For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. The terms used in this document in the specification of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application.

[0022] See attached Figure 1 -Attached Fig. 9 and attached Fig.12 -Attached Fig. 20, a multi-angle flip cover structure of an earphone bin, used to connect a bin body 1 and a bin cover 2, comprising a linkage block 3 and a lock key 4; the linkage block 3 is rotatably mounted on the top side of the bin body 1, and the linkage block 3 is provided with a connecting rod 35 extending to the outside and fixedly connected to the bin cover 2, so that the bin cover 2 can open or close the bin body 1, and a plurality of tooth grooves 31 are also provided on the linkage block 3; the lock key 4 is rotatably mounted on the top of the bin body 1, and the lock key 4 is damped with the bin body 1, and a latch tooth 41 is provided on the lock key 4, and the latch tooth 41 can be adapted and plugged into the plurality of tooth grooves 31 one by one as the lock key 4 rotates.

[0023] Specifically, as attached Figure 1 -Attached Fig. 9 As shown, under normal circumstances, the lock key 4 is located at the initial position, and the latching tooth 41 is disengaged from the tooth groove 31. At this time, the compartment cover 2 can be normally turned over to complete opening or closing of the cover; As attached Fig.12 -Attached Fig.14 As shown, during the opening process, if it is necessary to fix the bin cover 2 at a specific position, when the bin cover 2 is flipped to a suitable angle, the lock key 4 is pressed to overcome the damping to drive the latch tooth 41 to engage with the matching tooth groove 31. Since the lock key 4 and the bin body 1 have damping, the linkage block 3 can be limited from rotating to ensure that the bin cover 2 stays at the current position.

[0024] As attached Fig.16 -Attached Fig.17 When the lid needs to be closed, the lid 2 is pushed to overcome the damping between the lock key 4 and the bin body 1. During this process, the linkage block 3 rotates to drive the latch tooth 41 to gradually disengage from the tooth groove 31. After the lid 2 completely closes the bin body 1, the latch tooth 41 completely disengages from the tooth groove 31 and releases the restriction of the lock key 4 on the linkage block 3, ensuring that the lid 2 can be opened again.

[0025] It should be noted that in the process of the latch tooth 41 gradually disengaging from the tooth groove 31, the lock key 4 rotates and moves to the initial position. When the latch tooth 41 completely disengages from the tooth groove 31, the lock key 4 can be preset to completely return to the initial position or to be still a certain distance away from the initial position. If the second situation is preset, the user can manually pry the lock key 4 back to the initial position when opening the compartment cover 2 again; when the compartment cover 2 wants to stop at a certain angle again, press the lock key 4 again to drive the latch tooth 41 to engage the tooth groove 31.

[0026] In summary, the present invention designs a linkage block 3 on the bin body 1 to realize the rotatable installation of the bin cover 2, and designs a damping-installed lock key 4 on the bin body 1 so that the lock key 4 can stop after rotation, and imposes restrictions on the linkage block 3 by means of the cooperation between the latch tooth 41 and the tooth groove 31, thereby ensuring that the bin cover 2 can stop at a desired angular position. At the same time, since there is a bite effect between the tooth groove 31 and the latch tooth 41, the structural stability can be improved, so that the bin cover 2 can stop more stably. Compared with the prior art, the present solution can adjust and fix the bin cover 2 at multiple angular positions to meet the playability requirements, thereby effectively improving the user experience.

[0027] See attached Fig.12 -Attached Fig.21 The linkage block 3 is provided with a semicircular surface 30, and a plurality of tooth grooves 31 are arranged on the semicircular surface 30, and the plurality of tooth grooves 31 are arranged in an array tilted in a counterclockwise direction; the latch teeth 41 are tilted in a clockwise direction; under this design, the use steps of this solution are as follows: After flipping open the bin cover 2, press the lock key 4 so that the latch tooth 41 lightly fits the linkage block 3, and then let go when the cover is closed to the position where you want to stop (a total of multiple hovering angle positions are preset). During this process, the latch tooth 41 on the lock key 4 will be driven by the linkage block 3 to the closest preset angle position and plug into and engage with the corresponding tooth groove 31; since the tooth groove 31 is in the opposite direction to the latch tooth 41, and the tooth groove 31 is inclined counterclockwise, the lock key 4 will lock the linkage block 3 in the counterclockwise direction, so that the bin cover 2 cannot be flipped counterclockwise and continue to open the cover; but since the lock key 4 does not completely lock the linkage block 3 in the clockwise direction, but only relies on the damping force to limit the linkage block 3, the bin cover 2 can still be closed if it is pushed with appropriate force.

[0028] Therefore, the coordinated use of the above structure enables the linkage block 3 to have a self-locking effect in the counterclockwise direction. In some special usage scenarios, this design can be used to realize other functions of the product; for example, it is convenient for the user to hold the open compartment cover 2 to show others the items on the compartment body 1.

[0029] See attached Fig.12 -Attached Fig.21 The linkage block 3 is also provided with a guide groove 32 , and the lock key 4 is also provided with a reset rib 42 . The reset rib 42 can correspondingly enter and exit the guide groove 32 as the latch tooth 41 is inserted into or separated from the tooth groove 31 .

[0030] Specifically, when the lock key 4 is in the initial position, the reset rib 42 is located outside the guide groove 32; after the bin cover 2 is flipped counterclockwise, if the lock key 4 is pressed so that the latch tooth 41 is inserted into the meshing tooth groove 31, the reset rib 42 simultaneously enters the guide groove 32 and abuts against the bottom surface of the guide groove 32; when the bin cover 2 is flipped clockwise and the cover is continuously closed, the linkage block 3 rotates synchronously, and during this process, the bottom surface of the guide groove 32 drives the reset rib 42 to move, thereby driving the lock key 4 to gradually reset, until the bin cover 2 completely closes the bin body 1, the latch tooth 41 is completely disengaged from the tooth groove 31, the reset rib 42 is also completely disengaged from the guide groove 32, and the lock key 4 completely returns to the initial position to complete the reset.

[0031] In summary, the coordinated use of the guide groove 32 and the reset rib 42 enables the lock key 4 to have an automatic reset function during the closing process after being pressed, thereby preventing the latching tooth 41 on the lock key 4 from hooking into the tooth groove 31 and hindering the normal opening and closing of the cover, making the normal action of the compartment cover 2 and the multi-angle hovering function of the compartment cover 2 perfectly compatible and non-interfering with each other, thereby improving the stability of the overall structural operation.

[0032] See attached Fig.16 -Attached Fig.21 The bottom surface of the guide groove 32 is arc-shaped and seamlessly transitioned, and the bottom edge of the reset rib 42 is chamfered. This design can reduce the friction between the reset rib 42 and the bottom surface of the guide groove 32, ensuring that the reset rib 42 can slide smoothly along the bottom surface of the guide groove 32, thereby facilitating the automatic reset of the lock key 4.

[0033] See attached Figure 1 -Attached Fig. 9 A first rotating shaft 11 and a second rotating shaft 12 are installed on the top of the warehouse body 1; a first rotating hole 33 is provided on the linkage block 3 and is rotatably connected to the first rotating shaft 11, and a second rotating hole 43 is provided on the lock key 4 and is rotatably connected to the second rotating shaft 12; under this design, the rotational connection between the linkage block 3 and the lock key 4 and the warehouse body 1 can be realized.

[0034] See attached Fig.14 -Attached Fig.19 Regarding the method of setting damping between the lock key 4 and the warehouse body 1, the second rotating shaft 12 and the second rotating hole 43 can be interference fit to provide damping between the lock key 4 and the warehouse body 1; or other damping components can be additionally designed. Since there are various ways to design damping at the connection and it is relatively conventional in the mechanical field, the present invention does not limit this. In order to facilitate the understanding of the scheme and improve the stability of the structure in use, in this embodiment, a spring ejector pin 5 is also included. A limiting hole 44 and a waist groove 45 are provided on the side of the lock key 4. The spring ejector pin 5 is installed in the warehouse body 1, and the ejector head 50 of the elastic ejector pin can enter and exit the limiting hole 44 or the waist groove 45 as the lock key 4 rotates to continuously provide damping.

[0035] Specifically, when the lock key 4 is in the initial position, the top head 50 of the spring ejector 5 is inserted into the limiting hole 44 to provide damping between the lock key 4 and the warehouse body 1; when the lock key 4 is pressed to overcome the damping, the lock key 4 rotates and makes the locking tooth 41 approach the tooth groove 31. At this time, the top head 50 of the spring ejector 5 disengages from the limiting hole 44 and enters the waist groove 45, and the top head 50 abuts against the waist groove 45 to continuously provide damping.

[0036] It should be noted that, when the spring ejector pin 5 is designed to be used in conjunction with the limiting hole 44 and the waist hole, a clearance fit can be adopted between the second rotating shaft 12 and the second rotating hole 43, or an interference fit can continue to be adopted to increase damping, and the present invention does not impose any restriction on this; on the other hand, the spring ejector pin 5 is an existing component, so its specific structure is not elaborated in detail in the present invention.

[0037] See attached Figure 6 and attached Fig.21 A slope 450 is provided inside the waist groove 45 and is inclined upward from the bottom of the waist groove 45 toward the limiting hole 44 . After the ejector head 50 of the elastic ejector enters the waist groove 45 , it continuously abuts against the slope 450 .

[0038] Specifically, in the process of the latch tooth 41 approaching the tooth groove 31, the top 50 of the spring ejector pin 5 is located at the upper end of the slope 450. At this time, the spring ejector pin 5 is in a compressed state to continuously apply pressure to the lock key 4, so that the latch tooth 41 on the lock key 4 can automatically find the nearest hovering angle position and engage with the corresponding tooth groove 31; after the latch tooth 41 is fully engaged with the tooth groove 31, the elastic ejector pin releases energy and recovers, and the top 50 of the elastic ejector pin is fully extended and abuts against the lower end of the slope 450 to provide sufficient damping, so that the latch tooth 41 tightly engages the tooth groove 31.

[0039] Similarly, when the resistance between the spring ejector pin 5 and the ramp 450 is overcome and the bin cover 2 is rotated clockwise, the linkage block 3 drives the lock key 4 to reset, and the ejector head 50 of the elastic ejector pin gradually separates from the ramp 450 to return to the limiting hole 44, so that the lock key 4 can stably stop at the initial position after being reset.

[0040] Therefore, the coordinated use of the slope 450 and the elastic ejector pin enables the lock key 4 to have a spinning tendency, making it easier for the latching tooth 41 to locate and plug into the corresponding tooth groove 31, thereby improving the continuity and stability of the overall structure and reducing the risk of jamming.

[0041] See attached Fig.10 -Attached Fig.13 The present invention also includes a buckle seat 6, which is swingably mounted on the top of the warehouse body 1 and is located on the opposite side of the linkage block 3, and the buckle seat 6 can be folded on the warehouse body 1 or flipped away from the warehouse body 1 to expand.

[0042] Specifically, under normal circumstances, the buckle seat 6 is folded on the compartment body 1 to improve portability; when the compartment cover 2 is opened, the buckle seat 6 can be adjusted to an expanded state, and the buckle seat 6 in the expanded state can be used in conjunction with the compartment cover 2 in the open state to form a triangular structure bracket, which is convenient for supporting a mobile phone; in addition, the user can also adjust the hovering angle of the compartment cover 2 to change the support angle, and then adjust the orientation of the mobile phone screen.

[0043] Therefore, the use of the buckle seat 6 and the compartment cover 2 can expand the use function of this product, so that it can be used as a mobile phone holder with an adjustable function, enriching the use function and improving the use experience.

[0044] See attached Fig.12 -Attached Fig.18 A hidden groove 13 is also provided on the top of the warehouse body 1, and the buckle seat 6 has a first position folded in the hidden groove 13 and a second position expanded to be separated from the hidden groove 13.

[0045] Specifically, under normal circumstances, the buckle seat 6 is located in the first position to avoid obstruction in closing the cover, while also improving the aesthetics and portability; when the buckle seat 6 is flipped to the second position, it can be used as a mobile phone holder.

[0046] See attached Fig. 9 and attached Fig.13 -Attached Fig.15 A first stop 14 and a second stop 15 are provided inside the warehouse body 1, and a third stop 16 is provided in the hidden groove 13 of the warehouse body 1; a first stop 34 is provided on the linkage block 3, and when the warehouse cover 2 is flipped to the maximum angle, the first stop 34 abuts against the first stop 14; a second stop 46 is provided on the lock key 4, and when the lock key 4 is in the initial position, the second stop 46 abuts against the second stop 15; a third stop 61 is provided on the buckle seat 6, and when the buckle seat 6 is in the second position, the third stop 61 abuts against the third stop 16.

[0047] Specifically, the combined use of the first stop 14 and the first baffle 34 can limit the maximum rotation angle of the linkage block 3 when it rotates counterclockwise, thereby preventing the compartment cover 2 from rotating excessively; the combined use of the second stop 15 and the second baffle 46 can limit the maximum angle of the lock key 4 when it rotates counterclockwise, thereby preventing the lock key 4 from rotating excessively and protruding from the top of the compartment body 1; and the combined use of the third stop 16 and the third baffle 61 can limit the maximum swinging angle of the buckle seat 6, and provide support for the buckle seat 6, thereby improving the ability of the buckle seat 6 to carry a mobile phone.

[0048] Furthermore, a groove 17 for placing earphones (not shown in the figure) is formed on the top of the housing 1, and electrodes for charging the earphones (not shown in the figure) are arranged in the groove 17; a receiving cavity 18 for installing a circuit board (not shown in the figure) and a battery (not shown in the figure) is provided inside the housing 1, and the circuit board is electrically connected to the electrodes and the battery, and a charging port (not shown in the figure) is installed on the circuit board that passes through the housing 1 to the outside; under this design, the housing 1 has the functions of accommodating the earphones and charging the earphones, and the battery can also be charged through the charging port; the relevant technology is relatively conventional in this field, so the circuit structure of the relevant components is not further elaborated in the present invention.

[0049] See attached Figure 7 The bin cover 2 includes a cover plate 21 and a fixed frame 22, and the linkage block 3 is installed on the fixed frame 22; the cover plate 21 is made of transparent material, and the fixed frame 22 is installed on the cover plate 21 and covers the inner edge of the cover plate 21 to form a transparent portion 210 on the cover plate 21. This design facilitates users to observe the top of the bin body 1 and improves the overall aesthetics.

[0050] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
