Base device and child safety seat

Abstract

Disclosed in the present application are a base device and a child safety seat. An arc surface is arranged on a base, and the arc surface is located on the front side of a mounting cavity for rotatably arranging a translation assembly, such that when the angle of a seat is adjusted, a sufficient amount of space is reserved between an arc-shaped area at the bottom of the seat and the arc surface, and the back of a hand does not easily touch the base, thereby reducing the risk of scratching. In addition, the translation assembly can drive the seat to translate; therefore, multi-angle translation of the seat can be realized when the translation assembly rotates to different angles relative to the base, alleviating the problem of the translation distance being limited due to different door opening angles of different vehicle models, ensuring the translation distance, and facilitating children getting on and off the seat.

Description

Base unit and child safety seat Technical Field

[0001] This application relates to the field of maternal and infant products technology, and in particular to a base device and a child safety seat. Background Technology

[0002] A child safety seat is a seat specifically designed for children of different weights (or age groups) and installed in a car to effectively improve children's safety while traveling. For example, in the event of emergency braking or a forward collision, a child safety seat can reduce the impact force on the child and effectively prevent the child's body from moving forward rapidly, thus avoiding secondary collisions.

[0003] Currently, child safety seats can rotate relative to the base. However, when adjusting the seat angle, the back of the hand may touch the base, which can easily cause abrasions. Utility Model Content

[0004] The purpose of this application is to provide a base device and a child safety seat in which the back of the hand is less likely to touch the base, thereby reducing the risk of abrasions.

[0005] The embodiments of this application can be implemented as follows:

[0006] In a first aspect, the present invention provides a base device, including a base and a translation component. The base has a mounting cavity and an arc surface located on the front side of the mounting cavity. The arc surface extends to the opening of the mounting cavity. The translation component is rotatably disposed in the mounting cavity for mounting a chair seat, so as to drive the chair seat to rotate and translate.

[0007] In an optional embodiment, the base further has clearance openings located on both sides of the mounting cavity, the clearance openings extending laterally into the mounting cavity, and the arc surface extending to the clearance openings.

[0008] In an optional embodiment, the width of the arc surface gradually increases from the portion of the arc surface near the clearance opening to the portion directly in front of the mounting cavity.

[0009] In an optional embodiment, the width of the arc surface is 30-80 mm.

[0010] In an optional embodiment, a positioning ring is provided inside the mounting cavity, and two limiting structures are provided on the inner wall of the positioning ring. The two limiting structures are opposite each other in the lateral direction of the base. The limiting structure includes at least two limiting recesses distributed circumferentially along the positioning ring. A limiting block is provided at the bottom of the translation component, and the limiting block is used to engage with one of the limiting recesses.

[0011] In an optional embodiment, the limiting structure is a groove formed by the radial outward recess of the positioning ring, and the limiting recess is formed between the bottom of the groove and the sidewall.

[0012] In an optional embodiment, the positioning ring has a rotatable connecting platform inside, and the translation component is connected to the connecting platform.

[0013] In an optional embodiment, the translation component includes a movable base and a movable platform slidably disposed on the movable base. The movable base is rotatably disposed within the mounting cavity, and the movable platform is used for mounting the chair seat.

[0014] In an optional embodiment, the translation component further includes a drive component disposed on the movable base, the drive component being connected to the movable platform and used to drive the movable platform to slide relative to the movable base.

[0015] Secondly, the present invention provides a child safety seat, including a seat and a base device as described in any of the foregoing embodiments, wherein the seat is mounted on the translation assembly.

[0016] Compared with the prior art, the beneficial effects of the embodiments of this application include, for example:

[0017] This application discloses a base device and a child safety seat. By setting an arc surface on the base, and the arc surface is located on the front side of the mounting cavity for rotatably setting the translation component, there is enough space between the arc area at the bottom of the seat and the arc surface when adjusting the angle of the seat, so that the back of the hand is less likely to touch the base, thereby reducing the risk of abrasion.

[0018] In addition, since the translation component can move the seat, the seat can be moved at multiple angles when the translation component is rotated to different angles relative to the base. This improves the problem of limited translation distance caused by different door opening angles in different car models, ensures translation distance, and makes it easier for children to get in and out of the seat.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The following detailed description of some embodiments of this application is provided with reference to Figures 1 to 7. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] This application discloses a child safety seat, which includes a seat 30 and a base device, with the seat 30 mounted on the base device.

[0036] The base device includes a base 10 and a translation component 20. The base 10 has a mounting cavity 11 and an arc surface 12 located on the front side of the mounting cavity 11. The arc surface 12 extends to the opening of the mounting cavity 11. The translation component 20 is rotatably disposed in the mounting cavity 11 for mounting the chair seat 30, so as to drive the chair seat 30 to rotate and translate.

[0037] In this way, by setting an arc surface 12 on the base 10, and the arc surface 12 being located on the front side of the mounting cavity 11 for rotatably mounting the translation component 20, sufficient space is left between the arc-shaped area at the bottom of the seat 30 and the arc surface 12 when adjusting the angle of the seat 30, making it less likely for the back of the hand to touch the base 10, thereby reducing the risk of abrasion. In addition, since the translation component 20 can drive the seat 30 to translate, the seat 30 can be translated at multiple angles when the translation component 20 is rotated relative to the base 10 to different angles. This improves the problem of limited translation distance caused by different door opening angles in different car models, ensuring translation distance and making it convenient for children to get in and out of the seat.

[0038] It should be noted that in this application, the front-to-back direction refers to the seat depth direction after the child safety seat is installed in the car, and the lateral direction refers to the seat width direction.

[0039] The translation component 20 includes a movable base 21 and a movable platform 22 slidably disposed on the movable base 21. The movable base 21 is rotatably disposed in the mounting cavity 11, and the movable platform 22 is used for mounting the chair seat 30. Thus, the translation of the chair seat 30 relative to the base 10 is achieved by sliding the movable platform 22 relative to the movable base 21.

[0040] To facilitate the lateral movement of the seat 30 by the translation component 20, the base 10 also has clearance openings 13 on both sides of the mounting cavity 11. The clearance openings 13 extend laterally into the mounting cavity 11, and the arc surface 12 extends to the clearance openings 13. After the translation component 20 rotates to the point where the moving direction of the moving platform 22 corresponds to the clearance opening 13, the moving platform 22 can easily extend out from the clearance opening 13, thereby realizing the lateral movement of the seat 30.

[0041] From the portion of the curved surface 12 near the clearance opening 13 to the portion directly in front of the mounting cavity 11, the width of the curved surface 12 gradually increases, thus better adapting to the shape of the bottom front side of the seat 30. The width of the curved surface 12 is 30-80mm.

[0042] A positioning ring 14 is provided inside the mounting cavity 11. Two limiting structures are provided on the inner wall of the positioning ring 14. The two limiting structures are opposite each other on the side of the base 10. The limiting structure includes at least two limiting recesses 15 distributed circumferentially along the positioning ring 14. A limiting block 24 is provided at the bottom of the translation component 20. The limiting block 24 is used to engage with one of the limiting recesses 15 to limit the translation component 20 when it rotates to a certain angle, so that the seat 30 is kept at a fixed angle.

[0043] For example, the limiting structure is a groove formed by the radial outward recess of the positioning ring 14, and the bottom of the groove and the sidewall of the groove form a limiting recess 15.

[0044] The positioning ring 14 has a rotatable connecting platform 17 inside. The movable base 21 of the translation component 20 is connected to the connecting platform 17, so that the connecting platform 17 drives the translation component 20 to rotate relative to the base 10.

[0045] The inner wall of the positioning ring 14 is provided with a positioning recess 16, which corresponds to the front side of the base 10, so as to keep the seat 30 facing forward when the limiting block 24 is engaged with the positioning recess 16.

[0046] To make translation easier, a drive component 23 can be used to drive the mobile platform 22 to translate. That is, the translation component 20 also includes a drive component 23 disposed on the mobile base 21. The drive component 23 is connected to the mobile platform 22 and is used to drive the mobile platform 22 to slide relative to the mobile base 21.

[0047] Specifically, the drive assembly 23 includes a telescopic motor and a transmission component. The telescopic motor is fixed to the movable base 21 and is connected to the movable platform 22 via the transmission component. The type of transmission component is not specifically limited; any component capable of transmitting power from the telescopic motor to the movable platform 22 is acceptable.

[0048] Of course, in some embodiments, the drive component 23 may also be a linear motor, with its stator fixed to the moving base 21 and its mover connected to the moving platform 22, thereby realizing the translation of the moving platform 22 relative to the moving base 21.

[0049] In summary, this application discloses a base device and a child safety seat. By providing an arc surface 12 on the base 10, and the arc surface 12 being located on the front side of the mounting cavity 11 for rotatably mounting the translation component 20, sufficient space is left between the arc-shaped area at the bottom of the seat 30 and the arc surface 12 when adjusting the angle of the seat 30, making it less likely for the back of the hand to touch the base 10, thereby reducing the risk of abrasions. In addition, since the translation component 20 can drive the seat 30 to translate, the seat 30 can be translated at multiple angles when the translation component 20 is rotated relative to the base 10 to different angles. This improves the problem of limited translation distance caused by different door opening angles in different car models, ensuring translation distance and making it convenient for children to get in and out of the seat.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
