[0028] refer to Figure 5 , Figure 6 When the child safety seat is in group 0-1, the five-point safety belt on the safety seat body 30 should be used. When the child is in group 2-3, as the child grows older and bigger, the three-point safety belt on the car seat can be used in conjunction with the belly belt guide hook. However, existing cross-group combination child seats, such as 0+1+2 group seats and 0+1+2+3 group seats, are only provided with five-point buckles, and no belly belt guide hooks are provided.
[0029] To this end, the present application provides a safety belt connection device, referring to Figure 1-Figure 4As shown, it includes a first connecting component 10 and a second connecting component 20, the first connecting component 10 includes a first connecting belt 11 and a first joint 12 connected to each other, the second connecting component 20 includes a second connecting belt 21 and a second joint 22 connected to each other, the side of the first connecting belt 11 away from the first joint 12 and the side of the second connecting belt 21 away from the second joint 22 are both suitable for connecting with the safety seat body 30, and at least one of the first connecting belt 11 and the second connecting belt 21 is provided with a through hole 2a, and the first joint 12 and the second joint 22 can switch their positions relative to the safety seat body 30 through the through hole 2a. It can be understood that the first connecting belt 11 and the second connecting belt 21 are made of flexible materials and are easy to deform, so that the joints on the connecting belts can easily pass through the through hole 2a. Among them, the first joint 12 and the second joint 22 are joints with different structures, for example, one is a belly belt guide hook and the other is a five-point buckle, so as to be respectively suitable for different safety belt usage conditions. The first joint 12 can be specifically a five-point buckle, and the second joint 22 can be specifically a belly belt guide hook.
[0030] refer to Figure 3 , Figure 5 As shown, when the child safety seat is in the 0 group or 1 group use state, the five-point buckle and the five-point safety belt can be used to restrain the child, and the belly belt guide hook is stored and hidden in the safety seat body 30. Figure 4 , Figure 6 As shown, when the child safety seat is in the 2-group or 3-group use state, the belly belt guide hook can be used in conjunction with the three-point safety belt to restrain the child, and the five-point buckle can be stored and hidden. The problem that the belly belt guide hook cannot be used in the existing small group seats is solved. When the child grows up and needs to use the 2-group or 3-group, there is no need to remove the five-point buckle, but directly through the through hole 2a, the belly belt guide hook and the five-point buckle are wound backwards, and the rearward one is wound forward to switch the relative position of the belly belt guide hook and the five-point buckle. The entire safety belt connection device has a simple structure and is easy to use.
[0031] refer to Figure 4-Figure 6As shown, the present application can also provide a child safety seat using the safety belt connection device. In some embodiments, the safety belt connection device is arranged in the center along the left and right direction of the safety seat body 30. Further, the safety seat body 30 includes a shell 31 and a fixing portion 311 arranged on the shell 31, and a storage portion 312 arranged on the shell 31, the fixing portion 311 is suitable for connecting with the first connecting belt 11 and the second connecting belt 21, and the storage portion 312 is suitable for storing the first connector 12 and the second connector 22. When using the child safety seat, the first connector 12 and the second connector 22 can switch the front and rear positions relative to the safety seat body 30 through the through hole 2a, so that one of them can be connected to the safety belt and the other can be stored in the storage portion 312, and one of the connectors can be freely selected to be in a usable state, and the other connector can be properly stored.
[0032] In some specific embodiments, a Japanese-style buckle is provided on the first connecting belt 11 or the second connecting belt 21, and a mounting groove for engaging with the Japanese-style buckle is provided on the fixing portion 311, so that the first connecting component 10, the second connecting component 20 and the fixing portion 311 are detachably connected. Of course, the connection between the safety belt connecting device and the safety seat body 30 can also use other connection methods between the belly belt guide hook or the five-point buckle and the safety seat body 30.
[0033] In some specific embodiments, the storage portion 312 is configured as a storage box, which can selectively store at least one of the first connector 12 and the second connector 22 therein.
[0034] In some embodiments, only one of the first connecting belt 11 and the second connecting belt 21 is provided with a through hole 2a. It can be understood that only one of the first connecting belt 11 and the second connecting belt 21 is provided with a through hole 2a to achieve the purpose of switching the front and rear positions of the first joint 12 and the second joint 22. For example, if only the through hole 2a is provided on the first connecting belt 11, the second joint 22 and at least part of the second connecting belt 21 can pass through the through hole 2a and move from one side of the first connecting component 10 to the other opposite side, so that the relative front and rear positions of the first joint 12 and the second joint 22 can be interchanged. By saving the number of through holes 2a to be provided, it is conducive to simplifying the structure and reducing the processing and manufacturing costs. Of course, in some embodiments, a through hole 2a can also be provided on each of the first connecting belt 11 and the second connecting belt 21, and the first connecting component 10 and the second connecting component 20 can pass through each other's through hole 2a to achieve the front and rear position interchange.
[0035] In some embodiments, the through hole 2a extends along the length direction of the first connecting belt 11 to the side of the first connecting belt 11 away from the first joint 12, or extends along the length direction of the second connecting belt 21 to the side of the second connecting belt 21 away from the second joint 22. In other words, the through hole 2a extends along the length direction of the first connecting belt 11 or the second connecting belt 21 to the side close to the safety seat body 30, so that the joint and most of the connecting belts can pass through the through hole 2a. It is convenient for the connection component in a non-use state to be stored close to the safety seat body 30.
[0036] It can be understood that the first connecting belt 11 and the second connecting belt 21 are made of flexible materials, and the shape of the through hole 2a can change with the deformation of the connecting belt. In order to facilitate the joint to pass through the through hole 2a, the other end of the through hole 2a can extend to the side of the connecting belt close to the corresponding joint. In other words, the through hole 2a extends a long distance along the length direction of the connecting belt, so that the through hole 2a can have a larger aperture after deformation, which is convenient for the joint to pass through.
[0037] In some embodiments, the first connecting belt 11 is directly connected to the side away from the first joint 12 and the second connecting belt 21 is directly connected to the side away from the second joint 22, so that the first connecting component 10 and the second connecting component 20 form an integrated structure, and the integrated structure is further connected to the safety seat body 30. Compared with the first connecting component 10 and the second connecting component 20 being relatively independent and respectively installed on the safety seat body 30, the structure is simpler and easier to assemble.
[0038] In some embodiments, the second connecting belt 21 is provided with a through hole 2a, and the second connecting belt 21 includes a first belt section 211 and a second belt section 212. One end of the first belt section 211 is arranged on one side of the width direction of the first connecting belt 11, and one end of the second belt section 212 is arranged on the other side of the width direction of the first connecting belt 11. The other ends of the first belt section 211 and the second belt section 212 are both connected to the second joint 22, and a through hole 2a is formed between the first belt section 211 and the second belt section 212. The structure is simple, and the connection between the second connecting belt 21 and the second joint 22 is stable and reliable. In addition, the through hole 2a can have a larger aperture so that the first joint 12 and most of the first connecting belt 11 can pass through. In addition, the first belt section 211 and the second belt section 212 are separated from each other at one end away from the second joint 22, so that the bottom of the through hole 2a always has a certain width, which is convenient for quickly passing the first joint 12 through the through hole 2a.
[0039] In some embodiments, the first connecting belt 11 includes a first belt layer and a second belt layer arranged in parallel along the thickness direction, and one end of the first belt layer and the second belt layer are both suitable for connecting with the safety seat body 30, and the other end is connected with the first joint 12. Compared with the single-layer belt, the double-layer belt structure makes the connection structure between the first joint 12 and the first connecting belt 11 more stable and reliable.
[0040] In some embodiments, the first layer of belt body is provided with two connection points connected to the second layer of belt body at intervals along the length direction, so that the first layer of belt body and the second layer of belt body form a through-channel 11a suitable for the second connecting belt 21 to pass through between the two connection points, and the second connecting belt 21 includes a third section of belt body 213 that is passed through the through-channel 11a and connects the first section of belt body 211 and the second section of belt body 212. The first connecting component 10 and the second connecting component 20 are connected by the third section of belt body 213 passing through the through-channel 11a, forming an integrated structure for connection with the safety seat body 30, and the connection structure is simple.
[0041] In some embodiments, the first layer of belt body and the second layer of belt body can be formed by folding the same flexible belt, or by two or more belts. Similarly, the first section of belt body 211, the second section of belt body 212, and the third section of belt body 213 can be formed by the same flexible belt, or by two or more belts. Different belts or two parts of a belt can be connected by sewing, hot pressing, etc.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
