[0057] In order to make the purpose, advantages and features of the present invention clearer, the following is a further detailed description of a mobile terminal with a built-in Bluetooth headset proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following specific implementation methods, the advantages and features of the present invention will be clearer. It should be noted that: the drawings are all in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention; secondly, the structure shown in the drawings is often part of the actual structure.

[0058] Example:

[0059] The structure of a mobile terminal with a built-in Bluetooth headset of the present invention is as follows:

[0060] Combination Figure 1 , Figure 2 As shown, this embodiment includes a mobile terminal body 1, a Bluetooth headset 2, an elastic push unit, a suction unit and a charging unit;

[0061] The mobile terminal body 1 is provided with a receiving cavity 11, which opens at the side of the mobile terminal body 1; the elastic ejection unit is provided at the bottom of the receiving cavity 11, and the Bluetooth headset is provided in the receiving cavity 11 and can freely enter and exit the receiving cavity 11; the elastic ejection unit is a snap-action switch 3, which is immediately stuck when pressed for the first time and is ejected immediately when pressed again;

[0062] Therefore, when using the Bluetooth headset, it is convenient to use and store.

[0063] The attraction unit includes a first magnetic component 31 fixed to the outer end of the button of the quick-action switch 3 and a second magnetic component 22 arranged at the inner end of the Bluetooth headset 2; the first magnetic component 31 and the second magnetic component 22 are magnetically attracted to each other; wherein the first magnetic component 31 is a permanent magnet, and the second magnetic component 22 is an iron product; or the first magnetic component 31 is an iron product, and the second magnetic component 22 is a permanent magnet; or the first magnetic component 31 is a permanent magnet, and the second magnetic component 22 is a permanent magnet; it is sufficient to achieve the attraction of the two to ensure that the Bluetooth headset is not easy to fall off.

[0064] The charging unit includes a charging contact assembly 41 disposed in the accommodating cavity 11 and a charging contact assembly 42 disposed on the Bluetooth headset 2 and matching the charging contact assembly 41. The charging contact assembly 41 is disposed side by side with the first magnetic assembly 31; the charging contact assembly 42 is disposed side by side with the second magnetic assembly 22.

[0065] Therefore, as long as the Bluetooth headset is stored in the accommodating cavity 11, the Bluetooth headset can be charged, that is, as long as the mobile terminal has power, the Bluetooth headset can be charged at any time, so there is no embarrassment of forgetting to charge the Bluetooth headset when using it.

[0066] Usually, a Bluetooth headset must include an earplug, but the earplug is usually irregular in shape, so it is difficult to put the earplug and the headset body into the accommodating cavity 11 at the same time. Therefore, we need to form the Bluetooth headset as a whole into a regular shape so that it can be easily placed. For this purpose, the Bluetooth headset can be designed as the following structure:

[0067] like Figure 3 , Figure 4 As shown, the Bluetooth headset 2 of this embodiment includes an earphone body 21, a retractable earplug 23 arranged on the top surface of the earphone body 21, a second magnetic component 22 and a charging contact component 41 arranged side by side at the inner end of the earphone body 21;

[0068] The earphone body 21 is provided with a stepped hole-shaped earplug slot 24, which can accommodate the retractable earplug 23 in a retracted state;

[0069] A pressure ejection unit connected to the retractable earplug 23 is also provided in the earplug slot 24;

[0070] The pressure ejection unit includes a connecting member 51, a spring 52 whose bottom end is fixed to the bottom surface of the earphone body 21, a hollow rotatable limiting column 53 sleeved on the outside of the spring 52, and an ejection rotating cylinder 54 clamped on the earphone body 21 and sleeved on the outside of the rotatable limiting column 53;

[0071] The connecting piece 51 is a cylinder with two annular grooves evenly arranged on the circumference of the cylinder. One of the annular grooves is used to clamp the bottom of the retractable earplug 23 to realize the rotational connection between the top of the connecting piece 51 and the bottom of the retractable earplug 23, and the other annular groove is used to clamp the top of the rotatable limiting column 53 to realize the rotational connection between the bottom end of the connecting piece 51 and the top of the rotatable limiting column 53; the top of the spring 52 is against the bottom end of the connecting piece 51 or the inner bottom surface of the rotatable limiting column 53; the rotatable limiting column 53 can move toward the bottom and get stuck together with the retractable earplug 23 under the action of external force from the top direction, and then rotate to a fixed angle under the action of external force from the top again and be rebounded by the spring 52.

[0072] like Figure 5 As shown, the rotatable limiting column 53 includes a hollow rotating column 531 and a circular rotating outer edge 532 circumferentially arranged at the bottom end of the rotating column 531; three limiting bosses 533 are evenly distributed circumferentially on the outer side of the rotating outer edge 532; the top surface of the limiting boss 533 is sloped.

[0073] like Figure 7As shown, three limiting grooves 241 are evenly arranged on the inner wall of the small hole of the earplug slot 24, and three limiting bosses 533 extend into the three limiting grooves 241 respectively. A notch 242 is also arranged on the inner wall of the small hole of the earplug slot 24 to make the limiting boss 533 rotate and get stuck. The limiting boss 533 moves up and down in the limiting groove 241; the top of the notch 242 is six evenly distributed slope structures, and the slope structure's hypotenuse abuts against the top surface of the limiting boss 533 during rotation; the notches of the three limiting grooves 241 are respectively located at the bottom of the slope structure. The rotating column 531 is sleeved in the ejection rotating cylinder 54;

[0074] like Figure 6 as well as Fig. 9 As shown, the bottom end of the ejector rotating cylinder 54 is twelve continuous isosceles triangular teeth, and the same side waist of three of the isosceles triangular teeth is adapted to the top surface of the three limiting bosses 533; three protrusions 541 are evenly distributed on the outer circumference of the ejector rotating cylinder 54; the three protrusions 541 are respectively located in the three limiting grooves 241 and move up and down.

[0075] The present invention provides a mobile terminal with a built-in Bluetooth headset, which includes two use processes, which are as follows:

[0076] 1. Storage of Bluetooth headsets:

[0077] First, the retractable earplug 23 is pressed to push the ejector rotating cylinder 54 inwardly. Then, the three protrusions 541 in the three limiting grooves 241 limit the circumferential rotation of the ejector rotating cylinder 54. At the same time, three isosceles triangular teeth on the ejector rotating cylinder 54 interact with the three limiting bosses 533 to push the three limiting bosses 533 to move inwardly. When the slopes on the three limiting bosses 533 move to the slope structure of the notch 242, the three limiting bosses 533 slide down along the inclined edge of the slope structure, and at the same time drive the rotatable limiting column 53 to rotate. When the rotatable limiting column 53 rotates to the next slope structure, it is stuck due to the height difference between the limiting boss 533 and the next slope structure, and the retractable earplug 23 is stored in the large hole of the earplug slot 24. At this time, the Bluetooth headset immediately forms a regular shape that is convenient for storage in the accommodating cavity 11.

[0078] Secondly, put the Bluetooth headset with a regular shape into the accommodating cavity 11. At this time, the first magnetic component 31 fixed on the outer end of the button of the quick-action switch 3 is attracted by the second magnetic component 22. Continue to push the Bluetooth headset inward, and the quick-action switch 3 will be stuck immediately under the action of pressing. At the same time, the charging contact component 41 and the matching charging contact component 42 are docked, and the Bluetooth headset is charged through the mobile terminal.

[0079] Thus, the storage and charging of the Bluetooth headset is achieved.

[0080] 2. How to use Bluetooth headset:

[0081] First, push the side of the Bluetooth headset, then the button of the quick-action switch 3 is pushed, the Bluetooth headset is immediately ejected, and at the same time, the charging contact assembly 41 and the matching charging contact assembly 42 are separated, and the charging is disconnected. At this time, since the first magnetic assembly 31 and the second magnetic assembly 22 fixed on the outer end of the button of the quick-action switch 3 are still in the adsorption state, it is necessary to manually pull out the Bluetooth headset;

[0082] Secondly, after pulling out the Bluetooth headset, pressing the retractable earplug 23, the ejector rotating cylinder 54 also moves inward again, and three of the isosceles triangular teeth on the ejector rotating cylinder 54 interact with the three limiting bosses 533 to push the three limiting bosses 533 to move inward. When the slopes on the three limiting bosses 533 move to the slope structure of the notch 242, the three limiting bosses 533 slide down along the inclined side of the slope structure, and at the same time drive the rotatable limiting column 53 to rotate. When the rotatable limiting column 53 rotates to the bottom of the next slope structure, the three limiting bosses 533 are respectively located at the notches of the three limiting grooves 241. At this time, under the elastic force of the spring 52, the rotatable limiting column 53 pops outward, and the three limiting bosses 533 move outward in the three limiting grooves 241, and the retractable earplug 23 is also popped out, making it easy to take out.

[0083] Both of these use processes can make the operation simple and convenient for users.
