[0069] Further, in order to reduce the weight of the guide 23 while increasing the strength of the guide 23, in some embodiments, the plurality of weight-reducing holes 234 are arranged along the contour shape of the guide 23. In this way, the guide 23 has a smaller weight and a higher strength.

[0070] Please refer to Figure 11 In the embodiment, the contour shape of the guide 23 is close to an isosceles trapezoid, and therefore, in the embodiment, the plurality of weight-reducing holes 234 can be arranged along the contour of an isosceles trapezoid. Here, the arrangement of the plurality of weight-reducing holes 234 is not specifically limited.

[0071] Further, in order to increase the strength of the guide 23, in some embodiments, the diameter of the weight-reducing hole 234 is a second size, which is greater than or equal to 1.2 times the first size and less than or equal to 2 times the first size. In this way, while the weight-reducing hole 234 is arranged, the size of the weight-reducing hole 234 can be prevented from affecting the strength of the guide 23, so that the guide 23 has a lighter weight and a stronger strength.

[0072] Please refer to Figures 12-15 shown, Figure 12 a plan view of an operating member in a child safety seat provided in the embodiment of the application, Figure 13 a perspective view of an operating member in a child safety seat provided in the embodiment of the application, Figure 14 is Figure 13 a sectional view along the direction of B-B, Figure 15 is Figure 14 an enlarged view of a local structure at C in the embodiment. In some embodiments, the handle portion 61 has a first cooperating portion 611 and a second cooperating portion 612 cooperating with the seat body 1, the first cooperating portion 611 is connected to the front side of the second cooperating portion 612, the side of the first cooperating portion 611 facing the seat body 1 forms a first cooperating surface 6111, the side of the second cooperating portion 612 facing the seat body 1 forms a second cooperating surface 6121, and the first cooperating surface 6111 and the second cooperating surface 6121 are both in sliding cooperation with the seat body 1.

[0073] In order to improve the operation space at the handle part 61, in some optional embodiments, the included angle between the first fitting surface 6111 and the second fitting surface 6121 is obtuse.

[0074] Further, in order to make the operation space between the first fitting part 611 and the second fitting part 612 larger, in some embodiments, the included angle between the first fitting surface 6111 and the second fitting surface 6121 ranges from 93 degrees to 100 degrees. In this way, the operation space at the handle part 61 can be further improved to facilitate holding the handle part 61.

[0075] For example, the included angle between the first fitting surface 6111 and the second fitting surface 6121 can be 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, 99 degrees, 100 degrees, etc. Here, the included angle between the first fitting surface 6111 and the second fitting surface 6121 is not limited specifically.

[0076] In some specific embodiments, the included angle between the first fitting surface 6111 and the second fitting surface 6121 can be 94 degrees.

[0077] In order to make the first fitting part 611 have sufficient length to facilitate holding the handle part 61, in some optional embodiments, the size of the first fitting part 611 in the extension direction of the first fitting surface 6111 ranges from 35 mm to 50 mm, wherein the extension direction of the first fitting surface 6111 is consistent with the x-x axis direction in Figure 12 and Figure 13 In this way, the length of the first fitting part 611 is larger, which facilitates holding the handle part 61, and further improves the operation experience of the operation piece 6.

[0078] In the process of pulling the operation piece 6, the operation of the operation piece 6 may not be smooth due to the large friction between the operation piece 6 and the seat body 1, therefore, in some embodiments, the operation smoothness of the operation piece 6 can be improved by reducing the friction between the operation piece 6 and the seat body 1.

[0079] In the embodiment, the first sliding rib 613 protruding towards the seat body 1 can be arranged on the side of the second matching surface 6121 facing the seat body 1, and the first sliding rib 613 is in sliding cooperation with the seat body 1 and extends along the extension direction of the second matching surface 6121. In this way, the second matching part 612 and the seat body 1 are in linear contact, which can reduce the friction between the second matching part 612 and the seat body 1, thereby improving the smoothness of the operation of the operating member 6. In the embodiment, the first sliding rib 613 protruding towards the seat body 1 can be arranged on the side of the second matching surface 6121 facing the seat body 1, and the first sliding rib 613 is in sliding cooperation with the seat body 1 and extends along the extension direction of the second matching surface 6121. In this way, the second matching part 612 and the seat body 1 are in linear contact, which can reduce the friction between the second matching part 612 and the seat body 1, thereby improving the smoothness of the operation of the operating member 6.

[0080] Figure 12 It should be noted that the extension direction of the second matching surface 6121 is consistent with the y-y axis direction in Figure 13

[0081] In order to further reduce the friction between the second matching part 612 and the seat body 1, in some optional embodiments, the first sliding rib 613 is a plurality of first sliding ribs 613, and the plurality of first sliding ribs 613 are arranged in the width direction of the seat body 1. In this way, the friction between the second matching part 612 and the seat body 1 can be further reduced, and the smoothness of the operation of the operating member 6 can be improved.

[0082] Since the space for the operating member 6 is limited, the protruding height of the first sliding rib 613 should be appropriate, and in some optional embodiments, the protruding height of the first sliding rib 613 is less than or equal to 2 mm. In this way, the space arrangement of the operating member 6 itself can be avoided due to the arrangement of the first sliding rib 613.

[0083] For example, the protruding height of the first sliding rib 613 can be 2 mm, 1.9 mm, 1.8 mm, 1.7 mm, 1.6 mm, 1.5 mm, 1.4 mm, 1.3 mm, 1.2 mm, 1.1 mm, 1.0 mm, etc. Here, the protruding height of the first sliding rib 613 is not limited.

The third matching surface 152 is provided with a second sliding rib 153 protruding towards the second matching surface 6121. The second sliding rib 153 is in sliding cooperation with the second matching surface 6121. The extension direction of the second sliding rib 153 is the same as that of the first sliding rib 613. The second sliding rib 613 and the first sliding rib 613 are distributed in a staggered manner in the width direction of the seat body 1. Since it is not convenient to form more first sliding ribs 613 on the second matching surface 6121, the excess sliding ribs are arranged on the third matching surface 152 to form the second sliding rib 153, so that the friction between the second matching part 612 and the seat bottom cover 15 is small, and the normal forming of the operation member 6 and the seat bottom cover 15 is not affected.

[0086] In order to further reduce the friction between the second matching part 612 and the seat bottom cover 15, the above-mentioned second sliding rib 153 can be a plurality of second sliding ribs 153 arranged in a spaced manner in the width direction of the seat body 1. In this way, the friction between the second matching part 612 and the seat bottom cover 15 can be further reduced, and the operation smoothness of the operation member 6 can be improved.

[0087] In order to avoid a large gap between the second matching part 612 and the seat bottom cover 15 and increase the occupied space of the child safety seat 10 provided by the embodiment, in some optional embodiments, the protruding height of the second sliding rib 153 is less than or equal to 1 mm. In this way, by limiting the protruding height of the first sliding rib 613 and the second sliding rib 153, the friction between the second matching part 612 and the seat bottom cover 15 can be reduced, the operation smoothness of the operation member 6 can be improved, and the space occupied by the operation member 6 and the seat bottom cover 15 can be reduced. That is, the arrangement of the first sliding rib 613 and the second sliding rib 153 will not increase the occupied space of the child safety seat 10 provided by the embodiment, so that the use performance of the child safety seat 10 provided by the embodiment can be further improved.
