Referring to fig. 8 and 9, the multi-stage side impact protection device 20 includes an energy absorbing mechanism 21, an elastic member 23, and a force receiving mechanism 22. The force-receiving mechanism 22 includes two selectively foldable or unfoldable protective blocks, which are named as a first protective block 22a and a second protective block 22b along the opposite directions of side impact (i.e., the opposite directions indicated by the arrow a) for convenience of description. The force-bearing mechanism 22 has an extended position shown in fig. 2 and a retracted position shown in fig. 1 relative to the back-rest side wings 10; specifically, in the present embodiment, the first protection block 22a is movably assembled to the backrest side wings 10 and has an unfolding position and a folding position relative to the backrest side wings 10, but is not limited thereto. The energy absorbing mechanism 21 is preferably a buffer stop to simplify the structure, but not limited thereto, and the energy absorbing mechanism 21 is movably disposed on the first protection block 22a and selectively allows or blocks the first protection block 22a and the second protection block 22b from being folded with each other, the elastic member 23 is connected to the energy absorbing mechanism 21 and the first protection block 22a, the elastic member 23 constantly has a position for driving the energy absorbing mechanism 21 to move to block the first protection block 22a and the second protection block 22b from being folded with each other, as shown in fig. 7; of course, the energy absorption mechanism 21 is movably disposed on the second protection block 22b according to actual needs, and the elastic member 23 is connected to the second protection block 22b and the energy absorption mechanism 21, so the invention is not limited thereto.
As shown in fig. 2 or fig. 7, when the force-receiving mechanism 22 is located at the unfolding position, the force-receiving mechanism 22 protrudes from the surface 11 of the backrest side wing 10, as shown in fig. 2, so that the volume of the force-receiving mechanism 22 at the folding position is smaller than the volume of the force-receiving mechanism 22 at the unfolding position; specifically, when the first protection block 22a is located at the extended position shown in fig. 2 or fig. 7, the first protection block 22a and the second protection block 22b are extended from each other at this time, so that the energy absorption mechanism 21 moves to a position where the first protection block 22a and the second protection block 22b are blocked from being folded from each other, so that the first protection block 22a and the second protection block 22b form a primary side impact stroke protruding from the surface 11 of the backrest 10, which is shown in fig. 2; when the first protection block 22a is in the extended position as shown in fig. 2 or fig. 7 and the operation moves the energy absorption mechanism 21 to the position allowing the first protection block 22a and the second protection block 22b to be folded, the first protection block 22a and the second protection block 22b are folded, so that the first protection block 22a and the second protection block 22b form a secondary side collision stroke protruding from the surface 11 of the backrest side wing 10. For example, in the present embodiment, the first protection block 22a and the second protection block 22b are in sleeved fit with each other, so that the second protection block 22b covers the first protection block 22a, and certainly, the first protection block 22a covers the second protection block 22b according to actual needs; the energy absorbing mechanism 21 is slidably disposed on the first protection block 22a, and correspondingly, the elastic element 23 is selected to be an extension spring or a compression spring, but in other embodiments, the energy absorbing mechanism 21 is pivotally connected to the first protection block 22a according to actual needs, and correspondingly, the elastic element 23 is selected to be a torsion spring, so the invention is not limited thereto.
During the side impact process of the primary side impact stroke, the first protection block 22a and the second protection block 22b are mutually folded to force the energy absorption mechanism 21 to move to a position allowing the first protection block 22a and the second protection block 22 to be folded, and naturally, the energy absorption mechanism 21 is forced to deform to absorb and buffer the side impact energy; specifically, in the present embodiment, the inner wall 224 of the second protection block 22b forces the energy absorption mechanism 21 to slide along the inner wall 224 to a position allowing the first protection block 22a and the second protection block 22b to be folded, that is, the inner wall 224 pushes the energy absorption mechanism 21 to perform retraction sliding, and the elastic member 23 generates elastic deformation to enable the energy absorption mechanism 21 to slide to a position blocking the first protection block 22a and the second protection block 22b from being folded, and of course, the inner wall 224 of the second protection block 22b forces the energy absorption mechanism 21 to deform to absorb and buffer the impact energy; when the force-receiving mechanism 22 (specifically, the first protection block 22a) is located at the retracted position shown in fig. 1, the first protection block 22a and the second protection block 22b are retracted along the side impact direction (i.e., indicated by the arrow a) so that the second protection block 22b is flush with the surface 11 of the backrest side wing 10, so that the safety seat 100 is more beautiful. More specifically, the following:
as shown in fig. 4 and 8, the first protection block 22a and the second protection block 22b are respectively pivoted with the back-rest wing 10, so that the first protection block 22a and the second protection block 22b are pivoted with the back-rest wing 10, of course, the first protection block 22a is slidably disposed on the back-rest wing 10 according to actual requirements, and the second protection block 22b is slidably disposed on the first protection block 22a, so as to realize mutual folding or unfolding between the first protection block 22a and the second protection block 22 b; specifically, in the present embodiment, the first protection block 22a and the second protection block 22b are the same as the pivot center line of the backrest wing 10, so as to simplify the structure in which the backrest wing 10 is respectively pivoted with the first protection block 22a and the second protection block 22 b; the same way to achieve the pivot centre lines of the first and second guard blocks 22a, 22b is: the backrest wing 10 is provided with a pivot shaft 24, preferably, the pivot shaft 24 is arranged along the up-down direction of the backrest wing 10, the first protection block 22a has a first pivot part 221, the second protection block 22b has a second pivot part 222, the pivot shaft 24 passes through the first pivot part 221 and the second pivot part 222, so that the first protection block 22a and the second protection block 22b swing around the pivot shaft 24; of course, the second pivot portion 222 can be formed at the first protection block 22a and the first pivot portion 221 can be formed at the second protection block 22b according to actual requirements, so the invention is not limited thereto. For example, as shown in fig. 8, in the present embodiment, the first pivoting portions 221 are respectively disposed along the axial direction of the pivot shaft 24 in a spaced manner to enclose an engagement space 223, and the second pivoting portion 222 is engaged in the engagement space 223, so that the first protection block 22a and the second protection block 22b which are coaxially pivoted are made more compact in structure and occupy less space; of course, in other embodiments, the second pivoting portions 222 may be respectively disposed in a spaced manner along the axial direction of the pivot shaft 24 to form the engagement space 223, and correspondingly, the first pivoting portion 221 is embedded in the engagement space 223, which is not limited by this example.
As shown in fig. 5, 7 and 8, the end of the energy absorbing mechanism 21 facing the inner wall 224 has an inclined pushed portion 211, and the inclined pushed portion 211 is inclined toward the direction close to the pivot center line L in the opposite direction of the side impact, so that the inner wall 224 more smoothly and reliably forces the energy absorbing mechanism 21 to perform the retracting sliding movement; for example, as shown in fig. 7, the inclined pushed portion 211 is an arc-shaped inclined structure, and correspondingly, the profile of the inner wall 224 matches with the arc-shaped inclined structure, so as to further improve the smoothness and reliability of the energy absorption mechanism 21 forced by the inner wall 224 to perform retraction sliding, which is not limited to this example.
As shown in fig. 5 to 9, the second protection block 22b has an anti-falling structure 225, and the anti-falling structure 225 resists against the backrest side wings 10 when the first protection block 22a is switched from the retracted position to the extended position, so as to prevent the first protection block 22a from falling off from the backrest side wings 10; meanwhile, when the first protection block 22a is located at the unfolding position, the energy absorption mechanism 21 protrudes out of the surface 11 of the backrest wing 10 and blocks the first protection block 22a from being switched to the folding position, so that the first protection block 22a at this time keeps the unfolding position under the action of the anti-falling structure 225 and the energy absorption mechanism 21; for example, in the present embodiment, the anti-separation structure 225 protrudes outward from the outer contour of the first protection block 22a, and is formed by the lip of the first protection block 22 a.
The working principle of the multi-stage side impact protection device is explained with the accompanying drawings: during a side impact of the primary side impact stroke, the side impact force drives the second protective block 22b to have a tendency to fold relative to the first protective block 22 a; when the side impact force enables the inner wall 224 of the second protection block 22b to overcome the resistance of the elastic member 23 to the elastic force of the energy absorption mechanism 21, the inner wall 224 of the second protection block 22b pushes the energy absorption mechanism 21 to slide in the direction allowing the second protection block 22b to be folded relative to the first protection block 22a, and meanwhile, the second protection block 22b is also folded relative to the first protection block 22a, so that the side impact buffering function is realized under the matching of the elastic member 23 and the energy absorption mechanism 21; when the second protection block 22b is folded in place relative to the first protection block 22a, the energy absorption mechanism 21 keeps an interference state with the inner wall 224 of the second protection block 22b under the action of the elastic member 23, so that the first protection block 22a and the second protection block 22b form a secondary side impact stroke; therefore, in the process of side impact in the secondary side impact stroke, the first protection block 22a is switched from the unfolding position to the folding position, so as to drive the second protection block 22b folded relative to the first protection block 22a to move together, and finally the second protection block 22b is attached to the surface 11 of the backrest side wing 10 to be flush, and the state is shown in fig. 2, so that the multi-stage side impact protection effect is realized. It should be noted that, during a side impact, the energy absorption mechanism 21 may be deformed or damaged due to the compression of the second protection block 22b due to the magnitude of the side impact force.
Since the multistage side impact protection device 20 of the present invention includes the energy absorbing mechanism 21 and the force receiving mechanism 22, the force receiving mechanism 22 includes at least two protection blocks that can be selectively folded or unfolded with respect to each other, the force receiving mechanism 22 has an extended position and a retracted position with respect to the backrest side wings 10, the energy absorbing mechanism 21 is movably disposed on one of the two adjacent protection blocks, the energy absorbing mechanism 21 selectively allows or blocks the mutual folding between the two adjacent protection blocks, when the force receiving mechanism 22 is located at the extended position, the force receiving mechanism 22 protrudes out of the surface 11 of the backrest side wings 10, and since the two adjacent protection blocks in the force receiving mechanism 22 can be selectively folded or unfolded with respect to each other, the force receiving mechanism 22 at the extended position obtains multistage side impact stroke by the mutual folding or unfolding combination between the two adjacent protection blocks, so that it is more resistant to side impact, and thus better provides side impact protection, thereby ensuring the safety of the baby; meanwhile, since the two adjacent protection blocks in the stress mechanism 22 can be selectively folded or unfolded, when the stress mechanism 22 is located at the folding position, the size of the stress mechanism 22 at the folding position is reduced by folding the two adjacent protection blocks, so that the stress mechanism 22 located at the folding position is reliably contained in the back wing 10, and the defects that the stress mechanism 22 needs to be thickened when being made into a whole and increasing the safety, and the back wing 10 cannot be contained due to thickening are avoided.
It should be noted that the two protection blocks on the same side of the backrest 10 are illustrated as two, so that the first protection block 22a is the innermost one, and the second protection block 22b is the outermost one; of course, in other embodiments, the number of the protection blocks at the same side of the backrest 10 may also be three, four, five or six, and two adjacent protection blocks are defined as the inner side and the outer side in sequence along the opposite direction of the side impact. Meanwhile, in other embodiments, the elastic member 23 may be omitted, so the invention is not limited thereto.
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 present invention, therefore, the present invention is not limited by the appended claims.
