When the second cover body 32 is fully opened, the fifth limiting block 37 abuts against the second limiting surface, thereby limiting the movement of the second cover body 32 to prevent the second cover body 32 from being overly opened or falling off the box body 1.

[0062] The locking mechanism includes a positioning member 7, which can be movably arranged on the earphone bracket 2 up and down, and a first clamping portion 71 is arranged on the top of the positioning member 7, and a second clamping portion 33 is arranged on the inner bottom of the first cover 31 and the second cover 32 respectively; when the box cover 3 is in a closed state, the first clamping portion 71 can be clamped with the corresponding second clamping portion 33, so as to achieve the locking of the first cover 31 and the second cover 32. Specifically, the positioning member 7 of this embodiment is plate-shaped, the first clamping portion 71 is two positioning columns arranged on the top of the positioning member 7, and the second clamping portion 33 is a positioning groove. The first cover 31 and the second cover 32 are locked by the clamping cooperation between the two positioning columns and the two positioning grooves. Further, the end of the above-mentioned positioning column is an arc surface, and the positioning groove is an arc groove. Such a setting can make it easier for the positioning column to slide into the positioning groove, thereby improving the smoothness of the mechanism operation. It should be noted that in other embodiments, the first clamping portion 71 and the second clamping portion 33 can also be set to other structures, which are not limited to this embodiment.

[0063] The unlocking mechanism includes a fixing rod 8, a driving rod, a transmission member and a reset member. The fixing rod 8 is fixed to the bottom of the box body 1. The driving rod is arranged through the side wall of the box body 1 and connected to the fixing rod 8. The transmission member is connected between the driving rod and the positioning member 7. By pushing the driving rod or rotating the driving rod, the positioning member 7 can be driven to move downward so that the first clamping portion 71 and the second clamping portion 33 are disengaged. At this time, the first cover 31 is opened outward under the action of the first elastic member 5, and the second cover 32 is opened outward under the action of the second elastic member 6, thereby realizing the automatic opening process of the Bluetooth headset box. The reset member is arranged in the box body 1. When the box cover 3 is opened, the driving rod is released, and the reset member can restore the driving rod and the positioning member 7 to their original positions.

[0064] refer to Figure 9 and Figure 10 The specific structure of the unlocking mechanism of this embodiment is as follows: the driving rod is a rotating rod 101, the rotating rod 101 extends along the first direction, the first end of the rotating rod 101 is rotatably arranged on the side wall of the box body 1, and the second end of the rotating rod 101 is rotatably connected to the fixed rod 8, so as to realize the rotation of the rotating rod 101. Preferably, a knob 107 is provided at the first end of the rotating rod 101 to facilitate the user to perform a screwing operation. The transmission member includes a connecting block 102 and a first swing rod 103, the connecting block 102 is fixed on the rotating rod 101, the lower end of the first swing rod 103 is hinged to the connecting block 102, and the upper end of the first swing rod 103 is hinged to the lower end of the positioning member 7. In this way, when the rotating rod 101 is rotated, the connecting block 102 can be driven to rotate, the connecting block 102 drives the first swing rod 103 to rotate, and the first swing rod 103 pulls the positioning member 7 to move downward to realize the unlocking of the first cover body 31 and the second cover body 32.

[0065] Further, a first limiting block 104 is provided on the part of the positioning member 7 above the earphone bracket 2. The reset member is a third elastic member 105, and the third elastic member 105 is elastically connected between the first limiting block 104 and the earphone bracket 2. The third elastic member 105 has a tendency to move the positioning member 7 upward. In this embodiment, the first limiting block 104 can limit the rotation angle of the rotating rod 101, avoiding excessive compression of the third elastic member 105 due to too large a rotation angle, and preventing extreme movement of the first swing rod 103 and resulting in damage. Optionally, the third elastic member 105 is a compression spring. When the rotating rod 101 drives the positioning member 7 to move downward, the third elastic member 105 is compressed by the force. When the rotating rod 101 is released, the third elastic member 105 moves the positioning member 7 upward to reset, and at the same time, the positioning member 7 drives the rotating rod 101 to reset through the first swing rod 103. Preferably, an installation groove is provided on the earphone bracket 2 of this embodiment, and the lower end of the third elastic member 105 is installed in the installation groove, and the upper end of the third elastic member 105 is connected to the first limiting block 104. Further, a second limiting block 106 is provided on one side of the positioning member 7 below the earphone bracket 2, which is used to limit the upward movement position of the positioning member 7, so as to prevent the positioning member 7 from being displaced in the height direction under the action of the third elastic member 105 and affecting the closing of the box cover 3.

[0066] The working principle of the Bluetooth headset box provided in this embodiment is as follows:

[0067] When it is necessary to switch the box cover 3 from the closed state to the open state, manually twist the knob 107 to rotate the rotating rod 101. The rotating rod 101 drives the connecting block 102 thereon to rotate, the connecting block 102 drives the first swing rod 103 to rotate, and the first swing rod 103 drives the positioning member 7 to move downward. The first engaging portion 71 is disengaged from the second engaging portion 33 to release the locking of the first cover body 31 and the second cover body 32. At this time, the first cover body 31 and the second cover body 32 move away from each other under the action of the first elastic member 5 and the second elastic member 6, so as to realize the automatic opening of the box cover 3. Then, under the action of the third elastic member 105, the positioning member 7 moves upward and automatically returns to its original position, and at the same time, the positioning member 7 drives the rotating rod 101 to rotate in the reverse direction and automatically return to its original position;

[0068] When it is necessary to switch the box cover 3 from the open state to the closed state, manually clamp the first cover body 31 and the second cover body 32. The first cover body 31 overcomes the acting force of the first elastic member 5, and the second cover body 32 overcomes the acting force of the second elastic member 6. The two move closer to each other. When the first cover body 31 and the second cover body 32 move to the closed position, the second engaging portion 33 is engaged with the first engaging portion 71, and the positioning member 7 keeps the first engaging portion 71 and the second engaging portion 33 in the engaged state under the action of the third elastic member 105, so as to realize the locking of the positions of the first cover body 31 and the second cover body 32.

[0069] The Bluetooth headset case of this embodiment has a compact structure, is small and portable, and has a simple opening method, improving the convenience and practicality of operation, meeting users' pursuit of product innovation and personalization, and bringing a better user experience.

[0075] The working principle of the Bluetooth headset box provided in this embodiment is as follows:

[0076] When it is necessary to switch the lid 3 from the closed state to the open state, the first push rod 201 is pushed into the box body 1. The first push rod 201 drives the pull rope 202 to move, and the pull rope 202 pulls the positioning member 7 to move downward, and the first engaging portion 71 is disengaged from the second engaging portion 33 to release the locking of the first lid body 31 and the second lid body 32; at this time, the first lid body 31 and the second lid body 32 move away from each other under the action of the first elastic member 5 and the second elastic member 6, so as to realize the automatic opening of the lid 3; then, under the action of the fourth elastic member 207, the positioning member 7 moves upward and automatically returns to its original position, and under the action of the fifth elastic member 208, the first push rod 201 moves toward the outside of the box body 1 and automatically returns to its original position;

[0077] When it is necessary to switch the lid 3 from the open state to the closed state, the first lid body 31 and the second lid body 32 are manually clamped. The first lid body 31 overcomes the acting force of the first elastic member 5, and the second lid body 32 overcomes the acting force of the second elastic member 6, and the two move toward each other; when the first lid body 31 and the second lid body 32 move to the closed position, the second engaging portion 33 is engaged with the first engaging portion 71, and the positioning member 7 keeps the first engaging portion 71 and the second engaging portion 33 in the engaged state under the action of the fourth elastic member 207, so as to realize the locking of the positions of the first lid body 31 and the second lid body 32.

[0078] The Bluetooth headset box of this embodiment has a compact structure, is small and portable, and has a simple opening method, improving the convenience and practicality of operation, meeting the user's pursuit of product innovation and personalization, and bringing a better use experience to the user.

[0080] As Figure 3 - Figure 8 and Figure 13 - Figure 14 shown, this embodiment provides a Bluetooth headset box, including a box body 1, a headset bracket 2, a lid 3, an opening mechanism, a locking mechanism, and an unlocking mechanism. The main difference between the Bluetooth headset box provided in this embodiment and that in Embodiment I lies in the different unlocking mechanisms. The same structures as those in Embodiment I will not be described in detail herein.

[0081] refer to Figure 13 and Figure 14 The specific structure of the unlocking mechanism of this embodiment is as follows: the driving rod is the second push rod 301, and the transmission member is the second swing rod 302. The second push rod 301 extends along the second direction, the first end of the second push rod 301 is slidably penetrated through the side wall of the box body 1, the second end of the second push rod 301 passes through the fixed rod 8 and is provided with a blocking block 303, and the blocking block 303 can limit the maximum stroke of the second push rod 301 moving to the outside of the box body 1. The lower end of the second swing rod 302 is hinged to the blocking block 303, and the upper end of the second swing rod 302 is hinged to the lower end of the positioning member 7. The operator pushes the second push rod 301 into the box body 1, which can drive the second swing rod 302 to rotate, and the second swing rod 302 drives the positioning member 7 to move downward, thereby realizing the unlocking of the first cover body 31 and the second cover body 32. Optionally, the first end of the second swing rod 302 is also provided with a button to facilitate the user to perform a pressing operation.

[0082] Furthermore, a limiting ring 304 is provided on the second push rod 301, and the limiting ring 304 is located on the side of the fixed rod 8 away from the blocking block 303; the reset member is a sixth elastic member 305, and the sixth elastic member 305 is provided on the second push rod 301 and is located between the limiting ring 304 and the fixed rod 8, and the sixth elastic member 305 has a tendency to make the second push rod 301 move to the outside of the box body 1. Optionally, the sixth elastic member 305 is a compression spring. When the second push rod 301 is pushed into the box body 1, the sixth elastic member 305 is compressed by force, and when the second push rod 301 is released, the sixth elastic member 305 can make the second push rod 301 move to the outside of the box body 1 and reset; at the same time, the second push rod 301 drives the positioning member 7 to move upward and reset through the second swing rod 302.

[0083] Furthermore, the lower end of the second swing rod 302 is provided with an arc-shaped abutting surface, and the blocking block 303 is also provided with an arc-shaped abutting surface, and the two are abutted through the arc-shaped abutting surface. At the same time, the upper end of the second swing rod 302 is also provided with an arc-shaped abutting surface, and the lower end of the positioning member 7 is provided with an arc-shaped abutting surface, and the two are abutted through the arc-shaped abutting surface. The provision of the above-mentioned arc-shaped abutting surface improves the stability of the second swing rod 302 when swinging, and ensures the reliability of the operation of the mechanism.

[0084] The working principle of the Bluetooth headset box provided in this embodiment is as follows:

[0085] When it is necessary to switch the lid 3 from the closed state to the open state, the second push rod 301 is pushed into the interior of the box body 1. The second push rod 301 drives the second swing rod 302 to rotate, and the second swing rod 302 drives the positioning member 7 to move downward, so that the first engaging portion 71 is disengaged from the second engaging portion 33, thereby releasing the locking of the first lid 31 and the second lid 32. At this time, under the action of the first elastic member 5 and the second elastic member 6, the first lid 31 and the second lid 32 move in the direction away from each other, so as to realize the automatic opening of the lid 3. After that, under the action of the sixth elastic member 305, the first push rod 201 moves outward of the box body 1 and automatically returns to its original position, and the positioning member 7 moves upward and automatically returns to its original position.

[0086] When it is necessary to switch the lid 3 from the open state to the closed state, the first lid 31 and the second lid 32 are manually clamped. The first lid 31 overcomes the acting force of the first elastic member 5, and the second lid 32 overcomes the acting force of the second elastic member 6, and the two move in the direction close to each other. When the first lid 31 and the second lid 32 move to the closed position, the second engaging portion 33 is engaged with the first engaging portion 71, and the positioning member 7 keeps the first engaging portion 71 and the second engaging portion 33 in the engaged state under the action of the sixth elastic member 305, thereby realizing the locking of the positions of the first lid 31 and the second lid 32.

[0087] The structure of the Bluetooth headset box in this embodiment is compact, small and portable, and the opening of the lid is simple, which improves the convenience and practicality of operation, meets the user's pursuit of product innovation and personalization, and brings a better use experience to the user.

The main difference between the Bluetooth headset box provided in this embodiment and that in Embodiment 1 lies in the different unlocking mechanisms, and the same structures as those in Embodiment 1 will not be described in detail herein.

[0090] Refer to Figure 15 and Figure 16, the specific structure of the unlocking mechanism in this embodiment is as follows: The driving rod is the third push rod 401, and the transmission member includes a connecting rod 402, a third swing rod 403, and a fourth swing rod 404. The third push rod 401 extends along the second direction. The first end of the third push rod 401 slidably penetrates through the side wall of the box body 1. The lower end of the connecting rod 402 is hinged to the second end of the third push rod 401. The upper end of the connecting rod 402 is hinged to the fixed rod 8 and the lower end of the third swing rod 403 through a rotating shaft, and the rotating shaft can move up and down along the fixed rod 8; the upper end of the third swing rod 403 is hinged to the lower end of the fourth swing rod 404, and the upper end of the fourth swing rod 404 is hinged to the lower end of the positioning member 7. When the operator pushes the third push rod 401 into the box body 1, it can drive the connecting rod 402 to rotate, and the upper end of the connecting rod 402 moves upward, thereby driving the third swing rod 403 to rotate. The third swing rod 403 drives the fourth swing rod 404 to rotate, and the fourth swing rod 404 drives the positioning member 7 to move downward, thereby realizing the unlocking of the first cover body 31 and the second cover body 32. Optionally, a button is further provided at the first end of the third push rod 401 to facilitate the user's pressing operation.

[0091] The reset member in this embodiment is the seventh elastic member 405. The seventh elastic member 405 is arranged between the second end of the third push rod 401 and the fixed rod 8. The seventh elastic member 405 has a tendency to move the third push rod 401 toward the outside of the box body 1. Optionally, the seventh elastic member 405 is a compression spring. When the third push rod 401 is pushed into the box body 1, the seventh elastic member 405 is compressed by force. When the third push rod 401 is released, the seventh elastic member 405 can move the third push rod 401 back to its original position toward the outside of the box body 1; at the same time, the third push rod 401 drives the positioning member 7 to move upward and reset through the connecting rod 402, the third swing rod 403, and the fourth swing rod 404.

[0092] Furthermore, arc-shaped abutting surfaces are provided at both ends of the connecting rod 402, both ends of the third swing rod 403, and both ends of the fourth swing rod 404. At the same time, arc-shaped abutting surfaces are also provided at the second end of the third push rod 401 and the lower end of the positioning member 7. The third push rod 401 and the connecting rod 402, the connecting rod 402 and the third swing rod 403, the third swing rod 403 and the fourth swing rod 404, and the fourth swing rod 404 and the positioning member 7 are all abutted through the arc-shaped abutting surfaces. The setting of the above arc-shaped abutting surfaces improves the smoothness of the movement of the connecting rod 402, the third swing rod 403, and the fourth swing rod 404, and ensures the reliable operation of the mechanism.

[0093] The working principle of the Bluetooth headset box provided in this embodiment is as follows:

[0094] When it is necessary to switch the lid 3 from the closed state to the open state, the third push rod 401 is pushed into the interior of the box body 1. The third push rod 401 drives the connecting rod 402 to rotate. The connecting rod 402 drives the positioning member 7 to move downward through the third swing rod 403 and the fourth swing rod 404, so that the first engaging portion 71 is disengaged from the second engaging portion 33, thereby releasing the locking of the first lid body 31 and the second lid body 32. At this time, under the action of the first elastic member 5 and the second elastic member 6, the first lid body 31 and the second lid body 32 move in the direction away from each other, so as to realize the automatic opening of the lid 3. Then, under the action of the seventh elastic member 405, the third push rod 401 moves outward of the box body 1 and automatically returns to its original position, and the positioning member 7 moves upward and automatically returns to its original position.

[0095] When it is necessary to switch the lid 3 from the open state to the closed state, the first lid body 31 and the second lid body 32 are manually clamped. The first lid body 31 overcomes the acting force of the first elastic member 5, and the second lid body 32 overcomes the acting force of the second elastic member 6, and the two move in the direction close to each other. When the first lid body 31 and the second lid body 32 move to the closed position, the second engaging portion 33 is engaged with the first engaging portion 71, and the positioning member 7 keeps the first engaging portion 71 and the second engaging portion 33 in the engaged state under the action of the seventh elastic member 405, thereby realizing the locking of the positions of the first lid body 31 and the second lid body 32.

[0096] The structure of the Bluetooth headset box in this embodiment is compact, small and portable, and the lid opening is simple, which improves the convenience and practicality of operation, meets the user's pursuit of product innovation and personalization, and brings a better use experience to the user.
