Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle testing technology, and in particular to a door testing device. Background Technology
[0002] To ensure the integrity of electric door performance, testing is necessary. Only after the electric doors pass the test can vehicles equipped with them be released to the market. In existing technology, door testing equipment utilizes the door opening and closing mechanism installed on the door to open or close it. However, this mechanism only verifies the mechanical performance of the door from the outside; it cannot determine whether the vehicle controller synchronously generates the vehicle message signal for door opening and closing, nor can it assess the accuracy of the vehicle signal logic, resulting in low test accuracy. Utility Model Content
[0003] This utility model provides a vehicle door testing device to solve the technical problems of low test result accuracy in existing vehicle door testing devices.
[0004] An embodiment of this utility model provides a vehicle door testing device for testing the doors of a vehicle under test, including an actuator and a control component;
[0005] The actuator is installed on the door of the vehicle under test and is positioned opposite the door switch of the vehicle, and is used to press the door switch;
[0006] The control component is electrically connected to both the actuator and the vehicle controller of the vehicle under test, and is used to send and receive vehicle message information based on the vehicle controller, and control the actuator to press the door switch.
[0007] In this application, the control component can control the actuator to press the door switch. After the door switch is pressed by the actuator, the door will perform operations such as opening and closing. Simultaneously, the control component can also send, receive, and parse vehicle message signals through the vehicle controller. The control component combines the vehicle message signals with the door actions to perform a complete closed-loop test process, determining whether the actuator's action of pressing the door switch corresponds to the vehicle message signal, thereby determining whether the door switch can correctly perform the relevant actions after being pressed by the actuator, and enabling door durability testing. Compared to existing control components that only externally press the door switch via an actuator and do not interact with the vehicle controller, the door testing equipment of this application can directly connect to the vehicle controller, sending, receiving, and parsing vehicle message signals, realizing an automated, fully closed-loop testing scheme for the door, thus improving the testing accuracy and precision of the door testing equipment. Furthermore, this door testing equipment has a simple structure, low manufacturing cost, and convenient testing operation.
[0008] Optionally, the control component includes a data acquisition card, a motion control card, and an industrial computer; the industrial computer is electrically connected to the vehicle controller; the data acquisition card, the motion control card, and the actuator are all electrically connected to the industrial computer.
[0009] In this embodiment, the motion control card can control the actuator to press the door switch, and the data acquisition card can acquire the pressing force output by the force sensor. This control component has high applicability and versatility.
[0010] Optionally, the control component further includes a display screen; the display screen is electrically connected to the industrial control computer.
[0011] In this embodiment, the display screen can display various signals received or sent by the industrial control computer, thereby facilitating the test personnel to obtain various signals from the display screen and improving the convenience of testing the door testing equipment.
[0012] Optionally, the actuator includes an actuator body and an encoder; both the actuator body and the encoder are electrically connected to the control component.
[0013] The actuator body is mounted on the car door and is positioned opposite the car door switch, and is used to press the car door switch;
[0014] The encoder, mounted on the actuator body, is used to provide feedback to the control component on the pressing distance of the actuator body.
[0015] In this embodiment, when the control component controls the actuator body to press the door switch, the control component collects the pressure value of the force sensor in real time. When the pressure value reaches the set value, the control component will stop the actuator's action. At the same time, the control component calculates the pressing distance in real time through the position pulse number fed back by the encoder. When the pressing distance exceeds the set distance value, the actuator body stops and reverses back to its original position. This prevents damage to the force sensor and control errors that could cause damage to the door switch during the test, thus ensuring the safety and service life of the door testing equipment.
[0016] Optionally, the door testing equipment further includes a force sensor; the force sensor is installed on the actuator at a position opposite to the door switch and is electrically connected to the control component, for detecting the pressing force of the actuator on the door switch.
[0017] In this embodiment, a force sensor can be used to provide feedback on whether the door switch is precisely pressed by the actuator. By analyzing and judging the vehicle's message signals and precisely controlling the door switch operation, the signal logic of the vehicle can be more comprehensively tested and verified, and the actual user's operating conditions can be better simulated.
[0018] Optionally, the door testing equipment further includes a position detection component; the position detection component is installed on at least one of the door and the body, and is used to detect the current position of the door.
[0019] In this embodiment, after the actuator presses the door switch, the position detection component can detect the position of the door, thereby determining whether the door has been correctly opened or closed, further improving the detection accuracy and precision of the door testing equipment.
[0020] Optionally, the position detection component includes a first detection switch and a second detection switch;
[0021] The first detection switch is installed in the fully open position of the car door and is electrically connected to the control component. It is used to be triggered when the car door is fully open to output a fully open signal to the control component.
[0022] The second detection switch is installed in the fully closed position of the door and is electrically connected to the control component. It is used to be triggered when the door is fully closed to output a door fully closed signal to the control component.
[0023] In this embodiment, the first detection switch can detect whether the car door is in a fully open position, and the second detection switch can detect whether the car door is in a fully closed position. Thus, the control component can determine whether the car door is fully open or closed, further improving the detection accuracy and precision of the car door testing device.
[0024] Optionally, the door testing equipment further includes an alarm; the alarm is electrically connected to the control component and is used to issue an abnormal alarm when the control component outputs a door abnormality signal.
[0025] In this embodiment, when the control component detects or receives that the door switch is not pressed correctly, the door does not perform the relevant opening and closing operation correctly, or the vehicle message signal is abnormal, the actuator will stop the relevant pressing operation, and the control component will send a door abnormality signal to the alarm. The alarm will then issue an abnormal alarm, thereby prompting the staff to promptly inspect the door testing equipment.
[0026] Optionally, the door testing equipment further includes a power supply device; the power supply device is electrically connected to the control component.
[0027] In this embodiment, the control component can control the vehicle to perform relevant operation commands; and the power supply device can also monitor the current changes of the vehicle in real time to determine whether the vehicle performs the relevant pressing operation.
[0028] Optionally, the door testing equipment further includes an adapter; the control component is connected to the vehicle controller via the adapter.
[0029] In this embodiment, the control component can more comprehensively test and verify the vehicle's signal logic and better simulate actual user operating conditions by parsing and providing feedback on the vehicle's CANFD (Controller Area Network, Vehicle Bus) messages and precisely controlling the pressing of the door switch.

[0036] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0037] like Figure 1 and Figure 2 As shown in the embodiment of this application, a door testing device is provided for testing the door 8 of a vehicle under test, including an actuator 1 and a control component 2;
[0038] The actuator 1 is installed on the door 8 of the vehicle under test, and is positioned opposite to the door switch of the door 8, for pressing the door switch; it is understood that the actuator 1 includes, but is not limited to, a pressing robot, a pressing pump, etc.; the actuator 1 is installed at the door switch position of the door 8, and the actuator 1 can simulate manually pressing the door switch. After the door switch is pressed by the actuator 1, the door 8 will perform operations such as opening, closing, unlocking, and locking.
[0039] The control component 2 is electrically connected to both the actuator 1 and the vehicle controller 10 of the vehicle under test. It is used to send, receive, and parse vehicle message information based on the vehicle controller 10, and to control the actuator 1 to press the door switch. Understandably, the control component 2 includes, but is not limited to, an industrial control computer 21, a computer, etc.
[0040] In this application, actuator 1 is installed on the door 8 of the vehicle under test and is used to press the door switch. Control component 2 is electrically connected to both actuator 1 and vehicle controller 10. Control component 2 can control actuator 1 to press the door switch. After the door switch is pressed by actuator 1, the door 8 will perform operations such as opening and closing. At the same time, control component 2 can also receive, send and receive, and parse vehicle message signals through vehicle controller 10. Vehicle message signals include vehicle wake-up, door open status, door open / closed status, hidden door handle status, door lock / unlock, and Hall effect data of door drive mechanism. Through vehicle logic, the vehicle message signals are combined with the actions of door 8 to perform a complete closed-loop test process, to determine whether the action of actuator 1 pressing the door switch corresponds to the vehicle message signal, thereby determining whether the door switch can correctly perform the relevant actions after being pressed by actuator 1, and to perform durability testing on door 8. Compared to existing technologies where control components simply involve pressing the door switch via an actuator and do not interact with the vehicle controller, the door testing equipment of this application can directly connect to the vehicle controller 10. It can send, receive, and parse vehicle message signals, achieving a fully automated closed-loop testing scheme for the door 8, thus improving the testing accuracy and precision. Furthermore, this door testing equipment has a simple structure, low manufacturing cost, and convenient operation.
[0041] In one embodiment, such as Figure 2As shown, the door testing equipment also includes a force sensor 3. The force sensor 3 is installed on the actuator 1 opposite to the door switch and is electrically connected to the control component 2. It is used to detect the pressing force of the actuator 1 on the door switch. Understandably, the force sensor 3 can be installed at the output end of the actuator 1 or at the end of the switch facing the actuator 1. During the process of the actuator 1 pressing the door switch, the actuator 1 also squeezes the force sensor 3, thus the force sensor 3 can detect the pressing force of the actuator 1 on the door switch in real time. The control component 2 can receive the pressing force detected by the force sensor 3 and determine whether the door switch is triggered under a preset pressure based on the pressing force detected by the force sensor 3, thereby determining whether the door switch is qualified. Furthermore, the force sensor 3 can provide feedback on whether the door switch is accurately pressed by the actuator 1. By analyzing and judging the vehicle's message signals and precisely controlling the pressing operation of the door switch, the signal logic of the entire vehicle can be more comprehensively evaluated and verified, and actual user usage conditions can be better simulated.
[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the door testing equipment further includes a position detection component 4; the position detection component 4 is installed on at least one of the door 8 and the body 9, and is used to detect the current position of the door 8. Understandably, the position detection component 4 includes, but is not limited to, a trigger switch, a photoelectric sensor, etc.; the position detection component 4 can be installed on the door 8 or the body 9, or simultaneously on both. In this embodiment, after the actuator 1 presses the door switch, the position detection component 4 can detect the position of the door 8, thereby determining whether the door 8 has been correctly opened or closed, further improving the detection accuracy and precision of the door testing equipment.
[0043] In one embodiment, the position detection component 4 includes a first detection switch (not shown in the figure) and a second detection switch (not shown in the figure). The first detection switch is installed in the fully open position of the door 8 and is electrically connected to the control component 2. It is triggered when the door 8 is fully open to output a door 8 fully open signal to the control component 2. The second detection switch is installed in the fully closed position of the door 8 and is electrically connected to the control component 2. It is triggered when the door 8 is fully closed to output a door 8 fully closed signal to the control component 2. Understandably, the first detection switch is located in the fully open position of the door 8 (e.g., the first detection switch is installed on the inner edge of the door 8). When the door 8 is fully open, the door 8 will trigger the first detection switch, which will send a door 8 fully open signal to the control component 2. The second detection switch is located in the fully closed position of the door 8 (e.g., the second detection switch is installed on the inner edge of the door 8). When the door 8 is fully closed, the door 8 will trigger the second detection switch, which will send a door 8 fully closed signal to the control component 2. In this embodiment, the first detection switch can detect whether the car door 8 is in a fully open position, and the second detection switch can detect whether the car door 8 is in a fully closed position. Thus, the control component 2 can determine whether the car door 8 is fully open or closed, further improving the detection accuracy and precision of the car door testing device.
[0044] In one embodiment, such as Figure 1 As shown, the door testing equipment also includes an alarm 5; the alarm 5 is electrically connected to the control component 2 and is used to issue an abnormal alarm when the control component 2 outputs an abnormal signal from the door 8. It can be understood that the alarm 5 includes, but is not limited to, an alarm horn, an alarm light, etc. In this embodiment, when the control component 2 detects or receives that the door switch is not pressed correctly, the door 8 does not correctly perform the relevant opening and closing operation, or the vehicle message signal is abnormal, the actuator 1 will stop the relevant pressing operation, and the control component 2 will send an abnormal signal from the door 8 to the alarm 5, which will then issue an abnormal alarm, thereby prompting personnel to promptly inspect and repair the door testing equipment.
[0045] In one embodiment, such as Figure 2 As shown, the vehicle door testing equipment also includes a power supply device 6; the power supply device 6 is electrically connected to the control component 2. It can be understood that the power supply device 6 includes, but is not limited to, a programmable power supply, etc., and can supply power to the entire vehicle; the power supply device 6 can control the voltage, current, etc., input to the entire vehicle, thereby enabling the control component 2 to control the entire vehicle to perform relevant operating commands; furthermore, the power supply device 6 can also monitor the current changes of the entire vehicle in real time, thereby determining whether the entire vehicle has performed a relevant pressing operation.
[0046] In one embodiment, such as Figure 2 As shown, the door testing equipment also includes an adapter 7; the control component 2 is connected to the vehicle controller 10 through the adapter 7. It is understood that the adapter 7 includes, but is not limited to, a multi-channel USB-CANFD adapter 7; the control component 2 is connected to the vehicle controller 10 through the adapter 7, thereby enabling the control component 2 to more comprehensively assess and verify the vehicle's signal logic and better simulate actual user operating conditions by parsing and providing feedback on the vehicle's CANFD (Controller Area Network, Vehicle Bus) messages and precisely controlling the door opening and closing operations.
[0047] In one embodiment, such as Figure 2 As shown, the control component 2 includes a data acquisition card 22, a motion control card 23, and an industrial computer 21. The industrial computer 21 is electrically connected to the vehicle controller 10. The data acquisition card 22, the motion control card 23, and the actuator 1 are all electrically connected to the industrial computer 21. Understandably, the industrial computer 21 has peripheral interfaces including PCI, PCIE, USB 3.0, and RS232. The motion control card 23 and the data acquisition card 22 are connected via the PCI port, the adapter 7 is connected via the USB 3.0 interface, and the power controller is connected via RS232. Specifically, the industrial computer 21 controls the driver 11 through the motion control card 23 to drive the actuator 1. The force sensor 3 is equipped with a signal amplifier 31, and the force sensor 3 outputs an analog signal (0-10V) to the data acquisition card 22 for acquisition. In this embodiment, the motion control card 23 can control the actuator 1 to press the door switch, and the data acquisition card 22 can acquire the pressing force output by the force sensor 3. This control component 2 has high applicability and versatility.
[0048] In one embodiment, such as Figure 1 As shown, the control component 2 also includes a display screen 24; the display screen 24 is electrically connected to the industrial control computer 21. Understandably, the display screen 24 can display various signals received or sent by the industrial control computer 21, thereby facilitating the testing personnel to obtain various signals from the display screen 24 and improving the convenience of testing with the vehicle door testing equipment.
[0049] In one embodiment, the actuator 1 includes an actuator body and an encoder; both the actuator body and the encoder are electrically connected to the control component 2; the actuator body is mounted on the door 8, opposite to the door switch, and is used to press the door switch; the encoder is mounted on the actuator body and is used to feed back the pressing distance of the actuator body to the control component 2. Understandably, when the control component 2 controls the actuator body to press the door switch, the control component 2 collects the pressure value of the force sensor 3 in real time. When the pressure value reaches a set value, the control component 2 stops the action of the actuator 1. Simultaneously, the control component 2 calculates the pressing distance in real time based on the number of position pulses fed back by the encoder. When the pressing distance exceeds the set distance value, the actuator body stops and reverses back to its original position, preventing damage to the force sensor 3 and control errors that could damage the door switch during the test, thus ensuring the safety and service life of the door testing equipment.
[0050] In summary, as Figure 3 As shown, the testing principle of this car door testing equipment is as follows: The control component 2 obtains the initial state of the vehicle through the vehicle controller 10 and unlocks the vehicle. The control component 2 obtains the vehicle message signal after unlocking the vehicle through the vehicle controller 10, and determines whether the door switch needs to be pressed based on the vehicle message signal after unlocking the vehicle. When the door switch needs to be pressed, the control component 2 presses the door switch through the actuator 1. After the door switch is pressed, the door 8 is in the open state, and the actuator 1 is reset. The control component 2 obtains the vehicle message signal after the door 8 is opened through the vehicle controller 10, and determines whether the door switch needs to be pressed based on the vehicle message signal after the door 8 is opened. When the door is closed, the control component 2 presses the door switch via the actuator 1, and the door 8 is closed after the door switch is pressed, and the actuator 1 is reset. The control component 2 obtains the vehicle message signal after the door 8 is closed through the vehicle controller 10, and determines whether the vehicle needs to be locked based on the vehicle message signal after the door 8 is closed. When the vehicle needs to be locked, the control component 2 locks the vehicle through the vehicle controller. The control component 2 obtains the vehicle message signal after the vehicle is locked through the vehicle controller 10, and determines whether the vehicle needs to be unlocked based on the vehicle message signal after the vehicle is locked. When the vehicle needs to be unlocked, the control component 2 unlocks the vehicle through the vehicle controller 10. This process is repeated.
