[0020] Reference Figure 1-3 The utility model proposes a device for verifying the split urea filling process, comprising: a urea tank 1, a support frame 2, a urea pipe 3, and a urea filling head sample 4;

[0021] The urea tank 1 is mounted on a support frame 2, which is equipped with a mounting bracket 5. The mounting bracket 5 is provided with a feed and discharge mounting position. The urea filling head sample 4 is made of transparent material and has a filling port 41, an outflow port 42, and a flow channel connecting the filling port 41 and the outflow port 42. The filling port 41 is removably mounted on the feed mounting position, while the outflow port 42 is removably mounted on the discharge mounting position. One end of the urea tube 3 is connected to the urea tank 1, and the other end is removably connected to the outflow port 42 of the urea filling head sample 4.

[0022] During use, the positions of the filling port 41 of the urea filling head sample 4 and the urea tank 1 are pre-set by simulating the positions of the urea tank 1 and the urea filling port 41 in an actual vehicle, and then urea liquid is added to the filling port 41 of the urea filling head sample 4 by simulating the flow of the urea filling gun. Since the urea filling head sample 4 is made of transparent material, the flow of the urea liquid can be intuitively observed at this time, thereby judging whether the structural design of the urea filling head sample 4 meets the requirements and where the unqualified problem specifically occurs.

[0023] As can be seen from the above, the utility model can simulate the position of the filling port 41 and the urea tank 1, and can visually see the flow direction of the urea liquid during the filling process, so as to facilitate the later structural optimization of the filling port 41 inside the urea filling head, greatly simplifying the physical verification cost, saving physical verification time, shortening the vehicle development cycle, and enhancing the product market versatility.

[0024] Furthermore, in this embodiment, a fixed mounting position is provided on the side of the mounting bracket 5 located at the discharge end mounting position away from the feed end mounting position, and the urea pipe 3 is fixedly installed at the fixed mounting position to avoid shaking of the urea pipe 3 during the feeding process, ensure the stability of the relative position of the urea pipe 3 and the outflow port 42, and reduce interference factors.

[0025] Furthermore, a connecting piece 6 is provided at the fixed installation position, and a mounting hole is provided on the connecting piece 6. The urea pipe 3 is fixed to the connecting piece 6 by inserting a cable tie into the mounting hole. This fixing method has a simple structure, low cost, and is quick and convenient to fix. In addition, the cable tie fixing method allows a certain adjustment space for the relative position between the urea pipe 3 and the outflow port 42.

[0026] In addition, this embodiment also provides an inlet adjustment seat 7 with an adjustable rotation angle at the inlet end mounting position, and an outlet adjustment seat 8 with an adjustable rotation angle at the outlet end mounting position.

During use, by adjusting the rotation angle of the inlet adjustment seat 7 and / or the outlet, the installation position of the filling port 41 and the outflow port 42 is adjusted to observe the flow of urea in the urea filling head sample 4, so as to find the optimal installation position of the structural design of this urea filling head sample 4.

[0027] The mounting bracket 5 in this embodiment includes a fixing base 51 and a cantilever 52. The fixing base 51 includes a first mounting surface and a second mounting surface, the first mounting surface and the second mounting surface being perpendicular to each other, and the first mounting surface being fixed to the support frame 2 by bolts.

The fixed mounting position is located at the angle between the first mounting surface and the second mounting surface, and the fixed mounting position, the feed end mounting position, and the discharge end mounting position are located on the same side of the cantilever 52. This structural design facilitates the installation, disassembly, and adjustment of components.

[0028] Furthermore, a first mounting hole is provided at the free end of the cantilever 52 to form a feed end mounting position, and a second mounting hole is provided at the end of the cantilever 52 close to the fixed seat 51 to form a discharge end mounting position. The feed end adjustment seat 7 is fixed to the mounting bracket 5 by a first threaded fastener passing through the first mounting hole, and the discharge end adjustment seat 8 is fixed to the mounting bracket 5 by a second threaded fastener passing through the second mounting hole.

[0029] Furthermore, the center portion of the inlet adjustment seat 7 is fixed to the mounting bracket 5 via a first threaded fastener.

Once the rotation angle is adjusted to the desired value, the first threaded fastener can be retightened. Similarly, the center portion of the outlet adjustment seat 8 is fixed to the mounting bracket 5 via a second threaded fastener. The rotation angle of the outlet adjustment seat 8 can be adjusted by loosening the second threaded fastener. Once the rotation angle is adjusted to the desired value, the second threaded fastener can be retightened.

[0030] Furthermore, the inlet adjustment seat 7 and the outlet adjustment seat 8 are both "J"-shaped structures, and the end where the filling port 41 of the urea filling head sample 4 is located and the end where the outflow port 42 is located are respectively installed on the "J"-shaped flange.

[0031] Furthermore, a third mounting hole is provided at the angle between the first mounting surface and the second mounting surface to form a fixed mounting position, and the connecting piece 6 is fixed at the angle between the first mounting surface and the second mounting surface by a threaded fastener inserted into the third mounting hole, so that the connecting piece 6 can be disassembled and replaced, and the connecting piece 6 is arranged at the angle to facilitate the control of the steering of the urea pipe 3.
