[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] This utility model embodiment provides a portable power supply, such as... Figure 1As shown, the power bank includes a housing 1, a control circuit board (not shown), a charging cable 3, and a handle connector 4. The control circuit board is installed inside the housing 1, and one end of the charging cable 3 is electrically connected to the control circuit board. The charging cable 3 is led out from inside the housing 1, and the handle connector 4 is fixedly installed on the charging cable 3. The handle connector 4 has a clamping groove 4211, and the charging head 32 of the charging cable 3 can be detachably clamped into the clamping groove 4211 to form a handle structure.

[0031] The portable power bank of this invention features a separate handle connector 4 on the charging cable 3. The handle connector 4 has a locking groove 4211, into which the charging head 32 is inserted to form a handle structure, facilitating carrying or hanging storage. This eliminates the need for a storage slot on the housing 1 to hold and secure the charging head 32, thus avoiding the high design requirements of the housing 1 and the increased complexity of the overall power bank design. Furthermore, the handle connector 4, as an independent component, does not interfere with the housing 1 or internal components of the power bank, allowing for greater design freedom and lower design requirements.

[0032] The handle connector 4 forms a carrying handle structure, allowing users to easily hold the power bank or hang it on a backpack or wrist, greatly improving its portability. The charging cable 3 is secured by the handle connector 4, preventing tangling and loss, and also providing some protection for the cable, extending its lifespan. The handle connector 4 not only functions as a carrying handle but also serves as a storage device for the charging head 32, making the overall design of the power bank more concise and practical.

[0033] Specifically, such as Figures 2 to 8 As shown, the handle connector 4 includes an outer base 41 and an inner pressure member 42, with the inner pressure member 42 fitted into the outer base 41. The outer base 41 has a first mounting groove 411 extending from one side to the other, and the inner pressure member 42 has a second mounting groove 4221 corresponding to the first mounting groove 411. The first mounting groove 411 and the second mounting groove 4221 engage. The charging cable 3 is fixedly installed in the first mounting groove 411 and the second mounting groove 4221. Through the fitted installation of the outer base 41 and the inner pressure member 42, and the engagement of the first mounting groove 411 and the second mounting groove 4221, the charging cable 3 can be securely fixed in the handle connector 4, improving the structural stability of the entire power bank. This split design of the handle connector 4 makes the assembly of the charging cable 3 and the handle connector 4 more convenient. Specifically, the dimensions of the first mounting groove 411 and the second mounting groove 4221 can be adjusted according to different specifications of the charging cable 3. The outer seat 41 and the inner pressure member 42 can be fitted together by means of snap-fit, thread or interference fit, so as to ensure that the two are tightly connected and easy to assemble.

[0034] In the first mounting slot 411 and the second mounting slot 4221, the charging cable 3 is provided with a locking part 31; the first mounting slot 411 is provided with a first locking slot 412, and the second mounting slot 4221 is provided with a second locking slot 4222. The first locking slot 412 and the second locking slot 4222 are engaged, and the locking part 31 is locked in the first locking slot 412 and the second locking slot 4222.

[0035] Through the cooperation of the locking part 31 and the locking groove, the charging cable 3 can be more firmly fixed in the first mounting groove 411 and the second mounting groove 4221, preventing the charging cable 3 from loosening or sliding due to external forces during use, thus improving the reliability of the handle structure. The design of the locking part 31 and the locking groove allows the charging cable 3 to be quickly and accurately positioned during installation, simplifying the installation process and improving production efficiency. Specifically, the locking part 31 can be a protrusion, an annular retaining ring, or other structure provided on the charging cable 3; it can be integrally formed on the charging cable 3; or it can be a part that is independently formed and then glued or interference-fitted onto the charging cable 3. Its shape and size match the first locking groove 412 and the second locking groove 4222, ensuring that the locking part 31 can be accurately locked in the locking groove. The depth and width of the first locking groove 412 and the second locking groove 4222 can be adjusted according to the size of the locking part 31 to ensure that the locking part 31 can be securely locked in the locking groove.

[0036] A insertion slot 4211 is formed on the inner pressure member 42, and an insertion port 413 is provided on the side of the outer seat 41. The insertion port 413 mates with the opening of the insertion slot 4211; the charging head 32 is inserted into the insertion slot 4211 through the insertion port 413. The design of the insertion port 413 and the insertion slot 4211 allows the charging head 32 to be quickly and easily inserted and removed, improving the user experience. The insertion slot 4211 securely fixes the charging head 32 inside, preventing it from detaching and improving the reliability of the handle structure. The shape and size of the insertion port 413 match the shape of the charging head 32, ensuring that the charging head 32 can be smoothly inserted into the insertion slot 4211 while preventing dust and debris from entering. The shape and size of the insertion slot 4211 also match the shape of the charging head 32. For example, if the charging head 32 has a USB interface, the insertion slot 4211 will have the corresponding USB interface shape to ensure that the charging head 32 can be tightly inserted. The interior of the insertion slot 4211 can be provided with an elastic buckle or a female connector that is compatible with the charging head 32. When the charging head 32 is inserted into the insertion slot 4211, the elastic buckle or female connector can securely fix the charging head 32 in the insertion slot 4211 to prevent it from loosening.

[0037] The inner pressure member 42 includes a main body 421 and a protruding part 422. The protruding part 422 is connected to one end of the main body 421 and extends outward relative to the side of the main body 421, so that the overall shape of the inner pressure member 42 is 7-shaped. The second mounting groove 4221 is provided on the side of the protruding part 422 facing the interior of the outer seat 41, and the insertion groove 4211 is formed on the side of the main body 421. The 7-shaped design of the inner pressure member 42 allows for a reasonable layout of the second mounting groove 4221 and the insertion groove 4211, making full use of space and improving the structural compactness and stability of the handle connector 4. The main body 421 and the protruding part 422 of the inner pressure member 42 perform different functions. The main body 421 is used to set the insertion groove 4211, and the protruding part 422 is used to set the second mounting groove 4221. The main body 421 and the protruding part 422 can be manufactured by integral molding, and the integrally molded inner pressure member 42 has higher strength and reliability. The shape and size of the second mounting slot 4221 are designed according to the shape of the charging cable 3 to ensure that the charging cable 3 can be securely fixed therein.

[0038] On both sides of the protrusion 422, corresponding to the second mounting groove 4221, there are locking protrusions 4223. On both sides of the outer seat 41, corresponding to the first mounting groove 411, there are locking slots 414, and the locking protrusions 4223 are engaged with the locking slots 414. Through the cooperation of the locking protrusions 4223 and the locking slots 414, the connection between the inner pressure member 42 and the outer seat 41 is more secure, preventing the inner pressure member 42 from loosening or shifting during use. The locking design also makes the assembly of the inner pressure member 42 and the outer seat 41 more convenient.

[0039] Furthermore, such as Figure 1 , Figure 9 and Figure 10As shown, the power bank also includes a wireless charging pad 5. The wireless charging pad 5 contains a first wireless charging module 51 electrically connected to the control circuit board. The wireless charging pad 5 is rotatably mounted on one side of the housing 1, allowing it to be rotated and stored on the first surface 11 of the housing 1, and to be rotated upright from the first surface 11. The wireless charging pad 5 adds wireless charging functionality, enabling the power bank to support both wired and wireless charging simultaneously, meeting different user needs. The wireless charging pad 5 can be rotated and stored on the first surface 11 of the housing 1 without occupying extra space, making the power bank more portable when the wireless charging function is not in use. Users can stand the wireless charging pad 5 upright or store it as needed; the operation is simple and convenient, improving the user experience. When the wireless charging pad 5 is upright, it is convenient for users to charge their mobile phones. Specifically, the first wireless charging module 51 is a magnetic wireless charging module. The wireless charging pad 5 can be mounted on one side of the housing 1 via a hinge or pivot structure. The hinge or pivot can be made of metal or high-strength plastic material to ensure its durability and flexibility. The rotation angle of the wireless charging pad 5 can be designed according to actual usage needs. For example, it can be designed to be adjustable from 0° to 90° through a damping hinge to meet the usage needs of different scenarios. This will not be elaborated on here.

[0040] The first surface 11 has a first charging position 111, and a second wireless charging module (not shown) electrically connected to the control circuit board is disposed inside the housing 1 of the first charging position 111. The placement of the second wireless charging module on the first surface 11 of the power bank enables the power bank to support wireless charging of two devices simultaneously, improving charging efficiency. For example, the wireless charging pad 5 charges a mobile phone, and the first charging position 111 charges the earphone charging case. The first charging position 111 is located on the first surface 11 of the housing 1, making full use of the surface space of the power bank without adding extra volume. The first wireless charging module 51 and the second wireless charging module can support different wireless charging standards (such as the Qi standard), enhancing the compatibility of the power bank and meeting the charging needs of more devices; details are not elaborated here.

[0041] Specifically, the first charging position 111 protrudes from the first surface 11, and the wireless charging plate 5 has a fitting groove 52 facing the first surface 11. When the wireless charging plate 5 is housed on the first surface 11, the first charging position 111 is embedded in the fitting groove 52. The first wireless charging module 51 protrudes from the surface of the wireless charging plate 5 facing away from the first surface 11 and corresponds to the fitting groove 52. The protruding first charging position 111 provides users with a more intuitive placement position, making it convenient for users to quickly place the device on the charging position. The fitting groove 52 can accommodate the first charging position 111, improving the flatness of the wireless charging panel. The protruding first wireless charging module 51, located on the surface of the wireless charging plate 5 facing away from the first surface 11 and corresponding to the fitting groove 52, facilitates the placement and charging of mobile phones.

[0042] Specifically, the top surface of the first charging position 111 is recessed to facilitate the placement of the object being charged. The object being charged can be an earphone charging case, a watch, etc.
