Technical Field
[0001] The utility model relates to a child safety seat with an electric adjustment mechanism. Background Art
[0002] In existing child safety seat designs, seat angle adjustment is a key feature that allows the seat to be tilted according to the child's body shape and riding comfort requirements. However, traditional adjustment mechanisms usually have some limitations that affect the convenience and accuracy of seat adjustment.
[0003] The adjustment mechanism of traditional child safety seats often uses manual rotation or turning to adjust the angle. The manual adjustment method is not only inconvenient, especially when one-handed operation is required or in an emergency. In addition, the manual adjustment method has poor accuracy and is difficult to achieve subtle angle adjustments, which affects riding comfort. In addition, the reliability and durability of the manual adjustment mechanism are also insufficient under long-term use and frequent adjustments.
[0004] With the improvement of automobile safety standards and parents' increasing attention to children's safety in cars, the market has put forward higher requirements on the performance of child safety seats. There is an urgent need for a seat angle adjustment mechanism and a child safety seat with simple structure, convenient operation and precise adjustment. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0034] It should be noted that in the claims and description of this patent, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprises a" do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0035] like Figure 1 and Figure 2 As shown, this embodiment discloses a method as Figure 3 The child safety seat shown in the figure uses an electric adjustment mechanism, which includes a base 1 , a drive rod 2 , a motor drive assembly 3 , and a driven member 4 .
[0036] The base 1 is mounted on the base 7 of the child safety seat.
[0037] In this embodiment, the driving rod 2 is a rod-shaped structure, but is not limited thereto.
[0038] The motor drive assembly 3 is mounted on the base 1 and connected to the drive rod 2 . The motor drive assembly 3 is configured to be able to drive the drive rod 2 to rotate around its axis.
[0039] The follower 4 is connected to the driving rod 2 and to the component whose position is to be adjusted. The follower 4 is configured to be able to move forward and backward along the axial direction of the driving rod 2 as the driving rod 2 rotates to adjust the position of the component to be adjusted. The component to be adjusted may be a seat or backrest of a child safety seat, etc.
[0040] In this embodiment, the driving rod 2 is a structure having an external thread, and the driven member 4 is a structure having an internal thread that can be connected to the external thread of the driving rod 2 .
[0041] In this embodiment, the number of turns and pitch of the thread define the adjustment range and step size of the follower 4, making the adjustment process more precise. The threaded connection has a certain self-locking property, which can maintain the current adjustment position when the motor is turned off to prevent the adjusted component from sliding.
[0042] In other alternative embodiments, the driving rod 2 is a worm structure, and the driven member 4 is a worm gear structure meshed with the driving rod 2. The meshing of the worm and the worm gear can provide a higher force transmission efficiency, so that a smaller motor can also drive a larger load. The precise meshing of the worm and the worm gear can achieve precise control of the position of the driven member 4. In addition, the worm gear transmission has a self-locking characteristic, which can prevent the driven member 4 from reversing or sliding down.
[0043] The electric adjustment mechanism of this embodiment further includes a sensor 5 for detecting the position of the follower 4 to improve the adjustment accuracy. Furthermore, in this embodiment, the sensor 5 is a travel switch, and the number of the travel switches is two, which are respectively arranged at both ends of the movement path of the follower 4, so as to further ensure the accuracy of the electric adjustment.
[0044] In addition, the electric adjustment mechanism of this embodiment also includes a component rotation structure 6 connecting the follower 4 and the position to be adjusted, so that the movement trajectory of the component to be adjusted is not limited to linear movement completely along the axial direction of the driving rod 2, thereby improving the applicability of the electric adjustment mechanism of this embodiment.
[0045] The child safety seat of this embodiment adopts the electric adjustment structure of this embodiment, which can adjust the angle by electric means, and no longer needs to be adjusted manually. The electric adjustment method is not only convenient and fast, but also has high adjustment accuracy, and can achieve subtle angle adjustment, thereby improving riding comfort. In addition, the reliability and durability of the electric adjustment mechanism are also more reliable under the condition of long-term use and frequent adjustment.
