The backrest latch according to the first aspect of the present invention will be described first in detail with reference to the drawings.
As shown in fig. 1, the backrest latch according to the first aspect of the present invention includes a first bracket 1, a latch portion, a second bracket 2, and a pull rope assembly. An accommodating cavity is formed in the first bracket 1, and the first bracket 1 is used for being fixed at the upper end of the backrest of the automobile seat; one end of the lock pin part is pivotally connected in the accommodating cavity between a first position and a second position, when the lock pin part is at the first position, the other end of the lock pin part protrudes out of the first bracket 1, and when the lock pin part is at the second position, the other end of the lock pin part is retracted into the first bracket 1; the second bracket 2 is used for being fixed at the lower end of the backrest; one end of the traction rope assembly is connected to the lock pin portion, the other end of the traction rope assembly is connected to the second support 2, and when the traction rope assembly is in a tightening state, the traction rope assembly pulls the lock pin portion to rotate.
The backrest latch of the utility model is normally arranged between two side-by-side backrests, which are provided as a first backrest 3 and a second backrest 4, the first bracket 1 being arranged at the upper end of the first backrest 3 and the second bracket 2 being arranged at the lower end of the second backrest 4, the second bracket 2 being able to rotate with the second backrest 4. A traction rope component is arranged between the two brackets, one end of the traction rope component is connected to the second bracket 2 which can rotate along with the backrest, and the other end of the traction rope component is connected to the rotatable locking pin. Therefore, in the process of putting down the backrest, the second bracket 2 rotates along with the backrest and stretches the traction rope assembly, when the traction rope assembly is stretched to a certain degree, the traction rope assembly can be tightened, then the traction rope assembly can drive the lock pin to rotate, and when the backrest is completely put down, the lock pin is also retracted into the first bracket 1 through rotation. The backrest latch can retract the protruding lock pin when the backrest is laid down, so that personal safety is guaranteed, and attractiveness is improved.
Further, as shown in fig. 2, the locking pin portion includes a T-shaped locking pin 5, a runner 6, and a return spring 7. The rotating wheel 6 is pivotally connected to one side of the accommodating cavity, one end of a transverse shaft of the T-shaped lock pin 5 is connected to the axis of the rotating wheel 6, and one end of the traction rope assembly is connected to the rotating wheel 6 so as to pull the rotating wheel 6 and the T-shaped lock pin 5 to rotate; one end of the return spring 7 is connected to the other end of the transverse shaft of the T-shaped lock pin 5, the other end of the return spring 7 is connected to the other side of the containing cavity, and when the return spring 7 is not deformed, the T-shaped lock pin 5 is located at the first position.
The lock pin is arranged in a T shape, a transverse shaft of the T-shaped lock pin 5 is connected in the first support 1 through a rotating wheel 6 and a return spring 7, when the backrest does not rotate, the return spring 7 maintains a vertical shaft of the T-shaped lock pin 5 at a position which is vertical and protrudes out of the first support 1, and in the rotation process of the backrest, the traction rope component drives the rotating wheel 6 to rotate to a position which is parallel to and retracted into the first support 1 in a clockwise or anticlockwise direction; during the lifting process of the backrest, the return spring 7 drives the lock pin to rotate to a position which is vertical and protrudes out of the first bracket 1 according to the anticlockwise direction or the clockwise direction. The structure is easy to manufacture and simple and convenient to operate.
Further, as shown in fig. 1, the pulling rope assembly comprises a compensator 8, a first pulling rope 9 and a second pulling rope 10. The one end of first haulage rope 9 is connected in runner 6, and the other end of first haulage rope 9 is connected in compensator 8, and the one end of second haulage rope 10 is connected in second support 2, and the other end of second haulage rope 10 is connected in compensator 8, and after second haulage rope 10 was stretched to predetermineeing the distance, the haulage rope subassembly was in the state of tightening.
As shown in fig. 3, the second backrest 4 is provided with a locking mechanism 11 corresponding to the locking pin portion, and the locking pin portion and the locking mechanism 11 cooperate with each other to lock or unlock the two backrests. If the lock pin portion follows the rotation of the backrest as soon as the backrest starts to rotate after the lock pin portion is opened from the lock mechanism 11, a protruding portion of the lock pin portion may hit the lock mechanism 11 or be caught by the lock mechanism 11 because the lock pin portion is located close to the lock mechanism 11. After the compensator 8 is arranged, when the backrest starts to rotate, the compensator 8 can absorb the tension of the second traction rope 10, and the second traction rope 10 can not drive the first traction rope 9 to move; when the second hauling cable 10 is stretched to a certain distance, the compensator 8 can not continuously absorb the pulling force of the second hauling cable 10, the hauling cable assembly is in a tight state, and the second hauling cable 10 starts to drive the first hauling cable 9 and the rotating wheel 6 to move. Therefore, the compensator 8 can be arranged to realize that the lock pin starts to move after the backrest rotates for a certain angle, and the collision of the lock pin and the locking mechanism 11 is avoided.
Further, when the second bracket 2 is rotated to a preset angle, the second traction rope 10 is stretched to a preset distance, preferably, the preset angle is 20-30 °.
Further, as shown in fig. 4, the second bracket 2 includes:
a body bracket 12, wherein the body bracket 12 is fixed at the lower end of the backrest;
the haulage rope support 13, haulage rope support 13 are fixed on the drive support, and the other end of haulage rope subassembly is connected on haulage rope support 13.
