[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The first embodiment is shown in FIG. 1 to FIG. 6 .

[0028] An embodiment of the present application provides an earphone system. The earphone system includes a charging box 10 and earphones, and the charging box 10 is used to accommodate the earphones. Specifically, the earphone system described in the embodiment of the present application may include at least two earphones. The earphone system is, for example, a TWS (true wireless) earphone system, or other earphones that need to be charged through the charging box 10, or a neck-hanging wireless earphone system, or a wired earphone system, etc.

[0029] The following description takes a TWS headset system as an example.

[0030] The TWS earphone system may include a charging box 10 and two earphones. The charging box 10 is used to accommodate the earphones and charge the earphones after they are placed in the charging box 10. Optionally, the charging box 10 may include a box cover 12 and a box body 11 that are connected to each other. The box body 11 is provided with two receiving slots 1121. The number of receiving slots 1121 and the number of earphones may be the same. The receiving slots 1121 are used to accommodate earphones. The box cover 12 is rotatably / slidably connected to the box body 11 for selectively covering the receiving slots 1121. For example, the box cover 12 is rotatably connected to the box body 11 via a rotating shaft to realize a flip-type design. For example, the box cover 12 can slide relative to the box body 11 through the cooperation of a slide rail and a slider, thereby realizing a sliding design.

[0031] The charging box 10 can charge the earphones. When the earphones are accommodated in the accommodating slot 1121, the earphones can be electrically connected to charge the earphones. For example, charging contacts (shown in Figure 1 but not marked) can be provided in the accommodating slot 1121, and charging contacts (not shown) are also provided on the earphones accordingly. When the earphones are placed in the accommodating slot 1121, the charging contacts of the earphones and the charging contacts of the charging box 10 can be in contact to achieve electrical connection. Of course, the charging box 10 can also be charged wirelessly with the earphones. The charging box 10 can be structurally and / or electrically connected to the earphones by magnetic attraction. When the earphones are placed in the accommodating slot 1121, the charging box 10 and the earphones are magnetically attracted to each other.

[0032] The charging box 10 may be provided with a prompt component, such as a display screen or an LED light, which may be used to prompt corresponding information, such as the power level. The charging box 10 may also be provided with a charging interface (not shown), such as a USB interface, a TYPE-C interface, a MIN-USB interface, and a Lighting interface. The two earphones may be divided into a main earphone and a secondary earphone. The main earphone may be connected to communicate with an external device, for example, through Bluetooth technology. The external device may be, for example, a mobile phone, a tablet, a smart watch, a laptop computer, etc. The secondary earphone may communicate with the main earphone, and the data sent by the external device may be sent to the main earphone, and at the same time sent to the secondary earphone via the main earphone, so that the main and secondary earphones can receive the data as synchronously as possible.

[0033] For further details about the embodiment of the charging box 10 of the present application, please refer to the detailed description below.

[0034] In conjunction with Figures 1 to 4, an embodiment of the present application provides a charging case 10 for earphones. The charging case 10 for earphones includes a cover 12 and a body 11. The body 11 is used to accommodate earphones. A receiving slot 1121 for accommodating the earphones is defined on the body 11. The shape of the receiving slot 1121 is configured to mimic the shape of the earphones, so that the receiving slot 1121 can accommodate the earphones on the one hand, and on the other hand, when the earphones are placed in the receiving slot 1121, the movement of the earphones is restricted, thereby providing a positioning function.

[0035] The box cover 12 is rotatably connected to the box body 11 and can rotate relative to the box body 11 between a closed position and an open position, so as to cover the earphones in the closed position and expose the earphones in the open position. The provision of the box cover 12 can cover the earphones when placed in the box body 11, thereby protecting the earphones, reducing the possibility of the earphones falling out of the box body 11, and protecting the earphones from dust and other contaminants.

[0036] In some embodiments, the charging box 10 includes a second elastic member (not shown), which connects the box body 11 and the box cover 12 and is used to drive the box cover 12 to rotate to the closed position when the box cover 12 rotates from the open position to the closed position. The second elastic member is, for example, a torsion spring or a spring, etc., which is not specifically limited here. When the box cover 12 is close to the box body 11, the second elastic member can apply a torque to the box cover 12 to force it to close, thereby enabling the box cover 12 to automatically close when it is close to the box body 11. Furthermore, when the box cover 12 is in the closed position, the torque applied by the second elastic member can also limit the opening of the box cover 12, thereby reducing the unexpected opening of the box cover 12 due to movement or vibration, and reducing the situation where the earphones fall off accidentally.

[0037] In some embodiments, further, the second elastic member is configured so that the lid 12 has a second transition position relative to the box body 11 between the open position and the closed position. When the lid 12 rotates from the second transition position to the open position, the elastic drive drives the lid 12 to rotate to the open position. When the lid 12 rotates from the second transition position to the closed position, the elastic drive supports 115 rotate to the closed position. Taking the box body 11 as an example where the box body 11 is fixed and the lid 12 rotates, the lid 12 rotates relative to the box body 11 around the second rotation axis 120, thereby achieving the opening or closing of the lid 12 relative to the box body 11. The elastic force applied by the second elastic member to the lid 12 during the process of opening or closing the lid 12 can change the position of the vector of the elastic force relative to the second rotation axis 120, thereby causing the direction of the torque applied by the second elastic member to the lid 12 to change, thereby causing the rotation tendency of the lid 12 to change during the process of opening or closing, thereby achieving the change in the above-mentioned elastic drive direction.

[0038] Specifically, with reference to Figures 2 to 3, let's take the case where the second elastic member is located below the second rotation axis 120, the rotation axis of the box cover 12 and the box body 11 is located on the right side of the charging box 10, and the box cover 12 can be opened by rotating clockwise and closed by rotating counterclockwise as an example. In the process of the box cover 12 changing from the closed position to the open position, first, with reference to Figure 2, the box cover 12 is in the closed position. At this time, the elastic force vector generated by the second elastic member on the box cover 12 is located to the right of the second rotation axis 120 (refer to the relative position relationship between F1 and the second rotation axis 120 in Figure 2). The box cover 12 will be subjected to a counterclockwise torque. The elastic force of the second elastic member will hinder the opening of the box cover 12. In this case, the user can manually apply a clockwise torque to overcome the torque generated by the second elastic member, thereby driving the box cover 12 to gradually open. As the lid 12 gradually opens, the position of the elastic force vector generated by the second elastic member changes relative to the second rotation axis 120. When the lid 12 is opened to the second transition position, the elastic force vector generated by the second elastic member points toward the center of the rotation axis (not shown), meaning that the second elastic member does not apply any 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 of the second rotation axis 120 (see the relative positional relationship between F2 and the second rotation axis 120 in FIG3 ), causing the lid 12 to be subjected to a clockwise torque. In this case, even if the user no longer applies clockwise torque, the second elastic member can still apply clockwise torque to the lid 12, thereby promoting rotation of the lid 12 toward 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 automatically open.

[0039] 2 and 3 , during the transition of the lid 12 from the open position to the closed position, first, with reference to FIG3 , the lid 12 is in the open position. At this time, the elastic force vector generated by the second elastic member on the lid 12 is located to the left of the second rotation axis 120 (refer to the relative positional relationship between F2 and the second rotation axis 120 in FIG3 ), and the lid 12 is subjected to a clockwise torque. The elastic force of the second elastic member will hinder the closing of the lid 12. In this 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. During the gradual closing of the lid 12, the position of the elastic force vector generated by the second elastic member changes relative to the second rotation axis 120. 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 rotation axis (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 rotation axis 120 (see the relative positional relationship between F1 and the second rotation axis 120 in FIG2 ). This causes a counterclockwise torque to act on the lid 12. In this case, even if the user no longer applies the counterclockwise torque, the second elastic member can still exert a counterclockwise torque on the lid 12, thereby promoting the rotation of the lid 12 toward the closed position. In other words, after the lid 12 passes the second transition position, the torque exerted by the second elastic member can cause the lid 12 to automatically close. Furthermore, after the lid 12 is closed, the torque exerted by the second elastic member can also hinder the opening of the lid 12, thereby preventing the lid 12 from opening unexpectedly.

[0040] In some embodiments, the charging case 10 further includes a support member 115 rotatably mounted on the case body 11 and rotatable relative to the case body 11 between a storage position and a support position, such that the support member 115 at least partially protrudes from the case body 11 in the support position and is retracted within the case body 11 in the storage position. The case 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 case lid 12 are configured to form a support area for placing a mobile terminal in the support position and the open position, respectively. When the mobile terminal is placed in the support area, the protruding portion of the case lid 12 and the support member 115 jointly support the mobile terminal. By providing the support member 115, the charging case 10 not only serves as a tool for accommodating earphones, but also functions as a mobile terminal support member 115, making it easier for users to use. Specifically, the support member 115 forms a first fulcrum when in the support position, and a second fulcrum when the case lid 12 is in the open position. The first and second fulcrums jointly support the mobile terminal.

[0041] In some embodiments, in conjunction with Figures 5 and 6, the number of support positions is at least two, and the support member 115 can be rotated through at least two support positions in sequence from the storage position, and the rotation angles corresponding to rotation from the storage position to different support positions are different. The support member 115 can be maintained in different support positions by a stopper such as a buckle, damping, or magnetic attraction, thereby forming a first fulcrum with different positions in different support positions. Furthermore, the number of open positions is at least two, and the box cover 12 can be rotated through at least two open positions in sequence from the closed position, and the rotation angles corresponding to rotation from the closed position to different open positions are different. The box cover 12 can also be maintained in different open positions by a stopper such as a buckle, damping, or magnetic attraction, thereby forming a second fulcrum with different positions in different open positions. In this way, the support member 115 and the box cover 12 can form a first fulcrum and a second fulcrum with different positions, and the different first fulcrums and second fulcrums can support the mobile terminal at different angles, thereby adapting to the diverse support needs of users.

[0042] In some embodiments, referring to Figures 1 to 3 , the case body 11 has a top 112 (or the inner lining of the case body 11 ). The top 112 is provided with a receiving slot 1121 for accommodating headphones. The receiving slot 1121 is located between the support member 115 and the rotation axis of the lid 12 so as to receive the headphones through the top 112. The lid 12 can cover the top 112 and the support member 115 in the closed position, and expose the top 112 in the open position. The support member 115 is rotatably connected to the top 112. The support member 115 is positioned at a certain distance from the receiving slot 1121 to reduce the mutual influence between the support member 115 and the headphones.

[0043] In some embodiments, the top portion 112 defines a mounting slot 1122, and the support member 115 is rotatably disposed within the mounting slot 1122. In the supporting position, the support member 115 is at least partially located outside the mounting slot 1122, thereby forming a support area for the mobile terminal in conjunction with the case cover 12. In the stowed position, the support member 115 is housed within the mounting slot 1122, thereby preventing interference between the support member 115 and the case cover 12 or the earphones.

[0044] In some embodiments, in combination with Figures 2 and 3, the support member 115 has a free end away from its rotation axis, and when the support member 115 is in the storage position, there is a hand-clasping space between the free end and the side wall of the accommodating groove 1121. The hand-clasping space is used for the user to rotate the support member 115 to drive the support member 115 to rotate from the storage position to the supporting position.

[0045] In some embodiments, the support member 115 is configured to restrict its own rotation in the 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, vibration and movement of the case body 11 can easily cause the support member 115 to rotate, or even rotate to the storage position, rendering it unable to effectively support the mobile terminal. Therefore, configuring the support member 115 to restrict its own rotation in the direction from the storage position to the support position when in the support position can ensure that the support member 115 is stably located in the support position, thereby improving the stability of supporting the mobile terminal.

[0046] Specifically, when the support member 115 is in the supporting position, the box body 11 abuts against the support member 115 in the rotation direction from the supporting position to the storage position to limit the support member 115 from rotating in the supporting position along the rotation direction from the supporting position to the storage position. For example, the box body 11 can be provided with a limiting structure (limiting protrusions, limiting springs, etc.), and the support member 115 can pass through the limiting structure to the supporting position through a large torque during the rotation process of the user. When in the supporting position, the limiting structure can abut against the support member 115, thereby limiting the rotation of the support member 115, so that the support member 115 can stably support the mobile terminal. During the process of the support member 115 rotating to the storage position, the user can also apply force to the support member 115 to overcome the limiting force of the limiting structure and rotate it to the storage position.

[0047] In some embodiments, further in conjunction with FIG4 , the charging box 10 includes a first magnetic member 1151 and a second magnetic member 123, wherein the first magnetic member 1151 is provided on the support member 115, and the second magnetic member 123 is provided on the box cover 12. 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 supporting position and the box cover 12 is in the process of changing from the open position to the closed position. When the box cover 12 is used to rotate from the open position to the closed position, the magnetic repulsion between the second magnetic member 123 and the first magnetic member 1151 drives the support member 115 to rotate from the supporting position to the storage position. With such a configuration, during the closing process of the charging box 10, the cooperation between the first magnetic member 1151 and the second magnetic member 123 can automatically rotate the support member 115 in the supporting position to the storage position without the need for active operation by the user, thereby improving the convenience of using the support member 115. The first magnetic member 1151 and the second magnetic member 123 can be arranged relative to each other when the support member 115 is in the supporting position during the closing process of the box lid 12, and the relative magnetic poles are the same. The first magnetic member 1151 and the second magnetic member 123 can also be arranged not relative to each other, but the direction of the magnetic field generated by the first magnetic member 1151 at the second magnetic member 123 is opposite to the direction of the magnetic flux lines of the second magnetic member 123, thereby generating a repulsive force. The magnetic member refers to an element that can generate a magnetic field, such as a magnet. The magnetic element can have a magnetic field, and the magnetic members can generate magnetic forces between each other. In some embodiments, the magnet can include a metal alloy magnet, ferrite, etc. The metal alloy magnet can include neodymium iron boron, samarium cobalt, aluminum nickel cobalt, iron chromium cobalt, aluminum iron boron, iron carbon aluminum, or the like, or a combination thereof. The ferrite can include barium ferrite, steel ferrite, manganese ferrite, lithium manganese ferrite, or the like, or a combination thereof.

[0048] In some embodiments, the support member 115 is configured to limit its own rotation in the direction of rotation from the storage position to the support position when in the support position. Specifically, the charging box 10 includes a first magnetic member 113, which is provided on the box body 11 and is spaced apart from the support member 115; the first magnetic member 1151 and the first magnetic 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 remains in the support position. Among them, the first magnetic member 113 can be a magnetic member such as a magnet, or it can be a soft magnetic material. The soft magnetic material can include metal materials, metal alloys, metal oxide materials, amorphous metal materials, etc., such as iron, iron-silicon alloys, iron-aluminum alloys, nickel-iron alloys, iron-cobalt alloys, low carbon steel, silicon steel sheets, silicon steel sheets, ferrites, etc. When the first magnetic member 113 is a magnetic member, when the support member 115 is in the support position, the magnetic poles of the first magnetic member 113 can be arranged opposite to the first magnetic member 1151. The first magnetic member 1151 and the first magnetic member 113 may not be arranged opposite to each other, but the magnetic field generated by the first magnetic member 113 is opposite to the direction of the magnetic flux lines of the first magnetic member 1151 at the first magnetic member 1151, thereby generating a repulsive force.

[0049] In one embodiment, the second magnetic member 123 and the first magnetic member 113 are configured to magnetically attract each other when the lid 12 is in the closed position, thereby maintaining the lid 12 in the closed position. The first magnetic member 113 can be made of a soft magnetic material, thereby generating an attractive force with the second magnetic member 123. The first magnetic member 113 can also be made of a magnetic material such as a magnet. When the lid 12 is in the closed position, the first magnetic member 113 and the second magnetic member 123 are disposed opposite each other, with opposite magnetic poles, thereby generating an attractive force.

[0050] In some embodiments, the magnetic assembly further includes a second magnetic member 114, which is disposed on the box body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetic member 114 are configured to magnetically attract each other when the support member 115 is in the storage position, thereby maintaining the support member 115 in the storage position. The provision of the second magnetic member 114 enables the support member 115 to be stably maintained in the storage position, reduces unexpected rotation of the support member 115 by the user, and reduces collisions between the support member 115 and the box body 11, the box cover 12, etc.

[0051] Specifically, when the support member 115 is in the supporting position, the magnetic attraction between the first magnetic member 1151 and the first magnetic member 113 is greater than the magnetic attraction between the first magnetic member 1151 and the second magnetic member 114. When the support member 115 is in the storage position, the magnetic attraction between the first magnetic member 1151 and the second magnetic member 114 is greater than the magnetic attraction between the first magnetic member 1151 and the first magnetic member 113.

[0052] In summary, the first magnetic part 1151 and the second magnetic part 123 need to generate repulsive force, so both can be magnets, and the first magnetic part 113 and the second magnetic part 114 both generate attractive force with the first magnetic part 1151 and the second magnetic part 123, so the first magnetic part 113 and the second magnetic part 114 can be magnets or soft magnetic materials.

[0053] In some embodiments, the first magnetic member 1151 is embedded in the support member 115, or is integrally provided with the support member 115 as a core when the support member 115 is manufactured. In some embodiments, the second magnetic member 123 is embedded in the box cover 12 so as not to be visible on the outer surface of the box cover 12. For example, the box cover 12 may include an outer cover 121 and an inner cover 122 (or referred to as a box cover 12 lining), and the outer cover 121 and / or the inner cover 122 are rotatably connected to the box body 11. The inner cover 122 is arranged on the inner side of the outer cover 121, and when the box cover 12 is in a closed state, the inner cover 122 is located between the outer cover 121 and the box body 11, and the second magnetic member 123 is arranged between the outer cover 121 and the inner cover 122. In some embodiments, the first magnetic member 113 is embedded in the box body 11 so as not to be visible on the outer surface of the box body 11. For example, the box body 11 includes a shell and a top 112 (or referred to as the inner lining of the box body 11 ), the top 112 is provided with a receiving groove 1121 for receiving the earphone, and the first magnetic member 113 is arranged between the shell and the top 112 .

[0054] In some embodiments, with reference to FIG3 , the support member 115 can be rotatably connected to the housing 11 about a first rotation axis 1150 and has a free end that is spaced apart from the first rotation axis 1150 and rotates about the first rotation axis 1150. The free end of the support member 115 approaches or moves away from the second rotation axis 120 during rotation about the first rotation axis 1150. In the supported state, the free end is further away from the second rotation axis 120 than in the stored state, and in the supported state, protrudes from the housing 11 to support the mobile terminal. In other words, the opening direction of the support member 115 is opposite to the opening direction of the lid 12. For example, if the lid 12 rotates clockwise to open, the support member 115 rotates counterclockwise to open. With this arrangement, when the lid 12 is in the open position and the support member 115 is in the supporting position, the pressure exerted by the mobile terminal between the two tends to maintain the lid 12 in the open position and the support member 115 in the supporting position.

[0055] In some embodiments, in conjunction with FIG3 , the support member 115 can rotate relative to the box body 11 about a first rotation axis 1150, and the first magnetic member 113 and the second magnetic member 114 are respectively located on either side of the first rotation axis 1150. The box body 11 is provided with a first limiting portion 116 and a second limiting portion 117, which are respectively located on either side of the first rotation axis 1150 and correspond to the first magnetic member 113 and the second magnetic member 114. The first limiting portion 116 is used to abut the support member when the support member 115 rotates from the storage position to the supporting position, thereby cooperating with the first magnetic member 113 to maintain the support member 115 in the supporting position. The second limiting portion 117 abuts the support member 115 when the support member rotates from the supporting position to the storage position, thereby cooperating with the second magnetic member 114 to maintain the support member in the storage position. During the process of the support member 115 rotating by cooperating with the first magnetic member 113 and the second magnetic member 114 through the first magnetic member 1151, the support member 115 will be continuously subjected to the action of torque. When the support member 115 rotates to the supporting position or the storage position, it is necessary to balance the torque exerted on the support member 115 to limit the further rotation of the support member 115. By setting the first limit portion 116 and the second limit portion 117, the support member 115 can be prevented from further rotating during the supporting and storage processes.

[0056] Furthermore, the box body 11 defines a mounting slot 1122, within which the support member 115 is rotatably disposed. The support member 115 is at least partially located outside the mounting slot 1122 when in the supporting position and is accommodated within the mounting slot 1122 when in the storage position. A portion of the sidewalls of the mounting slot 1122 form a first limiting portion 116, and the bottom wall of the mounting slot forms a second limiting portion 117. When the support member 115 rotates to the supporting position, the support member 115 directly abuts against a portion of the sidewalls of the mounting slot 1122, thereby limiting further rotation of the support member 115. Therefore, a portion of the sidewalls of the mounting slot 1122 form the first limiting portion 116. When the support member 115 rotates to the storage position, the support member 115 abuts against the bottom wall of the mounting slot 1122, thereby limiting further rotation of the support member 115. Therefore, the bottom wall of the mounting slot 1122 forms the second limiting portion 117.

[0057] In some embodiments, the charging box 10 includes a first elastic member (not shown), which connects the box body 11 and the support member 115. The first elastic member is configured so that the support member 115 has a first transition position relative to the box body 11 between the supporting position and the storage position. When the support member 115 rotates from the first transition position to the supporting position, the elastic member 115 is driven to rotate to the supporting position. When the support member 115 rotates from the first transition position to the storage position, the elastic member 115 is driven to rotate to the storage position. Taking the case where the box body 11 is fixed and the support member 115 rotates as an example, the support member 115 rotates relative to the box body 11 along the first rotation axis 1150, thereby achieving support or storage of the support member 115 relative to the box body 11. The elastic force applied by the first elastic member to the support member 115 may change in position relative to the first rotating axis 1150 during the process of opening or closing the support member 115, thereby causing the direction of the torque applied by the first elastic member to the support member 115 to change, thereby causing the rotation tendency of the support member 115 to change during the process of opening or closing the support member 115, thereby achieving the above-mentioned change in the elastic driving direction.

[0058] Specifically, take the example of a first elastic member located below the first rotation axis 1150 and at the left end of the support member 115 when in the storage position. The support member 115 can be stored by rotating clockwise and supported by rotating counterclockwise. During the transition of the support member 115 from the storage position to the support position, first, the support member 115 is in the storage position. At this time, the elastic force vector generated by the first elastic member on the support member 115 is located to the left of the first rotation axis 1150. The torque applied to the support member 115 causes the support member 115 to tend to rotate clockwise. The elastic force of the first elastic member will hinder the opening of the support member 115. In this case, the user can 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. As the support member 115 gradually opens, the position of the elastic force vector generated by the first elastic member changes relative to the first rotation axis 1150. When the support member 115 opens to the first transition position, the elastic force vector generated by the first elastic member points toward the center of the rotation axis, meaning that the first elastic member does not apply a rotational 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 of the first rotation axis 1150, causing the support member 115 to be subjected to a counterclockwise torque. In this case, even if the user no longer applies counterclockwise torque, the first elastic member can still apply a counterclockwise torque to the support member 115, thereby promoting the rotation of the support member 115 toward the supporting position. In other words, after the support member 115 passes the first transition position, the torque applied by the first elastic member can automatically cause the support member 115 to rotate toward the supporting position.

[0059] During the transition of the support member 115 from the supporting position to the stowed position, the support member 115 is initially in the supporting position. At this point, the elastic force vector generated by the first elastic member on the support member 115 is located to the right of the first rotation axis 1150, and the support member 115 is subjected to a counterclockwise torque. The elastic force of the first elastic member will hinder the stowage of the support member 115. In this case, the user can manually apply a clockwise torque to overcome the torque generated by the first elastic member, thereby driving the support member 115 to gradually stow. During the stowage process of the support member 115, the position of the elastic force vector generated by the first elastic member changes relative to the first rotation axis 1150. When the support member 115 is stowed in the first transition position, the elastic force vector generated by the first elastic member points to the center of the rotation axis, meaning that the first elastic member does not apply a torque to the support member 115. As the support member 115 cover continues to be retracted, the elastic force vector generated by the first elastic member shifts to the left side of the first rotation axis 1150, and the support member 115 is subjected to a clockwise torque. In this case, even if the user no longer applies the clockwise torque, the first elastic member can still apply the clockwise torque to the support member 115, thereby promoting the rotation of the support member 115 to the retracted position. In other words, after the support member 115 passes the first transition position, the torque applied by the first elastic member can cause the support member 115 to automatically retract.

[0060] In some embodiments, in conjunction with Figure 4, the charging box 10 includes a first magnetic member 1151 and a second magnetic member 123, the first magnetic member 1151 is provided on the support member 115, and the second magnetic member 123 is provided on the box cover 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 exert a repulsive force on the first magnetic member 1151 on the side of the support position away from the storage position of the support member 115, so as to 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 supporting position and the box cover 12 is in the closed position. When the box cover 12 is used to rotate from the open position to the closed position, the magnetic repulsion between the second magnetic member 123 and the first magnetic member 1151 drives the support member 115 to rotate from the supporting position to the storage position. With such an arrangement, during the closing process of the charging box 10, the cooperation between the first magnetic member 1151 and the second magnetic member 123 can automatically rotate the support member 115 located in the supporting position to the storage position, without the need for active operation by the user, thereby improving the convenience of using the support member 115. The first magnetic member 1151 and the second magnetic member 123 can be arranged relative to each other when the support member 115 is in the supporting position during the closing process of the box cover 12, and the relative magnetic poles are the same. The first magnetic member 1151 and the second magnetic member 123 may also not be arranged relative to each other, but the direction of the magnetic field generated by the first magnetic member 1151 at the second magnetic member 123 is opposite to the direction of the magnetic flux lines of the second magnetic member 123, thereby generating a repulsive force.

[0061] In some embodiments, the support member 115 is configured to limit its own rotation in the direction of rotation from the storage position to the support position when in the supporting position. Specifically, the charging box 10 includes a first magnetic member 113, which is arranged on the box body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the first magnetic member 113 are configured to magnetically attract each other when the support member 115 is in the supporting position, so that the support member 115 remains in the supporting position. The first magnetic member 1151 is closer to the second rotating shaft 120 than the first magnetic member 113, so that the first magnetic member 113 can generate an attractive 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 stabilizing the support member 115 in the supporting position.

[0062] In some embodiments, the box cover 12 is covered on the box body 11 along a preset direction when the box cover 12 is in the closed position; when the box cover 12 is in the closed position, the second magnetic member 123 and the first magnetic member 113 are spaced apart along a preset direction and magnetically attracted to each other to keep the box cover 12 in the closed position, wherein the preset direction can be the thickness direction of the charging box 10.

[0063] On the basis of the above embodiment, the charging box 10 includes a second magnetic member 114, which is provided on the box body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetic 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 remains in the storage position. By providing the second magnetic member 114, the support member 115 can be stably in the storage position, reducing the rotation of the support member 115 that is not expected by the user, and reducing the collision of the support member 115 with the box body 11, the box cover 12, etc.

[0064] The second embodiment is shown in FIG. 7 to FIG. 17 .

[0065] An embodiment of the present application provides an earphone system. The earphone system includes a charging box 10 and earphones. The charging box 10 is used to accommodate the earphones and to charge the earphones after the earphones are placed in the charging box 10. Optionally, the charging box 10 may include a box cover 11 and a box body 12 that are connected to each other. The box body 12 is provided with two receiving slots 122. The number of receiving slots 122 and the number of earphones may be the same. The receiving slots 122 are used to accommodate earphones. The box cover 11 is rotatably / slidably connected to the box body 12 for selectively covering the receiving slots 122. For example, the box cover 11 is rotatably connected to the box body 12 by a rotating shaft to realize a flip-top design. For example, the box cover 11 can slide relative to the box body 12 by the cooperation of a slide rail and a slider, thereby realizing a sliding design.

[0066] The charging case 10 can charge the earphones. When the earphones are placed in the receiving slot 122, they can be electrically connected to the earphones, thereby charging the earphones. For example, the receiving slot 122 may be provided with charging contacts (shown in Figure 7 but not labeled), and the earphones may also be provided with corresponding charging contacts (not shown). When the earphones are placed in the receiving slot 122, the charging contacts of the earphones and the charging contacts of the charging case 10 can come into contact, achieving an electrical connection. Of course, the charging case 10 can also be used to charge the earphones wirelessly. The charging case 10 can be structurally and / or electrically connected to the earphones through magnetic attraction. When the earphones are placed in the receiving slot 122, the charging case 10 and the earphones are magnetically attached. The two earphones can be divided into a primary earphone and a secondary earphone. The primary earphone can communicate with external devices, for example, via Bluetooth technology. The external device can be a mobile phone, tablet, smartwatch, laptop, etc. The secondary earphone can communicate with the primary earphone. Data sent by the external device can be sent to the primary earphone and simultaneously transmitted to the secondary earphone via the primary earphone, so that the primary and secondary earphones can receive data as synchronously as possible.

[0067] For further details about the embodiment of the charging box 10 of the present application, please refer to the detailed description below.

[0068] In conjunction with Figure 7, an embodiment of the present application provides a charging box 10 for earphones. The charging box 10 includes a box body 12, a box cover 11, and a support assembly 124. The box body 12 is used to accommodate earphones, and a receiving groove 122 for accommodating earphones is provided on the box body 12. The shape of the receiving groove 122 is configured to imitate the shape of the earphones, so that the receiving groove 122 can accommodate the earphones on the one hand, and on the other hand, when the earphones are placed in the receiving groove 122, it can limit the movement of the earphones and play a positioning role. The box body 12 can also be provided with a battery, a power control board, etc. for managing the input and output of the power supply to charge the earphones.

[0069] The box cover 11 is rotatably connected to the box body 12 and can rotate relative to the box body 12 between a closed position and an open position, so that the earphones are covered in the closed position and exposed in the open position. The arrangement of the box cover 11 can cover the earphones when placed in the box body 12, thereby protecting the earphones, reducing the possibility of the earphones falling out of the box body 12, and protecting the earphones from dust and other contaminants.

[0070] 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 disposed on the housing 12 and is rotatable relative to the housing 12 between a storage position and a support position, so that when in the support position, it at least partially protrudes from the housing 12. When the support member 1241 is in the support position and the lid 11 is in the open position, the protruding portion of the support member 1241 and the lid 11 are spaced apart from each other and jointly support the mobile terminal. When in the storage position, the support member 1241 is retracted within the housing 12, thereby preventing interference between the support member 1241 and the lid 11 or the earphones, and reducing the space occupied by the support member 1241. The first elastic member 125 connects the support member 1241 and the housing 12, and is used 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 to keep the support member 1241 in the storage position or the supporting position, and can also provide a force to automatically rotate the support member 1241 to the storage position or the supporting position. The support member 1241 forms a first fulcrum when it is in the supporting position, and the box cover 11 forms a second fulcrum when it is in the open position, and the first fulcrum and the second fulcrum are used together to support the mobile terminal. Optionally, the support member 1241 can be engaged with the box body 12 during the rotation process and have an intermediate supporting position, and the support member 1241 can also form a first fulcrum with a different position when it is in the intermediate position. The box cover 11 can also be engaged with the box body 12 during the opening process to form an intermediate open position, and the box cover forms a second fulcrum with a different position when it is in the intermediate open position. In the aforementioned manner, the positions of the first fulcrum and the second fulcrum can be changed to support the mobile terminal at different angles.

[0071] In some embodiments, referring to FIG8 , the case body 12 defines a mounting slot 123. The case cover 11 covers the mounting slot 123 when in the closed position, and exposes the mounting slot 123 when in the open position. A support member 1241 is rotatably disposed within the mounting slot 123. In the supporting position, the support member 1241 at least partially protrudes from the mounting slot 123, thereby cooperating with the case cover 11 to support the mobile terminal. In the stowed position, the support member 1241 is located within the mounting slot 123, thereby concealing the support member 1241 and reducing its protrusion from the surface of the case body 12.

[0072] Specifically, the box body 12 includes an outer shell and a top wall (shown in FIG8 but not marked). The top wall is provided with the aforementioned mounting groove 123, and the support member 1241 is rotatably arranged in the mounting groove 123. The support member 1241 is at least partially located outside the mounting groove 123 when in the supporting position, and is accommodated in the mounting groove 123 when in the storage position. Optionally, the support member 1241 has a support portion 1243 away from its rotation axis, and when the support member 1241 is in the storage position, there is a hand-clasp space (shown in FIG9 but not marked) between its support portion 1243 and the side wall of the mounting groove 123. The hand-clasp space is used for the user to rotate the support member 1241 to drive the support member 1241 to rotate from the storage position to the supporting position.

[0073] The charging box 10 also includes a second elastic member 126, which connects the box body 12 and the box cover 11. The second elastic member 126 is configured so that the box cover 11 has a second transition position between the open position and the closed position relative to the box body 12. When the box cover 11 rotates from the second transition position to the open position, the elastic member drives the box cover 11 to rotate to the open position. When the box cover 11 rotates from the second transition position to the closed position, the elastic member drives the box cover 11 to rotate to the closed position.

[0074] Taking the case where the box body 12 is fixed and the box lid 11 rotates as an example, the box lid 11 rotates relative to the box body 12 along the first rotation axis 111, thereby achieving opening or closing of the box lid 11 relative to the box body 12. During the process of opening or closing the box lid 11, the elastic force applied by the second elastic member 126 on the box lid 11 can change in position relative to the first rotation axis 111, thereby causing the direction of the torque applied by the second elastic member 126 on the box lid 11 to change. This, in turn, causes the rotational tendency of the box lid 11 to change during the opening or closing process, thereby achieving the aforementioned change in the elastic drive direction.

[0075] Specifically, in conjunction with Figures 9 and 10, take the case where the second elastic member 126 is located below the first rotation axis 111, the rotation axis of the box cover 11 and the box body 12 is located on the right side of the charging box 10, and the box cover 11 can be opened by rotating clockwise and closed by rotating counterclockwise as an example. In the process of the box cover 11 changing from the closed position to the open position, first, the box cover 11 is in the closed position. At this time, the elastic force vector generated by the second elastic member 126 on the box cover 11 is located to the right of the first rotation axis 111 (indicated by F1 in Figure 9), and the box cover 11 will be subjected to a counterclockwise torque. The elastic force of the second elastic member 126 will hinder the opening of the box cover 11. In this case, the user can manually apply a clockwise torque to overcome the torque generated by the second elastic member 126, thereby driving the box cover 11 to gradually open. As the lid 11 gradually opens, the position of the elastic force vector generated by the second elastic member 126 relative to the first rotation axis 111 changes. When the lid 11 is opened to the second transition position, the elastic force vector generated by the second elastic member 126 points toward the center of the rotation axis (not shown), meaning that the second elastic member 126 does not apply any 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 of the first rotation axis 111 (see F2 in FIG. 10 ), causing the lid 11 to be subjected to a clockwise torque. In this case, even if the user no longer applies clockwise torque, the second elastic member 126 can still apply clockwise torque to the lid 11, thereby promoting rotation of the lid 11 toward 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 automatically cause the lid 11 to open.

[0076] During the transition of the lid 11 from the open position to the closed position, first, with reference to FIG9 , the lid 11 is in the open position. At this time, the elastic force vector generated by the second elastic member 126 on the lid 11 is located to the left of the first rotation axis 111 (refer to the relative positional relationship between F2 and the first rotation axis 111 in FIG9 ), and the lid 11 is subjected to a clockwise torque. The elastic force of the second elastic member 126 will hinder the closing of the lid 11. In this case, the user can manually apply a counterclockwise torque to overcome the torque generated by the second elastic member 126, thereby driving the lid 11 to gradually close. During the gradual closing of the lid 11, the position of the elastic force vector generated by the second elastic member 126 relative to the first rotation axis 111 changes. When the lid 11 is closed 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 close, the elastic force vector generated by the second elastic member 126 shifts to the right of the first rotation axis 111 (refer to the relative positional relationship between F1 and the first rotation axis 111 in FIG8 ). The lid 11 is then subjected to a counterclockwise torque. In this case, even if the user no longer applies the counterclockwise torque, the second elastic member 126 can still apply the counterclockwise torque to the lid 11, thereby promoting the rotation of the lid 11 toward 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 cause the lid 11 to automatically close. Furthermore, 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 the lid 11 from opening unexpectedly.

[0077] In some embodiments, the first elastic member 125 is configured to elastically constrain the support member 1241 in the stowed position when the support member 1241 is in the stowed position, and to elastically constrain the support member 1241 in the supporting position when the support member 1241 is in the supporting position. Specifically, because the support member 1241 is rotatably connected to the housing 12 and has a rotation axis, the first elastic member 125 can be configured to change position as the support member 1241 rotates, thereby changing the vector direction of the elastic force. For example, when the housing 12 is in the stowed position, the positional relationship between the vector direction of the first elastic member 125 and the rotation axis can be set to apply a torque to the support member 1241 that prevents it from opening from the stowed position. When the user applies an external force to open the support member 1241, the position of the first elastic member 125 will also change relative to the support member 1241. When the support member 1241 is in the supporting position, the positional relationship between the vector direction of the first elastic member 125 and the rotation axis can be set to apply a torque to the support member 1241 that prevents it from retracting from the supporting position.

[0078] In some embodiments, with reference to Figures 11 to 13, the first elastic member 125 is configured such that the support member 1241 has a first transition position (with reference to Figure 12) relative to the box body 12, which is located between the support position (with reference to Figure 13) and the storage position (with reference to Figure 5). When the support member 1241 rotates 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 constrains the support member 1241 in the support position. When the support member 1241 rotates 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 constrains 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 to the support member 1241 by the first elastic member 125 changes.

[0079] Taking the case where the box body 12 is fixed and the support member 1241 rotates as an example, the support member 1241 rotates relative to the box body 12 along the second rotation axis 127 (or the preset rotation axis), thereby achieving support or storage of the support member 1241 relative to the box body 12. The elastic force exerted by the first elastic member 125 on the support member 1241 can change the position of the elastic force vector relative to the second rotation axis 127 during the process of opening or closing the support member 1241, thereby causing the direction of the torque exerted by the first elastic member 125 on the support member 1241 to change. This, in turn, causes the rotational tendency of the support member 1241 to change during the process of opening or closing the support member 1241, thereby achieving the aforementioned change in the elastic drive direction.

[0080] In some embodiments, the support member 1241 includes a rotating portion corresponding to a preset rotation axis, and supporting portions 1243 and connecting portions 1244 disposed at both ends of the rotating portion and rotating about the preset rotation axis. The supporting portions 1243 and connecting portions 1244 are located on either side of the preset rotation axis. When the support member 1241 is in the supporting state, the supporting portion 1243 protrudes from the box body 12 to cooperate with the box cover 11 to support the mobile terminal. The connecting portion 1244 can be connected to the first elastic member 125 to drive the support member 1241 to rotate.

[0081] In some embodiments, the support member 1241 is rotatably disposed on the box body 12 around a preset second rotation axis 127, and the 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. The second end of the first elastic member 125 is connected to the box body 12. Optionally, the direction of the elastic force generated by the first elastic member 125 is parallel to the direction of the 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, the line connecting the connecting portion 1244 and the second end of the first elastic member 125 intersects 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 this time, the elastic force of the first elastic member 125 cannot apply a rotational torque to the support member 1241. At this time, the support member 1241 is in the first transition position. When the support member 1241 is in the storage position and the supporting position, the line between the connecting portion 1244 and the second end of the first elastic member 125 is skewed from the rotation axis. In this way, the elastic force of the first elastic member 125 can be spatially spaced from the preset rotation axis, so that the elastic force of the first elastic member 125 can become a torque that drives the support member 1241 to rotate or drives the support member 1241 to remain in the supporting position or the storage position.

[0082] In some embodiments, with reference to FIG11 , when the support member 1241 is in the stowed position, the predetermined 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 have a tendency to rotate in a first direction. When the support member 1241 is in the supporting position, with reference to FIG13 , 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 and the second direction are opposite, with the first direction being the direction of rotation from the supporting position toward the stowed direction. The second direction is the direction of rotation from the stowed position toward the supporting position.

[0083] In some embodiments, referring to Figures 11 to 13 , when the support member 1241 is positioned between the stowed position and the first transition position, the predetermined 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 have a tendency to rotate in the first direction (see F in Figure 11 ). When the support member 1241 is positioned 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 (see F in Figure 13 ).

[0084] In some embodiments, the elastic deformation of the first elastic member 125 when the support member 1241 is in the first transition position is greater than the elastic deformation of the support member 1241 when it is in the supporting position or the storage position. When the support member 1241 rotates from the first transition position to the supporting position or the storage position, the first elastic member 125 elastically drives the support member 1241 to rotate to the supporting position or the storage position accordingly through elastic recovery. In other words, if the first elastic member 125 is in a compressed state, the compression of the first elastic member 125 is at its maximum when the support member 1241 is in the first transition position. With this configuration, after the support member 1241 passes through the first transition position, the elastic force of the first elastic member 125 is greater, allowing the support member 1241 to rotate to the storage position or the supporting position more quickly.

[0085] In some embodiments, the first elastic member 125 may be a spring. The above embodiments will be described below using the first elastic member 125 as an example. Specifically, the first elastic member 125 is positioned below the second rotation axis 127 and near the left end of the support member 1241 in the storage position. For example, the support member 1241 can rotate clockwise to the storage position, and counterclockwise to the support position. During the transition of the support member 1241 from the storage position to the support position, first, referring to FIG11 , the support member 1241 is in the storage position. At this point, the elastic force vector generated by the first elastic member 125 on the lid 11 is located to the left of the second rotation axis 127 (illustrated by F in FIG11 ). The torque applied to the support member 1241 causes the support member 1241 to rotate clockwise. The elastic force of the first elastic member 125 can hinder the opening of the support member 1241. In this case, the user can 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. As support member 1241 gradually opens, the position of the elastic force vector generated by first elastic member 125 relative to second rotation axis 127 changes. Referring to FIG12 , when support member 1241 opens to the first transition position, the elastic force vector generated by first elastic member 125 points toward the center of the rotation axis, meaning that first elastic member 125 does not exert a rotational torque on support member 1241. Referring to FIG13 , as support member 1241 continues to open, the elastic force vector generated by first elastic member 125 shifts to the right of second rotation axis 127 (as indicated by F in FIG13 ), causing support member 1241 to be subjected to a counterclockwise torque. In this case, even if the user no longer applies counterclockwise torque, first elastic member 125 can still exert a counterclockwise torque on support member 1241, thereby promoting rotation of support member 1241 toward the supporting position. In other words, after support member 1241 passes through the first transition position, the torque exerted by first elastic member 125 can automatically cause support member 1241 to rotate toward the supporting position.

[0086] During the transition of support member 1241 from the supporting position to the stowed position, first, as shown in FIG13 , support member 1241 is in the supporting position. At this point, the elastic force vector generated by first elastic member 125 on support member 1241 is located to the right of second rotation axis 127 (see F in FIG13 ), and support member 1241 is subjected to a counterclockwise torque. The elastic force of first elastic member 125 hinders the stowage of support member 1241. In this case, a user can manually apply a clockwise torque to overcome the torque generated by first elastic member 125, thereby driving support member 1241 to gradually stow. During the stowage process, the position of the elastic force vector generated by first elastic member 125 relative to second rotation axis 127 changes. When support member 1241 is stowed in the first transition position, as shown in FIG12 , the elastic force vector generated by first elastic member 125 points toward the center of the rotation axis, meaning that first elastic member 125 does not exert a torque on support member 1241. As the support member 1241 cover continues to be retracted, as shown in FIG11 , the elastic force vector generated by the first elastic member 125 changes to the left of the second rotation axis 127 (see F in FIG11 ), 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 still apply the clockwise torque to the support member 1241, thereby promoting the rotation of the support member 1241 to the retracted position. In other words, after the support member 1241 passes the first transition position, the torque applied by the first elastic member 125 can cause the support member 1241 to be automatically retracted.

[0087] In some embodiments, the support member 1241 is further provided with a limiting portion 1242, which can abut against the box body 12 when the support member 1241 is in the supporting position, thereby limiting further rotation of the support member 1241 and keeping the support member 1241 in the supporting position.

[0088] In conjunction with Figures 14 to 17 , in other embodiments, the first elastic member 125 may be a spring. The above embodiment will be described below using the spring as an example. The support member 1241 is provided with a limiting portion 1242, which is spaced apart from the predetermined rotation axis and rotates about the predetermined rotation axis. The first elastic member 125 is fixed to the box body 12 and includes a fixed section 1252 and an elastically movable section 1251 that is elastically movable relative to the box body 12. The elastically movable section 1251 includes a raised portion 12511 that arches toward the limiting portion 1242 and two connecting portions 12512 connected to either side of the raised portion 12511. The first elastic member 125 also includes a fixed section 1252, which is connected to one end of the two elastically movable sections 1251 and is fixedly connected to the box body 12.

[0089] When the support member 1241 rotates, the limiting portion 1242 can pass over the protrusion 12511 and move between the two connecting portions 12512. As the limiting portion 1242 passes over the protrusion 12511 from the connecting portion 12512, the elastic movable section 1251 elastically deforms. The elastic force generated by this elastic deformation can act on the support member 1241 through the limiting portion 1242, thereby applying a rotational torque to the support member 1241. The limiting portion 1242 elastically abuts the protrusion 12511 when the support member 1241 is in the first transition position, and elastically abuts the two connecting portions 12512 when the support member 1241 is in the storage position and the supporting position.

[0090] In some embodiments, there are two elastic movable segments 1251, and the two elastic movable segments 1251 are located at both ends of the support member 1241 and are arranged opposite to each other; there are two limiting portions 1242, and the two limiting portions 1242 are extended along the direction of the preset rotation axis. The two elastic movable segments 1251 are used to abut against the two limiting portions 1242 one by one. By setting the two elastic movable segments 1251 to abut against the limiting portions 1242, the force applied by the first elastic member 125 to the support member 1241 can be distributed more evenly at both ends of the support member 1241, thereby reducing the generation of unnecessary rotational torque.

[0091] In some embodiments, the protrusion 12511 is configured to be arched in an arc shape, and the limiting portion 1242 has an arc-shaped surface for abutting the elastic movable section 1251. With this configuration, as the limiting portion 1242 passes over the protrusion 12511 from the connecting portion 12512, the limiting portion 1242 and the protrusion 12511 can continuously abut each other, and the direction of the elastic force exerted by the protrusion 12511 on the limiting portion 1242 can gradually decrease rather than suddenly change, thereby making the rotation process of the support member 1241 smoother.

[0092] 15 to 17 , the above embodiment will be described below by taking as an example the case where the support member 1241 is in the storage position when the limiting portion 1242 is below the protrusion 12511 and is in the supporting position when the limiting portion 1242 is above the protrusion 12511 .

[0093] During the process of the support member 1241 opening from the storage position to the supporting position, the support member 1241 is first in the storage position, as shown in FIG15 . 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 supporting position, the limiting portion 1242 abuts against the protruding portion 12511. The elastic movable section 1251 is elastically deformed under the push of the limiting portion 1242, thereby generating an elastic force on the limiting portion 1242. The component of this elastic force in the direction of movement of the limiting portion 1242 is opposite to the direction of movement of the limiting portion 1242. This elastic force can generate a torque that prevents the support member 1241 from rotating, thereby limiting the support member 1241 from rotating toward the supporting position. The user can manually apply a rotational torque to the support member 1241 to overcome the elastic force of the protrusion 12511 on the limiting portion 1242, causing the limiting portion 1242 to gradually move upward over the protrusion 12511, and the support member 1241 to gradually rotate from the storage position to the supporting position. During the rotation process, the contact position between the limiting portion 1242 and the protrusion 12511 continuously changes. Because the limiting portion 1242 and the protrusion 12511 are arranged in an arc shape, the force between them is perpendicular to the tangent line of the contact point. The angle between the direction of the elastic force of the protrusion 12511 on the limiting portion 1242 and the direction of movement of the limiting portion 1242 gradually increases, and the direction of the elastic force gradually becomes parallel to the preset rotation axis of the support member 1241. During this process, the component of the elastic force of the protrusion 12511 in the direction of movement of the limiting portion 1242 also gradually decreases, that is, the torque that impedes the rotation of the support member 1241 gradually decreases. When the direction of the elastic force exerted by the protrusion 12511 on the limiting portion 1242 is perpendicular to the direction of movement of the limiting portion 1242, the component of the elastic force of the protrusion 12511 in the direction of movement of the limiting portion 1242 is zero. At this point, the support member 1241 rotates to the first transition position. Referring to FIG16 , the protrusion 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 protrusion 12511 and the limiting portion 1242 continues to change. After passing the first transition position, the angle between the elastic force direction of the protrusion 12511 on the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually decreases, and 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 protrusion 12511 on the limiting portion 1242 can generate a rotational torque that causes the support member 1241 to rotate to the supporting position. Even if the user no longer applies torque, the elastic force of the protrusion 12511 can push the limiting portion 1242 to move upward, and the support member 1241 can automatically rotate to the supporting position under the action of the torque of the first elastic member 125 (combined with Figure 17).

[0094] During the process of the support member 1241 closing from the supporting position to the storage position, the support member 1241 is first in the supporting position, as shown in FIG17 . When the support member 1241 is in the supporting position, the limiting portion 1242 is located above the protruding portion 12511. At this time, the protruding portion 12511 abuts against the upper connecting portion 12512. When the support member 1241 tends to rotate toward the storage position, the limiting portion 1242 abuts against the protruding portion 12511. The elastic movable section 1251 is elastically deformed under the push of the limiting portion 1242, thereby generating an elastic force on the limiting portion 1242. The component of this elastic force in the direction of movement of the limiting portion 1242 is opposite to the direction of movement of the limiting portion 1242. This elastic force can generate a torque that prevents the support member 1241 from rotating, thereby limiting the support member 1241 from rotating toward the storage position. The user can manually apply a rotational torque to support member 1241 to overcome the elastic force of protrusion 12511 on limiting portion 1242, causing limiting portion 1242 to gradually move downward over protrusion 12511, and supporting member 1241 to gradually rotate from the supporting position to the stowed position. During the rotation process, the contact position between limiting portion 1242 and protrusion 12511 continuously changes. Because limiting portion 1242 and protrusion 12511 are arranged in an arc shape, the force between them is perpendicular to the tangent line of the contact point. The angle between the direction of the elastic force of protrusion 12511 on limiting portion 1242 and the direction of movement of limiting portion 1242 gradually increases, and the direction of the elastic force gradually becomes parallel to the preset rotation axis of supporting member 1241. During this process, the component of the elastic force of protrusion 12511 in the direction of movement of limiting portion 1242 also gradually decreases, that is, the torque impeding the rotation of supporting member 1241 gradually decreases. When the direction of the elastic force exerted by the protrusion 12511 on the limiting portion 1242 is perpendicular to the direction of movement of the limiting portion 1242, the component of the elastic force of the protrusion 12511 in the direction of movement of the limiting portion 1242 is zero. At this point, the support member 1241 rotates to the first transition position. With reference to FIG16 , the protrusion 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 protrusion 12511 and the limiting portion 1242 continues to change. After passing the first transition position, the angle between the elastic force direction of the protrusion 12511 on the limiting portion 1242 and the movement direction of the limiting portion 1242 gradually decreases, and 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 protrusion 12511 on the limiting portion 1242 can generate a rotational torque that causes the support member 1241 to rotate to the storage position. Even if the user no longer applies torque, the elastic force of the protrusion 12511 can push the limiting portion 1242 to move downward, and the support member 1241 can automatically rotate to the storage position under the action of the torque of the first elastic member 125 (combined with Figure 15).
