Detailed ways

The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments: the utility model has no special statement, the left side in Fig. 4 is the front end of the utility model, and the right side in Fig. 4 is the rear of the utility model End, the upper end in Fig. 4 is the upper end of the utility model, and the lower end in Fig. 4 is the lower end of the utility model.

Referring to Figures 1 to 18, a child safety seat for a vehicle includes a base 1, the base 1 is hinged to a seat back 3 through a hinge 2, and the end of the hinge 2 located outside the seat back 3 is provided with an external thread. A knob 4 is screwed on the external thread. When the chair back 3 needs to be rotated, the knob 4 is loosened, and the chair back 3 can be rotated relative to the base 1 with the hinge 2 as the axis of rotation.

The base 1 is provided with a first groove 10, the back of the chair back 3 is provided with a first plate 17, and the upper end of the first plate 17 has a receiving portion 21, and the first plate 17 is combined with a first plate 17. The second board 19 , the first sliding member 7 passes through between the first board 17 and the second board 19 . The upper end of the first sliding member 7 is provided with a first annular protrusion 70 , and a first elastic component 9 is sleeved on the first annular protrusion 70 . When no force is applied, the upper end of the first elastic component 9 abuts against the bottom of the accommodating portion 21 , and the lower end of the first elastic component 9 abuts against the upper end of the first sliding member 7 . Preferably, the first elastic component 9 is a spring.

Preferably, the lower end of the first sliding member 7 has an arc-shaped surface 72 . The arc surface 72 is provided so that the first sliding member 7 can slide over the base 1 smoothly, and the first sliding member 7 can be snapped into the first groove 10 .

The receiving portion 21 at the upper end of the first plate 17 is provided with a second groove 210 , the receiving portion 21 has an elastic piece 211 on the side wall corresponding to the second groove 210 , and the elastic piece 211 has a first protrusion 212 , the elastic piece 211 is also provided with a protruding piece 213 which is convenient for holding.

The lower end of a headrest 5 is provided with a connecting plate 6 , the connecting plate 6 passes through the second groove 210 , and the connecting plate 6 is provided with a second protrusion 60 . The upper end of the first protrusion 212 has a tapered surface 2120 . The function of the tapered surface 2120 is to facilitate the sliding of the first protrusion 212 over the second protrusion 60 .

The headrest 5 described above includes a body 50, and guard plates 51 are arranged on both sides of the body 50, and a side wall of the guard plate 51 is arranged between the guard plate 51 and the body 50 so that the side wall of the guard plate 51 can be folded on the side wall of the body 50. the folding mechanism.

The folding mechanism includes a hinge mechanism arranged between the body 50 and the guard plate 51 , and a third slot 52 arranged on the guard plate 51 , and the body 50 is provided with a first sliding groove relative to the body 50 . Two sliding parts 11, the end of the second sliding part 11 has an arc surface 110.

The body 50 is provided with a second annular protrusion 500 , and a second elastic component 13 is sleeved on the second annular protrusion 500 . One end of the second sliding member 11 leans against the second elastic component 13 . Preferably, the second elastic component 13 is a spring.

When the headrest 5 is installed on the seat back 3, the connecting plate 6 is inserted into the second groove 210, and the second protrusion 60 provided on the connecting plate 6 contacts the first protrusion 212, and the first protrusion 212 Under the action of the tapered surface 2120 , the elastic sheet 211 is stretched toward the back of the seat back 3 , and finally the second protrusion 60 slides over the first protrusion 212 . Thus, the headrest 5 is mounted on the seat back 3 .

When it is necessary to separate the headrest 5 from the seat back 3, lift the headrest 5 upwards, and when the second protrusion 60 is close to the first protrusion 212 (due to the blocking effect of the first protrusion 212, the second protrusion 60 cannot slide through the first protrusion 212, which not only makes the product safer, but also effectively prevents misuse, that is, the headrest 5 is accidentally pulled out of the seat back 3, which will affect the use of the product.), pull the tab 213, In this way, the elastic sheet 211 is stretched toward the back of the seat back 3, so that the first protrusion 212 no longer blocks the second protrusion 60, so that the connecting plate 6 of the headrest 5 slides out of the receiving portion 21, thereby realizing the headrest 5 Separation from the chair back 3.

When it needs to be transported, first remove the headrest 5 from the seat back, and then fold the seat back 3 on the base 1, the operation method is as follows: lift the first sliding part 7, and make the lower end of the first sliding part 7 leave the first slot 10 (see Figure 5), and then the seat back 3 is rotated counterclockwise with the hinge 2 as the rotation axis and the base 1, and finally folded to the state shown in Figure 3 . Then fold the side wall of the guard plate 51 on the headrest 5 onto the side wall of the main body 50, the operation method is as follows: pull the second sliding part 11 to make the end of the second sliding part 11 leave the third groove 52 (see Figure 10) , and then fold the side wall of the guard plate 51 on the side wall of the body 50 (see Figure 11 and Figure 12). Afterwards, the folded headrest 5 is stuffed between the folded seat back and the base.

When it needs to be used, first open the seat back 3, the operation method is as follows, forcefully lift the seat back 3, so that the seat back 3 rotates clockwise with the hinge 2 as the axis of rotation and the base 1, and the arc surface of the first sliding member 7 slides Pass through the base 1 and snap into the first groove 10 under the action of the first elastic component 9 . Thereby realizing that the seat back 3 is in a normal use state. Then open the headrest 5, the operation method is as follows, turn the guard plate 51, make the arc-shaped surface 110 of the second sliding member 11 slide over the body 50, and snap into the third groove 52 under the action of the second elastic component 13, thereby Make head restraint 5 be in normal use condition.
