Referring to fig. 1-3, a vehicle seat back unlock indicator 100 is typically mounted on the back top and near the sides of a rear seat of a vehicle, and is at least partially wrapped inside the seat back and therefore is typically not visible from the outside of the back.
The vehicle seat back unlocking indicator 100 mainly includes a lock case 101, a reminder plate 102 movably installed in an upper space of the lock case 101, and a clip lock device 1 pivotably installed in a lower space of the lock case 101. Correspondingly, a catch 104 is fastened to the frame of the vehicle so that the clip lock device 1 can be locked into the catch, for example, the catch is arranged on the frame of the side or rear of the rear seat.
The pinch lock device 1 is configured to allow the reminder plate 102 to protrude outside the lock case 101 when the pinch lock device 1 is in an unlocked position and to allow the reminder plate 102 to retract inside the lock case 101 when the pinch lock device 1 is in a locked position.
The clip lock device 1 mainly includes:
An actuating element 10 comprising a push rod 11 for driving a tip plate link 103, said tip plate link 103 for driving said tip plate 102 to protrude outside said lock housing 101, and a torsion spring 12 for letting said push rod 11 obtain a biasing force in the direction of said tip plate link 103; and
A shackle element 20 comprising a positioning hole 21 for pivotally mounting said shackle element 20 within said lock housing 101, and a locking tongue 22 extending distally of said positioning hole 21.
As shown in fig. 2, when the pinch lock device 1 is in the locked position, the locking tongue 22 enters the shackle 104, in which the push rod 11 of the actuating member 10 is remote from the tip plate link 103.
As shown in fig. 3, when the clip lock device 1 is in the unlocked position, the lock tongue 22 is disengaged from the lock catch 104, and in the unlocked position, the push rod 11 of the actuating element 10 applies a pushing force to the tip plate link 103.
Referring to fig. 4, the latch hook member 20 includes:
A metallic shackle body 23, in which a through hole, also called a locating hole 21, is provided in the middle, and
-A cladding housing 24 overmolded around the periphery of the metallic shackle body, comprising:
-a cable mounting opening 27 provided in a downstream direction of the positioning hole 21, the cable mounting opening 27 being for connection to an unlocking cable (not shown), the locking hook member 20 being pivotable about the positioning hole 21 to disengage the locking bolt 22 from the shackle 104 when the cable mounting opening is pulled by the unlocking cable, wherein the positioning hole is located between the locking bolt 22 and the cable mounting opening 27; and
A fixed post 25, provided in the upstream direction of the positioning hole 21, more specifically in the vicinity of the root 220 of the tongue 22, for fitting the actuating element 10.
The fixing posts 25 extend perpendicularly to the lateral surface 240 of the covering shell 24 and have, at their free ends, ribs 26 preventing the actuating element 10 from falling out.
In the embodiment shown, the fixing studs 25 of the cladding shell 24 are constituted by four quarter-cylinders and are separated from each other by a gap, so that they obtain a deformation space, which gives the fixing studs their elasticity. The free end of each quarter-cylinder has a flange that prevents the actuating element 10 from falling out.
In a variant, the fixing studs 25 of the cladding shell 24 are constituted by two half cylinders and are separated from each other by a gap. The free end of each half cylinder has a flange that prevents the actuating element 10 from falling out.
The cover housing 24 also has a bayonet 28 for receiving the free end of the torsion spring 12 of the actuating element 10 so that the torsion spring 12 obtains a resilient force when the actuating element 10 rotates, thereby ensuring that the push rod 11 of the actuating element 10 abuts the tip plate link 103 when pushing the tip plate link 103.
Optionally, the cover shell 24 may also be provided with ribs or grooves.
Referring to fig. 5, the actuating element 10 further comprises a sleeve 13 adapted to be inserted into the fixing leg 25 of the latch hook element 20, a first arm 17 for pushing the reminder plate link 103 in the unlocked position and a second arm 18 for abutting against the shackle 104 in the locked position extending on both sides of the sleeve 13 in a radial direction of the sleeve 13, respectively, wherein the push rod 11 extends at a free end of the first arm 17 in an axial direction parallel to the sleeve 13.
The torsion spring 12 is wound around the sleeve 13, the first free end 121 of the torsion spring 12 being adapted to snap into a recess 171 below the first arm 17 to provide upward traction thereto, and the second free end 122 of the torsion spring 12 being adapted to be inserted into the bayonet 28 of the covering housing 24.
The sleeve 13 has an elongated notch 14 in its axial direction, which notch 14 allows the sleeve 13 to be deformed to a certain extent so that it can be slipped into the fixing post 25 of the cladding shell 24 through the flange 26 of the fixing post 25, so that the connection between the sleeve 13 and the fixing post 25 can be called an "elastic collet" without requiring any additional connecting piece, avoiding the complex process of riveting and welding commonly used in the prior art.
In fig. 5, the number of notches 14 is four, but the number of notches is not limited to four, and may be two or other.
More specifically, the sleeve 13 of the actuating element 10 has a free end flange 15 and a root flange 16 extending in the radial direction of the sleeve at both ends of the axial direction of the sleeve, the free end flange 15 and the root flange 16 defining the torsion spring 12 therebetween.
When the clamp lock device is assembled, the assembly can be completed in a simple few steps:
First, the torsion spring 12 is sleeved into the sleeve 13 of the actuating element 10, and the first free end 121 of the torsion spring 12 is buckled at the retraction notch 171 below the first arm 17; and
In a second step, the actuating element 10 with the torsion spring 12 is fitted through the sleeve 13 into the fixing leg 25 of the covering housing 24 of the locking hook element 20, and the second free end 122 of the torsion spring 12 is inserted into the bayonet 28 of the covering housing 24.
If the clip lock device is to be further mounted into the vehicle seat back unlocking indicator, the positioning hole 21 of the latch hook element 20 of the clip lock device is simply put into the corresponding mounting position in the vehicle seat back unlocking indicator and fixed with a rivet or bolt.
The clamping and locking device has the advantages of simple structure, convenience in assembly, low cost and no need of additional riveting, and can further improve the assembly efficiency.
