[0059] Referring to Figure 1 The present disclosure provides an output power test system, which includes a test chamber 1, a rotating hub test bench 2, a data collector 3 and a controller 4.

[0060] The rotating hub test bench 2 is located at the bottom of the test chamber 1, and is used to carry a vehicle to be tested. The data collector 3 is used to collect the voltage and current of the low-voltage load of the vehicle to be tested. The data collector 3 can be a current meter and a voltage meter. The controller 4 is used to calculate the low-voltage load output power of the vehicle to be tested based on the voltage and current of the low-voltage load.

[0061] The controller 4 can perform various calculations, receive and store collected data, etc.

[0062] The controller 4 can include a processor 210, a memory 220, a display component 230 and a communication component 240, as shown inFigure 2 As shown.

[0063] The processor 210 can be a central processing unit (CPU) or a system on chip (SoC), etc. The processor 210 can be used to process various operation instructions, for example, calculating the output power of the low-voltage load, etc.

[0064] The memory 220 can include various volatile memories or non-volatile memories, such as a solid state disk (SSD), a dynamic random access memory (DRAM) memory, etc. The memory 220 can be used to store initial data, intermediate data and result data used in the related processing process, for example, storing the pressure threshold, etc.

[0065] The display component 230 can be a separate screen, or a screen integrated with the user equipment body, a projector, etc. The screen can be a touch screen, or a non-touch screen (which can be displayed remotely), etc. The display component 230 is used to display system interfaces, application interfaces, etc., for example, displaying the test temperature, the test humidity, etc.

[0066] The communication component 240 can be a wired network connector, an ultra wide band (UWB) technology, a wireless fidelity (WiFi) module, a Bluetooth module, a cellular network communication module, etc. The communication component 240 can be used to receive and send various instructions and data, etc. For example, sending the output power of the low-voltage load to other equipment, etc.

[0067] In a possible implementation, for example Figure 3 As shown, the output power test system further includes a humidity simulation system 5, which includes a drying assembly 51, a humidifying assembly 52 and a humidity sensor 53.

[0068] The drying assembly 51 is in communication with the test chamber 1 and is electrically connected with the controller 4. The humidifying assembly 52 and the humidity sensor 53 are respectively arranged in the test chamber 1 and are electrically connected with the controller 4. For example Figure 4As shown, the drying assembly 51 comprises a drying chamber 511, a fan 512 and a drying medium 513. The drying chamber 511, the fan 512 and the test chamber 1 are sequentially communicated to form a circulation loop. The fan 512 is electrically connected with the controller 4. The drying medium 513 is arranged in the drying chamber 511 and can be uniformly distributed in the drying chamber 511. The fan 512 comprises a housing 5121, a motor 5122 and a plurality of blades 5123. The housing 5121 is electrically connected with the motor 5122. The plurality of blades 5123 are connected with each other at one point and fixed in the housing 5121. The motor 5122 is electrically connected with the controller 4, and the controller 4 can control the motor 5122 to work.

[0069] The controller 4 is configured to receive a humidity setting instruction, obtain a target humidity corresponding to the humidity setting instruction, and obtain a current humidity detected by the humidity sensor 53. When the current humidity is higher than the target humidity, the controller 4 controls the drying assembly 51 to work based on a difference between the current humidity and the target humidity. When the target humidity is higher than the current humidity, the controller 4 controls the humidifying assembly 52 to work based on a difference between the target humidity and the current humidity. The controller 4 is configured to control the fan 512 to work based on the difference between the current humidity and the target humidity when the current humidity is higher than the target humidity, and control the humidifying assembly 52 to work based on the difference between the target humidity and the current humidity when the target humidity is higher than the current humidity. For example, when the controller 4 receives a humidity setting instruction with a target humidity of 60%, if the current humidity is 70%, the current humidity is higher than the target humidity. At this time, the controller 4 controls the drying assembly 51 to work, and the controller 4 can also determine the working gear of the drying assembly 51 according to the difference between the current humidity and the target humidity.

[0070] When the drying assembly 51 works, the A and B channels shown in Figure 4 are opened, the A and B channels are respectively communicated with the test chamber 1, and the fan 512 is controlled to start working. The air in the test chamber 1 is blown to the drying chamber 511 by the fan 512. The drying medium 513 in the drying chamber 511 absorbs the moisture in the air. Then, the air flows out of the drying chamber 511 through the channels and flows to the test chamber 1. In this way, the humidity of the air in the test chamber 1 is reduced.

[0071] In a possible implementation, for example Figure 5 as shown, the output power test system further comprises a sunlight simulation system 6. The sunlight simulation system 6 comprises a first moving assembly 61 and a high-energy radiation lamp 62.

[0072] The first moving assembly 61 is located in the test chamber 1, connected with the test chamber 1, and electrically connected with the controller 4. The first moving assembly 61 comprises a first annular moving track 611, an arc-shaped moving track 612, and a displacement member 613. The first annular moving track 611 is located above the hub test bench 2 in the test chamber 1, surrounds the hub test bench 2, and is connected with the test chamber 1. The arc-shaped moving track 612 is perpendicular to the first annular moving track 611, the arc center of the arc-shaped moving track 612 is located at the position of the vehicle to be tested, the arc-shaped moving track 612 is connected with the first annular moving track 611 and can move along the first annular moving track 611 under the control of the controller 4. The displacement member 613 is connected with the arc-shaped moving track 612 and can move along the arc-shaped moving track 612 under the control of the controller 4. The displacement member 613 is connected with the high-energy radiation lamp 62.

[0073] The high-energy radiation lamp 62 is located in the test chamber 1, connected with the first moving assembly 61, and electrically connected with the controller 4. The high-energy radiation lamp 62 faces the position of the vehicle to be tested. The high-energy radiation lamp 62 can adjust the height relationship between the high-energy radiation lamp 62 and the position of the vehicle to be tested by moving along the arc-shaped moving track 612. The high-energy radiation lamp 62 is installed at a specified height above the hub test bench 2. The specified height can be set by the tester in advance.

[0074] The controller 4 is configured to receive a light setting instruction, obtain a target light angle corresponding to the light setting instruction, control the first moving assembly 61 to move the high-energy radiation lamp 62 based on the target light angle, and control the high-energy radiation lamp 62 to emit light. The controller 4 is configured to obtain a light intensity corresponding to the light setting instruction, and control the high-energy radiation lamp 62 to emit light based on the light intensity.

[0075] In a possible implementation, for example Figure 6 As shown, the output power test system further comprises a wind simulation system 7, which comprises a second moving assembly 71 and a fan module 72. The wind simulation system 7 can comprise one or more multi-joint mechanical arms 712 and one or more fan modules 72. The number of multi-joint mechanical arms 712 is the same as that of the fan modules 72.

[0076] The second moving assembly 71 is located in the test chamber 1, connected with the test chamber 1, and electrically connected with the controller 4. The second moving assembly 71 comprises a second annular moving track 711 and a multi-joint mechanical arm 712. The second annular moving track 711 is located at the bottom of the test chamber 1, surrounds the hub test bench 2, and is connected with the test chamber 1. The first end 712a of the multi-joint mechanical arm 712 is connected with the second annular moving track 711, and the second end 712b of the multi-joint mechanical arm 712 is connected with the fan module 72. The multi-joint mechanical arm 712 can move along the second annular moving track 711 under the control of the controller 4, and can adjust the orientation of the fan module 72 under the control of the controller 4. The multi-joint mechanical arm 712 can comprise a plurality of joints and a plurality of connecting components. Each connecting component connects two joints, one end of each connecting component is connected with one joint, and the other end is connected with another joint, so as to realize the connection of the two joints.

[0077] The fan module 72 is located in the test chamber 1, connected with the second moving assembly 71, and electrically connected with the controller 4. The fan module 72 is located towards the position of the vehicle to be tested. The fan module 72 comprises a fan support 721 and a plurality of fan units 722. The fan support 721 is connected with the second moving assembly 71. The fan units 722 are located on the fan support 721 and connected with the fan support 721. The fan units 722 can adjust their own posture relative to the fan support 721 under the control of the controller 4.

[0078] The controller 4 is used for receiving an air flow setting instruction, obtaining a target air flow direction corresponding to the air flow setting instruction, controlling the second moving assembly 71 to move the fan module 72 based on the target air flow direction, keeping the fan module 72 oriented towards the position of the vehicle to be tested, and controlling the fan module 72 to blow air.

[0079] In a possible implementation, for example Figure 7 As shown, the hub test bench 2 comprises a support plate 21, a support frame 22 and a plurality of hubs 23. The support plate 21 is located at the bottom of the test chamber 1. The support plate 21 has a plurality of through holes 21a. The number of through holes in one support plate 21 can be determined by a technician, which can be two, four, Figure 6 The support frame 22 is located below the support plate 21 and connected with the support plate 21. Figure 6 The black long strip in the figure represents the hub 22. The plurality of hubs 22 are parallel to each other and parallel to the support plate 21. Each two hubs 22 correspond to one through hole 21a. The upper edge of the hub 22 is located at the corresponding through hole 21a. Each hub 22 is rotatably connected with the support frame 22. The two hubs 22 corresponding to the same through hole 21a are used to support at least one tire of the vehicle to be tested. One of the two hubs 22 is used to support the bottom front side of the at least one tire, and the other hub 22 is used to support the bottom rear side of the at least one tire.

[0080] In a possible implementation, the hub test bench 2 further comprises a plurality of pressure sensors 24. The plurality of pressure sensors 24 are evenly distributed on the cylindrical surface of each hub 22 in the circumferential direction, and are respectively electrically connected to the controller 4. The surface of the hub 22 can also be sleeved with a protective sleeve. The controller 4 is configured to, for each hub 22, continuously determine a total pressure value obtained by summing pressure values detected by all pressure sensors 24 corresponding to the hub 22, and obtain time-varying data of the total pressure value. When the tire of the vehicle under test is in contact with the hub 22 and drives the hub 22 to rotate, the detection mode can be manual input of a start test instruction, or the controller 4 can detect that the continuous M peak values are greater than a pressure threshold value (a first pressure threshold value, which is set by a tester in advance). If the continuous N peak values of the total pressure value are all less than a pressure threshold value (a second pressure threshold value, which is set by a tester in advance, and the second pressure threshold value is less than the first pressure threshold value), N is a preset positive integer, an alarm signal is sent, wherein the alarm signal is used to indicate that the vehicle speed of the test vehicle is too fast. For example, when the peak values of the continuous 3 pressure sensors 24 are all less than 500, the controller 4 controls the loudspeaker to send an alarm prompt sound. The alarm prompt sound can be various, which is set by the user arbitrarily.

[0081] In a possible implementation, the processing flow of the controller 4 for calculating the output power of the low-voltage load can be as shown in Figure 8 , and includes the following steps.

[0082] 801. Calculate the output power of each low-voltage load based on the voltage and current of the low-voltage load.

[0083] The controller 4 receives the voltage and current of each low-voltage load collected by the data collector 3, and calculates the output power of the low-voltage load based on the voltage and current of each low-voltage load.

[0084] 802. Calculate the sum of the output power of each low-voltage load as the output power of the low-voltage load of the vehicle under test.

[0085] After the controller 4 calculates the output power of each low-voltage load, the sum of the output power of all low-voltage loads is calculated as the output power of the low-voltage load of the vehicle under test.

[0086] In a possible implementation, the output power test system further comprises a bus signal collector, and the processing flow for determining whether the low-voltage load meets the processing requirement can be as shown in Figure 9 , and includes the following steps.

[0087] 901. The bus signal collector collects the bus signal.

[0088] 902, the controller 4 determines whether the low-voltage load of the vehicle under test meets the processing requirement based on the bus signal, the low-voltage load output power of the vehicle under test, and the target low-voltage load output power of the vehicle under test.

[0089] Based on the bus signal, the low-voltage load output power, and the target low-voltage load output power, if the low-voltage load output power is greater than the target low-voltage load output power, it is necessary to check whether the design of the low-voltage load meets the processing requirement, and if the difference between the low-voltage load output power and the target low-voltage load output power is less than the difference threshold, it is indicated that the design of the low-voltage load meets the processing requirement.

[0090] In the embodiments of the present disclosure, the output power test system is used to test the low-voltage load output power of the vehicle under test, without the need for a large test site, and the output power test system only needs to occupy the site size of a test bin, the land area of the test bin is not much larger than a car, and moreover, the hub test bench, the data collector, and the controller are not very complex devices. It can be seen that the construction of the power test system is much simpler than the construction of a large test site. The use of the power test system for testing the low-voltage load output power of the vehicle makes the testing process simpler and easier to implement.
