Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an integrated urea tank and vehicle. Background Technology

[0002] With increasingly stringent vehicle emission regulations, diesel vehicles commonly employ Selective Catalytic Reduction (SCR) technology to reduce nitrogen oxide (NOx) emissions. SCR systems require urea solution (usually AdBlue) as a reducing agent, necessitating the installation of a dedicated urea tank. However, modern vehicle chassis space is increasingly limited, especially in commercial vehicles and construction machinery, where the chassis must accommodate fuel tanks, batteries, exhaust systems, transmission components, and other devices, further restricting the installation space for urea tanks.

[0003] In traditional designs, the urea tank and fuel tank are typically located separately, each occupying chassis space and secured with individual straps. This split design not only increases the number of parts but also leads to complex installation, increased weight, and hinders overall vehicle weight reduction. Furthermore, when the urea tank is externally mounted, it is susceptible to external environmental factors (such as flying stones, mud, and rainwater), which may cause pipeline corrosion or urea solution contamination, affecting the normal operation of the SCR system.

[0004] To address these issues, the industry has recently begun exploring integrated designs for urea tanks and fuel tanks. This integrated solution can significantly save chassis space, reduce the number of installation and fasteners, and improve overall structural compactness. For example... Figure 1 As shown, in the prior art, a mounting groove is usually recessed at the bottom of the fuel tank, and the urea tank is inserted into the mounting groove. After the fuel tank is fixed to the frame 100, a bracket 200 is installed on the frame 100. The bracket 200 is located at the bottom of the fuel tank and is used to support the urea tank. Since the mounting positions of the frame 100 in the vertical direction Z are limited, when the bracket 200 needs to be set at the bottom of the fuel tank, it will inevitably lead to a reduction in the size of the fuel tank in the vertical direction Z, which in turn affects the volume of the fuel tank.

[0005] Therefore, there is an urgent need for integrated urea tanks to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an integrated urea tank and vehicle to solve the problem in related technologies where, due to the limited vertical mounting positions of the vehicle frame, when a support bracket for the urea tank needs to be installed at the bottom of the tank, the vertical dimensions of the tank will inevitably be reduced, thus affecting the tank's volume.

[0007] On the one hand, this utility model provides an integrated urea tank, which includes:

[0008] The fuel tank is configured to be fixed to the vehicle frame, and the fuel tank has a U-shaped receiving groove recessed along a first horizontal direction, and the receiving groove includes a bottom wall and a top wall spaced apart along a vertical direction.

[0009] A urea tank is disposed between the bottom wall and the top wall, and the bottom wall is used to support the urea tank.

[0010] A protective plate, wherein the protective plate is used to close the opening of the receiving slot, or the protective plate and the vehicle frame together close the opening of the receiving slot.

[0011] As a preferred technical solution for an integrated urea tank, the tank includes a side plate and a bottom plate fixedly connected to the side plate. The side plate is recessed into an L-shaped groove along the first horizontal direction. The groove wall of the L-shaped groove and the bottom plate form the receiving groove. The bottom plate is the bottom wall of the receiving groove.

[0012] As a preferred technical solution for an integrated urea tank, the tank is configured to be fixed to one side of the vehicle frame along a second horizontal direction, where the first horizontal direction is the vehicle length direction and the second horizontal direction is the vehicle width direction.

[0013] The frame is configured to block one side opening of the receiving slot along the second horizontal direction, and the protective plate is used to block the opening of the receiving slot along the first horizontal direction and the other side opening along the second horizontal direction.

[0014] As a preferred technical solution for integrated urea tanks, the portion of the vehicle frame opposite to the receiving slot is provided with a through hole;

[0015] The outlet pipe of the urea tank is used to pass through the through hole.

[0016] As a preferred technical solution for integrated urea tank tanks, an installation plate is provided on the inner wall of the accommodating slot at the opening on the other side of the second horizontal direction;

[0017] The protective plate includes a first plate and a second plate. The first plate is inserted into the opening on the other side of the receiving groove along the second horizontal direction and is fixedly connected to the mounting plate. The side plate where the opening on the other side of the receiving groove along the second horizontal direction is located is flush with the first plate. The second plate closes the opening of the receiving groove along the first horizontal direction.

[0018] As a preferred technical solution for integrated urea tanks, the first plate and the second plate are integrally formed parts.

[0019] As a preferred technical solution for an integrated urea tank, the protective plate is provided with a filling hole, which is used to be opposite to the filling port of the urea tank.

[0020] As a preferred technical solution for integrated urea tanks, a filling door is also included, which is pivotally connected to the protective plate and has two states: one with the filling hole closed and the other with the filling hole open.

[0021] As a preferred technical solution for integrated urea tanks, a sealing ring is also included. The sealing ring is disposed on the protective plate and located outside the filling hole. When the filling door closes the filling hole, the filling door and the protective plate clamp the sealing ring.

[0022] On the other hand, this utility model provides a vehicle including an integrated urea tank as described in any of the above embodiments.

[0023] The beneficial effects of this utility model are as follows:

[0024] This utility model provides an integrated urea tank and vehicle. The integrated urea tank includes a fuel tank, a urea tank, and a protective plate. The fuel tank is configured to be fixed to the vehicle frame. The fuel tank has a U-shaped receiving groove recessed along a first horizontal direction, and the receiving groove includes a bottom wall and a top wall spaced apart along a vertical direction. The urea tank is disposed between the bottom wall and the top wall, and the bottom wall supports the urea tank. The protective plate is used to close the opening of the receiving groove, or the protective plate and the vehicle frame jointly close the opening of the receiving groove. When the integrated urea tank is fixed to the vehicle frame, since the receiving groove for accommodating the urea tank is formed by the recess of the fuel tank along the first horizontal direction, when the urea tank is placed in the receiving groove, the bottom wall of the receiving groove directly supports the urea tank. This avoids the need to install a bracket on the vehicle frame. The bracket is located at the bottom of the fuel tank and is used to support the urea tank, thereby increasing the vertical dimension of the fuel tank and preventing the bracket from affecting the capacity of the fuel tank.

[0041] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] like Figures 2-6 As shown, this embodiment provides an integrated urea tank, which includes a tank 1, a urea tank 2, and a protective plate 3. The tank 1 is configured to be fixed to the frame 100. The tank 1 is recessed along the first horizontal direction X with a receiving groove 13. The receiving groove 13 is U-shaped and includes a bottom wall 132 and a top wall 133 spaced apart along the vertical direction Z. The urea tank 2 is disposed between the bottom wall 132 and the top wall 133. The bottom wall 132 is used to support the urea tank 2. The protective plate 3 is used to close the opening of the receiving groove 13, or the protective plate 3 and the frame 100 jointly close the opening of the receiving groove 13. The integrated urea tank is fixed to the vehicle frame 100. Since the receiving groove 13 for accommodating the urea tank 2 is recessed from the tank 1 along the first horizontal direction X, when the urea tank 2 is placed in the receiving groove 13, the bottom wall 132 of the receiving groove 13 directly supports the urea tank 2. This avoids the need to install a bracket 200 on the frame 100. The bracket 200 is located at the bottom of the tank 1 and is used to support the urea tank 2. This increases the size of the tank 1 along the vertical direction Z and prevents the bracket 200 from affecting the capacity of the tank 1.

[0043] Meanwhile, the protective plate 3 is used to close the opening of the receiving tank 13, or the protective plate 3 and the frame 100 together close the opening of the receiving tank 13. This setting can protect the urea tank 2. On the one hand, it can restrict the movement of the urea tank 2, thereby preventing the urea tank 2 from falling out of the receiving tank 13. On the other hand, it can prevent external mud and sand from contaminating the urea tank 2, or prevent external hard objects from damaging the urea tank 2.

[0044] Optionally, the fuel tank 1 includes a side plate 11 and a bottom plate 12 fixedly connected to the side plate 11. The side plate 11 is recessed in an L-shaped groove 131 along a first horizontal direction X. The wall of the L-shaped groove 131 and the bottom plate 12 form a receiving groove 13, and the bottom plate 12 is the bottom wall 132 of the receiving groove 13. In this embodiment, the receiving groove 13 is formed by the bottom plate 12 and the L-shaped groove 131 recessed along the first horizontal direction X. In other embodiments, the receiving groove 13 can also be directly recessed on the side plate 11 of the fuel tank 1, without needing to be formed by the bottom plate 12 or the top plate of the fuel tank 1.

[0045] Optionally, the fuel tank 1 is configured to be fixed to one side of the frame 100 along the second horizontal direction Y, where the first horizontal direction X is the length direction of the vehicle and the second horizontal direction Y is the width direction of the vehicle; the frame 100 is configured to block the opening of the receiving groove 13 on one side along the second horizontal direction Y, and the protective plate 3 is used to block the opening of the receiving groove 13 along the first horizontal direction X and the other opening along the second horizontal direction Y. In this embodiment, since the receiving groove 13 is recessed from the side wall of the fuel tank 1 along the first direction, the receiving groove 13 includes one opening along the first horizontal direction X and two openings along the second horizontal direction Y. When the fuel tank 1 is fixed to one side of the frame 100 along the second horizontal direction Y, the frame 100 can close one opening of the receiving groove 13 along the second horizontal direction Y. At this time, the other opening of the receiving groove 13 along the second horizontal direction Y and the one opening recessed along the first horizontal direction X are adjacent to each other. Therefore, the protective plate 3 can simultaneously close the other opening of the receiving groove 13 along the second horizontal direction Y and the one opening recessed along the first horizontal direction X, so that the protective plate 3 and the frame 100 can close the receiving groove 13.

[0046] Optionally, a through hole is provided at the part of the frame 100 opposite to the receiving groove 13; the liquid outlet pipe of the urea tank 2 is used to pass through the through hole. In this embodiment, this arrangement can, on the one hand, hide and cover the liquid outlet pipe of the urea tank 2, thereby preventing damage to the liquid outlet pipe of the urea tank 2 by external hard objects; on the other hand, this arrangement prevents the liquid outlet pipe of the urea tank 2 from passing through the protective plate 3, thereby improving the sealing performance of the protective plate 3 in blocking the receiving groove 13.

[0047] Optionally, an mounting plate 14 protrudes from the inner wall of the opening on the other side of the receiving groove 13 along the second horizontal direction Y; the protective plate 3 includes a first plate body 31 and a second plate body 32. The first plate body 31 is inserted into the opening on the other side of the receiving groove 13 along the second horizontal direction Y and is fixedly connected to the mounting plate 14. The side plate 11 where the opening on the other side of the receiving groove 13 along the second horizontal direction Y is located is flush with the first plate body 31. The second plate body 32 closes the opening of the receiving groove 13 along the first horizontal direction X. In this embodiment, since the opening on the other side of the receiving groove 13 along the second horizontal direction Y is located on the outside of the vehicle and is easily observed directly, an L-shaped mounting plate 14 is provided on the inner wall of the opening. When the first plate body 31 is inserted into the opening on the other side of the receiving groove 13 along the second horizontal direction Y, the first plate body 31 and the mounting plate 14 abut against each other, so that the side plate 11 where the opening on the other side of the receiving groove 13 along the second horizontal direction Y is located is flush with the first plate body 31.

[0048] Optionally, the first plate 31 and the mounting plate 14 are connected by bolts. In other embodiments, the first plate 31 and the mounting plate 14 may also be connected by snap-fit ​​or welding. The second plate 32 and the protective plate 3 are connected by bolts. In other embodiments, the second plate 32 and the protective plate 3 may also be connected by snap-fit ​​or welding.

[0049] Optionally, the first plate 31 and the second plate 32 are integrally formed parts. In this embodiment, the first plate 31 and the second plate 32 are sheet metal parts bent from a single plate. In other embodiments, the first plate 31 and the second plate 32 may also be formed by welding or gluing two plates together.

[0050] Optionally, the protective plate 3 is provided with a filling hole 33, which is used to be opposite to the filling port 21 of the urea tank 2. In this embodiment, the protective plate 3 is provided with a filling hole 33, and the filling hole 33 is opposite to the filling port 21 of the urea tank 2. This arrangement facilitates the filling of urea into the urea tank 2.

[0051] Optionally, the integrated urea tank also includes a filling door 4, which is pivotally connected to the protective plate 3 and has two states: a closed filling hole 33 and an open filling hole 33. In this embodiment, when urea is not needed in the urea tank 2, the filling door 4 closes the filling hole 33 to prevent external mud and sand from entering the receiving tank 13, and also to prevent hard objects from entering the filling hole 33, thus avoiding damage to the urea tank 2. When urea needs to be added to the urea tank 2, the filling door 4 opens the filling hole 33, allowing urea to be added.

[0052] Optionally, the filling port 21 of the urea tank 2 extends beyond the filling hole 33. The filling door 4 includes a hinge 41, an annular plate 42, and a clearance part 43. The hinge 41 pivotally connects the annular plate 42 to the protective plate 3. The clearance part 43 is fixed to the annular plate 42, and the clearance groove of the clearance part 43 is opposite to the opening of the annular plate 42. When the filling door 4 closes the filling hole 33, the filling port 21 passes through the opening and is located in the clearance groove. The purpose of the filling port 21 of the urea tank 2 extending beyond the filling hole 33 is to facilitate the filling of urea.

[0053] Optionally, the integrated urea tank also includes a sealing ring 5, which is disposed on the protective plate 3 and located outside the filling hole 33. When the filling door 4 closes the filling hole 33, the filling door 4 and the protective plate 3 clamp the sealing ring 5. In this embodiment, this arrangement can further improve the sealing performance of the filling door 4 when closing the filling hole 33.

[0054] This embodiment also provides a vehicle, including the integrated urea tank as described above.
