The working principle of the invention is as follows:
(1) in use, the first connecting member 1 is connected to the lower part of the vehicle. When the vehicle vibrates, pressure is applied to the first connecting piece 1, the first connecting piece 1 transmits acting force to the first vibration damping frame 2, the first vibration damping frame 2 further transmits the vibration damping seat 3, meanwhile, the lower end of the first connecting piece 1 extrudes the cross beam 6, and the cross beam 6 further transmits the acting force to the auxiliary vibration damping frame 5. In the process, the first vibration damping frame 2 and the auxiliary vibration damping frame 5 support and damp the wheel at the same time, and stable support of the wheel is ensured. First damping frame 2 and supplementary damping frame 5 disperse the effort, avoid the vehicle to lead to the fact the damage of bumper shock absorber to the effort of bumper shock absorber too concentrated.
(2) The side wall of the first mounting hole 222 is concavely provided with a thread, and the rubber rod 21 is screwed to the first mounting hole 222. The buffer block 224 is made of rubber material. When the force of the first connecting member 1 is transmitted to the damping frame 2, the force is further transmitted to the cushion socket 22. A force acts on the buffer blocks 224 in the axial direction of the buffer base 22, and the plurality of buffer blocks 224 are deformed by the axial pressing force to cope with the pressing action. The bumper block 224 absorbs the extrusion force by deforming while the shock absorber itself plays a protective role. A plurality of buffer blocks 224 adopt split type structure, avoid the effort direct action to lead to its buffer block 224 to appear seriously warping when bearing great effort at a buffer block 224, and then lead to automobile shock absorber ware to damage.
A plurality of buffer bases 22 bear certain axial extrusion force respectively, and each buffer base 22 produces certain deformation respectively and absorbs the extrusion force in order to reduce the damage that the extrusion caused, avoids the effort to concentrate on a buffer base 22 and leads to the automobile shock absorber ware to damage.
(3) In use, the buffer cover 31 and the buffer barrel 33 are in a group, and the buffer seat 22 is arranged between the two adjacent buffer covers 31 and buffer barrels 33. The positioning ring 313 is tightly pressed in the positioning groove 221, and the positioning and installation of the buffer cover 31 and the buffer seat 22 are realized through the matching of the positioning groove 221 and the positioning ring 313.
The buffer seat 22 is inserted into a buffer cavity defined by a plurality of supporting blocks 332 along the axial direction of the housing 331, and the buffer block 224 is pressed against the supporting blocks 332. When the buffer block 224 is pressed, the pressing force is transmitted to the supporting block 332, and the pressing force applied to the supporting block 332 is resolved in the axial direction and the radial direction of the supporting block 332, respectively, and the corresponding supporting block 332 is deformed in the axial direction and the radial direction, respectively. When the supporting blocks 332 are deformed in the radial direction, the plurality of supporting blocks 332 are deformed and dispersed outward; when the support blocks 332 are deformed in the axial direction, the plurality of support blocks 332 are deformed and press the carrier plate 333, respectively, according to the axial pressure received. The support block 332 absorbs the pressing force by its own deformation, moderates the impact, and protects itself. The supporting blocks 332 are of a separated structure, each supporting block 332 generates small deformation to play a buffering role, the phenomenon that the supporting block 332 is damaged due to large deformation when acting force is concentrated on one supporting block 332 is avoided, and the combined type new energy automobile shock absorber can be protected.
The rubber strip 3321 is made of a rubber material. After the buffer block 224 is pressed on the rubber strip 3321, the rubber strip 3321 deforms under the action of the pressing force, so that the buffer effect is achieved. Meanwhile, the acting force transmitted to the supporting block 332 through one buffering block 224 is respectively absorbed by the plurality of rubber strips 3321, each rubber strip 3321 correspondingly generates certain deformation to absorb the extrusion force, and the single rubber strip 3321 can play a good buffering role only by small deformation. After the squeezing force disappears, the rubber strip 3321 returns to its original state. The rubber strips 3321 are hinged to each other, and after the squeezing force is removed, the rubber strips 3321 restore to the original shape again to form a complete supporting plane.
The bearing block 3322 is made of steel materials, and has high strength and strong bearing capacity. When great effort is transmitted to on bearing block 3322, it can be fine plays the supporting role, ensures the stable in structure of buffer cylinder 33, can not appear warping or damaging because of great extrusion force.
(4) The first vibration damping member 524 includes a tubular supporting cylinder, a rod-shaped rubber supporting rod is slidably disposed on the upper portion of the supporting cylinder along the axial direction of the supporting cylinder, and the second spring is sleeved on the rubber supporting rod and tightly pressed on the top end of the supporting cylinder. One end of the rubber support rod extending out of the support cylinder is screwed to the first rubber plate 523 by threads, and the second spring is tightly pressed on the first rubber plate 523.
When the support rod 511 is used, the support rod 511 sequentially penetrates through the sealing cover 521, the cylinder 522 and the first rubber plates 523, and the second gasket 513 is located between the two first rubber plates 523.
A buffer space is enclosed between the first rubber plate 523 and the sealing cover 521, the two first gaskets 512 are positioned in the buffer space, the first gaskets 512 are pressed on the first rubber plate 523, and the second gaskets 513 are pressed between the two first rubber plates 523.
The first gasket 512 and the first rubber plate 523 are both made of a rubber material. The pressure transmitted to the support rod 511 pushes the support rod 511 to slide along the inner cavity of the cylinder 522, the support rod 511 drives the support rod 511, the first gaskets 512 and the second gaskets 513 to slide along the cylinder 522, the first gaskets 512 push one first rubber plate 523, the two first rubber plates 523 push the second gaskets 513 from two ends, and the other first rubber plate 523 pushes the first gaskets 512. In the process, the support rod 511, the first gasket 512, the second gasket 513 and the first rubber plate 523 respectively generate corresponding deformation to absorb the extrusion force, so as to play a good buffering role.
