when flexible expansion spare 2 is oppressed by the car spare tyre of being fixed in the install bin 1, first body of rod 603 removes for gas box 601 rotates and drives balancing weight 604 and move, through balancing weight 604, so that flexible expansion spare 2 vibration connection in the outer fringe lateral wall of car spare tyre.
In some actual conditions vehicle can jolt in the driving process, make the spare tyre also can jolt and remove in the driving process, can oppress flexible inflation spare part 2 when the spare tyre diameter increases at first, the inside partial inflation medium of inflation air chamber 3 discharges this moment, and flexible inflation spare part 2 can extrude first body of rod 603, because first body of rod 603 and air box 601 threaded connection, then can make air box 601 rotate, it is rotatory to make air box 601 drive balancing weight 604, because balancing weight 604 counter weight is uneven, then can make it vibrate, and then drive the outer wall vibrations of flexible inflation spare part 2, make it be the vibrations contact in the contact with the tire, prevent to openly contact all the time and damage in the friction.
Further, the protection assembly 6 further includes a second sealing member 602 disposed in the air box 601, the second sealing member 602 is connected to an end of the first rod 603 away from the flexible expansion member 2;
wherein, the gas box 601 is provided with an opening for transmitting the expansion medium, and the opening is provided with a gas regulating component 605;
the gas regulating assembly 605 serves to limit the speed at which the inflation medium outside the gas box 601 is transferred into the gas box 601, while the second seal 602 discharges the inflation medium inside the gas box 601 through the opening by the movement of the first rod 603.
Specifically, the gas regulating assembly 605 includes a sliding rod 6051 slidably connected to the gas box 601, an exhaust cylinder 6052 disposed on the sliding rod 6051, and a first exhaust hole 6053 and a plurality of second exhaust holes 6054 disposed on the exhaust cylinder 6052;
the first exhaust hole 6053 is provided in an end portion of the exhaust cylinder 6052 remote from the slide bar 6051, the second exhaust hole 6054 is provided in a side wall of the exhaust cylinder 6052, and the second exhaust hole 6054 switches between inside and outside of the gas box 601 according to the volume of the expansion medium in the gas box 601.
It should be noted that the side wall of the air box 601 can also be rotatably connected with the inner wall of the installation box 1 through a bearing in the prior art.
In practical applications, to further enhance the usage effect, the first rod 603 presses the second sealing element 602 to discharge the expansion medium inside the air box 601 through the vent tube 6052, when the expansion medium is discharged, the first vent hole 6053 and the plurality of second vent holes 6054 on the vent tube 6052 are extended out of the interior of the air box 601 due to the discharge of the expansion medium, and the air is simultaneously discharged through the first vent hole 6053 and the second vent hole 6054, so that the air discharging speed is relatively high, after the air discharging is finished, the flexible expansion member 2 is to be supported to reset due to the elasticity of the first elastic connecting element 501, but when the tire moves by bumping, the outside of the flexible expansion member 2 is pressed, so that the flexible expansion member 2 on the side just pressed is pulled to expand, the flexible expansion member 2 pulls the first rod 603 to move out of the air box 601, so that the second sealing element 602 resets, the air box 601 pumps air into the interior of the air box through the vent tube 6052, but when the vent tube 6052 moves into the interior of the air box, so that the air can only pass through the first vent hole 603, so that the air pumping speed of the air box 601 can be limited, and the mounting position of the tire 405 cannot be limited, and the service life of the tire 405 cannot be limited.
In summary, the fixing mechanism for a spare tire of an automobile according to the second embodiment of the present invention has at least the following advantages compared to the fixing mechanism for a spare tire of an automobile according to the first embodiment:
1. in summer, because the installation box 1 is positioned in the trunk and is close to the exhaust distance of an engine, the internal temperature of the installation box 1 is increased, the vehicle jolts in the driving process, the spare tire jolts and moves in the driving process, the flexible expansion part 2 on one side is pressed when the spare tire moves, part of expansion medium in the expansion air chamber 3 is discharged at the moment, the flexible expansion part 2 extrudes the first rod body 603, the air box 601 rotates because the first rod body 603 is in threaded connection with the air box 601, the air box 601 drives the balancing weight 604 to rotate, and the balancing weight 604 vibrates because the balancing weight is uneven, the outer wall of the flexible expansion part 2 is driven to vibrate to be in vibration contact with the tire, so that the front contact is prevented from being damaged in friction all the time.
