[0013] 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.

[0014] 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.

[0015] The following description takes a TWS headset system as an example.

[0016] 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.

[0017] The charging box 10 can charge the earphones. When the earphones are accommodated in the receiving slot 1121, the earphones can be electrically connected to charge the earphones. For example, the receiving slot 1121 can be provided with charging contacts ( Figure 1The earphones are also provided with charging contacts (not shown). When the earphones are placed in the receiving 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 receiving slot 1121, the charging box 10 and the earphones are magnetically attracted to each other.

[0018] The charging box 10 may be provided with a prompt component, such as a display screen or an LED light, which can be used to prompt corresponding information, such as power level, etc. 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, or a Lightning interface.

[0019] The two earphones can be divided into a primary and a secondary earphone. The primary earphone can communicate with external devices, for example, via Bluetooth technology. External devices can be, for example, mobile phones, tablets, smart watches, laptops, etc. The secondary earphone can also communicate with the primary earphone. Data sent by the external device can be sent to the primary earphone and simultaneously sent to the secondary earphone via the primary earphone, ensuring that the primary and secondary earphones receive data as synchronously as possible.

[0020] For further details about the embodiment of the charging box 10 of the present application, please refer to the detailed description below.

[0021] Combine Figures 1 to 4 The embodiment of the present application provides a charging box 10 for earphones, which includes a box cover 12 and a box body 11. The box body 11 is used to accommodate earphones. The box body 11 is provided with a receiving groove 1121 for accommodating the earphones. The shape of the receiving groove 1121 is configured to imitate the shape of the earphones, so that the receiving groove 1121 can accommodate the earphones on the one hand, and on the other hand, when the earphones are placed in the receiving groove 1121, the movement of the earphones is restricted, thereby playing a positioning role.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] Specifically, combined Figures 2 to 3 , for example, 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. In the process of the box cover 12 changing from the closed position to the open position, first, combined with Figure 2 , the box cover 12 is in the closed position, and the elastic force vector generated by the second elastic member on the box cover 12 is located on the right side of the second rotation axis 120 (reference Figure 2The relative position relationship between F1 and the second rotation axis 120 in the middle), the cover 12 will be subjected to a counterclockwise torque. The elastic force of the second elastic member will hinder the opening of the 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 cover 12 to gradually open. In the process of gradual opening of the cover 12, the position of the elastic force vector generated by the second elastic member changes relative to the second rotation axis 120. When the cover 12 is opened 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 in the figure), that is, the second elastic member will not apply a torque to the cover 12. As the cover 12 continues to open, the elastic force vector generated by the second elastic member changes to the left side of the second rotation axis 120 (reference Figure 3 (the relative positional relationship between F2 and the second rotation axis 120 in FIG1 ) 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 still apply the clockwise torque to the lid 12, thereby promoting the 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.

[0026] Combine Figures 2 to 3 In the process of the lid 12 changing from the open position to the closed position, first, the Figure 3 , the box cover 12 is in the open position, at this time the elastic force vector generated by the second elastic member on the box cover 12 is located on the left side of the second rotation axis 120 (reference Figure 3 The relative position relationship between F2 and the second rotation axis 120 in the middle), the lid 12 will be 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. In the process of 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 in the figure), that is, the second elastic member will 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 changes to the right side of the second rotation axis 120 (reference Figure 2 (The relative positional relationship between F1 and the second rotation axis 120 in FIG1 ) causes the lid 12 to be subjected to a counterclockwise torque. 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 automatically close the lid 12. 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.

[0027] 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.

[0028] In some embodiments, combined Figure 5 and Figure 6 , the number of support positions is at least two, 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 the rotation from the storage position to different support positions are different. The support member 115 can be maintained at different support positions by limiting devices such as buckles, damping or magnetism, thereby forming first fulcrums with different positions at different support positions. Furthermore, the number of open positions is at least two, 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 the rotation from the closed position to different open positions are different. The box cover 12 can also be maintained at different open positions by limiting devices such as buckles, damping or magnetism, thereby forming second fulcrums with different positions at different open positions. In the above manner, the support member 115 and the box cover 12 can form first fulcrums and second fulcrums with different positions, and the first fulcrums and second fulcrums with different positions can support the mobile terminal at different angles, thereby adapting to the diverse support needs of users.

[0029] In some embodiments, combined Figures 1 to 3The box body 11 has a top 112 (or the inner lining of the box body 11). The top 112 is provided with a receiving groove 1121 for accommodating headphones. The receiving groove 1121 is located between the support member 115 and the rotation axis of the box cover 12, so as to receive the headphones through the top 112. The box cover 12 can cover the top 112 and the support member 115 when in the closed position, and expose the top 112 when in the open position. The support member 115 is rotatably connected to the top 112. The position of the support member 115 is spaced apart from the receiving groove 1121 to reduce the mutual influence between the support member 115 and the headphones.

[0030] 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.

[0031] In some embodiments, combined Figure 2 and Figure 3 The support member 115 has a free end away from its rotation axis. When the support member 115 is in the storage position, there is a hand-gripping space between its free end and the side wall of the accommodating groove 1121. The hand-gripping 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.

[0032] 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.

[0033] 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.

[0034] In some embodiments, further combined 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 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 rotated 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, when the charging box 10 is closed, the first magnetic member 1151 and the second magnetic member 123 can cooperate to 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 box cover 12 is closed and the support member 115 is in the supporting position, and the relative magnetic poles are the same. The first magnetic member 1151 and the second magnetic member 123 may not be arranged relative to each other, but the magnetic field generated by the first magnetic member 1151 is in the opposite direction of the magnetic flux lines of the second magnetic member 123 at 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 force between each other. In some embodiments, the magnet may include a metal alloy magnet, ferrite, etc. The metal alloy magnet may include neodymium iron boron, samarium cobalt, aluminum nickel cobalt, iron chromium cobalt, aluminum iron boron, iron carbon aluminum, or the like, or a combination of multiple thereof. The ferrite may include barium ferrite, steel ferrite, manganese ferrite, lithium manganese ferrite, or the like, or a combination of multiple thereof.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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 .

[0041] In some embodiments, combined Figure 3 The support member 115 is rotatably connected to the box body 11 around a first rotation axis 1150 and has a free end that is away from the first rotation axis 1150 and rotates around the first rotation axis 1150. The free end of the support member 115 approaches or moves away from the second rotation axis 120 during the rotation around the first rotation axis 1150. In the supporting state, the free end is further away from the second rotation axis 120 than in the stored state, and in the supporting state, it protrudes from the box body 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 box cover 12. For example, if the box cover 12 rotates clockwise to open, the support member 115 rotates counterclockwise to open. With this arrangement, when the box cover 12 is in the open position and the support member 115 is in the supporting position, the pressure exerted by the mobile terminal supported between the two tends to maintain the box cover 12 in the open position and the support member 115 in the supporting position.

[0042] In some embodiments, combined Figure 3The support member 115 can rotate around the first rotating shaft 1150 relative to the box body 11, and the first magnetic member 113 and the second magnetic member 114 are respectively located on both sides of the first rotating shaft 1150. The box body 11 is provided with a first limiting portion 116 and a second limiting portion 117, which are respectively located on both sides of the first rotating shaft 1150 and correspond to the first magnetic member 113 and the second magnetic member 114. Among them, 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, so as to cooperate with the first magnetic member 113 to keep 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, so as to cooperate with the second magnetic member 114 to keep 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In some embodiments, combined Figure 4The charging box 10 includes a first magnetic member 1151 and a second magnetic member 123. The first magnetic member 1151 is arranged on the support member 115, and the second magnetic member 123 is arranged 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 supporting position away from the storage position of the support member 115, so as to drive the support member 115 to rotate from the supporting 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 support member 115 is driven to rotate from the supporting position to the storage position through the magnetic repulsion between the second magnetic member 123 and the first magnetic member 1151. 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.

[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 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.

[0049] 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.

[0050] 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.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
