Wherein, the force-bearing mechanism 310 is symmetrically pivoted to the back-side wing 200, the force-bearing mechanism 310 can pivot relative to the back-side wing 200, and when the force-bearing mechanism 310 pivots to the ejection position relative to the back-side wing 200, the force-bearing mechanism 310 can provide side-impact protection during the use of the child safety seat 100; the force bearing mechanism 310 can save space when pivoted to the stowed position relative to the back-side wing 200. It will be appreciated that the force bearing mechanism 310 has a constant tendency to pivot to an ejected state, and may be implemented specifically by a torsion spring 313 disposed at the pivot of the force bearing mechanism 310 and the back side wing 200 as shown in fig. 3. The limiting mechanism 320 corresponds to the force bearing mechanism 310 and is disposed in the backrest wing 200, and the setting of the limiting mechanism 320 is used for limiting the force bearing mechanism 310 pivoted to the folded state. The automatic control portion 330 is disposed at a position where the child safety seat 100 is convenient to control, and the limiting mechanism 320 does not limit the force-bearing mechanism 310 via the automatic control portion 300 when the child safety seat 100 is in use, so that the force-bearing mechanism 310 is in an ejecting position during use of the child safety seat 100.
It can be appreciated that the automatic control portion 330 may keep the force applied to the child safety seat 100 and the driving limiting mechanism 320 keeps the state of keeping away from the limiting action on the force bearing mechanism 310 during the use of the child safety seat 100, or may be triggered by the force applied to the child safety seat 100 due to the necessary state change of the automatic control portion 330, and the driving limiting mechanism 320 keeps away from the limiting action on the force bearing mechanism 310, where the force bearing mechanism 310 depends on the torsion spring 313 or other structures as shown in fig. 3, so that the force bearing mechanism 310 has a motion trend of keeping constantly in the ejecting position. In this embodiment, as shown in fig. 1, the automatic control portion 330 includes a control member 331 disposed at a sitting position of the child safety seat 100, and may be disposed at a seat portion of the child safety seat 100, when an infant sits on the child safety seat 100, the control member 331 is driven by the infant's own weight, and when the child safety seat 100 is used, the control member 331 is forced to be triggered and drives the driving member 322, so that the limiting mechanism 320 is separated from the limiting effect on the force-bearing mechanism 310, and the control member 331 is constantly subjected to a pressing force in the process of the infant sitting on the child safety seat 100, so that the limiting mechanism 320 is controlled to keep a state of separating from the limiting effect on the force-bearing mechanism 310, and the infant sitting in the child safety seat 100 is in a side collision protection, thereby improving the sitting safety. Of course, the control member 331 may be disposed at a backrest portion, a headrest portion, etc., so long as the control member 331 is forced to be triggered and the driving limiting mechanism 320 is separated from the limiting action on the force-bearing mechanism 310 when the child safety seat 100 is used.
As shown in fig. 1-3, the force-bearing mechanism 310 is disposed substantially transversely in the ejecting state, and the rear end of the force-bearing mechanism 310 near the backrest is pivotally connected to the backrest side wing 200 of the child safety seat 100, and the front end of the force-bearing mechanism 310 far from the backrest can pivot relative to the pivot axis. As shown in fig. 3 and 4, a torsion spring 313 is provided at the pivot axis of the force-bearing mechanism 310 and the back-side wing 200, and the torsion spring 313 makes the force-bearing mechanism 310 constantly have a motion tendency to pivot to the pop-up state. Referring to fig. 5-7, the force-bearing mechanism 310 includes a side-impact protection block 311 and a locking structure 312 pivotally connected to the side-impact protection block 311, where the locking structure 312 is disposed on the outer side of the side-impact protection block 311 in the ejection direction, and the side-impact protection block 311 is provided with an avoidance hole 311a through which the locking structure 312 extends into the inner side of the side-impact protection block 311 in the ejection direction and is limited by the limiting member 321. In this embodiment, as shown in fig. 5 to 7, the engaging structure 312 includes an engaging block 312a disposed on the outer side of the side impact protection block 311 in the ejecting direction, and one end of the engaging block 312a is slidingly connected to the side impact protection block 311; the side-impact protection block 311 is provided with an avoidance hole 311a, a screw 312b passes through the avoidance hole 311a and is fixedly connected to the clamping block 312a, and a nut at one end of the screw 312b away from the clamping block 312a is used for being detachably connected with the limiting mechanism 320, so as to limit the force bearing mechanism 310.
Referring to fig. 4-7, the limiting mechanism 320 includes a limiting member 321, a driving member 322, and a pushing member 323. In this embodiment, the limiting member 321 and the driving member 322 are respectively pivoted to different positions of the backrest wing 200. One end side of the driving piece 322 is pivoted to the backrest wing 200, and the other end side of the driving piece 322 can pivot to drive the limiting piece 321; the driving end of the automatic control portion 330, such as the linking member 332 shown in fig. 5-7, is connected to one side of the driving member 322 and is located at a position substantially in the middle of the driving member 322, so as to drive the driving member 322 to pivot relative to the backrest wing 200. The limiting piece 321 is arranged at the outer side of the free end of the driving piece 322, and the main body part of the limiting piece 321 is circular and pivoted on the back side wing 200 through the circle center of the circular shape of the limiting piece 321; the side of the limiting piece 321, which faces the force bearing mechanism 310, is provided with a clamping hook portion 321a for clamping the force bearing mechanism 310, when the force bearing mechanism 310 rotates to the folding position, the screw 312b is close to the clamping hook portion 321a, and the clamping hook portion 321a is clamped to a nut of the screw 312b to limit the force bearing mechanism 310 to be in a limiting state.
Further, referring to fig. 4 to 7, the pushing member 323 is inserted into the driving member 322; one end of the pushing piece 323 extends out of the driving piece 322 and abuts against the limiting piece 321, the pushing piece 323 protrudes towards one end of the limiting piece 321 to form a pushing portion 323a, and the pushing portion 323a drives the limiting piece 321 to pivot in a direction of separating from the bearing mechanism 310 under the driving of the driving piece 322, so that the clamping hook portion 321a of the limiting piece 321 is separated from the screw 312b of the bearing mechanism 310. Furthermore, the limiting member 321 is also provided with a bump corresponding to the pushing portion 323 a.
It can be understood that the limiting member 321, the driving member 322, and the pushing member 323 all have a motion trend of moving toward the clamping force bearing mechanism 310, and the limiting member 321, the driving member 322, and the pushing member 323 only overcome a motion trend thereof and maintain a state of releasing the force bearing mechanism 310 when the automatic control portion 330 drives the driving member 322. The unidirectional movement trend of the limiting member 321, the driving member 322, and the pushing member 323 can be realized through an elastic member. Specifically, torsion springs 321c and 322a may be disposed at the pivot of the limiting element 321 and the driving element 322 and the back-side wing 200, as shown in fig. 4; a clip 323b for pushing the pushing member 323 to move outwards to push the limiting member 321 may also be disposed on the outer side of the pushing member 323, as shown in fig. 5-7.
In the automatic pop-up side impact protection apparatus provided by the present invention, the stopper mechanism 320 is distant from the automatic control portion 330 for driving the stopper mechanism 320. In order to enable the position of the automatic control portion 330 to be flexibly set, the automatic control portion 330 further includes a linkage member 332, and the linkage member 332 may be a rigid wire. When one end of the linkage member 332 is stressed, the stressed force can be quickly transmitted to the limiting mechanism 320, so as to realize linkage of the two.
The use of the child safety seat 100 with the first embodiment of the auto-eject side-impact protection device of the present invention will be described in detail with reference to fig. 1-7:
when no infant takes the child safety seat 100, the control member 331 is not subjected to an external force. At this time, the limiting member 321, the driving member 322, and the pushing member 323 maintain the state that the hook portion 321a can be engaged with the screw 312b under the action of the torsion springs 321c, 322a, and the clamp spring 323b, and at this time, the force bearing mechanism 310 is at the retracted position, as shown in fig. 1-3;
when an infant sits on the child safety seat 100, the control member 331 is driven by the weight of the infant, the control member 331 is constantly subjected to a pressing force and drives the driving member 322, so that the limiting member 321, the driving member 322 and the pushing member 323 overcome the elastic force of the torsion springs 321c, 322a and the clamp spring 323b, the limiting member 321 is pivoted to a state that the clamping hook portion 321a can not be clamped with the screw 312b, and the force bearing mechanism 310 is pivoted to an ejecting position relative to the back side wing 200 under the elastic force of the torsion spring 313;
it can be understood that, even if the force-bearing mechanism 310 in the ejecting position drives the force-bearing mechanism 310 to overcome the elastic force of the torsion spring 313 under the action of an external force, the control member 331 is pivoted to the folding position, and at this time, the control member 331 is always in a stressed state, so that the limiting member 321, the driving member 322 and the pushing member 323 are in a state of not being able to be clamped with the screw 312 b; however, if the control member 331 is not pressed, the limiting member 321, the driving member 322, and the pushing member 323 operate under the elastic force of the torsion springs 321c, 322a, and the clamp spring 323b, and the hook portion 321a is engaged with the screw 312b to make the bearing mechanism 310 at the retracted position.
In the present embodiment, the force-bearing mechanism 310 is pivoted to the back-side wing 200 and pivots relative to the back-side wing 200 to have an ejecting position and a folding position, and the force-bearing mechanism 310 has a constant motion trend of pivoting to the ejecting position, and the limiting member 321 is engaged with the force-bearing mechanism 310 to keep the force-bearing mechanism 310 in the folding position, and the driving member 322 drives the limiting member 321 such that the force-bearing mechanism 310 pivots to the ejecting position relative to the back-side wing 200 when the limiting member 321 is disengaged from the force-bearing mechanism 310. According to the automatic pop-up side impact protection device provided by the invention, in the use state of the child safety seat 100, the force-bearing mechanism 310 is not limited by the limiting mechanism 320 and automatically pivots to the pop-up position, and in the state that the force-bearing mechanism 310 can be limited under the action of the torsion springs 321c and 322a and the clamp springs 323b when the child safety seat 100 is not used, the force-bearing mechanism 310 is driven to pivot to the folding position by external force, and the force-bearing mechanism 310 is limited by the limiting mechanism 320 so that the force-bearing mechanism 310 can be kept at the folding position. The automatic side-impact protection device provided by the invention can automatically pop up simultaneously to provide enough anti-collision protection for the back-rest side wings in the use process of the child safety seat 100, namely, operation steps are saved and the situation that a child carer forgets to rotate the side-impact protection block to an ejected state is avoided, and the force bearing mechanism 310 can be conveniently pushed to pivot relative to the back-rest side wings 200 and be limited in a folding position by the limiting mechanism 320 in the non-use state of the child safety seat 100, so that the folding volume is reduced.
Fig. 8-10 illustrate another alternative embodiment of a force bearing mechanism 310:
as in the first embodiment of the automatic pop-up side impact protection device shown in fig. 1-7, the back side wing 200 is provided with an arc-shaped limiting block 340 centered on the pivot axis 350 of the force-bearing mechanism 310, the outer edge side of the arc-shaped limiting block 340 is provided with a limiting slot 341, the force-bearing mechanism 310 pivots relative to the pivot axis 350 of the back side wing 200, and the force-bearing mechanism 310 includes a locking structure 312 capable of moving along a direction perpendicular to the pivot axis 350; when the bearing mechanism 310 pivots to the ejecting position relative to the back side wing 200, the engaging structure 312 moves along the direction perpendicular to the pivot axis 350 and engages in the limiting slot 341, so as to limit the bearing mechanism 310 to maintain the ejecting position.
In the present embodiment, further, a limiting surface 342 is further disposed on the outer edge side of the circular arc-shaped limiting block 340, and the limiting surface 342 is correspondingly disposed between the ejecting position and the folding position of the force bearing mechanism 310; the limiting surface 342 is used for limiting the force bearing mechanism 310 pivoted to the ejecting position, so that the force bearing mechanism 310 keeps the semi-open state until the force bearing mechanism 310 is driven by the external force to continue to pivot to the ejecting position.
Fig. 11-13 illustrate yet another alternative embodiment of a force bearing mechanism 310:
As in the first embodiment of the automatic pop-up side impact protection device shown in fig. 1-7, the back side wing 200 is provided with an arc-shaped limiting block 340 centered on the pivot axis of the force-bearing mechanism 310, the outer edge side of the arc-shaped limiting block 340 is provided with a limiting slot 341, the force-bearing mechanism 310 pivots relative to the pivot axis of the back side wing 200, and the force-bearing mechanism 310 includes a locking structure 312 capable of moving along a direction perpendicular to the pivot axis; when the bearing mechanism 310 pivots to the ejecting position relative to the back side wing 200, the engaging structure 312 moves along the direction perpendicular to the pivot axis and engages in the limiting slot 341, so as to limit the bearing mechanism 310 to maintain the ejecting position.
In this embodiment, a tension spring 312c is further disposed between the locking structure 312 and the side-impact protection block 311, and the tension spring 312c makes the locking structure 312 have a constant motion trend of moving toward the arc-shaped limiting block 340 along the direction perpendicular to the pivot axis, so that when the locking structure 312 pivots with the force bearing mechanism 310 to be opposite to the limiting slot 341, the locking structure 312 is locked into the limiting slot 341 under the driving of the tension spring 312 c.
Referring now to fig. 14-16, another alternative embodiment of the automatic control portion 330 of the first embodiment of the automatic pop-up side impact protection apparatus is shown.
In the present embodiment, the automatic control portion 330 includes a control member 331, a linkage member 332, and a reset member 333. The control element 331 is slidably disposed on the backrest portion 110 of the child safety seat 100 and connected to one end of the linking element 332, and the control element 331 partially protrudes from the front surface of the backrest portion 110, the reset element 333 abuts between the control element 331 and the backrest portion 110, and the reset element 333 has a constant tendency to make the control element 331 protrude from the backrest portion 110. Thus, when a child sits in the child safety seat 100, the back of the child will rest against the control member 331 to apply a pressing force to slide the child toward the inside of the backrest 110 (see fig. 16), thereby pulling the link 332, and then pulling the stopper mechanism 320 by the link 332 to release the lock. And, in the process that the control member 331 slides and retracts into the back rest portion 110, the reset member 333 is compressed to generate deformation, and when the control member 331 loses the pressing force, the reset member 333 recovers the deformation to drive the control member 331 to protrude out of the back rest portion 110 (see fig. 15).
It should be understood that the automatic control portion 330 is not limited to the above arrangement, but may be provided at other locations of the child safety seat 100, and fig. 17-18 illustrate yet another alternative embodiment of the automatic control portion 330.
As shown in fig. 14 and 17-18, in this embodiment, the automatic control portion 330 also includes a control member 331, an interlocking member 332, and a resetting member 333, which are different from the above embodiments in that: the control member 331 is slidably disposed in the seat portion 120 of the child safety seat 100 and cooperates with the five-way seat belt 130 disposed on the child safety seat 100, and the control member 331 is driven to move by the adjustment of the five-way seat belt 130 because the five-way seat belt 130 is necessarily pulled to adjust when in use.
More specifically, the control member 331 is disposed at the front end of the seat portion 120 and above the webbing 131a of the reverse locking buckle 131, and the control member 331 is fixedly connected to one end of the traction member 332, and at the same time, the reset member 333 abuts between the control member 331 and the inner wall of the seat portion 120. In use, by pulling the reverse locking buckle 131 to drive the webbing 131a connected with the reverse locking buckle to move, the webbing 131a can apply a force to the control member 331 to enable the control member 331 to slide, so that the traction member 332 is pulled to further pull the limiting mechanism 320 to release the lock. In this process, the restoring member 333 is compressed to generate deformation, and the restoring member 333 can drive the control member 331 to restore the deformation.
It will be appreciated that the control member 331 is not limited to the manner of engaging the webbing 131a of the reverse locking buckle 131 in the present embodiment, but may be provided at other portions of the child safety seat 100 to engage other portions of the five-way seat belt 130, as well as not affecting the implementation of the present solution.
As shown in fig. 19-26, a second embodiment of the auto-eject side impact protection apparatus of the present invention is shown.
In the second embodiment of the automatic pop-up side impact protection apparatus of the present invention, the same automatic pop-up side impact protection apparatus 300' includes a force bearing mechanism 310', a stopper mechanism 320', and an automatic control portion, as in the first embodiment. While the functions of the respective components and the functions to be achieved thereof are the same as those of the first embodiment, but the specific structures thereof are different. Specific:
as shown in fig. 20 to 22, in the second embodiment of the automatic pop-up side impact protection apparatus of the present invention, the automatic control portion includes a control member 331 'provided at the bottom of the child safety seat 100, and an interlocking member 332' having both ends connected to the control member 331 'and the stopper mechanism 320', respectively. The control element 331' is arranged protruding from the bottom of the child safety seat 100, and when the child safety seat 100 is connected to the base 400, the control element 331' protruding from the bottom of the child safety seat 100 is constantly pressed by the base 400, so that the driving element 322' is driven by the linkage element 332', so that the force bearing mechanism 310' automatically pops up, the infant sitting in the child safety seat 100 is ensured to be not hurt, and the sitting safety is improved. Specifically, the control member 331 'is pivotally connected to the bottom of the child safety seat 100 via a pivot 331a', and a driving surface 331b 'is disposed on a side of the control member 331' extending out of the bottom of the seat 100, when the child safety seat 100 is connected to the base 400, the base 400 is pivoted relative to the child safety seat 100 via the driving surface 331b 'to press the control member 331', so as to drive the driving member 322 'via the linking member 332'.
As for the stopper mechanism 320', as shown in fig. 23 to 26: the limiting piece 321' is movably arranged at the outer side of one end of the bearing mechanism 310' away from the pivot joint, limiting surfaces 321a ' and 311a ' are respectively and correspondingly arranged at one sides of the limiting piece 321' and the bearing mechanism 310' opposite to each other, the limiting piece 321' constantly has a motion trend of moving towards the bearing mechanism 310' to limit the bearing mechanism 310' to be at the folding position through the limiting surfaces 321a ' and 311a ', and the driving piece 322' drives the limiting piece 321' to move towards the direction away from the bearing mechanism 310' to release the limit of the bearing mechanism 310 '.
Specifically, in the present embodiment, as shown in fig. 23-26, the lower end side of the force-bearing mechanism 310 'is pivoted to the back-side wing 200, and the upper side of the force-bearing mechanism 310' can pivot to an ejecting position or a folding position relative to the back-side wing 200 with the lower end side as the center; the limiting piece 321 'is arranged on the upper side of the force bearing mechanism 310' and positioned on the outer side of one end of the force bearing mechanism 310 'away from the pivot joint, and the limiting mechanism 320' can move up and down relative to the force bearing mechanism 310 'so as to be close to or far away from the force bearing mechanism 310'; the opposite sides of the limiting piece 321 'and the bearing mechanism 310' are correspondingly provided with limiting surfaces, when the limiting mechanism 320 'moves downwards to be close to the bearing mechanism 310', the bearing mechanism 310 'is limited to keep the folded position through the limiting surfaces, and when the limiting mechanism 320' moves upwards to be far away from the bearing mechanism 310', the bearing mechanism 310' can automatically pivot to the pop-up position under the limitation of the limiting surfaces. It will be appreciated that the stop 321' should always have a tendency to move downward closer to the force bearing mechanism 310', limiting the movement of the force bearing mechanism 310' in the stowed position.
Preferably, as shown in fig. 24-26, the limiting surfaces 321a ', 311a' are inclined from the position near the back side wing 200 to the direction far away from the back side wing 200, that is, the highest point of the inclined surface is near the back side wing 200, and the downward pressing force of the limiting member 321 'generates a component force limiting the ejection of the force-bearing mechanism 310' via the inclined surface.
Referring to fig. 24-26, the driving member 322 'is pivotally connected to the back-rest wing 200' and located at the opposite inner side of the ejecting direction of the force-bearing mechanism 310', and the pivot connection between the driving member 322' and the back-rest wing 200 'is located at the middle position of the driving member 322'; one end side of the driving piece 322 'far away from the bearing mechanism 310' is connected with a driving end of the automatic control part 330', namely one end of the linkage piece 332' as shown in fig. 24-26, the limiting piece 321 'is fixedly connected with a locking pin 321b', the other end side of the driving piece 322 'near the bearing mechanism 310' is provided with a locking groove 322b 'corresponding to the locking pin 321b', and the driving piece 322 'drives the limiting piece 321' to move in a direction far away from the bearing mechanism 310 'through the locking groove 322b' and the locking pin 321b 'under the driving of the linkage piece 332'. It will be appreciated that the driving member 322' has a constant motion tendency to drive the limiting member 321' in the direction of the force bearing mechanism 310 '.
In a second embodiment of the auto-eject side impact protection apparatus of the present invention, the child safety seat 100 is mounted to the base 400 such that the restraining mechanism 320 'releases the force bearing mechanism 310'. The retention mechanism 320' remains engageable with the force bearing mechanism 310' when the child safety seat 100' is removed from the base 400 or not with the base 400.
Referring to fig. 27-33, a third embodiment of the auto-eject side impact protection apparatus of the present invention will be described in detail.
In the third embodiment of the auto-eject side-impact protection apparatus of the present invention, the same as the first embodiment and the second embodiment, the auto-eject side-impact protection apparatus 300 "also includes a force-bearing mechanism 310", a limiting mechanism 320 "and an auto-control portion 330", and the structure of the auto-control portion 330 "is preferably the same as that of the second embodiment, and the details are not repeated, but the functions of other components and the functions to be implemented are the same as those of the first embodiment, but the specific structures thereof are different. Specific:
in this embodiment, the limiting mechanism 320″ is pivotally connected to the back side wing 200, and the limiting mechanism 320″ has an arc-shaped structure centered on the back side wing 200; the bearing mechanism 310 "is pivoted to the back side wing 200, and the bearing mechanism 310" and the limiting mechanism 320 "are pivoted to the same pivot axis of the back side wing 200. The force bearing mechanism 310 "includes a locking structure 315" that can move in a direction perpendicular to the pivot axis of the limiting mechanism 320 "and the back-side wing 200; the circular arc-shaped outer edge side of the limiting mechanism 320 "is provided with a first limiting bit 324" for limiting the clamping structure 315 "so as to keep the bearing mechanism 310" at the closing position, and a second limiting bit 325 "for limiting the clamping structure 316" so as to keep the bearing mechanism 310 "at the opening position; the automatic control portion drives the limiting mechanism 320 "to pivot so that the engagement structure is switched between the first limiting position 324" and the second limiting position 325 ".
Preferably, the engaging structure 315 "has a constant motion tendency to move toward the pivot axis of the limiting mechanism 320" and the backrest wing 200, and may be specifically implemented by an elastic member 315a "as shown in fig. 30-33. As shown in fig. 31-33, at least a portion of the engagement structure 315 "exposes the force bearing mechanism 310" so that an external force operates the engagement structure 315". Further, as shown in fig. 31-33, the limiting mechanism 320' further includes a limiting guide surface 326 "between the first limiting position 324" and the second limiting position 325", and the first limiting position 324" is further away from the pivot axis of the limiting mechanism 320 "and the backrest wing 200 than the second limiting position 325", so that the engaging structure 315 "is easier to separate from the first limiting position 324" and reach the second limiting position 325 "via the limiting guide surface 326" than the engaging structure 315 "limited by the second limiting position 325" is not easy to separate.
Referring to fig. 29-33 in combination, the end of the snap feature 315 "for mating with the first defined bit 324" or the second defined bit 325 "includes a straight face 3152 and a beveled face 3151.
