[0067] To make the technical contents, structural features, purposes and effects of the present application clear, the following will be described in detail in connection with the embodiments and the accompanying drawings.

[0068] Please refer to Figures 1 to 3The present application provides a head protection device 100, which is adapted to be sleeved on the outside of the shoulder strap 300 of a baby carrier 200 and the adjusting buckle 400 around the shoulder strap 300, and does not slide relative to the adjusting buckle 400 and the shoulder strap 300 around the adjusting buckle 400. In the present application, the baby carrier 200 of the present application includes, but is not limited to, for example, a stroller, a baby basket, a sleeping box, a safety seat and a baby chair. Specifically, the baby carrier 200 of the present application includes a seat body 500 and a backrest 600 connected to the seat body 500, and two shoulder straps 300 are symmetrically connected between the seat body 500 and the backrest 600. In order to adapt to the use of babies of different ages and body sizes, the shoulder strap 300 is length-adjustable, and the adjusting buckle 400 is used for adjusting the length of the shoulder strap 300, so that the baby sitting in the baby carrier 200 is adaptively fixed by the two shoulder straps 300, to ensure the safety of use. The adjusting buckle 400 is specifically selected as a day buckle or an eye buckle, which is convenient to use and economical and practical. According to the needs, some of the baby carriers 200 are also symmetrically arranged with two waist straps 700 on the left and right opposite sides of the seat body 500, and a crotch strap 800 is arranged at the opposite center of the seat body 500, that is, at the position between the two legs of the baby, and the two shoulder straps 300, the two waist straps 700 and the crotch strap 800 are correspondingly connected to a connecting buckle 900, so that the connecting buckle 900 is respectively detachably connected to the seat body 500, and the connecting buckle 900 is generally located at the position of the waist and abdomen of the baby during use. More specifically, the head protection device 100 of the present application is detachably wrapped on the outside of the shoulder strap 300:

[0069] In combination with Figure 1 and Figure 2, shoulder strap 300 has a first structure: including upper shoulder strap 301 and lower shoulder strap 302 which are wound on adjusting buckle 400, upper shoulder strap 301 and lower shoulder strap 302 are correspondingly wound on opposite upper and lower sides of adjusting buckle 400, and there is a gap 401 between upper shoulder strap 301 and lower shoulder strap 302 which are wound on adjusting buckle 400. Upper shoulder strap 301 includes upper connecting end 301a and lower connecting end 301b which are located at two ends of upper shoulder strap 301, upper connecting end 301a is connected with opposite upper end 600a of backrest 600, and lower connecting end 301b is connected with opposite middle upper end 600b of backrest 600 after being wound on adjusting buckle 400. Lower shoulder strap 302 has connecting end 302a and free end 302b which are located at two ends of lower shoulder strap 302, connecting end 302a is connected with seat body 500, specifically, buckle connected at connecting end 302a is detachably connected on connecting buckle 900, so that lower shoulder strap 302 is connected with seat body 21; free end 302b of lower shoulder strap 302 is wound on adjusting buckle 400, so that adjusting part 3021 is formed between free end 302b and adjusting buckle 400, and connecting part 3022 is formed between connecting end 302a and adjusting buckle 400. In use, by pulling adjusting part 3021, relative length of connecting part 3022 can be adjusted, so that length of whole shoulder strap 300 is changed to adapt to use requirements of different young children.

[0070] In combination Figure 1 and Figure 3 The second structure of shoulder strap 300 is mainly different from the first structure in that lower connecting end 301b of upper shoulder strap 301 is folded upward to be connected with strap body of upper shoulder strap 301 after being wound on adjusting buckle 400, so that through hole 3011 is formed between lower connecting end 301b and upper shoulder strap 301 on opposite back surface of adjusting buckle 400, other parts of shoulder strap 300 of this structure are basically consistent with the first structure, and will not be described here, and in use, length of connecting part 3022 is adjusted by pulling adjusting part 3021, so that length of whole shoulder strap 300 is changed.

[0071] It should be noted that in the above two structures of the shoulder strap 300, the lower connecting end 301b of the upper shoulder strap 301 is fixedly connected with the corresponding opposite middle upper end 600b of the backrest 600 or the strap body of the upper shoulder strap 301, such as a sewing connection, a gingham buckle or a goal buckle. The upper connecting end 301a of the upper shoulder strap 301 can be sewingly connected to the opposite upper end 600a of the backrest 600, or can be detachably connected to the backrest 600 by a buckle, which is relatively simple in structure. Of course, the upper connecting end 301a can also pass through the backrest 600 and be wound in a webbing winder arranged on the back of the backrest 600, thereby increasing the length of the shoulder strap 300 and effectively improving the adaptability of the shoulder strap 300. In addition, although the shoulder strap 300 of the present application is exemplified as the above structure including the split upper shoulder strap 301 and the lower shoulder strap 302, it is not limited thereto. When the shoulder strap 300 is simplified as an integrated structure connected between the seat body 500 and the backrest 600, as long as the head protection device 100 is still wrapped outside the shoulder strap 300 and the adjusting buckle 400, and is clamped with the adjusting buckle 400 and the shoulder strap 300 at the adjusting buckle 400, the relative sliding can be realized.

[0072] The following Figures 2 to 8 The structure of the first embodiment of the head protection device 100 of the present application will be described below:

[0073] Referring to Figure 4 and Figure 5 , the head protection device 100 includes a protective sheet 10 and a connecting piece 20 and a positioning piece 30 arranged on the protective sheet 10. The left and right side ends of the protective sheet 10 are detachably connected by the connecting piece 20, so as to be sleeved outside the shoulder strap 300 and the adjusting buckle 400. The positioning piece 30 is used to clamp the adjusting buckle 400 or / and the shoulder strap 300 around the adjusting buckle 400, so that the adjusting buckle 400 and the shoulder strap 300 around the adjusting buckle 400 are constantly wrapped in the protective sheet 10. In use, the head protection device 100 is first placed between the backrest 600 and the shoulder strap 300, and the position of the adjusting buckle 400 is located, then the positioning piece 30 is clamped with the adjusting buckle 400 or / and the shoulder strap 300 around the adjusting buckle 400, and one of the opposite left and right side ends of the protective sheet 10 is bent or wound towards the other, so that the left and right side ends of the protective sheet 10 are relatively connected or coincided and fixed by the connecting piece 20, thereby being conveniently and quickly sleeved outside the adjusting buckle 400 and the shoulder strap 300 around the adjusting buckle 400. In this embodiment, the protective sheet 10 is arranged relatively along the longitudinal direction of the shoulder strap 300, so as to be wrapped outside the adjusting buckle 400 and the wrapping place of the shoulder strap 300 around the adjusting buckle 400, and the extension place of the shoulder strap 300 connected with the wrapping place, and the protective sheet 10 is relatively long, so as to be wrapped outside the shoulder strap 300 in a longer range, and the safety and comfort of use are better.

[0074] Referring to Figure 4 and Figure 5 The protective sheet 10 is sheet-shaped, substantially rectangular, relatively soft and elastic. Specifically, the protective sheet 10 comprises a wrapping layer 11 and a fitting layer 12 which are connected as a whole by sewing. The wrapping layer 11 is used to contact the shoulder strap 300 and the adjusting buckle 400, and the fitting layer 12 is used to contact the head and neck of the baby. Specifically, the protective sheet 100 further comprises a buffer layer (not shown in the figure because it is hidden between the wrapping layer 11 and the fitting layer 12), which is arranged between the wrapping layer 11 and the fitting layer 12, and the wrapping layer 11, the buffer layer and the fitting layer 12 are connected as a whole by sewing. Among them, the buffer layer can be arranged on the side opposite to the other one of the wrapping layer 11 and the fitting layer 12, that is, the wrapping layer 11 or / and the fitting layer 12 itself has a buffer layer. Of course, a buffer layer can also be added, which is connected with the wrapping layer 11 and the fitting layer 12 by sewing. In order to facilitate processing and use, the edges of the wrapping layer 11 and the fitting layer 12 can also be connected as a whole by sewing, and the wrapping layer 11 is provided with a filling port 111, and the buffer layer can be detachably filled between the wrapping layer 11 and the fitting layer 12 through the filling port 111, so as to facilitate disassembly and washing, and use more healthily. It should be noted that when the wrapping layer 11 or / and the fitting layer 12 itself has a buffer layer, or the buffer layer is connected with the wrapping layer 11 and the fitting layer 12 by sewing, the filling port 111 corresponds to a pressure line sewn on the central axis of the protective sheet 10, so as to facilitate the folding of the protective sheet 10. Among them, the wrapping layer 11 and the fitting layer 12 can be made of at least one of fiber fabric, cotton material or leather material, and the buffer layer can be made of at least one of latex, memory cotton or silica gel material.

[0075] Referring to Figure 5 The connecting piece 20 is specifically arranged at the edges of the opposite left side and the opposite right side of the protective sheet 10. The number of the connecting piece 20 can be multiple, and the multiple connecting pieces 20 can be arranged at intervals along the longitudinal direction of the protective sheet 10, so that the protective sheet 10 is more stable and reliable when being sleeved on the shoulder strap 300 through the setting of multiple connecting points. Specifically, the connecting piece 20 is any one of a fixing buckle and a fixing hole, a buckle, a rope and a magic tape which can be detachably matched. In this embodiment, the connecting piece 20 is selected as a snap fastener, which comprises male buckles 21 and female buckles 22 arranged at intervals along the transverse direction of the protective sheet 10. Through the buckling or separation of the male buckles 21 and the female buckles 22, the protective sheet 10 is simply and conveniently mounted or dismounted on the shoulder strap 300, which is convenient to use and effectively reduces the manufacturing cost.

[0076] Referring to Figure 4 and Figure 5The positioning member 30 can be clamped with the shoulder strap 300 along the transverse direction of the shoulder strap 300. Specifically, in the embodiment, the positioning member 30 comprises a clamping piece 31 arranged on the protective sheet 10, which is used to be clamped with the shoulder strap 300 around the adjusting buckle 400 from the opposite front surface or the opposite back surface of the adjusting buckle 400, specifically the upper shoulder strap 301 of the shoulder strap 300. Specifically, the edge of the opposite left end or the opposite right end of the protective sheet 10 is recessed towards the opposite side to form a gap 13, so that a clamping piece 31 is formed on the protective sheet 13 due to the division of the gap 13. The gap 13 is specifically arranged at the opposite upper end of the opposite left end or the opposite right end of the protective sheet 10, and the closed end of the gap 13 is located near the center line of the protective sheet 10. The width of the gap 13 corresponds to the thickness of the shoulder strap 300, so as to facilitate the clamping between the clamping piece 31 and the shoulder strap 300.

[0077] Referring to Figure 4 and Figure 5 , preferably, the positioning member 30 further comprises a closing member 32 arranged at the opening end of the gap 13, which is used to open and close the opening end of the gap 13, so as to strengthen the clamping between the clamping piece 31 and the shoulder strap 300. Specifically, the closing member 32 is any one of detachable fixing buckles and fixing holes, buckles, ropes and magic tapes. In the embodiment, the closing member 32 is selected as a magic tape, which comprises a female tape 321 and a male tape 322 arranged on the opposite side walls of the gap 13. By the combination or separation of the two, the opening and closing of the gap 13 are realized simply and conveniently, which is convenient to use and effectively reduces the manufacturing cost.

[0078] Referring to Figure 4 and Figure 5 , the head protection device 100 of the application further comprises a limiting member 40, which is sewn to the protective sheet 10 below the positioning member 30 and has a limiting space for the shoulder strap 300 to pass through, so as to constrain the shoulder strap 300 wrapped in the protective sheet 10. Not only can the connection between the protective sheet 10 and the shoulder strap 300 be further strengthened, but also the sliding direction of the shoulder strap 300 can be limited, so that the whole shoulder strap 300 is more orderly. Specifically, the limiting member 40 is annular or semi-annular and has a certain elasticity. In the embodiment, the two ends of the semi-annular limiting member 40 are sewn to the protective sheet 40, so as to form a limiting space for the shoulder strap 300 to pass through between the limiting member 40 and the protective sheet 10, which correspondingly reduces the manufacturing cost.

[0079] In combination with Figure 2 , Figure 5 and Figure 6When the head protection device 100 of the present embodiment is used on the child carrier 200 with the shoulder belt 300 of the first structure, the protector sheet 10 is integrally detachably wrapped outside the adjustment buckle 400 and the adjustment portion 3021 and the connecting portion 3022 of the upper shoulder belt 301 and the lower shoulder belt 302 wound around the adjustment buckle 400, the upper shoulder belt 301 between the opposite middle upper end 600b of the backrest 600 and the adjustment buckle 400 is inserted into the gap 13, so that the clamping sheet 31 clamps the upper shoulder belt 301 at the back of the adjustment buckle 400 and the upper shoulder belt 301 wound around the adjustment buckle 400, and the clamping surface 311 of the clamping sheet 31 clamped with the upper shoulder belt 301 is a plane. When the adjustment portion 3021 is pulled to adjust the length of the shoulder belt 300, the clamping sheet 31 is always clamped with the upper shoulder belt 301, so that the adjustment buckle 400 and the adjustment portion 3021 and the connecting portion 3022 of the upper shoulder belt 301 and the lower shoulder belt 302 wound around the adjustment buckle 400 are always wrapped in the protector sheet 10, which is safe and comfortable to use. If the closing member 32 is used, the clamping effect is better, and if the adjustment portion 3021 and the connecting portion 3022 of the lower shoulder belt 302 on the adjustment buckle 400 are placed in the limiting member 40, the use effect is better.

[0080] In combination Figure 2 , Figure 5 and Figure 7 , when the head protection device 100 of the present embodiment is used on the child carrier 200 with the shoulder belt 300 of the first structure, another clamping method can also be used, which is different from the clamping method shown in Figure 6 : the clamping position of the clamping sheet 31 and the upper shoulder belt 301 is different. At this time, the upper shoulder belt 301 between the lower connecting end 301b and the adjustment buckle 400 is inserted into the gap 13, and the clamping sheet 31 is clamped with the upper shoulder belt 301 at the opposite front of the adjustment buckle 400 and the winding end A of the adjustment buckle 400, that is, the clamping sheet 31 is clamped at the position between the upper shoulder belt 301 and the winding end A of the adjustment buckle 400, so that the clamping sheet 31 is always clamped with the upper shoulder belt 301 at the adjustment buckle 400, so that the adjustment buckle 400 and the adjustment portion 3021 and the connecting portion 3022 of the upper shoulder belt 301 and the lower shoulder belt 302 wound around the adjustment buckle 400 are always wrapped in the protector sheet 10, which is safe and comfortable to use. In the present specific embodiment, the clamping surface 311 of the clamping sheet 31 is preferably an inclined surface, so as to effectively improve the firmness of the clamping, and if the closing member 32 or / and the limiting member 40 is used at this time, the clamping effect is better.

[0081] In combination Figure 3 , Figure 5 and Figure 8 , when the head protection device 100 of the present embodiment is used on the child carrier 200 with the shoulder belt 300 of the second structure, and Figure 6The difference in the illustrated snap-fit ​​method is that, while the snap-fit ​​piece 31 is still snap-fitted to the upper shoulder strap 301 wound between the adjustment buckle 400 and the lower connecting end 301b on the opposite back surface of the adjustment buckle 400, the snap-fit ​​piece 31 is specifically inserted into the through-hole 3011, and the notch 13 is snap-fitted to the upper shoulder strap 301 wound between the adjustment buckle 400 and the lower connecting end 301b. This double snap-fit ​​method effectively enhances the secureness of the snap-fit ​​connection. In this case, the snap-fit ​​effect is further enhanced when used in conjunction with the closure member 32 and / or the stopper 40. When the buckle 400 is in the locked position, the buckle 31 is in the locked position, and the buckle 31 is in the locked position, so that the buckle 31 is locked with the buckle 301 at the buckle 400.

[0082] The following combination Figures 9 to 11 , the structure of the second embodiment of the head protection device 100 of the present invention is described:

[0083] The primary difference between this embodiment and the first embodiment lies in that the guard plate 10 is arranged relatively along the width of the shoulder strap 300, thereby wrapping only around the adjustment buckle 400 and the outside of the shoulder strap 300 connected to the adjustment buckle 400. In this embodiment, the guard plate 10 is relatively short, primarily wrapping around the outside of the adjustment buckle 400, and only around the shorter portion of the shoulder strap 300, thereby saving costs. Accordingly, the notch 13 is located at the center of the left or right end of the guard plate 10. The remaining structure of the head protector 100 in this embodiment is substantially identical to that of the first embodiment and will not be further described here.

[0084] The following combination Figures 12 to 14 , the structure of the third embodiment of the head protection device 100 of the present invention is described:

[0085] The main difference between the present embodiment and the first embodiment is that the structure of the positioning member 30 is different, and the protector 10 does not need to be provided with the notch 13 and the closing member 32. In the present embodiment, the positioning member 30 can be connected with the adjusting buckle 400 along the thickness direction of the shoulder strap 300. The positioning member 30 includes a hanging piece 33 arranged on the protector 10, which is used to be inserted into the adjusting buckle 400 and connected with the adjusting buckle 400. Specifically, the hanging piece 33 includes a connecting portion 331 and a connecting head 332. One end of the connecting portion 331 is sewn on the protector 10, and the other end of the connecting portion 331 is sewn with the connecting head 332. The connecting head 332 can be inserted into the adjusting buckle 400 from the opposite back surface to the opposite front surface of the adjusting buckle 400, and then connected with the adjusting buckle 400 along the longitudinal direction of the adjusting buckle 400, specifically through the insertion gap 401 between the upper shoulder strap 301 and the lower shoulder strap 302 arranged on the adjusting buckle 400, to be connected with the adjusting buckle 400. If the adjusting part 3021 and the connecting part 3022 of the lower shoulder strap 302 on the adjusting buckle 400 are inserted into the limiting member 40, the use effect is better. Specifically, the connecting head 332 is in the shape of T or bow. Preferably, the connecting head 332 is provided with a supporting member 333, which has a certain hardness and elasticity, and is used to prevent the connecting head 332 from being separated from the adjusting buckle 400. Specifically, the supporting member 333 is made of plastic sheet.

[0086] It should be noted that, in combination with Figure 2 and Figure 3 , in the present embodiment, whether the shoulder strap 300 of the first structure is sleeved or the shoulder strap 300 of the second structure is sleeved, no matter how the shoulder strap 300 slides relative to the adjusting buckle 400, the hanging piece 33 is always connected with the adjusting buckle 400, so that the protector 10 and the adjusting buckle 400 do not slide relative to each other, so that the adjusting buckle 400 and the adjusting part 3021 and the connecting part 3022 of the upper shoulder strap 301 and the lower shoulder strap 302 arranged on the adjusting buckle 400 are always wrapped in the protector 10, which is safer and more comfortable to use.

[0087] The structure of the fourth embodiment of the head protection device 100 of the present application will be described below in combination with Figures 15 to 17

The positioning member 30 not only includes the connecting piece 31, but also includes the hanging piece 33 in the third embodiment. At this time, the hanging piece 33 is arranged at the edge of the notch 13, and through double connection, the firmness of the connection between the protective sheet 10 and the shoulder strap 300 and the adjusting buckle 400 is further enhanced, thereby further improving the safety and comfort of use. The specific connection structure between the connecting piece 31 and the upper shoulder strap 301 and between the hanging piece 33 and the adjusting buckle 400 is consistent with the corresponding structure of the first embodiment and the third embodiment, and will not be repeated here.

[0089] Compared with the prior art, the head protection device 100 of the present application includes the connecting member 20 and the positioning member 30 arranged on the protective sheet 10. The protective sheet 10 is detachably sleeved on the adjusting buckle 400 and the shoulder strap 300 around the adjusting buckle 400 outside. Since the shoulder strap 300 is adjustably connected between the backrest 600 and the seat body 500 of the child carrier 200, combined with the connection of the positioning member 30 with the adjusting buckle 400 or / and the shoulder strap 300 around the adjusting buckle 400, in actual use, whether the protective sheet 10 is bumped by the child during the riding process or the shoulder strap 300 slides relative to the adjusting buckle 400 during the length adjustment process, the protective sheet 10 is always connected with the adjusting buckle 400 or / and the shoulder strap 300 around the adjusting buckle 400 through the positioning member 30, so that there is no relative sliding between the protective sheet 10 and the sleeved shoulder strap 300 and adjusting buckle 400, so that the adjusting buckle 400 and the shoulder strap 300 around the adjusting buckle 400 are always wrapped in the protective sheet 10, thereby effectively improving the safety and comfort of use. The head protection device 100 of the present application is simple in structure, easy to use and safe and reliable, and effectively protects the safety and comfort of use of the child carrier 200 with the head protection device 100.
