Description

Technical Field

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

[0002] In the field of portable energy storage power supplies, in order to achieve a balance between device portability and energy storage function, the battery pack, as the core energy storage component, has its installation structure design that directly affects the overall performance of the product and the user experience. Currently, the mainstream portable energy storage power supplies in the industry generally adopt the structure of directly installing the battery pack on the bottom plate of the casing. Although this installation method can simplify the initial assembly process, it has significant drawbacks in practical applications.

[0003] On the one hand, battery packs continuously generate heat during charging and discharging. When directly mounted to the base plate, this heat tends to accumulate between the battery pack and the base plate, making it difficult for the heat to dissipate quickly through the casing. Over time, this can lead to excessively high local temperatures in the battery pack, reducing energy conversion efficiency, accelerating battery aging, shortening battery lifespan, and even posing a risk of thermal runaway, thus threatening the safety of the device. On the other hand, portable energy storage power supplies need to be moved frequently and are susceptible to vibration, impact, and other external forces during handling and carrying. The structure of the battery pack being directly fixed to the base plate lacks effective buffering protection, allowing external forces to be directly transmitted to the internal cells, potentially causing cell deformation, tab breakage, and other damage, leading to battery pack failure. This affects the reliability and lifespan of the portable energy storage power supply, failing to meet users' needs for long-term stable use of the device. Utility Model Content

[0023] Reference Figures 1-3This embodiment provides a portable energy storage power supply, including a support component 1 and a housing assembly 2; The housing assembly 2 includes an outer shell assembly 20, a base plate 21, and a reinforcing rib assembly 22. The outer shell assembly 20 and the support assembly 1 are respectively disposed on the base plate 21, and the support assembly 1 is located inside the outer shell assembly 20. The support assembly 1 is used to install an electronic energy storage module. The reinforcing rib assembly 22 is disposed on the side of the base plate 21 near the support assembly 1, and the electronic energy storage module is in contact with the reinforcing rib assembly 22.

[0024] In the above embodiments, the portable energy storage power supply includes a support assembly 1 and a housing assembly 2. The support assembly 1 is a structural unit for supporting and fixing the electronic energy storage module. It is mounted on the base plate 21 and enclosed by the housing assembly 20, providing support and positioning. The housing assembly 2 is composed of the housing assembly 20, the base plate 21, and the reinforcing rib assembly 22, forming a closed or semi-closed space to protect internal functional components and prevent external environmental interference. The base plate 21 serves as the basic support platform for the entire device, located at the bottom of the equipment. It is used to install the housing assembly 20 and the support assembly 1 and to transfer loads to the ground or other supporting surfaces. The reinforcing rib assembly 22 is located on the side of the base plate 21 closest to the support assembly 1, i.e., on the inner upper surface area of ​​the base plate 21. Its main function is... This enhances the structural rigidity and deformation resistance of the base plate 21, improving overall load-bearing capacity. The electronic energy storage module is the core functional unit of the equipment, comprising a battery pack and a control circuit board. The battery pack is responsible for storing and releasing electrical energy, providing power output to external devices. The control circuit board manages the charging and discharging process of the battery pack, voltage regulation, overcurrent protection, and other electrical control functions, ensuring the safe and stable operation of the system. The electronic energy storage module is installed on the support assembly 1, with the bottom of the battery pack in direct contact with the top of the reinforcing rib assembly 22. This allows the weight of the battery pack to be transferred to the base plate 21 through the reinforcing rib assembly 22, forming an effective force transmission path, rather than the battery pack directly contacting the base plate 21. By placing the reinforcing rib assembly 22 on the side of the base plate 21 close to the electronic energy storage module and ensuring its contact, the reinforcing rib assembly 22 provides support and buffer, reducing the direct impact of external forces on the electronic energy storage module, lowering the risk of cell damage, and improving equipment reliability. Furthermore, the reinforcing rib assembly 22 increases the heat dissipation area, accelerating heat conduction and dissipation, preventing heat accumulation, improving efficiency, extending lifespan, reducing safety risks, and meeting the requirements for long-term stable use.

[0025] Reference Figures 1-3 In one embodiment, the reinforcing rib assembly 22 includes a plurality of first reinforcing ribs 220, which are arranged continuously on the base plate 21 and extend along the width direction of the base plate 21.

[0026] In the above embodiments, the reinforcing rib assembly 22 includes a plurality of first reinforcing ribs 220. Each first reinforcing rib 220 is a strip-shaped plate structure with enhanced support function. Its cross-section can be rectangular, trapezoidal, or T-shaped, and it has a certain height and thickness. The plurality of first reinforcing ribs 220 are arranged continuously on the base plate 21, meaning that all first reinforcing ribs 220 extend along the width direction of the base plate 21 (defined as the first direction) and are arranged sequentially. There are no gaps between adjacent first reinforcing ribs 220, forming a seamless splicing structure. This seamless splicing refers to the... The reinforcing ribs 220 are completely fused together or have no physical boundaries, thereby forming a reinforcing band that extends continuously along the width direction on the surface of the base plate 21. Multiple first reinforcing ribs 220 are arranged in parallel along this direction, and the length direction of each first reinforcing rib 220 is consistent with the width direction, covering the corresponding area of ​​the base plate 21. The first reinforcing ribs 220 and the base plate 21 are integrally formed or firmly connected. The continuous and seamless arrangement of the first reinforcing ribs 220 significantly improves the structural strength and rigidity of the base plate 21, effectively prevents deformation, and improves the overall stability and service life of the equipment.

[0027] Reference Figures 1-3 In one embodiment, the first reinforcing rib 220 includes a first rib 2201, a second rib 2202, and a plurality of third ribs 2203. The first rib 2201 and the second rib 2202 are disposed opposite to each other on the base plate 21, and the plurality of third ribs 2203 are spaced apart between the first rib 2201 and the second rib 2202 and connected to the base plate 21.

[0028] In the above embodiment, the first reinforcing rib 220 includes a first rib 2201, a second rib 2202, and a plurality of third ribs 2203. The first rib 2201 and the second rib 2202 are two main strip-shaped reinforcing plates, respectively arranged opposite each other along the edge region of the base plate 21, typically parallel to the width direction of the base plate 21. The plurality of third ribs 2203 are arranged between the first rib 2201 and the second rib 2202, along the spatial interval between them, forming a transverse or longitudinal connecting support. All third ribs 2203 are directly connected to the base plate 21 and fixed to the surface of the base plate 21 by an integral molding process. The first rib 2201 and the second rib 2202 are arranged opposite each other, meaning that they are symmetrical or parallel to each other in space, forming the two side boundaries of a frame structure. Multiple third ribs 2203 serve as intermediate support units, evenly distributed in the area between the two, and together with the first rib 2201 and the second rib 2202, they form a reinforced structure similar to a "ladder" or "grid". The first rib 2201, the second rib 2202 and the multiple third ribs 2203 are connected to the base plate 21 to form a stable three-dimensional support network, which significantly enhances the load-bearing capacity and vibration resistance of the base plate 21, making it suitable for energy storage devices that require high structural stability.

[0029] Reference Figures 1-3 In one embodiment, the first reinforcing rib 220 further includes a plurality of fourth ribs 2204, the third rib 2203 is a first arc-shaped structure recessed towards the base plate 21, the fourth ribs 2204 are disposed between adjacent third ribs 2203 and connected to the base plate 21, and the top plane of the fourth ribs 2204 is tangent to the arc surface of the third ribs 2203.

[0030] In the above embodiment, the first reinforcing rib 220 further includes multiple fourth ribs 2204. The third rib 2203 is an integrally recessed first arc-shaped structure facing towards the bottom plate 21, that is, the cross-section is a downwardly convex arc (similar to an inverted arch). Multiple third ribs 2203 form the main arc-shaped support unit. The fourth rib 2204 is a strip-shaped flat plate structure, which is set in the gap area between two adjacent third ribs 2203, and its bottom is directly connected to the bottom plate 21. The top plane of the fourth rib 2204 is tangential to the arc surface of the third rib 2203, which means that... The top of the fourth rib 2204 is in contact with the lowest point of the arc-shaped structure of the third rib 2203, and the two share a tangent at that point. That is, the height of the fourth rib 2204 is precisely set to be consistent with the height of the bottom of the arc surface of the third rib 2203, so that the lowest contact surfaces of all supporting components are on the same horizontal plane. The entire structure combines the arc-shaped compressive strength of the third rib 2203 with the planar support of the fourth rib 2204 to form a continuous and uniform load-bearing surface on the surface of the base plate 21, which enhances the stability and deformation resistance of the structure.

[0031] Reference Figures 1-3 In one embodiment, the reinforcing rib assembly 22 further includes a plurality of second reinforcing ribs 221, which are spaced apart on the side of the third rib 2203 away from the first rib 2201, and the second reinforcing ribs 221 are connected to the base plate 21.

[0032] In the above embodiment, the reinforcing rib assembly 22 further includes a plurality of second reinforcing ribs 221. The second reinforcing ribs 221 are strip-shaped plate structures, and their height is less than that of the fourth rib 2204, the first rib 2201, and the second rib 2202, indicating that it is a low-profile reinforcing structure. The plurality of second reinforcing ribs 221 are disposed on the side of the third rib 2203 away from the first rib 2201, that is, located in the outer edge region of the entire reinforcing structure, and are arranged perpendicularly to the outermost side of the third rib 2203, so that their radial extension direction is perpendicular to that of the third rib 2204. 3. The two reinforcing ribs are perpendicularly connected to form lateral support. All the second reinforcing ribs 221 are parallel to each other and evenly spaced along the same radial direction. That is, the spacing between two adjacent second reinforcing ribs 221 is the same. The reinforcing cross plate is set at both ends of the first reinforcing rib 220 and extends perpendicular to the direction of the second reinforcing rib 221. The multiple second reinforcing ribs 221 are connected at the ends to form a frame structure. This layout makes the second reinforcing ribs 221 and the reinforcing cross plate together form the outer grid-like reinforcement area, which not only improves the edge torsional resistance, but also prevents lateral deformation.

[0033] Reference Figures 1-3In one embodiment, the outer casing assembly 20 includes an outer casing body 201 and a plurality of third reinforcing ribs 202. The outer casing body 201 is disposed on the base plate 21. The support assembly 1 is located inside the outer casing body 201 and is connected to the outer casing body 201 and the base plate 21 respectively. The plurality of third reinforcing ribs 202 are disposed on the side of the outer casing body 201 near the electronic energy storage module.

[0034] In the above embodiment, the outer casing assembly 20 includes an outer casing body 201 and a plurality of third reinforcing ribs 202. The outer casing body 201 is an enclosed shell structure, mounted on a base plate 21, forming a closed accommodating space together with the base plate 21. A support assembly 1 is disposed inside the outer casing body 201, its function being to support and fix the electronic energy storage module. The bottom of the support assembly 1 is connected to the base plate 21, and its upper and side parts are connected to the outer casing body 201, forming a vertical and horizontal fixing structure, thereby tightly integrating the outer casing body 201, the support assembly 1, and the base plate 21. The electronic energy storage module is mounted on the support assembly 1, and the plurality of third reinforcing ribs 202... The third reinforcing rib 202 is located on the side of the outer shell 201 near the electronic energy storage module, specifically on the inner surface of the outer shell 201, that is, on the inner wall facing the electronic energy storage module. The third reinforcing rib 202 is distributed in a spaced or arrayed manner and is integrally formed with the outer shell 201. Its extension direction can be designed as longitudinal, transverse or grid-like according to structural requirements. Since the third reinforcing rib 202 is located inside the outer shell 201 and close to the electronic energy storage module, it can not only enhance the local structural strength of the outer shell 201 and prevent the shell from deforming due to external impact, but also participate in heat conduction to a certain extent, assist in heat dissipation, and jointly ensure the safe operation of the electronic energy storage module.

[0035] Reference Figures 1-5 In one embodiment, the housing assembly 20 further includes a handle 203. A receiving groove 204 is provided on the side of the housing body 201 away from the base plate 21. The receiving groove 204 is arranged correspondingly to the handle 203, and the handle 203 is located in the receiving groove 204 and is movably connected to the housing body 201.

[0036] In the above embodiment, the outer shell assembly 20 further includes a handle 203. The outer shell body 201 is composed of a front shell, a rear shell, a left side shell, a right side shell, and a top shell, forming a hexahedral frame structure. The front shell and the rear shell are two shell components arranged opposite to each other, respectively installed at the front and rear ends of the base plate 21. The left side shell and the right side shell are also shell components arranged opposite to each other, located on the left and right sides of the base plate 21, and connected to the corresponding sides of the front shell and the rear shell to form an enclosed structure. The top shell is located on the opposite side of the base plate 21, i.e., above, and is connected to the top edge of the front shell, the rear shell, the left side shell, and the right side shell to form a closed outer shell space. Multiple third reinforcing ribs 202 are respectively provided on the inner surface of the front shell, the rear shell, the left side shell, the right side shell, and the top shell, integrally formed or fixedly connected to each shell. A commissure is provided on the outer side of the top shell of the outer shell body 201. The receiving groove 204 is a recessed structure, corresponding to the handle 203. The handle 203 is a U-shaped structure and is movably connected to the receiving groove 204 to realize the retraction and extension function. The shape of the receiving groove 204 matches the handle 203, which is also U-shaped, to ensure that the surface of the handle 203 is flat after being stored. An inclined clearance groove is also provided in the middle of the receiving groove 204, which makes it easy for the user's fingers to reach in and hook the handle 203. The handle 203 is movably connected to the receiving groove 204 through a pivot or hinge structure, and can switch between the stored state (embedded in the groove) and the unfolded state (flipped outward). By setting the U-shaped handle 203 in the receiving groove 204 of the top shell, and cooperating with the inclined clearance groove, the handle 203 can be hidden and retracted, improving the appearance and operation convenience, while enhancing the overall structural strength of the shell.

[0037] Reference Figures 1-7 In one embodiment, the housing assembly 2 further includes a buffer assembly 23, which includes a support base 230 and a buffer pad 231. The support base 230 is disposed on the side of the base plate 21 away from the reinforcing rib assembly 22. A buffer groove is provided in the support base 230, and the buffer pad 231 is disposed in the buffer groove.

[0038] In the above embodiment, the housing assembly 2 further includes a buffer assembly 23, which includes a support base 230 and a buffer pad 231. The support base 230 is disposed on the side of the base plate 21 away from the reinforcing rib, i.e., the bottom surface of the base plate 21, forming an external support structure for the entire equipment. The support base 230 is a rigid structural component, usually made of plastic or metal, and is fixedly connected to the bottom of the base plate 21. It has a recessed buffer groove inside, which is an embedded cavity used to install and position the buffer pad 231. The buffer pad 231 is disposed on the support base 230. The buffer groove of the support 230 is made of silicone, which can absorb external impact during the placement or movement of the equipment. The thickness of the buffer pad 231 is greater than the depth of the buffer groove. This means that when the buffer pad 231 is pressed into the buffer groove, part of its volume will protrude from the surface of the support 230, forming an exposed elastic contact surface. Therefore, when the equipment is placed on a horizontal surface, the buffer pad 231 first contacts the ground, bears the main pressure, and uses its elastic deformation to achieve anti-slip, shock absorption and height compensation functions, thereby improving the stability and service life of the equipment.

[0039] Reference Figures 1-7 In one embodiment, the support component 1 includes a support frame 10 and a support plate 11. The support frame 10 is disposed on the base plate 21 and connected to the housing component 20. The support frame 10 is used to install the battery pack of the electronic energy storage module. The support plate 11 is disposed on the side of the support frame 10 away from the base plate 21. The support plate 11 is used to install the control circuit board of the electronic energy storage module.

[0040] In the above embodiments, the support component 1 includes a support frame 10 and a support plate 11. The support frame 10 is a rigid skeleton structure, mounted on the base plate 21 and connected to the outer casing component 20. The main function of the support frame 10 is to support and fix the battery pack in the electronic energy storage module. The support plate 11 is located on the side of the support frame 10 away from the base plate 21, i.e., at the upper part of the support frame 10, serving as a mounting platform for the control circuit board. The support plate 11 is typically a flat plate or a structural component with mounting holes, used to fix the control circuit board and stably position it above the battery pack. The electronic energy storage module consists of a battery pack and a control circuit board assembly. The battery pack is installed inside the support frame 10, and the control circuit board is installed on the support plate 11. The two are electrically connected by wires or connectors to form a complete power management unit. The control circuit board is not only connected to the battery pack, but also connected to the electronic components and sockets on the front shell to realize power output to external devices and system status display. The left and right side plates of the outer shell assembly 20 are provided with cooling fans and heat dissipation holes, which are arranged in a corresponding position to the control circuit board to form a directional air duct. This allows the heat generated by the control circuit board during operation to be forcibly discharged by the fans and conducted to the external environment through the heat dissipation holes, effectively reducing the internal temperature.

[0041] Reference Figures 1-7 In one embodiment, the support frame 10 is provided with a plurality of battery compartments 12 for placing the battery pack. The battery compartments 12 are recessed toward the support plate 11, and a second arc-shaped structure 13 corresponding to the first arc-shaped structure of the third rib 2203 is provided at the bottom of the battery compartments 12.

[0042] In the above embodiment, the support frame 10 is provided with multiple battery compartments 12. Each battery compartment 12 is an independent cavity for accommodating and positioning the battery pack. The number of battery compartments matches the number of individual batteries in the battery pack. The battery compartments 12 are recessed towards the support plate 11, that is, recessed downward from the upper surface of the support frame 10 to form a receiving space with a certain depth for embedding and installing the battery pack. At the bottom of the battery compartment 12, that is, in the area where the battery pack contacts the support frame 10, a second arc-shaped structure 13 is provided. This structure is an arc-shaped curved surface that protrudes towards the bottom plate 21, and its shape is adapted to the upper outer surface of the cylindrical battery. The first arc-shaped structure of the third rib 2203 corresponds to the second arc-shaped structure 13 at the bottom of the battery compartment 12, and together they act on the upper and lower arc-shaped surfaces of the cylindrical battery. When the battery pack is composed of multiple cylindrical batteries, its outer contour is a continuous arc-shaped surface. The lower arc surface of the battery pack fits into the second arc-shaped structure 13 at the bottom of the battery compartment 12, while the upper arc surface corresponds to the first arc-shaped structure of the third rib 2203, forming a bidirectional arc-shaped covering support. This allows the battery pack to be clamped by the upper and lower arc-shaped structures in the vertical direction, which not only improves the stability of the installation, but also enhances the vibration resistance of the overall structure.
