The structure of the rest of the seat base 1 of the safety seat of the present invention is well known to those skilled in the art and will not be described in detail herein.
In the present invention, the second driving member 140 is installed in the base body 200 and the driving protrusion 141 protrudes from the upper surface of the base body 200, so that the driving protrusion 141 can be driven by a seat body (not shown) installed on the base body, but the second driving member 140 is not limited to the installation position, and may be installed in other parts of the base body, and is not limited to driving by the seat body, as long as it can be driven by the acting force when the seat base is in the use state.
The principle and process of using the safety seat base 1 with the side impact protection mechanism 100 according to the present invention will be described with reference to fig. 1 to 14.
If the safety seat base 1 is not needed, the side impact protection block 110 is folded in the receiving groove 211 of the side wall 210, and the locking protrusion 131 of the locking member 130 protrudes through the through hole 2122 of the protrusion 212 and is clamped in the locking hole 1111 of the side impact protection block 110, thereby locking the side impact protection block 110 in the folded position, as shown in fig. 1-2 and 7-9. At this time, the positioning element 151 is pressed by the sidewall 210 to be retracted into the pivot seat 111 of the side impact protection block 110, and simultaneously presses the third restoring element 152.
When the seat body is mounted on the base body 200, the bottom of the seat body pushes the driving protrusion 141 of the second driving member 140 to drive the second driving member 140 to pivot, the second driving member 140 pulls the locking member 130 through the connection rod 181 and the connection rod 182 to slide along the direction indicated by the arrow F1 in fig. 8-9, and finally the locking protrusion 131 of the locking member 130 is disengaged from the locking hole 1111 of the side impact protection block 110, at this time, the side impact protection block 110 is ejected under the pushing force of the first driving member 120 (torsion spring), and pivots from the retracted position to the open position, as shown in fig. 3-4. In addition, during the pivoting process of the second driving member 140, the first restoring member 170 is deformed, and the sliding of the locking member 130 also deforms the second restoring member 190.
After the side impact protection block 110 is pivoted and ejected, the position of the positioning element 151 on the side impact protection block 110 corresponds to the positioning hole 2121 on the protrusion 212, the positioning element 151 loses the interference effect of the side wall 210, and then is ejected under the action of the third resetting element 152 and is clamped into the positioning hole 2121 on the protrusion 212, and at the moment, the positioning element 151 is in the second position, and the side impact protection block 110 is kept at the unfolding position thereof through the positioning element 151.
When the side impact protection block 110 needs to be folded, the operating portion 162 of the operating element 160 is pulled, so that the operating element 160 slides along the direction indicated by the arrow F2 in fig. 14, at this time, the driving inclined surface 1611 of the operating element 160 interacts with the protrusion 1513 of the positioning element 151, so as to drive the positioning element 151 to slide and disengage from the positioning hole 2121 of the protrusion 212, and in this process, the third resetting element 152 is compressed again. When the positioning member 151 is disengaged from the positioning hole 2121, the side impact protection block 110 can be pushed to pivot to the retracted position shown in fig. 1-2.
Then, the seat body is detached, the driving protrusion 141 of the second driving member 140 loses the pressure of the seat body, so that the driving member is pivotally restored under the action of the first restoring member 170, that is, the driving protrusion 141 protrudes out of the upper surface of the base body 200 again, in this process, the second driving member 140 drives the pull rod 181 and the connecting rod 182 to restore, the locking member 130 receives the acting force of the pull rod 181 and the connecting rod 182 and the restoring deformation acting force of the second restoring member 190, so as to drive the locking member 130 to slide reversely in the direction indicated by the arrow F1 in fig. 8-9, and finally the locking protrusion 131 passes through the through hole 2122 of the protrusion 212 again and is clamped into the locking hole 1111, thereby locking the side impact protection block 110 at the retracted position.
In summary, in the side impact protection mechanism 100 of the present invention, the second driving member 140 is disposed on the base body 200 of the safety seat base 1 and connected to the locking member 130, and the second driving member 140 can be stressed when the safety seat base 1 is in a use state, so as to drive the locking member 130 to slide and release the locking of the side impact protection block 110, at this time, the side impact protection block 110 is automatically pivoted to the unfolding position under the driving of the first driving member 120, that is, the side impact protection block 110 can be automatically opened when the safety seat base 1 is in use, so as to achieve the due protection effect, and the side impact protection block 110 can be folded to reduce the occupied lateral space when the side impact protection block is not in use.
Correspondingly, the safety seat base 1 having the side impact protection mechanism 100 of the present invention also has the same technical effects.
The above disclosure is only for the preferred embodiment of the present invention, and it should be understood that the present invention is not limited thereto, and the invention is not limited to the above disclosure.
