Description

Technical Field

[0001] This utility model relates to a car seat specifically designed for vehicles to improve the safety of children while riding, and more specifically to a car child safety seat. Background Technology

[0002] As living standards improve, more and more people are choosing to install child safety seats in their cars to ensure their children's safety while riding. Most child safety seats nowadays have the functions of rotation and fore-aft tilt adjustment to increase the comfort of children.

[0003] In the prior art, a Chinese utility model patent with patent number ZL202323088961.6 (publication number CN220904764U) entitled "A Child Safety Seat 360-degree Rotation and Orientation Mechanism" discloses a child safety seat that can rotate and tilt. The base assembly is provided with a rotating assembly that can rotate relative to the base assembly. The seat body rotates together with the rotating assembly. The tilt angle is adjusted between the rotating assembly and the seat body through a sliding fit between a strip guide hole and a connecting shaft.

[0004] Child safety seats typically consist of a seat back and a seat body. When a child is seated, their upper body rests against the seat back, resulting in pressure on the backrest from the child's backward movement. The seat back is also designed to tilt backward to accommodate the child's posture. Before the seat body rotates, the entire seat body is stable due to the rotation locking mechanism. However, when the rotating disc and seat body need to be rotated, the rotation locking mechanism must be unlocked. During rotation, the weight of the seat body and the child on it inevitably causes the seat back to experience radial outward pressure along the rotating disc. This pressure can easily cause the seat body to tilt outward, and this pressure also acts on the connection structure between the seat body and the rotating disc (such as a gear shift lever). Over time, this can lead to fatigue and bending of the connection structure, increasing the risk of the seat body detaching from the rotating disc, resulting in poor safety. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a car child safety seat that prevents the seat body from tilting outward during rotation and improves the safety of the connection structure between the seat body and the rotating disc, in light of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the car child safety seat includes:

[0007] Base;

[0008] A rotating disk is rotatably connected within the base and can rotate around a rotation axis.

[0009] The seat body includes a seat and a seat back that is connected to the rear side of the seat and extends upward. The seat is mounted on and connected to the rotating disk. The seat body can drive the rotating disk to rotate around the rotating axis.

[0010] The feature is that: a connecting bracket is fixedly connected to the rotating disk, the connecting bracket having a first connecting member connected to the surface of the rotating disk, and a second connecting member connected to the rear side of the first connecting member and extending upward at an incline, the second connecting member being connected to the seat back to support the seat back, or / partially or entirely embedded in the seat back to support the seat back.

[0011] To further enhance the stability of the seat body during rotation, the rear side of the seat back is recessed with a groove for the second connector to be embedded, the bottom of which contacts the second connector. This groove facilitates the manufacturer's positioning and installation of the connecting bracket. The contact between the bottom of the groove and the second connector allows the connecting bracket to withstand the backward pressure from the seat back and the child. Simultaneously, the second connector embedded in the groove restricts the circumferential rotation of the seat back relative to the second connector, ensuring the seat body remains stationary relative to the connecting bracket during rotation. This ensures the connecting bracket consistently supports the seat back during rotational adjustments. Furthermore, the second connector can slide directly along the groove, with its front side fitting and sliding against the bottom of the groove. This design provides a larger contact area and eliminates the need for a traditional tilt adjustment structure.

[0012] To extend the service life of the seat back, the second connector is further tilted at the same angle as the seat back. This technical solution ensures that the second connector and the seat back are arranged parallel to each other, preventing interference and scratches to the seat back during assembly and rotation of the seat back and the second connector.

[0013] To facilitate user adjustment of the seat's tilt angle, the rear side of the seat back is further provided with a sliding groove that is angled forward and backward. The second connector has a connecting rod that slides into the sliding groove. The engagement of the connecting rod and the sliding groove allows the seat back to be tilted relative to the connecting bracket. Simultaneously, during the sliding process, the mating surface between the connecting rod and the sliding groove also distributes the pressure from the seat back and the child's backward movement, further enhancing stability.

[0014] To further enhance the stability of the seat body during rotation, two sets of sliding grooves are symmetrically distributed on both sides of the second connector, with each end of the connecting rod engaging one of the two sets of sliding grooves. The engagement of the two ends of the connecting rod into the two sets of sliding grooves restricts the movement of the connecting rod perpendicular to the rotation axis, thereby limiting the circumferential rotation of the seat body relative to the connecting bracket.

[0015] To enhance the load-bearing capacity of the connecting bracket, the base is further defined as an L-shaped base with a backrest, and a connecting structure is provided between the second connecting member and the front side of the backrest. This connecting structure strengthens the connection between the base and the second connecting member, allowing the backrest to share the pressure on the second connecting member. Simultaneously, since the second connecting member is connected to the seat back, the connecting structure also indirectly connects the backrest and the seat back, preventing the base from separating from the seat body due to forward tilting in certain postures. This improves the safety of children riding in the seat and offers the advantage of "dual-purpose functionality."

[0016] In order for the connection structure to accommodate the rotational movement of the seat body relative to the base, the connection structure further includes:

[0017] The first connecting hook is fixedly installed on the front side of the base backrest;

[0018] The second connecting hook is fixedly disposed at the upper end of the second connecting member. It is connected to the first connecting hook in the front-to-back direction at an upper limit, and is movable relative to the first connecting hook in the rotation direction of the rotating disk. This allows the first connecting hook and the second connecting hook to disengage when the connecting bracket rotates relative to the base. When the seat body is in a forward-facing posture, the first connecting hook and the second connecting hook are connected in the front-to-back direction at an upper limit to prevent forward tilting. When the seat body is rotating relative to the base, the first connecting hook and the second connecting hook disengage, so that the rotational movement of the seat body is not restricted by the connecting structure.

[0019] Furthermore, the first connecting hook has a first through groove formed on both sides perpendicular to the rotation direction for the second connecting hook to rotate out, and the second connecting hook has a second through groove formed on both sides perpendicular to the rotation direction for the first connecting hook to rotate out.

[0020] To facilitate user adjustment of the seat body by rotation, the front side of the base backrest is further provided with a relief groove corresponding to the second connecting hook. This relief groove is used to prevent the second connecting hook from rotating relative to the base. The relief groove design avoids interference between the second connecting hook and the base backrest during rotation adjustment.

[0021] To facilitate user adjustment of the rotation angle of the rotating disk, the outer surface of the rotating disk is further provided with at least two recessed slots spaced apart circumferentially. The base is provided with a rotation limiting component for restricting the rotation position of the rotating disk, the rotation limiting component including:

[0022] A locking pin is slidably disposed on the base along the radial direction of the rotating disk. One radially outward end of the locking pin has a handle for applying external force, and the other radially inward end protrudes to form a locking pin. The locking pin can be engaged in a slot and disposed opposite to it.

[0023] A compression spring, located between the base and the locking pin, tends to press the locking pin radially inward along the radius of the rotating disk. The user pulls the locking pin outward by the handle, disengaging it from the slot. The compression spring compresses, and when the rotating disk rotates to align with the locking pin in another slot, the user releases the locking pin. The compression spring then pushes the locking pin radially inward to reset it, and the locking pin engages in the other slot.

[0024] Compared with the prior art, the advantages of this utility model are as follows: The child safety seat of this utility model supports the seat back while rotating by fixing a bracket on the rotating plate, which avoids the phenomenon of the seat itself tilting outward due to the change of the center of gravity of the seat body and the child and the centrifugal force after rotation. At the same time, it protects other structures used to connect the seat body and the rotating plate, making the seat body more stable during rotation and improving the safety of children riding.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] like Figures 1-7 The image shown is a preferred embodiment of this utility model. This car child safety seat is primarily used to ensure the safety of children riding in a car. When the child safety seat needs to be rotated and its tilt angle adjusted, the center of gravity of the seat body and the child may fall outside the rotating disc within a certain range, causing the seat to tilt outwards and increasing the risk of the seat body falling off. Therefore, it would be beneficial to provide a car child safety seat that can prevent the seat body from tilting outwards and has higher safety. The structure of the car child safety seat in this embodiment will be described in detail below:

[0035] See Figures 1 to 3 The car child safety seat of this embodiment includes a base 1, a rotating disk 2, and a seat body 3. The rotating disk 2 is rotatably connected to the base 1 and can rotate around the rotating axis a. The seat body 3 includes a seat 31 and a seat back 32 connected to the rear side of the seat 31 and extending upward. The seat 31 is disposed on the rotating disk 2 and connected to the rotating disk 2. The seat body 3 can drive the rotating disk 2 to rotate around the rotating axis a. A connecting bracket 4 is also fixedly connected to the rotating disk 2. The connecting bracket 4 has a first connecting member 41 connected to the surface of the rotating disk 2 and a second connecting member 42 connected to the rear side of the first connecting member 41 and extending upward. The second connecting member 42 is connected to the seat back 32 to support the seat back 32.

[0036] See Figure 4 The rear side of the seat backrest 32 is recessed with a groove 321 for the second connector 42 to be fitted into, and the bottom of the groove 321 contacts the second connector 42. The groove 321 facilitates the manufacturer's positioning and installation of the connecting bracket 4. The contact between the bottom of the groove 321 and the second connector 42 allows the connecting bracket 4 to withstand the backward pressure of the seat backrest 32 and the child. At the same time, the second connector 42, fitted into the groove 321, also restricts the circumferential rotational movement of the seat backrest 32 relative to the second connector 42, so that the seat body 3 can remain stationary relative to the connecting bracket 4 when rotating. This ensures that the connecting bracket 4 can always support the seat backrest 32 during rotation adjustment, further increasing the stability of the seat body 3 during rotation.

[0037] See Figure 3 The tilt angle of the second connector 42 is the same as the tilt angle of the seat back 32. This technical solution ensures that the second connector 42 and the seat back 32 are arranged parallel to each other, preventing interference and wear on the seat back 32 during assembly and rotation, thus extending the service life of the seat back 32.

[0038] See Figure 4 The rear side of the seat backrest 32 is provided with a sliding groove 322 that is inclined forward and backward. The second connecting member 42 is provided with a connecting rod 43 that slides and engages with the sliding groove 322. The engagement between the connecting rod 43 and the sliding groove 322 allows the seat backrest 32 to be tilted relative to the connecting bracket 4. At the same time, during the sliding process, the mating surface between the connecting rod 43 and the sliding groove 322 also shares the pressure of the seat backrest 32 and the child's backward movement, further enhancing stability and facilitating the user to adjust the tilt angle of the seat body 3.

[0039] Two sets of sliding grooves 322 are provided and symmetrically distributed on both sides of the second connector 42. The two ends of the connecting rod 43 are respectively inserted into the two sets of sliding grooves 322. The sliding grooves 322 restrict the movement of the connecting rod 43 perpendicular to the rotation axis a, thereby restricting the circumferential rotation of the seat body 3 relative to the connecting bracket 4, and further increasing the stability of the seat body 3 during rotation.

[0040] See Figure 5 The base 1 is an L-shaped base with a base backrest 11. A connecting structure 5 is provided between the second connector 42 and the front side of the base backrest 11. The connection structure 5 enhances the connection between the base 1 and the second connector 42, allowing the base backrest 11 to share the pressure on the second connector 42. At the same time, since the second connector 42 is connected to the seat backrest 32, the connecting structure 5 also indirectly connects the base backrest 11 and the seat backrest 32, preventing the base 1 from separating from the seat body 3 due to forward tilting under certain postures. It also enhances the load-bearing capacity of the connecting bracket 4, improves the safety of children riding, and has the advantage of "two uses in one".

[0041] See Figure 5 and Figure 6 The connecting structure 5 includes a first connecting hook 51 and a second connecting hook 52. The first connecting hook 51 is fixedly disposed on the front side of the base backrest 11, and the second connecting hook 52 is fixedly disposed on the upper end of the second connecting member 42. The first connecting hook 51 is connected to the first connecting hook 51 in the front-back direction, and is movable relative to the first connecting hook 51 in the rotation direction along the rotating disk 2. This allows the first connecting hook 51 and the second connecting hook 52 to disengage when the connecting bracket 4 rotates relative to the base 1. When the seat body 3 is in a forward-facing posture, the first connecting hook 51 and the second connecting hook 52 are connected in the front-back direction to prevent forward tilting. When the seat body 3 rotates relative to the base 1, the first connecting hook 51 and the second connecting hook 52 disengage, allowing the rotational movement of the seat body 3 to be unrestricted by the connecting structure 5. This enables the connecting structure 5 to adapt to the rotational movement of the seat body 3 relative to the base 1.

[0042] The first connecting hook 51 has a first through groove 510 formed on both sides perpendicular to the rotation direction for the second connecting hook 52 to rotate out of it. The second connecting hook 52 has a second through groove 520 formed on both sides perpendicular to the rotation direction for the first connecting hook 51 to rotate out of it. The front side of the base backrest 11 has a recessed relief groove 111 corresponding to the second connecting hook 52. The relief groove 111 is used to avoid the rotational movement of the second connecting hook 52 relative to the base 1. The design of the relief groove 111 can prevent interference between the second connecting hook 52 and the base backrest 11 during rotational adjustment, facilitating the user's rotational adjustment of the seat body 3.

[0043] See Figure 3 and Figure 7 The outer side of the rotating disk 2 is provided with at least two recessed slots 21 at intervals around the periphery. The base 1 is provided with a rotation limiting component 6 for limiting the rotation position of the rotating disk 2. The rotation limiting component 6 includes a locking pin 61 and a compression spring 62. The locking pin 61 is slidably disposed on the base 1 along the radial direction of the rotating disk 2. One radially outward end of the locking pin 61 forms a handle portion 611 for applying external force, and the other radially inward end protrudes to form a locking pin portion 612. The locking pin portion 612 can be engaged with the slots 21 and disposed opposite to each other. The compression spring 62 is disposed between the base 1 and the locking pin 61 and has a tendency to press the locking pin 61 radially inward along the radial direction of the rotating disk 2. The user pulls the locking pin 61 outward by the handle 611, causing the locking pin 612 to disengage from the slot 21. The compression spring 62 is compressed. When the rotating disk 2 rotates to the point where the other slot 21 is aligned with the locking pin 612, the user releases the locking pin 61. The compression spring 62 pushes the locking pin 61 radially inward to reset it, and the locking pin 612 engages with the other slot 21, making it convenient for the user to adjust the rotation angle of the rotating disk 2.

[0044] The working principle of the car child safety seat in this embodiment is as follows:

[0045] 1) Static: When the seat body 3 is in a forward-facing position, the connecting bracket 4 supports the seat back 32, and the first connecting hook 51 and the second connecting hook 52 are connected in a front-to-back limiting manner to prevent the seat body 3 from tilting forward and to allow the seat back 32 to share the force of the connecting bracket 4.

[0046] 2) Rotation adjustment: When the user pulls the handle 611 outward, the locking part 612 of the locking pin 61 disengages from the slot 21. At the same time, the seat body 3 is moved so that the seat body 3 and the rotating disk 2 rotate around the rotation axis a. During the rotation, the connecting bracket 4 remains stationary relative to the seat back 32. The connecting bracket 4 bears the pressure of the seat back 32 and the child backward through the contact surface between the groove 321 and the second connecting part 42, and the cooperation between the slide groove 322 and the connecting rod 43, so as to prevent the seat body 3 from tilting backward during the rotation and improve the safety of the child.

[0047] Example 2: Child safety seat with second connector slidingly fitted into groove

[0048] The structure of the car child safety seat in this embodiment is basically the same as that in Embodiment 1, except that: part or all of the second connecting member 42 is embedded in the seat back 32 to support the seat back 32. The second connecting member 42 can slide directly along the groove 321, that is, the front side of the second connecting member 42 is in contact with the bottom surface of the groove 321 and slides. In this solution, the contact surface is larger and the traditional recline angle adjustment structure can be eliminated, that is, the sliding engagement structure of the groove 322 and the connecting rod 43 in Embodiment 1. The width of the groove 321 is adapted to the width of the second connecting member 321 to limit the circumferential rotation of the seat body 3 relative to the connecting bracket 4, making the seat body 3 more stable during rotation adjustment.
