Disclosure of Invention

The embodiment of the application provides a charging device, which is used for providing a structure that a USB plug of the charging device can be retracted into the charging device and can extend out of the charging device.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme:

in a first aspect, there is provided a charging device comprising: the plug comprises a shell, a plug, a deflector rod and a first conversion structure; the plug is connected to the shell in a sliding way; the deflector rod is rotationally connected with the shell; the driving lever is connected with the plug through a first conversion structure, and the first conversion structure is used for converting the rotary motion of the driving lever into linear motion of the plug; when the deflector rod rotates relative to the shell, the plug can be driven to slide relative to the shell through the first conversion structure so as to slide out of the shell or retract into the shell.

Based on the above-described structure of the charging device according to the embodiment of the present application, it can be seen that the plug of the charging device is slidable relative to the housing, and when the charging device is in the uncharged state, the plug can be retracted into the housing of the charging device; when the charging device is in a charging state, the plug can extend out of the shell of the charging device. The charging device provided by the embodiment of the application not only meets the convenience in charging, but also can retract the plug into the shell when not being charged, thereby playing a role in protecting the plug and prolonging the service life of the charging device. The product is attractive and can be stored, and the use is convenient for users.

The shift lever and the first conversion structure cooperate to convert rotation of the shift lever relative to the housing into linear movement relative to the plug as a structure for pushing the plug to slide relative to the housing. Specifically, the first conversion structure converts the power generated by the rotation of the shift lever into a force for pushing the plug to linearly move, and the force generates a guiding effect on the sliding of the plug relative to the housing, wherein the guiding effect is to push the plug along the pushing-out direction or along the retracting direction (opposite to the pushing-out direction), so that the plug linearly moves relative to the housing under the guiding effect.

Compared with the mode that the deflector rod and the first conversion structure are not arranged, the rotation of the deflector rod is converted into the sliding of the plug relative to the shell only by directly pushing the structural member to drive the plug to move in a straight line, and the size of the charging device can be reduced by adjusting the connection position of the first conversion structure and the plug, the connection position of the first conversion structure and the deflector rod and the connection position of the deflector rod and the shell, and the sliding range of the plug relative to the shell between the three positions.

In addition, the structure of the deflector rod is simple, the movement flexibility is high, the occupied space is small, and the setting requirement of the charging device for small size can be met.

When the deflector rod rotates, the first guide post can slide relative to the first guide hole. The first guide hole is matched with the first guide column in a contact mode, and the side wall of the first guide hole can give pushing force to the first guide column due to the power of rotation of the deflector rod, so that the first guide column can drive the plug to move linearly along the direction of the pushing force. The hole column is matched with the mode, the reliability is high, the structure is simple, the occupied space is small, and the setting requirement of the charging device for small size can be met.

In one possible implementation, one end of the lever is rotatably connected to the housing; a first guide post is arranged at the other end of the deflector rod; the plug is provided with a first guide hole; the deflector rod is arranged on the first guide hole in a penetrating mode through the first guide column, and the first guide column can slide relative to the first guide hole.

When the driving lever drives the plug to extend out of the charging device, the first elastic piece can store energy in the rotating process of the driving lever; when the driving rod drives the plug to retract into the charging device, the first elastic piece can drive the driving rod to rotate continuously when the small part of the plug is positioned outside the shell, so that the plug can retract continuously along the retracting direction until all the plug retracts into the charging device.

In one possible implementation, the first resilient member may be a torsion spring. The torsion spring can store and release angular energy and can provide the deflector rod with pressing force and damping effect. In addition, in the process of pushing out the plectrum, the torsional spring can be used for adjusting the difficulty degree of pushing out.

In one possible implementation, the charging device further includes: the poking piece is in sliding connection with the shell, and the direction of linear motion of the poking piece is consistent with that of the plug; the second conversion structure is connected with the deflector rod through the deflector plate, and is used for converting the linear movement of the deflector plate into the rotary movement of the deflector rod; when the shifting piece slides relative to the shell, the shifting rod can be driven to rotate relative to the shell through the second conversion structure.

The shifting piece is used for controlling the shifting rod to slide, and the shifting rod is further rotated relative to the shell, so that the plug can be controlled to slide relative to the shell only through the action of pushing the shifting piece, and the use experience of a user is improved.

In one possible implementation, the position where the dial and the dial lever are connected through the second switching structure is closer to the position where the dial lever is rotationally connected with the housing than the position where the dial lever and the plug are connected through the first switching structure.

When the shift piece slides relative to the shell, the shift lever rotates relative to the shell, and the linear displacement of the position on the shift lever, which is in rotary connection with the shift lever, is larger than the linear displacement of the position on the shift lever, which is in connection with the plug, is larger than the linear displacement of the position on the shift lever, which is in connection with the shift lever. Thus, the pulling piece moves a small distance, so that the plug can move a large distance, and the operation can be more labor-saving.

In one possible implementation, the second conversion structure includes a paddle guide slot and a second guide post; the poking piece guide groove is arranged on the poking piece, and the second guide post is arranged on the poking rod; wherein, the extending direction of the poking piece guide groove is consistent with the sliding direction of the plug; the plectrum guide way wears to locate on the second guide post, and when plectrum rectilinear movement, the second guide post can slide along the extending direction of plectrum guide way in the plectrum guide way to drive the relative casing of driving the driving lever and rotate.

By arranging the self-locking structure, when the plug completely extends to the shell, the plug is clamped with the shell through the self-locking structure, so that the plug cannot extend continuously even if the pulling piece is pushed continuously along the pushing direction, and the plug is prevented from being separated from the connection position of the plug and the shell; and moreover, the pulling piece is pushed along the retreating direction, so that the plug cannot retreat relative to the shell, and the use experience of a user is improved.

Through setting up unlocking structure, when the plug needs to fall back to the casing, promote the plectrum along the backspacing direction, unlocking structure will be in the plug and the casing unblock of interlocking state, and the plug can fall back to in the casing.

In one possible implementation, the self-locking structure comprises: the self-locking guide post hole and the self-locking guide post are arranged on the shell; the extending direction of the self-locking guide post is vertical to the direction of the linear motion of the plug; the second elastic piece is used for giving elasticity perpendicular to the direction of the linear motion of the self-locking guide post and the plug after the plug slides out of the shell, so that the self-locking guide post is inserted into the self-locking guide post hole.

When the pulling piece is positioned at the initial position, namely the plug is positioned in the shell, the second elastic piece is in a compressed state. The pulling piece is pushed along the pushing-out direction until the plug extends out of the shell, and the second elastic piece is still in a compressed state. When the pulling piece is pushed continuously along the pushing-out direction, the second elastic piece is gradually decompressed, and elastic force is given to the self-locking guide post and the plug in a direction perpendicular to the direction of linear motion, so that the self-locking guide post is inserted into the self-locking guide post hole.

In one possible implementation, the self-locking guide post and the unlocking guide post are of an integral structure.

The inclined plane is provided with a first position far away from the self-locking guide column hole and a second position close to the self-locking guide column hole along the axis direction of the self-locking guide column hole, when the plug stretches out of the shell and continuously pushes the shifting piece along the pushing-out direction, the unlocking guide column moves from the first position to the second position along the inclined plane, the elastic piece is gradually decompressed, and the self-locking guide column is pushed to be inserted into the self-locking guide column hole.

The push-out assembly 60 is an important component for pushing out and retracting the plug assembly 10 in the charging device, and the push-out assembly 60 and the connection relationship between the push-out assembly 60 and the plug assembly 10, the housing 20 and the paddle 30 will be described with reference to fig. 5 and 6.

Fig. 5 is a partially disassembled schematic diagram of a charging device according to an embodiment of the present application. As shown in fig. 5, the push-out assembly 60 includes a lever 61 and a first switching structure 62; the deflector rod 61 is rotatably connected with the housing 20; the shift lever 61 is connected to the plug assembly 10 by a first conversion structure 62, the first conversion structure 62 being used for converting a rotational movement of the shift lever 61 into a linear movement of the plug assembly 10; when the shift lever 61 rotates relative to the housing 20, the first conversion structure 62 can drive the plug assembly 10 to slide relative to the housing 20, so as to slide out of the housing 20 or retract into the housing 20.

As shown in fig. 5, in some embodiments, the plug assembly 10 includes a plug 11, and a boss 14. Wherein the plug 11 is for insertion into a universal joint; the boss 14 is used to locate the structural member and to cooperate with components in the charging device to effect extension and retraction of the plug 11 relative to the housing.

As shown in fig. 5, in some embodiments, the first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on the plug 11. The first guide hole 621 extends in a radial direction a-a' of the rotational movement path of the lever 61.

Fig. 6 is a schematic structural view of the charging device shown in fig. 5 after assembly. Referring to fig. 5 and fig. 6 together, the first guide hole 621 penetrates the first guide post 622, and when the lever 61 rotates, the first guide post 622 can slide in the first guide hole 621 along the extending direction of the first guide hole 621, so as to drive the plug 11 to move linearly. Because of the contact and cooperation between the first guide hole 621 and the first guide post 622, the sidewall of the first guide hole 621 can push the first guide post 622 by the power of the rotation of the lever 61, so that the first guide post 622 can drive the plug 11 to move linearly along the direction of the pushing force. For example, when the paddle 30 is pushed in the retracting direction as shown in fig. 6, the sidewall of the first guide hole 621 may provide the first guide post 622 with the pushing force F due to the power of the rotation of the lever 61, the direction of the pushing force F is consistent with the direction of the linear movement of the paddle 30, and the pushing force F drives the plug 11 to move linearly along the direction of the pushing force F. The hole column is matched with the mode, the reliability is high, the structure is simple, the occupied space is small, and the setting requirement of the charging device for small size can be met.

In some embodiments, a first guide hole 621 is provided on the plug 11 and a first guide post 622 is provided on the lever 61. The first guide hole 621 extends in a radial direction a-a' of the rotational movement path of the lever 61.

In some embodiments, the first conversion structure 62 includes intermeshing gears and racks, the gears being disposed on the shift lever 61, the racks being disposed on the spigot 11.

With continued reference to fig. 5, in some embodiments, the push-out assembly 60 further includes a first resilient member 63 having one end fixedly coupled to the lever 61 and the other end fixedly coupled to the housing 20. It should be noted that, the first elastic member 63 is connected to the rotating end of the lever 61, so that when the lever 61 rotates, the first elastic member 63 can deform to store or release energy.

Referring to fig. 5 and 6 together, when the plug 11 slides out of the housing 20, the lever 61 rotates in the first direction, and the first elastic member 63 is stretched to deform; when the plug 11 is retracted into the housing 20, the lever 61 rotates in a second direction opposite to the first direction, and the stretched first elastic member 63 gradually returns to its shape; when the driving lever 61 drives the plug 11 to retract into the charging device, and when a small part of the plug 11 is still located outside the housing 20, the first elastic member 63 can drive the driving lever 61 to rotate continuously due to the elastic force generated by the gradual recovery deformation, so as to drive the plug 11 to retract into the housing. The first direction may be the opposite direction to the retraction direction shown in fig. 6, and the second direction may be the retraction direction shown in fig. 6.

In one possible implementation, the first resilient member 63 may be a torsion spring. The torsion spring can store and release angular energy and can provide the deflector rod with pressing force and damping effect. In addition, the torsion spring may be used to adjust the ease of pushing out during pushing out of the paddle 30.

The connection relationship between the push-out member 60 and the plug 11 and the housing 20 are described above, and the connection relationship between the push-out member 60 and the dial 30 is described below.

With continued reference to fig. 6, the paddle 30 is connected to the lever 61 by a second conversion structure 64, and the second conversion structure 64 is used for converting the linear movement of the paddle 30 into the rotational movement of the lever 61; when the shift plate 30 slides relative to the housing 20, the shift lever 61 can be driven to rotate relative to the housing 20 by the second switching structure 64. The shift lever 61 is controlled to slide through the shift piece 30, so that the shift lever 61 rotates relative to the shell 20, and thus the plug 11 can be controlled to slide relative to the shell 20 only through the action of pushing the shift piece 30, and the use experience of a user is improved.

As shown in fig. 6, in one embodiment, the second switching structure 64 includes a tab guide groove 641 and a second guide post 642, the second guide post 642 being disposed on the lever 61, the tab guide groove 641 being disposed on the tab 30. Wherein the extending direction b-b' of the plectrum guide groove 641 is consistent with the sliding direction of the plug 11; the second guide post 642 is penetrated by the plectrum guide groove 641, and when the plectrum 30 moves linearly, the side wall of the plectrum guide groove 641 pushes the second guide post 642 to move together, so that the second guide post 642 can slide along the extending direction b-b' of the plectrum guide groove 641 in the plectrum guide groove 641, and the second guide post 642 can drive the plectrum 61 to rotate relative to the shell 20 due to rotatable connection between the plectrum 61 and the shell 20, thereby converting the linear motion of the plectrum 30 into the rotary motion of the plectrum 61.

In some embodiments, a paddle guide slot 641 is open at the first end 311.

In some embodiments, the position where the paddle 30 is coupled to the lever 61 via the second switch structure 64 is closer to the position where the lever 61 is rotationally coupled to the housing 20 than the position where the lever 61 is coupled to the plug 11 via the first switch structure 62. That is, as shown in fig. 7, the position where the dial 30 and the dial 61 are connected by the second switching structure 64 is a distance Q from the position where the dial 61 is rotatably connected to the housing 20; a distance W between the position where the lever 61 is connected to the plug 11 by the first conversion structure 62 and the position where the lever 61 is rotatably connected to the housing 20; the distance Q is smaller than the distance W.

It will be appreciated that the push-out distance of the dial 30 can be adjusted by the lever ratio of the lever 61, i.e., the distance Q between the fixing hole 613 of the dial 30 and the second guide post 642, and the ratio of the length W of the lever 61. When the dial 30 slides relative to the housing 20, the linear displacement of the position of the dial 61 where the plug 11 is connected is larger than the linear displacement of the position of the dial 30 where the dial 61 is connected to the dial 61 because the greater the distance between the dial 61 and the position of the dial 61 where the dial 61 is rotatably connected to the housing 20 is larger as the dial 61 rotates relative to the housing 20. Thus, the pulling piece 30 moves a small distance, so that the plug 11 can move a large distance, and the operation can be more labor-saving.

In some embodiments, the second guide post 642 is disposed on the paddle 30 and the paddle guide slot 641 is disposed on the lever 61.

With continued reference to fig. 5 and 6, in some embodiments, the housing 20 includes a lever bracket 23, a first mounting cavity 231 is formed in the lever bracket 23, the plug assembly 10 is disposed in the first mounting cavity 231, and the paddle 30 is disposed outside the lever bracket 23; the deflector rod bracket 23 is provided with a guide groove 232, and the extending direction of the guide groove 232 is consistent with the sliding direction of the plug 11; the first guide post 622 extends into the first guide hole 621 through the guide groove 232, and the first guide post 622 is slidable along the extending direction of the guide groove 232. By providing the guide groove 232, the first guide post 622 slides in the guide groove 232 while the first guide post 622 slides relative to the first guide hole 621, thereby ensuring that the plug 11 moves linearly under the drive of the first guide hole 621.

In one implementation, the length of the guide groove 232 is defined according to the length of the plug 11 protruding out of the charging device, so that the first guide post 622 is guided to prevent over-pushing. In addition, by limiting the length of the guide groove 232, when the plug 11 moves to the end point, the first guide post 622 and the guide groove 232 are abutted, so that the plug 11 is prevented from shaking due to a virtual position after the plug 11 is pushed out to the position.

And, in some embodiments, one end of the lever 61 is fixed to the lever bracket 23 by riveting.

In one implementation, the first resilient member 63 may be fixed to the lever bracket 23 by riveting.

With continued reference to fig. 5, in one implementation, the paddle 30 further includes a paddle body 32; the plectrum body 32 is arranged on the plectrum support 31 and is fixedly connected with the plectrum support 31. Thus, by pushing the plectrum body 32, the plectrum holder 31 is driven to move together.

In one implementation, the paddle body 32 and the paddle holder 31 may be secured together by dispensing.

According to the TWS charging device provided by the application, wireless charging is realized, and the extension and retraction of the plug 11 are realized, so that when the charging device is in an uncharged state, the plug 11 is retracted into the TWS charging device, and the plug 11 is protected. In the whole movement process, the movement range of each part is small, and the structure of each part is compact, so that the space of the charging device is utilized to the maximum.

When the plug 11 of the plug assembly 10 is inserted into the charging head, resistance in the opposite direction is received in the direction of insertion, and the plug 11 may be retracted by the resistance. In order to solve the possible back-off problem of the plug 11, the charging device provided in the embodiment of the application is further provided with a self-locking structure 70. The structure of the self-locking structure 70 is described below with reference to the accompanying drawings.

Fig. 8 is a partially disassembled schematic view of another charging device according to an embodiment of the present application. As shown in fig. 8, the charging device further includes: the plug 11 is connected with the shell 20 through the self-locking structure 70; the unlocking structure 80, the plug 11 is connected with the plectrum 30 through the unlocking structure 80.

Fig. 10 is a schematic structural view of a self-locking structure in the charging device shown in fig. 8. Referring to fig. 8 and 10, in some embodiments, the self-locking structure 70 includes: a self-locking guide post hole 71, a self-locking guide post 74 and a second elastic piece 72. The self-locking guide post hole 71 is formed in the shell 20; the direction of extension c-c' of the self-locking guide post 74 is perpendicular to the direction of linear movement of the plug 11. The self-locking guide post 74 is connected to the plug 11 through the second elastic member 72, and after the plug 11 slides out of the housing 20, the second elastic member 72 is used for giving the self-locking guide post 74 an elastic force perpendicular to the direction of the linear motion of the plug 11, so that the self-locking guide post 74 is inserted into the self-locking guide post hole 71. When the paddle 30 is in the home position, i.e., the plug 11 is located within the housing 20, the second resilient member 72 is in a compressed state. The pulling piece 30 is pushed along the pushing direction until the plug 11 extends out of the housing 20, the second elastic piece 72 is gradually decompressed, and the self-locking guide post 74 is gradually inserted into the self-locking guide post hole 71.

In one implementation, a cavity 12 as shown in fig. 8 is provided on a side wall of the plug 11, and a guide post 13 opposite to the second elastic member 72 of the self-locking structure 70 is provided in the cavity 12, where the guide post 13 is used to implement precompression of the second elastic member 72.

Referring to fig. 8 and 10, in some embodiments, the self-locking structure 70 further includes: a guide post pressing block 73 connected with the plug 11, the guide post pressing block 73 having a guide hole; the self-locking guide post 74 is inserted into the guide hole, and the self-locking guide post 74 is slidably connected with the guide post pressing block 73, so that the self-locking guide post 74 moves along the direction perpendicular to the direction of the linear motion of the plug 11 under the elastic force of the second elastic member 72.

In other embodiments, the self-locking guide post hole 71 may be formed in the plug 11, and the self-locking guide post 74 may be connected to the housing 20 through the second elastic member 72.

Fig. 9 is a schematic view of the assembled charging device shown in fig. 8. As shown in fig. 9, after the plug 11 slides out of the housing 20, the plug 11 is clamped with the housing 20 by the self-locking structure 70, so that the plug 11 and the housing 20 are in an interlocked state. Specifically, referring to fig. 8 and 9, after the plug 11 slides out of the housing 20, the self-locking guide post 74 of the self-locking structure 70 is inserted into the self-locking guide post hole 71, so as to achieve interlocking of the plug 11 and the housing 20.

With continued reference to fig. 8 and 9, the unlocking structure 80 is used to unlock the plug 11 and the housing 20 in an interlocked state when the plug 11 is retracted into the housing 20.

In some embodiments, unlocking structure 80 includes: a plectrum unlocking groove 82 and an unlocking guide post 81; the poking piece unlocking groove 82 is formed in the poking piece 30, and the extending direction of the poking piece unlocking groove 82 is consistent with the direction of the linear motion of the plug 11; the unlocking guide post 81 is fixedly connected with the self-locking guide post 74 and is arranged in the poking piece unlocking groove 82 in a penetrating way; the pulling piece unlocking groove 82 has an inclined plane 821, and when the pulling piece drives the plug 11 to retract, the inclined plane 821 applies a force F' to the unlocking guide post 81 along a direction perpendicular to a direction of linear motion of the plug 11, so as to overcome the elasticity of the second elastic piece 72 to the self-locking guide post 74, and the self-locking guide post 74 is pulled out from the self-locking guide post hole 71.

In some embodiments, the paddle unlock slot 82 is open at the second end 312.

The connection relationship and the relative positional relationship between the respective members of the charging device provided by the embodiment of the application are described above. In order to more clearly explain the working principle of the plug of the charging device provided by the embodiment of the application in the pushing-out and retraction process, the movement track of each part of the plug of the charging device in the pushing-out and retraction process is described in detail below with reference to the accompanying drawings.

Fig. 11a shows a schematic A-A section of a charging device according to an embodiment of the present application. Fig. 11B is a schematic B-B cross-sectional view of the charging device shown in fig. 11 a. Referring to fig. 11a and 11b together, when the plug assembly 10 is in the initial state, i.e. the plug 11 is in the charging device, the guide post pressing block 73 is fixedly connected with the side wall surface of the plug 11, the self-locking guide post 74 is located in the first mounting cavity 231 of the lever bracket 23, and the side wall of the first mounting cavity 231 limits the self-locking guide post 74. At this time, the second elastic member 72 is in a compressed state as shown in fig. 10; meanwhile, a gap L is formed between the unlocking guide post 81 and the guide post pressing block 73. It should be noted that the pre-compression force between the sidewall of the first mounting cavity 231 and the self-locking guide post 74 may be changed by adjusting the compression amount of the second elastic member 72.

During the gradual pushing out of the plug 11 to the outside of the charging device, the second elastic member 72 is always in a compressed state as shown in fig. 10. It will be appreciated that during this process, there is frictional contact between the self-locking guide post 74 and the side wall of the first mounting cavity 231.

Fig. 12 is a schematic structural diagram illustrating a self-locking step of a charging device according to an embodiment of the present application. As shown in fig. 12, when the plug 11 is fully extended out of the housing, the self-locking guide post 74 is opposite to the self-locking guide post hole 71, but the self-locking guide post 74 does not extend into the self-locking guide post hole 71 because the unlocking guide post 81 is located at the first position 821a of the inclined surface 821. Continuing to push the pulling piece 30 along the pushing direction, the unlocking guide post 81 moves from the first position 821a to the second position 821b of the inclined surface 821 of the pulling piece unlocking groove 82, the second elastic piece 72 gradually decompresses in the moving process of the unlocking guide post 81, and the self-locking guide post 74 connected with the unlocking guide post 81 gradually stretches into the self-locking guide post hole 71 under the action of the elastic force of the second elastic piece 72. At this time, as shown in fig. 13, there is no gap between the unlocking guide post 81 and the guide post pressing block 73.

By providing the inclined surface 821, the second elastic member 72 can be gradually decompressed, so as to avoid the instant ejection of the self-locking guide post 74, ensure that the self-locking guide post 74 enters the self-locking guide post hole 71, and avoid the deviation of the ejection direction caused by the unstable elastic force of the second elastic member received by the self-locking guide post 74. Meanwhile, the service life can be prolonged.

It should be noted that, in the direction perpendicular to the pushing direction, the distance between the second position 821b of the paddle unlocking slot 82 and the self-locking guide post hole 71 should ensure that the self-locking guide post 74 can extend into the self-locking guide post hole 71.

The installation position of the self-locking guide post hole 71 is related to the position of the self-locking guide post 74 when the plug 11 moves to the final position.

The length of the self-locking guide post 74 is determined by the fact that the self-locking guide post 74 can extend into the self-locking guide post hole 71.

In the above embodiment, when the plug 11 reaches the end position, the paddle 30 is pushed continuously in order to achieve the self-locking process, but the plug 11 connected to the paddle 30 should not move any more with the movement of the paddle 30. In order to avoid the problem that the plug 11 moves or the plug 11 blocks the movement of the paddle 30 during the self-locking process, the embodiment of the present application provides a structure of the paddle guide slot 641.

Fig. 14 shows a schematic structural diagram of a charging device according to an embodiment of the present application. As shown in fig. 14, in some embodiments, a width margin should be reserved between the paddle guide slot 641 and the second guide post 642 in the push-out direction.

The blade guide groove 641 includes a third position 641a and a fourth position 641b, and when the plug 11 has just reached the end position, the second guide post 642 is positioned at the third position 641a of the blade guide groove 641, and when the blade 30 continues to move in the pushing direction, the plug 11 is pushed out to the proper position and cannot continue to move forward due to the abutment of the first guide post 622 with the guide groove 232, and the second guide post 642 gradually moves toward the fourth position 641b of the blade guide groove 641. Thus, by ensuring the relative positions of the third position 641a and the fourth position 641b in the push-out direction, normal movement of the paddle 30 during self-locking and non-movement of the plug 11 can be ensured.

When the charging device is charged, the plug 11 needs to be retracted into the charging device, and to retract the plug 11 into the charging device, the self-locking guide post 74 extending into the self-locking guide post hole 71 is first retracted into the first mounting cavity 231.

The structure of the pulling piece unlocking slot 82 and the process of retracting the self-locking guide post 74 into the first mounting cavity 231 will be described with reference to the accompanying drawings.

Fig. 15 shows a schematic structural diagram of a charging device according to an embodiment of the present application. As shown in fig. 15, when the paddle 30 is retracted in the retraction direction, the paddle unlocking groove 82 of the paddle holder 31 cooperates with the inclined surface 821 of the self-locking structure 70 to generate a component force perpendicular to the retraction direction, and the component force pulls the self-locking guide post 74 out of the self-locking guide post hole 71 of the paddle holder 31 to unlock the self-locking structure 70. Specifically, during unlocking, initially, the plug 11 is located at the end position, the second guide post 642 is located at the fourth position 641b of the paddle guide slot 641, and when the paddle 30 continues to move in the retracting direction, the second guide post 642 moves along the inclined plane 821 toward the third position 641a of the paddle guide slot 641, and the second elastic member 72 gradually compresses until the self-locking guide post 74 comes out of the self-locking guide post hole 71 of the paddle holder 31. After unlocking, the plectrum support 31 continues to retract along the retracting direction, and drives the plectrum 61 to rotate, so that the plug 11 is driven to retract to the initial position.

In this process, the plug does not practically displace to be retracted due to the clearance between the second guide post 642 and the blade guide groove 641.

The charging device provided by the embodiment can control the push-out assembly and the self-locking structure simultaneously by moving the plectrum assembly. In the process of realizing self-locking of the self-locking structure, the pulling piece component is pushed continuously, the plug is not pushed out continuously, but the self-locking guide post of the self-locking structure can enter the self-locking guide post hole of the pulling rod bracket. In addition, can also avoid the plug to rock back and forth in the release direction to promote the precision of product, optimize user's use and experience and feel.

According to the charging device provided by the embodiment of the application, the pushing-out process and the self-locking process of the plug can be realized through one action of pushing out the poking piece along the pushing-out direction; by one action of retracting the pulling piece along the retraction direction, the unlocking process and the retraction process of the plug can be realized, so that the charging device is convenient to use.

In the above embodiment, the self-locking structure and the unlocking structure in the charging device are of split structures, so that the occupied space is large, and in order to make the charging device more miniaturized, the embodiment of the application also provides another charging device, in which the plug can be pushed out by the cooperation of the guide groove, the first guide hole and the first guide post, and self-locking and unlocking can also be realized, so that the number of parts of the charging device is small, the occupied space of the parts is small, and the miniaturization design of the charging device is facilitated. The following detailed description refers to the accompanying drawings.

Fig. 16 shows a schematic structural diagram of a charging device according to an embodiment of the present application. As shown in fig. 16, in some embodiments, the charging device includes: the housing 20, the plug 11, the lever 61, the first switching structure 62; the plug 11 is slidably connected to the housing 20; the deflector rod 61 is rotatably connected with the housing 20; the shift lever 61 is connected to the plug 11 through a first conversion structure 62, the first conversion structure 62 being used for converting a rotational movement of the shift lever 61 into a linear movement of the plug 11; when the shift lever 61 rotates relative to the housing 20, the plug 11 can be driven to slide relative to the housing 20 by the first conversion structure 62, so as to slide out of the housing 20 or retract into the housing 20.

It can be understood that the plug 11 in the charging device provided in the embodiment of the present application may be a male plug (ma le) or a female plug (femal).

Wherein the first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on the plug 11; the first guide hole 621 extends in a radial direction a-a' of the rotational movement locus of the lever 61; the first guide hole 621 penetrates through the first guide post 622, and when the shift lever 61 rotates, the first guide post 622 can slide in the first guide hole 621 along the extending direction of the first guide hole 621, so as to drive the plug 11 to linearly move.

In this way, the charging device can realize pushing out and retracting of the plug.

In order to achieve self-locking after the plug 11 is pushed out and unlocking before the plug 11 is retracted into the housing 20, referring to fig. 16 and 17a, a guide groove 232 is provided in the housing 20, and the first guide post 622 can enter the first guide hole 621 by passing through the guide groove 232. The guide groove 232 includes a first hole section 232a and a second hole section 232b; the second bore section 232b communicates with the first bore section 232a, the first guide post 622 being able to pass from the first bore section 232a into the second bore section 232b, and the first guide post 622 being able to pass from the second bore section 232b into the first bore section 232 a. The second bore section 232b is located at an end of the first bore section 232a adjacent the plug 11. Thus, during the pushing out of the plug 11, the first guide post 622 moves linearly in the first hole section 232a, and when the plug 11 is pushed out in place, the first guide post 622 enters the second hole section 232b from the tail of the first hole section 232 a. The first guide post 622 moves linearly in the second hole section 232b before the plug 11 is retracted into the housing 20, and the plug 11 is gradually retracted into the housing 20 when the first guide post 622 enters the first hole section 232a from the tail of the second hole section 232 b. It will be appreciated that the movement track of the first guide post 622 is limited by the guide slot 232, and that the first guide post 622 will slide along the extension direction of the first and second hole sections 232a, 232 b.

In some embodiments, the extending direction e-e 'of the first hole segment 232a coincides with the direction of the linear movement of the plug 11 (pushing direction shown in fig. 16 and 17 a), and the extending direction f-f' of the second hole segment 232b makes a first angle α with the direction of the linear movement of the plug 11 (pushing direction shown in fig. 16 and 17 a), and the angle of the first angle α is non-zero, for example, may be 90 °, or may be 70 °. That is, the first and second hole segments 232a and 232b make the guide slot 232a tail bent slot, rather than a straight slot.

And, the first guide post 622 is slidably coupled with respect to the plug 11 in a direction perpendicular to the linear motion of the plug 11. Thus, when the first guide post 622 is within the second bore section 232b, the first guide post 622 moves relative to the plug 11 in a direction perpendicular to the linear motion of the plug 11. To achieve a slidable connection of the first guide post 622 with respect to the plug 11, in one implementation, a sliding groove 6222 is provided on the plug 11, a sliding block 6221 is provided in the sliding groove 6222, the sliding block 6221 may slide with respect to the sliding groove 6222 in a direction perpendicular to the linear movement of the plug 11, and the first guide post 622 is fixed to the sliding block 6221, such that the first guide post 622 may slide with respect to the sliding groove 6222 in a direction perpendicular to the linear movement of the plug 11, and a relative movement of the first guide post 622 and the plug 11 in a direction perpendicular to the linear movement of the plug 11 is achieved.

During the pushing out of the plug 11, the lever 61 rotates in the pushing out direction, the first guide post 622 moves linearly in the pushing out direction in the first hole section 232a, the first guide post 622 and the plug 11 are relatively stationary, and the first guide post 622 and the plug 11 move together outside the housing 20. When the plug 11 is pushed out in place, the shift lever 61 continues to rotate in the pushing direction, the first guide post 622 enters the second hole section 232b from the tail of the first hole section 232a, the first guide post 622 moves in the direction away from the first hole section 232a in the second hole section 232b, the first guide post 622 and the plug 11 are no longer kept relatively stationary, and the first guide post 622 and the plug 11 move relatively in the direction perpendicular to the linear movement of the plug 11. The plug 11 does not continue to slide outwards relative to the housing 20 but remains relatively stationary relative to the housing 20, i.e. the self-locking process after the plug 11 has been pushed out is now completed.

During retraction of the plug 11, the plug 11 is first contacted with self-locking, otherwise, the plug 11 cannot move relative to the housing 20, and cannot return to the housing 20. Before the plug 11 is retracted into the housing 20, the lever 61 is rotated in the retraction direction (i.e., the opposite direction to the push-out direction), the first guide post 622 is moved in the second hole section 232b toward the first hole section 232a, at which time the first guide post 622 and the plug 11 are relatively moved in the direction perpendicular to the linear movement of the plug 11, and the plug 11 is relatively stationary with respect to the housing 20. Until the first guide post 622 moves to the connection position of the first hole section 232a and the second hole section 232b, the shift lever 61 continues to rotate along the retraction direction (i.e., the opposite direction of the push-out direction), and the first guide post 622 can enter the first hole section 232a from the tail of the second hole section 232b, so that the retraction of the plug 11 is realized, that is, the unlocking process before the plug 11 is retracted into the housing 20 is completed. After the unlocking process is completed, the shift lever 61 continues to rotate along the retraction direction (i.e., the opposite direction to the push-out direction), the first guide post 622 moves linearly along the retraction direction in the first hole section 232a, and the plug 11 is gradually retracted into the housing 20 under the driving of the first guide post 622.

In one implementation, to enable easier access of the first guide post 622 from the first bore section 232a into the second bore section 232b, or of the first guide post 622 from the second bore section 232b into the first bore section 232a, the junction of the first bore section 232a and the second bore section 232b is provided with a rounded corner R.

The guiding groove 232 is a groove with a bent tail, and the movement track of the first guiding column 622 is limited by the guiding groove 232, so that the self-locking after the plug 11 is pushed out and the unlocking before the plug 11 is retracted are realized.

After the self-locking is completed, in the process of inserting the plug 11 into the power supply, the power supply may provide an acting force for the plug 11 along the retraction direction, the plug 11 may transmit the acting force to the deflector rod 61 through the first conversion structure 62, the deflector rod 61 may be driven by the acting force to withdraw the first guide post 622 from the second hole section 232b, so that the retraction of the plug 11 is caused, and the action of inserting the plug 11 into the power supply fails. In order to improve the reliability of self-locking and prevent the first guide post 622 from exiting from the second hole section 232b, the charging device provided by the embodiment of the application further includes a third elastic member 65.

One end of the third elastic member 65 is fixedly connected with the shift lever 61, and the other end of the third elastic member 65 is fixedly connected with the housing 20, and an initial state of the third elastic member 65 may be a compressed state. When the plug 11 slides out of the housing 20, the lever 61 rotates in a first direction (i.e., a push-out direction), and when the plug 11 is retracted into the housing 20, the lever 61 rotates in a second direction (i.e., a direction opposite to the push-out direction).

When the shift lever 61 rotates in the first direction, the third elastic member 65 is continuously compressed, and when the rotation of the third elastic member 65 exceeds the zero boundary point, the spring force of the third elastic member 65 becomes the driving force, and the third elastic member 65 in the compressed state is used for giving the elastic force to the shift lever 61 so as to drive the first guide post 622 into the second hole section 232b, and enters the self-locking state. And under the action of the elastic force provided by the third elastic member 65, even if the shift lever 61 receives the force of the plug 11 in the retraction direction, the shift lever 61 can still maintain the self-locking state due to the opposite directions of the component force of the elastic force provided by the third elastic member 65 in the first direction and the force of the plug 11 in the retraction direction. It will be appreciated that, if the pushing of the lever 61 is stopped before the spring force of the third elastic member 65 is not changed into the driving force during the rotation of the lever 61, the lever 61 may be automatically reset, so that the plug 11 cannot be further extended out of the housing 20. The lever 61 should be pushed out of position to ensure that the plug 11 protrudes out of the housing 20.

When the lever 61 rotates in the second direction, the third elastic member 65 is continuously compressed, and when the rotation of the third elastic member 65 exceeds the zero limit point, the spring force of the third elastic member 65 becomes the driving force, and the third elastic member 65 in the compressed state is used for giving the elastic force to the lever 61, and when the plug 11 is retracted in place, since the component force in the first direction of the elastic force provided by the third elastic member 65 to the lever 61 is opposite to the first direction, the automatic pushing out of the plug 11 can be prevented.

The third elastic member 65 and the shift lever 61 may be fixedly connected in various manners, for example, may be glued or inserted through a bolt. In one implementation, the connection between the third elastic member 65 and the lever 61 is disposed on a side of the lever 61 near the plug 11, so as to avoid interference between the third elastic member 65, the lever 61 and the housing 20 between the plug 11, in some embodiments, the housing 20 is provided with an annular groove 23b1, and the extending direction of the annular groove 23b1 coincides with the circumferential direction of rotation of the lever 61.

During self-locking after the plug 11 is pushed out of place, the first guide post 622 needs to enter the second hole section 232b from the junction of the first hole section 232a and the second hole section 232 b. And, during unlocking before the plug 11 is retracted into the housing 20, the first guide post 622 needs to enter the first hole section 232a from the junction of the first hole section 232a and the second hole section 232 b. In both processes, the first guide post 622 is changed in the direction of movement, and the first guide post 622 needs to slide with respect to the plug 11. By providing the third elastic member 65, when the spring force of the third elastic member 65 becomes the driving force, an additional force can be provided to the lever 61 to achieve the path change of the first guide post 622 between the first hole section 232a and the second hole section 232 b.

In order to push the rotation of the shift lever 61, in some embodiments, the charging device further includes the shift plate 30, and the structure of the shift plate 30 and the connection relationship between the shift plate 30 and the shift lever 61 can be referred to the foregoing embodiments, which are not described herein.

To achieve a simple installation of the charging device, as shown in fig. 16, in one implementation, the housing 20 includes a lever bracket 23. The lever bracket 23 includes a first bracket 23a and a second bracket 23b. The first bracket 23a and the second bracket 23b are fixedly connected, and the second bracket 23b is located between the first bracket 23a and the plectrum 30. The plug 11 is provided in the first holder 23a and is relatively slidable with respect to the first holder 23 a. The guide groove 232 is provided on the second bracket 23b, the lever 61 is rotatably connected to the second bracket 23b, and the lever 61 is provided toward a side of the second bracket 23b away from the first bracket 23 a. The first guide post 622 is opposite to the first guide hole 621, and the first guide post 622 is inserted into the first guide hole 621. At this time, if the pulling piece 30 is pushed, the pulling piece 30 drives the pulling rod 61 to rotate, and the pulling rod 61 drives the plug 11 to move linearly.

In order to achieve self-locking after the plug is pushed out and unlocking before the plug is retracted into the housing 20, in addition to the guide groove with the first hole section and the second hole section being provided on the housing 20, a first guide hole comprising a third hole section and a fourth hole section can be provided. The first guide hole including the third hole section and the fourth hole section will be described in detail with reference to fig. 17b of the accompanying drawings.

As shown in fig. 17b, in other embodiments, the first conversion structure 62 includes a first guide hole 621 and a first guide post 622; the first guide hole 621 is provided on the lever 61, and the first guide post 622 is provided on the plug 11; the first guide hole 621 includes a third hole segment 621a and a fourth hole segment 621b; the third hole segment 621a extends along the radial direction o-o' of the rotary motion track of the lever 61, the extending direction of the fourth hole segment 621b forms a third included angle θ with the extending direction of the third hole segment 621a, the angle of the third included angle θ is non-zero (for example, may be 90 ° or may be 100 °), the fourth hole segment 621b is communicated with the third hole segment 621a, and the fourth hole segment 621b is located at a third end 6101 of the third hole segment 621 a. The third hole 621a includes a third end 6101 and a fourth end 6102, where the third end 6101 is far away from the rotation axis of the lever 61 than the fourth end 6102.

In this way, during the process of pushing the plug 11 out of the housing 20, the shift lever 61 is pushed in the pushing direction (consistent with the first direction), the shift lever 61 rotates in the first direction, the first guide post 622 moves in the first guide hole 621 along the extending direction of the third hole section 621a, so as to drive the plug 11 to gradually slide out of the housing 20, when the plug 11 is pushed out in place, the shift lever 61 is continuously pushed in the pushing direction, the first guide post 622 enters the fourth hole section 621b, and the first guide post 622 is limited by the side wall surface of the fourth hole section 621b, so that the plug 11 cannot be driven to slide any more. At this time, if the plug 11 is pushed in the opposite direction of the first direction, the first guide post 622 on the plug 11 is limited by the sidewall surface of the fourth hole segment 621b, and cannot drive the lever 61 to rotate in the opposite direction of the first direction, thereby realizing the self-locking process. If it is desired to retract the plug 11 slid out of the housing 20 into the housing 20, the lever 61 is pushed in the opposite direction to the first direction, and the first guide post 622 gradually withdraws from the fourth hole section 621b and enters the third hole section 621a, at which time the unlocking process is completed. Continuing to push the lever 61 in the opposite direction to the first direction, the plug 11 gradually retreats into the housing 20.

To enable the first guide post 622 to be smoothly withdrawn from the fourth aperture segment 621b, in some embodiments, the charging device further comprises: a fourth elastic member 66; one end of the fourth elastic member 66 is fixedly connected with the shift lever 61, and the other end is fixedly connected with the housing 20. The structure and function of the fourth elastic member 66 can be seen in the first elastic member 63 (shown in fig. 5) of the foregoing embodiment, and will not be described herein. In some application scenarios, the charging device is used for charging a bluetooth headset, such as a TWS charging box, where the charging device is provided with a storage slot (see fig. 3) for placing the bluetooth headset, and for convenience of description, the storage slot for placing the bluetooth headset is hereinafter referred to as a headset bin. In order to realize the opening and closing of the earphone bin relative to the shell (or the ejecting action and the pressing action of the earphone bin relative to the shell), the charging device provided by the embodiment of the application further comprises a fifth elastic piece and a clamping structure, and the charging device with the earphone bin opening and closing function is described below with reference to the accompanying drawings. Fig. 18a shows a schematic structural diagram of another charging device according to an embodiment of the present application. As shown in fig. 18a, the charging device includes a housing 20, a headset housing 50a, a fifth elastic member 90a, and a clamping structure 90b. When the earphone bin 50a is clamped with the shell 20 through the clamping structure 90b, the earphone bin 50a is connected with the shell 20, under the action of clamping, the earphone bin 50a can overcome the elastic force of the fifth elastic piece 90a, the earphone bin 50a is static relative to the shell 20, and the earphone bin 50a is positioned in the shell 20; when the clamping structure 90b breaks the clamping connection between the earphone bin 50a and the housing 20, the earphone bin 50a slides relative to the housing 20 under the action of the elastic force of the fifth elastic member 90 a.

The earphone house 50a is slidably connected to the first stand 23 a. For example, as shown in fig. 18a, a clamping plate 234a may be disposed on the earphone bin 50a, a clamping slot 234b is disposed on the first bracket 23a, the clamping plate 234a is disposed opposite to the clamping slot 234b, and the clamping plate 234a can extend into the clamping slot 234b, so that the clamping plate 234a and the clamping slot 234b can slide relatively, so that the earphone bin 50a and the first bracket 23a can be slidably connected. For example, two of the catching plates 234a may be provided, and two of the catching plates 234a may be provided at opposite sides of the earphone bin 50a in a direction perpendicular to the ejecting direction of the earphone bin. The two clamping grooves 234b may be two, and the two clamping grooves 234b are disposed on two opposite sides of the first bracket 23a along the direction perpendicular to the ejecting direction of the earphone bin, so that the first bracket 23a is located between the two clamping plates 234a, and the two clamping plates 234a are respectively clamped in the opposite clamping grooves 234b, and the clamping plates 234a can slide relatively along the direction parallel to the ejecting direction of the earphone bin relative to the clamping grooves 234b, so as to realize slidable connection between the earphone bin 50a and the first bracket 23 a.

The earphone house 50a is connected to the housing 20 through a fifth elastic member 90 a. The initial state of the fifth elastic member 90a may be a compressed state, and the fifth elastic member 90a is configured to apply an elastic force to the earphone house 50a in a direction consistent with the ejecting direction of the earphone house 50a, so that the earphone house 50a can slide relative to the housing 20 and can be ejected out of the housing 20. That is, the fifth elastic member 90a may provide the driving force to the earphone house 50a, which causes the earphone house 50a to slide with respect to the housing 20. In one implementation, the fifth spring 90a may provide a driving force to the snap plate 234a that enables the snap plate 234a to slide relative to the snap slot 234 b. The fifth elastic members 90a may be provided one as shown in fig. 18a, or may be provided two as shown in fig. 19, and the number of the fifth elastic members 90a may be plural, and the present application is not limited to the number of the fifth elastic members 90 a.

The fifth elastic member 90a is connected with the earphone house 50a and the housing 20 in various manners. For example, the adhesive can be used, and the plug can also be plugged through a plug pin. In one implementation, as shown in fig. 18a, an end of the fifth elastic member 90a, which is far away from the earphone bin 50a, is provided with a first hook 90a1, the housing 20 is provided with a first hook slot 235, and the first hook 90a1 may be hung on the first hook slot 235 of the housing 20. In one implementation, the initial state of the fifth elastic member 90a is a compressed state, the earphone bin 50a may be provided with a second hooking groove, and an end of the fifth elastic member 90a adjacent to the earphone bin 50a may be provided with a second hook, and the second hook may be hung on the second hooking groove of the earphone bin 50a to achieve connection between the fifth elastic member 90a and the earphone bin 50 a. When the housing 20 and the earphone house 50a are released from the engagement relationship, the fifth elastic member 90a in a compressed state applies a force to the earphone house 50a, and the earphone house 50a ejects out of the housing 20 under the force of the force.

It will be appreciated that in some embodiments, an end of the fifth elastic member 90a remote from the earphone house 50a is connected to the housing 20, and an end of the fifth elastic member 90a near the earphone house 50a may be in contact with only the earphone house 50a, and not fixedly connected to the earphone house 50 a. When the housing 20 and the earphone house 50a are released from the engagement relationship, the fifth elastic member 90a in a compressed state applies a force to the earphone house 50a, and the earphone house 50a ejects out of the housing 20 under the force of the force. However, when the earphone house 50a is pushed back into the housing 20, the fifth elastic member 90a may be shifted due to the lack of connection between the fifth elastic member 90a and the earphone house 50a, which is disadvantageous in that the earphone house 50a is repeatedly opened and closed. Therefore, the receiving groove may be formed at the position where the fifth elastic member 90a contacts the earphone bin 50a, and the end of the fifth elastic member 90a near the earphone bin 50a may extend into the receiving groove, even if the earphone bin 50a is ejected out of the housing 20, the end of the fifth elastic member 90a near the earphone bin 50a is still located in the receiving groove, so that the position of the fifth elastic member 90a is not shifted, and repeated opening and closing of the earphone bin 50a can be achieved.

As shown in fig. 18b, the charging device provided by the embodiment of the application can utilize the terminal device (such as the mobile phone 400) to reversely charge the TWS charging box by realizing the pushing action, the retracting action and the self-locking and unlocking functions of the plug, so that the charging convenience and the infinite endurance experience of a user are improved.

Two possible implementation manners of the clamping structure are given below, and the opening and closing manner of the earphone cabin in the charging device is described by combining with a specific implementation manner.

Fig. 19 is a schematic structural diagram of an implementation manner of a clamping structure of the earphone cabin in the charging device shown in fig. 18 a. As shown in fig. 19, in one implementation, the clamping structure 90b includes a rotation lever 91 and a clamping groove 92. It will be appreciated that for clarity of illustration of the shape of the card slot 92, the earphone house 50a shown in fig. 19 is flipped 180 ° vertically as compared to the earphone house 50a shown in fig. 18 a.

The card slot 92 is provided on the earphone house 50 a. Illustratively, the card slot 92 includes a boss 921 and a concave slot 922, the earphone house 50a is provided with the boss 921, the concave slot 922 is formed in the boss 921, and the boss 921 is provided with a notch 921a for insertion.

The rotation lever 91 is provided on the housing 20. The rotation lever 91 is rotatably connected to the housing 20. An extension 912 is arranged at one end of the rotating rod 91 near the clamping groove 92; the extending direction g-g' of the protruding portion 912 forms a second included angle β with the ejecting direction of the earphone bin 50 a; the second included angle β is non-zero (for example, may be 90 ° or may be 100 °), or, one end of the rotating rod 91 near the clamping groove 92 is provided with a structure for hooking the earphone bin 50 a. Specifically, protrusion 912 may enter concave groove 922 through notch 921a. The shape of the protruding portion 912 is not limited by the present application. The protruding portion 912 can extend into the clamping groove 92 to realize the clamping connection between the earphone bin 50a and the housing 20. The protruding portion 912 can be withdrawn from the locking groove 92, thereby releasing the locking between the earphone house 50a and the housing 20. The protrusion 912 can be driven to extend into or withdraw from the locking groove 92 by the rotation of the rotation lever 91, so that the locking or unlocking between the earphone house 50a and the housing 20 can be controlled by only driving the rotation lever 91 to rotate. Illustratively, when the rotation lever 91 rotates in the third direction, the third direction is opposite to the extending direction of the protruding portion 912, the protruding portion 912 withdraws from the locking groove 92, and the locking between the earphone house 50a and the housing 20 is released; when the rotation lever 91 rotates in the fourth direction (opposite to the third direction), the protruding portion 912 is configured to protrude into the locking groove 92, so as to achieve locking between the earphone house 50a and the housing 20. The rotating lever 91 may be a straight lever or a bent lever as shown in fig. 19, and the shape of the rotating lever 91 is not limited to the present application. The rotating lever 91 includes a rotating shaft 913, the rotating shaft 913 is located in the middle of the rotating lever 91, an extending portion 912 is disposed at an end of the rotating lever 91 near the clamping slot 92, a portion of the rotating lever 91 located between the extending portion 912 and the rotating shaft 913 is a first sub-lever 91a, a portion of the rotating lever 91 between an end of the rotating lever 91 far from the earphone house and the rotating shaft 913 is a second sub-lever 91b, the first sub-lever 91a is used for driving the extending portion 912 to move, and the second sub-lever 91b is used for driving the first sub-lever 91a to rotate.

In the initial state, the earphone bin 50a is in a closed state, the earphone bin 50a is completely positioned in the shell 20, and the protruding part 912 protrudes into the clamping groove 92; when the rotating lever 91 is pushed in the third direction, the protruding portion 912 gradually withdraws from the locking groove 92 until the protruding portion 912 is completely pushed out from the locking groove 92, and the locking between the earphone house 50a and the housing 20 by the locking structure 90b is released, so that the earphone house 50a is ejected from the housing 20 under the action of the fifth elastic member 90 a. Thus, the operation of opening the headphone housing 50a is completed. When the earphone bin 50a returns to the housing 20 again, by pressing one side of the earphone bin 50a away from the housing 20, the clamping groove 92 gradually approaches the rotating rod 91, the rotating rod 91 is pushed to rotate along the fourth direction, the protruding part 912 gradually approaches the clamping groove 92, and when the earphone bin 50a is pushed back in place, the rotating rod 91 is continuously pushed to rotate along the fourth direction, and the protruding part 912 gradually enters the clamping groove 92, so that the clamping connection between the earphone bin 50a and the housing 20 is realized.

To push the rotation lever 91 to rotate in the third direction, in one implementation, the charging device further includes a push plate 97, the push plate 97 and the rotation lever 91 are disposed on the same side of the housing 20, and the push plate 97 and the rotation lever 91 are disposed in sequence in the ejection direction. Specifically, the pushing piece 97 and the rotation lever 91 may be provided at a side of the second bracket 23b away from the first bracket 23 a. A shift lever 61 is provided between the push piece 97 and the second bracket 23 b. The pushing piece 97 is provided with a pushing groove 971 at a position close to the rotation lever 91, and the pushing groove 971 may be a U-shaped groove as shown in fig. 18a, and when the pushing piece 97 is pushed in the ejecting direction, the pushing groove 971 can be in contact with the rotation lever 91, thereby pushing the rotation lever 91 to rotate in the third direction.

In one implementation, the end of the second sub-lever 91b near the push plate 97 is circular arc shaped as shown in fig. 18 a. Thereby making it more labor-saving for the pushing piece 97 to push the second sub-lever 91 b.

It will be appreciated that, since the shift lever 61 is disposed between the push plate 97 and the first bracket 23a, in order to enable the push plate 97 to push the rotation lever 91 to rotate, the height of the end of the rotation lever 91 adjacent to the push plate 97 in the direction perpendicular to the push plate 97 is greater than the height of the shift lever 61 in the direction perpendicular to the push plate 97.

The opening and closing of the earphone house 50a is realized, and power for pushing the rotation lever 91 to rotate in the fourth direction needs to be provided. The power source may be various, for example, the rotating rod 91 may be manually pushed, but the manual pushing is not easy to operate, and the operation experience of the user is also poor. Meanwhile, the rotating lever 91 needs to be exposed to the outside of the charging device, which is disadvantageous in the beauty of the charging device. If the actions of the push-back earphone bin 50a can be utilized, the linkage of the two actions of pushing back the earphone bin 50a and pushing the rotating rod 91 to rotate along the fourth direction can be realized, and the operation simplicity of pushing back the earphone bin 50a can be greatly improved. In one implementation, the charging device further includes a sixth elastic member 93; one end of the sixth elastic member 93 is connected to the housing 20, and the other end is connected to the rotation lever 91. For example, the initial state of the sixth elastic member 93 may be in a compressed state, during the process of ejecting the earphone bin 50a out of the housing 20, the rotating rod 91 rotates along the third direction, the sixth elastic member 93 continues to be compressed, when the critical state of the sixth elastic member 93 is exceeded, the spring force of the sixth elastic member 93 becomes a driving force, and when the earphone bin 50a and the housing 20 are released from the clamping connection, the rotating rod 91 rotates along the fourth direction under the action of the driving force, and the sixth elastic member 93 can enable the rotating rod 91 to return to the initial state. When the earphone bin 50a is pushed back into the housing 20, the earphone bin 50a can apply a force to the rotating rod 91, the direction of the force is opposite to the ejecting direction, the acting point of the force can be located at one end of the rotating rod 91 close to the earphone bin 50a, the force can directly act on the protruding portion 912, the earphone bin 50a first makes the rotating rod 91 rotate a certain angle along the third direction, the sixth elastic member 93 continues to be compressed, when the critical state of the sixth elastic member 93 is exceeded, the spring force of the sixth elastic member 93 becomes a driving force, under the action of the driving force, the rotating rod 91 rotates along the fourth direction, and the protruding portion 912 gradually stretches into the clamping groove 92, so that the clamping connection between the earphone bin 50a and the housing 20 is realized.

In order to enable the rotation lever 91 to rotate a certain angle in the third direction during the process of pushing the earphone house 50a back into the housing 20, on the one hand, this may be achieved by setting the initial position of the rotation lever 91, for example, the initial position of the rotation lever 91 forms a certain angle with the ejecting direction of the earphone house 50 a. Alternatively, the rotating lever 91 is inclined with respect to the ejecting direction of the headphone cartridge 50 a. On the other hand, as shown in fig. 19, a chamfer T1 may be provided on the side of the protruding portion 912 close to the headphone housing 50a, and a chamfer T2 may be provided on the card slot 92 at a position opposite to the chamfer T1. At this time, the initial position of the rotation lever 91 may be parallel to the ejecting direction of the earphone house 50 a.

After the earphone house 50a and the housing 20 are released from the engagement relationship, the rotation lever 91 rotates in the fourth direction, that is, rotates under the driving force of the sixth elastic member 93. It can be seen that the effect of the sixth elastic member 93 is important, but the reliability is not high by controlling the rotation of the rotation lever 91 only by the sixth elastic member 93. As shown in fig. 20, in some cases, the rotation angle of the rotation lever 91 in the fourth direction is too large, and at this time, when the earphone house 50a is pushed back into the housing 20, the rotation lever 91 continues to rotate in the fourth direction under the pushing force of the earphone house 50a, so that the protruding portion 912 cannot protrude into the card slot 92 again.

To avoid an excessive angle of rotation of the rotation lever 91 in the third direction, such that the protrusion 912 cannot extend into the catch groove 92 when pushing back the earphone house 50a, as shown in fig. 21, in some embodiments, the catch structure 90b further includes a stop post 94; the stopper post 94 is provided on the housing 20, and a line h-h' between the rotation axis of the rotation lever 91 and the axis of the stopper post 94 is parallel to the sliding direction (i.e., the ejecting direction) of the earphone house 50 a. In this way, the angle at which the rotation lever 91 rotates in the fourth direction is not excessively large, ensuring that the protruding portion 912 can protrude into the catching groove 92.

Fig. 22 is a schematic structural diagram of an implementation manner of a clamping structure of a headset cabin in the charging device shown in fig. 18 a. As shown in fig. 22, in another implementation, the clamping structure 90b includes: a first magnet 95 and a second magnet 96; the first magnet 95 and the second magnet 96 are disposed opposite to each other, and the first magnet 95 is located on the housing 20, and the second magnet 96 is located on the earphone house 50 a.

In the initial state, when the first magnet 95 and the second magnet 96 are in contact, the magnetic attraction between the first magnet 95 and the second magnet 96 is greater than the elastic force of the fifth elastic member 90a, the earphone house 50a is stationary relative to the housing 20, and the earphone house 50a is located in the housing 20. The second magnet 96 is pushed in the ejecting direction of the earphone house 50a, the distance between the first magnet 95 and the second magnet 96 increases, and the magnetic attraction between the first magnet 95 and the second magnet 96 decreases. When the elastic force of the fifth elastic member 90a is greater than the magnetic attraction force, the earphone house 50a slides relative to the housing 20 under the elastic force of the fifth elastic member 90a, and finally, the earphone house 50a is ejected out of the housing 20. Pushing the earphone house 50a in the opposite direction to the ejection direction, the distance between the first magnet 95 and the second magnet 96 decreases, and when the distance between the first magnet 95 and the second magnet 96 decreases to a certain threshold value, the magnetic attraction between the first magnet 95 and the second magnet 96 increases, which can overcome the elastic force of the fifth elastic member 90a, and the first magnet 95 and the second magnet 96 attract each other, and the earphone house 50a returns to the inside of the housing 20.

In order to push the second magnet 96 to move relative to the first magnet 95 so that the distance between the first magnet 95 and the second magnet 96 increases, in some embodiments, the charging device further includes a push plate 97, a protrusion 97a is provided on the push plate 97, a slide 97b is provided on the earphone bin 50a, an extending direction of the slide 97b is parallel to an ejecting direction of the earphone bin 50a, and the protrusion 97a is used for being inserted into the slide 97b, so that the push plate 97 can slide relative to the first magnet 95 along the ejecting direction of the earphone bin 50a, when the protrusion 97a of the push plate 97 moves to an end of the slide 97b away from the first magnet 95, the push plate 97 continues to push the push plate 97 along the ejecting direction of the earphone bin 50a, the push plate 97 drives the earphone bin 50a to slide along the ejecting direction of the earphone bin 50a, and the second magnet 96 provided on the earphone bin 50a moves together along a direction away from the first magnet 95, so that the distance between the first magnet 95 and the second magnet 96 increases. It will be appreciated that there may be a plurality of lugs 97a and a plurality of slides 97 b.

In order to achieve linkage between pushing-out or retracting actions of a plug and opening and closing actions of an earphone bin, the embodiment of the application provides a charging device, which is provided with a poking piece, and a moving thread of the poking piece can achieve the pushing-out or retracting actions of the plug and the opening and closing actions of the earphone bin. The following description refers to the accompanying drawings.

Fig. 23 is a schematic structural diagram of another charging device according to an embodiment of the present application. As shown in fig. 23. In some embodiments, the earphone house 50a and the plug 11 are disposed on opposite sides of the housing 20 in the direction of the linear movement (push-out direction) of the plug 11; the pushing piece 97 is slidably connected with the housing 20, and the direction of linear motion of the pushing piece 97 is consistent with the direction of linear motion of the plug 11; the shift lever 61 and the clamping structure 90b are arranged on two opposite sides of the pushing piece 97; one end of the pushing piece 97 is connected to the shift lever 61 through the second switching structure 64 (as shown in fig. 6), and the other end contacts the locking structure 90b, and the pushing piece 97 is used for pushing the shift lever 61 or the locking structure 90b to rotate. The structure of the second conversion structure 64 may be referred to the foregoing embodiment (as shown in fig. 6), and will not be described herein. The contact manner between the pushing piece 97 and the locking structure 90b can be seen in the foregoing embodiment (as shown in fig. 18 a), and will not be described herein. The connection between the plug 11 and the lever 61 is the same as the aforementioned embodiment (shown in fig. 16), and is not described here.

When the push piece 97 is in the initial position, the earphone house 50a is completely located in the housing 20, and the plug 11 is located in the housing 20. The initial position of the push plate 97 may be a position between the earphone house 50a and the plug 11, for example, the initial position of the push plate 97 may be an intermediate position of the earphone house 50a and the plug 11. When the pushing piece 97 is pushed along the pushing direction of the plug 11, the pushing piece 97 drives the second conversion structure 64 to move along the pushing direction, the poking piece guiding groove post 642 drives the poking rod 61 to rotate along the pushing direction, the poking rod 61 drives the first guiding post 622 of the first conversion structure 62 to move along the pushing direction, the first guiding post 622 drives the plug 11 to slide along the pushing direction, and the plug 11 finally slides to the housing 20. The self-locking process after the plug 11 is pushed out of place is shown in the previous embodiment, and will not be described here. When the plug 11 is located outside the housing 20, when the push piece 97 is pushed in the opposite direction of the push-out direction, the push piece 97 drives the second conversion structure 64 to move in the opposite direction of the push-out direction, the paddle guide slot post 642 drives the lever 61 to rotate in the opposite direction of the push-out direction, the lever 61 drives the first guide post 622 of the first conversion structure 62 to move in the opposite direction of the push-out direction, the first guide post 622 drives the plug 11 to slide in the opposite direction of the push-out direction, and the plug 11 finally retreats into the housing 20. The unlocking process before the plug 11 is retracted is referred to the previous embodiment, and will not be described herein. When the earphone bin 50a is completely located in the housing 20 and the plug 11 is located in the housing 20, when the pushing piece 97 is pushed along the ejecting direction of the earphone bin 50a, the pushing piece 97 pushes the clamping structure 90b to release the clamping relationship between the housing 20 and the earphone bin 50a, and the earphone bin 50a ejects out of the housing 20 under the action of the elastic force of the fifth elastic member 90 a. The outer wall of the earphone bin 50a is pushed back along the opposite direction of the ejecting direction, and the earphone bin 50a can push the clamping structure 90b, so that the shell 20 and the earphone bin 50a are clamped, and the earphone bin 50a is finally pushed back into the shell 20. It will be appreciated that in this embodiment, the push-out direction of the plug 11 is opposite to the ejection direction of the earphone house 50a, and the plug 11 and the earphone house 50a are not simultaneously opened by the push piece 97.

In one use scenario, when charging the earphone, the pushing piece 97 is pushed along the ejecting direction of the earphone bin 50a, after the earphone bin 50a is ejected to the housing 20, the earphone is put into the earphone bin 50a, and then the outer wall of the earphone bin 50a is pushed back along the opposite direction of the ejecting direction, and the earphone bin 50a is pushed back into the housing 20. The push piece 97 can be pushed back to the initial position by providing an elastic member in the housing 20. The pushing piece 97 may be attracted back to the initial position by a magnetic attraction force by providing a magnetic member in the housing 20. At this time, the push piece 97 is pushed in the push-out direction of the plug 11, and the plug 11 gradually protrudes out of the housing 20. After the plug 11 is pushed out in place, the plug 11 is inserted into the power supply, and charging is started. After the completion of the charging, the push piece 97 is pushed in the opposite direction to the push-out direction of the plug 11 until the plug 11 is completely retracted into the housing 20.

It will be appreciated that terminal devices, such as cell phones, tablets, computers, etc., may be used as power sources to charge the charging device.

As shown in fig. 24, the push tab 97 may be the paddle 30 (shown in fig. 5, 6 or 10) described in the previous embodiments. Unlike the structure of the charging device shown in fig. 23 for performing the pushing-out or retracting action of the plug, the structure of the charging device shown in fig. 24 for performing the pushing-out or retracting action of the plug can be seen from the foregoing embodiment (as shown in fig. 5 and 6), and the lever 61 and the engaging structure 90b are both provided on the lever bracket 23. The lever bracket 23 is fixedly connected to the base 21 (as shown in fig. 4 a). The fifth elastic member 90a may be fixedly connected to the lever bracket 23 or may be fixedly connected to the base 21.
