Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

The following disclosure provides many different embodiments, or examples, for implementing different structures of the disclosure. In order to simplify the present disclosure, components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present disclosure. Furthermore, 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 will recognize the applicability of other processes and/or the use of other materials.

With more and more electronic devices used in daily life, such as smartphones, tablet computers, etc., power adapters for charging electronic devices are used more frequently, however, the power adapters in the related art have a large overall size and are inconvenient to carry and store. In order to solve 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: the power pin 3 is arranged on the rotating shaft piece 2 and rotates synchronously with the rotating shaft piece 2. 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 member 2 rotates to the first angular position, the elastic member 1 extends and vertically abuts against the first flat portion 211, and the power pin 3 reaches the working position.

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

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 pin 3 reaches the storage position.

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

Thus, the power pin 3 can be stably held at the operating position and the storage position by the engagement of the elastic member 1 and the protruding portion 21, and the operational reliability and the storage reliability of the power pin 3 can be provided. In addition, since the elastic member 1 applies a reaction force to the rotating shaft member 2 when the rotating shaft member 2 rotates, in the process of opening or folding the power pin 3, the elastic force pushing the elastic member 1 needs to be overcome, and the elastic member 1 provides a certain damping, so that the folding assembly 100 is improved in folding and unfolding handfeel experience.

In summary, according to the power adapter 1000 of the embodiment of the present disclosure, the protrusion 21 is designed on the rotating shaft member 2 connected to the power pin 3, when the power pin 3 is folded and stored or unfolded, the protrusion 21 pushes the elastic member 1 to deform in a telescopic manner, so that the service life of the power adapter 1000 of the embodiment of the present disclosure is long, the elastic member 1 can be utilized to improve the feel of folding and unfolding, and meanwhile, the elastic member 1 cannot have fatigue failure or weakening problem due to long service time, and in addition, the folding assembly 100 is simple in structure, the occupied space of the power pin 3 after folding and storing is small, for example, in some embodiments, the folding assembly 100 only needs to occupy 21.4mm of space in length space, while the related art needs to occupy 23-25 mm of space, compared with the related art, which is very convenient for storing.

In short, according to the power adapter 1000 of the embodiment of the present disclosure, with the cooperation of the projection 21 and the elastic member 1, the folding movement of the power pins 3 can be achieved, thereby realizing the design of the miniaturized power adapter 1000. Alternatively, the power pins 3 can be folded and stored reliably, 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 disposed orthogonally, that is, the first flat portion 211 and the second flat portion 212 are perpendicular to each other. Therefore, the angles of the first flat portion 211 and the second flat portion 212 are easy to measure, so that the processing of the protruding portion 21 is facilitated, the production efficiency is improved, and the position of the power pin 3 can be simply and effectively controlled.

The surfaces of the first flat portion 211 and the second flat portion 212 may be planar or non-planar, for example, some concave holes or protrusions may be formed on the surfaces, so long as the surfaces of the first flat portion 211 and the second flat portion 212 are substantially planar, thereby facilitating the processing, reducing the rotation resistance of the shaft member 2, saving the operation effort, and enabling the power pin 3 to stay in the working position and the storage position more reliably.

For example, in the examples 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, 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 the user inserts the power adapter 1000 onto the power source (for example, the power strip, the socket, etc.), the power pin 3 is not easy to turn to the storage side, so that the user can operate conveniently.

For example, in the examples 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, 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 user cannot easily turn over the power pin 3 to the working side during the storage process, so that the user can store conveniently.

In some embodiments, as shown in fig. 2, the first flat portion 211 and the second flat portion 212 may be connected by a smooth transition of curved surfaces. Therefore, when the power pin 3 rotates to a position where the first flat portion 211 is connected to the second flat portion 212 (for example, a position shown in fig. 6), a jam is not easy to occur, so that the power pin 3 rotates smoothly, and the operation of a user is facilitated.

In some embodiments, as shown in fig. 1, the folding assembly 100 may further include: the first housing 4, the first housing 4 has therein a housing cavity 41, the surface of the first housing 4 has an escape groove 42 communicating with the housing cavity 41, and when the power pin 3 reaches the housing position, the end of the power pin 3 (the end of the power pin 3 away from the shaft member 2) protrudes out of the escape groove 42, and the portion of the power pin 3 other than the end is housed in the housing cavity 41 and the escape groove 42, as shown in fig. 8.

Therefore, when the power pin 3 is in the storage position, only the end part of the power pin 3 can be exposed, at this time, the power adapter 1000 is small in size and convenient to store, and in addition, when the power pin 3 needs to be folded from the storage position to the working position, a user can rotate the power pin 3 to the working position by pushing the exposed part of the power pin 3, so that the power pin 3 is easy to operate when being folded.

Of course, the disclosure is not limited thereto, for example, in some embodiments, when the power pin 3 is located in the storage position, a groove may be formed on the first housing 4 at the end position of the power pin 3, where the power pin 3 will not be visible in the side projection of the power adapter 1000, and the user may contact the power pin 3 at the groove position for folding, etc. when using the power adapter, which will not be described herein. In addition, when the power pin 3 reaches the working position, at least most of the power pin 3 can extend out of the avoidance groove 42, so that the plugging 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 include: the first bracket 5, the first bracket 5 defines a sliding groove 51 extending along the first direction F1, one end of the sliding groove 51 in the first direction F1 is opened to form a sliding groove opening 511, and the elastic member 1 is matched with the sliding groove 51. Thereby, the working space of the elastic member 1 can be defined by the first bracket 5, for example, when the elastic member 1 is elastically deformed due to the stress, the elastic member 1 does not run out of the first bracket 5 and deforms other than stretches, 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 include: the sliding block 6, the sliding block 6 is slidably matched with the sliding groove 51, and the sliding block 6 is positioned on 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 protruding part 21.

Therefore, the slider 6 is located between the protruding portion 21 and the elastic member 1, when the power pin 3 is folded, the protruding portion 21 can push the slider 6 to slide along the first direction F1 in the sliding groove 51, and at this time, the protruding portion 21 cannot be in direct contact with the elastic member 1, so that the problems of mutual locking 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, by providing the first bracket 5, the sliding reliability of the slider 6 can also be improved.

In some embodiments, as shown in fig. 1 and 3, the other end of the sliding groove 51 in the first direction F1 is closed as a chute ceiling 512. Therefore, one end of the elastic element 1, which is close to the sliding groove top plate 512, can be abutted against the sliding groove top plate 512, when the power pin 3 is folded, the elastic element 1 can be abutted against the sliding groove top plate 512 all the time, and the sliding groove top plate 512 provides a reaction force, so that the influence of the structural shape of the shell of the power adapter 1000 is avoided, and the working reliability and the application range of the elastic element 1 can be ensured.

Of course, the disclosure is not limited thereto, and for example, in a specific embodiment, the chute top plate 512 may be omitted, for example, where the elastic member 1 may directly abut against the first housing 4, which is not limited herein. In addition, the type of the elastic member 1 is not limited, and may be, for example, a cylindrical spring, a belleville spring, etc., and will not be described here. For example, in some embodiments, as shown in fig. 3, the elastic member 1 may be a cylindrical spring and disposed opposite to the center of the rotating shaft member 2. Thus, the generated force can be applied to 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 in manufacture and low in production cost, and meanwhile, fatigue or weakening of hand feeling of the cylindrical spring is not easy to occur due to long service time.

In some embodiments, as shown in fig. 1 and 3, the folding assembly 100 may further include: the rotating shaft piece 2 is rotatably matched with the second support 7, and the electric connecting piece 8 penetrates through the second support 7 and is electrically connected with the power pin 3. Therefore, the second bracket 7 can support the rotating shaft member 2 to rotate, and meanwhile, the power receiving member 8 is electrically connected with the power pin 3, and the power pin 3 is electrically connected with other circuit components (for example, a circuit module 200 described below) by penetrating the power receiving member 8 into the second bracket 7, so that the folding component 100 is compact in structure and high in working reliability.

In some embodiments, as shown in fig. 10, the shaft member 2 may include: the two shaft portions 22, the shaft seat portions 23 and the power connection portions 24 are respectively arranged at two axial ends of the shaft portion 22, the two power connection portions 24 are respectively arranged at two sides of the two shaft portions 23, the protruding portions 21 are arranged on the outer peripheral surface of the shaft portion 22, each shaft portion 23 is respectively provided with one power pin 3, one end, away from the shaft portion 23, of the power connection portion 24 is provided with a power connection point electrically connected with the power pin 3, the second support 7 can be provided with two limiting grooves 71 and two inserting grooves 72, the two inserting grooves 72 are arranged at two sides of the two limiting grooves 71, the two shaft seat portions 23 are respectively rotatably matched with the two limiting grooves 71, the two power connection pieces 8 are respectively matched with the two inserting grooves 72, and are electrically connected with the power connection points on the power connection portions 24 at corresponding sides. Thus, the folding assembly 100 is compact and highly reliable in operation. In addition, in some embodiments, the power pin 3, the shaft portion 23, the middle shaft portion 22 and the power receiving portion 24 may be an integral piece formed by injection molding of embedded metal, which is not described herein.

For example, in one embodiment, the two electrical connectors 8 are respectively engaged with the two mating grooves 72, and the two shaft seat portions 23 are respectively engaged with the two limiting grooves 71, where each electrical connector 8 may be electrically connected to the corresponding power pin 3 through the electrical connection points on the electrical connection portions 24 at the two axial ends of the central shaft portion 22 on the corresponding side. Thus, the folding assembly 100 is compact and highly reliable in connection.

In some embodiments, as shown in fig. 10 and 3, a portion of the second bracket 7 located between the two limiting grooves 71 is a first supporting portion 73, and the central shaft portion 22 is rotatably supported on the first supporting portion 73. Thus, the first supporting portion 73 can support the middle shaft portion 22 to rotate, so that stability of the rotating shaft member 2 during rotation can be improved, and in addition, the power pin 3 receives a force extending in the extending direction of the power pin 3 when being inserted into the socket, at this time, the middle shaft portion 22 can be supported by the first supporting portion 73, damage of the middle shaft portion 22 when receiving a pressure (for example, when being inserted into the socket) can be avoided, and thus the service life of the middle shaft portion 22 can be prolonged.

In some embodiments, as shown in fig. 10 and 3, a portion of the second bracket 7 between the limiting groove 71 and the insertion groove 72 on the corresponding side is a second supporting portion 74, and the power receiving portion 24 is rotatably supported on the second supporting portion 74. Thus, the second supporting portion 74 can support the power receiving portion 24 to rotate, so that stability of the rotating shaft member 2 in the rotating process can be improved, and in addition, when the power pin 3 is inserted into the socket, a force along the extending direction of the power pin 3 can be received, at this time, the power receiving portion 24 can be supported by the second supporting portion 74, and damage to the power receiving portion 24 can be avoided.

In some embodiments, as shown in fig. 10 and 3, a portion of the second bracket 7 located on a side of the mating groove 72 away from the limiting groove 71 is a stopper portion 75, and the power receiving member 8 includes a spring plate portion 81 that is sandwiched between the power receiving portion 24 and the stopper portion 75. Therefore, one side of the spring plate portion 81 can be abutted against the stop portion 75, and the other side is in contact with the power receiving portion 24, at this time, the contact between the power receiving portion 24 and the spring plate portion 81 can be more compact, so that the current can flow smoothly, stably and reliably.

For example, in the specific example shown in fig. 10, the electrical connector 8 may further include a flange portion 82, and in combination with fig. 3, when the electrical connector 8 is connected with the mating groove 72 in a mating manner, one side of the elastic sheet portion 81 in the electrical connector 8 contacts the electrical connector 24, and the other side of the elastic sheet portion abuts against the stop portion 75, and at this time, the flange portion 82 may abut against the bottom surface of the stop portion 75, so that displacement of the electrical connector 8 relative to the stop portion 75 may be avoided, and thus, structural stability when the second bracket 7 is connected with the electrical connector 8 may be improved.

In some embodiments, as shown in fig. 1, the folding assembly 100 may further include: the first housing 4 has a housing chamber 41 in the first housing 4, one end of the housing chamber 41 in the first direction F1 is opened as a mounting port 411, and the second bracket 7 is fitted in the housing chamber 41 through the mounting port 411. Thereby, the second bracket 7 can be fitted and fixed in the accommodation cavity 41 in the first housing 4, so that the first housing 4 can protect the second bracket 7, and thus the service life of the second bracket 7 can be increased.

In some embodiments, as shown in fig. 1, the power adapter 1000 may further include: the second housing 300, referring to fig. 4, the second housing 300 is assembled and connected with the first housing 4, and covers the mounting opening 411, and the circuit module 200 of the power adapter 1000 is received in the second housing 300 and electrically connected with the power pins 3 through the power connector 8. Thus, the second housing 300 can house the circuit module 200 therein, the first housing 4 can house the folding assembly 100 therein, the circuit module 200 is electrically connected to the power pins 3 through the power connector 8, and when the power pins 3 are plugged into, for example, a socket, an electric current can flow from the power pins 3 to the circuit module 200 in the second housing 300.

In some specific examples of the present disclosure, as shown in fig. 14, a USB interface 2001 may also be formed on the second housing 300 to communicate with the circuit module 200 to facilitate the user in connecting the data line to the power adapter 1000. In addition, when the first housing 4 and the second housing 300 are assembled, the first housing 4 and the second housing 300 may be connected together by, for example, heat fusion, ultrasonic welding, or the like, so that the structural strength of the first housing 4 and the second housing 300 may be increased, thereby improving the structural stability of the power adapter 1000 and increasing the service life of the power adapter 1000. Of course, the present disclosure is not limited thereto, and the first housing 4 and the second housing 300 may be detachably assembled and connected.
