Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 3, a backrest lock mechanism 100 according to an embodiment of the present invention includes: a lock member 10 and a lock body 20, wherein one of the lock member 10 and the lock body 20 is mounted on a seat back 200 (such as a rear seat back) and the other is mounted on a back panel of a vehicle, preferably, the lock body 20 may be mounted on the seat back 200 and the lock member 10 may be mounted on the back panel of the vehicle.

The locking member 10 includes an integral locking hook 17 and an upper pulling strap fixing portion 16, the upper pulling strap fixing portion 16 is adapted to be connected to an upper pulling strap 202 of the child seat, and the lock body 20 is selectively lockable with the locking hook 17. It can be understood that, because the latch hook 17 and the upper pull belt fixing portion 16 are integrally designed, the latch hook 17 and the upper pull belt fixing portion 16 can be reinforced at the same time only by designing a reinforcing structure at one position.

According to the backrest locking mechanism 100 provided by the embodiment of the invention, the functions of fixing the upper pull belt 202 of the child seat and locking the seat are integrated, an additional structure-reinforced design is not required, the research and development progress of the whole vehicle can be effectively accelerated, the production cost is reduced, and the lightweight level of the whole vehicle is favorably improved.

In some preferred embodiments of the present invention, as shown in fig. 2 and 3, the shackle 17 is in the form of a vertical bar and the lock body 20 is arranged laterally.

Thus, when the ADR 34/01 certification test is performed on the vehicle, the latch hook 17 is locked with the latch body 20, the pull-up strap 202 of the child seat is hooked on the fixed point of the pull-up strap 202, and a pull force of a predetermined magnitude (3400N) in the-X direction is applied to the pull-up strap 202.

In the process of tension loading, the framework 201 of the seat back 200 bends forwards (-X direction) and drives the lock body 20 to bend together, and because the lock body 20 is transversely arranged, the rotation trend of the lock body 20 is blocked by the vertical lock hook 17 and cannot rotate, the vertical lock hook 17 is still kept at the original position, that is, the lock body 20 and the lock hook 17 cannot slip, so that the successful loading of the hydraulic machine in the ADR 34/01 regulation certification test can be ensured.

Correspondingly, in the related art, the lock hooks are transversely arranged, the lock bodies are longitudinally arranged, in the tension loading process, the framework of the seat back is bent forwards (-X direction) and drives the lock bodies to be bent together, the lock bodies rotate around the transverse lock hooks, the transverse lock hooks easily slide to the interface parts of the locking openings of the lock bodies, the structural strength of the interface parts is weak, the surfaces of the lock hooks are smooth, the lock bodies easily slip out of the lock bodies under the action of tension, finally, the loading load of the hydraulic machine for the ADR 34/01 regulation certification test fails, and the performance of the vehicle type cannot meet the regulation requirements.

Specifically, as shown in fig. 2, the lock body 20 includes: fixed plate 21, bolt 22, driving plate 23, pull wire 24 and switch 25.

Wherein, the fixing plate 21 is suitable for being installed on the framework 201 of the seat back 200, for example, the fixing plate 21 can be installed on an installation plate through a threaded fastener, the installation plate is suitable for being installed on the framework 201 of the seat back 200, a hook-shaped locking head of the fixing plate 21 can be arranged on the fixing plate 21, the locking tongue 22 can be rotatably installed on the fixing plate 21, and a locking ring that is closed may be selectively defined between the locking tongue 22 and the fixed plate 21, as shown in fig. 2, the locking tongue 22 may have a locking groove that is selectively closed by a locking head of the fixed plate 21 and forms the locking ring when closed, a driving plate 23 is rotatably installed on the fixed plate 21, and the driving plate 23 is connected with the locking tongue 22, the pulling wire 24 is connected with the driving plate 23, the switch 25 is connected with the pulling wire 24, when the switch 25 is pulled, the pull wire 24 drives the transmission plate 23 to rotate, the bolt 22 rotates along with the transmission plate, and the lock ring is opened, so that unlocking is realized.

Further, because the lock body 20 is transversely arranged, the stay wire 24 can be L-shaped, and compared with the S-shaped stay wires in the related art, the stay wire 24 of the embodiment of the invention has shorter length, and can reduce the cost.

In some preferred embodiments of the present invention, the lock member 10 can be formed by bending a metal rod, so that the backrest lock mechanism 100 is suitable for mass production and is low in manufacturing cost.

Specifically, referring to fig. 3, the lock member 10 includes a first connecting section 11, a second connecting section 15, a first section 12, a second section 13, and a third section 14.

The first section 12, the second section 13 and the third section 14 are connected in sequence, the first section 12 can extend along the left-right direction, the second section 13 extends along the front-back direction, the third section 14 extends along the up-down direction, the first section 12 forms an upper pull strip fixing part 16, and the third section 14 forms a lock hook 17. The left-right direction, the front-back direction, and the up-down direction described herein are not limited to the right-left direction, the front-back direction, and the up-down direction, and may be a slightly oblique direction.

Specifically, the first section 12 is perpendicular to the second section 13, the second section 13 is perpendicular to the third section 14, the first section 12 may extend in the-Y direction from an end away from the second section 13 to an end connected to the second section 13, the second section 13 may extend in the-X direction from an end connected to the first section 12 to an end connected to the third section 14, and the third section 14 may extend in the-Z direction from an end connected to the second section 13 to the other end.

The first connecting section 11 is connected with one end of the first section 12 far away from the second section 13, and the first connecting section 11 extends in the front-back direction towards the direction far away from the second section 13, specifically, the first connecting section 11 can be perpendicular to the first section 12, and the first connecting section 11 extends in the-X direction from one end far away from the first section 12 to one end connected with the first section 12.

The second connecting section 15 is connected to one end of the third section 14 far away from the second section 13, and the second connecting section 15 extends in the front-back direction toward the direction close to the second section 13, specifically, the second connecting section 15 may be perpendicular to the third section 14, and the second connecting section 15 extends in the X direction from one end far away from the third section 14 to the other end.

The free end of the first connecting section 11 and the free end of the second connecting section 15 are flush, and the free end of the first connecting section 11 and the free end of the second connecting section 15 can be used for being connected with a back panel in a welding mode, so that the locking piece 10 can be fixedly installed.
