Problems solved by technology

[0007] However, if figure 2 As shown in , each conventional coupling device has a further function in addition to the above-mentioned function of controlling the locking or unlocking between the lock and the bolt, that is, to control the window latch, the locking lever is rotated through an angle α On the basis of , the angle β must be rotated again, so there are potential problems in the operation of both coupling devices

Embodiment Construction

[0020] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] image 3 A coupling with a control latch between a lock bar and a latch member of a vehicle tailgate is shown.

[0022] Such as image 3 As shown in , in addition to the traditional components including the lock bar 3, the first link 9 and the second link 11, the coupling device also includes a window latch 21 connected to the lock part 1 through the window link 19, wherein the lock The rod 3 is coupled with one end of the first link 9 , and the latch member 7 is coupled with one end of the second link 11 .

[0023] In the above structure, there is also a control latch 23, which is connected with the other end of the first link 9 and the second link 11, so that the rotational force of the lock bar 3 caused by the window link 19 cannot be transmitted to the latch member 7 come up.

Abstract

The present invention is coupling device between lock and latch in vehicle back plate locking system. The coupling device includes latch rod with axial rotation determined by the shift of the first link rod connected to the lock; remote controlled link rod for producing axial rotation determined by the axial rotation of the latch rod to drive the second link rod; and control latch. When the lock in the locking position rotates further for any angle, the control latch allows the second link rod maintain in original position and the further rotating force will not be transmitted to the latch.

Description

technical field [0001] The present invention relates to a vehicle tailgate locking system, in particular to a rotation buffer device capable of buffering the rotation force of a lock bar, which can prevent the rotation force of the lock bar from being transmitted to the latch of the tailgate in the vehicle locking system. Background technique [0002] In the coupling between the tailgate lock and latch, both components of the vehicle's tailgate locking system, the tailgate lock and latch are directly connected by a single link connection, or through two connecting rods connected by an intermediate crank. [0003] Because the lock bar will turn right or left an appropriate angle, the tailgate lock will lock or unlock the tailgate latch through the link between them. [0004] figure 1 Shown are conventional couplings, i.e., a coupling between the lock bar and the latch part via a single link, and alternatively, a link between the lock bar and the latch part via two links and...
