The shape of the second cavity 20 is usually consistent with the shape of the earphone box cover (not shown in the drawings), and the size of the second cavity 20 is usually matched with the size of the earphone box cover (not shown in the drawings).

[0031] After the sleeve body 1 and the cover 2 are correspondingly sleeved on the outer periphery of the earphone box body (not shown in the drawings) and the earphone box cover (not shown in the drawings), the cover 2 is opened relative to the sleeve body 1 as the earphone box cover (not shown in the drawings) is opened. After the earphone box cover (not shown in the drawings) and the earphone box body (not shown in the drawings) are covered, the bracket 3 is folded to limit the cover 2 from opening from the opening and closing surface of the earphone box cover (not shown in the drawings) and the earphone box body (not shown in the drawings) relative to the sleeve body 1, which plays a better protective role for the earphone box. The bracket 3 is unfolded to release the limit on the cover 2, making it convenient for the earphone box cover (not shown in the drawings) to open relative to the earphone box body (not shown in the drawings). The overall structure is compact and convenient to use.

[0032] Specifically, in this embodiment, one end of the bracket 3 is rotatably connected to the sleeve 1 through a rotating connection mechanism 6, and the rotating connection mechanism 6 is provided at the lower part of a surface of the sleeve 1 opposite to the bracket 3. The rotating connection mechanism 6 is, for example, a hinge, which is composed of a hinge shaft and a first hinge piece and a second hinge piece respectively rotatably connected to the hinge shaft, and the first hinge piece and the second hinge piece are respectively located on both sides of the hinge shaft. During installation, the first hinge piece can be fastened to the sleeve 1 by fasteners such as screws, and the second hinge piece can be fastened to the bracket 3 by fasteners such as screws, so that the bracket 3 can be rotatably connected to the sleeve 1, so that the bracket 3 can be vertically flipped and unfolded or folded and retracted relative to the sleeve 1 and the cover 2, and the unfolding angle of the bracket 3 can be adjusted conveniently.

[0033] Specifically, in this embodiment, a first groove 11 is provided on a surface of the sleeve body 1 opposite to the bracket 3, and the rotation connection mechanism 6 is arranged on the lower side of the first groove 11; that is, the hinge axis, the first hinge piece and the second hinge piece are all located at corresponding positions on the lower side of the first groove 11. A second groove 22 is provided on a surface of the sleeve cover 2 opposite to the bracket 3, and a snap-fitting portion 7 is provided on the upper side of the second groove 22 to snap-fit ​​with the limiting portion 4. The second groove 22 and the first groove 11 have the same depth. After the sleeve cover 2 is covered in place relative to the sleeve body 1, the second groove 22 and the first groove 11 are assembled to form a bracket receiving groove that is connected to each other in a groove, and the shape and size of the bracket receiving groove usually match the bracket 3.

[0034] The shape of the bracket 3 is annular, and the middle part of the annular bracket 3 is hollow; the first protrusion 12 and the second protrusion 23 accommodated in the middle part of the bracket 3 are provided in the first groove 11 and the second groove 22 on the surface of the sleeve body 1 and the sleeve cover 2 opposite to the bracket 3. The thickness of the first protrusion 12 is consistent with the depth of the first groove 11, and the outer peripheral side surface of the first protrusion 12 and the inner peripheral side surface of the first groove 11 form a first interval for accommodating the middle and lower part of the bracket 3. The thickness of the second protrusion 23 is consistent with the depth of the second groove 22, and the outer peripheral side surface of the second protrusion 23 and the inner peripheral side surface of the second groove 22 form a second interval for accommodating the upper part of the bracket 3. After the sleeve cover 2 is covered in place relative to the sleeve body 1, the second protrusion 23 and the first protrusion 12 are combined to form a folding matching block that can be inserted into the middle part of the bracket 3, and the first interval and the second interval are combined to form a space for accommodating the annular bracket 3, and the size of the space matches the size of the annular bracket 3.

[0035] In order to facilitate opening of the cover 2 relative to the cover body 1, a first notch 121 is provided on the edge of the first protrusion 12 close to the second protrusion 23, and a second notch 231 corresponding to the first notch 121 is provided on the edge of the second protrusion 23 close to the first protrusion 12. Both the first notch 121 and the second notch 231 are convenient for hand-holding and force application.

[0036] The upper and lower sides of the annular bracket 3 are both straight lines, the left and right sides of the annular bracket 3 are both arc-shaped and convex outward, and any adjacent side edges are connected in an arc-shaped transition.

[0037] Specifically, in this embodiment, the limiting portion 4 is disposed on the bracket 3 at one end away from the rotating connection mechanism 6 and opposite to the cover 2. Figure 1 As shown in the figure, the rotation connection mechanism 6 is located at the lower part of the sleeve body 1 (i.e., the first groove 11) and the bracket 3, and the upper part of the bracket 3 is used to limit the position with the cover 2 located above the sleeve body 1, so the limiting part 4 is located at the upper part of the bracket 3. Among them, the limiting part 4 includes a protrusion 41 provided on the bracket 3 and a block 42 provided on the protrusion 41; the protrusion 41 is provided on a surface of the bracket 3 opposite to the cover 2; the block 42 is provided on a surface of the protrusion 41 opposite to the cover 2.

[0038] Specifically, in this embodiment, the engaging portion 7 includes a third groove 71 provided on the upper side of the second groove 22 and a fourth groove 72 provided in the third groove 71; the protrusion 41 is engaged with the third groove 71, and the clamping block 42 is engaged with the fourth groove 72. When the bracket 3 is folded and retracted, the protrusion 41 is engaged with the third groove 71, and the clamping block 42 is clamped in the fourth groove 72, so that the cover 2 is limited by the tight fit between the protrusion 41 and the third groove 71 and the clamping block 42 and the fourth groove 72. If the bracket 3 needs to be unfolded, the upper part of the bracket 3 is buckled by hand to make the protrusion 41 disengage from the third groove 71 and the clamping block 42 disengage from the fourth groove 72.

[0039] In order to facilitate holding the upper part of the bracket 3 by hand so that the protrusion 41 can be disengaged from the third groove 71 and the block 42 can be disengaged from the fourth groove 72, in this embodiment, fifth grooves 21 are correspondingly opened on both sides of the fourth groove 72 in the third groove 71, and the upper parts of the third groove 71, the fourth groove 72 and the two fifth grooves 21 all penetrate the top surface of the cover 2, so that after the bracket 3 is folded, a gap is formed between the protrusion 41 thereon and the cover 2, which is convenient for holding it by hand to unfold the bracket 3.

[0040] In this embodiment, the shape of the block 42 is rectangular, the upper surface of the protrusion 41 is set as an inclined surface and the inclined surface faces the cover 2. The inclined surface forms an angle with the top surface of the bracket 3, which further facilitates the hand to buckle the upper part of the bracket 3.

[0041] Among them, the lower surface of the protrusion 41 that contacts the third groove 71 is set as an inner concave arc surface; the lower surface of the third groove 71 that contacts the protrusion 41 is set as an outer convex arc surface, so that the bracket 3 can be unfolded or folded more smoothly. The inner side surfaces of the two fifth grooves 21 are also set as inner concave arc surfaces, which are more beautiful and practical. The depth of the fourth groove 72 is greater than the depth of the two fifth grooves 21 to ensure that the stability of the engagement between the block 42 and the fourth groove 72 is better.

[0042] Specifically, in this embodiment, the bracket 3 is further provided with a magnetic attraction mechanism 5 for magnetically attracting the electronic device.

[0043] The magnetic attraction mechanism 5 includes a sixth groove 51 formed on the bracket 3 and a magnetic attraction sheet 52 disposed in the sixth groove 51; the sixth groove 51 is formed on a surface of the bracket 3 facing away from the sleeve body 1 and the sleeve cover 2. Figure 6 As shown in , there are two sixth grooves 51, which are correspondingly opened on the left and right sides of the annular bracket 3. The two sixth grooves 51 are also arc-shaped and convex outward, and the curvature of the two sixth grooves 51 is consistent with the left and right sides of the annular bracket 3. The number of magnetic sheets 52 corresponds to the number of sixth grooves 51, and the size of the magnetic sheets 52 matches the sixth grooves 51.

[0044] Among them, since the position and support angle of the bracket 3 relative to the sleeve 1 and the cover 2 can be adjusted at any time by rotating the connecting mechanism 6, when the bracket 3 is unfolded, the bracket 3 can be adjusted to any position and angle suitable for supporting the electronic device, and then the earphone box with the sleeve 1 and the cover 2 is placed on a stable platform in a suitable posture or angle (if a certain angle with the bracket 3 is required), the electronic device can be magnetically supported by the magnetic sheet 52 on the bracket 3, or the bracket 3 can be used to magnetically support the electronic device after it is folded. The electronic device in this embodiment includes but is not limited to a mobile smart terminal, such as a mobile phone.

[0045] In other embodiments, the sixth groove 51 may also be any other suitable shape. The drawings of this embodiment are only examples and do not constitute specific limitations. In actual application, the design and selection can be carried out according to actual requirements.

[0046] In this embodiment, the sleeve 1 is also provided with a lanyard opening 101, a USB opening 102 and an indicator light opening which are connected to the interior of the first cavity 10. Among them, the lanyard opening 101 is used to connect a lanyard to further improve the convenience of carrying. The USB opening 102 is used to expose the interface of the earphone box to facilitate the connection of the charging data cable. The indicator light opening is used to display the indicator light of the earphone box. It should be noted that the lanyard opening 101, the USB opening 102 and the indicator light opening can be respectively arranged at any suitable position on the sleeve 1. The accompanying drawings are only examples and do not constitute specific limitations. The actual application shall prevail.

[0047] It is understandable that in other embodiments, the bracket 3 can also be rotatably connected to the cover 2 through the rotating connection mechanism 6. The specific connection structure and method are described in the above embodiment and will not be repeated here. The damping size of the rotating connection mechanism 6 also needs to be designed and selected according to actual requirements, and is not specifically limited here.
