Technical Field
The invention relates to the technical field of automobile tires, in particular to an automobile emergency reaction inner tube.
Background
The vacuum tire is a pneumatic tire without an inner tube, also called a low-pressure tire or a pneumatic tire, and has high elasticity and wear resistance, good adhesive force and heat dissipation performance.
In order to avoid rapid air leakage after the vacuum tire is punctured, automatic tire repair liquid is usually filled in the vacuum tire, and the automatic tire repair liquid is solidified at a leak hole quickly when meeting air solidification, so that the leak hole is automatically blocked.
In the above case, although the leak is small, the automatic tire repair liquid is not useful even when a tire burst occurs or the leak is large, and the large leak cannot be repaired. In this situation, the vacuum tire can be quickly deflated, the tire pressure is insufficient, the automobile cannot continue to run, and the tire can be replaced or rescued in situ. However, the tire burst is often unpredictable, and if the tire burst occurs on an expressway or a road section with traffic jam, the vehicle is stopped in the middle of the road. The rear-end collision is very easy to happen on the expressway, and serious traffic accidents are caused; when the road is in a traffic jam road section, the traffic jam and even paralysis are caused.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides an automobile emergency reaction inner tube, which is used for overcoming the defect that a vacuum tube cannot be continuously used after being burst, and reducing the possibility of traffic accidents.
The invention provides an automobile emergency reaction inner tube, which comprises a tube body, a triggering mechanism and an inflating mechanism, wherein the triggering mechanism is arranged on the tube body; the tire body, the triggering mechanism and the inflating mechanism are all arranged inside the vacuum tire, and the tire body is sleeved on the outer surface of the hub and the inflating port of the inflating mechanism is communicated with the tire body;
the triggering mechanism comprises a telescopic rod, the pressing end of the telescopic rod faces the vacuum tire along the radial direction, and the pressing end extends out of the maximum profile edge of the wheel hub, and the triggering end of the telescopic rod triggers the inflating mechanism and enables the tire body to be inflated and filled in the vacuum tire by squeezing the telescopic rod.
The invention has the beneficial effects that:
when the vacuum tire is punctured or the tire is burst and cannot be filled and repaired through the automatic tire repair liquid, the tire pressure of the vacuum tire is rapidly reduced, and the hub is contacted with the ground after the vacuum tire is shriveled. Because the pressing end of the telescopic rod extends out of the maximum outline edge of the hub, the pressing end is contacted with the ground while the hub is contacted with the ground. The telescopic rod is retracted after being extruded, the other end (namely the triggering end) of the telescopic rod triggers the inflating mechanism, the inflating mechanism instantly generates gas and inflates the tire body, and the tire body is inflated to be filled in the vacuum tire, so that a quick spare tire is formed. The spare tire can support a vehicle to continuously run for a distance enough to support the vehicle to run to a safe area, so that the defect that the vacuum tire cannot be continuously used after being burst is overcome, and the possibility of traffic accidents is reduced.
Preferably, the trigger mechanism further comprises a fixed cylinder sleeved outside the telescopic rod, and a spring is arranged inside the fixed cylinder and used for extending the pressing end of the telescopic rod out of the fixed cylinder.
The telescopic rod is fixedly connected with a fixed disc, a ring body is arranged in the fixed cylinder, and the telescopic rod penetrates through the ring body. And the spring is compressed between the fixed disc and the annular body, so that the pressing end of the telescopic rod is ejected out of the fixed cylinder through the spring.
Preferably, the carcass is provided with a plurality of through holes along the radial direction, and the through holes are distributed at equal intervals along the circumferential direction.
Preferably, one of the fixed cylinders is fixed in each through hole, so that all the fixed cylinders are radially distributed around the hub.
Twelve fixed cylinders and telescopic rods are arranged in total, and as long as one telescopic rod is compressed, the triggering mechanism can be triggered, so that the inflating mechanism instantly generates gas and inflates the gas into a tire body.
Preferably, the inflation mechanism comprises an annular outer shell, a combustion cylinder, a trigger and a power supply, wherein the combustion cylinder, the trigger and the power supply are arranged inside the outer shell, the outer shell is positioned between the tire body and the hub, and the tire body is fixed on the outer surface of the outer shell;
the first combustion cavity of the combustion cylinder is communicated with the inner cavity of the tire body, and the side wall of the combustion cylinder protrudes outwards to form a second combustion cavity; the trigger is fixedly connected with the bulge, and the ignition end of the trigger extends into the second combustion chamber; the trigger is electrically connected with a power supply.
During installation of the apparatus, the first combustion chamber is filled with a gas generating agent and the second combustion chamber is filled with a pilot agent. When the inflating mechanism is triggered by the trigger mechanism, the trigger heats the igniting agent in the second combustion chamber, the igniting agent then ignites the gas generating agent, the gas generating agent generates a certain amount of gas after combustion, and the gas is filled in the inner chamber of the tire body to complete automatic and rapid inflation.
Preferably, the trigger mechanism further comprises a contact switch installed in the housing, the contact switch comprises a mounting seat, a first elastic sheet and a second elastic sheet, the mounting seat is fixed in the housing, the first elastic sheet and the second elastic sheet are both fixed on the mounting seat, and the contact portion of the first elastic sheet is located right above the contact portion of the second elastic sheet.
Preferably, one contact switch is arranged right below each through hole, and the triggering ends of all the telescopic rods penetrate through the shell and are opposite to the first elastic sheets of the corresponding contact switches; all the contact switches are connected in parallel and then connected in series with the trigger and the power supply.
The telescopic link is by the withdrawal in the fixed cylinder after the extrusion, and the trigger end will extrude first shell fragment and contact with the second shell fragment to make the trigger switch on the power. The design of the triggering mechanism is simple and effective, the telescopic rods and the contact switches form one-to-one correspondence, only one contact switch is conducted to trigger the inflating mechanism, the smooth activation of the device under the condition of tire burst is ensured, and the safety performance is improved.
Preferably, two combustion cylinders and two triggers are arranged in the shell, wherein one combustion cylinder and one trigger are positioned on one side of the shell, and the other combustion cylinder and the other trigger are positioned on the other side of the shell; all the contact switches are connected in parallel and then connected in series with two triggers and a power supply.
The two combustion cylinders and the trigger can realize inflation of the tire body more quickly, inflation efficiency is improved, and maintenance time is further shortened.
