Description

Technical Field

[0001] The present invention relates to the technical field of child seats, and in particular to an ISOFIX assembly for installing a child seat and a method of using the same. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights) and installed in a car to effectively improve the safety of children riding in a car. European regulation ECE R44 / 03 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly with a buckle or flexible components, adjustment mechanisms, accessories, etc. It can be combined with additional devices such as a portable crib, infant carrier, auxiliary seat or collision protection. In the event of a car collision or sudden deceleration, it can reduce the impact force on the child and restrict the child's body movement to reduce their injuries and ensure their safety. Child seats with support leg structures are more stable and safer and can effectively protect children. ISOFIX components are used to install child seats on car seats. The seat is installed by connecting the ISOFIX components to the connecting shaft of the car seat.

[0015] A method for using an ISOFIX component for installing a child seat, including a method for locking and connecting the ISOFIX component and a method for unlocking and disconnecting the ISOFIX component;

[0016] The method for using the ISOFIX component lock connection includes the following steps:

[0017] Step (A1), in the initial stage, the FIX housing is received into the outer frame, the upper protruding end of the second locking member is engaged with the upper locking hole of the outer frame, and the lower protruding end of the first locking member is blocked by the outer frame and received into the FIX housing;

[0018] In step (B1), during the pushing-out stage, the button is pressed, causing the connecting pin of the button to pull the rib rod to move, causing the second sliding shaft of the second locking member to slide along the lower inclined surface of the rib rod, thereby causing the second locking member to rotate, retracting the upper protruding end of the second locking member into the FIX housing. At the same time, the first support spring and the second support spring are in a compressed state. Moreover, when the rib rod moves, the rib rod also drives the stopper to move and pulls the traction spring to extend, finally pushing the FIX housing out of the outer frame.

[0019] In step (C1), during the limiting stage, the button is released, causing the traction spring to contract and pull the rib rod to move. The arc surface on the right side of the locking member contacts the FIX housing. The rib rod carries the stopper to move and abut against the arc surface on the left side of the locking member, restricting the locking member. The first support spring and the second support spring extend, pushing the lower protruding end of the first locking member and the upper protruding end of the second locking member out of the FIX housing, causing the lower protruding end of the first locking member to be inserted into the lower locking hole of the outer frame, and the upper protruding end of the second locking member to be inserted into the upper locking hole of the outer frame again.

[0020] In step (D1), during the locking connection stage, a connecting shaft for installing the child seat is inserted into the interface of the FIX housing. The connecting shaft hits the locking member to cause it to rotate. During the rotation of the locking member, the traction spring is pulled to gradually extend until the block is engaged in the limiting groove of the locking member and the traction spring contracts, locking the connecting shaft in the locking groove of the locking member. When the traction spring contracts, the rib rod is pulled to move, and the first sliding shaft of the first locking member slides along the upper inclined surface of the rib rod, causing the first locking member to rotate, compressing the first support spring, and retracting the lower protruding end of the first locking member into the FIX housing.

[0021] The method for unlocking and disconnecting the ISOFIX component comprises the following steps:

[0022] In step (A2), in the initial stage, the connecting shaft for installing the child seat is locked in the locking groove of the locking member, the stopper is engaged in the limiting groove of the locking member, the lower protruding end of the first locking member is retracted into the FIX housing, the first support spring is in a compressed state, and the upper protruding end of the second locking member is engaged in the upper locking hole of the outer frame;

[0023] In step (B2), during the unlocking and disconnecting phase, the button is pressed, causing the connecting pin of the button to move the rib rod, which in turn drives the stopper to move and pulls the traction spring to extend. When the stopper moves out of the limiting groove of the locking member, the traction spring contracts and pulls the locking member to rotate, causing the locking member to no longer lock the connecting shaft, thereby disconnecting the connecting shaft from the FIX housing.

[0024] Step (C2), the limit release stage, which is carried out simultaneously with the unlocking and disconnecting stage. When the rib bar moves, the first sliding shaft of the first locking member slides along the upper inclined surface of the rib bar, and the state of the lower protruding end of the first locking member changes from being retracted to being extended and then retracted. The second sliding shaft of the second locking member slides along the lower inclined surface of the rib bar, and the upper protruding end of the second locking member is retracted into the interior of the FIX housing, so that the upper protruding end of the second locking member moves out from the interior of the upper locking hole of the outer frame and no longer restricts the sliding of the FIX housing.

[0025] Step (D2), the storage stage, stores the FIX shell into the outer frame, releases the button, causes the traction spring to contract and pulls the rib rod to move, the arc surface on the right side of the locking part contacts the FIX shell, the rib rod carries the block to move and presses against the arc surface on the left side of the locking part, restricting the locking part, the first support spring and the second support spring extend, the lower protruding end of the first locking part is blocked by the outer frame and stored in the FIX shell, the upper protruding end of the second locking part extends out of the FIX shell and is re-engaged in the upper locking hole of the outer frame.

[0026] Compared with the prior art, the present invention is provided with a button, a rib rod, a block, a traction spring and a locking piece. When installing a child seat, the connecting shaft for installing the child seat is inserted into the interface of the FIX shell, so that it hits the locking piece to rotate, and cooperates with the block and the traction spring to lock the connecting shaft into the locking piece. When removing the child seat, the block is moved out of the limiting groove of the locking piece by pressing the button, and then the traction spring pulls the locking piece to rotate and release the lock of the connecting shaft. This structure is simple and easy to connect the ISOFIX component to the connecting shaft, thereby improving the efficiency of disassembly and assembly of the child seat. The present invention is also provided with a first locking piece and a second locking piece. Through the one-piece molding structure of the rib rod and the double-piece symmetrical structure of the first locking piece and the second locking piece, the structural strength inside the ISOFIX component is improved and the stability is improved.

[0048] A method for using an ISOFIX component for installing a child seat, including a method for locking and connecting the ISOFIX component and a method for unlocking and disconnecting the ISOFIX component;

[0049] The method of using the ISOFIX component lock connection includes the following steps:

[0050] Step A1: Initially, the FIX housing 1 is received into the outer frame 19 , the upper protruding end of the second locking member 17 is inserted into the upper locking hole 1901 of the outer frame 19 , and the lower protruding end of the first locking member 15 is blocked by the outer frame 19 and received into the FIX housing 1 ;

[0051] Step B1, in the push-out stage, the button 10 is pressed, so that the connecting pin of the button 10 pulls the rib bar 2 to move, causing the second sliding shaft 1701 of the second locking member 17 to slide along the lower inclined surface 202 of the rib bar 2, thereby causing the second locking member 17 to rotate, and the upper protruding end of the second locking member 17 is retracted into the FIX housing 1. At the same time, the first support spring 16 and the second support spring 18 are in a compressed state. The state of the contents of the FIX housing 1 is as follows: Figure 6As shown, when the rib rod 2 moves, the rib rod 2 also drives the stopper 11 to move and pulls the traction spring 12 to extend, and finally pushes the FIX housing 1 out from the inside of the outer frame 19;

[0052] In step C1, the limiting stage, the button 10 is released to shrink the traction spring 12 and pull the rib rod 2 to move. The arc surface on the right side of the lock member 13 contacts the FIX housing 1. The rib rod 2 carries the stopper 11 to move and press against the arc surface on the left side of the lock member 13 to limit the lock member 13. The first support spring 16 and the second support spring 18 are extended to push the lower protruding end of the first locking member 15 and the upper protruding end of the second locking member 17 out of the FIX housing 1, causing the lower protruding end of the first locking member 15 to be stuck in the lower locking hole 1902 of the outer frame 19, and the upper protruding end of the second locking member 17 to be re-stuck in the upper locking hole 1901 of the outer frame 19. The content status of the FIX housing 1 is as follows: Figure 4 As shown;

[0053] In step D1, during the lock connection stage, the connecting shaft for installing the child seat is inserted into the interface 103 of the FIX housing 1. The connecting shaft hits the lock member 13 to cause it to rotate. During the rotation of the lock member 13, the traction spring 12 is pulled to gradually extend until the stopper 11 is engaged in the limiting groove 1302 of the lock member 13. The internal traction spring 12 contracts, locking the connecting shaft in the lock groove 1301 of the lock member 13. When the traction spring 12 contracts, the rib bar 2 is pulled to move. The first sliding shaft 1501 of the first locking member 15 slides along the upper inclined surface 201 of the rib bar 2, causing the first locking member 15 to rotate and compress the first supporting spring 16, and the lower protruding end of the first locking member 15 is retracted into the interior of the FIX housing 1. The contents of the FIX housing 1 are as shown in FIG. Figure 5 As shown;

[0054] The method for unlocking and disconnecting the ISOFIX component includes the following steps:

[0056] Step B2, unlocking and disconnecting stage, press the button 10, so that the connecting pin of the button 10 drives the rib rod 2 to move, and the rib rod 2 drives the stopper 11 to move and pulls the traction spring 12 to extend. When the stopper 11 moves out of the limiting groove 1302 of the lock member 13, the traction spring 12 contracts and pulls the lock member 13 to rotate, so that the lock member 13 no longer locks the connecting shaft, and the connecting shaft is disconnected from the FIX housing 1. The status of the contents of the FIX housing 1 is as follows: Figure 6 As shown;

[0057] Step C2, limit release stage, this stage is carried out simultaneously with the unlocking and disconnecting stage. When the rib bar 2 moves, the first sliding shaft 1501 of the first locking member 15 slides along the upper inclined surface 201 of the rib bar 2, and the state of the lower protruding end of the first locking member 15 changes from being retracted to being extended and then retracted. The second sliding shaft 1701 of the second locking member 17 slides along the lower inclined surface 202 of the rib bar 2, and the upper protruding end of the second locking member 17 is retracted into the interior of the FIX housing 1, so that the upper protruding end of the second locking member 17 moves out from the upper locking hole 1901 of the outer frame 19 and no longer restricts the sliding of the FIX housing 1;

[0058] In step D2, the storage stage, the FIX housing 1 is stored inside the outer frame 19, and the button 10 is released to contract the traction spring 12 and pull the rib rod 2 to move. The arc surface on the right side of the locking member 13 contacts the FIX housing 1, and the rib rod 2 carries the stopper 11 to move and press against the arc surface on the left side of the locking member 13, restricting the locking member 13. The first support spring 16 and the second support spring 18 are extended, and the lower protruding end of the first locking member 15 is blocked by the outer frame 19 and stored inside the FIX housing 1. The upper protruding end of the second locking member 17 extends out of the FIX housing 1 and is re-engaged in the upper locking hole 1901 of the outer frame 19.

During the rotation of the locking member (13), the traction spring (12) is pulled to gradually extend until the stopper (11) is engaged in the limiting groove (1302) of the locking member (13) and the internal traction spring (12) contracts, locking the connecting shaft in the locking groove (1301) of the locking member (13). When the traction spring (12) contracts, the rib rod (2) is pulled to move, and the first sliding shaft (1501) of the first locking member (15) slides along the upper inclined surface (201) of the rib rod (2), causing the first locking member (15) to rotate and compress the first supporting spring (16), and the lower protruding end of the first locking member (15) is received into the interior of the FIX housing (1); The method for unlocking and disconnecting the ISOFIX component comprises the following steps: Step (A2), initial stage, the connecting shaft for installing the child seat is locked in the locking groove (1301) of the locking member (13), the stopper (11) is engaged in the limiting groove (1302) of the locking member (13), the lower protruding end of the first locking member (15) is received in the FIX housing (1), the first supporting spring (16) is in a compressed state, and the upper protruding end of the second locking member (17) is engaged in the upper locking hole (1901) of the outer frame (19); In step (B2), the unlocking and disconnecting stage, the button (10) is pressed, so that the connecting pin of the button (10) drives the rib rod (2) to move, and the rib rod (2) drives the stopper (11) to move and pulls the traction spring (12) to extend. When the stopper (11) moves out of the limiting groove (1302) of the locking member (13), the traction spring (12) contracts and pulls the locking member (13) to rotate, so that the locking member (13) no longer locks the connecting shaft, and the connecting shaft is disconnected from the FIX housing (1); Step (C2), the limit release stage, which is carried out simultaneously with the unlocking and disconnecting stage. When the rib rod (2) moves, the first sliding shaft (1501) of the first locking member (15) slides along the upper inclined surface (201) of the rib rod (2), and the state of the lower protruding end of the first locking member (15) changes from being retracted to being extended and then being retracted. The second sliding shaft (1701) of the second locking member (17) slides along the lower inclined surface (202) of the rib rod (2), and the upper protruding end of the second locking member (17) is retracted into the interior of the FIX housing (1), so that the upper protruding end of the second locking member (17) moves out from the interior of the upper locking hole (1901) of the outer frame (19) and no longer restricts the sliding of the FIX housing (1); In step (D2), the storage stage, the FIX housing (1) is stored inside the outer frame (19), the button (10) is released, the traction spring (12) contracts and pulls the rib rod (2) to move, the arc surface on the right side of the locking member (13) contacts the FIX housing (1), the rib rod (2) carries the stopper (11) to move and press against the arc surface on the left side of the locking member (13), restricting the locking member (13), the first support spring (16) and the second support spring (18) are extended, the lower protruding end of the first locking member (15) is blocked by the outer frame (19) and stored inside the FIX housing (1), and the upper protruding end of the second locking member (17) extends out of the FIX housing (1) and is re-engaged in the upper locking hole (1901) of the outer frame (19).
