Figure 3 , which is a partial structural schematic view of the child restraint base 11 according to an embodiment of the present invention when the fixing strap 114 is in the storage position. Figure 4 , which is another partial structural schematic view of the child restraint base 11 according to an embodiment of the present invention. Figure 5 , which is a schematic view of the third plate member 115 according to an embodiment of the present invention. As Figures 2 to 5 shown, the child restraint base 11 includes a base body 111, a first plate member 112, a second plate member 113, a fixing strap 114, a third plate member 115, a first fixing hook 116, a second fixing hook 117, a first pocket structure 118, a second pocket structure 119, a first cover 11A and a second cover 11B. The base body 111 is used for mounting the child restraint carrier 12. First channels 1111 and second channels 1112 for the fixing strap 114 or the seat belt of the vehicle to pass through are formed on both side portions of the base body 111. The first plate member 112 is disposed on the base body 111, and a first through slot 1113 is formed between the first plate member 112 and the base body 111. The second plate member 113 is disposed on the base body 111 and is spaced from the first plate member 112, and a second through slot 1114 is formed between the second plate member 113 and the base body 111.

[0056] The fixing strap 114 is threaded through the first through slot 1113 and the second through slot 1114 and can slide along the first through slot 1113 and the second through slot 1114 between the use position and the storage position. The third plate member 115 is disposed between the first plate member 112 and the second plate member 113 and can pivot relative to the base body 111 between an open position and a closed position to eliminate the slack of the fixing strap 114 or the seat belt of the vehicle. The first fixing hook 116 and the second fixing hook 117 are connected to both ends of the fixing strap 114 and are used to connect to the vehicle. The first pocket structure 118 and the second pocket structure 119 are located on the outer edge of the base body 111 and at the two front side portions of the base body 111. The first pocket structure 118 is used to accommodate the first fixing hook 116 when the fixing strap 114 is in the storage position and has a top opening 1181 for convenient use. The second pocket structure 119 is used to accommodate the second fixing hook 117 when the fixing strap 114 is in the storage position and has a top opening 1191 for convenient use. The first cover body 11A is pivotally connected to the base body 111 and is used to cover the top opening 1181 of the first pocket structure 118. The second cover body 11B is pivotally connected to the base body 111 and is used to cover the top opening 1191 of the second pocket structure 119.

[0057] Specifically, a first stepped structure 1115 and a second stepped structure 1116 are formed on the base body 111. The protruding length of the lower part of the first stepped structure 1115 is less than the protruding length of the upper part of the first stepped structure 1115. Preferably, the protruding length of the first stepped structure 1115 gradually decreases from top to bottom. The protruding length of the lower part of the second stepped structure 1116 is less than the protruding length of the upper part of the second stepped structure 1116. Preferably, the protruding length of the second stepped structure 1116 gradually decreases from top to bottom. The first stepped structure 1115 and the second stepped structure 1116 are respectively covered by the first plate member 112 and the second plate member 113. The first through slot 1113 is formed between the first stepped structure 1115 and the first plate member 112. The second through slot 1114 is formed between the second stepped structure 1116 and the second plate member 113. Furthermore, a first convex rib (not shown in the figure) protruding downward is formed on the first plate member 112. The first convex rib is located at the lower part corresponding to the first stepped structure 1115. A second convex rib 1131 protruding downward is formed on the second plate member 113. The second convex rib 1131 is located at the lower part corresponding to the second stepped structure 1116. When the fixing strap 114 moves toward the storage position, the first convex rib and the second convex rib 1131 guide the fixing strap 114 downward away from the third plate member 115. In other words, through the above arrangement, the fixing strap 114 located in the storage position is not tightened by the third plate member 115.

[0058] In addition, a recess 1117 is formed on the base body 111. The recess 1117 is located between the first stepped structure 1115 and the second stepped structure 1116 and is used to accommodate the third plate member 115 in the closed position. The third plate member 115 drives the fixing belt 114 or a seat belt portion of the vehicle into the recess 1117 to tighten the fixing belt 114 or the seat belt of the vehicle, thereby eliminating the slack of the fixing belt 114 or the seat belt of the vehicle. The child restraint base 11 further includes a first engaging member 11C and a second engaging member 11D. The first engaging member 113 is disposed on the third plate member 115, and the second engaging member 11D is disposed on the base body 111. When the third plate member 115 is in the closed position, the first engaging member 11C and the second engaging member 11D engage with each other to prevent the third plate member 115 from leaving the closed position. Preferably, the child restraint base 11 further includes an elastic member 11E installed between the third plate member 115 and the base body 111. The elastic member 11E is used to give the third plate member 115 a potential energy to pivot toward the open position.

[0059] As Figure 2 shown, when the user desires to fix the child restraint base 11 to the vehicle using the fixing belt 114, the third plate member 115 can be first operated to pivot about its pivot axis 1151 in the first pivot direction R1 to the open position. Then, the fixing belt 114 can slide along the first through slot 1113 and the second through slot 1114 to the use position and pass through the first channel 1111 and the second channel 1112 to connect to the vehicle through the first fixing hook 116 and the second fixing hook 117. Furthermore, the third plate member 115 can be operated to pivot about its pivot axis 1151 from the open position to the closed position in the second pivot direction R2 opposite to the first pivot direction R1 to tighten the fixing belt 114, thereby eliminating the slack of the fixing belt 114, and further achieving the purpose of fixing the child restraint base 11 to the vehicle to restrict the movement of the child restraint base 11 relative to the vehicle.

[0060] Please refer to Figure 3 and Figure 6 , Figure 6 FIG. is a partial schematic structural view of the child restraint base 11 according to an embodiment of the present invention when the seat belt 2 of the vehicle is tightened by the third plate member 115. As Figure 3 and Figure 6As shown, when a user desires to use the seat belt 2 of a vehicle to fix the child restraint base 11 to the vehicle, the third plate member 115 can be first operated to pivot about its pivot axis 1151 in the first pivot direction R1 to an open position. Then, the fixing belt 114 can slide along the first slot 1113 and the second slot 1114 to a storage position, and the first fixing hook 116 and the second fixing hook 117 can be respectively received in the first pocket structure 118 and the second pocket structure 119. When the fixing belt 114 is in the storage position, the fixing belt is away from the path of the seat belt of the vehicle and is below the path of the seat belt of the vehicle. At this time, the user can pass the seat belt of the vehicle through the first channel 1111 and the second channel 1112 without interference with the fixing belt 114. It should be noted that when the seat belt of the vehicle passes through the first channel 1111 and the second channel 1112, the seat belt of the vehicle is laid on the first plate member 112 and the second plate member 113 and does not pass through the first slot 1113 and the second slot 1114. After the seat belt of the vehicle passing through the first channel 1111 and the second channel 1112 is fastened, the user can operate the third plate member 115 to pivot from the open position to the closed position about its pivot axis 1151 in the second pivot direction R2 to tighten the seat belt of the vehicle, thereby eliminating the slack of the seat belt of the vehicle, and further achieving the purpose of fixing the child restraint base 11 to the vehicle to restrict the movement of the child restraint base 11 relative to the vehicle.

[0061] Compared with the prior art, the present invention forms a first through slot and a second through slot for the fixing belt to slide through by using a first plate member, a second plate member and a base body. When a user wants to fix the child restraint base on a vehicle by using the fixing belt, the third plate member can be operated to pivot to the open position, and then the fixing belt can be operated to slide along the first through slot and the second through slot to the use position and pass through the first channel and the second channel, so as to connect the vehicle through the first fixing hook and the second fixing hook. Then, the third plate member can pivot from the open position to the closed position to tighten the fixing belt, thereby eliminating the slack of the fixing belt, and further achieving the purpose of fixing the child restraint base on the vehicle to limit the movement of the child restraint base relative to the vehicle. When a user wants to fix the child restraint base on a vehicle by using the seat belt of the vehicle, the third plate member can be operated to pivot to the open position, and then the fixing belt can be operated to slide along the first through slot and the second through slot to the storage position, so as to allow the seat belt of the vehicle to pass through the first channel and the second channel without interfering with the fixing belt. When the seat belt of the vehicle passes through the first channel and the second channel, the seat belt of the vehicle is laid on the first plate member and the second plate member without passing through the first through slot and the second through slot. After the seat belt of the vehicle passing through the first channel and the second channel is fastened, the third plate member can pivot from the open position to the closed position to tighten the seat belt of the vehicle, thereby eliminating the slack of the seat belt of the vehicle, and further achieving the purpose of fixing the child restraint base on the vehicle to limit the movement of the child restraint base relative to the vehicle. Therefore, the present invention has the advantage of simple operation.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
