[0023] A child safety seat is a seat designed specifically for children, installed in a car, and effectively improves children's safety while traveling in a vehicle.

[0024] To accommodate children of different ages and weights, child safety seats generally need to be able to be installed in both forward and rear-facing positions. This is to provide protection for young infants when installed rear-facing, and to make it more comfortable for older children when installed forward-facing. To achieve these two installation methods and to allow switching between them, corresponding installation adjustment structures are needed to meet functional requirements.

[0025] In view of this, the present invention proposes a child safety seat, please refer to [link / reference]. Figures 1 to 16 The following is a detailed description of the child safety seat proposed in this application, with reference to the specific accompanying drawings.

[0026] Please see Figures 1 to 16The child safety seat 100 includes a base 1, a fixed seat 2, a support member 3, a locking structure 4, and an unlocking member 5. The base 1 is supported on the vehicle support member 3. The fixed seat 2 is disposed on the base 1. The support member 3 is detachably disposed on the fixed seat 2. The locking structure 4 includes a locking component 41 and a locking mating member 42. The locking component 41 is disposed on one of the fixed seat 2 and the support member 3, and the locking component 41 includes two locking hooks 411 and two anti-rotation members 412 disposed opposite to each other along a first horizontal direction. The locking hooks 411 extend along a second horizontal direction. The axis is rotatably configured to have a locked position and an unlocked position. Each of the two anti-rotation members 412 has a first position and a second position in its active stroke. In the first position, the anti-rotation member 412 restricts the corresponding locking hook 411 from rotating toward the unlocked position. In the second position, the restriction on the locking hook 411 from rotating toward the unlocked position is released. The locking engagement member 42 is disposed on the other side of the fixed base 2 and the carrier member 3. The unlocking member 5 is drivenly connected to the two anti-rotation members 412 to drive the two anti-rotation members 412 to switch between the first position and the second position.

[0027] In the technical solution of this invention, the child safety seat 100 includes a base 1, on which a fixed seat 2 is mounted. The carrier 3 can be detachably mounted to the fixed seat 2 via a locking structure 4. The locking structure 4 includes a locking component 41 and a locking mating component 42. The locking component 41 includes two locking hooks 411 and two anti-rotation components 412. One locking hook 411 and one anti-rotation component 412 cooperate to give the locking structure 4 two locking points. The locking mating components 42 cooperate accordingly. Thus, while ensuring the installation stability of the carrier 3, the carrier 3 can be detached. The two sets of oppositely arranged locking hooks 411 and anti-rotation components 412 can lock the carrier 3 in two directions, thereby meeting the requirements for forward and reverse installation of the carrier 3. It can also switch between forward and reverse installation methods to meet functional requirements. The unlocking component 5 is used to unlock the locked installation state of the carrier 3 to meet the disassembly requirements of the carrier 3.

[0028] Specifically, the fixing seat 2 is rotatably mounted on the base 1, allowing the fixing seat 2 to drive the carrier 3 to rotate. This enables adjustment of the orientation of the carrier 3 to meet different orientation requirements, including but not limited to rotating the carrier 3 to face outwards from the vehicle to facilitate placing a child on it. It can even include adjusting the forward and reverse orientation of the installed carrier 3; that is, the carrier 3 can be installed in any orientation on the fixing seat 2, and the fixing seat 2 can be rotated and adjusted to position the carrier 3 to the desired orientation. Of course, in some embodiments, the fixing seat 2 can also be fixedly mounted on the base 1. Specific implementation methods depend on actual needs and are not specifically limited here.

[0029] Furthermore, the locking hook 411, in conjunction with the locking engagement member 42, can install and fix the carrier member 3 to the fixing base 2. The anti-rotation member 412 is used to limit the locking hook 411, so that the locking hook 411 can at least be maintained in the locked position, keeping it locked and fixed with the locking engagement member 42. The unlocking member 5 acts on the anti-rotation member 412 to drive the anti-rotation member 412 to switch between a first position that restricts the locking hook 411 from rotating toward the unlocked position and a second position that releases the restriction on the rotation of the locking hook 411 toward the unlocked position, so that the locking hook 411 can be unlocked or locked.

[0030] Specifically, the locking structure 4 further includes a movable connector 43, which connects the two anti-rotation members 412 so that the two anti-rotation members 412 can switch between the first position and the second position during its active stroke; the unlocking member 5 is connected to the connector 43 so that the connector 43 can move. That is, in this embodiment, the two anti-rotation members 412 are connected through the connector 43 so that the two anti-rotation members 412 can switch synchronously between the corresponding first position and the second position, that is, they can lock or unlock the corresponding lock hooks 411 synchronously. The unlocking member 5 is then set to be connected to the connector 43 so that the two anti-rotation members 412 can be controlled to move synchronously by one action of the unlocking member 5, thereby realizing synchronous control of the two lock hooks 411 and simplifying the unlocking and locking operations. Of course, in other embodiments, the two anti-rotation members 412 can also be set independently, and the unlocking member 5 can also be set independently, that is, one unlocking member 5 is set to drive the corresponding anti-rotation member 412 to move.

[0031] Further, the two anti-rotation members 412 include a first anti-rotation member 412a and a second anti-rotation member 412b that are movably configured. The first anti-rotation member 412a is rotatably configured along an axis extending in a second horizontal direction, and the second anti-rotation member 412b is slidably configured along a first horizontal direction. The connecting member 43 is slidably configured along the first horizontal direction. A first transmission structure 44 is provided between the connecting member 43 and the first anti-rotation member 412a. The first transmission structure 44 is used to drive the first anti-rotation member 412a to rotate when the connecting member 43 slides along the first horizontal direction. The second anti-rotation member 412b is fixedly configured on the connecting member 43. It should be noted that, based on the specific structural configuration of the child safety seat 100, the adjustment methods of the first anti-rotation member 412a and the second anti-rotation member 412b are not entirely the same, as long as they can lock the locking hook 411. In this embodiment, the first anti-rotation member 412a is configured to rotate along an axis extending in a second horizontal direction, the second anti-rotation member 412b is configured to slide along a first horizontal direction, and the connecting member 43 is configured to slide along the first horizontal direction. Based on this, the second anti-rotation member 412b can be fixed on the connecting member 43 to move with the connecting member 43 in the first horizontal direction. Since the first anti-rotation member 412a is configured to rotate, the first transmission structure 44 needs to be configured to convert the linear motion of the connecting member 43 into the rotational motion of the first anti-rotation member 412a, so that the connecting member 43 can drive the first anti-rotation member 412a and the second anti-rotation member 412b to move when it is moving, thus meeting the structural and functional requirements.

[0032] The specific configuration of the first transmission structure 44 is not limited, as long as it satisfies the transmission between the connecting member 43 and the first anti-rotation member 412a. In this embodiment, the locking component 41 is disposed on the fixed base 2. The first anti-rotation member 412a has an anti-rotation end and a connecting end. The middle part of the first anti-rotation member 412a is rotatably connected to the fixed base 2. The anti-rotation end is used to restrict the lock hook 411 from rotating toward the unlocking position. The first transmission structure 44 includes a first transmission shaft 441 and a first slide groove 442 respectively disposed on the connecting member 43 and the connecting end. The first transmission shaft 441 extends along the second horizontal direction and passes through the first slide groove 442.

[0033] When the connecting member 43 slides along the first horizontal direction, the first drive shaft 441 slides within the first groove 442. The first drive shaft 441 abuts against the groove wall of the first groove 442, pushing the connecting section of the first anti-rotation member 412a to rotate, thereby driving the anti-rotation end to rotate. This converts the linear motion of the connecting member 43 into the rotational motion of the first anti-rotation member 412a. This structural design ensures stable and efficient power transmission, guaranteeing that the first anti-rotation member 412a accurately locks or unlocks the locking hook 411 under the drive of the connecting member 43, thus ensuring the stability and safety of the child safety seat 100 during use. It should be noted that the first slide groove 442 is mainly designed to accommodate the relative displacement relationship between the connecting member 43 and the first anti-rotation member 412a when the linear motion of the connecting member 43 is converted into the rotational motion of the first anti-rotation member 412a. This provides the first transmission shaft 441 with a certain amount of room for movement, preventing the first transmission shaft 441 from jamming and being unable to transmit power when there is relative displacement between the connecting member 43 and the first anti-rotation member 412a.

[0034] In addition, to ensure the stability of the rotation of the first anti-rotation member 412a and to limit the rotation of the first anti-rotation member 412a, the fixed base 2 is also provided with an arc-shaped limiting groove 21. The first transmission shaft 441 extends into the limiting groove 21. The center of the limiting groove 21 coincides with the rotation axis of the first transmission shaft 441, so that when the first transmission shaft 441 moves in the limiting groove 21, it will not be affected by the limiting groove 21. When the first transmission shaft 441 moves to both ends of the limiting groove 21, it will be limited by the limiting groove 21 to limit the maximum rotation stroke of the first anti-rotation member 412a.

[0035] The above describes the specific structural configuration of the locking component 41 on the fixed base 2. Based on this, the driving connection method of the unlocking component 5 and the connecting component 43 will be described in detail below. Specifically, the locking component 41 is located on the fixed base 2 as described above. It is mainly used to lock and unlock the carrier 3 installed on the fixed base 2. Correspondingly, the unlocking component 5 can be synchronously set on the fixed base 2 or set on the base 1. Compared with setting the unlocking component 5 on the fixed base 2, this embodiment sets the unlocking component 5 on the base 1, which can fix the position of the unlocking component 5 and facilitate the unlocking operation. Correspondingly, the unlocking component 5 installed on the base 1 needs to be able to unlock the locking component 41 on the rotatable fixed base 2. In some embodiments, a fixed component is used. The fixed-point unlocking method means that the unlocking component 5 can only be driven to connect with the connecting component 43 on the fixed base 2 when the fixed base 2 is rotated to a fixed point to perform the unlocking operation. With this setting, the drive connection structure 6 between the unlocking component 5 and the connecting component 43 is relatively simple and the fixed-point unlocking is more secure, but the unlocking operation has more restrictions. When the fixed base 2 is not in the unlocking point, the unlocking operation is relatively cumbersome. In this embodiment, a connection structure 6 is provided between the connecting component 43 and the unlocking component 5. The connection structure 6 can maintain the drive connection between the connecting component 43 and the unlocking component 5 when the fixed base 2 rotates. That is, when the fixed base 2 is in any position, the connection structure 6 can drive the connecting component 43 to move when the unlocking component 5 moves, thereby unlocking the lock hook 411. It is applicable to a variety of scenarios and is easy to operate.

[0036] Specifically, in this embodiment, the connector 43 is slidably disposed on the fixed base 2 along the first horizontal direction; the unlocking member 5 is movably disposed on the base 1 along the first horizontal direction; the connecting structure 6 includes a first connector 61 and a second connector 62 respectively connected to the connector 43 and the unlocking member 5. The first connector 61 and the second connector 62 both extend in the vertical direction, and one of them is sleeved on the outside of the other. The first connector 61 can rotate relative to the second connector 62, and the first connector 61 is provided with a first mating part 611, and the second connector 62 is provided with a second mating part 621. The first mating part 611 and the second mating part 621 cooperate so that when the second connector 62 moves downward, it drives the first connector 61 to move downward. That is, in order to allow the fixed base 2 to rotate to any angle while maintaining the driving connection between the unlocking member 5 and the connecting member 43, in this embodiment, the connecting structure 6 is configured as a first connecting member 61 and a second connecting member 62 nested together, so that the first connecting member 61 and the second connecting member 62 can rotate relative to each other. At the same time, the first connecting member 61 and the second connecting member 62 are correspondingly provided with the first mating part 611 and the second mating part 621, so that the first mating part 611 and the second mating part 621 drive to engage in the vertical direction. In this way, no matter what angle the fixed base 2 is located at, the first connecting member 61 and the second connecting member 62 can achieve vertical engagement through the first mating part 611 and the second mating part 621, without affecting the rotation stroke of the fixed base 2, thus meeting the functional requirements.

[0037] It should be noted that when the connecting structure 6 is configured to cooperate between the first connecting member 61 and the second connecting member 62, the movement of the unlocking member 5 in the first horizontal direction needs to be switched to the movement of the connecting structure 6 in the vertical direction, and then switched to the movement of the connecting member 43 in the first horizontal direction. Therefore, this application also proposes that the child safety seat 100 includes a second transmission structure 7 and a third transmission structure 8; wherein, the second transmission structure 7 is disposed between the unlocking member 5 and the second connecting member 62, so that when the unlocking member 5 moves, it drives the second connecting member 62 to move in the vertical direction, thereby driving the first connecting member 61 to move in the vertical direction; the third transmission structure 8 is disposed between the first connecting member 61 and the connecting member 43, so that when the first connecting member 61 moves in the vertical direction, it drives the connecting member 43 to move in the first horizontal direction. This satisfies the structural and functional requirements.

[0038] The specific configuration of the second transmission structure 7 and the third transmission structure 8 is not limited here, as long as they can correspondingly realize the transmission between the unlocking member 5 and the second connecting member 62, and the transmission between the connecting member 43 and the first connecting member 61. In this embodiment, the second transmission structure 7 includes a second transmission shaft 71 and a second slide groove 72 respectively disposed between the unlocking member 5 and the second connecting member 62. The second transmission shaft 71 extends along a second horizontal direction and passes through the second slide groove 72. The third transmission structure 8 includes a third transmission shaft 81 and a third slide groove 82 respectively disposed between the connecting member 43 and the first connecting member 61. The third transmission shaft 81 extends along a second horizontal direction and passes through the third slide groove 82. Both the second transmission structure 7 and the third transmission structure 8 change the transmission path through the cooperation of the slide groove and the transmission shaft. The structure is relatively simple, and it adopts the same mechanism type as the first transmission structure 44, which facilitates the overall structural design and molding.

[0039] Furthermore, to ensure the stability of the locking structure 4, the locking assembly 41 provided on the fixed base 2 further includes a first reset member 45. The first reset member 45 is disposed between the connecting member 43 and the fixed base 2, and is used to provide the connecting member 43 with the driving force to drive the two anti-rotation members 412 to the first position when the two locking hooks 411 switch from the unlocked position to the locked position. Thus, when the carrier 3 is installed so that the locking mating member 42 engages with the locking hooks 411 to drive the locking hooks 411 to switch to the locked position, the locking hooks 411 are not limited. At this time, the first reset member 45 can drive the anti-rotation members 412 to the first position, thereby limiting the locking hooks 411 located in the locked position. Moreover, the first reset member 45 can maintain elasticity, that is, keep the anti-rotation members 412 pressed against the locking hooks 411, maintain the locked state of the locking hooks 411, and ensure the stability of the locking structure 4.

[0040] Specifically, the fixing base 2 is provided with a limiting groove 22 corresponding to the position of the locking hook 411. When the locking hook 411 is in the unlocked position, the opening of the locking hook 411 faces the groove opening of the limiting groove 22, that is, upward, so that the locking fitting 42 can extend into the limiting groove 22, that is, into the locking hook 411. When the locking fitting 42 continues to move down to support the bottom of the groove of the limiting groove 22, the locking fitting 42 drives the locking hook 411 to rotate, so that the locking hook 411 switches to the locked position. At this time, the locking hook 411 rotates until its opening faces the groove wall of the limiting groove 22, thereby closing the groove opening of the limiting groove 22, realizing the limiting of the locking fitting 42, and completing the locking of the bearing 3. It should be noted that when the two locking hooks 411 switch between the locked position and the unlocked position, they rotate in opposite directions. That is, the openings of the two locking hooks 411 face opposite directions in the first horizontal direction. This means that when the support member 3 applies force to the two locking hooks 411 in the horizontal direction, the locking engagement member 42 on the support member 3 will inevitably apply force towards the inside of one of the locking hooks 411, making it difficult to disengage from the locking hook 411 and ensuring locking stability. When unlocking is required, after unlocking the anti-rotation member 412 through the unlocking member 5, the support member 3 can be lifted, which will cause the two locking hooks 411 to rotate in opposite directions until the openings face upwards. This allows the locking engagement member 42 to disengage from the groove of the limiting groove 22 without affecting the disassembly operation of the support member 3.

[0041] Furthermore, the locking structure 4 also includes two second reset members 46, which are correspondingly disposed between the two locking hooks 411 and the fixing seat 2. The second reset members 46 are used to provide the driving force for the locking hooks 411 to move to the unlocked position. That is, the second reset members 46 can maintain the locking hooks 411 without the support member 3 installed in the unlocked position, so that the opening of the locking hook 411 is aligned with the groove of the limiting groove 22 and kept open. This allows the locking structure 4 to be adjusted without adjusting it when the support member 3 is installed. The locking engagement member 42 of the support member 3 is aligned and placed in the limiting groove 22. At this time, the locking engagement member 42 is also located in the opening of the locking hook 411. The support member 3 is pressed down with force, so that the locking engagement member 411... 2. Move down and drive the locking hook 411 to rotate to the locking position. At this time, the locking hook 411 and the limiting groove 22 form a closed space to lock and limit the locking mating part 42. At the same time, the first reset part 45 drives the connecting part 43 to move the anti-rotation part 412 to the first position, that is, to move to the position that restricts the locking hook 411 from rotating toward the unlocking position, thereby completing the locking of the locking mating part 42 on the carrier 3, and thus completing the step of stably installing the carrier 3 onto the fixed base 2.

[0042] It is understood that each of the two locking hooks 411 has at least one first slot 411a on its outer periphery. When the locking hook 411 rotates to the locked position, the opening of the first slot 411a is located on the travel of the anti-rotation member 412. When the anti-rotation member 412 moves to the first position, it extends into the first slot 411a to at least restrict the rotation of the locking hook 411 toward the unlocked position, thus locking the locking hook 411. When the unlocking member 5 drives the anti-rotation member 412 to move out of the first slot 411a, that is, when the anti-rotation member 412 moves from the first position to the second position, the locking hook 411 can rotate. Driven by the second reset member 46, the locking hook 411 automatically rotates to the unlocked position. At this time, the first slot 411a rotates to disengage from the anti-rotation member 411a. During the movement of the 12, the connecting member 43 is driven by the first reset member 45, which automatically drives the anti-rotation member 412 to move from the second position to the first position to approach the locking hook 411. However, at this time, the first anti-rotation member 412a will abut against the outer wall of the locking hook 411 and cannot extend into the first slot 411a, thus it cannot move to the first position, that is, it cannot lock the locking hook 411. Until the bearing member 3 is installed on the fixed base 2 and drives the locking hook 411 to rotate to the locking position, the first slot 411a on the locking hook 411 rotates to the movable part of the first anti-rotation member 412a, so that the anti-rotation force automatically extends into the first slot 411a. When the locking hook 411 rotates to the locking position, the anti-rotation locking of the locking hook 411 is automatically completed, ensuring the stability of the locking.

[0043] In addition, a second slot 411b is provided on the outer periphery of the locking hook 411. When the locking hook 411 rotates to the unlocking position, the second slot 411b is located on the active stroke of the anti-rotation member 412. That is, when the anti-rotation member 412 is in the second position, the anti-rotation member 412 extends into the second slot 411b, thereby restricting the locking hook 411 from continuing to rotate in a direction away from the locking position, so as to limit the locking hook 411 and prevent the locking hook 411 from rotating excessively, causing the opening of the locking hook 411 to be misaligned with the groove of the limiting groove 22, so that the locking mating member 42 on the bearing member 3 cannot be installed normally.

[0044] Specifically, the anti-rotation member 412 is driven by the first reset member 45 to press against the outer periphery of the locking hook 411. During the locking process, that is, during the process of the locking hook 411 rotating to the locked position, the anti-rotation member 412 moves closely against the outer periphery of the locking hook 411. When the locking hook 411 rotates to the locked position, the first slot 411a is exposed on the moving stroke of the anti-rotation member 412. The anti-rotation member 412 extends into the first slot 411a to complete the locking of the locking hook 411. Conversely, during the unlocking process, the unlocking component 5 drives the anti-rotation component 412 to disengage from the first slot 411a. At this time, the locking hook 411 can rotate toward the unlocking position until it rotates to the point where the first slot 411a is disengaged from the active stroke of the anti-rotation component 412. This releases the operation of the unlocking component 5. At this time, the first reset component 45 drives the connecting component 43 to move the anti-rotation component 412 against the outer periphery of the locking hook 411 until the locking hook 411 rotates to the unlocking position. The anti-rotation component 412 then extends into the second slot 411b, completing the locking and limiting of the locking hook 411. At this time, the elastic force of the first reset component 45 and the second reset component 46 is used to drive the anti-rotation component 412 and the locking hook 411 to abut against each other, preventing loosening and noise.

[0045] In addition, to visually display the status of the locking hook 411, this application also provides an indicator to show whether the locking hook 411 is in the locked position or the unlocked position. In this way, on the one hand, after the installation of the carrier 3 is completed, the user can visually determine whether the locking hook 411 is correctly locked; on the other hand, before the installation of the carrier 3, the user can visually determine whether the locking hook 411 is in the unlocked position waiting to be locked, which facilitates the installation of the carrier 3.
