[0047] Example

[0048] The technical problem to be solved by the present invention is that: currently, when automobile developers conduct real vehicle testing, testers are required to frequently start the vehicle or input brake or throttle signals to complete the start-up of electrical appliances in the vehicle cabin, etc. Generally, one engineer is required to complete the start-up in the main driver's seat, and another engineer is required to be next to the electrical appliance to observe the phenomenon in the first place to solve the problem. This method is labor-intensive, and manual accelerator or brake pedaling is prone to errors.

[0049] In order to solve the above technical problems, this embodiment provides an automobile testing device, such as Figures 1 to 3 As shown, it includes: a base 1, a pressing structure 2 and a control structure 3.

[0050] The base 1 includes: a base 11 and a mounting plate 12, and the mounting plate 12 is a steel plate. Figure 1 As shown, the base 11 is placed horizontally, and the mounting plate 12 is fixed horizontally on the top surface of the base 11. The mounting plate 12 is provided with a plurality of mounting holes 121 of different specifications. The mounting holes 121 are all threaded holes, and the pressing structure 2 and the control structure 3 are fixed on the mounting plate 12 by the cooperation of the hexagonal bolts with the mounting holes 121. Figure 2 and Figure 3As shown, the base 11 is formed of four steel columns connected end to end to form a rectangular frame structure. Each steel column is installed on the bottom surface of the mounting plate 12 and is arranged close to the edge of the mounting plate 12 to support the mounting plate 12.

[0051] like Figure 1 As shown, the pressing mechanism includes: a bracket 21, a driving member 22 and a rotating arm 23. The bracket 21 includes a base plate and a support portion, both of which are made of aluminum alloy. The base plate is a rectangular plate, and a through hole is opened on the base plate corresponding to the mounting hole 121. A hexagonal screw or a hexagonal bolt is passed through the through hole and installed in the mounting hole 121 to fix the base plate on the mounting plate 12. A supporting portion is fixed in the middle position of the top plate of the base plate. The base plate and the supporting portion can be integrally formed into a bracket 21. The driving member 22 is fixed to the left side of the top of the supporting portion. The driving member 22 is a rotating motor, which is a standard 24VDC-6A servo motor with a peak torque of 12Nm. It is electrically connected to the control module 32 through a connector for control and provides torque to the rotating arm 23. The output shaft of the driving member 22 passes through the supporting part toward the right side and extends to the right side of the supporting part. One end of the rotating arm 23 is fixed on the output shaft of the driving member 22. The entire rotating arm 23 is initially placed obliquely upward and away from the base 1. The rotating arm 23 body is made of aluminum alloy, with a length of 10 cm, and is directly connected to the rotating shaft of the driving member 22 by screws. In the initial state, a silicone pad 4 is installed on the lower end surface of the rotating arm 23 near the end of the car pedal. The silicone pad 4 simulates a person's shoes and directly acts on the accelerator or brake pedal. A sensor 5 is installed on the upper end surface of the rotating arm 23 near the end of the car pedal. The sensor 5 is an IMU module. The IMU module is fixed on the upper end of the rotating arm 23 by screws, and is connected to the control module 32 through a USB interface. The IMU is a nine-axis IMU module with a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer. The gyroscope range is ±2000° or s, the acceleration range is ±8g, the magnetometer range is ±1.3Gauss, and the angle accuracy is static 0.1 and dynamic 0.5. It is used to monitor the position of the rotating arm 23 in real time, and the IMU module performs well in zero drift and temperature drift, has high stability, and can work more accurately under different environmental conditions; and the use of a unique algorithm can reduce the adverse effects of the surrounding magnetic field on it, so that it can operate normally in a complex environment with a magnetic field, reduce errors or failures caused by magnetic field interference, and ensure the reliable realization of its own functions. The bracket 21 is detachably mounted on the base 1, and different brackets 21 can be disassembled and installed to match the driver and the rotating arm 23, which can be adapted to different models. The staff only needs to carry different brackets 21, which is convenient to carry and use, simplifies the workflow of simultaneously detecting different models, and improves work efficiency.

[0052] like Figure 1As shown, the control structure 3 includes: a control module bracket 31 and a control module 32. The control module bracket 31 is set to an inverted U shape, and mounting holes are provided on both sides. The control module bracket 31 can be fixed on the mounting plate 12 by passing a hexagonal screw or a hexagonal bolt through the mounting hole and then installed in the mounting hole 121. Specifically, two control module brackets 31 are provided, and the two control module brackets 31 are arranged opposite to each other. The two control module brackets 31 open downward, and form an installation space with the mounting plate 12. The control module 32 is installed in the installation space, and preferably the control module 32 is fixed on the control module bracket 31. The control module 32 is a Raspberry Pi module, and the Raspberry Pi screen can be operated by touch screen. Different programs can be selected for testing, which simplifies the operation steps.

[0053] In this embodiment, if Figure 1 As shown, the automobile test device also includes a transformer 6, which is installed on the base 1. The input end of the transformer 6 is connected to the automobile power supply. Specifically, the transformer 6 is connected to the cigarette lighter in the car, and the output end of the transformer 6 is connected to the control module 32 and the driver 22. The 12V electricity taken from the cigarette lighter in the car can be generated into 24V for the driver 22 and the control module. The control module 32 is connected to the sensor 5. In some other possible implementations, power can also be taken from outside and adjusted to 24V power supply for the driver 22 and the control module through the transformer 6.

[0054] When the accelerator or brake pedal of the car needs to be tested, the control software can be compiled in advance according to the instructions and imported into the control module 32. The control module 32 controls the start of the driving member 22, and the driving member 22 drives the rotating arm 23 to rotate. The rotating arm 23 moves downward away from the end of the driving member 22 until the silicone pad 4 is placed on the accelerator pedal or the brake pedal. The control module 32 continues to control the rotating arm 23 of the driving member 22 to rotate and press the accelerator pedal or the brake pedal. In this process, the control module 32 can obtain the data of the sensor 5 to obtain the position of the sensor 5, and realize accurate control of the torque, speed and rotation angle to realize the accurate control signal of the brake pedal or the accelerator pedal. At the same time, the staff can observe the corresponding phenomena of the electrical appliances in the car according to the data transmitted by the controller outside the car. Through the control of the controller, the developers can complete the actual vehicle test under different working conditions and automatically record the test data of each time.

[0055] Through the above arrangement, it is only necessary to place the automobile testing device at the main driving position in the vehicle and place the silicone pad 4 corresponding to the brake pedal or the accelerator pedal. No additional staff is required, thus freeing up manpower.

[0056] In this embodiment, if Figure 1As shown, the automobile testing device further includes a counterweight 7, which is mounted on the base 1. Specifically, the counterweight 7 is mounted on the side of the base 1 away from the automobile pedal, so that the entire device can be stably placed under the main driver to prevent rollover when the rotating arm 23 presses the automobile pedal.

[0057] In this embodiment, if Figure 1 As shown, the automobile testing device further includes a handle 8, two handles 8 are provided, and the two handles 8 are suitable for being installed on both sides of the base 1 to facilitate the staff to take it.
