The movable linkage assembly is used to drive the earphone holder to move relative to the second housing when the first housing and the second housing rotate relative to each other, so as to take and place the earphone.

[0038] The above-mentioned earphone charging case assembly, since the second housing is rotatably connected to the first housing, the second housing is formed with a communicating movable groove and a mounting groove, the earphone bracket is located in the movable groove and is movably connected to the second housing, the movable linkage assembly is located in the mounting groove and is movably connected to the second housing, and since one end of the movable linkage assembly is connected to the first housing and the other end of the movable linkage assembly is connected to the earphone bracket, the movable linkage assembly is used to drive the earphone bracket to move relative to the second housing when the first housing and the second housing rotate relative to each other, so as to pick up and place the earphone, improving the picking and placing efficiency of the earphone; the movement of the earphone bracket relative to the second housing is realized by the rotation of the first housing and the second housing, that is, the rotation of the first housing and the second housing drives the earphone bracket to move relative to the second housing so as to pick up and place the earphone. In this way, the picking and placing of the earphone is realized through mechanical linkage, and the overall structure is relatively ingenious. There is no need to use magnets to realize the storage and picking of the earphone, avoiding the problems of a large number of magnets required for the traditional earphone charging case assembly and a large space occupied by the assembly.

[0039] To better understand the technical solutions and beneficial effects of the present application, the following further describes the present application in detail with specific embodiments:

[0040] As Figure 1 And Figure 2a As shown, an earphone device 10 in an embodiment includes an earphone 100 and an earphone charging case assembly 200, and the earphone charging case assembly 200 is used to store the earphone 100. In one embodiment, the earphone charging case assembly 200 includes a first housing 210, a second housing 220, an earphone bracket 230, and a movable linkage assembly 240. The second housing 220 is rotatably connected to the first housing 210. The second housing 220 is formed with a communicating movable groove 202 and a mounting groove 204. The earphone bracket 230 is located in the movable groove 202 and is movably connected to the second housing 220. The earphone bracket 230 is formed with a storage groove 206 for accommodating the earphone 100. The movable linkage assembly 240 is located in the mounting groove 204 and is movably connected to the second housing 220. One end of the movable linkage assembly 240 is connected to the first housing 210, and the other end of the movable linkage assembly 240 is connected to the earphone bracket 230. The movable linkage assembly 240 is used to drive the earphone bracket 230 to move relative to the second housing 220 when the first housing 210 and the second housing 220 rotate relative to each other, so as to pick up and place the earphone 100.

[0041] As Figure 2aAs shown in the figure, when the first housing 210 rotates relative to the second housing 220 in the first direction, at the same time, the first housing 210 drives the earphone bracket 230 to move relative to the second housing 220 to a first predetermined position through the movable linkage assembly 240, so as to take out the earphone 100; Similarly, before placing the earphone 100, the first housing 210 is also rotated relative to the second housing 220 in the first direction, so that the earphone bracket 230 moves relative to the second housing 220 to the first predetermined position. At this time, the first housing 210 is opened relative to the second housing 220, and the earphone charging box assembly is in an open state; As Figure 2b shown in the figure, when the first housing 210 rotates relative to the second housing 220 in the second direction, at the same time, the first housing 210 drives the earphone bracket 230 to move relative to the second housing 220 to a second predetermined position through the movable linkage assembly 240. At this time, the first housing 210 covers the second housing 220, and the earphone charging box assembly is in a closed state, so that the earphone 100 is quickly received in the earphone charging box assembly 200. In this way, through the relative rotation of the first housing 210 and the second housing 220, the first housing 210 drives the earphone bracket 230 to move relative to the second housing 220 to the first predetermined position or the second predetermined position through the movable linkage assembly 240, so as to realize the placement or removal of the earphone 100.

[0042] For the above-mentioned earphone charging box assembly 200, since the second housing 220 is rotatably connected to the first housing 210, the second housing 220 is formed with a communicating movable groove 202 and an installation groove 204. The earphone bracket 230 is located in the movable groove 202 and is movably connected to the second housing 220. The movable linkage assembly 240 is located in the installation groove 204 and is movably connected to the second housing 220. Also, since one end of the movable linkage assembly 240 is connected to the first housing 210 and the other end of the movable linkage assembly 240 is connected to the earphone bracket 230, the movable linkage assembly 240 is used to drive the earphone bracket 230 to move relative to the second housing 220 when the first housing 210 and the second housing 220 rotate relative to each other, so as to take and place the earphone 100, improving the taking and placing efficiency of the earphone 100; The movement of the earphone bracket 230 relative to the second housing 220 is realized by the rotation of the first housing 210 and the second housing 220, that is, the rotation of the first housing 210 and the second housing 220 drives the earphone bracket 230 to move relative to the second housing 220, so as to take and place the earphone 100. In this way, the taking and placing of the earphone 100 is realized through mechanical linkage, and the overall structure is relatively ingenious. There is no need to use magnets to realize the storage and taking of the earphone 100, avoiding the problems of a large number of magnets required for the traditional earphone charging box assembly 200 and a large space occupied by the assembly.

[0043] As Figure 1 with Figure 2aAs shown, in one embodiment, the earphone holder 230 is slidably connected to the second housing 220, enabling the earphone holder 230 to slide relative to the second housing 220 to a first predetermined position or a second predetermined position, and the way of the movable connection between the earphone holder 230 and the second housing 220 is relatively simple. It can be understood that in other embodiments, the earphone holder 230 and the second housing 220 are not limited to a slidable connection. For example, the earphone holder 230 and the second housing 220 can also be rotatably connected.

[0044] As Figure 1 with Figure 2a As shown, in one embodiment, the second housing 220 is formed with a first positioning groove 208, and the first positioning groove 208 communicates with the movable groove 202 and the receiving groove 206 respectively. The first housing 210 is formed with a second positioning groove 209 communicating with the first positioning groove 208, and the first positioning groove 208 and the second positioning groove are used to jointly receive the head of the earphone 100. When the first housing 210 rotates relative to the second housing 220 in a first direction, the first housing 210 drives the earphone holder 230 to move relative to the second housing 220 to a first predetermined position through the movable linkage assembly 240, so that the first housing 210 is completely opened with respect to the second housing 220. At this time, the head of the earphone 100 simultaneously leaves the first positioning groove 208, so that the earphone 100 can be completely taken out of the earphone charging box assembly 200. When the first housing 210 rotates relative to the second housing 220 in a second direction, the first housing 210 drives the earphone holder 230 to move relative to the second housing 220 to a second predetermined position until the second housing 220 covers the first housing 210. At this time, the head of the earphone 100 is simultaneously located in the first positioning groove 208 and the second positioning groove 209, so that the earphone 100 is completely received in the earphone charging box assembly 200.

[0045] As Figure 1 with Figure 2a As shown, further, the earphone holder 230 is slidably limited within the movable groove 202 to prevent excessive sliding of the earphone holder 230 relative to the second housing, so that the earphone holder 230 is slidably connected to the second housing reliably. In this embodiment, a stop groove 202a is formed on the inner wall of the movable groove 202 adjacent to the first positioning groove 208. The stop groove 202a is used to abut against the end of the earphone holder 230 when the receiving groove slides relative to the second housing to the second predetermined position, so that the earphone holder 230 is slidably limited within the stop groove 202a to prevent excessive sliding of the earphone holder 230 relative to the second housing.

[0046] As Figure 2a with Figure 3As shown, in one embodiment, the earphone charging case assembly 200 further includes a rotating member 250. The second housing 220 is formed with a rotation limiting groove 211, and the rotation limiting groove 211 communicates with the movable groove 202. The rotating member 250 is located in the rotation limiting groove 211 and is rotatably connected to the second housing. The rotating member 250 is also rotatably connected to the earphone bracket 230. When the earphone bracket 230 slides relative to the second housing, the earphone bracket 230 simultaneously rotates relative to the rotating member 250. At the same time, the rotating member 250 is rotatably connected to the second housing, enabling the earphone bracket 230 to slide relative to the second housing within a predetermined stroke range, and further enabling the earphone bracket 230 to slide reliably between a first predetermined position and a second predetermined position relative to the second housing, while ensuring that the earphone bracket has good balance when sliding up and down relative to the second housing. And / or, in one embodiment, a slide rail 202b is formed in the movable groove 202, and a sliding groove 232 is formed in the outer peripheral wall of the earphone bracket 230. The slide rail 202b is located in the sliding groove and is slidably connected to the earphone bracket 230, enabling the earphone bracket 230 to slide reliably relative to the second housing along a predetermined direction, and at the same time making the sliding of the earphone bracket 230 relative to the second housing smoother.

[0047] As Figure 2a with Figure 3 As shown, in one embodiment, the movable linkage assembly 240 is an elastic sliding connection assembly, enabling the first housing to drive the earphone bracket 230 to slide relative to the second housing through the movable linkage assembly 240. In one embodiment, the movable linkage assembly 240 includes an elastic sliding block 242 and a connecting member 244. The elastic sliding block 242 is located in the mounting groove 204 and is slidably connected to the second housing 220. The elastic sliding block 242 is connected to the earphone bracket 230, and the connecting member 244 is respectively movably connected to the elastic sliding block 242 and the first housing 210, enabling the elastic sliding block 242 to be movably connected to the first housing 210, so that the second housing 220 drives the earphone bracket 230 to move relative to the second housing 220 through the movable linkage assembly 240.

[0048] As Figure 2a with Figure 3As shown, in one embodiment, the connecting member 244 is rotatably connected to the elastic sliding block 242 and the second shell 220, respectively, so that the elastic sliding block 242 is movably connected to the first shell 210 through the connecting member 244. In this embodiment, the connecting member 244 includes a connecting member body 2442, a first rotating shaft 2444 and a second rotating shaft 2446, the first rotating shaft 2444 and the second rotating shaft 2446 are both connected to the connecting member body 2442, the first rotating shaft 2444 is rotatably connected to the second shell 220, and the second rotating shaft 2446 is rotatably connected to the elastic sliding block 242, so that the connecting member 244 is rotatably connected to the elastic sliding block 242 and the second shell 220, respectively. And / or,

[0049] like Figure 2a and Figure 3 As shown, in one embodiment, the first shell 210 is provided with a protruding structure 212, and the connecting member 244 is formed with a rotation limit abutment groove 244a, and the protruding structure is used to abut against the rotation limit abutment groove 244a when the second shell 220 is rotated to the limit position relative to the first shell 210, so as to limit the relative rotation angle between the first shell and the second shell, avoid excessive relative rotation between the first shell and the second shell, and play a role of rotation limiting.

[0050] like Figure 2a and Figure 3As shown, in one embodiment, the elastic sliding block 242 includes a sliding block 2422 and an elastic member 2424. The sliding block 2422 is located in the installation groove 204 and is slidably connected to the second housing 220. The elastic member 2424 is located in the installation groove 204, and one end of the elastic member 2424 is connected to the sliding block 2422, and the other end of the elastic member 2424 is connected to the second housing. The sliding block 2422 is rotatably connected to the connecting member 244, and the sliding block 2422 is connected to the earphone bracket 230. In this embodiment, one end of the elastic member abuts against the sliding block, and the other end abuts against the second housing. When the first housing 210 rotates relative to the second housing 220 in the first direction, that is, when the earphone charging case assembly is opened, the protruding structure drives the connecting member 244 to move relative to the second housing, and the sliding block 2422 slides relative to the second housing 220. At this time, the elastic member 2424 elastically pushes the sliding block to slide, and at the same time, the sliding block 2422 drives the earphone bracket 230 to slide relative to the second housing until it moves to the second predetermined position; when the first housing 210 rotates relative to the second housing 220 in the second direction, that is, when the earphone charging case assembly is closed, the protruding structure drives the connecting member 244 to move relative to the second housing, and the sliding block 2422 slides relative to the second housing 220. At this time, the sliding block compresses the elastic member 2424 downward, and at the same time, the sliding block 2422 drives the earphone bracket 230 to slide relative to the second housing until it moves to the first predetermined position. Through the elastic force of the elastic member and the interaction of moments, the reliability and practicability of the opening and closing of the earphone charging case assembly are realized.

[0051] Specifically, in one embodiment, when the headphone charging case assembly is opened, that is, when the first housing 210 is opened outwards, the elastic member at the bottom of the second housing 220 has an upward spring force, which pushes the sliding block 2422 to move upwards. The sliding block 2422 drives the connecting member to move upwards. After the connecting member moves a certain angle, it is fixed. When the headphone charging case assembly is closed, the user pushes the first housing 210 downwards with their hand. The first housing 210 drives the connecting member to move downwards. The connecting member drives the sliding block 2422 to move downwards. Since the headphones are placed on the headphone holder 230, the headphones will also be driven to move downwards. When the first housing 210 is pushed by a certain angle, that is, when it is closed, the force of the elastic member at the bottom is decomposed, and a relatively large force acts on the first housing 210 to the left, making the first housing 210 and the second housing 220 fit tightly. When opening and closing the case, due to the change in position, the decomposition of its force is different, that is, the direction of the force acting on the first housing 210 is different. When opening, the direction of the force exerted by the connecting member on the first housing 210 is vertically upward; when the first housing 210 is fully opened, the force exerted by the connecting member on the first housing 210 is horizontally to the left. Thus, there is a certain force when opening and closing the case. An elastic member is additionally provided inside the second housing 220 to provide force for the connecting member, ensuring that the first housing 210 and the second housing 220 have a certain acting force when relatively rotating to the open state and the closed state.

[0052] Further, the elastic member 2424 can be a spiral spring or an elastic rubber part, so that the elastic member 2424 has good elasticity. Further, the connecting member is in a U-shaped shape, so that when the first housing 210 and the second housing 220 relatively rotate to different positions, especially when the headphone charging case assembly is opened or closed, the direction of the force exerted by the connecting member on the first housing 210 is different. In this way, it is ensured that the first housing 210 and the second housing 220 have an acting force when relatively rotating to the open state and the closed state. Even further, the connecting member is a silicone part in a U-shaped shape, so that the connecting member has good elasticity when the first housing 210 and the second housing 220 relatively rotate.

[0053] As Figures 2a to 4 shown, further, the first housing 210 includes a first housing body 210a and a first receiving member 210b. The first housing body 210a covers the first receiving member 210b. A second positioning groove is formed in the first receiving member 210b. The first receiving member 210b is rotatably connected to the second housing 220, so that the first housing 210 is rotatably connected to the second housing 220. It can be understood that the first housing body 210a and the first receiving member 210b can be an integrally formed structure, or can be formed and fixedly connected separately.

[0054] As Figures 2a to 4As shown, further, the second housing 220 includes a second housing body 220a and a second receiving member 220b. The second housing body 220a wraps around the second receiving member 220b. The movable slot 202, the first positioning slot, and the mounting slot 204 are all formed in the second receiving member 220b. The first receiving member 210b is rotatably connected to the second receiving member 220b, so that the first housing 210 is rotatably connected to the second housing 220. Further still, the second receiving member 220b is formed with an opening slot 2202, and the opening slot 2202 communicates with the movable slot 202. The earphone bracket 230 is located in the movable slot 202 and is slidably connected to the second receiving member 220b. The earphone bracket 230 can be assembled or disassembled through the opening slot 2202, so as to facilitate the disassembly and assembly of the earphone bracket 230 or regular maintenance and replacement, improving the convenience of use of the earphone charging box assembly 200. In this embodiment, the rotation limiting slot 211 is formed in the second receiving member 220b.

[0055] As Figures 2a to 4 shown, further, the rotation limiting slot 211 includes a limiting slot main body 211a, a first rotation movable slot 211b, and a second rotation movable slot 211c. The rotating member 250 includes a rotating rod 252, a first bent rod 254, and a second bent rod 256. The two ends of the rotating rod 252 are respectively connected to the first bent rod 254 and the second bent rod 256. The rotating rod 252 is located in the limiting slot main body 211a and is rotatably connected to the second receiving member 220b. The first bent rod 254 is rotatably connected to the earphone bracket 230 through the first rotation movable slot 211b, and the second bent rod 256 is rotatably connected to the earphone bracket 230 through the second rotation movable slot 211c, so that the rotating member 250 is rotatably connected to the second housing 220 and the earphone bracket 230. Also refer to Figure 5, in this embodiment, the earphone bracket 230 is formed with a first rotation avoidance groove 232 and a first pivot connection slot 234 that are connected and communicate with each other. The first bent rod 254 is respectively located in the first rotation avoidance groove 232 and the first pivot connection slot 234, and the first bent rod 254 is snapped into the first pivot connection slot 234 through the opening of the first pivot connection slot 234, so that the first bent rod 254 is rotatably connected to the earphone bracket 230. When the earphone bracket 230 slides relative to the second housing 220, the first bent rod 254 rotates in the first pivot connection slot 234, and the first bent rod 254 rotates relative to the earphone bracket 230 in the first rotation avoidance groove 232, achieving a better rotation avoidance effect. Similarly, the earphone bracket 230 is further formed with a second rotation avoidance groove 236 and a second pivot connection slot 238 that are connected and communicate with each other. The second bent rod 256 is respectively located in the second rotation avoidance groove 236 and the second pivot connection slot 238, and the second bent rod 256 is snapped into the second pivot connection slot 238 through the opening of the second pivot connection slot 238, so that the second bent rod 256 is rotatably connected to the earphone bracket 230. When the earphone bracket 230 slides relative to the second housing 220, the second bent rod 256 rotates in the second pivot connection slot 238, and the second bent rod 256 rotates relative to the earphone bracket 230 in the second rotation avoidance groove 236, achieving a better rotation avoidance effect. Further, the opening width of the first pivot connection slot 234 is smaller than the inner diameter of the first pivot connection slot 234, so that the first bent rod is not easily detached from the first pivot connection slot 234. The opening width of the second pivot connection slot 238 is smaller than the inner diameter of the second pivot connection slot 238, so that the second bent rod is not easily detached from the second pivot connection slot 238. In this embodiment, a first insertion inclined surface 234a is formed at the opening of the first pivot connection slot 234, and a second insertion inclined surface 238a is formed at the opening of the second pivot connection slot 238. The first bent rod 254 is snapped into the first pivot connection slot 234 through the first insertion inclined surface, and the second bent rod 256 is snapped into the second pivot connection slot 238 through the second insertion inclined surface 258a, so that both the first bent rod 254 and the second bent rod 256 can be quickly and reliably snapped into the earphone bracket 230.

[0056] As Figure 2a and Figure 3As shown, in one embodiment, the second housing 220 is provided with a guiding post 222 in the mounting groove 204. The sliding block 2422 is slidably connected to the guiding post 222. The elastic member 2424 is sleeved on the guiding post 222 and connected to the sliding block 2422, making the sliding of the sliding block 2422 relative to the second housing more stable, and at the same time enabling the sliding block 2422 to better drive the earphone bracket 230 to slide relative to the second housing along a predetermined direction; and / or, in one embodiment, the second housing 220 further forms a communication groove 223. The movable groove 202 is communicated with the mounting groove 204 through the communication groove 223. The sliding block 2422 is connected to the earphone bracket 230 through the communication groove 223, making the movable groove 202 communicate with the mounting groove 204, and at the same time enabling the sliding block 2422 to be reliably connected to the earphone bracket 230, and making the structure of the earphone charging box assembly 200 more compact.

[0057] As Figure 2a , Figure 5 , Figure 6 and Figure 7 shown, further, the sliding block 2422 includes a sliding block main body 2421, a rotating portion 2423 and a buckling portion 2425. The sliding block main body 2421 is respectively connected to the rotating portion 2423 and the buckling portion 2425. The sliding block main body 2421 is located in the mounting groove 204. The sliding block main body 2421 is sleeved on the guiding post 222 and slidably connected to the guiding post 222. The sliding block main body 2421 abuts against the end of the elastic member 2424. The rotating portion 2423 is located in the mounting groove 204 and rotatably connected to the connecting member 244, making the sliding block 2422 rotatably connected to the connecting member 244. The buckling portion 2425 is connected to the earphone bracket 230 through the communication groove 223, making the sliding block 2422 connected to the earphone bracket 230. Further, the earphone bracket 230 is formed with a clamping groove 231. The buckling portion 2425 is snapped into the clamping groove 231, making the earphone bracket 230 and the sliding block 2422 quickly snap-connected, improving the assembly efficiency of the connection between the earphone bracket 230 and the sliding block 2422. To make the earphone bracket 230 and the sliding block 2422 reliably snap-connected, further, the end of the buckling portion 2425 away from the sliding block main body 2421 is formed with a buckling head 2427. The buckling head 2427 is snapped into the clamping groove. Further, the clamping groove 231 includes a connected clamping groove opening and a connecting groove. The outer diameter of the buckling head is greater than the inner diameter of the clamping opening. The buckling head is snapped into the connecting groove through the clamping groove opening, and the buckling head is located in the connecting groove and connected to the buckling portion 2425, preventing the buckling head from being difficult to disengage from the earphone bracket after being snapped into the connecting groove, and making the earphone bracket and the sliding block 2422 reliably snap-connected.

[0058] As Figure 6 and Figure 7As shown in the figure, further, a first sliding limiting platform 2042 and a second sliding limiting platform 2044 are formed in the installation groove 204. A sliding limiting opening 2045 is formed between the first sliding limiting platform and the second sliding limiting platform. The rotating part 2423 is connected to the sliding block main body 2421 through the sliding limiting opening, so that the sliding block main body 2421 is reliably limited to the same side of the first sliding limiting platform and the second sliding limiting platform. In this embodiment, the first sliding limiting platform and the second sliding limiting platform are arranged in parallel.

[0059] Compared with the prior art, the present invention has at least the following advantages:

[0060] 1. For the above-mentioned earphone charging box assembly 200, since the second housing 220 is rotatably connected to the first housing 210, the second housing 220 is formed with a communicating activity groove 202 and an installation groove 204. The earphone bracket 230 is located in the activity groove 202 and is movably connected to the second housing 220. The activity linkage assembly 240 is located in the installation groove 204 and is movably connected to the second housing 220. Also, since one end of the activity linkage assembly 240 is connected to the first housing 210 and the other end of the activity linkage assembly 240 is connected to the earphone bracket 230, the activity linkage assembly 240 is used to drive the earphone bracket 230 to move relative to the second housing 220 when the first housing 210 and the second housing 220 rotate relative to each other, so as to facilitate the taking and placing of the earphone 100, improving the taking and placing efficiency of the earphone 100;

[0061] 2. For the above-mentioned earphone charging box assembly 200, the overall structure is relatively ingenious. The movement of the earphone bracket 230 relative to the second housing 220 is realized by the rotation of the first housing 210 and the second housing 220, that is, the rotation of the first housing 210 and the second housing 220 drives the earphone bracket 230 to move relative to the second housing 220, so as to facilitate the taking and placing of the earphone 100. In this way, the taking and placing of the earphone 100 is realized through mechanical linkage, without using magnets to realize the storage and taking of the earphone 100, avoiding the problems that the traditional earphone charging box assembly 200 requires a large number of magnets and the assembly occupies a large space.

[0062] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
