[Modes for carrying out the invention] 【0033】 The technical content, structural features, purpose of realization, and effects of the present invention will be described in detail below with reference to embodiments and drawings. 【0034】 Referring to Figures 1 to 3, the present invention provides a head protector 100 suitable for attachment to the outside of the shoulder straps 300 and the adjustable buckles 400 wrapped around the shoulder straps 300 of a child carrier 200, so that there is no relative sliding between the head protector 100, the adjustable buckles 400 and the shoulder straps 300 wrapped around the adjustable buckles 400. In this application, the child carrier 200 of the present invention includes, but is not limited to, a baby cart, a baby basket, a sleeping bag, a safety seat, a baby chair, and the like. Specifically, the child carrier 200 of the present invention includes a seat body 500 and a backrest 600 connected to the seat body 500. Two shoulder straps 300 are symmetrically connected between the seat body 500 and the backrest 600. To accommodate use by infants of different ages and sizes, the shoulder straps 300 are set to be length-adjustable, and the adjustment buckles 400 are used to adjust the length of the shoulder straps 300, thereby adaptively securing the infant seated in the infant carrier 200 via the two shoulder straps 300 and ensuring safety during use. Specifically, the adjustment buckles 400 are selected from two-eye buckles (8-type buckles) or three-eye buckles, which are easy to use, economical, and practical. Where necessary, some infant carriers 200 are symmetrically provided with two waist straps 700 located on the left and right sides of the seating area of ​​the seat body 500, respectively, and a crotch strap 800 is located at the relative center of the seating area of ​​the seat body 500, i.e., between the two legs of the corresponding infant. Two shoulder straps 300, two waist straps 700, and a crotch strap 800 are connected in accordance with the connecting buckle 900 so that they are detachably connected to the connecting buckle 900. When in use, the connecting buckle 900 is typically located at the waist and abdomen of the infant. More specifically, the head protection 100 of the present invention is detachably wrapped around the outside of the shoulder straps 300. 【0035】 In relation to Figures 1 and 2, each shoulder strap 300 includes a first structure, which includes an upper shoulder strap 301 and a lower shoulder strap 302 wound around an adjustment buckle 400, the upper shoulder strap 301 and the lower shoulder strap 302 being wound around the upper and lower opposing sides of the adjustment buckle 400, and further having a passage gap 401 between the upper shoulder strap 301 and the lower shoulder strap 302 wound around the adjustment buckle 400. The upper shoulder strap 301 includes an upper connecting end 301a and a lower connecting end 301b located at its head and tail, respectively. The upper connecting end 301a is connected to the relative upper end 600a of the backrest 600, and the lower connecting end 301b, after being wound around the adjustment buckle 400, is connected to the relative middle upper end 600b of the backrest 600. The lower shoulder strap 302 has connecting ends 302a and free ends 302b provided at its head and tail ends, respectively, with the connecting ends 302b connected to the seat body 500. Specifically, the lower shoulder strap 302 is detachably connected to the connecting buckle 900 via a buckle connected to the connecting end 302a, thereby enabling connection between the lower shoulder strap 302 and the seat body 500. After the free end 302b of the lower shoulder strap 302 is wound around the adjustment buckle 400, an adjustment portion 3021 is formed between the free end 302a and the adjustment buckle 400a, and a connecting portion 3022 is formed between the connecting end 302a and the adjustment buckle 400. When in use, the relative length of the connecting portion 3022 can be adjusted by pulling the adjustment portion 3021, thereby changing the overall length of the shoulder strap 300 to meet the usage requirements of different infants. 【0036】 When Figures 1 and 3 are combined, the second structure differs from the first structure of the shoulder strap 300. Here, the lower connecting end 301b of the upper shoulder strap 301 is wrapped around the adjustment buckle 400, then folded upwards and connected to the strap body of the upper shoulder strap 30. On the back side opposite the adjustment buckle 400, a through hole 3011 is formed between the lower connecting end 301b and the upper shoulder strap 301. All other parts of the shoulder strap 300 are substantially the same as the first structure and will not be described here. Specifically, when in use, the length of the connecting part 3022 is also adjusted by pulling the adjustment part 3021, changing the overall length of the shoulder strap 300. 【0037】 In the shoulder strap 300 of the two structures described above, the two connections between the lower connecting end 301b of the upper shoulder strap 301 and the corresponding relative intermediate upper end 600b of the backrest 600 or the belt body of the upper shoulder strap 301 are both fixed connections, such as a sewn connection, an octave buckle, or a three-eye buckle. The upper connecting end 301a of the upper shoulder strap 301 may be sewn to the relative upper end 600a of the backrest 600, or it may be detachably connected to the backrest 600 by a buckle with a relatively simple structure. Of course, the upper connecting end 301a can also pass through the backrest 600 and be wound around a webbing winder provided on the back of the backrest 600 to increase the length of the shoulder strap 300 and effectively enhance the adaptability of the shoulder strap 300. Furthermore, although the shoulder strap 300 of the present invention has been described as including an upper shoulder strap 301 and a lower shoulder strap 302 in a separate structure, the present invention is not limited thereto. Specifically, if the shoulder strap 300 is simplified to an overall configuration connected between the seat body 500 and the backrest 600, there is no relative slippage as long as the head protection 100 of the present invention still wraps around the outside of the shoulder strap 300 and the adjustment buckle 400 and clamps the adjustment buckle 400 to the shoulder strap 300. 【0038】 Next, the configuration of the head protection device 100 according to the first embodiment of the present invention will be described with reference to Figures 2 to 8. 【0039】 Referring to Figures 4 and 5, the head protection device 100 comprises a protective piece 10, a connecting member 20 and a positioning member 30 provided on the protective piece 10. Since both the left and right ends of the protective piece 10 are detachably connected by the connecting member 20, the protective piece 10 can be sleeved outside the shoulder strap 300 and the adjustment buckle 400. The positioning member 30 is used to clamp the adjustment buckle 400 and / or the shoulder strap 300 wrapped around the adjustment buckle 400, so that the adjustment buckle 400 and the shoulder strap 300 wrapped around the adjustment buckle 400 are always enclosed within the protective piece 10. When using the device, first, the head protection 100 is placed between the backrest 600 and the shoulder strap 300, and the position of the adjustment buckle 400 is aligned. Next, the positioning member 30 is clamped to the adjustment buckle 400 and / or the shoulder strap 300 wrapped around the adjustment buckle 400. Then, the relative left and right ends of the protective piece 10 are bent or rolled in one direction and the other, so that the left and right ends of the protective piece 10 come into contact with or overlap each other and are connected and fixed via the connecting member 20, thereby allowing the protective piece 10 to be easily and simply sleeved on the outside of the adjustment buckle 400 and the shoulder strap 300 wrapped around the adjustment buckle 400. In this embodiment, the protective piece 10 is positioned along the longitudinal direction of the shoulder strap 300 so as to wrap around the outside of the adjustment buckle 400 and the wrapped portion of the shoulder strap 300 wrapped around the adjustment buckle 400, and also wrap around the outside of the extended portion of the shoulder strap 300 connected to the wrapped portion. Therefore, the protective piece 10 can wrap around the outside of the shoulder strap 300 over a longer range, resulting in greater safety and comfort. 【0040】 As shown in Figures 4 and 5, the protective piece 10 is flat, substantially rectangular, relatively flexible, and has a certain elasticity. Specifically, the protective piece 10 includes a wrapping layer 11 and a fitting layer 12, which are sewn together as a whole. The wrapping layer 11 is used to contact the shoulder strap 300 and the adjustment buckle 400, and the fitting layer 12 is used to contact the infant's head and neck. Specifically, the protective piece 10 further includes a buffer layer (not shown as it is hidden between the wrapping layer 11 and the fitting layer 12). The buffer layer is provided between the wrapping layer 11 and the fitting layer 12, and the wrapping layer 11, the buffer layer, and the fitting layer 12 are sewn together as a whole. Here, the buffer layer is provided on at least one of the wrapping layer 11 and the fitting layer 12, on the side opposite to the other of the wrapping layer 11 or the fitting layer 12, i.e., the wrapping layer 11 and / or the fitting layer 12 itself may have a buffer layer. Of course, a buffer layer may be added and the buffer layer may be sutured to the entire wrapping layer 11 and fitting layer 12. To facilitate processing and use, the edges of the wrapping layer 11 and fitting layer 12 may be sutured together as a whole. The wrapping layer 11 is provided with a filling port 111, and the buffer layer is detachably filled between the wrapping layer 11 and fitting layer 12 via the filling port 111, making it easy to remove and clean, and allowing for healthier and more hygienic use. Note that if the wrapping layer 11 and / or fitting layer 12 itself has a buffer layer, or if the buffer layer is sutured to the entire wrapping layer 11 and fitting layer 12, the filling port 111 may be a recessed line sutured to the central axis of the protective piece 10 to facilitate the curvature of the protective piece 10. Here, the wrapping layer 11 and fitting layer 12 can be made from at least one of textile fabrics, cotton materials, or leather materials, and the buffer layer can be made from at least one of latex, memory foam, or silicone resin materials. 【0041】 Referring to Figure 5, the connecting members 20 are specifically provided on the relative left and relative right edges of the protective piece 10. There may be multiple connecting members 20, and the multiple connecting members 20 may be spaced apart in the longitudinal direction of the protective piece 10, and by providing multiple connection points, the protective piece 10 can be more securely sleeved to the shoulder strap 300. Specifically, the connecting members 20 may be any of the following: a fixing buckle and fixing hole that can be attached to and detached from each other, a buckle, a rope, and Velcro®. In this embodiment, the connecting member 20 is a snap button including a male button 21 and a female button 22 that are spaced apart in the width direction of the protective piece 10. The engagement and disconnection of the male button 21 and the female button 22 makes it easy and convenient to attach and detach the protective piece 10 to the shoulder strap 300, making it convenient to use and effectively reducing manufacturing costs. 【0042】 Referring to Figures 4 and 5, the positioning member 30 can clamp the shoulder strap 300 along the width direction of the shoulder strap 300. Specifically, in this embodiment, the positioning member 30 includes a clamping piece 31 provided on the protective piece 10, which is used to clamp the shoulder strap 300, specifically the upper shoulder strap 301 of the shoulder strap 300, which is wrapped around the adjustment buckle 400 from the relative front or relative rear surface of the adjustment buckle 400. Specifically, the edge of the relative left end or relative right end of the protective piece 10 is recessed on the opposite side to form a recess 13, and the clamping piece 31 is formed on the protective piece 10 by dividing the recess 13. Specifically, the recess 13 is provided at the relative upper end of the relative left end or relative right end of the protective piece 10, and the closed end of the recess 13 is located close to the center line of the protective piece 10. The width of the recess 13 corresponds to the thickness of the shoulder strap 300 in order to facilitate clamping between the clamping piece 31 and the shoulder strap 300. 【0043】 Referring to Figures 4 and 5, the positioning member 30 preferably further includes a closing member 32 provided at the open end of the recess 13. The closing member 32 is used to open and close the open end of the recess 13 and to reinforce the clamp between the clamp piece 31 and the shoulder strap 300. Specifically, the closing member 32 is one of a removable and cooperative fixing buckle and fixing hole, a buckle, a rope, or Velcro®. In this embodiment, the closing member 32 is selected as Velcro including a mother sticker 321 and a sub-sticker 322 provided on the opposing side walls of the recess 13. By attaching and detaching the mother sticker and sub-sticker, the recess 13 can be opened and closed easily and conveniently, which is easy to use and can effectively reduce manufacturing costs. 【0044】 Referring to Figures 4 and 5, the head protection device 100 of the present invention further includes a restricting member 40. The restricting member 40 is sewn to the protective piece 10 located below the positioning member 30 and has a restricting space for the shoulder strap 300 to pass through. By restraining the shoulder strap 300 wrapped around the protective piece 10, the restricting member 40 can not only further strengthen the connection between the protective piece 10 and the shoulder strap 300, but also restrict the direction of sliding of the shoulder strap 300, making the entire shoulder strap 300 more orderly. Specifically, the restricting member 40 is annular or semi-annular and has a certain elasticity. In this embodiment, both ends of a semi-annular restricting member 40 are sewn to the protective piece 10, forming a restricting space between the restricting member 40 and the protective piece 10 for the shoulder strap 300 to pass through, thereby reducing manufacturing costs. 【0045】 In relation to Figures 2, 5, and 6, when the head protection 100 of this embodiment is used in a child carrier 200 having a shoulder strap 300 of the first structure, the protective piece 10 as a whole detachably wraps around the adjustment buckle 400 and the outside of the adjustment portion 3021 and connecting portion 3022 of the upper shoulder strap 301 and lower shoulder strap 302 that are wrapped around the outside of the adjustment buckle 400. The upper shoulder strap 301, located between the relative intermediate upper end 600b of the backrest 600 and the adjustment buckle 400, is inserted into the recess 13 so that the clamp piece 31 is clamped to the back surface of the adjustment buckle 400 with the upper shoulder strap 301 wrapped around the adjustment buckle 400, and the clamp surface 311 of the upper shoulder strap 301 and the clamped clamp piece 31 becomes flat. Then, when the length of the shoulder strap 300 is adjusted by pulling the adjustment part 3021, the clamp piece 31 is always clamped to the upper shoulder strap 301, and the adjustment buckle 400 and the upper shoulder strap 301 wrapped around the adjustment buckle 400, as well as the adjustment part 3021 and connection part 3022 of the lower shoulder strap 302, are always encased in the protective piece 10, ensuring safe and comfortable use. When the closing member 32 is used in cooperation, the clamping effect is improved, and the usability is further enhanced when the adjustment part 3021 and connection part 3022 of the lower shoulder strap 302 on the adjustment buckle 400 pass through the restricting member 40. 【0046】 In relation to Figures 2, 5, and 7, when the head protection device 100 of this embodiment is used in an infant carrier 200 having a shoulder strap 300 of the first structure, the clamping positions of the clamp piece 31 and the upper shoulder strap 301 are different, and a different clamping method than the one shown in Figure 6 may be used. At this time, the upper shoulder strap 301, located between the lower connecting end 301b and the adjustment buckle 400, is inserted into the recess 13, and the clamp piece 31 is clamped to the upper shoulder strap 301 which is wrapped around the clamp end A of the adjustment buckle 400 at the relative front of the adjustment buckle 400. That is, the clamp piece 31 is clamped at a position between the upper shoulder strap 301 and the clamp end of the adjustment buckle 400a, and the clamp piece 31 is always clamped to the upper shoulder strap 301 by the adjustment buckle 400 so that the adjustment buckle 400, the upper shoulder strap 301 wrapped around the adjustment buckle 400, and the adjustment portion 3021 and connecting portion 3022 of the lower shoulder strap 302 are always enclosed in the protective piece 10, thus allowing for safe and comfortable use. In this embodiment, it is preferable that the clamp surface 311 of the clamp piece 31 be an inclined surface, which can effectively increase the robustness of the clamp. In this case, the clamp is more effective when the closing member 32 and / or the restricting member 40 are used in cooperation. 【0047】 In relation to Figures 3, 5, and 8, when the head protection device 100 of this embodiment is used in a child carrier 200 having a shoulder strap 300 of the second structure, unlike the clamping method shown in Figure 6, the clamp piece 31 is clamped to the opposite back surface of the adjustment buckle 400, the upper shoulder strap 301 is wound between the adjustment buckle 400 and the lower connecting end 301b, the clamp piece 31 specifically penetrates the through hole 3011, and the recess 13 is clamped to the upper shoulder strap 301 wound between the adjustment buckle 400 and the lower connecting end 301b, and the double clamp connection can more effectively enhance the robustness of the clamp connection. In this case, the clamping effect is further improved by using the closing member 32 and / or the restricting member 40 in combination. In a shoulder strap 300 with this configuration, the clamping method between the clamp piece 31 and the upper shoulder strap 301 is such that the clamp piece 31 is clamped to the upper shoulder strap 301 wound around the winding end A of the adjustment buckle 400a on the relative front of the adjustment buckle 400. In other words, the clamp piece 31 is clamped between the upper shoulder strap 301 and the winding end A of the adjustment buckle 400, and the upper shoulder strap 301, located at the winding end A on the relative front of the adjustment buckle 400 and the unwinding end on the rear opposite, is inserted correspondingly into the recess 13. As a result, the clamp piece 31 is always clamped to the upper shoulder strap 301 by the adjustment buckle 400, and the adjustment portion 3021 and connecting portion 3022 of the adjustment buckle 400, the upper shoulder strap 301, and the lower shoulder strap 302 are always enclosed in the protective piece 10, ensuring safe and comfortable use. 【0048】 Next, the configuration of the head protection device 100 according to the second embodiment of the present invention will be described with reference to Figures 9 to 11. 【0049】 The difference between this embodiment and the first embodiment is that the protective piece 10 is positioned in the lateral direction of the shoulder strap 300 and wraps only around the adjustment buckle 400 and the outside of the shoulder strap 300 wrapped around the adjustment buckle 400. In this embodiment, since the protective piece 10 is relatively short and mainly wraps around the outside of the adjustment buckle 400, it can wrap around the outside of the shoulder strap 300 for a short length, thus saving costs. Therefore, the recess 13 is positioned at the relative center of the relative left end or relative right end of the protective piece 10. The other components of the head protector 100 in this embodiment are basically the same as those of the head protector 100 in the first embodiment and are therefore omitted from this description. 【0050】 Next, the configuration of the head protection device 100 according to the third embodiment of the present invention will be described with reference to Figures 12 to 14. 【0051】 This embodiment differs from the first embodiment in that the positioning member 30 has a different structure, eliminating the need to provide a recess 13 in the protective piece 10 and eliminating the need to provide a closing member 32. In this embodiment, the positioning member 30 can clamp to the adjustment buckle 400 in the thickness direction of the shoulder strap 300. The positioning member 20 includes a hanger piece 33 provided on the protective piece 10. The hanger piece 33 is inserted into the adjustment buckle 400 and used to clamp to the adjustment buckle 400a. Specifically, the hanger piece 33 includes an assembly portion 331 and a clamp joint 332. One end of the assembly portion 331 is sewn to the protective piece 10, and the other end is sewn to the clamp joint 332. The clamp joint 332 passes through the opposite back surface of the adjustment buckle 400 (specifically, through the passage gap 401 between the upper shoulder strap 301 and the lower shoulder strap 302 wound around the adjustment buckle 400a) and reaches the opposite surface of the adjustment buckle 400, after which it can clamp to the adjustment buckle 400 along its longitudinal direction, thereby clamping to the adjustment buckle 400. It can be used more effectively if the adjustment portion 3021 and connecting portion 3022 of the lower shoulder strap 302 on the adjustment buckle 400 are arranged to pass through the regulating member 40. Specifically, the clamp joint 332 is T-shaped or ribbon-shaped. Preferably, a support member 333 is placed inside the clamp joint 332. The support member 333 has a certain hardness and elasticity to prevent the clamp joint 332 from separating from the adjustment buckle 400. Specifically, the support member 333 is selected as a piece of plastic. 【0052】 Refer to Figures 2 and 3 in conjunction with this. In this embodiment, whether the hanger piece 33 is sleeved to the shoulder strap 300 of the first structure or the shoulder strap 300 of the second structure, no matter how the shoulder strap 300 slides relative to the adjustment buckle 400, the hanger piece 33 is always clamped to the adjustment buckle 400, so that no relative sliding occurs between the protective piece 10 and the adjustment buckle 400, and the adjustment portion 3021 and connecting portion 3022 of the adjustment buckle 400 and the upper shoulder strap 301 wrapped around the adjustment buckle 400, as well as the lower shoulder strap 302, are always wrapped in the protective piece 10, making it safer and more comfortable to use. 【0053】 Next, the configuration of the head protection device 100 according to the fourth embodiment of the present invention will be described with reference to Figures 15 to 17. 【0054】 The main difference between this embodiment and the first embodiment lies in the structure of the positioning member 30. In this embodiment, the positioning member 30 can be clamped by the adjustment buckle 400 in the thickness direction of the shoulder strap 300, or by the shoulder strap 300 wrapped around the adjustment buckle 400 in the width direction of the shoulder strap 300, and specifically, it is clamped to the upper shoulder strap 301. Next, the positioning member 30 includes not only the clamp piece 31 but also, in the third embodiment, a hanger piece 33. In this case, by positioning the hanger piece 33 at the end of the recess 13, the strength of the clamp by double clamping between the protective piece 10 and the shoulder strap 300 and the adjustment buckle 400 can be further enhanced, and safety and comfort during use can be further improved. The specific clamp structure between the clamp piece 31 and the upper shoulder strap 301, and between the hanger piece 33 and the adjustment buckle 400 will be the same as in the first to third embodiments as appropriate, so a description will be omitted here. 【0055】 Compared to the prior art, the head protection device 100 of the present invention comprises a connecting member 20 and a positioning member 30 provided on a protective piece 10, and the protective piece 10 is detachably sleeved on the outside of an adjustment buckle 400 and the shoulder strap 300 wrapped around the adjustment buckle 400 via the connecting member 20. The shoulder strap 300 is connected between the backrest 600 and the seat body 500 of the infant carrier 200 and is adjustable in length. The positioning member 30 is clamped to the adjustment buckle 400, and / or the shoulder strap 300 is wound around the adjustment buckle 400a. In actual use, even if the infant collides with the protective piece 10 while sitting, or if the shoulder strap 300 slides against the adjustment buckle 400b when adjusting the length, the protective piece 10 is always clamped to the positioning member 30 and the adjustment buckle 400, and / or the shoulder strap 300 is wound around the adjustment buckle 400. This prevents relative sliding between the sleeve shoulder strap 300 and the adjustment buckle 400c, and the adjustment buckle 400 and the shoulder strap 300 wound around the adjustment buckle 400 are always enclosed within the protective piece 10. This effectively improves safety and comfort in use. The head protection device 100 of the present invention has a simple structure, is easy to use, is safe and reliable, and can effectively guarantee the safety and comfort of the head protection device 100 having an infant carrier 200. 【0056】 The embodiments disclosed above are merely preferred embodiments of the present invention and should not be used to limit the scope of the invention. Therefore, equivalent modifications under the claims of this application are still covered by the present invention.
