Description

Technical Field

[0001] The invention belongs to the technical field of simulation devices, and particularly relates to a driving active deflation simulation tire blowout device and a working method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the modern automotive industry, vehicle safety performance is one of the core indicators for measuring product quality, and testing vehicle handling and stability in the event of a sudden tire blowout is a key step in ensuring road traffic safety. Traditional vehicle tire blowout tests mainly simulate tire blowouts by mechanically destroying the tire structure or using pre-damaged tires. Although such methods can trigger tire blowout scenarios, they have significant technical limitations. In terms of tire blowout location control, existing devices are difficult to accurately locate specific wheels or specific areas of tires, resulting in a high degree of randomness in the location of tire blowouts during the test. This makes it impossible to reproduce the differentiated effects of tire blowouts on different wheel conditions on the vehicle's driving state, seriously affecting the consistency and accuracy of test data.

[0004] Because the testing process directly damages the tire structure, new tires must be replaced after each test. This not only increases tire procurement costs but also prolongs test preparation time. Frequent tire replacements lead to excessively long test cycles, especially when conducting multiple comparison tests or long-term reliability testing. This significantly increases time and material costs, hindering test efficiency and making it difficult to adapt to the rapid testing needs of automotive R&D. Summary of the Invention In response to the above problems, the present invention provides a driving active deflation simulation tire blowout device and working method, which solves the problem that existing tire blowout test devices cannot accurately control the tire blowout position, resulting in inaccurate test results, and the problem that traditional devices directly damage the tire during testing, resulting in low test efficiency and high test costs.

[0013] As a further implementation, the air suction cup consists of a fixed bracket and two suction cups, the top end of the fixed bracket is connected to the cross bar in a relatively movable manner, and the two suction cups are arranged side by side at the bottom end of the fixed bracket.

[0014] In a second aspect, the present invention further provides a method for operating a device for actively deflation of a tire during driving to simulate a tire blowout, comprising the following steps: S1.

In addition, it should be understood that when the terms "include" and / or "comprising" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations; Currently, in vehicle safety performance tests, tire blowout tests are an important step in evaluating the vehicle's handling and stability in the event of a sudden tire blowout. Existing tire blowout test devices are usually unable to accurately control the location of the tire blowout, resulting in inaccurate test results. Traditional devices directly damage the tire during testing when a tire blows, seriously affecting the efficiency and cost of the test. The following will be described in detail with reference to the accompanying drawings. The present invention provides a device for actively deflation simulating a tire blowout while driving, aiming to address the deficiencies in the prior art and capable of accurately controlling a certain wheel to repeatably actively deflate and simulate a tire blowout scenario. The following will be described in detail with reference to the accompanying drawings. A device for actively deflation simulating a tire blowout while driving provided by the present invention is provided.

[0023] Example 1 This embodiment provides a device for simulating tire blowout by actively deflation during driving. Figure 1-Figure 3 As shown, it includes: a wheel bolt sleeve 2, an air chamber 4, a sliding sealing assembly 5, a pipe connector 6 and a support bracket 9; the wheel bolt sleeve 2, the air chamber 4, the sliding sealing assembly 5, and the pipe connector 6 are connected and arranged in sequence, the wheel bolt sleeve 2 is installed on the wheel and rotates with the wheel, the sliding sealing assembly 5 is arranged between the air chamber 4 and the pipe connector 6, so that the air chamber 4 and the pipe connector 6 can rotate relative to each other, and can ensure that the air chamber 4 and the pipe connector 6 are sealed and can be relatively rotatably connected, the pipe connector 6 is connected to the vehicle body through the support bracket 9, and the support bracket 9 is used to fix the pipe connector 6 to the vehicle body; the air chamber 4 is connected to the inside of the tire through the air pipe 1, and is used to inflate and deflate the tire. The simulated tire blowout device described in this embodiment can accurately control the deflation of a certain wheel or several wheels during vehicle testing, while ensuring that other wheels are not affected. Since the tires are not damaged, they only need to be inflated again when repeating the test. An air pressure sensor is also installed on the device to detect the pressure changes of the wheels during the deflation process in real time, thereby improving the accuracy and efficiency of the test and reducing the test cost. The device can be installed on four wheels, and the electromagnetic valve 8 can be used to arbitrarily match and realize the simulated tire blowout of one, two, three or even four wheels through single-wheel control.

A wheel bolt sleeve 2 is provided at one end of the air chamber 4, allowing the air chamber 4 to rotate synchronously with the wheel bolt sleeve 2, thereby creating conditions for the air tube 1 to be continuously connected to the tire. A pipe connector 6 is provided at the other end of the air chamber 4 for connecting to an external air pump or inflation / deflation system with a high gas flow rate. Multiple air tubes 1 are provided on the side of the air chamber 4. In this embodiment, six air tubes 1 are used as an example. The specific number of air tubes 1 is determined by the size of the tire. The larger the tire, the more air tubes 1 are required to achieve instant deflation and more realistically simulate a tire blowout. An air port connector is provided at one end of the air tube 1, connecting to the air chamber 4, and a quick plug is provided at the other end, which plugs into the wheel rim. The modular design of the air tube 1 allows for independent replacement of individual air tubes in the event of damage, reducing maintenance costs.

[0025] As a further implementation method, there are multiple wheel bolt sleeves 2, which are arranged and fixedly connected to the nuts of the bolts on the wheels, and are arranged at one end of the air chamber 4 through a disc 3. Multiple wheel bolt sleeves 2 are evenly arranged along the circumference of the disc 3. One end of the wheel bolt sleeve 2 is detachably provided with a bolt sleeve, and the other end is fixedly connected to the disc 3; the bolt sleeve is connected to the nut of the wheel bolt.

The number of waist holes 12 needs to be no less than six. The length direction of the waist holes 12 passes through the center of the disc 3.

The plurality of waist holes 12 are evenly arranged along the circumference of the disc 3. The circumferentially evenly distributed waist holes 12 and the symmetrical layout can reduce the dynamic imbalance of the disc 3 caused by uneven mass distribution, thereby ensuring stability during high-speed rotation.

[0027] As a further implementation method, an air pressure sensor 7 is provided on the pipe connector 6 for monitoring the changes in tire air pressure during the entire test process; an electromagnetic valve 8 is provided at one end of the pipe connector 6 away from the sliding sealing assembly 5 for controlling the closing and release of the gas in the entire pipeline.

[0028] As a further implementation method, the support bracket 9 is composed of a vertical rod and a horizontal rod, one end of the vertical rod is fixedly connected to the pipe connector 6, one end of the horizontal rod is movably set on the vertical rod, and the other end of the horizontal rod is provided with an air suction cup 10; the air suction cup 10 can move along the axial direction of the horizontal rod; the support bracket 9 is used to fix the entire device to avoid rotation of the pipe connector 6, air path and line during the test, and the multi-level adjustment of the vertical rod and the horizontal rod is coordinated with the displacement of the air suction cup 10, which can adapt to different pipe diameters and complex curved surface installation environments, and solve the problem of single positioning of traditional brackets; the suction cup sliding design allows fine-tuning of the installation position to avoid installation interference caused by pipeline layout offset.

[0029] As a further implementation method, the vertical rod and the horizontal rod are both telescopic rods, and the horizontal rod and the vertical rod are provided with a locking device, which can be locked and fixed at any length position, so that the support bracket 9 can adapt to different vehicle models and can adsorb the air suction cup 10 at a suitable position on the vehicle body to ensure the stability of the support bracket 9; the switch control line of the solenoid valve 8 is arranged in the vertical rod and the horizontal rod and passes into the vehicle to be connected to the switch of the solenoid valve 8, and the operator controls the solenoid valve 8 in the vehicle.

[0030] As a further implementation method, the air suction cup 10 consists of a fixed bracket and two suction cups. The top of the fixed bracket is connected to the cross bar in a relatively movable manner. The two suction cups are arranged side by side at the bottom end of the fixed bracket. The air suction cup 10 is pressed and adsorbed at the same time, which is 70% more efficient than the bolt fixing method. It is especially suitable for maintenance scenarios with frequent disassembly and assembly; the modular structure supports manual operation without the need for additional tools, reducing labor costs.

The wheel bolt sleeve 2 is fixed to the wheel bolt, the quick plug is connected to the wheel rim, and the switch control line is connected to the solenoid valve 8 switch; S2. When the vehicle reaches a predetermined state, the solenoid valve 8 is opened via the switch control line. The air in the tire is instantly released, achieving the effect of a tire blowout. By deflation, the tire blowout scenario is simulated without damaging the tire. The test can be repeated in a very short time, saving time and material costs. S3. After the test is completed, the solenoid valve 8 is closed and the tire is inflated. The air pressure sensor 7 continuously monitors the internal air pressure data of the tire, so that the vehicle returns to its initial state. The tire blowout scenario is simulated by deflating the tire. The test will not cause damage to the tire and can be repeated in a very short time, saving time and material costs and facilitating the next test.
