When the pins are not used, the pins can be accommodated in the accommodating cavity; when the pin is used, the sliding assembly can slide relative to the shell assembly only by applying a force to the sliding assembly, so that the pin is driven by the gear set assembly to rotate until a part of the pin is exposed out of the shell assembly, and the pin can be inserted into a target socket. Force application to the sliding assembly can be generally completed with one hand.

Description

Technical Field

[0001] This application relates to the field of adapters, and particularly to adapters. Background Art

[0002] An adapter is an interface converter, which can be an independent hardware interface device that allows a hardware or electronic interface to be connected to other hardware or electronic interfaces, or it can be an information interface used in conjunction with other hardware. A power adapter is a commonly used type of adapter.

[0003] For an adapter with movable pins, especially a power adapter, its pins need to be operated by hand by the user to achieve the open state and the folded state. Usually, two hands are required, and not only force needs to be applied to the pins, but also force needs to be applied to the housing of the adapter. Therefore, it is inconvenient to use.

[0004] Moreover, after being opened or folded, the pins are exposed outside the housing of the adapter, and the pins are easily soiled by foreign objects or dirt, thereby affecting the electrical performance and making it difficult to ensure the service life of the pins.

[0086] This application discloses an adapter, which includes some or all of the technical features of the following embodiments; that is, the adapter includes some or all of the following structures. In one embodiment of this application, an adapter includes a sliding component, a housing component, a gear set component, and pins; the housing component is provided with a receiving cavity, and the sliding component is slidably arranged on the housing component; the gear set component is located in the receiving cavity and is rotatably arranged in the housing component, and the gear set component is in meshing engagement with the sliding component; the pins are fixed on the gear set component; the sliding component is used to rotate the gear set component to drive the pins to rotate in a sliding state, so that the pins are in a retracted state or an extended state, and when the pins are in the retracted state, the transmission component and the receiving cavity jointly form a closed space, and the pins are received in the closed space. The above-mentioned adapter, through the cooperation of the sliding component, the housing component and the gear set component, can retract the pins into the receiving cavity when the pins are not in use; when using the pins, only apply force to the sliding component, and the sliding component can slide relative to the housing component, so as to drive the pins to rotate through the gear set component until part of the pins are exposed outside the housing component, so that they can be inserted into the target socket. And applying force to the sliding component can usually be completed with one hand, so it is convenient for users to use. The following will be combined with Figures 1 to 23 , and the adapter will be described in detail.

[0087] In one embodiment, an adapter 900 is as Figure 1 and Figure 2 shown, which includes a transmission component 100, a housing component 200, a gear set component 300, and pins 400; combined with Figure 3 , the housing component 200 is provided with a receiving cavity 240, and the transmission component 100 is slidably arranged on the housing component 200.

[0088] In each embodiment, the gear set component 300 is located in the receiving cavity 240 and is arranged in the housing component 200. As an example, the gear set 380 in the gear set component 300 is rotatably arranged in the housing component 200. The gear set component 300 is in meshing engagement with the transmission component 100; the pins 400 are arranged on the gear set component 300; the transmission component 100 is used to rotate the gear set component 300 in a sliding state, that is, when the transmission component 100 is in a state of sliding relative to the housing component 200, so as to drive the pins 400 to rotate through the gear set component 300, so that the pins 400 are in a retracted state as Figure 1 and Figure 3 shown, or the pins 400 are in an extended state as Figure 14 and Figure 15As shown, for insertion into a target socket, that is, the pin 400 can be inserted into the target socket when in the deployed state. During the conversion between the storage state and the deployed state, the pin 400 is also in an adjustment state between the storage state and the deployed state as Figure 5 and Figure 6 shown, or as Figure 8 and Figure 9 shown. And when the pin 400 is in the storage state, the transmission assembly 100 and the receiving cavity 240 together form a closed space, and the pin 400 is stored in the closed space. In one embodiment, as Figure 15 shown, when the pin 400 is in the deployed state, the pin 400 is perpendicular to the moving direction 101 of the transmission assembly 100, so as to facilitate insertion into the target socket. As an example, the transmission assembly 100 is slidably disposed on the housing assembly 200, such that when the pin 400 is in the storage state, the receiving cavity 240 is in a closed state as Figure 1 and Figure 3 shown; when the pin 400 is in the adjustment state, the receiving cavity 240 is in a partially open state as Figure 5 and Figure 6 shown, or as Figure 8 and Figure 9 shown; when the pin 400 is in the deployed state, the receiving cavity 240 is in an open state as Figure 14 and Figure 15 shown.

[0089] In one embodiment, as Figure 10 and Figure 17As shown, the housing assembly 200 includes a front cover 210, a middle frame 220, and a bottom cover 230; the front cover 210, the middle frame 220, and the bottom cover 230 jointly enclose to form the accommodation cavity 240; the transmission assembly 100 is disposed on the middle frame 220; the gear set 380 in the gear set assembly 300 is disposed on the middle frame 220. As an example, the gear set assembly 300 is rotatably disposed on the middle frame 220. As an example, the front cover 210 is disposed on the middle frame 220 by screwing or snap - fitting, or is integrally formed with the middle frame 220; the transmission assembly 100 is disposed on the middle frame 220 through a first connecting member 510; the gear set assembly 300, or its fixing bracket 340 and gear set 380, is disposed on the middle frame 220 through a second connecting member 520; the bottom cover 230 is disposed on the middle frame 220 through a third connecting member 530, or is integrally formed with the middle frame 220; and only one of the integrally formed structures of the front cover 210 and the middle frame 220, and the bottom cover 230 and the middle frame 220 exists. That is, if the front cover 210 is integrally formed with the middle frame 220, the bottom cover 230 cannot be integrally formed with the middle frame 220; or if the bottom cover 230 is integrally formed with the middle frame 220, the front cover 210 cannot be integrally formed with the middle frame 220. Such a structural design is conducive to assembling the transmission assembly 100, the housing assembly 200, and the gear set assembly 300.

[0090] In this embodiment, the first connecting member 510, the second connecting member 520, and the third connecting member 530 are all screws. In other embodiments, the first connecting member 510, the second connecting member 520, and the third connecting member 530 may also adopt snap - fit connectors, etc.

[0091] In one of the embodiments, as Figure 17 and Figure 18 shown, the transmission assembly 100 includes a sliding cover 110, a sliding plate 120, a rack plate 130, and a slideway frame 140; Figure 18 In the shown embodiment, the number of slideway frames 140 is a pair. Combining Figure 9 and Figure 10, the slide rail frame 140 is disposed on the housing assembly 200 or its middle frame 220; the sliding plate 120 is disposed under the sliding cover 110 and is slidably disposed in the slide rail frame 140 to cooperate with the gear set assembly 300 to place the pin 400 in a received state or a deployed state; during this process, exemplarily, the sliding plate 120 cooperates with the sliding cover 110 to place the accommodation cavity 240 in a closed state, a partially opened state or an opened state, that is, in the transmission assembly 100, the slide rail frame 140 is fixed relative to the housing assembly 200. Therefore, in other embodiments, the slide rail frame 140 may also be taken as a part of the housing assembly 200 and does not belong to the transmission assembly 100. In this embodiment, the sliding cover 110, the sliding plate 120 and the rack plate 130 are slidable relative to the housing assembly 200. Through the relative sliding of the sliding cover 110 and the housing assembly 200, the sliding cover 110 cooperates with the housing assembly 200 or its face cover 210 and middle frame 220 to jointly close the accommodation cavity 240, so that the pin 400 is enclosed and received in the accommodation cavity 240, thereby protecting the pin 400 when the pin 400 is not in use.

[0092] In one embodiment, for the convenience of applying force, as Figure 14 and Figure 15 shown, the transmission assembly 100 is provided with a force application position 160 on the sliding cover 110. The force application position 160 can be used as a finger placement position or a placement position for other parts for applying force. The force application position 160 is used to better apply force to the transmission assembly by fingers, palms or other parts during use so that the sliding cover 110 and the sliding plate 120 slide on the slide rail frame 140, that is, receive an external force to make the sliding cover 110 and the sliding plate 120 slide on the slide rail frame 140; exemplarily, in one embodiment, the force application position 160 is a convex strip, a groove or a combination of concave and convex structures.

[0093] In one embodiment, as Figure 18 and Figure 21 shown, the edge of the sliding plate 120 is provided with a bending portion 121. Combining Figure 12 , the slide rail frame 140 is provided with a slideway 141 corresponding to the bending portion 121, and the bending portion 121 is slidably disposed in the slideway 141. In this embodiment, as Figure 10 and Figure 12 shown, the sliding plate 120 is respectively provided with a bending portion 121 on both sides, and each bending portion 121 is slidably disposed in a corresponding slideway 141.

[0094] In this embodiment, as Figure 18 and Figure 21As shown, the rack plate 130 is disposed under the sliding cover 110 or the sliding plate 120, and the rack plate 130 has a rack 131, and the rack 131 is in meshing engagement with the gear set assembly 300. As an example, the rack plate 130 is integrally formed with the sliding cover 110 or is disposed under the sliding cover 110 by means of screwing, bonding or welding. As an example, the sliding plate 120 is integrally formed with the sliding cover 110 or is disposed under the sliding cover 110 by means of screwing, bonding or welding.

[0095] After the pins of the traditional adapter are opened, there is no self-locking mechanism provided, and the pins may be reset to the folded state under force. For example, during the process of inserting the pins into a socket strip or a socket, the pins are prone to tipping over. In one embodiment, as Figure 19 and Figure 20 shown, the transmission assembly 100 is provided with a pushing member 150, and the gear set assembly 300 further includes an elastic member 360 and a self-locking member 370 that cooperates with the pushing member 150; the elastic member 360 is elastically abutted against the self-locking member 370, and the self-locking member 370 is configured to elastically avoid the pushing member 150 during the process of the pin changing from the retracted state to the deployed state, and abut against the pushing member 150 to a predetermined position, and then elastically reset to lock the position of the pin 400; the self-locking member 370 is configured to elastically avoid the pushing member 150 during the process of the pin changing from the deployed state to the retracted state to release the locking of the position of the pin 400, and then elastically reset and be separated from the pushing member 150. In this embodiment, the gear set assembly 300 is provided with an elastic member 360, a gear set 380, and a self-locking member 370 that cooperates with the pushing member 150; in combination with Figure 7 and Figure 11 , the pin 400 is disposed on the gear set 380, the gear set 380 is rotatably disposed in the housing assembly 200, and is in meshing engagement with the transmission assembly 100, so that when the transmission assembly 100 is in a sliding state, the gear set 380 rotates; in this embodiment, the gear set 380 is in meshing engagement with the rack 131 of the rack plate 130 of the transmission assembly 100. When the rack plate 130 is in a sliding state, the gear set 380 is driven to rotate by the rack 131, thereby driving the pin 400 to rotate.

[0096] In this embodiment, the elastic member 360 is elastically abutted against the self-locking member 370 as Figure 13 and Figure 16As shown, the self-locking member 370 is configured to elastically avoid the pushing member 150 during the process of the pin changing from the retracted state to the deployed state, abut against the pushing member 150 until a predetermined position, and then elastically reset to lock the position of the pin 400. As an example, the transmission assembly 100 slides on the housing assembly 200 to change the pin from the retracted state to the deployed state. At this time, the receiving cavity 240 changes from a partially open state to an open state. The self-locking member 370 first abuts against the pushing member 150 and elastically retreats under the action of the pushing member 150. Then, the pushing member 150 is adjusted to a certain position. When the pin is in the deployed state and the receiving cavity 240 is in the open state, the self-locking member 370 elastically resets and abuts against the pin 400 to lock the position of the pin 400. With such a structural design, when the receiving cavity 240 is in the open state, the pin 400 partially protrudes outside the housing assembly 200 and its position is locked by the self-locking member 370, it can be inserted into the target socket, and during the insertion process, the pin 400 is not easily tilted.

[0097] Furthermore, the self-locking member 370 is also configured to elastically avoid the pushing member 150 during the process of the pin changing from the deployed state to the retracted state to release the locking of the position of the pin 400, and then elastically reset and be separated from the pushing member 150. Similarly, as an example, the transmission assembly 100 slides on the housing assembly 200 to change the pin from the deployed state to the retracted state. At this time, the receiving cavity 240 changes from the open state to a partially open state. The self-locking member 370 first abuts against the pushing member 150 and elastically retreats under the action of the pushing member 150. Then, the pushing member 150 is adjusted to a certain position. When the pin is in the adjusted state, the self-locking member 370 elastically resets, is separated from the pushing member 150, and is separated from the pin 400 until the pin is in the retracted state. With such a structural design, the unlocking of the pin 400 after being locked is achieved, making the adapter 900 easy to use.

[0098] In one embodiment, as Figure 4 and Figure 22As shown, the gear set assembly 300 is further provided with a fixing bracket 340 which is fixed within the housing assembly 200; the fixing bracket 340 is provided with a gear receiving cavity 349, an elastic member receiving cavity 347 and a self-locking member receiving cavity 348; the elastic member 360 is disposed in the elastic member receiving cavity 347; the self-locking member 370 is disposed in the self-locking member receiving cavity 348; the gear set 380 is disposed in the gear receiving cavity 349; in this embodiment, the gear set assembly 300 is further provided with a spring shaft 361 and a fourth shaft 371, and the spring shaft 361 and the fourth shaft 371 respectively pass through the self-locking member 370; the elastic member 360 is a spring, the spring is sleeved on the spring shaft 361 and is elastically abutted against the self-locking member 370.

[0099] In one embodiment, as Figure 19 and Figure 20 shown, the pushing member 150 is provided with a first inclined surface 151, a first side surface 153 and a second inclined surface 152 which are sequentially connected; the self-locking member 370 is provided with a protrusion 372 and a hook portion 378, and the protrusion 372 is provided with a third inclined surface 373, a second side surface 375 and a fourth inclined surface 374 which are sequentially connected; in combination with Figure 4 and Figure 7 , when the transmission assembly 100 is in a sliding state and the receiving cavity 240 changes from a partially open state to an open state, the second inclined surface 152 and the third inclined surface 373 come into abutment first, and then the pushing member 150 and the self-locking member 370 move relative to each other until the first side surface 153 and the second side surface 375 come into abutment. The pushing member 150 applies a pushing force to the self-locking member 370 to cause the self-locking member 370 to elastically retreat, and the hook portion 378 is displaced relative to the pin 400. In combination with Figure 13 and Figure 16 , then the pushing member 150 and the self-locking member 370 move relative to each other until the first inclined surface 151 and the fourth inclined surface 374 come into abutment, so that the self-locking member 370 elastically resets, and the hook portion 378 catches the pin 400 to lock the position of the pin 400. Such a design realizes the locking after the pin 400 moves into place.

[0100] Alternatively, vice versa, when the transmission assembly 100 is in a sliding state and the accommodating cavity 240 changes from an open state to a partially open state, the pushing member 150 and the self-locking member 370 move relative to each other until the first side surface 153 abuts against the second side surface 375, so that the self-locking member 370 elastically retreats, and the hook portion 378 is displaced relative to the pin 400 to release the locking of the position of the pin 400; the pushing member 150 and the self-locking member 370 move relative to each other until the second inclined surface 152 abuts against the third inclined surface 373, and then they can continue to move so that the pushing member 150 is separated from the self-locking member 370, which is specifically similar to that described above and will not be elaborated here.

[0106] As an example, as Figure 2 and Figure 3 shown, the gear set assembly 300 includes a fixing bracket 340, a gear set 380, a bushing 350, etc., in combination with Figure 22 and Figure 23, the gear set 380 includes a first gear 310, a second gear 320, a third gear 330, a first shaft 311, a second shaft 321, and a third shaft 331; the fixed bracket 340 is provided with a first hole 341, a second hole 342, a third hole 343, a fourth hole 344, a fifth hole 345, and a gear receiving cavity 349; during assembly, first place the first gear 310 into the gear receiving cavity 349, and the first shaft 311 sequentially passes through the two second holes 342 on the left, the first gear 310, and the two second holes 342 on the right, and the second gear 320 is fixed to the fixed bracket 340 through the interference fit between the first shaft 311 and the second hole 342; then place the second gear 320 into the gear receiving cavity 349, and the second shaft 321 sequentially passes through the fourth hole 344 on the left, the second gear 320, and the fourth hole 344 on the right, and the second gear 320 is fixed to the fixed bracket 340 through the interference fit between the second shaft 321 and the fourth hole 344; finally, install the third shaft 331 on the third gear 330, the left and right sides of the third gear 330 are respectively sleeved with pins 400, then place the third gear 330 into the gear receiving cavity 349, and finally pass a bushing 350 through the fifth hole 345 on the left and sleeve it on the left end of the third shaft 331, and pass another bushing 350 through the fifth hole 345 on the right and sleeve it on the right end of the third shaft 331, so that the third gear 330 and the pins 400 are fixed to the fixed bracket 340 through the interference fit between the bushing 350 and the fifth hole 345; the gear set assembly 300 further includes an elastic member 360, a self-locking member 370, a spring shaft 361, and a fourth shaft 371; during assembly, the fixed bracket 340 is provided with a first hole 341 and a third hole 343, first place the elastic member 360 and the self-locking member 370 into the left spring receiving cavity 362 and the self-locking member receiving cavity 348 respectively, then the spring shaft 361 sequentially passes through the first hole 341 on the left, the elastic member 360, the sixth hole 376 on the self-locking member 370, and another first hole 341, and then the fourth shaft 371 sequentially passes through the third hole 343 on the left, the seventh hole 377 on the self-locking member 370, and then passes through another third hole 343 on the left, so that the elastic member 360 and the self-locking member 370 are fixed to the left side of the fixed bracket 340 through the interference fit between the spring shaft 361 and the first hole 341, and the interference fit between the fourth shaft 371 and the third hole 343. The assembly of the elastic member 360 and the self-locking member 370 on the right side is the same as above and will not be elaborated.

[0107] As an example, such as Figure 10 and Figure 12As shown, a bending portion 121 is provided on the sliding plate 120 of the transmission assembly 100, and a sliding track 141 is provided on the sliding track frame 140; during assembly, the bending portion 121 is disposed in the sliding track 141, and the bending portion 121 can slide in the sliding track 141, so that the sliding plate 120 can slide in the sliding track 141 of the sliding frame 140, and further enables the sliding cover 110 to slide left and right in the illustrated direction relative to the housing assembly 200 of the adapter 900.

[0108] As an example, when the transmission assembly 100 is in its original state, i.e., the initial state, the rack 131 engages with the first gear 310 on the gear set 380 or does not contact the first gear 310. At this time, the accommodation cavity 240 is in a closed state, and the sliding cover 110 covers the pins 400, playing a role in protecting the pins 400; combined Figure 3 , Figure 6 , Figure 9 and Figure 15 , when the sliding cover 110 of the transmission assembly 100 starts to slide left in the illustrated direction, after sliding a certain distance, when the rack 131 starts to engage with the first gear 310, the rack 131 drives the first gear 310 to rotate, the first gear 310 drives the second gear 320 to rotate, and the second gear 320 drives the third gear 330 to rotate, thereby driving the pins 400 on the shaft of the third gear 330 to rotate counterclockwise, thus starting to open the pins 400, that is, adjusting the pins 400 from the received state to the open state; after the sliding cover 110 continues to slide a certain distance, when the rack 131 disengages from the first gear 310, at this time the pins 400 are completely open, that is, the included angle with the adapter housing is 90 degrees, and at this time the pins 400 can be inserted into an appropriate socket; combined with Figure 1 , Figure 5 , Figure 8 and Figure 14 , when the pins 400 are to be received, the sliding cover 110 slides right in the illustrated direction. When the rack 131 starts to engage with the first gear 310, the rack 131 drives the first gear 310 to rotate, the first gear 310 drives the second gear 320 to rotate, and the second gear 320 drives the third gear 330 to rotate, thereby driving the pins 400 on the shaft of the third gear 330 to start rotating clockwise, thus starting to receive the pins 400, and at this time the sliding cover 110 completely covers the pins 400.

[0109] As an example, a pushing member 150 is provided on the sliding cover 110 of the transmission assembly 100. The pushing member 150 is provided with a first inclined surface 151, a second inclined surface 152 and a first side surface 153. A self-locking member 370 is provided on the gear set assembly 300. The self-locking member 370 is provided with a protrusion 372 and a hook portion 378. The protrusion 372 is provided with a third inclined surface 373, a fourth inclined surface 374 and a second side surface 375. When the transmission assembly 100 is in the original state, i.e., the initial state, the sliding cover 110 is disposed on the housing assembly 200 and the accommodating cavity 240 is in a closed state. There is a certain distance between the pushing member 150 and the self-locking member 370. At this time, the sliding cover 110 covers the pin 400, playing a role in protecting the pin 400. When the sliding cover 110 of the transmission assembly 100 starts to slide, as shown in the figure as sliding to the left, after the sliding cover 110 slides a certain distance, the second inclined surface 152 on the pushing member 150 starts to abut against the third inclined surface 373 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110, the pushing member 150 applies a certain force to the self-locking member 370, causing the pushing member 150 to move away from the gear set 380 and the self-locking member 370 to compress the elastic member 360. Thus, the first side surface 153 on the pushing member 150 cooperates with the second side surface 375 on the protrusion 372 of the self-locking member 370. After sliding a certain distance, the first side surface 153 on the pushing member 150 separates from the second side surface 375 on the protrusion 372 of the self-locking member 370. At this time, the elastic member 360 resumes its original state, and the first inclined surface 151 on the pushing member 150 abuts against the fourth inclined surface 374 on the protrusion 372 of the self-locking member 370. At this time, the hook portion 378 on the self-locking member 370 hooks the pin 400, completing the self-locking of the pin 400. When unlocking is required, when the sliding cover 110 starts to slide to the right, the first inclined surface 151 on the pushing member 150 starts to abut against the fourth inclined surface 374 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110 of the transmission assembly 100, the pushing member 150 applies a certain force to the self-locking member 370, causing the pushing member 150 to move away from the gear set 380 and the self-locking member 370 to compress the elastic member 360. Thus, the unlocking of the pin 400 is completed. At this time, the first side surface 153 on the pushing member 150 cooperates with the second side surface 375 on the protrusion 372 of the self-locking member 370. After sliding a certain distance, the first side surface 153 on the pushing member 150 separates from the second side surface 375 on the protrusion 372 of the self-locking member 370. At this time, the elastic member 360 resumes its original state, and the second inclined surface on the pushing member 150 abuts against the third inclined surface 373 on the protrusion 372 of the self-locking member 370. Continuing to slide the sliding cover 110 until the sliding cover 110 slides to the original state to cover the pin 400, as Figure 4 , Figure 7 , Figure 13 and Figure 5 shown

[0110] With such a structural design, the user can open and fold the plug pins 400 with one hand, which is more convenient to use. The sliding cover can better protect the plug pins 400 and prevent foreign objects or dirt on the plug pins 400 from affecting their electrical performance. After the plug pins 400 are opened, they are self-locked through a self-locking mechanism to ensure that the plug pins 400 will not tilt during the process of inserting the plug pins 400 into the socket strip or socket.

[0111] It should be noted that other embodiments of the present application also include an adapter formed by combining the technical features in the above embodiments and capable of being implemented.

[0112] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0113] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
