Description

Technical Field

[0001] This utility model belongs to the field of simulation device technology, specifically relating to a vehicle active deflation simulation tire blowout device. Background Technology

[0002] The statements in this section are merely background information related to this utility model 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 under sudden tire blowout conditions is a crucial aspect of ensuring road traffic safety. Traditional vehicle tire blowout tests mainly simulate blowouts by mechanically damaging the tire structure or using pre-damaged tires. While these methods can trigger blowout scenarios, they have significant technical limitations. Regarding blowout location control, existing devices struggle to accurately pinpoint specific areas of a particular wheel or tire, resulting in high randomness in blowout location during testing. This makes it impossible to reproduce the differentiated impacts of different wheel blowouts on vehicle driving conditions, severely affecting the consistency and accuracy of test data.

[0004] Because the testing process directly damages the tire structure, a new tire must be replaced after each test, which not only increases tire procurement costs but also extends test preparation time. Frequent tire replacements lead to excessively long test cycles, especially when conducting multiple comparative tests or long-term reliability tests. This results in a sharp increase in time and material costs, hindering the improvement of testing efficiency and making it difficult to meet the rapid testing needs in automotive R&D. Utility Model Content To address the aforementioned problems, this utility model provides a vehicle active deflation simulation tire blowout device, which solves the problems of existing tire blowout testing devices being unable to accurately control the blowout location, resulting in inaccurate test results, as well as the problems of traditional devices directly damaging the tire during a blowout test, leading to low testing efficiency and high testing costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a vehicle active deflation device to simulate tire blowout, comprising: a wheel bolt sleeve, an air chamber, a sliding sealing assembly, a pipe connector, and a support bracket; the wheel bolt sleeve, air chamber, sliding sealing assembly, and pipe connector are sequentially connected and arranged; the wheel bolt sleeve is installed on the wheel and rotates with the wheel; the sliding sealing assembly is provided between the air chamber and the pipe connector, allowing relative rotation between the air chamber and the pipe connector; the pipe connector is connected to the vehicle body through the support bracket; the air chamber is connected to the inside of the tire through an air pipe.

[0006] As a further implementation, the air chamber has a cylindrical structure, with a wheel bolt sleeve at one end and a pipe connector at the other end. Multiple air pipes are provided on the side of the air chamber, and the number of air pipes is determined according to the size of the tire.

[0007] As a further implementation, one end of the air pipe is provided with an air inlet connector that connects to the air chamber, and the other end is provided with a quick plug that is plugged into the rim of the wheel.

[0008] As a further implementation, there are multiple wheel bolt sleeves, which are disposed at one end of the air chamber via a disc. The multiple wheel bolt sleeves are evenly arranged around the circumference of the disc. One end of each wheel bolt sleeve is detachably provided with a bolt head, and the other end is fixedly connected to the disc. The bolt head is connected to the nut of the wheel bolt.

[0009] As a further implementation, the wheel bolt sleeve is connected to the disc by fasteners. The disc is provided with a plurality of waist holes, the length direction of which all pass through the center of the disc, and the plurality of waist holes are evenly arranged along the circumference of the disc.

[0010] As a further implementation, a pressure sensor is provided on the pipeline connector to monitor the tire pressure changes throughout the test; a solenoid valve is provided at the end of the pipeline connector away from the sliding sealing assembly to control the closing and release of gas in the entire pipeline.

[0011] As a further implementation, the support bracket consists of a vertical rod and a horizontal rod. One end of the vertical rod is fixedly connected to the pipeline connector, one end of the horizontal rod is movably mounted on the vertical rod, and the other end of the horizontal rod is provided with an air suction cup; the air suction cup can move along the axial direction of the horizontal rod.

[0012] As a further implementation, both the vertical and horizontal bars are telescopic bars, and locking devices are provided in the vertical and horizontal bars to lock and fix them at any length position; the switch control line of the solenoid valve is arranged in the vertical and horizontal bars and passes through the vehicle to connect with the solenoid valve switch.

[0013] As a further implementation, the air suction cup consists of a fixed bracket and two suction cups, the top of the fixed bracket being movable relative to the crossbar, and the two suction cups being arranged side by side at the bottom of the fixed bracket.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are: This invention involves installing a wheel bolt sleeve on the wheel and allowing it to rotate with the wheel. A sliding sealing assembly is provided between the air chamber and the pipe connector, enabling relative rotation between the air chamber and the pipe connector while ensuring a sealed connection. The pipe connector is connected to the vehicle body via a support bracket, which secures the pipe connector to the vehicle body. The air chamber is connected to the inside of the tire via an air pipe for inflating and deflating the tire. During vehicle testing, it allows for precise control of deflating one or several wheels while ensuring that other wheels are unaffected. Because the tires are not damaged, repeated testing only requires re-inflating. The device also includes a pressure sensor to monitor pressure changes during deflating, improving the accuracy and efficiency of the test and reducing testing costs. The device can be installed on four wheels, and by using solenoid valves to control each wheel individually, it can simulate tire blowouts on one, two, three, or even four wheels.

One end of the air chamber is equipped with a wheel bolt sleeve, allowing the air chamber to rotate synchronously with the wheel bolt sleeve, thus ensuring a continuous connection between the air pipes and the tire. The other end of the air chamber is equipped with a pipe connector for connecting to an external air pump or inflation / deflation system with a high gas flow rate. Multiple air pipes are located on the side of the air chamber; the specific number of air pipes depends on the tire size—larger tires require more air pipes—to achieve instantaneous deflation and more realistically simulate a tire blowout. One end of each air pipe has an air inlet connector that connects to the air chamber, and the other end has a quick-connect plug that plugs into the wheel rim. The modular design of the air pipes allows for independent replacement when a single pipe is damaged, reducing maintenance costs.

[0016] The wheel bolt sleeve of this utility model is connected to the disc by fasteners. The disc is provided with multiple waist holes, and the number of waist holes should not be less than six, which is not less than the number of common tire bolts. The length direction of the waist holes all passes through the center of the disc. The radial design of the waist holes allows the fasteners to be adjusted along the radius of the disc to adapt to the installation requirements of wheel bolts of different specifications and enhance versatility. The multiple waist holes are evenly arranged around the circumference of the disc. The evenly distributed waist holes and symmetrical layout can reduce the dynamic imbalance caused by uneven mass distribution of the disc and ensure stability during high-speed rotation.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise expressly indicated by the present invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Currently, tire blowout testing is a crucial step in vehicle safety performance testing, evaluating a vehicle's handling and stability under sudden tire blowout conditions. Existing tire blowout testing devices often cannot precisely control the blowout location, leading to inaccurate test results. Traditional devices directly damage the tire during a blowout, severely impacting testing efficiency and cost. The following detailed description, in conjunction with the accompanying drawings, provides a vehicle active deflation simulation tire blowout device, aiming to overcome the shortcomings of existing technologies. This device can precisely control a single wheel for repeatable active deflation to simulate a tire blowout scenario. The following detailed description, in conjunction with the accompanying drawings, provides a vehicle active deflation simulation tire blowout device.

[0022] Example 1 This embodiment provides a vehicle active deflation device to simulate tire blowout, such as... Figures 1-3As shown, it includes: wheel bolt sleeve 2, air chamber 4, sliding sealing assembly 5, pipe connector 6, and support bracket 9; the wheel bolt sleeve 2, air chamber 4, sliding sealing assembly 5, and pipe connector 6 are arranged in sequence. The wheel bolt sleeve 2 is installed on the wheel and rotates with the wheel. The sliding sealing assembly 5 is provided 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 rotated relative to each other. 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 precisely control the deflation of one or several wheels during vehicle testing, while ensuring that other wheels are not affected. Because the tires are not damaged, they can be re-inflated for repeated tests. The device is also equipped with a pressure sensor to detect the pressure changes of the wheels in real time during the deflation process, which improves the accuracy and efficiency of the test and reduces the test cost. The device can be installed on four wheels, and by using the solenoid valve 8 to control one wheel at a time, it can be arbitrarily combined to achieve simulated tire blowouts of one, two, three, or even four wheels.

[0023] As a further implementation, the air chamber 4 has a cylindrical structure, connecting multiple air pipes 1 and a main pipeline connector 6. One end of the air chamber 4 is equipped with a wheel bolt sleeve 2, allowing the air chamber 4 to rotate synchronously with the wheel bolt sleeve 2, thus creating conditions for continuous connection between the air pipes 1 and the tire. The other end of the air chamber 4 is equipped with a pipeline connector 6 for connecting to an external air pump or inflation / deflation system, which has a high gas flow rate. Multiple air pipes 1 are located on the side of the air chamber 4; in this embodiment, six air pipes 1 are used as an example. The specific number of air pipes 1 depends on the size of the tire; the larger the tire, the more air pipes 1 are needed to achieve instantaneous deflation and more realistically simulate a tire blowout. One end of each air pipe 1 is equipped with an air inlet connector connected to the air chamber 4, and the other end is equipped with a quick-connect plug, which connects to the wheel rim. The modular design of the air pipes 1 supports independent replacement when a single pipe is damaged, reducing maintenance costs.

[0024] As a further implementation, there are multiple wheel bolt sleeves 2, which are respectively arranged and fixedly connected to the nuts of the bolts on the wheel, and are set at one end of the air chamber 4 via a disc 3. The multiple wheel bolt sleeves 2 are evenly arranged around the circumference of the disc 3. One end of each wheel bolt sleeve 2 is detachably provided with a bolt head, and the other end is fixedly connected to the disc 3. The bolt head is connected to the nut of the wheel bolt. By changing the bolt head of different sizes, it is easy to match different wheel bolts, thereby improving the applicability of the device.

[0025] As a further implementation, the wheel bolt sleeve 2 is connected to the disc 3 by fasteners. The disc 3 is provided with a plurality of waist holes 12, and the number of waist holes 12 is not less than six. The length direction of each waist hole 12 passes through the center of the disc 3. The radial design of the waist holes 12 allows the fasteners 11 to be adjusted in position along the radius of the disc 3, adapting to the installation requirements of wheel bolts of different specifications and enhancing versatility. The plurality of waist holes 12 are evenly arranged around the circumference of the disc 3. The evenly distributed waist holes 12 and the symmetrical layout can reduce the dynamic imbalance caused by uneven mass distribution of the disc 3, ensuring stability during high-speed rotation.

[0026] As a further implementation, a pressure sensor 7 is provided on the pipeline connector 6 to monitor the tire pressure changes during the entire test; a solenoid valve 8 is provided at the end of the pipeline connector 6 away from the sliding sealing assembly 5 to control the closing and release of gas in the entire pipeline.

[0027] As a further implementation, the support bracket 9 consists of a vertical rod and a horizontal rod. One end of the vertical rod is fixedly connected to the pipe connector 6, and one end of the horizontal rod is movably mounted on the vertical rod. The other end of the horizontal rod is equipped 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, preventing the pipe connector 6, air passage, and wiring from rotating during the test. The multi-stage adjustment of the vertical rod and horizontal rod, combined with the displacement of the air suction cup 10, can adapt to different pipe diameters and complex curved surface installation environments, solving the problem of single positioning of traditional brackets. The sliding design of the suction cup allows for fine adjustment of the installation position, avoiding installation interference caused by pipe layout offset.

[0028] As a further implementation, both the vertical and horizontal bars are telescopic bars, and locking devices are provided in the vertical and horizontal bars to lock and fix them at any length position, so that the support bracket 9 can adapt to different vehicle models and can attach the air suction cup 10 to 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 and horizontal bars and passes through the vehicle to connect with the solenoid valve 8 switch, so that the operator can control the solenoid valve 8 from inside the vehicle.

[0029] As a further implementation, the air suction cup 10 consists of a fixed bracket and two suction cups. The top of the fixed bracket is movable relative to the crossbar. The two suction cups are arranged side by side at the bottom of the fixed bracket. The air suction cup 10 can be pressed and adsorbed, which improves efficiency by 70% compared with the bolt fixing method. It is especially suitable for maintenance scenarios with frequent disassembly and assembly. The modular structure supports manual operation without additional tools, reducing labor costs.

[0030] The simulation process is as follows: S1. 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. S2. When the vehicle reaches the predetermined state, the solenoid valve 8 is opened by the switch control line, and the air in the tire is released instantly, achieving the effect of a tire blowout. The tire blowout scenario is simulated by releasing air. The test will not damage the tire and can be repeated in a very short time, saving time and material costs. S3. After the test, 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 test simulates a tire blowout by deflating the tire. The test will not damage the tire and can be repeated in a very short time, saving time and material costs and facilitating the next test.

[0031] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
