Detailed ways

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 7, the child safety seat of the present invention includes a base 1 and a seat body, the seat body and the base 1 are rotationally connected around an axis 2, and the axis 2 extends along the up and down direction.

The seat body includes a seat shell 3 and a turntable 4 , the seat shell 3 is fixedly arranged on the turntable 4 , and the turntable 4 is rotatably connected with the base 1 around the axis 2 .

The seat shell 3 includes a seat part 31 and a backrest part 32. The turntable 4 can drive the seat shell 3 to rotate in a horizontal plane relative to the base 1 around the axis 2, so that the child safety seat has a positive use state and a reverse direction. to use status.

When the child safety seat is in the forward use state, the seat part 31 is positioned at the front of the backrest part 32. At this moment, the child safety seat can be used by children who are slightly older and can sit and stand independently. When the child safety seat is in the reverse use state, the seat part 31 is positioned at the rear of the backrest part 32, and the child safety seat is used for lying down on the child safety seat at this moment.

The locking mechanism can lock the relative positions of the base 1 and the seat body, so that the child safety seat is locked in the forward use state and the reverse use state respectively. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the relative positions of the base 1 and the seat body are fixed, and the two cannot rotate relative to each other. When the locking mechanism is in an unlocked state, the seat body can rotate relative to the base 1, thereby adjusting the use state of the child safety seat.

When the base 1 or the seat body moves, the locking member 5 can slide relative to the base 1 or the seat body, thereby unlocking the locking mechanism.

Specifically, one of the two parts of the locking part 5 and the unlocking part 7 is provided with a first matching part 52, and the other part is respectively provided with a second matching part 71 and a third matching part 72. The second matching part 71 Both the third matching portion 72 and the first matching portion 52 can be matched.

When the unlocking part 7 is driven to move to the left, the first matching part 52 is matched with the second matching part 71, and through the cooperation between the two, the locking part 5 can be made to disengage from the locking part 51 from the lock groove 411. direction to unlock the locking mechanism, as shown in Figure 4 and Figure 7.

When the unlocking part 7 is driven to move to the right, the first matching part 52 is matched with the third matching part 72, and through the cooperation between the two, the locking part 5 can also be made to disengage the locking part 51 from the locking groove 411. slide in the direction to unlock the locking mechanism, as shown in Figure 4, Figure 5 and Figure 7.

In this way, when the locking mechanism is in the locked state, whether the unlocking member 7 is driven to move left or right, the locking mechanism can be unlocked, which is convenient for adults to operate the unlocking member 7 according to their own position, so that the locking mechanism unlock.

The left and right sides of the unlocking member 7 are respectively provided with operating parts 73 for manual operation when unlocking the locking mechanism. In this embodiment, the operating part 73 is for people to push when unlocking the locking mechanism. Of course, it is also possible to unlock the locking mechanism by pulling the operation portion 73 . When the locking mechanism is unlocked, when the operating portion 73 on either side of the unlocking member 7 is operated to move the unlocking member 7, the operating portion 73 on the other side can be operated synchronously.

In this embodiment, the first matching portion 52 is a fixed column, the second matching portion 71 is a first chute matching with the fixing column, and the third matching portion 73 is a second chute matching with the fixing column The length extension direction of the first chute and the second chute is inclined relative to the sliding direction of the locking member 5, and the inclination direction of the first chute and the second chute is opposite, preferably the first chute and the second chute The grooves are arranged symmetrically, and the fixing column is arranged so as to be slidable along the extending direction of the length of the first sliding groove or the second sliding groove.

One end of the first chute is connected to the second chute, and the other end of the first chute is far away from the second chute, so that the first chute and the second chute form a V-shaped structure. When the locking mechanism is in the locked state, the fixing post is located at one end where the first slide slot and the second slide slot are connected, that is, at the apex of the V-shaped structure, as shown in FIG. 2 , FIG. 3 and FIG. 6 . When the locking mechanism is in the unlocked state, the fixing column is located at the other end of the first sliding groove, or the fixing column is located at the other end of the second sliding groove, as shown in Fig. 4 , Fig. 5 and Fig. 7 .

In this embodiment, the first fitting part 52 is arranged on the locking part 5, the second fitting part 71 and the third fitting part 72 are both arranged on the unlocking part 7, and the locking part 51 and the first fitting part 52 are respectively located on the locking part 5. Both ends in the sliding direction.

In this embodiment, the lock groove 411 is arranged on the seat body, specifically on the turntable 4, the base 1 is provided with a cylindrical part 11, the turntable 4 is provided with a ring part 41 matching with the cylindrical part 11, and a plurality of locks The grooves 411 are arranged on the ring portion 41 at intervals along the circumferential direction of the ring portion 41 . Preferably, there are two lock slots 411, and the two lock slots 411 are arranged at intervals of 180 degrees, as shown in FIG. 3 and FIG. 5 .

The locking member 5 is provided on the base 1 so as to be slidable in the front-rear direction. When the unlocking member 7 is operated to unlock the locking mechanism, the locking member 5 slides forward relative to the base 1 . The elastic force of the elastic member 6 drives the locking member 5 to slide backward relative to the base 1 .

The unlocking member 7 is rotatably or slidably arranged on the base 1 . Specifically, the base 1 is provided with a guide groove, which is arc-shaped, and runs through the left and right sides of the base 1 . The unlocking part 7 matches the arc structure of the guide groove, that is, the unlocking part 7 also has an arc structure, and the unlocking part 7 can be movably arranged in the guide groove along the length extension direction of the guide groove. When the locking mechanism is in the locked state, the outer surfaces of the operating parts 73 on the left and right sides of the unlocking member 7 are flush with the side surfaces of the base 1 on the corresponding side, so that the appearance of the child safety seat is neat and beautiful, as shown in Figure 1 and shown in Figure 6.

The above definition of direction refers to the direction of an adult when he is riding in the car. The direction of the adult's face is the front, the direction of the back is the rear, and the left and right sides of the adult's body are the left and right directions of this embodiment.
