[0042] Please refer to Figure 1 and Figure 2 This utility model provides a pull-rod type portable energy storage power supply, including a main body 1, a battery module, a moving component 2, and a pull rod assembly 3. The bottom surface of the main body 1 is provided with a receiving groove 11 extending in a horizontal direction; the battery module is disposed in the main body 1; the moving component 2 is disposed in the main body 1 and is used to support the movement of the main body 1; the pull rod assembly 3 is disposed in the receiving groove 11 and can extend from one end of the receiving groove 11 to the outside of the receiving groove 11 or retract into the receiving groove 11.

[0043] In this embodiment, the main body 1 is generally rectangular in shape and is assembled from multiple mounting plates. The interior of the main body 1 is a hollow cavity for accommodating the battery module and other modules, such as the inverter. The main body 1 can be made of engineering plastics, which enhance its strength, making it less susceptible to damage from external impacts and protecting the modules inside. Furthermore, engineering plastics are lightweight, reducing the overall weight of the portable energy storage power supply 100, facilitating handling and improving the user experience. Of course, this is merely an example; the specific material of the main body 1 can be determined according to actual needs, and this invention does not impose any limitations.

[0044] The moving component 2 may include several wheels. The number of wheels can be 2, 3, or 4, etc. For example, there are 2 wheels. The two wheels are located at the rear bottom of the main body 1. When the pull rod assembly 3 is used, the two wheels rotate simultaneously under the drive of the pull rod assembly 3 to support the movement of the main body 1, thereby improving the efficiency of transporting the portable energy storage power supply 100.

[0045] The receiving slot 11 on the bottom surface of the main body 1 is horizontally positioned. This means that when the portable energy storage power supply 100 is placed face down on the ground, the receiving slot 11 is parallel to the ground. Simultaneously, the pull rod assembly 3, placed in the receiving slot 11, is parallel to the ground. This ensures sufficient space for the pull rod assembly 3 on the limited bottom surface without excessively encroaching on other possible functional areas. This helps maintain the compactness of the overall structure of the portable energy storage power supply 100, allowing it to be mobile without appearing bulky due to the design of the receiving slot 11.

[0046] To facilitate long-distance transport of the portable energy storage power supply 100, the pull rod assembly 3 provided by this invention is extendable relative to the receiving slot 11. The pull rod assembly 3 can extend and retract automatically under the drive of an electronically controlled structure, or it can be manually controlled by the user. For example, the pull rod assembly 3 can extend and retract under the user's grip. When the portable energy storage power supply 100 needs to be transported, the user grips the pull rod assembly 3 and applies an outward pulling force, allowing the pull rod assembly 3 to extend from one end of the receiving slot 11 outside the slot 11, facilitating the user's transport of the portable energy storage power supply 100. When the portable energy storage power supply 100 does not need to be transported, the user applies a pushing force in the opposite direction to the pull rod assembly 3, causing the pull rod assembly 3 to retract into the receiving slot 11, preventing the pull rod assembly 3 from occupying space when not in use, and also protecting the pull rod assembly 3 from damage. Of course, the above is only an example; the specific control method can be determined according to actual needs, and this invention is not limited thereto.

[0047] The beneficial effects of this utility model are as follows:

[0048] Compared to the externally mounted pull rod assembly 3, the horizontally positioned storage slot 11 on the bottom avoids the risk of collision damage caused by the pull rod assembly 3 protruding from the side. When storing the portable power bank 100, users do not need to worry about the pull rod assembly 3 taking up too much lateral space. Whether placed in a small car trunk or a cramped corner of home storage, it can be easily placed, greatly improving the portability of storage.

[0049] Please refer to Figure 4 and Figure 7In some embodiments, the pull rod assembly 3 includes a sleeve 31 and a pull rod 32. The sleeve 31 is disposed in the receiving groove 11; the pull rod 32 is inserted into the sleeve 31 and slides with the sleeve 31, and the pull rod 32 can move relative to the sleeve 31 to extend or retract.

[0050] The sleeve 31 of this invention is fixedly disposed in the receiving groove 11, providing support and guidance for the extension and retraction of the pull rod 32. The main function of the sleeve 31 is to ensure that the pull rod 32 can slide along a specific direction and maintain its stability during the extension and retraction of the pull rod 32. It also protects the pull rod 32 and prevents it from directly rubbing or colliding with other parts of the receiving groove 11.

[0051] The pull rod 32 is inserted into and slides within the sleeve 31, ensuring that the pull rod 32 can freely extend and retract within the sleeve 31. By manually pulling or pushing the pull rod 32, it slides axially within the sleeve 31, allowing it to extend from or retract into the receiving groove 11, thus meeting the user's needs in different scenarios. For example, when the portable energy storage power supply 100 needs to be pulled, the pull rod 32 can be extended for easy gripping and application of force; when not in use, the pull rod 32 can be retracted into the sleeve 31, without affecting the overall aesthetics and storage of the portable energy storage power supply 100.

[0052] Please refer to Figure 2 In some embodiments, the receiving groove 11 has a slot 111 disposed opposite to its bottom wall, and the pull rod assembly 3 is inserted into or removed from the receiving groove 11 through the slot 111.

[0053] The slot 111 of the receiving groove 11 is an open structure opposite to the bottom wall of the groove. During the manufacturing process, operators can quickly insert the pull rod assembly 3 into the receiving groove 11 through the slot 111, improving assembly efficiency. In addition, if the pull rod assembly 3 malfunctions or is damaged during product use, users or maintenance personnel can easily remove it from the receiving groove 11 for repair or replacement without large-scale disassembly of the main body 1 of the portable energy storage power supply 100, reducing maintenance costs and difficulty.

[0054] Please refer to Figure 4 and Figure 5 In some embodiments, the pull rod assembly 3 further includes a mounting base 33, which is detachably connected to the main body 1. The mounting base 33 is provided with a mounting hole 331, and the sleeve 31 passes through the mounting hole 331 to be fixed to the mounting base 33.

[0055] The main function of the mounting base 33 is to connect the pull rod assembly 3 and the main body 1 of the portable energy storage power supply 100, fixing it to the main body 1 through a detachable connection. The detachable connection between the mounting base 33 and the main body 1 can be a bolt connection, a snap-fit ​​connection, or a tenon-and-mortise connection, etc. For example, the mounting base 33 is bolted to the bottom surface of the main body 1. The bolt connection is firm and reliable, capable of withstanding large tensile and shear forces, ensuring that the mounting base 33 will not easily loosen during use. Disassembly is simple; just use the appropriate tools to unscrew the bolts. Of course, the above is only an example; the specific connection method can be determined according to actual needs, and this utility model does not impose any limitations.

[0056] The mounting hole 331 provided by this utility model has a mounting hole 331, which can be understood as being placed in the receiving groove 11. The sleeve 31 of the pull rod assembly 3 passes through the mounting hole 331 and is fixed by the mounting seat 33, ensuring that the sleeve 31 can be stably held in the predetermined position, thereby ensuring that the pull rod 32 that cooperates with it can perform telescopic movement on the accurate axis, and ensuring that the sleeve 31 will not shake or deviate during the telescopic movement of the pull rod 32, thereby ensuring the smoothness and accuracy of the movement of the pull rod 32.

[0057] Please continue to refer to this. Figure 5 In some embodiments, the mounting base 33 includes a mounting portion 332 and two connecting portions 333 integrally formed with the mounting portion 332. The two connecting portions 333 are disposed opposite to each other on both sides of the mounting portion 332. The mounting portion 332 is configured with mounting holes 331, and the connecting portions 333 are detachably connected to the main body 1 by fasteners 4.

[0058] This can be understood as follows: the mounting part 332 is placed inside the receiving groove 11, and the mounting hole 331 constructed in the mounting part 332 mainly provides an installation position and support for the sleeve 31. The size and precision of the mounting hole 331 match the sleeve 31, which can ensure that the sleeve 31 is accurately installed on the mounting base 33, and restrict the position of the sleeve 31 during the extension and retraction of the pull rod 32, so that it can only make a small displacement along the axial direction of the mounting hole 331, thereby ensuring the accuracy and stability of the movement of the pull rod 32.

[0059] The fastener 4 can be a bolt or a clip, for example, a bolt. Tightening the bolt secures the connecting part 333 to the main body 1, ensuring the mounting base 33 is firmly installed and will not shift due to the extension or retraction of the pull rod 32. It also prevents the pull rod assembly 3 from falling off the main body 1 and being damaged due to loose mounting base 33, thus extending the service life of the pull rod assembly 3. Of course, the above is only an example; the specific type of fastener 4 can be determined according to actual needs, and this utility model does not impose any limitations.

[0060] Please refer to Figure 2 and Figure 3 In some embodiments, the bottom surface of the main body 1 is provided with a connecting groove 12 located beside the receiving groove 11 and adapted to the connecting part 333, and the connecting part 333 is accommodated in the connecting groove 12.

[0061] To improve the portability of the mounting base 33, a connecting groove 12 is provided next to the receiving groove 11. This means that the shape and size of the connecting groove 12 are adapted to the connecting part 333, allowing the connecting part 333 to fit perfectly within the connecting groove 12. When installing the mounting base 33, the operator can quickly locate the installation position using the connecting groove 12, improving installation efficiency. Furthermore, the design of the connecting groove 12 also improves installation accuracy, ensuring that the mounting base 33 is installed in the correct position. In addition, the connecting part 333 being embedded in the connecting groove 12 makes the bottom surface of the main body 1 appear flatter and simpler, enhancing the overall aesthetics of the product.

[0062] Please refer to Figure 3 and Figure 5 In some embodiments, the connecting part 333 has a protruding positioning part 3331 on the side facing the bottom wall of the connecting groove 12, and the bottom wall of the connecting groove 12 has a recessed positioning groove 121 adapted to the positioning part 3331. The positioning part 3331 is inserted into the positioning groove 121. The bottom wall of the positioning groove 121 has a connecting hole 1211, and the fastener 4 passes through the connecting part 333 and the positioning part 3331 to be threaded into the connecting hole 1211.

[0063] It can be understood that the interlocking fit between the positioning groove 121 and the positioning part 3331 ensures that when the mounting base 33 is assembled with the main body 1, the positioning part 3331 can be accurately inserted into the positioning groove 121, thereby achieving precise positioning of the mounting base 33 on the main body 1. At the same time, it can restrict the movement of the mounting base 33 in the horizontal direction and ensure the relative positional accuracy between the mounting base 33 and the main body 1.

[0064] To secure the mounting base 33 to the main body 1, a connecting hole 1211 is provided on the bottom of the positioning groove 121. The fastener 4 can pass through the connecting part 333 and the positioning part 3331 and connect to the positioning groove 121 to fix the mounting base 33. For example, the fastener 4 is a bolt. By passing the bolt through the connecting part 333 and the positioning part 3331 and tightening it in the positioning groove 121, it is ensured that the mounting base 33 will not loosen due to frequent extension and retraction of the pull rod 32, thus improving connection stability.

[0065] To further improve the connection stability between the tie rod assembly 3 and the main body 1, at least two mounting seats 33 are provided, and at least two mounting seats 33 are spaced apart along the axial direction of the sleeve 31.

[0066] This can be understood as the number of mounting seats 33 being 2, 3, or 4, etc. For example, the number of mounting seats 33 is 2. The two mounting seats 33 are spaced apart along the axial direction of the sleeve 31. Specifically, they are set at both ends of the sleeve 31. The two mounting seats 33 are located at both ends of the sleeve 31, providing two-point support for the sleeve 31. Compared with single-point support, this can better withstand various forces generated by the pull rod 32 during extension and retraction, including tension and pressure. The mounting seats 33 at both ends can effectively disperse the force, reducing the risk of deformation or damage to the sleeve 31 due to uneven force, improving the stability and reliability of the connection between the entire pull rod assembly 3 and the main body 1, and ensuring that the pull rod 32 can work normally during the movement of the portable energy storage power supply 100, and is less prone to failure. Of course, the above is only an example, and the specific number and arrangement can be determined according to actual needs. This utility model does not impose any limitations here.

[0067] Please refer to Figure 2 and Figure 4 In some embodiments, the pull rod assembly 3 further includes a handle 34, which is disposed at one end of the pull rod 32 and connected to the pull rod 32; wherein, the receiving groove 11 includes a first sub-receiving groove 112 and a second sub-receiving groove 113, the second sub-receiving groove 113 is located at one end of the first sub-receiving groove 112 and communicates with the first sub-receiving groove 112, the sleeve 31 is accommodated in the first sub-receiving groove 112, and the second sub-receiving groove 113 is used to accommodate the handle 34.

[0068] The main function of the handle 34 is to provide a grip for the user to easily pull the lever 32. As the part that the user directly contacts, the handle 34 can be made of engineering plastics. Engineering plastics possess good strength and corrosion resistance, can withstand impacts without easily being damaged, and extend the service life of the lever assembly 3. Furthermore, to improve the user's feel, the handle 34 can also be made of a soft material, such as rubber, which can reduce friction between the handle 34 and the user's skin, thus improving the user experience. Of course, the above is only an example; the specific material can be determined according to actual needs, and this utility model does not impose any limitations.

[0069] The first sub-receiving groove 112 is used to accommodate the sleeve 31, providing installation space for the sleeve 31 and also playing a certain role in positioning and protecting the sleeve 31. The second sub-receiving groove 113 is located at one end of the first sub-receiving groove 112 and is connected to it. Its function is to specifically accommodate the handle 34, so that the handle 34 can be stored in the second sub-receiving groove 113 when not in use. It is independent of and connected to the storage space of the sleeve 31, forming an integrated storage structure, making the pull rod assembly 3 more compact when not in use.

[0070] In this embodiment, the second sub-receiving slot 113 extends through the front surface of the portable energy storage power supply 100. When the handle 34 is placed in the second sub-receiving slot 113, the second sub-receiving slot 113 has reserved space for the user's hand to reach in and grip the handle 34.

[0071] Please refer to Figure 6 To facilitate close-range adjustments during daily use of the portable power bank 100, two handles 5 are provided on the top of the main body 1, positioned opposite each other on the front and rear sides. In scenarios where the lever 32 is unsuitable, such as in confined spaces or short-distance transport, the handles 5 allow users to more easily carry or move the device. The user's hands can naturally grip the handles 5 located on the front and rear sides of the top, making it easier to apply force for transport or position adjustment, thus increasing the flexibility of use.

[0072] Please refer to Figure 1 In some embodiments, the front surface of the main body 1 is provided with a control panel 6. Specifically, the front surface is provided with a display screen and multiple charging ports. The display screen can display information such as the power level and temperature of the portable energy storage power supply 100, and the charging ports include DC ports, AC ports, and USB ports, providing users with a variety of interface types and improving the versatility of the portable energy storage power supply 100.

[0073] The above are only some or preferred embodiments of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the contents of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
