Description

Technical Field

[0001] This utility model relates to the field of mobile energy storage power technology, specifically to a portable mobile energy storage power supply. Background Technology

[0002] With the increasing demand for electricity in outdoor operations and emergency rescue scenarios, the application of portable mobile energy storage power supplies is becoming increasingly widespread. While existing similar products possess basic portability, they still have significant shortcomings:

[0003] In terms of mobility, traditional energy storage power supplies mostly adopt fixed wheel structures or simple lever designs, which are only suitable for flat, hard surfaces. When faced with complex terrain, the wheels are prone to getting stuck or jammed, requiring additional manpower for transport and severely impacting efficiency. For example, in outdoor rescue scenarios, rescuers often need to carry energy storage devices across rugged terrain, and the inconvenience of existing products may delay rescue efforts.

[0004] Regarding stability, existing products are typically placed directly on the ground upon arrival. When encountering uneven ground, slopes, or waterlogged areas, additional blocks, supports, or other auxiliary tools are required for leveling or raising, which is cumbersome and increases the burden of carrying them. Furthermore, while some improved products are equipped with adjustable feet, they generally suffer from complex structures and inconvenient operation. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a portable mobile energy storage power supply, which solves the technical problems of existing mobile energy storage power supplies being unable to travel on complex road surfaces and being inconvenient to provide stable support.

[0010] The movable rod has one end hinged to the fixed rod and the other end extending to the outside of the power supply box. The movable rod can swing vertically along the hinge position with the fixed rod so that the movable rod is perpendicular to the fixed rod. A support rod is slidably provided inside the movable rod along the axial direction. After the movable rod is in a position perpendicular to the fixed rod, the support rod can slide out of the movable rod and support the power supply box.

[0011] Optionally, the fixed rod has an axially oriented slot inside. After the movable rod swings to be parallel and aligned with the fixed rod, the support rod can slide into the slot to connect the fixed rod and the movable rod.

[0017] An adjusting screw is arranged along the length of the slide rail, and the adjusting screw passes through the threaded hole and is threadedly connected to the threaded hole. The adjusting screw is used to adjust the position of the wheel assembly at the bottom of the power supply box. One end of the adjusting screw is an adjusting end, and the other end of the adjusting screw is provided with a limit protrusion.

[0018] A connecting seat is disposed on the sliding seat. The connecting seat has a limiting groove with the opening of the limiting groove facing the fixed plate. The limiting protrusion is limitedly connected to the limiting groove and is rotatably connected to the limiting groove.

[0019] Optionally, the wheel assembly includes:

[0020] A rotating shaft is rotatably mounted on the sliding seat, and the rotating shaft can reciprocate along the slide rail following the sliding seat.

[0021] The device has two wheels, which are respectively disposed at both ends of the rotating shaft. The wheels are used to support the movement of the power supply box and also to cooperate with the support rod to support the power supply box.

[0022] Optionally, the wheel portion includes:

[0023] The mounting plate has its center rotatably mounted on the rotating shaft, and the mounting plate has at least two mounting positions.

[0024] The wheel has a plurality of wheels, each of which is rotatably mounted on one of the mounting positions.

[0025] Optionally, both ends of the slide rail are provided with stops to prevent the sliding seat from sliding off the slide rail.

[0026] Optionally, a handle is provided on the side wall of the power supply enclosure.

[0027] The beneficial effects of the embodiments of this utility model are as follows:

[0028] In this invention, when the energy storage power supply needs to be moved, the movable rod is parallel to the fixed rod. At this time, the support rod is inserted into the fixed rod. Under the action of the support rod, the movable rod and the fixed rod form a tight, integrated pull rod structure, facilitating the movement of the power supply box. After reaching the destination, the movable rod is vertically swung along the hinge position until it is perpendicular to the fixed rod. Then, the support rod is slid out of the movable rod. By simply adjusting the extension length of the support rod, the height of the mobile energy storage power supply above the ground can be adjusted. At this point, the support rod rests on the ground, thus stably supporting the power supply box.

[0029] By using a deflectable movable rod and a support rod that can extend from the movable rod, the mobile needs of the energy storage power supply are met, and the power supply box can be quickly and stably supported after reaching the destination without relying on additional auxiliary tools, thus solving the problem of cumbersome operation in terms of support stability of existing products.

[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] like Figures 1-7 As shown, this invention illustrates a portable mobile energy storage power supply according to one embodiment. The portable mobile energy storage power supply mainly consists of a power supply housing 1 and a pull rod assembly 2. A fixed rod 21 in the pull rod assembly 2 is securely mounted on the bottom surface of the power supply housing 1; one end of a movable rod 22 is hinged to the fixed rod 21, and the other end extends to the outside of the power supply housing 1. The movable rod 22 has an axially sliding support rod 23 inside, and the movable rod 22 can swing vertically around the hinge point with the fixed rod 21, reaching a position perpendicular to the fixed rod 21.

[0046] For example, such as Figure 1 and Figure 2 As shown, when the portable energy storage power supply needs to be moved, the movable rod 22 is parallel to the fixed rod 21. At this time, the support rod 23 is inserted into the fixed rod 21. Under the action of the support rod 23, the movable rod 22 and the fixed rod 21 form a tight, integrated pull rod structure, which facilitates the movement of the power supply box 1. It should be noted that at this time, the entire portable energy storage power supply looks like a pull-along suitcase. After reaching the destination, the movable rod 22 is swung vertically along the hinge position until it is perpendicular to the fixed rod 21. Then, the support rod 23 is slid out of the movable rod 22. By simply adjusting the extension length of the support rod 23, the height of the portable energy storage power supply above the ground can be adjusted. At this time, the support rod 23 is supported on the ground, thus stably supporting the power supply box 1.

[0047] By incorporating a deflectable movable rod 22 and a support rod 23 extending from it, the mobility requirements of the energy storage power supply are met. Upon arrival at its destination, the power supply unit 1 can be quickly and stably supported without the need for additional auxiliary tools, thus resolving the cumbersome operational issues related to stability in existing products. Furthermore, this portable power supply possesses the high-power charging and discharging characteristics of a supercapacitor, enabling fast charging and high discharge power, meeting the power needs of 380V industrial welding machines, argon arc welding machines, and 380V emergency rescue equipment.

[0048] Specifically, this power bank utilizes supercapacitor technology. Leveraging the unique energy storage mechanism and physical characteristics of supercapacitors, it achieves highly efficient and stable high-power charging and discharging performance. It's important to note that supercapacitors, also known as double-layer capacitors, differ from traditional batteries that rely on chemical reactions for energy storage. They store energy based on the electrostatic adsorption effect at the electrode-electrolyte interface, offering significant advantages such as fast charging and discharging speeds, long cycle life, and high power density. During charging, this power bank can rapidly accumulate energy in minutes or even less, achieving several times the charging efficiency of traditional lithium batteries and significantly reducing waiting time. During discharging, its ability to instantly release large currents is particularly outstanding, enabling a continuous and stable output of high-power energy. This easily powers specialized equipment with stringent power requirements, such as 380V industrial welding machines and argon arc welding machines, ensuring the precision and continuity of welding operations.

[0049] Facing the power demands of 380V emergency rescue equipment in disaster relief scenarios, this portable power bank also performs exceptionally well, providing strong and stable power support for critical equipment such as life detectors and hydraulic demolition tools, ensuring the efficient progress of rescue operations. Furthermore, the supercapacitor features a wide operating temperature range and strong environmental adaptability, maintaining stable performance even in extreme low or high temperature environments. This allows it to meet diverse power needs in different regions and under different working conditions, greatly expanding the application scenarios and practical value of portable power banks.

[0050] In some examples, the fixed rod 21 has an axially oriented slot 210 inside. After the movable rod 22 swings to be parallel and aligned with the fixed rod 21, the support rod 23 can slide into the slot 210 to connect the fixed rod 21 and the movable rod 22. The size of the slot 210 is adapted to the support rod 23.

[0051] For example, such as Figure 1 As shown, when the movable rod 22 swings to be parallel and aligned with the fixed rod 21, the support rod 23 is slid into the slot 210. At this time, the fixed rod 21, the movable rod 22, and the support rod 23 are connected to each other, forming a stable pull rod structure, which facilitates the movement of the power supply box 1. This connection method makes the pull rod assembly 2 more stable in the moving state, avoids wobbling between the movable rod 22 and the fixed rod 21, improves the stability and reliability during the movement process, and the connection operation is simple and convenient.

[0052] In some examples, the side wall of the movable rod 22 is provided with a groove 220 that communicates with the interior, and a carrying plate 3 is fixedly installed on the support rod 23. The carrying plate 3 is slidably engaged with the groove 220 and is slidably disposed in the groove 220. The carrying plate 3 is used to push and pull the support rod 23 to slide along the interior of the movable rod 22.

[0053] For example, such as Figure 2 As shown, when the support rod 23 needs to be slidable, the operator pushes or pulls the carrying plate 3. The sliding of the carrying plate 3 within the slide groove 220 causes the support rod 23 to slide along the inside of the movable rod 22, thus extending or retracting the support rod 23. The carrying plate 3 allows the operator to control the sliding of the support rod 23 more conveniently and effortlessly, making the operation more user-friendly, improving ease of use, and reducing operational difficulty.

[0054] In some examples, the outer wall of the movable rod 22 has several through holes 221 spaced axially. At least one locking bolt is installed on the movable rod 22, and the locking bolt is threaded into the through hole 221, with the end of the locking bolt abutting against the support rod 23. It should be noted that wing bolts can be used to facilitate tightening the locking bolts.

[0055] For example, such as Figure 3 and Figure 4 As shown, after the support rod 23 slides out of the movable rod 22 to a suitable position, the locking bolt is screwed into the corresponding through hole 221, so that the end of the locking bolt abuts against the support rod 23, thereby fixing the position of the support rod 23. When it is necessary to adjust the position of the support rod 23, loosen the locking bolt, slide the support rod 23 to the new position, and then tighten the locking bolt again to fix it. Through the cooperation of the locking bolt and the through hole 221, the position of the support rod 23 can be flexibly adjusted and fixed according to different usage scenarios and needs, ensuring the stable support of the power supply box 1 and improving the adaptability and stability of the product.

[0056] In some examples, a slide rail 4 is installed at the bottom of the power supply housing 1, a slide seat 5 is slidably mounted on the slide rail 4, and a wheel assembly is mounted on the slide seat 5. The wheel assembly can reciprocate along the slide rail 4 following the slide seat 5.

[0057] For example, such as Figure 5As shown, when moving the power supply box 1, the wheel assembly slides along the slide rail 4 following the sliding seat 5, facilitating adjustment of the wheel assembly's position in different terrains to adapt to terrain changes. When stable placement of the power supply box 1 is required, the wheel assembly can be slid to a suitable position and used in conjunction with other support structures for stable support. Specifically, with the support rod 23, the power supply box 1 is placed horizontally. If it is necessary to place the power supply box 1 vertically, the wheel assembly needs to be retracted so that the power supply box 1 is not affected by the wheel assembly when placed vertically.

[0058] The cooperation between the slide rail 4, the sliding seat 5, and the wheel assembly allows the position of the wheel assembly to be flexibly adjusted, enhancing the mobility of the power supply in complex terrain. Compared with a fixed wheel structure, it can better cope with different road conditions and reduce the possibility of the rollers getting stuck or jammed.

[0059] In some examples, the slide rail 4 consists of a fixed plate 6, an adjusting screw 7, and a connecting seat 51. The fixed plate 6 is located at the end of the slide rail 4 away from the sliding seat 5, and has a threaded hole 61. The adjusting screw 7 is arranged along the length of the slide rail 4, passes through the threaded hole 61, and is threadedly connected to the threaded hole 61. One end of the adjusting screw 7 is an adjustment end 71 for easy operation, and the other end has a limiting protrusion 72. The connecting seat 51 is mounted on the sliding seat 5 and has a limiting groove 510 with its opening facing the fixed plate 6. The limiting protrusion 72 is limited and rotatably connected to the limiting groove 510.

[0060] For example, such as Figure 6 and Figure 7 As shown, by rotating the adjusting end 71 of the adjusting screw 7, since the adjusting screw 7 is threadedly connected to the threaded hole 61 on the fixed plate 6, the adjusting screw 7 will move axially, driving the sliding seat 5 and the wheel assembly to move on the slide rail 4. The limiting protrusion 72 rotates within the limiting slot 510, ensuring the stable movement of the sliding seat 5, thereby realizing the adjustment of the position of the wheel assembly at the bottom of the power supply box 1. The structure of the limiting protrusion 72 and the limiting slot 510 allows for convenient and quick adjustment of the position of the wheel assembly to adapt to different terrains and usage requirements. The operation is simple, and the adjustment process is stable and reliable, reducing the difficulty of operation compared to some complex adjustment structures.

[0061] In some examples, the wheel assembly consists of a shaft 901 and two wheel sections 90. The shaft 901 is rotatably mounted on the sliding seat 5 and can move along the slide rail 4 with the sliding seat 5. The two wheel sections 90 are respectively mounted at both ends of the shaft 901. The wheel sections 90 can both support the movement of the power supply box 1 and cooperate with the support rod 23 to provide stable support for the power supply box 1. In the supported state, the stability of the support can be increased by locking the wheels.

[0062] For example, such as Figure 6As shown, when moving the power supply box 1, the wheel section 90 rotates around the pivot 901 to move the power supply. After reaching the destination, by adjusting the position of the wheel section 90 and cooperating with the support rod 23, the power supply box 1 is stably supported on the ground. The wheel assembly makes the power supply more stable during movement and support, and by cooperating with the support rod 23, it can better adapt to different terrains, solving the problem of inconvenient movement and support of existing products in complex terrains.

[0063] In some examples, the wheel section 90 consists of a mounting plate 902 and several wheels 903. The mounting plate 902 is rotatably mounted on a pivot 901 at its center, and the mounting plate 902 has at least two mounting positions 9021, with each wheel 903 rotatably mounted on one mounting position 9021. Specifically, the mounting plate 902 has three mounting positions 9021, which are arranged circumferentially. On complex road surfaces, the rotation of the mounting plate 902 allows different wheels 903 to contact the ground.

[0064] For example, such as Figure 6 As shown, during movement, the wheels 903 rotate around the mounting position 9021. Multiple wheels 903 work together to improve the power supply's mobility on different terrains. During support, the angle of the mounting plate 902 can be adjusted according to ground conditions to ensure better contact between the wheels 903 and the ground, working in conjunction with the support rod 23 to stably support the power supply housing 1. The rotatable structure of the multiple wheels 903 and the mounting plate 902 enhances the power supply's mobility and support stability in complex terrains. Compared to a single wheel 903, it can better distribute pressure, improving mobility and stability.

[0065] In some examples, both ends of the slide rail 4 are provided with stops 8 to prevent the slide seat 5 from sliding off the slide rail 4.

[0066] For example, such as Figure 6 As shown, when the sliding seat 5 slides on the slide rail 4, if the sliding seat 5 moves to the end of the slide rail 4, the stop block 8 will prevent the sliding seat 5 from continuing to move, thus preventing the sliding seat 5 from sliding off the slide rail 4. The stop block 8 effectively prevents the sliding seat 5 from sliding off the slide rail 4, ensuring the safety and reliability of the wheel assembly sliding on the slide rail 4, and avoiding equipment damage or inconvenience caused by the sliding seat 5 sliding off.

[0067] In some examples, a handle 10 is provided on the side wall of the power supply housing 1.

[0068] For example, such as Figure 5As shown, the shape and position of the handle 10 are designed for easy gripping by the operator. When moving the power supply box 1, the operator can easily push or pull the power supply box 1 by gripping the handle 10. The design of the handle 10 provides the operator with a more convenient point of force application, making the operation of the power supply box 1 easier and more convenient.
