Description

Technical Field

[0001] The present disclosure relates to the technical field of safety seats, and more particularly to a base for a rotating seat. Background Art

[0002] A child safety seat is a seat designed for children of different ages (or weights), installed in a vehicle, and can effectively improve the safety of children when riding. It can be fixed to a motor vehicle and is a child safety protection system composed of a seat belt assembly or a flexible component, an adjustment mechanism, accessories, etc. It can be combined with additional devices such as a portable cot, an infant carrier, an auxiliary seat, or a crash protector. It can reduce the impact force on children and limit the movement of children's bodies to reduce their injuries in the event of a vehicle collision or sudden deceleration, ensuring the safety of children when riding, and is widely used.

[0003] The patent with the patent number 201910893336.8 discloses a child safety seat and a rotating connection structure between the base and the seat body, including a base and a seat body. The seat body is pivotally connected to the base through a longitudinal fixed shaft so that the seat body can rotate relative to the base. A circular bracket fixed to the seat body is provided below the seat body to improve the stability of rotation; at least a pair of positioning holes are distributed in the circular bracket, and a linkage lock is provided on the base. A pair of locking rods collinear with the fixed shaft are provided on the linkage lock, and the locking rods respectively penetrate into a pair of positioning holes on the circular bracket to fix the positions of the base and the seat body, and multiple-point locking is used to strengthen the firmness of locking. In the above patent, after the seat body rotates to the in-place position relative to the base, the locking rods cooperate with the positioning holes to fix the base and the seat body. However, in actual use, after the seat body and the base rotate to the in-place position, due to faults or other reasons, the locking rods do not snap into the positioning holes, and the user mistakenly believes that the base and the seat body have been fixed, which has a relatively large safety hazard; or, after the seat body rotates relative to the base, it does not rotate to the in-place position (that is, the locking rods are still a short distance away from the positioning holes), but the user mistakenly believes that the seat body has rotated to the in-place position relative to the base and the base and the seat body have been fixed, which also has a huge safety hazard. Summary of the Utility Model

[0004] In view of the deficiencies and existing problems of the prior art, the present disclosure provides a base for a rotating seat, which can indicate whether the base and the seat body are fixed properly, and is safer to use.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the following will, with reference to the accompanying drawings and embodiments, describe the present disclosure in detail, clearly and completely. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0035] Those skilled in the art should understand that in the disclosure of the present utility model, the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings. These are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.

[0036] Please refer to, for example Figures 1 - 2As shown in the figure, a base for a rotating seat includes a base 1, a rotating part is provided on the base 1, a rotating mechanism is rotatably connected to the rotating part, a locking mechanism and two indicating mechanisms are provided between the base 1 and the rotating mechanism. The locking mechanism is used to limit the rotating mechanism when the rotating mechanism rotates to a specific position, and the indicating mechanism is used to indicate whether the locking mechanism limits the rotating mechanism. Generally, when a child safety seat is in normal use, either the backrest is in the front of the seat or the backrest is in the rear of the seat. A locking mechanism is provided on the side of the seat. When the backrest is in the front or rear of the seat, the locking mechanism limits the seat. After the seat is limited, it will not rotate again within a certain force range. Due to the provision of the indicating mechanism, the user can judge whether the rotating mechanism has rotated in place (the backrest rotates to the front or rear of the seat and is limited) through the indicating mechanism, so as to know whether the base and the seat body are fixed well, effectively preventing misjudgment and being safer in use.

[0037] Please refer to together as Figures 3 - 4 As shown in the figure, further, the rotating mechanism includes a cover plate 2 and a bracket 8. The bracket 8 is provided on the rotating part and can rotate on the rotating part. An installation cavity is provided on the cover plate 2. After the cover plate 2 covers the base 1, at least part of the bracket 8 is located in the installation cavity, and the cover plate 2 is installed above the bracket 8 and rotates with the rotation of the bracket 8. The rotating part is an annular guide rail 5, and the guide rail 5 is installed on the base 1 by bolts. The bracket 8 is provided with an installation opening, and part of the guide rail 5 is embedded in the installation opening and rotates along the guide rail 5.

[0038] Please refer to together Figure 7 As shown in the figure, it should be noted that the indicating mechanism includes a connecting piece 3. The connecting piece 3 is connected to the base 1. A first indicating piece 19 and a second indicating piece 20 are provided on the connecting piece 3. The first indicating piece 19 is used to indicate that the locking mechanism has limited the rotating mechanism, and the second indicating piece 20 is used to indicate that the locking mechanism has not limited the rotating mechanism. Specifically, an installation groove 11 is provided on the connecting piece 3, and the first indicating piece 19 and the second indicating piece 20 are provided in the installation groove 11; a through hole 7 is provided on the base 1, and the position of the through hole 7 corresponds to the position of the installation groove 11. The through hole 7 is used to expose the first indicating piece 19 or the second indicating piece 20 from the through hole 7 for the user to view. The first indicating piece 19 is arranged below the second indicating piece 20. The first indicating piece 19 and the second indicating piece 20 are two convex blocks with labels. The labels can be distinguished by different characters or patterns or colors, etc. Different characters or patterns or colors, etc. respectively represent that the locking mechanism has limited the rotating mechanism or the locking mechanism has not limited the rotating mechanism. Preferably, the two convex blocks are plastic parts of two different colors, such as: a red plastic convex block and a green plastic convex block. Green represents that the locking mechanism has limited the rotating mechanism, and red represents that the locking mechanism has not limited the rotating mechanism. The present disclosure is described with a red plastic convex block and a green plastic convex block.

[0039] Please refer to Figures 5 - 7 As shown, in an embodiment of the present disclosure, the cover plate 2 is provided with a disc-shaped structure. A first card slot 9 and a second card slot are provided on the disc-shaped structure. The projection of the connection line of the center points of the first card slot 9 and the second card slot on the cover plate 2 coincides with the diameter of the disc-shaped structure. A convex structure 4 is provided on the connecting member 3, and the two convex structures 4 are located below the cover plate 2. Two indicating mechanisms are provided on the base 1, and the two indicating mechanisms are respectively provided on both sides of the cover plate 2. After the cover plate 2 rotates to a specific position, the two convex structures 4 are respectively located in the first card slot 9 and the second card slot. The projection of the connection line of the center points of the two convex structures 4 on the cover plate 2 coincides with the diameter of the disc-shaped structure (the two convex structures 4 are respectively located on the left and right sides of the cover plate 2), so that the cover plate 2 is limited when the backrest rotates to the front or rear of the seat. It should be noted that the specific position here refers to the backrest rotating to the front or rear of the seat. The locking mechanism includes the first card slot 9, the second card slot and the convex structure 4. After the convex structure 4 is located in the first card slot 9 and the second card slot, the cover plate 2 is limited to a specific position. During the rotation of the cover plate 2, when the backrest rotates to the front or rear of the seat, the first card slot 9 and the second card slot respectively cooperate with the convex structure 4 to limit the cover plate 2. It should be noted that the locking mechanism does not lock the cover plate 2, but the two convex structures 4 respectively cooperate with the first card slot 9 and the second card slot to limit the cover plate 2. Since the two convex structures 4 are respectively located in the first card slot 9 and the second card slot, when rotating with a certain range of force, the cover plate 2 will not be rotated; only by rotating with a greater force can the cover plate 2 continue to rotate.

[0040] In particular, both the first card slot 9 and the second card slot are arc-shaped slots. The setting of the arc-shaped slots is to facilitate the convex structure 4 to slide out of the first card slot 9 and the second card slot when the limit is released; in addition, the setting of the arc-shaped slots also plays a buffering role, avoiding a large height difference when the convex structure 4 enters the first card slot 9 and the second card slot, resulting in a large shock feeling of the seat and avoiding bringing a bad experience to the user. Moreover, the convex structure 4 will also be damaged after long-term use due to the excessive shock feeling.

[0041] In an embodiment of the present disclosure, the connecting member 3 includes a first part 12 and a second part 13. The first part 12 is a strip-shaped structure, and the convex structure 4 is arranged on the upper edge of the first part 12 and near the first end of the first part 12. The second part 13 is connected to the second end of the first part 12, and the installation groove 11 is arranged on the second part 13. When the cover plate 2 rotates until the first card slot 9 and the second card slot just cooperate with the convex structure 4 (that is, when the backrest rotates to the front or rear of the seat), the green plastic bump exposes from the through hole 7; as the cover plate 2 rotates, if the positions of the first card slot 9 and the second card slot are staggered from the two convex structures 4 (that is, when the backrest does not rotate to the front or rear of the seat), the top of the convex structure 4 abuts against the cover plate 2, and the cover plate 2 presses the connecting member 3 downward. The connecting member 3 moves slightly downward under the pressure of the cover plate 2. At this time, the red plastic bump exposes from the through hole 7. Therefore, the user can judge whether the base and the chair body are fixed properly by visually seeing whether the red plastic bump or the green plastic bump exposes from the through hole 7.

[0042] Preferably, a step surface 14 is arranged at the connection between the first part 12 and the second part 13. The arrangement of the step surface 14 makes the second part 13 protrude towards the through hole 7, facilitating the first indicating member 19 and the second indicating member 20 to expose from the through hole 7.

[0043] Furthermore, the installation groove 11 is arranged on the first side of the second part 13, and a reinforcing rib structure is arranged on the second side of the second part 13. Since the connecting member 3 is always in a stressed state, the reinforcing rib structure is for strengthening the structural strength of the connecting member 3. Since the first part 12 is subjected to greater stress, at least two hollow holes 10 are also arranged on the first part 12 for increasing the elastic performance of the connecting member 3 and preventing the connecting member 3 from breaking.

[0044] As Figures 8 - 11 shown, in an embodiment of the present disclosure, the connecting member 3 is a block structure, and the convex structure 4 is arranged in the middle of the block structure. The base 1 includes a housing 15, and the housing 15 is arranged outside the disc-shaped structure. A limiting cavity is arranged on the housing 15, and the connecting member 3 is located in the limiting cavity. Specifically, the limiting cavity is arranged inside the housing 15. The limiting cavity is composed of two relatively arranged first plates 16, a second plate 17 connected to the two first plates 16, and the side plate of the housing 15. Among them, the second plate 17 is relatively arranged with the side plate of the housing 15, and convex strips are respectively arranged on the two first side plates. The two ends of the connecting member 3 abut against the convex strips, thereby limiting the connecting member 3 in the limiting cavity. In order to prevent the connecting member 3 from deviating or shaking circumferentially during the up and down movement, two limiting protrusions 18 are arranged in the limiting cavity, and two limiting grooves 21 are arranged on the connecting member 3. The limiting protrusions 18 are located in the limiting grooves 21 for limiting the connecting member 3, so as to ensure that the convex structure 4 is just located directly below the first card slot 9 or the second card slot.

[0045] The above has introduced the present application in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only for helping to understand the present application and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
