Detailed Description

[0009] Hereinafter, technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments, but not all the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without inventive work fall within the protection scope of the present disclosure.

[0010] A first embodiment refers to FIGS. 1 to 6.

[0011] This embodiment of the present disclosure provides an earbud system. The earbud system includes a charging case 10 and earbuds. The charging case 10 is configured to accommodate the earbuds. Specifically, the earbud system described in the embodiment of the present disclosure may include at least two earbuds. The earbud system is, for example, a True Wireless Stereo (TWS) earbud system, or other earbuds that need to be charged by the charging case 10, or a neckband wireless earbud system, or a wired earbud system.

[0012] Hereinafter, the earbud system is described by taking a TWS earbud system as an example.

[0013] The TWS earbud system may include a charging case 10 and two earbuds. The charging case 10 is configured to accommodate the earbuds and charge the earbuds after the earbuds are placed in the charging case 10. Optionally, the charging case 10 may include a lid 12 and a body 11 connected to each other, the body 11 is provided with two accommodating grooves 1121, and the number of accommodating grooves 1121 and the number of earbuds may be the same. The accommodating grooves 1121 are configured to accommodate the earbuds. The lid 12 is rotatably / slidably connected to the body 11 and configured to selectively close the accommodating groove 1121. For example, the lid 12 is rotatably connected to the body 11 by a rotating shaft to achieve a flip-type design. For example, the lid 12 can be slid relative to the body 11 by cooperation of a slide rail and a slider, thereby realizing a slide-type design.

[0014] The charging case 10 may charge the earbuds. When the earbuds are accommodated in the accommodating groove 1121, the charging case 10 may be electrically connected to the earbuds to charge the earbuds. For example, charging contacts (shown but not labeled in FIG. 1) may be provided in the accommodating grooves 1121, and charging contacts (not shown) may also be provided accordingly on the earbuds. When the earbud is placed in the accommodating groove 1121, the charging contact of the earbud and the charging contact of the charging case 10 may be in contact to achieve electric connection. Of course, the charging case 10 may wirelessly charge the earbuds. The charging case 10 may be structurally and / or electrically connected to the earbuds by magnetic attraction, and when the earbuds are placed in the accommodating grooves 1121, the charging case 10 magnetically attracts the earbuds.

[0015] The charging case 10 may be provided with a prompting component, such as a display screen or an LED light, which may be configured to prompt information, such as a power level. The charging case 10 may also be provided with a charging interface (not shown), such as a USB interface, a TYPE-C interface, a MIN-USB interface, or a Lighting interface. The two earbuds may be classified into primary and secondary earbuds. The primary earbud may communicate with an external device, for example, through Bluetooth ™< technology. The external device may be a mobile phone, a tablet computer, a smart watch, a laptop computer, or the like. The secondary earbud may communicate with the primary earbud. Data sent by the external device may be sent to the primary earbud, and meanwhile sent to the secondary earbud through the primary earbud, so that the primary earbud and the secondary earbud can receive data synchronously as far as possible.

[0016] Related contents of the charging case 10 in the embodiment of the present disclosure can be further described in detail below.

[0017] Referring to FIGS. 1 to 4, an embodiment of the present disclosure provides a charging case 10 for earbuds, which includes a lid 12 and a body 11. The body 11 is configured to accommodate the earbuds. An accommodating groove 1121 for accommodating the earbuds is provided in the body 11. The shape of the accommodating groove 1121 is configured to fit the shape of the earbuds, so that the accommodating groove 1121 can on one hand accommodate the earbud, and on the other hand restrict movement of the earbud and play a positioning role when the earbud is placed in the accommodating groove 1121.

[0018] The lid 12 is rotatably connected to the body 11 and is rotatable relative to the body 11 between the closed position and the open position to cover the earbuds at the closed position and expose the earbuds at the open position. The lid 12 can cover the earbuds when the earbuds are placed in the body 11, thereby protecting the earbuds, reducing the possibility that the earbuds falls off the body 11, and reducing intrusion of dirt such as dust on the earbuds.

[0019] In some embodiments, the charging case 10 includes a second elastic member (not shown) connecting the body 11 and the lid 12 and configured to drive the lid 12 to rotate to the closed position when the lid 12 is rotated from the open position to the closed position. The second elastic member is, for example, a torsion spring or a spring plate, and is not specifically limited here. When the lid 12 approaches the body 11, the second elastic member can apply a torque that drives the lid 12 to close, so that the lid 12 can automatically close when the lid 12 approaches the body 11. Further, when the lid 12 is in the closed position, the torque applied by the second elastic member can also restrict opening of the lid 12, thereby reducing unexpected opening of the lid 12 caused by movement or vibration, and reducing accidental falling off of the earbuds.

[0020] In some embodiments, the second elastic member is further configured such that the lid 12 has a second transition position relative to the body 11 between the open position and the closed position, elastically drives the lid 12 to rotate to the open position when the lid 12 is rotated from the second transition position to the open position, and elastically drives a support member 115 to rotate to the closed position when the lid 12 is rotated from the second transition position to the closed position. For example, when the body 11 is fixedly placed and the lid 12 is rotated, the lid 12 is rotated relative to the body 11 about a second rotating shaft 120, thereby realizing opening or closing of the lid 12 relative to the body 11. A vector of an elastic force (also referred to as elastic force vector) applied by the second elastic member to the lid 12 can change relative to the position of the second rotating shaft 120 during the opening or closing of the lid 12, thereby causing the direction of the torque applied by the second elastic member to the lid 12 to change, causing the rotation tendency of the lid 12 to change during the opening or closing process, and realizing change of the elastic driving direction described above.

[0021] Specifically, with reference to FIGS. 2 to 3, the second elastic member is located below the second rotating shaft 120, the rotating shaft between the lid 12 and the body 11 is located on the right side of the charging case 10, and the lid 12 can be opened by clockwise rotation and closed by counterclockwise rotation. In the process of shifting the lid 12 from the closed position to the open position, firstly, with reference to FIG. 2, the lid 12 is in the closed position, and the elastic force vector generated by the second elastic member on the lid 12 is located on the right side of the second rotating shaft 120 (refer to the relative position relationship between F1 and the second rotating shaft 120 in FIG. 2), and the lid 12 will be subjected to a counterclockwise torque. The elastic force of the second elastic member prevents the opening of the lid 12, in which case the user can manually apply a clockwise torque to overcome the torque generated by the second elastic member, thereby driving the lid 12 to gradually open. When the lid 12 is gradually opened, the position of the elastic force vector generated by the second elastic member relative to the second rotating shaft 120 changes, and when the lid 12 is opened to the second transition position, the elastic force vector generated by the second elastic member points to the center of the rotating shaft (not shown), that is, the second elastic member does not apply a torque to the lid 12. As the lid 12 continues to open, the elastic force vector generated by the second elastic member shifts to the left side of the second rotating shaft 120 (refer to the relative position relationship between F2 and the second rotating shaft 120 in FIG. 3), and the lid 12 is subjected to a clockwise torque. In this case, even if the user no longer applies the clockwise torque, the second elastic member can apply a clockwise torque to the lid 12, thereby promoting the rotation of the lid 12 to the open position. In other words, after the lid 12 passes the second transition position, the torque applied by the second elastic member can cause the lid 12 to open automatically.

[0022] Referring to FIGS. 2 to 3, in a process of shifting the lid 12 from the open position to the closed position, first, referring to FIG. 3, the lid 12 is in the open position, and at this time, the elastic force vector generated by the second elastic member on the lid 12 is located on the left side of the second rotating shaft 120 (refer to the relative position relationship between F2 and the second rotating shaft 120 in FIG. 3), and the lid 12 will be subjected to a clockwise torque. The elastic force of the second elastic member hinders closing of the lid 12, in which case the user can manually apply a counterclockwise torque to overcome the torque generated by the second elastic member, thereby driving the lid 12 to gradually close. In the process of gradually closing the lid 12, the position of the elastic force vector generated by the second elastic member relative to the second rotating shaft 120 changes, and when the lid 12 is closed to the second transition position, the elastic force vector generated by the second elastic member points to the center of the rotating shaft (not shown), that is, the second elastic member does not apply a torque to the lid 12. As the lid 12 continues to close, the elastic force vector generated by the second elastic member shifts to the right side of the second rotating shaft 120 (refer to the relative position relationship between F1 and the second rotating shaft 120 in FIG. 2), and the lid 12 is subjected to a counterclockwise torque. In this case, even if the user no longer applies the counterclockwise torque, the second elastic member can apply the counterclockwise torque to the lid 12, thereby promoting the rotation of the lid 12 to the closed position. In other words, after the lid 12 passes the second transition position, the torque applied by the second elastic member can cause the lid 12 to automatically close. Moreover, after the lid 12 is closed, the torque applied by the second elastic member can also hinder the opening of the lid 12, thereby preventing unexpected opening of the lid 12.

[0023] In some embodiments, the charging case 10 further includes a support member 115 rotatably provided on the body 11 and rotatable relative to the body 11 between a storage position and a support position to at least partially protrude from the body 11 in the support position and to be stored in the body 11 in the storage position. The lid 12 is configured to cover the support member 115 in the closed position and expose the support member 115 in the open position. The support member 115 and the lid 12 are configured to jointly form a support area in which a mobile terminal is placed at the support position and the open position respectively, so as to jointly support the mobile terminal by the lid 12 and the protruding part of the support member 115 when the mobile terminal is placed in the support area. By providing the support member 115, the charging case 10 can not only serve as a tool for accommodating earbuds, but also serve as a mobile terminal support member 115, which is convenient for users to use. Specifically, when the support member 115 is located at the support position, a first pivot point is formed, and when the lid 12 is located at the open position, a second pivot point is formed, and the first pivot point and the second pivot point jointly support the mobile terminal.

[0024] In some embodiments, with reference to FIGS. 5 and 6, the number of support positions is at least two, the support member 115 can be rotated from the storage position to at least two support positions sequentially, and angles of rotation from the storage position to the different support positions are different. The support member 115 can be held at different support positions by a limit means such as a snap, damping or magnetic attraction, so as to form first pivot points with different positions at different support positions. Further, there are at least two open positions, and the lid 12 can be rotated from the closed position to the at least two open positions sequentially, and angles of rotation from the closed position to the different open positions are different. The lid 12 can be held at the different open positions by a limiting means such as a snap, damping or magnetic attraction, so as to form second pivot points with different positions at different support positions. In the above manner, the support member 115 and the lid 12 can form a first pivot point and a second pivot point with different positions. The first pivot point and the second pivot point with different positions can support the mobile terminal at different angles, thereby adapting to diversified support needs of a user.

[0025] In some embodiments, with reference to FIGS. 1 to 3, the body 11 has a top portion 112 (also referred to as a liner of the body 11), which is provided with an accommodating groove 1121 configured to accommodate the earbuds. The accommodating groove 1121 is located between the support member 115 and the rotating shaft of the lid 12, so that the earbuds can be received by the top portion 112. The lid 12 can close the top portion 112 and cover the support member 115 in the closed position and expose the top portion 112 in the open position. The support member 115 is rotatably connected to the top portion 112. The support member 115 is provided at a certain distance from the accommodating groove 1121, thereby reducing mutual interference between the support member 115 and placement of the earbuds.

[0026] In some embodiments, the top portion 112 is provided with a mounting groove 1122, and the support member 115 is rotatably provided within the mounting groove 1122. When in the support position, the support member 115 is located at least partially outside the mounting groove 1122, thereby cooperating with the lid 12 to form a support area for supporting the mobile terminal. When in the storage position, the support member 115 is accommodated in the mounting groove 1122, thereby avoiding interference between the support member 115 and the lid 12 along with the earbud.

[0027] In some embodiments, with reference to FIGS. 2 and 3, the support member 115 has a free end away from a rotating shaft thereof. When the support member 115 is in the storage position, there is a gripping space between the free end of the support member 115 and a side wall of the accommodating groove 1121. The gripping space is configured to allow a user to rotate the support member 115, thereby driving the support member 115 to rotate from the storage position to the support position.

[0028] In some embodiments, the support member 115 is configured to restrict itself from rotating in a direction from the storage position to the support position when in the support position. Specifically, when the support member 115 is in the support position, the support member 115 is likely to rotate, or even rotate to the storage position under the influence of vibration and movement of the body 11, so that the support member 115 cannot effectively support the mobile terminal. Therefore, the support member 115 is configured to restrict itself from rotating in the direction from the storage position to the support position when in the support position, the support member 115 can be stably held in the support position, thereby improving stability of supporting the mobile terminal.

[0029] Specifically, when the support member 115 is in the support position, the body 11 abuts on the support member 115 in a direction from the support position to the storage position to restrict rotation of the support member 115 in the direction from the support position to the storage position at the support position. For example, the body 11 may be provided with a limiting structure (such as a limiting protruding point and a limiting spring plate). While being rotated by a user, the support member 115 can cross over the limiting structure to the support position by applying a large torque. When the support member 115 is in the support position, the limiting structure abuts against the support member 115, thereby restricting the rotation of the support member 115 and enabling the support member 115 to stably support the mobile terminal. While the support member 115 is rotated to the storage position, the user can apply a force to the support member 115 to rotate the support member 115 to the storage position by overcoming a limiting force of the limiting structure.

[0030] In some embodiments, with further reference to FIG. 4, the charging case 10 includes a first magnetic member 1151 provided on the support member 115 and a second magnetic member 123 provided on the lid 12. The first magnetic member 1151 and the second magnetic member 123 are configured to be magnetically repelled while the support member 115 is in the support position and the lid 12 shifts from the open position to the closed position, and the lid 12 is configured to drive the support member 115 to rotate from the support position to the storage position by the magnetic repulsion of the second magnetic member 123 and the first magnetic member 1151 when the lid 12 is rotated from the open position to the closed position. Thus, the support member 115 located at the support position can automatically rotate to the storage position by the cooperation of the first magnetic member 1151 and the second magnetic member 123 during the closing process of the charging case 10, and the user no longer needs to actively operate, thereby improving the convenience of using the support member 115. The first magnetic member 1151 and the second magnetic member 123 may be disposed facing each other when the support member 115 is in the support position during closing of the lid 12, and facing magnetic poles thereof may be the same. The first magnetic member 1151 and the second magnetic member 123 may not face each other, but a direction of the magnetic field generated by the first magnetic member 1151 at the second magnetic member 123 is opposite to a direction of a magnetic induction line of the second magnetic member 123, thereby generating a repulsive force. A magnetic member refers to an element that can generate a magnetic field, such as a magnet. The magnetic members may have a magnetic field and are capable of generating a magnetic force between each other. In some embodiments, the magnet may include a metal alloy magnet, ferrite, or the like. The metal alloy magnet may include neodymium-iron-boron (NdFeB), samarium-cobalt (SmCo), aluminum-nickel-cobalt (AlNiCo), iron-chromium-cobalt (FeCrCo), aluminum-iron-boron (AlFeB), iron-carbon-aluminum (FeCAl), or the like, or combinations thereof. The ferrite may include barium ferrite, steel ferrite, magnesium-manganese ferrite, lithium-manganese ferrite, the like, or combinations thereof.

[0031] In some embodiments, the support member 115 is configured to restrict itself from rotation in the direction from the storage position to the support position when in the support position. Specifically, the charging case 10 includes a first magnetic attraction member 113, and the first magnetic attraction member 113 is provided on the body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the first magnetic attraction member 113 are configured to magnetically attract each other when the support member 115 is at the support position to hold the support member 115 at the support position. The first magnetic attraction member 113 may be a magnetic member such as a magnet or a soft magnetic material. The soft magnetic material may include a metal material, a metal alloy, a metal oxide material, an amorphous metal material, or the like, such as iron, an iron-silicon alloy, an iron-aluminum alloy, a nickel-iron alloy, an iron-cobalt alloy, low carbon steel, a silicon steel sheet, and ferrite. When the first magnetic attraction member 113 is a magnetic member, the magnetic pole of the first magnetic attraction member 113 may be disposed facing the first magnetic member 1151 when the support member 115 is at the support position. The first magnetic member 1151 and the first magnetic attraction member 113 may not be disposed facing each other, but a direction of the magnetic field generated by the first magnetic attraction member 113 at the first magnetic member 1151 is opposite to a direction of the magnetic induction line of the first magnetic member 1151, thereby generating a repulsive force.

[0032] In an embodiment, the second magnetic member 123 and the first magnetic attraction member 113 are configured to magnetically attract each other when the lid 12 is in the closed position, so that the lid 12 is held in the closed position. The first magnetic attraction member 113 may be a soft magnetic material, and thus generates an attraction force with the second magnetic member 123. The first magnetic attraction member 113 may be a magnetic material such as a magnet. When the lid 12 is at the closed position, the first magnetic attraction member 113 and the second magnetic member 123 are disposed facing each other, and the magnetic poles thereof are opposite to each other, thereby generating the attraction force.

[0033] In some embodiments, the magnetic attraction assembly further includes a second magnetic attraction member 114 provided in the body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetic attraction member 114 are configured to magnetically attract each other when the support member 115 is in the storage position, so that the support member 115 is held in the storage position. By providing the second magnetic attraction member 114, the support member 115 can be stably held in the storage position, thereby reducing unexpected rotation of the support member 115 by the user and reducing collisions between the support member 115 and the body 11, the lid 12, or the like.

[0034] Specifically, when the support member 115 is in the support position, the magnetic attraction force between the first magnetic member 1151 and the first magnetic attraction member 113 is larger than that between the first magnetic member 1151 and the second magnetic attraction member 114. When the support member 115 is in the storage position, the magnetic attraction force between the first magnetic member 1151 and the second magnetic attraction member 114 is larger than that between the first magnetic member 1151 and the first magnetic attraction member 113.

[0035] In summary, the first magnetic member 1151 and the second magnetic member 123 may be magnets because they need to generate repulsive forces; the first magnetic attraction member 113 and the second magnetic attraction member 114 may be magnets or soft magnetic materials because they both generate attraction forces with the first magnetic member 1151 and the second magnetic member 123.

[0036] In some embodiments, the first magnetic member 1151 is embedded within the support member 115 or is provided integrally with the support member 115 as a core when the support member 115 is fabricated. In some embodiments, the second magnetic member 123 is embedded within the lid 12 so as to be invisible on an outer surface of the lid 12. For example, the lid 12 may include an outer lid 121 and an inner lid 122 (or referred to as a lining of the lid 12), and the outer lid 121 and / or the inner lid 122 are rotatably connected to the body 11. The inner lid 122 is provided on an inner side of the outer lid 121. When the lid 12 is in the closed state, the inner lid 122 is provided between the outer lid 121 and the body 11, and the second magnetic member 123 is provided between the outer lid 121 and the inner lid 122. In some embodiments, the first magnetic attraction member 113 is embedded within body 11 so as to be invisible on the outer surface of body 11. For example, the body 11 includes a shell and the top portion 112 (or referred to as a lining of the body 11), the top portion 112 is provided with the accommodating groove 1121 configured to accommodate the earbuds, and the first magnetic attraction member 113 is provided between the shell and the top portion 112.

[0037] In some embodiments, with reference to FIG. 3, the support member 115 is rotatably connected to the body 11 about the first rotating shaft 1150 and has a free end away from the first rotating shaft 1150 and rotated about the first rotating shaft 1150. The free end of the support member 115 approaches or moves away from the second rotating shaft 120 during rotation about the first rotating shaft 1150. The free end is farther away from the second rotating shaft 120 in a support state than in the storage state, and protrudes from the body 11 in the support state to support the mobile terminal. In other words, an opening direction of the support member 115 is opposite to an opening direction of the lid 12, for example, when the lid 12 is rotated clockwise to open, the support member 115 is rotated counterclockwise to open. In this way, when the lid 12 is in the open position and the support member 115 is in the support position, a direction of the pressure of the mobile terminal supported between the lid and the support member 115 thereon tends to hold the lid 12 in the open position and the support member 115 in the support position.

[0038] In some embodiments, with reference to FIG. 3, the support member 115 can rotate about the first rotating shaft 1150 relative to the body 11, the first magnetic attraction member 113 and the second magnetic attraction member 114 are located on both sides of the first rotating shaft 1150, respectively. The body 11 is provided with a first limiting portion 116 and a second limiting portion 117 which are located on two sides of the first rotating shaft 1150, respectively, and correspond to the first magnetic attraction member 113 and the second magnetic attraction member 114, respectively. The first limiting portion 116 is configured to abut against the support member when the support member 115 is rotated from the storage position to the support position, so as to cooperate with the first magnetic attraction member 113 to hold the support member 115 at the support position. The second limiting portion 117 abuts against the support member 115 when the support member is rotated from the support position to the storage position, so as to cooperate with the second magnetic attraction member 114 to hold the support member in the storage position. During the rotation of the support member 115 by the cooperation between the first magnetic member 1151 and the first magnetic attraction member 113 as well as the second magnetic attraction member 114, the support member 115 is continuously subjected to a torque. When the support member 115 rotates to the support position or the storage position, it is necessary to balance the torque acting on the support member 115 to restrict the support member 115 from further rotation. The first limiting portion 116 and the second limiting portion 117 can prevent the further rotation of the support member 115 during the support and storage processes.

[0039] Further, the body 11 is provided with the mounting groove 1122, and the support member 115 is rotatably provided in mounting groove 1122. The support member 115 is at least partially located outside the mounting groove 1122 in the support position and accommodated within the mounting groove 1122 in the storage position. Part of a side wall of the mounting groove 1122 forms the first limiting portion 116, and a bottom wall of the mounting groove forms the second limiting portion 117. When the support member 115 is rotated to the support position, the support member 115 directly abuts against the part of the side wall of the mounting groove 1122 to restrict further rotation of the support member 115, and thus the part of the side wall of the mounting groove 1122 forms the first limiting portion 116. When the support member 115 is rotated to the storage position, the support member 115 abuts against the bottom wall of the mounting groove 1122, thereby restricting further rotation of the support member 115, and thus the bottom wall of the mounting groove 1122 may form the second limiting portion 117.

[0040] In some embodiments, the charging case 10 includes a first elastic member (not shown) connecting the body 11 and the support member 115. The first elastic member is configured such that the support member 115 has a first transition position between the support position and the storage position relative to the body 11, and is configured to elastically drive the support member 115 to rotate to the support position when the support member 115 is rotated from the first transition position to the support position, and elastically drive the support member 115 to rotate to the storage position when the support member 115 is rotated from the first transition position to the storage position. Taking the body 11 fixedly placed and the support member 115 rotated as an example, the support member 115 rotates about the first rotating shaft 1150 relative to the body 11, thereby enabling support or storage of the support member 115 relative to the body 11. During the opening or closing of the support member 115, the vector of the elastic force applied by the first elastic member to the support member 115 can change relative to the position of the first rotating shaft 1150, thereby changing the direction of the torque applied by the first elastic member to the support member 115, changing the rotation tendency of the support member 115 during opening or closing thereof, and realizing the change of the elastic driving direction.

[0041] Specifically, for example, the first elastic member is located below the first rotating shaft 1150 and at the left end of the support member 115 in the storage position, the support member 115 may be moved to the storage position by clockwise rotation and to the support position by counterclockwise rotation. During the shift of the support member 115 from the storage position to the support position, the support member 115 is initially in the storage position, at which time the vector of the elastic force applied by the first elastic member to the support member 115 is located on the left side of the first rotating shaft 1150, and the torque acting on the support member 115 causes the support member 115 to tend to rotate clockwise. The elastic force of the first elastic member may hinder the opening of the support member 115, in which case the user may manually apply a counterclockwise torque to overcome the torque generated by the first elastic member, thereby driving the support member 115 to gradually open to the support position. During the gradual opening of the support member 115, the position of the elastic force vector generated by the first elastic member changes relative to the first rotating shaft 1150. When the support member 115 is opened to the first transition position, the elastic force vector generated by the first elastic member points to the center of the rotating shaft, that is, the first elastic member does not apply a rotation torque to the support member 115. As the support member 115 continues to open, the elastic force vector generated by the first elastic member shifts to the right side of the first rotating shaft 1150, and the support member 115 is subjected to a counterclockwise torque. In this case, even if the user no longer applies the counterclockwise torque, the first elastic member can apply a counterclockwise torque to the support member 115, thereby promoting the rotation of the support member 115 to the support position. In other words, after the support member 115 passes the first transition position, the torque applied by the first elastic member can promote the support member 115 to automatically rotate to the support position.

[0042] During the shift of the support member 115 from the support position to the storage position, first, the support member 115 is in the support position, at which time the vector of the elastic force generated by the first elastic member on the support member 115 is located on the right side of the first rotating shaft 1150, and the support member 115 is subjected to a counterclockwise torque. The elastic force of the first elastic member may hinder the storage of the support member 115, in which case the user may manually apply a clockwise torque to overcome the torque generated by the first elastic member, thereby driving the support member 115 to be gradually stored. During the gradual storage of the support member 115, the position of the elastic force vector generated by the first elastic member changes relative to the first rotating shaft 1150. When the support member 115 is stored to the first transition position, the elastic force vector generated by the first elastic member points to the center of the rotating shaft, that is, the first elastic member does not apply a torque to the support member 115. As the support member 115 continues to be stored, the elastic force vector generated by the first elastic member shifts to the left side of the first rotating shaft 1150, causing the support member 115 to be subjected to a clockwise torque. In this case, even if the user no longer applies the clockwise torque, the first elastic member can apply a clockwise torque to the support member 115, thereby promoting the rotation of the support member 115 to the storage position. In other words, after the support member 115 passes the first transition position, the torque applied by the first elastic member can promote the support member 115 to be automatically stored.

[0043] In some embodiments, with reference to FIG. 4, the charging case 10 includes a first magnetic member 1151 provided on the support member 115 and a second magnetic member 123 provided on the lid 12. The first magnetic member 1151 is closer to the second rotating shaft 120 than the second magnetic member 123, so that the second magnetic member 123 can apply a repulsive force to the first magnetic member 1151 at a side of the support position away from the storage position of the support member 115, and can drive the support member 115 to rotate from the support position to the storage position. The first magnetic member 1151 and the second magnetic member 123 are configured to magnetically repel each other when the support member 115 is in the support position and the lid 12 is in the closed position. When the lid 12 is rotated from the open position to the closed position, the second magnetic member 123 and the first magnetic member 1151 are magnetically repelled to drive the support member 115 to rotate from the support position to the storage position. Thus, the support member 115 located at the support position can automatically rotate to the storage position by the cooperation of the first magnetic member 1151 and the second magnetic member 123 during the closing process of the charging case 10, and the user no longer needs to actively operate, thereby improving the convenience of using the support member 115. The first magnetic member 1151 and the second magnetic member 123 may be disposed facing each other during closing of the lid 12 when the support member 115 is in the support position, and the facing magnetic poles are the same. The first magnetic member 1151 and the second magnetic member 123 may not be disposed facing each other, but a direction of the magnetic field generated by the first magnetic member 1151 at the second magnetic member 123 is opposite to a direction of the magnetic induction line of the second magnetic member 123, thereby generating a repulsive force.

[0044] In some embodiments, the support member 115 is configured to restrict its rotation in the direction from the storage position to the support position when in the support position. Specifically, the charging case 10 includes a first magnetic attraction member 113 provided in the body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the first magnetic attraction member 113 are configured to magnetically attract each other when the support member 115 is in the support position, so that the support member 115 is held in the support position. The first magnetic member 1151 is closer to the second rotating shaft 120 than the first magnetic attraction member 113, enabling the first magnetic attraction member 113 to generate an attraction force with the first magnetic member 1151 on the side of the support position of the support member 115 away from the storage position, thereby holding the support member 115 at the support position.

[0045] In some embodiments, when in the closed position, the lid 12 closes the body 11 in a preset direction, the second magnetic member 123 and the first magnetic attraction member 113 are spaced apart from each other in the preset direction and magnetically attract each other to hold the lid 12 in the closed position. The preset direction may be a thickness direction of the charging case 10.

[0046] On the basis of the above-described embodiment, the charging case 10 includes a second magnetic attraction member 114 provided in the body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetic attraction member 114 are configured to magnetically attract each other when the support member 115 is in the storage position, so that the support member 115 is held in the storage position. The second magnetic attraction member 114 can cause the support member 115 to be stably held in the storage position, thereby reducing unexpected rotation of the support member 115 by the user and reducing collisions between the support member 115 and the body 11, the lid 12, or the like.

[0047] A second embodiment refers to FIGS. 7 to 17.

[0048] This embodiment of the present disclosure provides an earbud system. The earbud system includes a charging case 10 and earbuds. The charging case 10 is configured to accommodate the earbuds and charge the earbuds after the earbuds are placed in the charging case 10. Optionally, the charging case 10 may include a lid 11 and a body 12 connected to each other, the body 12 is provided with two accommodating grooves 122, and the number of the accommodating grooves 122 and the number of earbuds may be the same. The accommodating grooves 122 are configured to accommodate the earbuds. The lid 11 is rotatably / slidably connected to the body 12 for selectively closing the accommodating grooves 122. For example, the lid 11 is rotatably connected to the body 12 by a rotating shaft to achieve a flip-type design. For example, the lid 11 can be slid relative to the body 12 by the cooperation of a slide rail and a slider, thereby realizing a slide-type design.

[0049] The charging case 10 may charge the earbuds. When the earbuds are accommodated in the accommodating grooves 122, the charging case 10 may be electrically connected to the earbuds to charge the earbuds. For example, charging contacts (shown but not labeled in FIG. 7) may be provided in the accommodating grooves 122, and charging contacts (not shown) may also be provided accordingly on the earbuds. When the earbuds are placed in the accommodating grooves 122, the charging contacts of the earbuds and the charging contacts of the charging case 10 may be in contact to achieve electric connection. Of course, the charging case 10 may wirelessly charge the earbuds. The charging case 10 may be structurally and / or electrically connected to the earbuds by magnetic attraction, and when the earbuds are placed in the accommodating grooves 122, the charging case 10 magnetically attracts the earbuds. The two earbuds may be divided into primary and secondary earbuds. The primary earbud may communicate with an external device, for example, through Bluetooth ™< technology. The external device may be a mobile phone, a tablet computer, a smart watch, a laptop computer, or the like. The secondary earbud may communicate with the primary earbud. Data sent by the external device may be sent to the primary earbud, and meanwhile to the secondary earbud through the primary earbud, so that the primary earbud and the secondary earbud can receive data synchronously as far as possible.

[0050] Related contents of the charging case 10 in the embodiment of the present disclosure can be further described in detail below.

[0051] Referring to FIG. 7, the embodiment of the present disclosure provides the charging case 10 for the earbuds. The charging case 10 includes the body 12, the lid 11, and a support assembly 124. The body 12 is configured to accommodate the earbuds, and the accommodating grooves 122 configured to accommodate the earbuds are provided in the body 12. The shape of the accommodating groove 122 is configured to fit the shape of an earbud, so that the accommodating groove 122 can on one hand accommodate the earbud, and on the other hand restrict movement of the earbud and play a positioning role when the earbud is placed in the accommodating groove 122. The body 12 may be further provided with components such as a battery and a power control board for managing input and output of power to charge the earbuds.

[0052] The lid 11 is rotatably connected to the body 12 and is rotatable relative to the body 12 between the closed position and the open position to cover the earbuds at the closed position and expose the earbuds at the open position. The lid 11 can cover the earbuds when the earbuds are placed in the body 12, thereby protecting the earbuds, reducing the possibility that the earbuds falls off the body 12, and reducing intrusion of dirt such as dust on the earbuds.

[0053] With reference to FIGS. 8 and 11 to 13, the support assembly 124 includes a support member 1241 and a first elastic member 125. The support member 1241 is rotatably provided on the body 12 and rotatable relative to the body 12 between a storage position and a support position to at least partially protrude from the body 12 in the support position. A protruding part of the support member 1241 and the lid 11 are spaced apart from each other and together serve to support the mobile terminal when the support member 1241 is in the support position and the lid 11 is in the open position. The support member 1241 is stored in the body 12 when in the storage position, thereby avoiding interference between the support member 1241 and the lid 11 or the earbuds, and reducing the space occupied by the support member 1241. The first elastic member 125 connects the support member 1241 and the body 12 to elastically constrain the support member 1241 in the storage position or the support position. In other words, the first elastic member 125 can provide a force for holding the support member 1241 in the storage position or the support position, and a force for automatically rotating the support member 1241 to the storage position or the support position. A first pivot point is formed when the support member 1241 is in the support position, a second pivot point is formed when the lid 11 is in the open position, and the first pivot point and the second pivot point together support the mobile terminal. Optionally, the support member 1241 may be engaged with the body 12 and have an intermediate support position during rotation. A first pivot point at different positions may be formed when the support member 1241 is in the intermediate support position. The lid 11 may be engaged with the body 12 to form an intermediate open position during opening. Second pivot points with different positions may be formed when the lid is at the intermediate open position. Through the foregoing manner, the positions of the first pivot point and the second pivot point can be changed to support the mobile terminal at different angles.

[0054] In some embodiments, with reference to FIG. 8, the body 12 is provided with a mounting groove 123, and the lid 11 covers the mounting groove 123 in the closed position and exposes the mounting groove 123 in the open position. The support member 1241 is rotatably provided in the mounting groove 123. In the support position, at least part of the support member 1241 protrudes outside the mounting groove 123 to cooperate with the lid 11 to support the mobile terminal. In the storage position, the support member 1241 is located within the mounting groove 123 to hide and store the support member 1241 and reduce the volume occupied by the support member 1241 protruding from the surface of the body 12.

[0055] Specifically, the body 12 includes a shell and a top wall (shown but not labeled in FIG. 8). The top wall is provided with the aforementioned mounting groove 123, and the support member 1241 is rotatably provided in the mounting groove 123. The support member 1241 is at least partially located outside the mounting groove 123 in the support position, and is accommodated in the mounting groove 123 in the storage position. Optionally, the support member 1241 has a support portion 1243 away from a rotation axis thereof. When the support member 1241 is in the storage position, a gripping space (shown but not labeled in FIG. 9) between the support portion 1243 and the side wall of the mounting groove 123. The gripping space is configured to allow a user to rotate the support member 1241, thereby driving the support member 1241 to rotate from the storage position to the support position.

[0056] The charging case 10 further includes a second elastic member 126 connecting the body 12 and the lid 11. The second elastic member 126 is configured such that the lid 11 has a second transition position between the open position and the closed position relative to the body 12, and configured to elastically drive the lid 11 to rotate to the open position when the lid 11 is rotated from the second transition position to the open position, and elastically drive the lid 11 to rotate to the closed position when the lid 11 rotates from the second transition position to the closed position.

[0057] Taking the body 12 fixedly placed and the lid 11 rotated as an example, the lid 11 is rotated relative to the body 12 about a first rotation axis 111, thereby realizing the opening or closing of the lid 11 relative to the body 12. During the opening or closing of the lid 11, the vector of the elastic force applied by the second elastic member 126 to the lid 11 may change relative to the position of the first rotation axis 111. This results in a change in the direction of the torque applied by the second elastic member 126 to the lid 11, thereby changing the rotation tendency of the lid 11 during the opening or closing thereof, and realizing change of the elastic driving direction.

[0058] Specifically, with reference to FIGS. 9 and 10, the second elastic member 126 is located below the first rotation axis 111, the rotation axis of the lid 11 and the body 12 are located on the right side of the charging case 10, and the lid 11 can be opened by clockwise rotation, and can be closed by counterclockwise rotation. In the process of rotating the lid 11 from the closed position to the open position, first, the lid 11 is in the closed position, at which time the elastic force vector generated by the second elastic member 126 on the lid 11 is located on the right side of the first rotation axis 111 (schematically shown with reference to F1 in FIG. 9), and the lid 11 may be subjected to a counterclockwise torque. The elastic force of the second elastic member 126 may hinder the opening of the lid 11, in which case the user may manually apply a clockwise torque to overcome the torque applied by the second elastic member 126, thereby driving the lid 11 to gradually open. During the gradual opening of the lid 11, the position of the elastic force vector generated by the second elastic member 126 changes relative to the first rotation axis 111. When the lid 11 is opened to the second transition position, the elastic force vector generated by the second elastic member 126 points to the center of the rotation axis (not shown), that is, the second elastic member 126 does not apply a torque to the lid 11. As the lid 11 continues to open, the elastic force vector generated by the second elastic member 126 shifts to the left side of the first rotation axis 111 (see F2 in FIG. 10), and the lid 11 is subjected to a clockwise torque. In this case, even if the user no longer applies the clockwise torque, the second elastic member 126 can apply the clockwise torque to the lid 11, thereby promoting the rotation of the lid 11 to the open position. In other words, after the lid 11 passes the second transition position, the torque applied by the second elastic member 126 can cause the lid 11 to open automatically.

[0059] In the process of transitioning the lid 11 from the open position to the closed position, first, with reference to FIG. 9, the lid 11 is in the open position, and at this time, the elastic force vector generated by the second elastic member 126 on the lid 11 is located on the left side of the first rotation axis 111 (refer to the relative position relationship between F2 and the first rotation axis 111 in FIG. 9), and the lid 11 may be subjected to a clockwise torque. The elastic force of the second elastic member 126 may hinder the closing of the lid 11, in which case the user may manually apply a counterclockwise torque to overcome the torque applied by the second elastic member 126, thereby driving the lid 11 to gradually close. When the lid 11 is gradually closed, the position of the elastic force vector generated by the second elastic member 126 changes relative to the first rotation axis 111, and when the lid 11 covers the second transition position, the elastic force vector generated by the second elastic member 126 points to the center of the rotation axis (not shown), that is, the second elastic member 126 does not apply a torque to the lid 11. As the lid 11 continues to close, the elastic force vector generated by the second elastic member 126 shifts to the right side of the first rotation axis 111 (see the relative position relationship between F1 and the first rotation axis 111 in FIG. 8), and the lid 11 is subjected to a counterclockwise torque. In this case, even if the user no longer applies the counterclockwise torque, the second elastic member 126 can apply the counterclockwise torque to the lid 11, thereby promoting the rotation of the lid 11 to the closed position. In other words, after the lid 11 passes the second transition position, the torque applied by the second elastic member 126 can promote the lid 11 to automatically close. Moreover, after the lid 11 is closed, the torque applied by the second elastic member 126 can also hinder the opening of the lid 11, thereby preventing unexpected opening of the lid 11.

[0060] In some embodiments, the first elastic member 125 is configured to elastically constrain the support member 1241 in the storage position when the support member 1241 is in the storage position and elastically constrain the support member 1241 in the support position when the support member 1241 is in the support position. Specifically, since the support member 1241 is rotatably connected to the body 12 and has a rotation axis, the first elastic member 125 may be configured to change the position as the support member 1241 is rotated, thereby causing a change in a vector direction of the elastic force. For example, when the body 12 is in the storage position, the position relationship between the vector direction of the first elastic member 125 and the rotation axis may be set, so that the support member 1241 is subjected to a torque that prevents the same from being opened from the storage position. While the user opens the support member 1241 by applying an external force, the position of the first elastic member 125 may also change accordingly. When the support member 1241 is in the support position, the position relationship between the vector direction of the first elastic member 125 and the rotation axis may be set, so that the support member 1241 is subjected to a torque that prevents the same from being stored from the support position.

[0061] In some embodiments, with reference to FIGS. 11 to 13, the first elastic member 125 is configured such that the support member 1241 has a first transition position (with reference to FIG. 12) between the support position (with reference to FIG. 13) and the storage position (with reference to FIG. 5) relative to the body 12. When the support member 1241 is rotated from the first transition position to the support position, the first elastic member 125 elastically drives the support member 1241 to rotate to the support position and elastically restrains the support member 1241 in the support position. When the support member 1241 is rotated from the first transition position to the storage position, the first elastic member 125 elastically drives the support member 1241 to rotate to the storage position and elastically restrains the support member 1241 in the storage position. That is, before and after the support member 1241 is in the first transition position, the direction of the torque applied by the first elastic member 125 to the support member 1241 changes.

[0062] Taking the body 12 fixedly placed and the support member 1241 rotated as an example, the support member 1241 is rotated relative to the body 12 about a second rotation axis 127 (or preset rotation axis), thereby realizing the support or storage of the support member 1241 relative to body 12. The position of the vector of the elastic force applied by the first elastic member 125 to the support member 1241 may change relative to the second rotation axis 127 during the opening or closing of the support member 1241, thereby causing the direction of the torque applied by the first elastic member 125 to the support member 1241 to change, causing the rotation tendency of the support member 1241 to change during the opening or closing of the support member 1241, and realizing change in the above-described elastic driving direction.

[0063] In some embodiments, the support member 1241 has a rotating portion provided corresponding to the preset rotating axis, and a support portion 1243 and a connecting portion 1244 provided respectively at two ends of the rotating portion and rotating about the preset rotating axis, which are respectively located on two sides of the preset rotating axis. The support portion 1243 protrudes from the body 12 when the support member 1241 is in a support state to support the mobile terminal in cooperation with the lid 11. The connecting portion 1244 can be connected to the first elastic member 125 so as to drive the support member 1241 to rotate.

[0064] In some embodiments, the support member 1241 is rotatably provided at the body 12 about the preset second rotation axis 127, a first end of the first elastic member 125 is connected to the connecting portion 1244 of the support member 1241, and the connecting portion 1244 is spaced apart from the preset rotation axis. A second end of the first elastic member 125 is connected to the body 12. Optionally, a direction of the elastic force generated by the first elastic member 125 is parallel to a direction of a line connecting the first end and the second end of the first elastic member 125. When the support member 1241 is in the first transition position, a line connecting the connecting portion 1244 and the second end of the first elastic member 125 has an intersection point with the preset rotation axis. In other words, the direction of the elastic force of the first elastic member 125 points to the preset rotation axis, at which time the elastic force of the first elastic member 125 cannot apply a rotation torque to the support member 1241, and the support member 1241 is in the first transition position. When the support member 1241 is in the storage position or the support position, the line connecting the connecting portion 1244 and the second end of the first elastic member 125 and the rotation axis are skew lines. As a result, the elastic force of the first elastic member 125 can be spatially spaced apart from the preset rotation axis, enabling the elastic force of the first elastic member 125 to be a torque that drives the support member 1241 to rotate or hold the support member 1241 in the support position or the storage position.

[0065] In some embodiments, with reference to FIG. 11, when the support member 1241 is in the storage position, the preset rotation axis is located on one side of the line connecting the connecting portion 1244 and the second end of the first elastic member 125, and the torque applied to the support member 1241 causes the support member 1241 to tend to rotate in a first direction. When the support member 1241 is in the support position, with reference to FIG. 13, the rotation axis is located on the other side of the line connecting the connecting portion 1244 and the second end of the first elastic member 125, and the torque applied to the support member 1241 causes the support member 1241 to have a tendency to rotate in a second direction. The first direction is opposite to the second direction, the first direction is a direction of rotation from the support position to the storage direction, and the second direction is a direction of rotation from the storage position to the support position.

[0066] In some embodiments, with reference to FIGS. 11 to 13, when the support member 1241 is between the storage position and the first transition position, the preset rotation axis is located on one side of the line connecting the connecting portion 1244 and the second end of the first elastic member 125, and the torque applied to support member 1241 causes the support member 1241 to have a tendency to rotate in the first direction (schematically shown with reference to F in FIG. 11). When the support member 1241 is between the support position and the first transition position, the rotation axis is located on the other side of the line connecting the connecting portion 1244 and the second end of the first elastic member 125, and the torque applied to the support member 1241 causes the support member 1241 to have a tendency to rotate in the second direction (schematically shown with reference to F in FIG. 13).

[0067] In some embodiments, an elastic deformation quantity of the first elastic member 125 when the support 1241 is in the first transition position is larger than an elastic deformation quantity when the support 1241 is in the support position or the storage position. When the support member 1241 is rotated from the first transition position to the support position or the storage position, the first elastic member 125 elastically drives the support member 1241 to rotate to the support position or the storage position correspondingly by elastic recovery. In other words, when the first elastic member 125 is in a compressed state, a compression amount of the first elastic member 125 is maximum when the support member 1241 is in the first transition position. Thus, after the support member 1241 passes the first transition position, the elastic force of the first elastic member 125 is large, and the support member 1241 can be driven more quickly to rotate to the storage position or the support position.

[0068] In some embodiments, the first elastic member 125 may be a spring. The above embodiment is described below by taking the first elastic member 125 as a spring for example. Specifically, the first elastic member 125 is located below the second rotation axis 127 and approaches the left end of the support member 1241 in the storage position, the support member 1241 can be rotated to the storage position by clockwise rotation and can be rotated to the support position by counterclockwise rotation. In the process of shifting the support member 1241 from the storage position to the support position, first, with reference to FIG. 11, the support member 1241 is in the storage position, at which time the elastic force vector generated by the first elastic member 125 on the lid 11 is located on the left side of the second rotation axis 127 (schematically shown with reference to F in FIG. 11), and the torque applied to the support member 1241 causes the support member 1241 to rotate clockwise. The elastic force of the first elastic member may hinder the opening of the support member 1241, in which case the user may manually apply a counterclockwise torque to overcome the torque generated by the first elastic member 125, thereby driving the support member 1241 to gradually open to the support position. While the support member 1241 is gradually opened, the position of the elastic force vector generated by the first elastic member 125 changes relative to the second rotation axis 127. Referring to FIG. 12, when the support member 1241 is opened to the first transition position, the elastic force vector generated by the first elastic member 125 points to the center of the rotation axis, that is, the first elastic member 125 does not apply a rotation torque to the support member 1241. Referring to FIG. 13, as the support member 1241 continues to open, the elastic force vector generated by the first elastic member 125 shifts to the right side of the second rotation axis 127 (schematically shown with reference to F in FIG. 13), and the support member 1241 is subjected to a counterclockwise torque. In this case, even if the user no longer applies the counterclockwise torque, the first elastic member 125 can apply a counterclockwise torque to the support member 1241, thereby promoting the rotation of the support member 1241 to the support position. In other words, after the support member 1241 passes the first transition position, the torque applied by the first elastic member 125 can promote the support member 1241 to automatically rotate toward the support position.

[0069] In the process of shifting the support member 1241 from the support position to the storage position, first, with reference to FIG. 13, the support member 1241 is in the support position. At this time, the elastic force vector generated by the first elastic member 125 on the support member 1241 is located on the right side of the second rotation axis 127 (schematically shown with reference to F in FIG. 13), and the support member 1241 is subjected to a counterclockwise torque. The elastic force of the first elastic member 125 may hinder the storage of the support member 1241, in which case the user may manually apply a clockwise torque to overcome the torque generated by the first elastic member 125, thereby driving the support member 1241 to be gradually stored. In the process of gradually storing the support member 1241, the position of the elastic force vector generated by the first elastic member 125 changes relative to the second rotation axis 127. When the support member 1241 is stored to the first transition position, the elastic force vector generated by the first elastic member 125 points to the center of the rotation axis with reference to FIG. 12, that is, the first elastic member 125 does not apply a torque to the support member 1241. As the support member 1241 continues to be stored, the elastic force vector generated by the first elastic member 125 shifts to the left side of the second rotation axis 127 with reference to FIG. 11 (schematically shown with reference to F in FIG. 11), and the support member 1241 is subjected to a clockwise torque. In this case, even if the user no longer applies the clockwise torque, the first elastic member 125 can apply a clockwise torque to the support member 1241, thereby promoting the rotation of the support member 1241 to the storage position. In other words, after the support member 1241 passes the first transition position, the torque applied by the first elastic member 125 can promote the support member 1241 to be automatically stored.

[0070] In some embodiments, the support member 1241 is further provided with a limiting portion 1242 capable of abutting against the body 12 with the support member 1241 in the support position, thereby restricting further rotation of the support 1241 and holding the support member 1241 in the support position.

[0071] Referring to FIGS. 14 to 17, in other embodiments, the first elastic member 125 may be a spring plate. The above embodiment is described below by taking a spring plate as an example of the first elastic member 125. The support member 1241 is provided with a limiting portion 1242 that is spaced apart from the preset rotation axis and rotated about the preset rotation axis. The first elastic member 125 is fixed to the body 12 and includes a fixed segment 1252 and an elastically movable segment 1251 that is elastically movable relative to the body 12. The elastically movable segment 1251 includes a protruding portion 12511 arched toward the limiting portion 1242 and two connecting portions 12512 connected to two sides of the protruding portion 12511. The first elastically member 125 further includes a fixed segment 1252 connected to one end of each of the two elastically movable segments 1251, and the fixed segment 1252 is fixedly connected to the body 12.

[0072] When the support member 1241 is rotated, the limiting portion 1242 can move between the two connecting portions 12512 by crossing the protruding portion 12511. While the limiting portion 1242 crosses the protruding portion 12511 from the connecting portion 12512, the elastically movable portion 1251 may be elastically deformed. The elastic force generated by the elastic deformation can act on the support member 1241 through the limiting portion 1242, so that the support member 1241 can be subjected to the rotation torque. The limiting portion 1242 elastically abuts against the protruding portion 12511 when the support member 1241 is in the first transition position, and elastically abuts against the two connecting portions 12512 when the support member 1241 is in the storage position and the support position.

[0073] In some embodiments, there are two elastically movable segments 1251 respectively located at two ends of the support member 1241 and facing each other. There are two limiting portions 1242 extending along the direction of the preset rotation axis, and the two elastically movable segments 1251 are configured to abut against the two limiting portions 1242 respectively, which can distribute the force applied by the first elastic member 125 to the support member 1241 at two ends of the support member 1241 evenly, thereby reducing generation of unnecessary rotation torque.

[0074] In some embodiments, the protruding portion 12511 is provided in an arc-shaped arch, and the limiting portion 1242 has an arc-shaped surface configured to abut against the elastically movable segment 1251. Thus, while the limiting portion 1242 crosses the protruding portion 12511 from the connecting portion 12512, the limiting portion 1242 continuously abuts against the protruding portion 12511. Additionally, the direction of the elastic force applied by the protruding portion 12511 to the limiting portion 1242 can gradually decrease rather than change abruptly, thereby enabling smoother rotation of the support member 1241.

[0075] With reference to FIGS. 15 to 17, the above-described embodiments will be described exemplarily: the support member 1241 is in the storage position when the limiting portion 1242 is located below the protruding portion 12511, and the support member 1241 is in the support position when the limiting portion 1242 is located above the protruding portion 12511.

[0076] In the process of opening the support member 1241 from the storage position to the support position, the support member 1241 is first in the storage position with reference to FIG. 15. When the support member 1241 is in the storage position, the limiting portion 1242 is located below the protruding portion 12511. At this time, the protruding portion 12511 abuts against the lower connecting portion 12512. When the support member 1241 tends to rotate toward the support position, the limiting portion 1242 abuts against the protruding portion 12511, the elastically movable segment 1251 is elastically deformed under the push of the limiting portion 1242 and thus generates an elastic force on the limiting portion 1242, with a direction of a component in the movement direction of the limiting portion 1242 opposite to the movement direction. The elastic force can produce a torque that prevents rotation of the support member 1241, thereby restricting the support member 1241 from being rotated toward the support position. The user can manually apply a rotation torque to the support member 1241 to overcome the elastic force of the protruding portion 12511 to the limiting portion 1242, thereby causing the limiting portion 1242 to gradually move upward over the protruding portion 12511 and the support member 1241 to gradually rotate from the storage position to the support position. During the rotation, a contact position between the limiting portion 1242 and the protruding portion 12511 constantly changes, and since the limiting portion 1242 and the protruding portion 12511 are provided in an arc shape, an acting force therebetween is perpendicular to the tangent line of the contact point. The angle between an elastic force direction of the protruding portion 12511 with respect to the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually increases, and the elastic force direction gradually becomes parallel to the preset rotation axis of the support member 1241. During the above-described process, the component of the elastic force of the protruding portion 12511 in the movement direction of the limiting portion 1242 also gradually decreases, that is, the torque that hinders the rotation of the support member 1241 gradually decreases. When the direction of the elastic force of the protruding portion 12511 with respect to the limiting portion 1242 is perpendicular to the movement direction of the limiting portion 1242, the component of the elastic force of the protruding portion 12511 in the movement direction of the limiting portion 1242 is 0. At this time, the support member 1241 is rotated to the first transition position, and with reference to FIG. 16, the protruding portion 12511 no longer restricts the rotation of the support member 1241. As the support member 1241 continues to rotate, the limiting portion 1242 moves upward, and the contact position between the protruding portion 12511 and the limiting portion 1242 continues to change. After crossing the first transition position, the angle between the elastic force direction of the protruding portion 12511 with respect to the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually decreases, a direction of the elastic force component in the movement direction of the limiting portion 1242 is the same as the movement direction of the limiting portion 1242, that is, the elastic force of the protruding portion 12511 with respect to the limiting portion 1242 can generate a rotation torque that promotes the support member 1241 to rotate to the support position. Even when the user no longer applies the torque, the elastic force of the protruding portion 12511 can push the limiting portion 1242 to move upward. The support member 1241 can automatically rotate to the support position under the torque of the first elastic member 125 (see FIG. 17).

[0077] In the process of closing the support member 1241 from the support position to the storage position, the support member 1241 is first in the support position with reference to in FIG. 17, at which time the limiting portion 1242 is located above the protruding portion 12511. At this time, the protruding portion 12511 abuts on the upper connecting portion 12512, and when the support member 1241 tends to rotate toward the storage position, the limiting portion 1242 abuts on the protruding portion 12511, and the elastically movable segment 1251 is elastically deformed under the push of the limiting portion 1242, thereby generating an elastic force on the limiting portion 1242, with a direction of a component in the movement direction of the limiting portion 1242 opposite to the movement direction of the limiting portion 1242, which can generate a torque that prevents the rotation of the support member 1241 to restrict the rotation of the support member 1241 to the storage position. The user can manually apply a rotation torque to the support member 1241 to overcome the elastic force of the protruding portion 12511 to the limiting portion 1242, thereby causing the limiting portion 1242 to gradually move downward over the protruding portion 12511, and the support member 1241 is also gradually rotated from the support position to the storage position. During the rotation, a contact position between the limiting portion 1242 and the protruding portion 12511 constantly changes, and since the limiting portion 1242 and the protruding portion 12511 are provided in an arc shape, an acting force therebetween is perpendicular to a tangent line of the contact point. An angle between the elastic force direction of the protruding portion 12511 with respect to the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually increases, and the elastic force direction gradually becomes parallel to the preset rotation axis of the support member 1241. During the above-described process, the component of the elastic force of the protruding portion 12511 in the movement direction of the limiting portion 1242 also gradually decreases, that is, the torque that hinders the rotation of the support member 1241 gradually decreases. When the elastic force direction of the protruding portion 12511 with respect to the limiting portion 1242 is perpendicular to the movement direction of the limiting portion 1242, the component of the elastic force of the protruding portion 12511 in the movement direction of the limiting portion 1242 is 0. At this time, the support member 1241 is rotated to the first transition position. With reference to FIG. 16, the protruding portion 12511 no longer restricts the rotation of the support member 1241. As the support member 1241 continues to rotate, the limiting portion 1242 moves downward, and the contact position between the protruding portion 12511 and the limiting portion 1242 continues to change. After crossing the first transition position, the angle between the elastic force direction of the protruding portion 12511 with respect to the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually decreases, and a direction of the elastic force component in the movement direction of the limiting portion 1242 is the same as the movement direction of the limiting portion 1242, that is, the elastic force of the protruding portion 12511 to the limiting portion 1242 can generate a rotation torque that promotes the support member 1241 to rotate to the storage position. Even when the user no longer applies the torque, the elastic force of the protruding portion 12511 can push the limiting portion 1242 to move downward. The support member 1241 can automatically rotate to the storage position under the torque of the first elastic member 125 (see FIG. 15).
