[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0038] Child safety seats are typically installed in the rear seats of a car to protect children's safety. A child safety seat generally includes a child seat back, a child seat base, and seat support legs. The rear end of the child seat base connects to the rear seat of the car, and the front end of the child seat base has seat support legs, which are supported on the car floor to ensure the stability of the child safety seat when installed in the rear seat of the car.

[0039] However, existing seat support legs often only fit the height of one type of rear seat in a car, resulting in poor versatility.

[0040] To resolve the above technical issues, please refer to Figure 1 and Figure 2This application provides a child safety seat 1000, which may include a seat base 200 and a seat support leg 100. The lower surface of the seat base 200 is formed with a storage groove, and one end of the seat support leg 100 extends into the storage groove and is rotatably connected to the bottom wall of the storage groove.

[0041] The seat support leg 100 includes a storage position and a use position, and the seat support leg 100 can rotate between the use position and the storage position. When the seat support leg 100 is in the storage position, it is located in the storage recess, reducing the space occupied by the child safety seat 1000 when it is not in use. When the seat support leg 100 is in the use position, it rotates relative to the seat base 200 until the ground end abuts against the vehicle floor, providing support for the child safety seat 1000.

[0042] Please refer to Figures 3 to 5 The seat support leg 100 may include a first rod 110, a second rod 120, and a locking element 130.

[0043] The first rod 110 can be a solid rod or a hollow rod. Taking the first rod 110 as a hollow rod, the peripheral wall of the first rod 110 is provided with a plurality of first positioning holes 111. The plurality of first positioning holes 111 are spaced apart in the extension direction of the first rod 110. The first rod 110 is formed into a first end and a second end 112 at both ends in its extension direction.

[0044] The second rod 120 is formed as a hollow rod. The two ends of the second rod 120 in its extension direction are respectively formed as a first port and a second port. The first rod 110 passes through the first port into the second rod 120 and can move along the extension direction of the second rod 120. The first end is located inside the second rod 120, and the second end 112 is located outside the second rod 120. The second positioning hole 121 is provided on the circumferential outer side of the second rod 120. During the movement of the first rod 110, the multiple first positioning holes 111 can be aligned with the second positioning hole 121.

[0045] The locking element 130 may include a fixed base 131, an adjusting element 132, and a positioning pin 133.

[0046] The fixed base 131 includes a base body 1311 and a functional wall 1312. The base body 1311 is cylindrical and is sleeved on the outer circumferential side of the second rod 120. The base body 1311 is provided with a third positioning hole 1313 opposite to the second positioning hole 121. The functional wall 1312 can be formed in an annular shape. The functional wall 1312 is provided on the outer wall surface of the base body 1311 and extends radially outward toward the second rod 120. The functional wall 1312 surrounds the third positioning hole 1313.

[0047] The adjusting member 132 is surrounded by an annular functional wall 1312. The adjusting member 132 is formed into a long strip shape. The adjusting member 132 is provided with a rotating shaft 1324 and a connecting part 1325. The rotating shaft 1324 and the connecting part 1325 are spaced apart in a first direction. The functional wall 1312 is provided with a rotating hole. The rotating shaft 1324 passes through the rotating hole, so that the adjusting member 132 rotates around the rotating shaft 1324. The first direction is perpendicular to the rotation axis of the adjusting member 132. The first direction can be the extension direction of the second rod 120, that is, the length direction of the adjusting member 132.

[0048] One end of the positioning pin 133 is rotatably connected to the connecting part 1325, and the other end can extend into or pull out of the first positioning hole 111. It can be understood that by adjusting the member 132 rotating around the rotating shaft 1324, the connecting part 1325 drives the positioning pin 133 to move towards or away from the radially inward side of the first rod 110, thereby realizing the positioning pin 133 extending into or pulling out of the first positioning hole 111, realizing the locking and disengagement of the second rod 120 and the first rod 110.

[0049] In this way, since the first rod 110 can move relative to the second rod 120 along its extension direction, different first positioning holes 111 and second positioning holes 121 are aligned. The different first positioning holes 111 and second positioning holes 121 are locked by the positioning pin 133, so that the seat support leg 100 can be maintained at different lengths. This allows the seat support leg 100 to adapt to the requirements of the rear seats of different cars, improving the applicability of the child safety seat 1000.

[0050] Specifically, in the length direction of the adjusting member 132, the adjusting member 132 includes a pressing section 1321, a rotating shaft section 1324 1322 and a connecting section 1323 in sequence. The rotating shaft 1324 is located on both sides of the rotating shaft section 1324 1322 in the width direction of the adjusting member 132 and passes through the rotating hole on the functional wall 1312. The connecting part 1325 is provided with the connecting section 1323. The pressing section 1321 is spaced apart from the seat body 1311.

[0051] It can be understood that, in this way, the pressing section 1321 and the connecting section 1323 form a seesaw structure. Pressing the pressing section 1321 causes it to move toward the seat body 1311, while the connecting section 1323 moves away from the seat body 1311. This allows the positioning pin 133 to be pulled out of the first positioning hole 111, causing the first rod 110 to disengage from the second rod 120. This enables the extension and retraction adjustment of the first rod 110 and the second rod 120, allowing the seat support leg 100 to be adjusted to different lengths.

[0052] When the seat support leg 100 is adjusted to a suitable length, the connecting section 1323 can be pressed to allow the positioning pin 133 to extend into the first positioning hole 111 of the corresponding length, thereby locking the first rod 110 and the second rod 120 at the new length position, so that the seat support rod is maintained at that length.

[0053] Furthermore, the locking member 130 may also include an elastic member 134, which is sandwiched between the pressing section 1321 and the seat body 1311. The elastic member 134 always applies a pushing force to the pressing section 1321 away from the seat body 1311. Thus, when the user removes the pressing force on the pressing section 1321, under the action of the elastic member 134, the pressing section 1321 moves in the direction away from the seat body 1311, and the connecting section 1323 moves in the direction towards the seat body 1311, so that the positioning pin 133 extends into the first positioning hole 111 and the second positioning hole 121, locking the first rod 110 and the second rod 120.

[0054] Among them, the elastic element 134 can be a spring.

[0055] In some embodiments of this application, the pressing section 1321 is provided with a pressing groove 1326. The pressing groove 1326 is recessed from the side surface of the pressing section 1321 away from the pressing section 1321 toward the seat body 1311. In this way, by providing the pressing groove 1326, a pressing position is provided for the user, so that the user can identify the position of the pressing section 1321 and it is convenient for the user to apply force to start the adjustment member 132 to rotate.

[0056] In some embodiments of this application, the seat support leg 100 may further include a limiting portion 140, which is disposed at the first end and extends out of the outer peripheral wall of the first rod 110; the seat body 1311 extends to the first port at one end and is folded radially inward toward the first port to form a flange 1314, and the projection of the limiting portion 140 in the extension direction of the first rod 110 at least partially intersects with the flange 1314.

[0057] Specifically, the limiting part 140 is engaged at the first end. The limiting part 140 includes a locking plate 141, the edge of which extends out of the outer peripheral wall of the first rod 110. In this way, when the first rod 110 is about to slide out of the second rod 120, the locking plate 141 of the limiting part 140 will abut against the flange 1314, thereby preventing the first rod 110 from sliding out of the second rod 120 and ensuring the stability of the seat support leg 100 during use.

[0058] In some embodiments of this application, the projection of the second end 112 in the extension direction of the first rod 110 is at least partially located outside the first port. Specifically, the second end 112 is formed in a rectangular shape, and the cross-sectional area of ​​the second end 112 is much larger than the cross-sectional area of ​​the second rod 120.

[0059] In this way, on the one hand, the first lever 110 can be prevented from completely entering the interior of the second lever 120, thus affecting the subsequent reuse of the seat support leg 100. On the other hand, the second end 112 is the position where the seat support leg 100 abuts against the car floor, which can increase the contact area between the seat support leg 100 and the vehicle floor, thereby increasing the stability of the child safety seat 1000 during use.

[0060] In some embodiments of this application, please refer to Figure 5 and Figure 6 The seat support leg 100 may also include a seat connecting part 150, which is located at the second port and is used to rotatably connect with the seat base 200.

[0061] Specifically, the end face of the seat connecting part 150 opposite to the second port is provided with a fixing protrusion 151, and the seat base 200 is provided with a fixing member 300. The fixing member 300 is located in the storage groove and has a fixing groove. When the seat support leg 100 is in the use position, the fixing protrusion 151 can be inserted into the fixing groove, so that the seat support leg 100 can be fixed in the use position.
