds urea into the filling cup 31. Alternatively, personnel can pour urea from the urea tank into the filling cup 31 through the cup opening.

[0045] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the dispensing assembly further includes a cup lid 35, which is detachably disposed on the cup opening. In this way, the cup lid 35 can seal the dispensing port to reduce the risk of impurities from the environment entering the dispensing cup 31. When urea needs to be dispensed, the cup lid 35 can be opened.

[0046] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, a urea inlet is formed on the surface of the filling cup 31 away from the cup opening along the axial direction of the filling cup 31. The urea inlet connects the inside and outside of the filling cup 31, and the filling pipe 32 connects the urea inlet to the base 36. In this way, urea flows smoothly within the filling cup 31 along its axial direction. It should be noted that the axial direction of the filling cup 31 is parallel to the orientation of the cup opening.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the filling cup 31 includes a cup body 311 and a first tube 312. The cup opening is formed in the cup body 311, and the axial direction of the first tube 312 may be the same as the axial direction of the cup body 311. One end of the first tube 312 is connected to the end of the cup body 311 away from the cup opening, and the other end of the first tube 312 forms a urea port. The first tube 312 can be connected to the filling pipe 32 by a clamp 34. In this way, the connection between the filling cup 31 and the filling pipe 32 is stable and convenient.

[0048] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the filling cup 31 includes a cup body 311 and a second tube 313. The axial direction of the second tube 313 may be the same as that of the cup body 311. One end of the second tube 313 is connected to the end of the cup body 311 away from the cup opening, and the other end of the second tube 313 forms a vent. The second tube 313 can be connected to the exhaust pipe 33 by a clamp 34. In this way, the connection between the filling cup 31 and the exhaust pipe 33 is stable and convenient.

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the filling pipe 32 may be made of flexible rubber material. Flexible rubber material is resistant to urea corrosion, can be bent to adapt to complex environments, and can absorb vibrations generated during vehicle operation. In some embodiments of this application, the exhaust pipe 33 may be made of flexible rubber material.

[0050] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the base 36 can be made of a urea-resistant material, such as plastic or stainless steel, which can improve the reliability of the base 36.

[0051] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments of this application, the base 36 includes a base plate 361, a first connecting pipe 362, and a second connecting pipe 363. The base plate 361 is used to connect with the filling port of the urea tank 4. The lower ends of the first connecting pipe 362 and the second connecting pipe 363 both penetrate the base plate 361. The lower end of the filling pipe 32 is fixedly connected to the upper end of the first connecting pipe 362 to communicate with the base 36 through the first connecting pipe 362. The lower end of the vent pipe is fixedly connected to the upper end of the second connecting pipe 363 to communicate with the base 36 through the second connecting pipe 363.

[0052] In this way, both the first connecting pipe 362 and the second connecting pipe 363 are installed at the filling port of the urea tank 4 through the base plate 361. The base plate 361 has a simple shape, consumes less material, and has a high degree of matching with the shape of the filling port, which can effectively seal the filling port. This makes it difficult for the urea in the urea tank 4 to splash into the external environment through the gap between the filling port and the base 36 during the urea filling process. It also allows the gas in the urea tank 4 to enter the vent pipe through the base 36 as much as possible, rather than entering the external environment through the gap between the filling port and the base 36. Moreover, the outer surface of the base plate 361 is flat, which facilitates a large contact area between the base plate 361 and the urea tank 4 and a relatively tight contact, which is conducive to forming a more stable connection between the base plate 361 and the urea tank 4.

[0053] Furthermore, the lower ends of both the first connecting pipe 362 and the second connecting pipe 363 penetrate the base plate 361. The filling pipe 32 and the vent pipe are connected to the urea tank 4 through the first connecting pipe 362 and the second connecting pipe 363, respectively. Compared to the embodiment where the filling pipe 32 and the vent pipe are directly connected to the through holes on the base plate 361, the base plate 361 in this application embodiment can be made relatively thin, which is beneficial to reducing material consumption. It is understood that, since the base plate 361 has through holes, it needs to be made relatively thick in order to give the base plate 361 sufficient strength and rigidity.

[0054] Please refer to Figure 1 , Figure 4 and Figure 5 In this embodiment of the application, the base plate 361 and the urea tank 4 can be fastened together, and the fasteners connected between the base plate 361 and the urea tank 4 can be arranged circumferentially along the opening.

[0055] Please refer to Figure 2 , Figure 4 and Figure 5 In some embodiments of this application, the urea tank 4 includes a tank body 41 and a mounting member 42. The mounting member 42 passes through the tank wall of the tank body 41 and is fixedly connected to the tank body 41. The mounting member 42 has a filling port that connects the inside and outside of the tank body 41. The bottom plate 361 is fastened to the mounting member 42. In this way, the length of the mounting member 42 along the axial direction of the opening is relatively large, which makes the bottom plate 361 and the mounting member 42 fastened together, which helps to improve the stability of the installation of the bottom plate 361.

[0056] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of this application, the first connecting pipe 362 is gradually inclined from top to bottom, the second connecting pipe 363 is vertically arranged, the lower edge of the second connecting pipe 363 is lower than the lower edge of the first connecting pipe 362, and the vertical distance between the lower edge of the second connecting pipe 363 and the lower edge of the first connecting pipe 362 is not less than 10mm.

[0057] By gradually tilting the first connecting pipe 362 from top to bottom, the angle between the extension direction of the first connecting pipe 362 and the direction from the filling port to the filling cup 31 is smaller. This helps to reduce the degree of bending of the filling pipe 32 connecting the filling cup 31 and the first connecting pipe 362, thereby improving the smoothness of urea flow in the filling pipe 32.

[0058] In addition, by making the lower edge of the second connecting pipe 363 lower than the lower edge of the first connecting pipe 362, during the process of adding urea to the urea tank 4 and the liquid level in the urea tank 4 gradually rising, the liquid level first submerges the lower edge of the second connecting pipe 363. After the liquid level submerges the lower edge of the second connecting pipe 363, the gas in the urea tank 4 is difficult to escape through the second connecting pipe 363. This causes the gas pressure in the urea tank 4 to gradually increase as urea is added, thus greatly hindering the process of urea entering the urea tank 4. This can reduce the risk of excessive urea being injected into the urea tank 4, leading to urea overflow.

[0059] By ensuring that the vertical distance between the lower edge of the second connecting pipe 363 and the lower edge of the first connecting pipe 362 is not less than 10mm, on the one hand, the liquid level needs to rise at least 10mm after submerging the lower edge of the second connecting pipe 363 to reach the lower edge of the first connecting pipe 362, providing sufficient margin and reducing the risk of urea overflowing from the urea tank 4. On the other hand, by ensuring a larger distance between the lower edge of the second connecting pipe 363 and the lower edge of the first connecting pipe 362, the urea liquid flow entering the urea tank 4 through the first connecting pipe 362 is less likely to obstruct the lower opening of the second connecting pipe 363, which facilitates the smooth passage of air through the lower opening of the second connecting pipe 363 into the second connecting pipe 363 and into the filling cup 31.

[0060] By making the second connecting pipe 363 vertical, the length of the second connecting pipe 363 in the vertical direction z is less affected by the horizontal space, allowing the lower edge of the second connecting pipe 363 to be set lower, thus making it less likely for urea to overflow from the urea tank 4. It is understandable that if the second connecting pipe 363 is set at an angle, the longer its length in the vertical direction z, the longer its length in the horizontal direction. Since the length of the second connecting pipe 363 in the vertical direction z is limited by the horizontal space, it is difficult to make the second connecting pipe 363 long enough, resulting in a closer vertical distance between the lower edge of the second connecting pipe 363 and the lower edge of the first connecting pipe 362, causing urea to easily overflow from the urea tank 4.

[0061] In some embodiments of this application, the lower edge of the first connecting pipe 362 has a gap with the mounting member 42. In this way, the first connecting pipe 362 is less likely to interfere with the mounting member 42, which helps to reduce damage to the first connecting pipe 362 and the mounting member 42, and also makes it less likely that the mounting member 42 will obstruct the process of air entering the first connecting pipe 362.

[0062] In some embodiments of this application, the arrangement direction of the first connecting pipe 362 and the second connecting pipe 363 may be perpendicular to the extension direction of the first connecting pipe 362. In this way, the distance between the first connecting pipe 362 and the second connecting pipe 363 is relatively large, making it less likely for the urea liquid flow to obstruct the lower end of the second connecting pipe 363, which is conducive to the smooth discharge of air.

[0063] In some embodiments of this application, the second connecting pipe 363 is perpendicular to the base plate 361. The second connecting pipe 363 spans across opposite sides of the base plate 361 along its thickness direction, making it perpendicular to the base plate 361, which facilitates the connection between the base plate 361 and the second connecting pipe 363. It is understood that tilting the second connecting pipe 363 to the base plate 361 would require machining an elliptical hole in the base plate 361 before inserting the second connecting pipe 363 into the elliptical hole. Machining the elliptical hole is difficult, and controlling the positional accuracy of the second connecting pipe 363 and the elliptical hole is very troublesome. However, in the embodiments of this application, the second connecting pipe 363 is perpendicular to the base plate 361, making it easy to control the relative positional accuracy of the second connecting pipe 363 and the base plate 361, and eliminating the need to machine an elliptical hole, thus simplifying the connection between the base plate 361 and the second connecting pipe 363.

[0064] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of this application, the axial direction of the filling port can be vertical (z), and the thickness direction of the base plate 361 is also vertical (z). This makes the manufacturing of the filling port more convenient, and allows for a tighter fit between the base plate 361 and the filling port.

[0065] Please refer to Figure 3 , Figure 4 and Figure 5 In this embodiment of the application, the extension direction of the first connecting tube 362 can be designed according to the arrangement direction of the filling port and the filling cup 31. The tilt angle of the extension direction of the first connecting tube 362 relative to the vertical direction z can be 40 to 60 degrees, such as 45 degrees, 50 degrees or 55 degrees.

[0066] Please refer to Figure 3 , Figure 4 and Figure 5In some embodiments of this application, the first connecting pipe 362 and the filling pipe 32 can be fixedly connected by a clamp 34. This makes the connection between the first connecting pipe 362 and the filling pipe 32 more stable and convenient. In some embodiments of this application, a first protrusion 3621 is formed on the outer wall of the first connecting pipe 362. The first protrusion 3621 can extend circumferentially along the first connecting pipe 362. The filling pipe 32 is sleeved on the first connecting pipe 362, with its inner wall abutting against the first protrusion 3621 and its outer wall abutting against the inner wall of the clamp 34. This helps to improve the tightness of the connection between the filling pipe 32 and the first connecting pipe 362.

[0067] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of this application, the second connecting pipe 363 and the vent pipe can be fixedly connected by a clamp 34. This makes the connection between the second connecting pipe 363 and the vent pipe more stable and convenient. In some embodiments of this application, a second protrusion is formed on the outer wall of the second connecting pipe 363. The second protrusion can extend circumferentially along the second connecting pipe 363. The vent pipe is sleeved on the second connecting pipe 363, with its inner wall abutting against the second protrusion and its outer wall abutting against the inner wall of the clamp 34. This helps to improve the tightness of the connection between the vent pipe and the second connecting pipe 363.

[0068] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments of this application, an airflow channel and a urea channel are formed inside the filling cup 31. The airflow channel and the urea channel are separated. One end of the airflow channel faces the cup opening, and the other end has a vent. The vent connects the inside and outside of the filling cup 31 and can be formed on the surface of the filling cup 31 away from the cup opening. The exhaust pipe 33 connects the vent to the base 36. During the process of filling urea into the urea tank 4 through the filling cup 31, the air in the urea tank 4 can be discharged to the external environment through the base 36, the exhaust pipe 33, and the airflow channel, so that the urea can smoothly enter the urea tank 4. When the liquid level exceeds the second connecting pipe 363, the gas is difficult to be discharged into the urea tank 4. If the filling gun detects that the discharged gas is insufficient or not discharged, the filling gun stops dispensing urea to reduce the risk of urea overflow.

[0069] Please refer to Figure 1 , Figure 3 and Figure 6In some embodiments of this application, the urea filling system further includes a mounting bracket 2, and the vehicle further includes an air intake pipe 11 and an air intake pipe bracket 26. The mounting bracket 2 is used to fixably connect to the air intake pipe bracket 26, and the filling cup 31 is fixedly connected to the mounting bracket 2. The air intake pipe 11 is located at the rear of the cab and at the front of the mounting bracket 2, and is fixedly connected to the air intake pipe bracket 26. The air intake pipe bracket 26 is fixedly connected to the vehicle frame. By fixing the mounting bracket 2 between the air intake pipe bracket 26 and the filling cup 31, the stability of the filling cup 31 is improved. Moreover, the air intake pipe bracket 26 is used to support the air intake pipe 11 on the one hand, and the mounting bracket 2 on the other hand, thereby supporting the filling cup 31. The air intake pipe bracket 26 is fully utilized, and the vehicle does not need to be equipped with other components for supporting the mounting bracket 2, which helps to improve the compactness of the structure.

[0070] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments of this application, the refueling cup 31 is located at one end of the cab along the width direction x of the vehicle. This places the refueling cup 31 in a position easily accessible to personnel. In some embodiments of this application, the refueling cup 31 is located above the vehicle frame. This also places the refueling cup 31 in a position easily accessible to personnel.

[0071] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments of this application, the vehicle further includes a fairing, which has the same meaning as commonly understood by those skilled in the art. The fairing is located behind the cab, with its thickness in the vehicle's width direction (x), and is located at one end of the cab along the thickness direction. A refueling cup 31 is located on the side of the fairing near the center of the vehicle along the thickness direction. The fairing has an opening that extends through the fairing along its thickness direction, aligning with the refueling cup 31. A refueling gun can pass through the opening and dock with the refueling cup 31. In some embodiments of this application, the vehicle also includes a baffle, which is detachably combined with the opening. This allows the baffle to block the opening, thereby protecting the refueling cup 31. The baffle is detachable from the opening, allowing the refueling gun to pass through the opening and dock with the refueling cup 31.

[0072] Please refer to Figure 1 , Figure 3 and Figure 6In some embodiments of this application, the filling cup 31 is located at one end of the cab along the width direction x of the vehicle, with the cup opening facing perpendicular to the length direction y of the vehicle and tilted upwards relative to the horizontal plane. The cup opening faces away from the other end of the vehicle along the width direction x. This positions the cup opening in a location easily accessible to personnel. After entering the filling cup 31 through the cup opening, the urea flows downwards, resulting in minimal flow resistance from the filling cup 31 to the urea tank 4.

[0073] Please refer to Figure 1 , Figure 3 and Figure 6 In some embodiments of this application, the mounting bracket 2 includes a first plate portion 22, the thickness direction of the first plate portion 22 is the same as the length direction y of the vehicle, the upper edge of the first plate portion 22 is bent toward the rear of the vehicle to form a second plate portion 21, the filling cup 31 is inserted through the second plate portion 21 and is fixedly connected to the second plate portion 21, and the lower edge of the first plate portion 22 is bent toward the front of the vehicle to form a third plate portion 24, the third plate portion 24 is used to be fixedly connected to the intake pipe bracket 26.

[0074] By aligning the thickness direction of the first plate 22 with the length direction (y) of the vehicle, the shape of the first plate 22 closely matches the rear sidewall of the cab. This allows the second plate 21 to be installed more compactly within the cab, improving space utilization. The upper edge of the second plate 21 bends towards the rear of the vehicle, forming the second plate 21. The second plate 21 has sufficient length in the length direction (y) of the vehicle, providing ample installation space for the refueling cup 31. The refueling cup 31 passes through the second plate 21, ensuring a stable and convenient connection between them. The second plate 21 is located above the first plate 22, placing it at a higher position, which also elevates the refueling cup 31, facilitating easy access and refueling operations. Furthermore, both the second plate 21 and the third plate 24 are formed from the bends at the edges of the first plate 22, allowing the mounting bracket 2 to be formed from bent sheet metal. This simplifies the manufacturing process of the mounting bracket 2 and reduces costs.

[0075] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of this application, a first reinforcing rib 222 is formed on the first plate portion 22. The first reinforcing rib 222 can be a strip-shaped stamped rib, and the extension direction of the stamped rib is perpendicular to the thickness direction of the first plate portion 22. In this way, the first plate portion 22 has high strength, and the first reinforcing rib 222 is easier to process and manufacture.

[0076] Please refer to Figure 6 , Figure 7 and Figure 8In some embodiments of this application, a second reinforcing rib 23 may be formed between the first plate portion 22 and the second plate portion 21. The second reinforcing rib 23 may be a triangular stamped rib. This makes the mounting bracket 2 more reliable and the second reinforcing rib 23 easier to manufacture.

[0077] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of this application, the axial direction of the filling cup 31 may be the same as the thickness direction of the second plate portion 21. This facilitates the installation of the filling cup 31 and the second plate portion 21.

[0078] Please refer to Figure 6 , Figure 7 and Figure 8 In this embodiment, the filling cup 31 passes through the second plate portion 21. Specifically, the second plate portion 21 has a mounting hole 211 that extends through the second plate portion 21 along its depth direction, and the filling cup 31 passes through the mounting hole 211. In some embodiments of this application, the outer wall of the filling cup 31 forms a flange 3111. The thickness direction of the flange 3111 is the same as the thickness direction of the second plate portion 21. Along the thickness direction of the second plate portion 21, the flange 3111 abuts against the second plate portion 21. A first fastener passes through the flange 3111 and the second plate portion 21 along the thickness direction of the second plate portion 21, thereby fastening the flange 3111 and the second plate portion 21 together. This makes the connection between the filling cup 31 and the second plate portion 21 more stable. The hole in the second plate portion 21 for the first fastener is shown as the connecting hole 212 in the diagram.

[0079] Please refer to Figure 6 , Figure 7 and Figure 8 In this embodiment of the application, the third plate 24 is used to be fixedly connected to the intake pipe bracket 26, and can be implemented in various ways, such as welding or fastening connection.

[0080] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of this application, a third reinforcing rib 25 may be formed between the second plate portion 21 and the third plate portion 24. The third reinforcing rib 25 may be a triangular stamped rib. This makes the mounting bracket 2 more reliable and the third reinforcing rib 25 easier to manufacture.

[0081] Please refer to Figure 6 , Figure 7 and Figure 8In some embodiments of this application, the vehicle further includes a fastener connected between the filling tube 32 and the first plate portion 22. Thus, the first plate portion 22 not only supports the filling cup 31 but also connects to the fastener to secure the filling tube 32. The first plate portion 22 is fully utilized, reducing the need for other parts used to secure the filling tube 32 and improving structural integration. Furthermore, the close proximity of the first plate portion 22 to the filling tube 32, and the connection between the fastener and the first plate portion 22, allows for a shorter fastener length, saving materials, improving space utilization, and increasing the rigidity of the fastener.

[0082] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of this application, the fixing member includes a cable tie, a binding strap, and a connector. The connector is made of a rigid material and has a first through hole and a second through hole. The cable tie passes through the first through hole and wraps around the filling tube 32, binding the filling tube 32 and the fixing member together. The first plate portion 22 has a fixing hole 221 that penetrates the first plate portion 22 along its thickness direction. The binding strap passes through the second through hole and the fixing hole 221, binding the first plate portion 22 and the connector together to fix the filling tube 32 to the first plate portion 22. In some embodiments of this application, the cable tie can also be wrapped around the filling tube 32 and the vent pipe 33, binding the filling tube 32, the vent pipe 33, and the fixing member together. In some embodiments of this application, the fixing hole 221 can be an elongated hole. This facilitates the installation of the binding strap.

[0083] Please refer to Figure 6 , Figure 7 and Figure 8 In some embodiments of this application, cable ties can be used to pass through the fixing hole 221 to bind the filling pipe 32, the exhaust pipe 33, and the first plate 22 together. This results in a simpler structure with fewer parts.

[0084] Please refer to Figure 1 and Figure 9 In some embodiments of this application, the upper side of the third plate portion 24 is used to abut against the intake pipe bracket 26, and the front side of the third plate portion 24 is provided with an avoidance notch 242 corresponding to the intake pipe 11.

[0085] Please refer to Figure 1 and Figure 9By having the upper side of the third plate 24 abut against the intake pipe bracket 26, the contact area between the third plate 24 and the intake pipe bracket 26 is larger, which helps to improve the stability of the installation of the third plate 24. By having a clearance notch 242 corresponding to the intake pipe 11 on the front side of the third plate 24, the third plate 24 is less likely to interfere with the intake pipe 11. The clearance notch 242 can avoid components such as the dust bag 111 of the intake pipe 11, and the third plate 24 can be set more compactly with the lower side of the intake pipe 11.

[0086] Please refer to Figure 1 and Figure 9 In some embodiments of this application, the intake pipe bracket 26 includes a fourth plate portion 261, the third plate portion 24 and the lower side of the intake pipe 11 are all disposed opposite to the fourth plate portion 261, the fourth plate portion 261 is fixedly connected to the third plate portion 24, and the fourth plate portion 261 abuts against the lower side of the intake pipe 11.

[0087] By including a fourth plate 261 in the intake pipe bracket 26, which is disposed opposite to the third plate 24 and fixedly connected to it, the intake pipe bracket 26 and the third plate 24 have a large connection area, which helps to improve the stability of the connection. By having the fourth plate 261 abut against the lower side of the intake pipe 11, the contact area between the fourth plate 261 and the lower side of the intake pipe 11 is large, which helps to improve the stability of the intake pipe bracket 26's support for the intake pipe 11.

[0088] Please refer to Figure 1 and Figure 9 In this embodiment of the application, the fixed connection between the fourth plate portion 261 and the third plate portion 24 can be implemented in various ways, such as by bonding, fastening, or welding.

[0089] Please refer to Figure 1 , Figure 8 and Figure 9 In some embodiments of this application, the third plate portion 24 has a strip-shaped hole 241 extending along the width direction x of the vehicle. A second fastener passes through the strip-shaped hole 241 and the fourth plate portion 261 to securely connect the third plate portion 24 and the fourth plate portion 261. Thus, the mounting position of the third plate portion 24 on the fourth plate portion 261 can be adjusted along the width direction x of the vehicle, which improves the adaptability of the mounting bracket 2 to various vehicle models.

[0090] Please refer to Figure 1 , Figure 8 and Figure 9In this embodiment of the application, the fourth plate portion 261 may be located between the third plate portion 24 and the lower side of the air intake pipe 11, that is, the fourth plate portion 261 directly abuts against the lower side of the air intake pipe 11. Alternatively, the third plate portion 24 may be located between the fourth plate portion 261 and the lower side of the air intake pipe 11, that is, the fourth plate portion 261 abuts against the lower side of the air intake pipe 11 through the third plate portion 24.

[0091] Please refer to Figure 1 , Figure 8 and Figure 9 In some embodiments of this application, the vehicle further includes at least one of the rear suspension bracket 12 and the front axle suspension bracket 13. One end of the fourth plate portion 261 is bent downward to form a fifth plate portion 262, and the lower end of the fifth plate portion 262 is bent horizontally to form a sixth plate portion 263. The lower side of the sixth plate portion 263 abuts against at least one of the rear suspension bracket 12 and the front axle suspension bracket 13, and the sixth plate portion 263 is fixedly connected to the vehicle frame through at least one of the rear suspension bracket 12 and the front axle suspension bracket 13.

[0092] By bending one end of the fourth plate 261 downwards to form the fifth plate 262, and bending the lower end of the fifth plate 262 horizontally to form the sixth plate 263, the manufacturing of the intake pipe bracket 26 is made more convenient, and the intake pipe bracket 26 can be formed by bending sheet metal. By having the lower side of the sixth plate 263 abut against at least one of the rear suspension bracket 12 and the front axle suspension bracket 13, the connection area between at least one of the rear suspension bracket 12 and the front axle suspension bracket 13 and the intake pipe bracket 26 is larger, which helps to improve the stability of the intake pipe bracket 26 on the vehicle frame.

[0093] Please refer to Figure 1 , Figure 8 and Figure 9 In some embodiments of this application, a fifth plate portion 262 is formed at the front end of a fourth plate portion 261. The fifth plate portion 262 extends along the width direction x of the vehicle. One end of the fifth plate portion 262 is connected to the fourth plate portion 261, and the other end is connected to a sixth plate portion 263.

[0094] Please refer to Figure 1 , Figure 8 and Figure 9Generally, in the vehicle width direction, the intake pipe 11 is a certain distance from the rear suspension bracket 12, and the intake pipe 11 is also a certain distance from the front axle suspension bracket 13. By extending the fifth plate portion 262 along the vehicle width direction x, the fifth plate portion 262 can connect the fourth plate portion 261 at the intake pipe 11, and the sixth plate portion 263 at the rear suspension bracket 12 and the front axle suspension bracket 13. By forming the fifth plate portion 262 at the front end of the fourth plate portion 261, the connection length between the fifth plate portion 262 and the fourth plate portion 261, and the connection length between the fifth plate portion 262 and the sixth plate portion 263, are both large in the vehicle width direction, which is beneficial to improving the reliability of the intake pipe bracket 26.

[0095] Please refer to Figure 1 , Figure 8 and Figure 9 Generally, along the width direction x of the vehicle, the rear cab suspension bracket and the front axle suspension bracket 13 are located near the center of the vehicle, while the air intake pipe 11 and the filling cup 31 are located near the edge of the vehicle. The fifth plate portion 262 extends along the width direction x of the vehicle and connects between the fourth plate portion 261 and the sixth plate portion 263, so that the weight of the air intake pipe 11 can act on one of the rear cab suspension bracket and the front axle suspension bracket 13.
