Example 1
The embodiment of the utility model provides an unlocking device for a front cover lock of an automobile, which comprises a front cover lock 100 and a secondary unlocking mechanism 200 as shown in figures 1-3; the front cover lock 100 includes a lock body 110 and a secondary locker 120, the secondary locker 120 being rotatably disposed on the lock body 110 to enable the secondary locker 120 to be switched between an unlocked position and a locked position with respect to the lock body 110; the secondary unlocking mechanism 200 is used to unlock the secondary lock catch 120.
Specifically, in the prior art, the front cover lock 100 is generally disposed on a radiator cross beam in an engine compartment of an automobile, a matching locking mechanism is disposed at a corresponding position on a cover body of the front cover, and the front cover lock 100 cooperates with the locking mechanism to lock the front cover. When the front hatch is opened, first-stage unlocking is carried out through a first-stage unlocking mechanism in the cab, the front hatch is slightly lifted, then second-stage unlocking is carried out through a second-stage unlocking mechanism 200, and the front hatch can be punched. Wherein the secondary unlocking is used to unlock the locked state of the secondary lock catch 120 on the front cover lock 100; the secondary shackle 120 is rotatably disposed on the lock body 110, and the rotation of the secondary shackle 120 enables the lock body 120 to be switched between a locked position (i.e., the secondary shackle 120 engages with the locking mechanism, and locks the front hatch) and an unlocked position (i.e., the secondary shackle 120 disengages from the locking mechanism, and opens the front hatch) with respect to the front cover lock 100.
In the embodiment of the present invention, as shown in fig. 1, the secondary unlocking mechanism 200 and the front cover lock 100 are separately disposed, the secondary unlocking mechanism 200 includes a connecting shaft 220 and a handle 210 connected to the connecting shaft 220, and the handle 210 can rotate relative to the body of the automobile through the connecting shaft 220; specifically, the connecting shaft 220 may be fixedly connected to one end of the handle 210, and may be rotatably connected to the body of the vehicle, and the handle 210 is driven to rotate relative to the body of the vehicle by the rotation of the connecting shaft 220; the connecting shaft 220 can also be rotatably connected with one end of the handle 210 and fixedly connected with the automobile body, and the handle 210 can rotate relative to the automobile body by rotating relative to the connecting shaft 220; any configuration and arrangement may be used as long as the handle 210 can be rotated with respect to the body of the automobile.
Further, the unlocking device for the automobile front cover lock 100 further comprises a pull wire 300, and the secondary unlocking mechanism 200 and the front cover lock 100 are connected with each other and driven through the pull wire 300; one end of the pull wire 300 is fixedly connected to the secondary lock catch 120, and the other end is fixedly connected to the handle 210, and the fixed connection can be realized by a clamping structure such as a ball head or a cylinder arranged at the end of the pull wire 300. When the handle 210 is rotated relative to the vehicle body in a first direction, i.e., arrow a shown in fig. 3, by an external force, the handle 210 pulls the pull wire 300 to move, so that the linkage secondary lock catch 120 is rotated from the locking position to the unlocking position in an unlocking direction, i.e., arrow B shown in fig. 1-2, relative to the lock body 110.
The front cover lock 100 is further provided with a return spring 111, and the return spring 111 is used for driving the secondary lock catch 120 to reset after rotating, namely the secondary lock catch 120 resets to a locking position after rotating to an unlocking position; specifically, the return spring 111, when in a normal compressed state, causes the secondary lock catch 120 to be in a locked position; rotation of the secondary latch 120 to the unlatched position causes the return spring 111 to extend. When the external force applied to the handle 210 is removed, the return spring 111 rotates the secondary lock catch 120 from the unlocking position to the locking position in a locking direction relative to the lock body 110, and rotates the handle 210 to the initial position in a second direction relative to the vehicle body through the pull wire 300; the second direction is opposite to the first direction A, and the locking direction is opposite to the unlocking direction B.
More specifically, the pulling wire 300 may be a rubber-sheathed steel wire; the handle 210 and/or the connecting shaft 220 of the secondary unlocking mechanism 200 may be plastic; the return spring 111 may be a conventional lock body spring with a large elastic coefficient, and its elasticity should enable the secondary lock catch 120 to pull the pull wire 300 to return the handle 210; for example, the spring constant of a typical lock spring is 30N/mm, and the return spring 111 of the present invention can be adapted to a spring having a spring constant of 40N/mm.
By adopting the scheme, the handle 210 and the front cover lock 100 are separated from each other by the pull wire 300, the handle 210 can be installed at a proper position of the automobile body by adjusting the trend of the pull wire 300 in the installation process, the difficulty of newly opening the handle 210 of the lock bodies 110 of different projects is avoided, the parts of different projects can be conveniently used, the unlocking device for the front cover lock of the automobile can adapt to different automobile models, the applicability is wider, and the cost is saved. The handle 210 can be installed outside the front compartment of the vehicle body, and can be used for opening the front compartment cover of the vehicle body conveniently when being used as an exterior trimming part and the like; and secondary unlocking mechanism 200 only adopts handle 210 and connecting axle 220, just can realize the secondary unblock to protecgulum lock 100, need not set up the part that kick-backs, and simple structure further has reduced the cost.
According to another specific embodiment of the present invention, as shown in fig. 1 and 3, the secondary unlocking mechanism 200 further includes a support 230, the connecting shaft 220 is disposed on the support 230, so that the handle 210 rotates around the axis of the connecting shaft 220 relative to the support 230, and the support 230 is fixedly connected to the body of the automobile.
