Description
Technical field
The invention belongs to damping appliance technology, more particularly to a kind of anti-displacement mechanism of damping.
Background technology
NVH performance requirements based on new energy vehicle to vehicle, in cabin interior, people's subjective sensation should not have pedal,
Steering wheel is shaken phenomenon, and must not have obvious abnormal sound etc. bad.Hereby, it is desirable to develop a brand-new damper, be used for
The shock insulation of the power source assembly such as ABS and EVP.
Current damping during use often due in order to protrude cushioning effect so that in damping
While employ excessive damping pattern so that product piece displacement is excessive in anticollision shock absorbing process, so as to cause with it is whole
The failure modes such as the other peripheral elements shocks of car.
The content of the invention
It is an object of the invention to solve the problems, such as techniques discussed above, there is provided for the purpose of one kind reduces damper stiffness,
Ensure its enough installation strength, ensure its reliability, improve the anti-displacement mechanism of damping of vehicle NVH performances, its technical scheme
It is as follows：
The anti-displacement mechanism of damping, it is characterised in that including damper and bolt, peace is offered on the outer surface of described damper
Tankage, endoporus is offered at the center of damper, the cavity of staggered cross setting is offered on damper；The one of described bolt
Endoporus is passed after the endoporus of end insertion damper；Described bolt includes threaded area, ring flange, supporting section and diameter segment, described
Ring flange be the positioning of press fitting damper end, described supporting section with the endoporus of damper is tangent contacts, support whole whole
The weight of individual device；Described diameter segment is located in endoporus and is in gap state with the endoporus of damper.
Preferred embodiment is that described endoporus is hexagonal hole.
Preferred embodiment is that the gap between described endoporus and diameter segment is 1mm.
The anti-displacement mechanism of damping provided by the invention, when in use, the setting of cavity be in order to reduce rigidity in terms of,
Reduce the rigidity at its mounting groove.The setting of endoporus is more yielding in terms of structural principle, only allows damper to have enough
Elastic deformation space, good shock-absorbing can be played.
Ring flange of the present invention is the positioning of press fitting damper end, and its function of supporting section is tangent with damper hexagonal inner hole
Contact, support the weight of whole product piece；Diameter segment is in gap state with damper hexagonal inner hole, and major function is realized,
In product piece startup, it is stopped moment, vibrations are larger, need damper to have enough deflections to absorb energy impact, meanwhile,
Prevent that the displacement of product piece is excessive again, cause the failure modes such as peripheral elements shocks other with vehicle.
The beneficial effects of the invention are as follows：For the purpose of reducing damper stiffness, ensure its enough installation strength, ensure that it can
By property, vehicle NVH performances are improved.

Embodiment
With reference to Fig. 1 to Fig. 4 specific illustrative embodiments：
Low rigidity damping device, including damper 2, product piece 1, support 3 and bolt 4, described damper 2 are arranged at support 3
Between product piece 1；Mounting groove 24 is offered on the outer surface of described damper 2, endoporus is offered at the center of damper
21, the cavity 23 of staggered cross setting is offered on damper；Bracket holes are provided with described support 3, damper passes through peace
Tankage 24 is placed in bracket holes, is connected to after one end of bolt is inserted into the endoporus of damper in product piece.
Preferred embodiment is that described bolt includes threaded area 43, ring flange 42, supporting section 41 and diameter segment 44, described
Ring flange is the positioning of press fitting damper end, described supporting section with the endoporus of damper is tangent contacts, support whole
The weight of device；Described diameter segment is located in endoporus and is in gap state with the endoporus of damper.
Preferred embodiment is that described endoporus is hexagonal hole.
Preferred embodiment is that reinforcement 22 is provided with described damper.
Preferred embodiment is that described cavity is fan-shaped chamber.
Shock absorber structure designs, and in terms of reducing rigidity, is respectively provided with the fan-shaped chamber of opposed staggered cross depth, makes
Rigidity at its mounting groove 24 reduces, meanwhile, to ensure its rubber structural strength, design structure reinforcement 22, and guarantor will
After the mounting groove groove of damper loads the hole of support 3, both ends rigidity is larger, and its support 3 is not easy to come off at mounting groove 24.Meanwhile
The endoporus 21 for designing damper is hexagon, more yielding in terms of structural principle, only allows damper to have enough elasticity changes
Shape space, good shock-absorbing can be played.
The structure design of bolt 3, threaded area 43 may be directly threaded into the screwed hole of installation product piece, by the platform of thread head
Rank positions, and ring flange is the positioning of press fitting damper end；Supporting section, its function are the hexagonal inner hole phase cut-graftings with damper
Touch, support the weight of whole product piece；The hexagonal inner hole of diameter segment and damper is in gap state, and major function is realized,
In product piece startup, it is stopped moment, vibrations are larger, need damper 2 there are enough deflections to absorb energy impact, together
When, prevent that the displacement of product piece is excessive again, cause the failure modes such as peripheral elements shocks other with vehicle；
During assembling, damper 2 is loaded in the hole of support 3 first, its mounting groove 24 is effectively caught in bracket holes；Bolt 4 is inserted again
Enter damper 2, be directly threaded into the respective screw hole of product piece 1.Support 3 is directly connected with vehicle body, and then it is good every
Shock stability.Incompetent horizontal direction or side direction installation, ensure the reliability and shock insulation rate of its installation.
