Folded position is mutually received between 22b, certainly, there is also the inner walls 224 of the second protection block 22b, and energy absorption mechanism 21 to be forced to generate
Deformation and to side crash energy absorption bumper；When force mechanism 21 (specific first protection block 22a) folds position positioned at as shown in Figure 1
When setting, the first protection block 22a and the second protection block 22b are received folded and are made the second protection block 22b along side crash direction (i.e. arrow A is signified)
With 11 flush of surface for leaning against flank 10 so that safety seat 100 at this time is more attractive.More specifically, as follows:
As shown in Figures 4 and 8, the first protection block 22a and the second protection block 22b respectively with lean against flank 10 and be pivotally connected so that the
One protection block 22a and the second protection block 22b is opposite to lean against 10 pivot of flank pendulum, certainly, makes the first protection block according to actual needs
22a, which is slidedly arranged on, to be leaned against on flank 10, this second protection block 22b is slidedly arranged on the first protection block 22a again, is equally able to achieve the first protection
Folded or expansion is mutually received between block 22a and the second protection block 22b；Specifically, in the present embodiment, the first protection block 22a and
Two protection block 22b are identical as the pivot centerline for leaning against flank 10, with simplify lean against flank 10 respectively with the first protection block 22a and
The structure of second protection block 22b pivot joint；Realize the pivot centerline same way of the first protection block 22a and the second protection block 22b
It is: leans against and pivotal axis 24 is installed on flank 10, be preferably, pivotal axis 24 is arranged along the up and down direction for leaning against flank 10, the
One protection block 22a has first pivoting portion 221, and the second protection block 22b has second pivoting portion 222, and pivotal axis 24 passes through first
Articulated section 221 and second pivoting portion 222, so that the first protection block 22a and the second protection block 22b is put around 24 pivot of pivotal axis；When
So, second pivoting portion 222 can be formed at the first protection block 22a according to actual needs, and first pivoting portion 221 is formed
At the second protection block 22b, therefore it is not limited.For example, as shown in figure 8, in the present embodiment, first pivoting portion 221
It is in the arrangement being separated from each other along the axial direction of pivotal axis 24 respectively and surrounds interlocking space 223, second pivoting portion 222 is embedded at embedding
It connects in space 223, so that the first protection block 22a and the second protection block 22b that are coaxially pivotally connected are made more compact in structure, accounts for
It is smaller with space；It certainly, in other embodiments, can be by second pivoting portion 222 respectively along the axial direction of pivotal axis 24 in each other
The arrangement separated is corresponding to form interlocking space 223, and first pivoting portion 221 is embedded in interlocking space 223, therefore not with this
Citing is limited.
As shown in Fig. 5, Fig. 7 and Fig. 8, energy absorption mechanism 21 has inclination pushed part 211 in face of the end of inner wall 224,
It tilts pushed part 211 and is tilted along side crash opposite direction towards the direction close to pivot centerline L, it can so that inner wall 224 is more smooth
Energy absorption mechanism 21 is forced to do the sliding to bounce back by ground；For example, as shown in fig. 7, inclination pushed part 211 is arc-shaped recliner
Structure, accordingly, profile and the arc oblique structure of inner wall 224 match, and further improve inner wall 224 and force energy absorption
The smoothness and reliability of retraction sliding are done by mechanism 21, therefore are not illustrated and be limited with this.
As shown in Figures 5 to 9, the second protection block 22b has disconnecting prevention structure 225, and disconnecting prevention structure 225 is in the first protection block
When 22a switches to displayed position by stowed position with lean against flank 10 and keep out, to stop the first protection block 22a from leaning against flank
10 fall off；Meanwhile energy absorption mechanism 21 protrudes the surface 11 for leaning against flank 10 when the first protection block 22a is located at displayed position
And the first protection block 22a is stopped to switch to stowed position, so that the first protection block 22a at this time is in disconnecting prevention structure 225 and energy
Displayed position is kept under the action of absorbing mechanism 21；For example, in the present embodiment, disconnecting prevention structure 225 is protruded outward in
At the outer profile of one protection block 22a, formed by the lip of the first protection block 22a.
In conjunction with attached drawing, the working principle of multistage side crash protective device is illustrated: in the side crash mistake of level-one side crash stroke
Cheng Zhong, side crash power drive the second protection block 22b that there is opposite first protection block 22a to receive folded trend；When side crash power makes second
The inner wall 224 of protection block 22b overcomes elastic component 23 to when the keeping out of elastic force of energy absorption mechanism 21, the second protection at this time
The inner wall 224 of block 22b just pushing tow energy absorption mechanism 21 toward allow the second protection block 22b with respect to phase between the first protection block 22a
Folded direction sliding is mutually received, meanwhile, the second protection block 22b is also folded with respect to the first protection block 22a receipts, therefore in elastic component 23 and energy
The pooling feature of side crash is realized under the cooperation of absorbing mechanism 21；When the second protection block 22b is laminated to position with respect to the first protection block 22a receipts
When, energy absorption mechanism 21 at this time keeps contradicting with the inner wall 224 of the second protection block 22b always under the action of elastic component 23
State, so that the first protection block 22a and the second protection block 22b at this time constitutes second level side crash stroke；Therefore in second level side crash
During the side crash of stroke, so that the first protection block 22a switches to stowed position by expanded position, to drive opposite first to protect
The second protection block 22b after protecting block 22a is folded is moved together, is finally made the second protection block 22b and is leaned against the surface of flank 10
11 fittings are concordant, and state as shown in Figure 2, thus realizes multistage side crash protective effect.The person of being worth noting, during side crash, by
In the size relation of side crash power so that energy absorption mechanism 21 exist due to by extruding to the second protection block 22b deformation or by
Damage may.
Since multistage side crash protective device 20 of the invention includes energy absorption mechanism 21 and force mechanism 22, force mechanism
22 include at least two protection blocks that optionally mutual receipts are folded or are mutually unfolded, and force mechanism 22 is opposite to lean against the tool of flank 10
There are displayed position and stowed position, energy absorption mechanism 21 is actively set to one in two adjacent protection blocks, energy absorption mechanism
21 selectively allow for or stop mutually to receive between two adjacent protection blocks to fold, therefore when force mechanism 22 is located at displayed position, by
Force mechanisms 22 protrude from the surface 11 for leaning against flank 10, and due to selecting property ground phase between two adjacent protection blocks in force mechanism 22
Mutually receipts are folded or are mutually unfolded, so that the force mechanism 22 of displayed position is folded or is unfolded by mutually receiving between two adjacent protection blocks
Combination and obtain multistage side crash stroke, therefore more resistant to lateral impact, thus it is more preferable side crash protection is provided, so that it is guaranteed that the peace of baby
Entirely；Meanwhile folded or exhibition just is received due to alternative between two adjacent protection blocks in force mechanism 22, therefore at force mechanism 22
When stowed position, volume of the force mechanism 22 when the stowed position is reduced by receiving folded between two adjacent protection blocks at this time,
So that the force mechanism 22 for being located at stowed position is reliably accommodated in and leans against in flank 10, avoid force mechanism 22 because being made into
It integrally and needs to thicken when increasing safety, and causes to lean against the defect that flank 10 can not be stored because of thickening.
The person of being worth noting, what the above-mentioned protection block for leaning against 10 the same side of flank was illustrated with two, therefore, the first protection
Block 22a is most inner side person, and the second protection block 22b is outermost person；Certainly, in other embodiments, 10 the same side of flank is leaned against
The quantity of protection block can also differ for three, four, five or six, opposite direction of the two adjacent protection blocks along side crash at this time
Successively it is defined as inside person and outside person.Meanwhile in other embodiments, elastic component 23 can be saved, therefore be not limited.
Upper disclosed is merely a preferred embodiment of the present invention, and cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalent variations made by scope of the present invention patent, is still within the scope of the present invention.
