Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figures 1 to 4, this engine bonnet, including ontology 100 are provided through at least one peace along ontology 100
Notch is filled, installation gap is passed through for engine components, and the outer of each installation gap is coated with damping layer, damping layer and ontology
100 are integrally formed.
By the way that ontology 100 and damping layer to be integrally formed, specifically, first by 100 injection molding of ontology, then in ontology
On the basis of 100, in predeterminated position injection molding damping material to form damping layer, so that engine bonnet is only needed by being molded work
Skill is just disposable to complete production, is not necessarily to man-made assembly, saves cost of labor, and high production efficiency.In addition, being filled relative to the later period
The rubber ring matched, damping layer and the ontology 100 of injection molding cooperate it is even closer, be not easy loosen and sealing performance it is more preferable, improve
Product quality.
In the present embodiment, preferably main body is nylon material, and damping layer is rubber material, so that engine bonnet is guaranteeing to tie
Under the premise of structure intensity, overall weight is lighter, and rubber vulcanization process is mature, effectiveness in vibration suppression is effectively ensured, manufacturing cost is low.
Installation gap includes axis hole 110, and along axis hole 110, recess is formed with first step 111 downwards, and the damping layer includes
Damping ring 200 corresponding with axis hole 110, damping ring 200 are equipped with annular notch 210 corresponding with first step 111, First
In 111 embedded rings v notch v 210 of rank, and the two sides up and down of first step 111 and inner wall are close to annular notch 210.
By setting first step 111 and annular notch 210, so that damping ring 200 and the cooperation of axis hole 110 more step up
It is close, when engine components are vibrated relative to axis hole 110, effectively avoid damping ring 200 from sliding relative to axis hole 110 even de-
Out, reliability is more preferably.
Preferably, the diameter of damping ring 200 is identical as the diameter of axis hole 110, to pass through axis hole 110 and damping ring 200
Dimensional fits, limit 200 horizontal displacement of damping ring, guarantee damping ring 200 and axis hole 110 cooperation compactness.
In addition, the quantity of axis hole 110 is two and is symmetrically disposed on the left and right sides of ontology 100, which is arranged such that
When engine operation, partial vibration can cancel out each other, and effectiveness in vibration suppression is more preferably.
It is additionally provided with the first connecting column 220 in annular notch 210, the first connecting column 220 connects up and down the two of damping ring 200
Side is correspondingly arranged on the through-hole passed through for the first connecting column 220 on first step 111.
By the way that the first connecting column 220 is arranged, so that damping ring 200 and ontology 100 form an entirety, in engine bonnet
After molding, in addition to destructiveness is removed, damping ring 200 can not be detached from ontology 100 completely, take full advantage of the spy of injection molding process
Point further increases the cooperation compactness and integrality of damping ring 200 Yu axis hole 110, further increases reliability.
It is preferred that the quantity of the first connecting column 220 is multiple and is arranged circumferentially along annular notch 210, so that axis hole 110
And range more uniform to the binding effect of damping ring 200 is bigger, even if elasticity change occurs for the one side or the multi-lateral in damping ring 200
Shape can also be easy to restore to initial makeup location, better reliability.
The inner wall of damping ring 200 is equipped with skirt 230, and the overall size of skirt 230 is started less than what damping ring 200 was passed through
Machine component.
When damping ring 200 passes through engine component, skirt 230 occurs flexible deformation and tensioner and can be with engine components
Shake and move up and down, always sealing both junction, to guarantee the sealing effect of damping ring 200.
Installation gap further includes the groove 120 of a side opening, and along 120 downside of groove, recess is formed with second step upwards
121, the damping layer further includes vibration-damping sheet 300 corresponding with groove 120, and vibration-damping sheet 300 is equipped with corresponding with second step 121
Annular notches 310, second step 121 is embedded in annular notches 310, and the two sides up and down of second step 121 and inner wall are tight
Annular notches 310 are pasted, are also evenly arranged with several the second connecting columns 330, the connection of the second connecting column 330 along annular notches 310
The two sides up and down of vibration-damping sheet 300 are correspondingly arranged on the through-hole passed through for the second connecting column 330 on second step 121.
Vibration-damping sheet 300 at existing groove 120 is usually plugged with ontology 100 and is connected, and when man-made assembly is difficult vibration damping
Piece 300 is disposably inserted into position, and gap is larger between vibration-damping sheet 300 and ontology 100, is easy to loosen, or deviate from along opening.It is based on
Aforementioned axis hole 110, the same production principle of damping ring 200, the cooperation of above-mentioned groove 120 and vibration-damping sheet 300 are same to efficiently use
The characteristics of integrated formed structure, effectively reduces cost of labor, and firmness more leakproofness is more, improves product quality.
It is sloped downwardly along vibration-damping sheet and has been bent to form sealing 320, the downside of sealing 320 and vibration-damping sheet
Downside flushes setting.
By sealing 320, so that vibration-damping sheet is fitted close with engine components always when engine luggine, guarantee close
Effect is sealed, and tilts the sealing 320 of bending structure, the elastic deformability of sealing can be effectively improved, expands it and transports up and down
Dynamic range, more preferable with the fiting effect of engine components, compatibility is more preferably.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
