[Technical Field]

[0001] This application claims priority to Chinese patent applications filed on February 4, 2024, bearing application numbers 202420280528.8, 202410160739.2, and 202420280519.9, and entitled "Earphone Charging Case and Earphone System," "Earphone Charging Case and Earphone System," and "Earphone Charging Case and Earphone System," the contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of earphones, and more particularly to a charging case for earphones and an earphone system. [Background technology]

[0003] In daily life, the use of wireless earphones and mobile terminals such as mobile phones is becoming more and more popular, and the combination of wireless earphones and mobile phones has become a standard arrangement for people. In the related art, the charging case of a wireless earphone is only used to store and charge the earphones, and does not have the function of supporting a mobile terminal. Summary of the Invention

[0004] An embodiment of the present application provides an earphone charging case and an earphone system, where the charging case can support a mobile terminal when opened.

[0005] In a first aspect, an embodiment of the present application provides a charging case for earphones. The charging case for earphones includes a case body, a case cover, and a support member. The case body houses earphones. The case cover is rotatably connected to the case body and has an open position that opens the charging case. The support member is rotatably attached to the case body and is rotatable relative to the case body between a storage position and a support position. When in the support position, the support member protrudes from the case body, and when in the storage position, the support member is stored within the case body. When the support member is in the support position, a first support point is formed, and when the case cover is in the open position, a second support point is formed, and both the first support point and the second support point support a mobile terminal.

[0006] In a second aspect, an embodiment of the present application provides an earphone system, including an earphone and the charging case that houses the earphone.

[0007] The beneficial effects of the present application are as follows: Unlike the prior art, a rotatable support member is installed on the charging case, allowing the support member to rotate relative to the case body between a storage position and a support position. Therefore, when the charging case is opened, the support member can cooperate with the case cover to place a mobile terminal on the support member at the support position, and when the charging case is closed, the support member can be stored within the case body. This configuration allows the charging case to be used not only as a tool for storing and charging earphones, but also as a support member for the mobile terminal.

[0010] Hereinafter, the technical means of the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, but it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments, and all other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without any creative work fall within the scope of protection of the present application.

[0011] In the first embodiment, the configuration is as shown in FIGS.

[0012] An embodiment of the present application provides an earphone system. The earphone system includes a charging case 10 that houses the earphone, and the earphone. Specifically, the earphone system described in the embodiment of the present application may include at least two earphones. The earphone system may be, for example, a TWS (true wireless) earphone system, another earphone that needs to be charged by the charging case 10, a neck-mounted wireless earphone system, or a wired earphone system.

[0013] The following description will be given taking the earphone system as a TWS earphone system as an example.

[0014] A TWS earphone system may include a charging case 10 and two earphones. The charging case 10 accommodates the earphones and charges them after they are accommodated in the charging case 10. Preferably, the charging case 10 includes a case cover 12 and a case body 11 connected to each other. The case body 11 has two accommodation grooves 1121, and the number of accommodation grooves 1121 may be the same as the number of earphones. The accommodation grooves 1121 accommodate the earphones. The case cover 12 is rotatably / slidably connected to the case body 11 to selectively close the accommodation grooves 1121. For example, the case cover 12 is rotatably connected to the case body 11 via a rotation axis to achieve a flip design. For example, the case cover 12 can slide relative to the case body 11 through the cooperation of a slide rail and a slide block, further achieving a slide cover design.

[0015] The charging case 10 can charge the earphones, and when the earphones are placed in the receiving grooves 1121, the charging case 10 is electrically connected to the earphones and can further charge the earphones. For example, charging contacts (shown in FIG. 1 but not shown) may be installed in the receiving grooves 1121, and corresponding charging contacts (not shown) may also be installed on the earphones. When the earphones are placed in the receiving grooves 1121, the charging contacts of the earphones come into contact with the charging contacts of the charging case 10, achieving an electrical connection. Naturally, the charging case 10 can also wirelessly charge the earphones. The charging case 10 can be structurally and / or electrically connected to the earphones by magnetic attraction, and when the earphones are placed in the receiving grooves 1121, the charging case 10 is magnetically attracted to the earphones.

[0016] The charging case 10 may be provided with a display or LED lamp that displays corresponding information, such as battery level. The charging case 10 may be provided with a charging interface (not shown), such as a USB interface, a TYPE-C interface, a MIN-USB interface, or a Lighting interface. The two earphones can be divided into a primary earphone and a secondary earphone. The primary earphone can be connected to an external device for communication, for example, via Bluetooth technology. The external device may be, for example, a mobile phone, a tablet, a smartwatch, or a laptop. The secondary earphone can communicate with the primary earphone. Data transmitted from the external device is transmitted to the primary earphone and then transmitted from the primary earphone to the secondary earphone, allowing the primary and secondary earphones to receive data as synchronously as possible.

[0017] For further details regarding the embodiments of the charging case 10 of the present application, please refer to the detailed description below.

[0018] As shown in FIGS. 1 to 4 , an earphone charging case 10 according to an embodiment of the present application includes a case cover 12 and a case body 11. Case body 11 houses the earphone. Case body 11 is formed with a housing groove 1121 that houses the earphone. The shape of housing groove 1121 is arranged to follow the shape of the earphone, so that housing groove 1121 can house the earphone, and when the earphone is placed in housing groove 1121, it can limit movement of the earphone and serve to position it.

[0019] Case cover 12 is rotatably connected to case body 11 and can rotate relative to case body 11 between a closed position and an open position, thereby covering the earphones when in the closed position and exposing the earphones when in the open position. By installing case cover 12, the earphones are covered when placed inside case body 11, thereby providing protection for the earphones, reducing the possibility of the earphones falling out of case body 11 and reducing damage to the earphones due to dirt such as dust.

[0020] In some embodiments, the charging case 10 includes a second elastic member (not shown) that connects the case body 11 and the case cover 12 and drives the case cover 12 to rotate to the closed position when the case cover 12 rotates from the open position to the closed position. The second elastic member may be, for example, a torsion spring or a leaf spring, but is not particularly limited thereto. When the case cover 12 approaches the case body 11, the second elastic member applies a torque to the case cover 12 that promotes closing, thereby enabling the case cover 12 to automatically close when it approaches the case body 11. Furthermore, when the case cover 12 is in the closed position, the torque applied by the second elastic member acts to restrict the opening of the case cover 12, thereby reducing unexpected opening caused by movement or vibration of the case cover 12 and reducing the risk of the earphones accidentally falling off.

[0021] In some embodiments, the second elastic member is further configured to have a second transitional position in which the case cover 12 has a second transitional position between the open position and the closed position relative to the case body 11, and to elastically drive the case cover 12 to rotate to the open position when the case cover 12 rotates from the second transitional position to the open position, and to elastically drive the support member 115 to rotate to the closed position when the case cover 12 rotates from the second transitional position to the closed position. For example, assuming that the case body 11 is fixedly mounted and the case cover 12 rotates, the case cover 12 rotates around the second rotation axis 120 relative to the case body 11, thereby opening and closing the case cover 12 relative to the case body 11. During the process of opening and closing the case cover 12 due to the elastic force applied to the case cover 12 by the second elastic member, the position of the elastic force vector relative to the second rotation axis 120 may change, thereby causing a change in the direction of the torque applied to the case cover 12 by the second elastic member, which in turn changes the rotation tendency of the case cover 12 during the opening and closing process, thereby realizing the change in the elastic driving direction.

[0022] Specifically, as shown in FIGS. 2 and 3 , the second elastic member is located below the second rotation shaft 120, the rotation shaft of the case cover 12 and the case body 11 is located on the right side of the charging case 10, and the case cover 12 can be opened by rotating clockwise and closed by rotating counterclockwise. In the process of the case cover 12 changing from the closed position to the open position, first, as shown in FIG. 2 , when the case cover 12 is in the closed position, the elastic force vector generated by the second elastic member on the case cover 12 is located on the right side of the second rotation shaft 120 (see the relative positional relationship between F1 and the second rotation shaft 120 in FIG. 2 ), and the case cover 12 is subjected to a counterclockwise torque. If the elastic force of the second elastic member prevents the case cover 12 from opening, the user can manually apply a clockwise torque to overcome the torque generated by the second elastic member, thereby driving the case cover 12 to gradually open. As the case cover 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 case cover 12 opens to the second transitional position, the elastic force vector generated by the second elastic member is directed toward the center of the rotation axis (not shown), i.e., the second elastic member does not apply torque to the case cover 12. As the case cover 12 continues to open, the elastic force vector generated by the second elastic member changes to the left of the second rotation axis 120 (see the relative positional relationship between F2 and the second rotation axis 120 in FIG. 3 ). When the case cover 12 is subjected to a clockwise torque, the second elastic member applies a clockwise torque to the case cover 12, thereby promoting the rotation of the case cover 12 to the open position, even without the user applying clockwise torque. In other words, after the case cover 12 passes through the second transitional position, the torque applied by the second elastic member can promote the case cover 12 to open automatically.

[0023] As shown in FIGS. 2 and 3 , when the case cover 12 is changing from the open position to the closed position, as shown in FIG. 3 , when the case cover 12 is in the open position, the elastic force vector generated by the second elastic member on the case cover 12 is located to the left of the second rotation shaft 120 (see the relative positional relationship between F2 and the second rotation shaft 120 in FIG. 3 ), and the case cover 12 is subjected to a clockwise torque. If the elastic force of the second elastic member prevents the case cover 12 from closing, the user can manually apply a counterclockwise torque to overcome the torque generated by the second elastic member, thereby driving the case cover 12 to gradually close. As the case cover 12 gradually closes, the position of the elastic force vector generated by the second elastic member changes relative to the second rotation shaft 120. When the case cover 12 is closed to the second transitional position, the elastic force vector generated by the second elastic member is directed toward the center of the rotation shaft (not shown), i.e., the second elastic member does not apply torque to the case cover 12. As the case cover 12 continues to close, the elastic force vector generated by the second elastic member shifts to the right of the second rotation shaft 120 (see the relative positional relationship between F1 and the second rotation shaft 120 in FIG. 2 ). When the case cover 12 is subjected to a counterclockwise torque, the second elastic member applies a counterclockwise torque to the case cover 12, thereby promoting rotation of the case cover 12 to the closed position, even without the user applying a counterclockwise torque. In other words, after the case cover 12 passes through the second transitional position, the torque applied by the second elastic member can promote automatic closure of the case cover 12. Furthermore, after the case cover 12 is closed, the torque applied by the second elastic member can prevent the case cover 12 from opening, thereby preventing unexpected opening of the case cover 12.

[0024] In some embodiments, the charging case 10 further includes a support member 115 that is rotatably mounted on the case body 11 and is rotatable relative to the case body 11 between a storage position and a support position, so that the support member 115 at least partially protrudes from the case body 11 when in the support position and is stored in the case body 11 when in the storage position. The case cover 12 covers the support member 115 when in the closed position and exposes the support member 115 when in the open position. The support member 115 and the case cover 12 together form a support area on which a mobile terminal is placed when in the support position or the open position, so that when the mobile terminal is placed in the support area, the protruding portions of the case cover 12 and the support member 115 together support the mobile terminal. By providing the support member 115, the charging case 10 can not only serve as a tool for storing earphones but also as a support member 115 for the mobile terminal, which is convenient for users to use. Specifically, a first fulcrum is formed when the support member 115 is in the support position, and a second fulcrum is formed when the case cover 12 is in the open position, and both the first fulcrum and the second fulcrum support the mobile terminal.

[0025] In some embodiments, as shown in FIGS. 5 and 6 , the number of support positions is at least two, and the support member 115 rotatably passes through at least two support positions in sequence from the storage position, with different rotation angles corresponding to rotation from the storage position to the different support positions. The support member 115 is maintained in each of the different support positions by a position limiting device, such as a locking device, a damping device, or a magnetic attraction device, thereby forming different first fulcrum positions in the different support positions. Furthermore, the number of open positions is at least two, and the case cover 12 rotatably passes through at least two open positions in sequence from the closed position, with different rotation angles corresponding to rotation from the closed position to the different open positions. The case cover 12 is maintained in each of the different open positions by a position limiting device, such as a locking device, a damping device, or a magnetic attraction device, thereby forming different second fulcrum positions in the different open positions. Using the above method, the support member 115 and the case cover 12 can form a first fulcrum and a second fulcrum at different positions, and the first fulcrum and the second fulcrum at different positions can support the mobile terminal at different angles, thereby adapting to the various support needs of users.

[0026] In some embodiments, as shown in FIGS. 1 to 3 , case body 11 has top 112 (also called the liner of case body 11), and top 112 is formed with accommodating grooves 1121 for accommodating earphones. Accommodating grooves 1121 are located between support member 115 and the rotation axis of case cover 12, allowing top 112 to accommodate earphones. Case cover 12 can close top 112 and cover support member 115 when in the closed position, and expose top 112 when in the open position. Support member 115 is rotatably connected to top 112. A certain distance is maintained between the installation position of support member 115 and accommodating groove 1121, thereby reducing the mutual influence between support member 115 and the placement of earphones.

[0027] In some embodiments, the top portion 112 is formed with a mounting groove 1122, and the support member 115 is rotatably installed in the mounting groove 1122. When the support member 115 is in the supporting position, the support member 115 is at least partially located outside the mounting groove 1122 so as to cooperate with the case cover 12 to form a support area that supports the mobile terminal. When the support member 115 is in the storage position, the support member 115 is housed in the mounting groove 1122 so as to avoid interference with the case cover 12 and the earphones.

[0028] In some embodiments, as shown in FIGS. 2 and 3, the support member 115 has a free end away from its rotation axis, and when in the storage position, there is a finger space between the free end and the side wall of the storage groove 1121 for a user to rotate the support member 115 and drive the support member 115 to rotate from the storage position to the support position.

[0029] In some embodiments, the support member 115 is configured to limit its rotation when in the support position so that it rotates in a direction from the storage position to the support position. Specifically, when the support member 115 is in the support position, the support member 115 is prone to rotate due to the influence of vibration and movement of the case body 11, and eventually rotates to the storage position, making it unable to effectively support the mobile device. Therefore, by limiting the support member 115 to rotate in a direction from the storage position to the support position when the support member 115 is installed in the support position, the support member 115 can be stably positioned in the support position, improving the stability of supporting the mobile device.

[0030] Specifically, when the support member 115 is in the support position, it abuts against the support member 115 in the rotation direction of the case body 11 from the support position to the storage position, thereby restricting the rotation of the support member 115 in the rotation direction from the support position to the storage position. For example, the case body 11 may be provided with a position limiting structure (a position limiting protrusion, a position limiting leaf spring, etc.), and the support member 115 can reach the support position by exceeding the position limiting structure with a large torque during the process of rotation by the user. When the support member 115 is in the support position, the position limiting structure abuts against the support member 115, thereby restricting the rotation of the support member 115 and allowing the support member 115 to stably support the mobile terminal. During the process of rotating the support member 115 to the storage position, the user can bias the support member 115, thereby overcoming the position limiting biasing force of the position limiting structure and rotating to the storage position.

[0031] 4 , in some embodiments, the charging case 10 includes a first magnetic member 1151 and a second magnetic member 123, where the first magnetic member 1151 is attached to the support member 115 and the second magnetic member 123 is attached to the case 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 support position and the case cover 12 is changing from the open position to the closed position. When the case cover 12 rotates 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 support position to the storage position. With this arrangement, the first magnetic member 1151 and the second magnetic member 123 cooperate to automatically rotate the support member 115 from the support position to the storage position during the process of closing the charging case 10, eliminating the need for active operation by the user and improving the convenience of using the support member 115. When the support member 115 is in the support position during the closing process of the case cover 12, the first magnetic member 1151 and the second magnetic member 123 may be positioned opposite each other, and their opposing magnetic poles may be the same. The first magnetic member 1151 and the second magnetic member 123 do not necessarily need to be positioned opposite each other, but a repulsive force is generated because the direction of the magnetic field generated by the first magnetic member 1151 in the second magnetic member 123 is opposite to the direction of the magnetic field lines of the second magnetic member 123. A magnetic member refers to an element capable of generating a magnetic field, such as a magnet. The magnetic element may have a magnetic field and generate a magnetic force between the magnetic members. In some embodiments, the magnet may include a metal alloy magnet, ferrite, or the like. The metal alloy magnet may include neodymium-iron-boron, samarium-cobalt, alnico, iron-chromium-cobalt, aluminum-iron-boron, iron-carbon-aluminum, or the like, or a combination of two or more thereof. The ferrite may include barium ferrite, steel ferrite, magnesium manganese ferrite, lithium manganese ferrite, or the like, or a combination of two or more thereof.

[0032] In some embodiments, when the support member 115 is in the supporting position, the support member 115 is configured to limit itself to rotating along a rotational direction from the storage position to the supporting position. Specifically, the charging case 10 includes a first magnetically attractive member 113 installed on the case body 11 and spaced apart from the support member 115. The first magnetically attractive member 1151 and the first magnetically attractive member 113 are configured to magnetically attract each other so as to hold the support member 115 in the supporting position when the support member 115 is in the supporting position. The first magnetically attractive member 113 may be a magnetic member such as a magnet, or may be a soft magnetic material. The soft magnetic material may include a metal material, a metal alloy, a metal oxide material, an amorphous metal material, etc., such as iron, an iron-silicon based alloy, an iron-aluminum based alloy, a nickel-iron based alloy, an iron-cobalt based alloy, a low-carbon steel, a silicon steel plate, a silicon steel plate, and a ferrite. When the first magnetically attractive member 113 is a magnetic member and the support member 115 is in the support position, the magnetic pole of the first magnetically attractive member 113 may be placed opposite the first magnetic member 1151. The first magnetic member 1151 and the first magnetically attractive member 113 do not have to be placed opposite each other, but a repulsive force is generated by the magnetic field generated by the first magnetically attractive member 113 because the direction of the magnetic field in the first magnetic member 1151 is opposite to the direction of the magnetic field lines of the first magnetic member 1151.

[0033] In one embodiment, the second magnetic member 123 and the first magnetically attractive member 113 are configured to magnetically attract each other when the case cover 12 is in the closed position so as to hold the case cover 12 in the closed position. The first magnetically attractive member 113 may be a soft magnetic material, thereby generating an attractive force with the second magnetic member 123. The first magnetically attractive member 113 may be a magnetic material such as a magnet, and when the case cover 12 is in the closed position, the first magnetically attractive member 113 and the second magnetic member 123 are disposed opposite to each other and have opposite magnetic poles, thereby generating an attractive force.

[0034] In some embodiments, the magnetic attraction assembly further includes a second magnetic attraction member 114 mounted on the case body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetic attraction member 114 are configured to magnetically attract each other when the support member 115 is in the storage position so as to hold the support member 115 in the storage position. By providing the second magnetic attraction member 114, the support member 115 can be stably positioned in the storage position, reducing the possibility of the support member 115 being rotated unexpectedly by the user and reducing collisions between the support member 115 and the case body 11, the case cover 12, etc.

[0035] Specifically, when the support member 115 is in the support position, the magnetic attraction force between the first magnetic member 1151 and the first magnetic attraction member 113 is greater than the magnetic attraction force between the first magnetic member 1151 and the second magnetic attraction member 114. When the support member 115 is in the storage position, the magnetic attraction force between the first magnetic member 1151 and the second magnetic attraction member 114 is greater than the magnetic attraction force between the first magnetic member 1151 and the first magnetic attraction member 113.

[0036] In short, since the first magnetic member 1151 and the second magnetic member 123 are required to generate a repulsive force, both may be magnets, and since the first magnetic attraction member 113 and the second magnetic attraction member 114 and the first magnetic member 1151 and the second magnetic member 123 both generate an attractive force, the first magnetic attraction member 113 and the second magnetic attraction member 114 may be magnets or may be made of a soft magnetic material.

[0037] In some embodiments, the first magnetic member 1151 is embedded in the support member 115 or is formed integrally with the support member 115 as a mold core during the manufacture of the support member 115. In some embodiments, the second magnetic member 123 is embedded in the case cover 12 so as not to be visible on the outer surface of the case cover 12. For example, the case cover 12 may include an outer case cover 121 and an inner case cover 122 (also called liners of the case cover 12), where the outer case cover 121 and / or the inner case cover 122 are rotatably connected to the case body 11. The inner case cover 122 is disposed inside the outer case cover 121, and when the case cover 12 is in the closed state, the inner case cover 122 is located between the outer case cover 121 and the case body 11, and the second magnetic member 123 is disposed between the outer case cover 121 and the inner case cover 122. In some embodiments, the first magnetically attractive member 113 is embedded in the case body 11 so as not to be visible on the outer surface of the case body 11. For example, the case body 11 includes a housing and a top 112 (or called a liner of the case body 11), and the top 112 has an accommodating groove 1121 formed therein for accommodating the earphone, and the first magnetic attraction member 113 is installed between the housing and the top 112.

[0038] 3 , the support member 115 may be rotatably connected to the case body 11 around a first rotation axis 1150 and may have a free end that is spaced apart from the first rotation axis 1150 and rotates around the first rotation axis 1150. The free end of the support member 115 approaches the second rotation axis 120 and moves away from the second rotation axis 120 during the process of rotating around the first rotation axis 1150. In the supporting state, the free end is spaced apart from the second rotation axis 120 more than in the storage state, and in the supporting state, the free end protrudes from the case body 11 to support the mobile terminal. In other words, the opening direction of the support member 115 and the opening direction of the case cover 12 are opposite. For example, when the case cover 12 is rotated clockwise to open, the support member 115 is rotated counterclockwise to open. By installing it in this manner, when the case cover 12 is in the open position and the support member 115 is in the support position, the direction of pressure on the mobile terminal supported between them tends to maintain the case cover 12 in the open position and the support member 115 in the support position.

[0039] 3 , the support member 115 is rotatable relative to the case body 11 around a first rotation axis 1150, and the first magnetically attractive member 113 and the second magnetically attractive member 114 are located on either side of the first rotation axis 1150. The case body 11 is provided with a first position limiting portion 116 and a second position limiting portion 117, which are located on either side of the first rotation axis 1150 and correspond to the first magnetically attractive member 113 and the second magnetically attractive member 114, respectively. When the support member 115 rotates from the storage position to the support position, the first position limiting portion 116 abuts against the support member to cooperate with the first magnetically attractive member 113 to hold the support member 115 in the support position. When the support member 115 rotates from the supporting position to the retracted position, the second position limiting portion 117 abuts against the support member 115 so as to cooperate with the second magnetically attractive member 114 to hold the support member in the retracted position. As the support member 115 rotates in cooperation with the first magnetically attractive member 113 and the second magnetically attractive member 114 via the first magnetic member 1151, the support member 115 is continuously subjected to torque. When the support member 115 rotates to the supporting position or the retracted position, it is necessary to balance the torque received by the support member 115 and limit further rotation of the support member 115. By providing the first position limiting portion 116 and the second position limiting portion 117, further rotation of the support member 115 can be prevented during the supporting and retracting processes.

[0040] Furthermore, a mounting groove 1122 is formed in the case body 11, and the support member 115 is rotatably installed in the mounting groove 1122. When in the supporting position, the support member 115 is at least partially located outside the mounting groove 1122, and when in the storage position, the support member 115 is housed in the mounting groove 1122. A portion of the side wall of the mounting groove 1122 is formed as a first position limiting portion 116, and a bottom wall of the mounting groove is formed as a second position limiting portion 117. When the support member 115 rotates to the supporting position, the support member 115 directly abuts against a portion of the side wall of the mounting groove 1122, restricting further rotation of the support member 115, and therefore the portion of the side wall of the mounting groove 1122 is formed as the first position 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 groove 1122 to limit further rotation of the support member 115, so that the bottom wall of the mounting groove 1122 can be formed as a second position limiting portion 117.

[0041] In some embodiments, the charging case 10 includes a first elastic member (not shown), which connects the case body 11 and the support member 115, the support member 115 having a first transitional position between a support position and a storage position relative to the case body 11, and is configured to elastically drive the support member 115 to rotate to the support position when the support member 115 rotates from the first transitional position to the support position, and to elastically drive the support member 115 to rotate to the storage position when the support member 115 rotates from the first transitional position to the storage position. For example, in a case where the case body 11 is fixedly placed and the support member 115 rotates, the support member 115 rotates relative to the case body 11 along the first rotation axis 1150, thereby supporting or storing the support member 115 relative to the case body 11. During the process of opening and closing the support member 115 due to the elastic force applied by the first elastic member to the support member 115, the position of the elastic force vector relative to the first rotation axis 1150 can change, thereby causing a change in the direction of the torque applied by the first elastic member to the support member 115.Furthermore, during the process of opening and closing the support member 115, the rotation tendency of the support member 115 changes, thereby realizing the change in the above-mentioned elastic driving direction.

[0042] Specifically, for example, the first elastic member is located below the first rotation shaft 1150 and is located at the left end of the support member 115 when in the storage position, and the support member 115 can be stored by rotating clockwise and can be supported by rotating counterclockwise. In the process of the support member 115 changing from the storage position to the support position, when the support member 115 is in the storage position, the elastic force vector generated by the first elastic member on the support member 115 is located to the left of the first rotation shaft 1150, and the torque received by the support member 115 causes the support member 115 to rotate clockwise. If the elastic force of the first elastic member prevents the support member 115 from opening, the user can manually apply counterclockwise torque to overcome the torque generated by the first elastic member, thereby gradually driving the support member 115 to 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 transitional position, the elastic force vector generated by the first elastic member points toward the center of the rotation axis, i.e., 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 changes to the right of the first rotation axis 1150, and the support member 115 is subjected to a counterclockwise torque. Even if the user does not apply a counterclockwise torque, the first elastic member can apply a counterclockwise torque to the support member 115 to promote the rotation of the support member 115 to the support position. In other words, after the support member 115 passes through the first transitional position, the torque applied by the first elastic member can promote the support member 115 to automatically rotate to the support position.

[0043] During the process of the support member 115 changing from the supporting position to the retracted position, when the support member 115 is in the supporting position, 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. If the elastic force of the first elastic member prevents the support member 115 from retracting, 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 retract. During the process of the support member 115 gradually retracting, 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 retracted to the first transitional position, the elastic force vector generated by the first elastic member is directed toward the center of the rotation axis, i.e., the first elastic member does not apply torque to the support member 115. As the support member 115 continues to retract, the elastic force vector generated by the first elastic member changes to the left of the first rotation axis 1150, and when the support member 115 is subjected to a clockwise torque, the first elastic member can apply a clockwise torque to the support member 115 to promote rotation of the support member 115 to the retracted position, even without the user applying a clockwise torque. In other words, after the support member 115 passes through the first transitional position, the torque applied by the first elastic member can promote the support member 115 to retract automatically.

[0044] In some embodiments, as shown in FIG. 4 , the charging case 10 includes a first magnetic member 1151 and a second magnetic member 123. The first magnetic member 1151 is attached to the support member 115, and the second magnetic member 123 is attached to the case cover 12. Because the first magnetic member 1151 is closer to the second rotation axis 120 than the second magnetic member 123, the second magnetic member 123 can apply a repulsive force to the first magnetic member 1151 on the side of the support member 115 that is away from the storage position, thereby driving the support member 115 to rotate from the support position to the storage position. The first magnetic member 1151 and the second magnetic member 123 are configured to magnetically repel each other when the support member 115 is in the support position and the case cover 12 is in the closed position. When the case cover 12 rotates 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 support position to the storage position. By arranging them in this manner, the first magnetic member 1151 and the second magnetic member 123 cooperate to automatically rotate the support member 115 from the supporting position to the storage position during the process of closing the charging case 10, eliminating the need for active operation by the user and improving the convenience of using the support member 115. The first magnetic member 1151 and the second magnetic member 123 may be arranged to face each other when the support member 115 is in the supporting position during the process of closing the case cover 12, and the facing magnetic poles are the same. The first magnetic member 1151 and the second magnetic member 123 do not have to be arranged to face each other, but a repulsive force is generated because 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 field lines of the second magnetic member 123.

[0045] In some embodiments, when the support member 115 is in the supporting position, the support member 115 is configured to limit itself to rotating along a rotational direction from the storage position to the supporting position. Specifically, the charging case 10 includes a first magnetically attractive member 113 disposed on the case body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the first magnetically attractive member 113 are configured to magnetically attract each other to hold the support member 115 in the supporting position when the support member 115 is in the supporting position. Because the first magnetic member 1151 is closer to the second rotation shaft 120 than the first magnetically attractive member 113, the first magnetically attractive member 113 generates an attractive force with the first magnetic member 1151 on the supporting position side of the support member 115 away from the storage position, thereby stabilizing the support member 115 in the supporting position.

[0046] In some embodiments, when the case cover 12 is in the closed position, it closes the case body 11 along a predetermined direction, and when the case cover 12 is in the closed position, the second magnetic member 123 and the first magnetic attraction member 113 are spaced apart along the predetermined direction and magnetically attract each other so as to hold the case cover 12 in the closed position, and the predetermined direction may be the thickness direction of the charging case 10.

[0047] Based on the above embodiment, the charging case 10 includes a second magnetically attractive member 114 installed on the case body 11 and spaced apart from the support member 115. The first magnetic member 1151 and the second magnetically attractive member 114 are configured to magnetically attract each other when the support member 115 is in the storage position so as to hold the support member 115 in the storage position. By installing the second magnetically attractive member 114, the support member 115 can be stably positioned in the storage position, which reduces the possibility of the support member 115 rotating unexpectedly by the user and reduces collisions between the support member 115 and the case body 11, the case cover 12, etc.

[0048] Example 2 is as shown in FIGS.

[0049] An embodiment of the present application provides an earphone system. The earphone system includes a charging case 10 and earphones. The charging case 10 accommodates the earphones and charges them after they are accommodated in the charging case 10. Preferably, the charging case 10 includes a case cover 11 and a case body 12 that are connected to each other. The case body 12 has two accommodation grooves 122, and the number of accommodation grooves 122 may be the same as the number of earphones. The accommodation grooves 122 accommodate the earphones. The case cover 11 is rotatably / slidably connected to the case body 12 to selectively close the accommodation grooves 122. For example, the case cover 11 is rotatably connected to the case body 12 via a rotation axis to achieve a flip design. For example, the case cover 11 can slide relative to the case body 12 through the cooperation of a slide rail and a slide block, further achieving a slide-cover design.

[0050] The charging case 10 can charge the earphones. When the earphones are placed in the receiving grooves 122, the charging case 10 is electrically connected to the earphones and can charge the earphones. For example, charging contacts (shown in FIG. 7 but not shown) may be installed in the receiving grooves 122, and corresponding charging contacts (not shown) may also be installed on the earphones. When the earphones are placed in the receiving grooves 122, the charging contacts of the earphones come into contact with the charging contacts of the charging case 10, achieving an electrical connection. Of course, the charging case 10 can also wirelessly charge the earphones. The charging case 10 can be structurally and / or electrically connected to the earphones using a magnetic attraction method. When the earphones are placed in the receiving grooves 122, the charging case 10 is magnetically attracted to the earphones. The two earphones can be divided into a primary earphone and a secondary earphone. The primary earphone can be connected to an external device for communication, for example, via Bluetooth technology. The external device can be, for example, a mobile phone, a tablet, a smartwatch, a laptop, etc. The secondary earphone can communicate with the primary earphone, and data transmitted from the external device is transmitted to the primary earphone and then transmitted by the primary earphone to the secondary earphone, so that the primary and secondary earphones can receive data as synchronously as possible.

[0051] For further details regarding the embodiments of the charging case 10 of the present application, please refer to the detailed description below.

[0052] As shown in FIG. 7 , an embodiment of the present application provides a charging case 10 for earphones. The charging case 10 includes a case body 12, a case cover 11, and a support assembly 124. The case body 12 houses the earphones, and is formed with a housing groove 122 for housing the earphones. The housing groove 122 is configured to conform to the shape of the earphones, so that the housing groove 122 can house the earphones and, when the earphones are placed in the housing groove 122, can limit movement of the earphones and provide a positioning function. Components that manage the input and output of power and charge the earphones, such as a battery and a power control panel, may be installed inside the case body 12.

[0053] Case cover 11 is rotatably connected to case body 12 and can rotate relative to case body 12 between a closed position and an open position, thereby covering the earphones when in the closed position and exposing the earphones when in the open position. By installing case cover 11, the earphones are covered when placed inside case body 12, thereby providing protection for the earphones, reducing the possibility of the earphones falling out of case body 12 and reducing damage to the earphones due to dirt such as dust.

[0054] As shown in FIGS. 8 and 11 to 13, the support assembly 124 includes a support member 1241 and a first elastic member 125. The support member 1241 is rotatably mounted on the case body 12 and is rotatable relative to the case body 12 between a storage position and a support position. When the support member 1241 is in the support position, it at least partially protrudes from the case body 12. When the support member 1241 is in the support position and the case cover 11 is in the open position, the protruding portion of the support member 1241 and the case cover 11 are spaced apart from each other and together support the mobile terminal. When the support member 1241 is in the storage position, it is housed in the case body 12, preventing the support member 1241 from interfering with the case cover 11 or earphones and reducing the space occupied by the support member 1241. The first elastic member 125 connects the support member 1241 to the case body 12 and elastically restrains 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 hold the support member 1241 in the storage position or the support position, and can also provide a force to automatically rotate the support member 1241 to the storage position or the support position. When the support member 1241 is in the support position, a first fulcrum is formed, and when the case cover 11 is in the open position, a second fulcrum is formed, and the first and second fulcrums together support the mobile terminal. Preferably, the support member 1241 may cooperate with the case body 12 to form an intermediate support position during the rotation process, and when in the intermediate position, a first fulcrum at a different position may be formed. When the case cover 11 is in the opening process, the case body 12 may cooperate with the case body 12 to form an intermediate open position, and when in the intermediate open position, a second fulcrum at a different position may be formed. According to the above method, the positions of the first and second fulcrums can be changed to support the mobile terminal at different angles.

[0055] 8 , the case body 12 has a mounting groove 123, and the case cover 11 covers the mounting groove 123 when in the closed position and exposes the mounting groove 123 when in the open position. The support member 1241 is rotatably installed in the mounting groove 123, and when in the supporting position, at least partially protrudes from the mounting groove 123 to cooperate with the case cover 11 to support the mobile terminal, and when in the storing position, the support member 1241 is located within the mounting groove 123 to conceal and store the support member 1241 and reduce the volume protruding from the surface of the case body 12.

[0056] Specifically, the case body 12 includes a housing and an upper wall (shown in FIG. 8 but not labeled). The above-mentioned mounting groove 123 is formed in the upper wall, and the support member 1241 is rotatably installed in the mounting groove 123. When in the support position, the support member 1241 is at least partially located outside the mounting groove 123, and when in the storage position, the support member 1241 is housed in the mounting groove 123. Preferably, the support member 1241 has a support portion 1243 spaced from its rotation axis, and when in the storage position, there is a finger-hold space (shown in FIG. 9 but not labeled) between the support portion 1243 and the side wall of the mounting groove 123 that allows a user to rotate the support member 1241 and drive the support member 1241 to rotate from the storage position to the support position.

[0057] The charging case 10 further includes a second elastic member 126 connecting the case body 12 and the case cover 11, and the second elastic member 126 has a second transitional position in which the case cover 11 is between the open position and the closed position relative to the case body 12, and is configured to elastically drive the case cover 11 to rotate to the open position when the case cover 11 rotates from the second transitional position to the open position, and to elastically drive the case cover 11 to rotate to the closed position when the case cover 11 rotates from the second transitional position to the closed position.

[0058] For example, when the case body 12 is fixedly placed and the case cover 11 rotates, the case cover 11 rotates relative to the case body 12 along the first rotation shaft 111, thereby opening and closing the case cover 11 relative to the case body 12. In the process of opening and closing the case cover 11 due to the elastic force applied to the case cover 11 by the second elastic member 126, the position of the elastic force vector relative to the first rotation shaft 111 can change, which causes a change in the direction of the torque applied to the case cover 11 by the second elastic member 126. Furthermore, in the process of opening and closing, the rotation tendency of the case cover 11 changes, thereby realizing the change in the elastic driving direction.

[0059] 9 and 10 , the second elastic member 126 is located below the first rotating shaft 111, the rotating shaft of the case cover 11 and the case body 12 is located on the right side of the charging case 10, and the case cover 11 can be opened by rotating clockwise and closed by rotating counterclockwise. In the process of the case cover 11 changing from the closed position to the open position, when the case cover 11 is in the closed position, the elastic force vector generated by the second elastic member 126 on the case cover 11 is located to the right of the first rotating shaft 111 (see F1 in FIG. 9 ), and the case cover 11 is subjected to a counterclockwise torque. If the elastic force of the second elastic member 126 prevents the case cover 11 from opening, the user can manually apply a clockwise torque to overcome the torque generated by the second elastic member 126, thereby driving the case cover 11 to gradually open. As the case cover 11 gradually opens, the position of the elastic force vector generated by the second elastic member 126 changes relative to the first rotation shaft 111. When the case cover 11 opens to the second transitional position, the elastic force vector generated by the second elastic member 126 is directed toward the center of the rotation shaft (not shown). That is, the second elastic member 126 does not apply torque to the case cover 11. As the case cover 11 continues to open, the elastic force vector generated by the second elastic member 126 changes to the left of the first rotation shaft 111 (see F2 in FIG. 10 ). When the case cover 11 is subjected to a clockwise torque, the second elastic member 126 applies a clockwise torque to the case cover 11, thereby promoting the rotation of the case cover 11 to the open position, even without the user applying clockwise torque. In other words, after the case cover 11 passes through the second transitional position, the torque applied by the second elastic member 126 can promote the case cover 11 to open automatically.

[0060] 9, when the case cover 11 is in the open position, the elastic force vector generated by the second elastic member 126 on the case cover 11 is located to the left of the first rotation shaft 111 (see the relative positional relationship between F2 and the first rotation shaft 111 in FIG. 9), and the case cover 11 is subjected to a clockwise torque. If the elastic force of the second elastic member 126 prevents the case cover 11 from closing, the user can manually apply a counterclockwise torque to overcome the torque generated by the second elastic member 126, thereby driving the case cover 11 to gradually close. As the case cover 11 is gradually closed, the position of the elastic force vector generated by the second elastic member 126 changes relative to the first rotating shaft 111. When the case cover 11 is closed to the second transitional position, the elastic force vector generated by the second elastic member 126 is directed toward the center of the rotating shaft (not shown), i.e., the second elastic member 126 does not apply torque to the case cover 11. As the case cover 11 continues to close, the elastic force vector generated by the second elastic member 126 changes to the right of the first rotating shaft 111 (see the relative positional relationship between F1 and the first rotating shaft 111 in FIG. 8 ). When the case cover 11 is subjected to a counterclockwise torque, the second elastic member 126 can apply a counterclockwise torque to the case cover 11 to promote the rotation of the case cover 11 to the closed position, even if the user does not apply a counterclockwise torque. In other words, after the case cover 11 passes through the second transitional position, the torque applied by the second elastic member 126 can encourage the case cover 11 to close automatically. Also, after the case cover 11 is closed, the torque applied by the second elastic member 126 can prevent the case cover 11 from opening, thereby preventing the case cover 11 from opening unexpectedly.

[0061] In some embodiments, the first elastic member 125 is configured to elastically restrain the support member 1241 in the storage position when the support member 1241 is in the storage position, and to elastically restrain the support member 1241 in the support position when the support member 1241 is in the support position. Specifically, the support member 1241 is rotatably connected to the case body 12 and has a rotation shaft. The first elastic member 125 may be installed so that the vector direction of the elastic force changes as the position of the support member 1241 changes as the support member 1241 rotates. For example, when the case body 12 is in the storage position, by setting the positional relationship between the vector direction of the first elastic member 125 and the rotation shaft, it is possible to receive a torque that prevents the support member 1241 from being opened from the storage position. When the user applies an external force to open the support member 1241, the position of the first elastic member 125 also changes relatively, and when the support member 1241 is in the support position, the first elastic member 125 receives a torque that prevents the support member 1241 from being stored from the support position by setting the positional relationship between the vector direction of the first elastic member 125 and the rotation axis portion.

[0062] In some embodiments, as shown in FIGS. 11 to 13 , the first elastic member 125 is configured to have a first transitional position (as shown in FIG. 12 ) in which the support member 1241 is located between the support position (as shown in FIG. 13 ) and the storage position (as shown in FIG. 5 ) relative to the case body 12. When the support member 1241 rotates from the first transitional position to the support position, the first elastic member 125 elastically drives the support member 1241 to rotate to the support position, thereby elastically restraining the support member 1241 at the support position. When the support member 1241 rotates from the first transitional position to the storage position, the first elastic member 125 elastically drives the support member 1241 to rotate to the storage position, thereby elastically restraining the support member 1241 at the storage position. In other words, when the support member 1241 is located before or after the first transitional position, the direction of the torque applied by the first elastic member 125 to the support member 1241 changes.

[0063] For example, in a case where the case body 12 is fixedly placed and the support member 1241 rotates, the support member 1241 rotates relative to the case body 12 along the second rotation shaft 127 (or called a predetermined rotation shaft), thereby supporting or storing the support member 1241 relative to the case body 12. In the process of opening or closing the support member 1241 due to the elastic force applied by the first elastic member 125 to the support member 1241, the position of the elastic force vector relative to the second rotation shaft 127 can change, thereby causing a change in the direction of the torque applied by the first elastic member 125 to the support member 1241. Furthermore, in the process of opening or closing the support member 1241, the rotation tendency of the support member 1241 changes, thereby realizing the change in the elastic driving direction.

[0064] In some embodiments, the support member 1241 has a rotating part installed corresponding to a predetermined rotation axis part, and a support part 1243 and a connection part 1244 installed on both ends of the rotating part and rotating around the predetermined rotation axis part, the support part 1243 and the connection part 1244 being located on both sides of the predetermined rotation axis part, respectively, and the support part 1243 protrudes from the case body 12 to support the mobile terminal in cooperation with the case cover 11 when the support member 1241 is in a supporting state. The connection part 1244 is connected to the first elastic member 125 and can drive the support member 1241 to rotate.

[0065] In some embodiments, the support member 1241 is rotatably mounted on the case body 12 around a predetermined second rotation axis 127, and a first end of the first elastic member 125 is connected to a connecting portion 1244 of the support member 1241, the connecting portion 1244 being spaced apart from the predetermined rotation axis. A second end of the first elastic member 125 is connected to the case body 12. Preferably, the direction of the elastic force generated by the first elastic member 125 is parallel to the direction of a line connecting the first end and the second end of the first elastic member 125. When the support member 1241 is in the first transitional position, the line connecting the connecting portion 1244 and the second end of the first elastic member 125 and the predetermined rotation axis have an intersection point. In other words, the elastic force direction of the first elastic member 125 is directed toward the predetermined rotation axis. In this case, the elastic force of the first elastic member 125 cannot apply a rotational torque to the support member 1241, and the support member 1241 is in the first transitional position. When the support member 1241 is in the storage position or the support position, the line connecting the connecting portion 1244 and the second end of the first elastic member 125 and the rotation axis are in a twisted position. In this way, the elastic force of the first elastic member 125 can be spatially separated from the predetermined rotation axis. As a result, 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 hold it in the support position or storage position.

[0066] In some embodiments, as shown in FIG. 11 , when the support member 1241 is in the storage 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 torque applied to the support member 1241 causes the support member 1241 to rotate in a first direction. When the support member 1241 is in the support position, as shown in FIG. 13 , the rotation axis is located on the other side of the line connecting the connecting portion 1244 and the second end of the first elastic member 125, and torque applied to the support member 1241 causes the support member 1241 to rotate in a second direction. The first direction is opposite to the second direction and is the direction of rotation from the support position to the storage direction. The second direction is the direction of rotation from the storage position to the support position.

[0067] 11 to 13, when the position of the support member 1241 is between the storage position and the first transitional position, the predetermined rotation axis portion 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 support member 1241 tends to rotate in the first direction due to the torque received by the support member 1241 (see F in FIG. 11). When the support member 1241 is located between the support position and the first transitional position, the rotation axis portion 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 support member 1241 tends to rotate in the second direction due to the torque received by the support member 1241 (see F in FIG. 13).

[0068] In some embodiments, the amount of elastic deformation generated by the first elastic member 125 when the support member 1241 is in the first transitional position is greater than the amount of elastic deformation generated when the support member 1241 is in the supporting position and the retracted position. When the support member 1241 rotates from the first transitional position to the supporting position or the retracted position, the first elastic member 125 elastically drives the support member 1241 to rotate to the corresponding supporting position or the retracted position through elastic recovery. In other words, when the first elastic member 125 is in a compressed state, the amount of compression of the first elastic member 125 is maximized when the support member 1241 is in the first transitional position. This configuration provides a greater elastic force to the first elastic member 125 after the support member 1241 passes through the first transitional position, allowing the support member 1241 to be driven more quickly to rotate to the retracted position or the support position.

[0069] In some embodiments, the first elastic member 125 may be a spring. The following description of the above embodiments will be given using an example in which the first elastic member 125 is a spring. Specifically, the first elastic member 125 is positioned below the second rotating shaft 127 and is adjacent to the left end of the support member 1241 when in the storage position. The support member 1241 can rotate to the storage position when rotated clockwise and to the support position when rotated counterclockwise. In the process of the support member 1241 changing from the storage position to the support position, as shown in FIG. 11 , when the support member 1241 is in the storage position, the elastic force vector generated by the first elastic member 125 against the case cover 11 is located to the left of the second rotating shaft 127 (see F in FIG. 11 ). Due to the torque received by the support member 1241, the support member 1241 tends to rotate clockwise. When the elastic force of the first elastic member 125 prevents the support member 1241 from opening, the user can manually apply a counterclockwise torque to drive the support member 1241 to gradually open to the supporting position by overcoming the torque generated by the first elastic member 125. During the process of gradually opening the support member 1241, the position of the elastic force vector generated by the first elastic member 125 changes with respect to the second rotating shaft portion 127. As shown in FIG. 12 , when the support member 1241 is opened to the first transitional position, the elastic force vector generated by the first elastic member 125 is directed toward the center of the rotating shaft, i.e., the first elastic member 125 does not apply a rotational torque to the support member 1241. 13, as the support member 1241 continues to open, the elastic force vector generated by the first elastic member 125 changes to the right side of the second rotation shaft portion 127 (see F in FIG. 13), and when the support member 1241 is subjected to a counterclockwise torque, the first elastic member 125 can promote the rotation of the support member 1241 to the supporting position by applying a counterclockwise torque to the support member 1241, even without the user applying a counterclockwise torque. In other words, after the support member 1241 passes through the first transitional position, the torque applied by the first elastic member 125 can promote the support member 1241 to automatically rotate to the supporting position.

[0070] 13, when the support member 1241 is in the support position, the elastic force vector generated by the first elastic member 125 on the support member 1241 is located to the right of the second rotation shaft 127 (see F in FIG. 13), and the support member 1241 is subjected to a counterclockwise torque. If the elastic force of the first elastic member 125 prevents the support member 1241 from being folded down, the user can manually apply a clockwise torque to overcome the torque generated by the first elastic member 125, thereby gradually driving the support member 1241 to be folded down. As the support member 1241 is gradually retracted, the position of the elastic force vector generated by the first elastic member 125 changes relative to the second rotating shaft 127. When the support member 1241 is retracted to the first transitional position, as shown in FIG. 12, the elastic force vector generated by the first elastic member 125 is directed toward the center of the rotating shaft, i.e., the first elastic member 125 does not apply torque to the support member 1241. As the support member 1241 continues to retract, as shown in FIG. 11, the elastic force vector generated by the first elastic member 125 changes to the left side of the second rotating shaft 127 (see F in FIG. 11). When the support member 1241 is subjected to a clockwise torque, the first elastic member 125 can apply a clockwise torque to the support member 1241 to promote the rotation of the support member 1241 to the retracted position, even without the user applying a clockwise torque. In other words, after the support member 1241 passes through the first transitional position, the torque applied by the first elastic member 125 can encourage the support member 1241 to automatically retract.

[0071] In some embodiments, the support member 1241 is further provided with a position limiting portion 1242, which abuts against the case body 12 when the support member 1241 is in the support position, thereby restricting further rotation of the support member 1241 and holding the support member 1241 in the support position.

[0072] As shown in FIGS. 14 to 17 , in other embodiments, the first elastic member 125 may be a leaf spring. The following description of the above embodiment will be given using an example in which the first elastic member 125 is a leaf spring. A position limiting section 1242 is provided on the support member 1241, spaced apart from a predetermined rotation axis and configured to rotate around the predetermined rotation axis. The first elastic member 125 includes a fixed section 1252 and an elastic movable section 1251 that is elastically movable relative to the case body 12. The elastic movable section 1251 includes a protrusion 12511 that protrudes toward the position limiting section 1242 and two connection sections 12512 connected to either side of the protrusion 12511. The first elastic member 125 further includes a fixed section 1252 that is connected to one end of the two elastic movable sections 1251 and fixedly connected to the case body 12.

[0073] When the support member 1241 rotates, the position limiting portion 1242 can move between the two connecting portions 12512, passing over the protrusions 12511. When the position limiting portion 1242 passes over the protrusions 12511 from the connecting portions 12512, the elastic movable section 1251 is elastically deformed, and an elastic force generated by the elastic deformation acts on the support member 1241 via the position limiting portion 1242, allowing the support member 1241 to be subjected to a rotational torque. When the support member 1241 is in the first transitional position, the position limiting portion 1242 elastically abuts against the protrusions 12511, and when the support member 1241 is in the storage position or the supporting position, the position limiting portion 1242 elastically abuts against the two connecting portions 12512 correspondingly.

[0074] In some embodiments, the number of elastic movable sections 1251 is two, and the two elastic movable sections 1251 are located at both ends of the support member 1241 and are installed opposite each other; the number of position limiting portions 1242 is two, and the two position limiting portions 1242 extend along the direction of a predetermined rotation axis portion; the two elastic movable sections 1251 abut correspondingly to the two position limiting portions 1242, respectively; by abutting the two elastic movable sections 1251 against the position limiting portions 1242, the force applied by the first elastic member 125 to the support member 1241 can be more evenly distributed to both ends of the support member 1241, thereby reducing the generation of unnecessary rotational torque.

[0075] In some embodiments, the protrusion 12511 is installed to protrude in an arc shape, and the position limiting portion 1242 has an arc-shaped surface that abuts against the elastic movable section 1251. By installing it in this manner, when the position limiting portion 1242 moves from the connecting portion 12512 to the protrusion 12511, the position limiting portion 1242 and the protrusion 12511 can abut continuously, and the direction of the elastic force of the protrusion 12511 against the position limiting portion 1242 can gradually decrease rather than suddenly change, making the rotation process of the support member 1241 smoother.

[0076] As shown in Figures 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 position limiting portion 1242 is located below the protrusion 12511, and is in the support position when the position limiting portion 1242 is located above the protrusion 12511.

[0077] 15 , when the support member 1241 is in the retracted position, the position limiting portion 1242 is located below the protrusion 12511. In this case, when the protrusion 12511 abuts against the lower connecting portion 12512 and the support member 1241 has a tendency to rotate toward the supporting position, the position limiting portion 1242 abuts against the protrusion 12511, and the elastic movable section 1251 is pressed by the position limiting portion 1242 and elastically deforms, thereby generating an elastic force against the position limiting portion 1242. The component of the elastic force in the direction of movement of the position limiting portion 1242 is opposite to the direction of movement of the position limiting portion 1242. The elastic force generates a torque that prevents the rotation of the support member 1241, thereby restricting the rotation of the support member 1241 toward the supporting position. The user manually applies a rotational torque to the support member 1241 to overcome the elastic force of the protrusion 12511 against the position limiting portion 1242, causing the position limiting portion 1242 to gradually move upward past the protrusion 12511, and the support member 1241 to gradually rotate from the storage position to the support position. During the rotation process, the contact position between the position limiting portion 1242 and the protrusion 12511 constantly changes, and because the position limiting portion 1242 and the protrusion 12511 are arranged in an arc, the acting force between them is perpendicular to the tangent of the contact point. The included angle between the direction of the elastic force of the protrusion 12511 against the position limiting portion 1242 and the direction of movement of the position limiting portion 1242 gradually increases, and the elastic direction gradually becomes parallel to the predetermined rotation axis of the support member 1241. During the above process, the component of the elastic force of the protrusion 12511 in the direction of movement of the position limiting portion 1242 also gradually decreases, i.e., the torque preventing the rotation of the support member 1241 gradually decreases. When the direction of the elastic force of the protrusion 12511 relative to the position limiting portion 1242 is perpendicular to the direction of movement of the position limiting portion 1242, the component of the elastic force of the protrusion 12511 in the direction of movement of the position limiting portion 1242 is zero. In this case, the support member 1241 rotates to the first transitional position, and as shown in FIG. 16 , the protrusion 12511 does not restrict the rotation of the support member 1241. As the support member 1241 continues to rotate, the position limiting portion 1242 moves upward, and the contact position between the protrusion 12511 and the position limiting portion 1242 continues to change.After passing the first transitional position, the angle between the direction of elastic force of the protrusion 12511 relative to the position limiting portion 1242 and the direction of movement of the position limiting portion 1242 gradually decreases, and the elastic component in the direction of movement of the position limiting portion 1242 is the same as the direction of movement of the position limiting portion 1242. That is, the elastic force of the protrusion 12511 relative to the position limiting portion 1242 can generate a rotational torque that urges the support member 1241 to rotate to the support position. Even without the user applying torque, the elastic force of the protrusion 12511 pushes the position limiting portion 1242 to move upward, and the support member 1241 can automatically rotate to the support position under the action of the torque of the first elastic member 125 (see FIG. 17).

[0078] 17 , in the process of closing the support member 1241 from the supporting position to the storage position, the support member 1241 is initially in the supporting position. When the support member 1241 is in the supporting position, the position limiting portion 1242 is located above the protrusion 12511. In this case, when the protrusion 12511 abuts against the upper connecting portion 12512 and the support member 1241 has a tendency to rotate toward the storage position, the position limiting portion 1242 abuts against the protrusion 12511, and the elastic movable section 1251 is pushed by the position limiting portion 1242 and elastically deforms, thereby generating an elastic force against the position limiting portion 1242. The component of the elastic force in the direction of movement of the position limiting portion 1242 is opposite to the direction of movement of the position limiting portion 1242. The elastic force generates a torque that prevents rotation of the support member 1241, thereby restricting the rotation of the support member 1241 to the storage position. The user manually applies a rotational torque to the support member 1241 to overcome the elastic force of the protrusion 12511 against the position limiting portion 1242, causing the position limiting portion 1242 to gradually move downward past the protrusion 12511, and the support member 1241 to gradually rotate from the supporting position to the storage position. During the rotation process, the contact position between the position limiting portion 1242 and the protrusion 12511 constantly changes, and because the position limiting portion 1242 and the protrusion 12511 are arranged in an arc, the acting force between them is perpendicular to the tangent of the contact point. The included angle between the direction of the elastic force of the protrusion 12511 against the position limiting portion 1242 and the direction of movement of the position limiting portion 1242 gradually increases, and the elastic direction gradually becomes parallel to the predetermined rotation axis of the support member 1241. During the above process, the component of the elastic force of the protrusion 12511 in the direction of movement of the position limiting portion 1242 also gradually decreases, i.e., the torque preventing the rotation of the support member 1241 gradually decreases. When the direction of the elastic force of the protrusion 12511 relative to the position limiting portion 1242 is perpendicular to the direction of movement of the position limiting portion 1242, the component of the elastic force of the protrusion 12511 in the direction of movement of the position limiting portion 1242 is zero. In this case, the support member 1241 rotates to the first transitional position, and as shown in FIG. 16 , the protrusion 12511 does not restrict the rotation of the support member 1241. As the support member 1241 continues to rotate, the position limiting portion 1242 moves downward, and the contact position between the protrusion 12511 and the position limiting portion 1242 continues to change.After passing the first transitional position, the angle between the direction of elastic force of the protrusion 12511 relative to the position limiting portion 1242 and the direction of movement of the position limiting portion 1242 gradually decreases, and the elastic component in the direction of movement of the position limiting portion 1242 is the same as the direction of movement of the position limiting portion 1242. That is, the elastic force of the protrusion 12511 relative to the position limiting portion 1242 can generate a rotational torque that urges the support member 1241 to rotate to the storage position. Even without the user applying torque, the elastic force of the protrusion 12511 pushes the position 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 (see FIG. 15 ).
