Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the utility model provides an energy absorber, including outer solid fixed cylinder 3, energy-absorbing rubber spare 2 and striking bearing 1, 3 one end fixed connection of outer solid fixed cylinder on the platform, the other end passes through inner wall and energy-absorbing rubber spare 2 fixed connection, establishes the mounting groove at energy-absorbing rubber spare 2 middle part, and striking bearing 1 is fixed in the mounting groove of energy-absorbing rubber spare 2, and striking bearing 1's outer end bulges energy-absorbing rubber spare 2.
Referring to fig. 2, before the collision, the impact bearing member 1 is at the initial position, and when external force collides with the energy absorber provided by the present invention, the impact bearing member 1 generates vertical, horizontal displacement under the effect of the external impact force, and to the working position, the impact bearing member 1 transmits energy to the energy absorbing rubber member 2, and since the energy absorbing rubber member 2 is made of flexible material, the energy is absorbed by the energy absorbing rubber member 2, so that rigid collision cannot occur.
Referring to fig. 2, in order to form a stable connection between the impact receiving member 1 and the outer fixing tube 2, as a modification, the energy absorbing rubber member 2 includes a first rubber portion 201 fixedly connected to the outer fixing tube 3, a second rubber portion 202 fixedly connected to the impact receiving member 1, and a third rubber portion 203 located between the first rubber portion 201 and the second rubber portion 202; the mounting groove on the energy-absorbing rubber member 2 is arranged in the middle of the second rubber part 202, and the lower end of the mounting groove is provided with a hole with a diameter smaller than that of the mounting groove.
The installation groove lower extreme trompil is mainly for when the installation strikes bearing member 1, can not produce great atmospheric pressure in the installation groove to lead to striking bearing member 1 not to install the bottom in the installation groove, form unstable connected relation.
Referring to fig. 2, in order to absorb energy to the maximum extent and to prolong the service life of the energy-absorbing rubber member 2, as a technical improvement, the cross section of the sidewall of the third rubber portion 203 is a nearly parallelogram, and the trend of the oblique side of the parallelogram is upward from the end connected with the first rubber portion 201 to the end connected with the second rubber portion 202.
