Description

Technical Field

[0001] This utility model relates to the field of tire blowout device technology, and in particular to a tire blowout device for automobile testing. Background Technology

[0002] Vehicle inspection is an examination to determine the technical condition or working capability of a vehicle. During use, as the time goes by, the parts of a vehicle gradually wear, corrode, deform, and age, and the lubricating oil deteriorates, causing the clearance between mating parts to increase. This leads to looseness in movement, vibration, noise, and leaks of air, water, and oil, resulting in a decline in the vehicle's technical performance. The core of vehicle maintenance is to maintain the vehicle's good technical condition. Vehicles usually undergo tire blowout testing when they leave the factory. Tire blowout testing is mainly to evaluate the sudden change in the vehicle's condition after a tire blowout under different road conditions, different types of tires, and different speeds, and to provide a comprehensive evaluation of the vehicle's handling stability.

[0003] There is currently no corresponding device to handle tire blowouts, making blowouts inconvenient and making it difficult to control the timing of the blowout, which affects subsequent inspections. Utility Model Content

[0004] To address the current technical problem that there is no corresponding device to handle tire blowouts in existing vehicles, which makes tire blowouts inconvenient and makes it difficult to control the timing of the blowout, thus affecting subsequent inspections, this utility model provides a tire blowout inspection device for vehicles.

[0005] This utility model is achieved using the following technical solution: a tire blowout testing device for automobiles, comprising a testing platform, a pair of opposing or moving support frames on the top of the testing platform, a turntable rotatably connected to the inner sides of the pair of support frames, a clamping assembly for fixing the tire on the inner sides of the opposing turntables, a fixing platform fixedly connected to the middle of the top of the testing platform, a tire placed on the top of the fixing platform, and an installation groove provided on the top of the fixing platform, with a blade slidably connected in the installation groove.

[0006] Through the above technical solution, the clamping assembly clamps and fixes the tire, and then the rotatable turntable drives the tire to rotate and move downward with the support frame to approach the blade on the fixed platform, thereby simulating the accidental tire burst during vehicle operation, further improving the realism of the simulation and enhancing the authenticity and reliability of various test data.

[0007] As a further improvement to the above solution, the clamping assembly includes a connecting tube fixed to the inner side of a pair of turntables, one end of which is fixed to a connecting post, the connecting post being slidable inside the connecting tube, and the connecting tube being slidable inside the wheel hub on the tire, and a first servo motor coaxially connected to the turntable is fixed to the outer side of one of the support frames.

[0008] Through the above technical solution, the connecting pipe and connecting column can fix a pair of turntables on both sides of the tire, forming a whole. At this time, the first servo motor is turned on to drive one of the turntables to rotate, so that the pair of turntables and the tire rotate synchronously, and the rotation speed of the tire can be adjusted by the first servo motor.

[0009] As a further improvement to the above solution, a groove is provided at the top of the testing platform, and a bidirectional reciprocating screw is rotatably connected inside the groove. A second servo motor coaxial with the bidirectional reciprocating screw is fixedly connected to one of the vertically parallel outer sides of the testing platform. A moving block is connected to the outer nut pair of the bidirectional reciprocating screw, and the support frame is fixedly connected to the top of the moving block.

[0010] Through the above technical solution, the second servo motor drives the bidirectional reciprocating screw inside the groove to rotate, causing a pair of moving blocks to move towards each other or away from each other, thereby realizing the fixing and release of the tire by a pair of support frames.

[0011] As a further improvement to the above solution, the support frame is divided into a first support column and a second support column, the second support column slides inside the first support column, and a hydraulic cylinder is fixedly connected between the first support column and the second support column.

[0012] The above technical solution allows the hydraulic cylinder to be flexibly adjusted up and down for the second support column.

[0013] As a further improvement to the above solution, openings are provided on both sides of the fixed platform. A telescopic spring and a telescopic column are fixedly connected to the bottom of the opening. The telescopic column is located inside the telescopic spring, and a limit plate is fixedly connected to the outer end of the telescopic column and the telescopic spring.

[0014] Through the above technical solution, the telescopic spring and telescopic column can enable the limiting plate to adaptively clamp tires of different widths.

[0015] As a further improvement to the above solution, an inclined plate is fixedly connected to one of the outer sides of the testing platform in a horizontal parallel manner.

[0016] The above technical solution makes it easier for workers to roll tires onto the fixed platform.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a second servo motor to drive a pair of support frames to move in opposite directions, thus fixing the tire in place with the clamping assembly. The first servo motor is then activated to rotate the turntable, simulating the tire's driving state. Combined with a hydraulic cylinder, when the tire is burst by a blade, the blade penetrates the tire's interior and slides out of the mounting groove, simulating an accidental tire burst during vehicle operation. This further enhances the realism of the simulation and improves the authenticity and reliability of various test data. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please combine Figures 1-5This embodiment of a tire blowout testing device for automobiles includes a testing platform 1. A pair of support frames 2 that move towards or away from each other are provided on the top of the testing platform 1. Turntables 3 are rotatably connected to the inner sides of the pair of support frames 2. Clamping components for fixing tires 5 are provided on the inner sides of the turntables 3. A fixing platform 4 is fixedly connected to the middle of the top of the testing platform 1. Tires 5 are placed on the top of the fixing platform 4, and an installation groove 6 is provided on the top of the fixing platform 4. A blade 7 is slidably connected in the installation groove 6.

[0028] The clamping assembly clamps and fixes the tire 5, and then the rotatable turntable 3 drives the tire 5 to rotate, and it moves downward with the support frame 2 towards the blade 7 on the fixed platform 4, simulating an accidental tire blowout during vehicle operation. This further improves the realism of the simulation and enhances the authenticity and reliability of various test data.

[0029] Combination Figure 1 and Figure 2 The clamping assembly includes a connecting tube 8 fixed to the inner side of a pair of turntables 3, with a connecting post 9 fixed to the end of one of the connecting tubes 8. The connecting post 9 is slidable inside the connecting tube 8, and the connecting tube 8 is slidable inside the hub of the tire 5. A first servo motor 10 coaxially connected to the turntable 3 is fixed to the outer side of one of the support frames 2.

[0030] When a pair of support frames 2 move toward each other, the connecting pipes 8 located on the inner side of a pair of turntables 3 will move synchronously toward both sides of the wheel hub on the tire 5. At this time, the connecting post 9 on one of the turntables 3 will first enter the interior of the wheel hub, and then slide into the connecting pipe 8 on the other turntable 3 inside the wheel hub, until the connecting pipes 8 on the two turntables 3 are in contact.

[0031] Combination Figure 1 The top of the testing table 1 has a groove 11, and a bidirectional reciprocating screw 12 is rotatably connected inside the groove 11. A second servo motor 13, coaxial with the bidirectional reciprocating screw 12, is fixedly connected to one of the vertical parallel outer sides of the testing table 1. A moving block 14 is connected to the outer nut pair of the bidirectional reciprocating screw 12, and the support frame 2 is fixedly connected to the top of the moving block 14.

[0032] The second servo motor 13 drives the bidirectional reciprocating screw inside the groove 11 to rotate, causing a pair of moving blocks 14 to move towards or away from each other, thereby fixing and releasing the tires 5 of the pair of support frames 2.

[0033] Combination Figure 3 The support frame 2 is divided into a first support column 201 and a second support column 202. The second support column 202 slides inside the first support column 201, and a hydraulic cylinder 15 is fixedly connected between the first support column 201 and the second support column 202.

[0034] The hydraulic rod installed between the first support column 201 and the second support column 202 can drive the second support column 202 to move up and down and slide inside the first support column 201.

[0035] Combination Figure 4 Both sides of the fixed platform 4 are provided with openings 16. A telescopic spring 17 and a telescopic column 18 are fixedly connected to the bottom of the opening 16. The telescopic column 18 is located inside the telescopic spring 17, and the outer ends of the telescopic column 18 and the telescopic spring 17 are fixedly connected with limit plates 19.

[0036] When the tire 5 rolls up from the side of the fixed platform 4, the tire 5 will first come into contact with the inside of a pair of limiting plates 19. If the width of the tire 5 is greater than the distance between the pair of limiting plates 19, the tire 5 will squeeze the pair of limiting plates 19 to move outward. The movement of the limiting plates 19 will simultaneously drive the telescopic column 18 and the telescopic spring 17 inside the mounting hole to extend, so that the pair of limiting plates 19 can limit and clamp tires 5 of different widths.

[0037] The implementation principle of a tire blowout detection device for automobiles in this application embodiment is as follows:

[0038] Before testing, the tire 5 is rolled from the test bench 1, which is horizontally parallel to the inclined plate 20 fixed on the outer side, onto the fixed platform 4.

[0039] When the tire 5 rolls up from the side of the fixed platform 4, the tire 5 will first come into contact with the inside of a pair of limiting plates 19. If the width of the tire 5 is greater than the distance between the pair of limiting plates 19, the tire 5 will squeeze the pair of limiting plates 19 to move outward. The movement of the limiting plates 19 will simultaneously drive the telescopic column 18 and telescopic spring 17 inside the mounting hole to extend, so that the pair of limiting plates 19 can limit and clamp the tires 5 of different widths and prevent them from shifting. Because the top center of the fixed platform 4 is arc-shaped, when the tire 5 is located inside the arc at the top of the fixed platform 4, it will break free from the clamping of the pair of limiting plates 19 and remain upright.

[0040] At this time, the second servo motor 13 is activated;

[0041] When the second servo motor 13 is activated, the bidirectional reciprocating screw inside the groove 11 at the top of the detection platform 1 rotates, causing a pair of moving blocks 14 to move towards each other. This, in turn, drives the support frame 2 at the top of the moving blocks 14 to move towards each other, causing the turntable 3 inside the support frame 2 to move synchronously. At this time, the connecting pipes 8 located inside the pair of turntables 3 will move synchronously towards both sides of the wheel hub on the tire 5. The connecting post 9 on one of the turntables 3 will first enter the interior of the wheel hub, and then slide into the connecting pipe 8 on the other turntable 3 inside the wheel hub, until the connecting pipes 8 on the two turntables 3 are in contact.

[0042] Then, the hydraulic cylinder 15 is activated to move upward. At this time, the second support column 202 slides upward inside the first support column 201, so that the tire 5 is released from the clamping of a pair of limit plates 19. Then, the first servo motor 10 is activated to drive one of the turntables 3 to rotate, thereby driving the tire 5 to rotate counterclockwise, so as to realize the state of simulating driving.

[0043] At this time, the blade 7 is slidably installed inside the mounting slot 6 opened at the top of the fixed platform 4. The counterclockwise rotating tire 5 will follow the descent of the hydraulic cylinder 15 and come into contact with the blade 7. At this time, after the tire 5 is burst by the blade 7, the blade 7 will pierce into the tire 5 and slide out of the mounting slot 6, thereby simulating the accidental bursting of the tire 5 during vehicle operation.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
