Description

Technical Field

[0001] This application belongs to the field of mobile charging equipment technology, and in particular relates to a dual-purpose mobile power supply that can charge both smartphones and smart wearable devices at the same time. Background Technology

[0002] With the rapid development of electronic products, there are many types of mobile smart terminals, such as smartphones and smart wearable devices, all designed for business or personal communication, photography, and computing needs. These mobile smart terminals are all limited by battery capacity and require timely charging to maintain battery life.

[0003] Nowadays, people carry portable power banks with them when they go out to charge their mobile smart devices anytime, thus giving them faster battery life. Traditional power banks only have wireless charging features for smartphones, allowing smartphones to be placed or magnetically attached to the power bank for wireless charging. For smart wearable devices, a wired charging connection can only be established by attaching a charging cable to the power bank's port.

[0004] As a result, power banks that integrate wireless charging for both smartphones and smart wearable devices have been launched on the market. The structure of such dual-purpose power banks is generally that wireless charging modules are set on opposite ends of the power bank. Specifically, one end of the power bank is equipped with a wireless charging module for wireless charging smartphones, and the other end of the power bank is equipped with a wireless charging module for wireless charging smart wearable devices, thereby meeting the simultaneous charging needs of both.

[0005] However, in practical applications, when a user places both a smartphone and a smart wearable device on the two ends of a power bank at the same time, the strap of the smart wearable device will either be wrapped around the power bank or be in an unfolded state, which can easily block the smartphone screen on the other end of the power bank, preventing the user from operating the smartphone while charging and affecting actual use. Summary of the Invention

[0006] The purpose of this application is to provide a portable power bank to solve the technical problem that the layout of existing dual-purpose portable power banks is unreasonable, which affects the operation of smartphones while charging.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a portable power bank, comprising:

[0008] The main body includes a shell, a main control board, a battery, and a first wireless charging module for charging a smartphone. The charging connection terminal of the first wireless charging module is located on the front of the main body, and the main control board and the battery are housed inside the shell.

[0009] A support body is mounted on the back of the main body via a hinge connection mechanism. The support body is used to support the main body so that the main body can stand up when it is opened. The support body is provided with a second wireless charging module for charging smart wearable devices. Both the first wireless charging module and the second wireless charging module are provided with magnetic modules for magnetic connection with smartphones and smart wearable devices.

[0010] The main control board is electrically connected to the first wireless charging module and the battery inside the housing. The connecting cable between the main control board and the second wireless charging module extends to the support body through the hinge connection mechanism and is electrically connected to the second wireless charging module.

[0011] The advantages of the portable power bank provided in this application are as follows: Compared with the prior art, the portable power bank of this application has a first wireless charging module for wireless charging of smartphones on the front of the main body, and a support body on the back of the main body, on which a second wireless charging module for wireless charging of smart wearable devices is mounted. Both the first and second wireless charging modules are equipped with magnetic modules, allowing smartphones and smart wearable devices to be wirelessly charged simultaneously on the portable power bank. This helps to save on charging accessories such as charging cables, allowing users to wirelessly charge their smartphones and smart wearable devices without carrying charging cables when going out, effectively improving ease of use.

[0012] The support body is mounted on the main body via a hinged connection mechanism. When opened, it forms a stand, allowing the power bank to stand upright, enabling users to charge their smartphones simultaneously and significantly improving the user experience. The strap of the smart wearable device can be wrapped around the opened support body, preventing obstruction of the smartphone screen on the front of the main body. The strap can also be unfolded. Because the support body is angled at the back of the main body when open, the unfolded strap tilts downwards and rests against a flat surface (such as a table), effectively reducing interference with hand operation on the smartphone screen and further enhancing the user experience.

[0013] The structure on the back of the outer casing is improved, with a boss on the back for mounting the hinge connection mechanism and the support body. The boss has a receiving groove for accommodating the support body. The hinge connection mechanism is disposed on the boss and movably connected to the support body, allowing the support body to open on the back of the main body or be inserted into the receiving groove of the boss. This facilitates hiding the support body on the back of the power bank main body for easy storage.

[0014] In one embodiment, the boss is centrally located on the back of the housing so that the support can be positioned on the central axis of the main body, effectively improving the support balance of the main body and thus enhancing the support effect.

[0015] The hinge connection mechanism is improved by including a pair of hinges and a pivot that passes through the connecting portion of the pair of hinges. One end of the hinge has a sleeve for fitting onto both ends of the pivot, and this end of the hinge is integrally formed with the support body. The other end of the hinge has a rolled edge for fitting onto the pivot, and this other end of the hinge is fixed to the boss. The inner wall of the rolled edge is in close contact with the outer periphery of the pivot to generate a damping force. This allows the support body to rotate on the back of the main body via the hinge connection mechanism to adjust the support angle, thereby improving the usability of charging and operating the phone simultaneously.

[0016] The structure of the support body is improved by having a conduit for the connecting cable to pass through. The conduit communicates with the second wireless charging module on the support body. The connecting cable exits from the protrusion of the outer shell and extends into the conduit to electrically connect with the second wireless charging module. Thus, the conduit on the support body provides a fixed channel for the connecting cable, which facilitates the protection and concealed wiring structure of the cable, thereby improving the stability of the electrical connection between the connecting cable and the second wireless charging module.

[0017] In one embodiment, the boss is further provided with a fitting groove located within the receiving groove. The fitting groove is shaped to fit the conduit, and when the support body is housed in the receiving groove, the conduit is embedded in the fitting groove. This helps to reduce the entry of foreign objects into the area of ​​the hinge connection mechanism, effectively ensuring the smooth movement of the hinge connection mechanism, and thus improving the sealing performance of the support body when closed on the boss.

[0018] In one embodiment, the boss is further provided with a groove located within the receiving slot for embedding the second wireless charging module. The groove is shaped to fit the second wireless charging module and communicates with the insertion slot. Thus, when the support body is placed on the receiving slot of the boss, the second wireless charging module can be embedded in the groove. This improves the tightness of the support body when stored on the back of the main body and enhances the positioning effect by utilizing the shape fit between the second wireless charging module and the groove.

[0019] In one embodiment, the boss is further provided with an operating notch that mates with the extension end of the support body. The operating notch communicates with the receiving groove and is used for manual operation to pry the support body out of the receiving groove. Thus, a person can operate the extension end of the support body through the operating notch, thereby prying the support body out of the receiving groove of the boss and opening it smoothly, effectively improving the efficiency of opening the support body.

[0020] In one embodiment, the extended end of the support body is provided with an inclined surface, which is oriented toward the operating notch. This creates a gap at the end of the support body with the inclined surface, allowing a person's finger to be inserted entirely or partially. This facilitates the insertion of the finger between the support body and the boss, making it easier to remove the support body from the receiving groove of the boss, thus further improving operational efficiency.

[0021] The main body structure has been improved, with a wiring port, a power indicator light, and a button located on the same side of the outer casing. These components are electrically connected to the main control board. This allows the user to simultaneously observe the power indicator light while operating the button, providing timely information about the battery level. The wiring port can be used for wired charging of smartphones or smart wearable devices via a charging cable, or for charging the battery in a power bank. Attached Figure Description

[0042] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0043] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0044] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0046] In related technologies, there are structures where wireless charging modules are respectively arranged on two opposite end faces of a power bank. For example, a wireless charging module for a smartphone is arranged on the front of the power bank, and another wireless charging module for a smart wearable device is arranged on the back of the power bank. Although this type of power bank can wirelessly charge both devices simultaneously, in actual use, when a user places both a smartphone and a smart wearable device on the two end faces of the power bank at the same time, the strap of the smart wearable device either gets wrapped around the power bank or is in an unfolded state, which can easily obstruct the smartphone screen on the other end face of the power bank, preventing the user from operating the smartphone while charging. The unfolded strap can also easily interfere with the user's operation of the smartphone.

[0047] Therefore, this application provides a novel dual-purpose power bank that can wirelessly charge both smartphones and smart wearable devices simultaneously, saving users the need to carry charging cables and other accessories when traveling, and making it more convenient to use. A support structure is added to the power bank, allowing it to function as a stand simultaneously. Users no longer need to hold both the smartphone and the power bank in one hand while charging and operating the phone. Furthermore, the added support structure helps to fix the posture of the smart wearable device, reducing the obstruction of the phone screen and interference with operation caused by the strap on the smart wearable device. This effectively solves the problem of unreasonable layout in traditional dual-purpose power banks, which affects the simultaneous charging and operation of smartphones. A detailed description follows.

[0048] Please see Figure 1 The mobile power supply of this application embodiment includes at least a main body 1 and a support body 2 disposed on the main body 1.

[0049] Please refer to the following: Figure 1 and Figure 2 The main body 1 includes a shell 11, a main control board 12, a battery 13, and a first wireless charging module 3 for charging smartphones. The charging connection end of the first wireless charging module 3 is located on the front of the shell 11 of the main body 1, so that the smartphone can be placed on the front of the main body 1 of the power bank for wireless charging. Figure 3 and Figure 4 As shown.

[0050] The main control board 12 and the battery 13 are housed inside the housing 11, and the main control board 12, the battery 13 and the first wireless charging module 3 are electrically connected inside the housing 11.

[0051] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The support body 2 is mounted on the back of the outer shell 11 of the main body 1 via a hinge connection mechanism 4. The support body 2 is used to support the main body 1 so that it can stand upright when opened. In this embodiment, the support body 2 can preferably be a plate, which is beneficial for storage on the main body 1, reducing the space occupied and the overall size of the power bank. Thus, when the support body 2 on the back of the main body 1 is opened, the main body 1 can stand upright, thereby forming a support structure, which makes it convenient to place a smartphone on the front of the main body 1, allowing users to charge and operate the phone at the same time.

[0052] Please refer to the following: Figure 1 , Figure 2 and Figure 4 The support 2 is equipped with a second wireless charging module 5 for charging smart wearable devices. Both the first wireless charging module 3 and the second wireless charging module 5 are equipped with magnetic modules 6 for magnetic connection with smartphones and smart wearable devices. In this embodiment, as... Figure 7 As shown, both the first wireless charging module 3 and the second wireless charging module 5 include charging coils. The magnetic module 6 is preferably a magnetic ring composed of multiple magnetic bodies (such as magnets), which surrounds the outer periphery of the charging coil. This allows smartphones to be magnetically attached to the first wireless charging module 3 for wireless charging, and smart wearable devices to be magnetically attached to the second wireless charging module 5 for wireless charging. This saves on additional connecting accessories such as charging cables, eliminating the need for users to carry charging cables when out and about, making it more convenient.

[0053] Please refer to the following: Figure 5 and Figure 6The main control board 12 is electrically connected to the first wireless charging module 3 and the battery 13 inside the outer casing 11. The connecting cable 14 between the main control board 12 and the second wireless charging module 5 extends to the support body 2 through the hinge connection mechanism 4 and is electrically connected to the second wireless charging module 5. The connecting cable 14 via the hinge connection mechanism 4 can preferably be a flexible PCB or coaxial cable, which is beneficial for adapting to folding or rotating structures, avoiding repeated bending damage, and thus extending its service life.

[0054] Compared with the prior art, the portable power bank provided in this application embodiment has a first wireless charging module 3 for wireless charging of smartphones on the front of the main body 1, and a support body 2 on the back of the main body 1. The support body 2 has a second wireless charging module 5 for wireless charging of smart wearable devices. Both the first wireless charging module 3 and the second wireless charging module 5 are provided with magnetic modules 6, allowing smartphones and smart wearable devices to be wirelessly charged simultaneously on the portable power bank. This saves on charging accessories such as charging cables, allowing users to wirelessly charge their smartphones and smart wearable devices without carrying charging cables when going out, effectively improving ease of use.

[0055] The support body 2 is mounted on the main body 1 via a hinge connection mechanism 4. When the support body 2 is opened, it forms a bracket, allowing the power bank to stand upright, making it convenient for users to charge their smartphones while operating them, thus effectively improving the user experience.

[0056] like Figure 3 As shown, the strap of the smart wearable device can be wrapped around the open support 2 to avoid obstructing the smartphone screen on the front of the main body 1.

[0057] like Figure 4 As shown, the strap of the smart wearable device can also be unfolded. Compared with the above-mentioned related technologies, since the support body 2 is tilted on the back of the main body 1 to support the main body 1 after it is opened, the unfolded smart wearable device strap tilts downward and rests against the placement surface (such as a table), effectively reducing interference with the user's hand operation on the smartphone screen and improving the operating experience.

[0058] In addition, since the second wireless charging module 5 is mounted on the support body 2, the second wireless charging module 5 will be separated from the main body 1 when the support body 2 is opened. This helps to reduce the impact of the heat generated on the second wireless charging module 5 during charging on the main body 1, thereby effectively improving heat dissipation.

[0059] Regarding the structure on the back of the outer shell 11 of the main body 1, please refer to one embodiment of this application. Figure 7 , Figure 8 and Figure 9 The back of the housing 11 has a boss 7 for mounting the hinge connection mechanism 4 and the support body 2, and the boss 7 has a receiving groove 71.

[0060] The hinge connection mechanism 4 is provided on the boss 7 and is movably connected to the support body 2, so that the support body 2 can be opened or embedded in the receiving groove 71 of the boss 7.

[0061] In this embodiment, a boss 7 is provided on the back of the main body 1, and a receiving groove 71 is provided inside the boss 7. The hinge connection mechanism 4 and the support body 2 are both arranged in the receiving groove 71 of the boss 7. This facilitates the concealment of the support body 2 on the back of the power bank main body 1, making it convenient to store and improving storage efficiency.

[0062] Preferably, the boss 7 is centrally located on the back of the outer casing 11. Since both the hinge connection mechanism 4 and the support body 2 are located on the receiving groove 71 of the boss 7, the support body 2 is also centrally located on the back of the main body 1, allowing the support body 2 to support the main body 1 on the central axis of the main body 1, effectively improving the support balance of the main body 1, and thus improving the support effect.

[0063] Preferably, the outer periphery of the boss 7 and the back of the main body 1 are smoothly transitioned to avoid forming corners or jammed corners, which helps to improve the grip.

[0064] For the specific structure of the hinge connection mechanism 4, please refer to one embodiment of this application. Figure 7 and Figure 10 The hinge connection mechanism 4 includes a pair of hinges 41 and a pivot 42, the pivot 42 being used to pass through the interconnecting portion of the pair of hinges 41. One end of the hinge 41 has a sleeve 411 for fitting onto both ends of the pivot 42, and this end of the hinge is integrally formed with the support body 2; the other end of the hinge 41 has a rolled edge 412 for fitting onto the pivot 42, and this other end of the hinge is fixed to the boss 7. The inner wall of the rolled edge 412 is in close contact with the outer periphery of the pivot 42 to generate a damping force.

[0065] In this way, the support 2 can rotate on the back of the main body 1 via the hinge connection mechanism 4 to adjust the support angle, thereby improving the usability of using the phone while charging.

[0066] Preferably, such as Figure 10As shown, the rolled edges 412 on the pair of hinges 41 are preferably configured as cylindrical structures, so that the rolled edges 412 can completely surround the outer periphery of the pivot 42. This helps to increase the contact area between the inner wall of the rolled edges 412 and the outer periphery of the pivot 42, thereby increasing the damping force and effectively improving the fixing effect on the support body 2. This allows the support body 2 to be locked at any opening angle to support the main body 1, thereby improving the support stability of the main body 1.

[0067] For the structure on support 2, please refer to one embodiment of this application. Figure 7 , Figure 10 and Figure 11 The support body 2 has a conduit 21 for threading the connecting cable 14, and the conduit 21 is connected to the second wireless charging module 5 on the support body 2.

[0068] The connecting cable 14 passes through the protrusion 7 of the housing 11 and extends into the conduit 21 to connect with the second wireless charging module 5.

[0069] In this embodiment, as Figure 11 As shown, the support body 2 has the conduit 21 on the end face facing the back of the main body 1, so that the connecting cable 14 can be inserted into the conduit 21 after it extends from the boss 7 and connect to the charging coil of the second wireless charging module 5, which helps to shorten the cable travel.

[0070] Preferably, the connecting cable 14 is spaced apart from the pivot 42 in the hinge connection mechanism 4, so that there is an isolation gap between the connecting cable 14 and the pivot 42, and the support body 2 can easily damage the connecting cable 14 during the opening and closing process.

[0071] In this way, the conduit 21 on the support 2 provides a fixed channel for the connecting cable 14, which is beneficial for covering and protecting the connecting cable 14 and forming a hidden wiring structure, thereby improving the electrical connection stability between the connecting cable 14 and the second wireless charging module 5.

[0072] In one embodiment of this application, please refer to Figure 11 In this embodiment, the main body 1 of the power bank is further provided with a mounting groove 72 located in the receiving groove 71. The mounting groove 72 is shaped and positioned to match the conduit 21 on the support body 2. When the support body 2 is housed in the receiving groove 71, the conduit 21 is embedded in the mounting groove 72.

[0073] In this embodiment, the conduit 21 is preferably centrally located on the support body 2, and the insertion groove 72 on the boss 7 is matched with the position of the conduit 21 in the receiving groove 71, so that when the support body 2 is covered on the receiving groove 71, the conduit 21 on the support body 2 can be just embedded in the insertion groove 72.

[0074] Therefore, by providing a fitting groove 72 within the receiving groove 71 of the boss 7 to precisely engage with the conduit 21 on the support body 2, it is beneficial to reduce the entry of foreign objects into the area of ​​the hinge connection mechanism 4, effectively ensuring the smooth operation of the hinge connection mechanism 4, preventing jamming or affecting the support angle, extending service life, and thus improving the sealing performance of the support body 2 when closed on the boss 7. In addition, the shape matching between the fitting groove 72 and the conduit 21 provides physical positioning when the support body 2 is stored, ensuring accurate alignment with each opening and closing, allowing the support body 2 to be stored in place.

[0075] In one embodiment of this application, please refer to Figure 11 The boss 7 on the back of the main body 1 is also provided with a groove 73 located in the receiving slot 71 for embedding the second wireless charging module 5. The shape of the groove 73 matches the shape of the second wireless charging module 5, and the groove 73 is connected to the insertion slot 72.

[0076] In this embodiment, the second wireless charging module 5 is preferably circular to match the circular movement shape of most smart wearable devices on the market, such as smartwatches; correspondingly, the groove 73 in the receiving groove 71 on the boss 7 is preferably circular to match the circular structure of the second wireless charging module 5.

[0077] In other embodiments (not shown), the second wireless charging module 5 may also preferably be a rectangular structure to fit the shape of a smart wearable device; correspondingly, the groove 73 in the receiving groove 71 on the boss 7 may also preferably be a rectangular groove to fit the shape of the second wireless charging module 5.

[0078] In this way, when the support 2 is placed on the receiving groove 71 of the boss 7, the second wireless charging module 5 can be embedded in the groove 73. This not only improves the tightness of the support 2 being stored on the back of the main body 1, but also improves the positioning effect by utilizing the shape matching of the second wireless charging module 5 and the groove 73.

[0079] In practical applications, the main body 1 of the power bank has a protrusion 7 on its back, and a receiving groove 71 is formed on the protrusion 7 to create a wall-like structure on the back of the main body 1. When the support body 2 is housed in the receiving groove 71 of the protrusion 7, it is equivalent to having a wall surrounding the outer perimeter of the support body 2. Therefore, it is difficult to open the support body 2 directly by hand, and even auxiliary tools are needed to pry the support body 2 off the protrusion 7 to open it smoothly, which is very inconvenient.

[0080] Therefore, the structure of the protrusion 7 on the back of the power bank body 1 is improved. In one embodiment of this application, please refer to the following. Figure 8 and Figure 9The boss 7 is also provided with an operation notch 74 that matches the position of the extended end of the support 2. The operation notch 74 is connected to the receiving groove 71 of the boss 7 so as to allow a person to manually pry the support 2 out of the receiving groove 71.

[0081] In this way, a person can operate the extended end of the support body 2 through the operation notch 74, thereby prying the support body 2 out of the receiving groove 71 of the boss 7 and opening it smoothly, effectively improving the operation efficiency of opening the support body 2.

[0082] Preferably, please refer to the following: Figure 8 and Figure 9 The extended end of the support body 2 is also provided with an inclined surface 22, which is arranged in the direction of the operating notch 74.

[0083] In this way, a gap is formed at the end of the support body 2 with the inclined surface 22, which allows a person's finger to be inserted entirely or partially. This facilitates the insertion of the finger between the support body 2 and the boss 7, making it easier to remove the support body 2 from the receiving groove 71 of the boss 7, thereby further improving the efficiency of operation.

[0084] Regarding the structure on the main body 1 of the power bank, please refer to one embodiment of this application. Figure 7 , Figure 8 and Figure 9 On the same side of the outer casing 11 of the main body 1, there is a wiring port 15, a power indicator light 16, and a button 17. The wiring port 15, the power indicator light 16, and the button 17 are electrically connected to the main control board 12. When the user operates the button 17, they can simultaneously observe the power indicator light 16 and promptly know the power status.

[0085] The connection port 15 can preferably be a USB interface, a TYPE-C interface, etc., so as to connect to a smartphone or smart wearable device for wired charging via a charging cable, or connect to a power source to charge the battery 13 in the power bank and replenish its power.

[0086] In practical applications, such as Figure 3 and Figure 4 As shown, when the main body 1 is supported by the support body 2 and stands upright, the smartphone is placed on the front of the main body 1. At this time, the camera on the back of the smartphone is close to the top side of the casing 11 of the main body 1. This will interfere with the operation of the button 17 on the main body 1, and it is also not convenient to install a charging cable on the wiring port 15 on the end face of the casing 11.

[0087] Therefore, in the embodiments of this application, please refer to... Figure 8 and Figure 9As shown, the connection port 15, power indicator light 16, and button 17 can preferably be positioned on the side of the housing 11 facing the placement surface (such as a desktop). In this way, when the support 2 on the power bank is stored, and a smartphone is placed on the front of the main body 1, the camera on the back of the smartphone is located on the side of the housing 11 other than the connection port 15, power indicator light 16, and button 17. This effectively avoids interference with operating the button 17 or adding a charging cable to the connection port 15, thereby improving the user experience.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
