Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a power bank. Background Technology

[0002] With the development of technology, the application of various portable electrical devices is becoming increasingly widespread. When people take portable electrical devices out, they can charge them using power banks.

[0003] Currently, wireless charging technology is being used in power banks. However, when power banks with wireless charging capabilities are charging devices, the devices may easily deviate from the charging position or even slip off the power bank, causing instability in the charging process. Summary of the Invention

[0004] The main technical problem this application addresses is to provide a power bank that improves the reliability of the charging process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is: to provide a power bank. The power bank includes a charging body, a wireless charging component, and a clamping member. The charging body is provided with a battery. The wireless charging component is disposed on the charging body and is used to charge the device. The wireless charging component is electrically connected to the battery. The charging body forms a charging loading area corresponding to the wireless charging component. The clamping member includes a connecting part and a positioning part connected to each other. The connecting part is movably connected to the charging body and is used to move relative to the charging body in a first direction so that the positioning part moves closer to or further away from the charging loading area. The positioning part is used to confine the device in the charging loading area.

[0006] The beneficial effects of this application are as follows: Unlike existing technologies, this power bank includes a charging body, a wireless charging component, and a clamping device. The charging body is equipped with a battery, and the wireless charging component is disposed within the charging body and used to charge the device. The wireless charging component is electrically connected to the battery. The charging body forms a charging loading area corresponding to the wireless charging component. The clamping device includes a connecting part and a positioning part connected to each other. The connecting part is movably connected to the charging body and is used to move relative to the charging body in a first direction so that the positioning part moves closer to or further away from the charging loading area. The positioning part is used to confine the device within the charging loading area, thereby limiting the power consumption. The device is offset from the charging position corresponding to the wireless charging component to improve the reliability of the charging process. It also prevents the device from detaching from the power bank, thus keeping the device and power bank relatively fixed. This improves the reliability of the charging process and makes it easier to carry the device and power bank. In addition, the positioning unit can adjust the distance between itself and the charging loading area. On the one hand, the positioning unit can limit the movement of devices of different sizes, which helps to improve the compatibility of the power bank with different types and specifications of devices. On the other hand, when the power bank is not charging the device, the distance between the positioning unit and the charging loading area can be adjusted to be as close as possible, which helps to reduce the space occupied by the power bank and make it easier to store the power bank.

[0014] 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.

[0015] Through long-term research, the inventors have discovered that when people carry portable electrical devices out, they can charge these devices using a power bank. Currently, wireless charging technology is used in power banks. However, when charging devices with wireless charging capabilities, the devices are prone to deviating from the charging position or even slipping off the power bank, causing instability in the charging process. To solve this technical problem, this application provides the following embodiments.

[0016] like Figures 1 to 3 As shown in the embodiment of this application, the power bank 1 includes a charging body 100, a wireless charging component 200, and a clamping member 300. The charging body 100 is provided with a battery. The wireless charging component 200 is disposed on the charging body 100 and used to charge a device. The wireless charging component 200 is electrically connected to the battery. The charging body 100 forms a charging loading area 101 corresponding to the wireless charging component 200. The clamping member 300 includes a connecting portion 310 and a positioning portion 320 connected to each other. The connecting portion 310 is movably connected to the charging body 100 and is used to move relative to the charging body 100 along a first direction D1 so that the positioning portion 320 approaches or moves away from the charging loading area 101. The positioning portion 320 is used to confine the device within the charging loading area 101.

[0017] The power bank 1 can be used to charge electrical devices, which may include smartwatches, mobile phones, earphones, etc. The wireless charging component 200 can be used to wirelessly charge electrical devices. For example, the wireless charging component 200 includes a transmitting coil, which can transmit electrical energy to the electrical device based on the principle of electromagnetic induction.

[0018] The charging loading area 101 can be used to place electrical devices, so that the wireless charging component 200 can charge the electrical devices placed in the charging loading area 101. The clamp 300 is used to limit the electrical devices placed in the charging loading area 101, thereby preventing the electrical devices from deviating from the corresponding charging position of the wireless charging component 200, so as to improve the reliability of the charging process. The clamp 300 can also prevent the electrical devices from detaching from the power bank 1, so that the electrical devices and the power bank 1 are relatively fixed, easy to carry, and not easy to lose.

[0019] The clamping part 300 is connected to the charging body 100 via the connecting part 310, and the positioning part 320 ensures that the power device is stably positioned in the charging loading area 101. Specifically, by moving the connecting part 310 relative to the charging body 100, the positioning part 320 can move closer to or further away from the charging loading area 101. When the positioning part 320 moves closer to the charging loading area 101, it can limit the power device through a stop action; when the positioning part 320 moves away from the charging loading area 101, it can release the limiting effect on the power device. In addition, by moving the connecting part 310 relative to the charging body 100, the positioning part 320 can adjust the distance between itself and the charging loading area 101, thereby enabling the positioning part 320 to limit power devices of different sizes, which helps to improve the compatibility of the power bank 1 with power devices of different types and specifications. For example, if the device is a mobile phone, the positioning unit 320 can abut against the phone along its thickness or width to limit its movement. Different brands and models of mobile phones may have different thicknesses and widths. By adjusting the positioning unit 320, the distance between it and the charging mounting area 101 can be adjusted, thus limiting the movement of mobile phones of different sizes. As another example, if the device is a smartwatch, the positioning unit 320 can abut against the smartwatch along its thickness or width (excluding the strap) to limit its movement. Different brands and models of smartwatches may have different thicknesses and widths. By adjusting the positioning unit 320, the distance between it and the charging mounting area 101 can be adjusted, thus limiting the movement of smartwatches of different sizes.

[0020] Before installing the electrical equipment in the charging loading area 101, the distance between the positioning part 320 and the charging loading area 101 can be adjusted to a larger distance, thereby facilitating the installation of the electrical equipment in the charging loading area 101. When the power bank 1 is not charging the electrical equipment, the distance between the positioning part 320 and the charging loading area 101 can be adjusted to a minimum, which helps to reduce the space occupied by the power bank 1 and facilitates the storage of the power bank 1.

[0021] In some embodiments, the positioning part 320 and the connecting part 310 are fixedly disposed relative to each other, and the positioning part 320 moves relative to the charging body 100 along the first direction D1 with the connecting part 310.

[0022] In some embodiments, when the positioning part 320 is in a state away from the charging loading area 101, the charging loading area 101 is disposed opposite to the positioning part 320 along the first direction D1. For example, when the electrical device is installed in the charging loading area 101, the electrical device can abut against the charging loading area 101 along the first direction D1. In other embodiments, when the electrical device is installed in the charging loading area 101, the first direction D1 may intersect the arrangement direction of the electrical device and the charging loading area 101, for example, the arrangement direction of the electrical device and the charging loading area 101 may be perpendicular to the first direction D1.

[0023] In some embodiments, the positioning part 320 is rotatably connected to the charging body 100. When the positioning part 320 moves along the first direction D1, the movement trajectory of the positioning part 320 is curved (e.g., an arc). In other embodiments, when the positioning part 320 moves along the first direction D1, the movement trajectory of the positioning part 320 is straight.

[0024] In some embodiments, the positioning part 320 presses the electrical device against the charging loading area 101, restricting the sliding of the electrical device in the charging loading area 101 by the pressing action. In other embodiments, the number of positioning parts 320 is at least two. When the at least two positioning parts 320 are close to the charging loading area 101, they can converge to clamp the electrical device, restricting the sliding of the electrical device in the charging loading area 101 by the clamping action. When the at least two positioning parts 320 are far away from the charging loading area 101, they can disperse to release the electrical device.

[0025] In some embodiments, the wireless charging component 200 is mounted on the outside of the charging body 100 and exposed to the outside. When a device is installed in the charging loading area 101, the wireless charging component 200 is exposed to the device, and the outer surface of the wireless charging component 200 is located in the charging loading area 101. In other embodiments, the wireless charging component 200 is disposed inside the charging body 100 and close to the charging loading area 101.

[0026] The power bank 1 includes a charging body 100, a wireless charging component 200, and a clamping member 300. The charging body 100 is equipped with a battery. The wireless charging component 200 is disposed on the charging body 100 and used to charge electrical devices. The wireless charging component 200 is electrically connected to the battery. The charging body 100 forms a charging loading area 101 corresponding to the wireless charging component 200. The clamping member 300 includes a connecting part 310 and a positioning part 320 connected to each other. The connecting part 310 is movably connected to the charging body 100 and is used to move relative to the charging body 100 along a first direction D1 so that the positioning part 320 moves closer to or further away from the charging loading area 101. The positioning part 320 is used to confine the electrical device in the charging loading area 101. The positioning unit 320 is designed to limit the movement of the device from the charging position corresponding to the wireless charging component 200, thereby improving the reliability of the charging process. It also prevents the device from detaching from the power bank 1, thus keeping the device and power bank 1 relatively fixed. This improves the reliability of the charging process and makes it easier to carry the device and power bank 1. In addition, the positioning unit 320 can adjust the distance between itself and the charging loading area 101. On the one hand, the positioning unit 320 can limit the movement of devices of different sizes, which helps to improve the compatibility of the power bank 1 with devices of different types and specifications. On the other hand, when the power bank 1 is not charging the device, the distance between the positioning unit 320 and the charging loading area 101 can be adjusted to be as close as possible, which helps to reduce the space occupied by the power bank 1 and make it easier to store the power bank 1.

[0027] Optionally, such as Figures 3 to 6 As shown, the clamping member 300 is provided with a locking part 330. The power bank 1 also includes a locking member 120 movably mounted on the charging body 100. The locking member 120 moves along the second direction D2 to engage or disengage from the locking part 330, and the second direction D2 intersects with the first direction D1.

[0028] That is, the first direction D1 and the second direction D2 are set at an angle, for example, the angle between the first direction D1 and the second direction D2 is 90°. In some embodiments, the power bank 1 is approximately a cuboid with unequal length, width and thickness. The two faces with the largest area of ​​the cuboid are set opposite to each other along the first direction D1, and the two faces with medium area of ​​the cuboid are set opposite to each other along the second direction D2. That is, the first direction D1 is the thickness direction of the power bank 1, and the second direction D2 is the width direction of the power bank 1.

[0029] This helps maintain the stable position of the positioning part 320. When the device is charging, the engagement of the locking member 120 with the locking part 330 enhances the limiting effect of the positioning part 320 on the device, thereby improving the stability of the charging process. When the power bank 1 is not charging the device, the engagement of the locking member 120 with the locking part 330 restricts the sliding of the positioning part 320, facilitating the storage of the power bank 1.

[0030] Optionally, such as Figures 3 to 6 As shown, the power bank 1 also includes an elastic reset member 125, which abuts against the locking member 120 and the charging body 100 respectively. When the locking member 120 disengages from the locking portion 330, the elastic reset member 125 elastically deforms so as to drive the locking member 120 into the locking portion 330.

[0031] The charging body 100 provides support for the elastic reset member 125. The elastic reset member 125 can apply a force to the locking member 120 through elastic action, so that the locking member 120 is stably engaged with the locking part 330. Under the action of external force, the locking member 120 can disengage from the locking part 330, and at the same time, the elastic reset member 125 can undergo elastic deformation. When the external force is removed, the elastic reset member 125 can elastically deform and reset, and drive the locking member 120 to engage with the locking part 330.

[0032] Optionally, such as Figures 3 to 6 As shown, the end of the locking member 120 away from the locking portion 330 is also provided with a pressing portion 121 and a mounting portion 124. The charging body 100 is provided with a mounting groove 132 having a supporting surface 131. The pressing portion 121 and the mounting portion 124 are movably inserted into the mounting groove 132. The elastic reset member 125 abuts against the supporting surface 131 and the pressing portion 121, and the elastic reset member 125 is sleeved on the outer periphery of the mounting portion 124. Furthermore, the mounting portion 124 and the pressing portion 121 can be integrally formed and connected.

[0033] The user-applied external force can act on the pressing part 121. Under the action of the external force, the locking member 120 can disengage from the locking part 330, and the elastic reset member 125 can undergo elastic deformation. By providing the pressing part 121, the user can easily adjust the position of the positioning part 320. By providing the support surface 131, the elastic reset member 125 can be easily installed, and the support surface 131 can also stop the pressing part 121 to prevent it from entering the charging body 100.

[0034] Optionally, the elastic reset element 125 is a spring.

[0035] Optionally, such as Figures 3 to 6As shown, the clamping member 300 is provided with a plurality of locking parts 330, which are configured to move along the first direction D1 with the connecting part 310, and the plurality of locking parts 330 are arranged along the first direction D1.

[0036] By setting multiple locking parts 330, after the connecting part 310 moves relative to the charging body 100 along the first direction D1, causing the positioning part 320 to move closer to or further away from the charging loading area 101 and the multiple locking parts 330 move relative to the locking member 120, there are still locking parts 330 among the multiple locking parts 330 that can engage with the locking member 120. This helps the positioning part 320 maintain positional stability after adjusting its position, thereby improving the limiting effect of the positioning part 320 on the electrical equipment.

[0037] Optionally, such as Figures 3 to 6 As shown, multiple locking portions 330 are disposed on the connecting portion 310, and the locking member 120 is provided with a limiting hole 122. The connecting portion 310 and the multiple locking portions 330 are movably disposed in the limiting hole 122 along the first direction D1. The locking portion 330 has a groove 331, and the wall of the limiting hole 122 is used to insert into the groove 331 so that the locking member 120 engages with the locking portion 330. The clamping member 300 may also include a flange portion 311 connected to the connecting portion 310, and the locking member 120 is also used to stop the flange portion 311 to prevent the connecting portion 310 from disengaging from the limiting hole 122.

[0038] When the locking member 120 engages with the locking portion 330, a portion of the wall of the limiting hole 122 inserts into the groove 331. The wall of the limiting hole 122 is annular, which helps to improve the deformation resistance of the portion of the locking member 120 inserted into the groove 331. During assembly, the connecting portion 310 can be passed through the limiting hole 122 first, and then the connecting portion 310 and the flange portion 311 can be connected. By providing the flange portion 311, the connecting portion 310 can also be prevented from detaching from the charging body 100.

[0039] Furthermore, the flange portion 311 is disposed adjacent to a plurality of locking portions 330 to restrict the plurality of locking portions 330 from disengaging from the limiting hole 122.

[0040] Optionally, such as Figures 3 to 6 As shown, the connecting part 310 has a columnar structure, and its two ends are connected to the positioning part 320 and the flange part 311, respectively. Furthermore, a clearance groove 312 is provided between the two ends of the connecting part 310. The clearance groove 312 is used to avoid electrical equipment to reduce the probability of interference between the connecting part 310 and the electrical equipment.

[0041] Optionally, such as Figures 3 to 6As shown, the locking member 120 may further include a locking piece 123, with a limiting hole 122 formed in the locking piece 123. The sheet-like structure of the locking piece 123 facilitates engagement with the locking portion 330; for example, the sheet-like structure of the locking piece 123 facilitates insertion into the groove 331. The mounting portion 124 can be connected between the locking piece 123 and the pressing portion 121. Specifically, the locking piece 123 and the mounting portion 124 can be connected by screws.

[0042] Furthermore, the locking piece 123 can be bent, which increases the contact area between the locking piece 123 and the mounting part 124, making it easier to connect the locking piece 123 and the mounting part 124.

[0043] Optionally, such as Figure 6 and Figure 7 As shown, each locking portion 330 has a locking surface 332 and a guide surface 333. Multiple locking surfaces 332 and multiple guide surfaces 333 are arranged alternately along a first direction D1, and adjacent guide surfaces 333 are inclined relative to the locking surface 332. The locking surface 332 faces the positioning portion 320, and the guide surface 333 faces away from the positioning portion 320. The locking surface 332 abuts against the locking member 120 to engage the locking member 120 with the locking portion 330, thereby restricting the positioning portion 320 from moving away from the charging loading area 101. The guide surface 333 guides the locking member 120 away from the locking portion 330 to allow the positioning portion 320 to move towards the charging loading area 101.

[0044] Specifically, the angle between the locking surface 332 and the first direction D1 and the second direction D2 is small, so that the locking member 120 has a limiting effect on the locking surface 332. For example, the locking surface 332 is parallel to both the first direction D1 and the second direction D2, which helps to enhance the limiting effect of the locking member 120 on the locking surface 332. The guide surface 333 is inclined relative to the first direction D1 and the second direction D2. By setting the guide surface 333 to be inclined relative to the first direction D1 and the second direction D2, when the locking part 330 is subjected to force along the first direction D1, it will drive the locking member 120 to move along the second direction D2, causing the locking member 120 to disengage from the locking part 330.

[0045] Optionally, the locking member 120 has a mating locking surface and a mating guiding surface. The mating locking surface is disposed away from the positioning portion 320, and the mating guiding surface is disposed towards the positioning portion 320. The mating locking surface is used to abut against the locking portion 330 so that the locking member 120 is engaged with the locking portion 330, thereby restricting the movement of the positioning portion 320 away from the charging loading area 101. The mating guiding surface is disposed at an angle relative to the first direction D1 and the second direction D2, and is used to guide the locking member 120 away from the locking portion 330 so that the positioning portion 320 moves towards the charging loading area 101.

[0046] Specifically, the angle between the mating locking surface and the first direction D1 and the second direction D2 is small, so that the locking member 120 has a limiting effect on the locking part 330. For example, the mating locking surface is parallel to both the first direction D1 and the second direction D2, which helps to enhance the limiting effect of the locking member 120 on the locking part 330. By setting the mating guide surface to be inclined relative to the first direction D1 and the second direction D2, when the locking part 330 is subjected to force along the first direction D1, it will drive the locking member 120 to move along the second direction D2, causing the locking member 120 to disengage from the locking part 330. The setting of the mating locking surface and the mating guide surface can be referred to the setting of the locking surface 332 and the guide surface 333 in the attached drawings.

[0047] Before installation in the charging loading area 101, the distance between the positioning part 320 and the charging loading area 101 can be adjusted to a relatively loose state relative to the electrical equipment, so as to facilitate the placement of the electrical equipment in the charging loading area 101. By setting the guide surface 333 and / or the cooperating guide surface, after the electrical equipment is placed in the charging loading area 101, it is not necessary to press the pressing part 121. The positioning part 320 can be pressed to move along the first direction D1 towards the charging loading area 101 and simultaneously drive the locking member 120 to disengage from the locking part 330. After the positioning part 320 moves to press the electrical equipment, the locking member 120 automatically locks into the locking part 330, thereby facilitating the user's charging operation.

[0048] Optionally, such as Figures 3 to 6 As shown, the power bank 1 includes an elastic member 340, which abuts against the charging body 100 and the clamping member 300. The elastic member 340 is used to drive the clamping member 300 to move relative to the charging body 100 along the first direction D1 through elastic deformation, so that the positioning part 320 moves away from the charging body 100.

[0049] The positioning unit 320 may have a release position away from the charging loading area 101 and a storage position close to the charging loading area 101, and may move between the release position and the storage position. When the positioning unit 320 is in the release position, it can be used to limit the electrical device, and when the positioning unit 320 is idle, it can be in the storage position to reduce the space occupied by the power bank 1.

[0050] When the positioning part 320 is in the storage position and between the release position and the storage position, the elastic member 340 can be compressed. When the elastic member 340 returns to its shape, it can drive the clamping member 300 to move relative to the charging body 100 along the first direction D1 through elastic deformation, so as to drive the positioning part 320 to move to the release position.

[0051] Furthermore, due to the engaging action of the locking member 120 on the locking portion 330, the positioning portion 320 is stably positioned in the retracted position or stably positioned between the released position and the retracted position. When the locking member 120 disengages from the locking portion 330, the positioning portion 320 can move to the released position under the action of the elastic member 340.

[0052] Furthermore, the elastic member 340 abuts against one end of the connecting flange 311 of the connecting portion 310 and the charging body 100.

[0053] Optionally, the elastic element 340 is a spring.

[0054] Optionally, such as Figures 1 to 3 As shown, the outer wall surface 133 of the charging body 100 forming the charging loading area 101 is provided with a receiving groove 134. The positioning part 320 can move along the direction close to the charging loading area 101 and be stored in the receiving groove 134.

[0055] This configuration allows the device to be held between the positioning part 320 and the charging loading area 101 along the first direction D1 during charging, enhancing the limiting effect of the positioning part 320 on the device and improving charging reliability. After the device is removed from the charging loading area 101, the positioning part 320 can move along the first direction D1 towards the charging loading area 101 until it is stored in the receiving slot 134.

[0056] The outer wall surface 133 of the charging body 100 forming the charging loading area 101 is the outer side of the outer shell 130 facing away from the battery 110. By providing the receiving groove 134, the positioning part 320 can be stored when it is not in use, which can reduce the space occupied by the power bank 1, protect the positioning part 320, reduce interference to facilitate charging of large-sized electrical devices, and make the power bank 1 look more aesthetically pleasing.

[0057] Furthermore, the receiving cavity 140 is connected to the receiving groove 134. When the positioning part 320 is housed in the receiving groove 134, that is, in the above-mentioned housed position, most of the connecting part 310 is located in the receiving cavity 140, and the remaining part of the connecting part 310 is located in the receiving groove 134.

[0058] Optionally, such as Figures 1 to 3 As shown, the wireless charging component 200 is disposed on the outer wall surface 133. The receiving groove 134 may be disposed on the periphery of the wireless charging component 200. Further, the positioning part 320 has a ring structure, and the receiving groove 134 has a ring structure and is disposed around the wireless charging component 200. Further, the receiving groove 134 may be disposed at a distance from the wireless charging component 200.

[0059] This arrangement allows the wireless charging component 200 and the receiving slot 134 to be compactly arranged on the outer wall surface 133. Simultaneously, the positioning part 320 does not interfere with the wireless charging component 200, facilitating its storage. It also ensures balanced force distribution between the corresponding parts of the device and the wireless charging component 200. By placing the wireless charging component 200 on the outer wall surface 133, it is easier for the component to be close to the device, facilitating wireless charging.

[0060] Optionally, such as Figures 4 to 6 As shown, the positioning part 320 includes a support part 321 and an elastic part 322. The elastic part 322 is disposed on the side of the support part 321 facing the charging loading area 101, and the elastic part 322 is used to abut against the electrical equipment.

[0061] By providing the support portion 321, the elastic portion 322 can be supported, ensuring that the positioning portion 320 has sufficient mechanical strength to guarantee the limiting effect on the electrical equipment. The elastic portion 322 is elastic and can undergo elastic deformation when subjected to a certain range of force, thereby forming a buffer between the support portion 321 and the electrical equipment, providing a shock-absorbing effect and reducing the risk of mechanical damage to the surface of the electrical equipment. Providing the elastic portion 322 also allows the positioning portion 320 to fully and tightly abut against the electrical equipment, which is beneficial for firmly and stably limiting the electrical equipment.

[0062] Optionally, the elastic part 322 may be made of elastic materials such as silicone or rubber.

[0063] Optionally, such as Figures 4 to 6 As shown, the positioning part 320 has a plurality of limiting protrusions 323 protruding toward the charging body 100. The plurality of limiting protrusions 323 are distributed at intervals along the circumference of the positioning part 320, and the plurality of limiting protrusions 323 are used to abut against the electrical equipment in different directions.

[0064] By setting the limiting protrusion 323, the sliding of the electrical equipment along the direction intersecting with the first direction D1 can be restricted, which is conducive to firmly and stably limiting the electrical equipment and improving the reliability of the charging process.

[0065] Optionally, the multiple limiting protrusions 323 may be made of materials including elastic silicone, rubber, etc.

[0066] Optionally, the elastic portion 322 includes a plurality of limiting protrusions 323. The elastic portion 322 is connected to the support portion 321 by means of adhesive bonding or the elastic portion 322 is molded onto the support portion 321 by means of injection molding.

[0067] Optionally, such as Figure 3 and Figure 5As shown, the power bank 1 also includes a circuit board 400 and a charging cable 500. The circuit board 400 is electrically connected to the battery 110, the charging cable 500 and the wireless charging component 200 respectively. The circuit board 400 is used to control the battery 110 to supply power to the charging cable 500 and the wireless charging component 200.

[0068] With this configuration, Power Bank 1 can charge both wireless charging and wired charging devices, which helps to broaden its application range.

[0069] Optionally, the power bank 1 also includes two circuit boards 400 and a charging cable 500. One circuit board 400 is electrically connected between the battery 110 and the charging cable 500 to control the battery 110 to supply power to the charging cable 500. The other circuit board 400 is electrically connected between the battery 110 and the wireless charging component 200 to control the battery 110 to supply power to the wireless charging component 200.

[0070] This setup reduces interference between the wired and wireless charging functions of the power bank 1, improving charging efficiency.

[0071] Optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, the charging cable 500 includes a charging connector 510 and a cable body 520 connected together. The end of the cable body 520 away from the charging connector 510 is connected to a circuit board 400 located inside the charging body 100. The charging body 100 has a cable outlet 135 through which the cable body 520 extends from inside the charging body 100. A limiting portion 136 is also provided on the outer side of the charging body 100, spaced apart from the cable outlet 135. The limiting portion 136 is used to prevent the charging connector 510 from detaching from the charging body 100. The distance L1 between the limiting portion 136 and the cable outlet 135 is less than the length of the portion of the cable body 520 outside the charging body 100.

[0072] This design allows the charging cable 500 to be used as a carrying strap. Specifically, when the charging cable 500 is charging a device, the limiting part 136 can be controlled to release the charging connector 510, and then the charging connector 510 can be inserted into the device for charging. The charging connector 510 can have a micro USB interface, a Type-C interface, or a Lightning interface. When the charging cable 500 is not in use, the limiting part 136 can be controlled to limit the charging connector 510, allowing the power bank 1 to be lifted via the carrying strap 520, thus facilitating its carrying.

[0073] For example, when the charging connector 510 is subjected to a force toward the outlet 135, the limiting part 136 prevents the charging connector 510 from detaching from the charging body 100 by stopping the charging connector 510 from approaching the outlet 135. Alternatively, the limiting part 136 may include one of a clip or a latch.

[0074] Optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, the limiting part 136 has a connecting limiting groove 137 and a stop hole 138. The limiting groove 137 is located at the end of the stop hole 138 away from the cable outlet 135, and the limiting groove 137 is used to accommodate the charging connector 510. The cable 520 passes through the stop hole 138, and the size of the stop hole 138 is smaller than the size of the charging connector 510, so as to stop the charging connector 510, which is accommodated in the limiting groove 137, from moving into the stop hole 138.

[0075] When charging the device with the charging cable 500, the charging connector 510 can be pulled out from the limiting groove 137. When the charging cable 500 needs to be used as a carrying lanyard, the cable body 520 can be pulled to allow the charging connector 510 to enter the limiting groove 137. In this way, the charging cable 500 can be used as a lanyard. During the assembly of the power bank 1, the end of the cable body 520 away from the charging connector 510 can be passed through the stop hole 138 first, and then connected to the circuit board 400.

[0076] Optionally, the limiting part 136 is provided with a magnetic attracting element, which is used to limit the charging connector 510 by magnetic attraction. For example, the magnetic attracting element is provided in the limiting groove 137. In this way, the limiting effect of the limiting part 136 on the charging connector 510 can be improved.

[0077] Optionally, such as Figures 2 to 6 As shown, the charging body 100 has a housing 130 and a bottom cover 139, which are connected and enclose a receiving cavity 140, in which the battery 110 is located. The housing 130 forms a charging loading area 101 on its outer side opposite to the battery 110. The receiving cavity 140 communicates with a mounting groove 132, and a locking piece 123 is movably located within the receiving cavity 140 along a second direction D2. A connecting portion 310 extends movably through the housing 130 from within the receiving cavity 140 to the outside and connects to a positioning portion 320. A plurality of locking portions 330 are at least partially located within the receiving cavity 140, a flange portion 311 is located within the receiving cavity 140, and an elastic member 340 is located within the receiving cavity 140 and abuts against the bottom cover 139 and the connecting portion 310.

[0078] Optionally, such as Figure 3 and Figure 5As shown, a fixing groove 141 is provided on the outer side of the outer casing 130, and the wireless charging component 200 is disposed in the fixing groove 141. The circuit board 400 is disposed in the receiving cavity 140, and the wires of the wireless charging component 200 extend through the bottom wall of the fixing groove 141 into the receiving cavity 140 and connect to the circuit board 400. The outlet 135 communicates with the receiving cavity 140, and the end of the charging cable 500 away from the charging connector 510 is connected to the circuit board 400 in the receiving cavity 140.

[0079] Optionally, such as Figures 2 to 6 As shown, the housing 130 has a first housing portion 142 and a second housing portion 143 adjacent to each other. A charging loading area 101 is formed on the first housing portion 142, and a connecting portion 310 is connected to the edge of the first housing portion 142 near the second housing portion 143. In this way, when the electrical device is placed in the charging loading area 101, the obstruction and interference of the connecting portion 310 on the placement of the electrical device can be reduced, so as to facilitate the placement of the electrical device in the charging loading area 101.

[0080] Optionally, such as Figures 2 to 6 As shown, the outer casing 130 may have a first casing portion 142 and a second casing portion 143 opposite to the bottom cover 139. Both the first casing portion 142 and the second casing portion 143 are connected to the bottom cover 139 through a side wall portion 146 of the outer casing 130. The battery 110 is located between the second casing portion 143 and the bottom cover 139. The circuit board 400, the locking piece 123, the elastic member 340, and the flange portion 311 are located between the first casing portion 142 and the bottom cover 139. The connecting portion 310 passes through the first casing portion 142. The receiving groove 134 and the wireless charging assembly 200 are provided on the side of the first casing portion 142 opposite to the circuit board 400. Two first corner areas 144 and two second corner areas 145 are formed at the four corners of the outer periphery of the receiving groove 134 on the first housing part 142. The two first corner areas 144 are respectively located at the two corners of the outer wall surface 133. The two second corner areas 145 are disposed adjacent to the second housing part 143. The connecting part 310 passes through one of the second corner areas 145. The pressing part 121 is disposed on the side wall part 146 between the other second corner area 145 and the bottom cover 139.

[0081] In this way, on the one hand, the connecting part 310, the receiving groove 134, and the wireless charging component 200 can be compactly arranged on the outside of the first housing part 142, and the outside of the second housing part 143 can be smooth and flat, which helps to improve the appearance of the power bank 1. On the other hand, the circuit board 400, the locking member 120, the elastic member 340, the flange part 311, and the connecting part 310 inside the receiving cavity 140 can be compactly arranged, which helps to leave more installation space for the battery 110, thereby helping to improve the volumetric energy density of the power bank 1. By passing the connecting part 310 through one of the second corner areas 145, the obstruction of the connecting part 310 to the electrical device can be reduced when the electrical device is placed in the charging loading area 101, so as to facilitate the placement of the electrical device in the charging loading area 101.

[0082] Furthermore, such as Figure 5 As shown, the cable outlet 135 is closer to the first housing portion 142 than the second housing portion 143. Specifically, the cable outlet 135 is located in the portion of the side wall portion 146 between one of the first corner areas 144 and the bottom cover 139. In this way, the cable outlet 135 is kept away from the battery 110, which avoids the top-heavy situation of the power bank 1 due to the weight of the battery 110 when the user carries it, and also makes it easier for the user to observe the device.

[0083] In summary, this embodiment can limit the positioning of electrical devices placed in the charging loading area 101, thereby restricting the electrical devices from deviating from the charging position corresponding to the wireless charging component 200, thus improving the reliability of the charging process. It can also prevent the electrical devices from detaching from the power bank 1, thereby making the electrical devices and the power bank 1 relatively fixed, easy to carry, and less likely to be lost. The positioning part 320 can be adjusted in distance from the charging loading area 101, so that the positioning part 320 can limit the positioning of electrical devices of different sizes, which is beneficial to improving the compatibility of the power bank 1 with electrical devices of different types and specifications. Before installing the electrical devices in the charging loading area 101, the distance between the positioning part 320 and the charging loading area 101 can be adjusted to a relatively loose state relative to the electrical devices, thereby facilitating the installation of the electrical devices in the charging loading area 101. When the power bank 1 is not charging the electrical devices, the distance between the positioning part 320 and the charging loading area 101 can be adjusted to the closest possible distance, which is beneficial to reducing the space occupied by the power bank 1, so as to facilitate the storage of the power bank 1.
