Fig. 3-7 are schematic views of a coupling device according to an embodiment of the invention in different operating states. Fig. 8 is a schematic view of the internal structure of the housing of the connecting device according to the embodiment of the present invention. Fig. 9 and 10 are a schematic structural view and a schematic assembly relationship view of the moving assembly, the second elastic member and the slider of the connecting device according to the embodiment of the present invention, respectively. Wherein, fig. 3-8 are schematic views taken along the section A-A in fig. 2.

Referring to fig. 1 to 10, the connection device F includes a housing 100, a moving assembly, and a second elastic member 500. The housing 100 has at least one rail 110 and a catch 120, the catch 120 having a first engagement surface 121. The moving assembly is capable of moving along the track 110. The moving assembly includes a push rod 200, a hook 300 and a first elastic member 400. The hook 300 is rotatably connected with the push rod 200, and the first elastic member 400 is respectively connected with the push rod 200 and the hook 300, so as to realize the elastic connection between the hook 300 and the push rod 200. The hook 300 has a second engaging surface 310 corresponding to the first engaging surface 121, and when the second engaging surface 310 is engaged with and abutted against the first engaging surface 121, the catch 120 can restrict movement of the hook 300, thereby restricting movement of the push rod 200. The second elastic member 500 is connected to the moving assembly. When the second engaging surface 310 engages with the first engaging surface 121, the elastic force of the first elastic member 400 acts on the hook 300 to keep the hook 300 in a predetermined position, so that the second engaging surface 310 faces the first engaging surface 121; the elastic force of the second elastic member 500 acts on the moving component, so that the moving component receives a downward force in the vertical direction, and the moving component keeps a downward movement trend, so that the second engaging surface 310 can keep abutting against the first engaging surface 121, and the hook 300 is prevented from being separated from the catch 120.

In the present disclosure, "up", "down", "horizontal direction" and "vertical direction" are the same as the corresponding directions in fig. 3 to 8, and the description of the directions is for convenience of explaining the positional relationship of the respective parts of the connecting device and the operation principle. It should be understood that the placement of the connecting device F in fig. 3-8 is not necessary in practical applications, and those skilled in the art can adjust the placement of the connecting device according to practical needs.

Referring to fig. 8, the rail 110 includes a locking section 111, a first recovery section 112, and a second recovery section 113, which are connected in sequence. The locking segment 111 is connected to the first recovery segment 112 through a turning point 114, the first recovery segment 112 is connected to the second recovery segment 113 through a top dead center 115, and the second recovery segment 113 is connected to the locking segment 111 through a bottom dead center 116, that is, the first recovery segment 112 extends from the turning point 114 to the top dead center 115, and the second recovery segment 113 extends from the top dead center 115 to the bottom dead center 116. The inflection point 114, the top dead center 115 and the bottom dead center 116 are arranged in a triangle, in other words, the inflection point 114, the top dead center 115 and the bottom dead center 116 are not collinear. The second restoring segment 113 is located at a greater distance from the chuck 120 than the first restoring segment 112 and the locking segment 111. The horizontal distance between the turning point 114 and the clamping platform 120 is smaller than the horizontal distance between the top dead center 115 and the clamping platform 120, and the top dead center 115 is vertically disposed above the turning point 114 and the bottom dead center 116. When the moving assembly is moved from the turning point 114 to the top dead center 115 along the first returning section 112 by an upward force, the second engaging surface 310 of the hook 300 is away from the first engaging surface 121, and the relative height position of the push rod 200 and the housing 100 is changed. When the moving assembly passes the top dead center 115, the moving assembly moves downward along the second restoring segment 113 by the elastic force of the second elastic member 500.

Fig. 11 and 12 are schematic cross-sectional views of two different tracks and limiters according to embodiments of the invention.

The moving assembly may be movably coupled to the track 110 in a variety of ways. In some embodiments, the moving assembly has a stopper 600, and the stopper 600 is shaped to match the rail 110 and can move along the rail 110. The rail 110 may be a groove or a protrusion. In one embodiment, referring to fig. 3-8 and 11, the rail 110 is groove-shaped, and the position-limiting member 600 extends into the rail 110 and moves along the rail 110. In another embodiment, referring to fig. 12, the cross section of the rail 110 is "T" shaped, that is, the stopper 600 spans both sides of the rail 110 and can move along the rail 110.

Referring to fig. 3-7 and 9 and 10, the stopper 600 may be connected to the push rod 200, the hook 300, or other parts of the moving assembly. In some embodiments, the stopper 600 may be a shaft connecting the push rod 200 and the hook 300, and the hook 300 can rotate relative to the push rod 200 by using the stopper 600 as a rotation shaft.

In some embodiments, the bottom dead center 116 is the lowest point of the rail 110, and the height of the inflection point 114 is between the top dead center 115 and the bottom dead center 116. The second recovery section 113 gradually decreases in height from the top dead center 115 to the bottom dead center 116. When the limiting member 600 goes beyond the top dead center 115 and enters the second recovery section 113, the limiting member 600 moves downward to the bottom dead center 116 under the elastic force of the second elastic member 500, and the position of the push rod 200 is the lowest.

The shape of the first returning section 112 can be set arbitrarily as required, so that the stopper 600 can move from the turning point 114 to the top dead center 115 when the push rod 200 is pushed upwards. In some embodiments, the shape of the first returning section 112 is configured such that when the position-limiting element 600 moves from the turning point 114 to the top dead center 115, the second engaging surface 310 gradually moves away from the first engaging surface 121, and the horizontal distance between the hook 300 and the latch 120 gradually increases. For example, the first return segment 112 may be a straight segment or may be a minor arc. The bottom dead center 116 is disposed below the turning point 114 and the top dead center 115, and the bottom dead center 116 may be the lowest point in the rail 110, and when the limiting member 600 moves to the bottom dead center 116, the moving assembly cannot continue to move downward due to the limitation of the limiting member 600 by the rail 110.

Fig. 13 is a schematic position diagram of a housing and a limiting member according to an embodiment of the invention. Wherein fig. 13 is a schematic view of the connection device taken along section C-C in fig. 8.

The housing 100 may be open or may have a hollow cavity to form a semi-enclosed structure. Referring to fig. 1-2 and 8 and 13, in some embodiments, the housing 100 has a receiving cavity therein, the rail 110 and the locking platform 120 are disposed on an inner wall of the receiving cavity, a bottom wall of the housing 100 has a limiting hole 140 communicating with the receiving cavity, and the push rod 200 extends downward and protrudes out of the housing 100 through the limiting hole 140. The limiting hole 140 is used for providing a guiding function for the movement of the push rod 200, and the push rod 200 is prevented from shaking. The length of the push rod 200 extending out of the housing 100 varies as the moving assembly moves along the track 110. Referring to fig. 7, when the limiting member 600 moves to the top dead center 115, the length of the push rod 200 extending out of the housing 100 reaches the minimum value; referring to fig. 3, when the limiting member 600 moves to the bottom dead center 116, the length of the push rod 200 extending out of the housing 100 reaches the maximum; referring to fig. 5, when the second engaging surface 310 of the hook 300 engages with the first engaging surface 121 of the holder 120, the length of the push rod 200 extending out of the housing 100 is between the maximum value and the minimum value.

It should be understood that the limiting hole 140 may be disposed at other positions of the housing 100 according to the requirement of practical application, and the extending direction of the push rod 200 may be changed accordingly. For example, the limiting hole 140 is disposed on the top wall of the housing 100, and the push rod 200 extends upward and penetrates through the top wall of the housing 100, so that when the limiting member 600 moves to the top dead center 115, the length of the push rod 200 extending out of the housing 100 reaches a maximum value; when the limiting member 600 moves to the bottom dead center 116, the length of the push rod 200 extending out of the housing 100 reaches the minimum value. For another example, the limiting hole 140 is disposed on the sidewall of the housing 100, and the push rod 200 also extends in the corresponding direction to penetrate out of the housing 100, so that when the limiting member 600 moves to the top dead center 115, the position of the end of the push rod 200 extending out is the highest; when the limiting member 600 moves to the bottom dead center 116, the position of the end of the pushing member extending out is the lowest.

The second elastic member 500 may be various members or materials capable of applying a certain elastic force to the moving assembly so that the push rod 200 can maintain a downward movement tendency. For example, the second elastic member 500 may be a coil spring, a plate spring, a bungee cord, an elastic material (e.g., rubber, silicone), or the like.

Referring to fig. 3-7 and 9-10, in some embodiments, the connection device F further includes a slider 800, and the moving assembly further includes a stopper 900, and the slider 800 and the stopper 900 are respectively connected to the push rod 200 and spaced apart from each other, wherein the stopper 900 is far away from the housing 100, and the slider 800 is close to the housing 100. In this embodiment, the second elastic member 500 is a spiral compression spring, and the second elastic member 500 is sleeved outside the push rod 200 and disposed between the slider 800 and the stopper 900. The slider 800 has a width greater than the stopper hole 140 so that the position of the second elastic member 500 can be restricted. The surface of the slider 800 in contact with the housing 100 is configured to facilitate sliding along the outer surface of the housing 100. For example, the surface of the slider 800 contacting the housing 100 may be provided as a smooth arc; for another example, the surface of the slider 800 in contact with the housing 100 may be covered with a self-lubricating coating. Therefore, when the push rod 200 is pushed, the limiting member 600 can smoothly move along the rail 110, and the push rod 200 can synchronously move along the corresponding direction along with the position change of the limiting member 600, so that the push rod 200 can always keep a substantially vertical posture (refer to fig. 3-7) in a manner of basically integrally translating during movement, the phenomenon that the moving assembly cannot normally move along the rail 110 due to the overlarge inclination angle of the push rod 200 is avoided, and meanwhile, the identity of the action of the connecting device F during work can be kept.

In one embodiment, referring to fig. 9 and 10, the slider 800 is slidably coupled to the push rod 200, and the stopper 900 is fixedly coupled to the push rod 200. The slider 800 has a hole so as to be fitted over the push rod 200. The end of the push rod 200 protruding out of the housing 100 has an external thread, and the stopper 900 may be a nut. After the slider 800 and the second elastic member 500 are sequentially sleeved on the push rod 200, the stopper 900 is screwed on the external thread of the push rod 200 to be fixed, so that the slider 800 and the second elastic member 500 are prevented from being separated. By adjusting the position of the stop member 900, the pre-tightening force of the second elastic member 500 can be adjusted. Preferably, when the extending length of the push rod 200 is the longest (i.e. when the limiting member 600 moves to the bottom dead center 116), the second elastic member 500 still has a certain pre-tightening force, so that a larger force can be applied when the hook 300 is engaged with the locking platform 120, and the engagement is more stable, and meanwhile, when the limiting member 600 passes through the top dead center 115 and reaches the second returning section 113, the limiting member 600 can be moved downward to the bottom dead center 116 by a sufficient external force.

The first engaging surface 121 and the second engaging surface 310 are matched in shape. The first engaging surface 121 may be a flat surface or an arc surface. For example, the first engaging surface 121 may be a downwardly concave arc surface in the middle, and the second engaging surface 310 is a downwardly convex arc surface corresponding to the first engaging surface 121. In the present embodiment, the first engaging surface 121 is a flat surface provided in the horizontal direction.

In some embodiments, referring to fig. 8 and 13, the housing 100 has a first side wall 150 and a second side wall 160 disposed adjacent to each other, the latch 120 extends from the first side wall 150 in a direction away from the first side wall 150, and the rail 110 is disposed on the second side wall 160. The first and

second sidewalls

150, 160 may form an included angle therebetween, for example, as shown in fig. 13, the first and

second sidewalls

150, 160 may be substantially perpendicular (i.e., the included angle is substantially 90 °). The first returning section 112 is inclined with respect to the first sidewall 150, the top dead center 115 is away from the first sidewall 150 with respect to the turning point 114, and when the limiting member 600 moves from the turning point 114 to the top dead center 115, the second engaging surface 310 is gradually away from the first sidewall 150.

In some embodiments, the housing 100 has two second sidewalls 160 and two rails 110. The two second sidewalls 160 are spaced apart and opposite to each other, the two rails 110 are respectively disposed at the inner sides of the corresponding second sidewalls 160 (i.e., toward the region between the two second sidewalls 160), and the two rails 110 are symmetrically disposed with respect to each other. The moving component is disposed between the two second sidewalls 160, and both ends of the limiting component 600 extend to the two second sidewalls 160 and extend into the corresponding rails 110. The two rails 110 symmetrically disposed may enable the moving assembly to move more smoothly. To facilitate the installation of the housing 100 and the moving component, the housing 100 may include two half-shells, and after the moving component is installed in one half-shell, the two half-shells may be connected and fixed, so that the hook 300 and the limiting member 600 are disposed between the two second sidewalls 160.

Fig. 14 is a schematic view of the connection of the catch and the push rod of the embodiment of the invention.

Referring to fig. 14, in some embodiments, the push rod 200 has a limiting groove 210, the limiting groove 210 has a first limiting surface 211 and a second limiting surface 212, and a third included angle is formed between the first limiting surface 211 and the second limiting surface 212. The hook 300 has a limiting protrusion 330 corresponding to the limiting groove 210, and the limiting protrusion 330 has a third limiting surface 331 and a fourth limiting surface 332, wherein the third limiting surface 331 is disposed opposite to the first limiting surface 211, and the fourth limiting surface 332 is disposed opposite to the second limiting surface 212. A fourth included angle is formed between the third limiting surface 331 and the fourth limiting surface 332, and the fourth included angle is smaller than the third included angle. After the hook 300 is connected with the push rod 200, the position-limiting protrusion 330 is disposed in the position-limiting groove 210 and moves in the area limited by the position-limiting groove 210. Therefore, the limiting protrusion 330 is matched with the limiting groove 210, so that the rotation angle range of the hook 300 relative to the push rod 200 is the difference between the third included angle and the fourth included angle.

The first elastic member 400 may be various members or materials capable of achieving elastic connection between the hook 300 and the push rod 200 so that the hook 300 can maintain a predetermined posture without an external force applied to the moving assembly. For example, the first elastic member 400 may be a coil spring, a torsion spring, a bungee cord, a leaf spring, or the like. In this embodiment, the first elastic element 400 is a helical compression spring, and the first elastic element 400 is disposed in the limiting groove 210 of the push rod 200 and abuts against the limiting protrusion 330 of the hook 300, so that the second engaging surface 310 of the hook 300 and the first engaging surface 121 are substantially parallel to each other when the moving assembly is not subjected to an external force. When the second engaging surface 310 contacts the first engaging surface 121, the elasticity of the first elastic member 400 can prevent the moving component from rotating when the moving component is pulled downward, so that the second engaging surface 310 can be engaged with the first engaging surface 121 well.

The locking base 120 further has a first guide surface 122, the first guide surface 122 is disposed below the first engaging surface 121, the hook 300 further has a second guide surface 320 corresponding to the first guide surface 122, and the second guide surface 320 is disposed above the second engaging surface 310. The second guiding surface 320 and the second engaging surface 310 form a first included angle, and the first included angle is an acute angle. The locking section 111 is located at a position where the stopper 600 is located at the locking section 111 when the second guide surface 320 contacts the first guide surface 122. When the position-limiting member 600 moves to the bottom dead center 116, the hook 300 is located below the locking platform 120, and a certain distance is formed between the second guide surface 320 and the first guide surface 122. When the limiting member 600 moves along the locking segment 111 toward the turning point 114, the distance between the second guiding surface 320 and the first guiding surface 122 gradually decreases until the second guiding surface 320 contacts the first guiding surface 122. When the push rod 200 is further pushed upward, the second guide surface 320 and the first guide surface 122 are pressed against each other, and the first guide surface 122 applies a reaction force to the second guide surface 320. The magnitude of the first angle and the relative position of the second guiding surface 320 and the rotation axis of the hook 300 are set as follows: so that the reaction force of the first guide surface 122 against the second guide surface 320 can urge the hook 300 to rotate counterclockwise in the figure. At this time, the first elastic member 400 is compressed so that the hook 300 can be separated from the first guide surface 122 to continue moving upward. When the hook 300 moves upward and is separated from the locking platform 120, the hook 300 rotates clockwise to be reset under the action of the elastic force of the first elastic element 400, so that the second engaging surface 310 is opposite to the first engaging surface 121. After the pushing force applied to the push rod 200 is removed, the moving assembly moves downward under the elastic force of the second elastic member 500, so that the second engaging surface 310 abuts against the first engaging surface 121, and the push rod 200 cannot move downward due to the blocking of the locking stand 120.

In some embodiments, the locking section 111 extends along a straight line, and the locking section 111 is perpendicular to the first engaging surface 121, so that the moving component can move upwards to complete the engagement with the clamping platform 120. The included angle between the first recovery section 112 and the locking section 111 is a second included angle, and the second included angle is an obtuse angle. The first return segment 112 may be straight, curved or otherwise shaped. Preferably, the height of the first recovery segment 112 gradually increases from the turning point 114 to the top dead center 115, so that when the push rod 200 is pushed upwards, the limiting member 600 can smoothly move along the first recovery segment 112 to the top dead center 115. In one embodiment, the first return segment 112 extends in a substantially linear direction.

In some embodiments, the housing 100 further has a third guiding surface 130 corresponding to the second guiding surface 320, and the third guiding surface 130 is disposed above the first engaging surface 121 and spaced apart from the first engaging surface 121. The third guide surface 130 is parallel to the first guide surface 122. When the moving member moves to the second guiding surface 320 to contact with the third guiding surface 130, the second engaging surface 310 is separated from the first engaging surface 121. In one embodiment, the second guiding surface 320 contacts the third guiding surface 130 when the moving assembly moves to the turning point 114. When the push rod 200 is further pushed upward, the second guide surface 320 and the third guide surface 130 are pressed against each other, and the third guide surface 130 applies a reaction force to the second guide surface 320. The reaction force of the third guiding surface 130 to the second guiding surface 320 has a component force in the horizontal direction to the hook 300, and at the same time, the hook 300 can be pushed to rotate counterclockwise in the figure to disengage from the third guiding surface 130, so that the moving assembly can smoothly move upward along the inclined first returning section 112.

Fig. 15 and 16 are schematic views illustrating the working principle of the stopper spring according to the embodiment of the invention.

In some embodiments, referring to fig. 3 to 8 and fig. 15 and 16, the connecting device F further includes two stopping

resilient pieces

710 and 720, and the stopping

resilient pieces

710 and 720 are disposed on the track 110 for moving the moving assembly in a predetermined direction in the track 110. The two stopper springs 710, 720 may have the same shape. The two stopping elastic pieces include an upper stopping elastic piece 710 and a lower stopping elastic piece 720, wherein the upper stopping elastic piece 710 is disposed corresponding to the upper stopping point 115, the upper stopping elastic piece 710 is configured to block the limiting member 600 from entering the first recovery section 112 from the second recovery section 113 through the upper stopping point 115, the lower stopping elastic piece 720 is disposed corresponding to the lower stopping point 116, and the lower stopping elastic piece 720 is configured to block the limiting member 600 from entering the second recovery section 113 from the locking section 111 through the lower stopping point 116. The shape of the stopper springs 710 and 720 can be set according to actual needs.

In one embodiment, the stopper springs 710, 720 have a fixed end and a free end. The fixed end is fixedly connected with the rail 110, and the free end extends into the rail 110 to partially shield the rail 110. The fixed end of the upper stop spring 710 is fixed on one side wall of the first return section 112, and the free end extends into the rail 110 and extends toward the direction close to the upper stop 115. Referring to fig. 15, when the limiting member 600 moves in the first returning section 112 toward the top dead center 115 (i.e., moves in a counterclockwise direction in the figure), the limiting member 600 presses the free end of the top stop spring 710 against the sidewall where the fixed end of the rail 110 is located, so as to enter the second returning section 113 through the top dead center 115. Referring to fig. 16, when the limiting member 600 moves to the top dead center 115 at the second recovery section 113, and the limiting member 600 abuts against the free end of the top stop spring sheet 710, the free end of the top stop spring sheet 710 stops the limiting member 600, and when the limiting member 600 continues to move clockwise in the track 110 in the figure, the free end of the top stop spring sheet 710 is turned over to the opposite side of the side wall of the track 110 where the fixed end is located under the acting force of the limiting member 600, so that the shielding area of the top stop spring sheet 710 on the first recovery section 112 is increased, and the limiting member 600 cannot pass through. Similar to the upper stopper spring 710, the fixed section of the lower stopper spring 720 is fixed on a sidewall of the second recovery section 113, and the free end extends into the rail 110 and extends toward the bottom dead center 116. Therefore, the limiting member 600 can smoothly enter the first recovering section 112 from the second recovering section 113 through the bottom dead center 116, and when the limiting member 600 moves from the bottom dead center 116 to the second recovering section 113 clockwise in the figure, the limiting member is blocked by the lower stopping elastic sheet 720. That is, the position-limiting member 600 can move in the track 110 in the counterclockwise direction in the drawing smoothly, and is blocked by the blocking

elastic pieces

710 and 720 when moving in the clockwise direction, so that the push rod 200 can move in a certain direction each time it is pushed.

The operation of the connecting device F will now be described with reference to fig. 3-7.

When the limiting member 600 is located at the locking section 111 and the hook 300 is located below the locking platform 120 (see fig. 3), the push rod 200 is pushed upward, so that the hook 300 moves upward to pass over the locking platform 120 (see fig. 4), and the second engaging surface 310 moves to above the first engaging surface 121. At this time, when the pushing force on the push rod 200 is removed, the second engaging surface 310 is brought into contact with and engaged with the first engaging surface 121 by the elastic force of the second elastic member 500 (see fig. 5), and the push rod 200 is held at a fixed position and cannot move downward, thereby achieving locking. When the push rod 200 is pushed upward again (see fig. 6), the second engaging surface 310 is separated from the first engaging surface 121, the limiting member 600 moves upward along the first returning section 112, goes over the top dead center 115 (see fig. 7), and after the pushing force on the push rod 200 is removed, the moving assembly moves downward along the second returning section 113 under the action of the elastic force of the second elastic member 500, and returns to the original position (see fig. 3), so as to unlock the lock. The position of the push rod 200 is lower than that when the hook 300 is locked with the locking platform 120.

The connecting device F in the embodiment of the invention can be applied to electronic equipment and can play a role in indicating whether a specific component is installed in place and/or facilitating assembly and disassembly of the components.

The electronic device may be various forms of electronic devices including, but not limited to, smart wearable devices, cell phones, computers, headsets, digital cameras, and the like. The electronic equipment comprises an equipment body and at least one connecting device F in at least some embodiments of the disclosure, wherein the connecting device F is connected with the equipment body. The housing 100 of the connecting device F may be fixedly connected with the apparatus body. In some embodiments, the electronic device has a cavity for mounting the detachable component, into which the push rod 200 of the attachment means F protrudes. When the specific detachable component is pushed into the cavity, the push rod 200 is pushed, and the moving component moves along the locking section 111, so that the clamping hook 300 is clamped with the clamping table 120 to realize locking; when the detachable component is pushed again, the push rod 200 is pushed again, the hook 300 leaves the catch 120, the moving assembly moves along the first recovery section 112 and goes over the top dead center 115, and the push rod 200 can eject the detachable component out of the cavity during the moving assembly moves along the second recovery section 113 under the action of the elastic force of the second elastic member 500.

For example, the electronic apparatus may be a card-insertable electronic apparatus having a detachable memory card, the electronic apparatus may have a card slot for insertion of the memory card, and the connecting device F may be provided at the bottom of the card slot, and the push rod 200 may extend into the card slot. When the memory card is pushed into the card slot, the push rod 200 is pushed to enable the hook 300 to be clamped with the clamping table 120, the length of the push rod 200 extending into the card slot is short, and the memory card can be completely pushed into the card slot. When the memory card needs to be taken out, the memory card is pushed towards the bottom of the card slot again, the push rod 200 is pushed, and the moving assembly moves along the first recovery section 112 and the second recovery section 113, so that the memory card can be partially or completely ejected out of the card slot, and the memory card is convenient to take out.

Fig. 17 is a schematic structural diagram of a wireless headset according to an embodiment of the present invention. Fig. 18 is a schematic diagram of a wireless headset with a battery removed according to an embodiment of the present invention.

Referring to fig. 17 and 18, in some embodiments, the connection device F of at least some embodiments of the present disclosure can be applied to a wireless headset. The wireless headset comprises a headset body E and at least one connecting means F. The earphone body E has a battery chamber E10 for accommodating the battery B, and the battery chamber E10 has an opening E11 for passing the battery B. The connecting device F is connected with the earphone body E, and the push rod 200 extends into the battery chamber E10 and is opposite to the opening E11. When the battery B needs to be loaded into the battery compartment E10, the battery B is pushed into the battery compartment E10 from the opening E11, the battery B pushes the push rod 200 to move, the moving assembly moves along the locking section 111, and the second engaging surface 310 of the hook 300 engages with the first engaging surface 121 of the holder 120, so as to achieve locking, and at this time, the battery B is completely placed into the battery compartment E10 (see fig. 17). Battery compartment E10 has contacts corresponding to battery B, and connecting device F is positioned according to the positions of the contacts, so that battery B can contact with the contacts in battery compartment E10 to realize electrical connection when hook 300 is engaged with clip 120. When the battery B is not pushed into the position and the hook 300 is engaged with the engaging platform 120, a part of the battery B still exposes the opening E11, so that the user can determine whether the battery B is mounted in the position according to whether the battery B is exposed out of the opening E11. When the battery B needs to be taken out, the battery B is pushed into the battery compartment E10 again, so that the moving assembly moves along the first recovery section 112 and enters the second recovery section 113, and under the action of the elastic force of the second elastic member 500, the push rod 200 ejects the battery B outwards, so that a part of the battery B is exposed out of the opening E11 (refer to fig. 18), and the battery B is convenient to take out.

Referring to fig. 17 and 18, in some embodiments, the wireless headset includes two connection devices F disposed in parallel at a certain distance, so that the battery B can be more stably placed in the battery compartment E10, and at the same time, a greater ejection force can be provided when the battery B is removed. In one embodiment, the two connecting devices F may be symmetrically disposed, so that the horizontal acting force of the moving assembly on the battery B during the moving along the rail 110 can be offset, and the placing and taking out process of the battery B is more stable.

The wireless earphone has the advantages that by adopting the connecting device disclosed by the embodiment of the disclosure, a user can finish the loading and unloading of the battery through the pushing action, so that the user can conveniently disassemble and assemble the battery, and meanwhile, the user can conveniently judge whether the battery is installed in place when installing the battery. When the battery electric quantity of the wireless earphone is lower, a new battery can be conveniently replaced, thereby reducing peacocks in service time caused by charging the wireless earphone and facilitating the use of users. When the performance of the battery is reduced, the battery can be replaced by a new one, so that the service life of the wireless earphone is prolonged.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
