[0028] like Figure 1 As shown, the charging storage device proposed in an embodiment of the present invention includes a charging compartment 100, a cover body 200, a cover opening mechanism 300 and a cover locking mechanism. The cover locking mechanism is installed on the charging compartment and can be engaged with and disengaged from the cover opening mechanism 300. When the cover locking mechanism is engaged with the cover opening mechanism 300, the cover body 200 is closed, and when the cover locking mechanism is disengaged from the cover opening mechanism 300, the cover body 200 is opened.

[0029] like Figures 2 to 5As shown, the cover opening mechanism includes a first connecting member 310, a second connecting member 320, a first rotating member 330, a second rotating member 340, and a first torsion spring 350. The first connecting member 310 is fixed in the charging compartment, the second connecting member 320 is fixed to the cover, the first rotating member 330 is rotatably connected to the first connecting member 310, the first rotating member 330 is rotatably connected to the second connecting member 320, the second rotating member 340 is rotatably connected to the first connecting member 310, and the second rotating member 340 is rotatably connected to the second connecting member 320. The first torsion spring 350 is installed between the first connecting member 310 and the first rotating member 330. When the cover locking mechanism is disengaged from the cover opening mechanism, the first torsion spring 350 drives the cover 200 to open. Since the cover locking mechanism is directly driven to rotate by the action of the first torsion spring when it is disengaged from the cover opening mechanism, the cover opening mechanism rotates to drive the cover body to open. The entire cover opening process does not require manual opening of the cover body, so that the cover can be automatically opened by pressing a button, which is convenient for users to open the cover body with one hand, eliminating the complicated operation of holding the charging compartment with one hand and flipping up the cover with the other hand. It is simple and convenient, and enhances the user experience.

[0030] The first torsion spring includes a torsion spring body 351 , a first torsion spring arm 352 extending outward from the torsion spring body 351 , and a second torsion spring arm 353 extending outward from the torsion spring body 351 . The first torsion spring arm 352 abuts against the first connecting member 310 , and the second torsion spring arm 353 abuts against the first rotating member 330 .

[0031] refer to Figure 5 In this embodiment, the first connecting member 310 is provided with a first mounting slot 313. The first torsion spring arm 352 extends into the first mounting slot 313 and abuts against the wall of the first mounting slot 313. The first rotating member 330 is provided with a second mounting slot 333. The second torsion spring arm 353 is positioned within the second mounting slot 333 and abuts against the wall of the second mounting slot 333. When the lid is closed, the rotation of the first rotating member 330 causes the second torsion spring arm 353 to rotate, thereby generating a torsion force in the torsion spring. When the lid locking mechanism is disengaged from the lid opening mechanism, the torsion force of the torsion spring drives the first rotating member 330 to rotate, which in turn drives the lid opening mechanism to rotate, thereby opening the lid.

[0032] refer to Figure 4The first connecting member 310 includes a first connecting plate 311 and first side plates 312 provided on the left and right sides of the first connecting plate 311. A first mounting slot 313 is located on the first connecting plate 311. The first side plate 312 is provided with a first connecting hole 314 and a second connecting hole 315, with the first connecting hole 314 located in front of the second connecting hole 315. The second connecting member 320 includes a second connecting plate 321 and second side plates 322 provided on the left and right sides of the second connecting plate 321. The second side plate 322 is provided with a third connecting hole 323 and a fourth connecting hole 324, with the third connecting hole 323 located in front of the fourth connecting hole 324. The first rotating member 330 is plate-shaped and elongated. A fifth connecting hole 331 is provided at one end of the first rotating member 330, and a sixth connecting hole 332 is provided at the other end of the first rotating member 330. The second rotating member 340 is plate-shaped and has an elongated shape. A seventh connecting hole 341 is defined at one end of the second rotating member 340 , and an eighth connecting hole 342 is defined at the other end of the second rotating member 340 .

[0033] The first connecting member 310, the first rotating member 330, and the first torsion spring 350 are connected by a first pin 370. During installation, the first pin 370 sequentially passes through the first connecting hole 314, the fifth connecting hole 331, and the torsion spring body to link the first connecting member 310, the first rotating member 330, and the first torsion spring 350. The first torsion spring arm is positioned within the first mounting slot 313, and the second torsion spring arm is positioned within the second mounting slot 333. The first rotating member 330 and the second connecting member 320 are connected by a second pin 360. During installation, the second pin 360 sequentially passes through the third connecting hole 323 and the sixth connecting hole 332 to link the first and second rotating members 330 and 320. The second connecting member 320 and the second rotating member 340 are connected by a third pin 380. During installation, the third pin 380 sequentially passes through the fourth connecting hole 324 and the eighth connecting hole 342 to link the second connecting member 320 and the second rotating member 340. The second rotating member 340 is connected to the first connecting member 310 via a fourth pin 390. During installation, the fourth pin 390 passes through the second connecting hole 315 and the seventh connecting hole 341, connecting the second rotating member 340 to the first connecting member 310, thereby forming a four-section balanced semi-automatic hinge structure. Rotation of the second torsion spring arm of the first torsion spring drives the first connecting member 310, which in turn drives the lid opening mechanism to open the lid.

[0034] A groove 316 is provided between the first connecting plate 311 of the first connecting member and the two first side plates 312 , and a silicone member 360 is provided in the groove 316 . The silicone member 360 plays a damping role so that the cover body does not open in a spring-like manner and maintains a balanced opening.

[0035] A U-shaped notch is provided on the second connecting piece, and a magnet is installed in the U-shaped notch.

[0036] like Figure 6 As shown, the cover body includes an outer cover 210 and an inner cover 220. The inner cover 220 is provided with an assembly hole 221, and positioning columns 222 are provided on the left and right sides of the assembly hole 221. The second connecting plate of the second connecting member is placed in the assembly hole 221, and the left and right sides of the second connecting plate are provided with positioning holes 325 that cooperate with the positioning columns 222. The outer cover 210 is fixed on the inner cover 220 to clamp the second connecting plate, thereby fixing the second connecting member to the inner side of the cover body. The entire opening mechanism is not exposed outside the product, making the product more beautiful.

[0037] The charging case includes an outer shell 110 and an inner shell 120 . The inner shell 120 is provided with an installation cavity 121 . The first connecting member is placed in the installation cavity 121 , and the first connecting member is connected to the inner shell 120 by screws 130 .

[0038] like Figure 7 and Figure 9 As shown, the locking mechanism includes a button 400 and a lock 500. The button 400 is movably mounted on the charging compartment 100. A telescopic spring 600 is provided between the button 400 and the outer shell of the charging compartment 100. The telescopic spring 600 facilitates pressing the button 400 and resetting the button 400. The lock 500 is rotatably mounted on the charging compartment 100. A second torsion spring 530 is provided between the lock 500 and the outer shell 110 of the charging compartment. A rotating shaft is provided through the charging compartment 100, the lock 500, and the second torsion spring 530 to connect the three. The second torsion spring 530 is used to reset the lock 500.

[0039] One end of the lock catch 500 is a contact end 520, which contacts the button 400. The other end of the lock catch is provided with a barb 510, and the second connecting member 320 is provided with a slot 325 that mates with the barb 510. Pressing the button 400 downward presses the contact end 520 of the lock catch 500 downward, causing the lock catch 500 to rotate counterclockwise, disengaging the barb 510 from the slot 325. At this point, the cover opening mechanism rotates to open the cover under the action of the first torsion spring. Release the button 400, and the lock catch 500 returns to its original position under the action of the second torsion spring 530.

[0040] The following is combined with Figures 7 to 10 Specifically describe the opening principle of the present invention:

[0041] like Figure 7At this time, the cover is closed, and the first torsion spring generates torque due to rotation, causing the first torsion spring arm 352 to abut against the first connecting member 310, and the second torsion spring arm 353 to abut against the first rotating member 330. When opening the cover, the button 400 is pressed downward, and the button 400 presses the contact end 520 of the lock catch 500 downward, causing the lock catch 500 to rotate counterclockwise, causing the hook 510 to disengage from the slot 325. At this time, due to the torque, the second torsion spring arm 353 pushes the first rotating member 330 to rotate clockwise, thereby driving the second connecting member 320 and the second rotating member 340 to rotate clockwise, thereby opening the cover 200 and becoming Figure 10 During the opening process of the cover, the silicone member 360 acts as a damper to prevent the cover 200 from opening in a catapulting manner and to maintain a balanced opening.

[0042] When closing the cover, manually push the cover 200 to the left, the first rotating member 330 and the second rotating member 340 rotate counterclockwise, and the cover opening mechanism begins to semi-self-lock and close until the hook 510 and the slot 325 are buckled with each other, becoming Figure 7 In the state shown, the first torsion spring generates torsion due to rotation, and the torsion of the first torsion spring also causes the slot 325 to hook with the barb 510, ensuring that the barb 510 and the slot 325 do not separate, thereby achieving the purpose of locking and closing the cover.

[0043] like Figure 11 As shown, the charging case is equipped with a fixing hole 140 for securing the earphones and a magnet 150 for attracting the earphones. When the Bluetooth earphones are inserted into the fixing hole of the charging case, the fixing hole will lock the earphones. The magnet also uses suction to ensure that the conductive posts of the earphones and the charging case have a more complete and stable contact, which prevents the earphones from disconnecting during intense shaking, thus enhancing the user experience.

For example, a feature shown or described as part of one embodiment may be used in another embodiment to yield yet another embodiment. The foregoing are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any equivalent variations made using the present description and accompanying drawings are intended to fall within the scope of the present invention.
