Description

A rotating indicator base and a child safety seat Technical Field

[0001] This invention relates to the field of child safety seat technology, and more specifically, to a rotating indicator base and a child safety seat. Background Technology

[0002] A child safety seat is a seat specifically designed for children of different weights (or ages) and installed in a car to effectively improve child passenger safety. With rising consumer expectations, more and more people are prioritizing seats with a rotating function when choosing a child seat, making it easier for users to get their children in and out of the seat. Existing child safety seats with a rotating function generally consist of a base and a seat body mounted on the base. The seat body can rotate relative to the base, and both the seat body and the base are locked in place by a locking mechanism. However, during the rotation process, it is difficult for users to visually monitor the progress, which can easily lead to incomplete or excessive rotation. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a rotating indicator base and a child safety seat, which allows users to clearly, intuitively, and confidently monitor the rotation progress, thereby improving the rotation efficiency of the child safety seat.

[0004] In a first aspect, the present invention provides a rotating indicator base, comprising a base body, a rotating disk, and an indicator element. The rotating disk is mounted on the base body and rotates relative to the base body, having a locked state and an unlocked state. A rotating shaft is provided inside the base body, and the indicator element is rotatably mounted inside the base body via the rotating shaft. The indicator element has a first indicator block corresponding to the locked state and a second indicator block corresponding to the unlocked state. A window is provided on the base body for the first indicator block or the second indicator block to rotate and be displayed.

[0005] Optionally, the rotating disk includes a chassis and a seat frame mounted on the chassis. The base body has a mounting position for the chassis to be inserted and rotate relative to it. The chassis has a first mating structure, which corresponds one-to-one with the locking state. One end of the indicator extends into the mounting position. The first mating structure abuts against the indicator to drive the indicator to rotate until the first indicator block is shown at the window.

[0006] Optionally, the rotating disk has a forward locking state and a reverse locking state, and the first indicator block is provided in two places and located on opposite sides of the second indicator block.

[0007] Optionally, the rotating indicator base further includes a reset elastic element, one end of which is mounted on the indicator and the other end of which is mounted on the base body. The indicator is rotated and reset by the reset elastic element until the second indicator block is shown at the window.

[0008] Optionally, the indicator includes a rotating cylinder, a lever, and an indicator plate connected in sequence. The rotating cylinder is sleeved on the rotating shaft. The rotating cylinder has a protrusion on the cylinder wall away from the lever that rotates and abuts against the first mating structure. The first indicator block and the second indicator block are disposed on the indicator plate.

[0009] Optionally, the lever and the lower side of the indicator plate form a clearance groove, and the reset elastic element is installed in the clearance groove.

[0010] Optionally, the indicator plate is provided with a first positioning post in the clearance groove, and the base body is provided with a second positioning post. The two ends of the reset elastic member are respectively fixed on the first positioning post and the second positioning post. When the indicator member is rotated to reset, the rotation shaft, the first positioning post and the second positioning post are located in the same plane.

[0011] Optionally, the base body includes a lower base cover and an upper base cover mounted above the lower base cover. The mounting position is opened on the upper base cover, the chassis passes through the mounting position and is rotatably connected to the lower base cover, and the indicator is rotatably mounted inside the lower base cover.

[0012] Optionally, the lower cover of the base is provided with a baffle that is adapted to the side of the indicator plate away from the rotating cylinder. The baffle is provided on each of the opposite sides of the second positioning post, and the indicator plate rotates along the baffle.

[0013] In a second aspect, the present invention provides a child safety seat, including the rotating indicator base as described above.

[0014] The rotating indicator base and child safety seat of this invention have the following beneficial effects:

[0015] 1. When using the rotating indicator base of the present invention, the user can know that the rotating disk is in the locked state by seeing the first indicator block displayed in the window, and correspondingly, the user can know that the rotating disk is in the unlocked state by seeing the second indicator block displayed in the window. This allows the user to clearly, intuitively and confidently know the rotation progress, effectively reducing the situation of incomplete or excessive rotation, and thus improving the rotation efficiency of the child safety seat to a certain extent.

[0016] 2. In this invention, the first mating structure corresponds one-to-one with the locking state. The number of the first mating structures can be arranged according to the actual number of functions used by the seat. The first mating structure is then used to drive the indicator to rotate. The indicator is an independent structure. Compared with the prior art, which combines the indicator structure with the locking mechanism used to lock the rotating disc and the base body, the indicator of this invention has the characteristics of simple structure, versatility and strong operability, convenient installation and wide range of use, and can be well applied to different types of seats.

[0017] 3. The rotating disk in this invention has a forward locking state and a reverse locking state. Correspondingly, two first indicator blocks are provided on the indicator, and with the help of the reset elastic element, the indicator can be reset in time. In this way, the progress of the rotating disk in both forward and reverse rotation can be fully displayed. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] 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.

[0034] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this invention 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 of this invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. The accompanying drawings of embodiments of the present invention provide a coordinate system XYZ, where the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the rear, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other. Example 1

[0037] Embodiment 1 of the present invention provides a rotating indicator base, as shown in Figures 1, 2, and 3, comprising a base body 1, a rotating disk 2, and an indicator 3. The rotating disk 2 is mounted on the base body 1 and rotates relative to the base body 1, having a locked state and an unlocked state. The base body 1 has a mounting cavity 111, and the base body 1 has a rotating shaft 112 within the mounting cavity 111. The indicator 3 is rotatably mounted within the mounting cavity 111 via the rotating shaft 112. The indicator 3 has a first indicator block 331 corresponding to the locked state and a second indicator block 332 corresponding to the unlocked state. The base body 1 has a window 121 for rotating the first indicator block 331 or the second indicator block 332 to indicate the position.

[0038] Thus, when the user sees the first indicator block 331 displayed in the window 121, they can know that the rotating disk 2 is in a locked state. Correspondingly, when the user sees the second indicator block 332 displayed in the window 121, they can know that the rotating disk 2 is in an unlocked state. This allows the user to clearly, intuitively and confidently know the rotation progress of the rotating disk 2 at all times.

[0039] The base body 1 of this invention can be a one-piece structure or assembled from multiple parts. In this embodiment, the base body 1 includes a lower base cover 11 and an upper base cover 12 mounted on the lower base cover 11, thereby enabling the base body 1 to be detachable. In this embodiment, the upper base cover 12 and the lower base cover 11 are fixed by a snap-fit, which helps to improve the assembly and disassembly efficiency of the base body 1 compared to fixing with bolts or other fasteners. The mounting cavity 111 is opened on the top surface of the lower base cover 11 and is closed from top to bottom by the upper base cover 12. The above-mentioned opening method makes the opening of the mounting cavity 111 larger, which facilitates the quick installation and removal of the indicator 3 and other components that need to be installed in the mounting cavity 111.

[0040] A mounting position 122 is provided in the middle of the upper base cover 12. This mounting position 122 can be a through hole, a cavity, or other structures that can be adapted to the chassis 21 and achieve relative rotation. In this embodiment, the mounting position 122 is specifically shown as a through hole structure. This mounting position 122 is connected to the mounting cavity 111. The bottom of the rotating disk 2 passes through the mounting position 122 and is rotatably connected to the lower base cover 11. Thus, when the rotating disk 2 rotates relative to the lower base cover 11, the hole wall of the mounting position 122 can prevent the rotating disk 2 from swaying radially, improving the rotation efficiency of the rotating disk 2. The indicator 3 is rotatably mounted on the front side of the lower base cover 11. The lower base cover 11 provides good bottom support for the indicator 3, which helps the indicator 3 to rotate smoothly. The window 121 is opened on the front side of the upper base cover 12, so that the opening of the window 121 faces upward and is located on the front side, which facilitates the user's observation.

[0041] Optionally, the rotating disc 2 includes a chassis 21 and a seat frame 22 mounted on the chassis 21. The chassis 21 passes through the mounting position 122 and is rotatably connected to the base cover 11. Multiple first engaging structures 211 are spaced apart on the circumferential surface of the chassis 21. Each first engaging structure 211 corresponds to a locking state, and the number of first engaging structures 211 can be arranged according to the actual usage functions (locking modes) of the seat. In this embodiment, the rotating disc 2 has two locking modes: forward locking and reverse locking. Forward locking corresponds to the seat orientation of the rotating disc 2 being the same as the seat orientation of the base body 1, i.e., the child sits forward. Reverse locking corresponds to the seat orientation of the rotating disc 2 being opposite to the seat orientation of the base body 1, i.e., the child sits backward. Based on this, two first engaging structures 211 are correspondingly provided on the chassis 21 of this embodiment, and the two first engaging structures 211 are symmetrically located on opposite sides of the chassis 21. One end of the indicator 3 extends into the mounting position 122, and the first mating structure 211 abuts against the indicator 3, thereby driving the indicator 3 to rotate until the first indicator block 331 is shown in the window 121.

[0042] The structure of the indicator 3 can be adjusted as needed. In this embodiment, 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, thereby causing the indicator 3 to rotate around the rotating shaft 112 as the rotation center. The rotating cylinder 31 has a protrusion 311 on the cylinder wall away from the lever 32, which rotates and abuts against the first mating structure 211. In this embodiment, the shape of the first mating structure 211 can be adjusted as needed, including but not limited to protrusions, protrusions, bosses, etc. In addition, the first mating structure 211 can also be shown in the form of a groove, etc. Correspondingly, the protrusion 311 on the indicator 3 is inserted into the groove, thereby realizing that the indicator 3 rotates to point to the corresponding window. In this embodiment, the first mating structure 211 is specifically shown as a vertically arranged protrusion, and the protrusion 311 is also a vertically arranged protrusion. At this time, the protrusion 311 and the first mating structure 211 are in line contact, which has better rotational stability than point contact and reduces friction compared to surface contact. Thus, the indicator 3 is shaped like a pendulum needle to facilitate left and right swinging.

[0043] The first indicator block 331 and the second indicator block 332 are disposed on the indicator plate 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. The bright colors are used to improve the recognition and facilitate the user's observation.

[0044] Optionally, the rotating disk 2 has one or both of the following locking states for each locking mode: a forward locking state (leftward rotation to the left, referring to Figures 4 and 5) and a reverse locking state (leftward rotation to the left, referring to Figures 6 and 7). In this embodiment, it is further preferred to have both of these locking states, thereby increasing the rotation direction of the rotating disk 2 when locking is required and improving the user experience. The unlocking state of the rotating disk is any state other than the aforementioned forward and reverse locking states (referring to Figures 8 and 9). Two first indicator blocks 331 are provided correspondingly and located on opposite sides of the second indicator block 332. That is, the first indicator block 331 displaying green on the indicator 3 is located on the left and right sides, and the second indicator block 332 displaying red is located in the middle, thereby satisfying the color indication of the two locking states and the unlocking state. Therefore, whether the rotating disk 2 rotates in the forward or reverse direction, as long as the protrusion 311 abuts against the first mating structure 211, it can effectively indicate the "locked state". If the protrusion 311 separates from the first mating structure 211, it can effectively indicate the "unlocked state". This satisfies the rotational freedom of the rotating disk 2 and helps the user to keep track of the rotation progress of the rotating disk 2 at all times.

[0045] Optionally, referring to Figures 10 and 11, the rotating indicator base of this embodiment also includes a reset elastic element 4. The reset elastic element 4 can be a structure with elastic restoring force, such as a spring or elastic rope; specifically, a spring is shown in the figures. One end of the reset elastic element 4 is mounted on the indicator 3, and the other end is mounted on the lower cover 11 of the base. Referring to Figures 5 and 7, when the first engaging structure 211 abuts against the protrusion 311, the first engaging structure 211 pushes the indicator 3 to rotate, thereby causing the reset elastic element 4 to be stretched. Referring to Figure 9, after the first engaging structure 211 separates from the indicator protrusion 311, the indicator 3 loses its pushing force, and the restoring force of the reset elastic element 4 pulls the indicator 3 to rotate in the opposite direction to reset. At this time, the second indicator block 332 is shown in window 121, indicating that the rotating disk 2 is in the unlocked state.

[0046] Optionally, a relief groove 34 is formed on the lower side of the lever 32 and the indicator plate 33. The reset elastic member 4 is installed in the relief 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 the squeezing and damage of the external structure.

[0047] In this embodiment, the indicator plate 33 has a first positioning post 333 in the relief groove 34, and the base cover 11 has a second positioning post 113 in the mounting cavity 111. The two ends of the reset elastic member 4 are respectively sleeved on the first positioning post 333 and the second positioning post 113. When the indicator 3 rotates to reset, the rotation shaft 112, the first positioning post 333 and the second positioning post 113 are located on the same plane. The first positioning post 333 and the second positioning post 113 provide good support for the reset elastic member 4, thereby enabling the indicator 3 to reset effectively and quickly.

[0048] Optionally, referring to Figures 3 and 4, the lower cover 11 of the base is provided with a baffle 114 adapted to the side of the indicator plate 33 away from the rotating cylinder 31. The baffle 114 is located in front of the rotating shaft 112 (referring to Figure 11) and is provided on the left and right sides of the second positioning post 113 respectively. The indicator plate 33 rotates along the baffle 114. The two baffles 114 can, on the one hand, restrict the reset elastic member 4 from detaching from the second positioning seat, increase the installation stability of the reset elastic member 4, and on the other hand, protect the stretched reset elastic member 4 when the indicator plate 33 rotates, reducing the entry of foreign objects that may interfere with the extension and contraction of the reset elastic member 4.

[0049] The implementation principle of this embodiment is as follows:

[0050] The method for indicating that the rotating disk 2 is in the right-hand position (locked state) is as follows: Referring to Figures 4 and 5, when the rotating disk 2 is about to rotate into position, the first mating structure 211 on the rotating disk 2 contacts and abuts against the protrusion 311 of the indicator 3. As the rotating disk 2 continues to rotate, it will cause the indicator 3 to rotate through the contact of the first mating structure 211. When the rotating disk 2 is in position, the indicator 3 will rotate at a certain angle, and the first indicator block 331 (green) on the indicator 3 will be shown in window 121. The reset elastic element 4 is in a stretched state. At this time, the user can clearly see the green indicator color through window 121, and can use the rotating indicator base with confidence. The method for indicating that the rotating disk 2 is in the left-hand position is the same as the method for indicating that it is in the right-hand position, as shown in Figures 6 and 7, and therefore will not be described further.

[0051] When the rotating disk 2 is not rotated to the use position (unlocked state), referring to Figures 8 and 9, the first mating structure 211 on the rotating disk 2 disengages from the protrusion 311 of the indicator 3. Under the action of the reset elastic member 4, the indicator 3 will be centered in place. The second indicator block 332 (red) on the indicator 3 is shown in window 121. At this time, the user can clearly see the red indicator color through window 121, and thus know that the rotating indicator base is in an incorrect use position, prompting the user to rotate it to the correct use position.

[0052] In summary, the rotating indicator base of this embodiment allows users to clearly, intuitively, and confidently monitor the rotation progress of the rotating disk 2 at all times, effectively reducing the possibility of the rotating disk 2 not rotating completely or over-rotating. This improves the user's accuracy when using the corresponding seat and also enhances the seat's rotation efficiency to a certain extent, increasing user confidence in the seat's safety and overall experience, making it more competitive in the market. Furthermore, the indicator 3 designed in this embodiment is an independent structure. Compared to existing technologies that integrate the indicator structure with the locking mechanism used to lock the rotation of the rotating disk 2 and the base body 1, the indicator 3 in this embodiment features a simple structure, versatility, strong operability, convenient installation, and wide applicability, making it well-suited for different types of seats. Example 2

[0053] Embodiment 2 of the present invention provides a child safety seat, including the rotating indicator base described in Embodiment 1. Its beneficial effects are the same as those in Embodiment 1, and will not be further described here.

[0054] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
