Technical Field

[0001] The present application relates to the technical field of mother and baby products, and particularly to a base device and a child safety seat. Background Art

[0002] A child safety seat is a seat designed for children of different weights (or age groups), installed in a vehicle, and capable of effectively improving the safety of children when riding. For example, in the event of an emergency braking or a frontal collision of a vehicle, the child safety seat can reduce the impact force on the child and effectively prevent the child's body from moving forward rapidly, avoiding a secondary collision.

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

[0004] The purpose of the present application is to provide a base device and a child safety seat, where the back of the hand is not easily touched to the base, thereby reducing the risk of abrasions.

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

[0006] In a first aspect, the present utility model provides a base device, including a base and a translation component. The base has an installation cavity and an arc surface located on the front side of the installation cavity. The arc surface extends to the opening of the installation cavity. The translation component is rotatably arranged in the installation cavity for installing a seat, so as to be able to drive the seat to rotate and translate.

[0007] In an optional embodiment, the base further has avoidance openings located on both sides of the installation cavity. The avoidance openings penetrate laterally to the installation cavity, and the arc surface extends to the avoidance openings.

[0008] In an optional embodiment, from the part of the arc surface close to the avoidance opening to the part directly in front of the installation cavity, the width of the arc surface gradually increases.

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

[0010] In an optional embodiment, a positioning ring is arranged in the installation cavity. Two limiting structures are arranged on the inner wall of the positioning ring. The two limiting structures are opposite to each other in the lateral direction of the base. The limiting structure includes at least two limiting depressions distributed at intervals along the circumferential direction of the positioning ring. A limiting block is arranged at the bottom of the translation component, and the limiting block is used to fit with one of the limiting depressions.

[0011] In an alternative embodiment, the limiting structure is a groove formed by the radial outward depression of the positioning ring, and the limiting depression is formed between the bottom and the side wall of the groove.

[0012] In an alternative embodiment, a rotatable connection platform is provided inside the positioning ring, and the translation assembly is connected to the connection platform.

[0013] In an alternative embodiment, the translation assembly includes a moving base and a moving platform slidably disposed on the moving base. The moving base is rotatably disposed in the installation cavity, and the moving platform is used for installing the seat.

[0014] In an alternative embodiment, the translation assembly further includes a driving assembly disposed on the moving base. The driving assembly is connected to the moving platform and is used to drive the moving platform to slide relative to the moving base.

[0015] In a second aspect, the present utility model provides a child safety seat, which includes a seat and the base device according to any one of the foregoing embodiments. The seat is installed on the translation assembly.

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

[0017] The embodiments of the present application disclose a base device and a child safety seat. By providing an arc surface on the base, and the arc surface is located in front of the installation cavity for rotatably disposing the translation assembly. In this way, when adjusting the angle of the seat, there is enough space between the arc-shaped area at the bottom of the seat and the arc surface, and the back of the hand is not easily touched by the base, thereby reducing the risk of abrasion.

[0018] In addition, since the translation assembly can drive the seat to translate, multi-angle translation of the seat can be achieved when the translation assembly rotates to different angles relative to the base, improving the problem of limited translation distance caused by different door opening angles of different vehicle models, ensuring the translation distance, and facilitating children to get on and off the seat.

[0034] The following will Figures 1 to 7 , make a detailed description of some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] The embodiment of the present application discloses a child safety seat, which includes a seat 30 and a base device, and the seat 30 is installed on the base device.

[0036] The base device includes a base 10 and a translation assembly 20. The base 10 has an installation cavity 11 and an arc surface 12 located on the front side of the installation cavity 11. The arc surface 12 extends to the opening of the installation cavity 11. The translation assembly 20 is rotatably arranged in the installation cavity 11 for installing the seat 30 so as to be able to drive the seat 30 to rotate and translate.

[0037] In this way, by providing the arc surface 12 on the base 10, and the arc surface 12 is located on the front side of the installation cavity 11 for rotatably arranging the translation component 20, when adjusting the angle of the seat 30, there is enough space between the arc-shaped area at the bottom of the seat 30 and the arc surface 12, and the back of the hand is not easily touched to the base 10, thus reducing the risk of abrasion. In addition, since the translation component 20 can drive the seat 30 to translate, when the translation component 20 rotates to different angles relative to the base 10, multi-angle translation of the seat 30 can be achieved, improving the problem that the translation distance is limited due to different door opening angles of different vehicle models, ensuring the translation distance, and facilitating children to get on and off the seat.

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

[0039] The translation component 20 includes a moving base 21 and a moving platform 22 slidably arranged on the moving base 21. The moving base 21 is rotatably arranged in the installation cavity 11, and the moving platform 22 is used for installing the seat 30. In this way, the translation of the seat 30 relative to the base 10 is realized by the sliding of the moving platform 22 relative to the moving base 21.

[0040] In order to facilitate the translation component 20 to drive the seat 30 to translate laterally, the base 10 also has avoidance openings 13 located on both sides of the installation cavity 11. The avoidance openings 13 penetrate laterally to the installation cavity 11, and the arc surface 12 extends to the avoidance openings 13. After the translation component 20 rotates until the moving direction of the moving platform 22 corresponds to the avoidance openings 13, the moving platform 22 can conveniently extend out from the avoidance openings 13, thereby realizing the lateral translation of the seat 30.

[0041] From the part of the arc surface 12 close to the avoidance opening 13 to the front of the installation cavity 11, the width of the arc surface 12 gradually increases, so as to better adapt to the shape of the front side of the bottom of the seat 30. The width of the arc surface 12 is 30 - 80 mm.

[0042] A positioning ring 14 is arranged in the installation cavity 11. Two limiting structures are arranged on the inner wall of the positioning ring 14. The two limiting structures are opposite to each other in the lateral direction of the base 10. The limiting structure includes at least two limiting depressions 15 distributed at intervals along the circumferential direction of the positioning ring 14. A limiting block 24 is arranged at the bottom of the translation component 20. The limiting block 24 is used to fit with one of the limiting depressions 15 to realize the limit when the translation component 20 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 depression of the positioning ring 14, and the bottom and side walls of the groove form the limiting depression 15.

[0044] Inside the positioning ring 14, there is a rotatable connection platform 17. The moving base 21 of the translation assembly 20 is connected to the connection platform 17, so that the connection platform 17 drives the translation assembly 20 to rotate relative to the base 10.

[0045] On the inner wall of the positioning ring 14, there is a positioning recess 16, and the positioning recess 16 corresponds to the front side of the base 10 to keep the seat 30 facing forward when the limiting block 24 is fitted with the positioning recess 16.

[0046] In order to make the translation more labor-saving, a driving assembly 23 can be used to drive the moving platform 22 to translate. That is to say, the translation assembly 20 further includes a driving assembly 23 provided on the moving base 21. The driving assembly 23 is connected to the moving platform 22 and is used to drive the moving platform 22 to slide relative to the moving base 21.

[0047] Specifically, the driving assembly 23 includes a telescopic motor and a transmission member. The telescopic motor is fixed to the moving base 21, and the telescopic motor is connected to the moving platform 22 through the transmission member. Among them, the type of the transmission member is not specifically limited as long as it can transmit the power of the telescopic motor to the moving platform 22.

[0048] Of course, in some embodiments, the driving assembly 23 can also be a linear motor, whose stator is fixed to the moving base 21 and the rotor is connected to the moving platform 22, so as to realize the translation of the moving platform 22 relative to the moving base 21.

[0049] In summary, the embodiments of the present application disclose a base device and a child safety seat. By providing an arc surface 12 on the base 10, and the arc surface 12 is located in front of the installation cavity 11 for rotatably arranging the translation assembly 20, when adjusting the angle of the seat 30, there is enough space between the arc-shaped area at the bottom of the seat 30 and the arc surface 12, and the back of the hand is not easy to touch the base 10, thus reducing the risk of abrasion. In addition, since the translation assembly 20 can drive the seat 30 to translate, multi-angle translation of the seat 30 can be realized when the translation assembly 20 rotates to different angles relative to the base 10, improving the problem that the translation distance is limited due to different door opening angles of different vehicle models, ensuring the translation distance, and facilitating children to get on and off the seat.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
