detailed description

The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present disclosure, but should not be construed as limiting the present disclosure.

The following disclosure provides many different embodiments or examples for realizing different structures of the present disclosure. In order to simplify the disclosure of the present disclosure, components and settings of specific examples are described below. Of course, they are only examples, and are not intended to limit the present disclosure. In addition, the present disclosure may repeat reference numerals and/or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not in itself indicate the relationship between the various embodiments and/or settings discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and/or the use of other materials.

As more and more electronic devices are used in daily life, such as smart phones, tablet computers, etc., power adapters for charging electronic devices are also used more frequently. However, the overall volume of power adapters in related technologies is relatively large. Easy to carry and store. In order to solve at least one of the above technical problems, the present disclosure provides a power adapter 1000.

Hereinafter, referring to the drawings, a power adapter 1000 according to an embodiment of the present disclosure will be described.

As shown in Figure 1, the power adapter 1000 may include a folding assembly 100, which may include: a mounting frame 1 and two pins 2. The mounting frame 1 has two sliding grooves 11, and the length of each pin 2 is at both ends. Is the sliding end 2a and the power connection end 2b. The two sliding ends 2a are respectively fitted to the two sliding grooves 11 (for example, the sliding end 2a of the pin 2 on the left side shown in FIG. The sliding groove 11 is matched, and the sliding end 2a of the pin 2 on the right is matched with the sliding groove 11 on the right). With reference to Fig. 2, the two pins 2 are foldable between the plug-in state (combined with Fig. 3) and the storage state (combined with Fig. 4).

In the plug-in state, the two pins 2 are erected (that is, the center lines of the two pins 2 are parallel, for example, the two pins 2 are located at the position A shown in Figure 2), and the two sliding ends 2a are respectively located in the two sliding grooves 11 One end 11w far away from each other. That is, when the two sliding ends 2a move away from each other along the corresponding sliding groove 11, the two power-connecting ends 2b are close to each other, so that the two pins 2 switch toward the plug-in state (for example, the state shown in FIG. 3). For example, in the specific example shown in FIG. 2, when the two sliding ends 2a are far away from each other, the electrical terminals 2b of the two pins 2 are close to each other, as shown in FIG. 2 when the two pins 2 are located at the position A shown in the figure. , The two pins 2 are parallel to each other, combined with Figure 3, it is convenient to plug the power adapter 1000 into a power source (such as a socket, a power strip, etc.). At this time, it can be in the plug-in state or the position of the pin 2 in the plug-in state, and, At this time, the distance between the roots of the two pins 2 (that is, the sliding end 2a) is relatively large, which can easily meet the requirements of safety regulations, and the safety is higher.

In the storage state, the two pins 2 are flattened (that is, the center lines of the two pins 2 are coplanar, for example, the two pins 2 are located at the position C shown in Figure 2), and the two sliding ends 2a are respectively located in the two sliding grooves 11 One end 11n close to each other. That is to say, when the two sliding ends 2a approach each other along the corresponding sliding groove 11, the two electrical connection ends 2b move away from each other, so that the two pins 2 are switched toward the storage state (for example, the state shown in FIG. 4). For example, in the specific example shown in FIG. 2, when the two sliding ends 2a are close to each other, the electrical connection ends 2b of the two pins 2 gradually move away from each other, and reach the position shown in the figure through the position B shown in FIG. At position C, when the pin 2 reaches the C position, the two pins 2 are substantially coplanar (for example, the insert part 21 of the pin 2 described later is coplanar). With reference to FIG. 4, the pin 2 can be in a stowed state, which is convenient for storage. Moreover, at this time, the distance between the roots of the two pins 2 (that is, the sliding end 2a) is relatively small, so that the space occupied by the width of the power adapter 1000 can be saved.

As a result, the two pins 2 can be switched between the plug-in state and the storage state simply, quickly, and effectively. Moreover, during the folding process of the two pins 2 from the working position to the storage position, the roots of the two pins 2 (that is, the sliding end 2a) can gradually approach, so when the two pins 2 reach the storage position, more space can be saved For example, when the power pin 2 reaches the storage position, it can extend along the width direction of the power adapter 1000, so that the space occupied by the width of the power adapter 1000 can be saved. Moreover, since the two pins 2 are folded from the storage position to the working position, the roots (that is, the sliding ends 2a) of the two pins 2 are far away from each other. Therefore, when the two pins 2 reach the plug-in state, the two pins 2 The distance between the roots (that is, the sliding end 2a) can easily meet the requirements of safety regulations, and the safety is higher.

According to the power adapter 1000 of the embodiment of the present disclosure, the pins 2 can be reliably folded, stored, and unfolded, and the volume when folded to the storage state is small, and the safety and reliability when folded to the plug-in state are high, so that the power adapter 1000 has a small volume , Easy to carry and store, and high work safety. In addition, the folding assembly 100 has a simple structure, is convenient for processing and production, and has a low cost.

In some embodiments, as shown in FIGS. 5 and 6, the sliding groove 11 may be an arc-shaped sliding groove 11a, the sliding end 2a has a flat shaft section 231, and the flat shaft section 231 is slidably and non-rotatably fitted to the arc. The sliding groove 11a enables the pin 2 to rotate around the axis of the center point of the sliding groove 11 to achieve folding. In other words, the flat shaft section 231 can only move along the arc-shaped sliding groove 11a and cannot rotate around the central axis of the flat shaft section 231 itself. As a result, the working reliability of the folding assembly 100 when folded can be improved. In this way, according to the power adapter 1000 of the embodiment of the present disclosure, when the power connection end 2b of the pin 2 is turned outward by an external force, the sliding end 2a of the pin 2 will rotate along the arc-shaped sliding groove 11a, and the pin 2 will slide at the same time. The end 2a will move closer to the center to achieve flattening and folding, thereby minimizing the width and saving space. When the external force pushes the connecting end 2b of the pin 2 to stand up toward the center, the sliding end 2a of the pin 2 will rotate along the arc-shaped sliding groove 11a, and the sliding end 2a of the pin 2 will slide outward to achieve vertical movement. When folded, the pin 2 can be in the plug-in state, and the distance between the sliding ends 2a of the two pins 2 is relatively large, and the safety distance meets the requirements.

In some embodiments, as shown in FIG. 7, the two pins 2 can be synchronously rotated in the reverse direction through the linkage assembly 4a, so that the two pins 2 can be rotated in the reverse direction at the same time, and the two pins 2 can be folded synchronously. Therefore, when only one pin 2 is pushed, the two pins 2 can be folded to the use position or the storage position, which is convenient for the user to operate, and the operation is time-saving and labor-saving. In addition, the folding assembly 100 has a simple mechanism, a small volume, and high reliability of action.

In some embodiments, as shown in FIG. 7, the linkage assembly 4a includes two meshing wheels 4 rotatable about its own central axis. The two meshing wheels 4 mesh with each other and respectively correspond to the two pins 2, so that the two Pin 2 moves in the reverse direction synchronously. That is to say, the linkage assembly 4a may include two meshing and cooperating meshing wheels 4, the two meshing wheels 4 mesh with each other, and each meshing wheel 4 is rotatable relative to the mounting frame 1 about the center axis of the corresponding meshing wheel 4, and the two meshing wheels 4 The sliding portion 23 of the pin 2 is also matched with the two meshing wheels 4 respectively. For example, the pin 2 on the left side shown in FIG. 7 can be matched with the meshing wheel 4 on the left, and the pin 2 on the right can be matched with the right side. The meshing wheels 4 are matched, and at the same time, the two meshing wheels 4 mesh with each other, so that the two pins 2 can move synchronously and reversely.

Thus, any one pin 2 of the two pins 2 can move, which can drive the two meshing wheels 4 to reversely mesh and rotate, and when the two meshing wheels 4 mesh and rotate, it can drive the other pin 2 to move synchronously and reversely. . Wherein, the two meshing wheels 4 rotate in opposite directions. For example, when one of the meshing wheels 4 rotates clockwise, the other meshing wheel 4 rotates counterclockwise. Therefore, only one of the pins 2 can be pushed to realize the simultaneous reverse rotation of the two pins 2 to complete the folding of the pin 2. For example, pushing the pin 2 makes the pin 2 fold to the use position or the storage position, which is convenient for the user to operate and fold. The component 100 has a simple structure and high working reliability.

In some embodiments, as shown in FIG. 8, the meshing wheel 4 may have a groove 41 extending in the radial direction of the meshing wheel 4. With reference to FIG. 9, the sliding portion 23 is slidably fitted to the groove 41 to The meshing wheel 4 is linked with the corresponding pin 2. Therefore, when the sliding part 23 slides in the groove 41, since the meshing wheel 4 can only rotate, when the position of the sliding part 23 in the groove 41 also changes, it will drive the meshing wheel 4 to rotate. As a result, the mating linkage of the meshing wheel 4 and the pin 2 can be realized simply and effectively, so that the folding assembly 100 has a simple structure, is easy to process and assemble, and has high working reliability.

In some embodiments, as shown in FIG. 9, the sliding end 2 a includes a circular shaft section 232, and the circular shaft section 232 is slidably and rotatably fitted to the channel 41. That is to say, when the round shaft section 232 is matched with the groove 41, it can slide while rotating, so that the folding action can be performed smoothly. As a result, the smoothness of the engagement between the meshing wheel 4 and the sliding portion 23 can be improved.

In some embodiments, as shown in FIG. 9, the sliding portion 23 may include a flat shaft section 231 and a round shaft section 232. The flat shaft section 231 extends along the width direction of the insert portion 21, and the flat shaft section 231 extends two The ends respectively extend beyond the width side surfaces of the insert part 21 (as shown in Figure 6). The round shaft section 232 is arranged at the extended end 231a of the flat shaft section 231 and cooperates with the groove 41. The flat shaft section 231 is far away from the round shaft. The other extending end 231b of the segment 232 is matched with the sliding groove 11. Therefore, the flat shaft section 231 can only slide in the slide groove 11 when the flat shaft section 231 is matched with the chute 11, and the round shaft section 232 can slide while rotating when the round shaft section 232 is matched with the groove 41, so that the folding action can be performed smoothly.

It should be noted that the cross-sectional shape of the flat shaft section 231 can be an oblong or elliptical shape, and for example, it can also be other shapes that can be matched with the arc of the sliding groove 11, such as a fan shape, a rectangle, etc., as long as the flat shaft section 231 can be made. It only needs to move along the arc-shaped chute 11a and not rotate around the central axis of the flat shaft section 231 itself, which is not limited here. In addition, it should be noted that the oblong circle refers to: a semicircle, or racetrack shape, is set at both ends of the length of the rectangle.

In some embodiments, as shown in FIGS. 5 and 6, the pin 2 may include an insert part 21, a bent part 22, and a sliding part 23. The bent part 22 is defined by one end of the length of the insert part 21 (for example, FIG. 5 The lower end 21a of the inserting piece portion 21 shown is bent, and the sliding portion 23 is provided at the end of the bent portion 22 away from the inserting piece portion 21 (for example, the end 22a of the bent portion 22 shown in FIG. 5) , So that the two ends of the bent portion 22 are respectively connected to the inserting piece portion 21 and the sliding portion 23, and the sliding portion 23 can be used as the sliding end 2a to cooperate with the sliding groove 11.

As a result, the structure of the pin 2 is simple, which is convenient for production and processing, so that the production efficiency can be improved. In addition, in conjunction with FIG. 2, by providing a bent portion 22 on the pin 2, it can be made that when the pin 2 is in the storage position (as shown in FIG. 2 at position C), the position of the insert portion 21 is higher than the position of the chute 11 , So that the mounting frame 1 defining the sliding groove 11 can be housed in the housing 3 described later, but the pins 2 are exposed outside the housing 3, so that the structure of the power adapter 1000 is more compact and compact.

For example, in the specific embodiment shown in FIG. 5, the insert part 21 in the pin 2 is a flat plate, and the flat plate is bent at one end 21a of the length direction of the pin 2 to form a bent part 22, and the other end 22a of the bent part 22 A sliding part 23 is provided, and the sliding part 23 can cooperate with the sliding groove 11 and can move along the sliding groove 11. As a result, the structure of the pin 2 is simple, which is convenient for production and processing, so that the production efficiency can be improved. In addition, when the sliding part 23 is matched with the sliding groove 11, the moving range of the sliding part 23 can be limited by the sliding groove 11, so that the sliding part 23 will not move outside the sliding groove 11 when the pin 2 is folded, thereby improving The working reliability of the folding assembly 100.

In some embodiments, as shown in FIG. 1, the folding assembly 100 may further include a housing 3 with a containing cavity 311 in the housing 3, a groove 312 is provided on the outer surface of the housing 3, and a communication is provided on the housing 3 In the receiving cavity 311 and the perforation 313 of the sink 312, the mounting frame 1 is installed in the receiving cavity 311 (as shown in FIG. 10), and the pin 2 is inserted through the perforation 313, so that the pin 2 can be removed from the housing 3 through the perforation 313. The inside passes out to the outside of the housing 3 to be plugged into the power source.

In the storage state, the insert part 21 is received in the sink groove 312, and the electrical connection terminal 2b is located outside the sink groove 312 (as shown in FIG. 4). It can be understood that when the pin 2 of the power adapter 1000 is folded to the storage position, the volume of the power adapter 1000 is small, and at this time, it is convenient for the user to store it. In addition, when the pin 2 needs to be folded from the storage position to the working position, the power terminal 2b exposed outside the sink groove 312 can be pushed to fold the pin 2 to the working position (as shown in Figure 3). At this time, the two pins 2 Extend in a direction perpendicular to the surface of the sink groove 312 and away from the sink groove 312, so that it is convenient for users to use.

In some specific examples, the sink groove 312 may be formed on one side surface in the thickness direction of the housing 3. As a result, the space occupied by the pins 2 in the length and width directions of the power adapter 1000 can be further reduced.

In some embodiments, as shown in FIG. 1, the mounting frame 1 may also have two rotating shafts 12. In combination with FIG. 7, the two rotating shafts 12 are respectively penetrated through the two meshing wheels 4, so that the meshing wheels 4 are opposed to each other. The mounting frame 1 is rotatable. Thus, the positions of the two meshing wheels 4 can be defined by the two rotating shafts 12, so that the two meshing wheels 4 can always maintain the meshing state when rotating, so that the working reliability of the folding assembly 100 can be improved. In addition, by arranging the rotating shaft 12 on the mounting frame 1, the structure of the folding assembly 100 is more compact and the assembly is more convenient, which is beneficial to the miniaturized design of the power adapter 1000.

It should be noted that when the rotating shaft 12 passes through the two meshing wheels 4, in order to meet the mating relationship when the two meshing wheels 4 mesh and rotate, it is necessary to provide a through hole 42 on the meshing wheel 4 according to the actual situation, for example, in FIGS. 8 and In the specific example shown in FIG. 9, the meshing wheel 4 is circular, so the through hole 42 is set at the center of the meshing wheel 4. The two meshing wheels 4 can be respectively sleeved on the two rotating shafts 12 on the corresponding side, so that the two The two meshing wheels 4 can mesh and cooperate.

In some embodiments, as shown in FIG. 1, the folding assembly 100 may further include a casing 3. It should be noted that the casing 3 described in this paragraph may be the above-mentioned casing 3 or not. The housing 3, for example, when it is not the housing 3 described above, the surface of the housing 3 may also not have a counter groove 312. When the pin 2 is in the storage position, the pin 2 is exposed outside the housing 3. Regardless of whether the housing 3 described in this paragraph is the housing 3 described above, the housing 3 described in this paragraph may include: a first housing portion 31 and a second housing portion 32, and the first housing portion 31 has The containing cavity 311 and the avoiding groove 314, the first shell portion 31 has a through hole 313 communicating with the containing cavity 311, the mounting frame 1 and the engaging wheel 4 are both arranged in the containing cavity 311, and the rotating shaft 12 is fitted to the avoiding groove 314 (combined 10), the pin 2 penetrates through the through hole 313, and the second shell portion 32 and the first shell portion 31 are assembled to cover the containing cavity 311. Thus, the components (such as the meshing wheel 4, the mounting frame 1, etc.) arranged in the containing cavity 311 can be protected by the housing 3, so that the service life of the folding assembly 100 can be increased. In addition, the structure of the folding assembly 100 is compact, which facilitates the miniaturization of the power supply adapter 1000.

It should be noted that the form in which the first shell portion 31 and the second shell portion 32 are assembled is not limited. For example, a detachable connection may be adopted, such as a bolt, a buckle, etc., to facilitate maintenance. For another example, it may be a non-detachable connection, such as heat melting, ultrasonic welding, etc., so as to increase the structural strength of the power adapter 1000, which will not be repeated here.

Hereinafter, referring to FIGS. 11-19, the specific actions of the pins 2 when they are folded will be briefly described.

As shown in Fig. 11, the two pins 2 are in the working position. In conjunction with Fig. 12, the flat shaft sections 231 of the two sliding parts 23 are far away from each other and are respectively located at the outer ends of the sliding grooves 11 on the corresponding sides (that is, away from the center of the mounting frame 1 13, the circular shaft sections 232 of the two sliding parts 23 are also far away from each other and are respectively located at the outer ends of the grooves 41 on the corresponding sides (ie, the edge positions far away from the center of the meshing wheel 4).

When the two pins 2 are folded to the storage position, the intermediate position shown in FIG. 14 is passed, in conjunction with FIG. 15. At this time, the flat shaft section 231 of the two sliding parts 23 is located in the middle position of the corresponding side sliding groove 11, in conjunction with FIG. , The circular shaft sections 232 of the two sliding parts 23 are located near the center of the meshing wheel 4 in the groove 41. During this process, the two sliding parts 23 gradually approach, and at the same time, the two sliding parts 23 gradually move toward the meshing wheel. 4 moves in the center direction.

Subsequently, the two pins 2 continue to be folded, and the two pins 2 can respectively reach the storage position (as shown in FIG. 17). At this time, as shown in FIG. 18, the flat shaft sections 231 of the two sliding parts 23 are close to each other and respectively. The inner end of the sliding groove 11 on the corresponding side (that is, the position close to the center of the mounting frame 1), in conjunction with FIG. 19, the circular shaft sections 232 of the two sliding parts 23 are also close to each other and are respectively located outside the groove 41 on the corresponding side During this process, the two sliding parts 23 continue to approach gradually, and at the same time, the two sliding parts 23 gradually move toward the edge of the engaging wheel 4.

It can be understood that when the power adapter 1000 needs to fold the pins 2 from the storage position to the working position, the above-mentioned action principle is the same but the action direction is opposite, and will not be repeated here.

In some embodiments, the folding assembly 100 may have an axisymmetric structure, so that the folding assembly 100 is easy to process, and can ensure the synchronization of the actions of the two pins 2 and the two meshing wheels 4 in linkage during operation. In addition, in some specific embodiments, as shown in FIGS. 20 and 21, the distance occupied by the width dimension D of the folding assembly 100 only needs to be slightly wider than the width of the housing 3 of the power adapter 1000, and the length dimension of the folding assembly 100 L1 occupies a relatively small distance in the length dimension L of the power adapter 1000. In addition, the thickness dimension W of the folding component may be equal to the thickness of the power adapter 1000. For example, in the specific examples shown in FIG. 20 and FIG. 21, the folding component 100 The width dimension D of the folding assembly 100 can be about 41.2mm, the length dimension L1 of the folding assembly 100 can be about 13mm, and the thickness dimension W of the folding assembly 100 is equal to the thickness of the power adapter 1000. Therefore, the folding assembly 100 occupies a relatively small space for the power adapter 1000 as a whole. Facilitate the miniaturization of the power adapter 1000. Other components of the power adapter 1000 according to the embodiment of the present disclosure, such as circuit modules, etc., and charging principles are known to those of ordinary skill in the art, and will not be described in detail here.
