[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0043] The present utility model embodiment provides a Bluetooth headset 1000, such as Figure 1-Figure 3 As shown, the Bluetooth headset 1000 includes a housing 10, an ear wing 20 and an elastic locking assembly 30. The housing 10 includes an inserting portion 11 for inserting into the ear of a user. The inserting portion 11 includes an outer peripheral surface wrapped by the ear, and the outer peripheral surface includes a first direction (such as Figure 2 The insertion portion 11 has an installation cavity 111 inside, and the through-portion 113 is communicated with the installation cavity 111; the ear wing 20 is movably arranged in the installation cavity 111 in a first direction, and the ear wing 20 is at least partially exposed outside the through-portion 113, so that the ear wing 20 can cooperate with the clamping end 112 to limit the installation of the Bluetooth headset 1000, and a connecting structure 21 is provided on the ear wing 20; the elastic locking component 30 is arranged in the installation cavity 111 and connected to the connecting structure 21, and the elastic locking component 30 is configured to store energy and lock the ear wing 20 when it is retracted, and release energy and drive the ear wing 20 to move in a direction away from the installation cavity 111 when it is unlocked.

[0044] The Bluetooth headset 1000 of the present application has better wearing stability, is less likely to fall, and is more suitable for sports scenes.

[0045] Specifically, since the ear wing 20 is protruding from the outer surface of the insertion part 11, and the Bluetooth headset 1000 is mounted on the user's ear by cooperating with the clamping end 112, the friction between the Bluetooth headset 1000 and the ear is enhanced, thereby effectively preventing the Bluetooth headset 1000 from falling. In addition, the ear wing 20 and the clamping end 112 are arranged opposite to each other in the first direction of the insertion part 11. After the Bluetooth headset 1000 is clamped, the clamping end 112 and the ear wing 20 are respectively supported on both sides of the insertion part 11, and the force on the Bluetooth headset 1000 in the ear is more balanced, so that the Bluetooth headset 1000 can be worn on the ear more firmly. In addition, the ear wing 20 can be movably arranged in the installation cavity 111. When the Bluetooth headset 1000 is worn, the ear wing 20 can be adapted and fixed according to the size of the ear, and the Bluetooth headset 1000 has a stronger adaptability.

[0046] In addition, the elastic locking assembly 30 provided in the Bluetooth headset 1000 of the present application can lock its position after the ear wing 20 is retracted, so as to facilitate the storage of the Bluetooth headset 1000, for example, to facilitate its placement in a charging compartment, and also to make the charging compartment more compact.

[0047] The shape of the insertion portion 11 is adapted to the ear so that the insertion portion 11 can fully contact the ear. For example, in the present application, the insertion portion 11 is pea-shaped; the pea-shaped insertion portion 11 is closer to the contour of the external auditory canal, so that the two can contact more fully.

[0048] Furthermore, a sound outlet 114 is provided on the insertion portion 11, and the sound outlet 114 is connected to the outside. An earphone unit 40 is also provided in the insertion portion 11, and the earphone unit 40 is arranged relative to the sound outlet 114. Preferably, the earphone unit 40 is close to the sound outlet 114 to provide a larger installation space for the ear wing 20.

[0049] In the present application, the housing 10 further includes an ear handle 12, which is mounted on a side of the inserting portion 11 away from the sound outlet 114. Through the design of the ear handle, the Bluetooth headset 1000 can be more firmly fixed on the ear, reducing the risk of falling off during exercise. Specifically, the ear handle 12 can provide additional support to make the Bluetooth headset 1000 fit the ear more closely. In this way, the Bluetooth headset 1000 is less likely to fall off or become loose when the user is running, exercising, or doing other strenuous exercise.

[0050] In addition, the ear handle portion 12 can also provide installation space to accommodate batteries, control buttons and microphones, so as to reduce the space occupied by these components in the insertion portion 11 and make it more convenient to arrange the ear wings 20.

[0051] In the present application, there are various configurations of the ear wing 20. Preferably, the side of the ear wing 20 exposed outside the opening 113 has a semi-arc surface, and the semi-arc surface has a smoother outer contour, which makes the user more comfortable when wearing it.

[0052] Reference Figure 3-Figure 5 In one embodiment, the Bluetooth headset 1000 further includes a sliding block 22 connected to the ear wing 20, and the sliding block 22 is movably disposed in the mounting cavity 111; the connecting structure 21 is along the second direction (such as Figure 3 A track groove 221 is provided on the sliding block 22 in the second direction (as shown in the Z direction in FIG), the second direction is perpendicular to the first direction, the track groove 221 includes a first limiting groove 2211, a first guiding groove 2212, a second limiting groove 2213 and a second guiding groove 2214 which are sequentially connected end to end, and the first limiting groove 2211 is located on a side of the second limiting groove 2213 away from the through opening 113.

[0053] The elastic locking assembly 30 includes an elastic member 31 and a hook member 32. The elastic member 31 is installed on a side of the sliding block 22 away from the through opening 113 in the first direction, and the hook member 32 is partially accommodated in the track groove 221. When the elastic member 31 is compressed to store energy, the hook member 32 can enter the second limit groove 2213 from the first limit groove 2211 by using the first guide groove 2212. When the elastic member 31 releases energy, the hook member 32 can enter the first limit groove 2211 from the second limit groove 2213 by using the second guide groove 2214. In this way, the ear wing 20 has an unlocking position and a locking position, and will not move after being in the locked position, and the reliability of the structure is better.

[0054] Specifically, the sliding block 22 is slidably connected to the installation cavity 111, and can be integrally formed or combined with the ear wing 20. The elastic member 31 is a spring, and the elastic member 31 acts on the sliding block 22 and makes the sliding block 22 always have a tendency to move toward the through opening 113. The track groove 221, the hook member 32, and the elastic force of the elastic member 31 can cooperate to limit the moving position of the sliding block 22, thereby limiting the moving position of the ear wing 20. Among them, the setting of the first limiting groove 2211 and the second limiting groove 2213 can better limit the sliding block 22 to keep it in a locked or unlocked position. While the hook member 32 is alternately transferred between the first limiting groove 2211 and the second limiting groove 2213, the first guide groove 2212 and the second guide groove 2214 can limit the hook member 32 while guiding the hook member 32 to move more smoothly to the first limiting groove 2211 or the second limiting groove 2213 along a preset path, so as to avoid the hook member 32 from getting stuck during the sliding process of the track groove 221.

[0055] Reference Figure 4-Figure 5 In one embodiment, the second guide groove 2214 is located in the third direction (eg Figure 4 The hooking member 32 is an elastic hooking member 32, which has a tendency to swing and reset in the third direction; the hooking member 32 can be elastically deformed after being subjected to force, and has elastic recovery ability. Specifically, the original position of the hooking member 32 is on one side of the track groove 221 in the third direction. The hooking member 32 is accommodated in the track groove 221 to store a certain elastic potential energy, so that the hooking member 32 always has a tendency to swing in the third direction. The track groove 221 limits the elastic reset of the hooking member 32. When the hooking member 32 moves to each connection of the track groove 221 in the third direction, it can be transferred from the first guide groove 2212 to the second limiting groove 2213 more quickly by elastic potential energy, or from the second limiting groove 2213 to the second guide groove 2214. This embodiment improves the reliability of the structural function by utilizing the characteristics of the hooking member 32 itself.

[0056] Reference Figure 6Further, the second limiting groove 2213 includes an abutting portion 2213a, a leading section 2213b and a trailing section 2213c, one end of the leading section 2213b is connected to an end of the first guide groove 2212 away from the first limiting groove 2211, the other end of the leading section 2213b extends toward the direction close to the first limiting groove 2211 and the second guiding groove 2214, and is connected to the abutting portion 2213a, one end of the trailing section 2213c is connected to an end of the second guiding groove 2214 away from the first limiting groove 2211, and the trailing section The other end of 2213c extends toward the direction close to the first limiting groove 2211 and the first guiding groove 2212, and is connected with the abutting portion 2213a; the abutting portion 2213a locks the hook holding member 32 in the locked position, and the leading section 2213b and the rear guiding section 2213c are V-shaped, and the abutting portion 2213a is located at the bottom of the V-shape, so that the leading section 2213b and the rear guiding section 2213c can further limit the hook holding member 32, making it difficult to disengage from the abutting portion 2213a, so as to improve the stability of the ear wing 20 when it is in the locked position.

[0057] Similarly, the first limiting groove 2211 includes a connected starting section 2211a and a terminal section 2211b, one end of the starting section 2211a is connected to one end of the first guide groove 2212 away from the second limiting groove 2213, and the other end extends in a direction away from the second limiting groove 2213, one end of the terminal section 2211b is connected to one end of the second guide groove 2214 away from the second limiting groove 2213, and the other end extends in a direction away from the second limiting groove 2213, and the distance between the starting section 2211a and the terminal section 2211b gradually narrows in the direction from the first limiting groove 2211 to the second limiting groove 2213. Specifically, the starting section 2211a and the terminal section 2211b are also V-shaped to better limit the position of the hooking member 32 in the first limiting groove 2211, thereby keeping the unlocking position unchanged.

[0058] Furthermore, in the present embodiment, the leading section 2213 b and the trailing section 2213 c as well as the starting section 2211 a and the ending section 2211 b can all guide the hooking member 32 more accurately, so that the hooking member 32 moves into position.

[0059] Furthermore, the starting section 2211a extends in a direction away from the through opening 113 and protrudes from the ending section 2211b. The protruding portion of the starting section 2211a forms a snap-fitting portion, which has the same function as the abutting portion 2213a and can also better limit the hooking member 32 in the first limiting groove 2211, thereby keeping the sliding block 22 in the unlocked position unchanged.

[0060] By implementing this embodiment, the user can unlock and lock by pressing the ear wing 20, and the user's operation feeling is stronger. In order to better understand the technical effect, the working principle in the unlocking and locking application scenario is illustrated below. The user presses the ear wing 20 to overcome the elastic force of the elastic member 31 to retract and move, and the hook member 32 uses the first guide groove 2212 to enter the leading section 2213b of the second limiting groove 2213 from the first limiting groove 2211, and uses the characteristics of the hook member 32 to slide from the leading section 2213b to the abutment portion 2213a, thereby keeping the ear wing 20 in the locked position. When unlocking is required, the user only needs to press the ear wing 20 again to transfer the hook member 32 to the second guide groove 2214 via the abutment portion 2213a, and then use the elastic member 31 to release energy to return it to the first limiting groove 2211, so that the ear wing 20 is in the unlocked position. It can be seen that the unlocking and locking operations of the Bluetooth headset 1000 are simple and easy to use. The pressing operation allows the user to quickly adjust the state of the ear wing 20, which saves time and greatly improves the efficiency of unlocking and locking.

[0061] It is worth mentioning that when the user presses the ear wing 20 to disengage the locked position, a rebound force is generated due to the compression of the elastic member 31. This rebound force can give the user a rebound tactile feeling, allowing the user to more clearly know that the ear wing 20 has been unlocked, thereby improving the user's experience.

[0062] Reference Figure 7-Figure 8 In one embodiment, the leading section 2213b is located adjacent to the first guide groove 2212 (eg Figure 7 The depth is greater than the position where the first guide groove 2212 is adjacent to the leading section 2213b (as shown in the B position in FIG. Figure 7 The position of the second guide groove 2214 adjacent to the rear guide section 2213c (as shown in the A position in FIG. 1 ); Figure 7 The depth is greater than the position where the rear guide section 2213c is adjacent to the second guide groove 2214 (as shown in the F position in FIG. Figure 7 The position adjacent to the abutment portion 2213a and the leading section 2213b (as shown in the E position in FIG. 1 ) Figure 7 The depth is greater than the position adjacent to the leading section 2213b and the abutting portion 2213a (as shown in the D position in FIG. Figure 7 The depth of the starting segment 2211a and the ending segment 2211b is adjacent to each other (as shown in the C position in FIG. Figure 7 The depth is greater than the position adjacent to the end segment 2211b and the start segment 2211a (as shown in the H position in FIG. Figure 7 Such a configuration can prevent the hooking member 32 from retracting in the track groove 221, so that the hooking member 32 can move unidirectionally along the path of the track groove 221, thereby ensuring the reliability of the structure.

[0063] Specifically, the different depths of the leading section 2213b and the first guide groove 2212, the trailing section 2213c and the second guide groove 2214, the leading section 2213b and the abutment portion 2213a, and the tail section 2211b and the starting section 2211a respectively form steps. By utilizing the blocking surface provided by the height difference formed by the steps, the hook member 32 can be prevented from returning to its original position, thereby further limiting the moving path of the hook member 32 to achieve more accurate position control and operation, thereby avoiding the phenomenon of being unable to lock or unlock.

[0064] Reference Figure 6 In one embodiment, the path length of the starting segment 2211a (eg Figure 6 The ear wing 20 has a length of 2211 mm and a width of 3 mm. The ear wing 20 has a length of 2211 mm and a width of 3 mm. The ear wing 20 has a length of 2211 mm and a width of 3 mm. The ear wing 20 has a length of 2211 mm and a width of 3 mm. The ear wing 20 has a length of 2211 mm and a width of 3 mm.

[0065] In addition, by implementing this embodiment, since the ear wing 20 is pressed to enter the locked state, the hook member 32 needs to pass through the first guide groove 2212 to be placed in the second limit groove 2213, and it still needs a longer stroke to switch to the locked state in the free telescopic state. Preferably, an inclined surface is set in the connection area between the first guide groove 2212 and the starting section 2211a, so that the hook member 32 can only enter the first guide groove 2212 from the starting section 2211a by pressing, further preventing the user from accidentally locking the Bluetooth headset 1000 when wearing it. In summary, the user will not accidentally lock the Bluetooth headset 1000 when wearing it, and the stability of the Bluetooth headset 1000 is better.

[0066] Reference Fig. 9 In one embodiment, the hooking member 32 includes a swinging section 321 and a fixed section 322; the fixed section 322 is fixedly arranged in the installation cavity 111 and is located on the side of the sliding block 22 close to the through opening 113; one end of the swinging section 321 is bent and connected to the fixed section 322, and the other end extends in a direction away from the through opening 113 and is hooked in the track groove 221. With such a configuration, the swinging section 321 has a tendency to move in the third direction, so that it can be smoothly transferred in the track groove 221, so that the ear wing 20 can respond more quickly when switching between unlocking and locking.

[0067] Specifically, the hooking member 32 can be formed by bending in one piece, which is convenient for manufacturing and assembly. One end of the hooking member 32 is hooked on the track groove 221, and cooperates with the elastic force of the elastic member 31 to make the hooking member 32 more closely attached to the groove walls of the first limiting groove 2211 and the second limiting groove 2213. The original position of the swinging section 321 is on the side of the second guide groove 2214 away from the first guide groove 2212 in the third direction. The swinging section 321 is placed in the track groove 221, and the swinging section 321 swings and twists relative to the fixed section 322 to deviate from the original position, so that the swinging section 321 generates elastic reset potential energy. Since the first guide groove 2212, the second limiting groove 2213 and the second guide groove 2214 are arranged in sequence in the third direction, when the limiting member moves to the connection between them in the third direction, it can automatically shift to reduce the situation of unlocking or locking not being in place.

[0068] Reference Fig.10 In one embodiment, a receiving groove 222 is provided on the side of the sliding block 22 away from the through opening 113 in the first direction, and a limiting column 1111 is provided on the cavity wall of the installation cavity 111. The limiting column 1111 is extended toward the notch of the receiving groove 222. One end of the elastic member 31 is received in the receiving groove 222, and the other end is sleeved on the limiting column 1111. The limiting column 1111 cooperates with the receiving groove 222 to limit the installation of the elastic member 31 and prevent the elastic member 31 from being twisted under pressure. Specifically, the elastic member 31 is a spring, and the outer contour of the receiving groove 222 can be adapted to the outer ring of the spring, and the outer contour of the limiting column 1111 can be adapted to the inner ring of the spring to improve the limiting effect on the spring.

[0069] Refer again Fig.10 In one embodiment, a guide block 223 is convexly provided on the side of the sliding block 22 facing away from the track groove 221, and a guide groove 1112 is provided on the cavity wall of the installation cavity 111.
