As used in the specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
[0049] refer to Figure 1 As shown, the present application discloses a box body 10, which includes a first shell 100 and a second shell 200 that can be opened and closed. The box body 10 also includes an axis 310, and the first shell 100 and the second shell 200 are linked by the axis 310 to achieve the opening and closing action.
[0050] In the present application, the box body 10 is an earphone box, which can be used to accommodate a Bluetooth headset and charge the Bluetooth headset therein. Of course, in other embodiments, the box body 10 can also be a cosmetic box, which can be used to accommodate cosmetics such as lipstick and air cushion. Alternatively, the box body 10 can also be a box structure for accommodating other portable objects.
[0051] In one design, the shaft 310 is usually fixed to the two sides or corners of the box body 10, and fixed to the second shell 200 or the side wall of the box body 10. The shaft 310 is usually made of metal or plastic material, and has a certain elasticity and durability. Figure 1As shown, the first shell 100 of the box body 10 usually has corresponding grooves or fixing points for mounting the connecting part of the shaft body 310. These designs can ensure that the first shell 100 is firmly connected to the shaft body 310 and remains stable during the opening and closing process. The second shell 200 of the box body 10 also usually has a structural protrusion corresponding to the first shell 100 to accommodate the connecting part of the shaft body 310 and ensure smooth linkage between the first shell 100 and the second shell 200. The user gently presses or pulls up the second shell 200 of the box body 10, and the shaft body 310 rotates the second shell 200 relative to the first shell 100, thereby completing the opening action of the box body 10. When the box body 10 is not needed, the user can simply press the second shell 200, and the shaft body 310 aligns the second shell 200 with the first shell 100 again to complete the closing action of the box body 10.
[0052] The above-mentioned box body 10 is usually located at the two sides, corners or on the protrusion of the first shell 100 because the shaft body 310 is usually located at the two sides, corners or on the protrusion of the first shell 100. Figure 1 As shown, on the one hand, this design is not aesthetically pleasing because the protrusions and recesses matched with the shaft 310 are exposed to the outside. On the other hand, when the box body 10 is impacted (for example, the box body falls to the ground), the shaft 310 is easily damaged, thereby making it impossible for the first shell 100 and the second shell 200 to rotate relative to each other.
[0053] In order to solve the above problems, the applicant has improved the structure of the box body 10. Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the box body 10 includes a first shell 100, a second shell 200 and a rotating shaft mechanism 300. The first shell 100 and the second shell 200 are rotatably connected via the rotating shaft mechanism 300.
[0054] The first shell 100 has an accommodating space 400 inside, and the accommodating space 400 has an opening 410 ; one end of the rotating shaft mechanism 300 is located in the accommodating space 400 and is rotatably connected to the first shell 100 ; the other end of the rotating shaft mechanism 300 extends out of the accommodating space 400 through the opening 410 and is fixed to the second shell 200 .
[0055] refer to Figure 4 and Figure 5 As shown, the box body 10 can be switched between an open cover state A1 and a closed cover state A2.
[0056] When the box body 10 is in the closed state A2, the hinge mechanism 300 is located in the space surrounded by the first shell 100 and the second shell 200. At this time, the hinge mechanism 300 is arranged in the accommodation space 400 to prevent any structure thereof from being exposed outside the box body 10, and the user cannot observe the hinge mechanism 300 outside the box body 10. When the box body 10 is impacted in this state, since the hinge mechanism 300 is located in the internal accommodation space 400, it will be protected by the first shell 100, thereby preventing the hinge mechanism 300 from being damaged, and thus making the hinge mechanism 300 and the box body 10 as a whole have better stability.
[0057] When the box body 10 switches from the closed state A2 to the open state A1, the end of the hinge mechanism 300 connected to the second shell 200 moves away from the opening 410. In the above arrangement, due to the presence of the opening 410, the hinge mechanism 300 can freely enter and exit the accommodation space, thereby achieving a smooth opening and closing action.
[0058] Based on the above configuration, since the rotating shaft mechanism 300 is disposed in the accommodation space 400, there is no need to provide a groove on the first shell 100 and a corresponding structural protrusion on the second shell 200. Figure 3 As shown, in the closed state A2, no structure of the rotating shaft mechanism 300 can be seen from the outside, thereby improving the overall aesthetics of the box body 10. Figure 4 , Figure 5 As shown, when the box body 10 is in the open cover state A1, although the hinge mechanism 300 is partially arranged outside the accommodating space 400 through the opening 410, the user usually directly holds it with his hands at this time, so it is not easy to collide and fall. When the box body 10 is in the closed cover state A2, the hinge mechanism 300 is arranged in the accommodating space 400, and the box body 10 is in the desktop, pocket or bag in the closed cover state A2. When the desktop is hit or something is taken out from the pocket / bag, the box body 10 will fall. Because the box body 10 is in the closed cover state A2 when falling, the hinge mechanism 300 is arranged in the accommodating space 400, so when it is impacted, the hinge mechanism 300 will be protected by the first shell 100, thereby avoiding the hinge mechanism 300 from being damaged, thereby obtaining better durability.
[0059] In this embodiment, reference Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the above-mentioned rotating shaft mechanism 300 includes a shaft body 310 and a connecting member 320. The shaft body 310 is arranged in the accommodating space 400 and is rotatably connected to the first shell 100. One end of the connecting member 320 is connected to the shaft body 310, and the other end of the connecting member 320 passes through the opening 410 and is connected to the inside of the second shell 200; wherein, the connecting member 320 at least includes an arc segment 321. When the box body 10 is in the closed state A2, the arc segment 321 is located in the accommodating space 400, and when the box body 10 is in the open state A1, the arc segment 321 is located outside the accommodating space 400.
[0060] It should be noted that the number of shafts can be one or more, and this application does not limit it. The arc segment 321 does not have to be an arc, and can also be an arc-shaped body connected by multiple line segments. As long as it can rotate with the second shell 200 and does not interfere with the first shell 100 and the second shell 200, it should fall within the protection scope of this application. Figure 6 , Figure 7 As shown, the angle α formed by the two ends of the arc segment 321 pointing to the center is greater than or equal to 90° and less than or equal to 150°. For example, it can be 90°, 100°, 110°, 120°, 130°, 140°, 150°. The designer can select different angles α according to the different rotation angles of the box body 10.
[0061] In this embodiment, an arc segment 321 is provided, and the arc segment 321 matches the relative rotation angle of the first shell 100 and the second shell 200, so that the conversion from the closed cover state A2 to the open cover state A1 is smoother, and because the arc segment 321 matches the relative rotation angle of the first shell 100 and the second shell 200, so that the rotation path thereof is fixed, the opening 410 can be set as small as possible, thereby minimizing the exposure of the rotating shaft mechanism 300 to the outside, and while being aesthetically pleasing, it can also minimize or prevent foreign impurities from entering the accommodation space 400 through the opening 410. At the same time, in the process of switching the box body 10 from the closed cover state A2 to the open cover state A1, and when the box body 10 is in the open cover state A1, the arc segment 321 covers most of the position of the opening 410, which can also minimize or prevent foreign impurities from entering the accommodation space 400 through the opening 410.
[0062] In this embodiment, reference Figure 5 and Figure 8As shown, the connecting member 320 also includes a connecting section 322, the connecting section 322 is connected between the shaft body 310 and the arc section 321, and a limiting protrusion 340 is provided at the connection between the connecting section 322 and the arc section 321, and the first shell 100 is provided with a limiting rib 350. When the box body 10 rotates from the closed cover state A2 to the open cover state A1, the limiting protrusion 340 and the limiting rib 350 conflict with each other to limit further rotation. It should be noted that the length of the connecting section 322 can be set to be greater than or equal to 5mm and less than or equal to 15mm. Within this range, on the one hand, the rotation of the connecting member 320 can be well guaranteed, and at the same time, it will not take up too much space. For example, the length of the connecting section 322 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm.
[0063] Based on the above configuration, because there are the limiting protrusion 340 and the limiting rib 350, after the cover-opening state A1 is reached, the connecting member 320 will not be separated from the accommodating space 400 due to inertia, which will cause the box body 10 to be unable to turn back from the cover-opening state A1 to the cover-closing state A2, thereby making the box body 10 stably operate in the cover-closing state A2 and the cover-opening state A1, thereby enhancing stability. At the same time, when the box body 10 is in the cover-opening state A1, the limiting rib 350 abuts against the limiting protrusion 340 to limit foreign matter from entering the accommodating space 400 through the portion of the opening 410 close to the limiting rib 350. The arc segment 321 is closed at other positions of the opening, thereby limiting foreign matter from entering the accommodating space 400 through the middle of the opening 410 and the portion of the opening 410 close to the rear wall.
[0064] At the same time, the limiting rib 350 can be set as a protruding structure, so that when the box body 10 switches from the open cover state A1 to the closed cover state A2, the limiting rib 350 can abut against the arc segment 321, or the gap between the limiting rib 350 and the arc segment 321 can be reduced as much as possible, thereby minimizing the entry of foreign impurities into the accommodating space 400 through the opening 410, thereby improving the stability and service life of the hinge mechanism 300.
[0065] Further, in this embodiment, reference Figure 4 , Figure 5 , Figure 6 as well as Figure 7As shown, the hinge mechanism 300 includes an elastic member 330, and the elastic member 330 is arranged in the accommodating space 400, and the elastic member 330 is connected to the first shell 100. When the box body 10 is in the closed state A2, the elastic member 330 is in a compressed state to limit the box body 10 from switching from the closed state A2 to the open state A1. When the box body 10 is in the open state A1, the elastic member 330 may always be in a compressed state or in a state without pressure / tension. Among them, the length of the elastic member 330 in the closed state A2 is less than the length of the elastic member 330 in the open state A1, so as to ensure that the elastic potential energy of the elastic member 330 in the open state A1 is less than the elastic potential energy of the elastic member 330 in the closed state A2. It should be noted that, referring to Figure 8 , Fig. 9 , Fig.10 as well as Fig.11 As shown, the elastic member 330 provided here may be a double helical butterfly spring. Since the double helical butterfly spring has two elastic parts and is evenly distributed in the accommodation space 400, it can provide a more stable elastic potential energy for the opening and closing of the box body 10, thereby making the opening and closing process of the box body 10 more stable. Fig.12 and Fig.13 As shown, the elastic member 330 provided here may also be a Z-shaped spring, which is compressed by its upper end and lower end being close to each other, and stretched by its upper end and lower end being away from each other. In addition, the Z-shaped spring is provided with two annular rings at the turning point, so that the compression of the spring is more stable, which can provide more stable elastic potential energy for the opening and closing of the box body 10, thereby making the opening and closing process of the box body 10 more stable.
[0066] Since the elastic member 330 is in a compressed state to limit the conversion of the box body 10 from the closed state A2 to the open state A1, when the box body 10 is in the closed state A2, the first shell 100 and the second shell 200 will not be opened due to a small external force. For example, when the box body 10 in the closed state A2 is placed in a pocket or a backpack, the first shell 100 and the second shell 200 will not be opened due to the shaking of walking, so that the items in the box body 10 can be prevented from escaping from the space in the box body 10. At the same time, in this embodiment, when the box body 10 is in the open state A1, the elastic potential energy of the elastic member 330 is almost zero. Through the above arrangement, the box body 10 is limited to convert from the open state A1 to the closed state A2. Specifically, when the box body 10 is in the open state A1, the relative position relationship between the first shell 100 and the second shell 200 will not be changed due to a small external force, so that the box body 10 can be relatively stably in the open state A1.
[0067] In this embodiment, reference Figure 4-Figure 11As shown, the connecting segment 322 and the arc segment 321 have a connecting end 360 , one end of the elastic member 330 is disposed at the connecting end 360 , and the other end of the elastic member 330 is connected to the first shell 100 .
[0068] In this design, the elastic member 330 is located at the outermost end of the connecting section 322, so the elastic member 330 can be compressed to the shortest in the closed state A2, so that the elastic member 330 provides a greater force, thereby making the items in the box body 10 safer.
[0069] It should also be noted that the reference Figure 4 , Figure 5 , Figure 8 as well as Fig. 9 As shown, the connecting end 360 is provided with a mounting hole 361 , the first shell portion 100 is provided with a snap-in groove 370 , the elastic member 330 includes a mounting portion 331 , an elastic portion 332 and a snap-in portion 333 which are connected in sequence, the mounting portion 331 is provided in the mounting hole 361 , and the snap-in portion 333 is provided in the snap-in groove 370 .
[0070] During installation, it is only necessary to clamp the clamping portion 333 in the clamping groove 370 and pass the mounting portion 331 through the mounting hole 361 , so that the elastic member 330 can be assembled and the effect can be achieved. The process is simple and convenient.
[0071] In this embodiment, reference Figure 6 , Figure 7 As shown, the connector 320 may also be provided with a fixed section 323, the fixed section 323 is provided at one end of the connecting section 322 of the arc section 321, and the fixed section 323 is fixedly connected to the second shell 200, and the angle β between the fixed section 323 and the tangent of the connection point of the arc section 321 is greater than or equal to 75°, and less than or equal to 105°. For example, the angle β between the fixed section 323 and the tangent of the connection point of the arc section 321 can be 75°, 80°, 85°, 90°, 95°, 100°, 105°. Within this angle range, the first shell 100 and the second shell 200 can be well matched, and it is convenient to match and fix with the second shell 200.
[0072] like Figure 4 As shown, in this embodiment, the second shell 200 includes an outer shell unit 210 and an inner shell unit 220. The outer shell unit 210 and the inner shell unit 220 are fitted and fixed, and the fixing section 323 is fixed in the gap between the outer shell unit 210 and the inner shell unit 220 to achieve a fixed connection between the fixing section 323 and the second shell 200, so that the rotating shaft mechanism 300 can move with the movement of the second shell 200.
[0073] In addition, refer to Figure 4 , Figure 5 , Figure 8 as well as Fig. 9 As shown, the first shell portion 100 in the earphone box using the above-mentioned hinge mechanism 300 includes a first wall 110 and a second wall 120. At least part of the structure of the first wall 110 is exposed and serves as the outer surface of the first shell portion 100. In this embodiment, when the earphone box is in the closed state A2, the entire structure of the second wall 120 is located inside the earphone box. Of course, in other embodiments, when the earphone box is in the closed state A2, part of the structure of the second wall 120 is exposed to serve as the outer surface of the first shell portion 100. At least part of the structure of the second wall 120 is recessed inwardly and forms a working space 121 for accommodating earphones. At the same time, the first wall 110 and the second wall 120 enclose the above-mentioned accommodating space 400. In addition, one end of the second wall 120 close to the inner shell unit 220 is spaced apart from the first wall 110 to form the above-mentioned opening 410. Through the above arrangement, the second wall 120 forming the working space 121 can be directly utilized to form the accommodating space 400, which maximizes the use of the structure of the earphone box itself. Such an arrangement can save space, make the space utilization of the earphone box more reasonable, obtain a better spatial layout, and save costs at the same time.
