Description
Technical Field
The utility model relates to a car seat spare part, concretely relates to mechanism that unlocks through the stretching strap.
Background
The unlocking mechanism is applied to more automobile seats, and the existing unlocking mechanism is mainly unlocked by a stay cable, a button and a pull belt. The unlocking of the pull belt is composed of a locking plate, an unlocking pull belt, an unlocking rotating shaft, a return spring and a lock pin. The locking plate is provided with a locking notch corresponding to the lock pin, and when the locking plate is in a locking state, the lock pin is positioned in the locking notch of the locking plate, so that the rotation of the locking plate is limited; when the unlocking pulling belt is pulled, the locking plate rotates around the unlocking rotating shaft, the lock pin is separated from the locking notch of the locking plate, the unlocking pulling belt is loosened, and the locking plate automatically returns under the action of the return spring. The main problem that this structure exists is, the dynamics when pulling the stretching strap and carrying out the unblock is not good to be controlled, and is too big hard, causes the excessive compression of return spring easily to influence life.
SUMMERY OF THE UTILITY MODEL
The utility model discloses stroke control when aiming at solving the stretching strap unblock avoids exerting oneself too greatly to cause the return spring to become invalid in advance.
Therefore, the utility model discloses the technical scheme who adopts does: a pull belt unlocking mechanism for a vehicle comprises a locking plate, an unlocking pull belt, an unlocking rotating shaft, a return spring, a lock pin and a stroke limiting pin, wherein a locking notch corresponding to the lock pin is formed in the locking plate; when the locking plate is in a locking state, the lock pin is positioned in the locking notch of the locking plate, so that the rotation of the locking plate is limited, and meanwhile, the stroke limiting pin is abutted against one side wall of the limiting notch; when the unlocking pulling belt is pulled, the locking plate rotates around the unlocking rotating shaft, the lock pin is separated from the locking notch of the locking plate until the stroke limiting pin is abutted to the other side wall of the limiting notch, the unlocking pulling belt is loosened, and the locking plate automatically returns under the action of the return spring.
Preferably, a buffering vibration damping plate is clamped between the locking plate and the metal mounting plate, the metal mounting plate is provided with a middle notch, a flanging is arranged in the middle of the buffering vibration damping plate to cover the middle notch of the metal mounting plate, the flanging is narrower than the middle notch, and when the metal mounting plate is in a locking state, the lock pin penetrates through the middle notch and then penetrates through the side of the flanging and abuts against the flanging, so that the lock pin is prevented from contacting the metal mounting plate, and pre-pressure is provided for the lock pin. The flanging of the buffering vibration reduction plate provides a pre-pressure for the lock pin, so that on one hand, when the vehicle runs on a bumpy road, the buffering vibration reduction plate can prevent the lock pin from impacting the metal mounting plate to generate abnormal sound; on the other hand, when the lock pin is inserted, the lock pin is abutted to the flanging of the buffering vibration damping plate, so that the gap is eliminated, and the locking is more reliable.
The utility model has the advantages that: the structure of the locking plate and the unlocking pull belt can realize quick unlocking; the unlocking mechanism is limited in a certain stroke range by combining the stroke limiting pin and the limiting notch, the pulling belt can be prevented from being too violent in force, reliable unlocking is realized, in-place unlocking feeling is increased, operation comfort is improved, and the service life of the return spring is prolonged.
Drawings

Fig. 2 is a schematic structural diagram of the present invention (without lock cylinder).
Fig. 3 is a partially exploded view of fig. 2.
Detailed Description
The invention will be further described by way of examples with reference to the accompanying drawings:
referring to fig. 1 to 3, a vehicle pull belt unlocking mechanism mainly comprises a locking plate 1, an unlocking pull belt 2, an unlocking rotating shaft 3, a return spring 4, a lock pin 5, a stroke limit pin 6, a metal mounting plate 7 and a buffer damping plate 8.
The locking plate 1 is provided with a locking notch 1a corresponding to the lock pin 5, and the stroke limiting pin 6 is positioned in a limiting notch 1b of the locking plate 1. When in the locking state, the lock pin 5 is located in the locking notch 1a of the lock plate 1, so as to limit the rotation of the lock plate 1, and the stroke limiting pin 6 abuts against one of the side walls of the limiting notch 1 b. When the unlocking pulling belt 2 is pulled, the locking plate 1 rotates around the unlocking rotating shaft 3, the lock pin 5 is separated from the locking notch 1a of the locking plate 1 until the stroke limiting pin 6 abuts against the other side wall of the limiting notch 1b, the unlocking pulling belt 2 is loosened, and the locking plate 1 automatically returns under the action of the return spring 4. One end of the return spring 4 is hooked on the locking plate 1, and the other end is hooked on the metal mounting plate 7.
Preferably, the metal mounting plate 7 is used as a mounting plate for the lock plate 1, the unlocking rotation shaft 3, and the stroke limiting pin 6. The buffer damping plate 8 is clamped between the lock plate 1 and the metal mounting plate 7, the metal mounting plate 7 is provided with a middle gap 7a, the middle of the buffer damping plate 8 is provided with a flanging 8a, and the flanging 8a covers the middle gap 7a of the metal mounting plate 7 towards the direction of the metal mounting plate 7. The flange 8a is narrower than the central gap 7a to make less room for the passage of the locking pin. When the lock is in a locked state, the lock pin 5 passes through the middle gap 7a and then passes through the side of the flange 8a (i.e. the reserved small space) and abuts against the flange 8a, so that the lock pin is prevented from contacting the metal mounting plate 7, and pre-pressure is provided for the lock pin 5.
In addition, the unlocking drawstring 2 is preferably riveted to the locking plate 1.
