The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

In the following description, the directions involved, such as "front", "rear", "left", "right", "up", and "down", are all based on the installation of the child safety seat on the car seat, with the front direction of the car as the front, the rear direction as the rear, the top direction as the top, the bottom direction as the bottom, and the left and right sides of the car as the left and right directions. The definitions of the above directions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

As shown in FIG. 1 , the child safety seat of the present invention comprises a base 1 and a seat shell 2 arranged on the base 1 .

The seat shell 2 is rotatably disposed on the base 1 via a first axis 6 extending in the up-down direction. The seat shell 2 can rotate relative to the base 1 around the first axis 6, so that the child safety seat has at least a forward use state and a reverse use state.

When the child safety seat is in the forward use state, the child sits in the child safety seat with the child's face facing forward, as shown in Figure 1. When the child safety seat is in the reverse use state, the child sits in the child safety seat with the child's face facing backward. The seat shell 2 rotates relative to the base 1 around the first axis 6, so that the child safety seat can be switched between the forward use state and the reverse use state.

The child safety seat also includes a locking mechanism, through which the relative positions of the base 1 and the seat shell 2 are locked. The locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the seat shell 2 cannot rotate relative to the base 1. When the locking mechanism is in the unlocked state, the seat shell 2 can rotate relative to the base 1. When the child safety seat is in the forward use state and the reverse use state, the locking mechanism is in the locked state. When the child safety seat needs to be switched between the forward use state and the reverse use state, the locking mechanism is in the unlocked state.

As shown in Figs. 2 to 7 and 12, the locking mechanism includes a locking member 3 and a locking portion 21 matched with the locking member 3, the locking member 3 is rotatably arranged on one of the base 1 and the seat shell 2 around the second axis 7, and the locking portion 21 is arranged on the other of the base 1 and the seat shell 2. When the locking mechanism is in a locked state, the locking member 3 cooperates with the locking portion 21, so that the seat shell 2 and the base 1 are relatively fixed, as shown in Figs. 4 and 5. When the locking mechanism is in an unlocked state, the locking member 3 is disengaged from the locking portion 21, as shown in Figs. 6 and 7.

Specifically, the locking member 3 includes a main body 31 and a locking tongue 32 disposed on the main body 31, the locking portion 21 is a locking groove, and the locking tongue 32 is adapted to the locking groove. When the locking mechanism is in a locked state, the locking tongue 32 is inserted into the locking groove, as shown in Figures 4 and 5. When the locking mechanism is in an unlocked state, the locking tongue 32 is disengaged from the locking groove, as shown in Figures 6 and 7.

The child safety seat also includes an unlocking mechanism. When the locking mechanism is in a locked state, the unlocking mechanism is operated to unlock the locking mechanism, thereby rotating the seat shell 2 relative to the base 1, so that the child safety seat is switched between a forward use state and a reverse use state.

As shown in FIGS. 8 to 12 , the unlocking mechanism includes an unlocking button 41, a driving member 42 and a connecting member 43. The unlocking button 41 can be slidably arranged on a part of the base 1 and the seat shell 2 on which the locking member 3 is arranged. The driving member 42 is rotationally connected to the unlocking button 41 via a third shaft 44, and the driving member 42 cooperates with the parts of the base 1 and the seat shell 2 on which the locking member 3 is arranged. One end of the connecting member 43 is connected to the driving member 42, and the other end of the connecting member 43 is connected to the locking member 3.

When the locking mechanism is in a locked state and the unlocking button 41 is pressed, the unlocking button 41 slides relative to the parts of the base 1 and the seat shell 2 on which the locking member 3 is arranged, driving the driving member 42 to synchronously slide relative to the parts of the base 1 and the seat shell 2 on which the locking member 3 is arranged. When the driving member 42 slides, the driving member 42 cooperates with the parts of the base 1 and the seat shell 2 on which the locking member 3 is arranged, so that the driving member 42 rotates relative to the unlocking button 41 around the third axis 44. When the driving member 42 rotates, the locking member 3 is pulled by the connecting member 43, thereby causing the locking member 3 to rotate, causing the lock tongue 32 to disengage from the lock groove, and the locking mechanism is unlocked.

In this embodiment, the driving member 42 cooperates with the parts of the base 1 and the seat shell 2 on which the locking member 3 is provided as follows: a convex portion 11 is provided on the parts of the base 1 and the seat shell 2 on which the locking member 3 is provided, and a slope 421 is provided on the driving member 42, and the convex portion 11 abuts against the slope 421. When the driving member 42 slides under the drive of the unlocking button 41, the driving member 42 rotates relative to the unlocking button 41 around the third axis 44 due to the abutment of the convex portion 11 against the slope 421.

In this embodiment, the connecting member 43 is a rigid connecting member, and the connecting member 43 can be slidably arranged on the parts of the base 1 and the seat shell 2 where the locking member 3 is arranged. One end of the connecting member 43 is rotatably connected to the driving member 42, and the other end of the connecting member 43 is rotatably connected to the locking member 3. When the driving member 42 rotates relative to the unlocking button 41 around the third axis 44, the driving member 42 rotates relative to the connecting member 43, and the connecting member 43 is pulled to slide relative to the parts of the base 1 and the seat shell 2 where the locking member 3 is arranged, so that the connecting member 43 and the locking member 3 rotate relative to each other, and the locking member 3 is driven to rotate around the second axis 7, so that the locking mechanism is unlocked.

Of course, the connecting member 43 may also be a flexible connecting member. In this case, one end of the connecting member 43 is fixedly disposed on the driving member 42 , and the other end of the connecting member 43 is fixedly disposed on the locking member 3 .

In this embodiment, the locking member 3 is rotatably arranged at the front of the base 1, the base 1 has a cavity, and the upper part of the base 1 is also provided with a slot 12 that connects the cavity with the outside, the locking member 3 is rotatably arranged in the cavity of the base 1, the second shaft 7 extends in the left and right directions, and the locking slots are respectively arranged at the opposite ends of the seat shell 2. When the locking mechanism is in a locked state, the locking tongue 32 extends from the slot 12 to the outside of the base 1, when the child safety seat is in a forward use state, the locking tongue 32 is clamped into one locking slot, and when the child safety seat is in a reverse use state, the locking tongue 32 is clamped into another locking slot. When the locking mechanism is in an unlocked state, the locking tongue 32 retracts into the cavity of the base 1.

The unlocking mechanism is respectively arranged on the left and right sides of the front part of the base 1. Specifically, the main body 31 of the locking member 3 extends in the left-right direction, the locking tongue 32 is arranged in the middle of the main body 31, and the connecting members 43 on the left and right sides are respectively connected to the corresponding ends of the main body 31. When the unlocking mechanism is operated on either side of the left or right side, the locking member 3 can be driven to rotate relative to the base 1 through the connecting member 43, so that the locking mechanism is unlocked, which facilitates the unlocking operation of the child safety seat.

The child safety seat further comprises an elastic member 5, the elastic force of which is used to drive the locking mechanism to automatically reset from the unlocked state to the locked state. In this embodiment, the elastic member 5 is a tension spring, one end of which is arranged on the base 1, and the other end of which is arranged on the locking member 3.

When the child safety seat is in the forward use state, the locking mechanism is in a locked state, that is, the locking tongue 32 of the locking member 3 extends out of the cavity of the base 1 and is locked in a locking groove.

When the child safety seat needs to be switched to the reverse use state, the unlocking button 41 is pressed to slide downward relative to the base 1, so that the driving member 42 slides downward synchronously. In this process, due to the abutment of the convex portion 11 and the inclined surface 421, the driving member 42 rotates relative to the unlocking button 41 around the third axis 44 at the same time, so that the connecting member 43 moves forward. When the connecting member 43 moves forward, it pulls the locking member 3, so that the locking member 3 rotates around the second axis 7, so that the locking tongue 32 escapes from the current locking groove and retracts into the cavity of the base 1, and the locking mechanism is unlocked. The seat shell 2 rotates relative to the base 1 around the first axis 6. When the seat shell 2 rotates to the position where another locking groove on it corresponds to the slot 12 on the base 1, the locking member 3 rotates in the reverse direction under the elastic force of the elastic member 5, and the locking tongue 32 extends from the slot 12 on the base 1 and is inserted into another locking groove. The locking mechanism is locked again, and the child safety seat is in the reverse use state.

The method for switching the child safety seat from the reverse use state to the forward use state is the same as above and will not be repeated here.

The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
