[0026] This application provides an energy storage power supply, including a housing, a pull rod, and a pressure plate. The housing includes an outer side surface and a mounting groove is formed on the outer side surface. The pull rod is disposed on the mounting groove. The pressure plate is detachably fixed to the housing to press the pull rod against the mounting groove.

[0027] In the energy storage power supply of this application embodiment, by providing an installation groove on the outer side of the housing and using a detachable fixing plate to press the pull rod against the installation groove, on the one hand, the pull rod and the housing can be detachably assembled. When the pull rod is damaged due to long-term use or the user needs to replace it, the pressure plate can be directly removed to take out the pull rod for replacement, without replacing the entire housing or performing destructive repairs, thus reducing maintenance costs and maintenance time. On the other hand, the pressing and fixing method of the pressure plate can ensure the structural stability of the pull rod after installation, avoid problems such as loosening and displacement during use, ensure reliability when used in mobile applications, and meet the diverse use and maintenance needs of users.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 This is a front view structural diagram of an energy storage power supply 100 provided in some embodiments of this application. Figure 2 This is a three-dimensional structural schematic diagram of the energy storage power supply 100 provided in some embodiments of this application.

[0029] The energy storage power supply 100 can be a portable energy storage power supply with a large capacity. The energy storage power supply 100 includes a housing 10, a pull rod 20, a pressure plate 30, and a battery.

[0030] The housing 10 is the core load-bearing component, providing space for the battery. The housing 10 can adopt various structures. In some embodiments, the housing 10 may include a first part and a second part, which overlap each other, jointly defining the space for accommodating the battery. The second part can be a hollow structure with one open end, while the first part can be a plate-like structure, covering the open side of the second part so that the first and second parts jointly define the space. Alternatively, both the first and second parts can be hollow structures with one open side, with the open side of the first part covering the open side of the second part. Of course, the housing 10 formed by the first and second parts can be of various shapes, such as a cuboid or a cylinder. The housing 10 may have several longitudinal reinforcing ribs and transverse support columns inside. The thickness of the reinforcing ribs is consistent with the basic wall thickness of the housing 10. The support columns are cylindrical or square, evenly distributed at the bottom and sides of the housing 10, further improving the deformation resistance and load-bearing capacity of the housing 10.

[0031] The housing 10 can be manufactured using a one-piece injection molding process, and the material is selected from high-strength engineering plastics, such as ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), or ABS / PC composite material. In addition, glass fiber reinforcement is added to the material to balance structural strength and insulation properties. The housing 10 needs to reach a certain flame retardant rating to adapt to the safe use scenarios of the energy storage power supply 100. When the housing 10 is a cuboid, the corners of the housing 10 can all adopt a rounded corner transition design, and the radius of the rounded corners is not limited. In this way, sharp corners can be used to avoid scratching users or causing damage from bumps and knocks, and the rounded appearance of the product can be improved.

[0032] The housing 10 includes an outer surface, which serves as the external bearing surface of the energy storage power supply 100. When the housing 10 is cuboid, the outer surface has a flat rectangular planar structure. The length and width of the outer surface are adapted to the capacity specifications of the energy storage power supply 100 and are not limited in specific dimensions. The edges of the outer surface smoothly transition with the top, bottom, and side end faces of the housing 10 to avoid forming sharp steps. A mounting groove 101 is formed on the outer surface.

[0033] The pull rod 20 is telescopically mounted within the mounting slot 101. The pull rod 20 can employ a multi-segment telescopic structure, consisting of at least two nested telescopic tubes with progressively decreasing inner diameters. The telescopic tubes are made of high-strength aluminum alloy or carbon fiber composite material, balancing lightweight design with structural strength. The maximum telescopic length of the pull rod 20 is adapted to the volume of the energy storage power supply 100. A handle 21 is also provided at the top of the pull rod 20. The handle 21 has an anti-slip texture with wavy or diamond-shaped protrusions to increase friction during gripping and prevent slippage. The handle 21 has an ergonomic arc shape and an embedded metal liner, which is fixedly connected to the telescopic tube at the top of the pull rod 20. Users can pull part of the lever 20 out of the mounting slot 101 by holding the handle 21 of the lever 20 to move the energy storage power supply 100. When the lever 20 is not in use, the lever 20 can be fully retracted into the mounting slot 101 by holding the handle 21.

[0034] The pressure plate 30 can be made of metal or high-strength plastic. The pressure plate 30 is detachably fixed to the housing 10 to press the pull rod 20 against the mounting groove 101. The pressure plate 30 can be manufactured using a one-piece stamping process, and its total length is adapted to the length of the mounting groove 101. There can be multiple pressure plates 30; for example, there can be two, three, four, or even more. In this embodiment, there are two pressure plates 30, one located at the bottom of the pull rod 20 and the other located on the handle 21 near the pull rod 20.

[0035] Please refer to further information. Figure 2In some embodiments, the housing 10 includes two reinforcing ribs 11 extending upward from the outer side, the two reinforcing ribs 11 being spaced apart and extending along a first direction Z to form a mounting groove 101 between the two reinforcing ribs 11, the first direction Z being substantially parallel to the outer side.

[0036] It is worth noting that the first direction Z can be the extension and retraction direction of the pull rod 20, or the height direction of the energy storage power supply 100. Two reinforcing ribs 11 extend linearly along the first direction Z parallel to the outer surface, maintaining a preset interval between them. This interval is adapted to the cross-sectional width of the pull rod 20, forming a mounting groove 101 between the two reinforcing ribs 11 to accommodate the pull rod 20. The height of the reinforcing ribs 11 is higher than the cross-sectional height of the pull rod 20 (the thickness of the pull rod 20 along the direction perpendicular to the outer surface), meaning that the pull rod 20 does not extend beyond the mounting groove 101. Furthermore, the top edge of the reinforcing ribs 11 can be rounded to prevent sharp edges from scratching the pull rod 20 or the user.

[0037] Thus, by using two reinforcing ribs 11 that are spaced apart along the first direction Z and extend upward on the outer side of the housing 10, on the one hand, they can directly enclose and form the mounting groove 101 for accommodating the tie rod 20, eliminating the need for an additional mounting groove 101 structure, simplifying the overall processing technology and assembly steps of the housing 10, and reducing manufacturing costs; on the other hand, due to the reinforcing effect of the reinforcing ribs 11 on the structural strength of the housing 10, the wall thickness of the housing 10 in the area corresponding to the mounting groove 101 can be reasonably reduced, reducing the amount of raw materials used in the housing 10 while ensuring the reliability of structural support, thereby reducing manufacturing costs.

[0038] Please see Figure 2 In some embodiments, the mounting groove 101 is located substantially at the middle of the outer side in the second direction X, which is substantially perpendicular to the first direction Z.

[0039] It is worth noting that the plane formed by the second direction X and the first direction Z is parallel to the outer surface. The second direction X can be the length direction of the energy storage power supply 100. The mounting groove 101 is located in the middle region of the outer surface of the housing 10 in the second direction X. The middle region is determined by the geometric center of the outer surface of the housing 10, that is, the center line of the mounting groove 101 coincides with the center line of the outer surface of the housing 10 in the second direction X. The length of the mounting groove 101 in the second direction X can be 1 / 3 to 1 / 2 of the total length of the outer surface of the housing 10 in the second direction X, ensuring that the stress point of the pull rod 20 is aligned with the center of gravity of the entire energy storage power supply 100 after installation. The two ends of the mounting groove 101 along the second direction X maintain a preset safe distance from the edge of the outer surface of the housing 10 to avoid damage to the edge of the housing 10 due to stress concentration.

[0040] Thus, by setting the mounting groove 101 in the middle of the outer side of the housing 10 along the second direction X, the force point of the pull rod 20 can be matched with the center of gravity of the energy storage power supply 100, avoiding problems such as unilateral tilting and dragging difficulty due to force offset during the pulling process. In addition, this central layout can make the stress distribution on the outer side of the housing 10 more uniform, preventing deformation or damage to the housing 10 due to local force concentration.

[0041] In some embodiments, along the first direction Z, the length of the reinforcing rib 11 is equal to the length of the outer side surface.

[0042] Specifically, the length of the reinforcing rib 11 along the first direction Z is equal to the length of the outer surface of the housing 10 along the first direction. That is, one end of the reinforcing rib 11 extends along the first direction Z to the edge of the first end of the outer surface of the housing 10, and the other end extends along the first direction Z to the edge of the second end of the outer surface of the housing 10. Both ends of the rib are smoothly connected to the end sidewalls of the housing 10. Furthermore, the outer surface of the through-rib is flush with the outer surface of the housing 10, without any protrusions or depressions.

[0043] Thus, by ensuring that the length of the reinforcing rib 11 is equal to the length of the outer side along the first direction Z, the stress transmission path of the rib can be further extended, avoiding stress concentration in a local area of ​​the mounting groove 101. This significantly improves the overall structural strength and bending resistance of the outer side of the housing 10, effectively preventing cracking and deformation of the housing 10 when the pull rod 20 is pulled for a long time. At the same time, the length of the mounting groove 101 is matched with the contact length of the pull rod 20, making the pull rod 20 more evenly stressed. Combined with the pressing action of the pressure plate 30, this further reduces the probability of the pull rod 20 shaking or shifting during use.

[0044] In some embodiments, the mounting groove 101 sinks downwards from the outer side. Specifically, the mounting groove 101 sinks inwards from the outer side of the housing 10 in a direction perpendicular to the outer side to form a groove structure. The sinking depth is adapted to the cross-section of the pull rod 20, so that the outer surface of the pull rod 20 does not protrude from the outer side of the housing 10 after installation. In addition, multiple limiting ribs may be provided at the bottom of the mounting groove 101. The limiting ribs facilitate the limiting and installation of the pull rod 20. The multiple limiting ribs can act as a keel, strengthening the structural strength of the housing 10 and preventing deformation of the housing 10.

[0045] Thus, by recessing the mounting groove 101 from the outer side of the housing 10, the recessed mounting groove 101 allows the pull rod 20 to be fully embedded inside the housing 10, effectively reducing the space volume of the pull rod 20 protruding from the outer side of the housing 10, making the overall structure of the energy storage power supply 100 more compact.

[0046] Please see 1 and Figure 2In some embodiments, the pressure plate 30 includes a contoured portion 31 and a fixing portion 32. The contoured portion 31 includes a bent piece that forms a fit with the cross section of the pull rod 20. The fixing portion 32 includes fixing ears located at both ends of the contoured portion 31. The pressure plate 30 is configured to fix the fixing portion 32 to the outer side by fasteners 33, so that the contoured portion 31 covering the pull rod 20 presses the pull rod 20 against the mounting groove 101.

[0047] Specifically, the contoured part 31 can be integrally formed by bending process, with the bending angle precisely matching the cross-section of the pull rod 20. The inner sidewall of the contoured part 31 can be fitted with a silicone buffer pad, which can be integrally formed with the pressure plate 30 through in-mold injection molding process. This can increase the friction between the pressure plate 30 and the pull rod 20, preventing the pull rod 20 from sliding axially in the mounting groove 101, and also prevent the metal pressure plate 30 from directly contacting the pull rod 20 and causing surface scratches. At the same time, it can alleviate the vibration and impact generated during the pulling process.

[0048] The fixing part 32 consists of symmetrically arranged fixing ears at both ends of the contouring part 31. The fixing ears are flat and have rounded edges to prevent sharp edges from scratching installers or damaging the surface of the housing 10. A through mounting hole can be provided on the fixing ear, the diameter of which matches the outer diameter of the fastener 33. Multiple mounting holes are possible. The fastener 33 can be a screw, bolt, or screw. The pressure plate 30 is threadedly connected to a pre-drilled threaded hole on the outer side of the housing 10 via the fastener 33 through the mounting hole, causing the bent piece of the contouring part 31 to press tightly against the outer surface of the pull rod 20, thus securely limiting the pull rod 20 within the mounting groove 101.

[0049] Thus, by adopting an integrated structural design of the contouring part 31 and the fixing part 32 for the pressure plate 30, the bending piece of the contouring part 31 and the cross-section of the pull rod 20 form a precisely matched covering structure, which can apply a uniform pressing force to the pull rod 20 and avoid local stress concentration that could cause deformation or damage to the pull rod 20. At the same time, the fixing ears located at both ends of the contouring part 31 are detachably fixed to the outer side of the housing 10 by fasteners 33, which realizes convenient disassembly and assembly of the pressure plate 30 and the housing 10, making it easy to replace the pull rod 20 separately in the future, and also ensuring the connection strength of the pressure plate 30 after installation, preventing the pressure plate 30 from loosening during the pulling process.

[0050] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the energy storage power supply 100 also includes a decorative cover 40, which is detachably fixed to the housing 10 and covers the pull rod 20.

[0051] Specifically, the shape of the decorative cover 40 matches the contour of the corresponding area of ​​the mounting groove 101, and it can be detachably fitted into the mounting groove 101. Furthermore, the outer surface of the decorative cover 40 is flush with the outer side surface, and the inner surface of the decorative cover 40 can have multiple reinforcing ribs. The decorative cover 40 also has one or more countersunk holes 401, and a protruding stud 13 can be formed in the mounting groove 101 at a corresponding position. The decorative cover 40 can be fixedly connected to the stud 13 via a connector passing through the countersunk hole 401, so that the decorative cover 40 can be detachably fixed to the housing 10. The connector can be a screw, bolt, or screw, etc., and is not specifically limited.

[0052] Thus, by detachably fixing the mounting slot 101 to the mounting slot 101 and covering the pull rod 20, on the one hand, components such as the pull rod 20, pressure plate 30, and fasteners 33 can be hidden inside the decorative cover 40, avoiding exposed components from affecting the neatness and coordination of the product's appearance and improving the visual aesthetics of the energy storage power supply 100; on the other hand, the decorative cover 40 can form a protective barrier, effectively preventing dust, impurities, etc. from entering the mounting slot 101 and the connection part of the pull rod 20, reducing component wear and corrosion, and extending the service life of the pull rod 20 and the mounting structure; in addition, the decorative cover 40 adopts a detachable fixing method, which does not affect the convenience of subsequent disassembly of the pressure plate 30 to replace the pull rod 20, and can also form an auxiliary limit for the pressure plate 30 after assembly, further preventing the pressure plate 30 from loosening and enhancing the stability of the overall structure.

[0053] In some embodiments, the decorative cover 40 is made of transparent plastic. For example, the decorative cover 40 is made of polycarbonate (PC) or acrylic (PMMA) with a light transmittance of not less than 90%, ensuring that the user can clearly observe the internal structure within the mounting groove 101. The thickness of the decorative cover 40 can be 2-5 mm, combining light transmittance with structural strength. The surface is treated to resist scratches, improving durability. Furthermore, the inner wall of the decorative cover 40 may be provided with a dustproof coating to reduce dust adhesion without affecting the light transmittance. The edges of the decorative cover 40 are rounded to maintain consistency with the shape and style of the housing 10.

[0054] Thus, by making the decorative cover 40 out of transparent plastic, on the one hand, users can directly observe the installation status, wear condition, and fixing reliability of the pressure plate 30 without disassembling the decorative cover 40, improving the convenience of use and maintenance; on the other hand, the transparent plastic material is lightweight and easy to process, which can reduce the production cost of the decorative cover 40, while still effectively preventing dust and impurities from entering the mounting groove 101, ensuring the service life of the pull rod 20 and connecting parts.

[0055] Please see Figure 3 and Figure 6In some embodiments, the housing 10 includes a plurality of buckles 12 formed on the outer side, and the decorative cover 40 includes a plurality of sliders 41 that engage with the plurality of buckles 12. The decorative cover 40 is detachably connected to the housing 10 by sliding into the plurality of buckles 12 through the plurality of sliders 41.

[0056] Specifically, multiple undercuts 12 are integrally formed on the outer surface of the housing 10. These undercuts 12 are evenly distributed along the length of the mounting groove 101, and each undercut 12 protrudes away from the outer surface of the housing 10. Multiple sliders 41 are provided on the inner wall of the decorative cover 40 corresponding to the positions of the undercuts 12. The number of sliders 41 is the same as the number of undercuts 12, and the shape of the sliders 41 matches the contour of the undercuts 12. When installing the decorative cover 40, the sliders 41 are aligned with the guide direction of the undercuts 12, and the decorative cover 40 is pushed along the first direction Z, causing the sliders 41 to slide into the gap between the undercuts 12 and the outer surface of the housing 10, achieving a snap-fit ​​connection. When disassembling, the decorative cover 40 is pulled in the opposite direction to disengage the sliders 41 from the undercuts 12, completing the disassembly of the decorative cover 40.

[0057] Thus, the decorative cover 40 is detachably connected through a sliding snap-fit ​​structure in which multiple sliders 41 engage with multiple inverted buckles 12 on the outer side of the housing 10. On the one hand, the decorative cover 40 can be quickly disassembled and assembled without the need for additional fasteners, making the operation simple and efficient. This allows users to easily remove the decorative cover 40 to check the status of the pull rod 20 at any time, and also allows it to be quickly reset after maintenance, greatly improving the convenience of maintenance operations. On the other hand, the snap-fit ​​engagement between the inverted buckles 12 and the sliders 41 has good connection stability, which can effectively prevent the decorative cover 40 from loosening or falling off during the movement or transportation of the energy storage power supply 100, ensuring the continuity of the protective and aesthetic effects.

[0058] Please refer to further information. Figure 6 In some embodiments, the undercut 12 includes a first guide surface 121 and a first mating surface 122, and the slider 41 includes a second guide surface 411 that mates with the first guide surface 121 and a second mating surface 412 that mates with the first mating surface 122. The first guide surface 121 and the second guide surface 411 are inclined relative to the outer surface, and the first mating surface 122 and the second mating surface 412 are substantially parallel to the outer surface.

[0059] The first guide surface 121 is an inclined surface set at an angle relative to the outer side of the housing 10, with an inclination angle of 30°-60°. The first mating surface 122 is a plane perpendicular to the first direction Z and substantially parallel to the outer side of the housing 10. The inclination angle of the second guide surface 411 is the same as that of the first guide surface 121, allowing it to fit tightly against the first guide surface 121. The second mating surface 412 is a plane parallel to the first mating surface 122. When the slider 41 is fully slid into the inverted buckle 12, the second mating surface 412 and the first mating surface 122 abut against each other, forming a stable limiting structure. Both the inverted buckle 12 and the guide surface of the slider 41 are smoothed to reduce friction during sliding. The mating surfaces are provided with anti-slip textures to enhance the connection stability after mating.

[0060] Thus, the inclined first guide surface 121 of the inverted buckle 12 is adapted to the second guide surface 411 of the slider 41, which can play a guiding role in the installation of the decorative cover 40, so that the slider 41 can quickly slide into the mating position of the inverted buckle 12 along the guide surface, reducing the assembly difficulty and improving the assembly efficiency. The first mating surface 122 and the second mating surface 412 of the inverted buckle 12 and the slider 41, which are basically parallel to the outer side of the shell 10, fit together and abut against each other, forming a stable limiting structure, which effectively restricts the displacement of the decorative cover 40 in the direction perpendicular to the outer side, and prevents the decorative cover 40 from loosening or lifting during the movement and bumping of the energy storage power supply 100.
