Description

Power bank

[0001] This application claims priority to Chinese Patent Application No. 2025100479705, entitled "Power Bank", filed on January 10, 2025, and Chinese Patent Application No. 2025200688369, entitled "Power Bank", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of mobile power bank technology, and more particularly to a mobile power bank. Background Technology

[0003] 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. Summary of the Invention

[0004] This application provides a portable power bank that can enhance the support for mobile phones and improve the stability of mobile phones during charging.

[0005] This application provides 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 rotating component, and a rotating assembly. 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 the electrical connection assembly is electrically connected to the connecting terminal and the circuit board. The rotating component connects the connecting terminal to the second housing, allowing the connecting terminal to rotate relative to the second housing. The rotating assembly includes: a first rotating shaft connected to the first housing; a second rotating shaft connected to the second housing; a third rotating shaft, wherein the axes of the first, second, and third rotating shafts are parallel to each other and spaced apart, forming a triangular arrangement, and the third rotating shaft is disposed between the first and second rotating shafts; a first connecting member having a first connecting arm, with the first and third rotating shafts rotatably connected to both sides of the first connecting arm; and a second connecting member having a second connecting arm, with the second and third rotating shafts rotatably connected to both sides of the second connecting arm.

[0006] The power bank of this application has a first housing that can rotate relative to the second housing, and a connection terminal that can rotate relative to the second housing. When charging is required, the first housing can be rotated to form an angle with the second housing, and the connection terminal can be rotated to be approximately parallel to the first housing. When the electronic device is plugged into the connection terminal, the first housing can abut against the front or back of the electronic device, thereby providing support for the electronic device and making the electronic device more stable during charging.

Embodiments of the present invention

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] As shown in Figures 1-4, the first aspect of this application provides a mobile power supply 100, which includes 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 rotating component 170, and a rotating assembly 180.

[0034] Battery 120 is configured to store electrical energy, which can then be released when needed. The type of battery 120 is, for example, a steel-cased battery 120 or a pouch battery 120. The shape of battery 120 is, for example, cylindrical, square, etc., and the capacity of battery 120 is, for example, any value between 2000mAh and 30000mAh. Circuit board 130 is electrically connected to battery 120 and is configured to control the charging and discharging of battery 120. For example, the battery 120 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.

[0035] 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.

[0036] The connection terminal 150 is configured to plug into an electronic device to supply power to the device. Examples of electronic devices include mobile phones, wireless headphones, and tablets. Examples of connection terminal types include USB Type-C, Lightning, and Micro USB. The connection terminal 150 is disposed within a second housing 140, which is configured to mount and protect the connection terminal 150. The second housing 140 is, for example, made of plastic, allowing for the manufacture of complex shapes at a relatively low cost while providing insulation. Alternatively, the second housing 140 may be made of metal, providing high strength and a longer service life. The second housing 140 may also be plate-shaped, resulting in a relatively thin profile.

[0037] Electrical connection assembly 160 electrically connects connection terminal 150 and circuit board 130, so that 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.

[0038] The rotating member 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 degree of 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. Optionally, the second housing 140 is provided with a groove, and the connection terminal 150 can be stored in the groove or protrude from the groove, so that the outer surface of the second housing 140 is relatively flat and has an integrated design, which further improves the portability of the power bank 100 and further reduces the probability of the connection terminal 150 being scratched by external objects. The connection terminal 150 is at least partially hidden in the second housing 140, which improves the safety of use.

[0039] The rotating assembly 180 connects the first housing 110 and the second housing 140, allowing the first housing 110 to rotate relative to the second housing 140. 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 improving stability during charging. Furthermore, since the first housing 110 can abut against the front or back of the electronic device, it can be stacked with the electronic device, resulting in a smaller overall assembly size when the electronic device and the power bank 100 are charging, occupying a relatively neat space and making it easy to carry. When charging is not required, the first housing 110 can be rotated to be parallel to the second housing 140, resulting in a neat, integrated design for the power bank 100, making it easy to carry and less prone to scratches from other external objects.

[0040] As shown in Figures 1-4, in some embodiments, the power bank 100 has a first state and a second state. As shown in Figures 1-2, the power bank 100 is in the first state. As shown in Figures 3-4, the power bank 100 is in the second state. When 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 can rotate or remain stationary relative to the second housing. That is, the angle between the connecting terminal and the second housing can change or remain unchanged. In other words, when the power bank 100 is in the second state, the angle between the connecting terminal and the second housing can be 0 degrees or 90 degrees, or any angle in between.

[0041] Optionally, as shown in Figures 1-2, 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. As shown in Figures 3-4, the power bank 100 is in a 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 mobile phones and other electronic devices is located at the bottom of the phone, 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 mobile phone or other electronic device, which helps the first housing 110 support the mobile phone or other electronic device.

[0042] 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 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.

[0043] As shown in Figures 2 and 4, 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 tail end of the connection terminal 150 can rotate, and the tail end of the connection terminal 150 is positioned away from the first housing 110. This allows the rotating member 170 to be arranged away from the first housing 110, thereby reducing the difficulty of arrangement.

[0044] Optionally, the head of the connecting terminal 150 can be positioned as close as possible to the first housing 110. Given a fixed length of the connecting terminal 150, this reduces the distance between the connecting terminal 150 and the first housing 110 when the power bank 100 is in its second state. For example, the first housing 110 is provided with a clearance groove for accommodating the connecting terminal 150, allowing the connecting terminal 150 to utilize the space of the first housing 110, further reducing the distance H between the connecting terminal 150 and the first housing 110 when the power bank 100 is in its second state.

[0045] In some embodiments, the second housing 140 can move relative to the first housing 110 when rotating. For example, when the mobile power supply 100 rotates from the first state to the second state, the distance between the rotation axis of the second housing 140 and the rotation axis of the first housing 110 increases, thereby avoiding collision interference between the first housing 110 and the second housing 140, and making the rotation between the first housing 110 and the second housing 140 smoother.

[0046] When the power bank 100 rotates from the second state to the first state, the distance between the rotation axis of the second housing 140 and the rotation axis of the first housing 110 decreases. This results in a smaller gap between the first housing 110 and the second housing 140 in the first state, minimizing the possibility of foreign objects entering the first housing 110 or the second housing 140. The specific movement of the rotation axis of the second housing 140 relative to the rotation axis of the first housing 110 will be explained later.

[0047] As shown in Figure 5, in some embodiments, the power bank 100 further includes a linkage structure 190, which is connected to the rotating member 170 and the rotating assembly 180. The rotating assembly 180 can drive the rotating member 170 to rotate through the linkage structure 190, so that the rotating member 170 and the rotating assembly 180 rotate simultaneously. By setting the linkage structure 190, when the first housing 110 and the second housing 140 rotate relative to each other, the connecting terminal 150 can rotate relative to the second housing 140 simultaneously. The user does not need to rotate the first housing 110 or the second housing 140 and the connecting terminal 150 separately, saving operation steps and making the power bank 100 more convenient to use.

[0048] As shown in Figure 5, in some embodiments, the linkage structure 190 includes a crank 191 and a connecting rod 192. The crank 191 is connected to the rotating component 170, and the connecting rod 192 is rotatably connected to the rotating assembly 180 and the crank 191. The crank 191 and the connecting rod 192 constitute a crank 191-connecting rod 192 mechanism. The crank 191-connecting rod 192 mechanism can convert reciprocating linear motion into rotational motion, and has fewer parts, occupying relatively little space. Optionally, the rotating assembly 180 can provide linear motion to the connecting rod 192.

[0049] Optionally, when the power bank 100 rotates from the first state to the second state, the angle between the crank 191 and the connecting rod 192 increases, which facilitates the unfolding of the connection terminal 150. When the power bank 100 rotates from the second state to the first state, the angle between the crank 191 and the connecting rod 192 decreases, which facilitates the retraction of the connection terminal 150.

[0050] As shown in Figure 5, in some embodiments, the rotating member 170 is rotatably disposed on the second housing 140, the connecting terminal 150 is connected to the rotating member 170, and the linkage structure 190 is connected to the rotating member 170 and can drive the rotating member 170 to rotate. The rotating member 170 can be, for example, a shaft, a gear, a pulley, etc. When the rotating member 170 is a shaft, the linkage structure 190 includes a crank 191 and a connecting rod 192, with the crank 191 connected to the shaft. When the rotating member 170 is a gear, the linkage structure 190 can also be a gear. When the rotating member 170 is a pulley, the linkage structure 190 can be a transmission belt. It should be noted that the connecting terminal 150 can be fixedly disposed with the rotating member 170, in which case the rotating member 170 is rotatably disposed on the second housing 140. Alternatively, the connecting terminal 150 can be rotatably connected to the rotating member 170. In this case, the rotating member 170 can be fixedly disposed on the second housing 140 or rotatably disposed on the second housing 140. The crank 191 can be disposed on the connecting terminal 150, and the connecting rod 192 drives the crank 191 and the connecting terminal 150 to rotate.

[0051] As shown in Figure 6, in some embodiments, a receiving groove 140a is provided on the wall surface of the second housing 140, and the rotating member 170 is at least partially accommodated in the receiving groove 140a. This allows the rotating member 170 to be accommodated using the wall thickness of the second housing 140, thereby reducing the size of the second housing 140. Optionally, the groove wall of the receiving groove 140a is spaced apart from the rotating member 170, i.e., a gap is provided between the rotating member 170 and the groove wall of the receiving groove 140a, thereby preventing friction between the rotating member 170 and the groove wall of the receiving groove 140a. Optionally, the gap between the groove wall of the receiving groove 140a and the rotating member 170 is small, for example, 0.5 mm, thereby making the assembly more compact and minimizing the possibility of debris entering the receiving groove 140a through the gap.

[0052] As shown in Figure 7, in some embodiments, the rotating assembly 180 includes a first rotating shaft 1811, a second rotating shaft 1812, a third rotating shaft 1813, a first connecting member 1821, and a second connecting member 1822. The axes of the first rotating shaft 1811, the second rotating shaft 1812, and the third rotating shaft 1813 are parallel to each other and not collinear, that is, the first rotating shaft 1811, the second rotating shaft 1812, and the third rotating shaft 1813 are arranged in a triangle, and the third rotating shaft 1813 is located between the first rotating shaft 1811 and the second rotating shaft 1812.

[0053] The first rotating shaft 1811 is connected to the first housing 110. The first rotating shaft 1811 can be directly connected to the first housing 110 or indirectly connected to the first housing 110. The rotation axis of the first housing 110 is the axis of the first rotating shaft 1811.

[0054] The second rotating shaft 1812 is connected to the second housing 140. The second rotating shaft 1812 can be directly connected to the second housing 140 or indirectly connected to the second housing 140. The rotation axis of the second housing 140 is the axis of the second rotating shaft 1812.

[0055] It should be noted that the first rotating shaft 1811 can be rotatably mounted on the first housing 110 or fixedly mounted on the first housing 110. When the first rotating shaft 1811 is rotatably mounted on the first housing 110, the first connecting member 1821 can be fixedly connected to or rotatably connected to the first rotating shaft 1811. When the first rotating shaft 1811 is fixedly mounted on the first housing 110, the first connecting member 1821 is rotatably connected to the first rotating shaft 1811. The second rotating shaft 1812 can be rotatably mounted on the second housing 140 or fixedly mounted on the second housing 140. When the second rotating shaft 1812 is rotatably mounted on the second housing 140, the second connecting member 1822 can be fixedly connected to or rotatably connected to the second rotating shaft 1812. When the second rotating shaft 1812 is fixedly mounted on the second housing 140, the second connecting member 1822 is rotatably connected to the second rotating shaft 1812.

[0056] The third rotating shaft 1813 is spaced apart from the first rotating shaft 1811 and the second rotating shaft 1812, and the axes of the first rotating shaft 1811, the second rotating shaft 1812 and the third rotating shaft 1813 are all parallel.

[0057] The first connector 1821 has a first connecting arm 1823, and a first rotating shaft 1811 and a third rotating shaft 1813 are respectively rotatably connected to the two ends of the first connecting arm 1823, that is, the distance between the first rotating shaft 1811 and the third rotating shaft 1813 remains unchanged.

[0058] The second connector 1822 has a second connecting arm 1824, with a second rotating shaft 1812 and a third rotating shaft 1813 rotatably connected to both ends of the second connecting arm 1824, meaning the distance between the second rotating shaft 1812 and the third rotating shaft 1813 remains constant. For example, the second connecting arm 1824 has a third end and a fourth end, with a first rotating shaft 1811 and a third rotating shaft 1813 rotatably connected to the third end and the fourth end, respectively.

[0059] Since the first housing 110 can rotate around the first axis 1811 and also around the third axis 1813, and the second housing 140 can rotate around the second axis 1812 and also around the third axis 1813, there are three rotational degrees of freedom between the first housing 110 and the second housing 140, thus achieving different rotation modes.

[0060] As shown in Figure 7, in some embodiments, the first connector 1821 further has a third connector 1825 connected to the first connector 1823, and the first connector 1823 and the third connector 1825 are arranged at an angle. The angle between the first connector 1823 and the third connector 1825 can be, for example, an acute angle, an obtuse angle, or a right angle.

[0061] The second connector 1822 also has a fourth connector 1826 connected to the second connector 1824, the second connector 1824 and the fourth connector 1826 being arranged at an angle. The angle between the second connector 1824 and the fourth connector 1826 can be, for example, an acute angle, an obtuse angle or a right angle.

[0062] Optionally, the third rotating shaft 1813 is disposed at the connection position between the first connecting arm 1823 and the third connecting arm 1825. Optionally, the third rotating shaft 1813 is disposed at the connection position between the second connecting arm 1824 and the fourth connecting arm 1826.

[0063] The third connecting arm 1825 is connected to the second housing 140, and the third connecting arm 1825 may be directly connected to the second housing 140 or indirectly connected to the second housing 140. The fourth connecting arm 1826 is connected to the first housing 110, and the fourth connecting arm 1826 may be directly connected to the first housing 110 or indirectly connected to the first housing 110.

[0064] The first connector 1821 and the second connector 1822 can be spaced apart or abut against each other in the axial direction of the third rotating shaft 1813.

[0065] Optionally, the first connecting member 1821 is located at the middle position of the third rotating shaft 1813, thereby ensuring uniform force distribution at both ends of the third rotating shaft 1813. Optionally, the first connecting member 1821 is located at the middle position of the first rotating shaft 1811, thereby ensuring uniform force distribution at both ends of the first rotating shaft 1811. Optionally, the second connecting member 1822 is located at the middle position of the third rotating shaft 1813, thereby ensuring relatively uniform force distribution at both ends of the third rotating shaft 1813. Optionally, the second connecting member 1822 is located at the middle position of the second rotating shaft 1812, thereby ensuring relatively uniform force distribution at both ends of the second rotating shaft 1812. The first connecting member 1821 can be a sheet-like structure, thereby making the thickness of the first connecting member 1821 relatively thin and reducing the space occupied by the first connecting member 1821. The second connecting member 1822 can be a sheet-like structure, thereby making the thickness of the second connecting member 1822 relatively thin and reducing the space occupied by the second connecting member 1822.

[0066] As shown in Figure 8, in some embodiments, the rotating assembly 180 further includes a third housing 183 and a fourth housing 184. A first rotating shaft 1811 is disposed on the third housing 183, and the third housing 183 is detachably connected to the first housing 110. Exemplarily, the third housing 183 and the first housing 110 are fixed with screws. A second rotating shaft 1812 is disposed on the fourth housing 184, and the fourth housing 184 is detachably connected to the second housing 140. Exemplarily, the fourth housing 184 and the second housing 140 are fixed with screws.

[0067] With this configuration, the first housing 110, the second housing 140, and the rotating assembly 180 can be manufactured separately and then assembled, thereby reducing production difficulty. Moreover, if any one of the first housing 110, the second housing 140, or the rotating assembly 180 is damaged, it can be replaced individually, thereby reducing maintenance costs.

[0068] In some other embodiments, the third housing 183 and the first housing 110 can be integrally formed, and the fourth housing 184 and the second housing 140 can be integrally formed, thereby reducing the number of parts in the power bank 100 and reducing assembly steps.

[0069] Figures 8 and 9 are schematic diagrams of the rotating component 180 when the power bank 100 is in the second state, and Figure 10 is a schematic diagram of the rotating component 180 when the power bank 100 is in the first state. The following describes the process of the power bank 100 switching between the first state and the second state, taking the example of the first rotating shaft 1811 being fixed to the first housing 110 and the second rotating shaft 1812 being fixed to the second housing 140.

[0070] As shown in Figure 7, the first rotating shaft 1811 can rotate counterclockwise relative to the first connecting member 1821, that is, the third housing 183 rotates counterclockwise as shown in Figure 8. When the third housing 183 rotates counterclockwise, it will press down against the fourth connecting arm 1826, so that the second connecting member 1822 rotates counterclockwise relative to the third rotating shaft 1813. The second rotating shaft 1812 follows the second connecting member 1822 in rotating counterclockwise relative to the third rotating shaft 1813.

[0071] The second pivot 1812 can rotate clockwise relative to the second connector 1822, that is, the fourth housing 184 rotates clockwise. When the fourth housing 184 rotates clockwise, it will press down against the third connecting arm 1825, so that the first connector 1821 rotates clockwise relative to the third pivot 1813. The first pivot 1811 follows the second connector 1822 in rotating clockwise relative to the third pivot 1813.

[0072] Since the second rotating shaft 1812 rotates counterclockwise relative to the third rotating shaft 1813 and the first rotating shaft 1811 rotates clockwise relative to the third rotating shaft 1813, the second rotating shaft 1812 and the first rotating shaft 1811 move closer to each other, that is, the third housing 183 and the fourth housing 184 move closer to each other, that is, the first housing 110 and the second housing 140 move closer to each other, so that the first housing 110 and the second housing 140 can be combined more compactly, thereby reducing the gap between the first housing 110 and the second housing 140 and preventing foreign objects from entering the power bank 100.

[0073] Furthermore, since the third housing 183 rotates counterclockwise and the fourth housing 184 rotates clockwise, the third housing 183 and the fourth housing 184 can be rotated from being set at an angle to being set in parallel, that is, the third housing 183 and the fourth housing 184 can be rotated from the state shown in Figure 8 to the state shown in Figure 5.

[0074] Similarly, as shown in Figure 10, the first rotating shaft 1811 can rotate clockwise relative to the first connecting member 1821, that is, the third housing 183 rotates clockwise. When the third housing 183 rotates clockwise, it will press upward against the fourth connecting arm 1826, so that the second connecting member 1822 rotates clockwise relative to the third rotating shaft 1813. The second rotating shaft 1812 follows the second connecting member 1822 in rotating clockwise relative to the third rotating shaft 1813.

[0075] The second rotating shaft 1812 can rotate counterclockwise relative to the second connecting member 1822, that is, the fourth housing 184 rotates counterclockwise. When the fourth housing 184 rotates counterclockwise, it will press upward against the third connecting arm 1825, so that the first connecting member 1821 rotates counterclockwise relative to the third rotating shaft 1813. The first rotating shaft 1811 follows the second connecting member 1822 in rotating counterclockwise relative to the third rotating shaft 1813.

[0076] Since the second rotating shaft 1812 rotates clockwise relative to the third rotating shaft 1813 and the first rotating shaft 1811 rotates counterclockwise relative to the third rotating shaft 1813, the second rotating shaft 1812 and the first rotating shaft 1811 move away from each other, that is, the third housing 183 and the fourth housing 184 move away from each other, that is, the first housing 110 and the second housing 140 move away from each other, thereby avoiding interference and collision between the first housing 110 and the second housing 140 during rotation.

[0077] Furthermore, since the third housing 183 rotates clockwise and the fourth housing 184 rotates counterclockwise, the third housing 183 and the fourth housing 184 can be rotated from being arranged in parallel to being arranged at an angle, that is, the third housing 183 and the fourth housing 184 can be rotated from the state shown in Figure 5 to the state shown in Figure 8.

[0078] The second rotating shaft 1812 is close to the first rotating shaft 1811, that is, the rotation axis of the first housing 110 is close to the rotation axis of the second housing 140; the second rotating shaft 1812 is far from the first rotating shaft 1811, that is, the rotation axis of the first housing 110 is far from the rotation axis of the second housing 140.

[0079] It should be noted that the first rotating shaft 1811 can rotate counterclockwise relative to the first connecting member 1821, which in turn causes the second rotating shaft 1812 to rotate counterclockwise relative to the third rotating shaft 1813. In this case, the second rotating shaft 1812 and the first connecting member 1821 will move relative to each other, and the first connecting member 1821 will then drive the first rotating shaft 1811 to rotate clockwise relative to the third rotating shaft 1813, thereby achieving linkage between the first housing 110 and the second housing 140. Similarly, the second rotating shaft 1812 can rotate clockwise relative to the second connecting member 1822, which in turn causes the first rotating shaft 1811 to rotate clockwise relative to the third rotating shaft 1813. In this case, the first rotating shaft 1811 and the second connecting member 1822 will move relative to each other, and the second connecting member 1822 will then drive the second rotating shaft 1812 to rotate clockwise relative to the third rotating shaft 1813, thereby achieving linkage between the first housing 110 and the second housing 140.

[0080] As shown in Figure 11, in some embodiments, the number of first connectors 1821 is at least two, wherein the two first connectors 1821 are abutted or spaced apart. By setting at least two first connectors 1821, the constraint ability on the first rotating shaft 1811 and the third rotating shaft 1813 can be enhanced, and the stability of the first housing 110 when rotating can be improved.

[0081] Optionally, the two first connecting members 1821 are spaced apart axially on the third rotating shaft 1813, so that the force on the first rotating shaft 1811 and the third rotating shaft 1813 is more uniform.

[0082] As shown in Figure 11, in some embodiments, there are at least two second connectors 1822, wherein the two second connectors 1822 are abutted or spaced apart. By providing at least two second connectors 1822, the constraint on the second rotating shaft 1812 and the third rotating shaft 1813 can be enhanced, and the stability of the second housing 140 when rotating can be improved.

[0083] Optionally, the two second connecting members 1822 are spaced apart axially on the third rotating shaft 1813, so that the force on the first rotating shaft 1811 and the third rotating shaft 1813 is more even.

[0084] As shown in Figure 11, in some embodiments, there are at least two first connectors 1821 and at least two second connectors 1822. One of the first connectors 1821 and one of the second connectors 1822 are located at one end of the third rotating shaft 1813, and the other first connector 1821 and the other second connector 1822 are located at the other end of the third rotating shaft 1813, so that the force on both ends of the third rotating shaft 1813 is more uniform.

[0085] As shown in Figure 12, in some embodiments, the number of first connectors 1821 is at least three. These three first connectors 1821 abut sequentially along the axial direction of the third rotating shaft 1813; or two first connectors 1821 abut against each other along the axial direction of the third rotating shaft 1813, and each is spaced apart from another first connector 1821 along the axial direction of the third rotating shaft 1813; or all three first connectors 1821 are spaced apart from each other along the axial direction of the third rotating shaft 1813. By providing at least three first connectors 1821, the constraint capability on the first rotating shaft 1811 and the third rotating shaft 1813 can be further enhanced, improving the stability of the second housing 140 during rotation.

[0086] As shown in Figure 12, in some embodiments, the number of second connectors 1822 is at least three. These three second connectors 1822 abut sequentially along the axial direction of the third rotating shaft 1813; or two second connectors 1822 abut against each other along the axial direction of the third rotating shaft 1813, and each is spaced apart from another second connector 1822 along the axial direction of the third rotating shaft 1813; or all three second connectors 1822 are spaced apart from each other along the axial direction of the third rotating shaft 1813. By providing at least three second connectors 1822, the constraint capability on the first rotating shaft 1811 and the third rotating shaft 1813 can be further enhanced, improving the stability of the second housing 140 during rotation.

[0087] Optionally, one of the first connectors 1821 is sandwiched between two of the second connectors 1822, and another second connector 1822 is sandwiched between two other first connectors 1821, so that the arrangement of the first connectors 1821 and the second connectors 1822 is more compact and less prone to shaking. Furthermore, friction can be generated between the first connector 1821 and the adjacent second connector 1822, which can provide damping for the rotating assembly 180, allowing the rotating assembly 180 to be suspended at any time during the process of rotating from the first state to the second state.

[0088] In some embodiments, the number of first connectors 1821 is four, five or more, and the number of second connectors 1822 is four, five or more, without limitation.

[0089] As shown in Figures 13-15, in some embodiments, the rotating assembly 180 further includes a fourth rotating shaft 1814. A first sliding groove 184a is provided on the fourth housing 184, and the fourth rotating shaft 1814 is slidably disposed in the first sliding groove 184a. Multiple first connecting members 1821 are rotatably connected to the fourth rotating shaft 1814. The fourth rotating shaft 1814 can cause the multiple first connecting members 1821 to rotate synchronously, thereby making the rotating assembly 180 more stable during rotation. By providing the first sliding groove 184a, the movement trajectory of the fourth rotating shaft 1814 can be limited, thereby limiting the rotation angle of the second housing 140. Optionally, the fourth rotating shaft 1814 is rotatably connected to the third connecting arm 1825, and the fourth rotating shaft 1814 is slidably disposed relative to the second housing 140, that is, the third connecting arm 1825 is connected to the second housing 140 through the fourth rotating shaft 1814. For example, the third connecting arm 1825 has a first end and a second end. The first end of the third connecting arm 1825 is connected to the first connecting arm 1823, and the second end of the third connecting arm 1825 is rotatably connected to the fourth rotating shaft 1814, that is, the fourth rotating shaft 1814 and the third rotating shaft 1813 are spaced apart.

[0090] In the above text, when the fourth housing 184 rotates clockwise, it will press down against the third connecting arm 1825, and when the fourth housing 184 rotates counterclockwise, it will press up against the third connecting arm 1825. It can be understood that the fourth housing 184 presses against the fourth rotating shaft 1814 through the groove wall of the first sliding groove 184a, which is equivalent to indirectly pressing against the third connecting arm 1825.

[0091] As shown in Figures 13-15, in some embodiments, the rotating assembly 180 further includes a fifth rotating shaft 1815. A second sliding groove 183a is provided on the third housing 183, and the fifth rotating shaft 1815 is slidably disposed in the second sliding groove 183a. Multiple second connecting members 1822 are rotatably connected to the fifth rotating shaft 1815. The fifth rotating shaft 1815 allows the multiple second connecting members 1822 to rotate synchronously, thereby making the rotating assembly 180 more stable during rotation. By providing the second sliding groove 183a, the movement trajectory of the fifth rotating shaft 1815 can be limited, thereby limiting the rotation angle of the first housing 110. Optionally, the fifth rotating shaft 1815 is rotatably connected to the fourth connecting arm 1826, and the fifth rotating shaft 1815 is slidably disposed relative to the first housing 110; that is, the fourth connecting arm 1826 is connected to the first housing 110 through the fifth rotating shaft 1815. For example, the fourth connecting arm 1824 has a third end and a fourth end. The third end of the fourth connecting arm 1824 is connected to the second connecting arm 1822, and the fourth end of the fourth connecting arm 1824 is rotatably connected to the fifth rotating shaft 1815. That is, the fifth rotating shaft 1815 is spaced apart from the third rotating shaft 1813.

[0092] In the above text, when the third housing 183 rotates counterclockwise, it will press down against the fourth connecting arm 1826, and when the third housing 183 rotates clockwise, it will press up against the fourth connecting arm 1826. It can be understood that the third housing 183 presses against the fifth rotating shaft 1815 through the groove wall of the second sliding groove 183a, which is equivalent to indirectly pressing against the fourth connecting arm 1826.

[0093] Optionally, by providing the first slide groove 184a and the second slide groove 183a, the second housing 140 and the first housing 110 can rotate relative to each other along a predetermined trajectory, allowing the power supply 100 to easily switch between a first state and a second state. The rotation angle of the connecting terminal 150 can be controlled by controlling the dimension of the first slide groove 184a in its sliding direction, or by controlling the dimension of the second slide groove 183a in its sliding direction.

[0094] In some embodiments, the first slide 184a has a groove opening and a groove bottom. When the fourth rotating shaft 1814 slides from the groove opening of the first slide 184a to the groove bottom of the first slide 184a, the angle between the connecting terminal 150 and the second housing 140 changes from 0 degrees to 90 degrees.

[0095] In some embodiments, the second slide 183a has a groove opening and a groove bottom. When the fifth rotating shaft 1815 slides from the groove opening of the second slide 183a to the groove bottom of the second slide 183a, the angle between the connecting terminal 150 and the second housing 140 changes from 0 degrees to 90 degrees.

[0096] As shown in Figures 16 and 17, the linear motion of the fourth rotating shaft 1814 can also provide power to the linkage structure 190. For example, the connecting rod 192 is hinged to the fourth rotating shaft 1814, the fourth rotating shaft 1814 drives the connecting rod 192 to swing, and the connecting rod 192 drives the rotating component 170 to rotate.

[0097] Alternatively, the linear motion of the fifth pivot 1815 can also provide power to the linkage structure 190. For example, the connecting rod 192 is hinged to the fifth pivot 1815, the fifth pivot 1815 drives the connecting rod 192 to swing, and the connecting rod 192 drives the rotating member 170 to rotate.

[0098] That is, the crank 191 and connecting rod 192 mechanism can convert the reciprocating linear motion of the fourth shaft 1814 or the fifth shaft 1815 into the rotational motion of the rotating member 170.

[0099] Optionally, the fourth shaft 1814 includes two sub-shafts spaced apart along the axial direction, that is, the middle part of the fourth shaft 1814 is disconnected to avoid the connection terminal 150.

[0100] As shown in Figures 18 and 19, in some embodiments, the power bank 100 further includes a fifth housing 185, on which a first sliding part 1851 and a second sliding part 1852 are provided, a third sliding groove 110a is provided on the first housing 110, and a fourth sliding groove 140b is provided on the second housing 140.

[0101] The first sliding part 1851 is disposed in the third slide groove 110a, and the first sliding part 1851 can rotate relative to the third slide groove 110a. The third slide groove 110a can limit the first sliding part 1851 to prevent the first sliding part 1851 from dislodging from the third slide groove 110a. The fifth housing 185 can slide relative to the first housing 110 and can rotate relative to the first housing 110.

[0102] The second sliding portion 1852 is disposed in the fourth sliding groove 140b, and the second sliding portion 1852 is rotatable relative to the fourth sliding groove 140b. The fourth sliding groove 140b can limit the second sliding portion 1852 to prevent the second sliding portion 1852 from dislodging from the fourth sliding groove 140b. The fifth housing 185 is slidable relative to the second housing 140 and is rotatable relative to the second housing 140.

[0103] When the first housing 110 rotates relative to the second housing 140, the fifth housing 185 rotates and moves relative to the first housing 110, and also rotates and moves relative to the second housing 140. The fifth housing 185 can serve as a decorative element to seal the gap between the first housing 110 and the second housing 140 when the power supply 100 is in the second state, and when the power supply 100 is in the first state, the fifth housing 185 can be stored inside the first housing 110 and the second housing 140.

[0104] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. 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.
