[0038] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] An embodiment of the present application discloses a child safety seat, which includes a base, a seat, and a translation mechanism. The seat is disposed on the base through the translation mechanism, and the seat can be translated relative to the base through the translation mechanism.

[0040] Referring to Figures 1 to 4 , the translation mechanism includes a moving base 10, a moving platform 20, and a magnetic component 30. The moving base 10 is fixed on the base, and the moving platform 20 is slidably disposed on the moving base 10 and is used to carry the seat, that is, the seat is fixed on the moving platform 20. The magnetic component 30 includes a first magnetic strip 31 and a second magnetic strip 32. The first magnetic strip 31 and the second magnetic strip 32 are respectively fixed on one side of the moving base 10 and the moving platform 20 facing each other. For example, the first magnetic strip 31 is fixed on the surface of the moving base 10 facing the moving platform 20, and the second magnetic strip 32 is fixed on the surface of the moving platform 20 facing the moving base 10. The length directions of the first magnetic strip 31 and the second magnetic strip 32 are the same as the sliding direction of the moving platform 20 relative to the moving base 10, that is, the first magnetic strip 31 and the second magnetic strip 32 are parallel and the same as the sliding direction of the moving platform 20 relative to the moving base 10. The first magnetic strip 31 and the second magnetic strip 32 face each other, and the polarities of the sides of the first magnetic strip 31 and the second magnetic strip 32 facing each other are the same.

[0041] In this way, by fixing the first magnetic strip 31 and the second magnetic strip 32 of the magnetic component 30 on one side of the moving base 10 and the moving platform 20 facing each other, and the polarities of the sides of the first magnetic strip 31 and the second magnetic strip 32 facing each other are the same, a repulsive force will be generated between the first magnetic strip 31 and the second magnetic strip 32, thereby reducing the pressure of the moving platform 20 relative to the moving base 10, and further reducing the friction force between the two. In this way, when the seat is translated, it is more labor-saving, smooth, and improves the experience.

[0042] Of course, in specific use, the translation direction can be the side direction of the vehicle or the depth direction of the vehicle seat for translation, and the specific translation direction is selected according to actual needs.

[0043] Specifically, in combination with Figure 2 , Figure 4 and Figure 5 , the moving base 10 is provided with an installation long groove 11, the moving platform 20 is located in the installation long groove 11, and can perform reciprocating linear motion along the groove length direction of the installation long groove 11, so that the moving platform 20 can sink into the moving base 10, reducing the total height of the two, and also improving the sliding installation stability of the moving platform 20. The corresponding magnetic component 30 is between the bottom surface of the moving platform 20 and the bottom of the installation long groove 11, and the length directions of the first magnetic strip 31 and the second magnetic strip 32 are the same as the groove length direction of the installation long groove 11.

[0044] In combination with Figure 6 , the magnetic component 30 includes at least two first magnetic strips 31 and at least two second magnetic strips 32. Each first magnetic strip 31 faces a second magnetic strip 32, and the first magnetic strips 31 and the second magnetic strips 32 are all spaced along the groove width direction of the installation long groove 11 to uniformly provide repulsive force.

[0045] In order to prevent the moving platform 20 from flipping out of the installation long groove 11 due to excessive repulsive force, two limiting plates 12 are provided on the moving base 10. The two limiting plates 12 are respectively located on both sides of the groove width direction of the installation long groove 11, and part of the limiting plate 12 covers the groove opening of the installation long groove 11. The part of the limiting plate 12 covering the groove opening of the installation long groove 11 is used for sliding cooperation with the moving platform 20. In this way, if the repulsive force provided by the magnetic component 30 is too large, the limiting plate 12 will slide into contact with the upper surface of the moving platform 20 (that is, the side of the moving platform 20 exposed at the groove opening of the installation long groove 11) to prevent the moving platform 20 from flipping out without affecting the translation of the moving platform 20.

[0046] Furthermore, in combination with Figure 7 , the two sides of the moving platform 20 are respectively provided with limiting parts 21 extending laterally. The limiting parts 21 are used for sliding cooperation with the limiting plates 12, which can reduce the width of the moving platform 20, save the material of the moving platform 20, and reduce the manufacturing cost.

[0047] In order to ensure that the moving platform 20 can perform precise reciprocating linear motion in one direction relative to the moving base 10, in combination with Figure 8, therefore, a guiding long groove 13 is provided at the bottom of the installation long groove 11 of the moving base 10, and the moving platform 20 is provided with a guiding sliding plate 22 that slidably cooperates with the guiding long groove 13. The length directions of the guiding long groove 13 and the guiding sliding plate 22 are both the same as the sliding direction of the moving platform 20 relative to the moving base 10.

[0048] Specifically, the guiding long groove 13 includes a first guiding groove 14 and a second guiding groove 15 provided at the bottom of the first guiding groove 14. The guiding sliding plate 22 includes a guiding body 23 and a guiding strip 24 connected to the guiding body 23. The guiding body 23 slidably cooperates with the first guiding groove 14, and the guiding strip 24 slidably cooperates with the second guiding groove 15. In this way, the translation direction of the moving platform 20 is jointly defined by the cooperation of the first guiding groove 14 and the guiding body 23 and the cooperation of the second guiding groove 15 and the guiding strip 24, making the linearity of the movement of the moving platform 20 better.

[0049] Of course, the number of the second guiding grooves 15 can be one or at least two, and the number of the guiding strips 24 is the same as the number of the second guiding grooves 15. Each guiding strip 24 slidably cooperates with one second guiding groove 15.

[0050] On the opposite sides of the moving base 10 and the moving platform 20 facing each other, a first fixed long groove 16 and a second fixed long groove 25 are respectively provided. That is to say, on the side of the moving base 10 facing the moving platform 20, the first fixed long groove 16 is provided, specifically at the bottom of the installation long groove 11. On the side of the moving platform 20 facing the moving base 10, the second fixed long groove 25 is provided. The first magnetic strip 31 is installed in the first fixed long groove 16 to be embedded in the moving base 10, and the second magnetic strip 32 is installed in the second fixed long groove 25 to be embedded in the moving platform 20. In this way, the structural compactness can be improved.

[0051] Combined Figure 9 , in order to make the translation more labor-saving, a driving component 40 can be used to drive the moving platform 20 to translate. That is to say, the translation mechanism further includes a driving component 40 provided on the moving base 10. The driving component 40 is connected to the moving platform 20 and is used to drive the moving platform 20 to slide relative to the moving base 10.

[0052] Specifically, the driving component 40 includes a telescopic motor and a transmission member. The telescopic motor is fixed to the bottom of the installation long groove 11 of the moving base 10, and the telescopic motor is connected to the moving platform 20 through the transmission member. Among them, the type of the transmission member is not specifically limited as long as it can transmit the power of the rotor of the telescopic motor to the moving platform 20.

[0053] To facilitate the installation of the drive assembly 40, a clearance space 50 can be formed between the mobile platform 20 and the mobile base 10. The drive assembly 40 is located within the clearance space 50. Among them, the mobile platform 20 can be provided with a through window 26, and the window 26 communicates with the clearance space 50, so that the height of the clearance space 50 can be increased while ensuring that the height increase of the translation mechanism remains unchanged.

[0054] Of course, in some embodiments, the drive assembly 40 can also be a linear motor, whose stator is fixed to the bottom of the installation slot 11 of the mobile base 10, and the mover is connected to the mobile platform 20.

[0055] In summary, the embodiments of the present application disclose a translation mechanism and a child safety seat. By fixing the first magnetic strip 31 and the second magnetic strip 32 of the magnetic assembly 30 on the opposite sides of the mobile base 10 and the mobile platform 20 facing each other, and the polarities of the opposite sides of the first magnetic strip 31 and the second magnetic strip 32 are the same, a repulsive force will be generated between the first magnetic strip 31 and the second magnetic strip 32, thereby reducing the pressure of the mobile platform 20 relative to the mobile base 10, and further reducing the friction between the two. In this way, when the seat is translated, it is more labor-saving, smooth, and improves the experience.

[0056] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
