Description

Technical Field

[0001] The present application relates to the technical field of digital products, and in particular to a charging box. Background Art

[0002] With the market demand for portable products, wireless earphones have gradually become the first choice for consumers due to their small size, light weight, and elimination of the entanglement problem of wired earphones. Wireless earphones generally communicate with terminals through wireless communication technology, which can not only meet consumers' daily needs for listening to music and making calls, but can also be used as independent terminals.

[0003] In order to improve the battery life of wireless earphones, they are usually carried and charged in a charging box. When the earphones are not in use, they are stored in the charging box and taken out of the charging box when they are used. When the cover of the charging box is opened and closed, a large impact force will be generated on the box body, and this impact force may damage the electronic components in the charging box, thereby affecting the performance of the charging box. Summary of the invention

[0004] The present application aims to solve one of the technical problems existing in the prior art or related technology.

[0005] The present application aims to provide a charging box and a wireless earphone kit, which at least solves the problem that the cover has no buffer when opening and closing the cover, resulting in a large impact force and causing damage to the body of the charging box.

[0006] In the first aspect, the embodiment of the present application proposes a charging box, including: a box body, a cover body, a rotating member, a moving assembly and a buffer assembly. The cover body is connected to the box body; the rotating member is arranged on the cover body, and the cover body is rotatably connected to the box body through the rotating member; the moving assembly is arranged on the box body, and during the rotation of the cover body relative to the box body, the rotating member rotates and drives the moving assembly to move between a first position and a second position; the buffer assembly is arranged on the box body, and the buffer assembly can provide a buffering force to the moving assembly during the movement of the moving assembly between the first position and the second position.

[0007] In a second aspect, an embodiment of the present application proposes a wireless earphone kit, which includes: a charging box and earphones as in the first aspect, wherein the charging box is used to accommodate the earphones and provide power to the earphones.

[0008] In an embodiment of the present application, the charging box includes a box body and a cover body, wherein the box body is used to place the earphones. The cover body is movably disposed at the open end of the box body, and the opening of the box body can be opened or closed by moving the cover body to different positions. Furthermore, a rotating member is provided between the cover body and the box body, and the cover body is connected to the box body through the rotating member. On the one hand, the rotating member limits the cover body to prevent the cover body from falling off the box body, and on the other hand, the cover body can also be rotated relative to the box body through the rotating member. When the cover body is rotated to a specific angle, it can be buckled on the box body, and when a force is applied to the buckled cover body in a direction away from the box body, the cover body can also be rotated to open the box body.

[0009] When the cover is buckled onto the box body, it is easy to generate impact on the box body if the cover is not buffered. In order to solve this problem, a motion component and a buffer component are also provided in the charging box.

[0010] The moving assembly is arranged on the box body and connected to the rotating member, and the moving assembly can move between different positions with the rotation of the rotating member. Specifically, during the process of the cover body being separated from or fastened to the box body, the cover body rotates relative to the box body, and at the same time, the cover body drives the rotating member to rotate synchronously relative to the box body. During the rotation process, the rotating member drives the moving assembly to move. When the cover body rotates to the position of fastening with the box body, the moving member moves to the first position, and when the cover body rotates to the extreme position of being separated from the shell, the moving member moves to the second position.

[0011] Furthermore, a buffer assembly is also provided on the box body, and the buffer assembly cooperates with the moving assembly to play a buffering role on the cover body. Specifically, when the moving member moves between the first position and the second position, the buffer assembly applies a buffering force to the moving member to reduce the rotation speed of the rotating member, thereby reducing the rotation speed of the cover body synchronously, and then the cover body is engaged with the box body at a lower rotation speed, reducing the impact on the box body; or, the cover body is separated from the box body at a lower rotation speed, preventing the cover body from stopping rotation immediately without buffering, thereby reducing damage to the cover body and the box body.

[0012] By setting a motion component and a buffer component in the charging box, a certain buffer can be generated when the cover is separated or buckled relative to the box body, reducing the impact on the box body, protecting the charging box, and reducing the noise generated when the cover is buckled on the box body.

[0013] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0039] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0040] In the related art, the charging box includes a box body and a cover body, and the cover body can be buckled on the box body. However, the existing charging box has the following problems. First, the cover body of the charging box is relatively loose when the cover is opened or closed. Second, the impact force of the cover body is large when the cover is opened or closed, which can easily cause damage to the box body and generate a lot of noise.

[0041] The charging box provided in the embodiment of the present application can reduce the impact force of opening and closing through the buffer component when the lid is open or closed, thereby protecting the box body, and by providing an elastic member between the cover body and the box body, the cover body will not shake under the action of the elastic member regardless of whether the lid is open or closed.

[0042] The charging box 100 provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0043] like Figures 1 to 6 , Fig.11 and Fig.12 As shown, the charging box 100 includes: a box body 110, a cover body 120, a rotating member 130, a moving assembly 140 and a buffer assembly 150. The cover body 120 is arranged on the box body 110; the rotating member 130 is arranged on the cover body 120, and the cover body 120 can rotate relative to the box body 110 through the rotating member 130; the moving assembly 140 is arranged on the box body 110, and when the cover body 120 is separated or fastened relative to the box body 110, the rotating member 130 rotates and drives the moving assembly 140 to move between the first position and the second position; the buffer assembly 150 is arranged on the box body 110, and the buffer assembly 150 can provide a buffer force to the moving assembly 140 when the moving assembly 140 moves between the first position and the second position.

[0044] Specifically, the charging box 100 provided in the present application includes a box body 110 and a cover body 120, wherein the box body 110 is used to place the earphone. The cover body 120 is movably arranged at the open end of the box body 110, and the opening of the box body 110 can be opened or closed by moving the cover body 120 to different positions. Further, a rotating member 130 is provided between the cover body 120 and the box body 110, and the cover body 120 is connected to the box body 110 through the rotating member 130. On the one hand, the rotating member 130 limits the cover body 120 to prevent the cover body 120 from falling off the box body 110, and on the other hand, the cover body 120 can also be rotated relative to the box body 110 through the rotating member 130. When the cover body 120 is rotated to a specific angle, it can be buckled on the box body 110, and when a force is applied to the buckled cover body 120 in a direction away from the box body 110, the cover body 120 can also be rotated to open the box body 110.

[0045] When the cover 120 is buckled onto the box body 110 , it is easy to generate an impact on the box body 110 if the cover 120 is not buffered. In order to solve this problem, a motion component 140 and a buffer component 150 are further provided in the charging box 100 .

[0046] The motion assembly 140 is disposed on the box body 110 and connected to the rotating member 130. The motion assembly 140 can move between different positions as the rotating member 130 rotates. Specifically, during the process of the cover body 120 being separated or fastened relative to the box body 110, the cover body 120 rotates relative to the box body 110, and at the same time, the cover body 120 drives the rotating member 130 to rotate synchronously relative to the box body 110. During the rotation process, the rotating member 130 drives the motion assembly 140 to move. When the cover body 120 rotates to the position of fastening with the box body 110, the motion assembly 140 moves to the first position. When the cover body 120 rotates to the extreme position of being separated from the shell, the motion assembly 140 moves to the second position.

[0047] Furthermore, the buffer assembly 150 is also disposed on the box body 110, and the buffer assembly 150 cooperates with the motion assembly 140 to play a buffering role on the cover body 120. Specifically, when the motion assembly 140 moves between the first position and the second position, the buffer assembly 150 applies a buffering force to the motion assembly 140 to reduce the rotation speed of the rotating member 130, so that the rotation speed of the cover body 120 is synchronously reduced, and then the cover body 120 is buckled or engaged with the box body 110 at a lower rotation speed, reducing the impact on the box body 110; or, the cover body 120 is separated from the box body 110 at a lower rotation, preventing the cover body 120 from stopping rotation immediately without buffering, reducing damage to the cover body 120 and the box body 110, and will not affect the user's normal opening or closing of the cover body 120.

[0048] By providing a motion component 140 and a buffer component 150 in the charging box 100, a certain buffer can be generated when the cover body 120 is separated or buckled relative to the box body 110, thereby reducing the impact on the box body 110, protecting the charging box 100, and reducing the noise generated when the cover body 120 is buckled on the box body 110.

[0049] Furthermore, in the process that the moving component 140 moves from the first position to the second position, and in the process that the moving component 140 moves from the second position to the first position, the buffering force of the buffering component 150 on the moving component 140 gradually increases.

[0050] Specifically, the buffer force generated by the buffer assembly 150 on the moving assembly 140 changes with the change of the position of the moving assembly 140. When the moving assembly 140 moves toward the first position, the smaller the distance between the moving assembly 140 and the first position, the greater the buffer force generated by the buffer assembly 150 on the moving assembly 140, that is, in the process of the cover body 120 buckling, the closer the cover body 120 is to the position of buckling with the box body 110, the greater the rotation resistance of the cover body 120. Therefore, on the one hand, the cover body 120 can rotate at a faster speed when it is just buckled, which does not affect the user's hand feeling when closing the cover, and on the other hand, when it is close to the position of buckling with the box body 110, that is, in the last short stroke before the moving assembly 140 reaches the first position, under the action of the buffer force generated by the buffer assembly 150, the movement resistance of the moving assembly 140 is enhanced, and the rotation speed of the cover body 120 is reduced, so that the cover body 120 can be buckled with the box body 110 at a slower speed to avoid generating an impact on the box body 110.

[0051] Furthermore, when the moving assembly 140 moves toward the second position, the smaller the distance between the moving assembly 140 and the second position, the greater the resistance generated by the buffer assembly 150 to the moving assembly 140, that is, in the process of opening the cover 120, the closer the cover 120 is to the limit position separated from the box body 110, the greater the rotation resistance of the cover 120. Thus, on the one hand, the cover 120 can rotate at a faster speed when it is just opened, which does not affect the user's hand feeling when opening the cover, and on the other hand, when it is close to the limit position separated from the box body 110, under the action of the increased buffer force, the movement resistance of the moving assembly 140 is enhanced, and the rotation speed of the cover 120 is reduced, so that the cover 120 can be rotated to the limit position at a slower speed, avoiding the cover 120 from being damaged by impact.

[0052] It should be noted that, in the process of the moving component 140 moving from the first position to the second position, and in the process of the moving component 140 moving from the second position to the first position, the buffering force exerted by the above-mentioned buffering component 150 on the moving component 140 gradually increases, but the directions of the buffering force generated in the above-mentioned two processes are different.

[0053] It can be understood that the buffer component 150 can generate a buffer force by generating deformation. The greater the deformation generated by the buffer component 150, the greater the buffer force generated by the buffer component 150 on the moving component.

[0054] By setting the buffering force applied by the buffering component 150 to the moving component 140 to a gradually increasing variable force, on the one hand, when the cover body 120 is just beginning to be opened or just beginning to be fastened, the cover body 120 can be subjected to a smaller buffering force, so that it can be rotated at a faster speed, shortening the fastening or opening time; on the other hand, before the cover body 120 is closed on the box body 110 or before the cover body 120 is in the extreme position of opening the cover, the increased buffering force can reduce the rotation speed of the cover body 120, so that the cover body 120 approaches or separates from the box body 110 at a slower speed, avoiding impact on the cover body 120 and the box body 110, and reducing the noise generated when the cover body 120 is fastened.

[0055] like Figures 4 to 7 as well as Fig.16 As shown, further, the above-mentioned box body 110 also includes: a box bracket 112, the bracket 112 includes two mounting ears 113 extending along the height direction of the box body 110, and the mounting ears 113 are provided with a through hole 114, and the through hole 114 is used to accommodate at least part of the rotating member 130; the cover body 120 includes: a mounting member 122, which is arranged at the open end of the cover body 120; and a mounting groove 123, which is through-arranged in the mounting member 122, and the mounting groove 123 is used to accommodate the rotating member 130, and the rotating member 130 extends out of the mounting groove 123 and is placed in the through hole 114.

[0056] In order to enable the box body 110 and the cover body 120 to be rotatably connected via the rotating member 130 , mutually matching connecting structures are further provided on the cover body 120 and the box body 110 .

[0057] Specifically, the charging box 100 also includes a bracket 112, and the bracket 112 includes two mounting ears 113. The two mounting ears 113 are respectively arranged on both sides of the bracket 112 and extend along the height direction of the box body 110. A through hole 114 is provided on the two mounting ears 113, wherein the two through holes 114 are coaxially arranged.

[0058] Furthermore, the charging box 100 also includes a mounting member 122 , which is disposed at the open end of the cover body 120 . Specifically, the mounting member 122 is disposed on the outer shell on one side of the open end, and a mounting groove 123 is also provided on the mounting member 122 , and the mounting groove 123 passes through the mounting member 122 .

[0059] Furthermore, the mounting member 122 can be installed between the two mounting ears 113, so that the mounting groove 123 on the mounting member 122 and the through hole 114 on the mounting ear 113 are connected to each other, and the rotating member 130 can be inserted into the mounting groove 123 and at least partially disposed in the through hole 114, so that the cover body 120 and the box body 110 are connected together through the rotating member 130.

[0060] The inner diameter of the through hole 114 is larger than the cross-sectional dimension of the rotating member 130, and the rotating member 130 can rotate freely in the through hole 114. The inner cavity dimension of the mounting groove 123 is the same as the cross-sectional dimension of the rotating member 130 or slightly smaller than the cross-sectional dimension of the rotating member 130, so that the rotating member 130 and the mounting groove 123 are in an interference fit state, and the rotating member 130 is driven to rotate during the rotation of the shell. The inner cavity dimension of the mounting groove 123 can also be larger than the cross-sectional dimension of the rotating member 130. In this case, the rotating member 130 and the cover body 120 can be relatively fixed by welding or bonding the rotating member 130 to the mounting groove 123, or the rotating member 130 and the cover body 120 can be fixed in other ways.

[0061] By providing a mounting groove 123 on the cover body 120 and a through hole 114 on the box body 110 adapted to the mounting groove 123 , the moving member 141 is inserted into the mounting groove 123 and the through hole 114 , so as to realize the rotation connection between the cover body 120 and the box body 110 .

[0062] like Figures 4 to 7 as well as Fig.18 As shown, further, the box body 110 also includes: a box body inner cover 115, which is arranged in the box body 110, and a avoidance opening 116 is arranged on the box body inner cover 115, and the avoidance opening 116 is used to accommodate the bracket 112; the box body inner cover 115 is provided with a first mounting hole 117, and the first mounting hole 117 is arranged corresponding to the rotating member 130 on the bracket.

[0063] Specifically, the box body 110 is further provided with a box body inner cover 115, which is provided at the open end of the box body 110 and is located inside the box body 110. The box body inner cover 115 is provided with an earphone receiving groove for receiving earphones, and the earphones can be placed in the earphone receiving groove to fix the earphones. The box body inner cover 115 is also provided with an avoidance opening 116, which is provided on a side facing the inner cavity of the box body 110, and the bracket 112 is provided in the avoidance opening.

[0064] Furthermore, a pair of first mounting holes 117 are provided on the box body cover 115, respectively located on both sides of the bracket. The first mounting holes 117 are correspondingly arranged with the through holes 114 on the mounting ears 113 on the bracket, so that the axis of the first mounting hole 117 can be consistent with the axis of the rotating member 130.

[0065] like Figures 5 to 7 as well as Figure 12 to Figure 14 As shown, further, the box body 110 also includes: the moving component 140 includes: two moving parts 141, the two moving parts 141 are respectively movably arranged on the box body inner cover 115, and are located at both ends of the rotating part 130, and the first end of any one of the two moving parts 141 extends into the rotating part 130; and the rotating part 130 drives the moving part 141 to rotate, and during the operation, the moving component 140 can move to the first position or the second position along the extension direction of the rotating part 130.

[0066] Specifically, the moving assembly 140 includes two moving members 141, which are respectively disposed at two ends of the rotating member 130, and the two moving members 141 are respectively movably connected to the two ends of the rotating member 130. Specifically, the first end of the moving member 141 extends into the rotating member 130, and the moving member 141 and the rotating member 130 are mutually limited along the rotation direction of the rotating member 130, so that the moving member 141 can rotate with the rotating member 130.

[0067] It can be understood that the rotating member 130 limits the moving member 141 along the rotation direction of the rotating member 130, while the rotating member 130 does not limit the moving member 141 along the extension direction of the rotating member 130. During the rotation of the rotating member 130, the moving member 141 rotates synchronously with the rotating member 130. Since the rotating member 130 does not limit the moving member 141 along the extension direction of the rotating member 130, the moving member 141 can move to the first position or the second position along the extension direction of the rotating member 130 during the rotation of the rotating member 130. By inserting the first end of the moving member 141 into the rotating member 130, the moving member 141 rotates with the rotating member 130, and the moving member 141 moves to the first position or the second position along the extension direction of the rotating member 130 while rotating, the process of converting the rotation into the linear movement is realized, and the buffering effect of the buffer assembly 150 is realized during the opening and closing of the cover body 120.

[0068] Specifically, if Figure 12 to Figure 14 As shown, when the cover body 120 and the box body 110 are buckled together, the two moving parts 141 move to the first position; Figures 5 to 7 As shown, in a state where the cover body 120 is separated from the box body 110 , the two moving members 141 move to the second position.

[0069] Furthermore, if Figure 12 to Figure 14As shown, during the process of the cover 120 opening and closing relative to the box body 110, the moving component 140 moves along the first direction with the rotating member 130 and starts to move with the first position as the target position. When the moving component 140 moves, the buffering component 150 applies a buffering force to the moving component. During the closing process of the cover 120, the closer the cover 120 is to the position of closing with the box body 110, the greater the buffering force generated by the buffering component 150 on the moving member 141. In particular, in the last short stroke of the moving member 141 before reaching the first position, the increased buffering force is sufficient to reduce the movement speed of the moving member 141, thereby reducing the rotation speed of the rotating member 130, so that the cover 120 reduces the impact force on the box body 110. Figures 5 to 7 As shown, in the process of the cover body 120 moving from the snap-fit ​​position to the open position relative to the box body 110, the moving component 140 moves along the second direction with the rotating member 130 and starts to move with the second position as the target position. When the moving component 140 moves, the buffer component 150 applies a buffering force to the moving component 140. In the process of opening the cover body 120, the closer the cover body 120 is to the extreme opening position of the box body 110, the greater the buffering force generated by the buffer component 150 on the moving member 141. In particular, in the last short stroke of the moving member 141 before reaching the second position, the increased buffering force is sufficient to alleviate the movement speed of the other moving member 141, thereby alleviating the rotation speed of the rotating member 130, so that the cover body 120 reduces the impact force on the box body 110.

[0070] It can be understood that the first direction and the second direction are two opposite directions along the extension direction of the rotating member.

[0071] like Fig.17 , Fig.19 and Fig. 20 As shown, further, a second mounting hole 131 is provided on the end face of the rotating member 130, the cross section of the second mounting hole 131 is a first polygon, and the cross section of the part of the moving member 141 extending into the second mounting hole 131 is a second polygon adapted to the first polygon.

[0072] It is understandable that polygons have edges. When two objects with polygonal cross-sections are nested together, when one of the objects is rotating, the two objects can be mutually limited by the position of the edges of the polygon, so that one object drives the other object to rotate. Specifically, the end face of the rotating member 130 in the present application is provided with a second mounting hole 131, and the cross-section of the second mounting hole 131 is a first multiple deformation. Accordingly, the cross-section of the portion of the moving member 141 extending into the second mounting hole 131 is set to a second multiple deformation that is compatible with the first polygon, that is, the contour shape of the first polygon is similar to that of the second polygon, so that when the rotating member 130 is rotating, the mutual limiting function of the two polygons is used to achieve the technical effect that the rotating member 130 drives the two moving members 141 to rotate synchronously.

[0073] Furthermore, the first polygon is larger than the second polygon, that is, there is a gap between the moving member 141 and the rotating member 130 , so that the moving member 141 can freely move in the second mounting hole 131 along the extending direction of the rotating member 130 to the first position or the second position.

[0074] By setting the cross-section of the second mounting hole 131 to a first polygon and the cross-section of the portion of the moving part 141 extending into the second mounting hole 131 to a matching second polygon, it is possible to achieve both the rotational part 130 driving the moving part 141 to rotate therewith and the movement of the moving part 141 in the second mounting hole 131 along the extension direction of the rotational part 130.

[0075] like Figure 6 and Fig.13 As shown, further, the depth of the second mounting hole 131 is greater than the length of the moving member 141 that can be extended into the second mounting hole 131.

[0076] It is understandable that setting the depth of the second mounting hole 131 to be greater than the length by which the moving member 141 can extend into the second mounting hole 131 can reserve sufficient movement space for the moving member 141 when the moving member 141 moves in different directions, so that the moving member 141 can move normally.

[0077] Furthermore, the depth of the second mounting hole 131 is set to be greater than the length of the moving part 141 that can be extended into the second mounting hole 131, so that the part of the moving part 141 that cooperates with the rotating part 130 can be fully extended into the second mounting hole 131, thereby maximizing the matching size of the rotating part 130 and the moving part 141, reducing the force per unit area of ​​the moving part 141, and extending the service life of the moving part 141.

[0078] Furthermore, by setting the depth of the second mounting hole 131 to be greater than the length that the moving part 141 can extend into the second mounting hole 131, the moving part 141 can be prevented from contacting the bottom wall of the second mounting hole 131, and friction can be prevented from being generated between the moving part 141 and the bottom wall of the second mounting hole 131, thereby improving the movement stability of the moving part 141 and preventing other external forces from affecting the movement of the moving part 141.

[0079] like Figure 6 , Fig.13 , Fig.14 , Figures 18 to 20 As shown, further, the box body 110 also includes: a first mounting hole 117, which is arranged on the box body inner cover 115, and the second end of the moving part 141 is inserted into the first mounting hole 117, and a first thread is arranged in the first mounting hole 117; the part of the moving part 141 placed in the first mounting hole 117 is provided with a second thread 142 adapted to the first thread, and when the rotating part 130 drives the moving part 141 to rotate, the second thread 142 cooperates with the first thread to move the rotating part 130 to the first position or the second position.

[0080] In order to enable the moving member 141 to move along the extension direction of the rotating member 130 while rotating, the present application provides mutually matching guiding structures on the moving member 141 and the box body inner cover 115. Specifically, a first mounting hole 117 is provided on the box body inner cover 115, the first mounting hole 117 is a through hole 114, and the axial direction of the first mounting hole 117 is the same as the extension direction of the rotating member 130, and the second end of the moving member 141 is inserted into the first mounting hole 117. A first thread is provided on the inner wall of the first mounting hole 117, and a second thread 142 is provided at the portion of the moving member 141 located in the first mounting hole 117, and the first thread matches the second thread 142.

[0081] As the moving part 141 moves with the rotation of the rotating part 130, the first thread and the second thread 142 engage with each other. As the moving part 141 rotates, the second thread 142 rotates along the first thread, thereby driving the moving part 141 to move along the axial direction of the first mounting hole 117, that is, along the extension direction of the rotating part 130. When the cover body 120 rotates to the extreme position, the moving part 141 moves to the first position or the second position.

[0082] By setting a first thread in the first mounting hole 117 and setting a second thread 142 that is adapted to the first thread on the moving part 141, the moving part 141 can be driven to move to the first position or the second position along the extension direction of the rotating part 130 during rotation by the second thread 142 rotating relative to the first thread.

[0083] Optionally, the moving part can also move to the first position or the second position through a magnetic attraction structure. Specifically, a first electromagnetic part is provided on the moving part, and a second electromagnetic part is provided in the first mounting hole. The first electromagnetic part and the second electromagnetic part generate magnetism when powered on and attract each other. In the process of opening the cover body, the first electromagnetic part and the second electromagnetic part close to the first position side are powered on, and the first electromagnetic part and the second electromagnetic part close to the second position side are powered off. The second electromagnetic part close to the first position side attracts the corresponding first electromagnetic part, so that the first electromagnetic part drives the moving part to move in the first mounting hole in the direction of the first position. In the process of closing the cover body, the first electromagnetic part and the second electromagnetic part close to the second position side are powered on, and the first electromagnetic part and the second electromagnetic part close to the first position side are powered off. The second electromagnetic part close to the second position side attracts the corresponding first electromagnetic part, so that the first electromagnetic part drives the moving part to move in the first mounting hole in the direction of the second position.

[0084] Furthermore, a central axis of the first mounting hole 117 is colinear with a central axis of the moving member 141 .

[0085] Understandably, the moving member 141 drives the second thread 142 to rotate relative to the first thread, thereby driving the moving member 141 to move in the first mounting hole 117 through the screwing of the second thread 142. If the moving member 141 and the first mounting hole 117 are not coaxially arranged, then in the process of the moving member 141 driving the second thread 142 to rotate relative to the first thread, the second thread 142 rotates eccentrically relative to the first thread, which will cause uneven force on various positions of the first thread and the second thread 142, which will not only cause the movement state of the moving member 141 to be unstable, but also cause the positions of the first thread and the second thread 142 that are subjected to greater force to be easily damaged, thereby shortening the service life of the moving member 141 and the rotating member 130. In order to avoid the occurrence of this phenomenon, the present application sets the central axis of the first mounting hole 117 and the central axis of the moving member 141 to be colinear, so that the forces on various positions of the first thread and the second thread 142 are balanced, thereby improving the stability of the movement of the moving member 141 and extending the service life of the moving member 141 and the rotating member 130.

[0086] like Figure 6 , Fig.13 , Fig.14 , Fig.18 , Fig.21 and Fig. 22As shown, further, the box body 110 also includes: a mounting column 118, which is constructed as a cavity structure with openings at both ends, the mounting column 118 is arranged on the box body inner cover 115 away from the bracket 112, and the second end of the moving part 141 can be inserted into the mounting column 118 and can move in the mounting column 118; the buffer assembly 150 includes: two deformable parts 151, which are arranged at the first end of the mounting column 118, and the deformable parts 151 are deformed when the moving part 141 moves between the first position and the second position to apply buffering force to the moving part 141.

[0087] Specifically, a mounting post 118 is respectively provided on both sides of the box body cover 115 away from the bracket 112. The mounting post 118 is a cavity structure with two ends open. The first mounting hole 117 on the box body cover 115 is connected to the cavity in the mounting post 118. The second end of the moving member 141 can extend into the mounting post 118 through the first mounting hole 117. As the moving member 141 moves in the first mounting hole 117 under the guidance of the first thread and the second thread 142, the second end of the moving member 141 moves relative to the mounting post 118 along the extension direction of the rotating member 130.

[0088] Further, the buffer assembly 150 includes two deformable members 151, and the two deformable members 151 are respectively arranged at the first ends of the two mounting posts 118. Specifically, one end of the deformable member 151 is provided with an opening, and the other end is closed, and one side of the opening is sleeved on the first end of the mounting post 118 to block the opening of the mounting post 118, and the second end of the mounting post 118 is arranged on the box body inner cover 115, and the cavity of the mounting post 118 is connected to the first mounting hole 117. Since the moving member 141 can move in the mounting post 118, the deformable member 151 blocks the opening of the mounting post 118, and therefore, as the moving member 141 moves, the air pressure in the deformable member 151 will change. In order to avoid a gap between the deformable member 151 and the mounting column 118, the deformable member 151 and the mounting column 118 can be bonded by an adhesive, thereby eliminating the gap between the deformable member 151 and the mounting column 118. When the moving member 141 extends into the mounting column 118, the moving member 141 blocks the opening side of the deformable member 151, so that a relatively closed space is formed inside the deformable member 151. Furthermore, the deformable member 151 has a certain elasticity, and the deformable member 151 can expand or contract slightly with the change of the internal air pressure.

[0089] Furthermore, the deformable member 151 may be made of a deformable material, such as silicone.

[0090] like Figure 12 to Figure 14As shown, during the closing process of the cover body 120, the two moving parts 141 move simultaneously. When the moving part 141 located on the right side of the two moving parts 141 moves toward the first position, as the moving part 141 moves, the space inside the deformable part 151 corresponding to the moving part 141 is compressed. At this time, the air pressure inside the deformable part 151 increases, and the increased air pressure acts on the moving part 141, generating a buffering force on the moving part 141. In the initial stage of closing the cover, the above-mentioned buffering force is small and does not affect the user's hand feeling when closing the cover. When the cover body 120 moves to the last short stroke before the closing position, that is, the last stroke before the moving part 141 moves to the first position, the buffering effect of the deformable part 151 corresponding to the moving part 141 on the moving part 141 becomes more obvious, slowing down the moving speed of the moving part 141, thereby playing a buffering role. The increased air pressure also acts on the body of the deformable member 151, thereby causing the deformable member 151 to expand slightly, so as to prevent the air pressure in the deformable member 151 from being too high and causing the moving member 141 to be unable to continue to move to the first position. Figures 5 to 7 As shown, during the process of opening the cover 120, the two moving parts 141 move simultaneously. When the other moving part 141 located on the left side of the two moving parts 141 moves toward the second position, similar to the process of closing the cover 120, in the initial stage of opening the cover, the buffering force generated by the deformable part 151 on the moving part 141 is small and does not affect the hand feeling of the user when opening the cover. When the cover 120 moves to the last short section before the cover opening position, that is, in the last section before the moving part 141 moves to the second position, the buffering effect of the deformable part 151 corresponding to the moving part 141 on the moving part 141 becomes more obvious, thereby buffering the rotation speed of the rotating part 130, and further reducing the impact force of the cover 120 on the box body 110. By arranging the deformable part 151 on the mounting column 118, the space in the deformable part 151 is reduced as the moving part 141 moves, and the buffering force is applied to the moving part 141 by the increase of air pressure, so as to achieve the buffering effect on the cover 120. Deformable members 151 are respectively arranged on the mounting posts 118 on both sides of the inner cover 115 of the box body, so as to achieve a buffering effect during the process of opening and closing the cover body 120.

[0091] It should be noted that if Figure 12 to Figure 14 As shown, during the closing process of the cover body 120, one of the two moving parts 141 located on the left side simultaneously moves to the right side, and its corresponding deformable part 151 may shrink slightly; similarly, Figures 5 to 7As shown, during the closing process of the cover body 120, one of the two moving parts 141 located on the right side simultaneously moves to the left side, and its corresponding deformable part 151 may also shrink slightly. However, since the first mounting holes 117 of the moving parts 141 are connected by threads, that is, the moving position of the moving parts 141 moving with the rotating part 130 has been fixed by threads, the slight shrinkage of the deformable part 151 will not have a substantial impact on the movement of the moving parts 141. Furthermore, the central axis of the mounting column 118 is colinear with the central axis of the moving part 141.

[0092] Understandably, the moving part 141 moves in the mounting column 118, squeezing the space in the deformation part 151 to generate a relatively increased air pressure, which plays a buffering role. There is only a small gap between the inner wall surface of the mounting column 118 and the moving part 141, otherwise the moving part 141 cannot block the deformation part 151, which will cause the deformation part 151 to leak. In the case where the gap between the mounting column 118 and the moving part 141 is small, if the mounting column 118 and the moving part 141 are not coaxially arranged, then during the movement of the moving part 141 in the mounting column 118, it is easy to interfere with the mounting column 118 due to the deviation of the movement trajectory, or cause the gaps on both sides of the moving part 141 and the mounting column 118 to be different in size, resulting in air leakage of the deformation part 151. In order to avoid the above problems, the present application sets the central axis of the mounting column 118 and the central axis of the moving part 141 to be colinear, so that the moving part 141 can move smoothly in the mounting column 118, so that the gap between the mounting column 118 and each position of the moving part 141 remains balanced, and the deformation part 151 is prevented from leaking.

[0093] like Figure 3 , Fig.10 , Fig.15 and Fig.16 As shown, the charging box 100 also includes: a first support member 119, which is arranged on the bracket 112, and there is a first angle between the extension direction of the first support member 119 and the base of the bracket 112; a second support member 124, which is arranged on the side of the mounting member 122 facing the box body 110; an elastic member 160, and the first end of the elastic member 160 is sleeved on the first support member 119, and the second end of the elastic member 160 is sleeved on the second support member 124.

[0094] The charging box 100 is also provided with an elastic member 160, which is arranged between the box body 110 and the cover body 120. During the opening and closing process of the cover body 120, the elastic member 160 applies forces in different directions to the cover body 120 so that the cover body 120 can be opened and closed smoothly and remain stable. Specifically, a first support member 119 is provided on the bracket 112, and there is a certain angle between the extension direction of the first support member 119 and the base of the bracket 112. Preferably, the extension direction of the first support member 119 is toward the side of the mounting member 122 on the cover body 120. A second support member 124 is also provided on the mounting member 122, and the second support member 124 is arranged on the side facing the box body 110. Among them, the first support member 119 and the second support member 124 are both cylinders.

[0095] Furthermore, an elastic member 160 is provided between the bracket 112 and the cover body 120, and the first end of the elastic member 160 is sleeved on the first support member 119, and the second end of the elastic member 160 is sleeved on the second support member 124, thereby fixing the elastic member 160 between the bracket 112 and the cover body 120 to prevent the elastic member 160 from falling off from the charging box 100.

[0096] The elastic member 160 is always in a compressed state, so that the elastic member 160 can exert a corresponding force on the cover body 120 during the process of opening and closing the cover body 120 .

[0097] like Figures 8 to 10 As shown, specifically, during the process of opening the cover 120, the elastic member 160 applies a force to the mounting member 122 along the extension direction of the second support member 124 toward the cover 120. Since the mounting member 122 is arranged on the cover 120, the cover 120 is pushed to rotate relative to the box body 110, and the cover 120 is opened. When the cover 120 is opened to the limit position, the elastic member 160 continues to apply a force to the cover 120 along the extension direction of the second support member 124, so that the cover 120 still maintains a tendency to continue to rotate. At this time, the cover 120 is pushed by the elastic member 160 on the one hand, and there is a tendency to continue to rotate in the opening direction. On the other hand, when the cover 120 rotates to a specific angle, the box body 110 contacts the cover 120, which plays a limiting role on the cover 120, preventing the cover 120 from continuing to rotate, so that the cover 120 can not only maintain the open state, but also avoid loosening under the thrust of the elastic member 160.

[0098] During the closing process of the cover 120 , the user needs to apply a certain force to the cover 120 to overcome the thrust of the elastic member 160 . Under the action of both the external force applied by the user and the reverse thrust of the elastic member 160 , the cover 120 can rotate smoothly until it is buckled onto the box body 110 .

[0099] By arranging an elastic member 160 between the cover body 120 and the box body 110, the elastic member 160 applies a thrust to the cover body 120, so that the cover body 120 can maintain stable rotation during the opening and closing processes, and when the cover body 120 is opened to the extreme position, the elastic member 160 continues to apply a thrust to the cover body 120, so that the cover body 120 and the box body 110 can remain relatively stable and prevent the cover body 120 from loosening.

[0100] like Fig.15 As shown, further, the charging box 100 also includes: a support member 125, which is arranged on the side of the mounting member 122 facing the box body 110 and extends in the direction away from the cover body 120; when the cover body 120 is in the open position, the elastic member 160 abuts against the free end of the support member 125, and when the cover body 120 is in the closed position, the elastic member 160 abuts against the side wall of the support member 125.

[0101] Specifically, the mounting member 122 is further provided with a support member 125, which faces one side of the box body 110 and extends in a direction away from the cover body 120. When the cover body 120 is in different positions, the elastic member 160 abuts against different positions of the support member 125. When the cover body 120 is in the open position, the elastic member 160 abuts against the free end of the support member 125, and the elastic member 160 applies a force to the support member 125 that makes the cover body 120 rotate in the opening direction, so that the cover body 120 is firmly maintained in the open limit position. When the cover body 120 is in the closed position, the elastic member 160 abuts against the side wall of the support member 125, and the elastic member 160 applies a force to the support member 125 that makes the cover body 120 rotate in the closing direction, so that the cover body 120 and the box body 110 are firmly closed.

[0102] By making the elastic member 160 abut against different positions of the support member 125 when the cover body 120 is in different positions, the elastic member 160 applies thrusts in different directions to the support member 125, thereby making the cover body 120 firmly maintained at the open extreme position in the open state, and making the cover body 120 and the box body 110 firmly closed in the closed state.

[0103] This embodiment also provides a wireless earphone kit, which includes: a charging box 100 and earphones as in the first aspect, wherein the charging box 100 is used to accommodate the earphones and provide power to the earphones.

[0104] Specifically, the user takes the earphones out of the charging box 100 when using them, and places the earphones in the charging box 100 when the earphones are in an idle state. When the earphones are placed in the charging box 100, the charging box 100 automatically provides power to the earphones.
