[0002] With the development of social economy and the enhancement of people's safety awareness, the importance of child safety seats in the field of traffic safety has become increasingly prominent. Studies have shown that the risk of children being injured or killed in traffic accidents is significantly higher than that of adults. Therefore, providing a safe riding environment for children has become a global consensus.

[0003] Although there are many types of child safety seats on the market, most products still have the following problems during use: First, the adjustment function is single. Many child safety seats are fixedly installed, and the adjustment function is limited to the adjustment of the backrest angle or the height of the seat belt. There is a lack of integration of multiple adjustment functions, and it is impossible to fully guarantee the safety and comfort of children in different states; secondly, more and more products introduce electric adjustment functions to improve the convenience of seat adjustment and user experience. However, the excessive proportion of motor drive in child safety seats brings many safety hazards, such as power supply or transmission system failure, weak emergency response capabilities, etc. Based on the above problems, we proposed a child safety seat with multiple adjustment functions, aiming to ensure the safety, stability and ease of use of the seat to better protect the safety of children.

[0054] It should be noted that the rotating slot 101 is opened at the center of the base 1, and the rotating mechanism 2 is inserted along the rotating slot 101 through the rotating pin 203a to connect the two. The positioning holes 102 are evenly distributed around the slot 101. In this embodiment, there are four positioning holes 102, each located in the up, down, left and right directions of the slot 101. By increasing the number of positioning holes 102, more angles of seat position limitation can be achieved.

[0055] Preferably, two sliding rails 201 are provided on the upper surface of the rotating mechanism 2, corresponding to the guide rails 301 of the sliding mechanism 3 respectively. An auxiliary rail 204 is provided between the two sliding rails 201, and is used to limit the position of the sliding mechanism 3 to prevent the sliding mechanism 3 from derailing in the vertical direction. The first handle 202 is installed on both sides of the two sliding rails 201, and the lower chassis 203 is fixedly installed below the rotating mechanism 2. The first handle 202 is installed on both sides of the two sliding rails 201.

[0056] Preferably, the unlocking steps of the rotating mechanism 2 are: pull the first handle 202 - drive the transmission plate 501 - the two locking members 502 separate - the locking button 502a disengages from the button groove 505 - the locking member 502 lifts - the positioning member 503 lifts synchronously - the positioning column 503a lifts - the rotating mechanism 2 is unlocked.

[0057] Preferably, the rotatable angle of the rotating mechanism can be adjusted according to the number of positioning holes 102. For example, if there are 8 positioning holes, the adjustable angles are 45°, 90°, 135°, etc. When the positioning column 503a moves to the corresponding position of the positioning hole 102, it is inserted into the positioning hole 102 under the rebound force of the locking spring 503b, and the first handle 202 is released to check that the safety seat cannot be rotated, and the rotation angle adjustment is completed.

[0058] Preferably, the second handle 304 is engaged with the main body of the sliding mechanism 4 through the protrusion 305. After unlocking, pulling the second handle 304 can pull the entire sliding mechanism 4 to slide along the track.

[0060] Preferably, after the sliding mechanism 3 is unlocked, that is, after the pressing block 601a is pressed, the bite 603b of the block 603 slides from one side of the right-angle protrusion 601b-1 to the other side. Since the other side is a right-angle side, the outer end of the bite 603b will abut against the right-angle protrusion 601b-1. At this time, the pressing block 601a will remain in the pressed state, which can facilitate manual pulling of the sliding mechanism 3 to slide out along the track. Due to the memory function of the block 603, this process There is no need to continue pressing the pressing block 601a. ​​When the sliding mechanism 3 is reset, the limiting protrusion 603c will pass through the bayonet 606. The outer end of the bayonet 606 has a partial slope. During the reset process, the bayonet 606 will gradually lift the limiting protrusion 603c and the block 603, so that the bite of 603b can cross the right-angle protrusion 601b-1 and reset. At the same time, the pressing block 601a is also reset, and the limiting column 602 is reinserted into the column slot 604, and the reset is completed.

[0061] Preferably, in this embodiment, the connecting mechanism 303 is a detachable two-lock structure, which can be used to fix the installation rod 401a-1 and thus connect to the safety seat 4. The function of the protrusion 305 is not only to connect the second handle 304 and the sliding mechanism 3, but also to serve as an unlocking device for the two-lock mechanism. The connecting mechanism 303 can be unlocked by pressing the protrusion 305 from top to bottom, thereby removing or installing the seat.

[0062] Preferably, in this embodiment, the sliding mechanism 3 can only move in one direction, that is, a direction that is convenient for carrying out or placing the child. When the child safety seat of the utility model is installed in the back seat of a car, the best sliding direction is toward the corresponding door, which is convenient for sliding the seat out, thereby making it easier to carry out or place the child, avoiding the inconvenience caused by the parents bending over.

[0063] Preferably, the drive mechanism 401c in the present embodiment is a servo motor drive, which drives the corresponding worm gear by forward and reverse rotation to change the position of the mounting rod 401a-1 in the angle adjustment slot 401b, thereby adjusting the inclination angle of the child safety seat body. After adjusting to a suitable angle, the motor is turned off, the worm gear is fixed, and the seat inclination angle is also fixed accordingly. In addition, in other embodiments of the present invention, the drive mechanism 401c can also be a manual drive device that is adjusted by a dial block or a latch on the outside of the seat.

[0064] In summary, the utility model provides a child safety seat with multiple adjustment functions by integrating multiple adjustment functions. It can flexibly adjust the seat rotation angle, seat position, and seat inclination according to the needs of children of different age groups and body shapes, thereby providing more comprehensive safety protection and comfort experience; in addition, the power design reduces the dependence on motor drive, and through the optimization of the mechanical structure, the seat rotation, position adjustment and other operations are replaced by manual, and is equipped with two sets of independent locking and unlocking methods. This design not only reduces the potential risks of power failure and transmission system failure, but also improves the response capability in emergency situations, and the safety is further improved.
