Description

Technical Field

[0001] This application relates to the field of child safety seat technology, and more specifically, to a child safety seat with rotation and sliding functions. Background Technology

[0002] A car child safety seat, also known as a Child Restraint System (CRS), is a seat designed specifically for children of different ages (or weights), installed in a car, and effectively improves the safety of children while riding in a vehicle.

[0003] Specifically, a child safety seat consists of two parts: the seat body and the base. The two parts are rotatably connected, which makes it easy to place the child in the seat body or to take the child out of the seat body.

[0004] Furthermore, when the seat body is rotated and adjusted to reach a preset rotation position relative to the base, the seat body needs to be fixed relative to the base to prevent the seat body from rotating relative to the base during vehicle operation, which could negatively impact the user experience of children sitting in the seat.

[0005] However, the relevant technology has at least one of the following problems: since the seat body is usually fixed relative to the base by screw connection, and the actual application environment of child safety seats is a dynamic environment, the threaded connection is prone to loosening, reducing the reliability of the fixation between the seat body and the base. Utility Model Content

[0006] The technical problem addressed by this application is that the method of fixing the seat body relative to the base is usually a screw connection. However, given that the actual application environment of child safety seats is a dynamic one, the screw connection is prone to loosening, reducing the reliability of the fixation between the seat body and the base.

[0007] To address the aforementioned issues, this application provides a child safety seat with rotation and sliding functions. The child safety seat includes: a seat body with a receiving space; a base and a rotating disc assembly that cooperate with each other, wherein the seat body rotates with the base via the rotating disc assembly; and an actuating element movably disposed on the rotating disc assembly for adjusting the transition of a locking assembly disposed on the rotating disc assembly relative to the base between an unlocked state and a locked state; wherein, when the locking assembly is in the locked state, it restricts the rotation of the rotating disc assembly relative to the base; and when the locking assembly is in the unlocked state, it allows the rotating disc assembly to rotate relative to the base.

[0008] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: through the linkage between the toggle component and the locking assembly, the seat body can flexibly switch between rotating or restricting rotation relative to the base. Specifically, by setting the locking assembly to replace the conventional screw fixing method, the instability caused by loose screws in the locked state is effectively avoided. Specifically, the seat body cannot maintain an effective fixed state relative to the base, resulting in rotation.

[0009] In one example of this application, the toggle element and the rotary disk assembly are rotatably connected.

[0010] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: the toggle component and the rotating disk assembly are rotatably connected, which facilitates user operation and reduces the difficulty of operation.

[0011] In one embodiment of this application, the base is provided with a mounting groove for assembling a rotating disk assembly, and the base is also provided with at least one snap-fit ​​groove communicating with the mounting groove; the locking assembly includes a snap-fit ​​block and an elastic element that cooperate with each other: the elastic element and the snap-fit ​​block are disposed in a receiving groove of the rotating disk assembly, the elastic element is disposed at the end of the snap-fit ​​block away from the snap-fit ​​groove, and the elastic element has an elastic force that applies to the snap-fit ​​block to extend it out of the receiving groove; wherein, when the snap-fit ​​block extends from the receiving groove into the snap-fit ​​groove, it restricts the rotation of the rotating disk assembly relative to the base; when the locking assembly is in the unlocked state, the snap-fit ​​block is received in the receiving groove.

[0012] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting up elastic elements, the stability of the locking block being pressed into the locking groove is improved, and the risk of it coming out of the locking groove is reduced.

[0013] In one embodiment of this application, the rotating disk assembly includes a rotating disk mounted in a mounting groove; the locking assembly further includes a zipper disposed in a limiting groove of the rotating disk, one end of the zipper being connected to a toggle member, and the other end being connected to the end of the locking block away from the locking groove; wherein, when the toggle member is adjusted to be in a first relative position relative to the rotating disk assembly, the zipper member pulls the locking block to maintain it in the receiving groove; when the toggle member is released, the locking block is subjected to elastic force to enter the locking groove or has a tendency to extend out of the receiving groove.

[0014] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the efficiency of the action of the actuating component on the locking block is realized through the zipper component, and the switching between the unlocked and locked states is flexibly realized. For example, the zipper component is an elastic rope with elastic properties.

[0015] In one embodiment of this application, the base includes a top cover, a body, and a rotating locking member; the top cover covers the upper end of the body and has a first inner ring structure for accommodating a rotating disk assembly; the rotating locking member is disposed within the accommodating space of the body and is supported by a plurality of support rods; the rotating disk assembly is fitted onto the second inner ring structure of the rotating locking member; wherein, a snap-fit ​​groove is formed in the second inner ring structure.

[0016] In one embodiment of this application, the rotating disk assembly further includes a pressure plate, which covers the side of the rotating disk near the seat body, and the pressure plate has a toggle travel groove at the position corresponding to the limiting groove; the toggle member includes a toggle body, a rotating shaft, and a transmission part; the toggle body is located on the side of the pressure plate near the seat body; the rotating shaft is located on the side of the toggle body away from the seat body, and passes through the first shaft hole in the pressure plate and the second shaft hole in the rotating disk in sequence; the transmission part is located on the side of the toggle body away from the seat body, and extends into the toggle travel groove and the limiting groove in sequence for connection with the zipper.

[0017] In one embodiment of this application, the base is provided with multiple rotation limit buckles, which are arranged in the circumferential position of the rotating disk assembly; the rotating disk assembly is set on a limiting platform composed of multiple rotation limit buckles to limit the movement of the rotating disk assembly along a direction deviating from its rotation trajectory.

[0018] Compared with existing technologies, the technical effects achieved by this solution are as follows: on the one hand, the limiting platform supports the rotating disk assembly; on the other hand, by combining the relative positions of multiple rotating limiting buckles to the rotating disk assembly, the stability of the rotating disk assembly during rotation is improved. In other words, by limiting its movement that deviates from its rotation trajectory, the risk of discomfort caused to the user sitting in the seat body by the rotating disk assembly deflecting relative to the base, such as wobbling, is reduced.

[0019] In one example of this application, the child safety seat includes: a push-pull assembly that cooperates with a rotating disc assembly and is located between the rotating disc assembly and the seat body; wherein the push-pull assembly is used to drive the seat body to move relative to the base.

[0020] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting up a push-pull component, the seat body can move relative to the base through the push-pull component, and combined with the rotating disc component, it can rotate relative to the base. Thus, when using the child safety seat, it can be freely rotated at an angle according to the child's needs, and can also be moved laterally, so that the seat body can be sent out in a direction away from the base, which facilitates the placement and removal of the child, meets the safety requirements of children riding in cars, improves the convenience of use, and makes it easier for users to use.

[0021] In one embodiment of this application, the push-pull assembly includes: a ball slider slidably disposed within a first groove of the rotary disk assembly; and a push-pull support plate disposed on the side of the ball slider away from the rotary disk assembly, wherein the push-pull support plate is provided with a second groove for the ball slider to slide along, so that the ball slider slides relative to the push-pull support plate along the second groove.

[0022] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: Specifically, multiple rolling balls are provided on the side of the ball slider that contacts the first slide groove. The multiple rolling balls slide in the first slide groove to drive the ball slider to slide relative to each other. By optimizing the contact interface between the rolling slider and the first slide groove, the friction between them is effectively reduced, thereby significantly improving the responsiveness and operating efficiency of the seat body, and ensuring the smoothness and immediacy of the operation of the seat body.

[0023] In one embodiment of this application, either the first slide groove or the ball slider is provided with a ridge, and the other is provided with a groove; the ball slider is provided with at least one protrusion on the side away from the first slide groove, the protrusion being used to slide within the second slide groove.

[0024] Compared with existing technologies, the technical effect achieved by adopting this technical solution is to improve the sliding stability between the ball block and the push-pull support plate.

[0025] By adopting the technical solution of this application, the following technical effects can be achieved: (1) Through the linkage between the toggle and the locking assembly, the seat body can be flexibly rotated or restricted from rotating relative to the base. Specifically, by setting the locking assembly to replace the conventional screw fixing method, the instability caused by the loosening of the screw in the locked state is effectively avoided. Specifically, the seat body cannot maintain an effective fixed state relative to the base, resulting in rotation. (2) By setting the elastic element, the stability of the snap block is improved and the risk of it coming out of the snap block is reduced; (3) By setting the push-pull component, the seat body can move relative to the base through the push-pull component. Combined with the rotating disk component, it can rotate relative to the base. Thus, when using the child safety seat, it can be rotated freely according to the child's needs, and it can also be moved laterally. This allows the seat body to be sent out in a direction away from the base, making it easier to place and carry the child. This meets the safety requirements for children riding in the car, improves the ease of use, and makes it more convenient for users. Attached Figure Description

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 This is a structural schematic diagram of a child safety seat 100 with rotation and sliding functions provided in an embodiment of this application, combined with... Figures 2-13 The child safety seat 100 includes, for example, a seat body 10, a rotating disc assembly 31 30, a base 20, and an actuating element 40. Specifically, the seat body 10 has a receiving space; the base 20 and the rotating disc assembly 31 30 cooperate with each other, and the seat body 10 achieves rotational engagement with the base 20 through the rotating disc assembly 31 30; the actuating element 40 is movably disposed on the rotating disc assembly 31 30 and is used to adjust the locking assembly 50 disposed on the rotating disc assembly 31 30 relative to the base 20 between an unlocked state and a locked state; wherein, when the locking assembly 50 is in the locked state, it restricts the rotation of the rotating disc assembly 31 30 relative to the base 20; when the locking assembly 50 is in the unlocked state, it allows the rotating disc assembly 31 30 to rotate relative to the base 20.

[0030] Through the linkage between the actuating element 40 and the locking assembly 50, the seat body 10 can be flexibly rotated or restricted from rotating relative to the base 20. Specifically, by setting the locking assembly 50 to replace the conventional screw connection fixing method, the instability caused by the loosening of the screw connection in the locked state is effectively avoided. Specifically, the seat body 10 cannot maintain an effective fixed state relative to the base 20, resulting in rotation.

[0031] Preferably, the actuating member 40 and the rotating disk 31 assembly 30 are rotatably connected.

[0032] Preferably, the base 20 is provided with a mounting groove for assembling the rotating disk 31 assembly 30, and the base 20 is also provided with at least one snap-fit ​​groove 21 communicating with the mounting groove; the locking assembly 50 includes a snap-fit ​​block 51 and an elastic member 52 that cooperate with each other: the elastic member 52 and the snap-fit ​​block 51 are disposed in the receiving groove 311 of the rotating disk 31 assembly 30, the elastic member 52 is disposed at the end of the snap-fit ​​block 51 away from the snap-fit ​​groove 21, and the elastic member 52 has an elastic force that applies to the snap-fit ​​block 51 to extend it out of the receiving groove 311; wherein, when the snap-fit ​​block 51 extends from the receiving groove 311 into the snap-fit ​​groove 21, it restricts the rotation of the rotating disk 31 assembly 30 relative to the base 20; when the locking assembly 50 is in the unlocked state, the snap-fit ​​block 51 is received in the receiving groove 311.

[0033] Preferably, the rotating disk 31 assembly 30 includes a rotating disk 31 mounted in the mounting groove; the locking assembly 50 also includes a zipper disposed in the limiting groove 312 of the rotating disk 31, one end of the zipper is connected to the actuating member 40, and the other end is connected to the end of the locking block 51 away from the locking groove 21; wherein, when the actuating member 40 is in a first relative position relative to the rotating disk 31 assembly 30, the zipper pulls the locking block 51 to be held in the receiving groove 311; when the actuating member 40 is released, the locking block 51 is subjected to elastic force to enter the locking groove 21 or has a tendency to extend out of the receiving groove 311.

[0034] Preferably, the base 20 includes an upper cover 22, a body 23, and a rotary locking member 24; the upper cover 22 covers the upper end of the body 23, and the upper cover 22 is provided with a first inner ring structure 221 for accommodating the rotating disk 31 assembly 30; the rotary locking member 24 is disposed within the accommodating space of the body 23, and is supported by a plurality of support rods; the rotating disk 31 assembly 30 is sleeved on the second inner ring structure 241 of the rotary locking member 24; wherein, a snap-fit ​​groove 21 is formed in the second inner ring structure 241. For example, the rotary locking member 24 is an annular structure, which is mounted to the rotating disk 31 by a connecting plate. Specifically, the annular structure is disposed in the fitting gap formed between the connecting plate and the rotating disk 31, and the connecting plate and the rotating disk 31 are, for example, screwed together.

[0035] Preferably, the rotating disk 31 assembly 30 further includes a pressure plate 32, which covers the side of the rotating disk 31 near the seat body 10, and the pressure plate 32 is provided with a toggle stroke groove 321 at the position corresponding to the limiting groove 312; the toggle member 40 includes a toggle body part 41, a rotating shaft part 42 and a transmission part 43.

[0036] Furthermore, the actuating body 41 is located on the side of the pressure plate 32 near the seat body 10; the rotating shaft 42 is located on the side of the actuating body 41 away from the seat body 10, and passes through the first shaft hole in the pressure plate 32 and the second shaft hole in the rotating disk 31 in sequence; the transmission part 43 is located on the side of the actuating body 41 away from the seat body 10, and the transmission part 43 extends into the actuating stroke groove 321 and the limiting groove 312 in sequence for connection with the zipper.

[0037] In one specific example, the locking assembly 50 may also include a release block 53 disposed on the side of the pressure plate 32 away from the actuating member 40. Specifically, the release block 53 has a transmission stroke groove 531 and a cord locking hole 532 at the end near the actuating member 40. The release block 53 is disposed at the end of the limiting groove 312 away from the receiving groove 311, and the transmission part 43 is disposed in the transmission stroke groove 531. The zipper is, for example, an elastic cord, so one end of the elastic cord extends into the cord locking hole 532, and the other end of the elastic cord is connected to the locking block 51, and the two are engaged, for example, in a locking fit. Therefore, during the rotation of the actuating member 40, the drive release block 53 moves within the travel trajectory defined by the limiting groove 312, thereby pulling the elastic rope to drive the locking block 51 located at the other end of the elastic rope. For example, a pulling force is applied to the locking block 51 to disengage it from the corresponding locking groove 21. Furthermore, when the driving force on the actuating member 40 is removed, the elastic force of the elastic member 52 and the elastic rope respectively drives each component to return to its initial position.

[0038] Preferably, the base 20 is provided with a rotation limit buckle 60; the rotation limit buckle 60 is located in the circumferential position of the rotating disk 31 assembly 30 and cooperates with the rotating disk 31 assembly 30 to limit the movement of the rotating disk 31 assembly 30 along a direction deviating from its rotation trajectory.

[0039] Preferably, the child safety seat 100 includes, for example, a push-pull assembly 70, which cooperates with the rotating disk 31 assembly 30 and is located between the rotating disk 31 assembly 30 and the seat body 10; wherein, the push-pull assembly 70 is used to drive the seat body 10 to move relative to the base 20.

[0040] Specifically, the existing child safety seat 100's backrest angle adjustment device generally adjusts the angle between the seat and the base 20 through an angle adjustment handle. The angle adjustment handle is usually hidden inside the seat and is not easy for the operator to adjust, especially after getting out of the car, when adjusting from the side of the safety seat to rotate the safety seat to the side. Therefore, there are inconveniences in both the process of putting the child into the safety seat and taking the child out of the safety seat.

[0041] Therefore, to solve the above problems, the child safety seat 100 with rotation and sliding functions provided in this application embodiment is equipped with a push-pull assembly 70 so that the seat body 10 can move relative to the base 20 through the push-pull assembly 70. Combined with the rotating disk 31 assembly 30, which can rotate relative to the base 20, when using the child safety seat 100, it can be freely rotated at an angle according to the child's usage needs, and can also be laterally moved, so that the seat body 10 can be sent out in a direction away from the base 20, thereby facilitating the placement and removal of the child, meeting the safety requirements of children riding in the car, improving the convenience of use, and making it convenient for users.

[0042] Preferably, the push-pull assembly 70 includes, for example, a ball slider 71 and a push-pull support plate 72. The ball slider 71 is slidably disposed in a first groove of the rotary disk 31 assembly 30; the push-pull support plate 72 is disposed on the side of the ball slider 71 away from the rotary disk 31 assembly 30, and the push-pull support plate 72 is provided with a second groove for the ball slider 71 to slide, so that the ball slider 71 slides relative to the push-pull support plate 72 along the second groove.

[0043] Specifically, a two-stage sliding mechanism is formed between the push-pull assembly 70, the ball slider 71, and the rotating disk 31 body. The ball slider 71 is placed in the first groove on the rotating disk 31 body and can slide a certain distance within the rotating disk 31 body. At the same time, the ball slider 71 is also engaged in the second groove of the push-pull assembly 70, and the push-pull assembly 70 can slide relative to the ball slider 71, thus forming a two-stage sliding mechanism. The sliding stroke of the push-pull assembly 70 relative to the ball slider 71 is twice the sliding stroke of the ball slider 71 relative to the rotating disk 31.

[0044] Furthermore, either the first slide groove or the ball slider 71 is provided with a protrusion, and the other is provided with a groove; the ball slider 71 is provided with at least one protrusion on the side away from the first slide groove, the protrusion being used to slide within the second slide groove.

[0045] For example, in some embodiments, a protrusion is provided in the first groove, and a groove is provided on the ball slider 71. In other embodiments, a groove is provided in the first groove, and a protrusion is provided on the ball slider 71.

[0046] In some embodiments, a plurality of rolling balls are provided on the side of the ball slider 71 that contacts the first slide groove. The ball slider 71 slides relative to the first slide groove by the sliding of the plurality of rolling balls. By optimizing the contact interface between the rolling slider and the first slide groove, the friction between them is effectively reduced, thereby significantly improving the responsiveness and operating efficiency of the seat body 10, and ensuring the smoothness and immediacy of the operation of the seat body 10.

[0047] While this application discloses the above information, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this application; therefore, the scope of protection of this application shall be determined by the scope defined in the claims.
