Description

Technical Field

[0001] The invention relates to the technical field of children's products, in particular to a child car seat. Background Art

[0002] Child car seats are widely used because they can provide safety protection for children when riding in a car. The child car seat includes a seat body and a stopper detachably arranged on the seat body. The stopper is used to protect the safety of the child sitting on the child car seat. The stopper is generally used when the child is small, and the stopper is no longer used when the child is older. When the stopper is used for safety protection, the stopper and the child car seat need to be connected and locked by a locking mechanism. The child car seat in the prior art is only provided with one locking mechanism, which is easy to be unlocked by misoperation, so that the connection between the stopper and the seat body is disconnected, and the stopper cannot play a role in safety protection. In addition, when the child is larger and is not suitable for using the stopper, the child car seat in the prior art cannot prevent the stopper from being connected to the seat body, so that the child car seat cannot play an effective safety protection role due to the misuse of the stopper. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved child car seat.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A child car seat comprises a seat body, a stopper detachably arranged on the seat body, a first locking mechanism arranged between the stopper and the seat body for connecting and locking the two, and a first unlocking mechanism for driving the first locking mechanism to unlock. The child car seat also comprises a second locking mechanism for preventing the first unlocking mechanism from operating to unlock the first locking mechanism when the stopper and the seat body are connected, and a second unlocking mechanism for driving the second locking mechanism to unlock. The second locking mechanism and the second unlocking mechanism are both arranged on the seat body.

[0006] Preferably, the first unlocking mechanism includes an unlocking piece that can be slidably arranged on the seat body, and the two-way lock mechanism includes a first limiting piece that can be rotatably arranged on the seat body. When the two-way lock mechanism is in a locked state, the first limiting piece is in a first working position, the first limiting piece cooperates with the unlocking piece, and the unlocking piece cannot slide relative to the seat body. When the two-way lock mechanism is in an unlocked state, the first limiting piece is in a second working position, the cooperation between the first limiting piece and the unlocking piece is disengaged, and the unlocking piece can slide relative to the seat body, thereby unlocking the first lock mechanism.

[0007] Furthermore, the second unlocking mechanism includes an operating member and a sliding member slidably disposed on the seat body, and a traction rope having two ends respectively connected to the operating member and the sliding member, and the sliding member cooperates with the first limiting member.

[0008] Furthermore, the seat body includes a backrest, a head support assembly slidably disposed on the backrest, and a head support limiter for limiting the height range of the head support assembly when in use, the head support limiter can be slidably disposed on the backrest, and the head support limiter is partially clamped on the head support assembly, and the operating member is the head support limiter.

[0009] Furthermore, the seat body includes a base, the child car seat includes a buckle seat fixedly arranged on the base for connecting the block, the sliding member can be slidably arranged inside the buckle seat, the operating member can be slidably arranged on the base, and the operating member is separately arranged from the buckle seat.

[0010] Preferably, the child car seat further comprises an anti-connection mechanism for preventing the stopper from being connected and locked with the seat body through the first locking mechanism after the stopper is separated from the seat body, and the anti-connection mechanism is arranged on the seat body.

[0011] Further, the first locking mechanism includes an insert plate arranged on the block and connected to and locked with the seat body, and the anti-connection mechanism includes a second limit member rotatably arranged on the seat body, and the second limit member has a first working position and a second working position. When the second limit member is in the first working position, the second limit member is away from the path of the insert plate inserted into the seat body, and when the second limit member is in the second working position, the second limit member blocks the path of the insert plate inserted into the seat body.

[0012] Furthermore, the child car seat also includes a pad that can be slidably arranged on the seat body. When the first locking mechanism is locked, the insert is abutted against the pad and pushes the pad to slide relative to the seat body. When the second limiting member is in the first working position, the second limiting member is away from the pad. When the second limiting member is in the second working position, the second limiting member is abutted against the pad.

[0013] Furthermore, the first unlocking mechanism includes an unlocking piece that can be slidably arranged on the seat body, and the two-way lock mechanism includes a first limiting piece that can be rotatably arranged on the seat body. When the two-way lock mechanism is in a locked state, the first limiting piece is in a first working position, the first limiting piece cooperates with the unlocking piece, and the unlocking piece cannot slide relative to the seat body. When the two-way lock mechanism is in an unlocked state, the first limiting piece is in a second working position, the cooperation between the first limiting piece and the unlocking piece is disengaged, and the unlocking piece can slide relative to the seat body to unlock the first lock mechanism. The first limiting piece and the second limiting piece are fixedly connected. When the first limiting piece is in the first working position, the second limiting piece is in the first working position, and when the first limiting piece is in the second working position, the first limiting piece is in the second working position.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1~Figure 3 As shown, the child car seat of the present invention comprises a seat body 1 and a stopper 2 detachably arranged on the seat body 1 .

[0028] The seat body 1 includes a base 11, a backrest 12 disposed on the base 11, a head support assembly 13 slidably disposed on the backrest 12, and a head support stopper 14 for limiting the height range of the head support assembly 13 when in use. The head support stopper 14 is slidably disposed on the backrest 12, and a portion of the head support stopper 14 is clamped on the head support assembly 13. The head support assembly 13 can be limited to use in area A or area B through the head support stopper 14. Area A is suitable for use by younger children, and area B is suitable for use by older children.

[0029] Specifically, Figure 4 As shown, the head support assembly 13 is provided with a first limiting groove 131 and a second limiting groove 132, both of which extend in the up-down direction, and the first limiting groove 131 is located above the second limiting groove 132, the lower end of the first limiting groove 131 and the upper end of the second limiting groove 132 are connected, and the head support limiting member 14 is partially inserted into the first limiting groove 131 or the second limiting groove 132. When the head support assembly 13 is used within the range of area A, the head support limiting member 14 is partially inserted into the first limiting groove 131, and can be slidably arranged relative to the first limiting groove 131 along the length extension direction of the first limiting groove 131, so as to adjust the height of the head support assembly 13. When the headrest assembly 13 is used within the range of zone B, the headrest stopper 14 is partially inserted into the second stopper groove 132, and can be slidably arranged relative to the second stopper groove 132 along the length extension direction of the second stopper groove 132, so as to adjust the height of the headrest assembly 13. The headrest stopper 14 can slide relative to the backrest 12, so as to enter the second stopper groove 132 from the first stopper groove 131, or enter the first stopper groove 131 from the second stopper groove 132.

[0030] The stopper 2 is generally used when the child is small, but is no longer used when the child grows up. The child car seat also includes a first locking mechanism for connecting and locking the stopper 2 to the seat body 1 when the stopper 2 is used, and a first unlocking mechanism for unlocking the first locking mechanism to remove the stopper 2 from the seat body 1.

[0031] A buckle seat 4 is fixedly provided on the seat body 1, and the first locking mechanism includes an insert 32 connected to the block 2 and a locking piece 33 rotatably provided on the buckle seat 4 and capable of cooperating with the insert 32. When the first locking mechanism is in a locked state, the insert 32 is inserted into the buckle seat 4 and cooperates with the locking piece 33. When the first locking mechanism is unlocked, the cooperation between the insert 32 and the locking piece 33 is disengaged.

[0032] In this embodiment, a strap 31 is fixedly connected or tied to the stopper 2, and the insert 32 is connected to the strap 31. Figure 5 shown.

[0033] The insert 32 is provided with a slot 321 , and the locking piece 33 is provided with a lock hook 331 matching with the slot 321 . When the first lock mechanism is in a locked state, the lock hook 331 is stuck in the slot 321 , and when the first lock mechanism is in an unlocked state, the lock hook 331 is disengaged from the slot 321 .

[0034] The child car seat also includes a pad 34 that can be slidably arranged on the buckle seat 4. When the first locking mechanism is in an unlocked state, the lock hook 331 is abutted against the pad 34. When the insert 32 is inserted into the buckle seat 4 to connect and lock the block 2 with the seat body 1, the insert 32 and the pad 34 are abutted, driving the pad 34 to slide relative to the buckle seat 4, and the lock hook 331 gradually moves away from the pad 34 until the lock hook 331 is inserted into the slot 321, and the first locking mechanism is locked.

[0035] The first unlocking mechanism comprises an unlocking member 5 slidably disposed on the buckle seat 4. When the unlocking member 5 is pressed, the first locking mechanism can be driven to unlock.

[0036] In this embodiment, the specific structure of the first locking mechanism and the first unlocking mechanism is the same as the locking and unlocking structure of the buckle assembly in the seat belt assembly in the prior art, and will not be repeated here. Of course, the first locking mechanism and the first unlocking mechanism may also adopt a structure different from the buckle assembly.

[0037] In order to increase the safety performance when the stopper 2 is used, the child car seat also includes a second locking mechanism for preventing the first unlocking mechanism from operating to unlock the first locking mechanism when the stopper 2 is in use, that is, after the stopper 2 and the seat body 1 are connected and locked.

[0038] like Figure 6~Figure 9 As shown, the two-way lock mechanism includes a first limit member 61 rotatably arranged on the buckle seat 4, and the first limit member 61 has a first working position and a second working position. When the first limit member 61 is in the first working position, that is, the two-way lock mechanism is in the locking member state, the first limit member 61 cooperates with the unlocking member 5, so that the unlocking member 5 cannot slide relative to the buckle seat 4, so that the first lock mechanism cannot be unlocked, and the insert 32 and the locking member 33 are always in a matched state, as shown in FIG. Figure 7 and Figure 8 When the first position-limiting member 61 rotates relative to the buckle seat 4 to the second working position, that is, the two-way lock mechanism is in the unlocked state, the first position-limiting member 61 and the unlocking member 5 are disengaged, and the unlocking member 5 can slide relative to the buckle seat 4, thereby driving the locking member 33 to rotate relative to the buckle seat 4 and disengage the engagement with the insert 32, and the first lock mechanism is unlocked. At this time, the insert 32 can be pulled out of the buckle seat 4, so that the stopper 2 is removed from the seat body 1, as shown in FIG. Fig. 9 shown.

[0039] like Figure 6~Figure 9As shown, the child car seat also includes a second unlocking mechanism for unlocking the two-way lock mechanism, the second unlocking mechanism includes a sliding member 71, a traction rope 72 and an operating member 73, the sliding member 71 can be slidably arranged in the inner cavity of the buckle seat 4, the sliding member 71 cooperates with the first limiter 61, the operating member 73 can be slidably arranged on the seat body 1, and the two ends of the traction rope 72 are respectively connected to the sliding member 71 and the operating member 73. When the two-way lock mechanism is in a locked state, the operating member 73 is operated to slide relative to the seat body 1, and the sliding member 71 is pulled by the traction rope 72 to slide relative to the buckle seat 4. During the sliding process of the sliding member 71, the first limiter 61 is driven to rotate through the cooperation between the sliding member 71 and the first limiter 61, until the cooperation between the first limiter 61 and the unlocking member 5 is disengaged, and the second limiter 61 is in the second working position, that is, the two-way lock mechanism is unlocked, and at this time, the unlocking member 5 can be operated to slide relative to the buckle seat 4, so as to unlock the first lock mechanism.

[0040] The operating member 73 can be the same component as the head support limiter 14, that is, the head support limiter 14 is connected to the traction rope 72. When the child is small, the block 2 needs to be used. When the block 2 and the seat body 1 are connected and locked, the head support assembly 13 is used within the A area, that is, the head support limiter 14 is partially inserted into the first limiter groove 131. At this time, the first limiter 61 cooperates with the unlocking member 5 to avoid misoperation of the unlocking member 5 to unlock the first lock mechanism, so that the block 2 and the seat body 1 are in a stable connection and locking state. When the block 2 is no longer needed, the head support limit member 14, i.e., the operating member 73, is made to slide relative to the backrest 12, and the head support limit member 14 slides from the first limit groove 131 into the second limit groove 132. At this time, the head support assembly 13 can be used within the range of zone B. During the sliding process of the head support limit member 14, i.e., the operating member 73 relative to the backrest 12, the first limit member 61 can be rotated relative to the buckle seat 4 to the second working position through the action of the traction rope 72 and the sliding member 71, that is, the two-way locking mechanism is in an unlocked state. At this time, the unlocking member 5 can be operated to slide relative to the buckle seat 4 to unlock the first locking mechanism. After the first locking mechanism is unlocked, the block 2 can be removed from the seat body 1.

[0041] Of course, the operating member 73 can also be a different component from the headrest limiter 14, and a separate operating member 73 can be set for use when unlocking the second lock mechanism, such as sliding the operating member 73 on the base 11, and the operating member is away from the buckle seat 4, such as Figure 2 As shown, at this time, the head support limiter 14 is not connected to the traction rope 72, and the head support limiter 14 is only used to limit the head support assembly 13 to be used in the A area or the B area.

[0042] The two-way locking mechanism also includes a first elastic member 62 for driving the first limit member 61 to rotate relative to the buckle seat 4 so as to reset the two-way locking mechanism from the unlocked state to the locked state. In this embodiment, the first elastic member 62 is a tension spring, and the two ends of the tension spring are respectively clamped on the first limit member 61 and the buckle seat 4.

[0043] The child car seat further comprises a second elastic member 63 for driving the sliding member 71 to slide and reset relative to the buckle seat 4. In this embodiment, the second elastic member 63 is a spring, and the two ends of the spring are respectively disposed on the buckle seat 4 and the sliding member 71. By providing the second elastic member 63, the requirement for the elastic force of the first elastic member 62 can be reduced.

[0044] When the two-way lock mechanism is unlocked, the operating member 73 is operated to slide in the reverse direction, and the traction rope 72 is loosened. Under the elastic force of the first elastic member 62 and the second elastic member 63, the first limit member 61 can be driven to rotate in the reverse direction and reset, and the sliding member 71 can slide in the reverse direction and reset.

[0045] When the child grows up, in order to improve the safety performance of the child car seat, the stopper 2 can no longer be used. The child car seat also includes an anti-connection mechanism for preventing the stopper 2 from being connected and locked with the seat body 1 through the first locking mechanism when the stopper 2 is not in use, that is, after the stopper 2 and the seat body 1 are separated.

[0046] The anti-connection mechanism includes a second limit member 8 rotatably arranged on the buckle seat 4, and the second limit member 8 has a first working position and a second working position. When the second limit member 8 is in the first working position, the second limit member 8 is away from the path of the plug piece 32 when it is inserted into the buckle seat 4. When the second limit member 8 is rotated relative to the buckle seat 4 to be in the second working position, the second limit member 8 blocks the path of the plug piece 32 when it is inserted into the buckle seat 4, thereby preventing the plug piece 32 from being inserted into the buckle seat 4.

[0047] In this embodiment, when the second stopper 8 is in the first working position, the second stopper 8 is away from the backing plate 34. When the second stopper 8 is in the second working position, the second stopper 8 is against the backing plate 34, so that when the inserting piece 32 is inserted into the buckle seat 4, it cannot push the backing plate 34 to slide relative to the buckle seat 4, that is, the inserting piece 32 cannot be inserted into the buckle seat 4.

[0048] The second limiting member 8 is fixedly connected to the first limiting member 61. When the first limiting member 61 rotates relative to the buckle seat 4, the second limiting member 8 is also driven to rotate relative to the buckle seat 4. When the first limiting member 61 is in the first working position, the second limiting member 8 is in the first working position. When the first limiting member 61 rotates relative to the buckle seat 4 to the second working position, the second limiting member 8 rotates relative to the buckle seat 4 to the second working position. That is, when the stopper 2 and the seat body 1 are connected and locked, the second limiting member 8 is in the first working position. When the stopper 2 and the seat body 1 are separated, the second limiting member 8 is in the second working position.

[0049] When the head support limiter 14 is used as the operating member 73, when the head support assembly 13 is used within the range of zone A, that is, when the head support limiter 14 is partially inserted into the first limiter groove 131, the first limiter 61 is in the first working position, the second limiter 8 is in the first working position, at this time, the stopper 2 and the seat body 1 are connected and locked, and the unlocking member 5 cannot slide relative to the buckle seat 4 to unlock the first lock mechanism. When the head support limiter 14 slides from the first limiter groove 131 to the second limiter groove 132, the first limiter 61 drives the second limiter 8 to rotate relative to the buckle seat 4 through the traction rope 72 and the sliding member 71. When the head support limiter 14 slides into the second limiter groove 132, the first limiter 61 is in the second working position, the unlocking member 5 can slide relative to the buckle seat 4 to unlock the first lock mechanism, the second limiter 8 is in the second working position, and the insert 32 cannot be inserted into the buckle seat 4, that is, the stopper 2 cannot be connected and locked with the seat body 1.

[0050] 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.
