Description

Technical Field

[0001] This application relates to the field of mobile power bank technology, and more particularly to a mobile power bank. Background Technology

[0002] In related technologies, the power bank integrates a charging terminal that can rotate around the power bank, extending out of the power bank when charging is needed and retracting into the power bank when charging is not needed. However, mobile phone charging ports are usually located at the bottom. When the phone is plugged into the charging terminal, the charging terminal or power bank only contacts the bottom of the phone, resulting in poor support for the phone and thus poor stability of the power bank in supporting the phone during charging. Utility Model Content

[0003] This application provides a portable power bank that can enhance the support for mobile phones and improve the stability of mobile phones during charging.

[0004] In a first aspect, embodiments of this application provide a portable power bank, which includes a first housing, a battery, a circuit board, a second housing, a connecting terminal, an electrical connection assembly, a first rotating structure, and a second rotating structure. The circuit board is electrically connected to the battery, and both the battery and the circuit board are disposed within the first housing. The connecting terminal is disposed in the second housing and has an input terminal and an output terminal. The electrical connection assembly electrically connects the input terminal of the connecting terminal and the circuit board. The portable power bank has a first state, in which the output terminal of the connecting terminal faces the first housing. The first rotating structure connects the connecting terminal to the second housing, allowing the connecting terminal to rotate relative to the second housing. The second rotating structure connects the first housing to the second housing, allowing the first housing to rotate relative to the second housing.

[0005] Beneficial effects: Since the first housing can rotate relative to the second housing through the first rotating structure, and the connecting terminal can rotate relative to the second housing through the second rotating structure, when charging is required, the first housing can be rotated to form an angle with the second housing, and the connecting terminal can be rotated to be approximately parallel to the first housing. When the electronic device is plugged into the connecting terminal, the first housing can abut against the front or back of the electronic device, thereby providing support for the electronic device. This makes the mobile power supply provide high stability for the electronic device during charging. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0026] Furthermore, the use of terms such as "first," "second," etc., in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] Furthermore, the technical solutions of the various embodiments of this application can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this application.

[0029] like Figures 1-5 As shown, the first aspect of this application provides a mobile power supply 100 including a first housing 110, a battery 120, a circuit board 130, a second housing 140, a connection terminal 150, an electrical connection assembly 160, a first rotating structure 170, and a second rotating structure 180.

[0030] Battery 120 is used to store electrical energy, which can then be released when needed. The type of battery 120 can be, for example, a steel-cased battery 120 or a pouch battery 120. The shape of battery 120 can be, for example, cylindrical, square, etc., and the capacity of battery 120 can be, for example, any value between 2000mAh and 30000mAh. Circuit board 130 is electrically connected to battery 120. Circuit board 130 is a charging and discharging circuit board adapted to power bank 100, and a charging management chip is built into circuit board 130. Circuit board 130 is used to control the charging and discharging of battery 120. For example, the charging management chip and related circuits on circuit board 130 can perform operations such as charging, discharging, power detection, and voltage detection on battery 120. It can also have protection functions such as overcharge, over-discharge, overcurrent, temperature control, and short-circuit protection, thereby extending the service life of battery 120 and improving the safety of battery 120 during use.

[0031] Both the battery 120 and the circuit board 130 are housed within a hollow first housing 110. The first housing 110 can limit and fix the battery 120 and the circuit board 130, and at the same time, it can protect the battery 120 and the circuit board 130. The first housing 110 can be made of plastic, which allows for the manufacture of complex shapes at a relatively low cost and provides insulation. Alternatively, the first housing 110 can be made of metal, giving it high strength and a long service life. The first housing 110 can be plate-shaped, resulting in a relatively thin profile.

[0032] like Figure 2 As shown, the connection terminal 150 has an input terminal 151 and an output terminal 152 connected to the input terminal 151. The output terminal 152 of the connection terminal 150 is used to connect to an electronic device to supply power to the electronic device. The electronic device can be, for example, a mobile phone, wireless headphones, a tablet, etc. The type of the connection terminal 150 can be, for example, USB Type-C, Lightning, Micro USB, etc. The connection terminal 150 is disposed in a second housing 140, which is used to mount and protect the connection terminal 150. The material of the second housing 140 can be, for example, plastic, which allows for the manufacture of complex shapes at a relatively low cost and provides insulation. The material of the second housing 140 can be, for example, metal, which provides high strength and a long service life. The shape of the second housing 140 can be, for example, plate-like, resulting in a relatively thin thickness. When the power bank is in use, the output terminal 152 of the connection terminal 150 extends at least partially outward relative to the second housing 140 to electrically connect to an external electronic device, thereby providing power.

[0033] Electrical connection assembly 160 electrically connects the input terminal 151 of connection terminal 150 and circuit board 130, so that the electrical energy stored in battery 120 can be conducted to connection terminal 150 through circuit board 130 and electrical connection assembly 160. Electrical connection assembly 160 can be a flexible circuit or a wire. Electrical connection assembly 160 can be soldered to circuit board 130 or connection terminal 150, or it can be plugged into circuit board 130 or connection terminal 150 via ribbon cable connector.

[0034] The first rotating structure 170 connects the connecting terminal 150 to the second housing 140, allowing the connecting terminal 150 to rotate relative to the second housing 140. When charging is required, the connecting terminal 150 can be rotated to form an angle with the second housing 140, facilitating the insertion and engagement of the electronic device with the connecting terminal 150. The angle between the connecting terminal 150 and the second housing 140 can, for example, be greater than or equal to 0 degrees and less than or equal to 90 degrees. When charging is not required, the connecting terminal 150 can be rotated to fit snugly against the second housing 140, thereby reducing the protrusion of the connecting terminal 150 relative to the second housing 140, making the power bank 100 easier to carry and reducing the probability of the connecting terminal 150 being scratched. Figure 1 As shown, optionally, the second housing 140 is provided with a groove 140b, and the connection terminal 150 can be at least partially housed in the groove 140b, or can extend out from the groove 140b when the power bank is in the second state, thereby making the outer surface of the second housing 140 relatively flat, further improving the portability of the power bank 100, further reducing the probability of the connection terminal 150 being scratched by external objects, and the connection terminal 150 being at least partially hidden in the second housing 140, resulting in better safety.

[0035] The second rotating structure 180 connects the first housing 110 and the second housing 140, allowing the first housing 110 to rotate relative to the second housing 140. Optionally, the second rotating structure 180 is positioned between the first housing 110 and the first rotating structure 170 along the length of the first housing. When charging is required, the first housing 110 can be rotated to form an angle with the second housing 140, and the connecting terminal 150 can be rotated to be approximately parallel to the first housing 110. When the electronic device is plugged into the connecting terminal 150, the first housing 110 can abut against the front or back of the electronic device, providing support and thus ensuring high stability during charging. Furthermore, since the first housing 110 can abut against the front or back of the electronic device, meaning the first housing 110 and the electronic device can be stacked, the overall assembly size of the electronic device and the power bank 100 during charging is small, occupying a relatively neat space, making it convenient to carry. When not in use for charging, the first housing 110 can be rotated to be parallel to the second housing 140, so that the power bank 100 has a more regular shape and an integrated design, making it easy to carry and less likely to be scratched by other external objects.

[0036] In some embodiments, the power bank 100 further includes a reset member connected to the connection terminal 150 and the second housing 140, or the reset member connected to the first rotating structure 170 and the second housing 140, so that the connection terminal 150 has a restoring force to rotate to be parallel to the second housing 140. When the user pries the connection terminal 150 by hand, the user needs to overcome the elastic force of the reset member, and when the user releases the user, the connection terminal 150 can be reset to be parallel to the second housing 140.

[0037] The reset element can be, exemplarily, a torsion spring, with its two arms connected to the connecting terminal 150 and the second housing 140 respectively, thereby pushing the connecting terminal 150 to rotate and reset. Alternatively, the reset element can be a spring plate, with both ends connected to the connecting terminal 150 and the second housing 140 respectively, thereby pushing the connecting terminal 150 to rotate and reset.

[0038] like Figures 1-5 As shown, in some embodiments, the power bank 100 has a first state and a second state, such as... Figures 1-3 As shown, the power bank 100 is in the first state, as... Figure 4 and Figure 5 As shown, when the power bank 100 is in the second state, and the power bank 100 rotates from the first state to the second state, the angle between the first housing 110 and the second housing 140 decreases. For example, the angle between the first housing 110 and the second housing 140 changes from 180 degrees to 90 degrees. It should be noted that when the power bank 100 rotates from the first state to the second state, the connecting terminal 150 can rotate or remain stationary relative to the second housing 140. That is, the angle between the connecting terminal 150 and the second housing 140 can change or remain unchanged. In other words, when the power bank 100 is in the second state, the angle between the connecting terminal 150 and the second housing 140 can be 0 degrees, 90 degrees, or any angle between 0 and 90 degrees.

[0039] Optionally, such as Figures 1-3 As shown, the power bank 100 is in a first state, with the first housing 110 parallel to the second housing 140. In this embodiment, "parallel" includes the case where both are on the same plane. Optionally, the first housing 110 and the second housing 140 are substantially on the same plane, that is, the front of the first housing 110 is substantially flush with the front of the second housing 140, and the back of the first housing 110 is substantially flush with the second housing 140. Figure 3 and Figure 4As shown, the power bank 100 is in the second state, with the first housing 110 perpendicular to the second housing 140 and the connecting terminal 150 parallel to the first housing 110. Since the charging port of electronic devices such as mobile phones is usually parallel to the back of the device and located at the bottom, when the connecting terminal 150 is plugged into the charging port of the mobile phone or other electronic device, the first housing 110 is parallel to the back of the phone, which helps the first housing 110 support the electronic device.

[0040] Optionally, when the connecting terminal 150 is rotated to be approximately parallel to the first housing 110, the distance between the connecting terminal 150 and the first housing 110 is approximately the same as the thickness between the charging port and the back of the electronic device. This allows the electronic device to precisely fill the gap between the connecting terminal 150 and the first housing 110, further improving the support performance of the first housing 110 for the electronic device. The distance between the connecting terminal 150 and the first housing 110 can be any value between 2mm and 20mm.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, when the power bank 100 is in the first state, the connection terminal 150 is positioned toward the first housing 110, that is, the input end 151 of the connection terminal 150 can rotate, and the input end 151 of the connection terminal 150 is positioned away from the first housing 110, so that the first rotating structure 170 can be arranged away from the first housing 110, thereby reducing the difficulty of arrangement.

[0042] Optionally, the output end 152 of the connection terminal 150 can be positioned as close as possible to the first housing 110. With a fixed length of the connection terminal 150, the distance H between the connection terminal 150 and the first housing 110 when the power bank 100 is in the second state can be reduced. For example, as... Figure 1 and Figure 3 As shown, the first housing 110 is provided with a relief groove 140c for accommodating the connection terminal 150, so that the connection terminal 150 can utilize the space of the first housing 110 to further reduce the distance H between the connection terminal 150 and the first housing 110 when the mobile power supply 100 is in the second state.

[0043] Optionally, the rotation range of the connecting terminal 150 relative to the second housing 140 is the same as the rotation range of the first housing 110 relative to the second housing 140. The rotation range of the connecting terminal 150 relative to the second housing 140 refers to the angular change experienced by the connecting terminal 150 relative to the second housing 140 during rotation or rotation. Similarly, the rotation range of the first housing 110 relative to the second housing 140 refers to the angular change experienced by the first housing 110 relative to the second housing 140 during rotation or rotation. For example, if the connecting terminal 150 rotates 90 degrees relative to the second housing 140, then the rotation range of the connecting terminal 150 relative to the second housing 140 is 90 degrees.

[0044] Optionally, the rotation direction of the connection terminal 150 relative to the second housing 140 is the same as the rotation direction of the first housing 110 relative to the second housing 140. For example, when the power bank 100 switches from the first state to the second state, that is, from... Figure 1 The state is rotated to Figure 4 When in the state, the rotation direction of the first housing relative to the second housing is clockwise, and the rotation direction of the connecting terminal relative to the second housing is also clockwise.

[0045] like Figure 6 As shown, in some embodiments, the power bank 100 further includes a linkage structure 190, which is connected to the first rotating structure 170 and the second rotating structure 180. The second rotating structure 180 can drive the first rotating structure 170 to rotate through the linkage structure 190, so that the first rotating structure 170 and the second rotating structure 180 rotate synchronously. By setting the linkage structure 190, when the first housing 110 and the second housing 140 are driven to rotate relative to each other, the connection terminal 150 can be rotated synchronously relative to the second housing 140. The user does not need to rotate the first housing 110 and the connection terminal 150 separately, saving operation steps and making the power bank 100 more convenient to use.

[0046] like Figure 6 and Figure 7As shown, in some embodiments, the linkage structure 190 includes a rigid member 191, which is exemplarily made of metal for durability. One end of the rigid member 191 is fixedly connected to the first rotating structure 170, and the other end is fixedly connected to the second rotating structure 180. When the second rotating structure 180 rotates, it drives the rigid member 191 to move, for example, by pushing or pulling the rigid member 191, which in turn drives the first rotating structure 170 to rotate. Exemplarily, when the power bank 100 rotates from the first state to the second state, the rigid member 191 deforms to pull the first rotating structure 170 to rotate. In another embodiment, when the power bank 100 rotates from the second state to the first state, the rigid member 191 recovers its deformation to push the first rotating structure 170 to rotate. In another embodiment, when the mobile power supply 100 rotates from the first state to the second state, the rigid member 191 deforms to drive the first rotating structure 170 to rotate; when the mobile power supply 100 rotates from the second state to the first state, the rigid member 191 restores its deformation to pull the first rotating structure 170 to rotate.

[0047] One end of the rigid member 191 can also be rolledly connected to the first rotating structure 170, with the rigid member 191 abutting against the first rotating structure 170 and a rolling friction force between them. When the rigid member 191 moves, it pushes the first rotating structure 170 to rotate. Alternatively, the other end of the rigid member 191 can also be rolledly connected to the second rotating structure 180, with the rigid member 191 abutting against the second rotating structure 180 and a rolling friction force between them. When the second rotating structure 180 rotates, it pushes the rigid member 191 to move.

[0048] The rigid component 191 can be bent or elastically deformed, thus it can be designed according to the shape of the internal space of the power bank 100. The rigid component 191 can be fitted to the components inside the power bank 100, thereby reducing its space occupation. For example, the rigid component 191 can be fitted to a portion of the surface of the second rotating structure 180. Optionally, creases can be pre-set on the rigid component 191 to limit the bending portion, allowing the rigid component 191 to bend in a predetermined manner. Optionally, by changing the connection position of the rigid component 191 with the first rotating structure 170 or the second rotating structure 180, the rotation directions of the first rotating structure 170 and the second rotating structure 180 can be made the same or opposite, or the speed ratio between the first rotating structure 170 and the second rotating structure 180 can be adjusted.

[0049] like Figures 6-8As shown, in some embodiments, the rigid member 191 is a sheet-like structure. The rigid member 191 is thin, occupies little space, and can pass through gaps, reducing layout complexity. In this embodiment, the rigid member 191 functions as a drive belt. The rigid member 191 has a certain rigidity and can undergo elastic deformation, thus driving the first rotating structure 170 to rotate forward or backward. Optionally, the rigid member 191 can be wound around or unwound from the first rotating structure 170, thereby reducing the space occupied by the rigid member 191 and helping to reduce the volume of the linkage structure 190. For example, the first rotating structure 170... Figure 6 Rotate to Figure 8 At that time, the rigid member 191 unfolds from the first rotating structure 170, and the first rotating structure 170 unfolds from... Figure 8 Rotate to Figure 6 At that time, the rigid member 191 partially surrounds the first rotating structure 170.

[0050] In some embodiments, the linkage structure 190 includes a first gear and a second gear. The first gear is connected to and rotates synchronously with the first rotating structure 170, and the second gear is connected to and rotates synchronously with the second rotating structure 180. The first gear and the second gear mesh. Exemplarily, the first rotating structure 170 may include a rotating shaft fixedly connected to the first gear, and the second rotating structure 180 may include a rotating shaft fixedly connected to the second gear. The first rotating structure 170 and the second rotating structure 180 are linked through the first gear and the second gear. In this case, the linkage structure 190 is fixedly connected to both the first rotating structure 170 and the second rotating structure 180.

[0051] When the first rotating structure 170 rotates, the first gear rotates along with it, while the second gear rotates in the opposite direction. That is, the first rotating structure 170 and the second rotating structure 180 rotate in opposite directions at this time. If it is necessary to make the first rotating structure 170 and the second rotating structure 180 rotate in the same direction, another gear can be placed between the first and second gears to achieve a reversal. Optionally, the gear ratio between the first gear and the second gear can be 1, so that the first rotating structure 170 and the second rotating structure 180 rotate at the same angle.

[0052] The linkage structure 190 can also be other transmission mechanisms. For example, the linkage structure 190 includes a transmission belt, a first transmission wheel is provided on the first rotating structure 170, a second transmission wheel is provided on the second rotating structure 180, and the transmission belt is sleeved on the first transmission wheel and the second transmission wheel. In this case, the linkage structure 190 is in a rolling connection with the first rotating structure 170 and the second rotating structure 180.

[0053] The linkage structure 190 may also include a crank-connecting rod mechanism, which enables the first rotating structure 170 and the second rotating structure 180 to be linked. Alternatively, the linkage structure 190, the first rotating structure 170, and the second rotating structure 180 may form a planar four-bar linkage to achieve linkage.

[0054] like Figure 8 As shown, in some embodiments, the first rotating structure 170 includes a first rotating shaft 171, a connecting terminal 150 is fixedly connected to the first rotating shaft 171, the first rotating shaft 171 is rotatably disposed on the second housing 140, and the linkage structure 190 is connected to the first rotating shaft 171 and drives the first rotating shaft 171 to rotate.

[0055] Alternatively, the connecting terminal 150 is rotatably mounted on the first rotating shaft 171, and the first rotating shaft 171 is rotatably mounted on the second housing 140 or fixedly mounted on the second housing 140. The linkage structure 190 is connected to the connecting terminal 150 and drives the first rotating shaft 171 to rotate. For example, the rigid member 191 is connected to the first rotating shaft 171, thereby directly driving the first rotating shaft 171 to rotate.

[0056] like Figure 8 As shown, in some embodiments, the first rotating structure 170 further includes a first connecting member 172 disposed on the first rotating shaft 171. The linkage structure 190 is connected to the first connecting member 172 and drives the first rotating shaft 171 to rotate through the first connecting member 172. Exemplarily, the rigid member 191 is connected to the first connecting member 172. The first connecting member 172 and the first rotating shaft 171 can be integrally formed, thereby saving assembly steps. The shape of the first connecting member 172 can be cam-shaped, which facilitates a fixed connection with the rigid member 191.

[0057] like Figure 9 As shown, in some embodiments, a receiving groove 140a is provided on the wall surface of the first housing 110, and the first rotating shaft 171 is at least partially received in the receiving groove 140a, so that the wall thickness of the second housing 140 can be used to accommodate the first rotating shaft 171, thereby reducing the size of the second housing 140.

[0058] like Figures 10-12 As shown, in some embodiments, the second rotating structure 180 includes a third housing 181, a first rotating assembly 182, and a second rotating assembly 183.

[0059] The third housing 181 is used to install the first rotating assembly 182 and the second rotating assembly 183, so that the axis of the first rotating assembly 182 is fixed relative to the axis of the second rotating assembly 183.

[0060] The first rotating component 182 is rotatably mounted on the third housing 181 and is connected to the first housing 110. Rotation of the first rotating component 182 causes the first housing 110 to rotate. Optionally, the first rotating component 182 and the first housing 110 are detachably connected, for example, by screws. This allows for assembly where the first rotating component 182 is first assembled with the third housing 181, and then the third housing 181 is assembled with the first housing 110, reducing assembly difficulty. Alternatively, the first rotating component 182 and the first housing 110 can be integrally injection molded, further reducing assembly steps.

[0061] The second rotating component 183 is rotatably mounted on the third housing 181 and connected to the second housing 140. Rotation of the second rotating component 183 causes the second housing 140 to rotate. Optionally, the second rotating component 183 and the second housing 140 are detachably connected, for example, by screws. This allows for assembly where the second rotating component 183 is first assembled with the third housing 181, and then the third housing 181 is assembled with the first housing 110, reducing assembly difficulty. Alternatively, the second rotating component 183 and the second housing 140 can be integrally injection molded, further reducing assembly steps.

[0062] By setting the first rotating component 182 and the second rotating component 183, the first housing 110 and the second housing 140 can rotate around different axes, thereby separating the first housing 110 and the second housing 140 and avoiding interference between the first housing 110 and the second housing 140 during rotation.

[0063] like Figures 10-12As shown, in some embodiments, the first rotating component 182 and the second rotating component 183 are connected in a transmission manner, meaning that the first rotating component 182 and the second rotating component 183 rotate simultaneously and remain stationary at the same time, and the rotation directions of the first rotating component 182 and the second rotating component 183 are opposite. When the first rotating component 182 rotates towards the second rotating component 183, the second rotating component 183 also rotates towards the first rotating component 182. When the first rotating component 182 rotates away from the second rotating component 183, the second rotating component 183 also rotates away from the first rotating component 182. Since both the first rotating component 182 and the second rotating component 183 are disposed in the third housing 181, that is, both the first housing 110 and the second housing 140 rotate relative to the third housing 181, and the angle of rotation of the first housing 110 relative to the third housing 181 is relatively small, and the angle of rotation of the second housing 140 relative to the third housing 181 is relatively small, it is beneficial to make the gap between the first housing 110 and the third housing 181 smaller, and the gap between the second housing 140 and the third housing 181 smaller, so as to minimize the possibility of debris falling into the power bank 100.

[0064] like Figures 10-12 As shown, in some embodiments, the first rotating assembly 182 includes a second rotating shaft 1821, a third gear 1822, and a second connecting member 1823. The second connecting member 1823 connects the third gear 1822 and the first housing 110, and the connection between the second connecting member 1823 and the first housing 110 can be a screw connection. The second rotating shaft 1821 is rotatably disposed on the third housing 181, and the third gear 1822 is fixedly connected to the second rotating shaft 1821; alternatively, the second rotating shaft 1821 is fixedly disposed on the third housing 181, and the third gear 1822 is rotatably disposed on the second rotating shaft 1821, requiring only that the third gear 1822 rotate relative to the third housing 181. The third gear 1822 and the second connecting member 1823 are connected to the third housing 181 through the second rotating shaft 1821, and the third gear 1822 and the second connecting member 1823 may not be in contact with the third housing 181. Optionally, the rigid member 191 can be connected to the second rotating shaft 1821, which can drive the rigid member 191 to move when it rotates.

[0065] The second rotating assembly 183 includes a third rotating shaft 1831, a fourth gear 1832, and a third connecting member 1833. The third connecting member 1833 connects the fourth gear 1832 and the second housing 140. The connection between the third connecting member 1833 and the second housing 140 can be a screw connection. The third rotating shaft 1831 is rotatably mounted on the third housing 181, and the fourth gear 1832 is fixedly connected to the third rotating shaft 1831; alternatively, the third rotating shaft 1831 is fixedly mounted on the third housing 181, and the fourth gear 1832 is rotatably mounted on the third rotating shaft 1831, requiring only that the fourth gear 1832 rotates relative to the third housing 181. The third gear 1822 meshes with the fourth gear 1832, thereby realizing the transmission connection between the first rotating assembly 182 and the second rotating assembly 183, and the rotation directions of the first rotating assembly 182 and the second rotating assembly 183 are opposite. The fourth gear 1832 and the third connecting member 1833 are connected to the third housing 181 via the third rotating shaft 1831. The fourth gear 1832 and the third connecting member 1833 may not be in contact with the third housing 181. Optionally, the rigid member 191 may be connected to the third rotating shaft 1831, and the third rotating shaft 1831 may drive the rigid member 191 to move when it rotates.

[0066] like Figures 10-12 As shown, in some embodiments, the second rotating structure 180 further includes a third rotating component 188 and a fourth rotating component 189.

[0067] The third housing 181 is used to install the third rotating assembly 188 and the fourth rotating assembly 189, so that the axis of the third rotating assembly 188 is fixed relative to the axis of the fourth rotating assembly 189.

[0068] The third rotating component 188 is rotatably mounted on the third housing 181 and connected to the first housing 110. Rotation of the third rotating component 188 causes the first housing 110 to rotate. Optionally, the third rotating component 188 and the first housing 110 are detachably connected, for example, by screws. This allows for assembly where the third rotating component 188 and the third housing 181 are assembled first, followed by the assembly of the third housing 181 and the first housing 110, reducing assembly difficulty. Alternatively, the third rotating component 188 and the first housing 110 can be integrally injection molded, further reducing assembly steps.

[0069] The fourth rotating component 189 is rotatably mounted on the third housing 181 and connected to the second housing 140. Rotation of the fourth rotating component 189 causes the second housing 140 to rotate. Optionally, the fourth rotating component 189 and the second housing 140 are detachably connected, for example, by screws. This allows for assembly where the fourth rotating component 189 is first assembled with the third housing 181, and then the third housing 181 is assembled with the first housing 110, reducing assembly difficulty. Alternatively, the fourth rotating component 189 and the second housing 140 can be integrally injection molded, further reducing assembly steps.

[0070] By providing the third rotating assembly 188 and the fourth rotating assembly 189, the first housing 110 and the second housing 140 can rotate around different axes, thereby separating the first housing 110 and the second housing 140 and preventing interference between them during rotation. This also makes the first housing 110 and the second housing 140 more stable during rotation.

[0071] like Figures 10-12 As shown, in some embodiments, the third rotating component 188 and the fourth rotating component 189 are connected in a transmission manner, meaning that the third rotating component 188 and the fourth rotating component 189 rotate simultaneously and remain stationary at the same time, and their rotation directions are opposite. When the third rotating component 188 rotates towards the fourth rotating component 189, the fourth rotating component 189 also rotates towards the third rotating component 188. Conversely, when the third rotating component 188 rotates away from the fourth rotating component 189, the fourth rotating component 189 also rotates away from the third rotating component 188. Since the third rotating component 188 and the fourth rotating component 189 are both located in the third housing 181, that is, the first housing 110 and the second housing 140 rotate relative to the third housing 181, and the angle of rotation of the first housing 110 relative to the third housing 181 is relatively small, and the angle of rotation of the second housing 140 relative to the third housing 181 is relatively small, it is beneficial to make the gap between the first housing 110 and the third housing 181 smaller, and the gap between the second housing 140 and the third housing 181 smaller, so as to minimize the falling of debris into the power bank 100.

[0072] like Figures 10-12As shown, in some embodiments, the third rotating assembly 188 includes a fourth rotating shaft 1881, a fifth gear 1882, and a fourth connecting member 1883. The fourth connecting member 1883 connects the fifth gear 1882 and the first housing 110, and the connection between the fourth connecting member 1883 and the first housing 110 can be a screw connection. The fourth rotating shaft 1881 is rotatably disposed on the third housing 181, and the fifth gear 1882 is fixedly connected to the fourth rotating shaft 1881; alternatively, the fourth rotating shaft 1881 is fixedly disposed on the third housing 181, and the fifth gear 1882 is rotatably disposed on the fourth rotating shaft 1881, requiring only that the fifth gear 1882 rotate relative to the third housing 181. The fifth gear 1882 and the fourth connecting member 1883 are connected to the third housing 181 through the fourth rotating shaft 1881, and the fifth gear 1882 and the fourth connecting member 1883 may not be in contact with the third housing 181.

[0073] The fourth rotating assembly 189 includes a fifth rotating shaft 1891, a sixth gear 1892, and a fifth connecting member 1893. The fifth connecting member 1893 connects the sixth gear 1892 and the second housing 140, and the connection between the fifth connecting member 1893 and the second housing 140 can be a screw connection. The fifth rotating shaft 1891 is rotatably mounted on the third housing 181, and the sixth gear 1892 is fixedly connected to the fifth rotating shaft 1891; alternatively, the fifth rotating shaft 1891 is fixedly mounted on the third housing 181, and the sixth gear 1892 is rotatably mounted on the fifth rotating shaft 1891, requiring only that the sixth gear 1892 rotates relative to the third housing 181. The fifth gear 1882 meshes with the sixth gear 1892, thereby realizing the transmission connection between the third rotating assembly 188 and the fourth rotating assembly 189, and the rotation directions of the third rotating assembly 188 and the fourth rotating assembly 189 are opposite. The sixth gear 1892 and the fifth connector 1893 are connected to the third housing 181 via the fifth rotating shaft 1891, and the sixth gear 1892 and the fifth connector 1893 can be kept out of contact with the third housing 181.

[0074] like Figures 13-15 As shown, in some embodiments, the first rotating component 182 is provided with a first mating portion 1824, and the mobile power supply 100 also includes a first limiting member 184. The first limiting member 184 and the first mating portion 1824 engage in a limiting fit to restrict the rotation of the first rotating component 182. The first limiting member 184 can be a first limiting protrusion provided on the side of the third gear 1822, and the first mating portion 1824 can be a first limiting groove provided on the first limiting member 184. The first limiting protrusion and the first limiting groove engage in a limiting fit, thereby keeping the first housing 110 and the third housing 181 relatively stationary. Optionally, there can be multiple first limiting protrusions and first limiting grooves, with multiple first limiting protrusions corresponding one-to-one with multiple first limiting grooves, thereby achieving a better limiting effect.

[0075] like Figures 13-15 As shown, in some embodiments, the second rotating assembly 183 is provided with a second mating portion 1834, and the mobile power supply 100 also includes a second limiting member 185. The second limiting member 185 and the second mating portion 1834 are mutually limitingly engaged to restrict the rotation of the second rotating assembly 183. The second limiting member 185 can be a second limiting protrusion provided on the side of the fourth gear 1832, and the first mating portion 1824 can be a second limiting groove provided on the second limiting member 185. The second limiting protrusion and the second limiting groove are mutually limitingly engaged, thereby keeping the second housing 140 and the third housing 181 relatively stationary. Optionally, there can be multiple first limiting protrusions and first limiting grooves, with multiple first limiting protrusions corresponding one-to-one with multiple first limiting grooves, thereby achieving a better limiting effect.

[0076] For example, the first limiting member 184 is sleeved on the second rotating shaft 1821, the second limiting member 185 is sleeved on the third rotating shaft 1831, and the power bank 100 also includes a first elastic member 186 and a second elastic member 187. The two ends of the first elastic member 186 abut against the first limiting member 184 and the third housing 181 respectively, and the first elastic member 186 presses the first limiting member 184 against the first gear. The two ends of the second elastic member 187 abut against the second limiting member 185 and the third housing 181 respectively, and the second elastic member 187 presses the second limiting member 185 against the second gear.

[0077] Optionally, when the first housing 110 and the third housing 181 remain relatively stationary, and the second housing 140 and the third housing 181 remain relatively stationary, the first housing 110 and the second housing 140 can remain relatively stationary. For example, the power bank 100 can be limited in the first state and the second state.

[0078] Optionally, the first limiting member 184 and the second limiting member 185 can be integrally formed, thereby reducing the number of parts in the power bank 100.

[0079] like Figure 16 As shown, in some embodiments, the second rotating structure 180 includes a sixth rotating shaft 1894.

[0080] The sixth rotating shaft 1894 is rotatably disposed on the first housing 110, and the sixth rotating shaft 1894 is fixedly connected to the second housing 140.

[0081] Alternatively, the sixth rotating shaft 1894 is rotatably disposed on the second housing 140, and the sixth rotating shaft 1894 is fixedly connected to the first housing 110.

[0082] Alternatively, the sixth rotating shaft 1894 is rotatably disposed on the first housing 110, and the sixth rotating shaft 1894 is rotatably disposed on the second housing 140.

[0083] That is, the second rotating structure 180 is a single-axis setting, which makes the structure of the second rotating structure 180 relatively simple, the production cost low, and the space occupied small, which is conducive to the miniaturization of the power bank 100.

[0084] In some embodiments, the power bank 100 further includes a first driving member, which is tractively connected to a first rotating structure 170 to drive the connection terminal 150 to rotate relative to the second housing 140. The first driving member may be a first motor, thereby driving the connection terminal 150 to automatically fold or unfold.

[0085] In some embodiments, the first driving member is simultaneously connected to the first rotating structure 170 and the second rotating structure 180 to drive the connecting terminal 150 to rotate relative to the second housing 140, and to drive the first housing 110 to rotate relative to the second housing 140.

[0086] In some embodiments, the power bank 100 further includes a second driving member, which is tractively connected to the second rotating structure 180 to drive the first housing 110 to rotate relative to the second housing 140. The second driving member may be a second motor, thereby driving the power bank 100 to automatically fold or unfold.

[0087] When the power bank 100 is equipped with a linkage structure 190, the power bank 100 only needs to be equipped with one of the first driving member and the second driving member to drive the connection terminal 150 to rotate relative to the second housing 140, and at the same time drive the first housing 110 to rotate relative to the second housing 140.

[0088] In some embodiments, the power bank 100 may be provided with a first driving member and a second driving member, wherein the first driving member is connected to the first rotating structure 170 and the second driving member is connected to the second rotating structure 170, so that the power bank 100 can be automatically folded or unfolded by the first driving member and the second driving member.

Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
