[0039] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected", "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0040] Such as Figure 1As shown in the figure, the charging case provided by an embodiment of the present utility model can charge the earphones. Among them, the earphones can be in-ear earphones or open earphones, and the earphones can be configured with functions such as call noise reduction and / or artificial intelligence noise reduction. At the same time, functions such as stereo surround can also be configured.

[0041] It should be noted that in other embodiments, the charging case can also be used to charge other electronic devices, such as electronic watches, electronic rings, electronic glasses, and so on.

[0042] As Figures 1 to 3 shown, the charging case includes a housing 100, a supporting member 200, a charging post 300, and a sealing member 400.

[0043] Combined Figure 1 with Figure 2 , the housing 100 is a hollow structure with an opening, the supporting member 200 is arranged in the housing 100, and the supporting member 200 covers the opening of the housing 100; among them, a receiving portion 210 for accommodating the device to be charged is provided on the outer side of the supporting member 200.

[0044] It should be noted that the outer side of the supporting member 200 faces the hollow area of the housing 100, the inner side of the supporting member 200 faces the hollow area of the housing 100, the receiving portion 210 is a receiving groove opened on the outer side of the supporting member 200, and the receiving groove is used for placing the device to be charged to position the device to be charged.

[0045] Combined Figure 2 with Figure 3 , further, the supporting member 200 is provided with a mounting hole 220 penetrating the wall surface of the receiving portion 210. Specifically, the mounting hole 220 extends inward from the wall surface of the receiving portion 210 and penetrates the supporting member 200; the charging post 300 is inserted through the mounting hole 220, and at least part of the charging post 300 extends out of the outer end of the mounting hole 220.

[0046] It should be noted that the outer end of the mounting hole 220 is formed on the wall surface of the receiving portion 210, that is, the outer end of the mounting hole 220 penetrates the outer side of the supporting member 200, and the inner end of the mounting hole 220 penetrates the inner side of the supporting member 200.

[0047] It can be understood that a main board 500 is arranged in the housing 100, the main board 500 is located inside the supporting member 200, one end of the charging post 300 is connected to the main board 500, and the charging post 300 is inserted through the mounting hole 220 and extends out of the outer end of the mounting hole 220. Among them, a battery electrically connected to the main board 500 is also arranged in the housing 100. When the device to be charged is placed in the receiving portion 210, the charging terminal on the device to be charged contacts the charging post 300, so that the battery charges the device to be charged.

[0048] As Figure 3 shown, the seal 400 is disposed within the accommodating portion 210. The seal 400 is sleeved outside the charging post 300 and is in sealing cooperation with the charging post 300. Moreover, the seal 400 also covers the outer end of the mounting hole 220 and is sealingly connected around the outer end of the mounting hole 220.

[0049] It can be understood that the seal 400 is used to seal the gap between the charging post 300 and the hole wall of the mounting hole 220, thereby reducing the risk that external liquid substances (such as water and sweat) enter the interior of the charging box through the hole wall of the charging post 300 and the mounting hole 220 and damage related components.

[0050] Combined with Figure 3 and Figure 7 , it should be noted that the seal 400 is provided with a middle hole 440. The charging post 300 passes through the middle hole 440 and is in interference fit with the hole wall of the middle hole 440. In this way, the sealing cooperation between the seal 400 and the charging post 300 can be achieved; in other embodiments, a sealing glue can be coated between the hole wall of the middle hole 440 and the side wall of the charging post 300, thereby achieving the sealing cooperation between the seal 400 and the charging post 300.

[0051] Combined with Figure 3 and Figure 5 , in some embodiments, the charging post 300 includes an elastic member 310 passing through the mounting hole 220 and a conductive head 320 connected to one end of the elastic member 310. The conductive head 320 is disposed within the mounting hole 220, and at least a part of the conductive head 320 extends out of the outer end of the mounting hole 220. The conductive head 320 can move along the axial direction of the mounting hole 220.

[0052] It can be understood that when the device to be charged is placed in the accommodating portion 210, the conductive head 320 is pressed down, and at the same time, the elastic member 310 is also compressed. At this time, the elastic member 310 applies an upward acting force on the conductive head 320 by virtue of its own elastic force, so that the conductive head 320 is in tight contact with the charging terminal on the device to be charged, reducing the risk of poor contact.

[0053] Specifically, the charging post 300 further includes a guide sleeve 330 passing through the mounting hole 220. One end of the guide sleeve 330 is connected to the main board 500. The elastic member 310 is disposed within the guide sleeve 330. The conductive head 320 is disposed within the guide sleeve 330 and abuts against the elastic member 310, and at least a part of the conductive head 320 extends out of the other end of the guide sleeve 330. Among them, the elastic member 310 can be a spring or a spring piece.

[0054] It should be noted that the materials of the guide sleeve 330, the elastic member 310, and the conductive head 320 are all conductive materials. For example, copper, electrically conductive steel, etc.

[0055] Further, the sealing member 400 is made of an elastic material, and the sealing member 400 is sleeved on the conductive head 320 and is in interference fit with the conductive head 320.

[0056] It can be understood that during the process of the conductive head 320 being pressed down or reset under the action of the elastic member 310, the conductive head 320 will move axially along the mounting hole 220. By making the material of the sealing member 400 an elastic material and making the sealing member 400 in interference fit with the conductive head 320, when the conductive head 320 moves axially along the mounting hole 220, the sealing member 400 can be driven to undergo elastic deformation, and the sealing member 400 will not hinder the axial movement of the conductive head 320 along the mounting hole 220.

[0057] It should be noted that the sealing member 400 is sleeved outside the conductive head 320, which can prevent liquid substances from entering the inside of the charging column 300 and causing the elastic member 310 and the guide sleeve 330 to rust.

[0058] As Figure 4 shown, further, the sealing member 400 includes a first sealing portion 410 and a second sealing portion 420 connected to the first sealing portion 410. The first sealing portion 410 is sleeved outside the second sealing portion 420, and the first sealing portion 410 is connected around the outer end of the mounting hole 220. The second sealing portion 420 is sleeved outside the conductive head 320 and is in interference fit with the conductive head 320.

[0059] Further referring to Figure 7 , even further, the second sealing portion 420 is elastically connected to the first sealing portion 410.

[0060] Specifically, the sealing member 400 is made of rubber material. The first sealing portion 410 and the second sealing portion 420 are of an integral structure, and the second sealing portion 420 is inclined with respect to the first sealing portion 410. In this way, the second sealing portion 420 can undergo elastic deformation with respect to the first sealing portion 410.

[0061] Further, the sealing member 400 is provided with a groove 450, and the groove 450 passes through the connection portion of the first sealing portion 410 and the second sealing portion 420. It can be understood that the setting of the groove 450 can make the second sealing portion 420 more easily undergo elastic deformation as the conductive head 320 moves up and down.

[0062] As Figure 4 shown, further, the wall surface of the accommodating portion 210 is also provided with a positioning groove 230 arranged around the outer end of the mounting hole 220, and the first sealing portion 410 is arranged in the positioning groove 230. The setting of the positioning groove 230 can improve the positioning accuracy of the first sealing portion 410.

[0063] In some embodiments, the first sealing portion 410 is fixed to the positioning groove 230 by bonding.

[0064] Wherein, on one side of the positioning groove 230 close to the mounting hole 220, a glue storage groove 231 is provided around the mounting hole 220. In this way, during the process of applying glue to the bottom wall of the positioning groove 230, or when the first sealing portion 410 presses on the adhesive in the positioning groove 230, the glue flowing towards the mounting hole 220 will enter the glue storage groove 231. Thus, the risk of glue flowing between the charging post 300 and the hole wall of the mounting hole 220 can be reduced, thereby preventing the conductive head 320 from being fixed, and also preventing the glue from flowing into the interior of the charging box and damaging related components.

[0065] Combined with Figure 8 and Figure 9 , further, the first sealing portion 410 is provided with a partition groove 413 coaxially arranged with the mounting hole 220. The partition groove 413 divides the first sealing portion 410 into a first portion 411 close to the second sealing portion 420 and a second portion 412 far from the second sealing portion 420; wherein, a bonding layer (formed by solidification of glue) is provided on the bottom wall of the positioning groove 230, and the bonding layer is also bonded to the first portion 411 and the second portion 412 respectively. The wall surface of the partition groove 413 opposite to the bonding layer is arranged at a distance from the bonding layer.

[0066] As Figure 10 shown, it can be understood that in the case where the partition groove 413 is not provided, the lower surface of the entire first sealing portion 410 is bonded to the bonding layer. As the number of times the charging post 300 moves up and down repeatedly increases, since the bonding effect of the bonding layer on each part of the first sealing portion 410 may be different in the circumferential direction of the charging post 300, there may be a problem that the bonding layer fails in some places and remains effective in some places. Therefore, in the circumferential direction of the charging post 300, the abutting force between the second sealing portion 420 and the conductive head 320 is different. Especially when the conductive head 320 rises to the highest value, there may be a problem that part of the second sealing portion 420 cannot be closely matched with the conductive head 320, resulting in a poor sealing performance.

[0067] As Figures 8 to 10As shown, in the present application, after the partition groove 413 is provided on the seal 400, the adhesive layer cannot penetrate into the partition groove 413 and bond to the top wall of the partition groove 413. Thus, on the first sealing portion 410, the position of the partition groove 413 is not bonded to the adhesive layer, and only the first part 411 and the second part 412 are bonded to the adhesive layer. As the number of times the charging post 300 moves up and down repeatedly increases, since the bonding effect of the adhesive layer on each part of the first part 411 may be different in the circumferential direction of the charging post 300, there may be a problem that the adhesive layer fails in some places and remains effective in some places. Therefore, it will cause the abutting force between the second sealing portion 420 and the conductive head 320 to be different in the circumferential direction of the charging post 300. Especially when the conductive head 320 rises to the highest value, there will be a problem that part of the second sealing portion 420 cannot closely cooperate with the conductive head, resulting in a poor sealing problem. When this problem occurs, the user can manually tear the seal 400 to separate the entire first part 411 from the adhesive layer. At this time, only the second part 411 is bonded to the adhesive layer. In the circumferential direction of the charging post 300, the second part 412 is bonded to the adhesive layer more evenly, so that the abutting force between the second sealing portion 420 and the conductive head 320 is also more even in the circumferential direction of the charging post 300, and the service life of the seal 400 can be extended.

[0068] Combined with Figure 8 and Figure 9 , further, the second part 412 is provided with a glue groove 414, and the adhesive layer also extends into the glue groove 414 and bonds to the groove walls of the glue groove 414. Thus, it is equivalent to increasing the contact area between the adhesive layer and the second part 412 and improving the bonding reliability of the second part 412. It can be understood that the depth of the glue groove 414 is less than the depth of the partition groove 413. Thus, when bonding the seal 400, the glue can penetrate into the glue groove 414 and bond to the groove walls of the glue groove 414, rather than connecting to the top wall of the partition groove 413.

[0069] Specifically, the glue groove 414 extends along the radial direction of the seal 400, and the number of the glue grooves 414 is multiple, and the multiple glue grooves 414 are arranged at intervals in the circumferential direction of the seal 400.

[0070] Combined with Figure 6 and Figure 7 , in some embodiments, an assembly groove 321 is provided on the outer side portion of the conductive head 320, and the seal 400 is inserted into the assembly groove 321.

[0071] It can be understood that the assembly groove 321 is an annular groove, and the seal 400 is inserted into the assembly groove 321. In this way, when the conductive head 320 moves along the axial direction of the mounting hole 220, the upper side wall or the lower side wall of the assembly groove 321 can also push the seal 400, reducing the risk of relative sliding between the seal 400 and the conductive head 320, and thus reducing the risk of wear of the seal 400.

[0072] Furthermore, the seal 400 is provided with a sealing protrusion 430. The protruding direction of the sealing protrusion 430 is parallel to the axial direction of the mounting hole 220, and the sealing protrusion 430 is in interference fit with the side wall of the assembly groove 321.

[0073] In some embodiments, the sealing protrusion 430 protrudes from the upper surface of the seal 400 and is in interference fit with the upper side wall of the assembly groove 321. In other embodiments, the sealing protrusion 430 protrudes from the lower surface of the seal 400 and is in interference fit with the lower side wall of the assembly groove 321. In this way, the sealing effect of the seal 400 can be further improved. In addition, the protruding direction of the seal 400 is parallel to the axial direction of the mounting hole 220, that is, the protruding direction of the seal 400 is parallel to the moving direction of the conductive head 320. In this way, when the conductive head 320 moves along the axial direction of the mounting hole 220, the problem of relative sliding between the sealing protrusion 430 and the conductive head 320 can be improved, and the risk of wear of the sealing protrusion 430 can be reduced.

[0074] It can be understood that the sealing protrusion 430 is annular and is coaxially arranged with the mounting hole 220.

[0075] In the charging box of the present utility model, a receiving portion 210 is provided on the outer portion of the supporting member 200. The receiving portion 210 is used for placing the device to be charged to position the device to be charged. When the device to be charged is placed in the receiving portion 210, the charging terminal on the device to be charged contacts the charging post 300, thereby realizing the charging of the device to be charged. Among them, the seal 400 is arranged in the receiving portion 210. The seal 400 is sleeved outside the charging post 300 and is in sealing cooperation with the charging post 300, and the seal 400 also covers the outer end of the mounting hole 220 and is sealingly connected around the outer end of the mounting hole 220. The seal 400 is used to seal the gap between the charging post 300 and the hole wall of the mounting hole 220, thereby reducing the risk that external liquid substances (such as water and sweat) enter the interior of the charging box through the hole wall of the charging post 300 and the mounting hole 220 and damage related components. Similarly, the seal 400 is sleeved outside the conductive head 320, which can prevent liquid substances from entering the interior of the charging post 300 and causing the elastic member 310 and the guide sleeve 330 to rust.
