[0025] Embodiment 1

[0026] Referring to Figure 1-6 , an embodiment provided by the present utility model: A test device for simulating a flat tire of an automobile, including a data acquisition integrated control box 1, which is internally provided with control components. The control components include a signal transmitter, a signal receiver, and a data storage unit. The data acquisition integrated control box 1 is internally provided with a tire pressure monitoring module 2 and a tire speed monitoring module 3. One end surface of the bottom of the data acquisition integrated control box 1 is provided with a cutter shaft 4. One end of the cutter shaft 4 is provided with a magnetic switch 5. The bottom surface of the cutter shaft 4 is provided with a rotary cutter 6. One side surface of the rotary cutter 6 is provided with a compression spring 7. One end surface of the compression spring 7 is provided with a spring mounting plate 8. The bottom surface of the rotary cutter 6 is provided with a connecting plate 9. The bottom surface of the connecting plate 9 is provided with a device mounting plate member 10.

[0027] The data acquisition integrated control box 1 is fixedly connected to both the tire pressure monitoring module 2 and the tire speed monitoring module 3. The tire pressure monitoring module 2 and the tire speed monitoring module 3 are electrically connected to the main control board inside the data acquisition integrated control box 1. The data acquisition integrated control box 1 is provided as a rectangular box body.

[0028] One end surface of the cutter shaft 4 is fixedly connected to the data acquisition integrated control box 1, and the other end is fixedly connected to the connecting plate 9 through a bearing. The data acquisition integrated control box 1 and the magnetic switch 5 are fixedly connected. The cutter shaft 4 and the rotary cutter 6 are fixedly connected. The rotary cutter 6 can rotate around the cutter shaft 4.

[0029] One end surface of the compression spring 7 is fixedly connected to the spring mounting plate 8, and the other end surface is fixedly connected to the rotary cutter 6. The spring mounting plate 8 and the connecting plate 9 are fixedly connected. The connecting plate 9 is fixedly connected to the device mounting plate member 10 through a plurality of bolts. The device mounting plate member 10 is provided with a plurality of long holes in the horizontal direction, and the position between the device mounting plate member 10 and the connecting plate 9 can be adjusted.

[0030] Specifically, its structure is formed by a data acquisition integrated control box 1, a tire pressure monitoring module 2, a tire speed monitoring module 3, a cutter shaft 4, a magnetic switch 5, a rotary cutter 6, a compression spring 7, a spring mounting plate 8, a connecting plate 9, and a device mounting plate member 10 to form a test device for simulating a tire blowout of an automobile. The device mounting plate member 10 is vertically installed on the inner tire crossbeam through a plurality of bolts. The magnetic switch 5 is installed at the bottom end of the data acquisition integrated control box 1. A through hole is provided at one end of the rotary cutter 6 away from the rotary cutter 6.

[0031] Control principle of the test device for simulating a tire blowout of an automobile: During the dynamic test of the tire, in the automatic mode, the actual situation of the tire can be obtained in real time through the tire pressure monitoring module 2 and the tire speed monitoring module 3, and the detected data is transmitted to the industrial control computer. The industrial control computer calculates the rotational speed of the rotary cutter in real time according to the transmitted tire pressure and tire speed data, and transmits it to the controller through the CAN bus. After receiving it, the controller controls the rotary cutter 6 to rotate to complete the operation of simulating a tire blowout. As Figure 6 shown, in the manual mode, the tire pressure monitoring module 2 and the tire speed monitoring module 3 obtain the dynamic information of the tire and transmit the data to the data display in real time. The operator observes the data on the display. When the required test value is reached, the operator controls the terminal of the magnetic switch 5 through the remote control. Under the action of the compression spring 7, the rotary cutter 6 rotates around the cutter shaft 4 to complete the operation of simulating a tire blowout, enabling the whole to quickly deflate the automobile tire and effectively simulating the blowout test, improving safety and reliability.

[0032] Rotary cutter regulation model:

[0033] (Rotary Cutter Speed)=F(Tire Pressure,Tire Speed)

[0034] Wherein: Tire Pressure is the tire pressure; Tire Speed is the tire speed; Rotary Cutter Speed is the rotary cutter rotation speed; F is the functional relationship among the tire pressure, the tire speed and the rotary cutter rotation speed.
