Description

Technical Field

[0001] The present application relates to an opening and closing mechanism, and in particular to an opening and closing mechanism for an earphone box cover. Background Art

[0002] Due to their small size, wireless Bluetooth earbuds cannot accommodate large batteries, resulting in short battery life and frequent charging. To facilitate charging and storage, a dedicated earbud case can be used to hold them. To charge, simply open the lid of the case and place the earbuds inside.

[0003] The existing earphone box lids are mainly opened and closed in two ways: flip-top and sliding. In order to increase the diversity of opening methods for the earphone box, the lid can also be opened and closed by rotation. For example, multiple slides and multiple sliders can be provided on the lid and the box body, respectively, and a rotating fitting and multiple blades can be provided between the lid and the box body. An opening is provided on the lid for taking out and putting in wireless Bluetooth headphones, and the multiple blades are used to open and close the opening. The rotation of the lid drives the rotating fitting to rotate, and the rotating fitting then drives the multiple blades to rotate along the multiple slides on the lid and the box body via the slider. The multiple blades rotate to open or close the opening. However, this lid opening and closing method requires the provision of a rotating fitting between the lid and the box body, multiple slides on the lid and the box body, and a slider, resulting in a relatively complex rotary lid opening and closing structure. Therefore, the existing rotary lid opening and closing structure has the problem of a relatively complex structure. Summary of the Invention

[0074] like Figure 1 As shown, in one embodiment, there is provided an earphone box cover opening and closing mechanism 1 for opening and closing an earphone box for storing earphones 2. The earphone box cover opening and closing mechanism 1 includes: a shell 10, a covering assembly 11 and a moving part 12. The shell 10 includes an axially arranged opening 100, and the earphones 2 can enter and exit the shell 10 through the opening 100. The covering assembly 11 includes a cover plate 110 and a connecting rod 111. The cover plate 110 and the shell 10 are rotatably connected, and one end of the connecting rod 111 is rotatably connected to the cover plate 110. The moving part 12 is rotatably connected to the other end of the connecting rod 111, and the moving part 12 is rotatably connected to the shell 10. When the moving part 12 rotates relative to the shell 10, the cover plate 110 of the covering assembly 11 can be driven to rotate through the connecting rod 111 of the covering assembly 11 to open or cover the opening 100.

[0075] By providing a shell 10, a cover assembly 11 and a moving part 12, an opening 100 is provided in the axial direction of the shell 10, so that the earphone 2 can enter and exit the shell 10 through the opening 100. The cover assembly 11 includes a cover plate 110 and a connecting rod 111, the cover plate 110 and the shell 10 are rotatably connected, one end of the connecting rod 111 is rotatably connected to the cover plate 110, the other end of the connecting rod 111 is rotatably connected to the moving part 12, and the moving part 12 is rotatably connected to the shell 10. Since when the moving part 12 rotates relative to the shell 10, the cover plate 110 of the cover assembly 11 can be driven to rotate by the connecting rod 111 of the cover assembly 11 to open or cover the opening 100, there is no need to respectively provide multiple slides on the cover body and the box body of the earphone box to realize the blade rotation to open or close the opening 100 (equivalent to a single connecting rod 111 that can replace the two slides on the cover body and the box body, as well as the corresponding slider), thereby simplifying the opening and closing structure of the box cover.

[0076] like Figure 1As shown, the shell 10 can be cylindrical, the moving part 12 can be annular, the opening 100 can be a circular hole arranged along the axial direction of the shell 10, and the opening 100 can be located at the top of the shell 10. The cover 110 can be triangular or fan-shaped as in subsequent embodiments. The outer shape of the connecting rod 111 can be arc-shaped, and its outer shape can bulge outward toward the inner circumferential wall of the shell 10, and its cross-section can be rectangular. The earphone 2 can be a Bluetooth earphone or a true wireless Bluetooth earphone, and the earphone 2 can be arranged inside the shell 10. The cover 110 can be rotatably connected to the top of the shell 10, and the moving part 12 can be rotatably connected to the top of the shell 10. For details on how the cover 110 and the shell 10 are rotatably connected, how the connecting rod 111, the cover 110 and the moving part 12 are rotatably connected, and how the moving part 12 and the shell 10 are rotatably connected, please refer to the subsequent content of the embodiment.

[0077] like Figure 2 As shown, for the convenience of description, a spatial rectangular coordinate system O-xyz can be set in the earphone box cover opening and closing mechanism 1, so that the Z axis of the coordinate system coincides with the central axis of the opening 100 and the shell 10.

[0078] like Figure 2 As shown, the connection end on the cover plate 110 connected to the housing 10 (for ease of explanation, designated as the first connection end 1100, which may be a circular through-hole on the cover plate 110), the connection end on the cover plate 110 connected to one end of the connecting rod 111 (for ease of explanation, designated as the second connection end 1101, which may be a circular blind hole on the cover plate 110), and the connection end on the moving member 12 connected to the other end of the connecting rod 111 (for ease of explanation, designated as the third connection end 120, which may be a circular blind hole on the moving member 12) may be spaced apart from each other. The line connecting the projections of the first connection end 1100, the second connection end 1101, and the third connection end 120 onto a radial plane of the housing 10 (for example, the radial plane may be the upper end surface of the support plate 101) may form a triangle, and the first connection end 1100 and the second connection end 1101 may be located on the same circle with the central axis of the opening 100 as a reference. The third connection end 120 may be located outside the first connection end 1100 and the second connection end 1101. The first connection end 1100 may be located at one corner of the cover 110, and the second connection end 1101 may be located at another corner of the cover 110. The third connection end 120 may be located at the bottom end of the moving part 12.

[0079] like Figure 2As shown, the bottom surface of one end of the connecting rod 111 can abut against the top surface of the cover plate 110, and the top surface of the other end of the connecting rod 111 can abut against the bottom surface of the moving part 12. The housing 10, the opening 100 and the moving part 12 can be coaxially arranged, and the moving part 12 can rotate around the central axis of the housing 10 (for example, around the Z axis). The bottom end of the moving part 12 can abut against the top end of the housing 10. The moving part 12 can rotate in a clockwise or counterclockwise direction around the central axis of the housing 10. The user can pinch the moving part 12 with his hand to push the moving part 12 to rotate around the central axis of the housing 10.

[0080] like Figure 2 As shown, the covering component 11 (the covering component 11 please refer to Figure 1 ) also includes a pivot 13, which is arranged at an edge near the opening 100, and the cover 110 is pivoted to the shell 10 through the pivot 13. The pivot 13 can be arranged parallel to the axial direction of the opening 100. One end of the pivot 13 can be inserted into the first connecting end 1100, and the other end of the pivot 13 can be embedded in the top of the shell 10 (such as embedded in the top of the support plate 101 in the subsequent content of the embodiment). One end of the connecting rod 111 is pivoted to the cover 110, and the other end of the connecting rod 111 is pivoted to the moving part 12. Suppose the rotation axis when one end of the connecting rod 111 is pivoted to the cover 110 is the first rotation axis 14, and suppose the rotation axis when the other end of the connecting rod 111 is pivoted to the moving part 12 is the second rotation axis 15, then one end of the first rotation axis 14 can be pivoted to the second connecting end 1101, and the other end of the first rotation axis 14 can be inserted into one end of the connecting rod 111. One end of the second rotating shaft 15 can be pivotally connected to the third connecting end 120, and the other end of the second rotating shaft 15 can be passed through the other end of the connecting rod 111. The pivot 13, the first rotating shaft 14 and the second rotating shaft 15 can be arranged parallel to each other.

[0081] like Figure 2 As shown, when the moving part 12 rotates relative to the housing 10 (for example, around the Z axis), the covering component 11 (see the covering component 11 for details) can be used. Figure 1, the same below) drives the cover plate 110 of the covering assembly 11 to rotate around the pivot 13 to open or cover the opening 100. How the connecting rod 111 drives the cover plate 110 to rotate around the pivot 13 to open or cover the opening 100 can refer to the subsequent content of the embodiment. The number of cover plates 110 can be single or multiple. When the number of cover plates 110 is single, the area of ​​a single cover plate 110 needs to be greater than or equal to the area of ​​the opening 100, and the edge of the opening 100 needs to have enough space to place the cover plate 110 after leaving the opening 100. The single cover plate 110 can be circular, and the single cover plate 110 can open or cover the opening 100 after rotating around the pivot 13. When the number of cover plates 110 is multiple, the area of ​​the multiple cover plates 110 after splicing together needs to be greater than or equal to the area of ​​the opening 100. How the multiple cover plates 110 are specifically spliced ​​together to cover the opening 100 can refer to the content in the subsequent embodiments.

[0082] like Figure 3 As shown, preferably, the housing 10 includes a radially arranged support plate 101, the support plate 101 and the peripheral wall of the housing 10 are sealed, the opening 100 and the pivot 13 (the pivot 13 is shown in FIG. Figure 2 , the same below) is provided on the support plate 101, and the cover plate 110 and the support plate 101 are pivotally connected via the pivot 13. For example, a connecting blind hole 1010 can be provided on the support plate 101 (please refer to the connecting blind hole 1010 for details). Figure 2 , the same below), one end of the pivot 13 is embedded in the connecting blind hole 1010, and the other end of the pivot 13 is passed through the first connecting end 1100 (please refer to the first connecting end 1100 Figure 2 ). The cover plate 110 can be in contact with the support plate 101. The bottom surface of the cover plate 110 and the moving part 12 can be arranged parallel to the support plate 101. The support plate 101 can be an annular plate, the support plate 101 can be sealed and connected to the inner peripheral wall of the shell 10, and the opening 100 can be arranged at the center position of the support plate 101. The support plate 101 can be arranged near the top of the shell 10. The support plate 101 and the shell 10 can be connected by gluing or integral molding. The support plate 101 is sealed and connected to the peripheral wall of the shell 10, and the opening 100 is arranged on the support plate 101, so that once the opening 100 is blocked by the cover plate 110, external dust can neither enter the interior of the shell 10 from the opening 100 nor enter the interior of the shell 10 from other positions of the support plate 101, which can prevent external dust or other foreign matter from entering the interior of the shell 10 from the support plate 101.

[0083] like Figure 3 As shown, preferably, the moving part 12 includes a circumferentially arranged cutout 121 (refer to the cutout 121). Figure 2, the same below) and an axially arranged through hole 122, the top of the shell 10 is embedded in the cutout 121. For example, the outer peripheral wall of the cutout 121 can be tangent to the top of the inner peripheral wall of the shell 10, and the top surface of the cutout 121 can be against the top surface of the shell 10 to achieve the top of the shell 10 embedded in the cutout 121. The cutout 121 can be arranged around the outer edge of the bottom end of the moving part 12 and coaxially with the opening 100. The cross-section of the cutout 121 can be rectangular. The through hole 122 can be a circular hole, and the through hole 122 can be arranged at the center position of the moving part 12. The diameter of the through hole 122 is larger than the diameter of the opening 100. The through hole 122 and the opening 100 can be coaxially arranged. The earphone 2 can enter and exit the shell 10 through the through hole 122. When the moving part 12 rotates around the central axis of the opening 100, it can pass through the covering component 11 (please refer to the covering component 11 Figure 1 , the same below) of the connecting rod 111 drives the cover plate 110 of the covering assembly 11 to rotate around the pivot 13 (the pivot 13 is referred to as Figure 2 ) rotates to open or cover the opening 100. The moving member 12 can be coaxially arranged with the housing 10.

[0084] like Figure 3 As shown, for example, when viewed from the top surface of the cover 110, the moving part 12 rotates clockwise around the central axis of the opening 100 (for example, around the Z axis), it can drive the connecting rod 111 to rotate, and after the connecting rod 111 rotates, it can drive the cover 110 to rotate around the pivot 13 (the pivot 13 is shown in FIG. Figure 2 , the same below) rotates in the clockwise direction to open the opening 100. When the moving part 12 rotates in the counterclockwise direction around the central axis of the opening 100, it can drive the connecting rod 111 to rotate. After the connecting rod 111 rotates, it can drive the cover plate 110 to rotate in the counterclockwise direction around the pivot 13 to cover the opening 100. By setting the circumferential notch 121 (please refer to the notch 121 for details), the opening 100 can be opened. Figure 2 , the same below), and the top end of the shell 10 is embedded in the cutout 121, which can limit the rotation direction of the moving part 12 to only around the central axis of the opening 100. Combined with the pivotal connection between the cover plate 110 and the support plate 101, the pivotal connection between the cover plate 110 and the connecting rod 111, and the pivotal connection between the connecting rod 111 and the moving part 12, the degree of freedom of the entire earphone box cover opening and closing mechanism 1 can be made 1, thereby making the earphone box cover opening and closing mechanism 1 have a certain movement.

[0085] like Figure 4 As shown, preferably, the multiple cover plates 110 and the multiple connecting rods 111 are arranged flush. For example, the top surfaces of the multiple cover plates 110 are arranged coplanarly and coplanar with the top surfaces of the multiple connecting rods 111 (the top surface of the connecting rod 111 can be a plane on the connecting rod 111 perpendicular to the Z axis). The bottom surfaces of the multiple cover plates 110 can be arranged coplanarly, and the bottom surface of each cover plate 110 can abut against the top surface of the support plate 101. It can be around the second connecting end 1101 (please refer to the second connecting end 1101 for details). Figure 2) is provided with a recessed portion 1102, so that one end of the connecting rod 111 is pivotally connected to the recessed portion 1102. The depth of the recessed portion 1102 can be substantially the same as the thickness of the connecting rod 111 so that the top surface of the connecting rod 111 and the top surface of the cover plate 110 are coplanar. The top surfaces of the multiple cover plates 110 are coplanar and coplanar with the top surfaces of the multiple connecting rods 111, so that the top surfaces of the multiple cover plates 110 and the top surfaces of the multiple connecting rods 111 can be aligned with the moving part 12 (see the moving part 12 for details). Figure 3 , the same below) is roughly equal, compared to when the top surface of the connecting rod 111 is higher than the top surface of the cover 110, the distance between the moving part 12 and the support plate 101 can be shortened, and the axial dimension of the earphone box cover opening and closing structure 1 can be reduced.

[0086] like Figure 4 As shown, in another embodiment, the covering component 11 (the covering component 11 is shown in FIG. Figure 1 , the same below) is multiple. For example, the number of cover components 11 can be 5. Multiple pivots 13 can be placed in the opening 100 (please refer to the opening 100 for details). Figure 3 , the same below), the cover plates 110 and the support plates 101 of the multiple covering components 11 are pivotally connected through the pivots 13, and the other ends of the connecting rods 111 of the multiple covering components 11 are pivotally connected to the moving parts 12 (please refer to the moving parts 12 Figure 3 , the same below), when the moving part 12 rotates (for example, rotates around the Z axis), the connecting rods 111 of the multiple covering components 11 can drive the cover plates 110 of the multiple covering components 11 to rotate synchronously around the corresponding pivots 13. After the cover plates 110 rotate synchronously around the corresponding pivots 13, they can be assembled together to cover the opening 100, or spread out to open the opening 100.

[0087] like Figure 4 As shown, with 5 covering components 11 (covering component 11 please refer to Figure 1 , the same below) and five pivots 13 as an example, namely the cover 110, the connecting rod 111, the first connecting end 1100 (the first connecting end 1100 please refer to Figure 2 , the same below), the second connection end 1101 (the second connection end 1101 please refer to Figure 2 , the same below), the third connection end 120 (the third connection end 120 please refer to Figure 2 , the same below), the number of the first rotating shaft 14 and the second rotating shaft 15 are both 5, the moving part 12 (moving part 12 please refer to Figure 2, the same below) and the number of support plates 101 is one. Each of the two corners of each cover plate 110 includes a first connection end 1100 and a second connection end 1101. Each pivot 13 is provided at the corresponding first connection end 1100 and is pivotally connected to the corresponding connection blind hole 1010. Each first rotation axis 14 is provided at the corresponding second connection end 1101 and is pivotally connected to one end of the corresponding connecting rod 111. Each second rotation axis 15 is provided at the corresponding third connection end 120 and is pivotally connected to the other end of the corresponding connecting rod 111. Each first connection end 1100, each second connection end 1101, each third connection end 120, each first rotation axis 14 and each second rotation axis 15 can all be provided with an opening 100 (please refer to the opening 100 for details). Figure 2 , the same below) is uniformly distributed with reference to the central axis of the opening 100, wherein each first connection end 1100, each second connection end 1101, each first rotation axis 14 and each second rotation axis 15 can be roughly located on a circle with the same radius with reference to the central axis of the opening 100, and each third connection end 120 can be roughly located on another circle with reference to the central axis of the opening 100, and the reference circle where each third connection end 120 is located can surround the outside of the reference circle where each first connection end 1100, each second connection end 1101, each first rotation axis 14 and each second rotation axis 15 are located.

[0088] like Figure 4 As shown, from the top surface of the cover 110, the moving part 12 (moving part 12 please refer to Figure 3 , the same below) around the opening 100 (opening 100 please refer to Figure 3 , the same below) rotates clockwise about the central axis (e.g., about the Z axis), it can drive each connecting rod 111 to rotate simultaneously. After each connecting rod 111 rotates simultaneously, it can drive each corresponding cover plate 110 to rotate simultaneously in the clockwise direction about each corresponding pivot 13 and spread apart from each other to open the opening 100. When the moving part 12 rotates counterclockwise about the central axis of the opening 100, it can drive each connecting rod 111 to rotate simultaneously. After each connecting rod 111 rotates simultaneously, it can drive each corresponding cover plate 110 to rotate simultaneously in the counterclockwise direction about each corresponding pivot 13 and assemble to cover the opening 100. After each cover plate 110 is assembled, a thin cylindrical cover can be formed to cover the opening 100. The shape and size of each cover plate 110 can be the same, and the upper and lower surfaces of each cover plate 110 can be respectively flush. The shape and size of each connecting rod 111 can be the same.

[0089] like Figure 4 As shown, preferably, a plurality of cover plates 110 are provided with openings 100 (please refer to the openings 100 for details). Figure 3, the same below) is evenly distributed with reference to the central axis, and adjacent cover plates 110 can abut each other from their sides to cover the opening 100. The sides of the cover plates 110 can be set parallel to the central axis of the opening 100, and each cover plate 110 can include two sides, and the sides of adjacent cover plates 110 abut each other in turn. The two sides of each cover plate 110 for abutting each other can be flat or curved with the same curvature. Multiple covering components 11 (please refer to the covering component 11) Figure 1 ) are evenly distributed with respect to the central axis of the opening 100. Adjacent cover plates 110 can abut against each other from their sides to shield the opening 100. Compared to shielding the opening 100 by stacking adjacent cover plates 110, since there is no overlapping portion of the adjacent cover plates 110 when the cover plates 110 abut against each other from their sides, there is no wasted area of ​​the cover plates 110 due to overlapping and forming duplicate shielding.

[0090] like Figure 4 As shown, preferably, each cover plate 110 is fan-shaped, each pivot 13 is connected to a position on the corresponding cover plate 110 away from the center of the cover plate 110, and multiple cover plates 110 rotate around the corresponding pivot 13 to assemble and cover the opening 100 (please refer to the opening 100 for details). Figure 2 , the same below), the centers of the respective cover plates 110 abut against each other and are approximately located at the central axis of the opening 100. For example, the first connecting end 1100 (the first connecting end 1100 please refer to Figure 2 , the position on the cover plate 110 away from the center of the cover plate 110 can be the first connection end 1100) can be a rounded corner of the fan-shaped cover plate 110, the second connection end 1101 (the second connection end 1101 please refer to Figure 2 ) may be another rounded corner of the fan-shaped cover plate 110. After the cover plates 110 rotate about their corresponding pivots 13 and join together to cover the opening 100, the centers of the circles of the cover plates 110 abut against each other and are approximately located at the central axis of the opening 100. This can prevent the formation of a gap at the central axis of the opening 100 after the cover plates 110 are joined, thereby preventing dust or other foreign matter from entering the interior of the housing 10.

[0091] like Figure 5As shown, preferably, after the cover plate 110 rotates about the pivot 13 to open the opening 100, the cover plate 110 is located between the opening 100 and the peripheral wall of the housing 10. For example, after the cover plate 110 rotates about the pivot 13 to open the opening 100, the cover plate 110 can be located at the top end of the housing 10 (such as the top surface of the support plate 101) and between the opening 100 and the inner peripheral wall of the housing 10. When there are multiple cover plates 110, after the multiple cover plates 110 rotate about the corresponding pivot 13 to spread out from each other to open the opening 100, each cover plate 110 is located between the opening 100 and the peripheral wall of the housing 10. For example, after the multiple cover plates 110 rotate about the corresponding pivot 13 to spread out from each other to open the opening 100, each cover plate 110 can be located on the top surface of the support plate 101 and dispersed between the opening 100 and the inner peripheral wall of the housing 10. After the cover 110 rotates around the pivot 13 to open the opening 100, the cover 110 is located between the opening 100 and the peripheral wall of the shell 10, that is, after the cover 110 rotates around the pivot 13 to open the opening 100, it will not block the earphone 2 from being taken out of the opening 100, and can prevent the user's hand or the earphone 2 from colliding with the cover 110 when the earphone 2 is taken out of the opening 100, causing the connection between the cover 110 and the shell 10 to become loose or damaged.

[0092] like Figure 6 As shown, the earphone box lid opening and closing mechanism 1 also includes a structure for raising and lowering the accommodating member 17, comprising a base 16 and an accommodating member 17. The accommodating member 17 can be located between the inner bottom surface of the base 16 and the bottom surface of the support plate 101. The housing 10 also includes a circumferentially arranged first guide portion 102. A second guide portion 160 is provided on the circumferential wall of the base 16, facing the first guide portion 102. The housing 10 can rotate relative to the base 16 about the central axis of the base 16. The accommodating member 17 is disposed on the base 16 and located within the housing 10. The accommodating member 17 is used to store the earphones 2. The accommodating member 17 includes a radially arranged third guide portion 170. One end of the third guide portion 170 passes through the second guide portion 160 and abuts the first guide portion 102. When the housing 10 rotates relative to the base 16 about the central axis of the base 16, the third guide portion 170 can rise or fall along the first guide portion 102 and the second guide portion 160, thereby driving the accommodating member 17 to rise or fall along the axial direction of the base 16. How the third guide portion 170 rises or falls along the first guide portion 102 and the second guide portion 160 may refer to the subsequent content of this embodiment.

[0093] By providing a first guide portion 102 circumferentially along the housing 10 and a second guide portion 160 on the peripheral wall of the base 16, with the second guide portion 160 oriented toward the first guide portion 102, the housing 10 can rotate relative to the base 16 about the central axis. A third guide portion 170 is provided radially along the accommodating member 17. One end of the third guide portion 170 passes through the second guide portion 160 and abuts the first guide portion 102. As the housing 10 rotates relative to the base 16 about the central axis, the third guide portion 170 can rise or fall along the first guide portion 102 and the second guide portion 160, thereby driving the accommodating member 17 to rise or fall axially along the base 16. Since the accommodating member 17 is provided with a third guide portion 170, and one end of the third guide portion 170 passes through the second guide portion 160 and abuts against the first guide portion 102, that is, the third guide portion 170 is generated from the radial protrusion of the accommodating member 17, it is not necessary to hollow out a part (for example, the hollowed-out part is a groove) on the accommodating member 17 as a guide portion, and the third guide portion 170 can drive the accommodating member 17 to rise or fall along the axial direction of the base 16, thereby avoiding the reduction in the strength of the accommodating member 17 due to the presence of the hollowed-out part as a guide portion.

[0094] For the convenience of description, the Z axis of the coordinate system is made to coincide with the central axis of the base 16 , and the XoZ plane of the coordinate system passes through the axial plane of the axial portion of the second guide portion 160 .

[0095] like Figure 7 As shown, preferably, the first guide portion 102 is spiral-shaped and is provided on the shell 10. For example, the first guide portion 102 can be provided on the inner circumferential wall of the shell 10 below the support plate 101. The first guide portion 102 can be located on half of the circumferential wall of the shell 10. The shell 10 and the base 16 can both be cylindrical in shape, and the container 17 can be in the shape of a cylindrical shell. The container 17 can be made of an elastic material, so that the container 17 can allow the third guide portion 170 to be snapped into the first guide portion 102 through its own deformation. The container 17 can be a plastic product, for example, it can be made of materials such as polyethylene terephthalate (PET), polyvinyl chloride (PVC) or polystyrene (PS) through a blister molding process. The container 17 is located in the base 16, and the earphone 2 can be provided in the container 17. When the container 17 rises to the highest position along the axial direction of the base 16, the user can get the earphone 2 through the opening 100 on the shell 10.

[0096] like Figure 8 As shown, the two first guide portions 102 are spaced apart from each other. The positional relationship of the two first guide portions 102 can be such that after one of the two first guide portions 102 is rotated 180 degrees around the central axis of the housing 10 (e.g., around the Z-axis), it can overlap with the remaining first guide portion 102 of the two first guide portions 102.

[0097] like Figure 8 As shown, the two second guide portions 160 are disposed in a one-to-one correspondence with the two first guide portions 102, and the two second guide portions 160 are spaced apart from each other. The positional relationship of the two second guide portions 160 can be such that after one of the two second guide portions 160 is rotated 180 degrees about the central axis of the housing 10 (e.g., about the Z-axis), it can overlap with the remaining second guide portion 160.

[0098] Please also refer to Figure 8 and Figure 9 , the first guide part 102 is a groove, the second guide part 160 is a guide groove, and the third guide part 170 is a protrusion. One end of the third guide part 170 passes through the second guide part 160 and is embedded in the first guide part 102. The first guide part 102 is a groove instead of being set as a through hole to avoid the third guide part 170 from being exposed from the radial direction of the shell 10 through the first guide part 102, thereby preventing the user's fingers from being pinched by the third guide part 170 and the shell 10 when the user rotates the shell 10. The cross-section of the first guide part 102 can be an arc shape, the cross-section of the second guide part 160 can be a rectangle, and the third guide part 170 can be a cylindrical protrusion extending radially along the peripheral wall of the accommodating part 17. The first guide part 102 and the shell 10 can be integrally formed, and the second guide part 160 and the base 16 (please refer to the base 16) Figure 7 ) can be integrally formed, and the third guide portion 170 and the accommodating member 17 can be integrally formed.

[0099] Please also refer to Figure 8 and Figure 9 The cross-sectional diameter of the first guide portion 102, the width of the second guide portion 160, and the cross-sectional diameter of the third guide portion 170 can be substantially the same. The cross-sectional diameters of the first guide portion 102 and the third guide portion 170 are substantially the same, and one end of the third guide portion 170 abuts against the first guide portion 102. This allows the first guide portion 102 to restrict one end of the third guide portion 170 to slide only around the first guide portion 102, preventing the third guide portion 170 from moving axially or radially in the housing 10.

[0100] Please also refer to Figure 8 and Figure 9 Preferably, the number of the first guide parts 102, the number of the second guide parts 160 and the number of the third guide parts 170 are all two. The number of the first guide parts 102, the number of the second guide parts 160 and the number of the third guide parts 170 can also be other values. Providing two first guide parts 102, two second guide parts 160 and two third guide parts 170 can make the container 17 and the base 16 (please refer to the base 16 for details) Figure 7, the same below) and the shell 10 have multiple force-bearing parts during relative movement, so that each first guide part 102, each second guide part 160 and each third guide part 170 bears less force. Compared with using a single first guide part 102, a single second guide part 160 and a single third guide part 170, each guide part (including each first guide part 102, each second guide part 160 and each third guide part 170, the same below) is less likely to be worn out too quickly due to excessive force on a single guide part, thereby increasing the service life of each guide part.

[0101] Please also refer to Figure 8 and Figure 9 The two third guide portions 170 are provided in a one-to-one correspondence with the two first guide portions 102, and the two third guide portions 170 are provided in a one-to-one correspondence with the two second guide portions 160, and the two third guide portions 170 are spaced apart from each other. The two third guide portions 170 can be symmetrically arranged about a plane passing through the central axis of the receiving member 17. For example, when the third guide portions 170 rotate to the axial portion of the second guide portion 160, the two third guide portions 170 can be symmetrically arranged about the YoZ plane.

[0102] like Figure 9 As shown, preferably, the base 16 (see base 16 Figure 7 , the same below) also includes a cone 161 and a cylinder 162, the cylinder 162 and the cone 161 are connected and coaxially arranged, for example, the cylinder 162 and the cone 161 can be integrally formed and connected. The shell 10 can be sleeved on the cylinder 162, and the bottom end of the shell 10 can abut against the top end of the cone 161. The cylinder 162, the opening 100 and the shell 10 are coaxially arranged, and the accommodating member 17 and the cylinder 162 are coaxially arranged, and the accommodating member 17 is located inside the cylinder 162, and the second guide portion 160 (please refer to the second guide portion 160) Figure 8 , the same below) is arranged on the peripheral wall of the cylinder 162. For example, the accommodating member 17 can be placed on the top surface of the cone 161. The second guide portion 160 can be a guide groove that passes through the peripheral wall of the cylinder 162 along the radial direction of the cylinder 162. The outer peripheral surface of the cylinder 162 is tangent to the inner peripheral surface of the shell 10, and the inner peripheral surface of the cylinder 162 is tangent to the outer peripheral surface of the accommodating member 17. The outer peripheral surface of the cylinder 162 is tangent to the inner peripheral surface of the shell 10, which can easily realize the coaxial arrangement of the cylinder 162 and the shell 10. The inner peripheral surface of the cylinder 162 is tangent to the outer peripheral surface of the accommodating member 17, which can easily realize the coaxial arrangement of the cylinder 162 and the accommodating member 17.

[0103] like Figure 10 As shown, preferably, the second guide portion 160 (the second guide portion 160 please refer to Figure 8, the same below) includes a circumferential slideway 1600 and an axial slideway 1601. The circumferential slideway 1600 and the axial slideway 1601 are connected and arranged perpendicular to each other. The circumferential slideway 1600 can be parallel to the end surface of the cone 161 (for example, it can be parallel to the XoY plane), and the axial slideway 1601 can be parallel to the central axis of the cylinder 162 (for example, it can be parallel to the Z axis).

[0104] like Figure 10 As shown, the housing 10 is arranged around the base 16 (refer to Figure 7 , the same below) rotates relative to the base 16 around its central axis, and when the third guide portion 170 is located on the circumferential slide 1600, the housing 10 can drive the third guide portion 170 to rotate along the circumferential slide 1600 (how the third guide portion 170 rotates along the circumferential slide 1600 can refer to the rising or falling process of the accommodating member 17 of the earphone box cover opening and closing mechanism 1 in the subsequent content of this embodiment). When the housing 10 rotates relative to the base 16 around its central axis, and when the third guide portion 170 is located on the axial slide 1601, the base 16 can drive the third guide portion 170 to rise or fall along the axial slide 1601 and the first guide portion 102 (how the third guide portion 170 rises or falls along the axial slide 1601 and the first guide portion 102 can refer to the rising or falling process of the accommodating member 17 of the earphone box cover opening and closing mechanism 1 in the subsequent content of this embodiment). The circumferential slideway 1600 is used to prevent the third guide portion 170 from continuing to rise or fall when the third guide portion 170 moves to a certain position (including moving to the highest position or the lowest position).

[0105] like Figure 10 As shown, preferably, there are two circumferential slideways 1600, which are disposed on either side of the axial slideway 1601. For example, one of the two circumferential slideways 1600 can be disposed at the top end of the axial slideway 1601, and the other can be disposed at the bottom end of the axial slideway 1601. The higher circumferential slideway 1600 is spaced a certain distance from the top end surface of the cylinder 162. This allows the third guide portion 170 to be caught by the higher circumferential slideway 1600 when it rises to the higher circumferential slideway 1600, preventing the third guide portion 170 from rising too far and sliding off the top end of the axial slideway 1601. The axial height of the first guide portion 102 can be roughly equal to the axial spacing between the two circumferential slides 1600, so that when the third guide portion 170 rises to the top end of the first guide portion 102, it can just be engaged with the higher circumferential slide 1600, and when the third guide portion 170 descends to the bottom end of the first guide portion 102, it can just be engaged with the lower circumferential slide 1600.

[0106] like Figure 10As shown, preferably, one end of the axial slideway 1601 is in communication with the end surface of the cylinder 162. For example, one end of the axial slideway 1601 may be in communication with the end surface of the top end of the cylinder 162. This communication between one end of the axial slideway 1601 and the end surface of the cylinder 162 allows the third guide portion 170 to be inserted into the second guide portion 160 from the end surface of the cylinder 162. This is more labor-saving and convenient than inserting the third guide portion 170 into the second guide portion 160 through the deformation and extrusion of the receiving member 17.

[0107] like Figure 10 As shown, the work process of the rising and falling of the receiving member 17 is as follows, wherein the rising of the receiving member 17 is to lift the earphone 2 to be exposed outside the opening 100. Therefore, before the receiving member 17 rises, the moving member 12 needs to be rotated first (the moving member 12 is shown in FIG. Figure 3 ) to drive the cover plate 110 (please refer to the cover plate 110 Figure 3 ) around the pivot 13 (pivot 13, please refer to Figure 3 ) is rotated to open the opening 100. When the accommodating member 17 is at the lowest position, the third guide portion 170 is located at the end of the lower circumferential slideway 1600 and the bottom end of the first guide portion 102, and the bottom of the accommodating member 17 abuts against the round table 161. The user holds the housing 10 with one hand and rotates the housing 10 in a first direction (for example, the first direction can be counterclockwise around the Z axis, and the first direction is in the Figure 10 The user holds the table 161 with his other hand and keeps it still (the table 161 can also be rotated in the opposite direction to the first direction, which can make the container 17 rise faster). The shell 10 (in this case, the bottom end of the first guide part 102 on the shell 10) begins to push the third guide part 170 to rotate along the circumferential slide 1600 at a lower position. When the third guide part 170 rotates to contact the axial slide 1601, it will be blocked by the axial slide 1601. At this time, the base 16 (that is, the bottom end of the axial slide 1601 on the base 16 (the bottom end of the axial slide 1601 is the part of the axial slide 1601 facing the circumferential slide 1600 at a relatively close position). Please refer to the base 16 Figure 7 , the same below) will push the third guide portion 170 to begin rising along the first guide portion 102 and the axial slideway 1601, and the third guide portion 170 will then push the container 17 to begin rising along the axial direction of the base 16 (for example, along the Z-axis direction). When the third guide portion 170 rises to the higher circumferential slideway 1600, the housing 10 (in this case, the top end of the first guide portion 102 on the housing 10) will push the third guide portion 170 into the higher circumferential slideway 1600, and the third guide portion 170 will stop when it abuts the end of the higher circumferential slideway 1600. At this point, the container 17 reaches its highest position, and the earphone 2 also reaches its highest position and can be removed from the opening 100 of the housing 10.

[0108] like Figure 11 As shown, when the receiving member 17 reaches the highest position, the user holds the housing 10 with one hand and rotates the housing 10 in the second direction (the second direction is opposite to the first direction, for example, the second direction can be a clockwise direction around the Z axis, and the second direction is opposite to the first direction). Figure 11 Indicated by the arrow around the Z axis), and hold the stage 161 still with the other hand (you can also rotate the stage 161 in the direction opposite to the second direction, which will make the accommodating member 17 descend faster). The shell 10 (in this case, the top of the first guide part 102 of the shell 10) begins to push the third guide part 170 to rotate along the higher circumferential slide 1600. When the third guide part 170 rotates to contact the axial slide 1601, it will be blocked by the axial slide 1601. At this time, the base 16 (that is, the top of the axial slide 1601 on the base 16 (the top of the axial slide 1601 is the part of the axial slide 1601 facing the higher circumferential slide 1600). Please refer to the base 16 Figure 7 , the same below) will push the third guide portion 170 to begin descending along the first guide portion 102 and the axial slideway 1601, and then the third guide portion 170 will push the container 17 to begin descending along the axial direction of the base 16 (for example, along the Z-axis direction). When the third guide portion 170 descends to the lower circumferential slideway 1600, the housing 10 (in this case, the bottom end of the first guide portion 102 on the housing 10) will push the third guide portion 170 into the lower circumferential slideway 1600 until the third guide portion 170 stops at the end of the lower circumferential slideway 1600. At this time, the container 17 reaches its lowest position, that is, the earphone 2 also reaches its lowest position. At this time, the movable part 12 can be rotated to drive the cover plate 110 to rotate about the pivot 13 to close the opening 100, preventing dust and foreign matter from entering the interior of the housing 10.

[0109] like Figure 12 As shown, in another embodiment, an earphone box 3 is provided, which includes the earphone box cover opening and closing mechanism 1 in the above embodiment.

[0110] The above is a detailed introduction to the earphone box cover opening and closing mechanism provided in the embodiment of the present application. Those skilled in the art will appreciate that, based on the concepts of the embodiment of the present application, there may be some changes in the specific implementation and scope of application. In summary, the contents of this specification should not be construed as limiting the present application. All equivalent modifications or changes made based on the spirit and technical concepts of the present application shall still be covered by the claims of the present application.
