The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 10, in the embodiment, the foldable car seat assembly of the present invention includes a seat bag 100, an upper sliding sleeve 200 and a lower sliding sleeve 300 for supporting the seat bag 100, wherein the seat bag 100 is hinged to the upper sliding sleeve 200, the lower sliding sleeve 300 connects the foldable car seat assembly to a chassis of a foldable car, the upper sliding sleeve 200 is sleeved to the lower sliding sleeve 300, a sliding sleeve locking mechanism 500 is disposed at an end of the upper sliding sleeve 200 opposite to the lower sliding sleeve 300, and the sliding sleeve locking mechanism 500 is in transmission connection with a hinge shaft 400 for hinging the seat bag 100 and the upper sliding sleeve 200, so that the rotation of the seat bag 100 can drive the upper sliding sleeve 200 and the lower sliding sleeve 300 to be locked or unlocked with each other.

Under the folding car state of unfolding, seat package 100 and last sliding sleeve 200 have a certain inclination, go up sliding sleeve 200 and lower sliding sleeve 300 and overlap each other and establish and lock through sliding sleeve locking mechanism 500, when needs will folding car seat subassembly is folded, control seat package 100 and rotate 55 messenger seat package 100 and last sliding sleeve 200 and lower sliding sleeve 300 and be parallel to each other around articulated shaft 400 along anticlockwise, the rotation of articulated shaft 400 drives the sliding sleeve locking mechanism 500 action rather than the transmission is connected, sliding sleeve locking mechanism 500 is right go up sliding sleeve 200 and lower sliding sleeve 300 unblock, go up sliding sleeve 200 and lower sliding sleeve 300 this moment can carry out relative motion along its axis to reduce the shared space of folding car seat subassembly.

When the folding car seat assembly needs to be unfolded, the upper sliding sleeve 200 and the lower sliding sleeve 300 are firstly controlled to move relative to each other until the upper sliding sleeve 200 and the lower sliding sleeve move to the position where the upper sliding sleeve can be locked through the sliding sleeve locking mechanism 500, then the seat bag 100 is controlled to rotate around the hinge shaft 400 along the clockwise direction by 55 degrees, so that the seat bag 100 and the upper sliding sleeve 200 reach the angle when the seat bag is completely unfolded, the rotation of the hinge shaft 400 drives the sliding sleeve locking mechanism 500 to act, the sliding sleeve locking mechanism 500 locks the upper sliding sleeve 200 and the lower sliding sleeve 300, the upper sliding sleeve 200 and the lower sliding sleeve 300 are relatively fixed, and at the moment, the seat bag 100 is fixed again to be incapable of rotating relative to the upper sliding sleeve 200, namely, the unfolding and fixing of the folding car seat assembly are realized.

Specifically, in this embodiment, the sliding sleeve locking mechanism 500 includes locking holes disposed on the upper sliding sleeve 200 and the lower sliding sleeve 300, and a movable locking pin 503 selectively inserted into the locking holes, the movable locking pin 503 is in transmission connection with a hinge shaft 400 used for hinging the seat cover 100 and the upper sliding sleeve 200, and the rotation of the hinge shaft 400 can drive the movable locking pin 503 to be inserted into or slid out of the locking holes.

Preferably, the locking holes include a first locking hole 501 disposed on the upper sliding sleeve 200 and a second locking hole 502 disposed on the lower sliding sleeve 300, the first locking hole 501 and the second locking hole 502 have the same shape and size, and the first locking hole 501 and the second locking hole 502 can move to corresponding positions under the relative movement of the upper sliding sleeve 200 and the lower sliding sleeve 300, so that the movable locking pin 503 can simultaneously pass through the first locking hole 501 and the second locking hole 502 to lock the upper sliding sleeve 200 and the lower sliding sleeve 300.

The upper sliding sleeve 200 and the lower sliding sleeve 300 are both hollow tubular structures, and the first locking hole 501 and the second locking hole 502 respectively penetrate through the side walls of the upper sliding sleeve 200 and the lower sliding sleeve 300.

More preferably, two first locking holes 501 are symmetrically formed in the side wall of the upper sliding sleeve 200, two second locking holes 502 are symmetrically formed in the side wall of the lower sliding sleeve 300, two movable locking pins 503 are provided, and the arrangement positions of the two movable locking pins correspond to the two first locking holes 501 and the two second locking holes 502 respectively.

In the folded state of the foldable vehicle, the movable locking pin 503 penetrates through the first locking hole 501 and the second locking hole 502 at the same time, and in the folded state of the foldable vehicle, the movable locking pin 503 is withdrawn from the first locking hole 501 and is only located in the second locking hole 502. Therefore, the second lock hole 502 also serves to guide the movable lock pin 503, and the movable lock pin 503 is moved in the second lock hole 502 along the axis of the second lock hole 502.

In this embodiment, the transmission connection between the hinge shaft 400 and the sliding sleeve locking mechanism 500 is specifically as follows: the hinge shaft 400 is provided with a rotating handle 401 coaxially with the hinge shaft 400, and the sliding locking pin is in transmission connection with the position of the rotating handle 401 far away from the axis of the sliding locking pin through a connecting rod assembly 600. The connecting rod assembly 600 comprises a first connecting rod 601 and a second connecting rod 602 which are hinged to each other, the first connecting rod 601 is hinged to the movable locking pin 503, and the second connecting rod 602 is hinged to the rotating handle 401.

Under the condition that the hinge shaft 400 rotates, the rotating handle 401 drives the second connecting rod 602 to slide in the upper sliding sleeve 200 approximately along the axial direction of the upper sliding sleeve 200, the first connecting rod 601 is driven by the second connecting rod 602 to move along the axial direction of the lower sliding sleeve 300 at one end, and the movable locking pin 503 is driven by the other end to slide along the radial direction of the lower sliding sleeve 300.

An end plate 301 is arranged at one end, close to the seat bag 100, of the lower sliding sleeve 300, the sliding sleeve locking mechanism 500 and the first connecting rod 601 are arranged inside the lower sliding sleeve 300, and the second connecting rod 602 penetrates through a through hole in the end plate 301 and is hinged to the first connecting rod 601. The second connecting rod 602 is located the inside one end of lower sliding sleeve 300 is provided with the boss, the boss with the cover is equipped with spring 603 on the second connecting rod 602 between the end plate 301.

The upper sliding bush end is provided with a support 201 for supporting the seat pack 100 to be kept horizontal in the unfolded state of the folding seat assembly. A supporting rod 202 is arranged on the supporting piece 201 in parallel to the hinge shaft 400, a locking piece is arranged on the seat bag 100, and the locking piece is matched with the supporting rod 202 to selectively limit the seat bag 100 to rotate around the hinge shaft 400.

Specifically, the seat bag 100 is provided with a sliding groove 101, the locking member includes a sliding pull rod 102 and a locking tongue 103, and the locking tongue 103 is disposed in the sliding groove 101 and can pass through the sliding groove 101, and abuts against the supporting rod 202 on a side of the supporting rod 202 away from the seat bag 100.

In a state where the foldable vehicle seat assembly is unfolded, the latch 103 passes through the sliding groove 101 and abuts against the support bar 202 below the support bar 202, and at this time, in order to rotate the seat bag 100, the slide rod 102 needs to be pulled toward the rear of the foldable vehicle, so that the latch 103 is separated from the support bar 202.

In this embodiment, the bottom of the seat bag 100 is provided with a sliding groove installation assembly, the sliding groove 101 is arranged in the sliding groove installation assembly, and the sliding groove installation assembly is further provided with an automatic reset element which always applies an elastic acting force to the lock tongue 103 to move towards the supporting rod 202.
