[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1 As shown, the present application provides an earphone charging box, comprising a lower shell component 100 and an upper shell component 200. The upper shell component 200 is rotatably connected to the lower shell component 100, and the upper shell component 200 can be operated to be opened or closed.

[0033] It should be noted that the lower shell component 100 is provided with an earphone slot for accommodating earphones, and the upper shell component 200 can cover the earphones when it is in a closed state, and can facilitate the placement and removal of the earphones when it is in an open state. The earphones are TWS smart earphones, and the earphones can be configured with call noise reduction function and / or artificial intelligence noise reduction function, and can also be configured with stereo surround and other functions.

[0034] like Figure 2 As shown, the lower shell assembly 100 and the upper shell assembly 200 are rotatably connected via a hinge mechanism 300 .

[0035] Combination Figure 2 and Figure 4 The lower shell component 100 is provided with a first shaft hole 110 , and the lower shell component 100 is provided with a limiting column 120 on the side of the first shaft hole 110 .

[0036] Specifically, a groove 130 is provided on the edge of the top of the lower shell assembly 100 , the first axial hole 110 is opened on the lower shell assembly 100 from the side wall of the groove 130 , and the limiting column 120 is arranged on the side wall of the groove 130 and is located next to the first axial hole 110 .

[0037] like Figure 2 As shown, the upper housing assembly 200 is provided with a second shaft hole 210 corresponding to the first shaft hole 110 .

[0038] Combination Figure 1 , Figure 2 and Figure 4 Specifically, the upper shell component 200 has a connecting portion 220 that penetrates into the groove 130 , the second shaft hole 210 is opened in the connecting portion 220 , and the second shaft hole 210 is arranged opposite to the first shaft hole 110 .

[0039] It should be noted that the connection portion 220 can be made of plastic to save costs.

[0040] Combination Figure 2 and Figure 3 The hinge mechanism 300 includes a rotating shaft 310, an elastic member 320 and a limiting member 330. The rotating shaft 310 is inserted into the first shaft hole 110 and the second shaft hole 210. The limiting member 330 is sleeved outside the rotating shaft 310 and is arranged in the second shaft hole 210. The limiting member 330 can rotate with the upper shell assembly 200 relative to the lower shell assembly 100, and the limiting member 330 can move axially along the rotating shaft 310. The side of the limiting member 330 close to the first shaft hole 110 is provided with at least two positioning grooves 331 arranged at intervals along the circumference of the rotating shaft 310. The limiting column 120 is located on the rotation path of the at least two positioning grooves 331, and the elastic member 320 is pressed against the side of the limiting member 330 away from the first shaft hole 110.

[0041] It is understandable that the rotating shaft 310 is inserted into the first shaft hole 110 and the second shaft hole 210, so as to realize the rotation connection between the upper shell component 200 and the lower shell component 100. In the process of opening the upper shell component 200, the limiting member 330 will rotate relative to the lower shell component 100 together with the upper shell component 200, so that the limiting column 120 will first escape from the positioning groove 331 and push the limiting member 330 away from the first shaft hole 110, so that the limiting member 330 squeezes the elastic member 320, so that the user will feel the force during the opening process; when the upper shell component 200 is further opened, and when the other positioning groove 331 is opposite to the limiting column 120, under the action of the elastic member 320, the limiting member 330 will move toward the first shaft hole 110 again, so that the limiting column 120 is stuck in the positioning groove 331, so as to realize the limitation of the upper shell component 200, and prevent the upper shell component 200 from automatically closing or shaking under the action of gravity.

[0042] like Figure 2 As shown, in some embodiments, the hole wall of the second axial hole 210 forms a limiting step 211, the elastic member 320 is passed through the second axial hole 210, and one end of the elastic member 320 abuts against the limiting step 211, and the other end abuts against the side of the limiting member 330 away from the first axial hole 110.

[0043] It is understandable that the limiting step 211 is formed on the hole wall of the second shaft hole 210, and the limiting step 211 is located on the side of the limiting member 330 away from the first shaft hole 110, and the elastic member 320 is held between the limiting step 211 and the limiting member 330, and can apply a force to the limiting member 330, so that the limiting member 330 has a tendency to move toward the first shaft hole 110. In this way, when the limiting column 120 is inserted into the positioning groove 331, the limiting member 330 can keep the limiting member 330 pressed tightly, thereby preventing the upper shell assembly 200 from shaking.

[0044] The elastic member 320 is a spring, which is sleeved outside the rotating shaft 310. The rotating shaft 310 can position the spring to prevent the spring from being misplaced.

[0045] Of course, in other embodiments, the elastic member 320 may also be other elastic components such as a spring sheet, elastic rubber, etc.

[0046] It should be noted that the limiting member 330 has a central hole 332 , the rotating shaft 310 is inserted into the central hole 332 , and the limiting member 330 can move relative to the rotating shaft 310 along the axial direction of the rotating shaft 310 .

[0047] like Figure 2As shown, in some embodiments, the stopper 330 cooperates with the hole wall of the second shaft hole 210 through a circumferential stopper structure, and the circumferential stopper structure is used to limit the stopper 330 from rotating relative to the second shaft hole 210 around the axis of the second shaft hole 210. In this way, the stopper 330 can rotate as the upper shell assembly 200 rotates relative to the lower shell assembly 100, and the stopper 330 can also be prevented from rotating relative to the upper shell assembly 200 around the axis of the second shaft hole 210, thereby preventing the stopper 330 from losing its function.

[0048] Combination Figure 2 and Figure 6 Specifically, the circumferential limiting structure includes a first plane 333 provided on the side wall of the limiting member 330 and a second plane provided on the hole wall of the second axial hole 210, and the first plane 333 is arranged opposite to the second plane.

[0049] It is understandable that the first plane 333 and the second plane are in parallel and opposite positions. Thus, under the common limitation of the first plane 333 and the second plane, the limiting member 330 can be limited from rotating around the axis of the second shaft hole 210 relative to the second shaft hole 210 .

[0050] The side wall of the limiting member 330 includes four first planes 333 , which are four side surfaces of the limiting member 330 . The hole wall of the second axial hole 210 forms four second planes, which are respectively arranged opposite to the four first planes 333 .

[0051] like Figures 4 to 6 As shown, in some embodiments, the number of the limit column 120 is at least one, the number of the positioning grooves 331 is at least one group, one limit column 120 corresponds to a group of positioning grooves 331, a group of positioning grooves 331 includes at least two positioning grooves 331 arranged at circumferential intervals along the second axial hole 210, and the limit column 120 is located on the rotation path of all the positioning grooves 331 in the group of positioning grooves 331 corresponding to the limit column 120.

[0052] Specifically in this embodiment, there are two limiting posts 120, and there are two groups of positioning grooves 331. The two limiting posts 120 correspond to the two groups of positioning grooves 331, respectively. Each group of positioning grooves 331 includes two positioning grooves 331. In the limiting posts 120 and the corresponding group of positioning grooves 331, the limiting posts 120 are located on the rotation path of all the positioning grooves 331 in the group of positioning grooves 331. By using multiple limiting posts 120 and multiple groups of positioning grooves 331, the stability of the upper shell assembly 200 being limited can be improved.

[0053] Furthermore, when the upper shell assembly 200 is in a fully closed state, the limiting post 120 is inserted into one of the positioning grooves 331 of the corresponding group of positioning grooves 331, and when the upper shell assembly 200 is opened by a preset angle, the limiting post 120 is inserted into another positioning groove 331 of the corresponding group of positioning grooves 331. In this way, the upper shell assembly 200 can be kept in a closed state without the aid of magnets.

[0054] The preset angle may be an angle between 70° and 120°.

[0055] like Figure 6 As shown, in some embodiments, in each adjacent two positioning grooves 331 of each group of positioning grooves 331, the groove wall of any positioning groove 331 on the side close to the other positioning groove 331 is an inclined wall 3311 that gradually inclines toward the other positioning groove 331 along a preset direction, wherein the preset direction is the direction from the second axial hole 210 to the first axial hole 110.

[0056] Specifically, each group of positioning grooves 331 includes two positioning grooves 331, one of which is a first positioning groove and the other is a second positioning groove. The first positioning groove and the second positioning groove are arranged adjacent to each other. The groove wall of the first positioning groove on the side close to the second positioning groove is an inclined wall 3311 gradually inclined toward the second positioning groove along a preset direction, and the groove wall of the second positioning groove on the side close to the first positioning groove is an inclined wall 3311 gradually inclined toward the first positioning groove along a preset direction. In this way, when the upper shell assembly 200 is in the process of opening or closing the cover, the corresponding inclined wall 3311 can guide the limiting column 120, so that the limiting column 120 can slide out of the positioning groove 331 smoothly.

[0057] Furthermore, in each group of positioning grooves 331 , in the two positioning grooves 331 closest to the side, the groove wall of any positioning groove 331 away from the other positioning grooves 331 is a limiting wall 3312 .

[0058] Specifically, each group of positioning grooves 331 includes at least two positioning grooves 331. In the arrangement direction of the at least two positioning grooves 331, the first positioning groove 331 is the first positioning groove, and the last positioning groove 331 is the last positioning groove. The first positioning groove and the last positioning groove are the two positioning grooves 331 closest to the edge. In the two positioning grooves 331 closest to the edge, the groove wall of any positioning groove 331 away from the other positioning grooves 331 is a limiting wall 3312, and the limiting wall 3312 is used to limit the limiting column 120 to prevent the limiting column 120 from turning over.

[0059] Combination Figure 5 and Figure 6In some embodiments, the limiting column 120 is cylindrical. When the cylindrical limiting column 120 and the inclined wall 3311 of the positioning groove 331 are in contact, the friction between the two is smaller, which can reduce the risk of wear.

[0060] In the earphone charging box of the present invention, the rotating shaft 310 is arranged in the first shaft hole 110 and the second shaft hole 210, so as to realize the rotation connection between the upper shell component 200 and the lower shell component 100. In the process of opening the upper shell component 200, the limiting member 330 will rotate relative to the lower shell component 100 together with the upper shell component 200, so that the limiting column 120 will first escape from the positioning groove 331 and push the limiting member 330 away from the first shaft hole 110 so that the limiting member 330 squeezes the elastic member 320, so that the user will feel the force during the opening process; when the upper shell component 200 is further opened, and when the other positioning groove 331 is opposite to the limiting column 120, under the action of the elastic member 320, the limiting member 330 will move toward the first shaft hole 110 again, so that the limiting column 120 is stuck in the positioning groove 331, so as to realize the limitation of the upper shell component 200, and prevent the upper shell component 200 from automatically closing or shaking under the action of gravity.
