Description

Technical Field

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

[0002] Portable energy storage power supplies are key equipment for emergency power supply and outdoor power use, and portability is one of the core requirements of users. Currently, most portable energy storage power supplies on the market are only lifted and put down by a handle integrated into the shell. Although this design can meet the needs of short-distance and temporary movement, it has obvious limitations in practical applications.

[0003] When users need to move the energy storage power supply to a distant location (such as moving it from one side of an outdoor campsite to the other) or frequently adjust the placement of the device, relying solely on lifting and placing it by the handle requires users to continuously apply upward gripping force to keep the device suspended in the air. This not only easily leads to hand fatigue but also significantly prolongs the time spent on moving the device. This time-consuming and laborious problem is even more prominent for energy storage power supply products with larger capacity and higher weight, seriously affecting the user experience and failing to fully adapt to the efficient mobility needs in diverse scenarios.

[0023] Reference Figures 1-3 This embodiment provides a mobile energy storage power supply, including a housing assembly, a battery pack 2, a circuit control device 3, and a mobile device 4; The housing assembly includes a base plate assembly 10 and an outer shell assembly disposed on the base plate assembly 10; The battery pack 2 is disposed on the base plate assembly 10, the circuit control device 3 is disposed at the end of the battery pack 2 away from the base plate assembly 10, and the battery pack 2 and the circuit control device 3 are respectively located inside the outer casing assembly; The moving device 4 includes a rotating shaft 40 and a plurality of rollers 41. The rotating shaft 40 passes through and is fixedly connected to the base plate assembly 10, and the rollers 41 are rotatably connected to the rotating shaft 40.

[0024] In the above embodiment, the mobile energy storage power supply includes a housing assembly, a battery pack 2, a circuit control device 3, and a mobility device 4. The mobile energy storage power supply is 3600W. The housing assembly, serving as the supporting foundation of the overall structure, is composed of a base plate assembly 10 and an outer shell assembly mounted on it, providing an installation platform and protection for internal functional components. The battery pack 2 is fixed to the base plate assembly 10 and is the energy storage unit of the device. The circuit control device 3 is located above the battery pack 2, at the end furthest from the base plate assembly 10, and is electrically connected to the battery pack 2, used to manage the charging and discharging process and power output. Both the battery pack 2 and the circuit control device 3 are enclosed by the outer shell assembly, forming a safe and enclosed internal space. The mobility device 4 is a key structure for achieving portability, mainly including a rotating shaft 40 and multiple rollers 41. The rotating shaft 40 passes laterally through the base plate assembly 10 and is firmly fixed thereto, forming a stable load-bearing structure. The rollers 41 are rotatably connected to both ends of the rotating shaft 40 via bearings or a rotating shaft structure, preferably two rollers, located on the left and right sides of the base plate assembly 10 respectively. When the device needs to be moved, the user can lift the rear of the housing assembly with external force, so that the roller 41 contacts the ground. At this time, the roller 41 serves as the rolling fulcrum, and the entire device can be pushed or pulled to achieve smooth rolling displacement, thereby replacing the traditional method of relying entirely on lifting and carrying. Therefore, by providing a through-and-fixed rotating shaft 40 and a rotatably connected roller 41 on the base plate assembly 10, the mobile energy storage power supply can be moved by rolling with the help of the roller 41, replacing the traditional method of lifting and placing only by the handle 113. When moving long distances or frequently, there is no need to continuously exert force to hold it, which greatly reduces hand fatigue. At the same time, the rolling movement method shortens the operation time, improves the movement efficiency, effectively solves the problem of the original method being time-consuming and laborious, and better meets the needs of high efficiency and portability in diverse scenarios.

[0025] Reference Figures 1-3 In one embodiment, the base plate assembly 10 includes a base plate body 101, the battery pack 2 and the outer shell assembly are respectively disposed on the base plate body 101, the base plate body 101 is provided with a plurality of clearance grooves 102, the rotating shaft 40 is disposed on the base plate body 101, and the roller 41 is located in the clearance groove 102 and connected to the rotating shaft 40.

[0026] In the above embodiment, the bottom plate assembly 10 includes a bottom plate body 101, which is used to support upper equipment and integrate mobile functional components. Two avoiding grooves 102 are symmetrically provided on the left and right sides of the bottom plate body 101. These avoiding grooves 102 are recessed to a certain depth from the side edges of the bottom plate body 101 to form an accommodation space, whose size and position precisely match the installation requirements of the rollers 41; the rotating shaft 40 is a rigid rod-shaped structure that transversely penetrates the bottom plate body 101 and passes through the avoiding grooves 102 on both sides. Both ends of the rotating shaft 40 extend out of the bottom plate body 101 and are fixedly connected with the bottom plate body 101. The rollers 41 are cylindrical or tire-shaped structures, with a total number of two, which are respectively installed at both ends of the rotating shaft 40 and can freely rotate relative to the rotating shaft 40 through a bearing or rotating shaft structure. Each roller 41 is located inside the corresponding avoiding groove 102, and its outer edge portion protrudes from the bottom opening of the avoiding groove 102, and can contact the ground when the device is tilted. By providing the avoiding grooves 102 on the bottom plate body 101 and integrating the rotating shaft 40 and the rollers 41, embedded installation of the rollers 41 is realized, which not only ensures the smooth rotation of the rollers 41, but also enhances the structural stability and protection, and effectively improves the movement convenience.

[0027] Reference Figures 1-3 , in an embodiment, the bottom plate assembly 10 further includes a plurality of fixing blocks 103, the fixing blocks 103 are disposed on a side of the bottom plate body 101 away from the battery pack 2, and a height difference is formed between the bottom plane of the fixing blocks 103 and the bottom plane of the rollers 41.

[0028] In the above embodiment, the bottom plate assembly 10 further includes a plurality of fixing blocks 103. A plurality of fixing blocks 103 are provided on a side of the bottom plate body 101 away from the upper equipment, that is, on the bottom surface. The fixing blocks 103 are rigid protruding structures, which are directly formed or fixedly connected to the bottom surface of the bottom plate body 101. The number of the fixing blocks 103 is three, and they are arranged in a "pin-shaped" layout, that is, two fixing blocks 103 are arranged side by side on both sides of the rear part of the bottom plate body 101, and another fixing block 103 is located in the center of the front part. The bottom planes of all the fixing blocks 103 are on the same horizontal plane. In addition, there is a clear height difference between the bottom plane of the fixing blocks 103 and the bottom plane of the rollers 41, that is, the bottom surface of the fixing blocks 103 is lower than the lowest point of the rollers 41. When the bottom plate body 101 is placed flat on a horizontal ground, the fixing blocks 103 contact the ground first and bear all vertical loads. At this time, the rollers 41 are suspended due to their higher positions, and a preset gap is maintained between the bottom of the rollers 41 and the ground. This height difference design ensures that the device will not accidentally slide or roll due to the contact between the rollers 41 and the ground in a static state, and improves the stability and safety of placement.

[0029] Reference Figures 1-3In one embodiment, the base plate assembly 10 further includes a pull-out component 104, which includes a pull-out fixing part 1040 and a handle body 1041. The base plate body 101 has a receiving groove 105 on the side away from the battery pack 2. The pull-out fixing part 1040 is located in the receiving groove 105 and is fixedly connected to the base plate body 101. The handle body 1041 is telescopically slidably connected to the pull-out fixing part 1040.

[0030] In the above embodiment, the base plate assembly 10 further includes a pull-out component 104. The pull-out component 104 includes a pull-out fixing part 1040 and a handle body 1041. The base plate body 101 has a receiving groove 105 on the side away from the battery pack 2. The pull-out fixing part 1040 is embedded and firmly connected to the receiving groove 105. It has a sliding guide rail or limiting channel inside to guide and constrain the movement trajectory of the handle body 1041. The handle body 1041 is a telescopic rod-shaped or frame-shaped structure. One end of it is connected to the pull-out fixing part 1040 in a sliding fit manner. It can be pulled out or retracted in a straight line from the pull-out fixing part 1040 under the action of external force. The handle body 1041 and the pull-out fixing part 1040 form a telescopic sliding connection, allowing the handle body 1041 to be completely stored in the pull-out fixing part 1040 and the receiving groove 105 when not in use. When the device needs to be moved, the user pulls the handle body 1041 out of the pull-out fixing part 1040 to a suitable length, forming an easy-to-grip operating handle. At this time, by applying force to the handle body 1041 and tilting the entire base plate body 101 upward, the roller 41 contacts the ground and bears the main support force. Then, by applying a horizontal pulling force through the handle body 1041, the entire device can be driven to roll around the roller 41 as the fulcrum. This achieves a hidden design for the mobility assistance function, making the device move as smoothly and effortlessly as a suitcase, improving operational convenience and user comfort.

[0031] Reference Figures 1-3 In one embodiment, the base plate assembly 10 further includes a plurality of first reinforcing ribs 106, which are disposed on the side of the base plate body 101 near the battery pack 2, and the plurality of first reinforcing ribs 106 are arranged in a crisscross pattern.

[0032] In the above embodiments, the base plate assembly 10 also includes a plurality of first reinforcing ribs 106. These first reinforcing ribs 106 are raised rib-like structures and are integrally formed with the base plate body 101. The plurality of first reinforcing ribs 106 are arranged according to a specific layout rule. Specifically, they are arranged in a vertical and horizontal crisscross pattern along the length and width directions of the base plate body 101 to form a grid-like or grid-like structure. This arrangement means that there are multiple parallel first reinforcing ribs 106 distributed along the length direction of the base plate body 101, and multiple first reinforcing ribs 106 that intersect perpendicularly with it along the width direction. The two intersect each other to form multiple rectangular or square reinforcing units. This structure not only enhances the bending stiffness of the base plate body 101 in the longitudinal and transverse directions, but also effectively improves the overall torsional performance and load-bearing capacity.

[0033] Reference Figures 1-3 In one embodiment, the housing assembly includes a housing body, which includes a front shell 1101, a rear shell 1102, a left shell 1103, and a right shell 1104 fixedly connected to the base plate body 101. The front shell 1101 and the rear shell 1102, which are arranged opposite to each other, are respectively connected to the left shell 1103 and the right shell 1104, and the front shell 1101, the rear shell 1102, the left shell 1103, the right shell 1104, and the base plate body 101 together form a first accommodating space, and the battery pack 2 is located in the first accommodating space.

[0034] In the above embodiment, the outer shell assembly includes an outer shell body, which is composed of a front shell 1101, a rear shell 1102, a left shell 1103, and a right shell 1104, forming an enclosed frame structure. The front shell 1101 and the rear shell 1102 are two shell components arranged opposite each other, located at the front and rear ends of the outer shell body, respectively. The left shell 1103 and the right shell 1104 are also two shell components arranged opposite each other, located on the left and right sides of the outer shell body, respectively. The two sides of the front shell 1101 and the rear shell 1102 are fixedly connected to the corresponding sides of the left shell 1103 and the right shell 1104, respectively. The connection method can be screw fastening, snap-fit ​​engagement, or welding, etc. At the same time, the bottom edges of the front shell 1101, the rear shell 1102, the left shell 1103, and the right shell 1104 are all fixedly connected to the base plate body 101, so that the entire outer shell body is firmly installed on the base plate body 101.

[0035] Through the above connection method, the front shell 1101, rear shell 1102, left side shell 1103, right side shell 1104 and the bottom plate body 101 together enclose a closed or semi-closed internal space, called the first accommodating space. The battery pack 2 is located in the first accommodating space. This space is located inside the outer shell body and is surrounded by five sides (front, rear, left, right and bottom). The front shell 1101 and rear shell 1102 are not only connected to the side shells and the bottom plate body 101, but also directly connected to the internal equipment, which effectively improves the overall strength and sealing of the outer shell, provides a safe and stable installation space for the internal equipment, and enhances the protection capability.

[0036] Reference Figures 1-5 In one embodiment, the outer shell body further includes a plurality of second reinforcing ribs 1105 and a plurality of third reinforcing ribs 1106. The second reinforcing ribs 1105 are arranged in an array on the left shell 1103, and the third reinforcing ribs 1106 are arranged in an array on the right shell 1104, and the second reinforcing ribs 1105 and the third reinforcing ribs 1106 are arranged symmetrically to each other.

[0037] In the above embodiments, the outer shell body further includes a plurality of second reinforcing ribs 1105 and a plurality of third reinforcing ribs 1106. A plurality of second reinforcing ribs 1105 are provided on the inner surface of the left shell 1103, forming an integrally molded protrusion structure that is arranged in a regular array along the shell surface. Similarly, a plurality of third reinforcing ribs 1106 are provided at corresponding positions on the right shell 1104, identical to the second reinforcing ribs 1105 and also arranged in an array. The second reinforcing ribs 1105 and the third reinforcing ribs 1106 are arranged symmetrically in the overall structure, that is, when... When the outer shell is folded along the central axis of the power supply, the positions and shapes of the second reinforcing rib 1105 and the third reinforcing rib 1106 completely overlap, forming a mirror symmetry relationship. All the second reinforcing ribs 1105 and the third reinforcing ribs 1106 adopt a regular hexagonal honeycomb structure, that is, each reinforcing rib unit is a regular hexagon. Multiple hexagonal units are adjacent to each other, share sidewalls, and are closely arranged to form a honeycomb-like geometric shape. This not only improves the structural strength of the left and right shells, but also enhances the overall stability and torsional resistance of the outer shell, providing more reliable external protection for the equipment.

[0038] Reference Figures 1-7 In one embodiment, the housing assembly further includes a top shell 111 connected to the housing body, and a second receiving space is formed within the top shell 111. The circuit control device 3 is disposed on the battery pack 2 and located within the second receiving space.

[0039] In the above embodiments, the outer casing assembly also includes a top shell 111, the shape of which matches the top opening of the outer casing body, for sealing the upper area of ​​the outer casing body. The top shell 111 is installed on the top of the outer casing body by a fixed connection method, such as screw fastening, snap-fit, or adhesive bonding. A closed or semi-closed space area is formed inside the top shell 111, called the second accommodating space. This space is enclosed by the inner wall of the top shell 111 and is located in the upper area formed after the top shell 111 is connected to the outer casing body. The circuit control device 3 is set on the battery pack 2 and is located in the second accommodating space. By setting the top shell 111 and forming the second accommodating space inside it, the functional area of ​​the outer casing assembly is expanded, the sealing and protection capabilities are improved, modular layout is facilitated, and the overall structural stability and safety are enhanced.

[0040] Reference Figures 1-7 In one embodiment, the top shell 111 is provided with a plurality of grip grooves 112 on the side away from the circuit control device 3, and a handle 113 is provided in the grip grooves 112.

[0041] In the above embodiment, a plurality of grip grooves 112 are provided on the outer surface of the top shell 111. The grip grooves 112 are recessed structures, directly formed on the outer surface of the top shell 111, forming a space that is easy for the hand to grip. There are two grip grooves 112, which are respectively arranged at both ends of the outer surface of the top shell 111, near the edges in the front-rear direction, forming a symmetrical layout. A handle 113 is provided inside each grip groove 112. The handle 113 is a rigid rod-shaped or arc-shaped structure, fixedly connected between the two side walls of the grip groove 112, spanning the groove, forming a grip point where force can be applied. The user can grip the handle 113. By gripping the handle 113, an upward or horizontal force is applied to lift or move the device. On the inner surface of the top shell 111, i.e., the top plate area inside the top shell 111, multiple fourth reinforcing ribs are provided. These fourth reinforcing ribs are protruding structures integrally formed with the top shell 111 and distributed along the inner surface. The fourth reinforcing ribs have a regular hexagonal honeycomb structure, with multiple regular hexagonal units closely arranged and sharing sidewalls to form a high-strength grid layout. This honeycomb structure has excellent compressive and deformation resistance, can effectively disperse external forces, and improve the overall rigidity and load-bearing capacity of the top shell 111.

[0042] Reference Figures 1-7 In one embodiment, the circuit control device 3 includes a circuit control board 30 and a heat sink 31. The circuit control board 30 is connected to the battery pack 2, and the heat sink 31 is disposed on the circuit control board 30. The top shell 111 has a plurality of heat dissipation holes 32 on its side, and the heat dissipation holes 32 are arranged corresponding to the cooling fan of the heat sink 31.

[0043] In the above embodiments, the circuit control device 3 includes a circuit control board 30 and a heat sink 31. The circuit control board 30 is a core electronic component, using an AC board, for converting, regulating, and controlling alternating current. It is electrically connected and fixedly installed above the battery pack 2, establishing an electrical path with the battery pack 2, receiving electrical energy, processing it, and then outputting it. The heat sink 31 is a housing structure with a accommodating space, placed on top of the circuit control board 30, covering its surface or a partial area, for protecting the circuit control board 30 and integrating heat dissipation. A cooling fan is installed inside or outside the heat sink 31. This fan is a small active cooling device that generates directional airflow after being powered on to accelerate heat dissipation. In addition, this power supply adopts an LLC resonant topology and advanced power devices. The LLC topology utilizes soft-switching technology to create conditions for the switching transistor to turn on when the voltage is zero (ZVS). Alternatively, it can switch off when the current is zero (ZCS), which virtually eliminates switching losses and EMI, greatly reducing switching losses. Combined with digital control algorithms (such as dual-loop control), it achieves high-efficiency bidirectional energy conversion. The top shell 111 has multiple heat dissipation holes 32 on its sides. These holes 32 are through-holes penetrating the sidewalls of the top shell 111, distributed near the left and right side panels. Their positions precisely correspond to the cooling fans of the heat sink 31, meaning the fan's exhaust direction faces the heat dissipation holes 32, forming a continuous airflow channel. When the cooling fan is running, airflow is drawn in from around the circuit control board 30, passes through the interior of the heat sink 31, and is then exhausted to the external environment through the heat dissipation holes 32, effectively dissipating internal heat. The corresponding arrangement of the heat dissipation holes 32 and the cooling fan ensures unobstructed airflow and maximizes heat dissipation efficiency, preventing heat accumulation inside the top shell 111, effectively reducing internal temperature, and improving the stability and safety of the circuit system.
