Description

[Technical Field]

[0002] This utility model relates to the field of child safety seats, and in particular to a novel anti-misuse mechanism and an anti-misuse rotating child seat. [Background Technology]

[0004] Children's self-protection abilities are not fully developed, and they often face higher risks in traffic accidents than adults. Therefore, car safety seats specifically designed for infants and toddlers have been introduced to the market. These seats not only install easily in standard car seats but also effectively protect children's safety and comfort by providing enhanced safety and a comfortable riding experience, thus improving travel safety. To ensure children's safety while traveling, it is recommended that children under 18 months use a seat installed facing away from the direction of travel; children over 18 months can choose between forward-facing or rear-facing installation depending on their specific needs. To prevent misuse, child safety seats are equipped with an anti-misuse mechanism between the child safety seat and the vehicle mounting seat, ensuring correct installation and improving safety. However, existing anti-misuse mechanisms consist of many parts, leading to longer assembly times and increased production costs. [Utility Model Content]

[0006] To overcome the problem of increased production costs due to the large number of components and long assembly time in the anti-misuse mechanism, this utility model aims to provide a novel anti-misuse mechanism and an anti-misuse rotating child seat. This utility model is achieved through the following technical solution:

[0007] A novel anti-misuse mechanism includes a limiting mechanism for limiting the rotation angle of a base turntable. The limiting mechanism is connected to a toggle mechanism that allows a user to toggle the limiting mechanism to limit the rotation angle of the base turntable. The toggle mechanism is provided with a sliding locking part that allows the limiting mechanism to slide and lock in a state that limits and releases the rotation angle of the base turntable.

[0008] As described above, a novel anti-misuse mechanism includes a locking part for engaging with a base turntable to limit the rotation of the base turntable. The locking part is connected to a guide part for guiding the movement of the limiting mechanism. A locking member is provided on one side of the guide part for locking with a sliding locking part.

[0009] As described above, a novel anti-misuse mechanism includes a sliding locking part comprising a first inclined groove for limiting the rotation angle of the base turntable after engaging with a locking member, and a second inclined groove on one side of the first inclined groove for releasing the limiting mechanism from restricting the rotation of the base turntable after the locking member slides into the first inclined groove.

[0010] As described above, in a novel anti-misuse mechanism, the first inclined groove includes a first inclined surface for connecting with a second inclined groove so that a locking member can slide from the first inclined groove into the second inclined groove, and the first inclined surface is connected to a second inclined surface for jointly locking the locking member with the first inclined surface.

[0011] In the novel anti-misuse mechanism described above, the second inclined groove includes a third inclined surface for connecting with the first inclined surface so that the locking member can slide from the second inclined groove into the first inclined groove, and the third inclined surface is connected to a fourth inclined surface for jointly locking the locking member.

[0012] A novel anti-misuse rotating child seat includes a seat base, on which a rotatable base turntable is provided. The base turntable is provided with a limiting groove, and the novel anti-misuse mechanism described above is provided at the center of the opening of the limiting groove.

[0013] As described above, in a novel anti-misuse rotating child seat, the actuation mechanism is connected to the seat base with a second elastic element that securely limits the rotation angle of the base turntable.

[0014] As described above, a novel anti-misuse rotating child seat has a hinged joint between the limiting mechanism and the actuating mechanism, allowing the limiting mechanism and the actuating mechanism to be hinged to each other.

[0015] As described above, a novel anti-misuse rotating child seat has a limiting guide groove on the seat base that allows the limiting mechanism to maintain linear motion.

[0016] As described above, a novel anti-misuse rotating child seat has a base turntable connected to a seat body that rotates with the base turntable.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The new anti-misuse mechanism adopts a sliding locking limit mechanism and an arc-shaped reciprocating motion, which makes the structure of the new anti-misuse mechanism more concentrated and compact. As a result, the limiting mechanism and the limiting mechanism can be easily manufactured as a single piece, reducing the number of parts used in the new anti-misuse mechanism, reducing manufacturing costs, and making assembly convenient.

[0019] 2. The new anti-misuse rotating child seat can rotate within a limited rotation angle, preventing users from incorrectly facing the child seat, thereby protecting children's safety and meeting the needs of infants and toddlers for using child seats. [Attached Image Description]

Detailed Implementation Methods

[0037] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0038] Example 1: Please refer to Figure 1-11 A novel anti-misuse mechanism includes a limiting mechanism 1 for limiting the rotation angle of a base turntable. The limiting mechanism 1 is connected to a toggle mechanism 2 for the user to toggle, thereby limiting the rotation angle of the base turntable. The toggle mechanism 2 is provided with a sliding locking part 23 for the limiting mechanism 1 to slide, thereby locking the limiting mechanism 1 in a state of limiting and releasing the rotation angle of the base turntable. The toggle mechanism 2 and the limiting mechanism 1 are integrally formed. The novel anti-misuse mechanism adopts a sliding locking limiting mechanism of the toggle mechanism and uses an arc-shaped reciprocating motion, making the structure of the novel anti-misuse mechanism more concentrated and compact. As a result, the limiting mechanism and the toggle mechanism can be easily manufactured as a single piece, reducing the number of parts used in the novel anti-misuse mechanism, reducing manufacturing costs, and making assembly convenient. The assembly process is also simplified due to the reduction of parts, further saving time and costs.

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the limiting mechanism 1 includes a locking part 12 for engaging with the base turntable and thereby limiting the rotation of the base turntable. The locking part 12 is connected to a guide part 11 for guiding the limiting mechanism 1 to move. A locking member 13 is provided on one side of the guide part 11 for locking with the sliding locking part 23.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the actuating mechanism 2 includes an actuating mechanism body 21. The actuating mechanism body 21 is provided with a paddle 22 for the user to provide pushing force to rotate the actuating mechanism 2. One side of the paddle 22 is provided with a actuating hinge part 23 for hinged with the limiting mechanism 1. The actuating mechanism body 21 is an arc-shaped groove. The arc-shaped groove design provides a natural movement path for the paddle 22 and makes the user feel more comfortable when operating. The user controls the rotation of the actuating mechanism 2 by simple pushing and pulling actions, thereby limiting or removing the restriction on the rotation angle of the base turntable. Due to the reduction in the number of parts, the potential failure points are also reduced, improving the reliability and durability of the entire mechanism.

[0041] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding locking part 23 includes a first inclined groove 231 for limiting the rotation angle of the base turntable after engaging with the locking member 13 and the limiting mechanism 1. A second inclined groove 232 is provided on one side of the first inclined groove 231 for releasing the limiting mechanism 1 from restricting the rotation of the base turntable after the locking member 13 slides into the first inclined groove 231. The first inclined groove 231 is deeper than the second inclined groove 232 and closer to the rotation center of the actuating mechanism 2, so that when the locking member 13 engages with the first inclined groove 231, it extends into the limiting groove provided on the base turntable. The second inclined groove 232 is farther from the rotation center of the actuating mechanism 2 and deeper. The smaller angle than the first inclined groove 231 allows the locking member 13 to release the rotation restriction on the base turntable. The first inclined groove 231 and the second inclined groove 232 are set on the arc-shaped groove. The user can simply move the toggle mechanism 2 to switch the locking member 13 between the first inclined groove 231 and the second inclined groove 232. The operation is intuitive and convenient. Due to the different depth design of the first inclined groove 231 and the second inclined groove 232, the user can feel a significant change in resistance during operation, providing good operation feedback and enhancing the user experience. The inclined groove design usually has high strength and durability, can withstand repeated operation without being easily damaged, and is suitable for long-term frequent use.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the first inclined groove 231 includes a first inclined surface 2311 for connecting with the second inclined groove 232 so that the locking member 13 can slide from the first inclined groove 231 into the second inclined groove 232. The first inclined surface 2311 is connected to a second inclined surface 2312 for jointly locking the locking member 13. The second inclined groove 232 includes a third inclined surface 2321 for connecting with the first inclined surface 2311 so that the locking member 13 can slide from the second inclined groove 232 into the first inclined groove 231. The third inclined surface 2321 is connected to a fourth inclined surface 2322 for jointly locking the locking member 13. The connection between the first inclined surface 2311 and the third inclined surface 2321 allows the locking member 13 to switch between the first inclined groove 231 and the second inclined groove 232. The first inclined surface 2311 and the third inclined surface 2321, forming a certain angle, restrict the free movement of the locking member 13 and prevent the restricting mechanism from easily sliding.

[0043] Example 2: A novel anti-misuse rotating child seat includes a seat base 100, on which a rotatable base turntable 101 is provided. The base turntable 101 is provided with a limiting groove 1011, the angle of which is 180 degrees. A novel anti-misuse mechanism 10 as described in the above example is provided at the center of the opening of the limiting groove 1011. A hinge part 3 is provided between the limiting mechanism 1 and the actuating mechanism 2 so that the limiting mechanism 1 and the actuating mechanism 2 are hinged to each other. The seat base 100 is provided with a limiting guide groove 106 to keep the limiting mechanism 1 moving linearly. The base turntable 101 is connected to a seat body 8 that rotates with the base turntable 101.

[0044] Furthermore, as a preferred embodiment of this solution and not a limitation, the hinge portion 3 is provided with a fixing post 31 for fixing to the seat base, the guide portion 11 is provided with a guide hole 111 and an elastic element 5, the guide hole 111 is provided with a mounting post 1111, the mounting post 1111 is used to install the elastic element 5, the elastic element 5 is a spring, the fixing post 31 is disposed in the guide hole 111 so that the limiting mechanism 1 can make linear reciprocating motion relative to the fixing post 31 through the elastic element 5, the hinge portion 3 connects the limiting mechanism 1 and the actuating mechanism 2, and is fixed to the seat base by the fixing post 31, the fixing post 31 is inserted into the guide hole 111, allowing the limiting mechanism 1 to make linear reciprocating motion relative to the fixing post 31.

[0045] Furthermore, as a preferred embodiment of this solution and not a limitation, the locking part 12 is a latch. By locking or releasing the base turntable, the rotation angle of the base turntable can be restricted or released. The user only needs to simply turn the toggle mechanism 2 to complete the locking or releasing action of the locking part 12. The operation is intuitive and easy to master.

[0046] Furthermore, as a preferred embodiment of this solution and not a limitation, the actuating mechanism 2 is connected to the seat base 100 by a second elastic element 9, which makes the limiting mechanism 1 stably restrict the rotation angle of the base turntable 101. The second elastic element 9 is a spring.

[0047] Furthermore, as a preferred embodiment of this solution and not a limitation, when the locking part 12 in the novel anti-misuse mechanism 10 extends into the limiting groove 1011, after the base turntable 101 rotates 90 degrees, the side of the limiting groove 1011 will abut against the locking part 12, thereby restricting the rotation of the base turntable 101 and preventing the base turntable 101 from rotating 180 degrees, so that children under 18 months can sit facing away from the direction of vehicle travel, reducing the risk of injury to children in the event of a vehicle collision.

[0048] The working principle of this embodiment is as follows:

[0049] A novel rotating anti-misuse mechanism and anti-misuse rotating child seat are disclosed. When a child is under 18 months old, the user positions the child seat facing the car backrest. The user first moves a lever, causing the main body of the lever to rotate around the hinge point. The locking member on the limiting mechanism slides from the second inclined groove into the first inclined groove, and the engaging part moves forward and extends into the limiting groove. Due to the presence of the guide hole and elastic element in the limiting mechanism, one end of the elastic element is connected to the limiting mechanism, and the other end is connected to the fixed column, allowing the limiting mechanism to move within the travel distance of the guide hole. The elastic element provides thrust, causing the engaging part to abut against the limiting groove, ensuring that the limiting mechanism always contacts the bottom of the limiting groove. The limiting groove angle is 180 degrees. Since the starting point of the engaging part is at the middle position of the limiting groove, when the base turntable rotates, the base turntable can only rotate within a range of 0 to 90 degrees to the left and right of facing the car backrest. This achieves the angle between the child seat facing the car backrest and the child seat facing the car door, preventing the user from misusing the child seat facing the direction of car travel when the child is under 18 months old.

[0050] When the child is older than 18 months, the locking member on the limiting mechanism slides from the first inclined groove into the second inclined groove, the engaging part moves backward, and the engaging part no longer contacts the limiting groove. As a result, the limiting mechanism no longer restricts the rotation of the base turntable, and the paddle can make an arc-shaped reciprocating motion, allowing the user to select whether the child seat needs to face the car backrest or the direction of the car's travel when the child is younger than 18 months or older.

[0051] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
