[0002] Wireless Bluetooth headsets include Bluetooth headsets and infrared headsets. Bluetooth headsets apply Bluetooth technology to hands-free headsets, allowing users to be free from annoying wires and easily make calls in various ways.
[0003] When the headset is placed in the charging case for charging, the headset contacts the charging contacts of the power supply connection block by gravity. However, a flat charging case may cause the headset to move in the placement slot. At this time, the headset cannot contact the charging contacts by gravity, resulting in poor charging contact of the headset and unable to charge normally.
[0004] Therefore, it is necessary to invent TWS wireless Bluetooth headsets with stable charging to solve the above problems. Summary of the Invention
[0005] In view of the above problems, the present invention provides TWS wireless Bluetooth headsets with stable charging to solve the problems raised in the above background art.
[0006] To achieve the above object, the present invention provides the following technical solution: TWS wireless Bluetooth headsets with stable charging, including a charging case outer shell, a charging case inner shell, and two headset bodies. The charging case inner shell is inserted into the charging case outer shell. A lid is hinged to the rear side of the charging case outer shell, and the lid is magnetically adsorbed and fixed to the charging case inner shell. Two placement slots are provided in the middle of the charging case inner shell, and a stable mechanism is provided between the charging case inner shell and each of the two placement slots.
[0007] Power supply connection blocks are provided at the bottoms of both of the two placement slots. Wires are provided at the bottoms of the power supply connection blocks. One ends of the two wires are connected to the same external power supply unit.
[0008] Further, the stable mechanism includes a placement slot. A stable block is movably inserted into the placement slot. A corresponding stable groove is provided on one side of the headset body. One end of the stable block is fixedly connected to a first toothed block. A spring is fixedly connected to one side of the first toothed block. One end of the spring is fixedly connected to the inner wall of the placement slot. The bottom of the first toothed block is meshed with a transmission gear. The transmission gear is meshed with a second toothed block on one side. A push frame is fixedly connected to the bottom of the second toothed block. A close contact mechanism is provided between the push frame and the power supply connection block.
[0009] Further, the close - fitting mechanism includes a close - fitting block. The top of the close - fitting block is fixedly connected to the bottom of the power - supply connection block. The bottom of the close - fitting block is fixedly connected with an elastic ring, and the bottom of the elastic ring is fixedly connected to the top of the push - frame.
[0010] Further, a friction layer is provided on the bottom surface of the earphone body. The outer surface of the friction layer is fitted with the bottom surface of the insertion groove, and the outer surface of the friction layer is rough.
[0011] Further, a through - hole is provided in the middle of the first toothed block, and the second toothed block is located at the bottom of the through - hole of the first toothed block.
[0012] Further, the elastic ring is hollow and is made of soft rubber material.
[0013] Further, both the push - frame and the close - fitting block are hollow in the middle, and one end of the wire is movably inserted into the middle of the push - frame and the close - fitting block.
[0014] Further, the two stabilizing mechanisms are symmetrically arranged relative to the middle of the inner shell of the charging bin, and the ends of the two stabilizing blocks are both semi - circular.
[0015] The technical effects and advantages of the present invention:
[0016] 1. By providing a stabilizing mechanism, the present invention can limit and fix the position of the bottom of the earphone body in the insertion groove, thereby preventing the earphone body from moving in the insertion groove and disconnecting the charging contacts of the power - supply connection block. At the same time, the stabilizing mechanism can lift part of the power - supply connection block to keep it in close contact with the earphone body, reducing the probability that the earphone has poor contact due to the charging contacts not being fully contacted when the charging bin is placed flat or tilted, and improving the charging stability of the earphone body.
[0017] 2. By providing a close - fitting mechanism, the present invention can prevent the stabilizing mechanism from excessively squeezing the bottom of the earphone body when driving the power - supply connection block to move. At the same time, the close - fitting mechanism continuously provides an upward thrust to the power - supply connection block, making the power - supply connection block tightly fit with the bottom of the earphone body to avoid the situation of poor contact and inability to charge.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0025] The present invention provides a TWS wireless Bluetooth headset with stable charging, as Figures 1 - 3 shown, including a charging bin outer shell 1, a charging bin inner shell 2, and two headphone main bodies 3. The charging bin inner shell 2 is inserted into the charging bin outer shell 1. A bin cover 4 is hinged to the rear side of the charging bin outer shell 1. The bin cover 4 is magnetically adsorbed and fixed to the charging bin inner shell 2. Two loading grooves 5 are provided in the middle of the charging bin inner shell 2. A stabilizing mechanism is provided between the charging bin inner shell 2 and each of the two loading grooves 5;
[0026] Power supply connection blocks 6 are provided at the bottoms of both of the two loading grooves 5. Wires 7 are provided at the bottoms of the power supply connection blocks 6. One ends of the two wires 7 are connected to the same external power supply part 8.
[0027] When charging the earphone main body 3, place it from the loading slot 5 into the inner shell 2 of the charging case. When the earphone main body 3 is loaded to the bottom of the loading slot 5, the stabilizing mechanism slightly lifts the power supply connection block 6 upward, so that the power supply connection block 6 contacts the charging part of the earphone main body 3 more stably. After the external power supply part 8 is connected to the power supply, the battery in the earphone main body 3 can be charged through the wire 7 and the power supply connection block 6. At the same time, the stabilizing mechanism limits and fixes the earphone main body 3 in the loading slot 5, so that the earphone main body 3 will not move in the loading slot 5, resulting in poor contact and inability to charge.
[0028] As Figures 2 - 3 shown, the stabilizing mechanism includes a placement groove 9. The two stabilizing mechanisms are symmetrically arranged relative to the middle of the inner shell 2 of the charging case. A stabilizing block 10 is movably inserted into the placement groove 9. The ends of the two stabilizing blocks 10 are both semicircularly arranged. A corresponding stabilizing groove 11 is provided on one side of the earphone main body 3. One end of the stabilizing block 10 is fixedly connected to a first toothed block 12. A spring 13 is fixedly connected to one side of the first toothed block 12. One end of the spring 13 is fixedly connected to the inner wall of the placement groove 9. The bottom of the first toothed block 12 is meshed with a transmission gear 14. A second toothed block 15 is meshed with one side of the transmission gear 14. A through hole is provided in the middle of the first toothed block 12. The second toothed block 15 is located at the bottom of the through hole of the first toothed block 12. A push frame 16 is fixedly connected to the bottom of the second toothed block 15. A close-fitting mechanism is provided between the push frame 16 and the power supply connection block 6.
[0029] During the process of loading the earphone main body 3 to the bottom of the loading slot 5, the surface of the earphone main body 3 pushes the stabilizing block 10 so that it shrinks into the placement groove 9. The first toothed block 12 moves accordingly and compresses the spring 13. The movement of the first toothed block 12 drives the transmission gear 14 at the bottom to rotate. The second toothed block 15 drives the push frame 16 to rise accordingly. The second toothed block 15 moves upward from the through hole of the first toothed block 12, and the second toothed block 15 will not be hindered from moving. During the rising process of the push frame 16, the power supply connection block 6 is driven to rise. After the power supply connection block 6 contacts the bottom of the earphone main body 3, the close-fitting mechanism drives the power supply connection block 6 to partially contract. When the stabilizing groove 11 at the bottom of the earphone main body 3 moves to the position of the stabilizing block 10, the spring 13 partially resets and pushes the stabilizing block 10 into the stabilizing groove 11. The stabilizing block 10 matches the stabilizing groove 11 to fix the earphone main body 3 in the loading slot 5. At this time, the stabilizing block 10 only drives the push frame 16 to move a small part, while the close-fitting mechanism still keeps the power supply connection block 6 tightly attached to the bottom of the earphone main body 3.
[0030] The present invention is provided with a stabilizing mechanism, which can limit and fix the bottom position of the earphone main body 3 in the loading groove 5, thereby preventing the earphone main body 3 from moving in the loading groove 5 and disconnecting from the charging contact of the power supply connection block 6. At the same time, the stabilizing mechanism can lift part of the power supply connection block 6 to keep it in close contact with the earphone main body 3, reducing the probability that the charging contacts cannot be fully contacted when the charging case is placed flat or tilted, resulting in poor contact of the earphone, and improving the charging stability of the earphone body.
[0031] As Figures 2 - 3 shown, the close-contact mechanism includes a close-contact block 17. The middle parts of the pushing frame 16 and the close-contact block 17 are both hollow. One section of the wire 7 is movably inserted into the middle parts of the pushing frame 16 and the close-contact block 17. The top of the close-contact block 17 is fixedly connected to the bottom of the power supply connection block 6. The bottom of the close-contact block 17 is fixedly connected with an elastic ring 18. The bottom of the elastic ring 18 is fixedly connected to the top of the pushing frame 16. The elastic ring 18 is hollow and made of soft rubber material.
[0032] During the process of the pushing frame 16 driving the power supply connection block 6 to rise, the power supply connection block 6 contacts the bottom of the earphone main body 3 and is pushed downward relative to it. The close-contact block 17 moves downward accordingly and squeezes the elastic ring 18 to deform. After part of the pushing frame 16 is reset, the elastic ring 18 is still in a compressed state and provides support for the close-contact block 17, so that the power supply connection block 6 is tightly attached to the bottom of the earphone main body 3.
[0033] The present invention is provided with a close-contact mechanism, which can prevent the power supply connection block 6 from excessively squeezing the bottom of the earphone main body 3 when the stabilizing mechanism drives it to move. At the same time, the close-contact mechanism continuously provides an upward thrust for the power supply connection block 6, so that the power supply connection block 6 is tightly attached to the bottom of the earphone main body 3 to maintain close contact, avoiding the situation of poor contact and resulting in inability to charge.
[0034] As Figures 1 - 2 shown, a friction layer 19 is provided on the bottom surface of the earphone main body 3. The outer surface of the friction layer 19 is in contact with the bottom surface of the loading groove 5, and the outer surface of the friction layer 19 is rough.
[0035] When the earphone main body 3 is loaded into the bottom of the loading groove 5, the friction layer 19 contacts and frictions with the bottom surface of the loading groove 5, making the loading of the earphone main body 3 more stable, and the friction force between the friction layer 19 and the bottom surface of the loading groove 5 does not prevent the earphone main body 3 from being taken out.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
