具体实施方式Detailed ways

为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳的实施例。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。In order to facilitate the understanding of the application, the application will be described in a more comprehensive manner with reference to the relevant drawings. The preferred embodiments of the application are shown in the accompanying drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and comprehensive.

如图1和图4所示，在一实施例中，提供一种电源适配器10，包括本体、保护盖20和铰链机构40。本体包括壳体30和插脚60，插脚60连接于壳体30。可以理解的是，“连接”包括直接连接和间接连接，直接连接为插脚60直接连接于壳体30，间接连接为插脚60连接于壳体30内的元件，从而能够固定于壳体30或能够相对于壳体30移动。壳体30具有第一表面33，保护盖20连接于第一表面33，本申请中以插脚60凸出于第一表面33为例进行详细说明。As shown in FIGS. 1 and 4, in one embodiment, a power adapter 10 is provided, which includes a body, a protective cover 20 and a hinge mechanism 40. The body includes a housing 30 and pins 60, and the pins 60 are connected to the housing 30. It can be understood that "connection" includes direct connection and indirect connection. A direct connection means that the pin 60 is directly connected to the housing 30, and an indirect connection means that the pin 60 is connected to an element in the housing 30 so as to be fixed to the housing 30 or capable of Move with respect to the housing 30. The housing 30 has a first surface 33, and the protective cover 20 is connected to the first surface 33. In this application, the pins 60 protrude from the first surface 33 as an example for detailed description.

铰链机构40连接于壳体30和保护盖20之间，使得保护盖20能够相对于壳体30转动，从而使电源适配器10具有闭合状态和打开状态。如图1所示，在闭合状态时，保护盖20盖设于壳体30，插脚60的至少部分结构被收容于保护盖20或壳体30内，使得保护盖20或壳体30能够保护插脚60。如图4所示，保护盖20具有与壳体30连接的第二表面140，在打开状态时，保护盖20的第二表面140与壳体30的第一表面33平齐或存在设定范围内的高度差，并形成工作配合面90。电源适配器10与外接电源电连接时，工作配合面90为电源适配器10的贴合或靠近外接电源的面。The hinge mechanism 40 is connected between the housing 30 and the protective cover 20, so that the protective cover 20 can rotate relative to the housing 30, so that the power adapter 10 has a closed state and an open state. As shown in FIG. 1, in the closed state, the protective cover 20 is provided on the housing 30, and at least part of the structure of the pins 60 is housed in the protective cover 20 or the housing 30, so that the protective cover 20 or the housing 30 can protect the pins 60. As shown in FIG. 4, the protective cover 20 has a second surface 140 connected to the housing 30. In the open state, the second surface 140 of the protective cover 20 is flush with the first surface 33 of the housing 30 or has a set range. The height difference within and forms a working mating surface 90. When the power adapter 10 is electrically connected to an external power source, the working mating surface 90 is the surface of the power adapter 10 that is attached to or close to the external power source.

可以理解的是，在本申请实施例中描述的所有“平齐”也可为“大致平齐”，平齐可以是完全在一个平面内，也可以存在一定范围内的高度差，比如保护盖20的第二表面140与第一表面33之间的高度差不大于2mm或5mm或不大于10mm或其它尺寸，比如高度差不大于1mm，此种情况也在本申请的保护范围内。It is understandable that all the “levels” described in the embodiments of this application can also be “approximately level”. The leveling can be completely in a plane, or there can be a height difference within a certain range, such as a protective cover. The height difference between the second surface 140 and the first surface 33 of 20 is not more than 2mm or 5mm or not more than 10mm or other dimensions, for example, the height difference is not more than 1mm. This situation is also within the protection scope of the present application.

在一实施例中，插脚60与工作配合面90的边缘之间的距离不小于预设值，比如5.1mm或6.5mm或7.9mm，使得电源适配器10能够满足安规要求。可以理解的是，电源适配器10具有长度方向、宽度方向和厚度方向，在电源适配器10的厚度方向和宽度方向上，插脚60到工作配合面90的边缘的距离均不小于预设值。In an embodiment, the distance between the pin 60 and the edge of the working mating surface 90 is not less than a preset value, such as 5.1 mm or 6.5 mm or 7.9 mm, so that the power adapter 10 can meet the safety requirements. It can be understood that the power adapter 10 has a length direction, a width direction and a thickness direction. In the thickness direction and the width direction of the power adapter 10, the distance from the pin 60 to the edge of the working mating surface 90 is not less than a preset value.

本申请的电源适配器10，保护盖20通过铰链机构40能够相对于壳体30转动而位于闭合状态和打开状态。在闭合状态下，插脚60被保护盖20或壳体30保护，避免暴露，从而不会刺伤靠近电源适配器10的物体，且能够保护插脚60，便于携带。在打开状态下，第二表面140与第一表面33形成工作配合面90，而满足电源适配器10的使用要求(如，安规要求)，从而壳体30本身的厚度可设置得较小(如，远小于上述的预设值)，使得电源适配器10的整体体积相比与相关技术比如插脚通过转动而折叠收纳于壳体内的电源适配器的体积可大幅缩小。In the power adapter 10 of the present application, the protective cover 20 can be rotated relative to the housing 30 through a hinge mechanism 40 to be in a closed state and an open state. In the closed state, the pins 60 are protected by the protective cover 20 or the housing 30 to avoid exposure, so as not to puncture objects close to the power adapter 10, and can protect the pins 60 for easy portability. In the open state, the second surface 140 and the first surface 33 form a working mating surface 90, which meets the use requirements of the power adapter 10 (such as safety requirements), so that the thickness of the housing 30 itself can be set smaller (such as , Much smaller than the above-mentioned preset value), so that the overall volume of the power adapter 10 can be greatly reduced compared with the related technology, such as the volume of the power adapter that is folded and housed in the housing by the rotation of the pins.

如图1和图4所示，在一实施例中，保护盖20包括第一保护盖100和第二保护盖200，二者均固定于壳体30的第一表面33的边缘的相背设置的两侧，与插脚60位于壳体30的同一端部。在闭合状态下，第一保护盖100和第二保护盖200相互贴合。在打开状态下，第一保护盖100和第二保护盖200分别贴合于壳体30的相背的两侧。As shown in FIGS. 1 and 4, in an embodiment, the protective cover 20 includes a first protective cover 100 and a second protective cover 200, both of which are fixed to the edge of the first surface 33 of the housing 30 and are arranged opposite to each other. Both sides of the pin 60 are located at the same end of the housing 30. In the closed state, the first protective cover 100 and the second protective cover 200 are attached to each other. In the open state, the first protective cover 100 and the second protective cover 200 are attached to opposite sides of the housing 30, respectively.

如图1至图4所示，在一实施例中，电源适配器10的长度方向沿Y方向设置，宽度方向沿X方向设置，厚度方向沿Z方向设置。插脚60沿电源适配器10的长度方向即Y方向延伸，即插脚60的长度方向为Y方向。壳体30包括第三表面31、第四表面32、第一表面33、第十表面34、第十一表面35和第十二表面36，第三表面31和第四表面32相背设置，第十一表面35和第十二表面36相背设置，第一表面33和第十表面34相背设置。第三表面31和第四表面32定义电源适配器10的厚度方向即Z方向，第十一表面35和第十二表面36定义电源适配器10的宽度方向即X方向，第一表面33和第十表面34定义壳体30的长度方向，电源适配器10的长度方向即Y方向与壳体30的长度方向相同。插脚60沿电源适配器10的长度方向延伸至壳体30之外。在另一实施例中，插脚60也可以沿电源适配器10的宽度方向延伸，可根据电源适配器10的实际需求进行相应设计。第一保护盖100连接于第一表面33和第三表面31的交界处，第二保护盖200连接于第一表面33和第四表面32的交界处。As shown in FIGS. 1 to 4, in one embodiment, the length direction of the power adapter 10 is set along the Y direction, the width direction is set along the X direction, and the thickness direction is set along the Z direction. The pin 60 extends along the length direction of the power adapter 10, that is, the Y direction, that is, the length direction of the pin 60 is the Y direction. The housing 30 includes a third surface 31, a fourth surface 32, a first surface 33, a tenth surface 34, an eleventh surface 35, and a twelfth surface 36. The third surface 31 and the fourth surface 32 are arranged opposite to each other. The eleventh surface 35 and the twelfth surface 36 are arranged opposite to each other, and the first surface 33 and the tenth surface 34 are arranged opposite to each other. The third surface 31 and the fourth surface 32 define the thickness direction of the power adapter 10, namely the Z direction, the eleventh surface 35 and the twelfth surface 36 define the width direction of the power adapter 10, namely the X direction, the first surface 33 and the tenth surface 34 defines the length direction of the casing 30, and the length direction of the power adapter 10, that is, the Y direction, is the same as the length direction of the casing 30. The pins 60 extend to the outside of the housing 30 along the length of the power adapter 10. In another embodiment, the pins 60 can also extend along the width direction of the power adapter 10, and can be designed according to the actual requirements of the power adapter 10. The first protective cover 100 is connected to the junction of the first surface 33 and the third surface 31, and the second protective cover 200 is connected to the junction of the first surface 33 and the fourth surface 32.

在一实施例中，保护盖20的厚度与第一表面33在电源适配器10的厚度方向上的尺寸一致。“一致”可以理解为“相等”或“大致相等”。保护盖20包括第一保护盖100和第二保护盖200时，保护盖20的厚度为第一保护盖100和第二保护盖200在电源适配器10的厚度方向即Z方向上的尺寸之和。从而在闭合状态下，第一保护盖100的背离第二保护盖200的一侧的表面与第三表面31能够平齐或大致平齐，第二保护盖200的背离第一保护盖100的一侧的表面与第四表面32能够平齐或大致平齐，使得电源适配器10在闭合状态下尺寸较薄，便于携带。In an embodiment, the thickness of the protective cover 20 is consistent with the size of the first surface 33 in the thickness direction of the power adapter 10. "Identical" can be understood as "equal" or "approximately equal." When the protective cover 20 includes the first protective cover 100 and the second protective cover 200, the thickness of the protective cover 20 is the sum of the dimensions of the first protective cover 100 and the second protective cover 200 in the thickness direction of the power adapter 10, that is, in the Z direction. Therefore, in the closed state, the surface of the first protective cover 100 on the side facing away from the second protective cover 200 can be flush or substantially flush with the third surface 31, and the second protective cover 200 is facing away from the first protective cover 100. The side surface and the fourth surface 32 can be flush or substantially flush, so that the power adapter 10 has a thinner size in the closed state and is convenient to carry.

在另一实施例中，保护盖20也可以仅包括第一保护盖100，则保护盖20的厚度为第一保护盖100在电源适配器10的厚度方向即Z方向上的尺寸。第一保护盖100在Z方向上的尺寸即第一保护盖100的厚度，与第一表面33在Z方向上的尺寸一致。在闭合状态下，第一保护盖100在Z方向上的两侧的表面分别与第三表面31、第四表面32平齐或大致平齐，使得电源适配器10尺寸较薄，便于携带。在打开状态下，第一保护盖100贴合或大致贴合于壳体30的第三表面31或第四表面32，使得第二表面140与第一表面33平齐或大致平齐，形成工作配合面90，插脚60与工作配合面90的边缘之间的距离不小于预设值，而满足电源适配器10的使用要求(如，安规要求)。本申请以保护盖20包括第一保护盖100和第二保护盖200为例进行详细说明。可以理解的是，保护盖20仅包括第一保护盖100，第一保护盖100的厚度与壳体30的厚度一致的情况也在本申请的保护范围之内。In another embodiment, the protective cover 20 may also include only the first protective cover 100, and the thickness of the protective cover 20 is the size of the first protective cover 100 in the thickness direction of the power adapter 10, that is, in the Z direction. The size of the first protective cover 100 in the Z direction, that is, the thickness of the first protective cover 100, is consistent with the size of the first surface 33 in the Z direction. In the closed state, the surfaces on both sides of the first protective cover 100 in the Z direction are flush or substantially flush with the third surface 31 and the fourth surface 32, respectively, so that the power adapter 10 has a thinner size and is convenient to carry. In the open state, the first protective cover 100 is attached or substantially attached to the third surface 31 or the fourth surface 32 of the housing 30, so that the second surface 140 is flush or substantially flush with the first surface 33, forming a working The distance between the mating surface 90, the pin 60 and the edge of the working mating surface 90 is not less than a preset value, and meets the use requirements of the power adapter 10 (eg, safety requirements). In this application, the protective cover 20 includes the first protective cover 100 and the second protective cover 200 as an example for detailed description. It is understandable that the protective cover 20 only includes the first protective cover 100, and the case where the thickness of the first protective cover 100 is consistent with the thickness of the housing 30 is also within the protection scope of the present application.

在另一实施例中，在插脚60的长度方向即Y方向上，第一卡槽121延伸至第二表面140和第十三表面130，第二卡槽221延伸至第九表面240和第十六表面230；即第一保护盖100、第二保护盖200均与插脚60的凸出于壳体30的长度相等，则在电源适配器10闭合状态下，插脚60分别与第十三表面130、第十六表面230平齐，使得电源适配器10的长度尺寸较小，较为轻薄，便于携带。In another embodiment, in the Y direction that is the length direction of the pin 60, the first slot 121 extends to the second surface 140 and the thirteenth surface 130, and the second slot 221 extends to the ninth surface 240 and the tenth surface. Six surfaces 230; that is, the first protective cover 100 and the second protective cover 200 are equal to the length of the pin 60 protruding from the housing 30. When the power adapter 10 is closed, the pin 60 and the thirteenth surface 130, The sixteenth surface 230 is flush, so that the length of the power adapter 10 is small, light and thin, and easy to carry.

可以理解的是，第一卡槽121延伸至第二表面140，第二卡槽221延伸至第九表面240，但工作配合面90定义为忽略第一卡槽121和第二卡槽221时，第二表面140、第一表面33和第九表面240在打开状态下形成的面。当保护盖20的数量为1时，工作配合面90定义为忽略第一卡槽121时，第二表面140和第一表面33在打开状态下形成的面。It can be understood that when the first slot 121 extends to the second surface 140, and the second slot 221 extends to the ninth surface 240, but the working mating surface 90 is defined as ignoring the first slot 121 and the second slot 221, The second surface 140, the first surface 33, and the ninth surface 240 are formed in an open state. When the number of the protective cover 20 is 1, the working mating surface 90 is defined as the surface formed by the second surface 140 and the first surface 33 in the open state when the first slot 121 is omitted.

在一实施例中，插脚60的数量为2个，则第一卡槽121和第二卡槽221的数量均为2个。在另一实施例中，插脚60的数量为1个、3个或多个，则第一卡槽121、第二卡槽221的数量与插脚60的数量相对应。插脚60的形状可以为圆柱形，也可以为扁平状，在此不做具体限定。本申请中，以插脚60为长条形的扁平状结构为例进行详细说明。在打开状态下，插脚60的长度方向沿电源适配器10的长度方向即Y方向设置，插脚60的宽度方向沿电源适配器10的厚度方向即Z方向设置，插脚60的厚度方向沿电源适配器10的宽度方向即X方向设置。In an embodiment, the number of pins 60 is two, and the number of the first slot 121 and the number of the second slot 221 are both two. In another embodiment, the number of the pins 60 is one, three or more, and the number of the first slot 121 and the second slot 221 corresponds to the number of the pins 60. The shape of the pin 60 may be cylindrical or flat, which is not specifically limited here. In the present application, a detailed description is given by taking the elongated flat structure of the pin 60 as an example. In the open state, the length direction of the pin 60 is set along the length direction of the power adapter 10, that is, the Y direction, the width direction of the pin 60 is set along the thickness direction of the power adapter 10, that is, the Z direction, and the thickness direction of the pin 60 is along the width of the power adapter 10. The direction is the X direction setting.

在另一实施例中，第一保护盖100为中空开口的盒装结构，第二保护盖200为中空开口的盒装结构。在闭合状态下，第一保护盖100和第二保护盖200形成封闭的内部空间，插脚60容纳于第一保护盖100和第二保护盖200形成的内部空间内，且插脚60的数量不被限制。In another embodiment, the first protective cover 100 is a boxed structure with a hollow opening, and the second protective cover 200 is a boxed structure with a hollow opening. In the closed state, the first protective cover 100 and the second protective cover 200 form a closed internal space, the pins 60 are accommodated in the internal space formed by the first protective cover 100 and the second protective cover 200, and the number of the pins 60 is not limited. limit.

图2和图7所示，在一实施例中，电源适配器10的打开状态与闭合状态相比，第一保护盖100和第二保护盖200以电源适配器10的宽度方向为轴分别旋转了180°左右，即电源适配器10在闭合状态时，将第一保护盖100和第二保护盖200相对于壳体30旋转180°，使得第五表面110与第三表面31贴合固定，第七表面210和第四表面32贴合固定，电源适配器10即处于打开状态。As shown in FIGS. 2 and 7, in an embodiment, the open state of the power adapter 10 is compared with the closed state, and the first protective cover 100 and the second protective cover 200 are rotated by 180 with the width direction of the power adapter 10 as the axis. ° around, that is, when the power adapter 10 is in the closed state, rotate the first protective cover 100 and the second protective cover 200 relative to the housing 30 by 180°, so that the fifth surface 110 and the third surface 31 are attached and fixed, and the seventh surface 210 and the fourth surface 32 are attached and fixed, and the power adapter 10 is in an open state.

在一实施例中，在打开状态下，插脚60的长度方向垂直于第一表面33，“垂直”可以理解为“大致垂直”，从而插脚60能够***外接电源的孔内，使得外接电源能够通过电源适配器10为电子设备充电。在闭合状态和打开状态之间，插脚60相对于第一表面33倾斜，比如插脚60沿电源适配器10的厚度方向即Z方向倾斜，或者沿宽度方向即X方向倾斜，即插脚60的长度方向与第一表面33的夹角为锐角。使得在该状态下，插脚60无法***外接电源的孔中，使得电源适配器10在闭合状态和打开状态之间无法与外接电源电性连接。可以理解的是，在闭合状态和打开状态之间，用户需采用手指夹持壳体30的第三表面31和第四表面32，则插脚60和用户手指之间的距离可能小于预设值而不满足安规要求，从而使得用户具有触电的危险。通过设置插脚60在在闭合状态和打开状态之间时相对于第一表面33倾斜，使得插脚60无法***外接电源的孔内，从而避免用户具有触电危险。In one embodiment, in the open state, the length of the pin 60 is perpendicular to the first surface 33, and "vertical" can be understood as "substantially vertical", so that the pin 60 can be inserted into the hole of the external power source, so that the external power source can pass through The power adapter 10 charges the electronic device. Between the closed state and the open state, the pin 60 is inclined with respect to the first surface 33. For example, the pin 60 is inclined along the thickness direction of the power adapter 10, that is, the Z direction, or along the width direction, that is, the X direction. The included angle of the first surface 33 is an acute angle. In this state, the pin 60 cannot be inserted into the hole of the external power source, so that the power adapter 10 cannot be electrically connected to the external power source between the closed state and the open state. It is understandable that between the closed state and the open state, the user needs to clamp the third surface 31 and the fourth surface 32 of the housing 30 with fingers, and the distance between the pin 60 and the user's finger may be less than the preset value. Does not meet the safety requirements, which makes the user have the risk of electric shock. By setting the pin 60 to be inclined relative to the first surface 33 between the closed state and the open state, the pin 60 cannot be inserted into the hole of the external power source, thereby avoiding the risk of electric shock for the user.

在另一实施例中，在打开状态下，插脚60的宽度方向垂直于电源适配器10的长度方向和宽度方向所在的平面，即插脚60的宽度方向垂直于XY平面，即插脚60的厚度方向与Z方向相同。从而插脚60能够***外接电源的孔内，使得外接电源能够通过电源适配器10为电子设备充电。在闭合状态和打开状态之间，插脚60的宽度方向与电源适配器10的长度方向和宽度方向所在的平面的夹角为锐角，即插脚60的宽度方向与XY平面的夹角为锐角。可以理解为，在闭合状态和打开状态之间，插脚60由打开状态绕Y轴轴向旋转了设定角度。使得2个插脚60大致平行且错位，从而无法***外接电源的孔中，使得电源适配器10在闭合状态和打开状态之间无法与外接电源电性连接，避免用户具有触电危险。In another embodiment, in the open state, the width direction of the pin 60 is perpendicular to the plane where the length and width directions of the power adapter 10 are located, that is, the width direction of the pin 60 is perpendicular to the XY plane, that is, the thickness direction of the pin 60 and The Z direction is the same. Therefore, the pin 60 can be inserted into the hole of the external power source, so that the external power source can charge the electronic device through the power adapter 10. Between the closed state and the open state, the angle between the width direction of the pin 60 and the plane where the length and width directions of the power adapter 10 are located is an acute angle, that is, the angle between the width direction of the pin 60 and the XY plane is an acute angle. It can be understood that, between the closed state and the open state, the pin 60 is axially rotated by a set angle around the Y axis from the open state. The two pins 60 are approximately parallel and misaligned so that they cannot be inserted into the holes of the external power supply, so that the power adapter 10 cannot be electrically connected to the external power supply between the closed state and the open state, thereby avoiding the risk of electric shock for the user.

再一实施例中，插脚60能够相对于壳体30伸缩移动而凸出于第一表面33或收容于壳体30内部。在打开状态下，插脚60完全伸出壳体30，从而能够***外接电源的孔内，使得外接电源能够通过电源适配器10为电子设备充电。在闭合状态和打开状态之间，插脚60的部分结构收容于壳体30内，即插脚60不完全凸出于第一表面33，使得插脚60***外接电源的孔内时，插脚60无法接触外接电源的孔内的PIN点等电性连接件，使得电源适配器10无法与外接电源电性连接。可以理解的是，在闭合状态和打开状态之间，用户需采用手指夹持壳体30的第三表面31和第四表面32，则插脚60和用户手指之间的距离可能小于预设值而不满足安规要求，从而使得用户具有触电的危险。通过设置插脚60在在闭合状态和打开状态之间时不完全凸出于第一表面33，即使插脚60凸出的部分***外接电源的孔内，也无法接触外接电源内的PIN点，从而避免用户具有触电危险。In still another embodiment, the pin 60 can telescopically move relative to the housing 30 to protrude from the first surface 33 or be housed in the housing 30. In the open state, the pin 60 completely extends out of the housing 30 so that it can be inserted into the hole of the external power source, so that the external power source can charge the electronic device through the power adapter 10. Between the closed state and the open state, part of the structure of the pin 60 is housed in the housing 30, that is, the pin 60 does not completely protrude from the first surface 33, so that when the pin 60 is inserted into the hole of the external power supply, the pin 60 cannot touch the external Electrical connectors such as PIN points in the holes of the power supply prevent the power adapter 10 from being electrically connected to the external power supply. It is understandable that between the closed state and the open state, the user needs to clamp the third surface 31 and the fourth surface 32 of the housing 30 with fingers, and the distance between the pin 60 and the user's finger may be less than the preset value. Does not meet the safety requirements, which makes the user have the risk of electric shock. By setting the pin 60 to not completely protrude from the first surface 33 between the closed state and the open state, even if the protruding part of the pin 60 is inserted into the hole of the external power supply, it cannot touch the PIN point in the external power supply, thereby avoiding The user is at risk of electric shock.

如图4和图7所示，在一实施例中，插脚60的数量为2个，2个插脚60在电源适配器10的宽度方向即X方向上排列设置，2个插脚60与第三表面31之间的距离均为L1，且2个插脚60与第四表面32之间的距离均为L2。电源适配器10在打开状态下，2个插脚60与第六表面120之间的距离均为L3，L3等于第一保护盖100的厚度与L1之和；2个插脚60与第八表面220之间的距离均为L4，L4等于第二保护盖200的厚度与L2之和。在打开状态下，插脚60与工作配合面90的边缘的距离为L3、L4中的最小值。As shown in FIGS. 4 and 7, in one embodiment, the number of pins 60 is two, and the two pins 60 are arranged in a row in the width direction of the power adapter 10, that is, in the X direction. The two pins 60 and the third surface 31 The distance between them is L1, and the distance between the two pins 60 and the fourth surface 32 is L2. When the power adapter 10 is in the open state, the distance between the two pins 60 and the sixth surface 120 is L3, and L3 is equal to the sum of the thickness of the first protective cover 100 and L1; between the two pins 60 and the eighth surface 220 The distance between is L4, and L4 is equal to the sum of the thickness of the second protective cover 200 and L2. In the open state, the distance between the pin 60 and the edge of the working mating surface 90 is the minimum value of L3 and L4.

安全规范要求即安规要求中规定，电源适配器10在打开状态下，插脚60到工作配合面90的边缘的距离不小于预设值。在一些实施例中，预设值可以为6.5mm，也可以为其它数据，比如5.1mm或7.9mm，具体根据电源适配器10的使用情况确定。可以理解的是，在打开状态下，在电源适配器10的厚度方向即Z方向，插脚60到工作配合面90的边缘的距离不小于预设值；且在电源适配器10的宽度方向即X方向，插脚60到工作配合面90的边缘的距离不小于预设值。在一实施例中，L1等于L2，即2个插脚60在第一表面33上对称设置，L3等于L4，则插脚60距离工作配合面90的边缘的最小值为L3或L4，L3或L4不小于预设值。L1小于预设值，比如为2.65mm，L3不小于预设值，比如为8.4mm。The safety regulations require that the distance from the pin 60 to the edge of the working mating surface 90 is not less than a preset value when the power adapter 10 is in the open state. In some embodiments, the preset value may be 6.5 mm, or may be other data, such as 5.1 mm or 7.9 mm, which is specifically determined according to the usage of the power adapter 10. It can be understood that, in the open state, in the thickness direction of the power adapter 10, that is, the Z direction, the distance from the pin 60 to the edge of the working mating surface 90 is not less than a preset value; and in the width direction of the power adapter 10, that is, the X direction, The distance from the pin 60 to the edge of the working mating surface 90 is not less than a preset value. In one embodiment, L1 is equal to L2, that is, the two pins 60 are symmetrically arranged on the first surface 33, and L3 is equal to L4, then the minimum distance between the pins 60 and the edge of the working mating surface 90 is L3 or L4, and L3 or L4 is not Less than the preset value. L1 is less than a preset value, such as 2.65 mm, and L3 is not less than a preset value, such as 8.4 mm.

在另一实施例中，L1不等于L2，即2个插脚60在第一表面33上为非对称设置，比如2个插脚60靠近第三表面31，则L1小于L2，则L3小于L4，则插脚60距离工作配合面90的边缘的最小值为L3，L3不小于预设值；再比如，2个插脚60靠近第四表面32，则L1大于L2，则L3大于L4，则插脚60距离工作配合面90的边缘的最小值为L4，L4不小于预设值。在该实施例中，L1和L2均小于预设值，L3和L4均不小于预设值。In another embodiment, L1 is not equal to L2, that is, the two pins 60 are arranged asymmetrically on the first surface 33.

如图9至图11所示，在一实施例中，基座43的两端分别设有第一凸柱431和第二凸柱432，第一凸柱431和第二凸柱432可以位于基座43的同一侧，也可以位于基座43的相背设置的两侧，且第一凸柱431和第二凸柱432相互平行。第一组活动件的第一活动件41固定于保护盖20，且第一活动件41与基座43通过第一凸柱431滑动或转动连接，第一组活动件的第二活动件42固定于壳体30，第二活动件42与基座43通过第二凸柱432滑动或转动连接。如图9和图12所示，第一活动件41和第二活动件42相向转动时，保护盖20能够从闭合状态切换至打开状态。第一活动件41和第二活动件42相背转动时，保护盖20能够从打开状态切换至闭合状态。As shown in FIGS. 9 to 11, in one embodiment, a first protrusion 431 and a second protrusion 432 are respectively provided at both ends of the base 43, and the first protrusion 431 and the second protrusion 432 may be located on the base. The same side of the base 43 may also be located on opposite sides of the base 43, and the first protrusion 431 and the second protrusion 432 are parallel to each other. The first movable part 41 of the first group of movable parts is fixed to the protective cover 20, and the first movable part 41 and the base 43 are slidably or rotatably connected by the first protrusion 431, and the second movable part 42 of the first group of movable parts is fixed In the housing 30, the second movable member 42 and the base 43 are slidably or rotatably connected by a second protrusion 432. As shown in FIGS. 9 and 12, when the first movable member 41 and the second movable member 42 rotate toward each other, the protective cover 20 can be switched from the closed state to the open state. When the first movable part 41 and the second movable part 42 rotate opposite to each other, the protective cover 20 can be switched from the open state to the closed state.

如图11和图13所示，在一实施例中，第一活动件41开设有第一导向槽411，第二活动件42开设有第二导向槽421。第一凸柱431与第一滑槽411滑动配合，使得第一活动件41能够相对于基座43滑动以及转动，从而能够呈现如图9和图12所示的状态。第二凸柱432与第二导向槽421滑动配合，使得第二活动件42能够相对于基座43互动以及转动，从而能够呈现如图9和图12所示的状态。As shown in FIGS. 11 and 13, in one embodiment, the first movable member 41 is provided with a first guide groove 411, and the second movable member 42 is provided with a second guide groove 421. The first protrusion 431 and the first sliding groove 411 are slidably engaged, so that the first movable member 41 can slide and rotate relative to the base 43, thereby being able to assume the state shown in FIGS. 9 and 12. The second protruding column 432 is slidingly fitted with the second guide groove 421, so that the second movable member 42 can interact and rotate relative to the base 43, thereby being able to assume the state shown in FIGS. 9 and 12.

如图14所示，在一实施例中，第一定位块433和第二定位块434的横截面均为椭圆形，第一凸柱431和第二凸柱432的横截面均为圆形。第一定位块433的中心点与第一凸柱431分别在第一导向槽411的两端时的中心点之间的连线的夹角β1等于90°，可满足第一活动件41在第一状态下相对于基座43旋转90°后切换至第二状态。第二定位块434的中心点与第二凸柱432分别在第二导向槽421的两端时的中心点之间的连线的夹角β2等于90°，可满足第二活动件42在第一状态下相对于基座43旋转90°后切换至第二状态。As shown in FIG. 14, in one embodiment, the cross-sections of the first positioning block 433 and the second positioning block 434 are both oval, and the cross-sections of the first protrusion 431 and the second protrusion 432 are both circular. The included angle β1 of the line between the center point of the first positioning block 433 and the center point of the first protrusion 431 at the two ends of the first guide groove 411 is equal to 90°, which can satisfy that the first movable part 41 is in the first In one state, it is rotated 90° with respect to the base 43 and then switched to the second state. The angle β2 of the line between the center point of the second positioning block 434 and the center point of the second protrusion 432 at the two ends of the second guide groove 421 is equal to 90°, which can satisfy that the second movable member 42 is in the first In one state, it is rotated 90° with respect to the base 43 and then switched to the second state.

如图13和图14所示，第一导向槽411和第二导向槽421均为弧形槽。第一导向槽411的弧度向第一定位块433凸出，第二导向槽421的弧度向第二定位块434凸出。在另一实施例中，第一导向槽411和第二导向槽421也可以为直形槽，同样可以使得第一活动件41相对于基座43旋转90°以在第一状态和第二状态之间切换，且使得第二活动件42相对于基座43旋转90°以在第一状态和第二状态之间切换。As shown in FIGS. 13 and 14, the first guide groove 411 and the second guide groove 421 are both arc-shaped grooves. The arc of the first guide groove 411 protrudes toward the first positioning block 433, and the arc of the second guide groove 421 protrudes toward the second positioning block 434. In another embodiment, the first guide groove 411 and the second guide groove 421 can also be straight grooves, which can also make the first movable member 41 rotate 90° relative to the base 43 to be in the first state and the second state. The second movable member 42 is rotated by 90° relative to the base 43 to switch between the first state and the second state.

如图13和图14所示，在一实施例中，第一导向槽411和第二导向槽421为圆弧形槽，即在F1和F2所在的平面上，第一导向槽411和第二导向槽421的沿圆弧形轨迹延伸，且第一导向槽411和第二导向槽421所对的圆心角小于90°，使得第一活动件41和第二活动件42能够相对于基座43进行90°的旋转，从而能够在第一状态和第二状态之间切换。可以理解的是，第一活动件41相对于基座43转动时，第一定位块433相对于第一定位槽412即存在转动的动作又存在滑动的动作，第一定位块433相对于第一定位槽412的滑动使得第一导向槽411所对的圆心角小于90°时，第一活动件41能够相对于基座43转动90°。同理，第二导向槽421所对的圆心角小于90°，第二凸柱432沿第二导向槽421的滑动，以及第二定位块434相对于第二定位槽422的转动和滑动，使得第二活动件42能够相对于基座43旋转90°以在第一状态和第二状态之间切换。As shown in Figures 13 and 14, in an embodiment, the first guide groove 411 and the second guide groove 421 are arc-shaped grooves, that is, on the plane where F1 and F2 are located, the first guide groove 411 and the second guide groove 411 The guide groove 421 extends along the arc-shaped track, and the central angle of the first guide groove 411 and the second guide groove 421 is less than 90°, so that the first movable part 41 and the second movable part 42 can be relative to the base 43. Perform a 90° rotation to switch between the first state and the second state. It can be understood that when the first movable member 41 rotates relative to the base 43, the first positioning block 433 rotates and slides relative to the first positioning groove 412, and the first positioning block 433 is relative to the first positioning groove 412. When the sliding of the positioning groove 412 makes the center angle of the first guide groove 411 less than 90°, the first movable member 41 can rotate 90° with respect to the base 43. In the same way, the central angle of the second guide groove 421 is less than 90°, the sliding of the second protrusion 432 along the second guide groove 421, and the rotation and sliding of the second positioning block 434 relative to the second positioning groove 422 make The second movable member 42 can rotate 90° with respect to the base 43 to switch between the first state and the second state.

在第一状态和第二状态之间，第一导向槽411和第二导向槽421的弧形相向凸出，形成如图14所示的结构。在第一状态和第二状态之间，第一导向槽411和第二导向槽421所对的圆心分别位于第一导向槽411、第二导向槽421的相互背离的一侧。即第一导向槽411所对的圆心位于第一导向槽411的背离第二导向槽421的一侧，第二导向槽421所对的圆心位于第二导向槽421的背离第一导向槽411的一侧。可以理解的是，第一导向槽411和第二导向槽421也可以相背凸出，且第一导向槽411和第二导向槽421对应的圆心角可以均为90°，第一导向槽411和第二导向槽421一起能够形成半圆形结构。Between the first state and the second state, the arcs of the first guide groove 411 and the second guide groove 421 protrude toward each other, forming a structure as shown in FIG. 14. Between the first state and the second state, the centers of the circles of the first guide groove 411 and the second guide groove 421 are respectively located on the sides of the first guide groove 411 and the second guide groove 421 that face away from each other. That is, the center of the first guide groove 411 is located on the side of the first guide groove 411 away from the second guide groove 421, and the center of the second guide groove 421 is located on the side of the second guide groove 421 away from the first guide groove 411. One side. It can be understood that the first guide groove 411 and the second guide groove 421 may also protrude opposite to each other, and the center angles corresponding to the first guide groove 411 and the second guide groove 421 may both be 90°, and the first guide groove 411 Together with the second guide groove 421, a semicircular structure can be formed.

如图14和图15b所示，基座43包括位于第二方向F2两端且相背设置的第一侧438和第二侧439。在第一状态时，第一活动件41和第二活动件42均凸出于第一侧438；在第二状态时，第一活动件41和第二活动件42一端均凸出于第二侧439，另一端与第一侧438平齐。第一凸柱431和第二凸柱432靠近第一侧438。第一定位块433与第一侧438之间的距离大于第一凸柱431与第一侧438之间的距离。第二定位块434与第一侧438之间的距离大于第二凸柱432与第一侧438之间的距离。第一定位块433和第二定位块434大致位于第一侧438和第二侧439的中间位置。这种设置使得铰链机构40在第二状态时，第一活动件41、第二活动件42能够与第一侧438平齐，从而使得电源适配器10位于打开状态时，铰链机构40暴露的面不存在凸凹不平的情况。As shown in FIGS. 14 and 15b, the base 43 includes a first side 438 and a second side 439 that are located at opposite ends of the second direction F2. In the first state, both the first movable part 41 and the second movable part 42 protrude from the first side 438; in the second state, one end of the first movable part 41 and the second movable part 42 protrudes from the second side. Side 439, the other end is flush with the first side 438. The first protrusion 431 and the second protrusion 432 are close to the first side 438. The distance between the first positioning block 433 and the first side 438 is greater than the distance between the first protrusion 431 and the first side 438. The distance between the second positioning block 434 and the first side 438 is greater than the distance between the second protrusion 432 and the first side 438. The first positioning block 433 and the second positioning block 434 are approximately located in the middle of the first side 438 and the second side 439. This arrangement enables the first movable piece 41 and the second movable piece 42 to be flush with the first side 438 when the hinge mechanism 40 is in the second state, so that when the power adapter 10 is in the open state, the exposed surface of the hinge mechanism 40 is not There are bumps and bumps.

第一活动件41相对于基座43转动时，第一活动件41相对于第一定位块433转动的同时也存在滑动的情况。即第一定位槽412绕第一定位块433转动时，第一定位块433也沿第一定位槽412滑动，使得第一活动件41相对于基座43转动和滑动，从而使得第一活动件41能够在第一状态和第二状态之间切换。同样的，第二活动件42相对于基座43转动时，第二定位块434相对于第二定位槽422转动和滑动。When the first movable part 41 rotates relative to the base 43, the first movable part 41 rotates relative to the first positioning block 433 while sliding. That is, when the first positioning groove 412 rotates around the first positioning block 433, the first positioning block 433 also slides along the first positioning groove 412, so that the first movable part 41 rotates and slides relative to the base 43, so that the first movable part 41 can switch between the first state and the second state. Similarly, when the second movable member 42 rotates relative to the base 43, the second positioning block 434 rotates and slides relative to the second positioning slot 422.

如图13和图14所示，在一实施例中，第一定位槽412倾斜开设于第一活动件41的朝向基座43的一侧，且第一定位槽412的一端与第一导向槽411连通，另一端延伸至第一活动件41的边缘，使得第一活动件41能够方便地安装于基座43和从基座43拆离。且第一定位槽412给第一定位块433预留了足够的滑动空间。第二定位槽422倾斜开设于第二活动件42的朝向基座43的一侧，且第二定位槽422的一端与第二导向槽421连通，另一端延伸至第二活动件42的边缘，使得第二活动件42能够方便地安装于基座43和从基座43拆离。且第二定位槽422给第二定位块434预留了足够的滑动空间。As shown in FIGS. 13 and 14, in one embodiment, the first positioning groove 412 is formed obliquely on the side of the first movable member 41 facing the base 43, and one end of the first positioning groove 412 is connected to the first guide groove. 411 is connected, and the other end extends to the edge of the first movable part 41, so that the first movable part 41 can be easily installed on and detached from the base 43. Moreover, the first positioning slot 412 reserves sufficient sliding space for the first positioning block 433. The second positioning groove 422 is formed obliquely on the side of the second movable part 42 facing the base 43, and one end of the second positioning groove 422 is communicated with the second guide groove 421, and the other end extends to the edge of the second movable part 42. Therefore, the second movable part 42 can be easily installed on and detached from the base 43. Moreover, the second positioning slot 422 reserves sufficient sliding space for the second positioning block 434.

可以理解的是，第一导向槽411和第二导向槽421的弧形相向凸出，形成如图14所示的结构。该设置与“第一定位块433、第二定位块434能够分别在第一定位槽412、第二定位槽422内滑动”结合在一起，使得铰链机构40由第一状态向第二状态切换时，第一活动件41首先具有一个远离第二活动件42的动作，使得第一活动件41和第二活动件42之间的间距增大。铰链机构40装配在电源适配器10后，电源适配器10由闭合状态切换至打开状态时，保护盖20首先具有一个远离壳体30的动作，使得保护盖20和壳体30之间的间距增大，避免二者之间转动时产生干涉，从而可以避免在保护盖20和壳体30的相互靠近的一端设置倒角，即第五表面110和第二表面140的交汇处为直角，第三表面31和第一表面33的交汇处为直角。从而电源适配器10位于闭合状态时，如图1所示，保护盖20和壳体30之间的间距较小，使得电源适配器10具有完整的外观结构，外观整体性较好。It can be understood that the arcs of the first guide groove 411 and the second guide groove 421 protrude toward each other, forming a structure as shown in FIG. 14. This arrangement is combined with "the first positioning block 433 and the second positioning block 434 can respectively slide in the first positioning groove 412 and the second positioning groove 422", so that when the hinge mechanism 40 is switched from the first state to the second state , The first movable part 41 first has an action to move away from the second movable part 42 so that the distance between the first movable part 41 and the second movable part 42 is increased. After the hinge mechanism 40 is assembled on the power adapter 10, when the power adapter 10 is switched from the closed state to the open state, the protective cover 20 first moves away from the housing 30, which increases the distance between the protective cover 20 and the housing 30. Avoid interference between the two when rotating, so as to avoid setting chamfers at the end of the protective cover 20 and the housing 30 close to each other, that is, the intersection of the fifth surface 110 and the second surface 140 is a right angle, and the third surface 31 The intersection with the first surface 33 is a right angle. Therefore, when the power adapter 10 is in the closed state, as shown in FIG. 1, the distance between the protective cover 20 and the housing 30 is relatively small, so that the power adapter 10 has a complete appearance structure and good appearance integrity.

在一实施例中，第一定位块433和第二定位块434的横截面均为椭圆形结构。如图13和图14所示，在第一状态时，第一定位块433的横截面的长轴垂直于第一定位槽412的槽壁，第一定位块433与第一定位槽412的槽壁之间的最小距离为S1；第二定位块434的横截面的长轴垂直于第二定位槽422的槽壁，第二定位块434与第二定位槽422的槽壁之间的最小距离同样为S1。如图15a和图15b所示，在第二状态时，第一定位块433的横截面的短轴垂直于第一定位槽412的槽壁，第一定位块433与第一定位槽412的槽壁之间的最小距离为S2；第二定位块434的横截面的短轴垂直于第二定位槽422的槽壁，第二定位块434与第二定位槽422的槽壁之间的最小距离同样为S2。则S2大于S1。可以理解的是，在第一状态和第二状态之间，第一定位块433和第一定位槽412的槽壁之间的最小距离大于S1并小于S2；第二定位块434和第二定位槽422的槽壁之间的最小距离大于S1并小于S2。铰链机构40由第一状态向第二状态切换的过程中，第一定位块433和第一定位槽412的槽壁之间的最小距离逐渐增加，第二定位块434和第二定位槽422的槽壁之间的最小距离同步逐渐增加。In an embodiment, the cross-sections of the first positioning block 433 and the second positioning block 434 are both oval-shaped structures. As shown in Figures 13 and 14, in the first state, the long axis of the cross section of the first positioning block 433 is perpendicular to the groove wall of the first positioning groove 412. The minimum distance between the walls is S1; the long axis of the cross section of the second positioning block 434 is perpendicular to the wall of the second positioning groove 422, and the minimum distance between the second positioning block 434 and the wall of the second positioning groove 422 The same is S1. As shown in Figures 15a and 15b, in the second state, the short axis of the cross section of the first positioning block 433 is perpendicular to the groove wall of the first positioning groove 412, and the first positioning block 433 and the first positioning groove 412 The minimum distance between the walls is S2; the short axis of the cross section of the second positioning block 434 is perpendicular to the wall of the second positioning groove 422, and the minimum distance between the second positioning block 434 and the wall of the second positioning groove 422 The same is S2. Then S2 is greater than S1. It can be understood that between the first state and the second state, the minimum distance between the first positioning block 433 and the wall of the first positioning groove 412 is greater than S1 and less than S2; the second positioning block 434 and the second positioning The minimum distance between the groove walls of the groove 422 is greater than S1 and less than S2. When the hinge mechanism 40 is switched from the first state to the second state, the minimum distance between the first positioning block 433 and the groove wall of the first positioning groove 412 gradually increases, and the distance between the second positioning block 434 and the second positioning groove 422 is gradually increased. The minimum distance between the groove walls gradually increases simultaneously.

铰链机构40的第一状态对应电源适配器10的闭合状态，第一定位块433和第一定位槽412的槽壁之间的最小距离S1较小甚至趋近于0，使得二者之间的装配较为紧凑，增加电源适配器10在闭合状态的稳定性。铰链机构40的第二状态对应电源适配器10的打开状态，第一定位块433和第一定位槽412的槽壁之间的最小距离S2大于S1，使得二者之间具有活动间隙，方便用户闭合电源适配器10，且方便第一定位块433在第一定位槽412内滑动。The first state of the hinge mechanism 40 corresponds to the closed state of the power adapter 10. The minimum distance S1 between the first positioning block 433 and the wall of the first positioning groove 412 is small or even close to 0, so that the assembly between the two It is more compact and increases the stability of the power adapter 10 in the closed state. The second state of the hinge mechanism 40 corresponds to the open state of the power adapter 10. The minimum distance S2 between the first positioning block 433 and the wall of the first positioning groove 412 is greater than S1, so that there is a movable gap between them, which is convenient for the user to close The power adapter 10 is convenient for the first positioning block 433 to slide in the first positioning slot 412.

在另一实施例中，第一定位块433和第二定位块434的横截面也可以为非椭圆形结构，但需存在长轴和短轴，以满足S1小于S2。第一定位块433和第二定位块434的横截面可以为跑道型结构，不规则的圆形结构或其它结构，在此不做限定。In another embodiment, the cross-sections of the first positioning block 433 and the second positioning block 434 may also have a non-elliptical structure, but a long axis and a short axis are required to satisfy that S1 is smaller than S2. The cross-sections of the first positioning block 433 and the second positioning block 434 may be a racetrack-shaped structure, an irregular circular structure or other structures, which are not limited herein.

The two second movable parts 42 are respectively located on both sides of the third direction F3 of the base 43, and the two second movable parts 42 are arranged diagonally. That is, on both sides of the base 43 in the third direction F3, the first movable part 41 is covered and fixed to the second movable part 42, and the two rotate and slide synchronously. The two first movable parts 41 and the two second movable parts 42 are assembled to form an accommodating cavity 437, and at least part of the structure of the base 43 is located in the accommodating cavity 437.

位于基座43的第三方向F3一侧的1个第一活动件41和1个第二活动件42组成第一组活动件，位于基座43的第三方向F3另一侧的1个第一活动件41和1个第二活动件42组成第二组活动件。第一组活动件包括的第一活动件41和第二活动件42能够相对于基座43相向或相背转动以在第一状态和第二状态之间切换。第二组活动件包括的第一活动件41和第二活动件42能够相对于基座43相向或相背转动以在第一状态和第二状态之间切换。第一组活动件内的第一活动件41和第二组活动件内的第二活动件42固定在一起且同步转动，第二组活动件内的第二活动件42和第二组活动件内的第一活动件41固定在一起且同步转动。A first movable part 41 and a second movable part 42 located on one side of the third direction F3 of the base 43 constitute the first group of movable parts, and a second movable part located on the other side of the third direction F3 of the base 43 A movable piece 41 and a second movable piece 42 constitute the second group of movable pieces. The first movable member 41 and the second movable member 42 included in the first group of movable members can be rotated toward or away from the base 43 to switch between the first state and the second state. The first movable part 41 and the second movable part 42 included in the second group of movable parts can be rotated toward or away from the base 43 to switch between the first state and the second state. The first movable piece 41 in the first group of movable pieces and the second movable piece 42 in the second group of movable pieces are fixed together and rotate synchronously, and the second movable piece 42 in the second group of movable pieces and the second group of movable pieces The first movable parts 41 inside are fixed together and rotate synchronously.

在另一实施例中，第一活动件41和第二活动件42的结构相同，均为L形结构。可以理解为，基座43的第三方向F3的两侧分别设置2个第一活动件41，位于基座43的第三方向F3的两侧的第一活动件41两两固定，形成容纳腔437，基座43的至少部分结构位于容纳腔437内。In another embodiment, the first movable part 41 and the second movable part 42 have the same structure, and both have an L-shaped structure.

The first state of the hinge mechanism 40 corresponds to the closed state of the power adapter 10, and the second state corresponds to the open state of the power adapter 10. 16(b) is a process diagram of the first protective cover 100 being switched from the closed state to the open state, and FIG. 16(a) is a process diagram of the hinge mechanism 40 corresponding to the switching from the first state to the second state. In the closed state, as the first protective cover 100 rotates, the first movable part 41 and the base 43 rotate relative to the second movable part 42, so that the first protrusion 431 and the second protrusion 432 are respectively guided by the first One end of the groove 411 and the second guide groove 421 slides toward the other end, and the first positioning block 433 and the second positioning block 434 rotate and slide in the first positioning groove 412 and the second positioning groove 422, respectively.

In this state, the hinge mechanism 40 assumes the state shown in FIGS. 25 to 27. Compared with the state of the hinge mechanism 40 shown in FIGS. 20 to 23, the base 43 is further inclined with respect to the second movable member 42. The second protrusion 432 is closer to the other end of the second guide groove 421, and at the same time, due to the further rotation of the second positioning groove 422 relative to the second positioning block 434, the second positioning block 434 and the groove wall of the second positioning groove 422 are The distance between them is further increased. Similarly, the first protrusion 431 is closer to the other end of the first guide groove 411, and at the same time, due to the further rotation of the first positioning groove 412 relative to the first positioning block 433, the first positioning block 433 and the first positioning groove 412 are further rotated.

In this state, the hinge mechanism 40 assumes the state shown in FIGS. 15a and 15b. Compared with the state shown in FIGS. 25 to 27, the base 43 rotates further until the second protrusion 432 is located at the other end of the second guide groove 421, and the short axis of the cross section of the second positioning block 434 is perpendicular to the second For the groove wall of the positioning groove 422, the distance between the second positioning block 434 and the groove wall of the second positioning groove 422 reaches the maximum, which is S2.

The first protrusion 431 and the second protrusion 432 slide from one end of the first guide groove 411 and the second guide groove 421 to the other end, respectively. The first positioning block 433 and the second positioning block 434 are respectively converted from the long axis perpendicular to the groove walls of the first positioning groove 412 and the second positioning groove 422 to the short axis perpendicular to the first positioning groove 412 and the second positioning groove 422.

如图5和图41所示，在一实施例中，第一保护盖100内设有第一磁性体125，第二保护盖200内设有第二磁性体225。第一磁性体125与第二磁性体225之间存在相互吸引的磁力，使得第一保护盖100和第二保护盖200之间存在相互吸引的磁力。在第一状态下，第一磁性体125和第二磁性体225的靠近的两极极性相反，比如，第一磁性体125的靠近第二磁性体225的一侧为N极，则第二磁性体225的靠近第一磁性体125的一侧为S极。第一保护盖100和第二保护盖200之间通过第一磁性体125和第二磁性体225之间相互吸引的磁力磁吸并贴合固定。在第二状态下，第一磁性体125和第二磁性体225的靠近的两极极性相反，第一保护盖100和第二保护盖200之间通过第一磁性体125和第二磁性体225之间相互吸引的磁力磁吸并分别贴合固定于壳体30的相背的两侧。在一实施例中，第一磁性体125和第二磁性体225均为磁铁。As shown in FIGS. 5 and 41, in an embodiment, the first protective cover 100 is provided with a first magnetic body 125, and the second protective cover 200 is provided with a second magnetic body 225. There is an attractive magnetic force between the first magnetic body 125 and the second magnetic body 225, so that there is an attractive magnetic force between the first protective cover 100 and the second protective cover 200. In the first state, the adjacent poles of the first magnetic body 125 and the second magnetic body 225 have opposite polarities. The side of the body 225 close to the first magnetic body 125 is an S pole. The first protective cover 100 and the second protective cover 200 are magnetically attracted by the magnetic force between the first magnetic body 125 and the second magnetic body 225 to be attached to each other and fixed. In the second state, the polarities of the approaching poles of the first magnetic body 125 and the second magnetic body 225 are opposite, and the first magnetic body 125 and the second magnetic body 225 pass between the first protective cover 100 and the second protective cover 200. The mutually attracted magnetic force is magnetically attracted and fixed to the opposite sides of the casing 30 respectively. In one embodiment, the first magnetic body 125 and the second magnetic body 225 are both magnets.

在另一实施例中，第一磁性体125可以位于第一保护盖100的第五表面110，第二磁性体225可以位于第二保护盖200的第七表面210，同样能够使得第一保护盖100和第二保护盖200之间存在相互吸引的磁力。In another embodiment, the first magnetic body 125 may be located on the fifth surface 110 of the first protective cover 100, and the second magnetic body 225 may be located on the seventh surface 210 of the second protective cover 200, which can also make the first protective cover There is a magnetic force between 100 and the second protective cover 200 that attracts each other.

如图1和图2所示，电源适配器10在第一状态，第一保护盖100和第二保护盖200之间通过第一磁性体125和第二磁性体225磁吸固定，且第一磁性体125和第二磁性体225的磁力穿过第六表面120和第八表面220。用户放置于口袋或行李箱中时，第一保护盖100和第二保护盖200隐藏插脚60，避免插脚60擦伤周围物体，且第一保护盖100和第二保护盖200不容易打开，使得电源适配器10在存放或运输过程中能够可靠的隐藏插脚60。As shown in Figures 1 and 2, the power adapter 10 is in the first state, the first protective cover 100 and the second protective cover 200 are magnetically fixed by the first magnetic body 125 and the second magnetic body 225, and the first magnetic body The magnetic force of the body 125 and the second magnetic body 225 penetrates the sixth surface 120 and the eighth surface 220. When the user places it in a pocket or suitcase, the first protective cover 100 and the second protective cover 200 hide the pins 60 to prevent the pins 60 from scratching surrounding objects, and the first protective cover 100 and the second protective cover 200 are not easy to open, so The power adapter 10 can reliably hide the pins 60 during storage or transportation.

如图2、图6和图7所示，在一实施例中，第一磁性体125和第二磁性体225之间的相互吸引的磁力包括第一磁力F1和第二磁力F2。第一磁力F1为第一磁性体125朝向第六表面120的一侧和第二磁性体225朝向第八表面220的一侧因极性相反而产生的磁吸力，第一磁力F1穿过第六表面120和第八表面220，使得第一保护盖100和第二保护盖200具有转动至闭合状态的趋势；第二磁力F2为第一磁性体125朝向第五表面110的一侧和第二磁性体225朝向第七表面210的一侧因极性相反而产生的磁吸力，第二磁力F2穿过第五表面110、第七表面210和壳体30，使得第一保护盖100和第二保护盖200具有转动至打开状态的趋势。As shown in FIGS. 2, 6 and 7, in one embodiment, the magnetic force attracting each other between the first magnetic body 125 and the second magnetic body 225 includes a first magnetic force F1 and a second magnetic force F2. The first magnetic force F1 is the magnetic attraction force generated by the opposite polarity between the side of the first magnetic body 125 facing the sixth surface 120 and the side of the second magnetic body 225 facing the eighth surface 220. The first magnetic force F1 passes through the sixth surface. The surface 120 and the eighth surface 220 make the first protective cover 100 and the second protective cover 200 have a tendency to rotate to the closed state; the second magnetic force F2 is the side of the first magnetic body 125 facing the fifth surface 110 and the second magnetic The side of the body 225 facing the seventh surface 210 generates a magnetic attraction force due to the opposite polarity. The second magnetic force F2 penetrates the fifth surface 110, the seventh surface 210 and the housing 30, so that the first protective cover 100 and the second protective cover 100 The cover 200 has a tendency to rotate to an open state.

如图2和图41所示，电源适配器10在闭合状态下，第一保护盖100和第二保护盖200之间依靠第一磁性体125和第二磁性体225之间的第一磁力F1而被吸紧不张开。需要打开第一保护盖100和第二保护盖200时，用户需给第一保护盖100或第二保护盖200施力以克服第一磁性体125和第二磁性体225之间的第一磁力F1，使得第一保护盖100或第二保护盖200能够相对于壳体30旋转。如图6和图42所示，存在临界角度α，临界角度α为第一保护盖100或第二保护盖200与壳体30之间的角度，即第五表面110与第三表面31所在的平面之间的夹角，或为第七表面210与第四表面32所在的平面之间的夹角。第一保护盖100和第二保护盖200其中之一位于闭合状态或打开状态，第一保护盖100和第二保护盖200其中之另一与壳体30之间的角度为临界角度α时，第一磁力F1和第二磁力F2处于平衡状态，即第一磁力F1和第二磁力F2相互作用使得第一保护盖100和第二保护盖200处于平衡状态。第一保护盖100和第二保护盖200其中之一位于打开状态，第一保护盖100和第二保护盖200其中之另一与壳体30之间的角度大于临界角度α时，第一磁力F1大于第二磁力F2，第一保护盖100和第二保护盖200能够自动回复至闭合状态。第一保护盖100和第二保护盖200其中之一位于闭合状态，第一保护盖100和第二保护盖200其中之另一与壳体30之间的角度小于临界角度α时，第一磁力F1小于第二磁力F2，第一保护盖100和第二保护盖200能够自动回复至打开状态。As shown in Figures 2 and 41, when the power adapter 10 is in the closed state, the first protective cover 100 and the second protective cover 200 rely on the first magnetic force F1 between the first magnetic body 125 and the second magnetic body 225. Is sucked tightly and does not open. When it is necessary to open the first protective cover 100 and the second protective cover 200, the user needs to apply force to the first protective cover 100 or the second protective cover 200 to overcome the first magnetic force between the first magnetic body 125 and the second magnetic body 225 F1, so that the first protective cover 100 or the second protective cover 200 can rotate relative to the housing 30. As shown in Figures 6 and 42, there is a critical angle α, which is the angle between the first protective cover 100 or the second protective cover 200 and the housing 30, that is, where the fifth surface 110 and the third surface 31 are located. The angle between the planes may be the angle between the plane on which the seventh surface 210 and the fourth surface 32 are located. When one of the first protective cover 100 and the second protective cover 200 is in a closed state or an open state, and the angle between the other of the first protective cover 100 and the second protective cover 200 and the housing 30 is the critical angle α, The first magnetic force F1 and the second magnetic force F2 are in a balanced state, that is, the first magnetic force F1 and the second magnetic force F2 interact so that the first protective cover 100 and the second protective cover 200 are in a balanced state. When one of the first protective cover 100 and the second protective cover 200 is in an open state, and the angle between the other of the first protective cover 100 and the second protective cover 200 and the housing 30 is greater than the critical angle α, the first magnetic force F1 is greater than the second magnetic force F2, and the first protective cover 100 and the second protective cover 200 can automatically return to the closed state. When one of the first protective cover 100 and the second protective cover 200 is in the closed state, and the angle between the other of the first protective cover 100 and the second protective cover 200 and the housing 30 is less than the critical angle α, the first magnetic force F1 is smaller than the second magnetic force F2, and the first protective cover 100 and the second protective cover 200 can automatically return to the open state.

如图41至图43所示，假定用户对第一保护盖100施力，第一保护盖100旋转，第二保护盖200保持静止。此时，第一磁力F1大于第二磁力F2，使得第一保护盖100和第二保护盖200具有回复至闭合状态的趋势。从闭合状态开始旋转第一保护盖100，且未到达第一保护盖100与壳体30之间的夹角为临界夹角α的状态时，第一磁力F1逐渐减弱，第二磁力F2逐渐增强，且第一磁力F1大于第二磁力F2，使得第一保护盖100和第二保护盖200具有回复至闭合状态的趋势。当第一保护盖100旋转至与壳体30之间的夹角为临界角度α时，第一磁力F1和第二磁力F2处于平衡状态，使得第一保护盖100和第二保护盖200能够处于平衡状态，理想情况下，第一保护盖100和第二保护盖200能够在该状态下保持静止。随着用户继续施力，第一磁力F1继续减小，第二磁力F2继续增强，但第一磁力F1始终小于第二磁力F2，则用户可停止对第一保护盖100施力，第二磁力F2促使第一保护盖100和第二保护盖200相对于壳体30自动旋转，直至第一保护盖100、第二保护盖200均与壳体30贴合。电源适配器10在打开状态下，用户使用电源适配器10对电子元件供电时，第一保护盖100和第二保护盖200固定贴合于壳体30且不会晃动或旋转，方便使用。可以理解的是，需打开电源适配器10时，用户也可以选择对第二保护盖200进行施力，同样能够打开电源适配器10，且工作原理与用户对第一保护盖100进行施力的方式相同。As shown in FIGS. 41 to 43, it is assumed that the user applies a force to the first protective cover 100, the first protective cover 100 rotates, and the second protective cover 200 remains stationary. At this time, the first magnetic force F1 is greater than the second magnetic force F2, so that the first protective cover 100 and the second protective cover 200 have a tendency to return to the closed state. When the first protective cover 100 is rotated from the closed state, and the angle between the first protective cover 100 and the housing 30 is not reached to the critical angle α, the first magnetic force F1 gradually weakens, and the second magnetic force F2 gradually increases , And the first magnetic force F1 is greater than the second magnetic force F2, so that the first protective cover 100 and the second protective cover 200 have a tendency to return to the closed state. When the first protective cover 100 rotates to the critical angle α between the first protective cover 100 and the housing 30, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, so that the first protective cover 100 and the second protective cover 200 can be in a balanced state. In a balanced state, ideally, the first protective cover 100 and the second protective cover 200 can remain stationary in this state. As the user continues to apply force, the first magnetic force F1 continues to decrease, and the second magnetic force F2 continues to increase, but the first magnetic force F1 is always smaller than the second magnetic force F2, the user can stop applying force to the first protective cover 100, and the second magnetic force F2 causes the first protection cover 100 and the second protection cover 200 to automatically rotate relative to the housing 30 until the first protection cover 100 and the second protection cover 200 are both attached to the housing 30. When the power adapter 10 is in the open state, when the user uses the power adapter 10 to supply power to electronic components, the first protective cover 100 and the second protective cover 200 are fixedly attached to the housing 30 without shaking or rotating, which is convenient for use. It is understandable that when the power adapter 10 needs to be opened, the user can also choose to apply force to the second protective cover 200, and the power adapter 10 can also be opened, and the working principle is the same as that of the user applying force to the first protective cover 100 .

在一实施例中，电源适配器10在打开状态下，第一保护盖100和第二保护盖200依靠第一磁性体125和第二磁性体225之间的第二磁力F2被吸紧不张开。需要闭合电源适配器10时，用户需给第一保护盖100或第二保护盖200施力以克服第一磁性体125和第二磁性体225之间的第二磁力F2，使得第一保护盖100或第二保护盖200能够相对于壳体30旋转。假定用户对第一保护盖100施力，第一保护盖100离开壳体30并旋转，第二保护盖200保持与壳体30贴合的状态。随着第一保护盖100的旋转，第二磁力F2减弱，第一磁力F1逐渐增加，但第二磁力F2始终大于第一磁力F1。当第一保护盖100旋转至与壳体30之间的角度为临界角度α时，第一磁力F1和第二磁力F2处于平衡状态，即第一保护盖100和第二保护盖200在第一磁力F1和第二磁力F2的共同作用下处于平衡状态，理想情况下，第一保护盖100和第二保护盖200能够处于静止状态。随着用户继续对第一保护盖100施力，则打破第一磁力F1和第二磁力F2之间的平衡状态，使得第一磁力F1大于第二磁力F2，用户可停止对第一保护盖100施力。第一磁力F1能够促使第一保护盖100和第二保护盖200相对于壳体30自动旋转，直至第一保护盖100和第二保护盖200贴合固定，使得电源适配器10处于闭合状态。电源适配器10在闭合状态下，在存储或运输或日常放置、移动过程中，第一保护盖100和第二保护盖200之间紧密固定，具有隐藏插脚60的可靠性，且厚度较薄，方便携带。可以理解的是，需闭合电源适配器10时，用户也可以选择对第二保护盖200进行施力，同样能够闭合电源适配器10，且工作原理与用户对第一保护盖100进行施力的方式相同。In one embodiment, when the power adapter 10 is in the open state, the first protective cover 100 and the second protective cover 200 rely on the second magnetic force F2 between the first magnetic body 125 and the second magnetic body 225 to be sucked and not opened. . When the power adapter 10 needs to be closed, the user needs to apply force to the first protective cover 100 or the second protective cover 200 to overcome the second magnetic force F2 between the first magnetic body 125 and the second magnetic body 225, so that the first protective cover 100 Or the second protective cover 200 can rotate relative to the housing 30. Assuming that the user applies force to the first protective cover 100, the first protective cover 100 leaves the housing 30 and rotates, and the second protective cover 200 remains in a state of being attached to the housing 30. As the first protective cover 100 rotates, the second magnetic force F2 is weakened and the first magnetic force F1 gradually increases, but the second magnetic force F2 is always greater than the first magnetic force F1. When the first protective cover 100 rotates to the critical angle α with the housing 30, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, that is, the first protective cover 100 and the second protective cover 200 are in the first The magnetic force F1 and the second magnetic force F2 are in a balanced state under the combined action. Ideally, the first protective cover 100 and the second protective cover 200 can be in a stationary state. As the user continues to apply force to the first protective cover 100, the balance state between the first magnetic force F1 and the second magnetic force F2 is broken, so that the first magnetic force F1 is greater than the second magnetic force F2, and the user can stop applying force to the first protective cover 100 Exert force. The first magnetic force F1 can cause the first protective cover 100 and the second protective cover 200 to automatically rotate relative to the housing 30 until the first protective cover 100 and the second protective cover 200 are attached and fixed, so that the power adapter 10 is in a closed state. When the power adapter 10 is in the closed state, the first protective cover 100 and the second protective cover 200 are tightly fixed during storage or transportation, or daily placement and movement, and have the reliability of concealing the pins 60, and are thinner and convenient carry. It is understandable that when the power adapter 10 needs to be closed, the user can also choose to apply force to the second protective cover 200, and the power adapter 10 can also be closed, and the working principle is the same as that of the user applying force to the first protective cover 100 .

在一实施例中，第一保护盖100的部分或全部结构由磁性材料制成，第二保护盖200的部分或全部结构由磁性材料制成，使得第一保护盖100和第二保护盖200之间存在相互吸引的磁力。从而能够实现第一保护盖100和第二保护盖200之间的自动打开和自动闭合，且实现原理同上，在此不再赘述。In an embodiment, part or all of the structure of the first protective cover 100 is made of magnetic material, and part or all of the structure of the second protective cover 200 is made of magnetic material, so that the first protective cover 100 and the second protective cover 200 There is a magnetic force that attracts each other. Thereby, the automatic opening and automatic closing between the first protective cover 100 and the second protective cover 200 can be realized, and the realization principle is the same as the above, which will not be repeated here.
