[0031] Example 1
[0032] Please see Figures 1 to 9 The present invention preferably provides the following technical solution: an ergonomic chair luggage box, comprising: a box body 111 and a seat back; the seat back includes an outer back panel 211 and an inner back panel, wherein the inner back panel includes at least one of a first back panel 212 and a second back panel 213, and the inner back panel is disposed inside the outer back panel 211 and is movably connected to the outer back panel 211, the outer back panel 211 is movably installed with the box body 111 and can overlap and fit together with the inner back panel and can be flipped and fastened to the box body 111.
[0033] The seat back provided in this application has an inner backrest that supports the waist and back. The inner backrest can be either a first backrest 212 or a second backrest 213. Figure 1 , 2 As shown in Figures 5 and 6, this function is to fully support the waist and back of infants and young children, prevent spinal curvature and deformation during travel, and promote the healthy growth of infants and young children.
[0034] The outer back panel 211, where the seat back is located, is movably installed at both ends with the body 111. Its inner side flips relative to the inner back panel. Therefore, when the seat back is needed, the outer back panel 211 can be made upright. When the seat back is not needed, the inner back panel can overlap with the outer back panel 211 and fold flat against the body 111 together with the outer back panel 211. This design does not occupy the internal storage space of the body 111, and the flat design with the body 111 does not affect the appearance, storage, boarding or check-in of the luggage.
[0035] The seat backrest of this application has a lumbar support function, which can fully support the waist and back of infants and young children. The outer backrest 211 where the seat backrest is located overlaps with the inner backrest and can be folded flat and attached to the suitcase 111 together with the inner backrest. This design does not occupy the internal storage space of the suitcase 111, and the flat attachment design with the suitcase 111 does not affect the appearance, storage, boarding or check-in of the suitcase.
[0036] Furthermore, the lower edge of the outer backrest 211 is flipped and connected to the lower edge of the second backrest 213, and the second backrest 213 can be flipped to cover the top surface of the box to become a seat cushion.
[0037] When the inner backrest is selected as the second backrest 213, it is combined Figure 1 As shown, the second backrest 213 folds forward and downward away from the outer backrest 211 and fits against the top of the box 111, thus realizing the process of the second backrest 213 being used as a seat cushion. Figure 9 As shown, this function is to improve the comfort of children when riding.
[0038] Example 2
[0039] As one embodiment of the inner backrest, a connector is provided between the outer backrest 211 and the second backrest 213. The connector includes at least one of a first connecting component and a second connecting component. The first connecting component includes a first fastener disposed between the upper edge of the outer backrest 211 and the upper edge of the second backrest 213 for adjusting the forward arch of the second backrest 213. The lower edge of the outer backrest 211 is flipped to connect with the lower edge of the second backrest 213. The second connecting component includes a second fastener disposed between the lower edge of the outer backrest 211 and the lower edge of the second backrest 213 and having the same structure as the first fastener. The upper edge of the outer backrest 211 is flipped to connect with the upper edge of the second backrest 213 for adjusting the forward arch of the second backrest 213.
[0040] Here, the connector can be either a first connecting assembly or a second connecting assembly. When the connector is preferably the first connecting assembly, the lower edge of the outer backing plate 211 is flipped and connected to the lower edge of the second backing plate 213, and a first fastener is provided on the other side of both. See details. Figure 2 , 3 As shown, when it is necessary to adjust the front arch of the second back plate 213, tighten the first fastener so that the upper edge of the second back plate 213 can be flipped and moved backward and downward.
[0041] When the connector is preferably the first connecting component, the same principle applies; simply move it in the opposite direction.
[0042] In this embodiment, by adjusting the forward arch of the second backrest 213, the waist and back of children of different ages can fit closely with the second backrest 213, ensuring the support effect of the second backrest 213.
[0043] Furthermore, the first fastener includes a connecting rope 513 fixed to the upper edge of the second back plate 213; and a through groove 511 opened in the middle of the outer back plate 211, wherein the through groove 511 is composed of rectangular grooves and circular grooves distributed and interconnected at the top and bottom; a plurality of limiting blocks 512 are longitudinally fixed on the back side of the outer back plate 211 corresponding to the rectangular groove where the through groove 511 is located; and also includes a limiting member 514 fixed to one end of the connecting rope 513 away from the second back plate 213, wherein the limiting member 514 is composed of a ring portion and a handle portion fixed to the outside of the ring portion, and the ring portion can engage with the corresponding limiting block 512.
[0044] Since the first and second fasteners have the same structure, we will take the first fastener as an example here, combined with... Figure 2 , 3 As shown, the connection between the outer backing plate 211 and the second backing plate 213 is at the lower edge, while the connecting rope 513 and the limiting member 514 fixed at the upper edge of the second backing plate 213 can pass through the through slot 511 opened on the outer backing plate 211 and extend to the back side of the outer backing plate 211. At the same time, several limiting blocks 512 are provided on the rectangular groove on the back side of the outer backing plate 211 corresponding to the through slot 511. Figure 1 , 2 As shown in Figures 3 and 4, when it is necessary to adjust the forward arch of the second backplate 213, the ring portion of the adjusting limit member 514 engages with the corresponding limiting block 512, as follows: Figure 2 , 3 As shown, during this process, the connecting rope 513 simultaneously pulls the upper edge of the second backrest 213 downwards and flips it over, so the second backrest 213 bends into an arch shape. At this time, the second backrest 213 in an arch shape can be used as a lumbar support. Conversely, when the limiting block 512 releases the limiting member 514, the second backrest 213 can spring back and return to a straight state.
[0045] Example 3
[0046] As another embodiment of the inner backing plate, the first backing plate 212 provided on the inner side of the outer backing plate 211 is fixed with sliders 313 at both ends; and slide grooves 312 are respectively opened on both sides of the outer backing plate 211. The slide grooves 312 are composed of vertical grooves and horizontal grooves that are distributed in front and back and connected to each other, and the two sliders 313 are respectively limited and slidably installed with the two slide grooves 312.
[0047] This combination Figure 5 , 6 As shown in Figures 7 and 8, as another embodiment of the seat back support for the lumbar and back, a first backrest 212 is provided on the inner side of the outer backrest 211, and sliders 313 respectively provided at both ends of the first backrest 212 can slide inside the grooves 312 respectively opened at both ends of the outer backrest 211. When the sliders 313 on the left and right sides are pushed to move inside the horizontal grooves where the grooves 312 are located, combined with Figure 6 , 8As shown, the first backrest 212 can be brought closer to the waist of the human body, and then the slider 313 can be pushed from the horizontal groove to the vertical groove to fix the first backrest 212 and support the waist of the human body.
[0048] Conversely, by pushing the slider 313 from the vertical groove into the horizontal groove, the first backing plate 212 can be pushed outward to fit against the inside of the backing plate 211 for storage.
[0049] Furthermore, the upper edge of the outer backrest 211 is turned towards the back to adapt to the human sitting posture, combined with Figure 2 As shown.
[0050] Furthermore, both the first backrest 212 and the second backrest 213 are composed of a frame and a sleeve outside the frame. The frame is made of elastic plastic sheet, plastic frame, or metal frame; the sleeve is made of soft material.
[0051] Both the first support plate 212 and the second support plate 213 here can be bent and spring back to their original shape;
[0052] The frame material can be selected from plastic sheets, plastic frames, or metal frames, while the body material can be selected from leather or mesh fabric to increase comfort.
[0053] Furthermore, magnetic sheets and magnets are respectively connected between the first back plate 212, the second back plate 213 and the outer back plate 211.
[0054] Here, magnetic sheets and magnets are connected between the first back plate 212 and the outer back plate 211, and between the second back plate 213 and the outer back plate 211, respectively, so that the first back plate 212 and the second back plate 213 can automatically fit into the inner side of the outer back plate 211 when not in use, making it convenient for the outer back plate 211 to be flipped, folded, and stored to cover the box 111.
[0055] Furthermore, a groove 311 is provided on the front side of the outer backing plate 211 to accommodate the inner backing plate.
[0056] This design improves the fit between the outer backrest 211 and the first backrest 212 or the second backrest 213, further enhancing the overlapping effect of the seat back. Figure 1 , 2 As shown in Figures 5 and 6, it is worth noting that the groove 311 can be designed according to the shape of the first support plate 212 or the second support plate 213.
[0057] Furthermore, the outer back plate 211 is provided with mounting holes 115 at both ends; and mounting shafts 112 are respectively provided on both sides of the housing 111, wherein the mounting shafts 112 are rotatably mounted with the corresponding mounting holes 115.
[0058] Combination Figure 1 , 2As shown in Figure 5, the two mounting shafts 112 on both sides of the housing 111 are installed one-to-one with the two mounting holes 115 at both ends of the outer back plate 211. When the inner back plate and the outer back plate 211 overlap and stick together, rotating the outer back plate 211 will cause the inner back plate and the outer back plate 211 to flip and connect to the housing 111.
