Abstract
The utility model discloses a buffer block which comprises a metal framework, a bolt and rubber. The metal framework is of a cup shape, the opening of the metal framework is upward, the bottom of the metal framework is provided with a bolt hole, the head portion of the bolt is arranged in the bolt hole, a screw rod of the bolt extends downward from the inside of the bolt hole, the rubber comprises a body and a head portion disposed on the body, the body of the rubber is connected with the inside of the metal framework in an adhesive mode, and the head portion of the rubber extends upwards out of the opening of the metal framework. Initial impact and noise are little, and fatigue performance can be guaranteed.
Description
Technical field
The utility model relates to a kind of buffer stopper.
Background technique
At present, the buffer stopper that automobile chassis is used (stopper) mostly adopts pallet (or bottom skeleton) to add polyurethane or natural gum forms, and some are also arranged is gum or pure polyurethane.The purpose of damping rubber block is not for damping as other rubber dampers, but in order to relax impact, the damage parts that prevents the shock between different institutions while running into excessive load and cause, and metal parts (or other rigid elements) contacts and the noise of generation.
According to the difference of installation effect, damping rubber block can be divided into jumping buffer stopper and resilience buffer stopper.Because free travel is long, can guarantee the fatigue behaviour of product again when realizing passing the purpose of punching, existing buffer stopper is often done harderly, and the defect that this structure exists is:
1, the in the initial stage of that impact forces is larger, and the occupant can feel apparent in view impact;
2, hard rubber can cause producing noise in the buffering metal parts;
3, long free rubber stroke can make this part rubber produce deformation when being subject to load, and fatigue behaviour can not guarantee.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of buffer stopper, and initial impact and noise are all less, and fatigue behaviour can be guaranteed.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of buffer stopper, comprise metal frame, bolt, rubber,
Cup-shaped and the opening upwards of described metal frame, the bottom of described metal frame offers bolt hole,
The head of described bolt is arranged in bolt hole, and the screw rod of described bolt stretches out downwards in bolt hole,
The head that described rubber comprises main body and is arranged at the main body top, the main body of described rubber is adhered in metal frame, and the head of described rubber extends upward the oral area of metal frame.
Preferably, metal frame described in the utility model is formed or is stamped to form by carbon steel by aluminium die casting.
Preferably, the head of bolt described in the utility model is riveted on the screw hole of the bottom of metal frame.
Therefore compared with prior art, the utility model has following beneficial effect:
The cup-shaped design of metal frame, make rubber more than half be constrained in metal frame, be exposed at the outer rubber of metal frame and can play buffer function, when being subject to impact force, the outer rubber of metal frame down is out of shape to surrounding, can wrap metal frame, and as can not playing spacing effect by compressed metal frame, the maximum deformation quantity under impulsive load be can guarantee, collision and impact between metal parts prevented.Owing to adopting the metal frame as rigid body (to be wrapped up by rubber while being hit, guarantee not have and to contact between the metal frame of metal parts and buffer stopper) realize extremely spacing, padded coaming can be selected softer rubber or polyurethane, so can not feel impact the starting stage occupant who impacts, also can reduce well than ebonite and metal and impact the noise produced, simultaneously, because the rubber major part is restrained to metal frame, amount of deformation is improved, so fatigue behaviour can be guaranteed.
The accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
The structural representation that Fig. 1 is the utility model embodiment.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
Be illustrated in figure 1 the embodiment of a kind of buffer stopper described in the utility model, comprise metal frame 2, bolt 1, rubber 3, cup-shaped and the opening upwards of metal frame 2, the bottom of metal frame 2 offers bolt hole, the head of bolt 1 is arranged in bolt hole, and the screw rod of bolt 1 stretches out downwards in bolt hole, the head that rubber 3 comprises main body and is arranged at the main body top, the main body of rubber 3 is adhered in metal frame 2, and the head of rubber 3 extends upward the oral area of metal frame 2.Wherein, bolt 1 can be realized and being connected of automobile associated components, metal frame 2 is for bonding and constraint rubber 3, during use, rubber 3 bonding by Vulcanizations are in metal frame 2, metal frame 2 is fixed on automobile by bolt 1, may in upper jumping or springback process, collide metal parts, before may clashing into, can first realize metal parts the buffering of rubber 3 and metal parts in the vehicle movement process, if impact force is larger, can kill spacingly, prevent the shock of metal parts by metal frame 2 (now can be deformed rubber 3 parcel).
Preferably, in the present embodiment, metal frame 2 is formed or is stamped to form by carbon steel by aluminium die casting, can guarantee the intensity of metal frame 2.
Preferably, in the present embodiment, the head of bolt 1 is riveted on the screw hole of the bottom of metal frame 2, is connected relatively firm stable between bolt 1 and metal frame 2 like this.
The above technological scheme that the utility model embodiment is provided is described in detail, applied specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation is only applicable to help to understand the utility model embodiment's principle; , for one of ordinary skill in the art, according to the utility model embodiment, on embodiment and application area, all will change, in sum, this description should not be construed as restriction of the present utility model simultaneously.
