Description

Technical Field

[0001] The utility model relates to the field of earphones, in particular to a TWS earphone with a rotating cover. Background Art

[0002] With the rapid development of the headphone industry, TWS headphones have gradually become the mainstream of the headphone industry, and TWS headphones require a charging case.

[0003] Now the common way for TWS charging cases is to install a retaining spring at the rotating shaft position, and use the rebound of the retaining spring to achieve the purpose of closing the lid of the charging case, or to install a magnet on the upper inner support of the charging case, and install magnets with opposite polarity on the inner support, and achieve the purpose of closing the case by the principle of attraction between opposite poles of magnets.

[0004] Since the TWS charging case uses a spring cover technology, the rebound force of the spring will be lost during use, and as the use time increases, the rebound force of the spring will become looser and looser; and the magnetic cover will weaken as the frequency of use increases. Therefore, the above two methods of opening the cover are too simple, and as the use time increases, it will also affect the closing of the cover. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides Figure 1-7 The TWS earphones with a rotating cover shown include a charging base 1, a charging compartment 102 is provided at the top of the charging base 1, and a connecting ear 101 is provided at one end of the charging base 1 for mounting the entire device.

[0029] Also includes:

[0030] The upper cover structure is rotatably connected to the top of the charging base 1. The upper cover structure includes a surface shell 2 and an inner lining 3. A fixing plate 6 is provided between the bottom end of the inner lining 3 and the top of the charging base 1;

[0031] It should be noted that the cross-sectional shape and size of the surface shell 2 and the inner lining 3 are the same as those of the charging base 1 , so that the surface shell 2 and the inner lining 3 can maintain a close-fitting cover on the top of the charging base 1 .

[0032] Connector, the bottom of the connector passes through the surface shell 2 and the lining 3 in sequence and is fixedly connected to the top of the fixed plate 6. The connector is used for the rotational support of the upper cover structure on the top of the charging base 1.

[0033] Specifically, a supporting slot 201 is opened at one end of the surface shell 2, and a rotating slot 302 is opened at one end of the lining 3. The connecting piece passes through the supporting slot 201 and the rotating slot 302 in sequence and is fixed at the top of the fixed plate 6.

[0034] It should be noted that the cross-sectional shape of the supporting slot 201 is also "T"-shaped, so that the top of the connecting cover 4 is adapted to the structure of the supporting slot 201. Through such a structural setting, the connecting cover 4 can be supported and placed in the supporting slot 201. Therefore, under such a structural setting, when the connecting cover 4 is fixed to the fixing plate 6, under the restriction of the connecting cover 4, the face shell 2 cannot flip over or detach, and it can only rotate.

[0035] Specifically, the connecting part includes a connecting cover 4, which is configured as a "T"-shaped column. The top of the connecting cover 4 is rotated and inserted into the inner wall of the top of the supporting groove 201, and a plurality of connecting grooves 402 for connecting the fixed disk 6 are opened in the middle of the connecting cover 4.

[0036] Furthermore, a plurality of screw hole columns 601 are fixedly connected to the top of the fixing plate 6 , and the plurality of screw hole columns 601 are respectively inserted and connected in the plurality of connecting slots 402 .

[0037] It should be noted that, through the interpenetration cooperation between the screw hole column 601 and the connecting groove 402, the connecting cover 4 can be fixed to the top of the fixed disk 6 after the fastening bolt is threadedly inserted into the screw hole column 601. In this way, after the connecting cover 4 is fixed to the fixed disk 6, with the cooperation of the supporting groove 201, the connecting cover 4 will restrict and lock the shell 2 so that it can only rotate.

[0038] Furthermore, a plurality of balls 401 are arranged around the top of the connecting cover 4, and the plurality of balls 401 are slidably inserted and connected to the inner wall of the top of the supporting groove 201. The balls 401 are used to reduce the friction between the contact surface of the surface shell 2 and the connecting cover 4 when the surface shell 2 rotates.

[0039] It should be noted that, by providing the ball bearing 401 , the friction between the surface of the housing 2 and the connecting cover 4 is reduced when the housing 2 rotates. The provision of the ball bearing 401 also enables the housing 2 to rotate more smoothly.

[0040] Specifically, a plurality of connection slots 202 are arranged around the side of the bottom end of the face shell 2, and a plurality of connection rods 301 are arranged around the side of the top end of the lining 3, and the plurality of connection rods 301 are respectively inserted and connected with the plurality of connection slots 202.

[0041] It should be noted that the connection rod 301 and the connection slot 202 are in the form of mortise and tenon fitting. Through such a structural design, the surface shell 2 and the lining 3 are combined together, so that the two can rotate synchronously.

[0042] Specifically, a plurality of ball grooves 303 are provided at the bottom of the lining 3 and around the rotating through groove 302, a plurality of steel balls 5 are sleeved on the bottom of the fixed plate 6, and the plurality of steel balls 5 are respectively slidably inserted and connected in the plurality of ball grooves 303, and a support spring 501 is provided at the bottom of the steel ball 5, and the support spring 501 is provided at the top of the charging base 1.

[0043] It should be noted that the ball groove 303 is used to insert the portion of the steel ball 5 exposed at the top of the fixed plate 6, and the support spring 501 is set to enable the steel ball 5 to keep moving in the direction close to the ball groove 303. At the same time, under such a structural setting, the steel ball 5 rebounds and collides with the top of the fixed plate 6 and the inner wall of the ball groove 303, thereby emitting an effect and sound that simulates gear rotation.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
