Description

Technical Field

[0001] The utility model relates to the technical field of open earphone charging boxes, in particular to an earphone box. Background Art

[0002] As a charging box for wireless earphones, the earphone box is usually equipped with various buttons such as reset and pairing buttons. The button body on the circuit board is triggered by pressing the button cap. However, pressing the button will cause impact on the button body and the circuit board, especially when the user presses too hard, which can easily cause damage to the button body and the circuit board, shortening the service life of the button.

[0003] In order to solve the above problems, a spring or other elastic member is usually arranged between the key cap and the circuit board to play a role of buffer protection and rebound. The elastic member is usually limited by a limiter or fixed by bonding. For example, in the patent case with authorization announcement number: CN219372561U, the elastic member 63 (spring) is limited by the shaft 62 arranged under the key cap 61. However, in order to allow the spring to have expansion and contraction space, the length of the shaft 62 must be smaller than the length of the spring, which may cause abnormal deformation of the spring and scratch the circuit board. Moreover, since the spring is not directly connected to the key body on the circuit board, when the key is pressed, the spring will still collide with the key body on the circuit board, thereby making noise or even damaging the circuit board.

[0004] However, the elastic part is not easy to replace when it is fixed by bonding, and the glue will affect the elasticity of the elastic part to a certain extent, reducing the protective effect of the elastic part on the key body. As the number of times the key is used increases, the elastic part may fall off and fail to protect the key body. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] Combine the following Figures 1 to 5 The present invention describes an earphone box.

[0036] See also Figures 1 to 5 The embodiment of the utility model provides an earphone box, comprising: a cover body 1 and a box body assembly 2, the box body assembly 2 comprising: a middle shell 21, an electric control module 22, a button cap 23 and an elastic member 24, the rear end of the middle shell 21 is rotatably connected to the rear end of the cover body 1, the middle shell 21 has a button hole penetrating the middle shell 21, and a first profiling groove 211 and a second profiling groove 212 for accommodating a left earphone and a right earphone respectively; the electric control module 22 comprises a circuit board 221 and a trigger button 222 arranged on the circuit board 221, the circuit board 221 is arranged On the side of the middle shell 21 facing away from the cover body 1, the trigger button 222 is arranged toward the button hole; the button cap 23 is at least partially in the button hole; the elastic member 24 is arranged between the button cap 23 and the trigger button 222, the elastic member 24 has a accommodating cavity, and the side of the elastic member 24 facing the trigger button 222 has an opening connected to the accommodating cavity, the trigger button 222 at least partially extends into the accommodating cavity so that the elastic member 24 is sleeved on the trigger button 222, and when the button cap 23 is pressed, the elastic member 24 can be deformed and contact with the trigger button 222.

[0037] Specifically, the cover 1 is rotated relative to the middle shell 21 to open or close the earphone box. The first contoured groove 211 on the middle shell 21 is used to store the left earphone, and the second contoured groove 212 is used to store the right earphone. The trigger button 222 can be a reset pairing button. For example, by pressing the reset pairing button, the earphones (left earphone and right earphone) can enter the pairing state; long pressing the reset pairing button can reset the earphone box and the earphones.

[0038] The end of the key cap 23 away from the elastic member 24 can be convex or recessed on the inner surface of the middle shell 21, or can be flush with the inner surface of the middle shell 21. Preferably, when the key cap 23 is in a natural state (when the key cap 23 is not pressed), the end of the key cap 23 away from the elastic member 24 is flush with the inner surface of the middle shell 21, which can prevent accidental touching of the key cap 23 and is also more aesthetically pleasing.

[0039] Since the elastic member 24 is between the key cap 23 and the trigger key 222, when the key cap 23 is pressed, the key cap 23 will squeeze the elastic member 24, causing the elastic member 24 to deform and contact the trigger key 222, thereby pressing the trigger key 222. The elastic member 24 can protect the trigger key 222 to prevent the trigger key 222 from hard contact with the key cap 23; in addition, the elastic member 24 is also used to drive the key cap 23 to rebound, so that the user has a better key usage experience.

[0040] The elastic member 24 has an opening on one side facing the trigger button 222. By bringing the elastic member 24 close to the trigger button 222, the part of the trigger button 222 close to the button cap 23 can be wrapped in the accommodating cavity of the elastic member 24, so that the installation of the elastic member 24 can be completed quickly. The elastic member 24 is limited by the trigger button 222 itself, which is convenient and reliable, and enables the elastic member 24 to provide 360-degree all-round protection for the trigger button 222 to prevent the trigger button 222 from being damaged. When the elastic member 24 needs to be replaced, it only needs to be moved in a direction away from the trigger button 222 to separate the elastic member 24 from the trigger button 222.

[0041] The earphone box of the present invention arranges an elastic member 24 between the button cap 23 and the trigger button 222, thereby preventing the button cap 23 and the trigger button 222 from making noise or causing damage to the trigger button 222 due to hard contact. The elastic member 24 has a receiving cavity with an opening toward the trigger button 222. The elastic member 24 can be mounted on the trigger button 222 by simply bringing the elastic member 24 close to the trigger button 222 to complete the installation of the elastic member 24. Since the elastic member 24 is wrapped around the outside of the trigger button 222, the elastic member 24 can provide all-round protection for the trigger button 222, thereby effectively solving the problem that the elastic member 24 is inconvenient to replace and the protection effect on the button body is not good.

[0042] See also Figure 5 In some embodiments, a positioning foot 241 and a positioning member 242 are provided at one end of the elastic member 24 facing the trigger button 222, a positioning slot is provided on the trigger button 222, the positioning foot 241 is inserted into the positioning slot, a positioning hole is provided on the circuit board 221, and the positioning member 242 is clamped in the positioning hole.

[0043] Specifically, the number of the positioning legs 241 and the number of the positioning slots are both multiple, and the number of the multiple positioning legs 241 and the multiple positioning slots is equal and one-to-one corresponding. When installing the elastic member 24, the opening of the elastic member 24 is directed toward the trigger button 222, and the positioning legs 241 are aligned one-to-one with the corresponding positioning slots by rotating the elastic member 24. When the positioning legs 241 are aligned one-to-one with the corresponding positioning slots, the positioning member 242 is also aligned with the positioning hole, and then the elastic member 24 is brought close to the trigger button 222. As the trigger button 222 gradually enters the accommodating cavity of the elastic member 24, the positioning legs 241 also gradually enter the corresponding positioning slot. When the positioning legs 241 abut against the bottom of the positioning slot, the positioning member 242 is just stuck in the positioning hole. By setting the positioning legs 241 and the positioning member 242, the positioning installation of the elastic member 24 is quickly completed.

[0044] When the positioning leg 241 is inside the positioning slot, the inner side wall of the positioning slot can limit the positioning leg 241 and the elastic member 24, preventing the elastic member 24 from rotating relative to the trigger button 222. In addition, the bottom wall of the positioning slot can also limit the positioning leg 241 and the elastic member 24. When the positioning leg 241 abuts against the bottom wall of the positioning slot, there is a gap between the end of the trigger button 222 facing the button cap 23 and the inner wall of the accommodating cavity of the elastic member 24 in the natural state (when not squeezed by the button cap 23), preventing the elastic member 24 from accidentally touching the trigger button 222.

[0045] The elastic member 24 is connected to the circuit board 221 through the positioning member 242, so as to fix the elastic member 24 and prevent the elastic member 24 from being separated from the trigger button 222. The connection between the positioning member 242 and the positioning hole is a snap connection, which is convenient for disassembly.

[0046] In other embodiments, a plurality of positioning feet 241 are provided at one end of the elastic member 24 facing the trigger button 222, and there is at least one group of two positioning feet 241 respectively located on opposite sides of the elastic member 24; when the trigger button 222 extends into the accommodating cavity of the elastic member 24, the two positioning feet 241 are respectively located on opposite sides of the trigger button 222; and mutual limitation of the trigger button 222 and the elastic member 24 is achieved by the two relatively arranged positioning feet 241.

[0047] See also Figures 1 to 3 In some embodiments, along the extension direction of the rotation axis of the middle shell 21 relative to the cover body 1, the first profiling groove 211 and the second profiling groove 212 are arranged at intervals, the elastic member 24 is arranged between the first profiling groove 211 and the second profiling groove 212, and the elastic member 24 is arranged adjacent to the front end of the middle shell 21.

[0048] Specifically, by setting the first profiling groove 211 and the second profiling groove 212 at intervals, the left earphone placed in the first profiling groove 211 and the right earphone placed in the second profiling groove 212 do not interfere with each other, thereby preventing the earphones from being damaged. The first profiling groove 211 and the second profiling groove 212 are set at intervals along the extension direction of the rotation axis of the middle shell 21 relative to the cover body 1, so that when the user opens the cover body 1, the first profiling groove 211 is closer to the left half of the user's body, and the second profiling groove 212 is closer to the right half of the user's body, so that the user can quickly distinguish the left earphone from the right earphone.

[0049] In addition, since the first profiling groove 211 and the second profiling groove 212 are arranged at intervals, in order to reasonably utilize the space and make the structure of the earphone box more compact, the elastic member 24, the button cap 23, the trigger button 222 and other components are all arranged between the first profiling groove 211 and the second profiling groove 212. Optionally, the elastic member 24 is arranged adjacent to the front end of the middle shell 21, and the distance between the elastic member 24 and the first profiling groove 211 is equal to the distance between the elastic member 24 and the second profiling groove 212, which is more aesthetically pleasing.

[0050] See also Figures 1 to 4 In some embodiments, the box body assembly 2 further includes: a lower shell 25, a charging connector 26 and a battery. The lower shell 25 is connected to the middle shell 21, and the lower shell 25 is located on the side of the middle shell 21 away from the cover body 1, and a charging socket is provided at the rear end of the lower shell 25; the charging connector 26 is provided at the rear end of the circuit board 221, and the charging connector 26 is arranged toward the charging socket; the battery is provided on a side of the middle shell 21 close to the lower shell 25, and the battery is electrically connected to the circuit board 221.

[0051] Specifically, components such as the battery and the circuit board 221 are located between the middle shell 21 and the lower shell 25 for concealment. The connection method between the middle shell 21 and the lower shell 25 is not specifically limited, and can be specifically snap-fitted for easy disassembly.

[0052] The battery can be disposed between the first contoured groove 211 and the second contoured groove 212, specifically at the rear side of the elastic member 24, i.e., in the middle of the earphone box, so that the center of the earphone box is as much as possible in the middle, and the earphone box can be placed more stably. The battery is a rechargeable battery, and the user can charge the battery through the charging connector 26, and the battery power can be supplied to the earphone or the circuit board 221.

[0053] In some embodiments, the elastic member 24 is made of soft rubber.

[0054] Specifically, the material of the elastic member 24 may be rubber, silicone or thermoplastic elastomer, among which rubber has good elasticity and recovery, and can provide users with a comfortable key experience; silicone has excellent wear resistance and anti-aging properties, and can provide stable pressing force and touch, ensuring long-term use of the keys; thermoplastic elastomer combines the properties of rubber and plastic, has excellent elasticity and durability, can provide excellent key touch and feedback, and has good wear resistance and anti-aging properties.

[0055] See also Figures 4 to 5 In some embodiments, the button cap 23 includes a pressing portion 231, a connecting arm 232 and a fixing portion 233 connected in sequence, the pressing portion 231 is at least partially located in the button hole, and the fixing portion 233 is connected to a side of the middle shell 21 away from the cover body 1.

[0056] Specifically, the fixing portion 233 has a socket, and a plug connector is provided on the side of the middle shell 21 facing away from the cover body 1, and the plug connector can be inserted and snapped into the socket, so that the fixing portion 233 and the plug connector are connected. The connecting arm 232 has a certain toughness, so that when the user presses the pressing portion 231, even if the fixing portion 233 remains stationary, the pressing portion 231 can still move slightly and squeeze the elastic member 24, so that the elastic member 24 contacts the trigger button 222. Among them, the pressing portion 231, the connecting arm 232 and the fixing portion 233 are integrally formed, and the button cap 23 can be a plastic part.

[0057] See also Figure 3 to Figure 4 In some embodiments, the earphone box further includes: a first adsorbent 3 and a second adsorbent 4, the first adsorbent 3 being disposed at the front end of the middle shell 21 on the side facing away from the cover body 1; the cover body 1 has a cavity inside, and the second adsorbent 4 is disposed at the front end of the cavity inside the cover body 1, and when the cover body 1 is in a closed state, the first adsorbent 3 and the second adsorbent 4 are adsorbed on each other.

[0058] Specifically, one of the first adsorbent 3 and the second adsorbent 4 is a magnet, and the other is a metal part that can be adsorbed by a magnet, or both are magnets. When the cover body 1 is in a closed state, the first adsorbent 3 and the second adsorbent 4 are adsorbed against each other so that the cover body 1 remains in a closed state, thereby preventing the earphones from falling out of the earphone box. Specifically, there are two first adsorbents 3, and the second adsorbent 4 is a long strip structure arranged along the extension direction of the axis of rotation of the middle shell 21 relative to the cover body 1. When the cover body 1 is in a closed state, the two first adsorbents 3 are respectively adjacent to the opposite ends of the second adsorbent 4.

[0059] See also Figures 1 to 5In some embodiments, the circuit board 221 has two groups of charging contact pin groups 2211, one group of charging contact pin groups 2211 is inserted into the first contoured groove 211 and is used to charge the left earphone, and the other group of charging contact pin groups 2211 is inserted into the second contoured groove 212 and is used to charge the right earphone; the earphone box also includes two third adsorption members 5, and the third adsorption members 5 are arranged on the side of the middle shell 21 away from the cover body 1, one of the third adsorption members 5 is adjacent to one group of charging contact pin groups 2211 and is used to adsorb the left earphone; the other third adsorption member 5 is adjacent to the other group of charging contact pin groups 2211 and is used to adsorb the right earphone.

[0060] Specifically, the charging contact pin group 2211 includes two charging contact pins, and each of the left earphone and the right earphone has two charging contacts. When the left earphone and the right earphone are placed in the first contoured groove 211 and the second contoured groove 212 respectively, the charging contact pins can contact the charging contacts one by one, thereby charging the left earphone and the right earphone.
