Description

Technical Field

[0001] This application belongs to the technical field of headphone devices, and particularly relates to a charging case. Background Art

[0002] In order to improve the aesthetics of wireless headphones, many products with transparent charging cases are available on the current market for headphone components.

[0003] However, for a transparent housing design, it means that the internal structure will also be presented. Especially at the position of the hinge bin, the internal torsion spring structure will be directly observed by users from the outside of the headphone component, affecting the appearance of the headphone component. Therefore, how to block some of the internal structures in the hinge bin has become an urgent problem to be solved. Summary of the Invention

[0004] This application aims to provide a charging case to solve the problem that the internal torsion spring structure in the headphone bin can be directly observed by users from the outside of the headphone component, affecting the appearance of the headphone component in the related art.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of this application provides a charging case, including: a housing assembly, a rotating shaft, a cover body, and an elastic member. Among them, the cover body includes a cover main body and a rotating shaft cover connected to each other, and the cover body is made of a material that allows at least part of the light to pass through;

[0007] A first groove is provided on the housing assembly for accommodating the headphones. A second groove is provided on the side wall of the housing assembly. There is an included angle between the direction from the groove opening to the groove bottom of the second groove and the direction from the groove opening to the groove bottom of the first groove. A rotating shaft is provided in the second groove. An accommodating cavity is also provided in the housing assembly, and the accommodating cavity communicates with the second groove. The rotating shaft cover is hinged to the rotating shaft so that the cover body is rotatably connected to the housing assembly through the rotating shaft, and thus the charging case can be switched between an open state and a closed state;

[0008] In the closed state, the rotating shaft cover blocks the second groove;

[0009] The elastic member is arranged in the accommodating cavity and is connected to the rotating shaft cover. The elastic member provides a rotational restoring force for the rotating shaft;

[0010] Among them, when the charging case is in the open state, the first groove is exposed outside the cover body; when the charging case is in the closed state, the cover body blocks the first groove.

[0011] In an embodiment of the present application, a receiving portion is provided on the housing assembly. When the lid closes the earphone case, since the elastic member is located inside the receiving portion, the elastic member does not need to extend into the earphone case. On this basis, even if the rotating shaft lid has light transmissivity, it is not easy for the user to see the elastic member through the rotating shaft lid. Therefore, there is no need to provide an independent non-transparent component as the rotating shaft lid on the lid, nor is there a need to perform post-processing on the rotating shaft lid to prevent light transmission. This design method does not require adding additional components, making the lid have a high integrity. Without increasing costs and components, the appearance effect of the lid is simple, greatly enhancing the competitiveness of the product.

[0031] Below in conjunction withFigures 1 - 12 Describe a charging case according to an embodiment of the present application.

[0032] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the charging case 100 according to some embodiments of the present application includes a housing assembly 110, a rotating shaft 120, a cover body 130, and an elastic member 140. Among them, the cover body 130 includes a cover main body 132 and a rotating shaft cover 131 that are connected to each other, and the cover body 130 is made of a material that is at least partially light transmissive. A first groove 111 is provided on the housing assembly 110, and the first groove 111 is used to accommodate the earphone. A second groove 112 is provided on the side wall of the housing assembly 110, and there is an included angle between the direction from the notch to the bottom of the second groove 112 and the direction from the notch to the bottom of the first groove 111. The rotating shaft 120 is provided in the second groove 112. An accommodation cavity 113 is also provided in the housing assembly 110, and the accommodation cavity 113 communicates with the second groove 112. The rotating shaft cover 131 is hinged to the rotating shaft 120, so that the cover body 130 is rotatably connected to the housing assembly 110 through the rotating shaft 120, and further enables the charging case 100 to switch between an open state and a closed state. In the closed state, the rotating shaft 120 cover seals the second groove 112. The elastic member 140 is provided in the accommodation cavity 113, and the elastic member 140 is connected to the rotating shaft cover 131. The elastic member 140 provides a rotational restoring force for the rotating shaft 120. Among them, when the charging case 100 is in the open state, the first groove 111 is exposed outside the cover body 130. When the charging case 100 is in the closed state, the cover body 130 seals the first groove 111.

[0033] A first groove 111 is provided on the housing assembly 110, and the earphone can be placed in the first groove 111. The cover body 130 has light transmittance, and light can pass through the cover body 130 and enter the interior of the charging case 100, so that the user can see part of the internal structure of the charging case 100 through the cover body 130.

[0034] The rotating shaft cover 131 and the housing assembly 110 are connected through the rotating shaft 120. A second groove 112 is provided on the housing assembly 110, and the rotating shaft 120 is located in the second groove 112. When the charging case 100 is in the closed state, the cover main body 132 seals the first groove 111, and the rotating shaft cover 131 seals the second groove 112.

[0035] An elastic member 140 is provided between the housing assembly 110 and the rotating shaft cover 131. When the cover body 130 rotates relative to the housing assembly 110, the elastic member 140 will deform, so that the elastic member 140 provides a torsional feel for opening and closing the cover body 130. When the charging case 100 is in the closed state, under the elastic force of the elastic member 140, the cover body 130 is not easily rotated relative to the housing assembly 110 without external force, so as to keep the first groove 111 and the second groove 112 in a sealed and closed state.

[0036] A receiving cavity 113 is provided on the housing assembly 110. When the cover body 130 seals the first groove 111, since the elastic member 140 is located inside the receiving cavity 113, the elastic member 140 does not need to extend into the first groove 111. On this basis, even if the rotating shaft cover 131 has light transmittance, it is not easy for the user to see the elastic member 140 through the rotating shaft cover 131. Therefore, there is no need to provide an independent non-transparent component on the cover body 130 as the rotating shaft cover 131, nor is it necessary to perform post-treatment on the rotating shaft cover 131 to prevent light transmission. This design method does not require adding additional components, making the cover body 130 have high integrity. Without increasing costs and components, the appearance effect of the cover body 130 is simple, greatly improving the competitiveness of the product. Since the elastic member 140 inside the charging case 100 cannot be directly observed by the user from the outside, the influence of the elastic member 140 on the appearance of the charging case 100 is avoided.

[0037] When the charging case 100 is in the open state, the first groove 111 is exposed outside the cover body 130. Since the elastic member 140 is not provided in the first groove 111, it will not affect the appearance of the product. The exposed first groove 111 also facilitates the installation of the rotating shaft 120.

[0038] Exemplarily, the elastic member 140 in this embodiment can be a torsion spring. Of course, in other embodiments, the elastic member 140 can also be other forms of springs.

[0039] When the charging case 100 closes the cover, the torsion spring is located in the area of the housing assembly 110 (solid color), and the torsion spring feature cannot be seen from the cover body 130 (transparent). This design does not require adding any additional components, and at the same time can keep the integrity of the transparent effect of the cover body 130. There is only one rotating shaft 120 on the appearance of the charging case 100, with simple features, good appearance effect and no increase in the overall machine cost. When the charging case 100 is normally opened and used, the torsion spring can move dynamically with the cover body 130 to maintain the feel force within the opening and closing angle, giving consumers a good experience of opening and closing the cover while having appearance competitiveness.

[0040] At the same time, the hidden torsion spring can also be designed in various different forms according to the space characteristics inside the charging case 100 for the scenario of this cover body 130, so as to improve the compatibility of the appearance effect and the feel of opening and closing the cover.

[0041] Combination Figure 3 , Figure 4 and Figure 5 As shown, in some technical solutions, optionally, the first groove 111 has an opening 114, and the opening 114 faces the first direction ( Figure 5 The arrow at A1 in the figure points to the direction in which the housing assembly 110 is opened. In the first direction, a receiving cavity 113 and a second groove 112 are sequentially provided on the housing assembly 110.

[0042] For example, when the opening 114 is facing upward, the accommodating chamber 113 is located at the bottom of the second groove 112, which is equivalent to designing a sunken space at the bottom of the second groove 112 as the accommodating chamber 113. The accommodating chamber 113 does not occupy the space on the side of the second groove 112, which is conducive to making the internal structure of the shell assembly 110 symmetrical and reducing the difficulty of laying out the internal space of the shell assembly 110.

[0043] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some technical solutions, optionally, the shaft cover 131 includes: a shielding portion 133 and a mounting portion 134 , the mounting portion 134 is located on the side of the shielding portion 133 away from the cover body 132 , the shaft 120 is hinged to the shielding portion 133 , and the elastic member 140 is connected to the mounting portion 134 .

[0044] The shielding portion 133 is connected to the cover body 132 , and the mounting portion 134 is connected to the shielding portion 133 . The mounting portion 134 is located at a side of the shielding portion 133 away from the cover body 132 , so the mounting portion 134 is located at the bottom of the shielding portion 133 .

[0045] The elastic member 140 is connected to the mounting portion 134, so the elastic member 140 is connected to a position near the bottom of the rotating shaft cover 131. When the cover body 132 closes the first groove 111, a part of the elastic member 140 will not extend into the second groove 112, thereby better hiding the elastic member 140. When the cover body 132 opens the first groove 111, only a small part of the elastic member 140 extends into the second groove 112, thereby preventing too much elastic member 140 from leaking out and affecting the appearance of the product.

[0046] In a possible application, the rotating shaft cover 131 and the cover body 132 are integrally formed.

[0047] Combination Figure 1 , Figure 4 and Figure 5As shown, in some technical solutions, optionally, the housing assembly 110 includes: an outer shell 115 and an inner lining 116. The inner lining 116 is located inside the outer shell 115, and the accommodation cavity 113 is provided on the inner lining 116. The first side of the elastic member 140 is connected to the inner lining 116, and the second side of the elastic member 140 is connected to the rotating shaft cover 131. When the cover body 130 closes the first groove 111, the distance between the first side of the elastic member 140 and the outer shell 115 is greater than the distance between the second side of the elastic member 140 and the outer shell 115.

[0048] Taking the opening 114 of the first groove 111 facing upward as an example for exemplary illustration, the top of the elastic member 140 is connected to the rotating shaft cover 131, the bottom of the elastic member 140 is located inside the accommodation cavity 113, and the bottom of the elastic member 140 is connected to the inner lining 116. The distance between the bottom of the elastic member 140 and the outer shell 115 is greater than the distance between the top of the elastic member 140 and the outer shell 115. When the cover body 130 closes the first groove 111, the elastic member 140 is distributed along the diagonal side of the accommodation cavity 113, increasing the size of the elastic member 140 within a limited space, which is beneficial to reducing the processing difficulty of the elastic member 140.

[0049] Combined Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, in some technical solutions, optionally, the elastic member 140 includes: a first connecting portion 141, a second connecting portion 142, at least two helical spring coils 145, and a third connecting portion 143. The first connecting portion 141 is connected to the cavity wall of the accommodation cavity 113, the second connecting portion 142 is connected to the mounting portion 134. The second connecting portion 142 includes a first sub-portion 1421 and a second sub-portion 1422. The first sub-portion 1421 and the second sub-portion 1422 are respectively located on both sides of the mounting portion 134. Both the first connecting portion 141 and the second connecting portion 142 extend along the axial direction of the rotating shaft 120. At least two helical spring coils 145 are located between the first connecting portion 141 and the second connecting portion 142. The first helical spring coil 145 among the at least two helical spring coils 145 is connected to the first sub-portion 1421 and the first end of the first connecting portion 141 through the third connecting portion 143. The second helical spring coil 145 among the at least two helical spring coils 145 is connected to the second sub-portion 1422 and the second end of the first connecting portion 141 through the third connecting portion 143.

[0050] By arranging the helical spring coils 145 between the first connecting portion 141 and the second connecting portion 142, when the cover body 130 rotates relative to the housing assembly 110, the helical spring coils 145 are deformed, thereby providing torque to the cover body 130 and improving the feel when rotating the cover body 130. When the charging case 100 is in the closed state, the elastic force provided by the helical spring coils 145 can prevent the cover body 130 from rotating freely.

[0051] Both the first connecting portion 141 and the second connecting portion 142 extend along the axial direction of the rotating shaft 120. That is, there is no included angle between the first connecting portion 141 and the second connecting portion 142, which is convenient for processing and installing the first connecting portion 141 and the second connecting portion 142.

[0052] The first sub - portion 1421 and the second sub - portion 1422 are respectively arranged on both sides of the installation portion 134. When the cover 130 rotates, the forces on both sides of the installation portion 134 are balanced, ensuring the stability of the cover 130 during rotation.

[0053] In some embodiments, optionally, the third connecting portion 143 further includes a third sub - portion 1431 and a fourth sub - portion 1432. The third sub - portion 1431 is respectively connected to the two helical spring coils 145 and the first connecting portion 141, and the fourth sub - portion 1432 is respectively connected to the two helical spring coils 145 and the second connecting portion 142. The distance between the two helical spring coils 145 is less than the distance between the first sub - portion 1421 and the second sub - portion 1422, and / or the distance between the two helical spring coils 145 is less than the length of the first connecting portion 141.

[0054] There are two helical spring coils 145 arranged between the first connecting portion 141 and the second connecting portion 142. The distance between the two helical spring coils 145 is less than the distance between the first sub - portion 1421 and the second sub - portion 1422, and / or less than the length of the first connecting portion 141. The distance between the two sides where the two third sub - portions 1431 are connected to the first connecting portion 141 is relatively large, and the distance between the two sides where the two third sub - portions 1431 are connected to the helical spring coils 145 is relatively small. Similarly, the distance between the two sides where the two fourth sub - portions 1432 are connected to the second connecting portion 142 is relatively large, and the distance between the two sides where the two fourth sub - portions 1432 are connected to the helical spring coils 145 is relatively small. On this basis, when the cover 130 rotates relative to the housing assembly 110, the helical spring coils 145 can generate a large deformation, so as to provide sufficient torque for the cover 130. In some embodiments, optionally, one end of the first helical spring coil 145 is connected to the first sub - portion 1421, and the other end of the first helical spring coil 145 is connected to the first end of the first connecting portion 141 through the third connecting portion 143. One end of the second helical spring coil 145 is connected to the second sub - portion 1422, and the other end of the second helical spring coil 145 is connected to the second end of the first connecting portion 141 through the third connecting portion 143. Among them, the distances between the first sub - portion 1421 and the second sub - portion 1422 and the cover 130 are both less than the distance between the first connecting portion 141 and the cover 130.

[0055] The distances between the first sub - part 1421 and the second sub - part 1422 and the cover 130 are relatively small, while the distance between the first connecting part 141 and the cover 130 is relatively large. This is equivalent to installing most of the structure of the elastic member 140 away from the cover 130, thus preventing the elastic member 140 from being seen by the user on the appearance of the charging case and ensuring the overall aesthetic appearance of the product.

[0056] Combined with Figure 8 , Figure 9 and Figure 10 As shown, in a possible application, based on the structure of the elastic member 140 in Figure 8 , a part of the fourth sub - part 1432 can be bent. From the helical spring coil 145 to the second connecting part 142, the distance between the two fourth sub - parts 1432 first increases and then remains unchanged, so that the overall width of the elastic member 140 can be reduced.

[0057] In some embodiments, optionally, the third connecting part 143 has a bent part 1433 that protrudes in a direction away from the cover 130.

[0058] A part of the structure on the third connecting part 143 is bent, and the bend on the third connecting part 143 protrudes in a direction away from the cover 130, that is, the third connecting part 143 bends in a direction away from the cover 130. On this basis, sufficient lever arms can be provided for the helical spring coil 145, so that the helical spring coil 145 can produce a large deformation.

[0059] Combined with Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, in some technical solutions, optionally, the accommodation cavity 113 includes a third groove 1191 and a fourth groove 1192 arranged in parallel. The third groove 1191 is provided on both sides of the fourth groove 1192, and the depth of the third groove 1191 is greater than that of the fourth groove 1192. The first connecting part 141 is arranged in the fourth groove 1192 and is connected to the bottom of the fourth groove 1192. The third connecting part 143 is arranged in the third groove 1191, and the bent part is close to the bottom of the third groove 1191.

[0060] When the internal layout of the housing assembly 110 is relatively compact, the space for arranging the accommodation cavity 113 is limited. In this embodiment, the accommodation cavity 113 is divided into three grooves. Two of the grooves are two third grooves 1191, and a fourth groove 1192 is arranged between the two third grooves 1191. The depth of the third groove 1191 is relatively large, and the depth of the fourth groove 1192 is relatively small, so that the third groove 1191 can be adapted to the third connecting part 143, and the third groove 1191 provides sufficient accommodation space for the third connecting part 143.

[0061] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some technical solutions, optionally, the charging box 100 further includes: a Hall magnet 150, a magnetic conductive member 160 and a Hall device 170, the Hall magnet 150 is connected to the shaft cover 131, and the Hall magnet 150 is located on the side of the shaft cover 131 away from the cover body 132. The magnetic conductive member 160 is arranged in the housing assembly 110, and the magnetic conductive member 160 is arranged along the first groove 111 from the groove opening to the groove bottom direction ( Figure 4 The Hall device 170 is disposed in the housing assembly 110, and the Hall device 170 is located on the side of the magnetic conductive member 160 away from the Hall magnet 150. The magnetic conductive member 160 is used to transfer the magnetic field of the Hall magnet 150 to the Hall device 170. In the closed state, the Hall magnet 150 faces the magnetic conductive member 160.

[0062] When the cover 130 opens or closes the first groove 111, the position of the shaft cover 131 relative to the housing assembly 110 changes. The shaft cover 131 is provided with a Hall magnet 150. When the position of the shaft cover 131 changes, the position of the Hall magnet 150 also changes.

[0063] A magnetic conductive component 160 and a Hall device 170 are also provided in the shell assembly 110. The magnetic conductive component 160 is a component for guiding and transmitting the magnetic field. The magnetic conductive component 160 can transmit the magnetic field of the Hall magnet 150 to the Hall device 170 by magnetic induction. When the position of the Hall magnet 150 changes, the magnetic induction between the magnetic conductive component 160 and the Hall device 170 will change, so that the Hall device 170 can receive the magnetic field change of the Hall magnet 150, realize the magnetic field triggering of the Hall device 170, and thus derive the position change of the cover body 130, so that the controller in the charging box 100 can determine whether the cover is currently in an open state.

[0064] The Hall magnet 150 is arranged on the side of the hinge cover 131 away from the cover body 132. When the cover body 130 closes the first groove 111, the Hall magnet 150 is located at the bottom of the hinge cover 131. It is difficult for the user to see the Hall magnet 150 from the outside of the charging box 100, so there is no need to set a structure to shield the Hall magnet 150 on the hinge cover 131, which reduces the processing difficulty of the cover body 130 and avoids affecting the appearance of the product.

[0065] In some embodiments, optionally, one end of the magnetic conductive member 160 facing the Hall magnet 150 is located in the accommodating cavity 113 .

[0066] One end of the magnetic conductive member 160 adjacent to the Hall magnet 150 is located in the accommodation cavity 113. Therefore, the magnetic conductive member 160 does not extend into the second groove 112, and it is not easy for users to see the magnetic conductive member 160 from the outside of the charging case 100, avoiding the magnetic conductive member 160 from affecting the appearance of the product.

[0067] As Figure 4 shown, in some technical solutions, optionally, the first groove 111 includes a first earphone bin 117 and a second earphone bin 118, and the first earphone bin 117 and the second earphone bin 118 are distributed along the axial direction of the rotating shaft ( Figure 4 the arrow direction at A3 in the figure). On the side of the Hall magnet 150 facing the magnetic conductive member 160, chamfers 152 are provided on both sides along the axial direction of the rotating shaft 120, and the chamfers 152 avoid the first earphone bin 117 and the second earphone bin 118.

[0068] The side of the Hall magnet 150 that generates magnetic induction with the magnetic conductive member 160 is named the induction side.
