Detailed Description

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be illustrative of the present disclosure, and should not be construed as limiting the present disclosure.

The following disclosure provides many different embodiments, or examples, for implementing different features of the disclosure. To simplify the disclosure of the present disclosure, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present disclosure. Further, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

With the increasing use of electronic devices in daily life, such as smart phones, tablet computers, and the like, power adapters for charging electronic devices are used more frequently, however, the overall size of the power adapter in the related art is large, and the power adapter is inconvenient to carry and store. To address at least one of the above technical problems, the present disclosure provides a power adapter 1000.

As shown in fig. 1, the power adapter 1000 may include a folding assembly 100. The folding assembly 100 may include: elastic component 1, pivot piece 2 and power pin 3, elastic component 1 is scalable deformation along first direction F1, and pivot piece 2 sets gradually along first direction F1 with elastic component 1, has bulge 21 on the pivot piece 2, and bulge 21 includes first flat portion 211 and the flat portion 212 of second, and power pin 3 establishes on pivot piece 2, and rotates with pivot piece 2 synchronous. As shown in fig. 2 and 3, the shaft member 2 is rotatable between a first angular position and a second angular position.

As shown in fig. 4 and 5, when the rotating shaft 2 rotates to the first angular position, the elastic member 1 extends and vertically abuts against the first flat portion 211, and the power pins 3 reach the working position.

As shown in fig. 6 and 7, in the process of rotating the rotating shaft member 2 from the first angular position to the second angular position, the protruding portion 21 first pushes the elastic member 1 to gradually shorten by the first flat portion 211, and then releases the elastic member 1 to gradually lengthen by the second flat portion 212.

As shown in fig. 8 and 9, when the rotating shaft member 2 reaches the second angular position, the elastic member 1 extends and vertically abuts against the second flat portion 212, and the power plug 3 reaches the receiving position.

As shown in fig. 6 and 7, in the process of rotating the rotating shaft member 2 from the second angular position to the first angular position, the protruding portion 21 first pushes the elastic member 1 to gradually shorten by the second flat portion 212, and then releases the elastic member 1 to gradually lengthen by the first flat portion 211.

Therefore, the power supply pin 3 can stably stay at the working position and the storage position by the cooperation of the elastic piece 1 and the convex part 21, and the working reliability and the storage reliability of the power supply pin 3 can be provided. In addition, because the elastic component 1 can exert the reaction force to the rotating shaft component 2 when the rotating shaft component 2 rotates, so that in the process of opening or folding the power pin 3, the elastic force for pushing the elastic component 1 needs to be overcome first, and a certain damping is provided by the elastic component 1, so that the hand feeling experience of the folding component 100 in folding and unfolding is improved.

In summary, according to the power adapter 1000 of the embodiment of the present disclosure, the protruding portion 21 is designed on the rotating shaft member 2 connected to the power pin 3, when the power pin 3 is folded, stored or unfolded, the protruding portion 21 can push the elastic member 1 to stretch and deform, and the elastic member 1 provides damping, so that the power adapter 1000 of the embodiment of the present disclosure has a long service life, the elastic member 1 can be used to improve the hand feeling of folding and unfolding, and meanwhile, the elastic member 1 does not have fatigue failure or weakened hand feeling due to long service time, and in addition, the structure of the folding assembly 100 is simple, and the occupied space after the power pin 3 is folded and stored is small, for example, in some embodiments, the folding assembly 100 only needs to occupy a space of 21.4mm in length space, while in related technologies, it needs to occupy a space of 23-25 mm, which is very convenient to store compared with related technologies.

In short, according to the power adapter 1000 of the embodiment of the present disclosure, the folding movement of the power pins 3 can be achieved by the cooperation of the protrusion 21 and the elastic member 1, thereby achieving the design of the miniaturized power adapter 1000. Or, the power pins 3 can be reliably folded and stored, so that the power adapter 1000 is small in size and convenient to carry and store. In addition, the power pin 3 has a simple structure, is convenient to process and produce, and has low production cost.

In some embodiments, as shown in fig. 2 and 3, the first flat portion 211 and the second flat portion 212 may be orthogonally disposed, that is, the first flat portion 211 and the second flat portion 212 are perpendicular to each other. Therefore, the angle between the first flat portion 211 and the second flat portion 212 can be easily measured, so that the processing of the protruding portion 21 is facilitated, the production efficiency is improved, and the position where the power supply pin 3 is present can be simply and effectively controlled.

It should be noted that the surfaces of the first flat portion 211 and the second flat portion 212 may or may not be flat, for example, there may be some concave holes or protrusions on the surfaces, and the surfaces of the first flat portion 211 and the second flat portion 212 may be substantially flat, so that the processing is convenient, the rotation resistance of the rotating shaft member 2 is small, the operation is labor-saving, and the power plug 3 can be reliably stopped at the working position and the storage position.

For example, in the example shown in fig. 4 and 5, when the power pin 3 reaches the working position, the power pin 3 extends along the second direction F2 perpendicular to the first direction F1, and at this time, when the power pin 3 reaches the working position, the elastic member 1 vertically abuts against the first flat portion 211, so that the power pin 3 can be fixed at the working position by the elastic member 1, and when a user plugs the power adapter 1000 to a power source (for example, a socket, etc.), the power pin 3 is not easily turned over to the receiving side, which is convenient for the user to operate.

For example, in the example shown in fig. 8 and 9, when the power pin 3 reaches the storage position, the power pin 3 extends along the first direction F1, and at this time, the power pin 3 reaches the storage position, and the elastic member 1 vertically abuts against the second flat portion 212, so that the power pin 3 can be fixed at the storage position by the elastic member 1, and the power pin 3 is not easily turned over to the working side during storage, which is convenient for the user to store.

In some embodiments, as shown in fig. 2, the first flat portion 211 and the second flat portion 212 may be connected by a curved smooth transition. Therefore, when the power pin 3 is rotated to a position where the first flat portion 211 and the second flat portion 212 are connected (for example, the position shown in fig. 6), the jamming is not easily generated, the rotation of the power pin 3 is smooth, and the operation by the user is convenient.

In some embodiments, as shown in fig. 1, the folding assembly 100 may further comprise: the first housing 4 has a housing chamber 41 in the first housing 4, and the first housing 4 has a bypass groove 42 communicating with the housing chamber 41 on the surface thereof, and referring to fig. 8, when the power supply pin 3 reaches the housing position, the end portion of the power supply pin 3 (the end of the power supply pin 3 remote from the shaft member 2) protrudes out of the bypass groove 42, and the portion of the power supply pin 3 other than the end portion is housed in the housing chamber 41 and the bypass groove 42.

Therefore, the power pins 3 can only expose the end parts of the power pins 3 when in the storage position, at the moment, the size of the power adapter 1000 is small, the storage is convenient, and in addition, when the power pins 3 need to be turned over from the storage position to the working position, a user can enable the power pins 3 to rotate to the working position by pushing the exposed parts of the power pins 3, so that the operation of the power pins 3 when turning over is simple.

Of course, the disclosure is not limited to this, for example, in some specific embodiments, when the power pins 3 are located at the storage position, a groove may also be provided on the first housing 4 at the end position of the power pins 3, at this time, the power pins 3 will not be seen in the side projection of the power adapter 1000, and when the user uses the power adapter, the user may contact the power pins 3 at the groove position to turn over, and so on, which is not described herein again. Furthermore, when the power supply pin 3 reaches the operating position, at least most of the power supply pin 3 may protrude out of the avoiding groove 42, so that the plug-in fit with the power supply can be conveniently realized.

In some embodiments, as shown in fig. 1 and 3, the folding assembly 100 may further comprise: the first bracket 5, the first bracket 5 defines a sliding slot 51 extending along the first direction F1, one end of the sliding slot 51 in the first direction F1 is opened as a sliding slot opening 511, and the elastic member 1 is fitted to the sliding slot 51. Therefore, the working space of the elastic member 1 can be limited by the first bracket 5, for example, when the elastic member 1 is elastically deformed by a force, the elastic member 1 does not go out of the first bracket 5 and is deformed except for extension and contraction, so that the structural stability and the working reliability of the folding assembly 100 can be improved.

In some embodiments, as shown in fig. 1 and 3, the folding assembly 100 may further comprise: the sliding block 6, the sliding block 6 can be glidingly matched with the sliding groove 51, the sliding block 6 is positioned at one side of the elastic piece 1 close to the sliding groove opening 511 so as to be clamped between the elastic piece 1 and the convex part 21.

Therefore, the slide block 6 is located between the protruding portion 21 and the elastic member 1, when the power plug 3 is folded, the protruding portion 21 can push the slide block 6 to slide in the sliding groove 51 along the first direction F1, at this time, the protruding portion 21 does not directly contact with the elastic member 1, so that the problems of mutual locking and the like of the elastic member 1 and the protruding portion 21 can be avoided, the reliability of the action is improved, and the service life of the folding assembly 100 can be longer. In addition, the sliding reliability of the sliding block 6 can be improved by arranging the first bracket 5.

In some embodiments, as shown in fig. 1 and 3, the other end of the sliding slot 51 in the first direction F1 is closed as the sliding slot top plate 512. From this, the one end that is close to spout roof 512 of elastic component 1 can end on spout roof 512, and elastic component 1 can begin to terminate when power is participated in 3 and support on spout roof 512, provides the reaction force by spout roof 512, does not receive the influence of power adapter 1000 shell structure shape to can guarantee the operational reliability and the application scope of elastic component 1.

In addition, the type of the elastic member 1 is not limited, and may be, for example, a cylindrical spring, a belleville spring, or the like, which will not be described herein. For example, in some embodiments, as shown in fig. 3, the elastic member 1 may be a cylindrical spring and is disposed opposite to the center of the shaft member 2. Therefore, the generated force can act on the center of the rotating shaft member 2 through the elastic deformation of the cylindrical spring, so that the stress of the rotating shaft member 2 is uniform, and the working stability of the folding assembly 100 can be improved. In addition, the cylindrical spring is simple to manufacture and low in production cost, and meanwhile, the cylindrical spring is not easy to fatigue or weaken in hand feeling due to long service time.
