As shown in fig. 6 to 7, a first comparative example, in which another embodiment of the present invention is: a power storage spring 27 is fixed between the transmission block 22 and the T-shaped plug 23, the power storage spring 27 is in a compressed state in an initial state, an arc-shaped elastic sheet 28 is connected to one end, close to the power storage spring 27, of the outer portion of the T-shaped plug 23 in a sliding mode, and the arc-shaped elastic sheet 28 is fixedly connected with the rim 2; during operation, in the moving process of the transmission block 22, the transmission block can simultaneously push the power storage spring 27 to drive the T-shaped plug 23 to move, the arc-shaped elastic sheet 28 can limit the T-shaped plug 23 in the initial state, and when the T-shaped plug 23 is subjected to overlarge pressure and the force is enough to drive the T-shaped plug 23 to move through the arc-shaped elastic sheet 28, the elastic potential energy of the power storage spring 27 is released, so that the T-shaped plug 23 can drive the colloid in the glue storage tube 24 to be discharged quickly, and the effect of accelerating the discharge of the colloid can be achieved.
The working principle is as follows: when the automobile wheel is used, the tire of an automobile is arranged outside the rim 2, when the automobile wheel normally rubs with the ground, so that the buffer strip 4 cannot influence the normal four-line running of the automobile, when the automobile runs through a pit, if the speed of the automobile is higher right at the moment, the tire of the automobile can deform under larger impact force, so that the rim 2 directly contacts with the pit, at the moment, the buffer strip 4 contacts with the pit before the rim 2, so that the pit needs to firstly collide with the buffer strip 4 and then extrude the buffer air bag 5 to deform the buffer air bag, so that the impact force between the rim 2 and the pit can be buffered, and the wheel is prevented from being broken after rolling and falling into the pit;
in the normal running process of the automobile, the counterweight ball 6 in the buffering airbag 5 can pull the buffering airbag 5 to deform through the elastic sheet 7 in a reciprocating manner under the action of inertia force, in the deformation process of the buffering airbag 5, external air can be sucked into the buffering airbag 5 through the ventilation pipe 8 until the air pressure in the buffering airbag 5 reaches a certain value, and the air cannot be sucked, so that the air pressure in the buffering airbag 5 can be enhanced when the automobile runs to a bumpy road section, the buffering strip 4 is more protruded, and the protection operation is convenient to perform, it needs to be noted that a plurality of pores are formed in the outer part of the buffering airbag 5, the pore diameter of each pore is far smaller than that of the ventilation pipe 8, so that the air in the buffering airbag 5 can be gradually released after the automobile stops moving, and the buffering airbag 5 is prevented from being in an expanded state all the time; the elastic strip 9 can further buffer the buffer strip 4 when the buffer strip is contacted with a pit, so that the rim 2 is protected from being directly broken; the arrangement of the protective net 10 can effectively prevent the blockage of the protective net 10 caused by external garbage in the driving process of an automobile, and in the driving process of the automobile, along with the change of the speed of the automobile, the centrifugal force applied to the cleaning block 11 also changes, so that when the speed of the automobile is higher, the cleaning block 11 can stretch the centrifugal spring 12 to enable the centrifugal spring 12 to deform and slide, and the protective net 10 can be cleaned in the process to prevent the blockage;
after the automobile falls into the pit, the buffer strip 4 is contacted with the pit, once the automobile speed is very fast at the moment, the buffer strip 4 can compress the buffer air bag 5 under a large impact force to break the buffer air bag and drive the counterweight ball 6 to extrude the dividing membrane 14, in the process, the separation membrane 14 can be punctured by the puncture needle head 13 outside the counterweight ball 6, so that the clear water 15 is contacted with the effervescent tablet 16, a large amount of gas can be generated after the clear water 15 is contacted with the effervescent tablet 16, and the buffer strip 4 is ejected out, so that the rim 2 can be buffered by the generated large amount of gas when the automobile runs through the pit at the very fast speed, and the rupture of the rim is prevented; after a large amount of gas is generated, excessive gas enters the detection groove to extrude the detection block 18, the detection block 18 stretches the tension spring 17 after being extruded to deform the tension spring and then pushes the plug contact 19 to be contacted with the emergency stop contact 20, and at the moment, a brake system of the automobile can obtain a signal to start to operate active braking to remind a driver to reduce the speed in time and stop to check wheels; in the process of movement of the detection block 18, the detection block can simultaneously drive the steering push block 21 to move, the steering push block 21 moves to be in contact with the transmission block 22 and can push the transmission block 22 to transversely slide, the transmission block 22 slides to drive the T-shaped plug 23 to move, the T-shaped plug 23 can extrude glue in the glue storage tube 24 after moving, the extruded glue drops on the surfaces of the rim 2 and the spoke 3, so that the surfaces of the rim 2 and the spoke 3 are bonded, and the strength of the rim 2 and the spoke 3 is further improved to prevent breakage; the arrangement of the closing plug 25 can prevent the glue solution in the glue storage tube 24 from volatilizing and deteriorating, and it should be noted that the pressure of the glue solution in the glue storage tube 24 is greater than the clamping force of the closing plug 25 and the glue discharge tube after the T-shaped plug 23 slides; in the running process of the automobile, the stirring balls 26 in the rubber storage tube 24 can stir the colloid in the rubber storage tube 24 under the action of inertia force, the temperature of the rim 2 can also rise to a certain extent in the running process of the automobile, and the rising temperature enables the colloid in the rubber storage tube 24 to keep a flowing state, so that the colloid can be ensured to flow out smoothly;
in the moving process of the transmission block 22, the transmission block can simultaneously push the power storage spring 27 to drive the T-shaped plug 23 to move, the arc-shaped elastic sheet 28 can limit the T-shaped plug 23 in the initial state, and when the T-shaped plug 23 is subjected to overlarge pressure and the force is enough to drive the T-shaped plug 23 to move through the arc-shaped elastic sheet 28, the elastic potential energy of the power storage spring 27 is released, so that the T-shaped plug 23 can drive the colloid in the colloid storage tube 24 to be discharged quickly, and the effect of accelerating the discharge of the colloid can be achieved.
