Description

Technical Field

[0001] The utility model relates to the technical field of vehicle simulation tooling, in particular to a vehicle tire blowout training device and a training vehicle. Background Art

[0002] A tire blowout is an unexpected situation that may occur during driving. If the driver handles it improperly, it may cause an accident. The main reason for the driver's improper handling is that tire blowouts occur less frequently and the driver lacks experience in dealing with them. After sufficient practice, the driver will be better able to deal with tire blowouts.

[0003] The existing practice method is mainly to lay puncture spikes or detonators on the route of the vehicle. When the wheel rolls over the puncture spikes or detonators, the tire will leak air quickly due to being punctured, or the detonator will explode a hole and leak air quickly, simulating the situation of a tire blowout. The driver can practice how to deal with it at this time. After completing the practice, you need to replace the new tire and then proceed to the next round of practice.

[0004] The defects of this practice method include: each practice requires a puncture or explosion of a tire, which is costly; each practice requires the vehicle to stop and replace a new tire before the next practice, which takes a long time to prepare the vehicle and reduces the practice efficiency.

[0034] The present embodiment discloses a training vehicle, which can be used for, but not limited to, tire blowout training. Specifically, the training vehicle includes a vehicle body and a vehicle tire blowout training device connected to each other. Figures 1 to 3 As shown, the vehicle tire blowout training device includes a tire assembly 1, an exhaust assembly, an air-inflating assembly and a control device (not shown). The exhaust assembly and the air-inflating assembly are respectively connected to the tire assembly 1, and the control device is respectively connected to the exhaust assembly and the air-inflating assembly. The specific structure of the tire assembly 1 is not limited. In this embodiment, a vacuum tire is used as the tire assembly 1. The exhaust assembly and the air-inflating assembly can be more closely connected to the tire assembly 1, and the exhaust and air-inflating are smoother and more stable. Of course, the tire assembly 1 composed of an inner tube and an outer tube in the existing structure can also be used. It is only necessary to make adaptive changes to the connection structure between the exhaust assembly and the inner tube, and the connection structure between the air-inflating assembly and the inner tube. There are few changes to the existing structure and a wide range of applications.

[0035] The control device is used to start and stop the exhaust assembly and the air filling assembly. When the exhaust assembly is in the open state, the air in the tire assembly 1 can be discharged until the air pressure in the tire assembly 1 reaches the tire pressure value after a tire burst (which may be but is not limited to 0.5 atmospheres); when the air filling assembly is in the open state, air can be filled into the tire assembly 1 until the air pressure in the tire assembly 1 reaches the set tire pressure value for normal operation of the vehicle (which may be but is not limited to 8 atmospheres). Among them, when the tire pressure value is 0.5 atmospheres, it can ensure that the tire assembly 1 will not fall off the bead, and when the air pressure is lower, it may fall off the bead.

[0036] In this embodiment, the control device can be a centralized or distributed controller. For example, the controller can be a single single-chip microcomputer or a distributed plurality of single-chip microcomputers. The control program can be run in the single-chip microcomputer to control the start and stop of the exhaust component and the air supply component to realize their functions.

[0037] The exhaust component of the vehicle tire blowout training device can quickly exhaust the air in the tire component 1, simulating the situation that the tire is quickly deflated after a tire blowout, and the driver can practice how to reasonably deal with the tire blowout danger. After the practice is completed, the tire component 1 is quickly inflated to the working air pressure through the air filling component, and the next tire blowout simulation practice can be started at this time, which has high training efficiency; there is no need to damage the tire, which reduces the cost required for practice and makes vehicle driving safer; there is no need to change the tire between two practices, which saves time and effort.

[0038] The specific structure of the exhaust assembly is not limited, as long as it can quickly exhaust the air in the tire assembly 1. Figure 1 , Figure 3 and Figure 4 As shown, the exhaust assembly includes an exhaust switch valve 21, and an airway structure with two ends opened is formed in the exhaust switch valve 21. One end of the exhaust switch valve 21 is connected to the tire assembly 1, and the other end is connected to the atmosphere. Specifically, when the exhaust switch valve 21 is in an open state, the tire assembly 1 is connected to the atmosphere through the exhaust switch valve 21, and the high-pressure air in the tire assembly 1 is quickly discharged into the atmosphere through the exhaust switch valve 21, which is very similar to the state of the tire being instantly deflated when a tire blows out, and the simulation effect is good.

[0039] The specific method of controlling the exhaust switch valve 21 to open or close is not limited. In one structure, the exhaust switch valve 21 is connected to a control device, and the control device controls the opening or closing of the exhaust switch valve 21 through electrical signals, etc. The number of components required is small, and the control is simple and convenient.

[0040] In another structure, the exhaust assembly further includes an exhaust control valve 22 and a control air nozzle 23, the exhaust switch valve 21 is a pneumatic valve, and the exhaust control valve 22 is connected to the exhaust switch valve 21 through the control air nozzle 23. The control device can control the exhaust control valve 22 to supply air to the exhaust switch valve 21. When the air supply reaches a certain amount or a certain air pressure, the exhaust switch valve 21 starts, and when the exhaust control valve 22 stops supplying air, the exhaust switch valve 21 is closed. Pneumatic valve products are mature and have fast response speed, and the control method is reliable.

[0041] The specific setting positions of the exhaust switch valve 21 and the control air nozzle 23 are not limited. In this embodiment, the vehicle tire blowout training device also includes a wheel hub 4, the exhaust switch valve 21 and the control air nozzle 23 are respectively arranged on the wheel hub 4, the tire assembly 1 is sleeved on the outer periphery of the wheel hub 4, and the exhaust switch valve 21 is arranged in the space enclosed by the tire assembly 1 and the wheel hub 4.

[0042] The wheel hub 4 is provided with an exhaust hole (not shown), and the other end of the exhaust switch valve 21 is welded to the exhaust hole, and the exhaust switch valve 21 is connected to the atmosphere through the exhaust hole. When the exhaust switch valve 21 is closed, the exhaust hole and the inside of the tire assembly 1 are separated by the exhaust switch valve 21, and the high-pressure air in the tire assembly 1 will not be discharged into the atmosphere; when the exhaust switch valve 21 is opened, the exhaust hole is connected to the inside of the tire assembly 1, and the high-pressure air in the tire assembly 1 is discharged into the atmosphere through the airway structure in the exhaust switch valve 21 and the exhaust hole on the wheel hub 4, and the exhaust speed is fast.

[0043] The specific number of the exhaust switch valve 21 and the control air nozzle 23 is not limited. In this embodiment, two exhaust switch valves 21 and two control air nozzles 23 are respectively provided on the wheel hub 4, and the exhaust efficiency is high; the exhaust switch valve 21 and the control air nozzle 23 correspond one to one, and the control of the exhaust switch valve 21 is more stable, and the exhaust switch valve 21 responds more promptly. The two exhaust switch valves 21 are symmetrically arranged relative to the center of the wheel hub 4, and can exhaust at two points far apart on the tire assembly 1 at the same time, and the exhaust speed is fast.

[0044] The specific structure of the air-inflation component is not limited, as long as it can quickly inflate the tire assembly 1. Figure 1 , Figures 3 to 5 As shown, the air supply assembly includes an air circuit on-off control valve 31 and at least one air inlet nozzle 33, and the air circuit on-off control valve 31 is connected to the tire assembly 1 through the air inlet nozzle 33. Specifically, the air circuit on-off control valve 31 is a normally open valve, and the outlet end of the air circuit on-off control valve 31 is connected to the air inlet nozzle 33 through an air pipe, and gas can be filled into the tire assembly 1 through the air circuit on-off control valve 31 and the air inlet nozzle 33.

[0045] One end of the air inlet nozzle 33 is connected to the tire assembly 1, and the other end is connected to the air circuit on-off control valve 31. After the control device opens the air circuit on-off control valve 31, air is filled into the tire assembly 1 through the air circuit on-off control valve 31 and the air inlet nozzle 33. The air pressure measuring device continuously detects the air pressure in the tire assembly 1 and sends the detection result to the control device. When the air pressure in the tire assembly 1 reaches the set tire pressure value, the control device closes the air circuit on-off control valve 31 and stops filling the tire assembly 1.

[0046] The specific structure of the gas circuit on-off control valve 31 is not limited, as long as it can control the opening and closing of the air inlet nozzle 33. In the present embodiment, the air supply component also includes a gas circuit closing valve 32, and the gas circuit closing valve 32 is respectively connected to the control device and the gas circuit on-off control valve 31. The gas circuit on-off control valve 31 is a pneumatic valve, and the gas circuit closing valve 32 is a normally closed valve. When the control device supplies power to the gas circuit closing valve 32, the gas circuit closing valve 32 opens, and the gas circuit closing valve 32 can deliver gas to the gas circuit on-off control valve 31, thereby closing the gas circuit on-off control valve 31 (ending the normally open state); after the gas circuit closing valve 32 stops delivering gas, the gas circuit on-off control valve 31 opens (restoring the normally open state). The gas circuit closing valve 32 is a solenoid valve, which has many product types, stable functions, low cost, and is easy to use.

[0047] The specific setting positions of the air circuit on-off control valve 31, the air circuit closing valve 32 and the exhaust control valve 22 are not limited. In this embodiment, the vehicle tire blowout training device also includes a wheel end bottom cover 5, and the air circuit on-off control valve 31, the air circuit closing valve 32 and the exhaust control valve 22 are all arranged on the wheel end bottom cover 5, and the installation is stable. During the driving of the training vehicle, the air circuit on-off control valve 31, the air circuit closing valve 32 and the exhaust control valve 22 are not easy to fall off, and the use is safer.

[0048] Based on the above structure, Figure 1 , Figure 3 and Figure 6 As shown, the vehicle tire burst training device further includes a rotating electrical slip ring 6 and a wheel end upper cover 7, and a pressure gauge is provided on the wheel end upper cover 7. The rotating electrical slip ring 6 includes a rotating portion 61 and a fixed portion 62, and the rotating portion 61 can rotate around the fixed portion 62. The fixed portion 62 is provided with an air supply nozzle 63, and the air supply nozzle 63 is connected to an on-board air supply device (not shown), and the air supply device can provide air to the vehicle tire burst training device through the air supply nozzle 63.

[0049] The specific method for air to reach the tire assembly 1 from the air supply nozzle 63 is not limited, and any technical solution that can achieve this result in the prior art can be used. In this embodiment, a multi-way valve (preferably a four-way valve) is provided on the wheel end bottom cover 5, one outlet end of the multi-way valve is connected to the air circuit on-off control valve 31, another outlet end is connected to the exhaust control valve 22, and another outlet end is connected to the air circuit closing valve 32. The air outlet end of the air supply nozzle 63 is connected to the multi-way valve, and the multi-way valve is connected to the air inlet nozzle 33 through the air circuit on-off control valve 31, and then connected to the tire assembly 1 through the air inlet nozzle 33.

[0050] The exhaust control valve 22 and the gas circuit closing valve 32 are both normally closed valves, and the gas circuit on-off control valve 31 is a normally open valve. When the high-pressure gas reaches the multi-way valve through the gas supply nozzle 63, it can be directly filled into the tire assembly 1 through the gas circuit on-off control valve 31 and the air inlet nozzle 33 to achieve air replenishment of the tire assembly 1.

[0051] When it is necessary to simulate a tire blowout, power is supplied to the exhaust control valve 22 and the air circuit closing valve 32, and the exhaust control valve 22 and the air circuit closing valve 32 are started. The outlet end of the exhaust control valve 22 is connected to the exhaust switch valve 21 through the air pipe and the control air nozzle 23. After the high-pressure gas passes through the exhaust control valve 22, the air pipe and the control air nozzle 23, the exhaust switch valve 21 is controlled to open, and the tire assembly 1 begins to exhaust. The outlet end of the air circuit closing valve 32 is connected to the air circuit on-off control valve 31 through the air pipe. The high-pressure gas controls the air circuit on-off control valve 31 to close through the air circuit closing valve 32 and the air pipe, and the air inlet nozzle 33 stops inflating the tire assembly 1.

[0052] After the training is completed, the exhaust control valve 22 and the gas circuit closing valve 32 are powered off, and the exhaust control valve 22 and the gas circuit closing valve 32 are restored to the closed state. The exhaust switch valve 21 is closed, and the gas in the tire assembly 1 stops being discharged to the outside; the gas circuit on-off control valve 31 is restored to the open state, and the high-pressure gas is filled into the tire assembly 1 through the gas circuit on-off control valve 31 and the air inlet nozzle 33, so as to achieve the air replenishment of the tire assembly 1.

[0053] The rotating electrical slip ring 6 is arranged at the center of the wheel end upper cover 7, the rotating part 61 is connected to the wheel end upper cover 7, and the wheel end upper cover 7 is directly or indirectly connected to the tire assembly 1. The wheel end upper cover 7 can rotate synchronously with the tire assembly 1, and the rotating part 61 rotates synchronously with the wheel end upper cover 7, but the fixed part 62 always remains non-rotating, ensuring that the air path between the air supply nozzle 63 and the air supply device will not be twisted or even knotted due to the rotation of the tire assembly 1, and the air supply is more stable and smooth.

[0054] In this embodiment, the air circuit on-off control valve 31 is arranged on the wheel end bottom cover 5, and the air inlet nozzle 33 is arranged on the wheel hub 4. The wheel end bottom cover 5 and the wheel hub 4 can rotate synchronously with the tire assembly 1, and the air circuit on-off control valve 31 rotates synchronously with the wheel end bottom cover 5, and the air inlet nozzle 33 rotates synchronously with the wheel hub 4. The specific method between the non-rotating air supply nozzle 63 and the rotating air circuit on-off control valve 31 is not limited, and any structure that can achieve stable connection between the two in the prior art can be used.

[0055] In this embodiment, the air circuit on-off control valve 31 is in a strip shape, one end of which is arranged at the center of the wheel end bottom cover 5 and the other end is located near the edge of the wheel end bottom cover 5. When the wheel end bottom cover 5 rotates, the center of the wheel end bottom cover 5 only rotates around itself and does not move up and down. One end of the air circuit on-off control valve 31 only needs to be rotatably connected to the air supply nozzle 63 and a sealing device such as a sealing ring is provided at the connection. The other end of the air circuit on-off control valve 31 is directly connected to the air intake nozzle 33. The wheel end bottom cover 5 and the wheel hub 4 rotate synchronously, so the air circuit on-off control valve 31 and the air intake nozzle 33 can always be in a stable connection state during the driving of the training vehicle.

[0056] The specific connection structure between the wheel end cover 7 and the tire assembly 1 is not limited. In this embodiment, the vehicle tire blowout training device also includes a wheel end shell 8 and a tire tread cover 9. The wheel end cover 7 is connected to the tire tread cover 9 through the wheel end shell 8 and the wheel end bottom cover 5, and then the overall structure is connected to the tire assembly 1 through the wheel hub 4. The structure is simple and reasonable, and the connection state is stable.

[0057] In order to better simulate the tire blowout state, the vehicle tire blowout training device also includes a sound simulation device connected to the control device. The sound simulation device can emit a huge explosion sound effect, which, combined with the rapid exhaust of the tire assembly 1, can more realistically simulate the tire blowout state, and the training effect is good.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
