[0025] like Figure 1 As shown, the child safety seat comprises a base 1 , a connecting member 2 arranged on the base 1 , and a seat shell 3 arranged on the connecting member 2 .
[0026] The seat shell 3 can be slidably arranged on the connecting member 2 in the front-rear direction. When the seat shell 3 slides back and forth relative to the connecting member 2, the child safety seat can be placed in different usage postures, such as a sitting usage state, a semi-reclining usage state or a lying usage state.
[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the seat shell 3 includes a seat 31 for supporting the hips of a child and a backrest 32 for supporting the back of the child, and the backrest 32 extends upward from the rear of the seat 31 .
[0028] The connecting member 2 extends in the front-to-back direction, and is supported at the bottom of the seat 31 and the rear of the backrest 32. Specifically, the front of the connecting member 2 extends forward to the front of the center of the seat 31, and the rear of the connecting member 2 extends upward to the top of the center of the backrest 32. Figure 2 and Figure 4 In this way, the connecting member 2 can provide sufficient supporting strength for the seat shell 3, and when the seat shell 3 and the connecting member 2 are slidably connected, there is no need to set up an additional bracket at the bottom of the seat shell 2, so that the structure of the child safety seat is simple, the assembly is also simple, and the production of the child safety seat is convenient.
[0029] In this embodiment, Figure 6 As shown, the connecting member 2 includes an arc-shaped side panel 21 and a cross beam 22. The arc-shaped side panel 21 extends in the front-to-back direction, and two arc-shaped side panels 21 are provided, and the two arc-shaped side panels 21 are arranged at intervals in the left-right direction. The front portion of each arc-shaped side panel 21 extends forward to the front of the center of the seat 31, and the rear portion thereof extends upward to the top of the center of the backrest 32. At least one cross beam 22 is provided, and each cross beam 22 is fixedly connected between the two arc-shaped side panels 21, or is integrally formed with the two arc-shaped side panels 21.
[0030] A guide structure is also provided between the seat shell 3 and the connecting member 2. When the seat shell 3 slides relative to the connecting member 2 to adjust the use posture of the child safety seat, the guide structure guides and limits the forward and backward sliding of the seat shell 3.
[0031] like Figure 2 , Figure 4 and Figure 6 As shown, the guide structure includes a guide shaft 4 and a guide groove 211 adapted to the guide shaft 4. The guide shaft 4 is fixedly arranged on one of the seat shell 3 and the connecting member 2, and the guide groove 211 is arranged on the other of the seat shell 3 and the connecting member 2. The guide shaft 4 is located in the guide groove 211 and can be slidably arranged along the length extension direction of the guide groove 211. When the seat shell 3 slides forward and backward relative to the connecting member 2, the guide shaft 4 slides in the guide groove 211 along the length extension direction of the guide groove 211.
[0032] Preferably, the guide shaft 4 is fixedly arranged on the seat shell 3, and the guide groove 211 is arranged on the connecting member 2. This arrangement also makes it unnecessary to arrange an additional bracket at the bottom of the seat shell 3, so that the structure of the child safety seat is simple.
[0033] In this embodiment, the guide shaft 4 is fixedly arranged on the upper part of the backrest 32 and the front part of the seat 31. The guide grooves 211 are respectively arranged at the rear and front parts of the connecting member 2, and are respectively arranged on the arc-shaped side panels 21 on both sides. The guide shaft 4 located at the upper part of the backrest 32 is slidably arranged in the guide grooves 211 at the rear parts of the two arc-shaped side panels 21, and the guide shaft 4 located at the front part of the seat 31 is slidably arranged in the guide grooves 211 at the front parts of the two arc-shaped side panels 21, as shown in FIG. Figure 2 , Figure 4 and Figure 6 shown.
[0034] The child safety seat also includes a locking mechanism. When the locking mechanism is in a locked state, the relative positions of the seat shell 3 and the connecting member 2 are locked by the locking mechanism, so that the seat shell 3 cannot slide relative to the connecting member 2, and the child safety seat is kept in the current use posture. When the locking mechanism is unlocked, the seat shell 3 can slide relative to the connecting member 2, thereby adjusting the use posture of the child safety seat.
[0035] like Figure 2 to Figure 6 As shown, the locking mechanism includes a locking member 5 and a locking hole 212 adapted to the locking member 5. The locking member 5 is slidably arranged on the seat shell 3, and the locking hole 212 is arranged on the connecting member 2. When the locking mechanism is in a locked state, the locking member 5 is inserted into the locking hole 212, so that the seat shell 3 cannot slide relative to the connecting member 2, as shown in FIG. Figure 4 and Figure 5When the locking mechanism is in the unlocked state, the locking member 5 is disengaged from the locking hole 212 , so that the seat shell 3 can slide relative to the connecting member 2 .
[0036] A plurality of locking holes 212 are provided on the connecting member 2. Along the sliding direction of the seat shell 3, the plurality of locking holes 212 are arranged at intervals on the connecting member 2, such as Figure 4 and Figure 5 When the locking member 5 is inserted into different locking holes 212, the seat shell 3 is locked at different positions of the connecting member 2, so that the child safety seat is in different use postures.
[0037] In this embodiment, the locking mechanisms are respectively arranged on the left and right sides of the seat shell 3, that is, the locking members 5 are respectively slidably arranged on the left and right sides of the bottom of the seat shell 3, and correspondingly, the locking holes 212 are respectively arranged on the arc-shaped side panels 21 on both sides.
[0038] 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, so that the seat shell 3 slides forward and backward relative to the connecting member 2 to adjust the use posture of the child safety seat.
[0039] like Figure 2 , Figure 3 and Figure 6 As shown, the unlocking mechanism includes an unlocking member 6, which is slidably disposed on the seat shell 3, and the unlocking member 6 cooperates with the locking member 5. When the locking mechanism is in a locked state, the unlocking member 6 is operated to slide relative to the seat shell 3, and the unlocking member 6 acts on the locking member 5, driving the locking member 5 to slide relative to the seat shell 3, so that the locking mechanism is unlocked.
[0040] The unlocking member 6 cooperates with the locking member 5 in the following manner: Figure 2 , Figure 3 and Figure 6 As shown, the unlocking member 6 is provided with an inclined slot 61 inclined relative to its sliding direction, and the locking member 5 is fixedly provided with a positioning rod 51 adapted to the inclined slot 61. The positioning rod 51 is located in the inclined slot 61 and can be slidably arranged along the length extension direction of the inclined slot 61.
[0041] The corresponding locking members 5 are slidably arranged on the left and right sides of the bottom of the seat shell 3 , respectively. The inclined grooves 61 are arranged on the left and right sides of the unlocking member 6 , respectively. A positioning rod 51 matching the inclined groove 61 is fixedly arranged on each locking member 5 .
[0042] The child safety seat further comprises an elastic member 7, the elastic force of which is used to drive the locking mechanism to automatically reset from the unlocked state to the locked state. Figure 2 and Figure 3As shown, one end of the elastic member 7 is arranged on the unlocking member 6 , and the other end of the elastic member 7 is arranged on the seat shell 3 .
[0043] The elastic member 7 is elastically deformed during the operation of the unlocking member 6 to unlock the locking mechanism. When the unlocking member 6 is released, the elastic member 7 acts on the unlocking member 6 to make the unlocking member 6 slide back relative to the seat shell 3 and reset. When the unlocking member 6 slides, the locking member 5 is driven to slide in the direction of the insertion hole 212 through the cooperation between the inclined groove 61 and the positioning rod 51 until the locking mechanism is locked again.
[0044] Preferably, the connecting member 2 is rotatably arranged on the base 1 around a rotating shaft 8 extending in the up-down direction. In this way, when the connecting member 2 rotates around the rotating shaft 8 relative to the base 1, the seat shell 3 can be driven to rotate synchronously, so that the child safety seat can have a forward use state and a reverse use state.
[0045] When the child safety seat is in the forward use state, the child's face is facing the front of the car when the child is sitting in the child safety seat. When the child safety seat is in the reverse use state, the child's face is facing the rear of the car when the child is sitting in the child safety seat.
[0046] The connecting member 2 is also fixedly provided with a first hook 91 and a second hook 92. When the child safety seat is in the forward use state, the first hook 91 is hooked with the base 1. When the child safety seat is in the reverse use state, the second hook 92 is hooked with the base 1. When the first hook 91 is hooked with the base 1 and the second hook 92 is hooked with the base 1, the connecting member 2 can still drive the seat shell 3 to rotate around the rotating shaft 8, so that the child safety seat can be switched between the forward use state and the reverse use state. By hooking and connecting the first hook 91 with the base 1 and the second hook 92 with the base 1, the child safety seat can be prevented from sliding relative to the base 1 when a car collides in the forward use state and the reverse use state, and the seat shell 3 can also be prevented from separating from the base 1, thereby improving the safety performance of the child safety seat when in use.
[0047] In this embodiment, the connector 2 further includes a cover 23 covering the bottom of the arc-shaped side plate 21 and the crossbeam 22. The cover 23 is provided with slots at positions corresponding to the rotating shaft 8, the first hook 91 and the second hook 92. The rotating shaft 8, the first hook 91 and the second hook 92 pass through the slots at corresponding positions and are connected to the base 1. The provision of the cover 23 can make the overall structure formed by connecting the seat shell 3 and the connector 2 neat and beautiful.
[0048] 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.
