DETAILED DESCRIPTION

[0050] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0051] Example 1

[0052] like Figure 1 to Figure 19 As shown, the child safety seat with a carrier of the present invention comprises a base 1 , a carrier 2 detachably arranged on the base 1 , and a protective block 3 .

[0053] The carrying basket 2 includes a seat portion 21 for supporting the buttocks of an infant, a backrest 22 for supporting the back of an infant, and side guards 23. The seat portion 21 extends obliquely downward from front to rear, and the backrest 22 extends obliquely backward and upward from the rear of the seat portion 21. The seat portion 21 and the backrest 22 are integrally arranged, and the side guards 23 extend in the front-to-back direction. The front portion of the side guards 23 is fixedly arranged at the front of the seat portion 21, and the rear portion is fixedly arranged on the backrest 22.

[0054] The protective block 3 is located on the outside of the base 1, and the front end of the protective block 3 is rotatably set on the base 1 through the rotating shaft 8. The rotating shaft 8 can extend in the left and right direction or in the up and down direction. In this way, the protective block 3 can rotate up and down around the rotating shaft 8 relative to the base 1, or rotate left and right around the rotating shaft 8 relative to the base 1.

[0055] When the protective block 3 rotates up and down relative to the base 1, the protective block 3 may include side guardrails 31 located on the left and right sides and a horizontal guardrail 32 connected between the side guardrails 31 on the left and right sides. The protective fence 3 as a whole is a U-shaped structure with its opening facing forward, and the front ends of the side guardrails 31 on the left and right sides are rotatably connected to the base 1 through the rotating shaft 8.

[0056] When the protection block 3 rotates left and right relative to the base 1 , the protection block 3 only includes the side guardrails 31 on the left and right sides, and the front ends of the side guardrails 31 on the left and right sides are rotatably connected to the base 1 through the rotating shaft 8 .

[0057] The child safety seat further comprises a first locking mechanism for locking the position of the protection block 3 , wherein the first locking mechanism has a locking state and an unlocking state.

[0058] When the first locking mechanism is in the locked state, the position of the protection block 3 relative to the base 1 is fixed, and the protection block 3 stands on the outside of the basket 2. In this embodiment, the side guardrails 31 and the side stopper 23 of the protection block 3 extend in the same direction, and the protection block 3 is located on the outside of the side stopper 23. In this way, when a side collision occurs to the car, the ability of the basket 2 to withstand the side impact load can be increased, and the damage to the infant caused by the impact load during the side collision can be effectively reduced, thereby forming a safety protection for the infant lying in the basket 2. Figure 1 and Figure 3 shown.

[0059] When the first locking mechanism is in the unlocked state, the protective block 3 can be rotated downward relative to the base 1 to be located at the lower part of the base 1 and the outside of the base 1, or rotated to the outside of the child safety seat of the basket, so that the protective block 3 is away from the basket 2, which is convenient for operation and removal of the basket 2 from the base 1. When the basket 2 is installed on the base 1, the first locking mechanism is also in the unlocked state, and the protective block 3 is also rotated downward relative to the base 1 to be located at the lower part of the base 1 and the outside of the base 1, or rotated to the outside of the child safety seat of the basket, so that the part of the base 1 where the basket 2 is installed is basically exposed, which is convenient for operation and installation of the basket 2 on the base 1. Regardless of installing or removing the basket 2, most of the space occupied by the protective block 3 overlaps with the base 1, so that the space occupied by the protective block 3 alone is smaller, that is, only a small space needs to be reserved to realize the up and down flipping of the protective block 3, which facilitates the use of the child safety seat of the basket, such as Fig. 9 shown.

[0060] The side guardrail 31 of the protective block 3 is preferably of the same structure as the side stop 23. Thus, when the protective block 3 is supported on the outside of the side stop 23, the side stop 23 can be completely shielded, so that the side impact load generated by the collision of the car is transmitted to the side stop 23 through the protective block 3, which can effectively reduce the side impact load borne by the carrier 2 and make the overall appearance of the carrier child safety seat beautiful and neat. Figure 3 shown.

[0061] Preferably, the upper structure of the side guardrail 31 of the protection block 3 matches the upper structure of the side of the base 1, which can also make the overall appearance of the child safety seat of the basket beautiful and neat. Specifically, the upper part of the side guardrail 31 of the protection block 3 and the upper part of the side of the base 1 are both arc-shaped structures. The setting of the arc area can also form an avoidance space for the handle on the basket 2, such as Figure 1 and Figure 2 shown.

[0062] The first locking mechanism is disposed between the protection block 3 and the base 1 to lock the relative position of the two. Figure 10~Figure 13 As shown, the first locking mechanism includes a first locking pin 41 slidably disposed on one of the two components of the protection block 3 and the base 1 and a locking groove 11 disposed on the other of the two components of the protection block 3 and the base 1, and the locking groove 11 matches the first locking pin 41. When the first locking mechanism is in a locked state, the first locking pin 41 is inserted into the locking groove 11, as shown in FIG. Fig.10 and Fig.11 When the first locking mechanism is in the unlocked state, the first locking pin 41 comes out of the lock slot 11, as shown Fig.12 and Fig.13In this embodiment, the first locking pin 41 is slidably disposed on the horizontal guardrail 32 of the protection block 3 in the front-rear direction, and the locking slot 11 is disposed at the rear of the base 1 .

[0063] The child safety seat also includes a first unlocking mechanism for driving the first locking mechanism to unlock. Figure 10~Figure 13 As shown, the first unlocking mechanism includes a first unlocking member 5 that can be slidably arranged on the base 1 or the protective block 3, and the first unlocking member 5 is connected to or matched with the first lock pin 41. When the first unlocking member 5 is operated to slide relative to the base 1 or the protective block 3, the first lock pin 41 can be driven to slide relative to the base 1 or the protective block 3, thereby escaping from the lock slot 11, and the first locking mechanism is unlocked. In this embodiment, the first unlocking member 5 can be slidably arranged on the horizontal guardrail 32 of the protective block 3 in the front-to-back direction, and the first unlocking member 5 is fixedly connected to or integrally arranged with the first lock pin 41.

[0064] The first locking mechanism also includes a first elastic member 42 for driving the first locking mechanism to return from the unlocked state to the locked state. In this embodiment, the first elastic member 42 is a spring, and both ends of the spring are respectively arranged on the first unlocking member 5 and the protective block 3.

[0065] When the first locking mechanism is in the locked state, the carrier 2 can also be installed on the base 1, or the carrier 2 can be removed from the base 1, but the operation is inconvenient. When the first locking mechanism is unlocked by the first unlocking mechanism, the protective block 3 is rotated downward relative to the base 1 to be located at the lower part of the base 1, or the protective block 3 is rotated relative to the base 1 to the outside of the carrier child safety seat, it is more convenient to install or remove the carrier 2.

[0066] Of course, the first locking mechanism can also be arranged between the protection block 3 and the basket 2 to lock the relative position of the two. In this case, the first locking mechanism is specifically arranged between the horizontal guardrail 32 of the protection block 3 and the backrest 22 of the basket 2. In this state, when the first locking mechanism is in the locked state, the basket 2 cannot be installed on the base 1, or the basket 2 cannot be removed from the base 1. The basket 2 can only be installed or removed when the first locking mechanism is unlocked, the protection block 3 is rotated downward relative to the base 1 to the lower part of the base 1, or the protection block 3 is rotated relative to the base 1 to the outside of the basket child safety seat.

[0067] The child safety seat with a carrier also includes a second locking mechanism for locking the relative position of the carrier 2 and the base 1 after the carrier 2 is mounted on the base 1, and a second unlocking mechanism for driving the second locking mechanism to unlock. When the second locking mechanism is in a locked state, the carrier 2 is fixed to the base 1, and when the second unlocking mechanism is operated to unlock the second locking mechanism, the carrier 2 can be removed from the base 1.

[0068] Specifically, Figure 14~Figure 19As shown, the second locking mechanism includes a second locking pin 61 fixedly arranged on the basket 2 and a locking hook 62 rotatably arranged on the base 1, and the locking hook 62 has a hook groove matching the second locking pin 61. When the second locking mechanism is in a locked state, the second locking pin 61 is clamped in the hook groove of the locking hook 62, as shown in FIG. Fig.14 and Fig.16 When the second locking mechanism is in the unlocked state, the second locking pin 61 is disengaged from the hook groove 62 of the lock hook, as shown Fig.17 and Fig.19 shown.

[0069] like Figure 14~Figure 19 As shown, the second unlocking mechanism includes a second unlocking member 71 and a first connecting member 72 which can be slidably arranged on the base 1, one end of the first connecting member 72 is connected to the second unlocking member 71, and the other end of the first connecting member 72 is connected to the lock hook 62. When the second locking mechanism is in a locked state, when the second unlocking member 71 is operated to slide relative to the base 1, the lock hook 62 is pulled by the first connecting member 72 to rotate relative to the base 1, so that the second lock pin 61 is disengaged from the hook groove of the lock hook 62, and the second locking mechanism is unlocked. In this embodiment, the first connecting member 72 adopts a first flexible connecting member, such as the first connecting member 72 adopts a traction rope, and the two ends of the traction rope are respectively fixedly arranged on the second unlocking member 71 and the lock hook 62.

[0070] The second locking mechanism further includes a second elastic member 63 for driving the second locking mechanism to return from the unlocked state to the locked state. In this embodiment, the second elastic member 63 is a tension spring, and both ends of the tension spring are respectively arranged on the lock hook 62 and the base 1.

[0071] In this embodiment, the second locking mechanisms are respectively arranged on the left and right sides of the backrest portion 22 of the basket 2 and between the seat portion 21 and the base 1, and the lock hook 62 of each second locking mechanism is connected to the second unlocking member 71 through a traction rope.

[0072] How to use the child safety seat:

[0073] When the child safety seat with the carrier is needed, the base 1 connected with the protection block 3 is first fixed to the car seat; the first unlocking member 5 is pulled to slide relative to the protection block 3, thereby driving the first lock pin 41 to slide in the direction of getting out of the first lock groove 11 until the first locking mechanism is unlocked; the protection block 3 is rotated around the rotation axis 8 to the lower part of the base 1 or the left and right sides of the base 1; the carrier 2 is placed on the base 1, and when the carrier 2 is placed downward to the bottom of the carrier 2 and conflicts with the lock hook 62, the lock hook 62 is rotated relative to the base 1 by a certain angle under the action of the weight of the carrier 2 itself, so that the carrier 2 can continue to move downward to be installed with the base 1. When the carrier 2 is placed in place, the elastic force of the second elastic member 63 drives the lock hook 62 to rotate in the opposite direction, so that the second lock pin 61 enters the hook groove of the lock hook 62, and the second locking mechanism is in a locked state; after the protection block 3 is rotated upward around the rotation axis 8 or to the inner side of the carrier child safety seat to a set position, the position of the protection block 3 and the base 1 can be locked again by the first locking mechanism. In this way, the child safety seat with a carrier is installed on the car seat.

[0074] When it is necessary to remove the child safety seat with the carrier from the car seat, first operate the first unlocking member 5 to unlock the first locking mechanism. After the first locking mechanism is unlocked, the protective block 3 is rotated around the rotating shaft 8 to the lower part or the left and right sides of the base 1; then operate the second unlocking member 71 to make it slide relative to the base 1, and pull the lock hook 62 to rotate relative to the base 1 through the traction rope, so that the second lock pin 61 is disengaged from the hook groove of the lock hook 62, and the second locking mechanism is unlocked. At this time, the carrier 2 can be removed from the base 1. After the carrier 2 is removed, the base 1 can be removed from the car seat.

[0075] Of course, when the basket 2 needs to be disassembled, the first locking mechanism can be kept locked all the time, and the basket 2 can be disassembled from the base 1 only by operating the second unlocking mechanism to unlock the second locking mechanism. However, this makes it inconvenient to take out the basket 2.

[0076] Example 2

[0077] In this embodiment, the unlocking operations of the first locking mechanism and the second locking mechanism can be realized in linkage, and there is no need to separately provide a second unlocking mechanism. Only the first unlocking mechanism needs to be operated to simultaneously unlock the first locking mechanism and the second locking mechanism.

[0078] Specifically, the child safety seat in the basket also includes a linkage structure arranged between the first unlocking member 5 and the lock hook 62, the linkage structure includes a slider 91 that can be slidably arranged on the base 1 in the up and down directions, the slider 91 and the first lock pin 41 are matched through an inclined surface, and the slider 91 and the lock hook 62 are connected through a second flexible connecting member 92.

[0079] In this embodiment, the first locking pin 41 is slidably disposed on the horizontal guardrail 32 of the protection block 3 in the front-rear direction, and the locking slot 11 is disposed on the base 1 .

[0080] When both the first locking mechanism and the second locking mechanism are in the locked state, when the first unlocking member 5 is operated to slide relative to the protective block 3, the first lock pin 41 can be pulled to slide relative to the protective block 3 and disengage from the lock groove 11, and the first locking mechanism is unlocked; when the first unlocking member 5 slides relative to the protective block 3, the inclined surface between the slider 91 and the first lock pin 41 cooperates to drive the slider 91 to slide upward relative to the base 1, and the lock hook 62 is pulled to rotate relative to the base 1 through the second flexible connecting member 92, so that the second lock pin 61 is disengaged from the hook groove of the lock hook 62, and the second locking mechanism is unlocked. Figure 20~Figure 23 shown.

[0081] The linkage structure further includes a third elastic member 93 for driving the slider 91 to return to its original position. The third elastic member 93 is a spring, and both ends of the spring are respectively arranged on the slider 91 and the base 1 .

[0082] Example 3

[0083] In this embodiment, the unlocking operations of the first locking mechanism and the second locking mechanism can also be realized in linkage, without separately providing the first unlocking mechanism, that is, only operating the second unlocking mechanism can simultaneously unlock the first locking mechanism and the second locking mechanism.

[0084] In this embodiment, the first locking pin 41 is slidably disposed on the base 1 , and the locking slot 321 is disposed on the horizontal guardrail 32 of the protection block 3 .

[0085] The child safety seat also includes a third flexible connector 10 at both ends of which are respectively fixedly connected to the first locking pin 41 and the second unlocking member 71. In this embodiment, the first elastic member 42 is disposed between the first locking pin 41 and the base 1.

[0086] When both the first locking mechanism and the second locking mechanism are in the locked state, when the second unlocking member 71 is operated to slide relative to the base 1, the lock hook 62 is pulled by the first connecting member 72 to rotate relative to the base 1, so that the second lock pin 61 is disengaged from the hook groove of the lock hook 62, and the second locking mechanism is unlocked. At the same time, the first lock pin 41 is pulled by the third flexible connecting member 10 to slide relative to the base 1 and disengage from the lock groove 321, and the first locking mechanism is unlocked.

[0087] Example 4

[0088] In this embodiment, when the first locking mechanism is unlocked and the protection block 3 rotates relative to the base 1 in a direction away from the base 1, the second locking mechanism can be unlocked. In this way, there is no need to set up a second unlocking mechanism separately.

[0089] Specifically, the child safety seat also includes a second connecting member 110, one end of which is fixedly connected to the side guardrail 31, and the other end of which is fixedly connected to the lock hook 62. Fig.28 and Fig.33 In this embodiment, the second connecting member 110 is a fourth flexible connecting member.

[0090] In this embodiment, the specific structures of the first locking mechanism and the first unlocking mechanism are the same as those in Embodiment 1, the first lock pin 41 and the first unlocking member 5 are fixedly connected or integrally arranged, and both can be slidably arranged on the side guardrail 31 along the front-rear direction, and the lock slot 11 is arranged at the rear of the base 1. Figure 29~Figure 32 shown.

[0091] When the first unlocking member 5 is operated to unlock the first locking mechanism, the protective block 3 can be rotated downward relative to the base 1 or toward the outside of the child safety seat in the basket to move away from the base 1. During the rotation of the protective block 3, the fourth flexible connecting member is pulled, and the lock hook 62 is pulled by the fourth flexible connecting member to rotate relative to the base 1, so that the second lock pin 61 is disengaged from the hook groove of the lock hook 62, and the second locking mechanism is unlocked.

[0092] The above definitions of direction are all based on the infant lying in the basket, with the infant's face facing forward.

[0093] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
