Figure 3 This is a partial structural diagram of the child restraint base 11 according to an embodiment of the present invention when the fixing belt 114 is in the storage position. Figure 4 FIG. 1 is another partial structural diagram of the child restraint base 11 according to an embodiment of the present invention. Figure 5 FIG. 1 is a schematic diagram of the third plate 115 according to an embodiment of the present invention. Figures 2 to 5 As shown, the child restraint base 11 includes a base body 111, a first plate 112, a second plate 113, a fixing belt 114, a third plate 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 to install the child restraint vehicle 12. A first channel 1111 and a second channel 1112 are formed on both sides of the base body 111 for the fixing belt 114 or a safety belt of a vehicle to pass through. The first plate 112 is arranged on the base body 111, and a first through groove 1113 is formed between the first plate 112 and the base body 111. The second plate 113 is arranged on the base body 111 and is separated from the first plate 112. A second through groove 1114 is formed between the second plate 113 and the base body 111.

[0056] The fixing belt 114 is passed through the first through groove 1113 and the second through groove 1114 and can slide along the first through groove 1113 and the second through groove 1114 between the use position and the storage position. The third plate 115 is arranged between the first plate 112 and the second plate 113 and can pivot between the open position and the closed position relative to the base body 111 to eliminate the slack of the fixing belt 114 or the safety belt of the vehicle. The first fixing hook 116 and the second fixing hook 117 are connected to the two ends of the fixing belt 114 and are used to connect the vehicle. The first pocket structure 118 and the second pocket structure 119 are located at the outer edge of the base body 111 and at the two front sides of the base body 111. The first pocket structure 118 is used to accommodate the first fixing hook 116 when the fixing belt 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 belt 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 step structure 1115 and a second step structure 1116 are formed on the base body 111, and the protruding length of the lower part of the first step structure 1115 is smaller than the protruding length of the upper part of the first step structure 1115. Preferably, the protruding length of the first step structure 1115 can gradually decrease from top to bottom, and the protruding length of the lower part of the second step structure 1116 is smaller than the protruding length of the upper part of the second step structure 1116. Preferably, the protruding length of the second step structure 1116 gradually decreases from top to bottom. The first step structure 1115 and the second step structure 1116 are respectively covered by the first plate 112 and the second plate 113, and the first through groove 1113 is formed between the first step structure 1115 and the first plate 112, and the second through groove 1114 is formed between the second step structure 1116 and the second plate 113. Furthermore, a first convex rib (not shown in the figure) protruding downward is formed on the first plate 112, and the first convex rib is located at the lower part corresponding to the first step structure 1115. A second convex rib 1131 protruding downward is formed on the second plate 113, and the second convex rib 1131 is located at the lower part corresponding to the second step structure 1116. When the fixing belt 114 moves toward the storage position, the first convex rib and the second convex rib 1131 guide the fixing belt 114 downward away from the third plate 115. In other words, through the above arrangement, the fixing belt 114 at the storage position will not be tightened by the third plate 115.

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

[0059] like Figure 2 As shown, when the user wants to use the fixing belt 114 to fix the child restraint base 11 on the vehicle, the user can first operate the third plate 115 to pivot to the open position along the first pivot direction R1 around the pivot axis 1151. 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 115 can be operated to pivot from the open position to the closed position along the second pivot direction R2 opposite to the first pivot direction R1 around the pivot axis 1151 to tighten the fixing belt 114, thereby eliminating the slack of the fixing belt 114, and thus achieving the purpose of fixing the child restraint base 11 on the vehicle to restrict the movement of the child restraint base 11 relative to the vehicle.

[0060] See also Figure 3 and Figure 6 , Figure 6 This is a partial structural diagram of the child restraint base 11 of the embodiment of the present invention when the safety belt 2 of the vehicle is tightened by the third plate 115. Figure 3 and Figure 6As shown, when the user wants to use the safety belt 2 of the vehicle to fix the child restraint base 11 on the vehicle, the user can first operate the third plate 115 to pivot around its pivot axis 1151 along the first pivot direction R1 to the open position. Then, the fixing belt 114 can slide along the first through groove 1113 and the second through groove 1114 to the storage position, and the first fixing hook 116 and the second fixing hook 117 can be respectively accommodated in the first pocket structure 118 and the second pocket structure 119. When the fixing belt 114 is at the storage position, the fixing belt is away from the path of the safety belt of the vehicle and is located below the path of the safety belt of the vehicle. At this time, the user can pass the safety belt of the vehicle through the first channel 1111 and the second channel 1112 without interfering with the fixing belt 114. It is worth noting that when the safety belt of the vehicle passes through the first channel 1111 and the second channel 1112, the safety belt of the vehicle is laid on the first plate 112 and the second plate 113 without passing through the first through slot 1113 and the second through slot 1114. After the safety belt of the vehicle passing through the first channel 1111 and the second channel 1112 is fastened, the user can operate the third plate 115 to pivot from the open position to the closed position along the second pivot direction R2 around the pivot axis 1151 thereof to tighten the safety belt of the vehicle, thereby eliminating the slack of the safety belt of the vehicle, and further achieving the purpose of fixing the child restraint base 11 on 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 uses the first plate, the second plate and the base body to form the first through-groove and the second through-groove for the fixing belt to slide through. When the user wants to fix the child restraint base on the vehicle using the fixing belt, the third plate can be operated to pivot to the open position, and then the fixing belt can be operated to slide along the first through-groove and the second through-groove to the use position and pass through the first channel and the second channel to connect the vehicle through the first fixing hook and the second fixing hook. Then, the third plate can be pivoted from the open position to the closed position to tighten the fixing belt, thereby eliminating the looseness of the fixing belt, thereby 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 the user wants to fix the child restraint base on the vehicle using the safety belt of the vehicle, the third plate can be operated to pivot to the open position, and then the fixing belt can be operated to slide along the first through-groove and the second through-groove to the storage position, so as to allow the safety belt of the vehicle to pass through the first channel and the second channel without interfering with the fixing belt. When the safety belt of the vehicle passes through the first channel and the second channel, the safety belt of the vehicle is laid on the first plate and the second plate without passing through the first through groove and the second through groove. After the safety belt of the vehicle passing through the first channel and the second channel is fastened, the third plate can be pivoted from the open position to the closed position to tighten the safety belt of the vehicle, thereby eliminating the slack of the safety belt of the vehicle, thereby achieving the purpose of fixing the child restraint base on the vehicle to restrict the movement of the child restraint base relative to the vehicle. Therefore, the present invention has the advantage of simple operation.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
