Description
Technical field
The utility model relates to a kind of automotive lock, especially a kind of retaining mechanism of front engine cover of car belongs to lockset technology
Field.
Background technique
Currently, existing front engine cover of car lockset, the first lock position generally use independent snap-gauge and engage with lock pawl
It realizes, the second lock position generallys use the safety door hook realization independently of the first lockable mechanism.It is asked existing for this locking mechanism
Topic is that structure is complicated, and number of parts is more, high production cost.
Summary of the invention
The utility model is intended to provide a kind of retaining mechanism of preceding hood lock, which stops only with a snap-gauge and one
Two grades of lock-bits can be realized in pawl, and structure simple and compact, stable operation is reliable, reduce production cost, improve assembly efficiency and lock
The stability of body structure.
The utility model is achieved through the following technical solutions:
The retaining mechanism of preceding hood lock comprising:
First axle 4 and the second axis 5, and
It is respectively arranged in first axle 4 and rotation snap-gauge 1 and lock pawl 2 on the second axis 5；
It is characterized in that,
The rotation snap-gauge 1 includes
In the first lock position, the engaging section 1-3 cooperated with lock pawl 2 and the first lock-bit slot 1- for limiting lock pin 3
1；
In the second lock position, the second lock-bit slot 1-2 that lock pin 3 disengages is limited.
Under preceding hood lock locking states, rotation snap-gauge 1 engage with lock pawl 2, and lock pin 3 is positioned at rotating the of snap-gauge 1 at this time
In one lock-bit slot 1-1, rotation snap-gauge 1 is located at the first lock position；
Under preceding hood lock unlocked state, rotation snap-gauge 1 is disengaged from lock pawl 2, and preceding cover is bounced with pendulum lock pin 3 from the
One lock-bit slot 1-1 moves outwardly and into the second lock-bit slot 1-2, and rotation snap-gauge 1 is located at the second lock position.
The first lock-bit slot 1-1 is in fish mouth mouth shape, and at the first lock position, for oral area towards side, lock pin 3 is secured
It is reliably limited in fish mouth mouth.
The opening ways of the lock pawl 2 use bracing wire unlatching or electric opening；
The rotation snap-gauge 1 realizes that unlock is opened by the rotation of lock pin at the second lock position；
It is equipped with snap-gauge position limiting structure 6 in the side of rotation snap-gauge 1, which rotates for limiting rotation snap-gauge 1 in locking
Reverse movement.
The retaining mechanism of the preceding hood lock of the utility model, simple structural design is reasonable, by the first, second traditional lock
Only function is integrated in the same rotation snap-gauge, and is laid out different function parts by optimization to realize that the safety of preceding hood lock opens
It closes, provides the organization plan of relative simplicity, lock body is stable and reliable for performance, has saved production cost, improves assembly efficiency, subtracts
Few lock body components composition, space optimization mitigate lock body weight.
Detailed description of the invention
Fig. 1: the retaining mechanism schematic diagram of hood lock before the utility model；
Fig. 2: rotation clamp structure schematic diagram；
In figure, 1, rotation snap-gauge, 1-1, the first lock-bit slot, 1-2, the second lock-bit slot, 1-3, engaging section, 2, lock pawl, 2-
1, lock pawl engaging section, 3, lock pin, 4, first axle, the 5, second axis, 6, snap-gauge position limiting structure.
Specific embodiment
Below in conjunction with attached drawing 1-2, specific embodiment of the utility model is provided, is used to preceding cover a kind of to the utility model
The structure composition and design principle of the retaining mechanism of lock are described in further detail.
Embodiment one
A kind of retaining mechanism of preceding hood lock, is installed on front engine cover of car and locks, to realize the opening and closing of preceding hood lock,
Structure includes first axle 4 and the second axis 5, and is rotatablely installed respectively in the rotation snap-gauge 1 in first axle 4 and the second axis 5 and is stopped
Pawl 2；The rotation snap-gauge 1 has the first engaging section 1-3 engaged in the first lock position with lock pawl 2 and for limiting
First lock-bit slot 1-1 of lock pin 3；The second lock-bit slot 1-2 that limitation lock pin 3 disengages in the second lock position.Preceding hood lock locking
Under state, the engaging section 1-3 of rotation snap-gauge 1 is engaged with the lock pawl engaging section 2-1 of lock pawl 2, and lock pin 3 is located at revotating card at this time
In first lock-bit slot 1-1 of plate 1, rotation snap-gauge 1 is located at the first lock position；Under preceding hood lock unlocked state, rotation snap-gauge 1 with
Lock pawl 2 is disengaged from, and preceding cover bounces band pendulum lock pin 3 and moves outwardly and into the second lock-bit slot 1- from the first lock-bit slot 1-1
2, rotation snap-gauge 1 is located at the second lock position.The first lock-bit slot 1-1 is in fish mouth mouth shape, at the first lock position, oral area
Towards side, lock pin 3 is limited in solid and reliablely in fish mouth mouth.The lock pawl 2 has to be engaged with the first of rotation snap-gauge 1
The claw that portion 1-3 is meshed, and the bracing wire connecting pin for connecting stay wire；The opening ways of the lock pawl 2 use bracing wire
Unlatching or electric opening；Opening ways of the rotation snap-gauge 1 on the second lock position are rotarily opened using lock pin, pass through lock
The unlock of pin rotated to realize rotation snap-gauge.
The retaining mechanism of the preceding hood lock of the utility model, simple structural design is reasonable, by the first and second traditional locking
Function is integrated in the same rotation snap-gauge, and is laid out different function parts by optimization to realize that the safety of preceding hood lock opens
