Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings.
In the first embodiment, as shown in fig. 1, a low-pressure automatic tyre inflation device comprises an outer shell 1, a sliding sleeve 2 is fixedly connected to the bottom of an inner cavity of the outer shell 1, a movable cover 3 is arranged between the sliding sleeve 2 and the outer shell 1, a piston 4 is fixedly connected to the bottom end of the movable cover 3, the piston 4 is movably connected between the outer wall of the sliding sleeve 2 and the inner wall of the outer shell 1, a sealing cover 5 is movably connected to the upper side of the outer shell 1, an exhaust port 6 is arranged in the middle of the sealing cover 5, the exhaust port 6 is communicated with the inner cavity of the movable cover 3, and a first spring 7; a permanent magnet 8 is connected in the sliding sleeve 2 in a sliding manner, the upper surface of the permanent magnet 8 is fixedly connected with one end of a second spring 9, and the other end of the second spring 9 is fixedly arranged at the upper end of the movable cover 3; an air inlet one-way valve 10 is fixedly installed at the bottom of the sliding sleeve 2, an air outlet one-way valve 11 is fixedly installed at the lower end of the side surface of the sliding sleeve 2, an air outlet 12 is arranged at the lower end of the side surface of the outer shell 1, the air outlet 12 corresponds to the air outlet one-way valve 11 in position, and the air outlet 12 is communicated with a tire valve.
When the device is used, the device is fixedly arranged on a wheel axle of a tire, the air inlet one-way valve 10 faces the direction of a brake support, when the automobile tire runs slow air, the tire pressure can be gradually reduced, and because a cavity between the outer shell 1 and the sliding sleeve 2 which are positioned below the piston 4 is communicated with the tire air tap through the air outlet 12, the elastic pressure of the first spring 7 on the movable cover 3 is larger than the pressure of the tire air pressure on the piston 4, the movable cover 3 can move downwards under the elastic pressure of the first spring 7, the upper end of the second spring 7 between the movable cover 3 and the permanent magnet 8 is driven to move downwards to generate elastic pressure on the permanent magnet 8, the permanent magnet 8 slides downwards for a distance, and when the tire rotates to be close to the brake support, the magnetic attraction between the permanent magnet 8 and the brake support is larger than the elastic tension of the second spring 9, the permanent magnet 8 moves downwards along the sliding sleeve 2, when the tire rotates to be far away from the brake bracket, the magnetic attraction between the permanent magnet 8 and the brake bracket is reduced, the permanent magnet 8 can be pulled back to the upper part of the sliding sleeve 2 again under the action of the elastic tension of the second spring 9, the permanent magnet 8 can do piston motion on the sliding sleeve 2 by reciprocating in this way, and then the air enters and exits in one way through the air inlet one-way valve 10 at the bottom of the sliding sleeve 2 and the air outlet one-way valve 11 on the side surface, so as to realize the effect of automatically inflating the automobile tire, when the automobile tire is inflated to a certain amount, the tire pressure of the tire is increased, the pressure on the piston 4 at the end of the movable cover 3 is increased, so that the movable cover 3 is pushed to move upwards, and the permanent magnet 8 also moves upwards under the action of the elastic tension of the first spring 7, so that the magnetic attraction between the permanent magnet 8 and the brake bracket is reduced, and the phenomenon that the tire pressure is too large due to continuous inflation can be prevented; when the tire pressure is reduced again, the movable cover 3 moves downwards again, and the operation is repeated in such a way, so that the effect of automatic inflation can be realized when the tire runs slowly.
In the second embodiment, based on a further improvement of the first embodiment, a proper amount of antifreeze lubricant is filled between the moving cover 3 and the outer housing 1. The lubrication is mainly provided to the piston 4 at the end of the moving cover 3.
In the third embodiment, based on the further improvement of the second embodiment, a conical block 13 is fixedly installed on the outer surface of the exhaust port 6. When the moving cover 3 is moved upward, centrifugal force acts due to rotation of the tire to ensure that the antifreeze lubricant flies to the edge of the outer case 1 to prevent the antifreeze lubricant from being discharged from the exhaust port 6.
In a fourth embodiment, based on a further improvement of the first embodiment, a through hole is formed in the upper surface of the movable cover 3. So that the anti-freezing lubricating oil can enter the movable cover 3 through the through hole, and the movement of the stack of permanent magnets 8 plays a role in lubrication.
Fifth, based on the further improvement of the first embodiment, the auxiliary springs 14 are uniformly arranged on both sides of the second spring 9, and both ends of the auxiliary springs 14 are respectively and fixedly installed on the upper surface of the permanent magnet 8 and the upper surface of the inner cavity of the movable cover 3. The auxiliary spring 14 assists the pressing down of the permanent magnet 8, and the permanent magnet 8 can perform more stable piston movement in the slide sleeve 2.
Sixth embodiment, based on the further improvement of the first embodiment, a sliding groove 15 is fixedly installed on the outer side surface of the outer shell 1 near the axle center of the tire, an iron block 16 is movably connected in the sliding groove 15, and the iron block 16 is connected with the outer side surface of the outer shell 1 through a third spring 17. Because the tire is when rotating, permanent magnet 8 also can receive the effect of centrifugal force and paste 2 inner walls of sliding sleeve tightly, and then makes the frictional force between permanent magnet 8 and the 2 inner walls of sliding sleeve increase, causes the damage to 2 inner walls of sliding sleeve then, sets up iron plate 16 through being close to tire axle center position at permanent magnet 8, through the magnetic attraction between iron plate 16 and the permanent magnet 8 in order to overcome the centrifugal force that permanent magnet 8 received, and then reduced the frictional force between permanent magnet 8 and the 2 inner walls of sliding sleeve.
Seventh, according to a further improvement of the first embodiment, the brake further comprises an alarm, and the alarm is fixedly installed on the brake bracket. When the permanent magnet 8 moves towards the brake bracket, it indicates that the tire needs to be inflated, and at this time, the magnetism of the permanent magnet 8 triggers the alarm switch (in this embodiment, the contact of the alarm switch may be set to be made of iron, which is the prior art and thus is not described again), so as to remind the driver to select a proper time and place to repair the tire.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
