[0070] In industries such as food delivery, riders need to ride on the road, so they need to wear head-mounted devices 300 to protect their safety. However, riders often need to answer or make calls from customers, so they need to wear headphones. Therefore, helmets and safety helmets and other head-mounted devices 300 industries add open headphone modules 200 to the head-mounted devices 300. However, the traditional headphone module 200 and the head-mounted device 300 are integrated devices and cannot be disassembled. Once the head-mounted device 300 or the headphone module 200 is damaged, the entire device will be scrapped. In addition, when the user does not need to use it, there is no way to remove the headphone module 200, which will directly increase the weight of the user's head, thereby increasing the burden of use for the user.

[0071] This application proposes a mounting base 100, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the mounting base 100 is used to connect the earphone module 200 with the head-mounted device 300, and the mounting base 100 includes a first seat unit 110 and a second seat unit 120. The first seat unit 110 is detachably connected to the head-mounted device 300; the second seat unit 120 is connected to the first seat unit 110; wherein, the earphone module 200 includes a main control module 210 and a sound receiving and playback module 220, the first seat unit 110 is detachably connected to the main control module 210, and the second seat unit 120 is detachably connected to the sound receiving and playback module 220.

[0072] It should be noted that the main control module 210 and the sound receiving and playback module 220 of the earphone module 200 can be connected by a soft wire. The main control module 210 is equipped with a long-life battery and control capabilities, and has expansion capabilities, and can add driving records or positioning modules, etc. The sound receiving and playback module 220 is used to play and record sounds.

[0073] Since the main control module 210 is detachably connected to the first seat unit 110, and the sound playback module 220 is detachably connected to the second seat unit 120, when the head-mounted device 300 or the earphone module 200 is damaged, the damaged head-mounted device 300 or the earphone module 200 can be disassembled and replaced, thereby avoiding the entire head-mounted device 300 and the earphone module 200 from being scrapped, thereby saving costs. In addition, under this design, if the earphone module 200 and the head-mounted device 300 have technical upgrades, they can also be directly disassembled to avoid the entire device being scrapped.

[0074] In a scenario where the user does not need to wear the earphone module 200 but only needs the head mounted device 300, the user can directly separate the earphone module 200 and the head mounted device 300, and thus only wear the head mounted device 300 to work, thereby avoiding increasing the weight of the user's head and adding a burden to the user.

[0075] In one embodiment, reference Figure 2 and Figure 3 As shown, the first seat unit 110 and the head mounted device 300 are detachably connected via a snap-fit ​​structure 400, and the snap-fit ​​structure 400 includes a buckle 410 and a bayonet 420, wherein one of the buckle 410 and the bayonet 420 is disposed on the first seat unit 110, and the other is disposed on the head mounted device 300.

[0076] In this embodiment, the head mounted device 300 and the mounting base 100 are detachably connected via a snap-on structure 400, so that the user can drill holes in the original head mounted device 300 and add the mounting base 100 and the earphone module 200, so that the original head mounted device 300 can be directly matched with the mounting base 100 and the earphone module 200. This avoids the need for the user to purchase all the mounting bases 100, the earphone modules 200 and the head mounted device 300. This provides customers with more choices and also reduces the purchase cost of the customers.

[0077] In one embodiment, reference Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the mounting base 100 and the main control module 210 further include a first locking unit 500, which is a protrusion or a groove, the protrusion and the groove are matched with each other, and the first locking unit 500 is extended along the length direction X of the first seat unit 110, one of the protrusion and the groove is arranged on the first seat unit 110, and the other is arranged on the main control module 210.

[0078] In this embodiment, the detachable connection between the main control module 210 and the first seat unit 110 is achieved by designing protrusions and grooves. In addition, the first locking unit 500 is extended along the length direction X of the first seat unit 110. When the user needs to install or remove the two, they only need to move the two relatively along the length direction X of the first seat unit 110, which is convenient and quick.

[0079] For further reference, Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the first seat unit 110 has two positioning plates 111 that are arranged opposite to each other, at least one of the positioning plates 111 is provided with the protrusion or the groove, and a movement space 112 is formed between the two positioning plates 111, the sound playback module 220 is arranged in the movement space 112, and the side wall of the main control module 210 is arranged in contact with the positioning plates 111. It should be noted that the protrusion or groove here can be on both positioning plates 111 at the same time, or only one positioning plate 111 can have a protrusion or a groove. In addition, when there are protrusions or grooves on both positioning plates 111, the two positioning plates 111 can both be protrusions or grooves, or one of them can be a protrusion and the other can be a groove.

[0080] Since the side wall of the main control module 210 is in contact with the positioning plates 111 , the main control module 210 is sandwiched between the two positioning plates 111 , thereby being better fixed and preventing the main control module 210 and the first seat unit 110 from being separated during use.

[0081] In one embodiment, reference Figure 6 , Figure 7 as well as Figure 8 As shown, the mounting base 100 and the main control module 210 further include a second locking unit 600, which is a top ball 610 or a bead groove 620, and the top ball 610 and the bead groove 620 are matched, one of the top ball 610 and the bead groove 620 is located in the first seat unit 110, and the other is set in the main control module 210; there is a movement opening 113 between the two positioning plates 111, and the main control module 210 passes through the movement opening 113 and enters the movement space 112 along the length direction X of the first seat unit 110 to cooperate with the first locking unit 500, and the main control module 210 includes a first position not cooperating with the first seat unit 110 and a second position cooperating with the first seat unit 110; wherein, when the main control module 210 is located in the first position, the top ball 610 is located outside the bead groove 620, and when the main control module 210 is located in the second position, the top ball 610 is located in the bead groove 620.

[0082] The present embodiment is provided with a top bead 610 and a bead groove 620. On the one hand, when the top bead 610 and the bead groove 620 cooperate with each other, it can be determined that the main control module 210 has been properly matched with the first seat unit 110, so the top bead 610 and the bead groove 620 can play a positioning role; on the other hand, when the top bead 610 and the bead groove 620 cooperate with each other, since the top bead 610 and the bead groove 620 are mutually engaged, the main control module 210 and the first seat unit 110 cannot be directly pushed to separate from each other, thereby preventing the main control module 210 and the first seat unit 110 from detaching during use.

[0083] For further reference, Figure 6 , Figure 7 as well as Figure 8 As shown, the mounting base 100 further includes a pressing sheet 630 and a pressing space 640 corresponding to the pressing sheet 630, and the pressing sheet 630 is connected to the second locking unit 600; wherein the pressing sheet 630 can be switched between an assembly position and a pressing position, and when the pressing sheet 630 is located at the assembly position, the top bead 610 is matched with the bead groove 620, and when the pressing sheet 630 is located at the pressing position, the top bead 610 is separated from the bead groove 620, or there is a certain gap between the two, so as to facilitate the separation of the two. Here we can talk about the relationship between the pressing space 640 and the two positions.

[0084] When installing the main control module 210 and the first seat unit 110, the pressing sheet 630 can be pressed into the corresponding pressing space 640 to avoid the pressing sheet 630 blocking the opening, so that the installation module can enter through the opening. When the main control module 210 is moved into place, the pressing sheet 630 is away from the pressing space. At this time, the pressing sheet 630 blocks the opening to avoid the pressing sheet 630 from separating from the opening. At this time, the top bead 610 and the bead groove 620 interfere with each other. When the main control module 210 and the first seat unit 110 need to be disassembled, the pressing sheet 630 can also be pressed into the corresponding pressing space 640, and the pressing sheet 630 is away from the opening, while avoiding or reducing the mutual interference between the top bead 610 and the bead groove 620 and the main control module 210 during separation. This design can avoid or reduce the interference caused by the structure of the top bead 610 and the bead groove 620 while obtaining the positioning of the top bead 610 and the bead groove 620.

[0085] In one embodiment, reference Figure 6 and Figure 7As shown, the mounting base 100 also includes a connecting portion 130, the other end of the connecting portion 130 is connected to the second seat unit 120, and one end of the connecting portion 130 is connected to one of the positioning plates 111 of the first seat unit 110, or, it can also be understood that the positioning plate 111 serves as at least a partial structure of the connecting portion 130.

[0086] In this embodiment, the positioning plate 111 is used as one end of the connecting portion 130 . On the one hand, the two can be integrated into one, thereby saving materials; on the other hand, sufficient thickness can be provided for the positioning plate 111 , thereby enhancing the structural strength of the positioning plate 111 .

[0087] In one embodiment, reference Figure 5 , Figure 6 , Figure 7 as well as Fig. 9 As shown, the mounting base 100 and the sound receiving and playing module 220 further include a third locking unit 700, which is disposed on the second seat unit 120, and is a protrusion or a groove, and the third locking unit 700 is extended along the length direction X of the second seat unit 120. The third locking unit is extended along the length direction X of the second seat unit 120, and when the user needs to install or remove the two, they only need to move the two relatively along the length direction X of the second seat unit 120, which is convenient and quick.

[0088] In one embodiment, reference Figure 5 , Figure 6 , Figure 7 as well as Fig. 9 As shown, the third locking unit 700 has a locking portion 710 and a guiding portion 720 adjacently arranged along the length direction X of the second seat unit 120; when the third locking unit 700 is a protrusion, the locking portion 710 and the guiding portion 720 are protrusions, and the protrusion of the locking portion 710 is larger than the guiding portion 720 along the thickness direction Y; when the third locking unit 700 is a groove, the locking portion 710 and the guiding portion 720 are grooves, and the groove of the locking portion 710 is larger than the guiding portion 720 along the thickness direction Y; the length direction X is perpendicular to the thickness direction Y.

[0089] When the user is installing, the matching position is first confirmed by the guide part 720, and then locked by the locking part 710, so that the second seat unit 120 and the sound receiving and playing module 220 are not easily separated without the action of strong external force. In addition, in this embodiment, the locking part 710 and the guide part 720 are arranged adjacent to each other, so during manufacturing, the locking part 710 and the guide part 720 can be manufactured in one piece, thereby saving manufacturing costs.

[0090] For further reference, Figure 5 , Figure 6 , Figure 7 as well as Fig. 9 As shown, there are multiple third locking units 700 , and the multiple third locking units 700 are located on different surfaces of the second seat unit 120 .

[0091] Since the third locking units 700 are located on different surfaces of the second seat unit 120, when the sound receiving and playback module 220 receives an impact, the plurality of third locking units 700 simultaneously absorb the impact force, thereby preventing the sound receiving and playback module 220 and the second seat unit 120 from being damaged.

[0092] refer to Figure 4 and Figure 5 As shown, the present application also proposes an earphone mounting structure, which includes the mounting base 100 described in any one of the above embodiments. Since the earphone mounting structure has the mounting base 100, the earphone mounting structure also has the functions and advantages of the mounting base 100.

[0093] refer to Figure 1 , Figure 2 as well as Figure 3 A head mounted device 300 is shown, and the head mounted device 300 includes the earphone mounting structure described in the above embodiment. Since the head mounted device 300 has the earphone mounting structure, and the earphone mounting structure includes the mounting base 100, the functions and advantages of the mounting base 100 are also possessed by the head mounted device 300.
