Specific Embodiments

[0022] The following will further describe in detail the specific embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0023] As Figure 1 - Figure 5 shown, an integrated layout structure of a vehicle urea tank according to an embodiment of the present invention includes a urea tank bracket 2 and a urea tank 1 arranged in the urea tank bracket 2. Among them, the urea tank bracket 2 is integrally arranged at the connection of the front bumper assembly 3 and the right upper vehicle step skeleton 5. The left side of the front bumper assembly 3 is connected to the left upper vehicle step skeleton 4, the right side of the front bumper assembly 3 is connected to the right upper vehicle step skeleton 5. The urea tank bracket 2 is located on the left side of the right upper vehicle step skeleton 5 and is placed between the right upper vehicle step skeleton 5 and the front large bracket 6 of the vehicle frame. The left side of the urea tank bracket 2 is connected to the front large bracket 6 of the vehicle frame, the right side of the urea tank bracket 2 is connected to the right upper vehicle step skeleton 5, and the front side of the urea tank bracket 2 is connected to the front lower protection cross beam 7; a filling port is provided on the urea tank 1, and the filling port is connected to a filling pipeline 11. The filling pipeline 11 extends upward from the filling port to the upper part of the front bumper assembly 3, and the upper end of the filling pipeline 11 is provided with a urea liquid filling port 12 for filling urea liquid into the urea tank 1.

[0024] After the present invention integrally sets the urea tank bracket 2 and the right upper vehicle step skeleton 5, and then combines with the front lower protection cross beam 7, it not only ensures the structural compactness and improves the problem of crowded layout space of the vehicle chassis, but also can realize the lightweight design of the urea tank bracket 2 and the right upper vehicle step skeleton 5 by virtue of the structural strength of the front lower protection cross beam 7 itself. Moreover, by setting the urea liquid filling port 12 at the upper part of the front bumper assembly 3, when filling urea liquid, it is necessary to unlock the front panel of the cab first to open the front panel for filling, which can prevent the theft of urea liquid.

[0025] As Figure 2 andFigure 4 As shown, in this embodiment, the urea tank bracket 2 is of a frame structure, and the lightweight of the urea tank bracket 2 is realized by using the frame structure.

[0026] Further, the urea tank bracket 2 includes a front bracket 21, a rear bracket 22, an upper support rod 23 and a lower support rod 24. Among them, the front bracket 21 and the rear bracket 22 are arranged at intervals front and rear. The two ends of the upper support rod 23 are respectively connected to the upper part of the front bracket 21 and the upper part of the rear bracket 22. The two ends of the lower support rod 24 are respectively connected to the lower part of the front bracket 21 and the lower part of the rear bracket 22. And the upper support rod 23 is arranged at the upper left of the lower support rod 24, and a placement space for placing the urea tank 1 is formed among the front bracket 21, the rear bracket 22, the upper support rod 23 and the lower support rod 24.

[0027] In this embodiment, the left side of the front bracket 21, the left side of the rear bracket 22, and the upper support rod 23 are respectively connected to the front large bracket 6 of the vehicle frame by bolts, which is convenient for installation and disassembly, and the fixing method is simple. And by integrally arranging the urea tank bracket 2 and the front large bracket 6 of the vehicle frame, the support bracket connecting the right upper vehicle pedal skeleton 5 and the longitudinal beam can be cancelled, reducing the weight and cost of the whole vehicle. Further, sleeves 25 are arranged between the left side of the front bracket 21, the left side of the rear bracket 22, the upper support rod 23 and the front large bracket 6 of the vehicle frame, and the bolts sequentially pass through the urea tank bracket 2, the sleeve 25 and the front large bracket 6 of the vehicle frame.

[0028] In this embodiment, the front lower protection cross beam 7 is connected with a support bracket 8. The support bracket 8 extends front and rear on the right side of the urea tank bracket 2, and the rear side of the support bracket 8 is connected to the right side of the rear bracket 22. The upper part of the front side of the support bracket 8 is connected to the front bumper assembly 3, and the lower part of the front side of the support bracket 8 is connected to the front lower protection cross beam 7. The support bracket 8 is arranged on the left side of the right upper vehicle pedal skeleton 5. The support bracket 8 plays a role in connecting the urea tank bracket 2 and the front lower protection cross beam 7. On the one hand, it can improve the collision resistance of the front lower protection cross beam 7. On the other hand, by virtue of the structural strength of the front lower protection cross beam 7 itself, the lightweight of the urea tank bracket 2 is realized.

[0029] Further, the support bracket 8 is arranged in parallel with the upper support rod 23, so that the space between the support bracket 8 and the upper support rod 23 is adapted to the width of the urea tank 1, facilitating the right side of the urea tank 1 to be abutted against the support bracket 8.

[0030] In this embodiment, the front bracket 21 and the front lower protection cross beam 7 are arranged at intervals, and the front side of the urea tank 1 can be abutted against the front lower protection cross beam 7. Further, as Figure 4 and Figure 5As shown in the figure, the front support bracket 21 includes an L-shaped connecting bracket 211, a first connecting belt 212, and a second connecting belt 213. The upper support rod 23 and the lower support rod 24 are both connected to the L-shaped connecting bracket 211. The first end of the first connecting belt 212 is fixed to one end of the L-shaped connecting bracket 211, and the first end of the second connecting belt 213 is fixed to the other end of the L-shaped connecting bracket 211. The second end of the first connecting belt 212 is detachably connected to the second end of the second connecting belt 213. The bottom of the urea tank 1 is placed on the horizontal part of the lower support rod 24 and the L-shaped connecting bracket 211. The left side of the urea tank 1 abuts against the upper support rod 23 and the vertical part of the L-shaped connecting bracket 211. The rear side of the urea tank 1 abuts against the rear support bracket 22, and the front side of the urea tank 1 abuts against the front lower protection cross beam 7. And the detachable connection of the first connecting belt 212 and the second connecting belt 213 facilitates placing the urea tank 1 into or taking it out of the urea tank support bracket 2, and can fix the urea tank 1 to the urea tank support bracket 2 to prevent the urea tank 1 from shaking in the urea tank support bracket 2. When the first connecting belt 212 and the second connecting belt 213 are disassembled, a placement space with an open top is formed in the urea tank support bracket 2. After the urea tank 1 is placed in this placement space, the first connecting belt 212 is fixed to the second connecting belt 213. The front support bracket 21 formed by the first connecting belt 212, the second connecting belt 213, and the L-shaped connecting bracket 211 is placed on the outer peripheral side of the urea tank 1, and the first connecting belt 212 and the second connecting belt 213 can play a fastening role on the urea tank 1.

[0031] In this embodiment, as Figure 5 shown, a first fixing column 2121 is provided at the second end of the first connecting belt 212, and a second fixing column 2131 is provided at the second end of the second connecting belt 213. Bolt holes are provided on both the first fixing column 2121 and the second fixing column 2131, and the first fixing column 2121 and the second fixing column 2131 are connected by a bolt 2132. Among them, the central axes of the first fixing column 2121 and the second fixing column 2131 are parallel, and the central axes of the first fixing column 2121 and the second fixing column 2131 both extend in the front-rear direction. The central axis of the bolt hole is perpendicular to the central axis of the first fixing column 2121.

[0032] It should be noted that the integrated layout structure of the vehicle urea tank 1 in the present invention is used for commercial vehicles and can also be used for other vehicles using the urea tank 1.

[0033] In summary, the embodiment of the present invention provides an integrated layout structure of a vehicle urea tank 1. The urea tank 1 is placed inside a urea tank bracket 2, and the urea tank bracket 2 is integrally arranged at the connection of the front bumper assembly 3 and the right upper vehicle pedal skeleton 5. The left side of the urea tank bracket 2 is connected to the front large bracket 6 of the vehicle frame, the right side of the urea tank bracket 2 is connected to the right upper vehicle pedal skeleton 5, and the front side of the urea tank bracket 2 is connected to the front lower protection cross beam 7. The structure is compact, improving the problem of crowded layout space of the vehicle chassis. Moreover, the urea liquid filling port 12 is arranged at the upper part of the front bumper assembly 3. When filling the urea liquid, the front panel of the cab needs to be unlocked first before it can be opened for filling, which can prevent the theft of urea liquid. Furthermore, after integrating the urea tank bracket 2 with the right upper vehicle pedal skeleton 5, the front side of the urea tank bracket 2 is connected to the front lower protection cross beam 7. Since the front lower protection cross beam 7 is specially designed for collision protection, its strength is redundant during normal use. After the integrated design of the urea tank bracket 2 and the right upper vehicle pedal skeleton 5 and the connection with the front lower protection cross beam 7, the structural strength of the front lower protection cross beam 7 is utilized, which is beneficial to the lightweight design of the urea tank bracket 2 and the right upper vehicle pedal skeleton 5. In addition, the connection of the urea tank bracket 2 to the outer side of the front lower protection cross beam 7 improves the collision strength of the front lower protection cross beam 7, meeting the requirements of collision regulations.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
