Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Examples
Referring to fig. 1 to 4, the automobile shock absorption suspension bracket of the embodiment includes a mounting base 1, a connector 2, and a spring body 3 disposed between the mounting base 1 and the connector 2, the top of the mounting base 1 is connected with a hollow tube 4, the bottom of the connector 2 is connected with a top disc 8, a connection post 9 is connected between the top disc 8 and a movable part 5, the top of the hollow tube 4 is provided with an opening, the connection post 9 is arranged in the opening in a penetrating manner, the spring body 3 is connected between the top disc 8 and the mounting base 1, the bottom of the connector 2 is provided with the movable part 5, the movable part 5 is a disc, the surface of the disc is connected with a sealing element 7, the disc is movably connected with the hollow tube 4 in a sealing manner through the sealing element 7, and a first cavity 6 is formed among the movable part 5, the bottom of an inner cavity of the hollow tube 4, and the mounting base 1; as shown in fig. 4, when the movable element 5 moves downward to compress the air in the first cavity 6, the air pressure in the cavity of the first cavity 6 increases to limit downward movement of the movable element 5;
the device is arranged between a frame and a wheel through a mounting seat 1 and a connector 2, when the wheel moves to an uneven road surface, the connector 2 drives a top disc 8 to move up and down under the action of a spring body 3, the vibration of the wheel can be buffered through the spring body 3, when the connector 2 drives a movable piece 5 to move downwards, air in a first cavity 6 can be compressed through the movable piece 5, along with the downward movement of the movable piece 5, the air pressure in the first cavity 6 is increased, the movable piece 5 can continue to move downwards only by needing larger downward pressure, because the pressure applied by a vehicle body is limited, when the pressure at the top of the movable piece 5 does not enough drive the movable piece 5 to move downwards when the movable piece 5 moves downwards to a certain position, the movable piece 5 stops, so that the compression of the spring body 3 can be limited by compressing the air in the first cavity 6 through the movable piece 5, the compression of the spring body 3 is effectively prevented from exceeding the elastic modulus, the protection of the spring body 3 can be realized, and the service life of the damping suspension bracket is prolonged;
the ascending reaction force that receives when moving part 5 moves down in this scheme is slow increase, not only can further improve the buffering effect of this device, and can contact moving part 5 and mount pad 1 bottom effectively, if set up hollow tube 4 bottom into with external looks general formula, set up moving part 5 into can with mount pad 1 bottom contact, although can restrict spring body 3's compression, but in the twinkling of an eye when moving part 5 and mount pad 1 contact, can produce great impact force in the twinkling of an eye between connector 2 and the mount pad 1, not only probably play good shock attenuation effect, and still can cause the damage to frame and wheel, so this scheme is preferred scheme as.
A second cavity 10 is formed between the connecting column 9 and the top of the inner cavity of the hollow tube 4, and pressure relief ports 11 distributed in an annular array are formed in the top of the hollow tube 4, so that the second cavity 10 is communicated with the pressure relief ports 11, pressure relief treatment on air pressure in the second cavity 10 can be realized through the pressure relief ports 11, and the moving part 5 is effectively prevented from being greatly limited in movement.
