Description

[Technical Field]

[0001] The present invention relates to a child safety seat base, and more particularly to a side impact protection linkage applied to a safety seat base and a safety seat base. [Background technology]

[0002] A child safety seat is a device that is installed on a car seat and restrains a child on the device through a restraint device. In the event of emergency braking or an accidental collision of the car, the safety seat reduces the injury of the child through the safety seat casing and restrains the child's body movement through the restraint device, so as to reduce the injury of the child in the event of an accident and ensure the safety of the child in the car.

[0003] A child safety seat includes a base and a seat body removably disposed on the base. To provide side impact protection, lateral protection devices are usually disposed on the sides of the seat body of the child safety seat, and the lateral protection devices have a foldable structure. That is, the lateral protection devices need to be manually opened to provide protection when a child is seated in the seat, and the lateral protection devices need to be folded to avoid occupying lateral space when the child leaves the seat. However, when the child safety seat is in use, users often neglect to manually open the lateral protection devices, resulting in the lateral protection devices being unable to function fully.

[0004] Currently, some lateral protection devices can be opened automatically. However, the structure of the drive mechanism for driving the lateral protection device is more complicated, and its response is not very sensitive. Therefore, it is necessary to improve the drive mechanism of the lateral protection device. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION The present invention aims to provide a side impact protection linkage that has a simple structure and a responsive response.

[0006] It is a further object of the present invention to provide a safety seat base with a side impact protection linkage that has a simple construction and a responsive response. [Means for solving the problem]

[0007] This is achieved by a side impact protection linkage according to claim 1 and a safety seat base according to claim 16. The dependent claims relate to corresponding further developments and improvements.

[0008] As will become clearer from the following detailed description, the claimed side impact protection linkage is applied to a safety seat base. The side impact protection linkage includes a side impact protection block pivotally connected to a side wall of the safety seat base, the side impact protection block having a folded position attached to the side wall and an extended position away from the side wall. The side impact protection block has a tendency to rotate to the extended position. A support frame is disposed within the side wall. The support frame includes an engagement member and a link member. An end of the engagement member is pivotally connected to the support frame, and another end of the engagement member has a locking portion slidably protruding from the side wall. The engagement member is releasably engaged with the side impact protection block via the locking portion, thereby locking and unlocking the side impact protection block in the folded position. The link member is disposed below the engagement member and can slide up and down along the support frame. The link member is configured to drive the engagement member to rotate downward, thereby disengaging the locking portion from the side impact protection block. Additionally, the side impact protection linkage further includes a drive member disposed on the safety seat base and connected to the link member.

[0009] Compared with the prior art, the side impact protection link mechanism of the present invention disposes a support frame within the side wall of the safety seat base, and installs an engagement member and a link member on the support frame, with the engagement member being near the side impact protection block and the link member being located below the engagement member. When the link member moves downward along the support frame, the engagement member is driven to rotate downward, thereby separating the locking portion of the engagement member from the side impact protection block and unlocking the engagement member from the side impact protection block. The side impact protection block then extends out of the safety seat base and enters an operative state. Accordingly, by using a support frame to connect the engagement member and the link member with the above-mentioned structure, the present invention has the advantages of a simple structure and a quick response. Moreover, the safety seat base further includes a drive member connected to the link member. When the safety seat base is in use, the drive member is forced to drive the link member downward, thereby automatically starting the operation of the engagement member. As a result, the operation of the present invention is easy to use.

[0010] Preferably, the link member has a hook portion extending toward the engagement member, and the engagement member has a blade fitted to the hook portion, and when the link member moves downward, the hook portion cooperates with the blade to drive the engagement member to rotate downward.

[0016] Preferably, the pivot socket has a positioning member that can slide into and out of the pivot socket, and the side wall of the safety seat base has a positioning hole that corresponds to the positioning member. When the side impact protection block rotates toward the deployed position, the positioning member enters the positioning hole to lock the side impact protection block in the deployed position.

[0017] Preferably, the pivot socket further has an engagement hole adapted to fit over the locking portion of the engagement member, so that when the side impact protection block is rotated to the folded position, the locking portion cooperates with the engagement hole to secure the side impact protection block in the folded position.

[0018] Preferably, the side impact protection block further includes an unlocking member connected to the positioning member, the unlocking member operable to remove the positioning member from the positioning hole.

[0019] Preferably, the unlocking member includes a first link rod and a second link rod. The first link rod has a first pivot portion, a second pivot portion, and a third pivot portion, the first pivot portion and the second pivot portion being disposed at opposite ends of the first link rod, and the third pivot portion being disposed between the first pivot portion and the second pivot portion. The first link rod is pivotally connected to the positioning member by the first pivot portion. The first link rod is pivotally connected to the second link rod by the second pivot portion.

[0021] Preferably, a second resilient member is disposed within the hollow chamber, the second resilient member providing a resilient force to drive the positioning member to automatically extend out of the pivot socket.

[0022] Preferably, an end of the drive member is pivotally connected to the safety seat base, another end of the drive member has a protruding portion that protrudes from the safety seat base, and the pulling member is connected to the end of the drive member where the protruding portion is located.

[0023] Preferably, a resilient member is disposed between the drive member and the safety seat base and is configured to automatically return the drive member.

[0024] As will become more apparent from the detailed description that follows, the claimed safety seat base includes the above-described side impact protection linkage.

[0027] The present invention will be further described in conjunction with the following embodiments and drawings to explain the present disclosure, structural features, principles, and achieved effects in detail.

[0028] As shown in FIGS. 1 to 7 , the present invention provides a safety seat base 200. Two side impact protection linkages 100 are respectively installed on the two side walls 20 of the safety seat base 200. The side impact protection linkages 100 include side impact protection blocks 10. The side impact protection blocks 10 are pivotally connected to the side walls 20 of the safety seat base 200 and have a folded position attached to the side walls 20 (shown in FIGS. 1 and 2 ) and an extended position away from the side walls 20 (shown in FIG. 3 ). The side impact protection blocks 10 have the ability to rotate to the extended position. When the safety seat base 200 is used with the seat main body 300, the side impact protection blocks 10 on both sides automatically deploy to protect a person on the safety seat base 200 from a direct impact. In this embodiment, to simplify the drive mechanism of the side impact protection linkage 100 and increase its responsiveness, the side impact protection linkage 100 further includes a support frame 11 disposed within the side wall 20 of the safety seat base 200. The support frame 11 includes an engagement member 12 and a link member 13 disposed below the engagement member 12. One end of the engagement member 12 is pivotally connected to the support frame 11, and the other end of the engagement member 12 has a locking portion 120 that slidably protrudes from the side wall 20. The engagement member 12 is removably engaged with the side impact protection block 10 via the locking portion 120, thereby locking and unlocking the side impact protection block 10 in the folded position. The link member 13 slides up and down along the support frame 11 and drives the engagement member 12 to rotate downward, thereby disengaging the locking portion 120 from the side impact protection block 10 and unlocking the side impact protection block 10. Moreover, the side impact protection linkage 100 further includes a drive member 14 disposed on the safety seat base 200 and connected to the link member 13. When the safety seat base 200 is in use, the drive member 14 is pushed to drive the link member 13 to move downward along the support frame 11. The link member 13 drives the engagement member 12 to move downward and rotate downward, whereby the locking portion 120 of the engagement member 12 escapes from the side impact protection block 10. As a result, the side impact protection block 10 rotates from the folded position to the unfolded position.

[0029] As shown in FIG. 14 , one end of the drive member 14 is pivotally connected to the safety seat base 200, another end of the drive member 14 has a protruding portion 140 protruding from the safety seat base 200, and a tension member 17 is connected to the end of the drive member 14 where the protruding portion 140 is disposed. In this embodiment, the tension member 17 is a steel wire. When the safety seat base 200 is in use, the protruding portion 140 is pushed and moves downward, driving the link member 13 to move downward via the steel wire. Moreover, an elastic member 141 may be further disposed between the drive member 14 and the safety seat base 200 and configured to automatically return the drive member 14. The elastic member 141 may be a torsion spring, a tension spring, or the like.

[0030] A preferred connection between the link member 13 and the engagement member 12 is shown in Figures 6 and 7. The link member 13 has a hook portion 130 extending toward the engagement member 12, and the engagement member 12 has a wing 121 fitted to the hook portion 130. In this embodiment, the wing 121 extends from the end of the engagement member 12 near the pivot axis toward the end of the locking portion 120. When the link member 13 moves downward, the hook portion 130 pulls the wing 121 downward, driving the engagement member 12 to rotate downward, thereby disengaging the locking portion 120 from the side impact protection block 10. In addition, the support frame 11 has two bearing holes 111 opposite each other. The pivot axis of the engagement member 12 is pivotally connected to the support frame 11 via the two bearing holes 111. Furthermore, the support frame 11 has two first longitudinal grooves 110 opposite to each other, and the link member 13 has two protruding shafts 131 fitted into the two first longitudinal grooves 110. The link member 13 is slidably connected to the support frame 11 through cooperation between the two protruding shafts 131 and the two first longitudinal grooves 110. When the steel wire is forced to pull the link member 13, the link member 13 moves downward along the first longitudinal grooves 110.

[0031] As shown in FIG. 7 , a first elastic member 16 is disposed between the lower end of the link member 13 and the support frame 11 to automatically return the link member 13. The first elastic member 16 provides an elastic force to drive the engagement member 12 to move upward along the support frame 11. When the link member 13 is pulled and moves downward, the first elastic member 16 is compressed and elastically deformed. When the pulling force acting on the link member 13 is no longer present, the elastic force of the first elastic member 16 pushes the link member 13 back to the upper end, thereby automatically returning the link member 13. In addition, a first torsion spring 122 is sleeved on the pivot shaft of the engagement member 12 to give the engagement member 12 the ability to rotate upward and place the side impact protection block 10 in the deployed position. A free end of the first torsion spring 122 abuts the engagement member 12, and another free end of the first torsion spring 122 abuts the support frame 11.

[0032] As shown in FIG. 8 , the side impact protection block 10 is pivotally connected to the side wall 20 of the safety seat base 200 by a pivot socket 101. In this embodiment, the pivot socket 101 is a cylindrical structure formed integrally with the side impact protection block 10. A second torsion spring 102 is sleeved on the pivot axis of the pivot socket 101. The second torsion spring 102 provides a driving force for driving the side impact protection block 10 to rotate toward the deployed position. When the drive member 14 unlocks the engagement member 12 from the side impact protection block 10, the side impact protection block 10 is automatically rotated toward the deployed position by the second torsion spring 102.

[0033] 4, 6, and 8, in order to properly position the side impact protection block 10 when the side impact protection block 10 is in the deployed position, the pivot socket 101 has a positioning member 1010 that can slide in and out of the pivot socket 101. Moreover, the pivot socket 101 has an opening 1012 through which the positioning member 1010 enters and exits. The side wall 20 of the safety seat base 200 has positioning holes 21 that correspond to the positioning member 1010. When the side impact protection block 10 rotates to the deployed position, the positioning member 1010 enters the positioning hole 21 (as shown in FIGS. 11 and 13) to lock the side impact protection block 10 in the deployed position. When the side impact protection block 10 rotates toward the folded position, the positioning member 1010 exits from the positioning hole 21 (as shown in FIGS. 11 and 12). In this embodiment, when the side impact protection block 10 is rotated to the unfolded position, the positioning member 1010 automatically enters the positioning hole 21, whereby the side impact protection block 10 is positioned by cooperation between the positioning member 1010 and the positioning hole 21. Moreover, the pivot socket 101 further has an engagement hole 1011 that is adapted to the lock portion 120 of the engagement member 12. When the side impact protection block 10 is rotated to the folded position, the lock portion 120 automatically enters the engagement hole 1011, whereby the side impact protection block 10 is fixed in the folded position by cooperation between the lock portion 120 and the engagement hole 1011. Preferably, to facilitate fixing and installation of the support frame 11, in this embodiment, the support frame 11 is connected to the side wall 20 of the side impact protection block 10 by an installation frame 15.

[0034] 9 and 10 , to facilitate the folding process of the side impact protection block 10 when the safety seat base 200 is in the idle state, the side impact protection block 10 further includes an unlocking member 103 connected to the positioning member 1010, which operates to remove the positioning member 1010 from the positioning hole 21. Preferably, the unlocking member 103 includes a first link rod 1030 and a second link rod 1031. The first link rod 1030 has a first pivot portion 1032, a second pivot portion 1033, and a third pivot portion 1034, the first pivot portion 1032 and the second pivot portion 1033 being disposed at opposite ends of the first link rod 1030, and the third pivot portion 1034 being disposed between the first pivot portion 1032 and the second pivot portion 1033. The first link rod 1030 is pivotally connected to the positioning member 1010 by a first pivot portion 1032. The first link rod 1030 is pivotally connected to the second link rod 1031 by a second pivot portion 1033. The first link rod 1030 is pivotally connected to the side impact protection block 10 by a third pivot portion 1034. The end of the second link rod 1031 has an operating portion 1035 remote from the first link rod 1030. The operating portion 1035 has a rib 1036 protruding toward the bottom wall of the side impact protection block 10. Via the rib 1036, the angle included between the deployment direction of the first link rod 1030 and the deployment direction of the second link rod 1031 is in a natural state. When the side impact protection block 10 needs to be folded from the unfolded position to the folded position, the operating member 1035 of the second link rod 1031 is pulled in the direction indicated by the arrow F2 in FIG. 9. Then, another end of the second link rod 1031 drives the tip of the second pivot portion 1033 of the first link rod 1030 to bend it downwardly in an arch shape onto the rib 1036, so that the front end of the first link rod 1030 tilts upwardly onto the third pivot portion 1034, driving the positioning member 1010 to be pushed out of the positioning hole 21 and into the pivot socket 101. The unlocking member 103 of this embodiment has the advantages of a simple structure and easy operation.

[0035] To facilitate installation of the unlocking member 103, as shown in FIG. 9 , the side impact protection block 10 includes an outer casing 104 and an inner casing 105 that are screwed together. The pivot socket 101 is disposed on the outer casing 104, and the pivot socket 101 has a hollow structure. The outer casing 104 has a storage recess 106 for storing the first link rod 1030 and the second link rod 1031. The storage recess 106 communicates with the hollow chamber within the pivot socket 101. The side wall of the inner casing 105 has a pivot hole 108 for pivotally connecting the third pivot portion 1034 of the first link rod 1030. Furthermore, the inner casing 105 has a through hole 107 that communicates with the storage recess 106. The operating portion 1035 of the second link rod 1031 passes through the through-hole 107 of the inner casing 105 and is exposed from the outside of the side impact protection block 10 .

[0036] A specific connection structure between the first link rod 1030 and the positioning member 1010 is preferably as shown in FIG. 10 . A hollow chamber 1016 is formed in the positioning member 1010. The side wall of the positioning member 1010 has a second longitudinal groove 1014 communicating with the hollow chamber 1016. The pivot shaft of the side impact protection block 10 passes through the second longitudinal groove 1014 and the hollow chamber 1016. When the first link rod 1030 drives the positioning member 1010 to tilt upward, the positioning member 1010 moves upward along the pivot shaft of the side impact protection block 10 through the second longitudinal groove 1014. In addition, a second elastic member 1015 may be further disposed in the hollow chamber 1016 of the positioning member 1010. The second elastic member 1015 provides an elastic force to drive the positioning member 1010 to automatically extend out of the pivot socket 101 .

[0037] The operation of the safety seat base with the side impact protection linkage 100 of the present invention will now be described with reference to FIGS.

[0038] When the safety seat base 200 does not need to be used, the side impact protection block 10 is folded into the storage recess 22 on the side wall 20. The locking portion 120 of the engagement member 12 extends out of the side wall 20 to engage into the engagement hole 1011 of the side impact protection block 10, locking the side impact protection block 10 in the folded position. At this point, the positioning member 1010 is compressed by the side wall 20 and stored within the pivot socket 101 of the side impact protection block 10, simultaneously compressing the second elastic member 1015.

[0039] When the seat body 300 is installed on the safety seat base 200, the bottom of the seat body 300 presses the protruding portion 140 disposed on the safety seat base 200, driving the driving member 14 to rotate. The driving member 14 pulls the engaging member 12 via the steel wire and link member 13, causing it to slide in the direction indicated by arrow F1 in FIG. 14 , so that the locking portion 120 of the engaging member 12 is separated from the engaging hole 1011 of the side impact protection block 10. At this point, the side impact protection block 10 is pushed out by the pressing force of the second torsion spring 102 and rotates from the folded position to the unfolded position. Furthermore, the driving member 14 rotates to deform the elastic member 141, and at the same time, the engaging member 12 rotates to deform the first torsion spring 122.

[0040] After the side impact protection block 10 rotates and escapes, the position of the positioning member 1010 of the side impact protection block 10 corresponds to the positioning hole 21 on the side wall 20 of the safety seat base 200. Because the positioning member 1010 is not pressed by the side wall 20, the positioning member 1010 escapes and engages into the engagement hole 21 by the action of the second elastic member 1015, so that the side impact protection block 10 is held in the deployed position by the positioning member 1010.

[0041] When the side impact protection block 10 needs to be folded, the operating portion 1035 of the second link rod 1031 is pulled, pulling the positioning member 1010 out of the positioning hole 21 via the first link rod 1030. When the positioning member 1010 is disengaged from the positioning hole 21, the side impact protection block 10 can be pushed and rotated to the folded position. The seat body 300 is then removed. Because the protruding portion 140 of the drive member 14 is no longer pressed by the seat body 300, the drive member 14 rotates and returns under the action of the elastic member 141. The tension force on the steel wire is no longer present, and the link member 13 returns under the action of the second torsion spring, which in turn returns the engagement member 12 under the action of the first torsion spring 122. As a result, the locking portion 120 of the engagement member 12 enters the engagement hole 1011 of the pivot socket 101 to lock the side impact protection block 10.

[0042] Due to the innovative arrangement of the side impact protection linkage of the present invention, the safety seat base 200 has side impact protection effect, and the linkage for controlling the side impact protection block 10 is optimized, so that the movement of the side impact protection block 10 is more sensitive, and the structure is simple and easy to manufacture.
