The utility model provides an earphone charging box. Referring to fig. 1 to 3, the earphone charging box includes a box body 102, a charging module 303, and a top cover 101. The case 102 is used for accommodating the earphones 202, and the top cover 101 is used for covering and shielding the earphones 202 accommodated in the case 102. The box body 102 and the top cover 101 are rotatably connected, specifically, referring to fig. 5 to 7, the box body 102 has a connecting channel 501, the top cover 101 includes a rotating shaft 602, and the rotating shaft 602 is inserted into the connecting channel 501; the rotation shaft 602 can rotate relative to the wall surface of the connection channel 501, and accordingly, the top cover 101 can rotate relative to the case 102, and the user can open or close the earphone charging case by rotating the top cover 101.

A charging module 303 is installed in the case 102, and the charging module 303 is used for charging the headset 202. Referring to fig. 3, the charging module 303 includes an electronic control main board 301 and a battery 302. Automatically controlled mainboard 301 is connected with battery 302 electricity, and automatically controlled mainboard 301 has one and charges the interface (not specifically shown), and external power supply cable is used for charging for battery 302 through pegging graft with the interface that charges, the electric energy that external power supply cable provided. Referring to fig. 3 and 9, the electronic control main board 301 has spring contact pins 901, the spring contact pins 901 are used for contacting with contacts (not specifically shown) of the headset 202 so as to conduct a circuit, and the battery 302 charges the headset 202 through the spring contact pins 901. The specific circuit design of the charging module 303 is well known in the art and will not be described in detail here.

Referring to fig. 6 and 7, the top cover 101 further includes a connecting body 603, and an end surface of the connecting body 603 is a first interference surface 701 along an axial direction of the rotating shaft 602. The case 102 has a second interference surface 502, the second interference surface 502 faces the first interference surface 701, the connecting body 603 and the case 102 interfere with each other (here, the interference is similar to the interference fit between the hole and the shaft), correspondingly, the first interference surface 701 and the second interference surface 502 press against each other, the friction force applied to the first interference surface 701 by the second interference surface 502 can provide a damping feeling to the rotation of the top cover 101, and the friction can also maintain the stability of the opening angle of the top cover 101.

According to the earphone charging box, friction generated by interference and extrusion between the first interference surface 701 and the second interference surface 502 of the top cover 101 is utilized, so that the function of damping sense is achieved when the top cover 101 rotates, parts such as a damping hinge do not need to be arranged, and cost saving and assembly efficiency improvement are facilitated. In addition, the first interference surface 701 and the second interference surface 502 are both located in the axial direction of the rotating shaft 602, and some block-shaped components protruding into the earphone charging box along the radial direction of the rotating shaft are not needed, so that the occupied space inside the earphone charging box is small.

Referring to fig. 4 and 5, the case 102 has an escape notch 403, the connecting body 603 is provided in the escape notch 403, a wall surface of an end portion of the escape notch 403 in the axial direction of the rotating shaft 602 is a second interference surface 502, and the second interference surface 502 and the first interference surface 701 can be pressed against each other. The avoidance gap 403 mainly provides enough space for the top cover 101 to rotate, and the second interference surface 502 provided on the end wall of the avoidance gap 403 can reduce the structural complexity of the box 102. It should be noted that the second interference surface 502 actually refers to a vertical surface as shown by the dashed oval in fig. 5; in conjunction with fig. 4 and 5, in order to reduce the difficulty in molding the bottom case 308, the end wall of the escape notch 403 is coplanar with the end wall of the portion for forming the connecting groove 402 (see fig. 4), but actually, the portion for interference is shown by the dashed oval frame in fig. 5.

In some embodiments, the earphone charging box will adopt the following settings: setting two angles alpha and beta (0< alpha < beta), wherein alpha is the opening angle of the top cover 101 when the damping feeling starts to be generated, and beta is the maximum opening angle of the top cover 101; in the process of opening the earphone charging box, after the top cover 101 is turned over by an angle α, the first interference surface 701 and the second interference surface 502 start to interfere with each other; when the top cover 101 is turned over at an angle between α and β, the top cover 101 is damped in rotation. Since the friction between the first interference surface 701 and the second interference surface 502 corresponds to the resistance when the top cover 101 is rotated, the above arrangement can reduce the resistance when the earphone charging box is opened. If the first interference surface 701 and the second interference surface 502 interfere with each other when the opening angle of the top cover 101 is between 0 and β, the resistance to opening the top cover 101 of the closed earphone charging box is large, and it takes a lot of effort to open the closed earphone charging box.

To achieve the above arrangement, the connecting body 603 further includes a spacer 704. Referring to fig. 7, the spacer 704 is connected to the interference portion 703, the interference portion 703 is connected to one side of the spacer 704 facing the inside of the case 102, and an end surface of the spacer 704 is a spacer surface 702 along the axial direction of the rotation shaft 602; in fig. 7, the interference portion 703 and the spacer portion 704 are roughly divided as follows, and the connecting body 603 further has a dividing plane 705, the interference portion 703 being located forward of the dividing plane 705, and the spacer portion 704 being located rearward of the dividing plane 705. A gap is formed between the spacing surface 702 and the second interference surface 703, when the earphone charging box is in a closed state, the spacing portion 704 is accommodated in the avoidance gap 403, the spacing surface 702 is opposite to the second interference surface 703, and the connecting body 603 and the box body 102 do not interfere with each other; when the top cover 101 is turned over by a certain angle, the first interference surface 701 gradually enters the avoidance gap 403, and the first interference surface 701 starts to interfere with the second interference surface 703.

The first interference surface 701 is vertically arranged, the avoidance gap 403 is recessed from top to bottom, and the distance between the two second interference surfaces 502 which are distributed at intervals from left to right gradually decreases from top to bottom. For convenience of explanation of the principle of such an arrangement, the following description will be made with a point a on the first interference surface 701 (which may correspond to the tip of the first interference surface 701) as a reference point. Referring to fig. 7, 8, 10 and 11, in the process of turning the top cover 101 open, as the turning angle of the top cover 101 increases, the point a moves from top to bottom; the point a does not initially contact the second interference surface 502, and when the top lid 101 is turned over a certain angle (or when the point a is lowered to a certain height), the point a contacts the second interference surface 502 to generate a damping feeling. Further, since the first interference surface 701 is disposed vertically and the second interference surface 502 is disposed obliquely in the up-down direction, the amount of interference between the first interference surface 701 and the second interference surface 502 is initially small and then gradually increases, and accordingly, the pressure applied to the first interference surface 701 by the second interference surface 502 gradually increases. This arrangement can gradually change the amount of interference, reducing the feeling of jerking when the user turns the top cover 101.

Similarly, the second interference surface 502 may also adopt the following arrangement: the distance between the two second interference surfaces 502 gradually decreases in the direction from the inside of the case 102 to the outside of the case 102 (the first interference surface 701 is also vertically disposed). Referring to fig. 5, the second interference surfaces 502 are disposed obliquely, and the distance between the two second interference surfaces 502 is gradually reduced from front to back. As the opening angle of the top cover 101 increases, the point a moves from front to back (fig. 10 and 11 can be combined); the first interference surface 701 does not contact the second interference surface 502 at first, and when the top lid 101 is turned over by a certain angle (or after the point a moves to a certain position in a direction away from the inside of the box 102), the point a contacts the second interference surface 502 to generate a damping feeling. In addition, this arrangement also allows the amount of interference to be gradually changed, reducing the feeling of jerking when the user turns the top cover 101.

Other specific configurations of the cartridge 102 are described below.

Referring to fig. 3, the box body 102 includes a bottom shell 308 and a middle cover 306, the bottom shell 308 has a mounting cavity 304, the middle cover 306 has a receiving groove 201 for receiving the earphone 202, and the middle cover 306 is connected to one end of the bottom shell 308 near the top cover 101 to close the mounting cavity 304. The case 102 is designed with a bottom case 308 and a middle cover 306 in combination to facilitate installation of the charging module 303 into the mounting cavity 304. Middle cover 306 and bottom shell 308 are fixed by clamping to reduce the total number of parts of the charging box (e.g. reduce the number of screws for connection). Referring to fig. 3 and 4, the middle cover 306 has a clamping hole 305, the bottom cover 308 has a third clamping body 401, the third clamping body 401 is connected to a side wall of the mounting cavity 304, the third clamping body 401 is clamped into the clamping hole 305, and the third clamping body 401 abuts against a hole wall of the clamping hole 305 to prevent the bottom cover 308 and the middle cover 306 from being separated.

Referring to fig. 4 and 5, the bottom chassis 308 has a coupling groove 402, and the middle cover 306 covers an upper side of the coupling groove 402 to form a coupling passage 501. Therefore, the installation process of the rotation shaft 602 is substantially as follows, after the rotation shaft 602 is placed into the connection groove 402, the bottom case 308 and the middle cover 306 are connected, and the rotation shaft 602 is restrained in the connection channel 501. The arrangement can reduce the installation difficulty of the rotating shaft 602 and facilitate the assembly between the top cover 101 and the box body 102.

In some embodiments, the closed state of the earphone charging box is maintained by clamping between the box body 102 and the top cover 101. Referring to fig. 2, 6 and 9, the middle cover 306 includes a first clip body 203, the top cover 101 includes a second clip body 601, and a front protruding portion of the first clip body 203 can be hooked with the second clip body 601, thereby preventing the top cover 101 from being opened and maintaining the closed state of the earphone charging box. Compared with the mode of magnet attraction between the box body 102 and the top cover 101, the box body 102 and the top cover 101 are fixed in a clamping mode without mounting magnets, the total number of parts of the charging box of the earphone is saved, the cost is saved, and the assembly efficiency is improved.

In some embodiments, the top cover 101 may be prevented from further rotation by the interference between the connecting body 603 and the middle cover 306. Specifically, with reference to fig. 8 and 11, the front side surface of the connecting body 603 is a limiting surface 801, and the limiting surface 801 can abut against the middle cover 306; from the perspective of fig. 8, the section from point B to point C corresponds to the position-limiting surface 801. Referring to fig. 8, from point a to point B to point C, the distance between the outer surface of the connecting body 603 and the center of the rotating shaft 602 (corresponding to point D in fig. 8) becomes gradually larger; since the center of the rotating shaft 602 is fixed relative to the middle cover 306, the position-limiting surface 801 will abut against the middle cover 306 after the top cover 101 is opened at a certain angle. After the limiting surface 801 abuts against the top cover 101, the opening angle of the top cover 101 is the maximum opening angle.

Referring to fig. 3 and 9, the battery 302 and the electronic control main board 301 are disposed in the mounting cavity 304, and the top ends of the spring contact pins 901 penetrate through the middle cover 306 and extend into the accommodating groove 201. Referring to fig. 12, the middle cover 306 is not connected to the electronic control main board 301 through a screw fastener such as a screw, but is connected through some snap structures of some middle covers 306 themselves, so as to reduce the number of parts of the earphone charging box, save cost, and improve the assembly efficiency of the earphone charging box. Specifically, the middle cover 306 includes a first fixing body 1201 and a second fixing body 307, the first fixing body 1201 and the second fixing body 307 abut against the bottom side of the electronic control motherboard 301 to prevent the electronic control motherboard 301 from falling (equivalent to the first fixing body 1201 and the second fixing body 307 jointly support the electronic control motherboard 301), and the first fixing body 1201 and the second fixing body 307 are respectively located at two ends of the electronic control motherboard 301. As shown in fig. 12, there are one first fixing body 1201 and two second fixing bodies 307, and the first fixing body 1201 and the second fixing body 307 fix the electronic control main board 301 at three points, so that the fixing effect on the electronic control main board 301 is better. A first stationary body 1201 and a second stationary body 307 to electrically control the mounting of the main board 301. For example, the second fixing body 307 has elasticity, and during the assembling and disassembling process of the electronic control main board 301, a user can break the second fixing body 307 at a certain angle to leave enough space between the first fixing body 1201 and the second fixing body 307 for inserting or extracting the electronic control main board 301.

Some commercially available charging boxes for earphones attract the earphone 202 through a magnet to ensure that the contacts of the earphone 202 contact and conduct with the spring contact pins 901. In the charging box for earphones of the present invention, after the earphones 202 are placed in the receiving groove 201, the top of the inner side of the top cover 101 abuts against (or presses) the top of the earphones 202, so that the contacts of the earphones 202 contact the spring contact pins 901. Therefore, the magnet is not arranged in the earphone charging box, the number of parts is reduced, and the assembly efficiency of the earphone charging box is improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
