[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] The electric air outlet 400 is an intelligent adjustable air outlet for the vehicle air conditioner, which is designed to control the working parameters in the electric air outlet 400 such as the opening and closing, swing angle and swing speed of the swing blades through the central control screen, thereby realizing the opening and closing of the electric air outlet 400 and the adjustment of the air outlet direction.

[0024] like Figure 1-4 As shown, a vehicle electric air outlet 400 test device is used for testing the electric air outlet 400. The test device includes a control module 210 and a test device 300. The control module 210 is used to obtain test information and generate an air volume adjustment signal, an air outlet control signal and a simulated environment signal according to the test information. Specifically, the test information includes air volume parameters, air outlet control parameters and input environment parameters. The air volume adjustment signal can be generated according to the air volume parameters, the air outlet control signal can be generated according to the air outlet control parameters, and the simulated environment signal can be generated according to the input environment parameters.

[0025] The air outlet control signal and the simulated environment signal generated by the control module 210 are respectively sent to the electric air outlet 400. The electric air outlet 400 receives and responds to the air outlet control signal to adjust the working parameters. For example, if the electric air outlet 400 uses a motor to control the swinging blades to adjust the opening and closing, the air outlet size, the air outlet direction, and the swinging speed, the electric air outlet 400 controls the motor after receiving the air outlet control signal, thereby controlling the swinging blades and adjusting the air outlet size and the air outlet direction.

[0026] In addition, the electric air outlet 400 also receives a simulated environment signal, which is used to simulate the vehicle network communication environment so that the electric air outlet 400 can operate normally. At the same time, it can also better simulate the use of the electric air outlet 400 in the vehicle. Among them, the simulated environment signal includes a power status signal and a vehicle speed signal. Generally, the power status signal is that the power of the whole vehicle is in the off state, and the electric air outlet 400 should be in a closed and uncontrollable state, and the size of the vehicle speed will also have a certain impact on the swing angle of the electric air outlet 400. By simulating the vehicle network communication environment, the communication status of the electric air outlet 400 and the related control logic can be tested, making the test range wider and more comprehensive. In other embodiments, the simulated environment signal may also include a temperature signal, an external wind speed signal, and the like.

[0027] The control module 210 is connected to the test device 300 via a hard line, and the control module 210 generates an air volume adjustment signal and sends it to the test device 300. The test device 300 includes a fan 310, an air duct 320, and a collector 330. The fan 310 receives the air volume adjustment signal and adjusts the output air volume of the fan 310 according to the air volume adjustment signal, wherein the fan 310 can be a blower 310 or a fan. The air duct 320 is used to connect the output end of the fan 310 with the air inlet end of the electric air outlet 400, and guide the wind generated by the fan 310 to flow to the air inlet end of the electric air outlet 400 to simulate the wind formed by the vehicle air conditioning system. The collector 330 is arranged at the outlet of the electric air outlet 400, and is used to collect the output air volume information of the electric air outlet 400, wherein the collector 330 is composed of nine air volume meters, and the nine air volume meters are arranged in a matrix of three rows and three columns, thereby forming nine air volume measurement points, which can be used to measure the air volume data of the nine positions and display them to form the air volume information of the outlet. In other embodiments, according to the air outlet structure of the electric air outlet 400 and actual needs, the collector 330 can also be composed of three, five, six, twelve or other numbers of air volume meters.

[0028] The present invention can test the performance of the electric air outlet 400 through the control module 210 and the testing device 300. By analyzing the air volume information at the air outlet obtained according to different test information, the function and performance of the electric air outlet 400 can be verified. At the same time, test data can be provided for the optimized design of the electric air outlet 400.

[0029] Optionally, the test equipment further includes a data processing module, which can be integrated with the control module 210 to form a real-time processor control platform 200. The data processing module is used to obtain test information and receive air volume information at the air outlet. The data processing module determines the performance of the electric air outlet 400 based on the air volume information and the test information at the air outlet and displays it. The test information also includes test indicators, wherein the test indicators include standard air volume information at the air outlet of the electric air outlet 400 under preset air volume parameters, air outlet control parameters, and input environmental parameters. The data processing module sorts out the air volume information at the air outlet and the standard air volume information at the air outlet, and then compares and analyzes them. According to the test indicators, it is determined whether the electric air outlet 400 meets the test indicators and meets the design requirements, and the comparison process and judgment results are displayed, thereby improving the test efficiency and facilitating the subsequent further improvement of the electric air outlet 400.

[0030] Optionally, the test device further includes an operation interface 110, which is used for a user to input test information and send the test information to the control module 210. Specifically, the operation interface 110 is a host computer control interface, and the operation interface 110 is connected to the control module 210 via Ethernet. The operation interface 110 can set initial parameter values, i.e., test information, for the control module 210 to implement manual testing.

[0031] Optionally, the test equipment further includes an automated test module 120, and the operation interface 110 and the automated test module 120 are integrated to form the test management system 100. The operation interface 110 is also used for the user to input automated test sequence information, and the automated test module 120 generates and regularly sends air volume adjustment signals, air outlet control signals, and simulated environment signals according to the automated test sequence information. The automated test module 120 can write an automated test sequence according to the automated test sequence information input in the operation interface 110, i.e., the content of the automated test steps, etc., and convert the designed test method into an automated test program, thereby completing the automated test and improving the test consistency and test efficiency.

[0032] Optionally, the control module 210 includes an air volume regulating unit 211, an air volume collection unit 212, an environment simulation unit 213, and an air outlet control unit 214. The air volume regulating unit 211 receives air volume parameters, and converts the air volume parameters into air volume regulating signals, and sends the air volume regulating signals to the fan 310 to control the air volume of the fan 310 and simulate the air outlet intensities of different intensities. The air outlet control unit 214 receives the air outlet control parameters, and converts the air outlet control parameters into air outlet control signals, and sends the air outlet control signals to the electric air outlet 400 to simulate the electric air outlet 400 command to control the working parameters of the electric air outlet 400. The processor inside the air volume collection unit 212 reads the air volume data of the air volume meter in the collector 330 in real time through the cable, and stores, analyzes, and sends the air volume data to the data processing module, etc. The environment simulation unit 213 is used to simulate the vehicle network communication environment, such as power state, vehicle speed and other environmental signals, so that the electric air outlet 400 can operate normally, thereby realizing the division of different functional units.

[0033] The performance of the electric air outlet 400 includes an air volume loss parameter, which is determined according to the air volume adjustment signal and the air volume information of the air outlet. Exemplarily, the air outlet control parameter is input to make the electric air outlet 400 in an open state, and the wind flows out from the air outlet of the electric air outlet 400. The air volume at the air outlet of the electric air outlet 400 is collected by the collector 330 to obtain the air volume information of the air outlet. The data processing module compares the air volume value a1 of the air outlet determined in the air volume information of the air outlet with the air volume value a2 blown out by the fan 310 determined by the air volume adjustment signal, and obtains the air volume loss parameter A (A=a2 / a1 or A=a2-a1 or A=1-a2 / a1). The air volume loss parameter represents the loss of wind before and after passing through the electric air outlet 400. It should be noted that when the fan 310 adjusts the air volume according to the air volume adjustment signal, there is only one determined air volume value a2. In other embodiments, the testing device 300 also includes a fan 310 air volume measuring device, which tests the air volume of the fan 310 or the air volume at the air inlet of the electric air outlet 400 to obtain the air volume information at the air inlet, and the air volume loss parameter is determined by the air volume information at the air inlet and the air volume information at the air outlet.

[0034] Optionally, the data processing module is also used to obtain no-load air volume information, which is the air volume information at the air outlet measured by the collector 330 when the test device 300 is no-load. The air volume loss parameter is determined by the air volume adjustment signal, the air volume information at the air outlet and the no-load air volume information.

[0035] Exemplarily, before the air volume loss parameter is determined, the electric air outlet 400 may not be installed or may be removed, the same test conditions may be set, and the air volume information of the air outlet at this time may be collected through the collector 330, and the no-load air volume value a3 of the air outlet may be determined based on the air volume information of the air outlet. After the electric air outlet 400 is installed, the air volume value a1 of the air outlet is measured under the same test conditions, and the optimized air volume loss parameter A [A=(a2+A3) / a1] is determined based on the air volume value a1 of the air outlet, the air volume value a2 blown out by the fan 310, and the no-load air volume value a3 of the air outlet. It can be understood that the no-load air volume information is the performance parameter of the air duct 320. In the test device 300, after determining the relationship and parameters between the fan 310, the air duct 320, and the collector 330, the corresponding no-load air volume information may be obtained. It should be noted that when there are multiple air volume test points, the air volume value with the largest value among the multiple air volume values ​​obtained is selected as the air volume value at the air outlet. In other embodiments, the average value of multiple air volume values ​​can also be used as the air volume value at the air outlet.

[0036] The performance of the electric air outlet 400 also includes swing performance. The collector 330 is also used to collect swing air volume information. The swing air volume information is the air volume information of the air outlet at different positions of the electric air outlet under different working parameters. The data processing module determines the swing performance based on the swing air volume information.

[0037] Exemplarily, the air outlet control parameters are input so that the swing blades of the electric air outlet 400 have preset lateral swing angles and longitudinal swing angles. The electric air outlet 400 is tested by the test device 300 to obtain the air volume information of the air outlet. The air volume information of the air outlet includes the air volume data corresponding to the nine air volume test points, which can constitute the air volume distribution diagram of the air outlet. The data processing module can obtain the air outlet angle and air volume of the electric air outlet 400 according to the air volume distribution diagram. By setting multiple groups of air outlet control parameters for multiple tests, the air outlet angle and air volume of the electric air outlet 400 under the test conditions of different air outlet control parameters can be quantitatively analyzed. By analyzing different air outlet control parameters and the corresponding air outlet angles and air volumes, the air outlet angle and air volume are compared and analyzed with the standard value or design value under the air outlet control parameters to determine the swing performance of the electric air outlet 400. Therefore, the swing performance is used to evaluate the air outlet direction and air volume of the electric air outlet 400 under the preset swing angle. In other embodiments, a dynamic air volume test point may also be set to test the air volume information of the air outlet at different positions by moving.

[0038] In other embodiments, the swing performance can also be used to evaluate the change in the direction of the wind outlet of the electric air outlet 400 at a preset swing speed, the change in the wind volume, and the cumulative value. The swing performance is only for the electric air outlet 400 with the swing function. Exemplarily, the air outlet control parameters are input so that the swing blades of the electric air outlet 400 have a preset lateral swing speed and longitudinal swing speed. The electric air outlet 400 is tested by the test device 300 to obtain the distribution diagram of the wind volume information at the air outlet end over time. After processing and analysis, the data processing module can obtain the change in the direction of the wind outlet of the electric air outlet 400, the change in the wind volume, and the cumulative value of the wind volume at each test point during the period of time. The change in the direction of the wind outlet and the change in the wind volume of the electric air outlet 400 are compared and analyzed with the standard value or design value under the air outlet control parameters, and the difference between the cumulative values ​​of the wind volume at different wind volume test points is used to determine the swing performance of the electric air outlet 400.

[0039] Optionally, the performance of the electric air outlet 400 also includes airtightness performance, and the collector 330 is also used to collect air volume information at the air outlet of the electric air outlet 400 in a closed state as sealing air volume information, and the data processing module determines the airtightness performance based on the sealing air volume information.

[0040] Specifically, the air outlet control parameters are input to close the electric air outlet 400, and the air volume information at the air outlet end at this time, such as the air volume size, is measured as the sealing air volume information. The data processing module determines the sealing performance of the electric air outlet 400 in the closed state according to whether the air volume is detected, so as to determine the airtightness of the electric air outlet 400. A gravity air discharge port 500 is arranged at the upper part of the air duct 320. When the electric air outlet 400 is closed, the air pressure in the air duct 320 increases, and the air blown by the fan 310 is discharged from the gravity air discharge port 500, which plays a role of overpressure protection; when the electric air outlet 400 is opened, the gravity air discharge port 500 is closed with gravity to ensure the airtightness of the air duct 320. The gravity air discharge port 500 does not require energy to drive, and has a simple and practical structure. In other embodiments, an electric exhaust door may be used instead of the gravity air discharge port 500. The exhaust door may be opened while the electric air outlet 400 is closed, and the exhaust door may be closed while the electric air outlet 400 is opened, so as to provide overpressure protection while also ensuring the air tightness of the air duct 320.

[0041] Optionally, the testing device 300 may also include a moving device, which can push the collector 330 to move, and multiple air volume test points move synchronously and slowly, thereby expanding the collection range and ensuring that no possible air leakage points in the air outlet end of the electric air outlet 400 are left behind, so as to ensure the accuracy of the airtight performance of the electric air outlet 400.

[0042] Optionally, the performance of the electric air outlet 400 includes durability performance, and the collector 330 is also used to collect the air volume information at the air outlet of the electric air outlet 400 before and after maintaining the working state for a first preset time as the initial air volume information and the current air volume information, and determine the durability performance based on the initial air volume information and the current air volume information, wherein the swing blades of the electric air outlet 400 swing at least a second preset time and / or a third preset number of times within the first preset operating time.

[0043] Specifically, input the air outlet control parameters, measure the air volume information of the air outlet end of the electric air outlet 400 under the preset test information at the start time of the first preset time as the initial air volume information, and keep the electric air outlet 400 in the working state for the first preset time, such as 100 hours or 1000 hours. During the first preset time, control the electric air outlet 400 to open and close, swing up and down, and swing left and right, so as to better simulate the actual use of the electric air outlet 400 on the vehicle, and then measure the air volume information of the air outlet end of the electric air outlet 400 under the preset test information at the end time of the first preset time as the current air volume information. By comparing and analyzing the changes in the initial air volume information and the current air volume information, the durability of the electric air outlet 400 can be determined. It should be noted that within the first preset time, the number and time of controlling the opening and closing, up and down swinging, and left and right swinging of the electric air outlet 400 are respectively not less than the third preset number and the second preset time. It can be understood that the third preset number refers to the number of times the electric air outlet 400 completes the swinging action command, and the second preset time refers to the accumulated time of the electric air outlet 400 under the swinging action.

[0044] The air volume information and current air volume information under the corresponding test conditions can be used to judge the airtightness performance, swing performance and air volume loss parameters of the electric air outlet 400 before and after a preset time, so as to determine the performance stability of the electric air outlet 400 when it is in a long-term working state, and to judge the durability of the electric air outlet 400.

[0045] Exemplarily, during the test, the user manually inputs test information, namely, air volume parameters, air outlet control parameters, input environmental parameters and test indicators in the operation interface 110, wherein the air volume parameters include the air volume at the outlet of the fan 310; the air outlet control parameters include the lateral swing angle and the longitudinal swing angle of the electric air outlet 400, the lateral swing speed and the longitudinal swing speed of the electric air outlet 400, wherein when the lateral swing angle and the longitudinal swing angle of the electric air outlet 400 are both 0, it indicates that the electric air outlet 400 is in a closed state; input environmental parameters include power status and vehicle speed; test indicators include air volume loss parameter standard, swing angle and air outlet angle relationship standard, swing angle and air outlet volume relationship standard, and change standard between initial air volume information and current air volume information.

[0046] The operation interface 110 sends the air volume parameters, air outlet control parameters, input environment parameters and test indicators to the control module 210. The control module 210 can convert the above parameter commands into circuit control commands, thereby realizing the test process control and data analysis of the test device 300 and the electric air outlet 400, obtaining the corresponding electric air outlet 400 performance and evaluation, and completing this manual test. It should be noted that in a manual test process, a variety of electric air outlet 400 performances can be obtained. For example, the air outlet control parameters give a horizontal swing angle and a vertical swing angle that are not 0. At this time, the air volume information of the air outlet can not only be used for the analysis and evaluation of the swing performance, but also for the analysis and evaluation of the air volume loss parameters. In addition, the operation interface 110 can also provide the user with performance evaluation options for the electric air outlet 400, such as air volume loss test, swing angle performance test, swing speed performance test, sealing performance test, and durability performance test. After the user's selection, the operation interface 110 can provide the user with corresponding interface information according to the selected test type, so that the user can input the test information required in the selected test type.

[0047] If automated testing is required, the test process information can be input through the operation interface 110, and the designed test method can be converted into an automated test program according to the test process information and the automated test sequence to complete the automated test, thereby improving the test consistency and test efficiency. Manual operations can be automated through automated scripts to save manpower.

[0048] In other embodiments, the test device 300 may further include a temperature control device installed in the air duct 320, the temperature control device includes a refrigerator, a heater and a temperature sensor, and the test information also includes air volume temperature parameters. After the control module 210 obtains the air volume temperature parameters, it generates and sends a temperature adjustment signal to the refrigerator and the heater to make the refrigerator or the heater work. At the same time, the refrigerator and the heater also receive the temperature signal of the temperature sensor and adjust the working state so that the temperature signal of the temperature sensor meets the test conditions, that is, the wind temperature in the air duct 320 meets the air volume temperature parameters. By controlling the operation of the heater and the refrigerator, the wind in the air duct 320 can be temperature-controlled, further simulating the actual wind conditions of the vehicle air conditioner.
