Description

Novel two sectional type automobile engine cover locks mechanism

Technical field

The utility model relates to a kind of automobile engine cover and locks mechanism, and especially a kind of two sectional type automobile engine cover locks mechanism.

Background technology

Present two sectional type automobile engine cover (or cover) lockout mechanism is forward and backward split setting, and volume is big like this, is unfavorable for oversimplifying assembling, and the long-term use reliability of structure is lower.

Summary of the invention

In order to address the above problem, the utility model provides a kind of novel two sectional type automobile engine cover locking mechanism, this lockout mechanism volume is little, be beneficial to oversimplify assembling and the long-term use reliability higher.

The utility model for the technical scheme that solves its technical matters and adopt is: a kind of novel two sectional type automobile engine cover locking mechanism, grapple and back hook concentric are articulated in the main body, lock hook is articulated in the main body, the keyed end opening of lock hook just can be equipped in an end opening inboard of grapple near an inboard of grapple, the keyed end opening of lock hook plugs the location for the stirrup hook on the snap close, and the keyed end opening of lock hook just can coincide with body openings and can be one side closed by body openings fully;

One end of back hook is for colluding end, colluding end just can be in the body openings, back hook collude end than the keyed end opening of lock hook exit near body openings, the end that colludes of back hook is formed with the stirrup dogging that is beneficial on the snap close towards a side of body openings and goes into the inclined-plane of main body opening;

Be provided with first and second spring, the neutralize shoulder of its other end resilient abutment grapple one end of first spring, one end resilient abutment main body, described shoulder is an end opening of grapple dorsad;

Second spring, one end colludes in the end back side and its other end resilient abutment main body against the back hook;

Be provided with a dead man again, dead man elasticity articulates (having reset force to exist when promptly rotating) in the main body another side, arcuate socket on the main body is passed in the end activity of pulling out of dead man just can stir the other end of grapple (thereby an end opening that makes grapple is away from the keyed end opening of the keyed end opening lock hook of lock hook and is opened on body openings, makes stirrup hook on the snap close deviate from the keyed end opening and enters in the body openings);

Be provided with a trigger bar, trigger bar elasticity is articulated in the main body another side, and the end activity of stirring of trigger bar one end just can be stirred the back hook other end (make the end that colludes of back hook remove body openings, the stirrup hook on the snap close is removed body openings, thereby opens bonnet) after passing main body;

Be provided with a pin, pin is axially (axially referring to and itself) elasticity to be located in the main body, and the end that pin exposes main body is towards body openings direction (when being used for stirrup hook on the snap close and removing body openings, jack-up bonnet) automatically.

The beneficial effects of the utility model are: all parts of this example all are located on the main body, and simple in structure, like this lockout mechanism volume little, be beneficial to oversimplify assembling and the long-term use reliability higher.

The specific embodiment

Embodiment: a kind of novel two sectional type automobile engine cover locks mechanism, grapple 1 and back hook 2 concentrics are articulated in the main body 4, lock hook 3 is articulated in the main body 4, the keyed end opening 13 of lock hook 3 just can be equipped in an end opening 11 inboards of grapple 1 near an inboard of grapple 1, the keyed end opening 13 of lock hook 3 plugs the location for the stirrup hook on the snap closes, and keyed end 13 openings of lock hook 3 just can coincide with body openings 14 and can be one side closed by body openings 14 fully;

One end of back hook 2 is for colluding end 12, colluding end 12 just can be in the body openings 14, back hook 2 collude end 12 than the keyed end opening 13 of lock hook 3 exit near body openings 14, the colluding of back hook 2 holds 12 sides towards body openings 14 to be formed with the stirrup dogging that is beneficial on the snap close to go into the inclined-plane of main body opening 14;

Be provided with the shoulder 10 of first and

second spring

5,6, the first springs 5 one end resilient abutment main bodys 4 its other end resilient abutment grapple 1 one ends of neutralization, described shoulder 10 is an end opening 11 of grapple 1 dorsad;

Second spring, 6 one ends collude in end 12 back sides and its other end resilient abutment main body 4 against back hook 2;

Be provided with a dead man 7 again, dead man 7 elasticity articulate (having reset force to exist when promptly rotating) in main body 4 another sides, arcuate socket on the main body 4 is passed in end 71 activities of pulling out of dead man 7 just can stir the other end of grapple 1 (thereby an end opening 11 that makes grapple 1 is away from the keyed end opening 13 of keyed end opening 13 lock hooks 3 of lock hook 3 and is opened on body openings 14, makes stirrup hook on the snap close deviate from keyed end opening 13 and enters in the body openings 14);

Be provided with a trigger bar 8, trigger bar 8 elasticity are articulated in main body 4 another sides, the end activity of stirring of trigger bar 8 one ends just can be stirred back hook 2 other ends (make the end 12 that colludes of back hook 2 remove body openings 14, the stirrup hook on the snap close is removed body openings 14, thereby opens bonnet) after passing main body 4;

Be provided with a pin 9, pin 9 is axially (axially referring to and itself) elasticity to be located in the main body 4, and the end that pin 9 exposes main body 4 is towards body openings 14 directions (when being used for stirrup hook on the snap close and removing body openings 14, jack-up bonnet) automatically.

Course of action of the present utility model is:

One, supposes that bonnet is closure state

The car inhaul makes dead man 7 rotations, dead man 7 pull out the other end that end 71 is stirred grapple 1, grapple 1 is rotated, thereby an end opening 11 of grapple 1 is not fastened away from the keyed end opening 13 of lock hook 3, the end opening 11 of keyed end opening 13 and grapple 1 that makes lock hook 3, keyed end opening 13 is and is opened on body openings 14, makes stirrup hook on the snap close deviate from keyed end opening 13 and enters in the body openings 14;

Then stir trigger bar 8, the bar of stirring of trigger bar 8 is stirred the other end of hook 2 afterwards, and back hook 2 is rotated, shift out body openings 14 from the end 12 that colludes of hook 2 then, stirrup hook on the snap close is extensible body openings 14, thereby opens bonnet, pin 9 automatic jack-up bonnets.

Two, suppose that bonnet is opening

Put down bonnet earlier, stirrup hook on the snap close is run into colluding of back hook 2 and is held 12 inclined-planes, stirrup hook on the snap close is clamp-oned body openings 14 along the inclined-plane, second spring 6 by compression at this moment, after stirrup hook on the snap close is clamp-oned body openings 14, second spring 6 resets, and again the end 12 that colludes of back hook 2 is pushed the stirrup hook disengaging body openings 14 that stops in the body openings 14 on the snap close

Then, stirrup hook on the snap close enters the keyed end opening 13 of lock hook 3 along body openings 14, the keyed end opening 13 that stirrup hook on the snap close pushes away lock hook 3 is clamp-oned in the end opening 11 of grapple 1 keyed end opening 13 1 sides of lock hook 3, clamp-on in the process first spring 5 by compression, after clamp-oning, first spring 5 resets, the keyed end opening 13 of lock hook 3 engages mutually with an end opening 11 of grapple 1, stirrup hook on the snap close just is positioned keyed end opening 13 and has suffered (this moment, the keyed end opening 13 of lock hook 3 was one side closed by body openings 14) like this, bonnet just is closure state, and pin 9 is in the elastic compression shape.
