Description

Technical Field

[0001] This utility model relates to the field of vehicle testing, specifically a device that reduces manual vehicle steering calibration and durability testing. Background Technology

[0002] In the field of automotive quality inspection, whole vehicle steering tests and stationary steering tests are time-consuming, and many non-mass-produced vehicles used for testing do not have air conditioning systems and cannot cool or heat. However, since whole vehicle tests are generally carried out outdoors, system engineers may suffer personal injury due to harsh environments during outdoor whole vehicle tests in summer or winter. When performing tests such as the fastest steering speed multiple times, testers may experience blisters on their palms or muscle contusions in their arms. In addition, since the external environment is different for each test, the data collected may be affected by human factors. Utility Model Content

[0003] In order to overcome the defects in the prior art, this utility model provides a device for reducing manual vehicle steering calibration and durability testing, which is used to solve one or more of the above problems.

[0004] This application discloses an embodiment of a device for reducing manual vehicle steering calibration and durability testing, comprising: a data acquisition module; a control module located inside the vehicle, the control module having a host computer unit electrically connected to the data acquisition module, a robotic arm unit connected to the host computer unit, and a gripper unit connected to the robotic arm unit, the gripper unit being used to connect to the vehicle steering wheel, the robotic arm unit being able to drive the gripper unit to drive the steering wheel; and a tire lateral sensing module disposed on the vehicle tire and electrically connected to the data acquisition module.

[0005] Furthermore, the data acquisition module is located outside the driver's side door, on the driver's seat, or on the passenger seat of the vehicle.

[0006] Furthermore, the robotic arm unit includes a robotic arm base fixedly connected to the upper end of the host computer unit and a robotic arm body rotatably connected to the upper end of the robotic arm base. The end of the robotic arm body away from the robotic arm base is connected to the gripper unit, and the robotic arm body can drive the gripper unit to rotate.

[0007] Furthermore, the end of the robotic arm body away from the robotic arm base has a rotary servo motor, which is connected to the center of the gripper unit.

[0008] Furthermore, the claw unit has a fixed base connected to the center of the rotary servo motor and three claws located on the end face of the fixed base away from the rotary servo motor. The three claws are evenly distributed along the circumferential direction on the end face of the fixed base.

[0009] Furthermore, the fixed base has three equally spaced sliding grooves extending radially outward from its center, and the three claw members are respectively threadedly connected to the three sliding grooves.

[0023] like Figures 1 to 4 A device for reducing manual vehicle steering calibration and durability testing includes:

[0024] The data acquisition module 1 is used to collect data from the vehicle during the testing process. It also collects data from the control module 3 and sensors, thereby gathering data on the steering wheel and vehicle during the testing process. In this embodiment, the data acquisition module 1 is connected to the tire lateral sensing module 2, enabling it to collect data on the vehicle's tire steering process. Of course, in other optional embodiments, the data acquisition module 1 can also be connected to other sensors as needed.

[0025] A control module 3, located inside the vehicle, comprises a host computer unit 31 electrically connected to the data acquisition module 1, a robotic arm unit 32 connected to the host computer unit 31, and a gripper unit 33 connected to the robotic arm unit 32. The gripper unit 33 is connected to the vehicle steering wheel 4. The robotic arm unit 32 drives the gripper unit 33 to drive the steering wheel, thereby enabling the gripper unit 33 to synchronously control and drive the steering wheel 4 to rotate, thus controlling the vehicle to complete the test. The host computer unit 31 is connected to a power source, thereby controlling the robotic arm unit 32 and the gripper unit 33 via electrical signals, and thus controlling the vehicle steering wheel 4. Simultaneously, it can transmit the steering wheel control signals to the data acquisition module 1. In this embodiment, the robotic arm unit 32 is a 4-degree-of-freedom robotic arm with a load capacity of 100N. This allows the position of the gripper unit 33 to be adjusted according to the position of the steering wheel while the position of the control module 3 is fixed, thus enhancing the compatibility with the position of the car steering wheel 4. Of course, in other optional methods, the robotic arm unit 32 can also use other structures that can achieve the same effect.

[0026] Tire lateral sensing module 2 is mounted on the vehicle tire and electrically connected to the data acquisition module 1. The tire lateral sensing module 2 is used to collect the steering force and steering angle information of the tire and transmit the information to the data acquisition module 1.

[0027] In this embodiment, after placing the control module 3 inside the vehicle and connecting it to the data acquisition module 1, the gripper unit 33 is fixedly connected to the vehicle steering wheel 4 to control the steering wheel via the gripper unit 33. Then, the wiring harness, thermocouple, and sensors are connected, and a power-on test is performed. Afterwards, the head motor of the robotic arm unit 32 performs a self-test to verify rotational centering. Next, a test program is set in the control module 3, and the test begins, with data recorded via the data acquisition module 1. In this embodiment, the tests that can be performed include motorless main steering test, power steering calibration, power steering torque verification, steering temperature rise test, stationary endurance test, maximum hand speed test, and torque and center position self-learning.

[0028] The above structure eliminates the need for manual testing on the vehicle, reducing the time engineers spend on data collection. It can reliably replace manual testing due to insufficient speed and avoids issues such as blisters on the hands or muscle contusions in the arms of testers. It also prevents personal injury caused by harsh environments, making the collected data more stable and reliable.

[0029] Specifically, the data acquisition module 1 is located outside the driver's side door, on the driver's seat, or on the passenger seat. That is, the data acquisition module 1 can be placed inside the car together with the control module 3, or it can be placed outside the car after being electrically connected to the control module 3 via wired or wireless means, so that the data acquisition module 1 can be placed according to actual needs.

[0030] Specifically, the robotic arm unit 32 includes a robotic arm base 321 fixedly connected to the upper end of the host computer unit 31, and a robotic arm body 322 rotatably connected to the upper end of the robotic arm base 321. The end of the robotic arm body 322 away from the robotic arm base 321 is connected to the gripper unit 33. The robotic arm body 322 can drive the gripper unit 33 to rotate, so that after the robotic arm body 322 drives the gripper unit 33 to rotate, it can simultaneously drive the car steering wheel 4 connected to the gripper unit 33 to rotate. After the robotic arm base 321 is fixedly connected to the host computer unit 31, relative movement between the robotic arm base 321 and the host computer unit 31 can be avoided, thereby providing better support for the robotic arm body 322. Since the robotic arm base 321 is located above the host computer unit 31, the weight of the robotic arm body 322 and the gripper unit 33 is concentrated on the upper surface of the host computer unit 31, making the robotic arm body 322 and the gripper unit 33 more stable during use. In this embodiment, the robotic arm base 321 and the host computer unit 31 are connected by screws, allowing for easy disassembly while maintaining good stability.

[0031] Specifically, the end of the robotic arm body 322 away from the robotic arm base 321 has a rotary servo motor 323. The rotary servo motor 323 is connected to the center of the gripper unit 33. That is, the rotation of the rotary servo motor 323 drives the gripper unit 33 to rotate from the center of the gripper unit 33, thereby enabling the car steering wheel 4 connected to the gripper unit 33 to rotate synchronously with the gripper unit 33. This achieves the effect that the rotary servo motor 323 and the car steering wheel 4 rotate at the same angular velocity, resulting in high rotational accuracy of the steering wheel.

[0032] Specifically, the claw unit 33 has a fixed base 331 connected to the center of the rotary servo motor 323, and three claws 332 located on the end face of the fixed base 331 away from the rotary servo motor 323. The three claws 332 are evenly distributed along the circumferential direction on the end face of the fixed base 331. Thus, the three claws 332 achieve a good fixing effect on the car steering wheel 4 along the circumferential direction. Preferably, the fixed base 331 has three equally spaced fixed bases 3311 extending radially outward from its center. The three claws 332 are threadedly connected to the three fixed bases 3311 respectively, and the claws 332 can be connected to different positions within the fixed bases 3311. By connecting the claws 332 to different positions within the fixed bases 3311, compatibility with different specifications of car steering wheels 4 can be achieved, improving adaptability to different vehicles.

[0033] Specifically, the control module 3 includes a thermocouple interface 34 and a communication line connector 35. This enables thermocouple data acquisition and interconnection with different external devices.

[0034] Specifically, it also includes a power module, which includes a power switch 5 and an emergency stop switch 6 integrated on the control module 3. The power switch 5 controls the operation of the entire device, and the emergency stop switch 6 protects the device in times of crisis, thereby enhancing the safety of the entire device.

At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the utility model.
