[0002] At present, vehicle tire blowout is considered to be the number one killer on highways. Domestic major vehicle manufacturers have successively installed tire blowout emergency safety devices and tire pressure detection systems in the tires of test vehicles. In order to test whether their reliability can meet the requirements of relevant national standards, it is necessary for major vehicle manufacturers to conduct relevant simulation tests of tire blowout on experimental vehicles.

[0003] At present, the traditional method of simulating deflation of tire blowout is to puncture and deflate the tire tread with the help of a tire breaker, so that the wheel is pressed against the triangular blade and pierced, and then the gas is leaked from the punctured hole in the tire tread, thereby achieving the purpose of simulating rapid deflation (tire blowout) of the vehicle. However, this method has certain risks, and it is necessary to punch holes in the road surface to fix the tire breaker before use, which causes certain damage to the road surface, and the installation efficiency is low. For tires of different specifications, there is a situation where the tire cannot be effectively deflated. It is inconvenient to use, cumbersome to operate, time-consuming and labor-intensive, and has low work efficiency, which increases the scientific research experiment time and reduces the performance.

[0004] Based on this, an electronically controlled tire rapid deflation device is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 3 As shown, an electronically controlled tire rapid deflation device includes a rim 100 and a tire 101. The outer side of the rim 100 is provided with a mounting area for mounting the tire 101. The surface of the rim 100 is provided with an annular air cavity 203. The surface of the rim 100 is provided with an electronic control unit 300. The electronic control unit 300 is connected to the deflation component. The rim 100 is provided with an inflation component.

[0025] A bracket 202 is provided on the surface of the rim 100, and an annular air cavity 203 is provided on the bracket 202. A plurality of air tubes 200 are provided on the circumference of the inner wall of the rim 100. One end of the air tube 200 passes through the rim 100 and extends to the inside of the tire 101. A sealing gasket is provided at the connection between the air tube 200 and the tire 101. The material of the sealing gasket is set to rubber material. The sealing gasket and the tire 101 are patched by glue. A mounting head 201 is provided at the other end of the air tube 200. The mounting heads 201 are all connected to the annular air cavity 203. When in use, the mounting head 201 is used to install the plurality of air tubes 200 on the annular air cavity 203, so that the annular air cavity 203 is connected with the inside of the tire 101 through the air tube 200, and the sealing gasket is provided to seal the connection between the air tube 200 and the tire 101 to prevent the tire 101 from deflation.

[0026] A fixing plate 301 is disposed on the surface of the electronic control unit 300 . The fixing plate 301 is provided with mounting holes 302 . Bolts 303 are disposed inside the mounting holes 302 . When in use, the electronic control unit 300 can be fixed on the rim 100 by the bolts 303 .

[0027] The deflation component includes a deflation valve 204, which is installed on the annular air cavity 203. The deflation valve 204 is connected to the annular air cavity 203. Two cavities 205 are provided on the deflation valve 204. A connector 306 is provided on the surface of one side cavity 205. A connecting block 304 is provided on the surface of the electronic control unit 300. A connecting pipe 305 is provided on the connecting block 304. The end of the connecting pipe 305 is connected to the connector 306. When in use, the staff remote control device sends a command to the inside of the electronic control unit 300, so that the electronic control unit 300 releases the gas inside the cavity 205 on one side of the deflation valve 204 through the connecting pipe 305, thereby generating a pressure difference between the two cavities 205 inside the deflation valve 204. At this time, the deflation valve 204 is opened, so that the gas in the tire 101 is discharged through the annular cavity 203 via the deflation valve 204, thereby achieving the function of rapid air leakage.

[0028] The inflation component includes a connecting plate 307, which is arranged on the surface of the deflation valve 204. An inflation valve 308 is provided on the connecting plate 307. The input end of the inflation valve 308 is connected to an inflation tube 309. The end of the inflation tube 309 extends to the inside of the annular air cavity 203. A one-way valve 310 is provided in the middle of the inflation tube 309. When in use, the air pump is connected through the inflation valve 308, and then the air pump is started to inflate the inside of the annular air cavity 203 through the inflation tube 309. A plurality of air tubes 200 are provided in the inside of the annular air cavity 203, so that the gas enters the inside of the tire 101 to inflate the tire 101. Moreover, since the annular air cavity 203 is connected to the deflation valve 204, the gas enters the two cavities 205 in the deflation valve 204, so that the internal pressures of the two cavities 205 are the same, thereby making the deflation valve 204 in a closed state.

[0029] The above embodiment discloses an electronically controlled tire rapid deflation device. When the device is used, the electronic control unit 300 can be fixed on the rim 100 by means of bolts 303, and then a plurality of air pipes 200 are installed on the annular air cavity 203 by means of the mounting head 201, so that the annular air cavity 203 is connected with the inside of the tire 101 through the air pipes 200, and a sealing gasket is provided to seal the connection between the air pipe 200 and the tire 101 to prevent the tire 101 from deflation. Before testing, it is first necessary to connect an air pump through an inflation valve 308, and then start the air pump to inflate the inside of the annular air cavity 203 through an inflation pipe 309, and a plurality of air pipes 200 are provided on the inside of the annular air cavity 203 so that gas enters the inside of the tire 101 to deflate the tire. The tire 101 is inflated, and because the annular air cavity 203 is connected to the deflation valve 204, the gas enters the two cavities 205 in the deflation valve 204, so that the internal pressures of the two cavities 205 are the same, so that the deflation valve 204 is in a closed state, which is convenient for testing. During the test, when the vehicle reaches the specified speed, the staff remote control device sends a command to the inside of the electronic control unit 300, so that the electronic control unit 300 releases the gas inside the cavity 205 on one side of the deflation valve 204 through the connecting pipe 305, thereby causing a pressure difference between the two cavities 205 inside the deflation valve 204. At this time, the deflation valve 204 opens, so that the gas in the tire 101 is discharged through the annular cavity 203 and the deflation valve 204, thereby achieving the function of rapid air leakage.
