Example one
As shown in fig. 1-7, the present embodiment provides a child safety seat including a base 1, legs 2, and a seat portion 3.
The base 1 is used for bearing the seat part 3, and the bottom of the base 1 is provided with a flat base bottom surface 13. The front part of the base 1 is provided with a base front end face 14, and the bottom of the base is also provided with a supporting leg accommodating cavity 11. The leg receiving cavity 11 has a lower opening 113 located on the base bottom surface 13 and a front opening 114 located on the base front end surface 14, and the front opening 114 is communicated with the lower opening 113.
The child safety seat further comprises a leg 2 having a central axis 25, the leg 2 being pivotally connected to the front of the base 1 by a pivot axis 22. The legs 2 have a folded working position and an unfolded working position. When the leg 2 is in the folded working position, the leg 2 is received in the leg receiving cavity 11 and the leg 2 is located entirely above the base bottom surface 13; when the legs 2 are in the open working position, the legs 2 stand vertically below and in front of the base 1. Parents choose different working positions according to the actual requirements of children in different age groups.
The end part of the supporting leg 2 close to the rotating shaft 22 is provided with a stop block 21 which extends towards one side of the supporting leg 2 to form a bulge; when the supporting leg 2 is in the folding working position, the stop block 21 protrudes towards the upper side of the supporting leg 2, the rotating shaft 22 is positioned on the stop block 21 above the central axis 25 of the supporting leg, and the stop block 21 blocks the front opening 114 of the front end surface 14 of the base; when the leg 2 is in the open operating position, the stop 21 projects laterally rearward of the leg 2, and the pivot axis 22 is located on the stop 21 rearward of the central axis 25 of the leg 2. When the leg 2 is switched between the folded working position and the unfolded working position, the leg 2 is rotated relative to the base 1 about the rotation shaft 22, and the axis line of the rotation shaft 22 extends in the left-right direction.
When the leg 2 is in the folded working position, the front face 211 of the stop 21 is flush with the front face 14 of the base, where the flush may be, in addition to being perfectly aligned, either the front face 211 of the stop 21 protruding slightly from the front face 14 of the base or the front face 211 of the stop 21 slightly recessed from the front face 14 of the base.
The stopper 21 blocks the front opening 114 of the front end surface 14 of the base, and a gap on the surface of the safety seat is avoided, so that the situation that a child clamps a finger between the base 1 and the supporting leg 2 is avoided, the safety of the child seat is improved, and potential danger is reduced.
The front part of the leg receiving cavity 11 is a block receiving cavity 111, the upper side of the inner wall of the block receiving cavity 111 is an arc surface 112 taking the rotating shaft 22 as an axis, and the block receiving cavity 111 below the arc surface 112 provides a space for the rotation of the block 21. The front of the arcuate surface 112 is a front opening 114. The block accommodating cavity 111 is communicated with the support leg accommodating cavity 11, and the block 21 is positioned in the block accommodating cavity 111 and rotates along with the change of the working position of the support leg 2 in the block accommodating cavity 111.
The base 1 is also provided with a limit stop lever 12, the limit stop lever 12 is positioned at the rear part of the rotating shaft 22, when the supporting leg 2 is in the opening working position, the limit stop lever 12 abuts against the bottom of the stop block 21 to limit the supporting leg 2 from excessively rotating in the counterclockwise direction (as shown in figure 3); the bottom of the stop 21 is disengaged from the limit stop 12 when the leg 2 is in the folded working position. When the child safety seat is impacted by accident, the limit stop lever 12 can prevent the landing leg 2 in the opening working position from turning over anticlockwise, so that the stability of the child safety seat is enhanced.
The bottom of the stop 21 is provided with an arc-shaped groove 212 with a downward opening, and when the support leg 2 is in the opening working position, the limit stop lever 12 abuts against the arc-shaped groove 212. The arcuate slot 212 may further stabilize the leg 2 in the open operative position.
The leg 2 in this child safety seat has a first support section 23 and a second support section 24, the first support section 23 being slidably connected to the second support section 24. The second support section 24 may extend partially or completely from the first support section 23, the extension of the second support section 24 being adjusted according to the height difference between the floor of the vehicle and the child safety seat to provide better support for the child safety seat.
Example two
As shown in fig. 8 to 12, the present embodiment is different from the first embodiment in that a first locking mechanism 4 is provided between the leg 2 and the base 1, and the first locking mechanism 4 locks the leg 2 and the base 1 in the open working position. As shown in fig. 11, the stopper 21 has a side wall provided with a lock shaft 43, and a side wall of the stopper housing cavity 111 has a first lock groove 41 and a second lock groove 42. When the leg 2 is in the open working position, the locking shaft 43 is inserted in the first locking groove 41. When the leg 2 is in the folded working position, the locking shaft 43 is disengaged from the first locking groove 41, and the locking shaft 43 is inserted in the second locking groove 42.
As shown in fig. 9-10, a second locking mechanism 5 is further provided between the leg 2 and the base 1, and the second locking mechanism 5 locks the leg 2 and the base 1 in the folded working position. A lock groove 51 is formed above the rear end of the leg housing cavity 11 of the base 1, and a lock head 52 is provided at the lower end of the leg 2. When the leg 2 is in the folded working position, the locking head 52 is inserted into the locking groove 51 to lock the leg 2 in the folded working position. When the legs 2 are transferred from the folded working position to the unfolded working position, the locking head 52 is disengaged from the locking groove 51.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
