[0037] Embodiment 1

[0038] Embodiment 1 of the present invention provides a rotating indicating base, combined with Figure 1 , Figure 2 , Figure 3 As shown, it includes a base body 1, a rotating disk 2 and an indicator 3. The rotating disk 2 is installed on the base body 1, and the rotating disk 2 rotates relative to the base body 1 and has a locked state and an unlocked state; a mounting cavity 111 is provided in the base body 1, and a rotating shaft 112 is provided in the mounting cavity 111 of the base body 1, and the indicator 3 is rotatably installed in the mounting cavity 111 through the rotating shaft 112, and a first indicator block 331 corresponding to the locked state and a second indicator block 332 corresponding to the unlocked state are provided on the indicator 3, and a window 121 for the first indicator block 331 or the second indicator block 332 to rotate and indicate is provided on the base body 1.

[0039] Therefore, the user can know that the rotating disk 2 is in a locked state by seeing the first indicator block 331 displayed in the window 121. Correspondingly, the user can know that the rotating disk 2 is in an unlocked state by seeing the second indicator block 332 displayed in the window 121, so that the user can always clearly, intuitively and safely know the rotation progress of the rotating disk 2.

[0040] The base body 1 of the present invention can be an integrated structure or can be formed by assembling a plurality of parts. In this embodiment, the base body 1 includes a base lower cover 11 and a base upper cover 12 installed above the base lower cover 11, so as to realize the detachable assembly and assembly of the base body 1. In this embodiment, the base upper cover 12 and the base lower cover 11 are fixed by snap connection, which helps to improve the disassembly and assembly efficiency of the base body 1 compared with the method of fixing by fasteners such as bolts. The installation cavity 111 is opened on the top surface of the base lower cover 11 and is covered from top to bottom by the base upper cover 12. The above-mentioned opening method makes the opening of the installation cavity 111 larger, which is convenient for the quick assembly and disassembly of the indicator 3 and other components to be installed in the installation cavity 111.

[0041] A mounting position 122 is provided in the middle of the upper cover 12 of the base. The mounting position 122 can be a perforation, a concave cavity, or other structures that can be adapted to the chassis 21 and realize relative rotation. The mounting position 122 in this embodiment is specifically shown as a perforated structure. The mounting position 122 is connected to the mounting cavity 111. The bottom of the rotating disk 2 is rotatably connected to the lower cover 11 of the base through the mounting position 122. When the rotating disk 2 rotates relative to the lower cover 11 of the base, the hole wall of the mounting position 122 can prevent the rotating disk 2 from radially swinging, thereby improving the rotation efficiency of the rotating disk 2. The indicator 3 is correspondingly rotatably installed on the front side of the lower cover 11 of the base. The lower cover 11 of the base can provide a good bottom support for the indicator 3, which helps the indicator 3 to rotate smoothly. The window 121 is correspondingly opened on the front side of the upper cover 12 of the base, so that the opening of the window 121 is upward and located on the front side, so as to facilitate the user to observe.

[0042] Optionally, the rotating disk 2 includes a chassis 21 and a seat frame 22 mounted on the chassis 21, the chassis 21 is inserted into the mounting position 122 and is rotatably connected to the base lower cover 11, and a plurality of first matching structures 211 are arranged at intervals on the circumferential surface of the chassis 21, and the first matching structures 211 correspond to the locking state one by one, and the number of the first matching structures 211 can be arranged according to the actual use function (locking gear mode) of the seat. The rotating disk 2 in this embodiment has two locking gear modes, namely, forward locking and reverse locking, wherein the forward locking corresponds to the seat orientation of the rotating disk 2 being consistent with the seat orientation of the base body 1, that is, the child sits forward; the reverse locking corresponds to the seat orientation of the rotating seat being opposite to the seat orientation of the address body, that is, the child sits backward. Based on this, two first matching structures 211 are correspondingly arranged on the chassis 21 of this embodiment, and the two first matching structures 211 are symmetrically located on opposite sides of the chassis 21. One end of the indicator 3 extends into the installation position 122 , and the first matching structure 211 abuts against the indicator 3 to drive the indicator 3 to rotate until the first indicator block 331 is displayed at the window 121 .

[0043] The structure of the indicator 3 can be adjusted as needed. In order to further improve the rotation efficiency of the indicator 3, the indicator 3 includes a rotating cylinder 31, a lever 32 and an indicator plate 33 connected in sequence. The rotating cylinder 31 is sleeved on the rotating shaft 112 and rotates relative to the rotating shaft 112, so that the indicator 3 rotates with the rotating shaft 112 as the rotation center. The rotating cylinder 31 is provided with a protrusion 311 on the cylinder wall away from the lever 32, which is rotatably abutted with the first matching structure 211. In this embodiment, the form of the first matching structure 211 can be adjusted as needed, including but not limited to the form of a convex point, a convex strip, a boss, etc. In addition, the first matching structure 211 can also be shown in the form of a groove, etc. Correspondingly, the protrusion 311 on the indicator 3 is correspondingly inserted into the groove, so as to realize that the indicator 3 rotates to point to the corresponding window. In this embodiment, the first matching structure 211 is specifically shown as a vertically arranged convex strip, and the protrusion 311 is also a vertically arranged convex strip. At this time, the protrusion 311 and the first matching structure 211 are in line contact, which has better rotation stability than point contact and can reduce friction compared to surface contact. Therefore, the indicator 3 is in the shape of a pendulum needle as a whole, so as to facilitate left and right swinging.

[0044] The first indicator block 331 and the second indicator block 332 are arranged on the indicator board 33. The first indicator block 331 and the second indicator block 332 can be distinguished by different colors. Specifically, the first indicator block 331 is marked as green, and the second indicator block 332 is marked as red. Bright colors are used to improve recognition and facilitate user observation.

[0045] Optionally, the locking state of each locking gear mode of the rotating disk 2 has a positive locking state (left rotation to the position, combined with Figure 4 and Figure 5 ) and reverse locking state (left rotation, combined with Figure 6 and Figure 7 ), and in this embodiment, it is further preferred to have both of these locking states, so as to increase the rotation direction of the rotating disk 2 when it needs to be locked, thereby improving the user experience of the user; the unlocking state of the rotating disk is a state other than the above-mentioned forward locking state and reverse locking state (combined with Figure 8 and Fig. 9). Two first indicator blocks 331 are provided and located on opposite sides of the second indicator block 332, that is, the first indicator blocks 331 showing green on the indicator member 3 are located on the left and right sides, and the second indicator block 332 showing red is located in the middle, so as to satisfy the color indication of the two locked states and the unlocked state. Therefore, whether the rotating disk 2 rotates forward or reverse, as long as the protrusion 311 abuts against the first matching structure 211, the "locked state" can be effectively indicated. If the protrusion 311 is separated from the first matching structure 211, the "unlocked state" can be effectively indicated, which not only satisfies the rotation freedom of the rotating disk 2, but also helps the user to always grasp the rotation progress of the rotating disk 2.

[0046] Optionally, combined Fig.10 and Fig.11 The rotating indicating base of this embodiment also includes a resetting elastic member 4, which can be a structure with elastic restoring force such as a spring or an elastic rope, and is specifically shown as a spring in the figure. One end of the resetting elastic member 4 is installed on the indicating member 3, and the other end of the resetting elastic member 4 is installed on the base lower cover 11. Figure 5 and Figure 7 When the first matching structure 211 abuts against the protrusion 311, the first matching structure 211 drives the indicator 3 to rotate and thus drives the resetting elastic member 4 to be stretched; Fig. 9 After the first matching structure 211 is separated from the indicator protrusion 311, the indicator 3 loses the pushing force, and the restoring force of the reset elastic member 4 pulls the indicator 3 to rotate in the opposite direction for reset. At this time, the second indicator block 332 is shown at the window 121, indicating that the rotating disk 2 is in the unlocked state.

[0047] Optionally, a clearance groove 34 is formed on the lower side of the lever 32 and the indicator plate 33, and the reset elastic member 4 is installed in the clearance groove 34, which can not only increase the tightness between the structures to improve space utilization, but also protect the reset elastic member 4 from being squeezed and damaged by the external structure.

[0048] The indicator plate 33 of this embodiment is provided with a first positioning column 333 in the clearance groove 34, the base lower cover 11 is provided with a second positioning column 113 in the installation cavity 111, and the two ends of the reset elastic member 4 are respectively sleeved on the first positioning column 333 and the second positioning column 113. When the indicator 3 is rotated to reset, the rotation shaft 112, the first positioning column 333 and the second positioning column 113 are located in the same plane, and the first positioning column 333 and the second positioning column 113 provide good support for the reset elastic member 4, thereby prompting the indicator 3 to reset effectively and quickly.

[0049] Optionally, combined Figure 3 and Figure 4 The base lower cover 11 is provided with a baffle 114 adapted to the side of the indicator plate 33 away from the rotating cylinder 31, and the baffle 114 is located at the rotating shaft 112 (combined with Fig.11 ) and are respectively provided on the front side of the second positioning column 113, and the indicator plate 33 is guided to rotate along the baffle plate 114. On the one hand, the two baffle plates 114 can limit the separation of the reset elastic member 4 from the second positioning seat, thereby increasing the installation stability of the reset elastic member 4. On the other hand, when the indicator plate 33 rotates, the stretched reset elastic member 4 can be protected to reduce the entry of foreign matter and interfere with the extension and contraction of the reset elastic member 4.

[0050] The implementation principle of this embodiment is:

[0051] The indication method of rotating disk 2 turning right to the right position (locked state) is as follows: Figure 4 and Figure 5 When the rotating disk 2 is ready to rotate into position, the first matching structure 211 on the rotating disk 2 contacts and abuts against the protrusion 311 of the indicator 3. The rotating disk 2 continues to rotate and drives the indicator 3 to rotate through the contact of the first matching structure 211; when the rotating disk 2 is rotated into position, the indicator 3 rotates a certain angle, and the first indicator block 331 (green) on the indicator 3 is shown at the window 121, and the reset elastic member 4 is in a stretched state. At this time, the user can clearly see the green indicator color through the window 121, and can then use the rotating indicator base with confidence. The indication method of the rotating disk 2 rotating to the left is combined with Figure 6 and Figure 7 , which is the same as the above-mentioned indication method of right-hand rotation, so it will not be further explained.

[0052] When the rotating disk 2 is not rotated to the use position (unlocked state), the Figure 8 and Fig. 9 At this time, the first matching structure 211 on the rotating disk 2 is disengaged from the protrusion 311 of the indicator 3, and the indicator 3 will be centered under the action of the reset elastic member 4. The second indicator block 332 (red) on the indicator 3 is shown at the window 121. At this time, the user can clearly see the red indicator color through the window 121, and then know that the rotating indicator base is in an incorrect position, prompting the user to rotate it to the correct position for use.

[0053] In summary, the rotating indicator base of the present embodiment allows the user to clearly, intuitively and confidently grasp the rotation progress of the rotating disk 2 at all times, effectively reducing the situation where the rotating disk 2 is not rotated properly or rotated excessively, thereby improving the correctness of the user when using the corresponding seat, and can also improve the rotation efficiency of the seat to a certain extent, enhance the user's confidence in the safety of the seat and the good experience, and be more competitive in the market. In addition, the indicator 3 designed in the present embodiment is an independent structure. Compared with the prior art that combines the indicator structure with the locking mechanism for locking the rotation of the rotating disk 2 and the base body 1, the indicator 3 of the present embodiment has the characteristics of simple structure, strong versatility and operability, convenient installation, and a wide range of use, and can be well applied to different types of seats.
