[0036] The utility model provides an earphone box 100.

[0037] In the embodiment of the present utility model, Figure 1-4 As shown, the earphone box 100 includes a box body 10 and a resistance mechanism 20.

[0038] Among them, the box body 10 includes a first box body 11 and a second box body 12 arranged opposite to each other, and the first box body 11 has an open end; the second box body 12 is rotatably connected to the first box body 11 through a rotating shaft 13, and can open or cover the open end of the first box body under the action of external force; the resistance mechanism 20 is respectively connected to the first box body 11 and the second box body 12, and is used to provide resistance for the opening and covering of the second box body 12.

[0039] The earphone box 100 serves to store earphones. Specifically, the earphones are stored in the first box body 11, and the earphone box 100 can be opened or closed by rotating the second box body 12 connected to the first box body 11, so as to take out and store the earphones. At the same time, by providing a resistance mechanism 20 connected to the first box body 11 and the second box body 12 respectively, the opening resistance and the closing resistance can be achieved, thereby ensuring that the second box body 12 of the earphone box 100 can be tightly fastened to the first box body 11 in the closed state, and the second box body 12 can always be kept at the maximum opening angle in the open state, without affecting the realization of functions such as taking in and putting in the earphones, thereby ensuring the user experience.

[0040] In an embodiment of the utility model, the resistance mechanism 20 includes a cam 23, a linear roller 22 and an elastic member 21. The cam 23 is installed on the rotating shaft 13, the elastic member 21 is connected to the first box body 11, one end of the linear roller 22 is connected to the compressed elastic member 21, and the other end cooperates with the cam 23 to form a linear roller 22-cam 23 mechanism.

[0041] The direct-acting roller 22 is a structure that can only move back and forth along a straight line. In the present embodiment, since one end of the direct-acting roller 22 is connected to the compression elastic member 21 and the other end is connected to the cam 23, based on the elastic force of the elastic member 21, the direct-acting roller 22 can limit the rotation of the cam 23 to a certain extent, thereby enabling the cam 23 and the rotating shaft 13 and the second box body 12 fixedly connected thereto to maintain the current position (open state or closed state), thereby providing resistance to the opening or closing of the second box body 12.

[0042] Specifically, if Figure 2 As shown, in the closed state, the elastic member 21 will give elastic force to the linear roller 22, and the linear roller 22 will apply it to the cam 23, giving the cam 23 an oblique upward force. Due to the support of the intermediate rotating shaft 13, when it reaches the front end of the second box body 12, the direction of the force will become oblique downward, so that the second box body 12 is tightly buckled to the second box body 12;

[0043] In the open state, if Figure 3As shown, the elastic member 21 will give elastic force to the linear roller 22, and the linear roller 22 applies it to the cam 23, giving the cam 23 an oblique upward force (forming a ninety-degree angle with the force during capping). Due to the support of the intermediate rotating shaft 13, when it reaches the front end of the second box body 12, the direction of the force will become oblique downward (forming a ninety-degree angle with the force during capping), thereby achieving the purpose of keeping the second box body 12 at the maximum opening angle.

[0044] When a force is applied to the second box body 12 and the force is greater than the elastic force of the elastic member 21, the second box body 12 will rotate, thereby driving the cam 23 to move along the track ( Figure 4 From C to B is the process from closing the cover to opening it to a certain angle. During this process, the hand will always feel resistance. When the motion trajectory passes point B, the second box body 12 will automatically and quickly open to the maximum angle. From A to B is the process from opening the cover to closing it to a certain angle. During this process, the hand will always feel resistance to opening the cover. When the motion trajectory passes point B, the upper cover will automatically and quickly close.

[0046] Specifically, one end of the bracket 221 is columnar, and the other end is U-shaped. The roller 222 is a cylindrical structure, which is rotatably connected to the U-shaped end of the bracket 221 through a pin shaft, and is in contact with the cam 23 through the outer peripheral surface.

[0047] In the embodiment of the utility model, the first box body 11 is provided with a limiter 113 for limiting the bracket 221 to move linearly. In this way, the limiter 113 and the bracket 221 can be used to limit the linear roller 22 to move linearly.

[0048] In the embodiment of the utility model, the limiting part 113 is a sleeve with one end open, and the other end of the bracket 221 relative to the roller 222 is inserted into the sleeve to contact and connect with the elastic member 21 located in the sleeve. The structure of the sleeve is simple and effective, and the limiting function of the bracket 221 can be realized here.

[0049] In other embodiments, the limiting portion 113 may also be a plurality of limiting rings arranged at intervals.

[0051] Specifically, a notch is formed on the side wall of the bottom shell 111, and the notch is used for inserting a part of the structure of the second box body into the accommodating cavity to be connected with the resistance mechanism 20, and is also used for providing an escape space for the rotation of the second box body.

[0052] Of course, in other embodiments, the resistance mechanism 20 may also be disposed outside the first box body.
