Embodiment 1

[0048] Such as figure 1 , the driving mechanism is a drag cable 6, and the drag cable 6 is connected with the ratchet 2 and pulls the ratchet 2 to move.

Embodiment 2

[0050] The driving mechanism is an electric unlocking mechanism 7 . Wherein, the electric unlocking mechanism 7 and the ratchet 2 can be connected by a drag cable 6 . Or use the following two methods: The first method: such as Figure 13 , the pawl 2 is fixed with a special connector 8, and the electric unlocking mechanism 7 is snapped connected with the special connector 8; the second way: as Figure 14-15 , The electric unlocking mechanism 7 is connected with a ball head 9, and the pawl 2 is provided with an arc-shaped groove 10 matching with the ball head 9. This structure can reduce friction.

Embodiment 3

[0052] The driving mechanism includes an electric unlocking mechanism 7 and a drag cable 6 .

[0053] Such as Figure 1-2 The driving mechanism is that the base plate 1 of the electric unlocking mechanism 7 has an electric unlocking mechanism mounting frame, and the base plate 1 whose driving mechanism is the drag cable 6 does not have it, thereby switching between electric and manual modes.

[0054] Such as Figure 1-2 and Figure 17-19, the substrate 1 is provided with a connector 12, the connector 12 includes a micro switch 121, when the front cover lock is in the full lock state, the micro switch 121 is in the off state, when the front cover lock is in the half lock or unlocked state, the micro switch 121 The switch 121 is in an on state.

[0055] The pawl 2 is rotatably connected to the base plate 1 through the pawl rivet shaft 13 , the ratchet 3 is rotatably connected to the base plate 1 through the ratchet rivet shaft 14 , and an upper cover 15 is provided above the ...

Abstract

The invention relates to the technical field of automobile parts, in particular to a double-pulling open-type front cover lock operation mechanism comprising a base plate. A pawl and a ratchet are rotationally connected to the base plate; a pawl spring is arranged between the pawl and the base plate; a jacking plate is connected to the ratchet; a tension spring is connected to the jacking plate; a limiting mechanism used for limiting the rotating limiting position of the pawl is arranged on the base plate; a first engaging point, a second engaging point and a third engaging point are arranged on the ratchet; the third engaging point is located between the first engaging point and the second engaging point; a first engaging part and a second engaging part are arranged on the pawl; when the first engaging part and the first engaging point are engaged, a front cover lock is in a fully-closed state; when the second engaging part and the second engaging point are engaged, the pawl is located in the first-time rotating limiting position; when the first engaging part and the third engaging point are engaged, the front cover lock is in a half-closed state; and when the pawl and the ratchet are disengaged, the front cover lock is opened. The front cover lock returns to the position after first-time pulling operation, and then second-time pulling operation can be conducted, so that stability and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a double-pull open front cover lock operating mechanism. Background technique [0002] Nowadays, people have higher and higher requirements for the improvement of the simple and comfortable operation of the hood. We have developed a double-pull opening mechanism for the outer hood lock, which can meet the requirements of regulations and people's needs for improved comfort operation, and improve the customer's ability to close and open. The comfort satisfaction of the hood. [0003] Generally, the hood lock is divided into a first-level and a second-level two-step mechanism, and it needs to be opened in two operations. The first step is to release the first-level lock of the front cover lock through the cable handle in the cab, and the second step is to open the second-level safety lock by the driver and passengers reaching into the front cover cabin by releasing the handle at...
