Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

Due to the continuous development of electronic devices such as mobile phones, power adapters corresponding to the electronic devices are also continuously developed and advanced. The electronic device is usually provided with a rechargeable battery, and the power adapter usually comprises an adapter body and pins, when the pins are inserted into the socket, the power adapter and the electronic device are electrically connected through a charging wire, so that the rechargeable battery is charged.

At present, power adapter is developing towards the trend of miniaturization constantly, but the power adapter who constantly reduces can lead to participating in the edge that is close to adapter body and the continuous distance that reduces between adapter body's the periphery side, when being less than the certain distance, power adapter is at the in-process that charges this moment, when the user finger touches the periphery side, will lead to creepage distance short excessively, make on participating in the electric energy pass through adapter body and transmit the user finger, lead to the electric leakage, thereby cause the injury to the user. Therefore, there is a need for a power adapter that is small in size and can prevent current leakage.

In view of the above, in order to solve the above problems, the present application provides a novel power adapter. Referring to fig. 1 to 5, fig. 1 is a schematic diagram illustrating an application environment of a power adapter according to an embodiment of the present application. Fig. 2 is a schematic perspective view of a power adapter in a closed state according to an embodiment of the present application. Fig. 3 is a schematic perspective view illustrating a power adapter in an open state according to an embodiment of the present application. Fig. 4 is a schematic cross-sectional view of a power adapter with a portion of a cover opened according to an embodiment of the present disclosure. Fig. 5 is a partial schematic view of fig. 4. The present embodiment provides a power adapter 1, wherein the power adapter 1 has a closed state and an open state, and comprises an adapter body 10, a pin assembly 20, a cover body 30, and a flexible connecting member 40. The adapter body 10 has a receiving space 11. The pin assembly 20 includes a pin 21 and a bracket 22 connected to each other, the bracket 22 is disposed in the accommodating space 11, and when the power adapter 1 is in the open state, at least a part of the pin 21 is disposed outside the accommodating space 11. The cover 30 is rotatably connected to the adapter body 10, the cover 30 includes a first sub-cover 31 and a second sub-cover 32 that are separately connected, and when the power adapter 1 is in the closed state, the first sub-cover 31 is closer to the pins 21 than the second sub-cover 32. The flexible connecting member 40 has insulation properties, and includes a first end 41 and a second end 42 that are disposed opposite to each other, the first end 41 is disposed between the first sub-cover 31 and the second sub-cover 32, and the second end 42 is disposed between the bracket 22 and the adapter body 10.

The power adapter 1 according to the present embodiment is a conversion device that supplies power to the electronic device 2. Generally, the power adapter 1 can convert an alternating voltage into a direct voltage. For example, as shown in fig. 1, the power adapter 1 is plugged into a socket 3, receives an ac voltage output by the socket 3, and converts the received ac voltage into a dc voltage, which is used to charge an electronic device 2 that uses electricity, such as a mobile phone and a computer. It is to be understood that in other embodiments, the power adapter 1 converts the received ac voltage to a dc voltage that is directly available to the electronic components in the electronic device 2. It should be understood that the schematic diagram of the application environment of the power adapter 1 is only helpful for understanding the application of the power adapter 1, and should not be construed as limiting the power adapter 1 provided in the present application.

In addition, the electronic device 2 referred to in the present embodiment generally includes, but is not limited to, mobile terminals such as a mobile phone, a tablet Computer, a notebook Computer, a palm top Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, and a pedometer, and fixed terminals such as a Digital TV and a desktop Computer.

In addition, the power adapter 1 has a closed state and an open state, which means that the power adapter 1 is movable, i.e. closed and opened, and the closing and opening causes the pins 21 to be hidden and the pins 21 to be disposed outside the accommodating space 11. As for the specific state, the present application will be explained below.

The power adapter 1 according to the present embodiment includes an adapter body 10. Wherein the adapter body 10 can be understood as a lower cover of the power adapter 1, and structural members for protecting and installing the power adapter 1, such as various structural members, can be disposed in the receiving space 11. Since the adapter body 10 has a certain thickness, the adapter body 10 has an outer peripheral side surface 13 and an inner peripheral side surface 12 which are oppositely disposed.

The power adapter 1 of the present embodiment further includes a pin assembly 20, and the pin assembly 20 includes a pin 21 and a bracket 22 connected to each other. Wherein the pin assembly 20 is composed of a bracket 22 and a pin 21. The plug 21 is made of conductive metal, and the plug 21 is inserted into the socket 3 and used for receiving alternating voltage provided by the socket 3. The number of the pins 21 may be, but not limited to, two, and in the present embodiment, the number of the pins 21 is two. The two pins 21 are arranged oppositely and at intervals. The pins 21 may be, but are not limited to, elongated shapes. The end of the pin 21 facing away from the body of the socket 3 is curved to facilitate insertion of the pin 21 into the socket 3. When the pin 21 is inserted into the socket 3 to receive a first voltage, the circuit board is electrically connected to the pin 21 to receive the first voltage transmitted from the pin 21, and the circuit board is used to convert the first voltage into a second voltage, and the second voltage is used to charge the battery. The support 22 is a structure for disposing the pins 21, and other structural members may be disposed in the support 22, which is not described herein again.

In addition, when the power adapter 1 is in the closed state, the pins 21 are covered, including but not limited to the following cases: the pins 21 are covered by the cover 30; alternatively, the pins 21 are covered by the adapter body 10; alternatively, the pins 21 are covered by both the adapter body 10 and the cover 30. The case where the pins 21 are covered by the cover 30 is exemplified by the case where the cover 30 has receiving cavities in which the pins 21 are received when the cover 30 is closed, so as to cover the pins 21. The case where the plug pins 21 are covered by the adapter body 10 is exemplified by the case where the adapter body 10 has a housing cavity, and when the cover 30 is closed, the plug pins 21 are housed back in the housing cavity, and in this case, the plug pins 21 are covered by the adapter body 10. The plug pins 21 are covered by both the adapter body 10 and the cover 30, for example, the adapter body 10 and the cover 30 together form a receiving cavity, and when the cover 30 is closed, the plug pins 21 are received in the receiving cavity formed by both the adapter body 10 and the cover 30. The present application is illustrated with the pins 21 covered by the cover 30.

In addition, when the power adapter 1 is in the open state, at least a part of the pins 21 are disposed outside the receiving space 11. When the power adapter 1 is in the closed state, there may be any situation, but when the power adapter 1 is in the open state, at least a part of the pins 21 are disposed outside the receiving space 11, so that the pins 21 can be plugged into the sockets 3.

The power adapter 1 of the present embodiment further includes a cover 30, wherein the cover 30 is rotatably connected to the adapter body 10, so that the cover 30 can rotate relative to the adapter body 10. The number of covers 30 may be, but is not limited to, two. In the present embodiment, the number of the lid bodies 30 is two. When the two covers 30 rotate relatively and the two covers 30 abut against each other, the power adapter 1 is in a closed state (as shown in fig. 2). When the two cover bodies 30 rotate back to back and both the two cover bodies 30 abut against the adapter body 10, the power adapter 1 is in an open state (as shown in fig. 3).

The adapter body 10 has a first end 41 surface, and the cover 30 has a second end 42 surface close to the first end 41 surface when the power adapter 1 is in the closed state. When the power adapter 1 is in an open state, the first end 41 surface and the second end 42 surface together form an insertion surface of the power adapter 1, and the first end 41 surface is flush with the second end 42 surface.

Referring to fig. 6, fig. 6 is a side view of the power adapter in an open state according to an embodiment of the present application. In this embodiment, when the power adapter 1 is in the open state, the distance D between the edge of the pin 21 adjacent to the cover 30 and the edge of the cover 30 away from the pin 21 is greater than or equal to 6.5mm, or greater than or equal to 5.1mm, or greater than or equal to 7.9mm, which not only meets the requirement of safety regulations, but also realizes the structure of an ultra-thin adapter.

For the ultra-thin adapter, when the power adapter 1 is in an open state, the two covers 30 are respectively disposed on two opposite sides of the adapter body 10, as shown in fig. 3, a range of a thickness D1 of the adapter body 10 is as follows: d1 is not less than 6.3mm and not more than 14 mm; the thickness D2 of the cover 30 ranges from: d2 is not less than 4.825mm and not more than 7 mm.

In addition, the cover 30 provided in the present embodiment is not an integral structure but a split structure. For example, the cover 30 may include a first sub-cover 31 and a second sub-cover 32 that are separately connected, and when the power adapter 1 is in the closed state, the first sub-cover 31 is closer to the pins 21 than the second sub-cover 32. A structural member, such as a magnet, a flexible connecting member, etc., is disposed between the first sub-cover 31 or the second sub-cover 32 or between the first sub-cover 31 and the second sub-cover 32, so as to provide the first sub-cover 31 and the second sub-cover 32, respectively, and then the first sub-cover 31 and the second sub-cover 32 are assembled together to form the cover 30.

Referring to fig. 7, fig. 7 is a schematic cross-sectional view illustrating the pin assembly, the rotating assembly, and the first sub-cover in the rotating process according to an embodiment of the present disclosure. In the present embodiment, the power adapter 1 can rotate the cover 30 with respect to the adapter body 10 by adding the rotating member 50. For example, one end of the rotating assembly 50 is connected to the adapter body, and the other end is connected to the first cover 30. Thus, when the rotating assembly 50 rotates, the cover 30 can be driven to rotate relative to the adapter body 10.

Alternatively, the first sub-cover 31 may be provided with receiving slots 33, so that the pins 21 are received in the receiving slots 33 when the power adapter 1 is in the closed state.

It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

In the prior art, the pins 21 are connected by the bracket 22, the bracket 22 is disposed in the accommodating space 11, and the side of the bracket 22 is the adapter body 10, so the creepage distance of the power adapter 1 is short. Here, the creepage distance refers to the length of a path taken by current from the side of the pin 21 close to the adapter body 10 to the outer peripheral side 13 of the adapter body 10. As can be seen from the above, when the power adapter 1 is in the open state, the first end 41 and the second end 42 together form a plug surface, wherein the creepage distance is the length of the path taken by the current from the side of the plug 21 close to the cover 30 to the side of the cover 30 away from the adapter body 10. However, since the cover 30 is in the process of rotatably connecting the adaptor body 10, that is, when the cover is in the open state and the closed state, there is a gap between the cover 30 and the adaptor body, the creepage distance is changed, and the creepage distance is the distance from the side of the pin 21 close to the adaptor body 10 to the peripheral side 13, and the distance is too small, for example, only 1-2mm, and is far smaller than the preset safety distance, which may cause injury to the user.

Therefore, the present embodiment is provided by adding the flexible connector 40. Please refer to fig. 8-10 together, fig. 8 is a schematic perspective view of a flexible connecting element according to an embodiment of the present application. Fig. 9 is a schematic perspective view illustrating a pin assembly, a first sub-cover, and a flexible connecting member according to an embodiment of the present disclosure. Fig. 10 is an exploded view of fig. 9. The flexible connector 40 provided in this embodiment has several features, and the flexible connector 40 is used for connecting the power adapter 1. And the flexible connecting member 40 has flexibility. And after the connection, the flexible connection member 40 may be rotated when the cover body 30 is rotated. In addition, the flexible connecting member 40 has insulation, fire resistance, and high pressure resistance. Optionally, the flexible connecting element 40 is made of a fluororubber material, and the flexible connecting element 40 may be formed by compression molding.

The first end 41 of the flexible connecting member 40 is disposed between the first sub-cover 31 and the second sub-cover 32, and the second end 42 is disposed between the bracket 22 and the adapter body 10, but the flexible connecting member 40 may be disposed inside the cover 30, extend toward the receiving space 11, and be disposed between the bracket 22 and the adapter body 10. Therefore, the flexible connecting element 40 is clamped by the first sub-cover 31, the second sub-cover 32, the bracket 22 and the adapter body 10, so as to achieve the purpose of assembly.

Next, in the present embodiment, the flexible connecting members 40 are disposed between the first sub-cover 31 and the second sub-cover 32, and between the bracket 22 and the adapter body 10, when the power adapter 1 is in the closed state, since a part of the flexible connecting members 40 are disposed in the cover 30, and the rest of the flexible connecting members 40 are disposed in the accommodating space 11, the flexible connecting members 40 can be hidden inside the power adapter 1, and the user cannot observe the flexible connecting members 40, which not only improves the appearance performance of the power adapter 1, but also prevents the flexible connecting members 40 from being damaged.

Again, the second end 42 of the present embodiment is disposed between the bracket 22 and the adapter body 10, which can also be understood as separating the bracket 22 and the adapter body 10, which are disposed in close proximity in the prior art, by the flexible connecting member 40, which results in the distance between the bracket 22 and the adapter body 10 being increased by at least the thickness of the flexible connecting member 40. It should be noted that the addition of the flexible connecting member 40 does not necessarily increase the overall thickness of the power adapter 1, and can be achieved by reducing the width of the bracket 22 or reducing the width between the adapter bodies 10 while maintaining the overall thickness. Therefore, the distance between the plug pins 21 and the adapter body 10 is increased, the creepage distance is further increased, the safety performance of the power adapter 1 is improved, and the plug pins 21 are prevented from being leaked when being inserted into the sockets 3 to hurt users.

Referring to fig. 11, fig. 11 is a partial schematic view of a power adapter according to another embodiment of the present application. In this embodiment, the bracket 22 has a first portion 221 close to the pin 21 and a second portion 222 far from the pin 21, and a distance between the first portion 221 and the adapter body 10 is greater than a distance between the second portion 222 and the adapter body 10.

In this embodiment, the bracket 22 is spaced from the adapter body 10 due to the provision of the flexible connector 40. Therefore, in the present embodiment, the distance between the first portion 221 and the adapter body 10 may be larger than the distance between the second portion 222 and the adapter body 10, and it may be understood that the first portion 221 is farther from the adapter body 10 and the second portion 222 is closer to the adapter body 10.

Optionally, the distance between the first part 221 and the adapter body 10 (the length of the thick black line shown as L1 in fig. 11) is greater than the distance between the second part 222 and the adapter body 10 (the length of the thick black line shown as L2 in fig. 11) in various implementations, which is not limited in the present application. For example, this can be accomplished by changing the dimensions of the stent 22 such that the stent 22 is "small top down" even though the stent 22 has a trapezoidal cross-sectional shape. Alternatively, it is also possible to provide a protrusion (e.g., a sliding block or a positioning block) on the second portion 222, or provide a protrusion (e.g., a sliding block or a positioning block) on the adapter body 10 corresponding to the second portion 222, and so on. As shown in fig. 11, the second portion 222 of the present embodiment is shown to be provided with a protrusion, and the protrusion may be the second sliding portion 62 or the second positioning portion 72, which will be mentioned later, or may be a protrusion specially provided to increase the creepage distance.

By changing the distance, the transmission path of the current can be changed, thereby changing the creepage distance. During the transmission of the current, the current is generally transmitted toward a place with small resistance. And although the bracket 22 is spaced apart from the adapter body 10 by the bracket 22, if the spacing is too small, current can still be transmitted from the bracket 22 to the adapter body 10. Therefore, as shown in fig. 11, at this time, the current is transmitted from the side of the pin 21 close to the adapter body 10 to the side of the holder 22 close to the adapter body 10, then from the first portion 221 to the second portion 222 of the holder 22, then from the second portion 222 to the inner peripheral side 12 of the adapter through air, then from the inner peripheral side 12 to the first end 41 of the adapter, and finally from the first end 41 to the outer peripheral side 13 of the adapter body 10. The above process is understood to mean that the current is equivalent to winding around a circle and finally to the peripheral side 13, and the specific current route can refer to the course indicated by the bold black line L in fig. 5.

Like this, this embodiment alright greatly improved creepage distance under the prerequisite that does not change the whole quick-witted size of adapter, creepage distance is more than or equal to 6.5mm, makes it accord with creepage distance's requirement, improves power adapter 1's security performance.

The foregoing describes the structure and principle of the present application for satisfying the creepage distance requirement by adding the flexible connecting member 40, and next, the present application will continue to describe other problems caused by adding the flexible connecting member 40.

Referring to fig. 12-19 together, fig. 12 is a partial cross-sectional view of a power adapter according to an embodiment of the present application. FIG. 13 is a schematic partial cross-sectional view of a power adapter in accordance with another embodiment of the present application. FIG. 14 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. FIG. 15 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. FIG. 16 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. FIG. 17 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. FIG. 18 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. FIG. 19 is a schematic partial cross-sectional view of a power adapter according to yet another embodiment of the present application. Fig. 12-19 can also be understood as exploded schematic views in partial cross-section of the power adapter 1. In this embodiment, the first end 41 is slidably connected to the first sub-cover 31 or the second sub-cover 32, so that when the cover 30 rotates relative to the adapter body 10, at least a portion of the flexible connecting member 40 slides relative to the first sub-cover 31; alternatively, the first and second electrodes may be,

the second end 42 is slidably connected to the adapter body 10 or the bracket 22, and when the cover 30 rotates relative to the adapter body 10, at least a portion of the flexible connecting member 40 slides relative to the adapter body 10.

As can be seen from the above, the addition of the flexible connecting member 40 can improve the safety performance of the power adapter 1, and since the first end 41 of the flexible connecting member 40 is connected to the inside of the cover 30 and the second end 42 is connected to the inside of the accommodating space 11, the flexible connecting member 40 will also rotate together when the cover 30 rotates. However, the length of the flexible connecting element 40 at the bending position changes when the flexible connecting element 40 rotates, for example, the length of the flexible connecting element 40 increases in the process from the closed state to the open state. The length of the flexible linkage 40 decreases from the open condition to the closed condition. It will also be appreciated that the length of the flexible connector 40 in the closed position is different from the length of the flexible connector 40 in the open position due to the rotation of the cover 30. Over time or after multiple rotations, the elastic deformation becomes plastic, thereby making the flexible connector 40 susceptible to aging and damage.

Therefore, in the present embodiment, one end of the flexible connecting member 40 is fixedly connected, and the other end is slidable, so that when the cover 30 is turned over, the flexible connecting member 40 is driven to rotate, but because the other end of the flexible connecting member 40 is slidable, the length change caused by the outer bending of the flexible connecting member 40 is compensated by sliding, and the requirements of different lengths of the flexible material in the opening state and the closing state are met. The problem of flexible connection piece 40 easy ageing and damage is solved, the flexible life of connecting piece has been improved.

In addition, the present embodiment provides various realizable embodiments, the first end 41 is slidably connected to the first sub-cover 31 or the second sub-cover 32, so that when the cover 30 rotates relative to the adapter body 10, at least a portion of the flexible connecting element 40 slides relative to the first sub-cover 31. Alternatively, the second end 42 is slidably connected to the adaptor body 10 or the bracket 22, and when the cover 30 rotates relative to the adaptor body 10, at least a portion of the flexible connecting member 40 slides relative to the adaptor body 10.

Referring to fig. 20 to 21, fig. 20 is a partial schematic view illustrating a power adapter in a closed state according to an embodiment of the present application. Fig. 21 is a partial schematic view illustrating a power adapter in an open state according to an embodiment of the present application. In this embodiment, the flexible connecting member 40 includes a bending portion 43 and a connecting portion 44 connected to each other, and the first sliding portion 61 is disposed on the connecting portion 44; when the power adapter 1 is in the closed state, the sliding block is close to the bent part 43 in the sliding hole; when the power adapter 1 is in the open state, the slider is far away from the bent portion 43 in the sliding hole.

From the above, in the present application, the first sliding portion 61 and the second sliding portion 62 are matched to slide to compensate for the length change of the flexible connector 40 caused by bending. And the application also provides a specific implementation mode, namely, the sliding block is matched with the sliding hole to realize sliding. Therefore, in the present embodiment, regardless of the specific arrangement position and relationship between the slider and the sliding hole, when the power adapter 1 is in the closed state, the slider is close to the bent portion 43 in the sliding hole; when the power adapter 1 is in the open state, the slider is away from the bent portion 43 in the sliding hole, so that the sliding relationship is realized.

The above description describes the end of the flexible connector 40 that is used for sliding, and the following description describes the end of the flexible connector 40 that is used for fixing.

Referring to fig. 12 to fig. 19 again, in this embodiment, the power adapter 1 further includes an adhesive member 70, and when one end of the adhesive member 70 is adhered to the first end 41, the other end of the adhesive member 70 is adhered to the first sub-cover 31 or the second sub-cover 32; alternatively, the first and second electrodes may be,

when one end of the adhesive member 70 is adhered to the second end 42, the other end of the adhesive member 70 is adhered to the adapter body 10 or the bracket 22.

Alternatively, as shown in fig. 14-15, when one end of the adhesive member 70 is adhered to the second end 42, the other end of the adhesive member 70 is adhered to the stent 22.

In addition, as can be seen from the above, one end of the flexible connecting member 40 is used for fixed connection, and the other end is used for sliding, so the adhesive member 70 and the first sliding portion 61 and the second sliding portion 62 are not provided at the same end, i.e. the adhesive member 70 and the first sliding portion 61 and the second sliding portion 62 are provided at opposite ends.

Referring to fig. 12 to fig. 19 again, in this embodiment, when one end of the adhesive member 70 is adhered to the first end 41, the first end 41 is provided with a first positioning portion 71, the first sub-cover 31 or the second sub-cover 32 is provided with a second positioning portion 72, and the first positioning portion 71 and the second positioning portion 72 are matched with each other to position the flexible connecting member 40; alternatively, the first and second electrodes may be,

when one end of the adhesive member 70 is adhered to the second end 42, the second end 42 is provided with a first positioning portion 71, and the adapter body 10 or the bracket 22 is provided with a second positioning portion 72.

Alternatively, as shown in fig. 14 to 15, when one end of the adhesive member 70 is adhered to the second end 42, the second end 42 is provided with a first positioning portion 71, and the adapter body 10 is provided with a second positioning portion 72. Alternatively, as shown in fig. 12 to 13, when one end of the adhesive member 70 is adhered to the second end 42, the second end 42 is provided with a first positioning portion 71, and the bracket 22 is provided with a second positioning portion 72.

Referring to fig. 12 to 19 again, in the present embodiment, the first positioning portion 71 includes a positioning block or a positioning hole, and when the first positioning portion 71 includes a positioning block, the second positioning portion 72 includes a positioning hole; alternatively, when the positioning portion includes a positioning hole, the second positioning portion 72 includes a positioning block.

Further, the first positioning portion 71 may specifically include a positioning block or a positioning hole. And when the first positioning portion 71 includes a positioning block, the second positioning portion 72 includes a positioning hole corresponding to the positioning block. Alternatively, when the positioning portion includes a positioning hole, the second positioning portion 72 includes a positioning block corresponding to the positioning hole. In addition, fig. 12 to 19 only illustrate some schematic diagrams of possible embodiments, and other configurations of the power adapter 1 not illustrated in the drawings should also fall within the scope of the present application.

In addition, the above mentioned slide holes and positioning holes do not necessarily mean that the slide holes and positioning holes must penetrate through two opposite surfaces to form a through hole. Or only penetrates through one surface, so that a structure similar to a groove is formed, as long as the sliding space and the positioning space are formed, and at least part of the sliding block and the positioning block can be accommodated.

Referring to fig. 22, fig. 22 is a partial cross-sectional view of a power adapter according to another embodiment of the present application. In the present embodiment, when the first sliding portion 61 includes a slider, the second sliding portion 62 includes a sliding hole, or when the first positioning portion 71 includes a positioning block, and the second positioning portion 72 includes at least one positioning hole, the flexible connecting member 40 includes a bent portion 43, a connecting portion 44, and a reinforcing portion 45, the bent portion 43 is connected to the connecting portion 44, the reinforcing portion 45 is provided on one side of the connecting portion 44, and at least one of the first sliding portion 61 and the first positioning portion 71 is provided on the other side of the connecting portion 44.

At least one of the slide block and the positioning block can be classified into two schemes, one is that at least one of the slide block and the positioning block is arranged on the flexible connecting piece 40, and the other is that at least one of the slide block and the positioning block is not arranged on the flexible connecting piece 40. When at least one of a slider and a positioning block is provided on the flexible connecting element 40, that is, when the first sliding portion 61 includes a slider and the second sliding portion 62 includes a sliding hole, or when the first positioning portion 71 includes a positioning block and the second positioning portion 72 includes at least one of positioning holes. At this time, the flexible connecting member 40 can be reinforced, so that the difficulty of fitting the slider or the positioning block into the slide hole and the positioning hole is reduced, and the slider or the positioning block can be prevented from being separated from the slide hole or the positioning hole. In order to achieve the above object, the present application provides two specific implementations.

In the first implementation manner, i.e. the present embodiment, the flexible connecting member 40 may include a bending portion 43, a connecting portion 44, and a reinforcing portion 45. Wherein the bent portion 43 is connected to the connecting portion 44. The bent portion 43 is a portion for bending the flexible connection member 40 along with it when the cover 30 is bent, and the connection portion 44 is not used for bending, and maintains a horizontal shape regardless of the state. But the connection 44 is used to mount other components. For example, the reinforcing portion 45 is provided on one side of the connecting portion 44, and at least one of the first sliding portion 61 and the first positioning portion 71 is provided on the other side of the connecting portion 44. Because the connecting portion 44 does not need to be bent, the reinforcing portion 45 can be arranged on the connecting portion 44, so that the overall rigidity of the connecting portion 44 is improved, the difficulty of installing the slider or the positioning block into the sliding hole and the positioning hole is reduced, and the slider or the positioning block is prevented from being separated from the sliding hole or the positioning hole. Optionally, the reinforcement 45 is a rigid reinforcement 45. In the present embodiment, the first sliding portion 61 includes a slider, and the second sliding portion 62 includes a slide hole. The first positioning portion 71 includes a positioning block, and the second positioning portion 72 includes a positioning hole for illustration.

Referring to fig. 23, fig. 23 is a partial cross-sectional view of a power adapter according to another embodiment of the present application. In this embodiment, when the first sliding portion 61 includes a slider, the second sliding portion 62 includes a sliding hole, or when the first positioning portion 71 includes a positioning block and the second positioning portion 72 includes at least one positioning hole, the flexible connecting member 40 includes a bending portion 43 and a reinforcing portion 45 connected to each other, and at least one of the first sliding portion 61 and the first positioning portion 71 is disposed on the reinforcing portion 45.

In the second implementation manner, i.e. the present embodiment, the flexible connecting member 40 includes a bending portion 43 and a reinforcing portion 45 connected to each other. It can also be understood that the reinforcing portion 45 is directly used instead of the connecting portion 44 to increase the rigidity of the portion, and at least one of the first sliding portion 61 and the first positioning portion 71 is directly provided on the reinforcing portion 45, so that the cost and the thickness of the flexible connecting member 40 can be reduced.

Referring to fig. 24, fig. 24 is a schematic view illustrating a slider disposed on a first sub-cover according to another embodiment of the present application. In this embodiment, the slider has a free surface 64, and a distance between the free surface 64 and the flexible connecting member 40, the first sub-cover 31, the second sub-cover 32, the bracket 22, or the adaptor body 10 is smaller than a thickness of the flexible connecting member 40.

In this embodiment, when the slider is provided, the slider has a connection surface 63 and a free surface 64 which are opposite to each other, and the connection surface 63 is used to connect the slider to various components. While the free surface 64 is a surface disposed opposite to the connection surface 63, referring to fig. 5, fig. 20 to fig. 21 again, in the present embodiment, the distance between the free surface 64 and the flexible connection member 40, the first sub-cover 31, the second sub-cover 32, the bracket 22, or the adapter body 10 may be made smaller than the thickness of the flexible connection member 40, so that even if there is a gap between the free surface 64 and the corresponding structural member, the flexible connection member 40 may be prevented from falling from the gap, and thus the flexible connection member 40 may be assembled well.

Referring to fig. 24 again, in the present embodiment, the flexible connecting member 40 includes a bending portion 43 and a connecting portion 44 connected to each other, and an avoiding groove 46 is formed at a side of the bending portion 43 close to the first sub-cover 31 and the bracket 22.

In the present embodiment, the flexible connecting member 40 may include a bending portion 43 and a connecting portion 44, and the bending portion 43 and the connecting portion 44 are already described in the above embodiments of the present application, and are not described herein again. And an avoiding groove 46 is formed at one side of the bending part 43 close to the first sub-cover 31 and the bracket 22. Thus, the protruding portions of the first sub-cover 31 and the bracket 22 can be avoided, and the thickness of the bent portion 43 can be reduced, so that the bending performance of the bent portion 43 can be improved.

The foregoing detailed description has provided for the embodiments of the present application, and the principles and embodiments of the present application have been presented herein for purposes of illustration and description only and to facilitate understanding of the methods and their core concepts; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
