Technical Field
[0001] This invention relates to the field of wireless earphone charging case technology, and in particular to a wireless earphone charging case with a self-locking and self-ejecting adapter after being pressed. Background Technology
[0002] True Wireless Stereo (TWS) technology is based on advancements in chip technology. Technically, it refers to a smartphone connecting to a main earphone, which then wirelessly connects to a secondary earphone via Bluetooth, enabling true wireless separation of the left and right audio channels. The application of TWS technology to Bluetooth earphones has given rise to TWS Bluetooth earphones.
[0003] TWS Bluetooth earbuds work by connecting the phone to the main unit via Bluetooth, and then connecting the main unit to the slave units via Near Field Magnetic Induction (NFMI) technology or the TWS protocol. During operation, music signals from the phone are transmitted to the main unit via Bluetooth, and then transmitted from the main unit to the slave units via NFMI or the TWS protocol, thus enabling the left and right earbuds to receive signals. TWS Bluetooth earbuds are popular among users due to their small size and portability.
[0004] There are two common types of adapters for existing TWS Bluetooth earphones:
[0005] 1. Plug and play: The adapter is often located on the outside of the product and can be directly plugged in or removed by hand.
[0006] II. Selection of Standard Self-Locking Switches: 1) Standard parts have fixed minimum dimensions and cannot be directly used on products with compact stacking and limited space. 2) To be compatible with self-locking switches, they must have their own clips, hooks, and slots, which affects the appearance and aesthetics of the adapter.
[0007] Therefore, in this patent application, the applicant has carefully researched a wireless earphone charging case with a self-locking and self-ejecting adapter after being pressed to solve the above problems. Summary of the Invention
[0008] The present invention addresses the shortcomings of the prior art by providing a wireless earphone charging case with a self-locking and self-ejecting adapter that can be pressed. It forms a magnetic self-locking ejection mechanism, eliminating the need for an external structure to match the self-locking switch, thereby protecting the adapter's appearance and aesthetics, and making it more compact and convenient.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A wireless earphone charging case with a self-locking and self-ejecting adapter after being pressed includes a wireless earphone charging case body and an adapter detachably connected to the wireless earphone charging case body. The adapter includes a plug electrically connected to each other and a wireless communication module with magnetic components.
[0011] The wireless earphone charging case body has a first receiving groove for accommodating the wireless communication module. The first receiving groove is equipped with an elastic element, a pull rod, and a magnetic movable plate for magnetically connecting the magnetic element. The magnetic movable plate has a clearance hole for the plug to pass through. One end of the pull rod is connected to the magnetic movable plate, and the two ends of the elastic element are respectively connected to the inner wall of the first receiving groove and the magnetic movable plate.
[0012] A groove is recessed inward from the inner wall of the first receiving groove, and a second receiving groove is provided for receiving the plug. The inner wall surface of the groove is formed with a self-locking groove, a pop-out groove, and a receiving groove. The end of the receiving groove merges into the beginning of the self-locking groove, the end of the self-locking groove merges into the beginning of the pop-out groove, and the end of the pop-out groove merges into the beginning of the receiving groove. The other end of the pull rod extends into the groove, and the other end of the pull rod is slidably mounted in the self-locking groove, the pop-out groove, and the receiving groove and is limited to the beginning of the self-locking groove or the beginning of the receiving groove.
[0013] When the adapter is inserted into the first receiving slot (by default, the other end of the pull rod hooks onto the beginning of the receiving slot), the wireless communication module is pushed inward by external force. The magnetic component of the wireless communication module first magnetically connects with the magnetic movable plate, and the plug extends into the second receiving slot through the clearance hole. Then, the wireless communication module drives the magnetic movable plate to push inward, and the elastic component is deformed by pressure. At the same time, the other end of the pull rod slides along the receiving slot and merges into the beginning of the self-locking slot, completing the insertion of the adapter.
[0014] When the adapter needs to be removed, push the wireless communication module inward again with external force. After the other end of the lever slides into the beginning of the pop-up slot along the self-locking groove, the magnetic movable plate, together with the wireless communication module, slides along the pop-up slot under the reset force of the elastic element and merges into the beginning of the storage slot. At this time, the adapter can be removed.
[0015] As a preferred embodiment, the inner side of the magnetic movable plate is formed with a protrusion for fitting an elastic element, the length of the elastic element being greater than the length of the protrusion, and part of the elastic element fitting around the protrusion; a third receiving groove for accommodating the elastic element and the protrusion is also recessed from the inner wall of the first receiving groove inward.
[0016] As a preferred embodiment, there are two elastic elements, correspondingly two protrusions, and two third receiving grooves. Each elastic element is sleeved around the periphery of a corresponding protrusion, and each third receiving groove is used to accommodate an elastic element and the protrusion it sleeves.
[0017] As a preferred embodiment, the second receiving tank is located between the two third receiving tanks.
[0018] As a preferred embodiment, the wireless earphone charging case body includes a charging case and an adapter mounting shell. The charging case has an inner cavity, and a through hole for communicating with the inner cavity is opened on the side of the charging case. The adapter mounting shell is installed in the inner cavity. The first receiving groove, the second receiving groove, the recess, the self-locking groove, the pop-out groove, and the insertion groove are all formed on the adapter mounting shell. The first receiving groove is set directly opposite the through hole.
[0019] As a preferred embodiment, the adapter mounting housing is detachably connected to the charging case.
[0020] As a preferred embodiment, the inner cavity is equipped with a circuit board. One of the circuit board and the adapter mounting shell is provided with a positioning post, and the other is provided with a positioning groove. The circuit board and the adapter mounting shell are connected, and the positioning post is adapted to fit into the positioning groove.
[0021] As a preferred embodiment, one end of the pull rod is detachably connected to a magnetically movable plate.
[0022] As a preferred embodiment, the pull rod has a U-shaped structure, which has a connecting part perpendicular to the magnetic movable plate and two hooks integrally connected to both ends of the connecting part. One of the two hooks is connected to the magnetic movable plate, and the other extends into the groove. It is slidably installed in the self-locking groove, the ejection groove and the storage groove and is limited to the beginning of the self-locking groove or the beginning of the storage groove.
[0023] As a preferred embodiment, the inlet trough includes a first inlet trough and a second inlet trough that are connected to each other. The beginning of the first inlet trough is the beginning of the inlet trough, the end of the first inlet trough merges into the beginning of the second inlet trough, and the end of the second inlet trough is the end of the inlet trough.
[0024] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it mainly forms a magnetic self-locking ejection mechanism by the cooperation of elastic elements, pull rods, magnetic movable plates, locking grooves, ejection grooves and insertion grooves. It does not require external structure to match the self-locking switch, thereby protecting the appearance integrity and aesthetics of the adapter, making it smaller and more convenient.
[0025] Secondly, the detachable structure of the adapter mounting shell and the detachable structure of its pull rod make assembly convenient and facilitate subsequent maintenance and replacement.
[0026] Furthermore, the overall structural design is ingenious and reasonable, and the assembly of each part is convenient and robust, ensuring the stability and reliability of the product during use.
