Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to a TWS headphone charging case with a liftable charging case. Background Technology

[0002] Currently, TWS earbuds are popular among users due to their freedom from wires and ease of storage. To improve battery life, TWS earbuds are usually equipped with a charging case, which users can store when not in use. However, most TWS earbud charging cases on the market have only a movable lid; the rest are common fixed designs, making the products somewhat dull and uninteresting. Consumers often find the charging case just sitting aside, a burden, and the convenience of retrieving the earbuds is also limited.

[0003] With the advancement of technology, charging cases for retractable TWS earbuds have gradually emerged.

[0004] Referring to Chinese patent document CN111988691A, a height-adjustable Bluetooth earphone case is disclosed, including a case body for storing the earphones, a lid that can be opened and closed at the opening of the case body, and a charging device disposed inside the case body for charging the earphones. It also includes a lifting device connected to the charging device, which drives the earphones to move up or down. The lifting device includes a motor connected to the charging device, a gearbox connected to the motor and rotating under its action, and a rotating mechanism connected to the gearbox and rotating with the gearbox. During rotation, the rotating mechanism drives the earphones to move up or down. However, the technical problems with this Chinese patent document CN111988691A are: the lifting device requires a motor drive, consuming electricity, and the lifting device requires components such as a gearbox and a rotating mechanism, resulting in a complex structure, cumbersome assembly, and high cost.

[0005] See Chinese patent document CN110798772A, which discloses a wireless earphone charging case and a wireless earphone device, including a case body with a receiving cavity for accommodating wireless earphones. The wall of the receiving cavity is provided with an elastic buckle for engaging with a slot of the wireless earphones or a slot for engaging with an elastic buckle of the wireless earphones. A lifting mechanism is installed inside the case body. The lifting mechanism includes a pushing component extending into the bottom of the receiving cavity. The pushing component is slidably installed inside the case body, and when the lifting mechanism is driven, the pushing component moves upward to push out the wireless earphones. However, the technical problem with the Chinese patent document CN110798772A is that the wireless earphones are raised and lowered independently, which requires changing the structure of the wireless earphones. Specifically, a slot needs to be set on the outer shell of the wireless earphones to achieve a locking engagement with the elastic buckle of the housing. This not only affects the appearance of the wireless earphone shell, but also easily damages the shell of the wireless earphones after prolonged use. In addition, during use, it is necessary to manually press down the button and push down the pushing component to push out the wireless earphones, which is inconvenient to use. The structure of the raising and lowering mechanism includes a pushing component, rack, gears and other transmission components, which is relatively complex, cumbersome to assemble, and costly. Summary of the Invention

The front side of the lower outer shell 1 is provided with a light-transmitting panel 101 corresponding to the light-transmitting holes. The lower inner shell 2 is further equipped with a lower cover magnet 13 inside the upper part of the front seat 203. The cover 300 includes an upper outer shell 14 and an upper inner shell 15. The upper inner shell 15 is installed inside the upper outer shell 14. An upper cover magnet 16 corresponding to the lower cover magnet 13 is installed inside the front end of the upper inner shell 15. The upper cover magnet 16 and the lower cover magnet 13 are magnetically attracted to each other. The main control PCBA circuit board 4 is installed at the lower end of the lower inner shell 2. A USB TYPE-C socket 41 and a control button 42 are installed on the lower side of the main control PCBA circuit board 4. The lower outer shell 1 has an opening corresponding to the USB TYPE-C socket and the control button. The charging compartment 5 is also equipped with a battery compartment 503. A rechargeable battery 17 is installed in the battery compartment 503. The rechargeable battery 17 is electrically connected to the charging PCBA circuit board 8.

[0038] like Figures 9-12 As shown, a Hall magnet 18 is installed at the bottom of the charging compartment cavity 201 of the lower inner shell 2. The charging PCBA circuit board 8 is installed at the bottom of the charging compartment 5. A Hall chip 81 corresponding to the Hall magnet 18 is installed on the lower side of the charging PCBA circuit board 8. The Hall chip 81 and the Hall magnet 18 are magnetically induced to cooperate.

[0039] like Figure 2-Figure 5 , Figure 7 , Figure 9 and Figure 11 As shown, the pressing mechanism 10 includes a pressing arm 102. The front end of the pressing arm 102 is provided with a roller 103. When the cover 300 is closed on the box 100, the roller 103 at the front end of the pressing arm 102 can press against the upper middle part of the charging compartment 5. The upper middle part of the charging compartment 5 is provided with a wear-resistant block 504. The rear end of the pressing arm 102 is integrally connected to a connecting seat 104. The connecting seat 104 is provided with an upper hinge 105. The upper hinge 105 is provided with a torsion spring 106 for opening the cover 300. The upper rear end of the lower inner shell 2 is provided with a lower hinge 205. A rotating shaft 2051 is installed on the lower hinge 205. The rotating shaft 2051 is inserted into the upper hinge 105. The torsion spring 106 is fitted onto the rotating shaft 2051.

[0040] When opening the TWS earphone charging case of this invention, the lid 300 is manually opened, and the upper and lower hinges are spring-loaded to easily flip open. After opening the lid, pressing the positioning button 3 compresses the positioning bead 703, releasing the positioning mechanism 7. The lifting spring 6 inside the lower inner shell 2 is released, pushing the charging case assembly 200 to rise. At this time, the Hall chip 81 of the charging PCBA circuit board 8 of the charging case assembly 200 moves away from the Hall magnet 18, and the TWS earphones 9 are activated after rising, entering Bluetooth connection mode. The earphones can then be used by connecting to a Bluetooth device. When closing the TWS earphone charging case, the roller 103 on the pressing mechanism 10 contacts the wear-resistant block 504 and presses down, causing the charging case assembly 200 to descend together. The lid 300 moves in an arc around the pivot. When pressing the wear-resistant block 504, there is sliding friction with a high coefficient of friction, which is converted into rolling friction by the roller 103, making the closing action smoother. When the lid is closed, the positioning bead 703 engages with the arc-shaped concave surface 2033 of the press rod through hole 2032 to lock the charging case assembly 200, and is magnetically attracted to the lid 300 by the upper lid magnet 16 and the lower lid magnet 13. If the positioning button 3 is pressed when the lid is closed, the charging case assembly 200 will not move because the lifting spring 6 is not strong enough to push the lid to rotate, and the attraction force between the upper lid magnet 16 and the lower lid magnet 13 is also present.

[0041] The above description is merely a preferred embodiment of the present invention. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of the present invention shall fall within the scope of the technical solution of the present invention.
