[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The core of the present invention is to provide an earphone charging box, which can facilitate the removal of the earphone. Another core of the present invention is to provide a Bluetooth earphone assembly including the above earphone charging box, and the charging box can facilitate the removal of the earphone.

[0048] It should be noted that when an element is referred to as "fixed" to another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a central element at the same time. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0049] In a specific embodiment of the earphone charging box provided by the present invention, it includes a lower shell 5 and an upper cover 1, a sliding key 3 and a ejection member.

[0050] The lower shell 5 is used to place the earphone 2, which can be a Bluetooth earphone. The earphone slot in the lower shell 5 fixes and charges the earphone 2, and the earphone 2 is placed in the lower shell 5 through the lower shell opening 51 of the lower shell 5. The upper cover 1 is movably connected to the lower shell 5, so that the upper cover can open or cover the lower shell opening 51 of the lower shell 5. At the same time, a fixing structure is provided between the upper cover 1 and the lower shell 5, so that the upper cover 1 is fixed to the lower shell 5 when covering the lower shell opening 51. The fixing structure can be a snap-on fixing structure or a magnetic fixing structure.

[0051] The sliding key 3 is slidably connected to the lower shell 5. At least part of the structure on the sliding key 3 is exposed on the lower shell 5. The user can push the sliding key 3 to slide relative to the lower shell 5. Figure 5 and Figure 7 In the position shown, the sliding direction is up and down. The outer surface of the sliding key 3 is preferably provided with friction lines to facilitate the user to push.

[0052] The ejector can move in the same direction driven by the slide key 3, that is, when the slide key 3 slides toward the upper cover 1, it can drive the ejector to slide toward the upper cover 1; when the slide key 3 slides in the direction away from the upper cover 1, it can drive the ejector to slide away from the upper cover 1. It should be noted that the "same direction" here is limited to the same movement direction of the slide key 3 and the ejector, but the speed of the two at the same time can be the same or different. In addition, the slide key 3 can only drive the ejector to move within a certain range within its sliding stroke. For example, when the slide key 3 starts to slide toward the upper cover 1 from the initial position, the upper cover 1 is opened, and the ejector is stationary in the lower shell 5. When the slide key 3 slides a first distance (the first distance is less than the sliding stroke of the slide key 3), if it continues to slide in the original direction, the ejector will move toward the upper cover 1 driven by the slide key 3; or, each position where the slide key 3 moves within its sliding stroke drives the ejector to move.

[0053] After the earphone 2 is placed in the lower shell 5, the ejector contacts the earphone 2, and the upper cover 1 covers the lower shell opening 51. When the earphone 2 needs to be taken out, the sliding key 3 is pushed toward the upper cover 1. During the sliding key 3 sliding toward the upper cover 1, the upper cover 1 covering the lower shell opening 51 can be pushed open, thereby realizing the cover opening operation. It should be noted that the sliding key 3 pushing the upper cover 1 open specifically refers to the position change of the upper cover 1 relative to the lower shell 5, such as rotation or movement, and the specific rotation angle or movement distance is not limited.

[0054] In addition, when the sliding key 3 slides toward the upper cover 1, the sliding key 3 drives the ejection member to move toward the upper cover 1. The ejection member can push the earphone 2 toward the upper cover 1 for a distance, which is convenient for the user to take out the earphone and improves the user experience.

[0055] It can be seen that for the earphone charging box in the closed state, the cover can be opened directly by pushing the sliding key 3, without the user having to manually open the cover. The earphone 2 can also be automatically pushed out of the lower shell 5 for a certain distance through the ejection member, which greatly facilitates the user to take out the earphone 2.

[0056] For further information, please refer to Fig. 9 , Fig.16 and Fig.17 The ejection member is an earphone bracket 4 slidably connected to the lower shell 5. The earphone bracket 4 is provided with a microphone rod groove 41 for accommodating at least part of the microphone rod 21 of the earphone 2. The bottom of the microphone rod groove 41 can support the bottom of the microphone rod 21. The microphone rod groove 41 is preferably designed to be contoured with the microphone rod 21 to improve the stability of the placement of the earphone 2. Compared with the embodiment in which an ejection member is additionally provided in the microphone rod groove 41, the present embodiment can directly use the bottom of the microphone rod groove 41 to drive the earphone 2 to move toward the upper cover 1, so the structure is simple and easy to process and assemble.

[0057] For further information, please refer to Figures 15 to 17 The earphone bracket 4 includes two parallel mounting posts 43 and a connecting rod 44 connected between the two mounting posts 43. Each mounting post 43 is provided with a microphone rod slot 41. Figure 5 , Figure 7 and Fig.17 As shown, the space between the connecting rod 44 and the two mounting posts 43 forms a U-shaped groove 45 opening toward the sliding key 3, and the mounting post 43 is connected to the sliding key 3 through a transmission structure, and at least part of the transmission structure is disposed in the U-shaped groove 45. The arrangement of the U-shaped groove 45 provides an installation space or a moving space for the transmission structure or other structures in the lower shell 5, and at the same time, since the transmission structure is disposed between the two mounting posts 43, the stability of the movement of the earphone bracket 4 can be improved.

[0058] Among them, for the setting of the battery, optionally, a wireless charging battery is set in the lower shell 5 to wirelessly charge the earphone 2; or, a contact charging battery is set in the lower shell 5, specifically, by setting a through hole on the microphone rod slot 41, the battery is fixed to the lower shell 5, that is, the battery remains stationary relative to the lower shell 5, when the earphone bracket 4 moves away from the upper cover 1, the battery in the lower shell 5 extends into the microphone rod slot 41 through the through hole and is gradually inserted into the earphone 2 for contact charging; or, the output end of the battery set in the lower shell 5 is an electrical contact, which is directly fixed to the bottom of the microphone rod slot 41, and can move synchronously with the microphone rod slot 41, and can be charged after the earphone is placed in the microphone rod slot 41.

[0059] Furthermore, a main bracket 53 is fixedly disposed in the lower shell 5. Figure 5 , Figure 6 , Fig.13 and Fig.14 The main bracket 53 includes a support plate 531 and a side plate 54 fixed to the support plate 531. The support plate 531 and the side plate 54 are arranged side by side in a direction perpendicular to the movement of the earphone bracket 4. The earphone bracket 4 is arranged between the bottom of the lower shell 5 and the support plate 531. The bottom of the lower shell 5 and the support plate 531 limit the movement range of the earphone bracket 4. In addition, please refer to Fig.14 and Fig.15 The headphone bracket 4 is provided with a bracket slide 46, and the main bracket 53 is provided with a bracket slider 534. The bracket slide 46 is slidably connected with the bracket slider 534. The bracket slide 46 and the bracket slider 534 extend from the bottom of the lower shell 5 toward the upper shell 1 to guide the headphone bracket 4 as the slide key 3 slides. In addition, a slide key avoidance groove 52 is provided through the lower shell 5. The headphone bracket 4 and the slide key avoidance groove 52 are respectively arranged on both sides of the side plate 54, and the side plate 54 can specifically cover the slide key avoidance groove 52.

[0060] Preferably, the support plate 531 is provided with a microphone rod through hole 532 corresponding to the microphone rod slot 41, and the support plate 531 is provided with an earplug slot 533 for positioning the earplug 22 of the earphone 2 on one side close to the upper cover 1. The earplug slot 533 is preferably designed to be similar to the earplug 22, and the earplug slot 533, the corresponding microphone rod through hole 532, and the microphone rod slot 41 together constitute an earphone slot. When the earphone 2 is placed in the lower shell 5, as shown in FIG. Figure 5 As shown, the microphone rod 21 extends into the microphone rod groove 41 through the microphone rod through hole 532, and the earplug 22 falls into the earplug groove 533. The earplug groove 533 can position the earplug 22, so that the earphone 2 is stably placed in the lower shell 5.

[0061] Among them, preferably, please refer to Figure 4 , Fig.11 and Fig.12 The sliding key 3 is arranged in the sliding key avoidance groove 52 and its outer surface is sunken into the outer surface of the lower shell 5. The sliding key 3 is slidably connected to the side plate 54. By setting the sliding key avoidance groove 52, the sliding key 3 can be prevented from being damaged by impact, or from being pushed in an accidental situation such as falling, causing the upper cover 1 to be accidentally opened and the earphone 2 to fall out.

[0062] Furthermore, when the upper cover 1 is closed on the lower shell opening 51, Figure 1 As shown, the sliding key 3 is in the initial position on the lower shell 5. During the process of sliding the sliding key 3 from the initial position toward the upper cover 1 to the preset opening position, as shown in FIG. Figure 2 As shown, the sliding key 3 can push open the upper cover 1 covering the lower shell opening 51 and the ejector remains in the lower shell 5. When the sliding key 3 continues to move from the preset cover opening position toward the upper cover 1, as shown in FIG. Figure 3 As shown, the ejector can move in the same direction driven by the sliding key 3, thereby ejecting the earphone 2 toward the upper cover 1. When the sliding key 3 does not push the upper cover 1 open, the position of the earphone 2 in the lower shell 5 remains unchanged, which can prevent the earphone 2 from colliding with the upper cover 1 and causing damage.

[0063] Furthermore, the lower shell 5 or a component fixedly connected to the lower shell 5 is provided with a transmission through hole 541, as shown in FIG. Fig.11 As shown, the transmission through hole 541 is opened on the side plate 54 of the main bracket 53. Fig.10 A sliding key rack 31 is fixed on the sliding key 3, and the sliding key rack 31 extends into the lower shell 5 through the transmission through hole 541. The sliding key rack 31 is connected to the ejection member through the gear transmission member in the lower shell 5. The sliding key rack 31 and the gear transmission member constitute a transmission structure between the ejection member and the sliding key 3. The gear transmission is adopted, and the transmission accuracy is high.

[0064] Specifically, please refer to Fig.10, a straight rod 32 is connected to one end of the sliding key rack 31 in the extending direction close to the upper cover 1, and the straight rod 32 can provide an idle stroke between the sliding key rack 31 and the gear transmission member. In the process of the sliding key 3 moving from the initial position toward the upper cover 1, the straight rod 32 first passes through the gear transmission member. In this process, the sliding key 3 can push open the upper cover 1 covering the lower shell opening 51, but since there is no transmission relationship between the straight rod 32 and the gear transmission member, the position of the gear transmission member remains unchanged, and the position of the ejector in the lower shell 5 remains unchanged; after the sliding key 3 moves to the sliding key rack 31 and meshes with the gear rotating member, the sliding key 3 continues to move toward the upper cover 1, the gear transmission member is driven, and the ejector moves toward the upper cover 1 driven by the sliding key 3.

[0065] Specifically, in order to ensure the smooth sliding of the sliding key 3, a sliding key guide hole 542 may be provided on the side plate 54. Fig.11 As shown, correspondingly, a sliding key guide block 33 is provided on the sliding key 3, as shown in FIG. Fig.10 As shown, the key guide block 33 is slidably connected to the key guide hole 542 to guide the sliding direction of the key 3 on the lower shell 5. In addition, the key guide block 33 is clamped on the side plate 54 to prevent the key 3 from being separated from the lower shell 5. Specifically, the key guide hole 542 is a straight hole extending from the bottom of the lower shell to the upper cover.

[0066] Furthermore, the gear transmission member includes an ejector rack 42 fixed on the ejector and a speed gear 7 rotatably connected to the gear bracket 55 in the lower shell 5. The sliding key rack 31 and the ejector rack 42 are both meshed and connected to the speed gear 7, thereby adjusting the relationship between the moving distance of the sliding key 3 and the moving distance of the ejector, thereby improving the efficiency of the ejector being ejected.

[0067] Specifically, Fig. 9 As shown, the key rack 31 is arranged in parallel with the ejector rack 42, and specifically extends from the lower shell 5 toward the upper cover. The speed change gear 7 includes a coaxially arranged small gear and a large gear, and the gear bracket 55 is fixed to the support plate 531. Figure 4 As shown, the large gear meshes with the ejector rack 42, and the small gear meshes with the key rack 31, thereby increasing the moving speed of the ejector, so that the key 3 moves a small distance, and the ejector moves a larger distance accordingly. In addition, the ejector rack 42 is fixed to one of the two mounting posts 43, and at least part of the ejector rack 42 is located in the U-shaped groove 45 formed by the earphone bracket 4. When the earphone bracket 4 slides, Figure 5 As shown, the U-shaped groove 45 provides an escape passage for the speed gear 7 to pass through, thereby preventing the earphone bracket 4 and the speed gear 7 from colliding with each other.

[0068] Furthermore, an elastic member 6 is provided in the lower shell 5, and the resetting force of the elastic member 6 makes the ejection member have a tendency to move away from the upper cover 1, so that the ejection member can be automatically reset.

[0069] Optionally, the elastic member 6 is a compression spring abutting between the support plate 531 and the connecting rod 44. Figure 7 As shown, during the process of the ejector moving along with the sliding key 3 toward the upper cover 1, the elastic member 6 deforms and increases to accumulate elastic potential energy; after the user releases the sliding key 3, the elastic member 6 resets and drives the ejector to move away from the upper cover 1. At the same time, the ejector drives the sliding key 3 to move away from the upper cover 1 through the transmission structure.

[0070] Furthermore, the lower shell 5 is also provided with a magnetic attraction member for magnetically fixing the earphone 2 in the lower shell 5. Correspondingly, the earphone 2 paired with the earphone charging box is provided with a corresponding earphone magnetic member. Depending on the type of earphone magnetic member, the magnetic attraction member in the lower shell 5 can be set to a material that can be magnetically attracted, such as an iron sheet, or a permanent magnet. In addition, as for the setting position of the magnetic attraction member, it can be directly fixed on the pushing member, for example, embedded in the microphone rod groove 41, or it can be fixed to the bottom of the lower shell 5. Of course, it can also be other positions that can magnetically attract the earphone 2 during the installation of the earphone 2. By setting the magnetic attraction member, the stability of the earphone 2 in the lower shell 5 can be further improved, and the speed of putting the earphone 2 into the lower shell 5 can be increased.

[0071] Furthermore, the upper cover 1 is hinged on the hinge axis of the lower shell 5, and the slide key 3 is slidably connected to the wall surface of the lower shell 5 opposite to the hinge axis, so that the force arm between the slide key 3 and the hinge axis is relatively long, which saves effort when pushing open the upper cover 1. A clamping structure is specifically provided between the upper cover 1 and the lower shell 5. When the upper cover 1 covers the lower shell opening 51, the upper cover 1 and the lower shell 5 are clamped and fixed by the clamping structure. In the process of the slide key 3 sliding from the initial position to the upper cover 1, after the slide key 3 presses the upper cover 1 to release the clamping of the clamping structure, the slide key 3 continues to slide in the original direction, and the upper cover 1 will rotate around the hinge axis. Specifically, the upper cover 1 can automatically continue to rotate to the maximum opening angle under the action of inertia after being pushed to a certain opening angle by the slide key 3, such as Figure 6 As shown; alternatively, after the upper cover 1 is pushed to a certain opening angle by the sliding key 3, the upper cover 1 can be manually opened to a maximum opening angle.

[0072] In the earphone charging box provided in this embodiment, when assembling, the upper cover hinge bracket 56, the sliding key 3, the battery 59, the mainboard 510, the elastic member 6, and the earphone bracket 4 are respectively assembled to the main bracket 53, and the speed change gear 7 is assembled to the gear bracket 55 by the screw 58, and the gear bracket 55 is assembled to the main bracket 53, thereby obtaining the main bracket assembly in the lower shell 5. The upper cover 1 is hinged to the main bracket assembly by the pin 57, and the lower shell 5 is assembled to the main bracket assembly, thereby obtaining the overall structure of the charging box.

[0073] During use, when the sliding key 3 is pushed from the initial position toward the upper cover 1, the sliding key 3 will directly push the upper cover 1 open. Figure 2 After the upper cover 1 is opened, the sliding key 3 is pushed to slide in the original direction, and the sliding key rack 31 on the sliding key 3 will drive the speed change gear 7 to rotate, and the speed change gear 7 drives the ejection member rack 42 on the earphone bracket 4 to move upward, forcing the earphone bracket 4 to move upward, and the earphone bracket 4 pushes the earphone 2 upward, so as to achieve the following effect. Figure 3 In the state shown, the earphone 2 is now free from the magnetic attraction of the charging box and can be easily taken out.

[0074] When the user releases the sliding key 3, the thrust on the sliding key 3 is released, and the elastic restoring force of the elastic member 6 provides power to drive the earphone holder 4 to move away from the upper cover for restoration. The earphone holder 4 moves away from the upper cover while driving the speed gear 7 to rotate. The speed gear 7 drives the sliding key 3 to move away from the upper cover for restoration. The earphone holder 4 is restored. At this time, the earphone 2 can be placed in the charging box again. The magnetic suction part of the charging box absorbs the earphone 2, and the upper cover 1 can be closed and returned to the Figure 1 The sliding key 3 is reset to the initial position.

[0075] In another specific embodiment of the earphone charging box provided by the present invention, the sliding key 3 can be directly fixedly connected to the ejection member to drive the ejection member to move. In addition, an earphone slot for placing the earphone 2 is provided in the lower shell 5, and the ejection member is movably provided at the bottom of the earphone slot. When the sliding key 3 moves toward the upper cover 1, the ejection member pushes the earphone 2 to move in the earphone slot toward the upper cover 1. In addition, the upper cover 1 and the lower shell 5 can be set as a split structure. After the sliding key 3 pushes the upper cover 1 to release the clamping fixation between the upper cover 1 and the lower shell 5, the upper cover 1 can be separated from the lower shell 5 as a whole.

[0076] In addition to the above-mentioned earphone charging box, the present invention also provides a Bluetooth earphone assembly, which includes a charging box and a Bluetooth earphone, and the earphone charging box and the Bluetooth earphone are adapted. Among them, the charging box can be specifically the earphone charging box provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly.
