[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0024] Example:

[0025] like Figure 1As shown, an intelligent vehicle urea dispenser testing device includes a control system, an air compressor, a vehicle urea storage tank, a storage tank level sensor, a storage tank temperature sensor, a measuring cylinder mechanism, a return motor, a dispensing motor, and a vehicle urea dispenser under test. The outlet end of the vehicle urea storage tank is connected to the inlet end of the dispensing motor. The outlet end of the dispensing motor is detachably connected to the inlet end of the measuring cylinder mechanism via the vehicle urea dispenser under test. The dispensing motor provides power to the vehicle urea dispenser under test. The measuring cylinder mechanism has its outlet end connected to the inlet end of the return motor, and the return motor's outlet end is connected to the inlet end of the vehicle urea storage tank. The air compressor's outlet end is connected to the vehicle urea dispenser under test. The vehicle urea storage tank is equipped with a replenishment mechanism. The storage tank level sensor and storage tank temperature sensor are both located inside the vehicle urea storage tank. The storage tank level sensor, storage tank temperature sensor, air compressor, return motor, and dispensing motor are all connected to the control system.

[0026] Specifically, the replenishment mechanism includes a replenishment pump, a replenishment pipe, a replenishment solenoid valve, and an external replenishment container. One end of the replenishment pipe is connected to the external replenishment container, and the other end is connected to the inlet pipe of the vehicle urea storage tank. The replenishment pump and the replenishment solenoid valve are both installed on the replenishment pipe and are arranged sequentially along the flow direction of the vehicle urea solution in the pipe. The replenishment pump is equipped with a control module, and the control module and the replenishment solenoid valve are connected to the control system. This arrangement facilitates the replenishment of vehicle urea from the external replenishment container to the vehicle urea storage tank via the replenishment pump when the vehicle urea level in the storage tank is low.

[0027] like Figure 1 As shown, the measuring cylinder mechanism includes a 5L measuring cylinder, a 20L measuring cylinder, and a 50L measuring cylinder. The inlet end of the return motor is connected to the outlet end of the 5L measuring cylinder, the 20L measuring cylinder, and the 50L measuring cylinder, respectively. The outlet end of the return motor is connected to the inlet of the automotive urea storage tank. This arrangement facilitates the return of the automotive urea in the measuring cylinder to the automotive urea storage tank via the return motor at the end of the test, thereby ensuring the smooth progress of the test.

[0028] Specifically, the inlet ends of the 5L, 20L, and 50L measuring cylinders are filling interfaces. The 5L, 20L, and 50L measuring cylinders are detachably connected to the vehicle urea filling machine under test through the filling interfaces. This setting facilitates the vehicle urea filling machine to switch between measuring cylinders of different capacities for testing, thereby effectively reducing the error of the test results and improving the accuracy of the intelligent vehicle urea filling machine testing device.

[0029] Specifically, the 5L, 20L, and 50L graduated cylinders are all equipped with a drain valve and a drip tray. This arrangement facilitates the emptying of automotive urea that cannot be completely extracted by the return motor in the graduated cylinder, preventing residual automotive urea in the graduated cylinder from affecting the test results. In addition, the drip tray can also prevent automotive urea from polluting the environment, thereby improving the environmental friendliness of the intelligent automotive urea filling machine testing device.

[0030] The air compressor used is an Ottos 500W-8L air compressor.

[0031] Specifically, both the air compressor and the refueling motor are equipped with solenoid valves at their outlets. This arrangement allows operators to remotely operate the solenoid valves, facilitating the air compressor's purging of the pipeline and remote control of the refueling motor's start and stop.

[0032] The urea storage tank has a volume of 1200L and is equipped with a display and an alarm, both of which are connected to the control system. Specifically, in this embodiment, when the volume of the urea storage tank is less than 200L, the control system sends a signal to the alarm to issue a low-level alarm. At this time, the filling motor stops operating to prevent air from entering the pipeline due to the filling motor running dry, which would affect the testing accuracy of the device. In addition, prolonged idling of the filling motor can also cause damage to itself, thus affecting the durability of the device. When the volume of the urea storage tank is greater than 1000L, the control system sends a signal to the alarm to issue a high-level alarm. At this time, the return motor or the replenishment motor stops operating to prevent the urea storage tank from overflowing due to excessive urea, which would contaminate the ground.

[0033] The control system includes a controller, which is used to control the operating status of the return motor and the filling motor based on the liquid level sensor and the liquid temperature sensor of the storage tank.

[0034] The working principle of the intelligent vehicle urea filling machine testing device is as follows:

[0035] First, check that the urea reservoir is adequately filled. Connect the urea dispenser to the outlet line of the dispensing motor, and then connect the dispenser to the filling port of one of the graduated cylinders in the measuring cylinder mechanism. After confirming a secure connection between the dispenser and the filling port, start the dispensing motor. The urea from the reservoir will be pumped from the dispenser into the graduated cylinder. Once the cylinder is full, stop the dispensing motor and record the readings on the graduated cylinder. Then, read the data from the dispenser. Then start... The return motor delivers the automotive urea from the measuring cylinder to the automotive urea storage tank. During the delivery process, the outlet solenoid valve of the dispensing motor is closed, and the air compressor and its outlet solenoid valve are started to purge the residual automotive urea in the pipeline into the measuring cylinder. Then, the air compressor is stopped. Once the return motor has drawn all the automotive urea from the measuring cylinder into the automotive urea storage tank, the return motor is stopped. The above steps are then repeated to test the remaining measuring cylinders of the measuring cylinder mechanism. The test data is used to calculate the actual accuracy of the automotive urea dispensing machine under test, thus completing the test of the automotive urea dispensing machine under test.

[0036] Specifically, such as Figure 1 As shown, the vehicle urea dispenser under test has three positions, and the interfaces of all three positions are compatible with commonly used ton-type, MINI-type, and H-type vehicle urea dispensers on the market. During normal testing, only one position is usually selected as the test position for the vehicle urea dispenser under test. This setting allows for timely switching to the other two positions to continue testing if the current test pipeline or interface of the vehicle urea dispenser fails, thereby enhancing the stability of the intelligent vehicle urea dispenser testing device.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and agreed, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
