[0027] The switch mechanism includes a rod groove 11, which is opened inside the charging compartment 1, and a push rod 12 is slidably connected to the inner wall of the rod groove 11, and one end of the push rod 12 extending into the rod groove 11 is fixedly connected to a push rod 13, and the push rod 13 passes through the inner wall of the rod groove 11 and slides to extend into the first groove 4, and one end of the push rod 13 extending into the first groove 4 is hinged with a fixed hook 14 through a torsion spring, and the hook head of the fixed hook 14 can hook the hook rod 10, and the inner wall of the rod groove 11 is fixedly connected to a first spring 15, and the first spring 15 sets the push rod 13 inside, and the first The other end of the spring 15 is fixedly connected to one end of the pressing rod 12, a pressing groove 16 is provided inside the charging bin 1, a pressing plate 17 is slidably connected to the inner wall of the pressing groove 16, and the pressing plate 17 extends to the bottom of the charging slot of the charging bin 1, and a pressing rod 18 is fixedly connected to the top of the pressing plate 17, the pressing rod 18 passes through the pressing groove 16 to the inside of the No. 1 slot 4, and the pressing rod 18 can press the tail of the fixing hook 14, and a second spring 19 is fixedly connected to the bottom of the pressing groove 16, and the other end of the second spring 19 is fixedly connected to the bottom of the pressing plate 17;

[0028] The anti-withdrawal mechanism includes a second bracket 20, which is fixedly connected to the outer wall of the sliding block 6, and the outer wall of the second bracket 20 is rotatably connected to a cam 21, and the top inner wall of the No. 1 groove 4 is symmetrically fixedly connected to a support plate 22, the inner wall of the rod groove 11 is fixedly connected to a first piston cylinder 23, the other end of the first piston cylinder 23 is fixedly connected to the outer wall of the push rod 12, the inner wall of the charging groove of the charging warehouse 1 is fixedly connected to a second piston cylinder 24, and the interior of the first piston cylinder 23 is connected to the interior of the second piston cylinder 24 through a pipeline;

[0029] When the earphone 2 is not in use, the user opens the charging case 1, places the earphone 2 in the charging slot of the charging case 1, and presses downward. After the earphone 2 enters the charging slot of the charging case 1, as the earphone 2 continues to go deeper, the bottom of the earphone 2 will squeeze the pressing plate 17, so that the pressing plate 17 slides downward along the pressing slot 16, and the pressing plate 17 will drive the pressing rod 18 to move downward in the process of sliding downward. In the process of the pressing rod 18 moving downward, the outer wall of the pressing rod 18 will squeeze the tail of the fixing hook 14. Because the fixing hook 14 is hinged to one end of the top rod 13 by a torsion spring, when the bottom of the fixing hook 14 is squeezed by the pressing rod 18, the fixing hook 14 will tilt, because the second spring 19 arranged at the bottom of the pressing plate 17 will be squeezed and retracted by the pressing plate 17 when the pressing plate 17 slides downward, but then it will rebound upward under its own elastic force, pushing the squeezing plate back to its original position, so that the pressing plate is also reset and cannot be pressed against the fixing hook 1 4 is squeezed, so that the fixing hook 14 will reset under the torsion force of the torsion spring, but after the fixing hook 14 is tilted, the hook head of the fixing hook 14 can no longer hook the hook rod 10, because the transmission rod 5 is hinged to the inner wall of the No. 1 groove 4 through the torsion spring, and the fixing hook 14 hooks the hook rod 10, so the transmission rod 5 cannot be twisted, but at this time, after the fixing hook 14 no longer hooks the hook rod 10, the transmission rod 5 will be twisted under the torsion force of the torsion spring, and the transmission rod 5 will drive the sliding block 6 slidably connected thereto to move together during the twisting process, and the sliding block 6 will drive the snap ring 7 to move together, and the snap ring 7 will move together with the silicone pad 8, and the silicone pad 8 will contact the outer wall of the earphone 2 during the movement, so that it is fit and clamped with the outer wall of the earphone 2 through the torsion force of the transmission rod 5, and the silicone pad 8 and the silicone plate 3 have greater viscosity, and can adsorb the outer wall of the earphone 2, so that the silicone pad 8 and the silicone plate 3 clamp the outer wall of the earphone 2 and adsorb it between them, thereby completing the adsorption and fixation of the earphone 2;

[0030] If the force when the earphone 2 is separated from the charging slot of the charging case 1 is large, when the earphone 2 is pulled out of the charging slot of the charging case 1, because the sliding block 6 is slidably connected to the outer wall of the transmission rod 5, the force when the earphone 2 is pulled out of the charging slot of the charging case 1 is large. When the earphone 2 is pulled out, the friction between the outer wall of the earphone 2 and the silicone pad 8 is greater than the friction of the sliding block 6 sliding on the transmission rod 5. The earphone 2 will drive the sliding block 6 to slide upward on the outer wall of the transmission rod 5. However, because the inner wall of the No. 1 slot 4 is fixedly connected with the support plate 22, and the support plate 22 is inclined, when the sliding block 6 moves upward, the sliding block 6 will drive the second bracket 20 to move together, and the second bracket 20 will drive the cam 21 to move together. When the cam 21 moves, the outer ring wall of the cam 21 will contact the outer wall of the support plate 22. The cam 21 moves upward, and the outer wall of the cam 21 rubs against the outer wall of the support plate 22, so that the cam 21 rotates. The distances from different areas of the outer wall of the cam 21 to the center of the circle are different. Therefore, when the cam 21 rotates, the outer wall of the cam 21 that is farther from the center of the circle will gradually contact the outer wall of the support plate 22, so that the cam 21 pushes the second bracket 20 to move in the opposite direction of the support plate 22, that is, the direction of the earphone 2, so that the cam 21 pushes the transmission rod 5, so that the silicone pad 8 is more tightly stuck to the outer wall of the earphone 2 when the cam 21 pushes the transmission rod 5, and the tighter it becomes as the earphone 2 slides upward, so that the earphone 2 cannot be separated from the charging slot of the charging bin 1, and the greater the force of the earphone 2 to separate, the greater the force of the silicone pad 8 to clamp and adsorb it.

[0031] When the user needs to take out the earphone 2, the staff only needs to press the push rod 12 toward the inside of the charging compartment 1 to make the push rod 12 slide along the inner wall of the rod groove 11. During the movement of the push rod 12, the push rod 12 will drive the top rod 13 fixed thereto to move together, and the top rod 13 will drive the fixing hook 14 to move together when moving. As the fixing hook 14 moves, the outer wall of the fixing hook 14 will contact the hook rod 10. As the fixing hook 14 continues to move, the fixing hook 14 will be twisted by the push of the hook rod 10. After the fixing hook 14 passes the hook rod 10, the fixing hook 14 will reset and hook the hook rod 10 under the torsion of its torsion spring. At the same time, the push rod 12 will push the first piston cylinder 23 while sliding, thereby shortening the first piston cylinder 23. During the shortening process, the first piston cylinder 23 will discharge the internal gas into the interior of the second piston cylinder 24 through the pipeline. After entering the interior of the second piston cylinder 24, the gas will push the second piston cylinder 24 to move. The plug cylinder 24 extends, and during the extension process of the second piston cylinder 24, one end of the second piston cylinder 24 will push the outer wall of the second bracket 20, so that the second bracket 20 drives the cam 21 and the sliding block 6 to move downward, so that the cam 21 no longer contacts the support plate 22, so that the transmission rod 5 can be reversed. At this time, the user stops pressing the push rod 12, and the push rod 12 will slide back under the elastic force of the first spring 15. The elastic force of the first spring 15 is much greater than the torsion of the torsion spring on the transmission rod 5, so the push rod 12 will reset under the elastic force of the first spring 15 and drive the push rod 13 to reset and move. When the push rod 13 resets, it will pull the hook rod 10 together through the fixed hook 14 to move, so that the fixed hook 14 pulls the transmission rod 5 to reset and twist, so that after the transmission rod 5 is reset, it drives the silicone pad 8 to reset, so that the silicone pad 8 no longer clamps the outer wall of the earphone 2, so that the earphone 2 can be taken out of the charging case 1.

[0032] like Figure 2 As shown; a positioning ring 25 is fixedly connected to the inner wall of the upper side of the charging slot of the charging bin 1, and the top of the positioning ring 25 is an arc-shaped design;

[0033] The inner wall of the positioning ring 25 is evenly and fixedly connected with a sealing plate 26, and the sealing plate 26 is made of a soft material;

[0034] During use, in order to prevent the insertion position of the earphone 2 from being tilted when the user inserts the earphone 2 into the charging slot of the charging bin 1, causing the bottom of the earphone 2 to hit the top of the rubber plate or the top of the second piston cylinder 24, thereby blocking the earphone 2 and preventing it from being inserted into the charging slot of the charging bin 1, a positioning ring 25 is fixedly connected to the inner wall of the charging slot of the charging bin 1. When the bottom of the earphone 2 is inserted into the charging slot of the charging bin 1, the bottom of the earphone 2 will first contact the top of the positioning ring 25, and the inclined top of the positioning ring 25 will guide the earphone 2, so that the earphone 2 can be accurately inserted into the inside of the fixing ring, and then accurately In order to reach the charging slot of the charging bin 1, and in order to prevent impurities from entering the charging slot of the charging bin 1 during daily use, a sealing plate 26 is evenly fixedly connected to the inner wall of the positioning ring 25, and the sealing plate 26 is made of soft rubber. When the earphone 2 enters and exits the positioning ring 25, the outer wall of the earphone 2 will push the sealing plate 26 to deform it, thereby opening the positioning ring 25, so that the earphone 2 can freely enter and exit the positioning ring 25 to enter and exit the charging slot of the charging bin 1. When the earphone 2 is in the positioning ring 25, the sealing plate 26 will reset under its own elastic force, thereby sealing the positioning ring 25 to prevent impurities from entering.

[0035] like Figure 3 As shown; both ends of the hook rod 10 are rotatably connected to the outer wall of the first bracket 9;

[0036] When in use, the hook rod 10 can rotate on the first bracket 9, so when the fixing hook 14 is twisted and the outer wall of the fixing hook 14 rubs against the hook rod 10, the hook rod 10 can rotate, thereby preventing excessive friction between the fixing hook 14 and the hook rod 10, resulting in mutual wear, causing the hook rod 10 and the fixing hook 14 to be stuck, making it impossible for the fixing hook 14 to detach and hook the hook rod 10.

[0037] like Figures 3 to 5 As shown; the sides of the silicone plate 3 and the silicone pad 8 opposite to each other are both frosted;

[0038] When in use, the opposite sides of the silicone plate 3 and the silicone pad 8 are both frosted, so that when the silicone plate 3 and the silicone pad 8 clamp the earphone 2, the friction force of the silicone plate 3 and the silicone pad 8 clamping and adsorbing the outer wall of the earphone 2 is increased, thereby increasing the clamping and adsorption effect of the silicone pad 8 and the silicone plate 3 on the earphone 2.

[0039] like Figure 3 and Figure 5 As shown; the snap ring 7 and the sliding block 6 are hingedly arranged;

[0040] During use, when the snap ring 7 drives the rubber pad to move to fix the earphone 2, the earphone 2 is pulled upward to drive the sliding block 6 to move upward, and the angle between the snap ring 7 and the sliding block 6 will change. The hinged design of the snap ring 7 and the sliding block 6 allows the snap ring 7 to twist as the sliding block 6 slides up and down, so that the snap ring 7 can always fit the outer wall of the earphone 2. In this way, when the earphone 2 is pulled upward to drive the sliding block 6 to move, the snap ring 7 can also always fit the outer wall of the earphone 2 to clamp and adsorb the earphone 2 to prevent the earphone 2 from falling out of the charging slot of the charging bin 1.

[0041] Working principle of the present invention:

[0042] Refer to the instruction manual Figure 1-5 When the earphone 2 is not in use, the user opens the charging compartment 1, places the earphone 2 in the charging slot of the charging compartment 1, and presses downward. After the earphone 2 enters the charging slot of the charging compartment 1, as the earphone 2 continues to go deeper, the bottom of the earphone 2 will squeeze the pressing plate 17, so that the pressing plate 17 slides downward along the pressing slot 16, and the pressing plate 17 will drive the pressing rod 18 to move downward in the process of sliding downward. In the process of the pressing rod 18 moving downward, the outer wall of the pressing rod 18 will squeeze the tail of the fixing hook 14. Because the fixing hook 14 is hinged to one end of the top rod 13 by a torsion spring, when the bottom of the fixing hook 14 is squeezed by the pressing rod 18, the fixing hook 14 will tilt, because the second spring 19 arranged at the bottom of the pressing plate 17 will be squeezed and retracted by the pressing plate 17 when the pressing plate 17 slides downward, but then it will rebound upward under its own elastic force, pushing the squeezing plate back to its original position, so that the lower pressing plate is also reset and cannot squeeze the fixing hook 14 The fixing hook 14 is pressed, so that the fixing hook 14 will reset under the torsion force of the torsion spring. However, after the fixing hook 14 is tilted, the hook head of the fixing hook 14 can no longer hook the hook rod 10, because the transmission rod 5 is hinged to the inner wall of the No. 1 groove 4 by the torsion spring. The fixing hook 14 hooks the hook rod 10, so the transmission rod 5 cannot be twisted. However, after the fixing hook 14 no longer hooks the hook rod 10, the transmission rod 5 will be twisted under the torsion force of the torsion spring. During the twisting process, the transmission rod 5 will drive the sliding block 6 slidably connected thereto to move together, and the sliding block 6 will drive the snap ring 7 to move together, and the snap ring 7 will move together with the silicone pad 8. The silicone pad 8 will contact the outer wall of the earphone 2 during the movement, so that it is fit and clamped with the outer wall of the earphone 2 through the torsion force of the transmission rod 5, and the silicone pad 8 and the silicone plate 3 have greater viscosity, which can adsorb the outer wall of the earphone 2, so that the silicone pad 8 and the silicone plate 3 clamp the outer wall of the earphone 2 and adsorb it between them, thereby completing the adsorption and fixation of the earphone 2;

[0043] If the force when the earphone 2 is separated from the charging slot of the charging case 1 is large, when the earphone 2 is pulled out of the charging slot of the charging case 1, because the sliding block 6 is slidably connected to the outer wall of the transmission rod 5, the force when the earphone 2 is pulled out of the charging slot of the charging case 1 is large. When the earphone 2 is pulled out, the friction between the outer wall of the earphone 2 and the silicone pad 8 is greater than the friction of the sliding block 6 sliding on the transmission rod 5. The earphone 2 will drive the sliding block 6 to slide upward on the outer wall of the transmission rod 5. However, because the inner wall of the No. 1 slot 4 is fixedly connected with the support plate 22, and the support plate 22 is inclined, when the sliding block 6 moves upward, the sliding block 6 will drive the second bracket 20 to move together, and the second bracket 20 will drive the cam 21 to move together. When the cam 21 moves, the outer ring wall of the cam 21 will contact the outer wall of the support plate 22. The cam 21 moves upward, and the outer wall of the cam 21 rubs against the outer wall of the support plate 22, so that the cam 21 rotates. The distances from different areas of the outer wall of the cam 21 to the center of the circle are different. Therefore, when the cam 21 rotates, the outer wall of the cam 21 that is farther from the center of the circle will gradually contact the outer wall of the support plate 22, so that the cam 21 pushes the second bracket 20 to move in the opposite direction of the support plate 22, that is, the direction of the earphone 2, so that the cam 21 pushes the transmission rod 5, so that the silicone pad 8 is more tightly stuck to the outer wall of the earphone 2 when the cam 21 pushes the transmission rod 5, and the tighter it becomes as the earphone 2 slides upward, so that the earphone 2 cannot be separated from the charging slot of the charging bin 1, and the greater the force of the earphone 2 to separate, the greater the force of the silicone pad 8 to clamp and adsorb it.

[0044] When the user needs to take out the earphone 2, the staff only needs to press the push rod 12 toward the inside of the charging compartment 1 to make the push rod 12 slide along the inner wall of the rod groove 11. During the movement of the push rod 12, the push rod 12 will drive the top rod 13 fixed thereto to move together, and the top rod 13 will drive the fixing hook 14 to move together when moving. As the fixing hook 14 moves, the outer wall of the fixing hook 14 will contact the hook rod 10. As the fixing hook 14 continues to move, the fixing hook 14 will be twisted by the push of the hook rod 10. After the fixing hook 14 passes the hook rod 10, the fixing hook 14 will reset and hook the hook rod 10 under the torsion of its torsion spring. At the same time, the push rod 12 will push the first piston cylinder 23 while sliding, thereby shortening the first piston cylinder 23. During the shortening process, the first piston cylinder 23 will discharge the internal gas into the interior of the second piston cylinder 24 through the pipeline. After entering the interior of the second piston cylinder 24, the gas will push the second piston cylinder 24 to move. The plug cylinder 24 extends, and during the extension process of the second piston cylinder 24, one end of the second piston cylinder 24 will push the outer wall of the second bracket 20, so that the second bracket 20 drives the cam 21 and the sliding block 6 to move downward, so that the cam 21 no longer contacts the support plate 22, so that the transmission rod 5 can be reversed. At this time, the user stops pressing the push rod 12, and the push rod 12 will slide back under the elastic force of the first spring 15. The elastic force of the first spring 15 is much greater than the torsion of the torsion spring on the transmission rod 5, so the push rod 12 will reset under the elastic force of the first spring 15 and drive the push rod 13 to reset and move. When the push rod 13 resets, it will pull the hook rod 10 together through the fixed hook 14 to move, so that the fixed hook 14 pulls the transmission rod 5 to reset and twist, so that after the transmission rod 5 is reset, it drives the silicone pad 8 to reset, so that the silicone pad 8 no longer clamps the outer wall of the earphone 2, so that the earphone 2 can be taken out of the charging case 1.
