Description

Engine cover buckle structure
Technical Field
The invention relates to the technical field of engine covers, in particular to an engine cover buckling structure.
Background
The engine cover (also called engine cover) is the most striking body component, is one of the parts that buyers often want to see, and the main requirements for the engine cover are heat insulation and sound insulation, light weight and strong rigidity. When the engine cover is opened, the engine cover is generally turned backwards, and a small part of the engine cover is also turned forwards.
When the vehicle is in use, the engine cover is in a closed state and only needs to be opened during maintenance. The hasp of current bonnet, buckle structure mostly fixes a buckle on engine apron, fix elasticity buckle structure in the engine storehouse, and elasticity is detained the tongue (generally be the hook-like of invering) and at vertical plane internal rotation, when the bonnet is fashionable to the lower cover, the hasp pushes away the tongue earlier, after the lid closes in place, the tongue resets and the hasp block, it is spacing to carry out bonnet, this kind of fixed mode makes the bonnet in the certain elastic movement space of vertical direction, the in-process of traveling, arouse easily that the bonnet vibrates, collide with each other, lead to the noise to produce.
Disclosure of Invention
The invention aims to provide an engine cover buckling structure which is firm and stable in buckling, small in vertical vibration amplitude and compact and simple in structure after an engine cover is closed.
In order to solve the technical problems, the invention provides an engine cover buckling structure which comprises an installation support plate fixed on the inner surface of an engine cover, a rotating handle rotatably arranged on the installation support plate and a buckle fixed in an engine bin, wherein an elastic element is arranged between the installation support plate and the rotating handle, the elastic element enables the rotating handle to rotate and reset, and when the engine cover is closed, the end part of the rotating handle is clamped into the lower part of the buckle to realize buckling; when the engine cover is opened, the rotating handle is stirred to rotate along the horizontal direction, the end part of the rotating handle is far away from the lock catch to release the lock, and therefore the engine cover can be opened.
In the engine cover buckle structure, the buckle is fixed in the engine bin, the elastic buckle structure consisting of the rotating handle (equivalent to a buckle tongue in the background technology, but needs to be manually shifted to be opened) and the mounting support plate is fixed on the inner surface of the engine cover, and the rotating handle rotates in the horizontal plane, so that the end part of the rotating handle is clamped below the buckle after the engine cover is closed, the vertical direction is firmly clamped, the vertical vibration amplitude is small, and the collision and the noise of the engine cover and the wall of the engine bin are reduced. In addition, the whole structure is reliable to use, and can prevent the shells from being blocked caused by rusting and oil stains in the five-thousand functional test process, which is mainly reflected in the relation between the space structure and the position.
As an improvement of the engine cover buckling structure, the middle part of the installation support plate is concave, a groove structure for installing the rotating handle is formed, a through hole through which the buckle penetrates is formed in the groove bottom of the groove structure, a rotating shaft is rotatably arranged on one side of the through hole and is rotatably connected with the rotating handle, and the rotating handle can rotate on the groove bottom surface of the groove structure.
The middle groove structure of the installation support plate not only realizes good protection for the rotating handle and the like so as not to be interfered in the use process, but also reserves enough space for buckling the lock catch and the end part of the rotating handle, and the structural design is ingenious.

Among the above-mentioned technical scheme who adopts groove structure still open the spacing hole of arc on groove structure's the tank bottom surface, the last spacing flange that is provided with of twist grip, spacing flange is along with twist grip's rotation is in the spacing downthehole removal of arc, when removing one end, twist grip with the hasp lock, when removing to the other end, twist grip with the hasp is relieved the lock gradually.
The rotatable range of the rotating handle is limited through the arc-shaped limiting hole, and when the rotating handle is positioned at one end where the rotating handle is clamped with the lock catch, the rotating handle can be effectively and elastically limited by matching with the elastic element; the other end is convenient for manual operation, and suitable stirring angle is found, so that excessive and wrong stirring operation during manual stirring can be prevented effectively, the structure is more reliable, and the operation is convenient.
In the above technical scheme adopting the groove structure, the elastic element adopts a torsion spring, the main body of the torsion spring is arranged on the rotating shaft rod, one end of the torsion spring is fixed on the bottom surface of the groove structure, the other end of the torsion spring is abutted against the rotating handle, and the rotating handle is elastically blocked to rotate. The torsion spring is simple in structure, large in torsion force and capable of providing sufficient rotating restoring force, and meanwhile, when the engine cover covers, the rotating handle can be reliably limited.
Furthermore, be provided with first bending plate perpendicularly on groove structure's the bottom surface, it has the hanging hole to open on the first bending plate, with the one end of torsional spring articulates. One end of the torsion spring is hung and connected through the hole of the first bending plate, so that the installation is convenient
Furthermore, a second bending plate is arranged on the rotating handle, and the side face of the second bending plate is elastically abutted against the other end of the torsion spring. The other end of the torsion spring is directly and elastically abutted against the second bending plate, and the rotary handle is applied with elastic force, so that the structure is simple, and the installation is easy.
As another improvement of the engine cover buckling structure, the rotating handle is in a sickle-shaped plate-shaped structure and comprises a handle part and a buckling part, wherein the handle part is positioned on the sickle handle, the buckling part is positioned on the sickle head, a rotating fulcrum is arranged at the joint of the handle part and the buckling part and is in smooth transition, a third bending plate is arranged on the handle part, and the third bending plate is arranged perpendicular to the rotating plane of the rotating handle. Preferably, the lock catch is in an inverted L shape, and when the engine cover is closed, the horizontal section at the top end and the buckling part form up-down limit buckling.
The horizontal segment of hasp and the locking from top to bottom of the top surface of buckling parts lock, provide reliable, stable locking power, effectively reduce the upper and lower vibration of bonnet.
In conclusion, the engine cover buckling structure is compact and simple in structure, convenient to use and long in service life, and the engine cover is knocked and the noise is less in the running process of the whole vehicle due to vibration.
