[0048] The present invention provides a storage box 100 .

[0049] Please refer to Figures 1 to 5 In one embodiment of the storage box 100 of the present application, the storage box 100 includes a box body 10 and a connecting structure 30, wherein the box body 10 includes a first box body 11 and a second box body 13 covering each other; the connecting structure 30 is arranged on the inner side of the box body 10, and is respectively connected to the first box body 11 and the second box body 13, and one side edge of the first box body 11 and the second box body 13 is spaced apart and rotatably connected.

[0050] The storage box 100 proposed in the present application can be used for storing products such as glasses or electronic devices, and includes a box body 10 formed by a first box body 11 and a second box body 13 that cover each other, and a connecting structure 30 for connecting the first box body 11 and the second box body 13. An installation space is formed in the box body 10, and the connecting structure 30 is arranged in the installation space and is connected to the first box body 11 and the second box body 13 respectively, so that the first box body 11 can be rotated relative to the second box body 13 to open and close. When the first box body 11 is flipped open and closed relative to the second box body 13, the first box body 11 and the second box body 13 are connected by the connecting structure 30 to prevent parts from being scattered and easily lost. The connecting structure 30 is arranged on the inside of the box body, so that when the box body 10 is closed, the connecting structure 30 is hidden inside the box body 10 to prevent the connecting structure 30 from being exposed and easily damaged, and the outer surfaces of the first box body 11 and the second box body 13 are continuously connected to maintain the integrity of the appearance of the storage box 100.

[0051] Among them, the connecting structure 30 is used to make the first box body 11 and the second box body 13 located on one of the sides on the same side rotatably connected; and the sides where the first box body 11 and the second box body 13 are rotatably connected are arranged at intervals, so that during the rotation of the second box body 13 relative to the first box body 11, the end edge of the second box body 13 facing the first box body 11 will not be blocked or interfered by the open end surface of the first box body 11, further avoiding mutual interference between the second box body 13 and the first box body 11 during the rotation opening and closing process, thereby improving the performance stability of the storage box 100; the rotating structure can be the rotating shaft 31 or the connecting rod 335 structure in the following embodiments, etc., which are not limited here.

[0052] Therefore, it can be understood that the technical solution of the present invention, by placing the connecting structure 30 on the inner side of the box body 10, is respectively connected to the first box body 11 and the second box body 13 in the box body 10, and the side intervals of the rotationally connected first box body 11 and second box body 13 are arranged, so that the second box body 13 can be rotated and opened relative to the first box body 11, thereby avoiding that the end face edge of the second box body 13 facing the first box body 11 will not be blocked or interfered by the open end face of the first box body 11 during the process of the second box body 13 being rotated and opened relative to the first box body 11, and the connecting structure 30 can be hidden when the box body 10 is closed to avoid exposure of the connecting structure 30, so that the outer side walls of the first box body 11 and the second box body 13 are continuously connected, thereby ensuring the integrity of the appearance of the storage box 100 and reducing the risk of damage to the connecting structure 30.

[0053] Please refer to Figure 5 In some embodiments of the present application, the connecting structure 30 includes a rotating shaft 31, which is arranged at the opening edge of the first box body 11 and is spaced apart from the opening edge of the first box body 11. The second box body 13 is rotatably connected to the rotating shaft 31 and is spaced apart from the first box body 11 on the side where the rotating shaft 31 is located.

[0054] In this embodiment, the connection structure 30 also includes a rotating shaft 31, which is arranged at the opening edge of the first box body 11 and is spaced apart from the first box body 11. In this way, when the second box body 13 is rotatably connected with the rotating shaft 31, the second box body 13 is spaced apart from the first box body 11 on the side where the rotating shaft 31 is located, that is, the second box body 13 is supported by the rotating shaft 31, so that when the second box body 13 rotates relative to the first box body 11, the second box body 13 and the first box body 11 will not interfere with each other; in addition, the second box body 13 is rotated around the rotating shaft 31, and the rotating shaft 31 is used to guide and limit the second box body 13, so as to improve the position stability of the second box body 13 during the rotation process. In this embodiment, one end of the damping shaft 333 can be rotatably connected with the rotating shaft 31, or it can be eccentrically arranged with the rotating shaft 31 as in the following embodiment, which is not limited here.

[0055] In addition, in this embodiment, a hinged portion may be provided on the end surface of the second box body 13 facing the first box body 11 for rotationally connecting with the rotating shaft 31, or a rotation groove 135 may be provided on the inner wall of the second box body 13 for accommodating the rotating shaft 31 in the following embodiment, which is not limited here.

[0056] Please refer to Figure 5 and Figure 6 In some embodiments of the present application, a rotation groove 135 is formed on the inner wall of the second box body 13, and the rotation shaft 31 is rotatably disposed in the rotation groove 135, and the two ends of the rotation shaft 31 are rotatably connected to the two end groove walls of the rotation groove 135 respectively;

[0057] During the process of the second box body 13 rotating to open and close, the groove wall of the rotating groove 135 moves in and out between the rotating shaft 31 and the first box body 11 .

[0058] In this embodiment, a rotation groove 135 extending along the length direction of the rotation shaft 31 is provided on the inner wall of the second box body 13, and the rotation shaft 31 is arranged in the rotation groove 135, and the two ends of the rotation shaft 31 are respectively rotatably inserted in the two end groove walls of the rotation groove 135, so that the second box body 13 is rotatably connected with the rotation shaft 31. In this way, when the second box body 13 is closed relative to the first box body 11, since the rotation shaft 31 is hidden in the rotation groove 135 and is blocked by the inner wall of the first box body 11, the storage box 13 can be opened and closed. When observing from the outside of the storage box 100 into the gap between the first box body 11 and the second box body 13 at the side where the shaft 31 is located, the shaft 31 cannot be seen, thereby achieving the purpose of hiding the shaft 31; and when the second box body 13 is rotated and opened relative to the first box body 11, part of the groove wall of the rotating groove 135 can enter the gap between the shaft 31 and the opening edge of the first box body 11, and will not interfere with the shaft 31, thereby increasing the angle at which the second box body 13 can be opened relative to the first box body 11.

[0059] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, a fixing portion 311 is provided on a side wall of the rotating shaft 31 , and the fixing portion 311 is connected to the first box body 11 so that the rotating shaft 31 is spaced apart from an opening edge of the first box body 11 .

[0060] In this embodiment, the fixing portion 311 is used to support the rotating shaft 31 so that the rotating shaft 31 and the opening edge of the first box body 11 are spaced apart, wherein the fixing portion 311 can be arranged on the side wall of the rotating shaft 31 facing the first box body 11, and is located at the end of the rotating shaft 31, so as to be clamped between the opening of the first box body 11 and the rotating shaft 31, thereby supporting the rotating shaft 31, and two fixing portions 311 can be respectively arranged at both ends of the rotating shaft 31, so that the connection between the rotating shaft 31 and the first box body 11 is more stable, and an avoidance space is still formed between the rotating shaft 31 and the opening edge of the first box body 11 between the two fixing portions 311 for avoiding the second box body 13; at this time, the fixing portion 311 can be integrally formed with the rotating shaft 31 and the first box body 11, or it can be detachably connected between any two of them; the fixing portion 311 can also be a structural form set as the first connecting section 3111 and the second connecting section 3113 in the following embodiment, which will not be repeated here.

[0061] Please refer to Figure 2 In some embodiments of the present application, the fixing portion 311 includes a first connecting segment 3111 and a second connecting segment 3113, wherein the first connecting segment 3111 extends from the opening edge of the first box body 11 to the inner side of the opening of the first box body 11, and the second connecting segment 3113 extends from the end of the first connecting segment 3111 to the inside of the first box body 11 and is connected to the first box body 11.

[0062] In this embodiment, the fixing portion 311 includes at least a first connecting section 3111 and a second connecting section 3113 connected to each other. The first connecting section 3111 extends from the side wall of the rotating shaft 31 to the inner side of the opening of the first box body 11, and the second connecting section 3113 extends from the first connecting section 3111 to the internal space of the first box body 11 and is arranged opposite to the inner side wall of the first box body 11, so that the second connecting section 3113 is connected to the inner side wall of the first box body 11. In this way, the fixing portion 311 is arranged on the inner side of the rotating shaft 31, so that the rotating shaft 31 and the opening edge of the first box body 11 are completely spaced apart and there are no obstacles, so as to avoid the setting of the fixing portion 311 causing the fixing portion 311 to interfere with the second box body 13 when the second box body 13 is opened, thereby affecting the opening range of the second box body 13. Among them, the connection method between the second connecting section 3113 and the inner wall of the first box body 11 can be bonding, bolting, riveting, snap-on connection, plug-in, welding, etc., which is not limited here. It is also possible that other connecting sections are extended from the end of the second connecting section 3113 away from the first connecting section 3111, so that the fixing part 311 can flexibly choose the connection method and connection position with the first box body 11.

[0063] Please refer to Figure 2 and Figure 6In some embodiments of the present application, the connection structure 30 includes a damping structure 33, which is respectively connected to the second box body 13 and the first box body 11, and generates a damping force when the second box body 13 is flipped relative to the first box body 11.

[0064] In this embodiment, the connection structure 30 further includes a damping structure 33, which can generate a damping force during the flipping process of the second box body 13 relative to the first box body 11, so that the user can clearly feel the rotation effect. At the same time, when the second box body 13 is opened or closed relative to the first box body 11 to a desired state, the second box body 13 and the first box body 11 can be prevented from rotating relative to each other without external force, so that the second box body 13 and the first box body 11 can stably maintain the current state; thereby, the second box body 13 can be prevented from suddenly closing and pinching the user when the storage box 100 needs to be taken out of the storage box 100, and the second box body 13 can be prevented from opening when the storage box 100 is closed, causing the items in the storage box 100 to fall out. The damping structure 33 can be arranged between the rotating shaft 31 and the second box body 13 in the above embodiment, so that the rotating shaft 31 and the second box body 13 are tightly matched or adopt a ratchet structure, etc., or it can be a damping shaft 333 and a sleeve 331 that are eccentrically arranged with the rotating shaft 31 in the following embodiment, which is not limited here.

[0065] Please refer to Figure 5 In some embodiments of the present application, the damping structure 33 includes a sleeve 331 and a damping shaft 333, and the sleeve 331 is sleeved on the outer side of the damping shaft 333 and connected to the inner wall of the first box body 11;

[0066] The second box body 13 is in transmission connection with the damping shaft 333 , and drives the damping shaft 333 to rotate relative to the shaft sleeve 331 and generate a damping force during the process of rotating and opening relative to the first box body 11 .

[0067] In this embodiment, the damping structure 33 includes a sleeve 331 arranged on the inner wall of the first box body 11, so that the damping shaft 333 is inserted into the sleeve 331, and when the second box body 13 is opened and closed relative to the first box body 11, the damping shaft 333 can drive the damping shaft 333 to rotate relative to the sleeve 331. Such a configuration increases the connection area and connection strength between the damping shaft 333 and the first box body 11, prevents the damping shaft 333 from escaping from the first box body 11, thereby improving the stability of the damping shaft 333 relative to the first box body 11. The connection between the first box body 11 and the second box body 13 is more stable. The user can clearly feel the rotation effect. At the same time, when the second box body 13 is opened or closed to the desired state relative to the first box body 11, the damping shaft 333 and the sleeve 331 can be prevented from rotating relative to each other without external force, so that the second box body 13 and the first box body 11 can stably maintain the current state, and the second box body 13 can be prevented from rotating freely relative to the first box body 11; thereby, the second box body 13 can be prevented from suddenly closing and pinching the user when it is necessary to take or put items from the storage box 100, and the second box body 13 can be prevented from opening when the storage box 100 is closed, causing the items in the storage box 100 to fall out.

[0068] In some embodiments, the damping shaft 333 may be the rotating shaft 31 of the aforementioned embodiment, that is, the rotating shaft 31 is reused as the damping shaft 333 or the damping shaft 333 is coaxially arranged with the rotating shaft 31, so that a damping force is generated at the rotation connection position during the rotation of the second box body 13 around the rotating shaft 31. The damping shaft 333 may also be eccentrically arranged with the rotating shaft 31 in the following embodiments.

[0069] Please refer to Figure 5 In some embodiments of the present application, the damping shaft 333 and the second box body 13 are eccentrically arranged relative to the rotation axis of the first box body 11.

[0070] In this embodiment, the damping shaft 333 is eccentrically arranged with respect to the rotation axis of the second box body 13, so that there are at least two connection fulcrums between the second box body 13 and the first box body 11, thereby improving the connection strength between the first box body 11 and the second box body 13. When the damping shaft 333 is eccentrically arranged with respect to the rotation axis 31, the second box body 13 can drive the damping shaft 333 to rotate relative to the shaft sleeve 331 through the matching structure of the connecting rod 335 and the crankshaft 337 in the following embodiment, or as shown in the accompanying drawings. Figures 11 to 14As shown, one end of the connecting rod 335 away from the damping shaft 333 can be slidably disposed on the inner wall of the second box body 13. For example, a limit member 338 can be set on the inner wall of the second box body 13, and a slide groove 3381 is provided, so that one end of the connecting member can be slidably disposed in the slide groove 3381. In this way, when the second box body 13 is rotated and opened and closed relative to the first box body 11, the second box body 13 drives the connecting member to rotate relative to the first box body 11, and makes one end of the connecting member slide along the slide groove 3381, thereby adjusting the relative position of the connecting member and the second box body 13, avoiding that the connecting structure 30 locks the second box body 13 and causes interference between the first box body 11 and the second box body 13.

[0071] Please refer to Figures 1 to 4 In some embodiments of the present application, the damping structure 33 also includes a connecting rod 335 and a crankshaft 337, one end of the connecting rod 335 is connected to the damping shaft 333, the other end of the connecting rod 335 is rotatably connected to the crankshaft 337, and the end of the crankshaft 337 away from the connecting rod 335 is rotatably connected to the inner wall of the second box body 13.

[0072] In this embodiment, the second box body 13 is connected to the damping shaft 333 through the transmission structure of the crankshaft 337 and the connecting rod 335, so that the damping shaft 333 is driven to rotate relative to the sleeve 331 during the rotation and opening and closing of the second box body 13, wherein the crankshaft 337 can be a rod-shaped or a swing arm structure in the following embodiment, which is not limited here, so that one end of the crankshaft 337 is rotationally connected to the inner wall of the second box body 13, and the other end is rotationally connected to the connecting rod 335, and the end of the connecting rod 335 away from the crankshaft 337 is connected to the damping shaft 333. At this time, when the second box body 13 rotates, the connecting rod 335 will be driven to rotate through the crankshaft 337, and the connecting rod 335 will also drive the damping shaft 333 to rotate relative to the sleeve 331 to generate a damping force. It can be understood that at this time, the end of the crankshaft 337 connected to the second box body 13 is used as the main axis of the crankshaft 337, and the end of the crankshaft 337 connected to the connecting rod 335 is used as the secondary axis of the crankshaft 337. The distance between the main axis 3375 of the crankshaft and the rotating shaft 31 of the second box body 13 remains unchanged, the distance between the secondary axis 3377 of the crankshaft and the damping shaft 333 remains unchanged, and the distance between the rotating shaft 31 and the damping shaft 333 also remains unchanged, so that a four-link 335 mechanism is formed between the crankshaft 337, the connecting rod 335, the damping shaft 333 and the rotating shaft 31, so that the first box body 11 and the second box body 13 can maintain structural stability in any state through the mechanism without external force. For details, refer to Fig.10The axis of the rotating shaft 31 is restricted and fixed in the X and Y directions, and the rotational freedom in the Z direction is released (that is, the rotating shaft 31 can only rotate in the Z direction and cannot move); the axis of the damping shaft 333 is restricted and fixed in the X and Y directions, and the damping shaft 333 is subject to the friction between the damping shaft 333 and the sleeve 331, and an external force is required to rotate in the Z direction (it can rotate in the Z direction under the action of an external force, but cannot move); the crankshaft main The axis 3375 is fixed on the second box body 13 and can rotate along its own Z direction, and can rotate around the rotating shaft 31 together with the second box body 13; the axis of the rotating shaft 31 and the axis of the damping shaft 333, the axis of the damping shaft 333 and the main axis 3375 of the crankshaft, the main axis 3375 of the crankshaft and the secondary axis 3377 of the crankshaft, and the secondary axis 3377 of the crankshaft and the axis of the rotating shaft 31 are all connected by arms. Under the action of external force, the axis of the damping shaft 333 is opened When it reaches angle A, when there is no external force, the interference fit between the damping shaft 333 and the sleeve 331 and the connecting rod 335 generates friction, and it cannot rotate. The axis center of the rotating shaft 31, the axis center of the damping shaft 333 and the crankshaft secondary axis 3377 form a triangular area, which becomes a stable supporting surface. At this time, the virtual arm between the axis center of the rotating shaft 31 and the crankshaft secondary axis 3377 cannot move. Because the arm lengths between the axis center of the rotating shaft 31 and the crankshaft secondary axis 3377, and between the crankshaft secondary axis 3377 and the crankshaft main axis 3375 are fixed, the crankshaft secondary axis 3377, the crankshaft main axis 3375 and the axis center of the rotating shaft 31 form another triangular area, which becomes another stable supporting surface, so that the four axes can be fixed without external force, so that the first box body 11 and the second box body 13 can maintain structural stability in any opening and closing state and angle through this mechanism without external force.

[0073] Please refer to Figures 4 to 7 In some embodiments of the present application, two connecting seats 137 are protruded from the inner wall of the second box body 13, the crankshaft 337 includes a cross bar 3371 and two rotating parts 3373 located at both ends of the cross bar 3371 and arranged at an angle to the cross bar 3371, one end of the rotating part 3373 away from the cross bar 3371 is rotatably connected to one of the connecting seats 137, and one end of the connecting rod 335 is sleeved on the cross bar 3371 and rotatably connected to the cross bar 3371.

[0074] In this embodiment, the crankshaft 337 includes a cross bar 3371 and two rotating parts 3373 located at both ends of the cross bar 3371. The rotating part 3373 extends outward from the cross bar 3371 along the radial direction of the cross bar 3371, and the end of the rotating part 3373 away from the cross bar 3371 can be rotatably connected to the connecting seat 137 provided on the inner wall of the second box body 13. The rotating shaft can be provided to penetrate the rotating part 3373 and the connecting seat 137, or the rotating part 3373 away from the cross bar can be provided as shown in the figure. One end of 3371 extends a connecting arm toward one side of the connecting seat 137 and is rotatably connected to the connecting seat 137. By so configuring, the crankshaft 337 is limited between the two connecting seats 137, thereby improving the connection strength between the crankshaft 337 and the second box body 13. By configuring the cross bar 3371, the connection area between the connecting rod 335 and the crankshaft 337 can be increased, or at least two connecting rods 335 can be arranged side by side along the length direction of the cross bar 3371, thereby improving the connection strength and the stability of the transmission process.

[0075] Please refer to Figure 8 and Fig. 9 In some embodiments of the present application, a limiting groove 3313 is provided on the side wall of the sleeve 331, and the limiting groove 3313 extends along a portion of the circumference of the sleeve 331. A stopper 3351 is convexly provided on the side edge of the damping shaft 333. The stopper 3351 is disposed in the limiting groove 3313 and slides along the limiting groove 3313 when the damping shaft 333 rotates, so as to limit the rotation angle of the damping shaft 333 driven by the damping shaft 333 relative to the sleeve 331.

[0076] In this embodiment, a limiting groove 3313 is provided on the sleeve 331, and a stopper 3351 cooperating with the limiting groove 3313 is provided on the damping shaft 333. The stopper 3351 can slide along the limiting groove 3313 in the circumferential direction of the sleeve 331 during the rotation of the damping shaft 333 relative to the sleeve 331, and abut against the groove walls at both ends of the limiting groove 3313 when the second box body 13 is opened or closed, so as to limit the rotatable angle of the damping shaft 333 driving the damping shaft 333 to rotate relative to the sleeve 331, so as to prevent the damping shaft 333 and the connecting rod from continuing to rotate when the second box body 13 is opened or closed, so that the first box body 11 and the second box body 13 can maintain the stability of the current state.

[0077] Please refer to Figure 7 and Figure 8 In some embodiments of the present application, a side wall of the sleeve 331 is provided with an avoidance groove 3311 , a portion of the damping shaft 333 is exposed in the avoidance groove 3311 , and one end of the connecting rod 335 is disposed in the avoidance groove 3311 and connected to the damping shaft 333 .

[0078] In this embodiment, a side wall of the sleeve 331 is provided with an avoidance groove 3311, and the avoidance groove 3311 is located between the two ends of the sleeve 331, so that the middle part of the damping shaft 333 inserted in the sleeve 331 is exposed from the avoidance groove 3311, so that the damping shaft 333 is connected to the damping shaft 333 exposed in the avoidance groove 3311. In this way, one end of the damping shaft 333 is limited in the avoidance groove 3311, which can prevent the damping shaft 333 from sliding along the length direction of the damping shaft 333, thereby improving the matching stability of the damping shaft 333 and the damping shaft 333. In addition, the damping shaft 333 can be roughly located in the middle of the storage box 100 and connected to the second box body 13, so that the damping shaft 333 and the second box body 13 are evenly stressed, thereby improving the stability of the opening and closing process of the second box body 13.

[0079] Please refer to Figure 8 In some embodiments of the present application, the avoidance groove 3311 is located between the two ends of the sleeve 331, the damping shaft 333 includes a limiting section 3331 and two plug-in sections 3333 respectively located at the two ends of the limiting section 3331, the cross-section of the limiting section 3331 is larger than the cross-section of the plug-in section 3333, the limiting section 3331 is limited to the avoidance groove 3311, and the two plug-in sections 3333 are respectively inserted in the sleeves 331 at the two ends of the avoidance groove 3311.

[0080] In this embodiment, the damping shaft 333 includes a limiting section 3331 and two plug-in sections 3333 at both ends of the limiting section 3331. The cross section of the limiting section 3331 is larger than the cross section of the plug-in section 3333 and is not smaller than the cross section of the shaft hole of the sleeve 331. Correspondingly, the sleeve 331 is provided with an avoidance groove 3311 between both ends. The two plug-in sections 3333 of the damping shaft 333 are respectively inserted into the sleeve 331 at both ends of the avoidance groove 3311, and the limiting section 3331 is located in the avoidance groove 3311 area. In this arrangement, the limiting section 3331 is restricted in the avoidance groove 3311 and cannot enter the inner hole of the sleeve 331, so that the damping shaft 333 can be limited in the length direction of the damping shaft 333 to prevent the damping shaft 333 from moving axially or escaping from the sleeve 331, thereby improving the overall structural stability.

[0081] Please refer to Figure 8 In some embodiments of the present application, the limiting section 3331 is spaced apart from the end of the avoidance groove 3311, the plug-in section 3333 is partially exposed in the avoidance groove 3311, and one end of the connecting rod 335 is sleeved on the plug-in section 3333 and is located between the end of the avoidance groove 3311 and the limiting section 3331.

[0082] In this embodiment, the limiting section 3331 is spaced apart from the end of the avoidance groove 3311, so that part of the plug-in section 3333 is exposed in the avoidance groove 3311. At this time, one end of the connecting rod 335 is sleeved on the part of the plug-in section 3333 exposed in the avoidance groove 3311, so that one end of the connecting rod 335 is clamped between the end of the avoidance groove 3311 and the limiting section 3331, so as to limit the connecting rod 335 in the axial direction of the damping shaft 333, avoid the connecting rod 335 from sliding on the damping shaft 333, and improve the positional structural stability between the connecting rod 335 and the damping shaft 333.

[0083] Please refer to Figure 1 and Figure 4 In some embodiments of the present application, the second box body 13 includes an upper cover 131 and a surrounding edge 133 arranged around the upper cover 131 , and the damping structure 33 is arranged on the inner wall of the surrounding edge 133 .

[0084] In this embodiment, the second box body 13 includes an upper cover 131 and a surrounding edge 133 arranged around the upper cover 131, so that the damping structure 33 is arranged on the inner wall of the surrounding edge 133. In this way, when the second box body 13 is closed relative to the first box body 11, the damping structure 33 is located on one side of the surrounding edge 133, and is not located on the top wall of the internal space of the storage box 100, thereby avoiding the damping structure 33 and the items being compressed and damaged when items are placed in the storage box 100, thereby improving safety in use.

[0085] Please refer to Figures 11 to 14 The connection relationship between the connecting rod 335 and the second box body 13 can also be such that the end of the connecting rod 335 away from the damping shaft 333 can be slidably disposed on the inner wall of the second box body 13. For example, a limit member 338 can be set on the inner wall of the second box body 13, and a slide groove 3381 is provided, so that one end of the connecting member can be slidably disposed in the slide groove 3381. In this way, when the second box body 13 rotates and opens and closes relative to the first box body 11, the second box body 13 drives the connecting member to rotate relative to the first box body 11, and makes one end of the connecting member slide along the slide groove 3381, thereby adjusting the relative position of the connecting member and the second box body 13, and avoiding that the connecting structure 30 locks the second box body 13 and causes interference between the first box body 11 and the second box body 13.

[0086] Further, in some embodiments, the limiting member 338 is provided with a limited space 3387 at the end of the slide slot 3381, and a limiting portion 3385 is provided between the limiting space 3387 and the side wall of the slide slot 3381. When the second box body 13 is opened, one end of the connecting member slides along the slide slot 3381 and is clamped in the limiting space 3387. In this way, when the second box body 13 is opened, one end of the connecting member slides along the slide slot 3381 until one end of the connecting member enters the limiting space 3387. Since the limiting portion 3385 is provided between the limiting space 3387 and the side wall of the slide slot 3381, the opening of the limiting space 3387 is slightly narrowed, and the connecting member cannot enter and exit the limiting space 3387 at will, so that the connecting member can be locked and limited, so that the second box body 13 maintains a stable position relationship compared with the first box body 11. In addition, when the limiting portion 3385 is protruded from the side wall of the slide groove 3381, the connecting piece can enter and exit the limiting space 3387 by applying a large external force, or the limiting portion 3385 can be set on the elastic cantilever 3383 in the following embodiment, and the opening of the limiting space 3387 is opened or reset by the elastic deformation of the elastic cantilever 3383, so that the connecting piece can enter and exit the limiting space 3387.

[0087] Referring to the figure, in some embodiments of the present application, the limiting member 338 includes a connecting portion and an elastic cantilever 3383, the connecting portion is provided with a movable groove, the elastic cantilever 3383 extends along the length direction of the movable groove, one end of the elastic cantilever 3383 is connected to one end of the movable groove, and the other end of the elastic cantilever 3383 is spaced from the other end of the movable groove to form a limiting space 3387;

[0088] A sliding groove 3381 is formed between the elastic cantilever 3383 and the side wall of the movable groove, and the limiting portion 3385 is protruded from one side of the elastic cantilever 3383 facing the sliding groove 3381 .

[0089] In this embodiment, the position where the slide groove 3381 is formed on the limiting member 338 roughly includes a connecting portion and an elastic cantilever 3383, a movable groove is formed in the connecting portion, the groove width of the movable groove is greater than the groove width of the slide groove 3381, at least one elastic cantilever 3383 is arranged in the movable groove, the elastic cantilever 3383 extends from one end of the movable groove to the other end, and the free end of the elastic cantilever 3383 is spaced apart from the other end of the movable groove to form a limiting space 3387, at this time, the slide groove 3381 is formed on one side of the elastic cantilever 3383, and the limiting portion 3385 is convexly arranged on the side of the free end of the elastic cantilever 3383 facing the slide groove 3381; in this way, when the connecting member enters the limiting space 3387 from the slide groove 3381, the connecting member abuts against the limiting portion 3385 and the elastic The cantilever 3383 moves toward the side away from the slide groove 3381, thereby driving the limiting part 3385 to move toward the side away from the slide groove 3381, so that the connecting piece can pass through the limiting part 3385 and enter the limiting space 3387. After the connecting piece enters the limiting space 3387, the elastic cantilever 3383 drives the limiting part 3385 to reset, and the connecting piece is now limited in the limiting space 3387. Similarly, when the connecting piece enters the slide groove 3381 from the limiting space 3387, the limiting part 3385 and the elastic cantilever 3383 give way. This arrangement avoids the rigid contact between the connecting piece and the limiting part 3385 when passing through the limiting part 3385, thereby causing greater wear, and reduces the driving force for driving the connecting piece in and out of the limiting space 3387, thereby improving the convenience of operation.

[0090] Please refer to the figure. In some embodiments of the present application, the limiting member 338 includes two elastic cantilevers 3383 which are arranged in a movable groove and side by side. A slide groove 3381 is formed between the two elastic cantilevers 3383. A limiting portion 3385 is protruded toward the slide groove 3381 at the end of at least one elastic cantilever 3383.

[0091] In this embodiment, two elastic cantilevers 3383 arranged side by side are provided in the limit member 338, and a slide groove 3381 is formed between the two elastic cantilevers 3383. It can be understood that since the second box body 13 is flipped open and closed relative to the first box body 11, and in the opening and closing process, since the movement direction of the second box body 13 is opposite, the connecting member will apply a thrust to different side walls of the slide groove 3381 due to different movement directions during the sliding process along the slide groove 3381. In this embodiment, both sides of the slide groove 3381 are set as elastic cantilevers 3383, so that when the connecting member applies a thrust to different side walls, the elastic cantilever 3383 on this side can produce an elastic avoidance action, thereby avoiding the rigid abutment of the connecting member against the side wall of the slide groove 3381 during the sliding process along the slide groove 3381 to generate a large friction force, so that the connecting member can slide along the slide groove 3381 more smoothly and reduce wear.

[0092] Please refer to the figure. In some embodiments of the present application, the connecting structure 30 also includes an elastic member 339, one end of the elastic member 339 is connected to the limiting member 338, and the other end is connected to the connecting member. The second box body 13 is opened relative to the first box body 11 so that one end of the connecting member slides along the slide groove 3381 and elastically stretches the elastic member 339.

[0093] In this embodiment, the elastic member 339 can be a spring, a gas spring, etc., which is not limited here, so that the elastic member 339 extends along the length direction of the slide groove 3381 and is respectively connected to the connecting member and the limit member 338, and the elastic member 339 is kept in a natural extension or elastic stretching state when the second box body 13 covers the first box body 11. In the process of opening the second box body 13 relative to the first box body 11, the connecting member slides along the slide groove 3381 and stretches the elastic member 339, so that the elastic member 339 provides elastic resistance to the connecting member. The setting of the elastic member 339 can pull the connecting member when the second box body 13 covers the first box body 11 so that the connecting member is locked relative to the limit member 338 to prevent the connecting member from sliding along the slide groove 3381.

[0094] In some embodiments, the elastic member 339 is a spring, and the limiting member 338 has a hanging portion protruding from one end of the slide groove 3381, so that one end of the spring is hung on the hanging portion and connected to the limiting member 338, thereby improving the convenience of disassembly and assembly of the elastic member 339.

[0095] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
