[0020] The application will be described in further detail below with reference to the drawings and embodiments. It is to be particularly noted that the following embodiments are merely intended to illustrate the application, but not to limit the scope of the application. Similarly, the following embodiments are only some of the embodiments of the application, and all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the application.

[0021] Reference herein to "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular alternative embodiment or set of alternative embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0022] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of the adapter 10 in a closed state in some embodiments of the application, Figure 2 is Figure 1 a structural schematic view of the adapter 10 in an open state in some embodiments of the application, that is, the adapter 10 can have a closed state, i.e., a first state, as shown in Figure 1 , and an open state, i.e., a second state, as shown in Figure 2 . When the adapter 10 assumes the first state as shown in Figure 1 , the adapter 10 is convenient to carry; when the adapter 10 assumes the second state as shown in Figure 2 , the adapter 10 can be used for work.

[0023] It can be understood that all directional indications, such as up, down, left, right, front, back, etc., in the embodiments of the application are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0024] The adapter 10 generally comprises a cover body 100, a shell 200, and a hinge assembly 300 connecting the cover body 100 and the shell 200. The cover body 100 and the shell 200 are connected through the hinge assembly 300, so that the cover body 100 and the shell 200 can be relatively rotated through the hinge assembly 300, so that the adapter 10 can have a first state and a second state. In other words, the cover body 100 can be rotationally connected with the shell 200 through the hinge assembly 300.

[0025] The housing 200 may be provided with pins 11. When the adapter 10 is in the first state, the pins 11 are housed inside the adapter 10 for easy carrying; when the adapter 10 is in the second state, the pins 11 are exposed outside the adapter 10 so that the adapter 10 can work.

[0026] like Figure 1 As shown, in the first state, the cover 100 is placed over one end of the housing 200, and the pin 11 can be at least partially retracted into the cover 100, so that the cover 100 and the housing 200 cooperate to protect the pin 11 and make the adapter 10 easy to carry. Figure 2 As shown, in the second state, pin 11 is exposed on adapter 10, enabling pin 11 to be connected to an external power source, thereby enabling adapter 10 to operate.

[0027] In one embodiment, both the cover 100 and the housing 200 can be made of plastic, which is low-cost, lightweight, and has sufficient strength to protect the internal components. For example, both the cover 100 and the housing 200 can be formed by injection molding. Furthermore, the cover 100 and the housing 200 can be the same color to improve the appearance consistency of the adapter 10. In other embodiments, the cover 100 and the housing 200 can be designed in different colors to achieve different aesthetic effects. Additionally, a corresponding brand logo can be provided on the cover 100 and the housing 200 to enhance the appearance of the adapter 10 and improve brand recognition. Of course, in other embodiments, the cover 100 and the housing 200 can also be made of metal, which provides a better aesthetic texture and structural strength, although the cost is higher than that of plastic.

[0028] In one embodiment, the housing 200 is generally a cuboid or cube structure, and the edges of the housing 200 can be smoothly rounded to ensure that the adapter 10 has no protruding edges and a better feel. In other embodiments, the housing 200 can also be a cylindrical structure, an ellipsoidal shape, or other structures, without limitation. The housing 200 may have an interface, which can be located at opposite ends of the housing 200, respectively, along with the pins 11. External electronic components can be electrically connected to the adapter 10 through the interface. Of course, in other embodiments, the relative positions of the interface and the pins 11 can also be different. It is understood that the external electronic components can be intermediate connecting cables such as data cables, or electronic devices such as mobile phones, watches, tablets, or computers, or a combination of electronic devices and corresponding data cables, without specific limitations. Furthermore, the shape of the cover 100 can be adapted to the shape of the housing 200 to give the adapter 10 a better appearance.

[0029] In one embodiment, the cover 100 can include a first cover 110 and a second cover 120 connected to one end of the shell 200. In the first state, the first cover 110 and the second cover 120 are located on the same side of the shell 200, and the first cover 110 and the second cover 120 are attached to each other to accommodate the plug 11. In the second state, the first cover 110 and the second cover 120 are attached to the opposite sides of the shell 200 respectively to expose the plug 11. It should be noted that all "attached" described in the present application can be substantially attached, that is, the attachment described in the present application at least includes the following cases: in the first case, the two surfaces of the attachment are completely close without gap; in the second case, there is a gap between the two surfaces of the attachment, such as the gap between the first cover 110 and the second cover 120 and the surfaces of the opposite sides of the shell 200 is not more than 1mm or 2mm or other size, which is also within the protection scope of the present application, and the two surfaces of the attachment can be parallel or not parallel; in the third case, the two surfaces of the attachment are partially contacted, that is, the two surfaces of the attachment are not completely close, but partially close, and there is a gap between the parts.

[0030] It can be understood that the names of "first cover", "second cover" and "cover" can be converted to each other in some embodiments. For example, in one embodiment, the "first cover" in other embodiments is called "second cover" or "cover", and correspondingly, the "second cover" in other embodiments is called "first cover" or "cover".

[0031] In one embodiment, the cover 100 has a first surface 100a and a second surface 100b arranged adjacent to each other, the shell 200 has a third surface 200a and a fourth surface 200b arranged adjacent to each other, and the plug 11 extends out of the shell 200 from the third surface 200a. In the first state, the first surface 100a of the cover 100 is attached to the third surface 200a of the shell 200; in the second state, the second surface 100b of the cover 100 is attached to the fourth surface 200b of the shell 200. Preferably, in the first state, the second surface 100b is substantially flush with the fourth surface 200b; in the second state, the first surface 100a is substantially flush with the third surface 200a.

[0032] It can be understood that all "flush" described in the embodiments of the present application can also be "substantially flush", and the flush can be completely in one plane, or there can be a certain height difference within a certain range. For example, the height difference between the first surface 100a and the third surface 200a is not more than 2mm or 5mm or not more than 10mm or other size, such as not more than 1mm.

[0033] The hinge assembly 300 can be provided in multiple numbers, for example two. The first cover 110 can be rotatably connected to the housing 200 by one of the hinge assemblies 300, and the second cover 120 can be rotatably connected to the housing 200 by the other of the hinge assemblies 300. Of course, in other embodiments, the first cover 110 can be rotatably connected to the housing 200 by multiple (for example two) hinge assemblies 300, and the second cover 120 can be rotatably connected to the housing 200 by multiple (for example two) hinge assemblies 300. Hereinafter, the connection between the cover 100 and the housing 200 by one of the hinge assemblies 300 is exemplarily described.

[0034] Please refer to Figures 3 to 5 , Figure 3 is a structural schematic diagram of the cover 100 in some embodiments of the present application, Figure 4 is Figure 3 is a structural exploded schematic diagram of the cover 100 in some embodiments of the present application, Figure 5 is Figure 3 is a structural exploded schematic diagram of the cover 100 in some embodiments of the present application. The cover 100 can be the first cover 110 or the second cover 120, that is, the cover 100 (the first cover 110 or the second cover 120) can be rotatably connected to the housing 200 by the hinge assembly 300.

[0035] In an embodiment, the cover 100 can include an upper cover 111 and a lower cover 112, that is, the first cover 110 can include a first upper cover and a first lower cover, and the second cover 120 can include a second upper cover and a second lower cover. In the first state, the first cover 110 and the second cover 120 are located on the same side of the housing 200, and the first lower cover and the second lower cover are attached to each other to accommodate the plug 11. In the second state, the first cover 110 and the second cover 120 are attached to the opposite sides of the housing 200 to expose the plug 11, and the first upper cover and the second upper cover are attached to the opposite sides of the housing 200. Understandably, the names such as "first upper cover", "second upper cover" and "upper cover" can be converted to each other in some embodiments. For example, in an embodiment, the "first upper cover" in other embodiments is referred to as "second upper cover" or "upper cover", and correspondingly, the "second upper cover" in other embodiments is referred to as "first upper cover" or "upper cover". Similarly, the names such as "first lower cover", "second lower cover" and "lower cover" can be converted to each other in some embodiments.

[0036] The cover 100 is provided with a first assembly groove 101 communicating with the surface of the cover 100, and the hinge assembly 300 comprises a first rotating shaft 310 rotationally connected with the groove wall of the first assembly groove 101. The first rotating shaft 310 can be arranged in / inserted into the groove wall of the first assembly groove 101 and can rotate relative to the cover 100, so that the rotationally connecting of the cover 100 and the shell 200 is realized by the hinge assembly 300. The groove wall of the first assembly groove 101 can be provided with a first rotating shaft hole 311, and the first rotating shaft 310 is inserted into the first rotating shaft hole 311 and can rotate relative to the first rotating shaft hole 311.

[0037] The applicant found in the research that when the cover 100 is subjected to an external force (the external force generally refers to an action force other than the normal rotation of the cover 100 relative to the shell 200, for example, an action force such as a torsion force that causes the cover 100 to twist relative to the shell 200 or a pushing force, a pulling force or a pressure applied to the cover 100), that is, when the cover 100 is subjected to an action force such as a torsion force that causes the cover 100 to twist relative to the shell 200 or a pushing force, a pulling force or a pressure applied to the cover 100, the first rotating shaft 310 will exert a force on the hole wall of the first rotating shaft hole 311. Based on the fact that there is a weak area between the first rotating shaft hole 311 and the edge of the groove wall of the first assembly groove 101, the stress is more likely to cause cracking and other phenomena.

[0038] For example, in some adapters and flip electronic products, due to the need for overall structural layout, the minimum thickness of the edge of the first rotating shaft hole 311 and the edge of the groove wall of the first assembly groove 101 is only about 0.5 mm, and when the cover 100 is subjected to an action force such as a torsion force, a pushing force, a pulling force or a pressure, the groove wall area corresponding to the minimum thickness is prone to cracking and other phenomena. It can be understood that, based on the lightness and thinness of the product and cost considerations, the groove wall of the first assembly groove 101 is generally made of plastic material, so when the structural strength is not enough, the stress is prone to cracking and other phenomena.

[0039] Therefore, the applicant found through research that when at least part of the groove wall of the first assembly groove 101 is made of metal material, the cracking and other phenomena of the groove wall area corresponding to the minimum thickness can be effectively avoided. For example, in an embodiment, the area of the groove wall of the first assembly groove 101 adjacent to the outer periphery of the first rotating shaft hole 311 is made of metal material, that is, the inner wall of the first rotating shaft hole 311 and the peripheral area extending to the first rotating shaft hole 311 can be made of metal material, so that the cracking and other phenomena of the groove wall area corresponding to the minimum thickness can be avoided. At this time, the metal structure can be formed on the inner wall and the peripheral area of the first rotating shaft hole 311 by injection molding or other methods.

[0040] Of course, in other embodiments, the groove wall of the first assembly groove 101 can be entirely made of metal material to strengthen the overall structural strength of the first assembly groove 101.

[0041] Further, in some embodiments, the first rotating shaft 310 can be a metal rotating shaft. When the metal rotating shaft works with the first assembly slot 101, the metal rotating shaft and the metal material of the first assembly slot 101 can generate an abnormal sound, which can affect the user experience to some extent. Of course, when the first rotating shaft 310 is a plastic rotating shaft, the above-mentioned mode has little effect on the user experience.

[0042] In an embodiment, the first rotating shaft 310 is a metal rotating shaft, and the cavity wall of the first assembly slot 101 is a plastic material, thereby comprehensively meeting the light and thin and cost requirements of the product. And the metal rotating shaft generally has no abnormal sound when rotating with the first rotating shaft hole 311 on the plastic material.

[0043] Based on this, in order to meet the structural strength requirements of the first assembly slot 101, the first reinforcing member 410 is arranged on the slot wall of the first assembly slot 101, so as to avoid the cracking phenomenon of the area corresponding to the smaller thickness of the edge of the first rotating shaft hole 311 and the edge of the slot wall of the first assembly slot 101. Wherein, the first rotating shaft 310 can be rotatably connected with the first reinforcing member 410. That is, by arranging the first reinforcing member 410 on the slot wall of the first assembly slot 101, the ability of the first assembly slot 101 to resist damage when subjected to external force can be improved.

[0044] Wherein, the cover body 100 can be provided with a dam 130, the two opposite surfaces of the dam 130 abut against the two opposite walls of the cover body 100 respectively, and the dam 130 cooperates with the cover body 100 to form the first assembly slot 101; wherein, the dam 130 constitutes part of the slot wall of the first assembly slot 101. Specifically, the first assembly slot 101 is connected to the surface of the cover body 100, and the dam 130 is arranged in the cover body 100 and constitutes part of the slot wall of the first assembly slot 101.

[0045] Wherein, the cover body 100 can be provided with a first window 102 which communicates inside and outside of the cover body 100, the first window 102 can be arranged on the upper cover 111 or the lower cover 112, and can also be arranged on the combined part of the upper cover 111 and the lower cover 112. The person skilled in the art can flexibly select according to actual needs, and therefore will not be described here.

[0046] In an embodiment, the first window 102 is formed in the combined area of the first surface 100a and the second surface 100b, and penetrates the cover body 100 to communicate the first assembly slot 101.

[0047] As Figure 5As shown, the first surface 100a is formed on the lower cover 112, and a portion of the first window 102 penetrates the lower cover 112 and communicates with the first surface 100a; the second surface 100b is formed on the upper cover 111, and another portion of the first window 102 penetrates the lower cover 112 and communicates with the second surface 100b. In other words, one portion of the first window 102 extends from the intersection of the first surface 100a and the second surface 100b and penetrates the lower cover 112, and another portion of the first window 102 extends from the intersection of the first surface 100a and the second surface 100b and penetrates the lower cover 112.

[0048] Of course, in other embodiments, the first window 102 can be formed on the first surface 100a and penetrate the lower cover 112 to communicate with the first assembly slot 101; the first window 102 can also be formed on the second surface 100b and penetrate the upper cover 111 to communicate with the first assembly slot 101, i.e., the first assembly slot 101 communicates with the first surface 100a and the second surface 100b of the cover body 100.

[0049] The dam 130 is arranged between the upper cover 111 and the lower cover 112, and two opposite surfaces of the dam 130 abut against the upper cover 111 and the lower cover 112, respectively, i.e., the dam 130, the upper cover 111 and the lower cover 112 cooperatively form the first assembly slot 101. The first window 102 penetrates the upper cover 111 and the lower cover 112 and communicates with the first assembly slot 101.

[0050] The dam 130 is substantially in the shape of a "n" and surrounds the outer periphery of the first window 102. Two opposite surfaces of the dam 130 abut against the upper cover 111 and the lower cover 112, respectively, to form the first assembly slot 101 which communicates with the first surface 100a and / or the second surface 100b of the cover body 100.

[0051] The first rotating shaft 310 can penetrate the dam 130 and rotate relative to the dam 130, so as to realize the rotating connection between the cover body 100 and the shell 200 through the hinge assembly 300.

[0052] Please refer to Figure 6 and Figure 7 , Figure 6 is Figure 4 the partial structure of the area A in the embodiment, Figure 7 is the structure of the first reinforcing member 410 in some embodiments of the present application.

[0053] The dam 130 can be provided with a first reinforcing member 410, which has a material that has a capability of resisting damage when subjected to an external force that is superior to that of the dam 130. For example, the first reinforcing member 410 has an elastic modulus that is superior to that of the dam 130, and / or the first reinforcing member 410 has a tensile strength that is superior to that of the dam 130, and / or the first reinforcing member 410 has a torsional strength that is superior to that of the dam 130. In other words, the first reinforcing member 410 and the dam 130 satisfy at least one of the following conditions: the first reinforcing member 410 has an elastic modulus that is superior to that of the dam 130, the first reinforcing member 410 has a tensile strength that is superior to that of the dam 130, and the first reinforcing member 410 has a torsional strength that is superior to that of the dam 130. The elastic modulus is a measure of the ability of an object to resist elastic deformation, and the greater the value, the greater the stress required to produce a given elastic deformation in the material. The tensile strength is the maximum stress a material can withstand while being stretched before breaking or the point at which a material yields to a deforming force. The torsional strength is a measure of the stress an object can withstand before breaking when subjected to a twisting force, i.e., the maximum shear stress an object can withstand before breaking when subjected to a twisting force.

[0054] The material of the first reinforcing member 410 can be metal, and the material of the dam 130 can be plastic. The first rotating shaft 310 can be rotatably connected to the first reinforcing member 410. Of course, in other embodiments, the material of the first reinforcing member 410 can be plastic or other materials that have a capability of resisting damage when subjected to an external force that is superior to that of the dam 130.

[0055] The first reinforcing member 410 can have a bracket-like structure and be attached to the dam 130. The first rotating shaft 310 can pass through the dam 130 and the first reinforcing member 410. The first reinforcing member 410 can be attached to the surface or inside of the dam 130 by an insert injection molding process. Of course, the first reinforcing member 410 can also be attached to the inside or outside of the dam 130 by bonding, screwing, or other connection methods.

[0056] In an embodiment, the dam 130 comprises a first dam body 131 and a second dam body 132 arranged oppositely, a third dam body 133 arranged between the first dam body 131 and the second dam body 132, and the opposite ends of the third dam body 133 are respectively connected to the first dam body 131 and the second dam body 132 by bending. One end of the first rotating shaft 310 is rotatably connected to the first dam body 131, and / or the other end of the first rotating shaft 310 is rotatably connected to the second dam body 132. The first reinforcing member 410 can comprise a first reinforcing portion 411 arranged on the first dam body 131, a second reinforcing portion 412 arranged on the second dam body 132, and a third reinforcing portion 413 arranged on the third dam body 133, and the opposite ends of the third reinforcing portion 413 are respectively connected to the first reinforcing portion 411 and the second reinforcing portion 412 by bending.

[0057] Preferably, one end of the first rotating shaft 310 is arranged through the first dam body 131 and the first reinforcing portion 411 arranged on the first dam body 131, and the other end of the first rotating shaft 310 is arranged through the second dam body 132 and the second reinforcing portion 412 arranged on the second dam body 132.

[0058] For reference, Figure 8 and Figure 9 , Figure 8 is Figure 5 an enlarged schematic view of the local structure of the B area in an embodiment, Figure 9 is a schematic view of the structure of the connection between the cover 100 and the hinge assembly 300 in some embodiments of the present application. The cover 100 is arranged to abut at least one of the two opposite walls of the dam 130, and the first reinforcing member 410 is arranged with a clamping portion 104 capable of cooperating with the fixing portion 103. The fixing portion 103 and the clamping portion 104 cooperate to position the first reinforcing member 410, and can transmit the stress of the first reinforcing member 410 to the cover 100 to avoid stress concentration, thereby improving the strength of resistance to torsion or tension. As described above, the dam 130 is arranged between the upper cover 111 and the lower cover 112, and the two opposite surfaces of the dam 130 abut the upper cover 111 and the lower cover 112 respectively. The fixing portion 103 is arranged on the side of the upper cover 111 close to the dam 130, and / or the fixing portion 103 is arranged on the side of the lower cover 112 close to the dam 130.

[0059] In one embodiment, a fixing part 103 is disposed on the side of the upper cover 111 near the dam 130. The fixing part 103 has a shape similar to that of the dam 130 and is spaced apart from it. A first reinforcing member 410 is disposed between the dam 130 and the fixing part 103. A locking part 104 is disposed on the first reinforcing member 410 and extends from the first reinforcing member 410 toward the fixing part 103, so that the locking part 104 can cooperate with the fixing part 103 to limit and fix the first reinforcing member 410. Multiple locking parts 104 may be provided, and each locking part 104 cooperates with the fixing part 103 to limit and fix the first reinforcing member 410. As mentioned above, the dam 130 is approximately "U"-shaped, and correspondingly, the fixing part 103 is also approximately "U"-shaped.

[0060] Of course, in other embodiments, the fixing part 103 can be a fixing post or other structure provided on the upper cover 111, so as to be able to cooperate and connect with the engaging part 104.

[0061] In one embodiment, the fixing part 103 generally includes a first fixing wall 103a, a second fixing wall 103b, and a third fixing wall 103c disposed opposite to each other.

For example, the transition between the bottom wall 211 and the side wall 212 can be smooth with a chamfer, or it can be smooth without a chamfer. The receiving groove 12 can be configured to accommodate electronic devices and circuit boards and other structural components of the adapter 10.

[0068] The second housing 220 covers the opening of the receiving groove 12 and seals the internal space of the receiving groove 12, so that a relatively closed internal space is formed inside the housing 200, thereby ensuring that external water vapor and dust do not spread into the internal space of the housing 200, thus ensuring the working environment of the electronic devices and circuit boards and other structural components inside the adapter 10. The prongs 11 are inserted into the second housing 220 and electrically connected to the electronic devices or circuit boards in the receiving groove 12. The second housing 220 can be at least partially embedded in the receiving groove 12 of the first housing 210 and connected to the first housing 210.

[0072] Specifically, the housing 200 is provided with a second assembly groove 201 communicating to the surface of the housing 200, and the hinge assembly 300 includes a second rotating shaft 320 connected to the groove wall of the second assembly groove 201. Preferably, the second rotating shaft 320 is rotationally connected to the groove wall of the second assembly groove 201. The second rotating shaft 320 can be provided through the groove wall of the second assembly groove 201 and can rotate relative to the housing 200, so as to realize the rotational connection between the cover 100 and the housing 200 by the hinge assembly 300.

[0073] As described above, the housing 200 has a third surface 200a and a fourth surface 200b arranged adjacent to each other, and the pin 11 extends out of the housing 200 from the third surface 200a. The third surface 200a is formed on the second housing 220, and the fourth surface 200b is formed on the first housing 210.

[0074] In an embodiment, the second housing 220 further includes a fifth surface 200c adjacent to the third surface 200a. When the second housing 220 is covered at the opening of the receiving groove 12, the third surface 200a is arranged generally flush with the opening plane of the receiving groove 12, and the fifth surface 200c is exposed to the outside of the first housing 210 from the fourth surface 200b adjacent to the third surface 200a. In other words, the side wall 212 of the first housing 210 is provided with a second window 202 communicating with the receiving groove 12 adjacent to the area of the opening of the receiving groove 12, that is, the second window 202 extends from the edge of the fourth surface 200b adjacent to the opening of the receiving groove 12 and penetrates the side wall 212.

[0075] The slot of the second assembly groove 201 is formed at the joint area of the third surface 200a and the fifth surface 200c, and is communicated to the outside of the shell 200, i.e. the second assembly groove 201 is communicated to the third surface 200a and the fourth surface 200b of the shell 200. Among them, the third surface 200a is recessed to form part of the second assembly groove 201 at the joint area with the fifth surface 200c, the fifth surface 200c is recessed to form another part of the second assembly groove 201 at the joint area with the third surface 200a, and the part of the second assembly groove 201 formed on the third surface 200a and the other part of the second assembly groove 201 formed on the fifth surface 200c are communicated. In other words, one part of the second assembly groove 201 extends from the joint of the third surface 200a and the fifth surface 200c and is formed on the third surface 200a, and the other part extends from the joint of the third surface 200a and the fifth surface 200c and is formed on the fifth surface 200c, so that the slot of the second assembly groove 201 is exposed to the outside of the shell 200.

[0076] It should be noted that all "adjacent", "adjacent" or "adjacent" described in the present application at least include the following cases: the first case, the two surfaces of "adjacent", "adjacent" or "adjacent" are completely close without gap; the second case, there is a gap between the two surfaces of "adjacent", "adjacent" or "adjacent", such as the gap between the third surface 200a and the fourth surface 200b is not greater than 1mm or 2mm or other size, and such case is also within the protection scope of the present application, and the two surfaces of "adjacent", "adjacent" or "adjacent" can be parallel or not parallel; the third case, the two surfaces of "adjacent", "adjacent" or "adjacent" are partially contacted, i.e. the two surfaces of "adjacent", "adjacent" or "adjacent" are not completely close, but partially close, and there is a gap between the two surfaces.

[0077] In an embodiment, the hinge assembly 300 can further include a shaft seat 330 inserted into the first assembly groove 101 at one end and the second assembly groove 201 at the other end, i.e. one end of the shaft seat 330 is inserted into the first assembly groove 101, and the end of the shaft seat 330 away from the first assembly groove 101 is inserted into the second assembly groove 201. Among them, the first shaft 310 and the second shaft 320 are respectively threaded through the opposite ends of the shaft seat 330, and at least one of the first shaft 310 and the second shaft 320 can rotate relative to the shaft seat 330.

[0078] Of course, in other embodiments, the first rotating shaft 310 and the second rotating shaft 320 are respectively connected to opposite ends of the rotating shaft seat 330 and respectively pass through / insert into the slot wall of the first assembly slot 101 and the second assembly slot 201, so that at least one of the first rotating shaft 310 and the second rotating shaft 320 can rotate relative to the first assembly slot 101 and the second assembly slot 201, thereby enabling the cover body 100 to rotate relative to the shell 200. The first rotating shaft 310 can be fixedly connected with the rotating shaft seat 330, and / or the second rotating shaft 320 can be fixedly connected with the rotating shaft seat 330.

[0079] The first rotating shaft 310 and the second rotating shaft 320 are arranged in parallel, i.e., the axes of the first rotating shaft 310 and the second rotating shaft 320 are parallel. The cover body 100 can rotate around the first rotating shaft 310, and / or the shell 200 can rotate around the second rotating shaft 320. Of course, the rotating shaft seat 330 can rotate around the first rotating shaft 310 and / or the second rotating shaft 320.

[0080] Please refer to Figure 13 , Figure 13 is a partial structural schematic diagram of the shell 200 in some embodiments of the present application. The slot wall of the second assembly slot 201 is provided with a second reinforcing member 420, and the second rotating shaft 320 is connected with the second reinforcing member 420. Preferably, the second rotating shaft 320 is rotationally connected with the second reinforcing member 420. In other words, the second rotating shaft 321 passes through the second reinforcing member 420 and the slot wall of the second assembly slot 201.

[0081] In an embodiment, the region of the slot wall of the second assembly slot 201 adjacent to the outer periphery of the second rotating shaft hole 321 is made of metal material, i.e., the inner wall of the second rotating shaft hole 321 and the peripheral region extending to the second rotating shaft hole 321 can be made of metal material, so as to improve the ability of the second assembly slot 201 to resist damage when subjected to external force. At this time, the metal structure can be formed on the inner wall and the peripheral region of the second rotating shaft hole 321 by injection molding or the like.

[0082] Of course, in other embodiments, the slot wall of the second assembly slot 201 can be entirely made of metal material, so as to strengthen the overall structural strength of the second assembly slot 201.

[0083] In some embodiments, the second rotating shaft 320 can be a metal rotating shaft. When the metal rotating shaft works with the second assembly slot 201, the metal rotating shaft and the metal material of the second assembly slot 201 can produce an abnormal sound, which will affect the user experience to some extent. Of course, when the second rotating shaft 320 is a plastic rotating shaft, the above-mentioned mode has little effect on the user experience.

[0084] In an embodiment, the second rotating shaft 320 is a metal rotating shaft, and the cavity wall of the second assembly slot 201 is made of plastic material, so as to comprehensively meet the lightness, thinness and cost requirements of the product. In addition, the metal rotating shaft generally does not produce abnormal sound when rotating with the second rotating shaft hole 321 made of plastic material.

[0085] Based on this, in order to meet the structural strength requirements of the second assembly slot 201, the second reinforcing member 420 is arranged on the slot wall of the second assembly slot 101 in the embodiment, so as to avoid the cracking phenomenon of the area corresponding to the smaller thickness of the edge of the second rotating shaft hole 321 and the edge of the slot wall of the second assembly slot 201. The second rotating shaft 320 can be rotationally connected with the second reinforcing member 420. That is, the second reinforcing member 420 arranged on the slot wall of the second assembly slot 201 can improve the ability of the second assembly slot 201 to resist damage when subjected to external force.

[0086] The material of the second reinforcing member 420 has a better ability to resist damage when subjected to external force than the material of the slot wall of the second assembly slot 201. For example, the elastic modulus of the second reinforcing member 420 is better than the elastic modulus of the slot wall of the second assembly slot 201, and / or the tensile strength of the second reinforcing member 420 is better than the tensile strength of the slot wall of the second assembly slot 201, and / or the torsional strength of the second reinforcing member 420 is better than the torsional strength of the slot wall of the second assembly slot 201. In other words, the second reinforcing member 420 and the slot wall of the second assembly slot 201 meet at least one of the following conditions: the elastic modulus of the second reinforcing member 420 is better than the elastic modulus of the slot wall of the second assembly slot 201, the tensile strength of the second reinforcing member 420 is better than the tensile strength of the slot wall of the second assembly slot 201, and the torsional strength of the second reinforcing member 420 is better than the torsional strength of the slot wall of the second assembly slot 201. The elastic modulus is a measure of the ability of an object to resist elastic deformation, and the larger the value, the greater the stress required to cause a certain elastic deformation of the material. The tensile strength is a critical value for the transition from uniform plastic deformation to local concentrated plastic deformation of an object, and is also the maximum load capacity of the object under static tension. The tensile strength represents the resistance of the maximum uniform plastic deformation of the material. The torsional strength is a measure of the stress of an object resisting torsional failure, that is, the maximum shear stress corresponding to the maximum torque of the object is the torsional strength of the object.

[0087] For example, the material of the second reinforcing member 420 can be metal, and the material of the slot wall of the second assembly slot 201 can be plastic. Of course, in other embodiments, the material of the second reinforcing member 420 can be plastic or other materials, and the ability of the material to resist damage when subjected to external force is better than the ability of the material of the slot wall of the second assembly slot 201 to resist damage when subjected to external force.

[0088] In an embodiment, the second reinforcing member 420 can be in a sheet structure and attached to the wall of the second assembly groove 201. The second reinforcing member 420 can be attached to the surface or inside of the wall of the second assembly groove 201 by insert injection molding, or can be attached to the inside or outside of the wall of the second assembly groove 201 by bonding, screwing, or other connection methods.

[0089] The second assembly groove 201 generally includes oppositely arranged first and second groove walls 201a and 201b, and the second rotating shaft 320 is rotatably connected to the first groove wall 201a and / or the second groove wall 201b. At least one of the first and second groove walls 201a and 201b is provided with a second reinforcing member 420. Specifically, the second rotating shaft 320 can be inserted into or through the first groove wall 201a and rotatably connected to the first groove wall 201a, and / or the second rotating shaft 320 can be inserted into or through the second groove wall 201b and rotatably connected to the second groove wall 201b. The first groove wall 201a is provided with a second reinforcing member 420, the second rotating shaft 320 is inserted into the first groove wall 201a and the second reinforcing member 420 provided on the first groove wall 201a, and / or the second groove wall 201b is provided with a second reinforcing member 420, and the second rotating shaft 320 is inserted into the second groove wall 201b and the second reinforcing member 420 provided on the second groove wall 201b. Preferably, the first and second groove walls 201a and 201b are each provided with a second reinforcing member 420, i.e., two second reinforcing members 420 are provided and each in a sheet shape. One end of the second rotating shaft 320 is inserted into the first groove wall 201a and the second reinforcing member 420 provided on the first groove wall 201a, and the other end of the second rotating shaft 320 is inserted into the second groove wall 201b and the second reinforcing member 420 provided on the second groove wall 201b.

[0090] It can be understood that the second reinforcing member 420 has technical features not described in detail, which can refer to the related technical features of the first reinforcing member 410, and thus will not be described in detail.

[0091] In addition, in order to further illustrate the ability of the adapter provided by the above-mentioned embodiments of the present application to improve its resistance to damage when subjected to external forces, a super-thin cover adapter similar to a biscuit is taken as an example, which has the characteristics of light weight and thin thickness. For example, a recently released cover biscuit charger or adapter with a weight of about 100 grams and a thickness of about 15 mm.

[0092] The adapter prong contacts strong current during insertion into the socket, and the operation process has certain safety risks, so it needs to meet relevant safety requirements. Based on the structural characteristics of the above-mentioned super-thin adapter, if the cover body and the shell are separated, the creepage distance of the prong root generally cannot meet the relevant safety requirements at this time, and in this case, the user has a safety risk.

[0093] Therefore, the cover can meet the product safety requirement without being damaged by human force applied to the cover without the aid of tools. In order to verify the force that can be borne by the ultra-thin adapter, a classification test is performed on the type of force applied to the cover. It is found that, when a twisting force is applied to the cover, the damage to the cover is the strongest, and the structural strength of each part of the cover can be comprehensively investigated. Meanwhile, based on the structure of the ultra-thin adapter, the twisting force can be considered as the most convenient force applied by hand. Therefore, the torsional strength of the cover can be used as an important index for measuring the damage resistance of the ultra-thin adapter.

[0094] It can be understood that the human strength characteristics generally conform to the normal distribution. Based on the structure of the ultra-thin adapter, it is found through tests that the average value of the torque that can be output by an adult man by hand is about 3.3 N·m, and the standard deviation is about 0.76 N·m. Therefore, the sum of the average value and 3 times the standard deviation is about 5.6 N·m. In order to further ensure safety, a safety factor of 1.2 can be given, that is, 6.72 N·m. According to this normal distribution, the probability of a torque of 6.72 N·m is about 1.88 PPM, that is, about 1.88 out of every million people can reach a torque of 6.72 N·m by hand. Therefore, it can be considered that a torsional strength of 7 N·m is sufficient to meet the probability that the cover is damaged by hand approaching 0, and therefore, 7 N·m can be set as the target value of the torsional strength of the cover.

[0095] As known from the adapter structure in the foregoing embodiments, there is a weakest part between the edge of the slot wall of the shaft hole and the assembly slot, that is, the minimum thickness from the shaft hole to the outer edge of the slot wall is about 0.6 mm to meet the light and thin requirement, and cracking is more likely to occur under external force. It is found through measurement that the maximum torque that can be borne by the cover under this structure is about 3 N·m, which is obviously far from the target value of the torsional strength of the cover.

[0096] The foregoing embodiments of the present application set the reinforcing member, so that the torsional force can be borne by the reinforcing member and the cover together, and the torsional force can be evenly distributed in all directions, so that stress concentration can be avoided, thereby a large torsional strength can be generated. It is found through actual measurement that the torsional strength of the cover of the adapter provided by the foregoing embodiments of the present application can exceed 7 N·m.

[0097] It can be understood that the foregoing only uses the ultra-thin adapter as a test for verification, and the foregoing structure also has obvious torsional effect for conventional adapters of the same type or similar structure.

[0098] The adapter provided by the embodiments of the present application can obviously improve the ability of the first assembly groove to resist damage when subjected to external force by arranging the first reinforcing member on the groove wall of the first assembly groove, or by manufacturing at least part of the groove wall of the first assembly groove from metal material, thereby improving the torsional strength of the cover body. In addition, the first assembly groove is arranged in the cover body, the first reinforcing member is connected with the cover body and / or the shell, the stress of the first assembly groove can be transmitted to the cover body through the first reinforcing member to achieve sharing, thereby avoiding stress concentration and being able to produce greater torsional strength. Similarly, by arranging the second reinforcing member on the groove wall of the second assembly groove, the ability of the second assembly groove to resist damage when subjected to external force can be improved, thereby improving the torsional strength of the shell.

[0099] In addition, the first reinforcing member and / or the second reinforcing member can be made of metal material and can be formed by stamping, which is low in cost. At the same time, the first reinforcing member and / or the second reinforcing member exist as a protective structure of the adapter, only play the corresponding role of the metal rotating shaft and the plastic rotating shaft hole in the conventional normal use process, and can avoid the abnormal sound generated by the friction of the metal rotating shaft with other metal structures during rotation. When the cover body and / or the shell are subjected to a large torsional force, the first reinforcing member and / or the second reinforcing member play a role to avoid damage.

[0100] It should be noted that the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed or can optionally include other steps or units inherent to these processes, methods, products or settings.

[0101] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
