Detailed Implementation

[0027] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 10 As shown, this utility model provides a rotating and folding structure for a child safety seat. The structure includes a backrest 10, a base 20, and a locking member 30. The backrest 10 is movably mounted on the base 20, and the locking member 30 is slidably mounted on the backrest 20. The base 20 is provided with a locking groove 21 that is adapted to the locking member 30. When the backrest 10 and the base 20 are upright, the locking member 30 slides into the locking groove 21 to lock the backrest 10 and the base 20, keeping the backrest 10 and the base 20 in an upright state. When the locking member 30 slides out of the locking groove 21, the backrest 10 can rotate relative to the base 20, realizing the folding and folding of the backrest 10 and the base 20.

[0030] When the child safety seat is not in use after being installed in the car seat, or when it needs to be packaged, stored and transported, the locking piece 30 can be slid out of the locking groove 21, and then the backrest 10 can be rotated relative to the base 20 until the backrest 10 and the base 20 are folded together, thereby reducing the space occupied by the entire child safety seat and making it convenient for use, packaging and transportation.

[0031] Specifically, the backrest 10 has a sliding groove 11 for the locking member 30 to slide. The extension direction of the sliding groove 11 is the same as the height extension direction of the backrest 10. There can be multiple sliding grooves 11 or one sliding groove. When there are multiple sliding grooves 11, there are also multiple locking members 30, and each locking member 30 is slidably disposed in the sliding groove 11. At this time, there are also multiple locking grooves 21 on the base 20 to accommodate multiple locking members 30. In this embodiment, the sliding groove 11, the locking member 30 and the locking groove 21 are all one, and the sliding groove 11 is located on the center line in the width direction of the backrest 10, and the locking groove 21 is located on the center line in the width direction of the base 20.

[0032] The slide groove 11 is provided with a pair of through holes 12 and a protruding locking block 13. The locking member 30 is provided with a pair of limiting holes 31 and a locking groove 32. The limiting holes 31, the locking groove 32 and the slide groove 11 extend in the same direction. The limiting holes 31 correspond one-to-one with the through holes 12. A positioning pin passes through the through holes 12 and the limiting holes 31. The positioning pin is not shown in the figure. The locking block 13 is engaged in the locking groove 32. Through the arrangement of the through holes 12, the limiting holes 31, the positioning pin, the locking groove 32 and the locking block 13, the sliding of the locking member 30 in the slide groove 11 can be effectively limited. In this embodiment, the locking block 13 is located on the center line of the slide groove 11. The pair of through holes 12 are symmetrically arranged on both sides of the locking block 13. The height of the limiting holes 31 is less than the height of the locking groove 32. That is, the travel limitation of the locking member 30 is mainly achieved by limiting the limiting holes 31.

[0033] The lower end of the slide groove 11 extends downward to form a protrusion 14. The bottom of the protrusion 14 is provided with an arc-shaped protrusion 15, which extends along the width direction of the backrest 10. Correspondingly, the base 20 is provided with a second groove 22, which is formed by recessing downward from the upper end of the base 20. The second groove 22 is through the front and back, and is adjacent to the locking groove 21. The protrusion 14 extends into the second groove 22 and rotates relative to the second groove 22. The bottom of the second groove 22 is provided with an arc-shaped groove 23, which is adapted to the arc-shaped protrusion 15. When the backrest 10 and the base 20 are upright, the arc-shaped protrusion 15 is located in the arc-shaped groove 23, which slides the locking member 30 into the locking groove 21, thereby locking the backrest 10 and the base 20 upright. The protrusion 14 and the locking member 30 are adjacent to each other.

[0034] The base 20 is also provided with a pair of third grooves 24, and a support member 40 is fixed in the third groove 24. The bottom of the third groove 24 is flat so as to effectively fix the support member 40. In this embodiment, the third groove 24 is symmetrically arranged with respect to the second groove 22. The support member 40 extends upward. The bottom of the backrest 10 is provided with a pair of first grooves 16. The first grooves 16 are symmetrically arranged with respect to the slide groove 11. The support member 40 is provided with a pivot. The backrest 10 is rotatably connected to the support member 40 through the pivot, that is, the backrest 10 is rotatably connected to the base 20 through the pivot.

[0035] Specifically, a pair of through holes 17 are provided on both sides of the backrest 10 in the width direction. The through holes 17 correspond one-to-one with the first grooves 16, and the through holes 17 are connected to the first grooves 16. The support member 40 corresponds one-to-one with the first grooves 16, and the upper end of the support member 40 extends into the first groove 16. The rotating shaft passes through the through hole 17 and is mounted on the support member 40, abutting against the side of the first groove 16 away from the through hole 17. That is, the rotating shaft passes through the through hole 17 and is mounted on the support member 40, with one end of the rotating shaft located in the through hole 17 and the other end abutting against the side of the first groove 16 into which the support member 40 extends. Then, a plug is placed in the through hole 17 to prevent the rotating shaft from falling out of the through hole 17. That is, the plug restricts the rotating shaft so that it cannot move along the width direction of the backrest 10. The rotating shaft and the plug are not shown in the figure. Of course, the arrangement of the rotating shaft is not limited to the above one, as long as it can realize the rotational connection between the backrest 10 and the base 20.

[0036] The pivot is inserted through the through hole 17, the support member 40, and the side wall of the first groove 16, so that the backrest 10 can rotate relative to the base 20 via the pivot. Of course, the number of the first groove 16, the pivot, and the support member 40 can be a pair, a single one, or even more than a pair. When the number of the support member 40, the first groove 16, and the pivot is a single one, the locking member 30 can be a pair. In this case, the pivot is longer, and the locking member 30 is located on both sides of the pivot. When the number of the support member 40, the first groove 16, and the pivot is more than a pair, the locking member 30 can be located between adjacent support members 40. Regardless of the arrangement, the main goal is to achieve a more stable folding of the backrest 10 and the base 20.

[0037] When the car seat needs to be packaged, transported, or not used after installation, the locking member 30 can be slid upwards along the slide groove 11 out of the locking groove 21, and then the backrest 10 can be rotated to fold the backrest 10 and the base 20 together. This can greatly reduce the space occupied by the entire car seat, making it convenient for packaging, transport, and use. When it is needed, the backrest 10 can be rotated to an upright position with the base 20, and then the locking member 30 can be slid downwards to slide into the locking groove 21. At this time, the backrest 10 and the base 20 can be kept upright for use.

[0038] This utility model has been described through several specific embodiments. Those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or circumstances without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.
